This section, based on the wind tunnel experiment, analyzes the mean pressure data of each point and adopts area weighted average method to obtain shape coefficients on each surface with various wind directions, as well as makes a comparison between the data provided by current codes.
It shows that in 45o wind direction , there is a small peak of base moment coefficient in along wind and across wind directions when the reduction frequency is around 0.1, but the base torsion coefficient is relatively large in the high band; in 135o wind direction, the base moment coefficient in across wind direction has an conspicuous peak when the deduction frequency is around 0.1, and the peak of base torsion coefficient is relatively small; in the two wind directions, the base moment coefficient in along wind direction has no peak frequency, and its shape is similar to the spectrum described by Davenport.
It can be seen that in 45o wind direction, the base moment coefficient has no obvious peak frequency in along wind, across wind or torsion direction, and the base torsion is relatively large in high band; in 135o wind direction, there is a peak frequency of base moment coefficient of structure A in along wind direction when the reduction frequency is around 0.1; in 45o wind direction, the peak deduction frequency of base moment coefficient is less than 0.1 for structure B in along wind and torsion directions; in 135o wind direction, the base moments of three directions reach to a peak when the deduction frequency is around 0.06, whereas the base torsion coefficient has the second peak when the deduction frequency is 1.1.

Introduction The growing demand in industries for cost reduction and improved quality of the final products have converged to generate techniques aimed at improving or even replacing the existing conventional manufacturing processes, reducing industrial steps for obtaining finished products and therefore the expenses involved in such processes.
In general the advantages are energy saving, reduction of manufacturing steps, increasing productivity and quality [1,2].
Table 3 summarizes the quantitative data obtained.
Data obtained for: a) electromagnetic stirring and b) electromagnetic stirring followed by one equal channel angular pressing pass.

Then sludge pyrolysis test pilot plants were set up successively in 1983 in Canada and in 1986 in Australia, the experimental results show that the sludge pyrolysis can be used to produce fuel, and to provide for the large amount of data to support sludge pyrolysis industrialization.
The review covers pyrolysis conditions, influence factors, products and the application of these products which can provide basic data for sludge pyrolysis.
For the reduction of organic steam decomposition and mutual reaction, shorten the residence time at a high temperature area is effective way.
The liquid yield rate decreased from 53.7% at residence time 0.3s to 43.5% at residence time of 1s at 450 oC, oil yield reduction was caused by the secondary decomposition during high temperature condition.

If these metallic elements are in contact with SiO2, the reduction reaction of SiO2 may occur.
Reported data of activity coefficients in Cu solid solution are summarized in Table 1 [10–16].
In this case, Mn is expected to have a weak interaction with Cu and may have no strong reduction reaction with SiO2.
The average grain size is defined as the mean value obtained from the grain diameter distribution data.

Analysis of Mass Transfer in IR drying The experimental data sets from the different drying tests were initially expressed as moisture content (X) versus time (t).
Experimental data of XR were then fitted to Equation (3).
From Table 1 it can be noted a slight reduction in Deff-values with an increase in air velocity, for any particular IR radiation intensity.
When the infrared heat flux increased from 150 to 450W/m2 the reduction in Sec was about 78% and 55% for air velocities of 3 and 1m/s, respectively.

Civil structures along the time have been suffering damages that imply a reduction on it’s structural capacity, [1].
A typical example of the carry capacity reduction in a structure happens because the oxidation of steel, [2, 3].
To simulate and comprehend this behavior, the applied methodology consisted to draw a diagram moment -curvature, generated by the data that were obtained through a numerical model, a similar methodology that were used by [6,3], but not presented the full model in these publications.
Table 2 presents a comparison between acquired results on rupture tests and theoretical data obtained by the proposed model revealing great concordance.

As a form of corporate responsibility to climate change, energy reduction, waste reduction and zero waste, the company is doing water conservation in the form of recycling activities throughout the liquid waste processing results WWTP (effluent WWTP).
Based on the data base Sima Pro 7.0, most categories of environmental impacts associated with regional and global level, not at the local level.
Principles of AHP is trying to accommodate cognitive aspects, experience and subjective knowledge of decision makers as a basic data to decision making process [3].

The final structural optimisation step is required also to result in a reduction in the total energy of less than 10−5 Ha.
The data for this comparison are presented below.
The change in the relative energies of the different spin states is most likely a consequence of the increased volume associated with the cage site in the ISF, and the additional splitting of the d-orbitals of the iron due to the local reduction in symmetry (effectively an additional local crystal field splitting).
The analysis of the data obtained to date do not show any clear relationship between the strain in the silicon in the vicinity of the Fe atom and the magnitude of the binding energy, and it seemsa/b c a' b' c' d' e' f' g' −0.5 −0.4 −0.3 −0.2 −0.1 0.0 0.1 Binding Energy (eV) neutral positive negative GB sites ISF sites Fig. 3: Binding energy of iron to the ISF and Σ5GB as a function of site (Fig. 1) and charge state.

A detailed survey over the modern literature data led to the conclusion that there is a great interest on imine-based compounds (azomethines), which is directed for the design and synthesis of new structures that can be implemented as new materials for nowadays technologies.
The oligomers O1, O2 and O3 whose structures are shown in figure 1 were synthesized according to the literature data [6].
In DCM, the addition of one drop of diluted HCl solution led to a new absorption band, bathochromically shifted and centered at 548, 540 and 562 nm for O1, O2 and O3, respectively, being accompanied by the reduction of neutral ICT state absorptions.
The successive addition of HCl acid up to 10 drops induced different optical changes for the studied oligomers: the violet DCM solution of O1 has undergone a discoloration to light violet reflected in the UV-Vis absorption by the reduction band from 548 nm along with a 15 nm blue shift.

A reduction of wear by adhesion was detected for both strategies within compression-torsion-tribometer tests.
Specimens are painted in white on the lateral area for reduction of laser interference in the profile measurement.
The measured data is in between the maximum friction factor m = 1 and the sticking conditions.
