    Confocal theta microscope with three objective lenses (1994)

    Notes: A microscope using three water immersion objective lenses which realizes confocal, 4Pi-confocal and various confocal theta microscopies in fluorescence, transmission, scattered, and reflection mode is described. An argon-ion laser is the primary light source. A pulsed titanium-sapphire laser allows two-photon absorption fluorescence microscopy. The instrument has a predicted resolution of 100 nm along the illumination axis and a three-dimensional resolution of 5×106 nm3 for lenses each with a numerical aperture of 0.75. This is an improvement of an order of magnitude over a confocal fluorescence microscope using the same lens. Applications of the microscope range from observation of a sample at three different angles, to confocal theta fluorescence microscopy with multiphoton absorption. Since mounting and immersion media are identical, aberrations become negligible. The large working distance of 2 mm makes the instrument ideal for the observation of biological samples of up to 1.5 mm in diameter such as drosophila embryos.

    Studies on Etiologic Factors in Pemphigus (1976)

    Notes: A survey of 234 cases of pemphigus yielded three observations which suggest that different forms of pemphigus may have different etiologies.1. While the incidence of pemphigus in the age group of 21 and over was essentially the same in males and females (108 and 113) the incidence was significantly higher in females in the age group under 20. Only two of 13 patients in this group were males. Also pemphigus foliaceus and erythematosus was reported in a significantly higher proportion of the cases in the age group of 2 1/2 to 20 thus suggesting that the juvenile form of the discase differs from the adult form.2. In four of a group of 15 cases identified as pemphigus foliaceus the disease appeared to be provoked by minor physical insults, a frequency which is significantly higher than the five cases with similar histories in the group of 198 cases identified as pemphigus vulgaris.3. In the entire group of 234 cases two patients with pemphigus both proven by immunofluorescence had relatives with pemphigus. Also a third patient had a blood relative with bullous pemphigoid. This frequency of three per 234 is higher than would be expected by chance. Studies of one family (not included in this survey) with multiple skin antibodies suggest that such familial predispositions may be due to abnormal immune responses.

    Westergaard stress functions for displacement-prescribed cracks-II. Extension to mixed problems (1994)

    Notes: Abstract The single stress functions approach of Westergaard has often been conveniently used for a certain class of stress-prescribed crack problems. In the previous study, the Westergaard approach was successfully extended to displacement-prescribed crack problems. In this paper, the approach was further extended to the combined problem of displacement-prescribed cracks and stress-prescribed cracks. The method developed in the present paper simplifies the analysis of the mixed problem of interest. Several simple examples were discussed in detail to demonstrate the effectiveness of the method presented.
