Climate Change Effects On Water Resources Environmental Sciences Essay

The last two decennaries climate alteration is increasing due to the alteration of human activity such as autos, planes, mill and other beginnings we use that adds nursery gases to the ambiance. Because of these human causes the Earth is heating up. One consequence that clime alteration has is the consequence the alteration will hold upon human H2O fresh water resources. I believe that clime alteration will hold an consequence on human H2O resources because of the close connexions with the hydrological rhythm, the raising temperature will increase in inundations and drouths that will take to the demand on more freshwater resources. Climate alteration has close connexions with the hydrological rhythm. The hydrological rhythm is located in the Earths hydrosphere this is the country in around Earth which holds all the H2O. The H2O is moved around the Earths hydrosphere in a rhythm. The hydrological rhythm is moved in five different stairss – vaporization, precipitation, condensation, overflow, aggregation and infiltration. The as you can see in Figure 1 the hydrologival rhythm all starts of with vaporization this is the alteration of liquid H2O to H2O vapor. The following measure is condensation this is the procedure of altering H2O vapor, from a liquid and so to organize clouds as you can see from the clouds in figure 1. This procedure can be notice for illustration when you look out for dew on the land in the forenoon. As the clouds you see in the sky move around Earth distributing the H2O vapor from topographic point to topographic point. The clouds become over laden with wet so they have to let go of th e overladen wet. They release the wet by a procedure called by precipitation which is normally rain, hail or snow. Infiltration occurs they when all the precipitations lay on the land. If there is to much precipitation on the land this becomes overflow. Runoff stays on the Earth land and runs into watercourses, rivers, lakes and oceans. So when the precipitation run into the these watercourses, rivers, lakes and oceans this procedure is called aggregation. As infiltration, overflow and aggregation are being processed, the Sun is doing a the rhythm to return back to the begaining of the rhythm to the procedure called evaporation.Sunlight heats up the liquid in watercourses, rivers, lakes and oceans. The warm air rises upwards into the ambiance and becomes the vapor involved in condensation. Without this procedure life on Earth would be impossible. Fresh water that we use in or twenty-four hours to twenty-four hours lifes normally comes from Aquifer, Streams, Rivers, Lakes. Aquifer are constructed when stones of the upper portion of the Earth ‘s crust contain holes or pores. Thesiss holes are large or joined together so that H2O can flux through them easy. This is a portion of stone that is easy for H2O to go through through known as permeable. Streams normally get most of its H2O from overflow, rain and thaw snow. A watercourse is formed when the rain and runing snow met at the same topographic point and acquire into a line of channel. Streams usely flows into lakes, rivers, aquifer and seas. Rivers are a natural watercourse of fresh water resource. Water within the river is by and large collected from precipitation through surface overflow, groundwater recharge, springs and the release of stored H2O in ice and runing glaciers. Lakes are normally filled with deep fresh water or salt H2O. Lakes are inland usly on mountains countries and are non portion of the Ocean. They are filled by rivers or watercourses that connect to them. Some Lakes can be adult male made and are constructed for industrial or agricultural usage and even for hydro- electric power or domestic H2O supply. Water is one of the most importent inputs the human organic structure demands for us worlds to get by with mundane life. We need it for so many things e.g. wellness, turning nutrient, irrigation, industry. Despite the importance of Freshwater Resources decreasing, we are get downing to take the fresh water resources for granted. Most of the fresh water we use is wasted and polluted. Because the hydrological rhythm temperature is lifting it will take to a alteration in the horological rhythm, This will hold an impact on the conditions. The dry seasons will go alot more drier and the wet seasons will go alot more wetter. Leaving us with more inundations and drouths. This alteration will therefore will leave the handiness and quality of H2O. Some of the states on this Earth already hold a difficult enouch clip acquiring H2O because of increaseing industrial pollution and population growing. Climate alteration merely adds to the job to the quality of H2O, which in some parts of the universe the cut down rainfall and lifting temperatures decrease the fresh water. By the twelvemonth 2025 most of worlds populating in states with hapless H2O quality degrees will increase from about 34 per centum ( in 1995 ) to 63 percent.R K Pachauri ( 2005 ) The alteration in accessing H2O stressed countries will hold a possible struggle. As there will be a pressured demand on fresh water because of family, agricultural and industrial utilizations. These struggles will happen in H2O stressed countries contending against countries of natural springs and rivers every bit good as this it will take to conflict on boundary countries for illustration the part of Northern Kenya and the Samburu is holding to get by with the altering forms of rainfall and dry periods which with other force per unit areas on the natural resources are taking to increasing struggle among tribal groups over entree to scarce water.Smith ( 2006 ) 2 Discussion Most of the Earth has 70 % of ocean. While merely 30 % of the Earth is land. Around 84 % of the universes population is populating on dry land. Worlds are seeking to repair this by Reconstruction the hydrological rhythm system by constructing dikes and making waste H2O intervention workss etc. These elements will supply H2O for agribusiness, family, Industrial, environmental and other utilizations. But these alterations will besides take to some defects in old ages to come. India is one of the most effected by clime alteration. The snow ice caps of the Himalayas is sing less snow because of snow thaw. The glaciers is runing and there is marks of addition implosion therapy. The increasing rise temperatures is get downing to dry up the rivers. The Himalayas holds the largest sum ice on the Earth. Research workers have figure out that there is a strong combination between snow and the temperature. In recent old ages the Himalayas have experienced warm periods in the old ages between 1960- 1990, doing a decrease in snow autumn. Glaciers has been watched by research workers in the the past old ages. The United Nations clime study predicts by 2035 some Himalayan glaciers will vanish with the lifting temperatures. Because of the glaciers runing the thaw ice will run off into rivers such as the Indus, Ganges and Brahmaputra rivers and some feeders coming from the Himalayan ice field. This will do deluging to riverside citations e.g. Varanasi, Kanpur and Patna. These metropolis ‘s have a population of 1000000s and have already see inundations during high monsoon season and it will be ongoing. Deluging will besides do break for the farming countries in northern parts of India and cause harm to the roads and rail manner line. The dikes such as the dike in Kosi autonomic nervous systems Sutlej could over flux doing more devastation to corn fields and colonies. When the point of no ice is reached by 2035 the ice thaw will hold either stopped because of a solution to climate alteration or be dried up because of the continued temperature lifting. If the ice does get down to understate the river will go weaker and drier during the monsoon oral cavities and summer. As the earths temperatures rises from about 14 grades C based in 2000 to a estimated 19 grades C in 2100 the undermentioned effects will be cause by the addition ; Agricultural, Household, Industrial, Environmental and wellness sea degrees will lift to an estimated 3.9 in to estimated 35 by 2100. Some parts of the coastal citations around India e.g. Mumbai, Chennai, Kolkata and other parts of the universe will be submerged. Even most of the island around India will be covered in H2O. The island of Lohachara is the first island in the universe to be covered in H2O due to climate alteration. The island is located on the southern border of the Ganges delta in the bay of Bengal. Its 10,000 occupants became the first refugees created because of clime alteration. There is a group of 27 island called Lakhadweep around the Arabian sea off the seashore of south Indian province Kraal. They have a population of about 61,000 people populating on them. The low prevarication islands are in immense danger of being covered in H2O every bit good. India is one of the universe biggest state that effects the nursery consequence. With the increased temperatures they will make a addition in precipitation. Rising the procedure of vaporization ensuing from warmer sea temperatures in the Indian ocean and Arabian Sea will increase that destroy procedure around the West Indian Rajasthan Desert Equally good as the H2O resources being shorten because of clime alteration there is besides another job and that is that normally boundary states sometime portion the same H2O resource. There is some indenture that there has been conflict over fresh water shared by two or more states. Freshwater is really of import to all the universes Humans activity, including the Agricultural, Household, Industrial and Environmental. But bad direction and the impact of clime alteration can take to tenseness ‘s between different states. For some old ages the counties such as India and Bangladesh have encountered struggle on river resources. It all started In 1993 when India and Bangladesh came under force per unit area when the Ganges River started to make its record depressions. Because the H2O degree was low it affected Bangladesh agricultural and killed most of its harvests. In October 1995, The Prime Minister of Bangladesh addressed the United Nations ( UN ) .The premier curate called Indiais portion of river H2O resources ia gross misdemeanor of human rights and justice.i Indiais constitution of the Farrakka Barrage which is a bombardment built near the boundary line of Bangladesh. The bombardment was build was to separate H2O for the Calcutta port. But Bangladesh says that because of this separation it has resulted in falling H2O tabular arraies and greater H2O resources for Bangladesh. India has a different position of the issue. Indian leaders says that Bangladesh was incorrect in depicting this issue. Bangladesh has asked India for a iminimum guaranteei understanding which will give Bangladesh a minimal flow of H2O. In 1996 India and Bangladesh agreed in the understanding so the iTreaty on the Sharing of the Waters of the Gangi was signed. Some political leader were unhappy about the understanding. But it was accepted my most political leaders. Since the pact Bangladesh continues to hold a figure of jobs. Some of the understandings that was agreed in the pact have non been met. How are we traveling to repair this job is the inquiry we need to inquire ourselfs I can see from my research that some attempts are being made to better direction in freshwater resources. Different organiseions have been developed to assist the mather of clime alteration for illustration, the United Nation ( UN ) have organised the first H2O conference to take topographic point in 1977 and developed an action program to take action on the improved direction and development of H2O resources and the UN designated 2003 as the international twelvemonth of freshwater resources. The mission of the organision is to increase consciousness of the importance of fresh water usage, direction and protection, provide an chance to alter the execution of the rules of incorporate H2O resources direction, utilize the twelvemonth as a platform for advancing bing activity and spearheading new enterprises in H2O resources at the international, regional and national degrees, and Launch the universe H2O d evelopment study at the 3rd universe H2O forum in Kyoto. The World Summit on Sustainable Development ( WSSD ) 2002 has emphasised on the development of an incorporate H2O resources direction and H2O efficiency plan.DEVELOPMENT ( 2003 ) . Global Water Partnership ( GWP ) Is a web of bureaus and intuitions to advance iintegrated H2O resource managementi in developing states. It facilitates the exchange of cognition, experience and practise related to H2O resources management.Partnership ‘s ( 2010 ) . World Water Council ( WWC ) is an international think-tank for H2O issues. It nonsubjective is to iincrease protagonism for improved H2O resources managementi . WWC has been organizing the World Water Forum ( WWF ) bi-annually. The 3rd Forum was held in Japan in March 2003.Council ( 2010 ) . European Water Association Act as a focal point for the exchange of information related to H2O and H2O activities.Association ( 2010 ) 3 Decision I can reason that because of clime alteration and the hydrological rhythm it is holding a little long term consequence on human H2O resources. I can see that it has close connexions with the hydrological rhythm. Because of this it will increases implosion therapy, create dry lands and brush struggle within states. More acceleration to the hydrological rhythm may ensue in more terrible conditions and utmost conditions.Anne E. Egger ( 2003 ) If we do n't turn to this issue there will be farther more jobs in the hereafter and lead to even more drouths and implosion therapy. Harmonizing to the Comprehensive Assessment Of Water Manage in Agriculture, one in three people are already facing H2O deficits ( 2007 ) . Almost one-fifth of the worldis population, live in countries of physical scarceness. Climate alteration has a close connexion between hydrological rhythm. Rising temperatures will increase the altering liquid to vapour and take to the additions in rainfall and snowfall. Because of this the overall supply of freshwater resources will increase, Droughts and inundations will go on more often and alterations in snowfall and snow thaw are expected in cragged countries more often. Reading about clime alteration has made me let go of that we take our fresh water for granted and do n't believe about what will go on if we lose the fresh water. Will we hold to present H2O charges maintain better H2O systems.

