The capability of different manganese complexes to act as PS II electron donors in D1/D2/cytochrome b559 complexes has been analyzed by measuring actinic light-induced absorption changes at 680 nm (650 nm) and 340 nm, reflecting the photoaccumulation of Pheophytin⁻ (Pheo⁻) and the reduction of NADP⁺, respectively. The data obtained revealed: a) the donor capacity of synthetic binuclear Mn (III)...
Abstract Background and Objectives Informing and counseling donors with positive Transfusion Transmitted Infection (TTI) is essential for preventing them from donating blood in future, and starting treatment for reducing complications. So, we evaluated the referral of reactive donors. Materials and Methods This cross sectional study was conducted in Sh...
A comprehensive biogeochemistry model, DNDC, was revised to simulate crop growth and soil processes more explicitly and improve its ability to estimate methane (CH4) emission from rice paddy fields under a wide range of climatic and agronomic conditions. The revised model simulates rice growth by tracking photosynthesis, respiration, C allocation, tillering, and release of organic C and O2 from...
A bacterial isolate, designated strain SZ, was obtained from noncontaminated creek sediment microcosms based on its ability to derive energy from acetate oxidation coupled to tetrachloroethene (PCE)-to-cis-1,2-dichloroethene (cis-DCE) dechlorination (i.e., chlororespiration). Hydrogen and pyruvate served as alternate electron donors for strain SZ, and the range of electron acceptors included (r...
Title of Document: Investigating the mechanism of the hydrogen peroxide photoproduction from chromophoric dissolved organic matter Yi Zhang, Doctor of Philosophy, 2014 Directed By: Professor Neil Blough Department of Chemistry The photochemical pathways for H2O2 production from chromophore dissolved organic matter (CDOM) were investigated extensively, employing in part a selective sodium borohy...
