AbstractKanzelhöhe Observatory for Solar and Environmental Research (KSO) of the University of Graz (Austria) is in continuous operation since its foundation in 1943. Since the beginning, its main task was the regular observation of the Sun in full disc. In this long time span covering almost seven solar cycles, a substantial amount of data was collected, which is made available online. In this article we describe the separate processing steps from data acquisition to high level products for different observing wavelengths. First of all we present in detail the quality classification, which is important for further processing of the raw images. We show how we construct centre-to-limb variation (CLV) profiles and how we remove large scale intensity variations produced by the telescope optics in order to get images with uniform intensity and contrast. Another important point is an overview of the different data products from raw images to high contrast images with heliographic grids overlaid. As the data products are accessible via different sources, we also present how to get information about the availability and how to obtain these data. Finally, in an appendix, we describe in detail the information in the FITS headers, the file naming and the data hierarchy.

Public and academic interest in environmental pollution caused by toxic substances and other sources, like noise, is constantly raising. To protect public health and ecosystems it is necessary to maintain the concentrations of pollutants below a safety threshold. In this context the development of models able to assess environmental pollution impact has been identified as a priority for future research. Scientific community has therefore produced many predictive models in the field. The vast majority of them needs to be run by specialists with a deep technical knowledge of the modeled phenomena in order to process the data and understand the results and it is not feasible to use this models for simple prescreening activities. Planners, evaluators and technical operators need reliable, usable and simple tools in order to carry out screening analysis of impact assessment. <br><br> The ENVIFATE software is currently under development by the Department of Civil, environmental and mechanical engineering of the University of Trento, Italy, in the frame of a project funded by the Italian Veneto Region with the aim to make available to nonspecialists screening analysis to assess the risks of a set of possible environmental pollution sources in protected areas. <br><br> The development of ENVIFATE follows these basic requirements: i) Open-Source ii) multiplatform iii) user friendly iv) GIS oriented. In order to respect these principles we have chosen to develop a plugin of QGIS, using python as a development language and creating a module for each environmental compartment analyzed: rivers, lakes, atmospheric dispersion, dispersion in groundwater and noise. <br><br> The plugin architecture is composed of a series of core functions characterized by command line interfaces that can be called from third-party applications (such as Grass GIS), connectable in custom data flows and with a high level of modularity and scalability. The base of the different models are highly tested and reliable algorithms adopted by the Italian Institute for Protection and Environmental Research (Istituto Superiore per la Protezione e la Ricerca Ambientale – ISPRA). Due to their simplicity, and for safety reasons, the structure of these models is constrained to provide conservative results, so to overestimate actual risk. This approach allows to provide statistically validated instruments to be used in different environmental contexts. All modules of the plugin provide numerical and cartographical results: in particular the command-line interface provides "static" results, or linked to a particular spatial and temporal state, while the Qgis plugins iterate the single analysis along space and time in order to provide georeferenced maps and time distributed results.

The Interdepartmental Research Centre for the Development of Crystallography (CrisDi) aims to be an institution of reference for researchers at the University of Turin interested on the field of diffraction (X-rays, neutrons and electrons), to promote the knowledge and dissemination of crystallography, and to facilitate the access to available laboratory instrumentation (diffractometers and TEM) and to large scale facilities (synchrotron and neutron sources). CrisDi hosts scientists with interest in the fields of solid state chemistry and physics, organic, inorganic, organometallic and theoretical chemistry, mineralogy, biology, pharmaceutical and agricultural sciences. The Centre encourages the design and the development of new methodologies and applications, and supports the enhancement of the available instruments. The submission of proposals at large scale instruments is encouraged specially for young researchers and PhD students. The cultural and scientific interchange among crystallographers coming from different disciplines is strongly encouraged by CrisDi. A main task of the CrisDi is the annual organization of a post-grade level School with a series of courses dedicated to: (i) basic level crystallography (symmetry, theory of diffraction, crystal-chemistry), diffraction techniques (single crystal and powder X-ray diffraction, neutron and electron scattering); (ii) advanced level (high temperature and high pressure structural studies, macromolecular crystallography, time resolved crystallography and kinetic studies); (iii) spectroscopic approaches (XAFS, XANES, XES and NMR) in crystallography. The school, which is held every year in May for about 20 ECTS equivalent, has no tuition fees and is also open to non-academia people.

