Arctiinae (lepidoptera: Erebidae) No Estado Do Rio De Janeiro, Brasil

This study describes the composition and distribution of the Arctiinae species (Lepidoptera: Erebidae) in Rio de Janeiro, generating the first list of Arctiinae species in the state. We assessed the variations in species composition and the different vegetation types in the municipalities of Rio de Janeiro. Data were collected primarily through surveys of museums and publication lists of species. We also conducted field sampling in March and September 2010. Of the 2,077 records covering 28 municipalities, 679 Arctiinae species were found in Rio de Janeiro state and were divided into two tribes and 220 genera. The location with the highest number of species recorded was Itatiaia, with 362 species, followed by Petrópolis and Angra dos Reis, with 320 and 306 species, respectively. Thirty-four percent (n = 230) of the species recorded were exclusive, i.e., occurred in only one location. The lowest dissimilarity values were observed between neighboring municipalities with the same type of plant formation, such as Petro´polis and Teresó polis (19%) or Itatiaia and Resende (24%). Some municipalities slightly further apart geographically, but with the same type of plant formation, also showed low levels of dissimilarity, for example, Petropolis and Resende (29%). However, most locations showed intermediate dissimilarity values of 40–60%, and in some cases, this figure rose to 96%. In the state of Rio de Janeiro, irrespective of its small geographical size and the predominance of a unique ecosystem, the Atlantic Forest shows a wide variation in relief, which may explain the high beta diversity values. Despite the large number of Arctiinae species recorded in Rio de Janeiro, few species were identified in areas with important forest remnants, such as Guapimirim, Nova Iguaçu, and Campos dos Goitacazes. Some regions of the northwestern part of the state were also subsampled. It is likely that new records of Arctiinae still exist in these locations, further increasing the list of Arctiinae species in Rio de Janeiro. © 2016, Universidade Estadual de Campinas UNICAMP.

First report of a norovirus outbreak associated with the variant Sydney 2012 in Portugal

Introduction: This study describes the investigation of a gastroenteritis outbreak in a group of students, associated with a dinner reunion in February 2013 in Porto, Portugal. Methodology: An anonymous structured questionnaire was developed and sent to 34 students who attended the dinner reunion. Eighteen students completed the questionnaire and thirteen met the case definition (attack rate of 72%). Stools from two students were screened for norovirus by RT-PCR using primer pairs that target the highly conserved polymerase gene and the capsid gene. Results: Norovirus genotyping confirmed the variant Sydney 2012 as the probable cause of the outbreak. Conclusion: This is the first report of an outbreak associated with the new variant Sydney 2012 in Portugal.The study was supported by FEDER funds through Programa Operacional Factores de Competividade (COMPETE), by national funding through Fundação para a Ciência e a Tecnologia (FCT) (project PTDC/CVT/113218/2009), and by grant SFRH/BD/45407/2008, and by project Ovislab ICT-2013-05-004-5314 ID-64757

Radiative processes as a condensation phenomenon and the physical meaning of deformed canonical structures

Working with well known models in $(2+1)D$ we discuss the physics behind the deformation of the canonical structure of these theories. A new deformation is constructed linking the massless scalar field theory with the self-dual theory. This is the exact dual of the known deformation connecting the Maxwell theory with the Maxwell-Chern-Simons theory. Duality is used to establish a web of relations between the mentioned theories and a physical picture of the deformation procedure is suggested.Comment: revtex4 file, 16 page

Energy production predication via Internet of Thing based machine learning system

© 2019 Elsevier B.V. Wind energy is an interesting source of alternative energy to complement the Brazilian energy matrix. However, one of the great challenges lies in managing this resource, due to its uncertainty behavior. This study addresses the estimation of the electric power generation of a wind turbine, so that this energy can be used efficiently and sustainable. Real wind and power data generated in set of wind turbines installed in a wind farm in Ceará State, Brazil, were used to obtain the power curve from a wind turbine using logistic regression, integrated with Nonlinear Autoregressive neural networks to forecast wind speeds. In our system the average error in power generation estimate is of 29 W for 5 days ahead forecast. We decreased the error in the manufacturer\u27s power curve in 63%, with a logics regression approach, providing a 2.7 times more accurate estimate. The results have a large potential impact for the wind farm managers since it could drive not only the operation and maintenance but management level of energy sells

