  1. 16. Putting the power in plants : using green infrastructure to reduce nonpoint source pollution in aquatic ecosystems in the urban center of Dublin

    University essay from Lunds universitet/LUCSUS

    Author : Tessa Mazar; [2018]
    Keywords : green infrastructure; Dublin; non-point source pollution; urban run-off; sustainability science; Social Sciences;

    Abstract : Coastal ecosystems are some of the most productive, and most at risk, in the world. These ecosystems are at risk due to the high levels of pollution entering the system. Most of this pollution comes from either run off or atmospheric deposition. READ MORE

  3. 17. Estimating area of vector polygons on spherical and ellipsoidal earth models with application in estimating regional carbon flows

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Huiting Huang; [2017]
    Keywords : spherical ellipsoidal earth model; regional carbon flows; map projection; area of a polygon; atmospheric inversions; Earth and Environmental Sciences;

    Abstract : Estimating area of polygons on the Earth’s surface is required in many fields in earth science. In the field of carbon modelling, one application of estimating polygons’ area is to estimate carbon flows for regions. READ MORE

  4. 18. Measurement of the convective heat transfer with wind : Developing and testing an Earth Scaled Atmospheric Temperature Sensor

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Philipp Wittmann; [2016]
    Keywords : Wind; ATS; heat transfer; air temperature sensor; atmospheric temperature sensor;

    Abstract :    The HAbitability, Brine Irradiation and Temperature Package (HABIT) instrument of the ExoMars Surface Platform will investigate the present day habitability of Mars at the near surface environment. This instrument includes three Atmospheric Temperature Sensor's (ATS's) which are similar to the ones previously used on the Rover Environmental Monitoring Station (REMS) of the Mars Science Laboratory (MSL) rover, that has now been operating on Mars for more than four years.

  5. 19. Modelling nitrogen balance in two Southern Swedish spruce plantations

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johannes Loer; [2016]
    Keywords : maximum bearable nitrogen input rate; atmospheric deposition; nitrogen saturation; forest fertilisation; ForSAFE; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Abstract : Emissions from agriculture and the combustion of fossil fuels increase the atmospheric load of reactive nitrogen (N). N deposition is projected to continue posing significant harm both for environmental and human health over the upcoming decades. Eutrophication as a result of N leaching is one of the negative effects of heavy deposition. READ MORE

  6. 20. Tribological evaluation of the contact between upper compression ring and cylinder liner with different surface coatings

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Pär Wassborg; [2016]
    Keywords : piston ring; cylinder liner; wear; friction; grey cast iron; titanium oxide; chromium oxide;

    Abstract : The constant pursuit in the automotive industry to increase the engines performance, new solutions are always developed and tested to reduce the friction and increase the efficiency in the engine. One component that contributes to friction losses is the piston ring pack where the top compression stands for up to 40 %. READ MORE
