In this research, novel functionally graded Ni-P coating was deposited with electroless process. The content of phosphorus was controlled to change gradual through the thickness of the coating. During the plating, bath temperature and pH were changed at specified intervals to obtain functionally graded structure. To compare the properties of functionally graded coating with Ni-P single-layer co...
A 2×2×2 factorial arrangement with control group was conducted to study the effect of different levels of microbial phytase, metabolizable energy and available phosphorus on performance, carcass characteristics and phosphorus and calcium content of tibia in broiler chicks. In this experiment, 1260 Ross 308 male broiler chicks allocated to 9 treatments in a factorial arrangement, with 2 levels o...
Seventy Two sediments from four stations (Anzali, Tonekabon, Noshahr and Amirabad), located in Caspian Sea-Iranian coast were examined on the basis of P-fractionation in autumn and winter of 2013-2014. Several forms of the phosphorus in sediment were separated and extracted according to sequential extraction method. Then the extracted phosphorus in each fraction was determined by UV–Vis spectro...

The purpose of this experiment was to compare the effects of calcium, phosphorus, and fennel extract (FE) and vitamin D3 on performance and egg shell quality in post molted Ross broiler breeders from 96 to 102 weeks. Each pen consisted of 10 hens and 1 rooster. This experiment was done in a completely randomize design with seven treatments (different levels of calcium, phosphorus plus fennel ex...
background/objective: hyperphosphatemia is the consequence of end stage renal failure. inadequate control of serum phosphorus results in elevated ca × p product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification. in this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis pat...
Violet has many application in landscaping and herbal medicine . Salicylic acid hormone and phosphorus Nano-fertilizer compounds are considered as effective in regulating physiological processes and plant secondary metabolites. Therefore, a factorial experiment based on completely randomized design with 2 agent salicylic acid and fertilizer phosphorus Nano-fertilizer in 3 replications. Spraying...
Citric acid has been reported to increase utilization efficiency of dietary phytate-bound phosphorus and protein. Objective of this study was to determine the effects of citric acid on growth performance and nutrient retention of broiler chickens fed diets having two levels of non-phytate phosphorus and rice bran. Giving a completely randomize design in 2 × 2 × 2 factorial arrangement, 144 broi...
In order to study the effect of application of nitrogen, phosphorus and biologic fertilizers on yield and yield components of native bean, an experiment was conducted as factorial in randomized complete block design with three replications in Lahijan, northern Iran in 2013. Treatments consisted of chemical nitrogen fertilizer (0, 60 and 120 kg ha-1 urea), chemical phosphorus fertilizer (0, 40 a...
sediments from the southern caspian sea, located in iranian coast were examined on the basis of p-fractionation (five forms of phosphorus) by a sequential extraction scheme. ninety-six surface sediment samples (for each season with triplicate) were collected from eight sampling transects in 10 and 100 m depths during summer and winter in 2010-2011. the result indicated that the most abundant fo...
