Flow structure

The variation of multiple circular cylinders' drag coefficient was investigated using numerical methods. Moreover, the particle tracking simulation was also performed to show the flow structure and how particles move inside the cylinder array. It was found that the density and location of cylinders have a significant influence on the fluid forces, flow structure, and particle movement inside them.

This study investigates how different test parameters—such as flow rate, soil type, moisture content, and confining conditions—affect the erosion behavior of soils. Through controlled hydraulic erosion tests, the research identifies key factors influencing critical shear stress and erosion rates. The findings aim to enhance understanding of soil stability in engineering applications and inform the design of erosion-resistant structures.

In this study, Partial Least Square – Structural Equation Modeling (PLS-SEM) was used to analyze data from the questionnaire survey of 363 customers who are familiar with live streaming platforms in Vietnam. By using SmartPLS for data empirical evaluation and hypotheses testing, research shows that the social presence of a live streaming platform and scarcity have a positive impact on consumer’s flow states, hence inducing consumers’ impulsive buying behaviors.

The formation and development of large-scale structures are primary research subjects in the study of turbulent mixing layers. Visualizing these structures based on published experimental data enhances the understanding of complex flow behaviors, which is the main objective of this article. The authors employed a two-point statistical correlation method to evaluate the size of large vortex structures along the interaction region.

This research proposes strategic solutions for attracting Foreign Direct Investment (FDI) to develop eco-industrial parks in the Red River Delta region through 2030, with a vision for 2050. The author's proposed solutions are grounded in a comprehensive analysis of the current status and developmental trends of eco-industrial park models, forecasted impacts of international and domestic contexts on FDI flows, and the competitive advantages of the Red River Delta region in attracting FDI specifically for eco-industrial parks.

This study aims to use CFD analysis of CT scan data from the nasal cavities of a range of older Asian males to investigate the impact of geometric variations between older nasal cavities on the airflow structures and airconditioning capacity of the nasal cavity. Air flow mechanisms, heat transfer rates and humidification efficacy are analysed in order to arrive at a more precise understanding of the role of nasal geometry in the presentation of respiratory ailments.

This study uncovers a wide range of complex transport dynamics in transiently forced aquifers that has profound implications for the understanding and quantification of solute transport in these important groundwater systems. And the results in this thesis predict that complex transport structures and dynamics arise in natural transiently forced aquifers around the world. When such dynamics do arise, it will lead to mixing and reactive transport patterns that are very different from those predicted by conventional Darcy flow models.

The roles of His181, His184 and Tyr186 in PETN reductase have been examined by mutagenesis, spectroscopic and stopped-flow kinetics, and by determination of crystallographic structures for the Y186F PETN reductase and reduced wild-type enzyme—progesterone complex. Residues His181 and His184 are important in the binding of coenzyme, steroids, nitro-aromatic ligands and the substrate 2-cyclohexen-1-one.

Purified recombinant proteins fromSynechocystisPCC6803 were used to show that the magnesium chelatase ChlH subunit stimulates magnesium protoporphyrin methyltransferase (ChlM) activity. Steady-state kinetics demonstrate that ChlH does not significantly alter theKmfor the tetrapyr-role substrate. However, quenched-flow analysis reveals that ChlH dramat-ically accelerates the formation and breakdown of an intermediate in the catalytic cycle of ChlM.
