Downdraft Devices for Negative Emissions—Quantification Study and Environmental Implication

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Methane (CH4) is a potent greenhouse gas with a global warming potential far exceeding that of CO2 over short time horizons. Its removal from the atmosphere remains challenging due to its low ambient concentration and chemical stability. This study explores downdraft energy towers (DETs) as an innovative CH4 mitigation technology that enhances

Two Problems for the Political Inclusion of Animals

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT In recent years, the field of animal ethics has taken a political turn, with scholars arguing that sentient nonhuman animals should be included in the political sphere. This article explores two key challenges arising from this turn towards the political inclusion of animals: the Conflict Problem and the Numbers Problem.

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

open access: yesPolymer Composites, EarlyView.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Effect of wrap angle on performance of Pump As Turbine (PAT) in both pump and turbine modes

open access: yesIOP Conference Series: Earth and Environmental Science
Abstract Pump as turbine (PAT) is used in small hydropower plants to generate electricity for remote hill regions and the integration of other renewable resources. Generally, the efficiency of centrifugal pumps operating in turbine mode is low.

HOWLish: a CNN for automated wolf howl detection

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Automated detection of wolf howls presents a great opportunity for large‐scale passive acoustic monitoring of wolf populations. Here we present HOWLish, a CNN trained for automated wolf howl detection, based on thousands of hours of soundscapes recorded in the wild.
