The issue of the pollution of the environment has been an issue that has always been addressed in different forums. This is mainly due to the fact that the continuous pollution makes the world less inhabitable for man. Pollution may be on different components of the earth; from water, to air to the ground itself. Various mechanisms have been developed as a way of ensuring that we are able to conserve the environment (Shaw 14). These may include measures like ensuring that the citizens use biodegradable products in order to prevent the instances of soil pollution, or ensuring that ...

Hit and run homicide

A hit and run are normally defined as being involved in a vehicle accident with either a pedestrian, another vehicle or an object and escaping from the scene without being identified or give any assistance to those in need. It is mostly defined by leaving the scene whether you caused the accident or not. However, if you return to the scene maybe you had gone to access emergency assistance will not be considered as a hit and run. In a hit and run accident, there are several wound and injuries that are common and they assist in reconstructing the ...

Relationships between society and nature have become much more complicated in the conditions of scientific-technical progress. People received the opportunity to influence the course of natural processes, have subdued the forces of nature, began to master almost all of the available regenerative and non-renewable natural resources, but to pollute and destroy the environment. Air pollution has remained the major problem in the modern society. It is defined as the introduction by man into the environment of substances or energy liable to cause hazard to human health, harm to living resources and ecological systems. (Tiwary, Colls, & Colls, 2010) Artificial (anthropogenic) ...

Is Climate Change Caused by Human Action

Introduction Are humans responsible for climate change? While it is evident that climate change is a result of different factors which when combined produce a hazardous effect, human action is considered to be the main cause of global warming. Numerous studies show that various human activities produce gas that traps heat which results in most of the increase in globally averaged temperatures. Clearly, atmospheric warming and cooling did not begin with people. It used to occur long before the rise of humankind through natural activities, such as volcanic eruptions, changes in the sun’s intensity and the already existing ...

I humbly appreciate this opportunity to address this congregation at the 10th Annual Environmental Protection Agency’s meeting [Acknowledge any VIP in the audience]. Warfare is a great deterrent to the attainment of sustainable development. How can the future generation meet their need if the needs of the present generation are not assured? [Pause for a few seconds]. Each time war breaks out between nations, the negative impacts are leveled on the natural resources and consequently, on the environment. [Refer to slide for the main triggers of these wars]. It is interesting to note that war has been an ...

Introduction

Air pollution as the name clearly suggests, refers to the accumulation of particles or impurities in the air composition. These particles could be dust, smoke, burnt fuel like diesel or petrol, and other burnt components. Air pollution, particularly in China, is a major problem or bottleneck that is more often than not ignored at the risk of the people’s health as well as that of the economy. Major health conditions especially, respiratory conditions like asthma, bronchitis and other perilous conditions like cancer could spell doom for the people of China (Ho, and Chris 115). Measures to curb the ...

Synopsis:

I witnessed the body of a victim lying supine on an outside deck on arrival to the location of the reported shooting. From observation, it is evident that the victim is an elderly man since he has grey hair. The victim is dressed in a blue jacket (that is zipped up past the halfway point), blue shirt, and blue pants. The victim is wearing wire-rimmed silver glasses with blood spatter on the left lens. Closer examination of his face reveals that there are numerous evident blood spatter patters below his nose on his upper lip, chin, and upper left ...

Question 1

PCBs Polychlorinated Biphenyls (PCBs) are chlorinated hydrocarbons with two phenyl rings. They are stable, resistant to fire and possess good insulating properties. Hence, they were used widely before their ban in 1979, in transformers, capacitors, hydraulic machine lubricants, and oil based paints, adhesives, sealants, insulating and caulking material as well as in light ballasts. (US Environmental Protection Agency [USEPA], 2013). EH&S as well as FS personnel would have to handle PCBs when they indulge in building demolition, renovation, decontamination activities or in case of emergencies such as fire and explosion. PCBs present in electrical and building materials pose a ...

In George Bernard Shaw’s Pygmalion, Eliza Doolittle is initially nothing but a poor girl selling flowers on the street. Due to her incidental presence of Higgins and his bravado in discussing his abilities with Colonel Pickering, Eliza is swept up into a world that she would have been unable to touch without the help of Henry Higgins. Eliza speaks with a Cockney accent, making her incapable of breaking into the more refined world that she dreams of; Higgins takes her in and transforms her into a completely different woman. The transformation is that Eliza goes through not on the adoption of refined ...

