Offshore wind energy climate projection using UPSCALE climate data under the RCP8.5 emission scenario

MARKUS SEBASTIAN GROSS (2016, [Artículo])

In previous work, the authors demonstrated how data from climate simulations can be utilized to estimate regional wind power densities. In particular, it was shown that the quality of wind power densities, estimated from the UPSCALE global dataset in offshore regions of Mexico, compared well with regional high resolution studies. Additionally, a link between surface temperature and moist air density in the estimates was presented. UPSCALE is an acronym for UK on PRACE (the Partnership for Advanced Computing in Europe)-weather-resolving Simulations of Climate for globAL Environmental risk. The UPSCALE experiment was performed in 2012 by NCAS (National Centre for Atmospheric Science)- Climate, at the University of Reading and the UK Met Office Hadley Centre. The study included a 25.6-year, five-member ensemble simulation of the HadGEM3 global atmosphere, at 25km resolution for present climate conditions. The initial conditions for the ensemble runs were taken from consecutive days of a test configuration. In the present paper, the emphasis is placed on the single climate run for a potential future climate scenario in the UPSCALE experiment dataset, using the Representation Concentrations Pathways (RCP) 8.5 climate change scenario. Firstly, some tests were performed to ensure that the results using only one instantiation of the current climate dataset are as robust as possible within the constraints of the available data. In order to achieve this, an artificial time series over a longer sampling period was created. Then, it was shown that these longer time series provided almost the same results than the short ones, thus leading to the argument that the short time series is sufficient to capture the climate. Finally, with the confidence that one instantiation is sufficient, the future climate dataset was analysed to provide, for the first time, a projection of future changes in wind power resources using the UPSCALE dataset. It is hoped that this, in turn, will provide some guidance for wind power developers and policy makers to prepare and adapt for climate change impacts on wind energy production. Although offshore locations around Mexico were used as a case study, the dataset is global and hence the methodology presented can be readily applied at any desired location. © Copyright 2016 Gross, Magar.

“Mexico half way of making”: Carlos Chávez and the foundation of the National Institute of Fine Arts (INBA) (1945-1947)

Ana Garduño (2023, [Artículo, Artículo])

I am focusing on the interaction between a cultural agent, Carlos Chávez, and the government elite, related to the circumstances of the enunciation of a public and official organism, INBA (The National Institute of Fine Arts), because I assume that political relations are fundamental to understand a process that endorsed the official culture as an appendage of politics. In spite of its relevance, this subject has not been studied. Based on archival documentation (at the National Archive of Mexico and the archive of INBA) I am examining the cultural policies derived from the foundation of INBA. Due to the current pandemic situation, it was not possible to consult other documental sources. I am formulating that the concept of “high culture” was at the core of a wider conflict between governmental interests and those of representative social actors, and I conclude that this obstacle would have conferred a major political and symbolical importance to the Institute, and consequently, would restrict its budget.

Hot Extremes and Climatological Drought Indicators in the Transitional Semiarid-Subtropical Region of Sinaloa, Northwest Mexico

OMAR LLANES CARDENAS OSCAR GERARDO GUTIERREZ RUACHO Iván Hernández Romano ENRIQUE TROYO DIEGUEZ (2022, [Artículo])

"The main goal of this study was to explore the historical and recent spatial concurrence between the frequency (F), duration (D) and intensity (I) of hot extremes (HEs) and the frequency and evolution of meteorological drought in the region of Sinaloa. Based on the values of daily maximum temperatura (Tmax) and precipitation obtained from CLImate COMputing for the interval April–October of a historical period (1963–2000) and a recent period (1982–2014), the HE and the standardized precipitation index (SPI) were calculated on one-month (SPI-1) and four-month (SPI-4) timescales. Spearman rank correlation coefficients (Sr) were used to obtain the significant concurrences (SCs) between HEs and SPI-1, and HEs and SPI-4. El Quelite weather station showed the highest historical SCs between HEs and SPI-1 (−0.66≤Sr≤−0.57). Jaina is the only station that showed SCs with all four indicators of HEs and SPI-4 (−0.47≤Sr≤−0.34). In this study, the concurrence between HEs and SPI-1, and HEs and SPI-4 was determined for the first time. These are phenomena that can decrease the crop yield, particularly for rainfed crops such as maize, sesame and sorghum in the region commonly known as “the breadbasket of Mexico."

Andres Alejandro Ojanguren Affilastro (2017, [Artículo])

Tityus curupi n. sp., belonging to the bolivianus complex, is described from the biogeographically distinct area of Paraje Tres Cerros in north-eastern Argentina. We also present a molecular species delimitation analysis between Tityus curupi n. sp. and its sister species Tityus uruguayensis Borelli 1901 to confirm species integrity. Furthermore, a cytogenetic analysis is presented for these two species which contain different multivalent associations in meiosis, as a consequence of chromosome rearrangements, and the highest chromosome numbers in the genus. © 2017 Ojanguren-Affilastro et al.

