This article reviews endovascular strategies for aortic arch repair. Open repair remains the gold standard particularly for good risk patients. Endovascular treatment potentially offers a less invasive repair. Principles, technical considerations, devices and outcomes of each technique are discussed and summarized. Hybrid repair combines less invasive revascularization options, instead of arch rep
Syftet med förevarande uppsats är att belysa den sakrättsliga problematiken kring lösöreköp genom att undersöka huruvida avtalsprincipen är förenad med tillräckligt stora fördelar för att ersätta den nu gällande traditionsprincipen. Traditionsprincipen har tillämpats i svensk rätt sedan 1800-talet. Dessförinnan erhöll en köpare skydd mot säljarens borgenärer genom köpeavtalet, i enlighet med avtaThe purpose of this essay is to throw light upon the complexity of the branch of law as regards the Swedish law of property and inquire whether the advantages of the doctrine of consensus exceed the benefits of maintaining the existing doctrine of traditio. The doctrine of traditio has existed in Swedish law since the 19th century. Before that, the buyer obtained protection against the seller’s cr
Denna studie riktar sig mot anställda som arbetar i gruppboende som innefattas av Lagen om stöd och service till vissa funktionsnedsatta (LSS). I flera sektorer inom den offentliga sektorn sker det en ökad detaljstyrning och den anställde får ett alltmer omfattande administrativt ansvar. Syftet med studien är därför att öka förståelsen för vilken betydelse styrdokument och riktlinjer har för den a
The purpose of this work was to contribute to the creation of a prototype of a new type of robot called Agile Parallel Kinematic Manipulator or AgilePKM for short. Designing, building and controlling a new type of robot is a task which goes beyond the scope of any master thesis project, but there are subtasks which are more suitable to handle within the available time frame. A principle design wil
A transition probability is essentially a likelihood of ’something random’ transitioning from one state of being to another. Though, more formally, for all intents and purposes, the ’something random’ is a sequence of random events, which is a stochastic process. There are many stochastic processes that are valuable to understand. Examples can be found in a multitude of topics, from finance to biol
I dagsläget finns det otroliga mängder data som ackumuleras bland företag och i organisationer. Denna datan kan användas för att förstå och förbättra produkter, tjänster och processer och i slutändan bidra till att förbättra samhället. En del av denna data innehåller dock personlig information som kan användas för att identifiera en person, vilket kan vara problematiskt ur ett etiskt perspektiv omCollecting and storing data is easier and more common than ever before. A lot of this data is personal data, which is problematic to store and use both for ethical reasons and because of legislations. In some scenarios the personal information in the data is not interesting or relevant for the given task but it is still collected and stored as a byproduct of the data collection. In these scenarios
Amelogenin is a major constituent of enamel matrix protein that is responsible for the development of tooth enamel. Due to its self-assembly and physicochemical properties, amelogenin has been widely used as one of the natural biomaterials. Amelogenin, along with the other enamel matrix proteins have been known for its regenerative properties. The purpose of this project is to evaluate the enginee

Adaptive reservation is a real-time scheduling technique in which each application is associated a fraction of the computational resource (a reservation) that can be dynamically adapted to the varying requirements of the application by using appropriate feedback control algorithms. An adaptive reservation is typically implemented by using an aperiodic server (e.g. sporadic server) algorithm with f
Three methanogenic biofilm bioreactors were studied to evaluate the performance of three types of carriers. The carrier material were consisted of sisal fibre waste, pumice stone and porous glass beads, and the bioprocess evaluated was the methanogenesis anaerobic digestion of sisal leaf waste leachate. Process performance was investigated by increasing the organic loading rate (OLR) step-wise. Th
Background: Treatment decisions can be difficult in men with low-risk prostate cancer (PCa). Objective: To evaluate the ability of a panel of four kallikrein markers in blood-total prostate-specific antigen (PSA), free PSA, intact PSA, and kallikrein-related peptidase 2-to distinguish between pathologically insignificant and aggressive disease on pathologic examination of radical prostatectomy (RP
Genom denna kvalitativa studie undersöks dansstuderandes behov av musikundervisning vid högre dansutbildningar. Studiens empiri är främst baserad på intervjuer med fyra informanter med lång tids yrkeserfarenheter av dans inom olika områden. Genom informanternas uttalan-den om dans och musik bearbetas frågeställningen om rytmik som musikpedagogisk metod kan varaen hjälp för danselever att närma sigTitle: Eurhythmics at professionaldance educations. A study based on four persons' experiences of eurhythmics and music education at professional dance educations. This qualitative study examines dance students' needs for music education at professional dance educations. The study's empirical work is based primarily on interviews with four informants with longterm professional experie
Our purpose of this study was to investigate older people's ability to ask for help and understand the experience of asking for help, from a care managers perspective. Through a better understanding we can help the care managers in a better way to motivate and assist the elderly. We used qualitative method and interviewed seven care managers in a medium sized municipality and in a small munici
Syftet med denna studie är att ta reda på hur elever reflekterar över sitt eget lärande inom rytmikämnet och hur detta generellt påverkar deras lärande. Målet är att genom tolkning och analys av elevernas svar kunna utveckla rytmikmetoden och därmed bidra med material till den vetenskapliga litteratur som idag finns inom detta område. Ett delmål är också att bidra till utveckling av metoder för reTitle: Eurhythmics, learning and reflektion. Student insights on the significance of reflection in their personal learning experiences. The purpose of this study is to find out how students reflect on their learning process in eurhythmics and how this in turn affects their overall learning. The interpretation and analysis of student responses will be used to further the development of eurhythmics
Utveckling och testning av reaktorer för katalysmätningar Katalysatorer är oumbärliga i såväl livsprocesser som industriella tillämpningar. Bilismen är ett exempel där katalysatorer används vid såväl bränsletillverkning som avgasrening. Men detta är långt ifrån det enda användningsområdet. Katalysatorer är också delaktiga i tillverkningen av uppemot 90% av alla kemikalier. Industriella katalysaIn this project four reactors for studies of heterogeneous catalysis have been developed. They were tested using case studies, especially concerning methane oxidation over palladium. The test measurements showed that the reactors work or would work very well after slight modifications. The first reactor allowed for activity measurement using mass spectrometry for temperatures up to at least 1000°C
The Potential of Esters as Renewable Fuels: Determination of Laminar Burning Velocities Biodiesel fuel is widely used as a clean fuel in car engines. Ester fuels are a one kind of a biodiesel fuel which includes many chemical compounds. Due to their chemical and physical properties these esters are difficult to investigate in a laboratory. The heat flux method was used in this study to determine
The Latin American music genre reggaetón has since its very recent emergence gained massive audiences, and is today widely listened to all across the region. The song lyrics have, however, received criticism for allegedly reinforcing stereotypical gender roles built on machismo and sexist values, partly because of the majority of reggaetón producers and performers being men. This thesis aims to ex
The aim of this study was to use case study approach to show educators that identities of immigrant students are complex, and a response to the dominant culture. The cases were four immigrant students in grades 8 to 10 in Iceland. Through interviews, and observations, data was gathered on how the students construct their identities in the school con-text, with a focus on teachers’ expectations. Th
