The objective of the work described in this thesis is to identify the principles and parts of an aftertreatment system for the catalytic NOx reduction for heavy-duty diesel vehicles, and to demonstrate such a system in full-scale. The reducing agent is diesel fuel. Many advantageous features of the diesel engine, such as life span, reliability and efficiency, make the engine the most frequent pow
The work in this thesis concerns polymer gels, especially their swelling and mechanical properties modelled using a coarse-grained model of polyelectrolytes. The method used to study polymer gels was molecular simulation utilising the simulation package MOLSIM. Particular focus is on the effect of salt, macroions and network topology effects (polydispersity, loose-ends and interpenetrating network
Temperature-dependent structure and function of group A streptococcal M proteins.This thesis describes the temperature-dependent structure of the members in the group A streptococcal M protein family. M proteins are cell-surface proteins that are important for the bacterial virulence and bind to a diverse set of human plasma proteins. The proteins are dimeric coiled-coil molecules, but temperature
Just as all other organisms, plants adapt to various environmental conditions. This work focuses on the role of chloroplast light harvesting complex II, LHCII, in adaptation of photosynthesis to changed light conditions. The two photosystems of oxygenic photosynthesis, photosystem I and II, use light of slightly different wavelengths for photochemistry. Since the photosystems are coupled in serie
The present study deals with the works of John Rufus, disciple of Peter the Iberian at Gaza. There are three works preserved from him, composed in Greek at the turn of the sixth century, and preserved in Syriac: the Life of Peter the Iberian, the Commemoration of the Death of Theodosius, and the Plerophories. This study reads the hagiographic works of John Rufus in search for the basic ideological
Most terrestrial vertebrates have colour vision, some perceive a less colourful world and others actually discriminate a wider colour spectrum than humans do. Still, we can all make use of the valuable colour information, which is more rigid than just brightness. However, at night when the light is dim, the lack of photons makes colour vision difficult. Nevertheless, some hawkmoths and bees can se
CD40 is a cell surface receptor of pivotal importance that is expressed on several of the cells in the immune system. It is critical for many important events, such as T cell dependent B cell activation, isotype switching, somatic mutation and generation of B cell memory. The central role of CD40 in the immune system makes it an ideal target for antibody based immunotherapy. This led us to charact
L-DOPA pharmacotherapy in Parkinson’s disease (PD) is associated with adverse effects occurring after a few years of treatment. Among these, dyskinesia (abnormal involuntary movements) is particularly common and potentially disabling. The causes behind dyskinesia are not completely understood, but intense research has identified a number of neuronal alterations associated with L-DOPA-induced dyski
Sum rules and physical limitations within electromagnetic theory and antenna theory have received significant attention in the last few years. However, the derivations are often relying on application specific and sometimes unsupported assumptions, and therefore a mathematically rigorous and generally applicable approach seems timely. Such an approach is presented in this thesis, along with exampl
The main aim of the research is to explore different aspects of organisational resilience in escalating situations, with an investigation of both theoretical and practical implications. From the platform of an explorative approach, this study makes use of naturalistic research in the domain of health care and experimental simulation studies, in order to establish a broad theoretical framework vis-
The last proportion of heredity in breast cancer has proven to be somewhat elusive despite massive attempts to identify the associated factors. Approximately 50 percent of breast cancer caused by familial factors is currently explained. The five-year survival for breast cancer patients is excellent; however, breast cancer is considered a chronic disease, and given enough time, new tumors can devel
The purpose of this thesis was to increase the understanding of altered movement patterns in individuals with anterior cruciate ligament (ACL) injury in order to improve ACL rehabilitation, and to develop an observational instrument termed Test for Substitution Patterns (TSP) for standardized, quantifiable scoring of altered movement patterns in legs and trunk. In all, 142 participants, 93 with A
More and more companies are adopting Circular Business Models (CBMs), which can serve to foster a sustainable transition towards a Circular Economy (CE). Nonetheless, much of the CBMs adoption-related research in academia has a focus on end-user facing companies, which have direct access to final end-users, to whom they sell a complete product. However, a significant role in such settings is playe
Extant research within the entrepreneurial marketing field has typically focused on the migration away from traditional marketing concepts while mostly ignoring the inclusion of branding as a fundamental principle of marketing. This paper is specifically interested in the often overlooked element of a young firm’s ability (or lack thereof) to control its brand and brand identity as perceived by it
Introduction: Dental caries among preschool children is a global problem, a burden on children’s well-being, and an economic burden on healthcare systems. In Sweden, preschool children with an immigrant background have a higher prevalence of caries. Extensive treatment need and long-standing poor oral health may require dental treatment within hospital care. This study aimed to investigate whether
The external ventricular drain (EVD) is an important instrument in the management of neuro-intensive care patients through its ability to meassure intracranial pressure and to treat increased intracranial pressure by drainage of cerebrospinal fluid (CSF). However, EVDs are associated with the risk of external ventricular drain related infection (EVDRI). EVDRI diagnosis is challenging as symtoms an
