Objective. To analyze the experience of a single centre using stent-grafts for treatment of complicated acute aortic type B-dissections (EVR-ABD). Design. Retrospective analysis of prospectively collected data from patients undergoing EVR-ABD between January 1997 and December 2004. Methods. EVR-ABD was performed in 31 patients (20 males, median age 74. years (IQR: 64-79)). Indications for treatmen

As climate change have become generally accepted as a potential problem, reducing the greenhouse gas emissions and global energy demand has become an important research topic. This have led to an increased interest towards the retrofitting of the existing building stock, including cultural protected buildings. Due to the cultural protection, carrying out major alteration such as exterior wall retr

Det har sagts att alla arkitekturepoker brukar nå sitt bottenmärke någonstans runt 30 år. Under en praktik på ett arkitektkontor upplevde jag det på egen hand när jag arbetade med ett område i Stockholm. Strategin för området är att riva stora delar av dess bebyggelse från 80- och 90-talet. Jag uppfattar strategin som ett uttryck för en allmän impopularitet av arkitekturen från denna period — den It has been said that all architectural eras tend to reach their lowest point of popularity somewhere in their 30s. During an internship, I experienced it first hand when I worked with an area in development in Stockholm. The strategy for the area was to demolish most of its buildings from the 1980s and 90s, buildings that are relatively young. I perceive the strategy as an expression for a genera

The features of social media platforms not only enable the communication between citizens and political actors or institutions, in the form of comments, but also help in magnifying citizens’ voices and opinions and facilitating mass mobilization or political protests. The European Union institutions seem to understand the capacity of social media as a locus for citizen engagement, be it activism o

The objective of this study was to investigate potential differences in gender and place of origin on intimate partner violence (IPV) attitudes, self-silencing beliefs, and sexist and feminist measures in a sample of young adults between 18 and 30 years. Furthermore, it examined whether exposure to videos containing either sexist or feminist humour impacted participants’ level of IPV attitudes, se

The objective of this thesis was to investigate how double skin facades (DSFs) meet daylight and energy requirements compared to single skin facades (SSFs), also considering the life cycle costing (LLC) of both solutions. A South facing, an unobstructed glazed office building in Sweden was used as a basic building object, where SSFs and DSFs were iteratively applied. A mid-level floor was chosen a

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

Background/Problem Description: The purpose of project management is to keep track, organize and assure that the specific goal of a project will be accomplished before the project ends. Without a project management model, it is hard for an organization to monitor and fulfill the purpose of project management. Therefore, ESSIQ AB believes it would be beneficial to have a project management mode

Sveriges regering satte 2011 upp mål om att bli bäst på att utnyttja digitaliseringens möjligheter. Digitaliseringen av bygglovsprocessen har trots det gått långsamt. Bygglovsprocessen idag (2018) är en långsam, dyr och ineffektiv process. Möjligheten att söka bygglov med e-legitimation finns endast hos 30 procent av kommunerna och 60 procent har någon slags e-tjänst ansökan. Ansökningarna innebärThe Swedish government set up a goal in 2011 of making the best use of digitization opportunities. The digitization of the building permit process has, however, been slow. The process of building permits is today (2018) a slow, expensive and inefficient process. The possibilities to apply for building permits with e-credentials is only available in 30 percent of municipalities and 60 percent have

Toyota Motor Company förändrade världen med sitt produktionssystem. Genom att ta bort aktiviteter som inte adderade värde till produkten, kunde företaget bli agilt med korta ledtider till kunden och till en låg produktionskostnad. För att bli konkurrenskraftiga tvingades företag världen över förändra sina produktionsprocesser och en västlig variant av Toyotas produktionsfilosofi uppstod. Denna varToyota Motor Company changed the world with their production system. By removing activities in the manufacturing process that were not adding any value to the product, the company could become agile and offer products to the customer with short lead time as well as to a low cost. Companies in other countries needed to change their manufacturing processes in order stay competitive and a western var

Purpose: As greenwashing becomes an increasingly prevalent concern in the sustainability industry, the pressure of organizations to be perceived as credible is rising. One strategic approach to enhance perceived credibility is through collaboration with a non-governmental organization (NGO). This study aims to examine the impact of NGO–For-Profit co-branding on the brand attitude of both the for-

Entrepreneurial intentions have been identified as a relevant precursor to entrepreneurial behavior; however, the complexities of entrepreneurial intention remain under-explored. This study examines the impact of offspring involvement with parental businesses on their entrepreneurial career intentions and the indirect roles of perceived desirability and perceived feasibility. Building primarily on

In the end of March this year (2023) UN’s Intergovernmental Panel on Climate Change (IPCC) declared humans are to blame for the 1,1-degree global warming of our planet. Furthermore, that the Paris Agreement will fail. Our lifestyle and energy consumption are unsustainable, and the emissions must now be reduced within a few years to mitigate the effects of climate change. The transport sector is o

There is a rising demand for decarbonizing the building sector since it significantly contributes to global carbon emissions. With a focus on the mechanical, electrical, and plumbing systems specifically, this master’s thesis explores the embodied carbon within these building service systems. Utilizing established life cycle assessment methodologies, the case study thoroughly examines the embodied

Objective The purpose of this study was to evaluate the effect of wet clothing removal or the addition of a vapor barrier in shivering subjects exposed to a cold environment with only limited insulation available. Methods Volunteer subjects (n = 8) wearing wet clothing were positioned on a spineboard in a climatic chamber (–18.5°C) and subjected to an initial 20 minutes of cooling followed by 3

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

Popular Abstract in Swedish Multikonjugerad Adaptiv Optik för Astronomiska Teleskop 1. Atmosfärisk turbulens Allt sedan man på 1600-talet började bruka optiska instrument inom astronomin, för att understödja det mänskliga ögat då man beskådade stjärnhimlen, har astronomer strävat efter att bygga allt större och bättre teleskop för att kunna se längre ut i rymden och skönja allt ljussvagare objekt.This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future. The first part is an introductory exposition on atmospheric turbulence, adaptive optics (AO) and MCAO, esta

Prostate-specific antigen (PSA) and human prostatic glandular kallikrein (hK2) have 79% identity with the primary structure. When we used recombinant hK2 protein, only 7 of 23 monoclonal anti-PSA IgGs (monoclonal antibodies, MAbs) cross-reacted with hK2, which enabled us to design a novel immunofluorometric MAb-MAb assay for the specific detection of hK2. In the first incubation, an excess of MAb

Popular Abstract in Swedish Hur kan nattaktiva insekter se i mörker med fel sorts ögon? Majoriteten av alla dagaktiva insekter har en sorts facettöga som kallas appositionsöga. Appositionsögon är anpassade till ett liv med god tillgång på ljus ? nattaktiva djur har därför i princip alltid andra sorters ögon (superpositionsögon). Anledningen till att appositionsögon fungerar bäst på dagen är att dDue to our own preference for bright light, we tend to forget that many insects are active in very dim light. The reasons for nocturnal activity are most easily seen in tropical areas of the world, where animals face severe competition for food and nocturnal insects are able to forage in a climate of reduced competition and predation. Generally nocturnal insects possess superposition compound eye
