Various aspects of the strong interaction are considered. Correlation effects in the hadronization process in a string model are studied. A discrete approximation scheme to the perturbative QCD cascade in e+ e- annihilation is formulated. The model, Discrete QCD, predicts a rather low phase space density of "effectlve gluons". This is related to the properties of the runnin
Popular Abstract in Swedish Råttans urinblåsa har studerats ur olika aspekter, sedan antingen ett standardiserat avflödeshinder åstadkommits eller hälften av urinblåsans nervförsörjning avlägsnats. Avflödeshindret har åstadkommits genom att en silkestråd knutits runtom urinröret så att det försnävats. Genom att en knappt mm-vid metallstav knutits om samtidigt och sedan avlägsnats, har graden av avMedian micturition volume decreased early after partial outlet obstruction, 24 hrs total obstruction and hemidenervation. Degeneration release of transmitter may explain this, assuming that bladder wall distension causes nerve degeneration. Micturition pressure decreased simultaneously in the partially denervated and 24 hrs obstructed groups, probably due to the reduced number of functionally inta
Popular Abstract in Swedish Fåglars flygförmåga I alla tider har vi fascinerats av fåglars förmåga att flyga, och många försök att förstå och efterlikna dem har gjorts. Kanske den förste som på allvar intresserade sig för mekanismerna bakom fåglars flykt var Leonardo da Vinci som runt år 1500 funderade på hur fåglar alstrar lyftkraft. Leonardo skissade också på 100-tals maskiner som var tänkta atI share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. Gliding flight performance of a jackdaw was measured in a wind tunnel and I conclude that the current model for predicting optimum wingspan as a function of forward gliding
It is generally agreed that children are able to acquire two languages to which they are exposed from birth as two L1s. Little attention has been drawn to cases when one language develops slower and is weaker in different aspects. A question under debate is whether the weaker language develops as an L2 rather than as an L1. The goal of this paper is to contribute to the understanding of the weaker
This paper deals with geographical and organisational patterns of knowledge flows in the media industry of southern Sweden, an industry that is characterised by a strong ‘symbolic’ knowledge base. Aim is to address the question of the local versus the non-local as the prime arena for knowledge exchange, and to examine the organisational patterns of knowledge sourcing with specific attention paid t
Alzheimer´s Disease (AD) is a progressive neurodegenerative dementia characterized by the extracellular accumulation of the beta-amyloid (Ab) peptide into plaques and intracellular phosphorylation and accumulation of tau protein into neurofibrillary tangles (NFT). Inflammation due to astrocytic and microglial activation is one of the ongoing processes in the disease giving rise to cytokine product
A brief introduction to convolutional coding is given. The active distances are reviewed and shown to be an important tool for analyzing the error correcting capability of maximum-likelihood (ML) decoding of convolutional codes when communicating over a binary symmetric channel (BSC). Due to memory and delay constraints in practical coding schemes, convolutional codes often are either terminated o
Combined quantum chemical and molecular mechanics geometry optimisations have been performed on myoglobin without or with O(2) or CO bound to the haem group. The results show that the distal histidine residue is protonated on the N(varepsilon2) atom and forms a hydrogen bond to the haem ligand both in the O(2) and the CO complexes. We have also re-refined the crystal structure of CO-myoglobin by a
The currant shoot borer, Lampronia capitella (Lep., Prodoxidae), is an important pest of currants, Ribes spp., in northern Europe. Oviposition was studied in cage experiments and the flight period was monitored in field studies using pheromone-baited traps. Blackcurrant, Ribes nigrum, was the host species in both studies. The total egg supply of females was on average 107 eggs and oviposition star
Sweden's decision to choose neutrality as its security policy orientation in the first half of the nineteenth century is explained with the help of image theory. It is argued that a theory focusing on the images of policy-makers regarding self, others and situation provides a better explanation of these strategic decisions than traditional balance-of-power theories. The important role of enemy-ima
Human liver alpha-L-fucosidase (alpha-L-fucoside fucohydrolase, EC 3.2.1.51) has been separated into four components by chromatography on Sephadex G-150 or DEAE-cellulose. These components differ in their relative stability to heat and acid treatment, and their response to neuraminidase. The serum enzyme was devoid of high molecular weight activity and probably contained more sialic acid residues
This article traces the reception of the the Swedish film Ingeborg Holm in 1913. The film created a fierce debate regarding the Swedish poor laws. This debate eventually led to changes in the law in 1918.
Childhood conduct disorder (CD) and adult psychopathic traits according to the Psychopathy Checklist Revised (PCL-R) were the closest psychiatric covariates to repeated violent crimes and aggression among offenders under forensic psychiatric investigation in Sweden. As psychopathy is not included in the present psychiatric diagnostic systems, we compared total and factor PCL-R scores to Axis I dis
