  2. 22. Testicular blood flow : methodological and functional studies in the rat

    Author : Jan-Erik Damber; Umeå universitet; []
    Keywords : ;

    Abstract : Different methods of measuring testicular blood flow in the rat were compared in an attempt to find an accurate method for measuring physiological testicular blood flow. It was found that both the Xenon- 133 clearance technique and the radioactive microsphere technique probably reflect true physiological blood flow in the testis. READ MORE

  3. 23. Modelling of Bingham Suspensional Flow : Influence of Viscosity and Particle Properties Applicable to Cementitious Materials

    Author : Annika Gram; Björn Lagerblad; Ulrich Diederichs; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Self-Compacting Concrete; SCC; Fresh concrete flow; Numerical simulation; Viscosity; Open channel flow;

    Abstract : Simulation of fresh concrete flow has spurged with the advent of Self-Compacting Concrete, SCC. The fresh concrete rheology must be compatible with the reinforced formwork geometry to ensure complete and reliable form filling with smooth concrete surfaces. READ MORE

  4. 24. Aortic valvular flow : a clinical and experimental doppler echocardiographic study

    Author : Birgitta Janerot Sjöberg; Ihlen Halfdan; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Aortic blood velocity determination by ultrasound Doppler is a safe and valuable tool when evaluating patients with heart disease. The time-course of the velocity signal can be used for detemnining left ventricular function. READ MORE

  5. 25. Ribosomes and subunits from Escherichia coli studied by asymmetrical flow field-flow fractionation

    Author : Mikael Nilsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; VHb; Vitreoscilla hemoglobin; E. coli; Escherichia coli; separation; subunits; ribosomes; Asymmetrical flow field-flow fractionation; flow FFF; optimization; biotechnological production; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis asymmetrical flow field-flow fractionation (FFF) separations of ribosomes and subunits have been studied. Ribosomal material was prepared from Escherichia coli (E. coli) cells and analyzed by the size separation technique. READ MORE
