Volcanic lakes within calderas should be viewed as high-risk systems, and an intensive lake monitoring must be carried out to evaluate the hazard of potential limnic or phreatic-magmatic eruptions. In Ecuador, two caldera lakes – Lakes Quilotoa and Cuicocha, located in the high Andean region >3000 a.s.l. – have been the focus of these investigations. Both volcanoes are geologically young or his...

voriconazole is the first-line therapy for invasive aspergillosis. nevertheless, mortality remains high due to different factors. although azoles are very active in vitro against aspergillus fumigatus, several studies have reported azole-resistant a. fumigatus isolates in european countries, asia, and the united states. therefore, new approaches are needed. the aim of the present study was to e...

Watersheds have different water compartments (surface, subsurface, and underground) connected by the soil-water interface. In order to be able relate these compartments, monitoring data are necessary, such as case of Ribeirão Concórdia watershed, in Lontras, Santa Catarina (SC). This study aimed evaluate behavior correlation between rainfall-runoff phreatic surface levels with chemical species ...

Raponzolo is a paleo-phreatic cave explored in 2011 the Brenta Dolomites (Trentino, Italy), at remarkable altitude of 2,560 m a.s.l. Differently to all other caves area, it hosts well-cemented fine medium sands granitic-metamorphic composition. The composition suggests sediment source from Adamello and Tonale Unit, separated by one most important tectonic lineaments Alps (Giudicarie Line). fine...

The Ochtiná Aragonite Cave (Western Carpathians) represents an unique natural phenomenon. It originated under particular lithological and hydrogeological conditions of the Karst in which several isolated lenses Paleozoic crystalline limestone (marbles), partly metasomatically altered to ankerite, are enclosed by phyllites. Meteoric water seepage through non-carbonate rocks dissolved caused oxid...
