1. 1. Micro-galvanic effects and corrosion inhibition of copper-zinc alloys

   Författare :Mattias Forslund; Jinshan Pan; Christofer Leygraf; Per Claesson; Jin Ying; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Copper; zinc; brass; octadecanethiol; IR Spectroscopy; AFM; atmospheric corrosion; aqueous corrosion; corrosion inhibition; Koppar; zink; mässing; oktadekantiol; IR-reflektions absorptionsspektroskopi; AFM; atmosfärisk korrosion; vattenaktig korrosion; korrosionsinhibering.; Chemical Engineering; Kemiteknik; Kemi; Chemistry;

   Sammanfattning :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. LÄS MER

3. 2. 3d Transition Metals Studied by Mössbauer Spectroscopy

   Författare :Saeed Kamali-Moghaddam; Roger Wäppling; Lennart Häggström; Friedrich Wagner; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Mössbauer Spectroscopy; SQUID Magnetometry; XRD; Layered Structures; Magnetism; Magnetic Superlattices; Nanoparticles; Li-ion Batteries; Brass; Fysik; Physics; Fysik;

   Sammanfattning : Layered crystals with magnetic elements as Co and Fe have been studied. In TlCo2Se2, where Co atoms in one sheet are separated by Tl and Se from the next Co sheet, magnetic interaction within and between the sheets have been studied. LÄS MER

4. 3. Spela snyggt och ha kul : Gemenskap, sammanhållning och musikalisk utveckling i en amatörorkester

   Författare :Gunnar Heiling; Musikhögskolan i Malmö; []
   Nyckelord :HUMANIORA; HUMANITIES; Pedagogy; aesthetic; group-coherence; social community; frame-factor theory; situated learning; non-dualistic; learning; Music; brass band; didactics; Pedagogik; didaktik;

   Sammanfattning : In a Swedish brass band a program for change was pursued which aimed to improve the artistic level of playing of the ensemble without replacing less competent members. At the time for the study the band comprised 34 members, four of whom were female. LÄS MER

5. 4. Numerical Techniques for Acoustic Modelling and Design of Brass Wind Instruments

   Författare :Daniel Noreland; Bertil Gustafsson; Leif Abrahamsson; Björn Sjögreen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acoustic horn; brass wind instrument; loudspeaker; optimization; hybrid method; Numerical Analysis; Numerisk analys;

   Sammanfattning : Acoustic horns are used in musical instruments and loudspeakers in order to provide an impedance match between an acoustic source and the surrounding air. The aim of this study is to develop numerical tools for the analysis and optimisation of such horns, with respect to their input impedance spectra. LÄS MER
