    Notes: 16 , 1671 (1991)] described a Nd:YLF APM laser which somehow automatically adjusted the relative resonator phase. We reproduce this behavior and analyse its origin. Thermal effects due to the light power guided in the fiber affect the effective fiber length, which in turn influences the phase and thus the power level; hence a closed servo loop results. We demonstrate this explanation to be correct in quantitative terms. Consequences arise for other systems involving fiber-optic loops or interferometers.

    Percutaneous ethanol injection into parathyroid adenomas: mid- and long-term results (1998)

    Notes: Abstract. The aim of this study was to evaluate mid- and long-term results of ultrasonically guided ethanol injection into parathyroid adenomas. From 1988 to 1996, 27 patients (mean age 77 ± 13 years) were treated for parathyroid adenomas by percutaneous ethanol injection. The survey included clinical information, plasma calcium, phosphorus and PTH (1–84) evaluation. Follow-up lasted 22.6 ± 10 months. No major complications were observed for 63 ethanol injections. Biochemical recovery was 58 %, biochemical improvement at 3 months was 33 %, and failure was 7 %. Four of 15 cured patients presented a recurrence of the disease 1 or 2 years after the first treatment. Ultrasonically guided ethanol injection can be useful in the treatment of parathyroid adenomas when surgery is not possible. The immediate results are interesting but not as good as those obtained with surgery. A regular biochemical survey is necessary so that recurrences can be recognized and treated at an early stage.

    Race differences in response to combat stress (1990)
    Springer
    Journal of traumatic stress 3 (1990), S. 379-393

    ISSN: 1573-6598

    Notes: Abstract A number of authors have written poignantly about the Black experience in the Vietnam war; however, very little research has addressed this topic. The present report studied race differences in preservice, stressor, and outcome variables in a community sample of 181 war veterans. Blacks reported higher levels of stressors and outcome, particularly for PTSD-related symptoms. The results suggested that the relationship between stressors and outcome can be defined by a common regression line for Blacks and Whites, and that the high symptom levels observed for Blacks in the sample were accounted for by higher levels of stressors during their war experience. The cognitive coping mode of avoidance did not conform to this pattern and showed higher levels for Blacks even controlling for other factors. Potential cultural origins of this difference were noted.
