Popular science summary: The Battle Against Cancer Daily, people are diagnosed with cancer, a disease that brings suffering and despair. I'm sure you have heard about chemotherapy and radiation as a way of trying to treat cancer, but it is equally important to find an effective method to quickly and reliably detect a tumor at an early stage, before it is too late. In my master's thesis,
Africa stands on the doorstep of a global information revolution that presents a range of opportu-nities. ICT has enormous potential to contribute to the development of Africa, both on an indi-vidual and societal level. The purpose of this study is to examine what effect increased ICT use has on secondary school students in Mutomo, Kenya. Furthermore the study presents a mapping of the secondary s
This master thesis explores the concept of ecosystem services, in the context of urban planning in Swedish municipalities, with the purpose of putting together a planning development tool for urban ecosystem services. The working process consisted of three steps: (1) to identify problems in the Swedish planning process, (2) to identify relevant aspects of ecosystem services and comprehensive plann
This Master Thesis has been performed at Svenska Spel with the aim to detect playing customers probability to churn, i.e. quit their gambling. The first part of the Thesis consists of some previously work done within the field, some facts about Svenska Spel and explanations of used software. The next part describes how the work has been done and the third part give the reader the theory behind the
The purpose of this paper is to investigate the possibilities of optimizing the production of paper pulp in a Conical Disc (CD) refiner for different production rates, taking into account the variables that are thought to be the most important for the production. These include three separate dilution waters, conical disc gap and flat gap. Another task is to compare the values of these variables af
Denna uppsats har haft som ändamål att undersöka om den svenska skadeförsäkringsmarknaden har karakteriserats av en premiecykel under åren 1988 – 2012. Utifrån tidigare forskning har teorier diskuterats vilka förklarar olika skäl till varför premier på försäkringsmarknaden tenderar att röra sig i cykler. Uppsatsen visar med hjälp av en autoregressiv model att den svenska marknaden, i likhet med va
This thesis describes the development of a temperature control system for optical spectroscopy experiments with rare-earth doped samples. Low temperature emission spectra were afterwards recorded for a series for Eu3+ singly doped and Ce3+, Eu3+ codoped Y2SiO5 samples. The analysis and assignment of the different energy transitions is presented. The experimental setups used in this thesis involve
We study an extended bootstrap percolation process in several steps in dimension one, assuming noncyclic boundary conditions. We study the asymptotic behavior of the process as the size of the underlying graph goes to innity. We nd a phase transition with respect to the initial conditions. The phase diagram on the set of initial conditionals of the extended process is described completely. This pr
The thesis treats a partial implementation of the SCORM standard for an existing LMS (Learning Management System), and includes an overview of the standard and a presentation and analysis of the implementation. SCORM is short for Shareable Content Object Reference Model and is a standard for web based e-learning. The standard specifies, among other things, API, aggregation and data model. The impl
The aim of this study is to analyze whether the presence of weed species resistant to herbicides is related to landscape heterogeneity and environmental variables. C3 and C4 weed species, such as Chenopodium album, Conyza canadensis, Amaranthus retroflexus, Papaver rhoeas, Sorghum halepense, Echinochloa crus-galli and Lolium rigidum, are studied in two differing bioclimatic countries, Greece and G
The pattering of an optical surface with physical features like with very low reflectivity and high transmission of IR or visible light can be used e.g. for antireflective windows for solar cells and photodetectors. Here we present results on antireflective patterning of Si for back side illuminated InAsSb nanowire long wavelength IR (8-15 µm) photodetectors. Photolithography and dry etching techn
Utvecklandet av diabetes och ätstörningar sammanfaller ofta kring pubertetsåldern hos både unga kvinnor och män. Då prevalensen av både diabetes typ 1 och ätstörningar ökar kan det vara intressant att studera ett eventuellt samband. Syftet med studien var att sammanställa forskningsresultat kring ätstörningar hos unga personer med diabetes mellitus typ 1. Studien genomfördes som en litteraturstudi
Även om sjuksköterskan är medvetet om hygienens betydelse i sitt dagliga omvårdnadsarbete är följsamheten till handhygien fortfarande låg. Vårdrelaterade infektioner är fortfarande ett stort problem inom hälso-och sjukvården. Syftet med denna litteraturstudie var att belysa faktorer som påverkar sjuksköterskans följsamhet till handhygien. Metoden var en litteraturstudie som baseras på ett urval av
The world´s total expenditures regarding leisure travelling and related expenditures corresponded to approximately 3000 billions USD in 2010. This substantial value makes the travelling industry and related markets important in an economic aspect. Data posted by the WTO states that between the years of 1995-2005 the world’s amount of tourism arrivals increased by approximately 50 %, and additional
Smärta är problematiskt vad gäller personer med demens då deras kognitiva förmåga gör det svårt för dem att förmedla sina upplevelser av smärta. Detta ställer särskilda krav på sjuksköterskan och annan hälso- och sjukvårdspersonal eftersom upplevelse av smärta förmedlas på andra sätt och därför måste observeras. Syftet med denna studie var att belysa olika smärtskattningsskalor samt belysa faktore
För patienter med cancer är cancerrelaterad smärta ett vanligt problem som orsakar ett stort lidande. Syftet var att beskriva användandet av musik i förhållande till omvårdnad av vuxna patienter med cancerrelaterad smärta. Resultatet visade genom teman att musiken kunde lindra såväl fysisk som psykisk/emotionell cancerrelaterad smärta samt att användningen och graden av smärtlindring påverkas av s
The mast cell mediator histamine is involve in T2D pathogenicity Diabetes mellitus is a common metabolic disorder which is characterized by high glucose levels in blood and urine. Diabetes is one of the most expanding diseases in the world today. There are 2 major types of diabetes; type 2 diabetes (T2D) contributes with up to 90% of all diabetes subtypes. Patients with T2D compose up to 150 mill
Concepts as the entrepreneurial city and the creative class closely correlate with the ideas presented in the theory of neoliberalism and neoliberal urban planning policies. These concepts have spread widely throughout the modern world and effect the planning of almost every city today, from developed countries to developing countries. Typically seen as a stronghold for social democratic policies
Syftet med denna studie är att behandla interaktioner mellan fordon och fotgängare i högtrafikerade T-korsningar, där man med hjälp utav mikrosimuleringsprogrammen VISSIM och VISWALK mäter de olika fördröjningar som kan uppstå vid ett övergångsställe beroende på vilken typ av korsning vi har att handskas med. I detta arbetet så kommer vi att behandla T-korsningar med väjningsplikt respektive trafi
