(Sudan University of Science and Technology, 2017-11-10)Moringa oleifera (MO) is a pan-tropical, multipurpose tree whose seeds contain high quality vegetable oil (oil content up to 40% by weight). It contains water-soluble proteins that act as effective coagulants for water and ...
-
(Sudan University of Science and Technology, 2017-01-10)We study subnormal and hyponormal Toeplitz operators with extremal problems of Hardy spaces. The compact Toeplitz operators by the Berezin transform on bounded symmetric domains, heat flow and bounded mean oscillation are ...
-
(Sudan University of Science and Technology, 2017-08-30)Phytochemical screening the leaves of Aristolochia bracteodlata revealed the presence of flavonoids, tannins, alkaloids and glycosides. Paper sheets eluted with 15% acetic acid allowed isolation of compounds I and II ...
-
(Sudan University of Science and Technology, 2017-06-11)this study a number of alkoxides of copper(II), Cu(where R is a(OR)primary, secondary or tertiary alkyl group) were synthesized by the reactions of anhydrous copper(II) chloride with sodium alkoxides in 1: 2 molar, the ...
