Abstract: the south american tomato pinworm was first detected in brazil in 1980 and today it is among the major pests of tomato in brazil. the control of this pest has been done primarily with the use of insecticides, and three sprays per week may be necessary in extreme cases. wild tomato accessions such as s. pennellii la-716 possess high levels of insect resistance, mediated by high foliar contents of acylsugars. the objectives of this study were obtain improved tomato genotypes with high contents of leaf acylsugars, and to assess their levels of resistance to the south american tomato pinworm tuta absoluta. these genotypes were obtained from segregating (f2) populations from the cross between af-8665 (an elite low as tomato line) and lines bpx370e-30-275-11-7, bpx370e-30-275-11-8, bpx370e-30-380-68-6 and bpx370e-30-380-68-8 (pre-commercial high as inbreds derived from an original interspecific cross between s. lycopersicum x s. pennellii la-716). f2 plants selected for high as contents were cloned and subsequently tested for pinworm resistance. the high as genotypes showed smaller ovoposition counts and lower plant damage levels than low as genotypes (commercial or not). even though high as genotypes were generally more resistant to the south american tomato pinworm than low as genotypes, their actual levels of resistance may be background-dependent: high as clones with bpx-410h background had slightly higher levels of resistance than high as clones with bpx-370g background. clones bpx-410h-01pl#281, bpx-410h-04pl#348 and bpx-410h-04pl#481 had the highest levels of pinworm resistance, and were recommended for further use in breeding programs.
Moderniza??o, políticas públicas e sistema de gênero no Brasil: educa??o e profissionaliza??o feminina entre as décadas de 1920 e 1940
Azevedo, Nara;Ferreira, Luiz Otávio;
Cadernos Pagu , 2006, DOI: 10.1590/S0104-83332006000200009
Abstract: the social policies and, more specifically, the educational policies implemented in brazil as of the 1920's in an isolated base, and effectively institutionalized during the vargas era, encouraged a formal schooling process experimented by an important number of women, mostly by those from an urban middle class. these experiences were considerably responsible for relevant changes in the gender system, particularly in respect to women professional insertion in the academic and scientific world. this article aims to review a rather recognized interpretation in the specialized literature that tends to minimize the consequences produced by these reforms in the educational profile of the female population.
Os dilemas de uma tradi??o científica: ensino superior, ciência e saúde pública no Instituto Oswaldo Cruz, 1908-1953
Azevedo, Nara;Ferreira, Luiz Otávio;
História, Ciências, Saúde-Manguinhos , 2012, DOI: 10.1590/S0104-59702012000200013
Abstract: the article analyzes the tradition in medical and scientific teaching that was established at the instituto oswaldo cruz starting in 1908, introducing an innovative standard in training researchers and public health workers that combined teaching and research activities. forerunner of the university model, this tradition came up against the question of what social role the institute should play in the new institutional organization of public health and education implemented during the vargas era: should the institute serve public health or adopt a university-like format?
Hyperfunctioning thyroid cancer: a five-year follow-up
Azevedo, Monalisa Ferreira;Casulari, Luiz Augusto;
Arquivos Brasileiros de Endocrinologia & Metabologia , 2010, DOI: 10.1590/S0004-27302010000100013
Abstract: differentiated thyroid cancer rarely occurs in association with hyperfunctioning nodules. we describe a case of a 47-year-old woman who developed symptoms of hyperthyroidism associated with a palpable thyroid nodule. thyroid scintigraphy showed an autonomous nodule, and fine-needle aspiration biopsy was suggestive of papillary carcinoma. laboratorial findings were consistent with the diagnosis of hyperthyroidism. the patient underwent thyroidectomy and a papillary carcinoma of 3.0 x 3.0 x 2.0 cm, follicular variant, was described by histological examination. the surrounding thyroid tissue was normal. postoperatively, the patient received 100 mci of 131i, and whole body scans detected only residual uptake. no evidence of metastasis was detected during five years of follow-up. hot thyroid nodules rarely harbor malignancies, and this case illustrated that, when a carcinoma occurs the prognosis seems to be very good with no evidence of metastatic dissemination during a long-term follow-up.
Ecologia de comunidade de Bethylidae (Hymenoptera, Chrysidoidea) da Reserva Ecológica do Roncador, Brasília, Distrito Federal, Brasil
Azevedo, Celso Oliveira;Helmer, José Luiz;
Revista Brasileira de Zoologia , 1999, DOI: 10.1590/S0101-81751999000400021
Abstract: bethylidae specimens from the reserve were studied in its ecological and faunistic aspects. the material was collected by malaise and window traps simultaneously in ten different areas of the reserve during four years. the total number of genera and specimens were analyzed. indices of diversity and evenness were used for characterizing the community ecology. clustering analysis of localities and genera were provided. nine genera of bethylidae were found in the reserve, being pseudisobrachium kieffer, 1904 and apenesia westwood, 1874 the most common ones. window trap was more efficient than malaise trap in terms of genus diversity.
Igualdade e equidade: qual é a medida da justi a social? Equality and equity: what is the measure of social justice?

