  2. 1. Brief online interventions for concerned gamblers in a gambling helpline

    Author : Håkan Wall; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Problem gambling (PG) is common throughout the world and affects approximately 2% of the adult population in Sweden and most other western countries. Individuals who gamble in a problematic way experience negative consequences in various life domains, such as, economy, physical and mental health, work life and/or in the relations with family and friends.

  4. 2. Simulation-Driven Design of Complex Mechanical and Mechatronic Systems

    Author : Johan Wall; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exhaust system; Experimentation; Machine tools; Mechatronics; Optimisation; Product development; Prototyping; Simulation; Structural dynamics;

    Abstract : Effective and efficient product development is critical to business success on the increasingly competitive global market, and simulation has proven to support this in many sectors. The aim of this thesis is to study how properties of complex mechanical and mechatronic systems can be more efficiently and systematically predicted, described, assessed and improved in product development.

  5. 3. Feasibility and efficacy of incorporating an exoskeleton in gait training during subacute stroke rehabilitation

    Author : Anneli Wall; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Introduction: Hemiparesis is the most common acute manifestation of stroke and often has a strong negative impact on walking ability leaving one third of patients dependent in walking activities outside one’s home. Improved methods for training of gait during stroke rehabilitation could tackle the challenge of achieving independent walking and promote better outcomes. READ MORE

  6. 4. Numerical Studies of Wall Effects of Laminar Flames

    Author : Johan Andrae; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wall effects; laminar premixed flames; Chemkin; boundary layer flow; Chemical engineering; Kemiteknik;

    Abstract : Numerical simulations have been done with the CHEMKINsoftware to study different aspects of wall effects in thecombustion of lean, laminar and premixed flames in anaxisymmetric boundary-layer flow. The importance of the chemical wall effects compared to thethermal wall effects caused by the development of the thermaland velocity boundary layer has been investigated in thereaction zone by using different wall boundary conditions, walltemperatures and fuel/air ratios.

  7. 5. Protected Attractions : Tourism and Wilderness in the Swedish Mountain Region

    Author : Sandra Wall Reinius; Gunnel Forsberg; Annika Dahlberg; Peter Fredman; Jarkko Saarinen; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Landscape value and perception; nature conservation policy; tourist behavior; tourist attraction; infrastructure; visitor survey; nature-culture dichotomy; Laponian World Heritage Area; Sweden; Human geography; Kulturgeografi; kulturgeografi; Human Geography;

    Abstract : Europe's first national parks were established in northern Sweden in 1909 and this region has thus functioned as a protected and aesthetic pleasure landscape for a century. In 1996, due to the combination of spectacular natural environment and ancient Sami traditions the Laponian World Heritage Area was established here. READ MORE
