Modélisation Mathématique des Populations en Interactions
(2026) LECHLECHE Safaa; BOUKHALFA Fatima
The purpose of this thesis is the mathematical study of the dynamics of interacting
populations. We use ordinary differential equations as the main modeling tool to analyze
the local and global stability of fundamental models of Lotka-Volterra (predator prey),
competition and mutualism, then a system of three populations (rabbits, sheep, wolves).
Then we extend this study to more complex systems integrating the epidemiological di-
mension.
Analyse statistique du profil des femmes atteintes du syndrome des ovaires poly kystique
(2026) KEDADRA Douaa; KHERAFA Ahlem; MEDJAOUI Ikram
Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders affecting
women of reproductive age. It is associated with various clinical, hormonal, and metabolic
abnormalities that may impair reproductive health. This study aimed to describe the clinical,
hormonal, and metabolic characteristics of 30 women diagnosed with PCOS from the provinces
of Oran and Ain Témouchent, Algeria.
The results showed a mean age of 28.33 ± 5.89 years and a mean body mass index (BMI) of
27.41 ± 5.71 kg/m2, indicating a tendency toward overweight. Menstrual cycle disorders were
highly prevalent (93.33%), with dysmenorrhea, amenorrhea, and oligomenorrhea being the most
frequently reported abnormalities. Hirsutism was the most common clinical manifestation
(53.33%), followed by acne (46.67%) and alopecia (30%). Biological assessment revealed a mean
LH/FSH ratio of 2.02 ± 0.79 and a mean HOMA-IR index of 3.31 ± 1.39, suggesting the presence
of insulin resistance in a proportion of patients. Phenotype A was the most frequent phenotype
(36.67%). No statistically significant differences were observed between PCOS phenotypes for
the studied parameters (P > 0.05).
These findings highlight the clinical, hormonal, and metabolic heterogeneity of PCOS and
highlight the importance of early diagnosis and appropriate management to prevent reproductive
and metabolic complications associated with this syndrome.
قراءة في كتاب الشعرالجزائري الحديث: اتجاهاته وخصائصه الفنية لمحمد ناصر
(UNIVERSITY OF AIN TEMOUCHENT, 2026) جميلة ،رسطاني; عبد القادر،معمر الدين
This study aims to examine modern Algerian poetry through
Mohamed Nasser’s book Modern Algerian Poetry: Its Trends and
Artistic Characteristics 1925–1975. It focuses on the main historical
and cultural factors that contributed to its development, its major
poetic trends and characteristics, as well as its artistic features in terms
of language, style, imagery, structure, and themes. The study adopts
the historical and descriptive-analytical approaches by tracing the
development of Algerian poetry and examining the traditional
conservative trend, the romantic trend, and the new trend, with an
analysis of selected poetic models in light of Mohamed Nasser’s
study. The study concludes that modern Algerian poetry underwent a
gradual development influenced by the historical, cultural, and social
transformations experienced by Algeria, moving from traditional
forms towards greater innovation in language, imagery, structure, and
rhythm while maintaining its national and artistic identity.
قراءة في كتاب البشير الابراهيمي أدبيا لمحمد عباس
(UNIVERSITY OF AIN TEMOUCHENT, 2026) وليد،كرارمة; عبد القادر،معمر الدين
This study examines Mohamed Abbas’s book entitled Al-
Bashir Al-Ibrahimi as a Literary Writer, focusing on the literary and
artistic aspects of Sheikh Mohamed Al-Bashir Al-Ibrahimi’s personality
and highlighting his position in modern Algerian literature. The research
is based on a central question concerning the extent to which Mohamed
Abbas succeeded in highlighting the literary dimension of Al-Ibrahimi’s
personality, identifying the main characteristics of his literary writings,

and examining the critical approach adopted by the author. The study
relies on the descriptive method and consists of three chapters. The first
chapter presents the theoretical and introductory framework by
discussing Al-Ibrahimi’s life, upbringing, reformist role, and literary
position, as well as introducing Mohamed Abbas and his book. The
second chapter examines the literary features of Al-Ibrahimi’s writings
through the study of political and social essays and several stylistic and
rhetorical characteristics, including the rhetorical tendency, rhyme,
irony, satire, and the use of Arab-Islamic heritage. The third chapter
focuses on the critical value of the book by highlighting its strengths,
particularly its attention to the literary dimension, documentation of Al-
Ibrahimi’s texts, and connection between literature, reform, and politics,
while also identifying some limitations, such as the dominance of
descriptive and traditional rhetorical analysis, the limited use of modern
critical approaches, and the lack of comparison with other writers. The
study concludes that Al-Bashir Al-Ibrahimi as a Literary Writer
represents an important foundational study that contributed to presenting
Al-Ibrahimi as a literary writer alongside his roles as a scholar and
reformer, revealing the interaction between literature, reform, and
politics in his writings and opening the way for further studies using
stylistic, pragmatic, argumentative, and comparative approaches.
