Popular Abstract in Swedish Stärkelse är en miljövänlig och naturlig produkt som kan framställas ur växtriket. Stärkelse har många användningsområden inom livsmedelsindustrin såsom förtjockningsmedel och fettersättning men har även många icke livsmedelsindustriella användningsområden bl. a. i pappers-, kosmetika-, lim-, textil-, oljeborrning- och läkemedelsindustrin. Med kemiska, fysikaliska samt Starch is a plant-derived polysaccharide with many uses in different food and non-food applications. In this thesis, the production of two novel potato starch qualities, amylopectin and high-amylose, and the modifications and the characteristics of the produced plants and starches are described. The novel potato starch qualities will find uses in e.g. the paper, adhesive, textile and packing indus

Popular Abstract in Swedish Spel och spelbräden har fått lite uppmärksamhet av forskare som undersöker de antika kulturerna. Denna avhandling samlar och analyserar arkeologiskt spelmaterial från bronsålderns Kreta, definierar forskningsfältet och presenterar ett ramverk med materialavgränsningar och typologier. Vidare undersöks spelandet som en del av socialhistorien. Varje del i avhandlingen - soThe old, world-wide phenomenon of playing board games has received little attention among scholars studying the ancient cultures. This thesis collects and analyses game-related material from Bronze Age Crete, defines the field of research and provides a framework with definitions and typologies. A further goal is to use the results of the analyses to extend beyond the archaeological material and e

Contemporary advancements in miniaturization of analytical systems have advantageously fostered development, automation, and hyphenation of a variety of sample preparation techniques. Among several downscaled extraction designs, porous synthetic polymeric membranes (such as flat sheet (FS) or hollow fiber (HF)) have been utilized for membrane-based extraction, separating two aqueous phases (as in

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 Tungmetaller i kommunala avfallsupplagExtensive use of heavy metals in modern society influences routes followed by fluxes on the surface of the Earth. The changed flow paths may be harmful for the balance of biological systems at different levels, micro-organisms, human beings and whole ecosystems, since the toxicity of heavy metals is determined by their concentrations and chemical forms. The fluxes of cadmium in Sweden and especia

The processing and disposal of sludge from wastewater treatment plants is an important topic of increasing environmental, ecological, technological, economic and social concern. The large amounts of sludge produced represent an urgent problem today, new treatment methods being very much needed. Reducing the volume of sludge can be achieved either by decreasing the amounts of it produced during the

Popular Abstract in Swedish Högt blodtryck, hypertoni, är en folksjukdom som ökar risken att insjukna i slaganfall och hjärtinfarkt. I flertalet fall är orsaken till hypertoni okänd och man talar då om primär hypertoni. Mellan 30 och 60% av blodtrycksvariationen i befolkningen bestäms av genetiska faktorer medan resten beror på omgivningsfaktorer. Primär hypertoni uppkommer sannolikt på grund av sGenetic factors are of importance for the development of primary hypertension (HT). Intrauterine growth retardation, salt sensitivity and insulin resistance are all characteristic features of individuals prone to develop HT. Monogenic forms of hypertension such as Liddle´s syndrome (LS) and Apparent Mineralocorticoid Excess (AME), and hypotension such as Gitelman´s syndrome (GIT) have recently bee

Popular Abstract in Swedish Allt eftersom fler och fler organismers totala uppsättning gener, genomet, sekvenseras ökar fokus på att kartlägga de genprodukter, proteiner, som uttrycks. Att kunna studera de proteiner som uttrycks mer eller mindre vid olika tidpunkter eller cellulära tillstånd utgör en viktig del i sökandet efter kunskap om biologiska och medicinska processer. Studier av den totala The study of the protein complement of a genome is called proteomics. Proteomics can be defined as identification, quantification and characterization of a total set of proteins expressed at different time-points or under different cellular states to provide global information about biological processes. The study of membrane proteins is a challenging area in the development of proteomic research.

