المستخلص: It is very proud for anyone to tackle a great literary work that deals with a brilliant personality with dis - dainful spirit, a hero that history and Kerbala battle witnessed to him, a person that humanity glorified him. All faithfulness is represented by him, dignity refers to him. He sacrifices himself without any care, that is, the hero of Al Taf, Al Abbas Bin Ali ( peace be upon them). The study plan consists of two chapters preceded by an introduction and followed by conclusion. First chapter is entitled ' the phonological level', it hasthree sections : justification, apposition, and assimilation. Second chapter which is entitled ' the morphological level' contained three sections : derivational constructions, infinitiveconstructions, and verbconstructions. The construction has reached the following results : *Al Jude festival poems were built on the same style of the old Arabic one represented by the vertical verse. It has meters and rhyme. They are multipurpose, and at the same time, these poems mention number of merits and virtues of the generous. Al Abbas Bin Ali (peace be upon them) depending on symbol and allegory as a significant artistic device. *Al Jude poets adopted a group of phonological techniques and expressions represented by the overuse ofjustification, apposition, and assimilation, particularlyjustificationwhere all its types used. The same thing happened with apposition where they used the regular and aural. The renewers' opinion walk side by side with Al Jude poets when they adopted its three types that were constructed by the renewers in spite of most traditional thought that assimilation has two and not three types.* Al Jude poets formed most constructions of their poetic texts from the three letter verbs whether what concern forming the present participle, past participle, and the adjective. During their use for these constructions, they were away from original that can be predicted from the context that mentions the derivative construction.

Chapter one deals with intertextuality depending on the poet's religious , historical and social culture by which he expresses his poetry . In chapter two there is an evaluation to the poet's figurative that it is decided by his encyclopaedic cultures. The researcher illustrates that the religious, historical , and social figures should deal with intertextuality because poetry stir emotions and passions. In chapter two, the researcher sheds light on poetic image in which contains many figures of speech ,simile , antithesis , pun taphor and mask . In chapter four concentrates on rhythms which the poet appreciates poetic metres as he beseeches what ancient poets followed. It includes verse metre , internal rhythm and rhyme , which internal contains repetition , antithesis and pun.The modern civilisation in Which emotion have changed, poetry has affected and was affected by classical Arabic, foot poetry , prose poem . Finally the researcher concludes what persudes the readers of her authentic presentation hoping to please them if that happens, it will be by Allah's mercy and blessings if not, definitely it is because of human innate inability Which Allah decided in human being. The researcher has done her best to check up the big number of references she has made use of. May Allah grants success for all

