In this paper we employ artificial neural networks for predictive approximation of generalized functions having crucial applications in different areas of science including mechanical and chemical engineering, signal processing, information transfer, telecommunications, finance, etc. Results of numerical analysis are discussed. It is shown that the known Gibb’s phenomenon does not occur.

Copper Ameliorates Fluoride Toxicity in Fluoride and Molybdenum Fed Rabbits

引用

Biomedical and Environmental Sciences 2013年第4期26卷 311-313页

作者： Arjun L KHANDARE uday KUMAR Priyanka shankar Shanker RAO Food and Drug Toxicology Centre National Institute of NutritionIndian Council of Medical ResearchPOJama-I-OsmaniaHyderabad-500007Andhra PradeshIndia Department of Pathology National Institute of NutritionHyderabadIndia

Hydrofluorosis is a major public health problem in India, which is aggravated by presence or absence of some minerals in water or food. Fluoride by itself or in combination with other elements like molybdenum （Mo） in diet or water changes excretion/retention of bone minerals. Sorghum and pearl millet grown and consumed in fluorosis endemic areas contained significantly higher amounts of Mo than that grown in non-fluorotic areas in India.
