Cette étude analyse les qualités physiques et physiologiques des jeunes handballeurs sénégalais des sélections nationales U18 et U20, dans le but d’évaluer leur compatibilité avec les exigences du handball de haut niveau. Un échantillon de trente-trois (33) athlètes a été soumis à une batterie de tests physiques (vitesse, puissance, force, agilité, endurance, souplesse) et physiologiques (fréquence cardiaque, pression artérielle, électrocardiogramme).

This article attempts to examine the relationship between the peasantry and armed groups during conflicts in the Dogon region of central Mali. The study highlights, on the one hand, the contexts in which armed conflicts occur and, on the other hand, the socio-economic relationships between populations and armed groups. Thus, these conflicts are initially perceived as a source of despair and destruction of the socio-economic activities necessary for the survival of peasants.

This research explores the pivotal role of Artificial Intelligence (AI)-based smart façades in advancing Saudi Arabia’s Vision 2030 objectives, emphasizing sustainability, energy efficiency, and quality of life. The study integrates AI algorithms with adaptive façade technologies to create intelligent building systems that dynamically respond to environmental and occupancy changes.

The natural right to water, earth and air as basic human needs is being increasingly eroded in our time. Most people are becoming more and more dependent on those - be they the super-rich or multinational corporations - who postulate and exercise a right of disposal over them. The desire to own and have, a new kind of materialism, is a hallmark of our civilization, accompanied by increasing inequality. A situation similar to that before the French Revolution. A revolution of consciousness is therefore necessary if real revolutions are to be avoided.

En entreprenant cette recherche sur « le profil des agents de l’Etat affectés dans les services de planification de l’éducation des sous provinces éducationnelles de Kinshasa », nous avons voulu savoir si ces agents exercent vraiment le travail destiné aux planificateurs de l’éducation dans leurs services.

The present study aimed to develop and evaluate sustained release formulations of Lansoprazole capsules using solid dispersion and formalin-treated gelatin capsules to enhance solubility and achieve controlled drug delivery. Preformulation studies, including organoleptic characterization, solubility testing, and FTIR analysis, confirmed the drug’s poor aqueous solubility, stability, and compatibility with selected excipients.

Many students suffer from heavy stress when it comes to their exams, often disabling them from performing their best due to a fear of failure. This is significant because it affects one’s health, grades, and future endeavors. But how does exam stress affect students’ exam performance? Our objective is to decipher which physiological indicators affect the exam score the most.

This paper discusses the Software Defined Radio-based Digital Transceiver, focusing on the 256-QAM transceiver used exclusively in 5G. The transceiver discussed here is software-defined, quite unlike that used in 5G.The 5G transceiver switches to the 256-QAM Modulation scheme when the received power is high. This paper uses the SIMULINK model to discuss the 256-QAM Modulation scheme, where the whole transceiver is designed and implemented on an FPGA. The speed and reconfigurability of the FPGAs are the driving forces for such an implementation.
