Helicoidal instabilities were recorded with a compact industrial mvBlueFox video camera and proprietary software to record the oscillations of the bubble.
The various types of bubble instabilities for PP can be classified as (1) draw resonance (DR), characterized by a periodic oscillation of the bubble diameter, (2) helicoidal instability, characterized by a helicoidal motion of bubble around its axial direction, and (3) FLH (frost line height) instability, characterized by variations in the vertical position of the FLH, as previously shown (Kim et al.
bonariensis species group is the general morphology of the sperm packages (as preserved in 80% ethanol), which display a strongly gnarled, helicoidal anterior region (Peretti & Battan-Horenstein 2003).
The company's timing and ability to recognize opportunities led to the introduction of SU diamond cutters, SpiraMax helicoidal cutter heads, advanced insert tooling, diamond/carbide hybrid tools, Procentrix, the new Generation Hogger, the Super Plus and many more.
Localised pressures, either ringed or spiral, allow the traqueal elements to be distended or stretched during the organ-lengthening process (Fahn 1995), and thus may explain the helicoidal root development.
Other features include CIP or SIP cleaning, solids washing cycles and unloading by means of gravity or helicoidal extractor.
1999) as well as its action in the hydroxylation of protein-bound proline and lysine, which provide stable triple helicoidal collagen through the embryonic stages (Barnes & Kodicek 1972).
This study suggests the potential usefulness of a novel urinary marker of bone resorption, HelP, a degradation product of the helicoidal region of type 1 collagen.
Designed to offer high torque per dollar in a small package, Series B Conex helicoidal gearmotors deliver up to 20 hp and maximum output torque to 5000 lb-in, with 10 standard ratios from 5:1 to 60:1.
One of the two film dispensers carries out helicoidal multi-layer wrapping with self-sticking stretch film starting from the upper edge of the pallet, while the other starts from the bottom.
Lakhtakia and Weiglhofer (1993) theoretically explored these proposed thin film helicoidal bianisotropic mediums (TFHBMs) with respect to the produced optical behavior in 1993.
