Present study was carried out to investigate the anthelmintic potential of petroleum-ether extract of Portulaca oleracea against Pheretima posthuma as a species of earthworm. Various concentrations (25‐100 mg/ml) of petroleum-ether extract were evaluated for anthelmintic activity by recording the time required for paralysis and death of worms. Albendazole was used as standard. Result indicates ...

Administration (EIA) provides analyses used to assess proposed energy and environmental policies and to make energy forecast for the Annual Energy Outlook (AEO). The tool used by EIA for these mid to long term forecasts is the National Energy Modeling System (NEMS), a large-scale model of energy supply, demand, prices, and technologies. One component of NEMS is the Petroleum Marketing Module (P...

this study is carried out to estimate the potential evapotranspiration (pet) and crop coefficient (kc) for wheat, bl 3235 variety. a lysimeter is installed to estimate pet at the experimental farm of agricultural research center of bhairahawa, which is located in western part of nepal. the blaney-criddle formula is used to estimate the kc for wheat. the estimated values of pet and kc for wheat ...

The purpose of this study was to systematically examine the psychometric properties of the 14-item Resilience Scale (RS-14; Wagnild, 2009a). Exploratory and confirmatory factor-analytic methods were employed, including an analysis of measurement invariance models by sex and race/ethnicity. Descriptive statistics, reliability, and validity data were also calculated. Analyses were based on 2 samp...

Petroleum is a complex mixture of lipophilic chemicals, some of which are likely to be substrates for the microsomal mixed function oxygenases. Petroleum retailers, by virtue of their occupational exposure potential, are a group likely to receive relatively heavy exposure to petroleum products in comparison with the general public. Urinary thioether output may provide a simple, non-invasive tec...
