Orbit design for future SpaceChip swarm missions in a planetary atmosphere
No full textThe effect of solar radiation pressure and atmospheric drag on the orbital dynamics of satellites-on-a-chip (SpaceChips) is exploited to design equatorial long-lived orbits about the oblate Earth. The orbit energy gain due to asymmetric solar radiation pressure, considering the Earth's shadow, is used to balance the energy loss due to atmospheric drag. Future missions for a swarm of SpaceChips are proposed, where a number of small devices are released from a conventional spacecraft to perform spatially distributed measurements of the conditions in the ionosphere and exosphere. It is shown that the orbit lifetime can be extended and indeed selected through solar radiation pressure and the end-of-life re-entry of the swarm can be ensured, by exploiting atmospheric drag
"Ponernos el espejo por delante": Staging Race in Alejandro Tapia y Rivera's La cuarterona
No full textÚnico por ser texto abolicionista escrito para estrenarse en la esfera pública del teatro, La cuarterona (1867), del puertorriqueño Alejandro Tapia y Rivera, ofrece un estudio nítido de las operaciones de la raza en el Caribe hispánico colonial. Este artículo considera el contexto de la creación y la performance del drama, las conexiones entre la obra y otros textos abolicionistas narrativos, y la cuestión de cómo y por qué Tapia se vale del teatro para tratar el tema de la raza y el colonialismo. Semejante a otros textos decimonónicos, La cuarterona proyecta la imagen de una identidad colectiva emergente que refleja el reformismo liberal de la época. Como pieza de teatro, sin embargo, se distingue por su presentación de la dinámica del poder ver y ser visto en una sociedad en la cual las identidades raciales híbridas hacían que la diferencia racial se hiciera cada vez más difícil de percibir.

Hispanic Caribbean Theatre on the Move: Crossing Borders, Redefining Boundaries
No full textThis essay reflects on the disciplinary trajectory of a course that I have taught both in foreign languages and literatures and in ethnic studies on the theme of migration in Hispanic Caribbean theatre. Crossing disciplinary borders sharpens our understanding of how theatrical performance has registered the complex social, economic, and political networks that connect the Hispanic Caribbean to the United States. Moreover, I argue that the viewing of Cuban, Dominican, and Puerto Rican theatre through a diasporic and transnational lens helps explain in part its marginalization in Latin American theatre studies, a field still dominated by national frames of reference. Exploring interdisciplinary approaches to teaching Latin American theatre not only resists the “border control” exerted by institutional units and academic disciplines but also helps redefine the field and spotlight its unique contributions to social scientific and humanistic inquiry.Peer reviewed
The Haunted Puerto Rican Stage: Lucy Boscana in La Carreta and Vejigantes
No full textThis article examines the figure of Lucy Boscana who was cast as counterpoint archetypal mothers of the national family in René Marqués’s La carreta (1952) and Francisco Arriví’s Vejigantes (1958). I contend that Lucy Boscana’s repeat performances – over 800 of them – of the jíbara mother Doña Gabriela haunts the Puerto Rican stage to the extent that it eclipses the Afro-Puerto Rican mother Mamá Toña in the Puerto Rican cultural memory. My argument considers the use of blackface and the construction of the female body as object of the male gaze as central factors in the erasure of black subjectivity from the Puerto Rican stage.Peer reviewed
"Home is Where Theatre is": Performing Dominican Transnationalism
No full textThis essay argues that a transnational approach to Dominican performance reveals a wealth of theatrical activity that addresses Dominican-U.S. migration. Like the characters in their plays who perform the social scenarios of migration, the creative endeavors of playwrights and performers such as Elizabeth Ovalle, Zaida Corniel, Chiqui Vicioso, and Josefina Báez are psychically and materially invested in more than one geopolitical space. Framed by critical approaches from Latino theater studies and migration studies, the analysis of the theme of return migration in four pieces by these authors shows that for transnational migrants, “home” can be conceived of as pluri-local and mobile. Their plays thus help to re-conceptualize dominicanidad from a diasporic perspective and to counter stereotyped portrayals of Dominican migration.Peer reviewed
