Allergy receptor pictured.

were implanted s.c. into the rat thigh. NMR T, values of the adjacent normal muscle, resulting from local inflammatory reactions or from malignant invasion, were measured. Elevations in T, of the underlying muscle occurred within 24 h in both experiments, and it is believed these were caused by rapid inflammatory and immunological reactions to the implants. However the T, values of muscle sampl...

Reference Frames and 3-D Shape Perception of Pictured Objects: On Verticality and Viewpoint-From-Above

Research on the influence of reference frames has generally focused on visual phenomena such as the oblique effect, the subjective visual vertical, the perceptual upright, and ambiguous figures. Another line of research concerns mental rotation studies in which participants had to discriminate between familiar or previously seen 2-D figures or pictures of 3-D objects and their rotated versions....

Affectivity as a factor in the apparent size of pictured food objects.

"Perceptual distortion" of need-related objects has been the concern of many recent studies (1, 2, 3, 4, 7, 8, 9). In addition to the methodological flaws found in many of these studies which were pointed out by Gilchrist and Nesberg (4), they have, almost without exception, reported results based upon differences in the perceived size of various objects between or among groups separated on the...

Characterization of the geometry and topology of DNA pictured as a discrete collection of atoms.

The structural and physical properties of DNA are closely related to its geometry and topology. The classical mathematical treatment of DNA geometry and topology in terms of ideal smooth space curves was not designed to characterize the spatial arrangements of atoms found in high-resolution and simulated double-helical structures. We present here new and rigorous numerical methods for the rapid...
