MILP‐based customer‐oriented E‐Fleet charging scheduling platform
Authors: Akaber Parisa , Hughes Timothy , Sobolev Sergey
Published: March 2021

Conventional road transport is a significant contributor to greenhouse gas emissions and air pollution. Electric mobile assets (E‐buses, E‐trucks, E‐taxis, and even E‐ferries) are an efficient, low noise, low emission alternative which could—if operated alongside significant renewable energy capacity—help to improve air quality and avoid catastrophic global warming. In this study, a Mixed Integer Linear Programming‐based solution for operating a fleet of E‐mobile assets has been proposed, considering technical and operational characteristics of different fleet elements. It takes into account customer (E‐fleet operator) objectives, such as load balancing and charging cost minimization. Furthermore, the E‐depot charging capacity increase achieved through integrating an energy storage system has been studied and discussed. The results of the optimization have been discussed and reported using a case study (demonstrating peak reduction of up to 50% and total charging reduction of 27%) and the benefits of operating an E‐fleet using the proposed solution have been discussed from economic and technical perspectives.

Neptune-size exoplanets seem particularly sensitive to atmospheric evaporation, making it essential to characterize the stellar high-energy radiation that drives this mechanism. This is particularly important with M dwarfs, which emit a large and variable fraction of their luminosity in the ultraviolet and can display strong flaring behavior. The warm Neptune GJ 3470b, hosted by an M2 dwarf, was found to harbor a giant exosphere of neutral hydrogen thanks to three transits observed with the Hubble Space Telescope Imaging Spectrograph (HST/STIS). Here we report on three additional transit observations from the Panchromatic Comparative Exoplanet Treasury program, obtained with the HST Cosmic Origin Spectrograph. These data confirm the absorption signature from GJ 3470b’s exosphere in the stellar Lyman-α line and demonstrate its stability over time. No planetary signatures are detected in other stellar lines, setting a 3σ limit on GJ 3470b’s far-ultraviolet (FUV) radius at 1.3 times its Roche lobe radius. We detect three flares from GJ 3470. They show different spectral energy distributions but peak consistently in the Si III line, which traces intermediate-temperature layers in the transition region. These layers appear to play a particular role in GJ 3470’s activity as emission lines that form at lower or higher temperatures than Si III evolved differently over the long term. Based on the measured emission lines, we derive synthetic X-ray and extreme-ultraviolet (X+EUV, or XUV) spectra for the six observed quiescent phases, covering one year, as well as for the three flaring episodes. Our results suggest that most of GJ 3470’s quiescent high-energy emission comes from the EUV domain, with flares amplifying the FUV emission more strongly. The neutral hydrogen photoionization lifetimes and mass loss derived for GJ 3470b show little variation over the epochs, in agreement with the stability of the exosphere. Simulations informed by our XUV spectra are required to understand the atmospheric structure and evolution of GJ 3470b and the role played by evaporation in the formation of the hot-Neptune desert.

Published: March 2021

An overview of the substantiation of the relevance of the transition to mass ecological housing construction, which is determined by an acute shortage of housing and a high increase in the cost of electricity, is given. The development of an ecological substantiation of an energy-independent house using the example of a one-story house, taking into account natural and climatic conditions, is presented. The characteristics of the work of all utilized engineering systems are considered. It has been established that the housing and utilities sector, being one of the main sources of air and groundwater pollution, creates a large amount of household waste, which has a detrimental effect on the environmental situation. Renewable energy sources have an inexhaustible supply, since they are obtained from natural processes that will not be exhausted in the foreseeable future. Thus, the prospects for renewable energy sources are in considering them to replace fossil fuels. Economic efficiency is defined, which implies that the energy source is economical both in relation to the net cost of production and in relation to supply. The development of renewable energy sources will play an important role in the transformation and digitalization of the Russian power industry. Technologies of energy storage, intelligent systems for forecasting production and demand, predictive analytics of equipment condition, consumption management and many others will be developed.
Localization of the organic matter production and degradation in two different estuaries
Authors: Vazhova Anna , Zuenko Yury
Published: March 2021

Physical and chemical processes related to primary production of the estuaries of two rivers with different water regime are considered with special attention to their spatial and seasonal variability. Both production and degradation of the organic matter are quantitatively evaluated on the data of non-conservative variation of dissolved inorganic phosphorus concentration in the process of the river water dilution. Contribution of recycling to the phosphorus balance and the estuarine waters productivity is estimated. The organic matter degradation prevailed in the internal part of both estuaries, but its production dominated in their external parts, with a tendency of production lowering and degradation strengthening from spring to autumn. Utilization of the re-mineralized phosphorus in the external estuaries increased their potential productivity by 20-50%, provided by the terrigenous flux with the river water.

