    Author : Erik J. Engström; Caroline Leck; Henning Rodhe; Paolo Laj; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soot; black carbon; atmospheric concentration; light absorption; wet deposition; scavenging; wash-out ratio; South-Asia.; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap;

    Abstract : Filter-based optical measurements of light absorbing particulate matter at awavelength of about 550 nm, here referred to as soot, in air and rainwaterhave been performed during the period from 1st June 2005 to 31th May 2009at Godavari in Nepal, Sinhagad in India and Hanimaadhoo in The Maldives.A method for determination of water-insoluble light absorbing matter inrainwater has been developed.

  4. 2. Migration strategies of raptors – spatio-temporal adaptations and constraints in travelling and foraging

    Author : Roine Strandberg; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; route convergence; loop migration; mortality; spatio-temporal distribution patterns; pre- and post-migratory movements; daily travel routines; satellite tracking; fly-and-forage migration; raptors;

    Abstract : My dissertation is about bird migration and addresses questions about how raptors adapt to the fluctuating environments during the transition seasons between breeding and wintering. The migration is highly affected by local prey abundance, foraging strategies, weather conditions and landscape patterns along the migration routes as well as navigation and orientation mechanisms and cues.

  5. 3. Winter maintenance and cycleways

    Author : Anna Bergström; KTH; []
    Keywords : cycleways; winter maintenance; maintenance service level; mode choice; winter cycling frequency; winter road condition assessment; bicycle measurements; friction measurement; winter maintenance equipment;

    Abstract : Increasing cycling as a means of personal travel couldgenerate environmental benefits if associated with acorresponding decrease in car-based transport. In seeking topromote cycling in wintertime, it is desirable to understandhow important the road surface condition is compared to otherfactors in people's decision to cycle or not. READ MORE
