Gas-filled microbubbles have been developed as ultrasound contrast and drug delivery agents. Microbubbles can be produced by processing surfactants using sonication, mechanical agitation, microfluidic devices, or homogenization. Recently, lipid-based oxygen microbubbles (LOMs) have been designed to deliver oxygen intravenously during medical emergencies, reversing life-threatening hypoxemia, an...

Solar radiation homogenizers are multi-mirror devices that try to reshape the solar distribution coming from a concentrator, so that, after passing through homogenizer, light flux becomes as much evenly distributed possible. The optical behavior of these multi-reflective is complex and still ill-understood. geometry concentrator defines features concentrated then characteristics particular homo...

A major factor that contributes to congestion on today’s freeways is the severe inhomogeneities of the traffic streams. If the traffic density can be controlled, congestion can be eliminated and delays can be reduced. This goal can be achieved by properly controlling the mean speed of traffic on each section of the freeway lane as well as the ramp entering rates. In this paper a fuzzy traffic d...

1. An improved type of ground glass homogenizer for soft tissues has been described which brings about a high degree of cell disruption and liberation of nuclei without causing appreciable damage to mitochondria. The gentleness and effectiveness of the new homogenizer in respect to isolation of mitochondria have been ascertained by comparing the ATP-ase activities of mitochondria isolated in 0....

HEK293 cell detergent-resistant membranes (DRMs) isolated by the standard homogenization protocol employing a Teflon pestle homogenizer yielded a prominent opaque band at approximately 16% sucrose upon density gradient ultracentrifugation. In contrast, cell disruption using a ground glass tissue homogenizer generated three distinct DRM populations migrating at approximately 10%, 14%, and 20% su...

Formulations containing engkabang fat and engkabang fat esters, F10 and E15 respectively were prepared using a high-shear homogenizer, followed by a high-pressure homogenizer. Both formulations were stable at room temperature, at 45 degrees C, and after undergoing freeze-thaw cycles. The particle sizes of F10 and E15 after high pressure were 115.75 nm and 148.41 nm respectively. The zeta potent...
