Cours Reaction Engineering I: Non-Ideal Reactors and Bioreactors
(University of El Oued, 2026) Ben Seghir Bachir
This course focuses on the analysis and design of non-ideal chemical reactors, where real flow behavior deviates from ideal models such as the Plug Flow Reactor (PFR) and the Continuous Stirred Tank Reactor (CSTR). To describe these deviations, the concept of Residence Time Distribution (RTD) is introduced as a key tool. RTD provides a statistical description of how long fluid elements remain inside the reactor, allowing engineers to detect flow irregularities such as dead zones, bypassing, and recirculation. It is experimentally determined using tracer techniques and mathematically described through functions like E(t), F(t), mean residence time, and variance. By combining RTD with reaction kinetics, it becomes possible to accurately predict reactor performance, including conversion and yield. The course also covers hydrodynamic modeling of real reactors using models such as tanks-in-series and axial dispersion, as well as the role of dimensionless numbers like the Péclet and Damköhler numbers. In addition, it introduces bioreactors, which are used for enzymatic and microbial processes, emphasizing mass transfer, mixing, and reaction kinetics. Key models such as Michaelis–Menten and Monod equations describe enzymatic reactions and microbial growth. The course highlights the importance of coupling reaction kinetics, mass transfer, and fluid dynamics in reactor design, showing that real reactor behavior results from the interaction of these phenomena rather than ideal assumptions.
The Pivotal Role Of Central Bank Digital Currencies (cbdcs)

This study looks at how they can help achieve the United Nations Sustainable Development Goals (SDGs) by showing connections between CBDC features and SDG targets. Well-designed CBDCs can improve development outcomes. In countries focused on financial inclusion, CBDCs with tiered identity verification could raise adult access to financial services by 15 to 20%. In areas seeking better governance, CBDCs may reduce illicit financial activities by 5 to 10%. Additionally, they can improve the efficiency of social benefit programs by 30 to 45%. The study suggests a “Governance by Design” framework to embed sustainable development goals in CBDC architecture. It reviews design approaches in countries like China, Nigeria, Sweden, and the Bahamas, noting risks and offering solutions. A well-governed CBDC can promote a fairer and more transparent financial system. The study ends with recommendations for policymakers to tackle challenges and enhance outcomes.

The current study aimed to identify the effect of leadership behavior styles (the democratic leadership style, the autocratic leadership style, the free leadership style) on the morale of the employees of the Tizi-Mascara Dairy, This study relied on the descriptive approach, in addition to using the questionnaire as a tool for data collection. A random sample of 40 employees in the institution was selected, For data processing, we use the statistical package spss 25, Several statistical methods were used for data processing, and the simple linear regression method was used to test the hypotheses of the study. The results of the study showed that the dominant leadership style in the organization from the employees point of view is the democratic leadership style, and the morale levels were high, The results of the study also showed a statistically significant effect of the democratic leadership style on the employees morale of the Tizi-Mascara Dairy, In addition to the absence of a statistically significant effect of the autocratic leadership style and the free leadership style on the employees morale in the Tizi-Mascara Dairy
مساهمة إدارة المعرفة في تحقيق الميزة التنافسية للمؤسسات الاقتصادية

This study aims to highlight the reality of knowledge management in economic institutions and its contribution to achieving competitive advantage. This study was conducted through a field study of a sample of private medical clinics in the state of El Oued. To achieve this goal, the descriptive approach was adopted in the theoretical aspect and the analytical approach in the field study. A questionnaire was distributed to 82 employees, and the results were analyzed using SPSS v27 . Knowledge management is an essential element in achieving a competitive advantage for the private medical clinics under study. However, the dimensions of its components affect their success. There is a statistically significant impact of knowledge management on achieving a competitive advantage for the institutions under study at the significance level (α≤0.05). We concluded with a set of recommendations, the most important of which are: investing in a technological infrastructure that facilitates the collection, storage, and sharing of knowledge, thus strengthening knowledge management systems within medical clinics; and establishing periodic evaluation mechanisms to measure the impact of knowledge management on competitive advantage and performance, which helps in modifying policies and making data-driven decisions.
