Cryptosporidium and Giardia are two important pathogenic parasites that have caused many waterborne outbreaks which affected hundreds of thousands of people. Contamination from effluent discharged by sewage treatment plants have been implicated in previous waterborne outbreaks of Cryptosporidium and Giardia. This study evaluated the reduction of Cryptosporidium and Giardia (oo)cysts in two sewa...

IP 95-1 Page 1 This is the story of teacher trainees in the Los Angeles Unified School District (LAUSD) alternative training program during a labor dispute. The individual stories highlight the stress a labor dispute places on prospective teachers who are not yet full-time teachers but also not the traditional transitory student teachers from a university teacher education program. In the dispu...

We examine the power of Boolean functions with low L 1 norms in several settings. In large part of the recent literature, the degree of a polynomial which represents a Boolean function in some way was chosen to be the measure of the complexity of the Boolean function (see, e. have high degree, but small L 1 norms. So, in conjunction with communication complexity, instead of the degree, the L 1 ...

We continue our study of matrix models of dually weighted graphs. Among the attractive features of these models is the possibility to interpolate between ensembles of regular and random two-dimensional lattices, relevant for the study of the crossover from twodimensional flat space to two-dimensional quantum gravity. We further develop the formalism of large N character expansions. In particula...
