If a woman has a big head : Physiognomy and female nature in an assyro-babylonian text
Couto Ferreira, érica
Asclepio : Revista de Historia de la Medicina y de la Ciencia , 2008,
Abstract: In Mesopotamia, the human body was understood as an object for divination, that is, a system of signs, which carried messages about the individual, and whose meaning had to be decoded by means of observation and interpretation. Taking the physiognomic series umma sinni tu qaqqada rabat ( If a woman has a big head ) as the main source of my article, I analyse, on the one hand, the processes that take part in the promotion of a particular perception of women based on a specific reading of the female body. On the other hand, I deal with the elements that characterize this female perception, basically, the image of the ideal woman centred on motherhood, and, in close relation to this, the dangers that threaten women’s life during pregnancy. El cuerpo humano en Mesopotamia era entendido como objeto adivinatorio: un sistema de signos, portador de mensajes sobre el propio individuo, cuyo significado debía decodificarse mediante la observación y la interpretación. Tomando como fuente principal de mi trabajo la serie fisionómica umma sinni tu qaqqada rabat ( Si una mujer tiene la cabeza grande ), analizo, por una parte, los mecanismos por los que se promueve una determinada visión de las mujeres en la adivinación fisionómica a partir de la lectura sexuada de su cuerpo. Por otra, los elementos que caracterizan esta imagen femenina, en base a dos grandes ejes: la imagen de la mujer ideal encarnada en el rol de madre; y los peligros que amenazan la vida de las mujeres en calidad de procreadoras.
Predicting of the Fibrous Filters Efficiency for the Removal Particles from Gas Stream by Artificial Neural Network  [PDF]
érica Regina Filletti, Juliana Maria da Silva, Valdemir Garcia Ferreira
Advances in Chemical Engineering and Science (ACES) , 2015, DOI: 10.4236/aces.2015.53033
Abstract: In this paper, artificial neural networks are used for predicting single fiber efficiency in the process of removing smaller particles from gas stream by fiber filters. For this, numerical simulations are obtained of a classic model of literature for fiber efficiency, which is numerically solved along with the convection diffusion equation in polar coordinates for particle concentration, with associated initial and boundary conditions. A sufficient number of examples from two numerical simulations are employed to construct a database, from which parameters of a novel neural model are adjusted. This model is constructed based on the back propagation algorithm in order to map two features, namely Peclet number and packing density, which are extracted from the numerical simulations into the corresponding single fiber efficiency. The results indicate that the developed neural model can be trained in a reasonable computational time and is capable of estimating single fiber efficiency from examples of the test set with a maximum error of 1.7%.

Abstract: in today's highly competitive scenario, the industrial and retail sectors seek alternatives to ensure their continuity in the brazilian market. to meet consumer expectations, one of the alternatives these sectors have devised is to offer a mix of products tailored to the profile of each group of customers. within this context, the category management (cm) tool and other efficient consumer response (ecr) practices have begun to take hold in the daily routine, culture and strategies of companies. to illustrate how the cm can be an efficiency-optimizing tool in supply chain management, this article discusses the main actions to be developed in the implementation of this tool in small and medium sized supermarkets, its facilitating and limiting characteristics, and criteria for the choice of business partners.
Free fields in skew fields

Mathematics , 2008,
Abstract: Building on the work of K. Chiba (J. Algebra 263 (2003), 75-87), we present sufficient conditions for the completion of a division ring with respect to the metric defined by a discrete valuation function to contain a free field, i.e. the universal field of fractions of a free associative algebra. Several applications to division rings generated by torsion-free nilpotent groups, skew Laurent series and related division rings are discussed.
Espiritualidade Umbandista: recriando espa os de inclus o (Umbanda Spirituality: recreating spaces of inclusion) - DOI: 10.5752/P.2175-5841.2013v11n29p29

