Simultaneous photoproduction of eta and pi0 mesons on the proton.

The analysis of the gammap-->etapi(0)p reaction has been performed using data from the GRAAL experiment. The total and differential cross sections and the beam asymmetry have been obtained from threshold up to 1.5 GeV of beam energy.

Evidence for nucleon-resonance excitation in omega-meson photoproduction.

The photoproduction of the omega meson has been studied at GRAAL from threshold up to a photon energy of 1.5 GeV. The differential cross sections and beam asymmetries have been measured precisely at all angles.

Complications with outpatient angiography and interventional procedures.

Purpose: To prospectively identify the complications, and rates of complication, in outpatient angiography and interventional procedures.

Methods: There were 1050 consecutive patients, 646 men and 404 women, aged 17-89 years, with a total of 1239 procedures studied in a 2-year period, 1997 to 1999.

Results: There were 560 cases of aorto-femoral angiography, resulting in 124 complications (22%), with pain or hematoma in 110.
