The research abstract included introduction and the importance of the research, also included display of the problem represented by weakness for the players when performing some of the basic skills in badminton and the shuttle not reaching to the back corners of the court which gives the player the opportunity to win through applying the pressure on the opponent and make him away from the control center(T) which definitely required level of a collection muscular strength contributed in performance perhaps this related to a number of reasons related with weakness in physical changes especially explosive and characterized by speed forces for the badminton players and be acquainted with them and knowing the extent of their effect in performance, based on this the researcher resorted to study the effect of the training units of falling(deep) jump to develop the explosive and characterized by speed forces for the badminton players. The research problem is exclusive by lack of the coaches attention in perfect way to develop the explosive and that characterized by speed forces on which the basic skills of badminton and the reason of the improvement occurred for the experimental community comes as a result of using the independent variable for training units of the falling(deep) jump which effected actively on the players' performance. The researcher has used the experimental method and the research sample was chosen from the young players certified by the Iraqi badminton central union of age groups(14-16) years old affiliated to Al-Athori club amounted (6) players. Physical Education Original Research Paper The research objectives: Setting training units of falling(deep) jump. Identifying the effect of falling(deep) jump training units to improve the explosive and that characterized by speed forces for badminton players Identifying the effect of falling(deep) jump training units on some of functional changes. Identifying of the research The introduction and importance of the research practicing the sport training leads to functional changes in the organs of the body as whole and as a result of practicing the training for along time and regular and rationed method, there occurred functional adaptabilities in various organs of the body in general and especially in heart organ, but these functional adaptabilities occurred either as peripheral or central changes and the central adaptabilities are known that occurred inside the heart vascular system which are as a result of practicing the regular and rationed sport training for long periods which are a collection of factors and psychological changes which effect on the heart muscle ability to obtain blood and pumping it to provide the blood with (oxygen and energy) for the operating muscles and amongst these factors the heart pulse rate the number of the beat also. Upon this concentrated and via the researcher scientific attempt to explore modern training units alternatives via using the falling (deep) jump in light with the kinetic performance paths of its basic skills and using them in means of developing the collection of contributing muscles towards developing the operating muscles in skillful performance and the second importance this study participating in it , is to draw the coaches attention for updated training units on which the training programs depended to develop its physical features of badminton as alternative for other classical training units, in this it is considered constructive study of the coaches work and their training programs and from it could access sound planning state to promote the physical and skillful aspects of the young players and to develop the game and expand its popularity in our beloved Iraq. The objectives: 1-Setting the falling(deep) training units. 2-Identifying the effect of falling(deep) jump training units to improve the explosive and that characterized by speed forces for badminton players Identifying the effect of falling(deep) jump training units on some of functional variables. The research hypotheses: 1-There are differences of statistical significance among the pre and post-tests results for the control and experimental groups the explosive and characterized by speed forces for the badminton players in favor of post-tests. 2-There are differences of statistical significance among the pre and post-tests resulted from some of functional changes of badminton players in favor of post-tests.
Comparison is the most common and effective technique for human thinking: the human mind always judges something new based on its comparison with similar things that are already known. Therefore, literary comparisons are always clear and convincing. In our daily lives, we are constantly forced to compare different things in terms of quantity, quality, or other aspects. It is known that comparisons are used in literature in order for speech to be clear and effective, but when these comparisons are used in everyday speech, it is in order to convey the meaning directly and quickly, because many of these expressions used daily are comparisons. In our research, we discussed this comparison as a means of metaphor and expression in Russia

Show MoreThis study aims to measure and analyze the direct and indirect effects of the financial variables, namely (public spending, public revenues, internal debt, and external debt), on the non-oil productive sectors with and without bank credit as an intermediate variable, using quarterly data for the period (2004Q1–2021Q4), converted using Eviews 12. To measure the objective of the study, the path analysis method was used using IBM SPSS-AMOS. The study concluded that the direct and indirect effects of financial variables have a weak role in directing bank credit towards the productive sectors in Iraq, which amounted to (0.18), as a result of market risks or unstable expectations in the economy. In addition to the weak credit ratings of borr

A set of climatic data from 60 years (1960–2022) was analyzed. Sand storms in Iraq are a silty sand mature arkose composed of 72.7% sand, 25.1% silt, and 2.19% clay; the clay fraction in dust storms constitutes 70%, with a small amount of silt (20.6%) and sand (9.4%). Dust and sand storms (%) are composed of quartz (49.2, 67.1), feldspar (4.9, 20.9), calcite (38, 5), gypsum (4.8, 0.4), dolomite (0.8, 1.0), and heavy minerals (3.2, 6.6). Increasing temperatures in Iraq, by an average of 2 °C for sixty years, have contributed to an increase in the number of dust storm

So that, in this work, enhancing heat transfer of phase change material is studied experimentally for in charging and discharging processes by the addition of high thermal conductive material such as copper in the form of brushes, which were added in both PCM and air sides. The additions of brushes have been carried out with different void fractions (97%, 94% and 90%) and the effect of four different air velocities was tested. The results indicate that the minimum brush void fraction gave the maximum heat transfer in PCM and reduced the time

Show MoreIn this study water-soluble N-Acetyl Cysteine Capped-Cadmium Telluride QDs (NAC/CdTe nanocrystals) using N-acetyl cysteine as a stabilizer were prepared to investigate the utility of quantum dots (QDs) in distinguishing damaged DNA, (extracted from blood samples of leukaemia patients), from intact DNA (extracted from blood samples of healthy individuals) to be used for biosensing application. Based on the optical characterization of the prepared QDs, the XRD results revealed the formation of the NAC-CdTe-QDs with a grain size of 7.1nm. Whereas, the SEM test showed that the spherical size of the NAC-CdTe-QDs lies within 11~33nm. NAC-CdTe-QDs have superior PL emission properties at of 550nm and UV-Vis absorption peak at 300nm.
