The present study deals with detection of intra-atrial wavefronts from atrial activation times in adjacent bipolar electrograms. A statistic of the delays within each wave-front was calculated and served as a basis for quantifying the wavefront consistency as well as the propagation of the electrical activity along the catheter. The database consisted of 19 patients for which five electrograms wer
Objectives: To determine if tumor vascularity as assessed by three-dimensional (3D) power Doppler ultrasound can be used to discriminate between benign and malignant ovarian tumors, if adding 3D power Doppler ultrasound to gray-scale imaging improves differentiation between benignity and malignancy, and if 3D power Doppler ultrasound adds more to gray-scale ultrasound than does two-dimensional (2D
Au nanoparticles and Au films for growth of nanowires on the GaAs(111)B surface have been studied by a combination of experimental and theoretical techniques. If Au is present in either form, annealing to temperatures relevant for nanowire growth results in the formation of a thin Au wetting layer. Based on density functional theory calculations and experimental data, a structural model is propose
Det moderna Lagrådet har utvecklats till vad det är idag primärt sedan början på 1900-talet. Efter grundlagsreformen 2010 trädde en reformerad regeringsform i kraft i januari 2011, vilket innebar en viss förstärkning av Lagrådets ställning. Lagrådet utgör en fundamental del av det konstitutionella rättighetsskyddet i Sverige. En av Lagrådets centrala uppgifter är att granska och lämna yttranden omThe current Council on Legislation has developed into what it is today, primarily since the beginning of the 20th century. Following the constitutional reform 2010, a reformed Instrument of Government entered into force in January 2011, which implied a certain strengthening of the Council's position. The Council on Legislation constitutes a fundamental part of the protection of constitutional
Background Introducing services for manufacturing companies can lead to improving customer satisfaction and new revenue streams as well as creating a more sustainable business. However, the current understanding of how this can be done in practice is limited. Purpose This master’s thesis investigates how a manufacturing company can generate sustainable value through the introduction of new repair
A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. This so-called "massive MIMO" promises attractive gains in spectral efficiency with
Miljöbron is a non-profit organization; their main purpose is to merge companies and students into different environmental projects. The projects can be an assignment, practical vocational training or degree thesis. Miljöbron is expanding and the demand from students and companies is rapidly growing. Because of the expansion, a large amount of information needs to be stored and managed in a struct
The modern human being is exposed to different kinds of light during a normal day, both natural light and adjusted lighting. The idea that light affects us is uncontested, and so affecting the light in turn becomes a question of well-being. It is often thought that abundant and strong lighting is good lighting, but this is far from always accurate. Moreover, the light from a regular lightbulb is i
Bovine milk contains several enzymes which can affect the quality of milk. One of these enzymes are lipases which hydrolyse the triacylglycerides in milk. In this process off-flavours, odour and product defects are generated. By controlling the enzymes activity, milk quality can be increased and therefore milk and dairy products can be stored for a longer time. This is desirable since the world de
In February 2009, ST‐Ericsson was formed as a joint venture bringing Ericsson Mobile Platforms and ST‐NXP Wireless together, creating an industry leader in development and design of wireless semiconductor components and platforms. The new company became one of the top players in wireless semiconductors. During the integration, purchasing of indirect material at ST‐Ericsson was outsourced to an out
Since the financial crisis of 2008 many European countries have been plagued by growing fiscal deficits and public debts. The country found by many to be the worst off is Greece and in this study we use the Solow model of economic growth to attempt to find a savings level for Greece which provides enough capital for both investment and debt service. We use two different scenarios where one is base
Som ett resultat av industrialiseringen ändrades varumärkets primära funktion efterhand till att gälla mer i relationen mellan konsumenter och företag. Den tekniska utvecklingen och globaliseringen har lett till en företagskultur där lokala handlare med lokal och i viss mån nationell kundkrets har ersatts av stora kedjor med världsomspännande försäljningsmöjligheter. Förändringarna har resulteraThe primary function of a trade mark changed as a result of the industrialisation period. As time passed the importance moved to regard the relationship between consumers and companies. The technical revolution and globalisation has led to a business culture where local and national vendors have been replaced by giant chains with sales opportunities across the world. The outcome of the modificat
In this paper two different concepts are analyzed: information disorder and cooperation. Psychological warfare has become an increasingly pressing problem during the past few years. Several different notions are being used within the concept, including disinformation, misleading information and information disorder. Problems occur when one has a concept, but no legal definition for it. Hence is th
The aim of this study was to examine the relationship between authenticity and symptoms of anxiety and depression as well as health-related quality of life (HR-QoL) and life satisfaction in the context of the theoretically related constructs of adult romantic attachment, reflective functioning and insight in a convenience sample of Swedish adults. One hundred and ninety-one participants were recru
This is a Master's thesis, and it is a report on a study on different secondary packaging for the Tetra Brik Aseptic 1500 ml Slim package (TBA 1500 S). At the beginning of this study no installed filling line for the TBA 1500 S package existed. The first line was installed in October. Therefore a similar package was studied, the TBA 1000 S package. Data were collected on this package and then
Fighting against accidents with elderly involved have come to be one of the west world's greatest challenges together with the climate changes and epidemics, and in order to fight against these accidents SDF Centre, Gothenburg appointed a man to the post as a caretaker. The aim of this master thesis is to analyse whether the implementation process and the systematic work correspond with Vedun
For some time now, there has been a debate concerning the relationship between the Cultural Heritage of Sweden and the public. It is said that mediation has been, and still is a, one-waydialog between the two. As a result, people have found a new way to interact with our heritage, thru cultural tourism. This area has been blamed for commercializing our Cultural Heritage, but also ignoring the gre
The essential enzyme ribonucleotide reductase (RNR) is highly regulated both at the level of overall activity and substrate specificity. Studies of class I, aerobic RNRs have shown that overall activity is downregulated by the binding of dATP to a small domain known as the ATP-cone often found at the N-terminus of RNR subunits, causing oligomerization that prevents formation of a necessary α2β2 co
