For the JCPDS file number 01-075-2230, and 00-040-1516 corresponds to calcite and chitosan phase, respectively.
While, the morphologies of the eggshells is seen that the ES-PD samples have the porous scattered all over samples and the pattern like stack of lamella foliated and disoriented foliated grains Fig. 3.

Introduction
The occurrence of yttrium and lanthanide oxynitride glasses as grain boundary phases in silicon
nitride based ceramics and the desire to understand their nature has resulted in a number of
investigations on oxynitride glass formation and properties [1-7].

Besides, the aim was to obtain crystals with a cylindrical shape and flat top
surface to minimize the number of low grain boundaries.

Results and discussions
A number of facets were observed on as-grown crystal surfaces resulting from the first set of
experiments, Fig. 1a.
Grains from the neighboring polycrystalline rim transmit their polytype information into the central monocrystalline area along the c-axis.

The dump
material is mainly fine grained due to former coal washing processes, and has an enhanced water
permeability.
In particular, the drainage ditch contained large numbers of iron- and sulfate-reducers.

And this system could directly be used for data storage module in grain yield measurement system if it modified.
So it is easy to change rotate speed only by changing the number of pulses of stepper motor output.
Therefore, fertilization shaft rotate speed calculation formula is: (4) Where, n is the fertilizer shaft rotate speed (rpm); m is the number of pulses (pulses/s); s is micro-stepping numbers; x is the reducer transmission ratio.
When the fertilizer needs of farmland districts are determined, the number of the outputted farm machinery moving speed adjustment pulse supplied by speed sensor accommodates the fertilization rate.
Experiment Process and Results Inputed field number 0 and needed fertilization rate (N: 30g, P: 20g; K: 15g) to control system input interface by the matrix keyboard (Fig.2).

The linear converging die
is having some specific advantage over the flat faced die in respect of low friction, less redundant
work and more uniform grain structure [10,11,12].
Therefore the total number of unknown velocity components in the global level becomes 3N+1.
All these unknown velocity components can be uniquely determined if an equal number of equations are generated.
Hence, it results in ten tetrahedrons, with the number of global schemes of discretisation being four.
