inappropriate waste management is considered as an important factor for attracting wild animals to the inhabited area. this leads to food conditioning in some wild species, which changes their feeding behavior and food habits. usually this trend reduces the fear of wild species and leads to conflict between wild species and human. we sampled five landfill sites of villages and small towns in wh...

sludge production is an avoidable problem arising from the treatment of wastewater. the sludge remained after municipal wastewater treatment contains considerable amounts of various contaminants and if is not properly handled and disposed, it may produce extensive health hazards. on the other hand, this sludge has benefits for plants and soils. thereupon, land application of sludge has received...

land use may be regarded as one of the most important factors affecting theenvironment with respect to human activities. so far, destroying the rangelands andchanging them into the waste lands and poor rangelands has been proposed as the mostsignificant variations of land use done by human beings. this paper has been conducted toevaluate the variations of vegetation percentage and land uses in ...

Both soil nematodes and microorganisms have been shown to be sensitive bioindicators of soil recovery in metal-contaminated habitats; however, the underlying processes are poorly understood. We investigated the relationship among soil microbial community composition, nematode community structure and soil aluminum (Al) content in different vegetated aluminum-rich ecosystems. Our results demonstr...

With current agricultural practices the amounts of fertilizer N applied are frequently more than the amounts removed by the crop. Excessive N application may result in short-term accumulation of nitrate nitrogen (NO3-N) in soil, which can easily be leached from the root zone and into the ground water. A management practice suggested for conserving accumulated NO3-N is the application of oily fo...

Nuclear weapons making and testing, operation of enterprises of the nuclear industry, of military and civilian nuclear fleet, as well as peaceful nuclear explosions – all that led in the USSR to release of radioactive products into the environment. In some parts of the FSU radioactive contamination exceeded permissible levels. The necessity of remediation of such territories became evident. The...

A solid waste management crisis exists in many parts of the US as a result of the inability to site new landfills to replace the consumed capacity of existing landfills. Municipal solid waste (MSW) landfills can, and usually do, have a significant adverse impact on the individuals who own property in, reside in, or otherwise use, areas near the landfill. This leads those who stand to be adverse...

The principle aim of this study was to isolate dye degrading actinomycetes from soil, mainly from agricultural farm lands and waste disposal areas, followed by characterization of the obtained isolates and to screen for dye degradation potential. Experiments included collection of soil samples; isolation of actinomycetes by serial dilution and spread plate technique on ISP2 medium, screening fo...

Face clustering is a task to partition facial images into disjoint clusters. In this paper, we investigate a specific problem of face clustering in videos. Unlike traditional face clustering problem with a given collection of images from multiple sources, our task deals with set of face tracks with information about frame ID. Thus, we can exploit two kinds of prior knowledge about the temporal ...

Bacillary dysentery has long been a considerable health problem in southwest China, however, the quantitative relationship between anthropogenic and physical environmental factors and the disease is not fully understand. It is also not clear where exactly the bacillary dysentery risk is potentially high. Based on the result of hotspot analysis, we generated training samples to build a spatial d...
