Darlingtonia californica is a carnivorous plant with a patchy distribution in coastal Oregon and northern California, USA. A number of arthropod species inhabit and exploit its fluid-filled pitchers; among these is a hististomatid mite, Sarraceniopus darlingtonia, an obligate inhabitant that feeds on the rich microbial growth associated with decomposing arthropods captured by the pitcher. Males...

Introduction DEGENERATING axons of cephalopod material can be stained with a Cajal method (Sereni and Young, 1932). Whilst this has proved extremely valuable for demonstrating principal fibre connexions, it becomes more difficult to interpret the results when identifying degenerating fibres which are diffusely distributed within neuropil, or in tracts composed mainly of normal fibres. This is l...

The action of peritoneal exudate cells (PEC) from normal and vaccinia virus infected mice on infectious vaccinia virus particles was investigated in vitra. PEC from immune mice showed a significantly higher infectivity titre reduction (virus clearance, VC) than normal cells. This effect could be clearly attributed to the macrophage. Vaccinia virus multiplied in PEC from normal animals while the...

The long term goal is to develop a robust ocean prediction system for the North East US coast that efficiently exploits all the available observational platforms combined with the Regional Modeling System (ROMS). The system is now operating in real-time and forecasts of the state of the ocean six days in the future are posted daily at www.myroms.org/espresso. The project summarized here support...

This is a rare syndrome, characterised by an acute, life-threatening, non-inflammatory encephalopathy and fatty degeneration of the liver with minimal or no clinical signs of liver involvement. In classic Reye's syndrome, there is a severe but self-limiting disturbance of mitochondrial structure and associated enzymatic disturbances usually lasting about six days. This is accompanied by an inte...

A prototype system for the fine-grained filtering of news items has been developed and a pilot test has been conducted. The system is based on an adaptive user model that integrates stereotypes and artificial neural networks. The stereotypes are based on newspaper sections and sub-sections, along with editor specified and user specified keywords. Eight subjects trained the system over six days ...
