An example reinforced concrete elevated tank structure with flat top cylindrical container and shaft support is considered with the following data: height of shaft support = 30 m, mean diameter of shaft = 3 m, thickness of shaft wall = 0.125 m, inner height of the tank container = 4 m, mean diameter of the tank container = 10 m, thickness of the container wall = 0.2 m, thickness of the container bottom = 0.2 m, thickness of the top cover of the container = 0.2 m, grade of concrete = M25.
Based on these assumed data and considering the elevated water tank structure as a cantilever, the mass and stiffness of the structure are calculated for three cases - the full, half-full and empty conditions of the tank.

The most expensive method to actively raise the pH and concentration heavy metal reduction of this wastewater is the use of chemical additives.
Data Analysis To determine the ability of each parameter in each treatment that was tested by statistical analysis of variance test, Duncan's multiple range test and the effectiveness of the percentage of increasing of pH and reduction in Fe, Mn, and TSS concentrations by comparing the concentration day15th to day1st.
In all treatments of grass species did not show any significant reduction for TSS.
If compared day15th to day1st, only typha grass and vetiver grass show reduction efficiency is 20.3% and 20.2% respectively.
The highest efficiency reduction of Fe on day15th showed by batibati grass is 34.5% then typha grass is 31.6%, purun grass is 27.9% and vetiver grass is 17.4%.

The research groups around the world deal with possibilities of reduction of cement in concrete.
These applications especially cement replacement could lead to CO2 emissions reduction [6].
The inventory data of recycling were calculated according to collected data from Czech recycling plants.
The data of the other processes were taken from Ecoinvent database [11].
The reductions of CO2 emissions were 12%, maximally.

Experimental setup and results
The experimental setup consists of a modified Harrison 300 lathe, a custom-built ultrasonic coupled transducer mounted on a wave-guide, a force measurement system, a band resistance heater, a temperature measurement system, data acquisition system, charge amplifier and A/D converter.
Similarly, HUAT caused a reduction of 36% (from 25 N to 16 N) in cutting force when compared to UAT.
In general, HUAT offers substantial benefits when compared to CT, in particular, reduction in the chatter noise during operations, better surface finish and significant force reduction with good reproducibility of results.
Reductions of 66% (94 N to 32 N) in tangential forces were observed in UAT when compared to CT.
Authors would also like to acknowledge Tampere University of Technology, Finland for providing material data of Ti-alloy.

When the angle of attack reaches preset angle, a signal will be sent to initiate the data collection system.
First, a set of precondition data is taken where the value presents the data of balance, model weight and inertial force.
The values from the preconditional data are subtracted from the values determined in trials with varience in speed and angle of attack.
The differences are the actual aerodynamic data.
So the data slightly fluctuate.

Based on the observation of drilling cuttings data and analysis of geo-chemical testing of a lot of samples in the eastern part of the basin, the content, type and maturity of Jurassic hydrocarbon source rocks were studied, furthermore, the distribution and potential of source rock were discussed throughout the basin The research is significant to the gas exploration.
For the lower Jurassic, the sedimentary and geo-chemical environment (from oxidation to reduction) was unfavorable for the preservation of the organic matter, and another, the lower Jurassic strata was absent in large areas in the basin; Middle Jurassic was favorable for hydrocarbon generation for big thickness, high dark mudstone content etc. in addition, the depositional environment from weak reduction to reduction was suitable for the organic accumulation.
Mid-Jurassic dark mudstone distribution Based on the above analysis, the middle Jurassic sourc rock was most important in the basin, the dark mudstone distribution of middle Jurassic source rock was mapped through the combination of partial and whole data.

Therefore, the aim of the present paper is the
consideration of experimental data relevant in the elucidation of changes in oxidation states of Cu
ions in ZSM-5 structure, found during pretreatment procedures.
A broad absorption band, not presented here, in the spectral region 7500 18000 cm-1 characteristic of Cu 2+ hydrated species was noticed for all investigated samples, which is in accordance with the literature data [6].
All mentioned data (spectral evidences and color changes) suggest that in the case of the samples investigated in this work, Cu 2+ � Cu + thermal reduction is very extended and possibly occurs according to the previously noticed mechanism.
All these data suggest higher affinity for the interaction with CO molecules, at room temperature.
All previously mentioned experimental data are evident: the values of differential heats are much lower in the case of nitrous oxide adsorption, indicating its weaker interaction with Cu(I) in comparison with CO.

According to ERVG data when patients received doxorubicin in a dose of 50 mg/m2 the reduction in LVEF from 57.3±6.7 to 55.0±7.1 (p<0.05) was identified.
According to ERVG data in patients of the first group after administration of doxorubicin in a dose of 50 mg/m2 one could observe a significant decrease in left ventricular ejection – up to 45.8±5.9 % in comparison with 53.6±6.5 % prior to therapy (p<0.01).
In individual analysis of ERVG data it was found that only in 6 out of 14 patients (41%) of the first group during the restudy on the cumulative dose of 200 mg/m2 there was a significant (10% or more) decrease in left ventricular ejection fraction.
Thus, our obtained data have shown that a 10% (or more) decrease in LVEF detected on ERVG in response to the first administration of doxorubicin allows to prognose the development of cumulative cardiotoxicity with sensitivity of 43% and specificity of 85%.
Analysis of data from EGG-PSM with administration of doxorubicin in a dose of 50 mg/m2 has showed a statistically significant decrease in LVEF from 62.2±8.6 to 59.3±7.3 (p <0.05).

Herein, we reported a SERS substrate with alloyed Au-Ag nanospheres prepared via a reduction method of two-step seed growth method in liquid phase.
SERS tests have been performed by the confocal microscope Raman spectrometer system (Horiba, LabRAM HR) with an excitation wavelength of 785 nm, a laser of 5 mW, exposure of 5 secs and accumulation for one time; the power is halved, and 15 points of SERS data is acquired on each sample.
As mentioned above, Au seeds are prepared in the way of liquid phase reduction.
The SERS spectra are obtained with a laser wavelength of 785 nm, laser power of 5 mW, a duration of 5 s’, halved power attenuation and a one-time scanning. 15 points of SERS data have been collected on each sample; the average is calculated as the SERS intensity, and a possible deviation could be avoided.
A 5*5 array has been created from the intensity of the main characteristic peaks and some corresponding ones, and the data are later imported into the PCA [30-33] algorithm, thus the variance contribution ratio and the cumulative variance contribution ratio could be obtained.
