At thermal energies near stellar conditions, nuclear reactions are sensitive to resonance strengths of the nuclear reaction cross-section. In this paper, the resonance strengths of nuclear reaction were evaluated numerically by means of nuclear reaction rate calculations using a written Matlab code, at the energies of interest in stellar nuclear reactions. The results were compared with standard reaction before and after application of a statistical analyses, to select the best parameters that made theoretical results as close as possible to the standard values. Fitting was made for different temperature ranges up to 10 GK, 0.6 GK and 0.25 GK. The evaluated results showed that as the temperature range becomes narrower, more error is added to the evaluated strengths. A proper strength value based on the most recent measured one suggested the difference of at least one order of magnitude can be solved using a numerical evaluation for energies less than 650 keV.

This research sheds light on an important topic related to the understanding of the Qur’anic expressions and how to deal with them in relation to their meanings and connotations intended by God Almighty and the concept of the term strange among the ancients. Its glossaries, such as earth, sun, air, etc., and the other have vague meanings that require careful consideration and scrutiny in order to reach the exact meanings that God Almighty wanted.
The six names are names developed by grammarians, so some of them counted them as six, which are (your father, your brother, your father-in-law, Hanuk, Fuk, and Dhu). The Arabs, as explained by Sibawayh and the linguists after him, when this name was contrary to the conditions of grammar, and what we follow in the rules of these words is that they are expressed in letters that linguists call (vowels), while phonologists call them (long vowels), which are (alif, waw, Walia).

يرى سقراط ان الحب الحقيقي لا يكون خالصا دون معاناة الالم. وهو لا يكون جديرا بمدارك الحب الصوفي- الالهي دون ارادة وقوة منع وتنفيذ شهوات الحواس البشرية.
كذلك يرى سقراط ان اول مراتب العشق الالهي تبدا بتطهير وتنقية النفس البشرية من كل ما يمازجها من اهواء ورغبات.
فالنفس البشرية تشبه المرأة لا يمكن لها ان تعكس صورة العشق الالهي الاسمى دون ان تكون صافية وصقيلة.
وسقراط يرى ان المعرفة

As for the texts of others, such as Al-Farazdaq, Jarir, and Omar bin Abi Rabi'a, and what is distinctive in their readings was that they were texts corresponding to the reading text, then the reading of Jarir Naqdah and Omar bin Abi Rabi`a was an opposition and Ibn Abd Rabu was scrutinized and Ibn Arabi was an interpretation and al-Mutanabi an explanation, and I found that these in their readings constitute a specificity that must be revealed The way of this research (constructive critical reading by the Arab poet - a critical study -) their poor are critical because criticism is pr

Show MorePoetry, since its early ages, has expressed the poets’ feelings, thoughts, emotions and feelings, and perhaps fear is one of those feelings that poets experienced, especially since fear is closely related to what affects the human soul so that it makes it feel safe and secure or fear and dread, and this is what prompts poets to express about those positions;
Heterocyclic compounds are crucial for medicinal chemistry and the development of therapeutic agents like broad-spectrum antibiotics. This study devised a facile procedure to synthesize novel antimicrobial bicyclic heterocycles from 2-mercapto-3-phenylquinazolin-4(3H)-one. Advanced analytical techniques including 1 H and 13C NMR, elemental analysis, and FT-IR spectroscopy characterized the intricate chemical structures of the products. In vitro assays tested the heterocycles against aerobic and anaerobic bacterial strains using fluconazole and ciprofloxacin as antifungal and antibacterial controls. Results demonstrated the formidable broad-spectrum antibacterial and antifungal activities of the synthesized compounds, with growth inhibition

Additionally, new complexes were formed by reacting Schiff base (K) with metal salts CuCl2·2H2O, PdCl2·2H2O, and PtCl6·6H2O by 2:1 of M:L ratio. New ligands and their complexes were characterized, exanimated, and confirmed through several techniques, including FTIR, UV-visible, 1H-NMR, 13C-NMR spectroscopy, CHN analysis, FAA, TG, molar conductivity, and magnetic susceptibility. These compounds and their complexes were screened against breast cancer cells. It was determined that several of these compounds had a significant anti-breast cancer effec
