Thermal Circulation Patterns and Turbulent Fluxes along Steep Mountain Slopes

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau, Eulalie Sauthier, Fabian Bärenbold

In hydrology, it is crucial to understand the atmospheric flow dynamics in mountainous terrain to predict turbulent exchanges of heat and moisture accurately at the regional scale. Under clear sky and weak synoptic conditions, these land–atmosphere interac ...

Increasing storm damage to forests in Switzerland from 1858 to 2007

Martine Rebetez

The most severe damage to forests in Central Europe occurs during winter storms caused by Northern Hemispheric mid-latitude cyclones. Storm events in the winter semesters of the past 150 years were investigated to quantify changes and evaluate whether dama ...

In vitro and in vivo photocytotoxicity of boron dipyrromethene derivatives for photodynamic therapy

Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska, Siang Hui Lim

To understand the effects of substitution patterns on photosensitizing the ability of boron dipyrromethene (BODIPY), two structural variations that either investigate the effectiveness of various iodinated derivatives to maximize the "heavy atom effect" or ...

Saturated ideal modes in advanced tokamak regimes in MAST

Jonathan Graves

MAST plasmas with a safety factor above unity and a profile with either weakly reversed shear or broad low-shear regions, regularly exhibit long-lived saturated ideal magnetohydrodynamic (MHD) instabilities. The toroidal rotation is flattened in the presen ...

Algebraic turbulence modeling in adiabatic gas–liquid annular two-phase flow

John Richard Thome, Andrea Cioncolini

The study considers algebraic turbulence modeling in adiabatic gas-liquid annular two-phase flow. After reviewing the existing literature, two new algebraic turbulence models are proposed for both the liquid film and the droplet laden gas core of annular t ...

The influence of the global photochemical composition of the troposphere on European summer smog, Part I: Application of a global to mesoscale model chain

Isabelle Bey

Elevated mixing ratios of ozone in the lower troposphere are a major summer time air pollution issue in Europe. Photochemical in-situ production is the most important source of ozone in the planetary boundary layer and has been studied extensively. However ...

Effect of sea breeze on air pollution in the greater Athens area. Part I: Numerical simulations and field observations

Hubert van den Bergh, Bertrand Calpini, Alain Clappier

Numerical simulations compared with field measurements are used to explain the effect of sea breezes on photochemical smog episodes in Athens during the Mediterranean Campaign of Photochemical Tracers on 12-14 September 1994. The numerical simulations, per ...

Vortex Convection Nonlinearity of Ac Response of Superconductors with Weak Links

Alexander Tagantsev

The electrodynamics of a high-T(c) superconductor with a network of numerous weak links (the Josephson medium) in the low-field mixed state have been analysed. The AC response to an electromagnetic wave is governed by the motion of vortices of very large s ...
