Abstract The impacts of climate change‐induced heat stress on workers are most prevalent in sectors with decent work deficits and this requires consideration for sustainable development. This paper focuses on the informal economy of brick kilns in India, a sector reliant on piece‐rate payments to its migrant labour force.

Abstract The amount and spatial distribution of surface displacement that occurs during an earthquake are critical information to the understanding of the earthquake source and rupture processes. However, the earthquake surface displacement occurs over wide regions, includes multiple components that affect the ground surface at different spatial scales,

Abstract Ionospheric molecular ions, such as N2+ ${\mathrm{N}}_{2}^{+}$, NO+, and O2+ ${\mathrm{O}}_{2}^{+}$, have been observed in Earth's high‐altitude ionosphere and the magnetosphere by several spacecraft missions. Their presence not only indicates that they obtain sufficient energy through effective energization mechanisms, predominantly during ...

Mapping with Pléiades - End-to-End Workflow
In this work, we introduce an end-to-end workflow for very high-resolution satellite-based mapping, building the basis for important 3D mapping products: (1) digital surface model, (2) digital terrain model, (3) normalized digital surface model and (4 ...

Abstract Mangroves are critically important ecosystems that are highly vulnerable to hurricanes. This study assessed the impact of Hurricane Maria on mangrove canopy heights and vegetation at two sites in Puerto Rico—La Parguera (southwest) and the Northeast Ecological Corridor (northeast)—and examined factors influencing recovery. Using remote sensing

Remote Sensing for Monitoring Macroplastics in Rivers: A Review
Panoramic of remote sensing platforms for monitoring plastics in riverine environments. Platform elevation is directly related to image spatial resolution; see the example of a plastic bottle captured from Unmanned Aerial Systems (UASs). Letters stand for drone (D) and satellite (S) platforms: (Sa) Sentinel‐2; (Sb) Sentinel‐1 SAR; (Sc) Pleiades ...

An Ethnomathematics Exercise for Analyzing a Khipu Sample from Pachacamac (Perú) [PDF]
A khipu sample studied by Gary Urton embodies an unusual division into quarters. Urton‟s research findings allow us to visualize the information in the pairing quadrants, which are determined by the distribution of Sand Z-knots, to provide overall ...
