Authors: Zelentsov L B , Mayilyan L D , Pirko D V 
Published: September 2020

Abstract
The article discusses the issues of automating the company standards’ development for labor consumption taking into account the projects’ uniqueness and the significant impact of the human factor on labor productivity, which can be indirectly measured at the stage of operational management with the pace and work intensity. In the proposed method, due to the higher frequency of information retrieval and the use of the integrated moving average model (ARIMA), at the early stage of the design work, it is possible to identify and predict their possible deviations from the planned time parameters, and then based on this, analyze and make the corrective management solutions to optimize their time parameters. This approach, combined with the leading design specialists’ expert evaluations, makes it possible to set the planned values for the complexity and duration of work, which are then specified and updated during the specific project’s implementation. The use of the methodology is considered in the context of the application for the collection and processing the large amounts of information of an intelligent design management system (IMS “Design”) developed at DSTU.

Published: September 2020

Abstract
At present, both in Russia and abroad, a new line of work is developed to comprehensively automate the functions of monitoring and controlling security systems, life support and technological processes of potentially dangerous, unique and technically complex objects (high-risk objects), which can also include car interchanges tunnel type. However, these works are unsystematic and do not fully solve the prevention and liquidation issues of emergency situations at the above-mentioned facilities. Moreover, in case of incorrect design of the above-mentioned systems, they can contribute to the deaths of people on the site and beyond. This is confirmed by the accidents’ statistics at these facilities including the road junctions of the tunnel type. The accidents causes’ analysis at high-risk facilities showed that they are largely stipulated by the incorrect definition of vulnerability (threats) assessment for the designed facilities and the facilities under construction. Thus, the model development for assessing the vulnerability of tunnel-type road junctions is an urgent task. To achieve this goal, the main causes of emergencies at tunnel type road junctions are considered and based on them, using a system analysis method and experimental theory, a three-dimensional model that allows, with the expert assessments, to determine the susceptibility of tunnels to various threats types, is developed and tested.
Working hypotheses on the hydropower resources’ involvement in the structure of the mountainous areas’ economic framework
Authors: Kalov R O , Kiloev D D , Elmurzaev R S 
Published: September 2020

Abstract
The hydropower resources of the Kabardino-Balkarian Republic (Kabardino-Balkaria (KBR)) are estimated at 3 thousand MW, however, the total generation of the functioning hydroelectric power stations does not exceed 160 MW, or only 5.3% of the potential river capacity [1]. Neither the presence of a series of the programs for hydropower development, nor the favorable conditions for the technologies’ import, nor the economic feasibility studies for the projects have improved the situation. The persistently not decreasing imbalance in the electric power industry structure in the mountain zone became the motive for a new attempt to actualize the indicated problem. The implementation of the idea will be an important step in “embedding” the Russian research in the field of mining hydropower in the international context of the transition to the renewable energy sources.
The purpose of the article is to publicly discuss the most important agenda for the republic - the overdue optimization of the electric power industry structure, the understanding of the possible options for involving the mountain rivers with slightly changed hydrological parameters. The objectives of the publication are:
– the suitability study of the small tributaries supplying the main mountain rivers for generating electricity;
– identification of the river sections, in the first approximation, possessing the favorable technical and economic indicators, for involvement in the electric power industry;
– study of the necessity and possibilities of regulating the mountain rivers’ flow;
– formulation of the hydropower units’ relative position working hypothesis. The authors consider the underestimated hydropower potential of high mountain small tributaries of the rivers, which have high water pressure (from 25 to 100 m). The relevance of their involvement is also due to the steady growth of point energy consumers in the mountains, for which the autonomous power plants are the optimal source of energy supply. Such suppliers of energy resources can be small and ultra-small hydropower plants, the technological characteristics of which adequately fit into the natural specifics of the mountain valleys [2].
The article does not share the widespread opinion about the categorical inadmissibility of the water-accumulating structures’ creation in the mountains. Without denying the presence of limiting environmental and technological factors for the water-regulating objects’ construction in the mountain zone, the article draws attention to the fact that they are not critical and are completely solvable by searching for compromises, including the choice of the optimal alignment for placing the hydraulic units.

