The EnMAP imaging spectroscopy mission towards operations

EnMAP (Environmental Mapping and Analysis Program) is a high-resolution imaging spectroscopy remote sensing mission that was successfully launched on April 1st, 2022. Equipped with a prism-based dual-spectrometer, EnMAP performs observations in the spectral range between 418.2nm and 2445.5nm with 224 bands and a high radiometric and spectral accuracy and stability. EnMAP products, with a ground instantaneous field-of-view of 30m×30m at a swath width of 30km, allow for the qualitative and quantitative analysis of surface variables from frequently and consistently acquired observations on a global scale. This article presents the EnMAP mission and details the activities and results of the Launch and Early Orbit and Commissioning Phases until November 1st, 2022. The mission capabilities and expected performances for the operational Routine Phase are provided for existing and future EnMAP users

Towards Experimental Handbooks in Catalysis

The “Seven Pillars” of oxidation catalysis proposed by Robert K. Grasselli represent an early example of phenomenological descriptors in the field of heterogeneous catalysis. Major advances in the theoretical description of catalytic reactions have been achieved in recent years and new catalysts are predicted today by using computational methods. To tackle the immense complexity of high-performance systems in reactions where selectivity is a major issue, analysis of scientific data by artificial intelligence and data science provides new opportunities for achieving improved understanding. Modern data analytics require data of highest quality and sufficient diversity. Existing data, however, frequently do not comply with these constraints. Therefore, new concepts of data generation and management are needed. Herein we present a basic approach in defining best practice procedures of measuring consistent data sets in heterogeneous catalysis using “handbooks”. Selective oxidation of short-chain alkanes over mixed metal oxide catalysts was selected as an example.DFG, 390540038, EXC 2008: Unifying Systems in Catalysis "UniSysCat

Lehrgut

Diese Publikation erscheint begleitend zur Ausstellung »Lehrgut. Kunstgeschichte in Schulbüchern und Unterrichtsmedien um 1900« in der Universitätsbibliothek der Universität Siegen, 4. – 31. Juli 2018.Seit Mitte des 19. Jahrhunderts wurde die Einführung eines kunstgeschichtlichen Schulunterrichts in Deutschland kontrovers diskutiert. Durch die neuen Möglichkeiten der Fotografie waren ortsgebundene Artefakte im Medium des gedruckten Bildes universell verfügbar geworden. Vielen erschien es folgerichtig, das elitäre Bildungsgut der bildenden Kunst jetzt auf dem Weg der schulischen Vermittlung allen Schichten zugänglich zu machen. Verlage stellten sich mit entsprechenden Lehrbüchern, Mappenwerken und Wandbildern schnell auf den wachsenden Bedarf ein. Befördert wurde das Anliegen durch die wissenschaftliche Pädagogik, die das Lernen durch Anschauung favorisierte und eine Modernisierung schulischer Curricula vorantrieb. Dem Kunstbuch im Schulunterricht widmete sich die Publikation mit einer Vielzahl von Beispielen aus der Zeit von 1880 bis 1930

Towards Modeling and Measuring Information Literacy in Secondary Education

The networked information and media society provides us increasingly with digital information and knowledge. However, the effective and efficient use of information requires a high level of information literacy (IL), i.e. adequate capabilities to deal with information. Despite of its growing importance, IL has been considered only sporadically in information systems research and education. There is a lack of a scientifically proven model to operationalize and measure IL. The paper contributes to fill this gap by providing a synthesis on existing research related to definition, conceptualization and measurement of IL. Applying the proposed framework through a survey with 86 high school students, we find relatively poor skill levels for the objective IL for most of the students, while the self-assessed IL is distinctly higher. In addition, our study shows that individual differences in IL can be explained by the student’s grade, web experience and the comprehension of the curriculum

The 7i Framework - Towards a Measurement Model of Information literacy

The networked information and media society provides us increasingly with digital information and knowledge. However, the effective and efficient use of information requires a high level of information literacy (IL), i.e. adequate capabilities to deal with information. IL is in general described as the ability to recognize problem-driven information needs, to select information sources, to access, evaluate and use information, and to reflect upon both the applied information searching and processing procedure and the information resulting from it. Despite of its growing importance, IL has been considered only sporadically in information systems research and education. There is a lack of a scientifically proven model to operationalize and measure IL. The paper contributes to fill this gap by providing a synthesis on existing research related to definition, conceptualization and measurement of IL. Based on the findings of the literature analysis the 7i model for measuring IL is proposed

New insights into MagPI: a promising tool to determine the adhesive capacity of biofilm on the mesoscale

The adhesiveness and stability of ubiquitously distributed biofilms is a significant issue in many areas such as ecology, biotechnology and medicine. The magnetic particle induction (MagPI) system allows precise determinations of biofilm adhesiveness at high temporal and spatial resolution on the mesoscale. This paper concerns several technical aspects to further improve the performance of this powerful experimental approach and enhance the range of MagPI applications. First, several electromagnets were built to demonstrate the influence of material and geometry with special regard to core remanence and magnetic strength. Secondly, the driving force to lift up the particles was evaluated and it was shown that both the magnetic field strength and the magnetic field gradient are decisive in the physics of the MagPI approach. The intricate combination of these two quantities was demonstrated with separate experiments that add permanent magnets to the MagPI system
