Respiratory responses to increased skin temperatures were recorded in anesthetized cerebrate and in unanesthetized decerebrate cats. All were vagotomized, glomectomized, and paralyzed. Core body temperature and end-tidal Pco2 were kept constant with servoncontrollers. Stimulation of cutaneous nociceptors by heating the skin to 46 degrees C caused respiration to increase in both cerebrate and decerebrate cats. An even larger facilitation of respiration occurred when the skin temperature was elevated to 51 degrees C. However, respiration did not increase in either group of cats when the skin was heated to 41 degrees C to activate cutaneous warm receptors. The phenomenon of sensitization of nociceptors was observed. Spinal transection prevented all the respiratory responses to cutaneous heating. We conclude that noxious, but not nonnoxious, increases in skin temperature cause increases in respiratory output.

The effect on airway conductance (Gaw) and functional residual capacity (FRC) of stimulation of cold receptors in facial skin was studied in 12 healthy young subjects, with a body plethysmograph. Mean Gaw decreased significantly, from 0.44 to 0.38 liter s−1 cm−1 H2O, in 10 subjects. FRC was only slightly affected, probably because the experiment was too brief to allow air-trapping. It is concluded that the Gaw decrease during exposure to cold results from bronchoconstriction due to (a) stimulation of trigeminal nerve cold receptors and to (b) pharyngeal and glottal airway resistance increase resulting from frequent involuntary 'dry' swallowing.

The results of a pilot application of a chemical composition for enhanced oil recovery developed at the IPC SB RAS are presented. The EOR-composition was tested in 2014 at the Permian-Carboniferous heavy oil deposit at the Usinskoye oil field. It is very effective for an increase in oil production rate and decrease in water cuttings of well production. In terms of the additionally produced oil, the resulting effect is up to 800 tons per well and its duration is up to 6 months. The application of technologies of low-productivity-well stimulation using the oil-displacing IKhNPRO system with controlled viscosity and alkalinity is thought to be promising. This composition is proposed for the cold’ stimulation of high-viscosity oil production as an alternative to thermal methods.