Great Gatsby Review Paper

Great Gatsby Review————————————————- CERTIFICATE OF AUTHORSHIP COMP 1500: College Writing Farquhar College of Arts and Sciences Division of Humanities Submitted by: Assignment Number: 1 Assignment Title: The Great Gatsby Review Date: March 16, 2013 CERTIFICATE OF AUTHORSHIP: I certify that I am the author of this paper and that any assistance I received in its preparation is fully acknowledged and disclosed in the paper. I have also cited any sources from which I used data, ideas, or words, either quoted directly or paraphrased.I also certify that this paper was prepared by me specifically for this course. Student’s Signature: The Great Gatsby I’m known to be a very picky reader. I judge titles, the size of font, and the cover illustration. With all this in mind, I thought I would hate the Great Gatsby by F. Scott Fitzgerald. On the contrary, this book was a p age turner, and I constantly found myself at the edge of my seat biting my nails in anticipation. The descriptions in this book helps you imagine and greet the characters so vividly.Fitzgerald shows  an excellent understanding of lives that contain the great American Dream of being a millionaire and being happily married, yet are corrupted by greed. The more you read into the novel, the more you get pulled into a twisted love story. In the beginning of the novel, I was a little lost. I couldn’t understand who goes to an extravagant mansion party without knowing who the host is, or why nobody tried to find out. Luckily, our narrator, Nick, goes searching for this host.A drunken man wearing owl glasses stumbles upon Nick and begins observing the novels on the large bookcase. To his surprise, all the novels are real and not a facade to make the host look intelligent. When I discussed this with my teacher, she said this may be a foreshadowing that resident of this wealthy commu nity use wealth to cover up their wrongdoings and moral decay. What is the host, Gatsby, hiding if he wasn’t getting credit for any of his parties? This mystery pulled me into the book and that’s when I began to love it.We soon meet the rich and romantic Gatsby and who seems like he has his whole life together. He’s well respected for being in the army, rich and handsome. Despite all the magic, it’s a cruel facade. Behind the glitter lies a sad story with gloom and intensity. The Great Gatsby shows his desire into harsh, vivid light. He is a character who is so perfectly and tragically characterized, as he forgot his honest past as Jay Gatsby, and lost Daisy, his true love, who perfectly plays her part as innocent malevolence.If that’s not enough, Gatsby must also compete with Tom, Daisy’s husband, who slyly watches while he boasts of his physique and wealth. The two struggle to play their position in this twisted love triangle, which harms countless victims. Among the disorder, seems to be the only one with true knowledge of what is right, but doesn’t stop the chaos. The relationship is a massacre where no one truly wins. All in all, The Great Gatsby is about deception and the American Dream.Fitzgerald blurs our view with reality of the harsh world, yet slyly lets us see clearly enough to see Nick’s view on the chaos. Because Gatsby represents the truth of the American Dream, Fitzgerald shows that it will only lead to the decay of innocence and trouble, as Gatsby did during his transition from an honest, to corrupt man. Fitzgerald delicately handles this complex scheme in a way I have never seen replicated in authors today. I enjoy the book because once you think you know what’s going to happen, Fitzgerald slyly flips the script perfectly.

Malware review

While technology in computing continues to rise, computer hackers and crackers are also evolving. Cracking even started at the early age of computer technology. It started from simple codes exploiting bugs in Operating Systems. And now, it becomes a hobby of some. Stealing passwords and exploiting computers are common way of cracking. Some people termed it as hacking. Everyday, anti-virus companies are also upgrading their systems since viruses and other harmful softwares are upgrading. Piracy is another story. It is an act of duplicating someone’s work and sells it. Before, it is not common and hardly be seen. But as devices and softwares are upgrading, duplications can be made in a split of seconds. For some consumers, it is good but for the industry, it is a disadvantage. Piracy is one of the major problems that media industry is facing. But, technology cannot be fathom; it is continuously evolving in exponential manner. Music publishers (the entertainment industry is the ones affected) released their cure or prevention for such exploitation. The program is called â€Å"rootkit†. Basically, its task is to hide copy protection on computers.   With its ability, people can no longer copy music. In this way, piracy can be prevented. But, Sony admitted that someday somehow people will try to crack its code and continue on pirating. But for sure, media industry’s cyber security personnel well not let crackers succeed. On the other hand, due its capability to control computers, rootkit was distinguished by most anti-virus software as a malware. On an article on Technology Review published by MIT and written by Wade Roush, Technology Review interviewed Bruce Scheiener a computer security guru. There, Scheiener discussed about the tool and its capabilities. In â€Å"When Copy Protection Becomes Malware†, the computer security guru specifically identified the work of the rootkit and why it is called a malware. Basically, malware is a form of software that can control the system. Some malwares are harmful. But in the case of Sony, it has no other functions except to hide copy protections on users’ computer. The reason why it is distinguished as malware is because of its capability to manipulate the system wherein the user’s freedom of the product is given limitations. Added by Scheiener, computer users or consumers often times do not know what they are buying. Advertisements are so broad that buyers only see the outside appearance of the capability of the product. Consumers do not know what else their product can do. With this weakness, rootkit see an opportunity. It can’t be distinguished by consumers as harmful except when their anti-virus reacts on it (after distinguishing it as a malware). But these days, rootkit is accepted by anti-virus companies as useful software and now freely preventing music from being copied. In my opinion, it is illegal and unethical to copy a product. The ethical nature of copy protection and its implementation on the other hand is discussed in relation to a new set of copyright laws called The Digital Millennium Copyright Act. This act protects the media industry. It punishes those people involved in illegal duplication of digital products. In some point, consumers do not freely get what they needed for a product. Consumers buy digital products to satisfy their needs. But with this technology, some consumer’s rights are somewhat by passed. If we try to look at some point, there is a contradiction. Consumers wanted to buy a product that will make their lives easy. But this objective is not met since producers have the capability to control the product they want to sell. But, we can also say that it is a part of technology advancement. It is like before. There are no copying devices before so digital products are secured. It only came when the technology advances and devices able to duplicate are manufactured. Digital products vendors are only upgrading their system. They only restore what was lost. With the rootkit, digital products today have similar limitations before, except that it’s more advance and more easy to use. There’s another important thing the article discussed. The rootkit was not detected by anti-virus softwares before. There are people who know that Sony rootkit is freely exploring their computers. One of the reasons for this is that, Sony’s technology or program is more powerful than the anti-virus available that time. There were customers who noticed it. Some make noise that their anti-virus software did not detect the rootkit. It’s really shame on the part of anti-virus provider. Their software should be able to protect the computer from harmful viruses yet rootkit passed the test. We can picture out that programmers are getting their codes better in order to cross the gate which are set by protection softwares. However that did not last a long time. Anti-virus software providers developed further their products and able to detect the rootkit. Scheiener was asked if Sony will not make another program similar to rootkit. The guru said boldly that Sony will again do it when the controversy is over. Well, we cannot blame the company for it. They are only protecting their products from pirates. If more piracy will happen the digital industry will not also last for long. There will be no marketer on the said or similar products. It is also their way of saving their jobs and professions. Malware is really a big issue. Rootkit is not free from that controversy. The process will just create a cycle. There are people who will continue to find ways how to pirate a digital product. Crackers will continue to write codes in order to exploit bugs of every technology. While that is happening, cyber security personnel will find ways to prevent their products from being stolen. This is indeed an indication that we passed the days of low-technology and now experiencing a high-end digital technology. Nonetheless, copy protection will still be recognized as malware unless anti-virus provider withdraws its security on the program. Reference: Roush, W. (2006). When Copy Protection Becomes Malware.

