Compilation d’un nouveau logiciel pour l’identification des espèces d’insectes orthoptères
(university ghardaia-jarst, 2014) Abdelkader Hadj, Seyd; Abdellahi, Kemass; Toufik, Ghrib
In this work consists in the development of a software allowing to identify some species of grasshoppers insects based on the identification key of L. CHOPARD. The software "ORTHOPTERISTE" accurately identifies a multitude of these insects (198 species spread over 19 families and 85 genders) belonging to two suborders ENSIFERA (49%) and CAELIFERA (51%). With its interactive graphical interface, guiding the user, step-by-step, the software starts by identifying the sub-order then the super-family then the family and gender, finally arriving to identify and precise the studied specie. Identification is based on etymological, morphological and physiological differences between the said insects.
Comptabilité, audit et transition : quelle adaptation pour la profession en Algérie ?
(جامعة غرداية / كلية العلوم الإقتصادية التجارية وعلوم التسيير, 23/06/2025) Assia, MOULA
Dans un environnement mondial en constante mutation, marqué par l’instabilité économique, les bouleversements technologiques, les exigences réglementaires accrues et la montée des critères ESG (environnementaux, sociaux et de gouvernance), la profession comptable se trouve à un tournant stratégique. Cette communication examine les transformations profondes qui affectent la comptabilité et l’audit à l’échelle mondiale et analyse leur résonance particulière dans le contexte algérien.En Algérie, la normalisation comptable avec l’adoption du Système Comptable Financier (SCF) témoigne d’un effort de convergence vers les normes internationales, mais elle coexiste avec des pratiques encore marquées par des logiques administratives, une faible digitalisation et un déficit de formation. La profession comptable est ainsi confrontée à une double exigence : intégrer les mutations globales (automatisation, IA, blockchain, comptabilité durable) et répondre à des défis structurels locaux (manque d’indépendance, retard technologique, faible culture de la performance).La méthodologie de ce travail s’appuie sur une analyse documentaire, une étude de cas chiffrée et une mise en perspective des écarts entre les standards internationaux et la réalité algérienne. L’objectif est d’identifier les leviers d’adaptation de la profession et les conditions nécessaires à son repositionnement stratégique, notamment en matière de gouvernance, de transparence et de responsabilité sociétale.Les résultats montrent que la profession comptable peut devenir un acteur-clé de la transition économique et durable en Algérie, à condition d’opérer une refonte de la formation, de renforcer les institutions professionnelles et de favoriser l’intégration des nouvelles technologies et des enjeux ESG dans les pratiques comptables
Contemporary Management Trends in Public Health Institutions
(جامعة غرداية, 2024-09-01) نور الدين, محجوب; عبد القادر, عكوشي
The healthcare sector emerges as a paramount facet, serving as a determinant of economic life's evolution and as a pivotal metric in assessing societal well-being. This recognition has spurred the adoption of varied governance approaches across nations, each geared towards achieving operational efficiency, service excellence, and economic efficacy concomitantly. Within the sphere of healthcare administration, diverse international experiences unveil a mosaic of management paradigms, marked by nuanced differentiations in approach. Confronted with the intricate dynamics of this environment and the imperative for expeditious outcomes from public health institutions, a conscientious effort has been directed toward the refinement of management processes. This strategic endeavor manifests an inclination towards a delegative paradigm, affording prominence to local actors. These actors, whether from the local community or internal stakeholders within these institutions, constitute a focal point in a trajectory dedicated to augmenting performance and elevating service quality.

Effet combiné de la température et de l'attaque au sulfate de magnésium sur la durabilité du mortier à base de ciment composé au laitier
(university ghardaia-jarst, 2014) Mohammed Nadjib, AZIEZ; Achour, Abderraouf; Abdelillah, Bezzar
The aim of this work is to study the effect of temperature on the durability of mortars in a sulphate- magnesium-rich environment (5% MgSO4).The strength of mortars after 12 months of immersion in the sulphate solution is evaluated by visual observation, mass variation, compressive strength, and XRD analysis. No damage was observed on the samples exposed to the sulphate solution at 20, and 50 °C, except for mortars exposed to 5 °C which are very sensitive to the formation of thaumasite. Results show that high temperature improved the mechanical strength and do not necessarily accelerate the degradation due to magnesium sulphate.

Etude de la Minéralisation et de la Granulométrie des Sols de la Sebkha de Ouargla
(university ghardaia-jarst, 2014) BOUTELLI, Med Hichem; Abdelkader, HADJ SEYD
The Sebkha of Ouargla is located north-west of the city of Ouargla in the lower Eastern Sahara. The climate of the region is known for its particularly marked by low and erratic rainfall aridity, in one hand, and the thermal amplitudes and temperatures too high on the other. This aridity is not observed only on the lack of rainfall, but also by high evaporation which is one of the current major climatic factors prevailing in the region. The latter exceeds 380 mm in July. To understand the evolution of salinity in this system, physico-chemical study of various constituent training is conducted along a north-south profile. Six piezometers were installed for sampling of surface water and groundwater monitoring groundwater level. Particle size analysis is used to determine the relative amount of different elements constituting the ground (gravels, sands, silts, clays). The size distribution curves showed that most of the samples belong to the class of arenites. This is mostly fine sand (84%) and medium sand (10%). The physico-chemical analysis of the soil 1/5 affirms the high salinity of samples. The values of electrical conductivity at 25 ° C are between 3.15 and 24.26 dS.m-1. The insoluble rate exceeds 80%, the gypsum is more than 12% while the limestone is negligible (<2%).
Freedom Of Diplomatic Communication Between Countries
(جامعة غرداية، مجلة الواحات للبحوث والدراسات ، كلية الحقوق والعلوم السياسيه, 2022) لشقر, مبروك
Tensions lead to the disruption of diplomatic relations between countries due to disputes that may arise between them, which can lead to the closure of diplomatic channels of communication, which represent the ideal tool for resolving outstanding issues, protecting the interests and develop diplomatic relations, and the tension can lead to the collapse of bilateral relations if the dispute is confined between two countries. This type of situation requires the innovation of contacts and friendly communication between countries within the framework of diplomatic channels and therefore it is very important to know the factors that create tensions. Knowing the nature of these factors obviously leads to circumventing them and avoiding their negative consequences.

(جامعة غرداية / كلية العلوم الإقتصادية التجارية وعلوم التسيير, 2025-06-23) أمينة, بن غفور
قد أدى القانون العضوي المتعلق بقوانين المالية إلى إصلاح النظام المالي القائم بشكل عميق. وبالإضافة إلى إدخال هيكلة جديدة لميزانية الدولة، فإن هذا الإصلاح سيقدم أساليب إدارية جديدة في الإدارات، تعتمد على الأداء. وبهذا القانون ستنتقل الدولة من منطق الوسائل إلى منطق النتائج، بحيث يكون كل دينار تنفقه أكثر فائدة. حتى الآن، كان البرلمان أكثر اهتماما بالموارد المخصصة لسياسة ما من اهتمامه بالنتائج الملموسة التي تم الحصول عليها بفضل هذه الموارد.La loi organique relative aux lois de finances a profondément réformé le dispositif établi en matière budgétaire. Outre une nouvelle architecture du budget de l'Etat, cette réforme mettra en place de nouveaux modes de gestion dans les administrations, reposant sur la performance. Avec cette loi, l’Etat passera d’une logique de moyens à une logique de résultats, afin que chaque dinar dépensé soit plus utile. Jusque là, le Parlement s’intéressait davantage aux moyens consacrés à une politique qu’aux résultats concrets obtenus grâce à ces moyens..
