WHERE K IS THE NUMBER OF VARIABLES AND Α IS 1.6879.
It indicated that during the initial phase leaching, the mineral grains exposed at the surface of the particles are leached at a fast rate.

Materials and Methods The samples of YBCO and YBCO + carbon nanotubes "Taunite", on which the results given in this work were obtained, were sintered compressions of fine-grained powders prepared by the method of solid-phase reactions.
Based on the data, it is difficult to assess the correlation between the number of magnetic and superconducting phases in the sample, which may be due to the different stoichiometry obtained during the synthesis and storage of the sample.

The presence of cobalt in the Ni-P matrix, independent on the method of introduction, changes the heterogeneity of the surface and increases the number of interfaces between nickel and cobalt.
This coating has a mat, rough metallic surface with visible grains of incorporated powder (Fig. 1c).

Bracket set is the element that combined by a number of Dou and Gong stacked each other, generally called “Puzuo” or “Section”.
After pouring, strickle the surface and vibrate on the vibration table in order to remove air bubbles and make the gypsum concrete symmetrical and close-grained.

(t0-toff-td) (1) where m is the erosion rate in grain per second Tm, L and Ts are melting point, latent heat of melting and superheat of eroded material respectively and Cp is the specific heat. f, Vs. and I are the frequency, sparking voltage and average current and to, ton, toff and td are respectively pulse time, pulse on time, pulse off time and ignition delay.
The number of pulses resulting in effective erosion are thus reduced by ineffective pulses from open circuit, short circuit and arcing pulses.

Wax pattern is dipped inside the slurry and placed under the rain fall of the coarse grained refractory stucco and dried.
To equate this there will be less number of coats required for camphor and needle coke and it will reduce the production cost and time in the industries.Camhor and needle coke have resulted pores inside the ceramic shell after firing while to full fused silica shell has neglegible pores inside.

Samples for LM observations were prepared by conventional grinding with waterproof sandpaper of grain size up to 4000 and subsequent mechanical polishing on diamond polishing paper 1, 0.5 and 0.1mm (Buehler, U.S.A.).
The cumulative probability F(Rn,i) for each Rn,i value obtained during 24 hours period of measurements was determined as follows: first, Rn,i data were ascendingly sorted and then F(Rn,i) values were calculated as i/(N+1) where i is the rank in sorted Rn data and N is a total number of Rn data points [13].

The slugs were cut and held at 600 ± 50 C for 20 min to allow the spheroidization of the grains.
The size of primary silicon particles reduced 53% and the number increased 76% compared with that of the as-cast sample.
