The status of transparent SiC for short wave (3–5 μm) windows and domes is reviewed. Transparent β-SiC was fabricated by the pyrolysis of methyltrichlorosilane in the presence of excess H2 and argon in a hot wall, chemical vapor deposition reactor. Characterization of the material indicates that the transparent SiC is a theoretically dense, void free, highly pure (99.9996%) cubic material posse...

Introduction: The 35,000 km 2 Marius Hills (MH) complex located in Oceanus Procellarum is one of the highest concentrations of volcanic features (domes and cones) on the surface of the Moon [1]. Domes are 200-500m in height and have a different morphology from the surrounding mare units [2]. The domes are found within all the different lava flows as previously mapped from spectral [3,4] and/or ...

Economy and safety are two important components in structural design process and stablishing a balance between them indeed results in improved structural performance specially in large-scale structures including space lattice domes. Topology optimization of geometrically nonlinear single-layer lamella, network, and geodesic lattice domes is implemented using enhanced colliding-bodies optimizati...

Salt domes, an important geological structure, are closely related to the formation of petroleum reservoirs. In many cases, no explicit strong reflector exists between a salt dome and neighboring geological structures. Therefore, interpreters commonly delineate the boundaries of salt domes by observing a change in texture content. To stimulate the visual interpretation process, we propose a nov...

We have developed a model system for studying differentiation in the mammary gland, by using two clonal cultures deriving from a rat breast adenocarcinoma. They differ in the ability to form domes, structures the significance of which is unknown. By using the subtractive cDNA library approach, we isolated a cDNA that is highly expressed in the dome-forming cells, and identical to the rat8 gene ...

The author describes the use of implants with exteriorized injection domes for patients undergoing breast augmentation. Domes were exteriorized for 1 to 5 days to allow the implant volume to be altered in the early postoperative period. Thirty-three patients were treated without any infections.

[1] A new finite element code for compressible thermochemical convection is developed to study the stability of a chemical layer at the base of the mantle. Using composition-dependent compressibility and a density difference between compositions at a reference pressure, a composition-dependent density profile is derived. Together with depth-dependent thermal expansion, this combination of param...
