2. 1. Movement artifact reduction in laser Doppler blood flowmetry : myocardial perfusion applications

   Author : MG Daniel Karlsson; Karin Wårdell; Knut Kvernebo; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Laser Doppler perfusion monitoring (LDPM) and imaging (LDPI) enable assessment of tissue microvascular perfusion. The techniques are based on the Doppler broadening of the optical spectrum occurring when coherent laser light is scattered by moving red blood cells (RBC). READ MORE

4. 2. A Study on Desulfurization of Hot Metal Using Different Agents

   Author : David Lindström; Du Sichen; Nortier Patrice; Shin-ya Kitamura; KTH; []
   Keywords : desulfurization; hot metal; CaO; Mg; CaC2; ZnO; reaction mechanism; desulfurization abilities; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : This thesis deals with desulfurization of hot metal using different agents. The aim of this study was to improve the understanding of commonly used desulfurization agents such as fluidized CaO, CaC2, commercial-CaO, Mg, and mixtures of commercial-CaO-Mg. The possibility to use ZnO for desulfurization of hot metal was also investigated. READ MORE

5. 3. Measurements of High-Precision Atomic Data with Applications to Astrophysics and Cosmology

   Author : Maria Aldenius; Astronomi - Genomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; atomic data; Ca; Cr; Fe; Mn; Mg; metal-poor stars; fine-structure constant; Fourier transform spectroscopy; nebulae; oscillator strengths; spectroscopy; wavelengths; Ti; Zn; Astronomy; Astronomi; Atomic and molecular physics; Atom- och molekylärfysik; rymdvetenskap; space research; cosmic chemistry; kosmisk kemi; branching fractions;

   Abstract : Investigations of astrophysical spectra require accurate atomic data, such as wavelengths and transition probabilities. This thesis provides high-precision atomic data for astrophysical and cosmological applications. The measurements have been carried out using Fourier transform spectrometry on light produced in a hollow cathode light source. READ MORE

6. 4. On the microstructure and mechanical properties of Mg-Al alloys

   Author : Haiping Cao; Linköpings universitet; []
   Keywords : Mg-AI; microstructure; mechanical properties; divorced degree; modeling; mould constraint; segregation band; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The microstructural features and the mechanical properties of binary Mg-Al alloys have been investigated by using a gradient solidification technique. Homogeneous and nearly defect-free samples were produced under well controlled cooling conditions, through which the microstructural characteristics as well as the relationships between microstructure and mechanical properties in Mg-AI alloys were precisely defined.

   Author : Barbro Kollander; Jean Pettersson; Marit Andersson; Jonas Bergquist; Grethe Wibetoe; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi element analysis; trace element; ICP-AES; inductively coupled plasma atomic emission spectromtery; water analysis; liver analysis; non digested samples; medical samples; biological samples; samples from biopsies and autopsies; mice organ; fast analysis; internal standard; preconcentration; matrix elimination; Cu; Zn; Mn; Co; Pb; Cd; Mg; Ca; Fe; Ni; Cr; S; P; K; Al; Analytical chemistry; Analytisk kemi; Analytical Chemistry; Analytisk kemi;

   Abstract : This thesis describes two different sample preparation strategies for inductively coupled plasma atomic emission spectrometry (ICP-AES), and their ability regarding multi element quantification in complex samples. Sensitivity, repeatability, reproducibility and accuracy were investigated. READ MORE
