The Potential of Establishing Technology Computer Aided Design Industry: Africa - Sudan As a Case-Study A. Osman, Ashraf; B. Abdel Nab, Amin; El-Azhary, Ismail Very-Large-Scale-Integration (VLSI) Integrated-Circuit (IC) designs have steadily grown in their capacity and complexity through the years. The need for technology simulations using technology computer-aided-design (TCAD) tools have become an essential part of design success. The TCAD simulations facilitate process optimization, highlight device performance tradeoffs, enable worst case analysis, and reveal device defects and weakness. Microelectronics higher education in African universities focuses mainly on the chip/circuit design instruction. Virtually little or no emphasis is applied to grow students TCAD simulation skills. This paper discusses the potential of African educational institutes of becoming the supplier of qualified TCAD simulation engineers for future African IC industry and/or worldwide VLSI job market. The African universities are encouraged to emphasize on establishing frameworks that would include TCAD simulation research and development into their curriculums and motivate students to venture the VLSI design and automation fields. This would enable African graduates to exploit the microelectronics job market worldwide and establish TCAD industries within Africa to industrialize African job market.

The Key Performance Indicator for Five Construction Projects in Khartoum State: Case Study M. Hamadan, Rabab; S. Hassan, Awad; Y. Mohammed, Salma; M. Lemhi, Arwa; A. Elgany, Tawasol; M. Ahmed, Rooa Performance measurement is continuous observing and period follow-up of the project achievements which achieved by the specified cost, time, quality and specifications required to satisfy the owner and customer., this study aimed to identify the performance measurement indicators that affect the project and verify that, the means of follow-up and monitoring are used probably to transfer resources to the project system. To verify that, we based on the criteria and equations of the indicator’s measurement according to the methodology of (KPI GROUP 2000) .It was applied to five housing projects in Khartoum State., then application of standards and equations are applied and the results were analyzed which indicated that the reasons of unsatisfactory results are due to the absence of follow-up and monitoring means, interpreted in exchange rate and insufficient planning and scheduling. In order to verify the company's experience with these concepts and how to calculate the completion rates, a field survey was conducted as a second part, then a questionnaire distributed to several companies’ sector in Khartoum State. So, the descriptive analytical method which is based on the study of reality and phenomenon was used and implemented to the targeted sample study in a company which included the project manager or planning manager according to their scientific degrees, then data was analyzed using the statistical analysis program( package 2019), so most important results were appeared which represented in the absence of advanced means of monitoring and lack of knowledge of the concept or application of performance measurement indicators.

Bio-Treatment of an Acidic Industrial Wastewater: Tana Explosive Factory A. Yousof, Yousof; H., Khalid,; K. Abdalla, Babiker ABSTRACT-Tana is one of the Sudanese Military industries. Manufacturing different types of chemical i.e. (TNT, DNT, and MNT). The pH of the acidic wastewater is 1.7 was mixed together with 10% sodium hydroxide lye and neutralized under agitation in neutralizing tank. After neutralization the pH of water reached the value of 6.In this study anew bio treatment is applied to treat acidic wastewater by using moringa oleifera leaves after grinding and mixing in a tank the result indicated that significant increase in pH from1.7 to5.8 in 3 hours, and with 10%added sodium hydroxide (NaOH) pH value reached 6 that without salt sedimentation and low cost of treatment. The Moringa Oleifera leaves showed good treatment properties especially when used for acidic wastewater of pH value (1.7). Moringa Oleifera leaves can raise pH value to (5.8) in three hours. It is highly recommended that realistic visibility study must be carried out to design and apply the manufacture of the tablets of Moringa.

Potentiality of In-house Treatment for Khartoum State Medical Wastes Case study: Khartoum Breast Care Center (KBCC) M. A. Hassan, Eshtiag; F. Bashir, Nagwa As a result of the growing number of hospitals in Khartoum state, huge quantities of medical waste have been produced. Proper handling and treatment are urgently needed in a way that ensures the safety of the individual and society. This study is a simple assessment for an already existing treatment unit by using HAZOP study. The treatment unit is located in Khartoum Breast Care Center (KBCC). A brief review is presented about the amount of waste generated in Khartoum State hospitals and briefing about HAZOP. The assessment and analysis proved that the autoclaving process is safe, uncomplicated, does not require a lot of labor, and most importantly, the treatment is easy to handle. Compared to the medical waste generated by each hospital, autoclaving process is suitable and convenient size wise and operational wise. Some environmental and operational adjustments have been recommended
