No full textThe study was conducted at the Experimental Garden of the Faculty of Agriculture, Asahan University, Kisaran Naga Village, Kota Kisaran Timur Subdistrict, Asahan Regency, North Sumatra Province with a flat topography and a height of ± 25 m above sea level, with sufficient water sources with sandy clay texture. The study was conducted in April to June 2018. This study was arranged based on Factorial Randomized Block Design (RBD) with two treatment factors and three replications, the first factor was the dose of rabbit feces fertilizer (K) consisting of 4 levels, namely K0 (without treatment), K1 (0.29 kg / plot) , K2 (0.58 kg / plot), and K3 (0.87 kg / plot), and the second fator is NPK BOOS 324 (N) fertilizer consisting of 3 levels namely N0 (control), N1 (10.8 g / plot), and N2 (21.6 g / plot). The results showed that the treatment of rabbit feces fertilizer had a significant effect on the growth and production of purple eggplant plants. The best treatment was at a dose of 0.87 kg / plot (K3) resulting in plant height of 53.26 cm, number of fruit 8.33 fruit, production per plant 1.13 kg and production per plot of 17.00 kg. NPK BOOS 324 fertilizer treatment significantly affected the growth and production of purple eggplant plants. The best treatment was found in the treatment of 21.6 g / plot (N2) resulting in the highest plant height of 53.26 cm, number of fruits of 8.00 fruit, production per plant of 1.00 kg and production per plot of 15.63 kg. The interaction of giving rabbit feces fertilizer and NPK BOOS 324 fertilizer did not show a significant effect on the growth of purple eggplant
Contribuição ao reconhecimento automático de padrões epileptiformes em sinais de eletroencefalograma utilizando análise morfológica
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Elétrica, Florianópolis, 2015.A análise do sinal de eletroencefalograma (EEG) pode ser uma importante ferramenta de auxílio à comprovação clínica do diagnóstico de epilepsia. Esta análise é uma verificação visual criteriosa de registros de EEG na busca por uma atividade eletrográfica específica denominada descarga ou padrão epileptiformes. Essa atividade, quando encontrada com determinada frequência, pode corroborar o diagnóstico de epilepsia. No entanto, como os registros analisados normalmente são resultado de longos períodos de monitoramento, a análise do EEG pode ser um processo demorado. Diversos estudos propuseram metodologias ou sistemas para automatizar este tipo de análise, mas apesar dos esforços e relativo sucesso ainda não existe um algoritmo ou sistema para este reconhecimento automático que seja amplamente difundido no ambiente clínico, possua um desempenho de acordo com as necessidades dos especialistas na área e, do ponto de vista técnico, não possua restrição quanto aos dados de entrada. Desta forma, com o intuito de contribuir para o estudo do reconhecimento automático de padrões epileptiformes o presente trabalho descreve uma proposta de metodologia baseada em análise morfológica e inspirada no comportamento dos especialistas humanos. A análise morfológica é realizada utilizando um conjunto de descritores morfológicos extraídos de sinais de EEG processados digitalmente. A avaliação da metodologia é realizada utilizando um grupo de classificadores computacionais e diferentes bases de dados de EEG. O desempenho da metodologia é analisado por métricas consolidadas na literatura e por uma comparação pareada com o desempenho de sensibilidade, especificidade e concordância de quatro neurofisiologistas clínicos. Resultados obtidos mostraram que o classificador que apresentou o melhor desempenho geral foi uma rede neural combinada com a Análise de Componentes Principais. A sensibilidade e a especificidade média atingida por essa rede foram, respectivamente 58,6 e 87,2%. A eficiência média obtida pela rede nas bases de dados foi de 89%. E a concordância dessa rede com os quatro especialistas foi de 45,7%. Os resultados obtidos para a especificidade mostraram-se satisfatórios, uma vez que os valores médios obtidos foram compatíveis àqueles dos especialistas. Apesar da sensibilidade e da concordância com os especialistas terem apresentado valores baixos, pode-se considerar que a metodologia proposta apresenta resultados promissores considerando a quantidade e natureza dos testes realizados.Abstract : The analysis of the EEG signal (EEG) can be an important support tool to the clinical confirmation of the diagnosis of epilepsy. This analysis is a thorough visual inspection of EEG recordings in the search for a specific electrographic activity called epileptiform pattern or discharge. This activity, when found with a certain frequency, can corroborate the diagnosis of epilepsy. However, as the analyzed recordings are usually the