Godfrey Hounsfeild Essay Example | Topics and Well Written Essays - 500 words

Godfrey Hounsfeild - Essay Example Furthering his career, he was employed at the Central Research Laboratories of the Electronic and Music Industry spearheading the completion of "Britain's first large solid-state computer and eventually adapting that design for use in transistors." These experiences ushered him to the idea of building the CT scanner. During 1967, Hounsfield hit the idea of building a computer-assisted tomography (CT) scanner, a computer which will aid in the analysis of X-ray data. His invention surpassed the traditional X-ray by presenting a more accurate picture of any organ in the human body. His device "use information from many X-ray scans of the same area, taken at different angles, to generate a composite image." Furthermore, this new machine is more convenient for patients as they can comfortably lie on their back during the whole examination. The precision and sensitivity of the CT scan made it important in the diagnosis and treatment of nuerological disorder. The revolution in technology facilitates the invention of more advanced CT scanners which can build images in less than a second and allows better spiral scanning.

The Internship in Sitio So Jos Agronegcios Assignment

The Internship in Sitio So Jos Agronegcios - Assignment Example Throughout the internship, I engaged in various activities. The main activities included: Understanding the operations of the factory, identifying possible sources of risks and hazards, and examining how hazards are communicated and handled within the factory. In addition, based on the findings, I proposed several measures that can be used to address the safety issues identified in the factory. By undertaking this internship, I was able to accomplish several learning outcomes. First, this helped me understand how safety standards are applied in a real working environment. Secondly, I gained the necessary experience in working with different people from varying backgrounds. The internship gave me the work experience needed to succeed in the job market. The main challenge was that I found it difficult to communicate with some of the workers at the factory, mainly because most of them were too busy to give me an audience. The internship was undertaken in the above-named factory at the start of June 2014. This is mainly a coffee factory that also deals with the growth and processing of sugarcane. In addition, the factory also engages in the production of feedlot beef. As a result, it is a fairly busy factory in which different activities are performed. As a student in safety management, this factory provided me with the opportunity to study issues related to safety. This factory is purely owned and run by the family. My supervisor was Newton Junqueira Franco who introduced me to the company and briefed me about the activities. He is an experienced individual who has worked at the company for a long time. Being a safety management student, my activities at the factory during the internship period focused on the safety issues around the company. Throughout the internship, attention was given to the safety issues that relate to the various activities carried out at the factory.  Ã‚  

Jinikin Jeans Human Resource Analysis and Strategies Essay

Jinikin Jeans Human Resource Analysis and Strategies - Essay Example By Jinkin Jeans beginning to alter the way in which they approach the structures within the company, there will be the ability to create a different set of return with the company while moving toward increased growth within the corporation. Analysis of People Management The main problem with Jinkin Jeans is noted first through the outcome of the performance that is a part of the company. The human resource management which occurs in a business directly reflects how the external environment responds and what is required for improvement by those which are functioning within a corporation. To alter this, there is the need to analyze the performance of the external environment first then to link this back to the way in which the human resources are functioning within the company (Paul, 2003). For Jinkin Jeans, this is noted with the external performance. There is difficulty in keeping up with the latest trends and fast pace of fashion that is required for the environment. More important, there are continuous complaints from customers and the inability to deliver the right products to those who are interested in the jeans. These are causing for lower performance and for competitors to move ahead of the jean company. The problem links to the management of those working for the company, knowledge of the vision of the corporation and the way in which the different development of jeans is being handled, both in terms of outsourcing the jeans and within the main corporation. The problem which is associated with the human management in Jinkin Jeans is furthered by not having the right individuals toward the tasks as well as carrying a loss of vision toward the requirements with the business. For Jinkin Jeans to remain as a part of the competition there needs to be an approach of having the latest fashion trends, creating accuracy with all products offered and to ensure that there is mainstream developments from all employees. More important, the leaders and those developi ng the products need to have a competent understanding of the tasks to be carried forward within the corporation to expand the market. It is noted that there is a direct relationship between total quality management and operational performance. Total quality management consists of first understanding the vision and values of the company then expanding this into an understanding of the relationships which come from the supply chain to the products and to the external environment. The operations then need to begin reflecting the external environment by the right human resources and the implementation of different tasks per person (Samson, Terziovski, 1999). The third problem which is a part of Jinkin Jeans is based on the outsourcing and lack of staff that is linked to both the outsourcing and the external environment. Currently, there is no marketing manager that is in place. It is also noted that the two owners continue to micromanage the different products without looking at specif ic needs within the corporation. The values with outsourcing and the communication processes don’t have any trained individuals which are working for the corporation and are unable to provide relevant processes that are a part of the corporation. This is combined with a lack of understanding of where the human resource management should implement leadership skills and what the main focus

Labor Economics Research Paper Example | Topics and Well Written Essays - 750 words

Labor Economics - Research Paper Example No matter how effective the human resource managers are in the selection and recruitment process, it appears that they still have to invest in employee training to optimize employee productivity. The essence of this article is to carry out an analysis of the two sources of employee knowledge and to provide a fact-based reaction on the same. Employee training refers to the provision of extra education to employees after the recruitment process as a way of enhancing their productivity by equipping them with knowledge that is relevant to the organizational activities. On the other hand, on-school training refers to the kind of knowledge that potential employees gain in school depending on the subjects and the topics they pursue in part of their career specialization. Most economists have failed to reach a concession on which of the two is more effective or which would be more beneficial to the organization in terms of profit turnover. Dostie (2008) is one of the researchers who have eng aged in an empirical research to investigate the effectiveness of the two sources of employee knowledge. The findings of her research indicate that there is a particular advantage in obtaining employees with proper school training rather than investing on on-job-training. It is indisputable to appreciate that each of the two types of training has its pros and cons and as it seems both are important to the firm. In supporting school training, Dostie (2008) points out that the subjects provided in school are optimized and are best suited for diversified for job opportunities. Consequently, employees will have a good background that will enhance their productivity while in the employment sector. In addition, employees who have adequate training will require little adapting to various work environments much quicker and hence reach the expected production rate almost after they are assimilated in the company. However, the major weakness in school trained employees is that they have littl e diversified knowledge while companies have specific operational activities that may be unique from one organization to the other. In short, although school training outputs an effective labor force, they may have shortfalls in terms of specialization and work orientation. On the other hand, the on-job-training is efficient in orienting new employees to the specific tasks that they are supposed to undertake in an organization. The strength of worker training lies in its ability to model the employees to fit their job description more efficiently and quickly whose cumulative effect is to improve their productivity. However, Dostie (2008) points out that employee training consume a lot of company capital that cannot be recovered by the impact of the process on employee productivity. From this point of view, on-job-training may have a negative impact on the turnover value of the company, which is contrary to the company’s aim of effecting this strategy (Goux & Maurin 12). In es sence, employee productivity can only be measured from their net contribution to the revenue turnover of the firm at the end of the fiscal year rather than their gross production rate. The main goal of any organization is to achieve maximum profits by optimizing employee productivity and minimizing the expenditure in terms of either salary or other priced business operations.

