AbstractThis article examines how people in Mexico's Federal District (Distrito Federal) contested transit policies and responded to the introduction of new technical infrastructures, like the electrified tram network. District officials published transit guidelines that reflected elite preoccupation with order, but their heavy-handed policies faced resistance from poor, working-class, and middle-class residents. This defiance took different forms: noncompliance, rule-breaking, public protests, and written complaints to officials and the press. Municipal governments wielded considerable power to shape policy and clashed over jurisdiction and authority over taxation and police mobility. National leaders serving the strongman president, Porfirio Díaz, undermined this influence and consolidated decision-making authority in the office of the district governor and the city council of Mexico City. They justified limiting municipal authority and democratic participation in the district as necessary to improve urban transportation infrastructure, improve tax collection, and streamline transit policy. Nevertheless, this attempt at centralization failed amid public complaints about continuing service problems and allegations of official incompetence in the Dirección de Obras Públicas (directorate of public works). After 1910, when the Mexican Revolution brought a new generation of political leadership to power, the policy was reversed, serving as an important symbolic and administrative break with the past.

En estas páginas vamos a hablar de conflictos ambientalistas en perspectiva histórica. Se presentarán dos estudios de caso en torno al servicio público o privado del agua en la Ciudad de México y al abastecimiento de la misma desde el Desierto de los Leones durante el porfiriato. Las partes en el conflicto serán: los empresarios particulares, el gobierno del Ayuntamiento de la Ciudad de México, el gobierno del Distrito Federal y el poder central. Presentaremos el conflicto como una parte del enfrentamiento entre el poder local y el poder central en un momento crítico de la historia mexicana previo a la Revolución, e introduciremos en el debate la preocupación del momento por cuestiones ambientales. Producto de este enfrentamiento fueron las primeras leyes de protección ambiental entendidas como defensa de un “proyecto nacional” en el que se considera la defensa del medio ambiente como defensa del patrimonio de la nación. AbstractThis paper discusses environmentalist conflicts in a historical perspective. Two case studies will be presented on public and private water service in Mexico City and water supplies from Desierto de los Leones during the time of Porfirio Díaz. The parties in the conflict include: private entrepreneurs, the Mexico City Town Hall government, the Federal District government and central power. The conflict is presented as part of a con­frontation between local and central power at a critical point in Mexican history prior to the Revolution and the debate will include environmental concerns of the time. This confrontation led to the first laws of environmental protection, understood as the defense of a “national Project” in which the defense of the environment is regarded as the defense of the nation’s heritage.

Dalbergia miscolobium or Jacarandá do Cerrado is a species of legume in the Fabaceae family. It occurs in the sensu stricto Cerrado and in the dystrophic cerradão. It shows potential for landscaping and for recovering damaged areas. It is an endangered species and therefore is protected by the law that prevents cut in areas of the Federal District (Decree No. 14.783/93). The purpose of this study was to determine the best procedure to prepare seeds of Dalbergia miscolobium to assess viability in the tetrazolium test. We carried out the following treatments: i) hydration on filter paper at 25 ° C, ii) hydration on filter paper at 25 ° C followed by a cut in the tegument and iii) hydration on filter paper at 25 ° C followed bya complete removal of the tegument. The results were analyzed using analysis of variance and the Tukey range test. The analyzes showed that the best procedure to prepare seeds of Dalbergia miscolobium is the treatment in which there is a hydration followed by the complete removal of the integument. Where 78% of the seeds showed uniform staining, indicating that the seeds analyzed are of good quality. The other treatments, hydration and hydration followed by cutting, showed respectively 35% and 41% of viable seeds. RESUMO A Dalbergia miscolobium ou Jacarandá do Cerrado é uma espécie de leguminosa da família Fabaceae. Ocorre no sentido stricto Cerrado e no cerradão distrófico. Possui potencial para paisagismo e para recuperar áreas degradadas. É uma espécie ameaçada de extinção e, portanto, está protegida pela lei que previne o corte em áreas do Distrito Federal (Decreto 14.783 / 93). O objetivo deste estudo foi determinar o melhor procedimento de prepararação das sementes de Dalbergia miscolobium para serem submetidas à análise de viabilidade pelo teste de tetrazólio. Foram realizados os seguintes tratamentos: i) hidratação em papel de filtro a 25 ° C, ii) hidratação em papel de filtro a 25 ° C seguida de um corte no tegumento e iii) hidratação em papel de filtro a 25 ° C seguido de remoção completa do tegumento. Os resultados foram analisados utilizando-se a análise de variância e o teste de médias de Tukey. As análises mostraram que o melhor procedimento para preparar sementes de Dalbergia miscolobium é o tratamento em que há uma hidratação seguida pela remoção completa do tegumento, onde 78% das sementes apresentaram coloração uniforme, indicando que as sementes analisadas são de boa qualidade. Os demais tratamentos, hidratação e hidratação seguida de corte, mostraram respectivamente 35% e 41% de sementes viáveis.

