  2. 11. Radiological evaluation of esophageal function in dysphagia with special emphasis on achalasia

    Author : Mats Andersson; Göteborgs universitet; []
    Keywords : Achalasia; Dysphagia; Radiography; Barium esophagogram; Reproducibility of findings; Observer variation; Laparoscopic myotomy; Balloon dilatation; Esophageal neoplasms;

    Abstract : In idiopathic achalasia, degeneration of the inhibitory innervation of the esophageal smooth muscle results in absence of primary peristalsis and in incomplete relaxation of the lower esophageal sphincter (LES). All treatments for achalasia aim at reducing the pressure gradient across the LES, thus facilitating esophageal emptying by gravity. READ MORE

  4. 12. Hand function in children and in persons with neurological disorders : aspects of movement control and evaluation of measurements

    Author : Elisabeth Svensson; Charlotte Häger-Ross; Birgitta Lindmark; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebellum; disability; hand function; hereditary motor and sensory neuropathies; latency; motor control; reactive control; reproducibility; sensation; strength; Physiotherapy; Sjukgymnastik fysioterapi;

    Abstract : Hand function is of great importance in the many daily activities that require well-coordinated hand and arm movements. Measurement of hand function is an essential element in the rehabilitation process, in order to facilitate medical diagnosis and determine developmental stages, functional levels, and the efficacy of treatment interventions.

  5. 13. The Mystery of Inequality : Essays on Culture, Development, and Distributions

    Author : Olle Hammar; Daniel Waldenström; Niklas Bengtsson; Ingvild Almås; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inequality; Culture; Development; Economics; Nationalekonomi;

    Abstract : Essay I (with Daniel Waldenström): We estimate trends in global earnings dispersion across occupational groups by constructing a new database that covers 68 developed and developing countries between 1970 and 2018. Our main finding is that global earnings inequality has fallen, primarily during the 2000s and 2010s, when the global Gini coefficient dropped by 15 points and the earnings share of the world’s poorest half doubled.

  6. 14. Studies of the fibre direction and local bending stiffness of Norway spruce timber : for application on machine strength grading

    Author : Min Hu; Marie Johansson; Mats Ekevad; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; digital image correlation; diving angle; fibre angle; grain angle; indicating property; laser scanning; modulus of elasticity; tracheid effect; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Machine strength grading is a production process in the sawmill industry used to grade sawn timber boards into different strength classes with specific characteristic values of the bending strength, modulus of elasticity (MOE) and density. These properties are called grade determining properties. READ MORE

  7. 15. Adhesion and Nanotribology of Biofibres

    Author : Hiroyasu Mizuno; Mark Rutland; Nicholas Spencer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The fibre probe atomic force microscope is developed, which allows direct measurement of force and friction between single fibres at the nanoscale under various conditions. In this work, polyester and human hair fibres were used as being representative of synthetic and animal fibre. READ MORE
