O artigo analisa a convergência municipal da produtividade vegetal (extração vegetal e silvicultura) na região da Amazônia Legal entre os anos de 1996 e 2006. Para analisar a convergência, optou-se pela metodologia da matriz de transição de Markov (Processo Estacionário de Primeira Ordem de Markov). Os resultados mostram a existência de 13 classes de convergência da produtividade vegetal. No longo prazo, a hipótese de convergência absoluta não se mantém, visto que 68,23% dos municípios encontram-se numa classe inferior à média municipal, 33,54% em uma classe intermediária acima da média e 13,41% em uma classe superior acima da média.

Compreendido por um bloco (A) constituído de material metálico, possuindo quatro parafusos para fixar o sensor à estrutura, bem como possui grande resistência mecânica a deformação quando ocorre a inclinação da estrutura, de maneira que o bloco (A) está ligado ao bloco (B) por meio de parafusos internos, sendo o bloco (B) desenvolvido em duralumínio, o qual sofre a ação de grandes tensões provocadas pela sensibilização decorrente da existência de dois orifícios retangulares (E) passantes que criaram as regiões sensoras (rs1) e (rs2), sendo que em cada região sensora existem duas membranas laterais ao orifício, de forma que, devido a sensibilização das regiões (rs1) e (rs2)

PURPOSE: Describe hearing aid use by the elderly population in the city of São Paulo and identify associated factors. METHODS: A cross-sectional, descriptive, quantitative study integrated with the SABE (health, well-being and aging) project developed in 2006. A total of 1.115 individuals aged 65 or over were interviewed. Sample selection occurred in two stages, with replacement and probabilities proportional to the population to complement those aged 75 or over. Structured questionnaires and validated instruments were used. The data were weighted, the Rao-Scott test was used for univariate analysis and backward stepwise logistic regression was used for multivariate analysis, performed on Stata 10® software. RESULTS: Three hundred and seventy-seven subjects (30.4%) were classified as hearing impaired and 10.1% of these reported using hearing aids. To acquire the devices, 78.8% used their own resources and 16.9% acquired them through the Brazilian public health system (SUS). Among non-users of hearing aids, 16.6% reported prior indication; however, 8.6% were unable to adapt to the device and 8.0% could not afford to acquire one. Hearing aid use was associated with lower prevalence of probable dementia. CONCLUSION: The low number of hearing aid users indicates the difficulties elderly people face in acquiring them and/or that the health services face in effectively helping them to adapt. These findings may influence the quality of life of elderly with hearing impairment, given the association with probable dementia revealed by this study.

Common bean grown in no-tillage (NT) systems has increased markedly in Brazil. Thus, to optimize the fertilizer recommendations, it is important to know the nutritional requirements of this crop when grown under new and established NT systems, which can change the nutrient availability and crop response to nitrogen (N) fertilization. The objective was to evaluate the extraction and exportation of nutrients by common bean as function of N fertilization on soil under new and established NT systems. The experiment was carried out in two agricultural years, on a Red Nitosol (Alfisol) in Botucatu, São Paulo State, Brazil. A randomized complete block design was used in a split-plot scheme with four replications. The plots consisted of areas under NT systems after different periods of adoption and the subplots of four forms of N application to common bean (T0: control, without nitrogen; T1: 60 kg ha-1 before sowing; T2: 60 kg ha-1 sidedressed at V4 stage; and T3: 60 kg ha-1 before sowing + 60 kg ha-1 sidedressed). The following properties were evaluated: shoot dry matter, nutrient concentration and accumulation in the shoot, grain yield, and nutrient concentration and exportation in the grains. The NT age did not affect common bean yield, nutrition and response to N management. Nitrogen application, especially before sowing, led to higher dry matter and nutrient accumulation by common bean. The nutrient concentration in grains was little influenced by N fertilization. Grain yield and nutrient exportation were highest after double N application (before sowing and sidedressed) or only sidedressed at V4.
