أن لعبة كرة السلة في تقدم وتطور مستمر حالها في ذلك حال الألعاب الرياضية الأخرى حيث أن الفضل في ذلك يعود إلى المعرفة بالعلوم المختلفة وكذلك البحث العلمي من اجل تحقيق نتائج متقدمة تنشدها معظم الدول ومنها العراق على الصعيد المحلي والعربي والدولي. ومما لاشك فيه أن متطلبات تطور مستوى نتائج القدرات البدنية في أيُة لعبة مرتبطة بالبرمجة والتخطيط الصحيح للمناهج التدريبية إذ تقودنا هذه الحقيقة إلى إجراء المزيد من الاختبارات بصورة دورية كونها كما أشار جونتربلوم Günter Blume (أداة لإثارة الدافع والتفوق واستمرار التقدم) ( )، ولكي يتم من خلالها الحصول على معلومات دقيقة يمكن استثمار نتائجها لغرض الحكم والتقويم والتوجيه بشكل منتظم. ويعد علم الاختبارات والقياس إلى جانب علم التدريب الرياضي والعلوم الرياضية الأخرى من الضروريات الأساسية التي يجب أن تؤخذ بنظر الاعتبار عند استخدام الوسائل التي من شأنها الارتقاء بالمستوى إلى ما يرضي الطموح مختصرةً في ذلك الجهود والإمكانيات، وقد برزت أهمية هذا العلم من خلال إمكانية التقويم الموضوعي لكل من النواحي البدنية والمهارية والخططية والوظيفية والنفسية والتربوية كمؤشرات للحالة الراهنة، وما يرتبط بها من واجبات العلم الثاني في تقديم الأساليب والطرائق المعتمدة في مناهج العملية التدريبية والارتقاء بها. أن هذا الترابط في الواجبات يساهم بصورة فاعلة في تهيئة السبل أمام التشخيص والتوجيه والتصنيف ووضع المعايير لرصد الجوانب الإيجابية والمحافظة عليها وتطويرها من ناحية وتلافي الجوانب السلبية من ناحية أخرى. وفي ضوء ما تقدم ومن اجل تحديد وتقويم تلك المعايير برز دور الخبراء والباحثين في وضع مجموعة اختبارات وبطاريات خاصة بكرة السلة متميزة بثقلها العلمي لمعرفة قدرات اللاعبين الحقيقية وصلاحية الأساليب والطرائق المستخدمة في التدريب. وبناءاً على ذلك فإن أهمية البحث تتجلى في تحديد المعايير وبصورة دورية لقدرات اللاعبين من أجل تحقيق الارتقاء بالمستوى التدريبي للمدربين والأداء للاعبين نحو الأحسن، وزيادةً على ذلك النهوض بمستوى لعبة كرة السلة العراقية.
This research aims to choose the appropriate probability distribution to the reliability analysis for an item through collected data for operating and stoppage time of the case study.
Appropriate choice for .probability distribution is when the data look to be on or close the form fitting line for probability plot and test the data for goodness of fit .
Minitab’s 17 software was used for this purpose after arranging collected data and setting it in the the program.

... Show MoreExposure of reinforced concrete buildings to an accidental fire may result in cracking and loss in the bearing capacity of their major components, columns, beams, and slabs. It is a challenge for structural engineers to develop efficient retrofitting techniques that enable RC slabs to restore their structural integrity, after being exposed to intense fires for a long period of time. Experimental
investigation was carried out on twenty one slab specimens made of self compacting concrete, eighteen of them are retrofitted with CFRP sheets after burning and loading till failure while three of them (which represent control specimens) are retrofitted with CFRP sheet after loading till failure without burning. All slabs had been tested in a
Test results of nine reinforced concrete one way slab with and without lacing reinforcement are reported. The tests were designed to study the effect of the lacing reinforcement on the flexural response of one way slabs. The test parameters were considered is the lacing steel ratios of (0, 0.0025, 0.0045, and 0.0065), flexural steel ratios of (0.0025, 0.0045, and 0.0065) and span to the effective depth ratios of (11, 13, and 16). Two specimens had no lacing reinforcement and the remaining seven specimens had the lacing reinforcement. Four point bending test were carried out, one of the specimens was tested under the static load applied gradually up to failure and the other specimens were tested under repeated load (5 cyc
... Show MoreThe use of silicon carbide is increasing significantly in the fields of research and technology. Topological indices enable data gathering on algebraic graphs and provide a mathematical framework for analyzing the chemical structural characteristics. In this paper, well-known degree-based topological indices are used to analyze the chemical structures of silicon carbides. To evaluate the features of various chemical or non-chemical networks, a variety of topological indices are defined. In this paper, a new concept related to the degree of the graph called "bi-distance" is introduced, which is used to calculate all the additive as well as multiplicative degree-based indices for the isomer of silicon carbide, Si2
... Show MoreThe 2011 Iraqi Measles Control Campaign had as its aim to improve immunization coverage among young adults' 17-24years and, in the longer term, prevention of measles epidemics. The aim of the study is estimation measles vaccination and revaccination efficacy by evaluate the seroprevalence of antibody and response to reimmunization in young adults. A previously vaccinated 189 young adult medical students were tested for measles specific IgG &IgM pre and post catch-up revaccination by using commercially available ELISA. To assess the seroprevalence of antibody response pre measles reimmunization in previously vaccinated young adults; 45 were found to be seronegative. To differentiate between primary and secondary vaccine failure, anti- mea
... Show MoreTwitter is becoming an increasingly popular platform used by financial analysts to monitor and forecast financial markets. In this paper we investigate the impact of the sentiments expressed in Twitter on the subsequent market movement, specifically the bitcoin exchange rate. This study is divided into two phases, the first phase is sentiment analysis, and the second phase is correlation and regression. We analyzed tweets associated with the Bitcoin in order to determine if the user’s sentiment contained within those tweets reflects the exchange rate of the currency. The sentiment of users over a 2-month period is classified as having a positive or negative sentiment of the digital currency using the proposed CNN-LSTM
... Show MoreEducation constituted one of the fundamental tools that played a pivotal role in consolidating Japanese values and identity following the Meiji Restoration in 1868. This transformation was marked by the issuance of the Educational System Ordinance in 1872, which aimed primarily at building a modern state capable of defending itself. As political and military developments progressed, education increasingly sought to instill the notion that the individual is an integral part of the state and must be willing to sacrifice for its sake. The Kaishō era witnessed the reinforcement of these principles, with growing emphasis on military training—an element that became central to educational policy following the invasion of Manchuria in 1

Show MoreTraditional accounting takes only one dimension (economic) in calculating the value added of the company, and all other aspects (including environmental and social) are neglected, and despite the emergence of Sustainability Accounting and the interest of companies in preparing sustainability reports, these reports are suffering from many problems, including multiple metrics used in measuring companies (cash, quantity and lavish). In addition, these reports may reach dozens of pages in some companies and this causes the problem (information overload) which affects the qualitative properties of accounting information such as appropriate and relative, which requires the need to find a tool that can measure the Sustainability Unit of

It studies the saponification of diethyladipate DA with sodium hydroxide NaOH solution synchronous with separating ethanol from the reaction mixture through an aqueous – organic membrane. The effect of time on some variables such as: permeated ethanol concentration EtOH wt%, separation factor (α), concentration of NaOH solution CB in the reaction medium and the conversion of DA to monoethyladipate (the intermediate product) was studied. It was shown that EtOH wt% and the conversion increased with increasing time unlike CB but (α) showed the existence of maximum value during the time of experiment. The process of reaction assisted by pervaporation
