أهمية البحث اعداد تدريبات الهيت في تطوير القوة الانفجارية وفقا لمؤشر معدل النبض التي تتطلب تكيف الأداء البدني للوصول إلى كفاءة عالية لدى لاعبي الريشة الطائرة. يهدف البحث اعداد تدريبات الهيت في تطوير القوة الانفجارية وفقا لمؤشر معدل النبض لدى لاعبي الريشة الطائرة وكانت مشكلة البحث إن تنوع لأساليب التدريبية واختلاف تأثيراتها يجعلان لاعبي الريشة الطائرة بحاجة إلى إعداد بدني يتناسب مع إمكانياتهم وقدراتهم البدنية ، ومن خلال خبرة الباحث الميدانية لاحظ وجود هبوط في مستوى الاداء اثناء اللعب حيث ارتى الباحث الوقوف عن هذا الهبوط والوقوف على نقاط الضعف الواضحة من القوة العضلية مع تكيف مؤشر معدل النبض التي لم يأخذ دوره وحجمه الحقيقين في عملية التدريب ضمن البرنامج المعدة من قبل المدربين وبأساليبها المختلفة مما ولد ضعفا وتأثيرا في مستوى الأداء لذا ارتأى الباحث دراسة هذه المشكلة للوصول الى نتائج إيجابية حيث استخدم الباحث المنهج التجريبي بتصميم المجموعتين التجريبية والضابطة ذات الاختبار القبلي والبعدي لملائمته طبيعة البحث. مجالات البحث هي المجال البشري لاعبي نادي المحاويل للموسم الرياضي 2024. والمجال الزماني المدة من السبت الموافق بتاريخ 6/1 /2024 الى يوم السبت الموافق بتاريخ 9/ 3 /2024. والمجال المكاني: القاعة الرياضية في النادي المذكور وتم تحديد مجتمع البحث من لاعبي الريشة الطائرة لفئة الشباب للموسم الرياضي2024 وبعدد 12 لاعب، واختيرت منهم عينة البحث بالطريقة العمدية (ن= 10) والتي مثلت نسبة مئوية قدرها (83.33%) وقسمت العينة الى مجموعتين تجريبية وضابطة (ن = 5 لكل مجموعة)، وكانت اجراءات التجانس والتكافؤ للعينة كما تبين في الجدولين 1، 2 اظهرت نتائج تحليل البيانات الإحصائية بين المجموعتين التجريبية والضابطة في الاختبارات البعدية وجود فروق دالة احصائياً في متغيرات البحث لصالح المجموعة التجريبية ، ويرى الباحث إن سبب التطور في نتائج الاختبارين البدنيين للذراعين والرجلين وتكيف معدل النبض في المجموعة التجريبية في الاختبار البعدي إلى فاعلية البرنامج المعد باستخدام تدريبات الهيت الذي عمل على تطوير القوة الانفجارية لعضلات الطرفين العلوي والسفلي واظهرت النتائج الى تفوق ملحوظ بين القياس القبلي والبعدي لتدريبات الهيت في تطوير القوة الانفجارية للمجموعة التجريبية ولصالح القياس البعدي أوصى الباحث الاهتمام بتدريبات الهيت في تطوير بعض القدرات البدنية لدى لاعبي الريشة الطائرة. يخدم البحث الهدف 3 من اهداف التنمية المستدامة (ضمان حياة صحية وتعزيز الرفاهية للجميع في جميع الأعمار). وهذا ما يحقق احد اهداف التنمية المستدامة للامم المتحدة في العراق (الصحة الجيدة).
Insulin resistance is a fundamental feature of obesity, diabetes, and cardiovascular diseases and contributes to many of the metabolic syndrome's abnormalities. It is defined as a subnormal reaction to normal insulin concentrations or a situation in which greater than normal insulin concentrations are necessary for normal response.
