in this paper, the effects of several factors such as surfactant concentration, solute concentration, impeller speed and holdup on the mean drop diameter ( ) during emulsification have been studied in a single-stage mixer-settler extractor. a video technique has been developed in order to measure drop size distribution in the mixing chamber using a digital camera. the results show decreases wit...

Our previous description of solute drag on a synthetic membrane has been extended to include the solutes mannitol, sucrose, raffinose, inulin, and dextran. Labeled and nonlabeled forms of these solutes were used in pairs to quantitate solute flux interaction. Three membranes with pore sizes of 350, 80, and 20 A, respectively, have been utilized. It is shown that solute flux interaction occurs w...

Ice-templating has become an increasingly popular synthetic tool in the materials science community. In this review, we focus on role of solute–freezing front interactions, and particularly solute–solute determining self-assembled structure that results from ice templating.

A stream solute workshop was held February 1-5,1989, at The University of Mississippi with the goals of 1) suggesting a conceptual model for stream solute studies that integrates physical, chemical, and biological processes, and 2) identifying advantages and limitations of various methods for studying solute transport and exchanges. Solute dynamics refers to the spatial and temporal patterns of...

Recently in this laboratory the conductometric measurement of aqueous solutions Li, Na and K salt L-leucine were studied at different temperature molar concentration to investigate solute-solvent, ion-solvent interactions (solute means drug) also effect dilution was investigated. During work thermodynamic parameters (change free energy, change entropy enthalpy) investigated concentrations range...

Solute carriers are eukaryotic membrane proteins that control the uptake and efflux of solutes, including essential cellular compounds, environmental toxins, and therapeutic drugs. Solute carriers can share similar structural features despite weak sequence similarities. Identification of sequence relationships among solute carriers is needed to enhance our ability to model individual carriers a...

a book review is presented on numerical simulation of groundwater flow and solute transport, edited by l. elango, published by allied publishers pvt. ltd. in 2005, 245 pp, hardback isbn 81-7764-923-x.

many mathematical models have been applied and developed for simulation of water and solute transport in irrigated agriculture. using a model, it should be first calibrated and validated for different regions. swap is a field scale model that simulates water, solute and heat movement in the soil profile. in this study, the swap model was evaluated for two years (2001 and 2002) on wheat in a sem...

When phospholipid vesicles bound to a planar membrane are osmotically swollen, they develop a hydrostatic pressure (delta P) and fuse with the membrane. We have calculated the steady-state delta P, from the equations of irreversible thermodynamics governing water and solute flows, for two general methods of osmotic swelling. In the first method, vesicles are swollen by adding a solute to the ve...
