In nature, for example through mechanical degradation (e.g., plastic waste in the sea) and through the exposure to UV-radiation, plastics can degrade to microplastics and eventually to even smaller plastic nanoparticles. Studies performed under laboratory conditions have shown that plastic nanoparticles can accumulate in the liver and the brain of fishes, hence plastic nanoparticles can cause brai
As concerns grow ever larger about the negative effects of CO2 emissions, the use of hydrogen gas as an alternative to fossil fuels is becoming a more attractive objective. This however, requires practical ways of storing and transporting a highly flammable gas and is generally not compatible with much of the existing infrastructure. One proposed solution to this problem is implementation of liqui
This thesis examines the Global Britain discourse and its articulation in the Integrated Review, a foreign policy paper, published by the British Government in March 2021. Global Britain is not a new phenomenon but an imperial legacy. The study highlights this legacy and underlines what British foreign policy focuses on in the future post-Brexit world. Faircloughian critical discourse analysis and
In 5G communications, Non-terrestrial Network (NTN) is envisioned to complement Terrestrial Network (TN) to increase network availability, scalability and continuity. Positioning of User Equipment (UE) is critical for the operation of NTN. Currently, NTN uses Global Navigation Satellite System (GNSS) for positioning. However, the use of GNSS to complement NTN operation has some drawbacks such as h
Packaging of fast food and take-out food involves a significant amount of material that ends up in landfills, recycling and litter. This is because the packaging is designed only for a single-use. There’s no future in single-use products and that includes single-use takeaway packaging. Influenced by the negative image of plastic, individual restaurants and food vendors are increasingly switching
Kristina Sandbergs trilogi om hemmafrun Majs liv med böckerna Att föda ett barn (2010), Sörja för de sina (2012) och Liv till varje pris (2014) är ett stycke episk diskbänksrealism som samtidigt formmedvetet leker med prosakonstens konventioner i syfte att skapa rytm. Denna masteruppsats undersöker, genom en fyrdelad analys, rytmskapande på flera olika nivåer i text. Uppsatsen undersöker trilogins
Background Scania’s production unit in Oskarshamn manufactures and supplies truck cabs to the European market. In order to remain competitive, it is necessary for the company to re-evaluate its competencies and technologies. Thus, it is of great interest for Scania to investigate what value newly acquired technology can provide to the company and its operations. Problem description As a part of S
Trots FN:s 17 globala mål och Sveriges nationella mål om ett fossilfritt Sverige 2045 är bilen fortfarande det vanligaste transportmedlet i Sveriges största städer. Cykeln är ett miljövänligt och platseffektivt alternativ till bilen och många europeiska länder satsar man på att främja cykling idag. Cykelgatan, som är en trafikutformning som har testats i Sverige sedan 2007, syftar bland annat till
Föroreningar i dagvatten är en stor bidragande faktor till dålig vattenkvalitet i sjöar och vattendrag, och en stor andel av dessa föroreningar generas av mänskliga aktiviteter. Dagvattens föroreningssammansättning varierar kraftigt beroende på vilka ytor vattnet kommer i kontakt med. I ett jordbruksdominerat landskap transporteras stora mängder näringsämnen via ytavrinning och dränering till närl
Based on the increasing rate of globalisation resulting in a more diverse workforce, the purpose of this study is to investigate the relationship between diversity and job satisfaction in medical R&D teams. Determining such a relationship is highly valuable for managers of R&D teams to ensure the best possible output from the team, reducing turnover and keeping existing talent within the t
I Sverige planeras det för höghastighetsjärnvägar, med högre hastigheter än vad som används idag, för att binda samman landets tre storstadsregioner. I samband med detta krävs ett utvecklingsarbete av olika järnvägstekniska lösningar där kontaktledning är ett av områdena som utvecklas för att möta högre hastighetskrav. Detta examensarbete syftar på att analysera och jämföra olika kontaktledningssySweden is planning for highspeed railway with higher speed than used today between the country's three large metropolitan regions: Stockholm, Gothenburg and Malmö. In connection with this, various technical solutions, where the overhead catenary system is one area, must be developed further to meet higher speed requirements. This thesis aims to analyse and compare different catenary systems ag
We provide an introduction to scheme-theoretic algebraic geometry, which studies spaces that are in essence locally solutions to systems of polynomial equations, and prove the weak Mordell-Weil theorem. The weak Mordell-Weil theorem states that for an elliptic curve $E$ over a number field $K$, the quotient $E(K)/mE(K)$ is finite for all $m\geq 2$. The proof is adapted from a proof in the language
Bio-based binders have recently been introduced to reduce the dependence on fossil raw materials, which bitumen is produced of. Measurements with dynamic shear rheometer (DSR) and rotational viscometer (RVB) were performed on mixtures with bitumen and two different types of bio-based binders, namely Lignin 1 and Lignin 2. Parameters like softness point, viscosity and parameters used to evaluate ru
Participation in corporate accelerator programmes is considered a powerful tool for early-stage start-ups for operational go-to-market and strategic business development acceleration. With the COVID-19 outbreak, all the activities related to the corporate accelerators were forced to move online. However, due to the novelty of the phenomenon, the influence of switching the modality of corporate acc
Capacity shortages in electricity grids can impose significant costs on society due to missed investments in industry. Due to limited profit opportunities and long lead times, grid reinforcements are not a viable solution to the problem, which must therefore be prevented through efficient use of existing grid resources. Local flexibility markets can financially compensate electricity users to shif