Abstract
Engineering and environmental support of safe urban space is an important scientific and practical task, since it is based on the consideration of the territorial natural factors, the introduction of design and planning solutions for the urban and suburban areas’ development, the use of environmentally friendly materials in construction and operation. It is especially important to conduct the research on environmental risks in coastal areas of the cities that have recreational facilities. The goals and objectives of the research are to clarify the features of the city plans’ impact on the formation of the main environmental territorial problems (the level of the environmental components’ pollution, landscape changes, waste management) and evaluate the current environmental status using the example of Yalta to develop the environmental engineering recommendations for their solution. In the process of systematic selection of grounds and soils in the main functional areas (resort-recreational, residential, transport-industrial, agricultural and nature reserve), several categories of pollution were identified: conditionally clean territories, weak pollution of the territories, average pollution of the territories, dangerous pollution of the territories. Based on the field studies and their engineering processing, eight zones of environmental risk were identified within the territory of the Big Yalta: a waste landfill near the village Gaspra; the mouth of the Vodopadnaya river and the adjacent water area of the Yalta city beach; channel, floodplain and wellhead parts of the river. The fast and adjacent waters of the Yalta Passenger Seaport; the mouth of the river Avunda and the adjacent waters of the beaches of the village Gurzuf and YRC “Artek”. As a result of the study, the dependences of the ecological situation formation in the coastal urban areas on the various urban areas planning decisions features (for example, Big Yalta).

Abstract
Water resources use as a renewable natural resource on all hierarchical basin geosystems levels of within the Earth biosphere, in almost all types of economic and other activities carried out by intra-basin or inter-basin water flow regulation and redistribution (surface, underground), quantitative and qualitative indicators, formed within the spatial limits of the basin system under consideration. For the water flow regulation within the considered river hydrographic seasonal or multi-year regulation network, the reservoirs are built, including the necessary complex hydrotechnical and related facilities, providing the selection of the estimated water flow (Q m3 / s) from water body with a subsequent transportation to specific water users and water consumers. For water resources use in various sectors of economic and other activities within about 10 of the basin geosystems in the Kuban, Terek and Lower Don rivers water facilities were built last century. According to the current regulatory environmental requirements at the design stage, construction and subsequent operation an urgent need to carry out the environmental impact assessment of water facilities arose. The construction objects referred to as “Facilities” and related to the water use with a systematic approach as a way to describe the processes of interconnection, interaction and the relationship between the natural, man-made components and the population developed the methodology foundations for creating and developing a class of natural-technical systems “Environment - Facility – Population” on the water resources use in the economic activity industries. The developed methodology basis for this class of natural-technical systems found practical application at the design, construction and operation stages water objects of activity, referred to as “Facilities”, with the implementation of the existing regulatory environmental requirements. In the methodology foundations development for the creation and development of this class the natural-technical systems, the concept of the dominant role of the whole was formulated, which defines the dominant effect of natural processes in the water flow formation (surface, underground) in the zones of “Facility” influence within the considered basin geosystem. For the considered class of systems according to the study results, such basic system concepts as structure, component, element, the dominant role of the whole, including the concept of natural and technogenic components as well as the environmental acceptability are defined.

Authors: Agashkov E , Belova T , Terekhov D , Loboda Olga 
Published: September 2020

Abstract
In the compound feedstuff production, one of the main problems is the dust emission at all stages of production. The most significant dust emission occurs at the raw materials acceptance stage, where the concentration of dust can be many times higher than the maximum permissible values. The impact of dusts and their capture depends on the dispersed dust composition, and since the raw materials come in different types (bran, wheat, corn, sunflower meal, etc.), the dispersed dust composition is complex. For this reason, it becomes necessary to study their dispersed composition. The article presents the analysis results on some types of the dispersed dust, which generated in the air of the working area on feed mill reception center.
Concerted and birth-and-death evolution of 26S ribosomal DNA in Camellia L.
Authors: Zhang Min , Tang Yi-Wei , Xu Ying , Yonezawa Takahiro , Shao Yang , Wang Yu-Guo , Song Zhi-Ping , Yang Ji , Zhang Wen-Ju 
Published: September 2020

Abstract

Background and Aims
The ribosomal DNA (rDNA) gene family, encoding ribosomal RNA (rRNA), has long been regarded as an archetypal example illustrating the model of concerted evolution. However, controversy is arising, as rDNA in many eukaryotic species has been proved to be polymorphic. Here, a metagenomic strategy was applied to detect the intragenomic polymorphism as well as the evolutionary patterns of 26S rDNA across the genus Camellia.

