It is found that fly ash registers a SiO2–Al2O3–metal oxides system and its content of glass phases is around 57% which is conducive to reduction of energy consumption in its recycling process.
Based on the above studies, this work performed analysis of chemical, elementary and radical component transformation to provide valuable data for fly ash thermal treatment. 2 Experiment The ash used in this study came from the biggest municipal solid waste incinerator, Jiangqiao MSWI Plant, which handles 1500 t/day.
Hence, they are conducive to reduction of energy consumption in making of fired construction materials, such as glazed tile, ceramic brick, ceramic glass and etc.

Oxygen-reduction at the cathode could be carried out effectively with the assistance of catalytic action by bacteria, enhancing the electrochemical properties of the cathode.
In these microbial-anode MFCs, noble-metal (e.g. platinum) based catalysts are still used to increase the rate of reaction of oxygen-reduction at the cathode as in electrochemical fuel cells, which create an obstacle for practical applications of MFCs due to high cost of electrode materials.
Voltage and electrode potentials (versus saturated calomel electrode, SCE) of MFCs were continuously measured using a multiple-channel data acquisition system (PIO-821H, Chengdu).

This may indicate that the interfacial region effect increases with milling time due to the grain size reduction and to the disordered state of the interfacial region.
The interpretation of the main components in the Mössbauer spectra can be made with a perusal of literature data for Fe–Mg compounds obtained by non-equilibrium techniques: mechanical alloying [1-8].
In contrast, Hightower et al [8] have found that there is no significant difference between the estimates of Mg solubility in Fe from the XRD and Mössbauer data for MA samples.
After 36 h of milling (see Fig. 4e), considerable refinement and reduction in particle size is evident.
We observed the absence of hcp Mg peaks after 4h of milling and a monotonous reduction in the grain size down to 9 nm after 54 h milling time and an increase in the micro strain up to 1.11%, together with a slight increase in the crystalline lattice parameter to 0.2884.

The parting paint effectiveness is determined by defect reduction of the castings on the core blow, uncertainty in geometry, metal penetration, and also the use of available and environmentally friendly molding materials in their composition, that makes the product to be highly competitive.
The complex contains a software suite for computer processing of measurement data.
Their use provides considerable defect reduction (in core blows, uncertainty in geometry, metal penetration and etc.) in steel and cast-iron high-duty mouldings and improvement of environmental situation in the floor.

The extrusion has been successfully conducted at the temperatures of 300 oC and above with the ratio of area reduction of 28 and 40.
Recently, hypereutectic Al-Si Alloys have been recommended as a strong candidate material for the cylinder liner of engine block in automotive industry in the light of automobile weight reduction.
Figure 3 shows the relations between the extrusion pressure and ram-speed for the extrusion ratios of r = 28 and 40, obtained from equations (1) and (2) using the flow data in Fig. 2.

The method of active queue management arithmetic which solves full queue of routers is dropping arrived data packets before the queue is full so that end-note is able to respond before the queue overflows, avoiding the actual occurrence of congestion.
When congestion happens, data packets queuing in router reach the limit that buffer area can contain, leading to the overflow of buffer area, and routers begin to drop newly arrived data packets.
At this time, data packets delay increases, drop ratio grows and network efficiency reduces.
The fundamental cause for network congestion lies in that network load provided by users (also called end system) is greater than the network resource capacity and processing ability, with the representations being increase in data packets delay, augment in drop ratio and reduction in performance of top layer applicable system.

The performance data considered where the evaporator cooling load, the condenser heat rejection, the electrical energy consumption, the refrigeration system temperatures, and the room temperature.
Data was collected on when the conditions are considered stable, after the air-conditioning was running 15 minutes for each test condition.
The system was installed to a simulation room, together with a data-acquisition system to monitor temperature of the room.
At the time of the beginning data collection, this was 15 minutes after the air conditioner was operated, the COP of R-22 lower than that of HCR-22.
Based on the data described in the previous section, it was indicated that, a drop-in from R-22 to the HCR-22 may reduce power consumption of the compressor and increasing of cooling capacity.

In the initial operation stage of some ore wharf, the silting situation appears in the wharf apron; through the on-spot hydrological, geological and topographic survey and combination with a lot of previous data and the project implementation, the research is made into the hydrodynamic sediment conditions in the water area and the changes of topographic erosion and siltation.
Deploy 14 measuring points on 3 sections near the waters of the ore wharf (Fig.1), adopt ADCP underway measurement to observe the quasi-synchronous tidal current field at the wharf and nearby waters, so as to provide the fundamental data for the analysis of the reasons for the wharf siltation.
Analyze the water-sediment environment in the waters of ore wharf according to the previous data and the latest measured data, and master the evolution of the siltation in the wharf waters for the past few years, so as to provide the basis for the analysis of the siltation reasons.
According to the measured data in September 2011, the average sediment concentration of the spring tide, moderate and neap tide in the wharf water was 0.07 kg/m3, 0.04 kg/m3 and 0.04 kg/m3 respectively, and the maximum sediment concentration is 0.12 kg/m3; the sediment concentration is inclined to increase with the powerful tide.

The research provides the basis for fine evaluation of complex lithology profile by using the well logging data.
The numerical reading of compensated neutron logging is the response of the content of hydrogen which is the main reduction material in rock, the difference between mineral component shows different character of neutrons reduction.

So, the data size of the spectrum can be reduced by the ICA.
The principle of ICA ICA is a new data analysis tool.
In this paper, the FastICA algorithm is used to process the spectroscopic data.
It is determined by the principle that the detention of the data is lower and the nicety of grading is higher.
The spectroscopic data is converted to the two-dimension form from the EEM matrix form.
