No full textEnergy consumption and thermal comfort in university campus: a benchmarking proposal
No full textBenchmarking is a tool used for comparing energy consumption between a group of similar buildings or the same building over time. It is applicable for increasing transparency regarding energy management and the development of policies for energy efficiency. However, in buildings with predominance of natural ventilation, as Brazilian Public Universities, the EUI evaluation may not be sufficient to indicate the efficiency of the buildings in use, given that there is the possibility of occurrence of thermal discomfort. Therefore, the goal of this thesis is to develop an internal benchmarking system of university campus buildings based on electricity consumption and thermal comfort. The buildings of the Federal University of Minas Gerais, in Belo Horizonte, were used as a case study. EUI was considered as the metric for energy consumption analysis. The Percentage Occupied of Hours in Comfort (POHC) and the Degrees of Heat (DHH) were used as metrics related to thermal comfort. A EUI database of 110 buildings was built and focus was directed to 27 buildings of Academic Units, for which architectural characteristics were also raised. The thermal comfort of naturally ventilated classroom environments was analyzed from the development of archetypes and parametric computer simulations of 55 thousand scenarios with the EnergyPlus software. The method of this work, of interdisciplinary character, included the elaboration of four predictive equations via multiple regression models: two equations for the prediction of EUI and two related to thermal comfort, being one for POHC and one for DHH. The equations for EUI were divided for buildings with or without laboratories with high density of installed power. The thermal comfort equations consider the classrooms. A benchmarking was proposed with the classification of buildings on the scale from A to E both for EUI and for thermal comfort. The benchmarking classification was integrated by a matrix which generated classifications in levels “Good”, “Medium”, “Poor” and “Very poor”. The developed equations presented R² from 0.93 to 0.97. It was found that 29% of the analyzed buildings are in the diagnostic zone "Good", 53% in "Medium" and 18% in "Poor". No Academic Unit was classified as “Very poor”. It is expected that this diagnosis can be used to support the prioritization of retrofit measures. Author considers that for buildings of hybrid conditioning or with natural ventilation it is essential to include the indication of thermal comfort in a benchmarking process. The contextualization of the case study suggests that the methodology developed can be replicated in other public universities in the country.O benchmarking é uma ferramenta para comparação de consumo energético entre edifícios similares ou o mesmo edifício ao longo do tempo, sendo útil para o aumento de transparência quanto à gestão de energia e ao desenvolvimento de políticas para a eficiência energética. A métrica mais utilizada em benchmarkings energéticos é a Energy Use Intensity (EUI). No entanto, em edificações onde o condicionamento do ar é feito predominantemente por ventilação natural, como nas Universidades Públicas Brasileiras, a avaliação do EUI pode não ser suficiente para indicar a eficiência das edificações em uso, dado que há possibilidade de ocorrência de situações de desconforto térmico. Portanto, o objetivo desta tese é desenvolver um sistema de benchmarking interno de edifícios de campi universitários baseado no consumo de energia elétrica e no conforto térmico. Foram utilizados como estudo de caso os edifícios da Universidade Federal de Minas Gerais, em Belo Horizonte. Como métrica para análise de energia considerou-se o EUI e, como métricas para o conforto térmico, utilizaram-se o Percentual de Horas Ocupadas em Conforto (PHOC) e ao Graus Hora de Calor (GHC). Uma base de dados referente ao EUI de 110 edificações dos campi foi construída e optou-se por focar nos edifícios de Unidades Acadêmicas (UA) (27 prédios), para os quais foram levantadas também suas características arquitetônicas. O conforto térmico dos ambientes de salas de aula naturalmente ventiladas foi analisado a partir do desenvolvimento