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

The presence of residual antibiotics in water results in the development of antibiotics resistant genes. The available wastewater treatment systems are not capable of removing such antibiotics from sewage. Thus, antibiotics need to be removed before the discharge of wastewater. Adsorption is among the promising techniques for the wastewater treatment to aid the removal of a wide range of organic and inorganic pollutants. The present work is a contribution to the search for an economical method for the removal of low concentrations of amoxicillin (AMX) from water by adsorption on water treatment residue, WTR, taken from a local drinking water facility. The chemical composition and the adsorptive characteristics of the material were first

Text science presented a set of criteria to make the text essentially a project to create

The Arabs took care of the Arabic language, collected it, and set standards governing it; This is for fear of melody, in order to preserve the language of the Noble Qur’an from distortion, after many of those who are not fluent in Arabic entered Islam; There were many reasons for setting linguistic standards, but although scholars set these standards, we see them often deviate from them, as well as the language’s departure from these restrictions that they set, because language cannot be restricted, as it is subject to the law of use

The Arabs took care of the Arabic language, collected it, and set standards governing it; This is for fear of melody, in order to preserve the language of the Noble Qur’an from distortion, after many of those who are not fluent in Arabic entered Islam; There were many reasons for setting linguistic standards, but although scholars set these standards, we see them often deviate from them, as well as the language’s departure from these restrictions that they set, because language cannot be restricted, as it is subject to the law of use.

عرف الإنسان اللؤلؤ منذ عصورما قبل التاريخ ، حيث كان يجمعه من الأصداف التي كانت تلقي بها الأمواج على الساحل . و لم تُمارس مهنة الغوص إلا في مرحلة لاحقة لم يحدد تاريخها .

In terms of each party's contribution to the common venture, partnership felt in several categories. It would be a complete partnership, that is, one in which all partnership, both capital and service; It could be an arrangement like the commenda (Arabic : Mudãraba , muqãraba , girãd) in which one party supplied the capital and the other service .
In Malikite and Hanaifite Law, It would take the form of a labor partnership, that is, one in which the only investment on the part of all its members was their skill or labor. In this last category of partnership, the captil itself considered solely or primarily of the labor of the partners.

The Arabic medicine books have emphasized that the Arabic Pediatricians in their scientific career ,who searched in Various aspects concerns with pediatric , as well as that some  medical results and phenomena emphasized some data related to this subject . Which operates at the present time attention and concern towards human and in public and towards Pediatricians in special.

This research contained from an introduction that interpreted the Arabic medical heritage in progressing medicines in Europe then it mentioned the prominence  Arabic pediatricians . the researcher depended on references and sources which will the reader had found through research.
