Étude pétrographique et géochimique intégrée du charbon et de shale à gaz du bassin Sabinas et de Chihuahua au Nord du Mexique : estimation des ressources en gaz méthane / Petrographic and geochemical study integrated coal and shale gas from Sabinas basin and Chihuahua in northern Mexico : estimation of gas methane resourcesO Burrola, Francisco de la 14 December 2013 (has links)
Une étude de caractérisation intégrée de pétrographie et géochimie organique a été réalisée dans les bassins de Sabinas et Chihuahua au Nord-Est du Mexique. Ces informations ont permis une modélisation numérique de la formation du gaz en considérant la subsidence thermique des charbons et des shales à gaz. Les objectifs de cette thèse sont les suivants: mise en place d'une méthodologie de caractérisation des roches étudiées ; estimation du potentiel générateur de gaz et sa distribution régionale ; estimation des ressources en gaz méthane. Les analyses effectuées sur l'ensemble des échantillons ont permis de caractériser la roche, les kérogènes, les huiles et les gaz. La méthodologie utilisée permet de croiser les informations pétrographiques et géochimiques pour pouvoir analyser le système pétrolier par modélisation numérique. Les analyses réalisées sont: réflectance% Ro, analyse élémentaire et immédiate, Rock Eval6 ® (Bulk Rock), [delta]13C, [delta]D, (gaz de charbon), microscopie électronique à balayage, analyse d'images, analyse des macéraux et inclusions fluides. Un programme informatique a été construit afin de croiser l'information des analyses des échantillons avec celle des expériences de maturation artificielle en laboratoire. Cette démarche nous à permis d'estimer les ressources en gaz méthane à la fois généré par les charbons et les shales gaz. La méthodologie utilisée pour l'étude des kérogènes et des gaz dans les deux bassins est à notre avis la plus appropriée pour répondre aux objectifs proposés dans ce travail de thèse. Celle-ci permet de caractériser l'évolution thermique des charbons, shales gas (gaz de schiste), et roches mères pétrolières / This comprehensive characterization study was performed using organic petrology and geochemistry conducted in the Sabinas basin and Chihuahua in northern Mexico. This information allowed a numerical modeling of gas formation, considering the thermal subsidence of coal and carbonaceous shales.The objectives of this thesis are: establish a characterization methodology for the studied rocks ; estimate potential gas generator and its regional distribution ; estimate the methane gas resources. For the development of this project, we conducted an intensive campaign representative sampling of coal, carbonaceous shales and coal gas "in situ". For the Sabinas basin were studied 97 samples and 114 samples in the basin of Chihuahua. The analyses carried out that were used on the samples analyzed allowed to characterize the kerogen and gas. The methodology used to cross petrographic and geochemical information to analyze the petroleum system by numerical modeling. Analyses were: Petrographic, reflectance %Ro, elemental analysis and immediate, Rock Eval6 ® (Bulk rock), isotopic analysis, [delta]13C, [delta]D, (coal gas), scanning electron microscopy, image analysis and analysis of macerals fluid inclusions. The analyzes that were used on the samples allowed to characterize the sample, the kerogen and gas. The methodology used to cross petrographic and geochemical information for analyze the oil system by numerical modeling. Analyses were: Petrographic, reflectance% Ro, elemental analysis and immediate, Rock Eval6 ® (Bulk rock), isotopic analysis, d13C, dD, (coal gas), scanning electron microscopy, image analysis and analysis of macerals fluid inclusions. A computer program was constructed to cross the information with the analysis of samples of artificial maturation experiments in the laboratory. This approach allowed estimation of methane gas resources generated by coal and carbonaceous shales. [...] In conclusion, between the two basins studied, the Sabinas basin, generates more gas for industrial exploitation. However, the rocks of the basin of Chihuahua unconventional types (shale gas) show good potential for hydrocarbon generation. The methodology used for the study of kerogen and gas in the two basins is in our opinion the most appropriate to meet the objectives proposed in this thesis. This allows to characterize the thermal evolution of coal, carbonaceous shale (shale gas), coal gas and hydrocarbon source rocks

