6. Psychotropic Pharmaceuticals in Aquatic Systems: An Ecological Perspective
Sammanfattning : Psychotropic pharmaceuticals have been shown to exert a variety of sublethal effects on non-target organisms, even at low concentrations found in the environment (ng/L to µg/L); hence, the aim of my research has been to determine the individual-level effects of psychotropic pharmaceuticals (the selective serotonin reuptake inhibitors sertraline and fluoxetine, and the β-blocker propranolol) on behavioral and life history traits in freshwater organisms. Further, this research was directed towards assessing the potential large-scale impacts of these effects on population growth and predator-prey interactions (with community-level implications) via the application of traditional, ecological concepts and models.

7. Bioelectronic Nanosensor Devices for Environmental and Biomedical Analysis
Sammanfattning : A new type of Bioelectronic Nanosensor Device with potential applications in medicine,biotechnology and environmental analysis was designed. The nanosensor is based on RISFET (Regional Ion Sensitive Field Effect Transistor) technology. LÄS MER
8. Development and improvement of methods for characterization of HPLC stationary phases
Sammanfattning : High Performance Liquid Chromatography (HPLC) is a widely used tech-nique both for detecting and purifying substances in academy and in the industry. In order to facilitate the use of, and knowledge in HPLC, character-ization of stationary phases is of utmost importance. LÄS MER
9. Effects on cardiac output distribution of propranolol, verapamil and epidural blockade during continuous positive-pressure ventilation : An experimental study in the pig
Sammanfattning : The blood perfusion of all body regions is governed by local vasoregulation, and systemic humoral and neural impulses provide additional tuning of vascular tone. Is the regulation of circulation centralised or, in other words, is the sympathetic nervous system (SNS) superior to local autoregulation of the perfusion of vital organs? Using the microsphere method and acquired data on the body composition of the pig, it was possible to interpret the absolute distribution of cardiac output (CO) and flux changes between organs and tissues.

10. Adrenergic control of small intestinal motility and blood flow : an experimental study in rat and man
Sammanfattning : Small intestinal motility in the fasted state is characterized by migrating motor complexes (MMCs). Both animals and man exhibit the MMC, which consists of periods of regular contractions, i.e. activity fronts, that migrate along the length of the small bowel and alternate with periods of quiescence.
