The temporal diffraction field function is related to the width of the laser pulse, the structure of the serrated aperture, the Fresnel number at central frequency and time.
Introduction The femtosecond laser technology has been used in many fields such as in material manufacturing process and medicinal treatment, chemistry, biology, and micromachining.

The nuclear structure factors FN(Q) can be calculated from the known crystal structure.
Such studies have played a prominent role in solid state physics, chemistry and materials science in recent years.
The structure described by model 1 is the correct arrangement of atoms in the Heusler L21 structure.
It is less than for pure physics (38 %) and considerable more than for chemistry (16 %).
In the organic chemistry and biology, the possibility of isotopic substitution can be exploited in elucidating the precise location of hydrogen atoms for example in biopolymers.

Introduction Silk I, silk II, and silk III are the suggested structures of fibroin [1-3].
There are also three silk fibroin secondary structures; a random structure, an α-structure in absence of shear force, and a β-structure induced under shear force or action of solvents, such as methanol [4,5] Table 1 shows B.mori fibroin conformations within FTIR amide absorption bands, and their vibrations.
Table 1 Amide wave numbers and protein secondary structure [11-17].
Compared to DS and SFLiBr, this was a strong shift towards a random coil structure.

These problems were solved by changing the water chemistry treatment method.
This effect can be expected by the change of structure in this temperature.
In the result of SCC susceptibility according to the temperature, we can know that the material structure is more affected by high temperature.

In this structure, some regions can be observed which are called domains.
This method is based on the fact that a highly ordered texture has periodic structure.

As with radiography, access to both sides of the structure is required.
The gamma transmission tomography system is divided into three mainthree main parts: 1) Mechanical structure 2) Communication for data transfer 3) Computer for data logging and image reconstruction Fig.2 Arrangement of system components for projection taken at 0° Fig.2 shows that the source and detector are positioned at opposite ends of the specimen and then are moved simultaneously using stepper motors.

The XRD pattern shows a formation of nano structured Fe3O4 with FCC crystal structure.

This structure has grate similarity of the process of 1/f [6,7].
These multiscale slope features make a convenient estimate of the signal structure which depends on the rotating machinery working conditions.

The structure of the final products was examined by X-ray powder diffraction (XRD) using Cu Kαradiation on RIGAKU D/max 2200 vpc X-Ray Diffractometer.
This result shows that these phosphors doped different content Eu2+ are still of the same monoclinic structure as SrAl2Si2O8, and no other phase was observed in these patterns.