Rapid effects of marine reserves via larval dispersal

Richard Cudney Bueno (2009, [Artículo])

Marine reserves have been advocated worldwide as conservation and fishery management tools. It is argued that they can protect ecosystems and also benefit fisheries via density-dependent spillover of adults and enhanced larval dispersal into fishing areas. However, while evidence has shown that marine reserves can meet conservation targets, their effects on fisheries are less understood. In particular, the basic question of if and over what temporal and spatial scales reserves can benefit fished populations via larval dispersal remains unanswered. We tested predictions of a larval transport model for a marine reserve network in the Gulf of California, Mexico, via field oceanography and repeated density counts of recently settled juvenile commercial mollusks before and after reserve establishment. We show that local retention of larvae within a reserve network can take place with enhanced, but spatially-explicit, recruitment to local fisheries. Enhancement occurred rapidly (2 yrs), with up to a three-fold increase in density of juveniles found in fished areas at the downstream edge of the reserve network, but other fishing areas within the network were unaffected. These findings were consistent with our model predictions. Our findings underscore the potential benefits of protecting larval sources and show that enhancement in recruitment can be manifested rapidly. However, benefits can be markedly variable within a local seascape. Hence, effects of marine reserve networks, positive or negative, may be overlooked when only focusing on overall responses and not considering finer spatially-explicit responses within a reserve network and its adjacent fishing grounds. Our results therefore call for future research on marine reserves that addresses this variability in order to help frame appropriate scenarios for the spatial management scales of interest. © 2009 Cudney-Bueno et al.

A simple extension to the CMASA method for the prediction of catalytic residues in the presence of single point mutations

David Israel Flores Granados (2014, [Artículo])

The automatic identification of catalytic residues still remains an important challenge in structural bioinformatics. Sequence-based methods are good alternatives when the query shares a high percentage of identity with a well-annotated enzyme. However, when the homology is not apparent, which occurs with many structures from the structural genome initiative, structural information should be exploited. A local structural comparison is preferred to a global structural comparison when predicting functional residues. CMASA is a recently proposed method for predicting catalytic residues based on a local structure comparison. The method achieves high accuracy and a high value for the Matthews correlation coefficient. However, point substitutions or a lack of relevant data strongly affect the performance of the method. In the present study, we propose a simple extension to the CMASA method to overcome this difficulty. Extensive computational experiments are shown as proof of concept instances, as well as for a few real cases. The results show that the extension performs well when the catalytic site contains mutated residues or when some residues are missing. The proposed modification could correctly predict the catalytic residues of a mutant thymidylate synthase, 1EVF. It also successfully predicted the catalytic residues for 3HRC despite the lack of information for a relevant side chain atom in the PDB file. © 2014 Flores et al.

Desarrollo de interfaces de electrodos para la detección electroquímica de Bisfenol A: Estudio teórico

JAZMIN DELGADO AVILEZ (2023, [Tesis de maestría])

El bisfenol A (BPA), es un contaminante de origen industrial presente en efluentes y

aguas naturales, que representa un alto riesgo para el entorno ambiental y para la salud humana debido a su inherente toxicidad y su limitada capacidad de degradación. En este contexto, los sensores electroquímicos, generalmente basados en electrodos de carbono, son herramientas fundamentales con el propósito de detectar y cuantificar esta molécula. Sin embargo, estos dispositivos enfrentan desafíos sustanciales derivados de la inactivación electroquímica, un fenómeno atribuido a la formación de una capa aislante o polimerización durante el proceso de detección. La descripción de los mecanismos de reacción BPA/superficie del electrodo puede ser útil para identificar los sitios activos y contribuir a la elucidación del proceso de polimerización.

En esta investigación, se implementó un estudio teórico mediante Teoría de Funcionales de la Densidad (DFT) con el propósito de analizar con profundidad las interacciones entre el BPA en sus diversos estados de oxidación: oxidada (O), reducida (R) y monoprotonada (r*) y materiales de carbono. A tal efecto, se empleó el grafeno funcionalizado (plano basal, borde tipo silla y zigzag) como modelo representativo de la superficie del electrodo. Finalmente se evalúan las posibilidades de la dimerización del BPA o polimerización sobre varios grupos funcionales. El objetivo principal radica en la detección de grupos funcionales específicos que puedan inducir procesos secundarios, los cuales actúan como obstáculos para la eficaz detección electroquímica del BPA. La información resultante se instituye como un recurso valioso con miras al diseño y la optimización de sensores electroquímicos con un desempeño más robusto y sofisticado.

