Simplified modeling of E. coli mortality after genome damage induced by UV-C light exposure

open access: yesScientific Reports, 2020
UV light is a group of high-energy waves from the electromagnetic spectrum. There are three types of UV radiations: UV-A, -B and -C. UV-C light are the highest in energy, but most are retained by the ozone layer. UV-A and -B reach the earth’s surface and

The impacts of ultraviolet radiation feedback on galaxies during the epoch of reionization

open access: yes, 2012
We explore the impacts of ultraviolet (UV) radiation feedback on galaxies during the epoch of reionisation by cosmological simulations in which hydrodynamics and the transfer of the H and He ionising photons are consistently coupled.

Charge Transfer Induced Molecular Hole Doping into Thin Film of Metal-Organic-Frameworks

open access: yes, 2015
Despite the highly porous nature with significantly large surface area, metal organic frameworks (MOFs) can be hardly used in electronic, and optoelectronic devices due to their extremely poor electrical conductivity.

A green chemical approach for nitration of aromatic compounds

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2009
Photochemical aromatic nitration of phenol and salicylic acid has been carried out in the presence of UV radiations and formation of products has been observed spectrophotometrically.

Black Hole as a Wormhole Factory

open access: yes, 2015
On general grounds, one may argue that a black hole stops radiation at the Planck mass, where the radiated energy is comparable to the black hole's mass.

Efficient optimization and mineralization of UV absorbers: A comparative investigation with Fenton and UV/H2O2

open access: yesOpen Chemistry, 2018
UV absorbers developed for finishing of textile materials play a significant role in protection against UV radiations but their discharge in wastewater during processing and laundry action also retain serious concern to living species due to their ...

Synergetic effects of U-V radiations and malnutrition of lens (experimental study)

open access: yesIndian Journal of Ophthalmology, 1991
The synergistic effects of protein deficiency and U-V radiation is cataractogenic as seen in our experimental model though individually these had no damaging effect on enzymatic profile and clinical appearance.

Temperature measurement by UV thermal radiation.

open access: yesQUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1994
Summary Accurate measurement of temperature is of considerable importance in materials processing, such as welding, thermal cutting, and heat treatment of metals. Radiation thermometry has a distinct advantage over other temperature detection methods, since it requires no physical contact with the work.

DURABILITY OF ANTICORROSIVE PROTECTION COATINGS FOR ELECTRO-ENERGETIC EQUIPMENT [PDF]

open access: yesJournal of Sustainable Energy, 2016
Determining the working life of the anticorrosive protection layers is of great importance for electro-energetic installations. In order to assess the durability of the paint layers have been achieved films of 100 ÷ 120µm from six different ...
