25. Population dynamics of Megalobulimus paranaguensis (Gastropoda: Pulmonata) in the southeast coast of Brazil
ABSTRACT. The population dynamics of Megalobulimus paranaguensis (Pilsbry & Ihering, 1900), a large and long-lived land gastropod from Brazil's Southeast (Atlantic Forest) was studied between 2006 and 2009, at an urban park in the city of Santos, state of São Paulo. The study included biometry, weighing, and marking and recapture of adult individuals. The v

26. Proposing the novelty classifier for face recognition
INTRODUCTION: Face recognition, one of the most explored themes in biometry, is used in a wide range of applications: access control, forensic detection, surveillance and monitoring systems, and robotic and human machine interactions. In this paper, a new classifier is proposed for face recognition: the novelty classifier. METHODS: The performance of a novel

27. Efeitos do trimetilaminoetano (TES) e ringer lactato em sêmen de macacos-aranha mantidos em cativeiro ( Ateles paniscus e A. marginatus)
The performances of the diluents TES and CEBRAN II were compared as cryopreservatives of semen from non human primates of the genus Ateles. The experiment was carried out using one Ateles marginatus and two Ateles paniscus specimens, males and adults, maintained in the same captivity conditions at the National Center of Primates (CENP-SVS/MS). The animals we

28. Fruit biometry and seed germination of Syagrus romanzoffiana (Cham.) Glassm
Syagrus romanzoffiana (Cham.) Glassm. is a species native to Brazil that is of ecological and aesthetic importance. This study aims to describe the biometric characteristics of S. romanzoffiana fruits and to assess the effects that treatments meant to overcome dormancy and partial drying have on seed germination. For biometric characterization, each repetiti

29. Produção e desenvolvimento da nogueira macadâmia em clima Cwa / Macadamia production and development at the Cwa climate
The macadamia cultivation presents itself as an important alternative for fruit growers of the State of São Paulo, mainly because of its rusticity and the value reached by their fruits. However, studies related to their development and characteristics of production are essential for the correct choice of the variety to be cultivated. In order to characteriz

30. Avaliação da toxicidade em água e sedimento do rio Cubatão-SP / Assessment of toxicity in water and sediment from Cubatão River - SP
O monitoramento de corpos hídricos receptores de efluentes pode ajudar na manutenção e conservação desses locais, pois os poluentes podem alterar o equilíbrio, a estrutura e o funcionamento do ecossistema. Neste aspecto, o estudo em sedimentos é importante ao permitir uma avaliação mais abrangente do ecossistema aquático, onde diferentes contaminan

31. Adoption : realities and challenges for the twenty-first century Brasil / Adoção : realidade e desafios para um Brasil do século XXI
O conceito de adoção varia de acordo com a época e com as tradições. E o tema, além de invadir a discussão de ordem moral, atinge diversas áreas do conhecimento, entre elas a Demografia. Com a evolução da legislação brasileira sobre adoção, principalmente no final do século XX, nota-se que a prioridade é a qualidade de vida da criança ou ado

33. Biometric and statistical investigations on the cnidoma of the genus Hydra (Cnidaria, Hydrozoa)
This paper deals about the nematocysts like a source of biometric information for comparison between the species Hydra vulgaris Pallas, 1766, Hydra vulgaris pedunculata Deserti et al., 2011 and Hydra pseudoligactis (Hyman, 1931). This biometric tool lets us carry out statistical comparisons and adding these results to the identification of specimens from dif

34. Morphometrical development of tambaqui (Colossoma macropomum, Cuvier, 1818) under different photoperiods
The experiment was performed with 160 tambaqui (Colossoma macropomum) with average weight 11.01±2.08 g and total length 7.8±0.18 cm. Fishes were kept in sixteen aquariums with 56 L of water at 29.1±0.4 ºC of temperature, initial stocking density 1.97 g/L and constant aeration. The objective of this study was to assess the influence of photoperiod on fish

35. Effectiveness of estradiol valerate on sex reversion in Astyanax altiparanae (Characiformes, Characidae)
The objective of this study was to evaluate the effectiveness of estradiol valerate in an attempt to feminize the male Astyanax altiparanae. One thousand newly-hatched larvae were randomly distributed in four incubators. During a period of 30 days, estradiol valerate was administered in different dosages (20, 40, and 80 mg/kg of diet); the control group did

36. Testicular morphology of adult wistar rats treated with Rudgea viburnoides (Cham.) Benth. leaf infusion
The present study was carried out to investigate the effects of Rudgea viburnoides infusion on the body biometry and testicular morphometry and stereology of adult Wistar rats. Two groups received the infusion daily at the concentration of 3 or 6 mg/mL for 40 days. The control group received only water. Neither the biometrical parameters nor the tubular diam