Child needs in Mental Health Research Paper Example | Topics and Well Written Essays - 750 words

Child needs in Mental Health - Research Paper Example One of these alternative methods that the article proposes is the person-centered or nurture approach to child mental health. Such a practical and empathic method of dealing with the actual experience of the child and his/her loved ones completely conflicts with the alleged psychoeducational model, which recognizes a biological explanation for mental distress, like schizophrenia. The article explained that in spite more than decades of continued criticism, the mental health nursing approach continues to rule the diagnosis and treatment of mental health illnesses. Even though initially related with a particular school of thought, the mental health model and, currently, the biopsychosocial approach and other psychosocial perspectives are all employed by different academic fields and expertise in their attempts to determine what has to be done for the sake of care, therapy, and medication. It is not unexpected that a particular nursing framework for mental health and psychiatric care di d not surface, or that theories of nursing have been quite poorly viewed by nurses themselves. Dissimilar from medicine and academic fields based on the social sciences, such as social work and medical psychology, nursing has traditionally been perceived as an intellectual minority, with very few empirical findings and negligible literature. Customarily, nurses have been relegated to a supporting role in the clinical field. In spite of two centuries of attempt to institutionalize an independent presence and a unique idea of the importance of nursing, nursing still seems to be preoccupied by the visions of the past. Because the general paradigm of mental health care keeps on involving the recognition of a clinical diagnosis and the operation of certain clinical interventions, the importance of any unique paradigm of nursing has been severely questioned. Analysis The article is quite descriptive and largely a review of related literature. In a way, the article has elaborated and justi fied the importance of person-centered approach to child mental health nursing, as well as the importance of alternative models, by mentioning credible scholars in the field. However, the article has some weaknesses. Even though nursing has an established relationship with the notion of caring through interpersonal attachments, ever more this has been dominated by claims for ‘evidence’ of their importance within an empirical scholarship framework. The article failed to provide some empirical justifications for its argument. Nevertheless, as some scholars argued, the dynamic mechanisms in nursing and the mental health patients, experiencing and dealing with a mental disorder, can eventually bring about healing, and are encountered per se by individuals under nursing care. The article argues that nurses have to build a certain rapport or attachment to the children in their care in order for them to unravel the experience of mental health disorder and wellbeing. Even thoug h health care is turning out to be apathetic and technologically, large numbers of mentally ill children and their families are demanding for care and medication to reconfirm the bonds between themselves and their healthcare providers. Within this point of view the

Study on Brady Udall Essay Example | Topics and Well Written Essays - 1000 words

Study on Brady Udall - Essay Example The thesis statement of this paper is that in his book, Letting Loose the Hounds, Brady Udall provides his characters an opportunity at hope to support his claim that dealing with the themes of sadness, despair and darkness alone cannot make a book candid and real.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Jerry, the protagonist and the narrator of Midnight Raid, is a representative of those people who are dealing with the pain of lost love. "Midnight Raid", perhaps the widely acclaimed story of Udall which is also the first story in this book, reflects the themes of darkness and confusion in the beginning itself. Through the simple, crispy and witty narration by Jerry we come to know that Jerry, drunk, is at the backyard of his â€Å"ex-wife Amy and her new husband Howard† (Udall) at Scottsdale, Arizona, to see his â€Å"seven-year-old son, Tate† and to gift him a goat â€Å"without Amy or Howard finding out about it† (Udall). Here, Jerry, who lost his son in the legal battle to his ex-wife Amy, has come to meet him. Though Jerry is aware about the negative consequences of his action, he deliberately puts in an effort to see his son and communicate his love. Though he had a troubled relation with Amy he was a loving father to Tate.  Ã‚   Hence, Jerry though convinces himself that his relation with Amy ended due to the indiscretions and betrayals  Ã‚   from both sides and that Howard is Amy’s new Husband, he fails to convince the father in him. Jerry, at the moment, is fragmented and is heartbroken.     Ã‚  Ã‚  Ã‚  Ã‚   Midnight Raid is essentially a tragic story which has been tamed well to make it candid and real.   Jerry as well as other characters portrayed in Udall’s stories is found to be constantly dealing with the confusion whether to accept or to fight their sad circumstances. They are stuck in the battle of wills and are constantly being torn apart between ‘letting go’ and ‘wanting to let go’. In t he case of Jerry, we can see that he is confused and worried about his wife who "left [him] to marry this liver-spotted senior citizen with dentures and an artificial leg". He consoles himself at the thought that Howard is rich enough to provide financial security to Amy. His mind is "completely scraped out from the inside" when he finally left his loved ones with Howard.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Udall by making Jerry the protagonist of Midnight Raid is purposefully interweaving humor in to the dark rather unpleasant story. Jerry, the narrator and the protagonist of Midnight Raid, was introduced by Udall as a six-foot-three Apache Indian carrying a goat into his ex-wife's back yard in the middle of the night. Udall bestows Jerry with comic sense that does not get stained even at the face of his desperation, which is evident from many of the passages of the story.   An instance for this is when Jerry, while narrating the â€Å"end of relationship story" states that his â€Å"divor ce was an honest, smash-mouth affair† (Udall).   Udall, in an interview by Robert Birnbaum, regarding the presence of comic in his stories, commented that "a book can't just be all darkness, all dark notes...I owe my characters some opportunity at hope or redemption. It's not going to be the redemption that the reader expects...I respect my characters...I can't just hurt them and kill them just for my purposes...It would be too much for me to do

Defining philosophy Essay Example | Topics and Well Written Essays - 750 words

Defining philosophy - Essay Example Philosophy is divided into sub fields since it is very wide and this depends on the sub-field an individual is interested in, for example an individual can study on epistemology, logic, metaphysics and ethics among other sub-fields. A sub-field of epistemology is scope of knowledge such as relationship between the truth and beliefs of certain community or group and how the philosopher can justify one theory depending on how the community or the group perceives it. Skepticism is highly valued in philosophy since it questions the possibility of justifying the truth and still regress the argument, meaning that one must support the argument with another justification. Munchhausen Trilemma perceive the study as a chain of infinitism where the chain of justification can go on forever, the next chain is foundationalism where this chain relies on basic beliefs of individual and lastly is coherentism where the chain keeps on moving in circular manner and the chain has its own chain of justifi cation (Munchhausen 56). The question of epistemology differ from scientific facts since according to scientist that knowledge is true belief that has been given account of by individual, and states that if something is actually known then categorically it is not false. Another question on philosophy according to Thomas berry is the universe being a communication of subjects and not a collection of objects. The foundation seeks to carry out great work of flourishing of the earth community; the theory promotes and distributes ideas on the great work, evening thoughts, the sacred universe, the Christian future and the fate of the earth. Thomas berry perceives the universe as a self-referential reality in the phenomenal world. Thomas terms the universe as text without context. The universe is seen as a story to many and the significance of the story is known, and still the universe story is quintessence of reality. Philosophers and scientist do perceive the story that

How Cell Phones and Other Inventions Affected the American Family Essay Example for Free

How Cell Phones and Other Inventions Affected the American Family Essay How Cell Phones and other inventions affect the American family There are many new inventions that have helped to advance our society and had an affect on the American family. Since the invention of the cell phone people no longer have to rely on payphones, mail, or even traveling. Email has made it easier for people to send mail faster. Instead of writing or typing out a letter and waiting for the post to send it, now you just hop on your computer type it out, send it, and a few seconds later it has been delivered. Entertainment has also made an impact on the American family. Entertainment has become more accessible over time and at this point you don’t even have to leave your house to order a new movie On Demand or buy a new song or even a whole CD. The cause of cellphones, email, and advanced entertainment has a great effect on the American family by helping them become more efficient. The cell phone has become so depended on; most people can’t leave the house without them. They help you become more accessible to other people and more recently have more features than just calling. Texting also makes it easy to send quick messages to people if you don’t have time to have a conversation on the phone. For instance, if you are in a loud place, like a concert or a quiet place where you don’t want to draw attention to yourself, like a church service. They also have other features like games, and music. You can buy games and music right from your phone; you can even access the internet straight from your phone. These new parts of the cell phone help the American family to become more efficient and get in communication with other people faster. Email has become more and more popular since it was invented. Now that just about everyone has an email it is not necessary to mail as many cards or letters anymore. Since the postal system takes so much time most people prefer email simply because their information gets there faster and more efficiently. Adults can send emails to their work and co-workers, which allows them to work from home without even missing a meeting. They can email all of their paper work and they can call into meetings now. Even kids/students can take advantage of this by send emails to their teachers with their school work attached if they are sick or just have late work. The American family has been affected in a very positive way by using these new inventions. Entertainment has also taken a turn into a new direction. There are so many new ways to keep yourself entertained without even leaving your house. For example, already mentioned the cell phone has games and music installed into it that gives you the opportunity to buy new things to keep yourself entertained. Then there is also the television that you can watch movies on or shows that you like. There is even programs like On Demand where you can access it right through your TV and buy a new movie for about five bucks and watch it without even having to leave your couch. The way that entertainment has expanded has had such an impact on the American family. This might not be as positive as the speeded up communication devices since this might cause you to be more inefficient and lay around all day. However, when these entertainment devices are used appropriately you can get a good use out of them without letting them consume all of your time. The way that these new inventions have affected the American family is mostly positive, with very little negative effects. Since these inventions, there has been a more efficient way of communication through cell phones and email, which helps work get done faster. The cell phone has diminished the need to have filthy pay phones all over and email has crushed the need to send many things through the postal office, which isn’t as speedy and efficient as email. With all of these new ways of speeding up work, that leaves us with more time to ourselves, and so we got new ways to entertain ourselves without having to leave the house after a long stressful day at work. Over all the cause of the inventions of things like cell phones email, and entertainment has a positive effect on the American family.

