Consists of seven account books kept by Dr. Sylvester Woodbridge (1754-1824) from 1792 until his death containing entries that record charges for medical visits and administration of medicines, and sales of sundry and grocery items, as well as occasional personal notes and the names of Woodbridge's apprentices and their participation in his Southampton, Massachusetts, medical practice. Woodbridge's methods of treatment were typical for the era: he most commonly prescribed vomits and purgatives for patients. Volume 6 contains loose pages and letterbooks tucked in related to accounting and to the amount and type of wood Woodbridge was buying for his house, and papers dated after his death.

We extend the Jacobson's Coordinatization theorem to Jordan superalgebras. Using it we classify Jordan bimodules over superalgebras of types Q(n) and JP(n), n >= 3. Then we use the Tits-Kantor-Koecher construction and representation theory of Lie superalgebras to treat the remaining case Q(2).

Although texts and wall paintings suggest that bees were kept in the Ancient Near East for the production of precious wax and honey, archaeological evidence for beekeeping has never been found. The Biblical term ""honey"" commonly was interpreted as the sweet product of fruits, such as dates and figs. The recent discovery of unfired clay cylinders similar to traditional hives still used in the Near East at the site of Tel Rehov in the Jordan valley in northern Israel suggests that a large-scale apiary was located inside the town, dating to the 10th-early 9th centuries B.C.E. This paper reports the discovery of remains of honeybee workers, drones, pupae, and larvae inside these hives. The exceptional preservation of these remains provides unequivocal identification of the clay cylinders as the most ancient beehives yet found. Morphometric analyses indicate that these bees differ from the local subspecies Apis mellifera syriaca and from all subspecies other than A. m. anatoliaca, which presently resides in parts of Turkey. This finding suggests either that the Western honeybee subspecies distribution has undergone rapid change during the last 3,000 years or that the ancient inhabitants of Tel Rehov imported bees superior to the local bees in terms of their milder temper and improved honey yield.

The Jordan-Wigner fermionization for the one-dimensional Bariev model of three coupled XY chains is formulated. The L-matrix in terms of fermion operators and the R-matrix are presented explicitly. Furthermore, the graded reflection equations and their solutions are discussed.

Espécies de Apiaceae dispõem de óleos essenciais, nos quais podem ocorrer compostos voláteis, que funcionam como sinais para atração e manutenção de inimigos naturais nas áreas cultivadas. Com base nestas características, este trabalho objetivou avaliar a atratividade aos adultos do predador Chrysoperla externa. Foram utilizados folhas e caules de coentro, endro e erva-doce, coletados aos 30 e 60 dias após a semeadura. As plantas foram dispostas em olfatômetro de quatro vias (formato de "X") disponibilizando-se os odores para machos e fêmeas, virgens e acasalados, em testes de livre escolha. Ao serem liberados individualmente no interior do olfatômetro, foram cronometrados cinco minutos e contabilizado o tempo total de permanência do inseto em cada braço do aparelho. Os dados foram analisados pelo teste c², com frequência esperada de 25%. Estudou-se o rendimento de óleo essencial das três espécies de plantas, 30 e 60 dias após a semeadura, utilizando-se do método de hidrodestilação. A composição química dos óleos foi determinada por cromatografia gasosa acoplada a espectrômetro de massas. Verificou-se que adultos virgens têm preferência por plantas de coentro, enquanto os acasalados preferem plantas de erva-doce, ambas coletadas aos 30 dias. Plantas com 60 dias não proporcionaram resposta atrativa aos adultos de C. externa. O rendimento de óleo tendeu a aumentar com o desenvolvimento fenológico da planta. A composição química do óleo de coentro revelou, como componentes majoritários, o (2E)-decenal e decanal e, para erva-doce, a maior concentração foi de (E)-anetol.
