The influence of bailers on the hydrodynamic performance of the seaplane

Zhongguo Jianchuan Yanjiu, 2021
ObjectivesThe hydrodynamic performance under different bailer conditions based on numerical and experimental methods was investigated. MethodsThe hydrodynamic performance of the seaplane with different displacements under different speeds was studied using an experimental method, and the viscous flow field of the seaplane under three conditions（without

Process-based karst modelling to relate hydrodynamic and hydrochemical characteristics to system properties [PDF]

, 2013
More than 30% of Europe's land surface is made up of karst exposures. In some countries, water from karst aquifers constitutes almost half of the drinking water supply.

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

FEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...
