1. Dynamic anisotropy and non-linear geostatistics supporting short term modelling of structurally complex gold mineralization
Abstract Non-linear geostatistical methods are known to deal appropriately with the geological and geometrical complexity of gold deposits. This article reports the results related to an investigation to improve the gold content estimate based on restricted ore modeling to honor the structural aspects that control the mineralization. The grade domains are de

2. Geostatistical simulations with heterotopic hard and soft data without modeling the linear model of coregionalization
Abstract Most mining decisions are based on models estimated/simulated given the information obtained from samples. During the exploration stage, samples are commonly taken using diamond drill holes which are accurate and precise. These samples are considered hard data. In the production stage, new samples are added. These last are cheaper and more abundant

3. What are the drivers of popularity and versatility of medicinal plants in local medical systems?
ABSTRACT The cultural importance of medicinal plants has been measured in terms of popularity (number of people who know a plant) and versatility (number of therapeutic indications mentioned for a plant). Previous works have provided evidence about some drivers of medicinal plant importance, such as attributes of availability, efficiency, palatability and ta

4. Scaling Symmetries and Conservation Laws for Variable-coefficients Nonlinear Dispersive Equations
RESUMO. Simetrias de escala surgem em diferentes ramos da física e abordagens baseadas em simetria são poderosas ferramentas para estudar modelos invariantes por escala, pois podem fornecer leis de conservação que não são óbvias por inspeção. Nessa perspectiva, a classe de equações dispersivas não-lineares com coeficientes variáveis vc K ( m ,

6. Correção de medida ultrassonográfica de carcaça em coelhos usando modelo linear misto com covariáveis
RESUMO Objetivou-se avaliar a correção da medida ultrassonográfica da área do músculo Longissimus dorsi, em coelhos da raça Nova Zelândia, pela análise de covariância usando modelos mistos. Foram realizadas análises em delineamento em blocos completos ao acaso, com cinco tratamentos (operadores) e seis blocos (animais), considerando na análise: a

7. Allometric models to estimate tree height in northern Amazonian ecotone forests
RESUMO Modelos alométricos que definem o relacionamento entre diâmetro do tronco e a altura total da árvore na bacia amazônica são importantes porque refinam as estimativas de fluxo e estoques de carbono arbóreo na região. Este estudo testou diferentes modelos alométricos para estimar a altura total de árvores a partir do diâmetro do tronco em uma

8. Composition and ecology of a snake assemblage in an upland forest from Central Amazonia
Abstract: Most species of Amazonian snakes have wide geographic distributions. However, local environmental factors influence the formation of assemblages in different localities. In this study, we investigated the composition of the assemblage and the effect of environmental variables on the distribution of the species inhabiting an upland forest in the Exp

9. Slash Spatial Linear Modeling: Soybean Yield Variability as a Function of Soil Chemical Properties
ABSTRACT: In geostatistical modeling of soil chemical properties, one or more influential observations in a dataset may impair the construction of interpolation maps and their accuracy. An alternative to avoid the problem would be to use most robust models, based on distributions that have heavier tails. Therefore, this study proposes a spatial linear model

10. ORDEN, DISTRIBUTIVIDAD Y ATRACCIÓN EN LA PRODUCCIÓN DE LA CONCORDANCIA
ABSTRACT: Several studies have found that factors of different nature (semantic, morphological and syntactic) affect the computation of subject-verb agreement during sentence production (BOCK; MILLER, 1991; FRANCK; VIGLIOCCO; NICOL, 2002; HARTSUIKER et. al., 2003; HASKELL; MACDONALD, 2003; VIGLIOCCO; BUTTERWORTH; SEMENZA 1995) The aim of this paper are: a) t

11. The eco-epidemiology of Triatoma infestans in the temperate Monte Desert ecoregion of mid-western Argentina
BACKGROUND The eco-epidemiological status of Chagas disease in the Monte Desert ecoregion of western Argentina is largely unknown. We investigated the environmental and socio-demographic determinants of house infestation with Triatoma infestans, bug abundance, vector infection with Trypanosoma cruzi and host-feeding sources in a well-defined rural area of

12. Analog Models of Flanking Structures and a Natural Example in the Quadrilátero Ferrífero, Minas Gerais
ABSTRACT The aim of this study is to present analog models of flanking structures and to analyze the Fábrica Nova synform, Quadrilátero Ferrífero, Minas Gerais, from a geometric point of view. We set up seven models using a linear viscous silicone and produced flanking structures with a shear velocity of 2 cm h-1. At different initial orientations with re
