As the main raw material, cured tobacco cannot directly supply to the cigarette factory and need to redry, namely, a second adjustment of flue-cured tobacco moisture at the basis of cured tobacco to make it real raw materials of cigarette production.
Acknowledgments The research work was supported by science and technology project in Guizhou branch of China National Tobacco Corporation (201020).

Carbon fiber material is widely used in old bridge reinforcement[1] because of its high strength, corrosion resistance, fatigue resistance, construction convenient and well-adapted.
The design steps of paste carbon fiber polymer method for reinforcing bending member : (1) According to the stress , common fault, size, reinforcement and site conditions of the original structure, combined with the designer’s personnel engineering experience, preliminary estimate the quantity of the paste carbon fiber; (2) Calculate the first stage, namely the section stress strength calculation before reinforcement, according to the material mechanics theory of elasticity member under the action of gravity; (3) Calculate the second stage, namely the section stress strength calculation after reinforcement, according to the conversion section principle component under the live load and the later dead load; (4) Check the section stress strength of two stage.
If not, adjust the quantity of carbon fiber until all the strength of every material and the section bearing capacity meet the requirements [4-6].

Statistical/ Empirical-based Vulnerability Assessment The main methodologies used in practice, based on statistical/empirical approaches are [2- 5]: · Screening and vulnerability index methods: They consist in gathering quantitative information on a building or stock of buildings, by using vulnerability-assessment forms including predetermined set of parameters, such as quality of materials.
The unmeasurable factors are the type of the nonlinear behavior (geometric or material) and the severity of the nonlinear behavior.

A lot of research results have been acquired in structure, materials, lubrication and wear model of low viscosity lubricating bearing.
For water lubrication tilting pad journal bearings of nuclear main pump, a fluid-solid-thermal coupling model including the general Reynolds equations, energy equations, heat conduction equations, thermo-elastic deformation equations and temperature and viscosity equations was built [6,7], the model takes the turbulence effect into account.
Damping of rubber is related with material, structure, temperature, stress amplitude, frequency and other factors which can be obtained by testing.

The corresponding results for the high oxygen (HO) material #1 are given in Fig. 3.
In case of #1, the dominant peak in the HO starting material corresponds to the OTD double donor level.

Introduction Eco-mortar is an innovative solution for sustainable construction, using eco-friendly materials like recycled and natural ingredients.
This work deals with an experimental study, whose purpose is to substitute a quantity of cement by other quantities of natural pozzolanic materials.
As pinpointed, the pozzolanic materials are widely used as substitutes in the cement industries [3,4].
Algeria has a significant amount of pozzolanic materials of volcanic origin whose use remains at the level of a few cement plants only.
