Se estudió el comportamiento agroindustrial de seis variedades de caña de azúcar en caña planta (CP.73-1547; Cp. 74-2005 Cp. 63-588; CP.72-1210) en comparación con la variedad L 72-3 utilizada como testigo: La plantación se realizó el 10 de diciembre de 1986, en terrenos de la Estación Experimental de caña de Azúcar. Sobre un suelo rojo (serie Chila matillo), bajo condiciones de riego; realizándose la cosecha a los 12 meses de edad , el 10 de diciembre de 1987: como criterios de evaluación se determinaron; brotacion; altura, población, floración, rendimiento agrícola, industrial y agro-industrial, utilizándose un diseño de bloques completos al azar y sometiendo los resultados análisis de varianza y prueba de Duncan al 5%: las variedades que obtuvieron el mejor comportamiento en el rendimiento agrícola fueron: CP. 63-538; Cp. 72-2036 y Cp. 74-303; Cp.72-2086; CP 73-1547 y Cp.63-583.

Gvzman de Alfarache é um dos mais extensos e Importantes romances picarescos de que se tem noticia. Foi publicado, inicialmente, em duas partes: a primeira, em Madri, em 1599, intitulada ‘Primera parte de la vida dei P. Ícaro Gvzman de Alfarache’, a segunda, em Barcelona, em 1605, com o titulo ‘Segvnda parte de la vida de Gvzman de Alfarache, atalaya de la vida humana, por Mateo Aleman, su verdadero autor’. Consta que, em 1602, por ter sido publicada uma segunda parte apócrifa escrita pelo advogado valenciano Juan José Marti, Alemán acrescentou ao título a informação ‘su verdadeiro autor’. O romance é a autobiografia de um velhaco que depois de aventuras de todo gênero, conta com detalhes, a sua vida em tom cético e pessimista, com o estoicismo espanhol e características típicas do Barroco. Em seis anos o romance teve vinte e três edições e foi traduzido para o francês, o inglês e o italiano. Alemán utilizou pela primeira vez o termo pícaro para simbolizar a humanidade propensão crime

El trabajo analiza los precios de la electricidad del mercado diario español. En el mismo se realiza un estudio del mercado eléctrico español y sus componentes junto con un análisis de los cambios regulatorios más significativos durante el periodo muestral. A partir de allí, se analiza la muestra a través de los estadísticos descriptivos principales. Luego se presenta un modelo general que es analizado a partir de los resultados empíricos principales obtenidos con su estimación. Finalmente, se realizan ajustes al mismo para obtener un modelo simplificado que se ajuste mejor a lo que se quiere conseguir, que es analizar la evolución de los precios de la electricidad. Los resultados del ajuste arrojan que los precios horarios dependen en su mayor parte de los precios de las horas anteriores. También que el modelo recoge muy bien la estacionalidad mensual y horaria que presenta la muestra. Por otro lado, características de la serie de precios como son la volatilidad y los saltos no quedan bien recogidos por el modelo, lo que lleva a plantearse la búsqueda de modelos alternativos.

The routing scheme and some permutation properties of a four-shuffle-exchange-based Omega network are discussed. The corresponding optical setup, which is composed of 2-D phase spatial light modulators and calcite plates, is proposed and demonstrated through mapping the inputs to a 2-D array. Instead of one shuffle-exchange followed by one switching operation as in ordinary Omega networks, in our presented system, the shuffle interconnection embraced in the switches is accomplished simply by varying the switching structure of each stage. For the proposed polarization-optical modules, the system is compact in structure, efficient in performance, and insensitive to the environment.

提出一种光瞳滤波器来同时实现横向超分辨和轴向焦移效应的电控制.该光瞳滤波器由两偏光镜及包含有径向双折射元件的任意偏振态的电控旋光器组成。利用径向双折射元件对光偏振态的空间调制作用,结合旋光器对任意偏振态光的旋光作用,与两个偏光镜结合,实现了空间偏振态的重新分布.利用庞加莱球及琼斯理论进行了分析,结果表明,借助这种电致位相延迟来实现的偏振态调制效应,可同时实现横向超分辨与轴向焦移效应。对能够同时获得横向超分辨与轴向焦移的情况进行了分析,得到了系统各组成参量及电光调制范围。

Background: There has been a significant growth in the prevalence of allergy, mainly associated to IgE-mediated disorders such as asthma and rhinitis. The identification of atopy in asthmatic patients through the measurement of specific IgE can help to identify risk factors that cause asthmatic symptoms in patients. The development and use of individualized allergen-based tests by the Component Resolved Diagnosis has been a crucial advance in the accurate diagnosis and control of allergic patients. The objective of this work was to assess the usefulness of molecular diagnosis to identify environmental allergens as possible factors influencing the development and manifestation of asthma in a group of asthmatic patients from Iran. Methods: Studied population: 202 adult asthmatic patients treated at the Loghman Hakim Hospital and Pasteur Institute of Teheran (Iran) from 2011 to 2012. Specific IgE determined by the ImmunoCAP system were used to both evaluate the patients' atopic condition and the molecules involved in the allergic sensitization. SDS-PAGE IgE-immunoblotting associated with mass spectrometry was carried out to study the cockroach IgE-binding sensitizing proteins. Results: Forty-five percent of all patients could be considered atopic individuals. Eighty-two percent of atopic patients were sensitized to pollen allergens. The Salsola kali (Sal k 1) and the Phleum pratense (rPhl p 1 and/or rPhl p 5) major allergens were the most common sensitizers among pollens (71% and 18%, respectively). Thirty-five percent of the atopic population was sensitized to cockroach. Four different allergens, including a previously unknown alpha-amylase, were identified in the cockroach extract. No significant associations could be demonstrated between the severity of asthma and the specific IgE levels in the atopic population. Statistical analysis identified the Sal k 1 as the main protein allergen influencing the development and expression of asthma in the studied population. Conclusions: Pollen and cockroach were the most relevant allergen sources in the asthmatic population. The Salsola kali major allergen was the main cause for sensitization in the atopic patients suffering asthma. Using the Component Resolved Diagnosis, it was possible to identify a new Blattella germanica cockroach allergen (Blattella alpha amylase 53 kDa) that could sensitize a relevant percentage of this population.