Justicia en reforma : a diagnostic of Mexico's criminal procedure reform in early-implementer jurisdictionsNichols, Denton Patrick 07 July 2011 (has links)
Until recently, Mexico’s criminal court system systematically failed to observe the human rights of defendants, leading to widespread criticisms about the integrity of the system and the vulnerability of defendants to unconscionable judicial practices. Intending to remedy those deficiencies, several Mexican states have proceeded to transition from a semi-inquisitorial criminal procedure to an American-style adversarial one. Because of a 2008 reform to the national constitution, all Mexican states must adopt such criminal procedure reforms by 2016. In theory, these reforms should result in fewer overall cases, a reduced reliance on pre-trial detentions, and more dismissals of cases and acquittals. This thesis uses data collected by Mexico’s official statistical agency, INEGI, to test these hypotheses in judicial districts in four states: Oaxaca, Chihuahua, Morelos, and Zacatecas. While far fewer criminal cases are being brought in early-implementer districts that have transitioned to the new criminal procedures, the results on other statistical indicators are mixed. Nonetheless, the balance of evidence suggests that the reformed procedures are more likely to be fair to defendants and reduce overall wrongful convictions. / text

Espacio público para todos: using purpose-oriented amenities to enhance childhood development in Mexican public spacesEwald, Lauren January 1900 (has links)
Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Huston Gibson / The issues infested in urban slum communities are many, of which I had no problem indentifying a dilemma specific to my interests in landscape architecture and socially equitable places. However, sustainable solutions specific to these dynamic urban forms and communities are unfamiliar academic territory. Extreme levels of poverty fostered in these communities cause deficiencies in a child’s development, who are often without access to a formal, structured education system (UNDP, 1999). Public spaces are particularly stimulating environments for youth learning and development, but most urban environments in shanty towns host a milieu of violence and crime, making most public streets and vacant lots unsafe. These conditions are ripe for visionary designers to intervene, improving the physical aspects of urban public spaces and specifically bettering the quality of life for children living in these communities.
Answering this question required literature research and precedent studies, which was important for developing a thorough understanding of developmental theory as it relates to socio-economically disadvantaged children. By focusing my studies on public spaces in the neighborhood Vistas del Cerro Grande in Chihuahua, México, I began to understand the cultural idiosyncrasies specific to people living in urban shantytowns. Data collected from the neighborhood via surveys, interviews, community meetings, and an auto-ethnographic video study with fifth and sixth grade students provided an introduction to the community and the larger themes and objectives for future public space design. Visiting comparable communities in México City, México deepened my understanding as I was able to observe the daily lives of México City residents with diverse socio-economic statuses, hear their individual perspectives on the history and cultures, and relate to their frustrations with current political, economic, and societal systems.
The methodologies described above culminated in a design typology specific to Vistas del Cerro Grande, consisting of public streets, pedestrian access ways, plazas, and vacant lots. These types form the backbone of my research report, which represents an evidence-based design palette of purpose-oriented amenities for positive childhood development in shanty town public spaces. The typology caters to the specific needs of the Vistas del Cerro Grande community, as identified in the research.

Schooling in times of dystopia : empowering education for Juárez womenCervantes Soon, Claudia Garbiela 22 June 2011 (has links)
Young women in Ciudad Juárez, Mexico are coming of age in an era of feminicides, drug wars, impunity, and fear. This ethnographic study examines the ways in which Preparatoria Altavista, a public high school, in one of the most marginalized areas of Juárez, attempts to empower subaltern young women through its critical and social justice philosophy of education.
The study draws from critical pedagogy, socio-cultural theory, and feminist scholarship to offer a unique analysis of how hegemonic ideas are resisted and/or inscribed pedagogically, politically, and institutionally at Altavista. Secondly, the study examines how the school’s constructions of democratic and social justice education interact with the current dystopic context of Juárez and discourses about Juárez women to provide a framework with which a group of young women author their identities and practice forms of resistance.
The ethnographic fieldwork took place in the 2009-2010 academic year. The methods included unstructured ethnographic interviews with teachers, administrators, and numerous students, as well as semi-structured interviews and an auto-photography technique with nine girls.
The study identifies three interrelated aspects that characterize the transformative pedagogy of Preparatoria Altavista: freedom and autonomy, authentic caring relationships, and the cultivation of critical discourse and activism. Together, these core values promote the school’s ultimate goal for its students – autogestión, or the ability to self-author empowered identities; read their world; and initiate and develop socially transformative projects. Considering the school’s context, as well as the many challenges inherent in the dystopic Juárez of today, the study also identifies a typology of four different paths to the girls’ identity and agency development: the Redirectors, the Reinventors, the Redefiners, and the Refugees. This typology is based on various ways and degrees to which the young women in this study authored the self as they negotiated the messages from the multiple figured worlds that they inhabit.
The study seeks to counter sensationalist, criminalizing, and dooming narratives about Juárez youth, as well as stereotypical and objectifying depictions of Juárez women by offering a nuanced analysis of their experiences, perspectives, identities, and forms of agency. The study also seeks to offer a language of possibility and hope for urban schools and contexts of civil unrest through critical pedagogy. / text

