The present study has been conducted to assess the surface water quality of Halda River from September 2015 to March 2016. DO, BOD5, COD, pH, EC, Chloride, Alkalinity, and Hardness concentrations in water samples have been found to range within 0.93-5.15 mg/L, 30-545 mg/L, 43-983 mg/L, 6.3-7.3, 110-524 uS/cm, 12-56 mg/L, 35-67 mg/L, and 38-121 mg/L, respectively. Multivariate statistical analys...
Simian rotavirus SA-11 experimentally seeded, was recovered from raw domestic sewage by a two-step concentration procedure, using filtration through a positively charged microporous filter (Zeta Plus 60 S) followed by ultracentrifugation, effecting an 8,000-fold concentration. By this method, a mean recovery of 81% +/- 7.5 of the SA-11 virus, was achieved.
BACKGROUND During the summers of 1989-1992 we conducted four randomized intervention trials at four separate UK bathing locations judged of acceptable quality under current USEPA and EU criteria. The results showed bathers to be at increased risk of gastroenteritis, acute febrile respiratory illness (ICD-9 461-466, 480), ear and eye infections relative to non-bathers. The public health signific...
Rural and suburban development has been and will continue to depend heavily on the use of onsite private sewage systems. The exodus to rural settings combined with changing technologies for sewage disposal that reduce site limitations to development have raised a broad set of land use, infrastructure, and environmental concerns. In a study of development in Wisconsin, we found that the type of ...

Sphingobium sp. strain YL23, a novel bacterium isolated from sewage sludge of a domestic wastewater treatment plant, has been shown to completely degrade bisphenol A under aerobic conditions. Here, we describe a 3.8-Mb assembly of its genome sequence and major findings from its annotation.
Market volatility remains one of the most important research fields in agricultural economics.Interestingly, price transmission mechanism seems to be symmetric in sectors that are likely to be of high political power.This paper analyzes the price transmission effects from international markets to domestic markets for corn in Iran. For this purpose, we estimate the elasticity of substitution bet...
This paper is divided into three parts. The first summarizes the main conclusions of Sumner and Hallstrom's paper "Commodity Policy Compatibility with Free Trade Agreement" and makes some suggestions for further research. The second part presents some thoughts concerning Mexico's domestic agricultural policies in relation to the authors' analysis on the theme of the Workshop. The discussion fin...
Assemblages of aquatic and edaphic insects in three streams in Central Amazonia were used to evaluate the impact on one of the streams (Cururu) caused by an oil spill that occurred in August 1999. The Cururu stream had already been impacted by domestic sewage. These three streams were evaluated during four different periods of the regional hydrological cycle (falling-, low-, rising- and high-wa...
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 ...
