The mammalian skeleton undergoes continuous turnover, where overall bone gain or loss is determined by the difference between bone resorption and formation.
The skeleton needs continuous physical stimulation to maintain healthy bones, otherwise bone loss ensues [ 1].
Although some fast-swimming pelagic predators are also elongate (e.g., billfish), morphological specializations of the axial skeleton for continuous swimming have the potential to act as confounding factors when making hypotheses regarding the evolution of vertebral numbers.
This external skeleton underlies a continuous, superficial layer of tissue.
This paper studies the influence on SCC mechanical properties based on the consideration of two types of granular skeleton, discontinuous and continuous, for different strength levels (35 and 60 MPa).
Using the ridges and skeletons of the continuous wavelet transform, we identify weak nonlinearities on damping and stiffness and estimate their physical parameters.
For the both strength levels studied, the mix with continuous granular skeleton exhibited slightly higher segregation resistance and mechanical properties than did mixes with discontinuous granular skeleton.
In sea urchins a spherical, rigid body is formed by the five arms coming together dorsally around the anus; the ambulacral ossicles are immobile, and the body wall between the ambulacra is made rigid by a layer of calcareous plates below the ectoderm, which completes the continuous spherical skeleton.
The volume fraction and the location of liquid phase in the semi-solid state were determined in particular, and the continuous solid skeleton was investigated.
The GF grains in the composites were highly oriented with the Lotgering factor >98%, and a 3D continuous ceramic skeleton was formed when the AlN content increased to 20 wt%.
The human skeleton is subjected to continuous remodeling during its lifespan.
