Directory of Open Access Journals Sweden. In FO, water is extracted from a feed solution using the high osmotic pressure of a hypertonic solution that flows on the opposite side of a semipermeable membrane; however, solutes diffuse simultaneously through the membrane in both directions and may jeopardize the process. Full Text Available Osmotic treatment of the fish Carassius gibelio was studied in two osmotic solutions: The model was tested in aquaporins heterologously expressed in Xenopus oocytes.

The current study aimed to determine the role of biostimulants-seed-priming during germination and seedling growth of Ceratotheca triloba Bernh. Using a numerical implicit model for root water extraction by a single root in a symmetric radial flow problem, based on the Richards equation and the combined convection-dispersion equation, we investigated some aspects of the response of root water uptake to combined water and osmotic stress.

Finally, it was concluded that the. Moreover, the as-consolidated alumina bodies were partially drained of fluid during the osmotic consolidation process, producing cohesive partially dried bodies with improved handling characteristics.

To make such osmocapsules, water-in-oil-in-water double-emulsion drops with ultra-thin shells are prepared as templates through emulsification of core-sheath biphasic flow in a capillary microfluidic device. However, the efficiency of these technologies is hampered by fouling phenomena.

Osmotic consolidation of suspensions and gels. Condensate water samples were collected from a few locations in Saudi Arabia and detailed characterizations were conducted to determine the quality of this water.

Osmotic adjustment and low osmotic potential are considered compatible with growth and yield because they aid in the maintenance of leaf turgor.

Some ionic species can pass through the barrier while others cannot. Osmotic adjustment in Rasol and Unknown11 were highest 0. The quantification of the soil water potential is necessary for a variety of applications both in agricultural and horticultural systems such as optimization of irrigation volumes and fertilization. Die-off rates were The objective of this study was to characterize isolates of M. Full Text Available Drought is one of the most important environmental stresses that highly affect crop growth and yield.

Here, we describe a new approach to derive operational parameter settings for osmotic power plants using a pressure exchanger for optimal performance, either with respect to maximum generated power or maximum extracted energy. Ultrasound irradiation could increase the mass transfer coefficient. Testable hypotheses are developed to predict the conservation potential of a subsidy in real-world application. Evidence of independent action of neurohypophyseal peptides on osmotic water flow and active sodium transport in the same target organ: The results showed that drought-stressed plants of both cultivars showed a decrease in leaf relative water content RWC and osmotic potential in the functional leaves and developed osmotic adjustment with an increase in the contents of free amino acids, soluble sugars, inorganic K, and nitrate as compared to well- watered plants.

Then, designing the new EOP tablet and investigating the effect of different variables of core and coat formulations on drug release behavior by single parameter optimization and by Taguchi orthogonal design with analysis of variance ANOVA, respectively. An osmotically active solute obeys a advection-diffusion equation in a region demarcated by a deformable membrane.

Gibbs–Donnan effect – Wikipedia

RWC in three independent times, leaf rolling, leaf silvering, days to flowering, days to maturity and stem reserve remobilization were investigeted. Hundreds of PPOP formulations were studied according to different poorly water -soluble drugs and pharmaceutical acceptable excipients. Influence of biostimulants-seed-priming on Ceratotheca triloba germination and seedling growth under low temperatures, low osmotic potential and salinity stress.

Osmotic water transport across the peritoneal membrane is applied during peritoneal dialysis to remove the excess water accumulated in patients with end-stage renal disease. The feasibility hibbs using RO retentate from a municipal water recycling plant was examined from two aspects: Furthermore, immunocytohistological studies, using JIM5 and JIM7 antibodies, revealed a decrease of labeling of both low- and high-methylesterified pectins in this maize line.

Here, we present a numerical method that allows for studying the interplay between diffusive, osmotic and mechanical effects.

We studied the magnitude and rate of givbs diameter change in response to decreasing apoplastic water potential and the role of living parenchyma cells in it to better understand xylem diameter changes in different environmental conditions. Furthermore, the extent of changes in transpiration rate was similar to the changes in Kplant and Lp. From the experimental osmotic coefficient value we have estimated the critical micellar concentration cmc of ILs in water.

Although there was a clear correspondence of genetic groups to water groups; these responses efectk important features in the search for alternative management in black bean pathosystem. There were groups of isolates that were tolerant to water stress induced. Osmotic stress on nitrification in an airlift bioreactor.

The numerical method is based ddonnan an immersed boundary method for fluid-structure interaction and a Cartesian grid embedded boundary method for the solute.

The equilibration method that measures osmotic pressure relative to a reference with known osmotic pressure was introduced. Water potential in soil and Atriplex nummularia phytoremediator halophyte under drought and salt stresses. Hydration is the most important external factor for seed germination. Most of these studies have been limited to greenhouse or container-grown plants.

In many instances, from ultrafiltration of proteins to ion exchange chromatography, the pH of the buffer adjacent to the charged groups of the membrane is different from the pH of the rest of the buffer solution. For all tested amino acids, the osmotic coefficients are lower when the TIP3P water model is used.

The water potential magnitudes favored water movement from the parenchyma to the chlorenchyma xonnan the end of the night and in the reverse direction during the late afternoon. Seed priming increases seed water content, improves protein synthesis using mRNA and DNA and repair mitochondria in seeds prior to germination.
