Estimation of biomass of dung beetles (Coleoptera: Scarabaeoidea) from the Russian Far East
Authors:   Federal Scientific Center of the East Asia Terrestrial Biodiversity, Far Eastern Branch of Russian Academy of Sciences, Vladivostok, Russia, Shabalin S.A.
Published: May 2023

Data on dry biomass and body length are given for 47 species of dung beetles from the southern part of the Russian Far East. The length-to-body weight relation in specimens of 47 species of dung-beetles was calculated, to enable biomass to be estimated from information about body length. Shown, the selection of optimal models of length-weight relationship of dung-beetles depends on the types of trophodynamic relationships of beetles and its size classes. When conducting ecological studies using such an indicator as dry biomass, it is necessary to determine the biomass of individual species from regional faunas, and to determine the biomass along the length of the body of beetles, it is necessary to use exclusively models built also for regional faunas.

Published: May 2023

Urinary mercapturic acids (MAs) are often used as biomarkers for monitoring human exposures to occupational and environmental xenobiotics. In this study, we developed an integrated library-guided analysis workflow using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry. This method includes expanded assignment criteria and a curated library of 220 MAs and addresses the shortcomings of previous untargeted approaches. We employed this workflow to profile MAs in the urine of 70 participants - 40 nonsmokers and 30 smokers. We found approximately 500 MA candidates in each urine sample, and 116 MAs from 63 precursors were putatively annotated. These include 29 previously unreported MAs derived mostly from alkenals and hydroxyalkenals. Levels of 68 MAs were comparable in nonsmokers and smokers, 2 MAs were higher in nonsmokers, and 46 MAs were elevated in smokers. These included MAs of polyaromatic hydrocarbons and hydroxyalkenals and those derived from toxicants present in cigarette smoke (e.g., acrolein, 1,3-butadiene, isoprene, acrylamide, benzene, and toluene). Our workflow allowed profiling of known and unreported MAs from endogenous and environmental sources, and the levels of several MAs were increased in smokers. Our method can also be expanded and applied to other exposure-wide association studies.

Metal-organic frameworks (MOFs) are porous, crystalline materials constructed from organic linkers and inorganic nodes with potential utility in gas separations, drug delivery, sensing, and catalysis. Small variations in MOF synthesis conditions can lead to a range of accessible frameworks with divergent chemical or photophysical properties. New meth-ods to controllably access phases with tailored properties would broaden the scope of MOFs that can be reliably prepared for specific applications. Herein, we demonstrate that simply increasing the reaction concentration during the solvother-mal synthesis of M2(dobdc) (M = Mg, Mn, Ni; dobdc4− = 2,5-dioxido-1,4-benzenedicarboxylate), also known as MOF-74, unexpectedly leads to trapping of a kinetic intermediate termed CORN-MOF-1 (CORN = Cornell University). In-depth spec-troscopic, crystallographic, and computational studies support that CORN-MOF-1 has a similar structure to M2(dobdc) but with partially protonated linkers and charge-balancing or coordinated formate groups in the pores. The resultant vari-ation in linker spacings causes CORN-MOF-1 (Mg) to be strongly photoluminescent in the solid state, whereas H4dobdc and Mg2(dobdc) are weakly emissive due to excimer formation. In addition, CORN-MOF-1 variants can be converted into high-quality samples of the thermodynamic M2(dobdc) phases by heating in N,N-dimethylformamide (DMF). Overall, our findings support that high-concentration synthesis provides a straightforward method to identify new kinetic MOF phas-es with different properties from known materials and to produce highly porous samples of MOFs, paving the way for the discovery and gram-scale synthesis of framework materials.
Disruption of the FMN-A524 interaction cascade and Glu513 induced collapse of the hydrophobic barrier promotes light induced Jα-helix unfolding in AsLOV2
Authors: Arshi Syeda Amna , Chauhan Manisha , Sharma Amit
Published: May 2023

