Interest in the effects of ultraviolet (UV) radiation on the marine environment surged after the Antarctic ozone hole was discovered in the mid 1980s. Much of the ensuing research has focused on quant...
UV-absorbing covers reduce the incidence of injurious insect pests and viruses in protected crops. In the present study, the effect of a UV-absorbing net (Bionet) on the spatio-temporal dynamics of th...
The first stars and quasars are known sources of hard ionizing radiation in the first billion years of the Universe. We examine the joint effects of X-rays and hard UV radiation from such first-light ...
Time series of daily UV radiation measured by the ground-based Brewer spectrophotometer #115 in Hong Kong during 1995-2005 were studied through statistics analysis, with focus on the variability and l...
Surface noontime spectral ultraviolet (UV) irradiances during May-September of 2000–2004 from the total ozone mapping spectrometer (TOMS) satellite retrievals are systematically compared with the grou...
Increasing atmospheric CO2 concentration affects calcification in most planktonic calcifiers. Both reduced or stimulated calcification under high CO2have been reported in the widespread coccolithophor...
Human activity influences a wide range of components that affect the surface UV radiation levels, among them ozone at high latitudes. We calculate the effect of human-induced changes in the surface er...
Ultraviolet (UV) radiation induced production of phytoalexin scoparone (6,7-dimethoxycoumarin) in the leaves and flavedo of various citrus cultivars. Using high performance liquid chromatography (HPLC...
A method of designing woven fabrics is presented from the point of view of protecting humans against UV radiation transmitted by fabric and the shape of inter-thread channels determined by the fabric ...
The purpose of the research presented was to analyse the influence of the fabric surface cover factor and fabric colour values on the degree of UV ray transmittance and the UV protective factor (UPF)....
Protostellar Disks under the Influence of Winds and UV Radiation
Stratospheric Ozone Depletion and Solar UV Radiation in the Arctic and Its Potential Impact on Human Health in Finland.
The intensity and spectral composition of visible light are known to influence fish predation on zooplankton. However, in clear-water systems, ultraviolet (UV) radiation (UVR) may also influence fish...
It is shown that Five Year Oscillation in Earth rotation is possibly caused by variable solar UV radiation and a corresponding perturbation mechanism is suggested.
New Method of Determination of the UV-Radiation Permeability through Cotton Cloth。
