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.
Morphology of Cold Bars in Early and Late Type Galaxies
We compare stellar orbits in an early (NGC 4314) and a late-type barred galaxy (NGC 1073). We find that these bars are cold in the sense that the majority of stars can be described as being nearby to periodic orbits. We place limits of (65km/s) and (50km/s) on the components of the diagonalized velocity dispersion ellipsoid matrix for stars in the bars of NGC 4314 and NGC 1073 respectively. Bot...
متن کاملA Catalogue and Analysis of X–ray luminosities of Early–type galaxies
We present a catalogue of X–ray luminosities for 401 early–type galaxies, of which 136 are based on newly analysed ROSAT PSPC pointed observations. The remaining luminosities are taken from the literature and converted to a common energy band, spectral model and distance scale. Using this sample we fit the LX :LB relation for early–type galaxies and find a best fit slope for the catalogue of ∼2...
متن کاملA Quantitative Morphological Comparison of Late-type Galaxies in Clusters and the Field at Intermediate Redshift
We present a comparison of late-type galaxies (Sa and later) in intermediate redshift clusters and the field using images from the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope (HST). Cluster and field galaxies are selected by matching photometric and spectroscopic catalogs of four cluster fields: CL0152-1357, CL1056-0337 (MS1054), CL1604+4304, and CL1604+4321. Concentrati...
