• I will use the usual Ulam-Harris labelling notation for GW trees. Namely the initial ancestor is labelled ∅. An individual u = (u1, ..., un) is understood to be the un-th descendend of .... of u1-th descendent of ∅. Such an individual has the property that |u| = n meaning that it belongs to the n-th generation. We say that u < v if individual v is a descendent of u and one may concatenate lab...

Abstract The field of (U-Th)/He geochronology and thermochronology has grown enormously over the past ∼25 years. tool is applicable across much geologic time, new chronometers are under continuous development, method used in a diverse array studies. Consequently, technique rapidly expanding user base, labs being established worldwide. This presents both opportunities challenges. Currently there...

A new water-soluble embedding agent, tr ial p roduc t CIBA X 133/20971 has recently been in t roduced for selected electron microscopic investigations (1). D u r c u p a n subsequently proved to be miscible wi th the water-insoluble epoxy resin Araldi te 2 which is commonly used for tissue embedding (2). In this way, an imal tissues can be embedded in Araldi te wi thout being b rough t into con...

We present the sensitivity of Theia experiment to low-energy geo- and reactor antineutrinos. For this study, we consider one possible proposed designs, a 17.8-ktonne fiducial volume Theia-25 detector filled with water-based liquid scintillator placed at Sanford Underground Research Facility (SURF). demonstrate Theia's measure antineutrinos via Inverse-Beta Decay interactions after year data tak...

The Miño River is a good example of bedrock rivers, where sediment geochemistry scarcely studied. Its urban reach when passing through the city Ourense gathers some characteristics that provide interest to its sediments, like scarcity fine sediments accumulation and impact several human activities. Sediments trapped by potholes other rock cavities were considered. In order evaluate society-natu...
