This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. Then we set up the system and discuss the relevant approximations. Moreover analytical expressions of the c
En viss typ av immuncellsansamling i tumörer, så kallade tertiära lymfoida strukturer (TLS), hos patienter med bukspottkörtelcancer verkar inte alltid vara så gynnsamt som forskning tidigare visat. Förekomst av många TLS i tumören kunde i studien kopplas till kortare överlevnad och kan möjligen bero på att cellgiftsbehandling förändrar funktionen TLS. I denna studie studerades två typer av immuncPancreatic cancer (PC) is a devastating disease and is almost always synonymous with a poor outcome. Chemotherapy is the standard treatment and is administered in either an adjuvant or palliative setting. However, nearly all patients, regardless of treatment intent, eventually develop chemoresistance. Little is known about the events causing chemoresistance, but increased knowledge is essential fo
This essay examines the European Parliament resolution of 5 May 2022 on the impact of the war against Ukraine on women. The analysis is based on a descriptive idea analysis, which helps me map out which ideas and political actions that are adopted by the European parliament in the resolution. The essay also investigates the EU:s understanding of female exploitation and vulnerability in the Ukraini
Bilismen ökade explosionsartat under det svenska 1900-talets mitt. För att möta bilens utökade ytkrav och den olycksvåg som drabbade Sverige skulle samhället moderniseras och rekonstrueras, och det fort. Föråldrade kvarter revs, nya förorter anlades med bilen i åtanke och motorvägar såg dagens ljus. Samtidigt integrerades bilen med näringslivet, skapande köpcentra och industrier. Den fysiska miljöThe expansion of automobile usage in the middle of the 20th century gave rise to a car-centric planning, changing the Swedish society. New considerations and ideas favoured motorised planning, creating a car dependency and marginalisation of active transport like cycling. As a result, cost-benefit analyses are disregarding the benefits of cycling, making bicycle projects such as bicycle highways s
The UK government is legally bound to reach net zero greenhouse gas emissions by 2050 as part of its actions to address climate change. One prominent method of decarbonisation is carbon capture and storage (CCS), slated for deployment in two industrial clusters by the mid-2020s. Fossil fuel companies are the operator behind the rollout of this technology: given the historical reticence of these co
The thesis aims to answer the research question: To what extent was the increased Economic Policy Uncertainty during the Financial Crisis associated with the decline in Swedish exports from January 2007 to January 2010? During the 2008 Financial Crisis, Swedish trade fell by ten percentage points, slightly more than the world average. The thesis aims to investigate whether the increased EPU at the
Några utav de vanligaste orsakerna till att en brand uppkom mellan 2010 och 2020 var ”bränder som medvetet startades” samt ”bränder som startats av gnistor vid tågbromsning”. Av den totala mängden bränder som uppkom stod tågbromsning för cirka 1.1 % av dem och den anledning som stod för absolut störst andel bränder var ”bränder startade utav okänd anledning” vilket stod för 43%. KlimatförändringaForest fires can start in a variety of ways. "Fires started deliberately" and "fires started by sparks generated from a train braking" were two of the most common causes of fires between 2010 and 2020. Train braking accounted for 1.1% of all fires, whereas fires created by unknown reasons accounted for 43% of all fires. The climate is expected to change in the future, and sinc
In recent years, the construction industry has faced unprecedented challenges related to abnormal price increases on building materials, which have not been experienced since the 1970s oil crisis. These price hikes have been caused by a various of factors, including the COVID-19 pandemic, war in Europe, trade sanctions and high energy prices. Consequently, fixed-price contracts face the risk of si
Digital tools are part of the everyday lives of social workers. In the political discourse surrounding the digitalization of social services, this development tends to be described as a naturally occurring force of change. What seems less prominent is how digitalization also carries values and ideas designed within the framework of a social and political context, digital tools are consequently not
This paper analyzes the existence of market power on the Nordic electricity market between 2018-2022, and if the energy market turbulence caused by covid-19, and later deepened following the war in Ukraine affected producers' bidding behavior. Market power was tested using Cournot assumptions to see if producers withheld output strategically when demand was more inelastic. Auction data on syst
In today's world, plastic pollution has become a widespread problem with plastics in oceans, rivers and forests. The use of plastic has increased rapidly since it first was developed and that is because of its advantageous abilities. This scientific report focuses on the evaluation of two enzymes known as "autotransporter domains containing esterase" for its ability to degrade a vari

Detta examensarbete undersöker möjligheten att förbättra produktnivåmätningen i en av Tetra Paks fyllnadsmaskiner, eftersom den nuvarande lösningen inte detekterar den med den önskvärda precisionen, samt mätområde. Idag används en magnetisk flottör tillsammans med 16 separata kapacitiva sensorer. Problemet med detta är att förpackningar blir avvisade på grund av en felaktig mängd produkt. Detta skThis thesis examines the possibility to improve the product level sensing in one of Tetra Pak’s filling machines, because the current solution does not detect this with the desirable precision, as well as measuring range. Today, a magnetic float is used together with 16 separate capacitive sensors. The issue with this is that packages get rejected due to a faulty amount of product. This occurs bec

Intresset för att genomföra denna studie springer ur våra tankar från två områden – dels positiva erfarenheter av kamratrespons inom andra skolämnen än musik, dels positiva erfarenheter av att spela i band där feedback mellan medlemmar spelar en central roll. Studien tar avstamp i två frågeställningar: vilka faktorer påverkar kvaliteten av kamratrespons i ensemble ur ett elevperspektiv och vilka eThe interest in conducting this study arises from our thoughts and findings from two main areas. Firstly, our positive experiences from peer response in other subjects than music, and secondly, our positive experiences from playing in bands where the feedback between members plays a key role. The study starts with two questions: what factors affect the quality of peer response in ensemble lessons
Stålindustrin är den industrisektor som har högst utsläpp i världen. Ståltillverkning tillskrivs cirka 8 % av världens totala C02-utsläpp. Från den utgångspunkten är behovet av djup avkarbonisering av stålindustrin är uppenbart. Det mest gynnsamma alternativet för att fasa ut fossila bränslen från produktionen av stål är att övergå till ståltillverkning från grönt väte. I denna rapport undersöks kThe steel industry is the most emitting industry sector in the world. Steelmaking attributes to around 8 % of the world’s total CO2 emissions. From that standpoint the need for deep decarbonization in the steel industry is evident. The most viable option for removing fossil fuels from the production of steel is to move to steelmaking from green hydrogen. In this report comparative advantages for g
