The Beihuaiyang metamorphic zone was formed by the Early Mesozoic collision of the North and South China Blocks. It consisted of the Foziling and Luzhenguan complexes and was thought to have never afforded a deep subduction. A similar feature of the deformation in the Dabieshan UHP metamorphic rocks implies that these different tectonic units share the same geodynamic background. The early stage of deformation can be preserved on account of their relatively shallower subduction than that for UHP rocks. On the basis of an analysis of the geo- logical structure and geochronological results, five deformational stages have been recognized: a D1-Early compressional deformation which represents the continental subduction; a D2-Early exhumation deformation producing a syn-convergence exhumation; a D3-Main deformation, represented by an exhumation deformation with Late Triassic age; a D4-Doming and its margin extensional gravity collapse deformation and finally a D5-regional extensional deformation of Cretaceous that was mostly introduced by the migmatization and plutonism.

To date, various signal transducers, cytokines, growth factors, and hormones have been reported to play an important role in homeostasis of various organs. Various cells and organs are involved in the hepatic regeneration process, which proceeds as a result of the coordination of many factors. While these factors are well known to be involved in the liver regeneration after the liver injury, however, as the details of such mechanisms have not been sufficiently elucidated, the practical applicability of hepatic regeneration based on the action of these and cytokines growth factors is still unclear. In terms of the involvement of the autonomic nervous system in hepatic regeneration, cell proliferation resulting from direct signal transduction to the liver has also been reported and recent studies focusing on the inter-organ communication via neural network opened a novel aspect of this field for therapeutic applicability. Therefore, the appropriate understanding of the relationship between autonomic neural network and liver regeneration through various organs including brain, afferent nerve, efferent nerve, etc. is essential. This mini-review explains the principle of neural system involved in the inter-organ communication and its contribution on the liver regeneration upon the liver injury reviewing recent progress in this field.

CORRELATION INVESTIGATION BETWEEN CONTACT APPROACH SPEED OF HANDHELD METAL ROD AND DISCHARGE PARAMETERS FROM CHARGED HUMAN BODY

引用

Journal of Electronics(China) 2008年第3期25卷 384-388页

作者： Ruan Fangming Fujiwara Osamu Gao Yougang Institute of Electromagnetic Compatibility Beijing University of Post ＆ Telecommunications Beijing 100876 China School of Physics ＆ Chemistry Guizhou NormaI University Guiyang 550001 China Graduate School of Engineering Nagoya Institute of Technology Gokiso-cho Showa-ku Nagoya 466-8555 Japan

Characteristic measurement of contact discharge currents are made through a hand-held metal rod from charged human body. Correlation coefficients are obtained, through Statistic Package for Social Science (SPSS), for various charge voltages, which is based on the effect test of electrode contact approach speeds on discharge current parameters of current peaks, maximum rising slope and spark lengths. Discharge parameters at charge voltage 300V are independent on approach speed. For charge voltages equal to and higher than 500V, the contact approach speed has strong positive cor- relation with discharge parameters of the peak current and the maximum rising slope, whereas has strong negative correlation with the spark length.

Because the physical and chemical properties of nanosized materials mostly differ from the existing microsized materials, their potential impacts on human health and the envi-ronment will be topics under the serious discussions in press and in a number of international scientific journals. We analyze and summarize the existing data of the experimental study on the biological activities and adverse effects of nanoscale materials/particles including single wall carbon nanotubes, multi wall carbon nanotubes, titanium oxide and iron powders. Though some biological behaviors of nanoscale materials observed cannot be understood on the basis of the current knowledge, as the existing data are mostly preliminary, it is too early to make some ex-clusive conclusions on biological activities (or the toxicity) of any of nanoscale materials. The experimental techniques, the current topics, and the future research directions for this new re-search field are also discussed.

Crystalline MgMoO4 with monoclinic structure was synthesized by solid phase reaction at different temperature. The physicochemical and electrochemical properties of them were extensively investigated, it is found that MgMoO4 shows excellent cycling performance, especially for MgMoO4 synthesized at 600℃, the average irreversible capacity loss of the formal SO cycles is only 0.1198%. MgMoO4 synthesized at lower temperature, 500℃and 600℃exhibits higher capacity, nearly two times as that of MgMoO4 synthesized at high temperature, 700℃and 800℃.Moreover, ex-situ XRD experiments have been used to characterize the electrochemical lithiation and de-lithiation mechanism.

The surface of the spinel LiMn2O4 was modified with zinc oxide by a chemical process to improve its electrochemical performance at high temperatures. The physical properties of the prepared products have been investigated by X-ray diffraction (XRD), Scanning electron microscopy (SEM). The charge/discharge of the materials was carried at ImA/cm2 in the range of 3.0 and 4.4V at 55℃.The discharge capacity of ZnO-coated LiMn2O4 (117.11mAh/g) showed only 3% loss of the initial capacity (121.28mAh/g) over 60 cycles. The cycle ability improvement of the spinel LiMn2O4 coated with ZnO is very evidently at high temperatures.
