In January of 2000, the authors of this article made a ten-day field trip along Mexico's Veracruz to Mexico City corridor, with notebooks, detailed maps, and digital camera in hand. This was all in support of their recent experience in teaching history survey courses on their respective campuses. Jim Brown of Samford University has been developing interactive three-dimensional topography models as a basis for his sophomore modem world history course. Doug Sullivan-Gonzalez, Latin American historian at the University of Mississippi, has been fine-tuning his introductory regional history courses in the Croft International Program there. We have both gravitated towards use of a "great roads" approach. Twenty years of discussion between us, including recent visits to each other's campuses and incorporation of some of the other's approaches, led up to this joint field trip. In this article we first outline an innovative "great roads" way of teaching "World History Since 1500" as it has evolved at Samford in recent years. Then at more length we develop the "Veracruz to Mexico City corridor" case study approach to the modem history of Latin America as we both now use it in our survey courses.

Studying old maps showing the transformation of Mexico City can unveil possible footprints of historic facilities and utilities that have disappeared in the process of urban modernization. The objective of this exercise is to uncover the location of old structures of Pre-Hispanic and Colonial Mexico City as a basis for creating a new footprint of urban memory and identity. A city of promenades proposes the remembrance and use of public space, such as the recuperation of lost cultural and geographic landscapes. It takes the routes and paths, the aqueducts, the roads, the moats, the ramparts, the gates of the historic city and its connections to other villages, which now conform this great metropolitan area and it revives them in order to bring communities together. Inhabitants experience a sense of belonging to a meaningful place, while looking back to the past of a growing city. These paths will serve as initiators of projects and actions which will improve patterns of use and sense of identity, offering landmarks, establishing linear parks as connectors of different scales of existing parks and, through modern design, creating a rediscovered footprint of monuments, landscapes and infrastructures long gone. This proposal is an integral project for the Mexico City Metropolitan Area. It begins at the neighbourhood level and forms part of an urban park system; connecting the surrounding natural landscapes and woodlands, the urban parks, sports clubs, neighbourhood parks, squares, bridges, central reservations, sidewalks, tree and flower beds, chapels, rights of way, unused railways, roads, avenues, greenhouses, agricultural trails, cemeteries, brooks and waterways, ravines, canals, terraces, balconies, cloisters and convent patios, archeological sites and unbuilt urban block cores. The city of paths and strolls, of boulevards, of old roads to haciendas and convents, of dikes, gateways, old custom house gates, water fountains and springs, canals, causeways, watermills and aqueducts is an academic exercise with students and teachers to find a meaningful representation of the layers of history that builds a city and creates identity.

Testo completoAbstract (sommario):
The analysis of satellite images shows an important reduction of forest cover in the Lagoon of Términos region in the State of Campeche (southeastern Mexico) over the last decades. Deforestation rates reached 2.2 and 5.3%, respectively, on a yearly basis during 19741986 and 19861991. The deforestation process was modelled using a geographic information system. The model allows to determine how elements such as roads or human settlements proximity, land tenure, shape of the forest patches, slope, soil type, and human population attributes have an impact on the deforestation process. Deforestation was more severe in opened, nonflooded areas, with fertile soil, near roads and human settlements. Human population attributes showed little influence on deforestation rates, probably because pasture lands encroachment was recognized as the main cause of forest clearing. However, the model does not highlight the root causes of this phenomena, such as government policy on settlement and subsidies for cattle ranching. Despite this limitation, it allows to generate deforestation risk assessment maps that correctly identify the forest areas most susceptible to deforestation.