Methods
Degenerate primer pairs were designed to amplify the 26S rDNA fragments from different Camellia species. The amplicons were then paired-end sequenced on the Illumina MiSeq platform.

Key Results
An extremely high level of rDNA polymorphism existed universally in Camellia. However, functional rDNA was still the major component of the family, and was relatively conserved among different Camellia species. Sequence variations mainly came from rRNA pseudogenes and favoured regions that are rich in GC. Specifically, some rRNA pseudogenes have existed in the genome for a long time, and have even experienced several expansion events, which has greatly enriched the abundance of rDNA polymorphism.

Conclusions
Camellia represents a group in which rDNA is subjected to a mixture of concerted and birth-and-death evolution. Some rRNA pseudogenes may still have potential functions. Conversely, when released from selection constraint, they can evolve in the direction of decreasing GC content and structural stability through a methylation-induced process, and finally be eliminated from the genome.
Flies improve the salience of iridescent sexual signals by orienting toward the sun
Authors: White Thomas E , Latty Tanya 
Published: September 2020

Abstract
Sunlight is the ultimate source of most visual signals. Theory predicts strong selection for its effective use during communication, with functional links between signal designs and display behaviors a likely result. This is particularly true for iridescent structural colors, whose moment-to-moment appearance bears a heightened sensitivity to the position of signalers, receivers, and the sun. Here, we experimentally tested this prediction using Lispe cana, a muscid fly in which males present their structurally colored faces and wings to females during ground-based sexual displays. In field-based assays, we found that males actively bias the orientation of their displays toward the solar azimuth under conditions of full sunlight and do so across the entire day. This bias breaks down, however, when the sun is naturally concealed by heavy cloud or experimentally obscured. Our modeling of the appearance of male signals revealed clear benefits for the salience of male ornaments, with a roughly 4-fold increase in subjective luminance achievable through accurate display orientation. These findings offer fine-scale, causal evidence for the active control of sexual displays to enhance the appearance of iridescent signals. More broadly, they speak to predicted coevolution between dynamic signal designs and presentation behaviors, and support arguments for a richer appreciation of the fluidity of visual communication.

ABSTRACTA better understanding of genetic influences on early white matter development could significantly advance our understanding of neurological and psychiatric conditions characterized by altered integrity of axonal pathways. We conducted a genome-wide association study (GWAS) of diffusion tensor imaging (DTI) phenotypes in 471 neonates. We used a hierarchical functional principal regression model (HFPRM) to perform joint analysis of 44 fiber bundles. HFPRM revealed a latent measure of white matter microstructure that explained approximately 50% of variation in our tractography-based measures and accounted for a large proportion of heritable variation in each individual bundle. An intronic SNP in PSMF1 on chromosome 20 exceeded the conventional GWAS threshold of 5 x 10−8 (p = 4.61 x 10−8). Additional loci nearing genome-wide significance were located near genes with known roles in axon growth and guidance, fasciculation, and myelination.

Abstract

Background
Lymphoma is a dreaded complication of inflammatory bowel diseases [IBD]. Knowledge about lymphoma in patients with IBD is limited to epidemiological data and the description of risk factors. We performed a systematic review to describe the clinical characteristics and prognosis of lymphoma in patients with IBD.

Methods
Electronic databases were searched up to June 1, 2020. All published clinical characteristics of lymphoma occurring in patients with IBD were collected.

Results
Eleven studies were included. A total of 589 lymphomas were described in patients with IBD. As seen in de novo lymphoma, non-Hodgkin’s lymphoma [NHL] was the most common histological subtype [83.9%]. Diffuse large B-cell lymphoma [DLBCL] and follicular lymphoma were the most well-represented NHL in patients with IBD [30% and 13% respectively]. Two main differences were observed in comparison with de novo lymphoma: primary intestinal lymphoma [PIL] represented a large proportion of lymphoma in patients with IBD [22–75%] whereas mucosa-associated lymphoid tissue [MALT] lymphoma was under-represented. Epstein–Barr virus [EBV]-positive status was observed in a large proportion of tumours [44–75%]. Survival data of lymphoma in patients with IBD were similar to those of de novo lymphoma.

Discussion
This systematic review first highlights that PIL [especially DLBCL subtype] is significantly more frequent in patients with IBD and represents the most common entity. Conversely, MALT lymphoma is extremely rare in the IBD population. However, the overall quality of the evidence is low. Further studies are required to better define lymphoma characteristics in patients with IBD.
