The formation of hydrated phases leads to the reduction of distance between the grains and the viscosity of paste is enhanced.
They are immobilized (stabilized) in hydrating cement paste, due to the physical and chemical properties of cement matrix; therefore a significant reduction of leaching (up to ppm level) is guaranteed [3].
As it is commonly known in cement chemistry, only the calorimetric measurements give the possibility to follow the changes occurring in the hydrating mixture produced at standard water to cement ratio in a continuous way from the beginning of the process, without removal of water (e.g. for the phase composition studies the so-called “chemical drying” should be done and the data obtained vs. time are of discrete character).
Every retarding admixture brings about the reduction of heat evolved value increase throughout some period of time at early age of hardening (it means even up to 2 days).

The enrichments were characterized by denaturing gradient gel electrophoresis (DGGE) of 16S rRNA gene fragments and sequencing, and microbial oxidation and reduction activity were tested by pH and Redox potential changes and KMnO4 methods [5].
Iron and sulfur oxidizing cultures have been enriched where Acidiothiobacilus, Acidiphilium, Leptospirillum and Oxalobacteraceae have been observed (data not shown).
Microbial arsenic and sulphate reduction (AsRB and SRB) was evidenced only in the locations with the highest pH (4.7-5) and was absent in the abiotic controls.
The distribution of AsRB in that environment suggests a critical effect of pH on sulfate and arsenic respiratory reduction.

Then the bone reduction process was used to detect the fracture area and fracture line.
The fracture line meshes determined by the bone reduction process have only a series of triangular planes of no thicknesses, and the slicing software cannot be used to generate the deposition paths.
However, the fracture line is based on data obtained from the fractured bone mesh model.

This is reached in the real process in an incremental manner (increase of the height in the radial rolling gap, reduction of the height in the axial rolling gap).
But it confirms the strategy that the compaction behavior can be improved by increasing the pass reduction at the main roller.
In addition, this control mechanism has been utilized to set up a well-defined relocation of the ring during the rolling in order to influence the pass reduction at the main roller and the mandrel with the aim to reach a high compaction level of the layer material at an earlier stage (see left part of Fig. 7).
Fig. 8 (right) also presents the setup for the following practical tests for evaluation of the calculated data.

As a good approximative description on the exchange-correlation energy, the local functional Ceperley and Alder data as parameterized by Perdew and Zunger (CA-PZ) [11] is chosen.
With increasing Co content, Fe and V AMM suffer a rapidly nonlinear enhancement and reduction respectively, which is responsible for nonlinear change of TMM.
Moreover, a slightly linear reduction of AMM from 2.0 to 1.9μB for Co atom and from 0 to -0.06μB for Ga atom is also detected.
While as x>0.5, except for a prominent reduction of spin-up peak and enhancement of spin-down peak at 0.5eV, the DOS shape only suffer a small adjustment without prominent movements of energy bands.

In the region below 200 mV, in the course of studying the reverse branch of cyclovoltametric curves, gaseous hydrogen was observed on the surface of the oxide electrode due to the reduction of hydrogen.
During the secondary and subsequent voltage application (Fig. 1, colored branches) in the range from minus 150 to plus 450 mV, a reversible change in the transmittance of the samples occurred, corresponding to oxidation and reduction of nickel β hydroxide.
Samples obtained in the (EtCp)2Ni–О3–О2–Ar system at 680 К showed a change in optical density of 0.42 ÷ 0.65 and a staining intensity of 26.9 ÷ 30.7 cm2C-1, comparable with the literature data for nickel oxide layers (20 ÷ 40 сm2C-1) [5] and stability in cyclic tests for 1.5*104 cycles.

In addition, the injection pressure increased with addition in injection well and reduction in absorption water capacity.
The relationship between corrosion rate and time was established on the base of experimental data, as shown in Fig. 1.
Further observation uncovered the process of reduction in basal body.
