Evaluation of the coefficient of variation as a measure of precision to the experiments with citrus

O presente trabalho foi executado com dados de coeficientes de variação (CV) de vários trabalhos publicados no Brasil, com ênfase em citricultura, e suas variáveis mais correntemente estudadas (altura e produção de frutos por planta; diâmetro e peso dos frutos; rendimento, pH, "ratio", sólidos solúveis e acidez do suco). O objetivo foi o de propor faixas de CV que orientem o pesquisador na avaliação de cada variável. Após o agrupamento dos dados, procedeu-se ao teste de normalidade de Lilliefors, revelando que todas as variáveis utilizadas tiveram distribuição aproximadamente normal. Com isso, através de tabela sugerida para trabalhos com espécies florestais que relaciona a média e o desvio padrão [CV±√Var(CV)], foi construída uma tabela como sugestão de intervalo de CV, referente a cada variável em questão. A variável número de frutos por planta foi a que apresentou maiores valores do coeficiente, e as variáveis relacionadas ao suco (obtidas em laboratório), de forma geral, foram as que apresentaram menores CV.The present study was developed with values of coefficients of variation (CV) taken from various works published in Brazil, with emphasis on fruit culture, and their variables most currently studied (height and fruit production per plant; diameter and fruit weight; yield, pH, "ratio", soluble solids and juice acidity). The objective was to propose CV bands which orient the researcher in the evaluation of each variable. After data grouping, a test of normality of Lilliefors was made, which revealed that all the variables utilized had an approximately normal distribution. With this, by means of a table based on work with forest species which establishes the medium and the standard deviation [CV±√Var(CV)], a table was constructed with suggested intervals of CV for each variable in question. The number of fruits per plant variable was that which presented larger coefficient values, and the values related to the juice (obtained in the laboratory) were those which generally presented the smaller CV

Quadrinhos em aulas de português para estrangeiros: ensinando língua e cultura

Addresses the use of comics as didactic material for the teaching of Brazilian Portuguese for foreigners. The conception of comics as a window display of a target-culture (VERGUEIRO; RAMOS, 2009) is the starting point to discuss the possibilities of using them as facilitators to the development of linguistic-communicative and intercultural competences, required to foreign students by the current society. The article selects the “apologies” as Speech Acts (AUSTIN, 1967; GOMES, 2010) as example and suggests didactic strategies for the use of comics, taken as pedagogic tools to teach linguisticinteractional and communicative patterns in classes of Portuguese for foreign students. Partial results indicate students’ improvement in terms of making linguistic choices during interactional situations.Aborda a questão do uso de histórias em quadrinhos como material didático para o ensino de português do Brasil a estrangeiros. Parte da ideia dos quadrinhos como vitrine de uma cultura-alvo (VERGUEIRO; RAMOS, 2009), para discutir a possibilidade de usá-los como facilitadores do desenvolvimento de competências linguístico-comunicativas e interculturais, requisitadas ao aluno estrangeiro na sociedade atual. Selecionou-se o “pedido de desculpa” como ato de fala (AUSTIN, 1967; GOMES, 2010) para exemplificar e sugerir estratégias de uso de quadrinhos em aulas de português a estrangeiros, como ferramenta pedagógica para ensinar padrões linguístico-interacionais e comunicativos. Os resultados parciais apontam para a melhoria de desempenho dos alunos quanto às suas escolhas linguísticas em situações interacionais

Application of the single-minute exchange of die system to the CNC sector of a shoe mold company

The aim of this work is to present a quantitative evaluation of the benefits of applying the Single-Minute Exchange of Die (SMED) implemented in a shoe mold company. Based on the application of this methodology, we noticed that real gains were obtained with very little financial investment. The improvements observed in the sector were the reduction of set-up time by 60%, with an average set-up time of approximately 7 min, and an increase in the productive capacity of the sector by around 3%. There was a reduction in the incidence of errors in the machined parts due to the standardization of the processes performed by the operators. Among the advantages presented with the new system are reduced material exchange time, reduced time spent fine-tuning, less chance of errors during exchanges, improved product quality, greater reliability with respect to reduction of dissociation stocks and the flexibilization of the production system

