  1. Estudio del CH interestelar

    NASA Astrophysics Data System (ADS)

    Olano, C.; Lemarchand, G.; Sanz, A. J.; Bava, J. A.

    El objetivo principal de este proyecto consiste en el estudio de la distribución y abundancia del CH en nubes interestelares a través de la observación de las líneas hiperfinas del CH en 3,3 GHz. El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

  3. Estudio del sistema simbiótico AR Pavonis

    NASA Astrophysics Data System (ADS)

    Quiroga, C.; Brandi, E.; Ferrer, O.; García, L.; Barbá, R.

    Se presenta un estudio espectroscópico y polarimétrico de la binaria eclipsante AR Pavonis a partir de observaciones obtenidas con el telescopio de 2.15 m. del CASLEO (San Juan). El estudio de la naturaleza del sistema se realizó a través del análisis de algunos espectros reunidos entre los años 1990 y 1995 y de datos polarimétricos correspondientes al intervalo 1995 y 1997. El análisis espectroscópico indica que AR Pav está compuesta por una gigante roja M3.7 y una componente caliente compacta, con una temperatura mayor a 90000 K y una luminosidad del orden de 500Lsolar. A lo largo del período orbital, las variaciones observadas en flujo y en velocidades radiales, reflejan que las emisiones permitidas se forman en una región que rodea la componente caliente. El estudio de la polarización lineal de AR Pav indica que además de una componente interestelar, existe una componente intrínseca del sistema que varía temporalmente y con la longitud de onda de la luz polarizada. El distinto comportamiento del grado de polarización y del ángulo de posición observado en fases diferentes, sugiere que distintos mecanismos pueden estar actuando, dependiendo de la región de scattering observado a lo largo de la línea de la visual.

    Arnal, E. M.; Cappa, C.; Cichowolski, S.; Pineault, S.; St-Louis, N.

    Una de las causas que modifica la estructura y dinámica del medio interestelar es la acción que los vientos de las estrellas de gran masa ejercen sobre el mismo. En este trabajo, mediante el uso de datos interferométricos obtenidos en la banda de radio en la transición de 21-cm del Hidrógeno neutro y de imágenes de la emisión de continuo en las bandas de 408 y 1420 MHz, de imágenes HIRES del satélite IRAS en 60 y 100 micrones, y de observaciones de continuo obtenidas con radiotelescopios de disco simple en 2695, 4850 y 8350 MHz se ha realizado un estudio multifrecuencia de los efectos que los vientos estelares de HD 192281, una estrella de tipo espectral O5 Vn((f))p, han tenido sobre el medio interestelar que rodea a la misma.

    1995-08-01

    This report outlines the estimates that were made in 1992 of the potential load requirements for Boquillas del Carmen, a small Mexican village on the northern border of the state of Coahuila, Mexico near Big Bend National Park in southern Texas. The study was made to help determine the possibility that village might be electrified by solar or wind energy. Various estimates of are given of the potential load based on estimates ranging from basic use of lights, radio, television, and small household appliances to microwave ovens, refrigerators, and direct evaporative coolers. The low-energy consumption case was estimated to be at 23.0 kWh/month per residence per month, and the high-energy consumption case (with cooling) was 140.7 kWh/month per residence. On average, the typical residence is occupied by five individuals.

  7. La implantacion del enfoque constructivista en el aula de ciencia: Estudio de caso multiple

    NASA Astrophysics Data System (ADS)

    Arroyo Betancourt, Luz I.

    Esta investigacion estudia la implantacion del enfoque constructivista en tres aulas de ciencia del contexto puertorriqueno. Se auscultaron las practicas educativas que utilizan maestras consideradas constructivistas y la correspondencia de sus practicas educativas con los elementos esenciales de la didactica que proponen los teoricos de los planteamientos constructivistas. Se ausculto, ademas, a que vision del enfoque constructivista responden las expresiones de las maestras acerca de su practica educativa y como compara con su quehacer, a la luz de los elementos esenciales de las visiones constructivistas piagetiana, social y radical. Se utilizo el diseno de estudio descriptivo de caso multiple. El estudio se baso en entrevistas a profundidad, revision de documentos y observacion no participativa a la sala de clases. El contexto fueron tres escuelas publicas de la Region Educativa de San Juan, una elemental, una intermedia y una superior. Los resultados confirmaron que la transicion hacia el enfoque constructivista es un proceso que toma tiempo, dedicacion y la participacion en adiestramientos y readiestramientos acerca del nuevo enfoque. Las maestras coinciden en la mayoria de las practicas educativas que utilizan para implantar el enfoque constructivista de ensenanza y difieren en algunas debido, probablemente, a que han tenido que adaptarlas a los correspondientes niveles de ensenanza: elemental, intermedio y superior. Dos de las maestras planifican por conceptos generadores, mientras que una de ellas planifica siguiendo la guia que recibe del Departamento de Educacion. Difieren ademas, en el enfasis que confieren al inquirir cientifico. Con relacion a la correspondencia entre la vision manifestada por las maestras a la luz de las visiones piagetiana, social y radical, aparentemente, las preguntas del protocolo de entrevistas no lograron evocar la informacion con suficiente profundidad, por lo que la investigadora tuvo que inferir las visiones de las

  8. Estudio multiespectral del remanente de supernova W 28

    NASA Astrophysics Data System (ADS)

    Dubner, G.; Velázquez, P.; Castelletti, G.

    Se presentan observaciones en continuo de radio con muy alta resolución angular y sensibilidad del remanente de supernova (RSN) W28. Las observaciones fueron realizadas con el interferómetro Very Large Array (Estados Unidos), en las configuraciones C y D, en 1415 y 324 MHz. Por la gran extensión de este remanente (diámetro ~ 1o), las observaciones en 1415 MHz se realizaron en modo mosaico, combinando 48 apuntamientos diferentes en una única imagen. En ambas frecuencias los datos se procesaron con el agregado de observaciones de menor resolución angular, a fin de recuperar información en todas las frecuencias espaciales y obtener estimaciones precisas de densidad de flujo. Las imágenes resultantes muestran por primera vez la presencia de extensiones con forma de arco, cuya naturaleza se investiga. Las observaciones en radio se comparan con una imagen óptica de W28, y con la emisión en rayos X, observada con el satélite ROSAT. Este remanente muestra una clara morfología híbrida, tipo cáscara en frecuencias de radio y de centro lleno en las bandas óptica y de rayos X blandos.

    Olalla Gutiérrez, E.

    Hemos calculado las intensidades de las transiciones E1 a los miembros de las series de Rydberg con origen en los orbitales ``no enlazantes'' del dióxido de carbono, especie de conocida relevancia atmosférica. Se han computado, asimismo, los continuos de fotoionización correspondientes a los distintos canales de ionización, representándolos como densidad espectral de fuerza de oscilador frente a la energía del fotón incidente; mostramos los resultados df/dE para la fotoionización total de esta especie en el intervalo 15-60 eV. Todos los cálculos se han llevado a cabo mediante la formulación Molecular del Método de los Orbitales de Defecto Cuántico, MQDO [1,2]. La calidad de los resultados que presentamos se ha evaluado en base a la comparación con los datos, tanto experimentales como teóricos, disponibles en la bibliografía. El acuerdo encontrado es altamente satisfactorio

  11. Estudio ab initio del mecanismo de la reacción HSO + O3

    La reacción entre el radical HSO y el ozono ha sido ampliamente estudiada desde el punto de vista experimental debido a la importancia que tiene el radical HSO en la oxidación de los compuestos de azufre reductores y a que puede contribuir a la producción de H2SO4 [1-4]. Se realizaron diversos estudios teóricos sobre la cinética de la reacción entre el radical HSO y el ozono. La reacción del HSO con el ozono presenta tres canales diferentes : HSO + O3 &rightarrow &HSO2 + O2 &rightarrow &HS + 2 O2 &rightarrow &SO + OH + O2 La controversia existente entre los grupos experimentales sobre cuál de las tres vías es la predominante, se ha resuelto mediante un estudio teórico de todas ellas utilizando métodos ab initio. La estructura de todos los reactivos, productos, intermedios y estados de transición ha sido optimizada a nivel ab initio utilizando los métodos UMP2 /6-31G** y QCISD/6-31G**.

  13. Aptian Carbon Isotope Stratigraphy in Sierra del Rosario, Northeastern Mexico

    NASA Astrophysics Data System (ADS)

    Barragan-Manzo, R.; Moreno-Bedmar, J.; Nuñez, F.; Company, M.

    2013-05-01

    In most recent years Aptian carbon isotope stratigraphy has been widely studied in Europe where isotopic stages have been developed to correlate global events. Two negative excursions have been recorded in the Lower Aptian, the older is OAE 1a in the middle part, and a younger negative excursion labeled "Aparein level", which occurs in the uppermost part of the Lower Aptian. In Mexico previous works reported a carbon isotope negative excursion in the lowermost part of the La Peña Formation that was assigned to the onset of Oceanic Anoxic Event 1a (=OAE 1a). In this work we study the isotopic record of the δ13Ccarb of 32 bulk rock samples of limestone from the uppermost part of the Cupido Formation and the lower part of the La Peña Formation at the Francisco Zarco Dam Section (=FZD), Durango State, northeastern Mexico. The isotopic data are calibrated using the latest ammonite biostratigraphic biozonation of the Aptian. This age calibration allows us to make a precise correlation between the carbon isotopic record of Mexico and several European sections (e.g. Spain and France). In the studied Francisco Zarco Dam section we recognize a negative carbon isotopic excursion in the Dufrenoyia justinae ammonite Zone that corresponds to the "Aparein level", which we correlate using the ammonite zonation of others European sections (Figure 1). This correlation allows us to see how the negative excursion that characterizes the "Aparein level" is consistent with the C7 segment. Thus, our recent stratigraphic study allows us to conclude that the ammonite record in the lowermost part of the La Peña Formation is regionally isochronous, and correlates with the Dufrenoyia justinae Zone and Lower Aptian isotope interval C7. In agreement to these biostratigraphic data, the supposed record of the OAE 1a in the lowermost part of the La Peña Formation is not correct, and the carbon isotope negative excursion must be assigned to the younger event "Aparein level". Taking this into

    The Upper Cretaceous (late Campanian) Cerro del Pueblo Formation, Coahuila, Mexico, contains a diverse group of angiosperms represented mainly by their reproductive structures. Among these, a new permineralized infructescence is recognized based on its morphological and anatomical characters. It is a multiple infructescence composed of berry fruits with six locules, each containing a single seed with a curved embryo developed from a campylotropous ovule with pendulous placentation; integumentary anatomy is similar to that of Phytolacca spp. (Phytolaccaceae). Though this new plant from Coahuila shares reproductive characters with Phytolacca, the constant number (six) of carpels per fruit and pendulous placentation strongly support the recognition of a new taxon, Coahuilacarpon phytolaccoides Cevallos-Ferriz, Estrada-Ruiz, et Pérez-Hernández (Phytolaccaceae, Caryophyllales). This new record adds to the known plant diversity of low latitude North America (northern Mexico) and demonstrates the long geologic history of the group.

    This true-color image of Mexico was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. In areal extent, Mexico is the third largest country on the continent of North America (not counting Greenland, which is a province of Denmark), comprised of almost 2 million square kilometers (756,000 square miles) of land. Home to roughly 100 million people, Mexico is second only to the United States in population, making it the world's largest Spanish-speaking nation. To the north, Mexico shares its border with the United States-a line that runs some 3,100 kilometers (1,900 miles) east to west. About half of this border is defined by the Rio Grande River, which runs southeast to the Gulf of Mexico (partially obscured by clouds in this image) and marks the dividing line between Texas and Mexico. Toward the upper left (northwest) corner of this image is the Baja California peninsula, which provides the western land boundary for the Gulf of California. Toward the northwestern side of the Mexican mainland, you can see the Sierra Madre Occidental Mountains (brownish pixels) running southeast toward Lake Chapala and the city of Guadalajara. About 400 km (250 miles) east and slightly south of Lake Chapala is the capital, Mexico City. Extending northward from Mexico City is the Sierra Madre Oriental Mountains, the irregular line of brownish pixels that seem to frame the western edges of the bright white cumulus clouds in this image. Between these two large mountain ranges is a large, relatively dry highland region. To the south, Mexico shares borders with Guatemala and Belize, both of which are located south of Mexico's Yucatan Peninsula.

    Focus in this discussion of Mexico is on the following: geography; the people; history; political conditions; the economy; foreign relations; and relations between the US and Mexico. As of July 1987, the population of Mexico numbered 81.9 million with an estimated annual growth rate of 2.09%. 60% of the population is Indian-Spanish (mestizo), 30% American Indian, 9% white, and 1% other. Mexico is the most populous Spanish-speaking country in the world and the 2nd most populous country in Latin America. Education is decentralized and expanded. Mexico's topography ranges from low desert plains and jungle-like coastal strips to high plateaus and rugged mountains. Hernan Cortes conquered Mexico in 1919-21 and founded a Spanish colony that lasted for almost 300 years. Independence from Spain was proclaimed by Father Miguel Hidalgo on September 16, 1810; the republic was established on December 6, 1822. Mexico's constitution of 1917 provides for a federal republic with a separation of powers into independent executive, legislative, and judicial branches of government. Significant political themes of the administration of President Miguel de la Madrid Hurtado, who began his 6-year term in 1982, have been restructuring the economy, liberalizing trade practices, decentralizing government services, and eliminating corruption among public servants. In 1987, estimates put the real growth of the Mexican economy at 1.5%; the gross domestic product (GDP) had shrunk by 3.5% in 1986. Yet, on the positive side, Mexico's international reserves increased to record levels in 1987 (to about $15 billion), and its current account surplus reached more than $3 billion. Mexico has made considerable progress in moving to restructure its economy. It has substantially reduced impediments to international trade and has moved to reduce the number of parastatal firms. 1987 was the 2nd consecutive year in which Mexico recorded triple-digit inflation; inflation reached 158.8%.

    Updated age assignments and new collections of molluscan fossils from lower Cenomanian through upper Campanian strata in Texas permit a much refined biostratigraphic correlation with the rocks of New Mexico and the Western Interior. Generic names of many Late Cretaceous ammonites and inoceramid bivalves from Texas are updated to permit this correlation. Strata correlated in the west-to-east transect include the lower Cenomanian Beartooth Quartzite and Sarten Sandstone of southwest New Mexico, and the Eagle Mountains Formation, Del Rio Clay, Buda Limestone, and. basal beds of the Chispa Summit, Ojinaga, and Boquillas Formations of the Texas-Mexico border area. Middle Cenomanian strata are lacking in southwestern New Mexico but are present in the lower parts of the Chispa Summit and Boquillas Formations in southwest Texas. Upper Cenomanian and lower Turonian rocks are present at many localities in New Mexico and Texas in the Mancos Shale and Chispa Summit, Ojinaga, and Boquillas Formations. Middle Turonian and younger rocks seem to be entirely nonmarine in southwestern New Mexico, but they are marine in the Rio Grande area in the Chispa. Summit, Ojinaga, and Boquillas Formations. The upper part of the Chispa Summit and Boquillas contain late Turonian fossils. Rocks of Coniacian and Santonian age are present high in the Chispa Summit, Ojinaga, and Boquillas Formations, and in the lower part of the Austin. The San Carlos, Aguja, Pen, and Austin Formations contain fossils of Campanian age. Fossils representing at least 38 Upper Cretaceous ammonite zones are present along the transect. Collections made in recent years in southwestern New Mexico and at Sierra de Cristo Rey just west of downtown El Paso, Texas, have been well treated and do not need revision. Taxonomic names and zonations published in the pre-1970 literature on the Rio Grande area of Texas have been updated. New fossil collections from the Big Bend National Park, Texas, allow for a much refined correlation

    Past air quality modeling exercises have suggested the existence of basin drainage flows which may transport Mexico City Metropolitan Area's air pollution plume outside the Valley of Mexico Basin. The MCMA-2006 field campaign offered the opportunity to study the basin ventilation through a geographical gap in the southeast mountains of the basin. A mobile monitoring lab was placed at the Tenango del Aire town, a unique site located in this gap for measuring the pass of air masses from (and towards) the MCMA to (and from) the Cuautla Valley. O3, CO, NOx, NOy, CH2O global and UV radiation and MLH were measured continuously during MILAGRO from March 2 until April 6, together with other chemical species. Complementary backward and forward trajectories were constructed for the site using MCCM in prognostic mode during MILAGRO. An exploratory analysis of the air pollution roses measured at Tenango showed a sharp dominance of two flow patterns: one from the north well associated with relatively higher levels of primary pollutants and ozone levels; and another one from the south typically associated with lower levels primary pollutants but not so low of secondary ones as ozone. On the other hand, measured CO data at Tenango were compared with CO data measured at one local monitoring station in the town of Ocuituco in the State of Morelos. Ocuituco is located to the south of Tenango towards the Cuautla Valley. The preliminary results suggest that the back and forth pass of air masses through the Tenango del Aire - Amecameca area can be an important process in the regional transport of air pollution between two valleys and their metropolitan areas within the Central Mexico region.

  1. Heat flow and thermal processes in the Jornada delMuerto, New Mexico

    NASA Technical Reports Server (NTRS)

    Reiter, M.

    1985-01-01

    Most heat flow data in rifts are uncertain largely because of hydrologic disturbances in regions of extensive fracturing. Estimates of heat flow in deep petroleum tests within a large basin of the Rio Grande rift, which has suffered little syn-rift fracturing, may begin to provide clearer insight into the relationships between high heat flow and crustal thinning processes. The Jornada del Muerto is a large basin located in the Rio Grande rift of south central New Mexico. The region of interest within the Jornada del Muerto is centered about 30 km east of the town of Truth or Consequences, and is approximately 60 km north-south by 30 km east-west. High heat flows are estimated for the region. Values increase from about 90 mWm(-2) in the northern part of the study area to about 125 mWm(-2) in the southern part. These high heat flows are rather enigmatic because in the immediate vicinities of the sites there is little evidence of Cenozoic volcanism or syn-rift extensional tectonics. It is suggested that the geothermal anomaly in the southern Jornada del Muerto (approx. 125 to approx. 95 mWm(-2) results from some type of mass movement-heat transfer mechanism operating in the crust just below the elastic layer. This conclusion is consistent with the geologic and geophysical data which describe a thin crust, apparently devoid of features indicative of extensional-tectonics in the upper part of the lastic crust.

    The background notes on Mexico provide text and recent statistical information on the geography, population, government, economy, and foreign relations, specifically the North American Free Trade Agreement with US. The 1992 population is estimated at 89 million of which 60% are mestizo (Indian-Spanish), 30% are American Indian, 9% are Caucasian, and 1% are other. 90% are Roman Catholic. There are 8 years of compulsory education. Infant mortality is 30/1000 live births. Life expectancy for males is 68 years and 76 years for females. The labor force is comprised of 30% in services, 24% in agriculture and fishing, 19% in manufacturing, 13% in commerce, 7% in construction, 4% in transportation and communication, and .4% in mining. There are 31 states and a federal district. Gross domestic product (GDP) per capita was $3200 in 1991. Military expenditures were .5% of GDP in 1991. The average inflation rate is 19%. Mexico City with 20 million is the largest urban center in the world. In recent years, the economy has been restructured with market oriented reforms; the result has been a growth of GDP of 3.6% in 1991 from 2% in 1987. Dependence on oil exports has decreased. There has been privatization and deregulation of state-owned companies. Subsidies to inefficient companies have been stopped. Tariff rates were reduced. The financial debt has been reduced and turned into a surplus of .8% in 1992. Mexico's foreign debt has been reduced from its high in 1987 of $107 billion. Agricultural reforms have been ongoing for 50 years. Land was redistributed, but standards of living and productivity have improved only slightly. Rural land tenure regulations have been changed, and other economic reforms are expected. Mexico engages in ad hoc international groups and is selective about membership in international organizations.

    RESUMEN En este artículo se discute el papel de la familia y el vecindario en la salud de los ancianos méjico-americanos del estudio EPESE (Established Populations for Epidemiologic Studies of the Elderly) hispano. La paradoja epidemiológica consiste en que, a pesar de estar en desventaja socioeconómica, los ancianos hispanos tienen mortalidad relativamente menor que los ancianos de raza blanca. Esto es especialmente cierto cuando el anciano vive en los vecindarios donde hay un porcentaje alto de méjico-americanos. La familia también juega un papel importante en estos ancianos al disminuir el riesgo de institucionalización o de morbilidad. Asimismo, el estrés originado en problemas económicos o al depender económicamente de la familia, habiendo inmigrado en edades tardías, puede sobrepasar la capacidad de amortiguamiento del estrés y afectar la salud del anciano méjico-americano.

    A Bison. (probable Bison antiguus) distal humerus fragment was found within a Pleistocene colluvial deposit on a hillslope above Canada del Buey near White Rock, New Mexico. The Bison fossil is preserved within a buried soil with an inferred age of ca. 50-100 ka, based on soil properties and on stratigraphic position below a deposit of ca. 50-60 ka EI Cajete pumice. This represents the second oldest dated Bison in New Mexico, and one of the few occurrences of this genus in the northern mountains of the state. It is also only the second record of a Pleistocene vertebrate from Los Alamos County, and is a rare occurrence of a pre-25 ka Bison fossil in good stratigraphic context. Hillslopes in the study area are underlain by a sequence of truncated Pleistocene and Holocene soils that are inferred to represent colluvial deposition and soil formation followed by erosion in the mid Pleistocene (buried soil 'b3'), the late Pleistocene (buried soil 'b2'), and the mid-to-late Holocene (buried soil 'b1'). The surface soil is developed in depOSits that overlie 600-800 year-old Ancestral Puebloan sites. Colluvium is dominated by relatively fine-grained (fine to very fine sand) slopewash colluvium deposited by overland flow, but also includes rocky colluvium on hillslopes below mesas. The fine-grained colluvium is likely derived mainly from reworking of eolian deposits. Episodic colluvial deposition appears to, at least in part, accompany and follow episodic eolian events, with intervening periods dominated by erosion and the development of truncated soils.

    tribocorrosion processes. The formation of a coating layer on magnesium alloys from phosphonate imidazolium ionic liquids by immersion and by chronoamperometry has been described. The new coatings reduce the abrasive wear in the magnesium-aluminium alloy but they are not effective in the magnesium-zinc alloy, which prevent the formation of continuous coatings. Los liquidos ionicos son sales liquidas a temperatura ambiente o bajas temperaturas que presentan excelentes propiedades fisico-quimicas. En el presente trabajo se estudian como lubricantes en problemas tribologicos complejos como la lubricacion de metales contra si mismos, el desarrollo de lubricantes base agua y de nuevas superficies autolubricadas. Cuando no es posible reducir la friccion y desgaste mediante lubricacion, como en las aleaciones de magnesio, los liquidos ionicos se han estudiado como precursores de recubrimientos protectores. Se han determinado las interacciones superficiales y los procesos de corrosion sobre cobre y sobre acero con diferentes liquidos ionicos proticos y aproticos para desarrollar nuevos lubricantes y aditivos. En el contacto cobre/cobre, excepto el liquido ionico protico derivado del oleato, todos los liquidos ionicos estudiados presentan mejor comportamiento tribologico que el lubricante comercial Polialfaolefina 6. En el contacto acero/zafiro, los nuevos liquidos ionicos proticos son buenos lubricantes cuando se utilizan en estado puro, y, como aditivos en agua, generan peliculas adsorbidas sobre la superficie del metal reduciendo la friccion y el desgaste tras la evaporacion del agua. Para evitar el periodo de alta friccion inicial en presencia de agua, se han generado peliculas superficiales de liquido ionico sobre el acero en condiciones estaticas. El mejor comportamiento lubricante tanto en el contacto cobre/cobre como en el contacto acero/zafiro se obtiene para el liquido ionico protico derivado del anion adipato, con dos grupos carboxilicos.

    Test drilling along the Rio Grande in the Bosque del Apache Grant in Socorro County, New Mexico has shown that the area is hydrologically complex and that the quality of the ground water varies from saline to fresh within short distances both laterally and vertically. Nearly all of the riverside land in the Grant is occupied by the migratory waterfowl refuge of the Bosque del Apache National Wildlife Refuge. Potable and near-potable water is obtained from 12 wells in this area that tap sand and gravel, and the wells are capable of yielding 1,000 gallons per minute or more. Stallion Range Center, a military installation on the White Sands Missile Range, about 15 miles east of =he waterfowl refuge, needs about 100,000 gallons per day of potable water. Potable water in large quantities is not known to be available at a location closer to the Center than the refuge area. The Fish and Wildlife Service, which operates the waterfowl refuge, gave permission to White Sands Missile Range to test drill and to develop a supply well in certain areas along the Rio Grande outside the managed lands of the refuge. The U.S. Geological Survey was then asked by White Sands Missile Range to choose locations for test drilling and to monitor drilling and testing of the wells. Between 1963 and 1967 test wells were drilled and a suitable location for a supply well as found. The well would be about 250 feet deep and would tap a body of potable water that is about 100 feet in thickness and is thought to underlie an area of at least 5 square miles. This report contains diagrammatic sections that show the lateral and vertical relation of waters of different quality along the Rio Grande in a part of the Bosque del Apache Grant. Basic data are given in tables; they include records of 7 test wells and 12 high-yield supply wells, and 52 chemical analyses of ground water from the wells.

