Graduates from the Biological Sciences program will have demonstrated: An understanding of the tenets of modern biology and an understanding of how cellular functions are integrated from the molecular level to the cellular level, through to the level of organism, populations and functioning ecosystems.
Toxic hazard studies of flexible polyurethane foam include small scale testing and large. scale testing. The combustion modes examined include thermal decomposition, smoldering, and open flaming, and under ventilated flaming combustion. Of the small-. scale studies, only a few include smoldering foam.
And the fact is, the harm in hitting a shaft that is too flexible is much less than the harm in hitting a shaft that is too stiff. As equipment guru Tom Wishon has said, when unsure about flex, always err on the side of more flex (meaning, a softer shaft). If you can't decide between Regular and Stiff, go with Regular.
