  2. 1. Atmospheric circulation regimes and climate change

    Author : Jenny Brandefelt; Erland Källén; Jonas Nycander; Vim Verkley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atmospheric large-scale circulation; greenhouse gas forcing; climate sensitivity; Meteorology; Meteorologi;

    Abstract : The Earth's atmosphere is expected to warm in response to increasing atmospheric concentrations of greenhouse gases (GHG). The response of the Earth's complex and chaotic climate system to the GHG emissions is, however, difficult to assess. In this thesis, two issues of importance for the assessment of this response are studied. READ MORE

  4. 2. Simulation of collective phenomena in microswimmer suspensions

    Author : Dora Bardfalvy; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Collective motion is ubiquitous in biological and synthetic systems across manylength- and timescales. On the macroscopic scale, examples include schools of fish, herds of sheep and flocks of birds. On the microscopic scale, bacteria, algae and synthetic self-propelled particles exhibit a range of collective phenomena. READ MORE

  5. 3. Mathematical models of biological interactions

    Author : Linnéa Gyllingberg; David J.T. Sumpter; Kolbjörn Tunström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Mathematical models are used to describe and analyse different types of biological interactions.  From self-propelled particle models capturing the collective motion of fish schools to models in mathematical neuroscience describing the interactions between neurons to individual-based models of ecological interactions.

  6. 4. The photo-diary and follow-up appointment on the ICU: Giving back the time to patients and relatives. : A descriptive and interventional study

    Author : Carl G Bäckman; Sten Walther; Folke Sjöberg; Lotti Orwelius; Lars Berggren; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background: Patients on the ICU often spend a great deal of their time either unconscious or heavily sedated. When they return from the zone between life and death they are often in a state of confusion where dreams and delusions are intertwined with reality and it is not always easy to distinguish them apart.

  7. 5. Dynamics of complex magnetic systems

    Author : Kristian Jonason; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : Dynamic magnetic properties of disordered and frustrated magnetic systems have beenexperimentally investigated utilising SQUID (Superconducting Quantum Interference Device)magnetometry. The studied systems are spin glasses, reentrant ferromagnets, reentrantantiferromagnets and diluted Ising antiferromagnets. READ MORE
