Recently we purified and cloned the mitogen/oncogene-activated Mr 70,000 (70K) S6 kinase from the livers of rats treated with cycloheximide (Kozma, S. C., Lane, H. A., Ferrari, S., Luther, H., Siegmann, M., and Thomas, G. (1989) EMBO J. 8, 4125-4132; Kozma, S. C., Ferrari, S., Bassand, P., Siegmann, M., Totty, N., and…
A practical method is presented for computing high-frequency ferrite core losses in the magnetic component for arbitrary voltage waveforms. The model presented requires only a few material parameters as input. To calculate ferrite hysteresis losses, a model based on empirical rules is employed. For high-frequency eddy…

Potential‐pH equilibria and potentiodynamic polarization studies were used to confirm that formation of complexes in and solutions produces a range of potentials at which anodic dissolution of copper occurs without formation of oxide. The interaction of benzotriazole (1 g/l) with oxide‐free copper surfaces in the chlo…

New results are presented in the area of hysteretic modeling and experimental characterization of shape memory alloys (SMAs). A stress‐induced micromechanical phase transition occurs in SMAs that causes inelastic deformation and gives rise to a large energy‐absorbing capacity. Because it is possible to achieve large h…
Protein adsorption from human plasma was investigated on phospholipid polymers, poly (2-methacryloyloxyethyl phosphorylcholine (MPC)-co-n-butyl methacrylate (BMA) or glass by radioimmunoassay and immunogold labeling techniques. In the present studies the focus was to determine the composition and distribution of prote…
The complex permeability ( mu /sub r/) and permittivity ( epsilon /sub r/) spectra at X-band frequencies and their relationship with microwave absorbing properties are investigated in ferrite-rubber composite material. Multifrequency measurements of mu /sub r/ and epsilon /sub r/ are made by the reflection/transmissio…
The neutralization of highly charged ions during interaction with metallic surfaces is accompanied by the ejection of a large number of secondary electrons. Recent experiments demonstrate two main contributions to this electron ejection process: one from the region below the surface and the second from the above-surfa…
The specification of a new standard Crystallographic Information File (CIF) is described. Its development is based on the Self-Defining Text Archive and Retrieval (STAR) procedure [Hall (1991). J. Chem. Inf. Comput. Sci. 31, 326-333]. The CIF is a general, flexible and easily extensible free-format archive file; it is…
Abstract We have recently reported on the consecutive physisorption of anionic and cationic bipolar amphiphiles onto charged surfaces, adsorbed out of aqueous solutions [1]. Here, we extend our previous concept to multipolar compounds such as polyelectrolytes. In contrast to the bipolar amphiphile system, it is not ne…
A theory is presented to predict the pullout work and ultimate tensile strength of ceramic‐matrix composite (CMC) materials tested under uniaxial tension as functions of the underlying material properties. By assuming that the fibers fracture independently and that global load redistribution occurs upon fiber fracture…
Erbium-doped yttria-stabilized zirconia (YSZ) single crystals of 84ZrO 2 /16YO 1.5 composition have been studied by electron paramagnetic resonance (EPR), optical absorption and photoemission techniques at temperatures between 10 and 680 K. At 10 K the Stark-structure of the 4 I 15/2 and 4 S 3/2 multiplets has been re…
A Mach–Zehnder interferometer with a pulsed dye-laser light source is used to observe the collapse of laser-produced cavitation bubbles in water near a rigid transparent polymeric boundary. Vapor bubbles with a maximum radius of about a millimeter are formed using a Q-switched Nd:YAG laser operating at 1.06 μm with a…
Third-harmonic generation measurements have been made for the first time on oriented films of halogen-bridged mixed-valence platinum complexes for the pump wavelength region from 0.6 to 1.0 μm. The ‖χ(3)(−3ω;ω,ω,ω)‖ spectra obtained by the Maker’s fringe method show a distinct peak at about 1.8 eV with the peak value…
We have studied the chemical vapor deposition of copper from 1,5-cyclooctadiene Cu(I) hexafluoroacetylacetonate, a moderately volatile yellow cystalline solid. It yields pure copper by pyrolytic decomposition at 150–250 °C, produces copper films with near bulk resistivity, and has the advantage of being air stable at…
Depositing alkali metal into a molecular oxygen layer dispersed on a Kr film produces alkali-metal superoxides containing the ${\mathrm{O}}_{2}^{\mathrm{\ensuremath{-}}}$ species for photoemission and near-edge study. The O K-edge spectrum of ${\mathrm{LiO}}_{2}$, ${\mathrm{KO}}_{2}$, and ${\mathrm{CsO}}_{2}$ is in go…
Direct evidence for the creation of oxygen-vacancy, oxygen-interstitial pairs in ${\mathrm{SiO}}_{2}$ glasses by an excitonic mechanism is developed from an electron-spin-resonance study of high-purity fused silicas exposed to highly focused 6.4-eV excimer laser light.
A relation for the temperature evolution of multicomponent porous ices is derived from the energy equation of multicomponent systems. It is demonstrated that the predominant energy transfer mechanisms can be incorporated into an effective thermal conductivity (λ e ƒƒ ), which is strongly temperature dependent, and tha…
