This master's thesis is a study on the gender system of the Swedish dialect spoken in Jämtland, a province in northern Sweden. The Jämtlandic dialect preserves to a large extent the three-gender system that was present in Old Swedish, in which nouns can be either masculine, feminine or neuter. The three-gender system manifests in anaphoric pronouns and as agreement in the noun phrase. However,
In order to apply combustion feedback control in diesel engines to control pollution formation, good models are needed to estimate the states. One of those would be NOx levels which are regulated by European law. There are conventional sensors on the market that can measure NOx but these are too slow for in-cycle feedback control. The purpose of this thesis was to derive a model to estimate NOx wh
The aim of this explorative study is to gain knowledge about the question of identities formations in different socio-cultural contexts. This is done by looking at the specific case of the Oromo people living in a larger community (Minneapolis, USA) as compared to living in a smaller group (Stockholm, Sweden). The case of the Oromo people is investigated in light of past historical, political, soc
This study focused on expression, purification and functional characterization of three key proteins (Urc1p, Urc2p and Urc8p) in the newly discovered uracil catabolism (URC) pathway. A novel expression system was established by using Saccharomyces kluyveri as a host organism for expression of 6-His tagged Urc1p and Urc2p. Moreover, URC8 gene was cloned in pET151/D-TOPO vector and expressed in Esch
The concept of “undertaking” is a vital component of European Union Competition Law. Understanding when an entity is or isn't considered an undertaking is crucial to correctly applying the rules under this domain. The purpose of this paper is to clarify the concept of undertakings to delimit the area of competition law from others. The paper will explore the different definitions of “unde
Oats (Avena sativa) are part of the cereal whole grain family, and their production is on the rise for the past few years due to extensive research done on the health benefits it can provide to humans. ScanOats project in Sweden is one of the research groups across the world that has done extensive work on oats. The lines CT-BG-53, CT-BG-21, and CT-BG-37 are mutant lines harvested by Crop Tailor A
Inter-frequency measurements are needed to determine when user equipment should make a handover to the best available base station in a cellular mobile network. The measurements are expensive from a resource point of view and therefore there is a need for optimization of this kind of measurements. In this work both this optimization and a way to predict the future of the measurements have been eva
Coronary heart diseases is one of the biggest health problems in the world today. By segmenting the coronary arteries in medical images and examining them, important information about abnormal narrowing and plaque, which are main causes to these diseases, can be found. Manual segmentation of the coronary arteries are time consuming and dependent on the observer, which makes the need of automatic s
Chronic Lyme disease in Germany, although widely discussed in the political sphere, is not yet a legitimate illness in front of the law. Despite being classified as a (re) emerging threat to public health,fragmented regulatory approaches and the isolated nature of knowledge on Borrelia and co-infections represent major obstacles on curbing its growing impact on people's health. This explorativ
One of the overall main purposes for a structural engineer is to design structures and structural elements so that they meet society’s safety requirements, yet use as little material as possible. In order to do so, the designer has to understand and simplify a complex reality. The strut-and-tie method is such a simplification model which allows engineers to design reinforced concrete structures wh
This report focuses on the issues associated with large occupant loads and counter-flows in underground metro stations. A basic case study is performed by simulating different countermeasures scenarios to investigate the implication that the countermeasures may have on the occupant load on the platform. The countermeasures investigated were modifications to the flow through ticket gates or escalat
To combat the ongoing climate change, a sustainable energy system is essential. In recognition of this, Sweden has set a national goal of 100% renewable energy by the year 2040. However, to reach this goal, it is important that efficient tools are utilized. The EU suggests that energy communities can act as one such tool. While research has shown that energy communities can entail several opportun
Dagens bil- och lastbilsindustri upplevs ha komplexa produktionssystem med relativt höga tillverkningskostnader, varav en stor del kan kopplas till arbetskostnader vars arbetsmoment utgörs av komplexa och icke ergonomiska monteringsuppgifter. Genom att automatisera sådana uppgifter kan produktiviteten öka samtidigt som arbetskostnader och sjukfrånvaro minskar. Många produkter och monteringsoperatiToday's car and truck industries are perceived as having complex production systems and relatively high manufacturing expenses, such as labour cost, which is usually combined with complex and unergonomic assembling tasks. A shift towards automation is one solution to eliminate such tasks while increasing productivity and lowering labour costs. Many products and assembly operations are designe
In this thesis, it is analysed if cardiac arrest patients can be grouped into similar clusters based on different underlying conditions and clinical variables and if there is a difference between clusters in either mortality or neurological outcome as measured by the Cerebral Performance Categories (CPC) scale. The two data sets both contain a targeted temperature management variable which indicat
An adaptive memory system has to support both the encoding of individual episodes as well as generalization and inference across several episodes. The latter of these two goals is achieved by memory integration in which a memory representation is updated to accommodate new information. However, the circumstances leading to either separate encoding or generalization are still unknown. Building on l
The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. In contrast to more conventional n-type material system, however, p-type quantum devices benefit from
To simulate district heating networks, in this project the simulation environment Dymola was used. The goal was to run simulation of district heating network and at the same time have good network representation to easily change between different models and also change between doing simulation and optimization. Different models had to be created in Dymola and tested to ensure they work accordingly
Textile fibres made from cellulose is a plausible candidate for replacing cotton in the future. In order to create textile fibres from cellulose the cellulose must first be dissolved and proceeded by regeneration through spinning. In this study mainly the solubility of regenerated cellulose has been investigated. Micro crystalline cellulose (MCC) was regenerated by dissolving it in NaOH (2 M) and
