Open Science News Informing System for Scientific Libraries

The purpose of the study is to theoretically and practically substantiate the need to introduce an online news information system into library practice as part of the information support of scientific activities (on the example of Open Science). The work theoretically substantiates that improving the news information system in libraries is necessary in connection with the development of technology, open science, library activities and the rapid growth of disparate sources of information. The experience analysis of 130 libraries in presenting various news information products has led to the conclusion that the implementation of news information requires appropriate technology that would allow us to model the sequence of processes and operations for generating news library and information products.As a result the model of a news information system on open science is developed, which allows searching, collecting, processing, and synthesizing news information on open science, as well as creating, posting and distributing information products, their qualitative and quantitative assessment of effectiveness to be made. It has been implemented on the web platform of the State Public Library for Science and Technology of the Siberian Branch of RAS “Library for Open Science” in January 2023 and demonstrates a gradual increase in the number of all web analytical indicators of news information products created on its basis.

Associations of the rs1132896 polymorphism of the matrix metalloproteinase type 2 gene with the development of acute cerebrovascular accident: prospective case–control study

BACKGROUND: The study focused on the identification of new genetic predictors in the Russian population, particularly associations of the rs1132896 polymorphism of the matrix metalloproteinase type 2 gene (MMP-2) with the development of acute cerebrovascular accident (ACVA).
 OBJECTIVE: To investigate the relationship of rs1132896 gene MMP-2 polymorphisms with ACVA development.
 MATERIALS AND METHODS: The prospective, case–control study enrolled 318 patients with stroke (main group) and 323 controls (control group). The age of the patients in the main group ranged from 32 to 69 [57.0; 51.0–62.0] years. In the control group, the age of the patients ranged from 37 to 68 [55.0; 51.0–62.0] years, which was comparable to that of the main group. Sexual dimorphism was as follows: 191 men (age [56.5; 51.0–62.0]) and 127 women (age [57.0; 51.0–62.0]). The sex composition in the control group corresponded to that in the main group: 214 men (age [55.0; 51.0–62.0]) and 109 women (age [55.0; 51.0–62.0]). The main group underwent clinical examination, computed tomography of the brain, electrocardiography, echocardioscopy, duplex ultrasound scanning of the extracranial brachiocephalic arteries, 24-h monitoring of blood pressure and heart rate, and analysis of the blood coagulation system. Molecular genetic research was conducted at a branch of the Institute of Cytology and Genetics of the Siberian Branch of RAS (Novosibirsk). All patients provided written informed consent to participate voluntarily in the study. The duration of the study was 3 years, starting in 2019. The primary study endpoint was a diagnosis of stroke, verification of concomitant cardiovascular pathology, and risk factors for stroke development. Statistical processing of the results was performed using SPSS Statistics v. 22 (IBM Corp., USA) and MedCalc 22.006 (Microsoft, USA). When comparing extended variables, the Mann–Whitney U-test was used. Discrete values were compared using Pearson’s χ2 test.
 RESULTS: When analyzing statistical significance, a predominance of the homozygous CC genotype was recorded in the group of male patients with stroke: n=24 (12.6%) vs n=20 (9.3%; p=0.0324). In addition, in the group of women, a statistically significant predominance of the heterozygous CG genotype was noted in women with stroke: n=67 (52.8%) vs n=42 (38.5%; p=0.0420).
 CONCLUSION: The homozygous CC genotype in men and the heterozygous CG genotype in women may be genetic predictors of the development of ACVA. The study of genetic factors in the development of ACVA is necessary to create a personalized approach to patient management at the outpatient and inpatient stages of medical care.

The Memorial Electronic Information Resource Dedicated to the Baikal Researcher M. M. Kozhov

Scientific libraries are intermediaries between science and society; they concentrate scientific and popular scientific information for a wide range of users. The information block: science – library – society works. Libraries solve the issues of book preservation, documentary, archival heritage of scientists through various forms of preservation and popularization of the achievements of regional science: work with the rare collection of scientific publications (study of marks, book plates, autographs, etc. on books), publication of articles about scientists, creation of bibliographic and biographic databases (DB) and other electronic information publications of own generation.Communicative interaction between libraries, science and society is constantly expanding, including various new components of the popularization of science among young people than attract young people to science and cause interest in the profession of a scientist. The article describes the work of the Central Scientific Library of the Irkutsk Scientific Center of the Siberian Branch of RAS in this direction on the example of the organization of electronic memorial library of Baikal scientist, Professor Mikhail Mikhailovich Kozhov.

