Saturated pool boiling heat transfer of HFE-7200 is investigated experimentally on copper surfaces with nanoparticle coatings at atmospheric pressure. The coatings are generated by an electrophoretic deposition method. Two modified surfaces are prepared with Cu-Zinc nanoparticles of 0.3 mg and 0.6 mg, respectively. During the deposition, ethanol works as the solvent while the electrical potential
Early results of mitral valve replacement were reviewed in 336 unselected patients, 261 without and 75 with concomitant coronary artery bypass grafting (MVR and MVR + CABG groups). Early (less than 30 days) mortality was 7% in the MVR and 16% in the MVR + CABG group, with cardiac failure as the dominant cause. In multivariate analysis, the variables most strongly related to early mortality were co
Thin ion transmission detectors can be used as a part of a telescope detector for mass and energy identification but also as a pre-cell detector in a microbeam system for studies of biological effects from single ion hits on individual living cells. We investigated a structure of graphene on silicon carbide (SiC) with the purpose to explore a thin transmission detector with a very low noise level
Context: Somatostatin inhibits a range of hormones, including GH, insulin, and glucagon, but little is known about its role in the development of cardiometabolic disease. Objective: The objective of the study was to investigate whether fasting plasma concentration of N-terminal prosomatostatin (NT-proSST) is associated with the development of diabetes, coronary artery disease (CAD), and mortality.
Objectives: Patients with antineutrophil cytoplasmatic antibodies-associated vasculitides (AAV) exhibit higher mortality than the general population. In the current study, we assessed whether cluster affiliation based on clinical presentation might predict mortality. Methods: With case record review, the outcomes for a population-based cohort of patients diagnosed with AAV in southern Sweden (catc

Abstract Breast cancer is the most commonly diagnosed type of cancer in women worldwide. Inherited or acquired aberrations of genes in DNA damage repair, cell cycle checkpoint, apoptosis, and growth signaling pathways are responsible for the generation of breast cancer. Recently, increasing evidence shows that signaling pathways can be highly interconnected and are interacting with each other rat
I mitt arbete har jag valt att studera kopplingen mellan musik och bildkonst. Min upplevelse är att musik blir förstärkt av konsten och vice versa. Jag har skrivit kompositioner som ska spelas till ljusfilmer av ljuskonstnären Åsa Wirling. Hon kommer projicera filmer på en duk, samt på musikerna. Musik talar starkare till mig genom bild och vad jag valt att studera är förhållandet mellan musik ochIn the preparations for my degree concert, I have chosen to study the connection between music and visual art. In my opinion, music becomes stronger in collaboration with other art genres and vice versa. My original compositions will be performed live, with abstract films made by the light artist, Åsa Wirling, will be projected simultaneously behind and on the band. To me, music speaks stronger th
Detta arbete behandlar överslagsdimensionering av plattrambroar, och syftar till att undersöka hur kostnads- och miljöaspekter påverkas av ramens tjocklek för vanliga spännvidder och fria höjder. Detta för att ge ett bättre utgångsläge vid dimensionering av plattrambroar för framtida projekt. En plattrambro modelleras och analyseras med hjälp av programvaran BRIGADE/Standard och parametrarna spännThis study aims to make a preliminary design of an integral bridge with frame abutments, and to see how the frame’s thickness for common spans and heights affects cost and environmental aspects. This is done to give a better starting point when designing slab bridges in future projects. A slab bridge is modelled and analysed with the use of the computer software BRIGADE/standard with parameters su
Reliable methods for estimating financial return volatility are crucial in many areas of trading and investing. Two such frameworks, the GARCH and SV, have been of particular interest to academics and practitioners alike. The GARCH model describes the variance of the current innovation as a function of the actual sizes of the previous innovations. In contrast, the stochastic volatility model descr
A dye-binding method using Acid Orange 12 was investigated regarding its suitability for the quantification of available lysine, as a means of monitoring the Maillard reaction in skim milk powders. The method was evaluated by analyzing a wide range of milk powders produced by three different drying methods and stored under various conditions. A pilot-scale freeze-dryer, spray-dryer and drum-dryer

Distinct lake-level fluctuations, low lake organic productivity, and open, treeles
As a relatively new form of financial asset with unique properties, Bitcoin is increasingly included in portfolios to improve performance. However, research remains limited on how Bitcoin actually affects portfolio performance. This study aimed to broaden the field of research by exploring whether Bitcoin can improve portfolio performance during a global crisis. It sought to answer the question by
Syftet med uppsatsen är att undersöka hur familjevåld påverkar bedömningen av barnets bästa i frågor om vårdnad, boende och umgänge. Med våld avses våld riktat mot någon annan i familjen än barnet. Jag har använt mig av tre frågeställningar för att lyfta fram vilken betydelse våldet har för barnet. Den första frågeställningen är mer övergripande och handlar om hur våldet påverkar barnets bästa. DeThe aim of this thesis is to examine how domestic violence affects the decision of what is in the best interest of the child with regards to parental authority judgments. In this thesis the term domestic violence refers to all violence towards another family member except the child himself. The thesis is built upon three questions in order to highlight the impact domestic violence has upon the dec
Sammanfattning Sedan den första november 2008 har metoden för framställning av muntlig bevisning i hovrätt ändrats. Med anledning av reformen ”En modernare rättegång” moderniserades rättegången i hovrätten. Moderniseringen innebar bland annat att ljud- och bildupptagning som gjorts i tingsrätten, i regel spelas upp som muntlig bevisning i hovrätten. Nu finns förslag på att den delen av hovrättsförSummary Since November 1st 2008, the method of presenting oral testimonies in the Swedish Court of Appeal has changed. Since the reform “More modern court proceedings” the trials in Court of Appeal have become modernized. The modernization meant, inter alia, that audiovisual recording that have been conducted at the Swedish District Courts are, as a rule, played at the Court of Appeal. The recordi
Denna uppsats har klargjort utvecklingen av våldtäktsdefinitionen och det rättsliga skyddet mot våldtäkter i väpnade konflikter sedan 1900-talet. En rättsdogmatisk metod har använts med betoning på folkrättens rättskällelära, där två centrala frågeställningar har granskats. Denna studie har utrett gällande rätt, inklusive tre banbrytande rättsfall: Akayesu, Furundžija och Kunarac. Uppfattningen This thesis has clarified the development of the definition of rape and the legal protection against rape in armed conflicts since the 1900s. A legal dogmatic method has been used with an emphasis on the sources of law in international law, where two central research questions have been reviewed. This study has examined current law, including three groundbreaking legal cases: Akayesu, Furundžija a
Denna studie undersöker utrymning genom inåtgående dörrar, något som bör undvikas enligt svenska byggregler när antalet personer i en lokal överstiger 30. Trots detta är de specifika utmaningarna och påverkande faktorerna, särskilt vad gäller personer med nedsatt rörelseförmåga, till stor del outforskade. För att belysa detta genomfördes en litteraturstudie samt utrymningsförsök med 36 deltagare (This study investigates evacuation through inward-opening doors, a practice discouraged by Swedish building regulations when occupant numbers exceed 30. Despite this, the specific challenges and influencing factors, particularly regarding individuals with movement impairments, remain largely unexplored. To address this gap, a literature review and eight evacuation scenarios involving 36 participan
