Serum samples from 996 dogs in Switzerland were examined for antibodies to Ehrlichia canis and to the agent causing canine granulocytic ehrlichiosis (CGE). Ehrlichiosis, borreliosis, and systemic illness not associated with ticks were suspected in 75, 122, and 157 of these dogs, respectively. The remainder of the serum samples were obtained from clinically healthy dogs which resided north (n = ...

Methanobrevibacter arboriphilus strain DH1 is an autotrophic methanogen that was isolated from the wetwood of methane-emitting trees. This species has been of considerable interest for its unusual oxygen tolerance and has been studied as a model organism for more than four decades. Strain DH1 is closely related to other host-associated Methanobrevibacter species from intestinal tracts of animal...

At least four genes encode the human alkaline phosphatases (ALPs). The genes encoding three of these proteins (intestinal, placental, and placental-like ALPs), are linked on the long arm of chromosome 2, while the fourth gene (encoding liver/bone/kidney ALP) is located on chromosome 1. One of the linked genes, intestinal alkaline phosphatase, has been isolated on two overlapping phage clones an...

Alpine permafrost occurrence in maritime climates has received little attention, despite suggestions that permafrost may occur at lower elevations than in continental climates. To assess the spatial and altitudinal limits of permafrost in the maritime Southern Alps, we developed and tested a catchment-scale distributed permafrost estimate. We used logistic regression to identify the relationshi...

Stalagmite SV1 from Grotta Savi, located at the SE margin of the European Alps (Italy), is the first Alpine speleothem that continuously spans the past c. 17 kyr. Extension rate and dOc record for the Lateglacial probably reflect a combination of temperature and rainfall, with rainfall exerting the dominant effect. Low speleothem calcite dOc values were recorded from c. 14.5 and 12.35 kyr, duri...

The COIN-OR High Performance Parallel Search (CHiPPS) framework is a C++ class library for implementing and parallelizing tree search algorithms. It currently consists of a library of base classes known as the Abstract Library for Parallel Search (ALPS) and two other layers useful for implementing algorithms based on mathematical programming paradigms. Because of its general approach, however, ...

Foreword In this seminar, I would like to briefly illustrate, also using some images, the study I am working on in Cerveno, a small valley town in the Italian Alps. This involves, as is customary in

tion may represent a pathophysiologically important T-cell subpopulation involved in the characteristic progressive loss of hematopoietic stem cells from the bone marrow microenvironment in AA. Related, others have previously shown that T lymphocytes are a potent source of inflammatory and regulatory cytokines, including interleukin 10 (IL-10), reported to be elevated in a subgroup of patients ...

Dieser Text stellt das Projekt “Planning with Virtual Alpine Landscapes and Autonomous Agents” (ALPSIM www page, accessed 2003) vor, welches vom Programm “Habitats and Landscapes of the Alps” des Schweizer Nationalfond finanziert wird. Das Projekt untersucht, inwieweit es möglich ist, Multiagentensimulationen einzusetzen, um landschaftliche Veränderungen in Touristengegenden in den Schweizer Al...

The present-day topography of the European Alps shows evidence of intense glacial reshaping. However, significant questions regarding Alpine landscape evolution during glaciations still persist. In this study, we focus on the Rhône valley (Swiss Alps), and use a numerical model to estimate patterns and magnitudes of glacial erosion. Comparing modeling results on a reconstructed pre-glacial topo...
