1. 1. Continuous Preventive Bridge Maintenance : Effect of High Pressure Washing on Concrete Bridges

   Författare :Louise Andersson; Johan Silfwerbrand; Anders Selander; Ylva Edwards; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge maintenance; preventive maintenance; chloride ingress; high-pressure washing; Concrete Structures; Betongbyggnad;

   Sammanfattning : In Sweden, as in many other countries, preventive maintenance of structures andbridges is considered important. It provides several benefits such as prolonged lifespan or service life, less need for repair, and hopefully reduced costs and lowerenvironmental impact.A large part of Sweden’s bridge stock is getting quite old.

3. 2. Noise in the preschool : health and preventive measures

   Författare :Fredrik Sjödin; Ulf Landström; Anders Kjellberg; Anders Knutsson; Mats Nilsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Noise; hearing disorders; stress; health; occupational environment; preventive measures; intervention; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Sammanfattning : This thesis is based on noise recordings and health evaluations carried out at preschools in the northern part of Sweden. Sound level recordings were made on individuals and by use of stationary devices in dining rooms and play halls. Health evaluations were based on ratings by use of questionnaires and by analyses of cortisol. LÄS MER

   Sammanfattning : With a demographic change towards an older population, the structure of the labor force is shifting, and people are expected to work longer within their extended life span. However, for many people, wellbeing has been compromised by work-related problems before they reach the retirement age. LÄS MER

5. 4. Tracking Theory for Preventive Safety Systems

   Författare :Lars Danielsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle tracking; sensor data fusion; automotive; active safety systems; sensor models; warning integration; motion models; fusion strategies; human machine interface; preventive safety systems;

   Sammanfattning : Preventive safety systems rely on accurate information from a sensing system regarding the current traffic situation to make decision whether to inform, warn or intervene to avoid an impeding collision or to mitigate its consequences. This thesis mainly considers tracking algorithms to enhance these systems through making the best use of the information supplied by on-vehicle sensors, such as radar and vision sensors. LÄS MER

7. 5. An ounce of prevention is worth a pound of cure : preventive home visits among healthy seniors

   Författare :Klas-Göran Sahlén; Lars Lindholm; Lars Dahlgren; Carsten Hendriksen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preventive home visits; mortality; care utilisation; senior production; cost effectiveness; realist synthesis; Public health science; Folkhälsovetenskap; hälso- och sjukvårdsforskning; health services research;

   Sammanfattning : The aim of this thesis is to contribute to existing knowledge. If the knowledge is not useful in building society it has limited value. In order to be a tool for decision-makers, Preventive Home Visits (PHVs) are described and discussed according to a realist synthesis approach. LÄS MER
