Aim In clear, cold-water lakes, ultraviolet radiation (UV) and temperature are two important stressors that may prevent the establishment of aquatic invasive species by inhibiting the survival of sensitive early life history stages. In this study, we develop a UV–temperature response model to predict the establishment potential of a warmwater fish, largemouth bass (Micropterus salmoides), in a ...

The recent surge in the use of filtering facepiece respirators (FFRs) during SARS-CoV-2 pandemic triggered economic and environmental concerns with regards to their safe reuse and/or disposal. Their decontamination through ultraviolet (UV) irradiation has proven efficient bench tests. Nevertheless, no study yet investigated what extent method’s performance was impacted by contamination method. ...

Birds utilize ultraviolet (UV) wavelengths for plumage signaling and sexual selection. Ultraviolet cues may also be used for the process of avian food selection. The aim of our study was to investigate whether a UV cue and a postingestive repellent can be used to condition food avoidance in red-winged blackbirds (Agelaius phoeniceus). We found that birds conditioned with an UV-absorbent, postin...

Suspension cultures of Catharanthus roseus were used to evaluate ultraviolet-B (UV-B) treatment as an abiotic elicitor of secondary metabolites. A dispersed cell suspension culture from C. roseus leaves in late exponential phase and stationary phase were irradiated with UV-B for 5 min. The stationary phase cultures were more responsive to UV-B irradiation than late exponential phase cultures. C...

Radio-frequency excited, low-pressure plasmas in halogen-containing gases are widely used to etch submicronic features in a range of materials during integrated circuit manufacture. Costly process-drift problems are often caused by the ubiquitous deposition of polymer layers on the reactor walls. Simple and robust sensors of the reactor performance are needed to monitor and manage these effects...

Classification of major secondary metabolite groups is described. A short account is also given to ultraviolet (UV) climatology and UV response in plants. Investigations regarding secondary metabolite production in plants, in vitro cultivated plant cell and tissue cultures under UV radiation, particularly UV-B (280-315 nm) and UV-C (200-280 nm) are reviewed. The capacity of plants, callus and t...

Ultraviolet (UV) energy has been used to kill microorganisms such as bacteria and viruses in air since the early 1900s. If sufficiently high doses of UV are used, the technology can very effectively sterilize air. Low UV doses and lack of uniformity of the UV radiation can, however, significantly reduce the germicidal effects of UV. This White Paper describes a new Advanced UV System (AUVS) tec...

We have examined the functional architecture of the turtle Pseudemys scripta elegans retina with respect to colour processing, extending spectral stimulation into the ultraviolet, which has not been studied previously in the inner retina. We addressed two questions. (i) Is it possible to deduce the ultraviolet cone spectral sensitivity function through horizontal cell responses? (ii) Is there e...

Ultraviolet renormalons, contrary to their infrared counterparts, lead to a universal contribution to the large-order behaviour of perturbative expansions in QCD. In this letter, we determine nature of the leading ultraviolet renormalon singularity for the inclusive hadroproduction cross section in ee annihilation, for hadronic τ decays and the moments of deep-inelastic scattering structure fun...