Abstract: O artigo se prop e apresentar alguns elementos da cosmovis o umbandista para que possamos entender de que maneira esta legitima e ressignifica os espa os de inclus o social de parte da popula o brasileira. Esta cosmovis o recria e dá sentido às vidas e identidades das pessoas e, ao mesmo tempo, evidencia as exclus es sofridas ao longo das décadas. O texto busca uma compreens o dessas dinamicas antropológicas e sociológicas baseado em algumas teorias que se debru aram sobre a umbanda. Desde cedo afrodescendentes transitam entre universos simbólicos distintos e lan am m o de sua espiritualidade para reelaborarem suas tradi es criando possibilidades de jogar com papéis e identidades diversas. A Umbanda, por ser constitutivamente plural, é, muitas vezes, julgada por n o ter identidade própria. Por isso alguns elementos que comp em o arranjo da cosmovis o umbandista foram levantados na expectativa de apresentar um eixo compreensivo dessa identidade religiosa. Entretanto, faz-se necessário apontar tra os marcantes da Umbanda justamente para que seu caráter identitário n o fique à margem de outras denomina es religiosas afro-brasileiras. Palavras-chave: Umbanda. Espiritualidade. Inclus o Abstract This article presents some elements of Umbanda worldview to a better understanding of how this religion legitimizes and reframes the spaces of social inclusion of a portion of the Brazilian population. This worldview recreates and gives meaning to the lives and identities of people and at the same time, highlights the exclusions suffered by this people over the decades. Since their early years, Brazilian Afrodescendants move between different symbolic universes and use their spirituality to redesign their traditions, creating possibilities to play with different roles and identities. Umbanda, being constitutively plural, is often judged not to have its own identity. Thus, some elements that comprise Umbanda worldview were raised with the purpose of presenting an axis understanding of this religious identity. However, it is necessary to point out some relevant features of Umbanda, so that their identity features do not stay on the sidelines of other african Brazilian religious denominations.Finally, it seeks an understanding of these anthropological and sociological dynamics, based on some theoretical currents that investigate the Umbanda. Keywords: Umbanda. Spirituality. Inclusion.
Prey selection by two benthic fish species in a Mato Grosso stream, Rio de Janeiro, Brazil

Revista de Biología Tropical , 2011,
Abstract: Key to understand predator choice is the relationship between predator and prey abundance. There are few studies related to prey selection and availability. Such an approach is still current, because the ability to predict aspects of the diet in response to changes in prey availability is one of the major problems of trophic ecology. The general objective of this study was to evaluate prey selection by two species (Characidium cf. vidali and Pimelodella lateristriga) of the Mato Grosso stream, in Saquarema, Rio de Janeiro, Brazil. Benthos and fishes were collected in June, July and September of 2006 and January and February of 2007. Fish were collected with electric fishing techniques and benthos with a surber net. Densities of benthic organisms were expressed as the number of individuals per/m2. After sampling, the invertebrates were fixed in 90% ethanol, and, in the laboratory, were identified to the lowest taxonomical level. Approximately, seventy individuals from each species were selected randomly in each month. Fishes were fixed in 10% formalin in the field and transferred to 70o GL ethanol in the laboratory. Fishes had their stomachs removed for subsequent analysis. Fish diet was described according to the numeric frequency method. The Manly Electivity I ndex was applied in order to verify prey selection. The most abundant families in both benthos and diet of both fish species were the same, indicating that these species consume mainly most abundant prey in the environment. We concluded that prey selection occurs even for preys that had small abundance in the environment . However, it is the availability of the macroinvertebrate resources that determines the major composition of items in diet of fish, demonstrating that the abundance is the factor that most influences the choice of prey. Rev. Biol. Trop. 59 (4): 1697-1706. Epub 2011 December 01. Existen muy pocos estudios relacionados con la selección y disponibilidad de las presas por parte de sus depredadores. Actualmente, este enfoque se mantiene, debido a que uno de los principales problemas de la ecología trófica es la capacidad de predecir los aspectos de los hábitos alimentarios en respuesta a los cambios en la disponibilidad de las presas. El objetivo general de este estudio fue evaluar la seleccion de las presas en los especies (Characidium cf. vidali y Pimelodella lateristriga) del arroyo Mato Grosso en Saquarema, Rio de Janeiro. Se recolectaron bentos y peces en junio, Julio y septiembre 2006 y en enero y febrero 2007. Los peces fueron recolectados con técnicas de pesca eléctrica y los
Free fields in Malcev-Neumann series rings

Mathematics , 2011,
Abstract: It is shown that the skew field of Malcev-Neumann series of an ordered group frequently contains a free field of countable rank, i.e. the universal field of fractions of a free associative algebra of countable rank. This is an application of a criterion on embeddability of free fields on skew fields which are complete with respect to a valuation function, following K. Chiba. Other applications to skew Laurent series rings are discussed. Finally, embeddability questions on free fields of uncountable rank in Malcev-Neumann series rings are also considered.

