1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. LÄS MER
2. Hydrogen fuel in the domestic maritime transport sector of Fiji : A Feasibility Study
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The maritime transport sector accounts for around 2.9% of the world’s anthropogenic emissions, a percentage that is growing yearly. Alternative fuels have come to be considered the necessary solution of the future, not least in island nations such as Fiji that are socially and economically dependent on sustainable maritime transport.

3. 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
4. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER
5. Continuous Hydrothermal Co-liquefaction of Biomass : An experimental study on the effects of fuel mixing on the composition and yield of biocrude and hydrochar
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : An experimental study on the effect of fuel mixing on the products resulting from hydrothermal liquefaction (HTL) was conducted. The feedstocks used were kraft lignin (KL), GROT (GT) and microalgae cultivated in wastewater (MA). Three sets of mixtures were prepared, each containing two types of feedstocks with a 1:1 ratio: KLGT, MAKL, and MAGT. LÄS MER
