We find that the clean surfaces are semiconducting with surface states
in good agreement with experimental data.
Experimentally, Hollering et al. find an even weaker reduction of the intralayer spacing z12 of 16%.
Nevertheless, the surface states and the observed resonances are in good agreement with experimental data.

Data of numbers of methanogens, fungi, ciliate and cellulolytic indicated that they were linearly decreased by addition of FLLE (p<0.05).
Addition of FLLE to diet increased diet nutrients digestibility and slaughtered body weight gain in sheep according to the results of Qiao et al (unpublished data).
Statistical analysis Data of in vitro experiments were analyzed using a completely randomized design.
The data were analyzed by a general linear model procedure of SAS (SAS, 2003).
Therefore, the reduction of ammonia concentration by FLLE supplementation may be due to the inhibition of bacteria and protozoa.

The obtained electrical properties confirmed the suitability of the surface-coating to provide simultaneous oxidation-reduction driven reactions under the photoinduced catalytic activity.
(Pantaroto et al. 2018) examined the antimicrobial effect of titanium discs coated with different types of TiO2 (anatase and rutile) and concluded that when these were subjected to UV-A for one hour, A-TiO2 (anatase) and M-TiO2 (mixture of anatase and rutile) exhibited an antibacterial action by 99.9% and 99% respectively, whereas R-TiO2 (rutile) did not exhibit significant bacterial reduction.
A cubical function curve fit was added to the data, shown as dotted blue and black lines in Figure 5(a), to assist in understanding the general trend of the photoelectric reaction to be essentially different, and it appears to be in favor of the UV illuminated discs (the more negative the current the higher the photogeneration).

A large volume of selected experimental data has been collected from existing literature and then analyzed.
The new empirical model seems to perform much better when applied to the published experimental data on normal weight concrete over a wide strength range.

Recently, micro-computed tomography has made it possible to obtain two-dimensional and three-dimensional data of trabecular microstructure without destruction of bone samples.
The microstructure showed deterioration in the osteoporosis group, as expressed by significant reduction in the bone volume, the bone volume fraction and the trabecular number and an increase in trabecular separation when compared with those of non-osteoporosis group.

The acquired data presents that the roughness exceeds the tolerance during the processing by tool made of H10F alloy later than by tool made of VK6 alloy.
Reduction of hard alloy grain is the main trend in structure changing.

From the data, highest efficiency was obtained from sample deposited at 3500C which is 0.114493% followed by 0.007912%, 0.000374%, 0.000335%, 0.000001%.
The reduction in sp3 ratio reduce the dangling bond [11] and from the electrical and optical properties it was observed that at higher temperature, the sp3 ratio reduce, based on the incresing conductivity and reduction in optical band gap energy.
This gives rigid explaination on the cause of reduction in efficiency as temperature increase.

Historical data provided by tank manufacturers, shows that within the range of dimensions used in this investigation, the failure is dominated by buckling [4].
Results shows that the tank length and the buckling pressure appears to have a close to linear relationship up to a tank length of approximately 3.6m after which slope changes and the rate of reduction in buckling pressure becomes less sensitive to any further increase in length of the tank.
It is shown that the reduction of 83% in rib-spacing lead to 200% increase in buckling pressure, and the highest appears to be at m.
A reduction in the ribbed tank’s diameter from 3.2 to 1m (70%) shows an increase in buckling pressure from 8.5 to 36.2kPa (425%).

This is, however, difficult to achieve in constitutive model using only two scalar damage indicators for tensile and compressive behavior, due to the lack of experimental data.
On the other hand, it is also observed that the material deterioration leads to a decrease in the elementary area of resistance and hence the reduction of the material strength, resulting in the indirect coupling between damage and plasticity.
This implicit coupling characterizes the strength reduction due to the material deterioration and is equivalent to introducing effective instead of nominal stress into the yield function [15].
The coupled damage-plasticity model is intended to capture important features of the material behavior such as the strength reduction, stiffness degradation, and permanent deformation; all of which occurs in both tension and compression.

In accordance with the 2011 data, assuming the limestone are all used for the cement production and are consumed about 20 million tons per year, 20 years later China's cement industry will be difficult to sustain.2)The impact of cement industry on the environmental load, including CO2, dust, SO2 and NOx, industrial waste emissions and noise pollution source load is severe, especially on the dust (soot) pollution, accounting for 40% of the emissions of industrial dust and ranking first in all kinds of industry[2].
Applying wastes as the secondary fuel of cement kiln had several advantages including the emission reduction of CO2, SOx, NOx and methane due to burning coals, less expense of waste disposal, and economic benefits of the cement plants.
After solid-liquid separation, NaOH and NaSH were added into filtrate to adjust pH value and oxidation-reduction potential.
With the purpose to achieve the safe treatment, recycle, reduction socialization and industrialization of urban waste disposal, development of eco-cement become an important part of eco-city construction and strategy of sustainable development.
