The marginalisation of bicycling in Modernist urban transport planning

This article deals with the scientific factors that have contributed to the dominance of motorised transport and the development of theoretical approaches in transport planning. Connections are made to modernism and to the theories within the field of transport planning that have created today’s transport systems. Connections are then made to the field of bicycle planning. It is argued that there

Austrian lichenologists exploring the Alps

Biographic sketches are provided for 19 of Austrian botanists who contributed in different ways to the knowledge on lichens of the European Alps: Othmar Breuss, Carl Wilhelm von Dalla Torre, Helmut Gams, Georg Gärtner, Martin Grube, Josef Hafellner, Karl von Keissler, Ernst Kernstock, Helmut Mayrhofer, Walter Obermayer, Josef Poelt, Karl Redinger, Julius Steiner, Elfriede Stocker-Wörgötter, Elisab

Filling gaps in measured discharge series with model-generated series

Abstract in UndeterminedGaps in measured discharge series are common in Iceland, especially during winter, but reconstructed series are needed for a number of applications. Modeled series are therefore sometimes used to fill the gaps to create a continuous series, but the modeled inserts may have different statistical characteristics from the observed series, whilst their initial and final values

The importance of personality, IQ and learning approaches : Predicting academic performance

Popular Abstract in Swedish Personlighetspsykologer har i mer än ett århundrade försökt att identifiera och beskriva observerbara skillnader mellan individer. Bland dessa indiduella skillnader har intelligens och personlighet fått stor uppmärksamhet inom skolvärlden, liksom elevers förhållningssätt till sitt lärande. Kunskapen om vilka faktorer som påverkar studieresultat har viktiga praktiska konThe aim of the present doctoral thesis was to examine to what extent personality traits and approaches to learning contribute to academic performance in upper secondary school (high school), after controlling for the well-known fact that general intelligence accounts for a large part of the variance. The general proposition of the thesis is that personality traits are stable dispositons and theref

Comparison of end-point continuum-solvation methods for the calculation of protein-ligand binding free energies.

We have compared the predictions of ligand-binding affinities from several methods based on end-point molecular dynamics simulations and continuum solvation, i.e. methods related to MM/PBSA (molecular mechanics combined with Poisson-Boltzmann and surface area solvation). Two continuum-solvation models were considered, viz. the Poisson-Boltzmann (PB) and generalised Born (GB) approaches. The non-el

On the Structure of Subordinate Clauses in Swedish

This paper presents a novel observation on Swedish subordinate clause structure. I show that in embedded V2 clauses, negation may only precede quantified subjects in the position following the complementizer; this is the very same limitation as found in the first position of main clauses. This correlation I take to provide a strong argument for assuming V-to-C movement in embedded V2 clauses. This

Electrophysiology, Optical Coherence Tomography and Molecular Genetic Analysis in Patients with Glaucoma and/or Best Vitelliform Macular Dystrophy as Part of Clinical Care

Glaucoma is a common ophthalmic disease with multifactorial aetiology. There is growing evidence that glaucoma is a disease of the entire retina and not only the inner retina. Best vitelliform macular dystrophy (BVMD) affects the retinal pigment epithelium and is considered a model system for the more common blinding disease, age-related macular degeneration. The aim of the work presented in this

Ethanol production in biorefineries using lignocellulosic feedstock - GHG performance, energy balance and implications of life cycle calculation methodology

Co-production of high-value biobased products in biorefineries is a promising option for optimized utilization of biomass. Lignocellulosic materials such as agricultural and forest residues have been identified as attractive alternative feedstocks because of their high availability and low resource demand. This study assessed the greenhouse gas (GHG) performance and energy balance of ethanol co-pr

Proposal for quantum spin tomography in ferromagnet-normal conductors

We present a theory for a complete reconstruction of nonlocal spin correlations in ferromagnet-normal conductors. This quantum spin tomography is based on cross-correlation measurements of electric currents into ferromagnetic terminals with controllable magnetization directions. For normal injectors, nonlocal spin correlations are universal and strong. The correlations are suppressed by spin-flip

Ethnobotanical notes from Daniel Rolander's Diarium Surinamicum (1754-1756): Are these plants still used in Suriname today?

The recent English translation of the diary of the Swedish naturalist Daniel Rolander (written 1754-1756) reveals the earliest records on useful plants of Suriname. Since he did not grant Linnaeus access to his specimens, Rolander never received credit for his work, part of his collection was lost, and his diary never published. Here we compare Rolander's notes with recent ethnobotanical data from

Transverse momentum dependence of eta meson suppression in Au plus Au collisions at root s(NN)=200 GeV

New measurements by the PHENIX experiment at the Relativistic Heavy Ion Collider for. production at midrapidity as a function of transverse momentum ((PT)) and collision centrality in root s(NN) = 200 GeV Au + Au and p + p collisions are presented. They indicate nuclear modification factors (R-AA) which are similar in both magnitude and trend to those found in earlier pi(0) measurements. Linear fi

Diagnostic accuracy of 3D color volume-rendered CT images for peroneal tendon dislocation in patients with acute calcaneal fractures

Background: Use of three-dimensional (3D) color volume-rendered (VR) images has been reported to be more time-efficient compared to that of cross-sectional computed tomography (CT) images for the diagnosis of peroneal tendon dislocation. However, the diagnostic performance of this technique has not been studied. Purpose: To test diagnostic accuracy of 3D color VR CT images of ankle for peroneal te

Time-resolved investigation of nanometer scale deformations induced by a high flux x-ray beam

We present results of a time-resolved pump-probe experiment where a Si sample was exposed to an intense 15 keV beam and its surface monitored by measuring the wavefront deformation of a reflected optical laser probe beam. By reconstructing and back propagating the wavefront, the deformed surface can be retrieved for each time step. The dynamics of the heat bump, build-up and relaxation, is followe

A numerical model of beach morphological evolution due to waves and currents in the vicinity of coastal structures

A numerical model was developed of beach morphological evolution in the vicinity of coastal structures. The model includes five sub-models for random wave transformation, surface roller development, nearshore wave-induced currents, sediment transport, and morphological evolution. The model was validated using high-quality data sets obtained during experiments with a T-head groin and a detached bre

Knowledge Maturity as a Means to Support Decision Making During Product-Service Systems Development Projects in the Aerospace Sector

Streamlining new product development forces companies to make decisions on preliminary information. This article considers this challenge within the context of project management in the aerospace sector and, in particular, for the development of product-service systems. The concept of knowledge maturity is explored as a means to provide practical decision support, which increases decision makers’
