By means of experimental investigation, the friction coefficient of SIB is indicated, and according to the test data, estimation formula of friction coefficient is regressed.
In Dolce’s study[3], it is indicated that in the temperature from -10℃ to 20℃, lubricant can reduce the friction coefficient to 1/5, and when the temperature rise up to 50℃, the reduction can be 1/8.

Drip irrigation technology can also increase the land productivity, reduce the usage of chemical fertilizers, and effectively prevent the soil fertility reduction and non-point source pollution caused by loss of nitrogen, phosphorus and other nutrients.
The saved water resources can be used as ecological water, slowing the reduction of arable land caused by desertification and soil erosion and keep more water in aquifers.

All quantities are in good qualitative agreement with the available experimental data.
In order to compensate this reduction, other components of the total entropy (electronic and lattice parts) are increased.
This value of J is equal approximately with experimental exchange constant J ~ 2 meV for Ni-Mn-Ga, which obtained from experimental data of the phonon dispersion curves of the Ni-Mn-Ga [6].
It is shown that the results of the calculations are in good qualitative agreement with available experimental data.

In vitro nitrogen-fixing activity In vitro nitrogen fixation of T21 was measured by acetylene reduction assay as described by Elbeltagy et al. [21].
A phylogenetic analysis was performed using the software package MEGA, version 3.1 [25], after multiple alignment of the data using CLUSTAL_X [26].
In fact, strain T21 showed nitrogen-fixing activity in N-free culture medium, with an acetylene reduction activity of 16.95µmol C2H4 ml-1 measured by acetylene reduction assay method.
Table 1 The physiological characteristics of T21 Characteristics Result Characteristics Result Sugar utilization Gelatin liquefaction - D-glucose + Phenylalanine deaminase - D-fructose + H2S production - Sucrose + V-P test + Mannitolum + Catalase test + Maltose + Urease test - Citrate utilization test + Nitrate reduction + Malonate utilization test - Salt Resistance - Starch hydrolysis - M.R.test + Based on the morphology, cultural characteristics, physiological and biochemical properties, 16S rDNA sequence and phylogenetic tree, strain T21 was identified as Pantoea agglomerans T21.

The top and bottom grains of the pair both enjoy relaxations (i.e. deviations from homogeneous strain which allow a reduction of slip activity) of the type l13 and l23, but in a coupled way: the relaxation of the top grain is opposite to that of the bottom grain.
It is seen that for cold rolling of AA1200 (commercially pure aluminium) the results for FC are not so bad up to 63 % thickness reduction, but for higher reductions, the models that take the stress interactions between neighbouring grains into account (CPFEM, LAMEL, GIA, ALAMEL) clearly lead to the best results.

However, lack in durability data requires more study should be conducted especially focusing on microstructural behavior.
The reduction in band intensity is due to the addition of NaOH as well as the increase in the amount of tetrahedrally-positioned Al atoms in the geopolymer matrix [13, 14].
The wavelength which is shifted to lower wavelength can be explained by the reduction in intensity that will eventually decreases the length of chain of Si-O-T.
Shifted wavelengths to lower wavenumbers can be explained by the reduction in intensity that eventually decreases the length of Si-O-T chain, and thus stops aluminosilicate gel formation.
These causes are accountable for the compressive strength reduction obtained in normal cementitious materials.
