Tapered pole

Other characters that generally corroborate the Urediniomycetes are the 5S rRNA secondary structure of type A [236], plate-like spindle pole bodies, the cell wall monosaccharide pattern (table 1) and simple septa tapering towards the pore or poreless septa [22, 217, 234, 335, 336, 340, 343-348]. The members of this class are predominantly dimorphic except the Uredinales...

A dorsal and a ventral leaf usually are distinguished in the PO in the cat the ventral leaf is continuous with the medial pole of the dorsal accessory olive. In other mammals the DAO is continuous with the dorsal leaf and the ventral leaf ends as the DMCC in macaque monkeys and at the DM in rats. The ventral leaf of the PO caudally tapers into the ventrolateral outgrowth (VLO) that continues as the dorsal cap (DC) of Kooy (1917), located dorsal to the group beta. 

A EXPERIMENTAL FIGURE 20-35 Cytosolic dynein participates in the formation and stabilization of mitotic spindle poles. In vitro reconstituted spindles were stained with fluorescently-labeled polyclonal antibodies to tubulin (green) and dynein (red) and examined with a fluorescence microsope. In the control spindle left), cytosolic dynein is present at each tapered end, as well as at the equator. Addition of a dynein monoclonal antibody after the formation of the spindle right) disrupts dynein localization and causes the poles to splay. [From R. Fleald et at, 1997, J.

To produce a curved tapered pipe, a flexible mold is used. This is bent to the required shape once the preform has been placed in position. It is also claimed that base plates can be simultaneously molded on by this method. These base plates are first preformed and then inserted into the mold where they become firmly bonded into the pole. Typical applications include poles for street lighting, flag poles and aerials.
