Autor: Sung-Wook Kim, Min Ku Jeon, Kirak Lee

Publikováno v: Archives of Metallurgy and Materials, Vol vol. 65, Iss No 3, Pp 1051-1055 (2020)

CaO sorbent dissolved in chloride molten salts was investigated to identify its CO2 capture property. Various molten salt systems with different melting points (CaCl2, LiCl, LiCl-CaCl2, and LiCl-KCl) were used to control the operation temperature fro

The Middle and Late Bronze Age, a period roughly spanning the 2(nd) millennium BC (ca. 2000-1200 BC) in the Near East, is frequently referred to as the first 'international age', characterized by intense and far-reaching contacts between different en

Current archaeological paradigm proposes that the first peopling of the Americas does not exceed the Last Glacial Maximum period. In this context, the acceptance of the anthropogenic character of the earliest stone artefacts generally rests on the pr

Neanderthal extinction has been a matter of debate for many years. New discoveries, better chronologies and genomic evidence have done much to clarify some of the issues. This evidence suggests that Neanderthals became extinct around 40,000–37,000

Publikováno v: Jornal Brasileiro de Patologia e Medicina Laboratorial, Vol 40, Iss 2, Pp 63-67 (2004)

Helicobacter pylori is found in the stomach of most patients with duodenal ulcer. Techniques for its diagnosis include histopathology, urease test and urea breath test (UBT) using urea labeled with radioactive (14C) or stable carbon (13C). The object

Our knowledge of the recolonization of north-west Europe at the end of the Last Glacial Maximum depends to a large extent on finds from Gough’s Cave (Somerset, UK). Ultra-high resolution radiocarbon determinations suggest that the cave was occupied
