    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nano-engineered microbubbles; SPION nanoparticles; Acoustic characterization of MBs; Fracturing mechanism of MBs; Opto-acoustics; Acoustophoresis; Physics; Fysik; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer; Teknik och hälsa; Technology and Health;

    Abstract : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.

  2. 2. Opportunity creation as a mixed embedding process A study of immigrant entrepreneurs in Sweden

    University dissertation from Jönköping : Jönköping University, Jönköping International Business School

    Author : Quang V. D. Evansluong; Högskolan i Jönköping.; [2016]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; immigrant entrepreneurship; opportunity creation; entrepreneurial opportunity; social integration; Sweden; mixed embeddedness; mixed embedding;

    Abstract : Entrepreneurial opportunities are frequently noted and addressed in the literature of immigrant entrepreneurship; however, little is known about how these entrepreneurial opportunities come into existence and how immigrant entrepreneurs create such opportunities. The purpose of this thesis is to examine why and how immigrant entrepreneurs create entrepreneurial opportunities through embedding processes in the home country and the host country. READ MORE

  3. 3. Interactions between Fe and organic matter and their impact on As(V) and P(V)

    University dissertation from Umeå : Umeå Universitet

    Author : Anneli Sundman; Umeå universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; XAS; Fe III ; As V ; P V ; natural organic matter; Fe II; III -NOM complexes; Krycklan catchment; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys;

    Abstract : Iron (Fe) speciation is important for many biogeochemical processes. The high abundance and limited solubility of Fe(III) are responsible for the widespread occurrence of Fe(III) minerals in the environment. READ MORE

  4. 4. Flutter in sectored turbine vanes

    University dissertation from Stockholm : Energiteknik

    Author : Olga V. Chernysheva; KTH.; [2004]
    Keywords : turbomachinery; aerodynamics; unsteady CFD; design; flutter;

    Abstract : In order to eliminate or reduce vibration problems inturbomachines without a high increase in the complexity of thevibratory behavior, the adjacent airfoils around the wheel areoften mechanically connected together with lacing wires, tip orpart-span shrouds in a number of identical sectors. Although anaerodynamic stabilizing effect of tying airfoils together ingroups on the whole cascade is indicated by numerical andexperimental studies, for some operating conditions suchsectored vane cascade can still remain unstable.

  5. 5. Excitons in a high magnetic field

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Alexandre V. Petrov; Uppsala universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; fysik; Physics;

    Abstract : The interaction of excitons with each other and with charged impurities has been studied in a high magnetic field when the distance between the Landau levels is greater than the Coulomb unit of energy, in the frame of the model suitable for description of Wannier excitons in semiconductors. The analytical expressions for the pair interaction potential between hydrogenlike excitons in a high magnetic field are derived for the triplet and singlet terms. READ MORE
