Reply to "Comment on Renormalization group picture of the Lifshitz critical behaviors"
We reply to a recent comment by Diehl and Shpot (cond-mat/0305131)
criticizing a new approach to the Lifshitz critical behavior just presented (M.
M. Leite Phys. Rev. B 67, 104415(2003)). We show that this approach is free of
inconsistencies in the ultraviolet regime. We recall that the orthogonal
approximation employed to solve arbitrary loop diagrams worked out at the
criticized paper even at three-loop level is consistent with homogeneity for
arbitrary loop momenta. We show that the criticism is incorrect.Comment: RevTex, 6 page
Waves of family hope: narratives of families in the context of pediatric chronic illness
Incluye versión en inglésObjetivo: analizar las narrativas sobre la experiencia de esperanza de las familias en el contexto de la enfermedad crónica pediátrica. Método: investigación narrativa que utilizó la Enfermería de Sistemas Familiares como marco conceptual. En este estudio participaron tres familias de niños y adolescentes diagnosticados con enfermedades crónicas complejas, con un total de 10 participantes. La recogida de datos se desarrolló mediante entrevistas familiares con foto-elicitación. Se construyeron y analizaron narrativas familiares siguiendo el análisis temático inductivo con triangulación teórica de los de datos. Resultados: el tema analítico - Olas de esperanza familiar en el contexto de la enfermedad crónica pediátrica - se compone de cuatro tipos diferentes de esperanza: esperanza incierta, esperanza cuidadora, esperanza latente y esperanza expectante. El movimiento a través de estas esperanzas genera una fuerza motriz y dependiente de varios factores: apoyo, información, búsqueda de la normalidad, pensamientos y comparaciones. Conclusión: los resultados destacan la interacción y reciprocidad de los miembros de la unidad familiar, la dinámica de la esperanza, e ilustran los diferentes tipos de esperanza y los factores que los influyen. Este estudio destaca la experiencia de la esperanza como un recurso familiar, en vez de un recurso individual, y apoya a los profesionales de la salud en la planificación del cuidado familiar considerando la esperanza como un recurso familiar esencial y dinámico.Objective: to analyze narratives about the experience of hope of families in the context of pediatric chronic illness. Method: a narrative research using Family Systems Nursing as a conceptual framework. Three families of children and adolescents diagnosed with complex chronic illness participated in this study, totaling 10 participants. Data collection was developed using family photo-elicitation interviews. Family narratives were constructed and analyzed according to inductive thematic analysis with theoretical data triangulation. Results: the analytical theme – Waves of Family Hope in the Context of Pediatric Chronic Illness – is composed of four different types of hope: uncertain hope, caring hope, latent hope, and expectant hope. Movement through these hopes generates a driving energy and depends on a number of factors: support, information, searching for normality, and thoughts and comparisons. Conclusion: the results highlight the interaction and reciprocities of the members of the family unit, and the dynamics of hope, and illustrate the different types of hope and the factors that influence them. This study highlights the experience of hope as a family resource rather than just an individual resource, and supports health professionals in the planning of family care considering hope as an essential and dynamic family resource. © 2021 Revista Latino-Americana de Enfermagem.This study was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) – Finance Code 001, and by Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), Brazil
ENDOPARASITAS EM CÃES (Canis familiaris) NA CIDADE DE CURITIBA PARANÁ BRASIL
O presente trabalho analisa prospectivamente as infecções múltiplas e isoladas em cães
de estudantes de quatro instituições de ensino de Curitiba PR, através de exames de 264 amostras
de fezes, colhidas no período de abril a julho de 2000 e examinadas de acordo com a técnica de
WILLIS (1921). A infecção isolada causada por Ancylostoma sp. foi observada em maior porcentagem,
seguida da parasitose múltipla pela associação Ancylostoma sp./Toxocara sp.
Enteroparasites in dogs (Canis familiaris) from Curitiba, Paraná, Brasil
Abstract
The present study demonstrates the multiple and isolated infections caused by
enteroparasites in dogs belonged to students of four schools from Curitiba, PR, by examination of 264
fecal samples, collected from April to July, 2000, and analyzed by the WILLIS (1921) technique. The
isolated infection by Ancylostoma sp. was the highest percentage observed, while Ancylostoma sp.
