frontal temperature zones -- model -- numerical experiments -- current velocity -- turbulent diffusion -- heat flow
Аннотация: The main purpose of the work is to investigate the frontal temperature zones using the mathematical model of the oceanic temperature field. The forecast of the frontal temperature zone variability is based on satellite data. The model calculates the temperature under different starting conditions and allows for the mean monthly intensity of solar radiation, components of current velocities, and turbulent diffusion. The input data are the mean monthly current velocities and the radiation heat flows. The model is used to calculate the dynamics of the frontal temperature zones in separate parts of the ocean. Based on the results of numerical experiments presented in the paper we estimated the spatial and temporal ranges of the frontal zone variation affected by the advection of currents, horizontal turbulent heat exchange, and the radiation heat flow in separate parts of the ocean. As examples we consider the basic frontal zones in the Atlantic and the Pacific Oceans. The work also shows possible applications of parametrization of spatial horizontal components of the frontal zones functionally related to the processes of heat advection and diffusion in the absence of exact information about the magnitudes of the current velocities and turbulent mixing.

Triticum aestivum -- Raphanus sativus var. minor -- fluorescence -- heat tolerance -- pigments -- CO2 exchange
Аннотация: The heat tolerance of wheat (Triticum aestivum L.) and radish (Raphanus sativus L. var. minor) cenoses exposed to elevated and damaging air temperatures (35 degreesC for 20 h, 45 degreesC for 7 h) under photoculture conditions at various levels of photosynthetically active radiation (PAR) was assessed by measuring characteristics of the slow induction curve of chlorophyll fluorescence at 682 and 734 nm and the CO2 exchange rate. Irrespective of the illumination level, the exposure of the cenoses to 35 degreesC did not induce irreversible changes in the plant photosynthetic apparatus. The lowest extent of damage to wheat and radish cenoses exposed to 45 degreesC was observed at 150 W/m(2) of PAR, whereas the highest damage of the plants was observed at an illumination level that was close to the compensation point of the cenose photosynthesis (50-70 W/m(2) of PAR at air temperature of 24 degreesC). Viability index proved to be the most sensitive. characteristic, compared to other characteristics, which were determined by measuring the slow phase of fluorescence induction at 682 and 734 nm. In the cenoses studied, the pattern of changes in the viability index in response to a stress factor was close to the changes in the photosynthetic rate.

Аннотация: The previously undescribed dynamics of the heat shock protein HSP70 and subsequent lipid peroxidation products have been assessed alongside lactate dehydrogenase activity for Gammarus lacustris Sars, an amphipod species from the saltwater Lake Shira (Republic of Khakassia). Individuals were exposed to a gradual temperature increase of 1 degrees C/hour (total exposure duration of 26 hours) starting from the mean annual temperature of their habitat (7 degrees C) up to 33 degrees C. A complex of biochemical reactions occurred when saltwater G. lactustris was exposed to the gradual changes in temperature. This was characterized by a decrease in lactate dehydrogenase activity and the launching of lipid peroxidation. The HSP70 level did not change significantly during the entire experiment. In agreement with the concept of oxygen-limited thermal tolerance, an accumulation of the most toxic lipid peroxides (triene conjugates and Schiff bases) in phospholipids occurred at the same time and temperature as the accumulation of lactate. The main criterion overriding the temperature threshold was, therefore, the transition to anaerobiosis, confirmed by the elevated lactate levels as observed in our previous associated study, and by the development of cellular stress, which was expressed by an accumulation of lipid peroxidation products. An earlier hypothesis, based on freshwater individuals of the same species, has been confirmed whereby the increased thermotolerance of G. lacustris from the saltwater lake was caused by differences in energy metabolism and energy supply of nonspecific cellular stress-response mechanisms. With the development of global climate change, these reactions could be advantageous for saltwater G. lacustris. The studied biochemical reactions can be used as biomarkers for the stress status of aquatic organisms when their habitat temperature changes.

