The Modular High-Temperature Reactor
Nearly all problems encountered in large High-temperature reactor power plants with respect to design and safety are related to the mere physical size of a larger reactor core. Our analyses show that it is feasible to subdivide a larger reactor core into modular units, analogous to the common practice of using several…

Experimental Studies on Reflection Spectra in Monodomain Cholesteric Liquid Crystal Cells: Total Reflection, Subsidiary Oscillation and Its Beat or Swell Structure
Many optical properties are presented here in the reflection spectra for monodomain cholesterics of various cell thicknesses at various angles of incidence. It is reported for the first time that left-circularly polarized light incident on a left-handed helix gives rise to a beat structure in the subsidiary oscillatio…
On the Elastic Constants of a Nematic Liquid Crystal
Abstract Comparing an extended form of the Landau‐de Gennes model for the order parameter with the free elastic energy for the director field of a nematic liquid crystal the temperature dependence of the Frank elastic constants is found. The theoretical results are in agreement with both the recent measurements and wi…
Flexibility of collagen determined from dilute solution viscoelastic measurements
Abstract The frequency dependences of the storage and loss shear moduli, G ′ and G ″, of pronase‐treated collagen dissolved in acetate buffer at pH 4.0 were measured at 17.0°C by use of the Birnboim‐Schrag multiple lumped resonator apparatus. Some of the solutions contained 70% glycerol. The infinite‐dilution moduli w…

Temperature Dependence of the Static Relative Permittivity of Octylcyanobiphenyl (8CB)
Measurements of the relative static permittivity ε of octylcyanobiphenyl (8CB) in the smectic A, the nematic and the isotropic phases between 22°C and 140°C are reported. The resolution of the measurements was better than 0.01% and the temperature stability was better than 0.01 °C. Detailed measurements have been carr…

Determination of the anisotropic potential at the nematic liquid crystal-to-wall interface
The integrated birefringence of a surfactant (C16H33NH2)-aligned methoxybenzylidene butylaniline cell as a function of applied magnetic field (up to 100 kG) has been measured. The Oseen and Frank elastic continuum theory and a generalized torque balance equation at the interface have been utilized for the calculation…
Dielectric studies of water in epoxy resins
Abstract Dielectric measurements are reported on amine‐cured epoxy resin samples over a frequency range from 200 Hz to 200 kHz and a temperature range from −60°C to 70°C as a function of molecular weight of the diglycidyl ether and water content. The effects of change of the molecular weight of the diglycidyl ether on…
Fluid-absent metamorphism
Many interpretations of metamorphic parageneses tacitly assume that a free fluid phase was always present during metamorphic equilibration (fluid-present metamorphism), as opposed to the circumstance that, while volatile species are certainly released from minerals during metamorphism, these species may not saturate t…
An Introduction to the Burning Behaviour of Cellulosic Fibres
The actions of heat and flame on cellulosic fibres are compared with the physical and chemical behaviour of other fibres. The combustion mechanism is discussed in terms of concerted pyrolysis and oxidative stages, which can be represented as an energy feedback system. The action of different flame retardants are seen…
Pore Size Distribution in Porous Silicon Studied by Adsorption Isotherms
Porous silicon was obtained by anodic attack of single crystal silicon substrates in 25% hydrofluoric acid solutions. Specific surface area, total porous volume, and pore size distribution of porous silicon have been determined. The experimental technique used is based on the measurement of the volume of gas adsorbed…
Increased Thermal Stability of Collagen in the Presence of Sugars and Polyols1
The effects of sugars and polyols on the thermal denaturation temperature, Tm, of acid-soluble collagen from calf skin were studied at pH 4.0 under atmospheric pressure as well as high pressures up to 4,000 atm. Addition of these compounds invariably raised Tm with increases in their concentration over the whole range…
Analysis of anisotropic dielectric gratings
A method for analyzing slanted anisotropic gratings is presented. The propagation of electromagnetic waves in the periodic anisotropic media is described by coupled-wave equations in a unified matrix form expressing the coupling of the space harmonics in the grating region. The solution of the equations is reduced to…
Long-range surface-plasmon modes in silver and aluminum films
We report the first observation to our knowledge of a sharp minimum in the attenuated total reflectivity of a thin metal film between index-matching layers. The resonance is due to the excitation of the long-range surface-plasmon mode on both sides of the thin metal films, as originally discussed by Sarid [Phys. Rev.…
Computer simulation of the dynamics of hydrated protein crystals and its comparison with x-ray data.

The obtained structure, atom positional fluctuations, and structure factors are compared with x-ray valu…
Revised Phase Diagram of the System ZrO 2 ‐CeO 2 Below 1400°C
The phase diagram of the system ZrO 2 ‐CeO 2 was rein‐vestigated using hydrothermal techniques. Cubic, tetragonal, and monoclinic solid solutions are present in this system. The tetragonal solid solution decomposes to monoclinic and cubic solid solutions by a eutectoid reaction at 1050°50°C. The solubility limits of t…
