Similarities in the fracture surface features of borosilicate and polymer glasses
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-10)
Considerable similarity exists between the features on the fracture surfaces of a borosilicate glass and those on the fracture surfaces of polymer thermoset glasses like epoxies and vinyl esters. These features include the ...
Effect of gravity on Brownian flocculation
(Elsevier, 1984-09)
In previous analyses of simultaneous Brownian and gravity-induced flocculation, it has been assumed that each mechanism contributes independently to the total flocculation rate. In this paper the rigorous problem of coupled ...
Stereochemistry in the cyclization of -azidophenylalkenes to indoles
(Elsevier, 1983)
- and --azidostilbene, -azido-[beta]-methylstilbene, and ()--azido[beta]-deuteriostyrene give indoles on thermolysis by a mechanism involving attack by a nitrene directly on the [beta] carbon atom, and not by insertion.
Transition dipole interaction in polypeptides: Ab initio calculation of transition dipole parameters
(Elsevier, 1984-06-15)
Ab initio calculations of dipole moment derivatives of a model system of N-methylacetamide hydrogen-bonded to two formamide molecules give values for amide I and amide II transition dipole moments consistent with those ...
A petrographic thin sectioning technique for evaluating composite materials
(Kluwer Academic Publishers; Chapman and Hall Ltd. ; Springer Science+Business Media, 1989-08)
Human neutrophils permeabilized with digitonin respond with lysosomal enzyme release when exposed to micromolar levels of free calcium
(Elsevier, 1986-04-08)
We have recently reported that human neutrophils can be permeabilized with the cholesterol complexing agent saponin and that these cells can be induced to secrete the granule enzyme lysozyme in response to micromolar levels ...
Texture Development in YBa 2 Cu 3 O x by Hot Extrusion and Hot-Pressing
(Blackwell Publishing Ltd, 1987-12)
A Monte Carlo-finite element model for strain energy controlled microstructural evolution: "rafting" in superalloys
(Elsevier, 1989-02)
A specialized microstructural model, MCFET, has been developed which simulates microstructural evolution in materials in which strain energy plays an important role in determining morphology. The elastic contribution to ...
Mixed-crystal infrared study of chain mobility in untreated and nitric-acid-treated polyethylene single crystals
(John Wiley & Sons, Inc., 1983-11)
No Abstract.
Binding of Griffonia simplicifolia I lectin to rat pulmonary alveolar macrophages and its use in purifying type II alveolar epithelial cells
(Elsevier, 1986-01-23)
We report that the isolectin Griffonia simplicifolia I-B4 isolated from G. simplicifolia seeds binds to rat alveolar macrophages present in frozen sections of lung tissue or bronchoalveolar lavage fluid. G. simplicifolia ...
