| Time periods of walking-grazing, standing and lyingof cattle’s life can be used to predict their health. However, famer cannot observe those in all the time. Therefore, this paper proposes a simple technique to classify the cattle behaviors by using the magnitude and the variance of accelerometer output signal. There are two steps of algorithm detection, the first step employed the magnitude of each axis for classifying the cattle behaviors into two groups: 1) walking-grazing and standing and 2) lying. After that, the second step used the variance of Y-axis to notify between walking-grazing and standing behaviors. The classification results were inform time periods of each behavior and tested with two cattle. The measured precise times of each behavior... |

| Variance and performance of two sampling plans for aflatoxins quantification in maize were evaluated. Eight lots of maize were sampled using two plans: manual, using sampling spear for kernels; and automatic, using a continuous flow to collect milled maize. Total variance and sampling, preparation, and analysis variance were determined and compared between plans through multifactor analysis of variance. Four theoretical distribution models were used to compare aflatoxins quantification distributions in eight maize lots. The acceptance and rejection probabilities for a lot under certain aflatoxin concentration were determined using variance and the information on the selected distribution model to build the operational characteristic curves (OC). Sampling... |

| ABSTRACTThe aim of this study was to establish and compare, as to their representativeness, core collections obtained from quantitative data, multicategoric, molecular and collections that covering all this information simultaneously. Ten subcollections were established from 67 tomato accessions of the Germplasm Bank of the Universidade Federal de Viçosa (BGH-UFV), characterized according to 19 quantitative traits, 30 multicategoric characters, 52 ISSR loci and to the reaction to three pathogens. These subcollections were defined by the combination of the nature of data collected and the sampling rate. The COD-20 subcollection stood out in 20% intensity of sampling by has higher rates of coincidence amplitude followed by more appropriate values of... |

| This study presents an application of the geostatistical one-dimensional (1D) transitive method for estimating the precision of acoustic pelagic abundance estimates in Senegal. In applying the method, the major problem encountered was how to take into account the temporal variability in the computation of the estimation variance. In acoustic surveys, echointegration is performed continuously along the ship's sailing track. For a survey design made of parallel transects, each transect can thus be considered as a sampling unit. By summing the density values along the transects to obtain biomass values per transect, the 2D estimation is simply reduced to a 1D estimation procedure. If the transects are equidistant, the geostatistical transitive method applied... |

| O objetivo deste trabalho foi avaliar a resistência do fungo Ceratocystis cacaofunesta, que causa a murcha de ceratocystis, doença letal do cacaueiro. Em março de 2005, na Estação Experimental Joaquim Bahiana do Centro de Pesquisas do Cacau (Cepec), situada no município de Itajuípe, Bahia, Brasil foi instalado no campo um experimento com progênies de 27 cruzamentos dispostos em blocos ao acaso no espaçamento de 3x3 metros com parcelas de 30 plantas e 4 repetições, totalizando 120 plantas/cruzamento. As plantas das progênies dos 27 cruzamentos foram avaliadas em relação à doença, e, em outubro de 2012, os dados da incidência de plantas mortas foram submetidos à análise de variância e da herdabilidade. As médias de incidência da doença variaram de 0,83 a... |

| Breeding cycle in rubber extends to 20-30 years between pollination and yield assessment, distributed over three selection stages. Five hectares of small scale trial of rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell.-Arg.], was established in the Northwestern region of São Paulo State, Brazil. The population comprises 98 clones mostly derived from intensively selected plus tree in the natural forest of rubber tree in the Amazon. Three open pollinated progeny tests were established in three experimental stations. Seedlings from 98 progenies including a commercial check (CC) were planted in each one of the three locations. Assessments were made when the plants were one, two and three years old. The variation among progenies for girth was... |

| As with other areas of science, supply chain analysis suffers from the fact that practitioners of its different component disciplines often find it exchange results and methods of analysis. For fresh produce supply chains a key issue is how to unite the elegant mathematical work on the physiology of quality change with the more qualitative methods of social science that are applied to the analysis supply chain management. This paper explores the possibility of utilising approaches which are widely used in demography to unify concepts of quality modelling and supply chain efficiency in the fresh produce sector. A key feature of demographic (or karpographic) models is that they use the average properties of individuals to model the behaviour of cohorts (or... |

| This work was carried out to evaluate the statistical properties of eight nonlinear models used to predict nitrogen mineralization in soils of the Southern Minas Gerais State, Brazil. The parameter estimations for nonlinear models with and without structure of autoregressive errors was made by the least squares method. First, a structure of second order autoregressive errors, AR(2) was considered for all nonlinear models and then the significance of the autocorrelation parameters was verified. Among the models, the Juma presented an autocorrelation of second order, and the model of Broadbent presented one of first order. In summary, these models presented significant autocorrelation parameters. To estimate the parameters of nonlinear models, the SAS... |

| Since 1982, the New Castle County Superior Court in Delaware has promoted mediation, which attempts to resolve filed conflicts prior to trial. This paper evaluates how spatial land-use conflicts channel through mediation and litigation. Data suggest that mediations fail because one of the key disputing parties does not play a direct role in mediation and litigation. The data then inform a predictive model of litigated outcomes in which disputants share in the responsibility for conflict. By alleviating some of the uncertainty of litigation and proposing win-win, mediated outcomes, the model may be used facilitate future mediations. |
