Published: April 2021

The immigration crisis in Europe and its consequences are our collective responsibility as Europeans, and it is important to show solidarity by providing immigrants with much needed support, based on generally accepted human rights and moral responsibility issues. Along with the challenges posed by the migrant crisis the issue came up of better integration of immigrants into society, providing the necessary information regarding the assistance offered, social guarantees, protection, and knowledge of local culture, traditions, history and educational opportunities.
Summarizing the empirical research data, it can be concluded that the portrait of a Latvian immigrant is as follows: average age - 29.9 y/o, coming to Latvia to look for a job 45% or 24% to study, 44% married or in non-registered relationship, 39% have little information about Latvia or in 13% of cases there has been no information, in 93% of cases immigrants want to get some information about Latvia – the Internet and friends (other immigrants or residents) are mentioned as the most popular sources of information. In turn, educators working with immigrants confirm that integration and educational issues are particularly important in the first year since arriving to Latvia, focusing on learning the national language, providing a place to live, and providing direct support in a specific life situation. At this stage, it is especially important to provide professionally oriented and accessible lifelong learning, which can contribute to the better integration of migrants into the local community and the labour market.
Latvijas izglītības reformas vērtējums pedagogu vidē pamatskolas 1.–3. klasē: gadījuma analīzes piemērs
Authors: Pelnēna Ivita , Medveckis Arturs
Published: April 2021

The 21st century is an essential time for changes in the society. Development of technologies, globalisation and the fading of national boundaries all contribute to a change of the educational paradigm.
The changes also affect the Latvian education system as the implementation of the project “Competency approach in learning content” is in progress. The implementation of the new learning content has began on September 1 of the academic year 2020/2021. To determine the Primary school teachers’ (Grades 1-3) readiness for putting the changes into practice, a survey was conducted. The survey data analysis shows that the teachers admit that changes are necessary; meanwhile they believe that the implementation of changes is chaotic. Likewise, teachers are not insecure about the new learning content that is added to the curriculum. Teachers discuss problems such as information fragmentation, lack of technologies and learning materials, insufficient amount of lessons intended for a particular content as well as its influence on qualitative preparation of lessons.
Pedagoģiskās mijiedarbības transformācija mācību procesā pandēmijas laikā
Authors: Niedre-Lathere Kristīne , Samuseviča Alīda
Published: April 2021

The authors of the article address a current and socially significant problem of teachers' work, raising the issue of pedagogical interaction transformations in the planning and implementation of the pupils' learning process during the Covid19 Pandemic. In the article, the factors influencing the quality of the distance education process in the digitalization of the learning process and pedagogical communication are identified, based on the analysis of theoretical understanding of educational challenges and analysis and characterization of the survey data implemented in practice. The article mentions identified contradictions that lead to the changes in teachers' pedagogical thinking and activities, in order to improve the quality of pedagogical interaction for implementation of a successful and resultative distance learning, focusing on pupils and teachers’ needs and defining a purposeful, timely inter-institutional cooperation and its practical implementation, developing resources and potential of the educational field in order to enhance every pupil’s individual growth.
The empirical research data have been obtained, applying the EDURIO survey platform, which guarantees credibility of the results and provides a profound data analysis in the professionally involved research target audiences. The target audience of the survey is teachers, pupils and parents. The experience of the teaching practice during the distance learning confirms that a learning process in which pupils need parents’ support as little as possible has to be developed purposefully, or the school has to provide an extra help and support for the pupils whose parents’ support is restricted. Lots of activities performed by parents during the distance learning are also desirable at home as an addition to onsite learning – search for information resources or share one’s knowledge (performed by 63 % of parents), help children to plan their time (30 % of parents), encourage children (33 % of parents), talk over with the child the success at school (30 % of parents). The research data support the opinion that in the context of education, pedagogical cooperation needs to be strengthened and supervisions raised, involving all management forces and agents of change.
Based on the research findings, the recommendations are offered to the specialists of Liepaja City Municipal Department of Education and City’s administration for high-quality development of school staff implementing the pedagogical processes of digital transformation on a daily basis.

