Abstract Infertility is the most widespread and considered as one of the most important unappreciated health problems, particularly in developing countries and about 10% of women failure to achieve a normal pregnancy. This study was conducted to estimate plasma FSH, LH and PRL among infertile Sudanese women. The study included one hundred and fifty women participate in this study and divided into three groups according to the age of participant, group (1) (35- 37 ) years included 44 women, g...
ABSTRACT EEG (Electroencephalography) allows eliciting the mental state of the user, which in turn reveals the user emotion, which is an important factor in HMI (Human Machine Interaction). Researchers across the globe are developing new techniques to increase the EEG accuracy by using different signal processing, statistics, and machine learning techniques. In this work we discuss the most common techniques that can yield better results, along with discussing the common experiment steps to ...
Abstract This dissertation investigates the issues of guidance for pilgrims and how to make it more suitable for groups of pilgrims who navigate in unfamiliar areas. The dissertation will explore how to provide aid to pilgrims in crowded places by developing a pilgrim tracking and identification system using mobile phones that use NFC technology. The proposed system will provide education to pilgrims to guide them throw the Hajj journey. The proposed system will provide instructions regardin...
Abstract The aim of this study was to synthesize and characterize carboxymethyl cellulose (CMC) from Phoenix dactylifera L. )date palm( leaves by etherification reaction using sodium mono chloroacetic acid (MCAA) and sodium hydroxide. The optimum reaction parameters were found to be 55 ⁰C, 30% sodium concentration, 3g MCAA/1g cellulose and 4 hours reaction time to give 0.77 as the highest degree of substitution (DS). FTIR shows that successful isolation of cellulose and the synthesized CMC...
Abstract In this research, the running of quarks masses and flavor mixing in five dimensional standard models has been studied. The evolution properties of quark mass and flavor mixing are performed for the one-loop renormalization group equations in the five dimensional standard model. It is found that the five dimension model has a significant effect on the running of the fermion masses, including both quark and lepton sectors. We quantitatively discussed these quantities for R −1 = 1 Te...
Abstract Sudanese software enterprise which categorized as small enterprises need frameworks and models for process improvement . Capability Maturity Model integration (CMMI ) which is designed for large scale enterprise is not suitable for Sudanese enterprise and need to be customized to suit small enterprise . The current study aims to investigate software process improvement in Sudanese software enterprise and to customized process improvement. Capability Maturity Model integration (CMMI ...
Savings and Credit Cooperative Societies (SACCOs), like other financial institutions, own critical assets that must be protected against attackers even as the threat landscape continue to persist. This study provides a solution to SACCOs by determining security risk exposure index (SREI) based on ISO/ 27001 standards. The objectives of the study were to determine the critical security risks factors affecting Selected SACCOs based on ISO 27001 standards, to design a model for computing th...
ABSTRACT The indiscriminate use of antibacterial agents has led to one of the largest recent global health problems which is the emergence of bacterial resistance. The present study was aimed to investigate the antimicrobial and antioxidant activity of ethanolic extracts of the two medicinal plants; Rosmarinus officinalis L. and Thymus vulgaris L.on Escherichia coli (E.coli). Antibiotic susceptibility test was applied against E.coli urinary isolates using Chloramphenicol, Gentamycin, Amoxici...
Abstract The electrical property of noble mineral ( platinum( 58 680 sample and semiconductor 586 821were studied , at temperatures up to 100C0, 373 Kelvin. It was found that the temperature increases mineral resistivity and decreases it is conductivity ,the resistance and conductivity f or the mineral we found to be equal to R = 106.3 Ω and σ = 0. 01176 respectively . The resistance and conductivity for semiconductor were also obtained . It was found that increasing temperature decreases ...
Abstract The main objective of this research is to implement an enterprise system integration using an enterprise service bus (ESB) in Sudan. The research questions are; what framework to be used to complete the integration? And what are the mechanisms that will be used to make sure that the integration process is successful? Finally, how to choose the workflow engine and what are the criteria for the choice. To achieve the research objectives, different approaches to integrate enterprise sy...
ABSTRACT In an academic setting, it is important for students to be well informed about their academic status and progress regularly. All first year students are provided with school catalogs which hold information about their majors and the courses required by them to pass for them to obtain their particular degrees. Students are given these catalogs only once and many of them tend to misplace them after a few semesters. Hence, they lose information on the requirements they need to obtain a...
ABSTRACT In the world we live in today, the reduction in data generally has seen a great rise. This is because of the numerous advantages that comes with working with smaller efficient data instead of the original large dataset. With this analogy, we can adopt Dimensionality reduction in computer science emphasizing on reducing computer memory in order to have more storage capacity on a computer. An example of this would be to reduce digital images which are then stored in 2D matrices. Dimen...
Abstract Mobile telecommunications such as Global System for Mobile Communication ( GSM ) are now well established globally and users rely heavily on the convenient communications it provides. The level of security provided by GSM is superior to its predecessors and is more than adequate for the majority of users. However, some users in the areas of government, defense or business require more security over and above that provided by the GSM standards and by standard GSM equipment. In a GSM n...
ABSTRACT American University of Nigeria (AUN) has many web application used every day both by students and faculty. For students, faculty and other staff to know about a course or department; they have to visit the AUN website and they can only have little information about them. This problem is faced by students, faculty and visitors that want know about the school of information, technology and computing in the American University of Nigeria. SITC is the second largest school in AUN and it...
Abstract Improvements in the benefit of CT have been so dramatic that a tendency exists to the overuse. CT is a diagnostic imaging modality giving higher patient dose in comparison with other radiological procedures. While the benefits of CT exceed the harmful effects of radiation exposure in patients, increasing radiation doses to the population have raised. The main objective of this work was to find an optimization approach to minimize the radiation dose to adult patients undergoing CT ex...
