“副油箱”运动营养制剂对提高小白鼠运动能力及心、肝、骨骼肌的部分组织化学的影响

本实验观察“副油箱”运动营养制剂对提高小白民运动能力的影响。发现服用“副油箱”制剂可延长小白鼠一次性游泳力竭的时间．用组织化学方法可见，服用本品的小白鼠肝糖原、肌糖原、骨骼肌琥珀酸脱氢酶（ＳＤＨａｓｅ）、钙激活的三磷腺苷酶（ＡＴＰａｓｅ）活性均高于对照组。     

The Uncertain Future for Digital Visual Collections in the University

Digital documents in the networked information environment fundamentally change the ways that visual materials can be used in education and scholarly discourse. These new uses raise questions about research library strategies with regard to digitized visual materials as a part of their collections, challenge assumptions underlying intellectual property rights for images and their scope, and offer ways in which visual literacy can become a more integral part of the common educational experience.

The Technical Quality of Performance Assessments: Standard Errors of Percents of Pupils Reaching Standards

How accurate is the reported percent of students’reaching standards at the school level? How are standard errors for these statistics computed? How do estimates vary with choice of generalizability model?
