Center of Rigidity and Center of Shear in Wall-Frame Systems

In case of torsion in buildings, additional earthquake forces affect the structure and internal forces and displacements increases.For this reason, it is important to place the bearing systems in the plan as much as possible to reduce the torsion effect.To minimize torsion effects, the center of mass and center of rigidity should be as close as pos

Palynological analysis of the Late-Holocene vegetation and climate of Ganli-Gol wetland near Urmia, northwestern Iran

Palynologial analysis of a core from Ganli-Gol wetland reveals the Late-Holocene vegetation dynamics and the role of climate and man on the past environment in northwestern Iran.Our pollen diagram shows substantial changes in vegetation over the period 3000-1600cal.BP.Artemisia and/or Chenopodiaceae must have abundantly contributed in the vegetatio

Unidirectional Reflectionless Propagation in Plasmonic Waveguide System Based on Phase Coupling Between Two Stub Resonators

A scheme on unidirectional reflectionless propagation is theoretically investigated in a plasmonic waveguide system which consists of two metal-insulator-metal (MIM) stub resonators side coupled to an HERBAMARE SODIUM FREE MIM plasmonic waveguide.By appropriately tuning the phase difference between two stub resonators, unidirectional reflectionless
