Wastewater Treatment Facilities have been built to remove biological and chemical waste from water as it is used. These facilities maintain a healthy environment for organisms as well as people because it removes potentially harmful material and kills pathogens that would easily spread through cities. Phosphorus is a compound of interest because a high concentration of it at discharge will even...

The impending phosphorus crisis Phosphorus is a nutrient essential to all living organisms, and thus, it is essential in food production for humans. Although it is the eleventh most abundant element on earth, phosphorus never occurs in its pure form and is always bonded with other elements forming other compounds, such as phosphate rock. More importantly, much of the phosphorus in soil is not a...

in order to investigate the integration of phosphorus fertilizer different levels and phosphorus solubilizing bacteria p.fluorescens on quantitative and qualitative forage yield of two fall barley cultivars, an experiment carried out at research farm of college of agriculture of university of tehran during 2009-2010. the experiment design consisted of three randomized complete blocks in a facto...

Rising temperature causes a process of phosphorus release, which can be characterized well using phosphorus release rates (VP). The objective of the present study was to investigate the major factors affecting sediment phosphorus release rates through a wetland habitat simulation experiment. The results showed that the VP of different wetland sediments were different and changed with the order ...

Grid-oriented, physically based catchment models calculate fields of various hydrological variables relevant to phosphorus detachment and transport. These include (i) for surface transport: overland flow depth and flow in the coordinate directions, sediment load, and sediment concentration and (ii) for subsurface transport: soil moisture and hydraulic head at various depths in the soil. These v...

We have performed in situ synchrotron X-ray diffraction experiments to assess the influence of aluminium and phosphorus on the austenite stability in low-alloyed transformation-induced plasticity steels during the high-temperature bainitic holding and the subsequent martensitic transformation during cooling to temperatures between room temperature and 100 K. Although the addition of aluminium i...
