1. IDENTIFICATION OF MAIZE LODGING: A CASE STUDY USING A REMOTELY PILOTED AIRCRAFT SYSTEM
ABSTRACT A common agricultural problem in many regions of Brazil is maize lodging, as a consequence of strong winds and rain which impacts on crop growth and yield. However, collecting data using ground-based, manual field measurement methods is inefficient. An emerging tool is the Remotely Piloted Aircraft System (RPAS), capable of delivering spatial data w

2. Annual tree rings in Piptadenia gonoacantha (Mart.) J.F.Macbr. in a restoration experiment in the Atlantic Forest: potential for dendroecological research
ABSTRACT The tree Piptadenia gonoachantha is widely used in forestry and in forest restoration projects, which require methods for evaluating tree growth. Long-term studies are necessary to determine patterns and detect changes in species growth rhythms. Tree ring analysis provides a precise method for determining age and documenting long-term growth trends

3. Age and growth of Cetengraulis edentulus (Clupeiformes: Engraulidae) in a subtropical bight of Southern Coast Brazil
Age and growth of Cetengraulis edentulus (Cuvier, 1828) in the Saco dos Limões bight (Southern Brazil) were studied. Sampling was carried out from August 2001 to July 2003. The study of age and growth was based on the interpretation of the periodicity of ring formation in the otoliths sagittae of 491 individuals, temporal variation of otolith edge, relative

5. Dinâmica de crescimento de Cedrela odorata L. (Meliaceae) na Floresta Atlântica do Estado do Rio de Janeiro: fenologia, atividade cambial e dendrocronologia / Growth dynamics of Cedrela Odorata L. (Meliaceae) on the Atlantic Rain Forest of the State of Rio de Janeiro: phenology, cambial activity and dendrochronology
Along the 20th century, a few dendrochronological studies were developed with tropical species, according to the belief that variations of the climatic conditions on those regions werent regular and strong enough to induce an annual rate of radial growth. The researches on this topic in the last decades showed that the formation of annual growth rings in the

6. Accounting earnings properties and determinants of earnings response coefficient in Brazil / Propriedades do lucro contábil e determinantes do coeficiente de resposta ao lucro no Brasil
A fundamental issue at the interface of economics, finance, and accounting involves the relation between a firms reported earnings and its stock returns. The lack of research in this field using Brazilian data and the limitations of previous research in terms of time-series data (small length available) motivates the present research. In addition, the practi

7. Orchidaceae nativas da região central de São Paulo, Brasil : florística, interação com forófitos, proposta de novas espécies e propagação in vitro de uma espécie ameaçada de extinção / Native Orchidaceae of the central region of São Paulo, Brazil: floristic, interaction nested with host tree, new species proposed and in vitro propagation of threatened of extinction species
Aiming to know the sorts of Orchidaceae of the central region of the State of São Paulo, from 1996 and more intensively from 2005, visits were carried out in 125 forest fragments of 23 local municípios, with weekly periodicity and also, fortnightly. The collect were assistematics, being each fragment visited in the biggest number of points. The species not

8. Anéis de crescimento de Araucaria angustifolia (Bertol.) O. Kuntze : bases de dendroecologia em ecossistemas subtropicais montanos no Brasil / Growth rings of Araucaria angustifolia (Bertol.) O. Kuntze : fundamentals of dendroecology in subtropical moutain ecosystems in Brazil
Determinadas espécies arbóreas apresentam ciclos anuais de crescimento e dormência, registrados no lenho por conspícuas estruturas anatômicas – os anéis de crescimento. Nessas árvores pode-se determinar a idade e taxas de crescimento, com resolução calendária anual, através da análise temporal dos anéis de crescimento (dendrocronologia), bem c

9. Vegetative growth periodicity of Coffee (Coffea arabica L.) tree at different trigger irrigation tensions and two planting densities. / Periodicidade de crescimento do cafeeiro (Coffea arabica l.) em diferentes tensÃes de irrigaÃÃo em duas densidades de plantio
Os cafeicultores brasileiros vÃm necessitando a cada dia aumentar suas produtividades para sobreviver a um mercado cada vez mais competitivo. A periodicidade do crescimento vegetativo do cafeeiro està associada a diversos fatores como temperatura, fotoperÃodo e irradiÃncia, suprimento de Ãgua e nutrientes, mas, desde que a temperatura seja favorÃvel o

10. UMA INVESTIGAÇÃO ECONOMÉTRICA DO MODELO LOG-PERIÓDICO PARA PREVISÃO DE CRASHES FINANCEIROS / THE LOG PERIODIC MODEL FOR FINANCIAL CRASHES FORECASTING: AN ECONOMETRICINVESTIGATION
In this work we employ a model based on the critical phenomena theory to explain the asset price formation associated to the pre- crash period. The evolution of the price is given by an over-all power law acceleration decorated by oscillations called log-periodic model. This growth is likely to be interrupted by a crash of prices that happen in a short and c

12. Relationship between seasonality, hedging and carbohydrates on growth of eucalypts in the vegetative propagation by minicuttings. / Relação entre sazonalidade, desrama e carboidratos no crescimento do eucalipto na propagação vegetativa por miniestaquia.
The importance of the Eucalyptus in the current conjuncture of Brazilian forestry has stirred up significant investments in research, which has leaded to the development of the improved methods of vegetative propagation. The clonal propagation of Eucalyptus spp. allows the fast multiplication of selected genotypes, allowing high gains even with characteristi
