Uncovering symmetries in polynomial systems

In this paper we study symmetries in polynomial equation systems and how they can be integrated into the action matrix method. The main contribution is a generalization of the partial p-fold symmetry and we provide new theoretical insights as to why these methods work. We show several examples of how to use this symmetry to construct more compact polynomial solvers. As a second contribution we pre

Health care utilisation among older persons with intellectual disability and dementia : a registry study

BACKGROUND: Both persons with intellectual disability (ID) and persons with dementia have high disease burdens, and consequently also high health care needs. As life expectancy increases for persons with ID, the group of persons with the dual diagnosis of ID and dementia will become larger.METHOD: Through national registries, we identified 7936 persons who had received support directed to persons

Burkitt lymphoma and diffuse large B-cell lymphoma – therapeutic strategies and pathogenetic mechanisms

Burkitt lymphoma (BL) is a rare, aggressive disorder constituting 1% of all non-Hodgkin lymphoma. Diffuse large B-cell lymphoma (DLBCL) is more common, accounting for 30% of malignant lymphoma. Standard treatment for adult BL and for certain subgroups of patients with DLBCL remains to be defined due to paucity of randomised trials performed. The focus in this thesis lies on the effect of prognosti

Renovation of Swedish Single-family Houses to Passive House Standard : Analyses of Energy Savings Potential

A third of Sweden's two million single-family houses were built in the period 1961-1980, and many of them are in need of renovation. These houses have a high energy use and are in technical terms fairly homogenous. This investigation evaluates the theoretical energy savings potential of renovating houses from this period. Four reference houses were selected and simulated using common renovation me

Catalytic Formation of Disulfide Bonds in Peptides by Molecularly Imprinted Microgels at Oil/Water Interfaces

This work describes the preparation and investigation of molecularly imprinted polymer (MIP) microgels (MGs) stabilized Pickering emulsions (PE) for their ability to catalyze the formation of disulfide bonds in peptides at the O/W interface. The MIP MGs were synthesized via precipitation polymerization and a programmed initiator change strategy. The MIP MGs were characterized using DLS analysis, S

Hypothalamic and Metabolic Dysfunction in Genetic Models of Huntington’s Disease

Huntington’s disease (HD) is caused by a CAG trinucleotide repeat expansion in the huntingtin (HTT) gene. HD is an inherited progressive neurodegenerative disorder manifested by the wide array of motor dysfunctions, as well as non-motor symptoms. The latter include metabolic dysfunction and psychiatric deficits, such as depression and anxiety, are often observed in patients andanimal models of HD

Prognostic impact of tumour-infiltrating B cells and plasma cells in colorectal cancer

Multiple studies have described associations between infiltrating immune cells and prognosis in cancer; however, the clinical relevance has most often been attributed to the T-cell linage. This study aimed to further investigate the clinicopathological correlates and prognostic impact of B cell and plasma cell infiltration in CRC. Immunohistochemical expression of CD20, CD138 and immunoglobulin ka

Gender, anthropometric factors and risk of colorectal cancer with particular reference to tumour location and TNM stage : A cohort study

Background: It remains unclear whether the increased risk of colorectal cancer (CRC) associated with obesity differs by gender, distribution of fat, tumour location and clinical (TNM) stage. The primary aim of this study was to examine these associations in 584 incident colorectal cancer cases from a Swedish prospective population-based cohort including 28098 men and women. Methods: Seven anthropo

Divine Suspense : On Kierkegaard's Frygt og Bæven and the Aesthetics of Suspense

What does it mean to feel suspense? What kinds of situations give rise to the emotion? What is the connection between suspense and narrativity? And how is it that we can feel suspense upon repeat encounters with the same narrative? These questions are at the center of the first part of this study, where I develop and defend the ‘imminence theory of suspense’. Central to this theory is the claim th

On the Problem of Finding Optimal Harmonic Periods

Harmonic periods have wide applicability in industrial real-time systems. Rate monotonic (RM) is able to schedule task sets with harmonic periods up to 100% utilization. Also, if there is no release jitter and execution time variation, RM and EDF generate the same schedule for each instance of a task. This property decreases the jitters which happen during sampling and actuation of the tasks, and

Protecting Ecological Integrity in Transboundary Watercourses : An Integrational Approach towards Implementing Environmental Flows

The thesis explores the obligation in international law to protect the ecological integrity of transboundary watercourses. The thesis specifically examines the obligation to protect environmental flows, which essentially means to protect a certain water flow for the benefit of freshwater ecosystems and the ecosystem services they supply.

Identifying root causes of inefficiencies in road haulage: case studies from Sweden, Switzerland and Germany

Road haulage operations in general, and distribution in particular, are inefficient. Given the societal importance of road haulage and the low efficiency of the sector, road hauliers need to improve their operations and systematically tackle inefficiencies. However, the real causes of these inefficiencies, the “root causes”, have not been sufficiently examined in previous studies.

HITS/Transparens Slutrapport

Projektet HITS/Transparens utforskar hur frivillig användning av informations- och kommunikationsteknologi av privata aktörer kan förbättra informationstransparens i transport av farligt gods. Detta tillvägagångssätt skiljer sig från en lång rad projekt som sedan 80-talet haft ett centralt myndighetsperspektiv på informationshantering kring farligt gods. I linje med tidigare resultat inom forsknin

Niche separation of pollen beetle parasitoids

Species with similar resource requirements are commonly assumed to competitively exclude each other, unless they differentiate their ecological niches. Hence, parasitoid wasps that use the same host species need to find some way to avoid competition. The aim of this study was to identify the role of volatile cues from oilseed rape plants and the larval host in niche separation between three coexis

Amphibian conservation in Central Menabe

The amphibian fauna of the Central Menabe region in Western Madagascar is important in respect to their extraordinary adaptations to the dry forest habitat. This habitat is highly threatened. Until 1990, the dry forest in the west of the island was thought to have been reduced to only 3% of its original extent. New analyses show that this deforestation was ongoing at an alarming rate also in the l

Continuum modeling of the coupled transport of mass, energy, and momentum in paperboard.

This thesis investigates the coupling between moisture, heat, and deformation in paperboard. The presented investigations are primarily conducted via macroscale continuum modeling but experimental characterisations are also made. The continuum modeling is presented in a mixture theory framework where the paperboard is considered as a porous media composed of three immiscible phases; a network of c
