The aim of the paper is FEM analysis of single coil BLDC motor operated as drive of small piston pump. The paper contains analysis of design, distribution of magnetic field, forces and torque under static and dynamic conditions. Voltages, currents, signals waveforms are also given as the results of analysis. The cogging torque and total torque are discussed in the paper.

Dust storms are a common phenomenon in arid and semi-arid areas, and their impacts on both physical and human environments are of great interest. Number of studies have associated atmospheric PM pollution in urban environments with origin in natural soil/dust, but less evaluated the dust spatial patterns over a city. We aimed to analyze the spatial-temporal behavior of PM concentrations over th...

objective: lack of exercise is the fourth cause of death in the world. there is an inverse relationship between physical activity and the risk of diabetes. the aim of this study was to determine physical activity status and its related factors among type 2 diabetic patients in hamadan, west of iran. materials and methods: this analytical-observational study was performed on320 type 2 diabetic p...

background : in recent years, due to its distinct geographical circumstances and position in a gorge, and accumulation of pollutants in surface air, isfahan, iran has become one of the most polluted cities in the iran in terms of air pollution. the purpose of this study was to estimate cardiovascular and respiratory diseases attributed to particulate matter of less than 10 microns (pm 10 ) in i...

It is a decade since the rst paper was published containing results determined using the general X-ray spectral-tting program XSPEC. Since then XSPEC has become the most widely used program for this purpose, being the de facto standard for the ROSAT and the de jure standard for the ASCA and XTE satellites. Probably the most important features of XSPEC are the large number of theoretical models ...

We report optical and IR observations of the ASCA X-ray pulsar system AX J0051-733. The relationship between the X-ray source and possible optical counterparts is discussed. Long term optical data from over 7 years are presented which reveal both a 1.4d modulation and an unusually rapid change in this possible binary period. Various models are discussed.
