المستخلص: The change regards basic character of age or our life, the changeability has been happened as a result of interaction of many drivers, the response was differs to this change from state to anther.The important of nuclear proliferation issue had been raised, especially in the world after the cold war era.The research in history of the development of nuclear proliferation issue. So important, to know what its development? And what's reach of it ?.And also we must to study the international system, international structure and the pattern of power distribution and as a result that phenomenon (nuclear proliferation )regards from most complex of international strategic and politic. In the other hand the important of study rise in present an image to world changing and discover the connection between the nuclear proliferation control and the pattern of power distribution in one hand, and with the international system ,the international structure.The study aimed to achieve many purpose such as : 1 - Try to give an image a bout the global change.2 - Try to know ,what the density of nuclear weapons.3 - What the nuclear proliferation control means ?what its machineries ? and its approach? .4 - What the international system ,the international structure mean? and what's machineries of the changing of it?.5 - How was the international relations in the cold war era ? and how effect by the nuclear proliferation control?.6 - How was the international relations after the cold war era ? and how effect by the nuclear proliferation control?. how the unipolar system effected by the machineries which using to control of the phenomenon ?. 7 - What is the future of the phenomenon?.To achieve these purpose the study depend on many approaches, historical, systematic, analytic, descriptive and futurism approaches. The study distributed on introduction, four sections and abstract. The first section deal with the theoretical and conceptual. While the second section deal with study of the nuclear proliferation and international powers relations in the cold war era. The third section concert by the nuclear proliferation and international powers relations after the cold war era.The fourth section study the scenario of the future of the international structure and the nuclear proliferation control. The thesis had been reached many conclusion we can summarized in the following : 1 - The change is a comprehensive operation on systems function and social relations, and its multilevel and multidimensional. The changeability as outcome don’t happened in the system forma alone but also in functions which system perform it. . 2 - The political changeability describe as general, permanent ,comprehensive ,complex ,infinity and time phenomenon (depend on time as mainly factor in changeability.3 - There are many theories had been explained the change operation, according to that the researchers looked to this operation as circler or linear development.4 - The international system had been passed in physical changes . 5 - The international system will not stable in one forma ,but will take many forms according to objective and selfish of the system ,its development and at systems structure according to structural theory.6 - There are many changes drivers ,the changeability of the international structure, and regard as a outcome of the change drivers push towards acting certain forma for concerning phenomenon. 7 - The changeability in international structure and its form will effect in all aspect of the nuclear proliferation operation, because the strategic and tactics which followed by the active powers in international system will changing according to its position in international structure or international system.8 - The nuclear proliferation basically will take two forms ,horizontal and vertical ,the international law and international agreement prevent the horizontal and regardless about the vertical .9 - There are many approaches to the nuclear proliferation, but the basic types are global and regional approaches ,and there are integrated relation between them.10 - The nuclear proliferation control concept differs from disarmament concept but that will not prevent studying the first concept as a part of the second.11 - There are strong relation between the nuclear abilities and nuclear weapons , but not necessity every state have nuclear abilities will industry and have nuclear weapons .12 - The international system regarded on of the most unstable type among anther of the political systems.13 - In spite of the state stay the main actor in international relations but it not unique actor, many actors become play important role by the nature of international political system.14 - The international political system depend on the interaction relation, any behavior of any actor will effect by the others, so that we will must to study these groups especially the radical groups which have political purpose.15 - There are may form take it by the international premedical such as unipolar, bipolar and multipolar .16 - The distribution of international nuclear power there are declared nuclear powers according to NPT, nuclear state by de facto,and the threshold state.17 - The nuclear proliferation in the cold war era according to international power relation, the ideological conflict and the distribution of power, the military forces played political objective more than military. 18 - The nuclear proliferation machineries passed in many stages , in some time two - party agreement or multiparty agreement 19 - The détente between the US and soviet union push the nuclear nonproliferation before the end of the cold war.20 - After the end of the cold war , the US dominated on the world, theories and vision explain the capitalism victory it began to reread the history to make a new history ,the neorelastic,the end of history and the clash of civilizations, the last warning from the American over - confidence, and to ready to the future.21 - The machineries of the nuclear proliferation control after the cold war according to American domination by the American system such as missile shield project, extend the NPT, and motivation and sanctions system.22 - In spite of the regional approach was not prefer by the USA, it plays important role in American nuclear policy, the connection so closed between the international and regional approaches.23 - After the events of 11 - september 2001 escalate which international terrorism phenomenon which had been changed the world vision to nuclear issue also the concept of the war changed, the preemptive war have been followed.24 - The double standers policy had been followed by USA with its treatment with the nuclear programs.25 - The international satisfaction was born by necessity of the change to control to the spread of nuclear weapons.26 - The international structure may be witness an significant changing, the type of the multi appear, the partnership type it must with American leadership, which reflects to the future of nuclear proliferation phenomenon may take two types : a - The nuclear proliferation out of the control.b - The nuclear proliferation under of the control.27 - We must to ensure the next danger to the humanities life is not in the nuclear proliferation, but in the international, regional nuclear technology, may using in changing world. And local conflict and its developing especially if based on it.

