1. SPECIES-SPECIFIC EQUATIONS: GREATER PRECISION IN COMMERCIAL VOLUME ESTIMATION IN MANAGED FORESTS IN THE AMAZON
ABSTRACT The objective of this study was to analyze the performance of species-specific equations (SSEs) concerning generic ones in Annual Production Units (GEAPUs) and in a Forest Management Area (GEFMA) in the Brazilian Amazon. A total of 29,119 trees from 43 species were inventoried, harvested, and volumetric measurements were taken in ten APUs, with 10%

2. Machine learning para análises preditivas em saúde: exemplo de aplicação para predizer óbito em idosos de São Paulo, Brasil
Este estudo objetiva apresentar as etapas relacionadas à utilização de algoritmos de machine learning para análises preditivas em saúde. Para isso, foi realizada uma aplicação com base em dados de idosos residentes no Município de São Paulo, Brasil, participantes do estudo Saúde Bem-estar e Envelhecimento (SABE) (n = 2.808). A variável resposta fo

3. Prediction of Topsoil Texture Through Regression Trees and Multiple Linear Regressions
ABSTRACT: Users of soil survey products are mostly interested in understanding how soil properties vary in space and time. The aim of digital soil mapping (DSM) is to represent the spatial variability of soil properties quantitatively to support decision-making. The goal of this study is to evaluate DSM techniques (Regression Trees - RT and Multiple Linear R

4. INCLUDING RISK IN ECONOMIC FEASIBILITY ANALYSIS:A STOCHASTIC SIMULATION MODEL FOR BLUEBERRY INVESTMENT DECISIONS IN CHILE
ABSTRACT The traditional method of net present value (NPV) to analyze the economic profitability of an investment (based on a deterministic approach) does not adequately represent the implicit risk associated with different but correlated input variables. Using a stochastic simulation approach for evaluating the profitability of blueberry (Vaccinium corymbo

5. Decision trees for the inference of ineffective airway clearance and ineffective breathing pattern of children with acute respiratory infection. / Ãrvores de decisÃo para inferÃncia de desobstruÃÃo ineficaz de vias aÃreas e padrÃo respiratÃrio ineficaz de crianÃas com infecÃÃo respiratÃria aguda.
Muitas dificuldades sÃo encontradas na implementaÃÃo de classificaÃÃes de enfermagem na prÃtica clÃnica. Destaca-se a falta de familiaridade dos enfermeiros com os sistemas de classificaÃÃo e as dificuldades na tomada de decisÃo diagnÃstica associadas Ãs deficiÃncias no processo de raciocÃnio diagnÃstico. Assim, estudos que desenvolvam ferrame

6. Genomic selection in Eucalyptus: marker assisted selection coming to reality in forest trees.
Genomic selection (GS) involves selection decisions based on genomic breeding values estimated as the sum of the effects of genome-wide markers capturing most QTLs for the target trait(s). GS is revolutionizing breeding practice for complex trait in domestic animals. The same approach and concepts can be readily applied to forest tree breeding. Trees also ha

7. Características de árvores emergentes utilizadas por Gavião-real (Harpia harpyja) para nidificação no centro e leste da Amazônia Brasileira
The Harpy eagle (Harpia harpyja) the American powerful raptor lives thought the New Worlds forests, from the south of Mexico to the northeast of Argentina. Between 1984 and 2000, that species was listed in a threatened of extinction Brazilian species list. At the Atlantic Forest the population declined drastically, by the way of the deforestation - the watch

8. Discordant Phylogenies within the rrn Loci of Rhizobia†
It is evident from complete genome sequencing results that lateral gene transfer and recombination are essential components in the evolutionary process of bacterial genomes. Since this has important implications for bacterial systematics, the primary objective of this study was to compare estimated evolutionary relationships among a representative set of α-

9. The role of oak pollen in hay fever consultations in general practice and the factors influencing patients' decisions to consult.
BACKGROUND: Patients often consult for hay fever before significant counts of grass pollen are recorded, and this has prompted the question, 'Are symptoms already present or are patients consulting to obtain medication in anticipation?' AIM: The study is concerned with the relationship between hay fever symptoms and pollens, and also with the impact of the m
