Average duration of a thermal winter in Hornsund has been determined for 216 days. Average soil temperature at depth of 5 cm in winter is equal —9.8°C. During a spring that lasts 35 days only, soil temperatures at depth of 5 cm indicate distribution nearest to a normal one. Soil temperature distribution in winter substantially differs from the one in spring.
A series of nanocomposite graphene/CoFe2O4 and graphene/NiFe2O4 hybrid materials was synthesized via facile, one-pot solvothermal route. The materials were obtained using two pressure methods: synthesis in the autoclave and synthesis in the microwave solvothermal reactor. The use of a microwave reactor enabled to significantly shorten the synthesis time up to 15 min. All the syntheses were carried out in a solution of ethanol. The effect of processing conditions and composite composition on the physicochemical properties and electric conductivity was studied. The specific surface area, density, morphology, phase composition, thermal properties and electric conductivity of the obtained composites were investigated. The results of studies of composites obtained in an autoclave and in a microwave reactor were compared.
In the collection of articles by Peter Strawson published in his Analysis and metaphysics the author defines his meta-philosophical position by offering two analogies, relating respectively to philosophy conceived as therapy and to philosophy construed as a grammar of thought. These analogies, if they are viewed in a perspective invoked by reflections on ‘the human condition’ – admittedly, a style of investigation fairly remote form analytic research – open several interesting questions and raise puzzling uncertainties. If we follow some implications of these queries, the general position of Strawson in contemporary philosophy becomes more convincing; it fits quite comfortably in the ‘mainstream philosophy’, and highlights some leading topics in the eternal philosophical agenda.
