Water Conservation Essay INTRODUCTION: Water is essential for life on earth. Water is needed for growing food, keeping ourselves clean, generating power, controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it. Water conservation: Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning, manufacturing, and agricultural irrigation. Fresh Water Availability: * Two thirds of the surface of the Earth covered with water, so you might be thinking why it is a problem. It is because most human uses require fresh water with about 97.5% of the water on the Earth, salt water it leaves only 2.5% to be fresh water. Furthermore, two thirds of it is made up of ice frozen in glaciers and polar ice caps. The remaining majority is groundwater with a very small fraction present above ground or in the air. * Access to safe drinking water has improved over the last decades in almost every part of the world, but approximately one billion people still lack access to safe water and over 2.5 billion lack accesses to adequate sanitation. There is a clear correlation between access to safe water and GDP per capita. * A recent report of 2009 suggests that by 2030, in some developing regions of the world, water demand will exceed supply by 50%. * Water plays an important role in the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. THE CRISIS: * 97 % of the Earths water is salt water? * The percentage of the worlds total water is available to drink is less than 1 %. * Water conservation refers to reducing the usage of water and recycling of waste water for different purposes like domestic usage, industries, agriculture etc. * Over the years rising populations, growing industrialization, and expanding agriculture have pushed up the demand for water. * Efforts have been made to collect water by building dams, reservoirs and digging wells; some countries have also tried to recycle and desalinate sea water. * Water conservation has become the need of the day. * The method of recharging ground water by harvesting rainwater is gaining importance in many cities. * Water conservation can be done through what you do, not by what you know. * In the forests, water seeps gently into the ground due to vegetation cover. This groundwater in turn feeds wells, lakes, and rivers. Protecting forests means protecting water catchments. In ancient India, people worshipped Nature and one of them was Water. AT A STAKE: The importance of protecting our water resource cannot be overstated. Regrettably, in countries like Canada that are blessed with an abundance of fresh water, there is continuous misuse and abuse of the resource: household toilets that use 20 liters per flush when 6 liters would do, and to industrial plants and municipalities that use water bodies as convenient sewers. About 70 percent of the earth’s surface is covered with water. Of that, only 0.3 percent is usable by humans. The remaining 99.7 percent is either unusable salt water or unavailable fresh water. And, most of the 0.3 percent is out of reach, locked up in icecaps and glaciers. Water is a commodity that is essential to life on this planet. Plants and animals need clean water to survive. Humans rely on finite supplies of freshwater to stay alive, without it people cannot live more than a few days. Almost everything we do uses water in some way. Unfortunately, all of earth inhabitants share 1 percent of all the water on earth. And with exploding human population growth, especially in poor countries, these finite supplies get quickly used up. The water we have now is all there will ever be. We cannot quickly produce more water. It can form on its own through the ecosystem but that takes centuries, whereas using up the earth’s water resources takes just a few seconds by turning on a tap. It is our responsibility to not only conserve water, but to make sure that it stays clean as well. According to the World Bank, as many as two billion people lack adequate sanitation facilities to protect them from water-borne disease, while a billion lack access to clean water altogether. â€Å"According to the United Nations, which has declared 2005-2015 the â€Å"Water for Life† decade, 95 percent of the world’s cities still dump raw sewage into their water supplies?† Thus it should come as no surprise to know th at 80 percent of all the health maladies in developing countries can be traced. Water wastage People waste water in their homes without even realizing it. We have become so accustomed to have a 24 hour supply of water to meet all of our needs from cooking, to cleaning, to drinking, that we sometimes forget that we do not have an infinite supply of water. Besides using renewable energy in the home to cut back on the use of electricity, we must also learn how to save our water supply. Here are a few tips on how to do so. †¢ The first thing you should do is check for leaks in taps, pipes, and dishwasher hoses which can cause over 2,000 liters of water per month to be wasted. Repairing any leaks will save you a ton of money and you will also be saving the environment. †¢ In the same way that you can buy renewable energy, you can also buy water efficient taps that will make the most of your water and will ensure that you are not wasting any while the tap is running. †¢ To save both water and energy, if youre not already using green energy, then you should wait until your dishwasher is completely full before running it. On average, dishwashers use approximately 40 liters of water per load, but thanks to features that some dishwasher have, you can specify that it is a light load, or rinse only, or air dry. All of these features allow you to save both water and energy. Goals of Water Conservation The goals of water conservation efforts include as follows: Sustainability: To ensure availability for future generations, the withdrawal of fresh water from an ecosystem should not exceed its natural replacement rate. Water efficiency: Water efficiency can be defined as the accomplishment of a function, task, process, or result with the minimal amount of water feasible, or an indicator of the relationships between the amount of water needed for a specific purpose and the amount of water used, occupied or delivered. Energy conservation: Water pumping, delivery, and wastewater treatment facilities consume a significant amount of energy. In some