The paper is focused on the comparison of the reverse flow reactor (RFR) and of the counter-current reactor (CCR) operation, focusing the attention on the interaction between transport phenomena and chemical reactions, as well as on the analysis of the dynamic behavior. A heterogeneous mathematical model was used in order to investigate the performance of both reactor configurations. The role o...

Gene flow among populations can enhance local adaptation if it introduces new genetic variants available for selection, but strong gene flow can also stall adaptation by swamping locally beneficial genes. These outcomes can depend on population size, genetic variation, and the environmental context. Gene flow patterns may align with geographic distance (IBD--isolation by distance), whereby immi...

Diesel-operated Load Haul Dumper (LHD) vehicles are commonly used in underground coal mines. Despite their value as utility vehicles, the main drawback of these vehicles is that they generate diesel particulate matter (DPM), a known carcinogenic agent. In this work, an attempt is made to model DPM flows generated by LHDs in an underground coal mine environment for different DPM flow and intake ...

The results of modeling the dehydration drops a concentrated liquid, on example ceramics, with convective-radiation energy supply under conditions direct-flow and counter-current phase motion, as well pulsed counter-flows gas, are presented. A model for single drop is formulated based equations heat conduction source term diffusion moisture, taking into account change in its size due to evapora...
