Traditionally, when process identification, monitoring and diagnostics are carried out for power plants and engines, physical modeling such as heat and mass balances, gas path analysis, etc. is utilized to keep track of the process. This type of modeling both requires and provides considerable knowledge of the process. However, if high accuracy of the model is required, this is achieved at the exp

Popular Abstract in Swedish Aneurysm är ett sjukdomstillstånd som är känt sedan ca 2000 år före vår tideräkning, och bukaortaaneurysm (bråck på stora kroppspulsådern i buken) beskrivs i publikationer från 1500-talet. På 1800-talet försökte man sig på att behandla med ligering, tyvärr med dåligt resultat, och först på 1920-talet beskrivs den första lyckade ligeringen. Behandling med graftrekonstrukThe incidence of abdominal aortic aneurysms (AAA) is increasing. The risk of rupture is related to diameter. However, rupture may occur also in small AAA. To evaluate the size of an aneurysm when related to the predicted normal aortic diameter might be a better predictor of risk. AAA:s, range 40-55 mm were studied in relation to gender. No difference in AAA diameter was found. However, body surfac

Delamination and spallation of thermal barrier coating (TBC) systems, used in hot parts of gas turbines, have been studied with respect to thermal fatigue. TBCs with and without pre-existing cracks were investigated. Thermal shock tests were performed until coating spallation. The experimental results revealed that the cracks primarily responsible for spallation grew horizontally, close to the int

Two enzymes involved in the biosynthesis of polyamines, ornithine decarboxylase (ODC, from human and Leishmania donovani) and spermidine synthase (SPDS, from Plasmodium falciparum and Caenorhabditis elegans) were studied using biochemical methods, homology modelling and X-ray crystallography. ODC catalyses the first and committed step in polyamine biosynthesis, the decarboxylation of ornithine to

Popular Abstract in Swedish I denna avhandling har jag studerat jordlöparnas (Carabidae) dynamik i de intensivt brukade landskapen som återfinns i Skånes slättbygd. Jordlöpare är en artrik familj av rovlevande skalbaggar som är vanligt förekommande i jordbruksmark. De livnär sig på en mängd olika insekter, andra leddjur och blötdjur, som t.ex. skadedjur såsom bladlöss eller kålflugans ägg. För attIn this thesis I have focused on studying dynamics of ground beetle assemblages in intensively managed agricultural landscapes. By definition, the land cover of these landscapes is dominated by annually tilled farmland, comprising a range of different crop types, in the context of the southern Swedish province of Scania mostly winter wheat, spring barley, winter rapeseed, and sugar beets. This bac

This work concerns an experimental study of pressure drop and heat transfer for turbulent flow inside a U-duct with relevance for tip cooling of gas turbine blades. The U-duct models the internal blade cooling flow passages. Both friction factors and convective heat transfer coefficients were measured along the bend (turn) part of the U-duct for three different rib configuration cases, namely (a)

This dissertation deals with the rental relations in Malmö between 1880 – 1925. This period witnessed extensive changes in Swedish society, including on the housing market. Industrialization and the rapid pace of urbanization created the basis for a housing market with a strong speculative element. Tenement housing made its breakthrough in Malmö around the turn of the 20th century. New housing are

The need for control of the influent load to a wastewater treatment plant (WWTP) is becoming more important. One reason for this is that there are a number of things that cannot be achieved with plant-focused control. For instance it is hard to avoid sludge loss as a result of poor settling or reducing a too high influent flow rate by in-plant control actions. It is also difficult to reduce the ef

In this thesis the evolution and consequences of multiple queen societies (polygyny) in leptothoracine ants are discussed. The majority of the studies have been conducted on the boreal species Leptothorax acervorum, but polygynous behaviour is also discussed in a broader sense concerning ant species in general. In L. acervorum the intra-colony relatedness is high. Relatedness in monogynous colonie

Popular Abstract in Swedish Blågröna alger (cyanobakterier) av släktet Arthrospira förekommer i salthaltiga, alkaliska, tropiska vatten i Afrika, Asien och Centralamerika. Kanembu stammen vid Chadsjön och aztekerna i Mexiko har av tradition använt Arthrospira i matlagningen som ett näringskomplement. Under senare år har släktet Arthrospira uppmärksammats vetenskapligt och kommersiellt. Nu odlas Ar

The European project Nature-SDIplus has developed data and metadata specifications for three INSPIRE Annex III themes: Habitat and Biotopes, Bio-geographical regions and Species distributions. These serves as a foundation for the thematic groups developing the corresponding INSPIRE specifications. The aim of this study is to test a data harmonization approach to make Swedish environmental geodata

Popular Abstract in SwedishDenna studie utgår från tanken att ett samhälle kan ses som en grupp individer förenade i ett nätverk av sociala relationer. Nyckeln till förståelsen av samhället ligger därför i studiet av dessa sociala nätverk som den praktik (mikronivå) vari de sociala strukturerna (makronivån) reproduceras och förändras.Syftet med studien är att utifrån de sociala nätverken studera hThe aim of the study is to examine, using the social networks as a starting-point, the way a local community is constructed in a specific historical context, namely the industrial community of Limhamn in southern Sweden at the time of the Industrial Revolution 1870-1914. In 1870 the Skånska Cement Company initiated a large-scale extraction of limestone in the area and soon had cement works built i

Popular Abstract in Swedish En stor del, kanske den största delen, av den information som vi dagligen får om världen tillhandahålls genom ett av våra fem sinnen: synen, med vilken ögat registrerar det ljus som vi omges av. Det ljus som vi kan registrera och uppfatta som färger är egentligen bara en bråkdel av den elektromagnetiska strålning som universum är uppfyllt av: Det finns även röntgenstrålThis thesis intends to provide spectroscopic information which may be of use in the investigation of low-density plasmas. Developed since the 19th century, the spectroscopic approach has proven to be a versatile method for measuring properties in hot gases, such as electron and ion temperatures and densities, the abundance of various elements in the gas, etc. However, such investigations rely on k

Popular Abstract in Swedish Prosodi definieras som talets rytmiska, dynamiska och melodiska egenskaper (Bruce, 1998). Till de prosodiska dragen hör längd (kvantitet), betoning (tryck- och ordaccent), ton, satsmelodi (intonation) och gränser (tomrum i talvågen). Dessa drag används i kommunikativt syfte för att särskilja betydelser hos ord och orddelar, för att framhäva och gruppera delar av talet oThe aim of this thesis was to explore prosodic problems in Swedish children with language impairment (LI). In the first study, 29 children with LI participated. They were assessed with an assessment procedure for prosody at the word, phrase and discourse levels, developed within this thesis. The results showed that 41% of the children had prosodic problems to some extent. In addition, reliability

The Convention on the Rights of Persons with Disabilities (CRPD), adopted by the UN in 2006, represents the coming of age of a human rights approach to disability. In doing so, it provides answers to the questions what ‘disability’ is, who ‘persons with disabilities’ are and what entitlements are legitimate and relevant in relation to ‘disability’. Partly, these answers flow from the heritage of i