regions of the world over 15% of total electricity consumption is devoted to water management. Habitat conservation: Minimizing human water use helps to preserve fresh water habitats for local wildlife and migrating water flow, as well as reducing the need to build new dams and other water diversion infrastructure. Water conservation: Water conservation refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning, manufacturing, and agricultural irrigation. Water Saving Tips * Monitor your water for unusually high use. Your bill and your water meter can help you to discover leaks. * Water your lawn and garden in the morning or evening when the temperatures are cooler, to minimize evaporation. * Wash your fruits and vegetables in a pan of water. Reuse it to water the plants. * Check outdoor faucets, sprinklers and hoses for leaks. * Upgrade older toilets with water efficient models * Water can also be conserved by landscaping with native plants. * Shorten your shower by a minute you will save up to 150 gallons per month. Taps with low flow and high pressure can be used. * Put a weighted object in the toilet tank to displace water so less is used with each flush in conventional water closets. * Run only full loads in the washing machine and dishwasher. EXTRA MEASURES: There is a gap between the seasonal availability of water and its equitable supply throughout the year. Accordingly the storage of water and passage through soils is very important. It is well known that about 70% area in this country is subject to varying degree of water stress. There are areas with heavy rainfall but water problems become predominant during non-monsoon periods. It is thus a matter of concern to create a redistribution system and requirements as and when it is needed. Although there are many methods for water management, the two important methods are mentioned as follows. Rain Water Harvesting: Rain Water Harvesting as a method of utilizing rain water for domestic and agricultural use is already widely used throughout the world. It is a method which has been used since ancient times and is increasingly being accepted as a practical method of providing potable water in development projects throughout the world. It has wide application also in urban and peri-urban areas where the reliability and quality of piped water is increasingly being questioned. Despite these facts the percentage of households using rain water harvesting in Zimbabwe both in urban and rural areas is remarkably low. Social solutions: water conservation programs are typically initiated at the local level, by either municipal water utilities or regional governments. Common strategies include public outreach campaigns, tiered water rates (charging progressively higher prices as water use increases), or restrictions on outdoor water use such as lawn watering and car washing. Watershed Management: A watershed is an area bounded by the divide line of water flow so that a distinct drainage basin of any small or big water course or stream can be identified. The rain falling over this area will flow through only one point of the whole watershed. In other words, the entire area will be drained only by one stream or water course. In this way we will have definitive water resource which can be assessed and analyzed for planning for the optimum utilization through ground water, wells, tube wells, small ponds, bigger tanks or reservoirs. Watershed management is very important for rainfall and resultant run-off. More than 900 watersheds of the flood prone rivers have been identified and are at present in operation. The development of delayed through propagation of water harvesting technology is also based on the concept of micro watershed. Himalayas are one of the most critical watersheds in the world. The damage to reservoirs and irrigation systems and misused Himalayan slopes is mounting as are the costs for the control measures during the flood season every year. The vast hydroelectric power potential can be harnessed from the Himalayas watersheds on a sustainable basis. The concept of water shed management has been extended to agro-industrial watersheds which take care of agro-industrial development. Awareness on Soak Pit: A soak pit is a covered porous-walled chamber that allows water to slowly soak in the ground. Pre-settled effluent from a collection and storage or treatment chamber is discharged to the underground chamber from where it infiltrates into the surrounding soil. Conclusion †¢ We must use our water wisely. Earlier water has been abundant resource and unfortunately was used carelessly. Today water is a precious resource to us and to future generations. Life wouldnt be the same without it. †¢ Water is one of nature’s most important gifts to mankind. Essential to life, the survival of all living beings depends on water.

Cell Structure And Transport Biology Essay

Cell Structure And Transport Biology Essay Cells can be split into two types, prokaryotic (see figure 1) and eukaryotic (See figure 2). Karyose originates from a Greek, meaning kernel, as in a kernel of grain. In physiology, it is used to refer to the nucleus of a cell. Pro means before, and eu means true. Therefore you could say that prokaryotic means before a nucleus and eukaryotic means possessing a true nucleus. (Wikipedia) Prokaryotic and eukaryotic cells have many differences and few similarities. Eukaryotic cells and lager than prokaryotic cells, a eukaryotic cell is usually 10nm in diameter where as a prokaryotic cell in 1nm in length.