Lab report on Paper Chromatography essays

Lab report on Paper Chromatography essays 3. Materials and constituents page 5 The purpose of this lab report is to explain what exactly happened to the labs, the time that the experiment was executed and apply the results and conclusions that were deduced. Also, specify the errors that might have happened during the execution of the experiment. In the following experiment is going to be proved that a paper can separate a mixture of colours and that every colour reacts with a different way when put onto the paper strip. Chromatography is the name given to a method, which is very widely used for the separation of mixtures of chemicals and biochemicals, that depends on how fast a substance moves in a stream of gas or liquid past a stationary material to which the substance may be slightly attracted. Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. Chromatography is using a flow of solvent or gas to cause the components of a mixture to migrate differently from a narrow starting point in a specific medium. It is used for the purification and isolation of various substances. A chromatographically pure substance is the result of the separation. Because purification of substances is required to determine their properties, chromatography is an indispensable tool in the sciences concerned with chemical substances and their reactions. Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sobbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge, alterations or changes can be detected in the substance. In all chromatographic separations, there is an important relationship between the solvent, the chromatography paper, and the mixture. For a p...

Food and Its Impact on Health and Environment Research Paper

Food and Its Impact on Health and Environment - Research Paper Example The Double Quarter Pounder with Cheese: I have selected a very popular fast food item on the menu of fast food chains, the Double Quarter Pounder with Cheese. It is one of my favorite meals too but I have got to know many impacts it holds upon our health and long term living, also not to mention the impacts on animals and environment. A very popular documentary â€Å"Super-Size Me† was based upon the very similar issue. The maker of the documentary tries to gauge the impacts of fast food on his health and he goes on to eat McDonald’s meal every day three times for a period of 30 days. The impact it has on his health are enormous; he picks up a lot of fat and weight in the process. The doctors who had analyzed him said that he was also suffering from depression and anxiety and the meals had caused great damage to his heart. The documentary proved extremely shocking for many since it brought about the very true picture of how bad the impact of fast food is on our health. Composition of the Quarter Pounder: Now let’s delve into the ingredients of what makes a Double Quarter Pounder with Cheese so interesting. The double quarter pounder contains 4 oz. beef patty, 2 slices of cheese and a sesame seed bun. Well it is also served with barbeque and mushroom sauce on many occasions. The calories count is 740 which are very high on any scale in the world. Its nutrition grade is also D. The amounts of calories are predominantly fat and cholesterol. (Calorie Count) The Sourcing & Production of its Ingredients: The Beef Patty is composed of beef usually locally sourced depending upon the location of the food chains. The beef patty is composed of corn fed beef which gives it the crisp and color. A United Nations study has found that almost 18% of greenhouse gases come from the ranching and slaughtering of cows. Due to the various techniques of cow breeding and corn based feed, the beef is now much cheaper and fattier than ever before. (Ecoliteracy) The b eef processing is done by large conglomerates and a patty may contain meat form many different cows. The cows are bred in a very inhumane level and through different scientific treatments are grown bigger than their bones and body can sustain. After slaughtering, the beef is transported in its raw form to different places across the country where the beef is processed. The beef is processed in machines that bring together the mince and process them with corn to form patties. These patties are then hauled to local fast food producers where they are deep fried in oil and used in the burgers. The Cheese is very similar to this. Cows are given heavy dosage of stimulus and steroids to expedite milk production which not only causes diseases in animals but also decreases their life and may also transmit some of that in the milk too. The milk is then transported for further process where it is made into cheese and shipped to local food stores. Now a lot of fuel is being burnt in the process and global warming is one of the causes of fuel burning through transportation. On average a food related products has to travel almost fifteen hundred miles to reach to a store and this transportation accounts for about thirty eight thousand tons of greenhouse gas emission per annum. (Ecoliteracy) Health Impacts: 1 – Headaches The processed meat is contained in the burgers that is a cause of

