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.
Lowering the emission, fuel economy and torque management are the essential
requirements in the recent development in the automobile industry. The main engine control
input that satisfies the above requirements is the throttling angle which adjusts the air mass
flow rate to the engine port. Due to the uncertainty and the presence of the nonlinear
components in its dynamical model, the sliding mode control theory is utilized in this work
for the throttle valve angle control system to design a robust controller for this system in the
presence of a nonlinear spring and Coulomb friction. A continuous sliding mode control law

A new application of a combined solvent extraction and two-phase biodegradation processes using two-liquid phase partitioning bioreactor (TLPPB) technique was proposed and developed to enhance the cleanup of high concentration of crude oil from aqueous phase using acclimated mixed culture in an anaerobic environment. Silicone oil was used as the organic extractive phase for being a water-immiscible, biocompatible and non-biodegradable. Acclimation, cell growth of mixed cultures, and biodegradation of crude oil in aqueous samples were experimentally studied at 30±2ºC. Anaerobic biodegradation of crude oil was examined at four different initial concentrations of crude oil including 500, 1000, 2000, and 5000 mg/L. Complete removal of crud

One of the most important problems facing the world today is the energy problem. The solution was in finding renewable energy sources such as solar energy. The solar energy applications in Iraq is facing many problems . One of the most important problems is the accumulation of dust on the solar panels surface which causes decreasing its performance sharply. In the present work, a new technique was presented by using two-axis solar tracking system to reduce the accumulated dust on the solar panel surface and compared it with the fixed solar panels which installed at tilt angles 30° and 45°. The results indicated that the maximum losses of the output power due to accumulation of dust on the fixed solar panels is about 31.4% and 23.1% res

There are many applied Economic studies that have found positive nexus between financial development and poverty reduction in developing countries. Iraq has witnessed an increasing rate of poverty during the period 1980-2010 due to many internal and external factors such as wars, economic sanctions, inflation, a high rate of unemployment, and political and security instability. Therefore, the investigation about the solutions to reduce poverty becomes very necessary, and enhancing the financial development in Iraq is one of these options. This is due to that the financial development could reduce the poverty rates through two channels: the first is direct via the offering of the loans and other financial facilities to the poor, a

This work describes the weathering effects (UV-Irradiation, and Rain) on the thermal conductivity of PS, PMMA, PS/PMMA blend for packaging application. The samples were prepared by cast method at different ratios (10, 30, 50, 70, and 90 %wt). It was seen that the thermal conductivity of PMMA (0.145 W/m.K), and for PS(0.095 W/m.K), which increases by PS ratio increase up to 50% PS/PMMA blend then decreased that was attributed to increase in miscibility of the blend involved. By UV-weathering, it was seen that thermal conductivity for PMMA increased with UV-weathering up to (30hr) then decreased, that was attributed to rigidity and defect formation, respectively. For 30%PS/PMMA, there results showed unsystematic decrease in thermal conduct

The goal of this work is demonstrating, through the gradient observation of a of type linear ( -systems), the possibility for reducing the effect of any disturbances (pollution, radiation, infection, etc.) asymptotically, by a suitable choice of related actuators of these systems. Thus, a class of ( -system) was developed based on finite time ( -system). Furthermore, definitions and some properties of this concept -system and asymptotically gradient controllable system ( -controllable) were stated and studied. More precisely, asymptotically gradient efficient actuators ensuring the weak asymptotically gradient compensation system ( -system) of known or unknown disturbances are examined. Consequently, under convenient hypo
