Ecologia alimentar e reprodutiva da piaba-do-rabo-amarelo, Astyanax cf. lacustris (Reinhardt, 1874) (Osteichthyes: Characidae) na Lagoa do Piató, Assu, Rio Grande do Norte, Brasil

The feeding habits and biological aspects of the reproductive cycle of two-spot astyanax, Astyanax cf. lacustris (Reinhardt, 1874) were investigated. Fish samples were captured on a monthly basis, using gillnets of 4 cm mesh size, from the Piató Lake, Assu, Rio Grande do Norte, during the period of September, 2006 to August, 2007. Physico-chemical parameters, such as, temperature, electrical conductivity and dissolved oxygen of the lake were registered. The monthly values of rainfall also were obtained. The 360 individuals captured, were measured, weighed, dissected, and stomach weight and the stage of gonadal maturity were registered. The stomach contents analyses were carried out based on volumetric method, points, frequency of occurrence and applying the Index of Relative Importance. The degrees of repletion of the stomachs were determined besides the Index of Repletion relating to feeding activity variations and frequency of ingestion with limnological parameters and rainfall. The food items identified were separated into distinct groups according to their origin. Sex ratio and Gonadosomatic Relation of females were verified to determine the spawning period and fecundity. The physico-chemical parameters presented the following annual mean values: temperature = 28.8ºC, electrical conductivity = 992.5 µS.cm-1; dissolved oxygen = 4.9 mg.L-1 during the study period. The annual mean of the rainfall was 63.5 mm. The results indicate that this species present an omnivorous feeding habit with a tendency towards insectivory, with an increase in feeding activity during the dry season. The aquatic oxygen to interfere very importance in the feeding activity than the others factors physico-chemicals of water and rainfall. There was a predominance of females, with a sex proportion of 1M:7F. The macroscopic characteristics of the ovaries and testicles revealed four stages of gonadal development: immature, maturing, mature and spent. A temporal variation was observed for the gonadal development of males and females. There was reproductive activity through out the year, with peaks in the months of February, April and June to correspond with the rain of precipitation of the region. The mean fecundity was 7.681 mature oocytes, varying from 4.476 to 12.036, with mean of 7.681. There was positive relation between fecundity and body mass. Condition Factor is not an efficient indicator of the reproductive period of this species. The species A. cf. lacustris is an opportunist and is well adapted to the conditions of the semi-arid Caatinga Biome

Caracterização da captura incidental de tartarugas marinhas pela pesca de espinhel pelágico no Nordeste do Brasil

The marine turtles biological characteristics and the impact they have been suffering in consequence of human activities have caused in the last decades the decrease of populations to unsustainable levels. All four of the species described in this paper are registered as endangered in a list by IUCN: Caretta caretta, Lepidochelys olivacea, Chelonia mydas, Dermochelys coriacea. The main causes of such impact include several fishing activities, mostly the surface longline. This paper discusses the monitoring of two foreigner longline fleet along the North East Brazilian coast between October of 2004 and September of 2005. Both operated in the West South Atlantic, one using the Chinese technique and the other the American. The American method s target species is the swordfish (Xiphias gladius), and it is characterized by using squid as bait, J 9/0 offset 5º hook, light sticks and night soaking. It also operates in shallower waters than the Chinese method. The source of information about the efforts and the catches came from onboard observers and were used to calculate the catching rate of turtles over 1000 hooks (CPUE). The American equipment caught more turtles (CPUE = 0,059; N= 103), mainly D. coriacea, while the Chinese longline caught mainly the L. olivacea and presented a CPUE= 0,018 (N= 89). The hooks were most frequently found attached to the mouth of C. caretta, C. mydas, and L. olivacea. The D. coriacea were most frequently caught by hooks externally attached to different parts of their body. There was no significant difference between the hook type catching and most turtles were still alive when released. The results suggest a greater potential of turtle catching by the American method. Besides the statistic tests have showed less interaction between the Chinese equipment and marine turtles, the catches of this fishing technique could have been underestimated due to miscommunication between the onboard observer and the vessel s crew plus the retrieve of the longline during night time