de arquétipos e simulações computacionais paramétricas de 55 mil cenários, com o software EnergyPlus. O método deste trabalho, de caráter interdisciplinar, incluiu a elaboração de quatro equações preditivas via modelos de regressão múltipla: duas equações referentes à energia para predição de EUI e duas referentes ao conforto térmico para predição de PHOC e GHC. As equações de EUI foram separadas para edifícios com e sem laboratórios de equipamentos densos. As equações de conforto térmico são referentes a salas de aula. Foi proposto um benchmarking com classificação dos prédios na escala de A a E tanto para EUI quanto para conforto térmico, integrados em uma matriz que gera classificações finais de níveis “bom”, “médio”, “ruim” e “muito ruim”. As equações desenvolvidas apresentaram R² de 0,93 a 0,97. Analisadas as UAs da UFMG, verificou-se que 29% apresentaram diagnóstico “Bom”, 53% “Médio” e 18% “Ruim”. Nenhuma UA foi classificada como “Muito ruim”. Espera-se que esse diagnóstico possa ser utilizado para embasar a priorização de medidas de retrofit. Acredita-se, que, para prédios em condicionamento híbrido ou com ventilação natural seja essencial a inclusão da indicação de conforto térmico em um processo de benchmarking energético. A contextualização do estudo de caso sugere que a metodologia desenvolvida pode ser replicada para outras universidades públicas do país.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superio
Multidrug resistant Pseudomonas aeruginosa survey in a stream receiving effluents from ineffective wastewater hospital plants
No full textBackground: Multi-drug resistant forms of Pseudomonas aeruginosa (MDRPA) are a major source of nosocomial infections and when discharged into streams and rivers from hospital wastewater treatment plants (HWWTP) they are known to be able to persist for extended periods. In the city of Manaus (Western Brazilian Amazon), the effluent of three HWWTPs feed into the urban Mindu stream which crosses the city from its rainforest source before draining into the Rio Negro. The stream is routinely used by Manaus residents for bathing and cleaning (of clothes as well as domestic utensils) and, during periods of flooding, can contaminate wells used for drinking water. Results: 16S rRNA metagenomic sequence analysis of 293 cloned PCR fragments, detected an abundance of Pseudomonas aeruginosa (P. aeruginosa) at the stream's Rio Negro drainage site, but failed to detect it at the stream's source. An array of antimicrobial resistance profiles and resistance to all 14 tested antimicrobials was detected among P. aeruginosa cultures prepared from wastewater samples taken from water entering and being discharged from a Manaus HWWTP. Just one P. aeruginosa antimicrobial resistance profile, however, was detected from cultures made from Mindu stream isolates. Comparisons made between P. aeruginosa isolates' genomic DNA restriction enzyme digest fingerprints, failed to determine if any of the P. aeruginosa found in the Mindu stream were of HWWTP origin, but suggested that Mindu stream P. aeruginosa are from diverse origins. Culturing experiments also showed that P. aeruginosa biofilm formation and the extent of biofilm formation produced were both significantly higher in multi drug resistant forms of P. aeruginosa. Conclusions: Our results show that a diverse range of MDRPA are being discharged in an urban stream from a HWWTP in Manaus and that P. aeruginosa strains with ampicillin and amikacin can persist well within it. © 2016 The Author(s)
How "Chicagoan" are Gary Becker's Economic Models of Marriage?
No full textThis paper describes Gary Becker’s theoretical models of marriage. At the micro-level, these are all rational choice models. At the market level, Becker offers two major types of models: partial equilibrium models based on Price Theory as taught by Marshall and Friedman and optimal sorting models based on optimal assignment models. The paper examines some of the possible intellectual influences on Becker’s theory of marriage, compares Becker’s research on marriage with that of some scholars interested in intra-marriage distribution, and documents that Becker’s students at Chicago were more interested in Becker’s Friedmanian models of marriage than in his optimal assignment models.
