1. Inductively Coupled Plasma Atomic Emission Spectrometry : Exploring the Limits of Different Sample Preparation Strategies
Sammanfattning : This thesis describes two different sample preparation strategies for inductively coupled plasma atomic emission spectrometry (ICP-AES), and their ability regarding multi element quantification in complex samples. Sensitivity, repeatability, reproducibility and accuracy were investigated. LÄS MER
2. Hygiene aspects of the biogas process with emphasis on spore-forming bacteria
Sammanfattning : Biogas is a renewable source of energy which can be obtained from processing of biowaste. The digested residues can be used as fertiliser. Biowaste intended for biogas production contains pathogenic micro-organisms. A pre-pasteurisation step at 70°C for 60 min before anaerobic digestion reduces non spore-forming bacteria such as Salmonella spp. LÄS MER
3. Processing of berries – Effects on functionality, stability and bioactivity of anthocyanins
Sammanfattning : Berries are rich natural sources of anthocyanins, water-soluble pigments in plants that have been linked to beneficial effects against chronic diseases, such as cardiovascular diseases, type 2 diabetes and neurodegenerative diseases. However, anthocyanins as well as other polyphenolic compounds are often sensitive to degradation during processing, storage and digestion. LÄS MER
4. Mobile phosphorus in lake sediments, sludge and soil : A catchment perspective
Sammanfattning : Phosphorus (P), a key element in lake primary production and eutrophication, is accumulating in agricultural soil, urban landfills and lake sediments. This accumulation increases the risk for non-point losses of P to ground- and surface waters. LÄS MER
5. Sample preparation and mass spectrometry in proteome studies
Sammanfattning : Proteome studies aim to link gene to function. Instead of screening for function in a specific protein as in classical protein chemistry, proteins are now screened against a specific phenotype, disease or metabolic state. LÄS MER
