1. Replacement of wheat bran with spineless cactus in sugarcane-based diets for steers
ABSTRACT The effect of replacing wheat bran with spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on the intake of nutrients, feeding behavior, and rumen digestibility of steers was assessed using digested samples collected from the omasum. Five crossbred steers (1/2 Holstein-Zebu) were fitted with cannulas in the rumen and then assigned

2. Intake and digestibility of silages containing pineapple pulp and coast-cross hay with or without urea and markers recovery in sheep
ABSTRACT The objective of this study was to evaluate the intake and digestibility of silages containing pineapple pulp and coast-cross hay, with or without addition of urea, and the recovery of the markers chromium oxide (Cr2O3), indigestible neutral detergent fiber (iNDF), indigestible acid detergent fiber (iADF), and indigestible dry matter (iDM), in a dig

3. Simulation and validation of the ruminal digestion of carbohydrates in cattle from kinetic parameters obtained by in vitro gas production technique
This study aimed to validate the estimates of the ruminal degradation of total carbohydrates (TC), ruminal and total digestion of fibrous carbohydrates (FC) and microbial nitrogen flow in the abomasum evaluated by in vitro gas production technique (IVGP). Six ruminally and abomasally cannulated steers arranged in a double 3 × 3 latin square were used to mea

4. Indicators and collection methodology evaluations to estimate the nutrients digestibility on Buffaloes / Avaliação de indicadores e metodologia de coleta para estimativa da digestibilidade de nutrientes em bubalinos
Dry fecal matter production has been estimated from neutral detergent indicators on indigestible fiber (iNDF), acid detergent fiber (iADF), indigestible dry matter (DMi), that were incubated for 144 hours and 288 hours, as well as chromium oxide (Cr2O3) and purified isolated lignin and enriched (LIPE) in two sampling schemes (3 and 5 days) on buffaloes. Five

5. Influência da velocidade cross-flow na câmara de flotação na eficiência de unidades de flotação por ar dissolvido tratando água para abastecimento / The influence of cross-flow velocity in the flotation chamber on efficiency of a dissolved air flotation unit treating drinking water
O reator de FAD deve propiciar condições adequadas para contato entre as micro-bolhas e os flocos formados no pré-tratamento e também condições para que o conjunto floco/bolha possa ser direcionado ao topo do reator, e assim ser removido. O projeto de pesquisa visou estudar condições hidrodinâmicas proporcionadas pela variação da Velocidade Cross-

6. Efeito do Fornecimento Crônico de Leptina e da Nutrição na Maturação Sexual de Novilhas Zebuínas (Bos taurus indicus) / Effect of Chronic Leptin Administration on Sexual Maturation of Zebu Heifers (Bos taurus indicus)
This study was carried out to evaluate the effects of chronic administration of recombinant ovine leptin (oLeptin) and the energy level of the diet on age, body weight (BW), body condition score (BCS) and body composition at puberty, as well as to evaluate its effects on dominant follicle (DF) development and dry matter (DM) intake. Thirty six Nellore heifer

7. Wastewater post-treatment with submerged aerated biofilter filled with granular coal: technical performance and economic viability study / Pós-tratamento de esgoto sanitário com biofiltro aerado submerso preenchido com carvão granular: desempenho técnico e estudo de viabilidade econômica
Neste trabalho avaliou-se o desempenho técnico e a viabilidade econômica do biofiltro aerado submerso preenchido com carvão granular antracitoso, empregado no pós-tratamento de efluente proveniente de reator anaeróbio de fluxo ascendente com manta de lodo. Os biofiltros experimentais utilizados no trabalho, com volume reacional de 47 L, operaram por 200

9. Reator de leito expandido em escala plena com zonas anaeróbia e aeróbia sobrepostas: remoção conjunta de matéria orgânica e nutrientes e estudo do comportamento microbiológico do biofilme, por respirometria e microsensor de OD / Full scale expanded bed reactor with overlaid anaerobic and aerobic zones: joint removal of organic matter and nutrients and the study of microbiological biofilm behavior and DO microsensor
The current research aimed the development of a 159 M POT.3total volume biological reactor, with a expanded and partially aerated granular coal bed (activated and anthracite), to promote organic matter and nutrients (N and P) removal from wastewater due to the maintenance of anaerobic and aerobic environments, stratified throughout the height of the reactor

10. Multiple invasion percolation / Percolação por invasão múltipla.
We generalize the standard site invasion percolation model to permit simultaneous invasion of several sites. We propose two kinds of generalizations: one in which the invasion flux is controlled by the perimeter size and another where the scaling properties command the growth process. The acceptance profile as well as the fractal dimension D IND.Fare careful

11. Genotypic and Phenotypic Characterization of the Drosophila Melanogaster Olfactory Mutation Indifferent
Two Drosophila melanogaster third chromosomes carrying the EMS-induced mutations IndifferentA (IndfA) and IndifferentB (IndfB), previously isolated from larvae showing an anosmia when stimulated with nonanol, were recombined with a multi-marked chromosome in order to localize the mutant character(s). Recombinant strains were tested for their larval olfactory
