Am Ende der GYM2: Ergebnisse zur dritten Befragung: MEGY-Info 03
No full textDas Projekt MEGY - Mit Erfolg durchs Gymnasium schreitet voran. Schülerinnen und Schüler, die im Jahr 2017 mit der gymnasialen Maturitätsausbildung im Kanton Bern begonnen haben, wurden bisher viermal befragt. Die erste Erhebung fand im Herbst 2017 statt, die vierte wurde kürzlich unter besonderen Bedingungen – während der Zeit des Fernunterrichts – abgeschlossen.
In der vorliegenden MEGY-Info 03 präsentieren wir ausgewählte Ergebnisse zur dritten Befragung (Ende GYM2, 2019). Sie beinhaltet Befunde zur Weiterentwicklung fachspezifischer Interessen sowie zu lern- und erfolgsrelevanten Einschätzungen und Strategien der Schülerinnen und Schüler. Am Schluss berichten wir über einzelne allgemeine Einschätzungen aus der aktuellen Befragung, wie die Jugendlichen die Zeit im Fernunterricht erlebt haben.
Wie entwickeln sich die Interessen der Schülerinnen und Schüler in Mathematik, Deutsch und Französisch? Wie nehmen die Schülerinnen und Schüler den Unterricht in diesen Fächern wahr? Mit welchen Noten sind sie zufrieden? Und was bedeutet für sie «Schulerfolg»? Antworten auf diese und weitere Fragen finden sich auf den nächsten Seiten.
An der dritten Befragung haben sich 1356 Schülerinnen und Schüler beteiligt. Davon haben bereits 1024 an den ersten beiden Erhebungen teilgenommen. Ein herzliches Dankeschön geht an alle Schülerinnen und Schüler, die mitgemacht haben, sowie an alle Lehrpersonen, die uns dabei unterstützt haben
An intracellular pH gradient in the anammox bacterium Kuenenia stuttgartiensis as evaluated by (31)P NMR
No full textThe cytoplasm of anaerobic ammonium oxidizing (anammox) bacteria consists of three compartments separated by membranes. It has been suggested that a proton motive force may be generated over the membrane of the innermost compartment, the “anammoxosome”. 31P nuclear magnetic resonance (NMR) spectroscopy was employed to investigate intracellular pH differences in the anammox bacterium Kuenenia stuttgartiensis. With in vivo NMR, spectra were recorded of active, highly concentrated suspensions of K. stuttgartiensis in a wide-bore NMR tube. At different external pH values, two stable and distinct phosphate peaks were apparent in the recorded spectra. These peaks were equivalent with pH values of 7.3 and 6.3 and suggested the presence of a proton motive force over an intracytoplasmic membrane in K.stuttgartiensis. This study provides for the second time—after discovery of acidocalcisome-like compartments in Agrobacterium tumefaciens—evidence for an intracytoplasmic pH gradient in a chemotrophic prokaryotic cell.BiotechnologyApplied Science
Concept and development of an autonomous wearable micro-fluidic platform for real time pH sweat analysis
No full textIn this work the development of an autonomous, robust and wearable micro-fluidic platform capable of performing on-line analysis of pH in sweat is discussed. Through the means of an optical detection system based on a surface mount light emitting diode (SMD LED) and a light photo sensor as a detector, a wearable system was achieved in which real-time monitoring of sweat pH was performed during 55 minutes of cycling activity. We have shown how through systems engineering, integrating miniaturised electrical components, and by improving the micro-fluidic chip characteristics, the wearability, reliability and performance of the micro-fluidic platform was significantly improved
Exploring the effect of the pH on the corrosion of multilayer nickel-chromium coatings
No full textThe impact of the pH on the corrosion of microporous nickel-chromium coatings has been explored at localised scale by Scanning Electrochemical Microscopy and validated by potentiodynamic polarisation measurements. Results not only reveal the correlation between both techniques but also enables to identify the different corrosion rate after increasing the electrolyte aggressiveness varying the pH. However, independently of the pH, a similar corrosion mechanism was determined: the cross-section micrographs (by Field Emission-Scanning Electron Microscope) have revealed an isotropic growth of the actives sites at early-stage corrosion as well as the attack of different nickel layers during the corrosion propagation.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Yaiza Gonzalez Garci
Il dibattito italiano su principi e clausole generale e l'ideale della certezza del diritto
No full textThis essay provides a critical assessment of the current Italian debate on general clauses and principles as set forth in a recent book edited by Giovanni D’Amico. The Author focuses on the role that legal certainty has played so far in this discussion and suggests that its impact on real life decisions and the functioning of the legal system has been greatly undervalued. The essay’s central argument attempts to demonstrate that, in the interpretation of general clauses and their translation into specific rules, the objective of legal certainty should be pursued and can ultimately be achieved
Dynamics of Network Formation Processes in the Co-Author Model
No full textThis article studies the dynamics in the formation processes of a mutual consent network in game theory setting: the Co-Author Model. In this article, a limited observation is applied and analytical results are derived. Then, 2 parameters are varied: the number of individuals in the network and the initial probability of the links in the network in its initial state. A simulation result shows a finding that is consistent with an analytical result for a state of equilibrium while it also shows different possible equilibria.Dynamics, Network, Game Theory, Model,Simulation, Equilibrium, Complexity