Avalia??o: Revista da Avalia??o da Educa??o Superior (Campinas) , 2013,
Abstract: O artigo procura analisar os conceitos de igualdade e de equidade em conex o com o ideal de justi a social que, em conjunto, s o caros valores humanos que balizam políticas (e lutas) sociais. A Igualdade e a equidade substantivas, com suas sutis diferen as de entendimento, s o princípios fundamentais para a formula o de políticas públicas voltadas para a promo o da justi a social e da solidariedade. The article analyzes the concepts of equality and equity (or fairness) and their connection to the ideal of social justice which, together, are fundamental human values that guide social policies (and social struggles). The substantive equality and equity (or fairness), with subtle differences in their understanding, are essential principles for the formulation of public policies for the promotion of social justice and solidarity.

Abstract: Este trabalho trata a respeito do processo de integra o dos sistemas de educa o superior na Europa, regi o que, desde o fim da segunda guerra mundial, está procurando eliminar as fronteiras em todos os ambitos. O Processo de Bolonha, homenagem à universidade mais antiga da Europa, é o nome do conjunto dos eventos (reuni es, resolu es e normas) relativos às medidas de implementa o dos princípios da reuni o de ministros da educa o europeus que ocorreu em Bolonha, em 1999, com a finalidade de construir um espa o europeu de educa o superior até o ano 2010, cujos objetivos fundamentais encetam, principalmente, para a competitividade do Sistema Europeu de Ensino Superior frente a outras regi es e para a mobilidade e o emprego no Espa o Europeu. Dessa maneira, analisa-se também o papel dos atores sociais nesse processo e a discuss o a respeito da natureza da educa o superior: um bem público catalisador da solidariedade internacional ou uma mercadoria a ser explorada na constru o de um mercado educativo transnacional. This paper analysis the integration process of higher education system in Europe, region that, since the end of Second World War is trying to eliminate the borders in all scopes. The Process has been named as Bologna's Process, to homage the older Europe's university. It is a set of resolutions, events and rules, related to the implementation measures of the principles resulted of the European ministers meeting, occurred in Bologna in 1999, with the purpose of building an European space of higher education until 2010. The fundamental goals are competitiveness of the front Higher education European system to others regions, mobility and the job in the European Space. It analysis also the social actor’s roll in this process and the discussion concerning about of nature of higher education: one very public aspect of the international solidarity or a exploratory merchandise to being explored in the construction of a transnational educational market.

An assessment of unstructured grid finite volume schemes for cold gas hypersonic flow calculations
Jo?o Luiz F. Azevedo,Heidi Korzenowski
Journal of Aerospace Technology and Management , 2009,
Abstract: A comparison of five different spatial discretization schemes is performed considering a typical high speed flow application. Flowfields are simulated using the 2-D Euler equations, discretized in a cell-centered finite volume procedure on unstructured triangular meshes. The algorithms studied include a central difference-type scheme, and 1st- and 2nd-order van Leer and Liou flux-vector splitting schemes. These methods are implemented in an efficient, edge-based, unstructured grid procedure which allows for adaptive mesh refinement based on flow property gradients. Details of the unstructured grid implementation of the methods are presented together with a discussion of the data structure and of the adaptive refinement strategy. The application of interest is the cold gas flow through a typical hypersonic inlet. Results for different entrance Mach numbers and mesh topologies are discussed in order to assess the comparative performance of the various spatial discretization schemes.

Abstract: The beet (Beta vulgaris L.) vegetable is of great importance in the Brazilian market, mainly by having high nutritional values in consumer diet. Thus, the objective of this work was to evaluate the effects of organic and mineral fertilization on the production and post-harvest quality of beet. The experiment was conducted in the field, in the municipality of Urutaí-GO. The experimental design was a randomized block (DCB), where treatments were applied to two types of fertilizer: organic (chicken manure) and conventional (mineral fertilizer) with six replicates (using six tubers per plot). The following evaluations were made: horizontal and vertical diameters of the tubers (cm) weight (kg) Protein (g) Lipid (%) Ash humidity (%), electrical conductivity (μS·cm-1), pH, Titratable Acidity and Brix. The organic surpassed conventional treatment for all variables, except for the ash content, wherein the organic treating poultry litter base, showed 1.40% of ash and pH (6.48).
