Comprimento total do intestino em Bubalus bubalis (Linnaeus, 1758)

Os autores estudando o comprimento total do intestino, bem como de seus diversos segmentos, em 20 búfalos de raça não definida, 10 machos e 10 fêmeas, encontraram os seguintes valores:intestino delgado ................................... 27,12 ± 1,74 mceco ...................................................... 0,43 ±  0,05 mcólon e reto ............................................ 7,70 ±  0,53 mintestino grosso ....................................... 8,13 ±  0,58 mcomprimento total ................................. 32,25 ±  2,03 mOs resultados, quando submetidos a tratamento estatístico, não demonstraram existir diferenças significantes relativamente aos sexos e, tampouco, correlação entre as dimensões de todo o tubo entérico e os pesos ou comprimento das carcaças.The length of the various enteric segments as well as the intestine in its total length were studied in 20 adults buffaloes (10 males and 10 females).The results obtained were:small intestine ............................... .27.12 m ± 1.74cecum ..............................................

Capacidade do rume em bovinos azebuados. III

The capacity of the rumen (paunch) was determined in two lots of 20 Zebu cattle (Nelore breed), all male, by emptying this compartment of the stomach, then filling it with water. Measuring the water volume thus contained, they was found that, -the average capacity of the rumen in animals with four (35.5 months) and six (43.5 months) permanent teeth was found, respectively, equal to 79.36± 0.75 I and 88.65 ±1,68 I. Both, the correlation between rumen capacity and carcass length (measured from the junction of the seventh cervical and the first thoracic vertebrae to the lumbo-sacral junction) and the correlation between rumen capacity and carcass weight (excluding the head), were statistically significant. The capacity difference of the rumen in the two bovine lots was also found to be significant.Pesquisa sobre a capacidade do rume em dois lotes de 20 bovinos anelorados, machos, portadores de quatro (35,5 meses) e seis (43,5 meses) dentes permanentes. Apurou-se para o primeiro grupo de animais a média de 79,36 ± 0,75 I, e, para o segundo, a média de 88,65 ± 1,68 I. Os coeficientes de correlação entre capacidade do rume e comprimento da carcaça e, entre capacidade do rume e peso da carcaça revelaram-se estatisticamente significantes. As médias correspondentes aqueles grupos também diferiram significantemente

Capacidade dos reservatórios gástricos de bovinos azebuados. I. Capacidade do rume em bovinos azebuados machos adultos (acima dos 49,9 meses)

Determinou-se a capacidade do rume em 20 bovinos anelorados, machos, adultos (acima dos 49,9 meses de idade), encontrando-se como média 97,13 ± 2,30 1.Os coeficientes de correlação entre capacidade do rume e comprimento da carcaça e entre capacidade do rume e peso da carcaça mostram-se estatisticamente significantes.The capacity of the rumen (paunch) was determined in a lot of 20 Zebu cattle (Nelore breed), adult (over 49,9 months), males, by emptying this compartment of the stomach, then filling him with and under water and measuring thus contained. The authors found that the average capacity of the rumen is 97,13 ± 2,30l

Effect of Texture of AZ31 Magnesium Alloy Sheet on Mechanical Properties and Formability at High Strain Rate

The mechanical properties and formability of AZ31 magnesium alloy strips having different textures were investigated at a high strain rate based on that occuring in mass production by press forming. Forming at a high strain rate on the order of 10 0 s À1 requires a high temperature of over 473 K. To obtain accurate stress-strain curves, a high-speed testing machine that can maintain a constant true strain rate was used, and the change in gauge length on a test piece in a furnace was measured during the testing time of about 0.5 s. For the specimens, rolled strips consisting of fine grains (about 10 mm) and an extruded strip consisting of coarse grains (about 40 mm) were used. The {0001} textures of the extruded strip and one of the rolled strips were strongly oriented parallel to the rolled surface, but the texture of another rolling strip had two peaks that were inclined at 5 $15 deg in front of and behind the rolling direction. At the high strain rate of 10 0 s À1 , elongation decreased for every specimen. Nevertheless, a limiting drawing ratio (LDR) of 2:1$ 2:2 was obtained under uniform heating above 503 K in all the specimens except for the extruded strip. The high LDR of the rolled strip having a two-peak texture was maintained in forming at temperatures down to 473 K, in contrast to the LDR of the strongly oriented rolled strip, which reduced rapidly when formed at temperatures less than 503 K

Liga de Prevenção à Cegueira – 29 anos de ensino, pesquisa e assistência em oftalmologia

Uma parcela significante das doenças sistêmicas mais prevalentes em nosso meio vem acompanhada de acometimento ocular e muitas doenças oftalmológicas exigem atendimento imediato e cuidados específicos para evitar-se a cegueira. O curso de Oftalmologia da graduação abrange os temas essenciais à adequada formação do médico generalista, porém carece de treinamento prático e cirúrgico. A fim de suprir tal deficiência, a Liga de Prevenção à Cegueira foi fundada em 1985 como alternativa para aprofundar os conhecimentos na área, aproximar-se da prática oftalmológica e atender indagações profissionais futuras.
