Air Pollution
Air pollution Here?s a little introduction to this project. There are always two ways to look at something. There is the good way, which in this case would mean looking at all the positive effects that human intervention has created, These are very few if there are any at all! Also, there is the other way. This would be the bad way consisting of basic criticism of all the negative effects that human intervention has caused. These are quite a few and therefore we shall talk about them. Fortunate

Acid Rain Introduction: What Causes Acid Rain? One of the main causes of acid rain is sulfur dioxide. Natural sources, which emit this gas, are Volcanoes, sea spray, rotting vegetation and plankton. However, the burning of fossil fuels, such as Coal and oil, are largely to be blamed for approximately half of the emissions of this gas in the world. When sulfur dioxide reaches the atmosphere, it oxidizes to first form a sulfate ion. It then Becomes sulfuric acid as it joins with hydrogen atoms in

Air Quality Air Quality & Dispersion Today, the air quality aspect of ARL research is by far the dominant theme, but distinctions among the themes remain somewhat vague. For example, the models developed for emergency response purposes are among those used for air quality prediction. The Air Quality and Dispersion theme is one of the strongest ties that binds ARL's components together. ARL is not heavily involved in the pure science of the business. Instead, ARL focusses on the need to assemble

The Haber Process
The Haber Process 1. The Haber Process During the first decade of the twentieth century the world-wide demand for ammonia for use in fertilisers (in the form of nitrates) and in the production of explosives for use in mining and warfare could only be satisfied on a large scale from deposits of guano in Chile (2). Though this deposit was of huge size (approximately five feet thick and 385 kilometres long) it represented a rapidly depleting resource when compared to world-wide demand. As a result

Bacteria Are Often Maligned As The Causes Of Human And Animal Disease
Bacteria are often maligned as the causes of human and animal disease (like this one, Leptospira, which causes serious disease in livestock). However, certain bacteria, the actinomycetes, produce antibiotics such as streptomycin and nocardicin; others live symbiotically in the guts of animals (including humans) or elsewhere in their bodies, or on the roots of certain plants, converting nitrogen into a usable form. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria help to

The Enviromnetal Degradation as a Result of Overpopulation 1 Introduction There are simply too many people on our planet, and the population is not showing any signs of slowing down(see Figure 1). It is having disastrous effects on our environment. There are too many implications and interrelationships to discuss in this paper, but the three substances that our earth consists of: land, water and air, are being destroyed. Our forests are being cut down at an alarming rate, bearing enormous impact

What Is Angina? And What Is The Cure?
What is Angina? And What is the Cure? QUESTION: What is Angina? And what is the cure? RESPONSE: Angina refers to the pain arising from lack of adequate blood supply to the heart muscle. Typically, it is a crushing pain behind the breastbone in the center of the chest, brought on by exertion and relieved by rest. It may at times radiate to or arise in the left arm, neck, jaw, left chest, or back. It is frequently accompanied by sweating, palpitations of the heart, and generally lasts a matter of

This report is an overview of each stage of the treatment of sewage. I have included a diagram of a typical sewage plant.

The wastewater then passes through a

Sir Humphrey Davy In Chemistry there are many very important chemists. One is Sir Humphry Davy. Davy was born on December 17, 1778 in Penzance, Cornwall, England. He went to school in Penzance and in Truro. In 1794 his father died, to help his family financially he got a job as an apprentice to a surgeon. The surgeon's name was J. Binghan Borlarse. In 1797 Davy became interested in Chemistry. So in 1778 he became superintendent of the Medical Pneumatic Institution of Bristol. This organization

The Lake Tahoe area was even in the spotlight for the winter Olympic Games at Squaw Valley in 60's. Over the decades we have learned, by mistake, what needs to be done to protect the lakes' beauty and character. The lake is foremost known for its color and clarity, and has been capitalized on for these qualities. However, upon enjoying the lake and creating a touri

Allergies
Allergies An allergy is an abnormal reaction to ordinarily harmless substance or substances. These sensitizing substances, called allergens, may be inhaled, swallowed or come into contact with the skin. When an allergen is absorbed into the body it triggers white blood cells to produce IgE antibodies. These antibodies attach themselves to mast cells causing release of potent chemical mediators such as histamine, causing typical allergic symptoms. A person who has allergies doesn't have a poor im

The number of livestock animals produced in the United States has grown modestly in the past two decades, but the number of farms raising them has slunk dramatically because large producer now dominate the market. The large increase in industry farming has led to large quantities of manure. B. Problem Definition The over abund

Introduction
Introduction In the pond water lab experiment, our group has chosen to test the effects of nitrates on a pond community. After a lot of research, we have found that nitrates in a pond community can increase growth rates of plants and some animals. The effects of nitrates include algal blooms, which is when too much food or nutrients are consumed by producers, (i.e. algae) causing them to grow and spread, so they consume all of the dissolved oxygen in the water. Most animals in water like many ki

Brisbane River 1.0 INTRODUCTION The Brisbane River has flowed for over 400 million years. The catchment of the Brisbane River has overcome phases of flood and drought while its origins altered as the surrounding land changed overtime. In 1823, John Oxley entered the river for the first time. At the time the river appeared clean and unpolluted. Oxley immediately recognised the rivers potential as a site for new settlement, through his recommendation the city of Brisbane was established in 1825.

Cryptococcus Neoformans BackgroundThe organism C neoformans is an encapsulated yeast; its environmental niche has not been completely defined, although outbreaks of disease have been associated in particular with pigeon roosts and other large contaminated sites. There are two varieties of C neoformans, distinguished by antigenic differences in the outer capsule of the organism: serotypes A and D (C neoformans var neoformans, the most common strain) and serotypes B and C (C neoformans var gatti).

As the population continues to grow and the earth gets more and more crowded with people and their waste it becomes a major issue of whether there will be enough space on the planet earth for future generations and their waste (trash) too. When first beginning to collect trash and and counting the trash my attitude was - what influence could my family make? But a
