(Sudan University of Science and Technology, 2-08-2015)The subject of this work is a radiological study of environmental radionuclides along the River Nile branch in northern Sudan. Measurements of natural and some artificial (man-made) radionuclides in sediments, water ...
-
(Sudan University of Science and Technology, 2003-01-01)We show a discussion of the following questions: for a given real –valued function (i) ( f ∈ ∞ Rn L ) there can not be bi-Lipschitz homeomorphism determinant, det Dφ f = φR : n →n R such that the ...
-
(Sudan University of Science and Technology, 2003-01-01)We show a general approach to infinite dimensional non-Gaussian Analysis which generalizes the work to measures which possess more singular logarithmic derivatives . This frame work also includes the possibility to handle ...
-
(Sudan University of Science and Technology, 2003-01-01)We describe the boundedness of linear operators from the weighted Bergman spaces ,under some conditions on the weight function ,into a general Banach space by means of the growth conditions at the boundary of certain ...
-
(Sudan University of Science and Technology, 2003-01-01)This descriptive case control study of 60 subjects were conducted to Khartoum Atomic Energy Hospital Laboratory. Measurement of thyroid hormones and the enzyme creatine kinase were determined in (20) control subject which ...
-
(Sudan University of Science and Technology, 2003-01-01)This dissertation consists of four chapters. In chapter one we present a brief introduction to fixed point theory and the most important result in the fixed point theory is the famous theorem of Brouwer which says that the ...
-
(Sudan University of Science and Technology, 2003-01-01)This dissertation discusses the method of characteristics and waves normals used in finding the solutions of hyperbolic partial differential equations. It is then applied to study the nature of atmospheric pressure. ...
-
(Sudan University of Science and Technology, 2003-01-01)This dissertation consists of three parts The first one discusses the types of linear integral equations and gives some examples of theire solutions using the degenerate kernels , the difference kerenls and Schmidts ...
-
(Sudan University of Science and Technology, 2003-01-01)We present the characterization of subalgebras and Douglas subalgebras. We show the existence of one point maximal antisymmetric sets for H + C and subalgebras of L containing H. we completely characterize compact ...
-
(Sudan University of Science and Technology, 2003-01-01)This thesis discusses some problems in mathematical finance driven by Brownian motion, which is the basis for a large part of the modern probability theory that has been mentioned in the first chapter and which plays a ...
-
(Sudan University of Science and Technology, 2003-01-01)We first give a survey of conformal mappings on the complex plane. Then a general study of cavitation is given. This is followed by a discussion of tree streamlines in various two dimensional examples of liquid flow ...
-
(Sudan University of Science and Technology, 2003-01-01)In wide class of weighted Bergman spaces , we construct inevitable non-cyclic elements ,these are then used to produce z- invariant sub spaces of index higher than one generated non trivial bilaterally invariant subspaces ...
-
(Sudan University of Science and Technology, 2003-01-01)It is shown that Banach space of certain density contains an unconditional sequence of cardinality and a separable super reflexive Banach space admits a continuous surjection on each of its subspaces. We introduce a new ...
-
(SUDAN UNIVERSITY OF SCIENCE AND TECHNOLOGY, 2003-01-01)This studay was conducted on Sidir Plant,s leaves , this Plant grows wildly in Sudan and in many countries in the world. Sidir belongs to the family Ramancea. Latin name “Ziziphus spina- christi” and it called locally ...
-
(Sudan University of Science and Technology, 2003-02-01)The purpose of this research is to assess the drinking water quality in the Nile East district including Aidbabiker, Alshigla, Altakamol, Albashir, Albarakat, Darelsalam, and Almaigoma. The study was carried out during ...
-
(Sudan University of Science and Technology, 2003-04-01)Drugs are essential for human life and are of prime importance to the safety of patients. In this work, the stability of Metronidazole benzoate, in the solid form, towards direct sun light and temperature was ...
-
(Sudan University of Science and Technology, 2003-06-01)This study is bused on a Dirichlet form theory. We characterize the weighted composition operators their adjoints and compactness of some functional Hilbert spaces. We show the Fredholm properties of some Toeplitz operators ...
-
(Sudan University of Science and Technology, 2003-07-01)Stochastic models for educational planning for Sudanese universities are designed in this thesis to analyze the efficiency of dynamic analysis of educational parameters utilized. The methodology of this study was introduced ...
-
(Sudan University of Science and Technology, 2003-08-01)The detection of current based on the change of polarization direction of the laser beam with in fiber looped by the current carring conductor has been studised theoretically and experimentally using a single mode fiber ...
-
(Sudan University of Science and Technology, 2003-08-01)Xanthenes are important group of compounds characterized by their certain biological activities. These compounds can be synthesized from the corresponding aldehydes. The carbonyl group in aldehydes is one of the versatile ...