    Background The region situated where the borders of Mexico, Texas and New Mexico meet is known as 'Paso del Norte'. The Paso del Norte Collaborative was formed to study the seroprevalence of select pathogens and associated risk behaviors among injection drug users (IDUs) in the region. Methods Respondent-driven sampling (RDS) was used: 459 IDU participants included 204 from Mexico; 155 from Texas; and 100 from New Mexico. Each of the three sites used a standardized questionnaire that was verbally administered and testing was performed for select bloodborne infections. Results Participants were mostly male (87.4%) and Hispanic/Latino (84.7%) whose median age was 38. In Mexico, Texas and New Mexico, respectively: hepatitis B virus (HBV) was seen in 88.3%, 48.6% and 59.6% of participants; hepatitis C virus (HCV) in 98.7%, 76.4% and 80.0%; human immunodeficiency virus (HIV) in 2.1%, 10.0% and 1.0%; and syphilis in 4.0%, 9.9% and 3.0%. Heroin was the drug injected most often. More IDUs in New Mexico were aware of and used needle exchange programs compared with Texas and Mexico. Conclusion There was mixed success using RDS: it was more successfully applied after establishing good working relationships with IDU populations. Study findings included similarities and distinctions between the three sites that will be used to inform prevention interventions. PMID:19014605

    This study evaluates the use of polarimetric Airborne Synthetic Aperture Radar (AIRSAR) data to assess woody shrub density in a semiarid site where the vegetation consists primarily of varied mixtures of herbaceous vegetation and shrubs. AIRSAR data and field observations of vegetation cover and growth form-composition were obtained for 59 sites in the Jornada del Muerto plain in southern New Mexico. Radar signature measures examined were C-, L- and P-band backscattering coefficients (??0) for HH, HV and W polarizations, ratios of ??0HH and ??0HV to ??0VV, and the HH-VV polarization phase difference and correlation coefficient. The most effective measure for estimation of shrub density was L-band ??0HV, which distinguished among shrub density classes with no misclassification. Sensitivity of this measure to small amounts of shrub cover was indicated by successful separation of sites with <1% shrub cover from sites with 1-5% cover. Separability of shrub density classes was generally least for C-band signature measures. A distinctive radar signature was exhibited by dense stands of Yucca elata, a semitreelike plant with uniformly thick ???10 cm diameter) fibrous stems. Yucca sites were distinguished from others by their high P-band ??0HV relative to L-band ??0HV. The results are largely explained by the greater sensitivity of lounger wavelengths to larger canopy structural elements. L-band ??0HV and other measures responsive to canopy volume scattering were more strongly related to shrub than to herbaceous plant cover because woody shrub canopies have numerous stems of the intermediate size to which L-band is most sensitive, whereas stems of this size are mostly lacking in herbaceous canopies. The uniform-diameter stems of yucca have larger dimensions to which P-band is more sensitive than L-band.This study evaluates the use of polarimetric Airborne Synthetic Aperture Radar (AIRSAR) data to assess woody shrub density in a semiarid site where the vegetation consists

    NASA Astrophysics Data System (ADS)

    Gadea Borrell, Jose Maria

    This work describes a study of the vibroacoustic behaviour of laminate flooring and is partly accomplished by means of an experimental method somewhat simpler than that normally used at the present time and partly by a hybrid FEM-FDTD numerical method that reproduces the proposed experiment. The experimental configuration records the sounds emitted by laminate floors when impacted and the numerical method allows the sound produced by the laminate floor to be determined before installation by previously reproducing its sound. The registers obtained from both methods are evaluated from the psychoacoustic perspective with the aim of determining the relevant parameters involved in their perception, and thus provide a method of distinguishing the effect of the different component materials on the sound produced by this type of floor covering. In the field of building acoustics, with which this work is involved, laminate flooring is seen as a good solution for deadening the noise of impacts. This question has now become important due to stricter building acoustic regulations (DB-HR Proteccion frente al ruido" del Codigo Tecnico de la Edificacion, CTE). Laminate floors possess the advantage that they can be installed over existing floor coverings. Their lightness, which adds little additional strain to structures, and the fact that they are easy to fit, make them an attractive solution at the present time and gives them promising prospects for the future. Of the different types available, synthetic laminate floors are now the most popular by far in almost all types of building and for this reason research is being carried out on the users' opinion of their quality and convenience. Among the factors that affect the latter quality is their acoustic behaviour as regards both the insulation of sound transmitted to neighbouring rooms and the sound reflected from the floor in the room in which it is installed. The conclusions reached in this work are related to the latter

    The paper discusses the dynamic response to valley breeze circulation in Santa Maria del Oro, a volcanic lake in Mexico. Hourly records of wind measurements were used to construct a hydrodynamical model of the level fluctuations of the lake's water as well as integrated drift currents. The calculations show that the valley breeze circulation stimulates barotropic seiches in the lake with a period of 2.6 minutes and maximal level in the southwest part up to 18 mm. The drift current form two circulating rings having an opposite directions: anticyclonical in northern part of the lake and cyclonical in the southern. At the external edge of these rings the current speed can reach 20 cm/s. The measurements have shown that most part of the year the lake is strongly stratified. The maximal vertical temperature gradients are over 1°C/m in November and August, in a layer of 17-20 m.

    The 315 m of Rosario Formation exposed at the San Antonio del Mar (SADM) section (Baja California, Mexico) contains moderately-to-well preserved benthic and planktic foraminifera, calcareous nannofossils, and molluscs. Nannofossils suggest most of the SADM section was deposited within a narrow interval of the late Campanian (CC21-CC22), whereas foraminifera and molluscs suggest a younger maximum age (younger than the Globotruncana ventricosa Zone) and allow deposition over a longer interval of time. Planktic foraminifera at SADM represent common Tethyan taxa. They are largely restricted to the lower and middle portions of the section and comprise 0-???40% of foraminiferal assemblages. Stable isotopic analyses of Rugoglobigerina rugosa yield ??18OV-PDB values from -2.27%, to -2.82%, corresponding to salinity-corrected paleotemperature estimates of 26-30??C for the Late Cretaceous eastern Pacific. These estimates are as warm as modern tropical temperatures and are similar to tropical paleotemperature estimates from ??18O analyses of exceptionally preserved Maastrichtian samples; however, they are considerably warmer than most tropical Campanian-Maastrichtian estimates. Benthic foraminifera indicate outer shelf paleodepths with a slight increase in depth or decrease in benthic oxygen levels in the upper parts of the interval studied. The change in the benthic assemblage corresponds to an ???1??? positive shift in benthic ??O18, suggesting a relationship between benthic assemblages and an inferred increase in the local intensity of upwelling.

    A new lambeosaurine hadrosaurid, Velafrons coahuilensis, is described as the first lambeosaurine from the Cerro del Pueblo Formation of Coahuila, Mexico, and the first lambeosaurine genus to be named from North America in more than 70 years. Although the holotype specimen is a juvenile individual—as evidenced by its incomplete crest development and relative size compared to other North American lambeosaurines—ontogeny independent autapomor-phies have been identified including quadrate with narrow quadratojugal notch and a postorbital with well developed, dorsally positioned squamosal process. Additionally, this taxon is unique in that the prefrontal is not dorsally deflected and anteroposteriorly expanded as in other lambeosaurine taxa of its size, but rather retains the frontal-prefrontal “clamp” present in smaller individuals of other taxa. Phylogenetic analysis places Velafrons in a polytomy with numerous other fan-crested lambeosaurines. The crest structure of Velafrons more closely resembles that of Corythosaurus and Hypacrosaurus because it possesses an anteriorly projecting nasal process over the dorsal premaxilla process. Biogeo-graphically, Velafrons is one of three distinct hadrosaurids known from approximately 73.5 Ma—two lambeosaurines and one hadrosaurine—all restricted to the southern region of the Western Interior Basin of North America.

    The evolution of Southeast Gulf of Mexico comprises three main periods: pre-orogenic, syn-orogenic and post-orogenic. During pre-orogenic time, from Lower Jurassic to Campanian, the stages are the rift of Pangaea and the thermal subsidence (or drift). In drift stage two domains interacted in the space; the carbonate platforms (Bahamas, Yucatan, Organos and others), and the deepwater basins. These fluctuations were dictated by the differential subsidence and horizontal displacements of basement blocks as well as by the eustatic movements of the ocean. The Organos platform, for example, was entirely drowned since Upper Jurassic and the sedimentation continued in deepwater environment. The collision between Great Antilles Volcanic Arc and the continental margins since Upper Cretaceous modeled the Cuban orogen. Here, the southern facies thrusted over the northern section with simultaneous strike-slip movements. The interaction suddenly ceased in Eocene. The source rock levels are considerably more frequent in the deepwater domain than in the platforms. The Lower and Upper Jurassic as well as Lower and Middle Cretaceous horizons contain very high levels of organic matter. The offshore seismic shows the transition from the thrusted belt to the foreland basin with a typical triangle zone configuration. Reservoirs are expected in the Cretaceous section covered by seals conformed by early foreland basin sediments of Upper Cretaceous-Paleocene age. Foothill structures has a great potential for hydrocarbon exploration.

  1. Stratigraphic and structural analysis of the Neogene sediments of the offshore portion of the Salina del Istmo Basin, southeastern Mexico

    NASA Astrophysics Data System (ADS)

    Gomez-Cabrera, Pedro Tomas

    2003-10-01

    Southeastern Mexico has been affected by regional and local tectonic events. Regional tectonic events are the Gulf of Mexico opening and the lateral movement of micro-plates on the Pacific margin. The local tectonic events are related to salt tectonics. Autochthonous Jurassic salt serves as the detachment level for the main compressional event in the late Miocene. Jurassic salt was allochthonously emplaced in the late Miocene, then partially displaced by a huge quantity of terrigenous sediments during the Plio-Pleistocene. This research is a study of the main geological processes that have influenced the structural and stratigraphic evolution of the Neogene sediments in the offshore portion of the Salina del Istmo basin known as the Marbella area. Owing to data availability, the project was divided into regional and local studies. The regional study is based on 2D multi-channel seismic reflection data, and the local study is based on a 3D seismic streamer survey. Structural analysis in the regional study permits the recognition of four buried fold belts (Agua Dulce, Catemaco, Marbella, and Marbella Norte) trending roughly NE. These fold belts are the result of tectonic convergence in the pacific margin during late Miocene. The Agua Dulce and Marbella Norte fold belts are separated by an enormous salt withdrawal basin called the Pescadores basin. The Pescadores basin is bounded on the north by a spectacular stepped, counter-regional structure. Beyond the Pescadores basin, a salt mini-basin area is recognized in the upper continental slope. Another important structural element is the Sal Somera canopy in the southern part of the study area. Sedimentation-rate analysis, based on isochore mapping in the local study area, indicates that from SB-2.4 to SB-2.6 Ma, deposition rate peaked with a maximum of 7.5 mm/yr. Regional and local structural restorations show that, in general, the maximum allochthonous salt mobilization was during the Plio-Pleistocene because of the

    Combined magnetic and geochemical analysis were conducted on laminated sediments from Santa Maria del Oro, a crater lake in Nayarit (Mexico), to build up a model of paleoenvironmental conditions for the late Holocene. The occurrence of a severe drought at the end of the archeological Classic period (100 - 900 AD) has been documented in sites of central Mexico (Zirahuen lake and Lerma basin), the Gulf of Mexico coast (Los Tuxtlas) and the Yucatan peninsula. The effects of this climatic event are considered to have stressed the social and political situation in the Yucatan area and other sites in Mesoamerica, and resulted in the "collapse" of the Maya civilization. Santa Maria del Oro sediments between ca. 600 - 1140 AD are characterized by repeated sequences of ocher silt laminae with high inorganic carbon content, authigenic siderite, and low concentration of SD magnetic minerals, followed upward by an increase of concentrations of fine grained SD and SP ferrimagnetic minerals in brown silt laminae. This sequence is considered to represent dissolution-precipitation cycles of magnetic minerals in low erosion, concentrated waters and anoxic water-sediment interface environments. Dissolution of magnetite occurs in reductive conditions, which are considered as warmer and dryer periods. Above the ocher silt, precipitation of fine grained magnetite occurs when conditions change to oxic environments. Ostracode C and O isotopy document a negative precipitation/evaporation balance during this time period.

    A forest fire is a natural process of combustion in a specific geographical area, its occurrence depends on meteorological variables, topography and vegetation type, the wildland fires are potential sources of large amounts of pollutants. The main air pollutants are in a wildland fires particles (PM10 and PM2.5) Carbon Monoxide (CO), nitrogen oxides (NOx), volatile organic compounds (VOC's) and a negligible amount of sulfur dioxide (SO2) (Chow 1995), Was performed a study of the environmental impact on air quality in Mexico city for a wildland fire. The fire was presented in Cumbres del Ajusco Park on April 14 for the year 2013, with a duration of 26 hours and consuming an extension 150 ha of pasture, WRF-Chem and WRF-fire model were used to conduct the study, two modeling scenarios were made, one including emissions from wildfire and other without emission-fire, comparison is made between the two modeling scenarios in order to calculate on air quality in Mexico cityPM10 concentrations have a larger impact on the air quality of Mexico city, when fire emission were included, a plume of PM10 coming from fire increase ambient concentration up to 350ug/m3 and it was obtained by modeling similar to the concentration measured by a monitoring station (320ug/m3).The current limit is 120ug/m3 24 hours average. (Mexican standard NOM-025-SSA1-1993)This system for setting emissions from fire is working properly whoever further development is required.

    The City of Las Cruces is concerned about water quality in a reach of the Rio Grande that receives outfall from the City of Las Cruces wastewater-treatment plant. Water-quality samples were collected from the Rio Grande at Picacho Bridge near Las Cruces, New Mexico; from the sampling site at the City of Las Cruces wastewater-treatment plant; and from the Rio Grande at Calle del Norte Bridge near Mesilla, New Mexico. The samples were collected on 12 days from August 6, 1996, to February 28, 1997, and were analyzed for a suite of dissolved and total constituents including trace metals. Instantaneous stream discharge was measured concurrently with collection of the Rio Grande samples. At the wastewater- treatment plant, the City of Las Cruces provided instantaneous discharge rates concurrent with sampling. Quality-control measures used in this study to ensure analytical accuracy included replicate sampling, replicate analysis of split samples, ambient blanks, equipment blanks, and analysis of standard reference water samples.

    In this study, we determined the biologic activity of dichloromethane-extracted particulate matter < 10 micro m in aerodynamic diameter (PM10) obtained from filters at three sites in the Paso del Norte airshed, which includes El Paso, Texas, USA; Juarez, Chihuahua, Mexico, and Sunland Park, New Mexico, USA. The extracts were rich in polycyclic aromatic hydrocarbons (PAHs) and had significant biologic activity, measured using two in vitro assay systems: ethoxyresorufin-(O-deethylase (EROD) induction and the aryl hydrocarbon-receptor luciferase reporter system. In most cases, both EROD (5.25 pmol/min/mg protein) and luciferase activities (994 relative light units/mg) were highest in extracts from the Advance site located in an industrial neighborhood in Juarez. These values represented 58% and 55%, respectively, of induction associated with 1 micro M ss-naphthoflavone exposures. In contrast, little activity was observed at the Northeast Clinic site in El Paso, the reference site. In most cases, luciferase and EROD activity from extracts collected from the Tillman Health Center site, situated in downtown El Paso, fell between those observed at the other two sites. Overall, a statistically significant correlation existed between PM10 and EROD and luciferase activities. Chemical analysis of extracts collected from the Advance site demonstrated that concentrations of most PAHs were higher than those reported in most other metropolitan areas in the United States. Calculations made with these data suggest a cancer risk of 5-12 cases per 100,000 people. This risk estimate, as well as comparisons with the work of other investigators, raises concern regarding the potential for adverse health effects to the residents of this airshed. Further work is needed to understand the sources, exposure, and effects of PM10 and particulate organic material in the Paso del Norte airshed.

    During the last decades a number of lacustrine records from Mesoamerica have documented climatic changes and episodes of intense human impact. These records are concentrated in the Maya region and the in high altitude basins of central and eastern Mexico, few studies have been undertaken in western Mexico. We believe that a regional perspective of the recorded changes can provide a better understanding of the climatic trends and mechanisms controlling these changes as well as of the regional extent, intensity and timing of the episodes of human impact. For this reason we started a multidisciplinary project to study the lake sediments from Santa Maria del Oro (SMO), a crater lake in western-central Mexico (750 m asl). SMO is located in a region with tropical sub-humid climate(annual pp 1,250 mm/yr, mean annual temperature 21°C), with a short summer rainy season mainly related with the onset of the North American Monsoon (NAM) and the entrance of Pacific tropical storms and/or hurricanes. This site is therefore site sensitive to variations in the intensity of the NAM circulation. Two master sequences are available from this lake. A ca. 9 m long core (ca. 2,500 yr BP, with 8 AMS 14-C dates) was recovered using a Usinger piston corer from a relatively shallow area of the lake (12 m). These sediments are laminated, mostly with alternation of brown silt and sand layers. It has been studied for: magnetic mineralogy, ostracodes, geochemistry, TIC and TOC. We are now including diatom and pollen data to improve previous paleolimnological interpretations. The second sequence, also ca. 9 m long (ca. 4,500 yr BP, with 6 14-C AMS dates), was recovered using the Limnological Research Center (LRC at the U. of Minnesota) Kullemberg gravity corer (MOLE Mexico-USA-UK collaborative project). This sequence is also laminated, mostly between brown and black silts with finely laminated carbonate layers. High resolution ITRAX XRD elemental analysis data are available for this core. The

    Six seismic reflection profiles were collected in the vicinity of the Jornada Horst between Goat Mountain and Tortugas Mountain (northeast and east of Las Cruces, New Mexico) to delineate more precisely the geometry of the horst and to determine whether large, buried channels have been incised into the top of the horst. The Jornada fault zone separates the southern Jornada del Muerto ground-water basin from the Mesilla ground-water basin in the Mesilla drainage basin. The upper part of the Jornada Horst is composed of Tertiary volcanic and volcaniclastic rocks; these rocks overlie Permian sedimentary rocks. The horst, in turn, is overlain by unconsolidated sediments of the upper Santa Fe Group. Some test holes indicate that little or no ground water flows from the Jornada del Muerto ground-water basin to the Mesilla ground-water basin over some portions of the horst. However, some ground water flows through the upper Santa Fe Group deposits above some portions of the horst. Ground-water flow immediately east of the horst near U.S. Highway 70 is deflected northward in the southern Jornada del Muerto ground-water basin presumably because of the change from higher hydraulic-conductivity values of aquifer materials in the southern basin to lower hydraulic-conductivity values of materials in the horst. Incised, buried channels, if present on the horst, could be filled with alluvial material with higher hydraulic- conductivity values than those of the material in the horst. Incised, buried channels would allow ground water to readily move from the Jornada del Muerto ground-water basin to the Mesilla ground-water basin. The gross geometry of the horst--eastern extent, constraints on the western extent, and general altitude of the top--was discerned by interpretations of the seismic profiles. The presence or absence of large channels incised into the top of the horst could not be confirmed by these interpretations. However, the seismic interpretations suggest that the

    This paper summarizes the geochemical investigations about the origin and loading history of some trace metals (Ag, Cu and Zn) and nutrients (N and P) in the coastal lagoon complex of Altata-Ensenada del Pabellón, Mexico, by using the radioactive chronometers 210Pb and 228Th and the stable isotopes of C and N. The examination of sediment cores collected at different locations in the lagoon system identified a slight enrichment in metals and nutrients in some points, which was mainly associated to organic matter accumulation. Stable C and N isotope ratios revealed wastewater inputs to the lagoon system and the 210Pb geochronology showed that anthropogenic impact started 50 years ago, with the beginning of the agriculture development and the associated urban growth of the surrounding area. Several atypical 210Pb and 228Th/232Th profiles demonstrated that biological and physical disturbances are common phenomena in these environments, that frequently mask the pollution records; and therefore, considering that the contaminated sediments at some locations in the lagoon system are frequently resuspended and re-oxygenated, the pollutants will continue to be easily remobilized in the food chain.

    We describe the new species Anolis peucephilus sp. nov. from the Pacific versant of southern Mexico. Anolis peucephilus differs from all congeners by having a combination of (1) smooth ventral scales; (2) usually a patch of three greatly enlarged supraocular scales; (3) extremely short hind legs, longest toe of adpressed hind leg reaching to a point between levels of axilla and ear opening, ratio shank length/snout-vent length 0.18-0.21; (4) circumnasal usually in contact with first supralabial; and (5) a large yellowish orange dewlap in males and a very small to small white dewlap in females. In external morphology, A. peucephilus is most similar to A. omiltemanus from which it differs by having even shorter hind legs with the longest toe of adpressed hind leg reaching to a point between levels of axilla and ear opening (versus usually to ear opening, occasionally to slightly beyond ear opening or to a point between shoulder and ear opening in A. omiltemanus), a slightly larger dewlap in females, to 64 mm2 (versus to 41 mm2 in A. omiltemanus), the circumnasal usually in contact with the first supralabial (versus those scales separated by the presence of a subnasal in A. omiltemanus), and 4-6 internasal scales in the new species (versus usually 6-7 in A. omiltemanus). Furthermore, A. peucephilus differs from A. omiltemanus in hemipenial morphology (no finger-like processus on asulcate side in A. peucephilus versus such a processus present in A. omiltemanus). Also, in a preliminary molecular genetic analysis of the mitochondrial CO1 gene fragment, A. peucephilus has a genetic distance of 11.5% from A. omiltemanus. Anolis peucephilus was collected at night while the lizards were sleeping in pine trees, 2-10 m above the ground.

    Temperature-depth well data along with electromagnetic (EM) data were collected by students of the Summer of Applied Geophysics Experience (SAGE) 2015 field season in the Espanola Basin, New Mexico. The data from this year, in addition to data acquired since 2013, were used to construct a conceptual east-west cross-section of the Espanola Basin and the adjacent highlands in order to evaluate the regional flow system. Vertical geothermal gradients from several monitoring wells were measured using a thermistor. Anomalously warm geothermal gradients were mapped in the Cerros del Rio volcanic field in the basin just east of the Rio Grande. Temperature gradients are up to 70℃/km, while the background geothermal gradients in the Rio Grande rift zone generally show 28℃-35℃/km. This anomaly extends to the Buckman well field, which supplies water to the city of Santa Fe. Overpumping of this well field has led to subsidence in the past. However, discharge temperature plots indicate that the temperature gradients of the Buckman field may be rebounding as pumping is reduced. Audiomagnetotelluric (AMT) and transient electromagnetic (TEM) data were acquired in the vicinity of three monitoring wells. TEM and AMT methods complement each other with the former having depths of investigation of less than ten to hundreds of meters and AMT having depths of investigation comparable to the wells deeper than 500m. These datasets were used collectively to image the subsurface stratigraphy and, more specifically, the hydrogeology related to shallow aquifers. The EM data collected at these wells showed a trend indicating a shallow aquifer with a shallower resistive layer of approximately 100 ohm-m at 70-100 meters depth. Beneath this resistive layer we resolved a more conductive, clay-rich layer of 10 ohm-m. These resistivity profiles compliment the electrical logs provided by Jet West, which indicate shallower sandstone interbedded with silt on top of more silt-dominant layers. Our

    Recently discovered fossil flowers from the Cretaceous Cerro del Pueblo and flowers and fruits from the Oligocene Coatzingo Formations are assigned to the Rhamnaceae. The Cretaceous flower, Coahuilanthus belindae Calvillo-Canadell and Cevallos-Ferriz, gen. et sp. nov., is actinomorphic with fused perianth parts forming a slightly campanulate to cupulate floral cup, with sepals slightly keeled and spatulate clawed petals. The Oligocene fossils include Nahinda axamilpensis Calvillo-Canadell and Cevallos-Ferriz, gen. et sp. nov. (characterized by its campanulate bisexual flower with stamens opposite, adnate to and enfolded by petals; and with the ovary ripening into a drupe), and a winged fruit assigned to Ventilago engoto Calvillo-Canadell and Cevallos-Ferriz, sp. nov. The flowers and drupe features indicate closer affinity to Zizipheae and/or Rhamneae, while the single samaroid fruit suggests the presence of Ventilagineae. However, the unique character combination in the fossil flowers precludes placing them in extant genera. Nevertheless, the history of the family is long and can be traced back to the Campanian. A detailed phylogenetic revision of the group that uses morphological characters from both extant and fossil plants is needed to better understand the significance of these records as well as other important fossils of the family.

    Background The objective of this article is to present the frequency of cancer in Mexican children who were treated in the hospitals of the Instituto Mexicano del Seguro Social in Mexico City (IMSS-MC) in the period 1996–2001. Methods The Registry of Cancer in Children, started in 1996 in the IMSS-MC, is an on-going, prospective register. The data from 1996 through 2001 were analyzed and the different types of cancer were grouped according to the International Classification for Cancer in Children (ICCC). From this analysis, the general and specific frequencies by age and by sex were obtained for the different groups of neoplasms. Also, the frequency of the stage of the disease that had been diagnosed in cases of children with solid tumors was obtained. Results A total of 1,702 new cases of children with cancer were registered, with the male/female ratio at 1.1/1. Leukemias had the highest frequency with 784 cases (46.1%) and, of these, acute lymphoblastic leukemias were the most prevalent with 614 cases (78.3%). Thereafter, in descending order of frequency, were tumors of the central nervous system (CNST) with 197 cases (11.6%), lymphomas with 194 cases (11.4%), germinal cell tumors with 110 cases (6.5%), and bone tumors with 97 cases (5.7%). The highest frequency of cancer was found in the group of one to four year-olds that had 627 cases (36.8%). In all the age groups, leukemias were the most frequent. In the present work, the frequency of Hodgkin's disease (~4%) was found to be lower than that (~10%) in previous studies and the frequency of tumors of the sympathetic nervous system was low (2.3%). Of those cases of solid tumors for which the stage of the disease had been determined, 66.9% were diagnosed as being Stage III or IV. Conclusions The principal cancers in the children treated in the IMSS-MC were leukemias, CNST, and lymphomas, consistent with those reported by developed countries. A 2.5-fold reduction in the frequency of Hodgkin's disease was found

    Se presentan y discuten resultados obtenidos en el CASLEO y en el Observatorio de Las Campanas de dos cúmulos abiertos compactos con apariencia globular: Westerlund1 (BH197), ubicado en dirección hacia el centro galáctico, y Westerlund2. A partir de espectroscopía CCD integrada de ambos e imágenes CCD en las bandas VI obtenidas para el primero de ellos, se derivan sus parámetros fundamentales y se examinan sus apariencias estructurales. Se encuentra que Westerlund1 es un cúmulo joven (7 ± 3 millones de años), ubicado sobre el plano galáctico a 1.0 ± 0.4 kpc del sol, en una región caracterizada por una absorción excepcionalmente elevada (Av~=13.0 mag), en tanto que Westerlund2 es también un cúmulo joven (4-6 millones de años) ubicado sobre el plano, en una región afectada por una absorción menor (Av~=5.7 mag). Desde el punto de vista estructural, Westerlund 1 se presenta como uno de los pocos cúmulos abiertos jóvenes de la Galaxia con apariencia tipicamente globular, en contraste con los cúmulos azules de las Nubes de Magallanes en los cuales la apariencia globular constituye un fenómeno común. Westerlund2, aunque menos rico en estrellas, puede también ser incluído dentro de esta interesante clase de objetos.

