Complex socio-economic, political and demographic factors have driven the increased conversion of Europe’s semi-natural grasslands to intensive pastures. This trend is particularly strong in some of the most biodiverse regions of the continent, such as Central and Eastern Europe. Intensive grazing is known to decrease species diversity and alter the composition of plant and insect communities. Comparatively little is known, however, about how intensive grazing influences plant functional traits related to pollination and the structure...

Stenosis at the beginning of the internal jugular vein compromise outflow through this blood vessel and can alter geometry of the jugular valve located downstream: the results of numerical modeling of blood flow

Marian Simka
Background and Objective. Currently, pathological jugular valves are thought to be the main cause of altered hemodynamics in the internal jugular veins. The alternative interpretation of flow disturbances in these veins is that nozzle-like strictures in their upper parts, for example caused by enlarged bony processes, are the main source of abnormal outflow. This in silico study was aimed at validation of this hypothesis.Methods. Computational fluid mechanics software, COMSOL multiphysics, was used. For numerical validation...
