Far UV-C, informally defined as electromagnetic radiation with wavelengths between 200 and 230 nm, has characteristics that are well-suited to control of airborne pathogens. Specifically, UV-C been shown be highly effective for inactivation pathogens; yet this same minimal potential cause damage human skin eye tissues. Critically, unlike UV-B, does not substantially penetrate the dead cell laye...

BACKGROUND Cutaneous leishmaniasis caused by L. major is an important public health problem in endemic areas. The aim of this study was to explore the therapeutic effect of microwave and or infrared radiation in the treatment of lesion induced in BALB/c mice by L. major inoculation. METHODS The footpad lesion was induced in BALB/c mice by inoculation of L. major promastigotes subcutaneously. ...

introduction: ionizing radiations are the hazardous agents in the workplace and all forms of ionizing radiation produce some type of injuries. awareness of application of protection guidelines and knowledge of the principles of radiation protection can play an important role in health of employees. survey of radiation employee’s levels of awareness and practical behavior is essential and should...

precipitation and air temperature data, only, are often recorded at meteorological stations, with radiation beingmeasured at very few weather stations, especially in developing countries. therefore there arises a need for suitablemodels to estimate solar radiation for a completion of data sets. this paper is about an evaluation of eight models foran estimation of daily solar radiation (q) from ...

Samples of soil collected from the Kennedy Space Center near the spacecraft assembly facilities were found to contain microorganisms very resistant to conventional sterilzation techniques. The inactivation kinetics of the naturally occurring spores in soil were investigated by using dry heat and ionizing radiation, first separately and then simultaneously. Dry-heat inactivation kinetics of spor...

PURPOSE Radiation-induced lung toxicity limits the delivery of high-dose radiation to thoracic tumors. Here, we investigated the potential of inhibiting the tumor necrosis factor-alpha (TNF-alpha) pathway as a novel radioprotection strategy. EXPERIMENTAL DESIGN Mouse lungs were irradiated with various doses and assessed at varying times for TNF-alpha production. Lung toxicity was measured by ...