A continuación, se detalla la sinopsis general de este trabajo describiendo cada capítulo y las etapas involucradas en el estudio del modelo teórico de DFT para el sistema de reacción BPA/superficie del electrodo.

Capítulo 1. Estado del arte tanto de los usos industriales como las implicaciones

ambientales asociadas al Bisfenol A. Una de las problemáticas que se destacan es la necesidad de una detección precisa de esta molécula mediante sensores electroquímicos cuya limitación es la inactivación que presentan. También se describe la justificación del trabajo, así como el uso del modelo computacional, además de los objetivos y la hipótesis del mismo.

Capítulo 2. Descripción de los fundamentos teóricos basados en primeros principios, de la Teoría de Funcionales de la Densidad (DFT), con un enfoque especial en las aproximaciones para desarrollar modelos representativos que optimicen el tiempo de cálculo. Además, se detallan las características de la estructura y la superficie de los materiales de carbono considerados en el proceso de modelado.

Capítulo 3. Detalle del proceso de construcción del modelo de superficie para el estudio de las interacciones BPA/superficie del electrodo, donde se empleó el modelo del plano basal,así como los bordes tipo silla y zigzag del grafeno, con funcionalizaciones que incluyen COOH, OH, éter, epóxido, cetona y terminaciones de hidrógeno.

Bisphenol A (BPA) is a contaminant of industrial origin present in effluents and natural waters. It represents a high environmental and human health risk due to its inherent toxicity and limited degradation capacity. In this context, electrochemical sensors, generally based on carbon electrodes, are fundamental to detecting and quantifying this molecule. However, these devices face substantial challenges from electrochemical inactivation, a phenomenon attributed to forming an insulating layer or polymerization during the sensing process. The description of the BPA/electrode surface reaction mechanisms can be helpful to identify the active sites and contribute to the elucidation of the polymerization process.

In this research, a theoretical study was implemented using Density Functional Theory (DFT) to analyze in depth the interactions between BPA in its various oxidation states: oxidized (O), reduced (R), and monoprotonated (r*) and carbon materials. For this purpose, functionalized graphene (basal plane, saddle edge, and zigzag) was used as a representative model of the electrode surface. Finally, the possibilities of BPA dimerization or polymerization on various functional groups are evaluated. The main objective is detecting specific functional groups that can induce secondary processes, which act as obstacles to the effective electrochemical detection of BPA. The resulting information is a valuable resource for designing and optimizing electrochemical sensors with more robust and sophisticated performance.

The general synopsis of this work is detailed below, describing each chapter and the

stages involved in the study of the theoretical DFT model for the BPA/electrode surface reaction system.

Chapter 1. State of the art of industrial uses and the environmental implications associated with Bisphenol A. One of the problems that stands out is the need for precise detection of this molecule using electrochemical sensors, whose limitation is the inactivation they present. The justification of the work is also described, as well as the use of the computational model, in addition to its objectives and hypothesis.

Chapter 2. Description of the theoretical foundations based on first principles of Density Functional Theory (DFT), focusing on approaches to develop representative models that optimize calculation time. Additionally, the structure and surface characteristics of the carbon materials considered in the modeling process are detailed.

Chapter 3. Detail of the construction process of the surface model for the study of BPA/electrode surface interactions, where the basal plane model was used, as well as the chair- type and zigzag edges of graphene, with functionalizations that include COOH, OH, ether, epoxide, ketone, and hydrogen endings.

La expresión del inconsciente arquetípico a través del cuerpo bailado y esculpido en el teatro mitológico afrocubano de Eugenio Hernández Espinosa

Rosana Herrero-Martin (2023, [Capítulo de libro])

En este artículo se analizarán desde una perspectiva jungiana y holística una selección de momentos dancísticos y escultóricos en tres obras dramáticas del corpus teatral mitológico del autor cubano Eugenio Hernández Espinosa (María Antonia, 1967; Odebí, el cazador, 1980, y El Elegido, 1995), protagonizadas en los tres casos por diferentes orishas, nombre con el que se conocen popularmente en Cuba —concretamente en la tradición cultural y espiritual yoruba de la isla— a las manifestaciones antropomórficas, físicas, vivenciales y sobrenaturales de la divinidad. El paradigma de análisis aplicado es principalmente el del pensamiento integral de Ken Wilber, por el cual cuerpo-mente-psique-divinidad se conciben como un todo interconectado, integrado y resonador dentro del proceso de individualización de la persona, siendo el cuerpo el vehículo, el espejo, la palanca y la puerta de acceso, es decir, siendo el cuerpo el que refleja, activa y abre el resto de las dimensiones.

