Do negative income shocks increase conflict risk? I study the relationship between desert locust infestations and conflict in 26 African countries. Combining geolocalized data on locust swarms and bands with information on conflict events, I construct two panel datasets at spatial resolutions 0.5◦ × 0.5◦ and 0.1◦ × 0.1◦, covering the years 1997–2017. I find a negative relationship between locust i

Background: Intra- and interfractional variations in anatomy can cause unplanned substantial alterations of the dose distribution of the target in proton therapy. Motion management methods might be used in order to minimize anatomical variations. In the proton therapy of lung cancer, a potential motion management technique is the use of the voluntary breath-hold approach. The aim of this study was

The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. The model was used to analyse an existing system in Denmark with 15 connected single-family detached houses. Each of the houses has a

The purpose of this thesis was to study secondary school students' motivation to learn a second foreign language in addition to English. In addition to the empirical investigation of L3 motivation over a program of study and the testing of the widely-held assumption that L2 English impacts negatively on L3 motivation, the aim was also to contribute to the conceptual development of self-based motiv

Increasing the amount of renewable generation in distribution networks is a fundamental part of the energy transition. Multiple methods exist to increase the hosting capacity in a grid, to allow larger injections of generation and more efficiently utilize existing infrastructure before operational limits are breached. In this thesis, the method studied for this is network reconfiguration. Many dis

The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics.A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect.In two-dimensional materials it leads to so-called helical edge states that exhibit counter-propagating electron sta

The creation of prototypes for the design of new products is a fundamental activity in the metal-mechanic sector that contributes to Bolivia's socioeconomic development. The existence of a multitude of factors that positively or negatively affect the prototype, are encompassed in two approaches: i) prototyping engineering and ii) prototyping management. Research for the design of prototypes suitab

In September 2019, streets across the world filled with millions of children and youth demanding climate action, demonstrating the growing concern young people feel about their futures (Taylor, Watts, & Bartlett, 2019). However, protests are only one of the methods youths use to show their dissatisfaction with current climate change policies. Youth are also utilizing education, entrepreneurshi

Although much research has been done on case and sequence within coordination structures separately, few studies have investigated the impact the two have on each other. Moreover, very little research has dealt with the striking similarity of English and Danish regarding case and sequence within CoDPs. This thesis, therefore, aimed to explore this matter to uncover the complex system which determi

This thesis concerns oaths, curses, and prayers in Roman comedy, more precisely the comedies by the playwriter Terence (185/84 - 159 BC). So-called informal/interjectional oaths and prayers constitute the main focus of this investigation, however, asseverations, formal oaths, formal prayers, and curses are included as well. In this study, carried out by utilizing the methodological frameworks herm

We find ourselves in the midst of a remarkable technological revolution, with rapid advancements in fields such as artificial intelligence, robotics and information technology. Consequently, there is a pressing need for low-power technologies that are not reliant on continuous power supply. The field of spintronics aims to resolve this by coupling electric and magnetic properties. To pave the way

The recent peak in interest for artificial intelligence, partly fueled by languagemodels such as ChatGPT, is pushing the demand for machine learning and dataprocessing in everyday applications, such as self-driving cars, where low latency iscrucial and typically achieved through edge computing. The vast amount of dataprocessing required intensifies the existing performance bottleneck of the datamo

Daylight analysis is often carried out when definitive decisions about space characteristics such as materials, colours, window characteristics and furnishing have not yet been made. Such late design choices, which are first introduced or can still be changed late in the design process or even after its conclusion, impact the daylight levels of interior spaces. This study explored the impact of la

Att människan påverkar klimatet och att utsläpp av växthusgaser värmer planeten är ingen nyhet. Byggsektorn stod 2015 för 18 % av Sveriges totala utsläpp av växthusgaser och 2018 lanserade Bygg- och anläggningssektorn en färdplan för att nå en klimatneutral värdekedja tills år 2045. Tidigare studier har pekat på att majoriteten av klimatpåverkan ifrån flerbostadshus kommer från driftskedet, men seThe emissions of greenhouse gases caused by the construction sector represented 2015 18 % of Sweden’s total greenhouse emissions and the sector had by 2018 published a plan on how to reach a climate neutral value chain by 2045. Studies have shown that the construction phase has become a larger part of the climate impact from new-built multi-family residential buildings than before, in, in relation

In this report, we model the mechanical properties and fracture behavior of SiC nanowires with different polytypes using Molecular Dynamics (MD) simulations. The mechanical properties investigated are the Young’s modulus, the maximum tensile stress and the fracture strain. The three polytype tested are SiC (3C), (2H) and (4H). Tensile tests are performed on bulk and nanowire samples using three com

The benefits and barriers of supply chain mapping have often been discussed in the literature, but there is no existing step-by-step framework that can be followed to map a supply chain. In this master thesis, the authors develop a 12-step framework for supply chain mapping and explore IKEA's Comfort Category using the framework. The framework is divided into three main stages: 1) Before mapping,