The effects of three different additives formulations namely Lubrizol 21001, HiTEC 8722B and HiTEC 340 on the efficiency of VII namely OCP of three base lubricating oils namely 40 stock and 60 stock and 150 stock at four temperatures 40, 60, 80 and 100oC were investigated. The efficiency of OCP is decreased when blended with 4 and 8 wt% of Lubrizol 21001 for all the three base oil types. But it is increased when adding 4 wt% and 8 wt% of H-8722B in 40 stock. While for 60 stock and 150 stock the OCP efficiency decreased by adding 4 and 8 wt% of H-8722B. In the other hand, it is decreased with a high percentage by adding 4 and 8 wt% of H-340 for 60 stock and 150 stock and for 40 stock it is increased by adding 4 wt% of H-340 and decreased
... Show MoreHeart disease is a significant and impactful health condition that ranks as the leading cause of death in many countries. In order to aid physicians in diagnosing cardiovascular diseases, clinical datasets are available for reference. However, with the rise of big data and medical datasets, it has become increasingly challenging for medical practitioners to accurately predict heart disease due to the abundance of unrelated and redundant features that hinder computational complexity and accuracy. As such, this study aims to identify the most discriminative features within high-dimensional datasets while minimizing complexity and improving accuracy through an Extra Tree feature selection based technique. The work study assesses the efficac
... Show MoreThe current study is designed to achieve the goal of early detection of heart disease because it is the main risk of death. Some biomarkers were measured as well as the percentage of the effect of certain risk factors in people with myocardial infarction and heart failure. The study included 40 serum samples from people with heart disease. The effectiveness of the creatine kinase (CK-MB), as well as its temporal and albumin effects, as well as sodium ions in people with myocardial infarction and heart failure, were compared with the control group. as shown below:
-The first group consisted of 25 blood samples from people with myocardial infarction and 15 serum samples from people with heart failure. Blood
... Show MoreBackground: Gray-scale sonography is generally
considered as a first-line diagnostic tool for patient with
suspected acute cholecystitis. It is suggested by gallstones,
Murphy's sign, thickening of the gallbladder wall and bile
sludging, but the specificity of these sonographic findings
are not as high as their sensitivity. Blood flow of the
gallbladder wall is increased in acute inflammation.
Objective: To evaluate the sensitivity and specificity of
power Doppler sonography and compared with conventional
color Doppler and gray-scale sonography in diagnosing
patients with acute cholecystitis.
Type of the study: This was a cross sectional study.
Patients and methods: The study was conducted t
InSb alloy was prepared then InSb:Bi films have been prepared successfully by thermal evaporation technique on glass substrate at Ts=423K. The variation of activation energies(Ea1,Ea2)of d.c conductivity with annealing temperature (303, 373, 423, 473, 523 and 573)K were measured, it is found that its values increases with increasing annealing temperature. To show the type of the films, the Hall and thermoelectric power were measured. The activation energy of the thermoelectric power is much smaller than for d.c conductivity and increases with increasing annealing temperature .The mobility and carrier concentration has been measured also.
The present paper describes and analyses three proposed cogeneration plants include back pressure steam-turbine system, gas turbine system, diesel-engine system, and the present Dura refinery plant. Selected actual operating data are employed for analysis. The same amount of electrical and thermal product outputs is considered for all systems to facilitate comparisons. The theoretical analysis was done according to 1st and 2nd law of thermodynamic. The results demonstrate that exergy analysis is a useful tool in performance analysis of cogeneration systems and permits meaningful comparisons of different cogeneration systems based on their merits, also the result showed that the back pressure steam-turbine is more efficient than other pro

It is an analytical study of the views of a sample of managers in the Iraqi Ministry of Education. The research highlights the contribution that can be made from the knowledge of the theory of business organizations in achieving organizational success. The organizational power of the organization contributes to achieving entrepreneurship in the business environment and achieving a competitive position in the work environment. The research dealt with two variables: the first is the independent variable, the organizational power in its dimensions (Expend Power, Structural Power, Prestige Power). And t
... Show MoreA load-shedding controller suitable for small to medium size loads is designed and implemented based on preprogrammed priorities and power consumption for individual loads. The main controller decides if a particular load can be switched ON or not according to the amount of available power generation, load consumption and loads priorities. When themaximum allowed power consumption is reached and the user want to deliver power to additional load, the controller will decide if this particular load should be denied receiving power if its priority is low. Otherwise, it can be granted to receive power if its priority is high and in this case lower priority loads are automatically switched OFF in order not to overload the power generation. The

The research is important by analyzing the magnitude of the macroeconomic and especially GDP effects of these variables, as well as the economic effects of exchange rates on economic activity. The results of the standard analysis using the ARDL model showed a long-term equilibrium relationship, according to the Bound Test methodology, from explanatory (independent) variables to the internal (dependent) variable, while the value of the error correction vector factor was negative and moral at a level less than (1%).
