The Interaction Between Body and Writing :: Teaching Writing

The Interaction Between Body and Writing My first text for this assignment was this haiku: thank god for spring in Ypsi; makes it easier to get out of bed. It seemed appropriate to the task of attempting to write in English without using any technology, as the haiku form is traditionally concerned with the natural world. I envisioned the grass and earth on my property, newly bared to the sun again after the snows, and the letter-making materials available on the site. I could hear my paper unfolding in my head; since the point of the project was to come to terms with the bonded nature of language to technology in writing, I could see whole paragraphs about my use of found sticks and mud as well as bits of discarded junk that my landlord had left lying around since last fall. My argument would be that the use of materials that had originated from the natural world and been manipulated by technology that were now returning to their natural home symbolized the interwoven relationships between thought and feeling and action that is written communication. I had some lovely big ideas. But then I started wandering around in my head a little bit, and some interesting questions came up. Having grown up in ballet and still acting in the world to some extent as a dancer, I wondered if dance is also a technology in the same way that the alphabet and writing are. It seems to me that social dance, while it does serve the purpose of communication to some extent, has no articulated 'alphabet' of signifiers that compare to words and letters. Dance forms like ballet and flamenco, however, most definitely do. For the trained dancer and the educated audience member, ballet is a system of movement with numerous gestures, movements and shapes that signify specific meanings. The manner in which dance is formed, however, via the body of the 'author,' doesn't perform the same separating function that Walter Ong claims writing does in his essay Writing is a Technology that Restructures Thought. The technology of dance is contained within the author, but the technology of writing is e xternal to the author. While writing "promotes 'objectivity'" by distancing the performer from his/her ideas via performance (326), dance to some extent preserves the unity of thought/emotion and the thinker. With my confidence shored up by Naomi Baron's discussion of the

Central Asia: Geography, Culture and Economy Essay

Russia is the largest country in the world in terms of area covered. The gigantic size of this country has made it exhibit monotony and diversity in its physical and human geography. The eastern plains of Russia from north to south are covered sequentially by tundra, taiga or coniferous forests, mixed forests with trees that have characteristic broad leaves, steppe or grasslands and a semi desert on the fringes of the Caspian Sea. These changes in vegetation are mainly as a result of climate changes. The eastern European plain covers most of European Russia. The western Siberian plain is the largest plain in the world, and stretches from the Urals to Yenisei River (Rowntree, 2011). The topography and vegetation is usually very uniform in the natural zones. Russia therefore presents a delusion of uniformity. Most of the major vegetation zones of the world are found in Russia except tropical rain forest (Rowntree, 2011). Nearly 11 % of Russia is tundra. This type of vegetation is tree-less and is found in the north most part of Russia extending from the border with Finland in the west to the Bering Strait to the east. This stretch the covers from Kamchatka peninsula in the north to the Pacific coast in the south. The taiga is the vastest natural region in Russia. Covers eastern Russia and western Siberia plains to the north and accounts for 60% of Russia (Rowntree, 2011). Very few tracts of land in the taiga are agriculturally viable. Those suitable for farming are located in the European fraction of Russia. The taiga is however the world’s biggest reserve of coniferous forests. A large section of the mixed forest has been cleared for agricultural purposes due to its agriculture potential. This is especially in Eastern Europe. The steppe is also favorable for agriculture due to modest temperatures and sufficient amount of sunshine and moisture. However, the area is at times adversely affected by excess rainfall and disastrous drought and very dry soils (Rowntree, 2011). There has been established a linkage between poor health and obliteration of ecosystems in Russia. Environmental degradation control measures who normally ignored in Russia till the 1990s when the government realized a vast area of the country was under ecological stress. The three major adverse environment conditions in Russia include; the nuclear disaster at Chernobyl – Ukraine in 1986, aridity of the Aral Sea and irradiation