التوجه الجيوبولتيكي النقدي في العلاقات الدولية : دراسة في المفاهيم و المتغيرات الجديدة
(2023) بن مساهل آلاء الرحمان
Depuis la fin de la guerre froide, le domaine des relations internationales a connu de grands bouleversements dus à l’absence d’un groupe de fondations qui contrôlait autrefois l’analyse des affaires internationales, et il n’a plus la capacité explicative et analytique de comprendre et cadrer la réalité de la scène internationale actuelle, caractérisée par une extrême ambiguïté et complexité. Par conséquent, tout effort de recherche visant à l’encadrer et à contrôler son contenu est très difficile et se heurte à plusieurs obstacles allant de l’obstacle cognitif à l’obstacle politique. Cette étude cherche à examiner le rôle théorique de la géopolitique critique dans le domaine des relations internationales, en remettant en question les manières d'écrire l'espace mondial, en repensant la politique des métaphores spatiales et la manière de construire des lieux, des frontières et de définir des identités dans les pratiques de politique étrangère. dans le cadre du rapport savoir/pouvoir. incarnée dans les pratiques rhétoriques nationales et étrangères. Il vise également à réaliser la carte conceptuelle des pratiques géopolitiques dans le système des oppositions binaires : savoir/pouvoir, ego/autre, sécurité/menace, vérité/imagination…etc. ; Considérant que les pays ne sont pas un lieu sur la carte, mais plutôt une entité logique et organisée basée sur des imaginations et des perceptions géopolitiques.
Le champ de la géopolitique critique a été rapidement redéfini en s’engageant dans le « tournant matériel/non-représentatif » et les nouvelles variables qu’il pose en tant que corps, objets et contextes qui composent le paysage géopolitique. D’une autre manière, l’avenir de la géopolitique critique consiste à affronter les manifestations matérielles des crises ontologiques auxquelles le monde est confronté.
Representation of the solutions of Diophantine equations containing arithmetic functions
(2024-04-18) ZAHRA AMROUNE
The main aim of this thesis is to find solutions and properties to some
Diophantine equations containing arithmetic functions.
To this end, several equations of this form have been studied, among those
containing finite solutions, all have been found, and among those containing
infinite solutions, a part has been represented and proved infinite.

التي تحوي دوال حسابية . لذلك تم دراسة عدة معادلات من هذا الشكل م نها التي هي ذات
حلول منتهية تم إيجادها كلها ومنها الغير منتهية تم تمثيل جزء منها وإثبات أنها غير
منتهية.
تحضري ودراسة خصائص مركبات المواد ذات أساس بنتونيت/بوليمر اكريليك

The thesis addresses the topic of “Elaboration and study of the properties of
bentonite/acrylic polymer based material composites” based on tripropylene glycol
diacrylate (TPGDA) and bentonite.
In this research, we conducted three studies. The interest was initially in studying the
kinetics and mechanisms of phase transformations of local raw bentonite from Maghnia
(Algeria), after the calcination process at different temperatures, and as a result, the
physicochemical properties were studied using (XRD) and (FTIR) devices. (SEM) of the
calcined samples, then the material was examined by differential thermal analysis (DTA)
at different heating rates (10- 50°C/min). Through the examination, we experimentally
calculated the activation energy for the dehydroxylation reaction stage. With the help of
the theoretical aspect, when it was treated in two different ways, the first by holding the
temperature constant, and the second by changing it at different heating speeds, and after
the calcination process at 200 and 700 °C for the bentonite, the X-ray diffraction data
showed a decrease in the value of the separation distance (d001), which expresses the
montmorillonite phase, from 12.72. Å at room temperature to about 11.98 Å and 9.93 Å
and then disappearing after calcination at 800°C. The values of the average activation
energies determined by the Kissinger method are 221.046 kJ/mol and the Ligero method
are 233.076 kJ/mol.
As for the second study, the cross-linked nanocomposite was prepared from tripropylene
glycol diacrylate (TPGDA) and montmorillonite (pure local bentonite), where cation
exchange of montmorillonite was performed using potassium chloride (KCl), sodium
chloride (NaCl), and lithium chloride (LiCl). As a source of K+, Na+, and Li+ cations,
respectively, the physicochemical properties of the prepared samples were then studied
using (XRD), (FTIR), (SEM), and (TGA) devices, which demonstrated the success of
intercalation of TPGDA monomers and their crosslinking within the montmorillonite layers
to obtain On the Cross-linked(TPGDA)/MMtMag-M+ nanocomposite, based on the DTG
curve, we calculated the activation energy and kinetic parameters in the TPGDA
decomposition stage for each sample using the Coats–Redfern model.
As for the third study, we studied the electrical insulation properties of the
nanocomposite Cross-linked (TPGDA)/MMtWy-Cs+ over a frequency range from 12 to 200
MHz and in a temperature range from 293 to 373 K, where we relied on Wyming
montmorillonite as a reinforcement material for this compound. The results showed that
adding TPGDA to MMtWy-Cs+ resulted in improved AC conductivity, dielectric constant,
and angular loss (tanδ) compared to pure MMtWy.
الشراكة المحلية كآلية لتحقيق التنمية المحلية الراشدة على ضوء قانون البلدية 11_10
(جامعة المسيلة, 2024) صغريي يونس - يسعد رابح
The concept of local partnership in achieving local development
emphasizes cooperation between different local entities to plan and
implement development programs. This partnership aims to provide
better services to citizens through sharing responsibilities and utilizing
resources. It is rooted in the idea that active local entities are in a better
position to understand and address challenges in their communities.
Within the context of local law, these partnerships are often given an
institutional character to ensure that local governance is participatory,
comprehensive, and responsive to the community's needs. The law may
define the framework of these partnerships to clarify and detail the roles
and responsibilities of each party, providing guiding principles for
cooperation and coordination.
The ultimate goal of local partnerships under local law is to enhance
sustainable local development that benefits everyone, ensuring that
development initiatives are based on local realities and receive support
and participation from all local actors and stakeholders. This approach is
also seen as a means to strengthen governance.
Therefore, the Algerian government has embraced the concept of local
partnership as a mechanism for achieving local development and
establishing the foundations of good governance. This has led the
Algerian legislator to issue Law No. 11/10 concerning municipalities.
Furthermore, this study aims to highlight the role of local partners
(private sector, civil society, local media) as a mechanism for achieving
local development in light of Municipal Law 11/10.
دور التدريب في تنمية الموارد البشرية - دراسة حالة بلدية المسيلة
(جامعة المسيلة, 2024) أحلام بركاتي - . خالد صبرينة قراس
The aim of the present study is to identify the role of training in human
resources development. In chapter I, we examined the theoretical framework by
identifying the concept of training, its importance, its types and methods, and
finally the obstacles to training. In the second study, we discussed: What is
human resources development through its definition, objectives, dimensions
and finally modern entry points in human resources development and
challenges In the third study, we also discussed the relationship of training to
human resources development through its relationship with both recruitment
and selection of the staff member and then with human resources planning as
well as its relationship to performance survival, improvement and, finally,
compensation and payment, The second chapter was a case study where the
study was applied to the municipality of M’sila by analysing financial data and
available information on training and its role in the development of the
municipality's human resource, Let's conclude that the institution in question
adopts the training process and that there is motivation for the worker in the
institution in question. in addition to the cognitive and professional capabilities
of the worker in question.
