BACKGROUND: High reproducibility of test measurements is often considered an indication of high reliability of test results. The aim of the current study was to analyse the role of the traditional perimetric reliability indices, False Negative and False Positive responses, and Fixation Losses, as indicators of test reliability in comparison with threshold reproducibility in patients with suspect o

The purpose of this essay is to examine the ideas that are prominent in the Swedish disability policy regarding the stated goal of equal participation in society for all. In order to achieve this, I have chosen to focus on two documents, they are SOU 1982:46 Handlingsprogram i handikappfrågor and Prop. 2016/17:188 Nationellt mål och inriktning för funktionshinderspolitiken. I have examined these t

En ny akustisk infångningsenhet med kraftigt ökad kapacitet kan anrika nanopartiklar från kroppsvätskor. Det finns otroligt mycket information att utvinna ur biologiska vätskor som blod och urin. Biomolekyler som proteiner, blodkroppar och RNA kan säga väldigt mycket om en patients hälsa. Denna information är därför väldigt användbar för läkare när de ska sätta diagnoser, men för att få ut någonThis thesis outlines the design and construction of an acoustophoretic trapping device with greatly increased capacity and throughput, compared to current commercial systems. In acoustic trapping, a strong, localised acoustic field is generated inside a channel. This field can capture and retain particles against a flow, allowing for nanoparticle purification and enrichment without the need for ul

Det är väl känt att kolmonoxid (CO) är en giftig och hälsofarlig gas som är luktlös, färglös och smaklös vilket gör den svår att detektera utan analytisk utrustning. Men under senaste åren så har forskning bevisat att i små doser så kan kolmonoxid användas som en terapeutisk substans för att lindra malaria, cancer, lung-, hjärt- och kärlsjukdomar men även reducera mängden inflammatoriska substanseIt is well known that Carbon monoxide is a toxic and hazardous gas, but during recent years it has been proven that using a controlled concentration, carbon monoxide can in fact be used as a therapeutic agent, and can contribute to decrease malaria, treat cardiovascular and lung diseases and potentially even treat cancer, among other things. The main problem in using carbon monoxide directly is th

There is no consensus on how to define and measure green growth. Consequently, we can neither state if growth is actually green nor econometrically explore important questions such as what determines green growth. This thesis takes a three-step approach to move one step closer to a unifying longitudinal cross-country measure of green growth. It analyzes how green growth has been quantitatively mea

Vi lever i en värld där många människor inte har tillgång till rent vatten och faktorer som torka, föroreningar och ett dåligt vattenförvaltningssystem påverkar detta. På grund av sociala, politiska och ekonomiska faktorer, så är det också komplicerat för dessa människor att vara med i beslutsprocesser som kan påverkar deras tillgång till vatten. Men vad skulle hända om man kombinerade två olika vWater-related issues such as drought and water scarcity are problems that many countries around the world are facing. To solve this, multiple efforts have been made to combat these problems such as adopting Integrated Water Resource Management (IWRM) as a management approach. IWRM is a holistic approach that links different water systems and has therefore been popularized and conceptualized by man

When the civil war in Lebanon was ended by the signing of the Taif Agreement in 1989, the consociational democracy was reintroduced to mitigate inter-sectarian tension. Although there has been more than 30 years since the war ended, Lebanon is still a deeply divided society, and the current peace is characterized by reoccurring eruptions of violence and inter-sectarian tension. While the sectarian

During the 21’st century a lot of support has been found by economists that megaprojects all over the world become more expensive than planned. One type of project well known for cost-escalations is traffic infrastructure. The most common theory for this phenomenon is that benefits and costs for these projects suffers from optimism bias, where the former is exaggerated, and the latter is understat

Author: Tekla Münger Title: The Construction of Sex Trafficking – Swedish Policy-making, Effects and the Complexity of a Global Social Problem Master’s thesis SOCM04 Cultural Criminology, 30 credits Supervisor: Erik Hannerz Department of Sociology, spring 2021 The purpose of this qualitative study is to analyse how sex trafficking is constructed and represented as a social problem in policy docum

Purpose: Based on excisting theories within marketing and psychology research investigate how scent marketing can affect customers and whether attitudes towards an ambient scent differ between men and women. Methodology: A quantitative study has been conducted with its starting point in positivism. A deductive approach has been used, meaning that a theory is being proven or disproven using a spec

This paper focuses on constructing models that predict a Value at Risk (VaR) estimation for financial portfolios using hierarchical clustering and copulas. Traditional VaR models often assume linear dependencies and normal distributions, which can be poor assumptions for financial data - especially during extreme market events. This paper introduces a non-linear modeling approach using copulas to

Fed aquaculture is a necessary practice to meet the seafood requirements of a growing population in a sustainable manner. There is a high demand for fish feed to meet the rising protein requirements of the industry. Currently, fish feeds are either unsustainable, affected by seasonal variations, lack a complete amino acid profile, lack scalability, or are too expensive. Single Cell Protein (SCP) i

Automatic segmentation of organs and tissues in computed tomography (CT) images can aid clinicians in anatomical contextualization for planning surgery or dosimetry. CT scans can cover varying axial ranges of the body. This thesis aims to develop a neural network based on vision transformers for segmenting organs and tissues in CT images of arbitrary axial ranges. Two models are presented, one bas

This thesis explores the classification of savannah trees using EnMAP hyperspectral and Sentinel-2 multispectral satellite data using a Random Forest classifier. The study aimed to assess if the increase in spectral information from the hyperspectral data gives an increase in classification performance, to find the advantages and limitations to hyperspectral data compared to multispectral data and

With rapidly developing digitalization and the growing popularity of online learning platforms, understanding the psychological drivers behind user loyalty has become increasingly critical. This thesis investigates how Flow Experience, defined as a deep state of intense enjoyment, focus, and concentration, shapes user satisfaction and user attitudinal loyalty in the context of online learning

Companies face the strategic challenge of expanding into adjacent markets or areas. This often requires a choice between building internally, acquiring through purchases, or forming partnerships to address the opportunity. While extensive literature exists on each of these options individually, there is limited research on the decision-making process that evaluates all these alternatives collectiv

We investigated the formation of an abstract concept of same/different in a harbor seal by means of a two-item same/different task. Stimuli were presented on a TFT monitor. The subject was trained to respond according to whether two horizontally aligned white shapes presented on a black background were the same, or different from each other, by giving a no-go or go response. Training comprised of

Human group IIA-secreted phospholipase A(2) (sPLA(2)-IIA) is a bactericidal molecule important for the innate immune defense against Gram-positive bacteria. In this study, we analyzed its role in the host defense against Streptococcus pyogenes, a major human pathogen, and demonstrated that this bacterium has evolved a previously unidentified mechanism to resist killing by sPLA(2)-IIA. Analysis of
