Victoria. The crop was planted on June 1 at a density of 7.5 pl m-2 in both climates. In Cocula, maximum and minimum temperatures were more extreme and rainfall was more intense, while soil was poor in total nitrogen, compared with Montecillo. Crop growth, yield and its components, and water use efficiency were affected significantly by the environment, nitrogen and the interaction environment * nitrogen. The crop cycle in the hot environment was 36 days shorter, with a greater accumulation of HU and ETc. Yield and its components and water use eff...

We report a detailed analysis where the complete set of Hamilton-Jacobi constraints, the characteristic equations and the gauge transformations of the theory are found. We find from integrability conditions on the Hamilton-Jacobi Hamiltonians that the theory is reduced to a BF field theory defined only in terms of self-dual (or anti-self-dual) variables; we identify the dynamical variables and the counting of physical degrees of freedom is performed. In addition, we compare our results with those reported by using the canonical formalism.

En primer lugar, revisaremos el papel que cada dramaturgo tuvo en la traducción de obras italianas al español, y viceversa. A continuación, recopilaremos las fichas bibliográficas y los datos de representación y composición de ambos textos. Después, contrastaremos los personajes, acotaciones y episodios argumentales de la comedia de Laviano y el drama de Gozzi. Sobre esta comparación, propondremos que El cadalso para su dueño pudo constituir la verdadera fuente no reconocida de Gozzi para la escritura de Cimene Pardo. Palabras claVE: drammi spagnoleschi, comedia heroica española, El cadalso para su dueño y los Pardos de Aragón, traducción, Carlo Gozzi, Manuel Fermín de Laviano.

Marcial a Don Manuel Fermín de Laviano, sátira escrita por Juan Pablo Forner. En primer lugar, se sitúa el texto en el desarrollo de la carrera dramática de Manuel Fermín de Laviano en el periodo 1779-1783 y las celebraciones regias celebradas en agosto y septiembre de 1783. Después, se edita la Carta tras el cotejo de los dos manuscritos en que se ha conservado. A continuación, se comenta su contenido como fruto de la respuesta erudita de rechazo a las estrategias autoriales adoptadas por Laviano para construir una imagen pública como escritor culto. Por último, se destaca el lugar de esta Carta en la historia de las polémicas literarias españolas del siglo XVIII, en las que la poética neoclásica establece un paradigma reglado y autorizado que condiciona la escritura como acceso a los círculos literarios cultos.

Para ello, cotejaremos los testimonios del Cantar datados en este siglo (entre ellos, las copias de fray Sarmiento y Cándido María Trigueros) con una copia de comienzos del siglo xvi y el codex unicus medieval. Siguiendo el método crítico del error significativo, filiaremos los testimonios para detectar posibles nuevos subarquetipos en la transmisión manuscrita del Cantar desde la Edad Media hasta el siglo xviii, y que pudieron ser determinantes para el conocimiento del texto en el Siglo de las Luces. Palabras clave: crítica textual; estema; Disertación sobre el verso suelto y la rima; destierro del Cid; épica.

We report the complete set of HJ Hamiltonians and a generalized HJ differential from which all symmetries of the theory are identified. Moreover, we show that in spite of PCS Lagrangian produces Einstein's equations, the generalized HJ brackets depend on a Barbero-Immirzi like parameter. In addition we complete our study by performing a canonical covariant analysis, and we construct a closed and gauge invariant two form that encodes the symplectic geometry of the covariant phase space.

We report the complete set of Faddeev-Jackiw constraints and we identify the corresponding generalized Faddeev-Jackiw brackets. With these results, we show that although P-CS produces Einstein’s equations, the generalized brackets depend on a Barbero-Immirzi-like parameter. In addition, we compare our results with those found in the canonical analysis showing that both formalisms lead to the same results.

Thereafter, via a suitable partial gauge-fixing procedure, the time gauge, we calculate the quantization bracket structure (generalized Faddeev-Jackiw brackets) for the dynamic variables and confirm that the number of physical degrees of freedom is one. This approach provides an alternative to explore the dynamical content of massive gravity models. CyT under grand number CB-2014-01/240781. We would like to thank G. Tavares-Velasco for reading a draft version of this paper and alerting us to various typos.

The Faddeev-Jackiw constraints and the generalized Faddeev-Jackiw brackets are reported; we show that in spite of the Pontryagin and Euler classes give rise the same equations of motion, its respective symplectic structures are different to each other. In addition, a quantum state that solves the Faddeev-Jackiw constraints is found, and we show that the quantum states for these invariants are different to each other. Finally, we present some remarks and conclusions.