Carbon (C) is a chemical element of atomic number 6 and belongs to group 14 on the periodic table. Carbon is a nonmetallic element and it’s the sixth in abundance in the universe. Coal is the most readily available source of carbon. Carbon in its raw form is of little value and has to be processed into commercially applicable forms. Commercial carbon appears in three allotropes: graphite, amorphous, and diamond. This is a research paper on carbon, its applications and negatives effects on the environment (Jefferson Lab).

Memorandum 2 This is a business memorandum in response to your memorandum regarding the selection of a proper boiler for our Salt City property. I am very glad that your proposal to upgrade the heating system has been approved, as it is in dire need for a superior boiler. The current heating solutions installed at Salt City make us of water boilers, which use obsolete technology. This is the reason of frequent customer complaints and inefficient heating at lower temperatures. As I have mentioned in my previous memo, we can make use of the water tube heating or ...

Environmental impact of aviation arises from emission of noise from aircraft engines and gases which are released. These gases contribute greatly to global dimming and climate change. Despite the efforts of reducing emissions from automobiles and using less polluting turboprop and turbofan and more fuel-efficient engines, the continuous rapid development of aircrafts contributes largely to the total pollution involved in aviation. This has led to a heated debate about introducing high taxation of travelling by air and including aviation in a scheme of emission trading to ensure that all external costs involved in aviation are considered. This paper talks about environmental ...

Introduction

The problem of air and water pollution has been a great concern not only to the people of New Jersey but throughout the world. This has been a problem to the whole world for the past over a hundred years and it still remains a challenge today though several efforts have been made to curb it. From the period of the second half of the 20th century several countries including the United States have tried to come up with certain rules and regulations to help reduce the level of pollution. The United States through the United States Environmental Protection Agency have come up ...

John A. MacDonald was the first prime minister of Canada. His policies were focused in growing the country politically, economically and physically. His wish for a bigger nation that was independent economically was not easy considering the other bigger and stronger nations that surrounded Canada. Furthermore, Canada was under the leadership of Britain which made it quite challenging for any leader to make and implement any laws. However, this did not hinder MacDonald from achieving his dream of better Canada. In his national policies, he still considered Britain to be its great supporter and in fact engaged the nation to ...

Literature Review

Abstract This literature review paper focusses on the subject of the role of dreams and the relationship between those dreams and hope. For this purpose three readings of different genres have been selected, to see what and how the three writers have expressed their dreams. The three pieces of literature under study are, a poem called ‘The Chimney Sweeper’ by William Blake, Martin Luther’s speech ‘I have a dream’ and the speech by Abraham Lincoln, popularly known as the ‘Gettysburg Address’. ‘The Chimney Sweeper’ by William Blake addresses the issue of child labor and the social oppression that a ...

Childhood was a markedly different experience during the Romantic period than it is today. Whereas there are myriad laws in place to keep children safe from abuse inside and outside the home, and free from the burden of work, in the time of the Romantics, children were simply seen as little adults, with much higher expectations on them. For example, when Charles Dickens was twelve years old, his father, mother, and younger siblings were all thrown into prison because of debts that Dickens’ father had incurred. Dickens was not imprisoned, because it was his responsibility to earn the money that ...

Disturbing trends in the climatic condition of the Arctic led to scientists researching this area. Upon close scrutiny the fascinating greening of the Arctic has been observed. From the space, using Normalized Difference Vegetation Index (NDVI), which is an index of vegetation greenness, the circumpolar changes in the tundra vegetation are observed. The NDVI records of the last 29 years were gathered and the Maximum NDVI was derived. According to studies the MaxNDVI was usually observed in August due to many factors such as CO2 fluxes, above-ground biomass, total eco-system production etc. Many other biophysical properties also cause the ...

Gasoline and Diesel are both derived from petroleum. This is done by heating petroleum so that different components boil at different temperatures. The other products of importance obtained from this process are propane, bitumen, kerosene, etc.

Gasoline is made up of various constituent compounds. The chief constituent is Isooctane (IUPAC name: 2,2,4 – trimethylpentane). Its chemical formula is C8H18 and undergoes combustion according to the following equation.

Gasoline is very volatile liquid (more volatile than diesel). It is very stable. It can be stored indefinitely under proper conditions (Reduced air exposure, cool temperatures, etc.). It has a relative density ...

Introduction

Fire is described as the visible result of an oxidation process in the chemical reaction known as combustion. Combustion occurs between an oxidant (source of fuel) and oxygen which results in the release of heat and the source of fuel being converted into another form (Grimwood et al., 2010). When heat is released, light is produced either as a flame or glowing. The fuels which bring about combustion are mainly organic compounds like hydrocarbons which may be in the solid, liquid, or gaseous phase. The part of the fire which is visible is known as the flame. It is ...
