This report is an evaluation of human safety and evacuation possibilities in case of a fire at Bräcke ice hockey arena, Sweden. Three fire scenarios have been analyzed and the modeling of these has been done by computer simulations and hand calculations. The time until the fire has reached critical conditions in the building was then compared with the time it takes for all the persons in the build

Populärvetenskaplig sammanfattning: De senaste åren har försurningsforskningen varit intensiv, men intresset har främst varit inriktat på det atmosfäriska nedfallets miljöpåverkan. Dock påverkas markmiljön även av markanvändningsformen och dess intensitet. Inom skogsbruket har det sedan länge varit känt att gran påverkar markens pH-värde negativt jämfört med björk. Det är mera sparsamt med jämföraChemical and mineralogical studies of forest soils were made in four Norway Spruce (Picea abies (L.) Karst) and broadleaf stands in Asa in southern Sweden. The aim of the study was to investigate the differences in soil forming processes between stands of coniferous (spruce) and broad-leaved trees. The investigation did not show any differences in soil acidity, which was measured by pHH2O, pHKCl,

According to statistics two thirds of Swedish criminals relapse into crimes within three years (Brå, 2007). Researchers suggest a relationship between attitudes toward crime and delinquent behaviour (Andrews & Bonta, 2003), but whether these attitudes are implicit or explicit remains unclear. Therefore, the aim of this study was to measure both constructs. Using SC-IAT (Karpinski & Steinma

Antalet subventionerade jobb har växt samtidigt som andelen utrikes födda bidragsanställda ökat och andelen funktionsnedsatta minskat. Anställningsbidragen är särskilt frekventa i handels-, restaurang-, städ- och bemanningsbranscherna. I föreliggande studie har samtliga nya anställningsbidrag 2016 i de fyra branscherna i Helsingborg undersökts. En tydlig etnisk segmentering påvisas genom att en be

This article explores the proposition that a reason for high agricultural productivity in the early nineteenth century was relatively high energy availability from draught animals. The article is based on the collection of extensive new data indicating different trends in draught power availability and the efficiency of its use in different countries of Europe. This article shows that the proposit

We report on magnetotransport measurements of nanoconstricted (Ga,Mn)As devices showing very large resistance changes that can be controlled by both an electric and a magnetic field. Based on the bias voltage and temperature dependent measurements down to the millikelvin range we compare the models currently used to describe transport through (Ga,Mn)As nanoconstrictions. We provide an explanation

Photosynthesis is the process by which energy of light is converted into chemical energy by plants, algae and photosynthetic bacteria. For this, highly specialized pigment-proteins have evolved that capture the light and transform the short-lived excited states of pigment molecules into a stable transmembrane potential. By close scrutiny of organization and processes of the photosynthetic pigment

The recent increase in R&D offshoring has raised fears that knowledge and competitiveness in advanced countries may be at risk of 'hollowing out'. At the same time, economic research has stressed that this process is also likely to allow some reverse technology transfer and foster growth at home. This paper addresses this issue by investigating the extent to which R&D offshoring is associa

The credit is a financial service which holds a vital role to the transactions between the financial and non-financial enterprises with their customers. The goal of credit is to aid the legal and physical persons to successfully face and thus to overcome their difficult economical situations. Due to the fact that the VAT exemption status of granting, negotiation and management of credit causes neg
