Africa is an important part of the global carbon cycle. It is also a continent facing potential problems due to increasing resource demand in combination with climate change-induced changes in resource supply. Quantifying the pools and fluxes constituting the terrestrial African carbon cycle is a challenge, because of uncertainties in meteorological driver data, lack of validation data, and potent
Popular Abstract in Swedish Standard-12-avlednings-EKG är fortfarande ett av de viktigaste och vanligaste redskapen för att diagnostisera hjärtsjukdom trots att ett flertal olika undersökningstekniker har utvecklats under åren. Vid standard-EKG används 10 elektroder, 6 på bröstkorgen och 4 distalt på armar och ben. Inom både industrin och akademin har många års arbete lagts ned på utveckling av deThe standard 12-lead electrocardiogram (ECG) remains one of the most important and most frequently used tools for diagnosing cardiac diseases, although several different examination modalities in cardio¬logy have been developed over the years. The standard ECG uses 10 electrodes placed on well-defined positions on the body, 6 on the torso and 4 distally on the limbs. Both industry and academia hav
Popular Abstract in Swedish Benskörhet (osteoporos) är ett tillstånd som definieras av låg benmassa och ökar med stigande ålder. Osteoporos är idag en av de stora folksjukdomarna och man räknar med att en tiondel av alla män och en fjärdedel av alla kvinnor i Sverige drabbas. Tillståndet är i sig symptomfritt men ökar risken att råka ut för ett benbrott (fraktur) redan vid lättare fall. Frakturer The aim of this thesis was to evaluate risk factors for bone fragility and fractures in postmenopausal women in a long-term perspective. The study period spanned from the age of 48 to age 82 and is thus unique in its length. The studied sample was homogeneous and consisted of 390 north European women from a population-based cohort. At the start of the study, general health and lifestyle parameters
Synthesis of mediators of fever, pain and inflammation as well as protection against reactive molecules and oxidative stress is a hallmark of the MAPEG superfamily (membrane associated proteins in eicosanoid and glutathione metabolism). The structure of a MAPEG member, rat mictosomal glutathione transferase 1, at 3.2 angstrom resolution, solved here in complex with glutathione by electron crystall
This thesis concerns the numerical approximation of the solutions to hyperbolic conservation laws. In particular the research work focuses on reconstruction techniques; the reconstruction being the key ingredient in modern finite volume schemes aiming to increase spatial order of accuracy. To better conform to the nature of the solutions to the hyperbolic problems, the reconstructing fu
The MAX-IV storage rings are being studied at MAX-Lab. In this paper, we present the magnetic measurements of the soft bending magnet prototype. The magnet is introduced in the matching section of the 3 GeV storage ring lattice [Tarawneh, Proceedings of European Particle Accelerator Conference, July 2004, Lucerne, Switzerland] mainly to reduce the power of the synchrotron radiation hitting the ups
Many issues in computational vision can be understood from the interplay between camera geometry and the structure of images and objects. Typically, the image structure is available and the goal is to reconstruct object structure and camera geometry. This is often difficult due to the complex interdependence between these three entities. The theme of this thesis is to use invariants to solve these
1. Growth and reproduction of Daphnia fed lake seston were measured in two categories of meso- to eutrophic lakes differing with respect to terrestrial organic matter influence (humic and clear water lakes). The content of highly unsaturated fatty acids (HUFA), P and N, as well as the taxonomical composition of seston were analysed.2. Seston HUFA and C : P ratios were similar between lake categori
We have found a (dense) basis for the N-representable, two-electron densities, in which all N-representable two-electron densities can be expanded, using positive coefficients. The inverse problem of finding a representative wavefunction, giving a prescribed two-electron density, has also been solved. The two-electron densities are found to lie in a convex set in a vector space. An algorithm to co
The screen-printed four-electrode system was used as the amperometric transducer for determination of phenols and pesticides using immobilised tyrosinase. peroxidase. acetylcholinesterase and butyrylcholinesterase. Acetylthiocholine chloride was chosen as substrate for cholinesterases to measure inhibition by pesticides, hydrogen peroxide served as co-substrate for peroxidase to measure phenols. T
During recent years the nuclear decay modes of discrete prompt proton and a-particle emission from (super)deformed high-spin states have been discovered in nuclei in the Vicinity of Ni-56. The latest news from experiments performed at EUROBALL and GAMMASPHERE regarding these decays are presented and discussed.
The main aim of this project was to peel off the epitaxially grown nanowires (NWs) from their native substrate and transfer them to the cheaper carrier substrate in order to make solar cell device from transferred NWs. Potentially the peeling and transferring idea is about to decrease the cost of NWs growth by reusing the native substrate especially for expensive material such as InP and GaAs whic
This thesis aims to identify online branding channels used by SMEs and determine which of those channels are the most effective. For this, a quantitative study of four SME brands is conducted and their online branding efforts analyzed. The findings add to the existing theory in the field as well as propose a new framework for analyzing and classifying SMEs online branding channels. The gathered da
Sammanfattning Den här uppsatsen är en granskning av brittisk, svensk och kanadensisk upphovsrätt. Mer exakt utreder detta arbete de olika ländernas syn på parodier och hur dessa skyddas under respektive lands upphovsrättslag. För att få en bättre förståelse för om parodier kan kvalificeras som upphovsrättsliga verk, berör även denna uppsats vilka olika kriterier varje land har satt upp för att Summary This paper examines the copyright laws of the British, Swedish and Canadian systems. More precisely it investigates the different countries views on parodies and in what way they are or aren’t protected under their Copyright Act. To get a better understanding of parodies and how they can qualify as a copyright work, this paper also deals with the different requirement each country has set
The goal of this master thesis was to examine some of the available development tools for augmented reality in mobile applications. The best development tool were then used in development of an application for Android or iOS. The thesis has two main parts, the analysis of development tools and the application development. During the analysis ve dierent commercial development tools for augmented re
The possibility to print out metallic components with complex 3D-structures is could revolutionize the industry. In this master’s thesis the cause of process parameters have been investigated for three alloys; stainless steel, 316L, two nickel-based alloys, a derivative of Alloy 738 and 939. Microstructure, porosity, tensile testing, impact toughness, hardness and surface roughness was investigate
Value-at-Risk (VaR) forecasting in the context of Monte Carlo simulations is evaluated. A range of parametric models is considered, namely the traditional Generalized Autore- gressive Conditional Heteroscedasticity (GARCH) model, the exponential GARCH and the GJR-GARCH, which are put in the context of the Gaussian and Student-t distri- butions. The returns of the S&P 500 provide the basis for
This study gives an insight how new technology-based-firms (NTBFs) take part in investment readiness programmes (IRP) in practice and how this differs from the theoretical model by Mason and Harrison (2001). The first part of this study focuses on NTBFs, the role the play in the economy, the challenges they face and their need for financial resources. Furthermore, this paper explains the theoretic
This master thesis is on Statistical Process Control (SPC). The objective is to evaluate if SPC can be used in a process that produces plates for heat exchanger, the process evaluated is located at Alfa Laval Lund AB. The products are produced in the process by punching and shearing metal coils. An ambition in the project is also to increase the knowledge about Statistical Process Control at Alfa