The Aesthetics of Minor Transnationalism in the Theater of Frank Disla
No full textThis essay argues that the search for a new audience, for new stories, and for a new aesthetics in the theater of Frank Disla is emblematic of the dialogue transnational Dominican theater practitioners have begun with the national “script” for Dominican culture and identity. I suggest that the insistent formal experimentation in plays about migration by Disla is suggestive of the transnational artist’s pursuit of new forms of political and artistic belonging. Not only do Disla’s characters explore the ontological condition of belonging to more than one society (or perhaps none), his own dramatic oeuvre occupies an unsure space in literary history as well.Peer reviewed
Kademuren: Haalbaarheidsonderzoek naar een Camilla caisson voor grote kerende hoogtes
No full textHet afstudeerwerk betreft het uitwerken van een patent van de Ballast Nedam Groep. Het patent heeft betrekking op een caisson gebruikt als kademuur. Het afstudeerwerk is geheel volbracht binnen de Ballast Nedam Groep, in een tijdsbestek van 9 maanden, 1 september 1985 tot 30 mei 1986. Het patent omvat een caisson als kadeconstructie. De Caisson is genaamd Camilla caisson. Kenmerkend hieraan, is de naar achteren hellende achterwand en bijbehorende uitsparing in de bodemplaat. In het eerste deel van het afstudeerwerk is de veronderstelde optredende reductie van de horizontale grondkracht op de schuine achterwand van de caisson in gebruiksfase onderzocht. Dit is gebeurt met en semi-plastisch, interactief, eindige elementen methode programma. Deze studie is uitgevoerd bij de sectie Geotechniek. In het tweede deel van het afstuderen is een ontwerpproces doorlopen. Er is een inventarisatie gemaakt van mogelijke soorten kadeconstructies. Van deze kadeconstructies is een eerste selectie gemaakt. In een volgende fase is van de overgebleven kadeconstructies een ontwerpberekening gemaakt. Aan de hand van de hieruit voortkomende afmetingen voor de constructie is een prijscalculatie opgesteld. Hierna zijn de uitwendige afmetingen van de Camilla caisson voor een kerende hoogte van 30 meter, geoptimaliseerd. Met de hieruit voort gekomen resultaten, zijn de mogelijke uitvoeringswijze van de caisson bekeken. De studie eindigt met een vergelijking tussen een traditioneel caisson en het Camilla caisson.Hydraulic EngineeringCivil Engineering and Geoscience
Laparoscopic versus open repair of perforated peptic ulcers: analysis of outcomes and identification of predictive factors of conversion
No full textBackground The surgical treatment for perforated peptic ulcers (PPUs) can be safely performed laparoscopically. This study aimed to compare the outcomes of patients who received different surgical approaches for PPU and to identify the predictive factors for conversion to open surgery. Methods This retrospective study analyzed patients treated for PPUs from 2002 to 2020. Three groups were identified: a complete laparoscopic surgery group (LG), a conversion to open group (CG), and a primary open group (OG). After univariate comparisons, a multivariate analysis was conducted to identify the predictive factors for conversion. Results Of the 175 patients that underwent surgery for PPU, 104 (59.4%) received a laparoscopic-first approach, and 27 (25.9%) required a conversion to open surgery. Patients treated directly with an open approach were older (p < 0.0001), had more comorbidities (p < 0.0001), and more frequently had a previous laparotomy (p = 0.0001). In the OG group, in-hospital mortality and ICU need were significantly higher, while the postoperative stay was longer. Previous abdominal surgery (OR 0.086, 95% CI 0.012-0.626; p = 0.015), ulcer size (OR 0.045, 95% CI 0.010-0.210; p < 0.0001), and a posterior ulcer location (OR 0.015, 95% CI 0.001-0.400; p = 0.012) were predictive factors for conversion to an open approach. Conclusion This study confirms the benefits of the laparoscopic approach for the treatment of PPUs. Previous laparotomies, a greater ulcer size, and a posterior location of the ulcer are risk factors for conversion to open surgery during laparoscopic repair
