  1. 21. Experimental Evolution : and Fitness Effects of Mutations

    Författare :Anna Knöppel; Dan I Andersson; Stanley Maloy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Fitness effects; mutations; S20; fis; ribosome; horizontal gene transfer; adaptation; synonymous mutations; Mikrobiologi; Microbiology;

    Sammanfattning : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. LÄS MER

  2. 22. Under the influence? Understanding media’s coverage of opinion polls and their effects on citizens and politicians

    Författare :Per Oleskog Tryggvason; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; opinion polls; public opinion; political coverage; political communication; mediatization; bandwagon effects;

    Sammanfattning : News media’s use of horse race polls is a defining feature of contemporary political reporting. This thesis investigates how the news media use these opinion polls and how this coverage can influence two of the most central actors in representative democracies: citizens and politicians.

    Sammanfattning : The main goals of this study are to identify and describe the psychological and sociological factors present in a media communication process, that influence the behaviour of consumers, advertisers and media organizations. The study focuses on the expectations and predictions of the future of media, in particular of printed local newspapers. LÄS MER

  4. 24. Transitional flow in ordered porous media

    Författare :Tobias Forslund; Staffan Lundström; Sofia Larsson; Gunnar Hellström; Krishna Pillai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Porous media; Lattice Boltzmann Method; GPU Programming; Tomographic PIV; Laser Doppler Velocimetry; Strömningslära; Fluid Mechanics;

    Sammanfattning : Porous media, here defined as any permeable structure allowing a fluid to flow through, are relevant to a multitude of engineering applications and natural processes. The observed macroscopic properties of the porous media such as mixing, heat transfer and apparent permeability are properties which are affected by the flow and especially the type of flow, or flow region.

  5. 25. Optical Methods for Tympanic Membrane Characterisation : Towards Objective Otoscopy in Otitis Media

    Författare :Mikael Sundberg; Tomas Strömberg; Ton van Leeuwen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical Methods; Spectroscopy; Surface Curvature; Monte Carlo; Tympanic Membrane; Otitis Media; Medical engineering; Medicinsk teknik;

    Sammanfattning : Otitis media, which is an upper respiratory tract infection that affect the middle ear, is the second most common disease in childhood, outnumbered in prevalence only by the common cold. Diagnosis of middle ear inflammation is often performed in the primary healthcare where the normal procedure involves anamnesis and physical examination of the tympanic membranes (TM) of the patient, usually be means of otoscopy.