Аннотация: An approach to searching for extraterrestrial life on the base of "autotroph" concept of the origin of life is presented in the paper, According to this concept the origin of life took place in three stages. The first stage was developed inside the global geochemical cycle in which the turnover of different chemical transformations was implemented by solar radiation and/or heat energy of bowels of the Earth. At the second stage, after the autocatalytic systems have emerged these systems evolved as a result of "natural selection" by autocatalysis parameters up to emergence of special inheritance systems that drastically improved the autocatalysis parameters. The best in terms of autocatalysis parameters were the autocatalysis systems based on phase-separated particles where complex structures can form not only on the basis of covalent interactions. Such autocatalysis systems can emerge only in liquid in a certain range of temperatures and pressures. At this stage the geochemical cycle complicated involving new substances. At the third stage the evolution involved improvement of inheritance systems resulting in formation of the modern type of genetic apparatus. This concept formed the basis to consider approaches to experimental modeling of major aspects of the origin of life and to outlining some general features of life that can extend the sensitive horizon of searching for extraterrestrial life.

Аннотация: Any comprehensive evaluation of Life Support Systems (LSS) for space applications has to be conducted taking into account not only mass of LSS components but also all relevant equipment and storage: spare parts, additional mass of space ship walls, power supply and heat rejection systems. In this paper different combinations of hybrid LSS (HLSS) components were evaluated. Three variants of power supply were under consideration - solar arrays, direct solar light transmission to plants, and nuclear power. The software based on simplex approach was used for optimizing LSS configuration with respect to its mass. It was shown that there are several LSS configuration, which are optimal for different time intervals. Optimal configurations of physical-chemical (P/C), biological and hybrid LSS for three types of power supply are presented. (C) 2000 COSPAR. Published by Elsevier Science Ltd.

Аннотация: The paper describes the production and investigation of flexible films made of high-purity polyhydroxyalkanoates (PHAs) - polyhydroxybutyrate [poly-(3HB)] and poly-3-hydroxybutyrate-co-poly-3-hydroxyvalerate [poly(3Hl3-co-3HV)], containing 4-30 mol % hydroxyvalerate. Poly(3HB-co-3HV) films have a more porous structure than poly-(3HB) films, which are more compact, but their surface properties, such as wettability and surface and interface energies, are the same. Sterilisation of the PHA films by conventional methods (heat treatment and gamma-irradiation) did not impair their strength. Cells cultured on PHA films exhibited high levels of cell adhesion. Cell morphology, protein synthesis and DNA synthesis were estimated by extent of H-3-thymidine incorporation into the animal cell cultures of various origins (fibroblasts, endothelium cells, and isolated hepatocytes) in direct contact with PHAs. The investigation showed that this material can be used to make matrices for in vitro proliferous cells. The investigated properties of poly-(3HB) and poly(3HB-co-3HV) films proved to be fundamentally similar. (C) 2004 Kluwer Academic Publishers.

Аннотация: Laboratory experiments were conducted in a hermetically sealed growth chamber with two soil samples obtained from the arctic tundra zone with different levels of moisture. Samples were maintained at a growing season typical of the region from which they were taken, and for the sample with a high level of moisture it was made twice: with the temperature in accord with natural conditions and one increased by 2 degrees C. It has been shown that heating of the overmoistened tundra soil by 2 degrees C can increased the average carbon dioxide emissions by almost two times (from 75 to 100-150 mg m(-2) h(-1)). Upon the application of heat, no significant increase in methane emission was observed.

Аннотация: A composite of alumina nanofibers (ANF) and modified detonation nanodiamonds (MDND) was produced by mixing aqueous suspensions of the components in a weight ratio of 5 : 1 with subsequent incubation of the mixture for 15 min at 32 degrees C. It was assumed that the formation of the composite is ensured by the difference of the zeta potentials of the components, which is negative for MDND and positive for ANF. Vacuum filtration of the mixture through a fluoroplastic filter (pore diameter 0.6 mu m) formed disks 40 mm in diameter, which were then heat-treated at 300 degrees C to impart structural stability to the composite. Scanning electron microscopy detected that the obtained composite has a network structure, in which MDND particles are distributed over the surface of ANF. It was determined that the MDND particles incorporated in the composite catalyze the phenol-4-aminoantipyrine-H2O2 oxidative azo coupling reaction to form a colored product (quinoneimine). The applicability of the composite to repeated phenol detection in aqueous samples was demonstrated.

