A random laser is a non-conventional laser whose feedback mechanism is based on dissorder-induced light. However, random lasers occur in gain media with numerous scatterers and produce coherent laser emission without any predesigned cavity. The generation of coherent emission from multiple scattering is quite general and its basic principles are shown here using sulforhodamine B-TiO suspensions system. These suspensions were pumped with 337.1 nm pulses from N2 laser and the spectral and temporal behavior of light emitted from the pumped surface was recorded. When we pump power above a certain threshold a dramatic narrowing of the emission line width and a shortening of the emitted pulses were observed. We have experimentally found that in a random laser based scattering, the threshold pumping density decreases with pump energy increased.
The letters draw clear picture for what had happened in that time it was full of incidents .that incidents had began with the byzantine invation and persioan persecution .later on the Muslins managed to conquest Iraq and Persia .the muslims spread peace and security for the pupils of that area.

This diversity in communities make individuals differ acconding to the following:

По мнению ученых, исследующих современные деривационные процессы, „начиная со второй половины XX в., активизируются новые социолингвистические и коммуникативные факторы”, определяющие специфику современного словотворчества в ряде типологически близких славянских языков [Нещименко 2010: 39]. В результате возросшего влияния масс-медиа на коллективное сознание носителей языка, на существующий вербальный
