Mother Nature Knows Better in Chemistry Essay

Each and every one of us has a responsibility to protect our environment. Being thinking beings, we have all that it takes to keep our surroundings free from abuse and misuse. All we really need is to know what we do right and which actions we do wrongly to help lessen the effects of modernism to our planet. The history of life on earth has been a history of interaction between living things and their surroundings (Carson 420). Mother Nature is wise. Although all creatures have been given the proper habitats and basic needs to live, earth also provided organisms that would limit each species’ reproduction so that a healthy balance is acquired. This equilibrium has given peace on earth until man had learned to use his mind to alter his environment. The want for a better and comfortable life has always been man’s weakness. This has been the reason why history shows that different cultures have tried to get the best of other worlds into their own lands. Plants and animals have been imported by different countries to adapt these creatures to another culture’s different needs. However, this has destroyed the balance that nature had intended and has resulted to negative effects such as the transportation of unneeded microorganisms. Carson explains that each organism has counter creatures and aspects in its natural habitat that limit its population to the number that is needed to balance the environment it belongs to. Whenever an organism is transported to another place, there is no guarantee that the new habitat will be able to control its population. This, therefore, can become a threat to its new environment in the form of pests or even epidemics. Another reason for imbalance is the farming system that has been developed. When more than the normal quantity of crops are planted in just one place, the insects that are attracted to these also grow in abundance. Therefore, upsetting the natural balance of the environment causes problems like pestilence. Urban lifestyle has also contributed to the problems of insect infestation. In some countries, the natural habitat has been interrupted by the build up of too many houses (and slums) in just a particular piece of land. Irresponsible disposal of garbage and unhealthy habits also give rise to the problem of mosquitoes and other pests. Dichloro-Diphenyl-Trichloroethane (DDT) has been the first synthetic pesticide that was ever invented to control infestation. Carson believes that this chemical and the other man-made pesticides leave particles on the areas that have been treated and this harms the other parts of the environment. This has become the premise for the invention of chemicals that will counter attack the problems of insects. The term â€Å"chemical† is defined by the Oxford Dictionary noun a distinct compound or substance, especially one which has been artificially prepared or purified. Being man-made, it can destroy the balance of nature. Modern society has a wide inventory of many chemicals that can be harmful to the environment. Some of these such as hair sprays, cleaning aids, smoke from cigarettes and cars, etc. do not seem harmful but researcher say otherwise. DDT has even been ascribed as a factor that leads to cancer. Ronald Bailey (427), an environmental reporter, believes that DDT has been falsely accused of being a carcinogen because research cannot prove that it really does cause cancer. However, environmentalists like Rachel Carson have ignorantly used this premise to increase awareness for our planet. Whether or not DDT is a carcinogen, it is just one of the synthetic materials that have come to dominate human living. Thousands of other inventions using chemicals have brought forth many problems that are not just harmful but also irreversible. Global warming, based on Encyclopaedia Britannica, is an increase in global average surface temperature resulting from an increase in the amount of carbon dioxide (caused by natural emissions of plants and combustion from carbon-containing materials), methane (produced industrially by the destructive distillation of bituminous coal in the manufacture of coal gas), and certain other trace gases in the atmosphere. Industrial emissions and smoke belching automobiles are being blamed for this phenomenon. This has caused a lot of controversy because it means that the earth is becoming too warm for human existence. However, according to climate scientists, human activities have very little effect on the climate, compared to many other factors, from volcanoes to clouds. (Sowell) Global warming is just an issue being used by other scientists to get grants for their studies. These researchers claim that with or without man’s inventions, nature has its own causes of global temperature changes. The truth in the many arguments about what civilization has done to the environment is hard to decipher for common students. However, whether or not pesticides are carcinogens and even if global-warming is a doubtful issue, our environment is a very important place that all must protect from abuse and misuse. Pesticides may not be immediately fatal for humans but to comply with universal laws, there is a need to use these in moderation. Anything overdone can lead to serious consequences such as food poisoning and allergies. Industrial wastes, even if they apparently do not really affect global-warming, can still cause pollution that leads to many health issues. The earth is the only home for us human beings. It is where we get our food and breathe the air that we need to survive. It provides us with the shelter we need to protect ourselves from the harsh realities of our own habitat. We need to find ways to start ensuring the safety of our environment against man’s drive to improve lives by ignoring possible negative consequences. The European nations are a model right now for environmental protection. Car companies need to recall their older less-functional models so that these can be recycled into new products for their later models. Other electronic gadgets like personal computers and mobile telephones are also being eyed for this project. Forced to recover value from their discarded consumer goods, companies will have a strong incentive to design the toxics out of their products and to make them easier to disassemble and remanufacture (Greider 3). As students, there are many ways that we can also help protect the environment. Proper garbage disposal not only makes places look neat but also drive away the possibility of diseases that are brought by the insects that get attracted to garbage. Maintaining electrical and mechanical gadgets according to manufacturer’s advice also ensures that these are performing safely instead of emitting probable poisonous discharges. Reporting to authorities regarding the incidences of environmental abuse or misuse can also bring solutions to possible harmful situations. It is often said that the roots of environmental destruction lie in treating natural resources as â€Å"free† and not giving them â€Å"value. ’ (Shiva 443) Each little creature on earth serves a purpose for Mother Nature in balancing our environment. It may be hard to understand the impact of our small actions but putting value to the environment can make big changes that can only be seen collectively in the future. We have our own place in this natural balance and it is our responsibility to find the ways to maintain this balance.

