Application of Circular Economy Principles to Power Generation: Extending the Life of A Hydropower Plant by Pumped Hydro Energy Storage

Sustainable Development, EarlyView.
ABSTRACT The application of circular economy, which aims to maximize efficiency and reduce waste, to renewable energy sources necessitates, given the intermittent nature of the latter, robust energy storage solutions to ensure grid stability and avoid wasting energy.

Spatial analysis of PM_2.5 using a concentration similarity index applied to air quality sensor networks [PDF]

Atmospheric Measurement Techniques
Air quality sensor (AQS) networks are useful for mapping PM2.5 (particles with a diameter of 2.5 µm or smaller) in urban environments, but quantitative assessment of the observed spatial and temporal variation is currently underdeveloped.

Application research on slope deformation monitoring and earthwork calculation of foundation pits based on UAV oblique photography

IOP Conference Series: Earth and Environmental Science, 2020
Abstract The stability of foundation pit slopes is a key concern during the construction of foundation pits. The deformation and instability of slopes will pose a major threat to the safety of foundation pits construction. Based on the foundation pit project of Shenzhen Dapeng People’s Hospital, this study uses DJI phantom 4 RTK drone to

THE TERRITORIALIZATION OF ANGOLA'S REAL ESTATE FRONTIER: How Private‐led Housing Developments are Reshaping the Outskirts of Luanda

International Journal of Urban and Regional Research, EarlyView.
Abstract Africa is recognized as the final frontier for urbanization and capitalism. Following a long wave of massive loans to promote state‐led developments, small private foreign and local developers are transforming the urban landscape on the outskirts of Luanda, forging partnerships with Angola's national and local governments and developing an ...

Post-process correction improves the accuracy of satellite PM_2.5 retrievals [PDF]

Atmospheric Measurement Techniques
Estimates of PM2.5 levels are crucial for monitoring air quality and studying the epidemiological impact of air quality on the population. Currently, the most precise measurements of PM2.5 are obtained from ground stations, resulting in limited spatial ...

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.