    Introducción: estudios recientes sugieren que los niveles bajos de acidos grasos poliinsaturados omega-3 se relacionan con una mayor prevalencia de depresion; sin embargo, los resultados no son concluyentes. Objetivo: evaluar la asociacion entre el bajo consumo de acidos grasos omega-3 y la presencia de sintomas depresivos en jovenes universitarios del noroeste de Mexico. Métodos: se realizo un estudio transversal en una muestra de 706 universitarios de 18 a 24 anos de edad de ambos sexos. La presencia de sintomatologia depresiva se estimo con la escala de Depresion del Centro de Estudios Epidemiologicos (CES-D) empleando un punto de corte ≥ 24. El consumo semanal de acidos grasos alfalinolenico (ALA) y de eicosapentaenoico (EPA) mas docosahexaenoico (DHA) en mg/g de alimento se estimo por medio de un cuestionario de frecuencia de consumo de alimentos validado para la poblacion mexicana. La asociacion del consumo de omega-3 con la presencia de sintomas depresivos se evaluo con modelos de regresion logistica. Resultados: el 67% de los participantes fueron mujeres; en general, el 16,6% presentaron sintomatologia depresiva. El consumo bajo de ALA y EPA + DHA no se asocio con mayor prevalencia de sintomatologia depresiva antes y despues de ajustar por confusores. En aquellos casos con sintomatologia depresiva, los niveles ALA derivados solo de las nueces fueron significativamente menores. Conclusiones: en esta poblacion no se observo asociacion entre el bajo consumo de acidos grasos omega-3 y la sintomatologia depresiva. La posible asociacion entre el consumo de nueces y la sintomatologia depresiva requiere de mas estudios.

    Santa Maria del Oro Lake ( SMO) (21.37° N, 104.57° W; 750 m a.s.l.) is a quaternary crater-lake located at western Mexico in the natural border between two geological provinces: the plio-quaternary Trans-Mexican Volcanic Belt and the oligo-miocenic silicic volcanic province Sierra Madre Occidental. SMO, a tropical freshwater lake, is a warm-monomictic lake having a diameter of ca. 2 km and a mean depth at the depocenter of ca. 60 m, where three benthos cores were recovered. Contents of POP' s, total inorganic carbon (TIC), total organic carbon (TOC) and heavy metals were analyzed. Geochemistry and mineralogy also were studied in shallow sediments which corresponded to the decade of 50-60's, otherwise the beginning of industrial development of central Mexico; which is considered the possible source of emission of POP' s and heavy metals. Dioxin, furan, plaguicides and PCB' s contents were analyzed by a GC-MS applying USEPA methods. In the first 40 cm (n= 20) of the sedimentary column ( SC) the absence of POP' s was evidenced, applying a method detection limit ( MDL) of 5 μ g/ml for dioxin, furan and PCB' s. For plaguicides like chlordane and toxaphene the MDL was 0.5 μ g/ml and for plaguicides like DDT, aldrin, endrin, dieldrin, heptachlore and mirex the MDL was 5 μ g/ml. The MDL for HCB was 1 μ g/ml. The average (n= 30) for TIC, TOC and total carbon (TC) for the first 40 cm of the SC is as follows: TIC 2.4 %, TOC 3.7 % and TC 6.12 %. The average (n= 20) content (in ppm) of heavy metals for the first 20 cm of the SC is as follows: As 5.97, Cr 27.54, Cu 16.31, Ni 12.29, Pb 21.35 and Zn 82.46. These contents are roughly similar to the clarke of these metals in volcanic rocks. After the criteria of severe effect level ( SEL) of heavy metal in sediments, the content of these metals is below SEL levels. These results permit us to conclude that the sediments of SMO can be considered in unaffected state with respect to antropogenic contamination like POP' s and heavy

    A collaborative program among agencies and professionals in Mexico and the US is designing, developing and delivering specialized workshops for Mexican officials responsible for air quality management. The initial project is development and pilot delivery (Spring 1999) of a workshop for senior officials of SEMARNAP plus selected state and municipal officials. This paper describes the process for design of professional development programs in air quality management for Mexican officials. Key issues include optimum learning styles and delivery techniques; available time of senior managers for education; need for new materials versus adaptation of existing air quality management information; and utilization of the Internet and asynchronous methods to supplement the traditional workshop format. The paper describes the results of this analysis and design features and content of the initial workshop.

    The first case of allogeneic bone marrow transplantation in acute myelogenous leukemia (AML) done in Mexico is reported. The patient was a 26 year old Mexican woman who in October 1987 was diagnosed of having AML of the M2 subtype. After three cycles of the TADOP regimen (6-thioguanine, cytosine-arabinoside, doxorubicin, vincristine & prednisone), the patient entered complete remission. Unfortunately, after a seven month period of remission she suffered a relapse which was refractory to a new chemotherapy cycle. On 9/14/88 an allogeneic BMT from her HLA identical brother was performed. The conditioning regimen consisted of busulfan and cyclophosphamide. Prophylaxis for GVHD consisted of cyclosporine and methylprednisolone. The posttransplantation course was satisfactory, reaching > 500 neutrophils x 10(9)/L on day 14 and > 50,000 platelets x 10(9)/L without support on day 23 posttransplant. The patient developed fever of unknown etiology, which was satisfactorily resolved with ceftazidime, vancomycin and metronidazole. She also presented a grade II oral and esophageal mucositis. As a late complication, on day 90 posttransplant, she developed a bilateral pneumonia which was resolved with sulfamethoxazole-trimethoprim administration. Up to the time of this report (40 months posttransplant) the patient is completely asymptomatic, is under no immunosuppression, and shows no evidence of graft versus host disease or recurrent leukemia.

    Macroalgal studies in Baja California Sur have dealt mainly with occurrence and seasonality, but some areas are poorly known even for these basic data. Bahia del Rincón-La Rivera is an important high-productivity fisheries area where coastal infrastructure development is under way. A spatial characterization of the marine flora from Bahia del Rincón-La Rivera was done by intensive sampling at different depths and localities with skin and SCUBA diving. At least 500 m2 were surveyed in each site. Additionally. quantitative sampling was done in ten random 25 cm2 quadrates per site. In the intertidal section, density and cover estimates were used. We also investigated the historical records and geographical affinities. A total of 72 species were identified (most were red algae: 62%). We found no general trend in the biogeographical affinities, which varied with each taxonomic group. Most brown algae species were tropical-endemic; red algae temperate-cosmopolite and green algae tropical-cosmopolite. In the spatial assemblage structure we found a high similarity between the intertidal areas, but a low similarity in shallow or deeper areas (3-5 m). This pattern was the same when we compared the abundance of the main species. We suggest that there are significant spatial differences in recruitment and development of the assemblages in relation to vertical distribution (depth) and position along the shore. There is a clear-cut Gelidium-Jania belt in the intertidal zone and a Padina-Dictyota belt below the low tide. Sporadic and year-round species occur in the intertidal zone, annual and perennial species below the low tide line. Sites differ in recruitment and this affects the abundance of other species (such as coraline and Caulerpa species). Temperature and sedimentation affect seasonality, but community structure is relatively constant throughout the year.

    The lower to lower-upper Aptian succession of northern Mexico documents the drowning of the shallow-water Cupido/Cupidito carbonate platform system followed by deposition of the deep-water sediments of the La Peña Formation. Using δ13C stratigraphy, geochemical and mineralogical information coupled with previous microfacies, paleontological and total organic carbon (TOC) data from a stratigraphic section, which includes such lithological change, this study identifies distinctive episodes of accelerated global environmental change, and determines the paleoenvironmental conditions conducive to the deposition of TOC-rich intervals. Within the Cupidito unit, the Oceanic Anoxic Event 1a (OAE 1a) is recorded near the base of the section and the Intra-Furcata Negative Excursion in the topmost beds of the unit. The upper part of the section, within the La Peña Formation, is correlatable with the Noire level. Organic-carbon rich intervals occur in the lower and middle part of the OAE 1a, upper part of the Cupidito unit, base of the La Peña Formation, and in the Noire level equivalent. Reducing conditions within the sediment and oxic-dysoxic at the seafloor, locally controlled, persisted both before and during OAE 1a interval in the Cupidito lagoon. Oxygen-depleted conditions (dysoxic-anoxic) were more permanent and stronger during the deposition of the base of the la Peña Formation and the Noire equivalent level. It is proposed here that deposition of the lower-middle part of the OAE 1a and the base of the La Peña Formation was influenced by climate-controlled increases in detrital and accompanying nutrient influx that supplied especially biolimiting nutrients (Fe, P), fostering marine productivity and TOC burial. Upwelling of nutrient-rich deeper waters and minor arrival of nutrients from runoff, both account for the domination of radiolaria and organic-carbon burial during the Noire level equivalent.

    The concept of "Cosmography" is in disuse since the 80s of the last century, but the astronomical themes previously discussed in the school subjects of Geography and Cosmography remain in current textbooks. The use of term "Cosmography" was rescued in this research, and the study of its re-signification prompted the appearance of the term Geographic Cosmography. The Geographic Cosmography is a field of studies of the Geography, whose set of knowledge and skills is predominantly scholar. It studies the interface between terrestrial and celestial knowledge, and assigns a geographic significance to them. It examines human and natural relationships with Sidereal Space and its consequences for society and nature. O conceito de "Cosmografia" está em desuso desde os anos 80 do século XX, mas os temas astronômicos anteriormente abordados nas disciplinas escolares de Cosmografia e de Geografia permanecem nos atuais livros didáticos.

    In 1997, Mexico transformed its pay-as-you-go social security system to a fully funded system with personal retirement accounts, including management fees. This article examines changes in retirement wealth resulting from this new system. It shows that management fees have drained a significant proportion of individuals' retirement wealth and have increased the number of persons claiming a government-subsidized minimum pension, particularly from the time the system was introduced in 1997 until adjustment to management fees in 2008. Since 2008, retirement wealth accumulation has been similar to that of the previous system. En 1997, México transformó su sistema de pensiones basado en cotizaciones individuales a uno de ahorro para el retiro que incluyen cuotas por la administración de las cuentas. El presente estudio examina los cambios en el monto de las pensiones como resultado de la introducción del nuevo sistema. Los resultados muestran que las cuotas de administración han drenado una proporción significativa del ahorro para el retiro de los individuos por lo que ha aumentado el número de personas que solicita la pensión mínima garantizada subsidiada por el gobierno desde que se introdujo el sistema en 1997 hasta que se hicieron ajustes en las cuotas de administración de los fondos de pensiones en 2008. A partir de 2008, la acumulación del ahorro para el retiro ha sido similar que la del sistema anterior.

  17. Drought Studies For Mexico

    NASA Astrophysics Data System (ADS)

    Magana, V.

    2007-05-01

    Drought constitutes one of the major threats for a number of socioeconomic sectors in Mexico. Meteorological drought occurs in various temporal and spatial scales that range from a few weeks in the tropical Mexico to decades in northern Mexico. Historically, these long term droughts have had a negative impact, not only in economic activities, but in the lives of Mexicans as well. In general, short term droughts over central southern Mexico are related to El Niño conditions. However, drought may also occur when an anomalously low number of easterly waves reach the Caribbean and Mexico. El Niño and easterly wave activity may be related by the intensification of the Caribbean Low Level Jet. However, the role of this form of transient activity as a drought trigger in Mexico has not been explored in depth. The present analysis explores the possibility of more than one form of forcing to explain drought in Mexico on various spatial and temporal scales, as well as in various regions. Such approach to the study of drought may prove useful to diagnose why certain general circulation models are unable of reproducing drought patterns over Mexico.

    Addressing the effects of the 1982 crisis, through the late 1980s, on Mexico's economic and political systems and assessing the country's potential for entering a period of strong economic growth, contributors to this volume focus on oil, the primary source of Mexico's foreign exchange earnings, and on trade with the U.S., the primary means for earning foreign exchange. The authors argue that the problems Mexico faced during the crisis period are not over; indeed, the most difficult challenges lie ahead. For the remainder of the century Mexico must earn adequate revenue to service a substantial debt and to permit the economy to grow at a rate that provides opportunity for a labor force already enduring a high rate of unemployment and rising inflation. Contributors agree that the key to Mexico's economic and political stability will be control of inflation, unemployment, and large public sector deficits.

    This article reviews the literature on migration and HIV/AIDS in Mexico and Central America, including Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Most migrants travel to the US through Mexico. US-Mexico trade agreements created opportunities for increased risk of HIV transmission. The research literature focuses on Mexico. Most countries, with the exception of Belize and Costa Rica, are sending countries. Human rights of migrants are violated in transit and at destination. Migration policies determine migration processes. The Mexican-born population in the US is about 3% of US population and 8% of Mexico's population. About 22% arrived during 1992-97, and about 500,000 are naturalized US citizens. An additional 11 million have a Mexican ethnic background. Mexican migrants are usually economically active men who had jobs before leaving and were urban people who settled in California, Texas, Illinois, and Arizona. Most Mexican migrants enter illegally. Many return to Mexico. The main paths of HIV transmission are homosexual, heterosexual, and IV-drug-injecting persons. Latino migrants frequently use prostitutes, adopt new sexual practices including anal penetration among men, greater diversity of sexual partners, and use of injectable drugs.

    A cancer registry is to record the data which let us to know the epidemiology of neoplasm, but led us take a decision in medical policy about this health problem that benefit patients. In this paper we did a brief historical review about models and attempts for having a cancer registry in Mexico. However, since 1940 "the fight against cancer" was declared, we have not had a confident cancer registry today validated and built with data from whole the country. In 1982, the Registro Nacional del Cancer was created. The design and validation of a registration card in four hospitals were the main results. In 1988, the Registro Nacional del Cancer was reinforced with a computerized system for facilitation the data capture. In 1994, it was signed the first interinstitutional agreement that led to Registro Histopatol6gico de Neoplasias Malignas. In 1996, the Instituto Mexicano del Seguro Social established a cancer registry in children in Mexico with the intention to have data from this population.

    We report the results of the most recent seeing feasibility study performed in the region of Cerro Champaqui (2800m) at the mountain range of Sierras Grandes at the Province of Cordoba. We also describe the high frequency DIMM device built for this and other seeing samplings obtained at the provinces of San Juan; San Luis and Cordoba. This work is part of a long term project started in 2006; in search of sites of very low turbulence and suited for near infrared telescopes with active and adaptive optics. Two of the sites have been monitored during a total of 46 nights distributed in six months of the period 2011-2012. The preliminary results suggest the existence of `sub-arcsecond' seeing conditions during extended periods of time in at least one location in the mountain range in the SW of Cordoba and NE of San Luis provinces.

    The site effects and the source parameters, are inverted from a Fourier displacement spectra of seismograms that are corrected by geometrical spreading and regional attenuation valid for south center of Mexico(Ordaz and Singh, 1992). We used Genetic Algorithms (GA) to perform the non-linear inversion, like in the MAI method (Moya et al., 2000) . The GA have proved to produce better results than other traditional methods which are frequently trapped in a local minimum. GA is a method that mimics the evolution laws in living creatures. The best individuals reproduce and develop themselves with every generation. In our case each individual correspond to one source and the genes correspond to the source parameters. As in nature, the best source remain and are improved with each iteration. We assume that the site effect at each station are the same independently of the earthquake, because of that we can search for the combination of sources that can produce the smaller standard deviation of the estimated site effects from the different Fourier displacement earthquake spectra. Then we use the obtained site effects to generate a Fourier displacement spectra of an earthquake scenario. With this, we are able to compute the response spectra by means of random vibration theory (Reinoso et al., 1990). We apply this method to four stations located in the Acapulco City, Mexico, that recorded four earthquakes with epicenter located in the Guerrero Subduction Zone. The site effect estimated for one of the stations, called ACAZ, shows a good agreement with the estimated by Chávez-García et al. (1994) using spectral ratios between the ACAZ station and a rock reference site. Also we compare the response spectra from other earthquake, obtained by the former method and the response spectra computed using the acceleration record. We find an acceptable correlation between them. Chávez-García, J. Cuenca y M. Cárdenas (1994), "Estudio complementario de efectos de sitio en Acapulco

    Abstract This analysis of aging and income security in Mexico establishes that the older population in Mexico is increasing quickly and that this population is especially vulnerable to poverty. Mexican citizens are living longer and overall have experienced an improvement in the quality of life compared to that of prior generations. However, this study demonstrates that social improvements are not affecting the daily lives of all persons equally. The authors attempt to uncover and highlight those differences. One of the primary challenges facing Mexico is a growing older population. The demographic transition in Mexico combined with the lack of formal sources of income in retirement place many older persons in a state of financial insecurity. The information contained in this study and the proposed policy research areas are intended to enlarge the portfolio of options for older Mexicans. The authors analyze wealth and sources of income during retirement, the relationship between health and wealth, urban and rural disparities, and the impact of migration spells to the United States on wealth accumulation and health insurance in Mexico.

Les valeurs de K' les plus fréquentes dans les plaines de Chalco et de Texcoco sont entre 1E-09 et 1E-08 m/s, avec des moyennes similaires de 1.19E-09 et 1.7E-09 m/s respectivement, qui sont d'un ou deux ordres de grandeurs supérieures à la conductivité de la matrice. Dans la plaine de Mexico, la moyenne est proche d'un ordre de grandeur en moins, avec 2.6E-10 m/s. Ce contraste entre le K' mesuré et celui de la matrice est attribué à la présence de fractures dans les 25-40 m supérieurs, ce qui est en accord avec les études précédentes sur la migration de solutés au travers de l'imperméable. El acuífero principal del Área Metropolitana de la Ciudad de México está recubierto por un acuitardo regional lacustre, cuya conductividad hidráulica es fundamental para evaluar la protección natural de las aguas subterráneas contra los contaminantes presentes en superficie y su respuesta hidráulica. Este estudio analiza la distribución y variación de dicha conductividad en las llanuras de Chalco, Texcoco y Ciudad de México (tres de los seis lagos que existían al principio en la Cuenca de México) a partir de 225 ensayos de campo en piezómetros múltiples existentes, ubicados entre 2 y 85 m de profundidad. La interpretación de los ensayos se ha realizado mediante el método de Hvorslev y-algunos-el de Bouwer-Rice. Los resultados indican que la distribución de la conductividad se ajusta a modelos de regresión lognormales. Las frecuencias dominantes en las Llanuras de Chalco y Texoco están comprendidas entre 1-9 y 10-8 m/s, con medias de población similares de 1.19×10-9 y 1.70×10-9 m/s, respectivamente, que son dos órdenes de magnitud mayores que el valor de la matriz. En el Llano de México, la media es casi un orden de magnitud inferior (2.60×10-10 m/s). Se atribuye este contraste

    Los Alamos National Laboratory`s Technical Area 54 (TA-54) contains a radioactive waste storage and disposal facility. It is located on Mesita del Buey, which extends east-southeasterly on the New Mexico`s Pajarito Plateau. This mesa is one of a series of narrow mesas, hundreds of meters wide, that define the topography of the plateau. The mesas are separated by steep canyons, tens to hundreds of meters deep. Pajarito Canyon is to the south of Mesita del Buey, while Canada del Buey lies to the north. In general, the entire plateau slopes downward toward the east and the Rio Grande Valley, with the highest peaks of the Jemez Mountains to the west. Meterological observations collected at various sites around the Pajarito Plateau indicate that the atmospheric conditions in the area are complex and strongly influenced by the highly-variable local topography. For this study, numerical simulations of the atmospheric circulations in the area around TA-54 are carried out to produce a more detailed depiction of the wind flow than can be provided by the Laboratory`s network of meterological observation towers. Plumes of particles released into these wind fields are simulated as an indication of transport and diffusion from a hypothetical release. 4 refs., 1 fig.

    The outbreak of highly pathogenic avian influenza (HPAI) H5N2 in Mexico in 1994 led to a clear increase in biosecurity measures and improvement of intensive poultry production systems. The control and eradication measures implemented were based on active surveillance, disease detection, depopulation of infected farms and prevention of possible contacts (identified by epidemiological investigations), improvement of biosecurity measures, and restriction of the movement of live birds, poultry products, by-products and infected material. In addition, Mexico introduced a massive vaccination programme, which resulted in the eradication of HPAI in a relatively short time in two affected areas that had a high density of commercial poultry.

    The Mexican Federal Government through its Secretaria de Energia and the Federal Government owned electrical utilities, Comision Federal de Electricidad and Luz y Feurza del Centro, are doing very important efforts in order to give electric power to remote villages in Mexico via PV stand alone systems and hybrid systems with PV modules, wind generators, batteries and a back up diesel electric generator. Nowadays they are trying to take advantage of municipal solid waste in order to get power from the biogas generated in landfills. The main reason for this is, after NAFTA was signed, the municipal authorities in charge of final disposal of MSW will not be allowed any longer to throw away MSW in open fields. Besides, municipal authorities are also in charge of street lighting systems and they have to pay to the utilities a very high rate (12 cents/kWH). The main idea of this paper is how to dispose properly of MSW, fulfilling what is written in the new Environmental Law, and how to take advantage of this process in order to get power from landfill gas at marginal cost. A power wheeling agreement must be reached with the utility in order to send the power generated at the biogas facility to the street lighting lamps, avoiding the high rate for this purpose.

    An overview of food security and nutrition in Mexico is presented, based on the analysis of the four pillars of food security: availability, access, utilization of food, and stability of the food supply. In addition, the two faces of malnutrition in Mexico were analyzed: obesity and undernourishment. Data were gathered from the food security indicators of the United Nations's Food and Agriculture Organization, from the Mexican Scale of Food Security, and from the National Health and Nutrition Survey. Mexico presents an index of availability of 3 145 kilocalories per person per day, one of the highest indexes in the world, including both food production and imports. In contrast, Mexico is affected by a double burden of malnutrition: whereas children under five present 14% of stunt, 30% of the adult population is obese. Also, more than 18% of the population cannot afford the basic food basket (food poverty). Using perception surveys, people reports important levels of food insecurity, which concentrates in seven states of the Mexican Federation. The production structure underlying these indicators shows a very heterogeneous landscape, which translates in to a low productivity growth across the last years. Food security being a multidimensional concept, to ensure food security for the Mexican population requires a revision and redesign of public productive and social policies, placing a particular focus on strengthening the mechanisms of institutional governance.

    Although the Mexican population has traditionally been malnourished, the prevalence of obesity in children and adults has increased by almost 50 % in the last 10 years. Recent studies show substantial changes in the nutritional status of Mexicans, especially in the pediatric population. Among the factors associated with the development of obesity are overeating, sedentariness, and genetics. The apparent economic development in Mexico, as well as the influence of dietary patterns from other countries, have contributed to modifying lifestyle. Despite measures taken by the health system, iron- and zinc-deficiency anemia continue to be prevalent. The present review aims to describe the changes that have taken place in Mexico in the last few decades leading to a generation of short and obese children, as well as to determine the associated factors in order to promote healthier eating patterns among the Mexican population.

    Excess body weight (overweight and obesity) is currently recognized as one of the most important challenges of public health in the world, given its size, speed of growth and the negative effect it has on the health of the population that suffers. Overweight and obesity significantly increases the risk of chronic no communicable diseases, premature mortality and the social cost of health. An estimated 90 % of cases of type 2 diabetes mellitus attributable to overweight and obesity. Today, Mexico is second global prevalence of obesity in the adult population, which is ten times higher than that of countries like Japan and Korea. With regard to children, Mexico ranks fourth worldwide obesity prevalence, behind Greece, USA and Italy. In our country, over 70 % of the adult population, between 30 and 60 years are overweight. The prevalence of overweight is higher in men than females, while the prevalence of obesity is higher in women than men. Until 2012, 26 million Mexican adults are overweight and 22 million obese, which represents a major challenge for the health sector in terms of promoting healthy lifestyles in the population and development of public policies to reverse this scenario epidemiology. Mexico needs to plan and implement strategies and action cost effective for the prevention and control of obesity of children, adolescents and adults. Global experience shows that proper care of obesity and overweight, required to formulate and coordinate multisectoral strategies and efficient for enhancing protective factors to health, particularly to modify individual behavior, family and community.

    1994-01-01

    To determine the prevalence of firearm ownership and storage practices in New Mexico, we did a random-digit-dialing survey of New Mexico residents in October 1991. Of 200 households surveyed, 79 (40%) had 1 or more firearms in the home. Rural households were more likely than urban households to have firearms (44% versus 30%), and households with annual incomes of greater than $25,000 were more likely to have a firearm than households with incomes of $25,000 or less (41% versus 33%). Household firearm ownership did not vary with the presence of young (< 15 years old) children (38% with children versus 41% without). Handguns were generally owned for self-protection, and rifles were owned for hunting. Of households with firearms, 24% stored them unsafely (unlocked and loaded or unloaded but with ammunition nearby), including 21% of households with young children. Of the households with handguns only, 40% stored these firearms unsafely compared with 13% of those with rifles only. The prevalence of gun ownership in New Mexico is similar to that reported in national surveys; handguns are stored less safely than rifles; and the presence of young children in the home does not appear to improve firearm storage safety.

  4. Environmental lead in Mexico.

    PubMed

    1991-01-01

    From the data presented here, it can be concluded that environmental exposure to lead is a particularly severe problem in Mexico. As has been shown, there are very important sources of exposure to this metal: (a) for rural populations who manufacture and/or utilize lead-glazed pottery, (b) for urban populations who are exposed to high air lead concentrations due to the continued use of lead fuel additives, (c) for workers of several industries, mainly those of batteries and pigments, (d) for consumers who routinely eat canned foods such as hot peppers and fruit products, and (e) for the general population living in the vicinity of smelters, refineries and other industries that emit lead. Therefore, in Mexico only those native populations living in very primitive communities, far away from all civilized life, could be expected to be free from this exposure. At the same time, and despite the relatively few data available, it can be stated that the exposure to lead of populations in Mexico could be approaching levels that might be highly hazardous, in particular for the neuropsychological health of children. Regarding the presence of lead in the environment, despite the fact that the available studies are not enough, it is evident that pollution by this metal is widespread and that there is a serious lack of studies for most regions of the country, including several that might be expected to be highly polluted. At the same time, it is evident that the official attention paid to the problem, either in regulations, support of further studies, or implementation of effective control measures has been far from the level needed according to the available data. Lead in gasoline is still used at very high concentrations in all the country, with the exception of Mexico City and its surrounding area, while no studies have been carried out to determine the potential health and environmental impact of this practice in regions outside Mexico City. Despite the fact that the Torre

  8. Estudio del hidrógeno neutro alrededor del remanente de la supernova de Tycho

    NASA Astrophysics Data System (ADS)

    Reynoso, E. M.; Velázquez, P. F.; Dubner, G.

    With the aim of studying the interstellar gas around Tycho's supernova remnant (SNR), we have analyzed HI 21 cm high resolution data. The high resolution image reveals that this SNR is placed inside a hollowed structure, being the highest density region closest to the NE edge of the remnant. This neutral gas concentration would explain the Balmer emission associated with this SNR observed in the optical range (Smith et al. 1991, ApJ 375, 652). The HI density gradient observed in the surrounding of this SNR does not account for the different expansion rates observed along the shell (Reynoso et al. 1997, ApJ 491, in press). This fact would be suggestive that those variations are intrinsic to the explosion and that the influence of the ambient medium is still not important on the dynamical evolution of the schock front, as expected for young SNRs. We have detected HI structures at higher velocities, whose connection with this SNR is uncertain

  9. [The legacy of Cajal in Mexico].