"Trends in Lesser Prairie-Chicken Habitat Extent and Distribution on the Southern High Plains". Remote Sensing 14, n. 15 (6 agosto 2022): 3780. http://dx.doi.org/10.3390/rs14153780.
Testo completoAbstract (sommario):
The lesser prairie-chicken (Tympanuchus pallidicinctus) is a species of prairie grouse that occupies grassland ecosystems in the Southern and Central High Plains of the Great Plains. Reduced abundance and occupied ranges have led to increased conservation efforts throughout the species’ range. Habitat loss is considered the predominant cause of these declines. In the Southern High Plains of Texas and New Mexico, lesser prairie-chicken habitat corresponds to the Sand Shinnery Oak Prairie Ecoregion, which is comprised of a mixture of sand shinnery oak (Quercus havardii)-dominated grasslands, sand sagebrush (Artemisia filifolia)-dominated grasslands, and mixed grasslands. In sand shinnery oak–grassland communities, conversion to row-crop agriculture, continuous unmanaged livestock grazing, restriction of natural fire, invasive plant species (e.g., mesquite (Prosopis spp.)), extensive use of herbicides, energy development, and a variety of other factors have also negatively affected ecosystem extent and function. We integrated historical maps and remote sensing-derived information to measure trends in the extent and geographical distribution of sand shinnery oak prairies in eastern New Mexico and northwest Texas. Potential lesser prairie-chicken habitat was reduced by 56% from a potential of 43,258 km2 to 18,908 km2 in ~115 years (since pre-settlement). Our assessment indicated both mixed grasslands and sand shinnery oak-dominated grasslands were transformed from large parcels of existing vegetation communities to urban settlements, row crops, roads, and industrial land uses by the 1970s. Currently, potential habitat is highly fragmented and restricted to isolated locations in Texas and New Mexico, with an increasing dominance in mixed grasslands, especially in the southeastern portion of the lesser prairie-chicken range. Sand shinnery oak-dominated grasslands have been declining rapidly, from 69% of its potential extent in 1985, 65% in 1995, 54% in 2005, to 42% in 2015. Mixed grasslands drastically declined to 50% of its potential distribution by 1985. Since then, it has been stable until the 2005–2015 period when it declined to 45% of its potential extent. Based on the 2015 assessment, the current potential habitat for lesser prairie-chicken is estimated at 18,908 km2 (1,890,800 ha or 4.6 million acres), where 13,126 km2 corresponds to mixed grasslands and 5782 km2 corresponds to sand shinnery oak-dominated grasslands.

"Detection of urban growth in the state of Hidalgo using Landsat images". Journal of Geography and Cartography 5, n. 2 (31 ottobre 2022): 133. http://dx.doi.org/10.24294/jgc.v5i2.1764.
Testo completoAbstract (sommario):
The detection of urban expansion through digital processing of satellite images provides valuable information for understanding the dynamics of land use change and its spatial relationship with environmental factors. In order to apply or generate effective land-use planning policies, it is essential to have a historical record of the regional distribution of human settlements, an element that is practically non-existent in our country. For this reason, this text aims to determine the urban growth rate during the period 2000–2014 in the state of Hidalgo, Mexico, and to identify potential expansion zones from Landsat images. Six Landsat scenes were used for the spatial analysis of the state urban coverage and their relationship with the road influence area was evaluated. Two maps were obtained as cartographic products: one of urban coverage distribution and another of the municipalities with the greatest expansion, whose areas are located in the Valle del Mezquital region. However, Mineral de la Reforma, Tetepango, Tizayuca and Pachuca de Soto stand out for their growth rates during the study period: 183.44%, 102%, 94% and 68.5%, respectively. In total, the state urban area in-creased 72.3 km2 from 2000 to 2014 with an average growth rate of 1.8% per year. Such growth was associated with the areas of influence of important road infrastructure, such as the Libramiento Arco Norte in Hidalgo. Therefore, the Mezquital Valley and the Mexico Basin are considered as potential regions for urban expansion in the state.

Testo completoAbstract (sommario):
In densely populated urban areas, predicting the post-earthquake performance of a transport network is a particularly challenging task that requires the integration of modeled structural seismic response, damage scenarios, and resulting traffic behavior. Previous approaches assessing the vulnerability and performance of networks after earthquakes have not succeeded in capturing and estimating the interdependencies between seismic risk parameters and key traffic behavior variables. This paper presents a methodology, based on data analysis and optimization, where the dynamic traffic modeling and probabilistic seismic hazard assessment are coupled, to link and characterize key network performance variables after extreme earthquakes and establish a multivariable seismic performance measure. The methodology is used to study the transport network in the southern part of Mexico City for a set of scenarios. The seismic environment is established through uniform hazard spectra derived for firm soil. Damage to structures is estimated considering site response and using fragility functions. Dynamic traffic modeling is developed to simulate damage-induced road closures and resulting in traffic variations. Post-earthquake network performance is evaluated through data envelopment analyses, obtaining sets of seismic performance boundaries, and seismic performance maps. The methodology offers a quantitative tool with applications in the planning of urban areas that are sustainable and seismic resilient.

In the transport sector, communication technologies (WiFi, WAVE, Bluetooth, 3G, 4G, 5G, etc.) make the concept of a connected car with communication capabilities possible. In the coming decades, connected autonomous driving vehicles, without human intervention, and high security, will travel on roads and cities. In this field, another goal is the reduction of greenhouse gas emissions, which opens the possibility of new areas of transport research that consider the environment, energy, and the use of information exchange to guarantee safe mobility, comfortable and sustainability [1]. Electric mobility ensures sustainable and environmentally friendly urban development [2]. This research will analyze the impact electric vehicles have on the development of a smart city, for which SUMO was used as a vehicular traffic simulator, OMNeT++ for the communications network, and Veins as the link between the two, to achieve results attached to reality. Based on the above, this research hypothesizes that using electric vehicles in real simulated scenarios in the city of Mazatlán, in Sinaloa, Mexico, reduces pollution. To confirm the above, a series of simulations will be carried out that will allow us to analyze and compare the use of electric vehicles in real scenarios.

