  1. 11. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Johan Ranstad; [2023]
    Nyckelord :Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Sammanfattning : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. LÄS MER

  3. 12. Investigation of Potentially Toxic Elements in Agriculture Soil : Greenhouse and Open-field Farming in Türkiye

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Furkan Özkan; [2023]
    Nyckelord :Agriculture; Fertilizer; Organic Farming; Potentially Toxic Elements PTE ; Tarım; Gübre; Organik Tarım; Potansiyel Toksik Elementler PTE;

    Sammanfattning : Greenhouse food production has intensive fertilizer practices, and it leads to contamination in the soil and food chains. This study investigated the potentially toxic elements (As, Pb, Zn, Cd, Cr, Cu, and Ni) (PTE) in agriculture soil and their bioaccumulation by dragon fruit and banana. LÄS MER

  4. 13. Ackumulering av Tungmetaller i Salix Spp : Ett Hållbart Sätt att Sanera Förorenat Sediment

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Taha Basem; [2023]
    Nyckelord :Bioenergi växter; tunga metaller; fytoremediering; färsk-torrvikt; transferfaktor; netto ackumuleringsfaktor.;

    Sammanfattning : Förorenat sediment är ett miljöproblem i Sverige. Detta sediment kan innehålla giftiga tungmetaller såsom Cu, Pb och Zn som kan skada människor och djur. Antropogena aktiviteter som industriutsläpp, jordbruk och felaktig hantering av avloppssystem är en betydande anledning till att detta förorenat sediment finns. LÄS MER

  5. 14. Upptagshastigheter av metaller med salix

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Anton Lilja; [2023]
    Nyckelord :phytoremediation; phytoextraction; salix; metals; landfill leachate; leachate management; fytosanering; fytoextraktion; salix; metaller; deponilakvatten; lakvattenhantering;

    Sammanfattning : Phytoremediation is a technology that can be used in several ways to remediate polluted soils and water. Today, phytoremediation is viewed by many as a technology in the development phase and therefore it is important to evaluate existing facilities to create more support for future establishment.

  7. 15. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking

    Master-uppsats,

    Författare :Delshad Mansour Ayoubi; [2022-12-06]
    Nyckelord :Medical physics; Activity concentration; Transfer coefficient; Dose;

    Sammanfattning : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. LÄS MER
