Research on dark matter has been ongoing for almost a century. Findings show that dark matter makes up 27% of the universe’s density and thus it is a crucial component of understanding how the universe came about. This thesis describes the key pieces of evidence for the existence of dark matter and its properties. An emphasis is put on the effects of dark matter on processes in the early universe.

This thesis describes the process and the approach taken to determine the current limitations and potential improvements of the GPX Porosity prototype. To continue the development of the GPX Porosity instrument, a series of comparative measurements has been performed on pharmaceutical ribbons, to understand better what are the factors limiting the optical porosity measurement precision and if oth

Introduction: Validation of a new test method to determine nicotine from chewing gum extracts with ultra high-performance liquid chromatography. Background: In Quality Control-laboratories, the methods that are regularly used are consistently developed in order to conduct effective analysis procedures. The aim of all of these developments is to simplify the analysis as much as possible and make t

Background: Previous study found that 2 batches of Nopal flour supplied by the same suppliers at different time was performing different results in in vitro studies and the quality of Nopal flour might thus be different. Besides, investigation on whether the soluble or the insoluble fraction of the Nopal flour suspensions contributed to the glycemic modulation was still necessary. Method: Compo

There are over 1.1 million small- or medium-sized enterprises (SMEs) in Sweden. But even if they have a significant impact on both the country’s economy as well as creating a majority of all Swedish jobs, the current research within competence development has in large, overlooked SMEs. The purpose of this study is therefore to fill that gap by investigating current practices and facilitation of co

I denna uppsats har jag undersökt den litteräre arketypen jurodivyj eller ”dåre för Kristi skull” och hur denna har utvecklats i den ryska litteraturen. Jag har kommit fram till att karaktärstypen kan porträtteras väldigt annorlunda från hur verklighetens exempel på heliga dårar har framställts i de hagiografiska helgonberättelserna. De underliggande skälen till denna utveckling går att hitta hos In this thesis, I have examined the literary archetype of the yurodivy or “fool for Christ’s sake” and how it has developed within Russian literature. I find that the character may be portrayed significantly different from the real-life yurodivy depicted in the hagiographic tales. The roots for this development are mainly found in Fyodor Dostoevsky, who constructed what is called the “stylized hol

Hur lantbruket kan bidra till omställningen mot en 100% förnybar elproduktion. Skiftet från fossil till förnybar energi är centralt i kampen mot klockan för att begränsa den globala uppvärmningen. Ett av målen för Sveriges långsiktiga energipolitik är att elproduktionen ska vara 100% förnybar år 2040. Lantbrukare har stora tak- och markarealer som skulle kunna nyttjas i högre grad än de gör idag As part of a sustainable energy system, Sweden has declared a target of 100 % renewable electricity production by 2040. Farmers have the potential to further this process and simultaneously contribute to a decentralized energy system. This study aims to identify drivers and barriers for the adoption of solar and wind energy production in the agricultural sector. Furthermore, it examines how policy

The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. Human activities' continuous greenhouse gas emission has contributed to global climate change, which has caused some atmos

District heating is a common means of space and hot water heating in Sweden. However, the demand for heating is not the same at all times. On a yearly basis more heat is required during winter, while next to none is needed in summer. Since the demand for heat load varies throughout the year, when trying to predict it, using a model that changes with the seasons can give a more accurate prediction.

It is commonly assumed that algorithmic curation of search results creates filter bubbles, where users’ beliefs are continually reinforced and opposing views are suppressed. However, empirical evidence has failed to support this hypothesis. Instead, we suggest that filter bubbles may result from individuals acting selectively on information made available by search engines. When presented with sea

Government and individual responses to the coronavirus disease 2019 (COVID-19) pandemic have had significant health and economic consequences. Governments imposed measures, including lockdowns, designed to suppress transmission and alleviate the burden on health systems, while private individuals exercised voluntary social distancing, compliance with government-imposed measures and exhibited incre

Purpose: This study aims to add and extend onto the existing studies regarding open innovation in SMEs but to tackle it from a neglected angle that is operating during times of uncertainty. Additionally, this study seeks to explore the mechanisms which SMEs use to reduce R&D budgets, increase the quality of innovations and continue the pace of innovations during the COVID-19 pandemic.

Att vissa plaster kan brytas ned med hjälp av mikroorganismer och deras enzymer i jord, kompost och andra biologiskt aktiva miljöer är det långt ifrån alla som vet. Dessa plaster, en del av de så kallade biopolymererna, kan brytas ned till väldigt små delar som organismerna sedan kan dra nytta av genom att de får i sig bland annat energi och kolväten för att fortsätta leva, växa och förökas. I denThe use of biopolymers instead of traditional fossil fuel based and non-biodegradable polymers is seen as a positive step forward towards a more environmentally friendly future. This project investigates a granule product that is used in a dishwashing system with the aim of gaining knowledge about how it is affected by the storage in between uses and its biodegradability. The product is based on a

PolyAl, the material composed of laminated polyethylene (PE) films and aluminum (Al) in carton, is a challenge in recycling due to the strong adhesion of the layers and the low value of the end products. In Europe, recent efforts to improve the circularity of carton packages include the chemical separation of PolyAl, in order to obtain higher values of the PE and Al separately. However, an undiagn

The purpose of this thesis is to examine how criticism of the Broadway musical Hamilton is received and argued about when it comes to the representation of certain characters. The overall research question is How are discursive productions of historical retelling and identification created by the musical Hamilton? and it will be answered by dividing the question to How does the debate surrounding
