Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Paleotemperature models of the Phanerozoic foci of hydrocarbon generation for wells belonging to the Severo-Kalinov and Kalinov fields in Tomsk region [PDF]

open access: yesНефтегазовая геология: Теория и практика
This paper suggests a new method of coupled paleotemperature modelling of the Nyurol Paleozoic basin and the blanketing younger Mesozoic-Cenozoic basin. Modelling show that under the geological and geophysical circumstances of the Severo-Kalinov and the ...
