We compare CO’s response to electric fields at edge and terrace sites on the stepped Pt~335! surface. The comparison is made at zero frequency and at the frequency of the C–O stretch vibration. Atop-bonded CO is observed with reflection–absorption ir spectroscopy ~RAIRS!, electroreflectance vibrational spectroscopy ~EVS!, and high-resolution electron energy loss spectroscopy ~HREELS!. Coadsorbe...

A study using plasma port single-pulsed discharge is performed on the flow control of asymmetrical vortices over slender conical forebody. The different circumferential steady and unsteady pressure distributions are measured in the wind tunnel test. At the same time, the local side force, the increment of local side force and the overall side force and moment are calculated with the circumferen...

  following cesarean infection is one of the main complications,and antibiotic prophylaxy is an important protective factor in reduction of postoperational infection.the aim of this study is to compare the prophylactic effect of single dose ampicillin to triple dose ampicillin following the operation.this prospective randomized clinical trial a total of 242 women were prophylactically treated ...

We study the radar cross section (RCS) property of an aircraft considering electromagnetic (EM) characteristics a frequency selective surface (FSS) radome, mounted on aircraft. Instead full-wave methods, we utilize high-frequency such as shooting and bouncing rays (SBR), physical theory diffraction (PTD), flat model, taking significant computational efficiency. Based developed algorithm, analyz...
