Since the beginning of the corona pandemic, numerous scientific projects have been conducted worldwide to investigate how the new virus can be combated. Researchers are developing various vaccines and drugs at full speed – with varying degrees of success. In this work, silico screening (molecular docking analysis) is performed on twenty natural compounds, which are expected to provide valuable lead molecules and medication to treat a new condition SARS-CoV-2. Our results indicate that out of the 20 compounds on the candidate list, lutein and Polydatin, natural components of fruits and vegetables (especially egg yolk and maize) have shown an excellent performance in our docking studies through a minimum binding energy of − 9.8 kcal/mol also − 7.4 kcal/mol, separately. This indicates their potential for the inhibitory molecular interactions against COVID-19. The main intent of the research is to analyse the protein components and investigate the molecules.
Many studies have shown that faced with an epidemic, the effect of fear on human behavior can reduce the number of new cases. In this work, we consider an SIS-B compartmental model with fear and treatment effects considering that the disease is transmitted from an infected person to a susceptible person. After model formulation and proving some basic results as positiveness and boundedness, we compute the basic reproduction number $ \mathcal R_0 $ and compute the equilibrium points of the model. We prove the local stability of the disease-free equilibrium when $ \mathcal R_0 < 1 $. We study then the condition of occurrence of the backward bifurcation phenomenon when $ \mathcal R_0\leq1 $. After that, we prove that, if the saturation parameter which measures the effect of the delay in treatment for the infected individuals is equal to zero, then the backward bifurcation disappears and the disease-free equilibrium is globally asymptotically stable. We then prove, using the geometric approach, that the unique endemic equilibrium is globally asymptotically stable whenever the $ \mathcal R_0 > 1 $. We finally perform several numerical simulations to validate our analytical results.
Density Functional Theory has been utilized to investigate the electronic and structural characteristics of Aluminium phosphide (AlP). The exchange-correlation potential was calculated using the Generalized Gradient Approximation. The structural, electronic and vibrational features of AlP diamondoids and nanocrystals were investigated using Density Functional Theory at the PBE/6-31(d) level, which included polarization functions. Vibrational modes have been optimized concerning IR intensity, force constants, and lowered masses. In this study there are two components to the vibrational force constant for AlP diamondoids. The first one is distinguished by a reduced mass that is greater than 1 amu and consists primarily of Al-P vibrations that are positioned roughly between 0 and 231 cm-1. The second component has a decreased mass very near to 1 amu and is in the 1228–2400 cm–1 range. It is entirely made up of hydrogen vibrational modes. AlP diamondoids were evaluated with the results of experimental bulk in terms of molecular size-related changes in allocated vibrational frequencies.
Breast cancer (BC) is a genetic disease in the mammary glands' ducts and lobules, with ductal cancers comprising most of the malignancies. Biomarkers can provide an assessment of cancer diagnosis and prediction. The study aims to compare the expression of serum (miR-21-5p) and CA 15-3 expression in the Iraqi population as more efficient biomarkers, then checked MiRNA-21 main characters as a biomarker comparison with (CA15-3) levels. Circulating serum miRNA-21 expression was measured using (the quantitative Real Time-PCR technique) in 50 patients at various stages of breast cancer compared to 27 healthy controls. Meanwhile, CA 15-3 levels were quantified using electro-chemo luminescence immunoassay (ECLIA) methods. The results show the expression of miRNA-21 and the concentration of CA15-3 increased significantly (p>0.01) in patients as compared to control, but the higher median level of MiRNA-21 than of CA15-3. The ROC curve analysis shows that the accuracy, Overall Model Quality, AUC, sensitivity and specificity of miRNA-21 as a biomarker is much higher than the CA 15-3. In conclusion, miRNA-21 may fill the gap that CA 15-3 still lacks in detecting breast cancer at an early stage. Keywords: Breast cancer, microRNA-21, CA15-3, gene expression, RT-q PCR
During 2019-2020, the experiment was conducted in the laboratory of the Department of Field Crop Sciences, Faculty of Agricultural Engineering Sciences - Baghdad University, to investigate the impact of soaking wheat seeds produced during the 2016 agricultural season with three plant extracts (licorice root extract 2%, 4% and 6%, Acadian and Humic(500, 1000, & 1500 mg L-1). Aside from the two control treatments (soaking in distilled water with dried seeds). The results show that the soaking treatment with licorice root extract outperformed the other therapies in conventional laboratory germination, root length, and seedling vigor index (95 percent and 3.42 cm 1207) compared to the two control treatments (soaking with distilled water and dry seeds). While all the Humic and Acadian soaking treatments at the concentrations (500 and 1000) mg L-1 did not significantly differ with the distilled water soaking treatment.The characteristics of standard laboratory germination percentage, root length, coleoptile length and seedling vigor index. Thus, we conclude that soaking wheat seeds with high concentrations of Acadian (more than 1000 mg L-1) leads to a deterioration in the vitality of the seeds. While soaking with licorice root extract enhances the vibrancy and activity of wheat seeds compared to the other extracts used. As a result, we propose soaking the somewhat old and low-vital wheat seeds in a concentration of at least 2% licorice root extract. Keywords: Radicle dry weight, Seedling vigor, seed germination, seed storage.
