    We compiled a checklist of the amphibians and reptiles of the state of Coahuila, Mexico. The list comprises 133 species (24 amphibians, 109 reptiles), representing 27 families (9 amphibians, 18 reptiles) and 65 genera (16 amphibians, 49 reptiles). Coahuila has a high richness of lizards in the genus Sceloporus. Coahuila has relatively few state endemics, but has several regional endemics. Overlap in the herpetofauna of Coahuila and bordering states is fairly extensive. Of the 132 species of native amphibians and reptiles, eight are listed as Vulnerable, six as Near Threatened, and six as Endangered in the IUCN Red List. In the SEMARNAT listing, 19 species are Subject to Special Protection, 26 are Threatened, and three are in Danger of Extinction. Coahuila is home to several species of conservation concern, especially lizards and turtles. Coahuila is an important state for the conservation of the native regional fauna.

    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.

    To determine diagnostic delay in pulmonary tuberculosis (PTB) cases and analyse associated factors. New PTB cases were studied in Coahuila, Northern Mexico, between 2008 and 2009. We obtained census data and data on residential address, symptoms and diagnosis from the national patient database; sociodemographic variables were obtained during home visits. Bivariate analyses used the Kaplan-Meier method; multivariate analysis consisted of modelling survival. We studied 458 subjects (median age 48 years), who were predominantly males (56.1%); the median years of schooling was 6.0 years, 83.4% were urban residents, 50.3% were unemployed, and 87.7% suffered from food poverty. The median delay between the onset of symptoms and the first medical consultation was 53.5 days. Lack of formal education (P = 0.050) and living ≥5 km from a health unit (P = 0.034) were associated with longer delays and consequently with severe symptoms (cough ≥2 weeks, P = 0.001; chest pain, P = 0.032; malnutrition, P = 0.003). Mean health system delay (between first consultation and smear test result) was 18.5 days, and was significantly longer when the first consultation was with a private physician (P < 0.001) and when patient age was ≥46 years (P = 0.001). In Coahuila, lack of formal education, living ≥5 km from a health unit, first consultation with a private physician, and being aged ≥46 years contributed to delays in PTB diagnosis.

    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.

    Red cell acid phosphatase types and GC polymorphisms were studied in Mérida and Oaxaca, Mexico. GC polymorphisms were also investigated in León and Saltillo. The ACP*A, ACP*B, and ACP*C gene frequencies were 0.215, 0.770, and 0.015 respectively, in Mérida and 0.205, 0.788, and 0.002, respectively, in Oaxaca. In Oaxaca the ACP*R gene had a frequency of 0.005. The results are similar to other Mestizo groups studied in Mexico; it is concluded that the ACP*C and ACP*R genes were introduced by admixture of native Amerindians with whites and blacks, respectively. The GC*1S, GC*1F, and GC*2 gene frequencies were 0.489, 0.289 and 0.222, respectively, in León; 0.500, 0.272, and 0.228, respectively, in Mérida; 0.454, 0.337, and 0.209, respectively, in Oaxaca; and 0.505, 0.356, and 0.139, respectively, in Saltillo. These results are similar to what has been obtained in other Mestizo populations and Indian groups in Mexico, probably because the main ethnic component in both is Amerindian.

