    The responses of Medicago sativa, Phaseolus atropurpureus and Stylosanthes gracilis to lime applications to four latosols and four red-yellow podzols of the State of São Paulo were measured in a greenhouse trial. Alfalfa responded to lime in the pH range of 4.5 to 6.0 with maximum yields at 6.4 or above in all soils. In only one soil, liming to pH values above the maximum caused a decreased yield of alfalfa. Applications of Mn to two soils decreased yield of alfalfa only at pH values of less than 5.5. The average maximum yield of Phaseolus for all soils was at a pH of 6.1, and for Stylosanthes the average maximum yield was at pH 6.4. The average responses to lime in the pH range from 4.5 to 6.0 were 93% and 146% for Phaseolus and Stylosanthes respectively. Both of these tropical legumes reduced yields as the pH increased above the region of 6.2 to 6.4. However, Phaseolus and Stylosanthes yields greatly increased in some soils and were unchanged or reduced in others. A significant interaction between soils, legumes and Mn treatments was found.Experimentos conduzidos em casa de vegetação mediram as respostas de Medicago activa, Phaseolus atropurpureus e Stylosanthes gracilis à aplicação de calcário em oito solos do Estado de São Paulo, sendo quatro latossolos e quatro podzólicos vermelho-amarelos. A alfafa respondeu ao calcário em toda a faixa de pH de 4,5 a 6,0, obtendo-se produções máximas ao nível de pH 6,4, ou mais, em todos os solos. Somente em um solo a aplicação de calcáro para valores de pH acima do máximo determinou decréscimo de produção de alfafa. Aplicação de Mn a dois solos resultou em decréscimos de produção, mas somente quando o pH do solo estava abaixo de 5,5. As maiores médias de produção de Phaseolus em todos os solos foram obtidas com pH 6,1 e as de Stylosanthes com pH 6,4. As respostas ao calcário medidas na faixa de pH de 4,5 a 6,0 foram, respectivamente, 93% para Phaseolus e 146% para Stylosanthes. Decréscimos de produção destas duas leguminosas tropicais foram verificados quando o pH ultrapassou a faixa de 6,2 a 6,4. No entanto, enquanto a produção de Phaseolus e Stylosanthes foi bastante aumentada em alguns solos, não chegou a ser afetada ou foi mesmo reduzida pela calagem aplicada em outros solos. Foi significativa a interação entre solos, leguminosas e tratamentos com Mn

    The granular layered magnetic system Co80Fe20(t)/Al2 O3 (3 nm), where the Co80Fe20 layers of nominal thickness t form separate, almost spherical magnetic granules of typical diameter 2-3 nm between the Al2O3 spacers, was studied. We discuss measurements of the dc and ac magnetic susceptibility χ for 1 n

    ABSTRACT The present study aimed to perform an epidemiological survey on the prevalence rate of oral lesions diagnosed in a referral center in Brazil and to establish association between the lesions and the age and gender of the affected patients. This analytical observational study analyzed 3521 medical records of anatomopathological exams of the Pathological Anatomy and Cytopathology Laboratory of the Cancer Hospital of the state of Mato Grosso (Brazil), from December 2011 to September 2015. A total of 1550 relevant medical records was detected. Patients aging between 41 and 60 consisted of 42.84% of the sample. Males were more affected than females (60.13%). Inflammatory processess consisted of the most prevalent diagnosis (43.29%), followed by squamous cell carcinoma (6.06%), and periapical granuloma (5.23%). Oral health public policies must give major attention to Brazilian males aged between the fourth and sixth decades of life in order to improve their quality of life

    Determining factors of functioning in hemodialysis patients using the international classification of functioning, disability and health

    Background: Hemodialysis (HD) treatment affects functioning, physical activity level, clinical biomarkers, and body composition. However, the association between these variables with functioning, considering International Classification of Functioning, Disability and Health (ICF) domains remains unclear. Thus, the aim of this study was to investigate the possible association between physical activity, biomarkers, and body composition with functioning in HD patients in reference to the ICF. Methods: Eighty HD patients performed different tests grouped according to ICF domain: Body structure and function – handgrip strength (HS), 5-repetition sit-to-stand test, and 60-s sit-to-stand test (5-STS, 60-STS, respectively); Activity – short physical performance battery (SPPB); and Participation – participation scale questionnaire. Physical activity [Human Activity Profile questionnaire (HAP)], body composition (Dual-energy X-ray absorptiometry), Parathormone (PTH), and alkaline phosphatase were analyzed as possible variables associated with ICF domains. Data analyses were performed using simple and multiple regression models adjusted for age, duration of HD, and diuresis volume. Results: In the body structure and function domain, appendicular lean mass, PTH level, and age were associated with HS ( R2 = 0.558); HAP and PTH were associated with 5-STS ( R2 = 0.263); and HAP, PTH, duration of HD, and age were associated with 60-STS ( R2 = 0.337). In the activity domain, HAP, PTH, alkaline phosphatase, duration of HD, age, and body fat were associated with SPPB ( R2 = 0.689). Finally, only HAP was associated with the participation scale ( R2 = 0.067). Conclusion: Physical activity and PTH levels are determinant protagonists of functioning in all ICF domains in hemodialysis patients

    CARACTERÍSTICAS FÍSICO-QUÍMICAS DA CASCA DO MARACUJÁ AMARELO (Passiflora edulis Flavicarpa Degener) OBTIDA POR SECAGEM

    O objetivo desse trabalho foi determinar a composição centesimal e o teor de fibras (solúvel, insolúvel e alimentar) da casca do maracujá amarelo (Passiflora edulis Flavicarpa Degener), obtida por secagem. Foram utilizadas amostras produzidas na região de Araquari, Santa Catarina (Brasil). Por meio dos resultados obtidos foi possível observar que a casca desse maracujá é rica em fibras solúveis e minerais. Assim, as indústrias de processamento de suco de maracujá podem utilizar o resíduo orgânico dessas cascas para desenvolver novos produtos a base de fibras
