Bordallo was given several cement samples from Brazil – samples which included varying amounts of ash from sugars cane production. She examined the innermost dynamics of the samples at the ISIS facility in britain. She says the samples were put into a device where they were bombarded by neutrons. When it sets up completely, ash concrete is a lot more powerful Using neutron scattering, we are able to observe how the water in the sample moves. Neutrons are shot in to the sample so when neutrons strike the water’s hydrogen atoms, they interact and the neutrons scatter and so are picked up by the detectors, said Johan Jacobsen, who performed the experiments as part of his thesis for the graduate system in physics at the institute.Quigley, MD, Department of Neurosurgery, Allegheny General Medical center, Pittsburgh.

This article and editorial are posted on-line at: CSDH is relatively common, among the elderly especially, with around incidence of 7.4/100,000 in that group. A CSDH is an older clot of bloodstream on the top of brain beneath its external covering. This is even more common in the elderly due to normal brain shrinkage occurring with aging. This shrinkage stretches and weakens the bridging veins, in order that even minor head trauma can cause tearing of blood vessels over the mind surface, producing a slow accumulation of bloodstream over several days to weeks.
