An analog implementation of radial basis neural networks (RBNN) using BiCMOS technology

This paper describes a analog implementation of radial basis neural networks (RBNN) in BiCMOS technology. The RBNN uses a gaussian function obtained through the characteristic of the bipolar differential pair. The gaussian parameters (gain, center and width) is changed with programmable current source. Results obtained with PSPICE software is showed.

Ectrópio palpebral em portador da síndrome de Down e conjuntivite alérgica: Relato de caso

This is a case report of a patient with Down's syndrome with an important mechanical ectropion and elongation of the lower lid related to chronic allergic conjunctivitis, besides cataract and keratoconus. The tarsal strip technique and ressection of redundant and thick conjunctiva was the surgical approach chosen for this case. Functional and cosmetic outcomes were considered satisfactory.

Propagation of ship waves on a sloping bottom

The numerical model FUNWAVE was adapted in order to simulate the generation and propagation of ship waves to shore, including phenomena such as refraction, diffraction, currents and breaking of waves. Results are shown for Froude numbers equal to 0.8, 1.0 and 1.1, in order to verify the refraction of the wave pattern, identify breaking conditions and to investigate the wave generation scheme as a moving pressure at the free surface. © 2009 World Scientific Publishing Co.

Balance of pH of chicks from eggs injected with ascorbic acid and subjected to thermal stress

This study aimed to verify that chicks from eggs injected with ascorbic acid and subjected to heat stress would have changes in acid-base balance, compared to chicks incubated at thermoneutral without injection of ascorbic acid. The parameters evaluated were blood pressure of carbon dioxide and oxygen, base excess, total carbon dioxide, concentration of sodium, potassium, ionized calcium, bicarbonate and pH of newly hatched male chicks, hatched from eggs injected with acid ascorbic acid (AA) and subjected to heat stress during incubation. The experimental design was completely randomized in factorial scheme 5 (application levels of ascorbic acid) x 2 (incubation temperatures). The data were subjected to analysis of variance using the General Linear Model procedure (GLM) of SAS ®. For the blood pH was observed significant interaction (p <0.05) between treatments with application in eggs and incubation temperatures. For the other parameters were not significant effects (p< 0.05) of AA level and neither temperature of incubation. Analyzing the unfolding of the interaction to pH was observed that chicks from eggs injected with 6% ascorbic acid and subjected to heat stress during incubation had a higher pH value compared with the thermoneutral temperature incubated (p <0.05). Therefore, it is suggested that the incubation of eggs in high temperature (39°C) can alter the metabolic rate of these embryos.

Abundância, composição e diversidade de Arctiinae (Lepidoptera, Arctiidae) em um fragmento de floresta na Amazônia Oriental em Altamira, PA, Brasil

Este estudo avaliou a fauna de Arctiinae em um fragmento de floresta primária em Altamira, Pará, na Amazônia Oriental brasileira. As mariposas foram amostradas durante dois anos (de agosto de 2007 a julho de 2009), com auxílio de armadilha luminosa. Foram medidos os seguintes parâmetros: riqueza, abundância, constância, índices de diversidade e uniformidade de Shannon (H' e E') e de Brillouin (H e E) e o índice de dominância de Berger-Parker (BP). As estimativas de riqueza, foram efetuadas através dos procedimentos não paramétricos, "Bootstrap", "Chao 1", "Chao 2", "Jackknife 1", "Jackknife2" e "Michaelis-Mentem". Foram capturados 466 exemplares pertencentes a 78 espécies de Arctiinae, das quais 12 são novos registros para o Estado. Os valores dos parâmetros analisados para todo o período foram: H'= 3,08, E'= 0,708, H= 2,86, E= 0,705 e BP= 0,294. As comunidades dos meses menos chuvosos foram mais diversas. Os estimadores previram o encontro de 17 a 253 espécies a mais.