(Class Notes) Eukaryotic cells contain a nucleus, protected by a double membrane. Prokaryotic cells do not contain a nucleus. The purpose of the nucleus is to sequester the DNA-related functions of the big eukaryotic cell into a smaller chamber, for improved efficiency. This function is unnecessary for the prokaryotic cell as the cell is smaller and all materials within the cell are close together. However prokaryotic cells do have DNA and DNA functions. Eukaryotic DNA contains proteins called histones, and these are organised into chromosomes; prokaryotic DNA has no histones, there are no chromosomes in a prokaryotic cell. A eukaryotic cell contains a number of linear chromosomes; a prokaryotic cell contains only one circular DNA molecule and a varied assortment of much smaller circlets of DNA called plasmids. A prokaryotic cell is smaller and simpler; it requires far fewer genes to operate than the eukaryotic cell. (Rowlands, 2000) Eukaryotic cells contains large numbers of mitochondria, the number of these varies according to the size and type of cell. Mitochondria support the protein of the electron transport chain of the aerobic respiration within the cell supplying the cell with ATP, but this organelle is not located in a prokaryotic cell. (Williams) Eukaryotic cells also contain endoplasmic reticulum, however there is none present in a prokaryotic cell. Endoplasmic reticulum comes in two forms, rough and smooth. Rough endoplasmic reticulum helps to compartmentalize the cell, and it serves as routes for the transport of materials from one part of the cell to another. It is also associated with lipid synthesis and protein synthesis. Smooth endoplasmic reticulum is responsible for generating new layers for golgi bodies. Golgi bodies are stacks of sacs called cisternae. The function of golgi bodies is to process materials manufactured by the cell. The other kind of golgi vesicle contains materials to be secreted from the cell. These materials are not waste products but chemicals manufactured by the cell for export (hormones and pheromones for example). Prokaryotic and eukaryotic cells have many ribosomes, however the ribosomes of the eukaryotic cells are larger and more complex than those of the prokaryotic cell. Ribosomes are made out of a special class of RNA molecules and a specific collection of different proteins. A eukaryotic ribosome is made up of five types of rRNA and approximately eighty types of proteins. However a prokaryotic cell ¿Ã‚ ½s ribosomes are made up of only three types of rRNA and approximately fifty types of protein. The cytoplasm of eukaryotic cells contains a complex collection of organelles and many of the organelles are enclosed in their own membranes. However the prokaryotic cell contains no membrane-bound organelles that are independent of the plasma membrane. Some prokaryotic cells contain flagella. These organisms which are usually single celled and are used for locomotion. Unlike the flagellum of a eukaryotic cell, this mechanism lacks an internal structure. The prokaryotic flagellum is shaped like a corkscrew and propels the cell where as in a eukaryotic cell where the flagellum is more complex it moves in a lashing action. (Wikipedia) Prokaryotic and eukaryotic cells also differ in regards to what they store. A prokaryotic cell store specialised compounds in the form of granules or droplets. Where as a eukaryotic cell stores glycogen, starch, lipid and in some cases specialised materials of particular organisms. Prokaryotic cells are found in bacteria and blue green algae, eukaryotic cells are found in fungi plants and animals. (Class Notes) To summarise, prokaryotic and eukaryotic cells are similar in the fact that they are both are contained by plasma membranes, filled with cytoplasm and also contain ribosomes. Both contain the same kind of DNA as the genetic code for a prokaryotic cell is the same for a eukaryotic cell. However they have many materials present in a eukaryotic cell which are not present in a prokaryotic cell. This is because a eukaryotic cell is much more complex and has more complex process to complete. Microscopic appearance of squamous cells 2. The attached diagram represents an electron micrograph of a liver cell. Identify the structures: Label A Rough Endoplasmic reticulum B Mitochondria C Nucleus D Nucleus Membrane E Cell Membrane F Smooth endoplasmic reticulum G Cytoplasm 3. Using appropriate detail with diagrams and sizes where needed, explain how the structure of the following organelles is related to their function: A: Rough Endoplasmic reticulum Most ribosomes are attached to the surface of the rough endoplasmic reticulum. The endoplasmic reticulum is a series of interconnecting flattened tubular tunnels, which are continuous with the outer membrane of the nucleus. It runs through the cytoplasm of all eukaryotic cells. The ER of a cell often takes up more than a tenth of the total cell volume. Rough ER appears rough due to the presence of ribosomes on the membrane. The rough ER is concerned with the transportation of proteins, which are made by the ribosomes on the surface of the membranes. The membranes form a series of sheets known as lamellae of reticulum, and these enclose flattened sacs called cisternae. The purpose of this is to form a maze-like structure so that there is a very large surface area for chemical reactions to take place. Information coded in DNA sequences in the nucleus is transcribed as messenger RNA. Messenger RNA exits the nucleus through pores in the nuclear envelope to enter the cytoplasm. At the rib osomes on the rough ER, the messenger RNA is translated into proteins. The newly made proteins are taken into the tubes of the rough ER so that they cannot escape into the cytoplasm, and are threaded through pores in the membrane to accumulate in the cisternal space where they can fold into their normal three-dimensional shape. Proteins made by the rough ER are then either secreted or used where they are needed within the cell. (Roberts, 2009) B: Mitochondria The mitochondrion produces energy in the form of ATP (adenosine triphosphate), which is produced when organic compounds are completely broken down to carbon dioxide and water. One of the main conditions for this process to occur is the presence oxygen. Each mitochondrion has a double-membrane system. The inner membrane is folded repeatedly and it is also known as cristae. The outer membrane faces the cytoplasm. This complex system creates two divisions. In the outer division, enzymes and other proteins stockpile hydrogen ions. These ions then flow into the inner compartment. The energy inherent creates ATP-formation. Hydrogen binds with oxygen to produce the end product, water. (Roberts, 2009) C: Nucleus The nucleus is usually spherical and about 10 ¿Ã‚ ½m across, it has two main functions. Firstly, it segregates all the DNA molecules from the cytoplasm. Secondly, the nuclear membranes administer as a boundary where cells control the movement of substances to and from the cytoplasm. The nucleus is made up from a few constituents. The nuclear envelope is a double-membrane system that has two lipid bilayers in which