The core of the potential of Siberian science

This article attempts at a historical and cultural analysis of the two-volume Russian Academy of Sciences. Siberian branch. Personal composition. An opinion is expressed about the relevance and prospects of publishing scientific and reference editions representing full members and corresponding members of the Russian Academy of Sciences. It is shown that the assignment of highest academic titles to Siberian scientists is based on the traditions of the Russian Academy of Sciences, the scientific and organizational principles of the RAS Siberian Branch, the personal qualities of scientific leaders, and the achievements of the research teams headed by them.

Analysis of “historical” DNA of museum samples resolve taxonomic, nomenclature and biogeography issues: case study of true lemmings

Historical DNA of museum specimens is of paramount importance in elucidation of complex nomenclature issues and a priceless source of material gathered during preceding centuries in hardly accessible today sites. Here we report the results of genotyping type specimens of Lemmus obensis bungei Vinogradov, 1925 from the collection of the Zoological Institute RAS and specimens of lemmings from the upper streams of the Omolon River, identified as L. amurensis from the collection of the Institute of Systematics and Ecology of Animals, Siberian branch of RAS. The genetic profile of the type specimens in the first case was crucial for the nomenclatural solution as these specimens are from the point of the major evolutionary divergence on the Lena River. The results of the study convincingly showed that the lectotype belong to the eastern mitochondrial lineage of L. sibiricus. Therefore, if ever in the further studies it would be conclusively shown that this mitochondrial lineage may become a valid taxon of any rank, then names “novosibiricus”, “ognevi”, “portenkoi” will become younger synonyms of “bungei”. The new obtained sequences of the specimens from the Omolon prove initially wrong assignment and represent L. sibiricus eastern lineage.

Study of impact strength of C-Mn-Si composition metal after wire-arc additive manufacturing (WAAM)

The results of study of impact strength of C-Mn-Si composition metal after wire-arc additive manufacturing (WAAM) are presented. It was established that destruction of the samples of such composition at the temperatures below tough-brittle transition occurs both via tough and brittle mechanisms. The samples manufactured in the direction along built-up welding are characterized by essentially lower impact strength comparing with those manufactured in vertical direction of samples cutting. Impact strength of the samples made of 09G2SA standard steel is substantially lower than for C-Mn-Si composition metal which was obtained via additive technology. Fractographic analysis of fractures for C-Mn-Si compositions manufactured via additive technology using carbon dioxide and gas mixture displays tough pit destruction type. The samples with high impact strength are characterized by forming of cleavage facets after tough crack propagation to the sample middle, what is accompanied by significant widening opposite to a notch and narrowing under a notch. The samples with low impact strength are characterized by forming of brittle fracture directly under a notch without essential sample plastic deformation. It is shown that built-up welding with partial or complete recrystallization of rolls is required for forming of cold-resistant metal structure. In this case, order of rolls location, heat input and parameters of welding conditions make the direct effect on shape, geometrical dimensions, fusion penetration and number of rolls, as well as on size and morphology of the structural components, percent relation between cast and recrystallized microstructure of seam metal. The complex of these factors finally determines structural state and cold resistance of seam metal. The materials for this publication were prepared using the results of investigations, which were conducted within the framework of the program of activity of "Baikal" interregional educational center of global level, according to the priority direction "Processing of industrial wastes", with use of equipment of the Shared knowledge center of isotope and geochemical researches of the Institute of Geochemistry of RAS Siberian branch.

