In this system, diversity is generated by bringing in external material— criolla seed from neighboring states or from other towns.
For example, floods and avalanches invade the interior of buildings with external material; earthquakes, by themselves, according to the referenced authors, do not.
The diamagnetic materials are weakly repelled by an external magnetic field, resulting in a negative reading.
This fastener concept is based on the mechanical properties of elastomer materials and is triggered by an external force applied on the product housing.
On the ground, the antenna is packed by an external mechanical load above the glass transition temperature of SMP material.
The deformation and fracture behaviors of magnetoelectric materials under mechanical loading are affected considerably by an external electric or magnetic field.
Conventional lasers use a pair of mirrors to bounce a light wave back and forth through a cavity containing a material or gas whose atoms are "pumped" into a higher energy state by an external light source.
