36. Diffusion of Water in Foods during Heating
Sammanfattning : The overall aim of this research was to improve the knowledge of diffusion of water in foods during heating, so that the final quality of foods after heat processing could be predicted and controlled. The work consisted of three main parts. The first part involved the development of a method to study the diffusion. LÄS MER
37. Secondary Emissions from Concrete Floors with Bonded Flooring Materials - Effects of Alkaline Hydrolysis and Stored Decomposition Products
Sammanfattning : It has been demonstrated before that the presence of VOC lowers the quality of indoor air. There are also several indications that certain organic compounds in indoor air (OCIA) can give rise to sick building syndrome (SBS). LÄS MER
38. Theoretical Modeling and Near-Infrared Spectroscopy Monitoring of Vial Lyophilization
Sammanfattning : The research documented in this thesis was directed towards lyophilization of pharmaceuticals in vials (vial lyophilization) and it was focused on the design and control of this process. Theoretical modeling has considerable potential to guide experimental studies, thereby decreasing development time and improving the possibilities to achieve an optimal and robust process design.

39. Dielectric Response and Partial Discharge Diagnostics of Insulation Systems by Utilizing High Voltage Impulses
Sammanfattning : In this thesis, power system transients are considered as an opportunity for development of on-line diagnostics of power components and specifically the insulation systems of power transformers and bushings.A new technique for on-line dielectric response measurement of power transformer bushings is proposed which utilizes natural transients in the power system, such as lightning and switching surges, as stimuli.