many protein molecules are firmly established. This prevents water-soluble substances to move without restriction into and out of a nucleus. The second component is nucleolus, which is a highly packed cluster of RNA and proteins, which construct to make subunits of ribosomes. (Roberts, 2009) 4. The structures A and F may be functionally associated in extracellular secretions (as for example salivary glands). Give an illustrated answer to show this association. The rough endoplasmic reticulum is involved in the formation of the Golgi body. The Golgi body is created by the rough endoplasmic reticulum as a sequence of vesicles containing protein. As these come together the protein modifies with carbohydrate molecules attached, this leading to glycopeptides being produced. The glycopeptides are then  ¿Ã‚ ½pinched ¿Ã‚ ½ from the ends of the Golgi body and move toward the cytoplasmic membrane. These then fuse together and a material is secreted. (Class Notes) 5. Lysosomes are important in certain intracellular activities. Using a sequence of annotated diagrams, show the signifigance of these structures in the destruction of unwanted organelles. Lysosomes are organelles that contain digestive enzymes referred to as acid hydrolases. They dissolve and digest excess or worn out organelles,(see figure 4) food particles, and engulfed viruses or bacteria. The membrane surrounding a lysosome prevents the digestive enzymes inside from destroying the cell. Lysosomes fuse with vacuoles and dispense their enzymes into the vacuoles, digesting their contents. They are built in the Golgi apparatus. (humpath.com) 6. Using diagrams describe the basic chemical structure of the cell membrane (the bimolecular components) and explain why this structure is referred to as the  ¿Ã‚ ½fluid mosaic model ¿Ã‚ ½. The cell membrane separates a watery cytoplasm from a watery external environment also referred to as the extracellular fluid. The phospholipids are arranged in a double layer (lipid layer) with the hydrophilic heads facing outward (cytoplasm or extracellular fluid) and the hydrophilic tails turned in towards each other. The unsaturated fatty acids are not bonded to each other therefore forming a fluid. (Williams) Embedded within the lipid bilayer are different proteins (hydrophobic parts interact with the hydrophobic tails of the phospholipids). The hydrophilic parts of the proteins protrude either in to the cytoplasm or into the extracellular fluid. Some of the proteins are anchored in place while other proteins move about within the bilayer. (Williams) Various organelles within the cytoplasm are also bounded by membranes similar in structure to the cell membrane except for specific combinations of lipids and proteins depending on the particular functions of the organelle. (Williams) Some of the proteins extending into the extracellular fluid have carbohydrates (glycoprotein) attached. Fluid mosaic model (Figure 6) The term  ¿Ã‚ ½fluid ¿Ã‚ ½ is used because the phospholipid molecules and proteins that make up the membrane are free to drift around in fluid motion. The term  ¿Ã‚ ½mosaic ¿Ã‚ ½ is used to describe the position of the protein molecules. The molecules are placed randomly and there is no set pattern. (Wikipedia) b. Describe concisely how the phospholipids and the protein molecules in the cell membrane make the membrane selectively permeable and are involved in cell recognition as the therapy using tissues typing/ blood transfusion. The cell surface membrane is the boundary between the cell and its environment; it has very little mechanical strength but plays a vital role in controlling which materials pass into and out of the cell. Cell membranes contain phospholipids, proteins, cholesterol and polysaccharides. The phospholipids are a major constituent of cell membranes. They naturally form membranes in water because they automatically arrange themselves into a bilayer that is practically impermeable to water and anything that is water soluble. ¿Ã‚ ½ The membrane proteins act as hydrophilic pores; these are water filled channels that allow water-soluble chemicals to pass through. These pores are usually small and highly selective, proteins in the membrane that form pores usually span the entire membrane, but other proteins with other functions can occur only in the top or bottom layer of lipids. Some membrane proteins serve as carrier molecules in which ions pass through channels in the protein molecule. The movement of ions may occur through facilitated diffusion. The ions may also move against a diffusion gradient in a process known as active transport. Unlike facilitated diffusion, active transport requires ATP. Membrane proteins may also be associated with cell recognition in which patrolling T-cells and antibodies recognize the shape of membrane proteins as self or foreign. These membrane proteins often contain unique carbohydrate chains (antennae) which are involved in the cell recognition process. Recognition glycoproteins may include receptor sites for some hormones and neurotransmitters and various blood antigens. (Cellsalive.com)

The Aims Of Writing A Literature Review Education Essay

The Aims Of Writing A Literature Review Education Essay What is review of the literature? A literature review is a write-up that aims to review the critical aspects of current knowledge on a particular topic. Its an account of what has been published on a topic by accredited scholars and researchers. Most often associated with science-oriented literature, such as a thesis, the literature review usually precedes a research proposal, methodology and results section. The purpose is to bring the reader up to date with current literature on a topic and form the basis for future research that may be needed in the area. A good literature review is characterized by: a logical flow of ideas; current and relevant references with consistent, appropriate referencing style; proper use of terminology; and an unbiased and comprehensive view of the previous research on the topic. It is not just a descriptive list of the material available, or a set of summaries. Besides enlarging your knowledge about the topic, writing a literature review lets you gain and demonstrate skills in two areas Information seeking: the ability to scan the literature efficiently, using manual or computerized methods, to