المستخلص: بدات الدعوة الى الاصلاحات الدستورية في الدول العربية منذ التغييرات الكبرى التي حدثت في العالم، خاصة في العقد الاخير من القرن العشرين بعد تفكك الاتحاد السوفيتي والكتلة الاشتراكية، وانهيار نظام القطبية الثنائية بانفراد الولايات المتحدة الامريكية في الساحة الدولية وطرح ما يسمى بالنظام الدولي الجديد، هذه الهيمنة السياسية والاقتصادية دفعت الى تصاعد الدعوات الى الاصلاح الدستوري ضمن اطار شعارات الديمقراطية وحقوق الانسان، وبناء مؤسسات المجتمع المدني وازدادت هذه الدعوات بشكل كبير بعد احداث 11 ايلول 2001 . وفي هذا السياق فقد مثل الاصلاح الدستوري في الدول العربية نوع من الاشكالية من خلال التناقض بين ما هو وطني وما هو عالمي، اذ ان الترابط ما بين مطلب الاصلاح وبين مطلب وضع الدستور وتعديله، هو ترابط تاريخي له ضرورات واقعية، فمن ناحية لا يمكن ضمان واستمرار واستقرار عملية الاصلاح بغير دستور يحميها، ولكن ليس الدستور فقط هو الضامن لعملية الاصلاح، اذ ان الدستور مهما كان صريحا واضحا، الا انه لا يمكن ان يضمن عملية الاصلاح الا اذا توافرت الارادة السياسية للنظام السياسي على البدء فيه او الاستمرار في دعمه وتطويره، فالاصلاح الدستوري هدفه احداث تغييرات ملموسة في بعض او جميع نصوص الدستور تقود في النهاية الى الاصلاح الشامل، اذ لا يمكن ان يتحقق اي اصلاح بدون اصلاح للدستور، ويتم ذلك من خلال وجود دستور يحدد العلاقة بين الحاكم والمحكوم وكيفية تشكيل السلطات العامة، وما مدى صلاحية هذه السلطات وما هي العلاقة بين كل سلطة واخرى، وان يكون هناك نص واضح يبين الحقوق والحريات العامة للمواطنين، واذا كان هناك دستور تجاوزه الواقع، فلا بد ان يتم اصلاح ذلك الدستور لينسجم مع الواقع القائم. وهنا يطرح الاصلاح الدستوري بهدف اصلاح القواعد الدستورية التي تشير عن سيطرة سلطة ما على بقية السلطات، او انتهاك حقوق المواطنين وحرياتهم، او تكريس نظام حكم معين. اما الاليات العملية لاصلاح الدستور فتنص عليها قواعد الدستور، وهي تختلف صعوبة او سهولة بحسب مرونة الدستور او جموده. كذلك فان الدستور هو انعكاس للظروف التي تعيشها الدولة، وعليه فلابد من تعديل نصوصه بما يتماشى مع تلك الظروف، والا حدث انفصام بين النص والواقع. اذ ان كثيرا من الدول العربية تخشى من اثارة فكرة اصلاح الدساتير رغبة في تحقيق وحماية الاستقرار، كما لو كان الاصلاح مهددا او معرقلا للاستقرار، وكيف ان الاصلاح قد يكون مطلوبا من اجل الاستقرار، وان عدم القيام بالاصلاحات الدستورية، او مقاومة متطلبات الاصلاح كثيرا ما كان من اسباب تهديد الاستقرار، وبذلك فقد اصبح الاصلاح الدستوري في الدول العربية هدفا ضاغطا وتحول شيئا فشيئا مع انكشاف ضعف الانظمة الحاكمة في الدول العربية وعجزها عن موازنة الضغوط الخارجية والداخلية، من خلال طرح اشكالية جديدة تتعلق بالعلاقة بين دور الداخل ودور الخارج في تحقيق الاصلاح الدستوري وضمان تقدمه ونجاحه.اهمية الدراسة : يعد الدستور اعلى مؤسسة قانونية في المجتمع، حيث يتضمن قواعد العمل السياسي المشترك ما بين كل قوى المجتمع للانطلاق منها وعبرها الى البرامج المختلفة لتلك القوى في داخل المجتمع عند الوصول الى السلطة، لذلك جاءت اهمية الدستور السياسة في الزام والتزام من في السلطة بتلك القواعد عند الممارسة السياسية. ان اجراء الاصلاحات الدستورية يقود الى ضرورة قبول كل قوى المجتمع بها، والزام الحكام بتطبيقها من خلال اولا الاتفاق على تحديد مجالاتها وثانيا السعي الى تطبيقها لمواكبة التحولات على الصعيدين الداخلي والخارجي.هدف الدراسة : تهدف الدراسة الى تتبع عملية الاصلاح الدستوري في الدول العربية منذ عام1991 - 2007، والمجالات الاكثر حضورا في تلك العملية. اضافة للبحث في مشاريع الاصلاح غير المنجزة ومجالاتها، ومعرفة التاثير السياسي والاقتصادي والاجتماعي لتلك الاصلاحات ومعرفة دوافعها الداخلية ومحدداتها الخارجية.فرضية الدراسة : تقوم الدراسة من اجل بلوغ اهدافها على فرضية اساسية مفادها : ان الاصلاحات الدستورية هي حاجة ملحة لمواكبة التحولات الاجتماعية والاقتصادية والسياسية في اي دولة، وقد تبنت الدول العربية مجموعة اصلاحات دستورية منذ عام1991 الى عام2007، الا ان هذه الاصلاحات ركزت بالدرجة الاولى على متطلبات المجتمع الدولي من جهة ومنح الحكام صلاحيات اوسع من اجل ضمان البقاء في السلطة اطول فترة ممكنة. ومن اجل اثبات ما جاءت به الفرضية، كان لابد من الاجابة عن التساؤلات التالية : 1 - ما هي خصائص الدساتير التي يمكن اجراء الاصلاح عليها؟2 - ما هي التحولات الاجتماعية والاقتصادية والسياسية التي تفرض عملية الاصلاح؟