This study evaluated the loss of desiccation tolerance in C. langsdorffii seeds during the germination process. Seeds were imbibed for 24, 48, 72, 96, 120 and 144 hours and dried to the initial moisture content, kept in this state for 3 days after which they were submitted to pre-humidification and rehydration. Ultraestructural evaluations were done aiming to observe the cell damage caused by t...

The movement of water into harvest-ripe grains of dormant and non-dormant genotypes of wheat (Triticum aestivum L.) was investigated using Magnetic Resonance Micro-Imaging (MRMI). Images of virtual sections, both longitudinal and transverse, throughout the grain were collected at intervals after the start of imbibition and used to reconstruct a picture of water location within the different gra...

Swelling parameters were determined for 15 seed species; the swelling quotients were found to range from less than 1.1 (castorbean) to 2.8 (mungbean) and swelling coefficients ranged from 0.09 (castorbean) to 0.42 (cowpea). Swelling leads to a lowering of specific gravity of those seeds with high initial specific gravity, and an elevation of those with low initial specific gravity. The extent o...

The wharf roach Ligia exotica is a small animal that lives by the sea and absorbs water from the sea through its legs by virtue of a remarkable array of small blades of micron scale. We find that the imbibition dynamics on the legs is rather complex on a microscopic scale, but on a macroscopic scale the imbibition length seems to simply scale linearly with elapsed time. This unusual dynamics of...

The type of solid substrate plays a critical role in determining the kinetics spray fluidized bed (SFB) agglomeration process. In case porous (also soft) primary particles (PPs), droplet aging is due to imbibition and drying. surface properties also change imbibition. focus present work simulate spray-dried milk powder using Monte Carlo (MC) method coupled with drying-imbibition model. order ex...

“Fracturing network+imbibition oil production” is a new attempt to effectively develop low-permeability tight reservoirs. Fracturing fluid not only carrier for sand carrying but also tool in the process of imbibition. On basis imbibition experiments, combined with nuclear magnetic resonance and pseudo-color processing technology, this paper clarified dominant forces different types pore-throat ...
