To investigate the effect of gamma irradiation on the nutritional quality of maize and sorghum grains, packs were exposed to doses of 0 and 2 kGy in a 60 Co package irradiator. Irradiated and nonirradiated samples were stored at refrigeration temperatures. Proximate composition, minerals content, minerals bio-availability, tannins content, phytic acid content, protein fractions and in vitro pro...

Substituting fishmeal (FM) with vegetable meal (VM) can markedly affect the mineral composition of feeds, and may require additional mineral supplementation. Their bioavailability and optimal supplementation levels depend also on the form of delivery of minerals. The aim of the study was to determine the effect of different delivery forms of three major trace elements (Zn, Mn and Se) in a marin...

It is commonly believed that the composition of groundwater does not change naturally. So if a change is recognized through taste and/or odor, many may think that something bad has happened. Perhaps the aquifer has become contaminated, or something is wrong with the well. However, a common cause of changes in water quality is through natural variations within the aquifer. What gives groundwater...

The desirable physical and physiochemical properties of clay minerals have led them to play a substantial role in pharmaceutical formulations. Clay minerals like kaolin, smectite and palygorskite-sepiolite are among the world's most valuable industrial minerals and of considerable importance. The elemental features of clay minerals which caused them to be used in pharmaceutical formulations are...

expansive behavior is usually observed in soils, which contain fractions of clay minerals in their composition. water absorption of clay particles and change of natural water content of soil up to plastic limit and down to shrinkage limit will cause significant volume change in expansive soils and will result in severe damages to the structures, buildings and foundations. swelling potential is ...

Walnut (Juglans regia L.) were evaluated for some physical properties and chemical composition. Ripe fruits were determined for moisture (2.71 %), crude protein (14.6 %) crude fibre (1.8%) ash (1.57%), crude energy (576Cal) ether soluble extract (24.71%), nut (10.5g) and kernel (5.09g) veights. Relative density, refractive index...

-New and published experimental data on hydrothermally treated (2-kbar water pressure, 300-400~ natural clay minerals is used to construct phase diagrams in composition and pressure-temperature space which define the phase relations of mixed layering solid solution in dioctahedral (illitemontmorillonite) and trioctahedral expanding chlorite and corrensite-like minerals. Three major relations ar...

A field experiments were carried out at Shambat, Sudan (Latitude 15 40 ́N and Longitude 32 o o 32 ́E) in three consecutive seasons (2000/03) to investigate the effect of Bradyrhizobium inoculation and chicken manure or sulphur fertilization on minerals composition of soybean (Glycine max L.). The results obtained showed that inoculation, chicken manure, sulphur and their interactions significantl...
