高校行政管理中信息整理的策略研究

加强高校行政管理中信息整理的研究是一条提高行政管理效益和效率的好途径。要通过对信息整理人员的培训、文档的管理、信息整理环境的建设及评价等措施实现高校行政管理的科学广泛、准确及时、真实适用、动态开放等要求,促进高校行政管理能力的不断提升。     

Structure and function of a calmodulin-dependent smooth muscle myosin light chain kinase

Summary In smooth muscle the M_r 20,000 light chain of myosin is phosphorylated by a calmodulin-dependent protein kinase. It consists of 2 subunits: calmodulin, an acidic protein of M_r 17,000 that binds 4 moles of Ca²⁺; and a larger protein of M_r circa 130,000. Activation of the kinase is dependent upon their association in the presence of Ca²⁺. Cyclic AMP-dependent protein kinase phosphorylation of the myosin light chain kinase occurs at 2 sites. It decreases the affinity of the kinase for calmodulin and a reduction in the rate of light chain phosphorylation occurs. The kinase has an overall asymmetric shape composed of a globular head and tail region for the skeletal muscle enzyme. Trypsin digestion of this kinase releases a fragment of M_r 36,000 from the globular region that contains the catalytic and calmodulin binding sites. Chymotrypsin digestion of the kinase from smooth muscle generates a fragment of M_r 80,000 that does not contain the calmodulin binding or cyclic AMP-dependent protein kinase phosphorylation sites. It is a Ca²⁺-independent form of the kinase that phosphorylates the light chain of myosin. These structural features indicate a regulatory role for the kinase in smooth muscle phosphorylation and contraction.

西北的色彩

西北传统建筑的色彩浓厚，饱和面粗犷，在宗教形式中则尤显夸张，极为华丽和庄重。璀的建筑设计中，空间处理落实到人为感知离不开色彩这一载体。利用手把握其机理实用大用。     

Shortening velocity of single muscle cells isolated from a molluscan smooth muscle

Summary The maximal unloaded shortening velocity (V_max) of smooth muscle cells isolated from the pedal retractor muscle ofMytilus was more than twice as large as that of the whole muscle, suggesting the presence of extracellular components which resist the contraction of the whole muscle. The V_max of the isolated cells was almost constant at cell lengths ranging between 0.5 and 0.831₀ (1₀, optimal length for tension generation) indicating that the intracellular resistance to contraction is negligible within this range of lengths.

钢管混凝土结构构件耐撞性能的试验研究

为研究钢管混凝土结构构件的耐撞性能,采用落锤式冲击试验方法对其抗侧向冲击性能及破坏特征进行研究.获得钢管混凝土试件在不同冲击能量下冲击力时程曲线和试件的最大侧向位移,并分析了试件破坏形态及特征.实验结果表明:管壁厚度一定时,冲击力时程曲线经历3个阶段:迅速加载、平台值和卸载;随着冲击能量的增加,试件的侧向挠度增大;当钢管混凝土受到侧向冲力时,构件有明显的屈服现象;冲击能量越大构件的动力响应越明显.表明钢管混凝土构件具有良好的抗冲击性能.
