Functions of the Haversian system.
The Haversian system or osteone has been traditionally adopted as a universal unit of structure in compact bone. The basic functions and the structural significance of primary and secondary Haversian tissue, however, are poorly understood. Two explanations on the functional meaning of the secondary Haversian system have been proposed. These are (a ) the interpretation of the osteone as an exclu...

15 صفحه اولAbsence of Typical Haversian System from the Compact Bone of Some Reptile and Bird Species
Background and Objective: Mammalian compact bone is composed mostly of Haversian system. Although there are many studies describing the typical Haversian system in mammals, there are few studies conducted on bones from non-mammalian species. The objective of the current study was to investigate the existence of the typical Haversian system in compact bones from reptiles and birds. Materials and...
متن کاملThe method of radial basis functions for the solution of nonlinear Fredholm integral equations system.
In this paper, An effective and simple numerical method is proposed for solving systems of integral equations using radial basis functions (RBFs). We present an algorithm based on interpolation by radial basis functions including multiquadratics (MQs), using Legendre-Gauss-Lobatto nodes and weights. Also a theorem is proved for convergence of the algorithm. Some numerical examples are presented...
