The societal commitment of large Algerian companies -The SONATRACH case-
No full textOur study aims to know the CSR practices of the first company in Africa, SONATRACH, we opted for a semi-directive interview with three senior executives who answered economic questions, questions relating to the company's internal and external society, and questions relating to environmental issues. The results show that SONATRACH's responsible practices are a corporate citizen par excellence, the company opts for a responsible policy that applies international standards of behavior, ethics, and the environment, which makes this company a model for any other large company
A Comprehensive Look at the Challenges of Mobile Banking from the Consumer's Point of View
No full textMobile banking is a modern and convenient banking service that has revolutionized the banking industry by providing customers with easy access to their bank accounts and a range of banking services through their mobile devices, However, the widespread adoption of mobile banking is still hindered by several challenges. This paper examines the challenges of mobile banking and the views of consumers towards mobile banking adoption. Algerian customers have a positive attitude towards mobile banking, It is attributed to its user-friendly interface, visually pleasing design, fast and efficient management and viewing of accounts, high level of security, and the availability of various features and services. In contrast to the generally positive view of mobile banking, customers have reported low satisfaction with customer service
Development and Validation of an Open-Source Finite-Volume Method Solver for Viscoplastic Flows
No full textIn the present paper, we discuss implementation details of a free and open-source numerical solver based on the finite volume method for numerical simulation of viscoplastic non-Newtonian fluids. In addition to the fact that they are involved in many industrial applications, both their physical properties and their rheological behavior make them challenging for numerical simulation. Viscoplastic fluids are known to behave as solid unless the shear stress reaches a critical level, known as yield-stress, beyond which they behave as liquid. In most cases, both yielded and unyielded regions coexist in the fluid domain. In mathematical model of viscoplastic fluid, the constitutive equation is a non-differentiable function. This is often overcome by using the approximate constitutive equation that has a regularized form, e.g. the Papanastasiou regularization model. Using the same approach, we assess the influence of regularization parameters on simulation convergence and results accuracy. In this study, we give implementation details of viscoplastic fluid models in freeCappuccino open-source Computational Fluid Dynamics code. Moreover, we perform validation on several well known benchmark cases and compare proposed approach with those existing in published literature. We also perform a parametric analysis and show the effect of Reynolds and Bingham numbers on the extent of the yielded regions. Conclusions of the study have relevance in practical application of computational fluid dynamics to viscoplastic fluids in particular and to non-Newtonian fluids in general. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.Proceedings of the International Conference of Experimental and Numerical Investigations and New Technologies, CNNTech 2021 (Zlatibor, Serbia; June 29 - July 2, 2021

Characterising acute and chronic care needs: insights from the Global Burden of Disease Study 2019
No full textChronic care manages long-term, progressive conditions, while acute care addresses short-term conditions. Chronic conditions increasingly strain health systems, which are often unprepared for these demands. This study examines the burden of conditions requiring acute versus chronic care, including sequelae. Conditions and sequelae from the Global Burden of Diseases Study 2019 were classified into acute or chronic care categories. Data were analysed by age, sex, and socio-demographic index, presenting total numbers and contributions to burden metrics such as Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLD), and Years of Life Lost (YLL). Approximately 68% of DALYs were attributed to chronic care, while 27% were due to acute care. Chronic care needs increased with age, representing 86% of YLDs and 71% of YLLs, and accounting for 93% of YLDs from sequelae. These findings highlight that chronic care needs far exceed acute care needs globally, necessitating health systems to adapt accordingly.
