    A NEW Pk PHENOTYPE IN THE P BLOOD GROUP SYSTEM (1980)

    Notes: A healthy 22-year-old woman was noted to have erythrocytes of the Pk phenotype: a strong Pk antigen, no detectable P antigen and anti-P antibody in her serum. Her erythrocytes contained four to six times as much Pk glycolipid (globotriaosylceramide or CTH) and approximately half as much P glycolipid (globotertraosylceramide or globoside) as normal red cells. The structures of CTH and globoside were characterized by analysis of permethylated sugars and complement fixation in addition to chromaographic mobility and sugar composition. Inasmuch as the erythrocytes of two Pk individuals that were analysed previously (Marcus et al., 1976) contained no detectable globoside, these abnormalities appear o represent a new phenotype in the P blood group system.

    The influence of water solubility on the movement and degradation of simazine in a fallow soil (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Weed research 24 (1984), S. 0

    Notes: The movement and degradation of simazine in the field during winter and summer were measured and compared with simulations using a simple model. The model only simulated simazine behaviour closely when water solubility was taken into account. Relationships between water solubility, melting point, soil adsorption and octan-1-ol/water partition coefficient indicate that, at agricultural rates of application, water solubility will only have an important influence on behaviour for relatively polar chemicals with high melting points.

    Cervical intraepithelial neoplasia and ‘warty’ atypia: a study of colposcopic, histological and cytological characteristics (1982)
    Oxford, UK : Blackwell Publishing Ltd
    BJOG 89 (1982), S. 0 
    Details
    ISSN: 1471-0528
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Summary. Colposcopic, histological and cytological characteristics of 168 consecutive patients attending a colposcopy clinic were reviewed. A group of patients demonstrated a cluster of histological features previously related to possible human papilloma virus infection of cervical epithelium, including particularly koilocytosis, double nucleation and dyskeratosis. These patients had a significantly greater occurrence of colposcopic ‘finger-like’ lesion outline and colposcopic impression of warty change, but not of other specific colposcopic features. Over two-thirds of patients with histological warty features did not show these colposcopic changes. Cytological changes previously related to warty lesions did not occur commonly, and appeared to underestimate the histological occurrence of such changes. Histological changes considered to represent CIN were uncommon in patients who said that they had begun sexual activity less than 10 years ago, whereas patients with warty characteristics on histology showed no such bias.

    Details
    ISSN: 1471-0528
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Summary. A total of 423 patients with cervical intraepithelial neoplasia (CIN) have been treated with a carbon dioxide laser in the out-patient colposcopy clinic. Thirty patients required two or more treatments. Outcome has been assessed in 408 patients followed for more than 1 year. Sixteen patients (4%) have had a recurrence of CIN. Failures were not related to age, parity or size of lesion.

    Defect characterization in the short-wavelength regime (1980)
    Springer
    Journal of nondestructive evaluation 1 (1980), S. 235-247

    Notes: Abstract The scattering of acoustic waves by different types of spherical defects in a silicon nitride matrix is calculated by using Ying and Truell's scattering theory. The theoretical scattering results are interpreted using a ray tracing approach. Experiments were carried out at a high frequency (150–450 MHz) to characterize defects in silicon nitride. Time and space averaging, Wiener filtering, diffraction, and propagation loss corrections were used to remove the effect of the transducer response and propagation loss in the material from the scattered signal. Our experimental results indicate the presence of a new type of defect in silicon nitride. They give the type and size of voids, cracks, and Si inclusions in good agreement with measurements obtained after sectioning.

    Accept/reject decisions and failure prediction for structural ceramics: Application to failure from voids (1980)
    Springer
    Journal of nondestructive evaluation 1 (1980), S. 37-52 
    Details
    ISSN: 1573-4862
    Keywords: failure prediction ; accept/reject decisions ; ceramic materials ; ultrasonics ; fracture ; probabilistic model ; NDE
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology , Mathematics
    Notes: Abstract A general probabilistic method for reaching accept/reject decisions and failure prediction based on nondestructive evaluation procedures is described. The method is illustrated for ceramic materials that fail by the activation of microcracks located at void surfaces. The inspection procedure used for the analysis is the long wavelength ultrasonic method. The analysis indicates influences on the decision level and on the false-reject probability of variations in the signal-to-noise ratio and in the preexistent void population. The ultrasonic inspection is shown to exert a relatively minor influence on the false-reject probability, even for low signal-to-noise ratios, low stresses, and a widely dispersed void population, because of the intrinsic variability of the selected failure process. More encouraging results concerning the utility of NDE are anticipated to apply to other failure mechanisms in ceramics.

    Probabilistic models for defect initiated fracture in ceramics (1980)
    Springer

    Notes: Abstract Fracture tests on hot-pressed silicon nitride containing voids and several types of inclusion have been conducted. Fracture models pertinent to each defect type have been proposed and correlated with the data. The specificity of the fracture models is emphasized, and the various trends with defect size that result from the models are described. The resultant fracture probability relations are one of the key inputs to accept/reject decisions for nondestructive failure prediction.

    Surface acoustic wave measurements of surface cracks in ceramics (1981)
    Springer

    ISSN: 1573-4862
    Keywords: acoustics ; surface acoustic waves ; Rayleigh waves ; ceramics ; surface cracks ; residual stresses ; crack extension ; NDE

    Notes: Abstract An investigation of scattering from surface cracks has been conducted. In particular, the change in the reflection coefficient of a Rayleigh wave incident on a surface indentation crack has been measured as the sample is stressed to fracture. The acoustic measurements have been correlated with the stable crack extension that precedes final failure. The crack extension behavior of as-indented specimens was found to differ appreciably from that of annealed specimens. Cracks in the annealed samples exhibited partial crack tip closure, but little stable extension, whereas cracks in the as-indented samples displayed both crack closure and irreversible crack growth. This behavior has been rationalized by invoking concepts based upon the residual stresses created by indentation.

    On the mechanical behavior of brittle coatings and layers (1983)
    Springer
    Oxidation of metals 20 (1983), S. 193-216

    ISSN: 1573-4889
    Keywords: Brittle coatings ; residual stress ; spalling ; mechanical failure ; stress relaxation ; buckling
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract This paper examines several important issues concerning the mechanical properties of coatings, films, and layers. Major emphasis has been placed on descriptions of residual stresses and their influence on mechanical failure of the coating. The residual stresses are shown to depend on the details of the coating or oxidation process, the general curvature of the substrate, the waviness of the coating-substrate interface, and the stress relaxation characteristics of the coating. Residual stress-induced coating failures, which consist either of coating fractures or spalling, are described. The latter is usually more serious and has been afforded primary attention. It is shown that spalling of the coating is a consequence of buckling, when the coating is subject to significant residual compression. The conditions needed to induce buckling and subsequent spalling are described.
