Bressiani:Journal of Luminescence Vol. 180 (2016), p. 177. ], Bow et al [2] have developed a route for synthesizing nano-sized β-TCP at room temperature, in methanol solvent, wherein an intermediate amorphous calcium phosphate, CaHPO4 phase, is formed and the incorporation of carbonate during the synthesis process favors a β-TCP phase after 8h of aging stage.
Kumta: Materials Science and Engineering C Vol. 29 (2009), p. 69. ] β-TCP using 50% magnesium (β-TCMP) substituted brushite as a precursor in a method of several digestion/boiling steps.
Materials and Methods The Mg:β-TCP powders were synthesized by co-precipitation method, wherein the phosphoric acid (H3PO4, Synth – Brazil) diluted in deionized water (0.3 M) was slowly added drop by drop (8 mL/min rate) into a suspension of calcium hydroxide (Ca(OH)2, Synth- Brazil) and magnesium hydroxide (Mg(OH)2, Synth Brazil) (0.5 M).

Management information system is a new interdisciplinary subject dealing with computer technology, data communication technology and management science.
By the study on teaching programs and materials and the design of teaching methods and operation courses, cooperative preparation of lessons provides a channel for teachers to exchange information, broaden views and promote the professional competence.
Thus, while analyzing the interpersonal interaction in the teaching, we should turn our focus on the learning process and take the individual knowledge interaction into consideration.[6] The plan of the technical support for the interactive teaching of management information system course under the multimedia environment To promote the efficiency of interactive teaching and get better teaching effects, the technical support for the management information system under the multimedia environment are mainly IT technology, teaching materials, students and teachers.

Compare with experimental method, to obtain the key parts of the structure by employed finite element simulation method is more efficient and practical In other words this method not only save labor and material resources, but also did not interrupt the regular production.

In the analysis conducted by the finite element method, we took the same thermo-physical and thermo-mechanical properties of the base and filler materials.
It is also taken in the analysis that the material behaves elastically-plastically,i.e. ideal, von Misses model hardening materials.