Difference between women now and centuries ago Essay

Women are important asset in one’s life even if you are living in the 1800’s, 1900’s or nowadays. The difference between women living years ago and now might varies, such as cultural, social, and fashionable differences. Have you ever wondered what women’s role in life was? Well this depends on the perspective of the person whether a male or a female, it also depends on the time zone. At various time throughout history, working women were viewed as cruel and not devoted to help their children and family. This is wrong; women should develop, gain rights, and become more independent because ignorance kills the identity of a person. What’s the difference between women’s life nowadays and before? Men considered women in ancient societies to be only wives who cook, and take care of their house and children; on the other hand nowadays men look at women as a respectful hard worker and an important asset to our society. Examples of change, women in ancient societies were forbidden to vote. Yet, a brave woman Lydia Taft was courageous enough to be the first women who breaks the rule and vote , after this courageous act New Zealand decided to allow women to vote , since then women made a great change and made their rights approximately equal. Women in the earlier centuries were not allowed to be sociable, they were not allowed to walk on the streets alone or even travel alone, and on the other hand women recently are free to do whatever they like. Even marriage has different aspects many years ago women didn’t have a choice who to marry or to see his face. Marriage took place through tribal processes and father’s decision, but Nowadays women might marry without even caring what her parent’ point of view. This gave the freedom of choice, and by this way less family divorces will occur. Job opportunities for women differ from back then and now. What comes in mind when someone first asks you what is the gender of an engineer instantly what comes in mind is a man. Nowadays this all changed women have many unlimited opportunities in jobs. They can get paid sometimes more than men, they can now run companies, and unlike many years ago their best job is to be teachers. Another aspect is their clothing. Women were extremely cautious when it comes to what to wear. Back then it was rude to wear like nowadays small skirts, Shorts that show thighs, and much more. Education plays an important role to portray how women nowadays differ than women lived centuries ago. Education back then was only offered to men, this lead huge inequality between sexes. This made illiteracy rate high and affect the society negatively making only one brain in the family working rather than two brains. Education is the core of life. Nowadays education is a must and societies are in a good shape due to both sexes educated. Due to the publisher Cox, Matthews & Associates, Inc., from a journal of an unknown author, his point of view stands with that education for women is a vital role that has high opportunities unlike women that didn’t get educated centuries ago. â€Å"Many of us here at Diverse have been privileged to meet dynamic women in the world of higher education and beyond. They lead some of the most demanding and consequential organizations and programs on the planet. No longer sitting on the decision-making sidelines, they have shattered the glass ceiling and, subsequently, have introduced new ways of thinking about and approaching leadership.† Women that are recognized and entered history books will always be praised and remembered as heroes; unlike women living centuries ago that are illiterate. Example from Belle S.Wheelan , president of the accrediting body since 2005, it also means â€Å"Students Are Central to Success,† a fitting description for what motivates her on the job. Wheelan is the first African American and the first woman to lead SACS.† Women struggled a lot in the earlier centuries, but as time passes everything changes. Women achieved a lot and made it into the highest rank in over society. A wise man once said â€Å"Every brave warrior was once a defenseless baby and every building was once a picture it’s not about where you are today but where you’ll reach tomorrow†.

