The Spitzer Mid-infrared Agn Survey. Ii. the Demographics and Cosmic Evolution of the Agn Population
We present luminosity functions derived from a spectroscopic survey of active galactic nuclei (AGNs) selected from Spitzer Space Telescope imaging surveys. Selection in the mid-infrared is significantly less affected by dust obscuration. We can thus compare the luminosity functions of obscured and unobscured AGNs in a more reliable fashion than by using optical or X-ray data alone. We find that...
متن کاملThe Cosmic Evolution Survey (cosmos): Subaru Observations of the Hst Cosmos Field
We present deep optical imaging observations of 2 square degree area, covered by the Cosmic Evolution Survey (COSMOS), made by the prime-focus camera (Supreme-Cam) on the 8.2 m Subaru Telescope. Observations were done in six broadband [B (4459.78), g0 (4723.18),V (5483.88), r 0 (6213.08), i0 (7640.88), z0 (8855.08)] and one narrowband (NB816) filters. A total of 10 galaxies were detected to i0 ...

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.
Gender Differences in the Prevalence of Electrocardiogram Abnormalities in the Elderly: A Population Survey in India
Background: The health transition in India reflects the growing burden of cardiovascular diseases. It is well-known that there are significant and meaningful differences in the measured electrocardiogram (ECG) parameters between females and males. Specific to ECG diagnosis and ischemia, reports have indicated a higher number of false positive results in female patients than in male patients. Th...
