The nickel-manganese (Ni-Mn) alloy coating prepared from DC electrodeposition process in sulphamate bath was studied. The effects of process parameters, such as current density and electrolyte composition, on the cathodic current efficiency, microstructure, internal stress and mechanical properties were investigated. Because of its crucial effect on the application to the electroforming of micr...

In this work, nickel-based electrodes were prepared using composite electrodeposition technique in a nickel sulphamate bath containing suspended microor nano-sized CeO2 particles. The prepared NieCeO2 composite electrodes exhibit an enhanced high catalytic activity toward hydrogen evolution reaction (HER) in alkaline solutions. X-ray diffraction patterns indicated that the CeO2 particles have b...

the present research designed to evaluate the effects of foliar application of methyl jasmonate (meja), salicylic acid (sa) and potassium sulfate on improving fruit quality and photosynthesis system. ten treatments include: sa (0.3, 0.6 and 0.9 mm), meja (0.5, 1 and 2 mm), potassium sulfate (0.5, 1 and 1.5%) and distilled water (control) were sprayed on pomegranate trees 2 and 7 weeks after ful...

background in contemporary practice, acute mesenteric ischemia (ami) remains a serious cause of morbidity and mortality in abdominal emergencies. objectives we report the measurement of peritoneal fluid potassium and ph on a small series of rats that developed extensive ami following the surgical ligation of superior mesenteric vessels and compare the results with control groups. materials and ...

for investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the research field of islamic azad university, jiroft, iran in 2013-2014. the main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of crop ...

vineyard management, plant nutrition, irrigation, genotype and pests and diseases are effective factors quantity and quality of crops. among mentioned factors, plant nutrition has more importance and nutrient imbalance in soil can affect crop quantity and quality. grape cluster necrosis at veraison time is important disorders in vineyard, because of lack of balance between potassium and magnesi...

the effects of different levels of nitrogen (100, 200, 300 and 400 mg/l) and potassium (125, 250 and 375 mg/l) on yield and leaf n and k concentrations of tomato were investigated in perlit culture using a factorial randomized design with three replications. the highest fruit yield was obtained with 200 mg/l n. higher levels of nitrogen decreased tomato yield. with increasing nitrogen concentra...