المستخلص: ان دراسة الانا والاخر في شعر وزراء العصر العباسي للمدة من (132_447 هـ) عدة مطلب لا يمكن تحقيقه الا بالنظر الى مكنونات الوزير وخفاياه المرتبطة ببنائه النفسي وتفاعلاته الاجتماعية , ورؤيته للاشياء من خلال منظور قائم على التحليل والاستقراء العلمي لتجربته الادبية . صحيح ان ذلك لا يمثل سابقة جديدة الا ان كل البحوث والدراسات الادبية لابد ان تقترن بمثل هكذا منظور او ان تعتمد على منهج معين في التحليل , بيد ان السابقة الجديدة , تكمن في الوزراء انفسهم , فهم الذين عكسوا باشعارهم صورة الاخر , فكانت اشعارهم نتاج بيئة خاصة اجتمعت فيها جميع المظاهر من الترف والثراء والعلو . وعلى النقيض عانوا في قسم من حياتهم , بؤس وعذاب ومرارة والم اما من سجن او حب او منفى , وانمازت كل حقبة من حقب تجاربهم الشعرية بابداع فني قائم على علاقة جدلية بين الانا والاخر. اذ يكشف لنا (الانا ) عن وجود اخر , فلا يمكن معرفة ماهية الذات الا من خلاله , فهو مراتها , التي نظر من خلالها الى الاخر الانسان والى حركة الزمان , وتحديات المكان , والطبيعة وما بها من الوان , حتى تحولت ذاته الى مملكة من الاحاسيس , والهواجس والمشاعر اتجاه الاخر. اعتمدت خطت البحث تمهيدا وثلاثة فصول وخاتمة , ضمت اهم ما توصل اليها البحث من نتائج.اهتم التمهيد بدراسة الانا والاخر لغويا واصطلاحا , ودراستهما وفق محاور ثلاثة , نفسي , ادبي , اجتماعي . وخصص الفصل الاول بدراسة : الانا التجليات والحضور وكان بمبحثين , واتبعنا الفصل الاول بالثاني الذي اهتم بدراسة : الاتفاق والاختلاف بين الانا والاخر , وضم الاخر الاعلى في المنزلة والاخر الادنى في المنزلة , كمبحث اول واما المبحث الثاني فاختص بالاخر المساوي في المنزلة , اما الفصل الثالث : فكان تحت عنوان , الزمان والمكان الوجوديان اخر, وقد اشتمل على مبحثين الاول ضم : الزمن الوجودي اخر وضم المبحث الثاني المكان الوجودي اخر , كما وضم الطبيعة كاخر مكاني . _ كان النص هو الحكم الاول والاخير في تجلينا للنصوص وما توصلنا اليه من نتائج كانت نتاج عمل تحليلي نفسي لتلك النصوص من اهمها : _ ان الانسان بطبيعة الحال يشعر في اغلب الاحيان بذاته المتعاظمة , وبحسب طبيعة وقدرة كل انسان يتم التعبير عن تلك العظمة في الذات , والوزير كاي انسان دفعته قدرته الادبية ومكانته الاجتماعية عن التعبير عن ذاته المتغطرسة شعرا .الا انه كاي شعر مر بظروف قاسية في حياته جعل منها محطات انكسارات في شعره , عدت من افضل ما قاله الوزير الشاعر العباسي ؛ لكونها نابعة عن عاطفة ووجدان تكاد تكون اكثر صدقا من اي تجربة شعرية اخرى. _ تمثل الاخر عند الوزير العباسي بالحاكم وكانت علاقته به متباينة , فتارة تربطه به علاقة محبة اساسها القرابة او المصلحة, وتارة تراه وزيرا ثائرا على حاكمه ؛ وذلك سببه العلاقات او الخلافات السياسية او الاجتماعية . _ وتمثل الاخر عنده ايضا بالادنى منزلة كالجواري والغلمان الا انهم شكلوا له جزءا من حياتهم ؛ اذ شكلوا اخر توافقي معه ._ كان الدهر والليل والشيب والموت من علامات الزمان المؤثرة سواء سلبا وايجابا على الوزير الشاعر فكان هاجس الغياب عن السلطة يتبعه من خلال الشعور باحد هذه العلامات . كما وشكل المكان اخر بنوعيه الاليف والمعادي والطبيعة كذلك ؛ اذ كان له الاثر الفاعل في رسم ملامح وطبيعة الحياة عند ه .

المستخلص: The alienation is one of the most exciting subjects that most people suffer from. It has attracted the attention of many philosophers and thinkers. It has succeeded in imposing itself on many cultural activities. Alienation is a problem that has taken up a great deal of literary work. Poetry has been a distinctive tool for expressing the suffering and feelings of the expatriate. The modern Iraqi poetic scene is a lot of expatriate colors as a result of the successive political crises that have taken place in this country, namely the confiscation of freedoms, the silencing of mouths, the killing and the displacement of those who have violated it .The experience of Abd al - Ilah al - Yasiri is an important part of the history of Iraq, and it was the duty of the educated person to stand in the face of what was focused on the people of injustice, and raised the Yasiri Brigade of rejection and rebellion against tyrants, this was reflected in his hair from the images expressed the reality of life, It is necessary to highlight this era, because literature is said to be the mirror of life, so it must be studied through the historical stage in which he wrote and interact with it or else it will lose its social value, see the product of Yasiri poetry is clear picture of those who did not witness that period The choice of the subject was not coincidental, but under the guidance of my teacher, Dr. Said Adnan, and I found in myself the great desire to shed light on an important stage in the history of modern Iraq The research consisted of a biography that included the biography of the poet Abdul Ilah al - Yasiri , the beginnings of his poetry, and the most important poetic collections he produced, followed by three chapters complementing each other. The first chapter was the alienation and beginnings and linguistic origin of the word, In the Arabic and Western lesson, and the most important motives that lead to alienation, and was followed by a third topic dealt with alienation in modern Iraqi poetry, and was the course of the talk in the second chapter on alienation in the poetry of Yasiri and colors and what led to it, the rebellion of various purposes, And the artistic image, and the renewal of its elements using the symbol as well as the rhetorical image, the structure of the old poem, and the modern freedom and the style of poetic stories.In conclusion, the main findings of the study were summarized.Finally, my sincere thanks and gratitude to those who contributed to the success of this study, my dearest professor.

