We investigate the approximate solution of the Dirac equation for energy-dependent pseudoharmonic and Mie-type potentials under the pseudospin and spin symmetries using the supersymmetry quantum mechanics. We obtain the bound-state energy equation in an analytical manner and comment on the system behavior via various figures and tables.

The development of stationary patterns on a thin polymer surface subject to an electric field is studied by means of the hexagonal-planform weakly nonlinear stability analysis and numerical simulations. The time evolution of the interface between the air and the polymer film on the unbounded spatial domain is described by a thin film equation, incorporating the electric driving force and the surface *** nonlinear interfacial growth includes the amplitude equations and superposition of one-dimensional structures at regular orientations. The pattern selection is driven by the subcritical instability mechanism in which the relative thickness of the polymer film plays a critical role.

The equilibrium partition ratio, k, has been measured for Mn, Mo, Si, Ni and Cu in a ductile iron with composition(wt.%): 3.45 C, 0.25 Mn, 0.25 Mo, 2.45 Si, 0.5Ni and 0.5Cu with different nodule counts obtained from different section sizes of13, 25, 75 mm in the as cast, austenitized(at 870 °C for times 1, 4 and 6 hours) and austempered(at 375 °C for times 1 to 1,440 min) samples. results show that Mn and Mo segregate positively at cell boundaries, but Si, Ni and Cu concentrate in an inverse manner in the vicinity ofgraphite nodules and there is a depletion ofthese elements at cell boundaries. Segregation curves for Ni and Cu are more smooth than for Si. Carbide formation has been observed at cell boundaries. Based on the results, the partition ratios for all elements decrease with increasing the nodule count. More carbide with coarser morphology has been observed in the microstructure with a lower nodule count. Austenitization for a longer time can decrease partition ratio, but cannot eliminate it entirely. Increasing the austenitization temperature has the same effect. Austenitizing parameters have no significant effect on carbides volume fraction. The kinetics ofaustempering is faster in higher nodule counts and subsequently better mechanical properties including higher ductility, strength and toughness have been observed for all austempering conditions studied.

AIM： To investigate the effects of experimental partial hepatectomy and normothermic ischemia-reperfusion damage on the time course of the expression of four different growth factor receptors in liver regeneration. This is relevant due to the potential therapeutic use of growth factors in stimulating liver regeneration. MeTHODS： For partial hepatectomy （PH） 80% of the liver mass was resected in Sprague Dawley rats. Ischemia and reperfusion （I/r） were induced by occlusion of the portal vein and the hepatic artery for 15 min. The epidermal growth factor receptor, hepatic growth factor receptor, fibroblast growth factor receptor and tumour necrosis factor receptor-1 were analysed by immunohistochemistry up to 72 h after injury. Quantitative rT-PCr was performed at the time point of minimal receptor expression （24 h）. reSULTS： In immunohistochemistry, eGFr, HGFr, FGFr and TNFr1 showed biphasic kinetics after partial hepatectomy with a peak up to 12 h, a nadir after 24 h and another weak increase up to 72 h. During liver regeneration, after ischemia and reperfusion, the receptor expression was lower; the nadir at 24 h after reperfusion was the same. To evaluate whether this nadir was caused by a lack of mrNA transcription, or due to a posttranslational regulation, rT-PCr was performed at 24 h and compared to resting liver. In every probe there was specific mrNA for the receptors. eGFr, FGFr and TNFr1 mrNA expression was equal or lower than in resting liver, HGFr expression after I/r was stronger than in the control. CONCLUSION： At least partially due to a post-transcriptional process, there is a nadir in the expression of the analysed receptors 24 h after liver injury. Therefore, a therapeutic use of growth factors to stimulate liverregeneration 24 h after the damage might be not successful.

Cowpea protein isolate(CPI)was subjected to various dry and wet heat pretreatments followed by sequential digestion with pepsin and pancreatin;the undigested residues were isolated as the indigestible cowpea proteins(ICPs).All the ICPs exhibited in vitro bile acid-binding capacity but ICP from the slow cooling-induced gelation had the highest yield(68%)and was used for rat feeding experiments to determine effect on plasma total cholesterol(TC).Groups consisting of 3 male and 3 female Sprague-Dawley rats each were fed hypercholesterolemic diets that contained casein only or casein that was partially substituted with ICP of CPI for 6 *** showed diet that contained 5%(w/w)ICP was more effective in preventing TC increase(1.8 mmol/L)when compared to increases of 9.34 and 4.15 mmol/L for CPI and casein only diets,respectively.

This paper studies ten Chinese coals at different ranks by means of cross polarization and magic angle spinning, combined rotation and multiple-pulse spectroscopy, and dynamic nuclear polarization. NMr is first reported. It is found that, compared with those obtained previously coat somples from other parts of the world, some Chinese coals at lower ranks display unusual characteristics, which imply peculiar chemical structures in the coals.
