Authors: Gafurova Polina , Elizarov Alexander , Lipachev Evgeny Konstantinovich
Published: June 2020

A number of problems related to the construction of the metadata factory of the digital mathematical library Lobachevskii-DML have been solved. By metadata factory we mean a system of interconnected software tools aimed at creating, processing, storing and managing metadata of digital library objects and allowing integrating created electronic collections into aggregating digital scientific libraries. In order to select the optimal such software tools from existing ones and their modernization:we discussed the features of the presentation of the metadata of documents of various electronic collections related both to the formats used and to changes in the composition and completeness of the set of metadata throughout the entire publication of the corresponding scientific journal;we presented and characterized software tools for managing scientific content and methods for organizing automated integration of repositories of mathematical documents with other information systems;we discussed such an important function of the digital library metadata factory as the normalization of metadata in accordance with the formats of other aggregating libraries.As a result of the development of the metadata factory of the digital mathematical library Lobachevskii-DML, we proposed a system of services for the automated generation of metadata for electronic mathematical collections; we have developed an xml metadata presentation language based on the Journal Archiving and Interchange Tag Suite (NISO JATS); we have created software tools for normalizing metadata of electronic collections of scientific documents in formats developed by international organizations – aggregators of resources in mathematics and Computer Science; we have developed an algorithm for converting metadata to oai_dc format and generating the archive structure for import into DSpace digital storage; we have proposed and implemented methods for integrating electronic mathematical collections of Kazan University into domestic and foreign digital mathematical libraries.
Russian Scientific Publication — 2019
Authors: Gorbunov-Posadov Mikhail Mikhailovich
Published: June 2020

The article presents the events that took place last year in the world of Russian scientific publications. There is a slow slide towards paid access of some academic journals turned in open access in 2018. The European Union has announced plan "S" for the mass transition of scientific journals to open access. New models of the scientific publication are introducing. Reporting on publications requested by the Ministry of education and science in 2019 does not take into account the size of the readership of the article. Neither the Ministry of education and science, nor the Higher Attestation Commission (HAC) does not encourage publication in the public domain. In Russian Science Citation Index began the fight against widespread fraudulent trade in references to the article, but the HAC is not interested in this activity. A proliferation of contradictory the term "self-plagiarism" has spread. This label is widely stigmatized authors and journals for repeated publications.
Strong and Weak Relations in the Academic Web
Authors: Pechnikov Andrey Anatolievich
Published: June 2020

The web graph is the most popular model of real Web fragments used in Web science. The study of communities in the web graph contributes to a better understanding of the organization of the fragment of the Web and the processes occurring in it. It is proposed to allocate a communication graph in a web graph containing only those vertices (and arcs between them) that have counter arcs, and in it to investigate the problem of splitting into communities. By analogy with social studies, connections realized through edges in a communication graph are proposed to be called "strong" and all others "weak". Thematic communities with meaningful interpretations are built on strong connections. At the same time, weak links facilitate communication between sites that do not have common features in the field of activity, geography, subordination, etc., and basically preserve the coherence of the fragments of the Web even in the absence of strong links. Experiments conducted for a fragment of the scientific and educational Web of Russia show the possibility of meaningful interpretation of the results and the prospects of such an approach.

Published: June 2020

We describe the implementation of the monitoring for the IT systems at the core of the autonomous driving vehicle. The role of the monitoring is to assist in decision to start the driving cycle and continuous assessment for the fitness to drive the vehicle. The requirements for the monitoring system with the increased resiliency and data replication make it sufficiently different from standard monitoring systems and warrant a unique implementation tuned for the autonomous driving requirements. The monitoring system combines the OS events and real-time measurements of sensor data. The information is stored in flat files for emergency access as well as in a Time Series Data Base (TSDB).
Application of Supercomputer Technologies for Long-Term Modeling of Permafrost Boundaries in the Oil and Gas Fields of the Arctic
Authors: Filimonov Mikhail Yurievich , Vaganova Nataliia Anatolyevna , Akimova Elena Nikolaevna , Misilov Vladimir Evgenevich
Published: June 2020

A model of propagation of thermal fields in permafrost from various engineering objects operating in Arctic regions is considered. The proposed model includes the most significant technical and climatic parameters affecting the formation of thermal fields in the surface layer of the soil. The main objective of the study is a long-term forecasting of changes in the dynamics of permafrost boundaries during operation of cluster sites of northern oil and gas fields. Such a forecast is obtained by simulation of complex system consisting of heat or cold sources and frozen soil, thawing of which can lead to the loss of the bearing capacity and possible technogenic and environmental accidents. For example, the sources of heat can be production wells, and the sources of cold can be seasonal cooling devices that are used to stabilize the soil. To minimize the impact of heat sources on permafrost, various options for thermal insulation are used, and to preserve the original temperature regime of the top layer of soil, riprap materials consisting of sand, concrete, foam concrete, or other heat insulating material are used. The developed set of programs was used in the design of 12 northern oil and gas fields. To solve the described problem in a complex three-dimensional area, substantial computational resources are required. The computing time of one variant can often exceed 10–20 hours of machine time on a supercomputer. To speed up the numerical calculations, multi-core processors are used. Numerical calculations illustrate the possibility of a developed set of programs for making long-term forecasts for determining changes in the boundaries of the permafrost zones, and show that on multi-core processors it is possible to achieve acceleration close to the theoretical one.