The C terminal Jα-helix of the Avena Sativa’s Light Oxygen and Voltage (AsLOV2) protein, unfolds on exposure to blue light. This characteristic seeks relevance in applications related to engineering novel biological photoswitches. Using Molecular Dynamic (MD) simulations and the Markov State Modeling (MSM) approach we provide the mechanism that explains the stepwise unfolding of the Jα-helix. The unfolding was resolved into seven steps represented by the structurally distinguishable states distributed over the initiation and the post initiation phases. Wherein, the initiation phase occurs due to the collapse of the interaction cascade FMN-Q513-N492-L480-W491-Q479-V520-A524, the onset of the post initiation phase is marked by breaking of the hydrophobic interactions between the Jα-helix and the Iβ-sheet. This study indicates that the displacement of N492 out of the FMN binding pocket, not necessarily requiring Q513, is essential for the initiation of the Jα-helix unfolding. Rather, the structural reorientation of Q513 activates the protein to cross the hydrophobic barrier and enter the post initiation phase. Similarly, the structural deviations in N482, rather than its integral role in unfolding, could enhance the unfolding rates. Further, the MSM studies on the wild type and the Q513 mutant, provide the spatio-temporal roadmap that layout the possible pathways of structural transition between the dark and the light states of the protein. Overall, the study provides insights useful to enhance the performance of AsLOV2 based photoswitches.
Activating Ru in the pyramidal sites of Ru2P-type structures with earth-abundant transition-metals for achieving extremely high HER activity while minimizing noble metal content

Published: May 2023

Rational design of efficient pH-universal hydrogen evolution reaction (HER) catalysts to enable large-scale hydrogen production via electrochemical water splitting is of great significance, yet a challenging task. Herein, Ru atoms in the Ru2P structure were replaced with M=Co, Ni, or Mo to produce M2-xRuxP nanocrystals. The metals show strong site preference, with Co and Ni occupying the tetrahedral sites and Ru the square pyramidal sites of the CoRuP and NiRuP Ru2P-type structures. The presence of Co or Ni in the tetrahedral sites leads to charge redistribution for Ru and, according to density functional theory (DFT) calculations, to a significant increase in the Ru d-band centers. As a result, the intrinsic activity of CoRuP and 1 NiRuP increases considerably compared to Ru2P in both acidic and alkaline media. The effect is not observed for MoRuP, in which Mo prefers to occupy the pyramidal sites. In particular, CoRuP shows state-of-the-art activity, outperforming Ru2P with Pt-like activity in 0.5 M H2SO4 (η10=12.3 mV; η100=52 mV; turnover frequency (TOF)=4.7 s-1). It remains extraordinarily active in alkaline conditions (η10=12.9 mV; η100=43.5 mV) with a TOF of 4.5 s-1, which is 4x higher than that of Ru2P and 10x that of Pt/C. Further increase of the Co content does not lead to drastic loss of activity, especially in alkaline medium, where for example the TOF of Co1.9Ru0.1P remains comparable to that of Ru2P and higher than Pt/C, highlighting the viability of the adopted approach to prepare cost efficient catalysts.
Rheological profiles of DNA extracts from forensic bloodstain samples
Authors: Elliott Colin , Stotesbury Theresa
Published: May 2023

Rheology can be used to probe the differences in physical properties and in-solution behaviours of synthetic and biological polymers, like deoxyribonucleic acid (DNA). Large fragments of highly concentrated genomic and phage DNA have been characterized using rheology; however, this amount and size of DNA are atypical in DNA extracted from forensic evidence. To determine the applicability of rheology for the analysis of dilute concentrations of short DNA fragments expected from forensic specimens (low molecular weight DNA at concentrations in the ng/µL range), we conducted an optimization experiment in which we varied the size, concentration, and conformation of synthetic DNA in various solvents and polymer matrices. We found that incorporating DNA into an alginate-based, ionically crosslinked hydrogel produced the greatest differences in rheological profiles from synthetic DNA comprised of different physical properties. The conformation and size of encapsulated DNA provided significantly different responses during dynamic oscillatory measurements (p<0.05). Additionally, a time since deposition (TSD) study was performed using rotational and oscillatory tests to understand the changes in DNA extracts from bloodstains left to degrade for up to 19 months. DNA extracted from all timepoints could be detected and quantified for the tested temperature conditions (-20°C, 4°C, 22°C). Statistical analyses revealed moderate correlations between the rheological responses of DNA-containing materials and TSD (r = -0.57 to r = 0.62). Our results highlight the viability of rheology as a technique for the analysis of dilute DNA oligos and DNA extracts, and as a complementary technique for the determination of bloodstain TSD.
Probing the Formation of Cathode-Electrolyte Interface on Lithium Iron Phosphate Cathodes via In Operando Mechanical Measurements