identify a set of useful articles and books Critical appraisal: the ability to apply principles of analysis to identify unbiased and valid studies. A literature review must do these things Be organized around and related directly to the thesis or research question you are developing Synthesize results into a summary of what is and is not known Identify areas of controversy in the literature Formulate questions that need further research A literature review is a piece of discursive prose, not a list describing or summarizing one piece of literature after another. Its usually a bad sign to see every paragraph beginning with the name of a researcher. Instead, organize the literature review into sections that present themes or identify trends, including relevant theory. You are not trying to list all the material published, but to synthesize and evaluate it according to the guiding concept of your thesis or research question If you are writing an annotated bibliography, you may need to summarize each item briefly, but should still follow through themes and concepts and do some critical assessment of material. Use an overall introduction and conclusion to state the scope of your coverage and to formulate the question, problem, or concept your chosen material illuminates. Usually you will have the option of grouping items into sections-this helps you indicate comparisons and relationships. You may be able to write a paragraph or so to introduce the focus of each section How to do a literature search? Defining the topic In order to begin your literature review you must first define your research question. What is the purpose? What does it mean? What are the key words? Are there other words which could be used, such as synonyms, variations in spelling? What do you already know about the topic? What is the scope? Compiling a list of keywords Analyzing the topic of an essay question or research topic usually involves making a list of keywords or phrases. You will need to include all the key concepts or ideas contained within the essay or research question. It might be useful to include alternative ways of phrasing and expressing concepts and ideas. Think about both general terms and very specific terms for broadening and narrowing your search. The keyword or phrase is the basic unit of any search. You may find it helpful to consult subject dictionaries and encyclopedias, or a textbook glossary for the common terminology of the subject area. The use of an index and/or thesaurus is also advisable to establish the useful terms. Identifying Resources Information is available in a number of formats. It is important for you to understand the significance of various formats so that you know what will best suit your information requirements. Books Reference Materials Journals Conference Papers Dissertations Internet Indexes/Abstracts Printed Electronic Databases Government publications Thesis Putting tables and figures If you found the table or figure in a source, or if you developed the information in the table or figure from a source other than your own primary research, you must cite the full source just below the table or figure, and again include the full source in your list of references at the end of the thesis. Table number and headline is always mentioned on top of the table. Figure number and headline is mentioned at bottom of the figure. The source reference below the figure/table should be in a smaller font, in a bracket, in italics. Like this: Table 4: Numbers Unemployed in Co. Roscommon, 2000 2004 Electoral District Male Age range Female Age range Total (Source: Jones, D. 2004. Impact of unemployment in rural areas of Connacht 2000 2004. Dublin: Folens, p. 56.) Figure 4: Air Supply in Burma (June 1944 to April 1945) (Source: Jones, D. 2004. Environmental Concerns. Dublin: Folens, p. 56.) 2. Bibliography Formats Each citation in a bibliography has to describe a resource in enough detail that someone can go to a library (or out on the net, or to a bookstore), and see it for themselves. Imagine going to a bookshop and saying, Hi. I need that book on World War II. You know, the one that mentions Hitler? Thats why the specifics-formats, titles, authors, dates, etc.- are important. Writing the assessment: What do I need to reference? When you are writing your assessment, be sure to type in reference information as you add in the ideas of other authors. This will save you time and will ensure that you reference all sources properly. Whenever you use someone elses ideas or words, you must put in a reference. The only exception to this rule is when the information you have read somewhere is common knowledge or public domain information. For example, you would not need to include a reference if you stated in an assignment that Shakespeare wrote plays and sonnets in Elizabethan times. You must always reference the following (i) Direct quotations this is when you copy another authors material word-for-word. You should show the reader that it is a direct quote by placing the material in inverted commas. Traditionally, double inverted commas have been used () but it is now acceptable, and preferable to use single inverted commas (). Sometimes it is difficult to avoid the direct quotation as the authors words may precisely describe the point you are trying to make. However, do try to avoid the overuse of direct quotations; try to paraphrase the authors work where possible. Please note that when you use direct quotations, you must reproduce the authors words exactly, including all spelling, capitalisation, punctuation, and errors. You may show the reader that you recognise an error and that you are correctly quoting the author by placing the term sic in brackets after the error. (ii) Paraphrasing this is when you take another authors ideas and put them into your own words. You are still copying someone elses work, so you must reference it. You do not need to use inverted commas when you paraphrase, but you must clearly show the reader the original source of your information. 1. INTERNET RESOURCES In the easy-come, easy -go world of the free internet, dates and addresses are particularly important. Two dates are required: the date that the material was published or updated, and the date on which you actually used it. The address, or URL, of the site must be complete.