Authors: LEMENKOVA Polina
Published: June 2020

The study is geographically focused on the Manila Trench, located in the west Pacific Ocean, South China Sea, west Philippines. The research aims at the geological mapping, analysis and visualizing variations in the submarine geomorphology of the Manila Trench. Technically, the work was done using Generic Mapping Tools scripting toolset (GMT). A combination of various GMT modules was applied for geospatial modelling. Methodology includes cartographic data integration and interpretation through approaches of data analysis: topographic plotting, geophysical modelling, geological mapping and statistical analysis. The data included SRTM, ETOPO1, geoid and gravity grids (CryoSat-2, Jason-1). Two sets of the cross-section profiles of the trench were automatically digitized. The profile transects were compared and differences in the geomorphic shape in southern and northern parts revealed. Southern part has steeper slope on the western part. Northern part is steeper on the continental slope part. The submarine terraces are located on the northern segment at depths -2,000 m. The depth and geomorphology of the slope vary for the range -3,500 to -4,500 m: minimals for the northern part with 526 samples (18.2%) for the depths -4,000 to -4,200 m. The histogram for the northern part has bimodal distribution with two peaks. The southern part shows 142 values for the minimals -3,500 to -3400 m. The statistical analyses revealed that northern part of the trench is deeper. The GMT functionality shown in this paper enabled integration and interpretation of the multi-source data: automatically digitized profiles, geological mapping, 2D and 3D bathymetric modelling, statistical analysis, mathematical approximation of the trend modelling. The GMT proved to be capable of visualizing geodata that can significantly improve Earth studies and interpretation of submarine geomorphology of the oceanic trenches through the advanced data analysis.

Compartir la mesa. Diseño centrado en personas para recursos museográficos educativos
Authors: Zepeda Arias Nayeli
Published: June 2020

El diseño de recursos educativos para el museo es un proceso de mediación, y como tal, su mayor consideración son las personas. ¿Cómo po­demos conectar con nuestros visitantes? ¿Cómo descifrar sus razones de sig­nificación? ¿Cómo integrar la participación y presencia de los usuarios en el desarrollo de esa mediación? El museo del siglo XXI se configura a partir de vínculos resilientes con sus visitantes y comunidad, y en la expansión de su ejercicio no considera únicamente su propia disciplina; por lo que podemos desarrollar acercamientos que, haciendo de la investigación, la empatía y el apoyo mutuo un hábito, concreten las intenciones comunicativas del museo y las necesidades de sus usuarios de forma significativa. En este texto se plan­tea el diseño centrado en personas como una estrategia para compartir la mesa con los visitantes, conocer lo que piensan, sienten y hacen, y establecer procesos colaborativos en la construcción del museo. En esta mesa, todos so­mos capaces de aprehender y aportar, por lo que se requiere de responsabili­dad para reaprender y construir

Taxonomia dos tipos de tendências: uma proposta concisa
Authors: Queiroz Campos Amanda
Published: June 2020

A palavra tendência teve uso extensivo e sofre associações forçosas, sendo usada como justificativa ou qualificação de produtos e serviços dos mais diversos fins. Além disso, aplica-se uma gama de taxonomias dentro do escopo semântico da palavra, o que compromete seu entendimento e estudo. O objetivo deste trabalho foi reduzir a complexidade sobre o conceito de ten­dência e normatizar suas terminologias. A pesquisa realizada teve natureza qualitativa e abordagem analítica. A metodologia decorreu das pesquisas bi­bliográfica e comparativa, relacionando dados de diferentes autores sobre as taxonomias que aplicavam para caracterizar diferentes tipologias de ten­dências. Aplicando a codificação axial (Grounded Theory), pode-se reduzir a quantidade de termos em dois: macrotendências e microtendências. Macro­tendências correspondem a tendências socioculturais amplas, tendo longa duração e alto impacto. Microtendências são menos duradoras e impactan­tes, atingem apenas alguns segmentos do mercado ao apresentar orientações para produtos e serviços.

The power fight is an incessant topic in Rosario Castellanos’s narrative; here we consider it within the framework of the moral values of his time and society in Mexico (los Altos de Chiapas, 1935-45). The implicit axiological crisis permits us identify problems as: the rights to express the sexuality, the existence of a moral hierarchy inside the diverse social groups, and the complexities to interact between people who live in city and indigenous people. The latency of a social problem it’s a starting point for the narrator to investigate the techniques used by the characters to preserve and/or deal their rights.
The Anti-Diary
Authors: Marinho Maria de Fátima
Published: June 2020

