Introduction Diamond sawblades are commonly used in civil engineering industry for the cutting of concrete material replacing the conventional demolishing and rebuilding approaches.
In order to find out the characteristics of concrete sawing and improve the application and manufacturing of diamond saw blade for civil engineering, in this paper the cutting forces of different concrete especially reinforced concrete in dry cutting process were investigated.

Two main types of fractals will be considered including iterative function system (IFS) fractals (e.g., self-intersecting fractal objects, simply connected fractal objects, multiply connected fractal objects, natural objects, area filling fractal objects, etc.) and complex fractals (e.g., quaternion Mandelbrot set, Materials Science Forum Vols. *** 723 quaternion Julia set, filled-in Julia set, contour Julia set, dust Julia set, Dendrite Julia set, etc.)
It is the layer manufacturing (LM) technology, also known Materials Science Forum Vols. *** 725 as solid freeform fabrication (SFF,) computer automated manufacturing or rapid prototyping (RP.)
Unless, the FDM use the water-soluble support material to support the free-formed layers and which Advances in Materials Manufacturing Science and Technology 726 can be dissolved away.

Advances in Materials Manufacturing Science and Technology 274 The main objective of this study was to develop a BCP/PLLA composite material that is not only osteoconductive but also mechanically compliant, and suitable for application as bone implant material.
Advances in Materials Manufacturing Science and Technology 276 After a hot pressing period of 30 minutes, more compact composite has been obtained (with PLLA with Tm = 447.8 K and ∆HTm = 45.3 J/g).
Under the influence of pressure and since the density of polymer significantly decreases with temperature, surfaces of BCP particles Materials Science Forum Vols. *** 277 are uniformly coated with PLLA matrix.

This can also be achieved by inviting people to attend forums and hearings on the subject.
Secondly, we can use the way of forums and hearings.
Learning from western countries like the USA and Canada, we can conclude that the engineer is also the spokesman of the public [7].
A strong coordinating ability in the engineer shall help the developer and company improve their traditional ideology.
Establishing Urban Planning Committee System Referring to the advanced experiences of cities like Shenzhen and Hong Kong, we may set up urban planning committee system to promote scientific and democratic principal.