Unrevolutionary Mexico addresses how the Mexican Revolution (1910-1940) turned into a capitalist dictatorship of exceptional resilience. While soldiers seized power across the rest of Latin America, in modern Mexico the civilians of a single party moved punctiliously in and out of office for seventy-one years. The book uses the histories of the states of Guerrero and Veracruz as entry points to explore the origins and consolidation of this unique authoritarian state on both provincial and national levels. An empirically rich reconstruction of over sixty years of modernization and revolution (1880-1945) revises prevailing ideas of a pacified Mexico and establishes the 1940s as a decade of faltering governments and enduring violence. The book then assesses the pivotal changes of the mid-twentieth century, when a new generation of lawyers, bureaucrats and businessmen joined with surviving revolutionaries to form the Partido Revolucionario Institucional, which held uninterrupted power until 2000. Thematic chapters analyse elections, development, corruption and high and low culture in the period. The central role of military and private violence is explored in two further chapters that measure the weight of hidden coercion in keeping the party in power. In conclusion, the combination of provincial and national histories reveals Mexico as a place where soldiers prevented coups, a single party lost its own rigged elections, corruption fostered legitimacy, violence was concealed but decisive, and ambitious cultural control co-existed with a critical press and a disbelieving public. In conclusion, the book demonstrates how this strange dictatorship thrived not despite but because of its contradictions.

Proposal for improved mixes to produce concrete masonry units with commonly used aggregates available in the Valley of MexicoABSTRACTIn this paper, a proposal is done to update the masonry index compressive strength design value f*m for solid concrete masonry units for the masonry guidelines of Mexico´s Federal District Code (NTCM-2004). Solid units were made by taking into account the characteristics of the most commonly used raw materials available in the Valley of Mexico to fabricate such units in the Metropolitan Area of Mexico City. Different tests were conducted for both raw materials and the obtained concrete units. Based upon test results, it is illustrated why it is much better to design masonry structures based upon the experimental data of the units to be used at the construction site rather than using index values proposed in building codes.Keywords: masonry; concrete masonry units; compressive strength.Propuesta de mejora de mezclas para producir piezas de mampostería de concreto empleando materiales comúnmente disponibles en el Valle de MéxicoRESUMENSe presenta un estudio donde se hace una propuesta para actualizar los valores índices de la resistencia a la compresión de mamposterías (f*m) elaboradas con piezas de concreto especificados en las normas de mampostería vigentes en el Distrito Federal. Se realizó un estudio de mercado, donde se tomaron en cuenta las características de los materiales comúnmente utilizados en la actualidad en el Valle de México para la fabricación de piezas de concreto sólidas, incluyendo los resultados de distintas pruebas de laboratorio realizadas a la materia prima. Con base en estos resultados, se ilustran las ventajas de diseñar a la mampostería con base experimental en lugar de utilizar los valores indicativos que se ofrecen en las normas de mampostería.Palabras clave: mampostería; piezas de concreto; resistencia a la compresión. Proposta de melhoria de traços para produzir blocos de alvenaria de concreto utilizando materiais comumente disponíveis no Vale do México RESUMOApresenta-se um estudo onde se propõe uma atualização dos valores do índice de resistência à compressão da alvenaria (f*m) elaborados com blocos de concreto especificados nas normas de alvenaria em vigor no Distrito Federal.
