Because it is obligatory for every Muslim to pay attention to the jurisprudence of his religion in order to achieve goodness thereby

He is guided to the paths of light.

One of the most important topics of Islamic jurisprudence is marriage. Because it relates to the life of every member of society, the engagement is one of the prerequisites for marriage, and whatever is related to what is important is important. It also contains many matters and details, so we wanted to write a study in it that understands its tasks so that the Muslim is aware of his religion.

And let him stay away from situations and customs that contradict our true religion. We have adopted approved books that are widely circulated among the majo

In the field of research in the investment of gas fields, this requires that we first look at the center of the contracting parties in terms of the guarantee means granted to them under the contract, which constitute a means of safety and motivation to enter as major parties in the investment project. In turn, we will discuss the minimum guarantees, which are the most important guarantees granted to each of the two parties to the contract, namely the national party and the investor.

The development of better tools for diagnosis and more accurate prognosis of cancer includes the search for biomarkers; molecules whose presence, absence or change in quantity or structure is associated with a particular tumour or prognosis/therapeutic outcome. While biomarkers need not be functionally relevant, if cell survival, then they could also provide new targets for therapeutic drugs. In recent years attention has been applied to a group of proteins known as cancer testis antigens (CT antigens) [1]. These proteins are products of genes whose expression was normally confined to the testis, yet they are expressed in tumour cells. CT genes are bound to serve a wide array of roles in the testes, which have many highly differentiated cel

يتنامى يوما بعد يوم استخدام السيارات وتتعاضم اعدادها ، فهذا هو عصر السرعة، وخاصة في مجال النقل والمواصلات، والتي تتحقق باستخدام وسائل النقل المختلفة ومن بينها السيارات، وبالتالي اصبحت هذه الوسيلة ضرورية لتحقيق هذه السرعة ومن ضرورات الحياة في انجاز الاعمال.

وتتبارى مصانع السيارات فيما بينها لانتاج انواع السيارات بمواصفات عالية من المتانة والامان والراحة، وفي ذات الوقت اصبحت هندسة الطرق

The difference and pluralism among members of the same society is a fact undeniable and ignored, passed by the Quran, and confirmed by the Sunnah of the Prophet Mohammed in more than one occasion, so that the Apostle r placed a document included in its terms an agreement with the Jews, and recognized the coexistence between Muslims and Jews, which stems from the great principle of a tolerance, which recognizes the rights of others and the freedom to believe what is believed to be right, so it was incumbent upon us, and we live in rivalry repulsion and jealousies to recognize the principle of coexistence with the other, and accept it in accordance with the legitimate controls with pride of belonging to the Islamic religion, in this sense

Staphylococci are common commensals in human beings, yet certain species are pathogenic. Staphylococcus aureus, particularly, is a very virulent human pathogen. The capacity of staphylococci to sense the density of bacterial cell, i.e., quorum, and thereafter respond via genetic modifications is attributable to one primary mechanism known as accessory gene regulator (Agr). Agr's extracellular signal is a peptide that is posttranslationally modified with a thiolactone molecule. Agr is in charge of the upregulation of numerous exotoxins and hydrolyzing enzymes, as well as the downregulation of many colonization determinants, under circumstances of high cell density. This modulation is critical for the scheduling synthesis of virul

Renewal is generally considered an urgent requirement of life, and a section of its continuation, because renewal means that life exists and continues, and just as renewal is in life, renewal is in science, and in this research the issue of renewal in the science of interpretation, and showed through research that renewal in This science was an urgent demand throughout the Islamic ages, as the research showed the necessity of renewal in the material of interpretation, its method and methods, and the researcher presented the opinions of schools about renewal in the interpretation of the Noble Qur’an inferred by living models that refer to their owners.

     The plasma source can restrict the motion of charges that are localizing in the non equilibrium distribution of charge energy and reducing the electrons transport across magnetic field . The electrons & ions motion are controlled by ambipolar electric field and charge–atom collision . the source density for a given electron temperature and a given ion are considered to evaluate the diffusion coefficient . the ambipolar diffusion coefficient and the cross field diffusion coefficient for charge transfer are calculated through magnetized plasma in a uniform magnetic  field , and an approximation ambipolar diffusion coefficient is evaluated. The result, showes how the diffusion process is gradually im

Praise be to God, Lord of the worlds, and peace and blessings be upon our master Muhammad and his family and companions as follows:
     This research examines altruism in the Noble Qur’an objectively. The altruism is a word that permeates selection, preference, presentation, types of gifts, and all other material and moral virtues. It is the highest level of generosity and generosity, provided that the consent of God Almighty is enriched on the consent of others, and that greatness arises in it, and that creation affects On yourself in what does not deprive you of a religion, and it does not cut you off on a path, because the praiseworthy altruism is only in relation to souls, not the disgraced altruism tha

The research addressed the problem of widows that increased recently enormously. The researcher also referred to the perspective of Islam that gave a significant attention for both widows and orphans as powerless groups. Some straightforward example were presented to reflect the actual difficulties that encounter these groups as well as the author proposed number of appropriate ways that mitigate their psychological and physical sufferings such as: the provision of convenience jobs, and the legislation of rule that save their rights. Moreover, the researcher addressed the importance of marrying widows and what these challenges that encounter polygamy in Arab societies, the advantages and disadvantages of polygamy, and discussing all the
