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

Introduction: Lung imaging with synchrotron light sources is currently a widely studied field. The image resolution and quality are remarkable and the level of detail possible to study the smallest structures, the alveoli, of the lungs cannot be obtained by any other non-invasive imaging modality with the current technology. The most common and useful type of lung imaging with brilliant light sour

Purpose: Improvements in mortality rate of glioblastoma patients have been limited during the past decades, due to the tumor’s rapidly growing and infiltrative behavior and resistance to current therapy. Recent findings show that higher brain mean dose strongly correlates with inferior overall survival and that local recurrences mainly occur centrally in previously irradiated regions. This project

Aim: The aim of the study is to characterize the dependency of image quality on absorbed dose for two breast tomosynthesis (BT) systems, GE Senographe Pristina and Siemens Mammomat Inspiration and compare the systems. The image quality was evaluated by different parameters such as: in-plane and in-depth spatial resolution, artifact spread function (ASF) and signal-difference-to-noise ratio (SDNR).

Purpose/Background Dual Energy Computed Tomography (DECT) have been clinically available for over ten years. Two such systems are currently used at Skane University Hospital (SUS) in Lund. By utilizing materials different attenuating properties at different energies, material decomposition and iodine quantification is possible. The aim of this master thesis was to compare the two DECT systems and

Introduction: Carpal tunnel syndrome (CTS) is a common condition especially for people with diabetes, obesity or women who are pregnant. Diagnosing CTS has primarily been performed using electroneuronography. In this thesis the aim was to use an advanced method of tractography to measure and evaluate diffusion tensor imaging (DTI) parameters between anatomical landmarks at the distal radioulnar jo

Within the field of medical radiation protection, radiation safety and personal dosimetry, there is a constant pursuit for improving existing methods and evaluating new approaches for measuring and quantifying the radiation doses that hospital staff may be exposed to in their clinical work. There are numerous ways of determining what doses the staff are being exposed to and the most commonly used
