Wakes of towed and self-propelled bodies moving in stably stratified flows are of relevance to environmental and ocean engineering applications. To date, the majority of studies focused on the wakes of spheres and cylinders in stratified flows. Stable stratification modulates the wake dynamics, leading to a significantly different flow compared to non-stratified wakes. The wakes of spheres and ...

It has been shown by Stell [J. Stat. Phys., 63, 1203 (1991)] that at low temperature monodisperse sticky spheres collapse to form coexisting close-packed solid and infinitely dilute gases. We show that polydisperse sticky spheres also collapse and calculate the collapse temperature. The polydisperse spheres separate into fractions with narrower polydispersities which can then solidify. This is ...

Baited pesticide-treated biodegradable spheres were evaluated for their efÞcacy to control and monitor apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, R. mendax Curran, ßies. A Plexiglas pane treated with sprayable Tangle-Trap was found to be an effective technique for assessing the fate of Rhagoletis ßies encountering treated spheres. SigniÞcantly more R. pomonella and R. men...

Silicon possesses a high theoretical specific capacity and is promising high-performance anode material for lithium-ion batteries (LIBs). However, it shows poor cycling performance because of volume expansion. A hollow structure can improve Si performance, the template method one most common methods micro/nanosphere preparation. polystyrene (PS) microsphere has advantages having uniform control...

This study theoretically investigated detachment of homoaggregates and heteroaggregates attached on the planar surfaces at primary minima during transients in solution chemistry. The homoaggregates were represented as small colloidal clusters with well-defined structures or as clusters generated by randomly packing spheres using Monte Carlo method. The heteroaggregates were modeled as micropart...

To detect the growth in lesions, it is necessary to ensure that the apparent changes in size are above the noise floor of the system. By introducing a fiducial reference, it may be possible to detect smaller changes in lesion size more reliably. We suspend three precision spheres with a precision structure built from pieces from a popular children's building toy. We measure the distances betwee...

We examined the internal morphology, location of protein, and identity and location of elements, in avian urate-containing spheres in 9 species of birds. The urine spheres were collected from voided samples. The spheres ranged in size from 0.5-5.0 microm, except in the domestic fowl, where they ranged up to 10 microm in diameter. The internal morphology of the spheres was examined using freeze-...

The main goal is to obtain information about properties “pipe-layers” as quasi-continuous magnet virtue fact such step-b...

Numerical Vorono tessellation is used to investigate the mechanisms of frustration in some model glass systems. First, random packings of 8192 hard spheres of increasing volume fraction c are built in the at three dimensional space using an eecient computer algorithm. Their Vorono statistics evolves with c as if the system would like to reach a pure icosahe-dral order when extrapolating the vol...
