Abundances for the elements W, Os, and Bi are presented for the HgMn star chi Lupi, based upon GHRS echelle-mode spectra and a synthetic spectrum analysis. The tungsten abundance is consistent with a solar-system value while the osmium and bismuth abundances reflect enhancements. With these new data we are able to quantitatively define an abundance peak within the element range Z = 74 through 83.
The purpose of this paper is to examine how behavioural biases affect consumers’ response to energy-use information provided through smart meters (SM). We take insights from behavioural economics and carry out two real-life experiments with SMs and electricity users. The experiments were conducted in Copenhagen (Denmark) to identify and assess the potential of two economic behavioural biases, sali
We have experimentally studied the conditions for acoustic particle focusing inside aqueous droplets in two-phase-systems, and confirmed our findings by theoretical analysis. The results show that the acoustic properties of the two fluids have to be matched to achieve strong acoustic resonance and focusing in the system.
We derive an expression for the acoustic force density acting on an inhomogeneous fluid with a continuous spatial variation in density and compressibility. A key prediction of our theory, validated by confocal imaging in an acoustofluidic microchip, is that inhomogeneous fluid configurations can be stabilized in the presence of destabilizing forces due to gravity or acoustic streaming flows.
This abstract reports a novel acoustofluidic method to measure the hematocrit level of a whole blood sample within 20 seconds. The method is substantially faster than conventional centrifugation methods, has no moving parts and can be fully automated and integrated with further unit operations for analysis of blood samples at the point of care [1].
We present a fabrication scheme of contacting arrays of vertically standing nanowires (NW) for LEDs (Duan et al. Nature 409:66–69, 2001), photodetectors (Wang et al. Science (NY) 293:1455–1457, 2001) or solar cell applications (Wallentin et al. Science (NY) 339:1057–1060, 2013). Samples were prepared by depositing Au films using nano-imprint lithography (Ma rtensson et al. Nano Lett 4:699–702, 200
The current generation of dynamic invariant detectors often produce invariants that are inconsistent with program semantics or programmer knowledge. We improve the consistency of dynamically discovered invariants by taking into account higher-level constraints. These constraints encode knowledge about invariants, even when the invariants themselves are unknown. For instance, even though the invari
My focus is on aggregation of individual value rankings of alternatives to a collective value ranking. This is compared with aggregation o individual prefrences to a collective preference. While in an individual preference ranking the alternatives are ordered in accordance with one’s preferences, the order in a value ranking expresses one’s comparative evaluation of the alternatives, from the best
An acoustofluidic device, consisting of a polymer chip with a long straight channel, coupled to a piezoelectric transducer is modeled numerically in three dimensions and compared to experimental results in terms of the electric admittance as well as the ability to focus particles. In our experiments we obtain good acoustic particle focusing at a frequency of f = 1.14 MHz with an actuation voltage
Under de senaste 150 åren har det svenska landskapet genomgått mycket stora förändringar. Det har lett till förlust av livsmiljöer för många arter och har haft långtgående konsekvenser för vår inhemska fauna och flora. Många arter har minskat dramatiskt och i vissa fall helt försvunnit.När en art väl har börjat minska finns det många faktorer som kan förstärka den negativa trenden. En individrik p
Aim/hypothesis: Environmental factors are believed to contribute to the risk of developing type 1 diabetes. The aim of this study was to investigate how size for gestational age affects the risk of developing childhood type 1 diabetes. Methods: Using the Swedish paediatric diabetes quality register and the Swedish medical birth register, children with type 1 diabetes diagnosed between 2000 and 201
Uppsatsen syftar till att undersöka vilken roll den gode mannen för ensamkommande barn har när barnet ifråga är föremål för tvångsomhändertagande. Uppsatsen börjar med en definition av vilka som räknas som ensamkommande barn och vilka bestämmelser som finns kring dessa. Därefter går jag igenom den gode mannens roll och uppdrag och jämför med andra gode män. Sedan går jag kort igenom parters rättigThis essay aims to investigate the role of the guardian appointed to unaccompanied minors in Sweden, especially what role they have in cases of compulsory care. The essay defines unaccompanied minors and explores what regulations there are for them and investigates the role of the guardian compared to other representatives in Swedish law. The rights of the parties in the Swedish Care of Young Pers
In this essay, the feminine ideals in Virginia Woolf’s To the Lighthouse, Doris Lessing’s “To Room Nineteen” and Alice Munro’s “Too Much Happiness” are analysed and compared to the ideal of the Angel in the House – an ideal that originates from Coventry Patmore’s poem The Angel in the House and was popularised by Virginia Woolf’s paper “Professions for Women”. In addition, the consequences of this
Purpose: The aim of this paper is to compare the Nation Branding initiatives of Sweden and Germany in order to identify important factors while navigating their Nation Brand. A framework has been developed on the basis of existing theory which has been tested on the objects of the case study. The purpose was to demonstrate possible empirical correlations not described by the theory. Finally the pa
The result of this research is, that the Kennedy myth lived in a symbiotic relationship with the political mission of John F Kennedy during his time in the White House. The myth was as present – as the real politics of Kennedy – during his presidency. The Kennedy myth was a tool for John Kennedy to reach the White House. This myth was natural in a country as America, where the American Dream is fu
