With polylactic-co-glycolic acid(PLGA) as shell material of microcapsule, amoxicillin as the model, poly(vinyl alcohol) and twain as surfactant, amoxicillin-PLGA microcapsules were manufactured using digital micro-jetting technology and a glass nozzle of 40μm diameter. The influences of the parameters of micro-jetting system on the mean grain size and size distribution of amoxicillin-PLGA micro...

This paper presents a feature analysis of two electromagnetic interference test facilities. The one is an anechoic chamber and the other is a reverberation chamber. And then, this paper reviews problems of the current reverberation chamber, the stirrer. In general, a reverberation chamber uses a stirrer to generate a uniform electric field inside it. However, the stirrer is a big sized unit and...

The “Development of Operating Model for the Design Stirrer Arms Slurries: Empirical Evaluation Arms” is reported. Previous work reviewed “Operating Slurries” and identified Two Z TETE stirrer arms as most effective. Furthermore, subsequent Fabrication designed fabricated arms, evaluated theoretical (expected) Slurry Mixing Power Order Merit Analysis. current did empirical evaluation also hybrid...

Vegetable oil bio-based lubricants are regarded as a suitable alternative to petroleum-based due the increasing environmental concerns in past years. This study presents sunflower oil's viscosity and tribological properties with additions containing 0.25 1% weight percentage ZnO nanoparticles. The magnetic stirrer ultrasonicator were used prepare samples of lubricants. Redwood viscometer is mea...

This paper reports work on the two and three-dimensional numerical simulation of dough mixing with free surfaces, that arises in the food processing industry. Free surface flow in a rotating cylinder is investigated when a fluid is mixed in a cylinder with a stirrer. Different dough mixer designs are investigated. The rotating stirrer may be placed either in a concentric or eccentric arrangemen...

Environment-friendly “green” nanocomposites were fabricated from a starch-based, dispersion-type biodegradable resin and cellulose nanofibers. The mixture of the dispersion-type biodegradable resin and cellulose nanofibers were blended well by using a mixer and/or a stirrer. Composites were prepared by conventional hot pressing at a constant temperature of 140oC and at pressures from 10 to 50 M...