3 - هل للعوامل الخارجية اثر في توجهات الاصلاح الدستوري في الدول العربية؟4 - ما هو دور السلطات الحاكمة في تحديد مجالات الاصلاح الدستوري سواء على الصعيد الاجتماعي - الاقتصادي - السياسي؟5 - هل كان لمطالب المعارضة السياسية دور فاعل في عملية الاصلاح ومجالاته؟6 - هل افرزت هذه الاصلاحات عن نتائج ايجابية، ام بقيت غير مفعلة مبتعدة عن الواقع الاجتماعي - الاقتصادي - السياسي؟ منهجية الدراسة : ان المنهج هو الطريق الذي يودي الى الكشف عن حقيقة معينة، ويكون ذلك عن طريق مجموعة من القواعد والوسائل التي يتبعها الباحث للوصول الى هذه الحقيقة، ولذلك اعتمدت الدراسة من اجل التحقق من صحة الفرضية التي تقوم على منهجين هما : منهج التحليل النظمي الذي يقوم على جمع المعلومات واعتماد المنهج المقارن.اشكالية الدراسة : تبعا لما تقدم ذكره فقد باتت اشكالية الدراسة واقعا عمليا بين السبب وتفاصيله من ناحية الاصول والصياغة اذ تتجسد في تساؤلات عدة تضمنت : - ما هي الفائدة التي عادت على الدول العربية مما يطلق عليه بالاصلاح الدستوري؟ - وهل ما تم من تغيير او تعديل على نصوص الدستور يعد اصلاحا دستوريا حقيقيا؟ - وما هي القوى السياسية التي دفعت باتجاه القيام بتلك الاصلاحات الدستورية؟هيكلية الدراسة : تقوم الدراسة على هيكلية تتكون من مقدمة واربعة فصول وخاتمة وهي كالاتي : - الفصل الاول خصص للاطار النظري والمفاهيمي اذ سيتناول الاصلاح ومجالاته، من خلال ثلاثة مباحث. - الفصل الثاني فقد خصص للبحث في نشات وخصائص الدساتير في الدول العربية، من خلال ثلاثة مباحث . - الفصل الثالث فقد تناول دوافع الاصلاح الدستوري في الدول العربية من خلال مبحثين. - الفصل الرابع تناول الاصلاحات الدستورية ومشاريعها المستقبلية، من خلال مبحثين . | The interest of this study stand on the main changes that happened in the world, exclusively after the soviet union decline and socialist block, and the USA as a unipolar international system. The new world order pushed the states to take the constitutional reformation as one of the main issues, this issue developed after the 11 Sep. events and what were Arab States accused for it. The Constitutional reformation in Arab states occur between what's was democracy and what was nationally. And there was relationship between any reformation and the political will. Many of Arab states afraid to provoke the idea of constitution reformation in order to achieve and protect their stable. Because the Arab political regime saw that any constitutional reformation may threat their presence. Moreover the reformations goals in these states discovered it's weakened. Here, set some questions are : - What are the benefits that belong to Arab states from the constitutional reformation? - is what change to constitution considered as a really constitutional reformation? Study structure includes four units abstract and conclusion as below : - Unit one : aspects and theoretical frame in three chapters, the first : the aspects of reformation, second : reformation sides and its similarity aspects, third chapter : the constitutional reformation and its similarity aspects. - Unit two : the born and characterize of conditions in three chapters, first chapter : the beginning of constitutions born, second : the method of Arab constitutions, third chapter : the Arab states constitutions characteristics. - Unit three : the constitutional reformation in Arab states into two chapters, the first chapter : the legal, political, social and economic internal motivation, The second : political and economic external motivation of constitutional reformation. - Unit four : the constitutional reformation and its future protect into four chapter, first chapter : the political side, the second chapter : the social sides, human rights and public liberty, third chapter : economic sides and the last chapter : the main conditional reformation projects. Ended with abstract, conclusion and recommendations.Study conclusion : 1 - The Arab political regime has not the devise and will enough to act the constitutional reformations because they thought that and reformations