المستخلص: Constitute the rotation exponential relationship dimensions positive and negative between the international system over the different stages of the major powers in various manifestations, argumentative and extensive research and one of the main gates of understanding of international relations at the contemporary stage, this relationship has opened ample room for endoscopy and research in but the international system and major powers dramatically, impact, vulnerability and nutrition, nutrition reverse dual between the international system and major powers relationship has alternated according to each stage and this relationship is the main problem of the balance of power in several stages, and when he was urgently needed because of the international system is to be the foundation standard for classification of power arrogance in the world, we became our international system stable and clearly defined in terms of the formation of systemic in different structural dimensions, that the international system is established the concept of structural and quality of states and impose the rhythm of movement for many reasons, notably that the nature of the regime often imposes itself a great obligation for these forces because adopted for fear of imbalance or break up of certain international situation or threat to the status of this or that country. While it is possible that just the opposite is happening as they become the major powers in the zenith of its power is granted international system and give it structure and posed or change the balance, that is, the major powers here are the ruler and the clutch on the decision to change within the system and not vice versa.Of course, and as far as what the major powers and the international system and the issues of restructuring strategy and the required strategic supplies, it became clear manner that does not accept the argument that the concept of power and public and private as has changed helped broadly to re - read the beliefs of the strategic countries in terms of the ups and build self - mechanisms .Importance of the study : Centric importance of the study of it represents an attempt research earnest to form a new theory to explain how they can through the major powers arise strategic detail the destruction, they also offer hypotheses second supplement to the theory of looking at the mechanics of the fading of states and their tracks and provide detailed explanations of the forms of collapse and form, in the sense that the subject of major powers and reshape the international system based on the assumptions of ascent and decline, it represents an attempt to re - read international relations in general and major powers and the international system, in particular in the pot research focuses on the scientific methodology of the measurement, audit and observation and select the tracks.The problem of the study : The study generally runs from the two problems main ways : the first, which is problematic conceptual theory relating to the characterization of and what the big powers and the international system and the nature of the dialectical relationship rotating between the two, the second is problematic current major powers characterization and put it in its proper place according to the hypothesis of ascent and decline and the compatibility of all the power with these hypotheses.The dilemma conceptual first, since the study is trying through, and over the detective and three chapters, the first - the first, second and third - explain what the clash incident between the international system and major powers, as it is trying to study here and across this part of the dilemma that the disintegration of the complex Association about the presence of overlapping relationship is a clear path between the evolution of the international system on the one hand and major powers on the other hand, due to the complexity of the actors and their diversity and change the concept of power and its vocabulary, this relationship appears frequently as a rotational (ie, when they vibrate and weaken the international system, is restored and fed through strategic reaction of major powers on the form of finding a new strategic balance or maintain the strategic balance as and when it weakens the major powers, the system modifying itself in line with the size of the weakness incident to correspond to the requirements and elements of modernization that has occurred in the international environment and gives the stream additional to those strengths that have benefited from the decline in single actors function or polar strategic act also shall be either by maintaining a balance or modify it identifies with the size and manage change).While Applied dilemma second focuses on practical models of major powers and try to determine its position in the international system based on key assumptions that have been developed and adopted a basic criteria for the rise of the big powers and the eclipse, as it dealt with the last three chapters (IV, V and VI) the issue of the status of all power in the international system - models selected - based on the extent of approaching and distancing itself from the hypotheses that have been put forward both in terms of climb or, moreover study focuses in this part of the dilemma defines the shape of the future of the international order based on the data and the reality of the big powers. It is through this dilemma offers a number of central research questions that the study will try to answer them through the next research context, the most important of these questions are : 1. What is the fundamental nature of the relationship between the international system and major powers?2. How can identify the key ingredients that require their presence in the power of any wish to become a major international scope of the system?3. What are the main forms of balance known to international relations throughout history, the nation - state?4. Who are the actors function capable of control in the international system and restructuring?5. How can identify the entrances of change within the international system and who knows this change?6. What is the most important hypotheses that can be through to become a major force on the international scope of the system?7. How can identify the most important hypotheses decline that lead them to collapse?8. Do not slip United States a world power?9. Is Russia today is on its way toward building the same to you mean by itself as one of the poles of the future world again?10. Is China really able to replace the United States? And how?11. What is Japan's new site in the international system?12. What is the future of the international system in the light of data the rise and fall of great powers?Hypothesis of the study : Consistent with the dilemma that have been submitted and research questions that have been submitted and as well as the main hypotheses that have been adopted by the study systematically through the third quarter in an attempt to form a comprehensive theory, the study starts from the assumption president of that on the basis of (that there is a direct correlation "positive + negative" between the regime the one hand and major powers on the other hand. The more major powers more coherent and stronger the more you process the formation of the international system more discipline, and vice versa, the more the international system more solid whenever the major powers to maintain more balance and less likely to change. And branching out from this hypothesis President, two assumptions in two basic subgroups : The first hypothesis : Whenever any major international force backed away from its position, as it was an opportunity to push a new force to fill the vacuum, and this is a dialectical ascent and decline.The second hypothesis : Whenever a major international force backed away from its position as it was an opportunity to reshape the international system according to the new balance of power. This is the dialectical relationship between the international system and major powers.Curricula : The study used the six - round main chapters range of approaches that are used in scientific research on the scope of political science were as follows : 1. The historical approach, which sought the study through used to display the most prominent of the relevant idea of historical experiences and the subject that the researcher wants to clarify, this has been the approach one of the main approaches that have been through it to identify the mechanisms of the fading of the major powers and the conclusion of which many hypotheses have been one of the most important pillars of the study at various stages.2. Analytical Approach : The study used the analytical approach to the study of various plants for several purposes, the most important cases of the dismantling and re - installed in accordance with the main theme of her service, and the support of the conclusions of this approach is based on the basis of scrutiny of reality and studied extensively studied through strategic insight.3. Approach the international system Analysis : It is one of the most major and modern approaches that study sought to focus on it through international structural analysis and situations experienced by the international system and the dismantling of his limbs and its impact, the study was able bumpy this approach to reach many conclusions based on what provided by this approach of the mechanics to understand the phenomenon and absorbed significantly.4. Approach to measure the strength of nations : one of the most important approaches and, most recently that for its research tools have enabled the study to identify the most prominent features of the strength and the weakness of the major powers and greatly helped to explain many of the phenomena and dismantled as it should.5. Future Approach : It is one of the most important methods you used for the purposes of study, the most important of several identifying features scenes of the future of the international system according to the scene forward - looking unconditional. Structural study : As well as the introduction to the study and details and the conclusion and findings, the study contained two doors presidents by six central chapters, the first section by three chapters titled (conceptual framework and theoretical), while Part II came with three other chapters supplement entitled (Applied and future frame).Ensure that the first chapter of the study, which came under the title (the major powers and the international system), the two main two sections (Section I : what the major powers and the international system) while the second part, titled (forms of power in the international system balance).On the other hand Chapter II of the study, which was titled contained (actors in international relations and the entrances to change) on two sections two main (Section I : actors function traditional and new actors function of non - State actors in international relations), while the second section under the title (the entrances to the change in the system international).Also a third chapter of the study, which was titled (hypotheses rise and fall of great powers) of the two main two sections (Section I : hypotheses rise of major powers) while the second part, titled (hypotheses fading major powers).Chapter IV of the study contains two sections and two presidents, who came under the title (the major powers "core" and measuring hypotheses ascent and decline), was the first topic title (the United States) while the second section title (Russian Federation).On the other hand, Chapter V of the study complements the above by two sections presidents under the title of president of the chapter came a (major powers "emerging" and measuring hypotheses ascent and decline), was the first section of the chapter entitled (China), while the second part, titled (Japan) .

