  1. 1. Flow injection systems for process analytical chemistry

    University dissertation from Umeå : Umeå Universitet

    Author : Ingrid Lukkari; Umeå universitet.; [1995]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flow injection; Sequential injection; Process analytical chemistry; Multivariate calibration; Sensor injection; Gas-diffusion; Sample clean-up;

    Abstract : Flow injection systems have great potential for sample handling and analysis in process analytical chemistry. The flexibility and versatility of flow injection manifolds can he utilized in specific applications of sample conditioning and analysis. READ MORE

  2. 2. Turbulent Boundary Layer Separation and Control

    University dissertation from Stockholm : KTH

    Author : Ola Lögdberg; KTH.; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow control; adverse pressure gradient APG ; flow separation; vortex generators; jet vortex generators; pulsed jet vortex generators; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Abstract : Boundary layer separation is an unwanted phenomenon in most technical applications, as for instance on airplane wings, ground vehicles and in internal flow systems. If separation occurs, it causes loss of lift, higher drag and energy losses. It is thus essential to develop methods to eliminate or delay separation. READ MORE

  3. 3. Flow-induced Surface Defects and Ageing Behaviour of Injection-moulded Polymers

    University dissertation from Stockholm : KTH

    Author : Giovanna Iannuzzi; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PP; surface defects; flow marks tiger stripes ; ageing; Injection moulding; ABS; rheological properties; degradation; surface topography; discolouration;

    Abstract : Injection moulding is one of the most commonly used manufacturing methods for the production of polymer-based components such as car bumpers and other automotive details. The surface appearance of these products is of great importance since it is directly connected to the perceived quality. READ MORE

  4. 4. Sampling, sample treatment, assay and real time monitoring of biotechnological processes using an integrated flow-injection system

    University dissertation from Stockholm : KTH

    Author : Mohammad Mazlomi; Lund University.; Lunds universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioprocess; Sampling; Sample treatment; On-line monitoring; Real time monitoring; Flow injection; Immunoassay; Fermentation;

    Abstract : Microorganisms can be used for production of pharmaceutical substances. With the introduction of gene technology, it is possible to transfer information from one organism to the other, thereby making the receiving organism capable of producing substances that it did not so before. This development is very important for e.g. READ MORE

  5. 5. Flow, expansion and processing behaviours of gas-containing filled polyethylene

    University dissertation from Stockholm : KTH

    Author : Nabil Khoshaba; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; flow rate; critical pressure; injection moulding; expansion kinetics; fillers; rheological properties; foaming; composite materials; partial pressure; capillary viscometry; Blowing agent;

    Abstract : The utilization of fillers in polymeric materials has exhibited a substantial growth during the last decades. Chalk (calcium carbonate) and glass fibres are two common examples of such fillers. These fillers/reinforcing elements are used in order to reduce the cost of material and change its physical (mechanical) properties. READ MORE
