A series of experiments was conducted to study in vitro and in vivo metal ion release and the urine excretion of metal ions. Metal salts were injected and urine analyzed. Anodic potentials were applied to stainless steel and cobalt-chromium-molybdenum (CCM) specimens to cause an acceleration of corrosion rates. Corros…
Using real-space renormalization-group techniques, an exact decimation transformation has been derived for the parameters characterizing the phonon or tight-binding properties of a one-dimensional quasicrystal, the Fibonacci chain, for the discrete rescaling factor \ensuremath{\tau} (the golden mean). A Green's functi…
Rotational viscosity and spontaneous polarization are the most important properties of a ferroelectric liquid crystal with regard to its switching time in surface stabilized or a.c. field stabilized displays. Whereas there is an abundant literature about spontaneous polarization, only a few attempts have been made to…
Excellent bistability was demonstrated in a ferroelectric liquid crystal electrooptic device prepared using polyimide Langmuir-Blodgett films for the orientation of the liquid crystals without performing rubbing.
Abstract The crosslinking of LDPE resulting from reaction with dicumyl peroxide at 180°C is increased in the presence of maleic anhydride (MAH). The presence of electron‐donating nitrogen‐containing compounds (amides, lactams, disubstituted aromatic amines, and amine oxides), phosphorous‐containing compounds (phosphit…
Rat intestinal fatty acid-binding protein (I-FABP) is an abundant cytoplasmic protein which is synthesized in the small intestinal lining cell where it is thought to participate in the absorption and intracellular metabolism of fatty acids. Each mole of this 132-residue polypeptide binds 1 mol of long chain fatty acid…
Various superconducting glass ceramics based on the Bi-Ca-Sr-Cu-O system with T c (onset)=80∼95 K and T c (zero)=63∼78 K were prepared by a melt-quenching method. The melt-quenched samples of Bi 1.5 CaSrCu 2 O x and Bi 1.5 Ca 1.5 SrCu 2 O x were found to be a glass with a glass transition of about 425°C; these samples…
Abstract A pair of aliphatic amines were synthesized in order to study the effect steric hindrance has on the physical properties of an amine‐cured epoxy resin. The hindered amine (TMSiDA) has NH 2 groups that are obstructed by the presence of adjacent methyl groups while the unhindered amine (SiDA) does not contain a…
The dispersive and polar surface‐energy components, as well as the total surface energy, of tin oxide coatings on soda–lime–silica glass were determined by the Owens–Wendt method. The total surface energy of tin oxide is greater than soda–lime–silica glass and, more importantly, exhibits significantly more‐dispersive…

DSC measurements of four kinds of acrylic fibers (Dralon X-100, Dunova, Acryl, and Aqualon) were made after equilibration with various amounts of water. The DSC curves in heating from -80° to 20°C were analyzed to obtain information on the state of water in these fibers. The results show that in a water-saturated stat…
The effects of various testing parameters on the accelerated life test results of 15 kV underground residential distribution cables prepared from thermoplastic and crosslinked polyethylene insulation are considered. Testing parameters included dry versus water in the strand, voltage stresses 4X(34.6 kV) and 3X(26.0 kV…

Oriented lamellar eutectic composites of NiO and ZrO 2 (CaO) platelets were reduced in CO 2 /CO gaseous atmospheres to form metallic Ni between the zirconia plates. The relatively rapid longitudinal reduction of NiO is described by a local cell electrochemical model whereby oxide ions are conducted from the Ni/NiO int…
Properties of the \ensuremath{\alpha} and \ensuremath{\beta} phases of solid ${\mathrm{O}}_{2}$ are calculated with a deformable-cell Monte Carlo method and the character of the associated phase transition is delineated. We find that the monoclinic \ensuremath{\alpha} phase is stable at temperatures T\ensuremath{\less…
Abstract Synthetic Eu-anorthite of the alkali feldspar structure type has been refined to R w = 4.7% using 3-D counter diffractometer data and full-matrix least-squares methods. The chemical composition of the feldspar is Eu 0.92 Al 1.76 Si 2.24 O 8 , based on both occupancy refinement of the Eu atom site and estimati…
The photoluminescence characteristics of undoped and TbCl3-doped zinc oxide films deposited by the spray pyrolysis technique are reported. Undoped films present the characteristic blue-green emission peak at ∼508 nm observed in single-crystal and powder ZnO. The TbCl3-doped films present a luminescence peak at ∼540 nm…
