Using the NORSTAR riometer and CANOPUS magnetometer arrays we have investigated the modulation of high energy electron precipitation by ULF waves in the Pc5 frequency band. We conducted two separate studies of Pc5 activity in the riometers. The first is an independent survey of three riometer stations in the Churchill line (one at each subauroral, auroral, and typical polar cap boundary latitud...

Stanhopea tigrina is a Mexican endemic orchid reported as a threatened species. The naturally occurring microorganisms present in S. tigrina are unknown. In this work, we analyzed the diversity of endophytic and epiphytic culturable fungi in S. tigrina according to morphological and molecular identification. Using this combined approach, in this study we retrieved a total of 634 fungal isolates...

In this paper we consider a model where malicious agents can corrupt hosts and move around in a network of processors. We consider a family of mobile-fault models MF(t n?1 ;). In MF(t n?1 ;) there are a total of n processors, the maximum number of mobile faults is t, and their roaming pace is (for example, = 3 means that it takes an agent at least 3 rounds to \hop" to the next host). We study i...

Note. In the past decade, the career of Dr. D. Ewen Cameron (1901-67), particularly his work at McGill in the 1950s and early 1960s, has attracted much attention. At least three books have been published about Cameron's controversial practices,' now thoroughly discredited, of using various so-called depatterning techniques, including LSD, in investigating schizophrenia and in attempting to trea...
