The copper alginate fibers as a new type of alginate fiber are made using sodium alginate as raw material, through a series of ion exchange[8].
Materials Two types of bacteria were used in the study, namely Escherichia coli(ATCC 25922) and Staphylococcus aureus(ATCC 25923).

Over the past 20 years, there has been great interest in use of calcium phosphates, a principal inorganic constituent of natural bone, as scaffolding materials for bone tissue engineering [1,2].
Materials and Methods CPG with 0.6 of Ca/P molar ratio was prepared using CaCO3 and H3PO4 as raw materials.

AE (Acoustic Emission, referred to as AE) is a physical phenomenon of a material or structure of a local area or the overall external force or internal stress by plastic deformation or destruction of the occasion, of which the savings internal strain energy in the form of fast transient elastic waves release.
Eng Teik Ng and Gang Qi used wavelet analysis of the acrylic adhesive ceramic material fatigue failure in the acoustic emission signal generated[4].
Experimental conditions and parameters as the specific selection: work-piece material is 45 steel ; blade material is YT15 hard alloy ; Tool Types: end mills; sampling frequency : 2 MHz ; sampling length: 128000，continuous sampling; The above analysis, to make as shown in Table 1.1 experimental program, each of the condition collects 30 sets of data .

Bridges and monitoring, evaluation and maintenance service are important measures to assure the safety of Bridges and promote the development of highway transportation science.
The prototype materials should be adopted to make a model under ideal conditions, but the market restrictions, construction conditions and other factors determined that the trial production or purchase close to prototype material performance of the model is used to make model only in the case of possibility.
So the mechanical properties of the prototype material and model material were analyzed through material testing.

Introduction The study of fluid flows with heat transfer is of tremendous importance in engineering and the physical sciences.
Gul et al. [9] considered the melting of a material and unsteady flow of the melted liquid over a permeable rotating disk under the influence of a uniform transverse magnetic field.
