A contra-rotating marine current turbine on a flexible mooring : development of a scaled prototype [PDF]

, 2008
The contra-rotating marine current turbine concept developed by the Energy Systems Research Unit at the University of Strathclyde is aimed at extracting energy in a wide range of water depths by 'flying' a neutrally-buoyant device from a flexible ...

Sound source localisation at an axial contra-rotating fan by means of PIV and rotational beamforming [PDF]

European Conference on Turbomachinery Fluid Dynamics and hermodynamics, 2019
This paper describes the investigation of a contra-rotating axial fan. It has a shroud diameter of 300 mm and a rotational speed of 1920 min-1 and 1200 min-1 for the first and the second impeller, respectively. It is designed for an air-flow rate of 0.486 m3s-1 and for total pressure difference of 180 Pa (120 Pa at the first and 60 Pa at the second ...

Experimental study of blade thickness effects on the global and local performances of a Controlled Vortex Designed axial-flow fan [PDF]

, 2011
The purpose of this work is to study the effects of blade thickness on the performances of an axial-flow fan. Two fans that differ only in the thickness of their blades were studied.

Experimental comparison between a counter-rotating axial-flow fan and a conventional rotor-stator stage [PDF]

, 2013
Based on the requirement of energy consumption level and weight and dimension restriction, compact axial machines are highly demanded in many industrial fields.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Contra-rotating marine current turbines : performance in field trials and power train developments [PDF]

, 2008
Development of a novel contra-rotating marine current turbine has been continuing at the University of Strathclyde. Continuous monitoring of blade bending loads during trials has enabled an investigation of blade-blade and blade-structure interactions ...

Heterotropic regulation and negative homotropic cooperativity

FEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Experimental study of blade rigidity effects on the global and the local performances of a thick blades axial-flow fan [PDF]

, 2010
An experimental investigation on the aerodynamic performances of thick blades axial-flow fans was carried out in this study. Two fans are considered, the first one is rotomoulded (in plastic) and the second one is milled (in aluminium). Both have exactly

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...
