Many methods have been proposed for the isolation of temporarily suppressed phases of diphasic Salmonella (Craigie, 1931; Gard, 1938; Hajna, 1944). These absorption methods are effective but require incubation for at least two days and considerable manual labor. Juenker (1946) suggested a procedure by which broth was inoculated with the organisms of the desired phase by passing them through a s...

The male drumming call of Isoperla nevada is described for the first time. The call is composed of a variable number (mode = 3) of diphasic sequences. The first sequence is longer, and contains more beats than the following ones. The number of beats per second increases during phase I of each sequence. The time between phases is less than 0.03 seconds while the time between two sequences varies...

Strains of most Salmonella serovars produce either one (monophasic) or two (diphasic) antigenic forms of flagellin protein, but strains capable of expressing three or more serologically distinct flagellins ("complex" serovars) have occasionally been reported. A molecular genetic analysis of a triphasic strain of the normally diphasic serovar Salmonella rubislaw revealed that it has three flagel...

Northey, W. T. (Arizona State University, Tempe) and L. D. Brooks. In vitro conversion of Histoplasma capsulatum. J. Bacteriol. 84:577-580. 1962.-The in vitro fungus-yeast conversion of the diphasic fungus, Histoplasma capsulatum, has been accomplished using enzymatic digests of casein. Of these casein digests, the most rapid and complete conversion was found when Ferm-Amine Types I, II, and II...

Abstract The aim of this study was to describe the growth curve “Aurora 1” peaches using fruit height and diameter data over time through diphasic sigmoidal models constructed from eight combinations following models: Brody, Gompertz Logistic. Data were obtained an experiment carried out in 2005 municipality Vista Alegre do Alto, São Paulo, Brazil. parameters adjusted by least squares method Ga...

The invertible deoxyribonucleic acid (DNA) segment cloned from Salmonella sp. was radioactively labeled and used as a probe to search for homologous sequences by Southern hybridization. Only one copy of the invertible segment could be found on the Salmonella sp. genome. Partial sequence homology with the invertible region was detected in bacteriophage Mu and P1 DNA by low-stringency hybridizati...

This paper presents a comparison of three programming models—OpenMP, HPF, and MPI—applied to a diphasic compressible fluid mechanics code. The parallelization analysis is conducted, and the authors also present the experimental results obtained on various platforms: a Compaq Proliant 6000 (4 processors), a Cray T3E-750 (300 processors), an HP Class V (16 processors), a SGI Origin 2000 (32 proce...