of northern Kazakhstan which is a nuclear testing site (Rowntree, 2011). The cost of rectifying these three events is by far more than the cost of any mitigation efforts else where in the world. Currently nearly 85% of the air in urban Russia is polluted. About 75% of the surface water in Russia is also polluted. Most of the rivers in Russia are agents of waterborne diseases. Nearly 80 million hectares of farm land in Russia has been exposed to industrial toxics, pesticides and other chemicals (Rowntree, 2011). Most of the forests in Russia have also been affected by acid rain from the European and Siberian industries. Radioactive contamination of the water has spread to the Japanese sea resulting into a conflict between the two countries. Indigenous people are currently faced with a tremendous crisis with the dawn of globalization. They are faced with extinction, survival or renewal in a continuously globalizing world. These communities lack a voice and are easily cleared by market forces (Rowntree, 2011). Globalization is therefore not only a marginalization factor for the indigenous communities, but a threat to their very existence. Indigenous people are normally found in the world’s most pristine areas which are most sought after by developers. Such areas are rich in forests, minerals among other valuable natural resources. New technological advances are also alienating the native communities (Rowntree, 2011). Global economic agreements have also contributed to the demise of hunters and gatherers. Finally, most indigenous people have ended up being displaced to pave way for activities such as mining and dam construction (Rowntree, 2011). Most governments do not consult the native communities when making decision concerning international trade. These communities are a rich reserve of indigenous knowledge and culture which are vital in the preservation of the natural world (Rowntree, 2011). Hard access to the coast does not necessarily obstruct trade and industry development on developing nations. Nonetheless, developing countries, which lack access to the sea, record reduced trade expansion, Europe being the only exemption to this occurrence. Being land locked has a major negative impact on trade thus affecting the country’s economy (Rowntree, 2011). Land -lockedness is estimated to reduce trade by about 80%. The distance between a landlocked country and the nearest port is a major factor affecting trade level disparities among landlocked countries. This is a reason why most of central Asia countries are economically affected by their geographic location compared to land locked nations in Europe whose distance is shorter compared to those in central Asia (Rowntree, 2011). For instance, Switzerland and Austria are more advantaged compared to land locked countries in central Asia because these countries lack the bargaining power for reduced transit costs (Rowntree, 2012). Compared to land locked countries in Europe, those in central Asia are remotely located from major world markets. Central Asia is divided into three major zones physically. These are; northern belt steppes (north of Caspian sea, Dzungaria and Tarim basin), southern belt, south of Aral sea (Khorezm, Amu Darya) and north east Iran desert (Khorasan and Margiana) (Rowntree, 2011). Islam is the major religion in central Asia with most of them being Sunni. Initially Zoroastrianism was the major religion. It had roots in Afghanistan. Buddhism was also common before arrival of Islam. Among the Turkic people, Tengriansim was more common before Islam was introduced. In Mongolia, the most common religion is Tibetan Buddhism. In this region shamanism is also common. A form of Christianity called Nestoriansm was commonly practiced in central Asia. Russian is the most common language in this region. However, mandarin Chinese is also common in Mongolia (Rowntree, 2011). Turkmen is mainly spoken by former Soviet Union central Asia nations. Other languages include Tibetan language spoken in the Tibet plateau. Central Asia is also at the cross road of shamantic and Buddhism practices. There is also a form of oral poetry chiefly practiced in Kyrgyzstan and Kazakhstan. Photography is also common in former Soviet Union nations such as Uzbekistan due to the influence of Russia. Other forms of arts include Manas which is a style of singing in Kyrgyzstan (Rowntree, 2011). Among the five major nations in central Asia, Kazakhstan is the most economically empowered followed by Turkmenistan. The poorest of these nations is Kyrgyzstan with a gross domestic product per capita of $850. Economic progress has been held back by the fact that this region is negatively affected by external influences and has for time served as a battle ground for world powers. Despite its rich natural resources, the region in general has not been able to exert its control on these resources (Rowntree, 2011).