Structure Topology and Graphical Representation of Decorated and Undecorated Chains of Edge-Sharing Octahedra
Authors: Lussier Aaron J. , Hawthorne Frank C.
Published: April 2021

Infinite chains of edge-sharing octahedra occur as fundamental building blocks (FBBs) in the structures of several hundred mineral species. Such chains consist of a backbone of octahedra to which decorating polyhedra may be attached. The general, stoichiometric formula of such chains may be written as c[MATxФz] where M is any octahedrally coordinated cation, T is any cation coordinated by a decoration polyhedron (regardless of coordination geometry), Ф is any possible ligand [O2–, (OH)–, (H2O), Cl–, or F–], and c indicates the configuration of backbone octahedra. In the minerals in which they occur, these types of chains will commonly (though not exclusively) form part of the structural unit (i.e., the strongly bonded part) of a mineral. Hence, investigating the topology, configuration, and arrangement of such chains may yield fundamental insights into the stability of minerals in which they occur. A discussion of the topological variability of chains is presented here, along with the formulae necessary for their characterization. It is shown that many aspects of chain topology can be efficiently communicated by a pair of values with the form ([x], [Bopqrst]), where [x] summarizes the symmetry operations necessary to characterize the configuration of backbone octahedra, B indicates the length of the topological repeat, and o through t indicate the number of individual decorations (related to B). A methodology for developing finite graphical representations for infinite chains is presented in detail, showing that for any given chain, a single, irreducible finite graph exists that contains all topological information. Such a graph, however, can correspond to multiple chain topologies, highlighting the importance of geometrical isomerism. The utility of the graphical approach in facilitating the development of a hierarchy of chains and chain-bearing structures is also discussed.
Catalogue of plant fossils described in works by Kaspar M. Sternberg. Second revised edition
Authors: Kvaček Jiří , Dašková Jiřina , Libertín Milan
Published: April 2021

This Catalogue is the second revised and expanded edition of the first edition, published in 1997 by J. Kvaček and Straková. The material presented in the original edition was completely nomenclaturally revised and newly photodocumented. This second edition provides as much updated information as it was possible to acquire. The Catalogue includes and reviews new nomenclatural and taxonomic assignments of Sternberg’s type material and taxa published after 1997. It is clear that much of the impulse to conduct this new research came from the first edition of the Catalogue, as the community realized the type material is available for study.
In summary, the second edition of the Catalogue comprises specimens that are types of 82 genera, 3 subgenera, 535 species and 14 varieties described by Kaspar Maria Count Sternberg and his collaborators: K. B. Presl and A. C. J. Corda. The type material of 32 genera, 233 species and 5 varieties is housed in the National Museum, Prague. The types of 79 species and 4 varieties have been located in other European museums. The rest of the type specimens are currently missing – destroyed, lost, or of unknown repository. For available specimens, more detailed taxonomic, stratigraphic and geographical information is provided. All cases are noted where names in Sternberg’s works have priority over names currently used, although the current names may be more widely known. Only two nomenclatural acts are published in the present work; they are designations of a lectotypes for Aspleniopteris difformis Sternb. and Cycadites salicifolius C.Presl in Sternberg.

Energiespeicher sind Schlüsselelemente für eine erfolgreiche Energiewende. Sie ermöglichen ein defossilisiertes, erneuerbares und versorgungssicheres Energiesystem. Eine Vielzahl an Energiespeichertechnologien steht für den Einsatz im Markt zur Verfügung: von den klassischen Pumpspeichern, den Wärmespeichern, den Batteriespeichern mit derzeit starkem Marktwachstum bis hin zu Power-to-X-Lösungen. Allerdings lässt der deutsche Rechtsrahmen bisher wenig Raum zur vollen Potenzialentfaltung der Speicher zu. Um Energiespeicher als Schlüsselelement für die Energiewende zukünftig besser nutzen zu können, sind weiterhin neben regulatorischen Anpassungen auch technische Weiterentwicklungen und damit verbundene Kostensenkungen erforderlich.

In dem Anfang des Jahres zwischen CDU/CSU und SPD geschlossenen Koalitionsvertrag wird die Notwendigkeit eines Klimaschutzgesetzes hervorgehoben. Mit dem Gesetz sollen die Ziele des Klimaschutzplans und die dafür notwendigen Maßnahmen rechtsverbindlich festgelegt werden. Darüber hinaus hat sich die große Koalition zum Ziel gesetzt, den Anteil erneuerbarer Energien an der Stromerzeugung bis zum Jahr 2030 auf 65 % zu steigern. Trotz aller Bemühungen zeichnet sich ab, dass das Klimagasreduktionsziel von – 40 % bis zum Jahr 2020 deutlich verfehlt wird. Vor diesem Hintergrund setzte die Bundesregierung eine Strukturkommission („Kohlekommission“) ein, die Vorschläge und flankierende strukturelle Maßnahmen für einen Ausstieg aus der Kohleverstromung erarbeitet hat. Wie bereits in den Vorjahren [1] bleibt der notwendige Stromnetzausbau deutlich hinter den ursprünglichen Planungen. Auf Initiative des Bundesministeriums für Wirtschaft und Energie (BMWi) wurde eine Novellierung des Netzausbeschleunigungsgesetzes vorbereitet, um den Zeitverzug aufzuholen. Zur Stabilisierung des Netzes hat die Bundesnetzagentur den Übertragungsnetzbetreibern die Erlaubnis erteilt, zusätzliche Netzstabilisierungsanlagen im Süden Deutschlands aufzubauen. Hierfür zeichnen sich die ersten Kraftwerksprojekte ab.

