We derive the general equations of motion for a braneworld containing a (localized) domain wall. Euclideanization gives the geometry for braneworld false vacuum decay. We explicitly derive these instantons and compute the amplitude for false vacuum decay. We also show how to construct a toy ekpyrotic instanton. Finally, we comment on braneworlds with a compact spatial direction and the adS soli...
This is a summary of the work in the author’s recent paper with this title written with Jerome Gauntlett, George Papadopoulos and Paul Townsend, hep-th/97022012. We showed how to construct hyper-Kähler 8metrics in terms of arrangements of three-dimensional hyperplanes in six-dimensional euclidean space. The slopes of the planes define two relatively prime integers (p, q). Under reduction to ten...
We study string theory on the analytically continued β deformed background proposed in hep-th/0509036. This non-static model provides a solvable conformal field theory which describes time-dependent twisted string dynamics. With the mini-superspace approach, we examine disk one-point correlators of D-branes and compute winding string pair production rate. We find that these results are consiste...
The existence of single-party systems in the world today, on the one hand, and the fact that federal governments in some parts of the world, meanwhile, make the two cases more contemplative. On the other hand, with the advent of both systems in Iraqi society, it is questioned how the interaction of a single-party system with federalism and what problems and challenges have arisen in this regard...
Successive changes in the Persian Gulf region after fall of the Shah In 1979, led invasion of Iraq to Iran. According to experts in International politics, Iraq’s attack is known as America’s proxy war against Iran with at least cost for its main party, America, and extensive damages for Iraq and Iran later. America's actions in the Iran-Iraq war caused to decrease credibility of United Nations...
acknowledgements i wish to express my gratitude to all those who have helped me in preparing this thesis. i would like to express my deep gratitude to my respected advisor dr. kourosh akef, whose advice and comments helped me in the early stages of the research and throughout the writing process. i would also like to express my gratitude to dr. hajar khanmohammad whose invaluable guidance he...
increasing academic and professional language demands around the world are not a deniable fact. the purpose of this study was to investigate english language needs and communication needs of the chemistry students at master and ph.d. levels at the iranian universities. in this research, different methods were used including un-structured interview, structured interview, and two sets of question...
BACKGROUND Military fatalities occur in clusters, and causes differ between theatres of operation or within-theatre over time. AIM Based on around 500 coalition deaths, identify major causes in Iraq and Afghanistan. For consecutive periods (1: May 1 to September 17, 2006, 2: September 18, 2006 to February 4, 2007), ascertain UK and others' numbers deployed to compare fatality rates per 1000-p...
