Galene Integration
Galene Structure. At the heart of Galene's integration strategy lies its fusion with a titanium base. This integration ensures stability, providing a robust foundation for the biomimetic cartilage. Galene has a porous titanium base, which gets covered with ingrown bone. Such a structure promotes long-term fixation and contributes to the overall ...
Galena: The mineral galena information and pictures
Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver. Because of this, silver-rich Galena is also an ore of silver. . Another …

Galene Properties
Galene's core strength lies in its biomimetic design, crafted to mimic the properties of native cartilage. A defining feature of Galene is its fusion with a titanium base. This integration serves a dual purpose – providing a stable foundation and enabling porous titanium to facilitate bone ingrowth. The result is a robust structure that ...
Species-specific traits predict genetic structure but not
We investigated the genetic structure of three fruit-feeding, forest butterfly species, Aterica galene, Euphaedra medon, and Gnophodes betsimena, collected from forest fragments in the moist semi-deciduous forest zone. These three species were chosen because (1) they are sufficiently common that they can be collected from most forest …
