Orbital floor fracture due to vigorous nose blowing in the absence of mechanical trauma is rare, only four cases having previously been reported. In each of these cases, predisposing factors have been identified; preceding URTI in three and a history of sino-nasal surgery in the fourth case. We present the case of a 49-year-old woman who developed a maxillary sinus fracture and orbital emphysem...

The self-guiding of relativistically intense but ultrashort laser pulses has been experimentally investigated as a function of laser power, plasma density, and plasma length in the blowout regime. The extent of self-guiding, observed by imaging the plasma exit, is shown to be limited by nonlinear pump depletion with observed self-guiding of over tens of Rayleigh lengths. Spectrally resolved ima...

Shell must cease drilling well before the water freezes over lest a late-season blowout cause oil to accumulate under the ice through the winter.

The Whitehead Minimization problem is a problem of finding elements of the minimal length in the automorphic orbit of a given element of a free group. The classical algorithm of Whitehead that solves the problem depends exponentially on the group rank. Moreover, it can be easily shown that exponential blowout occurs when a word of minimal length has been reached and, therefore, is inevitable ex...

It is shown that bright cluster dwarf ellipticals follow a relation between metallicity and apparent flattening. Rounder dwarfs tend to be more metal-rich. The evidence is based on colour as well as spectroscopic line-strength data from the literature. The large scatter of dEs around the mean metallicity-luminosity relation, usually ascribed to large observational errors, turns out to be an ell...

Objectives: The aim of the current study was to determine whether, using Hess area ratio for an objective measurement ocular motility, orbital blowout fractures should be surgically repaired. Methodology: 200 consecutive patients with were involved in this retrospective analysis (mean age: 27.0 years; range: 7-65 150 males; 50 females). Between March 2009 and September 2017, all received fractu...

PurposeOur study purpose was to clarify the extent of isolated unilateral orbital blowout fracture in relation surgical treatment and other factors behind decision. The specific aim determine which computer-aided measurements based on radiological images associate with choice.MethodsA retrospective cohort implemented patients an fracture.
