A three-dimensional covalent network of N atoms possessing a fraction (${\mathit{n}}_{\mathit{r}}$/N) of r-fold-coordinated atoms will, in general, display percolation of rigidity at an average coordination number 〈r〉=2.4-0.4(${\mathit{n}}_{1}$/N), where ${\mathit{n}}_{1}$/N represents the fraction of onefold-coordina…
Abstract A new, well-ordered, thermally robust ethylene glycol intercalate of kaolinite was formed by refluxing the dimethyl sulfoxide intercalate of kaolinite (Kao-DMSO) with dry ethylene glycol (EG). This new phase (Kao-EG 9.4 Å) which is characterized by a d 001 of 9.4 Å is distinct from a previously reported ethyl…

Transparent conducting cadmium oxide (CdO) films have been deposited by spray pyrolysis. The film thicknesses have been determined using Rutherford backscattering spectrometry. X-ray diffraction measurements show that the films are polycrystalline with a preferential orientation along the (111) diffraction plane and t…

This unit describes the procedure for subcloning the sequence encoding the protein of interest into an maltose-binding protein (MBP) vector, and expressing and purifying the fusion protein from the cytoplasm. MBP vectors include a sequence that encodes the four-amino-acid recognition site for the specific protease fac…
In analogy with the well-known theory for fluids a van der Waals theory for solids is proposed. It is shown that, in agreement with recent predictions, the competition between the van der Waals loop of the fluid and the van der Waals loop of the solid can produce three different types of phase diagrams for a simple fl…
Novel polycarbonate (PC) foams with bubbles on the order of 10 μm and cell nucleation densities between 1 and 10 billion cells per cubic centimeter of foam have been produced using carbon dioxide as the blowing agent. The size and number of bubbles can be controlled to produce a wide range of foam densities. This pape…
The unabridged data used in preparing ICRP Publication 38 (1983) and a monograph of the Medical Internal Radiation Dose (MIRD) Committee (Weber et al. 1989) are now available in electronic form. The "ICRP38 collection" contains data on the energies and intensities of radiations emitted by 825 radionuclides (those in I…
Abstract Five different polyaniline salts have been prepared by chemical polymerization of aniline in aqueous solution of different acids. Polyaniline samples have been heat treated at four different temperatures (150, 200, 275, and 375°C) and characterized by electron paramagnetic, electronic absorption, and infrared…

Effects of tranilast, N-(3,4-dimethoxycinnamoyl)anthranilic acid, on collagen synthesis in cultured human skin fibroblasts were studied. Tranilast was found to inhibit collagen synthesis in a dose-dependent manner to a maximum of 55% at 300 microM during 48 h of treatment; the synthesis of type I and type III collagen…
