The electrochemical properties of a pure liquid crystal are presented which lead to the conclusion that the nonreversible liquid crystal oxidation is the main cause of degradation in dc-driven devices. This phenomena is avoided by the use of electroactive dopants which fulfill the conditions established in Paper I. It…
In the tinplate food container it is to be desired that tin is the sacrificial member of the couple, conferring protection to the steel base while corroding at a slow rate itself. This is the case in many food products, including a large group of acid food products typified by the acid fruits. This is an important pac…
I n-situ x-ray data has been obtained on 99.99% pure cerium at 50 and 52 kbar with the use of a Bragg-Brentano parafocusing x-ray reflection technique under quasihydrostatic conditions, with a thermal cycling procedure. Our results, based upon 22 experimental diffraction lines, indicate that cerium metal exhibits a de…
Radiation degradation of cellulose fibers was investigated by gel permeation chromatography (GPC). Scoured cotton of Mexican variety (cellulose I), Polynosic rayon (cellulose II), and their microcrystalline celluloses obtained by hydrolysis of the original fibers were irradiated by Co-60 γ-rays under vacuum or humid c…
A number of hydrogel systems have demonstrated good tissue compatibility and low thrombogenicity in in vivo and in vitro tests ( 1 ). The poor mechanical properties of hydrogels have encouraged the development of techniques for reinforcing hydrogels to make them suitable for use in biomedical devices. By radiation gra…
A high-intensity ultrasonic apparatus was utilized to study the variation with strain amplitude ε of internal friction Q−1 and modulus defect ΔS/S in α-brass, as influenced by composition, grain size, and prestress. Q−1(ε) manifests three regions: I, where Q−1 is independent of ε; II, where Q−1 rises and then levels o…
Abstract Several formulations are available for the interpretation of reversed refraction profiles in terms of any number of plane dipping layers. Split-spread profiles can be interpreted using the same methods. This procedure requires that the intercept times at the origin from data in opposite directions be equal. I…
The antitumor effect of reserve polysaccharide, paramylon, from Euglena gracilis on the transplantable sarcoma-180 was examined in mice. This polysaccharide had an effect similar to that of lentinan. Paramylon, in a dose of 1 mug/g body weight, injected intraperitoneally 24 hr after tumor implantation had an inhibitor…

The report supplies the theoretical background and design techniques needed by an engineer who is designing electrical insulation for high-voltage high-power components, equipment, and systems on aircraft. A literature survey and abundant bibliography identify references that provide further data on the subjects of pa…
The crystal structure of Cs2HfCl6 was determined to be cubic, Fm3m, similar to K2PtCl6, with parameters: a0 = 10.42±0.01 Å, and u = 0.247±0.003. Powder diffraction data on which the determination was based are given.

The Tintinnida of the Woods Hole, Massachusetts region were identified during two consecutive summers; loricae of eleven species of the agglutinated variety were studied by scanning electron microscopy. There were distinct differences in the types of particles utilized. In some species, quartz was incorporated almost…
Abstract The kinetics of crystallization of alumina trihydroxide (hydrargillite) from caustic aluminate solutions of industrial composition (second stage BAYER process) were studied in a laboratory batch isothermal crystallizer. The yield and crystal size distribution of precipitate with time were obtained by varying…
Abstract Three soil profiles developed on a serpentinite body (La Rochel'Abeille, near Limoges) show three stages of weathering. All soils contain iron-rich smectites and secondary chlorites. The latter are very silica-rich, more so than 14 Å chlorites from crystalline rocks. In the (B) 1g horizon of the hydromorphic…
New intermetallic compounds of the ThCr 2 Si 2 -structure type have been prepared and their structures determined by single crystal data.
Fe2SiS4 and Fe2GeS4 have the olivine structure with space group Pnma. Cell dimensions are a= 12.407 (2), b=7.198(1), c= 5.812(1) /~ for Fe2SiS4 and a= 12.467(2), b=7.213(1), c= 5.902(1) /~ for Fe2GeS4. The crystal structures were refined by least squares to final values of R=0.052 and 0044 respectively for Fe2SiS4 and…

The simple method of solving the Green-Ampt one-dimensional infiltration equations developed from Darcy's law are proposed for practical applications. The explicit solution is an approximation obtained by employing a power series expansion of the logarithmic term. The maximum error resulting from applying this simple…