Why the Department of Homeland Security Was Created

Why the Department of Homeland Security Was Created The Department of Homeland Security is the primary agency in the U.S. government whose mission is to prevent terrorist attacks on American soil. Homeland Security is a cabinet-level department  that has its  origins in the nations response to the attacks of Sept. 11, 2001, when members of terrorist network al-Qaeda hijacked four American commercial airliners and intentionally crashed them into the World Trade Center towers in New York City, the Pentagon near Washington, D.C., and a field in Pennsylvania. Unified, Effective Response to Terror President George W. Bush  initially created Homeland Security as an office inside the White House  10 days after the terrorist attacks. Bush announced the creation of the office and his choice to lead it, Pennsylvania Gov. Tom Ridge, on Sept. 21, 2001. He will lead, oversee and coordinate a comprehensive national strategy to safeguard our country against terrorism and respond to any attacks that may come, Bush said. Ridge reported directly to the president and was assigned the task of coordinating the 180,000 employees working in the nations  intelligence, defense and law  enforcement agencies to protect the homeland. Ridge described the daunting role of his agency in a 2004 interview with reporters. We have to be right a billion-plus times a year, meaning we have to make literally hundreds of thousands, if not millions, of decisions every year, or every day, and the terrorists only have to be right once, Ridge said.   One lawmaker, citing the biblical story of Noah, described Ridges  monumental task as trying to build an ark after the rain has already started falling. Creation of Cabinet Department Bushs creation of the White House office also marked the beginning of a debate in Congress to establish a Department of Homeland Security in the broader federal government. Bush initially resisted the idea of moving such an important responsibility into the Byzantine bureaucracy, but signed onto the idea in 2002. Congress approved the creation of The Department of Homeland Security in November 2002, and Bush signed the legislation into law that same month. He also nominated Ridge to be the first-ever secretary of the department. The Senate confirmed Ridge in January 2003. 22 Agencies Absorbed  By Homeland Security Bushs intention in creating the Department of Homeland Security was to bring under one roof most  of the federal governments law-enforcement, immigration and anti-terror-related agencies. The president moved 22 federal department and agencies under Homeland Security, as one official told The Washington Post, so we are not doing things in stovepipes but doing it as a department. The move was portrayed at the time as the largest reorganization of the federal governments responsibilities since World War II. The 22 federal departments and agencies absorbed by  Homeland Security are: Transportation Security AdministrationCoast Guard  Federal  Emergency Management Agency  Secret Service  Customs and Border ProtectionImmigration and Customs EnforcementCitizenship and Immigration ServicesCritical Infrastructure Assurance Office of the Department of CommerceNational Communications System of the Federal Bureau of InvestigationNational Infrastructure Simulation and Analysis CenterEnergy Assurance Office of the Department of Energy  Federal Computer Incident Response Center of the General Services AdministrationFederal Protective Service  Office of Domestic PreparednessFederal Law Enforcement Training Center  Integrated Hazard Information System of the National Oceanic and Atmospheric AdministrationNational Domestic Preparedness Office of the FBIDomestic Emergency Support Team of the Department of JusticeMetropolitan Medical Response System of the Department of Health and Human ServicesNational Disaster Medical System of the Department of Health and Human ServicesOffice of Emergency Preparedness and the Strategic National Stockpile of the Department of Health and Human Services Plum Island Animal Disease Center of Department of Agriculture Evolving Role Since 2001 The Department of Homeland Security has been called on numerous times to handle catastrophes other than those caused by terrorism. They include cyber crimes, border security and immigration, and human trafficking and natural disasters such as the Deepwater Horizon oil spill in 2010 and Hurricane Sandy in 2012. The department also plans security for major public events including the Super Bowl and the presidents State of the Union Address. Controversies  and Criticism The Department of Homeland Security came under scrutiny almost from the moment it was created. It has endured stinging criticism from lawmakers, terrorism experts and the public for issuing vague and confusing alerts over the years.   Terror alerts: Its color-coded alert system, developed under Ridge, was widely ridiculed and criticized for not being more specific about how the public should respond to elevated threats. The system used five colors - green, blue, yellow, orange and red - to inform the public in real-time about the threat of terrorism.Appearing on the  Tonight Show  with Jay Leno in November 2002, Ridge was pressed by the comedian:  Im sitting at home in my underpants watching the game and, boop, were in yellow. What do I do now?  