O contestado na moldura do Juazeiro: uma teoria da tradição em romance acidental
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2012Aqui se trata de evocar a palavra sertaneja, exposta no milagre dos ex-votos, no taco da umburana, no corpo brincante em movimento, trazendo a diversidade dos tempos conflagrados na memória artesanal, tecida de lembrança e esquecimento. Os eventos do Contestado, de Canudos e Juazeiro do Norte estão permeados pela oralidade dos folhetos, dos martelos improvisados, dos autos performáticos que são palimpsestos da cultura, periférica, feita de contatos, híbrida, contemporânea, singular e plural. (Agamben; Bhabha; Benjamin; Canclini; Nancy; Said; Zumthor).Abstract : This study focuses on analyzing the culture of people who are from the countryside of Brazil, as well as their literature and regionalism. In this respect, it presents the miracle of the ex-vows, bringing the diversity of the decades that are represented in a #handmade memory#, with its memories and oblivions. Events like Contestado, Canudos and Juazeiro do Norte are full of oral traditions which are presented in the literature and in the performances that are shown in the #autos#, which are as palimpsest of the peripheral culture, made by contact, hybrid, contemporary, singular and plural.

Transforming the Health Research Workforce in Mozambique: Achievements of the Mozambique Institute for Health Education and Research (MIHER) over a 13‑Year Journey.
No full textBackground: African research capacity is challenged by insufficient infrastructure to solicit and manage grants from local and international funding agencies. Objective: The manuscript provides an overview and discusses lessons learned about the pioneering role of the Mozambique Institute for Health Education and Research (MIHER) as the first research support center (RSC) in supporting the management of research grants in Mozambique, emphasizing its impact on research capacity development. Methods: Using mixed methods, data were comprehensively collected to identify MIHERs primary achievements from 2010 to 2023. The activities took place in four public universities, five training institutions for healthcare workers, and 40 public healthcare units in Mozambique. Findings: MIHER had partnership contracts with over 35 external institutions, and supported the design and implementation of one doctoral program and five masters degree programs at three public universities. Over 70% of the 128 MSc and three Ph.D. degree recipients have gone on to become lecturers at Mozambiques public universities or are working in Mozambiques public health system. Over 9,000 lecturers and healthcare workers participated in MIHERs 261 research capacity development workshops. MIHER assisted in writing and implementing 98 research grants, amassing $29,923,197 in extramural support. Of 170 publications generated, 89% were indexed in PubMed. African researchers served as first or last author in 55% and 34% of these publications, respectively; Mozambicans were first and last authors in 44% and 23% of the articles, respectively. Two research laboratories were rehabilitated. Investments in information and communication technology also fostered training and mentorship. Conclusions: MIHER has emerged as a leading RSC of Excellence, fostering synergies and promoting a quality research culture in Mozambique, fueled in part, by its ability to identify and incorporate key collaborations. MIHER is a successful example of an RSC that can make the difference in resource‑limited settings to enable research resource mobilization, evidence-based health care delivery and policy design
Corpo e educação: as relações interculturais nas práticas corporais bororo em Meruri-MT
