An experiment was carried out to assess the phosphorus status of free grazing goats at Faisalabad, Pakistan. Samples were collected fortnightly during summer and winter seasons of 2010 from soil and plants. The highest (1183±0.54 mg. kg1) levels of feces phosphorus were recorded in lactating goats during winter and (9.87±0.99 mg" kg1) in urine of male during winter. Similarly maximum (71.0±0.88 mg "kgt) phosphorus concentration was observed in the plasma of lactating animals. Milk contained (31.0±0.36) rag. L^-1 in winter while during the months of summer the highest values recorded in forages, soils, canal and tube well waters were (755±1.98) mg. kg^-1, (785±4.98) mg· kg^-1, (0.97±8.78) mg·L^-1 and (4.12±0.55) mg. L^-1, respectively. It was revealed from the current results that fecal matter, forage, milk, tube well and canal water contained lower amounts of P, while P levels in blood plasma was found within the critical limits. Therefore, phosphorus supplementations were required in the area under experimentation to meet the requirements of the animals for their normal growth. 展开更多

Current exertion is made to depict and search out the flow features imparted to viscid fluid flow over a rotational disk. Impression of magnetic field with rotating fluid is generated by interacting it in radial direction.Nano structured particles with magnetized fluid are also incorporated in the upshot of chemical reaction and absorptive/generative heat induction. Von Kumaran procedure is executed to obtain flow narrating differential expressions.Flow pattern regarding thermal, momentum profiles are comprehended with the support of shooting method and RungeKutta methods. Furthermore, to get more realistic view of result description computational algorithm is modified by improving Runge-Kutta coefficients with Cash and Carp method. The aspects of flow controlling parameters like momentum slip parameter, magnetic strength parameter, Brownian motion parameter, thermophoresis parameter are adorned in sketches. Findings of these architects are accumulated in conclusion section. 展开更多
