Analyzing the fluidization of a mixture of gas-sand-biomass using cfd techniques

Fluidization taking into account the presence of the material to be gasified is a differential addressed in this study. Accordingly the solid phase was composed of a binary mixture of sand and biomass. This paper deals with the numerical simulation of a gasifier bubbling fluidized bed using CFD for the system composed of gas - biomass – sand. In order to determine the best fluidization conditions, a factorial design 23 was carried out varying the biomass particle density and diameter and the biomass percentage in the solid phase. To perform the simulations, ANSYS CFX 15.0 was used, adopting an Eulerian approach coupled to the Kinetic Theory of Granular Flow. The k- ε turbulence model was adopted. Seventeen simulations were performed setting the gas superficial velocity to 0.38 m s-1. Based on the results of the factorial design, it was possible to qualitatively identify the tests to which the system reached a bubbling fluidization (1, 2, 5, 6, 9, 11, 12 and 14). The variable with the highest significance in the model equation was the diameter of the biomass particle. Volumetric fraction profiles of gas, sand and biomass were obtained to the 17 factorial design conditions as well as a model that predicts the bed expansion. The assay that reached greater bed height (0.50 m), staying on bubbling regime, was the one with 15% biomass particles with 375 m diameter and 85% sand, indicating those are good conditions for fluidization.

Lethality by pneumonia and factors associated to death

AbstractObjectiveto describe the case-fatality rate (CFR) and risk factors of death in children with community-acquired acute pneumonia (CAP) in a pediatric university hospital.Methoda longitudinal study was developed with prospective data collected from 1996 to 2011. Patients aged 1 month to 12 years were included in the study. Those who left the hospital against medical orders and those transferred to ICU or other units were excluded. Demographic and clinical-etiological characteristics and the initial treatment were studied. Variables associated to death were determined by bivariate and multivariate analysis using logistic regression.Resultsa total of 871 patients were selected, of whom 11 were excluded; thus 860 children were included in the study. There were 26 deaths, with a CFR of 3%; in 58.7% of these, penicillin G was the initial treatment. Pneumococcus was the most common pathogen (50.4%). From 1996 to 2000, there were 24 deaths (93%), with a CFR of 5.8% (24/413). From 2001 to 2011, the age group of hospitalized patients was older (p = 0.03), and the number of deaths (p = 0.02) and the percentage of disease severity were lower (p = 0.06). Only disease severity remained associated to death in the multivariate analysis (OR = 3.2; 95%CI: 1.2-8.9; p = 0.02).Conclusionwhen the 1996-2000 and 2001-2011 periods were compared, a significant reduction in CFR was observed in the latter, as well as a change in the clinical profile of the pediatric inpatients at the institute. These findings may be related to the improvement in the socio-economical status of the population. Penicillin use did not influence CFR

Sexual dimorphism, female fertility, and diet of Physalaemus feioi (Anura: Leptodactylidae) from southeastern Brazil

Physalaemus feioi é uma rã da América do Sul, endêmica da Mata Atlântica, registrada nos estados de Minas Gerais e São Paulo. Avaliamos o dimorfismo sexual, a fertilidade nas fêmeas e dieta dessa espécie em duas localidades do estado de Minas Gerais, incluindo a localidade-tipo da espécie. Coletamos 73 indivíduos (16 fêmeas adultas e 57 machos adultos) por meio de busca ativa. O número de oócitos encontrados para P. feioi (x̅ = 1385 ± 498,13) foi alto quando comparado com outras espécies do gênero como P. maculiventris, P. signifer, P. cuvieri e P. ephippifer mas este semelha o número de oócitos de P. centralis, P. kroyeri e P. marmoratus. As presas com maior índice de importância foram Coleoptera (IIR = 24,26) e Formicidae (IIR = 16,46). Não houve diferenças entre machos e fêmeas quanto ao número de presas ingeridas e nem o volume do conteúdo estomacal. Em resumo, Physalaemus feioi teve semelhanças com outras espécies do gênero em relação ao dimorfismo sexual, fecundidade e hábitos alimentares.Physalaemus feioi is a South American frog endemic to the Brazilian Atlantic Forest that occurs in the states of Minas Gerais and São Paulo. We evaluated sexual dimorphism, female fertility, and diet of P. feioi from two locations in the state of Minas Gerais, including the type locality of the species. We collected 73 individuals (16 adult females and 57 adult males). The number of oocytes of P. feioi (x̅ = 1385 ±498.13) was higher than in other species of the genus, such as P. maculiventris, P. signifer, P. cuvieri, and P. ephippifer, but it resembles that of P. centralis, P. kroyeri, and P. marmoratus. The prey items with the highest index of importance were Coleoptera (IIR = 24.26) and Formicidae (IIR = 16.46). We found no sex differences regarding the number of ingested prey and the volume of the stomach contents. In summary, Physalaemus feioi was similar to other species of the genus regarding sexual dimorphism, fecundity, and feeding habits