Ridges response: Change shorts. Nonetheless, the color-coded alerts were a source of frustration among Americans who were being told  to be on alert, but werent sure about what to look for.Duct tape: So, too, was the departments 2003 directive that Americans stock up on  duct tape and plastic sheeting to seal the windows and doors of their home in the event of a terrorist attack.Harold Schaitberger, general president of the  International Association of Fire Fighters, told the  Chicago Tribune: Most of the suggestions, I dont believe, are effective at all in really helping to protect anyone from many of these biological and chemical threats.  I mean, duct tape and plastic? Wheres the good air coming from? Hows it going to be recirculated? Beyond the fact that we already know, for nerve gas and other elements, the plastic is totally ineffective.Quipped Leno: This means the only people who are going to survive an attack are serial killers. Who else has duct tape and plastic sheeting in their car? Going global: Homeland Security has also caused friction between the United States and some European countries for deploying about 2,000 special agents and immigration workers to more than 70 countries, as The New York Times reported in late 2017. The United States under President Donald Trump was accused of trying to export its immigration laws, the newspaper reported.Katrina: Homeland Security came under the most intense fire, however, for its response to and handling of the devastation wrought by Hurricane Katrina in 2005, the costliest natural disaster in American history. The agency was hammered for not developing a national response plan until two days after the storm hit.If our government failed so utterly in preparing for, and responding to, a disaster that had been long predicted and was imminent for days, we must wonder how much more profound the failure would be if a disaster were to take us by complete surprise, said Republican Sen. Susan Collins of Maine, who called Home land Securitys response  alarming and unacceptable.   Department of Homeland Security History Here is a timeline of key moments in the creation of the Department of Homeland Security. Sept. 11, 2001: Members of the terrorist network al-Qaeda, acting under the direction of Osama bin Laden, orchestrate a series of attacks on the United States after hijacking four airplanes. The attacks killed nearly 3,000 people.Sept. 22, 2001: President George W. Bush creates the Office of Homeland Security in the White House, and chooses then-Pennsylvania Gov. Tom Ridge to lead it.  Nov. 25, 2002: Bush signs the Congress-passed bill creating the Department of Homeland Security in the federal government. We are taking historic action to defend the United States and protect our citizens against the dangers of a new era, Bush said at the ceremony. He nominated Ridge to be secretary.Jan. 22, 2003:  The U.S. Senate, in a  unanimous, 94-0 vote, confirms Ridge as the first secretary of the Department of Homeland Security. Bush issued a prepared statement afterward that read: With todays historic vote, the Senate has demonstrated our shared commitment to doing everything we can to s ecure our homeland. The department initially has about 170,000 employees. Nov. 30, 2004: Ridge announces he plans to step down as secretary of Homeland Security, citing personal reasons. I just want to step back and pay a little more attention to personal matters,  he told reporters. Ridge served in the position through Feb. 1, 2005.Feb. 15, 2005: Michael Chertoff, a federal appeals court judge and former assistant U.S. attorney general credited with helping investigators link the terrorist attacks to al-Qaeda, takes over as the second Homeland Security secretary under Bush. He departed at the end of Bushs second term.Jan. 20, 2009: Janet Napolitano, the governor of Arizona, was tapped by incoming President Barack Obama to serve as Homeland Security secretary in his administration. She resigned in July 2013 to become the head of the University of California system after becoming embroiled in the debate over immigration; she was accused both of being too harsh in deporting those living in the United States illegally and not acting forcefully enough to sec ure the nations borders. Dec. 23, 2013: Jeh Johnson, a former general counsel to the Pentagon and the Air Force, takes over as the fourth Homeland Security secretary. He served through the remainder of Obamas tenure in the White House.Jan. 20, 2017: John F. Kelly, a retired Marine general,  and incoming President Donald Trumps pick, becomes the fifth Homeland Security secretary. He served in the position through July 2017 and became chief of staff to Trump.Dec. 5, 2017: Kirstjen Nielsen, a  cybersecurity expert  who worked in the Bush administration and as a deputy to Kelly, is confirmed as Homeland Security secretary to replace her former boss. The department has grown to 240,000 employees, according to published reports.

