Anaerobic degradation of particulate materials and macromolecules is considered to follow a sequence of four steps: hydrolysis, acidogenesis, acetogenesis, and methanogenesis.
Recent studies have focused on destruction of floc structures and lysis of microbial cells to release biodegradable organic materials and render them more accessible to anaerobic digestion.
Materials and methods TWAS and seed sludge Raw TWAS was obtained from a WWTP in S city, Japan, and was stored at 4℃ in a feed tank.
It was also possible that MW irradiation creates a higher amount of intermediate molecular size organic materials (such as, colloids) between soluble (＜0.45 μm) and particulate (＞0.45 μm)[15].
The authors would like to thank the friends for their continual assistance in preparing and caring out this research in department of civil and environmental engineering, Tohoku University.

In order to achieve the fabrication of highly integrated devices, a bottom-up fabrication method, that is able to launch multiple components made of a various materials into the systems, is required.
One of the key-technologies to achieve the parallel batch process to appropriately address components is self-assembly.
A dsDNA separates into ssDNAs at elevated temperature called melting temperature (Tm), which can be engineered by its length and configuration of the base sequence.

A numerical model of the roof structure was developed in the finite element analysis (FEA) software SCIA Engineer [4].
Considering the stresses in the roof members and structural parameters being analysed, the isotropic material model with mechanical properties of C24 according to [5] is adopted, which corresponds to the applied type of wood (larch).
Conclusions It can be concluded that the stresses obtained by numerical analysis do not exceed the design strengths of material, defined in standard [9].

The key concluding remarks are as follows.

And in the researches lasting for over two decades, the focused material for IBAD was changed from Yttria-Stabilized Zirconia (YSZ), Gd2Zr2O7 (GZO) to MgO.
Its superconducting material was YBa2Cu3O7−x (YBCO, Tc was about 92 K). 2G wires were manufactured by depositing multi-layers on the metallic substrates.
In order to shorten this time cost, other materials for IBAD buffer layers were studied worldwide.

Many experts and scholars had done a lot of work to wind power impact on vegetation and birds security[1-6]. digging and backfill engineering during construction, such as road construction, land leveling, fan base construction, box-type variable project, cable trench engineering, etc., will damage the surface morphology and the soil structure, then cause the surface exposed, damage vegetation and soil fertility, and cause soil erosion[1,7].
Materials and Methods A.
We can dig soil profile to 50cm in deep soil area, and dig to parent material layer if the shallow soil area is less than 50cm.
Meanwhile, site formation, road construction, in cable trench, digging and backfill engineering construction have destroyed the original natural state structure of soil and vegetation during the wind tower location, construction period and operation period, which make the upper and lower soil mixing, soil loose, the gap between the soil become unsteady.
