In other words, for the time being, full cartilage replacement with synthetic materials yet appears as being the most probable choice for patients enduring chronic joint pain.
It was thus suggested, in agreement with previously given statements [2], that cell-based repairs could not be achieved by simply placing engineered tissue atop of defective tissue.
Materials and Methods Osteoarthritic knee cartilage and control samples.
This phenomenological relationship clearly shows how Raman spectroscopy might play a key-role in the technological feasibility of future diagnosis of early osteoarthritis.

However, the construction of towns and villages energy-saving housing is a complex system engineering, which involves the feasibility of the project, the advancement and economics of energy-saving technology, energy detection, energy management and so on.
The scope of the evaluation including site planning, energy and atmosphere, water saving, materials and resources, the indoor air quality and technology innovation.
This is the first evaluation system about the ecological housing in China, and it is formed by five sub- projects: the planning and design about the residential, energy and environment, the indoor environment quality, the water environmental in residential, materials and resources.
The towns and villages energy-saving housing is a systems engineering with the advanced technology as a necessary condition for building energy-saving design.
At the same time, the technology innovation and promotion level, and the energy-saving materials promotion level in the market play an important role to evaluate whether the energy-saving technology which used is feasible or not in the construction of towns and villages housing.

The key point is to focus on the analysis of planning object’s material property and the sites own conditions.
The famous work, Church on the Water, is a kind of narrative of spirit more than the structure of material space.
Here, it is an extensive and diffusive concept space with a prelude and identity more than a material space meeting the function of entrance.

Since the blade dynamic coefficient Bb is very complicated to solve, engineering practice often uses empirical formulas to calculate.
Fracture Blade Analysis (1) From the chemical composition analysis results of the fractured leaves, it is known that the chemical composition of the blade material meets the technical requirements of GB/T 8732-2014 "Steel for Steel Blades".
In summary, the material of the broken blade is normal, and the cause of blade failure is not caused by abnormal material

E-glass fibers are still the major reinforcing material used in GRPs.
In general, most researchers considered the acid concentration as the only key parameter which affects corrosion behavior of E-glass fiber.
Experimental Procedure The material used was an E-glass fiber roving supplied by Jushi Group Co., Ltd (Zhejiang, China) of chemical composition shown in Table 1.

Introduction Titanium nitride (TiN) thin films deposited by reactive magnetron sputtering is widely used for improving the hardness and wear resistance of materials surfaces [1].
Negative bias voltage of the substrate can be varied in order to change the energy of the bombarding ions which is the key to change the film microstructure.
