Published: May 2021

MOFs and COFs are porous materials with a large variety of applications including gasstorage and separation. Synthesised in a modular fashion from distinct building blocks, anear in?nite number of structures can be constructed and the properties of the material canbe tailored for a speci?c application. While this modularity is a very attractive feature it alsoposes a challenge. Attempting to identify the best performing material(s) for a given appli-cation is experimentally intractable. Current research e?orts combine molecular simulationsand machine learning techniques to evaluate the simulated performance of hundreds of thou-sands of materials to identify top performing MOFs and COFs for a given application. Theseapproaches typically rely on moderated brute-force screening which is still resource-intensiveas typically between 70 - 100 % of the hundreds of thousands of materials must be simulatedto create a training set for the machine learning models used, restricting screening to rela-tively simple molecules. In this work we demonstrate our novel Bayesian mining approachto materials screening which allows 62 - 92 % of the top 100 porous materials for a range ofapplications to be readily identi?ed from large materials databases after only assessing lessthan one percent of all materials. This is a stark contrast to the 0 - 1 % achieved by conven-tional brute-force screening where porous materials are just chosen at random during a highthroughput screening. Through this accelerated virtual screening process, the identi?cation ofhigh performing materials can be used to more rapidly inform experimental e?orts and hencelead to an acceleration of the entire research and development pipeline of porous materials.

Published: May 2021

The tyrosine residue of proteins participates in a wide range of activities including enzymatic catalysis, protein-protein interaction, and protein-ligand binding. However, the functional annotation of the tyrosine residues on a large scale is still very challenging. Here, we report a novel method integrating azo coupling, bioorthogonal chemistry, and multiplexed proteomics to globally investigate the tyrosine reactivity in the human proteome. Based on the azo-coupling reaction between aryl diazonium salt and the tyrosine residue, the two different probes were evaluated, and the probe with the best performance was employed to specifically target the tyrosine residues. After the reaction, tagged tyrosine containing peptides were selectively enriched using bioorthogonal chemistry, and a small tag on the peptides from the cleavage perfectly fits for site-specific analysis by MS. Coupling with multiplexed proteomics, we quantified over 5,000 tyrosine sites in MCF7 cells and these quantified sites displayed a wide range of reactivity. The tyrosine residues with high reactivity were found on functionally and structurally diverse proteins, including those with the catalytic activity and binding property. This method can be extensively applied to advance our understanding of protein functions and facilitate the development of covalent drugs to regulate protein activity.
Enzymatic C-N Bond Formation via Aerobic Nitroso Ene Reactions
Authors: Deska Jan , Jäger Christina
Published: May 2021

A novel biocatalytic protocol enables the direct and selective introduction of nitrogen functionalities via activation of allylic C-H bonds. Utilizing an oxidase/peroxidase couple for the formal dehydrogenation of N-hydroxycarbamates and hydroxamic acids with air as terminal oxidant, acylnitroso species are generated under particularly mild aqueous conditions. The reactive intermediates undergo C-N bond formation through an ene-type mechanism and provide high yields both in intramolecular and intermolecular enzymatic aminations. Investigations on alternative reaction pathways and labelling studies provide more insights into this unprecedented biocatalytic promiscuity of classical oxidoreductases as catalysts for nitroso ene-based transformations.
Analysis of decayed Norway spruce wood impregnated with CCB after 14 years of outdoor exposure
Authors: Humar Miha , Lesar Boštjan , Kržišnik Davor , Balzano Angela
Published: May 2021

Wood in outdoor applications is exposed to abiotic and biotic factors. If we want to slow down the decay, the wood must be protected. In the past, biocidal products based on copper, chromium, and boron compounds (CCB) were one of the most important solutions for wood protection under extreme conditions. Although CCB is in practice no longer used in the EU, it can serve as a reference for the evaluation of new biocidal products. At the field test site of the Department of Wood Science and Technology, Biotechnical Faculty, an experiment has been carried out under real conditions for 14 years, in which impregnated samples are exposed to the weather according to a double-layer test. In the case of treated wood, we often find that the wood decays faster than expected. In this work we want to determine what contributes to decay based on the analysis of decayed impregnated wood from the field test site. The results show that sufficient retention and penetration of the active substances into the wood ensures the planned service life.