The Best SAT Math Practice Tests and Questions

The Best SAT Math Practice Tests and Questions SAT / ACT Prep Online Guides and Tips For SAT Math prep, no matter your strategy- whether you’re doing self-study, taking a prep class, or working with a tutor- you need to be working with real SAT Math practice materials. The SAT Math test will be different from any other math test you’ve taken. You need to work with the real material to get used to the pacing and style of this unique test. In this short guide, I’ll show you where to find official SAT Math practice tests and questions, and go over what materials to avoid. Best SAT Math Practice Tests, Free and Official All of the following SAT Math tests are completely free. We've gathered together all of them in one place for your convenience. There are currently 10 official practice tests. You can download them here or take them online at Khan Academy (see next section for more details). Math Practice Test 1 Pages 34-56 Math Practice Test 2 Pages 32-53 Math Practice Test 3 Pages 32-55 Math Practice Test 4 Pages 30-54 Math Practice Test 5 Pages 38-65 Math Practice Test 6 Pages 42-67 Math Practice Test 7 Pages 34-59 Math Practice Test 8 Pages 36-61 Math Practice Test 9 Pages 458-482 Math Practice Test 10 Pages 332-353 You can find the scoring guides and answer explanations onthe official College Board website. The official SAT prep bookis not worth purchasing because it's all available for free online. The only reason you might want to buy it is that it includes eight of the practice tests listed above in print form so you don't have to print them out yourself (it's missing tests 2 and 4). Official Math SAT Prep at Khan Academy If you want a little extra prep (which you likely will since there aren't many official practice tests), there are a bunch of official Math practice questions available as part of Khan Academy’s free SAT prep.To access them, you’ll need to sign up for an account, but it's free and tracks your progress over time. On Khan Academy, the SAT lessons and practice questions are divided by type, so they're very helpful for more targeted studying.There’s a lot of math content, which can help you brush up on concepts you might have missed or forgotten. You can see a sample Math question below: Math Practice Questions on the Official SAT Website Finally, the College Board offersa short SAT Math practice sectionon its website. This feature includes30 calculator questionsand18 no-calculator questions. These are all different from those in the 10 practice tests above, so if you'd like more SAT Math practice, this is a great resource to use. The only drawback to these online SAT Math questions is thatthey're not given in a practice test format- rather, you'll be shown the correct answer after every question. Nevertheless, the quality of these questions is unbeatable. Additional SAT Math Materials In general, I recommend against any SAT Math practice tests that were not written by the College Boardas it won’t be realistic practice.You want to use real practice materials so that you can ensure you’re taking tests that reflect the actual content and difficulty of the SAT. If you take practices tests made by other companies, they might be more or less difficult and might not include all the content on the actual SAT Math section. That said,unofficial tests can still be great for practicing math skills- just not for practicing SAT-style questions. SATMath, more than any other section on the test, is based on knowledge, so having plenty of materials to practice the different math skills required is important (and poor or inaccurate formatting doesn't always matter as much). Check out our massive collection of SAT study material for a list of both official and unofficial SAT practice tests. If you still want more SAT Math study material- and don't mind spending a little cash- look at our guide to the best SAT Math prep books. Get your study on! How to Use SAT Math Practice Tests Effectively: 4 Tips Since you have a limited number of full-length SAT practice tests (with a total of 10 Math practice tests), each one is a precious commodity. You need to make sure you get the most out of each one. Here are my top four tips to best use your SAT Math practice tests: Tip 1:Take Full-Length Practice Tests Under Realistic Testing Conditions Take each full-length SAT practice test in one sitting with accurate timing and realistic testing conditions. That means sitting for about four hours (if you're including the Essay in your practice). Only allow yourself the prescribed time per section; the time allowed is listed at the beginning of each section. Use a watch to time yourself. You need to get used to the timing of the SAT and