    Nyckelord :amputation; complications; diabetes mellitus; diabetic foot ulcers; documentation; education; healing; home care; neuropathy; nursing; nursing process; peripheral vascular disease; pressure ulcer; prevention; RCT;

    Sammanfattning : Amputation in patients with diabetes mellitus preceded by a foot ulcer is a serious complication. Patients with the highest risk of developing a foot ulcer are often found in home nursing settings. LÄS MER

  4. 3. Mössbauer Spectroscopy of Meteoritic and Synthetic Fe-Ni Alloys

    Författare :Yassir Ahmed Mohamed Abdu; Hans Annersten; Tore Ericsson; Johan Linden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Meteorites; Tetrataenite; Antitaenite; Mössbauer spectroscopy; Mechanical alloying; Fe-Ni alloys; High pressure; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : This thesis reports on the results of investigating Fe-containing minerals in meteorites, with focus on Fe-Ni minerals and their magnetic properties, along with some synthetic Fe-Ni analogues. The New Halfa meteorite, which fell in Sudan 1994, has been studied using Mössbauer spectroscopy, X-ray diffraction, and electron microprobe analysis techniques, and classified as an ordinary L-type chondrite of petrologic type 4.

  5. 4. Magnetotransport Measurements of Ni Thin Films

    Författare :Shawn Alexander Boye; Peter Lazor; Hans Annersten; Per Nordblad; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; magnetoresistance; Hall effect; diamond anvil cell; magnon scattering; band ferromagnetism; nickel; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : This thesis presents transverse magnetoresistance (MR) and Hall resistivity measurements of nickel thin films at temperatures between 280 and 455 K and pressures up to 6 GPa. An experimental system was developed for conducting precise magnetotransport measurements using the current reversal and van der Pauw techniques in combination with a 10 T superconducting magnet.

  7. 5. Diagenesis and Reservoir-Quality Evolution of Paralic, Shallow Marine and Fluvio-lacustrine Deposits : Links to Depositional Facies and Sequence Stratigraphy

    Författare :Osama Ahmed Hlal; Sadoon Morad; Hans Annersten; J. Marcelo Ketzer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sandstone; Diagenesis; paralic; shallow marine and fluvio-lacustrine; reservoir quality; sequence stratigraphy; Solid earth geology and petrology; Berggrundsgeologi och petrologi;

    Sammanfattning : Linking diagenesis to depositional facies and sequence stratigraphy enables better prediction of spatial and temporal distribution of diagenetic alterations, and thus of evolution of reservoir quality in sandstones. This thesis demonstrates that employing this approach is possible because depositional facies and sequence stratigraphy can provide useful information on parameters controlling the near-surface diagenesis, such as changes in: (i) pore-water chemistry, (ii) residence time of sediments under certain geochemical conditions, (iii) detrital composition and proportion of extra- and intra-basinal grains, and (iv) types and amounts of organic matter.
