imbibition

 [im″bĭ-bish´un]
absorption of a liquid.

im·bi·bi·tion

(im'bi-bish'ŭn),
1. Absorption of fluid by a solid body without resultant chemical change in either.
2. Taking up of water by a gel, thereby increasing its size.
[L. im-bibo, to drink in (in + bibo)]

im·bi·bi·tion

2. Taking up of water by a gel.

imbibition

The taking up of fluid as by absorption into a gel.

imbibition

the uptake of water by, for example, the dry seed, that causes GERMINATION to start. The process is due, not to SELECTIVE PERMEABILITY through a membrane, but rather to the property of water ADSORPTION by colloidal particles such as cellulose, pectin and cytoplasmic proteins, using chemical and electrostatic attraction.

The present study observed the initial germination, as evidenced by cotyledon petiole protrusion in T1 and T2, on the 18th day (432 hours), and in T3 and T4 on the 12th after the beginning the test (288 hours), characterizing phase III of imbibition.
However, after scarification, under the same conditions, the peroxidase activity already increased (1.55umol x [min.sup.-1] x [mg.sup.-1]) within 2h, and during imbibition the activity declined.
This result confirms that seed imbibition in the -0.4 MPa treatment was not satisfactory to efficiently activate the metabolism of the germination process, corroborating the results for germination percentage and shoot length (Table 2), characterizing the -0.4 MPa level as critical for germination and initial development of cowpea seedlings, limiting imbibition and degradation of seed reserves.
Other areas that have recently caught interest due to their importance in understanding the fluid behavior in shale or increasing the productivity are (i) spontaneous imbibition in shales [218, 223-225], (ii) thermodynamic phase behavior of fluids inside shales as a function of pressure drawdown during production [226-231], (iii) alternate fracturing fluids [232-237] for better reservoir stimulation and to avoid water usage, and (iv) enhancing oil recovery by injection of fluids [238-240].
Therefore, the characteristics of the nonlinear seepage cannot be ignored in the study of imbibition of tight cores [22].
For imbibition, the base is raised until the lower 1-2 mm of the sample is submerged in the fluid.
Compared to figures in literatures [58], simulated capillary pressure data demonstrated that standard wettability tests (Amott-Harvey and free imbibition) may give misleading results when the sample was fractionally wet in nature [58].
Higher activity of the enzymes [alpha]-amylase, protease and dehydrogenase during imbibition. Shine et al.
Different peaks of ethylene evolution were observed after the beginning of imbibition in cucumber seeds while ethylene emission was increased with passage of time.
In first phase imbibition', dormant seeds uptake water thus increasing in volume and enzymatic activity.
This work focuses on assessment of the Hill equation's ability to predict the process of spontaneous imbibition of a porous material with "oil-in-water" emulsions and to compare its adequacy with both the classical and modified Washburn equation.
