The purpose of this project was to gain knowledge of polyhydroxyalkanoates’ (PHAs’) ability to be fractionated and form miscible blends for different structures, by using the methods: solvent/non solvent fractionation and co-dissolving in 2-butanol.The outcome of the fractions and blends was evaluated with differential scanning calorimetry (DSC), size exclusion chromatography (SEC), Fourier transf
This bachelor thesis was performed at BorgWarner AB in Landskrona. The assignment was to investigate different methods for external measurement of a permanent magnetized DC motor speed in revolutions per minute when you have no access to the rotor. The task was to examine different measurement methods, to produce a finished circuit that converts the signal frequency to rpm and build a complete too
Building new wind farms is an important part in the transition to renewable energy. However these projects often require large investments, and the cost of upgrading the existing infrastructure - to allow for the connection of new parks - is a component that cannot be ignored. When several wind farms seek interconnections, they are forced to collaborate and financing the connection. This leads to
After the introduction of a conjugate vaccine that provides immunization to Haemophilus influenzae type b, an increase in the number of infections caused by Non-typeable H. influenzae (NTHi) has been reported. NTHi mostly affects children under the age of 1, causing cases of otitis media and conjunctivitis, and it is also associated with respiratory tract infections such as exacerbations of chroni
The CRISPR-Cas9 system for genetic engineering has recently emerged as promising tool for studying gene functions in a variety of systems and organisms. Here, we are particularly interested in studying the role of DGCR8 in a human neuroepithelial-like stem (hNES) cell line. Beyond its characterized role in the microRNA biogenesis pathway, recent studies have implicated the enzyme’s involvement in
Objective: Citrate is widely used in dialysis, either as an acid in dialysis fluids or as a regional anticoagulant. In both cases, the concentration of citrate in the plasma of the patients will increase above physiological levels, up to 5-foldes in some cases. The aim of this study was to investigate the effect of citrate on the transcriptional level, as well as on the metabolic level and elucida
The focus of this master’s thesis has been getting a six-legged robot to autonomously navigate around a room with obstacles. To make this possible a time-of-flight camera has been implemented in order to map the environment. Two force sensing resistors were also mounted on the front legs to sense if the legs are in contact with the ground. The information from the sensors together with a path plan
Marine protected areas (MPA) have been widely used the recent years, as an alternative to the traditional management tools, in order to increase the yield and the health of a stock. The present study shows how cod population in Öresund would respond under different spatial and temporal MPA and how they will affect the gill-net fisheries in the area. For that reason, a simple model, based on logist
Sanddyner är landformer som bildas av vinden. Deras inre uppbyggnad utgörs av korslagringar och begränsningsytor som kan ge väsentlig information om det lokala klimatet och miljön vid dynernas bildning. Georadarundersökning som är en snabb, enkel och ickedestruktiv reflektionsmetod, ger en god bild av sanddynernas inre struktur eftersom korslagringar och begränsningsytor ger upphov till reflektoreDunes are landforms formed by the wind. Their internal architecture consists of cross beds and bounding surfaces that provide important information about the local climate and environment during dune formation. GPR is a quick, easy and non-destructive reflection method that provides an illustration of the dunes’ inner structure because crossbeds and bounding surfaces gives rise to re-flections tha
Does economic globalization impact sexual beliefs, contributing to the rise of right-wing parties? Although voters may not discern threats from trade shocks, individual economic insecurity theoretically impacts cultural attitudes and sparks a backlash towards outgroups, in turn contributing to right-wing candidates that campaign leveraging intolerance. Considering that scholars provide evidence fo
In the past decade, micro-enterprise development has gained popularity as an intervention in the Global South, including Colombia, a country where more than 90% of businesses are micro. For decades, this country has endured an internal conflict that has left millions of victims of forced displacement, who live in vulnerable situations and, in many cases, resort to creating micro-enterprises to mak
Despite prayer being one of the most central tenets of Islam, this subject has drawn the attention of surprisingly little scholarship, especially when it comes to studying its origin against pre-Islamic analogues. Thus, this thesis proposes a reconstruction of the very early history of the fivefold daily Islamic liturgy, attempting also to weigh the extent of the influence that pre-Islamic religio
The purpose of this paper is to speak on the similarities and differences between the Traverso and the Boehm-flute, specifically on interpretation and focusing on the embouchure, sound colour, and tuning systems. The written format of this study allowed me to express better and be more specific on the information selected to be more concise and beneficial to what I intended from this research. As
This thesis focuses on the development of financialisation and financialisation of everyday life in Sweden during the 1980s and 1990s. These years were turbulent for the Swedish economy and contains the so called turn to the market. This thesis uses the reports of NIER to analyse and describe the financialisation of everyday life and the genera l financial history of Sweden at the time. The NIER r
Denna studie syftar till att undersöka sambandet mellan hög mobiltelefonanvändning och allmänt mående bland gymnasieelever. Med stöd från två välgrundade teorier: självregleringsteorin och sociala inlärningsteorin, har studien presenterat intressanta korrelationer och samband kring mobilanvändning och allmänt mående. Studien är uppdelad i två olika studier, en kvantitativ och en kvalitativ. KvantiThis study aims to investigate the relationship between high mobile phone use and general well being among high school students. With support from two well-founded theories: the self-regulation theory and the social learning theory, the study has presented interesting correlations and connections around mobile phone use and general ill-health. The study is divided into two studies, one quantitativ
Denna kandidatuppsats fokuserar på införandet av AI inom e-handel i Sverige. En kvalitativ metod antogs genom att intervjua yrkesverksamma som arbetar inom e-handelssektorn. Resultaten presenterades med hjälp av TOE-ramverket. Denna studie syftar till att få insikter i hur e-handelsföretag använder AI-teknik och vilka utmaningar de stöter på. Därmed bidrar denna avhandling till forskningen genom aThis thesis focuses on the adoption of AI within e-commerce in Sweden.
