    Evaluation of the bonding of cervical restorative materials (1982)

    Topics: Medicine
    Notes: Variable results have been reported for the bonding of cervical lesion restorative materials to enamel and dentine. The effect of surface condition on bond strength was studied for two glass ionomer and one polycarboxylate cements and one composite resin material.Flat surfaces of human enamel and dentine, prepared by wet grinding on 600 grit silicon carbide paper, were treated respectively with water, phosphoric acid, citric acid, EDTA and/or remineralizing solution. Using an improved bonding device the cements and the composite resin were bonded to the prepared enamel and dentine surfaces. After 24 h in water at 37°C a tensile bond strength was determined. The bond fracture surfaces were examined in the scanning electron microscope. The results showed good bonding of the materials to enamel after the recommended surface treatments with cohesive failure and values 60–120 kg/cm2Bonding to dentine was more variable and was critically dependent on surface preparation.Caulk-ASPA bond strengths that were obtained after various treatments ranged from 34 kg/cm2 (untreated dentine) to 54 kg/cm2 (citric acid treatment).Fuji ionomer bond strengths that were obtained after various treatments ranged from 42 kg/cm2 (citric acid treated dentine) to 56 kg/cm2 (EDTA treated).Durelon bond strengths that were obtained after various treatments ranged from 24 kg/cm2 (citric acid treated dentine), to 69 kg/cm2 (remineralizing solution treated dentine).The bond strengths that were obtained with Cervident after various treatments ranged from 0 kg/cm2 (untreated dentine) to 30 kg/cm2 (phosphoric acid treated dentine plus the adhesion promoter).SEM examination showed micromechanical bonding through penetration into dentinal tubules for all materials.

    THE INFLUENCE OF PERMEABILITY ON COMPRESSIONAL WAVE VELOCITY IN MARINE SEDIMENTS (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical prospecting 30 (1982), S. 0 
    Details
    ISSN: 1365-2478
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences , Physics
    Notes: To investigate the effect of permeability on the propagation of seismo-acoustic waves through marine sediments, a theoretical model based on Biot's equations is established which relates the compressional wave velocity measured at a fixed frequency to computed velocities at zero and infinite frequencies in terms of sediment porosity and permeability. The model is examined experimentally in a standard soil mechanics consolidation test (itself dependent, among other things, on sediment porosity and permeability) which has been modified to include measurements of compressional wave velocity at 1 MHz and shear-wave velocity at 5 kHz. This test allows the elastic modulus of the sediment frame to be assessed under different load conditions simultaneous with the velocity determinations.From a number of tests on different samples, five samples are chosen to typify the range of sediment sizes. The results show that the difference between the measured velocity at 1 MHz and the model-derived velocity at zero frequency increases with increasing particle size (from clays to fine sand), with decreasing porosity, and with increasing permeability. For sediments coarser than fine sand the simple model breaks down, possibly because of the dominance of scattering/diffraction effects at the high frequency of the experiment. Within this limitation the model seems satisfactory to offer a capability of predicting the permeability of a sea floor sediment to an order of magnitude by the in situ measurement of seismic velocities over a wide range of frequencies; the prediction process requires a good in situ determination of sediment porosity such as that offered by electrical formation factor measurements.

    Effect of Steam Temperature, Speed of Cooling and Cutin Disruption in Steam and Lye Peeling of Apples (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 47 (1982), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005

    Notes: A laboratory model steam peeler was adapted to accept superheated steam and direct injection of cold water in order to study the effect of rapid heating with superheated steam and rapid cooling under partial vacuum on the peeling efficiency of‘Red Delicious’apples. A test was also designed to determine the effect of physical disruption of the cutin layer on the efficiency of caustic peeling. Steam peeling resulted in higher peeled yields and brighter product color than caustic peeling. The peeled yields were 97.5% for superheated steam-peeled apples with flash cooling, 91.7% for caustic peeled fruit which had a prepeel treatment to physically disrupt the cutin layer, 85.8% for conventionally caustic-peeled fruit, and 82.7% for the mechanically peeled control.

    Improved Aseptically Filled Sweet Potato Purees (1982)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: A high quality sweet potato puree with better color stability than frozen purees was produced by flash sterilization followed by aseptic packaging. Starch conversion time was shortened by slicing the sweet potatoes and accurately controlling the temperature during conversion. Processing of inoculated purees for 13 sec at 138°C followed by aseptic filling was adequate for commercial stability. The effect of several processing variables on puree and sweet potato souffle quality was examined. Improved quality and storage stability of sweet potato purees were accomplished by flash sterilization at very high temperatures followed by aseptic packaging.

    Polymorphism in silver thiocyanate: preparation of a new phase and its chaacterization by X-ray powder diffraction (1982)

    Notes: A new crystalline phase of silver thiocyanate, AgSCN, has been prepared in the presence of gelatin. X-ray powder diffraction data were indexed for an orthorhombic cell with a = 4.083 (1), b = 7.043 (1), c = 11.219 (2) Å, Z = 4. The crystal structure was solved and refined in Pmnn to RF = 0.11 from 54 peak-height powder intensities. Strongly bonded, approximately linear AgNCS units [Ag–N = 2.00(5) Å] are joined together into a three-dimensional polymeric network by three long Ag–S bonds [2.70(2), 2 × 2.64(1) Å]. The configurations at both Ag and S are intermediate between tetrahedral and trigonal pyramidal.