How to avoid plagiarism Scientific Misconduct and Plagiarism: Many people say that it is the intellect which makes a great scientist. They are wrong: it is character Albert Einstein In centuries of reading, writing, experimenting and hypothesizing, a persons work will inevitably incorporate and overlap with that of others. However, occasional overlap is one thing; systematic, unacknowledged use of the techniques, data, words or ideas of others is another. Your work has to be carried out honestly and objectively without bias and the results should be reported truthfully. Deviations may occur from the ideal due to ignorance or, at times, they may be willful deceptions. These deviations from the ideal, willful or otherwise, constitute what is known as scientific misconduct. While various types of scientific misconduct have been identified, those that comes to notice usually include fabrication, falsification, plagiarism, cyber-plagiarism, self-plagiarism, and duplicate publication. It is desired that all students should be made aware of these. This note defines plagiarism and sets guidelines. What is Plagiarism? Failure to acknowledge other colleagues scientific work-their ideas, language, or data. Verbatim copying of passages without citing the original contributor, rewording of ideas, paraphrasing, and even total reproduction by simply changing the authors names and trying to pass the material as ones own. Unauthorized use of ideas or unique methods obtained by a privileged communication, such as a grant or manuscript review. Passing off retrospective studies as prospective ones or deliberately omit references to earlier works. How Plagiarism can be detected? One of the important responsibilities of a reviewer is detection of plagiarized text due to his/her familiarity with published material in his/her area of interest. Technology has made it possible to carry out checks for sentences that are copied from previously published articles. There are dedicated web sites available that provide information on plagiarism ( www.plagiarism.org ) and software to detect plagiarism has made it easier for reviewers and editorial staff of journals to detect copying (www.ithenticate.com, www.writecheck.com and www.turnitin.com ). We have recommended to you the VIPER software. Dos and Donts of Plagiarism Some simple tips to be followed to avoid plagiarism are: Take short notes from the source and then write back in your own words without looking back at the original source. Attribute references to any information or idea you are using from other sources, even if you are not directly using it. describe all sources of information Give acknowledgments to the original source by quoting author details at the end of the statement. Give details of the original source by providing footnotes . Use quotation marks wherever required If you are paraphrasing, credit the original source For extensive quotations, obtain permission from the publisher of the original work Obtain permission for use of published drawings or other illustrations Dos and Donts of Research: DO: Make sure you know what question youre trying to answer. Look at all kinds of sources before you narrow in on the ones that will be most useful. Read and digest. Give yourself time to do this. Think critically about what youve just read and how it directly relates to the question. Evaluate what youve got, the holes in your research, and where you need to go from here. Keep a running annotated bibliography going, sorting facts by source or marking your notes with a coding system so as to remember where individual facts came from. Divide your thesis into sections before you begin researching. Make sure you devote energy and time to finding information about all the topics you want to tackle. Remember that the beginning of a thesis presents existing knowledge on a topic, whereas towards the end of a paper, you present your own thoughts. Use a variety of sources. Journals, books, e-books, newspaper and magazine articles, legitimate web sites, and course books can all be good sources, but which ones you use will depend on your topic. Talk to your professor about his or her expectations and ideas for sources. Talk to other students about their strategies for mapping out the research ahead. DONTS: Stuff so much information into your head at once that you cant remember what you learned and where you learned it from. You will lose sight of the point of the research project. Cite Wikipedia. Wikipedia is good for getting general information, but find an absolutely reliable source for your citations. Plagiarize. Learn what constitutes plagiarism and how to use sources responsibly. Dos and Donts of Internet Research The internet provides a rich resource of information and data however; there is great risk in using this all-too accessible resource. Self-regulating resources like Wikipedia and Google- or yahoo-search readily provide us with answers to just about any question we may pose. But which is it the right answer? And, is it the right answer? The very accessibility of online information makes it risky and often questionable. You need to be more vigilant of the veracity and reliability of your sources when acquiring information from the internet. To ensure that your information you have got is sound, one can do several things: Use more than one source, particularly for important things; this will give you a wider range of material from which to discern accuracy and reliability. Verify your sources and preferably cross-reference to measure out objective truth vs. bias. Try to use primary sources (original) vs. secondary or tertiary sources (original cited and open to interpretation); the closer you are to the original source, the closer you are to getting the original study.

Mark Twains The Adventures of Huckleberry Finn :: Adventures Huckleberry Huck Finn Essays

The Adventures of Huckleberry Finn      Ã‚  Ã‚  Ã‚   In the novel, The Adventures of Huckleberry Finn, Huck Finn was the main character. The story was told through his eyes, and most of the events that took place happened around him.   But some of these events would not have happened without other main characters as well, like Jim, Tom Sawyer, the King, or the Duke.   Ã‚  Ã‚  Ã‚   Huck’s personality at the start of the novel had changed gradually throughout the novel and until the end.   At first, Miss Watson tried to make him pray for things but Huck did not believe in praying because it brought him bad luck.   Later in the novel, Huck tries to pray for forgiveness and wants to erase his sin for stealing a nigger.   After he prays, he feels he can pray openly now and will not sin anymore (CH. 31).   Huck was also superstitious and believed that everything that went wrong was because of certain things he did, like the snake in Jim’s blanket.   And everything was blamed on the bad luck Huck and Jim had.   Huck also became kind, especially after the quarrel with his father, pap.   He learned that in order to get along with people (like the king and duke), you have to let them have their way, and Huck did.    Jim, at first, was looked upon as just an ordinary nigger.   But Huck and Tom soon realized that he was very smart and had helped Huck through most of his adventures.   But as a nigger, Jim was looked up to as a hero to other niggers.   For instance, Huck tells the reader when niggers from all over the country came to see Jim and hear of his heroic stories and every nigger wanted to be like Jim.   Jim was also very superstitious, especially in chapter eight when Jim talks about all of his superstitions, like counting the things for dinner and telling the bees that their owner had just died.   All of this supposedly brought bad luck.   Ã‚   Tom Sawyer was also a very influential character to the story.   He was the one who came up with all the solutions for things, which eventually made more of a disaster.   But that is because he followed stories too much.   For instance, in chapter 35, Jim is captured and Tom tries the most original and hardest way to get him out, thus creating more of a catastrophe.