Estudo de massa cerâmica triaxial visando à otimização do ciclo de queima da indústria de cerâmica estrutural

Over recent years the structural ceramics industry in Brazil has found a very favorable market for growth. However, difficulties related to productivity and product quality are partially inhibiting this possible growth. An alternative for trying to solve these problems and, thus, provide the pottery industry the feasibility of full development, is the substitution of firewood used in the burning process by natural gas. In order to contribute to this process of technological innovation, this paper studies the effect of co-use of ceramic phyllite and kaolin waste on the properties of a clay matrix, verifying the possible benefits that these raw materials can give to the final product, as well as the possibility of such materials to reduce the heat load necessary to obtain products with equal or superior quality. The study was divided into two steps: characterization of materials and study of formulations. Two clays, a phyllite and a residue of kaolin were characterized by the following techniques: laser granulometry, plasticity index by Atterberg limits, X-ray fluorescence, X-ray diffraction, mineralogical composition by Rietveld, thermogravimetric and differential thermal analysis. To study the formulations, specifically for evaluation of technological properties of the parts, was performed an experimental model that combined planning involving a mixture of three components (standard mass x phyllite x kaolin waste) and a 23 factorial design with central point associated with thermal processing parameters. The experiment was performed with restricted strip-plot randomization. In total, 13 compositional points were investigated within the following constraints: phyllite ≤ 20% by weight, kaolin waste ≤ 40% by weight, and standard mass ≥ 60% by weight. The thermal parameters were used at the following levels: 750 and 950 °C to the firing temperature, 5 and 15 °C/min at the heating rate, 15 and 45min to the baseline. The results showed that the introduction of phyllite and/or kaolin waste in ceramic body produced a number of benefits in properties of the final product, such as: decreased absorption of water, apparent porosity and linear retraction at burn; besides the increase in apparent specific mass and mechanical properties of parts. The best results were obtained in the compositional points where the sum of the levels of kaolin waste and phyllite was maximal (40% by weight), as well as conditions which were used in firing temperatures of 950 °C. Regarding the prospect of savings in heat energy required to form the desired microstructure, the phyllite and the residue of kaolin, for having small particle sizes and constitutions mineralogical phases with the presence of fluxes, contributed to the optimization of the firing cycle.

Adição de subprodutos da cinza da casca de café (coffea canephora) em massa cerâmica para porcelanato

To produce porcelain tiles fluxing agents are used in order to obtain a liquid phase during firing. This liquid phase fills the pores decreasing porosity, water absorption and contributes to material densification. In the porcelain tiles industry, feldspar is the main flux material used, with quantities ranging between 35 and 50%. Studies focus on the discovery of materials with flux characteristics that can reduce the consumption of feldspar by porcelain tiles industry. In this context, the coffee husk ashes, a residue obtained when coffee husks are burned to produce heat for the dryers during the processing of the green fruit, have as main chemical constituents potassium, calcium and magnesium, giving them characteristics of fluxing material. Brazil is the largest coffee producer in the world and is responsible for over 30% of the world s production. In this work a physical treatment of coffee husk ash was carried out in order to eliminate the organic matter and, after this, two by-products were obtained: residual wastes R1 and R2. Both residues were added separately as single fluxes and also in association with feldspar in mixtures with raw materials collected in a porcelain industry located in Dias d Ávila-Ba. The addition of these residues aimed to contribute to the reduction of the consumption of feldspar in the production of porcelain tiles. Specimens were produced with dimensions of 60 mm x 20 mm x 6 mm in an uniaxial die with compacting pressure of 45 MPa. The samples were heated to a temperature of 1200 °C, for 8 minutes. Tests were performed to characterize the raw materials by XRF, XRD, particle size analysis, DTA and TGA and, additionally, the results of the physical properties of water absorption, apparent porosity, linear shrinkage, density, dilatometry, flexural strength and SEM of sintered body were analyzed. Additions of less than 8% of the residue R1 contributed to the decrease of porosity, but the mechanical strength of the samples was not satisfactory. Additions of 5% the R2 residue contributed significantly to decrease the water absorption and apparent porosity, and also to increase the mechanical strength. Samples with addition of feldspar associated with the R2 residue, in proportions of 6.7% of R2 and 6.7% of feldspar, led to results of water absorption of 0.12% and mechanical strength of 46 MPa, having parameters normalized to the manufacture of porcelain stoneware tiles

