13. Distribuição espacial de formigueiros de Acromyrmex crassispinus (Forel)(Hymenoptera: Formicidae) em plantios de Pinus taeda
The spatial distribution of insects is essential to perform control strategies, to improve sample techniques and to estimate economic losses. We aimed to determine the spatial distribution of nests of Acromyrmex crassispinus (Forel) in Pinus taeda plantations. The experiments were carried out in P. taeda plantations with different ages (treatments: recently-

14. Distribuição espacial de Tenuipalpus heveae Baker (Acari: Tenuipalpidae) na cultura da seringueira
The objective of this work was to study the spatial distribution of Tenuipalpus heveae Baker in rubber tree plantations. The experimental area was located in Marinópolis, State of São Paulo, and corresponded to a total of 1,000 plants (clone RRIM 600) divided in 100 plots of ten plants each. A total of 16 samplings were conducted, approximately once every

15. The burrows of Parastacus defossus (Decapoda: Parastacidae), a fossorial freshwater crayfish from southern Brazil
Parastacus defossus Faxon, 1898 is a fossorial crayfish species, which constructs its burrows in swampy areas in southeast Uruguay and in the state of Rio Grande do Sul, Brazil. The present field study was carried out in Lami, Porto Alegre, Rio Grande do Sul, Brazil, from May 2003 through August 2005. Environmental measurements (temperature, pH, dissolved ox

16. Clustering of psychiatric and somatic illnesses in the general population: multimorbidity and socioeconomic correlates
The distribution of psychiatric disorders and of chronic medical illnesses was studied in a population-based sample to determine whether these conditions co-occur in the same individual. A representative sample (N = 1464) of adults living in households was assessed by the Composite International Diagnostic Interview, version 1.1, as part of the São Paulo Ep

17. Spatial distribution of parasitism on Phyllocnistis citrella Stainton, 1856 (Lepidoptera: Gracillariidae) in citrus orchards
Many species of microhymenopterous parasitoids have been registered on Phyllocnistis citrella, the citrus leafminer. The present study aimed to identify the spatial distribution pattern of the native and introduced parasitoids of P. citrella in two citrus orchards in Montenegro, RS. The new shoots from 24 randomly selected trees in each orchard were inspecte

18. Desenvolvimento de métodos de detecção precoce de infecções quiescentes de Colletotrichum spp. em mamão / Development of early detections methods of quiescent infections of Colletotrichum spp. on papaya fruits
The objetives of this study were to evaluate the methods, maturation age, temperature effect, distribution and sample size to detect quiescent infection of Colletotrichum spp. (Glomerella cingulata) on papaya fruits. At first, different methods to detect quiescent infections on immature fruits were assessed: sodium hipoclorite (1,5%), paraquat (6 ml/L a.i.),

19. Inferência bayesiana objetiva e freqüentista para a probabilidade de sucesso
Neste estudo são abordadas duas distribuições discretas baseadas em ensaios de Bernoulli, a Binomial e a Binomial Negativa. São explorados intervalos de credibilidade e confiança para estimação da probabilidade de sucesso de ambas as distribuições. A principal finalidade é analisar nos contextos clássico e bayesiano o desempenho da probabilidade d

20. ANÁLISE ESPACIAL DA MORTALIDADE POR DOENÇAS DO APARELHO CIRCULATÓRIO NAS REGIÕES URBANAS DE JUIZ DE FORA - MG
The cardiovascular diseases (CVD) are the main causes of death in Juiz de Fora, in Brazil and in most countries. The spatial distribution of CVD mortality in large cities is not homogeneous: regions with worse social conditions have bigger mortality rates. Premature CVD mortality is also related to socioeconomic conditions of neighborhood. The techniques of

22. Distribuição Espacial de Insetos em Algodoeiro Bt e não-Bt / Spatial Distribution of Alabama argillacea (Hübner) and Heliothis virescens (Fabricius) (Lepidoptera, Noctuidae) Eggs on Bt and Non-Bt Cotton
Among the several options for controlling Alabama argillacea (Hübner) and Heliothis virescens (Fabricius) larvae on the cotton crop, as insecticides spraying and biological control, the transgenic Bt-cotton has been inserted as an extremely viable alternative, however it is not known with accuracy as the transgenic plants affect the populations of organisms

23. Distribuições em série de potências modificadas : abordagem clássica e bayesiana
We present some mathematical properties of the class of modified power series distributions (MPSD) introduced by Gupta (1974). This class of distribution includes some important distributions such as the binomial, negative binomial, Poisson, logarithmic series, among others. More recently, this class of models was studied in the context of regression models
