Keywords: Artificial bone grafts, mechanical properties, bone cements, injectable materials for bone regeneration Abstract.
Methods and Materials β-TCP was synthesised by heating a mixture of CaCO3 (Merck) and CaHPO4 (Mallinckrodt Baker) with an overall calcium to phosphate ratio (Ca:P) of 1.5 to 1050 °C for 24 h, prior to quenching at room temperature in a dessicator.
Results Compaction of the cement mixes did result in an increase in the wet strength of the set material.

Conjoint analysis was used to analyze how the attributes such as the brand, the price, the raw materials, the environmental certification and the fluorescent additives of the rolling paper affect its purchase on the basis of the data from a survey among the consumers in Changsha.
It was based on those attributes influence most to consumer preferences.On the basis of survey from consumers, analyzed on literature concerning rolling paper,and consulted from papermaking enterprises on information of paper attributes,the attributes of brand, price, raw materials, environmental certification and fluorescent additives were selected for investigation.
After all kinds of papermaking raw material were in detail, many consumers had changed their view of regenerate pulp, as the data showed that the part-worth of regenerate pulp was 0.177, more higher than other two materials.

In recent studies, linear viscoelastic material laws combined with large-deformation theory were used to model brain tissues [17, 51, 52], except for the work of Mendis [53], who employed nonlinear viscoelastic materials under large-deformation.
A hyperelastic material was used for the brain to maintain these properties, in conjunction with a viscoelastic material property, giving the material a decay factor of β = 145s-1.

The optimal process conditions are determined from the test, which will support the production in terms of theory and data. 1 Experimental Materials and Method 1.1 Experimental materials 1) The lean Cd solution, used as subject, is at pH 4.0~4.5, containing Zn 128.1g/L, Mg 20.54g/L, Na 2.66g/L, F 120mg/L. 2) Saturated NaF solution 46.8 g/L at 60 ℃; 10 g/L NaOH solution; H2SO4 solution. 1.2 Experimental Method With the single-factor test method, the NaF-based Mg removal test is conducted to investigate impact of NaF dose (prepared into appropriate saturated solution before being added into the lean solution), pH(conditioned with NaOH and H2SO4), the reactive duration, and the reactive temperature on NaF-based Mg removal.
