There were the fence posts shaped like upside-down L's, the ink-black barbed wire, the inch-long barbs shaped like bayonets.
The fence posts shaped like upside-down L's weren't factory stock that had been produced elsewhere but plain logs, peeled and smoothed, with narrow boards atop them to complete the L.
Ceremonial houses were built with posts shaped like human figures, and forked posts carved with human heads stood in front of the houses to receive the corpses of war victims.
The novelty of the proposed design is based on creating new post shape that should address the challenges posed using the conventional circular post arrays.
The results show that airfoil post shape has the potential to overcome complications when working with soft biological samples, namely the cells that are not rigid and not spherical.
As regard to post shape, parallel-sided posts provide better retention and less stress formation and increased fracture resistance than do tapered posts [ 2, 5, 18, 28, 37, 38, 42, 46].
Airfoil and diamond post shapes have been proposed and compared against the circular posts.
Comparisons were also made between specimens pre-shape set and post-shape set with and without external constraints.
Moreover, the accuracy of the proposed method is validated by comparing the simulated post-assembly shape with the actual post-assembly shape measured after physically assembling the component.
This time, he would also post digital shape files online: anyone could replicate naledi on a 3-D printer.
