Pentecostalism and the Other : Seclusion, Engagement and Spiritual Warfare

This article deals with the Pentecostal Christianity and the relation to the other by looking at theological and practical responses on how Pentecostals deal with the world that generally is seen to be infused by evil. By first looking into some broad theological themes on how negotiate the social world in which Pentecostals reside, the theological base will be discussed against empirical material

Dikter i Grönköpings Veckoblad : Av Gunnar Ekelöf, utgivna med en inledning och kommentarer av Daniel Möller

Gunnar Ekelöf var en återkommande medarbetare i Grönköpings Veckoblad under slutet av 1940-talet och det tidiga 1950-talet. I sina alster i tidningen – flertalet publicerade under signaturen A:lfr-d V:stl-nd – ger han uttryck åt en hittills okänd sida av författarskapet. I inledningen diskuterar Daniel Möller, bokens redaktör, Ekelöfs motiv och avsikter med sina bidrag i veckobladet. Möller uppmär

Epidemiology of intra- and peri-articular structural injuries in traumatic knee joint hemarthrosis – data from 1145 consecutive knees with subacute MRI

Objective In patients with traumatic knee distorsion and hemarthrosis, to investigate the panorama of structural injury, as visualized on magnetic resonance imaging (MRI). Design Cohort study of 1145 consecutive patients with traumatic knee distorsion who underwent MRI within median 8 days after injury. We present structural injury as visualized on MRI in relation to age, sex and activity at injur

Review of current study methods for VRU safety. Part 1 – Main report

The report presents the results of a review of the study methods related to vulnerable road user safety that are used today and aims to link accident causation factors to VRU accident risk. The review covered the following categories of study methods: epidemiological studies based on accident and injury data; in-depth accident investigations; naturalistic driving studies; behavioural observations;The report presents the results of a review of the study methods related to vulnerable road user safety that are used today and aims to link accident causation factors to VRU accident risk.

Institutional conditions for integrated mobility services (IMS) : Towards a framework for analysis

The present text is a theoretical framework that has been developed with the aim to generate knowledge of and policy recommendations for the promotion of integrated mobility services (IMS), with specific regard to institutional dimensions. Integrated mobility services are services where the passenger’s transport needs are met by a service that not only integrates a range of mobility services, both

Late Cycle Soot Oxidation in Diesel Engines

Diesel engines are the most common engine technology used in transportation. Its widespread use comes from its inherent high efficiency and its relative low cost. It suffers from pollutant emission issues, however, that need detailed understanding of their origins to meet the strictest current and upcoming emission standards. The work presented in this thesis focuses on the study of the mechanism

Parameters Influencing Soot Oxidation Rates in an Optical Diesel Engine

Soot emissions from diesel engines are the net result of two competing processes: soot formation and soot oxidation. Previous studies have shown poor correlation between soot formation rates and the soot emissions. This article presents a systematic study of a number of parameters affecting soot oxidation rate and how it correlates with the soot emissions. An optical heavy-duty engine is used in c

Comparison of Laser-Extinction and Natural Luminosity Measurements for Soot Probing in Diesel Optical Engines

Soot emissions from diesel internal combustion engines are strictly regulated nowadays. Laser extinction measurement (LEM) and natural luminosity (NL) of sooty flames are commonly applied to study soot. LEM measures soot along the laser beam path and it can probe soot regardless of temperature. NL integrates the whole field of view and relies on soot temperature. In this work, a comparison of simu

A Study of In-Cylinder Soot Oxidation by Laser Extinction Measurements During an EGR-Sweep in an Optical Diesel Engine

Two competing in-cylinder processes, soot formation and soot oxidation, govern soot emissions from diesel engines. Previous studies have shown a lack of correlation between the soot formation rate and soot emissions. The current experiment focuses on the correlation between soot oxidation rates and soot emissions. Laser extinction is measured using a red (690nm) laser beam, which is sent verticall

Investigation of Late-Cycle Soot Oxidation Using Laser Extinction and In-Cylinder Gas Sampling at Varying Inlet Oxygen Concentrations in Diesel Engines

This study focuses on the relative importance of O2 and OH as oxidizers of soot during the late cycle in diesel engines, where the soot oxidation is characterized in an optically accessible engine using laser extinction measurements. These are combined with in cylinder gas sampling data from a single cylinder engine fitted with a fast gas sampling valve. Both measurements confirm that the in-cylin

Quality Registries in Sweden, Healthcare Improvements and Elderly Persons with Cognitive Impairments

Policy-makers, the medical industry and researchers are demonstrating a keen interest in the potential of large registries of patient data, both nationally and internationally. The registries offer promising ways to measure and develop operational quality within health and medical care services. As a result of certain favourable patient data regula- tions and government funding, the development of

Neurons against Noise : Neural adaptations for dim light vision in hawkmoths

Alla djur uppfattar världen med sina sinnen, vilka ger information till beslut och rörelser. Tyvärr har sinnena begränsningar och när de upphör att ge pålitlig information kommer djurets överlevnad att hotas. Synsinnet till exempel utmanas dagligen, eftersom dess signalstyrka minskar när mörkret faller och ökar igen när solen går upp. I denna avhandling undersökte jag synsystemets anpassningar hosAll animals perceive the world through their senses, which form the basis for their decisions and motor actions. However, when these all-important senses reach their limit and cease to provide reliable information, the animal’s survival is threatened. Among the senses, vision is brought to its limits on a daily basis, because its signal strength is diminished as night falls, and increases again as

N-acetylation of arylalkylmines (serotonin and tryptamine) in the crayfish brain.

1. The presence of N-acetyltransferase in the crayfish brain (Pacifastacus leniusculus) was investigated. The arylalkylamines tryptamine and 14C-serotonin, are acetylated by crayfish brain homogenates with the acetyl donors 3H-acetyl coenzyme A and N, S-diacetylcysteamine, respectively.2. Resolution of serotonin metabolites by thin layer chromatography (chloroform/methanol/glacial acetic acid, 93

Identification of L-3,4-dihydroxyphenylalanine in the brain of the crayfish Pacifastacus leniusculus (Dana) and in tentacles of the sea anemone Metridium senile (L) by use of gas chromatography-mass spectrometry.

1. The amino acid l-3,4-dihydroxyphenylalanine (l-DOPA) was extracted from tentacles of the sea anemone Metridium senile and from brains of the crayfish Pacifastacus leniuscuius.2. The identity of l-DOPA was ascertained by gas chromatography-mass spectrometry as the heptafluorobutyryl iso-butyl ester derivative. Dopa is identified with GC-MS for the first time and the derivatization is a novel mod
