Purpose: Direct percutaneous access to the carotid artery (diPerCa) during endovascular aortic arch repair (EVAAR) can potentially present a minimally invasive access with lesser local adverse events. Techniques: A retrospective review of consecutive EVAAR between January 2018 and January 2024, in a tertiary referral center, was performed to identify cases, in which diPerCa was used. Patients who
Pesticide exposure can be harmful to insect pollinators and the ecosystem services they provide. As many pesticide guidelines warn against applying such products when pollinators are active, it is important to evaluate how pollinator activity changes with time of day to determine the most appropriate time to spray.We walked transects from sunrise to sunset in oilseed rape (Brassica napus L.) field
Membrane filtration of kraft black liquor (KBL), a side-stream of the pulp and paper industry, is challenged by membrane fouling caused by its multicomponent complexity. The specific contributions of the components found in KBL to the fouling and the characteristics of the fouling layer that they create has not been investigated. Herein, the adsorptive and desorptive behaviours of KBL ultrafiltrat
The purpose of this thesis is to answer the question: is it possible to outperform the OMXS30 index by using an investment strategy based on the Black Swan theory? With increased globalization and technological development, the world has become more and more complex and economic models and theories cannot capture all the sources to risk. There are also several limitations to the human mind which m
Den 1 januari 2014 infördes de svenska reglerna om forskning och utveckl-ing. Reglerna infördes mot bakgrund av den positiva effekten innovation en-ligt nationalekonomisk teori anses ha på tillväxt, och att ett skattemässigt inci-tament förväntas leda till ökade investeringar i FoU. Det svenska FoU-avdraget är idag utformat som en direkt nedsättning av ar-betsgivaravgifterna och den allmänna löneThe Swedish rules on research and development were introduced on January 1, 2014, against the backdrop of the positive impact that innovation according to economic theory is considered to have on growth, and the expectation that a tax incentive would lead to increased investments in R&D. The Swedish R&D tax credit is designed as a direct reduction of employer’s social security contribution
ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. By observing historic climate data for the main coun

Stjärnströmmar är strömmar av stjärnor som har blivit ryckta ur antingen klotformiga stjärnhopar eller dvärggalaxer, som är i omloppsbana rund mer massiva galaxer. Forskare har hittat dessa stjärnströmmar runt vår galax Vintergatan. Exempelvis Sagittarius strömmen, som formas från dvärggalaxen Sagittarius, och Palomar 5 strömmen, som bildas av en klotformig stjärnhop. Strömmarna har också observerStellar streams are probes of the properties of their host potentials, giving clues about the host's shape, mass and substructure. There are several observed stellar streams both around the Milky Way and around external galaxies, and they are studied thoroughly. However, the impact of (i) the properties of the progenitor cluster or dwarf galaxy that form the streams, of (ii) the streams' o
Brottet grov kvinnofridskränkning går ut på att brottsliga gärningar begångna av en man mot en kvinna som han är eller har varit gift med eller som han bor eller har bott tillsammans med under äktenskapsliknande förhållanden ska bedömas allvarligare om var och en av gärningarna utgjort led i en upprepad kränkning av personens integritet och gärningarna varit ägnade att allvarligt skada personens s
Greywater, which comes from household sources such as showers, laundry, and dishwashing, is typically less polluted than toilet wastewater and can be treated and reused. In Helsingborg, Sweden, the RecoLab collects and treats greywater from Oceanhamnen separately as part of a source-separated wastewater system. However, the system has experienced is-sues with filamentous bacteria overgrowth, raisi
Oats (Avena sativa) are a valued food product due to their nutritional profile and proven health benefits. However, prior to consumption, they require heat processing to prevent off-flavors and undesirable mouthfeel caused by lipase-catalyzed hydrolysis of lipids. While the heat treatment inactivates lipases, it raises concerns regarding sustainability and oat quality. The discovery of novel funct
This thesis investigates how the integration of post-combustion carbon capture (PCC) systems would affect combined heat and power (CHP) plant performance, using DWSIM, an open- source process simulation tool. A case study on a CHP plant in southern Sweden was conducted, with models simulated for both baseline and CCS-integrated operation. DWSIM proved accurate within a relative error of under 3 %
The aim achieved through this thesis was to ascertain how much the pollutions of black carbon (BC) from each European country systematically deviate from their expected values obtained by inverting a transport model. The model used is based on meteorological observations as well as black carbon values obtained in the past at different locations. It was achieved by fitting a linear regression model

Sedan sent 1800-tal har strålterapi använts för behandling av cancer. 50% av alla cancerpatienter blir någon gång behandlade med strålterapi, som är en avancerad teknik med många olika steg för att uppnå den slutgiltiga behandlingsplanen. Patienten börjar sin strålbehandlingsresa med att bli diagnosticerad och får sin behandling ordinerad. Efter detta startar förberedelserna inför strålbehandlingeBackground and purpose: Magnetic resonance imaging (MRI) only radiotherapy has, due to superior soft tissue contrast of MRI and the possible reduction of systematic uncertainties, grown into a promising technique. The purpose of this work is to investigate parts of an MRI only workflow with synthetic computed tomography (sCT) images generated from MRI. This was done through investigation of treatm
BACKGROUND: Obesity has been increasing in both developed and developing countries. One of the prevention strategies is controlling energy intake. The objective of this research was to examine the effects of four designed whole grain products, i.e. WG 100, WG 50/50, WG 50/50 + RS and KWWB, on colonic fermentation and appetite variables in healthy subjects. METHODS: The determination of dietary fib
The energy use in the building sector is increasing rapidly which contributes to the rise in global greenhouse gas concentration. Energy-efficient buildings are considered as healthy buildings due to the improved air quality and comfortable indoor environment. One million residential buildings were built in Sweden during 1965 and 1975 to minimize the acute housing shortage. This initiative was tak

When constructing roads, it often happens that the contractor have trouble following the documentation intended for the project. When the contractor is unable to follow the documents and instead need new instructions, there is always changed, added or outgoing work. Sometimes this could mean that it is impossible to stay within the road area, for example, to accommodate the slopes, or more land ne
