Abstract: Employing methodologies and systems to detect damage initiation and growth inside a composite material (matrix cracking, delamination, fiber break, fiber pullout, etc.) wherein damage produces high-frequency acoustic emission (AE) waves that are transported to recording sensors along with relatively lower frequency waves representing the flexural deformation of the impacted composite structure.

Abstract: Injectable iron compositions comprising iron, a carbohydrate, a stabilizing agent and water are provided. These iron compositions can be prepared by mixing iron with a carbohydrate and water to form a mixture and adding a stabilizing agent to the mixture to form the stable injectable iron composition. These compositions can be considered “ready-to-use” and can treat a variety of diseases, disorders, or conditions characterized by iron deficiency or dysfunctional iron metabolism, for example, anemia.

Abstract: The invention provides a scaffold for bone or cartilage replacement, in which the scaffold is fabricated from naturally derived polymers. In one embodiment the invention provides a bone replacement scaffold, wherein the scaffold comprises sintered polysaccharide microspheres. In a particular embodiment the invention provides a bone replacement scaffold, in which the scaffold comprises polysaccharide microspheres comprising ethyl cellulose microspheres and/or cellulose acetate microspheres. The invention further includes methods of making bone replacement scaffolds and methods of treating bone injury in an animal.