threat their presence.2 - The importance of the Arab states constitutional reformation is very necessary because of threats and challenges that occur around them.3 - The constitutional reformations in many Arab states come from the political leadership alone and represented the decision maker vision in every change, after and remove constitutional provisions.4 - Major of constitutional reformation in Arab states occurs with isolation to their people and it seeks to control the power in one side without any participation in their life.5 - It's needed judicial and legislature reformations without any political obstacles that stop it like curfew.

المستخلص: There is no doubt that the study of one of the future phenomenon , is a process of scientific research , starting from the past of the phenomenon , passing by it's present to look for it's future prospect and factor of change in it . The national security adviser to president (Carter) (Zbigniew Brzezinski) mentioned that (Future can and must be planned , without careful choice , change may cause anarchy) . In reference to the need to predict the future and a willingness to deal with it's variables .War , is one of the phenomena that accompanied time in all it's different dimensions , past and present and future . It is very old because it emerged with the emergence of human societies since the dawn of human civilization , and continues to the present day , and will remain to along time , as far as those communities remain . It is part of human nature which can not be changed , and the highest forms of conflict to resolve the contradictions . Reality proved the incorrectness of that point of view which has been spread after the end of the cold war in (1991) and resulted in apoint of view which stated that the phenomenon of the international conflict in general , including the phenomenon of war , will become a phenomenon of the past , or that the future wars will be conventional wars , the human is still in their planetary - level enough to destroy their planet hundreds of times , but that the land no longer satisfy their appetite and military instincts for destruction , and instead it is transmitted to space and stars war .In a world where technological development has become the key to progress , and competition intensified through technology , and which influence will be extended to the political , strategic and economic aspects , and working towards making technology a controlling factor which qualifyes it's adapter to have the control in any other field , the persistence of the war phenomenon makes it's study and understanding , as asperate which has it's rules and laws and governed by it's specific circumstances , and as a field generated and influenced by various political , economical and social fields , a vital issue , not only to the specialists , since that the management of the war and the development of strategies , is no longer the prerogative of the generals , but these strategies draw on the table of tables , rallied around the leaders , generals , technicians , scientists and the educated , even in the most developed countries . we do not mean that the study of war is a study of battles and military campaigns or to identify the types of weapons and others , but also be studied at a higher level which the level of strategy , operations and tactic .From here stems the problem of the study , that the future wars will view dramatic developments turnes concepts and standards known to the military affairs on it's head , as a result of the accumulation of the impact of the diversity and the evolution of multi - output revolutions , like technology , information , media and economy revolution , and other revolutions that have passed automatically to the military arenas . The contribution of the expert systems and equipments