As one of the most important causes water quality deterioration, NPS (non-point source) pollution has become an urgent environmental and livelihood issue. To date, there have been only a few studies focusing on conforming to estimation, sources are mainly concentrated in nitrogen phosphorus nutrients. Unlike that consider intensity loads, risk for China’s Fuxian Lake Basin was evaluated this st...

Flue-gas desulfurization (FGD) gypsum, a byproduct of coal-fired electrical utility plants, has been shown to effectively reduce phosphorus (P) leaching in many agricultural systems. However, its applications horticultural production systems have insufficiently researched resulting limited industry adoption. To evaluate the efficacy FGD gypsum P media, pine bark substrates were amended with at ...

As an ecological subsystem, a small watershed is mainly located upstream from lakes, rivers, or other water bodies. The characteristics of non-point source (NPS) pollution in are random and complex. Rainfall the direct driving force NPS pollution, different land-use types main factors affecting output watersheds. At present, watersheds serious, problem eutrophication prominent. Nitrogen (N) pho...

Since the calcium-protein relationship for a purified protein is adequately described by the law of mass action (l), it follows that the inconsistencies between the total calcium and total protein for sera (2) probably represent the cumulative effect of a number of variables. The present report deals with some of these variables as follows: the effect of excessive amounts of CaClz on the calciu...

Arabidopsis thaliana root hairs grow longer and denser in response to low-phosphorus availability. We tested the hypothesis that wild-type Arabidopsis would acquire more phosphorus under phosphorus-limiting conditions than mutants that do not have the root hair response. The growth and phosphorus acquisition of wild-type Arabidopsis (WS) were compared to two root hair mutants (rhd6 and rhd2) un...

In the present study the mild steel (MS) specimens were coated with Nickel-Phosphorus (Ni-P) using acrylic bath. Heat treatment was carried out on specimens under different temperatures and time periods in an inert atmosphere. The various mechanical and tribological tests were performed on specimens. Using weight loss method, the corrosion nature of the samples under different environments was ...
