Säugetiere, Fisch-Otolithen, Ostracoden, Mollusken und Charophyten aus den Süßwasser- Schichten (Oligozän) von Wolfsheim im Mainzer Becken
2000
The Suswasser-Schichten (Freshwater Beds) (Oligocene) in the Mainz Basin are a paleontologically poorly studied formation. A succession of predominantly lacustrine marls from Wolfsheim can be attributed to the Suswasser-Schichten on basis of a palaeoecological and biostratigraphic analysis of its mammal teeth, fish otoliths, ostracods, mollusks, foraminifera and charophytes. The occurrence of the mammal speciesToeniodus aff.hexalophodus andIssiodoromys minor (primitive form) enables an attribution of the Suswasser-Schichten to the reference level MP 24 of the eurasiatic mammal biostratigraphic zonation. As the reference fauna of level MP 24 is believed to occur in a lithostratigraphically m…
Foreldres opplevelse av tillit og tap når barnet er til anestesi : Hvordan opplever foreldre det å være med på barnets første generelle anestesi ved …
2018
Masteroppgave spesialsykepleie ME519 – Universitetet i Agder 2018 Background There is a widespread practice that one parent is present during the induction of his or her child’s anesthesia. There are quantitative studies on how the parent’s presence impacts the induction, the impact on the child, and satisfaction with the parents. Literature within psychology states that there are bonds between parent and child. However, I found little on what the parents’ experiences are. Aim The intention of this study is to gain a better understanding of the parent’s experiences when they are following their child to, and attending, the induction of the general anesthesia. The research question What is t…
Balancing the Frame of Threat: Uninvited Migrants in the Finnish News
2010
This chapter analyzes Finnish news journalism concerning asylum seekers and undocumented migration. It focuses on 'the variety of others', the media not only construct a division between 'us' and 'them,' but also create varieties of 'others.' The solution to the problems related to otherness is not, however, to recognize that we are all different, as the currently popular discourse that celebrates 'cultural diversity' often claims. This chapter scrutinizes the frames of 'threat' and 'victim' which are typical of the media’s coverage of asylum seekers and undocumented migrants. To identify the narrative, I have analyzed what is defined as problems and what is offered as the causes of and sol…

On the shell structure and geometry of monovalent metal clusters
1991
The Huckel model is used to study the electronic structure of monovalent metal clusters. In an fcc cluster the Huckel model gives an estimate to the electronic structure of a free electron cluster. It is shown that the surface faceting of the fcc cluster can destroy the electronic shell structure already when the cluster has about 100 electrons. In the Huckel model the icosahedral structure has smaller total energy than the fcc structures, from which the Wulff construction has the smallest energy already when the cluster has 600 atoms.
Edge-dependent selection rules in magic triangular graphene flakes
2008
The electronic shell and supershell structure of triangular graphene quantum dots has been studied using density functional and tight-binding methods. The density functional calculations demonstrate that the electronic structure close to the Fermi energy is correctly described with a simple tight-binding model, where only the ${p}_{z}$ orbitals perpendicular to the graphene layer are included. The results show that (i) both at the bottom and at the top of the ${p}_{z}$ band, a supershell structure similar to that of free electrons confined in a triangular cavity is seen, (ii) close to the Fermi level, the shell structure is that of free massless particles, (iii) triangles with armchair edge…

Economic freedom and fundamental rights: freedom to conduct business in the multilevel european legal system
2012
La libertad de empresa es utilizada como pretexto para ilustrar las relaciones y jerarquías entre libertades económicas comunitarias y derechos fundamentales en el ordenamiento multinivel europeo. Su estrecha relación con las libertades económicas comunitarias y con el objetivo del mercado interior, han dotado a la libertad de empresa de una especial fortaleza a la hora de dirimir sus eventuales conflictos con otros derechos acogidos aparentemente en pie de igualdad en la reciente redefinición de los objetivos de la UE. Por otro lado, cuando esta primacía se transplanta al ordenamiento interno se corre el riesgo de alterar los equilibrios del sistema de derechos de los Estados, anclados …
Improvement of Hall Effect Current Transducer Metrological Performances in the Presence of Harmonic Distortion
2010
The performance of Hall effect current transducers (HECTs), under distorted waveform conditions, is usually characterized by means of a frequency response test. In this paper, it was investigated if frequency response is able to correctly evaluate the ratio and the phase errors under distorted conditions. Two HECTs, with the accuracy class level of 1% and 0.5%, respectively, were experimentally characterized under two conditions: 1) sinusoidal excitation with frequencies ranging from 50 to 750 Hz, which is the well-known frequency response test, and 2) nonsinusoidal excitation using fundamental frequency and one harmonic with adjusted amplitude and phase shift. It was found that ratio and p…
Self-Assembly-Directed Organization of a Fullerene–Bisporphyrin into Supramolecular Giant Donut Structures for Excited-State Charge Stabilization
2021
Functional materials composed of spontaneously self-assembled electron donor and acceptor entities capable of generating long-lived charge-separated states upon photoillumination are in great demand as they are key in building the next generation of light energy harvesting devices. However, creating such well-defined architectures is challenging due to the intricate molecular design, multistep synthesis, and issues associated in demonstrating long-lived electron transfer. In this study, we have accomplished these tasks and report the synthesis of a new fullerene–bis-Zn-porphyrin e-bisadduct by tether-directed functionalization of C60 via a multistep synthetic protocol.
