Published: November 2020

Abstract
Vessel groundings pose a major risk for maritime safety, constituting 20 percent of all incidents in the last decade. Frequent dredging and bottom mapping are resource intensive solutions currently employed, but these services cannot be maintained with the necessary frequency in all critical areas. While ships are carrying echo sounders to acquire precise and current under keel clearance data, it does not allow the vessel to react to possible deviations from the map data. Within the RoboVaaS project, a service is designed, implemented and tested in simulation. This service consists of one or more small MASS travelling ahead of a merchant vessel, collecting bathymetric data with enough lead time for the merchant vessel to react to possible threats, e.g. by course correction. This service is tested in compliance with the IMO HCD guideline in a quick approach and safe environment using a ship handling simulator. The simulator is augmented by a display system based on an ECDIS map and displaying the bathymetric data in three different scenarios. These scenarios are tested with nautical officers to collect feedback for service design and implementation with trained personnel and show the effectiveness of the chosen human machine interface.

Abstract
The cross-rod system under consideration is widely used in various fields: industrial and civil construction, aircraft and shipbuilding. There are a large number of methods for calculating these structures’ types, based on differential dependencies system of the 4th order, describing the bending of a flat covering. However, the main reason in solving problems for calculating cross-rod systems is the complexity of mathematical calculations and a large amount of labor, since the system is statically indeterminate. It leads to a large number of linear equations’ systems solution with boundary conditions. The use of computers in the calculation of cross-rod systems allows you to make both dynamic and static calculations of building structures with high accuracy. At the same time, simplified ideal schemes are used in the calculation of structures, where the elements are connected to each other either rigidly or pivotally. In real designs, the connections are elastic and cannot always be replaced with ideal analogues, used in the design schemes. The use of ready-made laminated structures allows reducing not only the cost of production, labor intensity and construction in general, but also the totality of all factors, such as the timing of construction and installation work on the reconstruction and overhaul of buildings and structures.

Published: November 2020

Abstract
The article gives an overview of the use of low-temperature geothermal energy sources for heat and cold supply of buildings in areas of Western Siberia. The experience of using geothermal heat pumps shows their economic efficiency and environmental friendliness. An innovative application of the low-temperature energy of the shallow subsurface soil layers is the double use of the underground foundation of a building or another structure as energy active elements of the heat-pumping system. The paper analyzes the problems why green technologies are not developing as dynamically as indicated in the Energy Program of Russia and barriers that prevent the wider use of heat pumps and systems in the heat and cold supply of buildings in the Siberian region. These include considerable regulatory and investment barriers, as well as lack of awareness about renewable energy and energy efficiency. Further, market entry remains challenging in Russia that has not fully liberalised its energy market. Furthermore, entrenched interests in conventional energy resources represent a significant barrier to effective legislation and policy implementation. Thus, huge conventional resources of oil, gas and coal in Siberia region, neighboring to Novosibirsk, Omsk and Altay districts are other obstacles to the introduction of renewable green technologies. Some examples on the limitation of barriers to geothermal heat pumps systems application in building construction are given.
Research of reagent treatment methods for mine waters from sulfates

Published: November 2020

Abstract
The most important environmental challenge for the mining industry is the efficient treatment of mine wastewater. The solution to this problem is complicated by the large volumes of this wastewater, which requires significant material and economic costs. Analysis of the wastewater drainage mine composition “Limestone” shows that it is contaminated with impurities, in quantities that significantly exceed the admissible concentration limit for wastewater discharged into water bodies fish of sulfates, salts (dry residue) and calcium. So, the sulfates concentration exceeds admissible concentration limit by about 9–10 times, salinity - by 1.5–1.6 times, and calcium – by almost 2 times. There is also a several-fold excess in suspended solids, in petroleum products, iron, copper and magnesium, and other ingredients. However, the main pollution of mine wastewater needs to be cleaned is sulfates, the total salinity and calcium concentration will accordingly decrease after the water treatment process. Sulphates are the most difficult to remove pollution, because they are in dissolved form and have a high concentration. Therefore, the proposed research work is devoted to the development of effective methods for treating mine water in a given mine from sulfates in the first place.

Abstract
Improvement of dowel joints in order to increase their load-carrying capacity and reliability at the present time remains actual one. A special place among them is occupied by connections with the use of dowel plates. In order to increase the bearing capacity of metal nailed plates developed in NGASU (Sibstrin) with the use of reinforced dowel it is suggested to strengthen the nailed plates in metal plates by means of tight installation on the last metal stamped gear washers. In order to determine the strength and deformability of the developed connections they were prepared and tested under the action of short-term loads along and across the fibers. On the basis of the received data the analysis of short-term bearing capacity and deformability of the offered joints has been carried out. The method of calculation of such connections on limiting states of the first group is offered. The interaction of the limiting load-carrying capacities obtained on the basis of the proposed method with the results of short load action tests of the compounds under consideration was performed.

