Abstract: because an enriched environment (ee) enhances t-cell activity and t-lymphocytes contribute to immunopathogenesis during heterologous dengue virus (denv) infections, we hypothesised that an ee increases dengue severity. to compare single serotype (ss) and antibody-enhanced disease (aed) infections regimens, serial intraperitoneal were performed with denv3 (genotype iii) infected brain homogenate or anti-denv2 hyperimmune serum followed 24 h later by denv3 (genotype iii) infected brain homogenate. compared aed for which significant differences were detected between the ee and impoverished environmental (ie) groups (kaplan-meyer log-rank test, p = 0.0025), no significant differences were detected between the ss experimental groups (kaplan-meyer log-rank test, p = 0.089). survival curves from ee and ie animals infected with the aed regimen were extended after corticoid injection and this effect was greater in the ee than in the ie group (kaplan-meyer log-rank test, p = 0.0162). under the aed regimen the ee group showed more intense clinical signs than the ie group. dyspnoea, tremor, hunched posture, ruffled fur, immobility, pre-terminal paralysis, shock and death were associated with dominant t-lymphocytic hyperplasia and presence of viral antigens in the liver and lungs. we propose that the increased expansion of these memory t-cells and serotype cross-reactive antibodies facilitates the infection of these cells by denv and that these events correlate with disease severity in an ee.
Theoretical Considerations about the Steady State Combustion of Wood Char in a Bubbling Fluidized Bed Reactor  [PDF]
Carlos Pinho
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.53021
Abstract:

A theoretical study on the performance of steady state bubbling fluidized bed burners is presented using a simple mathematical model. The proposed model has pedagogical and practical advantages due to its simplicity. The calculations, whose results are plotted in several graphics, were based on data obtained in laboratory scale experiments. The experiments were carried out with wood chars and the model allows a proper evaluation of physical and chemical phenomena taking place inside the reactor, as well as a fast approach to the pre-design phase, before going towards more complex and time consuming numerical modeling. In the first part of the paper the steady state modeling is compared with the combustion of successive batches of char particles. Afterwards, the performance of a 1 m diameter bed operating from 700 to 800 is shown.

Cadernos Pagu , 2005,
Abstract: O crescente panico moral acerca do "tráfico de seres humanos" tem criado uma situa o na qual os agentes que tratam do tema, ao tentar oferecer informa es concretas sobre o fen meno, muitas vezes, transformam termos de denúncias em categorias analíticas. Esse artigo analisa a produ o recente nessa área, buscando recuperar e problematizar as fontes originais acerca do "tráfico", no sentido de evidenciar como dados contraditórios s o transformados em "fatos" no processo de produ o de saberes, no qual a militancia política pode se confundir com a pesquisa científica.
Extending THREDDS middleware to serve OGC community
R. Nogueira,E. M. Cutrim
Advances in Geosciences (ADGEO) , 2006,
Abstract: Conventionally, weather products utilized in synoptic meteorology reduce phenomena occurring in four dimensions to a 2-dimensional form. This constitutes a road-block for non-atmospheric-science majors who need to take meteorology as a non-mathematical and complementary course to their major programs. This research examines the use of Integrated Data Viewer-IDV as a teaching tool, as it allows a 4-dimensional representation of weather products. IDV was tested in the teaching of synoptic meteorology, weather analysis, and weather map interpretation to non-science students in the laboratory sessions of an introductory meteorology class at Western Michigan University. Comparison of student exam scores according to the laboratory teaching techniques, i.e., traditional lab manual and IDV was performed for short- and long-term learning. Results of the statistical analysis show that the Fall 2004 students in the IDV-based lab session retained learning. However, in the Spring 2005 the exam scores did not reflect retention in learning when compared with IDV-based and MANUAL-based lab scores (short term learning, i.e., exam taken one week after the lab exercise). Testing the long-term learning, seven weeks between the two exams in the Spring 2005, show no statistically significant difference between IDV-based group scores and MANUAL-based group scores. However, the IDV group obtained exam score average slightly higher than the MANUAL group. Statistical testing of the principal hypothesis in this study, leads to the conclusion that the IDV-based method did not prove to be a better teaching tool than the traditional paper-based method. Future studies could potentially find significant differences in the effectiveness of both manual and IDV methods if the conditions had been more controlled. That is, students in the control group should not be exposed to the weather analysis using IDV during lecture.