Abstract Background The microbial transglutaminase (mTGase) from Streptomyces mobaraense has been widely used in the food industry. Recombinant production of mTGase is tricky because the mTGase is synthesized as an inactive zymogen, which needs to be activated by proteolytic processing. Self-cleaving inteins have been applied to activate the zymogen in a simple and highly specific manner as compared with proteolytic processing. However, self-cleaving inteins suffer from the inherent problem of premature cleavage. Moreover, self-cleaving inteins normally require an additional step of long time incubation to induce the cleavage. These two inherent problems limit self-cleaving inteins for their potential application in the production of mTGase.Results In this study, the premature cleavage of intein Ssp DnaB was observed in Corynebacterium glutamicum when the Ssp DnaB was used to activate mTGase precursor protein. Rather than suppressing it, the premature cleavage was applied to produce active mTGase in C. glutamicum. The SDS-PAGE analysis and the mTGase activity assay indicated that the premature cleavage of intein Ssp DnaB was successfully applied to activate the mTGase intracellularly in C. glutamicum. The subsequent N-terminal amino acid sequencing and site-directed mutagenesis studies demonstrated that the premature cleavage activated the mTGase intracellularly in a highly specific manner. Finally, in a jar fermentor, the intracellular mTGase activity was up to 49 U/mL, which was the highest intracellular mTGase activity ever reported.Conclusions An efficient and simple approach with great potential for large-scale industrial production of active mTGase was presented in this study. This approach employed premature cleavage of intein Ssp DnaB to activate mTGase in C. glutamicum, resulting in high-level intracellular production of active mTGase. Moreover, this approach did not require any further processing steps such as protease treatment or long time incubation, greatly simplifying the production of active mTGase.

In the article the analysis of construction of training is given in the annual loop of preparation of decathlon competitors, that allows to manage a sport from and provides continuous development of trained. The problem of preparing athletes to competitions is one of the most important in sports training. It is of great practical importance. The increase of the level of sports results is a consequence of a significant increase in the amount of training loads. Further growth of sports results is possible provided the quality of the training process is improved. Analysis of the performances of Ukrainian and foreign athletes at major competitions showed that the vast majority of athletes do not achieve their best results. The competitive period is characterized by the fact that the athlete must maintain for a long time a high level of special physical and technical training, which was acquired in the preparatory period. This can be achieved by using competitive and similar special training exercises. Participation in competitions makes high demands on the athlete's body, so in the competitive period, the athlete in their training sessions should include exercises of general and special nature. The stage of direct pre-competition training (SDPT) is an important component of the athlete's training process in the competitive period. Success in competitions largely depends on the effectiveness of the training process at this stage. It is shown that in the work on the organization and management of training of high-class athletes at the competitive stage, the success of the athlete's performance is largely due to correct scientifically sound predictions that can influence the organizational processes of athletics. The quality and accuracy of these decisions, the responsibility for their adoption increase even more at the stage of direct pre-competition preparation for the main start. Having one goal -performing at the main start, the most highly qualified athletes prepare for this start without speeding up their training, trying to solve the main task.

Large-scale studies of medieval non-fortified points of Southern Rus conducted mainly during the last quarter of XX century within the framework of the targeted program developed by O. P. Motsya, demonstrated quite convincingly the high level of development of Old Russian settlement structures and fully parity relations in the mentioned period between the cities and their outskirts. Somewhat later, when the respective excavations were being deployed, similar conclusions were drawn by experts studying the settlements of Northern Rus. One of the components of this parity is the things in the cultural layers of the settlements which had been previously considered as the elements of urban culture, and some even as representing the feudal lifestyles. Glass bracelets were also attributed to the components of the wealthy town costume: despite the considerable excavations there were found in rural cemeteries and, because of lack of wide scale excavations on settlement structures, were not found on the latter. The data obtained from the mentioned researches of the end of XX — beginning of XXI centuries led to a decisive rejection of this approach and thinking of the «urban» nature of these garnishes in our time publications, if at all mentioned, either due to inertia or as a tribute to the historiographic tradition. Substantially, that before the XII century there were pieces of work of Byzantine craftsmen in Rus affordable mainly to the representatives of the wealthy society group. With the proliferation of mass handi-works of glass-makers in Kiev and other towns of Rus this category of garnishes found its consumer and in locations rather remote from where they were made. At the same time, at some points, the number of the said findings per area unit exceeds even the figures from capitals and it is not always possible to find an explanation for this phenomenon. Khodosivka-Roslavske settlement in the southern suburbs of the capital is one of the archeological sites where the number of fragments of these garnishes is much higher than other items. The settlement was opened by the Northern Expedition of the Institute of Archeology of the National Academy of Sciences of Ukraine in 2007 and is studied annually within the framework of the relevant scientific planning topics. From the first season of excavations, the location has attracted the attention with a rather high level of material culture of its population (precious garnishes, expensive tableware, weapons, items of military equipment, etc.). For five years of work on the site 1041 m2 area was opened, which collected 566 fragments of glass bracelets, although the number of other traditional glass garnishes, i.e. beads, reaches only 8. It is noticeable that the named categories of things by characteristics correspond to the pieces of work traced at other points in Kyivan Rus. At the same time, the features of the bracelets from the settlement are quite substantially different from those of the Kyiv pieces of works, although certain aspects of the high level of development of this point were explained by the inclusion in the structure of the capital metropolis. As a result, neither the chronology of the point, the prosperity of which attributes to the peak of the bracelets making by Old Rus and, first of all, Kyiv craftsmen (though for quite a long time continues after the end of glass making in Rus as a result of the Batyi invasion), nor the neighborhood to the capital, nor significant amount of glazed tableware (the manufacturing technology of which is close to the processes associated with glass making, but the evidence of local development of this industry in the settlement is lacking) does provide an exhaustive explanation of the causes of the said phenomenon. Accordingly, at this stage of research, the traced feature of the point remains one of its specific features, but it testifies for the need of further research of both the Khodosian settlement and the medieval settlements in general, since the excavations of the said category of sites have potential of revealing so far unknown pages of the national Medieval studies.