learn to pace yourself.Don’t give yourself any extra time on a section.If you do, you might be able to answer extra questions and therefore artificially inflate your score. Remember, you want these practice tests to be reliable indicators of your real SAT score, so no cheating! I recommend taking each official SAT practice test in one sitting (in other words, don't sit for the Math tests one day and then taking the Reading and Writing tests another day).The SAT is a marathon, and you won’t be fully prepared for it if you don’t take the practice tests in one go. If you don’t have time to take each of the official practices tests in one sitting (one sitting will be about four hours per test), then you can split the sections over multiple days, but make sure you take at least one full section each day (e.g., you complete the whole Math No Calculator section). NOTE:Realistic testing conditions means obeying all test rules. On the SAT Math section, be sure to only use your calculator on the calculator-permitted Math section (section 4)- and do not use your calculator on the No Calculator section (section 3). You need to get used to doing mental math! Don’t cheat in your practice or you won’t be prepared the day of the SAT. Use a watch, not a phone! Tip 2: Review Your Practice My second tip is toreview your practice tests!When you finish, score your practice test.Then, look at the in-depth answer explanations for every question you got wrong. Try to figure out where you went wrong.Do not skip this step! If you do, you're not going to learn from your errors, and you'll continue making them. Spend at least an hour reviewing your SAT practice tests (or at least 15 minutes per section). While it might seem like a lot of study time wasted, I promise it’s not. It’s the most valuable time spent because it’s the time where you’ll learn from your mistakes. If you don’t have a lot of study time, I recommend taking two SAT practice tests with detailed review, and then at least four SAT Math practice tests with no review. Tip 3: Practice Skills Between Tests Some students see the improvement they want by simply taking practice tests and familiarizing themselves with the pace and style of the SAT. However, most students need to review math concepts that they forgot, never learned, or never quite mastered. In-between practice tests, I highly recommend that youread our individual SAT Math content guides. These guides address the specific content areas (i.e., Coordinate Geometry, Trigonometry, Systems of Equations, etc.) that you need to master to do well on SAT Math. After taking your first practice test, see whether you can figure out why you got thosemath questions wrong.Did you skip a step? Did you misread the question? Or did you not know the content needed to solve a question? If you didn't know how to solve a question, then you need to review that content! Tip 4: Get Help If You Need It If you’re not improving with each practice test, look for extra help: consider supplementing the SAT practice tests with a tutor, class, book (such as the ones above) or program.While some people might be able to learn from their mistakes on practice tests through self-study, most need outside help to identify their weaknesses and to help them improve. Whatever prep you choose, know that a good prep program should be personalized to your specific needs,focusing on your area of weakness while not wasting your time covering topics you’ve already mastered.

Computing Footprints - Essay Example One of the articles had the main punch line that three sectors of economy viz., housing, transport, and food together account for 50% of household spending on the average, and at the same time account for 70-75% of climate change and often other impacts. The rest of the paper is more on the methodology side, essentially supporting this finding. This finding is valid for different countries, different cities, and even different continents. Further, it is also valid across different methodologies and in particular across the two methodologies of LCA, viz., input and output base study, which is also called the ‘top-down’ approach and process life cycle inventory database study, termed the ‘bottom-up’ approach. While both methodologies are for life cycle assessment, the top-down study is more popular. Emphasizing the differences between top down and bottom up studies, Prof. Norris explained that the top-down approach uses input and output data based on consumption. Within the input and output data base study, we compare purchasing categories. The top-down study is based on uniform data source, uniform coverage, and approach, while the bottom-up study has to combine data from different studies and methodologies.     

