A Política Monetária Recente: Alguns Aspectos Críticos

Este Artigo tem como Objetivo Apresentar uma Análise das Práticas Atuais da Política Monetária, a Política de Regras Monetárias . Discute o Contexto Histórico em que Tais Práticas Apareceram, e suas Implicações, Especialmente de que a Oferta Monetária Passa a ser é Endógena, e não Exógena, como na Visão Monetarista Tradicional. a Nova Doutrina Também Faz a Suposição Extrema de que Embora a Política Monetária Possa ser Efetiva no Curto Prazo, Ela é Neutra no Longo Prazo. esta Hipótese Bem como suas Implicações para a Política Monetária Podem ser Sujeitas a Várias Críticas que Serão Desenvolvidas neste Trabalho.

O acolhimento da gravidez em comunidade cristã: os desafios da responsabilidade parental

This article is situated in the context of family planning with the objective of identifying how much pastoral agents of a Christian community welcomed the pregnancy of the fi rst child. Method: This work is the fruit of a bibliographical and fi eld research held with 278 pastoral agents of the Diocese of Jacarezinho, Paraná State, southern Brazil. The research was carried out from the application of questionnaire: Parenting planning in the context of bioethics. The sample studied showed a profile predominantly female, over the age of 46 years, with fewer than three children, married and with complete high school education or above. Result: This article explores the response to the question: ‘What was your reaction to the announcement of the pregnancy of the first child?’ According to the possibilities of answers submitted the result was as follows: 0.5% revolt, 13.1% concern, surprise 4.7%, 7.9% acceptance and joy 64.8%. These data were crossed and explored from the perspective of gender, age of first pregnancy, marital status, employment status and number of children. Conclusion: The research reveals convergences between the thinking of the Church´s leaders and the practice of pastoral agents related to family planning, but also demonstrates tensions and difficulties.Este artigo se situa no contexto do planejamento familiar com o objetivo principal de identificar o quanto agentes de pastoral de uma comunidade cristã acolheram a gravidez do primeiro fi lho. Método: Este trabalho é fruto de uma pesquisa bibliográfica e de campo realizada com 278 agentes de pastoral da Diocese de Jacarezinho, estado do Paraná, Sul do Brasil.

Resultado: Este artigo explora a resposta dos participantes da pesquisa à indagação: “Qual foi a sua reação ao anúncio da gravidez do primeiro filho?” De acordo com as possibilidades de respostas apresentadas, o resultado foi o seguinte: revolta 0,5%, preocupação 13,1%, surpresa 4,7%, aceitação 7,9% e alegria 64,8%. Esses dados foram cruzados e explorados na perspectiva de gênero, idade da primeira gravidez, estado civil, situação de empregabilidade e número de filhos. Conclusão: A pesquisa revela pontos de convergência entre o pensamento da liderança religiosa e a prática de agentes de pastoral relacionados com o planejamento familiar, mas também demonstra tensões e dificuldades

AVALIAÇÃO EXPERIMENTAL E NUMÉRICA DA CINÉTICA DO CONGELAMENTO DO MÚSCULO DE ABRÓTEA (Urophycis brasiliensis)

This work carried out an experimental and numerical study of the kinetics of freezing of the Brazilian codling (Urophycis brasiliensis) muscle in air blast freezer, with air temperature set at 253.15 K and the average convective heat transfer coefficient at 25.4 W m-2 K-1. The initial temperature of the fish muscle was 277.15 K and the final temperature 255.15 K. The objective of this work was verify the best agreement between the experimental temperature profile and the numerical temperature profile to Brazilian codling muscle, using the CFD (Computational Fluid Dynamics) as numerical tool. In relation to the obtained results, it was verified that a good agreement between the experimental and numerical temperature profiles for the Brazilian codling muscle. The experimental freezing time found was 6618 s, and the freezing time through the numerical simulation was 6246 s. The error percentage found was 5.6%.Este trabalho realizou um estudo experimental e numérico da cinética de congelamento do músculo de abrótea (Urophycis brasiliensis) em uma câmara fria de convecção a ar forçado, com a temperatura do ar fixada em 253,15 K e o coeficiente convectivo médio de transferência de calor de 25,4 W m-2 K-1. A temperatura inicial do músculo do pescado foi de 277,15 K e a temperatura final de 255,15 K. O objetivo deste trabalho foi verificar a melhor concordância entre o perfil de temperatura experimental e o perfil de temperatura numérico para o músculo de abrótea, utilizando o CFD (Computational Fluid Dynamics) como ferramenta numérica. Em relação aos resultados obtidos, verificou-se uma boa concordância entre os perfis experimentais e numéricos de temperatura para o músculo de abrótea. O tempo de congelamento experimental encontrado foi de 6618 s, e o tempo de congelamento pela simulação numérica foi de 6246 s. O percentual de erro encontrado foi de 5,6%

