The article presents the data related to the flame acquisitions in a liquid-fuel gas turbine derived burner operating in non-premixed mode under three different equivalence fuel/air ratio, which corresponds to a richer, an intermediate, and an ultra-lean condition, near lean blowout (LBO). The data were collected with two high speed visualization systems which acquired in the visible (VIS) and ...

Several facts regarding the structure of NGC 604 are examined here. The three main cavities, produced by the mechanical energy from massive stars which in NGC 604 are spread over a volume of 10 pc, are shown here to be undergoing blowout into the halo of M33. High resolution long slit spectroscopy is used to track the impact from massive stars while HST archive data is used to display the asymm...

We present new medium-resolution spectropolarimetric observations of HD 45677 in the B and R-bands. A change in polarisation is detected across Hα, Hβ and Hγ confirming that the ionised region around the star is aspherical. (Q,U) points associated with these emission lines occur away from the continuum, defining a polarisation vector which points in the same direction for each of the lines at a...

BACKGROUND AND OBJECTIVE To compare early and late surgical repair of orbital blowout floor fractures. PATIENTS AND METHODS A retrospective, comparative interventional case series reviewed medical records of 50 consecutive patients who underwent unilateral orbital floor fracture repair in a 4-year period. Comparative analysis was performed between patients operated on within 2 weeks of injury...

BACKGROUND AND OBJECTIVES The orbital floor may fracture alone, and the fracture is then defined as "pure"; when there is a rim involvement, the fracture may be defined as "impure". Controversy exists as to the pathophysiology of orbital floor fractures and the incidence of orbital rim involvement. The purpose of this retrospective review was to determine the incidence of purity in orbital floo...

To study the mechanism by which high-dimensional chaos emerges in neural systems, the synchronization of chaotic firings in class 1 pulse neural networks composed of excitatory and inhibitory ensembles was analyzed. In the system with two modules (i.e., two pulse neural networks), blowout bifurcation and on-off intermittency were observed when the inter-module connection strengths were reduced ...
