Аннотация: The method of atom-atom potentials has been used to study the glutamyl dipeptide in ionized (glu-) and non-ionized (glu) states. A calculation has been made with a computer of the conformational maps and the statistical sums of glu and glu-. It was found that on transition of glu > glu- fall in the energy exceeds the free energy of initiation of the helix with an increased probability of the helical state of the molecule of glu-. From this it is concluded that glu- may in certain conditions be the embryo of the helix on self-organization of protein. В© 1975.

Аннотация: This work describes avenues to use satellite information to analyse dynamic processes in aquatic ecosystems. Information for this analysis, was retrieved from AVHRR satellite sensor data. This information consisteds of time series of images of radiation temperature and turbidity. We expect this information will be of great value in analysing inland water bodies. Methods to process satellite information using original software and data processing techniques are proposed. For the investigation of the process and analyses of satellite information Shira Lake (Khakasia, Siberia) was used as a case study. To study the variability of the surface temperature and turbidity of the Lake in summer, the satellite and ground-truth data of the lake was applied. This study represents the first evaluation of the dynamic processes for Lake Shira based on satellite, ground-truth and modelling data. We developed algorithms and software to process satellite images to enable the reconstruction of time dependence of temperature and spectral reflectance of water bodies in the visible range, and to make computer-animated films visualising the spatial and temporal dynamics of the study parameters. The analyses of morphometric, meteorological and hydrological characteristics of Lake Shira have provided a realistic opportunity for processing the satellite information and to develop numerical models of variability of the hydrological regime of the lake. The results obtained demonstrate the feasibility of systematically retrieving the spatial information from the satellite data on the dynamics of the surface water temperature and of the suspended matter in the lake.

Аннотация: Deep insight into types of vegetation variability provided by AVHRR space scanner images of vegetation index spatial distribution helps reveal impact of land surface changes on environment. The Institute of Computational Modeling SB RAS has developed nonparametric algorithms of automatic to classify and recognize patterns of these images which helped to reveal: (1) major variability types (generally connected); (2) areas belonging to small classes, which can be used to reveal deviations from 'normal' (e.g., forest fires, etc.); (3) deviation from a certain type of dynamics indicative of changes in condition of plants, which can be used to diagnose pathology at early stages; (4) impact of economical activities on vegetation in Norilsk area. The authors provide biological interpretation of the satellite data. Computer-animated dynamics and color maps are presented. Nonparametric algorithms of an automatic classification and pattern recognition were provided by the Institute of Computational Modeling SB RAS. (C) 2000 COSPAR. Published by Elsevier Science Ltd.

Аннотация: MELiSSA is a microorganism based artificial ecosystem conceived as a tool for understanding the behavior of ecosystems and developing the technology for future Manned Space Missions. MELiSSA is composed of four compartments colonized by the microorganisms required by the function of this ecosystem : breakdown of waste produced by men, regeneration of atmosphere and biosynthesis of edible biomass. This paper reports the mass balance description of a Biological Life Support System composed of the MELiSSA loop and of a Higher Plant Compartment working in parallel with the photosynthetic Spirulina compartment producing edible biomass. The recycling efficiencies of the system are determined and compared for various working conditions of the MELiSSA loop with or without the HPC.

Bioluminescence of bacteria: a rhythmic process / L. Y. Berzhanzkaya, I. I. Gitel'zon, A. M. Fish // BIOPHYSICS. - 1973. - Vol. 18, Is. 2. - P293-301 . - ISSN 0006-3509

Аннотация: New results obtained in the detection of rhythms in the low frequency range in the light signal of a small number of photo bacteria are reported. The luminescence of a small number of bacteria was recorded with an apparatus the sensitivity of which was 12 quanta/pulse. To check the possible rhythms in the luminescence of the bacteria, correlation analysis was made of the interpulse intervals of the detection of the signal with a computer. This revealed a definite rhythm in the bacterial luminescence the fundamental frequency of which lies in the region 8 c/s. Profound modulation of a bioluminescent signal at this and multiple frequencies was demonstrated. The harmonic components found in the spectrum of the signal refute the existing view of the continuous character of bacterial luminescence.

Аннотация: The process of biotic turnover in a closed ecological system (CES) with an external energy flow was analyzed by mathematical modeling of the biotic cycle formation. The formation of hierarchical structure in model CESs is governed by energy criteria. Energy flow through the ecosystem increases when a predator is introduced into a "producer-reducer" system at steady state. Analysis of the model shows that under certain conditions the presence of the primary predator with its high mineralization ability accelerates the biotic turnover measured by primary production. We, therefore, conclude that for every system it is possible to find a suitable predator able to provide the system with a higher biotic turnover rate and energy consumption. В© 2001 COSPAR.

Аннотация: Experimental and theoretical models of closed 'autotroph-heteretroph' (chlorella-yeast, chlorella- protozoa) ecosystems with spatially separated components have been created and studied. The chart of flows and interaction of components of gas-closed 'chlorella-yeast' system have formed the basis describe mathematically the functioning of the given system, experimental results have been found to agree with computer solution of the problem in terms of quality. Investigation of the experimental model of the 'producer-consumer' trophic chain demonstrated the role of protozoa in nitrogen turnover. 'Production-decomposition' and 'production-grazing-decomposition' cycle models has been theoretically analyzed and compared. The predator has been shown to be a more intensive mineralizer than the reducer component.

