What if the journey took weeks under difficult conditions? If you answered Whatever it takes, you echo the feelings of the 12 million immigrants who passed through these now quiet halls from 1892 to 1954. Ellis Island afforded them the opportunity to attain the American dream for themselves and their descendants. Come hear their stories.
Distal hooks at each end of the side struts allow for filter anchoring (Figure 9G). It is composed of nitinol material, making it MRI compatible.This filter has a small and long delivery system (8F), thus, permitting placement via the antecubital approach.
The nitinol wire provides a low constant force at human body temperature used to straighten teeth while reducing the need for wire retightening. The transition temperature of these wires are made so that they generate force at the temperature of the human mouth (about 37C (98.6F)).uperelasticity is a unique property of SMA. If the SMA is deformed at a temperature slightly above its transition temperature, it springs right back into shape. This springy property is called superelasticity.
