  1. 21. Studies of Nuclear Matter under Extreme Conditions: Heavy-Ion Interactions at Ultra-Relativistic Energies

    Författare :Joakim Nystrand; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy-ion interactions; quark-gluon plasma; nuclear emulsion; multi-step avalanche chambers; particle production; transverse momentum distributions; intensity interferometry; nucleus-nucleus collisions; rapidity distributions; Physics; Fysik; Fysicumarkivet A:1996:Nystrand;

    Sammanfattning : The charged particle production in ultra-relativistic nucleus-nucleus collisions in the energy range 4-200 A GeV has been studied. Two different experimental techniques have been utilized: nuclear emulsions and Multi-Step Avalanche Chambers. LÄS MER

  3. 22. Topical formulations, design and drug delivery : "A dive into water"

    Författare :Abdullah Ali; Marie Lodén; Anan Yagmur; Anders Hall; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; water; topical formulations; Pickering emulsion; skin cream; drug delivery; tactile friction; sensory panel; nasal; buccal; mucosa; skin; triglycerides; ethanol; drug transport; cosmetic appeal;

    Sammanfattning : Water is a vital component regulating the properties of topical formulations and their interaction with biological barriers, such as skin and mucosa. Changing the watercontent within the frame of the pharmaceutical triangle will have a huge impact on which type of formulation, such as a cream, ointment, gel, or lotion, is formed, as well as the physical properties of the formulation.

  4. 23. Evaluation of Dust Suppressants for Gravel Roads : Methods Development and Efficiency Studies

    Författare :Karin Edvardsson; Björn Birgisson; Andrew Dawson; KTH; []
    Nyckelord :Gravel road; dust; particulate matter; PM10; horizontal dust diffusion; deteriorations; maintenance; dust control; dust suppressants; efficiency; application rate; leaching; residual concentration; seasonal variations; salt solution; solid salt; calcium chloride; magnesium chloride; lignosulphonate; polysaccharide sugar ; bitumen emulsion; rape oil; starch; surfactant; mesa; clay; fine material content;

    Sammanfattning : Approximately 75 percent (300 000 km) of the total Swedish road network and 20 percent(20 000 km) of the national road network consists of gravel roads. One of the most significantproblems associated with gravel roads is traffic-generated dust emission, which contributes tothe deterioration of the road surface and acts as a major source of particulate matter releasedinto the atmosphere, thereby involving public economics, road safety, human health, andenvironmental quality.

  5. 24. Salting-out of Colloidal Latex Particles Grafted with Poly(ethylene glycol)

    Författare :Kristin Jonsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEG; fluorinated colloids; monodisperse spheres; steric stability; emulsion polymerization; SAXS; crosslinking; salting-out; interfacial tension; SANS;

    Sammanfattning : Colloidal particles dispersed in a medium are important both in nature and in industry. The stability of colloidal particles is determined by the interactions between them and can be improved by steric stabilization. There is no conclusive understanding of how these sterically stabilized particles become unstable. LÄS MER

  7. 25. Perfluorocarbon microdroplets stabilized by cellulose nanofibers : Toward ultrasound-mediated diagnostics and therapy

    Författare :Ksenia Loskutova; Dmitry Grishenkov; Anna Justina Svagan; Gaio Paradossi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; acoustic droplet vaporization; phase-change contrast agent; Pickering emulsion; cellulose nanofiber; Ultraljud; akustisk droppförångning; kontrastmedel med fasförändring; Pickeringemulsion; cellulosananofiber; Teknik och hälsa; Technology and Health;

    Sammanfattning : Ultrasound contrast agents consist of gas-filled micrometer-sized bubbles that are injectedinto the blood stream. Ultrasound contrast agents are an invaluable tool for ultrasound imaging of the cardiac muscle and highly vascularized structures such as kidneys and the liver. LÄS MER
