The deformation of an ellipsoidal drop under viscous flow conditions
No full textA previously developed phenomenol. model for the deformation of a droplet immersed in a fluid subjected to a flow field (P. L. Maffettone, M. Minale; 1998) is tested to predict the drop transient behavior following the flow start-up and its relaxation upon cessation of flow. The model was then compared with expts. in which a shear device consisting of a parallel plate app. was used, and the fluids used were 2 immiscible polymers, polyisobutylene and polydimethylsiloxane. Comparison of theor. and exptl. data showed that both the start-up and the relaxation upon cessation fo flow is accurately predicted. The study is of interest with respect to blending and processing polymers

No full textSphinxolides A-D and the related macrolides reidispongiolides A and B were isolated from the sponges Neosiphonia
superstes and Reidispongia coerulea, resp. The macrolides were potent cytotoxins against several human carcinoma
cell lines. Neosiphonia superstes also contained two more unrelated but highly cytotoxic macrolides superstolides A and
B. A sponge of the genus Callipelta yielded the cytotoxic cyclopeptides callipeltins A-C which were found to protect cells
against infection by the human HIV virus
