نمیة القوة الانفجاریة باستخدام تدریبات الأثقال بطریقة الصعود والھبوط وتأثیرھا في تحسین بعض المتغیرات البیوكینماتیكیة والأداء الفني لمھارة قفزة الیدین الأمامیة على جھاز منصة القفز الحدیثة
...Show More Authors

من خلال ملاحظة الباحثتين الميدانية لمستوى الأداء الفني لمنتخب ناشئات القطر بالجمناستك لمهارة قفزة اليدين الأمامية على جهاز منصة القفز الحديثة لاحظن وجود مشكلة تكمن في ضعف هذا الأداء والذي يؤثر على بعض المتغيرات البيوكينماتيكية لهذه المهارة مما يؤدي إلى عدم أداء المهارة بالشكل الصحيح ، وتعزو الباحثتان ذلك الضعف إلى قلة الدفع بالرجلين والذراعين . لذا ارتأت الباحثتان إجراء هذا البحث الذي يهدف إلى تنمية القوة الانفجارية باستخدام تدريبات الأثقال بطريقة الصعود والهبوط للتعرف على تأثيرها في تحسين بعض المتغيرات البيوكينماتيكية والأداء الفني لمهارة البحث المختارة ، وكان من أهداف البحث التعرف على تأثير استخدام هذه التدريبات في تنمية القوة الانفجارية لدى اللاعبات ، وقد افترضت الباحثتان عدة فروض كان منها إن هنالك فروقاً ذات دلالة إحصائية بين نتائج التقويمين القبلي والبعدي نتيجة تنمية القوة الانفجارية باستخدام تدريبات الأثقال بطريقة الصعود والهبوط ولصالح التقويم البعدي ، وعليه كان المنهج المستخدم في البحث هو المنهج التجريبي وشملت عينة البحث لاعبات منتخب ناشئات القطر بالجمناستك بأعمار ( 10 – 12 سنة ) والبالغ عددهن ( 6 لاعبات ) ، وقد استغرق تطبيق المنهج التدريبي ( 3 أشهر ) بواقع ( 3 وحدات ) أسبوعياً أي بمجموع ( 36 ) وحدة تدريبية طوال مدة البحث ، وقد استنتجت الباحثتان عدة استنتاجات كان من أهمها أن التدريب بالأثقال بطريقة الصعود والهبوط يؤدي إلى تنمية القوة الانفجارية وان تنمية القوة الانفجارية يؤدي إلى تحسين بعض المتغيرات البيوكينماتيكية والأداء الفني لمهارة البحث المختارة .

...Show More Authors

 The present research was performed to study the qualitative and quantitative composition of epiphytic algae on the aquatic host plant Ceratophyllum demersum L. Four sites in Tigris River, at Wassit Governorate were covered, during the seasons of Autumn 2017, winter 2018, Spring 2018, and Summer 2018. The study also included measuring the physiochemical parameters (temperature of air and water, pH , water level, EC, salinity, TDS, TSS, dissolved oxygen,  BOD5, alkalinity, total hardness, calcium, magnesium, total nitrogen, total phosphourus). The total number of species of epiphytic algae was145 species, 98 species belonging to Bacillariophyceae, followed by 27species of class Cyanophyceae, 19 species of class Chloroph

Minimizing error in robot arm based on design optimization for high stiffness to weight ratio
...Show More Authors

In this work the effect of choosing tri-circular tube section had been addressed to minimize the end effector’s error, a comparison had been made between the tri-tube section and the traditional square cross section for a robot arm, the study shows that for the same weight of square section and tri-tube section the error may be reduced by about 33%.

A program had been built up by the use of MathCAD software to calculate the minimum weight of a square section robot arm that could with stand a given pay load and gives a minimum deflection. The second part of the program makes an optimization process for the dimension of the cross section and gives the dimensions of the tri-circular tube cross section that have the same weight of
