1. 1. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Alexina Brännlund; [2023]
   Nyckelord :Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

   Sammanfattning : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

3. 2. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate

   Master-uppsats, KTH/Teknisk mekanik

   Författare :Joseph Vernier; [2023]
   Nyckelord :Computational Fluid Dynamics; Fluid Mechanics; Numerics; Micro-climate modeling; Radiation; Crop modeling; Photovoltaic panels;

   Sammanfattning : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. LÄS MER

4. 3. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.

   Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

   Författare :Regan George; [2023]
   Nyckelord :PHA; HTC-substrate; Polymer;

   Sammanfattning : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.

5. 4. Response of foraminifera Ammonia confertitesta (T6) to ocean acidification, warming, and deoxygenation - An experimental approach

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Elsa Muller; [2023]
   Nyckelord :Acidification; Warming; Deoxygenation; Foraminifera; Ammonia confertitesta T6 ; Culture Experiment; Trace elements; Earth and Environmental Sciences;

   Sammanfattning : Ocean acidification, warmer temperatures, and the expansion of hypoxic zones in coastal areas are direct consequences of the increase in anthropogenic activities. However, so far, the combined effects of these stressors on calcium carbonate-secreting marine microorganisms - foraminifera are complex and poorly understood. LÄS MER

7. 5. Forest Aboveground Biomass Monitoring in Southern Sweden Using Random Forest Modelwith Sentinel-1, Sentinel-2, and LiDAR Data

   Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad

   Författare :Wan Ni Lin; [2023]
   Nyckelord :Aboveground biomass; Sentinel-1; Sentinel-2; LiDAR; random forest; GEE;

   Sammanfattning : Monitoring carbon stock has emerged as a critical environmental problem among several worldwide organizations and collaborations in the context of global warming and climate change. This study seeks to provide a remote sensing solution based on three types of data, to explore the feasibility and reliability of estimating aboveground biomass (AGB) in order to improve the efficiency of monitoring carbon stock.