ETNOBOTÂNICA NO PANTANAL: O SABER BOTÂNICO TRADICIONAL PANTANEIRO

  O Pantanal é uma extensa área alagável sob a influência da dinâmica hídrica, o que o torna tão peculiar. Dessa forma, os elementos da flora manifestam-se em um contexto biológico-cultural, sendo apropriados pelas populações humanas locais, consoante suas crenças e costumes. Inserida nesse cenário, a etnobotânica busca o conhecimento do ser humano sobre os recursos vegetais, visando à conservação destes. Neste texto procede-se a uma extensa revisão bibliográfica no âmbito dessa área do saber, com foco nos trabalhos desenvolvidos sobre o Pantanal, abrangendo diferentes pontos da região. Analisam-se, pois, os trabalhos voltados para essa temática, além de outros diretamente a ela correlacionados, procurando-se verificar as plantas mais citadas como fonte de recursos no território pantaneiro, as quais têm uma representação etnobotânica para os habitantes. Entre as espécies catalogadas, podem-se salientar aquelas que têm formas de uso inseridas nas seguintes etnocategorias: medicinais (Calophyllum brasiliense Cambess., Tabebuia impetiginosa (Mart. ex DC) Standl., Lafoensia pacari A. St.-Hil.); madeireira (Vochysia divergens Pohl, Callisthene fasciculata Mart.); apícola (Vernonia ferruginea Less.); ornamental (Heliconia marginata (Griggs) Pitt., Dalechampia sp.); alimentar/frutos comestíveis (Caryocar brasiliense Camb., Salacia elliptica (Mart.) G. Don); tóxica (Enterolobium contortisiliquum (Vell.) Morong., Magonia pubescens A. St.-Hil.); artesanal (Desmoncus cuyabensis Barb. Rodr., Bactris glaucescens Drude, Attalea phalerata Mart., Sapindus saponaria L.); místico-religiosa (Siparuna guianensis Aublet,. Simarouba versicolor A. St.-Hil.); iscas de pesca (Crataeva tapia L.); cultivo de subsistência (Manihot esculenta Crantz, Saccarum officinarum L.), entre outros. O conhecimento etnobotânico apreendido mostra e pode indicar mecanismos de conservação para o Pantanal enquanto importante área alagável de amplo interesse, ao se considerar a biodiversidade nos seus aspectos sociais, culturais e biológicos

Consistency analysis of a nonbirefringent Lorentz-violating planar model

In this work analyze the physical consistency of a nonbirefringent Lorentz-violating planar model via the analysis of the pole structure of its Feynman propagators. The nonbirefringent planar model, obtained from the dimensional reduction of the CPT-even gauge sector of the standard model extension, is composed of a gauge and a scalar fields, being affected by Lorentz-violating (LIV) coefficients encoded in the symmetric tensor $\kappa_{\mu\nu}$. The propagator of the gauge field is explicitly evaluated and expressed in terms of linear independent symmetric tensors, presenting only one physical mode. The same holds for the scalar propagator. A consistency analysis is performed based on the poles of the propagators. The isotropic parity-even sector is stable, causal and unitary mode for $0\leq\kappa_{00}<1$. On the other hand, the anisotropic sector is stable and unitary but in general noncausal. Finally, it is shown that this planar model interacting with a $\lambda|\varphi|^{4}-$Higgs field supports compactlike vortex configurations.Comment: 11 pages, revtex style, final revised versio

CARACTERIZAÇÃO DO MODELO INFLAMATÓRIO DE CISTITE INDUZIDA POR CICLOFOSFAMIDA EM CAMUNDONGOS SWISS

A Cistite Hemorrágica é um problema de saúde importante no mundo causado pelo uso da oxazoforinas. Apesar dos tratamentos disponíveis, há uma incidência de 2 até 40% em pacientes tratados com Ciclofosfamida (CYP). O objetivo deste trabalho foi caracterizar um modelo experimental de cistite induzida por CYP em camundongos Swiss. Para isto, camundongos fêmeas foram distribuídos em 5 grupos com 7 animais, onde 4 grupos sofreram eutanásia após 0,5, 6, 12 e 24h da aplicação de 150mg/kg de CYP via intraperitoneal. O grupo controle recebeu salina tamponada pela mesma via. Foram avaliados o peso da bexiga e seu aspecto histopatológico, o hemograma, e a contagem celular de medula óssea e linfonodo ilíaco. Os resultados demonstraram que houve aumento significativo do peso da bexiga nos tempos de 6 e 12h. Houve aumento na infamação aguda nestes dois tempos. Após 24 horas houve diminuição da resposta inflamatória aguda e início da fibrose. O número de leucócitos foi menor em todos os tempos em relação ao controle. Da mesma forma, o número de células da medula óssea foi menor nos tempos de 6, 12 e 24h. Por outro lado, o número de células do linfonodo aumentou após 12 horas. Concluímos que houve aumento progressivo da inflamação até as 12h  e que após 24h já há um processo de resolução do quadro inflamatório. Sendo assim, sugerimos a utilização do tempo de 12h como padrão experimental por ser o de maior disponibilidade de parâmetros elevados para avaliação da inflamação.Descritores: Cistite.

The Hemorragic Cystitis (HC) is an important health problem over the world caused by oxazoforines. Despite the available treatments, still have an incidence of 2 to 40% of HC in patients following treatment with Cyclophosphamide (CYP). The aim of this work was characterize a model of CYP-induced cystitis  in Swiss mice. Female mice were divided  in 5 groups with 7 animals each, 4 groups were killed 0.5, 6, 12 and 24h after an injection of CYP (150mg/kg). The control group received phosphate buffered saline at the same way. In each time the bladders were collected, weighted and prepared to histopathology analyses. The complete blood count was evaluated. The cell number from lymph nodes and bone marrow was quantified. The results showed that bladder weight was increased at 6thand 12th hour pos cystitis induction. There was acute inflammation increased after 6 and 12h. After 24h there was an initial fibrosis. The leucocytes count was decreased in all times. The cells number was decreased at 6th,12th, and 24th hours in bone marrow and it was increased at 12th in lymph nodes. We concluded that there is an increase in inflammatory parameters until the 12th hour pos CYP injection which are decreased at 24th hour. We suggest using the time of 12h as the standard experimental time because of the biggest availability parameters for evaluating.Descriptors: Cyclophosphamide. Cystitis. Mice. Experimental model