Tuberculosis: Prevention and Treatment

Tuberculosis: Prevention and Treatment Tuberculosis (TB) is an airborne infectious disease which is caused by strains of mycobacteria, mainly Mycobacterium tuberculosis1. There are roughly one third of the worlds population are infected with tuberculosis where nine millions of new cases reported annually2. Although tuberculosis can be prevented and treated, it continues to cause millions of deaths every year2. When infected individual coughs, sneezes or spits, M. tuberculosis is propelled into the air and infected those who breathed in the bacteria that existed in droplets of saliva3. Primarily, tuberculosis will affect the lungs, known as pulmonary tuberculosis3. It will also affect other parts of body, for instance lymph nodes, bones, brain and kidneys3. Once a person is infected with tuberculosis, there are basically three possible ways may occur. Firstly, the immune system plays a vital role and strong enough to kill the bacteria3. Secondly, immune system is not strong enough to fight off the bacteria but is able to b uild a defensive barrier against the bacteria3. Individuals who are latently infected with M. tuberculosis show asymptomatic where these bacteria lie dormant in the lungs and able to reactivate after years1. The disease is often reactivated in those who are immunocompromised or generally weakened. Lastly, the immune system fails to kill bacteria causing the bacteria to grow and spread towards other parts of body which is called active tuberculosis3. In the fight of tuberculosis, World Health Organisation (WHO) recommends universal Bacille Calmette-Guà ©rin (BCG) vaccination in the countries with high TB burdens4. BCG vaccine contains weakened form of M. tuberculosis which will induce human antibodies to fight against this type of bacteria. The efficacy of BCG vaccination can be ranging from 0% to 84%5. This may be due to the frequency of TB exposure and quality of vaccine used, leading to arguments on BCG vaccination efficacies4. One of the greatest arguments is that BCG vaccination causing positive reactions to tuberculin skin testing and hence interfere with the diagnosis of latent TB4. Existence of evidences showing the rates of efficacy also depends on geographical location, age at vaccination and form of TB further complicate the situation. Currently, TB chemotherapy is made up of combination of a list of first-line drugs isoniazid (INH), rifampicin (RIF), pyrazinamide (PZA) and ethambutol (EMB) 6. If the treatment fails d ue to bacterial drug resistance, or patient unable to tolerate, second-line drugs for instance para-aminosalicylate (PAS), fluoroquinolones, ethionamide and cycloserine are introduced6. These are considered as second line drugs generally either less potent with larger doses regimen or more toxic with serious side effects6. Tuberculosis is presently treated in two phases, namely initial phase and continuous phase7. In initial phase, the patient will be treated with concurrent use of four first line drugs, with the aim to eradicate or control bacteria population to replicate in rapid motion and also avoid the emergence of bacteria resistance7. The treatment choices available for initial treatment include isoniazid, rifampicin, pyrazinamide and ethambutol7. Streptomycin is used rarely but can be used in patients who infected with bacteria that are resistant to isoniazid before the therapy is commenced7. The duration for initial phase is 2 months whereas the continuous phase takes 4 months7. During the four months of continuous phase, patients are treated with isoniazid and rifampicin at same doses7. Most of the TB treatment is supervised where drug administration needs to be fully supervised by healthcare professions since lengthy duration of treatment causing incompliance in patients7. These patients who are unlikely to be compliance will be given the drugs three times a week until the course is completed while patients who able to comply with the treatment will not be supervised7. Despite the chemotherapy treatment and BCG vaccine, TB remains as a significant infectious disease due to increasing emergence of drug resistant TB and co-infection with Human Immunodeficiency Virus (HIV) 6. Since the host defense in HIV patients is suppressed, they are more susceptible to TB infections. Moreover, drug- drug interactions between antiviral therapy and anti-TB also causing complications in treating co-infected patients6. Drug resistant TB has evolved mainly because of improper treatment or incompliance in patients who stop taking their medications before the bacteria is being fully eradicated since the duration of treatment is lengthy which takes 6-9 months8, 9. The mechanism involved includes chromosomal mutations in genes that responsible for drug targets encoding9. When there is a sequential accumulation of mutations, multi-drug resistant tuberculosis (MDR-TB) emerges where the M. tuberculosis strains will resistant to two of the most commonly used drugs, Isoniazid and Rifampicin9. Patients with MDR-TB are then relying on the second-line drug classes, fluoroquinolones and the three injectable agents namely amikacin, capreomycin, and kanamycin10, 11. The chances to cure would dramatically be reduced for patients who infected with extensively drug-resistant tuberculosis (XDR-TB), a situation where the isolated strains are resistant against any one of fluoroquinolones and at least one of three injectable drugs6. In order to combat with the MDR-TB or XDR-TB and optimize the tuberculosis drug regimen, it is crucial to understand the mechanism of action of current using first-line drugs and how resistance is developed against these drugs. Isoniazid (INH) or isonicotinic acid hydrazide is discovered in 1952, a bactericidal agent which active against organism of the genus Mycobacterium, especially M. tuberculosis, M. bovis and M. kansassi6, 12. In vivo, INH has shown to be bactericidal in culture over the first 48 hours which become bacteriostatic after this particular time frame12. This indicates that INH is bacteriostatic for slow replicating bacilli but is bactericidal against rapidly dividing mycobacterium. The minimal tuberculostatic concentration is 0.025 to 0.05ug/ml13. INH is a prodrug that needs to be activated by catalaseperoxide hemoporotein, KatG before acts by inhibiting mycolic acid synthesis and cell wall disruption in susceptible mycobacterium13, 14. This inhibitory action is only targeted to mycobacteria since other bacteria do not contain mycolic acid in the cell wall13. INH acts by inhibit enoyl acyl carrier protein (ACP) reductase, InhA, and a beta-ketoacyl-ACP synthase, KasA that are crucial in fatt y acid synthesis system for mycolic acid15. Resistance to INH is believed due to mutations in gene encoding catalaseperoxidase katG or InhA or lacking KatG 9, 14. Isoniazid is metabolised in the liver, mainly by acetylation and dehydrazination where slow acetylator may experience higher concentration leads to potential toxicity before excreted in the urine within 24 hours13. Rifampicin (RIF), discovered in 1963, is a lipophilic semisynthetic derivative of rifamycin antibiotic which is produced by the fermentation of a strain of Amycolatopsis mediterranei6, 9, 16. RIF has bactericidal activities against a broad spectrum of microorganisms including gram-positive and gram-negative. RIF will inhibit the action of DNA-dependent RNA polymerase of mycobacteria that is encoded by rpoB through formation of a stable drug-enzyme complex9. This will suppress the initiation chain formation in RNA synthesis and hence prohibit protein synthesis in M. tuberculosis9. Development of resistance to RIF is mostly due to mutation in 81 base pair region of rpoB gene thus facilitate a straightforward approach to detect MDR-TB since 85-90% RIF-resistant strains are also resistant to INH9. RIF produces peak plasma concentration of 7ug/mL in 2 to 4 hours after ingestion of 600mg17. It also distributed well to most of the body tissues and fluids, including cerebrospinal fluid since it is lipophilic17. Following absorption from the gastrointestinal tract, RIF is eliminated rapidly in the bile with fewer amounts excreted through urine17. Pyrazinamde (PZA) is discovered in 1954 and it produces excellent sterility effects against semidormant tubercle bacilli at slightly acidic pH6, 9. The antimicrobial activity of PZA is through interference with mycolic acid synthesis in M. tuberculosis by pyrazinoic acid, an active moiety of PZA9. Conversion of PZA to pyrazinoic acid is mediated by pyrazinamidase enzyme that is encoded by pncA gene in M. tuberculosis, thus indicating that these bacilli are sensitive to PZA9. Resistance against PZA evolved when mutation occur at pncA gene that is responsible for pyrazinamidase, hence affecting the activity of this enzyme9. PZA is well absorbed from gastrointestinal tract and is widely distributed to most tissues and fluid too17. The oral administration of 500 mg PZA produces plasma concentrations of 9-12ug/ml after two hours and 7ug/ml after 8 hours17. PZA is metabolized in liver whereas the metabolites are excreted through renal glomerular filtration17. Ethambutol (EMB) is discovered in 1962, acts as bacteriostatic agent and is active against undergoing cell division6, 18. EMB primarily targets on impairment of cell wall polymerization by inhibits arabinosy transferase, a vital enzyme responsible for mycobacteria cell wall biosynthesis9, 18. Since arabinosy transferase enzyme is encoded by embC-embA-embB genes, resistance against EMB evolved is believed due to mutation of these genes9. EMB is currently used as one of the first-line treatment for tuberculosis mainly because of its synergistic effect with other front-line drugs and its low toxicity property18. There is roughly 75-80% of an oral dose of EMB is rapidly absorbed in gastrointestinal tract with absorption unaffected when administered with foods19. In addition, EMB is distributed widely to body tissues and fluid, including cerebrospinal fluid before being metabolized in the liver and excreted in urine19. Streptomycin (SM) is an aminoglycoside antibiotic, used as first line treatment for TB when it first discovered in 19441, 6. Streptomycin is isolated from the bacteria Streptomyces griseus and its antimicrobial effects against M. tuberculosis is highly effective when use in combination with other first line agents20. However, SM is no longer considered as first line treatment as resistance against it has developed rapidly1. The optimum pH for SM is at pH8 where its bacteriostatic activity will reduce with increasingly acidic environment20. SM acts by binding tightly to A site of 16S ribosomal RNA subunit, interferes with mRNA translation, causing faulty protein being produced1, 9. Resistant emergence when the mutation occurs at gene rpsL and rrs that encoded for 16S and S12 ribosomal protein1, 9. Upon administration, SM is poorly absorbed from gastrointestinal tract and mostly administered parentally1. SM is mostly excreted in urine and patients with low renal profile might experienc e toxicity such as neurotoxic reactions1. When the first line treatment is no longer suitable for patients or patients develop multi-drug resistance TB, second line drugs will then be introduced in combating the TB. Second line drugs that are mostly used include Ethionamide (ETH), Cycloserine (CS), Para-Aminosalicylic Acid (PAS) and Fluoroquinolones (FQ). ETH has been in use since 1960s, is a structural analogue of INH and it targets at inhibition of mycolic acid biosynthesis in tubercle bacilli9, 21. INH however is much more potent than ETH since the minimal inhibitory concentration for ETH is 0.5-5.0ug/mL21. Resistance evolved due to mutation at gene InhA and ethA which encode for oxygenase enzyme in activation of ETH 9. In vitro, CS has inhibitory effect on M. tuberculosis at 5-200ug/mL and there is no cross resistance occurred between CS and other drugs13. CS acts by interfereing the biosynthesis of bacterial cell wall13. CS is well absorbed in gastrointestinal tract and also widely distributed to body tissues and fluid including cerebrospinal fluid13. PAS was first introduced as first line drug but being replaced by Ethambutol in 1960s1. It acts bacteriostatically with possessing inhibitory effect at concentration less than 1mg/ml by interfere with folic acid metabolism in bacteria1. PAS is readily absorbed from gastrointestinal tract and distributed well throughout the body. Approximately 80% of the drugs will be excreted via kidney after being metabolized to acetylated form1. Moxifloxacin and Gatifloxacin are both been synthesized and evaluated as excellent bactericidal agents through inhibiting DNA gyrase, an ATP-dependent enzymes topoisomerase II which is responsible in bacteria DNA transcription9. DNA gyrase is consisted of two subunits that is arranged in a complex, is encoded by two different genes, gyrA and gyrB where mutations at gyrA will normally cause bacteria resistance to these new generation of flouroquinolones9. Due to the increasing incidence of multidrug resistance TB, it is highly desirable to develop new drugs that are not only potent and effective against current resistant strains of M. tuberculosis but also possess shorter treatment duration since most of the incompliance of patients is brought up by lengthy TB treatment. Most of the mechanisms of action of current treatments are involved in interfering the bacterial DNA synthesis, protein and mycolic cell wall biosynthesis. The enzymes that participate in these pathways could also be the target of newly designed drugs such as TMC207, one of the new drugs which are currently under investigations and clinical trials. TMC207 is a member of diarylquinoline class of compound which target at adenosine triphosphate (ATP) synthase by binding to subunit C of the synthase, blocking the energy pathway of mycobacteria22, 23. In vitro, TMC207 not only possesses ability to inhibit both drug sensitive and resistant M. tuberculosis isolates, but also able to sterilize the patient through killing the dormant bacilli bactericidally22. TMC207 showed a minimum inhibitory concentration of 0.03ug/mL against M. tuberculosis, suggesting a more potent agent compared to current first- line treatments such as isoniazid and rifampicin23. Apart from that, its synergistic effect with pyrazinamide could promise as effective drug combination for sterilizing the patients against TB22. A phase I clinical trials which involved short terms administration of TMC207 in healthy individuals showing no adverse effects and the subjects are well tolerated with it23. However, it is essential to investigate the selectivity of TMC207 again st mammalian ATP synthase with longer periods to ensure the patients safety when administered with TMC207. Thiacetazone (TAC) is widely used as second line anti-TB agent against multiresistant tuberculosis at present24. TAC acts by interferes the biosynthesis pathway of mycolic acid in tubercle bacilli24. The fact that M. tuberculosis has been difficult to eradicate and remains persistent is due to its cell wall that composed of mycolic acid which is resistant against chemical injury, dehydration and also has low permeability to antibiotics24. Mycolic acid contains cyclopropane rings that is activated through cyclopropane mycolic acid synthase (CMASs), has a significant contribution to tuberculosis24. By inhibiting the cyclopropanation, the cell wall biosynthesis will then be interrupted, introducing the bactericidal effects24. The aim of this research is to synthesis and evaluates the analogues of Thiacetazone which might be potential anti tuberculosis agents. The analogues will be tested against different strains of mycobacteria in lab. The target actions of these analogues will also be identified based on the structure of the analogues. The above analogue is synthesized when a benzylaldehyde reacts with a primary amine. This is a condensation process and an imine is produced. The changes at position R1 to R3 with different electron withdrawing groups are first planned to be evaluated. However, the plan is prohibited since the corresponding structures are either unavailable or too expensive that falling outside the budget. After revised on the previous analogues that were discovered and their respective MIC values obtained from lab, the structures of new analogues that are going to be evaluated are finally sorted out. The R1 to R3 positions would be replaced by either a -chloro or a -methoxy with R8 position would either be an amine, a methyl or a benzene ring. A chloro is used at position R1 to R3 since it is electron withdrawing, big and lipophilic molecule whereas the methoxy group is electron donating, small and quite lipophilic. For R8 position, an amine is selected because it is electron withdrawing and small. A methyl is also selected since it is quite lipophilic, small and electron donating. On the other hand, benzene ring which is highly lipophilic, neither electron donating nor withdrawing group might have a different effect on the analogue synthesized.