Testo completoAbstract (sommario):
Among the numerous natural hazards, landslides are one of the greatest, as they can cause enormous loss of life and property, and affect the natural ecosystem and their services. Landslides are disasters that cause damage to anthropic activities and innumerable loss of human life, globally. The landslide risk assessed by the integration of susceptibility and vulnerability maps has recently become a manner of studying sites prone to landslide events and managing these regions well. Developing countries, where the impact of landslides is frequent, need risk assessment tools that enable them to address these disasters, starting with their prevention, with free spatial data and appropriate models. Our study shows a heuristic risk model by integrating a susceptibility map made by AutoML and a vulnerability one that is made considering ecological vulnerability and socio-economic vulnerability. The input data used in the State of Guerrero (México) approach uses spatial data, such as remote sensing, or official Mexican databases. This aspect makes this work adaptable to other parts of the world because the cost is low, and the frequency adaptation is high. Our results show a great difference between the distribution of vulnerability and susceptibility zones in the study area, and even between the socio-economic and ecological vulnerabilities. For instance, the highest ecological vulnerability is in the mountainous zone in Guerrero, and the highest socio-economic vulnerability values are found around settlements and roads. Therefore, the final risk assessment map is an integrated index that considers susceptibility and vulnerability and would be a good first attempt to challenge landslide disasters.

Abstract In spring 1938, while Brighton Rock was still in the press, Greene went to Mexico. He had been commissioned by a publisher to write a book on the state of the Catholic Church in that country, where for several years it had been persecuted by a fiercely anti-religious government. He spent some weeks travelling in the remoter regions, often in great discomfort, and produced two of his best books. The Lawless Roads, the one he had been commissioned to write, is as much an autobiographical exploration as a survey of conditions in the country, while The Power and the Glory is one of his most popular novels, and at the same time one of the most profound. The Lawless Roads is a complex and artful text. It is very literary, drawing on Greene’s extensive reading, but the prose is vivid, conveying physical sensations with painful immediacy. A lighter note some- times appears, as when he discovers a community of Mexicans who are all called ‘Graham’ or ‘Greene’. There is a strong Catholic emphasis: the narrator makes efforts to hear Mass and sometimes attends Benediction as well; he goes to Confession when he is moving into a dangerous phase of his journey, and he recites ‘Hail Marys’ when he is scared in a storm.

Testo completoAbstract (sommario):
The Pan-American Highway rises in the far north of the Americas at Prudhoe Bay, Alaska and, except for a small gap in Panama, runs the entire length of the two American continents to terminate at Ushuaia in southernmost Argentina. Along its way it travels nearly 50,000 kilometres, from the polar landscape of the far north, through the boreal forests of Canada, the temperate plains and hot deserts of the USA and Mexico, and on further into the tropical zones of Central and South America, until it reaches the sub-polar landscape of Tierra del Fuego. The American landscape was not always like this. To travel along the Pan-American Highway some three million years ago, in the Pliocene Epoch, would have revealed a different world. It was a little warmer than our own. Far away, the Greenland ice sheet covered only a small part of that land mass. At the other end of the world, there was less ice covering the West Antarctic than we are familiar with today. Going south, from Prudhoe Bay along the Pan-American Highway of the Pliocene, there was none of the scrub tundra now seen by the ice road truckers. Forests then extended far to the north, covering vast areas of northern Canada and Alaska, and draping the coastal margins of Greenland. They stretched, too, into Siberia, a mass of forest extending thousands of kilometres from Norway to Kamchatka. There was almost no tundra in the north, except for a few patches in Greenland and on the far northern extremities of Siberia. Instead the polar sun rose across that well-nigh endless green Pliocene forest. Such a prehistoric journey south along the Pan-American Highway would take one across the grasslands of temperate America. These are truly ancient, having been long established even then. Patterns of seasonal temperature and rainfall, though, allowed forests to grow where none are present today. There were no humans to cut down the trees or hunt the animals that lived in the forests. There were no Great Lakes either, for no northern ice had grown yet, to scour out their floors and fill them with melt water.

