From a number of popular science textbooks, we can learn about following things.
Through a lager number of cultivation and introduction tests by plant scientists, bright sand stars also include Euphorbia antisyphilitica, Eucalypius, Bursera, Parthenium argentatum and so on.
Compared with the first generation of biomass fuels which takes corns and beans as raw materials, the second generation of biomass fuels, taking algae, straw and other plant fiber as raw materials, enjoy tremendous advantages of not fighting with men for grains, rapid growth and high yields.

A large number of factories, facilities, buildings and streets built in industrial era have become a part of the urban landscape with time flies.
Obviously, a large number of workers lost their jobs.
The visitors can experience the living situation of industry workers by enjoying the scenery of different historic periods, and they can also see the original appearance of some historic buildings such as grain supply centre, post office, and bank.

A great number of disordered particles with the average size of 11– 30 nm are also identified.
We also found two adjacent grains with the orientation angle of 44.2o in Fig. 4(b), indicating that the nanotubes are polycrystal structure.
The nanotubes are made up of a great number of loose particles with the diameter of 4 – 7 nm.

Also, the Al matrix (grey area) presents fine brighter lines which can be due to Al-Si deposition on the grains boundaries due to the melting of the substrate surface, however, the exact phase might be not detected by the XRD investigation due to its fine size of <1 µm.
The mean micro-hardness number of the aluminium substrate (A6082-T6) is 66 Hv0.05.
This enhancement in the hardness number of the multi-ceramic coating is attributed to the contribution of the reinforcements to the Al matrix [40].

These fillers with pozzolanic properties offer nominal advantages and a large number of cement substitutes [12-18].
A total of 273 numbers of concrete specimens (cubes, cylinders, and prisms) was used.
On the other hand, it may be due to pore and grain size improvement procedures that build up the mechanical interlocking in the transition zone.

Mechanical properties of the carburized layer depend on the number of interrelated factors and include the effect of process parameters, base material and surface characteristics.
The steel bars were normalized at 900 ºC for 4 hours, which reduced the grain size from 6.5 to 8 (ASTM E112) and reduced the banded anisotropy as seen in Fig.2.
Opposed to these results, a number of studies [14,22,23] observed significant change in β due to the effect of temperature.

Concrete: 425 Portland cement; lime gravel; medium-grained sand.
Periphery is steel and the material number is 1.
Inner material is concrete (simulated by self-defining material "Cast iron") numbered 2.

Possible applications span from apparently homogeneous materials like metals, whose microscopic grain structure is examined, to obviously hierarchically organized fiberreinforced polymers, on to porous materials, bio materials, etc.
The inclusions approximate glass fibers with a Young's modulus of 75 GPa, a poisson number of 0.2 and a fiber volume concentration of 49.8 %.
The matrix between the inclusions has elastic properties similar to epoxy resin with a Youngs's Modulus of 2.5 GPa and a poisson number of 0.4.

Swamp rice is more common and is mainly cultivated in Artibonite valley, where 80% of national rice is produced (Fig. 3). 28,000 hectares are cultivated in the valley, of which 24,000 are rice fields – a number that could increase, because 32,000 hectares are irrigable land.
The process of separation of grains from stalks is made by hand and leaves on the ground huge amounts of straw which are burned directly on the field.
Constructing rice straw-bale buildings in Haiti would be very complicated for a number of reasons: for instance, it would be hard to get materials, because even if all of them are available there, it is essential to have the right contacts to find the best suppliers and workers.

However, there is every reason to assert that the selective properties of coals with respect to a large number of various substances, including simple and complex ions of gold, silver and some other elements, are determined not only by the porous structure, but also significantly depend on the molecular structure of coals and their electrophysical properties.
Further, grain-size distribution, specific surface of the material under grinding, X-ray phase analysis.
The four-hour duration of the experiment was chosen by us on the basis of literature [18] and own data on the study of the kinetics of sorption of a number of acids by active carbon [19].
