Bakgrund: Det fanns inga tidigare utförda studier på larynxmasken (LM) AuraGain och överviktiga patienter. Traditionellt har endotrakealtuben varit förstahandsvalet framför LM vid anläggandet av fri luftväg hos överviktiga patienter p.g.a. riskfaktorer som regurgitation med gastropulmonell aspiration. LM AuraGain skiljer sig från andra liknande typer av LM genom att lumen för ventrikelsond tillåte
Most of today’s materials show either high strength with low ductility, or relatively low strength combined with high ductility. It is strongly desired in the industry to obtain materials whose mechanical properties can display a combination of high strength and elongation. That is why the new concept of harmonic structure has been introduced recently. This structure consists of strong ultrafine g
Financial decisions that concerns us are not always made by ourselves. In real life, many situations arise when the decisions are taken for us by a third person. Examples of this are when policy makers decide for us and when brokers handle our investments. Others are estimating the risks for us and makes financial decisions from their perception of the situation and perhaps their own risk preferen
This thesis considers solitary standing wave solutions to the Davey-Stewart-son equation, which is a model for surface waves on a body of water in three dimensions. In a special case, the Davey-Stewartson equation is reduced to the well-known non-linear Schrödinger equation with cubic power which is known to have a countable familiy of radial standing waves. One of the aims of this thesis is to in
Variable incomes and under-investment due to risks of economic loss is an often overlooked aspect of poverty. Affordable insurance against risks such as loss of harvest due to low rainfall may be a key factor in reducing poverty. This study aims to examine the relationship between microinsurance against weather-related risks and levels of investment among covered farmers. The analysis is done by r
Previous research has shown the significance of syndicated loans as an alternative financing source to corporate bonds. This thesis investigates the influence of the financial development of a country on specific syndicated loan terms. Our estimates show that country level dimensions such as banking stability, the efficiency of financial institutions and their depth play a limited economic role in
The main focus of this thesis is Wedderburn's theorem that a finite division ring is a field. We present two proofs of this. The thesis also contains a proof of a theorem of Jacobson and a proof of a generalisation by Artin and Zorn that a finite alternative ring is associative, and therefore a field.
Denna studie ämnar öka förståelsen för hur content marketing och relationsskapande kan ges uttryck i digital kommunikationen mellan ett tjänsteföretag och dess kunder. Studien är av kvalitativ fallstudiekaraktär och det empiriska underlaget består av inlägg publicerade på fallorganisationen Avanza Banks sociala mediekanaler samt delar av företagets hemsida. Materialet har analyserats ur ett sändar
The purpose of this report is to evaluate and assess the fire safety at the sports center Pilängshallen located in Lomma. The report is only focused on personal safety and no consideration has been taken concerning economic or environmental damage. Pilängshallen is used on a daily basis for several different sport and workout activities by both local sport clubs and the public, as well as by scho
Money is often left on the table when corporations issue new securities. Explanations for the underpricing phenomenon are often related to information asymmetry between the investor and the issuer. In this study we investigate factors affecting underpricing on corporate bonds in the Swedish market. To some extent contrary to what was expected, the results indicate that bonds are on average overpri
The purpose of this thesis is to investigate whether factor augmented vectorautoregression (FAVAR) models estimated using principal component analysis are able to improve monthly inflation rate forecasts for Sweden. We produce 42 forecasts for the period January 2012 to June 2015 and evaluate the forecasts by their root mean square errors as well as their ability to correctly predict the sign of t
The aim of this study was to examine social workers perceptions of medication assisted treatment. We have made a qualitative interview study in which we interviewed seven municipal social workers that have knowledge and experience of working with people who have substance abuse problems and medication assisted treatment. We found that the social workers are describing both advantages and disadvant
This thesis investigates the phenomenon of personal branding on social media and, in particular, it examines how successful YouTubers create and build their personal brand via content. The thesis provides valuable input to the existing literature on personal branding, which is predominantly found in self-help books and articles by self-proclaimed gurus within personal branding. Using the method of
Den här uppsatsen undersöker de avancerade metoder av effektivt innovationsskydd under företagskoncentrationsprövningar som finns i USA och EU. Syftet är att finna synergier mellan dessa två system och föreslå nödvändiga förbättringar av det europeiska systemet genom att introducera innovation som en reell standard för prövning, inkludera dynamisk effektivitet, omstörtande innovation och icke-pris
The Swedish Confederation of Trade Unions (LO) presented a new political report in 2015 with the purpose of renewing the wage policy of solidarity. The aim with a renewed wage policy is to create full employment instead of the present mass unemployment, to decrease the wage gap and to eliminate wagedrifts. The renewal may seem a bit strange, when the original policy (also called the Rehn-Meidner m
Sjötelegrafen Köpcentrum is a shopping mall located in Nynäshamn, Sweden. To examine the evacuation conditions in case of fire at Sjötelegrafen, a fire safety evaluation has been conducted. The report presents two dimensioning fire scenarios that are seen as representative for the shopping mall, these are fire in ICA Maxi and fire in Jysk. These different main scenarios were analyzed and simulated
The Jacobian-free Newton–Krylov (JFNK) method is designed to solve a linear system of equations that appears in Newton’s method. It uses the generalized minimal residual (GMRES) method to solve the linear system and a simple function to approximate the matrix-vector multiplications required in GMRES. An advantage of GMRES is the ability to check the residual of a potential solution without doing a
Since the rise of the Islamic State the world has seen a proliferation of public executions in which spectacle and theatricality have come to play an important role. Their propaganda has adopted an aesthetic style in which violence is openly displayed, celebrated and glorified. This thesis explores the role that aesthetics has in the performed and mediated execution videos of the Islamic State, by