المستخلص: There are many important problems where the real data does not fit any of the classical or standard probability models, and the lifetime distributions have been used to model analyses the lifetime data in many applied sciences such as medicine, engineering, finance, biostatistics , reliability and survival analyses because a statistical analysis depends heavily on the assumed probability model or distributions.The distributions, generalization distributions there were derived in this thesis that can be used in life applications. It is hoped that findings of this work will be useful for the practitioners in various fields of theoretical and applied sciences. This thesis is our contribution in this field throughout finding these distributions .Three distributions are introduced, Rayleigh - Pareto distribution, Rayleigh - Lomax distribution and Uniform - Lomax Distribution, as well as discussion of some their important properties , and estimate their parameters. These distributions depend on the original distribution, Rayleigh distribution, Pareto distribution, Lomax(Pareto II) distribution, and Uniform distribution. The idea of the subject that is companied two distributions by one of the methods that are used to generalize distribution.Therefore there is an application using certain real data set to illustrate the usefulness of the proposed distribution to real data using MATLAB (R2011b) software.In the application of Rayleigh - Pareto distribution, we used real data set ,and make a compare between Rayleigh - Pareto distribution used in thesis with others distributions. Its appear that Rayleigh - Pareto distribution is the best in comparison with other distributions.Introduction The statistical distributions used to describe and interpret the phenomena, there are continuous motivations for developing these distributions to become more flexible or more fitting for specific real data sets. Because there are many important problems where the real data does not fit any of the classical or standard probability models.&#34;The lifetime distributions have been used to model analysis the lifetime data in many applied sciences such as medicine, engineering, finance, biostatistics , reliability and survival analysis because a statistical analysis depends heavily on the assumed probability model or distributions.&#34;So the aim of the thesis is to derive some distributions, generalization of distributions ,with of their properties, and estimating the parameters. One generalized distribution F(x) was defined as follows F(x)=I_G(x) (a,b)=(∫_0^G(x)▒〖w^(a - 1) (1 - w)^(b - 1) 〗 dw)/B(a,b) , 00 ,b

