21. Development of adenoviral vectors for monitoring telomerase activity in living cells
Sammanfattning : ABSTRACT Telomerase activity is a potential molecular marker for cancer and primitive cells in regenerative tissues. The most commonly used method to measure telomerase activity in cells is the telomerase reverse amplification protocol (TRAP) assay, where the protein extracts derived from homogenized cells are analysed.

22. Sustainable production of bio-energy products in the sawmill industry
Sammanfattning : One of the great challenges facing society is to convert theglobal energy system to a sustainable process. Currently, 80%of the world´s energy is supplied through the combustionof fossil fuels. Not only are the fossil resources limited, theutilisation also increases the level of greenhouse gases in theatmosphere. LÄS MER
23. Re-evaluation of methods to identify individuals with increased risk of caries
Sammanfattning : The overall aim of this thesis was to evaluate methods used to identify individuals with increased risk of coronal caries lesion development. The specific aims were to:•evaluate the accuracy of different methods used to identify individuals with increased risk of developing dental coronal caries lesions (study I)•design and pilot a novel classification system for the assessment of caries lesion progression in bitewing radiography and to report rater agreement of the system (study II)•assess intra-individual differences in biofilm acid-tolerance between different tooth surfaces and inter-individual variation as well as stability of acid tolerance over time (study III)•assess diagnostic accuracy of two established methods and a candidate method to identify adolescents with increased risk of dental coronal caries lesion development (study IV).

24. Tracking the fate of biocontrol microorganisms in the environment using intrinsic SCAR markers
Sammanfattning : Biocontrol microorganisms can be used as an alternative to conventional chemical pesticides to control plant diseases. This thesis investigated the fate and behaviour of three microbial model control agents with effect against fungal pathogens in cropping systems, and the spread of one of the model strains in bioaerosols.

25. Planteringar vid järnvägen. Funktion och organisation under stambanornas första tid
Sammanfattning : I den här licentiatuppsatsen undersöks planteringar vid de första stambanorna i Sverige mellan åren 1855–1875. När järnvägar för persontrafik började byggas i mitten av 1800-talet innebar de en stor förändring av samhället, landskapet och människors vardagsliv. LÄS MER
