Abstract This study is concerned with derivation of quantum relation in a curved space –time . The importance of this study emerges from the use of energy and momentum in many applications. This study use mathematical derivation trend. The research problem is related to the lack of suitable consistent relations for quantum eigen equations in a curved space , beside lack of relations for the special quantum evolution in the interaction model. Therefore this research aims to use the expressio...
Abstract Integrating Administrative and Engineering Sciences, It has profound effect in Enriching both for the good of mankind, As the value management Approach depends on the Organization of Scientific Steps in order to reach the point of balance between quality, cost and time ,Which invited engineers to exploit and apply this approach during the different phases of the project to achieve this balance in all aspects of technical and administrative project in general. And the Proportion of h...
ABSTRACT This Thesis study semi local and hybrid density functional analysis of charge transition levels of native defects in BaF2 and CaF2 structures. The transition levels was calculated from the formation energies corresponding to two defect charge states. The errors arising from the small super cell size effects have been relieved through extrapolating the formation energies to the limit of infinite super cell size. The reliability of the extrapolation method has been verified through th...
Abstract In this dissertation, the one-loop renormalization group equations for the gauge couplings in five and six dimensional models as well as 5D Minimal Super-symmetric Standard Model were derived. We considered different localization of matter fields that is, all fields propagate in the full space-time (bulk case), or some of the fields restricted in the brane (brane case). We studied the evolution of the inverse fine structure constants , which is linked to the gauge couplings constant...
The aim of this study was to determine the nutritive value and safety of media (Sudanese thin porridges). Samples were collected from different locations in Khartoum State. The samples were medidat tamur, millet medida and medidat um genger. The moisture content of Um ginger in Khartoum North, Omdurman and Khartoum was 67.57%, 65.45% and 63.83%, respectively. Date medida was 64.48%, 63.09% and 67.19%, respectively. Millet medida was 67.48%, 65.22% and 66.98%, respectively. Ash content ...
Abstract For the purpose of comparison of the traditional statistical methods used in analysing and classifying data with a vast amount of information and modern statistical methods computerized to obtain relationships and models that help in extracting useful information and support for decision making and hence the problem of study in how Employing this field in the organization, analysis and classification of such a large amount of data, and the establishment of a general rule concerning ...
Abstract: Organ motion in Radiotherapy induce an error in the received dose by the tumour therefore this experimental study conducted at different hospitals in Sudan (Radiation and Isotopes Centres of Khartoum (RICK) and Antalya clinic centre in period of 7 months, from May 2014 to December 2014. The main objective of this study was to detect and measure the periodic physiological prostate motion during external beam radiotherapy (inspiration and expiration) , to accurate and continuous tumo...
This study was carried out to develop probiotic fermented beverages. The commercial strain Bifidobacterium infantis 20088 was used. The growth of the strain and its related physiochemical changes during fermentation was evaluated. The strain survival during refrigeration storage was also examined. In addition the chemical composition of different fermented beverages at initial and maximum growth of the strain were also determined. Growth media were formulated from reconstituted skim mil...
Abstract This study was carried out to investigate the accumulative levels of Pb, Cr, Cd, Ni and Cu in roadside topsoil of three major streets in Khartoum State and the relation between the concentration of these metals and soil chemical properties. The collected roadsides topsoil samples were prepared with an improved closed wet digestion system and the heavy metals concentrations in the extracts were determined using flame atomic absorption spectrometry. The mean concentration ranges of me...
Abstract We give characterizations of isometric shift operators and Backward shifts on Banach spaces with linear isometries between subspaces of continuous functions. We show the inverse spectral theory for the Ward equation and for the 2+1. Chiral model, we also consider the isometric shifts and metric spaces. We also study the Cauchy problem of the Ward equation. We discuss the relative Position of four subspaces in of Hilbert space, with an indecomposable representations ofQuivers on infi...
The main goals of this research were to study the effect of extraction methods, and deep frying process on the Physico-chemical Properties of vitellaria paradoxa ssp. nilotica, beside the chemical composition of shea nuts, the sensory evaluation of potato chips fried in shea butter, groundnut, and their blend oil (1:1) and finally the fatty acid profile of shea butter. The samples were collected from Alradoum area Southern Darfour State – Sudan. Samples were well prepared and kept in d...
The growing complexity of modern software systems makes the prediction of performance a challenging activity. Many drawbacks incurred by using the traditional performance prediction techniques such as simulation, guessing, and depending on previous experience. Moreover, performance assessment and prediction is time consuming activity and may produce inaccurate results especially in complex and large scale software applications. To contribute to solving these problems, we adopt a model-ba...
The excellence of Sudanese Universities and Academic Staff members can be effectively classified by systematic and objective design criteria, which participates in developing the learning outcomes in Sudan. In the first phase of this research, suitable quantitative and qualitative performance evaluation criteria are determined and defined, pairwise comparisons and evaluation forms are designed and exploited in order to get experts opinions/preference on the evaluation criteria that are u...
Today with the development of technology and the trend of the Sudan government, Sudanese Universities convert the manual exam to e exam starting by four Universities(Alnealine University, Open Sudan University ,Alnhda faculty ,International University of Africa) , Despite the increasing numbers of educational institutions that carry out the e - exam, the current practices lack the standard and thus become the need to build a unified model in preparing the number of questions and the met...
Abstract This research deals with one of the applications of spectroscopy, which is the detection of some components of sand and the concentrations of these elements using X-ray fluorescence technology and comparison between them. Where sand samples were taken from Bara north Kordofan region (red-orange, black) from surface and depth (30cm, 70cm). It was found that the elements present on the surface of the red-orange sample are: Silicon (Si), Zirconium (Zr), Thorium (Th), Titanium (Ti), and...
