  1. 1. Early host cell interactions and antivirals against ocular adenoviruses

    Författare :Rickard Storm; Niklas Arnberg; Saw See Hong; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; Virus host interactions; Antivirals; Sialic acid; Integrins; Epidemic keratoconjuntivitis;

    Sammanfattning : Viruses are common causative agents of ocular infection among humans. Epidemic keratoconjuntivitis (EKC) is a severe and contagious ocular disease with reported outbreaks worldwide. It is estimated that this disease affects 20-40 million individuals every year, which leads to huge socioeconomic costs for the affected countries. LÄS MER

  3. 2. Sågarnas sång : folkligt musicerande i sågverkssamhället Holmsund 1850-1980

    Författare :Alf Arvidsson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ethnomusicology; working-class culture; workers music; soundscape; amateur music; popular music; dancing; concerts;

    Sammanfattning : The aim of this dissertation is to analyze the public music-making by locals in Holmsund 1850—1980, and to explain the great variety of musical forms in hope to thereby illuminate the importance of local music-making for the workers' musical taste, but also how workers' musical aesthetics were affected by a more general working-class culture. The variety of musical forms is explained according to John Blacking's distinction between change of musical system, and variation and innovation within a musical system. LÄS MER

  4. 3. Quantum acoustics with superconducting circuits

    Författare :Gustav Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; superconducting qubits; cluster states; SAW; two-level systems; circuit QED; giant atoms; two-mode squeezing; surface acoustic wave; quantum acoustics; hybrid quantum systems;

    Sammanfattning : The past 20 years has seen rapid developments in circuit quantum electrodynamics, where superconducting qubits and resonators are used to control and study quantum light-matter interaction at a fundamental level. The development of this field is strongly influenced by quantum information science and the prospect of realizing quantum computation, but also opens up opportunities for combinations of different physical systems and research areas.

  5. 4. Studies of acoustic waves, noise and charge pumping using single-electron devices

    Författare :Martin Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single-electron pump; single-electron transistor; surface acoustic wave; single-electron devices; charge pumping; TLF; SINIS turnstile; electrometer; two-level fluctuator; single-photon detector; noise; SAW; SET;

    Sammanfattning : This thesis covers a range of experiments on single-electron devices, electrical circuits that utilize the discreetness of the electron charge. The Single-Electron Transistor (SET) is of special importance among these, being the most sensitive electrometer demonstrated, and sufficiently mature to serve as a building block in sensors and detectors for physical phenomena that can be transformed into charge signals.
