Este trabalho teve como objetivo avaliar o efeito da substituição do amido pré-gelatinizado por amido resistente no metabolismo de lipídeos e de carboidratos em ratos machos Wistar. 20 ratos machos foram divididos em dois grupos, um grupo recebeu uma dieta com 9,5% (DAP) e o outro grupo com 18,1% (DAR) de amido resistente durante 22 dias. Foram analisados peso, consumo de ração e água, e quantificadas as concentrações de colesterol e de triglicerídeos no soro e no músculo, e de glicogênio hepático e muscular. Os dados foram analisados por teste de Tukey (p>0,05) e gráficos box-plot. Não houve diferenças significativas na ingestão de ração e água, mas os animais do grupo DAP apresentaram aumento de peso (51,12g para 55,27g) enquanto os do grupo DAR diminuíram (49,01g para 44,15g). O grupo DAR apresentou diminuição de triglicérideos, colesterol total no soro (de 125,761 mg/dL para 104,874 mg/dL) e do glicogênio muscular, mas aumento de triglicerídeos no músculo gastrocnêmio em comparação com o grupo DAP (de 0,160 mg/dL para 0,259 mg/dL). Estes resultados apontam para a diminuição na velocidade de absorção da glicose no grupo de animais com dieta com maior quantidade de amido resistente, que pode ter induzido diminuição nos processos de síntese de triglicérideos e de colesterol levando ao aumento do catabolismo destes substratos pelo organismo, e adaptação plástica dos músculos para utilização de ácidos graxos no seu metabolismo oxidativo.

Code refactoring is the modification of structure with out altering its functionality. The refactoring task is critical for enhancing the qualities for non-functional attributes, such as efficiency, understandability, reusability, and flexibility. Our research aims to build an optimized model for refactoring prediction at the method level with 7 ensemble techniques and verities of SMOTE techniques. This research has considered 5 open source java projects to investigate the accuracy of our anticipated model, which forecasts refactoring applicants by the use of ensemble techniques (BAG-KNN, BAG-DT, BAG-LOGR, ADABST, EXTC, RANF, GRDBST). Data imbalance issues are handled using 3 sampling techniques (SMOTE, BLSMOTE, SVSMOTE) to improve refactoring prediction efficiency and also focused all features and significant features. The mean accuracy of the classifiers like BAG- DT is 99.53% ,RANF is 99.55%, and EXTC is 99.59. The mean accuracy of the BLSMOTE is 97.21%. The performance of classifiers and sampling techniques are shown in terms of the box-plot diagram.

<p>Este artigo mostra o resultado da aplicação do método estatístico denominado Box Plot, cuja finalidade é a identificação de anos padrão secos, chuvosos e habituais, sendo para tanto, analisados os dados pluviométricos da série histórica 1980-2012. Devido à carência de metodologia específica para a climatologia, há a necessidade de se buscar métodos apropriados cuja contribuição é fundamental para se analisar e compreender a variabilidade das chuvas. A utilização de anos excepcionais é importante por contribuir com o entendimento das possíveis variabilidades que ocorrem na circulação atmosférica e que refletem nos tipos de tempo dos anos secos e chuvosos. Portanto, objetiva-se espacializar a distribuição pluviométrica em anos tidos enquanto excepcionais a fim de demonstrar a importância do método estatístico na identificação da variabilidade pluviométrica.</p>

