Neutrons have a magnetic moment that interacts with magnetic fields. This has been put to use to study magnetic materials. Polarised neutron imaging (PNI) is one such application that allows the observation of, for instance, magnetic domains and domain walls inside a sample. To facilitate a PNI experiment, the neutron beam from a neutron source needs to be polarised, meaning that the magnetic mome
Innovationshöjden för automatiska skjutdörrssystem under de senaste årtionden har resulterat i högteknologiska automatiska skjutdörrar, där tillbehören och användargränssnitten inte har utvecklats i samma utsträckning. Det har lett till att programväljare för skjutdörrar blivit omoderna och svåranvända för användarna. Syftet med denna masteruppsats var att tillsammans med ASSA ABLOY Entrance SysteThe innovation of automatic sliding door systems over the past decades has resulted in high-tech automatic sliding doors, where accessories and user interfaces have not been developed to the same extent. As a result, operating mode selectors for sliding doors has become outdated and difficult for users to operate. The purpose of this master’s thesis was to propose a new design for operating mode s
Special hatha yoga classes for musicians and variations of postures (asana) in normal yoga classes. Why and how to apply the different branches of hatha yoga in a yoga class. Practicing breathing exercises (pranayama), concentration (dharana)/meditation (dhyana), postures (asana) and relaxation (savasana). Safe physical exercises without pressure/bodyweight on hands and wrists. I chose postures co
Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others. The range of exper
Med ökande koncentrationer av koldioxid (CO2) i atmosfären kan energieffektiva tekniker för koldioxidinfångning (CCS) bli viktiga för att växthusgasutsläppen ska minska. Rapportens syfte har varit att experimentellt bestämma och utvärdera fyra egenskaper hos lösningar av vatten, dimetylsulfoxid (DMSO) och aminoalkoholen 2-amino-2-metyl-1-propanol (AMP) som ska användas i en pilotanläggning. Vid inWith increasing atmospheric carbon dioxide (CO2) concentrations, energy efficient carbon capture and storage (CCS) technologies could prove important to enable reductions in the global CO2 emissions. The aim was to investigate a novel, non-aqueous, and precipitating chemical absorption system of dimethyl sulfoxide (DMSO) and 2-amino-2-methyl-1-propanol (AMP), which forms solid carbamate salt cryst
The presented thesis focuses on dynamics of capital structure decisions of financially constrained and unconstrained firms listed on Stockholm Stock Exchange. It examines the effect of the global financial crisis on the corporate financing decision. The first chapter introduces the topic, discusses its importance and outlines the contribution to the empirical research. The second chapter the relev
Flooding of urban areas is a worldwide problem as cities grow and the amount of impermeable surfaces increase generating more surface runoff. In the Zambian city of Ndola, the capital of the Copperbelt Province, flooding occurs in some parts of the city especially on Dag Hammarskjöld Drive at the underbridge, which has been flooding every rainy season consecutively for 8 years now. The main object
The production of single cell biomass by the collaboration company in this project for use as a meat alternative is a potential source of sustainable alternatives to functional ingredients for the food industry. With its high protein content, creating a protein isolate from the single cell biomass became interesting and a study of single cell protein functionalities could offer a possibility to in
In Sweden, what we eat accounts for about a third of the consumption-based greenhouse gas emissions, and there is strong evidence that the most effective way to reduce emissions is to switch to a more plant-based diet. A shift is currently underway in the Swedish food system; the market for plant-based products is showing an exponential growth, coupled with, for the first time since the 1950s, a d
The growing number of African Presidents on Twitter affirms that media, in all its forms, will always play a fundamental role in contemporary politics. Moreover, based on its face value, the presence of Presidents on Twitter could suggest that citizens are gaining unprecedented access to their president. But, this thesis contends that the newness of Twitter should not blind us into thinking that t
The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. The test program is for the first scoping test that will be performed o
A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes
Frågan om en kriminalisering av karteller inom den hårda kärnan har sedan millennieskiftet utretts tre gånger inom ramen för statens offentliga utred- ningar. Varje gång har detta avstyrkts. I USA har kartellsamarbeten däremot varit kriminaliserade sedan 1890. Idag tillämpas hårda straff, enskilda förtag har fått betala hundratals miljoner dollar i böter och många personer har dömts till långa fänThe issue of criminalization of hard core cartels has been considered three times in Swedish Government Official Reports since the turn of the millen- nium. The proposition was rejected every time. In the United States, collusion in restraint of trade has been criminalized since 1890. Harsh punishments are applied, some companies have been fined hundreds of millions of dollars and many individuals
An investigation into the use of statistical texture analysis in combination with ultra high-frequency ultrasound for diagnosing Hirschsprung’s disease (HD); An illness that manifests itself through the absence of ganglia cells in lower parts of the intestine. Current diagnostic techniques carry a higher risk of long-term consequences in newborns and children which enables a new avenue of research
In this thesis the WKB-approximation is used to simulate the tunneling current for an Esaki nanowire diode and the result is compared to data from Esaki nanowire diodes grown with MOVPE. The WKB-approximation with triangular potential barrier predicts a strong increase of the tunneling current as a function of the doping densities and at the highest doping levels it gives lower tunneling distances
The goal of this Master’s Thesis is to investigate the implementation of cryptographic algorithms for IoT and how these encryption systems can be integrated in a NarrowBand IoT platform. Following 3rd Generation Partnership Project (3GPP) specifications, the Evolved Packet System (EPS) Encryption Algorithms (EEA) and EPS Integrity Algorithms (EIA) have been implemented and tested. The latter are b
In the ongoing transformation from previous “one-child policy” to current “two-/three-child policy” in China, the newly issued “supporting measures” system is highlighted to be crucial to boosting fertility. Extant studies on the issue are mostly limited to idealized discussions, while lacking a Public Administration perspective to comprehensively understand the real policy process. To compensate
Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density var
This thesis creates multiple indices to score and rank developing countries with regard to their suitability for engaging in debt-for-climate swaps, and thus identify the most suitable country candidates. The origin of debt-for-climate swaps lies in the 1980s, and after a period of diminished use and attention they have become a topic of discussion again, especially in the last two years. Desp
