Results of the trials showed substantial reduction of micro-porosity defect in crankshaft (casting).
Outcome of the trials the results showed substantial reduction in rejection due to micro-porosity defect in crankshaft as shown in Figure 6.
Result of the trials for the two months showed substantial reduction of micro-porosity defect in crankshaft (casting) from 43.4 % in August 2013 to 6.0 % in October 2013 as shown in Figure 6.
Therefore, this reduction of the defect will save cost of around RM60K per month as shown in Figure 7.

Halogen FR is known for its low cost, miscibility, processability and low reduction in physical/mechanical features of systems.
Only registered FR chemicals with hazard data that underwent various tests concerning emissions and possible end-of-life issues can be used [7].
The data acquired clearly show a synergistic effect between phosphorus and nitrogen in the FR system.
The statistical data from the annual report of China’s comprehensive resource utilisation by the National Development and Reform Commission indicate that the total generation of fly ash was 540 million tonnes in 2011 and the comprehensive utilisation was at 67.9% or 367 million tonnes.
The data presented indicate that the production of CCP products will steadily increase annually and the utilisation of FA is predicted to increase as well.

The data were analyzed using 1-way ANOVA and t-test.
X= 1+vlnBC2+1-v2BC2 (2) Y= 1+vlnAC2+1-v2AC2 The data obtained from the results of this study were tested statistically by statistical tests ANOVA and t-test.
The subtraction in the mean biaxial flexural strength of the reglazing groups may be due to the reduction in surface depth.
Sandhu [30] reported that the depth of surface reduction and fracture caused by grinding can exceed the depth of the compressive surface layer resulting in specimen failure.
Occlusal adjustments should be using fine diamond burs or grinding under water cooling to prevent a reduction in the mechanical properties of zirconia.

Over time, the diffusion potential decreases due to a reduction in the carbon atom concentration gradient.
Constants in the equation (8) are as follows[8]: S0=30.593ppm; D0=2×10-6m2/s; Ea=84100 J/mol; Es=100018 J/mol; R=8.315 J/mol K; dc-c=1.44×10-10m From experiment data and the Fig. 3, the relationship between the diameters is: (9) Graph of CNTs’ growth rate and growth temperature can be obtained with above data and equation(8).

By spectrophotometric analysis it was possible to observe a significant reduction in oil concentration in the permeate for the Y zeolite membrane / alpha-alumina, thus showing that they have the potential for this application.
Characterization X-Ray Diffraction (XRD) - The data were collected from samples using the powder method employing a Shimadzu XRD-6000 diffractometer with CuKα radiation, voltage 40 kV, current of 30 mA, step size of 0.020 2θ and time per step of 1.000 s, with a scan rate of 2 °(2θ)/min with 2θ angle traversed from 0º to 50º.
From the data, presented in Fig. 3, it is possible to observe a decrease of 91.84% in the concentration of the permeate in the first 10 minutes of filtration 93.24% in 20 minutes, it remained virtually constant until the 40 minute filtration, taking into account the initial concentration .

Material balance and fractional composition of liquid products cracking and reduction of sulfur containing in every component of it was established.
Resins 4.24 0.22 Asphaltenes 1.97 Trace amounts Distillate fractions content in initial gasoil and in cracking products was estimated based on data of thermogravimetric analysis.
Resins and asphaltenes, which were extracted from initial and after thermolysis heavy HC raw material, were developed by means of structural-group analysis (SGA) using method developed in the IPC SB RAS and based on compounding the results of elemental composition, average molecular weights and PMR spectrometry data.
The most deep resins molecules destruction occurs after vacuum gasoil oxidation pretreatment by PB and results in resins MW decrease (227 a. m. u.) at the same time significant reduction in the total rings number up to 2, almost entirely absent sulfur atoms (on average 0.14 atoms per molecule), in turn molecular aromatic factor increases to 77.99.

PCA (Principal Components Analysis) can simplify the data processing on the basis of the maximum retention of information of the original data, thus highlighting the useful signal.
The main idea of KPCA is that map the data of the sample space into a new high-dimensional feature space by the nonlinear function; Then, PCA is used to this kind of mapping data, and obtain the principal components of the original sample data.

The data of basic research in the field allowed us to suggest methods for manufacturing new cast nickel aluminides based alloy.
The influence of overload may result in both reduction of the substance loss during combustion and more complete separation of the metallic and oxide phases.
According to XRD data, were not detected Cr, Mo-containing intermetallics, despite a high Cr and Mo content.