result of long term monitoring, the EEG analysis can be a time consuming process. Several studies have proposed methodologies and/or systems to automate this type of analysis however despite the efforts and relative success, there is still no solution for the automatic recognition that is widely disseminated in the clinical environment, has a performance according to the needs of specialists in the field and, from a technical point of view has no restriction about the input data. Thus, in order to contribute to the study of automatic recognition of epileptiform patterns this work describes a methodology proposal based on morphological analysis and inspired by the behavior of human experts. The morphological analysis is performed using a set of morphological descriptors extracted from digitally processed EEG signals. The evaluation of the methodology is performed using a group of computational classifiers and different EEG databases. The methodology?s performance is analyzed by metrics consolidated in the literature and by a pairwise comparison of the sensitivity, specificity and agreement of four clinical neurophysiologists. Obtained results show that the classifier that presented the best overall performance was a neural network combined with the Principal Component Analysis. The average sensitivity and specificity achieved by this network were respectively 58.6 and 87.2%. The network?s average efficiency obtained in the databases was 89%. And the agreement of the network with four experts was 45.7%. The results for specificity were satisfactory, since the average values obtained were consistent to those of the experts. Despite the low values of sensitivity and agreement with the experts presented by the classifiers, it can be considered that the proposed methodology shows promising results considering the amount and nature of the tests performed in this work
Dual pairs of sequence spaces
No full textThe paper aims to develop for sequence spaces E a general concept for reconciling certain results, for example inclusion theorems, concerning generalizations of the Köthe-Toeplitz duals E×(×∈{α,β}) combined with dualities (E,G),G⊂E×, and the SAK-property (weak sectional convergence). Taking
Eβ:={(yk)∈ω:=ℕ|(ykxk)∈cs}=:Ecs, where cs denotes the set of all summable sequences, as a starting point, then we get a general substitute of Ecs by replacing cs by any locally convex sequence space S with sum s∈S′ (in particular, a sum space) as defined by Ruckle (1970). This idea provides a dual pair (E,ES) of sequence spaces and gives rise for a generalization of the
solid topology and for the investigation of the continuity of
quasi-matrix maps relative to topologies of the duality
(E,Eβ). That research is the basis for general versions of three types of inclusion theorems: two of them are originally due to Bennett and Kalton (1973) and generalized by the authors (see Boos and Leiger (1993 and 1997)), and the third was done by
Große-Erdmann (1992). Finally, the generalizations, carried out in this paper, are justified by four applications with results around different kinds of Köthe-Toeplitz duals and
related section properties
Frizzled Proteins are bona fide G Protein-Coupled Receptors
No full textReceptors of the Frizzled family initiate Wnt ligand-dependent signaling controlling
multiple steps in organism development and highly conserved in evolution.
Misactivation of the Wnt/Frizzled signaling is cancerogenic. Frizzled receptors
launch several signaling cascades: the canonical pathway regulating beta-catenin-dependent transcription; the planar cell polarity pathway polarizing the
cytoskeleton within the epithelial plane; and the calcium pathway. Frizzled
receptors possess seven transmembrane domains and their signaling depends on
trimeric G proteins in various organisms. However, Frizzleds constitute a
distinct group within the G protein-coupled receptors (GPCR) superfamily, and
Frizzled signaling can be G protein-independent in some experimental setups, which led to concerns about the GPCR nature of Frizzled. Here we demonstrate
that human Frizzled receptors can directly bind the trimeric Go protein in a
pertussis toxin-sensitive manner. Furthermore, addition of Wnt ligands elicits
Frizzled-dependent guanine nucleotide exchange on Go. An excess of secreted
Frizzled-related protein (a Wnt antagonist) prevents Go activation, as does
pretreatment of Go with pertussis toxin. These experiments provide a biochemical
proof of the GPCR activities of Frizzled receptors and establish an in vitro assay to
monitor Frizzled activation by Wnt ligands, applicable for the high-throughput
agonist/antagonist screening
Caracterização histológica e imuno-histoquímica das lesões de tuberculose em bovinos e de linfadenite granulomatosa em suínos.