Atividade antiplasmódica e toxicológica de plantas medicinais usadas popularmente no Brasil : uma abordagem etnobotânica

Malaria is a disease of global distribution, recognized by governments around the world as a serious public health problem, affecting more than 109 countries and territories and endangering more than 3.3 billion people. The economic costs of this disease are also relevant: the African continent itself has malaria-related costs of about $ 12 billion annually. Nowadays, in addition to chloroquine, Plasmodium falciparum is resistant to many drugs used in the treatment of malaria, such as amodiaquine, mefloquine, quinine and sulfadoxine-pyrimethamine; resistance of Plasmodium vivax to treatments, although less studied, is also reported. Nature, in general, is responsible for the production of most known organic substances, and the plant kingdom is responsible for the most of the chemical diversity known and reported in the literature. Most medicinal plants commercialized in Brazil, however, are of exotic origin, which makes the search for endemic medicinal plants, besides a patent necessity, a fascinating subject of academic research and development. This study aimed to: (i) verify the antimalarial activity of ethanolic and hydroalcoholic extracts of Boerhavia paniculata Rich. And acetonic extract of Clethra scabra Pers. in Swiss albino mice infected by Plasmodium berghei NK65, (ii) observe possible combined effects between the course of infection by P. berghei NK65 and administration of these extracts in Swiss albino mice, and (iii) conduct a preliminary study of the acute toxicity of these extracts in Swiss albino mice. All extracts notable pharmacological activities - with parasite infections inhibitions ranging from 22% to 54%.These characteristics suggest that the activities are relevant, although comparatively lower than the activity displayed by the positive control group (always above 90%). The general framework of survival analysis demonstrates an overall reduction in survival times for all groups. Necroscopy has not pointed no change in color, shape, size and/or consistency in the evaluated organs - the only exception was the livers of rats submitted to treatment to hydroalcoholic extracts: these organs have been presented in a slightly congestive aspect with mass increasing roughly 28% higher than the other two groups and a p-value of 0.0365. The 250 mg/Kg ethanolic group has been pointed out by the Dunn s post test, as the only class with simultaneous inequalities (p<0.05) between positive and negative control groups. The extracts, notably ethanol extract, have, in fact, a vestigial antimalarial activity, although well below from the ones perceived to chloroquine-treated groups; nevertheless, the survival times of the animals fed with the extracts do not rise by presence of such therapy. Both the toxicopharmacological studies of the synergism between the clinical course of malaria and administration of extracts and the isolated evaluation of toxicity allow us to affirm the absence of toxicity of the extracts at the level of CNS and ANS, as well as their non-influence on food and water consumption patterns, until dosages of 500 mg/Kg. Necroscopic analysis leads us to deduct a possible hepatotoxic effect of hydroalcoholic extract at dosages of 500 mg/Kg, and an innocuous tissue activity of the ethanol extract, in the same dosage. We propose a continuation of the studies of these extracts, with protocol modifications capable of addressing more clearly and objectively their pharmacological and toxicological aspects

Análise do estado da arte dos aspectos diagnóticos, periciais e jurisprudenciais das LER/DORT no contexto previdenciário das doenças do trabalho no Brasil

