1. Ductile damage modeling of the machining process
Sammanfattning : Machining processes are among the most common manufacturing processes for producing components used on a daily basis. It is a complex material removal process. Today, the research and development within the manufacturing industry is addressed by cost efficient numerical simulation strategies rather than by costly experimental procedures. LÄS MER
2. Radiation response in human cells : DNA damage formation, repair and signaling
Sammanfattning : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. LÄS MER
3. Biomarkers for DNA damage in human biomonitoring
Sammanfattning : Genomic DNA in humans is constantly exposed to different kinds of damage. Therefore, it is desirable to implement methods for detecting and measuring of inflicted body burden. Human biomonitoring (HBM) can here be a useful tool as a link between environmental exposure and disease outcome. LÄS MER
4. Human mononuclear phagocytes : Production of reactive oxygen species generated by the NADPH oxidase
Sammanfattning : Human professional phagocytes constitute the first line of defence against invading microorganisms. With a membrane-bound enzyme system, the NADPH oxidase, these cells generate bactericidal metabolites. Activation of NADPH oxidase results in a generation of reactive oxygen species, e.g. LÄS MER
5. Context dependent adaptation of biting behavior in human
Sammanfattning : The focus of this thesis was to study an action that humans perform regularly, namely, to hold a morsel between the teeth and split it into smaller pieces. Three different issues related to this biting behavior were addressed: (1) the effect of reduced periodontal tissues on food holding and splitting behavior; (2) the behavioral consequences of performing different bite tasks with different functional requirements, i.