Construction Technology of Enclosing Structures by Means of 3D Printing with One-Stage Polystyrene Concrete
Authors: Molodin V , Gasenko I , Timin P 
Published: November 2020

Abstract
Today, layer-by-layer printing of enclosing structures with a 3D printer is the formation of a permanent formwork from a cement-sand mixture, followed by concreting and thermal insulation of the structure using standard technologies and widespread use of manual labor. Despite the use of robotization, 3D printing is only partially involved in the construction process and does not solve the issue of increasing labor productivity. This, and other disadvantages, hinders its widespread use in construction. 3D printing with one-stage polystyrene concrete is devoid of many traditional printing disadvantages, which allows forming a layer of heat-insulating and structural material over the entire wall width in one pass during the construction process. It was possible to overcome the inhomogeneity of a wall thermal conductivity due to the “cold bridges”, lower layers spread that did not have time to grab and ability to work only at high temperatures. The approbation of the technology is demonstrated its feasibility and opportunities for improvement.

Authors: Sahakyan S V , Yedoyan T V 
Published: November 2020

Abstract
The dynamics of water intake for different purposes from the Ararat artesian basin has been studied in connection with the overuse of water by fish farms in Ararat Valley. It has been shown that as a result of those negative processes the surface area of groundwater with positive pressure has decreased by 3 times, 31 communities are partially or completely deprived of water obtained from fountain boreholes for various purposes. As a consequence of the decline in groundwater level irrigation norms of agricultural crops have increased by 25% or about 14 million m3, the physical properties of soils have deteriorated on the area of 7 thousand hectares. It has been proposed to reuse discharge waters from fish-farms for irrigation. Through technical and economic calculations, it has been shown that in case of solar station-pump station-irrigation pipeline construction the cost price of irrigation water per 1 m3 is 8-10 times cheaper than in case of reservoir construction and irrigation water supply systems.
Problems of conversion of diesel locomotives to gas-diesel cycle
Authors: Kossov E , Asabin V , Kossova L 
Published: November 2020

AbstractThe article focuses on the problem of ensuring the required parameters for gas-air mixture in light load and idle modes. A mathematical modeling of the process in the gas-air duct of the diesel generator 1-PDG-4 was conducted during air blow-off in compressor and throttling at the diesel inlet. It was found that conversion of locomotive engines to gaseous fuel at idle speed can meet the required stoichiometric ratio of gas-air mixture only if air throttling processes at the engine inlet are combined with the engine in the shut-down mode of a cylinder bank.

Published: November 2020

Abstract
The article deals with the problem of organizing train traffic on sections with branches, analyzes possible separate routes on the “trunk” and “branch” sections, as well as routes with «fork» traffic. The authors emphasize the need to comply with a number of conditions that take into account the interests of passengers and suburban companies for the organization of passenger traffic on railway transport. The goal function is set to minimize the difference between the mileage of empty seats (as a condition that reflects the interests of the suburban company) and the overpopulation of the train (as a criterion that ensures a comfortable ride for the passenger). To solve this problem, the authors suggest using a genetic algorithm as a tool that allows you to perform a directed search of competitive options. The article describes the method of applying the genetic algorithm, the formation of “parent” variants and “offspring” variants, compliance with a number of restrictions and ranking of «offspring» variants for the selection of the best “species”.

Published: November 2020

Abstract
The behavior of a 16-storey residential building with a stiffness core during the earthquake of March 26, 2018 is analyzed. The building is located 100 meters from the tectonic fault. The absence of resonance phenomena of the building during a local earthquake was established. On the distribution of accelerations in the horizontal plane, the effect of “eight” was found. An increased value of acceleration in the vertical direction at the level of the technical floor was revealed. This could be due to the presence of a tectonic fault near the building. The energy characteristics of the building and the impact are determined, the Arias integral and the cumulative absolute velocity are calculated. At the basement level, the period of the spectrum maximum is of the order of 0.1 sec. It is established that the building oscillates in the sum of the vibration modes

Published: November 2020

Abstract
Radon indoor build-up poses a serious health threat, increasing the risk of lung cancer in those exposed. Effective limitation of the radon intake from the soil is possible only through the modern building technologies and materials use with high radon-protective characteristics in the building underground part. The ensuring radiation safety complexity is that, depending on the instantaneous soil-atmosphere-building system state, both diffusion and convection can act as the radon intake dominant mechanism, and each of these transfer mechanisms requires its own radon protection measures set. In the article, the dominance areas of each transfer mechanisms are established on the theoretical researches, and an approach to determining the radon load on the building underground shell is proposed.

Published: November 2020

Abstract

Purpose
A study was conducted to compare the accuracy of medication histories compiled by pharmacy technicians with histories obtained through the usual multidisciplinary process.

Methods
A retrospective cohort study was conducted at a community teaching hospital from January 2017 through February 2018. Inclusion criteria included patient age of at least 18 years, use of 1 or more medications at the time of admission, and hospital admission through the emergency department. Each electronically documented medication history was assessed for accuracy. The objective was to compare the accuracy of pharmacy technician–collected medication histories to those obtained through the usual multidisciplinary process.

