Oftmals wird der Fokus in der Pandemie auf die wirtschaftlichen Folgen und die Auslastung des Gesundheitssystems gelegt, doch die Auswirkungen des Shutdowns sind weitaus vielschichtiger. Die Philippinen hatten einen der l{\"a}ngsten und h{\"a}rtesten Lockdowns der Welt. Im internationalen Vergleich f{\"a}llt auf, dass der Ton, den der Pr{\"a}sident anschl{\"a}gt, besonders rau ist und die Einschr{\"a}nkungen des gesellschaftlichen Lebens strikt und gnadenlos sind. Der Dokumentarfilm „LOCKDOWN - a documentary about the corona crisis in the Philippines" gibt einen Einblick in das Leben der Betroffenen.

The absence of product standards and safety regulations requires urgent development of analytical methodologies for the holistic control of the growing diversity of such products. An approach based on low-field nuclear magnetic resonance (LF-NMR) at 80 MHz is presented for the simultaneous determination of key parameters: carrier solvents (vegetable glycerine (VG), propylene glycol (PG) and water), total nicotine as well as free-base nicotine fraction. Moreover, qualitative and quantitative determination of fourteen weak organic acids deliberately added to enhance sensory characteristics of e-cigarettes was possible. In most cases these parameters can be rapidly and conveniently determined without using any sample manipulation such as dilution, extraction or derivatization steps. The method was applied for 37 authentic e-cigarettes samples. In particular, eight different organic acids with the content up to 56 mg/mL were detected. Due to its simplicity, the method can be used in routine regulatory control as well as to study release behaviour of nicotine and other e-cigarettes constituents in different products.}, language = {en} } @inproceedings{HuberRauStreblowetal.2014, author = {Huber, Max and Rau, Sebastian and Streblow, Rita and Wollert, J{\"o}rg and M{\"u}ller, Dirk}, title = {L{\"u}ftungskan{\"a}le als Funkstrecke}, series = {Jahreskolloquium Kommunikation in der Automation (KommA 2014) : Lemgo, 18.11.2014 / J{\"u}rgen Jasperneite ...

The comparison includes peak values of the magnetic field Hmax, its derivative (dH/dt)max and of induced voltages umax in typical cable routings. The experiments are performed at a 1:6 scaled building and the results are extrapolated using the similarity relations theory. The calculations are based on the approximate formulae given in IEC 62305-4 and have to be supplemented by a rough estimation of the additional shielding effect of a second reinforcement layer. The comparison shows, that the measured peak values of the magnetic field and its derivative are mostly lower than the calculated. The induced voltages are in good agreement. Hence, calculations of the induced voltages based on IEC 62305-4 are a good method for lightning protection studies of buildings, where the reinforcement is used as a grid-like electromagnetic shield.}, subject = {Blitz}, language = {en} } @inproceedings{ZischankHeidlerWiesingeretal.2004, author = {Zischank, Wolfgang J. and Heidler, Fridolin and Wiesinger, J. and Stimper, K. and Kern, Alexander and Seevers, M.}, title = {Magnetic Fields and Induced Voltages inside LPZ 1 Measured at a 1:6 Scale Model Building}, year = {2004}, abstract = {Laborexperimente zu Blitzschutzzonen in Stahlbetongeb{\"a}uden anhand eines Modells im Maßstab 1:6}, language = {en} } @inproceedings{KatzWillner2006, author = {Katz, Eugenii and Willner, Itamar}, title = {Magneto-controlled quantized electron transfer to surface-confined redox units and metal nanoparticles}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:a96-opus-1528}, year = {2006}, abstract = {Hydrophobic magnetic nanoparticles (NPs) consisting of undecanoate-capped magnetite (Fe3O4, average diameter ca. 5 nm) are used to control quantized electron transfer to surface-confined redox units and metal NPs. A two-phase system consisting of an aqueous electrolyte solution and a toluene phase that includes the suspended undecanoatecapped magnetic NPs is used to control the interfacial properties of the electrode surface. The attracted magnetic NPs form a hydrophobic layer on the electrode surface resulting in the change of the mechanisms of the surface-confined electrochemical processes. A quinone-monolayer modified Au electrode demonstrates an aqueous-type of the electrochemical process (2e-+2H+ redox mechanism) for the quinone units in the absence of the hydrophobic magnetic NPs, while the attraction of the magnetic NPs to the surface results in the stepwise single-electron transfer mechanism characteristic of a dry nonaqueous medium. Also, the attraction of the hydrophobic magnetic NPs to the Au electrode surface modified with Au NPs (ca. 1.4 nm) yields a microenvironment with a low dielectric constant that results in the single-electron quantum charging of the Au NPs.}, subject = {Biosensor}, language = {en} } @misc{SteuerDankertBernhardLangolfetal.2022, author = {Steuer-Dankert, Linda and Bernhard, Sebastian and Langolf, Jessica and Leicht-Scholten, Carmen}, title = {Managing change and acceptance of digitalization strategies - Implementing the vision of „Internet of Production" (IoP) in existing corporate structures}, series = {Textile Impulse f{\"u}r die Zukunft: Aachen-Dresden-Denkendorf International Textile Conference 2022}, journal = {Textile Impulse f{\"u}r die Zukunft: Aachen-Dresden-Denkendorf International Textile Conference 2022}, pages = {153 -- 153}, year = {2022}, abstract = {The vision of the Internet of Production is to enable a new level of crossdomain collaboration by providing semantically adequate and context-aware data from production, development \& usage in real-time.}, language = {en} } @masterthesis{Blumenthal2021, type = {Bachelor Thesis}, author = {Blumenthal, Lea Katrin}, title = {Manipulation: Ein didaktisches interaktives Ausstellungskonzept}, publisher = {Fachhochschule Aachen}, address = {Aachen}, school = {Fachhochschule Aachen}, pages = {125 Seiten}, year = {2021}, abstract = {Bei dem Projekt handelt es sich um eine interaktive Station f{\"u}r Jugendliche mit dem Ziel, Manipulation im Alltag zu entlarven und mithilfe von konkreten Beispielen spielerisch zu lernen.

This power-matching problem can be solved with a balanced hybrid propulsion system. However, there is a trade-off between wing loading, power loading, the level of hybridization, as well as range and take-off distance. An optimization method can vary design variables in such a way that a minimum of a particular objective is attained. In this paper, a comparison between the optimization results for minimum mass, minimum consumed primary energy, and minimum cost is conducted. A new initial sizing algorithm for general aviation aircraft with hybrid-electric propulsion systems is applied. This initial sizing methodology covers point performance, mission performance analysis, the weight estimation process, and cost estimation. The methodology is applied to the design of a STOL general aviation aircraft, intended for on-demand air mobility operations. The aircraft is sized to carry eight passengers over a distance of 500 km, while able to take off and land from short airstrips. Results indicate that parallel hybrid-electric propulsion systems must be considered for future STOL aircraft.}, language = {en} }
