  2. 16. Crystallography in Four Dimensions : Methods and Applications

    Author : Gunilla Carlsson; Janos Hajdu; Dieter Oesterhelt; Vilmos Fülöp; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; horseradish peroxidase; redox reactions; X-ray crystallography; haem catalysis; molecular movies; radiation damage; Molekylär biofysik; Molecular biophysics; Molekylär biofysik;

    Abstract : The four-electron reduction of dioxygen to water is the most exothermic non-photochemical reaction available to biology. A detailed molecular description of this reaction is needed to understand oxygen-based redox processes. Horseradish peroxidase (HRP) is a haem-containing redox enzyme capable of catalysing the reduction of dioxygen to water. READ MORE

  4. 17. Computer Vision for Traffic Surveillance Systems : Methods and Applications

    Author : Saleh Javadi; Mattias Dahl; Michael Cree; Blekinge Tekniska Högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Intelligent transportation systems; ITS; Computer visions systems; Systemteknik; Systems Engineering;

    Abstract : Computer vision solutions play a significant role in intelligent transportation systems (ITS) by improving traffic flow, safety and management. In addition, they feature prominently in autonomous vehicles and their future development. The main advantages of vision-based systems are their flexibility, coverage and accessibility. READ MORE

  5. 18. Nitric oxide and extravasation in endotoxaemia : an experimental study

    Author : Kerstin Metcalf; Mikael Bodelsson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background: Despite advances in intensive care the mortality of patients in septic shock is still high. In early stages the condition is characterised by circulatory failure that is a consequence of myocardial depression, vasodilatation with decreased sensitivity to catecholamine stimulation and increased loss of protein and fluid from the circulation.

  6. 19. Exploring Intestinal Ischemia : An experimental study

    Author : Rolf Fröjse; Conny Arnerlöv; Ola Winsö; Stefan Lehtipalo; Eric Wahlberg; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; gastrointestinal tonometry; continuous; pig; pHi; intestinal ischemia; intestinal vascular bed; lactate; tissue oxygen tension; microdialysis; dopexamine; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Background and aims: Unrecognized intestinal mucosal ischemia in severely ill patients may trigger development of multiple organ failure. Such ischemia can be evaluated by intraluminal tonometry reflecting mucosal PCO2 and intramucosal pH (pHi). READ MORE

  7. 20. Single Phase Convective Heat Transfer with Nanofluids : An Experimental Approach

    Author : Ehsan Bitaraf Hgahighi; Björn E. Palm; Elena V. Timofeeva; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofluid; convective heat transfer; thermal conductivity; viscosity; heat transfer coefficient; performance; pumping power; Reynolds number; shelf stability;

    Abstract : Nanofluids (NFs) are engineered colloids of nanoparticles (NPs) dispersed homogenously within base fluids (BFs). Due to the presence of NPs, the thermophysical and transport properties of BFs are subject to change. READ MORE
