High temperature superconductors with a nominal composition HgBa2Ca2Cu3O8+δ
for different values of pressure (0.2,0.3, 0.5, 0.6, 0.9, 1.0 & 1.1)GPa were prepared by
a solid state reaction method. It has been found that the samples were semiconductor
P=0.2GPa.while the behavior of the other samples are superconductor in the rang
(80-300) K. Also the transition temperature Tc=143K is the maximum at P is equal to
0.5GPa. X-ray diffraction showed a tetragonal structure with the decreasing of the
lattice constant c with the increasing of the pressure. Also we found an increasing of
the density with the pressure.
The study focused on the identification of the natural relation between the organizational components, and the most important is the organizational structure, which not hid its effect on each function and operation of the organizational structure through commanding the individual craters and its forms according to the requirement of these function, also it has relation with an organic synthesis that between the dimensions of the organic synthesis and the practice side in the commission of Integrity.

Sports and legend rooted deep in human history, and although they meet in the oldest epics as was the hero Gilgamesh legend and a hero of the heroes of wrestling has been named the oldest regular sports tournament in history in his name, a Algeljamchih Games which will be held events in Mesopotamia in August of each year and will continue nine days and take place in competitions in more than a sports game ..

In this context, a move sports media for the production of myths we studied Semiaiaa in an effort to learn how the production proce
لم تعد ظاهرة غسل الأموال ظاهرةً محلیة أو إقلیمیة، فكل دولة معرضة لهذه الظاهرة لانتأثیراتها تستهدف الإنسان أینما كان باستهدافها الأوضاع الاقتصادیة والمالیة والاجتماعیة وحتىالأخلاقیة، سواء على المستوى الوطني أم على المستوي الدولي، فضلاً عن استغلال الاندماج الحاصلفي أسواق المال الدولیة والتطور التقني في الأنظمة المالیة لنقل الأموال المراد غسلها وتحریكها إلى إيمكان في العالم، وهو ما
Nathaniel Hawthorne is famous for his psychological and moral themes. He is also famous for using symbolism in presenting his poignant themes of sin and its consequences. This research paper studies the use of symbols in Hawthorne's The House of Seven gables as an example of his general use of symbolism in his novels. The general pattern of Hawthorne's symbolism is that he presents one major symbol that embodies the main idea, and supports it with a number of minor symbols that develop and elucidate it. In The House of the Seven Gables, the major symbol is the house itself, which stands for corruption, evil, and the injustice of the past. This symbol is supported by such secondary symbols as the heart, the fountain, the
