Creating surfaces capable of resisting liquid-mediated adhesion is extremely difficult due to the strong capillary forces that exist between surfaces. Land snails use this to adhere to and traverse across almost any type of solid surface of any orientation (horizontal, vertical or inverted), texture (smooth, rough or granular) or wetting property (hydrophilic or hydrophobic) via a layer of mucu...

Biosurfactants were found to be a suitable candidate for environment clean-up and as an alternative conventional treatment systems. In the present study, polyaromatic hydrocarbon degrading organism Bacillus halotolerans was screened its ability produce biosurfactant during degradation. The bio-surfactant activity of by using various methods like oil spreading technique, emulsification assay, fo...

The relationship between the binding of sodium n-dodecyl sulphate and protons to histone H1 has been investigated by equilibrium dialysis and titrimetry. The data cover the pH range 3.2-10 and surfactant concentrations up to 3.0×10-3 mol dm-3. A theoretical approach based on the binding potential concept of Wyman is presented and has been used to make estima...

In the present work, levofloxacin based microemulsion was developed and its usefulness as topical drug carrier system for anti bacterial activity was investigated. Microemulsion was prepared by phase titration method using oleic acid as oil phase, tween-60 as surfactant and isopropyl alcohol as co-surfactant. Five different formulations were formulated with various amount of the oil, water and ...

Bio-based waste materials are more often used as effective and cheap adsorbents to remove toxic organic compounds such dyes. Batch adsorption of C.I. Basic Blue 3 (BB3) onto Cladium mariscus saw-sedge was studied in comparison with sawdust obtained from various species wood order explore their potential application low-cost sorbents for basic dye removal wastewaters. The effect phase contact ti...

BACKGROUND Several concepts of treatment in neonatal ARDS have been proposed in the last years. The present study compared the effects of open lung concept positive pressure ventilation (PPVOLC) with a conventional ventilation strategy combined with administration of two different surfactant preparations on lung function and surfactant homoeostasis. METHODS After repeated whole-lung saline la...

In this paper, a Lagrangian particle method is proposed for the simulation of multiphase flows with surfactant. The model is based on the multi-phase smoothed particle hydrodynamics (SPH) framework of Hu and Adams [1]. Surfaceactive agents (surfactants) are incorporated into our method by a scalar quantity describing the local concentration of molecules in the bulk phase and on the interface. T...

in order to determine the effects of applied phosphate bio-fertilizer on yield and morphological traits of wheat, a research was conducted in sari agricultural sciences and natural resources university during 2008-2010. a factorial experiment was performed based on randomized complete block design with four replications. the first factor consists of two levels of phosphate bio-fertilizer (0 and...

This study examines surfactant dysfunction in rats with inflammatory lung injury from intratracheal instillation of hydrochloric acid (ACID, pH 1.25), small nonacidified gastric particles (SNAP), or combined acid and small gastric particles (CASP). Rats given CASP had the most severe lung injury at 6, 24, and 48 h based on decreases in arterial oxygenation and increases in erythrocytes, total l...
