  2. 6. Construction of force measuring optical tweezers instrumentation and investigations of biophysical properties of bacterial adhesion organelles

    Author : Magnus Andersson; Ove Axner; Lene Broeng Oddershede; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optical tweezers; biological physics; unfolding; Escherichia coli; force measurements; energy landscape; dynamic force spectroscopy; manipulation; polymers; pili; Physics; Fysik;

    Abstract : Optical tweezers are a technique in which microscopic-sized particles, including living cells and bacteria, can be non-intrusively trapped with high accuracy solely using focused light. The technique has therefore become a powerful tool in the field of biophysics. READ MORE

  4. 7. Intrasynovial flexor tendon injuries and repair

    Author : Sara Edsfeldt; Monica Wiig; Kenneth Jonsson; Lars Adolfsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Complications after surgical repair of intrasynovial flexor tendon injuries in the hand occur despite advanced suture techniques and structured postoperative rehabilitation regimens. Early controlled tendon mobilization prevents adhesion formations and improves tendon healing as well as digit range of motion. READ MORE

  5. 8. Topics in Modeling, Control, and Implementation in Automotive Systems

    Author : Magnus Gäfvert; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; robotteknik; Automatiska system; control engineering;

    Abstract : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. READ MORE

  6. 9. Adhesion Mechanisms of Bacterial Spores to Solid Surfaces

    Author : Ulrika Husmark; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The initial adhesion of different Bacillus spores to solid surfaces was investigated. By changing environmental parameters and studying the subsequent adhesion, conclusions have been drawn concerning the different mechanisms responsible for adhesion. Bacillus species are common microorganisms and in food industry they are common food spoilers. READ MORE

  7. 10. Roughest hour – approaches to ship hull fouling management

    Author : Dinis Oliveira; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vessel performance; fouling control coatings; hull grooming; ship resistance; adhesion strength; in-water hull cleaning; biofouling; roughness; turbulent boundary layer;

    Abstract : Submerged surfaces at sea are colonized by a high diversity of sessile (i.e. attached) life forms. As the merchant fleet capacity increases, responding to growth in demand for seaborne transport, so does the hull wetted surface area that is prone to colonization by these sessile organisms, i.
