The main reason is that the models are based on poorly obtained data from sample’s digital image processing.
Therefore the importance of setting a new methodology in digital image processing for data acquisition on ceramic morphology analysis is essential for setting new models for customized ceramic synthesis and processing.
Initially a median filter (3x3) was applied for noise reduction.
The aspect ratio data obtained by digital image processing from samples with 55 Vol% was not considered since it does not match the results based on mercury porosimetry as occurred with other samples groups (60 vol% and 50% vol).

A correlation between the structural configuration of Zn3Ta2O8 and the XPS data is also established.
The charging was taken care of by neutralizing with slow electrons and ions during the data acquisition.
The results clearly indicate that electron beam stimulated a reduction of Ta sites on Zn3Ta2O8 surface in the presence of O2 ambient.

This difficulty was surpassed by placing a scale in the machine and using a camera to measure the final height of the hammer, however, the accuracy of the obtained data was reduced.
Similarly to what was stated by Jiun et al. [17] for recycled HDPE from packaging, in rPA6-fn-R2 the slight reduction in tensile modulus and increase in strain at break is related to a decrease in the crystallinity level.
Again, the absorbed water allied with the biotic, abiotic, and photodegradation processes that fishing nets are subjected to, favours molecular weight reduction [5].
The hardness reductions in rPA6-fn-R2 and rPA6-ref-R2 are negligible, considering that these reductions are not significant to choose one material over the other when considering hardness in a material selection.
This chain scissoring effect induces a reduction in crystallinity, resulting in a reduction of density.

The calculation comprises the elements: C, H, O, N, Ar, S, Cl, Na, K with the
thermodynamic data taken from the SGTE Pure Substances Database (Edition 1996) SPS96T02 [7].
The chlorine addition results in a reduction of the dew point.
The reduction is a little lower for K2SO4 with ~43K and 28K for 1bar and 30bar, respectively.
The higher the pressure, the lower is the dew point reduction for the addition of chlorine.
The addition of chlorine leads to a reduction of the dew points of the alkali-sulphates.

Finally, the reason of the micro-vibration in Shuifu county town is discussed and several possible engineering suggestions for vibration reduction are also proposed.
In this paper, the features of the on-site micro-vibration are investigated based on the in situ measuring data.

Nevertheless, according to the data obtained by differential thermal analysis (DTA) the total amount of stored energy in the nanopowder was 348 J/g.
While heating of nanopowder on air desorption of water and gases from the surface and the volume of the nanoparticles occurred with 1% mass reduction.
According to DTA data the thermal effect of Al NP oxidation while heating up to melting temperature is 3549 J/g, the temperature of oxidation start is ~440 °C and oxidation level while heating up to 1000 °C is 53.7 wt.%.
Hence, based on the data obtained by XRD and DTA one can conclude that the forms of energy stored for nanoparticle are both the surface and the stress-strain state of the metallic component, occurred under extreme conditions of nanoparticle obtaining during the conductor electric explosion.

These gold nanoparticles (AuNPs) have been synthesized by the reduction of gold tetrachloride (HAuCl4) using sodium citrate as reducing agent.
XRD data were collected on a Philips X-PERT X-ray diffractometer employing Cu Kα radiation (λ = 1.5405 Å) at 40 kV and 25 mA.
The reduction of gold(III) using sodium borohydride reduction has always ended up with less uniformity in size and shape in this case [23].
The citrated reduction method gave consistent results with highly uniform particle size (22 nm) and spherical shape.

However, the further increasing of nanoclay content of >15 wt% of nanoclay has caused a significant reduction in tensile, elongation at break and optical properties of PLA matrix.
Introduction The use of biodegradable polymers has contributed to a reduction in environmental problems.
The reduction of elongation increase with the increasing of nanoclay contents.
The significant reduction on WVP started with the addition of nanoclay from 10 wt% to 30 wt%.
The data shows a slight, but not statistically significant trend that as nanoclay content increases, oxygen permeability decreases.
