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.

تعد المتابعة أحد العناصر الأساسية في الإدارة الرياضية، حيث تسهم في تحسين الأداء وتحقيق الأهداف المنشودة ويهدف هذا التقرير إلى تسليط الضوء على دور المتابعة واهميتها في سياق الرياضة.
Die vorliegende Forschung handelt es um die Satzfelder, besonders das Mittelfeld des Satzes im deutschen und Arabischen. Diese Forschung wurde mit der Satzdefinition, Satzglieder begonnen, damit wir diese klar werden und dann werden die Felder des Satzes gut gekannt. Der erste Abschnitt schlieβt auch den Mittelfeld des Satzes und, wie man das Feld erkennen und bestimmen kann. Die Forschung untersucht auch. Ob es in der arabischen Sprache den selben Struktur wie im Deutschen gibt, z.B Bildung des Satzes sowie Satzfelder bezügllich das Mittelfeld.
Der zweite Abschnitt handelt sich um den arabischen Teil und behandelt die Wortarten im Arabischen sowie den Satz als auch Satzarten (Nominal- Verbal- Halbsatz).

And because translation is important in many sectors in the society such as technology, science, popular institutions, tourism and political and legal relations between countries.
Our investigation concentrate on the articles of translation teaching in fourth class/ Spanish Department/ College of Languages/ Baghdad University for five years in order to evaluate the level of utility of creating translators and interpreters after graduation .
From 2009 until 2014 we saw continuous yearly exchanging in teaching articles by many professors with diff

This research aims to highlight the prophetic approach in civilized coexistence, and to show what society was like in the time of the Prophet, and specifically after the sakha and the writing of the newspaper (prophetic document) which established the rules of civilized coexistence, and there is no doubt that God almighty created all nations and different peoples according to Human nature, this difference has been recognized by the duty of coexistence and acquaintance without abolishing each other, coexistence and recognition of the other and respect for its particularities result in a state of dialogue between cultures and civilizations and paves the way for their meeting instead of clashing, as well as contributing coexistence to make