After a long time that the current account has been governed by Customs and Usages, the legislators began since eighty years, one after another, to organize it, but with some differences. Especially, by organizing this account only in the Bank or Commercial operations. Where, this legal tool can be used by all physical persons, merchants or not, and private and public moral persons, in all operations, Commercial or not. And for that we researched on, by analytical and comparative study, to reach the results that we can draw out from it and to formulate the necessary and suitable recommendations and suggestions to modify the legislations in force to enable everyone to take advantage of the current account.

This study includes an introduction, a preface, and five demands. The preface was in introducing Imam al-Qurtubi (may Allah have mercy on him).The first section was in the testimony of one witness to the wound. In it, Imentioned the sayings of the jurists and their evidence, indicating the correct opinion. The second section was the increase in faith over fifty. Al-Qasama has clarified the sayings of the jurists and their evidence and discussed them The most correct opinion. The third section of establishing retribution By Qasama, it showed the sayings of the jurists and their evidence, and discussed them The most correct opinion. The most correct one is according to the strength of the evidence, and then the study is concluded by a conclusion and references.
Praise be to God, Lord of the Two Worlds, and prayers and peace be upon our master Muhammad and all his family and companions. In this research I dealt with the choices of the scholar Ibn al-Aqrab - may God have mercy on him - who lived in the eighth century AH in the city of Aleppo, In the year (710 AH), I collected his choices and compared them with the eight schools of jurisprudence, and the fatwas of contemporary. where his choices were collected and reached two issues in the khul’ and zihar. The research included an introduction, two chapters and a conclusion. The second topic was the choices of the scholar Ibn al-Aqrab - may God have mercy on him - in the khula and zihar. As for the conclusion, it was in the most important results that I reached in this research.
Objective interpretation is one of the most famous sections of the interpretation of the Noble Qur’an, and it is of three types: either the student takes a specific word in the Noble Qur’an, or he studies a specific subject regardless of the pronunciation, or he takes a surah or a group of verses, which he studies objectively, and I chose the first type of it. So I searched in the Book of God Almighty for the word (livelihood) or (living) and found it found in five verses of the Qur’an. , and God bless.
Imam Abi al-Fadl Wali Al-Din, may Allah have mercy on him, is one of the Shafi’i scholars, distinguished by his knowledge, wisdom of his mind and the broadness of his understanding. This was obvious through the study of "Matn Al-Ghayah Wal-Taqreeb", in which he mentioned his opinion as well as his preferences and choices. The book also contained jurisprudence rules terms, criterions and rules of jurisprudence. He authored the book "Al-Nihayah" by mentioning issues of Shafi’i jurisprudence, with reference to other schools of thought in a few places.
