In 1993 and 1994 total, there were 247 people reported to have been bitten by animals in Benton County, Oregon. Of the 243 biting animals, 70 percent were dogs, 25 percent cats, and 5 percent other animals such as ferrets, mice, rats, bats, and skunks. Fifty-four percent of all bites...
This study had two purposes: to determine solid waste management needs of residents and organizations of the San Xavier District Indian reservation near Tucson, Arizona; and to develop a solid waste management plan to be recommended to the San Xavier District Tribal Council.
A solid waste generation study compared the...
The removal of microbial populations from potable water has been a practice with great importance towards public health, as it has resulted in the reduction of literally millions of cases of infectious disease. In the United States, pathogenic organisms are most commonly removed from drinking water through the application of...
Microorganisms can be a valuable tool in assessing the toxicity of heavy metals. The soil respiration rate is a commonly explored endpoint. I utilized a fully automated respirometer incorporating an infrared gas analyzer (IRGA) and developed a method for measuring the effect of Zn on soil microbial populations. Zinc, in...
This study was undertaken to design a Farm Labor camp that would satisfy all federal, state and local regulations which apply to the siting, construction, and maintenance of camps. The regulations applicable to Farm Labor Camps are also identified. A design of a Labor Camp with a central building for...
Chromium hydroxide sludge is the end product of the aluminum phosphate coating process used by a truck manufacturer in the Pacific Northwest. This sludge is listed as an (F019) hazardous waste by the Environmental Protection Agency, and must be landfilled in a hazardous waste landfill site. The purpose of this...
Ozone is recognized as one of the most dangerous irritants to eyes, throat, lungs and etc .. Chamber studies consistently have demonstrated adverse effects of ozone on human lung function. The results of epidemiological studies, however, have been controversial, partly because there are many factors that affect human lung function....
Calow (1983) realized that differences between parasites and their free-living
relatives can be explained by the differences in nutrient richness. I
propose a model that is based on Calow's idea which identifies the relative
position of different trophic strategies (e.g. predation, grazing, parasitism and
others) based on (1) the differences...
Elton (1927) realized that, intuitively at least, nature was complex and stable. And that the last property contributed to the first. This idea was challenged mathematically by Gardner and Ashby (1970) and May (1972), and in the years following various models have attempted to reconcile these opposing views. Unlike previous...
Antibacterial activities in the salivary glands of
female mosquitoes Aedes aegypti were investigated in this
study.
The mean salivary bacteriolytic activity, during a
period of 14-day of female mosquitoes exposed to five
different concentrations of Gram-positive bacteria
Micrococcus lysodeikticus in the sucrose meal, was
detected by a lysoplate method. A...
