We present the properties of 105 events of the form e + + e-~ e ± + ~t; + missing energy, in which no other charged particles or photons are detected. The simplest hypothesis compatible With all the data is that these events come from the production of a pair of heavy leptons, the mass of the lepton being in the range 1.6 to 2.0 GeV/c 2 In a prev!ous letter(More)
Polycyclic aromatic hydrocarbons (PAHs) are semivolatile organic compounds (SVOCs) categorized as persistent organic pollutants (POPs). PAHs are ubiquitous in terrestrial, atmospheric, and particularly aquatic environments throughout the world and have been detected in lakes, ground waters, and rivers. This research work involved the analysis of five PAHs,(More)
