Therefore, it becomes … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,202 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Salivary Electrolytes during Normal Menstrual Cycle with Special Reference to OvulationS. Alagendran, Govindaraju Archunan, Enrique Orozco Bonnila Armando, Rosalinda Guevara GuzmanThere is evidence to imply that estrogen influences salivary electrolytes activity in women. Problem statement: In this study we investigated changes in sodium, potassium and inorganic phosphorus, calcium and magnesium which related to find out the precise day of ovulation. These changes might help to explain the fluctuation of ovarian hormones such as preovulatory estrogen surge. Approach: Human whole saliva … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractNephrocalcinosis in Female Rats Fed Diets Containing Either Pectin or CelluloseAhmed Alhaidary, H.E. Mohamed, A.C. BeynenProblem statement: There is evidence that the type of fiber influences the development of nephrocalcinosis in rats, but the effect of pectin was unknown. Approach: The effects of dietary pectin and cellulose on kidney calcification were studied in female rats. The diets used contained either 0.4-0.6% phosphorus and either cellulose (10%, w/w) or pectin. The purified diets used were balanced … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 7,534 accessesView PDFCite

El-SaidSea grass, marine algae and fish samples were collected from the Egyptian coast of Mediterranean Sea during September 2000 and March 2001. The contents of fluoride and some interfering ions (calcium, magnesium, sulphate, phosphorus and some heavy metals) ions and their concentration factors were determined in the dried samples. Fluoride contents in macrophytes, algae, muscle of fish samples were ranged … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractChanges in Leaf Characteristics with Tree Age in Dryobalanops beccarii Dyer in a Restored Forest of Sarawak, MalaysiaEmilla Yastari LAPOK, ONG Kian Huat, John Keen CHUBO, Patricia KING Jie HungStudy on leaf properties of an endangered dipterocarp tree species, Dryobalanops beccarii, was conducted in a restored forest. The study focused on the morphology, nutrient concentration and gas exchange in well-developed leaves of D. beccarii at different ontogenetic phases. The hypothesis tested that leaf physiological and morphological changes are related to the nutrient concentration level of D. beccarii leaves in … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 25 Sep 2017 · 7,542 accessesView PDFCite

Research ArticleOpen accessIn the abstractIMPROVING PHOSPHORUS NUTRITION OF COTTONWalter B. Gordon, Larry Murphy, Pawel WiatrakCrop recovery of applied Phosphorus (P) fertilizer can be low, especially during season of low soil temperature, which decreases plant root growth and nutrient uptake. The H2PO4- or HPO4-2 anions readily react with soil cations such as Calcium (Ca), Magnesium (Mg), iron (Fe) and Aluminum (Al) to produce various phosphate compounds of very limited water solubility. Specialty Fertilizer Products (SFP), … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 10 May 2014 · 7,110 accessesView PDFCite
