Existence of a novel
Hg2+ -reducing enzyme system, in which mercury resistant aa3-type cytochrome c oxidase
catalyzes the reduction of Hg2+ with reduced mammalian cytochrome c or Fe
2+
as an electron
donor to give Hg0, has been shown in iron-grown MON-1 cells.
There has been no reports on the mechanism of Hg2+ reduction by sulfur-grown A. ferrooxidans cells.

The NRS extracts useful information based only on the data itself, and is used for redundant attributes reduction to make the selected features more objective.
But Pawlak’s Rough sets originally proposed to deal with categorical data, for numerical data must be processed after the discretization.
First, each attribute of the data sets are normalized to the range of 0~1, and then divided into two parts randomly, 60% of the data as training sets, 40% of the data as testing sets.
From Table 4, when the samples of the data sets are certain, the reduction features effectively shortened the operation time, especially for the data sets which have more samples, such as DALL, the effect became more obvious.

Through the analysis of existing data, the shaft tower vibration characteristics and seismic behavior research is analysed and forecasted.
All of these four scheme have a better vibration reduction effect more than 80%.
Dynamic tests conducted on a R.C. shaft tower erected by the “preconstructing and wholly shifting” method under the conditions of non-fixed, wholly fixed and partially fixed basements, and analyzes the dynamic characteristic discrepancies of the free vibration frequencies, damping ratio and vibration modes measured by different test recording methods as well as the effects of fixation conditions of basements on the dynamic characteristics of structures, providing the reference data for the design of shaft towers in [15].
It is induced natural vibration period experience formula [18] suitable for more than 60 tower tower data as the sample built in China 's representative which had measured the vibration period, through the regression analysis of mathematical statistics method fitting out two for 20 meters to 65 meters in tabl.1.

Abstract: Titanium concentrate and titanium slag were used to prepare high titanium ferroalloy to reduce cost.
It was prepared using of scrap metal titanium, but the shortage of resources of scrap metal titanium has seriously hampered the yield of it. (2) Metal thermal reduction method[2,3].
Rutile, titanium concentrate, aluminum powder, (or magnesium powder and other metals) were used to prepare high titanium ferroalloy by thermal reduction method.
Table 3 The influence of ratio of raw materials on the experimental data Titanium concentrate [g] Titanium slag [g] Aluminum [g] Lime [g] Fluorite [g] BaO [g] B2O3 [g] KClO3 [g] Weight of titanium ferroalloy [g] [Ti] in titanium ferroalloy [%] [Al] in titanium ferroalloy [%] 150 350 290 45 15 5 10 80 153.0 62.2 4.3 100 184.6 66.4 4.1 125 175.5 67.7 5.9 Ratio of Magnesium.
They will make TiO·Al2O3 to be formed very difficult, and promote the Ti reduction [6].

The data showed that L. ferriphilum was able to utilise ferrous iron at low-level concentrations of SCN- (0.25 mg/l to 1.75 mg/l), however exhibited a reduction in oxidation rate relative to the control (0 mg/l).
Historical process data suggests that the biooxidation community is highly sensitive to SCN- with the empirical limit supposedly 1 mg/l [2, 3].
To date, no kinetic data or information pertaining to the iron oxidation performance of L. ferriphilum in the presence of SCN- is available.
The data indicated a decrease in oxidation rate compared to that of the control.
Sensitivity of L. ferriphilum is evident from the data presented in Figure 1 and Table 1.

Introduction
Since the beginning of Ti alloy production in the late 1940's, Ti sponge has been produced by either
the Kroll (magnesium reduction) or Hunter (sodium reduction) processes [1].
The inspection data clearly reveal the handling defects (~50µm in size, identified by arrows) against the almost zero background noise levels.
Tensile data from this material, Figure 3b, showed a 0.2% yield strength of 1035MPa, an ultimate tensile strength of 1170 MPa and a plastic elongation to failure of 7 percent, while the modulus was about 117GPa.
Highcycle fatigue (HCF) data obtained from this material is shown in Figure 3c, where it is compared to identically tested AMS 4921 Grade 4 CP Ti bar, and literature Ti-64 data [5].
The data show meltless Ti-0.9B material has a runout stress (10 7 cycles) 275 MPa greater than CP Ti, and 240MPa greater than Ti-64 bar.