of artificial intelligence and neural networks and X - ray laser , as well as the robot and super computer in defining the target and turning it in moments , in addition to the contribution of algorithm schemes and communication equipment , as well as the development of theoretical and applied science in facilitating the full implementation of war training ahead of time , in a way that enhance success factors and causes of failure . Those contributions are important which lead us study this subject through raising main question : - How future wars will be with the development of military technology , and its recruitment in the means and tools of war ?To answer these questions , the study started from a hypothesis referring to that the recruitment of the technological development for military fields with armed forces , will alter the nature of future war , so that they accommodate with the challenges posed by the third wave at the military level . In the context of answering the question mentioned above, more than one method have been adopted , according to the requirements of the study , for example , including a historical approach in the study of campaigns and battles which have had a significant impact in the development of means and tools of war , and the diversity of strategies and tactics . and also a functional approach to search in the functions and contributions of the new fields of technological development . and also the future approach to predict some elements of future wars , with the benefit from the expertise of modern wars in the last decade of the 20th century , and the first decade of the 21 century . In the light of the hypothesis which has been put forward, and in order to demonstrate it , this thesis will be structured into four chapters provided to answer the question raised , in addition to a conclusion . In chapter one , I have had to study the technology and the war as a conceptual framework , the first section dealt with the concept of appealing against the terms of concepts and approach , while the second section dealt with the dialectic relationship between the two terms , and their effect on policy .Chapter two studied technological development and war in the 20th century in two sections . It tackled the development and war until the second world war in the first section . and during the cold war in the second.Chapter three focused on the development of technology and war after the Cold war and it's impact on military affairs , to deal in it's first section the new fields of technological development . In it's second section , it dealt with revolution in military affairs .Finally , the fourth chapter studied the technological development and the wars of the first decade of the 21 century , to deal in its first section the war waged on Iraq on 2003 as a case study . and the future of technological development and war , in its second section . In addition to the conclusion , summarizing the content of the thesis , and it's deductive and recommendations.It should be noted , that the study of the technological revolution and future wars , is not without a number of difficulties , such as : - The confidentiality of information relating to military affairs , in general , and the war strategies and management , specially . - Limitations and the obsolescence of the available information on the subject of study , particularly with regard to the phenomenon of war . the scarcity of information available in the base , and the descriptive nature of the شwars in the depths of history , each with their own conditions , and are leaving room for doubt one of the difficulties in the future research of this phenomenon .In the end , I ask God Almighty to make the pragmatic scientific work that involves service to the nation , the paper finds it's place in our Arabic library .

