Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Agrivoltaic Lettuce Production Under Future Climates: A Sustainable Strategy for Optimizing Food and Energy Yields

Sustainable Development, EarlyView.
ABSTRACT Food system resilience is increasingly challenged by climate change and global trade volatility, even in high‐income nations like Canada. Agrivoltaics—co‐locating crops and photovoltaics (PV)–offers a sustainable production strategy to optimize land use and address both food and energy security.

Calibration of simple clear-sky irradiance model coefficients across six climatic zones of South Africa

Journal of Energy in Southern Africa
This study applies a data-driven methodology to calibrate the coefficients of simple clear sky (CS) irradiance models for global horizontal irradiance (), diffuse horizontal irradiance () and direct normal irradiance () in South Africa.

A New Model for Estimating the Diffuse Fraction of Solar Irradiance for Photovoltaic System Simulations

Energies, 2017
We present a new model for the calculation of the diffuse fraction of the global solar irradiance for solar system simulations. The importance of an accurate estimation of the horizontal diffuse irradiance is highlighted by findings that an inaccurately ...

Renewable Resource Curse Hypothesis: Could Renewable Resources Foster Sustainable Development?

Sustainable Development, EarlyView.
ABSTRACT This study explores whether the resource curse hypothesis applies to renewable energy by introducing a novel metric of renewable resource rent. Using a panel dataset of 46 countries (2010–2022), we define renewable rent as the product of electricity generation and the gap between industrial electricity price and levelized cost (LCOE).

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

New Decomposition Models for Hourly Direct Normal Irradiance Estimations for Southern Africa

Solar
This research develops and validates new decomposition models for hourly direct Normal Irradiance (DNI) estimations for Southern African data. Localised models were developed using data collected from the Southern African Universities Radiometric Network

Integrating Chemical, Electrical, and Photonic Effects Into a Unified ETOP‐Based Plasma Dose Framework

High Voltage, EarlyView.
ABSTRACT In plasma medicine and biological applications, plasmas typically deliver a complex combination of reactive chemical species and multiple physical energy components. However, establishing a unified and comparable dose metric to characterise their integrated biological effects remains a major challenge that continues to limit progress in this ...

Configuration Optimisation of Integrated Wind–PV–CSP Power Generation to Enhance Grid Support in High‐Renewable Power Systems

IET Smart Energy Systems, EarlyView.
An 8760‐hour optimisation model is developed for integrated wind–PV–CSP systems. Full‐factorial configuration and sensitivity analyses identify a clear optimal structure under grid and turbine constraints, enabling balanced trade‐offs among economic performance, peak‐period supply capability and energy utilisation and providing practical references for

Site Fidelity, Depth Preference and Vertical Movement Patterns of Lentic and Lotic European Catfish Silurus glanis

Fisheries Management and Ecology, EarlyView.
ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...