Varieties of Video Lectures
Authors: Каспаринский Феликс Освальдович
Published: May 2021

The article is devoted to the typology of the main variants of video lectures (https://vimeo.com/showcase/6184718), which differ in didactic value and laboriousness of creation. For each option of video lectures, the key conditions for effective formation and use are determined. Particular attention is paid to the optimization of hardware for the creation of various options for video lectures in full-time and distance learning.
As a basic option, a video recording of a PowerPoint presentation with speech and graphic comments on the slides is considered. The screen (electronic board) videorecording on the left with the lecturer in profile, named ad standard profile version, is recommended for use when there is a shortage of space in the classroom. In the presence of a video camera with optics that ensure the preservation of the detail of images of visual materials, the preferred option for video lecture is a standard frontal one, filmed from the far end of the audience. Didactically optimized editing of video lectures allows you to combine high-quality recording of visual materials of the basic version with mediocre video recordings of the teacher's actions.
Integrative versions of video lectures are created by overlaying the video recording of the teacher's actions over a specially designated invariant place in the design of the slides of the basic version of the video lecture. The options for adapting the design of PowerPoint presentations to form a basic and integrative version of video lectures are proposed. The highest ratio of "didactic quality / labor costs" is achieved when creating integrative video lectures directly in the process of face-to-face and distance teaching.

The article describes a typical object-oriented WEB-system designed for storing and providing various reference and statistical data on the scientific works of employees of an institution (group of institutions), developed by specialists of the JSCC RAS. The system contains information about publications of employees and reports made by them at scientific conferences, symposiums, and seminars. The system is focused on working with objects belonged to classes connected between each other, such as "author", "organization", "publication", "report", "event". The metadata profile of objects of each class includes attributes that are necessary to get detailed information about both an individual object of this class and a group of objects associated with the specified attribute values of objects of other classes. For example, you have to get a list of articles by employees of a given organization published articles in a given journal for a given period of time. A distinctive feature of the system is the introduced concept of "equivalent" objects. Such objects are "persons" corresponding to the same author with different spellings of the last name in the bibliographic descriptions of publications; organizations with different versions of names; articles which are published without changes in different languages. This article describes in detail the features of the system, its user interface, and provides examples of performing specific queries.

Published: May 2021

Introduction Progressive ultrafiltration (UF) could improve IDH. The aim of this work was to evaluate the effectiveness of progressive UF in the management of IDH. Methods This randomized clinical trial in two groups: interventional group A (UF, n = 12) and control group B (n = 12), was conducted in chronic hemodialysis patients with IDH. A first phase of cross-sectional collection of BP before and after dialysis, during 2 weeks, made it possible to obtain this cohort of 24 patients. A progressive decrease in basal weight of 0.25 kg per session as a function of hemodynamic tolerance was achieved in group A. The primary endpoint, the proportion of patients with disappearance of IDH, was assessed at baseline end of the 4th and 8th week. Results At the 4th week, the IDH disappeared in 83.3% and 41.7% of the patients of the group A and B respectively with a hazard ratio (HR) at 0.29; IC 95 = [0.14-0.59]; p = 0.035. At the 8th week, the IDH was missing in 72.7% and 66.7% of the patients of the group A and B respectively with a HR at 0.76; IC 95 = [0.58-1.00]; p = 0.75. In addition, the decrease in basal weight was associated with the occurrence of side effects (p = 0.0001) with a HR of 5 [1.45-7.27]. UF discontinuation was required in 4 patients in group A (36.4%). Conclusion Progressive UF was associated with a significant reduction in the prevalence of IDH in our patients at week 4.

