Extreme Value Analysis of Huge Datasets: Tail Estimation Methods in High-Throughput Screening and Bioinformatics
(2011-10-13)This thesis presents results in Extreme Value Theory with applications to High-Throughput Screening and Bioinformatics. The methods described here, however, are applicable to statistical analysis of huge datasets in general. ... -
Two-Electron Excitations in Negative Ions
(2011-10-07)The main goal of this work has been to increase the knowledge of electron-electron correlation through experimental studies of negative ions. Negative ions are atoms or molecules to which an extra electron has been attached. ... -
Experimental studies of cluster ions containing water, ammonia, pyridine and bisulphate
(2011-10-06)Molecular cluster ions are fascinating subjects of study. Bridging the size gap between molecules and bulk, they often display non-trivial size dependent behaviour and properties. As an example, for some cluster types there ... -
Synthesis of Novel Inhibitors of IdeS, a Bacterial Cysteine Protease Including Studies of Stereoselective Reductive Aminations
(2011-09-30)Abstract The cysteine protease IdeS is an IgG degrading enzyme secreted by the bacterium Streptococcus pyogenes to evade the human immune system. In this thesis several inhibitors of IdeS have been synthesized and ... -
Instruments for reaching climate objectives. Focusing on the time aspects of bioenergy and allocation rules in the European Union's Emission Trading System
(2011-09-29)The Europeans Union’s (EU’s) climate and energy strategy aims at reducing the emissions of greenhouse gases (GHG) by 20 % (compared to 1990) and to increase the share of renewable energy to 20 % by the year 2020. Increased ... -
Chemical and Dermatological Aspects of UV-absorbing Compounds
(2011-09-27)ABSTRACT The sun’s UV radiation is necessary for the existence of life on earth. However, too much UV exposure can lead to the development of skin cancer. Therefore, sunscreens are often used by the general population ... -
From Proteomic Analysis to Biomarker Application - Studies of Carbonyl Reductase in Fish
(2011-09-22)Many anthropogenic substances are present in the aquatic environment, but there is limited information on how this combination of chemicals affects exposed wildlife. To assess the impact of chemicals, a biomarker approach ... -
On the Electrolyte Induced Aggregation of Concentrated Silica Dispersions - An Experimental Investigation Using the Electrospray Technique
(2011-09-08)Gels are weak, solid-like structures that arise when colloidal particles aggregate to form a network of particle clusters. A variety of colloidal systems that are important scientifically as well as in industrial applications ... -
Asymptotics and dynamics in first-passage and continuum percolation
(2011-09-06)This thesis combines the study of asymptotic properties of percolation processes with various dynamical concepts. First-passage percolation is a model for the spatial propagation of a fluid on a discrete structure; the ... -
Practical, Flexible programming with Information Flow Control
(2011-08-15)Mainstream mechanisms for protection of information security are not adequate. Most vulnerabilities today do not arise from deficiencies in network security or encryption mechanisms, but from software that fails to provide ... -
PEER-PRODUCTION FOR COLLABORATION BETWEEN ACADEMICS AND PRACTITIONERS
(2011)The purpose of this article is to suggest commons-based peer-production as a form of work that can help bridge the gap between research and practice in LIS. The research design is based on two in-depth and longitudinal ... -
The Carbon Dioxide System in the Baltic Sea Surface Waters
(2011-05-26)The concentration of carbon dioxide (CO2) in the atmosphere is steadily increasing because of human activities such as fossil fuel burning. To understand how this is affecting the planet, several pieces of knowledge of the ... -
Analysis of phospholipids in cellular membranes with LC and imaging mass spectrometry
(2011-05-20)Imaging mass spectrometry enables the creation of molecule specific images from the surface of a solid sample in vacuum. To solve the issue of bringing single cells into vacuum without altering their native distribution ... -
Electronic Control of Flexural Nanowire Vibrations
(2011-05-19)“Nanoelectromechanical systems” (NEMS) are nanometer-sized mechanical structures coupled to electronic devices of comparable size. The coupling between mechanical and electronic degrees of freedom, combined with their ... -
The Mesoproterozoic Hallandian event - a region-scale orogenic event in the Fennoscandian Shield
(2011-05-19)The Sveconorwegian Province occupies the southwestern part of the Fennoscandian Shield. The easternmost tectonic unit of the Province is the 1710-1660 Ma parautochthonous Eastern Segment, which bears the imprint of at least ... -
Unravelling the complexity of cold acclimation in plants
(2011-05-19)Many plants respond to low non-freezing temperatures by increasing their freezing tolerance in a process known as cold acclimation. Microarray studies have shown that hundreds of genes are differentially expressed during ... -
Colloidal interactions obtained from total internal reflection microscopy measurements and scattering data
(2011-05-18)The scattering of radiation can be used to extract information about the interactions between colloidal (10^{-7}-10^{-3} cm radius) particles suspended in liquids. As colloidal interactions incorporate entropic effects ... -
Inertial collisions in random flows
(2011-05-13)In nature, suspensions of small particles in fluids are common. An important example are rain droplets suspended in turbulent clouds. Such clouds can start to rain very quickly and the reason for this is still not fully ... -
Integrated biomechanical, electronic and topographic characterization of titanium dental implants
(2011-05-11)Titanium dental implants are medical devices used to restore the function entailed with the loss of one or several teeth. To obtain successful function over long periods, the dental implants must be sufficiently anchored ... -
Protein Damage Control during Embryonic Stem Cell Differentiation: Role of the Proteasome
(2011-05-11)During the lifespan of organisms ranging from yeast to humans, there is an accumulation of macromolecular damage. However, these organisms produce youthful progeny with low damage levels. This thesis focuses on how this ...