Thiacetazone, an Antitubercular Drug that Inhibits Cyclopropanation of Cell Wall Mycolic Acids in mycobacteria. PloS ONE, 2(12): e1343. Mycolic acids are a complex mixture of branched, long-chain fatty acids, representing key components of the highly hydrophobic mycobacterial cell wall. Pathogenic mycobacteria carry mycolic acid sub-types that contain cyclopropane rings. Double bonds at specific sites on mycolic acid precursors are modified by the action of cyclopropane mycolic acid synthases (CMASs). The latter belong to a family of S-adenosyl-methionine-dependent methyl transferases, of which several have been well studied in Mycobacterium tuberculosis, namely, MmaA1 through A4, PcaA and CmaA2. Cyclopropanated mycolic acids are key factors participating in cell envelope permeability, host immunomodulation and persistence of M. tuberculosis. While several antitubercular agents inhibit mycolic acid synthesis, to date, the CMASs have not been shown to be drug targets. We have employed various complementary approaches to show that the antitubercular drug, thiacetazone (TAC), and its chemical analogues, inhibit mycolic acid cyclopropanation. Dramatic changes in the content and ratio of mycolic acids in the vaccine strain Mycobacterium bovis BCG, as well as in the related pathogenic species Mycobacterium marinum were observed after treatment with the drugs. Combination of thin layer chromatography, mass spectrometry and Nuclear Magnetic Resonance (NMR) analyses of mycolic acids purified from drug-treated mycobacteria showed a significant loss of cyclopropanation in both the ?- and oxygenated mycolate sub-types. Additionally, High-Resolution Magic Angle Spinning (HR-MAS) NMR analyses on whole cells was used to detect cell wall-associated mycolates and to quantify the cyclopropanation status of the cell envelope. Further, overexpression of cmaA2, mmaA2 or pcaA in mycobacteria partially reversed the effects of TAC and its analogue on mycolic acid cyclop ropanation, suggesting that the drugs act directly on CMASs. This is a first report on the mechanism of action of TAC, demonstrating the CMASs as its cellular targets in mycobacteria. The implications of this study may be important for the design of alternative strategies for tuberculosis treatment.

