Combined electrospray ionization source with a velocity map imaging spectrometer for studying large gas phase molecular ions.

We present a new compact and versatile experimental set-up that has been designed to perform electron and ion imaging experiments on large multiply charged gas phase molecular and cluster species. It combines an electrospray ionization source, a quadrupole mass filter guiding ion optics and a velocity map imaging spectrometer. Characterization of the spectrometer has been performed on atomic ions. Results obtained on molecular species (stilbene 420 dianions) demonstrate the possibility offered by this experimental set-up.

Toward the integration of psychosocial services in the general hospital. The human services department.

This article describes an innovative administrative organization for the delivery of psychologic care in the contemporary teaching hospital that, by combining services under medical leadership, takes an evolutionary beyond multidisciplinary team approaches. The long-range goal of this organization is to provide cost-effective psychosocial services in the general hospital while maintaining the unique role contributions of the participating disciplines. To allow for informed decision making in this process, the initial step has been to establish a collaborative data base for patient and staff tracking, program planning, and evaluation.
