Conclusions Bcl 2 gene may play an important role in regulating the apoptosis of the basal cells while if plays a secondary role in the secretory cells of the prostate.
Through the analysis of the slope of IS and LM curve in China,we think it is difficult to find out by comparision the magnitude between the effect of fiscal policy and monetary policy. Having studied the ISLMBP model in open economy,we come to the conclusion that fiscal policy play a primary role and monetary policy play a secondary role in China.
Conclusions: It is suggested that the elevated PIG2 in portal hypertension is mainly due to the overproduction of PGI2 in vascular epithelium cells induced by increased portal pressure, and portosystemic shunting and liver dysfunction play a secondary role.
This result shows that, under the present parameter range, the gas viscosity would have a secondary role on the atomization speed and important influence on the droplet size.
(1) The pH curve of the extraction of succinate dehydrogenase by butanol indicates that the binding of succinate dehydrogenase to the mitochondria has a pK value of 8 7. In extraction there is a critical butanol concentration of about 8% at 3℃. From the temperature curve of extraction it appears that the heats of activation which dissociate the binding of succinate dehydrogenase with the inner membrane will be quite low if the binding is through ionic bonds, and high if the binding is through hydrophobic bo...
Crack initiation and propagation are main processes for the realization of mechanical rock fragmentation, which was considered by earlier inves- tigators to be either caused by shear stress or controlled by tensile Stress. And both theoretical analyses and experimental examination remain to be further improved. The present paper discusses the nature of the stre- sses by analysing both the direction of crack propagation and the crack pattern recorded in situ SEM indentation penetration. Besides, a theore- ti...
The distrjbulion of organic matter in uraniferous sandstone in a certain region of China, its physical and optical properties, chemical composition and contents are discussed. It is emphasised that the organic matter is mainly composed of lignite with small amount of humate and is derived from both deposition and redeposition. The role of organic matter in uranium ore-formation is studied——it plays a considerable role, but a secondary role, the main ore-forming factors are stratigrap...
