Estimation of rainfall erosivity (R) using Geo-spatial technique for the state of Tripura, India: A comparative study

The Indian Journal of Agricultural Sciences, 2022
The principal-agent of soil detachment is rainfall kinetic energy (KE), which must be assessed to understand the nature of erosion, particularly in high rainfall regions, and is designated as a rainfall erosivity index (R).

Spectral Spatial Variation [PDF]

Scientific Reports, 2019
AbstractAutomatic carcinoma detection from hyper/multi spectral images is of essential importance due to the fact that these images cannot be presented directly to the clinician. However, standard approaches for carcinoma detection use hundreds or even thousands of features.

Effect of Fungus-Growing Termite on Soil CO2 Emission at Termitaria Scale in Dry Evergreen Forest, Thailand

Environment and Natural Resources Journal, 2021
Termites are one of the major contributors to high spatial variability in soil respiration. Although epigeal termite mounds are considered as a point of high CO2 effluxes, the patterns of mound CO2 effluxes are different, especially the mound of fungus ...