In fact, observers say it will boast a growth rate among the highest in the world, and will eventually have the largest domestic market outside the U.S. and China. All four of the major Indian airlines are believed to be discussing aircraft acquisitions with manufacturers. The planned partial privatization of government-owned airlines is expected to provide greater impetus to future growth, Ian Thomas of the Center for Asia Pacific Aviation (CAPA) told World Airline News, but will also delay immediate purchasing plans. Airbus Industry recently gave a presentation in Delhi and Mumbai at which it presented its demand predictions for the Indian market. Airbus research indicates that the major Indian carriers will have to buy 222 airliners with 100 seats or more worth about US$7.5 billion in the next 20 years, and that fleet sizes will more than double from 112 aircraft at the end of 1999 to 236 by 2019. Scope for Airline Industry Expansion in India India's civil aviation industry will need to purchase 490 aircraft over the next 20 years, according Dinesh Keskar, vice-president for sales at Boeing. According to estimates from the aircraft manufacturer, falling ticket prices and an increase in passenger traffic will cause an increase in the demand for aircraft. Keskar told Reuters that the passenger traffic in India is likely to increase by 20% over the next three to four years. The Indian authorities have reportedly said that the domestic and international air traffic will increase by about 20% annually, due to investments from the government and private sector. The investments have been estimated at USD20bn over the next five years and the increase of aircraft numbers is expected to double the number of civilian

