  1. 1. Advances in DNA Detection on Paper Chips

    Författare :Yajing Song; Olof Emanuelsson; Mats Nilsson; Aman Russom; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA detection; active filter papers; visualization; throughput; fluorescence; superparamagnetic beads; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

    Sammanfattning : DNA detection has an increasing importance in our everyday lives, with applications ranging from microbial diagnostics to forensic analysis. Currently, as the associated costs decrease, DNA diagnostic techniques are routinely used not only in research laboratories, but also in clinical and forensic practice. LÄS MER

  2. 2. Mechanisms of transendothelial and tissue transport in the peritoneum. Experimental studies on rat

    Författare :Bert-Inge Rosengren; Njurmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nefrologi; Urologi; hyaluronan; interstitium; blood flow; rat; pore; inhibition; temperature; peritoneal dialysis; permeability; capillary; protein; passive; active; transport; transcytosis; vesicle; Urology; nephrology; small solute;

    Sammanfattning : In the present thesis, the quantitative role of active transport (transcytosis) in bulk transvascular protein movement in vivo was evaluated. Using chemical transcytosis inhibition (N-ethylmaleimide (NEM) and filipin), we were able to show that NEM actually increases endothelial permeability to macromolecules, probably as a result of unspecific toxic action on endothelial cells.

  4. 4. Low Voltage CMOS Radio Receiver Front-End Design

    Författare :Fred Tillman; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; Elektronik; Electronics; Elektronik och elektroteknik; Electronics and Electrical technology; Polyphase Filter; Quadrature Signals; Nonlinearity; Distortion; Passive Mixer; Mixer; Low Noise Amplifier; CMOS; Front-End; Low Voltage; Radio; Receiver;

    Sammanfattning : The mass production of integrated circuits for digital electronics has made CMOS technology the most frequently used IC process today. Thanks to the large production volume, CMOS has increasingly become the most cost efficient technology of choice, and the fast development of small, high speed CMOS devices has made the technology feasible for many RF applications.

  5. 5. Single Phase Active Power Factor Correction Converters - Methods for Optimizing EMI, Performance and Costs

    Författare :Supratim Basu; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna Factor; Diode Recovery Time; Harmonic currents; EMI; Quasi Park; Snap Factor; PFC;

    Sammanfattning : In this thesis, front-end solutions with single-phase power factor correction (PFC) capability are studied. The reduction of current harmonics using various PFC techniques is investigated and related to the EN 61000-3-2 standard. LÄS MER
