background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...

The introduction of carbon-fibre reinforced plastics in load bearing automotive structures provides a great potential to reduce vehicle weight and fuel consumption. To enable the manufacture and assembly of composite structural parts, reliable and cost-effective joining technologies must be developed. This thesis addresses several aspects of joining and load introduction in carbon-fibre reinfor...

This paper describes the results of temperature monitoring a frozen wall (FW) around skip shaft potash mine under construction. The data on measurements in control-thermal boreholes were used to parameterize mathematical model heat transfer, which allowed for reconstruction field throughout entire cooled and soil volume. resulting distribution FW zone greater than 1 year was determine strength ...

Data load balancing is a challenging task in the P2P systems. Distributed hash table (DHT) abstraction, heterogeneous nodes, and non uniform distribution of objects are the reasons to cause load imbalance in structured P2P overlay networks. Previous works solved the load balancing problem by assuming the homogeneous capabilities of nodes, unawareness of the link latency during transferring load...

Recent studies have finally produced accurate measurements of the mechanical properties of carbon nanotubes, confirming the anticipated results computed from quantum and molecular mechanics. Several studies have also predicted an enhancement of these material properties as a result of electron irradiation. Here we prove conclusively through a rigorous TEM imaging study that this enhancement occ...

BACKGROUND The major objective of the present study is to investigate the differences in the load and strain changes in the intertrochanteric region of human cadaveric femora between the loss of medial or lateral wall and after treatment with proximal femoral nail antirotation (PFNA). METHODS After measuring the geometry of the proximal femur region and modeling the medial or lateral wall def...
