  1. 1. The Influence of Multiple Injections on Combustion : an Experimental Investigation

    Författare :Rickard Ehleskog; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple injections; direct injected DI diesel engines; diesel sprays; emissions; Internal combustion engines; diesel combustion;

    Sammanfattning : The high fuel efficiency and torque of the diesel engine has made it the obvious choice for heavy duty applications for a long time. In addition, these characteristics of the modern super-charged HSDI diesel engine also make it very suitable and popular for car applications. LÄS MER

  3. 2. Structure and representations of certain classes of infinite-dimensional algebras

    Författare :Brendan Frisk Dubsky; Volodymyr Mazorchuk; Martin Herschend; Rolf Farnsteiner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; infinite-dimensional algebras; representation theory; category O; koszul; koszulity; injections; dihedral; preprojective; young lattice; Mathematics; Matematik;

    Sammanfattning : We study several infinite-dimensional algebras and their representation theory. In Paper I, we study the category O for the (centrally extended) Schrödinger Lie algebra, which is an analogue of the classical BGG category O. We decompose the category into a direct sum of "blocks", and describe Gabriel quivers of these blocks. LÄS MER

  4. 3. Spray Processes in Optical Diesel Engines - Air-Entrainement and Emissions

    Författare :Clement Chartier; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel; Combustion; Soot; UHC; Injections; Lift-off length; air-entrainement;

    Sammanfattning : Internal combustion engines have been an important technological field for more than a century. It has had an important impact on society through improved transportation and industrial applications. LÄS MER

  5. 4. Sterile water injections and acupuncture as treatment for labour pain

    Författare :Lena Mårtensson; Högskolan i Skövde; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Labour pain; pain relief; sterile water injections; acupuncture; survey; Obstetrics and gynaecology; Obstetrik och gynekologi; Medical sciences; Medicin; Labour pain; pain relief; sterile water injections; acupuncture; survey;

    Sammanfattning : Most women experience pain during labour. Complementary pain relief methods such as sterile water injections and acupuncture are two alternatives for the child birthing women. The lack of knowledge about the use of these methods in clinical practice creates the need to develop and evaluate them. LÄS MER

  7. 5. Patellar and Achilles tendinopathy : sclerosing injections and ultrasound guided arthroscopic shaving

    Författare :Lotta Willberg; Håkan Alfredson; Jerker Sandelin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arthroscopy; jumper’s knee; sclerosing injection; tendinopathy; ultrasound; Orthopaedics; ortopedi;

    Sammanfattning : Chronic painful tendinopathy is a common cause for elite- and recreational athletes to stop or decrease the level of their sports activity. Recent research on innervation patterns, histopathology and possible pain mechanisms in tendons has led to an increased knowledge about the chronic painful tendon. LÄS MER
