Traditionell kalkbränning på Gotland
(Hantverkslaboratoriet, Göteborgs universitet, 2012)Gotländsk kalk har bränts till murning, putsning och avfärgning i obruten hantverkstradition under minst 1000 år. I Buttle socken på Gotland upphörde traditionen i mitten av 1950-talet då den sista kommersiella hantverksmässiga ... -
Kunskapsintegrering med informationssystem i professionsorienterade praktiker
(2012-06-01)Den här avhandlingen utgår ifrån ett professionsorienterat perspektiv på användning av informationssystem. Informationssystem för kunskapsintegrering i professionsorienterade arbetspraktiker innebär en dynamik för styrning ... -

Simulated and observed change of precipitation and temperature in Europe with focus on the Greater Baltic Area
(2012-05-24)The regional climate of the Greater Baltic Area is complex and varies at a multitude of scales in space and time. This thesis contributes to increased understanding of climate change and climate variability in this area ... -
Fluxes and transformation of carbon in the Siberian shelf seas under changing environment
(2012-05-16)The Arctic is especially vulnerable to the increased air temperature caused by emissions of greenhouse gases to the atmosphere, carbon dioxide being one of them. In this thesis, both fieldwork and modelling of the East ... -
Mechanistic Insights into Transition Metal Oxide Catalyzed Water Oxidation
(2012-05-14)A binuclear mechanism was proposed and evaluated by means of Density Functional Theory calculations. The central reaction steps were found to be the oxidation of the transition metal TM-OH moieties to TM=O and the subsequent ... -
Okounkov bodies and geodesic rays in Kähler geoemtry
(2012-05-10)This thesis presents three papers dealing with questions in Kähler geometry. In the first paper we construct a transform, called the Chebyshev transform, which maps continuous hermitian metrics on a big line bundle to ... -
Carbon Dioxide and Water Vapour Exchange within a Norway Spruce Canopy
(2012-05-04)Terrestrial ecosystems can act both as sinks and sources in the global carbon cycle. Forests are an important part of this system and a good understanding of their carbon balance is essential for assessments of the future ... -
Self-organization of nanoparticles - implications for interface biology
(2012-05-03)Cells bind to their surroundings via proteins displayed on the cell surface. These interactions support the cells and are important for many cellular processes, e.g. cell migration during morphogenesis, wound healing and ... -
Stress, Homeostasis and Robustness: Molecular and Systems Level Analysis in Yeast
(2012-05-02)Abstract Cells constantly encounter stress due to alterations in the external milieu or internal parameters. However, cells are robust to such changes and maintain homeostasis. Using the yeast Saccharomyces cerevisiae as ... -
Osmoregulation at different stages of the yeast life cycle
(2012-05-02)The ability to adapt to changing and potentially harmful conditions in the surrounding environment is crucial for fitness and survival of all living cells; in particular unicellular organisms, since they are frequently ... -
Reproducing Traditional Discourses of Teaching and Learning Mathematics: Studies of Mathematics and ICT in Teaching and Teacher Education
(2012-04-16)This thesis is primarily concerned with the effects of education for future teachers in the context of the Swedish teacher training (Government Bill 1999/2000:135 2000). It belongs to a theoretical tradition in which the ... -
Infidelity in Birds – Causes and Consequences of Extra-pair Paternity
(2012-04-13)Forty years ago, more than 90% of bird species were classified as monogamous and not very exciting systems for studies of e.g. sexual selection. Since then, the discovery of extra-pair paternity (EPP) in more than 75% ... -
Hydrolytic Synthesis and Physicochemical Properties of TiO2 Nanoparticles: Fundamentals and Applications
(2012-04-13)Titanium dioxide (TiO2) nanoparticles were synthesized via the hydrolysis of TiCl4 in order to produce clean, surfactant-free oxide surfaces. By controlling the synthesis and aging conditions, stable particles with ... -
Design and Synthesis of Potential Aminoacyl-tRNA Synthetase Inhibitors
(2012-04-12)Aminoacyl-tRNA synthetases (aaRSs) are essential enzymes present in all living organisms, their catalytic activity is involved in the translation of the genetic code into functional proteins and they are potential targets ... -
Playing for Togetherness - Designing for Interaction Rituals through Gaming
(2012-04-11)can design facilitate togetherness through games? Seeing the outcomes of a successful interaction ritual – positive emotional energy and a sense of group solidarity – as the main components of the togetherness of games, ... -
Self Oscillations and Cooling of Carbon Based NEMS Devices
(2012-04-10)We investigate the electromechanical properties of a number of system geometries featuring a doubly clamped Carbon Nanotube or Graphene sheet with a deflection sensitive resistance and an electronic feedback in the form ... -
Tales of the flying earth: The effect of host flyways on the phylogeny of shorebird lice (Phthiraptera: Ischnocera)
(2012-04-05)On the wings, bodies, and heads of most birds there are lice. These lice spend their whole lives on their host, with the exception of the few lice that get the opportunity to transfer from one host to another, typically ... -
The Effects of Temperature on Gut Blood Flow and Gut Motility in Fish
(2012-03-09)In order for a fish to grow and thrive, the gut must function efficiently. This is achieved through a range of processes, including controlled patterns of gut motility and modifications in gut blood flow. How these processes ... -
Instructional technologies in science education: Student´s scientific reasoning in collaborative classroom activities
(2012-03-08)This study originates from an interest in how students interpret scientific con-cepts demonstrated with animated instructional technologies. Currently, science education makes use of diverse kinds of instructional methods. ...
