The fracture characteristics of an Al 2 O 3 /Al composite are examined. Measurements of resistance curves and work of rupture are compared with predictions of a micromechanical model, incorporating the effects of crack bridging by the Al reinforcements. The bridging traction law is assumed to follow linear softening b…
The nonlinear optical properties of organo‐mineral salts based on 2‐amino‐5‐nitropyridine (2A5NP) and tartrate anions are presented. The mineral anion provides improved structural cohesion compared to van der Waals or hydrogen‐bonded organic molecular crystals while the organic species is responsible for the nonlinear…
The dynamics of a two-dimensional shell model with a double-well potential in the core-shell interaction is simulated by means of molecular-dynamics techniques. Snapshots of the lattice displacement pattern reveal the presence of precursor regions in the high-temperature phase, while in the low-temperature phase the d…

OBJECTIVE: Perflubron emulsion is a bromine-based particulate contrast agent that is taken up selectively by the liver and spleen after IV injection. It does not leave the vascular space and also persists in the blood for a longer period than iodinated contrast agents do. We performed a preliminary study to determine…
A small-angle cleavage technique has been developed that produces superior transmission electron microscope (TEM) samples of semiconductors and related materials. The technique involves back-thinning the sample to approximately 100 microns, then scribing a groove on this back face at a specified small angle to a stand…
A quantitative investigation on the effects of plasma proteins and platelets on the adhesion of Staphylococcus epidermidis RP62A to a hydrophobic biomedical polymer (National Heart, Lung, and Blood Institute reference polyethylene) was carried out under well-defined shear conditions approximating human blood circulati…
The mechanism of red-pumped frequency-upconversion fluorescence observed in the uv and blue ranges of frequencies for a ${\mathrm{Tm}}^{3+}$-doped fluoroaluminate glass was investigated by single-wavelength pumping of a tunable 4-(dicyanomethylene)-2-methyl-6-(p-dimethyl-amino-styryl)-4H-pyran dye laser. It was found…
The binary collision code MARLOWE is used to study cascade sizes, defect densities and subcascade configurations in f.c.c., b.c.c. and h.c.p. metals as a function of recoil energy up to 1 MeV. The threshold energies for the formation of subcascades are determined using a definition based on the defect configuration af…

Single crystals of Cs3Yb2Br9 were grown using the Bridgman technique. Well-resolved absorption, luminescence, excitation, and Raman measurements down to 5 K are reported and analyzed. The crystal-field splitting of Yb3+ in Cs3Yb2Br9 was determined and can be rationalized in terms of a trigonally distorted YbBr63− octa…
Abstract This review describes the chemistry of cyclophosphazene and polyphosphazene ligand systems and their transition and organometallic complexes. The structures of the ligands and the complexes are discussed.
Abstract Reinterpretation of published data for shale cuttings from the Gulf of Mexico sedimentary basin identifies three reaction zones for illite formation with increasing depth for well CWRU6. In a shallow zone (1.85 to 3 km), non-expanding illite-like layers formed primarily by the coalescence of smectite 2:1 laye…
Coexpression of the yeast N-myristyltransferase with the murine catalytic subunit of cAMP-dependent protein kinase in prokaryotic cells results in the N-myristylation of the recombinant catalytic subunit. The acylated recombinant catalytic subunit was purified following in vitro holoenzyme formation with a mutant form…

The hydrodynamic stability of steady axisymmetric thermocapillary flow in a cylindrical liquid bridge is investigated by linear stability theory. The basic state and the three-dimensional disturbance equations are solved by various spectral methods for aspect ratios close to unity. The critical modes have azimuthal wa…