المستخلص: Fractal image coding based on the inverse problem of an iterated function system plays an essential role in several areas of computer graphics and in many other interesting applications. Despite this method have received much attention because of its high resolution and fast decoding and many other advantages, but it has not been used widely because, it required high computation time in the encoding process. Genetic algorithm as an efficient optimization approach is highly used to solve such problems. In this study, this technique is improved and implemented, and another improvement that helps to optimize the search space in the target image is proposed, this is through reaching of global optimum in a single run. It is known as crowding method. The first use of this method in solving of fractal inverse problem shows acceptable result, especially, in reducing of the encoding time and obtaining of good quality images. Although, crowding method provides a satisfactory results in comparing to the original Jacquin and genetic algorithm techniques, but it concentrates on the best elements in the population of the search space. To support global exploration and prevent trapping in local optima, a new probability is added, which helps to satisfy diversity in the population selection from both the best and worst individuals. This is satisfied through proposing of a new diversity method to reduce being trapped in local optima, and improve the time complexity of the algorithm. The relation between searching for an optimum solution and playing music is known as harmony search algorithm (HAS). This algorithm is used in this study for the first time to solve fractal inverse problem. It has been proved that access to find music harmony corresponds to solving of an optimization problem searching for an optimal solution. In comparing to the original technique, the experiments on the three proposed approaches show their efficiency and effectivity In this study, a new method that combines fractal dimension (FD) which is an indicator of image complexity with the FIC scheme is proposed. Classifying images in databases according to their texture by using FD helps reduce the retrieval time of query images. The validity of the proposed method is evaluated using geosciences images. Result shows that the method is computationally attractive.

Contained fundamental concepts of topological spaces and rough set theory and also, we introduced the concepts of graph theory. We introduced concepts concerning with topological structures, which is M - space by using the mixed degree systems in graph theory. In addition, the m - derived (respectively, m - open, m - closed) digraphs, m - interior (resp. m - closure) operator and M - subspace are studied. On the other hand, we studied supra - approximation spaces using mixed degree systems, two topological spaces are introduced, namely o - space and i - space. We introduced and compare between the two new approximation operators using mixed degree systems, we find the accuracy of the second new approximation operator is more than the first new approximation operator. For this reason we study in detail the properties of the second new approximation operator.Finally, we introduced a new generalization of rough set theory using a finite number of digraphs by using the second new approximation operator. Several characterizations and properties of these concepts are studied