Environmental Impact of Aviation Essay Example for Free

Environmental Impact of Aviation Essay Today, the world is bothered by the environmental issues reverberating in different parts of the world. Part of this environmental issue is focused on global warming. As part of the whole world’s response on the important concern, laws and policies have been drafted. Some of the known environmental policies are Clean Air Act and the Kyoto Protocol. Meanwhile, the Kyoto Protocol is an agreement between different nations, mainly industrialized, adopted on December 1997 in Kyoto, Japan (United Nations Framework Convention on Climate Change, 2008). The central function of the protocol is to set a target on the greenhouse gas emission for member countries (United Nations Framework Convention on Climate Change, 2008). This is to further reduce the impending consequences of the greenhouse effect. Since the report of international scientist that climate change is worsening, all sector of the society and all nations have been invited to participate in activities primarily to help cut gas emissions. Each government of member nations also implemented programs in order to reduce the gas emission that is aggravating the global environment situation. For the past years, the reality of the phenomenon has been severally debated, even among politicians. Eventually, environment was considered as priority in the policy making. Additionally, the international concern on global warming has reached every sector, big or small, in the society. Among the business sectors, rules and regulations have also been adopted internationally in order that a standard of environmentally hazardous substances be eliminated or minimized. An example could be the non use of lead. In Europe, the Restriction on Hazardous Substances was adopted and imposed upon all its suppliers worldwide (ROHS, 2008). According to the guidelines, minimum amount of the hazardous substances should be maintained. Hence, quality of the product depends on the substances comprising the product. The environmental issue, however, is not only limited to gas emissions and global warming. Instead it covers all kinds of pollution. In the field of aviation, policies and guidelines on environmental compliance also apply. Aviation plays a vital role in transportation. It is the easiest, fastest, and more convenient means in transporting people and goods from one border to another or from nation to nation. Being an essential factor in the growth of economy, it also has an essential contribution to global warming and other environmental problems. Remarkably, the aviation contributes to various environmental problems. One of the major problems faced by aviation industry is the noise pollution being suffered by the residence nearby airports (Kutz, 2008). At present, the aviation is one among the growing business opportunities. Since new and more improved planes have been introduced, the air traffic also increases. As such, there is also intensification of the environmental concerns. The second environmental problem affecting the industry is the climate change. Climate change is the foremost environmental phenomenon that is bothering the international community. In addition, it is believed to be the cause of the drastic change in weather and the emergence of illnesses. The third major problem being caused by aviation is the poor air quality (Kutz, 2008). All these environmental concerns are mandated by laws to be addressed by the aviation industry. In the field of aviation, BAA is widely known for being the world’s leading airport company (House of Commons, et. al. , 2004). At present, it is operating eight airports namely; Heathrow, Gatwick, Stansted, Glasgow, Edinburgh, Aberdeen, Southampton, and Naples (BAA, 2008). At present, its success still continues to shine and more developments are being planned in the future. In a report propounded by the BAA for year 2005-2006, the company laid down in details the achievements and plans of each airport. Aside from that, it also presented its financial statement to show the financial operation of the company. At a glance, the company has indeed a successful and is in a stable financial status. The over-all operation and employee handling are excellent. According to Mick Temple, Divisional Director, the company recognizes the existence of the environmental issues (Temple). But, the report of BAA did not actually addressed all issue about environment related to airline or airport. In addition, the BAA presented its report in a categorical yet orderly manner. After presenting the achievements, developments, and plans of each airport, the BAA also discussed issues faced by the company. It has specified corporate responsibilities. In scrutinizing the report, the BAA did not actually address all environmental problems. As stated earlier, aviation industry is challenged by problems on poor air quality, noise pollution, and climate change. In the report of the BAA, the report laid down the corporate responsibilities of the company but in a summarized and general form. Although it has addressed all the problems cited, it did not actually specified its future plan, present programs, current status and its over-all stand on the impending environmental problems. In addressing the environmental problem on air quality, the report stated its concern on the problem that is affecting both local and national (Temple). Notably, airports around emits nitrogen dioxide and other fine particles that have negative effect on heath and environment (BAA, 2008). In addition, it has stressed on government’s declaration of Heathrow’s compliance to EU Air Quality Standard (Temple). Contributing to poor air quality, however, are M4 and M25 traffic (BAA, 2008). Likewise, the report merely added measures it can implement in order to comply with the standard. These measures include â€Å"investing in public transport, promoting alternative fuels for airport- based vehicles, and using charges to penalise aircraft with poorer emissions standards† (Temple, p. 35). However, no other reports were propounded to show that these measures have been adopted. Furthermore, the company merely reiterates its desire to review its emission while extending help to other companies with regard to the problem. As to noise pollution, the aviation is considered as one among the major contributor due to noise caused by take offs and landings? taxiing, and engine tests (BAA, 2008). With regard to BAA’s stand on noise pollution, the company has laid down its strategies in minimizing the noise. In addition, it stated its desire to work with local government, airlines, and air traffic controllers to jointly implement these strategies. First strategy is the encouragement on the use of quieter new aircraft and engine by the manufacturers (Temple). The second strategy is giving reward to those airlines using a quieter aircrafts. The fourth strategy is the improvement of compliance with quieter operating practices (Temple). The last strategy is concerned with updates of information by keeping the noise-sufferers informed better (Temple). Today, the company is doing its part in addressing the complaints of those affected by the noise of airports. Furthermore, on the most relevant environmental issue on climate change, the company proudly stressed its target of 15% reduction on its carbon dioxide emission by 2010, which is even higher than the standard (Temple). The company’s strategy is focused on energy efficiency and renewable energy (Temple). Moreover, it has also implied its adherence to Emission trading which allows business incapable of achieving the target to buy permits from those industries that are capable but only within an overall cap (Temple). At present, the company is lobbying for the recognition of the emission trading to be an acceptable mechanism in greenhouse gas emission. In addition, in its desire to reduce the impact of climate change, the company is committed in investing into new energy efficient technology, sourcing out more renewable energy, reducing emissions of vehicles in the airport, among others (BAA, 2008). Based on the above mentioned, the report of BAA may be said to have mentioned the major environmental problems faced by airlines and airports. However, it was not able to state its impact on environment. It did not also laid down the programs it has adopted to address the issue. But nevertheless, it has recognized its role in the environment. By looking into the context of the report, is can be said that the company has been unfairly assessed. It is unfair on the reason that the report presented more on the developments, future plans, and achievements of the company but did not directly addressed on the corporate responsibilities. It is true that corporate responsibility have been included in the middle part, but there is no clear stand of the company. The report stressed on the company’s plan to expand, increase passengers, intensify investment but there are no more details as to the company’s action on environmental issues. Significantly, it did not state any of its achievements in helping in the abatement of the environmental problems. It merely presented it strategies but no update has been included as to the implementation and status of the company. Interestingly, the report of the Managing Directors of each airport has concentrated on the importance of shareholders. Hence, the report was concentrated on the good sides about the company. Airports and airlines are considered as one among the places vulnerable of being attacked by terrorist groups. Notably, in 2007, Glasgow Airport has been attacked by terrorists (BAA, 2008). On that very threatening day, the company has been given an idea on the loopholes on the airport’s security. It is also of no doubt that millions of passengers and employees come in and out of the airport. In line with this, the treat of terrorism has made passenger paranoid about safety. Hence, it is but necessary that safety should be the paramount concern of the company. In response to the attack in July, 2007, the company declared its dedication in making its passengers secure. As part of its response, the company has closely worked with the Department for Transport (DfT) for guidance on its security measures (Temple). Moreover, in concurrence with the government’s standard, the company has conducted a full range review of its security systems (Temple). In order to show its sincerity in making its airports secured and safe, the company has started using technological innovations such as hold-baggage screening, new security screening and x-ray screening (Temple). In line with the company’s purpose of ensuring safety and health of its passengers and employees, policies and programs have been adopted. Additionally, according to the report, the company’s stance on security is that it is considering it as a crucial issue. Aside from its possible effect on the company’s reputation, it also recognizes its effect on passengers’ experiences. As such, the company works closely with the government agencies, armed forces, and police force in order to upgrade its security system and match with that of government security (Temple). Furthermore, it has committed itself to comply with regulations concerning safety. In accordance with this, the Health, Safety, Security and Environment (HSSE) Executive Committee have been founded with the primary goal of determining and addressing these issues affecting the company (Temple). With the growing environmental concern, some say that aviation industry is not a sustainable business. However, BAA has proven this statement wrong. In order that environmental issue be addressed and at the same time maintain or increase the profitability of the company, the company may enhance its training on environmental awareness to its employees and passengers. In addition, carbon dioxide emission can be reduced through the use of biodeisel and other alternative energy. Moreover, through reducing its flight, the company could decrease its environmental impact but can increase profit because all flights would be certainly be filled. Another measure could be on the retail sector. Since the airports are open for stores, environmental measures should also be imposed upon them. Some of the policy that can be adopted is the ban on non-recyclable things. Through this measure, all waste coming from stores would be put to recycling areas. Finally, the company could enhance its pro- environment policies despite cost on its part. This way, the cost would be repaid by the loyalty and continued patronage of the passengers. References BAA.

