  1. 1. Konstitueringen av ett vetenskapligt begrepp : Exemplet - det manliga klimakteriet

    Författare :Adam Droppe; Nora Räthzel; Björn Söderfeldt; Thomas Brante; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; andropause; sociology of science; male gender; testosterone; profession of medicine; big pharma; research policy; feminism; development of science; Late Onset Hypogonadism; the aging male; andrology; andropaus; vetenskapssociologi; testosteron; medicinsk profession; läkemedelsindustri; feminism; forskningspolitik; andrologi; manligt genus;

    Sammanfattning : How are new scientific concepts of illnesses and disorder formed? The last fifty years have seen a dramatic increase in new diagnoses incorporated into medical manuals. The concept of the male menopause, or the andropause diagnosis, is suitable for studying how medical knowledge is produced, since it has alternated between being and not being part of the acknowledged medical knowledge since the beginning of the 19th century, when it was originally launched.

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; perpendicular magnetic anisotropy; tilted-polarizer; spintronics; STT; MTJ; pseudospin-valve; STO; ST-FMR; magnonics; magnetic droplet; droplet nucleation; droplet annihilation; vinkelrät magnetisk anisotropi; lutande polarisator; spinntronik; STT; MTJ; pseudospinnventil; STO; ST-FMR; magnonics; magnetisk droppe; nukleering av droppe; anihilering av droppe.; Physics; Fysik;

    Sammanfattning : Spin-torque transfer (STT) effects have brought spintronics ever closer to practical electronic applications, such as MRAM and active broadband microwave spin-torque oscillator (STO), and have emerged as an increasingly attractive field of research in spin dynamics. Utilizing materials with perpendicular magnetic anisotropy (PMA) in such applications offers several great advantages such as low-current, low-field operation combined with high thermal stability.

  4. 4. Detailed simulations of droplet evaporation

    Författare :Giandomenico Lupo; Christophe Duwig; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; droplet; evaporation; phase change; multicomponent; immersed boundary; droppe; förångning; fasövergång; multikomponent; nedsånkt rand;

    Sammanfattning : Droplet evaporation (and condensation) is one of the most common instancesof multiphase flow with phase change, encountered in nature as well as intechnical and industrial applications. Examples include falling rain drops, fogsand mists, aerosol applications like electronic cigarettes and inhalation drugdelivery, engineering applications like spray combustion, spray wet scrubbing orgas absorption, spray drying, flame spray pyrolysis.

  5. 5. Synthesis of Polyhydroxylated Surfactants : Comparison of Surfactant Stereoisomers and Investigation of Haemolytic Activity

    Författare :Kristina Neimert-Andersson; Peter Somfai; Krister Holmberg; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Polyhydroxy surfactants; Sugar surfactants; Dihydroxylation; Metathesis; Langmuir monolayers; Chiral discrimination; Haemolysis; Organic chemistry; Organisk kemi;

    Sammanfattning : I den här avhandlingen har vi studerat hur man kan göra nya tensider. En tensid är en speciell molekyl som har förmågan att lösa sig i både vatten och olja. Man kan göra följande experiment hemma: Fyll en glasburk till hälften med vatten och tillsätt en droppe matolja. LÄS MER
