Humor and National Catharsis in Roberto Cossa's El saludador

This article examines humor in Roberto Cossa’s El saludador and proposes that, through his unique blend of comic forms, the playwright manipulates audience reaction and provokes catharsis in his spectators. Cossa creates a comic protagonist who is a surrogate for the Argentine nation. Through their identification with the humorous protagonist/nation, spectators can consider their own reaction to the abuses the nation has suffered or self-imposed. Unlike earlier Cossa plays, which may have impeded audience catharsis, the spectator/protagonist/nation identification in El saludador promotes catharsis through audience laughter and allows spectators to purge themselves of economic and political fears in the aftermath of recent events in Argentina’s history.

Martí, Monologue, and the Metaphorical Dawn in Raúl de Cárdenas's Un hombre al amanecer

Un hombre al amanecer by Cuban playwright Raúl de Cárdenas traces and reflects upon the life of nineteenth-century Cuban patriot and writer José Martí, the play’s only character. However, three dramatic techniques – the interweaving of four types of monologue, the juxtaposition of past and present, and the incorporation of Martí’s own writings into the play – move the play’s focus away from Martí and toward a more contemporary view of a Cuban writer’s relationship to his nation. This article examines the play’s complicated structure and shows how Cárdenas fuses multiple perspectives on Martí’s life and writings to expose his own ambivalent relationship with Cuba, a relationship that is as poignant to the present-day writer as it was for his nineteenth-century predecessor/protagonist (GAB)

Aspects of the chemistry of differentiation in some protista

Several species of Actinomyces viscosus were examined using the scanning electron microscope and considerable morphological heterogeneity was seen and one species, Actinomyces viscosus WVU 398B, was observed to undergo a form of differentiation, for which the term 'vacuolation' has been introduced. This form of differentiation can be regulated by inhibitors of peptidyl transferase or translocase. Further examples of the regulation of differentiation were provided by an examination of the interaction of antibiotics and antimetabolites with a species of Bacillus cereus isolated from laboratory dust. 3-chloropropane-1-2-diol exhibited an ability to impair cell division in Staphylococcus aureus and Escherichia coli and this action may be due to the glycerol antagonism of 3-chloropropane-1,2-diol.

Chelating Agents and the Regulation of Metal Ions

Up to about the early 1980s it was perhaps still possible to summarize in a review of a moderate length the development of the medicinal applications of chelation chemistry and the exploitation of such chemistry in regulating the metal ion concentrations in the body. However, in the last few years there has a great surge in the development of chelation chemistry and its usage in medicine and related areas of life sciences research. It is no longer the case that such a review primarily concentrates upon the use of chelating agents in removing toxic metals from the body but it must now cover the use of chelating agents in the imaging procedures nuclear medicine and magnetic resonance imaging (MRI), the use of chelating agents in unravelling the biochemistry of reactive oxidative species (ROS) and the control and measurement of intracellular calcium ions. It is in the recent applications that there have been the greatest developments over the last ten years

Strutjet Matures to Support Propulsion Needs in the 2000+ World

The Strutjet, Aerojet's Rocket Based Combined Cycle (RBCC) concept, was discussed in a previous ISABE paper as an enabling propulsion concept for single stage to orbit applications. This paper describes the technical progress of the Strutjet since 1996 together with a rationale why RBCC engines in general and the Strutjet in particular, lend themselves uniquely to systems having the ability to expand current space and also open new global "rapid delivery" markets. In particular, the paper substantiates the claims why for certain missions RBCC powered vehicles can be operated at higher margins than all rocket systems, and why within the family of conceivable RBCC systems the Strutjet excels due to its unique architecture and design features. A special emphasis is given to the selection of the engine's ram/scram mode design point because only that mode can add significantly to the mission effective Isp. The thrust produced by an airbreathing engine is directly related to the mass of air processed. This air is captured by the inlet and compressed to raise the pressure for combustion and subsequent expansion. The net accelerating force is the difference between the gross thrust and total vehicle drag (including the spill drag). This total drag is highest at low speeds when the gross thrust is lowest. When the net accelerating force is low, most of the fuel burned is wasted overcoming the vehicle drag. Higher thrust is necessary to perform the mission. One method is to leave the rockets on longer but this results in much higher propellant consumption

Strutjet-powered reusable launch vehicles

Martin Marietta and Aerojet are co-investigating the feasibility and viability of reusable launch vehicle designs. We are assessing two vehicle concepts, each delivering 8000 lb to a geosynchronous transfer orbit (GTO). Both accomplish this task as a two-state system. The major difference between the two concepts is staging. The first concept, the two-stage-to-orbit (TSTO) system, stages at about 16 kft/sec, allowing immediate return of the first stage to the launch site using its airbreathing propulsion system for a powered cruise flight. The second concept, the single-stage-to-orit (SSTO) system, accomplishes stage separation in a stable low earth orbit (LEO)

Desviaciones disfrutadas y pasiones visualizadas: Demonios en la piel: La pasión según Pasolini

Al escenificar un laberinto visual e intertextual muy intricado, arraigado en la historia y el arte culto, Demonios en la piel provoca un cuestionamiento de los comportamientos y normas sociales aceptados y de las diversas maneras de las sociedades para enfrentarlas, marginarlas o condenarlas. Este ensayo examina la repetición de tres imágenes específicas en la obra para mostrar como éstas manipulan la focalización de los espectadores para animarlos a ver las hipocresías que ellos mismos fomentan. Al centrarse de manera humorística y sofisticada en las pasiones del cineasta pintoresco pero controversial, Pier Paolo Pasolini, Eduardo Adrianzén y Diego La Hoz construyen una experiencia teatral entretenida e intelectual que tiene resonancias locales y globales. Through the staging of a complex visual and intertextual labyrinth rooted in history and highbrow art forms, Peruvian playwright Eduardo Adrianzén’s Demonios en la piel provokes the questioning of socially accepted norms and behaviors and the diverse ways that societies confront, marginalize, or condemn them. This essay examines the repetition of three specific images in the play to show how these maneuver spectators’ focus, encouraging them to open their eyes to the hypocrisies that they themselves foment. By humorously and intelligently highlighting the passions of the colorful but controversial Italian filmmaker, Pier Paolo Pasolini, the play creates a sophisticated theatrical experience that resonates in contemporary Peru and throughout the world

La vida no es una telenovela: técnica y estética en el teatro de Eduardo Adrianzén

Lo que sorprende en las obras teatrales de Eduardo Adrianzén no es siempre la temática, aunque, sin duda, los temas que este dramaturgo peruano selecciona nunca se alejan de las controversias religiosas, políticas y personales. No obstante, la manera original en que Adrianzén entreteje sus historias es lo que le permite indagar en los traumas más profundos de su nación y de la humanidad. En este trabajo se descifran algunas de las técnicas teatrales que Adrianzén emplea en una de sus obras más recientes, Respira, para revelar por qué esta y otras obras suyas logran agradar tanto a su público y siguen ganando premios, aun cuando presentan fuertes condenas de las instituciones religiosas, políticas y sociales e incluso cuandocritican a los mismos receptores que forman el público que las aprecia
