The experimental program consists in performing the bending test of timber beam type structural elements, considering two types of cross-sections, the first being composed by joining three timber boards of 24x90x1800 mm by aid of screws and the second, with wood/GFRP hybrid cross-section, having the same number of timber boards as specified above joined together by two 3x90x1800 mm GFRP interposed lamellae.
Considering the material results obtained from the four points bending test of composed timber beam, CTB, section it may be stated that it pertains to C22 strength class, according to European standard EN 338, with a characteristic bending strength of 22 MPa and a mean modulus of elasticity parallel to the grain of 10 GPa.

Solutions were obtained for mesh numbers 5000 x 5000, 16250 x 23750, and 27500 x 42500 (number of insert mesh x number of workpiece mesh).
It was seen that the results obtained for 40000 and 70000 mesh numbers were close to each other.

According to the survey, 52 families among the respondents relied on agricultural production for their main source of income before earthquake (including farming and breeding), standing 26% of all; after the earthquake, the number falls to 21, occupying only 10.5 % of the total respondents.
This comparison indicates that, the clearing up and reclamation of land, especially grain ration farmland for locals, needs to be included in the planning of state and township levels, so as to guarantee the livelihood of local farmers. 3.3.2 The unoptimistic employment situation in disaster area A trend of "unemployment, re-employment, and secondary unemployment" has developed in disaster area.
In Deyang City, over 1400 industrial and mining enterprises were severely affected; in Mianyang, the number is as high as 1170.
In the short term, post-disaster reconstruction needs a large number of labor, making the re-employment situation fairly optimistic.

J.Ilic, Chizhen Si, J.L.Yang, and F.John used pre-freezing, they either imposed tensile stress on radial section and compressive stress on the grain direction to resist cell wall deformations or exchanged the drying medium-water with ethanol or methanol to reduce collapse[5-8].
The 40 pieces were divided in two groups containing quarter-sawed and plain-sawed lumber, where the the numbers for the quarter-sawed lumber were A-1, A-2…A-5; B-1, B-2…B-5; C-1, C-2…C-5; D-1, D-2…D-5, and the numbers for the plain-sawed lumber were a-1, a-2…a-5; b-1, b-2…b-5; c-1, c-2…c-5; d-1, d-2…d-5.

Today, soybean proteins are considered the most important source of bioactive peptides and an increasing number of bioactive peptides have been identified in soybean protein hydrolyzates and fermented soybean food.
From Table 1, it can be seen that a great number of peptides were yielded during the fermentation of soybean.

According to a large number of previous experimental data[4-6], it is shown that the decarburization leads to a decrease in the creep properties, the severe carburization leads to the low-temperature embrittlement of materials, and the internal oxidation leads to the surface embrittlement.
A good deal of columnar grains was formed on the surface of the corrosion layer, and the scale was continuous and dense, suggesting that the corrosion resistance is good.
A large number of holes on the surface reduced the protective capability of Inconel 617 scale; 4).

Fig. 2(a) exhibits a SEM panoramic image of the FeS2 products which consisted of a number of microspheres, and the spheres have good uniformity.
The nucleation mechanism of the precursor liquid as a sulfur source is as follows: S2- reacts with S0 forming S-, then Fe2+ reacts with S- to rapidly form a vast of FeS2 crystal nucleuses and quickly generate a large number of jelly-like substances.