This paper describes the GIS system developed for the Pemex’ pipeline network in the Valley of Mexico. The pipeline UTM coordinates, which are the basis of the GIS, were obtained from the high accuracy Geopig® inertial and caliper surveys. The survey data also included information on pipeline features and anomalies, and was incorporated into the GIS together with the metal loss data from the past in-line inspections. The system is based on the ArcView® GIS Software with the Arc View 3D Analyst™ extension that allows both the cartography and pipeline data to be viewed in 3-D space. It stores information on pipeline plan, profile, girth weld locations, dents, wall thickness, bending strains, metal loss and other features in relation to known landmarks such as roads, buildings, political boundaries and hydrology. This allows for very efficient and accurate location of pipe defects and anomalies, which is particularly beneficial where there are several pipelines running in the same right-of-way. It helps to eliminate unnecessary excavations, as well as to coordinate, plan and schedule pipeline repairs. The additional benefit of a multi-pipeline GIS system is the ability to store various information for all the pipelines in one database, which is easy to manage and update. The GIS also gives the ability to plot detailed maps, query data for effective solutions and visualize scenarios.

El Río Nuevo es una zona que se ha transformado para convertirse en una infraestructura vial, y equipamientos dispersos entre baldíos. Es resultado de decisiones hegemónicas que siguen la tendencia de un desarrollo urbano atento solamente a la modernización. Ello ha violentado rutinas locales, tradiciones y lugares que forman parte de la memoria colectiva de Mexicali, México.
Este trabajo trata los imaginarios urbanos y las prácticas sociales en los espacios públicos de dicha zona. El texto presenta evidencias empíricas apoyadas en el método etnográfico y en el análisis visual, registro que expone las tensiones generadas entre la asignación y la apropiación de la ciudad. Situados en el campo de los estudios socioculturales urbanos, se observa cómo la zona se ha convertido en un paisaje de la nostalgia confrontado con un paisaje del poder, disputa invisible en los mapas oficiales. Río Nuevo is an area that has been transformed to become a road infrastructure and urban facilities, scattered among vacant lots. It is the result of hegemonic decisions that follow the trend of urban development attentive only to modernize. This has violated local routines, traditions and places that are part of the collective memory of Mexicali, Mexico.
This article deals with urban imaginary and socio-spatial practices in the public spaces of the area. The paper presents empirical evidence supported by the ethnographic method and visual analysis, recording that exposes the tensions generated by the allocation and appropriation of the city. It located in the field of urban socio-cultural studies; we observe how the area has become a landscape of nostalgia confronted with a landscape of power, unseen dispute on official maps.

Abstract In today's ever-changing and competitive environment, oil and gas industry is quickly moving towards integrated technologies as a founding pillar of any business strategy able to meet the trilemma of the growing energy demand together with the need of an equitable supply and its environmental sustainability. Deep water drilling technologies are universally recognized among the front runner along this road map, coming from a long journey of trials and errors and capable only in the recent years to move close to the full potential made by the integration, completely machine controlled, of multiple rig equipment. This paper describes one among the first experience made in the industry of such process control automation set up on the 7th generation drilling ship Saipem Santorini in Gulf of Mexico over the years 2022 and 2023. Results achieved clearly demonstrate a tangible enhancement of the work safety, as the human/machine interface is lowered by near the 50% along the whole well construction process, as well as the drilling and completion performance went beyond the 10% of global well time reduction, just as a starting point. This first experience has been documented over a collaborative one-year period through advanced KPI monitoring and systematic approach used for installation, training, remote support and data analytics that illustrates a proven path to success which is going to be reiterated soon up to a level of a new standard for deep water drilling.

The authors of the paper represent two firms that have completed hundreds of challenging subgrade and foundation projects for the rail industry. The intent of this paper is to educate the railroad business in general about alternative approaches to common geotechnical problems facing the railroad industry. Projects have been completed across the country in nearly all geological conditions, on all of the Class I carriers, Shortlines and Mass Transit systems. Successful remediation projects associated with challenging subsurface conditions across the United States, Canada and Mexico are covered. Case histories include jet grouting for low headroom earth retention and tunnel support, stone columns for embankment support, micropiles for low headroom bridge replacement, micropiles and soil nails for earth retention, compaction, and urethane grouting for settlement of existing structures. Projects discussed include background information such as project layout, drawings and test results. Each project is completed and has a positive track record, indicating success. Projects have been specially selected to demonstrate the ability of specialty foundation solutions applicable throughout North America. Each topic provides technically sound approaches to age-old Rail road subsurface challenges. Many of these topics are not addressed in the AREMA manual; however, one of the authors, is currently addressing these topics through a proposed section of AREMA chapter 8.

