An outpatient surgical center can include a hybrid operating room. The hybrid operating room can include at least one radiation shielded wall, a floor, and a ceiling. The hybrid operating room can also include an imaging device disposed in the hybrid operating room. The hybrid operating room can further include an operating table disposed in the hybrid operating room. A building for the outpatient surgical center can initially be constructed to conform to International Building Code (IBC) Class B standards.

Materials, such as biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. Conveying systems, such as flowing gas conveying systems and such as closed-loop flowing gas conveying systems are described.

A radiation-shielded structural enclosure is formed from layers of material having higher and lower Z (atomic) numbers. The enclosure may be formed from layers of titanium that are bonded to opposite sides of a layer of tantalum. A layer of aluminum alloy may be bonded to at least one of the layers of titanium. The enclosure provides structural support for components disposed inside the enclosure and provides radiation shielding for the components.

A radiation shielded vault structure includes a rigid outer structure comprising a plurality of rigid structural components that are interconnected at elongated joints to define an interior space. The structural components include a layer of lower atomic number (Z) material such as aluminum alloy and one or more layers of higher atomic number (Z) material titanium and/or tantalum. The vault structure may include radiation shield members extending along the elongated joints to provide radiation shielding at the elongated joints. The shield members comprise a higher atomic number (Z) material such as titanium or tantalum. The rigid structural components may comprise plate members that are interconnected along side edges thereof. End plates may be attached to the plate members to close off the interior space.
