1. Population structure, diametric distribution and use of Commiphora leptopholoeos (Mart.) JB Gillett in arboreal Caatinga
ABSTRACT The objective of this work was to characterize the population structure, analyze the spatial distribution pattern and identify the potential use of the Commiphora leptopholoeos in the Contendas do Sincorá National Forest, BA. Thus, three disjoint transects of 40 x 160 m were installed for the phytosociological study and spatial distribution and sub

2. Lower pole anatomy of horseshoe kidney and complete ureteral duplication: Anatomic and radiologic study applied to endourology
ABSTRACT Purpose: To analyze the 3-dimensional intrarenal anatomy of horseshoe kidneys (HK) and kidney with complete ureteral duplication (CUD), in polyester resin endocasts of the collecting system and in patients submitted to 3D computerized tomography scan (CT-scan). Materials and Methods: We analyzed seven 3-dimensional polyester resin endocasts of the

3. A SIR Model with Spatially Distributed Multiple Populations Interactions for Disease Dissemination
ABSTRACT In this contribution we analyze a discretized SIR (Susceptible, Infectious, and Removed) compartmental model, to investigate the role of individual interactions in the spread of diseases. The compartments S i,j , I i , j and R i , j ( i , j , = 1 , 2 , . . . , n ) are spatially distributed in a two-dimensional n × n network. We assume tha

4. Spatial Distribution of Droughts in the Titicaca Lake Basin
Resumo A presente pesquisa avaliou a distribuição espacial do risco de seca na bacia hidrográfica do lago Titicaca localizada em território peruano para uma escala de distrito, com base em perigo e vulnerabilidade. O perigo foi quantificado com o déficit de precipitação usando índice de Precipitação Padronizado (SPI, por suas siglas em inglês), pa

6. Bioclimatic zoning for quails in the dry period in the state of Paraíba, Brazil
ABSTRACT Based on the temperature and humidity index, for quails from the 3rd to the 5th week of life, in the dry period in Paraíba state, Brazil, the objective was to carry out a bioclimatic zoning, identifying as regions suitable for the reproduction of quails and, when necessary, mitigating measures for greater animal comfort. The bioclimatic zoning was

8. On the classification and treatment of outliers in a spatial context: A Bayesian Updating approach
Abstract Checking and treating extreme values is commonplace in modelling workflows. The main methods to manage outliers may be categorized into graphical, Kriging- and simulation-based approaches. While graphical methods usually classify outliers from a global perspective, geostatistical methods evaluate outliers in a local context. Ordinary-Kriging based a

9. Two-dimensional spatial distribution modeling of sprinkler irrigation
ABSTRACT Irrigation can provide significant agronomic and financial returns on agricultural activity. The maximization of the benefits obtained from irrigation depends, among other factors, on the water use efficiency, which is intrinsically related to application uniformity. For the sprinkler method, the irrigation uniformity assessment is based on results

10. SPATIAL AUTOCORRELATION OF PHYSICAL ATTRIBUTES OF AN OXISOL
ABSTRACT Studies that seek to identify a smaller number of soil attributes that represent others can generate less expenditure of time and financial resources for monitoring cultivated areas. Thus, this study aimed to analyze the spatial distribution and spatial autocorrelation of physical attributes of an Oxisol (Latossolo Vermelho Amarelo, Brazilian Soil C

11. Limnological layers improve species distribution modeling of aquatic macrophytes at fine-spatial resolution
ABSTRACT Species distribution modeling (SDM) studies of aquatic macrophytes are still attached to methodological paradigms focused on terrestrial plants, such as the use of bioclimatic layers. Our goal was to evaluate the applicability of this paradigm based on a SDM study of Egeria densa, Pontederia crassipes, and Salvinia auriculata in the São Francisco r

12. Spatial Distribution and Pollution Assessment of Trace Elements Pb, Cu, Ni, Fe and As in the Surficial Water of Staring Bay, Indonesia
Staring Bay has long been used by the local community for fisheries and fishing activities; however, the rapid population growth and industrial activities around the bay in recent years are predicted to contribute significantly to the increase of waste entering the bay. This particular study was aimed to provide baseline levels of trace elements Pb, Cu, Ni,
