    Notes: Abstract Data concerning tooth loss in developing countries may indicate the dental health status in young people and serve as baseline data for evaluation of future dental health programs. The study population consisted of 304 schoolchildren (145 males, 159 females) from Belo Horizonte, M.G. Brazil. The mean age was 14.5, ranging from 13 to 16 yr. The number of teeth already lost and teeth indicated for extraction were assessed from two posterior bitewing radiographs and one frontal color photo which were obtained from all participants. The results showed that 2/3 of the studied population had lost one or more permanent teeth. The average number of missing teeth was 1.8 in both males and females. Of the various teeth, the mandibular first molars had most frequently been lost. Differences between the sexes concerning amount and pattern of lost teeth were small.

    Notes: Early documentation is important in the process of sorting disaster victims. To provide a basis for this documentation, a four category card has been designed that can be rapidly used with little previous training. Once folded, the card displays the category of urgency on one side and basic medical details on the reverse. Later changes of category can easily be effected by refolding the card.

    Notes: The expression of human placental cell surface antigens was examined in cells of lymphoid origin, including peripheral blood lymphocytes and cultured lymphoblastoid cells of bone marrow or thymus derivation. A select group of this. defined set of surface antigens was detected on all three cell preparations. The most remarkable observation was the conspicuous absence of three subunits previously demonstrated to be present on all human cell surfaces examined to date. Antiserum directed against several placental components prevents adhesion and spreading of cell which grow attached to surfaces. These results suggest a role for these three glycoproteins in mediating cellular adhesion.

    Ions in holes: An experimental study of ion distributions inside surface features on radio-frequency-biased wafers in plasma etching discharges (2002)

    Notes: We present an experimental study of ion fluxes, energy distributions, and angular distributions inside surface features on radio frequency-biased wafers in high-density, inductively driven discharges in argon. Specifically, we present data on ion distributions at the bottom of 100-μm-square, 400-μm-deep "holes" in the wafer. Transmission of ions to the bottom of the holes increases with increasing ion energy and decreases as the sheath size becomes comparable to the hole size. Ion energy distributions at the bottom of the holes are narrower than distributions on the flat wafer surface. The flux of ions remains normal to the wafer surface over most of the hole area but the flux of ions within 6 μm of the wall is angled towards the wall. The observed trends are consistent with effects expected due to bowing of the plasma sheath around the surface features on the wafer. Scattering of ions off sidewalls contributes at most, only a small part of the ion flux reaching the bottom of the hole. © 2002 American Institute of Physics.

    Notes: Abstract Recently WHO has launched an index for assessing the periodontal treatment needs of a population in terms of resources required. This Community Periodontal Index of Treatment Needs was applied in 308 Brazilian 15-yr-old schoolchildren from a population with a high prevalence of periodontitis. The results showed that almost all subjects needed some kind of care. Totally, 4133 time units were required. Most of the time needed was for motivation and instruction in oral hygiene, and scaling. Several individuals assigned for complex treatment due to pockets deeper than 5.5 mm showed no signs of radiographic bone loss, and in the cases with bone loss, the lesions were few and small. The CPITN therefore seemed to overestimate the need for treatment in this young population. To overcome this problem, it was suggested that complex treatment should not be included in planning of systematic periodontal care for young populations, and that subjects with time periodontal lesions should be given priority m community programs.

    Prevalence of bone loss in a group of Brazilian teenagers assessed on bite-wing radiographs (1984)

    Notes: Abstract Bite-wing radiographs were used to assess periodontal disease in 304 Brazilian 15-year-old schoolchildren from a population with a low socioeconomic status. The criterion for destructive periodontitis was a distance from the cementoenamel junction to the alveolar crest greater than 2 mm. 90 subjects were excluded, mainly due to missing first molars. Bone loss was diagnosed in 28% of the subjects. More males than females were affected. 50% of all lesions were observed adjacent to first molars. The juvenile periodontitis type of lesion was found in 8 subjects. It was concluded that in young populations bite-wing X-rays seem to be valuable in screening for individuals with incipient bone loss as well as for identification of subjects with juvenile periodontitis. In community programs regular use of this kind of roentgen examination is therefore recommended.