    PubMed

    Díaz, J L

    Santiago Ramón y Cajal (1854-1934) had achieved a sound school of neurobiology displaying an integrative and anatomo-functional paradigm of study of the Nervous System by integrating diverse morphological, physiological, and clinical sciences during the Second Spanish Republic. Such school flourished in the three locations of the Cajal Institute in Madrid, but was nearly lost during the Spanish Civil War (1936-1939) with the repression of the majority of the collaborators of the recently-extinct master. One part of these mature and capable researchers was able to reach sanctuary in the Americas to continue their research and teaching enterprises. Thanks to the welcoming policy of Mexican president Lázaro Cárdenas several of them developed an extensive work at the National University of Mexico (UNAM) becoming pioneers, founders of research institutions, and venerable teachers of several medical and neurological sciences. Among them are neuropsychiatrist Dionisio Nieto, pathologist Isaac Costero, both pupils of Pío del Río Hortega; physiologist José Puche and pharmacologist Rafael Méndez, both collaborators of Juan Negrín. The work of Dionisio Nieto is especially worthy to remark as beneficiary of the Cajal School since, among many other achievements, he applied the techniques of Del Río Hortega to study the neuropathology of epilepsy and schizophrenia since the 1950's. Besides from his legacy to Mexican psychiatry, Nieto's pupils have extended his neuroanatomical and histological work, such as Alfonso Escobar, or his psycho physiological leads, such as Augusto Fernández-Guardiola. The latter was another Spanish War refugee who before is death in 2004 published a profound testimonial pertaining to the neurosciences of the Spanish exile in Mexico.

    We used mitochondrial DNA (mtDNA) sequence data and allele frequencies at eight microsatellite loci to examine the population genetic structure, estimate the divergence times of distinct lineages, and infer patterns associated with host colonization in populations of the bark beetle Dendroctonus approximatus in Mexico. Two haplotype groups were identified using mtDNA sequences in 71 individuals from 15 populations. The first group was distributed in the Sierra Madre Occidental (SMOc, Western Mexico), with some populations in the Faja Volcánica Transmexicana (Central Mexico), and the second was found in the Sierra Madre Oriental (SMOr, Eastern Mexico), with populations in the Sierra Madre del Sur (Southern Mexico). The estimated split between groups occurred in the late Pleistocene, around 0.195 Mya. Microsatellite allele frequencies revealed high genetic differentiation between pairwise populations, and genetic differentiation values indicated a genetic structure of isolation by distance. Both mtDNA sequence data and microsatellite allele frequencies indicated that D. approximatus had two independent colonization routes in Mexico, one through the SMOc and another along the SMOr. The widespread geographic distribution of D. approximatus in Mexico follows a model of population range expansion of two haplotype groups in which gene flow is restricted by the geographic separation between hosts imposed by physical barriers between populations.

    During March of 2006 we participated in MILAGRO (Megacities Initiative: Local and Global Research Observations), a multi-platform campaign to measure pollutants in and in outflow from the Mexico City metropolitan area. As part of MILAGRO we collected whole air canister samples at two Mexico City ground sites: the Instituto Mexicano del Petroleo, located in the city, northeast of the center, and the Universidad Technologica de Tecamac, a suburban site approximately 50 km northeast of the city center. Samples were also collected in various other locations throughout Mexico City. Over 300 whole air samples were collected and analyzed for a wide range of volatile organic compounds (VOCs) including methane, carbon monoxide, nonmethane hydrocarbons (NMHCs) and halocarbons. Propane was the most abundant NMHC at both the urban and suburban locations, with mixing ratios frequently in excess of 10 parts per billion at both locations. This is likely the result of the widespread use of liquefied petroleum gas (LPG) of which propane is the major component. For most species, median mixing ratios at the urban sites were significantly greater than at the suburban site. Here we compare results from both urban and suburban locations and also examine the influence of transport on the composition of outflow from Mexico City.

  16. Crustal structure across southern Mexico inferred from gravity data

    NASA Astrophysics Data System (ADS)

    Campos-Enríquez, J. O.; Sánchez-Zamora, O.

    2000-11-01

    We present a gravity model of the crustal structure in southern Mexico based on interpretation of a detailed marine gravity profile perpendicularly across the Middle America Trench offshore from Acapulco, and a regional gravity transect extending into continental Mexico across the Sierra Madre del Sur, the central sector of the Trans-Mexican Volcanic Belt, the Sierra Madre Oriental, the Coastal Plain, and into the Gulf of Mexico. The elastic thickness of the Cocos lithospheric plate was found to be 30 km. In agreement with a previous seismic refraction study, no major differences in crustal structure were observed on both sides of the O'Gorman Fracture Zone. The gravity high seaward of the trench is interpreted as due to the incipient flexure and crustal thinning. The gravity low at the axis of the trench is explained by the increase in water depth and the existence of low-density accreted or continental-derived sediments (2.25 and 2.40 g/cm 3). A gravity high of 50 mGal extending about 100 km landward is interpreted as caused by local shoaling of the Moho. The crust attains a thickness of 42 km under the Trans-Mexican Volcanic Belt but thins beneath the Coastal Plain and the continental slope of the Gulf of Mexico. Gravity highs around the Sierra de Tamaulipas are interpreted in terms of relief of the lower-upper crustal interface, implying a shallow basement.

    Twenty percent of Mexico's territory consists of karst terrain, which has been classified in two main provinces: one is the peninsula of Yucatan and the mountain systems of Chiapas and the other karst bodies are distributed in the Sierra Madre del Sur and Sierra Madre Oriental. These karst bodies developed in rocks of Triassic and Cretaceous age. Due to the importance of karst features in Mexico, the International Association of Hydrogeologists through the Karst Comition requested the collaboration of the Institute of Geology, UNAM, to compile a map of soluble surface rocks in Mexico. This work seeks to classify and georeference karst locations and generate a database to link these sites with karst geological formations and lithologies, as well as geomorphological processes that have contributed to the formation of the karst bodies. Also, we want to provide a basis for cave and karst research and for management of karst resources. In order to produce a national karst map in digital form, the tools being used are: the geographical information system Arc View and Google Earth, with the support of scientific journals, hiking and speleological documents, and 1:50000 scale geological maps of Mexico elaborated by the Institute of Geology, UNAM.

    Few historical streamflow and water-quality data are available to characterize the segment of the Rio Grande/Rio Bravo del Norte (hereinafter Rio Grande) extending from near Presidio to near Langtry, Texas. The U.S. Geological Survey, in cooperation with the National Park Service and the Texas Commission on Environmental Quality, collected water-quality and streamflow data from the Rio Grande from near Presidio to near Langtry, Texas, to characterize the streamflow gain and loss and selected constituent concentrations in a 336.3-mile reach of the Rio Grande from near Presidio to near Langtry, Texas. Streamflow was measured at 38 sites and water-quality samples were collected at 20 sites along the Rio Grande in February, March, and June 2006. Streamflow gains and losses over the course of the stream were measured indirectly by computing the differences in measured streamflow between sites along the stream. Water-quality data were collected and analyzed for salinity, dissolved solids, major ions, nutrients, trace elements, and stable isotopes. Selected properties and constituents were compared to available Texas Commission on Environmental Quality general use protection criteria or screening levels. Summary statistics of selected water-quality data were computed for each of the five designated subreaches. Streamflow gain and loss and water-quality constituent concentration were compared for each subreach, rather than the entire segment because of the temporal variation in sample collection caused by controlled releases upstream. Subreach A was determined to be a losing reach, and subreaches B, C, D, and E were determined to be gaining reaches. Compared to concentrations measured in upstream subreaches, downstream subreaches exhibited evidence of dilution of selected constituent concentrations. Subreaches A and B had measured total dissolved solids, chloride, and sulfate exceeding the Texas Commission on Environmental Quality general use protection criteria

    Dark brown crystals, up to 10 mm long, occur in rhyolite at Mexquitic, San Luis Potosi, Mexico. They are short prismatic, showing {1120}, {3030}, {1011}, {0221}, with c/a 0.4521, measured with a goniometer, and distinct {1120} cleavage. With an unusual combination of cell dimensions, high density, high refractive indices, and extreme birefringence, this tourmaline falls outside the known elbaite-schorl and schorl-dravite series. A chemical analysis, recalculated on the basis of cell volume and density, gives close to the theoretical 150 atoms per cell, whether the iron is ferrous or ferric, but the physical properties indicate a ferric tourmaline.

    Geologic, geochemical and geophysical indicators delineated during a study of the Gila Wilderness, New Mexico indicate that there are areas of probable and substantiated mineral-resource potential for gold, silver, tellurium, molybdenum, copper, lead, zinc, and fluorite. The areas which have resource potential lie along both sides of the western and southwestern boundaries of the wilderness, and adjacent to the access corridor to the Gila Cliff Dwellings National Monument in the eastern part of the wilderness. Areas marked by geothermal springs along Turkey Creek and Middle Fork of the Gila River have a probable potential for geothermal energy. No other energy-resource potential was identified within the study area.

    2008-12-01

    Many parts of Mexico City are undergoing rapid subsidence due to extraction of ground water in excess of natural recharge. We use PSInSAR (Persistent Scatterer InSAR) to investigate the link between surface deformation and ground water withdrawal. From 23 Envisat acquisitions, we obtain a time-series of surface deformation between January 2004 and July 2006 showing that the eastern part of Mexico City presents a high subsidence rate as high as 30 cm/year. This subsidence is clearly tied to declining ground water levels. We use TU Delft's Doris and PSI Toolbox for interferogram generation and PS processing. Assuming constant subsidence rates, we have obtained a dense, coherent deformation map throughout the area. Comparison between GPS and PSInSAR inferred rates show agreement in the longer term signal; we will also show initial results of GPS/PSInSAR comparison on shorter time scales. The high density of persistent scatterers allows us to detect differential deformation of urban infrastructure. Our analysis indicates that in some cases the rate of an individual persistent scatterer can differ about 3-4 cm/yr from local deformation. While some bigger buildings show slower subsidence, others have faster rates. It is important to note that in some large buildings we detected differential vertical motion, suggesting that these buildings are subject to shear stresses associated with local deformation.

    1995-05-01

    A preliminary wind energy resource assessment of Mexico that produced wind resource maps for both utility-scale and rural applications was undertaken as part of the Mexico-U.S. Renewable Energy Cooperation Program. This activity has provided valuable information needed to facilitate the commercialization of small wind turbines and windfarms in Mexico and to lay the groundwork for subsequent wind resource activities. A surface meteorological data set of hourly data in digital form was utilized to prepare a more detailed and accurate wind resource assessment of Mexico than otherwise would have been possible. Software was developed to perform the first ever detailed analysis of the wind characteristics data for over 150 stations in Mexico. The hourly data set was augmented with information from weather balloons (upper-air data), ship wind data from coastal areas, and summarized wind data from sources in Mexico. The various data were carefully evaluated for their usefulness in preparing the wind resource assessment. The preliminary assessment has identified many areas of good-to-excellent wind resource potential and shows that the wind resource in Mexico is considerably greater than shown in previous surveys.

    A partir del estudio de los Efectos Gravitomagnéticos en cuerpos masivos rotantes, planteamos la expresión para medir el desfase en el tiempo, para diferentes observadores, que se dan cuando viajan dos rayos de luz por una guía de onda o de manera libre (geodésicas), en el plano azimutal y en el plano polar. Con lo anterior queremos abordar el experimento tipo Michelson y Morley, de forma que podamos involucrar el valor de la densidad del momento angular (a) en el retraso temporal para los dos haces de luz que viajan por los brazos del interferómetro, cuando este último es ubicado en el plano ecuatorial.

    We relate in this article a didactic experience studying the moon phases with a group of middle school students of a private school of the municipality of Passo Fundo, RS. Based on David Ausubel's Meaningful Learning Theory, we have sought to develop a proposal following a didactic model which simulates the phases of the Moon, as based on the previous conceptions of the students. The signs of learning were evidenced by means of memory registries of the activity. From the obtained results we believe that the proposal achieved its goals, since the students were able to identify, differentiate and transfer the phenomenon of the moon phases to new contexts. Thus, it is concluded that a methodology focused on a meaningful content for the students is fundamental to the construction and genuine grasping of what is being learned. Neste artigo, relata-se uma experiência didática de estudo das fases da Lua com uma turma do 6° ano do Ensino Fundamental, de uma escola privada do município de Passo Fundo, RS. Tendo como fundamentação teórica a Teoria da Aprendizagem Significativa de David Ausubel, buscou-se desenvolver a proposta a partir de um modelo didático que simula as fases da Lua e com base nas concepções prévias dos estudantes. Os indícios da aprendizagem foram constatados através de registros de memórias da atividade. Pelos resultados apresentados, acredita-se que a proposta alcançou seus objetivos, uma vez que os estudantes conseguiram identificar, diferenciar e transferir o fenômeno das fases da Lua para novos contextos. Assim, conclui-se que uma metodologia com enfoque em um conteúdo significativo ao estudante é fundamental para a construção e compreensão genuína do que está sendo aprendido.

    This image is the clearest photo of Mexico City, Mexico taken from U.S. Manned Spacecraft. North is to the upper right. Mexico City sits in a basin surrounded by large volcanoes. The restricted atmospheric circulation in the basin, coupled with the inevitable air emissions produced by a city of 20 million people has created a critical air pollution problem for the city. In most photographs of the region, Mexico City is obscured by haze. The clarity of the photograph allows many key cultural features to be identified, including all of the major boulevards, the horse track (western part of the city), the university (south of the city), and the museum areas. Large, man-made ponds east of the city also stand out.

    Surgical education in Mexico basically follows the same model as in the United States, with a selection process resembling the matching program. There is a 4-year training period during which residents in their third year spend 4 months as the sole surgeon in a rural community. During the senior year they are entitled to an elective period in a place of their choosing. After completion of the 4 years, residents have to present a thesis and undergo an oral examination before getting a university diploma. They are then encouraged to pass the written and oral examination of the Mexican Board of Surgery before they are fully certified to enter practice in a public or private hospital.

    Collections were made during one year, between August 2005 and July 2006, in Malinalco, State of Mexico, in three sites of tropical deciduous forest, a pasture and a induced forest of pine-oak, established in a altitudinal gradient ranging from 1,253 m to 2,300 m. The total of 7,680 specimens Scarabaeidae, Silphidae and Trogidae were captured through NTP-80, representing 18 genera and 38 species. Onthophagus and Canthon contained 46% of the richness of Scarabaeidae. The more distant sites were complementary in their species composition. The lowest complementarity occurred between sites with tropical deciduous forest. It revises the material collected through pitffal traps and light traps funnel type, increasing the list of 38 to 50 species in the study area. Between 40% and 50% of the species in Malinalco are distributed in localities of the province of the basin Balsas and localities of the province of the Sierra Madre del Sur, and 30% in the localities of the province of Pacifica coast. For the first time 17 species of Scarabaeidae and three Trogidae were reported for the State of Mexico.

    A new species of Cogia A. Butler, 1870, is described from two localities ranging from 1470 to 2000 m elevation in the Sierra Madre del Sur of Oaxaca, Mexico; it occurs in cloud forest habitats and appears to be endemic to Mexico. Cogia buena, n. sp., is closely related to C. mala Evans, 1953 and C. aventinus (Godman & Salvin, 1894); these three species are the only known Cogia taxa whose males lack a hair tuft on the dorsal hindwing, and all have similar genitalia.

  1. Formaldehyde Surface Distributions and Variability in the Mexico City Basin

    NASA Astrophysics Data System (ADS)

    Junkermann, W.; Mohr, C.; Steinbrecher, R.; Ruiz Suarez, L.

    2007-05-01

    Formaldehyde ambient air mole fractions were measured throughout the dry season in March at three different locations in the Mexico City basin. The continuously running instruments were operated at Tenago del Aire, a site located in the Chalco valley in the southern venting area of the basin, at the Intituto Mexicano del Petroleo (IMP) in the northern part of the city and about 30 km north of the city at the campus of the Universidad Tecnològica de Tecamac (UTTEC). The technique used is the Hantzsch technology with a time resolution of 2 minutes and a detection limit of 100 ppt. Daily maxima peaked at 35 ppb formaldehyde in the city and about 15 to 20 ppb at the other sites. During night formaldehyde levels dropped to about 5 ppb or less. It is evident that the observed spatial and temporal variability in near surface formaldehyde distributions is strongly affected by local and regional advection processes.

    Rabies in dogs was unknown in the Americas before the arrival of the Spanish "Conquistadores". Until the mid-1980s rabies in animals and, in turn in humans, changed little from year to year, with the number of dog vaccinations reported annually rarely reaching one million. In Mexico, the national rabies control programme using mass parenteral vaccination of dogs started in 1990 with about seven million dogs vaccinated the same year. The number of vaccinated dogs exceeded 10 and 15 million in 1995 and 2005, respectively. Modern cell culture-based inactivated rabies virus vaccines were used. A key factor for the success of the dog rabies control program was the supply of potent canine rabies vaccines. Between 1990 and 2005, more than 150 million vaccine doses from 300 lots were administered. Each lot was tested for potency prior to use in the field. The required minimum content of rabies virus antigen for vaccines was 2 IU, in accord with WHO standards. Testing revealed antigen contents ranging from 3.28 to 5.59 IU. As a result of the mass dog vaccination campaigns, human rabies cases due to dog-mediated rabies decreased from 60 in 1990 to 0 in 2000. The number of rabies cases in dogs decreased from 3,049 in 1990 to 70 cases last year.

    Williams, Trevor; Arredondo-Bernal, Hugo C; Rodríguez-del-Bosque, Luis A

    2013-01-01

    Mexico is a megadiverse country that forms part of the Mesoamerican biological corridor that connects North and South America. Mexico's biogeographical situation places it at risk from invasive exotic insect pests that enter from the United States, Central America, or the Caribbean. In this review we analyze the factors that contributed to some highly successful past programs involving classical biological control and/or the sterile insect technique (SIT). The present situation is then examined with reference to biological control, including SIT programs, targeted at seven major pests, with varying degrees of success. Finally, we analyze the current threats facing Mexico's agriculture industry from invasive pests that have recently entered the country or are about to do so. We conclude that despite a number of shortcomings, Mexico is better set to develop biological control-based pest control programs, particularly on an area-wide basis, than many other Latin American countries are. Classical and augmentative biological control and SIT-based programs are likely to provide effective and sustainable options for control of native and exotic pests, particularly when integrated into technology packages that meet farmers' needs across the great diversity of production systems in Mexico.

    Medical Physics is an area that applies the principles of physics to medicine, particularly in the prevention, diagnosis and treatment of diseases using ionizing and nonionizing radiation. The main attractive of medical physics is that it has a direct impact on the quality and safety of medical care in humans; this social component with direct implications for the population is of high value for Mexico. This paper describes the concepts of medical physics, trends and the current status of this discipline as a profession, which is directly related to the efforts of clinical research. It is also described what is, in my opinion, the future of medical physics in Mexico, emphasizing the fact that this field requires a substantial boost from universities and hospitals to recruit highly qualified young medical physicists and the support from government agencies such as Secretaria de Salud, Instituto Mexicano del Seguro Social and Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado through clinical research projects that allow the necessary evolution of medical physics into the hospital setting.

    This study examines the history, current status and future prospects for increased coal use in Mexico. Environmental implications of the power-generation capacity expansion plans are examined in general terms. Mexican environmental law and regulations are briefly reviewed along with the new sense of urgency in the cleanup of existing environmental problems and avoidance of new problems as clearly mandated in recent Mexican government policy initiatives. It is expected that new capital facilities will need to incorporate the latest in process and technology to comply with existing environmental regulation. Technology developments which address these issues are identified. What opportunities have new initiatives caused by the recent diversification of Mexico`s energy economy offered US firms? This report looks at the potential future use of coal in the Mexican energy economy, examining this issue with an eye toward identifying markets that might be available to US coal producers and the best way to approach them. Market opportunities are identified by examining new developments in the Mexican economy generally and the energy economy particularly. These developments are examined in light of the current situation and the history which brought Mexico to its present status.

  1. Estudio teórico de moléculas de interés en Astrofísica: compuestos binarios policarbonados

    NASA Astrophysics Data System (ADS)

    Largo-Cabrerizo, A.

    Se han detectado en el espacio distintos compuestos binarios policarbonados (que se pueden formular como CnX), algunos de ellos con elementos de la primera fila del sistema periódico, pero también existen otros que contienen elementos de la segunda fila, como azufre o silicio. La información experimental sobre estos últimos compuestos es escasa, por lo que los estudios teóricos son especialmente valiosos en este campo. En esta comunicación presentaremos los avances mas recientes que sobre el tema ha realizado nuestro grupo. Incidiremos particularmente en dos aspectos. En primer lugar resumiremos los estudios en los que hemos intentado proporcionar información estructural sobre carburos metálicos formados por sodio, magnesio, aluminio o calcio, que pueda ser de ayuda a la hora de caracterizar estas moléculas en laboratorio como paso previo a su eventual detección en el espacio. Un aspecto importante dentro de este primer apartado es el análisis de las propiedades moleculares en función del tamaño del sistema (cuantificado en el numero de átomos de carbono) con el objeto de intentar sistematizar su estudio. En segundo lugar comentaremos brevemente algunos de los estudios realizados sobre posibles reacciones que pueden ser vías de síntesis de este tipo de compuestos en el medio interestelar.

  2. Anaglyph, Yucatan Peninsula, Mexico

    NASA Technical Reports Server (NTRS)

    2003-01-01

    This anaglyph (stereoscopic view) of Mexico's Yucatan Peninsula was generated entirely from Shuttle Radar Topography Mission (SRTM) data, and shows a subtle but distinctive indication of the Chicxulub impact crater. Most scientists now agree that this impact was the cause of the Cretatious-Tertiary extinction, the event 65 million years ago that marked the demise of the dinosaurs as well as the majority of life then on Earth. The crater's rim is marked by a shallow semicircular depression arcing about an offshore center point in the upper left of the picture. (The arcing depression is just above the blue line, when viewed with the naked eye.) This depression, or trough, only about 3 to 5 meters (10 - 15 feet) deep and about 5 kilometers (3 miles) wide, was likely caused by collapse of limestone caverns preferentially above the crater rim, resulting in an arcing chain of sinkholes. The limestone that covers most of the Yucatan Peninsula post-dates the impact crater. However, the crater pattern apparently controls the subsidence pattern just enough to show through.

    This anaglyph was created by deriving a shaded relief image from the SRTM data, draping it back over the SRTM elevation model, and then generating two differing perspectives, one for each eye. Illumination is from the north (top). When viewed through special glasses, the anaglyph is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter. The total relief (range of elevations) across this entire image is less than 300 meters (1000 feet).

    Elevation data used in this image were acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM

  4. Natural Hazards In Mexico City

    NASA Astrophysics Data System (ADS)

    Torres-Vera, M.

    2001-12-01

    Around the world more than 300 natural disasters occur each year, taking about 250,000 lives and directly affecting more than 200 million people. Natural hazards are complex and vary greatly in their frequency, speed of onset, duration and area affected. They are distinguished from extreme natural events, which are much more common and widespread, by their potential impacts on human societies. A natural disaster is the occurrence of a natural hazard on a large scale, involving great damage and, particularly in developing countries, great loss of life. The Basin of Mexico, whose central and southwestern parts are occupied by the urban area of Mexico City at the average altitude of 2,240 m above the sea level, is located on the southern edge of the Southern Plateau Central, on a segment of the Trans-Mexican Neovolcanic Belt that developed during Pliocene-Holocene times. The Basin of Mexico is a closed basin, which was created with the closing of the former Valley of Mexico because of basaltic-andesitic volcanism that formed the Sierra de Chichinautzin south of the city. The south-flowing drainage was obstructed and prompted the development of a lake that became gradually filled with sediments during the last 700,000 years. The lake fill accumulated unconformably over a terrain of severely dissected topography, which varies notably in thickness laterally. The major part of the urban area of Mexico City is built over these lake deposits, whereas the rest is built over alluvial material that forms the transition zone between the lake deposits and what constitutes the basement for the basin fill. In the present study, the effect of rain, fire and earthquakes onto Mexico City is evaluated. Rain risk was calculated using the most dangerous flood paths. The fire risk zones were determined by defining the vegetation areas with greater probability to catch fires. Earthquake hazards were determined by characterization of the zones that are vulnerable to damages produced by

  6. Aerosol Light Absorption and Scattering in Mexico City: Comparison With Las Vegas, NV, and Los Angeles, CA.

    NASA Astrophysics Data System (ADS)

    Paredes-Miranda, G.; Arnott, W. P.; Gaffney, J. S.; Marley, N. A.; Campbell, D.; Fujita, E.

    2007-12-01

    Aerosol light scattering and absorption measurements were deployed in and near Mexico City in March 2006 as part of the Megacity Impacts on Regional and Global Environments (MIRAGE). The primary site in Mexico City was an urban site at Instituto Mexicano del Petroleo (Mexican Oil Institute, denoted by IMP). Similar campaigns were held in Las Vegas, NV in January-February, 2003; and Los Angeles, CA at numerous sites during all seasons from 2003 through 2007. The IMP site gave in-situ characterization of the Mexico City plume under favorable wind conditions. The photoacoustic instrument (PAS) used at IMP operates at 532 nm, and conveniently allowed for characterization of gaseous absorption at this wavelength as well. Light scattering measurements are accomplished within the PAS by the reciprocal nephelometery method. In Mexico City the aerosol absorption coefficient typically varies between 20 and 180 Mm-1 during the course of the day and significant diurnal variation of the aerosol single scattering albedo was observed probably as a consequence of secondary aerosol formation. We will present the diurnal variation of the scattering and absorption as well as the single scattering albedo and fraction of absorption due to gases at the IMP site and compare with Las Vegas diurnal variation. Mexico City 'breaths' more during the course of the day than Las Vegas, Nevada in part because the latitude of Mexico City resulted in more direct solar radiation. Further insight on the meteorological connections and population dynamics will be discussed.

