Summary The Green & Ampt infiltration analysis is applied to the problem of the water uptake by aggregates when they are surrounded by water. Two situations are analysed, namely, when there is free escape of the displaced air and when there is no escape of the air.

The Role of Seed Characteristics on Water Uptake Preceding Germination
SeedsSeed germination is a complex process involving imbibition, activation and subsequent growth. In addition to re-establishing metabolic activity, water uptake helps stabilize macromolecules and biochemical reactions, resulting in radicle protrusion ...

Water uptake in the intact frog
American Journal of Physiology-Legacy Content, 1963The effects of potassium depletion, calciferol-induced hypercalcemia, hyaluronidase, hypercapnia, and adrenal steroids on the water uptake of intact frogs were studied. The findings suggest that potassium depletion and hypercalcemia interfere with water uptake.

Kinetics of wheat flour water uptake
Nahrung/Food, 2002The kinetics of wheat flour water uptake at 15, 25, 35 and 45 degrees C and different relative humidities from 43.2 to 85.9 was investigated. The water uptake curves obtained were well described by the first-order kinetics equation. A suitable general empirical model was found that includes the effect of temperature and relative humidity.

Water uptake by some chamber materials
Plant, Cell and Environment, 1982Abstract. The characteristics of water uptake by several materials have been studied. Nitrile rubber, silicone rubber and perspex retained substantial quantities of water. Metals took up smaller, but still significant, amounts of water, and glass was the least water-retentive material used in the tests.

Water Uptake Mechanism in Crispy Bread Crust
Journal of Agricultural and Food Chemistry, 2008Crispness is an important quality characteristic of dry solid food products such as crispy rolls. Its retention is directly related to the kinetics of water uptake by the crust. In this study, a method for the evaluation of the water sorption kinetics in bread crust is proposed. Two different sorption experiments were used: an oscillatory sorption test

Performance and prospects of different adsorbents for phosphorus uptake and recovery from water
, 2020The need to control eutrophication in water bodies and the risk of supply shortage of phosphate rock have motivated the search for treatment techniques able to sequester and recover P from wastewaters. Current techniques can recover phosphate from highly

Nonlinear Root-Water Uptake Model
Journal of Irrigation and Drainage Engineering, 1996Sound irrigation management requires information about root-water uptake patterns of different crops. In the existing literature, the extraction rate of soil moisture by the roots is assumed to be either constant or varying linearly with the root depth, during the crop period. However, both these models have limited application.

Plants uptake water from the soil through their roots to ensure their biosynthesis and transpiration. This chapter describes the sequence of processes along the transport path of water during water uptake: supply of water from the soil to the roots, water absorption by the root and finally the long distance transport of water through the vascular ...