المستخلص: A theoretical and computational investigation was carried out in the field of laser - plasma interaction using the Finite Difference Method to study the acceleration of electrons with non - relativistic velocities in a non - magnetized and magnetized collisionless plasmas.First, a (Nd : YAG) laser pulse of 25 fs duration and 5x1015 W/cm2 intensity was assumed in the present study.When this laser pulse was allowed to interact with a stationary electron in vacuum, it was found that the electron is accelerated during the interaction only and returns to stationary state after the laser pulse has passed, in agreement with previous works.Also, the interaction of the same laser pulse with a collisionless plasma at electron density ne= 1x1018 cm - 3 was studied. It was noticed that the energy of the electron during the interaction has reached a maximum value of ~ 1 keV at laser pulse intensity of 5x1015 W/cm2, while the energy of the electron after the interaction reached ~ 15 eV for the same laser pulse intensity.Finally, the interaction of the same laser pulse with a plasma was studied at electron density ne=1x1018 cm - 3 in the presence of an external magnetic field for the three values of the field strength B= 60 MG, 70 MG and 80 MG. It was found that there is an increase in the acceleration of the electron to reach a maximum energy of ~ 19 keV at a laser pulse intensity of 5x1015 W/cm2 and an applied external magnetic field strength of 80 MG during the interaction. However, the electron energy after the interaction reached ~ 3 keV at a laser pulse intensity of 5x1015 W/cm2 and an applied external magnetic field strength of 70 MG. This is due to a sustainable generated laser wakefield of ~ 2x109 V/cm. Thus, it is concluded that an applied external magnetic field assists the acceleration of the electron and can subsidize for a high laser beam intensity

المستخلص: The aim of this research is simulate an optical system for the human eye using Genetic algorithm. The considered optical characteristics of the optical system simulator include spot size (Z), spot diagram, and effective focal length (EFL). These characteristics are determined with the aid of some mathematical relations, which give the efficiency and accuracy of the adopted optical system design. The work has been performed in two stages : In the first stage, Genetic Algorithem optimization (GA) is used to get the best design by optimizing the optical featurs of the eye elements. The optimal eye design was tested using Zemax software, the test includes estimation of the image quality, and optimal performance for the proposed optical eye system.The second stage was implementing a specially developed software to simulate the behavior of the human eye. The simulator using visual basic 6 and works under Windows operating system, it is able to plot the eye design graphically, and can estimate the considered optical functions to determine the efficiency of the eye simulator.The simulator showed agood results for spot size, spot diagram and EFL, the present work has been gained some credibility when the considered optical functions achieved by the simulator are found compatible with those achieved by Zemax, since the comparison showed a behavioral matching between them, which ensure the correct path of the GA based eye design and the successful proposed eye design.

المستخلص: This project investigates the detection and evaluation of imperfections in internal structures of castings and welded joints by x - ray radiography. Optimum radiography conditions that lead to clear and high contrast image on the radiograph were studied.Equations derived earlier for finding the size and depth of defects in castings were used in this project to test their applicability to a wide range of geometrical parameters used in radiography.The importance of non - destructive testing NDT in industry is discussed. X - ray radiography being one of the NDT techniques, has some privilege over other techniques. For example, welded joints sometimes contain internal flaw or blowholes that may escape detection by other NDT techniques but can not escape detection by x - rays. Two kinds of samples are prepared for radiography. The first sample is aluminum casting through which two different sizes of steel spheres are included. This sample was radiographed from two opposite sides and the x - ray films were analyzed.The second sample is steel plates which are welded by arc welding and then radiographed by x - rays.Imperfections in this sample such as incomplete root penetration, undercut and porosity were detected by x - ray radiography. Different conditions influencing the preparation and radiography of the above samples were studied. The prepared welded sample was radiographed three times for different high voltages (120,140,160) kV respectively with an exposure time of (80) second. The best quality image where the defects can be detected clearly if its size is (5%) of the radiographed object using (120) kV and (140) kV. Moreover the results show that the optimum film gradient was found at (140)kV and the contrast is better than obtained with (120)kV while darkening image was found at (160)kV.In field of the aluminum casting, the two equations were derived earlier proved their capabilities as a right method for identification each of size and depth of such defects in castings and welded joints

