this paper presents results analyses of specific potential blowout scenarios for subsea oilpipelines between the coast of mainland of iran and khark island in the persian gulf. the analyses have been carried out with the sintef oil spill contingency and response (oscar) 3-dimensional model system.some hypothetical three-day blowout scenarios with light and heavy iranian oil have been investigat...
Ultrarelativistic-energy electron ring structures have been observed from laser-wakefield acceleration experiments in the blowout regime. These electron rings had 170-280 MeV energies with 5%-25% energy spread and ∼10 pC of charge and were observed over a range of plasma densities and compositions. Three-dimensional particle-in-cell simulations show that laser intensity enhancement in the wake...
Bluff-body flame instabilities are experimentally investigated under varying turbulence conditions during lean blowout. For all conditions, the blowout process is induced through a temporal reduction of fuel flow rate to capture flame-flow dynamics approaching Simultaneous high-speed particle image velocimetry (PIV), stereoscopic PIV, and C2*/CH* chemiluminescence imaging employed, along with a...
BACKGROUND Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital method. METHODS A retrospective review o...
The role of three-dimensional computed tomography in the management of maxillofacial bone fractures.
The findings of three-dimensional computed tomography (3DCT) and two-dimensional computed tomography (2DCT) with helical CT scanning were compared for 21 patients with maxillofacial bone fractures. The results of this study suggest that the 3DCT evaluation can be divided into 3 groups. The first group, in which 3DCT is superior to 2DCT, includes severe complicated midface fractures, for example...
