The results indicated a reduction in the void content when the percentage of waste glass increased to w/c ratios of 0.55 and 0.58.
The reduction of the void content reduced the concrete’s W/A and increased its specific gravity.
According to data from CEMPRE (a Brazilian business association dedicated to recycling), Brazil produces around 980,000 tons of glass packaging per year, using about 45% of recycled raw material in the form of shards.
The concrete composition prepared with the w/c ratio of 0.50 showed an increase in the void content from 5% to 20% of glass and a reduction in the void content from 0% to 5% of glass.
For w/c ratios of 0.55 and 0.58, the increase in waste glass content in place of fine aggregate led to a reduction in W/A due to the decrease in the void content, as indicated in Figure 2.

The amount of reduction of the detonation threshold depends on the geometry of the void.
For square voids, there exists a minimum size above which reduction of the detonation threshold occurs.
For voids with a small longitudinal dimension, there is no reduction of detonation threshold.
After removing these initiations from the data, the detonation threshold curve for L voids overlaps very well with the other two curves.
This causes a reduction of the detonation threshold of an energetic crystal containing a void.

Models are validated with supersonic nozzle data and wall impinging jet mass transfer data from literature.
The adjusted model was tested with NASA supersonic jet data [6,7].

In order to ensure the accuracy of the data analysis, the different forms of contain Mercury samples method research and analysis, acquired the production data of the system and make check set the options laid a foundation.
Considering the 100000 t/a PVC device has been put into production more than 2 years, in the short term to find PVC device mercury balance, get a complete and credible data have great difficulty.
In the process of the flow of mercury art investigation and inspection, contain mercury wastewater treatment of device check, operation data detection, a total of 12 has more than 700 data.
Prison the data show that the production environment atmosphere within the device testing results is low, far lower than the harmful factors workplace occupational exposure limits part 1 chemical harmful factors "(GBZ 2.1) limit.
Shall check In the preliminary check for process, according to the monitoring data of continuous adjustable the whole scheme, respectively, aiming to take common key monitoring, sustained attention and so on way.

Data was collected using monochromatic Cu Kα1 radiation (λ = 0.154 nm) over a 2θ range of 30-100°.
The modified Williamson-Hall method [2] was then used to determine dislocation densities from the fitted data.
X-ray line broadening measurements were used to estimate the increase in dislocation density after stretching and artificial ageing. 2θ scans of the {111}, {200}, {220} and {311} diffraction peaks were performed to obtain high resolution diffraction data and a Pseudo-Voigt function was subsequently fitted to each diffraction peak, in order to calculate its FWHM.
Overall, this data indicates a reduction in plate diameter with pre-strain, a narrowing of the size distribution, and a corresponding increase in precipitate number density, that continued to the high pre-strain levels investigated in this study.

(2), using dislocation densities measured by XRD, compared to the T4 tensile stress strain curve, (b) the strength contribution from the T1 phase ( Eq. 3), using TEM data, compared to the expected yield strength if strain hardening is deducted.

The numerically gained results are validated by experimental data.
This paper shows an evaluation of possible methods to simulate the cutting operation in a commercial available simulation program and the validation of the results by experimental data.
Therefore the experimental data is measured using the microhardness measurement system Fischerscope® HM2000.
Preliminary results show a good match of experimental and simulative data.
By validating a suitable element removal threshold with experimental data it is possible to analyze different tool designs for a given material combination.

The reduction of the crystallization temperature is one of the procedures in this direction.
Calcination must be carefully controlled since the adopted conditions (temperature and time) might influence powders physical characteristics as well as nickel oxide reduction during reforming reaction [3].
Crystallization of gamma alumina and NiAl10O16 powders started at 150ºC, as indicated by the comparison of diffraction data with ICDD cards 10-0425 and 37-1292, respectively.
These diffraction data are in agreement with literature [10,11].
Increase in calcination temperature led to a reduction in surface area, which is related to particle growth.

In electrolyte containing ammonium chloride was observed direct reduction chetyrehjadernogo emeakaroha complex, as well as recovery of oxide copper (I), formed, apparently, from single-charge complexes, appearing for due to the recovery of two-charge, due to the alkalinization of the electrode layer (Fig. 2a).
Discussion of Experimental Data For obtaining of ultradispersed powders of copper electrolyte source were: ammonium chloride solution; ammonium chloride solution containing polyvinylpyrrolidone in an amount of 20 g/ l; ammonium chloride solution containing also polyacrylamide in an amount of 40 g/l.
In an electrolyte containing ammonium chloride and polyvinylpyrrolidone, the process the formation of powder particles is accompanied by the reduction of unbound copper ions (II).
Also in the process of obtaining Cu2O is restored, which is formed in the near-electrode layer due to the partial reduction of copper (II).
