Salting-out of Colloidal Latex Particles Grafted with Poly(ethylene glycol)
(2020-01-15)Colloidal particles dispersed in a medium are important both in nature and in industry. The stability of colloidal particles is determined by the interactions between them and can be improved by steric stabilization. There ... -
Samarium(II)-mediated reactions in organic synthesis - method development and mechanistic investigation
(2010-04-07)This thesis describes the development of methods using divalent samarium reagents in organic synthesis. The main focus is placed on functional group reductions, but reductive formation of carbon-carbon bonds has also been ... -
Scale-worm Systematics (Annelida, Polychaeta)
(2013-02-07)Paper I. Scale-worms are segmented worms. They can be found in all marine benthic habitats, including about 1200 species and over 200 genera. There has been little known about the phylogeny of this group and this study is ... -
Seagrass Wasting Disease Impact of abiotic factors and chemical defense
(2017-12-04)Eelgrass, Zostera marina, is the dominant seagrass species in the northern hemisphere, and forms large meadows that provide several important ecosystem services. In the 1930s about 90% of the Z. marina populations in the ... -
Seals and fisheries: a study of the conflict and some possible solutions
(2011-04-08)Interaction between seals and fisheries along the Swedish coast has serious environmental and economic consequences. This thesis describes the conflict as it affects four different small-scale coastal fisheries; the eel ... -
Seaweed Invasions and Novel Chemical Defences
(2012-11-08)Biological invasions pose a risk to the biodiversity and the functioning of ecosystems in invaded areas. The reasons why some introduced species become dominant and widespread in their new environments is still largely an ... -
Seaweeds as a future protein source: innovative cultivation methods for protein production
(2023-10-20)As the global population is projected to reach approximately 10 billion people by 2050, it is estimated that we will need to produce up to 60% more food compared to 2010. Although the current food production system contributes ... -
Secondary Organic Aerosols: Composition, Gas-to-Particle Partitioning and Physical Properties
(2019-02-21)Atmospheric aerosols influence our climate and air quality. Aerosol particles in the atmosphere are transformed through many different physical and chemical reactions. A substantial fraction of the particles in the ... -
Sedimentology and Geomorphology of Glacial Landforms in Southern Sweden
(2021-02-26)Ice sheets are disintegrating due to global warming. One factor controlling ice-sheet behavior is the processes active beneath the ice sheet. In particular, processes connected to glacial meltwater drainage are essential ... -
Selectivity in the chlorate process: Hydrogen evolution and hypochlorite reduction on deposited chromium oxide/hydroxide
(2018-02-22)Abstract Production of chlorate is dependent of using sodium dichromate as a component in the electrolyte. Dichromate provides selectivity by forming a Cr(III) oxide-like film on the cathodes. Without dichromate, unwanted ... -
Selectivity of dopamine D1 and D2 receptor agonists – A combined computational approach
(2012-10-26)Dopamine (DA) is an endogenous neurotransmitter acting in the central nervous system. DA plays a key role in many vital brain functions such as behavior, cognition, motor activity, learning, and reward. Dopamine receptors ... -
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 ... -
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 ... -
Sexual signalling and noise pollution - implications for courtship behaviour and reproductive success in two vocal species of marine gobies
(2017-08-24)Many marine animals use acoustic signals to mediate social interactions. Acoustic cues and signals are especially important in water because sound is unique as a sensory modality propagating with little attenuation over ... -
Sharp bounds on the height of some arithmetic Fano varieties
(2023)In the framework of Arakelov geometry one can define the height of a polarized arithmetic variety equipped with an hermitian metric over its complexification. When the arithmetic variety is Fano, the complexification is ... -
Shipworm ecology in Swedish coastal waters
(2015-03-11)Shipworms (Teredinidae) are marine bivalves adopted for boring into submerged wood, which they efficiently fragmentize and consume. They thereby perform a vital ecosystem service, yet simultaneously they cause extensive ... -
Signal Transduction in Photoreceptor Proteins
(2017-10-26)The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals ... -
Simplified Nonsense: New Methods for Interrogating NMD
(2023-02-20)Nonsense mediated decay (NMD) is a pathway that regulates RNA turnover. Since its discovery, this pathway has been implicated in a variety of cellular processes ranging from differentiation to the restriction of viral ... -
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 ...