    2015-01-01

    Background Mexico is one of the six countries formerly endemic for onchocerciasis in Latin America. Transmission has been interrupted in the three endemic foci of that country and mass drug distribution has ceased. Three years after mass drug distribution ended, post-treatment surveillance (PTS) surveys were undertaken which employed entomological indicators to check for transmission recrudescence. Methodology/Principal findings In-depth entomologic assessments were performed in 18 communities in the three endemic foci of Mexico. None of the 108,212 Simulium ochraceum s.l. collected from the three foci were found to contain parasite DNA when tested by polymerase chain reaction-enzyme-linked immunosorbent assay (PCR-ELISA), resulting in a maximum upper bound of the 95% confidence interval (95%-ULCI) of the infective rate in the vectors of 0.035/2,000 flies examined. This is an order of magnitude below the threshold of a 95%-ULCI of less than one infective fly per 2,000 flies tested, the current entomological criterion for interruption of transmission developed by the international community. The point estimate of seasonal transmission potential (STP) was zero, and the upper bound of the 95% confidence interval for the STP ranged from 1.2 to 1.7 L3/person/season in the different foci. This value is below all previous estimates for the minimum transmission potential required to maintain the parasite population. Conclusions/Significance The results from the in-depth entomological post treatment surveillance surveys strongly suggest that transmission has not resumed in the three foci of Mexico during the three years since the last distribution of ivermectin occurred; it was concluded that transmission remains undetectable without intervention, and Onchocerca volvulus has been eliminated from Mexico.

  15. Geothermal Fields on the Volcanic Axis of Mexico

    SciTech Connect

    Mercado, S.; Gonzalez, A.

    1980-12-16

    At present in Mexico, geothermal energy is receiving a great impulse due to the excellent results obtained in the Cerro Prieto geothermal field, in which a geothermoelectric plant is operated. This plant has four units of 37.5 MW each, with a total capacity of 150 MW, and under program 470 MW more by 1984. The Government Institution, Comisi6n Federal de Electricidad, is in charge of the exploration and exploitation of geothermal fields as well as construction and operation of power plants in Mexico. By this time CFE has an extensive program of exploration in the central part of Mexico, in the Eje Neovolcdnico. In this area, several fields with hydrothermal alteration are under exploration, like the Michoac6n geothermal area, where Los Azufres geothermal field is being developed. Seventeen wells have been drilled and twelve of them presented excellent results, including two dry steam wells. In other areas, such as Arar6, Cuitzeo, San Agustln del Maiz,Ixtldn de Los Hervores and Los Negritos, geological, geophysical and geochemical explorations have been accomplished, including shallow well drilling with good results. Another main geothermal area is in the State of Jalisco with an extension of 5,000 m2, where La Primavera geothermal field shows a lot of volcanic domes and has an intensive hydrothermal activity. Deep wells have been drilled, one of them with a bottom temperature of 29OOC. Other fields in this area, like San Narcos, Hervores de La Vega, La Soledad, Villa Corona, etc., have a good geothermal potential. A new geothermal area has been explored recently in the eastern part of the country named Los Humeros, Puebla. In this area studies are being made and there are plans for well drilling exploration by the beginning of 1981. Like this one, there are many other areas in the country in which 300 hydrothermal alteration zones are been classified and 100 of them are considered economically exploitable.

  16. Asthma and geographical altitude: an inverse relationship in Mexico.

    PubMed

    Vargas, M H; Sienra-Monge, J J; Díaz-Mejía, G; DeLeón-González, M

    1999-09-01

    Motivated by the great asthma-prevalence variation throughout the world, we analyzed the rate variation of medical services due to asthma in the 32 Mexican states at the Instituto Mexicano del Seguro Social (approximately 24 million insured subjects). In 1993, a total of 406,036 services were due to asthma, and state rates ranged from 53 to 476 x 10,000 insured subjects. A direct correlation (p < 0.05) was found for single-room house, ascariasis, and rubella rates, but the strongest (inverse) correlation was found for geographical altitude (r = -0.73, p < 10(-5)). Thus, in Mexico, geographical altitude affects the etiological factor(s) responsible for the development of asthma or for the triggering of asthma attacks.

    2017-01-01

    Introducción: el fosfuro de zinc es usado para exterminar roedores; es un producto altamente tóxico, no crea resistencias y es de uso popular. Debido a que es un plaguicida altamente comercializado de elevada toxicidad que no cuenta con un antídoto disponible, es imperativo precisar e identificar con oportunidad las manifestaciones clínicas de la intoxicación. El objetivo fue describir el perfil epidemiológico y clínico de los niños intoxicados con fosfuro de zinc atendidos en un centro toxicológico de tercer nivel de atención. Métodos: estudio retrospectivo, observacional y trasversal del 2005 al 2015, con 36 registros de pacientes pediátricos atendidos en el Centro de Información y Atención Toxicológica del Hospital General “Dr. Gaudencio González Garza” del Centro Médico Nacional La Raza del Instituto Mexicano del Seguro Social. Resultados: el estudio no demostró predominio de algún género. El 66% de los pacientes se encontraba entre 1 y 2 años de edad. El 96% de los pacientes eran sanos y tres adolescentes utilizaron el producto con fines suicidas. La exposición ocurrió en el hogar. La toxicidad se caracterizó por hipotensión arterial, hipoglucemia, acidosis metabólica, dolor abdominal, náuseas, vómitos; ninguno de los pacientes falleció ni requirió de asistencia ventilatoria ni de hemodiálisis. Conclusión: la falta de conocimiento del potencial tóxico y la accesibilidad al producto en el interior del domicilio de los pacientes facilita su exposición; se trata de un riesgo 100% prevenible.

  18. Mexico`s economic reform: Energy and the Constitution

    SciTech Connect

    Rubio, L.

    1993-12-31

    Oil is a fundamental component of nationhood in Mexico. The 1938 expropriation of oil resources concluded a process of internal political consolidation and thus became the most important symbol of nationalism. Mexico has been undergoing a process of economic reform that has altered the country`s economic structure and has subjected it to international competition. Oil in particular and energy in general have been left untouched. There is recognition that without an equal reform of the energy industry, the potential for success will be significantly limited. While the Constitution allows private investment in the industry--with the exception of the resource properties themselves--the Regulatory Law bans any private participation. Because of its political sensitivity, however, amending the law in order to reform the oil industry will necessitate a domestic initiative rather than foreign pressure. In this perspective, NAFTA served to slow and postpone the reform of the industry, rather than the opposite. Once NAFTA is well in place, the industry will have to face competition.

  19. SANDIA MOUNTAIN WILDERNESS, NEW MEXICO.

    USGS Publications Warehouse

    Hedlund, D.C.; Kness, R.F.

    1984-01-01

    Geologic and mineral-resource investigations in the Sandia Mountains in New Mexico indicate that a small part of the area has a probable mineral-resource potential. Most of the mineral occurrences are small barite-fluorite veins that occur along faults on the eastern slope of the range. The barite veins in the Landsend area and in the Tunnel Spring area are classed as having a probable mineral-resource potential. Fluorite veins which occur at the La Luz mine contain silver-bearing galeana and the area near this mine is regarded as having a probable resource potential for silver. No energy resources were identified in this study.

    NASA Astrophysics Data System (ADS)

    Cirigliano, D.; Rovira, M.; Mauas, P.

    En este trabajo presentamos perfiles de líneas del CaII, MgII y HeI calculados para distintos modelos de protuberancias, y los comparamos con observaciones obtenidas por los satélites OSO 8 y SOHO. Para obtener las poblaciones de los distintos niveles de los átomos, utilizamos un código numérico que combina las ecuaciones de transporte de radiación y equilibrio estadístico en un único sistema de ecuaciones no lineal. Los modelos básicos que consideramos para las protuberancias consisten en placas homogéneas y unidimensionales apoyadas sobre la superficie del Sol. Dichas placas se hallan estratificadas en hebras y los modelos difieren entre sí en la temperatura y ancho de la placa, en la presión a la cual se halla el plasma y en el número de hebras. A partir de estos modelos se investiga cada uno de estos parámetros libres y como influyen en la atmósfera de las protuberancias solares y en el perfil de línea de cada especie estudiada, con el objetivo de determinar las condiciones en las que se halla el material atmosférico de estas protuberancias.

  12. Human and remote sensing data to investigate the frontiers of urbanization in the south of Mexico City.

    PubMed

    Rodriguez Lopez, Juan Miguel; Heider, Katharina; Scheffran, Jürgen

    2017-04-01

    The data presented here were originally collected for the article "Frontiers of Urbanization: Identifying and Explaining Urbanization Hot Spots in the South of Mexico City Using Human and Remote Sensing" (Rodriguez et al. 2017) [4]. They were divided into three databases (remote sensing, human sensing, and census information), using a multi-method approach with the goal of analyzing the impact of urbanization on protected areas in southern Mexico City. The remote sensing database was prepared as a result of a semi-automatic classification, dividing the land cover data into urban and non-urban classes. The second data set details an alternative view of the phenomena of urbanization by concentrating on illegal settlements in the conservation zone. It was based on voluntary complaints about environmental and land use offences filed at the Procuraduria Ambiental y del Ordenamiento Territorial del Distrito Federal (PAOT), which is a governmental entity responsible for reviewing and processing grievances on five basic topics: illegal land use, deterioration of green areas, waste, noise/vibrations, and animals. Anyone can file a PAOT complaint by phone, electronically, or in person. The complaint ends with a resolution, act of conciliation, or recommendation for action by other actors, such as the police or health office. The third data about unemployment was extracted from Mexico׳s National Census 2010 database available via public access.

    1994-04-01

    The objective of this cross-sectional study was to estimate mortality and morbidity from asthma in Mexico by federative entity (state) of residence, age, and sex during the period between 1960 and 1988. Statistics published by the National Institute of Statistics, Geography, and Information Science were reviewed, as were vital statistics and information from other sources. Data were selected on mortality, hospital admissions, and outpatient visits, as well as population by federative entity, age, and sex. Mortality and morbidity rates were adjusted for age using the direct method. From 1960 to 1987, mortality decreased for both sexes. The groups with the highest asthma mortality were those under 4 years of age and those over 50. From 1960 to the present, the state with the highest mortality was Tlaxcala. Hospitalizations increased from 10 to 140 per 100,000 population for the country as a whole. When both outpatient visits and hospitalizations were considered, the morbidity rates rose from 180 to 203.4 per 100,000 between 1960 and 1970. In 1970, hospital morbidity was higher among males than females. From 1960 up to the 1990s, the highest rates of hospitalization and outpatient visits were registered among those under 4 and those over 60. The states with the highest asthma hospitalization rates were Morelos, Baja California Sur, Nuevo León, Durango, and Tamaulipas. It is concluded that asthma mortality in Mexico is showing a downward trend, while morbidity is increasing considerably, especially among adolescents.

  15. Estudio de un microcable de par trenzado para la comunicacion y lectura del modulo de pixeles del experimento CMS

    NASA Astrophysics Data System (ADS)

    Oliveros Tautiva, Sandra Jimena

    The Compact Muon Solenoid (CMS) is one of the two most important experiments at the Large Hadron Collider (LHC). The pixel detector is the component closest to the collision in CMS and it receives large doses of radiation which will affect its performance. The pixel detector will be replaced by a new one after four years. The aim is to reduce material in the sensitive zone of the new pixel detector, which leads to the implementation of a type of micro twisted pair cable that will replace the existing kapton cables and some connections will be eliminated. The purpose of this work was to study the viability of using these micro twisted pair cables in the existing 40 MHz analog readout. The electrical parameters of micro cables were determined, and operational tests were performed in a module using these cables for communicating and reading. Three different lengths of micro cables were used, 1.0, 1.5 and 2.0 m, in order to compare test results with those obtained using the kapton cable. It was found that the use of these cables does not affect the programming and reading of the pixels in one module, so the micro cables are viable to be used in place of the kapton cables.

    Los cúmulos abiertos muy jóvenes proveen valiosa información sobre las teorías de evolución estelar. No obstante, no se conoce mucho sobre los miembros mas débiles de estos objetos. Se llevaron a cabo entonces, estudios detallados (fotometría CCD-UBVI y polarimetría) en los cúmulos abiertos: Tr 14, Cr 272, Stok 16, NGC 6231, NGC 3293 y HM 1. Se realizó entonces un análisis comparativo entre ellos y con los objetos Pismis 20 (Vázquez et al. 1995) y NGC 5606 (Vázquez et al. 1994). En particular, se analizó la secuencia principal inferior de los distintos cúmulos, se estudió la extinción interestelar y las propiedades del polvo, se determinaron las correspondientes IMF, y se estudió la forma en que se distribuyen las estrellas menos masivas en relación con las más masivas. Como conclusiones del trabajo se puede decir que se han redeterminado con mayor precisión las distancias y las edades de los objetos bajo estudio, se han hallado varias estrellas con alta probabilidad de estar en fase de contracción y se ha notado una dispersión de edad entre las estrellas más brillantes y las menos brillantes (confirmando la idea de que la formación estelar no es simultánea ni independiente de la masa). Además, se han encontrado que las pendientes de las IMFs de estos objetos son más planas que la de las estrellas de campo y las de cúmulos más evolucionados, siendo comparable con las halladas en objetos jóvenes de la Nube Mayor de Magallanes (Will et al. 1996).

    On 16 June, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force released an action plan to reduce, mitigate, and control hypoxia in the northern Gulf of Mexico. The plan builds upon a 2001 plan by including more accountability through an annual operating plan, better tracking of progress, and state and federal nutrient reduction strategies. ``Our improved plan unites governments and citizens across the country to take action upstream and along the coast to reduce river nutrient pollution and increase Gulf of Mexico health,'' said U.S. Environmental Protection Agency assistant administrator for water Benjamin Grumbles.

    In this work; we present a multi-wavelength study of the bipolar molecular outflow associated with the VLA 1623 proto-star (age 10 yrs). We analyze images obtained by Spitzer as well as other images from the literature. We identify 32 H (2.12 m) emission knots and 25 objects predominantly emitting in the [4.5] m band; usually known as EGOs (Extended Green Objects). Seven of these emissions are new EGO candidates; five of which have 2.12 m counter-parts. We compare the morphology of the emissions at 2.12 m and [4.5] m with the bipolar molecular outflow; finding an excellent agreement. The emissions are quasi-regularly spaced. We determine a dynamical time of 194.3 yrs between consecutive knots; which agrees with the lapse of time between eruptive FU Orionis events. This suggests that events of this type experimented by the central source might be the cause of the intermittency in the detected emissions. FULL TEXT IN SPANISH

    The school health program in Mexico, directed by the Office of School Hygiene (la Unidad de Higiene Escolar), is in a state of flux. The program will change substantially if an initiative between the national offices of health and education is enacted. The initiative would establish a national commission to be replicated at state, county, and district levels. Commissions would oversee integration of the health services component, social participation, and research into the school health program which currently only focuses on health instruction and a healthy school environment. The initiative would restore and improve a former model that incorporated health services as a part of the school health program. The history of the school health program, which can trace its roots to 1861 and President Benito Juarez, is provided.

    1915 was a terrible year for Mexican people. After dictator Huerta’s fall, fratricide fighting involved diverse revolutionary groups. Mexico City was assaulted and occupied successively by different armies and, following the war came hunger and epidemics. Many people died from starvation, 30 to 40 every day in July and August. In this paper I review the medical texts written by physicians involved in the treatment of these patients. The main were E. Landa, M. Torroella and F. de P. Miranda and all of them concurred in the observation of important edema increasing to become generalized, important anemia and a watery aspect of the blood, facts that determine the term edema employed to characterize this disease.

    In the last 17 years, health policy in Mexico has been shifted from a conception of integrated health care and a gradually extended coverage as a major responsibility of the State and health care public institutions, to in the one hand, a very active promotion of market and private profit in health services and in the other, poverty relief programs. In this paper we identify different periods corresponding to the last three presidential terms. Each clearly represent different stages of health sector reform: transitional (1982-1988), mercantilisation and poverty relief (1988-1994) and, strengthening of the so called health markets (1994-2000). The analyzed transformation is part of the set of secondary reforms subordinated to the structural adjustment and the economic and social megaprojects imposed by the international financial institutions.

    West Nile virus (WNV) has caused disease in humans, equids, and birds at lower frequency in Mexico than in the United States. We hypothesized that the seemingly reduced virulence in Mexico was caused by attenuation of the Tabasco strain from southeastern Mexico, resulting in lower viremia than that caused by the Tecate strain from the more northern location of Baja California. During 2006-2008, we tested this hypothesis in candidate avian amplifying hosts: domestic chickens, rock pigeons, house sparrows, great-tailed grackles, and clay-colored thrushes. Only great-tailed grackles and house sparrows were competent amplifying hosts for both strains, and deaths occurred in each species. Tecate strain viremia levels were higher for thrushes. Both strains produced low-level viremia in pigeons and chickens. Our results suggest that certain avian hosts within Mexico are competent for efficient amplification of both northern and southern WNV strains and that both strains likely contribute to bird deaths.

    MR imaging has experienced an important growth worldwide and in particular in the USA and Japan. This imaging technique has also shown an important rise in the number of MR imagers in Mexico. However, the development of MRI has followed a typical way of Latin American countries, which is very different from the path shown in the industrialised countries. Despite the fact that Mexico was one the very first countries to install and operate MR imagers in the world, it still lacks of qualified clinical and technical personnel. Since the first MR scanner started to operate, the number of units has grown at a moderate space that now sums up approximately 60 system installed nationwide. Nevertheless, there are no official records of the number of MR units operating, physicians and technicians involved in this imaging modality. The MRI market is dominated by two important companies: General Electric (approximately 51%) and Siemens (approximately 17.5%), the rest is shared by other five companies. According to the field intensity, medium-field systems (0.5 Tesla) represent 60% while a further 35% are 1.0 T or higher. Almost all of these units are in private hospitals and clinics: there is no high-field MR imagers in any public hospital. Because the political changes in the country, a new public plan for health care is still in the process and will be published soon this year. This plan will be determined by the new Congress. North American Free Trade Agreement (NAFTA) and president Fox. Experience acquired in the past shows that the demand for qualified professionals will grow in the new future. Therefore, systematic training of clinical and technical professionals will be in high demand to meet the needs of this technique. The National University (UNAM) and the Metropolitan University (UAM-Iztapalapa) are collaborating with diverse clinical groups in private facilities to create a systematic training program and carry out research and development in MRI

    In Mexico, a 40 year period of political stability and economic advancement, hailed for its high rates of growth in income per capita, rapid urbanization, and impressive gains in indicators of health and education, seemed to come to a halt in the early 1980s. Since the early 1970s, fertility has declined sharply in chronological association with a new population policy and the implementation of a national family planning program. If in 1940 there was no apparent reason for the Mexican state to have much interest in limiting fertility, such was no longer the case by 1970. The General Law of Population that had been passed in 1947 was laced with the expansionist ideology that dominated demographic issues for more that a century; its pro-natalism had been reinforced by health regulations prohibiting the sale and use of contraceptives and by a penal code that made abortion a crime. Between 1970 and 1981 the total fertility rate fell by about 39%. Since 1975, change in contraceptive practice accounts for the bulk of the measured fertility decline. Between 1976 and 1982 there was a 66% increase in contraceptive prevalence. The government's involvement in family planning activities helped to: 1) develop an effective contraceptive distribution system; 2) circulate extensive information, education, and communication publicizing fertility and images of the small family; and 3) mobilize health practitioners in public institutions to counsel and persuade their clients to accept and practice contraception. The emerging debate over population policy in Brazil may well prefigure debates in other Latin American countries; the recent democratization in Brazil is the vocalization of a demand from women's groups and the left for government provided family planning services. Overall, Mexico's willingness to take the long view tackle the birth rate issue head on is likely to remain an exception in Latin America.

  1. Extending U.S. Medicare to Mexico

    Haims, Marla C.; Dick, Andrew W.

    2012-01-01

    Abstract There is a lack of hard data on the exact number of Medicare-eligible retirees residing in Mexico, but it is at least in the tens of thousands and is certainly rising as the baby boom generation reaches retirement. Because Medicare does not cover health services received outside the United States, these retirees must travel to the United States for health care or purchase alternative coverage for health services received in Mexico. There are several arguments for extending Medicare to Mexico—that is, allowing Medicare-eligible beneficiaries to receive their Medicare benefits in Mexico. Medicare-eligible retirees living in Mexico would certainly benefit, and Mexico might benefit from improved quality of care and an expanded health economy. Moreover, American taxpayers might benefit from a reduced total cost of Medicare: To the extent that extending Medicare to Mexico induces Medicare beneficiaries to substitute higher-cost U.S. health care services with lower-cost Mexican services, overall Medicare expenditures might be reduced. The authors outline four options for how this policy change might be implemented and describe a conceptual model that could be used to assess the effects of each option. PMID:28083264

    There is a lack of information concerning the history of soil science in developing countries such as Mexico. Soil knowledge in the pre-Colombian era was a notable attribute of indigenous people in Mexico. Mayas and Aztecs classified soils based on properties and land use and developed a terminology still used by locals. International organizations and institutions advocating modern agricultural practices have played an important role in the development of soil science in Mexico, in conjunction with the Green Revolution in which the use of fertilizers for crop production was implemented. Soil fertility, as an area of study, has developed significantly in the country. One of the most significant impacts of the Green Revolution on the development of soil science in Mexico was through academic exchange, in which Mexican soil scientists obtained graduate-level degrees in the United States and later returned to Mexico to conduct research programs. Although Mexico has a long history of soil knowledge, soil scientists are facing several challenges today, including a lack of communication between farmers and scientists, soil erosion, soil contamination, and water usage. Some researchers have suggested that ethnopedological knowledge should be incorporated into modern Mexican soil science.

    El estudio de la actividad solar con el telescopio para ondas submilimétricas (SST), nos permite, por vez primera, trabajar con una resolución temporal de milisegundos. Este hecho ha permitido observar emisión nunca antes comprobada, pulsos o flashes extremadamente rápidos provenientes de las regiones activas, los cuales parecen preanunciar fulguraciones en dichas regiones. Se muestra, como ejemplo, una fulguración observada con el telescopio HASTA en Hα, y los pulsos rápidos que la preceden observados con el SST. Para cuantificar la influencia de la atmósfera terrestre en los datos registrados, se está estudiando la variabilidad temporal de las opacidades a las frecuecias de trabajo (212 y 405 Ghz), es decir los rangos de tiempo para los cuales la opacidad puede variar apreciablemente. Con este fin se calcula la eficiencia de cada canal multiplicada por la temperatura del Sol a estas frecuencias (estas son conocidas con una incerteza del 20 %). Se muestran los resultados obtenidos para cada canal, en donde se grafica este producto como función de la opacidad.

    Introducción: La incidencia del cáncer de piel en México se ha incrementado en los últimos años. La radiación UV es el principal factor de riesgo asociado. Debido a la necesidad de desarrollar estrategias para evitarla, el objetivo del estudio fue estimar la intensidad UV en diversas regiones representativas del país, la dosis UV promedio anual de esas poblaciones y el beneficio potencial de la aplicación de un filtro solar a diferentes edades. Métodos: se cuantificó la intensidad de la radiación UV mediante radiometría terrestre y remota. La dosis de exposición UV se midió en dosis mínimas eritematógenas utilizando modelos validados para cara y brazos. El beneficio de realizar fotoprotección se calculó para el uso de un filtro con FPS 15 desde el nacimiento hasta los 70 años. Resultados: la radiación UV es menor en diciembre y máxima de mayo a julio. La localidad con menor dosis anual es Tijuana y la máxima el Distrito Federal. La diferencia anual entre estas regiones es de 58 %. Durante la vida, un filtro solar de baja potencia puede reducir hasta 66 % la dosis recibida. Conclusiones: la localización geográfica es un factor de riesgo para la acumulación de radiación UV en México. Desde la infancia, la población recibe dosis elevadas de radiación UV. La mayoría de esas dosis puede reducirse mediante cualquier filtro solar disponible en el comercio, si es aplicado de forma estratégica.

    Four vertebrate biochrons can be recognized in Late Triassic strata of New Mexico: (A) Metoposaurus-Rutiodon-Desmatosuchus-Calyptosuchus-Placerias occurs in the Los Esteros member of the Santa Rosa formation near Lamy and is less well known from the lower Petrified Forest Member of the Chinle Formation near San Ysidro, at Mesa del Oro, near Fort Wingate, at Ojo Huelos, and in the Joyita hills. (B) Anaschisma-Belodon-Typothorax-Desmatosuchus-Paratypothorax occurs in the lower Bull Canyon formation in Bull Canyon and near Tucumcari, in the Trujillo Formation near Tucumcari, and possibly in the Travesser Formation of the Dry Cimarron valley, the Petrified Forest Member near Carthage, and the Garita Creek formation near Lamy and Conchas Lake. (C) Anaschisma-Belodon-Typothorax occurs in the upper Bull Canyon formation in Bull Canyon, in the upper Petrified Forest Member near San Ysidro, at Ghost Ranch, near Albuquerque (Correo Sandstone Bed), and possibly in the Sloan Canyon Formation of the Dry Cimarron valley. (D) Anaschisma-new phytosaur, cf. Typothorax-new sphenosuchian, occurs in the Redonda Formation near Tucumcari. The biochronologic ranges of significant vertebrate taxa within New Mexico follow: metoposaurs - Metoposaurus (A-B ), Anaschisma (B-D); phytosuars - Rutiodon (A), Belodon (B-C), new taxon (D); aetosaurs - Calyptosuchus (A), Desmatosuchus (A-B), Paratypothorax (B), Typothorax (B-D ); rauisuchians - Postosuchus (A-B), Chatterjeea (B-C); sphenosuchians - new taxon 1 (A), Hesperosuchus (B), new taxon 2 (D); dinosaurs - ornithischians (B), Coelophysis (C), other theropods (B-C); therapsids - Placerias (A), Pseudotriconodon (C). Biochron A may be Carnian in age, whereas biochrons B-D are probably early to middle ( ) Norian.

    With financing of the British Government and support of the National Institute of Ecology, from April of 2006 to March of 2008 an action plan which intends variability effects and climatic change for the state of Veracruz will be made. This plan will be taken to the state government and will be spread out to manufacturers, industrialists and population. Throughout the Gulf of Mexico, the state of Veracruz is a 745 km coast in length with a width that goes from 156 km in the center to 47 km in the north. The state has large mountains, forests, plains, rivers, cascades, lagoons and coasts. Veracruz is the 10th largest state in Mexico with a 72,420 km2 surface, it is located between 17°00' and 22°28' north latitude and between 93°95' and 98°38' west longitude. Because of the orographic effect, the Sierra Madre Oriental causes the existence of many types of climate, from dry to tropical forest, going through snow on the top of the Pico de Orizaba (5747m of altitude). The wind affects the coasts by not allowing to fish during a hundred days a year (particularly in winter), and on summer tropical waves and occasionally hurricanes affect rivers causing overflow and urban floods in fields. These phenomena do not have a regular affectation; they are subject to climate variability effects. Veracruz is the third state with most population in the country (7.1 million people in 2005), only surpassed by the state of Mexico and Mexico City. Although it occupies 3.7% of the national territory, Veracruz has 6.9% of human population in the country, and is the 6th state of PIB national contribution (240 thousands of millions pesos approximately). Of the possible effects of the climatic change the following can be expected: , , : Most of the coasts of the Gulf of Mexico, low and sandy, less of a meter on the sea level, represent the most vulnerable territory of Veracruz. Towns will be affected, the saline water will infiltrate until the phreatic mantles and the coast electrical

    Mexico is a Country characterized by its diversified means of Power Gerneration. Actual installed capacity is almost 19000 MW, of which 205 MW corresponds to Geothermal Plants, that is, 180 MW in Cerro Prieto and 25 MW of Portable Plants in Los Azufres. To date, 346 area with exploitation possibilites, are known. They are mainly distributed along the Volcanic Belt where the most prominent are, Los Azufres, La Primavera, Los Humeros, Ixtlan De Los Hervores and Los Negritos, among others. Proved reserves are 920 MW, and the accessible resource base are 4600 MW identified and 6000 MW undiscovered. The long range construction studies intends to achieve a total installed capacity of 100000 MW, by the end of this century, including 2000 MW Geothermal, through conventional and Portable Plants. It is not a definite program but a development strategy. The carrying out of a definite program, will depend upon the confirmation of Hypothesis made in previous studies, and the economic decisions related to the financial sources availability, and techologies to be used in the future as well.