The experience of the municipalities of Minas Gerais State (Brazil) that implemented local environmental licensing

The objective of this study was to explore the experience of the municipalities of the state of Minas Gerais that implemented local environmental licensing. For this purpose, representatives of the state administration were interviewed, and an electronic questionnaire was sent to analysts of 121 municipalities that took up environmental licensing, from which 39 responses were obtained. The key drivers of local environmental licensing were concerns over licensing procedural delays by the state government and the need for administrative efficiency. Knowledge of local conditions and the proximity between the local government, communities and developers were identified as facilitators of licensing. Shortage of staff, precarious hiring processes, and lack of infrastructure were identified as the main barriers to local environmental licensing. The municipalities that have implemented local environmental licensing perceive planning, administrative capacity, competent technical and legal teams, and capacity-building as essential elements of an effective local environmental licensing system. The study concludes with suggestions of future research avenues.The objective of this study was to explore the experience of the municipalities of the state of Minas Gerais that implemented local environmental licensing.

Gerenciamento de Projetos: Comparativo Bibliométrico dos Anais de Congressos Brasileiros na Área de Administração e Engenharia de Produção

This paper examined the scientific production on the subject of Project Management from period 2004 to 2014. The unit of analysis is composed of articles published in the Brazilian annals of the Meeting of the National Association of Graduate Studies and Research in Administration (EnANPAD) and the Meeting of the National Production Engineering (ENEGEP) in the last 11 years. The results show that the theoretical focus is in the discussion of how the fundamentals of project management are used by practitioners, because of the sub-theme of greatest interest identified in this study was the ‘Application of Practices’, followed by the sub-theme ‘Tools and Techniques’. The paper also points out that the research agenda has Brazilian researchers regularly and frequently in the theme, which depict the project management function of typical and unique variables in Brazil. Depending on the most cited references in the articles analyzed, confirms the importance of the journals referenced in accordance with the classification CAPES WebQualis and presence in SCOPUS Journal Metrics database with the indices Impact per Publication (IPP) and SCImago Journal Rank (JRS). Finally, it appears that there is little interest in project management studies by Brazilian researchers.Este artigo analisou a produção científica no tema do Gerenciamento de Projetos no período de 2004 a 2014. A unidade de análise é constituída por artigos publicados nos anais do Encontro da Associação Nacional de Pós-graduação e Pesquisa em Administração (EnANPAD) e do Encontro Nacional de Engenharia de Produção (ENEGEP) nos últimos onze anos. Os resultados apontam que o foco teórico está na discussão de como os fundamentos do gerenciamento de projetos são utilizados pelos praticantes, pois o subtema de maior interesse identificado neste estudo foi a ‘Aplicação das Práticas’, seguido do subtema ‘Ferramentas e Técnicas’. O artigo também destaca que a agenda de pesquisa possui pesquisadores brasileiros regulares e frequentes na temática, os quais retratam o gerenciamento de projetos em função das variáveis típicas e exclusivas do Brasil.

Por fim, constata-se que existe pouco interesse nos estudos em gerenciamento de projetos pelos pesquisadores brasileiros

Aves de um fragmento de Mata Atlântica no alto Rio Doce, Minas Gerais: Colonização e extinção