Structural formation of Ti – Al – B composite as a function of the method used to obtain and introduce Boron

This paper looks at the possibility of obtaining ternary borides with a nanolaminate structure (of the MAX phase type) in the Ti – Al – B system by self-propagating high-temperature synthesis (SHS). Different methods were used for introducing boron and titanium. Thus, they were introduced in the form of powders of elemental boron and titanium and in the form of compounds of TiH2 and AlMgB14 (“hydride technology”). Titanium hydride was obtained by annealing the powder at 450 оС in a continuous hydrogen flow. The obtained titanium hydride was mixed with aluminum powder and pressed at a pressure of 6.63·106 Pa. Workpieces with a diameter of 2 cm and a thickness of 0.2 cm were produced, which were then annealed under a programmable temperature regime at 620 оС (below the aluminium melting temperature). The second type of workpieces was obtained by combining titanium hydride with aluminum powder and B/AlMgB14. This mixture was then pressed at a pressure of 6.63·106 Pa. The resulting workpieces (with a diameter of 2 cm and a thickness of 0.2 cm) were annealed at 1.000 оС. The high-boron compound of AlMgB14 was obtained by SHS. The use of the hydride technology leads to the formation of new phases: borides and titanium aluminides. Ternary borides (Ti2AlB) were not found. The authors use the results of a microstructural study and an X-ray energydispersive analysis of the samples, as well as element distribution maps, to demonstrate the possibility of obtaining ternary laminate compounds (of the MAX phase type) in the Ti – Al – B system by SHS using elemental powders. The SHS products are not a homogeneous ternary phase. Ternary laminate borides are located in the Ti3Al intermetallide matrix. All the synthesis techniques used in this research lead to the formation of multiphase products.The work was carried out within the framework of the State assignment of the Tomsk Scientific Center of Siberian branch of RAS, project No. 121031800 148-5 (synthesis of samples via SHS method).The work was carried out under financial support of the Ministry of Education and Science of Russian Federation within the framework of the State assignment No. FSWM-2020-0028.Investigations of microstructure via SEM method were conducted using the equipment of the Tomsk regional common use center of the National Research Tomsk State University (the grant of the Ministry of Education and Science of Russian Federation No. 075-15-2021-693 (No. 13.ЦКП.21.0012)).

ВЫЖИВАЕМОСТЬ И ЗИМОСТОЙКОСТЬ ГЕНОТИПОВ ORIGANUM VULGARE L. В УСЛОВИЯХ СЕВЕРНОЙ ЛЕСОСТЕПИ ТЮМЕНСКОЙ ОБЛАСТИ

The aim of the research is to study the collections of oregano for winter hardiness in the conditions of the Northern forest-steppe of the Tyumen region in order to select the best genotypes. The material for the study was 23 specimens of oregano, collection selections were taken from the collection of the All-Russian Institute of Plant Genetic Resources named after N.I. Vavilov, as well as from different regions. N.I. Vavilov, as well as from different regions of the Tyumen region. The experiment was planted in 2017 using the seedling method. Field studies were conducted in 2017-2019 in the experimental field of the Research Institute of Agriculture of the Northern Trans-Ural - Branch of the Federal Research Center Tyumen Scientific Center of the Siberian Branch of RAS (Moskovsky settlement, Tyumen district), which is located in the northern forest-steppe. The soil is dark grey forest, heavy loam. The reaction of the soil solution in the salt extract is 5.5...6.8 (GOST 26483-85). Soil humus content (on absolutely dry matter) was 1,50...4,75 % (GOST 26213-91), P2O5 was 7,6...18,0 mg/100 g of soil; K2O was 8,0...25,7 mg/100 g of soil (GOST 26204-91). Observations and records were conducted according to the methodology of the State Crop Variety Test. Meteorological conditions in 2017-2019 varied considerably from the mean annual values. As a result of the analysis of the presented 23 genotypes winter hardiness of oregano in the first year of life is 68...100 %, and in the second year of life 94...97 %. Genotype T-3 has high winter hardiness, while its losses during wintering were recorded only in the second year of life at 3%. The greatest number of rooted plants was recorded for genotypes K-1 (94 %), M-2 (93 %), K-2 (93 %), which was 8...9 % higher than the standard variety. The high level of plant survival was established in genotypes before wintering in the second year of life and in the spring of the third year of life and amounted to 94...97 %

