The Middle East and North Africa (MENA) region is undergoing significant socio-political and developmental transition. Although interest in corporate social responsibility (CSR) in the region is growing, little research has addressed corporate social responsibility education and its potential impact. CSR has an important role to play in the socio-economic development of the Middle East and North Africa due to the volatility and developmental needs of the region. Recent research has highlighted that the vitality of the institutional environment and the needs of multiple stakeholders in CSR are not necessarily consistent with the notion of CSR in the West. This book compiles conceptual, contextual, and empirical research that addresses the concepts of CSR, ethics, and sustainability education in the MENA region, with a special emphasis on how educators can bridge to the Giving Voice to Values approach. This book presents a much-needed portfolio of articles from authors based in Egypt, Morocco, the Sultanate of Oman, Qatar, and the United Arab Emirates (UAE), highlighting first an overview of the topic and its corresponding publications in the MENA region, then presenting several exemplary cases related to ECSRS application in various countries.
Book relates to the speed control of an induction motor introduced intelligent methods such as Fuzzy Logic Control (FLC), Artificial Neural Networks (ANN), Adaptive Neural Fuzzy Inference System (ANFIS) and Optimization Techniques such as Genetic Algorithm (GA), Sequential Quadratic Programming (SQP) and Particle Swarm Optimization Algorithms(PSO).The results showed that the PSO-PI controller can perform with an efficient way for searching for the optimal PI controller. Comparison study among fuzzy logic, neural network, Adaptive Neural Fuzzy Inference System, genetic algorithm, sequential quadratic programming and particle swarm optimization controllers are performed. These methods can improve the dynamic performance of the system in a better way.The PI-PSO controller is the best method based on integrated of time weight absolute error (ITAE)criteria which presented satisfactory performances and possesses good robustness (no overshoot, minimal rise time, steady state error almost to zero value). A comparison study has been done between selected methods and some other technique which showed that the proposed controller has setting time less than other methods by 40%.
Diabetes mellitus is a complex of metabolic disease characterized by hyperglycemia, diminished insulin production, impaired insulin action, or a combination of both resulting in the inability of glucose to be transported from the blood stream into the tissues, which in turn results in high blood glucose levels and excretion of glucose in the urine, The cell functions involved in the action of insulin receptor binding enzyme and transporter activities are controlled by membrane properties . Fatty acids composition of membrane phospholipids are affected by the composition of the dietary fat .Changes in the fatty acids composition of erythrocyte membrane, which are easily accessible cells, reflects changes in that of membrane phospholipids of less accessible tissues . The fatty acids composition of cell membrane can influence membrane associated phenomena such as the interaction between insulin and its receptors. Thus it is from interest to study the relationship between cell membrane phospholipids fractions and their role in insulin action, also to study the role of omega-3 fatty acids in reducing oxidative stress in diabetic rats.
The structure, function, and composition of the basement membrane of glomerular capillaries of the mammalian kidney have been extensively studied, in light of the membrane's frequent involvement in renal diseases. A novel mathematical model, based on the Fiber Matrix Theory, was developed to describe the dynamics of permselectivity of the glomerular capillary barrier using mainly its hemodynamic and morphometric variables. The glomerular basement membrane was represented as a homogeneous 3D meshwork of fibers of uniform length (L ), radius (R ), and packing density (N v) and characterized by a local Darcy permeability. The model was appropriate for simulating in vivo fractional clearance data of neutral test macromolecules from an experimental rat model. We believe that the L and R best-fit numerical values, characterizing a glomerular basement membrane geometrical arrangement, may represent diagnostic measures for renal function in health and disease. That is, these parameters may signify new insights for the diagnosis of some human nephropathies and possibly may explain the beneficial effects and/or sites of action of some pharmacological modifiers.
