Hashimoto, Masaaki, and Noriyuki Yamamoto. Decrease in heart rates by artificial CO2 hot spring bathing is inhibited by 1-adrenoceptor blockade in anesthetized rats. J Appl Physiol 96: 226–232, 2004. First published August 29, 2003; 10.1152/japplphysiol.00812.2003.—To investigate the effects of carbon dioxide (CO2) hot spring baths on physiological functions, head-out immersion of urethane-anes...

Physical and chemical barriers separate individual terrestrial hot springs and their affiliated communities of thermophilic bacteria. However, 16S rRNA gene sequence comparisons suggest that seemingly identical or closely related bacterial species are found in multiple hot springs that are separated by distances that range from a few meters to thousands of kilometers. To investigate whether thi...

The properties of two improved versions of charge-on-spring (COS) polarizable water models (COS/G2 and COS/G3) that explicitly include nonadditive polarization effects are reported. In COS models, the polarization is represented via a self-consistently induced dipole moment consisting of a pair of separated charges. A previous polarizable water model (COS/B2), upon which the improved versions a...

BACKGROUND Carbonated and non-carbonated beverages manufactured based on mineral and spring waters have been present at the Polish market shortly, and their production and sales are regularly growing. The products have become commonly known as flavoured waters. OBJECTIVE The aim of the work was to identify and assess the content of carbohydrates used for sweetening mineral and spring water-ba...

For a microbial ecological analysis, 20 strains of Legionella pneumophila isolated from both unchlorinated Noyu (unattended natural hot spring) samples and chlorinated hot spring bath water samples collected throughout Japan were subjected to a clustering analysis on the basis of a Pulsed-Field Gel Electrophoresis (PFGE) pattern analysis. The PFGE patterns obtained from 19 strains of L. pneumop...

Springs and seeps occur in the spaces around Po Hing Fong Street in the Mid-Levels area, Hong Kong. Most of the springs occur through the drainage weepholes on retaining walls at the street. This paper first examines the geology and history of the springs. The paper then reports the findings from a 1-year comprehensive spring monitoring programme. The temporal variations of flow rate, physioche...

Despite relatively good knowledge of the biogeochemistry of Siberian thermokarst lakes during summer base flow, their seasonal dynamics remains almost unexplored. This work describes the chemical composition of ∼ 130 thermokarst lakes ranging in size from a few m to several km, located in the discontinuous permafrost zone. Lakes were sampled during spring flood, just after the ice break (early ...