Insgesamt wurde in 2018 so viel Energie aus erneuerbaren Energien genutzt wie niemals zuvor. Dies gilt neben der (festen) Biomasse zur Bereitstellung insbesondere thermischer Energie primär für die Erzeugung elektrischer Energie. Stromerzeugungsanlagen – unter anderem auf der Basis von Wasserkraft, Biomasse, Windenergie und Solarstrahlung – waren 2018 für etwa ein Viertel der globalen Stromerzeugung verantwortlich. Demgegenüber zeigte die Wärme- und Kraftstoffbereitstellung aus erneuerbaren Energien auch 2018 nach wie vor nur einen unterdurchschnittlichen beziehungsweise stagnierenden Anstieg. Diese Entwicklung dürfte auch in den kommenden Jahren weitergehen.

El alero Los Viscos es un sitio arqueológico de importantes dimensiones y complejidad que comenzó a ser estudiado en los ´90.  En el año 2017, siguiendo las nuevas perspectivas de investigaciones del equipo y la disponibilidad de herramientas de medición más precisas, se emprendió la tarea de realizar un nuevo levantamiento arqueológico y un plano que constituya una base descriptiva e interpretativa del sitio. Este artículo busca ser una historiografía cartográfica de los últimos 25 años de trabajo en este sitio en particular y sus implicaciones para las investigaciones locales, pero a su vez también aportar elementos para pensar en los procesos descriptivos e interpretativos involucrados en el mapeo arqueológico en general. Entendemos que un levantamiento arqueológico debe no sólo considerar la parte técnica del registro, bases cartográficas previas y evaluar de las herramientas de medición, registro y representación, sino que requiere nuestra atención y vigilancia epistemológica en la toma de decisiones y negociaciones, ya que la historia de cada sitio y las narrativas que desde el mismo se construyen están basadas también en su representación cartográfica, sea esta explícita o no.

Published: April 2021

One of the parameters that ensure the electromagnetic compatibility of fighting vehicles of modern anti-aircraft missile and gun systems, when they are operating as a part of the battery, is the standard frequency of the multifunctional radio station and the target locator of each fighting vehicle. A mathematical model of the optimal distribution of standard frequencies has been built with account for fighting vehicles location, the available frequency setting, compatibility restrictions and limits on distribution uniformity in a given frequency range with a view to enemy’s directional jamming. The considered method has been tested on the example of different arrangements of fighting vehicles, depending on the standard frequency setting and the number of fighting vehicles of the battery.

Authors: Smirnov M. A.
Published: April 2021

The study introduces a method that evaluates the effectiveness of information resources of an air defense missile system when detecting a hypersonic cruise missile. The method takes into account the dynamic target scattering crossover. The efficiency is evaluated by conducting statistical tests on a simulation model and constructing a vertical section of the detection zone. In this case, the effective target scattering crossover of a hypersonic cruise missile is calculated depending on the parameters of its movement around the center of mass relative to the ground - based detection radar and its line of sight

Authors: Peshkov R. A. , Ismagilov D. R.
Published: April 2021

The paper introduces a mathematical model for calculating the gas-dynamic parameters in the launch container. The model takes into account chemical interactions between the main components of the combustion products, i.e. carbon monoxide and hydrogen, and oxygen. The resulting energy can be used to increase the initiating pulse of the rocket. Within the research, we described the basic requirements for the grid model, and analyzed the accuracy of the results obtained. Furthermore, we compared calculation data of pressure in the launch container with the results of the known method. Findings of research show that the use of two-dimensional and three-dimensional models makes it possible to obtain not only medium-volume gas-dynamic parameters, such as pressure, temperature, density, but also the distribution of these parameters over the computational domain. The developed method of numerical simulation will allow us to estimate the effect of changes in the configuration of the sub-rocket volume and other parameters on the dynamics of the rocket movement without conducting an expensive experiment