Tyi Wara :: Essays Papers

Tyi Wara The largest country in West Africa is Mali. Mali is bordered by seven other states. Mali is somewhat shaped like a butterfly, except that the left wing is much smaller then the right wing. The largest region of the country is the northwestern region. This region extends into the Sahara, and is almost entirely arid desert. The central region of the country is known as Sahel. Life in this region goes by the Niger River’s annual flood cycle. It has the highest amount of water between August and November. The Southwestern region of the country is more lush than the rest of the country. This is because rainfall, and rivers are more plentiful here. As you can tell, Mali’s single most important geographic feature is defiantly the Niger River. This river goes through Sahel and the southeastern region of the country. Both the Niger River and the Nile River are a major source of transportation for this country. Mali’s population consists of a number of different peoples. They are the Bambara, the Songhai, Mandinka, Senoufo, Fula, and Dogon. The majority of Mali’s people are Muslim. The official language of Mali is French. I will center in on one group of people, these are the Bambara. The Bambara people are a large ethnic group of 4 million. They are located throughout Mali, as well as in the northern areas of Cote D’lvoire, Guinea, Senegal and The Gambia. They are among the most powerful and influential ethnic groups in Mali. Most of the Bambara are farmers. Their main crop is millet. Both men and women share the farming duties. Their best known and most highly developed art form is the dance headdress. Which is in the form of an antelope. The antelope is more of an abstract design, that is sometimes in combination with human and other animal figures. These are used especially at agricultural rites. They are designed to urge the people on to produce plentiful crops. It is also to invoke the help of the spirits, by reenacting mythological scenes of the birth of agriculture. The antelope was supposed to have played a significant role in this. Two men, one wearing a male antelope headdress, the other wearing a female antelope headdress danced on the communal field. While they were doing this other young men hoed all day to mark the opening of the planting season. The appearance of the masked figures was a scared rite to honor the mythical wild creature who brought the knowledge of hoeing to mankind. The dancers were covered in long black fibers, and bent over on sticks. They imitated the cultivator, or pawed the ground like mating antelopes.