The research includes many objectives to answer a number of questions that revolve around this topic, including Explaining the meaning of right and usufruct and what are the reasons that give an individual the right to usufruct. - Studying the jurisprudence rulings that work to regulate the right to use river water, and clarifying the extent of the interest of Islamic jurisprudence in ensuring these rights. A statement of the legal controls that regulate usufruct. A clarification of what is meant by the partnership contained in the hadiths of the Prophet that call people to the legitimacy of partnership, as it clarifies when an individual has the right to exploit that partnership, and what are the controls for benefit in the event of partnership, and how to sustain this benefit. - A statement of the legal position on the use of river water, the extent to which it is organized and guarantees the rights of individuals in this aspect, and what are the stages this regulation has gone through, with an explanation of some legal articles that regulate the right of usufruct. Explanation of the extent of compatibility and difference between Islamic jurisprudence and legal jurisprudence on the issue of the right to use river water. - Restricting to the two most important rights for the use of river water, namely, the right to drink and to drink..
In this research, a well-known Shafi’i jurist is shed light on, namely, Judge Abu Ali Al-Farqi, who died in the year 528 AH. I found them many, so my study was limited to what he mentioned in the chapters on marriage only, and my methodology in writing was the comparative approach, where I mentioned the opinions of the jurists from the different Islamic schools, open to the opinion of the judge Al-Fariqi, with the evidence for each saying, with a discussion of the evidence, and a statement of the most correct ones. God grants success.
This study dealt with the Jurisprudential issues that consist of three parts according to Shafi’is in Al-Bayan book by Al-Omrani (dead 558 AH) in the book of Taharah and its impact on the fatwas of the contemporaries, a comparative study, because Imam Al-Omrani (may Allah have mercy on him) was an ascetic and pious Imam, a benevolent scholar, well-known for his jurisprudence and principles, speech and grammar. He was born in Yemen, and they called him the Sheikh of the Shafi’is, and the Sheikh of the people of Yemen. He mentioned in his book Al-Bayan, which is one of the important books of the Shafi’is, the most important three aspects in this book, and it is known that the aspects differ from the sayings, because these words are the words of Shafi’i (may Allah have mercy on him). There are two important sayings in this respect; that is, the old saying and the new one. While concerning the aspects, they represent the opinions of the companions of Al-Shafi’i that are based on its origins and rules. These may be their diligence sometimes not based on its origins and rules, and this is not from the doctrine, but is attributed to its owner. Therefore, the researcher selected four issues in the book of “Al- bayan” by Al-Omrani(may Allah have mercy on them) in the book of Taharah, which is related to water, and knowledge of the other sayings of the doctrine that agreed with those aspects of the Shafi’is. Keywords: (jurisprudence, three aspects, Shafi'i, water, the book of the statement, its impact, fatwas of contemporaries).
This study showed what was mentioned in the description of the reward and what was added to it in the Noble Qur’an . The researcher tried to shed light and meditate on what was mentioned in the Holy Qur’an regarding the description of reward. It is found that most of what is said about “reward” is described by its greatness, generous، ungrateful and good. As for what is added to the reward, it has been added to the benefactors, the workers, the believers and the reformers, and to the noun connected (min) the interpreter with what follows it for the doers of good. So that the researcher tried to identify the implications of the description for the above-mentioned، benefiting in all of that from the sources of language and interpretation. The research took place in two demands، the first relates to the description of the reward، and the second with what the reward is added to it. Thus, the study invoked the Qur’anic texts related to these two demands and searched in the sources of language and interpretation for the reasons and indications related to them. As for the introduction that the researcher presented، in which he explained the main idea and division of the research.. Then came the conclusion that the researcher reached the most important findings and results..
This research studier the duration of Elaa and its Judgment in Islamic law. The importance of this research is shown when a man neither wants to marry a woman nor he let her marry another man. He swears not to approach her. He doesn't her as divorced nor married. The purpose behind the Elaa is to do harm to the wife. Even muslims did Elaa too. But God prevented it and gave the husband a duration so that he may think again and not to rush. A Fter that if he thinks that it is better to leaves this harm awm away, he can teave. And if he thinks it is better to devorce, he can devorce. God limited the duration in Four months. So anyone who swears to Elaa for Four months or less, he doesn't need to wait for the end of it. Because the duration of Elaa ends before the time limit or in the time limit. Waiting for four month and ten days should be in the time of Elaa Because only after the duration of Elaa the wife can demand to raise the case to the Judge. If the wife has no right for demanding without Elaa. For the demanding from the husband to reverse his decision should be after four months. Another thing is that doing harm by stopping sexual inter course less than the duration limit.
