...Show More Authors

يدور هذا البحث حول خواص البولي ايثيلين (PE) باستخدام اللاكتام مع مركبات أكسيد النانو المعدنية المستخرجة من نبات (القرنفل) وهي براعم زهرة شجرة القرنفل كمثبت وعامل اختزال . حيث يستقر أكسيد النانو ويغطي البوليمر الطبيعي. الهدف من الدراسة هو أن أكسيد النانو يؤدي أفضل ترابط للمركبات المحضرة ، بسبب زيادة مساحة السطح ، وبالتالي القدرة على الارتباط بالبوليمر المحضر. والقدرة على الثبات الإلكتروني بسبب كثرة الروابط مما يسمح بتوزيع الشحنة الإلكترونية ثم تشتيتها خارج سطح البوليمر مما يحسن من خواص البوليمر ويجعله مادة صديقة للبيئة يسهل استخدامها تقنية مرتبطة بالصب. بحيث لا يضر بصحة الإنسان والكائنات الحية الأخرى. خلصت الدراسة إلى أنه تم تحضير جزيئات أكسيد الزنك النانوية من مصادر نباتية طبيعية ذات منتج عالي لاستخدامها كمحفز لتحضير المونومرات المهمة صناعياً ، كما تمت إضافة بوليمر لاكتام في وجود أكسيد الزنك المستخرج من النباتات (القرنفل). بوليمر اصطناعي يتحلل عندما يستهلكه الإنسان. تم تمييز جزيئات الأكسيد النانوية والمونومرات والبوليمرات باستخدام طرق التحليل الطيفي. وأشار تحليل FTIR و TGA وباستعمال حيود الأشعة السينية (XRD) والمسح المجهري الإلكتروني (SEM) والفحص المجهري للقوة الذرية، أن البوليمر الناتج عبارة عن مادة متجانسة ذات وزن جزيئي مرتفع مطعمة بمقاييس نانوية عالية الجودة.

A New Feature-Based Method for Similarity Measurement under the Linux Operating System
...Show More Authors

This paper presents a new algorithm in an important research field which is the semantic word similarity estimation. A new feature-based algorithm is proposed for measuring the word semantic similarity for the Arabic language. It is a highly systematic language where its words exhibit elegant and rigorous logic. The score of sematic similarity between two Arabic words is calculated as a function of their common and total taxonomical features. An Arabic knowledge source is employed for extracting the taxonomical features as a set of all concepts that subsumed the concepts containing the compared words. The previously developed Arabic word benchmark datasets are used for optimizing and evaluating the proposed algorithm. In this paper,

A new Cumulative Damage Model for Fatigue Life Prediction under Shot Peening Treatment
...Show More Authors

 Abstract

In this paper, fatigue damage accumulation were studied using many methods i.e.Corton-Dalon (CD),Corton-Dalon-Marsh(CDM), new non-linear model and experimental method. The prediction of fatigue lifetimes based on the two classical methods, Corton-Dalon (CD)andCorton-Dalon-Marsh (CDM), are uneconomic and non-conservative respectively. However satisfactory predictions were obtained by applying the proposed non-linear model (present model) for medium carbon steel compared with experimental work. Many shortcomings of the two classical methods are related to their inability to take into account the surface treatment effect as shot peening. It is clear that the new model shows that a much better and cons

Standards of creditworthiness of customers and their impact on the liquidity of Iraqi private: Applied research in a sample of Iraqi private commercial banks
...Show More Authors

Customers' creditworthiness standards are the key means employed by private commercial banks in assigning a suitable credit assessment for each customer. Accordingly, it had an instrumental role in indicating the degree of solvency of the potential customer before granting the required credit. The research problem reveals the nature of the relationship between the criteria of customer’s creditworthiness and banking liquidity. The most critical objectives of the study shed light on the role of using creditworthiness criteria as a tool for credit analysis of customers by banks that help reducing credit risks and thus increase banking liquidity. The questionnaire that was distributed to bank employees, the research sample, which w

The study seeks to determine the levels of credit structure (independent variable) depending on its components (loans, credit disseminate, other facilities) To get the eight patterns of the structure of bank credit for the purpose of assessing the relationship between changes in levels of each style of structure credit (increase or decrease) and reflected in maximizing the value of the Bank(The adopted a measured variable depending on the approximate equation of simple Tobin's Q) to determine the style that achieves the highest value of the Bank, to take advantage of it in management, planning and control by knowing the strengths and weaknesses of the historical distribution of the facilities . the sample of the
