  1. 16. Mineralogical speciation of sulfur in acid sulfate soils from Luleå, Sweden

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Niklas Gunnarsson; [2018]
    Keywords : acid sulfate soil; metal leakage; low pH; SEM; elemental sulfur; framboidal pyrite;

    Abstract : Marine sulfide – bearing sediments that oxidize when in contact with oxygen and leach outelements in high concentrations to small watercourses have been a problem for many years allover the world especially around the Bothnian Bay. The purpose of this study was to furtherinvestigate the sulfur mineralogy present in acid sulfate soils in the area of Luleå, Sweden. READ MORE

  3. 17. Analys av KC-like som biomarkör för sepsis hos tikar med pyometra

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Caroline Klemming; [2018]
    Keywords : Sepsis; Blodförgiftning; SIRS; pyometra; hund; tik; biomarkör; cytokin; kemokin; CXCL; KC-like;

    Abstract : Sepsis är ett komplext och livshotande tillstånd orsakat av en infektion som skapar en dysreglerad inflammation, vilket ger upphov till ett så kallat Systemic Inflammatory Response Syndrome (SIRS). Mortaliteten vid sepsis är hög hos hund och en tidig diagnos och insättande av behandling är därför mycket viktigt överlevnaden. READ MORE

  4. 18. Coumarin-based molecular probes : exploring the spectroscopic properties of complex mixtures and applications in colloid chemistry

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Shangqing Zhao; [2018]
    Keywords : warfarin; phenprocoumon; fluorescence spectroscopy; ultraviolet absorption spectroscopy; sodium dodecyl sulfate; surfactant; micelles; critical micelle concentration.;

    Abstract : Warfarin is a well-known anticoagulant drug that is used to prevent cardiovascular disease and blood coagulation such as thrombosis. In this study, the main aim was to investigate the photo physical characteristics of warfarin in the different molecular environments provided by sodium dodecyl sulfate (SDS) micelles by using ultraviolet absorption and fluorescence emission spectroscopic techniques.

  5. 19. Ethanol, ethyl glucuronide, and ethyl sulfate kinetics after multiple ethanol intakes : A study of ethanol consumption to better determine the latest intake of alcoholin hip flask defence cases

    University essay from Linköpings universitet/Kemi

    Author : Rickard Lundberg; [2018]
    Keywords : Ethanol; ethyl glucuronide; ethyl sulfate; kinetics; multiple intakes; hip flask defence; GC-FID; UPLC-MS MS;

    Abstract : The hip-flask defence is a common claim in drunkdrinking cases. In Sweden and Norway two different models are used to determinethese cases. In Sweden one blood and two urine samples taken 60 minutes apartare used for analysis. In Norway two blood samples taken 30 minutes apart areused. READ MORE

  6. 20. Leaching of Pyrrhotite from Nickel Concentrate

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Filip Abrahamsson; [2017]
    Keywords : Leaching; Pyrrhotite; Nickel Concentrate; Pentlandite; H2SO4; sulfuric acid; non-oxidative; acid leaching; Lakning; Magnetkis; Nickelkoncentrat; Pentlandit; H2SO4; svavelsyra; icke-oxidativ; syralakning;

    Abstract : Non-oxidative acid leaching of pyrrhotite from Kevitsa’s Ni-concentrate and methods to recover by-products, have been investigated. Selective dissolution of pyrrhotite (Fe1-xS, 0<x<0.25) can enrich the content of the valuable metals, such as Ni and Co, in the final concentrate and will reduce the amount of Fe and S sent to the smelters.