Аннотация: Based on own and literature data, the review of existing approaches to justification of concepts of selecting contemporary light sources for plant cultivation in greenhouse conditions is presented. The work covers comparative experimental data on productivity of lettuce leaves formed under radiation of light-emitting diode emitters with a phytospectrum and white light. A high-pressure sodium lamp was taken as a control source. Lack of valid differences between this data is found out. The article discusses data of literature where effect of heat radiation on plant productivity was discovered by means of light sources of different generations (metal halide lamps, xenon lamps), which is an additional factor apart from visible radiation spectrum which is capable of influencing photobiological efficiency of lamps. On the basis of data of literature, the role of background natural solar light in greenhouses which can negatively affect spectral efficiency of artificial light sources used for supplementary lighting of plants is discussed. A set of methodological factors influencing spectral efficiency of radiation for plant productivity as well as aspects of selection of lamps for cultivation of plants in greenhouse conditions for different latitudes are reviewed and scientifically validated. A controversy in selection of PAR chromaticity of light sources for plant cultivation is demonstrated. The concept of selecting 2 a light source for plant cultivation based on availability of specific response of plant groups to PAR chromaticity is proposed as the most objective for practical application. © 2019, LLC Editorial of Journal "Light Technik".

Аннотация: Abstract: The results of a hydrochemical analysis of the consequences of an accidental fuel release in the Norilsk–Pyasino water system are presented. The pollution of watercourses in the catchment of Lake Pyasino (a nameless (Nadezhdinsky) creek, the Daldykan River, and the Ambarnaya River) with oil products, phenols, easily oxidizable and hard to oxidize organic matter (COD, PO, and BOD5), suspended solids, inorganic salts, and heavy metals at concentrations exceeding the background levels and MPC for fishery water bodies, as well as a temperature rise in waters of the nameless creek near Norilsk Heat and Power Plant 3 (CHPP-3), have been revealed. The contamination of the surface water decreases downstream in ascending order: nameless creek–Daldykan River–Ambarnaya River. The occurrence of oil products, phenols, and organic substances in the surface waters 2 months after the fuel spill is obviously due to their diffusion from the river bottom sediments, which accumulated a considerable quantity of heavy fractions of diesel fuel after the accident. Increased concentrations of Ca, Cu, Zn, Mn, Co, and Ni in the waters of the studied tributaries of Lake Pyasino are not directly related to the accident; they result from the general technogenic pollution of the territory and the increased geochemical background for these elements. Water contamination with oil products and phenols in the studied areas of Lake Pyasino (its central and northern parts) and the Pyasino River has not been detected. However, Pb concentrations exceed the MPC and Cd is recorded in the water, which is probably due to pollutants that accumulated in previous years. © 2021, Pleiades Publishing, Ltd.

Water contamination with oil products and phenols in the studied areas of Lake Pyasino (its central and northern parts) and the Pyasino River has not been detected. However, Pb concentrations exceed the MPC and Cd is recorded in the water, which is probably due to pollutants that accumulated in previous years.

Role of Hsp90 and ATP in modulating apyrase activity and firefly luciferase kinetics / M. A. Kirillova [et al.] // Int. J. Biol. Macromol. - 2019. - Vol. 131. - P691-696, DOI 10.1016/j.ijbiomac.2019.03.110 . - ISSN 0141-8130

