Polyurethane’s modulus gradually increases as the temperature is reduced below -18°C (0°F), which increases its stiffness and impacts other performance properties. In general, brittleness becomes an issue around -62°C (-80°F). Exact values depend on the polyurethane formulation. [pdf]

Ide grew up in , which he used as the setting for a series of crime novels that feature his recurring young protagonist, Isaiah Quintabe. Ide's 2016 debut novel IQ received high critical acclaim and was included on numerous Top 10 book lists for both 2016 and 2017. It went on to be nominated for the 2017 for , and received many other nominations and awards. IQ's sequel Righteous was also wi. [pdf]

The instrumentation of a DMA consists of a such as a , which measures a change in voltage as a result of the instrument probe moving through a magnetic core, a temperature control system or furnace, a drive motor (a for probe loading which provides load for the applied force), a drive shaft support and guidance system to act as a guide for the for. We can use dynamic mechanical analysis to measure the modulus of the material. Instead of continuously moving all the way through the linear elastic region, beyond which Hooke's law breaks down, we carefully keep the sample in the Hookean region for the entire experiment. [pdf]
