Feed Consumption and Cost of Feeding of Bronze Turkey Breeding Stock

open access: yesPoultry Science, 1936
Abstract THERE appear to be available only a few experimental data relating to feed consumption and the cost of feeding adult turkeys; and these data, for the most part, are based on small numbers of birds. Albright and Thompson (1932) state that 26 breeding turkeys (24 hens and two toms) consumed an average of 6.87 pounds of mash, 7.18 pounds of ...

Material Before Morphology: Substrate‐Dependent Mechanical Tuning of Radular Teeth

open access: yesAdvanced Materials Interfaces, EarlyView.
Substrate‐dependent material tuning in Clausilia radular teeth. Closely related taxa retain a conserved gross tooth morphology, but differ in elemental composition and mechanical properties according to feeding substrate. Rock‐associated taxa show increased Ca–Si enrichment and higher stiffness and hardness, especially in the central radular region ...

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.
