The possibility of searching in high energy e+ecollisions for a singly produced heavy lepton with an ordinary light lepton e+e+ L+t?, has been investigated. The search is motivated mainly by its distinctive experimental signatures. In a data sample corresponding to an inte grated luminosity of 30 fb-’ collected at a 1 TeV e+ecollider, the search is sensitive to a lepton of mass up to about 1 Te...

A controlled study using a sand-tank system was conducted to evaluate 10 forage species (bermudagrass, ‘Salado’ and ‘SW 9720’ alfalfa, ‘Duncan’ and ‘Polo’ Paspalum, ‘big’ and ‘narrow leaf’ trefoil, kikuyugrass, Jose tall wheatgrass, and alkali sacaton). Forages were irrigated with sodium-sulfate dominated synthetic drainage waters with an electrical conductivity of either 15 or 25 dS/m. Forage ...

Turfgrass selections including 21 paspalums (Paspalum vaginatum Swartz) and 12 zoysiagrasses (Zoysia sp.) were compared with susceptible ‘KY31’ tall fescue (Festuca arundinacea Schreb.) and more resistant common bermudagrass (Cynodon dactylon Pers.) and common centipedegrass [Eremochloa ophiuroides (Munro.) Hack] for potential resistance to fall armyworm [Spodoptera frugiperda (J.E. Smith)], an...

In the present work the presence of Paspalum notatum Flüggé (Poaceae) in Italy was reported for the fi rst time. It is a neophyte native to America, known for applications in phytoremediation. Its typifi cation, ecology and invasiveness status are also presented.
