TiAlN coated carbide tools prepared by arc ion deposition (AIP) can be applied to high-speed, full-dry and semi-dry cutting due to their high thermal oxidation resistance and high wear resistance and low friction coefficient, which can greatly increase productivity. To improve the adhesion strength of TiAlN films, a TiAl intermediate layer was introduced between the substrate and the TiAlNcoating, and the effect of the thickness of the intermediate layer on the adhesion strength of TiAlN films was simulated and experimentally verified.

This study aimed to evaluate students’ perspectives on the institutional support, training, and ethical use of AI tools in academia. Using a quantitative cross-sectional survey design, data were collected from 108 students across diverse academic disciplines, with a focus on their experiences and perceptions of AI tools. The study examined institutional resources, including workshops, written guidelines, and online resources, as well as students' preparedness and views on AI’s impact on academic productivity.

This study examined the organizational commitment of Bureau of Corrections officers at Iwahig Prison and Penal Farm in Puerto Princesa City, Palawan. It explored the relationship between work values, self-actualization, and job satisfaction, aiming to construct a structural equation model (SEM) to understand their collective influence on organizational commitment. The research design employed a quantitative, correlational approach, utilizing validated and pre-tested Likert-scale instruments to collect data from 522 officers through total enumeration sampling.

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.
