Abstract
Mosquitoes are insects that have been around for approximately 30 million years. Mosquitoes can sense carbon dioxide and lactic acid up to 100 feet away. If a person wears light or white clothing, mosquitoes can see him/her and zero in on him/her. Mosquitoes can detect heat. One way to stop mosquitoes is to confuse their chemical receptors.

Abstract
Dioxins and other chemical components have been located in foods that people consume everyday. Too much dioxin can be fatal and/or pose serious threats to newborn children in terms of birth defects. What has been done to diminish this chemical toxin in foods? Government officials have developed policies in an effort to control contamination in terms of pesticides, feeds for livestock and water treatments. If preventions are not implemented more readily, these chemical toxins will pose significant elevations in diseases in humans and animals through contamination.

Abstract
This paper questions what chemicals and preservatives have been added to make our tomatoes especially red or our various fruits especially succulent and fresh even after months of sitting on a supermarket shelf. The paper argues that pesticide use should be cut back dramatically in America because of the dangers they present to human health and the dangers they present to the environment - even though, admittedly, pesticides are useful at eliminating destructive pests and can certainly boost food production.
From the Paper
"We are all prone to wonder: what is really in the food we eat? In other words, what chemicals, what preservatives, have been added to make our tomatoes especially red or our various fruits especially succulent and fresh even after months of sitting on a supermarket shelf? It is a fair question and it is one that more Americans should be asking. With that in mind, this paper will argue that pesticide use should be cut back dramatically in America because of the dangers they present to human health and the dangers they present to the environment - even though, admittedly, pesticides are useful at eliminating destructive pests and can..."

Abstract
In this article, the writer discusses the use of pesticides in agriculture in California and examines whether pesticides should or should not be used, noting that pesticides have been used for decades as a way of eliminating certain pests in order to protect crops, though many critics have also emerged to call for stopping the use of pesticides because of various perceived dangers. The writer discusses that organic farming has developed as a response, meaning farming which does not use pesticides or other additives so that the food produced is free of such added substances. The writer maintains that arguments can be made on both sides, though the clearest argument can be made for the judicious use of pesticides in order to protect crops while not harming the consumer, with great care taken through testing and monitoring to assure that the pesticides used do no harm.

Abstract
This analytical paper looks at the outline of chemistry within pesticides. Using a chronological approach to creation and use of pesticides, the writer provides a look from the making of DDT onwards. The writer provides an overview of the main pesticides used and their toxic effects on the environment. In addition, the writer ties these use and development of pesticides into the development of the EPA. In the conclusion, the writer argues that users of pesticides should research the pesticide in depth and apply them properly to their specific use.
From the Paper
"There are several different types of pesticides, and their toxic effects and mode of action all differ. First are the Organophosphate pesticides, which are compounds that act on the enzyme acetylcholinesterase. They contain phosphorous, and they act on the nerve actions of the insect. They attack the enzyme, destroying nerve function, which is necessary for life. Eventually, the pest dies from respiratory failure. One example of an Organophosphate pesticide is Malathion, which is used to control mosquito and Mediterranean fruit fly.
"Carbamates are another type of pesticides that cause cholinesterase inhibition poisoning by affecting the same enzyme acetylcholinesterase that Organophosphates effect. However, they inhibit the enzyme, rather than attack it, and they are less powerful than the previous group of chemicals. It is interesting to note that Carbamate compounds also exist in polyurethanes, although in far fewer numbers. One type of Carbamate is Sevin, used in agriculture and other applications around the world. It is also banned in several countries because it is highly toxic to a number of species.
"Organochlorines are pesticides that include chlorine as an ingredient, along with carbon and hydrogen. These pesticides attack the neurons by opening sodium ion channels in them, which causes them to fire continually, which causes spasms and then death. One of the most well known of the Organochlorines is DDT, which has been found to be extremely toxic to humans and other animals besides pests, and is known to linger in the environment for years, leading to continuing poisoning of other animals, which led to its ban in the United States in 1972. Many other Organochlorines have been banned, as well."

Abstract
This paper discusses that science has proven that pesticides pose two separate yet related dangers. The writer notes that pesticides are everywhere in our environment and that children especially are exposed to them every day in their food and in the surfaces they touch. The writer points out that firstly, they cause various health problems, including cancer and that secondly, they attack the immune system. Thus, the writer shows that they not only create challenges for the immune system but they also make it unable to do its job.
From the Paper
"Pesticides have served mankind since ancient times, mostly as insect repellents. More than fifteen hundred years before Christ, the Egyptians used natural preparations to get rid of fleas in their households. In the 1930s, a whole range of new products was developed to destroy or repel insects, rodents, fungi, weeds and other unwanted organisms. The most notorious of these new pesticides was DDT."

Abstract
This paper presents a review of legal issues surrounding a chemical castration law for the state of California. It looks at the design of the law as a measure to protect children from sexual offenders. The paper looks at current methods of chemical castration, the vagueness of the law and the question of whether chemical castration is a treatment or punishment.
From the Paper
"Today as it tries to deal with the reality of the sexual abuse of children within its borders the state of California is faced with a quandary. On the one hand the sexual abuse of children is an appalling fact that devastates thousands ..."

Abstract
The paper analyzes the relationship between anxiety and chemical dependency, including diagnosis, treatment, and comorbidity.
From the Paper
"Patients presenting with some type of chemical dependency; alcoholism, drug use/abuse and so forth, are often given what is known as a dual diagnosis. A differential diagnosis consists of ruling out various alternative diagnoses, ruling out an etiological, general, medical condition determining the specific primary disorder, and ultimately establishing boundaries between disorders or no disorders. A dual diagnosis in contrast refers to a case in which an individual presents with an emotional psychiatric problem along with an alcohol..."

Abstract
This paper shows that one of the main concerns in Chemical Mechanical Planarization processing is the material removal rate (MRR). The paper also critically reviews the existing MRR models of CMP and compares the assumptions, application aspects and limitations of the two groups? models.
From the Paper
"Chemical Mechanical Planarization (CMP) is the process of surface smoothing and planing by a combination of mechanical action and chemical dissolution. This process is achieved by rubbing a work piece against a polishing pad under load in the presence of chemically active slurry containing an abrasive. CMP is one of the most effective planarization technologies for achieving smaller feature size for the integrated circuit (IC) industry. "
