Life at high temperatures.
Water environments with temperatures up to and above boiling are commonly found in association with geothermal activity. At temperatures above 60 degrees C, only bacteria are found. Bacteria with temperature optima over the range 65 degrees to 105 degrees C have been obtained in pure culture and are the object of many research projects. The upper temperature limit for life in liquid water has n...
متن کاملSample environment at low temperatures
2014 A review of low temperature techniques as applied to neutron scattering studies is presented. Methods of temperature measurements especially carbon thermometry are discussed. Problems of heat transfer are treated in detail for different kind of samples and some solutions are proposed. Revue Phys. Appl. 19 (1984) 677-683 SEPTEMBRE 1984, The number of neutron scattering studies at temperatur...
متن کاملReset Noise at Low Temperatures
This paper presents results of the measurement and modelling of reset noise in charge-detection circuits of detector array multiplexers at low temperatures. To explain the temperature dependence of reset noise, it is proposed to take into account the source of noise associated with emission of electrons from interface states under the gate of reset transistor. It was found that at very low temp...
متن کاملMicrobial lipolysis at low temperatures.
It was found that lipase production during the growth of Pseudomonas fluorescens was not a function of the total number of bacteria. The optimal temperatures for bacterial growth and lipase production were determined as 20 and 8 degrees C, respectively. The lipolytic activity was studied in emulsions of olive oil at temperatures ranging from +8 to -30 degrees C. After an initially rapid lipolys...
متن کاملPhotodynamic Hemolysis at Low Temperatures
It is shown that photodynamic hemolysis may occur at -79 degrees C. if the erythrocytes are suspended in a solution containing 70 per cent glycerol which prevents hemolysis by freezing; but that there is no hemolysis under the same conditions at -210 degrees C. At the higher temperature the viscosity of the solution is still low enough to permit appreciable movement of molecules, whereas at the...
