Al-Ga-based alloys are promising carriers of renewable energy, which can provide hydrogen by hydrolysis in challenging working environments. Manipulating their performance by different process conditions and comprehending the mechanisms are important for achieving directional design synthesis of alloys and enhancing their practicality. This study presents a novel approach to optimizing the hydroge
Recognizing the challenges in using botanicals as sustainable pest control agents due to compositional variation, this study addresses the limitations of traditional component-based approaches such as Hewlett and Plackett or Wadley’s models. Based on the assumption of noninteractivity among constituents, these models often fail to predict outcomes accurately due to dynamic intermolecular interacti
Populärvetenskaplig sammanfattning: Sen den industriella revolutionen har koldioxidhalten i atmosfären nästan fördubblats, från 280 ppm till 360 ppm. Detta har skapat stora diskussioner om hur vårt klimat kommer att påverkas. Koldioxid (CO2) är en växthusgas och med detta menas att den absorberar inkommande energi och på så sätt värmer upp vår jord. I denna studie har fokusen lagts på hur vegetatiIncreasing levels of CO2 in the atmosphere may substantially increase net primary productivity (NPP) and thereby increase carbon sequestration by terrestrial ecosystems. Realistic Free Air Carbon Enrichment (FACE) experiments tend to show a NPP enhancement of about 25% if CO2 is elevated by 200 ppm. In this study two generalized vegetation models, the Lund-Postsdam-Jena dynamic generalized vegetat
In this essay I discuss different normative foundations - theories of political ethics, for proposed cures to market failures. In addition to empirically match what cure fit what type of market failure, I posit the notion that the normative position of an economist, or policy maker, or of a group, concerned with these problems, delimits the options available for recommending, or analysing, what co
Pollinators such as Bombus terrestris play a vital role in ecosystem stability and agricultural productivity. Developing methods to estimate key biological traits such as age and weight is crucial for advancing ecological understanding and conservation efforts. In eusocial insects like B. terrestris, age and weight influence behaviour, task allocation, and survivability, but traditional methods fo
With the rapid advancement of electromobility sector, the power density and heat generation of electronic chips is significantly rising. Due to its higher load and lower thermal mass, electronics chips in BEV inverters, such as MOSFETs, are increasingly susceptible to rapid temperature rises. Through the utilization of latent heat absorption, Phase Change Material (PCM) offers a promising passive
The thesis investigates European economic policy uncertainty and its influence on the currency risk premium embedded in the EUR/USD exchange rate. We build a time-series regression model utilizing monthly data from 1999 to 2020. Currency risk premium is proxied with realized excess returns. The model uses control variables for inflation differentials, and global risk sentiment, proxied by the VIX
RQ: What is the relationship between organizational structure and its sustainability efforts, and how do perceptions of sustainability efforts vary across different job functions within a company? Purpose: The purpose of this paper is to better understand the current state of sustainability efforts in large organizations. Especially to recognize how the structure of the company might pose issues
Uppsatsen syftar till att undersöka hur miljöförsvarare kan skyddas inom EUrätten i utövandet av civil olydnad. Syftet baseras till stor del på- och inspireras av Guidelines on Peaceful Environmental Protest and Civil Disobedience som Specialrapportören för miljöförsvarare under Århuskonventionens nyligen har publicerat. Vidare bygger uppsatsen på ett antal internationella konventioner för att undThis graduate thesis aims to examine possible avenues for protection for environmental defenders exercising civil disobedience within the EU legal framework. The aim is based on and inspired by the Guidelines on Peaceful Environmental Protest and Civil Disobedience published in 2025 by the Special Rapporteur on Environmental Defenders under the Aarhus Convention. Further, the graduate thesis buil
The increasing demand for electric vehicle charging stations creates new challenges for electric grid planning. This thesis proposes a framework for forecasting realistic 24-hour peak load profiles for new direct current fast-charging stations without historical observations. The method combines $K$-means clustering of existing stations’ hourly load patterns and random forest models that predict b
The global decline of seagrass meadows has increased the need for effective restoration strategies, yet recovery is often limited by physical environmental stressors. This thesis investigates the hydrodynamic thresholds influencing seagrass seedling survival and recruitment along the Adelaide coastline in Gulf St. Vincent, South Australia. The study focuses on two sites with similar environmental
This thesis investigates simulating X-ray computed tomography with two primary objectives: developing a virtual representation of an X-ray computed tomography scanner and generating labelled synthetic training data for deep learning-based fibre segmentation. A simulation pipeline to generate X-ray projections based on the Beer-Lambert law was developed using the open-source framework gVirtualXray.
INTRODUCTION: Women are increasingly entering the dementia research workforce, but they frequently fail to attain senior leadership positions in academia. Discrepancies in academic research outputs were investigated to guide equity-focused policy recommendations.METHODS: Bibliometrics was conducted on 400,482 original research articles (2003-2022) followed by surveying the AD/ADRD research communi
Objectives To assess the performance of the ALL IN TRIPLEX rapid antigen-based test for SARS-CoV-2, influenza A, influenza B, and respiratory syncytial virus. We focus on the potential of the test to be used in acute clinical settings as a marker of infectiousness, by determining the sensitivity at different real-time PCR cycle threshold (Ct) levels, as well as the quantity of absorbed viral RNA n
Background/Objectives: Radiostereometric analysis (RSA) is the gold standard for measuring implant migration, with CT-RSA increasingly used as an alternative. To evaluate CT-RSA, it is important to assess data that include the surrounding soft tissues, rather than data from simplified phantoms, while also avoiding unnecessary radiation from multiple scans. This study proposes a method for generati
This study presents a coupled model incorporating a thermal propagation model and a fire model to investigate the fire safety of a large lithium-ion battery (Li-ion) module. The thermal propagation model employs a three-dimensional (3D) finite element method (FEM), while the fire model utilizes computational fluid dynamics (CFD). Literature data on material properties and thermal runaway character
To solve the problem of fatigue of the UAV operator during long-term search and reconnaissance missions, a research hardware and software complex was created, in which the positioning of the auxiliary UAV video camera with a narrow field of view is carried out. Dynamixel Library for MATLAB and Simulink was used to organize the interaction of actuators with the virtual environment, which allows com
2-amino-2-methyl-1-propanol (AMP) in dimethyl sulfoxide (DMSO) is a precipitating non-aqueous amine technology that can potentially lower the energy demand during CO2 removal from industrial flue gases compared to aqueous amine technologies. However, DMSO is hygroscopic and has a high possibility of absorbing water from humid flue gases, which can affect the physical properties of the system,
PURPOSE OF REVIEW: Small cell lung cancer (SCLC) is an aggressive disease with a poor prognosis, whereas its metastatic capacity carries a predilection for the brain. Although prophylactic cranial irradiation (PCI) has been used to address this problem, upcoming alternatives might necessitate reflection of its application in SCLC treatment. RECENT FINDINGS: The addition of immunotherapy to treatme