International Journal of High Dilution Research , 2011,
Abstract: The radish is a short cycle crop, since it is harvested at 25-30 days after direct sowing. Under the economic point of view it is an important species, but there are few studies on germination of radish seeds. The objective of this study was to evaluate the effect of high diluted substances on the germination of radish seeds. The trial was conducted at the Agricultural Research Institute of Paran (IAPAR) in Londrina / Paran . It was used a pesticide free cultivar named Cometa. The treatments were: Bryonia, hydroalcoholic solution, Arnica montana, Cina and Lupine + Oat, all of them diluted and agitated at 9x; distilled water and agitated distilled water were used as controls. The mother tincture of Lupine + Oat was prepared from plants collected at the experimental station of IAPAR in Londrina. The mother tincture and all treatments were prepared according to the guidelines in the Brazilian Homeopathic Pharmacopeia, Part I [1]. The agitations of the treatments were made by a mechanical equipment, model Denise 10-50 manufactured by Autic. The water was distilled the day before preparing the treatments. The experiment was performed with 300 seeds per treatment. The seeds were placed in gerbox with germitest paper, and 50 gerbox were used per treatment, with six seeds in each gerbox. The germitest papers were moistened with the treatments and the seeds were soaked for 2 hours previously set up the experiment. The substances in high dilutions were agitated 100 times on the machine before soaking the seeds and moistening the germitest paper. The experimental design was entirely randomized and the gerbox were kept at the bench at the Laboratory of Plant Protection of IAPAR. A person not involved in conduct of the experiment coded (blinded) the treatments solutions with a random letter code. The code was kept secret until all measurements and data processing were finished. Seeds were observed daily for germination and counted only those considered germinated. Seeds were considered germinated when the radicle was at least two millimeters length. Arnica montana 9x increased 5.9% the seed germination when compared with distilled water.

Cadernos do IME : Série Estatística , 2007,
Abstract: O objetivo deste trabalho é mostrar o perfil dos estudantes cotistas que evadiram da Universidade do Estado do Rio de Janeiro nos anos de 2003 e 2004. Analisou-se o(s) principal(is) motivo(s) desta evas o e também a opini o a respeito da bolsa-auxílio oferecida; os participantes da pesquisa responderam a um questionário no período de julho a outubro de 2005. A metodologia empregada para se analisar os dados foi a Pesquisa de Mercado, sendo elaborada uma pesquisa de levantamento; também se utilizou a análise descritiva e a inferência estatística. Donde se conclui que, ao contrário do que muitos imaginam, a falta de dinheiro n o influencia na decis o dos alunos cotistas, a maior parte dos estudantes deixa a universidade ainda no 1o período e o motivo principal desse fato é a aprova o em outras universidades. Além disso, a taxa de evas o se manteve constante ao longo dos dois anos observados. Esse resultado corrobora que a entrada dos alunos cotistas n o influenciou os índices da evas o universitária e a que as solu es encontradas para reduzir esses índices devem ser aplicadas a todos os alunos sejam eles cotistas ou n o.

Fitopatologia Brasileira , 2003, DOI: 10.1590/S0100-41582003000200014
Abstract: two isolates of corynespora cassiicola obtained from tomato (lycopersicon esculentum) were tested in a greenhouse to determine their pathogenicity to squash (cucurbita pepo), barbados cherry (malpighia glabra), cowpea (vigna unguiculata), papaya (carica papaya), west indian gherkin (cucumis anguria), pepper (capsicum annum), okra (abelmoschus esculentus), soybean (glycines max), tomato and sorrel (hibiscus sabdariffa). the purpose of the study was to select plants for crop-rotation systems in tomato plantations.two weeds common to tomato plantations, commelina benghalensis and vernonia cinerea, were included to evaluate their importance as source of inoculum. the host plants tested reacted differently to the pathogen but most of them were susceptible to both isolates. this suggests that tomato plants should not be cultivated in association with or closely to squash, cucumber, pepper, okra and sorrel plantations, especially where c. cassiicola occurs. for controlling the weeds c. benghalensis and v. cinerea, it is fundamentally important reduce inoculum in the field.
