Toward Autonomous Ecological Monitoring with Betaflight FPV Drones: Test-Stand Validation of a Lightweight Visual Servoing Pipeline

Small first-person-view (FPV) drones provide a flexible platform for ecological and environmental monitoring tasks, including the localization of pollution sources, inspection of contaminated areas, and low-disturbance observation of wildlife. However, Betaflight, one of the most...

Study of the Method of Mixing Oxidizing Agent and Fuel in the Combustion Process

This study investigates the combustion of natural gas in a simple 2 kW co-flow laboratory burner with the primary objective of identifying the most effective combination of interchangeable mixing-chamber nozzle and oxidizer swirler for achieving stable combustion, comparatively l...

C60-Modified Diazonium Cation as a Reactive Agent in Electrochemical Synthesis of Thin Fullerene-Containing Polymeric Films on the Glassy Carbon Electrode

Abstract The electrochemical reduction of the 4-(4,5-fullero-1-methylpyrrolidin-2-yl)benzenediazonium (C60-pyr-benN2+) cation on glassy carbon electrode (GCE) results in the formation of a fullerene-based polymeric phase (poly-C60-pyr-ben) at the electrode surface. The electrode...

Functionalization of Metal-Enriched Pleurotus Biomass with γ-Poly-Glutamic Acid for Cytoprotective and Antimicrobial Wound Care

Objectives: Chronic wound dressings require active components that support moisture management, biocompatibility, and local bioburden control. Therefore, in this study, freeze-dried biomass of Pleurotus ostreatus (Po) and Pleurotus djamor (Pdj) was cultivated in vitro under miner...

A Dual Sharing Strategy in Multi-Task Learning for Harmonic Signal Decomposition

Our work presents the use of neural networks for power grid voltage quality analysis. Power quality parameters are defined by regulations, and therefore knowledge of voltage harmonics is essential for assessing electrical energy quality and connected loads. We propose a new dual...

Hematite-modified calcined bamboo biochar composite enhances soil biochemical functioning and reduces antimony phytoavailability in agricultural soil

Antimony (Sb) contamination severely threatens soil quality, ecological functioning, and crop productivity in agricultural systems. This study investigated the potential of a calcined bamboo biochar–hematite composite (BHC) to reduce Sb phytoavailability and improve soil biochemi...

Data-calibrated cost-aware freight routing in a mixed diesel-electric railway network: a multi-corridor study from Kazakhstan

Rail freight route choice often combines distance, train-formation and operating rules without making the cost effects of heterogeneous traction explicit. This study evaluates a transparent, data-calibrated route-cost framework for strategic planning on Kazakhstan’s mixed diesel-...

Mitochondrial transcript abundance in breast cancer circulating tumour cells may reflect both blood-derived transcripts and biological heterogeneity

Circulating tumour cells (CTCs) are rare cells frequently profiled on a single cell level. A key indicator of single-cell transcriptome quality is the percentage of reads encoded by genes in the mitochondrial genome (MT-reads). No systematic data exists on MT-reads content in CTC...

Novel Antibacterial Hydrogels Incorporating Quaternary Ammonium Monomethacrylate: A Pilot Study on Swelling Behavior and Biological Analysis

Poly(acrylamide) (PAM) hydrogels offer biomedical potential, but bacterial colonization limits their long-term use. This study examines PAM hydrogels modified with quaternary ammonium monomethacrylate (QAHAMA-10) for antimicrobial properties. Five formulations with QAHAMA-10 to a...

High-Temperature Corrosion in Biomass and Waste-to-Energy Boilers: Mechanisms, Materials and Mitigation Strategies

Biomass and waste contain elevated concentrations of chlorine and alkali metals that promote the problem of high-temperature chlorine corrosion in power boilers. The results are rapid metal loss, increased maintenance costs, and reduced operational availability. This review paper...

Multiplicity Results for the Nonlinear Weighted Laplacian Equation on the Sierpiński Gasket

Abstract We study a Dirichlet problem driven by a weighted Laplacian on the Sierpinski gasket. Under suitable growth assumptions on the nonlinear term, we establish existence and multiplicity results by means of direct minimization, the mountain-pass theorem, and an abstract two-...

Redefining Last Glacial Maximum environmental conditions in northeastern Brazil: pollen-based evidence of open and moist-adapted vegetation cover

Limited continuous continental records and complex climatic interactions hinder a comprehensive understanding of paleoclimatic and paleoenvironmental conditions during the Last Glacial Maximum (LGM) in the tropics. Adjacent to the currently semi-arid northeastern Brazil (NEB), a...

Redox-active coordination catalysts for selective thermochemical valorization of biowaste: Mechanistic insights and structure-performance relationships

The growing demand for renewable energy has intensified global efforts to transform biowastes into value-added fuels and chemicals rather than viewing them as disposal challenges. Derived mainly from lignocellulosic and other organic residues, these wastes are rich in carbon and...

Behavioral Determinants of Prosumers’ Efficiency-Enhancing Changes in Energy Consumption Patterns

One of the key challenges of the contemporary solar energy market is matching supply and demand. The demand side of this problem largely depends on the difficult-to-predict, individualized, numerous, and dispersed behaviors of prosumers. With this in mind, the main objective of t...

Characteristics of Dust in Ventilation Air from Hard Coal Mine Exhaust Shafts and Its Implications for VAM Utilisation Technologies

Methane contained in ventilation air from hard coal mines (VAM, ventilation air methane) represents a significant environmental and technological challenge due to very large volumetric airflow rates and low methane concentrations. The feasibility of applying VAM utilisation techn...

Frequency-dependent shear and bulk viscosity of aqueous and non-aqueous lithium battery electrolytes

Transverse ultrasound was used to examine the frequency-dependent shear viscosities of three lithium bis(trifluoromethanesulfonyl)imide-based electrolytes: aqueous, non-aqueous, and hybrid aqueous-organic solutions. Frequency-dependent bulk viscosities of two of the electrolytes...