Objetivou-se quantificar o CO2,atributos químicos e físicos do solo são influenciados por diferentes manejos de preparo do solo. O Delineamento experimental adotado foi inteiramente casualizado, sendo os tratamentos: Sistema de Plantio Direto (SPD), Cultivo Mínimo e Preparo Convencional (PC), e como referência: área de vegetação nativa (Mata), contando com seis repetições cada variável de estudo. Além da comparação por teste médias, foi realizada uma análise exploratória das leituras nos sistemas de preparo do solo, onde o CO2 foi traduzido graficamente num diagrama o box-plot. As variáveis avaliadas foram: CO2 obtido por meio de um analisador de gás infravermelho; os atributos físicos do solo: Densidade do solo (Ds), Volume Total de Poros (VTP), Macroporosidade (Ma), Microporosidade (Mi), Resistência a Penetração do solo (RPS) e o atributo químico: carbono orgânico total (COT). O fluxo CO2 do solo apresentou diferença significativa entre o SPD e o PC; valores médios encontrados para SPD, CM, Mata e PC foram 2,30; 2,25; 2,18; e 1,39 μmolCO2m−2 s−1, respectivamente; o COT apresentou seu maior valor na área de Mata (32,95 gkg-1) diferindo estatisticamente das demais áreas. Observou-se uma menor emissão de CO2 do solo no PC, pois o sistema apresenta baixo aporte de carbono orgânico.Palavras-chave: sistema de preparo convencional; cultivo mínimo; preparo convencional; carbono orgânico total. CO2 EMISSION, PHYSICAL ATTRIBUTES AND TOTAL ORGANIC CARBON IN DIFFERENT SOIL PREPARATION SYSTEMS ABSTRACT: The objective was to quantify the CO2, chemical and physical attributes of the soil are influenced by different management of soil preparation. The experimental design was completely randomized, with the treatments: no-tillage (NT), minimum tillage (MT) and conventional tillage (CT), and as reference:  native forest (NF), with six replicates each study variable. In addition to the mean test comparison, an exploratory analysis of the readings was performed in the soil preparation systems, where CO2 was graphically translated into a box-plot diagram. The variables evaluated were: CO2 obtained by means of a infrared gas analyzer; density (Bd), total pore volume (TPV), macroporosity (Ma), microporosity (Mi), resistance to soil penetration (RSP) and chemical attribute: total organic carbon (TOC). The CO2 soil flux presented a significant difference between NT and CT; where respectively the mean values found for SPD, CM, Mata and PC were 2.30; 2.25; 2.18; and 1.39 μmolCO2m-2s-1; the COT had its highest value in the Mata area (32.95 gkg-1), differing statistically from the other areas. It was observed a lower CO2 emission of the soil in the PC, because the system has low input of organic carbon.Keywords: no-tillage; conventional tillage; minimum tillage; total organic carbon.

Heritability Estimates

The objective of this study was to conduct a meta-analysis and test its efficiency in summarizing the heterogeneous data of heritability estimates for the traits of grain yield (GY) and popping expansion (PE), and to provide reliable estimates of selection gains in popcorn. Therefore, 97 heritability estimates ( ) for popcorn GY and PE in the broad and narrow sense were used. The main procedures underlying the estimation of the combined heritability ( ) using the technique of meta-analysis consisted of i) an exploratory analysis of the set of heritability estimates to detect outliers using a box-plot chart, ii) the verification of the required statistical assumptions, iii) testing the involved heritability estimates for homogeneity, and iv) the calculation of the estimates of combined heritability. The meta-analysis facilitated the synthesis of the information pertaining to heritability in popcorn. The combined heritability estimates ( ) in the broad sense for GY and PE were 0.5208 ± 0.0229 and 0.6356 ± 0.0209, respectively, and in the narrow sense were 0.3290 ± 0.0292 and 0.3083 ± 0.0298, respectively.

