    Notes: The presence of a low molecular mass polypeptidic antigen in Borrelia burgdorferi was described. The protein was exposed at the bacterial surface since it was clearly identified by mAb 3H4 using the immunofluorescence test performed with living bacteria. This antigen was cleaved by proteinase K treatment, whereas it was resistant to the action of chymotrypsin, trypsin and thermolysin. Western blotting analysis of the immunological reactivity of this antigenic structure performed using monoclonal antibody, mouse-immune ascitic fluids raised against B. burgdorferi and other spirochetes, sera from patients with Lyme disease and other infirmities in which false positive results in serological tests for B. burgdorferi have been described, demonstrated that this protein expresses only species-specific epitopes which may be recognized during human B. burgdorferi infections.

    Problems in assessing macroseismic intensity from historical earthquake records (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Terra nova 5 (1993), S. 0

    ISSN: 1365-3121

    Notes: This paper tackles the problems connected with the use of macroseismic scales, with particular attention to MSK. Intensity estimates are in principle affected by uncertainties which are seldom quantified in practice. In the case of two localities (Scisciano and Orciano) damaged by two Italian earthquakes (1741, Fabriano and 1846, Orciano), which have a good historical documentation, the difficulties of obtaining the data necessary for MSK evaluation have been analysed. In order to assess the maximum range of uncertainty the data have been analysed in two extreme scenarios. Finally a comparison between intensity assigned using the MSK and MCS scales is analysed.

    The effect of bead diameter on the accuracy of two current techniques used to quantify bone ingrowth in porous-coated implants (1994)

    Notes: The effect of the bead diameter on the accuracy of two techniques used in bone ingrowth quantification, microradiography and backscattered electron imaging-scanning electron microscopy (BEI-SEM), was assessed using porous-coated implants. Two groups of seven titanium porous implants (group A: bead size 250–350 μm and group B: 500–700 μm) were implanted for 12 weeks in a canine model. After euthanasia, the same histological slides were prepared for microradiography and BEI-SEM. The percentage of bone, bone ingrowth, bone ongrowth, porosity and bone index were determined by a point counting method using images from both techniques. ANOVA and Tukey's test were used to compare the results from the different bead sizes and techniques. The results showed significant higher bone ingrowth in microradiography groups, and significant lower porosity in only the fine-bead microradiography group (group A size). Microradiography also obtained significantly higher bone ongrowth, but only for the coarse bead size group (group B). From these results it was concluded that microradiography decreases the porosity of the porous coating compared with BEI-SEM. This effect seems to be dependent on the bead diameter. The smaller the diameter, the greater the effect. Furthermore, microradiography increases bone ingrowth which seems to be affected independently of the bead diameter, becoming the most sensitive parameter to increase.

    Bone ingrowth analysis and interface evaluation of hydroxyapatite coated versus uncoated titanium porous bone implants (1994)
    Springer

    Notes: Fourteen titanium porous-coated implants with a cylindrical shape (length 22 mm and diameter 5±0.3 mm) were prepared. Bead size was 250–350 μm. Seven implants were plasma-sprayed with hydroxyapatite and the other seven remained uncoated. Implants, both hydroxyapatite-coated and uncoated, were randomly selected and press fitted longitudinally into the proximal femoral cancellous bone bilaterally in seven dogs. After 12 weeks the dogs were euthanized and push-out and histomorphometric backscattered electron microscopy studies were carried out. No statistical differences in the mechanical tests were observed. Comparing hydroxyapatite-coated versus uncoated implants, the histomorphometric results showed statistical significance in the percentage of bone (p=0.01); and in bone index, ratio between bone ingrowth and bone ongrowth (p=0.01). The size of the bone implant interface was smaller in the hydroxyapatite applied to spherical bead titanium porous coatings were demonstrated. These morphological and histomorphometric results support the concepts involved with the use of hydroxyapatite as a coating for uncemented porous prosthetic devices.

    Fragmentation of gold projectiles: From evaporation to total disassembly (1991)

    Notes: Abstract We have studied the fragmentation of Au projectiles interacting with targets of C, Al and Cu at an incident energy ofE/A=600 MeV. The employed inverse kinematics allowed a nearly complete detection of projectile fragments with chargeZ≧2. The recorded fragmentation events were sorted according to three observables, the multiplicityM lp of light charged particles, the largest atomic numberZ max within an event, and a new observable,Z bound, representing the sum of the atomic numbersZ of all fragments withZ≧2. Using these observables, the impact parameter dependence of the fragmentation process was investigated. For all three targets, a maximum mean multiplicity of 3 to 4 intermediate mass fragments (IMFs) is observed. The corresponding impact parameters range from central collisions for theC target to increasingly peripheral collisions for the heavier targets. It is found that the correlation between the IMF multiplicity andZ bound, extending from evaporation type processes (largeZ bound) to the total disassembly of the projectile (smallZ bound), is independent of the target nucleus. This universal behaviour may suggest an — at least partial — equilibration of the projectile fragment prior to its decay.

    An approach for the processing engineer: Rheotechnics (1974)

    Notes: Processing involves complex polymer flow problems, either in the melt or in solution. Rheologists have developed many studies with the aim of correlating polymer structure with flow properties and polymer processing. Most of these studies, however, have had relatively little impact on practical processing because of the difficulty in solving the mathematical equations involved. Recently, a relatively few papers have been published with the aim of bridging the gap between theoretical rheology and technology. The first part of the paper presents an account of works which have dealt with the process of filling a mold cavity. The second part discusses briefly some experimental results which provide a correlation between moldability and rheological properties. By analogy with the terms “electrology” and “electrotechnics,” the term “rheotechnics” is suggested for this new area of study.
