Relating forest damage data to the wind field from high-resolution RCM simulations: case study of Anatol striking Sweden in December 1999

Nilsson, C. ; Goyette, Stéphane ; Bärring, L.

In: Global and Planetary Change, 2007, vol. 57, no. 1-2, p. 161-176

Forestry is of major economical importance in Europe, and recent devastating windstorms have pinpointed the vulnerability of this economic sector to windstorms. Forest damage is an important economic issue at a country level and may become even of larger concern under future conditions following global warming. An underlying question is to what extent the storm damage is due to changes in the...

Future extreme events in European climate: an exploration of regional climate model projections

Beniston, Martin ; Stephenson, David B. ; Christensen, Ole B. ; Ferro, Christopher A. T. ; Frei, Christoph ; Goyette, Stéphane ; Halsnaes, Kirsten ; Holt, Tom ; Jylhä, Kirsti ; Koffi, Brigitte ; Palutikof, Jean ; Schöll, Regina ; Semmler, Tido ; Woth, Katja

In: Climatic Change, 2007, vol. 81, no. Supl. 1, p. 71-95

This paper presents an overview of changes in the extreme events that are most likely to affect Europe in forthcoming decades. A variety of diagnostic methods are used to determine how heat waves, heavy precipitation, drought, wind storms, and storm surges change between present (1961–90) and future (2071–2100) climate on the basis of regional climate model simulations produced by the...

Web branding at Vietnamese manufacturing enterprises

Huong, Luc Thi Thu ; Meier, Andreas (Dir.) ; Vanetti, Maurizio (Codir.)

Thèse de doctorat : Université de Fribourg, 2007.

The research stream on Website quality has evolved in recent years. Although several research issues have been addressed, there remain gaps in literature about the facilitators of Website as a brand. Therefore, the general purpose of this study is to identify, describe and analyze factors that have had an impact on customer awareness and loyalty to a Website. Based on the literature review, a...

1,4-Dimethylenespiropentane: a unique model system for studying fermi resonance in raman optical activity

Hug, Werner ; Haesler, Jacques ; Kozhushkov, Sergei I. ; Meijere, Armin de

In: ChemPhysChem, 2007, vol. 8, no. 8, p. 1161 - 1169

The C₂-symmetric title compound, a small, rigid hydrocarbon molecule with two distinct, strongly interacting vibrational chromophores, represents a unique model system for testing computational approaches to Raman optical activity (ROA) beyond the isolated molecule and the harmonic approximation. We show that the experimental Raman and ROA spectra are marked by the presence of strong Fermi...

Photoacylation of alcohols in neutral medium

Débieux, Jean-Luc ; Cosandey, Anne ; Helgen, Céline ; Bochet, Christian G.

In: European Journal of Organic Chemistry, 2007, p. 2073 - 2077

We report here conditions which allow the photoacylation of primary, secondary and tertiary alcohols with N-acetyl-5,7-dinitroindoline under exceptionally mild conditions, at wavelengths harmless to most functional groups, including otherwise photosensitive ones.

Quantitative self-sensitized photooxidation of 1,2-diarylcyclobutene derivatives by singlet oxygen

Kühni, Joël ; Debieux, Jean-Luc ; Belser, Peter

In: Synthesis, 2007, p. 1421-1425

Ligands 1 and 2 underwent quantitative photooxidation when they were reacted with singlet oxygen sensitized by methylene blue. However, the quantitative reaction became self-sensitized for the compound Ru(1) wherein the ruthenium complex acted as a sensitizer.

The Drosophila larva as a model for studying chemosensation and chemosensory learning: a review

Gerber, Bertram ; Stocker, Reinhard F.

In: Chemical Senses, 2007, vol. 32, no. 1, p. 65-89

Understanding the relationship between brain and behavior is the fundamental challenge in neuroscience. We focus on chemosensation and chemosensory learning in larval Drosophila and review what is known about its molecular and cellular bases. Detailed analyses suggest that the larval olfactory system, albeit much reduced in cell number, shares the basic architecture, both in terms of...
