The glass-melting furnace and the crucibles of Südel (1723–1741, Switzerland): provenance of the raw materials and new evidence of high thermal performances

Eramo, Giacomo

In: Journal of Cultural Heritage, 2006, vol. 7, no. 4, p. 286-300

Fifty crucible fragments and 10 fragments of the melting furnace of the forest glassworks of Südel (1723–1741, Ct. Luzern), were analyzed by petrographic, mineralogical and chemical techniques in order to assess the temperature reached in the melting chamber and to find out which raw materials were used to make the crucibles and the melting furnace. Since the crucibles were used in the melting...

Spatial and Seasonal Patterns of Cattle Habitat use in a Mountain Wooded Pasture

Kohler, Florian ; Gillet, François ; Reust, Stéphanie ; Wagner, Helene H. ; Gadallah, Fawziah ; Gobat, Jean-Michel ; Buttler, Alexandre

In: Landscape Ecology, 2006, vol. 21, no. 2, p. 281-295

Management-oriented models of cattle habitat use often treat grazing pressure as a single variable summarizing all cattle activities. This paper addresses the following questions: How does the spatial pattern of cattle effects vary between cattle activities in a highly heterogeneous landscape? Do these patterns change over the grazing season as forage availability decreases? What are the...

Les déterminants du choix de (dé-)localisation des entreprises en Suisse : résumé du rapport scientifique : Cahier de recherche

Baranzini, Andrea ; Ramirez, José ; Ugarte Romero, Cristian

Ce cahier étudie les choix de (dé)localisation des entreprises sur le territoire suisse entre 1998 et 2001. A l’aide des outils économétriques nécessaires, nous analysons l’impact des principaux déterminants du choix de (dé)localisation généralement considérés dans la littérature sur, d’une part, la probabilité qu’un établissement donné s’implante dans un canton donné...

A cluster analysis of multidimensional poverty in Switzerland : Cahier de recherche

Ferro Luzzi, Giovanni ; Flückiger, Yves ; Weber, Sylvain

The measurement of poverty has often been criticized for relying solely on measures of financial deprivation. Poverty being a multidimensional state, related to health, schooling, living environment, psychological state as well as social tides, care should be taken to integrate these various components to have a proper picture of poverty. This is especially true for rich countries where poor...

Groundwater components in the alluvial aquifer of the alpine Rhone River valley, Bois de Finges area, Wallis Canton, Switzerland

Schürch, Marc ; Vuataz, François-David

In: Hydrogeology Journal, 2000, vol. 8, no. 5, p. 549-563

Source, type, and quantity of various components of groundwater, as well as their spatial and temporal variations were determined by different hydrochemical methods in the alluvial aquifer of the upper Rhone River valley, Bois de Finges, Wallis Canton, Switzerland. The methods used are hydrochemical modeling, stable-isotope analysis, and chemical analysis of surface water and groundwater....

New data on the age of the installation of Urgonian-type carbonates along the northern Tethyan margin : biostratigraphy of the Chopf Member (Helvetic Alps, eastern Switzerland) = Données nouvelles sur la datation de l'installation des calcaires urgoniens le long de la marge nord-téthysienne : biostratigraphie du membre du Chopf (nappes Helvétiques, Suisse orientale)

Bodin, Stéphane ; Vermeulen, Jean ; Godet, Alexis ; Föllmi, Karl B.

In: Comptes Rendus Geosciences, 2006, vol. 338, no. 10, p. 727-733

The Chopf Member is a glauconitic, phosphate-bearing succession that occurs in the distal part of the Helvetic Alps (eastern Switzerland). The recent discovery of age-diagnostic ammonites within this horizon allows for its attribution to the lower part of the Gerhardtia sartousiana zone (middle Late Barremian). This new age corresponds to a maximal age for the onset of the Schrattenkalk Fm. in...

Communicating CSR : the practice in the top 300 companies in Switzerland

Birth, Gregory ; Illia, Laura ; Lurati, Francesco ; Zamparini, Alessandra

This paper documents the empirical results of a field study conducted among top Swiss companies. The survey investigates their practices in Corporate Social Responsibility (CSR) communication as well as their opinions about how favorable the Swiss context is for this kind of communication. Results show CSR communication in Switzerland as a practice in evolution, still needing expertise. In this...

Diversity within Borrelia burgdorferi sensu lato genospecies in Switzerland by recA gene sequence

Casati, Simona ; Bernasconi, Marco V. ; Gern, Lise ; Piffaretti, Jean-Claude

In: FEMS Microbiology Letters, 2004, vol. 238, p. 115-123

A total of 874 Ixodes ricinus ticks were collected in Switzerland to investigate the genetic diversity of the Borrelia population. We integrated to the RT-PCR method the DNA sequence analysis of a 162-bp fragment of the recA gene. Five genospecies were detected: Borrelia afzelii, Borrelia burgdorferi s.s., Borrelia garinii, Borrelia valaisiana, and...

Distribution and prevalence of Borrelia burgdorferi sensu lato in Ixodes ricinus ticks of canton Ticino (Switzerland)

Jouda, Fatima ; Crippa, Mara ; Perret, Jean-Luc ; Gern, Lise

In: European Journal of Epidemiology, 2003, vol. 18, p. 907-912

Free-living Ixodes ricinus ticks were collected from 12 different sites of canton Ticino, south of the Alps (Switzerland). Each tick was examined for the presence of Borrelia burgdorferi sensu lato (sl), the etiologic agent of Lyme borreliosis using direct fluorescent antibody assay, and isolation of the bacteria. Borreliae were characterized by PCR followed by RFLP. The...

Etude sur la diversité génétique des tiques Rhipicephalus sanguineus et Ixodes ricinus, et des agents pathogènes Rickettsia sp, Coxiella sp, Borrelia burgdorferi sensu lato, Babesia sp et le virus de l'encéphalite à tique en Suisse

Casati, Simona ; Piffaretti, Jean-Claude (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2005 ; 1842.

Dans la première partie de l'étude, nous nous sommes concentrés sur la tique Rhipicephalus sanguineus sensu lato signalée au Tessin dès les années '80 et sur les agents pathogènes transmis par ce vecteur: Rickettsia sp. et Coxiella burnetii. Nous avons confirmé par l'étude du gène rDNA 12S l'implantation de ce complexe sous la forme de deux populations distinctes: R. sanguineus s.s. et...