Published: May 2023

Interfacial instabilities in electrodes control the performance and lifetime of Li-ion batteries. While the formation of solid-electrolyte interface (SEI) on anodes has received much attention, there is still lack of understanding about the formation of cathode-electrolyte interface (CEI) on the cathodes. To fill this gap, we report on dynamic deformations on lithium iron phosphate, LiFePO4 cathodes during charge / discharge by utilizing in-operando digital image correlation, impedance spectroscopy and Cryo X-ray photoelectron spectroscopy. LiFePO4 cathodes were cycled in either LiPF6, LiClO4 or LiTFSI- containing organic liquid electrolytes. Beyond the first cycle, Li-ion intercalation results in a nearly linear correlation between electrochemical strains and the state of (dis)-charge, regardless of the electrolyte chemistry. However, during the first charge in LiPF6 - containing electrolyte, there is a distinct irreversible positive strain evolution at the onset of anodic current rise as well as current decay at around 4.0V. Impedance studies show the increase in surface resistance in the same potential window, suggesting the formation of CEI layers on the cathode. The chemistry of the CEI layer was characterized by X-ray photoelectron spectroscopy. LiF is detected in CEI layer starting as early as 3.4 V and LixPOyFz appeared at voltages higher than 4.0 V during the first charge. Our approach offers new insights into the formation mechanism of CEI layers on the cathode electrodes, which is crucial for the development of robust cathode and electrolyte chemistries for higher performance batteries.

Conceptual assessment of the fuel efficiency of passenger aircraft with the transition to composite wings
Authors: Kretov A. S. , Tinyakov D. V. , Shataev P. A.
Published: May 2023

One of the success indicators for any new aircraft is its fuel efficiency, influencing both range and cost-effectiveness, as fuel costs amount to 30% of direct operating costs. Based on the analysis of take-off mass response to design changes, a solution to the basic-type aircraft improvement in terms of fuel efficiency is considered. The feature of proposed redesigning is the use of a higher aspect- ratio of an airfoil allowing for fuel efficiency to be increased by reducing the induced drag. Two solutions are considered to substantiate this approach. The first one is the transition to composite wing structures, which will allow for a high aspect ratio of an airfoil without losing rigidity. The second one is the application (if necessary) of devices, reducing the wingspan, caused by the airport restrictions. The methodology for assessing the mass of composite wings based on the universal weight formula by V.A. Komarov which was specified by applying an integral factor considering the features of mass distribution in the structure, the structural adaptation of structure elements and their strength performance, has been proposed. To simplify the arrangement of aircraft with large-span wings in the available airport layout, the application of folding wingtips was considered. The principal analysis of the wingtip swiveling unit structure was performed. The assessment of the folding device effect upon the mass of a passenger aircraft was completed. The proposed approach was verified based on the Boeing company of B777 aircraft family. The numerical analysis of the composite wing application for the IL-96, Tu-214 and SSJ-100 was performed, and the winglet use effect on the MC-21 aircraft was studied.
Exploring Reading Strategies Used by Students Based on Metacognitive Awareness
Authors: Nisrina Nisrina
Published: May 2023

The crucial impact of knowing about learners reading strategies to acquire a second language has been widely accepted. Therefore, this paper reports a study investigating university students' awareness of their reading strategies when they read English academic texts. As many as 39 first-year university students took part as the research subject, and they answered a 30-item questionnaire on reading strategies. A four-point Likert Scale questionnaire named SORS (Survey of Reading Strategies) was deployed to collect the data concerning the use of reading strategies. The results indicated that among the three reading strategies, the students tended to use Problem-solving strategies more, followed by the Global Reading Strategies and Support Reading Strategies. Finally, the idea of metacognitive that undergoes before, during, and after reading activities must be equipped by the teachers to fulfil the scarcity in those stages of reading. The findings showed that the mean score of each category varied among the three, and these were discussed considering the reading strategy knowledge base as well as the theoretical and practical implications.

Authors: Yelizarova Olena , Hozak Svitlana , Diuba Nataliya , Stankevych Tеtiana , Parats Alla
Published: May 2023

