The mechanism of the reaction of ketene with hydroxyl radical has been studied by ab initio CCSD(T)-F12/cc-pVQZ-F12//B3LYP/6-311G(d,p) calculations of the potential energy surface. Temperature- and pressure-dependent reaction rate constants have been computed using the RRKM-Master Equation and transition state theory methods in the temperature range of 300–3000 K and in the pressure range of 0.01–

Objectives: The pediatric vestibular assessment has developed significantly in the past two decades, especially in terms of assessment of cochlear implant (CI) candidates. Different methods and test protocols have been applied, however without a general consensus. We present here the feasibility, validity and reliability of a child friendly vestibular testing in use at our department for the asses

På senare år har jag funderat över det faktum att jag och många av mina kollegor undervisar i att hitta och utveckla den egna rösten. Samtidigt som jag känner mig trygg i min roll som lärare och upplever att jag har lätt för att vara konstruktiv i en undervisningssituation har jag också slagits av det motsägelsefulla i att undervisa någon annan i någonting som är så personligt.Hur kan jag hjälpa n

Measuring fibre dispersion in white matter with diffusion magnetic resonance imaging (MRI) is limited by an inherent degeneracy between fibre dispersion and microscopic diffusion anisotropy (i.e., the diffusion anisotropy expected for a single fibre orientation). This means that estimates of fibre dispersion rely on strong assumptions, such as constant microscopic anisotropy throughout the white m

Dropwise condensation has drawn significant attention due to its efficient heat transfer performance compared to filmwise condensation. In this paper, typical experimental data for dropwise condensation on smooth hydrophobic surfaces were collected as well as the typical available heat transfer models. The comparisons between the prediction results and the experimental data indicated that the exis

In this paper, we propose a method for adaptive selection of the kernel size used in estimation of the wall shear stress (WSS) based on flow velocity profiles obtained by the blood flow imaging method based on enhancement of RF echo signals from blood cells using a singular value decomposition based clutter filter. Two simulation phantom experiments with the Field II program were performed to vali

Last decades' non-western immigration to Europe has resulted in culturally and religiously more diverse populations in many countries. One manifestation of this diversification is new features in the cityscape. Using a quasiexperimental approach, in which an unexpected political process that led way to the first public call to prayer from a mosque in Sweden is combined with rich, daily, informatio

This research examines the degree to which legislators respond to their districts by analyzing immigration‐related legislative speeches from the Swedish parliament (2005–16). Using a text‐scaling method, we find that the immigration discourse fluctuates between “socioeconomic responsibility” and “cultural difference” poles. We argue that socioeconomic declines and extreme‐right party success serve

Institutional economics has produced a string of findings about the importance of good institutions for economic growth and development. While consensus is lacking about how important institutions are, few scholars argue that institutions have no impact whatsoever. Yet, for all the knowledge produced, the results of institutional reforms are meager. This is not surprising as a central theme in the

Predicting the dynamics of biotic communities is difficult because species’ environmental responses are not independent, but covary due to shared or contrasting ecological strategies and the influence of species interactions. We used latent-variable joint species distribution models to analyze paired historical and contemporary inventories of 585 vascular plant species on 471 islands in the southw

10Be in ice cores has been instrumental for reconstructing past changes in solar activity prior to direct observations. For a robust use of these records, it is pivotal to understand the 10Be transport and deposition. However, there are only few high-resolution seasonal 10Be data longer than one full solar cycle (11 years) that could enable a quantification of the influences of atmospheric circula

BACKGROUND: TKA generally has excellent long-term survivorship. When a new knee system supersedes a previous model, increased survivorship, improved functional performance, or both may be expected, because key areas of design modification are often targeted to address wear, stability, and the patellofemoral articulation. However, not all design changes are beneficial, and to our knowledge, knee ar

Although there is extensive research indicating the vital role of functional emotion regulation (ER) in healthy psychological development, such research has neglected examination of adolescents. One potential reason for this neglect is the lack of valid ER instruments developed specifically for adolescents. Further, the available ER instruments for adolescents usually require elaborate forms of co

This article presents practice-theoretical conceptions of societal relations to nature as a fruitful alternative to common system approaches in social-ecological research. Via the example of plastic food packaging, two different practice-theoretical approaches to food supply are discussed regarding their suitability for relating the material properties of packaging to their everyday use by produce
