  1. 1. Wireless Communication with Medical Implants: Antennas and Propagation

    Författare :Anders J Johansson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical implant communication; electromagnetic propagation; biomedical telemetry; antennas in matter; MICS; Electronics; Elektronik;

    Sammanfattning : With the increased sophistication of medical implants, there is a growing need for flexible high-speed communication with the implant from outside the body. Today the communication is done by an inductive link between the implant and an external coil at a low carrier frequency. LÄS MER

  3. 2. Streptococcal M protein and human C4BP

    Författare :Jenny J Persson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; Medicin människa och djur ; Medicine human and vertebrates ; human C4BP; M protein; antigenic variation; sequence variability; Streptococcus pyogenes; innate immunity;

    Sammanfattning : Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. LÄS MER

  4. 3. Structural Properties of Palladium-Manganese Alloys

    Författare :Alexander J Jaworowski; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transition metal; structure; growth; adsorption; core level photoemission. scanning tunneling microscopy; fourier-transform infrared spectroscopy; Manganese; Palladium; Rhodium; Molybdenum; NO; CO; alloy; O; Physics; Fysik; Semiconductory physics; Halvledarfysik; Fysicumarkivet A:2001:Jaworowski;

    Sammanfattning : Structural properties of adsorbed overlayers on well-defined single crystals and of Palladium-Manganese surface alloys formed on Pd(100) have been investigated using synchrotron-based photoemission, scanning tunneling microscopy and Fourier-transform infrared spectroscopy. The experimental valence electronic structure of PdMn systems on Pd(100) is compared to density functional calculations (DFT). LÄS MER

  5. 4. General Practitioners' Conceptions of Depressive Disorders: Associations with regional sales of antideprssive drugs

    Författare :Stig J Andersson; Allmänmedicin och samhällsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical training; General practice; questionnaire survey; qualitative interview study; antidepressive drug sales; depressive disorders; conceptions; General practitioner; Allmän medicinsk utövning; medicinsk utbildning;

    Sammanfattning : This thesis emanates from considerations about the inter-regional variation of the sales of antidepressive drugs, and how general practitioners may contribute to that variation. The thesis comprises two data collections utilized for five separate studies. LÄS MER

  7. 5. Influence of Internal Diffusional Limitations on the Performance of an Immobilized Enzyme in Organic Medium

    Författare :Raúl J Barros; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; internal diffusional; acetonitrile medium; Immobilized a-chymotrypsin; kinetically controlled peptide synthesis; Bioteknik;

    Sammanfattning : The influence of mass-transfer limitations on the performance of immobilized a-chymotrypsin operating in acetonitrile medium has been investigated. The enzyme was immobilized by deposition on various porous carrier materials such as celite, polyamides of different particle sizes, controlled-pore glasses, polypropylene or polyacrylamides. LÄS MER