Resistance of oats to smut diseases in the forest-steppes of the Pre-Ob region

Loose smut (Ustilago avenae (Pers.) Jens.) and covered smut (Ustilago kolleri Wille) are considered to be the most harmful and widespread in the forest-steppes of the Pre-Ob region. The poor grain yields in some years could reach up to 25%, and up to 50% in the years of epiphytoties. The purpose of the current study was to identify the resistance of oat varieties to dusty and covered smut in the forest-steppes of the Pre-Ob region. The study was carried out at the phytopathological plot of the laboratory for plant gene pool of the SRIPCB, the branch of Institute of Cytology and Genetics, Siberian Branch of RAS in 2018–2021. The objects of research were Russian varieties from the world collection of VIR named after V.I. Vavilov. There have been studied 64 oat genotypes for resistance to local populations of loose and covered smut. There has been established a significant correlation between plants’ damage caused by loose and covered smut and soil temperature during the period ‘third decade of May – the first decade of June’ (r = 0.76 and r = 0.73). There was no significant correlation between plants’ damage and the average daily air temperature (r = 0.32 and r = 0.48). There has been determined a negative relationship (r = –0.77 and r = –0.71) between the manifestation of the disease and the amount of precipitation during the period ‘sowing-sprouts’. There has been established that most varieties are susceptible to pathogens. According to smut fungi resistance under conditions of an artificial infectious background, there have been identified such oat varieties as ‘Sibirsky Gerkules’, ‘Fakel’, ‘Rysak’ and ‘Uralets’. These varieties are characterized by large productivity, 1000-grain weight, resistance to lodging.

The Influence of Hydrogeological Factors on the Railway Stability in the Areas of Island Permafrost Distribution (by the Example of the Trans-Baikal Railway, Russia)

Changes in the geocryological situation at the road base and in the adjacent territory should be predicted based on an analysis of regional features of the “climate – landscape – cryolithozone – construction” system. These relationships are manifested in various ways across various cryolithozone regions, with these differences being rather poorly understood. In this regard, in 2019, the Melnikov Permafrost Institute (Yakutsk, Russia) and the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences signed an agreement on joint research work in order to elucidate the evolution of frozen soils, as well as to justify the application of certain measures to stabilise the permafrost environment. These projects aim to study the cryolithozone response along the routes of projected high-speed highways and existing railway tracks. Since 2019, the Institutes’ representatives along with specialists from the Tynda permafrost station (the branch of Russian Railways), North-Eastern Federal University (Neryungri, Russia), Zabtransproekt (Chita, Russia) and the Institute of Natural Resources, Ecology and Cryology of the Siberian Branch of RAS (Chita, Russia) have been investigating individual sections of the Far Eastern and Trans-Baikal railways in Russia. Some areas here are characterised by the continuous distribution of permafrost soils, while others – by island permafrost distribution. These areas share such common features, as the significant lifetime of linear structures (lasting for several tens of years) and the presence of deformations of the railway track, which appeared in the first years after construction. Railway track sections installed in high-temperature frozen soils are of particular interest for monitoring. However, the construction deformations are not always caused by frozen soil degradation. This article presents the results of surveys at one of such objects – a section of the track confined to the Chernovskaya station of the Trans-Baikal railway.

History of library websites

The history of foreign and Russian libraries’ websites in 1996—2017 is analyzed on the basis of professional publications and web-archive. The author analyzed the websites of Russian libraries, i. e. RASL Library for Natural Sciences, All-Russia Library for Foreign Literature, Russian State Library, Russian National Library, State National Pedagogical Library, Russian National Public Library for Science and Technology, Central Scientific Medical Library, State Public Scientific and Technological Library of the RAS Siberian Branch and divisions, Central Scientific Agricultural Library, Russian Academy of Sciences Library, Far Eastern State Scientific Library, Nizhny Novgorod Regional Universal Scientific Library, Novosibirsk State Regional Scientific Library. The number of websites was limited due to many changed domain names which disables the analysis. The archive copies of the selected libraries’ home pages obtained through the Wayback Machine service were analyzed. The first (1996–1998) home pages of Russian and foreign libraries are compared and distinctions are identified. The dynamics of Russian libraries’ websites up to 2017 is characterized. The author concludes that the libraries have been regularly changing design, content, representation forms, and navigation and retrieval systems, which is often not welcome by their users. The libraries have to introduce and promote efficiently their content and resources with the focus on user friendliness. Internet technologies and libraries’ representing themselves on the World Wide Web have changed library practice, and the libraries have to think over how to design the website and how to assess it.

