A circular economy approach for sustainable feed in Swedish aquaculture: A nutrition and physiology perspective
(2019-10-25)One major challenge in aquaculture is the issue of fishmeal replacement as a protein source in aquafeeds. It is agreed that the rate of demand has now outpaced the rate of supply due to the rapid expansion of aquaculture. ... -
A contribution to the design and analysis of phase III clinical trials
(2013-11-08)Clinical trials are an established methodology for evaluation of the effects of a new medical treatment. These trials are usually divided into several phases, namely phase I through IV. The earlier phases (I and II) are ... -
A Holistic View on Aquaporins: Production, Structure, Function and Interactions
(2020-10-21)Aquaporins are specialised membrane proteins, which regulate the water homeostasis of cells. In eukaryotic organisms, this process is tightly regulated, and aberrations in aquaporin functionality lead to severe pathologies ... -
A Play of Light and Spins: Excitation and Detection of Non-linear Magnetization Dynamics using Light
(2020-09-02)The excitation and detection of magnetization dynamics play key roles in the field of spintronics and magnonics. In this thesis, we investigate a contactless method of exciting nonlinear magnetization dynamics using a ... -
A Soot Transformation Study: Interactions Between Soot, Sulfuric Acid and Secondary Organic Aerosol (SOA)
(2018-01-19)Atmospheric black carbon (BC), generally called soot, is the most important aerosol component that warms the Earth’s climate significantly, and reducing atmospheric soot level has been proposed as a strategy for near-term ... -
A two-stage numerical procedure for an inverse scattering problem
(Chalmers University of Technology and University of Gothenburg, 2015)In this thesis we study a numerical procedure for the solution of the inverse problem of reconstructing location, shape and material properties (in particular refractive indices) of scatterers located in a known ... -
A Waterborne Colloidal Model System Consisting of Fluorinated Spheres Bearing Grafted PEG: Synthesis, Characterization and Properties
(2016-01-08)Model systems have expanded our knowledge of numerous phenomena in Colloid Science, such as the appearance of glasses, order-disorder transitions involving crystals and attraction induced formation of gels. So far, the ... -
Absolute Asymmetric Synthesis
(2010-02-03)Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of ... -
Absolute Asymmetric Synthesis
(2011-04-18)Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of ... -
Acclimation of boreal Norway spruce to climate change: Empirical and modelling approaches
(2019-09-04)The findings of this thesis have important implications for the projections of future carbon and water fluxes for the boreal region. The observed boreal longterm acclimation responses of respiration and stomatal regulation ... -
Active Matter in a Critical State: From passive building blocks to active molecules, engines and droplets
(2020-12-19)The motion of microscopic objects is strongly affected by their surrounding environment. In quiescent liquids, motion is reduced to random fluctuations known as Brownian motion. Nevertheless, microorganisms have been able ... -
Adaptation and Protein Quality Control Under Metalloid Stress
(2015-04-22)Toxic metals and metalloids are emerging as major environmental pollutants, having ecological consequences as well as being linked to a broad range of degenerative conditions in animals, plants and humans. While the toxicity ... -
Adaptation to the Baltic Sea – the case of isopod genus Idotea
(2013-05-16)The three marine isopods of the genus Idotea: I. balthica, I. chelipes and I. granulosa have an important functional role as meso-grazers in the Baltic food web. These meso-grazers are key species in the Fucus belt and in ... -
Advances in Holographic Optical Trapping
(2013-05-05)Holographic optical trapping (HOT) is a technique for non-invasive dynamic anipulation of multiple microscopic objects, which has been used for many applications in the life sciences during the past decade. The technique ... -
Advances in Membrane Protein Structural Biology: Lipidic Sponge Phase Crystallization, Time-Resolved Laue Diffraction and Serial Femtosecond Crystallography
(2013-05-08)Membrane proteins carry out many essential tasks in cells such as signaling and transport, or function as electron carriers in photosynthesis and cellular respiration. The aim of this thesis has been to develop new and ... -
Advancing Evolutionary Biology: Genomics, Bayesian Statistics, and Machine Learning
(2020-11-20)During the recent decades the field of evolutionary biology has entered the era of big data, which has transformed the field into an increasingly computational discipline. In this thesis I present novel computational method ... -
Age-class interactions in Atlantic salmon and brown trout: Effects on habitat use and performance
(2010-05-06)This thesis investigates the underlying mechanisms and the density-regulatory effects of age-class interactions, using juvenile Atlantic salmon (Salmo salar L.) and brown trout (Salmo trutta L.) as study species. Field ... -
Ageing and Conservation of Silk - Evaluation of Three Support Methods Using Artificiallay Aged Silk
(2015-10-19)The general aim of this thesis is to evaluate common remedial conservation support methods used in the conservation treatments of fragile silk costumes that have experienced physical damage. It is based on five papers. ... -