Analytical Model for Predesigning Probe-Fed Hybrid Microstrip Antennas

Based on the equivalent resonant cavity model, an effective analysis methodology of probe-fed hybrid microstrip antennas is carried out in this paper, resulting in a better understanding of the parameter interrelations affecting their behavior. With that, a new design criterion focused on establishing uniform radiation patterns with balanced 3 dB angles is proposed and implemented. Results obtained with the proposed model closely matched HFSS simulations. Measurements made on a prototype antenna, manufactured with substrate integrated waveguide (SIW) technology, also showed excellent agreement, thus validating the use of the cavity model for predesigning hybrid microstrip antennas in a simple, visible, and time- and cost-effective way

Alkaloids in Erythrina

Erythrina species are used in popular medicine as sedative, anxiolytic, anti-inflammatory, and antihypertensive. In this work, we investigated the chemical composition of extracts obtained from leaves of E. falcata and E. crista-galli. The hypotensive potential of E. falcata and the mechanism of action were also studied. The extracts were obtained by maceration and infusion. The total content of phenolic compounds and flavonoids was estimated by spectrophotometric methods. The chemical constituents were studied performing a chromatographic analysis by UPLC-ESI-MS. For in vivo protocols, blood pressure and heart rate were measured by the invasive hemodynamic monitoring method. Different concentrations of extracts and drugs such as L-NAME, losartan, hexamethonium, and propranolol were administrated i.v. The results of total phenolic contents for E. falcata and E. crista-galli were 1.3193–1.4989 mgGAE/mL for maceration and 0.8771–0.9506 mgGAE/mL for infusion. In total flavonoids, the content was 7.7829–8.1976 mg RE/g for maceration and 9.3471–10.4765 RE mg/g for infusion. The chemical composition was based on alkaloids, suggesting the presence of erythristemine, 11β-methoxyglucoerysodine, erysothiopine, 11β-hydroxyerysodine-glucose, and 11-hydroxyerysotinone-rhamnoside. A potent dose-dependent hypotensive effect was observed for E. falcata, which may be related to the route of β-adrenergic receptors

Processamento de Leite Fermentado Probiótico com um Preparado de Albúmen Sólido de Coco Verde.

O coco verde é muito consumido no Brasil, sendo basicamente utilizado na produção da água de coco (albúmen líquido). A água de coco verde corresponde a aproximadamente 25% do peso do fruto in natura, ou seja, a industrialização resulta em uma grande quantidade de resíduo. O albúmen sólido do coco, em geral, é descartado junto com as cascas. Os leites fermentados podem ter adição de outras substâncias alimentícias, tais como sucos, pedaços, preparados ou polpas de frutas em uma concentração máxima de 30% em relação à massa final do produto. A adição de preparados de frutas conferem diferentes experiências sensoriais, agregando valor ao leite fermentado. A utilização do albúmen sólido de coco verde para elaboração um preparado para conferir aroma e sabor de coco verde ao leite fermentado potencialmente probiótico é uma alternativa interessante e viável. A concentração de probióticos no produto varia de 10 8 UFC/g (primeira semana) a 10 6 UFC/g (quarta semana de armazenagem). A quantidade observada até a quarta semana de armazenagem é suficiente para conferir uma possível alegação funcional de probiótico. De acordo com a legislação brasileira, as contagens de Bifidobacterium em leite fermentados devem ficar acima de 10 6 UFC/g (Brasil, 2007). O produto tem uma boa aceitação sensorial, com relação ao sabor, aroma e aceitação global, alcançando nota média de 7,0 em uma escala hedônica de nove pontos. O produto tem pouca pós-acidificação durante estocagem, com uma variação de pH de 4,73 a 4,91 ao longo da estocagem refrigerada. Nesta publicação é descrito o processo para obtenção de um leite fermentado probiótico com adição de 30% de preparado de albúmen sólido de coco verde para agregar valor à esta matéria-prima e conferir sabor e aroma de coco verde ao leite fermentado

Causes of variation in BCG vaccine efficacy: examining evidence from the BCG REVAC cluster randomized trial to explore the masking and the blocking hypotheses.

BCG protection varies and in some places (nearest the equator) is low or absent. Understanding this variation can inform the efforts to develop new vaccines against tuberculosis. Two main hypotheses are used to explain this variation: under masking, new vaccines are unlikely to increase protection; under blocking new vaccines have a greater potential to be effective when BCG is not. We conducted a cluster randomized trial to explored the masking and blocking hypotheses by studying BCG vaccine efficacy of neonatal vaccination and when administered for the first or a second (revaccination) time at school age in two sites (Manaus close and Salvador further south from the equator). Seven hundred and sixty three state schools were matched on socio economic characteristics of the neighborhood and 239,934 children were randomized to vaccine (BCG vaccination at school age) or control group. Protection by first BCG vaccination at school age was high in Salvador (34%, 95% CI 7-53%, p=0.017) but low in Manaus (8%, 95% CI t0 39-40%, p=0.686). For revaccination at school age, protection was modest in Salvador (19%, 95% CI 3-33%, p=0.022) and absent in Manaus (1%, 95% CI to 27-23%, p=0.932). Vaccine efficacy for neonatal vaccination was similar in Salvador (40%, 95% CI 22-54%, p<0.001) and Manaus (36%, 95% CI 11-53%, p=0.008). Variation in BCG efficacy was marked when vaccine was given at school age but absent at birth, which points towards blocking as the dominant mechanism. New tuberculosis vaccines that overcome or by pass this blocking effect could confer protection in situations where BCG is not protective
