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.
In the current study, haemoglobin analytes dissolved in a special buffer (KH2PO4(1M), K2HPO4(1M)) with pH of 7.4 were used to record absorption spectra measurements with a range of concentrations from (10-8 to 10-9) M and an absorption peak of 440nm using Broadband Cavity Enhanced Absorption Spectroscopy (BBCEAS) which is considered a simple, low cost, and robust setup. The principle work of this technique depends on the multiple reflections between the light source, which is represented by the Light Emitting Diode 3 W, and the detector, which is represented by the Avantes spectrophotomer. The optical cavity includes two high reflectivity ≥99% dielectric mirrors (dia

The aim of this study is to improve the permeation of LZL through the skin by preparing as nanoemulsion using various numbers of oils, surfactants and co-surfactant with deionized water. Based on solubility studies, mixtures of oleic acid oil and tween 80/ transcutol p as surfactant/co-surfactant (Smix) in different percentages were used to prepare nanoemulsions (NS). Therefore, 9 formulae of (o/w) LZL NS were formulated, then pseudo-ternary phase diagram was used as a useful tool to evaluate the NS domain at Smix ratios: 1:1, 2:1 and 3:1.
This article will address autoclave design considerations and
manufacturing working with high pressure low temperature
supercritical drying technique to produce silica aerogel. The design
elects carbon dioxide as a supercritical fluid (31.7 oC and 72.3 bar).
Both temperature and pressure have independently controlling
facility through present design. The autoclave was light weight (4.5
kg) and factory-made from stainless steel. It contains a high pressure
window for monitoring both transfer carbon dioxide gas to liquid
carbon dioxide and watching supercritical drying via aerogel
preparation process. In this work aerogel samples were prepared and

Ondansetron HCl (OND) is a potent antiemetic drug used for control of nausea and vomiting associated with cancer chemotherapy. It exhibits only 60 – 70 % of oral bioavailability due to first pass metabolism and has a relative short half-life of 3-5 hours. Poor bioavailability not only leads to the frequent dosing but also shows very poor patient adherence. Hence, in the present study an approach has been made to develop OND nanoparticles using eudragit® RS100 and eudragit® RL100 polymer to control release of OND for transdermal delivery and to improve patient compliance.
Six formulas of OND nanoparticles were prepared using nanoprecipitation technique. The particles sizes and zeta potential were measured

This paper presents mechanical and electrical design, and implementation process of industrial robot, 3-DoF type SCARA (selective compliment assembly robot arm),with two rotations and one translation used for welding applications.The design process also included the controller design which was based on PLC(programmable logic controller) as well as selection of mechanical and electrical components.The challenge was to use the available components in Iraq with reasonable costs. The robot mentioned is fully automated using programmable logic controller PLC(Zelio type SR3-B261BD),with 16inputs and 10 outputs. The PLC was implemented in FBD logic to obtain three different automatic motions with hi

While XAI has been widely applied, prior reviews have not addressed the specific demands of industrial and medical inspection tasks. This paper reviews studies applying XAI techniques to visual inspection across industrial and medical domains. A systematic search was conducted in IEEE Xplore, Scopus, PubMed, arXiv, and Web of Science for studies published between 2014 and 2025, with inclusion criteria requiring the application of XAI in inspection tasks using public or domain-specific datasets. From an initial pool of studies, 75 were included and categorized in

The minimum weight of gravel field or lab sample depends on the nominal maximum particle size. The weight of the sample will always be greater than that portion required for testing. The approximate precision desired for the testing will control the weight of the gravel sample. In this study, gravel sample has been simulated by using multilinear approximated function for Fuller’s curve on the logarithmic scale. Gravel particles are divided into classes according to their medium diameter and each class was simulated separately. A stochastic analysis, by using 100 realizations in s
