Quantitative Genetics and Genome Structure in a Wild Population: the Use of a Great Reed Warbler Pedigree

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

Managing short-term efficiency and long-term development through industrialized construction

There is a strong need for a productive and innovative infrastructure sector because of its monetary value and importance for the development of a sustainable society. An increased level of industrialization is often proposed as a way to improve efficiency and productivity in construction projects. In prior literature on industrialized construction, there are however neither many studies addressin

Laborativa analyser av keramik från ugnarna i Hellum, Barmer och Kragelund

Laboratory analyses of the potsherds from Hellum, Barmer and Kragelund were performed in order to study the manufacturing techniques at the different sites. During the planning of the project it was suggested that the reconstructed pots to be fired in the kilns should not only have a shape resembling the original products, but also have a raw material composition as similar as possible to the medi

Fänad i helgade grifter : svensk djurgravpoesi 1670–1760

Popular Abstract in SwedishDjurgravpoesi är en form av tillfällespoesi och en subgenre till den vanliga begravningspoesin, som skrevs över människor. Den som skapade förutsättningarna för att denna diktart skulle få fäste i Sverige var änkedrottning Hedvig Eleonoras hovpoet Erik Lindschöld; hans gravdikter över änkedrottningens tikar är sannolikt skrivna på 1670-talet. Här börjar en linje som går This dissertation examines a hitherto neglected genre in Swedish poetry of the 17th and 18th centuries: the animal epitaph. From 1670 to 1760 a considerable number of such poems were composed by several of the leading poets of the day. In this dissertation, besides tracing the history of the genre back to its origins in the ancient Greek epigram, I am chiefly concerned with the functions that the

Recrystallisation behaviour of native and processed waxy maize starch in relation to the molecular characteristics

Molecular characteristics were determined for native waxy maize starch and maize starch modified in different way (by mechanical treatment or/and acid hydrolysis). Recrystallisation behaviour was studied. Methods used in this study were MALLS, HPAEC-PAD, NMR, DSC, SEM, light microscopy. Five starch materials were subjected to storage under the same conditions in the presence of water (70 w/w%). Mo

Numerical and experimental investigation of backdraft

The article describes full-scale backdraft experiments in a shipping container using methane as a fuel. Numerical modelling has followed the experimental setup. The numerical simulations show the initial gravity current, the ignition, the spreading of flame in the enclosure, the external fireball, and the subsequent decay. The Detached Eddy Simulation (DES) approach has been used to model turbulen

Defying aches and revaluating daily doing: Occupational perspectives on adjusting to chronic pain.

Abstract The aim of this study was to investigate how people with chronic pain experience their daily doing, with a special focus on possible adjustment to pain and altered life conditions in order to cope with pain and maintain well-being. In-depth interviews were guided by themes concerning daily occupation, ways to maintain well-being, and future expectations. Using qualitative content analysis

Phase separation, aggregation and gelation of a charged helixforming polysaccharide in aqueous salt solution

Popular Abstract in Swedish De senaste åren har jag ägnat åt att undersöka en speciell typ av gelbildare: kappa-carrageenan. Kappa-carrageenan kan användas för att göra gelé men används också i annan mat t.ex. efterrätter och glass, för att ge konsistens. När man vill göra en gel av kappa-carrageenan blandar man ut lite pulver i vatten och kokar sedan upp det hela. När blandningen kyls av kommer dThe phase behaviour and gelation of the anionic polysaccharide kappa-carrageenan (KC) in different salt solutions was studied. The specific site binding of certain anions and certain cations to the KC helix was used as a means of controlling the interactions. In the presence of a binding anion (I-) the charge density of the helix increases and the aggregation of helices, and thereby the gelation,

Molecularly Imprinted Polymers at the Nanometric Scale: Synthetic Receptors for Chemical Sensors

In this thesis, polymerisation techniques or deposition methods have been developed permitting the creation of thin molecularly imprinted polymer (MIP) films or patterns and their interfacing with transducer surfaces for biosensor applications. The creation of ultra thin films has been achieved using two different techniques, spin-coating and in-situ polymerization of thin films of monomers conta

Phase metrology with multi-cycle two-colour pulses

Strong-field phenomena driven by an intense infrared (IR) laser depend on during what part of the field cycle they are initiated. By changing the sub-cycle character of the laser electric field it is possible to control such phenomena. For long pulses, sub-cycle shaping of the field can be done by adding a relatively weak, second harmonic of the driving field to the pulse. Through constructive and

Theoretical Modeling of Water Exchange on [Pd(H2O)4]2+, [Pt(H2O)4]2+, and trans-[PtCl2(H2O)2]

