traumatic false aneurysm of the thoracic aorta is not uncommon. but accordingly this case is unusual in its ten year delay between injury and presentation and treatment. a victim of the iran-iraq war is presented with a false aneurysm of the thoracic aorta ten years after a bullet injury to the chest and thoracic spine. penetrating chest wounds, mechanisms of injury and diagnosis are also discu...

Long Island glacigenic surface deposits, where exposed, are ideal for geologic field studies of Pleistocene glacial settings. Numerous outcrop exposures, found scattered throughout the island, delineate many of the deposit types associated with a full spectrum of glacial facies currently observable at active continental ice sheet margins. By directly field sampling axial orientations of a numbe...

iran is well known for having countless historical and instrumental records of tectonic events. shahriary catchment, as a study area, is part of the zagros collision seismic province. this research aimed to introduce a new method which is useful in identifying the relative active tectonic events of an area. the research method was designed in order to calculate the relative active tectonic inde...

[1] The tectonic evolution of Mars has been driven primarily by the interaction of Tharsisinduced loading stresses with a uniform contractional stress field, leading to global assemblages of graben and wrinkle ridges. Until recently, strike-slip faults have appeared to be largely absent from the tectonic record. We here present evidence for a new set of Noachian to Early Hesperian strike-slip f...

[1] Climate change indirectly alters the distribution of tectonic uplift at active orogens by modifying the action of surface processes, which in turn alters mountain topography. The impact of alpine glaciation on tectonic activity is explored here. The predictions of previous analytical, critical wedge models are compared with the output of a numerical model that explicitly couples rock uplift...

Arculus, R.J., 1987. The significance of source versus process in the tectonic controls of magma genesis. In: S.D. Weaver and R.W. Johnson (Editors), Tectonic Controls on Magma Chemistry. J. Volcanol. Geotherm. Res., 32: 1-12. Despite the association of certain characteristic trace-element signatures with particular tectonic environments of eruption, there are accumulating data which would resu...

VistamaxxTM Specialty Elastomers are polyolefin elastomers with isotactic propylene crystallinity. These polymers contain a predominant (>80%) amount of propylene with isotactic propylene crystallinity, with the balance of the composition being ethylene and other αolefins. This new family of thermoplastic elastomers are highly elastic and exhibit excellent recovery from deformation. These polym...

Non-Newtonian Fabrics are produced from Polymerization of Terephthalic Acid and Etylene Glycol. In view of manufacturing defects, the finished products are sold at a massive discount of 45%-65%. Presently manual inspection is being done, where an expert inspector detects only 70% of defects. Here, we are simulating automatic defect detection of fabrics by means of using computers. We proposed t...

This paper presents an extensive transistor sizing analysis for regular transistor fabrics. Several evaluation methods have been exploited, such as DC simulations, ring oscillators and single-gate open chain structures. Different design aspects are addressed taking into account stacked transistors, cells with drive strengths and circuit critical paths. The performance degradation of using regul...