Julia’s Food Booth

(A) Formulate and solve an LP model for this case The objective here is to maximize the profit. Profit is calculated for each variable by subtracting cost from the selling price. The decision variables used are X1 for pizza slices, X2 for hotdog, and X3 for BBQ sandwich.X1 (pizza) X2 (hotdog) X3 (sandwich) Sales Price 1.50 1.50 2.25 Cost 0.75 0.45 0.90 Profit 0.75 1.05 1.35*For Pizza Slice: Cost/Slice = $6/8 = $0.75 cost per slice Maximize Z = 0.75 X1 + 1.05 X2 + 1.35 X3 Constraints: Budget: 0.75X1 + 0.45X2 + 0.90X3 ≠¤ 1500 Oven Space: 24X1 + 16X2 + 25X3 ≠¤ 55,296 in2 The calculation for the oven space is as follows: Pizza slice total space required for a 14 * 14 pizza = 196 in2. Since there are eight slices, we divide 196 by eight, and this gives us approx. 24 in2 per slice. The total dimension of the oven is the dimension of the oven shelf, 36 in * 48 in = 1728 in2, multiplied by 16 shelves = 27,648 in2,  which is multiplied by 2, before kickoff and during the halftime, giving a total space of 55,296 in 2.(B) Evaluate the prospect of borrowing money before the first game. The shadow price or dual value is $1.50 for each additional dollar Julia would increase her profit, if she borrows some money. However, the upper limit of the sensitivity range is $1,658.88, so she should only borrow $158.77 and her additional profit would be $238.32 or a total profit of $2488.32.(C) Evaluate the prospect of paying a friend $100/game to assist. Yes, she should hire her friend for $100/game for it is almost impossible for her to prepare all the food in such a short time. In order for Julia to prepare the hotdogs and barbeque sandwiches she would need the additional help. With Julia being able to borrow the extra $158.88 she would be able to pay her friend.(D) Analyze the impact of uncertainties on the model.The impact of uncertainties such as weather (to sunny, rainy, or cold), competition, increase in food cost, and the attendance at each of the six games could r educe the demand for the items sold by Julia. If it is raining or cold then there may not be as many patrons at the games and if it is to hot people may not want to eat before or during the games. The higher the uncertainties the demand shifts, therefore the solution of the LP model will change and so does her profit. She will not be able to produce a $1000 profit under high uncertainty.

It has to be a article on english language learners Essay

It has to be a article on english language learners - Essay Example The article pointed to some literature about semantic processing between monolinguals and bilinguals and the assumption that bilinguals are as adept as monolinguals when it comes to conceptual processing of tasks such as picture naming. The study conducted an experiment by recruiting 31 English-speaking monolinguals and 31 Spanish English bilinguals from the University of San Diego. One hundred eighty pictures were shown to the participants to determine which group performed better at naming pictures. The method for interpreting the data used ANOVA analysis. The authors proposed that bilinguals primarily differ from monolinguals when they name pictures in their dominant language due to the â€Å"degree of experience that they have had with picture names particular to that language† ( p.8). Nevertheless, the study is not that conclusive since repetition and attenuation must be thoroughly considered in further experiments. In conclusion, the author’s ideas may be considered by early education teachers of the English language to bilingual students . This study can be helpful in understanding the learning needs of bilingual students specially those who belong to marginalized groups. There is no need for a change in policy but a better orientation for English teachers. I highly suggest that this study be a required reading for English teachers so that curriculum would be attuned to the needs of the learners. The second article is titled Assessing the Advantages of Bilingualism for the Children of Immigrants1 by Tanya Golash-Bolza. The article was published in the journal Internal Migration Review in 2005. The purpose of the study is to : â€Å" examine whether or not children of immigrants in the United States benefit from being bilingual. These analyses reveal whether there are costs to resisting linguistic assimilation or if it makes no difference at all so long as students attain English proficiency. More specifically, this study addresses whether

