This paper presents a generalized solution to modelling hydraulic erosion using ideas from fluid mechanics. The model is based on the Navier–Stokes equations, which provide the dynamics of velocity and pressure. These equations form the basis for the model to balance erosion and deposition that determine changes in the layers between water and erosion material. The eroded material is captured a...
Environmental psychology research has demonstrated that exposure to mundane natural environments can be psychologically beneficial, and can, for instance, improve individuals' mood and concentration. However, little research has yet examined the psychological benefits of extraordinary, awe-evoking kinds of nature, such as spectacular mountain scenes or impressive waterfalls. In this study, we a...
2014 Through the description of three new series of polar compounds with a cyano or a nitro terminal group we progress in the generalization of the (x, T) binary diagrams dealing with bilayered fluid smectic phases. New arguments are put forward concerning the conspicuousness of the SAd-S A2 transition according to the structure of the SAd phase. For the second time a SA2~ SC2~ S? bilayer seque...
Using high-resolution angle-resolved photoemission spectroscopy we have studied the momentum and photon energy dependence of the anomalous high-energy dispersion, termed waterfalls, between the Fermi level and 1 eV binding energy in several high-T_{c} superconductors. We observe strong changes of the dispersion between different Brillouin zones and a strong dependence on the photon energy aroun...
Isernia La Pineta (south-central Italy, Molise) is one of the most important archaeological localities of the Middle Pleistocene in Western Europe. It is an extensive open-air site with abundant lithic industry and faunal remains distributed across four stratified archaeosurfaces that have been found in two sectors of the excavation (3c, 3a, 3s10 in sect. I; 3a in sect. II). The prehistoric att...
Species of the Asian genus Eotrechus Kirkaldy, 1902 (Hemiptera, Heteroptera, Gerromorpha, Gerridae, Eotrechinae) are atypical water striders because they live on near-vertical rock surfaces waterfalls. The taxonomy is revised and six new species described: E. steineri sp. nov. , kerberos thai konkakinh boukali anderseni Supplementary descriptions apterous female macropterous male fuscus Basu, C...
The headwaters of five large African river basins flow through the Bié Plateau in Angola and still remain faunistically largely unexplored. We investigated fish fauna from the Cuanza and Okavango-Zambezi river systems from central Angola. We reconstructed molecular phylogenies of the most common cichlid species from the region, Tilapia sparrmanii and Serranochromis macrocephalus, using both mit...
We investigate a method called Multiple-Instance learning for learning simple templates that capture the color and spatial properties of classes of natural scene images from a small set of examples. These templates encode a scene class as image patches with color and spatial relations and can be used to classify a variety of natural scenes like elds, waterfalls and mountains among others. Examp...
