Then samples were taken to analyze the bacterial growth and COD reduction.
Component identification was carried out using the NIST 2002 mass spectral library and confirmed by comparison of retention time with authentic compounds and literature data.
Similar data can be generated using the parial 16 S rRNA sequence data set for Sphingobacterium sp.
The value of correlation coefficient (R2) was 0.9534, which demonstrated that the regression curve fitted experimental data well.
Further, as indicated by the data of the inoculated samples after 24h ~ 48h, LMWACs were gradually utilized by strain HY-H probably due to their relatively higher biodegradability.

As the time required for product design decreases, there has been little commensurate reduction in materials development cycle time.
This figure is a schematic based on real data and is for one alloy (Udimet 720).
Similar data are available for other high strength, �’ strengthened Ni-base alloys, so these property dependencies are typical for this class of alloys.

Another potential contribution to SFC improvement and to simultaneous noise reduction, is increasing the engine bypass ratio by increasing the fan diameter.

Nevertheless, there are no sufficient research data to support the use or prove the reliability of degraded tubes/parts on short term service after temperature excursion above Ac1 and Ac3.
The metal temperatures were transmitted, recorded and displayed by a calibrated data logger.
Micro hardness measurement The hardness data following the laboratory aging thermal cycles at different peak temperatures between 7600C and 10000C for P91 specimens are presented in Fig. 14.
This dramatic reduction in hardness was consistent with the microstructure changes to ferritic matrix with coarsening precipitates.

Emission data plays an important part for assessing control measures and development of technology.
Initial Values Databases contain all the data which can be used while Fuel Burn Emissions has the whole results of calculation.
The deviation of individual data reaches about 9%, because actual datasets are abstracted from average values not the data of detailed divided segments, while the computed emissions are very accurate by detailed segments division.
But the relation is not very clear for lacking of adequate data of more other flights the software needs.
The relation between emissions, fuel burn and type of engines is not very clear because of lacking adequate data, but there is no doubt that the relation will be set up and stronger and more clear after in effort to get adequate data of more flights.

Standard quantile characteristics were calculated and compared to historical data.
The results showed that an update is necessary older data because sizes of attributes of Slovak population were increased about 4.5-5%.
The aim of this study is to compare historical data on selected anthropometric characteristics of the Slovak population [4] with recent data, acquired using the same methodology to a survey of adult students in Zvolen in the years 2000-2014.
Basic descriptive characteristics of measured data are illustrated in Table 1.
These were compared to historical data released by [10].

The observed binding energy values are 335.5 eV for Pd 3d5/2 and 340.8 eV for Pd 3d3/2, which coincide with the reported data of Pd (0).
FTIR was used to identify the possible biomolecules responsible for the reduction of the PdCl42- and stabilization of the nanoplates.
Fig. 3 FTIR spectra of the biomass before reduction (a), after reduction (b) and Pd nanoplates (C) The spectrum of the plant extract before reaction (Figure 3a) show a number of absorption peaks located at 1628 cm-1 (C=C), 1447 cm-1 (C–O–H), 1222 cm-1 (C–O–C) and 1037 cm-1 (–O–C–OH), respectively.
After the reaction (Figure 3b), the decreases in the intensity at 1628, 1447 and 1037 cm-1 signifies the involvement of C=C, C–O–H, and –O–C–OH in the reduction process.

Sequences inferred to be from potential sulfur metabolizing organisms constituted up to 70% of the microbial community in the acidic salt flat (data not shown).
In addition, the results suggested the occurrence of dissimilatory nitrate reduction activity (Fig. 1).
In addition, several genes presumptively involved in assimilatory sulfate reduction were identified.
The occurrence of reduced sulfur compounds oxidation, thiosulfate disproportionation, dissimilatory sulfate reduction activity as well as the use of H2S as an electron donor for anoxygenic photosynthesis was inferred.
Conclusions The evidenced microbial processes in the acidic salt flat Salar de Gorbea (photosynthesis, aerobic respiration, denitrification, dissimilatory sulfate reduction) are in agreement with the observations of the microbial diversity in hypersaline (not acidic) lakes.

According to measurement data, and diameter of borehole and water level in the borehole, the in-situ hydraulic conductivity of soil can be calculated Experiment Experimental set up four groups, namely the control group (no surfactant added) and treatment group (0.05g/L SDBS, 0.03g/L CTAB, 0.05g/L AEO9), each treatment for 3 repeats.
Hydraulic conductivity reductions were observed in the test soils with various surfactants added.
The surfactant type effect the reductions of soil hydraulic conductivity, and the nonionic surfactant decreased the hydraulic conductivity most significantly.
The decreasion of interfacil tension in soil/water, the swelling or flocculation of soil, and the agglutination of soil aggreates caused by surfactant could accunt for the reduction of hydraulic conductivity reduction.

Carbon is an ideal candidate as an outside coating material owing to its ease of functionalization, its reduction of the magnetic coupling between individual magnetic metal particles and its stability in acid or base, which may protect the encapsulated metals from environmental degradation.

In order to investigate the relationship between partial corrosion of RC beams and its cracking morphology and flexural capacity, based on experimental data, RC partial corrosion beam models are simulated using finite element software to model the flexural cracks and capacity of corroded RC beam under different corrosion rates.
The results are validated comparing to experimental data.
Notable reduction of yield deflection, yield load and ultimate load for increasing corrosion rate is apparent in Table 5.
A parabolic increase in the accumulative energy absorption at 2 deflection and a linear increase at post 2 are observed in numerical results (Fig.12), which are in good agreement with the experimental data.
