A gas chromatography-negative ion chemical ionization-selected ion monitoring-mass spectrometry (GC-NICI-SIM-MS) method was used to quantitate the metabolite toluene diamine (TDA) in urine samples of toluene diisocyanate (TDI) exposed workers. In order to validate the biological monitoring method, air samples were collected and analyzed using a liquid chromatography tandem mass spectrometry (LC-MS

Städer i sin snävaste betydelse är ett sentida fenomen. Eftersom de vuxit fram under en process är de inte så entydigt definierade som vi i nutiden antar. Problemet blir tydligt när vi tvingas omnämna orter som ”proto-urbana” eller använda begrepp som ”centralplatser”. Dessa begrepp antyder att livsmönstret inte riktigt utvecklats till en ”riktig” stad eller att det embryonala urbana livsmönstret

Popular Abstract in Swedish Vid framställning av koncentrerade fruktjuicer utsätts produkten för värmebehandling i form av indunstning och pastörisering. Värme-behandlingen försämrar produktens sensoriska kvalitet, dels eftersom aromerna är flyktiga och snabbt avdunstar, och dels eftersom värmen påskyndar kemiska förändringar av aromämnena. Några viktiga fördelar uppnås dock genom tillverkning av During production of concentrated fruit juices, both physical and chemical losses of aroma compounds occur due to heat treatment such as pasteurisation and evaporation. This leads to an inferior quality of the final product. By recovering the aroma complex from fresh juice and then adding it back to the processed juice, heat treatment can be avoided. Hydrophobic pervaporation is an emerging membr

This paper presents the implementation of the mapper block in a faster-than-Nyquist (FTN) signaling transmitter. The architecture is Look-Up Table (LUT) based and the complexity is reduced to a few adders and a buffer to store intermediate results. Two flavors of the architecture has been designed and evaluated in this article, one, a register based implementation for the buffer and the other usin

This paper explores the bearing had by Aymara notions of spirit loss on contemporary indigenous discourses of colonialism and decolonization and discusses the dynamics of cross-fertilization between “traditional” curing practices and cosmology on the one hand and indigenous ethnopolitical activism and discourse on the other.

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Parkinson's sjukdom är näst efter Alzheimer's sjukdom den vanligast förekommande neurologiska sjukdomen. Parkinson's är en förhållandevi's vanlig neurologisk sjukdom och det finn's belägg för den i alla kulturer där sjukdomsstatistik för's. I Sverige lever idag cirka 20 000 personer med sjukdomen. Förekomsten av sjukdomen är starkt åAbstract Aims: The aim of this thesis was to investigate how the impact of Parkinson’s disease, a chronic neurodegenerative disorder, influences the person’s health-related quality of life. The aim was also to investigate nursing assessment and management of Parkinson’s in elderly persons. Methods: The study started in1998, one year later a follow-up was conducted. The sample contained in the fir

This paper investigates to what extent and how the sociological perspective of Erving Goffman is represented in Swedish sociology-textbooks and why it is represented the way it is. The investigation has been restricted to central Swedish textbooks during the period 1970-2000 and consequently it does not give a complete picture, but since the choice of textbooks reflects central currents and person