Effect of pesticides “Butylcaptax (Russia)” and “Droppa (Russia)” on respiration and oxidative phosphorylation of liver mitochondria of pregnant rats and their embryos
Authors: Alimova Rano , Mirkhamidova Parida , Tuychieva Dilfuza
Published: March 2021

The article provides information on the effect of pesticides - butylcaptax and droppa on respiration and oxidative phosphorylation of liver mitochondria in rat rats and their embryos. It has been shown that butylcaptax and droppa reduce the oxidation of succinate and α-ketoglutarate in the V4*, V3 and Vdnf states and drug conjugation in the liver mitochondria of pregnant animals and their embryos. The most significant inhibition of ADF formation in the respiratory chain of fatal and maternal liver mitochondria occurs via the NAD-dependent pathway, especially when poisoning with butylcaptax on the 19th day of pregnancy. Apparently, inhibition of ADF-stimulated respiration is associated with inhibition of electron transfer along the respiratory chain or is a consequence of inhibition of the transport of phosphate or ADF into mitochondria, which plays a key role in the mechanism of oxidative phosphorylation. A decrease in the conjugation of oxidation and phosphorylation does not create conditions for the accumulation of energy in an utilizable form - in the form of ADF.

Published: March 2021

The features of different methods of feeding calves with colos-trum and their influence on the growth, development and health of young animals have been studied in a comparative aspect. The studies were car-ried out using newborn Holstein heifers at a modern dairy complex. De-pending on the method of feeding, the calves consumed different amounts of colostrum on the first day: with a suckler mother cow - 10.8 liters, when using a suckling bottle and a nipple pail - 8 liters, using the CalfDrencher system - 7 liters. Different volumes and rates of colostrum entry into the digestive system of newborns had a significant impact on its digestion in calf abomasum and the transition of immunoglobulins into blood serum. It was found that only with the sucking method, 6 hours after drinking the first portion of colostrum, the content of immunoglobulins in the blood se-rum of calves was more than 10 mg/ml, which corresponds to the physio-logical norm. In accordance with the intensity of the transfer of immuno-globulins from colostrum to blood serum, cases of disease in calves were distributed in the first month of life, which affected their further growth and development. As a result, the live weight required for the first insemi-nation (at least 420 kg) was achieved by the Holstein heifers in group I at the age of 16 months, in group II - 18 months, in group III - 17 months, in group IV - 19 months.

Operation of subgrades with application of polyurethane binder for its stabilization
Authors: Barabanova Tatiana
Published: March 2021

Slopes of road subbase and subgrade under operation are subjected to deformation and destruction while being affected by atmospheric precipitation, deicing agents and temperature drops. Stabilization of road slopes should proceed throughout the entire life cycle of the road. There arose a need to work out the most effective and durable design solution. Structures being under operation are exposed to external factors that cause washouts and defects of expansion joints. Washouts of geocell reinforcement structures may occur as well. Structural repairs sometimes are not effective, so destructions continue and progress. Analysis of the use of conventional technologies has shown that implementation of a polyurethane binder for stabilization of slopes is the most effective design solution under certain conditions. Binder based on polyurethane, when applied to rock material (crushed stone or gravel), forms a durable structure that is resistant to external influences and has high strength properties. A set of national standards for application of this technology is currently being developed. It is confirmed that the material under consideration meets the requirements of fire protection, sanitation and epidemiology, hygiene, and environmental safety. By these days, this technology has been implemented at more than 30 highway structures in the city of Moscow and in the Moscow and Smolensk Regions.
Improving the energy efficiency of buildings based on the use of integrated solar wall panels
Authors: Schukina Tatyana , Kurasov Ilya , Drapaliuk Dmitry , Popov Petr
Published: March 2021

Frequently used facade glazing makes it possible, on the basis of modern trends in the architecture, to increase the energy efficiency of buildings under construction through the organization of passive solar heat supply. Despite the noted relatively low efficiency of the radiation utilization method recommended for the use, it is possible to increase its indicators by integrating the elements of active solar units in the absorbing layer of the accumulating construction structure. For example, the placement of pipes for the coolant in external enclosing structures will allow year-round exploitation of arrays for passive utilization of solar energy and the use of the obtained heat not only for heating rooms during the cold period of the year, but also for heating water, as well as for absorption chillers in the summer season. The application of the latter contributes to the organization of alternative cooling of the internal blocks of air conditioning systems in the warm period of the year. The listed functions require a different approach in the algorithm of the decisions taken in the design of building structures actively involved in the balance of energy supply. One of the main indicators that determine the possible version of the implementation of the solar radiation utilization system is the achieved temperature potential of the heat flux obtained from the surface of the accumulating layer. The use of the method of sources and the principle of the imposition of fields when solving problems of the depth of embedding and step distance integrated into the surface layer of pipes allows determining the rational range of the values of the specified parameters. This, in turn, is aimed at ensuring the possibility of designing energy-efficient exterior enclosing structures that contribute to the maintenance of the thermal regime required by the multifunctional utilization of solar energy.

