The authors calculated values for the ratios of the double-electron to main-line strengths with their corresponding excitation energies for the ${\mathit{LN}}_{4,5}$ edges of elements found in the sixth row of the Periodic Table. In addition, the approximate analytical forms for the relative intensities in terms of mo…
Abstract The <2 µm fraction from the eluvial horizon of a humus-iron podzol is composed predominantly of a dioctahedral mineral with a basal spacing of 14.7 Å which contracts to 13.7 Å on solvation with glycol, and to 11.4 Å on heating to 300°C. The interlayer region is partially filled with an amorphous organo-Fe-…

The eex gene(s) of pKM101, which mediates that plasmid's entry exclusion phenotype, is located within a cluster of tra genes that are thought to encode a mating bridge. We have determined the DNA sequence of the region containing eex, including the points of insertion of two flanking tra::Tn5 insertions. Sequence anal…
A theory of ionic transport in polymer electrolytes is presented based on ionic environments reorganizing randomly into one another. This differs from previous work by allowing for Langevin like motion rather than instantaneous hops, by including possible carrier motion attached to moving segments, and by providing fo…
It is noted that when details are correctly designed and specifications are properly prepared and complied with, the repair process will possess properties that will be serviceable and durable. The paper delineates some of the major issues to consider in achieving long-lasting concrete repairs. Comments are made on th…
A vibrational technique for the measurement of stress in films has been developed, based on the theory of membranes. Specimens for vibrational analysis are prepared by removing a circular or square piece of the substrate. It is shown that the error introduced due to substrate removal is negligible except for thin meta…
Polyoxometalates are soluble mineral compounds formed principally of oxide anions and early transition metal cations. The polyoxometalates K12H2[P2W12O48].24H2O (JM 1591), K10[P2W18Zn4(H2O)2O68].20H2O (JM 1596), and [(CH3)3NH]8[Si2W18Nb6O77] (JM 2820) demonstrate potent antiviral activity against human immunodeficienc…

Some aspects of physico-chemical behaviour of thermotropic liquid-crystalline (LC) polymers with mesogenic side groups (comb-shaped polymers) are considered in connection with the peculiarities of their molecular structure. The relationship between molecular parameters, such as molecular weight and molecular weight di…

A galvanic series was developed for a variety of thin‐film metallizations and barrier layers deposited on oxidized Si substrates. The series was determined by listing the stable open‐circuit potentials of thin‐film metallizations, barrier layers, and metal/barrier‐layer couples that were evaluated using a 2000 ppm ele…

Abstract Parkinsonite, ideally (Pb,Mo,□) 8 O 8 Cl 2 , is a new mineral from the Merehead Quarry, Cranmore, Somerset, England. It occurs as compact clusters or patches of red to purplish red bladed crystals, which have an adamantine lustre and a perfect {001} cleavage and occupy fractures and cavities in carbonate vugh…
A new hybrid device composed of a magnetostrictive amorphous FeSiB film on piezoelectric PZT substrate is described. DC and AC electric fields were applied to the PZT substrate and the magnetic properties of the magnetostrictive film were observed. Both the initial permeability and the coercive field of the film chang…
Abstract Crystallization, melting, and morphology of a thermoplastic polyimide (New‐TPI) containing pyromellitic dianhydride (PMDA) and 3,3'‐bis(4‐aminophenoxy) biphenyl diamine (33BAPB) moieties have been studied. This material showed a glass transition temperature ( T g ) of 250°C, an equilibrium melting temperature…
The influence of the structurally similar additives, o-chloronitrobenzene (o-CNB), p-chloronitrobenzene (p-CNB), p-dichlorobenzene (p-DCB), and p-dinitrobenzene (p-DNB), on the morphology of m-chloronitrobenzene (m-CNB) crystals has been investigated theoretically and experimentally. Both experiments and predictions c…
