Derrotas y Traiciones o la Visión Histórica en Los Recuerdos del Porvenir de Elena Garro
Gerardo Gomez Michel(Michel, Gerardo G.) 한국라틴아메리카학회 2018 라틴아메리카연구 Vol.31 No.1
In Elena Garro’s novel Los recuerdos del porvenir, historical pessimism is a central subject. Not only because the plural narrator, the town of Ixtepec itself, sustains a vision that refers to the fall of the social pact it was built upon, but the novel also shows how the collapse is intertwined with a series of historicaldefeats and betrayals that in the end, emphasize the pessimistic meaning of the allegorical suspended time that opens and closes the story. The plot of the novel advances by constructing a panoramic vision of what this violent period of the Cristiada would mean for modern Mexico. Following this order of ideas, in this work we will review the defeats and betrayals that appear in the novel in order to underline the historical vision suggested by the symbolic petrification of Ixtepec, particularly pointing out how the Cristero conflict enables the novel to construct a discourse that points to a wide defeat of the Nation.

This article reviews the historical processes in Mayan language and literature of Yucatan since the time of the Conquest to the present day. Analyzing key moments of social, cultural and political confrontation between the Maya people and powers external to their community, I highlight how the Mayan language and literature circulated from an evangelizing utilitarianism to a nationalistic assimilation, and how in both cases the ultimate goal was the ethnic-cultural disintegration to subsume the Mayan people to the order imposed by the imperial and national regimes, respectively. This tendency dialectically provoked a reaction in the subjugated community, which sees indigenous language as a vehicle of political and cultural resistance. Finally, the article includes a review of the current resurgence of Maya writing that seeks to rebuild their world view and recover their literary language.
Experimental vs. theoretical out-of-plane seismic response of URM infill walls in RC frames
Gerardo M. Verderame,Paolo Ricci,Mariano Di Domenico 국제구조공학회 2019 Structural Engineering and Mechanics, An Int'l Jou Vol.69 No.6
In recent years, interest is growing in the engineering community on the experimental assessment and the theoretical prediction of the out-of-plane (OOP) seismic response of unreinforced masonry (URM) infills, which are widespread in Reinforced Concrete (RC) buildings in Europe and in the Mediterranean area. In the literature, some mechanical-based models for the prediction of the entire OOP force-displacement response have been formulated and proposed. However, the small number of experimental tests currently available has not allowed, up to current times, a robust and reliable evaluation of the predictive capacity of such response models. To enrich the currently available experimental database, six pure OOP tests on URM infills in RC frames were carried out at the Department of Structures for Engineering and Architecture of the University of Naples Federico II. Test specimens were built with the same materials and were different only for the thickness of the infill walls and for the number of their edges mortared to the confining elements of the RC frames. In this paper, the results of these experimental tests are briefly recalled. The main aim of this study is comparing the experimental response of test specimens with the prediction of mechanical models presented in the literature, in order to assess their effectiveness and contribute to the definition of a robust and reliable model for the evaluation of the OOP seismic response of URM infill walls.

Background: The effort to detect lung cancer in ever-earlier stages leads to the identification of an increasing number of patients without preoperative histological diagnosis. The aim of this study is to determine the prevalence and characteristics of benign lesions excised in the context of lung cancer surgery. Methods: We retrospectively analyzed data from 125 surgical procedures. We compared the preoperative clinical or cyto-histological diagnosis with the surgical-pathologic diagnosis in order to identify the percentage of benign lesions excised. Furthermore, other parameters were analyzed, such as age, sex, tumor size, the presence of calcification, and the type of surgery according to subgroup. Results: Of the 125 patients included in the study, 63 (50.4%) had a preoperative histological diagnosis of malignancy, corresponding to 56 cases (44.8%) of primary lung cancer and 7 cases (5.6%) of metastases. The 62 (49.6%) remaining cases without preoperative histological diagnosis were divided among 50 (40%) solitary pulmonary nodules and 12 (9.6%) pulmonary masses. According to the postoperative pathologic examination, we identified 12 (9.6%) benign lesions excised during lung cancer surgery. There were no statistically significant differences by subgroups with respect to age or sex. We found statistically significant evidence regarding the size and wedge resection as the surgical technique of choice for this type of benign lesion. Conclusion: Our study obtained results similar to those published by other groups regarding the resection of benign lesions in lung cancer surgery. This percentage could be a quality management index of indeterminate lung lesions.
Adaptive Nonlinear Control of Induction Motor

