in order to investigation the effect of different fertilization treatments on nutrient and essential oil contents in dragonhead drug (dracocephalum moldavica l.), an experiment was conducted in the station of agricultural research in urmia on 2008. treatments (nitroxin, barvar phosphate biofertilizer, biosulfur, nitroxin+ barvar phosphate biofertilizer, barvar phosphate biofertilizer + biosulfu...

In this article, the effect of potassium on structure and anticorrosion properties of zinc phosphate pigments has been investigated. The co-precipitation method was selected as synthesis method of potassium zinc phosphate pigment. Then the synthesized pigment was characterized by x-ray diffraction XRD, Fourier transform infrared FTIR and Raman spectroscopy. Morphology of the powders was investi...

Potassium citrate is prescribed to decrease stone recurrence in patients with calcium nephrolithiasis. Citrate binds intestinal and urine calcium and increases urine pH. Citrate, metabolized to bicarbonate, should decrease calcium excretion by reducing bone resorption and increasing renal calcium reabsorption. However, citrate binding to intestinal calcium may increase absorption and renal excr...

Native sodium and potassium adenosine triphosphatase from guinea pig kidney accepted a phosphate group from radioactive inorganic phosphate to form an acyl phosphate bond at the active site in the presence or absence of sodium ion. Magnesium ion was always required. In the presence of sodium ion and absence of adenosine triphosphate, there was no phosphorylation by inorganic phosphate. Addition...

Native solium and potassium adenosine triphosphatase from guinea pig kidney accepted a phosphate group from radioactive inorganic phosphate to form an acyl phosphate bond at the active site in the presence or absence of sodium ion. Magnesium ion was always required. In the presence of sodium ion and absence of adenosine triphosphate, there was no phosphorylation by inorganic phosphate. Addition...

Potassium depletion in rats augments the specific renal lesions of phosphate loading. Since it has been shown that phosphate loading increases the specific cardiac lesions of potassium deficiency (12), it is concluded that the similar types of electrolyte imbalance (potassium depletion-phosphate load) act conversely in the two organs.

Thiobacillus thiooxidans cells became more hydrophobic but less adhesive to elemental sulfur in the presence of increasing potassium phosphate concentrations. At a fixed concentration of potassium phosphate, however, there was a peak of both cell hydrophobicity and adhesion to sulfur at around pH 5. Oxidation of sulfur by the cells was affected in a complex manner by the phosphate concentration...

the current study was conducted in order to evaluate the effect of mono and di-potassium phosphate combination (mdkp) on some quantitative and qualitative characteristics of iranian pomegranate (cv. malas-e-saveh) in pomegranate research center of saveh city, in 2012. to adjust the ph of the solution, the mono potassium phosphate and di-potassium phosphate combined with each other in the ratio ...

A green and convenient method for the synthesis of 2-amino-3-phenylsulphonyl-4H-chromenes by a one-pot three-component condensation of 1-naphthol, phenylsulphonylacetonitrile and aromatic aldehydes under solvent-free conditions using potassium phosphate tribasic trihydrate as an efficient catalyst is described. The reaction of 1-naphthol with phenylsulphonylacetonitrile and various aromatic...
