  1. 1. Controlling the Roll Responses of Volume Carriers

    Author : Carl-Johan Söder; Anders Rosén; Jan De Kat; KTH; []
    Keywords : PCTC; parametric roll; roll response; roll damping; rudder control; aerodynamic roll damping; roll mitigation; racking; Ikeda’s method; CFD; model tests; Full-scale tests; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Modern volume carriers such as container vessels, cruise ships and Pure Car and Truck Carriers (PCTC’s) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this doctoral thesis aims at enhancing the predictability and control of these critical roll responses. READ MORE

  2. 2. Controlling the Roll Responses of PCTC's

    Author : Carl-Johan Söder; Jakob Kuttenkeuler; Dominic Hudson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PCTC; parametric roll; roll response; roll damping; rudder control; roll mitigation; racking;

    Abstract : Modern Panamax Pure Car and Truck Carriers (PCTC) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this licentiate thesis aims at enhancing the predictability and control of these critical roll responses. READ MORE

  3. 3. Families of young children with autism spectrum disorder in Sweden: The role of culture and intergenerational support

    Author : Rano Zakirova Engstrand; Lise Roll-Pettersson; Mara Westling Allodi; Tatja Hirvikoski; Richard Hastings; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; young children with autism; system-theory perspective; culturally diverse families; parents’ explanatory models of autism; grandparents’ needs; cultural formulation; Swedish support system; specialpedagogik; Special Education;

    Abstract : Children with autism spectrum disorder (ASD) have shown high variability in learning outcomes in response to evidence-based interventions, suggesting a need for individualization of intervention programmes for each child and his/her family. To explain this variability and develop effective intervention strategies research suggested focusing on identification of important contextual factors that might influence the effectiveness of a specific intervention for each child such as family cultural characteristics and characteristics of service settings and systems.

  4. 4. Analysis of Response and Development of Permanent Deformation of Unbound Granular Materials Using a Testing Box Technique

    Author : Ebrahim Parhamifar; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unbound granular materials; testing box; response; permanent deformation;

    Abstract : The main objective of this thesis is to study the response and development of permanent deformation in unbound granular materials, theoretically and experimentally. A testing box technique is used here to more closely simulate the behaviour of unbound aggregates subjected to external vertical loading. READ MORE

  5. 5. Acute pancreatitis - Cellular response and dynamic inflammatory changes

    Author : Marwan Dib; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Veterinary medicine:surgery; inflammatory mediators.; adhesion molecules; endothelial barrier dysfunction; inflammatory response; mast cell; abdominal sepsis; Acute pancreatitis; physiology; pathology; clinical studies; Veterinärmedicin:kirurgi; fysiologi; patologi; kliniska studier;

    Abstract : Acute pancreatitis (AP) is a common disorder where underlying mechanisms for the local initiating events in the pancreas, the systemic dissemination of the inflammatory response and the remote organ dysfunction still are unclear. The aim of the present study was to further characterize the dynamics and sequence of the immune response in AP, and to determine the cellular origin of the initiating events. READ MORE
