Our recent issue on “Equipment for eye care” (number 73, September 2010) addressed the importance of equipment in the delivery of eye care and covered maintenance, repair, training, purchasing, and donations. This issue (number 76) addresses similar concerns around surgical instruments and consumables. For an eye unit to function, instruments must be carefully managed so that they remain in goo...

coherent matter of indefinite shape or size; a considerable number or quantity. 2 It follows then, that the " local " EMS systems are not be able to manage all of the victims. For events that produce massive numbers of casualties, the system is overwhelmed and many victims whose lives possibly could have been salvaged in a multiple-casualty situation will succumb to their injuries/illnesses as ...

Background: Radon as a potential risk of radiation exposure is a natural radioactive element that can emit from rocks and soils. Due to solubility in water, it can be inhaled or consumed by the public. The purpose of this study was carrying out measurement and evaluation of radon concentration in samples of drinking water which are collected from water supplies of Borujerd. Materials and Method...

The main feature of the Fast-Field Cycling (FFC) Nuclear Magnetic Resonance (NMR) power supplies is to drive a controlled current fulfilling the requirements of this technique. This feature allows fast switching the current of the FFC magnet and performing accurate and repetitive current cycles. When designing this equipment the power losses is not a fundamental parameter of the optimization pr...

Recently, power quality (PQ) has because a significant issue for both power supplies and customers. Researchers in all developed countries know that power quality is one of the factors of losses in the network. Increasing power electronic equipment changes current waveform in distribution networks and this can cause many problems in networks. Distortion of voltage waveforms results in the appea...

Introduction: One of the main challenges of the health system is improving the quality of healthcare services by adjusting the costs. The right choice of tools will bring economic savings besides excellent service quality. Since medical supplies are among the fundamental and costly elements in providing services, the expertise of purchasing has become an important and complex issue. This study ...

The Canadian Organization of Medical Physicists (COMP) in close partnership with the Canadian Partnership for Quality Radiotherapy (CPQR) has developed a series of Technical Quality Control (TQC) guidelines for radiation treatment equipment. These guidelines outline the performance objectives that equipment should meet in order to ensure an acceptable level of radiation treatment quality. The T...

We report a simple and efficient colorimetric method to screen large numbers of bacterial strains for UV- and X-radiation sensitivity. We used reference radiation-sensitive and control strains of Escherichia coli K-12 to compare our colorimetric method to a standard clonogenic plating method. Our colorimetric method was as accurate as the standard method and was superior in terms of savings in ...

introduction in radiography, dose and image quality are dependent on radiographic parameters. the problem is caused from incorrect use of radiography equipment and from the radiation exposure to patients much more than required. therefore, the aim of this study was to implement a quality-control program to detect changes in exposure parameters, which may affect diagnosis or patient radiation do...
