13. Modelos lineares mistos em dados longitudionais com o uso do pacote ASReml-R / Linear Mixed Models with longitudinal data using ASReml-R package
Currently, most part of the experiments installed is designed to be carried out observations over time or at different depths. These experiments usually have a longitudinal factor. One way of analyzing this data set is by using mixed models through means of inclusion of random effect factors, and it is possible to estimate the variance components associated

14. Secretory structures of Ipomoea asarifolia: anatomy and histochemistry
Ipomoea asarifolia (Desr.) Roem. & Schult., Convolvulaceae, is a weed that infests agricultural areas and is toxic to cattle. In spite of its toxicity, the leaves of this plant are used in traditional remedies in the state of Bahia, Brazil. The present work describes the leaf anatomy of I. asarifolia and characterizes the exudates of its secretory structures

16. Radarsat backscattering from an agricultural scene.
Orbital remote sensing in the microwave electromagnetic region has been presented as an important tool for agriculture monitoring. The satellite systems in operation have almost all-weather capability and high spatial resolution, which are features appropriated for agriculture. However, for full exploration of these data, an understanding of the relationship

17. Sistemas agroflorestais : um caminho para agricultura sustentável à luz da cultura camponesa / Agroforestry systems : a path for sustainable agriculture under the light of peasant culture
The central issue approached in our work is the constitution of agroforestry systems (AFSs) under the farmers point of view within their family practices. Our objective is to analyze to what extent the peasant culture structures the practices and principles of agroforestry systems. The methodological path built here unveils the path traced by research agents

18. Modelos não-lineares para dados longitudinais provenientes de experimentos em blocos casualizados abordagem bayesiana / Nonlinear models for longitudinal data from experiments in randomized block design a bayesian framework
Data consisting of repeated measurements taken on each of a number of individual arise commonly in agricultural and biological applications. Modeling data of this kind usually involves the characterization of the relationship between the measured response and covariate. In many application,the proposed systematic relationship between the measured response is

19. Molecular characterization of beta-tubulin from Phakopsora pachyrhizi, the causal agent of Asian soybean rust
β-tubulins are structural components of microtubules and the targets of benzimidazole fungicides used to control many diseases of agricultural importance. Intron polymorphisms in the intron-rich genes of these proteins have been used in phylogeographic investigations of phytopathogenic fungi. In this work, we sequenced 2764 nucleotides of the β-tubulin gen

20. CERRITOS AS CULTURAL PATRIMONY: THE RESCUE OF THE ARCHAEOLOGICAL SITE CORREDOR DO BOLSO / CERRITOS COMO PATRIMÔNIO ARQUEOLÓGICO: O RESGATE DO SÍTIO ARQUEOLÓGICO CORREDOR DO BOLSO
This paper presents the current research in the Archaeological Site Corredor do Bolso, located at Santa Margarida do Sul munipality, Rio Grande do Sul state, Brasil. The site, excavated in 1998, was impacted by agricultural activities, but still preserved two partially intact mound structures, known in the literature as Cerritos. The studied collection is co

21. Organic matter in Albaqualf as affected by managements irrigated rice cropping systems the South from Brazil / Matéria orgânica em Planossolo Háplico sob sistemas de manejo no cultivo do arroz irrigado no Sul do Brasil
In the south region from Rio Grande do Sul State, in,Brazil, 950 thousand hectares of soils are cultivated with rice, an important agricultural activity in that region, under an irrigation (flooded) system, using different soil management techniques. Studies regarding the organic matter (OM) dynamic in these soils are incipient, so this work aimed to evaluat

23. Sales managers' performance and social capital: the impact of an advice network
The aim of this study is to research a sales manager's social network and demonstrate that sales managers who are central in closure structures of an advice network achieve high sales performance. Considering the results obtained and the discussion provided in the hypotheses presentation, we argue that sales managers must have accurate perceptions of their n

24. Desenvolvimento econômico e biossegurança: uma análise crítica ética, jurídica, econômica e social da utilização dos organismos geneticamente modificados
One frequently resorts to science to legitimize the primacy attributed to Biotechnology and to the privileged protection granted to the rights of intellectual property that are conferred on it. Therewith, there is a tendency to accept, as a presupposition, that the future must and will be shaped by the biotechnological advances. Therefore, any criticism to t
