  2. 21. A Novel Miniaturised Dynamic Hollow-Fibre Liquid-Phase Micro-Extraction Method for Xenobiotics in Human Plasma Samples

    Author : Helena Hansson; Ulrika Nilsson; Bo Karlberg; Peter Haglund; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sample clean-up; human blood plasma; hollow-fibre liquid phase microextraction; supported liquid membrane extraction; SLM; HF-LPME; sample preparation; bioanalysis; liquid-liquid extraction; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Bioanalytical chemistry is a challenging field, often involving complex samples, such as blood, plasma, serum or urine. In many applications, sample cleanup is the most demanding and time-consuming step. READ MORE

  4. 22. Composite Columns of Hollow Steel Sections Filled with High Strength Concrete

    Author : Marianne Grauers; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In the design of buildings today, great effort is made to increase the structural flexibility. This has resulted in a demand for columns with reduced cross sections. To achieve a high load bearing capacity with a small cross sectional area, it is worthwhile to study the possibility of utilizing high strength concrete and composite effects. READ MORE

  6. 24. Habitat requirements and preservation of the beetle assemblages associated with hollow oaks

    Author : Nicklas Jansson; Per Milberg; Karl-Olof Bergman; Simon Grove; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : One of the most endangered assemblages of species in Europe is saproxylic beetles associated with old trees. To be able to conserve these species there is a need of developing methods to survey the fauna and to evaluate the conservation value of different oak habitats, develop instruments for landscape planning and detailed knowledge of species habitat requirements.

  7. 25. Experimental Studies on CO2 Capture Using Absorbent in a Polypropylene Hollow Fiber Membrane Contactor

    Author : Yuexia Lu; Jinyue Yan; Erik Dahlquist; Umberto Desideri; Mälardalens högskola; []
    Keywords : CO2 capture; Simultaneous removal of CO2 and SO2; Hollow fiber membrane contactor; Membrane gas absorption; Partial wetting; Surface modification; CO2-avskiljning; samtidig avskiljning av CO2 och SO2; ihålig fiber; membran; gas absorption; vätning; ytmodifiering; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In recent years, membrane gas absorption technology has been considered as one of the promising alternatives to conventional techniques for CO2 capture due to its favorable mass transfer performance. As a hybrid approach of chemical absorption and membrane separation, it exhibits a number of advantages, such as operational flexibility, compact structure, high surface-area-to-volume ratio, linear scale up, modularity and predictable performance.
