Chemical Composition of Apricot Pit Shells and Effect of Hot-Water Extraction [PDF]

Energies, 2015
Agricultural residues, such as corn stover, wheat straw, and nut shells show promise as feedstocks for lignocellulosic biorefinery due to their relatively high polysaccharide content and low or no nutritional value for human consumption.

INFORMATION EXTRACTION IN TOMB PIT USING HYPERSPECTRAL DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Hyperspectral data has characteristics of multiple bands and continuous, large amount of data, redundancy, and non-destructive. These characteristics make it possible to use hyperspectral data to study cultural relics.

Modelling marine sand extraction pit evolution: Exploring design parameter sensitivity and cohesive sediment effects

Environmental Modelling & Software
Marine sand extraction increases, calling for insight into the morphodynamic evolution of extraction pits and other bed forms, such as sand waves. We developed a quick, idealized, process-based numerical model to (1) simulate pit evolution; (2) quantify sensitivity to pit design parameters; (3) investigate interactions with cohesive sediment; and (4 ...

Stratification caused by sand extraction pits in coastal seas. [PDF]

Sci Rep
Abstract As demand for marine sand increases across the globe, large-scale seabed excavation in shallow shelf seas raises concerns about its impact on local hydrodynamics and ecosystem functioning. In the Netherlands maritime area of the North Sea, deep sandpits excavated for coastal protection, beach nourishment, and infrastructure ...
