This paper presents a mathematical approach and numerical model that simulates beach and dune change in response to cross-shore processes of dune growth by wind and dune erosion by storms, and by gradients in longshore sand transport that will alter shoreline position. Sub-aerial transport processes are represented, whereas sub-aqueous transport is neglected. The system is tightly coupled morpholo

This article is a way to try to concretize the so-called new economy based on a couple of concrete expressions. The concepts of cultural heritage and consumption are used to describe and analyse some specific service operations in a couple of Swedish retailers. In both are the products manufactured, in one case, stone-baked sourdough bread and in the other handmade chocolates with reference to tra

This paper investigates how river privatisation in Turkey is deployed to expand renewable energy production and the implications this has for issues of ownership, rights to water and community life. Recent neoliberal reforms in Turkey have enabled the private sector to lease the rights to rivers for 49 years for the sole purpose of electricity production. The paper focuses on the re-scaling and re

Objective: The purpose of this study was to describe procedural changes in hospital incident investigations and show the consequences of these changes over time. Methods: A two-stage method was used. First component of the study was a content analysis of 87 incident investigations conducted 1995-2014 by the regulatory authority after adverse events in a Swedish university hospital. Second compone

The origin behind the dipolar order in molecular fluids is investigated by using a simple dipolar fluid and Monte Carlo simulation technique. A penalty function is employed to separately manipulate the positional and orientational structure of the fluid. By considering the distance-dependent Kirkwood function G (k), which in turn is related to the dielectric permittivity of the fluid, it is observ

There are emerging data to support a role for genetic and immune-related factors in the pathogenesis of lymphoplasmacytic lymphoma/Waldenstrom's macroglobulinemia. In this article, we review our recently published, large, population-based studies using data from Sweden and from United States veterans and propose mechanisms and pathways underlying our observations. We also discuss future directions

A comment on [W.J. Olds, A.R. McKinley, M.R. Moore, M.G. Kimlin, In vitro model of vitamin D(3) (cholecalciferol) synthesis by UV radiation: Dose-response relationships, J. Photochem. Photobiol. B: Biol. 93 (2008) 88-93]. The article also discusses some related issues.

Cross sections for elastic and proton-dissociative photoproduction of J/psi mesons are measured with the H1 detector in positron-proton collisions at HERA. The data were collected at ep centre-of-mass energies root s approximate to 318 GeV and root s approximate to 225 GeV, corresponding to integrated luminosities of L = 130 pb(-1) and L = 10.8 pb(-1), respectively. The cross sections are measured

This report summarizes some of the results of studies in our laboratory exploring the development of cognitive, reading and prosodic skills in children with cochlear implantation (CI). The children with CI performed at significantly lower levels than the hearing comparison group on the majority of cognitive tests, despite showing levels of nonverbal ability. The differences between children with C

Background: The intervention; "Continuum of Care for Frail Older People", was designed to create an integrated continuum of care from the hospital emergency department through the hospital and back to the older person's own home. The aim of this study is to evaluate the effects of the intervention on functional ability in terms of activities of daily living (ADL). Methods: The study is a non-blind

The behavior of the surviving population of Lactobacillus plantarum 564 growing in MRS broth after pulsed electric field (PEF) treatments of different intensities was monitored by isothermal calorimetry, optical density and plate counts. Bacterial cells were treated with monopolar square pulses at varying nominal electric field strengths and number of pulses, corresponding to applied energies of 3

The Swedish Board of Fire Research has initiated a pre-study to investigate the possibility to setup a larger research project that would deal with residential fires. Through interviews, literature studies and an initial statistical study, it is clear that there is a need for an umbrella project that focuses on residential fires. The major reason for doing this it that the costs of residential f

Two-dimensional electronic spectroscopy (2D) has been applied to beta-carotene in solution to shine new light on the ultrafast energy dissipation network in carotenoids. The ability of 2D to relieve spectral congestion provides new experimental grounds for resolving the rise of the excited state absorption signal between 18,000 and 19,000 cm(-1). In this spectral region, the pump-probe signals fro

Insulin signaling to the brain is important not only for metabolic homeostasis but also for higher brain functions such as cognition. GABA (c-aminobutyric acid) decreases neuronal excitability by activating GABA(A) channels that generate phasic and tonic currents. The level of tonic inhibition in neurons varies. In the hippocampus, interneurons and dentate gyrus granule cells normally have signifi

Background: Software ecosystems emerged as means for several actors to jointly provide more value to the market than any of them can do on its own. Recently, software ecosystems are more often used to support the development of hardware-dependent solutions. Objectives: This work aims at studying barriers and bridges to participation in an ecosystem with substantial hardware dependencies. Method: W
