Vida y obra de Don Juan Suárez de Peralta : cronista y protoalbéytar de América : el hombre de las dos España (1541-1613)

Don Juan Suárez de Peralta nació en la ciudad de México-Tenochtitlán en 1541, habiendo sido sus padres Don Juan Suárez Marcayda y Doña Magdalena de Peralta; el padre también conocido como Juan Suárez de Ávila, o como Juan Suárez “El Viejo”, hizo la campaña militar de la conquista del Imperio Azteca como compañero de armas de Don Hernán Cortés. Suárez de Peralta escribió tres grandes obras: “Tractado de Alveiteria” hacia 1575, “Tractado de Cavallería de la Gineta y Brida” en 1580 y “Tractado del Descubrimiento de las Indias y su Conquista” en 1589. Estos tres tratados hacen de Suárez de Peralta, una inevitable y riquísima fuente de información para todo historiador investigando las vetas de la Historia Virreinal Novohispana y de la Historia de España del siglo XVI. Su obra sobre medicina equina y zootecnia de los caballos, es un magnífico y estupendo trabajo que se levanta como el primer libro de su tipo escrito en América. Suárez de Peralta asociado con su hermano mayor, Don Luis, establece un criadero de caballos de raza fina en Tacubaya, en el poniente de la antigua ciudad de México, y es ahí en donde aprende el arte científico de la médica equina, de la reproducción y de la zootecnia caballar y sus habilidades como jinete y gran caballista. En 1579, Don Juan debido a una serie de circunstancias decide exiliarse a España arribando al puerto de Sanlúcar de Barrameda, como huésped en el Palacio de su pariente el VII Conde-Duque de Medina Sidonia, para después habitar en Trujillo y en Sevilla en donde escribe y publica sus otras dos grandes obras. Se muda a Madrid en donde contrae nupcias con una aristócrata dama de la alta nobleza castellana, Doña Isabel Hurtado de Mendoza, perteneciente a la poderosa Casa del Infantado. Con ella procrea un hijo, llamado Don Lorenzo Suárez de Peralta, quien viaja a la Nueva España para tomar posesión de los bienes de su padre, su abuelo y de su tío Luís. Don Juan, nuestro albéitar, quien “alladese enfermo de calenturas”, fallece el 8 de enero de 1613 y es enterrado en la Iglesia del Spiritu Sanctus de los Clérigos Menores en el Madrid de los Austrias. Su manuscrito “Libro de Alveitería”, permaneció olvidado y sin publicar durante más de tres cientos años en la Biblioteca Nacional de Madrid, hasta que finalmente ve la luz en la ciudad de México, en ocasión del Centenario de la fundación de la Escuela Nacional de Medicina Veterinaria y Zootecnia y del IV Centenario de la Real y Pontificia Universidad de México, ahora, Universidad Nacional Autónoma de México (UNAM) en 195

Análise de volatilidade, integração de preços e previsibilidade para o mercado brasileiro de camarão

The present paper has the purpose of investigate the dynamics of the volatility structure in the shrimp prices in the Brazilian fish market. Therefore, a description of the initial aspects of the shrimp price series was made. From this information, statistics tests were made and selected univariate models to be price predictors. Then, it was verified the existence of relationship of long-term equilibrium between the Brazilian and American imported shrimp and if, confirmed the relationship, whether or not there is a causal link between these assets, considering that the two countries had presented trade relations over the years. It is presented as an exploratory research of applied nature with quantitative approach. The database was collected through direct contact with the Companhia de Entrepostos e Armazéns Gerais de São Paulo (CEAGESP) and on the official website of American import, National Marine Fisheries Service - National Oceanic and Atmospheric Administration (NMFS- NOAA). The results showed that the great variability in the active price is directly related with the gain and loss of the market agents. The price series presents a strong seasonal and biannual effect. The average structure of price of shrimp in the last 12 years was R$ 11.58 and external factors besides the production and marketing (U.S. antidumping, floods and pathologies) strongly affected the prices. Among the tested models for predicting prices of shrimp, four were selected, which through the prediction methodologies of one step forward of horizon 12, proved to be statistically more robust. It was found that there is weak evidence of long-term equilibrium between the Brazilian and American shrimp, where equivalently, was not found a causal link between them. We concluded that the dynamic pricing of commodity shrimp is strongly influenced by external productive factors and that these phenomena cause seasonal effects in the prices. There is no relationship of long-term stability between the Brazilian and American shrimp prices, but it is known that Brazil imports USA production inputs, which somehow shows some dependence productive. To the market agents, the risk of interferences of the external prices cointegrated to Brazilian is practically inexistent. Through statistical modeling is possible to minimize the risk and uncertainty embedded in the fish market, thus, the sales and marketing strategies for the Brazilian shrimp can be consolidated and widespread

Uso de resíduo e de minerais de pegmatito da região do seridó RN e de argilas portuguesas em formulações de grês porcelanato

