I was invited to deliver a research paper on orphan care at the Center for Psychological and Educational Research. So I sought help from God Almighty and began writing a research in which I explained the meaning of the orphan, his condition, and the Holy Qur’an’s care for him. Therefore, I intended for the title of my humble research to be (Caring for the Orphan in the Islamic Perspective), since the papers were mixed up in the time of accidents, disasters, and deadly weapons, all of which reap men more than what we suffer. In this wounded country of ours, with civil wars, sectarianism, and insecurity, research began to solve the problem of orphans at a time when society had become an orphan with no shepherd. When I addressed this topic, another issue came to mind, which is the issue of widows, and it is an issue that is inseparable from the issue of orphans. So how can we We address the problem of the orphan and leave his mother. Therefore, the topic of the research became broader, as I made a special chapter for widows in which I discussed some of the solutions that society can apply in the reality of its life to eliminate this deep problem. I divided my research into two chapters, preceded by this introduction and followed by a conclusion in which I recorded the summary of the research. The most important results I reached.
In the first chapter, I discussed the meaning of the orphan in language and terminology, and the interest of the Holy Qur’an on the subject of the orphan, and the virtue of caring for the orphan. In the second chapter, I discussed the meaning of the widow in language and terminology and her need for care and care. Then I began to solve the problem of the increasing number of widows in society today, and how we can address this major problem. All members of society must cooperate to eliminate this problem until this ordeal is overcome.
Then, at the conclusion of the research, I discussed the most important results and recommendations that I came up with, and I ask God Almighty to grant me success in this humble research of mine and to make it sincere for His honorable face. He is the best Lord and the best Helper.
In this paper, three approximate methods namely the Bernoulli, the Bernstein, and the shifted Legendre polynomials operational matrices are presented to solve two important nonlinear ordinary differential equations that appeared in engineering and applied science. The Riccati and the Darcy-Brinkman-Forchheimer moment equations are solved and the approximate solutions are obtained. The methods are summarized by converting the nonlinear differential equations into a nonlinear system of algebraic equations that is solved using Mathematica®12. The efficiency of these methods was investigated by calculating the root mean square error (RMS) and the maximum error remainder (𝑀𝐸𝑅n) and it was found that the accuracy increases with increasi

Utilizing the Turbo C programming language, the atmospheric earth model is created from sea level to 86 km. This model has been used to determine atmospheric Earth parameters in this study. Analytical derivations of these parameters are made using the balancing forces theory and the hydrostatic equation. The effects of altitude on density, pressure, temperature, gravitational acceleration, sound speed, scale height, and molecular weight are examined. The mass of the atmosphere is equal to about 50% between sea level and 5.5 km. g is equal to 9.65 m/s2 at 50 km altitude, which is 9% lower than 9.8 m/s2 at sea level. However, at 86 km altitude, g is close to 9.51 m/s2, which is close to 15% smaller than 9.8 m/s2. These resu

Investigation of mesomorphic properties of new 1,3,4-thiadiazolines (which are synthesised via many steps in Scheme 1) was carried out in this study. These compounds are designed to have a heterocyclic unit, a carboxylate linkage group and a polar ether chain at the end of the molecule adjacent to the benzene ring, which enhance the dipolar interactions forces (varied from one to eight carbons) to investigate the association properties of their phases. The structure of the target compounds and the intermediates were confirmed by 1H NMR, 13C NMR, mass and FTIR spectral techniques. Polarised microscopic studies revealed that all the compounds in the series exhibited enantiotropic liquid crystalline properties. This was further confirmed using
