  2. 1. Anorectal malformations - their impact on early phases in life

    Author : Pernilla Stenström; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perineal ultrasonography; sphincter anatomy; pelvic floor; appendicostomy; adolesence; constipation; soiling; fecal incontinence; quality of life; anorectal malformations;

    Abstract : Abstract: Background : Anorecta l malformation s (ARM) occur in 4: 10000 newborn children with the gender distribut ion 1:1.5 females:males. The reconstruction of ARM, posterior sagiccal anorectal plasty (PSARP), was implemenred worldwide in the late 1980s and therefore the follow-ups are limited. READ MORE

  4. 2. Snow Contamination of Cars: Adhesive Particle Collisions with Exterior Surfaces

    Author : Tobias Eidevåg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; icing; particle laden flow; turbulent dispersion; premelting; sensor availability; exterior soiling; snow physics; particle resuspension; snow adhesion;

    Abstract : An ongoing challenge regarding autonomous vehicles is the obstruction of sensors by contaminants on exterior surfaces. This often occurs when driving in harsh weather conditions, where the contaminant can be, for example, water spray, dirt, or snow. READ MORE

  5. 3. Computational study of rivulets using Volume of Fluid

    Author : Tobias Tivert; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis focuses on numerical methods of soiling and some multiphase concepts related to it.The Volume of Fluid method was tested in two different test cases and showed fairly good results.The first test case was a gravity driven rivulet on an inclined plate, where it was an inlet with a constant water velocity at the beginning of the plate.

  6. 4. Bladder and bowel dysfunction in children with anorectal malformations : Blås och tarmdysfunktion hos barn med anorektala missbildningar

    Author : Helena Borg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bladder and bowel dysfunction; Anorectal malformations; Spinal cord malformation; Megarectosigmoid;

    Abstract : Background: Bowel dysfunction is seen in all children with anorectal malformations (ARMs) and is strongly related to associated anomalies commonly found in these patients. The presence of a megarectosigmoid (MRS) further contributes to chronic constipation and overflow incontinence. READ MORE

  7. 5. Aspects of Hirschsprung disease

    Author : Anna Löf Granström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hirschsprung disease (HSCR) is a congenital defect of the enteric nervous system characterized by a lack of enteric neurons in the distal hindgut. Motility disturbances in the distal colon usually lead to neonatal intestinal obstruction. The birth prevalence of HSCR has been assessed to 1 in 5,000 live births. READ MORE
