Numerical results of Crank-Nicolson scheme on unsteady nano fluid under the effect of Prandtl, Mixed Convection, and Magnetohydrodynamics

In this paper, we are interested in the numerical results on the temperature and velocity profiles over a sphere of unsteady nano fluid by dealing with the effect of Prandtl, mixed convection, and magnetohydrodynamics. We first employ the boundary layer theory to establish the continuity, momentum, and energy equations. We further solve those differential equations numerically by using the finite difference scheme of Crank-Nicolson and Thomas algorithm for the iteration technique. The temperature and velocity profiles are established graphically for the variations of Prandtl, mixed convection, and magnetohydrodynamics. The velocity profile decreases when the variations of Prandtl numbers increase. Moreover, the velocity profiles increase when the variations of mixed convection and magnetohydrodynamics are increased. The temperature profiles are decreased for all variations of Prandtl numbers, mixed convection and magnetohydrodynamics

Optimal Control of HIV-1 Spread in Combination with Nutritional Status and ARV-Treatment

HIV-1 is a virulent virus, it has the ability to easily spread the virus. This study aims to optimally control the spread of the HIV-1 virus with SIPA (Susceptible-Infection-PreAIDSAIDS) model by using nutritional status and ARV-treatment. Assessment of nutritional status is carried out on people with HIV/AIDS (ODHA). The results showed that the control in the form of nutritional status and ARV-treatment was able to reduce the infected subpopulation. Routine assessment of nutritional status can form balanced nutrition for ODHA. ARV-treatment works by reducing the amount of HIV viral load, so that HIV infection cannot cause disorders of the immune system

s-SCMM: A Simplified Software Configuration Management Model for Software Services in Public University

Software Configuration Management (SCM) is a process that supports Software Development Life Cycle (SDLC), which benefits project management, development activities, maintenance activities, quality assurance activities, and the end users of the software product. However, findings from series of interviews have proven that SCM is difficult to operate and to be implemented by the practitioners in public universities specifically in Malaysia. Some of the SCM activities could be aided by using the SCM automated tools, however not all practitioners opted that due to inflexibility of the tools. Theoretical and empirical study have identified and revealed the current practices, success factors, essential elements, and components of SCM that were used frequently and beneficial among software practitioners. The empirical study also found that the main components of s-SCMM are process, SCM tool, and human.  The s-SCMM was proposed and developed by considering the main components: process, tools, human, and success factors. The s-SCMM model was validated through expert review. As the result, a Simplified SCM Model (or s-SCMM) was proposed and developed to help the execution and implementation of SCM in public university environment. The s-SCMM model is simplified by focusing on change management, version control, system building, and release management. Therefore, s-SCMM will become a platform to assist total implementation of SCM in organization. By using this model, the preparation and usage of SCM artefacts could become more effective, efficient, and systematic

The Effect of HRM Practices on Organizational Performance: A Survey of Malaysian State Sports Councils’ Employees

Organizational performance can be evaluated through the effectiveness of human resource management (HRM) practices implemented in the organization. However, the problem of improper and misguided implementation of HRM practices causes conflict between employees and organizations, influencing organizational performance. This study examines the effect between HRM practices and organizational performance among Malaysian State Sports Councils’ (MSSC) employees by adapting the Social Exchange Theory. This survey involved a total of 280 MSSC employees. This research instrument consists of 35 items that measure HRM practices and organizational performance. Data were analyzed using regression analysis. Based on the findings, there is a significant and direct effect between HRM practices and organizational performance among MSSC employees. In conclusion, the organization’s excellent structure of HRM practices enables employees to commit to work and perform tasks according to the organizational goals. Future researchers are recommended to extend the sample of study to other sports organizations or other public and private organizations in measuring HRM practices and organizational performance

Immune and bacterial toxin genes expression in different giant tiger prawn, Penaeus monodon post-larvae stages following AHPND-causing strain of Vibrio parahaemolyticus challenge

Acute Hepatopancreatic Necrosis Disease (AHPND), a disease caused by Vibrio parahaemolyticus (V-PAHPND), kills Penaeid shrimps worldwide, resulting in severe economic losses during aquaculture. To further understand how Penaeus monodon post-larvae (PL) respond towards infection of this pathogenic bacterium, the expression of several important immune and bacterial toxin genes in three stages of P. monodon PL (PL15, PL30 and PL45) upon V-PAHPND challenge, were determined. A 20-hrs challenge test with 2.7 x 10(7) cfu ml(-1) of V-PADPND resulted 81, 65 and 1.7% mortality respectively for PL30, PL15 and PL45, indicating that PL30 was most vulnerable to V-PADPNEP The immune response of shrimp PL at this stage was robust, with Toll-like receptor (TLR), prophenoloxidase (proPO), lysozyme (lyso) and penaeidin (PEN) augmented approximately 10.7, 4.7, 6.5 and 3.2-fold, respectively. The expression initiated at one hour post-infection (h.p.i), peaked at 16 h.p.i and 20 h.p.i, and decreased at 18 h.p.i, indicating the crucial involvement of these immune related genes in the defence and recovery of the first-line defence mechanisms during V-PADPND infection. This work also revealed that toxR gene represents a good indicator gene for Vibrio detection whereas PIR A, for V-PADPND pathogenicity determination of P. monodon. Overall, these findings provided novel insights into the immune response and V-PADPND No susceptibility of different P. monodon PL stages during infection, with outcomes potentially useful in enhancing the application of health therapy and biosecured aquaculture practices to minimize the damaging risk of AHPND towards sustainable production of P. monodon
