Many applications of zirocnia ceramics will involve a varying load and it is well known that in uniaxial creep a stress reduction can produce a period of zero creep before the new rate is established.
The gradient of three trend lines of the hardness data for each material analysed using least square method were within 5% difference.
It is well known that in uniaxial creep a stress reduction can produce a period of zero creep before the new rate is (a) Ce-TZP (b) YCPZ Fig. 4 Indentation creep of zirconia ceramics under constant (open symbols) and variable loading (filled symbols).

The ultimate goal of e-paper is to reduce the use of paper in everyday life, and to do so by using writable data on paper-like display devices.
In the current experiment, the reduction in the removal from the surface of the optical PET diaphragm after micro electroremoval for the Indium-tin-oxide (ITO) thin film coatings is 20 nm.
Compared with the experimental results, the small gap width r of 3mm accompanied by a large current rating and a fast feed rate of the workpiece (optical PET diaphragm) shows a reduction in the etching time and is found to be more effective in this study.

A significant reduction in crack width and crack spacing is possible, especially at early ages [7].
It was observed that bulk density of all samples increased up to 7.5% at 800 ºC whereas X-ray data showed (Fig. 3) formation of crystalline gehlenite (C2AS) phase through possible metakaolinite reaction with βC2S [11].
Due to crystalline phase transformation less shrinkage but further reduction of CCS was measured at 1000 ºC.

The development of minimum quantity lubrication with cooling air (MQL-CA) cutting technology and its extensive applications has promoted because of the requirement for the reduction associated with cutting fluids and the restrictions on the use of dry machining [4].
The system consists of a vertical machining center, a three component dynamometer, a charge amplifier, an 8-channel data recorder and a PC based software for online monitoring and recording of the cutting force.
With the application of MQL and cooling air(−10℃, −30℃, −50℃) in the cutting zone, there is a substantial reduction in the cutting force compared to wet cutting condition.

Last condition is most likely at a high tin content (Fig. 5b), and that is confirmed well by the data in Fig. 6, indicating that CM Al-Sn with the weight tin content of 40 ± 5% have the maximal wear resistance.
It occurs due to reduction in the intensity of deformation defects accumulation in the aluminum matrix, reduction of its work hardening and, thereof, damageability.

Increasing the concentration of reactants by lowering the amount of solvent, i.e. water, is a facile solution to compensate the temperature reduction [9].
It was succesfully shown that decreasing amount of water is able to compensate reduction in rates from lowering the temperature, as crystalline MFI phase was obtained.
On the basis of these data, it seems that lower temperature lead to more nuclei formation which crystallize into small crystals.

As a consequence of this and given the conflicting data available concerning the impact of Ca it was decided to perform a series of experiments in which ingots containing varying amounts of Ca and Na were cast and processed under controlled laboratory conditions.
After holding at a temperature of 510oC for two hours, the ingots were rolled to a 50% reduction.
Fig. 10 shows the impact of Ca on the as cast surface of three ingots clearly showing the reduction in drag marks and oxidation during casting.

Fig. 3 Absorption coefficient of H2O loading (equivalent to weight of polyols) of green polymer foam Fig. 4 Noise reduction coefficient (NRC) of green polymer foam with H2O loading (equivalent to weight of polyols) Furthermore, noise reduction coefficient (NRC) of the green polymer foam with different percentages of H2O on Fig. 4 where represent the amount of sound energy absorbed upon striking a particular surface.
However, where low or very high frequencies are involved, it is usually better to consider sound absorption coefficient instead of NRC data [15].

The overall deflections were automatically recorded by a MW100 YOKOGAWA data acquisition unit.
It is found that an increase in the eccentricity resulted in a pronounced reduction in the critical buckling moment of all L/d ratios.
In the same way, an increase in the eccentricity from 0 to -3e resulted in a reduction of 14.8-65.2% for the load applied in the negative direction of the x-axis.