Introduction. The COVID-19 pandemic including social isolation was a stress trigger for adaptation systems in different population groups. Therefore, the study of these processes is relevant. Since the lack of communication is one of the risk factors the non-communicable diseases, as well as mental health disorders, and this relationship is bidirectional, the purpose of our study was to study the impact of social communication of school-age children with different metabolic statuses on their mental health during adaptation to the effects of stress factors. Materials and methods. The anthropometric indicators and characteristics of communication of 114 school children (56 boys, 58 girls, average age 12.3±0.2 years) were studied. Informed consent was obtained from the parents. The weekly survey of the anxiety-depressive signs (TDS) was conducted using the RCADS-P-25 questionnaire during the 5 weeks after the lockdown lifted. ANOVA, crosstabulation tables, and a multiple linear regression model were used to determine the relationships between variables. The STATISTICA 8.0 program was used for statistical analysis. Results. Among school-age children of the surveyed cohort, the proportion of overweight and obese children was 26.3±4.1 %. 34.6±4.7 % of students had communication difficulties with their peers. It was established that overweight and obese children had significantly higher TDS levels than the normal-weight group throughout the study (F=10.9; p<0.001). It was determined that TDS values were significantly higher in the group of children who had difficulties with "live" communication with peers (F=17.6; p<0.001). The highest values of TDS were determined in children who communicated in social networks for 4 hours or more or did not communicate at all, and the lowest indicators were found in children who communicated for 1-2 hours a day (F=9.6; p<0.001). There was no statistically significant influence of the frequency of communication in social networks on TDP values (p>0.6). Conclusions. Communication in social networks with peers lasting 1-2 hours was a favorable adaptation factor in this study, while "live" communication difficulties and overweight/obese were unfavorable, which requires additional study. It is necessary to develop both the communication skills of school-age children and the culture of communication in social networks.

The object of this study is the migration of the Russian-speaking population from the former Soviet Union to three Central and Eastern European countries-Hungary, the Czech Republic and Austria. The subject of the study was the process of adaptation of Russian-speaking migrants from the former Soviet Union through the channel of entrepreneurship and investment in three countries. The stages of migration of the Russian-speaking population to Hungary, the Czech Republic and Austria from the 1960s to the present are highlighted. Interviews were conducted with post-Soviet migrant entrepreneurs, their acquaintances, and experts. The most illustrative examples of the relationship between business activity and the immigration process in the three host countries are analyzed. Based on in-depth interviews with Russian-speaking migrant entrepreneurs, the idea of post-Soviet investments in the EU economy as “spare airfields” in Hungary, the Czech Republic and Austria was confirmed. Foreign investments of citizens of the former Soviet Union in business abroad or its creation from scratch, often serve to protect the earned funds from the unstable economic and legal environment of sending countries. Post-Soviet Russian enterprise on the one hand, serves the purposes of obtaining documents for residence in the host EU countries and way of life support; and on the other hand, confirms the theory of investments of nationals of developing countries to the advanced economies with the aim of social integration in the host societies. Examples of post-Soviet Russian-language entrepreneurship have shown that entrepreneurship in the construction sector in Hungary and the Czech Republic, hotel business and human resources services in Austria, are the main focus of these countries ‘ economies rather than ethnic businesses. At the second stage, the legislation of the three countries concerning the grounds for obtaining long-term residence of migrants from the former Soviet Union was studied.

Since the early 1980s, the need for collaboration between companies has intensified, in particular due to the increasing complexity of products, the accelerating pace of innovation and technology diffusion, and the expansion of investments and knowledge areas required for their development. Unlike a market transaction, a partnership is created when the customer and suppliers agree to share risks and responsibilities in developing and implementing a feature or subset of a complex product, coordinating their skills and resources. As for cooperation with a supplier in conditions of moderate intensity of competition, then, more often, this is due to the fact that in this context the need for resources and the required innovations is not so high. Collaboration strategies are an attractive way to manage resources when the firm’s capabilities are insufficient to achieve the desired result.The paper notes that the intensity of competition favors horizontal cooperation strategies, but does not encourage the choice of vertical cooperation. It has been proven that the ideas of horizontal collaboration are formed during research and development, development of new products and improvement of existing technologies. In this context, they turn out to be the main source of radical innovation. This type of cooperation provides access to the resources most needed to compete in the market.

The necessity of rethinking the prospects for social and labor development in the context of the formation of a new (digital, network) economy is proved. The argumentation of the new opportunities that the new economy opens up for a working person, and the restrictions and threats caused by large-scale multi-vector changes in the present, is given. The necessity of changing the theoretical, philosophical understanding of reality — technical and technological, economic and social and labor — is substantiated. The authors tried to look into the future of the world of work. The main concept defended by the authors is that information and communication, digital and other breakthrough technologies of «Industry 4.0» determine the establishment of both a new format of globalization and a global social division of labor, and a new platform for social and labor development. In a more generalized interpretation, the purpose of the article is to streamline existing and form modern ideas about the nature of transformations and trends in the development of the world of work during the onset of the next stages of globalization and the formation of a new economy. The essence of today’s phenomena that determine the development of a new platform for social and labor development in the first decades of the 21st century is revealed. In the author’s mental model of modern social and labor development, globalization and the new economy in their social and labor dimension are dominant.

