The role of teaching decision analysis for sustainability in engeneering schools

This paper addresses the role that decision analysis plays in helping engineers to gain a greater understanding of the problems they face. The need of structured decision analysis is highlighted as well as the use of multiple criteria decision analysis to tackle sustainability issues with emphasis in the use of MACBETH approach. Some insights from a Portuguese Summer Course on engineering for sustainable development are presented namely the students 'and teacher perceptions about the module of decision analysis for sustainability.

Ethnoveterinary knowledge of the inhabitants of Marajó Island, Eastern Amazonia, Brazil

There have been ethnoveterinary reports from around the world investigating plant usage in therapeutic protocols; however, there is no information regarding the ethnoveterinary practices in Brazilian Amazonia. The objective of this work was to register and document the ethnoveterinary knowledge of the inhabitants of the Island of Marajó, eastern Amazonia, Brazil. In the study, interviews were conducted with 50 individuals, with the application of semi-structured questionnaires that were quantitatively analyzed using descriptive statistic methods of frequency distribution. Use-value was calculated to determine the most important species. Samples of plants that were reported to have medicinal value were collected and identified by botanical classification. Fifty plants, distributed among 48 genera and 34 families, were indicated for 21 different medicinal uses. The family Asteraceae had the largest number of reported species; Carapa guianensis Aubl., Copaifera martii Hayne, Crescentia cujete L., Caesalpinia ferrea Mart., Chenopodium ambrosioides L., Jatropha curcas L. and Momordica charantia L. were species with highest use- value. The plant parts that were more commonly utilized for the preparation of ethnoveterinary medicines were the leaves (56%), bark (18%), roots (14%), seeds (14%) and fruit (8%). With regard to usage, tea was reported as a usage method by 56% of the informants; most preparations (90.9%) utilized only a single plant. In addition to medicinal plants, informants reported using products of animal and mineral origin. The present study contributed to the construction of an inventory of Marajó Island's ethnoveterinary plants, which might be the basis for future scientific validation studies.

A contribution to the knowledge of the Brazilian Strepsiptera: (Insecta)

Neste trabalho procuramos atualizar e acrescentar observações novas ao conhecimento dos Strepsiptera do Brasil. Descrevemos 4 espécies novas da família Myrmecolacidae, representados apenas por machos e uma espécie nova da família Halictophagidae, representada por macho, fêmea e hospedador. Registramos a ocorrência, no Brasil, de uma espécie da família Stylopidae, conhecida anteriormente da Argentina e fornecemos dados adicionais sôbre uma espécie da família Mengeidae, Triozocera paulistana Kogan, 1958. Baseados em HOFENEDER & FULMEK (1942-43) damos a lista dos hospedadores encontrados estilopizados no Brasil.

Fifth contribution to the knowledge of the genus Archytas Jaennicke, 1867 (Diptera, Tachinidae)

No presente trabalho são redescritas as seguintes espécies do gênero Archytas Jaennicke, 1867: Archytas lateralis Macquart, 1842, Archytas metallicus Desvoidy, 1830; Archytas aterrimus Desvoidy, 1830 e Archytas willistoni Curran, 1925. São ainda descritas duas espécies novas, provenientes do Estado do Pará, Brasil: Archytas pearsoni e A. araujoi. O material estudado pertence à coleção do Instituto Oswaldo Cruz, Rio de Janeiro.

Contribution to the knowledge of Philometra lateolabracis Yamaguti, 1935 (Nematoda, Filarioidea)

In this paper the authors refere Philometra lateolabracis Yamaguti, 1935 for the first time from the Atlantic Ocean also as a new host record. They report the rpesence of one male of diminished dimensions, found in close relationship with the females of Ph. lateolabracis; as the male of this species is unknown, they admit the possibility of this small nematode be the male of this species.