O estudo da susceptibilidade a erosão laminar é pertinente na mesorregião da Zona da Mata de Minas Gerais, visto a predominância da cobertura de pastagem e pela expressiva degradação do solo. Neste estudo, objetivou-se compreender quais variáveis geodinâmicas são importantes na predição dos processos erosivos laminares e o melhor modelo preditivo entre oito, através de comparações multicritérios, possibilitando entender o fenômeno em uma bacia hidrográfica da mesorregião. Assim, utilizou-se o método de atribuição de notas pela Literatura (L) e Realidade de campo (RC), cuja ponderação de parcela dos processos erosivos (60%) laminares mapeados ponderou a nota das classes das variáveis pela área das mesmas. A integração das variáveis foi por testes de ponderação e integração total e parcial. A avaliação dos modelos gerados foi por estatística descritiva (Box-Plot), diferentes métodos de categorização (Manual, Natural Breaks e Geometrical Interval) e curva ROC com cálculo de eficiência AUC (40% das erosões mapeadas). Os resultados apontaram que a falta umidade é um fator importante para a ocorrência dos processos erosivos laminares, por outro lado, as variáveis morfométricas não foram importantes para a predição. Modelos baseados na RC (72,41% AUC médio) obteve eficiência consideravelmente maior do que a L (65,41% AUC médio), já quando comparado a integração de todas as variáveis geodinâmicas e somente as mais importantes e quando integrado com ponderação e sem ponderação, não houve considerável diferença estatística. O modelo mais eficiente obteve 76,3% AUC, considerado boa e estava adequado a realidade da área estudada.   Study of Susceptibility to Sheet Erosion in a Watershed in Zona da Mata, Minas Gerais, BrazilABSTRACTThe study of susceptibility to surface erosion is relevant in the mesoregion of the Zona da Mata of Minas Gerais, given the predominance of pasture cover, the significant degradation of the soil and the stagnation of the agricultural sector. In this study, the objective was to understand which geodynamic variables are important in the prediction of surface erosive processes and the best predictive model among eight, through multicriteria comparisons, making it possible to understand the phenomenon in a watershed in the mesoregion. Thus, it was used the method of attributing grades by Literature (L) and Field Reality (RC), whose weighting of the mapped surface erosive (60%) processes weighted the grade of the variable classes by their area. The integration of the variables was through weighting tests and total and partial integration. The evaluation of the models generated was by descriptive statistics (Box-Plot), different methods of categorization (Manual, Natural Breaks and Geometrical Interval) and ROC curve with AUC efficiency calculation (40% of the mapped erosions). The results showed that the lack of moisture is an important factor for the occurrence of surface erosive processes, on the other hand, the morphometric variables were not important for the prediction. Models based on RC (72.41% average AUC) achieved considerably greater efficiency than L (65.41% average AUC), when compared to the integration of all geodynamic variables and only the most important ones and when integrated with weighting and without weighting, there was no considerable statistical difference. The most efficient model obtained 76.3% AUC, considered good and was adequate to the reality of the studied area.Key words: Geotechnologies; Comparison of Risk Models; Multicriteria Analysis

The understanding of the sedimentary dynamics is important in the characterization of impacts caused by dredging and this knowledge becomes decisive for their discernment. The aim of this article was to analyze the plume of dispersion of the sediments of the Port of Maceió. The analyzes were carried out in three sampling campaigns, before, during and after the port works, in which the collection points in the dredging and discard areas were plotted. The suspended particulate material (SPM) was analyzed using the gravimetric method and in situ sampling of the parameters turbidity, dissolved oxygen and percentage of saturation, salinity and electrical conductivity with a multiparameter probe and water transparency with Secchi disk. The parameters SPM, turbidity and transparency were analyzed by linear interpolation, while the other variables were subjected to analysis on a polynomial calibration curve. The multiparameters worked were submitted to box plot analysis in order to assess the variance between campaigns. The variation of SPM in the sample campaigns showed dynamic spatial and temporal behavior; The interpolation promoted a better visualization of the physical parameters that directly express the plume of dispersion; The supplementary variables showed trend patterns in relation to the sediment charge; Box plot analysis proved to be pertinently useful for evaluating and interpreting the results in an integrated manner, mainly due to the large number of parameters analyzed; The dredging works had a balanced management between the amount of dredged sediments and their spatial disposition at the discard site when compared to the dredging area.

ABSTRACT: Santo Giorno cheese, obtained from raw milk and selected autochthonous starters, is emerging as the newest typical food product from the Southwestern region of Paraná, Brazil. The objective of this study was to evaluate the acceptance of the cheese with two ripening times of 60 and 180 days, produced in two dairy factories, testing two starters and two preservatives. Subjective sensory evaluation was applied using 129 consumers and hedonic scales for the attributes and for purchasing intent. A questionnaire involving the rate of cheese consumption was also used. The results suggested good reproducibility of the cheese preparation by the dairy factories, with no significant differences between the type of preservative used and the suitability of the two types of starter tested. An inverse relationship between hedonic scores for attributes (appearance, color, odor, texture, flavor) and ripening time was observed, except for texture. By applying multinomial logistic regression and a box plot analysis, a significant effect of age on cheese purchasing intent was verified, with a mean acceptance rate of 87.8% for 60 days ageing and 81.8% for 180 days ageing. Results revealed a possible Santo Giorno cheese public of older consumers who had a cheese consuming habit.
