In order to investigate the effects of phosphorous and potassium fertilizers on some important morphological traits, agronomic characteristics and yield of red bean cultivars, an experiment was conducted at Agricultural Research Farm of Islamic Azad University, Arak, in the summer of 2013-2014 and in two consecutive years. This experiment was conducted as split plot based on randomized complete...

Unintentional As/P exchange has a significant influence on InAs/InP nanostructures growth. In this paper we report on the As/P exchange reactions at different temperatures studied by in situ stress measurements and reflectance difference characterization. When arsenic atoms incorporate at the InP surface an asymmetric stress is built-up that is responsible for quantum wires formation. We obtain...

The effects of Range Management Plans (RMP) on soil and vegetationcharacteristics were studied in Eshtehard rangelands at Alborz province. The parameters ofyield, canopy cover, range condition and trend, bulk density, Organic Matter (OM%),Nitrogen (N), Phosphorous (P) and Potassium (K) were estimated on soil samples in sitesof Ghenzel Cheshmeh as RMP and sanctum of Rahmanyeh village. The data w...

The purpose of this study was to identify food sources for major minerals such as calcium (Ca), phosphorus (P), sodium (Na) and potassium (K), and to evaluate the relationship between dietary intake of these minerals and serum lipids in healthy Korean adults. A total of 132 healthy men and women completed a physical examination and dietary record and provided blood samples for lipid profile ana...

total concentrations of mineral elements in soil bear little relation to their availability for plants. the dgt (diffusive gradients in thin-films) technique has been found to be a good predictor of trace metals, micronutrients, phosphorous and potassium bio-availability and uptake. in the dgt technique, elements are accumulated on a binding gel after their diffusive transport through a hydroge...
