Popular Abstract in Swedish Det är ofta fördelaktigt att i olika sammanhang representera våra observationer av verkligheten med en följd av tal. Så skilda exempel som ljud, bilder, hjärnvågor, havsvattenvågor, jordbävningar och aktiekurser kan låta sig beskrivas av följder av tal. Man kan med fördel föreställa sig följden som en uppritad graf, där den horisontella axeln beskriver tidpunkten för mäThe theory of stochastic time-frequency analysis of non-stationary random processes has mostly been developed for processes in continuous time. In practice however, random processes are observed, processed, and interpreted at a finite set of time points. For processes in continuous time, the ambiguity domain has interesting properties which makes it particularly useful. One such property is that t

Vectoring is a vital component of wideband wire- line communication systems. A disorderly leaving event (DLE) disturbs the vectoring operation since the precoder, which was designed for the channel before the change, is no longer up to date. Measurements indicate that the impact of a DLE can be serious for frequencies beyond 30 MHz, which corresponds to the band used by emerging wideband communica

An evacuation experiment was performed in a road tunnel in order to investigate how motorists behave and emotionally respond when exposed to a fire emergency, how information and wayfinding systems are perceived and whether green flashing lights can influence exit choice. The participants believed that they were taking part in a study about driving behaviour. Approximately I kill inside the tunnel

In this work, three different methods were used to determine the phase behavior of alkyl ketene dimer (AKD) in supercritical carbon dioxide (SC-CO2). Rough values for the total solubility of AKD in SC-CO2 were obtained. The solubility ranges from 1 to 14 mg AKD/g CO2 at temperatures from 40 to 80 degrees C and pressures from 10 to 30 MPa. A significant increase in solubility was observed in the re

Abstract Background: Empowerment is essential in the rehabilitation process for people with psychiatric disabilities and knowledge about factors that may play a key role within this process would be valuable for further development of the day centre services. Objective: The present study investigates day centre attendees' perceptions of empowerment. The aim was to investigate which factors show th

The reaction kinetics of Candida antarctica lipase B (CalB) in the commercially available preparation Novozym (R) 435 (N435) were compared to those of preparations of CalB immobilised on Accurel (R) MP1000 (porous polypropylene). Two polypropylene preparations were made using enzyme loadings of 0.2% and 2% (w/w). All three preparations were used in hydrolysis as well as transesterification of two

The metabolic syndrome (MetS), characterized by obesity, hyperlipidemia, hypertension, and insulin resistance, is a growing epidemic worldwide, requiring new prevention strategies and therapeutics. The concept of prebiotics refers to selective stimulation of growth and/or activity(ies) of one or a limited number of microbial genus(era)/species in the gut microbiota that confer(s) health benefits t

The two major forms of the amyloid-beta (Aβ) peptide found in plaques in patients suffering from Alzheimer's disease, Aβ40 and Aβ42, only differ by two amino acids in the C-terminal region, yet they display markedly different aggregation behavior. The origins of these differences have remained challenging to connect to specific molecular-level processes underlying the aggregation reaction. In this

A search is presented for the production of new heavy quarks that decay to a Z boson and a third-generation Standard Model quark. In the case of a new charge +2/3 quark (T), the decay targeted is T -> Zt, while the decay targeted for a new charge -1/3 quark (B) is B -> Zb. The search is performed with a dataset corresponding to 20.3 fb(-1) of p p collisions at root s = 8TeV recorded in 2012 with t

Background: Patch testing has been used for more than 100 years as the best means to diagnose contact allergy. The increased use of the technique makes standardization of the methodology most important. Progress in the standardization of the patch test technique has been made through guidelines. Objectives: To investigate the intra-individual and inter-individual differences in reading of patch

This paper explores the attitude-behaviour gap from an identity perspective in order to better understand why tourists act sustainably at "home" but not when "away". The majority of tourism-related CO2 emissions stems from transport. Behavioural change is a possible way to reduce those emissions. However, research indicates that instigating behavioural change within tourism is problematic, because

