Opephora parva, O. pacifica and O. perminuta are commonly reported from brackish and marine sediments worldwide, but their true identity is unclear. Therefore, isotype material of these three taxa was examined using light microscopy. In addition, several populations from different localities in Europe, Africa, South A…
An Oligocene through early Miocene diatom zonation is proposed for the North Pacific based on the stratigraphic documentation and illustration of diatom taxa from Hole 884B on the eastern flank of Detroit Seamount in the northwest Pacific. The Hole 884B section is unique in the North Pacific because it contains a near…
Controlled amounts of GaP and P were added to a Si0.8Ge0.2 matrix by a powder-metallurgical technique in order to evaluate the optimum composition for thermoelectric applications. Bulk determination of the gallium and phosphorus content in fully dense, hot pressed compacts was performed by inductively coupled plasma a…
Complex hydrodynamics near the moving contact line control spreading of a fluid across a solid surface. In the confined region near the contact line, velocity gradients in the fluid are large and viscous forces control the shape of the fluid/fluid interface. The present model for liquid spreading describes the viscous…
The solubility of paracetamol was determined as a function of temperature in mixtures of wide polarity range (ethyl acetate:ethanol and ethanol:water) to compare the solvation effects of amphiprotic and amphiprotic-aprotic solvent systems. The mole fraction solubility of the drug showed solubility maxima at δ1 = 14·53…
A divalent metal ion-stimulated protein-serine/threonine phosphatase, PP1-arch, was purified approximately 1,000-fold from the extreme acidothermophilic archaeon Sulfolobus solfataricus (ATCC 35091). Purified preparations contained 40 to 70% of total protein as PP1-arch, as determined by assay-ing sodium dodecyl sulfa…

The objective of the work reported here was to characterize the tarnish products formed on copper during the early stages of exposure to moist air with trace levels of pollutant gas, in particular, sulfur dioxide and sulfur dioxide/nitrogen dioxide. A mixed‐flowing‐gas chamber was used to control part per billion (ppb…
Chain molecules formed from m tangent hard-sphere segments are of particular interest in studies of liquid crystalline phases because they represent one of the simplest models which can account for molecular flexibility. In this paper we obtain analytical expressions for the excluded volume for a pair of linear homonu…

The damage produced by displacement cascades in the h.c.p. metal α-titanium at 100K has been investigated by molecular dynamics using a many-body interatomic potential. This has been the first simulation of cascades in the h.c.p. structure. 32 cascades ranging in energy from 0.3 to 5 keV were generated in order to stu…
Combined high-resolution neutron and x-ray diffraction experiments have been performed on several differently prepared single crystals of ${\mathrm{SrTiO}}_{3}$ in order to investigate the two length scales present near the cubic-to-tetragonal phase transition occurring at ${\mathit{T}}_{\mathit{c}}$\ensuremath{\sim}1…
Reasonable assumptions about the statistical properties of errors in an atomic model lead to the probability distributions for the values of structure-factor phases. These distributions contain some generally unknown parameters reflecting how large the model errors are. These parameters must be determined properly to…
The peculiar polar properties of ${\mathrm{KTa}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Nb}}_{\mathit{x}}$${\mathrm{O}}_{3}$ (KTN) are determined by the presence of electric dipoles associated with randomly distributed Nb off-center ions. Because the latter also possess an elastic quadrupole, they should permi…
Abstract The application of phenol-formaldehyde resins as crosslinking agents is increasing in importance due to the good high temperature properties of the corresponding vulcanizate and the use in thermoplastic vulcanizates. With respect to the chemistry of phenol-formaldehyde cure (reaction mechanism and structure o…
An InP epitaxial layer with a dislocation-free area was obtained for the first time on (001) Si substrate by using the epitaxial lateral overgrowth (ELO) technique. Most etch pits appeared in the region over the seed area on the ELO stripe. This indicates that the SiO 2 film between the lateral overgrowth layer and th…
It has long been recognized that Ni-Ti shape memory alloys (SMAs) behave pseudo-elastically above the austenite finish temperature (Af) with a nearly perfectly plastic character during the initial cycles of transformation. Under conditions of cyclic loading with a maximum strain ∈ max , the critical stress to initiate…
Epitaxial thin films of BaTiO3 have been prepared using radio-frequency magnetron sputter deposition on MgO(100) substrates. Various x-ray-diffraction techniques were employed to characterize the crystal structure of the films. The films were fully tetragonal and consisted of c domains. Their tetragonality has been sh…
