The study of the ortho-to-para ratio of assorted gas-phase interstellar molecules such as H2, H2O, NH3, and H2O+ has gained interest in recent years, based partially on new spectral observations of light hydrides by the Herschel Space Observatory.Although these ratios can yield valuable information about the thermal history of the interstellar clou
The socio-economic and environmental effects of invasive alien plants have been well documented; however, little is known about expansion by expansive native species.In this study, the effects of expansion by the expansive native shrub species Euryops floribundus on soil and vegetation were examined in Machubeni communal land in the Eastern Cape Pr
Food safety issues caused by foodborne pathogens and spoilage microorganisms have become one of the public health challenges worldwide.Bacteriocins are antimicrobial peptides synthesized by some bacterial ribosomes and are widely used as bio-preservatives and food additives.However, bacteriocins may have some limitations when used individually, suc
Abstract In biological systems, the synthesis of nucleic acids, such as DNA and RNA, is catalyzed by enzymes in various aqueous solutions.However, substrate specificity is derived from the chemical properties of the residues, which implies that perturbations of the solution environment may cause changes in the fidelity of the reaction.Here, we inve