In this article, a selection of dance and sculptural moments in three dramatic works from the mythological theatrical corpus of Cuban author Eugenio Hernández Espinosa will be analyzed from a Jungian and holistic perspective (María Antonia, 1967; Odebí, the Hunter, 1980, and The Chosen, 1995). All three plays star a selection of Orishas, the name by which the anthropomorphic, physical, experiential and supernatural manifestations of divinity are popularly known in Cuba — specifically in the island’s Yoruba cultural and spiritual tradition. The analytical paradigm to be applied is mainly Ken Wilber’s integral thought, by which body-mind-psyche-divinity are conceived as an interconnected, integrated and resonating whole within the person’s individualization process, the body being the vehicle, the mirror, the lever and the access door, that is, the body being the one which reflects, activates and opens the rest of the dimensions.

Evaluación del aporte hidrológico superficial en el sistema de bloque de montaña de la subcuenca Ojos Negros

Surface hydrological contribution evaluation in the mountain block system of the Ojos Negros subbasin

Ricardo Adolfo Hidalgo Rodríguez (2023, [Tesis de maestría])

Este trabajo se realizó en la sección de la subcuenca Ojos Negros, sobre el bloque de montaña de la Sierra de Juárez (denominado Sistema de Bloque de Montaña de la Subcuenca Ojos Negros, SBMON), en el estado de Baja California, México. Se llevó a cabo un modelado hidrológico del escurrimiento en el periodo 1981-2020 para cuantificar el aporte hidrológico de salida hacia el Valle de Ojos Negros. En cumplimiento del objetivo, se diseñó una base de datos meteorológicos compuesta por los registros diarios de las estaciones meteorológicas en la región y del modelo de forzamiento de superficie NLDAS2. Se recopiló un conjunto de información edafológica, forestal, geológica, satelital y topográfica dentro del área de estudio. Con la información recolectada, se elaboraron dos modelos de escurrimiento empleando el método de las curvas numeradas (CN) del Departamento de Agricultura de los Estados Unidos (USDA). Los modelos fueron ajustados con los valores de sustracción inicial, Ia, de 0.2 (modelo A) y 0.05 (modelo B). Las series generadas se compararon con los resultados del modelo GCN250, basado en los datos edafológicos y forestales de la Agencia Espacial Europea (ESA). A nivel regional, se observó un aporte de escurrimiento anual de 9.2 Mm3 (GCN250), 10.9 Mm3 (modelo A) y 4.7 Mm3 (modelo B). La sección oriental del SBMON mostró el mayor potencial de infiltración, pero también fue la zona con mayor producción de escurrimiento en todos los modelos. Desde la perspectiva estacional, se identificaron periodos donde los escurrimientos formados a partir de las lluvias en verano superaron a los generados en la temporada invernal. Con base a los resultados obtenidos, el aporte de escurrimiento dentro del SBMON es significativa, no obstante, los procesos de escurrimiento subsuperficial y subterráneo pueden tener un papel todavía más importante en la recarga hacia el Valle de Ojos Negros. Se recomienda dar seguimiento a la variación del contenido de humedad en los suelos del SBMON, a los patrones anuales y estacionales de precipitación, así como la contribución hídrica del derretimiento de la nieve en la Sierra de Juárez.

This work was realized in the section of the Ojos Negros sub-basin, on the Sierra de Juárez mountain block (denominated Mountain Block System of the Ojos Negros Sub-Basin, SBMON), in the state of Baja California, Mexico. A hydrological runoff modeling was carried out for the period 1981-2020 to quantify the output hydrological contribution toward the Ojos Negros Valley. In compliance with the objective, a meteorological database consisting of the daily records of the meteorological stations and the NLDAS-2 surface forcing model was designed. A set of edaphological, forestry, geological, satellite, and topographical information was collected within the study area. Based on the collected information, two runoff models were developed using the Curve Number (CN) method from the United States Department of Agriculture (USDA). The models were adjusted with the initial subtraction values, Ia, of 0.2 (model A) and 0.05 (model B). The generated series were compared with the results of the GCN250 model, based on soil and forestry data from the European Space Agency (ESA). Regionally, an annual runoff contribution of 9.2 Mm3 (GCN250), 10.9 Mm3 (model A), and 4.7 Mm3 (model B) was observed. The eastern section of the SBMON showed the highest infiltration potential, but it was also the area with the highest runoff production in all models. From the seasonal perspective, periods were identified where the runoff formed from summer rains exceeded that generated in the winter season. Based on the results obtained, the runoff contribution within the SBMON is significant, however, the subsurface and underground runoff processes may have an even more key role in the recharge toward the Ojos Negros Valley. It is recommended to monitor the variation of the moisture content in the SBMON soils, the annual and seasonal patterns of precipitation, as well as the water contribution from the snow melting in the Sierra de Juárez.