In the State Rio Grande do Norte, Brazil, the most significant deposits of minerals in the production of granite and pegmatite are Seridó region. Municipalities of Parelhas and Equador are the main responsible for the production of feldspar, quartz, kaolin and granite. The ceramic industries are always in search of competitiveness by investing in new products or improving existing techniques. The stoneware is a type of pottery that stands in the market because it presents technical and aesthetic characteristics superior to other existing products. Characteristics of the raw materials initially obtained with chemical analysis and mineralogical analysis are crucial in getting a product that satisfies the conditions in a manufacturing process and is, in principle, directly related to the firing cycle. This research aimed at developing new formulations for the mass production of ceramic stoneware. The raw materials initially characterized were feldspar, quartz, kaolin and granite. As part of the research was developed at the University of Aveiro, in Portugal, we used two clays used in the production of Portuguese ceramics. The raw material Brazilian and Portuguese and the final product, both in Portugal and Brazil, were analyzed for X-ray fluorescence, X-ray diffraction, granulometric analysis, dilatometric analysis, thermal analysis and analysis of scanning electron microscopy (MEV). The specimens prepared at the University of Aveiro (DECV) were sintered at 10000C and 12000C and the specimens prepared in UFRN were sintered at 10000C, 10500C, 11000C, 11500C, 12000C, 12500C and 13000C, but the best results and demonstrating the presence of the mineral mullite were at temperatures of 12000C, 12500C and 13000C. The results showed that the granite waste used may be considered raw material of excellent quality for use in the ceramic industry and coating floors and more accurately by the industry of stoneware. Physical and mechanical tests conducted on samples of the formulations F01 and F02 developed in UFRN showed a water absorption and mechanical strength suitable for the stoneware

El discurso político en el contexto multicultural de las instituciones de la Unión Europea. El discurso político en español y en polaco

The comparative analysis of Polish and Spanish political discourse in the multilingual context of European institutions is challenging not only due to linguistic, cultural, geopolitical and social differences, but also because of a relatively short history of such contacts in the EU framework. Intercultural communication, as a dynamic social practice is a fascinating object of investigation. Bidirectional comparative analysis of Polish and Spanish oral texts allows define the barriers of such communication. It encompasses the discursive act together with its objectives, strategies and consequences, and also its raison d’être. It explains why different strategies reflected through discursive categories were used. Consequently it describes both, conditions and outcomes of identity negotiation. The latter is a political competence perceived and evaluated by the direct interlocutors, the participants of the political debate, and indirectly, by a public opinion of the European Union. That proves it is two-level communication. The negotiation of political identity through discourse, according to the Ting-Toomey theory, can lead to maintaining, loosing, recovering or reinforcing it282. The Identity Negotiation Theory includes the construction and development of personal, relational, role and desired identity and is one of the methodological axes of this investigation. Political identity consists of exhibiting necessary competences to efficiently participate in the legislation process, for example, in order to present amendments, promote a given ideology, participate in controversial discussions and manage conflicts, and, finally, gain the support of public opinion. The analysis of creation, negotiation, maintenance, recovery and promotion of the political identity is performed through the identification and description of discursive categories proposed by Van Dijk283 and adapted to the needs of this study. This is the second methodological axe of the investigation. The following questions arise: which discursive strategies, used by Polish and Spanish politicians, will be communication facilitators and which will be barriers hampering communication? Which strategies show political competencies of the speaker, his or her influence in the legal EU reality through discourse?...

Removal of paracetamol on biomass-derived activated carbon: Modeling the fixed bed breakthrough curves using batch adsorption experiments

The remediation of paracetamol (PA), an emerging contaminant frequently found in wastewater treatment plants, has been studied in the low concentration range (0.3–10 mg L−1) using as adsorbent a biomass-derived activated carbon. PA uptake of up to 100 mg g−1 over the activated carbon has been obtained, with the adsorption isotherms being fairly explained by the Langmuir model. The application of Reichemberg and the Vermeulen equations to the batch kinetics experiments allowed estimating homogeneous and heterogeneous diffusion coefficients, reflecting the dependence of diffusion with the surface coverage of PA. A series of rapid small-scale column tests were carried out to determine the breakthrough curves under different operational conditions (temperature, PA concentration, flow rate, bed length). The suitability of the proposed adsorbent for the remediation of PA in fixed-bed adsorption was proven by the high PA adsorption capacity along with the fast adsorption and the reduced height of the mass transfer zone of the columns. We have demonstrated that, thanks to the use of the heterogeneous diffusion coefficient, the proposed mathematical approach for the numerical solution to the mass balance of the column provides a reliable description of the breakthrough profiles and the design parameters, being much more accurate than models based in the classical linear driving force.

Effects of infiltration pressure on mechanical properties of Al–12Si/graphite composites for piston engines

In this work results for the flexural strength and the thermal properties of interpenetrated graphite preforms infiltrated with Al-12wt%Si are discussed and compared to those for packed graphite particles. To make this comparison relevant, graphite particles of four sizes in the range 15–124 μm, were obtained by grinding the graphite preform. Effects of the pressure applied to infiltrate the liquid alloy on composite properties were investigated. In spite of the largely different reinforcement volume fractions (90% in volume in the preform and around 50% in particle compacts) most properties are similar. Only the Coefficient of Thermal Expansion is 50% smaller in the preform composites. Thermal conductivity of the preform composites (slightly below 100 W/m K), may be increased by reducing the graphite content, alloying, or increasing the infiltration pressure. The strength of particle composites follows Griffith criterion if the defect size is identified with the particle diameter. On the other hand, the composites strength remains increasing up to unusually high values of the infiltration pressure. This is consistent with the drainage curves measured in this work. Mg and Ti additions are those that produce the most significant improvements in performance. Although extensive development work remains to be done, it may be concluded that both mechanical and thermal properties make these materials suitable for the fabrication of piston engines.
