Dieta de Micoureus demerarae (Thomas) (Mammalia, Didelphidae) associada às florestas contíguas de mangue e terra firme em Bragança, Pará, Brasil Diet of Micoreus demerarae (Thomas) (Mammalia, Didelphidae) associated with contiguous forests of mangrove and terra firme in Bragança, Pará, Brazil

A dieta de Micoureus demerarae (Thomas, 1905) foi estudada em bosques de mangue e terra firme através de amostras estomacais e fecais. O número de indivíduos capturados foi inversamente proporcional à disponibilidade de frutos e insetos, sendo Coleoptera e Hemiptera as ordens de artrópodes mais consumidos e Passifloraceae e Arecaceae os frutos mais ingeridos. Desse modo, tanto a maior variabilidade de frutos como a alta produção destes durante a estação seca, parecem explicar o aumento da captura desses animais nos bosques de terra firme, dos quais são originalmente provenientes. Os itens alimentares sugerem que esta espécie possui uma dieta do tipo onívora, independentemente da sazonalidade ou distribuição dos recursos disponíveis.<br>The diet of Micoureus demerarae (Thomas, 1905) was studied in mangrove and terra firme stands by using stomachal and faecal samples. The number of captured individuals was inversely proportional to availability of fruits and insects, being Coleoptera and Hemiptera the most consumed arthropod orders and Passifloraceae and Arecaceae the most ingested fruits. Thus, either fruits variability or their high yield during the dry season seem to explain the increase of captured animals in the terra firme stands, where they originally come from. The food items suggest that this species has an omnivorous diet, independently of the seasonality or distribution of available resources

Criticism and Conversational Texts: Rhetorical Bases of Role, Audience, and Style in the Buber-Rogers Dialogue

This essay describes conversation as an ensemble accomplishment that can be illuminated by critics working with specific texts within a rhetorical framework. We first establish dialogue as the key concept for any criticism of conversation, specifying the rhetorical dimensions of interpersonal dialogue. Second, we show how template thinking is particularly dangerous for conversational critics and suggest a research (anti)method, based on a coauthorship, that provides a thoroughgoing dialogical access to texts. Finally, we exemplify dialogic criticism of a conversational text by analyzing the famous 1957 dialogue of philosopher Martin Buber and psychologist Carl Rogers

A correlation for heat of vaporization of pure compounds

Twenty-seven selected equations were tested on 162 compounds with 1958 calorimetric data for their abilities to reflect the temperature influence on the heat of vaporization of pure compounds. A new equation is recommended (overall percent deviation 0.27% and percent deviation 0.59% above 0.9T(r))

Storage ring at HIE-ISOLDE: technical design report

We propose to install a storage ring at an ISOL-type radioactive beam facility for the first time. Specifically, we intend to setup the heavy-ion, low-energy ring TSR at the HIE-ISOLDE facility in CERN, Geneva. Such a facility will provide a capability for experiments with stored secondary beams that is unique in the world. The envisaged physics programme is rich and varied, spanning from investigations of nuclear ground-state properties and reaction studies of astrophysical relevance, to investigations with highly-charged ions and pure isomeric beams. The TSR might also be employed for removal of isobaric contaminants from stored ion beams and for systematic studies within the neutrino beam programme. In addition to experiments performed using beams recirculating within the ring, cooled beams can also be extracted and exploited by external spectrometers for high-precision measurements. The existing TSR, which is presently in operation at the Max-Planck Institute for Nuclear Physics in Heidelberg, is well-suited and can be employed for this purpose. The physics cases as well as technical details of the existing ring facility and of the beam and infrastructure requirements at HIE-ISOLDE are discussed in the present technical design report
