“…We wish to share with the students our exultation over all the beautiful and rich phenomena of the God's creation. We continue our work (Duda et al, 2019) (Duda, Uruba, & Yanovych, 2022) by simple apparatus for demonstration of the jet flow, which shows not only jet itself, but also the time-irreversibility on a simple case.…”

This book contains the full text of papers and posters presented at the International Conference on Education and New Developments (END 2024), organized by the World Institute for Advanced Research and Science (WIARS).Education is a fundamental right that accompanies us from the very beginning of our lives. It encompasses every experience we encounter, influencing and shaping our thoughts, emotions, and actions. Whether we engage in formal education within classrooms or learn from the world around us, the process of acquiring knowledge plays a vital role in our personal growth and development. It equips us with the tools to navigate the complexities of life, broadens our perspectives, and empowers us to make informed decisions. This International Conference seeks to provide some answers and explore the processes, actions, challenges and outcomes of learning, teaching and human development. Our goal is to offer a worldwide connection between teachers, students, researchers and lecturers, from a wide range of academic fields, interested in exploring and giving their contribution in educational issues.We have brought together a diverse group of individuals with various backgrounds to contribute their unique perspectives and knowledge on Education. By including people from different nationalities and cultures, we aim to create a rich plethora of experiences that can broaden our understanding of human nature and behavior. The exchange of ideas and experiences among our participants helps to cultivate personal and academic development, providing a platform for the exploration of new insights and discoveries.END 2024 received 729 submissions, from more than 50 different countries, reviewed by a double-blind process. Submissions were prepared to take form of Oral Presentations, Posters, Virtual Presentations and Workshops. The conference accepted for presentation 284 submissions (39% acceptance rate).

“…According to our previous attempt in this direction published in conference paper [1], we observe that the students are generally clever enough to understand and to pass the exam. However, they lack of motivation -there is lot of students, who learn just the minimum to pass the exam for 3 (the worst grade allowing passing), although their abilities are higher.…”

Four simple demonstration experiments are presented. They are used as a support in the teaching of Fluid Mechanics I (a compulsory lecture at the University of West Bohemia in Pilsen). All mentioned experiments use the rheoscopic fluid obtained as a water solution of mica powder to visualize the flow in a esthetic way, which, as we hope, has a potential to attract students attention. The experiments are: demonstration of Bernoulli equation in a widening and narrowing channel, Taylor-Couette flow, the effect of viscosity to the scales and decay of turbulence, and the Galilean transformation inside an axial compressor.

A system that requires slurry handling such as reactive crystallization is not usually compatible with continuous flow synthesis due to the risk of clogging. Here we suggest the use of a Taylor vortex flow reactor to achieve a robust process for imination with reactive crystallization under continuous flow conditions. A Taylor vortex flow reactor realizes high shear stress and mixing efficiency, which accelerate the timing for nucleation of target imines. This effect enabled precise control of nucleation in reactive crystallization and successfully showed the mitigation of significant adhesion to the flow reactor through a long-run experiment for 120 min. This work gives one of the practical strategies to remove the limitation of slurry handling that is not suitable for continuous flow synthesis and increase the performance of flow chemistry.