This article considers the effect of Marx’s law of correspondence of production relations to the nature and level of development of productive forces in the context of modernity. It proves that this law has shown its scientific validity and retains its relevance in the conditions of the Fourth Industrial Revolution (the sixth technological mode, the sixth information revolution). In modern terminology, digital technological tools, associated primarily with artificial intelligence and cognitive technologies, as well as the Internet of Things, global industrial networks, nano- and biotechnologies, genetic engineering, etc., act as productive forces. Economic (production) relations are represented by social and labour relations, which are specific in the new wave of innovation, characterized by the widespread use of forms of part-time and non-standard employment, the blurring of boundaries between work and leisure, the leveling of differences between workers and employers, producers and consumers, giving the labour market a mobile, but unstable character, and eroding the foundation of the social structure of society. The contradiction between productive forces and production relations can be resolved through the occurrence of a certain turning point, which has a revolutionary character. The article shows that the modern world is at the point of technological singularity, the exit from which can be found in the path of civilizational movement along one of two options: either cybertyranny or cyberdemocracy. Examples are given to demonstrate the danger of technological risks associated with the negative impact of Industry 4.0 in the form of cyber tyranny. The ethical implications of digital technologies that are not socially neutral depend directly on the intentions of the actors using them.

The aim of this research was to construct a teaching model that was intended as a standardization and benchmark for lecturers in the online class teaching and learning process during the COVID-19 pandemic in the English Education Department of Islamic religious universities in Indonesia. This problem was identified from the results of pre-observation research which indicated that in Indonesian Islamic religious university institutions, especially in the English Language Education study program, there was not yet clear standardization for conducting full online learning. The product of this research study is in the form of a teaching model developed using the ASSURE method that consists of analyzing the participants’ needs, stating the objectives, selecting appropriate strategies, utilizing a technological approach, requiring learners' participation, and evaluating the final product of this study. In developing this research product, the researchers also conducted a validation process with experts in the field of English teaching strategies. The validation is related to the teaching model, model design, and contextualization. The product of this research has been revised and improved based on the advice from the experts. Furthermore, at the stage of requiring students’ participation, the product also underwent trials involving 10 lecturers and 100 students from five different English Education Departments. The results obtained from the trial process were also used by the researchers for perfecting the model so that the teaching model based on blended learning would be an appropriate educational tool to be used in teaching and learning during online learning in the English Education Departments of Islamic religious universities in the future.

AbstractIndonesia consists of tens of thousands of islands and is known as a maritime country that has a very wide sea territory and enormous marine wealth. However, the living conditions of fishermen are generally relatively poor. In such conditions, social networks are very helpful as a strategy for fishermen to survive. This study aims to look at social networks in fishing communities in Cikoang Village, Takalar Regency. The method used is the mix method, namely a combination of methods by combining qualitative and quantitative analysis. This study found that the social network of fishing communities is divided into internal and external social networks. The internal social network of fellow fishermen, close family and neighbors is the social capital that is often used by the fishing community of Cikoang village in a survival strategy. Some fishermen use external social networks in survival strategies such as assistance from distant relatives who are migrating. Fishermen's external social network is not as strong as fishermen's internal social network. Fishermen who have families who are also neighbors are the most strategic social network for survival in the Cikoang Fishermen's Community, Takalar.

Winter rye, which has many valuable properties, is a very important crop in the grain area. The analysis of long-term data on the size of sown areas of winter rye in Russia shows their rapid decline. In this regard, the example of the “Rye” program, implemented by the Finnish government to promote and increase the consumption of rye flour products, as well as the experience of establishing an information center engaged in educational activities among the population is presented. The state of the State Register of Breeding Achievements Approved for Use in winter rye was considered: it was revealed that domestic breeding varieties accounted for 87.1%, foreign - 12.9%. At the same time, 18 varieties exclusively of domestic breeding were recommended for cultivation in Western Siberia, including four varieties of tetraploid rye. Over the past decade, five varieties of winter rye have been registered in the region. The ratio of the size of sown areas under the crop in the Russian Federation as a whole, the Altai Territory and the Novosibirsk Region is presented. The data for the Novosibirsk region for 2019-2021 on the yield of major winter crops, the volume of sowing of winter rye varieties and the hybrids included in the State Register were analyzed. The situation in the production of winter rye and its products, as well as the prospects for the use of this crop in crop rotations in Western Siberia were studied. Indicators of maximum yield of winter rye varieties and hybrids are given, their advantages and disadvantages are listed. The importance of creating a collection of varieties and hybrids in the region and the need to increase the production of winter rye and its products are justified.