No full textMycobacterium sp. induz inflamação granulomatosa em diferentes espécies animais. Mycobacterium bovis e o complexo Mycobacterium avium são importantes patógenos de bovinos e suínos e podem causar infecção em humanos, principalmente imunossuprimidos. Perdas na produção, barreiras comerciais e prejuízos por condenação de carcaças em abatedouro/frigorífico estão atrelados à ocorrência dessas infecções, com prejuízos econômicos significativos. Foi realizado um estudo de casos diagnosticados como tuberculose em bovinos e linfadenite granulomatosa em suínos no Setor de Patologia Veterinária da Universidade Federal do Rio Grande do Sul (SPV-UFRGS) no período de janeiro de 2007 a dezembro de 2011. Dados referentes à raça, ao sexo, à idade e ao histórico clínico foram compilados dos livros de registro e analisados. As características histológicas das lesões em linfonodos e pulmões foram avaliadas em Hematoxilina-Eosina, com predomínio de células gigantes nas lesões de tuberculose bovina e de macrófagos epitelioides em suínos. As técnicas histoquímicas de Ziehl-Neelsen e Tricrômico de Masson foram utilizadas para evidenciar, respectivamente, bacilos álcool-ácido resistentes e tecido conjuntivo fibroso nas lesões. A técnica de imuno-histoquímica foi utilizada em aproximadamente 30% dos casos estudados de cada espécie, selecionados aleatoriamente, para a caracterização do infiltrado linfocítico. Foram utilizados os anticorpos anti-CD3 para a marcação de linfócitos T e anti-CD79?cy para a marcação de linfócitos B. Linfócitos T predominaram nas lesões em ambas as espécies, com diferença estatisticamente significativa entre as médias dos linfócitos T e linfócitos B. Foi usado o teste tpareado, com t=5,501 (p<0,001) nas lesões dos bovinos e , t=5,826 (p<0,001) para as lesões de linfadenite dos suínos. Adicionalmente foram marcados macrófagos com o uso do anticorpo anti-CD68 para bovinos e anti-Lisozima para suínos. Além desses, o anticorpo policlonal anti-Mycobacterium tuberculosis foi utilizado para a detecção de bactérias do gênero Mycobacterium, com imunomarcação positiva em todos os casos e, nos casos dos suínos, houve marcação anti-Mycobacterium avium
Gender Inequality in the Wealth of Older Canadians
No full textBeyond income, wealth is an important measure of economic well-being, because while income captures the current state of inequality, wealth has the potential for examining accumulated and historically structured inequality. This paper documents the extent of gender inequality in wealth for Canadian women and men aged 45 and older. The analysis uses data from the 1999 Canadian Survey of Financial Security, a large nationally representative survey of household wealth in Canada. Wealth is measured by total net worth as measured by total assets minus debt. We test two general hypotheses to account for gender differences in wealth. The differential exposure hypothesis suggest that women report less wealth accumulation because of their reduced access to the material and social conditions of life that foster economic security. The differential vulnerability hypothesis suggests that women report lower levels of wealth because they receive differential returns to material and social conditions of their lives. Support is found for both hypotheses. Much of the gender differences in wealth can be explained by the gendering of work and family roles that restricts women’s ability to build up assets over the life course. But beyond this, there are significant gender interaction effects that indicate that women are further penalized by their returns to participation in family life, their health and where they live. When women do work, net of other factors, they are better able to accumulate wealth than their male counterparts.wealth, retirement, net assets, gender differences
Dijet Azimuthal Decorrelations in pp Collisions at root s=7 TeV
No full textMeasurements of dijet azimuthal decorrelations in pp collisions at root s = 7 TeV using the CMS detector at the CERN LHC are presented. The analysis is based on an inclusive dijet event sample corresponding to an integrated luminosity of 2: 9 pb(-1). The results are compared to predictions from perturbative QCD calculations and various Monte Carlo event generators. The dijet azimuthal distributions are found to be sensitive to initial-state gluon radiation.
