  1. 21. A New Shoulder for the THOR Dummy Intended for Oblique Collisions

    Författare :Fredrik Törnvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shoulder; Shoulder range-of-motion; Volunteers; Kinematics; Biofidelity; Post Mortem Human Subjects; THOR; Crash test dummy; Oblique collision;

    Sammanfattning : Offset and oblique frontal car collisions represent a type of crash in which severe and fatal injuries frequently occur. This indicates the importance of having protective systems in vehicles for these types of collisions. LÄS MER

  3. 22. Towards strategic development of maintenance and its effects on production performance : A hybrid simulation-based optimization framework

    Författare :Gary Linnéusson; Amos H. C. Ng; Tehseen Aslam; Daniel Tesfamariam Semere; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strategic development; maintenance behavior; maintenance management; sustainable change; tradeoff optimization; system dynamics; discrete event simulation; problem structuring; multi-objective optimization; decision support; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : Managing maintenance in manufacturing within an economical short-termism framework and taking the consequential long-term cost effects into account is hard. The increasing complexity of managing maintenance and its impact on the business results calls for more advanced methods to support long-term development through effective activities in the production system environment.

  4. 23. ABA and chromatin remodelling regulate the activity-dormancy cycle in hybrid aspen

    Författare :Anna Petterle; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : One of the most important survival strategies plants have evolved is the cessation of growth and development of dormancy in response to the seasonal changes. Apical meristems of deciduous woody plants living in temperate and boreal zones undergo a yearly cycle between an active and a dormant state, which allows them to protect the meristem and avoid damage provoked by extremes of low temperatures during the winter.

  5. 24. Measurement of shear force, temperature profiles and fibre development in mill-scale TMP refiners

    Författare :Hans-Olof Backlund; FSCN - Fibre Science and Communication Network; []
    Nyckelord :Shear force; Tangential force; Temperature profile; Thermomechanical pulping;

    Sammanfattning : Two different force sensors have been developed for tangential forcemeasurements in commercial TMP refiners, one is based on the use of piezoelectricsensors and the other on strain gauges. The measurements are used to learn moreabout the refining mechanism in both single-disc (SD) refiners and conical disc(CD) refiners. LÄS MER

  7. 25. Effects of Food Supplementation and Psychosocial Stimulation on Growth and Development of Severely Malnourished Children : Intervention Studies in Bangladesh

    Författare :Baitun Nahar; Lars-Åke Persson; SM Grantham-McGregor; Tahmeed Ahmed; Kim F Michaelsen; Uppsala universitet; []
    Nyckelord :Psychosocial stimulation; food supplementation; HOME; child-rearing practices; maternal depressive symptoms; severe malnutrition; Bangladesh; International Health; Internationell hälsa;

    Sammanfattning : Early childhood malnutrition is a global public health problem with serious short- and long-term consequences. The aim of this thesis is to evaluate the effects of psychosocial stimulation (PS) with or without food supplementation (FS) on growth and development of severely malnourished children, quality of home environment, mother’s child-rearing practices and depressive symptoms.
