The observation of localized stationary structures, coined oscillons, in granular media has evoked much interest. By parametric excitation of clay suspensions, we demonstrate a hysteretic transition to oscillon-type states in a nongranular medium. When the symmetry of up-down reflection 1 time translation is lost, these states undergo a transition to propagating localized states previously seen...

A large part of the cytoplasm of the cells consists of components forming cytoskeleton. The constituents of the cytoskeleton in epithelial cells are actin-containing microfilaments, tubulin-containing microtubules and intermediate size filaments. The intermediate filaments are called as cytokeratins (CK). Thus, cytokeratins are a family of many different filamentforming proteins (polypeptides) ...

This paper reports on work in a neu branch of research in statistical methods: applications of interactive computer graphics. I describe several programs uritten for the Orion I workstation, an -experimental computer graphics system built at the Stanford Linear Accelerator Center in 1980-81. These programs demonstrate new methods for data analysis made possible by advances in microprocessor and...

The purpose of the study was to investigate the prevalence of β-haemolytic Aeromonas hydrophila strains in 83 samples from cooled horse mackerel, rainbow trout, Black sea roach, silver carp, vacuum-packed rainbow trout fillets and 20 samples frozen rainbow trout and to establish the minimum inhibitory concentrations (MIC) of several antimicrobial drugs against these strains. Forty-five Aeromona...

The aim of the present study was to characterize the action of the neurotransmitter, NO, on rat myenteric neurons. A NO donor such as GEA 3162 (10 moll) induced an increase in the intracellular Ca concentration as indicated by an increase in the fura-2 ratio in ganglia loaded with this Ca-sensitive fluorescent dye. The effect of GEA 3162 was strongly reduced in the absence of extracellular Ca s...
