Optimizing Volatile Matter and Ash Content in Environmentally Friendlier Firelighters Based on Wood Residues and Wax Matrices

Global agricultural and forestry processing industries generate vast quantities of bio-based residuals and organic side products annually, prompting a critical need for sustainable material repurposing. This study investigates the thermal performance of environmentally friendly,...

A four-cluster typology of the EU member states in digital public services and institutional governance using DESI and WGI data

Efficient and transparent public services foster a competitive business environment and social well-being by facilitating business expansion, job creation, foreign direct investment, etc. In recent years, digitalisation has become a critical requirement for modern public administ...

Business roles in 1.5 °C transitions: a stakeholder-informed scenario analysis

Limiting global warming to 1.5 °C requires profound transformations of production and consumption systems, yet the role of businesses in enabling such transitions remains insufficiently addressed in scenario-based sustainability research. Existing scenarios often conceptualize fi...

System-Level Validation of Pem Electrolyser Balance of Plant: An Integrated Framework for Functional Performance

Abstract The study presents a system-level validation framework for assessing the functional performance of the balance of plant (BOP) of a proton exchange membrane (PEM) electrolyser. The proposed approach addresses a methodological gap between individual component testing and v...

Specific Responses of Natural Enemies to Ips acuminatus Density in Endemic and Post-Outbreak Populations in Scots Pine Stands: A Case Study

Outbreaks of the sharp-toothed bark beetle, Ips acuminatus, have become increasingly frequent across Europe, yet little is known about how natural enemy communities vary between bark beetle population phases. This study compared the composition, diversity, emergence patterns, and...

New informative molecular markers for Alternaria sections Infectoriae and Pseudoalternaria reveal the diversity of lineages infecting wheat and tomato

Fungi in Alternaria sections Infectoriae and Pseudoalternaria are commonly associated with commercially important crops, yet their biosystematics remains difficult to resolve because standard molecular markers often lack sufficient phylogenetic resolution. In this study, we used...

Independent Engineering Transfer After Traceable Generative-AI-Assisted Learning: A Six-University Controlled Trial with Deterministic Cluster Allocation in Agricultural Engineering Education

Generative artificial intelligence (GenAI) can support engineering problem solving, but whether AI-assisted practice transfers to independent performance after the tool is removed remains unclear. This multicentre controlled trial evaluated a traceable five-stage GenAI-assisted l...

GPR-derived ice thickness of the temperate Hintereisferner glacier (Austrian Alps): evaluation of thickness models

Abstract. Alpine glaciers are retreating rapidly and have a potential for near complete ice loss at the end of the 21st century thus accurate glacier evolution models are crucial for predicting the magnitude and rate of future glacier changes. Without reliable ice thickness asses...

Truthful visualizations for mass spectrometry imaging enable high-spatial-resolution interactive m/z mapping and exploration

Mass spectrometry imaging (MSI) produces high-dimensional molecular data, but practical interpretation remains limited by visualizations that incompletely preserve global structure. We present MSI-VISUAL, an open-source framework for interactive MSI analysis that integrates truth...

Integrated Multi-Row Onion Production Under Contrasting Seasonal Conditions: Seeder Optimization, Nutrient Management, Crop Protection, and EIQ-Adjusted Sustainability

Reliable establishment of direct-seeded onion requires coordinated control of sowing geometry, nutrient supply, crop protection, and resource use. This study combined Hartley-4 optimization of a four-section, multi-row ridge seeder with a two-year randomized complete block experi...

Getting Around the Intrinsic Errors of Density Functional Theory Calculations in Electrocatalysis

Abstract This article shows that the intrinsic gas-phase error in density functional theory (DFT) calculations can be effectively eliminated by referencing adsorption energies and reaction barriers to surface-bound intermediates rather than to molecular species. In oxygen reducti...
