The objective of this work was to design and evaluate an experimental setup to be used for field studies of particle formation in biomass gasification processes. The setup includes a high-temperature dilution probe and a denuder to separate solid particles from condensable volatile material. The efficiency of the setup to remove volatile material from the sampled stream and the influence from cond

Popular Abstract in Swedish Då en struktur utsätts för varierande belastning kan brott uppstå vid väsentligt lägre last än vad som hade orsakat brott vid konstant lastnivå. Fenomenet kallas utmattning och berör många traditionella ämnen. För att kunna göra relevanta bedömningar av livslängden vid utmattningsbelastning krävs kunskap om materialets egenskaper, både mikroskopiskt och makroskopiskt, t

Why is waste such an important topic for understanding the management of overflow? First, because waste is a classic symbol of overflow: to be flooded with too much stuff that demands handling, sorting, and decision-making is a feeling well known in consumer society. Facts and figures speak of the same overflow. Waste disposal is a growing problem. The downside of consumption is a growing mountain

With the exponential growth of the World Wide Web, automated subject classification of Web pages has become a major research issue in information and computer sciences. Organizing Web pages into a hierarchical structure for subject browsing is gaining more recognition as an important tool in information-seeking processes. In this thesis, different automated classification approaches, focusing on

This study explores the emergence of the Christian biblical canon and its significance for the early as well as for the contemporary church. Some major challenges to previous research on the biblical canon are presented. The apostolic formula "the Scriptures and the Lord" is defended as a good summary of the Christian canon, its formation and significance. It is argued that the canon was formed i

Popular Abstract in Swedish Socialakrobat, världsförbättrare, soc-kärring. Benämningarna på socialarbetare har skiftat genom åren, liksom synen på yrket. I Fattigdomens besvärjelser skildras den svenska fattigvårdens förvandling till modern socialvård. Det är arbetets vardag som står i fokus, många gånger i kontrast till socialarbetarnas visionära förhoppningar. Vi får möta sekelskiftets filantroThe theme of this dissertation is how changing claims as to what is proper and true social work have been formulated and staged in the twentieth century. From the perspective of cultural analysis I seek to discuss how social work has been formed and changed over a century. I wish to demonstrate how descriptions and narratives, actions and gazes, practice and rhetoric have constituted a changing pr

Proteins are composed of 20 different amino acids. In the translation process, each of these 20 amino acids is specifically recognized by their cognate aminoacyl-tRNA synthetase. The fidelity of this recognition system is essential if translation is to function properly. The development of an in vitro system based on this recognition scheme would make a powerful analytical tool with which to analy

Lund University, Sweden, is the only seat of learning having Sociology of Law (hereafter SoL) at all levels in Europe. SoL was initiated in 1972 as a department at the Social Science Faculty, with professor Per Stjernquist as chair. Later on, for some 10 years, SoL was a division within the department of Sociology but from January 2006, SoL is an autonomous department at the Social Science Faculty

Context. The ESA space astrometry mission Gaia, planned to be launched in 2013, has been designed to make angular measurements on a global scale with micro-arcsecond accuracy. A key component of the data processing for Gaia is the astrometric core solution, which must implement an efficient and accurate numerical algorithm to solve the resulting, extremely large least-squares problem. The Astromet

Background Leaf-cutting ants live in symbiosis with a fungus that they rear for food by providing it with live plant material. Until recently the fungus' main inferred function was to make otherwise inaccessible cell wall degradation products available to the ants, but new studies have shed doubt on this idea. To provide evidence for the cell wall degrading capacity of the attine ant symbiont, we

The aim of this thesis is to analyse how members of the Swedish press were represented in different media from the 1870s to the 1930s, how and why the representations were changed, and the way newspaper staff responded to them. The representations of journalists in novels, short stories, movies, press history, press debates, pictures in the funny papers and so on are analyzed as parts of the publi

There has been a significant interest in the estimation of time and effort in fixing defects among both software practitioners and researchers over the past two decades. However, most of the focus has been on prediction of time and effort in resolving bugs, without much regard to predicting time needed to complete high-level requirements, a critical step in release planning. In this paper, we desc

The Drosophila antenna contains receptor neurons for mechanical, olfactory, thermal, and humidity stimuli. Neurons expressing the ionotropic receptor IR40a have been implicated in the selection of an appropriate humidity range [], but although previous work indicates that insect hygroreceptors may be made up by a "triad" of neurons (with a dry-, a cold-, and a humid-air-responding cell []), IR40a

The present thesis investigated how listeners use prosody to rapidly predict upcoming lexical and syntactic structures. In the first three studies, it was shown that listeners take advantage of Swedish word-level tones to pre- activate upcoming word endings. Every Swedish word has a tone on the word stem – known as a ‘word accent’ – which is either low or high, and the tone is assigned to the stem

Contemporary debates on sustainability usually relies on standardised and normative categories, such as ‘social’ and ‘nature’, and on linear notions of time. This study explores a more complex perspective on the delicate borderlands between the ‘un-sustainable’ and the ‘sustainable’. A particular material and a particular place stand at the centre of attention: woollen Merino fibre on the South Am

Energy-intensive processing industries like the concrete industry form the base of the economy and account for a large part of global greenhouse gas emissions. Sectoral transformation to cleaner basic materials is therefore crucial, and institutional pressure to do so is increasing. However, socio-technical studies have not sufficiently addressed these sectors. This paper therefore sets out to ana

During the past decades, the Swedish welfare state has been transformed in profound ways. Many important changes are related to the labour market, particularly the organisation of the unemployed. The unemployment insurance, as well as the health insurance system has changed dramatically, resulting in implications for the organisation of work at the Swedish National Employment Agency, Arbetsförmedl

This study is an analysis of norm critical pedagogy has been used in a pedagogic activity outside the formal, institutionalized education. The aim was to analyze how the implementation of norm critical pedagogy can be done and what effects it may have on those who participate in the educational activities. For four months, I followed the project Uppdrag Ninjas who are working with democracy, equal

Skatterättens område är dynamiskt. Företag och privatpersoner har i olika omfattning möjlighet att planera sin verksamhet. Det finns ett kontinuerligt intresse av att finns nya vägar som resulterar i en förmånligare skattemässig situation. Dessa nya förfaranden med vad som kan te sig röra procentenheter kan i slutändan resultera i enorma ekonomiska vinster. Under 2003 tillkom nya regler om skattTax law is a dynamic field. Businesses and individuals are to a different extent able to plan their activities. There is a continuous interest to find new ways that result in more favorable tax situations. These new procedures with what may seem to concern percentile margins may ultimately result in huge economic gains. In 2003 a new legislation was introduced regarding tax exemption on business-

Vägen från bären på kaffeträdet, vars frön är det vi kallar kaffebönor, till en färdig kopp kaffe består av flera steg. Det viktigaste steget för den slutliga produkten är rostningen,och här uppstår oundvikligen en signifikant förlust av massa. Kan det vara så att denna förlust påverkas av råkaffets egenskaper?Coffee is one of the world’s largest trading goods and produced in a large number of countriesall over the world. The largest producers are from South America, Asia, Central America and Africa, and Brazil, Vietnam, Colombia and Indonesia are in order the largest producers,together producing more than the half of the world supply. During roasting of coffee the weight of the production batch decrea
