Popular Abstract in Swedish Störningar i händernas finmotorik, kraft och känsel är vanliga symtom efter långvarigt bruk av handhållna vibrerande verktyg. I gynnsamma och lindriga fall kan dessa besvär gå tillbaka efter upphörande av expositionen för vibrationer. I mer avancerade fall tilltar besvären och ett hand-arm vibration syndrom (HAVS) utvecklas. Detta tillstånd utgör ett av de allvarligare Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. The general purpose of this thesis was to test the hypothesis that vibration exposur

Governance is hybrid to the extent that it involves several types of stakeholders, jurisdictional domains, and organisational forms. This paper analyses governance of household solid waste management in Sweden from a hybridity perspective, with the City of Helsingborg as example. The empirical material on which the paper is based consists of interviews with politicians, civil servants and manageme

Popular Abstract in Swedish Tryptofan (TRP) är en s.k. essentiell aminosyra d.v.s. den kan inte syntetiseras av kroppen utan måste intas med födan. TRP ingår bl.a. som byggsten i kroppens proteiner men TRP används även som substrat för bildningen av signalsubstansen serotonin (även kallad 5-hydroxytryptamin; 5-HT). Dessutom kan TRP användas för bildningen av de för kroppen livsviktiga molekylerna In the present study, L-tryptophan (TRP)-related disturbances in the brain in experimental hepatic encephalopathy (HE) were investigated. The endogenous NMDA-receptor agonist and L-TRP metabolite quinolinic acid (QUIN) has been suggested to be involved in the pathogenesis of HE. We were, however, unable to detect any increases in QUIN levels in rats subjected to a chronic portacaval shunt (PCS) ei

Popular Abstract in Swedish De möjliga energinivåerna en elektron kan befinna sig i är olika för olika atomer och joner, en atom där en eller flera elektroner kastats ut. Detta kommer att medföra att det utsända ljuset, spektret, från en atom/jon kommer att vara unik för varje atom/jon, på samma sätt som vi människor har var sitt unikt fingeravtryck. Om man tittar upp på stjärnhimlen en klar vintNew measurements of the elements Ba, Fe, Ga, In and Ru are reported. The analysis of barium contains new wavelengths, improved energy level values and new values of the ionization limit in both Ba I and Ba II. Oscillator strengths and radiative lifetimes in Fe II, as a part of the FERRUM project, are reported. The gallium analysis includes new wavelengths, ab initio calculated oscillator st

In this study, we will analyse the acquisition of subject pronouns in French and the distribution of Null subjects in early stages of language acquisition. We will contrast bilingual first language acquisition (2L1) and adult second language acquisition (L2). In both cases, Swedish is present as one of the two languages of the bilingual children, and as source language for the L2 learners. We wil

As international competition increased towards the end of last century, companies realized the importance of collaborating and sharing information with suppliers and customers to remain competitive. By sharing information such as forecasts of future demand with partners in the supply chain, it was possible to lower inventory holding costs and increase the service level to customers, and thereby in

Social anxiety disorder (social phobia) is a debilitating and common anxiety disorder, with a lifetime prevalence ranging from 6 % to 12 %. The condition has its onset in childhood and early adolescence, affects females more often than males, and if untreated is associated with high risk of developing comorbid anxiety and mood disorders, as well as substance abuse. The increasingly growing body of

Popular Abstract in Swedish I denna avhandling undersöks vilka funktioner cytoskelettproteinet desmin har strukturellt och funktionellt i hjärta och skelettmuskel. Genom att studera funktionen i hjärt- och skelettmuskler i en transgen musmodell, Des-/- som helt saknar proteinet desmin (delarbete I-III), kan vi uppskatta hur viktigt desmin är för muskelkontraktionen. Vi har även studerat hur en mutWe have examined the functional and structural roles of the cytoskeletal protein desmin in cardiac and skeletal muscles using a genetically modified mouse (Des-/-) with the desmin gene ablated. Desmin forms filaments at the Z-disks in the striated muscle sarcomere, have connections to the sarcolemma and most likely align sarcomeres and whole cells. We have shown a decreased contractile function of

To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. Our experiments on seed germinat
