  1. 21. Mechanisms of microbial-host interaction during asymptomatic bacteriuria

    Författare :Jenny Grönberg Hernandez; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asymptomatic bacteriuria; Urinary tract infection; Escherichia coli 83972; IRF3; TLR4; Evolution; host response; promoter polymorphisms; transcription; P fimbriae; Type 1 fimbriae;

    Sammanfattning : Urinary tract infections (UTIs) present an interesting and relevant model for studying microbial adaptation. After establishing significant numbers, the bacteria either cause severe disease, or an asymptomatic carrier state resembling the normal flora at other mucosal sites. LÄS MER

  3. 22. On the Properties of Some Strongly Correlated Systems - Analytical and Numerical Studies

    Författare :Jurij Smakov; KTH; []
    Nyckelord :mean field theory; magnetic multilayers; Curie temperature; compensation temperature; scanning tunneling microscopy; tunneling; superconductivity; local density of states; Josephson effect; tunneling Hamiltonian formalism; impurities in superconducto;

    Sammanfattning : This thesis is dedicated to analytical and numerical studiesof a few models of strongly correlated systems and thedevelopment of techniques for such studies. The common name"strongly correlated" refers to systems in which theinteractions (correlations) between the constituent particleslead to nontrivial properties, such as various types ofmagnetism, superconductivity, and exotic phases.

  4. 23. Tactile sensing of prostate cancer : a resonance sensor method evaluated using human prostate tissue in vitro

    Författare :Ville Jalkanen; Olof Lindahl; Britt Andersson; Tomas Jansson; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tactile resonance sensor; prostate tissue; prostate cancer; stiffness; density; elastic; variations; tissue histology; Medical engineering; Medicinsk teknik;

    Sammanfattning : Prostate cancer is the most frequent type of cancer in men in Europe and the USA. The methods presently used to detect and diagnose prostate cancer are inexact, and new techniques are needed. LÄS MER

  5. 24. Improving the understanding of cloud radiative heating

    Författare :Erik Johansson; Abhay Devasthale; Michael Tjernström; Annica M. L. Ekman; Robert Pincus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; clouds; radiative effects; upper troposphere-lower stratosphere; atmospheric circulation; remote sensing; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Clouds play an essential role in regulating Earth’s radiation budget by reflecting and absorbing energy at different spectra. As they interact with radiation, they can radiatively heat or cool the adjacent atmosphere and the surface. LÄS MER

  7. 25. On the Spray Forming of Metals, the Formation of Porosity and the Heat Evolution during Solidification

    Författare :José Tinoco; KTH; []
    Nyckelord :Thermal analysis; Nodular Cast Iron; Inconel 625; CFD; Flow Assesment; Multiphase Flow; Spray Deposition; Microporosity; Superalloys;

    Sammanfattning : This thesis deals with the heat evolution duringsolidification and its relation to the formation of porosity.It intends to improve the current understanding of theformation of porosity in cast materials with special interestin nodular cast iron and the spray forming process.