Objetivo: analisar o estado da arte dos aspectos diagnósticos, periciais e jurisprudenciais das LER/DORT (Lesões por Esforços Repetitivos / Distúrbios Osteomusculares Relacionados ao Trabalho) no Brasil. Materiais e Método: trata-se de pesquisa descritiva, de natureza qualitativa, com formato documental, utilizando-se a técnica de análise de conteúdo. A avaliação evolutiva da legislação previdenciária relacionada as LER/DORT foi realizada através da pesquisa no banco de dados disponibilizado pelo Governo Federal e mediante a consulta ao DATAPREV/Sislex. A avaliação dos aspectos diagnósticos foi instrumentalizada através, principalmente, de artigos científicos publicados entre 2003 e 2008, nas línguas portuguesa, inglesa, espanhola e francesa, relacionados com os métodos de diagnósticos complementares das LER-DORT (ressonância magnética, tomografia computadorizada, ultrassonografia e eletroneuromiografia). As jurisprudências foram obtidas através da busca dos julgados sobre o tema, entre 2003 e 2008, pertencentes ao Supremo Tribunal Federal, Superior Tribunal de Justiça, Tribunais Regionais Federais, Tribunal Superior do Trabalho e Tribunais Regionais do Trabalho. Resultados: foram identificados 48 artigos abordando os aspectos diagnósticos das LER-DORT, observando-se que os exames por ressonância magnética, ultrassonografia e eletromiografia demonstraram ser mais efetivos, dentro das suas especificidades, para a complementação do exame clínico de patologias relacionadas às LER-DORT. A análise das 123 jurisprudências selecionadas demonstrou, de forma geral, que as LER-DORT equiparam-se ao acidente de trabalho, devendo apresentar nexo de causalidade (atestado através de laudo médico-pericial) e, ainda, ensejam a ação por danos morais, a qual, devido à EC nº 45 passou a ser competência da Justiça do Trabalho. O Estado da arte dos aspectos periciais encontra-se representado pela vigência da Instrução Normativa n. 98/2003, a qual traz como aspecto fundamental a determinação de novos parâmetros a serem considerados na definição de um quadro de LER-DORT, dispondo, ainda, sobre a conduta ética que deve ser adotada pelo médico perito, bem como chama a atenção para a necessidade dessas doenças do trabalho serem comunicadas às autoridadades competentes, através da emissão da Comunicação de Acidente de Trabalho (CAT). Conclusão: as LER-DORT representam, hoje, um problema de importante impacto, não apenas previdenciário, mas também econômico em diversos países, nos quais o Brasil encontra-se inserido. Estudos sobre o estado da arte relacionados às LER-DORT são fundamentais para auxiliar na construção de um modelo crítico e consciente que colabore com a garantia de sustentabilidade do sistema previdenciário no Brasil

Acúmulo de massa seca e de macronutrientes por plantas de Glycine max e Solanum americanum

A soja é uma das principais culturas agrícolas do Brasil, sendo a sua produtividade muito influenciada pela competição exercida pelas plantas daninhas. Foram realizados dois experimentos em casa de vegetação, em Jaboticabal, SP, objetivando determinar o acúmulo de massa seca, assim como a distribuição e o acúmulo de macronutrientes em plantas de soja, no período de outubro de 2000 a fevereiro de 2001, e de Solanum americanum, no período de janeiro a maio de 1995. As plantas cresceram em vasos com capacidade de 7 litros, preenchidos com areia de rio lavada e peneirada; elas foram irrigadas diariamente com solução nutritiva. Os tratamentos foram representados pelas épocas de amostragem, realizada a intervalos de 14 dias, iniciando-se 21 dias após a emergência (DAE), até 161 DAE para S. americanum e 119 DAE para soja cv. BR-16 (precoce). O ponto de máximo acúmulo teórico de massa seca deu-se aos 104 DAE para a soja (35,0 g por planta) e 143 DAE para S. americanum (179,62 g por planta). da emergência até 49 e 63 DAE, as folhas apresentaram maior participação no acúmulo de massa seca para soja e S. americanum, respectivamente. Após esses períodos, verificou-se, em ambas as espécies, inversão na representatividade das folhas por caules para a espécie daninha e por caules e, posteriormente, por estruturas reprodutivas, para a cultura. A taxa de absorção diária dos macronutrientes atingiu maiores valores entre 69 e 87 DAE para a soja e entre 105 e 119 DAE para a planta daninha. Considerando a média dos valores de pontos de inflexão observados para a cultura da soja, tem-se que aos 75 DAE uma planta de soja acumula teoricamente 23,9 g de massa seca, 564,4 mg de N, 7,1 mg de P, 490,8 mg de K, 487,0 mg de Ca, 156,6 mg de Mg e 36,0 mg de S. Para o mesmo período, uma planta de S. americanum acumula teoricamente 33,75 g de massa seca, 875,96 mg de N, 88,46 mg de P, 983,54 mg de K, 647,60 mg de Ca, 100,93 mg de Mg e 42,15 mg de S.

