降雨引发的浅层滑坡具有区域性的群发效应，能够在短时间内造成大量的灾难性损失。降雨过程的动态性及多样性直接影响着滑坡发生的位置及强度。本项目从降雨对浅层滑坡演化过程的作用机理入手，将滑坡的地质机理和变形失稳过程考虑到滑坡危险性评价的研究中，确定区域浅层滑坡灾害强度量化方法，在武陵山区滑坡灾害调查数据统计分析的基础上，建立土体结构的概化模型，分析不同土体结构模型的入渗特征，研究坡体不同部位的及其相邻坡体坡体之间的雨水运动规律；进行室内物理模型试验，构建降雨入渗条件下浅层滑坡的力学计算模型，提出浅层滑坡变形失稳

This project develops new technology toward Video2Sim:automatically converting a video into a virtual world,where scenes are reconstructed,actions are re-enacted,and alternative outcomes are simulated by a computer.Such a system does not yet exist due to

We plan to continue to develop and assess the efficacy of novel approaches for the treatment of malignant disease based on studies in dogs with spontaneously occurring malignancies. Studies in dogs with malignant lymphoma have shown that some dogs treated

The long range objectives of this project are to characterize fundamental properties of the replication-specific mammalian DNA polymerase alpha (pol alpha) and its structural gene and to discern within them unique sites and/or mechanisms which can be expl

Mammalian spermatogenesis is a hormone-dependent process regulated mainly by follicle-stimulating hormone (FSH) and testosterone (T). The effects of these hormones on germ cell (Gc) differentiation are believed to be indirect, mediated through the somati

Experimental autoimmune myasthenia gravis (EAMG) produced in C57B1/6 mice by immunization with Torpedo acetylcholine receptor has been modulated and attenuated by the in vivo administration of suppressor T cell lines and clones derived from lymph node cel

The objectives of this research are to define those immune mechanisms including allergy which have been suggested but not established as important in the pathogenesis of otitis media with effusion (OME). OME is a multifactorial syndrome in which infectio

The literatures on behavioral approaches to marital distress and behavioral marital therapy are summarized in terms of implications for understanding and preventing marital distress. Evidence is presented that communication and exchange deficits may be e

We have shown previously that the ecf gene of E. coli is intimately associated with the active transport of amino acids and certain simple saccharides. Because of its importance in cellular processes, biochemical and genetic characterization of this ener
