Viability rates were determined for microbial populations of Escherichia coli and Deinococcus radiodurans under the environmental stresses of low temperature (-35 degrees C), low-pressure conditions (83.3 kPa), and ultraviolet (UV) irradiation (37 W/m(2)). During the stress tests the organisms were suspended in saltwater soil and freshwater soil media, at(More)
In this work optical properties of SiOX ð0 , X , 2Þ layers obtained by plasma enhanced chemical vapor deposition are studied. Infrared spectra and refractive index dependences with the reactant gases flow ratio R are explained for as deposited, aged and thermally treated samples in the R range from 9.17 to 110. Variations are found to be influenced mainly(More)
