1. PHYSICAL ANALYSIS OF REGIONALIZED FLOW AS AN AID IN THE IDENTIFICATION OF HYDROLOGICALLY HOMOGENEOUS REGIONS
ABSTRACT Regionalization is an important technique for estimating the flow of hydrographic sections with a lack of data. First, it is necessary to identify hydrologically homogeneous regions (HHRs), which are commonly validated via statistical analyses. Because this step is understood to be subjective, studies that contribute to a greater reliability in iden

2. Variation in root morphology of epiphytic orchids along small-scale and large-scale moisture gradients
ABSTRACT Root morphology is expected to respond to environmental conditions. Two earlier studies reported predictable changes in the structure of the velamen radicum (common in monocotyledons) along rainfall gradients, which was expected from its assumed role in plant-water-relations. The present study expanded on this idea by analysing nine root traits that

3. NUGGET EFFECT INFLUENCE ON SPATIAL VARIABILITY OF AGRICULTURAL DATA
ABSTRACT Spatial variability description of soil chemical properties by thematic maps depends substantially on suitable geostatistical models. One of the parameters composing a geostatistical model is nugget effect. This study aimed to evaluate the simultaneous influence of nugget effect and sampling design on geostatistical model estimation and estimation o

4. Seasonal and longitudinal variation in fish assemblage structure along an unregulated stretch of the Middle Uruguay River
RESUMO Os padrões de diversidade e suas causas continuam sendo questões importantes, especialmente em ecossistemas que preservam condições naturais. Este é o caso da diversidade de peixes em grandes rios neotropicais. Neste contexto, investigamos padrões de diversidade de peixes ao longo de um extenso gradiente fluvial (ca. 450 km) no médio rio Urugua

6. Spatial Dependence of Udder Surface Temperature Variation in Dairy Cows with Healthy Status and Mastitis
RESUMO Objetivou-se com essa pesquisa avaliar o padrão de variabilidade espacial da temperatura de superfície do úbere de vacas leiteiras saudáveis e com mastite. Foram selecionados 24 animais, oito saudáveis, oito com mastite subclínica e oito com mastite clínica. As imagens foram obtidas a partir de uma câmera termográfica Flir i60, resolução de

7. Determinants and spatial dependence of innovation in Brazilian regions: evidence from a Spatial Tobit Model
Resumo Este artigo busca analisar os determinantes da inovação, os padrões espaciais e a dependência espacial da inovação nas microrregiões brasileiras. Em concreto, ele avalia como o P&D das empresas locais, a pesquisa acadêmica regional, o nível de aglomeração e a especialização ou diversificação industrial da localidade afetam a inovação

8. Incidence and spatial distribution of Chronic Myeloid Leukemia by regions of economic development in the state of Pernambuco, Brazil
ABSTRACT Background: The establishment of regional development poles in the State of Pernambuco, Brazil was characterized by industrial expansion and consequent concerns about the increase in the occurrence of diseases, specifically those having long latency periods, as is the case of Chronic Myeloid Leukemia. Methods: The study included 367 patients diagn

9. Análise da influência da malha de pontos em índices de avaliação de desempenho da luz natural
Resumo O desempenho da iluminação natural de ambientes pode ser avaliado por meio de várias ferramentas, a maioria baseada na iluminância. Mesmo com os avanços nas últimas décadas, principalmente os computacionais, a definição dos pontos da malha é deixada, em geral, para escolha do simulador. Este artigo tem como objetivo analisar a influência da

11. SPATIAL VARIABILITY MAPPING OF SUGARCANE QUALITATIVE ATTRIBUTES
ABSTRACT Spatial variability evaluation of qualitative attributes can be used as an excellent strategy to design forms of intervention that result in better crop profitability for some agricultural crops, for example, sugarcane. Based on the assumption that qualitative attributes of sugarcane present spatial variability and their distributions along the stem

12. SENSOR SYSTEMS FOR MAPPING SOIL FERTILITY ATTRIBUTES: CHALLENGES, ADVANCES, AND PERSPECTIVES IN BRAZILIAN TROPICAL SOILS
ABSTRACT Soil fertility attributes have different scales and forms of spatial and temporal variations in agricultural fields. Adequate spatiotemporal characterization of these attributes is fundamental to the successful development of strategies for variable rate application of fertilizers, enabling the classic benefits of precision agriculture (PA).