Bioarchaeology of violence and site abandonment at Casas Grandes, Chihuahua, MexicoCasserino, Christopher Michael, 1967- 06 1900 (has links)
xvii, 133 p. : ill., maps. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number. / The objective of this dissertation is to address violence at the archaeological site of Casas Grandes (Paquimé) in northwest Chihuahua, Mexico. The reasons for the abandonment of Paquimé are uncertain. The prevailing theory claims this geographic area endured centuries of warfare, ritual sacrifice, and at least one massacre; this theory is supported by numerous unburied bodies recovered at the site. These assertions of violence have never been corroborated by osteological data.
Data were collected from a sample of Medio period (A.D. 1200-1450) human skeletal remains recovered from the 1958-1961 excavations at Casas Grandes. These data were synthesized with accelerator mass spectrometry radiocarbon dates, fluoride ion dates, population demographics, and burial context. Frequencies of ante-, peri-, and postmortem trauma were compared to other studies from the Old and New Worlds.
I argue that warfare was not endemic to this region and that a massacre did not occur. Moreover, cannibalism and probably human sacrifice were practiced. I assert that these activities may have been related to the proliferation of the Mesoamerican ballgame in the American Southwest and to Paquimé's role as the distribution center of the region's ritual and exotic goods. This dissertation underscores the importance of including skeletal analysis with other lines of archaeological inquiry when answering questions about human behavior. / Committee in charge: John Lukacs, Chairperson, Anthropology;

Complementary Dualities: The Significance of East/West Architectural Difference in PaquiméHughes, Delain 08 1900 (has links)
This thesis provides the first formal and phenomenological analysis of the architecture in Paquimé, otherwise known as Casas Grandes, Chihuahua, Mexico. The eastern and western halves of the city are divided by a stone wall and reservoirs. The monuments on the east are rectilinear, puddled adobe structures used primarily for domestic and manufacturing purposes. The buildings on the west, on the other hand, are open earth mounds lined in stone for public displays. This thesis analyzes each building individually, the relationship of the structures to one another, and the entire layout of Paquimé in order to better understand Paquimian visual culture.

Wildfire Assessment Using FARSITE Fire Modeling: A Case Study in the Chihuahua Desert of MexicoBrakeall, John 02 July 2013 (has links)
The Chihuahua desert is one of the most biologically diverse ecosystems in the world, but suffers serious degradation because of changes in fire regimes resulting in large catastrophic fires. My study was conducted in the Sierra La Mojonera (SLM) natural protected area in Mexico. The purpose of this study was to implement the use of FARSITE fire modeling as a fire management tool to develop an integrated fire management plan at SLM.
Firebreaks proved to detain 100% of wildfire outbreaks. The rosetophilous scrub experienced the fastest rate of fire spread and lowland creosote bush scrub experienced the slowest rate of fire spread. March experienced the fastest rate of fire spread, while September experienced the slowest rate of fire spread. The results of my study provide a tool for wildfire management through the use geospatial technologies and, in particular, FARSITE fire modeling in SLM and Mexico.

Lithic Production at the Mesilla Phase Placitas Arroyo Site Complex Doña Ana County, New MexicoYounger, Alexandra Carla 08 1900 (has links)
This study of lithic analysis shifts attention from typological studies to explicitly behavioral analyses, complimenting studies of both intrasite and intersite patterns of variability and change. Analysis of several assemblages from the Placitas Arroyo site complex reveals changing patterns of raw material procurement and selection, core reduction strategies, as well as tool production and discard. The most striking result thus far is the quite uniform emphasis on flake production from well-prepared cores, and the near absence of manufacture or maintenance of bifacial tools, especially projectile points. Associated with common ground stone artifacts, the flaked stone materials may well represent intensive food processing. Regardless, the technological patterns being revealed by this approach illustrate a productive new means to gain insights into changing behaviors in the Jornada Mogollon cultural tradition.
