Oricalco - thermal shape memory fabric
The first orthogonal weaving example of Nitinol. The 'Thermal Shape Memory Alloy' is characterized by its extraordinary ability to recover any shape, pre-programmed, upon heating. Until today this light weight alloy with about 50% Titanium inside has been used in advanced sectors like space and recently in medical applications. Moreover this fabric is the first for which the shape memory alloy, named Nitinol, was weaved orthogonally that is to say that Oricalco is the first fabric with shape mem

Amazon Deforestation Model
This series of animations depicts the results of a computer simulation of the effects of deforestation on the surface temperature and precipitation in the Amazon region. Six animations are shown - a control simulation, a deforestation simulation, and the difference between the two for both surface temperature and rainfall. The period simulated is the second half of 1987.

PediNeuroLogic Exam: Newborn: Normal: Positions - Vertical Suspension
The examiner holds the baby in the upright position with feet off the ground by placing the hands under the arms and around the chest. The baby should be suspended in this position without slipping through the hands of the examiner. If there is shoulder girdle weakness the arms will extend upwards and the examiner will have to reposition their grasp of the baby to avoid the baby slipping through their hands. It feels like trying to hold on to a slippery fish. A neuroscience tutorial focusing on
