Morphogenèse des vallées sèches du Jura tabulaire d'Ajoie (Suisse) : rôle de la fracturation et étude des remplissages quaternaires

Braillard, Luc ; Caron, Christian (Dir.) ; Monbaron, Michel (Codir.)

Thèse de doctorat : Université de Fribourg, 2006 ; no 1517.

This work tackles the origin of the dry valleys of the tabular Jura of Ajoie (northwestern Switzerland) according to a new and multidisciplinary approach, in particular thanks to the geological information collected during the last twenty years in relation with the construction of the highway A16. Once the geomorphological framework has been set, the various morphogenetic hypothesis found in the...

Vinaigrées ou obsolètes, quel avenir pour les archives film et vidéo d'une institution ? : le cas du Conseil oecuménique des églises

Praz, Renaud ; Roulet, Aurélie ; Dubosson, Françoise (Dir.) ; Léger,Denyse (Codir.)

Mémoire de diplôme HES : Haute école de gestion de Genève, 2005 ; TDB 2016.

Le Conseil oecuménique des Églises est une organisation non gouvernementale réunissant 347 Églises dont le siège administratif est à Genève. Il possède environ 2’000 enregistrements film et vidéo. Ces supports risquent de ne plus être lisibles dans quelques années. Le Service Bibliothèque et Archives du COE nous a demandé de définir et d’appliquer un traitement archivistique...

Contribution à l'étude du pergélisol de montagne en zone marginale

Delaloye, Reynald ; Monbaron, Michel (Dir.)

Thèse de doctorat : Université de Fribourg, 2004 ; no 1441.

The main objective of this thesis is the identification of mechanisms controlling the occurrence and the evolution of mountain permafrost in peripheral areas, i.e. where the presence of permafrost is strongly discontinuous, isolated, or even uncertain. This area has not been greatly studied so far. As investigations relating to the effects of climate warming on the alpine environment multiply,...

Le financement public de la R&D en Suisse 1969-1998

Lepori, Benedetto

This report presents basic data on the public financing of research and development in Switzerland from 1969 to 1998. Using the original data from the Swiss Federal Office for Statistics, the author has corrected and completed the time series for the different categories of expenditures, so that to allow for long-term comparison: the considered categories are the research of the public sector,...

Analyse de l'activité de glissements de terrain et relation avec les conditions climatiques : exemples dans les Préalpes fribourgeoises (Suisse)

Oswald, Daniel ; Caron, Christian (Dir.) ; Raetzo, Hugo (Codir.) ; Müller, Imre (Codir.) ; Strasser, André (Codir.)

Thèse de doctorat : Université de Fribourg, 2003 ; no 1417.

Deep landslides (> 10 m) are generally characterized by phases of acceleration alternating with periods of lull, but most often lack real stabilization. Due to the continuous movement, it is difcult to evaluate the evolution of the activity. Therefore, a new methodology has been developed in order to precisely identify the sub-recent (20th century) and present evolution of deep landslide...

Organisation of genetic variation in multinucleate arbuscular mycorrhizal fungi

Kuhn, Gerrit ; Sanders, Ian R. (Dir.)

Thèse de doctorat : Université de Lausanne : 2003.

Arbuscular mycorrhizal fungi (AMF) are root symbionts with about 80% of all known species of vascular land plants. AMF are ecologically important because of the benefits that they confer to plants. Molecular studies on AMF showed that rDNA sequences were highly variable between species and within species. Because AMF are coenocytic and multinucleate there are several possibilities how this...
