BACKGROUND AND OBJECTIVE: Rotavirus vaccination is discouraged during hospitalization given concerns regarding live attenuated virus transmission, although recommended upon discharge. Infants should have vaccination initiated by 104 days of age or they become ageineligible. Our institution believed the known risk of severe disease in unvaccinated infants outweighed the theoretical risk of trans...

The adequacy of the UV Index (UVI), a simple measure of ambient solar ultraviolet (UV) radiation, has been questioned on the basis of recent scientific data on the importance of vitamin D for human health, the mutagenic capacity of radiation in the UVA wavelength, and limitations in the behavioral impact of the UVI as a public awareness tool. A working group convened by ICNIRP and WHO met to as...

South Africa has a high incidence of skin cancer and eye disorders because of the high number of sunshine hours per day. The ultraviolet (UV) index (UVI) provides a factual measure of the UV irradiance including biological effects. It is considered extremely important when gauging ultraviolet doses. A survey conducted across South Africa during January 1999 provided data records that contain ni...
The present study analyzed the risk of skin cancer due to ultraviolet erythemal irradiance (UVery) in Arica, Chile, using measurements of the solar ultraviolet index (UVI) between 2006 and 2011. The daily maximum value by biometer Yankee Environmental Systems (YES) solar ultraviolet B (UVB)-1 was measured between 2007 and 2012, and seasonal variations were clearly observed, with higher UVI leve...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
The provision of information to the public about current levels of the erythemally effective UV radiation is an important issue in health care. The quality of promoted values is therefore of special importance. The atmospheric parameter which affects the erythemally effective UV radiation under clear sky most is the total ozone content of the atmosphere. In this paper we examined the sensitivit...
BACKGROUND AND OBJECTIVE Rotavirus vaccination is discouraged during hospitalization given concerns regarding live attenuated virus transmission, although recommended upon discharge. Infants should have vaccination initiated by 104 days of age or they become age-ineligible. Our institution believed the known risk of severe disease in unvaccinated infants outweighed the theoretical risk of trans...