Baikal glacier system, new findings

Three glaciers and other small glacial formations, which are not mentioned in the USSR Catalog of glaciers as well as in any published article, were found in the area of the Verkhneangarsky (upper Angara) Range on satellite images. Earlier, researchers from the Institute of Geography of Siberian Branch of RAS described a group of glaciers on the Baikal Mountains and the Barguzin Range, which together with the above group of the Verkhneangarsky Range are related to the Baikal basin by the climate conditions. Ogdynda-Maskit Glacier has been described on the spot in 2017, while other glaciers and snow patches are to be investigated in situ in 2018. Together with the above Baikal and Barguzin glaciers, new data allow identification of the Baikal Glacial system. The article presents analysis of climate changes in the region. Trends in mean annual temperature range from 1 to 4 °C/50 years, while the same of summer temperatures change from 1 to 3 °C/50 years, but without any evident spatial distribution between them. Another situation takes place in the spatial distribution of precipitation: trends in total precipitation decrease towards the Baikal Lake, while precipitation of the cold period, on the contrary, slightly increases towards the Lake, but with rather small trend – 10–40 mm per 50 years. The last fact confirms the influence of the Baikal basin on the alimentation of glaciers and snow patches on the Verkhneangarsky Range. Currently, glaciers of the Verkhneangarsky Range undergo a slow regression.

Applying bibliometric methods to analyze relation between available information resources and scientists’ publication activity

Within the “academic library – researcher/professional” pair, the library has to know what resources it has to obtain to meet information and document needs of users; while the researcher want to know in which journal, primarily foreign one, they should publish their research findings. The authors analyze the correlation between the journals that the library provide in various modes and those where the researcher publish their works. They examine the possibility for applying bibliometrical methods to analyze this correlation. By the example of the chemical sciences, the authors investigate into the correlation between the journals in Scopus Database accessed online by RAS Siberian Branch researchers, and those where the latter publish their works, and conclude that providing resources to scientists and the researchers’ selecting journals for publishing are related not enough: users need to get information on all related journals; there is also the need for the national subscription for all journals for them to select the periodical for publications more precisely. The data cited by the authors will make the base to substantiate subscription for academic journals and to develop collection development program.

СЕЛЕКЦИЯ МЯГКОЙ ЯРОВОЙ ПШЕНИЦЫ НА УСТОЙЧИВОСТЬ К СЕПТОРИОЗУ

Septoria is one of the main pathogens that cause great harm to the production of wheat in the Northern Trans-Urals, where during epiphytotic years it reduces the absolute mass of the grain (mass 1000 grain) by 28-46% and the yield to 50% or more. The most effective method to combat the pathogen is the creation of varieties of soft spring wheat with horizontal resistance and hardiness to the pathogen. The purpose of the research: - to study an extended set of variety samples of various ecological and geographical origin and to identify yield genotypes well adapted to local conditions, with a complex of economically valuable traits. In artificially created provocative conditions and in the years of epiphytotics of septoria, evaluate genotypes for resistance to the pathogen, isolate immune forms and recommend them as sources for creating varieties resistant and hardiness to septoriosis. By accumulating additive components of horizontal immunity, create genotypes that are resistant and hardiness to the pathogen. The tasks of the study included the detection of morphological traits that counteract infection with spores of Septoria; creation and evaluation of pathogen-resistant genotypes. Studies were conducted in 2015-2018. on the basis of the Research Institute of Agriculture of Northern Trans-Ural - a branch of the Tyumen Scientific Center of the Siberian Branch of RAS. The research material is 420 variety samples of the VIR collection of various ecological and geographical origin and220 lines of competitive variety testing of local breeding. The local population of septoria was used as inoculum. As a result of research, it was revealed that horizontal stability is due to a smooth, elastic cuticule and thickened epidermis, which is typical for resistant varieties: k-64893, 64891, k-64895 (China), k-64980 and k-64976 (Canada), which is typical and for the hardiness: K-65813 (China), K-66031, K-66032, K-66033 (Switzerland). In genotypes created locally, horizontal resistance to septoria is depends on the degree and quality of pubescence of leaves and vaginas, strong wax coating on stems, leaves, ears, and thickened epidermis, which is characteristic of stable lines: Grenada, Lutescens 463 SP-2/15, Erythrospermum 314 SP-2/15 and Erythrospermum 405 SP-2/15 and five hardiness, including variety Atlanta-1. The variety Grenada is registered by the State Commission of varieties testing from 2019 to 9 regions (Ural) of the Russian Federation, Atlanta-1 since 2018 is studied in the State Commission.

