Item type:Item, Controle intelligent et systemes autonomes : application a la robotique(Université Sétif 1 - Ferhat ABBAS , Faculté des Sciences, 2006) KARA , Kamel; BENMAHAMMED , Khier EncadrantThe predictive control has become currently a precious tool for control in various domains. It is well known and largely studied in the case of linear systems. The extension of this technique for the control of non linear systems has recently been the subject of many researches, where several algorithms were proposed. The objective of this work is to consider the application of neural networks to this technique of predictive control. This work deals with the most significant difficulties met during the development of these structures of nonlinear predictive control; that is obtaining a nonlinear model and a fast implementation of the control algorithm for real time applications. Thus, a part of this work is devoted to the identification of nonlinear systems using neural networks. The other part, deals with the problem of the implementation of the predictive control law when using a neural model for the prediction of a future behaviour of the system. In order to highlight the contribution of the proposed methods, simulation examples were considered.Item type:Item, Synthese Verte Des Nanoparticules D’argent A L’aide Du Romarin(Université Setif1 Ferhet Abbas.Faculté de Medecine, 2026) BOUGHITA , Rafik Abdenour; BOUDAROUAZ , Hadjer; KORICHI ,Samia; KHABABA.A , (Encadrante)Nanotechnology is a multidisciplinary field involving several scientific disciplines. Among the most widely used nanomaterials, silver nanoparticles (AgNPs) hold a significant place due to their numerous biomedical and pharmaceutical applications. The green synthesis of AgNPs using plant extracts represents an eco-friendly and sustainable alternative to conventional synthesis methods. This study investigates the biosynthesis of silver nanoparticles using Salvia rosmarinus officinalis extract. The formation of AgNPs was confirmed by UV-Visible spectroscopy through the appearance of a characteristic peak around 450 nm. The results also demonstrated the influence of several factors, including reaction time, light exposure, silver nitrate concentration, and plant extract volume. Infrared spectroscopy analysis highlighted the role of bioactive compounds present in Salvia rosmarinus officinalis in the reduction and stabilization of silver nanoparticles.Item type:Item, Etude Ethnobotanique Et Activites Biologiques Du Chardon marie Dans La Region De Setif(Université Setif1 Ferhet Abbas.Faculté de Medecine, 2026) BENABBAS , Chaima; DEBAB , Imen; ADIMI , Leila Zade (Encadrante)Asteraceae family, is widely recognized for its hepatoprotective properties attributed to silymarin, a complex of flavonolignans concentrated in its seeds. Despite its well-established therapeutic value, its traditional uses in the Sétif region (Algeria) remain insufficiently documented. This study aimed to assess the level of knowledge and ethnobotanical practices related to Silybum marianum among the population of Sétif, to investigate the antimicrobial activity of its extracts, and to develop an oral dosage form (capsules) for pharmaceutical valorization. An ethnobotanical survey was conducted among 100 participants (February–April 2026) using a structured questionnaire, with statistical analysis performed using IBM SPSS. Ethanolic extraction (70%) of seeds by maceration for 24 hours yielded a dry extract with 4% yield. Antimicrobial activity was evaluated using disk and well diffusion methods against four bacterial strains and two fungal strains. Capsules containing 140 mg of silymarin were formulated using lactose as an excipient. Results showed that 46% of participants were familiar with the plant and 80% used herbal medicine. Seed infusions were the most common preparation, mainly for hepatic disorders. The extract showed activity only against Staphylococcus aureus (10–14 mm), with no effect on other strains. These findings confirm the therapeutic potential of Silybum marianum and highlight the need for further pharmacological investigations.Item type:Item, Optimisation Dans La Pratique Des Transfusions Sanguines Pour Une Meilleure Sécurité Des Patients Au CSW CHU De Setif(Université Setif1 Ferhet Abbas.Faculté de Medecine, 2026) MELAIM , Selma; MAHROUK , Nada; MILI , Samah Aya Inès; ABBASSEN , Nabila (Encadrante)The objective of our study was to evaluate transfusion practices at the Wilaya Blood Transfusion Center (WBTC) of SÉTIF, to optimize patient safety and improve the quality of care. This prospective study was conducted over a period of three months and included 3,405 blood donations. It covered the entire transfusion chain, including donor reception, medical interviews, blood collection, serological testing (HIV, HBV, HCV, and syphilis), immunohematological testing (ABO and Rh blood grouping, phenotyping, and hemolysin screening), as well as preparation, quality control, storage, and distribution of blood components. The results confirm an overall satisfactory level of transfusion safety, while highlighting the persistence of certain areas requiring improvement.Item type:Item, Utilisation Du Quantiferon Dans La Strategie de Depistage De La Tuberculose Latente Avant Initiation Des Traitements Par Anti tnf(Université Setif1 Ferhet Abbas.Faculté de Medecine, 2028) HALIMI , Manel; TENSAOUTI , Chanez; BENKARI , Lamia (Encadrante)Tuberculosis (TB) remains a major public health problem worldwide and particularly in Algeria, a country with intermediate endemicity. Latent tuberculosis infection (LTBI) represents a significant risk of reactivation in patients with chronic inflammatory diseases on anti-TNF therapy due to the key role of TNF-α in maintaining granulomas. The main objective of this study is to evaluate the QuantiFERON-TB Gold Plus (QFT-Plus) test for screening LTBI before anti-TNF treatment in patients with chronic inflammatory diseases at Sétif University Hospital. This retrospective observational study included 117 patients. All underwent pre-therapeutic assessment with clinical exam, chest X-ray, and QFT-Plus (with or without IDR). QFT-Plus was positive in 9 patients (7.7%). Concordance with IDR was very good and indeterminate results were very low (<1%). Anti-TB prophylaxis was started in all positive cases. These results highlight QFT-Plus as a reliable and practical tool, especially in BCG-vaccinated individuals, and confirm the importance of systematic screening before anti-TNF therapy in Algeria
