There was a significant improvement in flexural modulus and a
marginal reduction in flexural strength of epoxy matrix due to the incorporation of organoclay.
Compliance, C, values were calculated from the load-displacement data and the intercepts, ∆, with the abscissa were determined experimentally from the least square plots of cubic root of compliance, C 1/3, against the crack length, a.
The improvements of flexural modulus were at the expense of reductions in flexural strength due to clay agglomerates and non-uniformly distributed clays.
Within the data scattering, the flexural modulus increased whereas the flexural strength decreased with increasing clay content, although the variations were marginal compared to the other properties.

The refinement of the microstructure and reduction of the
volume fraction of the η phase up to 1.7%, as compared to 4% in the mould cast alloys was
observed in the ribbons.
According to the data presented in [9], the maximum extension of a solid solubility by rapid solidification could increase up to 1.5 at. % while the maximum equilibrium solid solubility is 0.083 at. %.
Peak positions for the η phase were shifted towards higher 2Θ angles, as compared to the catalogue data for MgZn2 phase.

Abstract: With the datum of output, energy consumptions and environment pollutions of 36 industries of HeBei Province during the period of 2005-2007, we first calculated the marginal values of GDP contributions, energy consumptions and environment damages each industry played on the whole provincial economy.
Using the data of 2007, we calculate the marginal damage and its average of wastewater and waste gas of 36 industries, respectively.
All data come from "Hebei Economic Yearbook".

Maintaining their pivotal role in the economic development and at the same time deeply enhance the quality of their growth through further reductions in energy consumption and waste emission.

A data review on slags at the production of chromium and manganese-containing ferroalloys are given in the work [6].
The recommendations for optimizing the modes of smelting high-carbon ferromanganese and silicomanganese in ore-reduction furnaces are presented.
Thus, it was not found any data about the study of the manganese recovery carbothermal process from the multicomponent CaO-SiO2-MgO-Al2O3-MnO-Fe2O3 system at the manganese slag addition.

The obtain simulation results indicate that the proposed model is able to approximate the geometric deformation and the relative density distribution; using only accumulated LDR’s as input data.
Furthermore, a relative density reduction at the constrained corner (point 3) in the 2D geometry and the 3D cuboid was obtained.
The following observations support the previous statement (i) stresses showed no reduction at the end of the sintering process, (ii) the largest Von Misses stress for a sintering time equal to 12000 s was located near the free corner and (iii) the magnitudes of both stress norms used are considerably lower in 3D simulations.
Free sintering data was taken from ref. 2.
In the opposite case a local relative density reduction was observed.

As the solubility of neutral metals in glasses is low compared to the initial ion
concentration [4], the reduction of metal ions leads to essential over-saturation of the glasses by
neutral atoms and then to the nucleation and growth of metallic nanoparticles [5-7].
The capture of hydrogen H 0 in a trap, in which it loses electron and becomes ion H + forming OH bond, is accompanied by appearing neutral silver atoms (Ag 0) according to reaction [11] ≡Si - O - Ag + + ½ H2 → ≡Si - O - H+ + Ag0 (1) The equation for neutral hydrogen diffusion with traps is: 3/2 00 2 0 2 0 0 + − ∂ ∂ = ∂ ∂ AgHH H H H CCpD x C D t C , (2) where CH0 and CAg+ are the concentrations of neutral hydrogen and silver ions respectively and p is the coefficient, which describes the probability of silver ions reduction.
The diffusion of neutral silver, which appears due to the reduction of silver ions, is accompanied by the formation of silver clusters because the solubility of neutral Ag 0 atoms in a glass is low compared to the content of Ag + ions.
Initial data for these calculations were chosen in accordance with literature [13] and experimental data obtained by the authors earlier.

We considered Manik's work [7] very interesting to compare with; he was
the first researcher who investigated structural changes in high-energy-ball-milled ZnO-TiO2 by the
Rietveld analysis of XRD data and obtained zinc titanate after 30 minutes of activation.

Tribophysical activation leads to the reduction in cohesive dispersion domains for all directions observed, the number of defects within the material rises and that reclaims the diffusion of ZnO and TiO2 atoms, which leads to a solid-state reaction.
Analyses of microstructure parameters calculated from the XRD data indicate that the most intense changes are present in the ZnO lattice and it is obvious that the crystallite size of ZnO decreases during the milling process, for all three directions observed here.
Also, it has been found that tribophysical activation leads to particle size reduction, the increase in dislocation density and lattice strain.

Kuznetsov and colleagues [6] suggested that this reduction in lattice damage is due to the annihilation of vacancies and interstitials created during implantation.
The data clearly demonstrate a reduction in strain with increasing implantation temperature due to the dynamic annealing effect.
Therefore, the flux or dose rate of implantation employing EFII can be much smaller than that of multi-step high energy implantation, leading to reduction of the lattice strain after implantation for wafer implanted with EFII.
