  1. 1. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Malin Ahlbäck; [2020]
    Keywords : Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Abstract : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. READ MORE

  2. 2. Design and Optimization of Ultrafiltration Membrane Setup for Wastewater Treatment and Reuse

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ekansh Sharma; [2020]
    Keywords : parameters; membrane; predict; optimize; quality; reduction;

    Abstract : With the advances in the membrane technology, there is an ongoing quest to determine the best optimal configuration for an adopted treatment as well as it’s polishing to achieve cumulative sustainability for the treatment process. Henceforth, this thesis report is an evaluation to devise a membrane filtration process for investigating the possibility of treating pre-sedimented municipal wastewater with ceramic ultrafiltration, optimizing the membrane as a pre-treatment for reverse osmosis as an overall strategy for recovering wastewater.

  3. 3. Rainwater Infiltration Model of the Chocaya Basin using Hydrus-1D

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Alexander Bergman; Mire Persmark; [2020]
    Keywords : Rainwater Infiltration; Alluvial Plain; Chocaya Basin; Hydraulic Conductivity; Double Ring Infiltrometer DRI ; Hydrus-1D; Electrical Resistivity Tomography ERT ; Earth and Environmental Sciences;

    Abstract : The objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. READ MORE

  4. 4. FLUX : Rethinking two-wheel mobility

    University essay from Umeå universitet/Designhögskolan vid Umeå universitet

    Author : Philip Beller; [2020]
    Keywords : motorcycle design; safety; practicality; sustainable mobility;

    Abstract : This project has investigated how to reshape two-wheel mobility in a more functional driven way, without losing the thrill of riding a motorcycle. The intitial cue was offered by the current rise of electric powertrains in the market. READ MORE

  5. 5. INTERMEDIATE-SCALE TESTS AND CONE CALORIMETER TESTS - FIRE BEHAVIOUR OF SELECTED FACADE MATERIALS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Tanja Cernosa; [2020]
    Keywords : Fire behaviour; Intermediate-scale facade tests; cone calorimeter; stone wool; phenolic foam; WRB; Technology and Engineering;

    Abstract : In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times.