Purpose: to analyze the modern display of utopian ideas in architectural activity for the development of innovative directions of organization and forming of the object environment, to identify and define the features of technotopia as a figurative and stylistic direction that combines idealistic and pragmatic principles in architectural creativity. Methods and materials: empirical and theoretical methods of analogy and abstraction focused on analyzing the properties, possibilities and conditions that determine the features of utopian ideas displayed in architectural creativity. A method of generalizing the experience of theoretical knowledge and development in the implementation of innovative technological solutions for architectural objects. Results: A two-level structure of signs of utopia in architectural creativity was developed. An algorithm for transforming ideas about an ideal world is proposed, taking into account the possibilities of practical implementation of technological priorities in architectural activity. The properties of technotopia as a figurative and stylistic direction characterizing the features of the practical implementation of technological priorities of architectural activity have been confirmed. Conclusions: The study of the nature of utopias is one of the key topics and opportunities for the development of promising figurative and stylistic directions in architectural creativity. The fundamental idealistic (utopian) principle of architectural creativity is capable of evolution through integration with the results and possibilities of technological progress of various fields of knowledge. Technological priorities in the organization of architectural space make it possible to significantly expand the possibilities of traditional compositional techniques in solving applied and practical problems of architectural activity.

Published: March 2021

Deployable lightweight structures are studied in the disciplines of architecture, civil engineering, aerospace engineering, mechanical engineering and other fields of their application. The research into these structures in individual fields resulted in a large amount of data sorted out by numerous classifications. The previously made classifications proposed by different authors are presented in this paper by the usage of reasonably unified tables that enabled a direct insight into the essential characteristics of these structures, their analysis and mutual comparison. One of the results of these analyses is the proposal for the unified classification given in a separate table in this paper. The results of interdisciplinary studies have been collected into a unified classification which could be applied for the research in different scientific fields, presenting the basic types of these structures, including individual elements and details with their characteristic features. The proposal of the unified classification of deployable structures is made according to the application of the basic elements used for structure forming. The suggested classification, with the review of the results of the present research, is a significant starting point for the scientists in different disciplines and it provides a detailed insight into the studied characteristics of these structures.
Improving the stability of high embankment slopes on weak foundations
Authors: Kamenchukov Aleksey , Ukrainskiy Ilya , Nikolaeva Gamilia
Published: March 2021

The article considers the issues of assessing the stability of non-standard soil-geological systems in difficult conditions. An analytical review of modern methods and tools for assessing the stability of embankment slopes is carried out. The features of the work of the embankment in the areas of the spread of permafrost are considered. The features of the design of embankments on permafrost soils with the preservation or partial thawing of frozen soils have been studied. Two versions of the calculated static schemes of sliding surfaces are presented: base - subgrade and base - subgrade - pavement. Based on the results of field studies, the physical and mechanical characteristics of the soils of the embankment and the base of the subgrade were determined, which became the basis for mathematical modeling and assessment of the stability of the embankment slopes. In software packages GeoStab and Geo5, based on the finite element method and the results of field studies, digital models of embankments were built on a weak foundation. The calculation of the stability of the system “base - subgrade” under the action of a standard uniformly distributed load has been performed. Two models of the system and the base - subgrade - road surface are considered: without cracks on the rolling strip and with cracks. It was found that coating defects affect the stability of the system only in the presence of an earthquake of medium strength and more. Recommendations for strengthening the slopes of embankments operating in difficult soil-geological conditions are given.

Published: March 2021

The main goal discussed in this article is the creation of tools for the implementation of calculation tasks at the design stage. The proposed method helps to significantly reduce labor, time and money costs both at the design stage and in the subsequent construction of the building. To implement the task, two approaches were used in parametric modeling using two different tools in BIM modeling. With the help of Revit and ArchiCAD, as well as their extensions Dynamo and Grasshopper, solutions were created to speed up the calculations required in the process of implementing projects of varying complexity. The results obtained revealed the main differences in the implementation of one task in two different software packages. Moreover, each of the obtained solutions is flexible and can be used in other projects. Also, these solutions can be upgraded to implement calculations of other characteristics of design solutions in the project. Thus, the task was implemented and applied in the Revit and ArchiCAD project.

Published: March 2021

One of the most important and promising areas of digitalization is to create favorable environment for the population of cities and improve the quality of housing and communal services. “Smart City” concept implemented in many countries provides solutions for this problem. However, the analysis of examples of the implementation of such initiatives indicates that the housing and utilities sector is represented in Russia by a limited number of projects, in particular, the problem of controlling the timing and quality of work in maintaining the housing stock, including the overhaul of residential buildings, remains unresolved. This leads to accidents and does not contribute to creating a comfortable environment for the population. This study is devoted to the analysis of the use of digital technologies in the housing and communal sector and contains recommendations on the creation of an information-analytical system for controlling and monitoring the quality of overhaul repairs of housing.