Schwinger multichannel method: A study of a Feshbach resonance in e-H_2 collisions

We present results of the application of the Schwinger multichannel method to study the role of Feshbach resonances on the elastic and electronic excitation cross sections in e-H_2 collisions. Using a ^2Σ_g^+2 resonance associated with the a ^3Σ^+_g and E^1Σ^+_g states of H_2 as an example, we quantitatively illustrate the dramatic influence of open channels on the decay of such Feshbach resonances in electron-molecule collisions

Growth, oil and protein yield of Jatropha curcas L. populations

Jatropha curcas L. is an oilseed with multiple applications, especially the pharmaceutical-industrial one. Cultivation is still very low due to the lack of commercial varieties, therefore, with the need to start the genetic improvement program and select superior genotypes, it is essential to know the genetic variability of the culture. Thus, the purpose of this study was to evaluate the vegetative growth, grain yield and oil and protein content in seeds populations of Jatropha curcas, to support the species breeding program. The experiment was carried out at the University Federal de Viçosa, State of Minas Gerais, Brazil, using a randomized complete block split-plot design with four replications and 4-plant plots, spaced at 2.5 m. Each plot consisted of clones of six populations coming from the towns of Janaúba (J1, J2, J3, J4 and J5) and Bonfim (B1), located in Minas Gerais. The 4.5-year-old populations were evaluated for plant height, stem diameter, leaf and fruit dry matter, grain yield and oil and protein content. The populations presented different plant heights (2.97 m), stem diameters (13.49 cm) and leaf dry matter (0.818 g) amounts. The J5 population showed taller plants (3.29 m) with longer stem diameter (15.34 cm). The greatest dry leaf weight (0.864 g leaf-1) was observed in the J2 population. The populations did not present genetic variability for fruit dry matter, grain yield and oil and protein content. Overall, the J5 population stood out with the highest levels of growth, grain yield and seed oil (31.7%) content

The isolation and characterization of endophytic microorganisms from Hyptis marrubioides Epling roots

Endophytic microorganisms asymptomatically colonize healthy plant tissues and may be related to the plant's resistance to attack by pathogens or even to the synthesis of secondary metabolites. The present study was aimed at isolating and characterizing endophytic strains from the root system of Hyptis marrubioides. Coarse and fine root fragments were collected for diaphanization and surface disinfection to isolate endophytes. After 10 days of incubation, we obtained the colonization rate (CR) of the fragments and the endophytic were purified and maintained in culture medium. The bacteria were partially characterized using Gram stain and a catalase test. Fungi were identified by distinguishing between reproductive structures using a microculture technique. While observing diaphanized root fragments, we found arbuscular mycorrhizal fungi (AMF) and dark septate endophytic (DSE) fungi in the fine and coarse roots of H. marrubioides. The endophytic CR was more significant in coarse root fragments. In both types of roots, the percentage of bacteria was higher than the percentage of fungi. Gram positive and catalase-positive bacteria accounted for the majority of bacterial isolates, which were predominantly bacilli. Of all the fungal isolates, the majority had sporulating mycelium, which mainly consisted of fungi from the genus Penicillium, Fusarium, Trichoderma and Papulaspora.Keywords: Bacteria, fungus, Lamiaceae, root syste
