The sports field is one of the fields that are concerned with the various methods and methods because of their positive impact on the development of actual training, the investment of the exerted effort in time, and through the follow-up of the researcher in the field and academic field, I noticed that there is a weakness in explosive ability, which affects performance and skill level during training and competition Therefore, the researcher decided to prepare maximum physical exertion exercises according to the anaerobic threshold as a principle of development in many physical and skill variables because good physical performance leads to reaching the best achievements and since the skill of shooting by jumping high - either constitutes a major role in achieving goals during the match that qualifies the team To win, therefore, the role of codified exercises was of great importance in acquiring this skill and mastering it to serve the nature of physical and technical performance and to determine the accuracy of correction towards the target, the aim of the research is to prepare and identify exercises the maximum physical effort according to the anaerobic threshold in developing the explosive ability and the skill of shooting by jumping high - in front of handball Youth, and the researcher adopted the experimental method by designing equal experimental and control groups The research community was determined and the research community was determined by handball players (Specialized School for Giftedness of the Ministry of Youth and Sports) of ages (17-18) years for the 2020 training season, which numbered 14 players, and the exercises were applied maximum physical effort according to the anaerobic threshold on the experimental group for a period of eight weeks With three training units per week, the researcher used the statistical bag (spss) to process the data, and the researcher reached the most important conclusions. The results were a remarkable development between pre and post measurement in developing the explosive ability and the skill of shooting by jumping high - in front of the handball youth for the experimental group and for the benefit of telemetry.

The research seeks to identify the factors affecting the monopoly and the possibility of measuring the phenomenon of economic ( monopolistic profit) accounted for and that the importance of research topic arising from the transformation of the majority of developing countries to the market economy, which represents the image of the capitalist economy, which is a monopoly, a stages that economy in its various forms, whether Market Worldwide sales monopoly or monopoly, which generates absolute monopolistic profits, which more or less affect on the overall economy of those countries than they should study the phenomenon of monopoly and its impact on the economies of those countries that still love to find her site reinforces its pos

Staphylococcus aureus is a common pathogenic agent due to its ability to cause various types of infections, ranging from mild skin infections to sever systemic diseases. One of the most virulence factors of this bacterium is its ability to from biofilms on solid surfaces by anchoring the planktonic cells and by producing a protective layer of extra polymeric substances. Biofilm formation is controlled through many genes. The most important ones are icaA and icaD. Dentures are prosthetic devices that are made of different materials to replace lost teeth. The aim of this study is to examine the ability of different types of denture materials to support the biofilm formation of S. aureus at phenotypic level by detecting ba

Covalent modification of protein by drugs may disrupt self-tolerance, leading to lymphocyte activation. Until now, determination of the threshold required for this process has not been possible. Therefore, we performed quantitative mass spectrometric analyses to define the epitopes formed in tolerant and hypersensitive patients taking the β-lactam antibiotic piperacillin and the threshold required for T cell activation. A hydrolyzed piperacillin hapten was detected on four lysine residues of human serum albumin (HSA) isolated from tolerant patients. The level of modified Lys541 ranged from 2.6 to 4.8%. Analysis of plasma from hypersensitive patients revealed the same pattern and leve
