We experimentally investigated the influence of developmental plasticity of ultraviolet (UV) visual sensitivity on predation efficiency of the larval smooth newt, Lissotriton vulgaris. We quantified expression of SWS1 opsin gene (UV-sensitive protein of photoreceptor cells) in the retinas of individuals who had developed in the presence (UV+) or absence (UV-) of UV light (developmental treatmen...

As an emerging light source, ultraviolet emitting diodes (UV-LEDs) are adopted to overcome the shortcomings of conventional mercury lamp, such as pollution. The degradation chloramphenicol (CAP) using three UV-LED-based advanced oxidation processes (AOPs)—UV-LED/persulfate (UV-LED/PS), UV-LED/peroxymonosulfate (UV-LED/PMS) and UV-LED/chlorine—was investigated. Results indicate that CAP can be m...

Most birds are able to sense ultraviolet (UV) visual signals. Ultraviolet wavelengths are used for plumage signaling and sexual selection among birds. The aim of our study was to determine if UV cues are also used for the process of food selection in wild turkeys (Meleagris gallopavo). We used avoidance conditioning to test the hypothesis that UV feeding cues can be used functionally for foragi...

Callus cultures were established in vitro from leaf explants of Malva neglecta and were sub-cultured several times until a rapid-growing cell line was obtained. The calluses were exposed to different doses of ultraviolet (UV) radiation as follows: 0, 432, 864, and 1296 J/m2 for UV B and 0, 612, 1284, and 1836 J/m2 for UV C, corresponding to 0, 30, 60, and 90 min radiations, in tandem. Exposure ...

Title of Dissertation: THE EFFECTS OF SOLAR ULTRAVIOLET-B ON THE PROTEOME AND ANTIOXIDANT DEFENSE SYSTEMS IN SOYBEAN LEAVES Chenping Xu, Doctor of Philosophy, 2007 Directed By: Associate Professor Joe H. Sullivan Department of Plant Science and Landscape Architecture Stratospheric ozone depletion has caused an increase in the amount of ultravioletB (UV-B) radiation reaching the earth's surface....

In order to evaluate the effects of ultraviolet radiation (UV; 280 400 nm) on aquatic ecosystems, and to predict the potential influence of enhanced ultraviolet-B radiation (UV-B; 280 320 nm) from ozone depletion, it is necessary to observe the effects of natural and experimentallyaltered UV on different biological and chemical systems, and to quantify measured responses as functions of irradia...

Mammalian retinae have rod photoreceptors for night vision and cone photoreceptors for daylight and colour vision. For colour discrimination, most mammals possess two cone populations with two visual pigments (opsins) that have absorption maxima at short wavelengths (blue or ultraviolet light) and long wavelengths (green or red light). Microchiropteran bats, which use echolocation to navigate a...

The influence of ultraviolet (UV)-induced oxygen vacancies on dynamic changes electrical conductance in a random-oriented SrTiO3 polycrystalline and single crystals with (100), (110), (111) surfaces is reported this study. It was discovered that large fraction ultraviolet-induced the are primarily contributed from grain boundaries, but these less influenced to reversible due UV irradiation. cha...

We present the results of a multiwavelength study of nearby galaxies aimed at understanding the relation between the ultraviolet and far-infrared emission in star-forming galaxies. The data set comprises new ultraviolet (from HST STIS), ground-based H , and radio continuum observations, together with archival infrared data (from IRAS and ISO). The local galaxies are used as benchmarks for compa...

Layered double hydroxides (LDHs) are an ultravioletlight (UV)-resistant material. In this study, two types of LDHs (Mg-Al-LDHs and Zn-Al-LDHs) were applied to modify bitumen by melt-blending. The effect of ultraviolet aging on the rheology and chemistry of LDH-modified bitumen was studied by means of dynamic shear rheometer (DSR), thin-layer chromatography with flame ionization detection (TLC-F...
