The refinement of the microstructure and reduction of the volume fraction of the η phase up to 1.7%, as compared to 4% in the mould cast alloys was observed in the ribbons.
According to the data presented in [9], the maximum extension of a solid solubility by rapid solidification could increase up to 1.5 at. % while the maximum equilibrium solid solubility is 0.083 at. %.
Peak positions for the η phase were shifted towards higher 2Θ angles, as compared to the catalogue data for MgZn2 phase.
The microstructure refinement and reduction of the volume fraction of the η phase up to 1.7% (as compared to 4% in the mould cast alloys) as well as the increase the amount of the solute Mg, Zn and Cu occurred in the matrix of the analyzed ribbons.

Measurement data is acquired and subsequently transmitted to PC via Host Link protocol.
Attention has been paid to the assignment of PLC data memory.
By careful data memory assignment, fast and reliable data transfer can be accomplished using standard baud rate, which meets the testing requirement with added practicality and efficiency.
The rotation type can be accomplished by a motor and a gear reduction mechanism.
By applying a background data measurement thread and careful assignment of PLC data memory, an improved program performance in speed has been accomplished.

The kinetic reviewed here was the relationship between glucose production and cellulose mass reduction to optimize the parameters of Monod equation at various moisture levels.
Results and Discussion Data obtained from the research were substrate concentration versus time and glucose concentration versus time.
From the experiments, the data for initial X and ψ were obtained, 0.52 g/L and 0.25 respectively.

It is important to include practical forged material data and frictional models to enhance the credibility of present simulator.
Figures 2 Ring compression test setup Figures 3 60 ton hydraulic pump The results were plotted in a graph of reduction of inner diameter against reduction of height as an “experimental friction calibration curve”.
In the future, a quick identification system using a special set tool-set for ring compression experiment will be developed to obtain specimen data of material deforming behaviours at different temperatures and strain-rates to improve the ring compression system.
Acknowledgement The authors would like to thanks Lee Wai Kit and Richard Wong King Sung, graduates of mechanical engineering, UTAR for helping the authors in collecting the experiment data.

The spectrophotometric data provide a description of the kinetics and the thermodynamics of the dye sorption process and the electrokinetic data provide information about the nature of the interaction.
The electrokinetic data provide information about the nature of the interaction.
The reduction of both types of diffusion coefficients due to the presence of KCl is obvious in the case of AR151.
Some responsibility for the reduction of dye concentrations on polymer may also be due to the increased aggregation of acid azo dyes in the electrolyte solution as already shown by a group of authors [9,10,11,12].

Modeling the price of CO2 emission allowances Obviously, over a whole commitment period of the emission reduction, the price of CO2 emission allowances will be fluctuating dynamically.
However, the bidding coefficients of rivals could be estimated based on historical data, load forecast and other available information, as stated in [4].
It should be stated here that in some operating electricity markets such as California, historical bidding data of Gencos are not broadcast in the market, however, in some other electricity markets such as those in China, historical bidding data are indeed available to all market participants.

The load test data and results see table 1, and the load test curves see Fig.1, then the relationship scatter diagram of the pile length and single pile bearing capacity see Fig. 2.
Test data analysis In Fig.1, the curves have no obvious inflection points.
Load[kN] ⑨ ④ ① ② ③ ⑤ ⑥ ⑧ ⑦ Settlement [kPa] Fig.1 Loading test curve of each pile Fig.2 Scatter plot of the relationship between the pile capacity and its length single pile bearing capacity [kPa] pile length[m] The calculation of single pile bearing capacity uses the following two formula, and take the little value as the design value [1,2]: Rp=η·qu·Ap (1) Rp=f·π·D·L+α·Ap·Rsb (2) RP, Rsb are the soil bearing capacity of single pile and pile endpoint; D is dry jet mixing pile diameter; AP is cross-sectional area; qu is unconfined compressive strength of cement soil; f is average friction of pile side soil; η is strength reduction factor of pile body, which is between 0.35 to 0.50; a is reduction coefficient of bearing capacity of pile endpoint soil, a = 0.5.
By contrasting data in table 1, the single pile length of test piles do not exceed effective length.

The creation of a free surface and broken symmetry leads to significant reduction of the total forces affecting atomic vibrations, both normal and parallel to the surface.
Therefore, the existing experimental data (Low Energy Electron Diffraction, Thermal Energy Atom Scattering, X-Ray diffraction) for sDT and DT can be applied directly to evaluation of heat capacity.
As a result of broken symmetry and significant reduction of the local forces, the atomic vibrations of surface atoms are strongly affected.
Being extracted form existing diffraction data, this ratio allows evaluation of the surface layer contribution.
The suggested model opens up a way to predict the heat capacity of nanocomposite materials directly from accessible experimental data for surface, sDT , and bulk, DT , Debye temperatures.

Dispersions were synthesized by the reduction of the molybdate and tungstate ions, using ascorbic acid as a reducing agent.
In accordance with the literature data, the presence of absorption in this region indicates the presence in the system of polyoxometalate complexes belonging to the {Mo154-x} family [7].
This range of pH values was selected based on the results of our previous studies and literature data [2,3].
As can be seen from the presented data, the dependences of the ζ potential on the pH value for systems with different molar ratios (Mo) :( W) are very close.

The presence of air bubble in the mixture may affect the data during compression testings.
The investigation shows that an increased in temperatures resulted in significant reduction of the compressive strength and modulus elasticity of the nanoclay filled polyester resin.
All weight percentage filler samples showed reduction close to 70% in strength, particularly at high temperatures closer to the Tg temperature.
Despite the reduction, the nanoclay filled samples have indicates improvement in strength by almost 40% from neat samples to 5wt% samples at elevated temperatures.