Abolitionist movement Essay

With the enlightenment and awareness of people regarding human rights came the abolitionist movement. Slavery was something that violated the basic tenet of human rights and dignity, and so it had to be abolished. Northern states have begun to pass acts which declared that all men were born free and equal. Several movements that involved religion and political movements highly influenced the strength and expanse of abolitionist ideals throughout the country. The movements that supported abolitionism varied in method and degree. Some were pacifist, as they tried to use the legal system and passed legislation seeking to make slavery illegal. Others utilized literature and the press like Harriet Beecher Stowe, the author of the famous novel Uncle Tom’s Cabin. Religious movements declared slavery to be sinful and un-Christian, to discourage believers from keeping and owning slaves. Only a minority of abolitionists used to armed revolt and instigation of unrest and anger among the slaves as the main machinery to further their cause. The movement continued its stride to abolish slavery, but its strongest anchor point came with the election of a known contester of slavery, Abraham Lincoln, as president. With the head of state holding this position of opposition of slavery, the south felt that their way of life was endangered and threatened. Economic repercussions will be felt by their planters in the cotton, tobacco and sugar farms if the hands that worked in the plantations were to be set free. The zenith of the tensions between the south and the north was the American Civil war. It broke out when the south organized and removed themselves from the control of the American government. Rise of Abolitionism Historian James McPherson defined an abolitionist as a person who has fought for the abolition of slavery in the United States before the Civil war. American abolition started early on, as there were several groups already fighting for the liberation of slaves, such as the Society of Relief of Free Negroes Unlawfully Held in Bondage, and there were several institutions which prohibited slavery already. Several states had passed laws that completely prohibited slavery in their territories. Those who joined the American Anti-Slavery Society or other groups were abolitionists. These movements were not unified, and so could not boast a unified strength. Vermont was the first territory to make slavery illegal, and Pennsylvania was the first state to abolish slavery in 1780. Then several states followed Pennsylvania’s example while some states chose to limit slave trading. Many of the states in the south retained the institution of slavery as it was the region’s life line in their plantations. Their strong adherence to the institution drove them to take a defensive stance against the rising popularity of the abolitionist movement. Many abolitionist writers distributed many anti-slavery writings and literature to the south to help spread the ideologies. Novels, pamphlets and other forms of writing began to circulate not just in the north, but also in the southern region. Southern officials were enraged at the act, and thus moved to ban all types of literature that might instigate rebellion and changes in the south. Violence was even employed to stop the circulation of antislavery media in the south. Elijah Parish Lovejoy, the editor of an abolitionist newspaper was murdered by a mob of pro-slavery southerners. His printing press was also destroyed. Abolitionists recognized the fact that slavery needed to be abolished everywhere in the country, but the north cannot interfere with the affairs of the south because of federal ruling. Because of this, many abolitionists focused on liberating the north and skipping the southern states. Some abolitionists were frustrated and did not like this idea, as they believed that every state should be free of slavery. The movement was further fortified by the support of free African-Americans and their church. With the issue of the constitution, the American Abolitionist movement split up into two groups, the Garrisonians, led by William Garrison and Wendell Phillips and another camp led by Spooner and Gerrit Smith. The Garrisonians believed that the constitution promoted slavery while Spooner’s group believed the constitution to be antislavery. Since slavery was unconstitutional, it could be abolished with the blessing of the law. More divisions in the abolitionist movement arose, but because of the social classes of the abolitionists themselves. The artisans and elites divided themselves on the issue of slavery as well. The Underground Railroad was used as a venue by many abolitionists to become more active in the cause for abolition of slavery. Many of the fugitive slaves were illegally transported away from their masters to be free men via this rail. But the railroad was made illegal by the passing of the Fugitive Slave Law of 1850. But this did not stop the abolitionists from providing shelter and transporting slaves to freedom. After the Emancipation Proclamation of January 1, 1863 was done, many abolitionists moved to liberate slaves in the slave states. There were also movements to improve the social and living conditions of African-Americans all over the country. The Thirteenth Amendment finally ended all slave subjugations in the country.

Essay on Cell Phones

Essay on Cell Phones Essay on Cell Phones This is a free example essay on Cell Phones: When I was born, in the mid 80`s, cellular telephones were just becoming popular as a wireless way of communication. But the concept caught on rapidly and people were subscribing left and right for cellular phone service. As I was growing up I began to notice more and more people around me beginning to use these new marvels of technology. I was in a state of awe about how these contraptions, which at the time were not so little; some of them so large as to have to be carried in a bag and some the size of some of the biggest house phones today, really functioned. I was in disbelief about just how you could actually take a telephone with you wherever you go and be able to talk to people on it whenever you wanted. When I was about six or seven I felt as if I was going to go crazy if someone in my family did not own one of these new contraptions, when finally the day came. I had taken a trip to Huntsville with my mom and my sister to go shopping one afternoon, we were starting to finish up our adventurous day of shopping when all of the sudden my mom walked into the Bellsouth Wireless store. My eyes glowed with excitement as we walked in. Finally, after what seemed like days of talking with salesmen about different calling plans and such, we had our very own cellular phone. When we got to the car, I frantically begged to look at the phone and all of its wonder. On the trip back to Decatur, I pressed the buttons on the phone, listened to funny sounds that it made, and sat in glee holding the mobile piece of technology. Finally the time came and my mom made the first call on it, calling back to my house telling my father the wonderful news of the new gadget, and after asking until I couldn`t ask anymore I finally got to talk on it and enjoy its wonder. Since then, over the past years, my parents have had many new phones of all shapes and sizes and colors. Over the years phones have gotten smaller, more compact and convenient and better technologically to suit our eve ryday lives. Some cellular phones are now as small as business cards, some phones being a brilliant light show of blinking, spinning, flashing L.E.D lights, and some phones basically being a little P.C. that fits into your pocket. Unfathomable amounts of time, money, and research going into these little devices of communication just to try and make our lives a little bit easier. People spending their lives making all of the electronics and technology going into these devices being made smaller and faster and better.
