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.
Abstract
In this work, diabetic glucose concentration level control under disturbing meal has been controlled using two set of advanced controllers. The first set is sliding mode controllers (classical and integral) and the second set is represented by optimal LQR controllers (classical and Min-, ax). Due to their characteristic features of disturbance rejection, both integral sliding mode controller and LQR Minmax controller are dedicated here for comparison. The Bergman minimal mathematical model was used to represent the dynamic behavior of a diabetic patient’s blood glucose concentration to the insulin injection. Simulations based on Matlab/Simulink, were performed to verify the performance of each controll
... Show MoreThe present paper deals with experimental investigation of the performance of air cooled split air conditioner, with evaporative water mist pre cooling to increase the cooling capacity and reduce the consumption power under hot and dry climate. This investigation considers how the performance can be enhanced by using water mist to pre-cool ambient air entering the condensers by adiabatic cooling process which depends on the ambient air wet bulb temperature; as well the condensing temperature and condensing pressure will be decreased accordingly. So the cooling capacity would be increased and consumption power would be decreased, consequently the energy ratio, EER would be improved. The performance of air cooled air conditioner with water
... Show MoreTillage tools are subject to friction and low-stress abrasive wear processes with the potential deterioration of the desired soil quality, loss of mechanical weed efficacy, and downtime for replacing worn tools. Limited experimental methods exist to quantify investigate the effect of wear-resistant coatings on shape parameters of soil-engaging tools. ASTM standard sand/rubber wheel abrasion and pin-on-disk tests are not able to simulate wear characteristics of the complex shape of the tillage tools. Even though the tribology of tillage tools can be realistic from field tests, tillage wear tests under field conditions are expensive and often challenging to generate repeatable engineeri
Many condensed polymers [A1-A7] were prepared via reaction of (Ethylenediaminetetraacetic acid = EDTA), with different prepared imide-diamines by modification [ modification of amino acids and antibiotics (B1- B7)] Imide-diamines were prepared by chlorination of L-amino acids such as [ L-Histidine, L-Alanine, L-Valine, L-Glycine and L-Aspargine ] or selected antibiotics such as [Cephallixine monohydrate and Amoxilline ] with thionyl chloride at 0°C, then reacted with ammonia to obtain imidediamines [B1-B7] . The physical properties of all prepared condensed polymers [A1-A7], new prepared diamines [B1-B7] were studied and characterized by FT -IR spectroscope to certify the structural formulas. The thermal analysis (TGA, DTA) were studied, a