and Toxocara sp. were the multiple parasites most frequently found
The brain decade in debate: II. Panic or anxiety? From animal models to a neurobiological basis
This article is a transcription of an electronic symposium sponsored by the Brazilian Society of Neuroscience and Behavior (SBNeC). Invited researchers from the European Union, North America and Brazil discussed two issues on anxiety, namely whether panic is a very intense anxiety or something else, and what aspects of clinical anxiety are reproduced by animal models. Concerning the first issue, most participants agreed that generalized anxiety and panic disorder are different on the basis of clinical manifestations, drug response and animal models. Also, underlying brain structures, neurotransmitter modulation and hormonal changes seem to involve important differences. It is also common knowledge that existing animal models generate different types of fear/anxiety. A challenge for future research is to establish a good correlation between animal models and nosological classification.Universidade Federal do Paraná Departamento de Farmacologia Laboratório de Fisiologia e Farmacologia do Sistema Nervoso CentralUniversity of Hawaii Department of NeurobiologyUniversity of Hawaii Department of PsychologyUniversidade de São Paulo Faculdade de Filosofia Ciências e Letras de Ribeirão Preto Departamento de PsicobiologiaUniversidade de São Paulo Faculdade de Medicina de Ribeirão Preto Departamento de FisiologiaUniversidade de São Paulo Faculdade de Medicina de Ribeirão Preto Departamento de NeuropsiquiatriaUniversidade Federal de Santa Catarina Departamento de FarmacologiaCentral Nervous System Research Department Sanofi SynthelaboAston University Institute of Pharmaceutical SciencesHoffmann-La Roche Ltd.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de PsicologiaUniversity of Leeds Department of Psychology Ethopharmacology LaboratoryUniversidade Federal do Espírito Santo Centro de Biomedicina Departamento de Ciências FisiológicasUNIFESP, EPM, Depto. de PsicologiaSciEL
LESÕES ANATOMOPATOLÓGICAS PRESENTES NA INFECÇÃO POR DIOCTOPHYMA RENALE (GOEZE, 1782) EM CÃES DOMÉSTICOS (CANIS FAMILIARIS,) LINNAEUS, 1758
Os autores descrevem as lesões anatomopatológicas de onze casos de parasitismo
por Dioctophyma renale (Goeze, 1782), na cidade de Curitiba - PR, Brasil, constatados em necrópsias
e achados clínicos em 1960 cães, no período de 1979 a 2004.
Anatomopathologic lesions found in Dioctophyma renale (Goeze, 1782) infections in
domestic dogs (Canis familiaris, LINNAEUS, 1758
Abstract
The authors describe the anatomopathologic lesions of eleven cases of parasitism by
Dioctophyma renale (Goeze, 1782), in Curitiba (PR, Brazil), found among 1960 necropsies carried
out between 1979 and 2004 in dogs
Susceptibility amplitude ratio for generic competing systems
We calculate the susceptibility amplitude ratio near a generic higher
character Lifshitz point up to one-loop order. We employ a renormalization
group treatment with independent scaling transformations associated to the
various inequivalent subspaces in the anisotropic case in order to compute the
ratio above and below the critical temperature and demonstrate its
universality. Furthermore, the isotropic results with only one type of
competition axes have also been shown to be universal. We describe how the
simpler situations of -axial Lifshitz points as well as ordinary
(noncompeting) systems can be retrieved from the present framework.Comment: 20 pages, no figure
Uso da adubação orgânica e cobertura morta na cultura da calêndula (Calendula officinalis L.).
A calêndula representa fonte alternativa econômica principalmente para a agricultura familiar. O objetivo do presente trabalho foi avaliar os efeitos da adubação orgânica e do uso da cobertura morta sobre a produção de biomassa e teor de flavonóides totais em plantas de calêndula. O experimento foi realizado no Campus de Montes Claros da Universidade Federal de Minas Gerais, utilizando-se o delineamento em blocos casualizados em esquema fatorial 2x2x4 com quatro repetições: duas épocas de colheita, presença ou ausência de cobertura morta e quatro doses de composto orgânico (0, 30, 60 e 90 t ha-1). As maiores produções de biomassa e flavonóides totais foram verificadas com o aumento das doses de composto orgânico. Para os flavonóides totais o maior teor foi obtido na segunda colheita na presença de cobertura morta
Surface critical exponents at a uniaxial Lifshitz point
Using Monte Carlo techniques, the surface critical behaviour of
three-dimensional semi-infinite ANNNI models with different surface
orientations with respect to the axis of competing interactions is
investigated. Special attention is thereby paid to the surface criticality at
the bulk uniaxial Lifshitz point encountered in this model. The presented Monte
Carlo results show that the mean-field description of semi-infinite ANNNI
models is qualitatively correct. Lifshitz point surface critical exponents at
the ordinary transition are found to depend on the surface orientation. At the
special transition point, however, no clear dependency of the critical
exponents on the surface orientation is revealed. The values of the surface
critical exponents presented in this study are the first estimates available
beyond mean-field theory.Comment: 10 pages, 7 figures include