Authors: S Bhavithra , B Sushmitha , T Venkatesan , Sankar P. A. Gowri
Published: May 2021

LPG gas is primarily used for cooking in our country. This paper focuses on continuous monitoring, booking and leakage detection in household LPG cylinder. In this system we have used PIC 16F877A microcontroller, GSM SIM 800c module and ESP8266 for monitoring and detection purpose. If gas level goes low, it helps us to make automatic booking of new gas cylinder using GSM module. Gas level is monitored with the help of the load cell and the current level of the cylinder can be viewed at any time in our mobile phone with the help of mobile application. The gas leakage is sensed with the help of MQ-6 gas sensor. When any leakage is detected, it turns on the buzzer and also alerts the consumer through a message. An automatic closure of cylinder valve is done using a solenoid valve and exhaust fans are switched on. By detecting gas leakage, we can avoid accidents which causes damage to life and property.
inclusión, un derecho en la educación

Published: May 2021

Este trabajo expone un análisis de las políticas que sustentan la educación inclusiva en Ecuador, como un derecho de todas las personas indistintamente de su condición. La finalidad de aportar en el debate sobre el derecho de todos a acceder, permanecer y egresar exitosamente de los sistemas educativos se concreta a partir del estudio epistemológico realizado con la aplicación de los métodos: hermenéutico, analítico-sintético, histórico-lógico y holístico-dialéctico. Los resultados revelan que los acuerdos y políticas sociales en materia educativa, transcurren por los enfoques: asistencialista, clínico, integrador, hasta el actual inclusivo, centrado en la eliminación de las barreras de participación y de aprendizaje, Si bien, desde hace varias décadas existen políticas de inclusión educativa como base para la ejecución de acción inclusivas, no es menos cierto que, en los distintos niveles de educación persisten culturas y prácticas homogeneizadoras, que vulneran los derechos del estudiantado en contextos aparentemente inclusivos.
New data on the spread of the invasive species Dothistroma septosporum (Dorogin) M. Morelet in Belarus

Published: May 2021

Red band needle blight, or Dothistroma needle blight is one of the most common and harmful diseases of pine. The causative agents of the disease are pathogenic micromycetes Dothistroma septosporum (Dorogin) M. Morelet and Dothistroma pini Hulbary. Dothistroma needle blight was firstly detected in Belarus in 2012 year, but till now information about this disease in the republic is fragmentary. The article presents the results of a survey of different pine trees, carried out in the period 2016–2020 years in botanical and dendrological gardens, forest nurseries and mini-arboretums at forestry enterprises, urban stands, nurseries of decorative plants, garden centers, for the presence of Dothistroma needle blight. The species identification of the causative agent of the disease was carried out by mycological and molecular genetic methods. In this study, Dothistroma needle blight was revealed on individual trees of Pinus mugo, P. nigra and P. ponderosa in the stands of the Central Botanical Garden of the NAS of Belarus, the dendrological garden of the Glubokoe experimental forestry enterprise, in the nurseries of decorative plants in the Grodno and Minsk regions. In the collected samples of needles, the invasive species Dothistroma septosporum was identified. The frequency of occurrence of the pathogen was 4.8–7.2 %, the proportion of observation sites in which this disease was detected at 60 %. The detection of Dothistroma needle blight on pine trees, mainly on planting material imported from abroad, indicates a transboundary route of D. septosporum entering the country. Analysis of literature data indicates the potential danger of Dothistroma needle blight for pine stands in the republic, which in turn requires the organization of regular monitoring of the disease and the development of methods to limit the spread of D. septosporum in the republic.
New data on the chemical composition of the non-ferrous metal products of the X–XVIII centuries on the territory of Northern and Central Belarus
Authors: Mahalinski I. U.
Published: May 2021

The article presents the results of analysis of new data on the elemental composition of non-ferrous metal products on the territory of certain archaeological sites in Northern and Central Belarus. The author distinguishes two main stages in the non-ferrous metalworking of the region: the X–XIII centuries and XIV–XVIII centuries. It is noted that the period of the X–XIII centuries is characterized by a significant predominance of copper-zinc alloys with average and high concentrations of zinc in metal. Meanwhile, bronze alloys also play an important role, accounting for 35 % of the total number of the items studied. Samples made of copper-zinc and bronze alloys are also characterized by a significant amount of lead. As a result of the analysis of the data on the elemental composition of non-ferrous metal products of the XIV–XVIII centuries, it is concluded that non-ferrous metalworking of this period is characterized by the continuity of traditions with handicraft production of the previous period, which manifested itself in the widespread use of copper-zinc alloys, as well as of tin-lead and multicomponent bronzes. At the same time, a significant difference is the increase in the proportion of alloys with high concentrations of alloying components.
Features of transformation of soil properties of the arable land in Belarus
Authors: Lapa V. V. , Azarenok T. N.
Published: May 2021

