11. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D
Master-uppsats, Lunds universitet/MaterialteknikSammanfattning : 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
12. Investigation of Potentially Toxic Elements in Agriculture Soil : Greenhouse and Open-field Farming in Türkiye
Master-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : 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
13. Ackumulering av Tungmetaller i Salix Spp : Ett Hållbart Sätt att Sanera Förorenat Sediment
Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)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
14. Upptagshastigheter av metaller med salix
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : 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.

15. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking
Master-uppsats,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
