Abstract: Forestry plantations should be regarded as an alternative sustainable land-use system in degraded savannah areas. They contribute to the maintenance of productive processes in degraded soils that are of economic importance for local inhabitants; in addition, in the ecological sense, timber and non-timber products from planted forests reduce the exploitation pressure on native forests. Eucalyptus plantations on degraded savannahs in the northern Brazilian Amazon may help to reduce exploitation pressure on native forests. However, there is no information regarding the nutrients rates that would allow faster eucalyptus growth in that region. A trial was installed in an Yellow Latosol (Oxisol) soil type adopting a one-half-type fractionalfactorial design with four rates of N, P, and K. Functions were adjusted for the dependent variables height, diameter at breastheight (DBH), leaf tissue nutrient content, and soil-chemical attributes. Interaction N versus K was observed on tree heightwith a maximum of 7.8 m recorded at 200 kg ha-1 of N and 50 kg ha-1 of K. Phosphorus fertilization promoted greater DBH growth with maximum value at 120 kg ha-1 of P; however, the highest gain was obtained at 30 kg ha-1 of P. The NPK rates that maximized Eucalyptus camaldulensis growth were 200, 30, and 50 kg ha-1, respectively. Planta es de eucalipto, em áreas de lavrado degradadas na Amaz nia Setentrional brasileira, devem contribuir para diminuir a press o de explora o em florestas nativas. Porém, n o há informa es sobre as doses de nutrientes que permitem o rápido crescimento do eucalipto nesta regi o. Um experimento para avaliar a resposta à aduba o do Eucalyptus camaldulensis foi instalado em Latossolo Amarelo, adotando o delineamento fatorial fracionário com quatro doses de nitrogênio (N), fósforo (P) e potássio (K). Fun es foram ajustadas para as seguintes variáveis dependentes: altura, diametro à altura do peito (DAP), conteúdo de nutrientes nas folhas e atributos químicos do solo. Foi observada intera o NxK para a altura, com um máximo de 7,8 metros registrados com a dose de 200 kg ha-1 de N e 50 kg ha-1 de K. A aduba o fosfatada promoveu o maior crescimento do DAP com o valor máximo obtido com a dose de 120 kg ha-1 de P; O maior ganho, entretanto, foi obtido com a dose de 30 kg ha-1 de P. As doses de NPK que maximizaram o crescimento do Eucalyptus camaldulensis foram 200, 30 e 50 kg ha-1, respectivamente.

Revista CEFAC , 2013,
Abstract: O tema deste estudo é a avalia o padronizada da linguagem em pacientes com les o cerebrovascular esquerda (LHE) que pode ser muito útil no estabelecimento do diagnóstico, prognóstico e plano terapêutico, complementando observa o, entrevistas e tarefas clínicas. Este estudo teve como objetivo identificar quais instrumentos de investiga o de linguagem têm sido utilizados para avalia o de quadros neurológicos súbitos envolvendo o hemisfério esquerdo (HE) e analisar quais componentes linguísticos s o os mais avaliados. Foi possível identificar nove instrumentos utilizados internacionalmente que avaliam diferentes componentes linguísticos em pacientes com LHE; no contexto nacional, porém, foram encontradas apenas duas baterias para avalia o dessa popula o, ficando evidente a necessidade da constru o e/ou de adapta o de instrumentos para a popula o brasileira. Os componentes linguísticos mais investigados foram nomea o e compreens o oral, respectivamente. A avalia o da linguagem torna-se essencial nos quadros envolvendo o HE, pois déficits linguísticos podem acarretar prejuízos sociais, ocupacionais e familiares. The theme of this study is the language assessment in patients with left brain damage (LBD). It is necessary as it helps to establish the diagnosis, prognosis and rehabilitation planning, adding findings to clinical observation, interview and tasks. The purpose is to identify which language instruments have been used to assess non-progressive neurological disorders involving the left hemisphere (LH) and to analyze which language components are the most assessed ones. It was possible to identify nine international instruments that assess different components of language in LBD patients. In the national context, however, only two batteries to assess this population were found, highlighting the need for construction and/or adaptation of language assessment tools for the Brazilian population. Naming and oral comprehension were the most examined linguistic components, respectively. The evaluation of language is essential in the neurological disorders that affect the LH, because language deficits can lead to an impaired social, occupational and family life.
Applying design of experiments (DOE) to flavonoid extraction from Passiflora alata and P. edulis

Revista Brasileira de Farmacognosia , 2012,
Abstract: The Passifloraceae family is extensively used in native Brazilian folk medicine to treat a wide variety of diseases. The problem of flavonoid extraction from Passiflora was treated by application of design of experiments (DOE), as an experiment with mixture including one categorical process variable. The components of the binary mixture were: ethanol (component A) and water (component B); the categorical process variable: extraction method (factor C) was varied at two levels: (+1) maceration and (-1) percolation. ANOVA suggested a cubic model for P. edulis extraction and a quadratic model for P. alata.These results indicate that the proportion of components A and B in the mixture is the main factor involved in significantly increasing flavonoid extraction. In regard to the extraction methods, no important differences were observed, which indicates that these two traditional extraction methods could be effectively used to extract flavonoids from both medicinal plants. The evaluation of antioxidant activity of the extract by ORAC method showed that P. edulis displays twice as much antioxidant activity as P. alata. Considering that maceration is a simple, rapid and environmentally friendly extraction method, in this study, the optimized conditions for flavonoid extraction from these Passiflora species is maceration with 75% ethanol for P. edulis and 50% ethanol for P. alata.
