对"扩散"和"渗透"的讨论

自由扩散和协助扩散都是可自由运动的微粒通过热运动而发生的2种过膜扩散．生物体内的渗透是自由水通过生物膜的协助扩散。     

<生态旅游>一书评介

近年来生态旅游一词频频见于宣传媒体 ,它代表一种时尚 ,更是反映人类自我教育、自我完善的一种行动。旅游活动从来都是作为个人的行为 ,作为某种精神和物质的消费。然而 ,随着全球性生态危机的出现 ,人们的环境意识不断增强。从关心自身到关心环境 ,从追求当前利益到追求长远的可持续发展 ,一种新的生态观正在形成。这就是生态旅游出现的时代背景。生态旅游被认为是旅游可持续发展的最佳模式 ,成为当代世界旅游业的新时尚 ,代表了 2 1世纪旅游业发展的方向和潮流。我国幅员辽阔 ,地貌、气候类型复杂 ,生物多样性丰富 ,有着开展生态旅游活动…     

生态学的“教”与“做”的教学模式探讨

根据高等师范院校培养具有创新知识和创新能力的新型人才的办学宗旨．从本校生态学课程开设理论教学学时数少、实验教学刚起步的实情出发,结合生态学基础性强、研究范围广、应用范围宽的学科特点,阐述了在生态学教学中,为了营造良好的生态学学习情境、激发学生的学习兴趣,教师为“教”所进行的筛选课程内容、改进教学方法和构建新的实验体系与培养学生探究应用能力即“做”的教学模式探讨与体会。

"Harshlighting" small blemishes on microarrays

Background  

Microscopists are familiar with many blemishes that fluorescence images can have due to dust and debris, glass flaws, uneven distribution of fluids or surface coatings, etc. Microarray scans show similar artefacts, which affect the analysis, particularly when one tries to detect subtle changes. However, most blemishes are hard to find by the unaided eye, particularly in high-density oligonucleotide arrays (HDONAs).     

Special Issue on "Computational Cardiology"

正We are pleased to announce a special issue on‘‘Computational Cardiology’’of the journal Genomics,ProteomicsBioinformatics(GPB),aiming to provide a platform for high-quality papers focusing on the topic and we invite submissions for this special issue(to be published in the Spring of 2016).Dr.Benjamin Meder(University of Heidelberg and German Center for Cardiovascular Research–DZHK,Germany)and Dr.Andreas Keller(Saarland University,Germany)are Guest Editors of this issue.