Results
Of 215 patients screened, 183 were included in the study: 91 patients whose medication histories were obtained through the usual multidisciplinary process and 92 whose medication histories were collected by pharmacy technicians. Overall, documentation for 1,773 medications listed in medication histories was reviewed. The primary outcome of medication history accuracy occurred 38% of the time with the usual multidisciplinary process and 70% of the time with pharmacy technician collection of medication histories (P &lt; 0.001).

Conclusion
The study showed that the accuracy of medication histories was improved when histories were obtained by pharmacy technicians instead of via the usual multidisciplinary process.
The gradation puzzle of intellectual assurance
Authors: Zhang Xiaoxing 
Published: November 2020

Abstract
The Cartesian thesis that some justifications are infallible faces a gradation puzzle. On the one hand, infallible justification tolerates absolutely no possibility for error. On the other hand, infallible justifications can vary in evidential force: e.g. two persons can both be infallible regarding their pains while the one with stronger pain is nevertheless more justified. However, if a type of justification is gradable in strength, why can it always be absolute? This paper explores the potential of this gradation challenge by rejecting Fumerton's recent ‘semantic decision' solution. On Fumerton's suggestion, the putative gradation of infallible justifications is essentially semantic. It concerns only how we use the relevant term but not how well we perceive the truth. Regardless of its intuitive appeal, Fumerton's solution does not cover all the related situations. There is an irreducibly epistemic sense in which infallible justifications vary in degrees.
A comprehensive drug repurposing study for COVID19 treatment: novel putative dihydroorotate dehydrogenase inhibitors show association to serotonin–dopamine receptors
Authors: Berber Burak , Doluca Osman 
Published: November 2020

AbstractDihydroorotate dehydrogenase (DHODH) is a key enzyme required for de novo pyrimidine synthesis and it is suggested as a target for COVID19 treatment due to high pyrimidine demand by the virus replication in the infected host cells as well as its proven effect of blocking of cytokine release by the immune cells to prevent inflammation leading to acute respiratory distress. There are a number of clinical trials underway for COVID19 treatment using DHODH inhibitors; however, there are only a small number of known DHODH antagonists available for testing.Here, we have applied a methodology to identify DHODH antagonist candidates, and compared them using in silico target prediction tools. A large set of 7900 FDA-approved and clinical stage drugs obtained from DrugBank were docked against 20 different structures DHODH available in PDB. Drugs were eliminated according to their predicted affinities by Autodock Vina. About 28 FDA-approved and 79 clinical trial ongoing drugs remained. The mode of interaction of these molecules was analyzed by repeating docking using Autodock 4 and DS Visualiser. Finally, the target region predictions of 28 FDA-approved drugs were determined through PASS and SwissTargetPrediction tools.Interestingly, the analysis of in silico target predictions revealed that serotonin–dopamine receptor antagonists could also be potential DHODH inhibitors. Our candidates shared a common attribute, a possible interaction with serotonin–dopamine receptors as well as other oxidoreductases, like DHODH. Moreover, the Bruton Tyrosine Kinase-inhibitor acalabrutunib and serotonin–dopamine receptor inhibitor drugs on our list have been found in the literature that have shown to be effective against Sars-CoV-2, while the path of activity is yet to be identified.Identifying an effective drug that can suppress both inflammation and virus proliferation will play a crucial role in the treatment of COVID. Therefore, we suggest experimental investigation of the 28 FDA-approved drugs on DHODH activity and Sars-CoV-2 virus proliferation. Those who are found experimentally effective can play an important role in COVID19 treatment. Moreover, we suggest investigating COVID19 case conditions in patients using schizophrenia and depression drugs.

Abstract
African swine fever virus (ASFV) poses serious threats to the pig industry. The multigene family (MGF) proteins are extensively distributed in ASFVs and are generally classified into five families, including MGF-100, MGF-110, MGF-300, MGF-360 and MGF-505. Most MGF proteins, however, have not been well characterized and classified within each family. To bridge this gap, this study first classified MGF proteins into 31 groups based on protein sequence homology and network clustering. A web server for classifying MGF proteins was established and kept available for free at http://www.computationalbiology.cn/MGF/home.html. Results showed that MGF groups of the same family were most similar to each other and had conserved sequence motifs; the genetic diversity of MGF groups varied widely, mainly due to the occurrence of indels. In addition, the MGF proteins were predicted to have large structural and functional diversity, and MGF proteins of the same MGF family tended to have similar structure, location and function. Reconstruction of the ancestral states of MGF groups along the ASFV phylogeny showed that most MGF groups experienced either the copy number variations or the gain-or-loss changes, and most of these changes happened within strains of the same genotype. It is found that the copy number decrease and the loss of MGF groups were much larger than the copy number increase and the gain of MGF groups, respectively, suggesting the ASFV tended to lose MGF proteins in the evolution. Overall, the work provides a detailed classification for MGF proteins and would facilitate further research on MGF proteins.
