In this article we generalize the notion of complete parts, by introducing a weaker condition in definition. Using this generalization we define and analyse a new class of semihypergroups, which are called weak complete semihypergroups. Complete parts were introduced about 40 years ago by M. Koskas and they represent a basic notion of hyperstucture theory, utilized in constructing an important ...

—The large plagioptychid rudist bivalve Mitrocaprina tschoppi (Palmer) is recorded from the Guinea Corn Formation (Late Maastrichtian) of central Jamaica. This is the first record of this species outside of Cuba. M. tschoppi occurs in rhythm D6 of the Guinea Corn Formation, Macgillavryia Bed 1, together with a rudist assemblage including Praebarrettia sparcilirata (Whitfield), Macgillavryia nic...

Giant lipomas, although rare, represent a real diagnostic and therapeutic challenge. We report an unusual giant lipoma of the thigh extending into two thigh canals and it's diagnostic and therapeutic processes.

This study used a mechanical test to evaluate the flexibility of instruments from the K3 (conicity 0.04) and the ProTaper Universal systems when they were new and after 5 uses in simulated canals. Five sets of instruments of each system were tested: K3 (15, 20, 25, 30, 35, 40 and 45) and ProTaper Universal (S1, S2, F1, F2, F3, F4 and F5). Each set of instruments was used to prepare a simulated ...

The cytoskeleton regulator UNC-53/NAV2 is required for both the anterior and posterior outgrowth of several neurons as well as that of the excretory cell while the kinesin-like motor VAB-8 is essential for most posteriorly directed migrations in Caenorhabditis elegans. Null mutations in either unc-53 or vab-8 result in reduced posterior excretory canal outgrowth, while double null mutants displ...

http://www.aic.gov.au Adam Graycar Director In 2000, 139,000 motor vehicles were stolen in Australia. About 80 per cent of these were recovered soon after the theft. It is estimated that about threequarters of motor vehicle thefts are opportunistic, stolen for joy-riding or transport, and one-quarter are stolen for profit. Many that are stolen for profit end up as spare parts. Very little is kn...

We present a variational approach to the problem of registering planar shapes despite missing parts. Registration is achieved through the evolution of a partial differential equation that simultaneously estimates the shape of the missing region, the underlying “complete shape” and the collection of group elements (Euclidean or affine) corresponding to the registration. Our technique applies bot...

Parts manufactured to tolerances have shape variations. Most work in robotic manipulation assumes that part shape does not vary. Orienting devices such as bowl feeders frequently fail due to variations in part shape. In this paper we develop techniques to orient parts with shape uncertainty. We present a shape uncertainty model and describe the nondeterminism in parts orienting that arises from...

Could a human being survive the complete death of his brain? I will argue that the answer is no. No human organism can survive the loss of its irreplaceable parts. Hence, when an irreplaceable part is gone, whatever remains is not numerically identical with the organism that existed previously. If you were the original organism, then you do not survive as the residuum. In this paper I give an e...
