Аннотация: It has been first shown experimentally that stochastical characteristics of exchange fluctuation in amorphous alloy CoP (P = 9-12 at.%) are mainly caused by compositional (chemical) disorder, i.e. by the degree of supersaturation of solid solution but not by the type of structural state.

Аннотация: The effect of different cultivation parameters on the specific activities of soluble and membrane-bound hydrogenases was studied in Alcaligenes eutrophus Z-1 cells. These activities were shown to be dependent primarily on the availability of electrons from the substrate used. Changes in cultivation temperature and oxygen concentration versus the optimal values as well as addition of low amounts of carbon monoxide to the gas phase exerted a lesser effect on the specific hydrogenase activities. Autotrophic and heterotrophic methods were developed for growing A. eutrophus Z-1 cells with a high hydrogenase activity.

Аннотация: A green flavoprotein (GFP) was isolated and purified to homogeneity from Photobacterium leiognathi, strain 208. GFP is a homodimer of molecular weight 54,000 and contains two molecules of an unusual flavin per molecule of protein. Various biochemical characteristics including isoelectric point, trypsin and chymotrypsin degradation, SDS and temperature influence on subunit dissociation and the dissociation of the flavin chromophore, were investigated. The sequence of 23 N-terminal amino acids was determined and found to be concurrent with the N-terminal amino acid sequence encoded by the lux G(N) gene of P. leiognathi. This fact suggests that GFP is a structural component of the Photobacterium luminescence system.

Ключевые слова (''Своб.индексиров.''): photoproteins--obelin--activation energy--thermoinactivation--thermostability
Аннотация: The temperature dependence of bioluminescent activity of the Ca2+-activated photoprotein obelin from the hydroid polyp Obelia longissima and thermoinactivation of this protein at different concentrations of (NH4)2SO4 have been studied. The maximal intensity of luminescence of obelin was observed at 4-15-degrees-C. The activity of the photoprotein is completely stable to storage for 3 days at room temperature. Increasing the temperature to 40-degrees-C resulted in a 25-30% loss of enzyme activity in 1 h. The presence of ammonium sulfate during heating stabilizes the activity of obelin. Two breaks, at 11 +/- 3-degrees-C and 47 +/- 3-degrees-C, are observed in the Arrhenius plot of the first-order rate constant of the luminescence decay. The bioluminescent curves of obelin are biphasic in the temperature range 10-40-degrees-C. It is assumed that obelin may exist in two kinetically distinct conformers (active and inactive) whose ratio is temperature dependent.

Аннотация: Effect of condensed monolayer of stearic acid on temperature of surface water film was investigated using an experimental cell for various ratios of water and air temperatures. When the temperature of air was higher than that of water (positive convective flux), spreading of the acid monolayer provided increasing of temperature of the surface water film. Under inverse relation between the air and the water temperatures (negative convective flux) the temperature of the surface water film was decreased by the acid monolayer. The effect observed could be explained by stabilization of the surface water layer in presence of the acid monolayer. This results in suppression of the convective exchange between the surface film and the bulk of the water.

Заглавие : The influence of a monolayer of an aliphatic acid on temperature oscillation in the surface layer of water
Место публикации : Izvestiya - Atmospheric and Ocean Physics. - 1996. - Vol. 32, Is. 3. - С. 378-380. - ISSN 00014338 (ISSN)
Ключевые слова (''Своб.индексиров.''): aliphatic acid--surface films--temperature--thermal spots
Аннотация: The influence of a monolayer of a palmitic acid on amplitude-frequency characteristics of temperature oscillations caused by thermal spots of a surface film was experimentally determined in a Langmuir tank. An analysis of the power spectra showed that the temperature oscillations were multimodal. In addition, no consistant differences between the spectrum for a pure surface and the spectrum for a surface covered by an acid monolayer were found. A roughened gain-frequency factor was found that is equal to the ratio of the average period between the thermal spots to the dispersion of the time series of temperature oscillations. The factor significantly differed over a wide range of temperatures for a pure surface and for a surface covered with the monolayer. The experimental results do not confirm the existence of a leading frequency in the temperature oscillations of a cold surface film due to an appearance of thermal spots.

