Imaging through hyperspectral technology is a powerful tool that can be used to spectrally identify and spatially map materials based on their specific absorption characteristics in electromagnetic spectrum. A robust method called Tetracorder has shown its effectiveness at material identification and mapping, using a set of algorithms within an expert system decision-making framework. In this s...

Toxic effects of two heavy metals, cadmium (Cd) and copper (Cu), and a fungicide, diethyldithiocarbamate, have been evaluated, alone and in association, on Spirodela polyrhiza duckweed cultivated in a synthetic mineral medium and in a distilled water medium. The composition of the culture medium influenced the toxicity of the three compounds and the effects of their associations were clearly sh...

As the number of persons living long lives following ostomy and bowel resection surgery increases, so do their questions about the effect of surgery on chronic conditions commonly associated with aging. The literature was reviewed to evaluate current evidence about the effect of bowel resection on the absorption of vitamins and minerals and related health concerns such as osteoporosis, gallston...

OBJECTIVE: We examined the effects of feeding nondigestible disaccharides, difructose anhydride III (DFAIII), maltitol, melibiose and cellobiose on calcium, magnesium and iron absorption in comparison to fructooligosaccharide (FOS) in normal and ovariectomized rats. METHODS: In experiment 1, six groups of male Sprague-Dawley rats were fed either a control diet (100 g cellulose/kg diet) or test ...

of alendronate and vitamin D3 on fractional calcium absorption in a double-blind, randomized, placebo-controlled trial in postmenopausal osteoporotic women. the role of vitamin D and calcium in osteoporosis management: an expert roundtable discussion. calcium absorption in severe vitamin D deficiency. The effect of vitamin D on calcium absorption in older women. A, et al. Vitamin D supplementat...

at the present time, flotation is the primary method for copper minerals separation from copper ores. the main copper ores that is extracted in the world is sulphide ore. the sulphide minerals are floated readily by using sulphydryl collectors. in the case of using xanthates , which are among the sulphydryl collectors, used more in the flotation of sulphide minerals of copper, the flotation of ...

Twenty-four crossbred barrows (average BW, 70.8 kg) were used to compare the digestibility of dry matter and the mineral absorption and retention by pigs fed two Cu sources. Dietary treatments were 1) basal (B) (16% CP corn-soybean meal-based diet, 36 mg/kg of Cu), 2) B + 200 mg/kg of Cu from CuSO4.5 H2O (CuSO4), and 3) B + 200 mg/kg of Cu from a copper lysine complex (CuLys). All diets contain...

Isotope technique including radioisotopes and stable isotopes is useful and potent tool for various scientific areas. Especially, enriched stable isotopes are indispensable tools for researchers in biological systems (Stürup et al. 2008). Stable isotope ratios are usually used in examining the biogeochemical cycling of light elements such as carbon(C), oxygen (O), nitrogen (N) and sulphur (S) i...

A previously described mathematical model of Zn absorption as a function of total daily dietary Zn and phytate was fitted to data from studies in which dietary Ca, Fe and protein were also measured. An analysis of regression residuals indicated statistically significant positive relationships between the residuals and Ca, Fe and protein, suggesting that the presence of any of these dietary comp...

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract The aim of this study is to determine the mass deposition flux of mineral dust to the tropical northeast Atlantic Ocean at the Cape Verde Atmospheric Observatory (CVAO) on the island Sao Vicente for January 2009.
