Unusual Type

Miller's technique was applied to isolated nuclei of rat liver. Both the usual nucleolar and non-nucleolar transcription complexes were visualized. In addition, an unusual type of putative non-ribosomal transcription unit was revealed. It was charcaterized by a high density of the lateral ribonucleoprotein (RNP) fibrils. Although these particular units exhibited a regular increase of fibril lengths, the length of the transcript-covered deoxyribonucleoprotein (DNP) fibres and the morphological aspect of the RNP fibrils distinguished them from the nucleolar ‘Christmas-tree’-like figures. The linear and granular configuration of the transcripts and the absence of terminal knobs made them similar to non-nucleolar nascent RNP fibrils.

Water Simulation

This paper presents an investigation of the still water sink trajectories of an accidentally dropped Christmas Tree (XT). A 3D coupled nonlinear dynamics/hydrodynamics model of the XT is constructed and simulations executed from surface to seabed. XT initial water entry orientations are randomly varied in a Monte-Carlo simulation to predict the seabed impact zone. Still water simulation results are compared to simplified cone-angle type method predictions. The effect of XT flat panels on excursion mitigation is investigated. Finally, the influence of non-uniform current effects is studied.
