Weathering deterioration in pre-harvest of soybean seeds: physiological, physical, and morpho-anatomical changes

Scientia Agricola, 2021
: Successive cycles of water absorption and loss favor weathering deterioration, one of the main factors that affect the quality of soybean seeds. This study evaluated the physiological, physical, and morpho-anatomical changes in soybean seeds under ...

Reservoir theory for studying the geochemical evolution of soils [PDF]

, 2010
[1] Linking mineral weathering rates measured in the laboratory to those measured at the landscape scale is problematic. In laboratory studies, collections of minerals are exposed to the same weathering environment over a fixed amount of time. In natural

Influence of accelerated ageing on the physico-mechanical properties of alkali-treated industrial hemp fibre reinforced poly(lactic acid) (PLA) composites [PDF]

, 2010
30 wt% aligned untreated long hemp fibre/PLA (AUL) and aligned alkali treated long hemp fibre/PLA (AAL) composites were produced by film stacking and subjected to accelerated ageing. Accelerated ageing was carried out using UV irradiation and water spray

Chemical weathering of the volcanic soils of Isla Santa Cruz (Galápagos Islands, Ecuador) [PDF]

, 2014
We present a study on weathering of volcanic soils using 43 profiles (131 horizons) sampled in Santa Cruz Island (Galapagos Islands). Several weathering indices, based on chemical composition, are used. Since the geological material is highly homogeneous

Structure of supercritically dried calcium silicate hydrates (C-S-H) and structural changes induced by weathering [PDF]

, 2013
The nanostructure of supercritically dried calcium silicate hydrates was researched. This particular drying procedure was used to avoid nanostructure modifications due to conventional drying processes.
