Microbiology Leading strand DNA synthesis increases the frequency of UV-induced mutations in Escherichia coli SOUTHERN ILLINOIS UNIVERSITY AT CARBONDALE Douglas Fix BenurwarManasi JLEADING STRAND DNA SYNTHESIS INCREASES THE FREQUENCY OF UV-INDUCED MUTATIONS IN Escherichia coli Ultraviolet (UV) radiation ...
Ultraviolet (UV) light is a type of electromagnetic radiation on the electromagnetic spectrum. The frequency of UV light is higher than that ofvisible light. This means it has more energy, which makes its wavelength shorter. This increased energy causes chemical effects in many objects — such a...
Greater than 1.5 microW of tunable wavelength-modulated 308-nm radiation was generated by sum-frequency mixing of 90 mW of 835-nm diode-laser output and 1.5 W of 488-nm Ar(+)-laser output in a beta-barium metaborate crystal. Hydroxyl radicals formed in a discharge-flow reactor were detecte...
The cleaned substrates were treated with both ultraviolet (UV) light and ozone for 15 min before being spin-coated with different concentrations of the PEDOT:PSS solution at 5000 rpm for 30 s. The PEDOT:PSS-coated substrates were heated on a hot plate at 150 °C for 30 min ...

This chapter reviews the group frequencies in terms of the spectral regions in which they occur. The first part of the chapter outlines an orderly procedure for the initial interpretation of an unknown infrared radiation (IR) spectrum by regions. Then, spectra-structure correlations are shown in ...
coherent THz radiation; X-ray radiation; free-electron laser (FEL); frequency beating1. Introduction Terahertz (THz) radiation, with a frequency from 0.1 to tens of THz, has excellent applications in the fields of information and communication technology, high-resolution sensing, THz astronomy, ...
(2022), the transmittance of UV light (at 282 nm) through the biofilm structure of P. aeruginosa within a bioreactor decreased from 93.6% on day 1 to 33.6% on day 5 [15]. A conventional approach to controlling biofilms in water and wastewater treatment processes involves the application of...
Generation of UV radiation in a lithium tetraborate crystal by walk-off compensated Type I sum-frequency mixing Ultraviolet radiation is generated in two lithium tetraborate (LiBOor LB4) crystals by Type I walk-off compensated sum-frequency mixing (SFM) of the common... GC Bhar,P Kumbhakar,AK...
The effects of ultraviolet radiation on the gravitactic orientation of the freshwater flagellate, Euglena gracilis, were determined by a real time image analysis system. Both artificial UV radiation and solar radiation in a temperature-c... DP Hader,SM Liu - 《Current Microbiology》 被引量: 119...
