Popular Abstract in Swedish Avhandlingen innehåller fyra arbeten om några aspekter på ickelineära paraboliska ekvationer och system. I det första arbetet presenterar vi ett resultat om "quenching" vid dynamiska randvillkor. Det andra arbetet rör global existens av klassiska lösningar till vissa paraboliska system. I det tredje arbetet bestämmer vi optimala konstanter för vissa Gagliardo-NirenbergThis thesis contains four papers about some aspects of nonlinear parabolic equations and systems. Paper 1. A note on quenching for parabolic equations with dynamic boundary conditions We present a quenching result for semilinear parabolic equations with dynamic boundary conditions in bounded domains with a smooth boundary. Paper 2. On global existence for semilinear parabolic systems We presen

In this work, extraction of antioxidant carotenoids from Haematococcus pluvialis microalga, has been studied combining pressurized liquid extraction (PLE), using hexane and ethanol as extracting solvents, and analytical techniques such as thin layer chromatography (TLC) and HPLC with DAD. The effect of the extraction temperature (50, 100, 150 and 200 °C) and the polarity of the solvent have been s

Byggbranschen står för 33% av Sveriges årliga energianvändning. Genom att göra nödvändiga förändringar så som att renovera befintliga byggnader på ett miljösmart sätt kan energi- och miljöbesparingar göras med mer eller mindre enkla medel. I denna studie, som initierades av Trelleborgs Energi AB, undersöktes hur deras kontorsbyggnad kunde bli så innovativ, hållbar och energieffektiv som möjligt. SThe construction industry is responsible for 33% of Sweden’s annual energy consumption. Important environmental and energy savings can be done by renovating already existing buildings with a climate smart mindset. This study was executed on behalf of Trelleborg Energi AB to investigate how their office building can become as innovative, sustainable and energy efficient as possible. The study was a

This thesis involves creating an extending an application called “Var f-n är bussen?” (something like “Where the hell is that bus?”) for the company Trivector Systems in Lund. “Where the hell is that bus?” is an application for smartphones that will show departure time for buses from a chosen bus stop, linepath, bus stops and buses for a chosen bus line and the next bus stops and departure time fr

Background: FTV Capital is a private equity company specializing in growth equity. Even though the company has been very successful, the private equity industry is highly competitive and more and more companies are turning their strategy towards growth equity. To stand out and keep the competitive advantage, having a strong brand and communicating efficiently is particularly important for a privat

Can deterrence work against a rogue state? The following analysis is done in order to test the validity of deterrence theory upon a rogue actor, and if necessary, to try and develop it further. Whereas the security strategy proved successful against the Soviet Union because of mutual assumptions of rationality, it is questionable if it works towards new challenges today. The behavior of rogue stat

Populärvetenskaplig sammanfattning: I det svenska landskapet saknas många av de naturliga våtmarker som fanns innan våtmarkerna dränerades för att göra plats till åkermark. Idag försöker man rekonstruera eller anlägga helt nya våtmarker i Sverige då främst i odlingslandskapet. Detta görs inte enbart för att ge tillbaka en del av det naturliga landskapet och öka den biologiska mångfalden, våtmarkerWetlands are constructed for uptake of nutrients in areas that have exceeded critical loads of nitrogen and also for promoting biological diversity. Wetlands have not only positive effects, they have some negative environmental effects as they emit the greenhouse gases methane (CH₄), carbon dioxide (CO₂) and nitrous oxide (N₂O). There are different ways to construc

Föreliggande uppsats är ett examensarbete på juristprogrammet. Uppsatsen är skriven inom området familjerätt och avser att belysa problematiken av beslutanderättens utformning vid gemensam vårdnad. Syftet med uppsatsen är att undersöka bestämmelsen i 6 kap. 13 a § första punkten FB och hur paragrafen förhåller sig till när vårdnadshavare inte kan nå konsensus Enligt svensk vårdnadslagstiftning äThe present essay is an examination paper for a degree of Master of Law. The essay is written in the area of family law and intends to highlight the problem of decision-making for joint custody. The purpose of this paper is to examine the provision in Chapter 6. 13 a § first point FB and how it relates to when the guardians can not reach consensus. According to Swedish custody laws, it is the be

The soot emissions from diesel engines are much higher in transient operation than during steady state operation. In this thesis, a method for estimating the soot mass flow emission in transient drive cycles is presented. The proposed method uses stationary emission maps in combination with step responses. Bandpass filters are used to filter the engine torque/power to provide transient detection a

Being able to detect nucleated cells in human blood is a very important part of health care. CellaVision has machines which can automatically detect cells in blood samples from peripheral blood instead of using manual microscopy. Sometimes it is not enough to only investigate the peripheral blood but also samples from the bone marrow. The bone marrow is different from the peripheral blood and it i

Cassava peels were pre-treated with alkali, enzyme and in sequential combination of alkali and enzyme, and used for production of bioethanol or biogas, or both (in sequence, bioethanol followed by biogas). The Biogas Endeavour and Automatic Methane Potential Test Systems were used for production of bioethanol and biogas, respectively. The bioethanol yield and volumetric productivity achieved with

The focus in this paper is on how students experience their transition from their education to being employed as engineers in relation to the concept of employability. Four cohorts of students in a master’s programme in engineering were monitored annually with a ‘follow-up’ one year after graduation. Results show that there were differences in the way students talked about their curricular design,

It is not uncommon that states repress and oppress its citizens by exerting violence upon them. Sometimes this violence leads to cases where states abuse their power. This abuse can lead to terrible consequences which several historical and contemporary cases shows. When analyzing state violence, it ought to be put in the context of violence from non-state actors, which often eclipse the violence

This paper valuates two different financial contracts, the European Call and the Spread option using the Fourier transform. In the European Call case the underlying asset is modelled by the geometric Brownian motion stochastic differential equation. All necessary conditions in order for the transform to exists are examined and it turns out that the payoff needs to be scaled by an exponential facto
