13. Visualización y Razonamiento Configural
Abstract This research analyses the relationships between the identification of prototypical figures and geometrical knowledge in solving proof problems as a evidence of configural reasoning. We analyze the answers of 182 preservice teachers on two geometrical proof problems, which include a geometrical configuration and a request for proving a geometrical f

14. Isolated plexiform neurofibroma mimicking a vascular lesion
Abstract Plexiform neurofibromas are benign tumors originating from peripheral nerve sheaths, generally associated with Neurofibromatosis Type 1 (NF1). They are diffuse, painful and sometimes locally invasive, generating cosmetic problems. This report discusses an adolescent patient who presented with an isolated, giant plexiform neurofibroma on her leg that

15. Assessment model of urban sustainability level: proposal to brazilian cities
AbstractSustainability indicators allow to capture urban environment features and reveal the urban (in)sustainability, generating information that support urban public policies and the development process. Based on this evidence, the paper aims to propose a model for urban sustainability analysis, built from matrices of Ascelrad (2009). This proposal is divi

16. A benchmark study on intelligent sampling techniques in Monte Carlo simulation
In recent years, new, intelligent and efficient sampling techniques for Monte Carlo simulation have been developed. However, when such new techniques are introduced, they are compared to one or two existing techniques, and their performance is evaluated over two or three problems. A literature survey shows that benchmark studies, comparing the performance of

17. Pathological, immunohistochemical, and molecular findings in commercial laying hens and in backyard chickens naturally infected with the infectious laryngotracheitis virus
Seventy-eight chickens from a very high poultry density (approximately eight million) region and twelve backyard chickens from neighboring areas were analyzed by histopathology and additional techniques for the presence of the infectious laryngotracheitis virus. The virus distribution was determined in different tissues using immunohistochemistry (IHC) and p

19. Determinación de indicadores de eutrofización en el embalse Río Tercero, Córdoba (Argentina)
Eutrophication is one of the most important environmental problems in lakes and reservoirs. Río Tercero reservoir (Argentina) is affected by various human activities that impact negatively on the system. When generating a monitoring program of aquatic systems, one of the most important considerations is to define the most significant variables. Multivariate

21. Classificação do café beneficiado: uma proposta para pagamento pela qualidade dos grãos
Brazil is the largest world coffee producer and exporter. The crop arrived in the country in the colonial period, in the mid-seventeenth century, and during much of the nineteenth and twentieth centuries was the Brazilian main export product. Brazil produces coffees of different qualities. In raw grain status, the product is traded after being benefited in t
