The aim of this
work was to evaluate the feasibility of the system, with real AMD from Zijinshan Copper Mine and
to provide data for the technical and economical evaluation for a larger scale.
Fig. 5 shows the fraction of COD utilized for sulphate reduction, as well as the fraction of organic COD remaining in the effluent as a function of time.

The
reduction of tube thickness is caused by fretting wear, which may threaten the safety of
components [3].
After the tests, the change in the wear scar of the tube was recorded by using surface profile meter and these data was used for estimating approximate wear volume.

After milling for 4-16 h, the diffraction peaks of Ti broaden while their intensities decrease, suggesting that reduction of the average crystallite size, buildup of defects and formation of internal strains.
According to the thermodynamic data for the different reaction species provided in the literature [7], the room temperature molar Gibbs energy of TiN is -346.89kJ/mol, which is lower than that of -191.32 kJ/mol for TiC.

It is true that the major driving force for abnormal grain growth is the reduction
in grain boundary energy, but an additional driving force may be needed to overcome the
circumstance that normal grain growth is being inhibited [5].
Figure 4 shows the OIM maps and the inverse pole figures recalculated from the OIM data, obtained in the Fe-36%Ni alloy electrodeposit which was heated up to 390°C and then instantly cooled down to ambient temperature.

The data are analysed using
the Rietveld method [3].
The details of the complete data sets acquired are given in table 1.
(b) Data sets 3, 8 and 9, 8 being the middle of the three.
Grain growth was most rapid near data set 100 (Tmax) as would be expected.
Phase Evolution During Sintering of 17-4PH Sintering data sets The recorded temperature profiles for three data sets for 17-4PH are shown in Fig. 1b.

The kinetic data was well fitted with the Elovich equation with error 1.6 x 10-4.
(2) 2.4 Calculation 2.4.1 Kinetic data analysis.
We can say all models were fitted with the experimental data with some error.
The Freundlich equation was the second-best fit to the experimental data.
The Elovich kinetic model showed the lowest error with experimental data.

These probes were then connected to a data acquisition and recording system.
L [m] Wall length Project data Should be measured the length of the wall (Lwall) in the building plan.
If there is no available T data inside the system, it can be used the T value inside the building

Replaying
The attacker intercepts and captures data, re-transmits data, and thus obtains permission or swindles a reply.
However, data inside a network were not encrypted.
Message authentication code (MAC) is generated by forming new data blocks via the keys from the messages to be authenticated, and then by encrypting the data blocks.
Depending on the user's and data security levels, it decides whether a user has the authority to access to these data.
Check whether the data from the redundant nodes are consistent.

All the gathered data should allow an interpretation of the gradual change in time of the structure’s physical reality, of its technological conception and of its structural behaviour since the original design by the carpenter or engineer, through the subsequent works or “natural” evolutions, unto the current state.
Instead, with regard to the investigations that are carried out locally only, the choice of the points in which execute them is even more crucial, since it is necessary that collected data are significant for the entire structure or for specific critical points (e.g. measurement of moisture content).
The survey of the geometry of the structure The detailed survey should not be only a gathering of metric data about the geometry of the structure and it should not only provide a graphic support for recording data of subsequent investigations: it must be the first step towards the critical interpretation of the structural complex.
On the other hand, the use of thermography can provide only qualitative data, but in a simpler way, thus being useful for identifying critical areas in which to perform the measurements with electrical resistance hygrometer.
