Learning in the Era of Online Videos: How to Improve Teachers’ Competencies of Producing Educational Videos

[EN] Online videos have gained huge popularity among people seeking for entertainment, and increasingly also among learners. People seek for tips in videos, ranging widely from improving language skills to bike reparation, or from solving mathematical equations to indoor decoration. At the same time teachers are facing challenges of producing professional videos that can support learners to learn the variety of topics. Teachers at the higher education institutes are often professionals in presentation skills in classrooms, but can face challenges when presenting in videos. In this paper we present a process for improving skills needed to produce educational videos. The process starts from the assumption of often explicit question by the teacher: “How can I produce professional educational videos?” The process includes identifying main challenges teachers face, and continues with a series of hands-on workshops targeted to develop each of the skills followed by the video production itself. We report also an evaluation of the process with teachers from the Aalto University, discuss the implications and resulting categorization of production models.http://ocs.editorial.upv.es/index.php/HEAD/HEAD18Guseva, Y.; Kauppinen, T.

This article reveals the essence of the process of digitalization of educational activities. The authors considered the features of implementation, positive and negative aspects of digital technologies in education. The authors also describe the world experience of leading universities in the digitalization of the educational process

Black Soldier Fly (Hermetia illucens), a source of antimicrobial peptides

In the modern world, multi-drug antibiotic resistance is an increasingly serious problem which poses a serious threat to both plants, animals and humans. The unreasonable use of antibiotics has led to the spread and increase in the number of infectious diseases that existing antibiotics may not be able to cope with. Thus, there is a need for the development of new classes of antibiotics that do not induce resistance. It is necessary to find agents with new mechanisms of action for the development of such antimicrobial compounds. Antimicrobial peptides are excellent candidates for this role. Penetrating through the membranes, they affect the target protein without high specificity, which in turn reduces the probability of induced resistance to a minimum [13]. Scientists have identified about 57 active peptides belonging to various groups of antimicrobial peptides, including defensins, cecropins, attacins and lysozyme. Defensins form the largest group of antimicrobial peptides in insects. As a rule, a defensin-like peptide contains from 34 to 43 amino acids. Antimicrobial peptides obtained from Hermetia illucens can become a good alternative to antibiotics for the prevention and treatment of infectious diseases, as they differ in their antimicrobial properties and are less likely to induce resistance [8]. The lipid composition as well as the amino acid composition can be changed by different larvae diets. Larvae fat contains oleic, palmitic, lauric, myristic, stearic and palmitolic acids, which are saturated and unsaturated fatty acids, and have an intense effect against bacteria

The Impact of the Global Financial Crisis on Russia's Cooperation with the Countries of EurAsEC

The article considers the impact of the financial and economic crisis on Russia's cooperation with the EurAsEC countries. Because crises are an integral part of any economic system, a deep analysis should be carried out. We consider the integration at the micro level and prospects of Russia's cooperation with the EurAsEC, the prospects for cooperation between Russia and the EurAsEC countries should be assessed in different ways. Speaking about the cooperation it should be noted that the main weakness of the countries dependent on the prices of natural resources, which are the main export of all countries, including Russia. After all, the raw material orientation determines the country's place in the world. And so the main task here is to develop the production of finished products and the development of knowledge-based industries. Keywords: EurAsEC countries, financial crisis, problems of cooperation, economic globalization. JEL Classifications: F63, F65, G01, H1

Elemental speciation of the sediments from cold methane seeps on the Laptev Sea shelf

Relevance. The lack of elemental speciation data in the bottom sediments of the Laptev Sea, as well as the absence of its quantitative changes in occurrence forms in response to methane emissions. Aim. To assess changes in the elemental speciation in areas where methane-containing fluids are discharged. Objects. Nine samples of bottom sediments taken from three horizons of one “cold seep” and two background stations of the outer shelf-continental slope of the Laptev Sea during the AMK-82 expedition aboard R/V “Academician M.V. Keldysh” in autumn 2020. Methods. Sequential extraction BCR (the European Community Bureau of Reference) was performed to determine the elemental speciation in surface sediments; the residual fraction was determined by dissolving in nitric acid. The obtained fraction solutions were analyzed by ICP-MS (NexIon 300D, Perkin Elmer, Waltham, MA, USA), Pyrolysis (Rock-Eval 6 Turbo, Vinci Technologies). Results. The trend towards an increase in element mobility has been identified as a result of a shift in geochemical conditions that is presumably caused by the authigenic carbonate and sulfide formation. Moreover, the increase in the recoverable fraction (associated only with Fe oxides/hydroxides) is highlighted. We assume that the process of unloading methane-containing fluids plays a significant role in enrichment of authigenic carbonates U, Ni, Zn Co, oxides Fe – Sn and V, authigenic sulfides – Co, Mn and W. We also assume the potential formation of chalcopyrite as an authigenic sulfide in methane discharge areas

Large-Scale Recombinant Production of the SARS-CoV-2 Proteome for High-Throughput and Structural Biology Applications

The highly infectious disease COVID-19 caused by the Betacoronavirus SARS-CoV-2 poses a severe threat to humanity and demands the redirection of scientific efforts and criteria to organized research projects. The international COVID19-NMR consortium seeks to provide such new approaches by gathering scientific expertise worldwide. In particular, making available viral proteins and RNAs will pave the way to understanding the SARS-CoV-2 molecular components in detail. The research in COVID19-NMR and the resources provided through the consortium are fully disclosed to accelerate access and exploitation. NMR investigations of the viral molecular components are designated to provide the essential basis for further work, including macromolecular interaction studies and high-throughput drug screening. Here, we present the extensive catalog of a holistic SARS-CoV-2 protein preparation approach based on the consortium’s collective efforts. We provide protocols for the large-scale production of more than 80% of all SARS-CoV-2 proteins or essential parts of them. Several of the proteins were produced in more than one laboratory, demonstrating the high interoperability between NMR groups worldwide. For the majority of proteins, we can produce isotope-labeled samples of HSQC-grade. Together with several NMR chemical shift assignments made publicly available on covid19-nmr.com, we here provide highly valuable resources for the production of SARS-CoV-2 proteins in isotope-labeled form
