Desafios à pós-gradua o em forma o de professores na Universidade de Aveiro: das inten es às práticas
Maria Helena Sá Araújo e,Nilza Costa,Manuel Bernardo Canha,Isabel Alarc?o
Revista Portuguesa de Educa??o , 2002,
Abstract: This study analyses the impact of the recent masters courses at the Department of Didactics and Educational Technology of the University of Aveiro, Portugal, on the professional development of the basic and secondary school teachers that have attended those courses, as well as on their peers teaching practice. The outcomes, obtained from a questionnaire applied to the master teachers, indicate that, from their view point, the courses have produced effects on the professional development of the teachers that have attended them. However, they also reveal the need to plan strategies that lead to the production of such impact on other subjects.
Tres a?os estelares de política colonial borbónica (1701-1703)
De Bernardo Ares,José Manuel;
Cuadernos de historia de Espa?±a , 2006,
Abstract: the new colonial policies of the spanish monarchy are analyzed during a vital period of three years (1701-1703), which coincides with the political leadership of cardinal portocarrero and the enforcement of the alliance between portugal and the two bourbon crowns. the policies are characterized by french territorial expansion in the province of pensacola, the organization of the black slave trade and the attempts to create new trading companies, led by france and open to the legal trading of other countries. these processes, analyzed in the short span of three years, are included in the broader setting of the two consecutive wars of succession (english and spanish) to show the historical significance of the rise (france) and fall (spain) of empires. furthermore, they are influenced by, and, in turn, they themselves have an influence on, some reduced power elites, who make the decisions, redirecting those short, medium and long term processes towards new political horizons. in those three years, the sociological triangle responsible for these major decisions was constituted by the two secretaries of state of louis xiv (torcy and pontchartrain), the ambassadors of france in spain (harcourt, blécourt, marcin and d'estrées) and in portugal (rouillé) and the advisor on colonial affairs and president of the french guinea company (ducasse).

Modelo estocástico para estimación de valores económicos de rasgos productivos y funcionales en bovinos lecheros
Vargas-Leitón, Bernardo;Cuevas-Abrego, Manuel;
Agrociencia , 2009,
Abstract: in genetic improvement programs it is necessary to have estimators of the economic value of the traits that are to be selected. the objective of the present study was to construct a stochastic model to calculate the economic values of productive and functional traits in dairy cattle. the model uses distributions of probability and mathematical functions to simulate the productive-reproductive cycle of a dairy herd. the output parameters of the model are related to biological and economic efficiency, at the cow and herd level, per calender year. the economic values were estimated as partial regression coefficients in an analysis of multiple regression, with productive and functional traits as prediction variables and the gross margin as dependent variable. the significant (p<0.05) economic values (usd cow-1 year-1) of positive magnitude were: 39.3 (kg, peak milk production), 2.8 (days, length of lactation), 105.9 %, milk protein), 91.5 (%, milk fat), 33.4 (years, productive life), 0.07 (first day of mastitis), 0.28 (%, voluntary culling rate in heifers), 1.62 (%, dressing percentage). the significant economic values of negative magnitude were: -3.31 (days open), -8.21 %, involuntary culling rate in cows), -1.75 (%, involuntary culling rate in heifers), -6.69 (%, cow mortality) and -0.66 (%, clinical mastitis).
El índice de reemplazo etnolingüístico entre la población indígena de México
Ordorica, Manuel;Rodríguez, Constanza;Velázquez, Bernardo;Maldonado, Ismael;
Desacatos , 2009,
Abstract: this paper studies the transmission of indigenous languages through an analysis of the use of mother tongues across generations. it also shows the different conditions of the indigenous languages at the regional, state and municipal levels. it features a comparison of the indexed data for each of the 62 ethnolinguistic groups collected through two major demographic studies: the 2000 general census and the 2005 count of population and housing, which allow us measure the decline or recovery of indigenous languages in mexico.
