were assayed for recall proliferative response to OVA 323-339. Emulsions prepared by either the dual-syringe or sonification method stimulated a strong T-cell response, as demonstrated by the ex vivo proliferation assay. A likelihood ratio test indicated a stronger immunization with the sonified emulsion transferred by the method outlined above than with the emulsion prepared by the dual-syring...

Herein it was found that CO(2) could trigger an O/W to W/O emulsion inversion via a W/O/W nanoemulsion. In comparison with the conventionally used liquid or solid additives, the unusual advantage of this method is that the emulsion morphologies can be switched reversibly by the control of CO(2) pressure. Besides, CO(2) can be easily removed by depressurization and thus no extra separation proce...

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...

Many on-chip approaches that use flow-focusing to pinch the continuous aqueous phase into droplets have become the most popular methods that provide monodisperse emulsion droplets. However, not every lab can easily adapt a microfluidic workflow into their familiar protocols. We develop an off-chip approach, spinning micro-pipette liquid emulsion (SiMPLE) generator, to produce highly stable mono...

This study is about the non-uniform electric field for splitting of water in oil emulsion. If the process occurs in an inhomogeneous electrical field, the drops are polarized and then their mobility is increased. The emulsion drops will be charged and move toward the central point of splitter where the maximum intensity of electrical field has been concentrated. In this process, the drops encou...

This thesis demonstrates the feasibility of using a medial surface transformation as a tool to rapidly approximate the solidification patterns of convex faceted solid models of castings. The medial surface transformation is used to automate the greatest included sphere approach to solidification pattern approximation. The experimental software of this thesis extracts the medial surface transfor...

Water-in-oil emulsions are commonly used to provide persistent release of antigens necessary for sustained stimulation of the immune system. Optimal response of an animal's immune system is dependent upon repeated, maintained exposure to the antigen. The sustained release of antigen, which delays catab-olism, is thought to be one of the major methods by which adjuvants enhance the immune respon...

OBJECTIVE To assess the effect of captopril, an angiotensin-converting enzyme inhibitor, on the metabolism of chylomicrons and their remnants and the possible alterations in the concentrations of plasma lipids caused by the drug in hypertensive hypercholesterolemic individuals. METHODS The metabolism of chylomicrons was tested with the method of artificial lipid emulsion of chylomicrons label...

Laser Engineered Net Shaping (LENSTM) is a rapid-manufacturing process that involves complex thermal, mechanical, and metallurgical interactions. Due to process input parameter such as laser power , laser scanning velocity and feed rate, the effect on solidification of component to be produced must be understand. The finite element method (FEM) may be used to accurately model this process and s...
