Far Ultraviolet Diffuse Emission from the Large Magellanic Cloud [PDF]

, 2010
We present the first observations of diffuse radiation in the far ultraviolet (1000 -- 1150 \AA) from the Large Magellanic Cloud based on observations made with the {\it Far Ultraviolet Spectroscopic Explorer}. The fraction of the total radiation in the field emitted as diffuse radiation is typically 5 -- 20\% with a high of 45\% near N70 where there ...

Habitable Zones and UV Habitable Zones around Host Stars [PDF]

, 2010
Ultraviolet radiation is a double-edged sword to life. If it is too strong, the terrestrial biological systems will be damaged. And if it is too weak, the synthesis of many biochemical compounds can not go along. We try to obtain the continuous ultraviolet habitable zones, and compare the ultraviolet habitable zones with the habitable zones of host ...

Hawking Radiation and Ultraviolet Regulators [PDF]

Physical Review D, 1995
Polchinski has argued that the prediction of Hawking radiation must be independent of the details of unknown high-energy physics because the calculation may be performed using `nice slices', for which the adiabatic theorem may be used.

Solar Ultraviolet Radiation Exposure Among Opencast Miners in Namibia with the Use of Electronic Dosimeters: A Feasibility Study [PDF]

Annals of Global Health
Importance: The lack of information on exposure of opencast mineworkers to solar ultraviolet radiation, a group I carcinogen, was addressed. The feasibility of using electronic dosimeters in the determination of exposure to solar ultraviolet radiation ...

Skin protection from solar ultraviolet radiation using natural compounds: a review

Environmental Chemistry Letters, 2023
Skin exposure to solar ultraviolet radiation and pollutants causes several skin disorders, calling for protection methods such as sunscreen application. However, common sunscreen contains chemicals that have displayed toxicity when exposed to ultraviolet

Inflammatory Molecules Associated with Ultraviolet Radiation-Mediated Skin Aging

International Journal of Molecular Sciences, 2021
Skin is the largest and most complex organ in the human body comprised of multiple layers with different types of cells. Different kinds of environmental stressors, for example, ultraviolet radiation (UVR), temperature, air pollutants, smoking, and diet,