It is presented a bird survey of a forest fragment at the upper Rio Doce valley carried out from April 2002 to November 2004. The region is within one of the most important Brazilian hot spot for biological conservation: the Atlantic Forest. The fragment is within 'Estação de Desenvolvimento Ambiental de Peti' (EPDA-Peti) under the premises of a hydroelectric power station run by the Minas Gerais Energetic Company. It holds 605 ha of a mosaic of secondary growth forest patches from different ages, characterised mainly by semi deciduous forest. Bird census were carried out through transect, mist-net captures, point counts and recording bird vocalizations. The present survey was compared to an unpublished survey performed in 1989 to find out possible extinctions and colonization. It was recorded 231 species, belonging to 57 families. This represents 33% of all 682 bird species recorded for the Atlantic forest biome of east Brazil. Thirty-three species are considered endemic to the Atlantic Forest and one is considered endemic to the Cerrado biome of central Brazil. Five species are threatened in the state of Minas Gerais and one species is globally threatened to extinction, the red-billed curassow Crax blumenbachii Spix, 1825 (Cracidae). It was found 35 species not reported before for the area. Also, 52 species went locally extinct from the fragment. The EPDA-Peti holds a significant number of the Atlantic Forest bird species, and long-term bird monitoring on such fragments will reveal important aspects for the understanding of colonization and extinction in the biome

Universal Screening of SARS-CoV-2 of Oncology Healthcare Workers — a Brazilian experience

The first confirmed case of coronavirus disease 2019 (COVID-19) in Brazil and Latin America was reported on February 26, 2020, in São Paulo. The outbreak of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has placed unprecedented strain on health-care services worldwide. Asymptomatic health-care workers (HCW) are a potential source of SARS-CoV-2 transmission, especially to immunocompromised Oncology patients. Screening of these HCWs may help contain transmission and isolate only those who require it. At Centro de Terapia Oncológica (CTO), an Oncology clinic in Petrópolis, RJ —Brazil, all HCWs were screened for SARS-CoV-2 in order to isolate those who were asymptomatic/symptomatic and positive for the virus. They were all tested through IgM/IgG rapid testing and those who had symptoms were also tested with nasopharyngeal swabs for reverse transcription polymerase chain reaction (RT-PCR) tests besides IgM/IgG reactivity. Amongst the 60 tested employees, 4 were positive for SARS-CoV-2 and were isolated. This method may be useful for health-care services to detect asymptomatic HCW and maintain workers’ and patients’ health, as transmission probability could be reduced while avoiding becoming short-staffed during this time of crisis

