The effect of concentration polarization is analysed, and the effect of feed and osmotic sink velocity on the performance of the osmotic dw has also been studied.

Sea water acidification affects osmotic swelling, regulatory volume decrease and discharge in nematocytes of the jellyfish Pelagia noctiluca. Full Text Available Effective diffusivities of watersucrose and minerals in osmotic treatment of pork cubes M.

As the membrane permeability determines the HOP process feasibility, this paper also describes the effect of the interaction between the fluid and the membrane on the system efecot. For above conditions of osmotic dehydration, average effective diffusivity of water loss and solute gain varied from 2.

The better material properties of hydrogels in vivo than in vitro evaluation demonstrated their potential application in cartilage replacement. The osmotic gradient is known to be one of the major determinants of water transport.

Gibbs–Donnan effect

Findings from this study show the potential role of seed priming with biostimulants in the alleviation of abiotic stress conditions during seed germination and seedling growth in C. However, the efficiency of these technologies is hampered by fouling phenomena.

An attempt to understand the mechanism of water permeation under osmotic and hydrostatic gradients has been made based on the irreversible thermodynamic approach.

Most of these studies have been limited to greenhouse or container-grown plants. Zugarramurdi and Lupin’s model was used to predict the equilibrium condition, which was shown to be appropriate for water loss and solute uptake during osmotic treatment. Osmolality was consistently greater by freezing point osmometry than by vapor pressure osmometry.

A simple experimental setup has been used and hereby introduced. Basic helix-loop-helix bHLH leucine-zipper transcription factors play important roles in abiotic stress responses. Further studies discovered that other cut in biosynthesis mutants are also impaired in osmotic stress induction of ABA biosynthesis genes and are sensitive to osmotic stress.

Seed priming increases seed water content, improves protein synthesis using mRNA and DNA and repair mitochondria in seeds prior to germination. Osmotically driven membrane process for the management of urban runoff in coastal regions.

The parameters of this Archer extension of Pitzer model were found from this data fitting. The purpose of this donnsn was to build an expert system for the development and formulation of push-pull osmotic pump tablets PPOP. The Gibbs—Donnan effect also known as the Donnan’s effectDonnan lawDonnan equilibriumor Gibbs—Donnan equilibrium is a name for the behaviour of charged particles near a semi-permeable membrane that sometimes fail to distribute evenly across the two sides of the membrane.

For all tested amino acids, the osmotic coefficients are lower when the TIP3P water model is used. Directory of Open Access Journals Sweden. The fruit to solution ratio was kept 1: After pretreatment by pH adjustment, the flux recovery dinnan to Reviving the Ganges Water Machine: Views Read Edit View history.

Effective moisture diffusivity of water as well as solute was estimated using the analytical solution of Fick’s law of diffusion. Both species, subjected to the same environmental conditions, showed a resembling daily pattern in simulated osmotic storage water potential.

In Chapter 5, self-assembly behavior of natural silk fibroin within the gland of Bombyx mori silkworm was investigated using osmotic. This trait is compatible with productivity, but requires available soil moisture. In contrast, the SOS sample produced hydrochar with no definite particle shape but with a raspberry-like surface. gibb

Studies on osmotic concentration of radioactive effluents. Quantification of osmotic water transport using Alexa Fluor albumin closely correlated with direct volumetry and with estimations based on radioiodinated I serum albumin RISA. A solute donann present at the pore mouth can either be reflected or permeate the pore.
