A self-flotator vibrational prototype electromechanical drive for treatment of oil and water emulsion or like emulsion is presented and evaluated. Oil production and refining to obtain derivatives is carried out under arrangements technically referred to as on-shore and off-shore, ie, on the continent and in the sea. In Brazil 80 % of the petroleum production is taken at sea and area of deployment and it cost scale are worrisome. It is associated, oily water production on a large scale, carrier 95% of the potential pollutant of activity whose final destination is the environment medium, terrestrial or maritime. Although diversified set of techniques and water treatment systems are in use or research, we propose an innovative system that operates in a sustainable way without chemical additives, for the good of the ecosystem. Labyrinth adsor-bent is used in metal spirals, and laboratory scale flow. Equipment and process patents are claimed. Treatments were performed at different flow rates and bands often monitored with control systems, some built, other bought for this purpose. Measurements of the levels of oil and grease (OGC) of efluents treaty remained within the range of legal framework under test conditions. Adsorbents were weighed before and after treatment for obtaining oil impregna-tion, the performance goal of vibratory action and treatment as a whole. Treatment technolo-gies in course are referenced, to compare performance, qualitatively and quantitatively. The vibration energy consumption is faced with and without conventional flotation and self-flotation. There are good prospects for the proposed, especially in reducing the residence time, by capillary action system. The impregnation dimensionless parameter was created and confronted with consecrated dimensionless parameters, on the vibrational version, such as Weber number and Froude number in quadratic form, referred to as vibrational criticality. Re-sults suggest limits to the vibration intensity

From the context of the degree‘s creation of Spanish literature and language‘s course, at UFRN, came the motivation to make this research, that presents a literary study of a poet‘s group known as Generación del 27, that came in to light at Spain, on 1920. A lot of aspects of this study are themes of many others disciplines, of this degree (Spanish Literature II, IberianAmerican Literature, Spanish Culture, Translation in Spanish Language). This work will also serve as inspiration to new reflections and proposes of translations, as bridges between the language that goes and the other that comes. It is the Translation as comprehension‘s negotiation between languages, it is the decir casi lo mismo, here in poem‘s form (ECO, 2007), in the attempt to conclude new learning, that will be shared with undergraduate and graduate students, being at teaching area, extension or new researches. To contextualize this generation‘s studies, were elected the anthologies organized by Gerardo Diego, called Poesía Española (Antologías), published on 2007, by Ediciones Cátedras, and the Antología Comentada de La Generación del 27, wrote by Víctor García de La Concha, published on 2006, by Editorial Espasa Calpe. The research took Generacion Del 27 as their object of research and - from many others critical reading about the poetry made by those young poets, their creative vocation of aesthetics and vanguard – wanted to understand the context of literary‘s creation of those poets del 27. We form our foundation with contributions by Antonio Maravall (2009), Eugenio D‘ors (s.d) Severo Sarduy (1999), Lezama Lima (2011), Alfonso Reyes (1958) e Deleuze (2005) among others that brought the comprehension of the baroque‘s language, giving emphasis to pluridirectional movement, deconstructing it‘s linearity, creating others new forms, as returns, circles, spirals favoring encounters, detachment or equal points of departure and arrivals. In this way, the poets del 27 approached the baroque of six hundred on a re-reading, and made of the third centenary‘s celebration of the Góngora‘s a Mirada exuberante death, to the return of baroque‘s spirit. Alfonso Reyes e Rubén Darío said that real lights highlighted the paths of this poets generation: The light that desdobra scintillates on García Lorca, Jorge Gullén, Dámaso Alonso, Gerardo Diego and the bullfighter Ignacio Sánchez Mejías, poets that expressed tributes in big style to Soledades author, at Madrid‘s Caffe and all Spain.