Antigone, by Sophocles | Analysis

Antigone, by Sophocles | Analysis Antigone is a tragedy book written by Sophocles with a protagonist named Antigone who is very determined towards her only goal of burying her dead brother Polynices as mentioned in the play. At the other side full of contrast and with a different point of view is the book House of the spirits. House of spirits is a magnificent marathon of the Trueba family including their ambitions and their love for each other. In order to enable the readers continue reading to the very end of the whole book, their attention needs to be captured and allow whatever they are reading to be understood and interesting. And for all this to be done, the reader should be involved in the story emotionally ensuring that the reader is fully in the book and not to be fully lost in the story. This is where the writers take the advantage of using emotions which makes a reader feel closer to certain characters and understand each and every thing the writer is trying to portray. Emotions!! We all have different definitions and ways of what it is. According to the dictionary, emotion is a mental state that arises spontaneously rather than through conscious effort and is often accompanied by physiological changes. Therefore, in simpler terms, emotion is the language of a persons internal state of being. There are different types of emotions which may include joy, love, sad etc. There are various emotions present in both the books Antigone and House of the Spirits. The emotion portrayed most of the times in each of the books is Love. As a reader, we repeatedly see the emotion of love in House of the Spirits between Blanca and Pedro, Rosa and Esteban. The emotion of love is also present in Antigone between Antigone and Haemon. There is also brother-sister love presented in the play through Antigone and the dead brother Polynices. The other emotion present in both the books is emotion of hate. According to the dictionary, hate is defined as the feeling for extreme aversion or extreme hostility towards something or someone. The emotion of hate in Antigone is brought about through King Creon towards the protagonist Antigone. Throughout the play, we see King Creons hatred for the protagonist Antigone in one way or the other. Creon expresses his disgust for Antigone when she goes against him and buries her brother and argues back that she was right in doing what she had done and wasnt at all guilty, oh but I hate it even more when a traitor, caught red-handed tries to glorify his crimes.Such a harsh usage of the word hate emphasizes on how much he hates his own niece. Emotion of hate is also present in the novel House of the spirits. We see hatred from Ferula towards Esteban when he is chasing her from his house. I set my curse on you, Esteban; you will always be alone! Your body and soul will shrivel up and youll die like a dog. Reading this quote explains us how much other people are hurt through Estebans hate. There is also an emotion of pity present in the play Antigone and the novel house of spirits. This is represented at the beginning of the play through a conversation between Antigone and her sister Ismene. During the conversation, we get to know that the two sisters lost their father in a certain battle and their brothers at the same time and then we as the readers come to know that one of the brothers, Polynices, has been left unburied. And this makes us feel pity for the two sisters. There is an emotion of desire in both House of spirits and Antigone. Desire is a sense of jones within the mind, when the soul has a hungry requirement for a specific item. And in Antigone, we see this through King Creon desiring power. Through the play we see King Creons desire for power being expressed straightly through his words, That these two sisters were aiming at my throne. We see King Creon accusing the two sisters of trying to steal his power. And moreover his overwhelming desire made him think and believe that all the things happening are plans to gain his power. We experience the emotion of desire repeatedly in the novel house of the spirits through different characters. In the start, we feel Estebans desire to gain a better living standard to gain Rosa. Those were difficult times. I was about twenty-five then, but I felt as if I had only a little life left ahead of me to build my future and attain the position that I wanted. I worked like a beast and the few times I sat down to rest, not by choice but forced by the tedium of Sunday afternoons, I felt as if I were losing precious moments of my life: each idle minute meant another country away from Rosa. This clarifies that Esteban desired Rosa from his whole heart. After which we see his desire to rescue Alba from the government. There was also Blancas desire for Pedro Tercero and Esteban Garcias desire to be the heir of Esteban Trueba. Guilt is a powerful emotion because it makes people act differently than they normally act. There is also an emotion of guilt which is involved in both the play and the novel. In house of spirits, we all see that Blanca was forced to marry Jean de Satigny because she was pregnant and had no other option for her forbidden pregnancy and Jean de Satigny had no refusal towards this relationship because he had always wanted to marry a rich, young, beautiful South American heiress. And he knows that accepting this grand offer by Esteban Trueba would enable his dream come true and there was nothing for him to lose and just to gain as he didnt needed any personal fulfillment from Blanca and accepting the offer would certainly lead to advancement in his status. At the other side, emotion of guilt in Antigone is presented in scene 2 when Antigone is caught but she does not believe she has broken a true law. Creon also arrests Ismene, who tries to proclaim her guilt, but Antigone denies her and Antigone is sentenced to death. This is a bit where we experience the emotion of guilt. Emotions play a huge role towards seeking the readers attention. Having emotions in a certain novel or play attracts the readers attention and involves them into the story emotionally and to understand what the writer was trying to portray and understand the character traits by being in their position emotionally. Emotions used both in House of the spirits and Antigone had a grand effect on the readers both mentally and physically. The readers were able to understand each situation very well through the emotions brought about. For reference, in House of spirits, when we read on how Blanca used to escape at nights to meet Pedro, we extrapolate that they love each other basing on how they used to meet. We feel sad for the two sisters in Antigone when we read that they lost their father and both the brothers at the same time and one of them is still left unburied. Emotions enable to bring out the themes of the novel and the play hence allowing more understanding from the readers side.

The Amazon Rainforest is the largest rainforest on Earth. Covering an area of five and a half million square kilometres, it is composed of a diversity of ecosystems forming the Amazon Basin that drains into the Amazon River. Although deforestation can occur naturally through events such as droughts that cause many trees to die, human intervention is the most prolific cause. Rising population levels within the Amazon basin have contributed to an escalation in the deforestation of the rainforest. This is due to urbanisation and an increased demand for timber to be used in building and commercial production of items such as paper, furniture and palm oil. Deforestation has a negative impact on the local environment of the Amazon. As the forest is removed the soil loses its anchor point and it is steadily eroded, most notably during the wet season. This contributes to the instability of the remaining trees and pollution of local waterways. The physical removal of the trees removes the habitats and food sources of many animal and insect species that live there. In turn this causes a reduction in diversity of the remaining species and a disruption in the ecosystem of the rainforest. (Lean and Warrilow 1989, 411-413). A study was completed which involved simulating the deforestation of the Amazon tropical rainforest, and replacing it with pastural grazing lands. The results showed a climactic variation of a weakened hydrological cycle, with less precipitation and evaporation and an increase in surface temperature. (Lean and Warrilow 1989, 411-413). The importance of the Amazon rainforest in global environmental issues is largely due to its immense size. Terrestrial plants absorb 25% of the atmospheric carbon dioxide during photosynthesis. Carbon dioxide emissions are a by-product of natural processes and human interventions such as burning fossil fuels. Through a process known as sequestering the plants store carbon in their wood and soil. The massive scale of the Amazon and its sequestering capabilities leads to it being referred to as a carbon sink: able to slow the accumulation of carbon dioxide in the atmosphere, and therefore its contribution to global warming. It can only be classified as this if it absorbs more carbon dioxide than it releases. By 2015 the atmospheric concentration of carbon dioxide was 400 parts per million, this was an increase from the 290 parts per million level recorded at the turn of the century. (Keenan, Trevor, Colin Prentice, Josep Canadell, Christopher Williams, Han Wang, Michael Raupach and James Collatz 2016.) The deforestation of the Amazon rainforest not only decreases the quantity of carbon able to be stored, it also causes a dramatic increase in the levels of carbon being released into the atmosphere by the dead trees. According to the Global Forest Resources Assessment, Main Report (2010), worldwide deforestation releases almost one billion tonnes of carbon into the atmosphere annually. Although measures are beginning to be implemented to reduce the levels of carbon released into the atmosphere, more needs to be done to prevent levels rising to 600 parts per million-a level the world could reach as early as 2050[m1] (Daniel Grossman 2016, 635). Due to the sheer size of the Amazon rainforest, alterations to its local environment can be felt in other parts of the world. David Werth and Roni Avissar (2002) point out that deforestation in the Amazon has a measurable effect. It can cause a reduction in levels of precipitation and evapotranspiration as well as the formation of clouds. This impact could be felt in several areas around the world, that displayed an increase in the length of their dry seasons. Restoration of the tropical rainforest areas of extensive deforestation could be greatly inhibited due to this increase in temperature and dryness. (Shukra, Nobre and Sellers 1990, 1322-1325). though the numbers are not as high as the ones recorded in the previous decade. Deforestation is the second largest anthropogenic (human-caused) source of carbon dioxide to the atmosphere. Brazil and Indonesia, which had the highest net loss of forest in the 1990s, have significantly reduced their rate of loss, according plays a crucial role in keeping carbon out of our atmosphere, as it naturally absorbs about 28% of the atmospheric carbon emitted by the burning of fossil fuels elsewhere According to Michael Daley, associate professor of environmental science at Lasell College in Newton, Massachusetts, the No. 1 problem caused by deforestation is the impact on the global carbon cycle. Gas molecules that absorb thermal infrared radiation are called greenhouse gases. If greenhouse gases are in large enough quantity, they can force climate change, according to Daley. While oxygen (O2) is the second most abundant gas in our atmosphere, it does not absorb thermal infrared radiation, as greenhouse gases do. Carbon dioxide (CO2) is the most prevalent greenhouse gas. In 2012, CO2 accounted for about 82 percent of all U.S. greenhouse gas, according to the Environmental Protection Agency (EPA). Trees can help, though. 300 billion tons of carbon, 40 times the annual greenhouse gas emissions from fossil fuels, is stored in trees, according to Greenpeace. [m1]

