CONFIGURACIóN REGIONAL DEL TERRITORIO RELIGIOSO EN MéXICO, 1950-2000
José Luis Molina Hernández
Frontera norte , 2003,
Abstract: En este ensayo analizamos la relación entre territorio y religión desde tres perspectivas distintas: en los aspectos teórico y metodológico revisamos diferentes enfoques para el análisis de las regiones en general y para la construcción de los conceptos de territorio religioso y regiones religiosas en particular; desde un punto de vista histórico describimos algunas de las formas en que la religión resignifica al territorio a partir de su propia dinámica; y en el terreno empírico, con base en los datos de los censos nacionales de México de 1950 a 2000, reconstruimos la configuración regional del territorio religioso mexicano para cada variable religiosa en cada década. De esta forma se ilustra la distribución regional de las corrientes religiosas en México y la evolución histórica de esta distribución en la segunda mitad del siglo pasado, y con ello se sientan las bases para futuros análisis que incorporen elementos de orden más cualitativo

Abstract: a research on the fight against tuberculosis in marianao municipality was made. in cuba, this campaign since its beginning was in the hands of private entities with limited resources that were inscrupulously managed. the marianao municipality, established in 1878, had municipal administrations that implemented negative policies for the people?s interests and propitiated the spreading of tuberculosis due to the terrible working and living conditions of the population. since the triumph of the revolution, in 1959, it was established in cuba a systematic fight against tuberculosis with the introduction of the national control program that acts in a decentralized way from the municipal level. in this municipality, the incidence of tuberculosis has historically been a health problem, although at present there is a trend towards the decrease of this disease and it occupies the 13th place among the 15 municipalites of the province of havana city.
Evolución histórica del municipio Marianao: contexto en que se desarrolla la lucha antituberculosa

Revista Cubana de Medicina Tropical , 2003,
Abstract: Se realizó una investigación sobre la lucha antituberculosa en el municipio Marianao. En Cuba esta lucha desde su surgimiento estuvo a cargo de entidades privadas con recursos insuficientes e inescrupulosamente manejados. El municipio Marianao, establecido desde 1878, contó con administraciones municipales que desarrollaron una política negativa para los intereses populares, que propició la propagación de la tuberculosis por causa de las pésimas condiciones de vida y de trabajo de la población. Después del triunfo revolucionario en 1959, en Cuba se estableció la lucha antituberculosa de forma sistemática con el Programa Nacional de Control, que actúa de forma descentralizada desde el nivel municipal. En el municipio Marianao la incidencia de tuberculosis históricamente ha constituido un problema de salud, aunque la tendencia actual ha sido la disminución y ocupa el lugar 13 de entre los 15 municipios de la provincia Ciudad de La Habana.

Modificación de bentonita con Al-Fe a partir de suspensiones concentradas de arcilla Modifying bentonite with Al-fe from concentrated clay suspensions
Moreno Sonia,Molina Rafael,Hernández Yesid
Ingeniería e Investigación , 2005,
Abstract: Se reporta la modificación de una betonita colombiana con la especie mixta de Al-Fe partiendo de suspensiones de arcilla al 10 y 50% p/p, así como del material en seco, empleando como fase dispersante agua o acetona. Los sólidos obtenidos se caracterizaron con los técnicas de absorción atómica, capacidad de intercambio catiónico residual y difracción de rayos X. Se evaluó la actividad catalítica frente a la reacción de oxidación de fenol con peróxido de hidrógeno en medio acuoso diluido. Los resultados indican que los sólidos preparados en suspensión concentrada presentan propiedades estructurales, texturales y catalíticas comparables con los sólidos modificados en suspensión diluida (2% p/p). This article reports modifying a Colombian bentonite with an Al-Fe mixture from 10% and 50% p/p clay suspensions as well as dry materal, using water or acetone as dispersal phase. The solids thus obtained were characterised using atomic abdorption, residual cationic interchange ability and x-ray diffraction. Catalytic activity was evaluated regarding phenol oxidation reaction with hydrogen peroxide in diluted aqueous medium. The results indicated that solids prepared in concentraded suspension presented structural, textural and catalytic propierties comparable with modified solids in diluted suspension (2% weight).
Methodology for Volumetric Measuring Transport of River Sand, in a Laboratory Channel with Mobile Bottom  [PDF]
Martín Mundo-Molina, Jose Luis Pérez-Díaz, Daniel Hernández-Cruz
Engineering (ENG) , 2018, DOI: 10.4236/eng.2018.1011053
Abstract: Most public universities in Latin America and Mexico lack laboratories for measuring sediment transport or to do academic activities. The Research Center of the engineering faculty of Chiapas state university (UNACH by its acronym in Spanish) designed a portable prismatic channel for teaching and researching the sediment transportation in rivers. This paper presents the method to measure river sand transportation in a laboratory channel with a mobile bottom and presents the results of twenty-seven experiments done in the portable channel, using nine different slope inclinations and 27 flow and water speed values. The three main results are the following: 1) The construction of the channel with variable slopes, to experiment and measure sediment transportation. 2) A method developed for measuring the volume of sediment in a laboratory. 3) In a channel with a bottom slope of 0.071, a water flow of 2 l/s and a water speed of 1.77 m/s, the volume of transported sediment was 0.015 m3; in a channel with a bottom slope of 0.44, a water flow of 2 l/s and a water speed of 0.788 m/s, the volume of transported sediment was 0.006 m3; in a channel with the bottom slope of 0.024, a water flow of 2 l/s and a water speed of 0.62 m/s, the transported sediment was 0 m3.
Cost Comparison and Hydraulic Design of Four Types of Residential Rainwater Harvesting Systems for Small Rural Communities, Considering Natural or Anthropogenic Climate Change Factors  [PDF]
Martín Mundo-Molina, Eber Godinez, José Luis Pérez-Díaz, Daniel Hernández
Journal of Water Resource and Protection (JWARP) , 2018, DOI: 10.4236/jwarp.2018.1011066
Abstract: This document presents the technical description and cost comparison of four rainwater harvesting systems for homes, the method for its hydraulic design and an equation to estimate the minimum catchment area, with the goal to supply drinking water to segregated small communities in Mexico considering climate change effects, both natural and anthropogenic. The four Rainwater Harvesting Systems (RHS) introduced in this work are the following: two rigid, one system built with ferrocement and the other built with clay bricks, and two flexible: one is a commercial collector while the other is a system built with a 3/8-inch reinforcing bar mesh and covered with a linear low-density polyethylene geomembrane. The RHS consist in cylindrical containers built with diverse materials, and in the case of rigid RHSs, they can store up to 50,000 liters of water. Also, rigid RHSs have a longer useful life and are more resistant than flexible RHSs, but their cost is notably higher. Rigid RHSs compete in price with commercial rainwater harvesting system brands like Rotoplas, but commercial RHSs disadvantages are their lower durability, storage capacity, and resistance. On the other hand, flexible RHSs are less durable than rigid ones, although, in the case of the rainwater harvesting system made with a 3/8-inch reinforcing bar mesh, the system can be rebuilt and reused and the cost is much lower. The design of the collectors takes into consideration the climate variability of the study area, natural or anthropogenic.
