An image analysis technique is used to estimate the two-dimensional instantaneous density field of unsteady gravity currents produced by full-depth lock-release of saline water. An experiment reproducing a gravity current was performed in a 3.0 m long, 0.2 ...
We review the recent progress achieved by our international collaboration on novel imaging techniques based on high-brightness and highly coherent synchrotron sources. After outlining the background, we will discuss the technical progress of recent years. ...
Purpose. To assess the effect of external mechanical microstimuli of controlled magnitude on the microarchitecture of the peri-implant bone beds in rat tibiae. Materials and Methods. Tibiae of forty rats were fitted with two transcutaneous titanium cylinde ...
The goal of this study was to investigate if the preparation of implantation site has an impact on bone formation inside tissue engineering scaffolds. For this purpose, two different drilling techniques were used to create a hole in distal femurs of rats b ...
There is increasing evidence that mechanical stimulation affects the fate of tissue engineering scaffolds. In clinical situations, it is critical to accelerate bone formation inside the scaffold to reduce the recovery time and increase the chance of succes ...
The present work forms part of an ongoing effort at the Laboratory of Polymer and Composite Technology (LTC) to develop novel solvent-free processing methods for next generation resorbable porous scaffolds for bone replacement, based on supercritical carbo ...
We review the recent progress achieved by our international collaboration on novel imaging techniques based on high-brightness and highly coherent synchrotron sources. After outlining the background, we will discuss the technical progress of recent years. ...
In this paper we present a novel framework called geodesic active fields for general image registration on Riemannian manifolds. In image registration, one looks for the underlying deformation field that best maps one image onto another. This is a classic ...
After a fracture, fixing a plate to a broken bone can be problematic if the bone suffers of osteoporosis. In order to find a solution to increase bone density around the plate screws, one solution is to insert a drug-delivering bone plug that inhibits bone ...
Background: Local bisphosphonate delivery may be a solution to prevent periprosthetic bone loss and improve orthopedic implants fixation. In load-bearing implants, periprosthetic bone is exposed to high mechanical demands, which in normal conditions induce ...
