13. Anomalías en los comienzos de la transgénesis vegetal: intereses e interpretaciones en torno a las primeras plantas transgénicas
The origins of plant transgenesis are discussed and the experiments that led to the first transgenic plants are analyzed. This process involved a series of actors, practices and interests specific to biotechnology. Consensus about the meaning of fundamental experiments was also at issue here. These events illustrate some of the conflicts related to genetical

14. Phlebotonics for haemorrhoids
BACKGROUND Haemorrhoids are variceal dilatations of the anal and perianal venous plexus and often develop secondary to the persistently elevated venous pressure within the haemorrhoidal plexus. Phlebotonics are a heterogenous class of drugs consisting of plant extracts (i.e. flavonoids) and synthetic compounds (i.e. calcium dobesilate). Although their preci

15. Resposta de genótipos de citros à leprose e variabilidade genética da ORF p29 do vírus da leprose dos citros C (CiLV-C) / Response of citrus genotypes to leprosis and genetic variability of ORF p29 from Citrus leprosis virus C (CiLV-C)
Viruses have, potentially, broad genetic variability because of their need to adapt to several changes that they are exposed to. Therefore, genetic variability is essential for their survival; it is the first step to adapt to a new host, to break resistance down, to change symptoms and virulence, which justifies the interest in studies in this area. These st

16. Métodos de quantificação de espécies metálicas por espectrometria atômica e avaliação nutricional em tecidos de jambú (Acmella oleracea)
O jambú (Acmella oleracea), hortaliça empregada na culinária e na medicina popular no Norte do Brasil, tem sido objeto de pesquisas em diversas áreas revelando aplicações promissoras. Entretanto, são encontrados poucos registros relacionados à sua composição e valor nutricional inorgânico. Neste estudo, foram desenvolvidos dois métodos de tratame

17. O argumento no trabalho de campo: abordando a sucessão ecológica na floresta da USP, campus de Ribeirão Preto / The argument in the fieldwork: approaching the ecological succession in the Forest of USP, Ribeirão Preto campus
In this research we investigate the discursive interactions that may lead to the promotion of scientific literacy during a field work activity related to Ecology in a reforested area. Many perspectives in the field of language and science teaching guided this study, among them the researches that consider that the practice of argumentation in the classroom a

19. Aspectos contábeis do Tratado de Itaipu : análise das práticas de avaliação dos ativos imobilizados da empresa Itaipu Binacional
In the seventies of the twentieth century, there was an expansion in the production of electricity in Brazil. On April 26, 1973 the Itaipu Treaty was concluded between Brazil and Paraguay which enabled the construction of a hydroelectric plant in the border between the two countries: the Itaipu Binacional, which is governed by the Itaipu Treaty and its Annex

20. Interação P×Zn avaliada pelos teores de Zn total e solúvel e pela atividade da enzima superóxido dismutase em mudas de cafeeiro / Interação P×Zn avaliada pelos teores de Zn total e solúvel e pela atividade da enzima superóxido dismutase em mudas de cafeeiro / Interaction P x Zn evaluated by the levels of total and soluble Zn and by the activity of dismutase superoxide enzyme in coffee seedlings / Interaction P x Zn evaluated by the levels of total and soluble Zn and by the activity of dismutase superoxide enzyme in coffee seedlings
The coffee tree is a demanding plant in micronutrients, especially Zn, and the P x Zn interaction is an important issue for the management of tropical soils, due to the use of high doses of P in soils with low availability of this nutrient. In this work was studied the seedlings response of Coffea arabica L. cv. Catuaí to doses of Zn and P, including the su

21. THE USE OF BIO-DIGESTERS IN SMALL AND MEDIUM RURAL PROPERTIES WITH EMPHASIS ON VALUE ADDING: A CASE STUDY FROM NORTHWESTERN REGION OF RIO GRANDE DO SUL STATE / O USO DE BIODIGESTORES EM PEQUENAS E MÉDIAS PROPRIEDADES RURAIS COM ÊNFASE NA AGREGAÇÃO DE VALOR: UM ESTUDO DE CASO DA REGIÃO NOROESTE DO RIO GRANDE DO SUL
From the duration of the Kyoto Protocol, there has been a renewed interest in technology of bio-digesters. As they allow a reduction in the emission of greenhouse gases compared to other waste treatment methods, their deployment can permit the marketing of carbon credits, resulting in money. The present study aims to analyze the process of dissemination of t

22. Avaliação in silico do transcriptoma do café : identificação de SNPs e inferência de mecanismos de regulação da expressão gênica / In silico analysis of the coffee transcriptome : identification of SNPs and inference of mechanisms of gene expression regulation
Coffee is one of the most important crops in the world, being worldwide consumed and having significant participation in under development economies. Coffea arabica and Coffea canephora are responsible for 70% and 30% of commercial production, respectively. Cytogenetic analysis established that C. arabica is an autogamous alotetraploid formed by a recent (1

23. Simulação da geometria e do desempenho do detector de antineutrinos do Projeto Angra / Simulation of the design and performance of the detector antineutrinos Angra Project
In this work is presented a comparative study between some geometries for the Neutrinos Angra Project detector. This Project was born from a colaboration that is dedicated to the construction of a compact antineutrinos detector for monitoring, in real time, the thermal power of Angra II nuclear reactor. Through the antineutrinos ux is possible to get informa

The situation of solid waste in Brazil is worrying, especially with regard to final disposal, as the increase in the wasteâs generation was not followed by a growth of infrastructure. The environmental issue, with the onset and worsening of environmental problems become more important to humans. Most of these problems is due to industrial waste origin, as m