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências da Educação. Programa de Pós-Graduação em Educação.Este estudo expressa o resultado de uma pesquisa com foco de interesse na "Educação do Corpo" (educação expressa nas práticas corporais) em contextos interculturais. Partindo das relações interculturais proporcionadas pela formação de professores indígenas em Mato Grosso # Projeto Tucum, esta pesquisa apoiou-se nos referenciais da Antropologia, da História e da Educação para compreender o contexto das relações estabelecidas na atualidade, entre os Bororo e a sociedade regional e entre eles e os missionários salesianos, com os quais convivem há mais de um século no Território Indígena de Meruri-MT. A pesquisa de campo foi realizada no período de maio a setembro de 2001, na Aldeia de Meruri, numa perspectiva etnográfica, cujo enfoque foram as práticas corporais cotidianas. Durante nossa observação participante, identificamos que as festas realizadas pela Missão eram apropriadas pelos Bororo e adquiriam um caráter polissêmico. Entre os múltiplos sentidos e significações cabe destacar a revitalização das formas tradicionais de "fabricação da pessoa", a valorização das identidades individual e coletiva e a criação de estratégias de integração. Os dados apontaram que a "Festa dos 25 Anos" potencializou processos educativos importantes que resultaram no Ritual de Nominação, nas Danças apresentadas na Missa de Ação de Graças realizada dia 15 de Julho de 2001, e nos jogos de Futebol. Essas três manifestações da cultura corporal foram registradas e analisadas nesta pesquisa e nos indicam uma perspectiva de educação intercultural entre a cultura bororo e a cultura não índia. Nesse processo polissêmico as identidades se confrontam num "jogo" que se estabelece nas "fronteiras" do "nós" e do "eles", criando novas possibilidades de interação e de educação
Das memórias às veredas: Revista USP - letras, cenas e sons
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-graduação em LiteraturaEsta tese tenta configurar o espaço ocupado pela literatura na Revista USP, partindo da reflexão que ali se realiza sobre a arte produzida nos anos 80 e 90. As criações recentes da música popular, do teatro e do cinema são submetidas a um balanço enquanto a literatura não recebe o mesmo tipo de abordagem crítica. Investigar as motivações e desdobramentos de tal postura por parte da revista é a principal proposição desta pesquisa, que busca desenvolver a seguinte hipótese: um vasto conjunto de ensaios publicados na Revista USP compõe um mosaico, no qual a reflexão acerca da literatura brasileira se configura através da constituição de um eixo monumental, formado por Memórias póstumas de Brás Cubas, de Machado de Assis e Grande sertão: veredas, de João Guimarães Rosa. Estas duas obras sustentam e demarcam os limites do cânone proposto pela revista, que posiciona a obra de Guimarães Rosa como última baliza do ciclo criativo da literatura brasileira. Entretanto, é possível perceber algumas sombras que conturbam o desenho nítido do referido eixo. A primeira delas é Grande sertão: veredas enquanto texto neobarroco e a segunda é uma antologia de poesia brasileira publicada na revista Universidad de México. This thesis tries to configure the space occupied by literature in Revista USP magazine, starting from the reflection about the art produced in the 80's and 90's. The popular music, the theater and the movies are submitted to an evaluation of their recent creations while the literature does not receive the same kind of critical approach. Investigating motivations and consequences of this attitude is the main proposition of this research, which intends to develop the following hypothesis: a great amount of texts published in Revista USP composes a mosaic, in which the reflection about Brazilian literature configures itself through the constitution of a monumental axle, formed by Memórias póstumas de Brás Cubas, written by Machado de Assis and Grande sertão: veredas, by João Guimarães Rosa. These books mark and support the limits of the canon proposed by the magazine, which considers Guimarães Rosa's narrative as the last sign of creativity in Brazilian literature. Although, it's possible to perceive some shadows that disturb the clearness of this axle. The first one is Grande sertão: veredas seen as a "neobarroco" text, and the second is an anthology of Brazilian poetry published at Universidad de México magazine
Dois lados da moeda?: Versus, um jornal alternativo, e Cultura, uma revista do MEC (1976 - 1978)