Abstract In the last two decades, oil and gas operators and service companies are moving towards a more proactive rather than reactive mode in the drilling process optimization following the use of remote operating centers (ROCs) for rapid problem identification, assessment and mitigation. The methodologies adopted may be different across companies or regions but the underlying objective for most is to drill wells efficiently in a cost-effective manner. In spite of the rapid and continuous development of real time monitoring protocols, there are still gaps in the use of these aggregated data and information obtained from ROCs to achieve fully integrated drilling process modeling and optimization in real time. The paper highlights the importance of a full-integrated approach to using real time drilling engineering and optimization methodology in order to gain valuable insights that allow operational teams to execute wells with minimal non-productive Developing a functional real time drilling engineering methodology requires several years of failing fast and evolving towards a more improved performance organization where preemptive actions can be taken before problems occur. The methodology begins with performing full-integrated geomechanics study to understand the underlying geological uncertainties, stresses and faulting regimes within the area. The results from the geomechanical study form the basis for the detailed design of the casing, mud, cement, drillstring as well as the interaction of all these artifacts in order to develop operating parameters for well execution. Detailed drilling engineering road maps along with its associate risk matrices are developed to determine the operating ranges and bases of monitoring. During real time execution, these models including the 1-D geomechanical model, BHA design & modeling, casing design, fluids design, cementing design are updated continuously as more data become available in real time. The real time drilling engineering analysis coupled with integrated in-house and real-time center (iROC) personnel, 24/7 support provides immediate recommendations that can eliminate and avoid potential undesirable drilling events such as stuck pipes, lost circulations, and downhole tool failures. By applying this integrated methodology in the Gulf of Mexico, a significant improvement in technical efficiency and by extension the operational efficiencies in performance through implementing same goals(s) focus, objectives aligned with collaborative planning, integrated 24/7 real-time operations support and solutions, execution and delivering correct and detailed communication protocols with united focal points across multiple stake holders. This resulted in completed well construction phase eight days ahead of schedule, with zero safety incidents. This study validates the value of integrated services approach with focal point leadership using the right communication protocols with 24/7 monitoring and proactive support, improves the efficiency of the well construction process and ultimately lowers the cost and/or increases the production output of the project.

Abstract The Petroleum Working Group (PWG) of the United Nations Economic Commission for Europe (UNECE) has developed the Petroleum Resource Specifications and Guidelines (PRSG) to facilitate the application of the United Nations Framework Classification for Resources (UNFC) for evaluating and classifying petroleum projects. The UNFC was developed by the Expert Group on Resource Management (EGRM) and covers all resource sectors such as minerals, petroleum, renewable energy, nuclear resources, injection projects, anthropogenic resources and groundwater. It has a unique three- dimensional structure to describe environmental, social and economic viability (E-axis), technical feasibility and maturity (F-axis) and degree of confidence in the resource estimates (G-axis). The UNFC is fully aligned to holistic and sustainable resource management called for by the 2030 Agenda for Sustainable Development (2030 Agenda). UNFC can be used by governments for integrated energy planning, companies for developing business models and the investors in decision making. Internationally, all classification systems and their application continue to evolve to incorporate the latest technical understanding and usage and societal, government and regulatory expectations. The PRSG incorporates key elements from current global petroleum classification systems. Furthermore, it provides a forward-thinking approach to including aspects of integrity and ethics. It expands on the unique differentiator of the UNFC to integrate social and environmental issues in the project evaluation. Several case studies have been carried out (in China, Kuwait, Mexico, Russia, and Uganda) using UNFC. Specifically, PRSG assists in identifying critical social and environmental issues to support their resolution and development sustainably. These issues may be unique to the country, location and projects and mapped using a risk matrix. This may support the development of a road map to resolve potential impediments to project sanction. The release of the PRSG comes at a time of global economic volatility on a national and international level due to the ongoing impact and management of COVID-19, petroleum supply and demand uncertainty and competing national and international interests. Sustainable energy is not only required for industries but for all other social development. It is essential for private sector development, productive capacity building and expansion of trade. It has strong linkages to climate action, health, education, water, food security and woman empowerment. Moreover, enduring complex system considerations in balancing the energy trilemma of reliable supply, affordability, equity, and social and environmental responsibility remain. These overarching conditions make it even more essential to ensure projects are evaluated in a competent, ethical and transparent manner. While considering all the risks, it is also critical to reinforce the positive contribution a natural resource utilization project provides to society. Such an inquiry can focus on how the project contributes to the quality of life, environment, and the economy – the people, planet, and prosperity triad. Such an approach allows consistent, robust and sustainable investment decision making and energy policy development.
