الخيارات أحدى الأدوات المالية المشتقة التي تشتق قيمتها من قيمة الموجود الأساسي
Underlying Asset، وقد يكون الموجود الأساسي سهما عاديا أو مؤشر أسهم أو عقد مستقبلية سلع أو عقد مستقبلية على أوراق المديونية . وبالرغم من أن الدلائل تشير إلى أن التعامل بالخيارات يعود إلى أوائل القرن السادس العشر الميلادي آلا انه ونتيجة للعديد من الابتكارات التنظيمية  Organizational Innovations في آلية تداول الخيارات والتي ادخلها مجلس سوق شيكاغو للخيارات  (Chicago Board of Option Exchange ,CBOE) في عام 1973 والتي تزامنت مع افتتاح أول سوق منظم للخيارات, فقد شهد التعامل بالخيارات نموا انفجاريا    Explosive  Growth منذ ذلك الحين. وقد جسد نجاح الخيارات كأدوات مالية حديثه افتتاح الكثير من أسواق الخيارات حول العالم .

ويعد تغيير التوزيع الاحتمالي Probability Distribution لعوائد الاستثمار بالأسهم العادية واحدة من أهم مزايا التعامل بالخيارات فضلا عن توفيرها مجموعة كبيرة ومتنوعة من الفرص المتاحة أمام المستثمرين وأتاحة توافيق  Combinationsمن العائد و المخاطرة لم يكن وجودها ممكنا بدون الخيارات.أن هذه الميزة المهمة هي التي حدت بالباحثين لاختبار إمكانية تخفيض مخاطرة الأسهم العادية التي باتت السمة البارزة للاستثمار بالأسهم العادية في معظم الأسواق المالية .

وتعد الخيارات من الموضوعات التي نالت ومازالت أهتماما كبيرا على المستويين الأكاديمي والمهني وأن هذا الاهتمام المتزايد نابع من المتحوطين Hedgers والمضاربين. ونظرا لعدم تداولها في أسواق المال العربية عموما ولحداثة وتعدد مفاهيمها  فان أي ناحية منها بحاجة إلى مزيد من الإيضاح و أولها تعريف الخيارات وأسواقها.

لقد كانت الصيرفة الإسلامية مجرد أفكار في منتصف القرن العشرين تجسدت بتجربة مصارف الادخار المحلية في مصر عام 1963 , ومن ثم في واقع مصرفي أسلامي كانت بدايته مع المصرف الإسلامي للتنمية عام 1975, ومصرف دبي الإسلامي عام 1977, وشهد عقد الثمانينات اتساع المصارف الإسلامية إلى أن وصلت اليوم الى ما يزيد عن 160 مصرف تعمل في مختلف دول العالم واستثماراتها وصلت حوالي 60 بليون دولار.

Abstract
Praise be to Allah, The Lord of the worlds, and peace be upon
Muhammad the master of former and latter people, and peace be upon His

The article considers semantic and stylistic motivations for using obsolete lexicon (historicisms) in the text of a work of art. The specifics of the functioning of this process are presented against the background of the features of the contemporary Russian literary language. Attention is focused on the fact that the layer of obsolete lexical units belongs to a number of nationally specific vocabulary, the development of which forms an understanding of the nature of the actualized language. In addition, it should be noted that the semantics of historicisms is culturally commensurate: the latter is explained by the fact that the deactuation of linguistic units is positioned as parallel to the sociocultural and political changes.

The research study focused on the need to clarify the relationship between the Websites of Iraqi Newspapers and their roles in covering the internal crises in Iraq. The selection of Iraqi websites for the newspapers Al-Zaman and Al-Sabah was adopted as one of the most important media with a wide audience; and as a model of hot news and continuous coverage of those sites since 2003 so far. As a result, this necessitated the emergence of new types of methods of editing and writing news stories related to Iraq.

Consequently, the enormous and rapidly changing amount of Iraq news, the process of preparing and creating news has become a complex industry

Stimulative effect of 10 mW He-Ne laser on the phagocytic activity of human polymorphonuclear leukocytes( PMNs) has been studied in vitro. Normal polymorphonuclear leucocytes were isolated from the human peripheral blood. A mixture of 0.25 ml of Hanks solution, 0.25 ml of serum, 0.25 ml of Candida albicans suspension and 0.25 ml of PMNs suspension was prepared. The samples of mixture of PMNs and Candida were subdivided in 1 ml ependrof tubes and irradiated to He-Ne laser for 1, 3, 5, 10 and 20 min. The diameter of the irradiated area was 0.8 cm. For calculation of Phagocytic index before and after irradiation, the samples were incubated (37°C) at 5, 15, 30, 60 min. The slides of samples were prepared and stained using Giemsa stain. The
