  1. 1. Type-II interband quantum dot photodetectors

    Författare :Oscar Gustafsson; Mattias Hammar; Wenquan Ma; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodetector; quantum dot; infrared; MOVPE; thermal imaging; type-II; photoluminescence; III V; InSb; InGaSb; InAs; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Photon detectors based on single-crystalline materials are of great interest for high performance imaging applications due to their low noise and fast response. The major detector materials for sensing in the long-wavelength infrared (LWIR) band (8-14 µm) are currently HgCdTe (MCT) and AlGaAs/GaAs quantum wells (QW) used in intraband-based quantum-well infrared photodetectors (QWIPs).

  3. 2. Dendritic cell presentation of type II collagen

    Författare :Meirav Holmdahl; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; chromosome 2; arthritis; proteases; antigen presentation; Dendritic cell; type II collagen;

    Sammanfattning : Type II collagen (CII) is the main protein component of cartilage and immune recognition of CII plays a critical role for the development of collagen induced arthritis (CIA), a widely used animal model for rheumatoid arthritis (RA). Antigen presentation is an important requirement for the immune response, the more efficient presentation of the antigen the better tolerance will be induced and thereby protect against arthritis.

  4. 3. Tripeptidyl-Peptidase II : Structure, Function and Gene Regulation

    Författare :Ann-Christin Lindås; Birgitta Tomkinson; Mikael Widersten; Ralf Morgenstern; Uppsala universitet; []
    Nyckelord :Biochemistry; gene regulation; protein expression; enzyme kinetics; tripeptidyl-peptidase II; proteasome; intracellular protein degradation; exopeptidase; Biokemi;

    Sammanfattning : The protein degradation process is of vital importance for the cell to maintain cellular functions. An important enzyme in this process is the multimeric tripeptidyl-peptidase II (TPP II). It removes tripeptides from a free N-terminus of the substrates. LÄS MER

  5. 4. Sobolev-Type Spaces : Properties of Newtonian Functions Based on Quasi-Banach Function Lattices in Metric Spaces

    Författare :Lukáš Malý; Anders Björn; Jana Björn; Tomas Sjödin; Andrea Cianchi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Newtonian space; Sobolev-type space; metric measure space; upper gradient; Sobolev capacity; Banach function lattice; quasi-normed space; rearrangement-invariant space; maximal operator; Lipschitz function; regularization; weak boundedness; density of Lipschitz functions; quasi-continuity; continuity; doubling measure; Poincaré inequality;

    Sammanfattning : This thesis consists of four papers and focuses on function spaces related to first-order analysis in abstract metric measure spaces. The classical (i.e., Sobolev) theory in Euclidean spaces makes use of summability of distributional gradients, whose definition depends on the linear structure of Rn. LÄS MER

  7. 5. Angiotensin II Receptors in the Human Coronary Circulation and in Heart Failure

    Författare :Emil Pantev; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Heart Failure; Human Coronary Arteries; Angiotensin II; AT receptors;

    Sammanfattning : Angiotensin II (Ang II) is a potent vasoconstrictor that is implicated in the pathogenesis of hypertension, heart failure and atherosclerosis. In this thesis, the efficacy and safety of Ang II receptor blockers (ARB) were evaluated. LÄS MER
