Polymeric materials, although they are not volatile themselves, may be analysed by gas chromatography (GC) through the use of analytical pyrolysis. Because the fragmentation pattern produced by heating is reproducible, the pyrolysates provide much information about the original macromolecule of which they were a part.…
In order to evaluate formability of silhouette, drape coefficient obtained from circular specimen has been used.In this study, drape cofficient of lady's dress fabrics which are used mainly for one-piece dress or blouse is measured by FRL drape meter.And relationship between drapability and mechanical properties of fa…
Iridium(II) octaethylporphyrin dimer, [Ir(OEP)]2, has been prepared by photolysis of (OEP)IrCH3 in C6D6 solvent, and found to undergo alkene insertion and oxidative addition of alkyl C–H bonds.
Mixed uranium-plutonium monocarbide (MC) with a controlled amount of mixed sesquicarbide (M2C3) will be used as driver fuel for the first time in the world in the fast breeder test reactor (FBTR) at Kalpakkam, India. The mixed-carbide fuel for the FBTR has been developed on the basis of indigenous resources of plutoni…
The single-crystal X-ray structure of K4H2[P2W21O71(OH2)3]·28H2O [space group P63/mmc, a= 16.295(2), c= 19.771(5)Å, and Z= 2; Mo radiation, R= 0.037 for 1 042 unique data] has been determined and the 183W n.m.r. spectrum of the anion in H2O–D20 has been recorded. The anion has true point symmetry C2v but occupies a D3…

The basicity and Cu(II) ion complexation of polymers containing amino acid residues, carrying a tertiary amino group in the main chain and a carboxylic group as the side-chain substituent, have been studied in aqueous solution by potentiometric, viscosimetric, and spectrophotometric techniques. Both protonation consta…

A dental adhesive resin containing 4-META was bonded to three different surface states, an as-polished surface and two oxidized surfaces, of a 70 mass % Co-Cr alloy. The surface structure of the alloys was analyzed by ESCA and reflection electron diffraction. The relationship between the bonding strength and surface s…
Hydrazinium lanthanide complexes of formula N2H5Ln(SO4)2·H2O, where Ln = La, Ce, Pr, Nd, or Sm, have been prepared and investigated by means of i.r. and electronic spectroscopy, thermal analysis, and magnetic susceptibility measurements. The crystal structure of the neodymium compound has been determined by convention…

The production of an exopolysaccharide (mucin) by some Staphylococcus epidermidis strains facilitates bacterial adhesion to prosthetic vascular grafts and may play an important role in adherence-mediated growth. An in vitro model was developed to measure the differential adherence of mucin-producing (RP-12) and nonmuc…
Description STP 927 presents findings on the durability of mechanically jointed structures. Specifically, this publication contains basic and applied research covering bridge structures, airframes, adhesive bonding, welding and metallic, and composite materials.
The dielectric relaxation of glycerol and n-propyl alcohol in the supercooled liquid state has been investigated at frequencies from 5 Hz to 13 MHz and at pressures up to 1 GPa. The high-pressure dielectric cell and the measurement procedures are described in detail. A significant broadening of the loss peak is observ…
Carbonyl compounds are reduced with trialkoxy-substituted silane to the corresponding alcohols chemo- and stereo-selectively in the presence of alkali metal alkoxide under mild conditions; reduction occurs very smoothly by using an alkoxide derived from pinacol as a bidentate ligand.
The blood concentration and urinary excretion after intravenous injection of liposomes containing 3H-inulin at three dose levels were examined in rats. A pharmacokinetic model for the dose dependency is postulated based on the results. The effects of vesicle size were also examined and the biological disposition was s…
The antiferromagnetic mixed valence manganese complex [Mn6O2(Me3CCO2H)4(Me3CCO2)10] has been prepared by the reaction of MnCO3 with pivalic acid in toluene, and its molecular structure, determined by X-ray methods, comprises the new polynuclear cluster grouping of two tetrahedral oxygen-centred tetramanganeses cluster…
