Compared with published norms, African Americans endorse significantly more items intended to assess pathological anxiety about contamination on self-report instruments for obsessive-compulsive disorder. The current study suggests that this is not due to greater psychopathology in African Americans, but rather to differences in normal attitudes about cleanliness that also influence responses to...

Water resources are a prerequisite for the emergence and development of social space, its post-industrial advancement at current stage. Lack drinking water industry agricultural sector economy is characteristic many countries, which causes confrontation conflicts between regions countries on this issue. The analysis problem role regarding use philosophy policy some states stage relevant appropr...

the contents of as, cd, cu and mo were determined in soil surrounding meyduk tailings dam based on 21 surface soil samples. assessment of toxic element pollution in studied soil samples needs knowledge of pre-anthropogenic metal concentration to act as a reference against which measured values could be compared. estimating the background values was executed by sampling rocks adjacent to soil s...

The Seine river watershed is characterized by a high population density and intense agricultural activities. Data show low microbiological water quality in the main rivers (Seine, Marne, Oise) of the watershed. Today, there is an increasing pressure from different social groups to restore microbiological water quality in order to both increase the safety of drinking water production and to rest...

To assess the leakage of sanitation service in urban areas on the contamination of water streams and soil besides, a risk assessment study was conducted through the intake of edible plants from polluted irrigated suburban area of El-Zomor area, Egypt. The results revealed that concentrations of trace elements were several folds higher in the studied site compared to the background level in the ...

Immunoaffinity chromatography using conformation-specific antibodies yields pure factor IX from human plasma in a single rapid, facile purification step. We evaluated this technique to determine whether factor IX can be separated from human T cell leukemia virus-I (HTLV-I) and human immunodeficiency virus (HIV) in plasma supplemented with these viruses. Viral content was determined with an enzy...

One of the most important attributes of the polymerase chain reaction (PCR) is its exquisite sensitivity. However, the high sensitivity of PCR also renders it prone to falsepositive results because of, for example, exogenous contamination. Good laboratory practice and specific anti-contamination strategies are essential to minimize the chance of contamination. Some of these strategies, for exam...

Mining activities, ore concentrations, and transport processes generate large amounts of pollutants, including hazardous elements, which are released into the environment. This work presents results experimental research aimed at evaluating environmental risks soil plant contamination in two magnesite mining processing areas Slovak Republic, assesses phytoremediation potential dominant species....
