Rivers can be contaminated with different pollutants such as trout farms. Evaluation of the effect of trout farm on water quality is important to give new permission for trout farm construction. In current work, the effect of constructed trout farms near the Deinachal River on some physicochemical properties namely chemical oxygen demand (COD), biological oxygen demand (BOD5), dissolved oxygen ...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
OBJECTIVE To assess the sanitary quality of drinking water in rural farms through counts of microbiological indicators. METHODS A total of 180 drinking water samples from sources, reservoirs and water from site of consumption were collected in 30 rural farms located in the northeast region of the sate of São Paulo. The most probable number of total coliforms, Escherichia coli and mesophilic m...
Water scarcity is a major and structural problem in arid and semi-arid regions across the world that greatly concerns environmental policy-makers. The problem of adjusting the demand exceeding the sustainable supply has been mainly tackled with demand policies, particularly through investment in water saving technology and promotion of irrigation efficiency programs. However, there have been ve...
This study was undertaken to determine the concentrations of carbofuran residues in water, soil and plant samples from selected sites in the farmlands in Kenya and to demonstrate the impact of Furadan use on the local environment. Soil, water and plant samples obtained from agricultural farmlands where the technical formulation Furadan has been used extensively showed high environmental contami...
Background and Aim: Salmonellosis is one of the most common digestive diseases in the world. Salmonellosis is caused by varieties of salmonella serotypes and there are concerns about the contamination of poultry and its products by this microorganism. Given that the carcasses of poultry, as a major source of infection with this microorganism, determine the frequency and the rate of this type of...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
Finite volume ocean circulation and particle tracking models are used to simulate water-borne transmission of infectious hematopoietic necrosis virus (IHNV) among Atlantic salmon (Salmo salar) farms in the Discovery Islands region of British Columbia, Canada. Historical simulations for April and July 2010 are carried out to demonstrate the seasonal impact of river discharge, wind, ultra-violet ...
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
