INTRODUCTION AND OBJECTIVE The effect of climatic conditions on the biting density and relative abundance of Simulium damnosum complex at Adani, Nigeria, from August 2010-January 2011 was investigated. MATERIALS AND METHODS The classical method of collecting blackflies for a period of 11 hours using human attractants was employed in the study. Monthly climatic data, such as rainfall, relative...

this study has been conducted to evaluate the effectiveness of the local made charcoal tubes against adsorption of benzene, toluene and xylene vapors. results indicate that desorption capacity and the recovery percentage decrease as the benzene, toluene and xylene concentrations and also relative humidity increase. it is concluded that the water vapor is the major interfere in the adsorption of...

An increase in average air temperature and frequency of rain events is predicted for higher latitudes by the end of the 21st century, accompanied by a probable rise in air humidity. We currently lack knowledge on how forest trees acclimate to rising air humidity in temperate climates. We analysed the leaf gas exchange, sap flow and growth characteristics of hybrid aspen (Populus tremula × P. tr...

The Bowen ratio-energy balance (BREB) is a micrometeorological method often used to estimate latent heat flux because of its simplicity, robustness, and cost. Estimates of latent heat flux have compared favorably with other methods in several studies, but other studies have been less certain, especially when there was sensible heat advection. We compared the latent heat flux of irrigated alfalf...

BACKGROUND Knowledge of seasonal trends in hospital-associated infection incidence may improve surveillance and help guide the design and evaluation of infection prevention interventions. We estimated seasonal variation in the frequencies of inpatient bloodstream infections (BSIs) caused by common bacterial pathogens and examined associations of monthly BSI frequencies with ambient outdoor temp...

in order to assess the drought tolerance in 15 lentil genotypes, a field experiment was conducted during 2001-02 growing season in dryland agricultural research institute (dari) station of shirvan, in northern khorasan, iran, under rainfed and irrigated conditions. the experimental design was rcb with three replications. data for agronomic traits of plant height, number of empty and filled pods...

BACKGROUND Acute gastroenteritis is one of the most common diseases among children and adults, and continues to cause a major problem of public health in Burkina Faso. The temporal pattern of rotavirus, norovirus, sapovirus, astrovirus, adenovirus and Aichivirus A was studied by examining prevalence of gastroenteritis viruses in association with meteorological variables in Ouagadougou, Burkina ...