Аннотация: The present manuscript describes a novel bioassay consisting of apyrase and heat shock protein 90 (Hsp90) without additional co-chaperone supplementation; intended for high-throughput screening of anti-cancer drugs and prognosis of stress. In this regard, Hsp90 and adenosine 5?-triphosphate (ATP) mediated firefly luciferase (FLuc) kinetics was investigated using apyrase and FLuc as client proteins. Bioluminescent assay containing Hsp90, ATP, and apyrase led to complete loss of luminescence at 50 °C which indicates the protective role of Hsp90 against thermal denaturation. Similarly, the assay sample comprising Hsp90, ATP, and FLuc showed 2 fold increments in luminescence than their counterparts. Introduction of bovine serum albumin (BSA) to the pre-incubated assay mixture led to an initial rise in the luminescence (28%) in comparison to the sample containing Hsp90, ATP and FLuc. Therefore, FLuc based HTS assays are not suitable for clinical samples which may contain stabilizing agents. However, thermally denatured FLuc and apyrase could not regain their active conformation even when Hsp90 and ATP were introduced in the assay system. This observation justifies the role of Hsp90 to be protective rather than a reparation agent when acts without co-chaperones. © 2019

Cold and hot extracts -- culture liquid -- enzymatic system -- hispidin -- luminous fungi -- substrate of luminescent reaction
Аннотация: The luminescent response of the enzymatic system of Armillaria borealis on the cold and hot extracts from cell-free culture liquids of Inonotus obliquus, Pholiota sp. and A. borealis was examined. The greatest influence on the light emission produced by the luminescent system of A. borealis was provided by the temperature at which the probes were prepared for assay. Boiling a culture liquid on water bath for a few minutes promoted a multifold increase in the luminescence. The results of luminescence assay suggest that the substance involved in the bioluminescent reaction in higher fungi is presented in culture liquids and mycelia in two forms. In one form, it is ready to interact with the enzymatic system and in the second form, it becomes accessible for the reaction after heat treatment. The pool of thermoactivated substance was found to be much large than the amount of the ready accessible one. We suggest that predecessors of hispidin, which is fungal luciferin precursor, are responsible for this phenomenon. They are not involved in bioluminescence at their original state and are converted into the substrate under the influence of high temperature. © 2019, © 2019 The Author(s).

Production of a Composite Based on Alumina Nanofibers and Detonation Nanodiamonds for Creating Phenol Indication Systems / N. O. Ronzhin, E. D. Posokhina, E. V. Mikhlina [et al.] // Dokl. Chem. - 2019. - Vol. 489, Is. 1. - P267-271, DOI 10.1134/S001250081911003X . - ISSN 0012-5008
Аннотация: Abstract: A composite of alumina nanofibers (ANF) and modified detonation nanodiamonds (MDND) was produced by mixing aqueous suspensions of the components in a weight ratio of 5 : 1 with subsequent incubation of the mixture for 15 min at 32°C. It was assumed that the formation of the composite is ensured by the difference of the zeta potentials of the components, which is negative for MDND and positive for ANF. Vacuum filtration of the mixture through a fluoroplastic filter (pore diameter 0.6 ?m) formed disks 40 mm in diameter, which were then heat-treated at 300°C to impart structural stability to the composite. Scanning electron microscopy detected that the obtained composite has a network structure, in which MDND particles are distributed over the surface of ANF. It was determined that the MDND particles incorporated in the composite catalyze the phenol–4-aminoantipyrine–H2O2 oxidative azo coupling reaction to form a colored product (quinoneimine). The applicability of the composite to repeated phenol detection in aqueous samples was demonstrated. © 2019, Pleiades Publishing, Ltd.

Аннотация: Based on own and literature data, the review of existing approaches to justification of concepts of selecting contemporary light sources for plant cultivation in greenhouse conditions is presented. The work covers comparative experimental data on productivity of lettuce leaves formed under radiation of light-emitting diode emitters with a phytospectrum and white light. A high-pressure sodium lamp was taken as a control source. Lack of valid differences between this data is found out. The article discusses data of literature where effect of heat radiation on plant productivity was discovered by means of light sources of different generations (metal halide lamps, xenon lamps), which is an additional factor apart from visible radiation spectrum which is capable of influencing photobiological efficiency of lamps. On the basis of data of literature, the role of background natural solar light in greenhouses which can negatively affect spectral efficiency of artificial light sources used for supplementary lighting of plants is discussed. A set of methodological factors influencing spectral efficiency of radiation for plant productivity as well as aspects of selection of lamps for cultivation of plants in greenhouse conditions for different latitudes are reviewed and scientifically validated. A controversy in selection of PAR chromaticity of light sources for plant cultivation is demonstrated. The concept of selecting a light source for plant cultivation based on availability of specific response of plant groups to PAR chromaticity is proposed as the most objective for practical application.

