Introduction to special issue on high speed solar wind streams and geospace interactions (HSS-GI) [PDF]

, 2009
This special issue of the Journal of Atmospheric and Solar-Terrestrial Physics is devoted to research into high speed solar wind streams (HSSs) and their effects on the region of near-Earth space commonly known as ‘geospace’.

Study on the Influence of a Powered Nacelle on the Wake Vortex Characteristics of Wide-Body Aircraft

Aerospace
The aircraft wake vortex is an important factor affecting flight safety; as an important part of the aircraft, the powered nacelle will inevitably have an important impact on the aircraft wake vortex, so it is of great practical significance to research ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Study on the Influence of Suction Parameters on the Effectiveness of Hybrid Laminar Flow Control for Two-Dimensional Airfoils

Aerospace
Boundary layer suction is a critical technique in hybrid laminar flow control (HLFC) for delaying transition and reducing drag. While the effectiveness of suction is well-established, systematic studies on the parametric optimization of suction hole ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Economic Development Impacts of High Speed Rail [PDF]

This paper reviews the state of high-speed rail (HSR) planning in the United States c. 2010. The plans generally call for a set of barely inter-connected hub-and-spoke networks. The evidence from US transit systems shows that lines have two major impacts.

High Speed Cities

TeMA: Journal of Land Use, Mobility and Environment, 2008
Integrazione tra le discipline che studiano le trasformazioni urbane e quelle che affrontano le tematiche del governo della mobilità per la costruzione di un nuovo corpus di conoscenze teorico-metodologiche che, superando gli steccati che segnano il confine – del tutto apparente – tra queste discipline, sia in grado di formulare soluzioni nuove ai ...
