Composição química e degradabilidade ruminal de silagens da cana-de-açúcar tratada com aditivos químicos e bacteriano1

The objective of this trial was to evaluate the effect of the addition of chemical and bacterial additive in the ensiling of sugar cane (Saccharum officinarum L.) on chemical composition, pH, kinectic fraction and in situ degradation of nutritions components of silages. Five rumen-cannulated 1/2 Simental + 1/2 Zebu steers were allotted to a completely randomized design. The steers were placed in individual cages and they were fed with diets with 76% forage (%DM). Five silages were evaluated: control - sugar cane, no additives; urea - sugar cane + 0.5% of urea (wet basis); inoculant - sugar cane inoculated with LactoSilo® (390 g/40 t forage); NaOH - sugar cane + 1.0% of sodium hydroxide (wet basis); CaOH - sugar cane + 0.6% of calcium hydroxide (wet basis). The silage additives with sodium hydroxide showed the highest pH values before (11.20) and after (4.87) for silage. No differences were observed among the silages for dry matter (26.85), crude protein (5.25) and acid detergent fiber (57.21). Fractionation of dry matter and organic matter of silages showed similar behavior, with higher values of the soluble fraction (fraction A) for silages with sodium hydroxide (45.86 and 30.95%) and calcium hydroxide (29.47 and 26.13%). The use of sodium hydroxide allowed obtaining higher values for the degradation of cell wall components of silages from cane sugar. The potencial and effective degradability with 3, 5 and 8%/h of passage rate were respectively 88.44, 64.45, 56.73 and 49.83% for NDF and 82.57, 55.51, 46.72 and 38.83% for ADF, indicating that the use of sodium hydroxide as chemical additives can improve the nutritive value of cane sugar silage.

Composição florística de angiospermas no carste do Alto São Francisco, Minas Gerais, Brasil

The occurence of carbonatic rocks defines a typical type of relief, called karst, that, by its geomorphology and hydrology, usually differs from the surrounding landscape. In the upper São Francisco river basin, some striking remnants of vegetation associated to karst can be found, which are locally knwon as Mata de Pains. In this region, a mosaic of different physiognomies, including forests and open areas, which present noteworthy plant diversity, composes the vegetation. The aim of this study is to provide an inventory of angiosperm species in areas of carbonatic rocks outcrops in the upper São Francisco river basin karst region, as well as analyze the floristic relationship of the study area with different Brazilian phytogeographic domains. Fieldwork was performed during the period of 2002 a 2006, when collections of fertile speciemns were done in areas associated to carbonatic rock outcrops. During the study, 1512 exsicates were incorporated to BHCB herbarium collection. A total of 456 angiosperm species were inventoried, distributed in 299 genera and 77 families. Herbaceous habit was better represented, with 161 species, followed by shrubs and trees (111 species each) and lianas (73 species). The flora of the study area presents more influence of the Mata Atlântica domain (Atlantic Rain Forest), followed by, in order of importance, Cerrado, Amazonia, Caatinga, Pantanal and Pampa. Floristic surveys in different karst regions inserted in different phytogeographic domains may, together, provide useful information in understanding the phytogeografic history of Neotropical vegetation.

Relação entre idade cronológica, indicadores de adiposidade corporal e aptidão física relacionada à saúde em meninos e meninas

Objectives. The purpose of this study was to analyze the relationship between adiposity indicators, age and physical fitness related to health. Methods. The sample involved 43 boys and 53 girls. The tests applied were: the Sit-up (S), Modified Pull-up (MP) and Run/Walk (RW) tests. Fat indicators were: Body Mass Index (BMI), subscapular (SB), triceps (TR), and calf (C) skinfolds; the skinfolds sum (Σ) and percentage of fat mass (%F). Results. The results indicated negative correlation between MP and TR, MC, Σ and %F for boys and girls (r = -0,42 a r = -0,52, P ≤ 0,01). There was positive correlation among the S test and age for both groups (r = 0,35, P ≤ 0,05 a r = 0,52, P ≤ 0,01), and negative on the S test with SB, MC and %F for the girls (r = -0,28 a r = -0,29, P ≤ 0,05). Negative correlation also was verified between RW with TR for the boys (r = -0,30, P < 0,05). Conclusion. Age seemed to be related with better performance, and adiposity with weaker performance, mostly in the MP where it is necessary to support their own body mass. Thus, these factors should be considered in the interpretation of results and when establishing criteria for health-related tests with these characteristics. © 2013 Revista Andaluza de Medicina del Deporte.

Composição de cores através da calibração radiométrica e fotométrica de LEDs: Teoria e experimento

In the present work, the basic concepts of radiometric, photometric and colorimetric calibration are presented, which were applied to three light-emitting diodes (LEDs) used to compose the different color sensations that the human eye perceives in the visible region of the electromagnetic spectrum. In this sense, an experimental setup comprising a LED drive circuit and a home-made integrating sphere was assembled for the initial radiometric and photometric calibration as well as to obtain a set of intensity and spectral combinations associated to different colorimetric CIE (Commission Internationale de l'Eclairage) coordinates. The reader can, therefore, understand, in a simple manner, the process of color composition inside a color monitor or display picture element (pixel ). © Sociedade Brasileira de Física.