Аннотация: Computer simulations of electrooptic interactions in solid molecular systems have been widely used with good effect. In these calculations molecules are usually considered point dipoles (molecule-point approximation), their parameters are taken from free molecules, and summations over the crystal lattice (lattice sums) are done by the Ewald method. Synthesis of effective new systems for electrooptic applications results in large complicated molecules much longer than the intermolecular distances in crystals. To take molecular fragmentation directly into account in this approach requires very long computing time. To simplify this problem, the molecular lattice sums are modified by dividing the molecule into fragments and calculating the lattice sums for each fragment. The results are then averaged over the weight fragment polarizabilities. This weighting coefficient is introduced to take account of the anisotropy of the molecular polarizability distribution over the molecular frame. The rest of the calculations are performed in the usual way. The method has been used to calculate linear and nonlinear optic parameters for some substituted benzene crystals with good results.

Аннотация: The new method of a gap recovery in symbol sequences is presented. A covering is combined from the suitable reasonably short strings of the parts of a sequence available for an observation. Two criteria are introduced to choose the best covering. It must yield the maximum of entropy of a frequency dictionary developed over the sequence obtained due to the recovery, if an overlapping combined from the copies of strings from the available parts of the sequence exists. The second criterion identifies the best covering in case when one has to use any string to cover the gap; here the best covering must yield the minimum of specific entropy of the frequency dictionary developed over the available parts of the sequence against that one developed over the entire sequence obtained due to the recovery. Kirdin kinetic machine that is the ideal fine-grained structureless computer has been used to resolve the problem of the reconstruction of a gap in symbol sequence.

climate modeling -- global temperature dynamics -- temperature-regulating mechanism
Аннотация: Our opinion on the properties of the Earth’s climate system does not coincide with that generally accepted. Statistical analysis shows that, if we put aside the most substantial natural perturbing factors, the long-term global temperature dynamics appears as a step function of time. This dynamics is fundamentally different from the climate system’s continuous response to external anthropogenic effects, which is demonstrated in the models of the Intergovernmental Panel on Climate Change. The variants illustrated by a simple model (the system, affected either inadvertently or externally, changes from one quasi-stationary state to another) seem to be more suitable. © 2016, Pleiades Publishing, Ltd.

Аннотация: In view of previous studies, a list of 46 foods designated for use in bioregenerative life support system was composed. With the help of a computer program, daily sets of foods of plant and animal origin were compiled from the list of foods. The objective function of modeling was intended to minimize the discrepancy between the calculated values of nutrients in daily food sets and NASA nutrition requirements for long-duration missions. The independent variables in the model were the masses of foods restricted by the lower and upper bounds. It was established that a food set is able to comprise 10-46 foods with violation of the NASA nutrition requirements for iron, vitamin B5 and vitamin D daily intakes. Inclusion of 9 foods in a set resulted in a further violation of the NASA standards concerning saturated fat. As the number of foods in a set has increased from 10 to 22, the objective function decreased from 1.0736 to 1.0332, followed by a gradual increase to 1.1233, when the maximum number of foods was selected from the list of foods. The source of uncertainty in the interpretation of modeling results are the standard NASA intakes of magnesium, potassium, zinc, manganese, vitamin C, thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, vitamin E, vitamin K and n-6 fatty acids, given as exact values. Varying the nutrient content of food sets did not significantly affect the value of the objective function. However, some solutions were infeasible, due to the violation of the NASA standard concerning saturated fat. Also, there were food sets in which the scores of sulfur-containing amino acids and threonine were below 100. In order to reliably maintain the scores of essential amino acids above 100 in a food set, it is necessary to maintain a mass ratio of “animal protein/total protein” equal to 2/3 in accordance with the requirement of NASA. © 2019 IAA

Аннотация: The relevance of the work is caused by the need to study seasonal variations in the volume and composition of sedimentation flows in modern lakes and their relationship with weather and climatic factors, which can serve as a basis for reconstructing climatic changes in the past. The main aim: to assess seasonal changes in the mass, velocity and chemical composition of sedimentary material entering Lake Shira on the basis of generalization and analysis of the results of multiyear annual monitoring of the material of sedimentation traps incubated in the lake. Object of the study was the drainless, slightly saline meromictic lake Shira, located in the steppe intermontane depression on the territory of the Republic of Khakassia. Methods: long-term seasonal monitoring of sedimentary material forming bottom sediments using sedimentation traps incubated in the lake; study of the obtained material for a wide range of parameters (biological, hydrochemical, lithological-geochemical, granulometric, etc.) by various conventional methods, including the method of X-ray fluorescence microanalysis on synchrotron radiation beams (XRF-SI), adapted for the study of bottom samples; computer statistical analysis of the data obtained (multiple regression method, cross-correlation analysis, etc.) in order to identify the relationship between regional temperatures and the chemical composition of the deposited material with the construction of a regression model. Results. Based on the study of the amount and elemental composition of the sedimentary material of the seasonal bottom traps of Lake Shira, collected for 2012-2017, a dynamic model of the seasonal influx of sedimentary flows in lakes of this landscape-geochemical type was formulated. It has been established that the most intensive sedimentation of the material occurs in the summer-autumn period, less - in the winter-spring period. At the same time, in spring, the accumulation of allochthonous (terrigenous) aleurite material, supplied with flood waters, predominates; in the summer-autumn period, simultaneously with the deposition of clastogenic pelitic material, biogenic and chemogenic materials are accumulated in sediments in large quantities. In winter, clastogenic and biogenic processes of sedimentation practically stop, only chemogenic sedimentation of carbonates is observed. It was established that the sedimentation of allochthonous material entering the reservoir occurs during two-three months, which indicates a certain inertness of sedimentation. The presence of a stable relationship between the mass and chemical composition of terrigenous material entering the lake with the regional temperature of the near-surface air, which is one of the main regulators of the water balance of the reservoir, is shown.