    2010-09-17

    Since the early 1990s, Los Alamos National Laboratory (LANL) has applied electric grid models and simulation software to problems of national significance. This effort continues with a variety of other projects funded by the Department of Energy (DOE), other federal and state agencies and private companies. Critical to the success of these programs is the ability to integrate regional-scale models of the electric grid, to assess the propagation of grid impacts, and to present interactively the effect of potential mitigating actions required to stabilize the grid. All of these capabilities are applied in this study, to accomplish the following goals and objectives: (1) Develop an AC power flow model representing future conditions within New Mexico's electric grid, using commercial tools accepted by the utility industry; (2) Conduct a 'screening' analysis of options for accelerating potential renewable energy development through the addition of a statewide transmission collector system; (3) Estimate total revenue needed, jobs created (temporary and permanent) plus indirect and direct impacts to the state's economy; (4) Evaluate potential cost allocation methodology; and (5) Issue a project report that will provide information for policy direction by state regulators, project developers, and legislators.

    Prevalence of antibodies against Giardia duodenalis was determined by enzyme-linked immunosorbent assay in serum samples from a national serologic survey of Mexico that included all geographic areas and socioeconomic and demographic data for each person sampled. The country was divided into four regions on the basis of development (high, medium high, medium low, and low). Of 3,461 serum samples tested, 1,914 (55.3%) were positive for IgG antibodies against Giardia duodenalis. Seropositivity was age-specific; the probability of seropositivity increased 4.9-fold (95% confidence interval [CI] = 3.16-7.64) in adolescents 10-19 years of age, 8.0-fold (95% CI = 5.19-12.53) in young adults 20-39 years of age, and 12.6-fold (95% CI = 7.93-20.28) in adults more than 40 years of age. Giardia duodenalis seropositivity was associated with male sex (odds ratio = 1.40, 95% CI = 1.22-1.61). No association was found between seropositivity and socioeconomic variables or regional development status.

    The Ediacaran biota is the earliest diverse community of macroscopic animals and protoctists. Body and trace fossils in the Clemente Formation of northwestern Sonora extend downward the geologic range of Ediacaran forms. Taxa present in the Clemente Formation include cf. Cyclomedusa plana, Sekwia sp., an erniettid (bearing an air mattress-like "pneu" body construction), and the trace fossils Lockeia ichnosp. and Palaeophycus tubularis. The trace fossils confirm the presence of sediment-dwelling animals in this shallow marine community. The body fossils are headless, tailless, and appendageless. Some may be body fossils of animals but others may be fossils of large protoctists. These body and trace fossils, recovered from thinly bedded sandstones and siltstones, occur 75 meters lower in the Sonoran stratigraphic section than a distinctive Clemente Formation oolite. The stratigraphic position of the fossils below this oolite permits long-distance correlation between fossiliferous Proterozoic strata of Mexico and the United States. Correlations utilizing both the Clemente Formation oolite and a trace fossil (Vermiforma antiqua) confirm the antiquity (600 million years or more) of this body fossil-rich community of macroscopic eukaryotes. The recently discovered body fossils are the oldest known remains of the Ediacaran biota. Images Fig. 2 PMID:11607679

    The Ceboruco is a late Quaternary dacitic-andesitic stratovolcano, is located in the Tepic-Zacoalco graben in the western part of the Trans-Mexican Volcanic Belt (TMVB) near to Ahuacatlan and Jala towns in Mexico. There have been at least eight eruptions from this volcano in the last thousand years, and for this reason Ceboruco must be considered an active volcano whit the possibility of erupting again in the future. This work aims to contribute with a regional density contrasts model from gravity measurements of volcano area. 163 observations were measured every 500 meters with a Scintrex CG-5 gravimeter. We corrected data were measured in the area to filter information dependent of external gravitational fields or outside to object of study. Post-filtering of data, we obtained gravity anomalies distribution and with other supporting data (aeromagnetic and geological data) we made 8 profiles around Ceboruco to build an approximate model of density changes in the lithological units under the volcano.

    2009-11-01

    Cosmic ray research in Mexico dates from the early 1930s with the work of the pioneering physicist, Manuel Sandoval Vallarta and his students from Mexico. Several experiments of international significance were carried out during that period in Mexico: they dealt with the geomagnetic latitude effect, the north-south and west-east asymmetry of cosmic ray intensity, and the sign of the charge of cosmic rays. The international cosmic ray community has met twice in Mexico for the International Cosmic Ray Conferences (ICRC): the fourth was held in Guanajuato in 1955, and the 30th took place in Mérida, in 2007. In addition, an international meeting on the Pierre Auger Collaboration was held in Morelia in 1999, and the International Workshop on Observing UHE Cosmic Rays took place in Metepec in 2000. A wide range of research topics has been developed, from low-energy Solar Energetic Particles (SEP) to the UHE. Instrumentation has evolved since the early 1950s, from a Simpson type neutron monitor installed in Mexico City (2300 m asl) to a solar neutron telescope and an EAS Cherenkov array, (within the framework of the Auger International Collaboration), both at present operating on Mt. Sierra La Negra in the state of Puebla (4580 m asl). Research collaboration has been undertaken with many countries; in particular, the long-term collaboration with Russian scientists has been very fruitful.

  2. Growth through conservation: DSM in Mexico

    Rodriguez, I.; Wolcott, D.

    1993-08-01

    Mexico's electricity consumption is expected to grow at an average annual rate of about 6 percent between 1992 and 2000; a slightly higher growth rate is anticipated in the industrial sector. To meet this demand, the Comision Federal de Electricidad (CFE), Mexico's national utility, plans to build almost 14,000 MW of additional generating capacity, which is to come on line between 1993 and 2000 at an estimated cost of US $34 billion (including additional transmission and distribution investments). In 2000, such a capacity expansion would represent a 78-percent increase over 1990. As a result, CFE faces substantial increases in its external indebtedness in the 1990s, and unattractive option for a utility that had already accumulated nearly $1 billion in external debt as of the end of 1991. Significant growth in CFE's indebtedness would represent a setback for a nation that has worked diligently over several years to contain and reduce nearly unmanageable levels of external public-sector debt. Additionally, there are large, competing capital requirements in Mexico for other public services, such as roads, water, and sewage systems. It is in this context that Mexico is considering alternatives to the conventional approach to capacity expansion and is exploring a complementary alternative: demand-side management (DSM). Compared to other countries in Latin America, Mexico is well ahead in implementing both innovative tariff mechanisms and pilot projects.

    The recent Shell Oil Co.-led exploratory well in 7,000 ft of water in the Gulf of Mexico off Brownsville, Texas, and close to Mexican territory, initially provoked a controversy in Mexico. The announcement of the Baha well reminded Mexicans that the US Senate has not yet ratified the draft treaty to define territorial and resource boundaries. News of the well was portrayed in mexico as poaching and old-fashioned American imperialism. Although subsequent reports confirmed that the well is unequivocally in US waters, the initial confusion added to a growing dilemma in professional geological circles and with a few federal, state, and local officials. In this discussion, which is part of a larger study, the authors wish to clarify some of the issues in the upstream policy debate in Mexico. They do this by visualizing a counter-factual condition: that worldwide E and P patterns and norms exist in Mexico. The discussion will not treat the implementation of such patterns or norms (e.g., by reference to the Venezuelan or Argentine models). For this discussion they assume simply that worldwide production practices and agreements exist in Mexico. Just as important, they assume that industrial efficiencies, by producer type, are the principal drivers of the allocation of E and P resources in Mexico. The authors discuss the illustrative areas and fields of hydrocarbon production, actual and potential, from the perspective of the advantages and limitations associated with the various categories of explorationists and producers.

    Cremation was a part of the funeral ceremony in prehispanic Mexico. When the Spanish conquerors came, this practice was prohibited. In 1877, the Uppu Health Council authorized animal incineration to avoid consumption by indigents or transformation in putrid emanation. Creamation was welcome in Mexico because of the knowledge of hygienic at the time, whose adepts had evaluated toxic exhalations of cadavers and the cemeteries of Mexico City, with incomplete destruction of the cadaver and filtration of contaminants into the subsoil. Three were the reasons against cremation; religious beliefs, lawmaker medical preoccupation with the disappearance of legal evidence, and the newly born science of anthropology, with loss of material for laboratory. The first crematorium was inaugurated by Dr. Eduardo Liceaga in February 1909 in the Dolores Cemetery.

    Los Alamos National Laboratory, as part of the New Mexico Consortium - comprised of New Mexico's major research universities, the Lab, and key industry partners - is conducting research into using algae as a feed stock for a renewable source of fuels, and other products. There are hundreds of thousands of different algae species on Earth. They account for approximately half of the net photosynthesis on the planet, yet they have not been used in any kind of a large scale by humanity, with just a few exceptions. And yet, the biomass is easy to transform into useful products, including fuels, and they contain many other natural products that have high value. In this video Los Alamos and New Mexico State University scientists outline the opportunities and challenges of using science to turn algae into energy.

    1997-12-01

    This paper describes a USAID/USDOE sponsored program to implement renewable energy in Mexico for productive uses. The objectives are to expand markets for US and Mexican industries, and to combat global climate change - primarily greenhouse gas emissions. The focus is on off-grid applications, with an emphasis on developing the institution structure to support the development of these industries within the country. Agricultural development is an example of the type of industry approached, where photovoltaic and wind power can be used for water pumping. There are hundreds of projects under review, and this interest has put renewables as a line item in Mexico`s rural development budget. Village power projects are being considered in the form of utility partnerships.

  15. Donation transplants and tissue banking in Mexico.

    Knowledge about transplants in Mexico goes back to the Aztec period. Today the need for organ and tissue transplants in Mexico is high; the estimated number is 100,000 patients, but there are only 2 donors per million population, for corneas. The organ, tissue and cell transplantation law which was modified in 2,000, establishes that when a person dies, he will be a potential donor of organs and tissues. This new law will give hope to many patients, since it is expected to increase significantly the amount of organs and tissues for transplants. At present Mexico has 178 hospitals that are authorized to carry out organ and tissue transplants, and 53 Tissue Banks.

    The objective of this article is to report psychometric characteristics of the AUDIT, CAGE, RAPS4, and TWEAK and to compare them across three countries: Argentina, Mexico, and the United States which used a similar protocol and methodology. Probability samples of patients 18 years and older were drawn from emergency departments in Mar del Plata, Argentina (n=780), Pachuca, Mexico (n=1624) and Santa Clara, U.S. (n=1220). Concurrent validity was assessed by comparing their performance against a diagnosis of alcohol dependence (DSM-IV) obtained through the Composite International Diagnostic Interview, and for the briefer measures, also by their correlation with the AUDIT. The internal consistency of the CAGE, RAPS4, and TWEAK scores was estimated by the KR-20 formula and by Cronbach's Alpha for the AUDIT. Corrected item-total correlation and D-values were used as item discrimination measures. In Argentina and Mexico the AUDIT and the RAPS4 showed the highest validity. Reliability of all instruments was higher in the US than in Argentina or Mexico. In all three countries, reliability of the TWEAK was lowest, while the AUDIT was highest. With a few exceptions, all items showed good discrimination powers.

    Parasitic diseases are very important in Mexico because of their economic impact and adverse effects on normal growth in children. Cryptosporidiosis has been associated with acute diarrhea in immune competent and incompetent human hosts, fecal contamination of drinking water sources, and handling of animals. Due to the lack of reports on cryptosporidiosis in Mexico, we conducted a parasitologic study in children with diarrhea and other clinical symptoms. The main objectives were 1) to determine the prevalence of cryptosporidiosis in children less than one year of age in Mexico City, and 2) to correlate Cryptosporidium infection with gastrointestinal symptoms. Two hundred fecal samples from children seen at the Gabriel Mancera Familiar Medicine Unit of the Instituto Mexicano del Seguro Social were studied. Children were divided into two groups. Group A was composed of sick children with 6-8 watery diarrheic episodes every 24 hours attended at the emergency service. Group B was composed of healthy babies getting routine check ups. Only children in group A were found to be infected with intestinal protozoa (50% with Giardia lamblia, 41% with Cryptosporidium spp., and 4% with Entamoeba histolytica). The results suggested a high incidence of Cyrptosporidium infections in children in Mexico City, which make these observations useful for future studies.

    Background A preliminary biometric and ecologic database for the brine shrimp Artemia from Mexico and Chile is presented. The area abounds in small and seasonal ponds and large inland lakes, the latter mainly located in Mexico, although relatively large and isolated lakes are found in complex hydrological settings in pre-high plateau areas of Chile. This paper summarizes research efforts aimed at the localization, characterization, and evaluation of the aquaculture potential of Artemia populations in Mexico and Chile, which exhibit great habitat diversity (ponds, salterns, coastal lagoons, sea arms, coastal and inland lakes), contrasting weather conditions and different levels of isolation and human intervention. Results This study covered locations between 29° north latitude (Baja California, Mexico) to 50° south latitude (Puerto Natales, Chile). Biological characteristics considered are species name, reproductive mode, cyst diameter, chorion thickness, and nauplius length, whereas ecological data include pond size, pH, salinity, temperature, and water ionic composition. Artemia franciscana is the only species found in Mexico, it exists together with A. persimilis in Chile, though separated geographically. Ecological differences in habitat exist between both regions but also within countries, a pattern particularly clear with regard to water composition. Surprisingly, a Mexican (Cuatro Ciénegas, A. franciscana) and a Chilean location (Torres del Paine, A. persimilis) share habitat characteristics, at least for the period when data were collected. The discriminat analysis for cyst diameter and nauplius length shows that Artemia from only one location match in cyst diameter with those from San Francisco Bay (SFB) (Point Lobos), and one (Marquez) is far apart from SFB and all the others. The Chilean locations (Pampilla, Cejar, Cahuil, Llamara, Yape) share cyst diameter, but tend to differ from SFB. The remaining Mexican locations (Juchitan, Ohuira, Yavaros) are

    Bats are reservoirs for a wide range of human pathogens including Nipah, Hendra, rabies, Ebola, Marburg and severe acute respiratory syndrome coronavirus (CoV). The recent implication of a novel beta (β)-CoV as the cause of fatal respiratory disease in the Middle East emphasizes the importance of surveillance for CoVs that have potential to move from bats into the human population. In a screen of 606 bats from 42 different species in Campeche, Chiapas and Mexico City we identified 13 distinct CoVs. Nine were alpha (α)-CoVs; four were β-CoVs. Twelve were novel. Analyses of these viruses in the context of their hosts and ecological habitat indicated that host species is a strong selective driver in CoV evolution, even in allopatric populations separated by significant geographical distance; and that a single species/genus of bat can contain multiple CoVs. A β-CoV with 96.5 % amino acid identity to the β-CoV associated with human disease in the Middle East was found in a Nyctinomops laticaudatus bat, suggesting that efforts to identify the viral reservoir should include surveillance of the bat families Molossidae/Vespertilionidae, or the closely related Nycteridae/Emballonuridae. While it is important to investigate unknown viral diversity in bats, it is also important to remember that the majority of viruses they carry will not pose any clinical risk, and bats should not be stigmatized ubiquitously as significant threats to public health.

    In recent years, New Mexico has hosted television and motion picture film crews working on both famous and not-so-famous productions. Perhaps the most famous of these productions was the television hit Breaking Bad. Perhaps the least famous production, which almost certainly no one remembers, is the 1962-1963 television series Empire. Empire was an hour long western that chronicled the lives of 1960s ranchers in New Mexico. The series starred Richard Egan, Ryan O’Neal, Denver Pyle, and Charles Bronson. Guest stars included Robert Vaughn (The Man from Uncle), Inger Stevens (The Farmer’s Daughter), Robert Culp (I Spy), and Telly Savalas (Kojak).

A wide-field imaging study with interference filters has revealed 35 new Herbig-Haro objects in the Gulf of Mexico. A grism survey has identified 41 Hα emission-line stars, 30 of them new. A small cluster of partly embedded pre-main sequence stars is located around the known LkHα 185-189 group of stars, which includes the recently erupting FUor HBC 722.

    Spawning aggregations of red hind Epinephelus guttatus, tiger grouper Mycteroperca tigris and yellowfin grouper Mycteroperca venenosa were identified at two coral-reef systems: Arrecife Alacranes (emergent bank reef) and Bajos del Norte (submerged bank reef) on the continental shelf of the Yucatan Peninsula (Campeche Bank), Mexico. At both reefs, E. guttatus forms large spawning aggregations between February and March. At Bajos del Norte, M. tigris reproduces in a small, low-density aggregation in May, while M. venenosa aggregates at high densities for spawning between March and May. Multi-species use of an aggregation site by E. guttatus and M. venenosa was observed at Bajos del Norte. The identified spawning aggregations are apparently stable in location over time, and all three species were commonly observed to spawn within 1 week following the full moon. Development and survival of the larvae spawned in these aggregations are probably aided by a seasonal (spring-summer) upwelling in the north-east Campeche Bank. A permanent area closure at Bajos del Norte, currently outside any specific fisheries management area or regulations, would provide protection needed for the spawning aggregations of these three species.

    Stegomyia aegypti (= Aedes aegypti) (Diptera: Culicidae) is a species of mosquito that is currently widespread in Mexico. Historically, the mosquito has been distributed across most tropical and subtropical areas lower than 1700 m a.s.l. Currently, populations that are found at higher altitudes in regions with cold and dry climates suggest that these conditions do not limit the colonization and population growth of S. aegypti. During a survey of mosquitoes in September 2015, larvae of S. aegypti mosquitoes were found in two different localities in Mexico City, which is located at about 2250 m a.s.l. Mexico City is the most populous city in Mexico and has inefficient drainage and water supply systems. These factors may result in the provision of numerous larval breeding sites. Mosquito monitoring and surveillance are now priorities for the city.

    Tuberculosis (TB) is one of the oldest human diseases that still affects large population groups. According to the World Health Organization (WHO), there were approximately 9.4 million new cases worldwide in the year 2010. In Mexico, there were 18,848 new cases of TB of all clinical variants in 2010. The identification of clusters in space-time is of great interest in epidemiological studies. The objective of this research was to identify the spatial and temporal distribution of TB during the period 2006–2010 in the State of Mexico, using geographic information system (GIS) and SCAN statistics program. Nine significant clusters (P < 0.05) were identified using spatial and space-time analysis. The conclusion is that TB in the State of Mexico is not randomly distributed but is concentrated in areas close to Mexico City. PMID:22919337

    Tropical coastal wetlands, including rainforests and mangrove ecosystems play an increasingly important ecological and economic role in the tropical coastal area of the State of Veracruz /Mexico. However, soil processes in these environments, especially C-turnover rates are largely unknown until today. Therefore, we investigated CO2 and CH4 emissions together with gains and losses of organic C in the soils of two different coastal ecosystems in the "Natural Protected Area Cienaga del Fuerte (NPACF)" near Tecolutla, in the State of Veracruz. The research areas were an artificially introduced grassland (IG) and a wetland rainforest (WRF). The gas emissions from the soil surfaces were measured by a static chamber array, the soil organic C was analysed in soil profiles distributed in the two areas, humic substances were characterized and C budget was calculated. The soils in both areas acted as carbon sinks, but the soils of the WRF sequestered more C than those of the IG, which showed a higher gas emission rate and produced more dissolved organic carbon. The gas emission measurements during the dry and the rainy seasons allowed for estimating the possible influence of global warming on gas fluxes from the soils of the two different ecological systems, which show in the WRF a quite complex spatial emission pattern during the rainy season in contrast to a more continuous emission pattern in the IG plots

  18. Illegal sales of cigarettes to minors--Mexico City, Mexico, 1997.

    PubMed

    1997-05-23

    Because of the increasing prevalence of tobacco use among youth in the United States and Mexico, in 1996 the United States-Mexico Binational Commission (US-MBC) Health Working Group identified prevention of tobacco use, with an emphasis on adolescents, as one of its four priority health concerns. From 1970 to 1990, annual death rates for the leading causes of smoking-related deaths in Mexico nearly tripled and, in 1992, an estimated 10,253 persons in Mexico died as a result of smoking-related diseases, 9% of all deaths that year. In addition, from 1988 to 1993, the prevalence of current smoking among minors aged 12-17 years increased from 6.6% to 9.6%, respectively (in Mexico City, the 1993 prevalence was 12.8%), and in 1993, 72% of adult smokers in Mexico reported becoming regular smokers before age 18 years. Although since 1984 the General Health Law of Mexico has prohibited the sale of tobacco products to minors aged < 18 years, compliance with this law has not been assessed. As part of the Mexican national program to reduce the prevalence of cigarette smoking among children and adolescents and in support of the goals of the US-MBC, during 1997 the General Directorate of Epidemiology (GDE) in the Secretariat of Health (SOH) conducted a survey of tobacco outlets in Mexico City to assess the percentage of retailers willing to sell cigarettes to minors. This report summarizes the results of the survey, which indicate that virtually no surveyed retailers asked minors attempting to purchase cigarettes about their age and that most retailers sold cigarettes to minors.

    2011-12-01

    The Servicio Sismológico Nacional (SSN) is Mexico's official organism in charge of the observation of seismicity in the country. Operated by the Universidad Nacional Autonoma de Mexico, it counts with 32 broadband stations deployed throughout the country. The coverage includes most of the geologic provinces of the territory, which vary widely in their geologic characteristics. The availability of records from teleseisms at those stations makes feasible to obtain sound and homogeneous estimates of the structure of the crust in the Mexican territory through the analysis of receiver functions (RF). In this work we present the results of the analysis of RF obtained from events registered from 1998 to 2009 in the 32 stations of the SSN. The RF technique, which uses converted phases at major velocity discontinuities, is a well established technique to infer the velocity contrasts and thickness of the underlying crust. Using this method we were able to infer the depth of the Moho, a major intracrustal discontinuity and in some cases the depth to the base of the subducting plate. We present maps of crustal thickness in Mexico, which varies between about 29 km in the Yucatan peninsula to more than 40 km in central Mexico. Poisson's coefficient varies between 0.19 and 0.30. The position of the descending slab shows a large variation in the subduction angle (from about 6° in the SE margin of the Pacific coast to about 60° in the NW ) as has been found from other techniques.

    We use data from three rounds of the Mexican Family Life Survey to examine whether migrants in the United States returning to Mexico in the period 2005–2012 have worse health than those remaining in the United States. Despite extensive interest by demographers in health-related selection, this has been a neglected area of study in the literature on U.S.-Mexico migration, and the few results to date have been contradictory and inconclusive. Using five self-reported health variables collected while migrants resided in the United States and subsequent migration history, we find direct evidence of higher probabilities of return migration for Mexican migrants in poor health as well as lower probabilities of return for migrants with improving health. These findings are robust to the inclusion of potential confounders reflecting the migrants’ demographic characteristics, economic situation, family ties, and origin and destination characteristics. We anticipate that in the coming decade, health may become an even more salient issue in migrants’ decisions about returning to Mexico, given the recent expansion in access to health insurance in Mexico.

    2015-01-01

    Canine parvovirus (CPV) is one of the most common infectious agents related to high morbidity rates in dogs. In addition, the virus is associated with severe gastroenteritis, diarrhea, and vomiting, resulting in high death rates, especially in puppies and nonvaccinated dogs. To date, there are 3 variants of the virus (CPV-2a, CPV-2b, and CPV-2c) circulating worldwide. In Mexico, reports describing the viral variants circulating in dog populations are lacking. In response to this deficiency, a total of 41 fecal samples of suspected dogs were collected from October 2013 through April 2014 in the Veterinary Hospital of the University of Guadalajara in western Mexico. From these, 24 samples resulted positive by polymerase chain reaction, and the viral variant was determined by restriction fragment length polymorphism. Five positive diagnosed samples were selected for partial sequencing of the vp2 gene and codon analysis. The results demonstrated that the current dominant viral variant in Mexico is CPV-2c. The current study describes the genotyping of CPV strains, providing valuable evidence of the dominant frequency of this virus in a dog population from western Mexico.

    New Mexico, a state of brown plains and sand deserts, is nicknamed "The Land of Enchantment." One reason is that the very starkness of the land adds to its enchantment. Another reason is that the rich history of the state has resulted in a landscape filled with remnants of the Pueblo people, Spanish colonizers, and Mexican settlers.

    Human monocytic ehrlichiosis is a febrile illness caused by Ehrlichia chaffeensis, an intracellular bacterium transmitted by ticks. In Mexico, a case of E. chaffeensis infection in an immunocompetent 31-year-old woman without recognized tick bite was fatal. This diagnosis should be considered for patients with fever, leukopenia, thrombocytopenia, and elevated liver enzyme levels.

  1. Air Pollution in the Mexico Megacity

    NASA Astrophysics Data System (ADS)

    Ruiz-Suarez, L. G.

