High Voltage Electron

Mature human dental enamel has presented investigators with several difficulties in ultramicrotomy of specimens for electron microscopy due to its high degree of mineralization. This study explores the possibility of combining ion-milling and high voltage electron microscopy as a means of circumventing the problems of ultramicrotomy.A longitudinal section of an extracted human third molar was ground to a thickness of about 30 um and polarized light micrographs were taken. The specimen was attached to a single hole grid and thinned by argon-ion bombardment at 15° incidence while rotating at 15 rpm. The beam current in each of two guns was 50 μA with an accelerating voltage of 4 kV. A 20 nm carbon coating was evaporated onto the specimen to prevent an electron charge from building up during electron microscopy.

The Relationship

We examined the relationship between texture responses (T) on the Rorschach and adult attachment in the Japanese population. 47 Japanese undergraduate and graduate students (mean age = 20.16, SD = 1.87) completed a self-report adult attachment scale as well as the Rorschach. An ANOVA revealed that T = 1 participants were attached more securely than were other groups. T > 1 participants were more preoccupied with attachment and scored higher on an attachment anxiety scale than the T = 1 group. Although these results were consistent with the interpretation of the texture response according to the Comprehensive System (CS), the results obtained for T = 0 participants were inconsistent with hypotheses derived from the CS. T = 0 participants were high on preoccupied and attachment anxiety scores, although they were theoretically expected to be high on dismissing or attachment avoidance. These results indicated that – at least in Japan – T should be regarded as a sensitive measure of attachment anxiety.
