中药制剂抗IBDV效果的观察

选用金蓝、黄花两种中药注射液 ,在非免疫鸡胚中进行抗IBDV效果试验 ,黄花和金蓝注射液在 5 0 0倍稀释浓度下 ,均具有抗IBDV作用 ,接种病毒后混合组试验中鸡胚平均存活 15 4h ,177h(P <0 .0 5 ) ,抑制组试验中平均存活 62h ,68.7h(P >0 .0 5 ) ,预防组实验中鸡胚被孵出 ,病毒对照组则平均存活只有 4 5h。     

乙酸纤维素薄膜电泳实验材料和缓冲液的改良替代研究

选用新鲜鸡蛋清作为蛋白电泳样品,通过对巴比妥巴比妥钠、硼酸盐和磷酸盐三种常用缓冲溶液的对比电泳实验研究,综合考虑电泳效果、试剂毒性和药品价格三方面因素,发现鸡蛋清和硼酸盐缓冲溶液完全可以替代传统教学中使用的人血清和巴比妥巴比妥钠缓冲溶液,作为高校蛋白质电泳基础实验教学中的新型实验材料和缓冲溶液.     

现代乌托邦精神——试论梁启超翻译与创作的政治小说

由于受工具论观念的影响，学界对梁启超翻译与创作的政治小说的研究存在很多不足之处。文章从乌托邦思想理论的视角考察政治小说的存在理由。作者认为，政治小说是晚清精英知识分子乌托邦精神的表征，体现了特定历史时期知识分子的价值立场和审美追求。

Improving content area reading comprehension of Spanish speaking English learners in Grades 4 and 5 using web-based text structure instruction

Reading and comprehending content area texts is important for academic and professional success as well as life skills necessary to maintain good health and quality lifestyle. Spanish speaking English language learners have shown poor performance on high-stakes assessments in reading comprehension. The number of Spanish speaking English learners (ELs) in our schools continues to increase at a fast pace, and therefore it is imperative that we address their reading comprehension needs swiftly and effectively. The text structure strategy has shown positive results on comprehension outcomes in many research studies with students at Grades 2, 4, 5, and 7. This study is the first implementation of instruction about the text structure strategy expressly designed to accommodate the linguistic and comprehension needs of Spanish speaking ELs in Grades 4 and 5. Strategy instruction on the web for English learners (SWELL) was designed to deliver instruction about the text structure strategy to Spanish speaker English learners. A randomized controlled study with pre and post-tests was conducted with 14 classrooms at fourth-grade and 17 classrooms at fifth-grade in high poverty schools where over 85% of students were Spanish speaking bilinguals or ELs. Analysis of data using multi-level models show moderate to large-effects favoring the students in the SWELL classrooms over the business as usual control classrooms on important measures such as a standardized reading comprehension test and main idea and cloze tasks. This research has practical implications for the use of web-based tools to provide high-quality and supportive instruction to improve Spanish speaking ELs reading comprehension skills.
