11. Regulation of innate and adaptive immune responses by Gram-positive and Gram-negative bacteria
Abstract : Bacteria are classified as Gram-positive or Gram-negative, depending on their cell wall structure. The role of the bacterial cell wall in immune regulation is the focus of the current work. Most Gram-positive bacteria stimulate monocytes to produce large amounts of IL-12. READ MORE

12. On Gate Drivers and Applications of Normally-ON SiC JFETs
Abstract : In this thesis, various issues regarding normally-ON silicon carbide (SiC)Junction Field-Effect Transistors (JFETs) are treated. Silicon carbide powersemiconductor devices are able to operate at higher switching frequencies,higher efficiencies, and higher temperatures compared to silicon counterparts. READ MORE

13. On Reliability of SiC Power Devices in Power Electronics
Abstract : Silicon Carbide (SiC) is a wide-bandgap (WBG) semiconductor materialwhich has several advantages such as higher maximum electric field, lowerON-state resistance, higher switching speeds, and higher maximum allowablejunction operation temperature compared to Silicon (Si). In the 1.2 kV - 1. READ MORE

14. Using social norms in energy conservation interventions
Abstract : When designing interventions to promote pro-environmental behaviors, practitioners may choose between techniques based on for example education, incentives, commitments, or social norms. These intervention techniques may, however, target different kinds of motivation, and therefore differ in their psychological and behavioral implications. READ MORE

15. Hemophagocytic lymphohistiocytosis and associations with malignancies
Abstract : In immune homeostasis, natural killer cells and cytotoxic T cells are responsible for clearance of virus-infected and tumor transformed cells, but also for turning off the immune response. Patients with familial hemophagocytic lymphohistiocytosis (HLH) have impaired cytotoxic function due to genetic aberrations in genes in the perforindependent cytotoxic pathway. READ MORE
