The growth of charged platelets

Growth models of charged nanoplatelets are investigated with Monte Carlo simulations and simple theory. In a first model, 2-dimensional simulations in the canonical ensemble are used to demonstrate that the growth of a single weakly charged platelet could be limited by its own internal repulsion. The short range attractive interaction in the crystal is modeled with a square well potential while th

Rituell och institutionell glömska

Rituell glömska gäller individen eller institutionen, som står inför Gud eller inför människor. Där ritualen erbjuder individen glömska inför Gud, kan skulden och straffet inför människor stå kvar. Detta tydliggörs i Strindbergs Påsk. I den romersk.katolska kyrkan är prästens fullmakt att avlösa inte, som i Svenska kkyrkan, given med prästvigningen, utan delegerad. Under högmedeltiden började man

A measurement-based fading model for wireless personal area networks

Personal area networks (PANs) are wireless communications systems with high data rates but small coverage area. PAN propagation channels differ from the well-explored propagation channels of wide-area networks due to several reasons: (i) the distances are typically very small, (ii) the antenna arrangements can be quite different, and (iii) the influence from human presence in the environment is di

Consequences of Inadvertent Radioiodine Treatment of Graves' Disease and Thyroid Cancer in Undiagnosed Pregnancy. Can We Rely on Routine Pregnancy Testing?

Introduction. Radioiodine and most cytostatic treatments are contraindicated in pregnancy. Still, inadvertent therapy does occur. Radioiodine was given to two pregnant women with Graves' disease and thyroid cancer respectively, both in their 20th gestational week. Routine pregnancy tests based on urinary β-hCG had failed to indicate pregnancy in both cases. Methods. Estimation of doses to the foet

Step dynamics and oxide formation during CO oxidation over a vicinal Pd surface.

In an attempt to bridge the material and pressure gaps - two major challenges for an atomic scale understanding of heterogeneous catalysis - we employed high-energy surface X-ray diffraction as a tool to study the Pd(553) surface in situ under changing reaction conditions during CO oxidation. The diffraction patterns recorded under CO rich reaction conditions are characteristic for the metallic st

A healthy diet with and without cereal grains and dairy products in patients with type 2 diabetes: study protocol for a random-order cross-over pilot study - Alimentation and Diabetes in Lanzarote -ADILAN.

Research on the role of nutrition in type 2 diabetes has largely focused on macro/micronutrient composition and dietary fiber intake, while fewer studies have tested the effects of differing food choice. Some observational studies and short-term intervention studies suggest that a food pattern mimicking the diet with which humans evolved positively influences glucose control and associated endocri

Metabolic effects of furaldehydes and impacts on biotechnological processes.

There is a growing awareness that lignocellulose will be a major raw material for production of both fuel and chemicals in the coming decades-most likely through various fermentation routes. Considerable attention has been given to the problem of finding efficient means of separating the major constituents in lignocellulose (i.e., lignin, hemicellulose, and cellulose) and to efficiently hydrolyze

Revisiting the classification of clinical phenotypes of anti-neutrophil cytoplasmic antibody-associated vasculitis: a cluster analysis

Background Granulomatosis with polyangiitis (Wegener's) (GPA) and microscopic polyangiitis (MPA) are subgroups of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) defined historically by clinical and histological features. GPA and MPA are heterogeneous entities with overlapping phenotypes. To identify novel subgroupings, cluster analysis was used to explore the phenotypic sp

Protest activity, social incentives, and rejection sensitivity: Results from a survey experiment about tuition fees

People may engage in protest activity either because of collective incentives or selective incentives, or a combination of them. In this study we focus on the selective incentives part of the calculus of political participation, particularly the impact of the social dimension. We hypothesize that people will participate in demonstrations or other forms of protest, to a higher extent if they ar

Iranian and Swedish adolescents: differences in personality traits and well-being

Introduction. This study addresses the need to further contextualize research on well-being (e.g., Kjell, 2011) in terms of cross-cultural aspects of personality traits among adolescents and by examining two different conceptualizations of well-being: subjective well-being (i.e., life satisfaction, positive and negative affect) and psychological well-being (i.e., positive relations with others, en

Risk Management and Quality Assurance through the Food Supply Chain – Case Studies in the Swedish Food Industry

Processed food and eating out of the home are increasing phenomena, which presents new business opportunities for food manufacturers. However, the new food products require increased quality and safety, and thereby a more controlled distribution. The overall purpose of the research presented in this article is to describe the food supply chain from a critical context point of view in order to high

Att bygga broar över kulturgränser : Om svenskars kommunikation med icke-svenskar vid arbete utanför Sverige

Popular Abstract in Swedish Den pågående globaliseringen skapar ett behov av ökad kommunikationskompetens bland svenskar som arbetar ute i världen. Denna studie baseras på beskrivningar av de kommunikationsprocesser som används av svenskar, när de möter icke-svenskar på yrkets vägnar vid arbete utanför Sverige. Beskrivningarna baseras på intervjuer. Studien är inriktad på tre områden. De kommunikaGlobalization creates a need for increased communication competence among Swedes working on the global arena. This study is based on reports of communication processes used by Swedes when interacting professionally with non-Swedes. The reports are derived from interviews. The study focuses on three areas. The communication strategies developed by the respondents for intercultural communication. Th

Interplay of Touschek scattering, intrabeam scattering, and rf cavities in ultralow-emittance storage rings

The latest generation of storage ring-based light sources employs multibend achromat lattices to achieve ultralow emittance. These lattices make use of a large number of weak bending magnets which considerably reduces the amount of power radiated in the dipoles in comparison to power radiated from insertion devices. Therefore, in such storage rings, parameters such as emittance, energy spread, and

Ventilerad luftspalt i yttervägg : luftomsättningar och konvektiv fukttransport

Allvarliga fuktproblem i ytterväggar med regelstomme av trä och fasadskikt av puts på isolering har under senare delen av 2000-talet konstaterats i Sverige. Ett alternativ byggsätt för den putsade fasaden är att putsa mot ett skivunderlag som sitter monterat mot läkt så att en luftspalt bildas. Om spalten i över- och underkant kan kommunicera med utomhusluften så kommer vind och temperaturskillnad

Language, Nuclear Waste and Society : The Preservation of Knowledge over Vast Periods of Time and its Relevance for Linguistics

The article discusses the impact of comparative/historical philology upon the question of nuclear semiotics, i.e. the field of how humanity is to communicate information about nuclear waste storage into the distant future and its (presumably human) inhabitants. It also turns this perspective on its head and discusses possible insights in the other direction – what Nuclear Semiotics can teach histo