Normas mínimas 2009 para el ejercicio de la anestesiología en Colombia: Comité de Seguridad Minimum standards 2009 for practising anaesthesiology in Colombia: Safety Committee
Pedro Ibarra,Bernardo Robledo,Manuel Galindo,Claudia Ni?o
Revista Colombiana de Anestesiología , 2009,
Abstract: Esta es una actualización de las Normas Mínimas del 2003. Sus cambios principales son la inclusión de la Lista de Chequeo, propuestas de formatos de evaluación preanestésica, registro intraoperatorio, registro de UCPA, y consentimiento informado. Además se agregan ítems que extienden el rol del anestesiólogo como participación en la tromboprofilaxis, profilaxis antibiótica, y definición explicita del manejo del dolor perioperatorio que son pilares de la medicina perioperatoria. Se incluye también la necesidad de generar bases de datos para registrar información perioperatoria y sugerencias para la disponibilidad y uso de medicamentos seguro. Por último se actualizan los laboratorios preanestésicos recomendados. This updates Minimum Standards 2003. The main changes concern including the Check List; proposals for preanaesthetic evaluation forms; intraoperative records; UCPA record; and informed consent. Items have also been added extending the anaesthesiologist′s role by participating in thromboprophylaxis, antibiotic prophylaxis and an explicit definition for managing perioperative pain as the main support for perioperative medicine. The need for generating databases for recording perioperative information and suggestions for the availability and use of safe medicaments are also included. The list of recommended preanaesthetic laboratories has also been updated.
Meromorphic continuation of functions and arbitrary distribution of interpolation points
Manuel Bello Hernández,Bernardo de la Calle Ysern
Mathematics , 2012,
Abstract: We characterize the region of meromorphic continuation of an analytic function $f$ in terms of the geometric rate of convergence on a compact set of sequences of multi-point rational interpolants of $f$. The rational approximants have a bounded number of poles and the distribution of interpolation points is arbitrary.
Multiple Criteria Analysis for Energy Storage Selection  [PDF]
Alexandre Barin, Luciane N. Canha, Alzenira R. Abaide, Karine F. Magnago, Breno Wottrich, Ricardo Q. Machado
Energy and Power Engineering (EPE) , 2011, DOI: 10.4236/epe.2011.34069
Abstract: In view of the current and predictable energy shortage and environmental concerns, the exploitation of renewable energy sources offers great potential to meet increasing energy demands and to decrease depend- ence on fossil fuels. However, introducing these sources will be more attractive provided they operate in conjunction with energy storage systems (ESS). Furthermore, effective energy storage management is essential to achieve a balance between power quality, efficiency, costs and environmental constraints. This paper presents a method based on the analytic hierarchy process and fuzzy multi-rules and multi-sets. By exploiting a multiple criteria analysis, the proposed methods evaluate the operation of storage energy systems such as: pumped hydro and compressed air energy storage, H2, flywheel, super-capacitors and lithium-ion storage as well as NaS advanced batteries and VRB flow battery. The main objective of the study is to find the most appropriate ESS consistent with a power quality priority. Several parameters are used for the investigation: efficiency, load management, technical maturity, costs, environmental impact and power quality.
Baterias de níquel-hidreto metálico, uma alternativa para as baterias de níquel-cádmio
Ambrosio, Renato Canha;Ticianelli, Edson Antonio;
Química Nova , 2001, DOI: 10.1590/S0100-40422001000200015
Abstract: nickel metal hydride (ni-mh) batteries have emerged as an alternative for replacement of nickel-cadmium batteries, because of their more environmental compatibility and high energy capacity. in this article, we described the properties and applications for ni-mh batteries, giving some emphasis on the metal-hydride electrode, including the description of composition, the charge storage capacity and the discharge profile. the key component of the nickel-metal hydride electrode is a hydrogen storage alloy whose composition is formulated to obtain a high stable material over a large number of charge-discharge cycles.
