Midterm congressional elections provide an interesting testing ground for theories of voting and elections in America. Free from the contamination of national personalities and stylized issues that epitomize presidential campaigns, midterm elections provide a cleaner issue environment for investigating the effects of systematic short-term forces on congressional elections. The seemingly inevita...

a mathematical model was developed to predict the effects of wind speed, light, ph, temperature, dissolved carbon dioxide and chemical oxygen demand (cod) on dissolved oxygen (do) in fish ponds. the effects of organic feeds, aeration and fish activity were added to the model developed by kayombo et al. for waste stabilization ponds (ecological modeling 127(2000): 21-31) to reflect the situat...

This study reports the biomass accumulation, plant nutrient concentration, and uptake rates of plants in a constructed floating wetland (CFW) installed for sewage treatment application Australia. Plant accumulation was estimated based on field samplings throughout duration study. Analysis samples each species also completed to estimate mean tissue content. The concentration were then used total...

The used form conductivity susceptibility values ​​of measurement results GF instrument CMD-4 at coordinate points certain elevations. processed displayed 2D 3D contour maps with help seve...

Rock filters are an established technology for polishing waste stabilization pond effluents. However, they rapidly become anoxic and consequently do not remove ammonium-nitrogen. Horizontal-flow aerated rock filters (HFARF), developed to permit nitrification and hence ammonium-N removal, were compared with a novel vertical-flow aerated rock filter (VFARF). There were no differences in the remov...