Popular Abstract in Swedish Denna avhandling beskriver hur fluorescens kan användas inom biomedicinområdet. Fluorescens är ett fenomen, som uppstår när molekyler absorberar inkommande ljus och sedan återutsänder ljus som har längre våglängd än det inkommande ljuset, och därför lägre energi, då en del av det absorberade ljuset omvandlats till värme i det omkringliggande mediet. I mänsklig vävnad fiThe main theme of this thesis is the use of fluorescence spectroscopy in biomedicine. The work presented in the thesis can be divided into three areas of applications. The first area involves the use of fluorescence to find the location of a deeply situated fluorophore within turbid media. Fluorescence emitted from the fluorophore will be attenuated when propagating through the medium, due to the

[1] Vigorous debate still surrounds the cloud electrification process and unexplained regional variations in lightning activity. Here, we show that climatological maxima in lightning activity are associated with small effective diameter D-e of ice crystals near cumulonimbus cloud tops. This relationship, unlike lightning's more well-known relationship with cloud top height, is consistent over land

Popular Abstract in Swedish Studien behandlar bibelbruket i den grekiska systematiska samlingen av Apophthegmata Patrum ( kenfädernas tänkespråk). Efter en inledande genomgång av tidigare forskning på biblebruk i allmänhet och det i tänkespråken i synnerhet formuleras undersökningens syfte så: att beskriva hur bibeltexten kontextualiseras, dvs. hur texten infogas i den undervisning och de ideal soThis study is devoted to the use of the Bible in the Greek systematic collection of Apophthegmata Patrum (AP). After an introductory survey of earlier research on the use of Scripture in general, and that of AP in particular, the main purpose of the investigation is formulated: to describe how the Bible text is contextualized, i.e., how the text is integrated with the teachings and ideals in the s

Emotions at War: Sensibility and emotional strategies among Swedish officers, 1788-1814 This thesis studies the relationship between the emotional sufferings of Swedish officers in wartime during the period 1788-1814 and the various mental strategies they employed in order to deal with those sufferings. The study is positioned within the field of research commonly refered to as the history of em

Popular Abstract in Swedish Denna avhandling behandlar frågor om normbildning och argument för gemenskap i den svenska statsmaktens officiella retorik från 1660-1919. Varje nytt år skulle befolkningen i Sverige lyssna till de böndagsplakat som lästes upp i rikets kyrkor. Där informerades om riksdagar och gavs förklaringar till krig och kriser. Där beskrevs även grunden för rikets gemenskap och SveThis study deals with questions about norm building and arguments for community in official royal rhetoric in the Swedish realm from 1660 to 1919. Every year, an intercession day proclamation issued by the King in Council (Kungl. Maj:ts böndagsplakat) was read out from pulpits across Sweden. Like many communiqués, they belonged to the proclamation system, which included the spreading of informatio

Popular Abstract in Swedish Streptococcus pyogenes Människan är ständigt koloniserad av en mängd olika mikroorganismer. De flesta bakterier är ofarliga och en del av dem är faktiskt nödvändiga för oss, t.ex. de tarmbakterier som hjälper oss att producera vitaminer. Grupp A streptokocker (GAS) eller Streptococcus pyogenes, är en av de vanligaste sjukdomsframkallande bakterierna hos människan. De kaWe have found that a set of group A streptococcal strains, primarily associated with skin infections, express surface-associated M proteins that bind plasminogen and plasmin with high affinity. The binding is mediated by a common 13 amino acid internal repeated sequence located in the NH2-terminal surface-exposed portion of these M proteins. It could be demonstrated that plasminogen, absorbed by t

CYLD is a deubiquitination enzyme that regulates different cellular processes, such as cell proliferation and cell survival. Mutation and loss of heterozygosity of the CYLD gene causes development of cylindromatosis, a benign tumour originating from the skin. Our study shows that CYLD expression is dramatically downregulated in basal cell carcinoma (BCC), the most common cancer in humans. Reduced

Malignant hyperthermia susceptibility is diagnosed using an in vitro contracture test (IVCT). In families in which the mutation is known, genetic tests are also available. The inheritance pattern is regarded as autosomal dominant, which predicts equal proportions of men and women affected. The aim of this study was to investigate whether there were sex differences in the diagnostic outcome of the

Browning of inland waters has been noted over large parts of the Northern hemisphere and is a phenomenon with both ecological and societal consequences. The increase in water color is generally ascribed to increasing concentrations of dissolved organic matter of terrestrial origin. However, oftentimes the increase in water color is larger than that of organic matter, implying that changes in the c