    2007-05-01

    Mexico City is a megacity whose metropolitan area includes the country federal district, 18 municipalities of the State of Mexico. In year 1992, only 16 municipalities of the State of Mexico were part of MCMA. In year 1940 the Mexico City population was 1.78 millions in an area of 118 km2, in year 2000 the population was 17.9 millions in an area of 1,500 km2. Population has grown a ten fold whereas population density has dropped 20%. Total number of private cars has grown from 2,341,731 in year 1998 to 2,967,893 in year 2004. Nowadays, people and goods travel longer at lower speed to reach school, work and selling points. In addition highly efficient public transport lost a significant share of transport demand from 19.1 in 1986 to 14.3 in 1998. Air pollution is a public concern since early eighties last century; systematic public efforts have been carried out since late eighties. Energy consumption has steadily increased in the MCMA whereas emissions have also decreased. From year 2000 to 2004, the private cars fleet increased 17% whereas CO, NOx and COV emissions decreased between 20-30%. Average concentrations of criteria pollutants have decreased The number of days that the one-hour national standard for bad air quality was exceeded in year 1990 was 160. In year 2005 was 70. Research efforts and public policies on air pollution have been focused on public health. We are now better able to estimate the cost in human lives due to air pollution, or the cost in labor lost due to illness. Little if none at all work has been carried out to look at the effect of air pollution on private and public property or onto the cultural heritage. Few reports have can be found on the impact of air pollution in rural areas, including forest and crops, around the mega city. Mexico City is in the south end of a Valley with mountain ranges higher than 1000 m above the average city altitude. In spite the heavy loss of forested areas to the city, the mountains still retain large

Objetivo: Determinar la prevalencia de asma y sus síntomas en la ciudad de Cuernavaca, Morelos, México. Métodos: Estudio descriptivo de prevalencia en escuelas oficiales de la ciudad de Cuernavaca, Morelos, de nivel preescolar, primaria y secundaria, mediante el “Cuestionario diagnóstico de asma para estudios epidemiológicos”. Resultados: Se obtuvieron 7947 encuestas en escolares de 3 a 15 años, encontrándose una prevalencia de asma de 11.9%, 49% en niños y 51 % en niñas. En cuanto a los síntomas de asma, la mayor prevalencia la obtuvo la tos que aumenta con el frío (63%), sin embargo, en los pacientes con asma este síntoma solo se presentó en 17%; la opresión torácica tuvo la prevalencia más baja entre los síntomas (10%), sin embargo, en pacientes con asma fue de 49%. Conclusiones: Con el cuestionario diagnóstico de asma para estudios epidemiológicos se encontró una prevalencia promedio de asma de 11.9% en preescolares, escolares y alumnos de secundaria, discretamente inferior a la diagnosticada en otras ciudades del centro de México. La prevalencia de los síntomas de asma resultó más elevada que la del diagnóstico de asma.

    Antecedentes: debido a la alta prevalencia de enfermedades alérgicas en México causadas por exposición a polen, en las últimas décadas se han hecho estudios de plantas y pólenes atmosféricos en varias regiones. En la ciudad de Toluca se hicieron dos muestreos polínicos, mediante metodología gravimétrica, por lo que es necesario hacer un estudio con metodología volumétrica estandarizada para obtener resultados actualizados y confiables de una región con cambios ambientales considerables en los últimos años. Objetivo: determinar los diferentes tipos polínicos, las variaciones estacionales y su comportamiento en las cuatro estaciones del año. Material y método: estudio descriptivo de la identificación de pólenes, mediante el método de succión y captura de partículas con el muestreador volumétrico tipo Hirst (Burkard), efectuado en la ciudad de Toluca, México, del 1 de octubre de 2004 al 30 de septiembre de 2005. Resultados: se identificaron 29 diferentes tipos polínicos, con un conteo total de 13,542 granos de polen. Durante el invierno se encontró la mayor cantidad de pólenes. Los meses con mayor y menor cantidad de pólenes fueron enero y agosto, respectivamente. Predominaron los árboles, principalmente de la familia Cupressaceae (44%) y polen de Pinaceae (13.8%); estos dos grupos polínicos estuvieron presentes durante todo el año. Conclusiones: identificamos una mayor cantidad de pólenes de árboles durante el invierno, principalmente de la familia Cupressaceae, lo que se relaciona estrechamente con la cantidad de árboles sembrados de esta especie en la ciudad.

  8. Palaeoenvironmental Fluctuations Identified by Diatoms, Ostracode, Geochemistry and Sedimentary Facies from a Tropical Crater Lake on Western Mexico

    NASA Astrophysics Data System (ADS)

    Caballero, M.; Rodriguez, A.; Vazquez, G.; Ortega, B.; Lozano, M.; Vilaclara, G.

    2007-05-01

    A ca. 2500 cal. yr record from Santa Maria del Oro (SMO) was studied for its diatoms, ostracodes, magnetic mineralogy, geochemestry, organic matter and carbonate content to document climatic and limnological trends over western Mexico, a site sensitive to the intensity of monsoon circulation and to any latitudinal shifts of the high pressure subtropical cells as it is currently located on a transition zone between the temperate climates of central Mexico highlands and the arid climates of northern Mexico. The sediment sequence (8.8 m) has a chronology is based on 7 AMS dates. The sequence shows an irregular sequence of four distinctive facies (laminations). Data derived from the analysis of easch facies and of modern sediments supports the interpretation that sand and peaty layers are mostly alloctonous in origin while the silty layers (ochre, brown and greenish silt) are mostly autigenic. Ochre layers represent times of anoxic bottom lake conditions favoured by a warmer environment. Long term trends are also present along the sequence. Warm and relatively humid conditions change to a drier climate by ca. AD 600, with the driest and warmest stage recorded at AD 990. This dry period is consistent with records of arid phases at other sites in Mesoamerica. From AD 990 to AD 1260 there is evidence of a sudden transition to warm-humid conditions and dilution of lake water coeval with the Medieval Warm Period. From AD 1260 to AD 1480 climatic conditions were unstable and afterwards the onset of drier climates is recorded until the present. Due to its geographical position, moisture availability fluctuations are responding to atmospheric circulation changes such as latitudinal shifts of the Intertropical Convergence Zone and Subtropical High- Pressure Cells resulting in the strengthening or weakening of the summer monsoon, which is the main moisture source for western Mexico. This sequence records environmental and climatic variability for western central Mexico and

    We used 15 short tandem repeat (STR) loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818, and FGA) to genetically characterize 361 individuals from 11 indigenous populations (Amuzgo, Chinanteco, Chontal, Huave, Mazateco, Mixe, Mixteco, Triqui, Zapoteco del Istmo, Zapoteco del Valle, and Zoque) from Oaxaca, Mexico. We also used previously published data from other Mexican peoples (Maya, Chol, Tepehua, Otomí, and Mestizos from northern and central Mexico) to delineate genetic relations, for a total of 541 individuals. Average heterozygosity (H) was lower in most populations from Oaxaca (range 0.687 in Zoque to 0.756 in Chontal) than values observed in Mestizo populations from Mexico (0.758 and 0.793 in central and northern Mestizo, respectively) but higher than values observed in other Amerindian populations from South America; the same relation was true for the number of alleles (n(a) ). We tested (using the software Structure) whether major geographic or linguistic barriers to gene flow existed among the populations of Oaxaca and found that the populations appeared to constitute one or two genetic groups, suggesting that neither geographic location nor linguistics had an effect on the genetic structure of these culturally and linguistically highly diverse indigenous peoples. Moreover, we found a low but statistically significant between-population differentiation. In addition, the genetic structure of Oaxacan populations did not fit an isolation-by-distance model. Finally, using AMOVA and a Bayesian clustering approach, we did not detect significant geographic or linguistic barriers to gene flow within Oaxaca. These results suggest that the indigenous communities of Oaxaca, although culturally isolated, can be genetically defined as a large, nearly panmictic population in which migration could be a more important population mechanism than genetic drift. Finally, compared with outgroups in Mexico (both

    Streamflow and water quality vary spatially and temporally in the Rio Grande from Del Norte, Colorado, to El Paso, Texas. The variations in streamflow and in concentrations of selected waterquality constituents?dissolved solids, dissolved nitrite plus nitrate as nitrogen, total phosphorus, and suspended sediment?are described in this report. A multivariate linear regression model, ESTIMATOR2000, was used to estimate loads for selected constituents. Streamflow decreases in the downstream direction throughout most of the basin because outflows (due to agricultural use, leakage to ground water, and evapotranspiration) are greater than inflows. Streamflow increases between Rio Grande above the mouth of Trinchera Creek, near Lasauses, Colorado, to Rio Grande at Otowi Bridge, near San Ildefonso, New Mexico, because ground-water and tributary inflow are greater than outflow. Concentrations of dissolved solids, dissolved nitrite plus nitrate, total phosphorus, and suspended sediment generally increase in the downstream direction. Concentrations of dissolved solids, dissolved nitrite plus nitrate, and total phosphorus decrease between Rio Grande above the mouth of Trinchera Creek, near Lasauses, Colorado, and Rio Grande at Otowi Bridge, near San Ildefonso, New Mexico, because of dilution by tributary inflow. Concentrations of dissolved nitrite plus nitrate, total phosphorus, and suspended sediment decrease between Rio Grande Floodway at San Marcial, New Mexico, and Rio Grande below Leasburg Dam, near Leasburg, New Mexico, because of reservoir effects (nutrient uptake and settling of sediment). Several instances of decreasing streamflow and increasing loads indicate the presence of inflows with large constituent concentrations (relative to those of the Rio Grande immediately upstream from that inflow); this occurs (1) between Rio Grande near Del Norte, Colorado, and Rio Grande above the mouth of Trinchera Creek, near Lasauses, Colorado, for dissolved solids, (2) between Rio

    For more than 10 years we try to follow the steps of the Southern California Integrated GPS Network (SCIGN) and the Plate Boundary Observatory (PBO) in USA, this gives us the opportunity to be in position to contribute to develop a modern GPS Network in Mexico. During 1998 and 2001, three stations were deployed in Northwest Mexico in concert with the development of SCIGN: SPMX in north central Baja California state at the National Astronomical Observatory, UNAM in the Sierra San Pedro Martir; CORX in Isla Coronados Sur, offshore San Diego, Ca./Tijuana, Mexico and GUAX in Guadalupe island 150 miles offshore Baja California peninsula, which provide a unique site on the Pacific plate in the Northamerica/Pacific boundary zone in Las Californias. The former IGS station in CICESE, Ensenada, CICE installed in 1995, was replaced by CIC1 in 1999. In 2004 and 2005 with partial support from SCIGN and UNAVCO to University of Arizona a volunteer team from UNAVCO, Caltech, U.S. Geological Survey, Universidad de la Sierra at Moctezuma Sonora and CICESE built two new shallow-braced GPS sites in northwest Mexico. The first site USMX is located at east-central Sonora and the second YESX is located high in the Sierra Madre Occidental at Yecora near the southern border of Sonora and Chihuahua. All data is openly available at SOPAC and/or UNAVCO. The existing information has been valuable to resolve the "total" plate motion between the Pacific plate (GUAX) and the Northamerica plate (USMX and YESX) in the north- central Gulf of California. Since the last year we have the capability of GPS data processing using GAMIT/GLOBK, and after gain some practice with survey mode data processing we can convert us in a GPS processing center in Mexico. Currently only 2 sites are operational: CIC1 and USMX. With new energy we are ready to contribute to the establishment of a modern GPS network in Mexico for science, hazard monitoring and infrastructure.

    El estudio experimental de las interacciones de átomos Rydberg altamente excitados con campos eléctricos ha experimentado un creciente interés durante las dos últimas décadas debido, en gran medida, al desarrollo de nuevas técnicas para crear y estudiar átomos Rydberg en el laboratorio. Acompañando a estas nuevas técnicas experimentales, es necesario el desarrollo de modelos teóricos que nos permitan contrastar sus medidas y conocer mejor los fundamentos de los mismos. Desde el punto de vista teórico el conocimiento del desdoblamiento de los niveles energéticos de un átomo en función de la magnitud del campo eléctrico aplicado (lo que se conoce como mapa Stark) es el mejor punto de partida para la descripción del sistema y un prerrequisito fundamental para el cálculo de distintas propiedades atómicas en presencia del campo eléctrico tales como intensidades de transición, umbrales de ionización de campo eléctrico, tiempos de vida, posición y anchura de cruces evitados, etc. En este trabajo presentamos la adaptación del método de orbitales de defecto cuántico [1,2,3] al tratamiento del efecto Stark (SQDO) [4] y su aplicación al cálculo de los desdoblamientos energéticos y fuerzas de oscilador de estados Rydberg en los átomos de Li, Na y K. El propósito de este estudio es, por un lado, desarrollar métodos fiables para la determinación de propiedades atómicas en presencia de campos eléctricos y, por otro, mostrar la fiabilidad de las funciones de onda QDO en la descripción del efecto Stark en sistemas atómicos.

    Background Frequent recurrent BRCA1 and BRCA2 gene (BRCA) mutations among Hispanics, including a large rearrangement Mexican founder mutation (BRCA1 ex9-12del), suggest that an ancestry-informed BRCA-testing strategy could reduce disparities and promote cancer prevention by enabling economical screening for hereditary breast and ovarian cancer in Mexico. Methods In a multistage approach, 188 cancer cases unselected for family cancer history (92 ovarian cancer and 96 breast cancer) were screened for BRCA mutations using a Hispanic mutation panel (HISPANEL®) of 115 recurrent mutations in a multiplex assay (114 on a mass spectroscopy platform, and a PCR assay for the BRCA1 ex9-12del mutation), followed by sequencing of all BRCA exons and adjacent intronic regions, and BRCA1 multiplex ligation-dependent probe amplification assay (MLPA) for HISPANEL negative cases. BRCA mutation prevalence was calculated and correlated with histology and tumor receptor status, and HISPANEL sensitivity was estimated. Results BRCA mutations were detected in 28% (26/92) of ovarian cancer cases and 15% (14/96) of breast cancer cases overall and 27% (9/33) of triple negative breast cancer. Most breast cancer cases were diagnosed with locally advanced disease. The Mexican founder mutation (BRCA1 ex9-12del) accounted for 35% of the BRCA-associated ovarian cancer cases and 29% of the BRCA-associated breast cancer cases. At 2% of the sequencing and MLPA cost, the HISPANEL detected 68% of all BRCA mutations. Conclusion In this study, we found a remarkably high prevalence of BRCA mutations among ovarian and breast cases not selected for family history, and BRCA1 ex9-12del explained one third of the total. The remarkable frequency of BRCA1 ex9-12del in Mexico City supports a nearby origin of this Mexican founder mutation and may constitute a regional public health problem. The HISPANEL presents a translational opportunity for cost-effective genetic testing to enable breast and ovarian cancer

    Delgado, Isabel C.

    Los modelos de eensenanza y aprendizaje constructivistas conceptualizan el aprendizaje como un proceso activo. El modelo de Aprendizaje Basado en Proyectos (ABPr) se distingue por una serie de componentes, entre los cuales se destaca el aspecto colaborativo y cooperativo como un reto al momento de su implantacion. Son pocas las investigaciones que se concentran en este aspecto del modelo. En este estudio, se analizaron las diversas interacciones que surgen durante la implantacion de una unidad curricular sobre el tema de Geologia de Puerto Rico, la cual se diseno con el modelo ABPr cuyo enfoque es orientacion a proyectos. Particularmente, se examinaron las interacciones sociales que surgen entre los pares y entre pares y docente durante el proceso de planificacion y desarrollo de los productos finales, al igual que las interacciones entre los estudiantes y el material didactico en estas etapas del modelo. La investigacion es de tipo cualitativo e incorpora como diseno el estudio de caso. Las diversas interacciones constituyen la unidad de analisis. En el estudio participaron 19 estudiantes de 9no grado, a quienes se organizaron en 5 grupos colaborativos por temas de interes (Pangea, Placas tectonicas, Volcanes, Tsunamis y Terremotos). Las tecnicas que se utilizaron para recopilar los datos fueron: observaciones participativas, grupos focales y analisis de documentos (cuadernos reflexivos y respuestas de los estudiantes a la pregunta central del proyecto). Para el analisis de los datos se aplico la teoria de actividad (CHAT) que concentra la unidad de analisis en la actividad humana en un contexto particular.

    This report examines selected factor affecting Mexico's future petroleum policies, and then assesses various implications of Mexico's petroleum for US interests and policies. After a brief introduction, the report is divided into three sections. The first offers a detailed analysis of Mexico's petroleum resources and production possibilities. The second considers petroleum as a symbolic issue of profound significance for Mexican nationalism. The final section provides an assessment of these and other factors for US interests, objectives, and policy options during the 1980s.

    The objective of this study was to estimate the extent to which parental psychopathology may confer increased risk of suicide ideation and attempts among their offspring in Mexico. Data from a representative sample of 5,782 respondents participating in the Mexican National Comorbidity Survey (2001-2002) to examine the unique associations between parental psychopathology and offspring suicidality were used. Parental disorders (major depression, panic disorder, generalized anxiety disorder, substance dependence, and antisocial personality disorder) were comorbid and after controlling for comorbidity and number of disorders only parental panic and antisocial personality disorder remained associated with ideation and attempts in the total sample. Those with more parental disorders were at increased risk of ideation and attempt, as well as increased risk to transition from suicide ideation to an attempt. These findings may help inform clinical and public health efforts aimed at suicide prevention in Mexico and other developing countries.

    Type 2 diabetes is the main health problem in Mexico. The large and growing number of cases and the remarkable economic impact of the disease support this statement. The condition is expressed at an earlier age and at a lower body mass index in Mexican mestizos compared with the age and body mass index reported in Caucasians. In addition, Mexican mestizos have an increased susceptibility to developing diabetic nephropathy. The Mexican health system needs major adjustments in order to prevent and treat type 2 diabetes. Treatment is not currently based on the needs and expectations of the patient. As a result, it is insufficient, belated, and costly. Close to 20% of the preventable deaths in Mexico are caused by diabetes and related metabolic diseases. Even a small decrease in this rate could result in substantial savings for the Mexican healthcare system.

  3. Determinants of occupational disease incidence in Mexico.

    2005-01-01

    Most occupational health researchers have studied individual determinants, tending to forget those causes that are universally present. To explore some determinants of occupational disease incidence in Mexico, the authors carried out an ecological study with data from 32 Mexican states. Using ordinary least squares regression, they explored associations between occupational disease incidence and the Gini coefficient, the percentage of small and median enterprises, and migration. Income inequality and the combined percentage of small and median enterprises were negatively associated with the incidence of occupational disease. In Mexico, the "population strategy" of the prevention of occupational disease suggests that big enterprises' contexts are related to a higher occurrence of occupational diseases. Further studies using multilevel approaches are needed to establish whether these occupational diseases are related to exposures present in big or in small and median enterprises.

    In national standing, the Land of Enchantment dropped in 1992 from 10th to 13th in total mineral value. Dropping 12% from 1991, New Mexico's 1992 nonfuel mineral production was valued at $871 million, 2.72% of U.S. total value. New Mexico continued to lead the Nation in potash and perlite output. It ranked second in the country in production of mica and pumice, third in U.S. copper production, and fourth in natural gas production. Values of copper and potash continued to lead other State mineral commodities by about a factor of 10. Relative to 1991 State performance, value of portland and masonry cement, common clay, crude gypsum, mica, perlite, potash, pumice, sand and gravel, crushed stone, and zeolites increased in 1992.

    DNA barcoding has become an important current scientific trend to the understanding of the world biodiversity. In the case of mega-diverse hot spots like Mexico, this technique represents an important tool for taxonomists, allowing them to concentrate in highlighted species by the barcodes instead of analyzing entire sets of specimens. This tendency resulted in the creation of a national network named Mexican Barcode of Life (MEXBOL) which main goals are to train students, and to promote the interaction and collective work among researchers interested in this topic. As a result, the number of records in the Barcode of Life Database (BOLD) for some groups, such as the Mammalia, Actinopterygii, Polychaeta, Branchiopoda, Ostracoda, Maxillopoda, Nematoda, Pinophyta, Ascomycota and Basidiomycota place Mexico among the top ten countries in the generation of these data. This special number presents only few of the many interesting findings in this region of the world, after the use of this technique and its integration with other methodologies.

    The Gulf of Mexico is a small ocean basin between the US and Mexico that opened up soon after the breakup of Pangea. Although the area has been heavily surveyed with seismic reflection profiles, the deep structure of the region is poorly understood because of lack of penetration beneath the thick sediments and salt. We present the results of the GUMBO (GUlf of Mexico Basin Opening) project that constrains seismic velocities and thicknesses of the sediments and crust from the continental shelf to deep ocean basin in the northern Gulf of Mexico. Data were acquired in 2010 along four profiles 300-500 km in length, using the industry vessel R/V Iron Cat and ocean bottom seismometers at 10-12 km spacing. Plate tectonic models for the Gulf of Mexico region have rifting initiating in the Late Triassic or Early Jurassic, with seafloor spreading beginning ~166-154 Ma in the western Gulf, propagating to the eastern Gulf, and ending ~154-135 Ma. Many models include transform motion along the Florida margin during initiation of continental rifting. We observe a strong change in rifting style from west to east across the ocean basin. Our western profile, offshore Texas, images highly heterogeneous crust with sediment velocities directly overlying Moho in some locations. These observations are consistent with either sedimentary basins within rifted continental crust or ultra-slow-spreading oceanic crust. The profile offshore Lousiana images thicker, faster, and more homogeneous crust. This could suggest an eastward increase in magmatic output during rifting. The eastern profiles offshore Alabama and Florida image the ocean-continent boundary and extensive regions of oceanic crust. The thickness of crystalline crust from the continental shelf to the deep basin decreases from ~25 km to 6-7 km over a horizontal distance of 150 km in the eastern Gulf of Mexico. The profile offshore Alabama, near a region where syn-rift volcanism has been interpreted on seismic reflection data, has

    Application of Geographical Information Systems (GIS) in Mexico for the solution of territorial-based problems has been widely extended in the last decade. However, teaching and learning have been mainly based on short training courses or workshops focused on software knowledge acquiring, but without the basic background of geographical sciences that allow the understanding of fundamentals principles related to geographical information management, theory, methods of analysis and modeling, as well as the study of interactions between the different processes across the land surface. In spite of the explosive growth of the GIS use, the teaching of fundamental principles still is limited to formal courses taught in universities. The goal of this study is to analyze the role of GIS technology as generator of territorial knowledge, its evolution and use by companies, as well as its presence in curricular plans of study in the different engineering programs in Mexico.

    This article covers the report on Supply of Medical Equipment in Mexico, presented during the Second National Congress of Public Health. The results are part of an investigation that dealt with the general conditions that currently prevail in the production and distribution of medical equipment. The information was obtained by means of a survey applied to 208 companies that comprised the sample study. The facts indicate that of the companies that correspond to this industrial sector in Mexico, 3.8 per cent are manufacturers, 69.7 per cent distributors, 19.2 per cent manufacturer-distributors, and the remaining 7.2 per cent correspond to corrective and preventive maintenance. Also, these companies pose serious problems of external dependence with regard to production costs and the commercialization of products. Furthermore, it became evident that there is a substantial need for financial support to optimally satisfy the demands of various institutions in the country's health sector.

This photograph was taken on a seep down the coast to document the fault patterns of southern California and northwest Mexico. The specific reason for the picture was to see of the Agua Blanca Fault in Baja California extends to the east toward the Gulf of California. No such extension was found. The fault appeard to disappear into an area of sand and heavily eroded material that obscured any feature that might be present deeper. This area of sand and loose material is the light-colored area in the center of Baja at the extreme north part of the photograph.

    We examine the extent to which social networks among indigenous peoples in Mexico have a significant effect on a variety of human capital investment and economic activities, such as school attendance and work among teenage boys and girls, and migration, welfare participation, employment status, occupation, and sector of employment among adult males and females. Using data from the 10 percent population sample of the 2000 Population and Housing Census of Mexico and the empirical strategy that Bertrand, Luttmer, and Mullainathan (2000) propose, which allows us to take into account the role of municipality and language group fixed effects, we confirm empirically that social network effects play an important role in the economic decisions of indigenous people, especially in rural areas. Our analysis also provides evidence that better access to basic services such as water and electricity increases the size and strength of network effects in rural areas.

    The authors examined relationships between the wealth of older adults and their early-life decisions regarding investment in human capital, family formation, and work activities in Mexico, using the 2001 Mexican Health and Aging Study. The authors examined correlates of accumulated financial wealth by gender and across three age cohorts: 50 to 59, 60 to 69, and 70 years or older. The authors outline the changing context these cohorts experienced during their lifetimes; describe patterns of net financial worth by main covariates across groups defined by age, sex, and marital status; and present the results of multivariate models of net worth. Simulations were conducted to illustrate patterns of net worth associated with alternative scenarios depicting differing representative combinations of life-course characteristics by age cohort. The findings suggest that old-age financial wealth in Mexico is more closely associated with family formation and human capital decisions than with employment decisions over the lifetime.

    We report the results of a study conducted during 1990–2006 with 89 cases of American visceral leishmaniasis in Chiapas State in southeastern Mexico and a seroprevalence study performed with 726 persons and 224 dogs that lived near cases of American visceral leishmaniasis. Clinical aspects, epidemiologic profiles, and risk factors are described. Most cases were in children ≤ 5 years of age, the prevalence of seropositive persons was 77%. The main risk factors associated with this disease were having 1–3 rooms in a house compared with ≥ 4 rooms, having a roof that was not made of cement, and having domestic animals. In contrast, only 19% of dogs were seropositive, suggesting that this species is not important in the transmission cycle of Leishmania. These data indicate that active transmission is taking place in the central valley of Chiapas State, Mexico, in communities located < 1,000 meters above sea level near the Grijalva River.

  17. Age at menopause in Puebla, Mexico.

    Sievert, Lynnette Leidy; Hautaniemi, Susan I

    2003-04-01

    Comparisons of age at menopause are made difficult by the different methodologies applied across populations. This study extended an opportunity to apply different methodologies to the same data to draw some preliminary conclusions about age at menopause in Puebla, Mexico. Among 755 women aged 28 to 70 interviewed in the capital city of Puebla, Mexico, 447 (59.6%) were naturally or surgically postmenopausal. Mean recalled age at natural menopause in Puebla (46.7 years) appears to be similar to mean recalled age at menopause in Mexico City (46.5 years), suggesting that age at menopause is similar in urban Mexican populations. However, median age at menopause computed by probit analysis was later in the city of Puebla (49.6 years) compared to the median age computed by the same method in the capital city of León, Guanajuato, Mexico (48.2 years). Median age at menopause computed by Kaplan-Meier survival analysis suggests that age at menopause in Puebla (50.0 years) is older still, and close to that of the United States (51.1 years). The differences in median ages at menopause in Puebla are solely due to methodological choices and highlight the difficulty inherent in making inferences across studies of age at menopause between biological and/or cultural groups. Factors associated with age at menopause offer another avenue for comparing and understanding variation in this basic biological process. In Puebla, smoking, low levels of education, and nulliparity are associated with an earlier age at menopause.

    Evidence of a recent flash flood can be seen in the form of light brown sediment that flowed down gullies and mountain sides forming ponds of debris over agricultural areas in the broad valley near the town of Parras (26.5N, 102.5W). This part of Mexico has extensive vineyards, orchards and both dry land and irrigated agriculture. Based on the photo, it appears that flash flood waters damaged some 300 square miles of property in this area alone.

