  1. 1. Insight into the water oxidation mechanism on nickel hydroxide electrocatalysts : Density Functional Theory calculations and Electrochemical experiments

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonatan Mossegård; [2016]
    Keywords : ;

    Abstract : Hydrogen production is an interesting way to store solar energy and to diversify the range of applications for indirect solar power. A promising production method is to use electric power from solar photovoltaic cells to split water in an electrolysis setup. READ MORE

  2. 2. The water footprint of coffee production in Miraflor, Nicaragua

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Emma Moberg; [2016]
    Keywords : Water footprint; water footprint assessment; consumptive water use; water pollution; Nicaragua; coffee; Vattenfotavtryck; konsekvensanalys; vattenanvändning; vattenkonsumtion; vattenförorening; Nicaragua; kaffe;

    Abstract : A water footprint is a tool for assessing the impacts of freshwater use by mapping the water useof the production of a good or a service, a process in a production chain, a business or even of a whole country. One of the most commonly used methods for calculating the water footprint was developed by the Water Footprint Network (WFN). READ MORE

  3. 3. Säkrare etablering av våroljeväxter med grund bearbetning på våren

    Author : Hilding Tornerhjelm; [2016]
    Keywords : jordbearbetning; vårraps; såbädd; såtidpunkt; jordloppor; uppkomst;

    Abstract : Spring oilseed rape is an important break crop in cereal dominated crop rotations in Mälardalen. Also, it is one of few good preceding crops to winter wheat. Establishment of spring oilseed rape is perhaps the most critical moment in arable cropping, especially under dry conditions on clay soils. READ MORE

  4. 4. Short-Term Surface Velocity Changes During Summer in the Lower Part of the Ablation Area Using Differential GPS Survey, Storglaciären, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : David Grenot; [2016]
    Keywords : DGPS; short-term ice velocity; infinitesimal strain; Storglaciären; ablation area; DGPS; korttidsvariationer i isflöde; deformation; Storglaciären; ablationsområde;

    Abstract : short time scale. Four differential GPS stations were installed in the lower ablation area of Storglaciären in Sweden for one week in August 2012. The position data over the period were then compared with the environment information including temperature, precipitation, known hydrology and topography. READ MORE

  5. 5. The Impacts of Urban Heat Islands on Northwestern European Cities: Characterising the heat island intensity based on land use data

    University essay from Luleå/Department of Civil, Environmental and Natural Resources Engineering

    Author : Twan Rovers; [2016]
    Keywords : climate-sensitive urban design; urban heat island UHI ; heat mitigation; local climate zone LCZ ; Northwestern Europe;

    Abstract : Many urban and suburban areas experience higher temperatures than their outlying rural surroundings. This difference in temperature is what constitutes an Urban Heat Island (UHI). UHIs result from man-made modifications of the natural environment. READ MORE