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em LiteraturaEsta dissertação é uma leitura comparativa de dois periódicos: Cultura, revista publicada pelo MEC (Ministério da Educação e Cultura) entre 1971 e 1984, e Versus, jornal alternativo que circulou entre 1975 e 1979. O recorte proposto se deteve nos anos de 1976, 1977 e 1978, ou, números 20 a 30 de Cultura e 01 a 23 de Versus. A partir do que os periódicos entendiam pelo termo "cultura", foram detectadas não só diferenças, mas, também, semelhanças entre ambos. Ainda com relação ao significado e função atribuídos à cultura por Cultura e Versus, detectamos as diferenças de posicionamento internas (isto é, dentro das publicações). Ao final, percebe-se que a "cultura", tanto por parte do Estado, como por parte dos opositores ao regime militar, é relegada a um segundo plano, seja pela conjuntura econômica, no primeiro caso, seja pela conjuntura política, no segundo
Age And Origin Of The Neoproterozoic Brauna Kimberlites: Melt Generation Within The Metasomatized Base Of The São Francisco Craton, Brazil
No full textThe diamondiferous Brauna kimberlite field is situated in the northeast part of the São Francisco craton, Bahia State, Brazil, and ongoing exploration revealed three complex pipe-like bodies and nineteen dykes oriented along a N30W trend. Uranium-Pb perovskite age determinations of hypabyssal kimberlite material yielded a high-precision emplacement age of 642. ±. 6. Ma (2-sigma uncertainty). This age provides the first evidence for Neoproterozoic kimberlite magmatism in Brazil, and the Brauna kimberlites thus represent the oldest known primary source of diamonds in the São Francisco craton.Primary kimberlite mineralogy at Brauna comprises olivine, spinel, ilmenite, phlogopite, perovskite, apatite, as well as late-stage serpentine and carbonate. Furthermore, abundant olivine, Cr-diopside, and pyrope garnet xenocrysts are present. The most common xenoliths are wall-rock granodiorites, mantle eclogites and peridotites. The Brauna kimberlites do not fit into the classic subdivision of kimberlites and orangeites (formerly Group-II kimberlites) based on South African type occurrences. Their geochemical and isotopic signatures, with negative initial εNd values of -5.8 to -8.1 and variably enriched 87Sr/86Sr ratios (0.7045-0.7063), suggest that Brauna kimberlite magmas were derived from a mantle source region that was strongly metasomatized prior to kimberlite magmatism at ~642Ma. In particular, the incompatible element distribution suggests that Brauna kimberlite magmas originate from the metasomatized base of the São Francisco craton, with only minor input from the convecting upper mantle. The Brauna kimberlites mineralogically and geochemically resemble the slightly older "anomalous" mica kimberlites from Guaniamo in Venezuela (712±6Ma). This may suggest that both mica-rich kimberlite occurrences formed from similarly enriched subcratonic mantle lithosphere during Late Neoproterozoic extensional tectonics related to the breakup of the supercontinent Rodinia. © 2012 Elsevier B.V.3531935Araújo, A.L.N., Carlson, R.W., Gaspar, J.C., Bizzi, L.A., Petrology of kamafugites and kimberlites from the Alto Paranaíba Alkaline Province, Minas Gerais, Brazil (2001) Contributions to Mineralogy and Petrology, 142, pp. 163-177Barbosa, J.S.F., Sabaté, P., Archean and Paleoproterozoic crust of the São Francisco Craton, Bahia, Brazil: geodynamic features (2004) Precambrian Research, 133, pp. 1-27Bardet, M.G., Géologie du diamant (1977) Memoires Du BRGM, p. 177Beard, A.D., Downes, H., Hegner, E., Sablukov, S.M., Geochemistry and mineralogy of kimberlites from the Arkhangelsk Region, NW Russia: evidence for transitional kimberlite magma types (2000) Lithos, 51, pp. 47-73Becker, M., Le Roex, A.P., Geochemistry of South African on- and off craton, group I and group II kimberlites: petrogenesis and source region evolution (2006) Journal of Petrology, 47, pp. 673-703Becker, M., Le Roex, A.P., Geochemistry and petrogenesis of South African transitional kimberlites located on and off the Kaapvaal Craton (2007) South African Journal of Geology, 110, pp. 631-646Beyer, C., Berndt, J., Tappe, S., Klemme, S., Trace element partitioning between perovskite and kimberlite to carbonatite melt: New experimental constraints (2013) Chemical Geology, 353, pp. 133-140. , (this issue)Bizzi, L.A., Smith, C.R., Meyer, H.O.A., Armstrong, R., de Wit, M.J., Mesozoic kimberlites and related rocks in southwestern São Francisco craton, Brazil: a case for local mantle reservoirs and their interaction (1993) Special Publication 2/91, pp. 156-171. , H.O.A.
