Etude de l’influence des modes de séchage sur la composition chimique et l’activité biologique certaines plantes médicinales locales.
(university of ghardaia, 2025) DJANI Fatna; NADJEM Imane
Cette étude vise à évaluer l’effet de différentes méthodes de séchage solaire sur la composition
chimique en termes de rendement, de concentration en composés actifs et sur l’activité
biologique d’une plante médicinale locale de la région de Ghardaïa (Algérie) la sauge (Salvia
officinalis). Cinq méthodes de séchage solaire ont été comparées : séchage solaire à l’air libre,
séchage solaire sans stockage direct et indirect, et séchage dans un séchoir solaire en argile
(direct et indirect) sur les constituants chimiques (polyphénols, flavonoïdes, tanins et huiles
essentielles) de la sauge. Afin d’optimiser les conditions de séchage solaire qui permet de
préserver la qualité et les composés bioactifs de cette plante.
Les résultats ont montré que le séchage indirect, en particulier avec des séchoirs solaires en
argile, préserve mieux les composés actifs et améliore l’activité biologique. Ces résultats
confirment l’importance du choix d’une technique de séchage appropriée pour valoriser les
plantes médicinales locales.
Course Handout Algorithms and Data Structures
(university of ghardaia, 2026) BELLAOUAR Slimane
A widely held, yet mistaken, belief in public, industrial, and even academic circles
is that a computer is a machine capable of solving problems because it is endowed
with a certain intelligence. In reality, this machine is capable of nothing unless an
entity (for example, a programmer) has shown it the steps to follow, without any
belief that this machine can provide the slightest interpretation of these steps. In
other words, the machine blindly executes the steps. This philosophy of showing
the machine the steps to follow to solve a problem is called an algorithm.
A survey of graduates from Stanford University asked which courses they relied
on most in their professional careers. The introduction to programming module took
first place, followed closely by core software courses covering basic data structures
and algorithms.
In light of this, this course handout, Algorithms and Data Structures: Part 1, is tailored for first-year undergraduate students in Computer Science and Mathematics.
As of the 2025–2026 academic year, it fully complies with the most recent official
ministry curriculum for the Computer Systems (Systèmes Informatiques) specialization. Furthermore, it serves as an excellent foundational resource for other technical disciplines and institutions teaching introductory programming and algorithm
modules.
Additionally, in strict alignment with the strategic policy of the Ministry of Higher
Education and Scientific Research, this course manual is presented in English. This
initiative promotes the widespread use of English in higher education and research,
ensuring our students are well-equipped to integrate seamlessly into the global academic and professional landscape.
While algorithm textbooks are abundant in the literature, they can often be daunting or overly theoretical for novice students. Our objective is to provide learners
with a manual that is accessible, practical, and easy to comprehend, both conceptually and technically. To achieve this:
• We draw upon all our experience acquired over more than seventeen years of eaching algorithms at the University of Ghardaia and other institutions.
• We accompany the explanation of new concepts and new techniques with examples and illustrations.
• Each chapter is followed by a certain number of exercises of varying degrees
of difficulty, well-designed to implement the theoretical knowledge acquired.
These exercises aim to cover professional life situations (mathematical calculations, management, . . . ).
For the algorithmic formalism, we mainly used the conventions of the Pascal language. This formalism makes it easier for students to implement algorithms in a
high-level language. In order to implement the algorithmic solutions, in this handout, we have chosen to use two programming languages: C and Pascal. The C language is chosen because it is prescribed in the official ministry curriculum. The
Pascal language was chosen for its pedagogical value in helping students master
fundamental programming concepts.
To be in line with the official ministry curricula, this book is the first part of a
series of three parts that cover the teaching of the algorithms and data structures
module for the first three semesters of the Computer Science specialty in the Mathematics and Computer Science domain. The first part, "Algorithms and Data Structures 1", covers the following elements:
1. Introduction to Computer Science.
2. Basic Elements of Algorithms.
3. Presentation of the Algorithmic Formalism.
4. Arrays and Strings.
5. Custom Types.
We also plan to include Python programming languages in future versions. With
the aim of facilitating and widening access to this series of handouts, we plan to
produce versions in Arabic.
At the end of this work, I would first like to thank God the Almighty and Merciful, who gave me the strength and patience to accomplish this modest work.
My sincere thanks go to Messrs. Slimane Oulad-Naoui, Abdelkader Bouhani,
Chaker Abdelaziz Kerrache, Khaled Kechida, Ahmed Saidi, Messaoud Benguennane
and Misses Habiba Benabderrahmane, Wassila Belfardi, and Asma Bouchekkouf
teachers at the University of Ghardaia, who accompanied me throughout these years
in teaching the Algorithms and Data Structures module. Their footprints are clearly
visible on the content of this handout.
Finally, my thanks also go to all those who have, in one way or another, directly
or indirectly, provided their support
Basic technology cours
(university of ghardaia, 2026-06-18) DJANI Meriem
asic technology refers to fundamental technological knowledge and practices tt form
the foundation for more advanced technologies. It encompasses essential methods and systems
necessary for production and development in various inhadustries.
This course material is intended for second-year undergraduate students (LMD) in
hydraulics, civil engineering, and mechanical engineering. It is divided into four chapters, the
content of each chapter meeting the requirements of the second-year undergraduate program as
defined by the National Pedagogical Committee for the Science and Technology field.
This course will enable students to acquire knowledge of the processes for obtaining
and manufacturing parts and the techniques for their assembly.
مستويات التحليل اللساني عند الزجاجي من خلال كتاب الجمل في النحو
(جامعة غرداية, 2025) شهيناز عريفي
يهدف هذا البحث إلى اكتشاف المستويات اللسانية: الصوتية – الصرفية –التصريفية -التركيبية عند النحوي عبد الرحمان ابن إسحاق الزجاجي من خلال كتابه "الجمل في النحو". بدأت في الفصل الأول بتعريف المستويات اللسانية : الصوتية – الصرفية –التصريفية - التركيبية. أما الفصل الثاني فكان فصلا تطبيقيا قمت فيه بتحليل كتاب " الجمل في النحو ", واستخراج المستويات السابقة ، وإعطاء أمثلة عن كلّ مستوى, من خلال ما ذكره الزجاجي في كتابه هذا.
This research aims to discover the linguistic levels: phonetic, morphological, inflectional, and syntactic, according to the grammarian Abd al-Rahman Ibn Ishaq al-Zujaji, through his book “Al-Jumal fi al-Nahw”.I started in the first chapter by defining the linguistic levels: phonetic, morphological, inflectional, and syntactic.As for the second chapter, it was an applied chapter in which I analyzed the book “Al-Jumal fi al-Nahw”, extracted the previous levels, and gave examples of each level, based on what Al-Zajjaji mentioned in this boo
