This paper addresses overload characteristics of thermoset dielectric power cable systems. Present industry specificationsl, 2 recommend a maximum emergency conductor temperature of 130°C. The suitability of this temperature and the time it is to be maintained has been questioned. The present work indicates that cross…
Abstract In this study, natural, delaminated and silane‐treated micas were screened to give fractions passing 60 to 325 screen mesh sizes. The micas were used as fillers (to 80 wt. percent) in plasticized PVC compounds, their dispersion behavior and their effects on mechanical properties of compounds being noted, and…
Abstract Polymers with conductivities from 8.6 × 10 0 to 7.3 × 10 −6 (ω cm) −1 at 2–12 kbar were prepared by zinc‐chloride‐catalyzed condensation of polycyclic aromatic hydrocarbons, heterocycles, and quinones with pyromellitic dianhydride, tetrabromophthalic anhydride, and tetrachlorophthalic anhydride at 450°C. Thes…
The piezoelectric resonance method was adopted in order to measure piezoelectric and elastic constants of polyvinylidene fluoride films over the temperature range from −40 to 60 °C and at pressure up to 3 kbar. We have shown that the glass transition temperature increases with pressure, dTg/dP being approximately equa…
Atom Probe Field-Ion Microscopy and Transmission Electron Microscopy have been used to characterize the microstructure and to determine the changes that occur during long-term low-temperature aging of primary coolant pipes used in pressurized water nuclear reactors. The cast CF 8 type stainless steel forms a mixture o…

A family of variable-index spherically symmetric lenses is presented that provide the light focusing at two (or three) points, subject to an appropriate division of the aperture.
A procedure which permits the evaluation of the stress-strain field in an elastomeric seal is presented. Such a procedure is based upon a mechanical modeling of the elastomer and on the employ of finite elements which can cope with high strains. Finally, the above-mentioned procedure is checked against experimental re…

The solubility of 17 beta-oestradiol (E2) in aqueous solutions of polyethylene glycol (PEG) 400 has been measured at 35 degrees C. Up to 80% w/w PEG the solubility data conform to a log linear equation ln S = ln Sw + f sigma where S is the E2 concentration in the water/cosolvent mixture, Sw is E2 solubility in water,…
Measurements of Mössbauer absorption spectra of 57 Fe : La 2 Ni O 4 at 297, 77, and 4.2 K provide evidence, at the lowest temperatures, of magnetic order in a sample containing 57 Fe 3 + -ion impurities and some La 2 + n Ni 1 + n O 4 + 3 n intergrowth.

The bremsstrahlung cross section has been studied by measuring the activity induced in $^{63}\mathrm{Cu}$ by electrodisintegration and when thin radiators of Cu, Mo, Ta, and Th were placed in the electron beam just ahead of the target. The electron energies were varied from 13.5 to 60 MeV for the electrodisintegration…
Natural and synthetic fibres and fabrics have been modified in cold plasma conditions in order to impart new qualities to support materials. Both static and dynamic installations designed to this aim are presented. Improved hydrophilicity, dyeability and flamme retardancy properties were achieved by grafting with eith…
Abstract The anodic oxidation of NH 2 OH on Pt in neutral and acid solutions was studied using CV, RRDE and Mass Spectroscopic Cyclic Voltammetry. Thus, the i /ϕ‐curves obtained could be correlated to the rates of formation of the gaseous products N 2 , N 2 O t NO and NO 2 . Three anodic waves were distinguished, each…
ABSTRACT The initial epivalve of Rhoicosphenia curvata (Kütz.) Grun. differs from vegetative valves in having a strongly arched section, a wide hyaline marginal strip, no pseudosepta, an unthickened margin, and a terminal raphe fissure at the head pole. The initial epivalve is of the D type, with short raphe fissures.…
