This article examines the mechanisms for intensifying heat and mass transfer processes in fluidized bed apparatuses. Primary focus is placed on the implementation of a lateral flat jet as a method for controlling bed hydrodynamics. The study analyzes the impact of additional jet influence on flow structure, the elimination of stagnant zones, and the enhancement of the heat transfer coefficient,

In this study, the classification of preferred and rare barley varieties based on aeration velocity was investigated for the production of protein-enriched early-maturing pasta raw materials. The goal is to reduce the repeated grinding and sifting stages of traditional technology by sorting fractions and other components containing starch, β-glucan, dietary fiber, and ash at an artificial wind speed.

At the stage based on protein enrichment, the "Istak" variety was used; after the first fractionation cycle, the protein content in the "Istak" variety increased by 2.13 times. Repeated cycles led to an even higher yield of dry protein for the "Istak" variety, resulting in an effective yield of high-protein fractions of 47–52%,

This paper analyzes the methodological aspects of integrating modern immersive technologies and digital data acquisition systems into the secondary school chemistry curriculum. Addressing the limitations of traditional visual aids, the study explores the pedagogical effectiveness of virtual laboratories and PASCO STEM hardware within a tripartite didactic framework encompassing "macro-submicro-symbolic" levels of representation. The empirical validation conducted via a controlled pedagogical experiment involving 9th-grade students indicates a statistically significant enhancement in conceptual understanding and analytical thinking. The results are mathematically validated using Student's t-test (tv = 3.42 > tcrit = 2.01, α = 0.05). The article offers an integrated matrix and practical guidelines for science educators to transition from passive computerization to an active, inquiry-based digital learning environment.
