El compromiso social y el futuro de Aztlán: El mestizaje en La raza Cósmica (1925) de José Vasconcelos y la novela Crisol (1984) de Justo S. Alarcón
No full textabstract: Addressing the pending problem of understanding and interpreting the baroque discourse and multiple symbols in the third part, Realización, of the trilogy Crisol (1984) by Justo S. Alarcón, this study compares the vision of mestizaje, or miscegenation, in the said trilogy part and La Raza Cósmica (1925) by José Vasconcelos. To do this, we examine existing research on the two authors and we particularized the conception of mestizo, taking into account its expression in Mexico and the United States (U.S.). To analyze the text by Alarcón, our critical framework is based on fables and their didactic function as represented by the parables in the Bible and their moral functions as personified in the fables by Aesop and other writers. Although both authors predict the birth of a new race, we found that Vasconcelos, in a Utopian way, claims it would rise in Mexico. This new race, according to Vasconcelos, will be the product of hybridization between four races: white, yellow, red or Native American, and black. Justo S. Alarcón, on the other hand, suggests in Realización that such hybridization will take place in the United States, specifically the Southwest. Using analogies, allegories, and parables, the narrator presents several Aesopian characters that engage in massive and repeated migrations that ultimately produce a new crisol or melting pot. Such new hybridization takes place in the U.S. This study draws attention to the origin of the Chicano and the issue of identity. Future work could focus on both issuesDissertation/ThesisM.A. Spanish 201

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
The astrochemical observatory: Computational and theoretical focus on molecular chirality changing torsions around O – O and S – S bonds
No full textThe observation of hydrogen peroxide in the interstellar medium represents a remarkable discovery for the astrochemistry community. The prototypical role that this molecule, arguably the simplest chiral molecule, plays in the evolution of life in biospheres, is related to the chirality change transitions associated with the torsional motions around the O - O and the S - S bonds. In this paper, we present an overview on the state-of-art of possible experiments to demonstrate chiral effects discrimination and computational tools applied to peroxides and persulfides

Band Alignment and Electrical Investigations of Ultra-Thin Al2O3 on Si by E-beam Evaporation
No full textThe continuous downscaling leads the search of high-gate dielectrics. The films amorphous in nature offered good mechanical flexibility, smooth surfaces and better uniformity associated with low leakage current density. In this work, 16 nm thick amorphous Al2O3 films on silicon substrate are fabricated by E-beam evaporation. The high value of refractive index (1.76) extracted from ellipsometry analysis directs the deposition of compact film. The AFM analysis reveal a flat surface with small RMS surface roughness 1.5 angstrom. The band gap is extracted from O-1s electron loss spectra and was found 6.7 eV and band alignment of Al2O3/Si is derived from the UPS measurements. The films are incorporated in Metal Insulator -Semiconductor (MIS) capacitor to perform the electrical measurement. The flat band voltage (V-FB), dielectric constant () and oxide trapped charges (Q(ot)) extracted from high frequency (1 MHz) C-V curve are - 0.4 V, 8.4 and 2 x 10(11) cm(-2), respectively. The small flat band voltage - 0.4 V, narrow hysteresis and very little frequency dispersion suggest an exceptional good Al2O3/Si interface with small quantity of trapped charges in the oxide. The leakage current density was 4.27 x 10(-8) A/cm(2) at 1 V. The moderate dielectric constant and low leakage current density with ultra-smooth surface is quite useful towards its application in future CMOS and memory devices
Model based defect characterization in composites
No full textWork is reported on model-based defect characterization in CFRP composites. The work utilizes computational models of the interaction of NDE probing energy fields (ultrasound and thermography), to determine 1) the measured signal dependence on material and defect properties (forward problem), and 2) an assessment of performance-critical defect properties from analysis of measured NDE signals (inverse problem). Work is reported on model implementation for inspection of CFRP laminates containing multi-ply impact-induced delamination, with application in this paper focusing on ultrasound. A companion paper in these proceedings summarizes corresponding activity in thermography. Inversion of ultrasound data is demonstrated showing the quantitative extraction of damage properties.This proceeding may be downloaded for personal use only.

Probing of Barrier Induced Deviations in Current-Voltage Characteristics of Polymer Devices by Impedance Spectroscopy
No full textTemperature dependent current-voltage measurements have been performed on poly(3-methylthiophene) based devices in metal/polymer/metal geometry in temperature range 90-300 K. Space charge limited current (SCLC) controlled by exponentially distributed traps is observed at all the measured temperatures at intermediate voltage range. At higher voltages, trap-free SCLC is observed at 90 K only while slope less than 2 is observed at higher temperatures which is quiet unusual in polymer devices. Impedance measurements were performed at different bias voltages. The unusual behavior observed in current-voltage characteristics is explained by Cole-Cole plot which gives the signature of interface dipole on electrode/polymer interface. Two relaxation mechanisms are obtained from the real part of impedance vs frequency spectra which confirms the interface related phenomena in the devic
Introduction
No full textFirst paragraph: In the Mexican film Cronos (1993), a mysterious device designed to provide its owner with eternal life resurfaces after four hundred years, leaving a trail of destruction in its path. When opened, the device stabs the handler and the incision stimulates youthful vigour and a vampire’s need for blood. Directed by Guillermo del Toro, who would go on to make the Gothic horror films Devil’s Backbone (2001), Pan’s Labyrinth (2006) and the American mainstream vampire superhero action movie Blade II (2002), Cronos is part of a tradition of vampire narratives in the American tropics that stretches from the civatateo of Aztec mythology to the tale of the azeman in Surinam to the oral stories of the peuchen in Chile to the lobisomem of Brazilian folklore to the soucouyant and volant in the Anglophone and Francophone Caribbean. But Cronos is also part of a significant Gothic cinematic tradition in the tropics of the Americas that includes, among many others, vampire films such as Vampiros (2004) by the Puerto Rican director Eduardo Ortíz, Sangre eternal (Eternal Blood, 2002) by Jorge Olguin from Chile, as well as the Columbian films Pura sangre (Pure Blood, 1982) by Luis Ospina and Carne de tu carne (Flesh of Your Flesh, 1983) by Carlos Mayolo. In fact, Mayolo refers to his vampire movie and his haunting work La mansión de Araucaíma (The Manor of Araucaíma 1986) as ‘Gótico tropical’ (tropical Gothic) films that revolve around ‘la estructura del gótico’, a gothic structure in a tropical setting (9)
