BACKGROUND Triolein emulsion infusion into the brain produces transiently increased vascular permeability. OBJECTIVES The purpose of this study was to find the minimum percentage of triolein emulsion required for studying vascular permeability with minimal brain edema. MATERIALS AND METHODS Sixty healthy cats were divided into six groups according to the concentration of emulsified triolein...

The distinctive features of limited solubility in liquid eutectic and monotectic metallic systems have been discovered. The monodispersed emulsion model has been elaborated for a description of the specific microheterogeneous structure of eutectic melts. It includes the transitional shells (TS) at the interface boundaries having the eutectic composition and the closest packing of atoms. By mean...

This study examined whether combining lipid emulsion and advanced cardiac life support (ACLS) improves survival in an unanesthetized swine model of bupivacaine- and hypoxia-induced cardiovascular collapse. Arterial and venous catheters and a tracheostomy were surgically placed in 26 swine receiving inhalation anesthesia. After a 1-hour recovery period, bupivacaine (5 mg/kg) was administered int...

−− Time optimal monomer and reactor temperature set-point profiles were computed and implemented experimentally for the control of copolymer composition and minimization of reaction time in emulsion copolymerization systems. Iterative Dynamic Programming (IDP) was used for the offline calculation of the optimal profiles. This approach can deal with constrained optimization of systems described ...

extraction of nickel and its co-extraction with copper from ammoniacal media into emulsion liquid membrane systems (elms) was investigated using lix 84i as the carrier. measurement of the solute stripped in the internal phase of emulsion opened a new dimension in the study of the elm extraction processes. the effect of operating parameters such as feed ph, initial feed concentration, and treat ...

In this paper we review some recent results, obtained jointly with Stu Whittington, for a mathematical model describing a copolymer in an emulsion. The copolymer consists of hydrophobic and hydrophilic monomers, concatenated randomly with equal density. The emulsion consists of large blocks of oil and water, arranged in a percolation-type fashion. To make the model mathematically tractable, the...

An emulsion is a two-phase liquid system of two immiscible liquids, where the liquid with lower mass fraction is dispersed in form of small droplets in other surrounding liquid of higher mass fraction. Emulsions are widely used to produce sol–gel, drugs, synthetic materials, and food products. Based on the size of droplet, emulsions can be classified as micro and macro emulsion. Karbstein and S...
