Introduction Wood and reinforced wood are currently being developed as possible structural and bearing materials due to their aesthetic value as well as their wear and mechanical properties.
However, the wear rate is significantly smaller for WPC than for the other two materials.
Based on previous reports, there is no research focused on tamarind wood as bearing materials.

However, these networks only solve the problem of interpersonal information exchange, but the material-material communication and material-human communication are still not well resolved.
In this context ubiquitous sensing technology emerges, which is to make our current information network an extensive, efficient, reliable system and to realize the large-scale implementation of material-material communication and materials-people communication[1-4].

Light intensity modulation is achieved by the change in refractive index of the modified cladding material when it is exposed to a chemical vapor.
This color change forms the basis for using PANi film as sensing material for detection of acid/base vapor.

The potential advantage of A/O bioreactor system is that, the anoxic treatment will oxidize organic materials in the waste while reducing the concentration of odorous compounds associated with anaerobic treatment.
Materials and Methods Experimental Set-up This research was carried out in Southeast university campus of Taihu Lake environmental program, in Wuxi, Jiangsu Province.
Both of the reactors column (A/O) was filled with a non-woven fabric filter materials of length 2500mm, width of 50mm, surface area of 150m2/m3 and with porosity of 97%.
Results and Discussion Organic Material Removal (COD) The average removal efficiency of COD was 77.2%.

Introduction With the development of socio-economic and the advancement of science and technology, People put forward higher requirements for the materials,steel is no exception, People are more strict to the requirement of steel quality, To improve the quality of the steel, We must improve the cleanliness of the molten steel, that is, reduce the number and size of inclusions in the molten steel.
Cleanness is one of the key factors when looking at the present and future role of steel as the most important material for mankind. [1]Steel cleanness is control by a wide range of operating practices throughout the steelmaking processes.[2] Non-metallic inclusions have a density lower than that of steel so that these inclusion tend to rise out of the liquid steel to the slag.

Materials and methods Water quality.
Fig.3 The concentrations of COD and oil in the effluent of treatment processes COD and oil of influent were obviously fluctuated, but the effluent of hydrolytic acidification was more stead, The COD removal of influent after hydrolytic acidification process was limitary and the removal rate was 20.4% ~ 40.7% and that of oil was 25.5% ~ 39.8%, which indicates that there are a large number of no biodegradable materials in the wastewater.
Hydrolytic acidification process is an effective pretreatment methods for the industry wastewater, and it could transform the big-molecule organics of oil, saturated hydrocarbon, asphaltene or aromatic hydrocarbons into the biodegradable small-molecule materials and could improve the biodegradability of wastewater, and create beneficial condition for the sequent HCR process.
