The studied mylonite granites are exposed as small bodies at the west of Qushchi in the West Azarbaijan Province. These rocks contain orthoclase, microcline, plagioclase, fish muscovite, tourmaline ± garnet as porphyroclast. The matrix is composed of recrystallized quartz, fine grained muscovite and low abundant epidote. According to petrographic and mineral chemistry studies and BSE images, to...
The cause of poor seed quality (germination) of soybean produced in the Early Soybean Production System in the midsouth USA is still not completely understood. Temperature, solar radiation, and soybean genotype may all be important factors involved. The objective of this research was to evaluate seed composition, mineral level, and nitrogen assimilation in high and low germinability soybean pla...
Abstract Background: Bone tissue is a type of dense connective tissue with rich networks of blood vessels and nerves. Bone is constantly being torn down and replaced in a remodeling process. Nutrition also plays an important role in bone health and strong bones need an appropriate diet. The aim of this study was to evaluate the effects of selective nutrients such as calcium, (Ca) vitamin D, ...
We have prepared the first examples of B9-connected trivalent aryl and alkyl phosphinoborane species via Pd-catalyzed phosphination of 9-iodo-meta-carborane. Our studies highlight the unique electronic features of the B9-connected meta-carboranyl moiety as compared to its C1-based analogue. This work suggests that the B9-functionalized meta-carboranyl substituent in these ligands exhibits more ...
mineral paragenesis of rodingitized basic rocks of iranian ophiolites are presented and metasomatic reactions between ca+2 bearing aqueous fluids issued during serpentinization of host ultramafic rock – with magmatic minerals of basic rocks leading to present paragenesis of rodingites are discussed. it is concluded that ca+2 rich aqueous fluid in equilibrium with serpentinite has high ca+2 chem...
Several strategies have been identified to address micronutrient malnutrition, including dietary diversification, nutrient supplementation, increased public health measures, and food fortification. Of these, food fortification is the most effective intervention to deliver vitaminand mineral-rich food to a large population. Fortification involves adding minute quantities of nutrients, such as vi...
The selective enrichment behavior of a labile substance, such as hydroxides, to the surface of particular mineral particles in river water was clarified by scanning electron microscopy/energy dispersive X-ray microanalysis (SEM-EDX). Individual particles other than diatom collected on a 0.45 microm filter from the Fuji and Sagami rivers, central Japan, were analyzed by SEM-EDX and classified in...
