We developed a two fluid atomizer to spray mammalian cells suspended in phosphate buffered saline (PBS)-Pluronic F-127 polymer solutions. We used the device to spray suspensions of bovine articular chondrocytes and porcine tracheal epithelial cells, in either PBS or the polymer solutions, and studied their viability and growth kinetics. Under the operating conditions examined in this study, the...

The present study was carried out to quantitatively analyze the levels of six potentially toxic heavy metals viz., arsenic (As), lead (Pb), cadmium (Cd), mercury (Hg), chromium (Cr) and nickel (Ni) in ten important Indian medicinal plants. The air dried powdered plant materials were subjected to microwave assisted wet digestion for the preparation of test samples. The samples were analyzed by u...

Allergic fungal sinusitis (AFS) is a stubborn disease requiring surgical and medical management. Delivery of topical medication is paramount in these patients, but the most difficult to accomplish. We investigated heavy irrigation (nasal douche) and atomized medication delivery potential in a cadaveric sinus model of polypoid AFS disease. Three disease models were created: a control that involv...

A number of analytical models predicting the size distribution of particles during atomization of Al-based alloys by N2, He and Ar gases were compared. Simulations of liquid break up in a close coupled atomizer revealed that the finer particles are located near the center of the spray cone. Increasing gas injection pressures led to an overall reduction of particle diameters and caused a migrati...

This paper presents an image-processing-based model for calculating the interfacial-area concentration (IAC) of a low-pressure microbubble (LPMB) scrubber, which facilitates determination operational conditions scrubber via flow-pattern analysis. The LPMB maximizes interfacial area two-phase systems using bubbly flow. Microbubbles have received attention due to their microscopic sizes, high res...

A simple technique is presented for the analysis for copper in small fragments of tissue. Dissolution of the tissue in concentrated nitric acid is the only preparative step required. Copper content is then determined by comparison with standards, by using the carbon rod atomizer previously described. Sample volumes of less than 2 d are used for each measurement. The method gives results that co...

Abstract We study the approach to calculating scale and shape parameters of Weibull droplet-size distribution by means skewness, kurtosis variance, obtained simulation atomization in an air-assisted atomizer with different viscosities, densities, flow rates surface tensions atomizing liquid. Such evades necessity determine shift parameter use approximation from calculation distribution. The maj...