Acúmulo de massa seca e macronutrientes por plantas de Glycine max e Richardia brasiliensis

Foram realizados dois experimentos, em condições de casa de vegetação, no Departamento de Biologia Aplicada à Agropecuária da FCAV-UNESP de Jaboticabal, objetivando-se determinar o acúmulo de massa seca, assim como a distribuição e o acúmulo de macronutrientes durante os ciclos de vida de plantas de soja cultivar BR16, no período de outubro de 2000 a fevereiro de 2001, e de Richardia brasiliensis (poaia-branca), uma planta daninha de elevada importância para esta cultura no Brasil, especialmente em áreas de plantio direto, no período de outubro de 1998 a fevereiro de 1999. Os estudos foram realizados em delineamento experimental inteiramente casualizado, com quatro repetições. Quatro plantas cresceram em vasos com capacidade de sete litros, preenchidos com areia de rio lavada, peneirada e irrigada diariamente com solução nutritiva. Os tratamentos foram representados pelas épocas de amostragem, realizadas a intervalos de 14 dias, a saber: 22, 36, 50, 64, 78, 92, 106, 120, 134, 148, 162 e 176 dias após a emergência (DAE) das plantas de R. brasiliensis; e 21, 35, 49, 63, 77, 91, 105 e 119 DAE das plantas de soja cv. BR-16 (precoce). em ambas as plantas, as folhas tiveram a maior partição de biomassa durante sete semanas. Para este dado, a partição foi maior para as estruturas reprodutivas em soja e nos caules para a poaia-branca. O ponto de máximo acúmulo teórico de massa seca deu-se aos 104 DAE para a soja (36,6 g por planta) e aos 146 DAE para a poaia-branca (16,4 g por planta). da emergência até aos 50 DAE as folhas apresentaram maior participação no acúmulo de massa seca, nas duas espécies. Após 50 DAE notou-se, em ambas as espécies, uma inversão na representatividade das folhas por caules, para a espécie daninha, e por caules e posteriormente por estruturas reprodutivas, para a cultura. A taxa de absorção diária dos macronutrientes atingiu maiores valores entre 69 e 87 DAE para a soja e entre 106 a 111 DAE para a planta daninha. Levando em conta a média dos valores de pontos de inflexão observados para a cultura da soja, aos 78 DAE uma planta de soja acumula teoricamente 25,9 g de massa seca; 615,5 mg de N; 77,2 mg de P; 538,6 mg de K; 535,0 mg de Ca; 171,5 mg de Mg; e 39,5 mg de S. Para o mesmo período, uma planta de R. brasiliensis acumula teoricamente 3,7 g de massa seca; 50,8 mg de N; 3,2 mg de P; 104,4 mg de K; 127,8 mg de Ca; 18,8 mg de Mg; e 3,7 mg de S.

