Electronic devices in space applications may be Radiation Tolerant or Commercial off-the Shelf (COTS). Due to cost and unavailability in many applications, the latter is usually used. In applications such as spatial ones, the COTS equipment lacks reliability against threats like heavy ion radiation therefore, some alternatives should be considered to make the equipment resistant against the pro...
Introduction: Most of people are exposed to ionizing radiation sources during their lifetime including background, cosmic or man-made beams like radiation used in nuclear medicine and radiology. Due to unavoidable use of ionizing radiation in diagnosis and treatment of diseases, designing and correct implementation of radiation protection principles in order to reducing its har...
Equipment logistics, maintenance, and repair are important aspects of construction equipment management. A well-managed equipment fleet helps reduce downtime, as well as total maintenance and repair costs. With quickly growing fleets of equipment, large contractors tend to divert the maintenance and repair of equipment from equipment managers to project managers. As a result, the equipment mana...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Introduction: The ionizing radiation is increasingly applied in various fields for industrial and medical purposes due to its benefits. The aim of this study was to measure the radiation levels in six radiology departments of two educational hospitals in Ahvaz, Iran. Materials and Methods: The radiation levels were measured at six locations of six radiology departments, including behind the pat...
The design of anaesthesia equipment for use in hospitals in the developing world must take into account the local conditions, particularly whether reliable supplies of compressed oxygen and electricity are available. Designs should ensure that maintenance is feasible locally. International standards should encourage the design of suitable equipment to ensure safe anaesthesia for patients worldw...
OBJECTIVES This report presents estimates on the availability of pediatric services, expertise, and supplies for treating pediatric emergencies in U.S. hospitals. METHODS The Emergency Pediatric Services and Equipment Supplement (EPSES) was a self-administered questionnaire added to the 2002-03 National Hospital Ambulatory Medical Care Survey (NHAMCS). NHAMCS samples non-Federal, short-stay a...
BACKGROUND Maternal mortality in Sub-Saharan Africa remains a challenge with estimates exceeding 1,000 maternal deaths per 100,000 live births in some countries. Successful prevention of maternal deaths hinges on adequate and quality emergency obstetric care. In addition to skilled personnel, there is need for a supportive environment in terms of essential drugs and supplies, equipment, and a r...
In the FAIR control system the SCU (Scalable Control Unit, an industry PC with a bus system for interfacing electronics) is the standard front-end controller for power supplies. The FESA-framework is used to implement front-end software in a standardized way, to give the user a unified look on the installed equipment. As we were dealing with different power converters and thus with different SC...