Based on the scientific systematic multi-temporal data and the large-scale soil mapping studies, for the first time we developed a methodological approach to estimating the transformation of the composition and properties of the arable land of the Republic for a 40-year period since the publication of the scientific work “The Soil of the Byelorussian SSR” (1974). At the present stage of the soil development, the transformation of the soil properties of the arable land, involved in the agricultural usage over the 40-year period, is influenced by the cultural process of soil formation and is characterized by the “strong” transformation of the properties in relation to their natural potential: in soils on loamy soil-forming rocks, the CTS value is varied in the range of 20–28 units, on sandy loam soil-forming rocks, СTS is 18–27, and on connected sandy loam soil-forming rocks it is 18–28. According to the research results on the soils of the arable land formed on light soil-forming rocks (sandy, loose-sandy), in contrast to loamy and heavier soil-forming rocks, the transformation degree of the properties is determined as “strong” and “very strong”. The results of the studies point to a clear dependence of the transformation degree of the properties of the gum-accumulative horizons of the studied soil varieties of the granulometric composition, which reflects the specific features of the soil cover of the Republic.

Published: May 2021

In recent years, development of confectionery industry is aimed at creating products of increased nutritional value, enriched with macro- and micronutrients, for dietary and prophylactic purposes. One of the most common flour confectionery products in Russia is raw gummy gingerbread. The aim of the research is to study the impact of amaranth flour and encapsulated vegetable oil wall material on the quality of raw gummy gingerbread, development of technology and formulations for raw gingerbread. The optimal ratio of the mixture of starch and amaranth flour has been determined, amounting to 70 and 30 %, respectively. Amaranth flour showed to reduce the density of raw gingerbread to 732 kg/m3 , and moisture content increases to 14.1 % for gingerbread with BPS on IBS, and for gingerbread on BPS with whey - 743 kg/m3 , and humidity increases to 14.9 %. At the same time, organoleptic characteristics and structure of the crumb are fundamentally different from those inherent in gingerbread products: porous structure of the crumb, fragility, irregular shape, uneven color, tears on the surface of gingerbread. Direct impact of protein structural component of encapsulation in the nut oil emulsion on organoleptic indicators of the gingerbread quality (taste, color, smell, appearance, shape, surface, and others) has been revealed. It has been determined that moisture content in gingerbread cooked according to the developed formulation was 1.0-2.0 % higher and they have longer shelf life compared to traditional gingerbread. Formulations with high and low fat content and technology for production of raw gingerbread with encapsulated nut butter have been developed. The developed technology received a patent of the Russian Federation No. 2734 620 “Gingerbread with vegetable oils and milk whey”, which testifies not only to its scientific, but also practical significance.

Published: May 2021

The realization of the intellectual component is an important task in the context of the Fourth Industrial Revolution and the development of technology. The country's place on the global economic map is not least determined by the availability of resources and efficiency of their use, it can determine both the competitiveness of the economy and its opportunities in the future. Under the conditions of a market economy and the transition to a new technological system, the role of certain factors that in the previous technological systems ensured the competitiveness of the economy changes. Those that can ensure the singular development of the economy and its nonlinear progress come to the fore. First of all, it is knowledge-forming and knowledge-producing factors that can ensure innovative development and, especially, the development of fundamentally innovative products or innovative breakthroughs. This involves the intensification of investment activities in innovation, the use of broad financial and administrative tools, as well as the development of innovations in management systems and the formation of creative and innovative components of economic activity. All this, in turn, involves the formation of a holistic strategy for the development of the innovation ecosystem, which has a high efficiency of implementation given the practice of developed countries and countries that have formed their competitiveness on the basis of intelligence. The combination of such factors should facilitate the entry into the market of new competitive goods and services, which in the age of digitalization and networking will form new advantages of using existing opportunities.
