  2. 6. Studies on the deposition, bioavailability and systemic activity of glucocorticoids in man

    Author : Lars Thorsson; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacological sciences; systemic activity; glucocorticosteroids; lung deposition; systemic availability; inhalation; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : The local deposition, pharmacokinetics, and systemic activity of inhaled and intranasal glucocorticosteroids in different formulations and devices(ICSs) has been investigated. After nasal administration of the ICS budesonide (Bud), the systemic availability (F) was found to be significantly higher from an aqueous pump spray and from the powder inhaler Turbuhaler, than from a pressurized metered dose inhaler (pMDI), and the uptake process was slower and less complete with the pMDI formulation.

  4. 7. Cold spray Cr-coated Optimized ZIRLO claddings: an option for accident tolerant fuels

    Author : Andrea Fazi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cr coating; atom probe tomography; cold spray; accident tolerant fuel;

    Abstract : Accident tolerant fuel development has started with the aim of providing nuclear fuels able to endure severe accident conditions. Research in this field has also sparked a wave of material renewal in the nuclear industry that had being delayed for the last few decades. READ MORE

  5. 8. The rotating injector as a tool for exploring DI diesel combustion and emissions formation processes

    Author : Magnus Sjöberg; KTH; []
    Keywords : diesel spray combusion; rotating injector. Air swirl; air fuel-mixing. Soot. NO. CO; flame visualization. Chemking modeling. Soot deposition;

    Abstract : A diesel fuel injector has been modified to allow rotationaround its axis, driven by an electric motor. Injections at upto 6000 rpm from the rotating injector have been investigatedunder the influence of air swirl on one optical research engineand one optically accessible heavy-duty diesel engine.

  6. 9. Development and performance evaluation of accident-tolerant coated fuel claddings for light water reactors

    Author : Andrea Fazi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVD; oxidation; accident tolerant fuel; autoclave; cold spray; nitride coatings; Cr coating;

    Abstract : The development of accident tolerant fuel has the aim of providing nuclear fuels able to endure severe accident conditions. Research in this field has also sparked a wave of material renewal in the nuclear industry that had been delayed for the last few decades. READ MORE

  7. 10. Sources, transport and fate of perfluoroalkyl acids in the atmosphere

    Author : Jana Johansson; Ian Cousins; Tom Harner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perfluorinated alkyl acids; PFOS; PFOA; Isomers; Sources; Atmospheric transport; Sea spray; Gas-particle partitioning; Volatilisation; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Perfluoroalkyl acids (PFAAs) are man-made chemicals which have been observed in the global environment, even in locations far away from where they are emitted. These persistent substances are taken up in humans and biota and may have toxic effects. READ MORE
