Anatomical description of the aortic arch of a rare species “the giant armadillo” (Priodontes maximus; Kerr, 1792)

The giant armadillo (Priodontes maximus) is found in diverse habitats from South America. A female adult giant armadillo with a body mass of 45 kg was used. The animal was a victim of trampling on highway AC-40, at 70 km, near the municipality of Capixaba-Acre and the corpse donated to the Animal Anatomy Laboratory at Federal University of Acre (UFAC). The arterial system was filled with natural latex via the thoracic aorta in a direction opposite the blood flow to facilitate the description of the aortic arch and its side branches. The study was approved by CEUA/UFAC – no. 053/2015 and SISBIO no. 47124-1. The aortic arch issued side groups, which had the following sequence: brachycephalic trunk, left carotid artery, left subclavian artery. The brachycephalic trunk forked forming the right subclavian artery and the right common carotid artery. The arrangement allowed the whole carotid blood supply to the brain and surrounding structures present in the animal’s head. The subclavian arteries, of homologous way, originated the arteries: vertebral, thoracic, and cervical costocervical trunk. The aortic arch armadillo showed the same pattern as that described for the Euphractus sexcinctus and different from those reported for the Dasypus novemcinctus and Tamandua tetradactyla. In addition, the function assigned to each branch was the same regardless of the species with which it was compared

On the scattering amplitude in the Aharonov-Bohm gauge field

A general expression for the scattering amplitude of nonrelativistic spinless particles in the Aharonov-Bohm gauge potential is obtained within the time independent formalism. The result is valid also in the backward and forward directions as well as for any choice of the boundary conditions on the wave function at the flux tube position.Comment: 18 pages, plain TE

Análise e mineração de dados de sensores orbitais para acompanhamento de safras de cana-de-açúcar.

Resumo. O impacto causado por eventos climáticos extremos em todo o mundo tem motivado pesquisas para redução de gases de efeito estufa. No Brasil, a cana-de-açúcar é a principal fonte para produção de etanol, como alternativa a combustíveis fósseis. Nesse contexto, dados de sensoriamento remoto têm sido utilizados para monitorar safras de cana-de-açúcar e apoiar pesquisas científicas. Neste trabalho, é proposta uma metodologia baseada em agrupamento de dados para analisar séries temporais de NDVI obtidas de satélites AVHRR/NOAA. Os experimentos mostram que a abordagem proposta permite identificar áreas com padrões de desenvolvimento similares, considerando também os diferentes ciclos de vida da cultura.WCAMA 2011

Diet with detoxified castor meal increase unsaturated fatty acids in goat milk and cheese.

Abstract: By-products of industrial processes nutritionally rich as castor meal have been used as an energy source in feed for goats in order to increase the lipid characteristics of milk and dairy products. The present study was conducted to evaluate the physicochemical, microbiological and sensory properties of goat cheese "Coalho Type" made from milk of goats submitted to diets with increasing levels (33, 67 and 100%) of detoxified castor meal, replacing soybean meal. The cheeses produced showed no changes in sensory attributes (P>0.05). However, the diet with different levels of detoxified castor meal promoted an increase in the levels of unsaturated fatty acids in milk and cheese, especially the C6:0; C10:0; C14:0; C16:0; C18:1 and C18:3 profile, whereas reduced contents of saturated fatty acids were observed (P<0.05). The results suggest detoxified castor meal as a promising alternative for use in the diet of dairy goats in total replacement of soybean meal
