  1. 1. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Nadja Rabizadeh; [2023]
    Nyckelord :CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Sammanfattning : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. LÄS MER

  3. 2. Investigating the potential dependence of the apparent diffusivity of lateral self-exchange on mesoporous ZrO2 film

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Paul Wefer; [2023]
    Nyckelord :Lateral self-exchange; mesoporous film; D35; spectroelectrochemistry;

    Sammanfattning : Lateral self-exchange of charge across dye-sensitized film is a phenomenon that may play animportant role in effectivizing H2 production from water via solar energy, and shows potential forother interesting applications. The rate of charge movement via lateral self-exchange across afilm is often quantified in terms of apparent diffusivity of charge, Dapp. LÄS MER

  4. 3. Hydrogeological and economic analysis of a groundwater-based water supply system in rural Nepal

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Författare :Hamon Hedayatnasab; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Access to safe drinking water and sanitation is a given standard and considered as basic human rights in urban areas and industrialized countries. However, 40 % of the world's population living in rural areas in developing countries lack access to safe drinking water. LÄS MER

  5. 4. Modelling and Techno-economic Analysis of a Hybrid CSP/PV System using Solid Oxide Electrolyser for Hydrogen Production

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Chuanyin Tang; [2023]
    Nyckelord :Power to Hydrogen; Solid Oxide Electrolyser; CSP; PV; LCOE; LCOH.;

    Sammanfattning : This project proposes a solar-driven hybrid system for electricity generation and hydrogen production, which includes concentrated solar power (CSP), photovoltaic (PV), solid oxide electrolyser (SOEC). Electricity from the CSP and PV provides a continuous 24/7 supply to meet demand-side power consumption.

  7. 5. CAN LEAF LEVEL GAS EXCHANGE BE USED AS A PREDICTOR FOR DROUGHT TOLERANCE IN COMMON BEAN (PHASEOLUS VULGARIS)?

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Villemo Holmberg; [2022-08-16]
    Nyckelord :;

    Sammanfattning : This study aimed to examine drought tolerance among a variety of landraces of the species Phaseolus vulgaris to discover whether leaf level gas exchange can be used as a predictor for drought tolerance. Beans of different landraces from Rwanda were planted and when they had grown for four weeks a leaf-level gas exchange analysis was carried out, measuring one leaf from each plant both during the day and night.
