On Improvement of Characteristic Instability and Internal Flow in Mixed Flow Pumps

Journal of Fluid Science and Technology, 2008
The difference of pump characteristics between two kinds of mixed flow pumps with low specific speed of 350 (min-1, m3/min, m), which have the same impeller and the different diffuser vanes, is presented in the present paper.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

FLOW CHARACTERISTICS OF SKIMMING FLOW IN A STEPPED CHANNEL

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2004
Recently, research onto the hydraulics of stepped chutes was driven by needs for better design guidelines (OHTSU and YASUDA 1997, CHANSON and TOOMBES 2002, BOES and HAGER 2003). Although stepped channel flows are characterized by intense turbulence and strong flow aeration, most studies did not investigate the turbulence characteristics. In this study,

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Characteristic rainfall for warning of debris flows

, 2010
A characteristic rainfall is introduced to overcome the difficulties encountered in determining a critical rainfall value for triggering debris flow. The characteristic value is defined as the rainfall at which debris-flow occurrence probability shows a ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Vortex valve

EPJ Web of Conferences, 2018
The paper deals with a flow field inside the so-called vortex valve, used as an outlet device on retention reservoirs for retention of rainstorms and later slow outflow into sewerage etc. The system is very simple, without moving parts.
