Sommaren 2018 var ett rekordvarmt år, och en markant ökning på solkurvor konstaterades av Trafikverket. Det finns flera orsaker till varför en solkurva uppstår, förutom den ökade temperaturen. När en solkurva bildas dras slutsatsen i många fall att anledningen endast är hög temperatur och vidare undersökningar utesluts direkt. Detta examensarbete består till stor del av en litteraturstudie som bThe summer of 2018 was a hot year, a significant increase of sun curves was observed by Trafikverket. There are several reasons why a sun curve occurs, in addition to the high temperature. When a sun curve is formed, the conclusion is drawn in many cases that the reason was heat and no further investigations are made. The project consists a literature study that explains the physical theory, fac

Ortho-amides have shown to be an important intermediate in the total synthesis of the cytotoxic indole alkaloid, dehaloperphoroamidine. The potential of this functional group lead to further investigation of its reactivity. Background, known reactions with ortho-amides and A 7-steps synthesis route of a general ortho-amide from tryptamine are presented here. Lack of time resulted in that the synth

The purpose of this paper is to find possible measures to tackle algorithmic collusion, caused especially by pricing algorithms, from the perspective of competition law. This paper does not intend to analyse all possible measures that may exist, but rather, focus on a few measures that are seen reasonable. Before proceeding further to analyse these possible measures, the concepts of algorithms and

In this study four different types of PIR materials have been tested to examine the possibility to use the cone calorimeter (ISO 5660) as a screening tool to evaluate the fire properties of the insulation. As such, manufacturers can be able to make a quick control of the insulation without having to spend resources on full scale testing. One of the materials was from an FM-approved (standard 4880)

I ett försök att begränsa bostadsproblem i Nairobi, som är så enorma att det blir en av Kenyas regerings "fyra stora agenda" som innebär topp regeringens prioriteringar när det gäller utveckling. Denna studie fokuserar på den största staden i Kenya (hänsyn till befolkningen), Nairobi. Nairobi växer i befolkning med en takt på över 4% vilket gör det till en av de snabbast växande städer p

The access to safe and clean drinking water is a major concern throughout the world. The recent discovery of coal and gas in Mozambique has increased the economic growth lately and large international companies have been attracted to Tete province in central Mozambique. Coal mining is widely recognized as one of the most hazardous forms of natural resource extraction for human health and the envir

The goal of this thesis is to create a model that can simulate traffic on a highway by primarily using a supervised artificial neural network. The reader is first introduced to the theory of artificial neural networks, step by step from the fundamental principles to the network that is used in the final model. The network is trained to predict velocities of individual vehicles when being fed information

Purpose of the study – The purpose of the study is to develop a conceptual framework and model for further research, of front-line logistic workers ́ perception of sharing their personal information at their work. Furthermore, the study aims to create a framework for how to study information disclosure programs potential impact on employee turnover when being implemented on intermediate parties, n

Syftet med projektet var att utvärdera katalysatorer med olika formuleringar för pre-reformingprocessen. Tre av de fem som testades tillverkades av studenten genom incipient wetness impregnation-metoden. BET-analys visade att katalysatorerna med Θ-alumina hade störst porvolym, den med γ-alumina hade däremot störst ytarea. Testerna gjordes i en tubreaktor som hade gasutloppet kopplat till en GC förThe purpose of this project was to perform a screening on catalysts with different formulations for the pre-reforming process. Three of the five catalysts tested were made by the student using the incipient wetness impregnation method. BET analysis showed that the catalysts with Θ-alumina had the greatest pore volume, while the one with γ-alumina had the greatest surface area. The tests were done

All words in Swedish have a particular melody. There are two tonal patterns that are observed in different prosodic and morphological contexts – accent 1 and accent 2. The tone of accent 1 is the default melody in Swedish and is said to be of intonational nature. The melody of accent 2, on the other hand, only occurs in presence of certain suffixes in the word, hence, accent 2 is claimed to be a p

Companies always strives to acheive as eective inventory control as possible. At the same time, a suciently high delivery accuracy to satisfy the customer is pursued. One prerequisite for successfully accomplishing this is to anticipate customer demand in advance. An approximation of the demand in advance is called forecasting. Forecasting implies that dierent techniques are used to predict future

Indoor Air Pollution (IAP) resulting from indoor burning of solid biomass fuels in poorly ventilated kitchens is a severe health risk in parts of the world where energy poverty is prevalent. Passive ventilation, i.e. taking advantage of naturally induced airflow has been suggested as crucial in reducing IAP levels below safe limits. Residents in high altitude settlements are however exposed to ext

Bakgrund: Majoriteten av patienter på en akutmottagning upplever smärta. Långa väntetider påverkar tiden till smärtlindring. Tidigare forskning har påvisat brister i sjuksköterskors kunskap och inställning till smärta och smärtlindring, men har inte studerats i svensk akutkontext. Syfte: Genom enkäten Knowledge and Attitudes Survey Regarding Pain (KASRP) undersöktes kunskap och inställning kring

Samtidigt som e-handel blir allt mer vanligt förekommande finns det också ett ökat intresset för hållbarhet i samhället. Detaljhandeln går därmed i två utvecklingsinriktningar som ej tycks gå hand i hand. Dagens detaljhandelsföretag tvingas att hantera både e-handelns konsumtionsmönster och konsumenters ökade krav och förväntningar, samtidigt som samhället begär företag att agera mer hållbart. Syf

I Hässleholm pågår ett omvandlings- och förtätningsarbete för att bland annat lösa behovet av bostäder. I nordvästra delen av staden ligger Kvarteret Norden som är ett av de områden som kommunen planerar att bebygga med främst bostäder. Syftet är att skapa en god boendemiljö med en stadsmässig karaktär. Det är inte tätheten i sig som eftertraktas, det är snarare de kvaliteter som den täta stadsmil

För att ta reda på vad som legitimerar digitaliseringen inom SFI har två myndighetstexter, en från Skolverket och en från Utbildningsdepartementet, analyserats utifrån ett diskursanalytiskt perspektiv. I analysen framkommer det att digitaliseringen inom SFI legitimeras genom såväl auktoriseringslegitimering som moralisk legitimering i form av värderande ord och positiva konnotationer. Digitaliseri

This project was conducted focusing on the traditional Japanese dish sushi. The dish and concept have been on a steady rise on the Swedish market as well as becoming a favorite in the hearts of swedes. There are difficulties surrounding prepping and handling of sushi and malpractice can easily occur. If malpractice should occur, it could lead to many consequences as serious as food poisoning. From

På gränsen mellan Helsingborgs och Bjuvs kommun ligger ett område vars förutsättningar för grundvattenuttag bedöms vara dåliga. Av den anledning har en undersökning utförts över en förkastning, tolkad av SGU i just detta område, för att se om denna kan vara vattenförande eller om det kan finnas andra vattenförande strukturer i berget. Förkastningen och det omkringliggande området har undersökts meIn an area on the border between Helsingborg and Bjuv municipality a fault has been mapped by the Swedish Geological Survey (SGU) and since this area have poor prerequisites for groundwater outtake this is of big interest. This is also the reason why this survey have been carried out to try to identify if the fault is water-bearing and to find its position with a better accuracy then could be gath

This study’s purpose was to gather Swedish immigrants’ stories about integration connected to the labour market. The data was gathered through ten semi-structured interviews with immigrants participating in labour market activity. To interpret them Honneth’s theory about recognition were mainly used, but also an intersectional perspective to understand the difference within the group. The conclusi