Hipertermia maligna en Brasil: análisis de la actividad del hotline en 2009

BACKGROUND AND OBJECTIVES: Malignant hyperthermia (MH) is a pharmacogenetic disease that causes abnormal hypermetabolic reaction to halogenated anesthetics and/or depolarizing muscle relaxants. In Brazil, there is a hotline telephone service for MH since 1991, available 24 hours a day in São Paulo. This article analyzes the activity of the Brazilian hotline service for MH in 2009. METHODS: Prospective analysis of all phone calls made to the Brazilian hotline service for MH from January to December 2009. RESULTS: Twenty-two phone calls were received: 21 from the South/Southeast region of Brazil and one from the North region. Fifteen calls were requests for general information about MH. Seven were about suspected MH acute episodes, two of which were not considered as MH. In five episodes compatible with MH, all patients received halogenated volatile anesthetics (2, isoflurane; 3, sevoflurane) and one also used succinylcholine; there were four men and one woman, with a mean age of 18 years (2-27). The problems described in the five MH episodes were tachycardia (5), increased expired carbon dioxide (4), hyperthermia (3), acidemia (1), rhabdomyolysis (1), and myoglobinuria (1). One patient received dantrolene. All five patients with MH episodes were follow-up in the intensive care unit and recovered without sequelae. Susceptibility to MH was later confirmed in two patients by in vitro muscle contracture test. CONCLUSIONS: The number of calls per year in the Brazilian hotline service for MH is still low. The characteristics of MH episode were similar to those reported in other countries. The knowledge of MH in Brazil needs to be increased.JUSTIFICATIVA Y OBJETIVOS: La Hipertermia Maligna (HM) es una enfermedad farmacogenética, con una reacción hipermetabólica anormal a los anestésicos halogenados y/o relajantes musculares despolarizantes. Desde 1991 existe un servicio hotline de atención telefónica para la HM en Brasil a disposición las 24 horas del día en São Paulo. Este artículo analiza la actividad del servicio brasileño de hotline para la HM en el 2009. MÉTODOS: Análisis prospectivo de todas las llamadas telefónicas realizadas al servicio brasileño de hotline para la HM, desde enero a diciembre de 2009. RESULTADOS: Se recibieron 22 llamadas; 21 provenientes del Sur y Sudeste de Brasil y una del Norte. Quince eran solicitudes de informaciones generales sobre la HM. Siete fueron sobre sospechas de crisis agudas de HM, de las cuales dos no fueron consideradas como HM. En las cinco crisis compatibles con la HM, todos los pacientes recibieron anestésicos inhalatorios halogenados (2 isoflurano, 3 sevoflurano) y uno también usó succinilcolina. Había cuatro hombres y una mujer, con un promedio de edad de 18 años (2-27). Los problemas descritos en las cinco crisis de HM: taquicardia (cinco), aumento del gas carbónico espirado (cuatro), hipertermia (tres), acidemia (uno), rabdomiólisis (uno) y mioglobinuria (uno). Un paciente recibió dantrolene. Todos los cinco pacientes con crisis de HM recibieron acompañamiento en la unidad de cuidados intensivos y se recuperaron sin secuelas. La susceptibilidad a la HM fue posteriormente confirmada en dos pacientes por medio del test de la contractura muscular in vitro. CONCLUSIONES: El número de llamadas por año al servicio brasileño de hotline para la HM todavía es pequeño. Las características de las crisis fueron similares a las descritas en otros países. Es necesario aumentar el conocimiento que se tiene sobre la HM en Brasil.JUSTIFICATIVA E OBJETIVOS: Hipertermia maligna (HM) é doença farmacogenética, com reação hipermetabólica anormal a anestésicos halogenados e/ou relaxantes musculares despolarizantes.

Este artigo analisa a atividade do serviço brasileiro de hotline para HM em 2009. MÉTODOS: Análise prospectiva de todas chamadas telefônicas paria maligna (HM) é doença farmacogenética, com reação hipermetabólica anormal a anestésicos halogenados e/ou relaxantes musculares despolarizantes. Desde 1991 há um serviço hotline de atendimento telefônico para HM no Brasil, disponível 24 horas por dia, em São Paulo. Este art go analisa a at vidade do serviço brasileiro de hotline para HM em 2009a o serviço brasileiro de hotline para HM, de janeiro a dezembro de 2009. RESULTADOS: Foram recebidas 22 ligações; 21 provenientes do Sul-Sudeste do Brasil e uma do Norte. Quinze eram pedidos de informações gerais sobre HM. Sete foram suspeitas de crises agudas de HM, das quais duas não foram consideradas como HM. Nas cinco crises compatíveis com HM, todos os pacientes receberam anestésicos inalatórios halogenados (2 isoflurano, 3 sevoflurano) e um usou também succinilcolina; havia quatro homens e uma mulher, com média de idade de 18 anos (2-27). Problemas descritos nas cinco crises de HM: taquicardia (cinco), aumento do gás carbônico expirado (quatro), hipertermia (três), acidemia (um), rabdomiólise (um) e mioglobinúria (um). Um paciente recebeu dantrolene. Todos os cinco pacientes com crises de HM foram seguidos em unidade de terapia intensiva e recuperaram-se sem sequelas. A suscetibilidade à HM foi posteriormente confirmada em dois pacientes por meio do teste de contratura muscular in vitro. CONCLUSÕES: O número de chamadas por ano no serviço brasileiro de hotline para HM ainda é reduzido. As características das crises foram similares às descritas em outros países. É preciso aumentar o conhecimento sobre HM no Brasil.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUniversidade Federal de São Paulo (UNIFESP), Escola Paulista de Medicina (EPM) Setor de Doenças NeuromuscularesUNIFESP, EPM, Setor de Doenças NeuromuscularesSciEL