The Nature of Douglasss Narrative of the life of Frederick Douglass Es

The Nature of Douglass's Narrative of the life of Frederick Douglass Frederick Douglass wrote his autobiography the Narrative of the life of Frederick Douglass to tell his story and to help the abolitionist's cause. It provides a window into his world, which is that of a former slave and of a prominent speaker. Douglass was born a slave in Maryland in 1818; his exact birthday is unknown. Unlike most slaves he had a mistress, Sophia Auld, who taught him his letters when he was about 10 and that basis of knowledge allowed him to 'steal literacy' over the years. Douglass was hired out to a slave breaker named Edward Covey in order to make him more subservient. In 1834 Frederick Douglass and Edward Covey had a battle which changed the course of Douglass?s life, and shaped him into a man who speaks and acts out against injustice. After Fredrick Douglass stood up to Covey he became free in sprit, if not in body, and vowed to allow no one to control his mind again. He escaped slavery and went to New York in 1839. His career as a speaker started in 1841 and in 1845 he published the Narrative. Although, those are some of the basic facts about his life but they do little to describe the man that he was, and what his first work says about himself and what he believed. The Narrative was written after he had spent a few years as a speaker going around telling his life?s story to abolitionist and therefore was in part rehearsed and also meant to be used as propaganda in the fight for equality. The book also serves as a historical source because it documents his voyage though slavery and the movement to end it. It is important when reading his autobiography to keep both views in mind. Many people have analyzed this complex work, Donald B. Gibson wrote about Douglass?s dual focus in his writing about how he had a public and social focus and a personal focus and private. The public and social focus was to correct the moral and political ills that slavery brought. While the personal and private focused on Douglass?s own thoughts, feelings, reactions, and emotions. The social focus was what presented the first twenty-one years of Douglass?s life in a way that allowed it to serve as a weapon for abolitionism. William Lloyd Garrison and Wendell Phillips recognized the public perspective, both of which wrote prefatory material to the Narrative. I... ...hen reading Frederick Douglass?s Narrative of the Life of Fredrick Douglass it is important to take in to account the time period in which it was written, who the author was and their background, and the purpose that the work was written for. Douglass was a slave and an abolitionist who wrote about his life for two reasons, to give the facts and to convince people that slavery was wrong. The way he wrote both parts are intertwined so that they compliment and support each other it exist as a work of abolitionist propaganda and as an historical source.

Dead Man Walking Essay examples -- essays research papers

Dead Man Walking   Ã‚  Ã‚  Ã‚  Ã‚  The film â€Å"Dead Man Walking† is a film about redemption. The film is directed by Tim Robbins. Susan Sarandon plays a Nun called Sister Helen Prejean. She is asked by a convicted murderer to get him a lawyer, and then later is asked to be his spiritual advisor. The convicted killer is named Matthew Poncelet, and he is played by Sean Penn. The film is set in the Angola state penitentiary, in Louisiana. Matthew Poncelet first asks her to get him a lawyer so he can repeal his Death sentence. Sister Helen gets him a lawyer, but they fail after several good attempts to get him off death row. Sister Helen begins to come to him almost every day after Poncelet asks her to be his spiritual advisor on the day of his death. During this phase of the film Sister Helen tries to get Poncelet to tell her about his own life. Poncelet tells her about his life and why he was put on death row. Poncelet was convicted along with another man in the murder of the youth and a girl after raping the girl. Sister Helen is very sympathetic and is also looked down upon for this reason. Though she is repressed she still goes on helping Poncelet and she digs around in his feelings and soul. Sister Helen eventually finds a good soul in Matthew Poncelet, a person no one else knows. Matthew constantly denies to Sister Helen, himself, and to God that he had committed his horrible crime. Poncelet continues to blame his problems on other things such as his father dying early in his life, his drug use, his immaturity, and that he was unable to stand up to his partner in the brutal crime. Sister Helen urges Poncelet to come clean and face the part that he took in the crime. And at nearly the last minutes of the film he tells the truth. Though he tells the truth of his sin, he is still put to death by lethal injection.   Ã‚  Ã‚  Ã‚  Ã‚  The purpose of this film, I believe, was to show that capital punishment is not right in all circumstances, but the redemption and preservation of the human soul being better. Tim Robbins tried to show how most people and even more accurate, Christian people tend to always want vengeance for a crime. Most of them have a line from the old testament committed to memory, â€Å"An eye for an eye,† is what they always want to say. But it really confuses me. To me that saying is not clear, if you think about it, i... ...n church. I read the Bible, though not as much as I should, but the â€Å"Eye for an Eye part has always confused me. If the Bible states, â€Å"Thou shall not kill,† then why does it justify the killing of a person who has killed before. I believe that God loves all his children. If people are really followers of Christ, they will learn from him how to forgive people for their faults and mistakes during life. If the people in the film would have stopped and though what it would be like to be in Poncelet’s shoes, maybe they would feel different about the death penalty. He was in jail facing lethal injection. I’m sure if they thought about it they would not want to be killed, but then the people who Poncelet had killed did not have a choice, they had death forced on them. This film does a great job of showing both sides of the capitol punishment controversy. I can see how people think killing someone who has killed is a good thing. It keeps the person off the streets and from killing again. Though is it really justice? I still believe that people can be evil, but people can also be cleansed. I believe this film has a dramatic point, and the purpose is pretty clear to anyone who may watch it.

