Abstract Background: Caring for tracheostomized patients in the intensive care unit is a common practice, and there are many advantages to having an endotracheal tube. It is for example easier to wean from a ventilator, facilitates oral hygiene and intake, and leads to earlier use of speaking valves while still needing respiratory assistance. Specialist nurses are invaluable in terms of patient

Metalloenzymes are proteins that contain one or more metal ions bound to protein. They constitute about one-third of all enzymes known so far and they often perform hard chemical reactions involving small substrates, like H2 and N2. In our research, we focus on those metal ions that are located in the active sites and perform redox reactions, i.e. involving electron transfer. Why enzymes?Metalloenzymes catalyse a wide variety of reactions in nature. In the thesis, I have studied the reaction mechanism of three metalloenzymes, viz. [NiFe] hydrogenase (H2ase), dimethyl sulfoxide reductase (DMSOR) and formate dehydrogenase (FDH), by theoretical methods, namely quantum mechanics (QM), combined quantum mechanical and molecular mechanics (QM/MM), as well as QM/MM thermodynamic cycle per

This thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC. The intial state of the incoming particles are simulated by colour dipoles in transverse space evolved through rapidity. With this approach, all fluctuations are dynamically described, allowi

The central question addressed in this thesis is how to make the free-electron laser (FEL) more efficient. In recent years, coherent diffraction imaging provides an important motivation for efficiency enhancement. This is because a more efficient FEL process enables converting a larger fraction of the electron beam's power into optical power. By increasing the average optical power to the terawatt

Delegating tasks from a human to a robot needs an efficient and easy-to-use communication pipeline between them - especially when inexperienced users are involved. This work presents a robotic system that is able to bridge this communication gap by exploiting 3D sensing for gesture recognition and real-time object segmentation. We visually extract an unknown object indicated by a human through a p

Popular Abstract in English Foods, microorganisms, and humans have been tightly associated from the start of human history. Foods are not only the source of nutrients for humans, but also good media for microorganisms. Although we humans discovered the existence of microorganisms relatively recently, we have been dealing with them for hundreds and thousands of years. We have used some microorganisStaphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. The differences in the amounts of SEA formed were found to be associated with the levels of expression of the sea gene and the bacteriophage version

Climate change has led to an increase in heavy summer rainfalls, and climate projections for Sweden indicate that there will be more sudden rainfall in the future. While the exact locations and time for this rainfall are unknown, it is known that there will be damages to buildings, cars, and people when the rainfall occurs. It is thus important to evaluate past events to understand the resulting f

Background/Aims: Peptide receptor radionuclide therapy (PRRT) is becoming clinical routine for management of neuroendocrine tumours. The number of PRRT cycles is correlated with treatment effect but theoretically limited by off-target radiation damage to kidneys and bone marrow. New imaging biomarkers for assessment of PRRT tissue damage would enable evaluation of novel renal and bone marrow prote

Purpose Complex organizations increasingly rely on middle managers as strategic linking-pins between the top and bottom levels of the organization. Using social identity theory and commitment theory as the foundation, this study evaluates a management and leadership development program (MLDP) intended to engage middle managers as strategy creators and implementers. We also evaluate the cascading e
