This research study aims to examine why small business owners comply with rules and regulations within their industries. The purpose is to obtain a deeper understanding of legal obedience amongst small business owners. More specifically, what extrinsic and intrinsic motivations makes small business owners comply with the laws. This study is exploratory and is based on five semi-­structured intervi

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

Do sick birds migrate at different times than healthy ones? The word migration comes from the Latin migratus that means “to change”, referring to how birds change their geographic locations seasonally. Birds migrate to escape from decreased food availability or harsh weather on their breeding grounds. They migrate to areas of high or increasing resources where they stay during the winter period b

Recent advances in high-throughput sequencing have uncovered that the vast majority of the cellular genome encodes for a myriad of noncoding RNAs, which lack coding potential for proteins. Increasing evidence suggests that ncRNA classes are involved in important processes that help in decoding the genetic information within cells. A striking example is the family of small nucleolar RNAs (snoRNAs)

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

Catalase transport in Helicobacter pylori Helicobacter pylori is a bacterium that lives in the human stomach of 50% of the world’s population. Its presence in the stomach induces a strong immune response in all these cases and the body’s response to fight off the infection causes an irritation of the stomach that may be symptomatic or asymptomatic. A persistent infection may lead to ulcers or in

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

What does not kill bacteria, makes them stronger Bacteria most often gather together to form communities called biofilms, which represent the underlying cause of 60% of all infections. Bacteria hidden in the biofilms cannot be eliminated by the human immune system and by antibiotics, therefore, they cause persistent infections which require long-term antibiotic therapy. One of the unwanted effect

Citrat ger cellerna mer energi Njurarna är ett organ i kroppen vars huvuduppgift är att avlägsna överflödig vätska och rena blodet från restprodukter. Njursvikt innebär ett tillstånd där njurarna helt eller till största delen förlorat sin funktion och kan leda till ett livshotande tillstånd då vätskenivån i kroppen ökar. Detta kan bl.a. leda till ett förhöjt blodtryck och att nivån av olika giftiObjective: 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

Current theoretical attempts to understand the reversible formation of stable microtubules and virus shells are generally based on shape-specific building blocks or monomers, where the local curvature of the resulting structure is explicitly built-in via the monomer geometry. Here we demonstrate that even simple ellipsoidal colloids can reversibly self-assemble into regular tubular structures when

This work treats the estimation of the chromagram for harmonic audio signals using a block sparse reconstruction framework. Chroma has been used for decades as a key tool in audio analysis, and is typically formed using a Fourier-based framework that maps the fundamental frequency of a musical tone to its corresponding chroma. Such an approach often leads to problems with tone ambiguity, which we

The effect of temperature on the adiabatic laminar burning velocities of CH4 + air and H-2 + air flames was analyzed. Available measurements were interpreted using correlation S-L = S-LO (T/T-o)(alpha). Particular attention was paid to the variation of the power exponent a with equivalence ratio at fixed ( atmospheric) pressure. Experimental data and proposed empirical expressions for a as a funct

Background: Vietnam introduced the Health Care Fund for the Poor in 2002 to increase access to health care and reduce the financial burden of health expenditure faced by the poor and ethnic minorities. It is often argued that effects of financing reforms take a long time to materialize. This study evaluates the short-term impact of the program to determine if pro-poor financing programs can achiev
