25. Estudo da qualidade da água por meio de bioindicadores bentônicos em córregos da área rural e urbana
Resumo Na avaliação da qualidade da água, além das análises físico-químicas e geoquímicas, outros métodos podem ser utilizados para realizar estudos ou monitoramentos. O objetivo deste estudo foi utilizar espécies de bioindicadores bentônicos intolerantes, tolerantes e resistentes às alterações na qualidade da água de dois córregos, considera

26. Genetic divergence among cupuaçu accessions by multiscale bootstrap resampling
This study aimed at investigating the genetic divergence of eighteen accessions of cupuaçu trees based on fruit morphometric traits and comparing usual methods of cluster analysis with the proposed multiscale bootstrap resampling methodology. The data were obtained from an experiment conducted in Tomé-Açu city (PA, Brazil), arranged in a completely random

27. Using AFLP-RGA markers to assess genetic diversity among pigeon pea (Cajanus cajan) genotypes in relation to major diseases
Resistance gene analog (RGA)-anchored amplified fragment length polymorphism (AFLP-RGA) marker system was used in order to evaluate genetic relationships among 22 pigeon pea genotypes with varied responses to Fusarium wilt and sterility mosaic disease. Five AFLP-RGA primer combinations (E-CAG/wlrk-S, M-GTG/wlrk-S, M-GTG/wlrk-AS, E-CAT/S1-INV and E-CAG/wlrk-A

28. Morphological phenotypic dispersion of garlic cultivars by cluster analysis and multidimensional scaling
Multivariate techniques have become a useful tool for studying the phenotypic diversity of Germplasm Bank accessions, since they make it possible to combine a variety of different information from these accessions. This study aimed to characterize the phenotypic dispersion of garlic (Allium sativum L.) using two multivariate techniques with different objecti

29. Bryophytes on rocky outcrops in the caatinga biome: a conservationist perspective
In the state of Paraíba, Brazil, there is an abundance of rocky outcrops, which are typical elements of the semi-arid landscape. Those outcrops provide refuge to species with morphological adaptations to stressful climates and to rare communities of plants, including bryophytes. Nevertheless, there have been no studies of bryophytes in such habitats in the

30. Caracterização molecular de cultivares de melancia usando marcadores microssatélites
Foram estabelecidos padrões alélicos e distâncias genéticas para 17 cultivares de melancia utilizando marcadores microssatélites. Para a visualização da similaridade genética, utilizou-se o dendrograma UPGMA (Unweighted Pair Group Method with Arithmetic Mean) gerado da matriz de distâncias do coeficiente de Jaccard, com base em 34 alelos de dez loco

31. Cluster evaluation of Brazilian and Moroccan goat populations using physical measurements
The aim of this study was to compare the genetic diversity of 12 populations of goats in Brazil and Morocco (n = 796) through the use of physical measurements and different multivariate techniques. Traits measured included wither height (WH), distance from the brisket to the ground (BH) and ear length (EL). The standardized Euclidean distance (D) was adopted

32. Taxa de geração de resíduos da construção civil em edificações na cidade de João Pessoa / GENERATION RATE OF CONSTRUCTION WASTE IN BUILDINGS IN THE CITY OF JOÃO PESSOA.
Given the high index of construction in the city of João Pessoa, in northeast Brazil and the frequent irregular disposal of its residues, the objective of this work was to study the generation rate of construction wastes (CW) based on constructed area of the building, so that a more effective inspection can be implemented by the proper instances. A sample o

33. Genetic diversity of Leishmania infantum field populations from Brazil
Leishmania infantum (syn. Leishmania chagasi) is the etiological agent of visceral leishmaniasis (VL) in Brazil. The epidemiology of VL is poorly understood. Therefore, a more detailed molecular characterization at an intraspecific level is certainly needed. Herein, three independent molecular methods, multilocus microsatellite typing (MLMT), random amplific

34. cDNA-AFLP analysis of Psidium guajava L. cultivars under water stress and mechanical injury: methodological implications
Studies involving amplified fragment length polymorphism (cDNA-AFLP) have often used polyacrylamide gels with radiolabeled primers in order to establish best primer combinations, to analyze, and to recover transcript-derived fragments. Use of automatic sequencer to establish best primer combinations is convenient, because it saves time, reduces costs and ris

35. Avaliação e mensuração da dor no envelhecimento: instituições de longa permanência / Assessment and measurement of pain in aging: long-term institutions
Aging is a new phenomenon and a global trend. With it, there is an increase of diseases and complaints of pain. This study has allowed health professionals have a better assessment of pain perception in aging. The overall objective was to evaluate the different types of chronic pain in aging. The specific objectives were to measure the perceived pain, to eva

36. Lipidograma e glicemia de búfalos leiteiros criados no Estado de São Paulo: influência de fatores fisiológicos e valores de referência / Lipid and glucose profile of dairy buffaloes raised in São Paulo state: influence of physiological factors and reference values
The aim of this study was to analyze the influence of age, gender, pregnancy, puerperium, lactation and breeding systems in the constituents of lipid metabolism and glucose of buffaloes. The biochemical analysis was obtained by determining the levels of serum cholesterol, triglycerides, beta-hydroxybutyrate (ß-HBO), non-esterified fatty acids (NEFA) and pla
