Altura da enxertia de copa da seringueira. Efeitos sobre o crescimento e o custo da enxertia.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: MORAES, V. H. de F.
O principal argumento para a recomendacao de aumento da altura da enxertia de copa com clones resistentes ao mal-das-folhas da seringueira e' a manutencao de painel disponivel para sangria alta, caso haja perda antecipada da capacidade de producao do painel baixo original.

Double Root Anatomical Variations in a Single Patient: Endodontic Treatment and Rehabilitation of a Three-rooted First Premolar. Case Report
Provedor de dados: International Journal of Morphology
Autores: Oporto V,Gonzalo H; Saavedra,Rubén; Soto P,Camila C; Fuentes,Ramón.
Abnormal interaction between oral epithelium and underlying mesenchematic tissue during odontogenesis could result in teeth with an anatomical variation. First maxilar premolar has such variable root canal morphology. However, (0.2-6% of cases) a three-rooted premolar is particularly uncommon. First mandibular premolar frequently has one root and one single canal (75% of cases), however, a tooth with two canals and two separate roots could be found (19.5-22.5%). Execution of an accurate diagnosis of root canal system is essential to perform a successful endodontic treatment and tooth rehabilitation. This article describes diagnosis, endodontic treatment and rehabilitation (means single crown) of a maxillary three-rooted and three-canal first premolar, and...

Modeling natural regeneration biomass of Pinus stand
Provedor de dados: PFB - Pesquisa Florestal Brasileira
Autores: Cubas, Rafael; Costa, Emanuel Arnoni; Guimarães Finger, César Augusto; Maydanchen, Viviane Zaniz.
Reliable biomass data are very important in the evaluation of ecosystems, and help in understanding the contribution of forests in climate change. Variables that describe the size of the tree, like diameter and height are directly associated with biomass, which allows the use of regression models to estimate this element. Therefore, this study aimed to estimate by regression models, the biomass of different compartments of natural regeneration of trees of a Pinus taeda L. stand. The data were obtained through direct destructive method, using 100 randomly selected trees in the understory of a stand of Pinus taeda. We analyzed three arithmetical models, three logarithmic and two models developed by Stepwise process. Logarithmic equations developed by...
