Medical education and autonomy in teaching hospitals
Introduction. Despite the implementation of hospital autonomy in many developed (France, Denmark) and developing countries(Ghana, Zimbabwe, Kenya and Indonesia) since the early 1980s , relatively little research has been directed towards evaluating the experiences of these hospitals .Efficiency, equity, accountability and quality of care can be considered as four main evaluative criteria in ass...
متن کاملCell autonomy of HIF effects in Drosophila: tracheal cells sense hypoxia and induce terminal branch sprouting.
Drosophila tracheal terminal branches are plastic and have the capacity to sprout out projections toward oxygen-starved areas, in a process analogous to mammalian angiogenesis. This response involves the upregulation of FGF/Branchless in hypoxic tissues, which binds its receptor Breathless on tracheal cells. Here, we show that extra sprouting depends on the Hypoxia-Inducible Factor (HIF)-alpha ...

متن کاملDetection and Blanking of Gsm Interference in Radio-astronomical Observations
Radio-astronomical observations are increasingly disturbed by man-made communication signals, satellite and broadcast services. In particular, the GSM band is a highly saturated domain, full with interferers which are much stronger than radio astronomical signals. In this paper we propose a strategy to reduce this interference using its non-stationary nature. We describe a multichannel interfer...
متن کاملSIMPLE PULSE BLANKING TECHNIQUE and IMPLEMENTATION in DIGITAL RADIOMETER
Radio Frequency Interference (RFI) can adversely impact microwave passive remote sensing measurements, and prohibits passive observations outside protected portions of the radio frequency spectrum. A microwave radiometer including a digital back-end with a simple real-time RFI mitigation technique for reducing pulsed RFI has been developed to address this issue; the process is termed “asynchron...
