Mehrlagige mikrofluidische Systeme aus Polymeren zur zweidimensionalen Kapillarelektrophorese

Im Rahmen dieser Arbeit wurde ein mehrlagiges mikrofluidisches Lab-on-a-Chip-System auf Polymerbasis für den Einsatz in der Ionenanalytik, Lebensmittelanalytik und Bioanalytik entwickelt. Hierfür wurden Folienchips mit einer integrierten Membran auf PC-COC-Basis und Folienchips auf PEEK-Basis hergestellt, welche die Durchführung einer zweidimensionalen Kapillarelektrophorese (2D-CE) mit kapazitiv gekoppelter kontaktloser Leitfähigkeitsdetektion auf einem Chip ermöglichen

The Role of University in Heritage Research and Practice: Siberian Context

The risk of losing identity and historical values seems indispensable as attributes of the explosive growth of modern cities. However, along with the disappearance of each piece of heritage, citizens tend to lose memories and "identical" feelings, which make the place special and unique. The role of universities and architects in the heritage process of the modern city can be more significant: there are many successful examples around the world, which clearly demonstrate that the group of researchers from the Siberian Federal University made an attempt to compensate both for the lack of connection between the university and the city, and the lack of comprehensive approaches to the heritage process in Krasnoyarsk, Siberia. For the experimental design research, the part of the Military camp, the degrading place with a bright history in Krasnoyarsk, was selected. Thorough research and examination are required to extract the values of the place. For the experiment, students conducted a deep analysis of historical facts, values, narratives, habits, and beliefs before developing their project proposals. The paper questions the role of the university and architects in the heritage process of modern Siberian city, experimenting with the particular precedent in Krasnoyarsk and suggests the methods of participation in sustaining identity and providing continuity in historical environments

Reading urban form as a studio teaching method: case study in Siberia

Quite often heritage monument is perceived as a separate domain in Russian conservation theory and practice. Teaching practice demonstrates the situation clearly: quite commonly studio regeneration projects are conducted in isolation from the context, or lacking the methodology for preliminary analysis. However, many international concepts attempt to avoid isolation of buildings as physical objects from a cultural environment with its multi-layered history of significances (Waterton & Watson, 2015). The paper presents a case study of the application of urban morphology as a research tool and a teaching method (Caniggia & Maffei, 2001), to the Siberian context. Research group of Siberian Federal University (SFU) organized the experiment, in which students worked on the two stages of a regeneration project for the old Military camp in Krasnoyarsk. Between the two stages, the workshop was organized for students of Sapienza University and SFU to conduct a methodological study. Then the research group continued the second stage of the experiment in which examined the applicability of morphological analysis in Siberia. The qualitative difference of regeneration proposals before and after the application of morphological analysis, as well as the level of subsequent students’ proficiency, proved the potential applicability of the method in Siberian academy and practice, and effectiveness of the workshop as the tool for its introduction

SEMANTIC FEATURES OF THE PHRASEOLOGICAL UNITS WITH THE COMPONENT LIGHT THE WITHIN ARTISTIC DISCOURSE

Purpose: To conduct lexical and semantic analysis on the concept light in the artistic discourse of postmodern fiction. Methodology: In this research, comparative method, search for synonyms, continuous sampling and seminal analysis are used. Main Findings: As a result, it becomes obvious that the boundaries of the artistic concepts are extremely blurred and much wider than the boundaries of the corresponding non-artistic concepts. In conclusion, the concept light is frequently used in English artistic discourses, i.e. significant in the culture, and a special status in the semantic space of the concept light has the meaning of knowledge and information. Applications: The study results can be used by students and universities. Novelty/Originality: In this research, a model of the semantic features of the phraseological units with the component light is presented in a comprehensive and complete manner

Erot spatiaalisissa ja ajallisissa reaktionormeissa kevään ja syksyn fenologisille tapahtumille

