This thesis presents the prototype of a search for new phenomena that decay in two jets, in presence of an associated jet (three-jet or trijet final state). Mass combination studies are carried out to reconstruct dijet resonances in different mass regions. The two models of interest are the composite quark, which contains a composite quark resonance Q, and the simplified dark matter mediator mod
The aim of this Master's Thesis was to develop a standard for structural testing of implants to be used in transfemoral osseointegrated prostheses, since there is a lack of such standards for this type of implant. The methods used in this project include a literature study, a review of ISO standards, simulations of gait in a software called OpenSim, and a comparison of the OpenSim results with
The degree project described in this report also acts as a deliverable for a research project. The research project focuses on a new technique for the upgrading of biogas. This new technology uses a sterically hindered amine to absorb carbon dioxide from the biogas to raise its energy value. The amine used for this method is 2-amino-2-methyl-1-propanol or AMP. When absorb-ing carbon dioxide with t
Digitalization is changing the conventional face of business, posing ethical questions with regards to how businesses create, collect, use, and store data as part of their everyday business activities. Moreover, because of the pervasiveness of data technologies and unpredictability of their effects on society at large, the complex network of stakeholders affected by data handling is increasing exp
This thesis started with a desire to delve into the impact that natural disasters have on small communities in an Australian context, how climate change exacerbates their effect, and the role that design can play in mitigating the impact on people and the natural environment. Initial research into bushfires, drought, floods, and heat landed this project in Western Sydney, in an area not far from w
The purpose of this study was to evaluate lesion conspicuity achieved with five different iterative reconstruction techniques from four CT vendors at three different dose levels. Comparisons were made of iterative algorithm and filtered back projection (FBP) among and within systems. An anthropomorphic liver phantom was examined with four CT systems, each from a different vendor. CTDIvol levels of
Quinones are essential components in most cell and organelle bioenergetic processes both for direct electron and/or proton transfer reactions but also as means to regulate various bioenergetic processes by sensing cell redox states. To understand how quinones interact with proteins, it is important to have tools for identifying and characterizing quinone binding sites. In this work three different
Glycan utilization plays a key role in modulating the composition of the gut microbiota, but molecular insight into oligosaccharide uptake by this microbial community is lacking. Arabinoxylo-oligosaccharides (AXOS) are abundant in the diet, and are selectively fermented by probiotic bifidobacteria in the colon. Here we show how selectivity for AXOS uptake is established by the probiotic strain Bif
The anaesthetic conserving device AnaConDa(®) (ACD) reflects exhaled anaesthetic agents thereby facilitating the use of inhaled anaesthetic agents outside operating theatres. Expired CO2 is, however, also reflected causing a dead space effect in excess of the ACD internal volume. CO2 reflection from the ACD is attenuated by humidity. This study tests the hypothesis that sevoflurane further attenua
Human recognition of the actions of other humans is very efficient and is based on patterns of movements. Our theoretical starting point is that the dynamics of the joint movements is important to action categorization. On the basis of this theory, we present a novel action recognition system that employs a hierarchy of Self-Organizing Maps together with a custom supervised neural network that lea
We update the forcings for the PMIP3 experiments for the Last Millennium to include new assessments of historical land use changes and discuss new suggestions for calibrating solar activity proxies to total solar irradiance.
A reduced finite element model for determining the maximum principal stress of a glass pane subjected to dynamic impact load is developed and compared to a full dynamic finite element model. The reduced model is based on the Rayleigh-Ritz method. The Ritz vectors used are determined by simple static load-cases. The model is applicable to centrically and eccentrically applied impact and to glass of
C1q is the initiator of the classical complement pathway and opsonizes apoptotic cells to facilitate phagocytosis. Deficiency of C1q is the strongest known risk factor for development of systemic lupus erythematosus (SLE)a, which appears to be related to ensuing impaired clearance of apoptotic material. The objective of the current study was to investigate new ligands for C1q on the surface of apo
Studying how animals interface with a virtual reality can further our understanding of how attention, learning and memory, sensory processing, and navigation are handled by the brain, at both the neurophysiological and behavioural levels. To this end, we have developed a novel vision-based tracking system, FicTrac (Fictive path Tracking software), for estimating the path an animal makes whilst rot
Acquired hemophilia A (AHA) is an autoimmune disease caused by an autoantibody to factor VIII. Patients are at risk of severe and fatal hemorrhage until the inhibitor is eradicated, and guidelines recommend immunosuppression as soon as the diagnosis has been made. The optimal immunosuppressive regimen is unclear; therefore, data from 331 patients entered into the prospective EACH2 registry were an
Abstract in UndeterminedPurpose - The purpose of this paper is to describe and analyse ways of organizing integrated care for older persons in Sweden during the past decade. Design/methodology/approach - The data consist of 62 cases of development work, described in official reports. A meta-analysis of cases was performed, including content analysis of each case. A theoretical framework comprising
Objectives To compare different chronic obstructive pulmonary disease (COPD) cost-effectiveness models with respect to structure and input parameters and to cross-validate the models by running the same hypothetical treatment scenarios. Methods COPD modeling groups simulated four hypothetical interventions with their model and compared the results with a reference scenario of no intervention. T
Det finns idag nationella målsättningar om att öka andelen resor som genomförs med cykel och arbetet sker bland annat genom förbättrad infrastruktur. En del av infrastrukturen som idag anses vara bristfällig är cykelparkering vid bostaden, vilket somliga kommuner börjat reglera genom att ställa krav vid nybyggnation. Men trots att arbetet med frågan blir vanligare finns bristfällig kunskap kring bThere are national goals in Sweden for increasing the proportion of trips made by bicycle. Many believe that this partly can be achieved by improving bicycle infrastructure and recently parking facilities have been gaining more attention in bicycle planning. Most bicycle trips start or end at home and this is also the location where many bikes are parked a majority of the time. However, there is a
Japanese knotweed, Reynoutria japonica, is a highly invasive alien species which has spread in Europe and America since it was introduced in the middle of 1800. Its ability to outcompete and suppress native plants and combined with its resilience and regenerative properties makes it difficult to control. Therefore, multiple methods have been tried to control this plant, but with varying success. T
