  1. 16. Epidemiology of unintentional injuries in rural Vietnam

    Författare :Hoang Minh Hang; Peter Byass; Ton That Bach; Ruth Bonita; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; unintentional injury; community-based; surveillance; Vietnam; Folkhälsomedicin; Public health medicine research areas; Folkhälsomedicinska forskningsområden; epidemiologi; Epidemiology;

    Sammanfattning : The main objective of this epidemiological study was to assess the incidence of unintentional non-fatal injuries, together with their determinants and consequences, in a defined Vietnamese population, thus providing a basis for future prevention. A one-year follow-up survey involved four quarterly cross-sectional household injury interviews during 2000. LÄS MER

  3. 17. A methodology for operations-based safety appraisal of two-lane rural highways : Application in Uganda

    Författare :Godfrey Mwesige; Harilaos Koutsopoulos; Basil Psarianos; KTH; []
    Nyckelord :passing zones; passing rate; collision risk; accepted gap; time-to-collision; passing sight distance; two-lane rural highways; Uganda; Transportvetenskap; Transport Science;

    Sammanfattning : The majority of the road infrastructure in developing countries consists oftwo-lane highways with one lane in each travel direction. Operational efficiency of these highways is derived fromintermittent passing zones where fast vehicles are permitted by design to pass slow vehicles using the opposite traffic lane. LÄS MER

  4. 18. Road construction materials as a source of pollutants

    Författare :Åsa Lindgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

    Sammanfattning : This thesis deals mainly with road construction materials, particularly in cases where they may contribute polluting substances. The complexity of the measuring and evaluation of some pollutants with respect to sampling and chemical analysis is considered. LÄS MER

  5. 19. Seed mobility and connectivity in changing rural landscapes

    Författare :Alistair G. Auffret; Sara Cousins; Robin Pakeman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Conservation; Functional connectivity; Historical ecology; Human-mediated dispersal; Invasive species; Landscape Ecology; Long-distance dispersal; Restoration; Seed bank; Seed dispersal; Seed rain; Structural connectivity; Physical Geography; naturgeografi;

    Sammanfattning : The success or failure of many organisms to respond to the challenges of habitat destruction and a warming climate lies in the ability of plant species to disperse between isolated habitats or to migrate to new ranges. European semi-natural grasslands represent one of the world's most species-rich habitats at small scales, but agricultural intensification during the 20th century has meant that many plant species are left only on small fragments of former habitat.

  7. 20. Factors Associated with Motorcylists' Safety at Access Points along Primary Roads in Malaysia

    Författare :Marizwan Manan; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; access point; primary road; motorcyclists’ behavior; Safety Performance function; Motorcycle accident fatality;

    Sammanfattning : More than 50% of road accident fatality victims in Malaysia are motorcyclists, numbering more than 4,000 fatalities per year. The aim of this thesis is to investigate motorcyclists’ road safety problems in general in Malaysia, and narrow down the focus to the most salient road infrastructure related risk factors. LÄS MER