Заглавие : The role of population density in gamogenesis induction in moina macrocopa (Cladocera: Crustaceae)
Место публикации : Zhurnal Obshchei Biologii. - 1996. - Vol. 57, Is. 3. - С. 366-367. - ISSN 00444596 (ISSN)
Аннотация: Combined influence of population density, temperature and photoperiod on the gamogenesis of individual females of M. macrocopa was investigated. In all experiments the influence of population density was associated with the direct effect of "swarm water". The photoperiod in its broad natural range also influences gamogenesis induction. The increase in temperature above optimum but lower than lethal level sharply decreases the efficiency of gamogenesis. In this case stimulation of gamogenesis is possible by combined effect of poor feeding and high population density. If temperature and photoperiod are optimum for partenogenetic population the change of reproduction mode in lowdensity population of M. macrocopa is determined by poor feeding while in high-density populations density itself is more important. However the increase in food concentration descreases the efficiency of "swarm water" on the gamogenesis induction. According to the hypothesis of nondirect influence of population density an individual decreases its filtarion rate (and starves) under "swarm water" condition.

Заглавие : Photosynthetic apparatus of cucumber and pea plants grown under red light with discrete or continuous spectra

Ключевые слова (''Своб.индексиров.''): and thermoinduced changes in fluorescence yield--cucumis sativum--photo--photophosphorylation--pigments--pisum sativum
Аннотация: The effect of light sources with discrete or continuous spectra of red light (50 W/m2, 600-700 nm) on the structural and functional characteristics of chloroplasts were studied in leaves of cucumber (Cucumis sativum L.) plants, which die under strong red light, and pea (Pisum sativum L.) plants, which tolerate red light under the same conditions. Leaf condition was assessed by measuring thermo-and photoinduced changes in the chlorophyll fluorescence yield and the photochemical and photophosphorylating activities of the chloroplasts. Different responses of the pigment apparatus of pea and cucumber plants to red light with continuous or line spectra were revealed. Pea plants responded to discrete-spectrum light by changing P700 content, the ratio of antenna chlorophyll to P700, and the position of the low-temperature peak of the temperature-induced chlorophyll fluorescence yield. In cucumber plants, disturbances in the energy transfer from the short-wavelength pigments to chlorophyll a were observed. In both plants, the effects of line spectrum light on the pigment apparatus were reversible; the ratio of cyclic to noncyclic photophosphorylation, photosynthetic control, and the extent of the coupling of photosynthetic electron transport to photophosphorylation did not change compared to the control light. The need for examining the line spectra of light sources for growing plants under moderate intensities of artificial light (about 50 W/m2 of photosynthetically active radiation) is discussed.

Ключевые слова (''Своб.индексиров.''): bacterial luciferase--temperature--activation energy
Аннотация: Effects of temperature on bioluminescent patterns of luciferases from luminescent bacteria Vibrio harveyi, Vibrio fischeri, Photobacterium leiognathi, and Photobacterium phosphoreum were studied. The highest luminescence level was observed at 15-25 degrees C for the luciferase from P. phosphoreum, at 20-30 degrees C for the V. fischeri and P. leiognathi enzymes, and at 30-37 degrees C for the enzyme from V. harveyi. All the luciferases were significantly stabilized at increased salt concentrations, at low pH values, or in the presence of dithiothreitol (DTT) and EDTA. The addition of DTT and EDTA affected the reversible stage of enzyme inactivation, while salts reduced the rate of the irreversible stage. A peak corresponding to aggregated protein was detected by gel chromatography of irreversibly inactivated luciferase. Activation energies were calculated for each luciferase in bioluminescent reactions with decanal, dodecanal, tetradecanal, and without aldehydes. The activation energy of the reaction with tetradecanal was much lower than those with the other aldehydes. The temperature dependence of the lifetime of the long-lived reaction intermediate showed that in the 10-30 degrees C interval all the luciferases, except for the enzyme from V. harveyi, have only one active form.
