The powder formulation also may include a porogen to control the porosity of the resulting three-dimensional implant device. The devices, which are osseointegrating, may include metal-loaded zeolite so as to elute antimicrobial metal ions in a therapeutically effective amount when implanted into a body and exposed to bodily fluid.

Abstract: In an example embodiment, a first set of results from first search results are displayed in a user interface. A plurality of facets, including selectable filters, of the first search results are displayed. A sampling scheme is retrieved, with the sampling scheme defining a first sampling rate for a first number of search results and a second sampling rate for a second number of search results. The first search results are traversed using the sampling scheme, sampling search results for the first number of search results at the first sampling rate and sampling search results for the second number of search results at the second sampling rate, for each sampled search result, causing an increase in a facet count for a facet and/or selectable filter having a matching value in the sampled search result. Facet counts for each of the facets and/or selectable filters are displayed in the user interface.

Abstract: A location query engine in a social networking system provides users with a subset of candidate locations based on location query received from a user. The social networking system identifies candidate locations from stored location data that has one or more attributes matching at least one attribute of the location query.

Abstract: Electrical power is provided to power consuming, heat-exhausting devices by multiple gas-fueled electrical power sources located near such devices. Exhaust heat from such devices is utilized as intake cooling air for the gas-fueled power sources, thereby excluding them from cooling capacity requirements. The gas piping delivering gas to gas-fueled power sources is positioned so as to be within hot aisles comprising exhaust heat. The gas piping is located up high for lighter than air gasses and near the floor for heavier than air gasses, with leak detection located nearby. Additionally, gas piping is externally coated with material that visually indicates a leak. By locating gas piping in the hot aisle, exhausted heat increases temperature and, thereby, pressure of the gas, resulting in more efficient gas distribution through the piping and preventing valve freezing. Furthermore, the gas piping is located after potential ignition sources in the airstream.
