Des abeilles, des ruches et des humains : les Centres apicoles : des acteurs de la réalisation de la filière apicole au Burkina Faso

Boila, Zeno ; Fresia, Marion (Dir.) ; Aebi, Alexandre (Codir.)

Mémoire de master : Université de Neuchâtel, 2018 ; NET 900/431.

La présente étude se focalise sur les processus de structuration de la filière apicole au Burkina Faso et sur le rôle joué par les Centres apicoles ; des structures nées en tant qu’unités de transformation des premiers projets de développement en apiculture élaborés par certaines ONG étrangères durant la fin des années 1990 et le début des années 2000. En partant du constat...

We are ready for faunistic surveys of bdelloid rotifers through DNA barcoding : the example of Sphagnum bogs of the Swiss Jura Mountains = Listos para revisiones faunísticas de rotíferos bdelloideos por DNA barcoding: el caso de las turberas de Sphagnum de las montañas del Jura suizo

The identification of biological diversity through DNA barcoding and metabarcoding of the organisms living in the field has the potential to revolutionise the way biological surveys and monitoring are performed. Yet, we still do not know if the current representativeness of the reference database of DNA sequence data is sufficient to allow such approaches. Here, we show that, at least for...

Isotope fractionation due to diffusion and sorption of chlorinated hydrocarbons and its implications for identifying reactive processes in aquifer - aquitard systems

Wanner, Philipp ; Hunkeler, Daniel (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Chlorinated hydrocarbons are anthropogenic contaminants, which are known to be possibly carcinogenic to humans. Although the peak production of chlorinated hydrocarbons in the 1970ties was followed by a dramatic decrease in the subsequent decades, chlorinated hydrocarbons are still frequently detected in aquifer systems demonstrating their long-term persistence. When chlorinated hydrocarbons are...

Action selectors without Floer-Homology

Haug, Carsten ; Schlenk, Felix (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Hamiltonian systems on symplectic manifolds tend to have many periodic orbits. The “actions” of these orbits form an invariant for the Hamiltonian system. The set of actions can be very large, however. To get useful invariants, one selects for each Hamiltonian function just one action value by some minimax procedure: A so-called action selector associates with every compactly supported...