This work addresses the problem of controlling a rigid arm (one degree of freedom robot manipulator) directly driven by an induction motor. A Lyapunov-based adaptive nonlinear controller is designed. The developed controller compensates for parametric uncertainty associated with the resistance of the rotor windings and it is capable to track asymptotically a trajectory for an angular position keeping all the internal signals bounded and guarantees the asymptotical stability of the system. Simulations are presented to illustrate the performance of this controller.
Output Feedback Control for a Quadrotor Aircraft Using an Adaptive High Gain Observer
Gerardo Flores,V. González-Huitron,A. E. Rodríguez-Mata 제어·로봇·시스템학회 2020 International Journal of Control, Automation, and Vol.18 No.6
This paper addresses the problem of quadrotor control under unknown and time-varying disturbances. It is assumed that such disturbances affect the entire quadrotor’s dynamics, i.e., in attitude and position. To stabilize the quadrotor, we propose an output-feedback control approach, in which we implement a Backstepping control together with an Adaptive High Gain Observer to estimate disturbances. The stability of the closed-loop system is proved via the Lyapunov theory. Furthermore, the effectiveness of the methodology is illustrated through numerical simulations and experiments.

Furfural (FUR) was produced from xylose using a biphasic batch reaction system. Water-immiscibleorganic solvents such as isophorone, 2-methyltetrahydrofuran (2-MTHF) and cyclopentyl methyl ether(CPME) were used to promptly extract FUR from the aqueous phase in order to avoid the degradation tohumins as largely as possible. The effect of time, temperature, organic solvent and organic-to-aqueousratio on xylose conversion and FUR yield were investigated in auto-catalyzed conditions. Experiments atthree temperatures (170, 190 and 210 C) were carried out in a stirred microwave-assisted batch reactor,which established the optimal conditions for achieving the highest FUR yield. The maximum FUR yieldsfrom xylose were 78 mol% when using CPME, 48 mol% using isophorone and 71 mol% in the case of 2-MTHF at an aqueous to organic phase ratio of 1:1 (v/v). Birch hydrolysate was also used to show the highfurfural yield that can be obtained in the biphasic system under optimized conditions. The present studysuggests that CPME can be used as a green and efficient extraction solvent for the conversion of xyloseinto furfural without salt addition.

The purposes of the study were to (1) translate the Mindful Awareness Attention Scale (MAAS) (Brown & Ryan, 2003) into Spanish and (2) make adjustments for its application to research in exercise psychology, sport and health. For the translation and transcultural validation, the Spanish version (T4) of the MAAS scale was reviewed by 100 advanced students and professors of Physical Education of the Universidad de Costa Rica. Next, T4 and the original English MAAS were completed by 58 students of the Master`s program in Translation of the Universidad Nacional (Costa Rica). The scales were randomly applied at the beginning and at the end of a three-hour class. Internal consistency measured by Cronbach`s alpha coefficient was adequate (a=0.88 T4 and α=0.84 original). Scores from the two versions were significantly correlated (r=0.94; p<0.01) and were not different (t=0.73; p>0.05). Thus it was found that the Spanish version of the MAAS is sufficiently valid and reliable to be implemented in research in exercise psychology, sports and health. Further studies must test construct validity of the Spanish version of the MAAS.
Los Días de la Fiebre de Andrés Felipe Solano: De la Crisis Ontológica a la Realidad Cíborg
Gerardo Gomez Michel,Sebastian Patron Saade 한국라틴아메리카학회 2021 라틴아메리카연구 Vol.34 No.2
In Los días de la fiebre, the Colombian writer Andres Felipe Solano recounts his experience in South Korea during the first three months of the pandemic, in 2020. From February to April, Solano describes his personal feelings, as well as his impressions regarding the changes that viral pandemic has introduced in the habits of the inhabitants of this East Asian country. Like other contemporary writers and thinkers who have written about the pandemic and the new normality that it has ushered in, Solano’s narrator uses the current circumstances to reflect on the growing tension between the right to privacy and state intervention, the new challenges imposed by stricter social distancing and isolation rules, and the collapse of Korea’s consumer society, and the collapse of capitalism overall. Beyond these topics, however, Los días de la fiebre is a book in which Solano explores and erases the limits between mind, body and machines, and between living and inanimate beings underlining the risks of post-humanism and a cyborg reality . The virus’s constant threat and the technology deployed to facilitate its detection and prevent its spread lead Solano to modify his self-image and to question both the autonomy and rationality on which rest many of the fantasies of modern man’s domination, and the ontological hierarchies through which this subject has organized his surroundings which are now in crisis.