    Notes: Abstract. A multidisciplinary study was made of lakes and lagoons in a thermokarst embayment on Richards Island, Canadian Beaufort Sea, in order to investigate the response of the Mackenzie Delta shoreline to changing hydrological influences. Seismo-acoustic profiles made from an amphibious vehicle, combined with sediment core data, show that the deepest lakes contain up to 10 m of transparent or stratified silty mud overlying the Kittigazuit sand basement. Palynological and microfossil data from 21 surface samples allow delineation of freshwater, saltmarsh, tidal flat and subtidal assemblages. These modern reference data allow distinction of freshwater and marine facies in the cores and subsequent interpretation of geochemical content (carbon, ammonia, sulphate). Radiocarbon dates and 137 Cs show that sedimentation rates have increased by an order of magnitude since drowning of the embayment during the past millennium, and that most of this sediment is from the Mackenzie River plume.

    Notes: Abstract The Lawrence Livermore National Laboratory has developed an extensive quality assurance program to provide high quality data and assessments in support of the Marshall Islands Dose Assessment and Radioecology Program. Our quality assurance objectives begin with the premise of providing integrated and cost-effective program support (to meet wide-ranging programmatic needs, scientific peer review, and build public confidence) and continue through from design and implementation of large-scale field programs, sampling and sample preparation, radiometric and chemical analyses, documentation of quality assurance/quality control practices, exposure assessments, and dose/risk assessments until publication. The basic structure of our radioassay quality assurance/quality control program can be divided into four essential elements: (1) sample and data integrity control, (2) instrument validation and calibration, (3) method performance testing, validation, development and documentation, and (4) periodic peer review and on-site assessments. While our quality assurance objectives are tailored towards a single research program and the evaluation of major exposure pathways/critical radionuclides pertinent to the Marshall Islands, we have attempted to develop quality assurance practices that are consistent with proposed criteria designed for laboratory accreditation.

    Notes: Abstract The United States conducted a series of nuclear tests from 1946 to 1958 at Bikini, a coral atoll, in the Marshall Islands (MI). The aquatic and terrestrial environments of the atoll are still contaminated with several long-lived radionuclides that were generated during testing. The four major radionuclides found in terrestrial plants and soils are cesium-137, strontium-90, plutonium-239+240 and americium-241. Cesium-137 in the coral soils is more available for uptake by plants than 137Cs associated with continental soils of North America or Europe. Soil-to-plant 137Cs median concentration ratios (CR) (kBq·kg-1 dry weight plant/kBq·kg-1 dry weight soil) for tropical fruits and vegetables range between 0.8 and 36, much larger than the range of 0.005 to 0.5 reported for vegetation in temperate zones. Conversely, 90Sr median CRs range from 0.006 to 1.0 at the atoll versus a range from 0.02 to 3.0 for continental silica-based soils. Thus, the relative uptake of 137Cs and 90Sr by plants in carbonate soils is reversed from that observed in silica-based soils. The CRs for 239+240Pu and 241Am are very similar to those observed in continental soils. Values range from 10-6 to 10-4 for both 239+240Pu and 241Am. No significant difference is observed between the two in coral soil. The uptake of 137Cs by plants is enhanced because of the absence of mineral binding sites and the low concentration of potassium in the coral soil. Cesium-137 is bound to the organic fraction of the soil, whereas 90Sr, 239+240Pu and 241Am are primarily bound to soil particles. Assessment of plant uptake for 137Cs and 90Sr into locally grown food crops was a major contributing factor in: (1) reliably predicting the radiological dose for returning residents and (2) developing a strategy to limit the availability and uptake of 137Cs into locally grown food crops.
