CORE TECHNOLOGY 2nd YEAR MECHANICAL ENGINEERING
(Faculté des sciences et de la technologie UNIV-BBA, 2025-06) DJENDEL MOUKHTAR
This handout, intended for students in the 2nd year of the common core of technology, aims to:
- Provide multidisciplinary knowledge using different types of materials; metals and their alloys,
ceramics, polymers and composites;
- Allow the student to become familiar with the different shaping techniques (with and without
material removal) of materials used in cutting-edge industrial fields (mechanics, aerospace, naval
aviation, steel industry, medical, etc.).
The approach of this module is based on the relationships between the structure, microstructure,
development, usage properties and manufacturing processes of these materials in the industrial field. It
relates the types of bonds and the different levels of structuring of the material with the mechanical
properties.
Surface Treatments
(Faculté des sciences et de la technologie UNIV-BBA, 2025-01-16) BOUBAAYA Rabah
Surface treatments and coatings currently constitute one of the essential means of improving the functional properties of metals, in particular resistance to oxidation and corrosion, resistance to fatigue in all its forms (mechanical fatigue, thermal fatigue, surface fatigue), thermal insulation, electrical conductivity, resistance to friction and wear, without forgetting the color and appearance, biocompatibility or adhesion of another class of materials (ceramic or polymer). In 2017, they represented between 8 and 9% of the overall turnover of industrial metalworking subcontracting and up to 15% if we include their share in integrated workshops.
Among the different surface treatment processes, it is possible to distinguish four families: structural transformation treatments of mechanical or thermal origin, diffusion or thermochemical treatments, conversion treatments and coatings. The main sectors of activity are automobiles, construction, public works, mechanics, aeronautics and space, weapons, electrical equipment and biomedical.
This handout entitled “surface treatments” is intended for first-year Masters in Materials Engineering students. The aim of this handout is to describe the different surface treatments and coatings based on improved functional properties based on numerous industrial examples. The improvement of these properties is directly a function of the internal health of the deposits or surface layers modified by the treatment. The document will address in a final chapter the different means of destructive and non-destructive control.
It is written in a simplified manner with examples introduced after having given concepts so that the student can assimilate the course content and have a clear vision of its application in the industrial sector.

MECHANICHAL MANUFACTURING
(Faculté des sciences et de la technologie UNIV-BBA, 2025-01-12) BOUBAAYA Rabah
Machining by material removal is one of the processes of mechanical manufacturing. This machining represents the search for solutions that allow obtaining a conceivable part at a cost with good performance, by combining information relating to the chronological order of the operations performed, the use of skilled labor, machine tools, tools and equipment requested. This technique also allows us to produce parts with complex shapes and high precision without modifying the characteristics of the machined material. Material removal machining allows for very precise tolerances, which is crucial in many fields, such as aerospace, automotive and tool manufacturing. This process is applicable to a wide range of materials, including metals, plastics, composites and ceramics, making it a versatile technique for many industries. In addition, this method is also used for the repair or refurbishment of damaged or worn parts, thus extending their service life and avoiding the waste of valuable resources. In summary, material removal machining remains an indispensable pillar in modern manufacturing, combining precision, versatility and cost efficiency. This handout entitled "Mechanical Manufacturing" is intended for second-year students of the Academic License in Mechanical Engineering, Mechanical Construction option. It is designed to highlight knowledge of product manufacturing techniques, in particular mechanical products. It is written in a simplified manner with examples introduced after giving notions so that the student can assimilate the content of the course and have a clear vision of its application in the industrial sector.
This document is divided into two parts, the first part of which concerns the theory of metal cutting from the point of view of cutting materials, geometry of cutting tools, chip formation mechanism, cutting forces, heating and damage of cutting tools as well as the methodology for choosing cutting parameters.
The second part deals with machine tool technology, based on cutting movements, main components and kinematic chains for some machine tools.
رخصة البناء في مجال التعمير وفق القانون الجزائري
(مكتبة كلية الحقوق و العلوم السياسية جامعة محمد البشير الابراهيمي برج بوعريريج, 2026-04-15) خليف صلاح الدين; حرشاو محمد
رخصة البناء هي وثيقة رسمية تصدرها السلطات المختصة، وتسمح ببناء أو تعديل المباني والمنشآت. يهدف نظام رخصة البناء إلى ضمان مطابقة البناء للقوانين واللوائح المعمول بها، وحماية الأرواح والممتلكات، وتنظيم استخدام الأراضي. في الجزائر، نظم المشرع الجزائري عملية منح رخصة البناء من خلال فرض شروط معينة على صاحب الرخصة، وتقديم وثائق معينة مثل الملف الإداري والملف التقني وتأشيرة المهندس المعماري.

رخصة البناء، التشريع الجزائري، البناء، التعمير، الرقابة العمرانية.
Summary
A building permit is an official document issued by the competentauthorities, allowing the construction or modification of buildings and facilities. The building permit system aims to ensurecompliancewithlaws and regulations, protectlives and property, and regulate land use, In Algeria, the Algerian legislator has organized the process of granting building permits by imposing certain conditions on the permit holder and submittingspecific documents such as the administrative file, technical file, and architect'sapproval.

النظام القانوني للإستثمار في ظل القانون 22-18
(مكتبة كلية الحقوق و العلوم السياسية جامعة محمد البشير الابراهيمي برج بوعريريج, 2026-04-15) قاسي الفازية; دحامنة ليندة
لقد سعى المشرع الجزائري من خلال القانون 22-18 إلى تحسين مناخ الاستثمار باستحداث نظام قانوني في المجال الاقتصادي فعمل على تطوير و تعديل القوانين التي لها علاقة بالاستثمار، ومنه جاء القانون 22_18 الذي كرس مبادئ تهدف إلى المساهمة في جذب المستثمرين و لاسيما منهم الأجانب، كما استحدث عدة أجهزة وهي المجلس الوطني للاستثمار و الوكالة الجزائرية لترقية الاستثمار واستحدث منصة رقمية موجهة للمستثمرين،كما عزز مجموعة من ضمانات جديدة كضمان الاستقرار التشريعي و حماية الملكية الفكرية و الإعفاء من إجراءات التجارة الخارجية و التوطين البنكي، إضافة إلى طرق ودية لفض النزاعات ألا وهي الوساطة و التحكيم، كما وسع من الأنظمة التحفيزية التي تسعى إلى استقطاب الاستثمارات الوطنية و الأجنبية من شأنها تحقيق تنمية اقتصادية فعالة من خلال المشاريع الاستثمارية في مختلف القطاعات.

Abstract:
The Algerian legislator sought, through Law 22-18, to improve the investment climate by creating a legal system in the economic field. He worked to develop and amend the laws related to investment, and from this came Law 22_18, which established principles aimed at contributing to attracting investors, especially foreign ones. He also created several bodies, namely the National Investment Council and the Algerian Agency for Investment Promotion, and created a digital platform directed at investors,It also strengthened a set of new guarantees, such as ensuring legislative stability, protecting intellectual property, exempting foreign trade procedures, and banking domiciliation, in addition to amicable methods for resolving disputes, namely mediation and arbitration. It also expanded incentive systems that seek to attract national and foreign investments, which will achieve effective economic development through investment projects in various sectors.
