The collagen sponge facilitated cell seeding and chondrogenic differentiation of MSCs, and will be useful for cartilage tissue engineering.
The sponge was used for three-dimensional culture of human MSCs for cartilage tissue engineering.
Materials and Methods Preparation of Collagen Sponge.

Fracture strength is one of the key mechanics performances for engineering ceramics products, greatly influenced by the microscopic topography and residual stress field of ground surface.
Up to now, grinding with diamond wheel is the normal technique for machining high hard-brittle ceramics materials [2].
However, since the hard-brittle characteristic of engineering ceramics, the polishing efficiency for ceramics was lower than many other materials.

As the engineering construction project is very complex ,advanced tools are required to assist finishing a project.
Virtual architectural model contains a large number of construction materials and building components and other aspects of information.
Current assets investment refers to occupied total working capital for the maintenance of the project's production and business operation included and are used to the purchase of raw materials, semi-finished products, fuel and power and so on.
The engineering project investment cost control module based on BIM, mainly with the help of component information in the BIM database, through computer automatically identifies components in the model, real-time statistics of the components within the model, uses model to replace the drawings, name, number and size of the materials needed can be generated directly in the model and consistent with the design.

A Fuzzy Set AHP-based DFM Tool Under Concurrent Engineering Environment H.G.
The integration of design and manufacturing activities into one common engineering effort has been recognized as a key strategy for survival and growth.
In this paper, part manufacturability under Concurrent Engineering (CE) environment was analyzed in detail.
Introduction Design for manufacture (DFM) is the core idea and implement way of concurrent engineering, means considering the correlative factors at the same time of designing product.

Profile of Mining Engineering of Wuhan Institute of Technology The mining engineering specialty in Wuhan Institute of Technology is a professional disciplline in training chemical mining talent.
Experimental Teaching Platform Construction Besides of purchasing some basic mining models, the mining staff room wants to order a medium-sized filling system and a series of filling material test equipments to support the mining engineering experimental teaching construction and improve mining engineering scientific research hardware facilities.
The demonstration center, mainly based on the abundant practical teaching resource in the Daye iron ore and assisted by the relevant rich practice teaching resources around the iron ore areas, can meet the mining engineering, dressing engineering, safety engineering, civil engineering, and other professional subjects various practice teaching needs.
The practice teaching project in demonstration centre are background of the practical engineering of engineering unit, which complete with engineering practice.
The mining engineering of Wuhan University of Technology is mainly aimed at building materials mine; Wuhan University of Science and Technology formerly is a distinct characteristic of metallurgical industry university, and its mining engineering training target and students employment to more for metal deposits, as a representative of the solid mineral mining areas.

The collaborative design and manufacturing process reflects the concept of concurrent engineering.
However, the data sharing is passive, which is realized by the way of sending and receiving, so the concurrent engineering is limited.
The system supports the engineering change management which could record the change process and previous version of drawing.
As the suppliers could share the data through the collaborative platform, C919 could be built in the concept of concurrent engineering.
We build the collaborative design and manufacturing system and propose the way to share the data and realize the concurrent engineering.

So, the application in the martial engineering field such as aeronautics and astronautics is becoming increasingly widespread.
