  1. 21. The 200-year history of nss-SO42- concentration in snow and ice from Lomonosovfonna, Svalbard

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maria Schoeps; Josefin Andersson; [2015]
    Keywords : Sulfate; nss-SO42-; ice-cores; glaciochemistry; Lomonosovfonna; Sulfat; nss-SO42-; isborrkärnor; iskemi; Lomonosovfonna;

    Abstract : Environmental scientists use ice-core records to reconstruct past atmospheric conditions. Anthropogenic and natural sources of emissions can be traced when analyzing ions in the ice, which is included in the science of glaciochemistry. Sulfate is an excellent ion to use in these studies since it is traceable to these emissions. READ MORE

  3. 22. Switching to the “Golden Age of Natural Gas” with a focus on shale gas exploitation : a possible bridge to mitigate climate change?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hossein Maazallahi; [2015]
    Keywords : Physical Geography and Ecosystem Science; GEM; shale gas exploitation; fugitive methane; climate change; carbon dioxide; age of natural gas; fossil fuel combustion; Earth and Environmental Sciences;

    Abstract : Currently, policy makers put high attention in supplying global energy demand by focusing on 2°C policy; global temperature anomaly based on the global mean temperature of pre-industrial era (13.7°C). How to keep the 2°C policy at global scope is the main question in climate framework. READ MORE

  4. 23. Atmospheric reactivity of cyclic ethers of relevance to biofuel combustion

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Emelie Graham; [2015]
    Keywords : Ecosystem Science; Physical Geography; 2nd generation biofuels; furans; tropospheric chemistry; ozonolysis; atmospheric kinetics; computational chemistry; IR Spectroscopy; Atmospheric Science Biochemical Cycles; Earth and Environmental Sciences;

    Abstract : Biofuels are considered to be an environmental friendly alternative to fossil fuels as they have the potential to reduce the global emissions of greenhouse gases. Studies have showed that an increased use of ethanol could alter the atmospheric chemical composition and enhance urban ozone concentrations resulting in higher human mortality rates. READ MORE

  5. 24. Evaluation of measurement data for an optical free-space aircraft to ground communication link system

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Vevek Selvaraj; [2014]
    Keywords : Optical Free-space communication; Power Vectors; Shack-Hartmann wavefront Sensors and Finite State Space Markov Model.; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : Optical free-space communication is an e ffective approach that can provide tap-proof, high bandwidth data communications. In this thesis there is an Optical link established between aircraft and the ground station. READ MORE

  6. 25. Non-Governmental Organizations' Efforts to Protect Stratospheric Ozone

    University essay from Lunds universitet/Statsvetenskapliga institutionen

    Author : Hampus Tarras-Wahlberg; [2014]
    Keywords : The Montreal Protocol; non-governmental organizations NGOs ; epistemic communities; ozone layer; Peter Haas; Law and Political Science;

    Abstract : In 1987, the international community adopted the Montreal Protocol on Substances that Deplete the Ozone Layer – subsequently labelled as one of the most successful environmental treaties of our time. In 1992, Peter Haas emerged with a study on epistemic communities and their efforts to protect stratospheric ozone. READ MORE
