  1. 6. Resistance breathing with PEP and CPAP : effects on respiratory parameters

    Författare :Maria Sehlin; Ola Winsö; Karin Wadell; Fredrik Öhberg; Monika Fagevik Olsèn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chest physiotherapy; breathing exercises; PEP; CPAP; airway pressure; airflow; threshold resistor; flow resistor; inspiratory capacity; Borg CR10;

    Sammanfattning : Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. LÄS MER

  3. 7. Adsorption of pinosylvin onto the structure of wood : mechanism and adsorption parameters

    Författare :Ildiko Mohammedne Ziegler; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Pinosylvin and polyhydroxybenzene derivatives are natural components of wood, known for their fungicidal/fungistatic properties. These components were used as adsorbates in the present investigation. LÄS MER

  4. 8. Parameters optimization of oil well drilling operation

    Författare :Ali Darwesh; Thorkild Maack Rasmussen; Nadhir Al-Ansari; Daniel Ask; Bernt Sigve Aadnøy; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bazian Block; Kurdistan; Iraq; Optimization; Drilling Parameters; Rate of Penetration; Wiper trips; Kicks; Pay zone; Bourgoyne and Young model; Exploration Geophysics; Prospekteringsgeofysik;

    Sammanfattning : In the beginning of 2005, the ministry of natural resources in the Kurdistan region of Iraq dividedits territory into more than 50 oil blocks based on geological setting. These oil blocks were awardedlater to different international oil companies for oil investments based on Production SharingContracts (PSCs). LÄS MER

  5. 9. A parametric grammar of Seediq

    Författare :Arthur Holmer; Allmän språkvetenskap; []

    Sammanfattning : Seediq is an Austronesian language spoken in Taiwan. It has several characteristics which are typologically unusual but typical for Austronesian languages. VOS word order, subject-focus (i.e. LÄS MER

  7. 10. Acceleration of Compressible Flow Simulations with Edge Using  Implicit Time Stepping

    Författare :Evelyn Otero; Arthur Rizzi; Richard P. Dwight; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressible CFD; Convergence Acceleration; Implicit Time-Stepping; LU-SGS; Upwind Type Dissipation; Line-implicit; Ordering; Parallelization; Parameters; Multigrid;

    Sammanfattning : Computational fluid dynamics (CFD) is a significant tool routinely used indesign and optimization in aerospace industry. Often cases with unsteadyflows must be computed, and the long compute times of standard methods hasmotivated the present work on new implicit methods to replace the standardexplicit schemes. LÄS MER
