The reduction was performed using carbon as reducing agent.
The reduced calcines with different reduction degree were gained by varying the reduction temperature, reduction time and the amount of reducing agent [11].
Results and Discussion Effect of Reduction Degree of Calcine.
The effect of reduction degree of calcine on the leaching process is shown in Table 2.
The data reported here suggest that using released acid from iron ion hydrolyzing as leaching agent for the reduced calcine is feasible.

This study shows that a wear analysis on the base of a strip drawing test allows reproducible data.
The roughness data are shown in Fig. 2 (left).
The geometry data of tool I-III also show small deviations of less than 0.1 mm.
The development of these data is given in Fig. 4.
These data are a good indication for the current state of wear.

Therefore, choosing an effective technology of frequency reduction is necessary.
The envelope detection technology is an important part of this ultrasonic data collection system.
Experimental Study The device as shown in Fig. 2 namely is the ultrasonic data collection system which can realize the acquisition of the ultrasonic signal and complete the frequency reduction of the ultrasonic signals.
PCI8664 data acquisition board is used to collect data coupled with the software labview.
Utilize the system to get the experimental data by testing on the ball bearing of a small AC motor.

Experiments are carried out in two phases on a DICI engine test rig which includes CI engine, electric loading device, exhaust gas analysers, and a data-acquisition system.
They reported that slight improvement in brake thermal efficiency accompanied by the higher reduction in NOx emission.
The test rig is constructed by using an air cooled, naturally aspirated, four stroke single cylinder Direct Injection Compression Ignition (DICI) engine, alternator, loading device, exhaust gas analyzing unit (Di-gas analyzer and smoke meter), fuel metering unit and a data acquisition system.
The data acquisition system comprises a pressure sensor to measure the cylinder pressure, and personal computer with data processing software.
The intrinsic oxygen contained by the Pongamia and Jatropha biodiesel was responsible for the reduction in HC emission.

Lead Time Reduction through Execution of Lean Tool for Productivity Enhancement in Small Scale Industries V.
In a gear manufacturing industry, value stream mapping and line balancing were adopted as an idea for reduction of setup time and cycle time.
Fig. 1: Different Phases of SMED Data Collection and Analysis Data collection was carried out in injection moulding machine production process flow setup time.
The time taken for fastening tie bar could be mostly reduced by the proposed design and the time reduction as follows
The net total of 27.05 minutes has been reduced and the percentage of reduction in setup time achieved was 67.72%.

The technique analysis the sum of squares(SS) instead of the data.

Comparison of FEA results with experimental data: (a) frequency spectrum, (b) radiation pattern.
The results in Fig. 4 was used as the reference data to evaluate the efficiency of structral schemes to reduce the cross talk level.
However, to be more specific with the data, cross talk was smallest when damping ratio of the wall was 1.0.

The results showed that Fe3O4 was catalytically active in NOx reduction.
The third is the NOx reduction technology, which is a method of NOx reduction by controlling the operational condition or mixing some additives with raw material.
The data were recorded every 30sec from the start to the end of coke combustion.
By calculation, The NOx reduction ratio increased with the Fe3O4 loading, the NOx reduction ratio reached maximum value—15.05% as Fe3O4 loading was 2.0%， then the NOx reduction ratio decreased with the Fe3O4 loading.
The NOx reduction ratios were 17.85%, 18.97% and 17.85% respectively.

A preliminary numerical analysis showed a reduction of deflections of reinforced beams by about 11 to 14 % and a reduction of 19 to 25 % of normal stress.
Glulam beam strengthened with aramid cords Material data.
Aramid rope material constants adopted on the basis of data presented in [9].
The data adopted for the calculation are presented in Table 1.
Only in tension zone strengthening with two layers of cords cause reduction of 25 % of normal stress in comparison to a non-reinforced beam.

Rapid microbial sulphate reduction (within 50 days) was induced in the tests containing nutrient-amended lactate, cheese whey and soy oil.
For the condition containing glycerol and aquifer solids from 30 m-bg, an increase of both pH and fatty acid concentration (data not shown) and a decrease of redox and sulphate concentration correspond with a decrease of Zn (Fig. 1B) and Cd concentration.
A summary of all data obtained within 106 days of treatment are presented in Table 4.
In the other conditions there was no removal of Mn and Co (data not shown).
Nevertheless, Ni was removed similarly in all conditions (data not shown).