For species to stay temporally tuned to their environment, they use cues such as the accumulation of degree-days. The relationships between the timing of a phenological event in a population and its environmental cue can be described by a population-level reaction norm. Variation in reaction norms along environmental gradients may either intensify the envi- ronmental effects on timing (cogradient variation) or attenu- ate the effects (countergradient variation). To resolve spatial and seasonal variation in species’ response, we use a unique dataset of 91 taxa and 178 phenological events observed across a network of 472 monitoring sites, spread across the nations of the former Soviet Union. We show that compared to local rates of advancement of phenological events with the advancement of temperature-related cues (i.e., variation within site over years), spatial variation in reaction normsPeer reviewe

Chronicles of nature calendar, a long-term and large-scale multitaxon database on phenology

We present an extensive, large-scale, long-term and multitaxon database on phenological and climatic variation, involving 506,186 observation dates acquired in 471 localities in Russian Federation, Ukraine, Uzbekistan, Belarus and Kyrgyzstan. The data cover the period 1890-2018, with 96% of the data being from 1960 onwards. The database is rich in plants, birds and climatic events, but also includes insects, amphibians, reptiles and fungi. The database includes multiple events per species, such as the onset days of leaf unfolding and leaf fall for plants, and the days for first spring and last autumn occurrences for birds. The data were acquired using standardized methods by permanent staff of national parks and nature reserves (87% of the data) and members of a phenological observation network (13% of the data). The database is valuable for exploring how species respond in their phenology to climate change. Large-scale analyses of spatial variation in phenological response can help to better predict the consequences of species and community responses to climate change.Peer reviewe

Phenological shifts of abiotic events, producers and consumers across a continent

Ongoing climate change can shift organism phenology in ways that vary depending on species, habitats and climate factors studied. To probe for large-scale patterns in associated phenological change, we use 70,709 observations from six decades of systematic monitoring across the former Union of Soviet Socialist Republics. Among 110 phenological events related to plants, birds, insects, amphibians and fungi, we find a mosaic of change, defying simple predictions of earlier springs, later autumns and stronger changes at higher latitudes and elevations. Site mean temperature emerged as a strong predictor of local phenology, but the magnitude and direction of change varied with trophic level and the relative timing of an event. Beyond temperature-associated variation, we uncover high variation among both sites and years, with some sites being characterized by disproportionately long seasons and others by short ones. Our findings emphasize concerns regarding ecosystem integrity and highlight the difficulty of predicting climate change outcomes. The authors use systematic monitoring across the former USSR to investigate phenological changes across taxa. The long-term mean temperature of a site emerged as a strong predictor of phenological change, with further imprints of trophic level, event timing, site, year and biotic interactions.Peer reviewe

Establishment of Creative Museum for Children in Riga

Informācijas vide mūsdienu sabiedrības un indivīda dzīvē kļūst par jaunu un nozīmīgu sociālo fenomenu, līdz ar to tieša savstarpējā cilvēku komunikācija kļūst otršķirīga, kas īpaši ietekmē bērnu attīstību. Maģistra darba “Radoša bērnu muzeja izveide Rīgas teritorijā” mērķis ir paplašināt brīvā laika pavadīšanas iespējas Rīgā dzīvojošajām ģimenēm ar bērniem. Problēmas apzināšanai un attīstības iespēju noteikšanai veikts pētījums par ģimeņu brīvā laika pavadīšanas ieradumiem. Pētījuma rezultāti rāda, ka Rīgā dzīvojošās ģimenes nav apmierinātas ar brīvā laika pavadīšanas iespēju piedāvājumu Rīgā, jo izklaides un atpūtas objekti nepiedāvā iespēju bērniem apgūt pamācošu un daudzveidīgu informāciju. Autore problēmas risinājumu piedāvā projekta veidā, kura ietvaros Rīgas teritorijā tiks uzbūvēts Bērnu radošais muzejs.Information environment of modern society and an individual's life become a new and important social phenomenon, as face-to-face human communication becomes secondary, particularly affecting children's development. The purpose of Master's Thesis Establishment of Creative Museum for Children in (the Territory of) Riga is to expand leisure facilities for families with children – residents of Riga. The research has been made to challenge and identify development opportunities for family leisure habits. The research results show that families living in Riga are not satisfied with the offer of leisure activities; entertainment and recreational facilities do not offer children the opportunity to learn instructive and diverse information. The author offers a solution to the problem in the form of a project, under which a creative museum for children should be established in the territory of Riga
