El Palacio de los Leones de la Alhambra: Madrasa, zāwiya y tumba de Mu ammad V? Estudio para un debate
Ruiz Souza, Juan Carlos
Al-Qantara : Revista de Estudios Arabes , 2001,
Abstract: This article shows a new interpretation of the function of the famous Court of Lions in the Alhambra of Granada, built in the 1360's by Mu ammad V. The study of the contemporary architecture in the Maghreb (Fez, Sale, Tlemcen, etc.), the close relations between Mu ammad V of Granada and the neighbouring Islamic countries, his own knowledge of the architecture produced under the Marinid dynasty during his Moroccan exile in Fez from 1359 to 1362, etc., makes us reconsider the Palace of the Lions as a royal madrasa-zāwiya, where its founder could even have been buried in 1391. Moreover, this hypothesis would clearly explain the numerous anomalies the Palace of Lions presents. Este trabajo presenta una lectura novedosa sobre la funcionalidad del celebérrimo Patio de los Leones de la Alhambra de Granada, construido en la década de los sesenta del siglo XIV por Mu ammad V. El estudio de la arquitectura coetánea del Magreb (Fez, Salé, Tremecén, etc.), las intensas relaciones existentes entre Mu ammad V y los países islámicos vecinos, el propio conocimiento de Mu ammad V de la arquitectura meriní durante su exilio marroquí en Fez entre 1359 y 1362, etc., nos han hecho interpretar el Palacio de los Leones como una madrasa-zāwiya real, donde su fundador incluso pudo ser enterrado en 1391. Esta hipótesis, además, explicaría las numerosas anomalías que presenta el Palacio de los Leones.

Abstract: Foram apresentadas as altera es hematológicas do sangue periférico e da medula óssea em pacientes expostos cronicamente ao benzeno. Foram descritos a biotransforma o metabólica e os possíveis mecanismos envolvidos neste tipo de toxicidade. Os dados hematológicos do sangue periférico s o mostrados e avaliados em sua importancia, sendo a macrocitose e a linfocitopenia sinais precoces de toxicidade ao benzeno. As altera es da medula óssea observadas s o demonstradas pelos métodos complementares citológico e histológico. A anormalidade histológica de maior importancia foi a hipocelularidade global devida principalmente ao setor granulocítico. Foi observado também aumento do percentual de eosinófilos, de mastócitos e de atipias no setor megacariocítico. Foram observadas altera es de caráter inflamatório e ressaltada a presen a de sinais de dismielopoiese. Foram enfatizadas a necessidade da valoriza o das altera es hematológicas do sangue periférico e a vis o critica e global desse importante problema de saúde pública.
ANALISIS POR ELEMENTOS FINITOS DE LA PROPAGACIóN DE GRIETAS CIRCULARES DURANTE LA INDENTACIóN DE SISTEMAS RECUBIERTOS
EDUARDO A. PéREZ RUIZ,ROBERTO MARTINS DE SOUZA
Scientia Et Technica , 2004,
Abstract: Al someter un sistema recubierto al ensayo de indentación, frecuentemente se desarrollan esfuerzos y campos de deformación en las películas finas depositadas. Este trabajo tiene como objetivo estudiar los campos de esfuerzos que se desarrollan durante la indentación de los sistemas metálicos recubiertos con películas finas. Durante el proceso de indentación se consideró un indentador esférico, el cual aplica una carga de 50N sobre el sistema recubierto. Los resultados fueron obtenidos utilizando el método de los elementos finitos (MEF) a través del software ABAQUSa, con una malla bidimensional axisimétrica. Los resultados permitieron analizar la propagación de las grietas circulares en función de los esfuerzos desarrollados en la superficie de la película.

Abstract: purpose: to evaluate the performance of support vector machine, multi-layer perceptron and radial basis function neural network as auxiliary tools to identify keratoconus from orbscan ii maps. methods: a total of 318 maps were selected and classified into four categories: normal (n = 172), astigmatism (n = 89), keratoconus (n = 46) and photorefractive keratectomy (n = 11). for each map, 11 attributes were obtained or calculated from data provided by the orbscan ii. ten-fold cross-validation was used to train and test the classifiers. besides accuracy, sensitivity and specificity, receiver operating characteristic (roc) curves for each classifier were generated, and the areas under the curves were calculated. results: the three selected classifiers provided a good performance, and there were no differences between their performances. the area under the roc curve of the support vector machine, multi-layer perceptron and radial basis function neural network were significantly larger than those for all individual orbscan ii attributes evaluated (p<0.05). conclusion: overall, the results suggest that using a support vector machine, multi-layer perceptron classifiers and radial basis function neural network, these classifiers, trained on orbscan ii data, could represent useful techniques for keratoconus detection.

Journal of Building Construction and Planning Research (JBCPR) , 2016, DOI: 10.4236/jbcpr.2016.41005
Abstract: The aim of this study is to apply the methodology for assessment of environmental impact whether of a physicochemical nature and on the biodiversity and ecosystems, or whether sociocultural and economic aspects of the historic towns with tourism interest that are assessed. The automated method of the RIAM software is used which requires a baseline study of the environment of different towns to be prepared. In addition, the analysis of the social perception on tourism of the local people from the course work of students at the UIDE shall be applied. The conclusions of the case studies undertaken allow for strategic proposals and recommendations to be prepared so that they can be incorporated into the management plans for tourism in the historic towns with heritage value.
Incorporation of Environmental and Sustainable Indicators in Universities  [PDF]
Lourdes Ruiz
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.76075
Abstract:

The use of environmental and sustainable indicators of global organizations has greater advantages than those of national initiatives or those developed by researchers in said subject, due to the fact that they have a much broader scope for sustainability, have been applied in a systematic manner and therefore have greater comparability and reliability. The environmental indicators are constructed from the approaches to sustainable development in universities with regards to the social, economic, institutional and environmental dimensions in the organizations. This work involves the application of environmental and sustainable indicators for internationally recognized efficiency in university activities, which contribute towards organizing, summarizing and developing the processes for development planning and environmental management.
