The article examines: (i) the reasons of error due to thermoelectric inhomogeneity of electrodes of thermocouples acquired during prolonged use; (ii) the neural network method of error correction based on a generalization of verification results in several temperature fields; (iii) the method of investigating the impact of changing the speed of the conversion characteristic drift of thermocoupl...

The kinetics of phenol oxidation with chlorine dioxide in different solvents (2 methylpropan 1 ol, ethanol, 1,4 dioxane, acetone, acetonitrile, ethyl acetate, dichloromethane, heptane, tetrachloromethane, water) was studied by spectrophotometry. In all solvents indicated, the reaction rate is described by an equation of the second order w = k[PhОН]•[ClO2]. The rate constants were measured (at 1...

От переводчика С разрешения авторов мы перевели первую главу их книги, и один из них (В. В.) смог найти время и просмотреть первые семь страниц перевода. Текст главы оказался весьма непривычным, а потому трудным для перевода, и мы совсем не уверены, что в нём не осталось ошибок. Надеемся, что В. В. сможет со временем просмотреть и исправить оставшуюся часть перевода, после чего можно будет данн...

А number of ribosomal proteins inEscherichia coliundergo posttranslational modifications. Six ribosomal proteins are methylated (S11, L3, L11, L7/L12, L16, and L33), three proteins are acetylated (S5, S18, and L7), and protein S12 is methylthiolated. Extra amino acid residues are added to protein S6. С-terminal amino acid residues are partially removed from protein L31. The functional significa...

The X-ray and magnetometry methods were used to study α-γ transformation mechanisms on heating quenched Fe-22.7 wt.% Ni-0.58 wt.% С alloy. Variation of heating rate within 0.03-80 K/min allowed one to switch from diffusive to non-diffusive mechanism of the α-γ transformation. Heating up primary austenitic single crystal specimen at a rate of less than 1.0-0.5 K/min has led to formation of aggre...