Аннотация: Contents of fatty acids in filets of unfrozen (control), boiled, fried, roasted and boiled in a small amount of water humpback salmon, collected from a wholesale market in Krasnoyarsk city (Siberia, Russia) were analyzed. Special attention was paid to essential polyunsaturated fatty acids of ?3 family: eicosapentaenoic, 20:5?3 (EPA) and docosahexaenoic, 22:6?3 (DHA). Heat treatment in general did not decrease content of EPA and DHA in humpback, except a modest reduction during frying. Cooked humpback appeared to be the valuable source of essential ?3 PUFAs, namely EPA and DHA. It was hypothesized that the absence of significant reduction of PUFAs' contents in red flesh of fishes of Salmonidae family during heat treatment may be due to a high level of natural antioxidants which formed in the course of evolution as adaptation to their ecological niche.

Аннотация: Frozen samples of common fish species, sea trout (Salmo trutta), from Norway and Siberia, herring (Clupea harengus pallasi), rock sole (Lepidopsetta bilineata) and cod (Gadus morhua maris-albi), collected from a wholesale market in Krasnoyarsk city (Siberia, Russia) were analyzed. Special attention was paid to long-chain essential polyunsaturated fatty acids: eicosapentaenoic, 20:5?3 (EPA) and docosahexaenoic, 22:6?3 (DHA). Heat-treatment (cooking and frying) did not in general significantly decrease the contents of EPA and DHA compared to raw fish species, except for a modest reduction in Norwegian trout during frying. Boiled trout appeared to be a more valuable fish dish for obtaining the officially recommended appropriate daily intake of EPA + DHA for humans. Herring and sole had intermediate values, while boiled cod had a comparatively low value. В© 2006 Elsevier Ltd. All rights reserved.

Tolerance of wheat and lettuce plants grown on human mineralized waste to high temperature stress / S. A. Ushakova [et al.] // Advances in Space Research. - 2013. - Vol. 51, Is. 11. - P2075-2083, DOI 10.1016/j.asr.2013.01.017 . - ISSN 0273-1177

Аннотация: The main objective of a life support system for space missions is to supply a crew with food, water and oxygen, and to eliminate their wastes. The ultimate goal is to achieve the highest degree of closure of the system using controlled processes offering a high level of reliability and flexibility. Enhancement of closure of a biological life support system (BLSS) that includes plants relies on increased regeneration of plant waste, and utilization of solid and liquid human wastes. Clearly, the robustness of a BLSS subjected to stress will be substantially determined by the robustness of the plant components of the phototrophic unit. The aim of the present work was to estimate the heat resistance of two plants (wheat and lettuce) grown on human wastes. Human exometabolites mineralized by hydrogen peroxide in an electromagnetic field were used to make a nutrient solution for the plants. We looked for a possible increase in the heat tolerance of the wheat plants using changes in photosynthetically active radiation (PAR) intensity during heat stress. At age 15 days, plants were subjected to a rise in air temperature (from 23 В± 1 В°C to 44 В± 1 В°) under different PAR intensities for 4 h. The status of the photosynthetic apparatus of the plants was assessed by external 2 gas exchange and fluorescence measurements. The increased irradiance of the plants during the high temperature period demonstrated its protective action for both the photosynthetic apparatus of the leaves and subsequent plant growth and development. The productivity of the plants subjected to temperature changes at 250 W m-2 of PAR did not differ from that of controls, whereas the productivity of the plants subjected to the same heat stress but in darkness was halved.
