16. In silico tools in risk assessment : of industrial chemicals in general and non-dioxin-like PCBs in particular
Sammanfattning : Industrial chemicals in European Union produced or imported in volumes above 1 tonne annually, necessitate a registration within REACH. A common problem, concerning these chemicals, is deficient information and lack of data for assessing the hazards posed to human health and the environment. LÄS MER
17. Practical application of machine learning for analyses of biological matrices and environmental phenomena
Sammanfattning : This thesis presents research aimed at forwarding an understanding of machine learning methods as a method of studying complex matrices and environmental phenomena. A number of machine learning methods in the form of linear projection algorithms and statistical experimental designs were applied for qualitative analysis of different matrices. LÄS MER
18. Signal identification for visual electrophysiological recordings. A comparison of signal analysis techniques and their application to clinical electrophysiology of vision
Sammanfattning : Aims: The aim of this thesis was to investigate the use of objective methods for the analysis of visual electrophysiological recordings. Specifically can signal identification algorithms identify electrophysiological signals and can they be applied to improve clinical testing and analysis? Methods: Automated signal identification algorithms were applied to multifocal electroretinogram (mfERG) and visual evoked potential (VEP) recordings. LÄS MER
19. Characterisation of mammalian cell culture processes with NIR spectroscopy
Sammanfattning : The importance of recombinant proteins produced by mammaliancell culture has increased dramatically due to the discoveriesin the field of recombinant biotechnology. Therefore,optimising and gaining process knowledge about cell culture hasalso gained in interest. LÄS MER
20. Multivariate non-invasive measurements of skin disorders
Sammanfattning : The present thesis proposes new methods for obtaining objective and accurate diagnoses in modern healthcare. Non-invasive techniques have been used to examine or diagnose three different medical conditions, namely neuropathy among diabetics, radiotherapy induced erythema (skin redness) among breast cancer patients and diagnoses of cutaneous malignant melanoma.
