Influence of environmental conditions on the earth pit resistance using earth pit simulator
Introduction: Electrocution is the cause of many deaths in the world annually, that electric current passing between the body and earth can be the reason; thus, it is of great importance to construct the ground protection system using earth pit. This study aimed to investigate the effective environmental conditions on the earthchr('39')s pit resistance using the simulation method. Materials an...
متن کاملThe Effect of Sun Radiation on the Course of Cutaneous Leishmaniasis in BALB/c Mice
Objective(s) Studies have described immunomedulatory effects of sun exposure and ultraviolet radiation on infectious and neoplastic diseases. Here the effect of exposure to low potency radiation of sun on the course of leishmaniasis in mice was studied. Materials and Methods Fifteen BALB/c mice were exposed to suberythemogenic doses of sun (mean 180 mJ/cm2/day of UVB) 2 months before and 4 m...
متن کاملMEMS based Sun Sensor on a Chip
A prototype sun sensor has been developed. It consists of a thin slice of silicon coated with a layer of chrome and a layer of gold with hundreds of small pinholes, placed on top of an Active Pixel Sensor (APS) image detector at a distance of 500 microns. Images of the sun are formed on the APS image detector when the sun illuminates the mask. Image processing of the Sun image is performed exte...