المستخلص: The Maxwell distribution is a probability distribution with application in physics and chemistry. The most frequent application is in the field of statistical mechanics. Hence, the importance of this study to find best estimators for scale parameter of the Maxwell distribution when there is unknown and so to obtain through Classical estimators(Maximumlikelihood estimators, Uniformly minimum variance unbiased estimator, and Minimum mean squared error estimator), as well as Bayesian estimators using different loss functions represented by Quadratic loss function, Precautionary loss function and Generalized Weighted loss function. And in order to get a better understanding of our Bayesian analysis, we consider the non - informative prior for the scale parameter ( ) using Jefferys prior information as well as informative priors represented by Gumbel Type II prior, nverted Gamma prior and Inverted Levy prior.All these estimators are compared empirically using Mont - Carlo simulation by employing the mean squared errors (MSE's). After that, we derived the better Minimax estimators of the scale parameter for the Maxwell distribution for all loss functions referredabove and reach to the estimators by using Quadratic loss function, and the special case of Generalized Weighted loss function, are Minimax estimators, as for Precautionary loss function is not minimax estimator.Among conclusions that have been reached, The performance of Bayes estimates using generalized weighted loss function based on Inverted Gamma prior information(GWIG03) when(k=0, c=3), is better than the performance of corresponding estimate based on Jefferys prior noninformation, Gumbel type II prior information, and Inverted Levy prior information in most cases.

المستخلص: Analytic Number Theory is regarded as one of the main subjects in the core of the pure mathematics. Specifically, in the Analytic Number Theory, the generalized primes and generalized integers have been investigated and formally defined in 1937 by Beurling . Beurling state that for any real sequence 〖〖{p_i}〗_ 〗_(i=1)^∞ increasing with p_1 > 1 as p_i ⟶ ∞ as i ⟶ ∞ called a Beurling primes or generalized primes. That is, p_i called generalized primes (or Beurling primes) with the fact of the fundamental theorem of arithmetic (each n = ∏_(i=1)^k▒〖p_i^(a_i )〗^ where ai ϵ N0 (= N ∪{ 0 }) forming the generalized integers . In this thesis , we investigate the Beurling prime systems and introduce example which studied firstly by the Italian author Balanzario and addressed the modification of its method.Moreover, we study the connection between the counting function of Beurling integers N_P(x) and the Beurling zeta function ζ_P(s) with a concrete examples.

These results are included in four pivots. For the first time are dealt with this kind of scheme for the general quasi multi - valued mappings to prove new results in approximating fixed point theory. Other results have been dealing with multi - valued mappings, such as, general like - contraction, nonexpansive, Lipschitz k - strictly pseudo contraction, k - strictly pseudo contraction and monotone. The modification of s - iteration, which is called s_(prox.) - iteration, have been studied to obtain results about weak convergence for k - strictly pseudo - contractive multi - valued mappings and strong convergence for L - Lipschitz pseudo - contractive multi - valued mappings, quasi - contractive multi - valued mappings and generalized nonexpansive multi - valued mappings. Some comparisons have been studied which are the equivalence between s - iteration, Picard - Mann, 2step - Mann iteration and Ishikawa iterations schemes. s - iteration is faster than others unless Ishikawa iteration. Another equivalence results is studies between s_(prox.) - iteration and Picard - Mann. Here, s - iteration method can be used to solve delay differential equations and solve a system of two multi - valued ϕ - accretive mappings with retarded argument. In addition to the above a data dependence result is proven for fixed point, convergence results for integral contraction are deduced and many equivalence cases are appointed for single - valued mappings.

Therefore, the main objective of this research is to obtain and compare the performance of some Bayesian and non - Bayesian estimators of the scale parameter, θ, and reliability function R(t) of the inverse Rayleigh distribution. The Bayes estimation has been obtained under five different loss functions (Squared error, Generalized squared error, Modified squared error, Precautionary and Degroot loss function) based on informative prior using Gamma prior and non - informative prior represented by Jeffery prior.

A subsemimodule K of M is said to be stable if f(K) K for each homomorphism f : K → M. A semimodule M is called fully stable if each subsemimodule K of M is stable. The concept of fully stable R - semimodule is converted from the fully stable R - module. In this work, the concept of stable subsemimodule and fully stable semimodule will be introduced and studied, investigating the conditions that will be needed to get properties and characterizations similar or related to the case in modules. Moreover, we will discuss the cancellation property for uniform fully stable semimodules, but first the full stability of the direct sum of fully stable semimodules under certain conditions to be fully stable is discussed. Also, the relationship between full stability of the semimodule and the Baer criterion is studied. Furthermore, the concept of pseudo - stable subsemimodules and fully pseudo - stable semimodules as a generalizations of the concepts of a stable subsemimodule and a fully stable semimodule respectively are studied. Some properties and characterizations of fully pseudo - stable semimodules are obtained
