Medium-Scale Traveling Ionospheric Disturbances and Plasma Bubbles Observed by an All-Sky Airglow Imager at Yonaguni, Japan

Terrestrial, Atmospheric and Oceanic Sciences, 2009
We report on night time air glow imaging observations of the low latitude ionosphere by means of a 630-m all-sky imager in stalled in March 2006 at Yonaguni, Japan (24.5°N, 123.0°E; 14.6°N geomagnetic), about 100 km east of Taiwan.

Bistable Switching of π‐Conjugation in a Dithienylethene‐Bridged Luminescent Trityl Diradicaloid

Angewandte Chemie International Edition, EarlyView.
Photoswitches that affect π‐conjugation offer a powerful strategy for external manipulation of luminescent diradicals. Dithienylethene‐linked persistent trityl diradicaloids, DTE‐TTM2 and F6‐DTE‐TTM2, exhibit bistable switching of their optical, electrochemical and magnetic properties.

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Self‐Transcendence and Self‐Enhancement Values as Drivers of Eco‐Travel Behavior. Implications for Business Strategies for Eco‐Tourism Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT Ecotourism encourages environmentally friendly travel; however, little is known about the underlying value systems influencing travelers' choices and actions. This study uses a mixed‐method methodology that combines post hoc qualitative analysis with a large‐scale quantitative survey to examine the influence of multiple value dimensions on ...