Popular Abstract in Swedish Den molekylära processen under vilken DNA-information förs över till RNA-information kallas transkription. Transkription styrs främst i samverkan med många speciella molekyler som kallas transkriptionsfaktorer. Zinkfinger proteiner är en av de vanligast förekommande klasserna av reglerande proteiner i eukaryota celler där de inverkar på en mängd av cellulära aktiviteterThe molecular process under which message in DNA is relayed onto RNA is called transcription, and it accomplished through involvement of so-called transcription factors. Zinc finger proteins are one of the most abundant classes of regulatory proteins in eukaryotic cells where they play central roles in a variety of cellular activities. A classical zinc finger is a small protein motif with a simple

The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. When the maximum stress acting in a cutting tool exceeds its critical stress, which is usually determined by tool geometry

The enzyme deoxyuridine 5’-triphosphate nucleotidohydrolase (dUTPase, EC 3.6.1.23) catalyzes the hydrolysis of dUTP to dUMP and pyrophosphate. The reaction suppresses misincorporation of uracil into DNA and provides dUMP for the de novo synthesis of dTTP. dUTPase is a widespread enzyme and the fact that many viruses encode a dUTPase of their own suggests the enzyme to be important for the viral li

Popular Abstract in Swedish Evolution är förändringen av en egenskap över flera generationer i en population. För att en sådan förändring ska kunna ske måste ärftlig variation finnas i populationen. Med detta menas att en gen som påverkar en egenskap, t.ex. en fågels vinglängd, måste finnas i olika former, så kallade alleler, som har olika effekt på egenskapen (t.ex. längre eller kortare vinge). MLong-term studies of birds play an important role in the understanding of quantitative traits in natural populations. The relative ease by which individual birds can be monitored and caught in the wild enable us collect detailed information from individuals throughout their life time, sometimes from several generations in a population. In this thesis I describe the utilization of a great reed warb

För att ett företag ska kunna bli beskattat för vinsten i ett land, krävs att företaget i fråga kan anses ha ett fast driftställe i landet. Den svenska definitionen av begreppet bygger på det modellavtal som OECD har producerat. Den svenska definitionen innehåller inga specifika undantag från fast driftställe utan har istället ett övergripande krav att verksamheten ska vara förberedande eller bitrFor a company to be taxed for their profit in a state, the company has to be attributed to a permanent establishment in the state in question. The Swedish definition of a permanent establishment is inspired by the definition found in the model tax treaty of OECD. The definition found in the Swedish tax law does not contain any specific activities which are subject to exception from the term perman

As an increasing number of species drift onto the IUCN’s list of endangered species, it has become increasingly important to understand the fundamental aspects that are essential in maintaining the fitness of these threatened species. Using tracking data from 75% of a sample of Swiss juvenile Red Kites during their wintering period in Spain, various bioclimatic predictors (BCMPs) were taken into

I framställningen analyseras de straffrättsliga övervägandena i slutbetänkandet av Utredningen om självkörande fordon på väg (SOU 2018:16) ur ett brottsofferperspektiv. Brottsofferperspektivet grundar sig i viktimologisk forskning som framhåller upprättelse som ett centralt behov hos skadade individer. Brottsofferbegreppet centreras, till skillnad från överträdelser av brottsbestämmelser, kring skThis study analyses the considerations, regarding criminal culpability, of the Committee on autonomous vehicles (SOU 2018:16) from a victim’s perspective. The victim’s perspective is based on victimological research presenting redress as a clear need of victims of harm. The definition of a victim is, in this thesis, centred around the harm of an individual injured or killed by an autonomous vehicl

This master's thesis aims to investigate how libraries can continue the work for LGBTQ-inclusion after they have acquired a certification from the RFSL, including how the certification affects librarians and the library, and if that work accommodates what young people from the LGBTQ(AI)-community wants and needs from the library. The material is guided from both qualitative interviews with fiv
