Comportamento ingestivo de cordeiros em confinamento, alimentados com dieta exclusiva de concentrado com diferentes porcentagens de proteína

The experiment was conducted to evaluate the ingestive behavior of feedlot lambs fed with an exclusive diet of concentrate with different percentages of protein (14, 16, 18, and 20%). A total of twenty four Santa Inês crossbred lambs, not castrated, with approximately 180 days of age, average live weight of 25kg, confined, in a completely randomized design, with four treatments and six repetitions. The time spent on feeding decreased linearly in 0.20 hours/day for each 1% increasing in protein percentage in the diet, the idleness increased linearly in 0.25 hours/day, and the total chewing decreased linearly in 0.25 hours/day. The increase in the protein percentage in the diet increased the feed efficiency linearly (kg DM and NDF/hour) in 0.038 and 0.005kg/hour, respectively, for DM and NDF fractions. However, the intake of dry matter (DM) and neutral detergent fiber (NDF), the rumination efficiency (kg DM and NDF/hour), as well as the period (nº /day) and the time (min) spent on feeding, ruminating and idling were not influenced by different protein percentages in the diet.

Effect of concurrent training on risk factors and hepatic steatosis in obese adolescents

OBJETIVOAnalisar os efeitos de 20 semanas de treinamento concorrente sobre as variáveis de composição corporal, perfil lipídico e diagnóstico da esteatose hepática em adolescentes obesos.MÉTODOSRealizou-se um ensaio clínico aberto com 34 adolescentes obesos com idades entre 12 e 15 anos. Foram analisados gordura corporal total e de tronco, colesterol total e suas frações (HDL, LDL e VLDL) e triglicérides, sendo realizado exame de ultrassonografia de abdome superior para diagnosticar esteatose hepática. Os participantes foram submetidos ao treinamento concorrente (associação de treino com pesos e exercício aeróbio) três vezes por semana, com duração de uma hora-aula durante 20 semanas. Para o tratamento estatístico, foram realizados o teste t de Student pareado e a análise de frequência, a fim de verificar as reduções relativa e absoluta do diagnóstico da esteatose hepática, adotando-se p<0,05.RESULTADOSOs adolescentes estudados apresentaram melhoras significativas da composição corporal, com diminuição do percentual de gordura total, da massa gorda total, da gordura de tronco e do aumento da massa magra, além de redução do tamanho dos lóbulos do fígado, dos índices de prevalência da esteatose hepática, do colesterol total e LDL-colesterol.CONCLUSÕESO treinamento concorrente foi efetivo por promover melhorias significativas de variáveis da composição corporal e do perfil lipídico, além de reduzir a prevalência da esteatose hepática.

Fractionation of aquatic humic substances and dynamic of chromium species in an aquatic body influenced by sugarcane cultivation

This study had as main objectiveto evaluate the influence of AHS obtained from an area under sugarcane cultivation on the dynamics of chromium species (Cr(III) and Cr(VI)). Was studied complexing capacity (CC) with the AHS of chromium species and these were characterized using UV/Vis spectrophotometry, molecular fluorescence, elemental analysis and infrared. AHS with and without fractionation showed a greater aromaticity degree and a predominance of humic acids, and the E4/E6 and E2/E4 ratios suggested aromatic rings and a greater contribution from plants, which indicates lignin structures. The highest CCs were observed for the AHS fractionated, being fraction with molecular-size < 10 kDa and 10-30 kDa showed the highest ability to complex Cr(III) and Cr(VI) ions, respectively. These results are corroborating with C/H/N and UV/Vis data, where we can conclude that the AHS without fractionation had the greatest aromaticity and a predominance of humic acids in their structure.

Modelagem geoestatística das incertezas da distribuição espacial do fósforo disponível no solo, em área de cana-de-açúcar

Phosphorus is one of the limiting nutrients for sugarcane development in Brazilian soils. The spatial variability of this nutrient is great, defined by the properties that control its adsorption and desorption reactions. Spatial estimates to characterize this variability are based on geostatistical interpolation. However, inherent uncertainties in the procedure of these estimates are related to the variability structure of the property under study and the sample configuration of the area. Thus, the assessment of the uncertainty of estimates associated with the spatial distribution of available P (Plabile) is decisive to optimize the use of phosphate fertilizers. The purpose of this study was to evaluate the performance of sequential Gaussian simulation (sGs) and ordinary kriging (OK) in the modeling of uncertainty in available P estimates. A sampling grid with 626 points was established in a 200-ha experimental sugarcane field in Tabapuã, São Paulo State. The sGs algorithm generated 200 realizations. The sGs realizations reproduced the statistics and the distribution of the sample data. The G statistic (0.81) indicated good agreement between the values of simulated and observed fractions. The sGs realizations preserved the spatial variability of Plabile without the smoothing effect of the OK map. The accuracy in the reproduction of the variogram of the sample data obtained by the sGs realizations was on average 240 times higher than that obtained by OK. The uncertainty map, obtained by OK, showed less variation in the study area than that obtained by sGs. Thus, the evaluation of uncertainties by sGs was more informative and can be used to define and delimit specific management areas more precisely.

Determination of reactivity rates of silicate particle-size fractions

The efficiency of sources used for soil acidity correction depends on reactivity rate (RR) and neutralization power (NP), indicated by effective calcium carbonate (ECC). Few studies establish relative efficiency of reactivity (RER) for silicate particle-size fractions, therefore, the RER applied for lime are used. This study aimed to evaluate the reactivity of silicate materials affected by particle size throughout incubation periods in comparison to lime, and to calculate the RER for silicate particle-size fractions. Six correction sources were evaluated: three slags from distinct origins, dolomitic and calcitic lime separated into four particle-size fractions (2, 0.84, 0.30 and <0.30-mm sieves), and wollastonite, as an additional treatment. The treatments were applied to three soils with different texture classes. The dose of neutralizing material (calcium and magnesium oxides) was applied at equal quantities, and the only variation was the particle-size material. After a 90-day incubation period, the RER was calculated for each particle-size fraction, as well as the RR and ECC of each source. The neutralization of soil acidity of the same particle-size fraction for different sources showed distinct solubility and a distinct reaction between silicates and lime. The RER for slag were higher than the limits established by Brazilian legislation, indicating that the method used for limes should not be used for the slags studied here.

A violência da escola na voz de futuros professores: uma probabilidade da produção da cultura da violência em ambientes escolares?

The purpose of this research is to show the types of violence committed by teachers that were experienced and/or witnessed by future teachers during their schooling history. It's a quantitative and qualitative research. The collection, organization, and analysis of data proceeded from Content Analysis (BARDIN, 1977) and the construction of Bernard Charlot and Pierre Bourdieu's works and specific literature on the theme. The subjects are 12 students that attended the Pedagogy undergraduate program in 2011 at the Faculty of Science and Arts of the city of Araraquara in the state of São Paulo, Brazil. The data shows that the majority of the group of individuals claimed to have witnessed or experienced violence by teachers during their basic training. According to them, among the most recurring types of violence are those of symbolic nature. They attended, not equally, the public system and the private system. This enabled pointing out that violence, especially symbolic violence, occurred in both school systems. Therefore, this is a phenomenon that affects different fractions of social classes. Considering that the participants of this research are future teachers, it was established a relation with the notion of 'cycle of abuse', since there is a high possibility of them practicing the teaching function.
