Phosphorus (P) is a critical macronutrient for plant growth, often limiting plant production in areas where plant demand is higher than soil supply. In contrast to nitrogen (N), P cannot be sourced from the atmosphere; therefore, where it is rare, it becomes a strong constraint on primary production. Due to this, most dynamic global vegetation models (DGVMs) are incorporating a prognostic P cycle
Land cover and land management changes (LCLMCs) have a substantial impact on the global carbon budget and, consequently, on global climate via the biogeochemical (BGC) effects. The commonly considered BGC effects refer to the direct influence of LCLMCs on local carbon stocks (local BGC effects). However, LCLMCs also influence climate by altering the local surface energy balance due to changes in l
The Paris Agreement of the United Nations Framework Convention on Climate Change is a binding international treaty signed by 196 nations to limit their greenhouse gas emissions through ever-reducing Nationally Determined Contributions and a system of 5-yearly Global Stocktakes in an Enhanced Transparency Framework. To support this process, the European Commission initiated the design and developme
Advances in Earth observation capabilities mean that there is now a multitude of spatially resolved data sets available that can support the quantification of water and carbon pools and fluxes at the land surface. However, such quantification ideally requires efficient synergistic exploitation of those data, which in turn requires carbon and water land-surface models with the capability to simulta
If you really want to know how much Australia contributes to the amount of carbon dioxide (CO₂) in the atmosphere, you have to study all the “sources” and “sinks”.Sources release CO₂ into the atmosphere, while sinks take it out. There are sources from human activities, such as burning fossil fuels, and there are natural sinks such as plants absorbing CO₂. You can tally it all up on a balance sheet
Introduktion: Dataspelande är en väldigt vanlig fritidssyssla och en majoritet av svenska ungdomar uppger att de spelar dataspel dagligen. En minoritet av dessa utvecklar ett problematiskt spelbeteende, ett fenomen som fått formellt erkännande i och med att diagnosen Gaming Disorder (GD) inkluderats i diagnossystemet ICD-11. Nu efterfrågar både barn- och ungdomspsykiatrin (BUP), skolhälsovården oc
Smallholder farmer-based rural social movements have been heralded as a promising source of political power with the potential to effectively promote sustainable trajectories of agricultural development in Sub-Saharan Africa and beyond. However, the very early stages of rural social movement building remain understudied, including under what conditions such nascent efforts are likely to lead to ef
Australia, characterized by extensive and heterogeneous terrestrial ecosystems, plays a critical role in the global carbon cycle and in efforts to mitigate climate change. Prior research has quantified vegetation productivity and carbon balance within the Australian context over preceding decades. Nonetheless, the responses of vegetation and carbon dynamics to the evolving phenomena of climate cha
This thesis is based on the results concerning the epitaxial growth and characterization of silicon (Si) and germanium (Ge) nanostructures. The growth technique was the Ultra High Vacuum Chemical Vapor Deposition (UHV-CVD) that works in relatively low temperatures and low growth pressures. The UHV-CVD chamber was also used for the reduction experiments. The work presented here involves three diff
The study was conducted by thematic analysis from secondary data such as literatures, reports and website, and ten interviews which respondents’ backgrounds are experts from ready meal and its packaging related areas. The whole paper followed the structure build from the analysis: Servings and portions, Distributions, Ready meal market and its evolution, Consumer perspective, Ready meal packaging
Increasing the effectiveness and efficiency of production processes have always been a significant challenge, primarily because such processes often contain activities that lead to waste. In response to address these challenges, tools like Lean and Six Sigma, and over time their descendant, Lean Six Sigma (LSS) were developed. It is argued that Industry 4.0 proliferated data accessibility in the m
This thesis explores the transformative impact of social media platforms on communication and representation. More specifically, it investigates the themes of motherhood portrayed in the YouTube videos of Swedish party leaders and how these themes relate to the process of democratic representation. The research centers around former Center party leader Annie Lööf and the current Christian Democrat
The present study is a qualitative exploration of the motivations to study abroad within a group of Chinese students. The insights presented here are founded on an ethnographic fieldwork at Fudan University in Shanghai, China. The fieldwork entailed participant observation and qualitative interviews with students who where either currently enrolled at Fudan University or recent graduates. The puzz
Part of the Northern Hemisphere has experienced widespread autumn cooling during the most recent decades despite overall warming, but how this contrasting temperature change has influenced the ecosystem carbon exchange remains unclear. Here, we show that autumn cooling has occurred over about half of the area north of 25° N since 2004, producing a weak cooling trend over the period 2004–2018. Mult
