STATIC AND DYNAMIC PROPERTIES OF FIRE - RESISTANT WOODEN STRUCTURAL ELEMENTS October 1966
A series of treated and untreated laminated Douglas fir beams and plywood panels were subjected to static and dynamic loads to study the effects of pressureimpregnation with fire-retardant chemicals on the mechanical properties of wood and to extend the existing knowledge cf the dynamic properties of wood. Results from the beam tests indicate that designs should be based on use under wet condit...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

However, the immediate enthusiasm which greeted their introduction has had to be checked by the realization that many of the important organisms affected readily develop resistance to the antibiotic ...
متن کاملFire resistance of FRP reinforced glulam beams
Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) are increasingly being used to reinforce glue-laminated timber (glulam) beams, creating a new composite glulam (FRP glulam) significantly stronger in bending than a conventional (unreinforced) glulam of equal size. Large timber members have long been recognized for maintaining structural integrity in fires and this p...
