Leukotriene C4 induces vasogenic cerebral edema in rats
(Elsevier, 1984-06)
Leukotriene C4 (LTC4) is reported to neither contract nor relax isolated human cerebra artdial strips (1), but in skin LTC4 will increase vascular permeability in post capillary venules, increase blood flow (2) and elicit ...
Effect of fiber inclination on crack bridging stress in brittle fiber reinforced brittle matrix composites
(Elsevier, 1992-08)
behavior of brittle matrix composites is strongly affected by the bridging of cracks by fibers. In random fiber composites, fibers can lie at an angle to the crack plane. Under such conditions, the bridging stress for a ...
Texture Development, Microstructure Evolution, and Crystallization of Chemically Derived PZT Thin Films
(American Ceramics SocietyBlackwell Publishing Ltd, 1998-01)
The annealing and thermal analysis of poly(butylene terephthalate)
(John Wiley & Sons, Inc., 1994-04-15)
When poly(butylene terephthalate) (PBT) is annealed, a second endotherm is often displayed in a subsequent scanning thermal analysis at a temperature below that of the original endotherm, and this new endotherm appears to ...
Small angle X-ray scattering from coal-derived liquids
(Elsevier, 1982-05)
Small angle X-ray scattering measurements were used to determine the size and shape of asphaltene and preasphaltene micelles in solution. The fraction of the coal-derived liquids forming micelles in solution was as high ...
Interaction of linear manno-oligosaccharides with three mannose-specific bulb lectins. Comparison with mannose/glucose-binding lectins
(Elsevier, 1992-05-22)
Three new mannose-binding lectins, isolated from daffodil (NPA), amaryllis (HHA), and snowdrop (GNA) bulbs, are capable of precipitating with a linear mannopentaose (Man[alpha]1-3Man[alpha]1-3Man[alpha]1-3Man[alpha]1-2Man). ...
Effect of AlN and Al2O3 additions on the phase relationships and morphology of SiC Part I Compositions and properties
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-11)
X-ray diffraction was utilized to follow the transformation from β-SiC (3C) to the various α-SiC polytypes in the presence of AlN and Al 2 O 3 additives after hot pressing from 1700 to 2100°C. The 2H- and 6H-polytypes of ...
Extensional flow behavior of polymer solutions and particle suspensions in a spinning motion
(Elsevier, 1974-06-17)
Mechanical spinning of fluid filaments was used to generate an extensional flow, in which rheological measurements were obtained for a Newtonian fluid, two aqueous polymer solutions, and two fluid suspensions of rod-shaped ...
