Cultural Aspects of a Patient\u27s Symptomatology: A Case Report
Culture influences numerous aspects of human experience including behavior, beliefs, values and attitudes. A case report is presented emphasizing how cultural manifestations of a psychiatric illness may materially affect presentation of symptoms, illness perception, and explanatory model of illness of a patient. Cultural background is explored to offer improved rapport and patient care
Red-Winged Blackbirds: II. Pigmentation in Epaulets of Females
Author Institution: Put-in-Bay, OH 43456This study describes color changes in upper secondary coverts (epaulets) of female red-winged blackbirds (Agelaius phoeniceus) in successive molts. The methods used included Munsell color chips and microscopic examination of feathers. Examination of feathers collected from these upper secondary coverts showed color pigments distributed in barbs and barbules of distal feathertips. Yellow pigments predominated in juvenile and first-winter females and orange and rust in secondwinter and older birds. Rust color resulted from dark hamuli on orange barbules; in the absence of melanin in hamuli the feather appeared orange. No appreciable color changes appeared after the second winter plumage. Females with pure red feathers were not found among the redwings studied. Effect of diet on pigmentation could not be ascertained by the methods used

First measurement of polarisation transfer in deuteron photodisintegration
A first measurement of the polarisation transfer from a circularly-polarised photon to the final state neutron (Cx′n role= presentation style= box-sizing: border-box; margin: 0px; padding: 0px; display: inline-block; line-height: normal; font-size: 14.4px; word-spacing: normal; overflow-wrap: normal; text-wrap: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; position: relative; \u3e��′�) in deuterium photodisintegration has been carried out.

Photoproduction of the meson on the proton at large momentum transfer
The differential cross section, for meson exclusive
photoproduction on the proton above the resonance region ( GeV) was
measured up to a momentum transfer GeV using the CLAS detector at
Jefferson Laboratory. The channel was identified by detecting a proton
and in the final state and using the missing mass technique. While the
low momentum transfer region shows the typical diffractive pattern expected
from Pomeron and Reggeon exchange, at large the differential cross section
has a flat behavior. This feature can be explained by introducing quark
interchange processes in addition to the QCD-inspired two-gluon exchange.Comment: 5 pages, 5 figure
