  2. 21. Strengthening and degradation mechanisms in austenitic stainless steels at elevated temperature

    Author : Muhammad Farooq; Rolf Sandström; Göran Engberg; KTH; []
    Keywords : ;

    Abstract : With rapid economic developments and rising living standards, the demand for electricity all over the world is greatly increased. Due to high fuel costs, the steam boilers with higher steam temperature and pressure are needed to decrease the cost of power generation throughout the world extensively. READ MORE

  4. 22. Intrafollicular pressure and biochemical mediators in ovulation

    Author : Markus Matousek; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovulation; protein tyrosine kinase; ovulation; leukotriene B4; intrafollicular pressure; contractions and smooth muscle cell.;

    Abstract : Ovulation is the process whereby the preovulatory follicle ruptures to enable a fertilisable ovum to escape from the interior of the ovary to the oviduct. During the ovulatory process, from he onset of the preovulatory LH-surge to the follicular rupture, marked biochemical and structural changes in follicles to enable it to rupture. READ MORE

  5. 23. Altered movement patterns and deviating muscular activity in individuals with anterior cruciate ligament injury

    Author : Anna Trulsson; Människan i rörelse: hälsa och rehabilitering; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Movement pattern; Physiotherapy; Motor control; Sensorimotor control; Neuromuscular control; Anterior cruciate ligament; Muscular activity; Motor skills; Single leg squat; Electromyography EMG ; Postural orientation; Assessment; Task performance; Reproducibility of findings; Performance test; Hop test; knee; dynamic joint stability;

    Abstract : The purpose of this thesis was to increase the understanding of altered movement patterns in individuals with anterior cruciate ligament (ACL) injury in order to improve ACL rehabilitation, and to develop an observational instrument termed Test for Substitution Patterns (TSP) for standardized, quantifiable scoring of altered movement patterns in legs and trunk. In all, 142 participants, 93 with ACL-rupture (37 women) and 49 uninjured participants were investigated. READ MORE

  6. 24. Impact Simulation of Adhesively Joined Structures

    Author : Thomas Carlberger; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive joining; Dynamic fracture; Cohesive zone; Interphase Element; Bi-material joining; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Abstract : The development of competitive and crashworthy automotive car bodies has reached so far that the manufacturers no longer rely on mono-material steel structures. Improved strength/weight performance may be achieved by using optimal material in each part of the car structure, leading to bi-material joints and ruling out spot welding; the common joining method during the past half century of automotive history.

  7. 25. In Search of Scientific Methods for Conservation of Historic Silk Costumes

    Author : Johanna Nilsson; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; silk; artificial ageing; Queen Christina; historic costumes; conservation; ATR-FTIR; SEC; DRIFTS; tensile tests;

    Abstract : The general aim of this dissertation is to lay ground for the evaluation of conservation methods for historic costumes. The Royal Armoury, Stockholm has a large number of 17th century men’s garments, many of them made of silk and in need of conservation. READ MORE
