Behovet av mer miljövänliga lösningar har aldrig varit större än idag. Mängden koldioxidutsläpp ökar ständigt, vilket leder till ökad mängd koldioxid i atmosfären. Vid tillverkning av plast används idag vanligtvis olja som råmaterial, men man kan använda biobaserat råmaterial i stället såsom socker. I Sverige produceras socker av sockerbetor. En restprodukt är då melass en tjock sirapsliknande socMolasses is a low value by-product from sugar production that is usually used for animal feed, bioethanol fermentation, and yeast growth substrate. Even though it is a by-product and most of the sugar have been taken out the molasses still contains a fair amount of sugar that can be used for production of HMF, a biobased platform chemical with many areas of application, for example as a feedstock

In recent years, experimental studies on gender assignment to borrowings in languages such as German and Dutch have observed variation in gender assignment in relation to dialectal areas, among other factors. However, many issues related to gender assignment have yet to be fully understood, and the sociolinguistic variation has not been properly investigated. The objective of the present study is

Alfa Laval has a wide product range for plate heat exchangers that can be applied in most industries. The constant development of new and old heat exchangers drive the need for new and efficient methods that can reliably be used in the development process. In this thesis, a new turbulence model within a computational fluid dynamics-program has been tested and evaluated for one of Alfa Lavals comme

This report details a project I undertook with Lument AB, a company developing a new oral contrast agent that patients drink before CT-scans. The new formula has multiple benefits over current contrasts agents on the market for both patients and radiologists, however, it is harder for nurses to prepare. In the project, I research the feasibility of a medical device capable of preparing the contra

In this study a module for calculating the solar exposure of individual fluid cells was developed to more accurately represent the effect of photolysis on the pollutant dispersion in an urban street canyon. The module was tested and validated on 12 different cases, each with a different geographical location, time of year and/or time of day. It was used for four parallel simulations performed on a

Kvantifiering av motoriskt beteende hos råttor i fri rörelse Cirka 10 miljoner människor världen över lever med Parkinsons sjukdom och cirka 40 % av världens befolkning lever med långvarig smärta. Den här avhandlingen handlar om att implementera ett system för att hjälpa till att utvärdera behandlingar för dessa tillstånd, såsom djup hjärnstimulering (DBS). System som används för att förbättra DSystems evaluating potential treatment methods for Parkinson’s disease and chronic pain conditions, using rodent experimental models, are highly needed. Currently used systems are aiming to evaluate these kinds of treatment methods by analyzing the animal’s motor behavior. These systems either generate binary data or multifaceted data for when the rodent is spatially limited or data for when the r

Dystopian fiction first appeared as a literary genre in the 1870s and has since been known to conduct social criticism of the real world in a futuristic, fictive form. As it has evolved during the 20th century it has grown into a widely researched topic. In this essay I will analyze two young adult dystopian novels: Suzanne Collins’ The Hunger Games (2008) and Marie Lu’s Legend (2011). I have chos

It is a well-known fact that in any Application Specific Integrated Circuit (ASIC) design, verification consumes most time and resources. And when it comes to huge designs, finding bugs can be tedious given the area and the complexity. As per Moore’s law, the design complexity is increasing exponentially due to the growing demand for performance. Therefore, On-Chip communication becomes crucial. T

Eigenvalue analysis has been a key tool to science and engineering for several decades. Eigenvalues can predict the behaviour of many mathematical systems of equations but alone they cannot fully explain phenomena such as stability or stiffness. Together, eigenvalues and pseudospectra can give a better understanding of several phenomena such as instability in nonnormal matrices or operators. In th

Studien undersöker om och i sådana fall vilka könsstereotyper som används vid framställning av spelavatarer i League of Legends (LoL). I motsats till tidigare forskning avser uppsatsen att begripa varför detta inträffar. Forskningens resultat tog fram att föreställningar om kön appliceras på kvinnliga och manliga spelavatarer i LoL. Det framgick att spelavatarerna är överdrivna, sexualiserande ochThis thesis investigates if stereotypes and norms are projected in the virtual world. The study specifically aims to understand this through delving into the virtual game League of Legends to inquire if and, in that case, what gender stereotypes are used when constructing gaming avatars. Lastly, our thesis aims to answer and give an explanation for why this occurs. This dissertation is based on t

Online food delivery is becoming increasingly popular and has attracted more and more attention of scholars. However, the study on online food delivery faces a gap of consumer complaints. Those complaints can help service providers improve their service and business. This thesis aims to identify the factors that cause customers to complain and the behaviors customers show when they complain in the

This study explored the possibilities for a safety strategy to contribute to the Safety of the Royal Netherlands Air Force. Nineteen depth interviews and one a focus group comprising of thirteen participants were held. The participants w

Ohövligt beteende på arbetsplatsen är ett fenomen som uppmärksammats allt mer på de svenska arbetsplatserna. Syftet med undersökningen var att undersöka om det finns ett samband mellan upplevt ohövligt beteende på arbetsplatsen och hur detta är kopplat till individuella skillnader i personlighetsfaktorerna agreeableness och openness, samt till ålder och upplevd anställningstrygghet. Detta undersökWorkplace incivility is a phenomenon which has been observed increasingly in Swedish workplaces. The aim of the study was to examine whether there is a relation between experienced workplace incivility and how it is connected to individual differences in the personality factors agreeableness and openness, as well as to age and experienced job security. This was examined through a cross-sectional s

Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures

En studie i arkitektoniska kvaliteter i tid och rum Detta projekt är något av en lågmäld hyllning till en typ av arkitektur som utgör en bas i många av våra städers yttrekantsområden. Byggnader som inte från början var menade att göra något väsen av sig, men som i en senare kontext står ut och attraherar. Ambitionen är att undersöka vilka komponeneter som genrerar dessa platser; som på något sät

Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissio

The concept of this research is that by applying the proposed method, the trajectory of drift into failure can be made visible. The method itself consists of two sequential steps. For research purposes a third step is added. The first step is constructing a phased narrative, consisting of all the changes that have taken place within a particular organisational process subject to research. What has