Graduation Speech: God Has a Plan for You -- Graduation Speech, Commen

In "Surprised By Joy," C.S. Lewis tells of a mistake that he had observed regarding joy or what he calls "thrills." Lewis realized that what he had first thought to be joy, was actually not joy at all because it began to fade away. He had assumed that he was seeking after the "thrill" itself. He says, "And there lies the deadly error. Only when your whole attention and desire are fixed on something else ... does the 'thrill' arise. It is a by-product. Its very existence presupposes that you desire not it but something other and outer." He realized that when he focused his attention on obtaining the "thrill" of joy, that he was actually focused on himself. True joy is not experienced when one desires joy itself, but when one has his eyes on something else. As believers, the "other and outer" that we have the opportunity to look to is God! God draws us to Himself, our soul responds to Him and in return, He fills our soul with joy. That is portrayed in the words of the Psalmist who says in Psalm 43:3-4, "O send our Your light and Your truth, Let them lead me; Let them bring me t...

Life with a Siberian Husky Essay example -- essays research papers

Life with a Siberian Husky I really had no idea what I was getting intowhen I decided to get a Siberian Husky for a pet. Don't get me wrong: Iwouldn't trade him for anything and I love him dearly, but this animal has hisown plan - his own agenda. The last three years of my life have been anawakening to the downright mischievous nature of these dogs. I've met other Husky owners and they all have the same stories of their dogs running away and possessing the trademark Husky stamina. They also tell of the little idiosyncrasies, such as their dogs "talking" and the way Huskies know when you're speaking about them when they are in the room. All of these owners are amazed at the Houdini-like capabilities these dogs have to help them escape any enclosure. I have a few entertaining stories of my own about my Husky, Khayman. First of all, he is the dog that everyone loves and no one wants to own. I can barely get anyone to watch him for more than ten minutes. It's not that Khayman is a mean animal--he isn't--he is just clever. Part of the reason everyone likes him is because of his looks, but mostly he's got a lot of personality. His bandit mask and two different colored eyes (blue and brown) get him attention, pats on the head, dog biscuits at the gas station, and royal treatment whenever anyone finds him on his escapades (which, mind you, have been many). His first escapades didn't take him far, mostly running down the street a few blocks after bum rushing the...

Great African Culture

The Great African culture is the result of the influences of the African kingdoms and city states which thrived and prospered between 1200 and 1500 CE. In addition to this, the forces of cultural diffusion as well as trade had influenced and changed these African civilizations.The ruling Kingdom of Songhai, due to the influence of the Arab culture and trading system, was replaced by the Mali. This new power in Western Africa influenced and expanded the ruling class, culture, society and its people.On the other hand, through extensive trade contacts, Islamic traditions and customs were brought to East Africa. Consequently, this had a huge influence on the culture and politics in Swahili city-states. On the other hand, the Great Zimbabwe was able to deter the influence of Islamic cultural diffusion and other cultures despite having trading contacts from the Middle East, India and China.This is due to the obstacles created by its natural geographic location. While Kongo in West Africa c ontinued to trade slaves, goods in return for weapons from the Portuguese merchants, ultimately leading to a change in religion (towards Christianity). In 1500, the power of several African societies was reduced because of the expansion of slave trading in the region.Generally, through trade, the African societies transact all the activities related to production and the reproduction of human life in its culture. Culture is consists of all that members of a society do. It is also passed on from one generation to another.Trade and development eventually must be understood or recognized as a cultural process, wherein culture is identified to encompass the social, economic, religious, political and other areas of social life and activity.In the African situation, conceivably greater than any other area of the world, culture as an incremental, as an inheritance and constructional basis of life and society, had a propensity to be forsaken in favor of unsystematic mimicry and cheap imitat ion of Western practices.The consequence of this is failure during most of the post-independence period to crucially or â€Å"significantly improve the quality of life of the majority of people in the continent† (Ukaga and Afoaku, 2005). Accordingly, modern Africa is still one of the poorest regions of the world regardless of its vast endowments of natural and human resources. ReferencesUkaga, O., & Afoaku, O. G. (2005).

Caribbean Slavery Essay

Slaves were flock captured in war, used to break up a debt, or make slaves as a means of punishment. The Spaniards in the Caribbean had little contain for African slaves in the early 1500s for miscellaneous reasons. The pact of Tordesillas, which was a line of product line drawn north to south, west of the Azores and blanket Verdes, stipulated that the areas west of the line belonged to the Spaniards and the east to the Portuguese. As a result of the treaty Africa was on Portugals side of the line, so in order for Spaniards to obtain African slaves they had to go through the Portuguese.During the period of the early 1500s the Treaty of Tordesillas resulted in the Portuguese being the commencement ceremony nation that the Spaniards granted an asiento. This was granted in 1515. These special licenses, asientos, only allowed a specific bod of slaves into a diverse number of countries and limited the need for African slaves. The comprise to ship slaves from West Africa to Port ugal and Spain and then to the Americas turn up prohibitive. There was easier access to Taino tire and it was redundant to spend extra money on importing slaves.Tainos were used to find and exploit the specie because they were familiar with the surroundings and thither were enough Tainos to mine the little gold the Spaniards had found. hold servants or white servants overly contributed to the need for only a little(a) number of African slaves in the 1500s. obligate servants (contracted exerciseers poor people from Europe) started to migrate to the Caribbean from Europe, as the Caribbean were advertised as having prospects of a parvenu life and jobs. Their contracts usually lasted four to cardinal years. The is dirts that were found in the Caribbean needed to be developed in order to soak up them suitable for living.The Spaniards offered property as an fillip to attract people who would develop the islands and settle there. This was how bound(p) servants were coaxed into migrating. Eventually however, the Amerindians and white servants were no longer a sufficient churn force. B. The Amerindians were non used to the working conditions and thence died. Also, mature World diseases such as measles, diphtheria, typhus, cholera, scarlet fever, chicken pox, yellow fever, whooping cough, smallpox, grippe and gonorrhea affected them while well-nigh died from depression.Indentured servants were unskilled in glossiness and unwilling to work. They were unaccustomed to the conditions of the Caribbean and succumbed to various bran-new World diseases such as syph and yellow fever. Africans worked harder, survived the conditions of the Caribbean better (similar conditions existed in Africa), knew how to mark equatorial plants, and were more(prenominal) resistant to Old World diseases. They were also less costly than hold servants and there was a more uniform supply of African slaves than indentured servants.The trade winds which blew from east t o west made coming to the Caribbean from Africa very easy. That is in analogy to traveling from Europe to the Caribbean which was demanding as the trade winds worked against sailing ships. Also ships had a longer distance to cover when they sailed to the Caribbean from Europe. African slaves were their masters property. Masters could do whatever they pleased with the African slaves as they paid for them and they were their property. Offspring produced by express slaves was also their masters property.This added to the reliableness of African slaves as there would incessantly be another generation to enslave. Indentured servants could soft escape as they had the uniform appearances, knew the culture and language and therefore could easily blend into the crowd and disappear with the inflow of people coming and leaving the Caribbean islands. Africans could not do this because of their colour and it would be difficult for them to escape. This added to the appeal of using African s laves. grove owners became greedy and no longer wanted to give or offer their net lands so as to attract indentured servants to come to the Caribbean. The plantation owners saw the Africans as a commodity therefore did not have to give any incentive to attract them because they were their property and enslaved to them. For these reasons the Africans were seen as a perfect source of labour. Increased work resulted in increased productivity, which increased the riches of the Spaniards. C. By the 1600s and 1700s African slaves became more familiar in the Caribbean.Amerindians had died out by the 1500s due to diseases, overwork and ill-treatment. Indentured servants had preoccupied fervour in coming to the Caribbean as it was costly to travel and the chances of surviving the tropical conditions were slim. Some ran away, breaking their contract, to become Buccaneers. The surrender in the number of available indentured servants and Tainos, and the growth of the colonies increased th e need for labour. scratch had become very popular and was in demand on the European market. The wealth that excoriation brought was recognized and more land as cultivated for sugar production. The sugar revolution had begun and the Dutch saw an chance to sell slaves in the Caribbean as there was a rise in labour needs. The Dutch were granted an asiento in 1667, by this time Dutch trading in African slaves became very popular. Additionally, slaves were severely mistreat and thus many died. The rapid death of slaves from the harsh conditions resulted in a constant need and this also added to the great address of African slavery in the tranquillity of the Caribbean in the 1600s and 1700s.
