To tell or not to tell? Youth's responses to unwanted Internet experiences

This study is one of the first that investigated youth’s response to unwanted Internet experiences, not only for those youth who were bothered or distressed but for all youth who reported the experience. Three types of response were examined: telling someone about the incident and ending the unwanted situation by active or passive coping. Responses to the following unwanted Internet experiences we

Tightly Coupled Positioning and Multipath Radio Channel Tracking

Radio based localization is an active research topic with a wide range of applications. In this paper, we focus on localization of a radio receiver equipped with an inertial measurement unit. The localization is performed while simultaneously constructing a map of the small scale fading pattern in the local radio environment. The map in our case is a ray-trace-based multipath channel model. This s

Prevalence of dementia subtypes: A 30-year retrospective survey of neuropathological reports.

We investigated the distribution of neuropathologically defined dementia subtypes among individuals with dementia disorder. The neuropathological reports were studied on all patients (n=524; 55.3% females; median age 80, range 39-102 years) with clinically diagnosed dementia disorder who underwent complete autopsy including neuropathological examination within the Department of Pathology at the Un

Permutational Grammar for free word order languages

Permutational Grammar, PG, is a grammar inspired by the Free Word Order grammar, FOG, presented in Vladimir Pericliev & Alexander Grigorov 1992. Some languages, notably Latin, are said to have free word order, see e.g. Siewierska 1988. The name Permutational Grammar is derived from the use of permutations in order to generate order variation. The general problem to be solved by FOG and PG is t

“The green political consumer of food: A critical analysis of the research and policies”

Abstract in UndeterminedThis paper reviews the current literature on political and ethical consumers, and relates it to the topic of sustainable food consumption. A first aim is to problematise a somewhat simplistic view of the political and ethical consumer found in the literature. The paper sheds light on some of the dilemmas that confront green political consumers. We indicate that most existin

Weak A phenotypes associated with novel ABO alleles carrying the A(2)-related 1061C deletion and various missense substitutions.

BACKGROUND: The 1061delC single-nucleotide polymorphism (SNP) has been reported mostly in the context of the common A(2)[A201] allele and typically produces an A(2) phenotype. This study evaluated new A(weak) alleles, each containing 1061delC. STUDY DESIGN AND METHODS: Twenty samples were referred to our laboratory for analysis due to suspected A(weak) phenotypes originally detected at the referri

Fondaparinux or enoxaparin: A comparative study of postoperative bleeding in coronary artery bypass grafting surgery.

Objectives. Preoperative treatment with anti-coagulants for patients with non-ST-elevation acute coronary syndromes (NSTE-ACS) exposes patients undergoing surgical revascularization to a higher risk of perioperative bleeding. The aim of this study was to compare the effect on bleeding and transfusion needs during cardiac surgery for patients treated with enoxaparin or fondaparinux. Design. Using a

Wallenbergs fysikpris: Pröva själv en av teoriuppgifterna

I oktober 2012 lanserades ”Projekt Helix” på Liseberg – en ny stor berg- och dalbana inför vårpremiären 2014. Den klassiska Lisebergbanan får nu sällskap på berget av en något längre bana, med många nya element och exempel på ny teknik. Bland annat innehåller den två accelerationszo- ner, där tåget tillförs energi med linjära synkronmotorer (LSM). Efter den andra accelerationszonen, där tåget får

Trummor av keramik?

Trummor där trumkroppen är tillverkad av keramik är kända från etnografiska sammanhang bl a från Afrika. Flera av dessa trummor har använts vid speciella ceremonier från exempelvis Lesotho finns en trumma som sägs användas vid flickornas initierings riter och i Benin används en typ av trumma vid begravning. Från Europeisk förhistoria finns tämligen säkra fynd av keramiktrummor från Yngre Stenålder

Robotic Friction Stir Welding for Flexible Production

Popular Abstract in Swedish Friction Stir Welding eller ”friktionsomrörningssvetsning” är en svetsprocess som kräver ett roterande verktyg som genom friktionsvärme får materialet att mjukna. Verktyget blandar runt det plastiska materialet mekaniskt och skapar en fog av hög kvalité. Processen fungerar utan gas, utan rök, utan tillsatsmaterial och utan att smälta materialet. Alla dessa fördelar skapFriction Stir Welding (FSW) is a modern welding process that joins materials by frictional heat, generated by a rotating tool. Unlike other welding processes, the material never melts, which is beneficial for the weld properties. FSW is already widely adopted in several industries but the applications are limited to simple geometries like straight lines or circular welds, mostly in aluminium. The