Racial Profiling on Drug Warfare Essay Example | Topics and Well Written Essays - 2000 words

Racial Profiling on Drug Warfare - Essay Example However, one can recognize the modest changes in white racist domination in the United States without downplaying the strong relationship between being black and being a target of serious racial discrimination. In one way or another, all black Americans and Caucasians continue to suffer discrimination because white domination of black Americans and other people of color remains a major organizing principle for group life in the United States. According to statistical results "Although African Americans comprise only 12.2 percent of the population and 13 percent of drug users, they make up 38 percent of those arrested for drug offenses and 59 percent of those convicted of drug offenses causing critics to call the war on drugs the "New Jim Crow" (Race and the Drug War n.d.). The racial hierarchy is supported by a range of dominant-group prejudices and stereotypes, yet it is perpetuated most centrally by the discrimination carried out by many whites on a recurring basis. Age-old pattern s of racial inequality-of unjust enrichment and unjust impoverishment-are reproduced by the daily routines of antiblack discrimination. For instance, "During the height of the war on drugs, from 1986 to 1991, the number of white drug offenders in state prisons increased by 110 percent. The number of black drug offenders grew by 465 percent" (Shaw 2000). Police pays a special attention to African-Americans and Caucasians because of ethical differences and stereotypes. It should be no surprise then, that African Americans are often depicted as criminals in mass media. Crime in America is often portrayed in blackface, seemingly suggesting not only that African Americans and Caucasians are likely to be involved in crime, but that they are responsible for most of the crime in America today. "Racial profiling is the law enforcement practice of substituting skin color for evidence as grounds for suspicion" (Race and the Drug War n.d.). Contemporary patterns of discrimination are grounded in the benefits that whites have historically secured. All forms of racial discrimination transmit the legacy of the past, that of slavery and legal segregation. Today discriminatory practices reproduce and reinforce the unjust impoverishment and enrichment of the past. Discrimination also reflects and perpetuates the age-old racist ideology, with its asso ciated array of anti-black images and attitudes. When blacks and Caucasians encounter whites in a broad array of contemporary settings, they often meet negative beliefs about their abilities, values, and orientations. Racial barriers persist today because a substantial majority of whites harbor anti-black sentiments, images, and beliefs and because a large minority are very negative in their perspectives. When most whites interact with black Americans at work, in restaurants, on the street, at school, or in the media they tend to think about the latter, either consciously or unconsciously, in terms of racist stereotypes inherited from the past and constantly reiterated and reinforced in the present (Daum 65). Police may actively persecute blacks, or they may engage in an array of avoidance behaviors.

Skip navigation links BFS 3440-07B BUILDING CONSTRUCTION FOR FIRE PROTECTION (BFS3440-07B) - Essay Example The frame is a structure that holds the sprinkler components together .The frame styles may be of low profile, flush standard as well as the concealed amounts. The frames types depends on the areas that should be covered, type of hazard to be protected and the visual effects that may be required. Thermal linkage controls the release of water from the sprinkler systems. The linkages hold the cap in the right place and prevent water from flowing out of the pipes. (Wallace, and Webber, 2004, p. 285). The function of the cap is to provide the water tight seals over the sprinkler orifices that are held in place by the thermal links. In case the thermal fails to function, the cap is released and water finally flows from the orifice. Orifice refers to the opening in the water pipes at the base of the sprinkler valve. The opening in the water pipe is at a place where the water comes from which is about half an inch in diameter .It varies from the larger hazardous areas to smaller ones in the sprinklers systems. The detector is used in splattering the water streams from orifice to the pattern that is efficient for suppression of fires (Wallace, and Webber, 2004, p. 285). It is therefore important for all organizations to install the sprinklers systems within their organizations so as to protect themselves as well as their organizations from fires. Sprinklers are of different types, and therefore should be used as per their
