  1. 1. Calorimetric methods for the study of fungi on building materials

    Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fungal growth; fungal activity; ergosterol; humidity; temperature; calorespirometry; oxygen; mätmetoder; röta; svamp; byggmaterial; påväxt; kalorimetri; microcalorimetry; isothermal calorimetry; Fungi; building materials; mould; Serpula lacrymans; rot fungi;

    Sammanfattning : The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. LÄS MER

  3. 2. Measurement of Self-Heating of Biomass Pellets using Isothermal Calorimetry

    Författare :Ida Larsson; Karin Granström; Anders Lönnermark; Per Blomqvist; Patrick van Hees; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal calorimetry; biomass pellets; wood pellets; self-heating; reactivity; screening test; isoterm kalorimetri; pellets; biomassa; självuppvärmning; reaktivitet; screeningtest; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Self-heating in storage facilities of biomass pellet can lead to spontaneous combustion. This has resulted in many fires over the years, causing both financial and environmental losses.In order to assess the risk for spontaneous combustion of biomass pellets during storage, it is important to know how prone the fuel is to self-heating, i.e. LÄS MER

  4. 3. Spin ice under uniaxial pressure and magnetic frustration in garnets

    Författare :Richard Edberg; Patrik Henelius; Santiago A. Grigera; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetism; fysik; spin is; frustrerad magnetism; värmekapacitet; heat capacity; spin ice; physics; magnetism; Material and Nano Physics; Material- och nanofysik;

    Sammanfattning : Frustration is the inability to simultaneously satisfy all interactions. The interest in magnetic frustration has grown during the last decades. The research has among other findings been promoted by the discovery of spin ice which is a frustrated magnetic compound with an exotic ground state and unusual excitations. LÄS MER

  5. 4. Carrot Juice Processing - Effects on Various Quality Aspects

    Författare :Charlotte Alklint; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modified atmosphere; shelf-life; accelerated storage; isothermal calorimetry; pressing; expression method; colour; dietary fibre; carotene; composition; carrot pomace; carrot juice; carrot pulp; acidification; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Carrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. LÄS MER

  7. 5. Drugs and polymers in dissolving solid dispersions : NMR imaging and spectroscopy

    Författare :Carina Dahlberg; István Furó; Anna Millqvist-Fureby; Michael Schuleit; Jadwiga Tritt-Goc; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical chemistry; Fysikalisk kemi; Surface and colloid chemistry; Yt- och kolloidkemi; PHARMACY; FARMACI;

    Sammanfattning : The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioavailability of the drug.
