Science occupies great importance in Islamic thought. Science and learning are considered an essential part of Islamic teachings, and this importance appears in several aspects,Among them is thatScience as a means of understanding religion :Science is a means of understanding the teachings of the Islamic religion. Islam encourages thinking and rational research to understand the Holy Quran and the Sunnah of the Prophet, enabling Muslims to direct their lives and actions in accordance with the directives of their religion,And also to encourageResearch :Islam encourages scientific research and the use of reason in understanding the nature of the universe and God’s signs in it. Muslims are encouraged to study the natural and social sciences and all fields that are useful in developing human knowledge. Science and community development :Islam views science as playing a crucial role in the progress and development of society. It encourages the use of science and technology in the service of humanity, in improving living conditions and promoting social and economic progress, science and piety :Islam views science as a means to achieve piety, that is, a close connection with God and living according to His teachings. The search for and acquisition of knowledge is a form of worship, and Islam promotes people’s understanding that achieving knowledge leads to deeper piety, knowledge, and individual and collective excellence. :Islam encourages the pursuit of knowledge and achieving excellence in its field. It glorifies academic achievement and individual and collective skills as means of serving society and making positive contributions, science and justice :Islam promotes the use of science to achieve justice in society. The Islamic religion expects those with knowledge to contribute to serving justice, ensuring the rights of individuals, and achieving balance in society. In Islamic thought, science is linked to religion and lifeAlyumiaIt encourages Muslims to use science as a means to achieve personal well-beingAnd socialAt the same time To serve God and his creation. This is what Imam Al-Ghazali argued in the content of the research, where:Not all knowledge is science. For example, our life experiences do not include direct observation and practical activity, which do not go beyond the pure description of facts and processes, and which do not go beyond monitoring their external aspects only. That Work is all the activities that a person practices, whether physical or mental, with the aim of production in the institution in which he works, whether governmental or private, or the work may be in a personal profession or craft. The concept of work in Islam: Work is everything that brings benefit to the believer, and this benefit may be material, worldly, or moral in the hereafter. Work has great importance and great status in Islam, and through it the Muslim obtains a great reward and reward, as it is considered worship and compliance with the commands of God Almighty, so through it Life flourishes, the country is prospered, and stability is achieved for the individual and society as a whole. Work in Islam is considered a type of jihad for the sake of God, and its goal is not just to collect money, but rather it is an act of worship that brings goodness to the Muslim, and what is required of him is to strive hard in life seeking the doors of sustenance. And to adhere to God’s limits and not disobey His commands, as good deeds are what guarantee a good life and strength for a person.
The objective of the current research is to find an optimum design of hybrid laminated moderate thick composite plates with static constraint. The stacking sequence and ply angle is required for optimization to achieve minimum deflection for hybrid laminated composite plates consist of glass and carbon long fibers reinforcements that impeded in epoxy matrix with known plates dimension and loading. The analysis of plate is by adopting the first-order shear deformation theory and using Navier's solution with Genetic Algorithm to approach the current objective. A program written with MATLAB to find best stacking sequence and ply angles that give minimum deflection, and the results comparing with ANSYS.
In this research various of 2,5-disubstituted 1,3,4-oxadiazole (Schiff base, oxo-thiazolidine , and other compounds) were synthesized from 2,5-di(4,4?- amino-1,3,4-oxadiazole ) which use quently synthesized from mixture of 4-amino benzoic acid and hydrazine in the presence of polyphosphorus acid. The synthesized compounds were characterized by using some Spectral data (UV, FT-IR, and 1H-NMR).
Free vibration behavior was developed under the ratio of critical buckling temperature of laminated composite thin plates with the general elastic boundary condition. The equations of motion were found based on classical laminated plate theory (CLPT) while the solution functions consists of trigonometric function and a continuous function that is added to guarantee the sufficient smoother of the so-named remaining displacement function at the boundaries, in this research, a modified Fourier series were used, a generalized procedure solution was developed using Ritz method combined with the imaginary spring technique. The influences of many design parameters such as angles of layers, aspect ratio, thickness ratio, and ratio of initial in-

Genetic Algorithm (GA) technique has been applied to solve power engineering optimization problems giving better results than classical methods. This paper shows the application of GA for optimal sizing and allocation of a Static Compensator (STATCOM) in a power system. STATCOM devices used to increase transmission systems capacity and enhance voltage stability by regulate the voltages at its terminal by controlling the amount of reactive power injected into or absorbed from the power system. IEEE 5-bus standard system is used as an example to illustrate the te

Mechanical instrumentation of root canals cause an irregular layer of debris, known as the smear layer. As a result, several studies reported that preferring the removal of the smear layer. Objective: To study the influence of the energy (100 mJ) of Erbium, Chromium: Yttrium Scandium Gallium Garnet (Er,Cr:YSGG) laser at short pulse duration (60 μs) on smear layer removal of apical third after using Photon induced photoacoustic streaming technique. Materials and methods: Eighteen straight single-rooted mandibular premolars were used. The roots length were uniform to 14mm from the anatomic apex and
... Show MoreThe simulation of passively Q-switching is four non – linear first order differential equations. The optimization of passively Q-switching simulation was carried out using the constrained Rosenbrock technique. The maximization option in this technique was utilized to the fourth equation as an objective function; the parameters, γa, γc and β as were dealt with as decision variables. A FORTRAN program was written to determine the optimum values of the decision variables through the simulation of the four coupled equations, for ruby laser Q–switched by Dy +2: CaF2.For different Dy +2:CaF2 molecules number, the values of decision variables was predicted using our written program. The relaxation time of Dy +2: CaF2, used with ruby was
... Show MoreA novel demountable shear connector for precast steel-concrete composite bridges is presented. The connector uses high-strength steel bolts, which are fastened to the top flange of the steel beam with the aid of a special locking nut configuration that prevents bolts from slipping within their holes. Moreover, the connector promotes accelerated construction and overcomes the typical construction tolerance issues of precast structures. Most importantly, the connector allows bridge disassembly. Therefore, it can address different bridge deterioration scenarios with minimum disturbance to traffic flow including the following: (1) precast deck panels can be rapidly uplifted and replaced; (2) connectors can be rapidly removed and replaced; and (
