In this paper, data of different microbial populations in the coal spoil substrate and geochemical background data are given, and they are compared with former data of microbial communities in sandy substrates and their impact to the environment.
The obtained data correspond well with a parallel and long-term monitoring of ground water in the coal spoil area which is characterized by high concentrations of SO42-, Fe and NH4+ and an enhanced acidity [3].
Therefore, a reduction of the high oxidation potential, acidity and salinity by sulfate reduction processes is too slow under the actual conditions and will show no substantial changes in the next future.
In the sandy Lusatian spoil material, only from a depth of 12 – 15 m a complete sulfate reduction was detected [1]; in the oxidation zones above no sulfate reduction could be shown.

They are beneficial for data representation and classification and have been widely used in recent years.
These improved subspace algorithms not only describe the nonlinear structure of the data well but also can project new data points directly.
Supposing represents the high-dimensional space of the original data, is a low-dimensional manifold embedded in , and , for a low-dimensional mapping function , to maintain the intrisic geometrical structure of the data manifold, find a function that meets the following condition
The IsoProjection algorithm is able to describe the manifold structure of the data and extract useful information from the data for classification, so its recognition performance is better than PCA and LDA.

The HDH plate was rolled only to 75% reduction in thickness.
This is reasonable since the HDH product was formed using HIP forming methods and not by sintering. [20] Figure 4 shows a table of Charpy Impact data (A) and a histogram of the same data (B).
This was significantly lower than both the blended elemental sample rolled to 75% reduction, 34.03 J (25.06 ft lb), and the prealloyed HDH powder sample also rolled to 75% reduction in thickness, 33.19 J (24.44 ft lb).

The network data was obtained and modeled on NEPLAN software for simulation and technical evaluation of the networks.
The study concluded that a further reduction in technical losses was achieved with an increase in system efficiency.
The data for the purpose and analysis is taken from [15]. 2.
R ∝ L A or R = ρL A (4) Where R is the resistance of the conductor, L is the length of the conductor, A is the area of the conductor, ρ is a constant depending on the nature of the material of the conductor and is known as its specific resistance or resistivity The load data and line data for modelling the Ajilosun 38-Bus distribution network is shown in Table 1 and 2.
The line parameters used for the extension of aggregated load points in the simulation model is given in Table 3, and the transformer reactance data used in the modelling is given in Table 4.

Then, (7) Here, is thickness reduction rate.
The average thickness reduction rate in each portion is used in correction same area method come from finite element analysis for the workpiece.
The average thickness reduction rate in each portion is taken into account in the strain calculation.
We can obtain the average thickness reduction rate in each portion through finite element analysis or experiments. 3) The data on strain obtained from the deep drawing forming experiment show that the strain curve from correction same area method is close to the experimental strain curve.

In a threshold region a significant shift in the data of the fatigue crack propagation rate can be observed.
To analyses it the authors will present their own laboratory fatigue crack growth rate test data measured on two different specimens with different levels of constraint and for different steels.
The authors will present their own laboratory fatigue crack growth rate test data measured on two different specimens with different levels of constraint and for different steels.
Because load reduction occurs gradually as the crack grows, no true threshold is reached in a practical amount of time.
