1. THE EXPLORATORY DIMENSION OF FMRI EXPERIMENTS
Abstract Driven by an appreciation of the field’s early stage of development, I apply the concept of exploratory experimentation, originally put forward in the late 90s philosophy of biology, to current research in cognitive neuroscience. I concentrate on functional magnetic resonance imaging and how this wide-spread technique is used, from experimental de

4. Biology and fertility life table of Bactrocera carambolae on grape and acerola
ABSTRACT Bactrocera carambolae Drew & Hancock (Diptera: Tephritidae), native of Southeast Asia, is present in Brazil but restricted to Amapá, Pará and Roraima, where it has quarantine pest status. The possible dispersion to other fruit producing regions of Brazil could cause damages, including for exportation, due to quarantine restrictions imposed by frui

5. Buttonweed emergence as affected by seed burial depth and straw on the soil surface
Knowledge of the effects of seed burial depth and the presence of straw on the soil surface on weed seedling emergence provides useful information for the development of weed management tactics. Buttonweed (Borreria densiflora DC.) is a troublesome weed that occurs in large infestations in soybean and sugarcane crops from north-central Brazil. This study inv

6. Biology and reproductive capacity of Spodoptera eridania (Cramer) (Lepidoptera, Noctuidae) in different soybean cultivars
This study aimed to evaluate the development, survival and reproductive capacity of Spodoptera eridania in four soybean cultivars. The experiment was conducted in the laboratory, in a climatic chamber at 25 °C ± 1 °C, 70 ± 10% relative humidity and 12 h photophase. The cultivars used were: FMT Tabarana, BRS/MT Pintado, FMT Tucunaré and Monsoy 8757, all

7. Efeitos do inseticida endossulfam sobre a morfologia e a morfometria testicular em morcegos frugívoros Artibeus lituratus (OLFERS, 1818) / Effects of the endosulfan on the testicular morphology and morphometry in fruit bats Artibeus lituratus (OLFERS, 1818)
Large amounts of agricultural chemicals are discharged into the environment in Brazil. These pesticides are often used to destroy or impair the activity of organisms that attack crops. There are some reports in the literature concerning the decline of many wildlife populations as a result of contamination of their habitats by pesticides. One of the putative

8. PARÂMETROS IMUNOLÓGICOS FRENTE À CONTAMINAÇÃO POR SALMONELLA ENTERITIDIS EM AVES TRATADAS E NÃO TRATADAS COM ÁCIDOS ORGÂNICOS E SUA DETECÇÃO POR MÉTODOS FENOTÍPICOS E GENOTÍPICOS / IMMUNOLOGICAL PARAMETERS IN THE CONTAMINATION BY SALMONELLA ENTERITIDIS IN POULTRY TREATED AND NOT TREATED WITH ORGANIC ACIDS AND THEIR DETECTION BY PHENOTYPIC AND GENOTYPIC METHODS
Salmonellosis is a public health problem that involves issues in animal health and food handling practices that require combined actions to minimize its effects. This disease is a zoonosis with the greatest impact on public health throughout the world due to: high endemicity, high mortality and especially by its difficult to control and the development of an

9. Interação trófica entre Podisus nigrispinus e Supputius cincticeps (Heteroptera: Pentatomidae) / Trophic interaction between Podisus nigrispinus and Supputius cincticeps (Heteroptera: Pentatomidae)
Prey may be more or less consumed by control biologic agents and presents three kinds of interspecific interactions, (1) synergism, increase of mortality of prey comparing to each natural enemy independently, when the foraging of one species facilitates the capture of pest by another natural enemies. (2) Total mortality of the pest to natural enemies equals

10. A pipeline to study structural interactions among Spodoptera frugiperda serine proteinases and plant proteinase inhibitors.
We propose here a computational biology pipeline to identify and analyze possible structural determinants that could explain some level of insensitivity by S. frugiperda serine proteinases (SPs) against plant PIs observed in a real time PCR experiment.

12. WOntoVLab: um processo para autoria de laboratórios virtuais baseado em workflows e ontologias
Virtual laboratories can be used by educational institutions to facilitate and enrich the learning of specific procedures, however they can be also used by industry in demonstrations, tests and trainings. Laboratorial practices are normally performed in physical laboratories, but sometimes it is necessary to afford a great amount of money to acquire apparatu
