On the quantitative analysis of electronic energy transfer/migration in proteins studied by fluorescence spectroscopy
Author(s) :
Isaksson, Mikael
Description :
Two recently developed theories of electronic energy transfer/migration were for the first time applied to real protein systems for extracting molecular distances. The partial donor-donor energy migration (PDDEM) is an extension to the previously developed donor-donor energy migration (DDEM, F Bergs...

Modeling of glyphosate and metal-glyphosate speciation in solution and at solution-mineral interfaces
Author(s) :
Jonsson, Caroline
Description :
Glyphosate (N-(phosphonomethyl)glycine, PMG, H3L) is a widely used organophosphorous herbicide. It interacts with metal ions and mineral surfaces, which may affect its mobility, degradation and bioavailability in the environment. However, these interactions are far from fully understood. This thesis...

Synthesis of β-turn and pyridine based peptidomimetics
Author(s) :
Blomberg, David
Description :
Despite the unfavorable pharmacokinetic properties associated with peptides, they are still of great interest in drug development due to a multitude of interesting biological functions. The development of peptidomimetics strives to maintain or improve the biological activity of a peptide concurrentl...

Synthesis and optical characterization of optical power limiting platinum(II) acetylides
Author(s) :
Carlsson, Marcus
Description :
Interactions between light and a molecule can result in reversible or irreversible changes in properties of both the light and the molecule. Of the many known interactions, nonlinear absorption is a process in which an intense light signal, for instance from a laser, can be moderated. This can be ma...

Hazard screening of contaminated sites : bioavailable fractions and biological in vitro tools
Author(s) :
Ragnvaldsson, Daniel
Description :
The environmental bioavailability of contaminants, rather than their total concentrations in the soil compartment play a decisive role for the risks associated with contaminated sites. Various soil constituents and abiotic conditions have strong influence on bioavailability, which may vary substanti...

Hydrophilic Separation Materials for Liquid Chromatography
Author(s) :
Hemström, Petrus
Description :
The main focus of this thesis is on hydrophilic interaction chromatography (HILIC) and the preparation of stationary phases for HILIC. The mechanism of HILIC is also discussed; a large part of the discussion has been adapted from a review written by me and professor Irgum for the Journal of Separati...

The Role of Proteases in Plant Development
Author(s) :
Garcia-Lorenzo, Maribel
Description :
Proteases play key roles in plants, maintaining strict protein quality control and degrading specific sets of proteins in response to diverse environmental and developmental stimuli. Similarities and differences between the proteases expressed in different species may give valuable insights into the...

Solubility and Surface Complexation Studies of Apatites
Author(s) :
Bengtsson, Åsa
Description :
Apatites are a diverse class of phosphate minerals that are important in a great variety of natural and industrial processes. They are, for example, used as raw material in fertiliser production and in the remediation of metal-contaminated soils. Hydroxyapatite Ca5(PO4)3OH, (HAP) and fluorapatite Ca...

Synthesis and modifications of materials for separation science
Author(s) :
Nordborg, Anna
Description :
This thesis deals with the preparation of materials for use in separation science and their surface modification by grafting. The overall aim is the preparation of diverse materials by combination of a set of developed tools. Included in the thesis is the synthesis of monolithic media using non-trad...

Latent variable based computational methods for applications in life sciences : Analysis and integration of omics data sets
Author(s) :
Bylesjö, Max
Description :
With the increasing availability of high-throughput systems for parallel monitoring of multiple variables, e.g. levels of large numbers of transcripts in functional genomics experiments, massive amounts of data are being collected even from single experiments. Extracting useful information from such...
