31. Optical properties of novel semiconductor nanostructures
Sammanfattning : Semiconductor nanostructures, such as one-dimensional nanowires (NWs) and zerodimensional quantum dots (QDs), have recently gained increasing interest due to their unique physical properties that are found attractive for a wide variety of applications ranging from gas sensing and spintronics to optoelectronics and photonics. Here, especially promising are nanostructures based on compound semiconductors, including ZnO, GaNP and GaAs/InAs. LÄS MER
32. Exploring novel roles of tumor pericytes
Sammanfattning : Tumor biology has been extensively studied over the last few decades, with a principal focus on how neoplastic cells obtain cellular immortality. A number of oncogenes and tumor suppressor genes have been uncovered that regulate cancerous transformation. LÄS MER
33. Towards a broader use of phototesting : in research, clinical practice and skin cancer prevention
Sammanfattning : In western societies, skin cancer incidence has increased dramatically over recent decades, due predominantly to increased sun exposure habits. Ultraviolet (UV) light exposure and individual light sensitivity of the skin constitute two important factors affecting the risk for skin cancer development. LÄS MER
34. Novel Hessian approximations in optimization algorithms
Sammanfattning : There are several benefits of taking the Hessian of the objective function into account when designing optimization algorithms. Compared to using strictly gradient-based algorithms, Hessian-based algorithms usually require fewer iterations to converge. LÄS MER
35. Novel functions of cardiovascular P2 receptors
Sammanfattning : The aim of the thesis was to examine the expression and function of the extracellular nucleotide P2 receptors in the cardiovascular system. In the cardiovascular system nucleotides are released during shear stress, hypoxia, ischemia, from endothelial cells, smooth muscle cells, aggregating platelets, inflammatory cells and erythrocytes.
