the survey of the virtual higher education in iran and the ways of its development and improvement
این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Cell wall, cytoskeleton, and cell expansion in higher plants.
To accommodate two seemingly contradictory biological roles in plant physiology, providing both the rigid structural support of plant cells and the adjustable elasticity needed for cell expansion, the composition of the plant cell wall has evolved to become an intricate network of cellulosic, hemicellulosic, and pectic polysaccharides and protein. Due to its complexity, many aspects of the cell...
متن کاملMicrotubules and Microfilaments in Cell Morphogenesis in Higher Plants
Microtubules and microfilaments play important roles in cell morphogenesis. The picture emerging from drug studies and molecular-genetic analyses of mutant higher plants defective in cell morphogenesis shows that the roles played by them remain the same in both tip-growing and diffuse-growing cells. Microtubules are important for establishing and maintaining growth polarity whereas actin microf...
متن کاملChina's Higher Education Expansion and its Labor Market Consequences
China’s Higher Education Expansion and its Labor Market Consequences Using a 1/5 random draw of the 1% census of 2005, we investigate how China’s higher education expansion commenced in 1999 affects the education opportunities of various population groups and how this policy affects the labor market. Treating the expansion as an experiment and using a LATE framework, we find that higher educati...
متن کاملDNA methylation and its role in the trophoblast cell lineage.
DNA methylation functions as cellular memory beyond generations of cells and is involved in many biological processes. Because of its relatively stable nature compared with the transcriptome, the DNA methylation profile of cells can also be used to evaluate developmental similarity and cellular phenotypes. Recent insights into 5-hydroxymethylcytosine have started to reshape our view of the epig...
