Hill, Ruth F. (Columbia University, New York, N.Y.). Relationship between ultraviolet sensitivity and ability to propagate ultraviolet-irradiated bacteriophage. J. Bacteriol. 88:1283-1287. 1964.-Mutants with a reduced ability to propagate ultraviolet-damaged bacteriophage T(1) were isolated from Escherichia coli strain B/r. The change in this ability varied from a slight to a very marked loss; ...

OBJECTION The aim of this study is to determine the effect of clothing and the environment on human exposure to ultraviolet light. METHODS The ultraviolet (ultraviolet A and ultraviolet B) light intensity was measured, and air quality parameters were recorded in 2014 in Beijing, China. Three types of clothing (white polyester cloth, pure cotton white T-shirt, and pure cotton black T-shirt) we...

Antioxidant capabilities of scoparone, the component of Artemisia scoparia and other medicinal plants, against lipid peroxidation induced by ultraviolet radiation or Fenton reaction have been analyzed. Lipid peroxidation was monitored by measuring the absorption spectra of the conjugated dienes and quantified by the Klein oxidation index. Obtained results imply that scoparone is a very efficien...

Indonesia is a tropical climate country which has the potential for high intensity of sunlight exposure. Several types exposure that receives are ultraviolet rays. According to National Agency Meteorology, Climatology and Geophysics, it provides information regarding impact on human activities in an index risk scale. The aim this research was creating recommender system based category providing...

A combination of high performance size exclusion chromatography with organic carbon detector and ultraviolet detector coupled with peak-fitting technique and fluorescence excitation-emission matrix spectrometry applied fluorescence regional integration method was conducted to determine the characteristics of organic matter during nitrification. The batch scale of bionet nitrification without or...
