  • A Framework for Establishing a Semantic Web in a University Web Site: A Case Study University of Gezira

The  advent  of  the  World  Wide  Web  (WWW)  technology  has  yielded  an 
escalating demand for managing data, information and knowledge effectively. Recently, 
various research groups started delivering results from their semantics based on search 
engines,  however,  most  of  them  are  in  their  initial  stages.  Apparently,  the  current 
websites  represent  the  biggest  global  database  that  lacks  the  existence  of  a  proper 
semantic structure. Therefore, it makes it difficult for the machine  to understand the 
information provided by the users. Unfortunately, this shortcoming is inherited in all 
universities web sites. Indeed, some of  these  websites place the information incorrectly, 
untidy  and incomplete, which leads to a delay in ranking the university. University of 
Gezira  is  one  of  the  universities  websites  that  has  this  problem.  University  website 
ranking  plays  a  key  role  for  quality  assessment  in  terms  of  usability  and  visibility 
factors.  The aim of this thesis is to design a framework for establishing a semantic web 
in a university web site in general and taking  University of Gezira  as a particular case. 
This  can  be  accomplished  by  organizing   the   information   in   conceptual   spaces 
according to its meaning by using Semantic Web and ontology. The main objective of 
applying the concept of the semantic web is to enhance the ranking of the university.  In 
this research, Microsoft Visual Studio 2010 is used to design the web pages, and SQL 
server 2008 is used to host the database. Protégé and Microsoft Visio are used as tools 
for  the  ontology. The website that is designed  according  to web 3.0 standards  will have 
clear presentation  of information  and the information itself will be current. We expect 
that  the  usability  of  the  website  will  increase  to  it  is  maximum  level,  and  the  site 
organization  will  be  enhanced  to  the  highest  level. Also  the  following  metrics  can  be 
enhanced to their maximum level: contents, compatibility, using file naming rules, using 
folder naming rules. Thus the ranking of the University website will be enhanced.

  • Chemical and Sensory Characteristics of Jam and Nectar Processed from some Sudanese Guava Genotypes

 

This research is justified by the need of using different Guava genotypes, in the region of Singa and Khartoum city for the
processing of jam and nectar. The experiments were conducted during 2009/10 and 2010/11. Selection of Guava genotypes was
based on high yield and good fruit quality, that recognized by Guava growers and field survey. In the present study, various
genotypes of guava fruits from Khartoum and Singa city were used in jam and nectar processing and evaluate their chemical
analysis (pH, total soluble solids, total acidity and vitamin C) as well as the sensory analysis. The total soluble solids of jam that
processed from both genotypes were in the range 66.8-68.8 brix. The acidity and pH of jam that processed from Singa and
Khartoum were in the range of 19.6 – 23.9 and 3.3 – 5.0, respectively. Nectar-Vitamin C of both genotypes of Singa and
Khartoum was in the range 12.0 – 197.3 mg\100g, while the total soluble solids were 1.8 – 5.4. Depend on the results of
chemical and sensory analysis; it can be made of jam and nectar from these selected guava genotypes. Most panelists preferred
the jam made using genotype Singa 2 and nectar processed form genotype Singa 4. Also most panelists preferred the jam
processed from the genotypes Khartoum 3 and nectar processed from genotype Khartoum 7.

  • Developing software program to simulate blended material properties

Textiles are much more than means of keeping the human body  warm. and portect it from weather changes. They are also means of decorating our homes and improving our working environment. For industrial application, they compete with glass, wires, plastics, ceramics and all forms of sheet materials. As for clothing they compete with plastics and leather and as for carpets they compete with stone, wood and other flooring materials.In this study the properties of materials commonly used for textile, were graded into four grades (excellent, good, fair and unsatisfactory).  Each grade was given special weight, in order to convert a qualitative properties into quantitative. Fabrics were also classified into classes according to their end uses (eg:dressing fabric, army dressing, curtains, furniture, etc). Specific criteria was set for each class and ten properties were tested for each class of fabric..

            C-language was used to build Software package capable to select the desired material that meet the specific purpose to estimate properties of fabric produced from blended materials and to choose an optimum combination satisfy the consumers in terms of quality as well as price. . It is found that by using this software the user can predetermine the properties of any fabrics produced for any season. The user of this software also can estimate the properties of any fabric produced by a blend of any fibres. Choices are available when the price of the product is a crucial factor. By using this software the test which require more than 24 hours can be carried out within a few minutes and number of instruments will no longer be used.

  • In silico Analysis of Single Nucleotide Polymorphisms (SNPS) in Human Factor VIII Gene

F8 gene is extremely large (186 kb) and consists of 26 exons. F8 is located on the long arm of the Xq28 region of the X chromosome. Mutations in this gene can occur at diverse sites in a variety of types, such as structural variation and sequence variation. Single Nucleotide Polymorphisms (SNPs) are the most abundant sequence variations encountered in a genome playing a major role in understanding of the genetic basis of many complex human diseases, the nonsynonymous SNPs (nsSNPs) are known to be deleterious or disease-causing variations because they alter protein sequence, structure, and function. F8 gene plays a major role in hemophilia A. A computational-based (In Silico) analysis has been done to evaluate the phenotypic effect of nsSNPs in human Out of total of 6021 SNPs in the F8 gene, 1276 were nsSNPs, 626 were missenes mutation and 650 duo to nonsense mutation, 54 occurred in the 3'utr and 24 occurred in 5'utr Among the predicted nsSNPs, (rs371422922), (rs370369511), (rs1800288), (rs368808810) and (rs373079141), were identified as deleterious and highly damaging by the SIFT and PolyPhen programs. The protein structural analysis of these amino acid variants was performed using (I mutant and PHD), where Modeling of these amino acid substitutions prepared by Project hope. From a comparison of the stabilizing residues of the native and mutant proteins, we propose that these variants could be an important candidate for hemophilia A, caused by the F8 gene and other pathological condition.