A trajetória dos movimentos socioambientais em Sergipe : personagens, instituições e estratégias de comunicação

The research aimed to study the emergence, role, and the possibilities of environmental movements in Sergipe, running through an analysis of the period between 1983 and 2011. This goal has been guided by the core issue of research, which was to analyze the relationship between the mission, structure and action of environmental organizations in Sergipe. The research arose from the need to map and critically evaluate the environmental movement in Sergipe. The methodological procedures focused on the literature search, survey papers in Sergipe a time gap of 28 years, detailed analysis of nine "movements" and selected in-depth interviews, semi-structured interviews with dozens of social actors involved in the area. In conclusion, we observed that environmentalism in Sergipe, from its inception, was associated with recovery of consciousness regarding the environment, to combat local problems of degradation, and the search for legitimacy of public opinion. Although the environmental movement have been, at times, the attention of mass media, the movement failed to leave the niche and achieve a more representative portion of society. You can still see the deep relationship between the profile of environmental leaders, capital strength and the practical results of the environmental actions and finally, it was observed that the action of the movements has much stronger bond with the relationship of the organization and its main leaders with the other "environmentalist," than with the structure and mission of the institution

Vitrine das letras: o discurso jornalístico e a modernidade pedagógica em Sergipe/Brasil e Portugal - (1910-1920)

Dans cette étude, j'ai eu comme objectif d'établir les connexions et/ou les non-connexions dans les discours journalistiques sur la modernité pédagogique, dans les journaux O Correio de Aracaju (Le Courrier d'Aracaju, Sergipe, Brésil) et O Século (Le Siècle, Portugal), dans la période 1910-1920. J'ai tout particulièrement cherché le dit dans les journaux, dans le sens foucaldien du terme, en continu dialogue avec d'autres auteurs, dans une perspective interdisciplinaire. J'ai tenté de répondre à mon interrogation initiale : quelles sont les connexions et non connexions que l'on pourrait établir entre l'École Moderne du Portugal et celle de Sergipe, au Brésil, en prenant comme source d'analyse les discours journalistiques dans des journaux des deux pays ? Á partir de ce questionnement, à travers un abordage historico-comparatif interculturel, j'ai soutenu la THÈSE que les discours journalistiques du Século et du Correio de Aracaju, bien qu'ils relèvent de genres journalistiques différents quant au niveau de développement de la presse, ont traduit une perception et une assimilation de la modernité pédagogique articulées à une même epistémè. Ainsi, ces discours ont émergé comme objets métis, dont la création s'est faite dans des interlocutions, échanges, impositions et débats dans un processus continu de communication interculturelle. La nature messianique de ces discours, dans le système d'idées républicain, traduisait le sens de la modernité pédagogique prétendue et diffusée par les textes qui exprimaient l'aspiration de rupture et de progrès, tant au Portugal que dans l'état brésilien de Sergipe. Il a également été possible de faire des approximations/comparaisons entre la dispute (article d'opinion), dans le Correio de Aracaju et l'enquête (interview et reportage), dans O Século et de souligner ainsi les connexions et/ou non-connexions présentes sur le thème de la modernité pédagogique dans les discours journalistiques

Podcast na educação brasileira: natureza, potencialidades e implicações de uma tecnologia da comunicação

