Interventional closure of intracardiac wall defects using occluder devices has evolved as a highly attractive treatment option. However, incomplete and delayed healing reactions often result in a major risk of residual defects, thromboembolism, or device f ...
Tissue engineering scaffolds are porous structures that allow bone cells to reside and produce bone. This process involves migration and differentiation of mesenchymal stromal cells and production of cartilage and bone by chondrocytes and osteoblasts, whic ...
Method and apparatus for estimating a fluid driven fracture volume during hydraulic fracturing treatment of a ground formation. A series of tiltmeters are positioned at spaced apart tiltmeter stations at which tilt changes due to the hydraulic fracturing t ...

Background: The primary stability of cancellous screw is difficult to obtain in bone of compromised quality and failure of screw fixation is common. To overcome this problem, it is proposed to locally deliver bisphosphonate from the screw An in vivo valida ...
Occurrences of large earthquakes having a magnitude larger than eight along subduction zones have been reported worldwide. Due to large number of load reversals the effect of cumulative damage on structural components due to deterioration becomes critical ...
Reversed shoulder prostheses are used for the treatment for glenohumeral arthritis associated to rotator cuff muscle deficiency. The glenoid component is fixed with peripheral screws, which provide the primary stability that is crucial for the long-term os ...
Hygro-thermal ageing of composite materials introduces a modification in the material properties of its constituents and the development of stresses that can lead to severe local damage like fracture of the reinforcing fibers and de-bonding of the latter f ...

In clinical situations, bone defects are often located at load bearing sites. Tissue engineering scaffolds are future bone substitutes and hence they will be subjected to mechanical stimulation. The goal of this study was to test if cyclic loading can be u ...
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 ...
Anti-shielding of a crack tip by a dislocation is examined at the atomistic level for a simple geometry to test classical singular-crack and recent cohesive-crack models of crack/dislocation interactions. The atomistic model shows that, as an anti-shieldin ...