The paper discusses the problem of the sustainable functioning of the educational system in the context of the intensive development of information technologies, which is urgent in Russia and, practically, in other countries throughout the world. It has become especially acute in recent years in connection with the forced transition to a large-scale organization of distance learning. Based on the analysis of the cultural and historical process in Russia, the most important traditions and features of Russian education are identified, which ensured its sustainable development and world recognition of a high level of quality. The radical economic and social changes at the end of the twentieth century, their consequences and impact on education are considered. The authors point to a number of factors that play a significant role in the development of the education system, determining its flexibility and sustainability. Special attention is paid to modern trends in the development and use of information technologies in education in the context of digitalization of the economy, including distance learning, and the open education system. New objective possibilities are compared that should contribute to the formation of an innovative educational environment of the university, intellectualization of the educational process, and problematic aspects that require detailed study. The authors classify these problems. The directions of their solution are outlined.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.

The article is devoted to the consideration of ways to solve one of the actual problems in theory and methodology of training and upbringing — the problem of developing professional skills of future informatics teacher. As a way to adapt students to the profession, the possibility of their involvement in social designing was chosen. Participation in social projects contributes to the approbation and introduction of new forms and methods in teaching informatics. Expanding the experience of future teachers in carrying out large-scale events contributes to the formation of a socially adapted personality competitive in modern society. The potential of a social project in consolidating the knowledge and skills obtained during the theoretical training at the university is indicated. In the article, theoretical reasoning is accompanied by examples of real social projects and activities aimed at the formation of professional competencies of future informatics teachers.

Cruel and inhumane acts that harm human life and health, as well as humiliate the dignity, are prohibited in most countries of the world, and Russia is no exception in this issue. The article presents an analysis of the institution of responsibility for torture in the Russian Federation. The author comes to the conclusion that the current criminal law of Russia superficially and fragmentally regulates liability for torture, in connection with which the author formulated the proposals to define such act as an independent crime. In the frame of modern globalization, the world community pays special attention to the protection of human rights, in connection with which large-scale international standards have been created a long time ago. The Universal Declaration of Human Rights and other international acts enshrine prohibitions of cruel and inhumane acts that harm human life and health, as well as degrade the dignity.Considering the historical experience of the past, these standards focus on the prohibition of any kind of torture, regardless of the purpose of their implementation.

This paper traces the partnership between the University of Toronto and the non-profit Local Food Plus (LFP) to bring local sustainable food to its St. George campus. At its launch, the partnership represented the largest purchase of local sustainable food at a Canadian university, as well as LFP’s first foray into supporting institutional procurement of local sustainable food. LFP was founded in 2005 with a vision to foster sustainable local food economies. To this end, LFP developed a certification system and a marketing program that matched certified farmers and processors to buyers. LFP emphasized large-scale purchases by public institutions. Using information from in-depth semi-structured key informant interviews, this paper argues that the LFP project was a disruptive innovation that posed a challenge to many dimensions of the established food system. The LFP case study reveals structural obstacles to operationalizing a local and sustainable food system. These include a lack of mid-sized infrastructure serving local farmers, the domination of a rebate system of purchasing controlled by an oligopolistic foodservice sector, and embedded government support of export agriculture. This case study is an example of praxis, as the author was the founder of LFP, as well as an academic researcher and analyst.