This thesis aims to build a panoramic analysis with the intention of providing the theoretical initial a thought articulated educational of podcast, a technology orality distributed demand. This joint search considering the various spheres that educational technology in Brazilian use, both in school and non-school contexts, including scenarios and distance. This study unites questions addressed piecemeal in the area to new perspectives about the podcast, in order to characterize its nature, examining such technology from a perspective of educational technology itself, as well as unveiling its main potentials and implications. The survey was conducted from the combined use of quantitative and qualitative categories, with emphasis on the last one. The method of participant observation was followed by immersion of the researcher in the audience groups of Brazilians podcasts. Data collection with sources held in non-school contexts, from a look at targeted interactions given the blogs of Brazilian productions, as well as from open-ended interviews with producers - made online - besides giving themselves from the hearing itself about five hundred podcasts of Brazil. In the school context, the research focused on a literature review of the literature of the study area. Were added to the corpus described statistics derived mainly from "Podpesquisa 2009," Numerical major survey on the use of podcasts in Brazil. The articulation and analysis of the collected data, we used the concept of Education Paulo Freire (1971, 1987), so that, understanding it as synonymous to communication - understood this concept in Freire - were able to reveal the various ramifications educational podcast Brazilian atmosphere permeated by a dialogic between its participants. Moreover, the ideas of Célestin Freinet (1998) about the cooperation, while education practice, conducted the analyzes productive technology addressed in this work. The philosophical thought of Andrew Feenberg (2003) on the notion of "technologies" buoyed technological design elaborate. Such consideration provided the foundation for the reflections and proposals offered in this study, which, in the characterization of the oral nature of the podcast - especially their version for the deaf - appropriated the placements Luis Antonio Marcuschi (2001) about the relationship between orality and writing. In addition to these references, several other authors were considered, dealing with issues that pervade the theme here delimited, contemplating discussions on topics such as educational interest, online production, inclusive education, among other aspects. At the end, there was the podcast as a technology, while still reproducing social asymmetries Brazilian fairly directed at promoting mitigations hierarchical and open production in digital orality promotes. In view of its technical and educational implications in national use, the technology study has revealed potential relevant to the sophistication of teaching practices with orality, in various contexts, and proved adequate to serve as a motto to the revision of school practices, to even the very role of the school. This, by the prospects unveiled here, can, through the podcast, mitigate their questions reproductivist to constitute themselves as under privileged communication, boosted by critical rescue and sophistication of management through the most basic education component: speech

Avaliação de economias de escala e escopo no desempenho de equipes de serviços aplicando Análise de Envoltória de Dados DEA: um estudo em Empresa de Telecomunicações no Brasil

This Master s Thesis proposes the application of Data Envelopment Analysis DEA to evaluate economies of scale and economies of scope in the performance of service teams involved with installation of data communication circuits, based on the study of a major telecommunication company in Brazil. Data was collected from the company s Operational Performance Division. Initial analysis of a data set, including nineteen installation teams, was performed considering input oriented methods. Subsequently, the need for restrictions on weights is analyzed using the Assurance Region method, checking for the existence of zero-valued weights. The resulting returns to scale are then verified. Further analyses using the Assurance Region Constant (AR-I-C) and Variable (AR-I-V) models verify the existence of variable, rather than constant, returns to scale. Therefore, all of the final comparisons use scores obtained through the AR-I-V model. In sequence, we verify if the system has economies of scope by analyzing the behavior of the scores in terms of individual or multiple outputs. Finally, conventional results, used by the company in study to evaluate team performance, are compared to those generated using the DEA methodology. The results presented here show that DEA is a useful methodology for assessing team performance and that it may contribute to improvements on the quality of the goal setting procedure.

Modelagem da transferência de massa na remoção do óleo da água produzida por flotação em coluna com uso de tensoativos de origem vegetal

The treatment of oil produced water and its implications are continually under investigation and several questions are related to this subject. In the Northeast Region Brazil, the onshore reservoirs are, in its majority, mature oil fields with high production of water. As this oil produced water has high levels of oil, it cannot be directly discarded into the environment because it represents a risk for contamination of soil, water, and groundwater, or even may cause harm to living bodies. Currently, polyelectrolytes that promote the coalescence of the oil droplets are used to remove the dispersed oil phase, enhancing the effectiveness of the flotation process. The non-biodegradability and high cost of polyelectrolytes are limiting factors for its application. On this context, it is necessary to develop studies for the search of more environmentally friendly products to apply in the flotation process. In this work it is proposed the modeling of the flotation process, in a glass column, using surfactants derived from vegetal oils to replace the polyelectrolytes, as well as to obtain a model that represents the experimental data. In addition, it was made a comparative study between the models described in the literature and the one developed in this research. The obtained results showed that the developed model presented high correlation coefficients when fitting the experimental data (R2 > 0.98), thus proving its efficiency in modeling the experimental data.
