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...

In recent years, the risk of health effects caused by the increased exposure to Ultraviolet-B (UVB) due to stratospheric ozone depletion has received wide attention. In the US, there are two ways to accurately measure the UVB. They include: 1) the National Aeronautical and Space Administration (NASA) Nimbus-7 total ozone mapping spectrometer (TOMS), and 2) the United State Department of Agricul...

A wavelet software package named Uvi Wave has been developed by the Signal Theory Group, in the University of Vigo, to provide a simple way to work with wavelets. So, the toolbox may be useful to make easier the understanding of theoretical concepts. Moreover, it provides an experimentation platform for wavelet applications. This paper describes the contents and main features of Uvi Wave, that ...

We examined condom attitudes, perceived vulnerability to HIV, HIV testing experiences, and sexual and substance use risk behaviors of 161 active Latino male gang members, aged 18-26 years old, living in Los Angeles, California. Gang members reported negative condom attitudes and a perceived vulnerability to HIV. The majority (53%) of gang members reported unprotected vaginal intercourse (UVI) i...

BACKGROUND The older population is a risk group for hypovitaminosis D. The Ultraviolet Index (UVI) can be an indicator of potential for cutaneous synthesis of vitamin D but physiological and other environmental factors also influence vitamin D synthesis and status. Knowledge about vitamin D status in Portuguese older adults is limited. This study aims to explore the association between Ultravio...

Ultraviolet radiation is a highly energetic component of the solar spectrum that needs to be monitored because harmful life on Earth, especially in areas where ozone layer has been depleted, like Chile. This work first address long-term (five-year) behaviour ultraviolet erythemal (UVER) Santiago, Chile (33.5° S, 70.7° W, 500 m) using situ measurements and empirical modelling. Observations indic...

Thinning of the atmospheric ozone layer leads to elevated levels of Ultraviolet-B (UVB) at the Earth's surface, resulting in an increase of health risks to living organisms due to DNA damage. This paper examines the multidecadal changes of total column ozone from 1979 to 2005 with the aid of ground-based UVB stations using the ultraviolet multifilter rotating shadow-band radiometer (UV-MFRSR). ...

Crystals of two new inorganic uranyl silicates, Cs[(UO6)2(UO2)9(Si2O7)F] (1) and Rb2[(PtO4)(UO2)5(Si2O7)] (2), were produced from melts in evacuated silica tubes. Their structures have been solved by direct methods: 1 is trigonal, P-31c, a = 10.2040(3), c 17.1278(5) Å, V 1544.45(10) Å3, R1 0.042; 2 tetragonal, P4/mbm, 16.0400(24), 3.9231(6) 1009.34(10) 0.045. the first example cation–cation int...

[1] Precipitating particle data from the DMSP F12 and F13 satellites has been merged with image data from the Ultraviolet Imager (UVI) on the Polar satellite. UVI images were combined within single transpolar passes of the DMSP F12 and F13 satellites. Pixel irradiances were then averaged into 1 1 bins along the satellite tracks, thus generating along-track irradiance profiles. Similarly, energy...

Recently Cabrol et al. (2014), hereafter C14, reported measurements of the UV Index (UVI) reaching 43.3 at a high altitude location in the Andes (Licancabur; 22.5◦ S, 67.5◦ W, 5917m a.s.l.). This value is much larger than those previously reported from other high altitude tropical locations. For example, UVI maxima reported for Mauna Loa (19.5◦ N, 155.6◦ W, 3397m a.s.l.) (Bodhaine et al., 1997;...
