The chemical composition of samh seeds have been investigated. Proximate analysis showed a composition of 22.25% protein, 5.7% moisture, 5.6% fat, 4.0% ash, 9.7% crude fiber, and the remainder being total carbohydrates. Mineral element analysis revealed that potassium, magnesium, sodium and calcium were present as the major elements. Iron, manganese, zinc(More)
The seeds of Samh (Mesembryanthemum forsskalei) are 'Ostensibly Campylatropous' as they seem externally anatropous but internally they have a curved embryo and both the seed body and the funicle exchange shapes. The embryo occupies a cylindrical seed body and is surrounded by a thin layer of endosperm; the major part of the endosperm occupies an ovoid bulge(More)
Egypt has led the region (Africa and the Middle East, excluding Israel) in the availability of Internet services on a wide scale. Nevertheless, Egypt is encountering very particular issues and problems – common to developing countries – with regard to electronic commerce. This paper, as it identifies deterrents to electronic commerce in Egypt, hopes to(More)
Samh seeds obtained from Al-Jouf area were ground into flour analyzed and used as a replacement for wheat in the ratio of 10, 20 and 30% for bread and 30, 60 100% for cookies. The rheological effect of the Samh flour on Saudi wheat flour was also studied. The bread and cookies obtained were evaluated physically and by sensory evaluation. The results(More)
The excretion of metabolites by 48 wild-type and mutant strains belonging to various species and genera of aerobic hydrogen-oxidizing bacteria was studied. The cells were grown autotrophically and heterotrophically, and samples were analyzed by gas chromatrographic techniques. The following metabolites were identified and quantitatively determined: acetate,(More)
The removal of copper from aqueous solution by Amberjet 1500H, Amberjet 1300H and Amberlite IRC86 ion exchange resins is described. The Amberjet 1500H shows a remarkable increase in sorption capacity for copper compared to other adsorbents. The adsorption process shows maximum removal of copper in pure aqueous solution for an initial copper concentration of(More)
