Comparative morphological study of the Neotropical Cleomenini genera and their transference to the tribes Rhopalophorini Blanchard and Rhinotragini Thomson (Coleoptera, Cerambycidae, Cerambycinae)

In order to investigate the affinities of the hitherto considered Neotropical Cleomenini genera, a detailed morphological comparative study was carried out based on representatives of their type species and other congeneric species. The results, when compared with representatives of Cleomenes Thomson and other non Neotropical Cleomenini genera together with representatives of Rhopalophorini Blanchard and Rhinotragini Thomson, show that: 1) Listroptera Audinet-Serville, 1834, Dihammaphora Chevrolat, 1859, Haenkea Tippmann, 1953, Aguassay Napp & Mermudes, 2001 and Timabiara Napp & Mermudes, 2001 form a very homogeneous group, not related to other Cleomenini, but sharing several synapomorphies with the Rhopalophorini; therefore they are herein transferred to this tribe; 2) the affinities of Dihammaphoroides Zajciw, 1967, were not clearly defined, needing further investigations; nevertheless, the genus is tentatively included in Rhopalophorini due to its morphological similarity with Dihammaphora and allied genera; 3) Pandrosos Bates, 1867 is brought back to Rhinotragini, in which it was originally placed. Therefore, the tribe Cleomenini Lacordaire is no longer represented in the New World.

Desenvolvimento pós-embrionário de Pattonella intermutans (Thomson) (Diptera: Sarcophagidae) em diferentes dietas

A proposta deste estudo foi de avaliar o desenvolvimento pós-embrionário de Pattonella intermutans (Thomson, 1869) em dietas artificiais preparadas com agar-agar. Dieta D1: leite em pó integral + fermento biológico; Dieta D2: leite em pó integral + fermento biológico + caseína; Dieta D3: leite em pó integral + ovo cru; Dieta D4: carne bovina moída (dieta controle). A carne bovina moída foi a dieta mais eficiente (peso larval de 195,63 mg e viabilidade de neolarva a adulto de 86,5%), quando comparada com as dietas artificiais. Os seguintes resultados foram obtidos para o grupo experimental: Dieta D3: 180,15 mg e 63,5%; Dieta D2: 141,07 mg e 61% e na Dieta D1: 147,98 mg e 51,5%.

O médico George Thomson e os primeiros desenvolvimentos do conceito de gás

The word gas was coined by the "chemical philosopher" Joan Baptista Van Helmont (1579 -- 1644) to name a very broad concept in his chemico-medical system. Eventually, some physicians who followed Helmontian ideas adopted the concept. The present paper aims to analyze the reception of the original idea of gas by an English Helmontian physician, George Thomson (1619 -- 1677). Thomson wrote that the "material cause" of the plague was a gas, and compared it to the "Gas of sulphur". He also related the human archeus to a gas, and explained some observations in the laboratory in terms of production of gases. We observe, however, that Thomson was not as interested as Van Helmont in discussing details about the structure of the matter. Thus, gas did not have the same relevance in Thomson's work as it had in Van Helmont's.

Compton scattering tomography for agricultural measurements

This paper presents a new approach in tomographic instrumentation for agriculture based on Compton scattering, which allows for the simultaneous measurements of density and moisture of soil samples. Compton tomography is a technique that can be used to obtain a spatial map of electronic density of samples. Quantitative results can be obtained by using a reconstruction algorithm that takes into account the absorption of incident and scattered radiation. Results show a coefficient of linear correlation better than 0.81, when comparison is made between soil density measurements based on this method and direct transmission tomography. For soil water contents, a coefficient of linear correlation better than 0.79 was found when compared with measurements obtained by time domain reflectrometry (TDR). In addition, a set of Compton scatter images are presented to illustrate the efficacy of this imaging technique, which makes possible improved spatial variability analysis of pre-established planes.
