Professioneller Konzeptwechsel zum Thema Neuromythen in der universitären Lehramtsausbildung Biologie
(Waxmann, 2018)
Sowohl angehende als auch praktizierende Lehrkräfte glauben z.B. an die Existenz von Lerntypen oder die Effektivität von Brain-Gym. Dabei handelt es sich um Neuromythen, d.h. Alltagskonzepte zum Thema Lernen und Gedächtnis. Im Rahmen dieses Beitrags wird beschrieben, ob und inwiefern eine nach dem Modell des professionellen Konzeptwechsels entwickelte Lernumgebung, die Zustimmung zu Neuromythen bei Studierenden reduzieren kann. Der Fokus dieses Beitrags liegt auf dem Element Reflexion mittels Konzeptwechseltexten. ...

Lernen mittels Konzeptwechsel in der Hochschuldidaktik
(Waxmann, 2018)
Im vorliegenden Beitrag wird das Lehr-Lernmodell des Konzeptwechsels (Conceptual Change) vom schulischen auf den universitären Kontext, bzw. auf die erste Phase der Lehrerbildung übertragen. Es wird beschrieben, welche Arten von Präkonzepten bei angehenden Lehrkräften bestehen können und vor dem Hintergrund professioneller Kompetenz ausgeführt, welche Folgerungen sich für die Lehrerbildung ableiten lassen. Auf der Basis eines Modells zum professionellen Konzeptwechsel werden Bedingungen und Ziele des Konzeptwechsels ...

Rethinking the genus Hyphodontia s.l. (Hymenochaetales, Basidiomycota) – investigations on a worldwide scope including new taxonomy, phylogeny, and identification keys
(2018-12)
The dissertation “Rethinking the genus Hyphodontia s.l. (Hymenochaetales, Basidiomycota) – investigations on a worldwide scope including new taxonomy, phylogeny, and identification keys” was elaborated by Janett Riebesehl in the Department of Ecology at the University of Kassel.
Changing the classification system of the fungal genus Hyphodontia s.l. to treat the species from the broad Hyphodontia s.l. concept by a division into other genera was continued. Hjortstam and Ryvarden (2002, 2009) began the concept, but ...

Role of Pseudouridine Formation by Deg1 for Functionality of Two Glutamine Isoacceptor tRNAs
(2017-01-26)
Loss of Deg1/Pus3 and concomitant elimination of pseudouridine in tRNA at positions 38 and 39 (ψ38/39) was shown to specifically impair the function of tRNAGlnUUG under conditions of temperature-induced down-regulation of wobble uridine thiolation in budding yeast and is linked to intellectual disability in humans. To further characterize the differential importance of the frequent ψ38/39 modification for tRNAs in yeast, we analyzed the in vivo function of non-sense suppressor tRNAs SUP4 and sup70-65 in the absence ...
Dissertation
Quantum optimal control theory of photoelectron spectroscopy
(2018)
The object of this doctoral thesis is two-fold and can be classified into two, but intrinsically related categories: (i) development of theoretical models for the simulation of electron dynamics and in parallel to this, (ii) method development of efficient numerical algorithms for ad hoc control of photoelectron and photoion-related observables. The first category primarily focuses on the development of a variety of theoretical models describing the interaction of light and matter for the extraction and control of ...

The Navier-Stokes equations with time discretisation and Lagrangian approximation
(2018)
In the present thesis, we combine the Navier-Stokes equations - which correspond to the so-called Eulerian representation of fluid flow - with the Lagrangian description of fluid flow.

S-Adenosyl-L-Homocysteine Hydrolase Inhibition by a Synthetic Nicotinamide Cofactor Biomimetic
(2018-03-21)
S-adenosyl-L-homocysteine (SAH) hydrolases (SAHases) are involved in the regulation of methylation reactions in many organisms and are thus crucial for numerous cellular functions. Consequently, their dysregulation is associated with severe health problems. The SAHase-catalyzed reaction is reversible and both directions depend on the redox activity of nicotinamide adenine dinucleotide (NAD+) as a cofactor. Therefore, nicotinamide cofactor biomimetics (NCB) are a promising tool to modulate SAHase activity. In the ...

Preferential weakening of rotational magnetic anisotropy by keV-He ion bombardment in polycrystalline exchange bias layer systems
(2018-05-04)
The consequences of keV light-ion bombardment of polycrystalline exchange bias layer systems on individual magnetic anisotropies composing the effective unidirectional magnetic anisotropy are investigated by vectorial magneto-optic Kerr effect measurements. Preferential reduction of rotatable magnetic anisotropy as compared to the other magnetic anisotropies is observable, disproving the intuitive assumption of an equable weakening of all magnetic anisotropies due to the bombardment. It is concluded that light-ion ...

Investigation of diamond nanostructures with incorporated color centers
(2018)
Diamond is a material with excellent properties due to its structure and composition. Its crystal lattice is a perfect host of different defect centers, so-called color centers, whose properties, especially the capability of emitting single photons, can serve in quantum information technologies (QIT). As a high refractive index material only a small part of the photons emitted by these color centers in diamond can be collected. To enhance the photon collection efficiency photonic structures are necessary. They can ...
