  1. 1. Fiberoptik leder dagsljus och möjliggör grönska : gestaltningsförslag för en mörk gång- och cykeltunnel i Järfälla kommun

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Rut Lindeberg; [2019]
    Keywords : direktinfallande dagsljus; fiberoptik; mörk urbanmiljö; skuggväxt;

    Abstract : Mörka underbyggda platser är vanligt förekommande i våra städer. De är nödvändiga för att vi enkelt ska kunna ta oss mellan stadens olika delar, men de tillför sällan något annat än funktion. Syftet med den här uppsatsen är att undersöka hur fiberoptik kan leda dagsljus och möjliggöra grönska i en mörk gång- och cykeltunnel. READ MORE

  2. 2. Thermodynamic and Economic Evaluation of Hybridization Biomass-solar for a Cogeneration Power Plant in a Cuban Sugar Mill, George Washington

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Silja Lehtinen; [2019]
    Keywords : ;

    Abstract : This study evaluates the thermodynamic and economic performance of hybridization of biomass-solar for a cogeneration power plant in a Cuban sugar mill, George Washington. The evaluation is performed by varying the parameters of the thermal power block and considering scenarios with 1) bagasse and marabú, 2) bagasse and solar field, and 3) bagasse, marabú and solar field as heat sources for the cogeneration cycle.

  3. 3. A Preliminary Optimisation and Techno-economic Analysis of Solar Assisted Building Heating System Using Transpired Air Solar Collector and Heat Pump in Sweden

    University essay from Högskolan Dalarna/Energiteknik

    Author : Puneet Kumar Saini; [2019]
    Keywords : Solar energy; air heating; Optimisation; heat pump; transpired air collector;

    Abstract : This thesis presents an optimisation approach and techno-economic evaluation tool for a system consisting of a transpired solar air collector and air source heat pump in a series arrangement. The thesis also investigates the application of the developed tool for feasibility study of a solar heat pump system for a group of three multi-family houses located in Ludvika, Sweden. READ MORE

  4. 4. Sodium trapping in aluminium current collectors

    University essay from Uppsala universitet/Strukturkemi

    Author : Ville Nyström; [2019]
    Keywords : Na; sodium; trapping; current collector; Al; aluminium; glyme; diglyme;

    Abstract : The aim of this master thesis was to establish if sodium is trapped in aluminium current collectors, which in turn could affect the capacity fade in sodium-ion battery systems. In the case of lithium-ion batteries, previous studies have shown that a trapping mechanism, where lithium diffuses through the active material and current collectors, can explain the capacity fade observed for several systems.

  5. 5. Women and Water in the Lake Chad Area: Participation and Influence in Water Management Processes

    University essay from Lunds universitet/Statsvetenskapliga institutionen

    Author : Linn Boberg; [2019]
    Keywords : Women; Lake Chad River Basin; Women Participation; Women Influence; Shared Water Resources; Water Resource Management; Law and Political Science;

    Abstract : The riparian countries of Lake Chad River Basin – Nigeria, Niger, Cameroon and Chad – suffer from environmental degradation as the lakes surface water has decreased with 90 percent since the 1960’s. This has put pressure on the population around the lake as the livelihood for many of them is dependent of the lake’s water. READ MORE
