It was previously found that the lateral spacing of the collagen molecules in wet mineralized tissues is exactly proportional to the inverse wet density. Several properties were investigated and the same type of relationship was observed each time. A

Equatorial (d) and meridional (D) spacings of native rat tail tendon (RTT) and unmineralized native turkey leg tendon (UTLT) were measured at ambient and liquid-nitrogen temperatures, using X-ray diffraction. Cooling of air-dried RTT or UTLT caused l

Relationships between the fluoride dosage administered to weanling New Zealand white male rabbits and some mechanical properties of the compact bone were investigated for a wide range of dosages. The measured quantities were density, longitudinal son

Ultrasonic studies on bone have not been done as intensively as other tissues, probably because there is less opportunity to examine bone in vivo by this modality. There is considerable interest in using ultrasonics to learn about the material proper

It was previously shown that the sonic echo wave pattern from a thin layer embedded between two thick layers can be readily and accurately calculated using a recursive expression (1). Two three-layered experimental structures were described where the

The otic bones in this report are the tympanic bulla, the periotic, and the three ossicles (malleus, incus, and stapes) of an adult fin whale (Balaenoptera physalus). The purpose was to determine if the periotic was denser than the other otic bones.

Ultrasonic scanning systems are now available which can be gated at several points in the A-scan, thereby locking on several echoes in the pulse train. Consider the situation of a flat plate where the gates are locked on the echoes from the front and

Summary X-ray diffraction patterns were recorded from fully mineralized and demineralized sections of the cortical bone from cow tibia. The results were used to obtain a measure, d, of the mean side-to-side spacing (equatorial diffraction spacing) of

Several macroscopic physical properties of mineralized turkey leg tendon were measured including wet density, composition, volume fractions of the major components, sonic velocity in three axes, longitudinal modulus and dimensional changes on drying.
