Singh et al [3] have determined that the use of high-thermal conductive nanofluids in radiators can lead to a reduction in the frontal area of the radiator by up to 10%.
This reduction in aerodynamic drag can lead to a fuel saving of up to 5%.
Also comparison with various data by Wang & Mujumdar [11] indicates that the thermal conductivity of nanofluids increases with decreasing particles size.

Introduction
The silicon metal or the industrial silicon is the product with more than 97% of silicon obtained from the carbothermic reduction reaction between the silica and the charcoal (or other carbon reduction agent) at about 2000 degrees of temperature, which mainly used in silicon-aluminum alloy, semiconductor materials and organic silicon and many other areas.
As Figure 1 shows, the PLC control program includes the parameter initialization, the chamber cleaning, the motor start/stop module, the circuit fault detection, the zero speed diagnosis, the power control, the data transmission, and so on.

Methods for enhancing combustion efficiency include reduction of cooling loss and pumping loss, increase in compression ratio, and effective ignition [6].
To conduct each experiment, Pressure Sensor, MFC (Mass Flow Controller), Chamber, DAQ (Data Acquisition), etc. were composed in order to ensure experimental accuracy and to construct specific environment.
Maximum reduction ratio occured by 13% at arc type.
Since each type shows differences in the point where maximum combustion pressure occurs, additional studies may be used as fundamental data for new combustion ignition techniques.

At present, although the technology of selective catalytic reduction (SCR) for reducing nitrogen oxide
has already been put to practical use, one primary disadvantage of this technology is that it requires
addition of reductants such as hydrocarbons, CO or NH3, which can lead to production of secondary
pollutants.
Especially at higher temperatures, CeO2 tends to be sintered, resulting in a reduction in oxygen storage capacity.
Powder X-ray diffraction(XRD) data were obtained from an X-ray diffractometer (type D/MAX-1200, Rigaku) operated at 40 kV and 30mA at room temperature, using Cu Kα radiation combined with nickel filter.
TG analysis data were obtained from thermal gravimetric analyzer (type TGA-50, Shimadzu) operated at nitrogen flow rate of 20ml/min, heating rate of 10℃/min.

It is interesting to note that the data can be
classified into two groups depending on the
grain boundary character distribution.
In particular, an approximately 50% reduction in fracture stress was observed in Mg-doped SiC.
Accordingly, intergranular degradation was responsible for severe strength reduction in Mg-doped SiC.
The data in Fig. 6 can be classified into two groups depending on the grain size.

These two methods need original rocks and their corresponding altered rocks’ chemical analysis data, but Gresens method also need the specific gravity of rock, while Grant method not and it avoids complicated processing of data.

Fanshtejn researches [22] the data about influence of an external magnetic field on decrease energy of stacking fault are contain.
But the lower is temperature, the less is formed stress-assisted martensite because of reduction of austenite plasticity.
These results are confirmed by aforementioned data about reduction of amount residual austenite after hardening in a magnetic field.

As a result, the data of the residential living environment including productivity, energy consumption and other information could be displayed directly in real time.
Therefore, the data of residential capacity, energy consumption and environment can be displayed on the screen and presented though 3G mobile phones.
This will help to promote the technology development, as well as progression of energy conservation and emissions reduction [6].
Products can be understood visually, and thus enhances the initiative of green consumption, energy conservation and emission reduction, the concept of sustainable development.

Capillary water absorption of mortars was measured according to DIN 52 617 to assess water uptake reduction upon powder addition.
Addition of Powder SHA, SHB and SHC in mortar composition leads to a very significant reduction of water uptake.
Discussion This set of data illustrates the excellent durability of silane-based integral water repellent treatment.
This set of data shows that the “integral hydrophobic treatment” induced by the addition of silane-based powder is not impacted by UV radiation or by sun/rain cycles.

For manufacturing of firmly bonded ceramic joints via glass solder, a portion of the samples was joined using a high temperature oxide furnace (Nabertherm) in air atmosphere.
Precise data on geometry and base material are given in table 2.
For both considered laser joints, heat treatment is presumed to be responsible for dumping inner stresses leading to reduction of strength scattering.
A major strength reduction was observed due to large pores or pore fields (nonsufficient joining), whereas higher strength was found for minimum pore proportion.
