[1] We present a validation of a three-dimensional magnetohydrodynamic model for the solar corona and the inner heliosphere. We compare the results of the model with long-term satellite data at 1 AU for a 1 year period during solar minimum and another year period of solar maximum. Overall, the model predicts rather well the magnitude of the magnetohydrodynamical variables for solar minimum cond...

Cortaderia (Poaceae; Danthonioideae) is a medium-sized genus of C3 tussock grasses, widespread in the temperate to tropic-alpine regions of South America. It is particularly important in the subalpine and alpine zones of the Andes. We revised the classification of the genus, and recognize 17 species grouped into five informal groups. We describe one new species, Cortaderia echinata H.P.Linder, ...

A synoptic comparison of the liquid noble gas experiments from a technical and methodological point of view, discussing their low energy physics application in the Dark Matter direct investigation, is presented.

Because pulmonary arteries are end arteries, the circulation within the lung once appeared to be simple. However, an increasing amount of information concerning the systemic contribution to this circulation, mainly through bronchopulmonary anastomoses, has made the picture complex. The intricate network that the bronchial vessels establish between the aorta and the pulmonary arteries on the one...