    This study presents an inventory of 139 nanotechnology companies in Mexico, identifying their geographic distribution, economic sector classification, and position in the nanotechnology value chain. We find that the principal economic sector of nanotechnology-engaged firms involves the manufacture of chemical products, which largely serve as means of production (primary or intermediate materials; instruments and equipment) for industrial processes. The methodology used in this analysis could be replicated in other countries without major modifications.

  11. Degeneration and the origins of Mexico's war on drugs.

    PubMed

    Campos, Isaac

    2010-01-01

    In the early twentieth century, the concept of “degeneration” helped to turn “drugs” into a problem of national importance in Mexico. By invoking this concept, Mexico's sanitary authorities secured provisions in the Constitution of 1917 which specifically authorized a newly constituted Department of Public Sanitation to lead a nation-wide campaign against drug abuse. That Department then inaugurated Mexico's modern war on drugs when, in 1920, it declared a law governing the import and distribution of the opiates, cocaine, and marijuana nationwide. This essay examines the idea of degeneration and how it came to play this crucial role in the foundation of Mexico's modern war on drugs.

    Maravilla, Dolores

    The goal of this work is to investigate what are the climate change effects at the Eastern region of Mexico. A spectral analysis of minimum extreme temperature (MET) series of 5 locations is done using the Wavelet Method covering a period of 72 years, they correspond to Atzalan, Campeche, Jalapa, Merida and Progreso meteorological stations that are located at the Eastern Mexico. The spectral analysis has been organized by seasons: spring, summer, autumn and winter for each MET series. The seasonal data have been spectrally compared with the AMO (Atlantic Multi-decadal Oscillation), the sunspots and the cosmic rays series in order to look for some periodicities related to both atmospheric and solar activity on Mexican territory. According to the results, several important periodicities related to solar activity and terrestrial atmospheric phenomena appear in the seasonal spectral analysis as is the case of the 3.2, 7.2 and 11 yrs signals. The periodicity around 3.2 yrs could be related to storm sudden commencements (SSĆs) and La Nĩa, the periodicity at 7.2 yrs possibly has a relation with n the sunspots cycle, the magnetic flux emergence and El Nĩo, meanwhile the periodicity around n at 11 yrs, as we know, is associated with the solar cycle. We suggest that the climate in Mexico could be modulated by the influence of solar activity in combination with some atmospheric terrestrial phenomena.

    Many countries, including Mexico, are facing a largely unrecognized epidemic of low-level lead poisoning. Mexico is the sixth largest lead-producing country in the world, and 40% of its production is used locally in different industrial processes that cause lead contamination of the environment. The major sources and pathways of lead exposure among the Mexican population are gasoline emissions, lead-glazed ceramics, leaded paint, and lead in canned foods and beverages. In this paper we present evidence for the presence of lead in different environmental media and its impact on blood lead levels of the Mexican population. Although during the last few years important measures have been implemented to decrease lead exposure, our findings suggest that lead poisoning is still an important problem in Mexico. There is an urgent need for regulatory policies that implement stricter control to protect the Mexican population. There is also a need to develop adequate programs to reduce the lead burden and the associated health effects in the population that has been chronically exposed. Images Figure 1. PMID:7523102

    Limited serosurveillance studies suggested that orthopoxviruses (OPXV) are widespread in the US (e.g., Raccoonpox virus, Skunkpox virus, Volepox virus) and Brazil (Vaccinia virus); however, their animal reservoir(s) remain unconfirmed. Mexican mammal diversity includes several species related to those in which evidence for OPXV infections has been found (Oryzomys, Peromyscus, Microtus, and Procyonidae). The presence of these groups of mammals in Mexico and the evidence of their possible involvement in the maintenance of OPXV in nature suggest the same or similar OPXV are circulating in Mexico. We tested 201 sera from 129 procyonids via modified enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) to estimate OPXV antibody prevalence in these animals. We detected a prevalence of 16.67% in Nasua narica (white-nosed coati), 35% in Procyon lotor (raccoon), and 30.4% in Bassariscus astutus (ring-tailed cat) when tested by either ELISA or WB. Western blot results presented protein bands consistent with the size of some OPXV immunodominant bands (14, 18, 32, 36, and 62 kDa). These results support the hypothesis that OPXV circulate in at least three genera of Procyonidae in Central and Southeast Mexico.

    Many countries, including Mexico, are facing a largely unrecognized epidemic of low-level lead poisoning. Mexico is the sixth largest lead-producing country in the world, and 40% of its production is used locally in different industrial processes that cause lead contamination of the environment. The major sources and pathways of lead exposure among the Mexican population are gasoline emissions, lead-glazed ceramics, leaded paint, and lead in canned foods and beverages. In this paper we present evidence for the presence of lead in different environmental media and its impact on blood lead levels of the Mexican population. Although during the last few years important measures have been implemented to decrease lead exposure, our findings suggest that lead poisoning is still an important problem in Mexico. There is an urgent need for regulatory policies that implement stricter control to protect the Mexican population. There is also a need to develop adequate programs to reduce the lead burden and the associated health effects in the population that has been chronically exposed.

    This report is about the market for airline travel in northern New Mexico. Interest in developing a northern New Mexico regional airport has periodically surfaced for a number of years. The New Mexico State Legislature passed a memorial during the 1998 Second Session calling for the conduct of a study to determine the feasibility of building a new regional airport in NNM. This report is a study of the passenger market feasibility of such an airport. In addition to commercial passenger market feasibility, there are other feasibility issues dealing with siting, environmental impact, noise, economic impact, intermodal transportation integration, region-wide transportation services, airport engineering requirements, and others. These other feasibility issues are not analyzed in any depth in this report although none were discovered to be show-stoppers as a by-product of the authors doing research on the passenger market itself. Preceding the need for a detailed study of these other issues is the determination of the basic market need for an airport with regular commercial airline service in the first place. This report is restricted to an in-depth look at the market for commercial passenger air service in NNM. 20 figs., 8 tabs.

    Serious fungal infections (SFIs) could be more frequent than are recognised. Estimates of the incidence and prevalence of SFIs are essential in order to identify public health problems. We estimated the rates of SFIs in Mexico, following a methodology similar to that used in prior studies. We obtained information about the general population and populations at risk. A systematic literature search was undertaken to identify epidemiological reports of SFIs in Mexico. When Mexican reports were unavailable, we based our estimates on international literature. The most prevalent SFIs in Mexico are recurrent vulvovaginal candidiasis (5999 per 100,000) followed by allergic bronchopulmonary aspergillosis (60 per 100,000), chronic pulmonary aspergillosis (15.9 per 100,000), fungal keratitis (10.4 per 100,000), invasive candidiasis (8.6 per 100,000) and SFIs in HIV (8.2 per 100,000); coccidioidomycosis (7.6 per 100,000), IA (4.56 per 100,000). These correspond to 2,749,159 people affected in any year (2.45% of the population), probably >10,000 deaths and 7000 blind eyes. SFIs affect immunocompromised and healthy populations. Most are associated with high morbidity and mortality rates. Validation of these estimates with epidemiological studies is required. The burdens indicate that an urgent need to improve medical skills, surveillance, diagnosis, and management of SFIs exists.

  19. Effective access to health care in Mexico

    PubMed Central

    2014-01-01

    Background Effective access measures are intended to reflect progress toward universal health coverage. This study proposes an operative approach to measuring effective access: in addition to the lack of financial protection, the willingness to make out-of-pocket payments for health care signifies a lack of effective access to pre-paid services. Methods Using data from a nationally representative health survey in Mexico, effective access at the individual level was determined by combining financial protection and effective utilization of pre-paid health services as required. The measure of effective access was estimated overall, by sex, by socioeconomic level, and by federal state for 2006 and 2012. Results In 2012, 48.49% of the Mexican population had no effective access to health services. Though this represents an improvement since 2006, when 65.9% lacked effective access, it still constitutes a major challenge for the health system. Effective access in Mexico presents significant heterogeneity in terms of federal state and socioeconomic level. Conclusions Measuring effective access will contribute to better target strategies toward universal health coverage. The analysis presented here highlights a need to improve quality, availability, and opportuneness (location and time) of health services provision in Mexico. PMID:24758691

  20. Manufacturing poverty: the maquiladorization of Mexico.

    PubMed

    La Botz, D

    1994-01-01

    Based on interviews with social workers, attorneys, feminists, union activists, and factory workers, the author argues that the maquiladora free trade zone of Northern Mexico portends developments under the North American Free Trade Agreement. Today some 500,000 Mexican workers labor in 2,000 factories for $4.50 a day in Mexico's maquiladoras. Two-thirds of the workers are women, many single women who head their households. These women work in the new, modern manufacturing plants in industrial parks, but live in squalid shantytowns without adequate water, sewage, or electricity. On the job, workers face exposures to toxic chemicals and dangerous work processes. The Mexican government does not have the political will, the trained personnel, or the equipment to monitor these occupational health problems. While Mexico's Constitution and labor laws guarantee workers the right to organize, bargain collectively, and strike, in practice the state controls the unions and opposes worker activism. In the face of employer and state repression workers are forced to organize secretly to fight for higher wages and safer conditions.

  3. Geothermal energy from deep sedimentary basins: The Valley of Mexico (Central Mexico)

    2015-04-01

    The geothermal potential of the Valley of Mexico has not been addressed in the past, although volcaniclastic settings in other parts of the world contain promising target reservoir formations. A first assessment of the geothermal potential of the Valley of Mexico is based on thermophysical data gained from outcrop analogues, covering all lithofacies types, and evaluation of groundwater temperature and heat flow values from literature. Furthermore, the volumetric approach of Muffler and Cataldi (1978) leads to a first estimation of ca. 4000 TWh (14.4 EJ) of power generation from Neogene volcanic rocks within the Valley of Mexico. Comparison with data from other sedimentary basins where deep geothermal reservoirs are identified shows the high potential of the Valley of Mexico for future geothermal reservoir utilization. The mainly low permeable lithotypes may be operated as stimulated systems, depending on the fracture porosity in the deeper subsurface. In some areas also auto-convective thermal water circulation might be expected and direct heat use without artificial stimulation becomes reasonable. Thermophysical properties of tuffs and siliciclastic rocks qualify them as promising target horizons (Lenhardt and Götz, 2015). The here presented data serve to identify exploration areas and are valuable attributes for reservoir modelling, contributing to (1) a reliable reservoir prognosis, (2) the decision of potential reservoir stimulation, and (3) the planning of long-term efficient reservoir utilization.

    Subsidence and surface faulting have affected urban areas in Central Mexico for decades and the process has intensified as a consequence of urban sprawl and economic growth. This process causes substantial damages to the urban infrastructure and housing structures and in several cities it is becoming a major factor to be considered when planning urban development, land use zoning and hazard mitigation strategies in the next decades. Subsidence is usually associated with aggressive groundwater extraction rates and a general decrease of aquifer static level that promotes soil consolidation, deformation and ultimately, surface faulting. However, local stratigraphic and structural conditions also play an important role in the development and extension of faults. Despite its potential for damaging housing, and other urban infrastructure, the economic impact of this phenomena is poorly known, in part because detailed, city-wide subsidence induced faulting risk maps have not been published before. Nevertheless, modern remote sensing techniques are most suitable for this task. We present the results of a risk analysis for subsidence induced surface faulting in two cities in central Mexico: Morelia and Mexico City. Our analysis in Mexico City and Morelia is based on a risk matrix using the horizontal subsidence gradient from a Persistent Scatterer InSAR (Morelia) and SqueeSAR (Mexico City) analysis and 2010 census population distribution data from Mexico's National Institute of Statistics and Geography. Defining subsidence induced surface faulting vulnerability within these urbanized areas is best determined using both magnitude and horizontal subsidence gradient. Our Morelia analysis (597,000 inhabitants with localized subsidence rates up to 80 mm/yr) shows that 7% of the urbanized area is under a high to very high risk level, and 14% of its population (11.7% and 2.3% respectively) lives within these areas.

    2010-01-01

    Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot support marine life, generally manifests itself in the spring. Since marine species either die or flee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational fishing in the Gulf. Since 2001, the hypoxic zone has averaged 16,500 km{sup 2} during its peak summer months, an area slightly larger than the state of Connecticut, and ranged from a low of 8,500 km{sup 2} to a high of 22,000 km{sup 2}. To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together representatives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Office of Science and Technology Policy to conduct a scientific assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR). In 2000 the CENR completed An Integrated Assessment: Hypoxia in the Northern Gulf of Mexico (or Integrated Assessment), which formed the scientific basis for the Task Force's Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico (Action Plan, 2001). In its Action Plan, the Task Force pledged to implement ten management actions and to assess progress every 5 years. This reassessment would address the nutrient load reductions achieved, the responses of the hypoxic zone and associated water quality and habitat conditions, and economic and social effects. The Task Force began its reassessment in 2005. In 2006 as part of the reassessment, USEPA's Office of Water, on behalf of the Task Force, requested that the U.S. Environmental Protection Agency (USEPA) Science Advisory Board (SAB) convene an independent panel to

    The Gulf of Mexico is a small ocean basin between the US and Mexico that opened up soon after the breakup of Pangea. Although the area has been heavily surveyed with seismic reflection profiles, the deep structure of the region is poorly understood because of lack of penetration beneath the thick sediments and salt. We present the results of two wide-angle seismic refraction profiles in the northeastern Gulf of Mexico that constrain seismic velocities and thicknesses of the sediments and crust from the continental shelf to deep ocean basin. Profile GUMBO 3 extends 523 km from offshore Alabama south-southwest via the De Soto Canyon to the central Gulf of Mexico, while GUMBO 4 extends 507 km from the northwestern Florida peninsula across the Florida Escarpment to the central Gulf of Mexico. On both profiles, ocean bottom seismometers were positioned at 12-km spacing, and recorded air gun shots at offsets >100 km. We use a tomographic inversion of first-arrival and secondary travel time picks from these data to build a layered velocity model (water, sediments, crystalline crust, mantle) along each profile. On GUMBO 3 and GUMBO 4 the thickness of crystalline crust from the continental shelf to the deep basin decreases from ~25 km to ~7 km (GUMBO 4) or ~8 km (GUMBO 3) over a horizontal distance of ~150 km. Velocities of 7-7.5 km/s are observed at the base of the crust along most of GUMBO 3, while velocities of 6.5-7 km/s are observed at similar depths along GUMBO 4. We suggest that higher lower crustal velocities, and thicker oceanic crust, on GUMBO 3 compared to GUMBO 4 may be explained by elevated syn-rift mantle temperatures in the vicinity of the De Soto Canyon and South Georgia Rift during rifting and continental breakup. We have integrated seismic refraction, seismic reflection, and well data to interpret sequence stratigraphic units along GUMBO 3 and GUMBO 4. We have constructed a geologic history of the late-Jurassic/early-Cretaceous, beginning first with Louann

    Curandera-parteras (traditional Hispanic midwives) have been in northern New Mexico since before its statehood. In the 1930s, the New Mexico Department of Health began a valuable relationship with the curandera-parteras through the Midwife Consultant Program. This article describes the relationship between the curandera-parteras and the New Mexico Department of Health originating in the 1920s. The amenable and effective working relationship achieved between curandera-parteras and public health during this time period helped create the positive support for midwifery that is apparent in New Mexico today.

    As part of the Megacities Initiative: Local and Global Research Observations (MILAGRO) study in the Mexico City Metropolitan Area in March 2006, we measured particulate polycyclic aromatic hydrocarbons (PAHs) and other gaseous species and particulate properties at six locations throughout the city. The measurements were intended to support the following objectives: to describe spatial and temporal patterns in PAH concentrations, to gain insight into sources and transformations of PAHs, and to quantify the relationships between PAHs and other pollutants. Total particulate PAHs at the Instituto Mexicano del Petróleo (T0 supersite) located near downtown averaged 50 ng m-3, and aerosol active surface area averaged 80 mm2 m-3. PAHs were also measured on board the Aerodyne Mobile Laboratory, which visited six sites encompassing a mixture of different land uses and a range of ages of air parcels transported from the city core. Weak intersite correlations suggest that local sources are important and variable and that exposure to PAHs cannot be represented by a single regional-scale value. The relationships between PAHs and other pollutants suggest that a variety of sources and ages of particles are present. Among carbon monoxide, nitrogen oxides (NOx), and carbon dioxide, particulate PAHs are most strongly correlated with NOx. Mexico City's PAH-to-black carbon mass ratio of 0.01 is similar to that found on a freeway loop in the Los Angeles area and approximately 8-30 times higher than that found in other cities. Ratios also indicate that primary combustion particles are rapidly coated by secondary aerosol in Mexico City. If so, the lifetime of PAHs may be prolonged if the coating protects them against photodegradation or heterogeneous reactions.

    Tijuana, Mexico, just south of San Diego, California, is located by the busiest land border crossing in the world. Although UNAIDS considers Mexico to be a country of “low prevalence, high risk,” recent surveillance data among sentinel populations in Tijuana suggests HIV prevalence is increasing. The aim of this study was to estimate the number of men and women aged 15 to 49 years infected with HIV in Tijuana. Gender and age-specific estimates of the Tijuana population were obtained from the 2000 Mexican census. Population and HIV prevalence estimates for at-risk groups were obtained from published reports, community based studies, and data from the Centro Nacional para la Prevención y Control del VIH/SIDA (CENSIDA). Age-specific fertility rates for Mexico were used to derive the number of low and high-risk pregnant women. Numbers of HIV-positive men and women were estimated for each at-risk group and then aggregated. A high growth scenario based on current HIV prevalence and a conservative, low growth estimate were determined. A total of 686,600 men and women in Tijuana were aged 15 to 49 years at the time of the 2000 census. Considering both scenarios, the number of infected persons ranged from 1,803 to 5,472 (HIV prevalence: 0.26 to 0.80%). The majority of these persons were men (>70%). The largest number of infected persons were MSM (N = 1,146 to 3,300) and IDUs (N = 147 to 650). Our data suggest that up to one in every 125 persons aged 15–49 years in Tijuana is HIV-infected. Interventions to reduce ongoing spread of HIV are urgently needed. PMID:16736378

    Since 1947 Petroleos Mexicanos (Pemex) has conducted oil exploration projects using potential field methods. Geophysical exploration companies under contracts with Pemex carried out gravity anomaly surveys that were referred to different floating data. Each survey comprises observations of gravity stations along highways, roads and trails at intervals of about 500 m. At present, 265 separate gravimeter surveys that cover 60% of the Mexican territory (mainly in the oil producing regions of Mexico) are available. This gravity database represents the largest, highest spatial resolution information, and consequently has been used in the geophysical data compilations for the Mexico and North America gravity anomaly maps. Regional integration of gravimeter surveys generates gradients and spurious anomalies in the Bouguer anomaly maps at the boundaries of the connected surveys due to the different gravity base stations utilized. The main objective of this study is to refer all gravimeter surveys from Pemex to a single new first-order gravity base station network, in order to eliminate problems of gradients and spurious anomalies. A second objective is to establish a network of permanent gravity base stations (BGP), referred to a single base from the World Gravity System. Four regional loops of BGP covering eight States of Mexico were established to support the tie of local gravity base stations from each of the gravimeter surveys located in the vicinity of these loops. The third objective is to add the gravity constants, measured and calculated, for each of the 265 gravimeter surveys to their corresponding files in the Pemex and Instituto Mexicano del Petroleo database. The gravity base used as the common datum is the station SILAG 9135-49 (Latin American System of Gravity) located in the National Observatory of Tacubaya in Mexico City. We present the results of the installation of a new gravity base network in northeastern Mexico, reference of the 43 gravimeter surveys

    Biological communities in Mexico experienced profound changes in species composition and structure as a consequence of the environmental fluctuations during the Pleistocene. Based on the recent and fossil Mexican mammal checklists, we determine the distribution, composition, diversity, and community structure of late Pleistocene mammalian faunas, and analyze extinction patterns and response of individual species to environmental changes. We conclude that (1) differential extinctions occurred at family, genus, and species level, with a major impact on species heavier than 100 kg, including the extinction all proboscideans and several ruminants; (2) Pleistocene mammal communities in Mexico were more diverse than recent ones; and (3) the current assemblages of species are relatively young. Furthermore, Pleistocene relicts support the presence of biogeographic corridors; important refugia existed as well as centers of speciation in isolated regions. We identified seven corridors: eastern USA-Sierra Madre Oriental corridor, Rocky Mountains-Sierra Madre Occidental corridor, Central United States-Northern Mexico corridor, Transvolcanic Belt-Sierra Madre del Sur corridor, western USA-Baja California corridor, Tamaulipas-Central America gulf lowlands corridor, and Sonora-Central America Pacific lowlands corridor. Our study suggests that present mammalian assemblages are very different than the ones in the late Pleistocene.

    The impact of air pollution on human health is a complicated problem. In this review, we describe the main health effects of exposure to ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, lead and particulate matter. Geographical characteristics of the metropolitan area of Mexico City that favor pollutant persistence with adverse effects on the population are described; the use of the Indice Metropolitano de la Calidad del Aire (IMECA), current norms, and present programs to diminish this problem are discussed. Evidence shows that through these actions, air quality has improved. However, some pollutants such as ozone and particulate matter, still exceed the standard. To further improve air quality in the city, existing programs should continue and multidisciplinary research, both basic and applied, is required.

    Exploration activity in South America, Central America, the Caribbean area, and Mexico in 1985 was concentrated in proven petroleum provinces. Successful exploration and development efforts were most intense in Colombia and Venezuela, where activity centered around the Cano Limon field area. Initial production of 30,000 BOPD from Cano Limon started in December, raising Colombia again to the ranks of an exporting nation. Another significant discovery in Colombia was San Francisco field in the Upper Magdalena basin. Argentina reported significant discoveries by YPF in the Northwest Cretaceous and Neuquen basins and by Total offshore Tierra del Fuego. Brazil continued to discover major reserves in the offshore Campos basin in ever-increasing water depths. At year end, Venezuela was drilling Furrial-1 in eastern Venezuela. The well is reported to be the outstanding discovery of 1985, if not of the last 2 decades. 4 figures, 7 tables.

We present a dataset that includes the taxonomic and geographic information of irregular echinoids from Mexico, housed in four collections: 1) Colección Nacional de Equinodermos “Ma. Elena Caso Muñoz” from the Instituto de Ciencias del Mar y Limnología (ICML), Universidad Nacional Autónoma de México (UNAM); 2) Invertebrate Zoology Collection, Smithsonian Museum of Natural History, Washington, D.C., United States of America (USA); 3) Invertebrate Collection, Museum of Comparative Zoology, University of Harvard, Boston, Massachusetts, USA and 4) Invertebrate Zoology, Peabody Museum, Yale University, New Haven, Connecticut, USA. New information A total of six orders, 17 families, 35 genera and 68 species are reported, 37 distributed in the Pacific coast and 31 in the Atlantic coast, none of them was found in both coasts. The most diverse region is the Gulf of California (S=32); the most diverse order is Spatangoida with 31 species reported in mexican waters. PMID:27660526

    The resident and migratory bat fauna of the middle Rio Grande Valley in central New Mexico is inadequately known. Many of the specimen records from this valley are from Bosque del Apache National Wildlife Refuge, ca. 20 km S of Socorro, Socorro Co. Findley et al. (1975) reported Myotis lucifugus, M. yumanensis, Lasiurus cinereus, and Tadarida brasiliensis from the refuge to which Reith (1982) added Antrozous pallidus. During June and July 1994, we netted nine nights and conducted visual searches of known roosts to capture 67 bats of seven species as part of a baseline survey of bats on the refuge. We surveyed artificial wetlands in the transitional zone between riparian forest and adjacent desert-grassland, within ca. 2 km of the Rio Grande. Nearby agricultural fields and ponds managed primarily for use by waterfowl provided numerous sites suitable for foraging and drinking by bats. We report four new species records for the refuge, one of  which is also a new county record. Voucher material is deposited in the Biological Survey Collection, Fort Collins (BS/FC), now housed in the Museum of Southwestern Biology (MSB), University of New Mexico.

    El estudio que se presenta es de caracter cualitativo, un estudio multicasos donde se estudia la estructura logica utilizada por cuatro (4) profesores universitarios que ensenan el curso introductorio de quimica, en la planificacion, presentacion y evaluacion del tema sobre el comportamiento de los gases. Se utilizaron varias fuentes de informacion como: cuestionarios de profesores y estudiantes, entrevistas, grabaciones videomagnetofonicas, materiales didacticos y una prueba conceptual, entre otros. La informacion recopilada fue analizada de acuerdo al orden logico del contenido presentado, el estilo de ensenanza del profesor, las tecnicas y estrategias utilizadas para el desarrollo de destrezas de pensamiento, el ambiente fisico en el salon de clase y los instrumentos de evaluacion y avaluo. El estudio demuestra que lo que los profesores piensan y planifican para hacer sus presentaciones no necesariamente es lo que ocurre en el salon de clases. El desarrollo de destrezas de pensamiento, que constituye una prioridad de los profesores, no se elaboran efectivamente. El uso de las estrategias de resolucion de problemas numericos predomino. La participacion del estudiante en el salon de clases fue limitada y no se logro demostrar el desarrollo de las destrezas de pensamiento deseadas. Aunque los profesores tienen su propio estilo de ensenanza, el orden logico del contenido presentado en clase fue el mismo o siguio muy de cerca el orden establecido por el libro de texto. Los profesores utilizaron preferentemente la tiza y la pizarra para sus presentaciones y la dinamica en el salon de clases fue esencialmente tradicional. Los profesores hicieron su presentacion y los estudiantes copiaron pasivamente la informacion. Las evaluaciones de los estudiantes fueron esencialmente, pruebas escritas de seleccion multiple de acuerdo con el estilo en que se les enseno. El avaluo fue casi inexistente. La prueba conceptual administrada revela un aprendizaje pobre en los conceptos mas

    While U.S. health care reform will most likely reduce the overall number of uninsured Mexican-Americans, it does not address challenges related to health care coverage for undocumented Mexican immigrants, who will remain uninsured under the measures of the reform; documented low-income Mexican immigrants who have not met the five-year waiting period required for Medicaid benefits; or the growing number of retired U.S. citizens living in Mexico, who lack easy access to Medicare-supported services. This article reviews two promising binational initiatives that could help address these challenges-Salud Migrante and Medicare in Mexico; discusses their prospective applications within the context of U.S. health care reform; and identifies potential challenges to their implementation (legal, political, and regulatory), as well as the possible benefits, including coverage of uninsured Mexican immigrants, and their integration into the U.S. health care system (through Salud Migrante), and access to lower-cost Medicare-supported health care for U.S. retirees in Mexico (Medicare in Mexico).
