Amin et al. [7] analyzed a multistage multiproduct production line with the purpose of evaluating its behaviour regarding different production control strategies.
Al-Tahat et al. [10] studied a multistage multiproduct production line with the aim of developing a model which would allow one to determine, amongst other parameters, the optimal number of kanbans circulating between the work stations.
In Resano et al. [12, 20], the incompatibility between equations (2) and (4) (see section 3) was demonstrated.

Furthermore, an in vivo study by Porter et al. indicated more rapid remodeling of bone surrounding the Si-HA when compared to HA [6].
The ion-substituted hydroxyapatite (Si-CHA) was prepared according to the method described by Ibrahim et al [7].
The obtained mixtures were washed with de-ionized water before immersion in 0.1M aqueous glycine solution 99% (El Nasr Pharmaceutical Chemicals Co.) to block the residual aldehyde groups and get rid of any toxic un-reacted glutaraldehyde.
This view is in accordance with what was previously reported by Kim et al. [3].
The present findings are in accordance with those of Chang et al [13] for gelatin/HA nano-composites.

The multiaxial equations for the two-layer viscoplastic model are defined as follows: Ισ σε )( 1 v v v v el v tr KK     (1) Ισ σε )( 1 p p p p el p tr KK     (2)  vvv εεKσ  : (3)  ppp εεKσ  : (4) vp σσσ  (5)with the yield surface defined by:   0  ασ pf (6) where  0 is the current size of the yield surface and  ασ pf is the equivalent (von Mises) stress with the back stress α defined as:      dev p dev p pf αSαSασ   : 2 3 (7) where dev α is the deviatoric part of the back stress and pS is the deviatoric (plastic) stress tensor.
Thomas et al. [18] showed that for the same strain amplitude, the creep-fatigue damage of Inconel 738 material for temperature cycles of 500 to 850ºC was more severe than for isothermal testing at 850ºC.
Similarly, for the nickel base superalloy MAR-M-200, Bill et al. [19] observed that TMF in phase lives, for temperature variations from 450 to 1000ºC were significantly shorter than their isothermal counterparts.