Pip’s family Essay

In chapter one of the story we discover that Pip’s family is deceased, well apart from his sister. They all died from common diseases like flu and measles and other illnesses which some were treatable but, medicine was not affordable for the poor. The social conditions in the nineteenth century were unfortunate. There wasn’t much medicine and there were no cure for common diseases and there was a lot of poverty, poor people had to work which includes children working in factories, there wasn’t in the least of education for the poor. This all tells us that life was hard to live in Britain in the nineteenth century if you were poor. Today in Britain it is greatly different, there is less poverty, more education, affordable prices for medicine, children don’t need to work to support there family, also there is the NHS health service and there is child benefit along with income support. Pip encounters an escaped convict when he goes to see his mother’s grave. Pip was petrified when he saw this convict; he was an enormous man and was chained up to his legs. In those days all convicts were known as murders so when Pip met him he was horrified. Then the convict forces Pip to bring food to eat and a filer to break lose from the chains on his hands and legs. In Pip’s village the standard of education was important but the poor often couldn’t afford it. Only the rich and wealthy families were able to afford education. Poor people weren’t expected to get educated in Pip’s village. Pip was expected to work and support his family when he was older. Pip wanted to become a black smith like Joe. Charles Dickens wants to create a miserable impression about education among the working classes. He wants to show how unfortunate children were in the working classes as they can not get any education and had to support there families. The children of wealthier families received different standard of education from the poorer families. They weren’t amongst the working classes, they didn’t need to work to support there families they could afford education as well as medicine, which means that life wasn’t bad for rich and wealthy families. Joe and Pip are extraordinarily good friends Because Joe is a fully grown man and Pip is a youngster and there relationship is very secure and close, they can talk to each other in confidence, can keep secrets from each other and support each other in any way. Joe had an extremely dreadful childhood he suffered from a lot of violence from his dad as he gave a great deal of pain to Joe and his mother by beating them. Joe’s dad was constantly drunk also, they were suffering from poverty. Joe explains his father and childhood to Pip. He tells him about the violence he suffered from his father this makes Pip feel uncomfortable and sorry about Joe. â€Å"†¦I was not at all at my ease†¦Ã¢â‚¬  this is how Pip felt, he felt anxious and confused when the time was up to go to Miss Havisham’s house for the arrangement. At the gates of the Satis house Pip met Estella. Estella treated Pip awfully bad. She kept on calling him â€Å"†¦boy†¦Ã¢â‚¬  at the end of her every sentence, this was very impolite and rude. By Estella’s words and actions it made Pip feel like someone not to be complimented at even for this Pip had feelings for Estella. Estella knows that pip comes from a poor social background. She feels that he is someone that has no education and manners so she speaks to him very rudely by calling him not by his name but by â€Å"†¦boy†¦Ã¢â‚¬  at the end of every sentence. When Pip left the Satis house he felt like a â€Å"†¦common labouring-boy†¦Ã¢â‚¬  and felt more ignorant because he cried in front of Estella at the gates of the Satis. Pip was very irritated by the way Joe was dressed, which it was in his Sunday clothes and he also was irritated when Joe’s behaviour was very embarrassing during their meeting with Miss Havisham. Joe was trying to act smart and act like a gentleman but he made things worse by tying to say big words like â€Å"Astonishing† but he said it all wrong he said it like â€Å"†¦as-TON-ishing†¦Ã¢â‚¬  this made Pip feel more irritated and Nervous. When Joe was speaking to Miss Havisham he was addressing to Pip, Pip was trying to give him a clue to stop Joe from looking at him and to look at Miss Havisham when speaking to her but Joe was to dense to notice. This all is showing us that Pip’s attitude changes towards Joe; he starts feeling ashamed about Joe because he showed out Pip’s social and financial life at the meeting with Miss Havisham by the way he speaks and dresses. I don’t think Pip should have felt this way because Joe is his close friend and he should not change his feelings and actions towards Joe just because he gets irritated at him. Now we can see that Pip’s social life and poverty is affecting his own character.
