1. Environmental enrichment restores cognitive deficits induced by experimental childhood meningitis
Objective: To evaluate the influence of environmental enrichment (EE) on memory, cytokines, and brain-derived neurotrophic factor (BDNF) in the brain of adult rats subjected to experimental pneumococcal meningitis during infancy. Methods: On postnatal day 11, the animals received either artificial cerebrospinal fluid (CSF) or Streptococcus pneumoniae suspen

2. DETECTION OF MASSES IN MAMMOGRAPHY IMAGES USING CELLULAR NEURAL NETWORKS, STATISCAL FUNCTIONS VECTOR MACHINES AND SUPPORT / DETECÇÃO DE MASSAS EM IMAGENS MAMOGRÁFICAS USANDO REDES NEURAIS CELULARES, FUNÇÕES GEOESTATÍSTICAS E MÁQUINAS DE VETORES DE SUPORTE
Breast cancer presents high occurrence frequency among the world population and its psychological effects alter the perception of the patients sexuality and the own personal image. Mammography is an x-ray of the mamma that allows the precocious detection of cancer, since it is capable to showing lesions in their initial stages, typically very small lesions i

3. Hydrophobicity classification in high voltage polymeric insulators / Classificação da hidrofobicidade em isoladores elétricos poliméricos de alta tensão
The aim of this study is to propose a new method to classify the hydrophobicity (HC) in high voltage polymer insulators. Currently the HC is based on the STRI guide (Swedish Transmission Research Institute) published in 1992, where the hydrophobicity is classified by contact angle and/or amount of wet surface. In the proposed method, the HC was analyzed by d

4. Shapes and textures of ferromagnetic liquid droplets
Theoretical calculations, computer simulations and experiments indicate the possible existence of a ferromagnetic liquid state. Should such a state exist, demagnetization effects would force a nontrivial magnetization texture governed by the shape of the liquid droplet. Since liquid droplets are deformable, the droplet shape couples to the magnetization text

5. Structure, surface area and morphology of aluminas from thermal decomposition of Al(OH)(CH3COO)2 crystals
Crystalline aluminium hydroxiacetate was prepared by reaction between aluminium powder (ALCOA 123) and aqueous solution of acetic acid at 96ºC ±1ºC. The white powder of Al(OH)(CH3COO)2 is constituted by agglomerates of crystalline plates, having size about 10mum. The crystals were fired from 200ºC to 1550ºC, in oxidizing atmosphere and the products char

6. Petrologia dos granitóides brasilianos associados à zona de cisalhamento Remígio-Pocinhos(PB)
The Brasiliano Cycle in the Seridó Belt (NE Brazil) is regarded mostly as a crustal reworking event, characterized by transcurrent or transpressional shear zones which operated under high temperature and low pressure conditions. In the eastern domain of this belt- the so-called São José de Campestre Massif (SJCM), a transtensional deformation regime is ev

7. Método de seleção de composições coloridas TM/Landsat para análise de classes de uso da terra / Method of selection of TM/Landsat color composition for analysis of land use classes
Este trabalho teve como objetivo a definição de composições coloridas geradas via técnicas de processamento digital (seleção de atributos e realce) que propiciassem, para a interpretação visual, melhor separabilidade de classes de uso da terra, para a região de Conchal-SP. O procedimento empregado foi baseado na composição dos alvos considerando-

8. Método de seleção de composições coloridas TM/Landsat para análise de classes de uso da terra / Method of selection of TM/Landsat color composition for analysis of land use classes
The objective of this research is to determine the colour composites generated using digital processing (feature selection and radiometric enhancement) that enhance visual interpretation and improve the separability of land use classes in Conchal, São Paulo State. The procedure used is based on a comparison among thematic classes, taking into consideration

10. A Neural Circuit Analysis of Visual Recognition Memory: Role of Perirhinal, Medial, and Lateral Entorhinal Cortex
Using a continuous recognition memory procedure for visual object information, we sequentially presented rats with eight novel objects and four repeated objects (chosen from the 8). These were selected from 120 different three-dimensional objects of varying sizes, shapes, textures, and degree of brightness. Repeated objects had lags ranging from 0 to 4 (from

11. Surface Properties of Extracellular Malaria Parasites: Morphological and Cytochemical Study 1
Morphological and cytochemical surface characteristics of isolated malaria parasites (Plasmodium berghei) and host erythrocytes were compared by electron microscopy by using thin section and carbon replica techniques. Erythrocytes were uniform in shape and had fine, granular surfaces. In contrast, free parasites exhibited a variety of sizes, shapes, and surf
