The experimental data shows that the desorption of weakly bonded impurities, mainly H2O, takes place below 200°C both in diamond and SiC powders (Fig.1).
The oxidation is observed as a reduction of the oxygen in the outcoming gases and, at the same time, an increase of emission of carbon and its oxides from the samples is observed.
From SAXS data one can also deduce the relative positions of individual nano-objects present in the material.
The data is presented in Table 2.

That is necessary for technological difficulties reduction in obtaining a bimetallic strip.
The results of the experimental data have determined the supreme total strain under which the cladding strip ruptures occur.
The experimental data, presented in Fig. 2, are approximated by the least-squares method.
The results of the experimental data are approximated by the method of least squares.

In recent years, neutron scattering data in liquid alloys and metals have become increasingly available.
Moreover, for both S(q) and g(r), slight amount of reduction in principal peak is observed with increasing Sn concentration.
In lieu of experimental structural data to us, we believe that the reported data will provide a better source for further investigation, and may serve as the means of comparison.

Data Reduction To evaluate the thermal performance of the interlocking block solar collector will be calculated in term of efficiency, which is defined as the ratio of useful energy to solar intensity on the wall, it can be estimated as equations: h = Qu/AcIb (1) Qu = AcFR[S-Ul (Tfi-Ta)] (2) where: h is the efficiency (%), Qu is useful energy (W), AC is area of collector (m2), Ib is measured solar intensity on the collector (W/m2), S is absorbed solar radiation on the collector (W/m2), FR is collector heat removal factor [6], Ul is overall coefficient of heat losses (W/m2.
Thermocouples type K (range: 0-1250°C, accuracy ±0.5°C) were installed at different positions (figure 3), the thermocouples were connected the data logger (Hioki, Model: 8422-52, accuracy ±0.8%).
The data were recorded every 30 minute.

All the experiments of CuNPs-Pl synthesis and optimization were performed in triplicate run whereas antimicrobial and antioxidant assays were experimented in five runs and data was statistically expressed as mean ± S.E.
It is believed that the reduction process is increased as the volume of extract increases which is responsible for fast nucleation resulting in the small size nanoparticles.
Several functional groups have been revealed in the FTIR spectral data of PlL and CuNPs-Pl as shown in Fig. 4 (A).
DPPH assay principle involves in the reduction of DPPH radical to DPPH-H non radical form which indicates from the color change from purple to yellow.

The histogram results also demonstrate that the Co3O4-NPs possess a relatively larger average particle size compared to the crystallite size estimated from the XRD data.
For further elucidation, the experimental data were fitted by a pseudo first-order kinetic model using the equation, ln(At/A0) = -kt, where At and A0 represent the absorbance of MO dye at time t and at the initial state, respectively, and k is the rate constant of the reduction reaction [57, 58].

In this theory, we can know the “sustainable” developmental potential of human race in one area by obtain the ED data.
It should be that our development is “endurance” when the ED data is “ecological gain” but not “ecological deficit”.
According to the ED data, there were still 12 provinces and cities of China are “ecological surplus” in 1980.
It is just like different tunes sung with equal skill with the modern composite wall which is especially designed for energy saving and noise reduction.

The unknown parameters in LuGre model are main depend on the contact feature of the interfaces, and usually can be identified from measured data.
Simulation data was acquired at two force levels for random excitations and two frequencies for sine excitations as shown in Table.1.
By the statistical analysis of this simulation data, the vibration amplitude was restrained effectively by friction force.
Through investigation, we arrive at the following conclusions: (1) Friction can be used for vibration reduction, which absorbing is good and vibration damping is rapid

The 2507 SDSS is not recommended for applications which require long exposures above 300°C because of the risk of a reduction in toughness.
The magnetometer is completely computer controlled, the measurement and the excitation are performed by a National Instruments data acquisition card (DAQ) and a PC.
The data acquisition, processing and the control of the set-up were done by a LabView VI.
