1. Directing Angiogenesis : Cellular Responses to Gradients in vitro
Sammanfattning : Blood vessels are essential for the delivery of nutrients and oxygen to tissues, as well as for the removal of waste products. Patients with tumors, wounds or diabetes all have active angiogenesis, formation and remodeling of blood vessels, a process that is initiated and manipulated by gradients of secreted signaling proteins.

2. Bipolar electrochemistry for high throughput screening applications
Sammanfattning : Bipolar electrochemistry is an interesting concept for high throughput screening techniques due to the ability to induce gradients in a range of materials and their properties, such as composition, particle size, or dopant levels, among many others. One of the key advantages of the method is the ability to test, create or modify materials without the need for a direct electrical connection. LÄS MER
3. Phytoplankton of Baltic environmental gradients : observations on potentially toxic species
Sammanfattning : .... LÄS MER
4. Gradients of time and complexity : understanding how riparian and instream ecosystems recover after stream restoration
Sammanfattning : Why evaluations of the ecological outcomes of stream and river restoration have largely reported inconclusive or negative results has been the subject of much debate over the last decade or more. Understanding the reasons behind the lack of positive results is important for bettering future restoration efforts and setting realistic expectations for restoration outcomes. LÄS MER
5. Static and Dynamic Modelling of the Drying Section of a Paper Machine
Sammanfattning : The paper making process involves chopping of wood, cooking and forming, followed by dewatering in a vacuum section, press section and drying section. Several models for the most important parts of the paper machine drying section are presented in this thesis to describe phenomena at steady state and during state transitions. LÄS MER