Geochemistry of ice in frost mounds in the valley of the River Sentsa (Oka plateau, East Sayan)

Te authors examined the chemical composition of underground ice sampled from the frost mounds located in the loose (unconsolidated) sediments of the Sentsa River valley (Oka plateau, Eastern Sayan) with the purpose of reconstruction the formation history of these cryogenic creations. Numerous frost mounds of various sizes are mainly composed of alternating icy loams, sandy loams, and lenses of pure ice. Samples of underground ice taken in the outcrops of the river ledges and cores from wells together with samples of river and lake waters were analyzed by traditional hydrochemical techniques (methods) in the center "Geodynamics and geochronology" (Institute of the Earth's Crust of the Siberian branch of RAS, Irkutsk). It was found that the chemical composition of pure ice melts from lenses and layers of the frost mounds is hydrocarbonate calcium (HCO3 Ca, SO4-HCO3 Ca and NH4-HCO3 Ca) with mineralization of 6.5 – 15.6 mg/L, pH = 5.6÷6.1. Mineralization of melts of texture-forming ice, taken from icy ground (i.e. with fractions of enclosing loams) was much higher – from 50 to 792.5 mg/L. River and lake water is ultra-fresh with 99–132 mg/L salinity, and according to geochemical type it is hydrocarbonate calcium (HCO3 Ca). Te specifc features of chemical composition of the underground ice (high content of ammonium salts and sulfates) depend on a water-rock interaction, the presence of organic matter in the loose (unconsolidated) sediments and a repeated volcanic activity in the late Pleistocene–Holocene. Te frost mounds are confned to a lacustrine sediments area in the backwater zone that was formed by the Late Pleistocene terminal moraine. Teir formation in the Holocene took place as a result of segregational ice formation during freezing of water-saturated lake sediments, and, presumably, repeated injections of underground waters of the under-channel and floodplain aquifers hydraulically connected with river waters. Tus, the genesis of the studied frost mounds is probably a mixed segregation-injection process.

ИСПОЛЬЗОВАНИЕ КОМПЛЕКСНЫХ ДОБАВОК ИЗ ПРИРОДНОГО СЫРЬЯ ПРИ РАЗРАБОТКЕ РЕЦЕПТУР ХЛЕБОБУЛОЧНЫХ ИЗДЕЛИЙ

This paper investigates the possibility of using dry demineralized milk whey, eggshell powder and rowanberry puree in the production of bakery products for dietary nutrition. The formulations of new bakery products based on these natural additives, their quality indicators and technologies for their production were developed at the Department of Technology and Organization of Food Production in the Novosibirsk State Technical University. In collaboration with the Laboratory of Biochemistry in the Siberian Federal Research Centre for Agrobiotechnology, the chemical composition of these additives was determined. Eggshells were processed into a fine powder at the Laboratory of the Institute of Solid State Chemistry and Mechanochemistry of the RAS Siberian Branch. The optimal ratio of ingredients in the bakery product formulations was determined by mathematical modelling. The finished products were investigated according to their organoleptic and physicochemical parameters. It is established that the addition of dry demineralized milk whey, eggshell powder and rowanberry puree into the recipes of bakery products can improve the organoleptic characteristics of the latter, thus increasing their nutritional value. In addition, these additives can be used for the development of new functional food products enriched in calcium, proteins and β-carotene with increased antioxidant activity.

Bibliometric analysis of the flow of publications by Novosibirsk State University in collaboration with the RAS Siberian Branch

Novosibirsk National Research State University is one of Russia’s most intensively developing higher education institutions, demonstrating the highest growth rates of publishing activity. This is largely due to the university’s participation in the Program of Improving the Competitiveness of Leading Russian Higher Education Establishments (Project 5–100) and is explained by the close scientific interaction with organizations Siberian Branch of the Russian Academy of Sciences.