International Journal of Molecular Sciences , 2012, DOI: 10.3390/ijms13078112
Abstract: Synthesis and spectral evaluation of new zinc and copper unsymmetrical mesoporphyrinic complexes are reported. Zn(II)-5-(4-acetoxy-3-methoxyphenyl)-10,15,20-tris -(4-carboxymethylphenyl)porphyrin, Zn(II)-5-[(3,4-methylenedioxy)phenyl]-10,15,20-tris -(4-carboxymethylphenyl)porphyrin, Cu(II)-5-(4-acetoxy-3-methoxyphenyl)-10,15,20-tris -(4-carboxymethylphenyl)porphyrin and Cu(II)-5-[(3,4-methylenedioxy)phenyl]-10,15,20-tris -(4-carboxymethylphenyl)porphyrin were synthesized using microwave-assisted synthesis. The complexes were characterized by elemental analysis, FT-IR, UV-Vis, EPR and NMR spectroscopy, which fully confirmed their structure. The spectral absorption properties of the porphyrinic complexes were studied in solvents with different polarities. Fluorescence emission and singlet oxygen formation quantum yields were evaluated for the compounds under study, revealing high yields for the zinc derivatives. The copper complexes are not emissive and only display residual capacity for singlet oxygen formation.

Abstract: A vegeta o natural junto aos corredores fluviais desempenha diversos papéis no controle e na qualidade ambiental de uma regi o, sendo uma das suas atribui es o estabelecimento de condi es adequadas de controle climático. Sem dúvida, cada estrutura de vegeta o ciliar deve apresentar um grau de eficiência para tal fun o. No entanto, quais s o as diferen as de respostas entre diferentes tipos de estrutura? Com o propósito de contribuir para uma resposta, este estudo discute as varia es microclimáticas a partir da avalia o das rela es existentes entre cinco variáveis climáticas em três diferentes perfis fision micos de vegeta o, (vegeta o arbórea densa, vegeta o arbórea rarefeita e campo) contíguos ao Ribeir o Cachoeira (Campinas, SP, Brasil). Dados de radia o solar, temperatura do ar e de globo, umidade relativa e velocidade do vento, além da temperatura da água, foram obtidos para cada perfil estudado, durante três dias, nos horários de maior insola o (das 8h às 16h), a três diferentes distancias do curso de água ao longo dos perfis, no ver o e no inverno. Como indicador do conforto térmico, foi calculada a Temperatura Fisiológica Equivalente (PET), para três horários, nas diferentes situa es estudadas. Os resultados evidenciaram a importancia da presen a e tipo de estrutura da vegeta o principalmente na atenua o da radia o solar e seu papel predominante no controle da temperatura e da umidade relativa do ar nas duas esta es do ano. A atenua o da radia o solar atingiu 97% em estrutura florestal e 83% em capoeiras; a umidade relativa variou, no ver o, de 85% a 100% na estrutura florestal, e entre 40% a 75% na estrutura campestre. Diferen as na temperatura ambiente de até 12,2 oC foram observadas entre a estrutura florestal e a estrutura campestre, no inverno. A ameniza o da temperatura da água em sistema florestado chegou a ser 3 oC em compara o à temperatura da água em sistema campestre. O índice PET indicou ambiente termicamente confortável em quase todos os horários para a estrutura florestal, ao passo que situa es favorecedoras de estresse por calor foram observadas na estrutura campo com estrato herbáceo contínuo, em todos os horários no ver o.Natural vegetation along river corridors plays an important role in the control and environmental quality of a region, since it establishes appropriate conditions for climate control. Undoubtedly, each structure of riparian vegetation should to a certain degree provide efficiency for such a role. However, what are the differences in responses between different types of structure?
