    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.

    Chondroblastoma: A clinical and radiological study of 104 cases (1985)

    Notes: Abstract The clinical and radiographic findings in 104 patients with chondroblastoma are presented. Pain was an almost constant presenting complaint, often accompanied in the case of para-articular lesions by impaired function of an adjacent joint. The majority (80%) were in long bones with a mean age of presentation of 16 years. The characteristic radiological image of these lesions was an eccentric radiolucency, having a sharply defined sclerotic margin and containing areas of calcification in approximately a third of cases. They were always related to a growth plate. Nearly half were confined to the affected epiphysis or apophysis itself, but most of the remainder had traversed the growth plate to involve also the adjacent metaphysis. The bones around the knee and the proximal ends of the humerus and femur were the sites of predilection. A minority (20%) affected flat bones and short tubular bones of the hand and foot, with a peculiar affinity for the calcaneus and talus. The mean age of presentation of these was 28 years. The radiological pattern was similar, except for a greater tendency to expand the affected bone. Complications included the formation of a secondary aneurysmal bone cyst in 16 cases (10 of them in long bones), one malignant chondroblastoma, and one fibrosarcoma developing after radiation of the original chondroblastoma.

    Long-term coping with combat stress (1988)

    Notes: Abstract The present report examined ongoing patterns of coping in Vietnam combat veterans from community, outreach, and treatment samples. After reviewing various schemas for conceptualizing coping which exist in the literature, seven coping strategies empirically derived from the Horowitz Coping Inventory were described. Results indicated that the modes of coping most associated with combat intensity were the same as those associated with more symptomatology and a clinical diagnosis of PTSD in the present: event processing, time out for reflection, religion, and denial. Veterans who improved in short-term therapy for PTSD, on the other hand, used emotional expression and sublimation strategies. The findings were discussed in terms of the disorder of PTSD, the recovery process, and conceptual models of adaptation to stress.