المستخلص: The aim of this study is to detect the radioactivity of radionuclides and measure the specific activities and the uranium concentration in (30) samples of crude oil and oil waste were brought from three oil locations Dora refinery, Bijie refinery, and north field of al - Rumaila. The measurements in this study were done by using two techniques : 1 - Gamma rays spectroscopy system was used to measure the specific activity for radionuclides. This system is consist of high purity of germanium detector (HPGe) with personal computer as multi channel analyzer (MCA) that computerized to plot the radioactive spectrum and compute the specific activities of the radionuclides. There are seven radionuclides are detected : (Bi - 214, Ra - 226, TI - 208, Bi - 212, Pb - 212, K - 40, and Cs - 137), these radionuclides included; two radionuclides (Bi - 214,Ra - 226) belong to the U - 238 series, three radionuclides (TI - 208, Bi - 212, Pb - 212) belong to Th - 232series, one natural radionuclide (K - 40), and one artificial radionuclide (Cs - 137).For Dora refinery samples, the averages of specific activities of (Bi - 214, Ra - 226) were (7.79, 16.08) Bq/kg respectively, the averages of specific activities of (TI - 208, Bi - 212, Pb - 212) were (7.95,4.05,5.75) Bq/kg , the average of specific activities of (Cs - 137) was (0.64) Bq/kg , the average of specific activities of (K - 40) was (99.3) Bq/kg. For Bijie refinery samples, the average of specific activities of (Bi - 214)was (0.39) Bq/kg, the averages specific activities of (Bi - 212, Pb - 212)were (0.02,0.01) Bq/kg, the average of specific activities of (K - 40) was(2.28) Bq/kg , and three radionuclides (Ra - 226, TI - 208, and Cs - 137) werenot appeared in Bijie samples.2 - solid state nuclear track detectors technique (SSNTDs), the uraniumconcentration determined by using CR - 39 track detector and fissionfragment track technique, the nuclear reaction used as source of uraniumfission fragment is U - 235 (n - f) obtained by the bombardment of U - 235with thermal neutrons emitted from (Am - Be) neutron source with flux(5000 n/cm2.s) for seven days, the concentration were calculated bycomparison with the standard samples.The uranium concentration in Dora refinery samples were rangedbetween (0.95 - 3.34) ppm with average (2.03) ppm for solid samples and(1.25) ppm for liquid samples.The uranium concentration in Bijie refinery samples were ranged from(0.42 - 1.46) ppm with average (0.55) ppm in the solid samples and (1.24) ppm in the liquid samples.The uranium concentration in the north field of al - Rumaila samples were ranged between (1.78 - 6.35) ppm with average (3.37) ppm.From above results, we concluded that the maximum of uranium concentration was found in the north field of al - Rumaila in Basrah governorate, these results are agreement with the permissible limit from IAEA. The maximum of external equivalent dose rate from NORM in oil waste was found in the north field of al - Rumaila was (0.30) mSv/y less than the permissible limit from IAEA which is (1) mSv/y for the public.

المستخلص: In this thesis, we consider the extreme value distn. of two parameters for the reason of its appearance in many statistical fields of applications. Mathematical and statistical properties of the distn. such as moments andhigher moments are collected and unified and the properties of reliability and hazard functions of the distn.are illustrated.The chi - square goodness - of - fit is used to test whether the generated samples from the standardized extreme value distn. by Monte Carlo simulation are acceptable for use.These samples are used to estimate the distn.parameters by four methods of estimation, namely moments method, maximum likelihood method, order statistic method and least squares method.These methods are discussed theoretically and assessed practically in estimating the reliability and hazard functions. The properties of the estimator, reliability and hazard functions, such as bias, variance, skewness, kurtosis, and mean square error are tabled.The computer programs are listed in three appendices and the run is made by using "MathCAD 14".

المستخلص: The current study involves preparation number of cysteine derivatives by the reaction of cysteine with different aromatic aldehydes forming the following Schiff bases : "2 - (4 - bromobenzylideneamino) - 3 - mercaptopropanoic acid, 2 - (4 - hydroxybenzylideneamino) - 3 - mercaptopropanoic acid, 2 - (4 - (dimethylamino)benzylideneamino) - 3 - mercaptopropanoic acid and 2 - (4 - chlorobenzylideneamino) - 3 - mercaptopropanoic acid".The new prepared derivatives were identified by using spectroscopy (FTIR) and measuring their melting points.The biological activities against Proteus mirabilis were estimated using well - diffusion method around the plate then the antibacterial activities were estimated.The effects of the prepared compounds on urease activity were studied. The results showed good effect in urease inhibition. All the prepared compounds showed competitive inhibition since the value Vmax was the same and Km increased.Finaly, Vmax, Ki, Km and i % values of the enzyme was calculated using line weaver Bruk equation.It is noticed from enzymatic and biological studies that Schiff bases compounds are strong inhibitors of the urease enzyme where the(2 - (4 - (dimethylamino)benzylideneamino) - - 3mercaptopropanoic acid ) inhibition force was (Ki=0.0043 M) which is the highest inhibition force comparing with the other prepared compounds.The percentage of inhibition (%i) was equal to (96.77%).