Collaborative writing Assignment against Euthanasia Essay

Collaborative writing Assignment against Euthanasia - Essay Example Besides, there are critical aspects of medical profession that need to be taken into consideration as far as doctor’s role in physician-assisted suicide is concerned (Jeffrey 76-8). The society put their trust on doctors as having moral responsibility of keeping the patients in state of life in line with their Hippocratic Oath. There are several arguments that attract the opposition against Euthanasia that seems real if given critical analysis. Legalizing euthanasia will create a legal loophole that can be misused by the doctors in regard to physician-assisted suicide. One such legal aspect is possible â€Å"slippery slope† from the process of euthanasia to murder. This will particularly target the poor and disabled people who may not sustain prolonged medical monitoring condition and expensive medical bills. The principle of life requires sustained help and medical support to an individual with the cardinal goal of saving life. In this respect, the aspect of socio-economic ability is not considered (Kopelman 87-9). However, in reality medical cost for some conditions requires funds which may exhaust a family and render the hospital or doctors financially incapacitated to continue offering services. For the poor and the handicap, this may compel the doctors to initiate physician-assisted suicide as a way of eliminating the cost factor. There is possible legal incentive that this doctor’s right may create to the insurance firms that may resort to termination of life with the aim of saving money. This is unfair and highly unethical in line with the common moral tenets of businesses practices and medical code of ethics. The aspect of deliberate killing of the poor and the disabled if this practice is legalized evokes the concept of Ethics which can effectively convince the proponents to think otherwise. According to Jeffrey (pg.20), â€Å"Clearly, it would be unwise to give doctors the power to issue lethal prescriptions for the

Cellular PathologyTissue Processing, Staining and Observation Essay

Cellular PathologyTissue Processing, Staining and Observation - Essay Example A staining schedule of action was put into use and this concerned the usage of ovary cell of Chinese hamster. This was done because they develop as a single layer and when ever they are kept in close vicinity there is a tendency to fuse and join together. Two very different techniques of straining were used for straining the cells. These cells were firstly worked with acridine orange and fluorescent microscope was used for viewing. In the second process the cells were worked with eosin and hematoxylin and were examined under microscope with a bright field. The entire process of staining and growth of the cells was done under a secured parameter of the Leighton tube. However, it can be mentioned that the tissues require processing for the reason that by working out the details of processing the tissues would reveal an improved amount of detail. The processing involves multiple steps that includes vital step of tissue water replacement with wax and the general format in the first stage is using the double stage. In this context the water removal process could be enumerated as the second stage and is specified as dehydration. Methol and ethanol alcohol is used in the next stages that include nucleic acids and proteins denaturing are involved along with chemical reactivity preservation with the addition molecule alteration. Shrinking comes into action with the use of alcohol and the tissues become brittle. To prevent this limited and several alcohol baths can be used with clearing agents like xylene and touleune. Specimen shrinkage can also be decreased by embedding them into resin. Embedding Centre Epoxyresin Aromatic polyhydroxy methacrylates HEMA or Glycolmethacrylate Cellulose tetranitrate or Celloidin Polyester or Ester and wax Wax soluble in water Low viscosity nitrocellulose or LVN Plastic resins Cryostat - Tissues that freezes slowly - Advanced freeze cabinet is used for freezing tissues - Thermoelectric module is used for freezing tissues. - Methods of Rapid freezing - Evaporating liquid used for freezing fast - Carbon dioxide cooling system - Cooling system with the use of frozen carbon dioxide - Liquid nitrogen cooling system While diagnosing tumours Cryostat sections are a preferable element and are a typical procedure in production of histological sections. Bright field Microscope It can be enumerated that the principal of staining is used because in general terms the larger number of tissues are basically colourless and that is the reason this method is used for identifying them. Eosin behaves at par with acidic dyes while Haematoxylin acts like a v in basic state. Both these elements tend to develop salt or electrostatic linkages with tissues that are ionized radicals. It should be mentioned that the acidophilic tissues are those who are attracted towards acid dye and on the other hand basophilic are the ones who acts with basic dyes. Haematoxylin is instrumental in staining the tissue components that are basophilic in nature and the reaction yields a dye purple. One such example is the nucleus. The reason behind this lies in the fact that the compositions are made up with acid glycoproteins, glycosaminoglycans and nucleic acids. On the other hand cytoplasm pink is stained by eosin because
