The article analyzes how printed materials and newspapers in the city of Puebla supported the independence of Mexico between March and September 1821. It highlights the broad support of public opinion for the Plan of Iguala, which guaranteed respect for religion and allowed the exercise of rights without affecting the clergy and the army. The importance of debates and discussions in the written press during this period is emphasized, as well as the participation of Bishop Pérez Martínez and Colonel Iturbide in shaping public opinion. The Plan of Iguala, signed in Puebla in February 1821, received strong support from the educated elites and established the independence of Mexico and a moderate and constitutional monarchy. The article also mentions the Treaties of Córdoba, which recognized Mexico as an independent empire in August 1821. [Extracted from the article]

A case study was conducted to evaluate the SO2 emission reduction in a power plant in Central Mexico, as a result of the shifting of fuel oil to natural gas. Emissions of criteria pollutants, greenhouse gases, organic and inorganic toxics were estimated based on a 2010 report of hourly fuel oil consumption at the "Francisco Pérez Ríos" power plant in Tula, Mexico. For SO2, the dispersion of these emissions was assessed with the CALPUFF dispersion model. Emissions reductions of > 99% for SO2, PM and Pb, as well as reductions >50% for organic and inorganic toxics were observed when simulating the use of natural gas. Maximum annual (993 µg/m3) and monthly average SO2 concentrations were simulated during the cold-dry period (152–1063 µg/m3), and warm-dry period (239–432 µg/m3). Dispersion model results and those from Mexico City's air quality forecasting system showed that SO2 emissions from the power plant affect the north of Mexico City in the cold-dry period. The evaluation of model estimates with 24 hr SO2 measured concentrations at Tepeji del Rio suggests that the combination of observations and dispersion models are useful in assessing the reduction of SO2 emissions due to shifting in fuels. Being SO2 a major precursor of acid rain, high transported sulfate concentrations are of concern and low pH values have been reported in the south of Mexico City, indicating that secondary SO2 products emitted in the power plant can be transported to Mexico City under specific atmospheric conditions. Implications: Although the surroundings of a power plant located north of Mexico City receives most of the direct SO2 impact from fuel oil emissions, the plume is dispersed and advected to the Mexico City metropolitan area, where its secondary products may cause acid rain. The use of cleaner fuels may assure significant SO2 reductions in the plant emissions and consequent acid rain presence in nearby populated cities and should be compulsory in critical areas to comply with annual emission limits and health standards.

This article discusses the establishment of textile manufacturing plants along the Atoyac River in the Mexican states of Puebla and Tlaxcala in the late 19th century, which used hydraulic energy in their manufacturing processes. The author comments on the political aspects of these industrial facilities, including the role of José Díaz Rubín, and examines laws and legislation passed relating to the factories. The conflict surrounding the management and use of the river water, which some considered private and others considered public, is also explored.

This article discusses the provision of the Cabildo Catedral de Puebla (Puebla Cathedral Chapter) in Puebla, Mexico, during the 1830s. The author analyzes the role of the bishop Francisco Pablo Vázquez in the appointment of the members of the Cathedral Chapter. He also considers the relationship between the Catholic Church and the federal government in Mexico, especially in the years following the country's independence in 1821. A brief history of the provision of the Cathedral Chapter in Mexico beginning in the 16th century is also provided.

The article discusses the relationship between Church, State, and society in Mexico between 1824 and 1914 and the social and legal separation between the Church and State resulting from the reform laws of 1859. Topics discussed include the historiography of Mexico relating to this time, the relationship between the Republican government of Mexico and the societal role of the Catholic Church, and the process of secularization in Mexican society after the passage of these laws which altered the relationship between Church and State.
