Al-KahtaniProblem statement: Al-Khadoud Spring is one of the largest spring in Al-Hassa governorate (Saudi Arabia). Due to the extended domestic activities and urbanization as well as the continuous industrial and agricultural growth of the region, spring water quality is potentially changing. Approach: This study was conducted to measure toxic heavy metal concentrations in water and fish samples along the spring … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 11,808 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Yellow Mealworm as a Novel Source of ProteinA. E. Ghaly, F. N. AlkoaikProblem statement: Yellow mealworms of different sizes (4.8-182.7 mg) were grown in a medium of wheat flour and brewer’s yeast (95:5 by weight) to evaluate their potential as a protein source. Approach: There was an initial adjustment period (3-9 days) observed during which the younger larvae (4.8-61.1 mg) grew slowly while the older ones (80.3-182.7 mg) lost weight. After this … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 20,880 accessesView PDFCite
