Taschenbuch. Condición: Neu. Neuware -This comprehensive study explores two critical aspects of agricultural toxicology and phytochemical analysis. First, the genotoxic effects of paraquat, a widely used non-selective herbicide, were assessed on maize (Zea mays) through controlled exposure at concentrations of 0.2, 0.6, and 0.8 mg/L. Using gel electrophoresis and clustering analysis, a clear concentration-dependent increase in DNA fragmentation was observed, particularly at 0.6 and 0.8 mg/L, indicating significant oxidative stress and genetic damage compared to herbicide-free controls. These findings reveal the potential risks of paraquat application on crop genetic integrity. Second, the phytochemical profile of fermented Artemisia annua leaf extracts, prepared via fermentation with Saccharomyces cerevisiae, was characterized using High-Performance Liquid Chromatography (HPLC). The analysis identified a diverse range of bioactive compounds, including phenols (notably p-coumaric acid at 11.995 mg/L), flavonoids, organic acids, and glycosides such as saponins, all of which contribute to the extract's antioxidant and pharmacological properties.…

Neuware -Il programma di certificazione in ingegneria petrolifera (PEC) della Midwestern State University è progettato per preparare le persone a lavorare nelle industrie del petrolio e del gas. Il programma PEC si occupa principalmente di geologia fisica, proprietà dei fluidi e delle rocce, valutazione delle formazioni, esplorazione, sviluppo, perforazione e gestione delle risorse petrolifere e di gas. Il programma PEC aiuterà gli individui a comprendere l'ingegneria dei giacimenti, l'ingegneria della produzione, l'ingegneria della perforazione e il completamento dei pozzi petroliferi. Al termine, gli studenti saranno in grado di progettare e selezionare le attrezzature di perforazione e produzione, stimare le riserve e gestire le proprietà di petrolio e gas. Il numero di ore di credito richiesto per il programma PEC è di 20 ore di credito semestrali. Motivazione: 1. Il programma PEC è aperto agli studenti che hanno completato i prerequisiti per i corsi PEC. Alcuni corsi di ingegneria petrolifera trasferiti possono essere applicati al programma PEC dopo una valutazione da parte della Scuola di ingegneria. Ci sono tre tipi di studenti che possono essere presi in considerazione per l'ammissione al programma di certificazione, quelli che hanno già completato una laurea e si candidano come post-baccalaureati.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.…
