Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

Fine Particulate Matter Constituents, Ozone, and Systemic Lupus Erythematosus: A Large General‐Population Cohort Analysis With Extended Quantile g‐Computation

Arthritis &Rheumatology, EarlyView.
Objective The aim of this study was to investigate whether exposure to mixture of individual fine particulate matter (PM2.5) chemical constituents is associated with incident systemic lupus erythematosus (SLE) and if ozone modifies this association and/or is associated with SLE onset.

On the Suitability of MODIS Time Series Metrics to Map Vegetation Types in Dry Savanna Ecosystems: A Case Study in the Kalahari of NE Namibia

, 2009
The characterization and evaluation of the recent status of biodiversity in Southern Africa’s Savannas is a major prerequisite for suitable and sustainable land management and conservation purposes.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Trends in vegetation productivity and seasonality for Namaqualand, South Africa between 1986 and 2011: an approach combining remote sensing and repeat photography

, 2013
This thesis presents an assessment of vegetation change and its drivers across a subset of Namaqualand, South Africa. Namaqualand forms part of the Succulent Karoo biome, which is characterised by exceptionally high species biodiversity but which has ...

Potassium hydroxide activation of microalgal biochar for improved adsorption efficiency

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Activated carbon was prepared from Chlorella by carbonization and potassium hydroxide activation, and its structural properties and methylene blue (MB) adsorption performance were evaluated. Raw Chlorella exhibited an adsorption capacity of 287.2 mg g−1, which decreased to 214.8 mg g−1 after carbonization.

Correlation Analysis of RGB Image-Based Vegetation Indices to Chlorophyll Content in Leafy Vegetables with Nutrient-Stressed Condition

Jurnal Keteknikan Pertanian Tropis dan Biosistem
Nutrient stress is one of the main factors affecting the growth and productivity of leafy vegetables. Chlorophyll content is often used to indicate plant nutrient status, but conventional measurement methods are destructive and inefficient.

A curated review of ESA publications for teaching ecology

The Bulletin of the Ecological Society of America, EarlyView.
Abstract Since the early 1990s, the Ecological Society of America's journals have published hundreds of articles of direct relevance to those who teach ecology—especially at the undergraduate level. In an effort to draw attention to that literature, we conducted an analysis to identify well‐cited articles, as well as those that may be underrecognized ...
