Hjalmar Meissner (1885-1940)
No full textCarl Hjalmar Meissner was born 1 March 1865 in Helsinki, Finland and died 28 May 1940 in Stockholm. He was a Finnish-Swedish pianist, conductor, arranger, composer and author. As a conductor, he worked mainly as a bandleader for military music and theatre ensembles, but also as an opera and symphony orchestra conductor. His profession as a composer arose mostly from his work as pianist and conductor. He was married to operetta singer Emma Meissner in 1899.</p
Observation and control of hybrid spin-wave-Meissner-current transport modes
No full textSuperconductors are materials with zero electrical resistivity and the ability to expel magnetic fields, which is known as the Meissner effect. Their dissipationless diamagnetic response is central to magnetic levitation and circuits such as quantum interference devices. In this work, we used superconducting diamagnetism to shape the magnetic environment governing the transport of spin waves-collective spin excitations in magnets that are promising on-chip signal carriers-in a thin-film magnet. Using diamond-based magnetic imaging, we observed hybridized spin-wave-Meissner-current transport modes with strongly altered, temperature-tunable wavelengths and then demonstrated local control of spin-wave refraction using a focused laser. Our results demonstrate the versatility of superconductor-manipulated spin-wave transport and have potential applications in spin-wave gratings, filters, crystals, and cavities.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.QN/vanderSarlabQN/Kavli Nanolab DelftQN/Blanter Grou
What new cell biology findings could bring to therapeutics: is it time for a phenome-project in <i>Toxoplasma gondii</i>?
No full text"If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat" (SunTzu the Art of War, 544-496 BC). Although written for the managing of conflicts and winning clear victories, this basic guideline can be directly transferred to our battle against apicomplexan parasites and how to focus future basic research in order to transfer the gained knowledge to a therapeutic intervention stratey. Over the last two decades the establishment of several key-technologies, by different groups working on <i>Toxoplasma gondii</i>, made this important human pathogen accessible to modern approaches in molecular cell biology. In fact more and more researchers get attracted to this easy accessible model organism to study specific biological questions, unique to apicomplexans. This fascinating, unique biology might provide us with new therapeutic options in our battle against apicomplexan parasites by finding its Achilles' heel. In this article we argue that in the absence of a powerful high throughput technology for the characterisation of essential gene of interests a coordinated effort should be undertaken to convert our knowledge of the genome into one of the phenome
Invasion factors of apicomplexan parasites: essential or redundant?
No full textApicomplexa are obligate intracellular parasites that cause several human and veterinary diseases worldwide. In contrast to most intracellular pathogens these protozoans are believed to invade a rather passive host cell in a process, that is, tightly linked to the ability of the parasites to move by gliding motility. Indeed specific inhibitors against components of the gliding machinery and the analysis of knockdown mutants demonstrate a linkage of gliding motility and invasion. Intriguingly, new data show that it is possible to block gliding motility, while host cell invasion still occurs. This suggests that either the current models established for host cell invasion need to be critically revised or that alternative, motor independent mechanisms are in place including a more active role of the host cell that can complement a missing actin-myosin-system. Here we discuss some of the discrepancies that need to be addressed for a better understanding of invasion. © 2013
The use of the special theory of relativity for the Meissner Effect in superconductor
No full textThe electromagnetic waves are considered in this article as the mediators of interaction in the Meissner Effect or the diamagnetic property of the superconductors. During the cooling of a superconductor electromagnetic waves may be released when the electrons occupy lower states of the energy. These electromagnetic waves may combine in circularly, elliptically and spherically rotating ways, being called in this article the rounded electromagnetic fields. The application of the Lorentz transformation of the Special Theory of Relativity to the magnetic vectors of the mediating electromagnetic fields implies the magnetic orthogoniopedic effect inside the bulk of a superconductor in the Meissner Effect.PhysicsApplied Science

StatusDiversity: Methoden der Datenerhebung
No full textIn diesem Teilbericht wird die Entwicklung des innovativen Interviewinstruments digital-narrative- photo-elicitation (DNP) zur Erhebung von Migrations-Status-Geschichten beschrieben. Die im Rahmen des Forschungsprojektes StatusDiversity angelegte Forschung will durch die Rekonstruktion individueller Migrations-Status-Geschichten besser verstehen, wie räumlich und zeitlich differenzierte Muster von legal status diversity entstehen (Meissner 2017). Neben der reinen Entwicklung der DNP wird auch das Vorgehen bei der methodischen Realisierung der Datenerhebung reflektiert, insbesondere der Zugang zu und die Auswahl von InterviewpartnerInnen. Abschließend wird das Vorgehen zur Auswertung der mit Hilfe der DNP gesammelten Daten erläutert.OLD Urban Renewal and Housin

The electric "Meissner effect" in spin superconductor
No full textSpin superconductivity results from the condensation of spin-triplet but charge neutral particles (e.g., triplet excitons). We present a Laplace-type equation describing electrostatic properties of spin superconductors. With the phenomenological equations obtained, we show that there exists an electric "Meissner effect" against the spatial variation of the electric field along the magnetic moment direction, in particular, ((s) over cap . del) ((s) over cap . E). Several distinctive characteristics of this electric "Meissner effect" emerge in pin superconductors. Firstly, the variation of the electric field ((s) over cap . del)((s) over cap . E) has an abrupt decrease at the boundary, which is analogous to the screen effect for electric field E in a uniform dielectric material. Secondly, the super-spin current distributes inside or near the boundaries of a spin superconductor, which depends on the magnitude of gradient for the external driven electric field.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000327895600004&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, Condensed MatterSCI(E)EI0ARTICLE12null8
