TY - THES A1 - Krause, Susen T1 - LOCKDOWN: a documentary about the corona crisis in the Philippines N2 - Isolierung, finanzielle Not und Zukunftsängste: Die sozialen Folgen des Corona-Lockdowns sind gravierend. 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 längsten und härtesten Lockdowns der Welt. Im internationalen Vergleich fällt auf, dass der Ton, den der Präsident anschlägt, besonders rau ist und die Einschränkungen 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. Aus Sicht der Befragten wird eine multiperspektivische Geschichte erzählt, die von dem Lockdown und seinen Folgen auf der philippinischen Insel Boracay handelt.

JF - Microchemical Journal N2 - Electronic cigarettes (e-cigarettes) have become popular worldwide with the market growing exponentially in some countries. 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.

T1 - Magnetic Fields and Induced Voltages in case of a Direct Strike - Comparison of Results obtained from Measurements at a Scaled Building to those of IEC 62305-4 N2 - In the paper the results obtained from experiments at a modelled reinforced building in case of a direct lightning strike are compared with calculations. 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.

T1 - Magnetic Fields and Induced Voltages inside LPZ 1 Measured at a 1:6 Scale Model Building N2 - Laborexperimente zu Blitzschutzzonen in Stahlbetongebäuden anhand eines Modells im Maßstab 1:6 N2 - For the application of the concept of Lightning Protection Zones (LPZ), the knowledge of the magnetic fields and induced voltages inside a structure is necessary. Laboratory experiments have been conducted at a downscaled model of a building (scale factor 1:6) to determine these electromagnetic quantities in case of a direct strike to the structure. The model (3 m x 2 m x 2 m) represented a small industrial building using the reinforcement of the concrete as electromagnetic shield. The magnetic fields and magnetic field derivatives were measured at several location inside the scaled model. Further, the voltages induced on three typical cable routes inside the model was determined. The influence of the lightning current waveshape, point-of-strike, bonding of the cable routes, and bridging of an expansion joint in the middle of the building on these quantities was studied.

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.

Im Dialog stehen sich Individuen in ständiger Beeinflussung gegenüber. Das Wissen darum kann bewusst (aus)genutzt werden und den Gesprächspartner zu „unbewusstem“ Handeln verleiten. Eine entsprechende Nutzung zum eigenen Vorteil bezeichnet man als Manipulation. Es soll bei Jugendlichen ein Bewusstsein geschaffen werden, um gezielt Manipulation zu erkennen. Erstellt wird hierfür eine Installation im Raum mit einer abstrahierten, metaphorischen Darstellung von Manipulation. Die Jugendlichen erfahren sich im interaktiven Part einerseits in der Situation eines Manipulationsopfers und andererseits als Manipulant. Die begehbare Station vermittelt über die Räumlichkeit das Gefühl der Bedrängnis und erzeugt auf plakative Weise eine körperliche Erfahrung einer Bredouille, die im psychischen Zusammenhang zu Manipulation steht.

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.
