By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...

landslides and slope instabilities are major hazards for human activities often causing economiclosses and property damages. sikan river basin (ilam province) due to the topography, tectonic,lithology, and climate has enough potential for occurrence of this phenomenon. the objectives of thisstudy were to determine effective parameters controlling the landslide occurrence and to preparezonation ...

The knowledge of the surface topography has a major importance in the field of Earth sciences. It is essential in any discipline concerned with process modeling like hydrology, climatology, geomorphology and ecology. The present study utilized Environmental Systems Research Institute’s (ESRI) ArcGIS 9.3 (with the spatial analyst extension) software, remote sensing data ( DEM and Digital Aerial ...

For heavy-ion synchrotrons an efficient multi-turn injection (MTI) from the injector linac is crucial in order to reach the specified currents using the available machine acceptance. The beam loss during the MTI must not exceed the limits determined by machine protection and vacuum requirements. Especially for low energy and intermediate charge state ions, the beam loss can cause a degradation ...

We present a comprehensive analysis of the Non-Minimal Supersymmetric Standard Model (NMSSM) for large values of tanβ, the ratio of the vacuum expectation values of the two Higgs doublets, which arise when we impose the constraint of the unification of Yukawa couplings in the model. In this limit we show that the vacuum expectation value of the singlet is forced to be large, of the order of 10 ...
