  1. 1. Isthmic spondylolisthesis in adults : a randomized controlled trial

    Författare :Hans Möller; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Isthmic spondylolisthesis, i.e. the slipping of one vertebra on another due to a defect in the pars interarticularis, is a common radiological finding in the general population and can sometimes be the source of chronic low back pain. LÄS MER

  3. 2. 1-D simulation of turbocharged SI engines : focusing on a new gas exchange system and knock prediction

    Författare :Christel Elmqvist-Möller; Hans-Erik Ångström; Daniel Håkansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spark ignited engines; 1-D flow simulation; knock; Divided Exhaust Period; turbocharged engines; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : This licentiate thesis concerns one dimensional flow simulation of turbocharged spark ignited engines. The objective has been to contribute to the improvement of turbocharged SI engines’ performance as well as 1 D simulation capabilities. Turbocharged engines suffer from poor gas exchange due to the high exhaust pressure created by the turbine. LÄS MER

  4. 3. Glacial dynamics and till genesis in hilly terrain : A study in the Tallträsk area, central-northern Sweden

    Författare :Hans Ivarsson; Mats Jansson; Per Möller; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; Physical geography; Naturgeografi;

    Sammanfattning : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. LÄS MER

  5. 4. Studies of ankle fractures : classification, epidemiology, complications and results

    Författare :Hans Juto; Per Morberg; Magnus Hultin; Michael Möller; Sari Ponzer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ankle fracture; Swedish Fracture Register; AO OTA-classification; epidemiology; venous thromboembolic event; low-molecular-weight heparin; sick leave; outcome; Orthopaedics; ortopedi;

    Sammanfattning : The ankle fracture is one of the most common fractures in adult patients and is a heterogeneous group of fractures. From the fully stable fracture on the most distal part of thefibula to severely unstable and even dislocated ankles. Patients with ankle fractures often report a good result after treatment, but a small group have persistent problems. LÄS MER

  7. 5. Deafblindness : Theory-of-mind, cognitive functioning and social network in Alström syndrome

    Författare :Hans-Erik Frölander; Claes Möller; Björn Lyxell; Erland Hjelmquist; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alström syndrome; Deafblindness; Theory-of-mind; Communication; Verbal ability; Executive functions; Working memory; Health problems; Friendship; Social network; Handikappvetenskap; Disability Research;

    Sammanfattning : This thesis addresses young adults with Alström syndrome (AS). AS causes acquired deafblindness, a severe, progressive, combined auditory and visual impairment affecting daily life and self-reliance to a degree that full participation depends on help from others and society.
