Características agronômicas e bromatolôgicas do milho submetido a adubações com potássio na produção de silagem

The aim was to evaluate levels and forms of application of potassium on the agronomic and alimentary characteristics of corn used for silage. The experiment was carried out at UNIFENAS during the agricultural year of 2008/2009. Fertilization at planting and sowing was performed manually using 120kg ha-1 P2O5 and 30kg ha-1 N, the potassium being applied according to the treatments. The experimental design used was of randomized blocks in a 4 x 2 factorial arrangement with four replications, using four amounts (0; 60; 90 and 120 kg ha-1) and two formsof application of K (100% at planting and 50% at sowing+50% coverage). The interaction between the factors of amount and forms of application of the potassium was not significant (p>0.05) for the variables studied: the main effect of each factor was then investigated. There was no effect (p>0.05) for K levels on the percentage of drymatter (DM) and bedded plants, DM and grain productivity and grain participation in the mass. The highest grain yield was obtained when using K at planting (p<0.05). High doses of potassium did not produce changes in DM, percentage of bedded plants, DM production, grain yield or grain percentage of the plant. The different levels and forms of application of potassium do not alter the alimentary characteristics of corn silage.

Características aeróbias e anaeróbias de mesatenistas brasileiros treinados

O objetivo deste estudo foi determinar, em mesatenistas bem treinados, as aptidões aeróbia e anaeróbia. Participaram do presente estudo oito mesatenistas brasileiros treinados do sexo masculino (18±2 anos). Os sujeitos foram submetidos a um teste incremental específico para determinação do consumo pico de oxigênio (VO2PICO), intensidade associada ao VO2PICO (iVO2PICO) e do ponto de compensação respiratório (PCR) e a dois testes de esforço repetitivo, sendo o teste de RAST e o índice anaeróbio alático (IAA), para determinação dos índices anaeróbios. O VO2PICO correspondeu a 50,5±4,4ml kg-1 min-1 , a iVO2PICO a 52,1±9,6 bolas min-1 e o PCR a 44,9±8,0 bolas min-1. No RAST, a potência pico (PP) e a potência média (PM) relativa corresponderam a 9,0±1,3W kg-1 e 7,0±0,9W kg-1, respectivamente, enquanto que o IAA foi 1,14±0,51 mM/m s-1 . Esses valores de VO2PICO e dos parâmetros anaeróbios quando comparados a valores de outros esportes com raquetes caracterizaram que mesatenistas brasileiros treinados apresentam potência aeróbia moderada e potência anaeróbia é baixa.

Frequência de ocorrência de cavidade anoftálmica na região centro-oeste paulista e características dos portadores

Purpose: To observe the frequency of the occurrence of the anophthalmic socket in the Middle West region of the state of São Paulo and to describe the demographic profile of the carriers in a population-based data. Methods: A cross-sectional study involve a random sampling carried out in twelve cities of the Middle West region of the state of São Paulo, for which the reference center is the city of Botucatu was done. The participators were chosen by assortment which considered the houses of these people. It was established a sampling with 11,453 people. All the exams were realized using a Mobile Ophthalmologic Unit. The research protocol included the demographic data and the complete ophthalmologic exam (anamnesis, ocular and systemic antecedents, familiar antecedents, visual acuity with and without correction, tonometry, biomicroscopy, fundoscopy, and refraction exam). All the data were transferred to an Excel spreadsheet and submitted to a descriptive analysis and were presented by the frequency of the occurrence. Results: Ophthalmic socket frequency in the Middle West region of the state of São Paulo was 0.96%. We found 11 cases of anophthalmic socket, with involvement of 0.7 % in females and 1.3 %, male. The most common causes of anophthalmic socket were glaucoma (blind painful eye), microphthalmia, trauma, and endophthalmitis. The majority of the people were 40 years old or more, and we found just one person younger than 19 years old. Conclusion: The anophthalmic socket occurred in 0.96% of the habitants of the Middle West region of São Paulo State, occurring mainly in male and with large variety of the affected ages.