SynopsisOptimized structures describing key features of the potential energy surface for water exchange at three planar d8 centers have been calculated using ab initio density functional theory. The local density approximation (LDA), including relativistic corrections for Pt, gives good agreement with the available experimental ground state structural data. LDA binding energies together with expli

Potential Influence of Diet on Bomb-Pulse Dating of Human Plaque Samples

The radiocarbon concentration of different atherosclerotic plaque fragments obtained from 20 patients in Portugal, operated in 2000-2001, has been measured in order to define the year of plaque formation. A difference of 1.8-15 yr was observed, with the mean and median both 9 yr, between the bomb-pulse date estimated with the CALIBomb software and the operation date. Stable isotope (delta C-13 and

Accounting for interannual variability in agricultural intensification : The potential of crop selection in Sub-Saharan Africa

Providing sufficient food for a growing global population is one of the fundamental global challenges today. Crop production needs not only to be increased, but also remain stable over the years, in order to limit the vulnerability of producers and consumers to inter-annual weather variability, especially in areas of the world where the food consumed is mainly produced locally (e.g. Sub Saharan Af

Återförsäkringspolitik? En kvalitativ fallstudie om Sveriges beslut att delta i Operation Inherent Resolve

Has Sweden abandoned its traditions on what foundations military interventions are decided upon, such as a solid UN mandate, valid framework organizations and inviolable legal status of its personnel? In June 2015 Sweden decided to participate in Operation Inherent Resolve in Iraq. Twelve days later a new defence-policy was decided, focusing on national capabilities. Furthermore, government was cr

The Wastefulness of the Environmental Movement - An Investigation into Sustainable Activism

This thesis examines how the Climate Justice Movement in Germany is set up today and how activists relate to and feel about their activism. Specifically, factors are investigated that make people feel unhappy about their activism or even leave the movement. Furthermore, potential changes of the movement in order to become a healthier and more sustainable environment for activists are suggested. Pa

Strategiskt användande av EU:s viseringsregelverk - En möjlighet till ny prövning om uppehållstillstånd efter att ett av- eller utvisningsbeslut vunnit laga kraft?

Den svenska migrationsrätten bygger på principen att en utlänning enbart får en chans att ansöka om uppehållstillstånd från Sverige. Om denna ansökan senare misslyckas så ska utlänningen enligt huvudregel meddelas ett av- eller utvisningsbeslut. När ett sådant beslut blir verkställbart kommer allt som vederbörande därefter anför till stöd för uppehållstillstånd prövas och handläggas utifrån utlännSwedish migration law is built on the principle that an alien only has one opportunity to apply for a residence permit from Sweden. If the application is rejected then the alien should as a rule be informed of the expulsion decision. When the decision becomes enforceable, subsequent assertions referred to by the applicant in support of his/her residence permit are assessed and processed pursuant t

Skydd för fotografier tagna av kamerafällor? - En undersökning av hur fotografier skapade med begränsad mänsklig inblandning kommer att behandlas inom upphovsrätten och inom upphovsrättens närstående rättigheter

Upphovsrätten utmanas ständigt av nya teknologiska fenomen. På senare tid har den tekniska utvecklingen möjliggjort att alster som tidigare var beroende av mänskligt skapande kan åstadkommas genom mer eller mindre automatiserade processer. I denna kategori finner vi kamerafällor som förenklat kan beskrivas som kameror som antingen ställs in för att ta fotografier konstant eller vid ett visst tidsiCopyright law is constantly challenged by new technological phenomena. Recently, new technology has enabled the making of creations through more or less autonomous processes. Some of these creations were previously dependent on human creativity for its existence. Situated in this category are camera traps. Camera traps can somewhat simplified be explained as cameras that are either set to take pic

Metadata filtering for secure and high performance user identification

På grund av begränsningar i existerade biometriska matchningsalgorithmer är det i dagsläget en mycket svår uppgift att utföra pålitlig identifiering med en stor mängd registrerade användare. Detta arbete undersöker om det är möjligt att utföra en pålitlig identifiering genom att först reducera antalet möjliga kandidater genom att använda tillgänglig information i en filtreringsprocess. Detta arbeThe aim of this thesis is to investigate the possibility of enabling biometric identification given a large number of enrolled users. This area is relatively unexplored compared to biometric authentication where a fingerprint template is compared against just a few number of templates. The selected approach is to use auxiliary information available during an identification. This information will b

Effects and safety of selected antagonistic bacteria against Escherichia coli in leafy green vegetables

We live in a busy world, where the demand of ready-to-eat (RTE) salad products has increased rapidly in a relatively short time. Despite of being an easy and fast way to add more vegetables to the daily diet, RTE salads have a serious underlying risk and the amount of vegetable-derived foodborne disease outbreaks has been increasing. The aim of the present study is to protect plants against contam
