Abstract: this article presents a study on biogas production from wastewater cassava considering the volume of a one-phase horizontal tubular flow reactor. the objective was to evaluate the biogas production, enlarging the organic loadings and feeding volums, resulting in minor hydraulic retention times (hrt). the reactor was continuously fed with organic charges corresponding to 1.18; 1.28; 1.57 and 2.68 g cod l-1r d-1 (grams of oxygen chemical demand per liter of reactor per day), resulting in hydraulic retention times 15; 13; 8.3 and 6.6 days. the correspondent specific biogas productions were, respectively, 0.52; 0.41; 0.65 and 0.63 l l-1rd-1 , emphasizing that the 13-day was the first hrt rated, followed by 8.3, 6.6 and 15 days. it was concluded that with the hrt decrease occurred larger biogas production per reactor volume. therefore, with the correct selection for hrt, it is possible to make the best of the reactor volume, resulting in economy at the technology implantation in cassava starch industries.
Aproxima es entre literatura e cinematografia: Análise da convergência e da divergência entre as cadeias significantes do livro e do filme O Pequeno Príncipe
Carla Simone Doyle Torres
Revista Tecer , 2011,
Abstract: Entre a obra literária e sua vers o cinematográfica há adapta es. Quando sons, cores e luzes, falas, enquadramentos, gestos e movimentos devem contar a história, articulam-se aproxima es e afastamentos em rela o às cadeias significantes de sua correspondente no mundo das letras. Pelo método do comparativismo, este trabalho identifica em O Pequeno Príncipe exemplos de convergência e de divergência entre as cadeias significantes das vers es literária e cinematográfica da obra. De modo geral, as análises apontam que trechos literários com descri es muito pormenorizadas s o de difícil transposi o para a narrativa fílmica. Além disso, plots com menores implica es no conjunto da narrativa s o mais facilmente descartados na vers o cinematográfica. A quest o temporal também obriga o filme a determinados cortes em rela o à narrativa literária, sem que o sentido geral da obra seja alterado.

Abstract: records of 844 animals of a f2 swine population were used to evaluate the association among four performance traits (litter size at birth, teat number, weight at 77 days of age, feed intake and feed:gain ratio from 77 to 105 days of age) and 17 carcass traits (slaughter age, right side carcass weight, carcass length by the brazilian carcass classification method, backfat thickness at boston shoulder area and the midline, loin depth, heart, spleen, kidney, cold right side carcass, ham, boston shoulder, picnic shoulder, loin (bone-in), spareribs, jowl and sirloin weights) using canonical correlation analysis. the first canonical correlation (r) was 0.7804, indicating performance and carcass traits were not independent. the first two canonical variable pairs were statistically significant. in the first canonical variable pair, weight at 77 days of age and slaughter age were the absolute predominant traits. these results suggest larger weight at 77 days indicates reduced age at slaughter.

Revista Brasileira de Zootecnia , 2005, DOI: 10.1590/S1516-35982005000700007
Abstract: principal component analyses were applied to carcass records of 367 animals of a f2 swine population. starting from 33 traits, 17 showed variation lower than 0.7 (eigenvalue lower than 0.7) and significant simple linear correlations with the other traits, indicating they were redundant. these results suggest the following variables to be used in future carcass studies: slaughter age; right side carcass weight; carcass length by the brazilian method of carcass classification; higher backfat thickness at boston shoulder area and in the midline; loin depth; spleen, heart, cold right side carcass, ham, boston shoulder, picnic shoulder, loin (bone-in), spareribs, jowl, sirloin and kidney weights.

Abstract: data from 326 animals of a f2 swine population were used to select traits related to meat quality by principal components analysis. the following traits were considered: ph at 45 minutes post mortem (ph45), ph at 24 hours post mortem (phu), drip loss (dl), cooking loss (cl), total loss (tl), intramuscular fat (imf), objective tenderness (ot), lightness (l), redness (a) and yellowness (b). variation lower than 0.7 (eigenvalue lower than 0.7) indicated four traits, which were significantly correlated to the other traits, to be discarded. these results suggest the use of ph45, phu, l, a, imf and cl as swine meat quality traits in future experiments.

Abstract: data comprising 68,523 test day milk yield of 8,536 cows of the holstein breed, daughters of 537 sires, distributed in 266 herds, calving from 1996 to 2001, were used to compare random regression models, for estimating variance. test day records (td) were analyzed by different random regression models regarding the function used to describe the trajectory of the lactation curve of the animals. legendre orthogonal polynomials function of second, third and fourth order were used. the random regression models included the effects of herd-month-year of the control, genetic group of the animals; the frequency of the daily milk; regression coefficients for each class of age-season (in order to describe the fixed part of the lactation curve) and random regression coefficients related to the direct genetic and the permanent environmental effects. the heritability estimates obtained using the random regression models ranged from 0.122 to 0.291. the random regression model which used the fourth order legendre polynomials was the model which better described the genetic variation of the milk yield, according to aic test.

Abstract: data comprising 68,523 test day milk yield of 8,536 cows of the holstein breed, calving from 1996 to 2001, were used to compare random regression models, for estimating variance components. test day records (td) were analyzed as multiple traits, considering each td as a different trait. the test day records were analyzed as longitudinal traits by different random regression models regarding the function used to describe the trajectory of the lactation curve of the animals. the wilmink's exponential function, the ali and schaeffer logarithmic function and the legendre orthogonal polynomials of second and fourth order were used. the comparisons among the models were based on the following criteria: estimates of variance components of the multiple-trait model and random regressions models, values of residual variance and values of the logarithms of the likelihood functions. the heritability estimates obtained using the multiple-trait model varied from 0.110 to 0.244, for the random regression models the values ranged from 0.127 to 0.301, being the largest estimates observed in the models with larger number of parameters. the random regression models which used the legendre polynomials was the model which better described the genetic variation of the milk yield.

Physics , 1994,
Abstract: After the detection of structure in the microwave sky, the characterization of the observed features may be a useful guide to current and future experiments. The first year COBE-DMR sky maps were analyzed in order to identify the most significant hot and cold spots. The statistical significance of potential spots of cosmic origin was evaluated with Monte Carlo simulations. The area, eccentricity, and location of the most significant spots are given.

Abstract: jacaranda decurrens (bignoniaceae) is an endemic species of the cerrado with validated antitumoral activity. the genetic diversity of six populations of j. decurrens located in the state of s?o paulo was determined in this study by using molecular markers for randomly amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp). following optimization of the amplification reaction, 10 selected primers generated 78 reproducible rapd fragments that were mostly (69.2%) polymorphic. two hundred and five reproducible aflp fragments were generated by using four selected primer combinations; 46.3% of these fragments were polymorphic, indicating a considerable level of genetic diversity. analysis of molecular variance (amova) using these two groups of markers indicated that variability was strongly structured amongst populations. the unweighted pair group method with arithmatic mean (upgma) and pearson's correlation coefficient (rapd -0.16, p = 0.2082; aflp 0.37, p = 0.1006) between genetic matrices and geographic distances suggested that the population structure followed an island model in which a single population of infinite size gave rise to the current populations of j. decurrens, independently of their spatial position. the results of this study indicate that rapd and aflp markers were similarly efficient in measuring the genetic variability amongst natural populations of j. decurrens. these data may be useful for developing strategies for the preservation of this medicinal species in the cerrado.
