An analytical study of the crossing and throwing steps and the distances of pulling and extending the arm of elite javelin throwers and their relationship to achieve menthe researcherAbstract : The javelin throw event is one of the distinguished events in athletics, and it requires physical capabilities and special movement capabilities in addition to some physical specifications. Approximate or final throwing phase.The importance of research is highlighted by the continuous interest in sports achievements and the continuation of the process of developing them, and the importance of kinetic analysis in revealing the most important weaknesses of shooters, and the importance of biomechanical variables, especially the last throwing steps, the distance of withdrawal and the extension of the throwing arm during the throwing.The research problem revolved around the importance of identifying some numerical values of the biomechanical variables and their relationship to achievement, focusing on the weaknesses that the Iraqi spear thrower suffers from in the pre-throwing stage of force preparation, and working on analyzing these molecules and applying them to improve technical performance.And the failure to use motor analysis and identify weaknesses with high accuracy, in addition to the lack of interest by the trainers in the characteristics of the values of the biomechanical variables affecting each other in order to program their training programs in order to achieve their goals as quickly as possible and with the least effort.The aim of the research is to identify the most important biomechanical variables related to the stage of preparing the force, which is the speed of the last throwing step and the speed of the penultimate scissor crossing step and the decrease between the speed of these two steps and the distance of pulling and extending the throwing arm and the relationship between these variables with the achievement of the Iraqi elite spear throwers.The researcher used the descriptive approach and correlational relationships in her current study because it is appropriate to the nature of the problem of the study. The research community consisted of elite Iraqi players who are advanced in javelin throwing, and their number is (6) shooters. They took a comprehensive enumeration method. The test was conducted on the research sample in the stadium of the College of Physical Education and Sports Sciences / University of Kufa in preparation for the championship. The Iraqi clubs have the third round, giving each shooter six attempts as in the official races, and the best attempt was taken as an achievement for the analysis, and two analysis cameras (CASIO FH13.5) were used at a speed of 120 frames per second, and the analysis was done with the analysis program (Kenova). After analyzing and discussing the results, the researcher concluded that there is a relationship A direct correlation between the length and speed and the distance of the throwing arm with the achievement and an inverse correlation between the steps and the time of the steps and the difference between the two speeds and the distance of the stretch with the achievement.

MRP is a system intended for the batch manufacturing of discrete parts including assemblies and subassemblies that should be stocked to support future manufacturing needs. Due to the useful information provided by MRP it has evolved into a Manufacturing Resources Planning, MRP II, a system that ties the basic MRP system to the other functional areas of the company such as marketing, finance, purchasing, etc. The objective of this research, which was conducted at the State Company for Batteries Manufacturing, is to test the performance of some popular lot-sizing techniques used within MRP II framework. It is hypothesized that the technique which minimizes the total inventory costs does no

An observation with an extreme value on a predictor variable is a point with high leverage. Leverage is a measure of how far an independent variable deviates from its mean. These leverage points can have an effect on the estimate of regression coefficients.
Robust estimation for regression parameters deals with cases that have very high leverage, and cases that are outliers. Robust estimation is essentially a

The paper attempts to find out the elements of picaresque novel in selected English and Iraqi novels. It studies these elements in Henry Fielding’s Joseph Andrews and Adil Abduljabbar’s Arzal Hamad Al-Salim. The paper is divided into four sections. The first is an introduction to the picaresque novel. It gives a definition, a historical background, and the elements of the genre. The second section studies Fielding’s novel focusing on the elements of this type of novel and how it affects the story itself. The paper follows the novel from the beginning to the end showing these elements. The third is dedicated to Abduljabbar’s novel and how the elements of picaresque genre appear in the novel and play an important role in its developm
