BET surface area and pore volume of monolith silica was at 588.0148 m2/g and 0.895424 cm3/g respectively compared to both hybrid silica which shows a significant reduction at which surface area and pore volume was in the range of 25 - 120 m2/g and 0.04 - 0.2 cm3/g respectively.
This behavior was interpreted taking into account the surface organic coverage of the pores that results in a partial reduction in the pore free volume and according to the literature, the pore blocking effect occurs preferentially in the larger pores [14,15], as observed in the present work.

The reduction of total surface area was directly affect the pore volume of the samples which shows similar trend as decreasing in total surface area contributes to decreasing in pore volume.

The maximum level of LCE and LCC reduction through improving building envelop was also investigated.
Data utilized for computing building materials mass was obtained from the bill of quantities (BOQ) which provides the set of building information including its type, size, quantity as well as price.
Energy reduction for different building envelop compared to base case Table 4.
The best choice of each options, therefore, was integrated to re-investigate the maximum level of LCE and LCC reduction through improving building envelop materials.
However, a number of emission reduction was only 4% compared to the base case.

The climatic data (period of 1989-2015) show that the average monthly temperature varies between 11.39°C (in January) and 32.78°C (in July).
It can be observed that the reduction of Ntot content is important in all filtered water samples.
The percentage of TSS reduction reaches 94.76% and 96.28% using the vegetated filter and unplanted control, respectively.
Results show that the maximum percent of TP reduction reaches 98.65 % (in February) and 95.50 % (in April) using Juncus maritimus filter and unplanted control, respectively.

The fracture strain was increased significantly with the increase of solution time, indicating that the ductility of the composites was greatly increased due to the reduction of brittle β phase and coarse eutectic τ phase.
Meanwhile, the reduction of the β phase resulted in a decrease in hardness after solution treatment.
Fig. 6 (a, b) Polarization curves of the composites in different processing status in 3 wt.% KCl solution, (c) electrochemical data obtained from the polarization curves Summary In summary, the effects of solution and aging treatment on the microstructure, mechanical properties and degradation behavior of the HGM/MA composites were evaluated.
The increase in the UCS was attributed to the solution strengthening of Al and Zn elements, while that in ductility was attributed to the reduction of the reticular β phase and coarse τ phase.
The decrease in the hardness and degradation rate was attributed to the reduction of the β phase.

The reduction in casting variations allows a reduction in machining allowances, which will lower the down stream cost.
The addition of 3 % Mg to Al melt reduces its surface tension to (0.62 Nm-1) at 720 ⁰C, the reduction is about 30 % from its original value [14].
Coating by metallic powder can be achieved by: spray drying, chemical processes (hydrochemical reduction), sol /gel processes etc.

In the controlled rolling process, two stages of rolling (rough rolling and finish rolling) are usually adopted, and large reduction ratio of thickness during this process is essential for pipeline steel [5].
Fig. 3 shows the experimental data obtained via EBSD.
It is well-known that the AF generally nucleated intra-granularly on the crystal defects, i.e. dislocation, deformation band, and large enough reduction ratio, high cooling rate, and low cooling-interrupt temperature are essential for AF transformation [13, 14].
Based on the TMCP stated above, large reduction ratio (52%) during finish rolling and high cooling rate (35℃/s) obtained through UFC were adopted, which increased the nucleation sites and improved super-cooling degree of AF transformation.
Hence, the certain volume fraction of AF for 350℃-processed pipeline steel was attributed to the large reduction ratio and high cooling rate after rolling.

Data indicates about the essential affect of large diameter pipe steel quality and properties on quantity and length of their damages.
Controlled rolling is the most economical method of steel sheet for gas pipe mains and ensures the required level of properties by microstructure size reduction without additional heat treatment.
At present time the high quality pipe steel sheet can be obtained by thermomechanical rolling which provides control of heating temperature, temperature and reduction at rolling, and cooling after rolling.
One of the main tasks of hot rolling process is to ensure the stable course both of the rolling technology and sheet coiling at the rolling mill in the required temperature and reduction regimes and to obtain the desired quality of rolled sheet.
The input variables are mechanical properties and parameters of the microstructure, which, depending on control variables (reduction in rough and finish group of stands, temperature of rolling and cooling), will vary after hot rolling and can be expressed through the values of output variables.

Statistical analyses The data were analyzed by One Way-ANOVA and LSD post hoc testsby SPSS 15.0 for windows and P value less than 0.05 was considered as significant.
PTX led to a significant reduction in VEGF production.
Our data revealed that local administration of PTX has no effect on calcium deposit; however, it can improve organic matrix formation and protein production.
The data showed that PTX caused the osteoblasts to produce protein on the first day, and as the time progressed, the protein synthesis gradually decreased till it reached the level synthesized by the cells on PTX-free condition on day 7.
Our data indicated that local administration of PTX attenuated the VEGF production in MG63 cell line.