To include a book in a certain genre implies that it conforms to previously determined discursive constants. The originality of the work of Teolinda Gersão resides precisely in its radical break with a genre of long-standing traditions and, at the same time, in its explicit reference to a necessarily codified universe. If we are able to overcome the feeling of strangeness conveyed by the lack of obligatory markers (such as the absence of years or months), the construction of a fragmented discourse, sinuous even, gains relevance, and we can detect undeniable indicators of femininity. Life writing that escapes the canon without however forgetting the flow and/or obsessions of a saying of the mind, Teolinda Gersão’s anti-diary is undoubtedly an example of a feminine trend marked by heterodoxy and transgression.
Irreverent Views of Natália Correia and Hilda Hilst from an Autobiographical Perspective
Authors: Martins Dias Maria Heloisa
Published: June 2020

This article explores two talented, controversial writers. One Portuguese, the other Brazilian, both fueled by irreverence and provocation in the way they focus on themselves and the world. Natália Correia, a poet, novelist and Azorean playwright (1923-93), whose work emerged in the midst of the Salazar regime, and with a militant political-literary performance with other leading figures in Portuguese culture and literature during the 1950s and 1960s. Her poetry maintains affinities with aesthetic tendencies of Surrealism, although she was not a strict follower of any literary movement. Hilda Hilst, a poet, prose and playwright from São Paulo (1930-2004), was a militant of different nature. She was not linked to any aesthetic programs or literary trends, a singularity that even today defies critics.

Published: June 2020

The effect of ethanolic extract of Aristolochia indica was studied on experimentally induced nepharolithatic and urolithuasis in rats. Oxalate urolithiasis was produced by the addition of 0.75% ethylene glycol in the diet for a period for 30 days. Ethylene glycol treatment resulted in a significant increase in the levels of calcium and oxalate. Treatment of ethanolic extract of Aristolochia indica 100mg/kg body weight for 30 days revealed a dose –related effect in the reduction of lithogenic substances, following glycolic acid induced urolithiasis. Simultaneous oral treatment with at a dose of ethanolic extract of Aristolochia indica 100mg/kg for 30 days significantly reversed the ethylene glycol induced nepharolithiasis and urolithiasis. Presumably by preventing the urinary supersaturation of lithogenic substances. Especially of oxalate and calcium. These observation indicate that ethanolic extract of Aristolochia indica can play an important role in the prevention of disorders associated with kidney stone formation.

Published: June 2020

The mosquito is the principal vector of many of the vector borne diseases affecting human beings and animals. Several mosquito species vectors for the pathogens of various diseases like malaria, filariasis, Japanese encephalitis, dengue fever, dengue haemorrhagic fever and yellow fever. Repeated use of synthetic insecticides for mosquito control has disrupted natural biological control systems and led to resurgences in mosquito populations. It has also resulted in the development of resistance, undesirable effects on non-target organisms and fostered environmental and human health concern, which initiated a search for alternative control measures. Plants are considered as a rich source of bioactive chemicals and they may be an alternative source of mosquito control agents. They even result in mutation of genes and these changes become prominent only after a few generations. Hence, the present study has been choosen to determine the photochemical screening, compound identification by GC-MS studyand larvicidal activity in various concentratingof Eclipta prostrata leaves extractagainst Aedes aegypti. The phytochemicals such as saponins, tannins, phenols, terpenoids, flavanoids, amino acids and protein, carbohydrates, glycosides were identified in both aqueous and methanol extracts, further revealed that Eclipta prostrata extract exhibited significantly highest larvicidal activity in 400 ppm at 24 hrs of methanol extract when compared to aqueous extract. The GC-MS analysis, showed 16 different compoundsand the compound isopropyl myristate, is found to be present in high area percentage.Further, the result of the currentinvestigation revealed that the methanol extract of Eclipta prostrata possess good larvicidal activity against Aedes aegypti with maximum larvicidal repellent and the numbers of the dead larvae were affected by increasing the concentrations of the plant extracts.

HPTLC method for isolation, identification and quantification of quercetin from in vivo and in vitro samples of Naringi crenulata
Authors: Singh Neelam , Meena Mukesh Kumar , Patni Vidya
Published: June 2020

Naringi crenulata (Roxb.) Nicolson, is a rare medicinal plant belonging to the family Rutaceae. It is a spinous tree and has great medicinal value. During the present study a rapid, simple, accurate and specific HPTLC method for quantitative estimation of quercetin present in the dried leaf powder and callus of N. crenulata has been developed .The method used in this work resulted in good peak shape and enabled good resolution of quercetin from N. crenulata samples. Quercetin was identified in in vivo (leaf) and in vitro (six weeks old callus) tissues. Presence of isolated quercetin was further confirmed by superimposable IR spectra of isolated and authentic samples of quercetin and NMR spectra of isolated quercetin. Variation in quercetin content in in vivo and in vitro samples in N. crenulata was observed. In vivo leaf had maximum amount of quercetin (0.13%) while minimum amount was found in in vitro callus (0.032%). High content of quercetin in leaf shows its potential of synthesizing quercetin. This study is also of practical importance because flavonoid quercetin is the most active of all flavonoids. Many medicinal plants owe their activity to their high quercetin content. Several studies revealed quercetin’s significant anti-inflammatory activity due to direct inhibition of initial processes of inflammation. It also has potent antitumor and antioxidant properties including the inhibition of cancer cell proliferation and migration. This study is of practical importance because compound quercetin was firstly reported to be isolated from callus of N. crenulata
