I Sverige finns det idag mellan 400 000 – 500 000 geoenergianläggningar och det uppskattas att nettotillskottet energi från geoenergianläggningar är ungefär 18 – 20 TWh per år. Geoenergianläggningar använder markens översta 300 – 500 metrar för att utvinna värme eller kyla. Vid anläggning av geoenergisystem kan man använda olika borrtekniker, mer eller mindre lämpliga beroende på olika geologiska There are about 400 000 – 500 000 shallow geothermal energy systems in Sweden and every year the net additions of energy from geothermal energy systems are about 18 – 20 TWh. Usually it is the upper 300 – 500 meters of the ground that are used for extracting heat or cold from cored strata. When constructing a shallow geothermal energy system, there are different drilling techniques available for u

This thesis is evaluating the pedestrian modelling software Viswalk for the use as a building evacuation model, by verifying and validating the model. In the verification, a procedure from the National Institute of Standards and Technology (NIST) is used as a basis to assess Viswalk’s ability to represent pre-evacuation time, movement and navigation, exit usage, route availability and flow constra

The purpose of this Master’s thesis is to find out which measures for reading promotion are used by school libraries and how these can have an effect in terms of increased reading. This is of interest since surveys have shown that Swedish pupils read less and that their reading abilities have decreased. In order to become good at reading one needs to read a lot and this is why promoting reading is

This study questions the received wisdom that surviving Old Norse loanwords in modern Irish are fewer than 50 in number and are mostly shipping-related. The eventual goal is a complete survey of all Old Norse loanwords still “in common use in modern Irish” (Greene 1976: 80), since nothing of the sort has been found in the literature. In the interim, this study proposes a list of 67 words, extant i

Segregation is a well-known process problem that may cost companies quality and time. The aim of this project was to establish a fundamental understanding about sifting segregation by using the sifting segregation tester described in the ASTM International standard. In this work, Cellets and Suglets were used to study particles tendency to segregate at different weight ratios and different particl

The procedure within the administrative field of law is ruled by norms and principles. The framework governing differs from the procedural law in civil court. The grounds for administrative claims and appeal are established in 29 and 30 §§ FPL. There are also a number of other procedural laws with their own rules for appeals, to which FPL is subsidiary. Amongst the other laws is the law that regul

Kaffeodlaren står inför att hantera den förödande svampsjukdomen ”Kaffebladrost” som förhindrar bladens förmåga att ta upp solljus och kan innebära att upp till 50 % av skörden förloras. Speciellt i tider där kaffepriset sjunker har lett till en sämre hantering av odlingarna vilket främjat spridningen av sjukdomen. Den lägre prissättningen har även lätt till att odlare inte är lika motiverade att Coffee leaf rust (Hemileia vastatrix) is a patogen currently threatening sustainable coffee production all across the world where coffee is grown. Yield losses can reach up to 50 % of the production in Brazil and primarily affect regions at low altitude. Costs associated with the rust has been estimated to 616 million USD from 2012-2014 in Central America. Thus, the purpose of this study was to ev

Kenya’s rapid, unplanned urban development and rising pressure for cities to adapt to climate change and become more climate change resilient has led to the realisation that more needs to be done. In Nairobi, increasing access to mobile technology and internet access, faster internet speeds, and the growing technology sector could be possible means to facilitate urban climate change resilience (UC

One of the biggest expenses for airline companies is the fuel for the aircrafts; preceded only by labor costs it is important for an airline to optimize its use of fuel. One option to save money on fuel is by doing something called Fuel Tankering. Essentially, fuel tankering is a way to lower the fuel cost by refueling at departures where the fuel price is lower than at the destination of the airc

This paper investigates the last two months of the Vietnam War, March and April 1975, from the CIA:s perspective. During the last two decades, the CIA have declassified many documents about the Vietnam war, thus making new source material available. The withdrawal of American troops from Afghanistan and the subsequent Taliban conquest, has also sparked a renewed interest in the Vietnam war. Hence,

Under 2022 hade värdepappersinstitutet Avanza över 1.7 miljoner kunder, och ökade antalet kunde med 100 000 det året. För att försäkra sig om att alla aktörer som handlar med finansiella instrument vill fortsätta handla på marknaden, krävs det att de har förtroende för marknaden. För att aktörerna ska ha förtroende för marknaden är det viktigt alla har tillgång till korrekt information så att de iIn 2022, the securities institute Avanza had over 1.7 million customers, which was an increase by over 100,000 customers that year. To ensure that all actors who trade with financial instruments want to continue to trade, it is crucial that they have confidence in the market. For the parties to have confidence in the market, it is important that everyone have access to correct information so that

Ex vivo organ perfusion is a technique that aims to increase the amount of organ donors by treating an otherwise nonfunctional organ with a perfusion fluid outside of the body to restore its function. UGLK Science is an ex vivo organ perfusion company outside of Lund specializing in kidney transplantation. The organ is perfused in a machine which restores kidney function, allowing the organ to sur

The purpose of this study is to develop a further understanding of how the Swedish Film Institute (SFI) made both Swedish and international film history available through cinema screenings of older films. This MA thesis is a textual analysis and archival driven research study which centers on the SFI's film archival activities in general and their film club in particular, during the period bet

In this master's thesis I will study library space in its practical use in relation to the professionals working in it daily, i.e. the library staff. It seems that this profession should have a unique knowledge base around how the library is used and how space can be organised to benefit the users, the staff and the collections. The library is closely connected to and affected by society and s

The purpose of this study was to examine drug availability and social risk- and safety factors regarding adolescents' drug use. The method used for this study was a survey, with 140 students from Helsingborg's high schools as respondents, allowing a quantitative analysis. The theory used in this study was Albert Bandura's social learning theory. Previous research shows that there are s

Objectives: Coagulation test results may be affected by hemolysis, icterus and/or lipemia (HIL). Detailed guidelines for HIL-management are missing, both for manual and automatic HIL-checks. The aim of this survey was to provide an overview of the practical procedures for the detection and handling of HIL-samples used by laboratories in Europe in the context of coagulation testing. Methods: A Surv

“Seeding” is the addition of preformed fibrils to a solution of monomeric protein to accelerate its aggregation into new fibrils. It is a versatile and widely used tool for scientists studying protein aggregation kinetics, as it enables the isolation and separate study of discrete reaction steps contributing to protein aggregation, specifically elongation and secondary nucleation. However, the see

INTRODUCTION: Alzheimer's disease (AD) diagnosis has been based largely on clinical symptoms, despite their limited sensitivity and specificity. Biomarker use was proposed to support a more accurate and timely diagnosis. However, neuroimaging or cerebrospinal fluid (CSF) is rarely used in primary care due to their perceived invasiveness, cost, and need for appropriate infrastructure. Blood-based b

Considering the distinct etiological pathways and molecular characteristics of different lung cancer subtypes, it is crucial to develop subtype-specific prevention strategies and therapeutic targets. This study aimed to identify protein biomarkers and potential therapeutic targets for specific subtypes of lung cancer by integrating population-based observational studies and Mendelian randomisation
