    Notes: Abstract Residual activities produced via35Cl or32S beams in thin112Sn and106Cd targets have been studied by γ-ray and X-ray spectroscopy techniques behind a He-jet system. Mass identification of the products has been performed by coupling the He-jet to the medium current ion source of an isotope separator. Neutron-deficient nuclei with 137≦A≦144 have been identified. Decay schemes of several new isotopes as138Eu (12s),141Gd (22s),143Tb (12s and 〈17s),144Dy (9s) and possibly140Gd (11s) have been derived. New informations have also been provided for137Sm (45s),139Eu (24s) and144Tb (5s). Data have been presented through systematics. The shapes of these nuclei and their trends versusN andZ have been analysed.

    Description: A new method for dispersing of warm fogs which impede visibility and alter schedules is described. The method uses large volume recycled water sprays to create curtains of falling drops through which the fog is processed by the ambient wind and spray-induced air flow; the fog droplets are removed by coalescence/rainout. The efficiency of this fog droplet removal process depends on the size spectra of the spray drops and optimum spray drop size is calculated as between 0.3-1.0 mm in diameter. Water spray tests were conducted in order to determine the drop size spectra and temperature response of sprays produced by commercially available fire-fighting nozzles, and nozzle array tests were utilized to study air flow patterns and the thermal properties of the overall system. The initial test data reveal that the fog-dispersal procedure is effective.
