The number of breakthrough pathogenic activity in water distribution network system is constantly increasing day by day especially at level of consumption. Bacterial growth or survival rate often relates to acidity and alkalinity of water. Sudden changes in pH value and temperature indicates a possibility of present bacterial contaminant in aqueous environment. The observation of pH- and temper...

The present study aims at assessing the mechanical behavior of aluminum alloy (AA2024) subjected to exfoliation corrosion. material was exposed high temperature and subsequent low (HLA) treatment further heat-treated samples were corrosion for duration 48 96 h room temperature. HLA increases retention property in corrosive environment. Further, hardness impact strength also increased under envi...

hemicellulose of southern yellow pine wood spices was extracted by pressurized hot water at three different temperatures: 140°c, 155°c and 170°c. compounding with pp (polypropylene) was performed by extrusion after preparing wood flour and sieving to determine its mesh size. the ratio of wood to polymer was 50:50 based on oven-dry weight of wood flour. all extraction treatments and control samp...

PURPOSES The difference in predictors of bacteremia between elderly and non-elderly patients is unclear despite the aging of society. The objective was to determine predictors of bacteremia among elderly patients aged 80 years and older compared to non-elderly patients aged 18 to 79 years. METHODS A referral hospital-based retrospective descriptive study from April 2012 to March 2013 in Okina...

HAV is a very resistant virus in the environment because of by the absence of envelop. The virus is resistant against denaturation by drying, temperature as high as 56°C and as low as -20°C and acid at pH 3.0 [3,5,6]. The virus can also survive in used water for weeks at 20 °C temperature especially if the humidity is low. The virus is neutralized after heating at 70 °C for 4 min and inactivate...

an experiment was conducted to study the effect of sulfuric acid, temperature scales and the source of seed on to break hardness alfalfa seed (medicagoscutellatacvrobinson). this study was carried out as a factorial experiment based on randomized complete design with four replications at the agricultural collage of lorestan university in 2005. acid treatment as the first factor (to rinse with a...

Background: Many studies have been done in order to interpret correctly the results of ethanol analysis and its related problems. Unfortunately, it was not easy to determine BAC rate, due to postmortem different conditions or personal and clinical differences in metabolism and excretion of ethanol. The time between death and autopsy, the environmental conditions (temperature and humidity) are i...

Global warming is expected to raise the average temperature of tropical region by up 3–4°C in next 70 years. Due vulnerable living conditions that are predominant most developing countries region, this will dramatically affect indoor thermal performance exclusively, naturally ventilated buildings form majority residential less-industrialized nations. In addition, lack knowledge about built envi...

The kinetics of association and dissociation for the ouabain-Na+,K+-dependent ATPase complex have been studied in intact turkey erythrocytes as a function of external Na+ concentration, K+ concentration, and temperature. At free ligand concentrations substantially exceeding the concentration of available binding sites, the association reaction exhibits pseudo-first-order kinetics with an associ...
