1. Inhibition of phagocyte signaling by the Yersinia virulence protein YopH
Sammanfattning : Yersinia pseudotuberculosis evades the immediate immune defense of a host organism by inhibiting bactericidal functions of phagocytes, including phagocytosis, cytokine release, and the oxidative burst. Consequently, this pathogen can survive and multiply in lymphatic tissues. An ensemble of proteins called Yops are involved in the virulence of Y. LÄS MER
2. Structured management of patients with suspected acute appendicitis
Sammanfattning : Background. Acute appendicitis (“appendicitis”) is one of the most common abdominal surgical emergencies worldwide. In spite of this, the diagnostic pathways are highly variable across countries, between centres and physicians. This has implications for the use of resources, exposure of patients to ionising radiation and patient outcome. LÄS MER
3. Four applications of stochastic processes : Contagious disease, credit risk, gambling and bond portfolios
Sammanfattning : This thesis consists of four papers on applications of stochastic processes. In Paper I we study an open population SIS (Susceptible - Infective - Susceptible) stochastic epidemic model from the time of introduction of the disease, through a possible outbreak and to extinction. The analysis uses coupling arguments and diffusion approximations. LÄS MER
4. Multiobjective optimization in engineering design : applications to fluid power systems
Sammanfattning : This thesis focuses on how to improve design and development of complex engineering systems by employing simulation and optimization techniques. Within the thesis, methods are developed and applied to systems that combine mechanical, hydraulical and electrical subsystems, so-called multi-domain systems. LÄS MER
5. Skälig misstanke
Sammanfattning : This doctoral dissertation studies the legal standard of proof called reasonable suspicion (skälig misstanke). This standard is central for criminal investigations as the majority of state criminal procedural actions (tvångsmedel) are tied to it, as well as the majority of a suspect’s rights. LÄS MER
