The aim of the project is to develop parallel approaches for Gaussian Elimination Methods that are used in linear programming to solve linear module systems. Most of these models are time-consuming when executed and processed in the sequential microprocessor computers. During the project, we try to decrease this time and increase the efficiency of the algorithm for the Gaussian Elimination Method, through developing parallel methods appropriate to be executed on MIMD type computers. In this paper, three algorithms were suggested for paralleling a developed algorithm of Gaussian Elimination Method and a comparison was made between the three algorithms and the original. As we have been able to accelerate the three parallel methods and the speedup was one of the following: Speedup =

We describe an artificial Ant Colony Optimization (ACO) capable of solving the graph coloring problem. Ants of the artificial colony are able to generate successively shorter feasible tours by using information accumulated in the form of pheromone trail deposited of the edge of the colonies ant. Computer simulations demonstrate that the artificial ant colony is capable of generating good solutions. It is the successful use natural metaphor to design an optimization algorithm. We generated randomly 20 graphs of 100 nodes, the performance is a best than any other available heuristic techniques such that genetic algorithm and others, so the average of coloring of a graphs is less than any other algorithms. We achieve the goal the goal of the problem

The aim of the project is to develop parallel approaches for both the simplex that are used in linear programming to solve linear module systems. Most of these models are time consuming when executed and processed in the sequential microprocessor computers. During the project, we try to decrease this time and increase the efficiency of the algorithm for the two methods simplex, through developing parallel methods appropriate to be executed on MIMD type computers. In this paper, three algorithms were suggested for paralleling (a developed algorithm and a comparison was made between the three algorithms and the original. This comparison is included in second section. In general, the practical results and the suggested programs for these new algorithms proved to be better in performance than their analogues that are executed in computers of sequential processor in view of the two elements of execution time and algorithm time.

Magnesium is an essential mineral for the human body, and its deficiency causes multiple detrimental cellular and organ dysfunctions. The issue of its routine supplementation is debatable, but there is no doubt that in case of depletion, it should be supplemented. Because of its role in inflammatory and autoimmune conditions, its serum levels have been frequently analyzed. However, its role in rheumatological diseases has been barely investigated. The present review aims to screen the literature for well-designed studies in which magnesium was supplemented to cure rheumatological conditions. SciELO, PubMed, and Web of Science databases were screened between 1966 and April 2024 for the literature on this topic. Only one study fulfilled the inclusion criteria and demonstrated that 300 mg/day of oral magnesium reduced insulin resistance in rheumatoid arthritis patients. The lack of studies on this subject shows that additional studies are required to understand the causal relationship between magnesium supplementation and disease treatment.
