The aim of the research is to evaluate the performance of the international investment portfolio using the return and risk model to rationalize the investment decision by making a comparison between the available investment tools and choosing the best investment alternative, depending on the appropriate methods and tools to measure performance. To achieve the objectives of the study, the researcher obtained data for 40 us government treasury bonds whose maturities ranged between one and three years, and they were divided according to priority of maturity, into four equal groups, each group of 10 bonds, then computed the difference factor for each group and measured the correlation coefficients between them, and study forming an investment portfolio consisting of two groups of these groups (diversification) that are the least connected, and arriving at the conclusion that the investment portfolio consisting of the bonds of the first and fourth groups together in equal proportions (distributing the amount allocated to the purchase of bonds between the two groups equally) is the best performance (the lowest coefficient of variation), and can improving the performance of this portfolio by increasing the relative weight of the bonds of the fourth group (the lowest coefficient of variation) by 86% of the total value of these two groups that make up the portfolio.

Research summary
تهدف هذه الدراسة إلى تقييم أداء المحفظة الاستثمارية الدولية لعينة من سندات الخزينة الحكومية الأمريكية باستخدام نموذج العائد والمخاطرة لترشيد القرار الاستثماري. قام الباحثون بجمع بيانات لـ 40 سندًا تتراوح تواريخ استحقاقها بين سنة وثلاث سنوات، وقسموها إلى أربع مجموعات متساوية. تم حساب معامل الاختلاف لكل مجموعة وقياس معاملات الارتباط بينها. توصلت الدراسة إلى أن المحفظة الاستثمارية المكونة من سندات المجموعتين الأولى والرابعة بنسب متساوية هي الأفضل أداءً، ويمكن تحسين أدائها بزيادة الوزن النسبي لسندات المجموعة الرابعة إلى 86% من إجمالي قيمة المحفظة. توصي الدراسة بالاستثمار في السندات في ظل الظروف الاقتصادية الحالية واستخدام الأساليب الإحصائية لتقييم أداء المحفظة الاستثمارية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في مجال تقييم أداء المحافظ الاستثمارية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة اعتمدت على بيانات من فترة زمنية محددة (2020)، وهذا قد لا يعكس تقلبات السوق على المدى الطويل. ثانياً، الدراسة ركزت فقط على سندات الخزينة الحكومية الأمريكية، وكان من الممكن توسيع نطاق البحث ليشمل أنواع أخرى من السندات أو الأصول المالية لتحقيق نتائج أكثر شمولية. ثالثاً، الدراسة لم تأخذ في الاعتبار تأثير العوامل الاقتصادية العالمية الأخرى مثل التضخم وأسعار الفائدة على أداء المحفظة. وأخيراً، كان من الممكن تقديم توصيات أكثر تفصيلاً حول كيفية تطبيق النتائج في الواقع العملي للمستثمرين.

The objective of this research was to create an optimal investment portfolio of all securities listed on the Damascus Stock Exchange based on the historical prices of the listed companies by using the Solver tool in Excel. A simple analytical study w as conducted for Damascus Stock Exchange. Since the beginning of the period studied in 2010 to 2017 significantly, where the increase was observed in 2017 clearly as a result of increased trading and large volumes. Thus, an optimal financial portfolio was formed with a yield of 1.79%, a risk value of 6.17% and a risk pricing of 0.29 and a lower risk than the majority of companies, in addition to ensuring the highest return in the portfolio at the same time less risk. The portfolio consists of 21 securities, including 11 from the banking sector, ie 52.3%, 6 insurance companies, or 27.7%, one industrial company and one service company.

The analytical relationship that gives the neutron beam flux does not take into account the probability of decay. In this research, we concluded the analytical relationship of the probability non decay of free neutron during the passage of the sam ple to be analyzed by NAA. And the conclusion of the analytical relationship to the probability of non-capture of the free neutron during the its passage of the sample to be analyzed by NAA in a simpler method than the previous conclusion. We conducted an application study to investigate the effect of the probability non decay of free neutrons, that flowing through sample, On the flux of transient neutron beam, for neutron beam with various large thickness samples and for different energies of neutrons. The effect of probability of neutron decay on neutron beam flux could not be negligible for all the energies which are bigger than of thermal.
