Hepatocellular carcinoma(HCC)has one of the fastestgrowing rates of cancer-related incidence and mortalityin the United States(U.S.)(1-3).From 2009 to 2013,theaverage annual percent change(AAPC)for liver cancerincidence became the highest among other reported cancersfor both males(+2.9%)and females(+3.8%)(1).In addition,cancer-related mortality rates for liver cancer are the highestamong solid malignancies from 2010 to 2014 for males(+2.6%)and females(+3.0%)(1).

关键词： The present pagination reports both Brownian diffusion and thermophoresis aspects subject to magneto hydrodynamic Williamson fluid model. Assuming the flow is unsteady and blood is treated as Williamson fluid over a wedge with radiation. The governing equations are transformed into ordinary differential equations by using similarity variables. The analytical solutions of the transformed governing equations are obtained by using the Rk 4th order method along with shooting technique solver. The effects of various physical parameters such as Hartmann number local Weissenberg number radiation parameter unsteadiness parameter Prandtl number Lewis number Brownian diffusion thermophoresis wedge angle parameter moving wedge parameter on velocity temperature concentration skin friction heat transfer rate and mass transfer rate have been discussed in detail. The velocity and temperature profile deprives for larger We and an opposite trend is observed for concentration. The radiation parameter is propositional to temperature and a counter behaviour is observed for Pr.

A sand-based culture system using rock phosphate (P) was developed to simulate the situation in alkalinesoils, with respect to the dominant P form, and five wheat cultivars (Excalibur, Brookton, krichauff, Westoniaand Sunco) were tested in this screening system to compare their P uptake and utilisation efficiencies. Resultsshowed that these cultivars differed significantly in their ability to acquire P from the sparingly available form(rock phosphate in this case). The accumulation of P by Brookton was three times that by krichauff. Pconcentrations in plant tissues did not differ significantly, indicating that all cultivars were similar in Putilisation efficiency. A further experiment showed that the greater ability of a cultivar to take up P fromsparingly available form was related to the ability of a cultivar to acidify the rhizosphere. Seed P content wasa confounding factor in this system, and the use of relatively uniform seed with similar P content, preferablylow, was conducive to a successful outcome of the screening process.
