Bisphenol A (2,2-bis(4-hydroxyphenyl)propane), a chemical compound used in the manufacture of polycarbonate, epoxy and polysulfonate resins, can alter the endocrine system, causing adverse effects in the reproductive systems of humans and animals. More recently, the application of advanced oxidation processes (AOPs) has been recommended to treat toxic and/or biorefractory compounds including BP...

Attenuation of UV-B radiation in the water column occurs due to absorption and scatter but in shallow clear freshwater systems enhanced UV-B radiation might be of importance in affecting aquatic organisms. Two laboratory experiments were performed to determine whether two species of charophytes typical for shallow waterbodies, such as Chara polyacantha and Nitella hyalina, are negatively affect...

Mature green 'Maradol' papaya fruits were exposed to ultraviolet (UV)-C irradiation (1.48 kJ·m(-2)) and stored at 5 or 14 °C. Changes in total phenols, total flavonoids, enzymatic activities of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD), as well as the scavenging activity against 2,2-diphenyl-1picrylhydrazyl (DPPH) and 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals ...

UV-A (ca. 365 nm wavelength, a.k.a. ‘black light’) photocatalysis has been investigated to comprehensively mitigate odor and selected air pollutants in the livestock environment. This study was conducted confirm performance of on swine farm. The objectives this research were (1) scale-up treatment, (2) evaluate mitigation odorous gases from slurry pit, (3) test different UV sources, (4) effect ...

PURPOSE To demonstrate the antimicrobial properties of riboflavin/UV-A (365 nm) against fungal pathogens. METHODS The antimicrobial properties of riboflavin/UV-A (365 nm), with or without previous treatment with amphotericin B, were tested on three groups of fungi selected from severe cases of keratomycosis: Candida albicans, Fusarium sp, and Aspergillus fumigatus. They were tested by using K...

In this paper we address the following problem of nondestructing testing: to determine, within an elastic body , the possible presence of defects in the form of either cavities or rigid inclusions, from measurements of traction and displacement taken at the exterior boundary of . Let us denote by D the unknown, possibly disconnected, defect and let us assume that D is an open set compactly cont...

The effect of bactericidal UV-C treatments (254 nm) on Escherichia coli O157:H7 suspended in apple juice increased synergistically with temperature up to a threshold value. The optimum UV-C treatment temperature was 55 °C, yielding a 58.9% synergistic lethal effect. Under these treatment conditions, the UV-heat (UV-H55 °C) lethal variability achieving 5-log reductions had a logistic distributio...

Our previous studies indicated that SPATA12, a novel spermatogenesis-associated gene, might be an inhibitor involved in spermatogenesis and tumorigenesis. To obtain a better understanding of the functions of SPATA12, a yeast two-hybrid screening system was used to search for interacting proteins, and chromodomain helicase DNA binding protein 2 (CHD2) was successfully identified. Bimolecular flu...