  15. Evolution of Cupido and Coahuila carbonate platforms, early Cretaceous, northeastern Mexico

    The Cupido and Coahuila platforms of northeastern Mexico are part of the extensive carbonate platform system that rimmed the ancestral Gulf of Mexico during Barremian to Albian time. Exposures of Cupido and Coahuila lithofacies in several mountain ranges spanning an ???80 000 km2 area reveal information about platform morphology and composition, paleoenvironmental relations, and the chronology of platform evolution. New biostratigraphic data, integrated with carbon and strontium isotope stratigraphy, significantly improve chronostratigraphic relations across the region. These data substantially change previous age assignments of several formations and force a revision of the longstanding stratigraphy in the region. The revised stratigraphy and enhanced time control, combined with regional facies associations, allow the construction of cross sections, isopach maps, and timeslice paleogeographic maps that collectively document platform morphology and evolution. The orientation of the Cupido (Barremian-Aptian) shelf margin was controlled by the emergent Coahuila basement block to the northwest. The south-facing margin is a high-energy grainstone shoal, whereas the margin facing the ancestral Gulf of Mexico to the east is a discontinuous rudist-coral reef. A broad shelf lagoon developed in the lee of the Cupido margin, where as much as 660 m of cyclic peritidal deposits accumulated. During middle to late Aptian time, a major phase of flooding forced a retrograde backstep of the Cupido platform, shifting the locus of shallow-marine sedimentation northwestward toward the Coahuila block. This diachronous flooding event records both the demise of the Cupido shelf and the consequent initiation of the Coahuila ramp. The backstepped Coahuila ramp (Aptian-Albian) consisted of a shallow shoal margin separating an interior evaporitic lagoon from a low-energy, muddy deep ramp. More than 500 m of cyclic carbonates and evaporites accumulated in the evaporitic lagoon during early to

    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.

    While centrosaurines and ceratopsids in general are abundant in the Late Campanian of northern Laramidia, they are much less commonly found in southern Laramidia. This has supported hypotheses of dinosaur provinciality and endemism in the Late Cretaceous with the delineation of at least two separate faunal zones, north and south Laramidia. There have been 12 genera of centrosaurines recognized from northern Laramidia while two genera, Diabloceratops and Nasutoceratops, have been named from southern Laramidia. We present an osteological description and taphonomic outline for a new centrosaurine ceratopsid from the Aguja Formation of northern Coahuila, Mexico that is not currently diagnosable to the generic level, but likely represents a new taxon. Further, we have included three-dimensional surface scans of all material attributed to this animal. Considering the large number of centrosaurines from northern Laramidia, it is likely that cladistic analyses are biased towards this faunal zone. New findings of southern centrosaurines are needed to correct this bias. This discovery expands the range of centrosaurines south to Coahuila, Mexico and adds new information to better characterize the morphology and taxonomy of centrosaurines from southern Laramidia and their evolution in comparison to their northern counterparts.

    The Olmos Formation was part of a system of deltas that existed in the southern portion of the Western Interior of North America during the Campanian-Maastrichtian. The paleofloristic composition from the northern portions of the Epicontinental Sea is relatively well known, but less intensive exploration in the south has precluded more detailed floristic comparison across the entire latitudinal span of the Sea. The Olmos Formation flora, with more than 100 different leaf morphotypes so far recognized and several wood types, has the most diverse Cretaceous fossil plant assemblage in Mexico and represents a valuable opportunity for comparative studies. • The fossil woods here described were collected in the Coahuila State, Mexico. The samples were studied using standard thin section technique and identified by comparison with fossil and extant material. • We described four new genera (Olmosoxylon, cf. Lauraceae; Coahuiloxylon, ?Anacardiaceae, ?Burseraceae; Muzquizoxylon, Cornaceae; and Wheeleroxylon, Malvaceae s.l.) and three xylotypes of angiosperms. • Some of the genera present in the Olmos Formation such as Javelinoxylon and Metcalfeoxylon have been described from geologic units in the USA (San Juan Basin, New Mexico and Big Bend National Park, Texas), suggesting similarity in the taxonomic composition of the floras that inhabited southern portions of the western margin of the Campanian-Maastrichtian Epicontinental Sea. Other species, however, have only been reported for the Olmos Formation, indicating some degree of local floristic differentiation among the assemblages that inhabited the southern portion of the Western Interior.

    72 specimens of ammonites and the nautilid Eutrephoceras, collected from the upper Cretaceous Parras Shale at Saucedas in southern Coahuila, Mexico, are here assigned to twelve genera and fourteen species. The assemblage represents three to four upper Campanian biozones reaching from the Western Interior lower upper Campanian Exiteloceras jenneyi to the uppermost Campanian Tethyan Nostoceras hyatti biozone. Eutrephoceras irritilasi and Trachyscaphites sp. are endemic taxa, while Baculites taylorensis is restricted to the northern Gulf of Mexico Coast and E. jenneyi, Oxybeloceras crassum and Solenoceras elegans are Western Interior Seaway elements. Didymoceras donezianum is a southern Euramerican species, while Bostrychoceras polyplocum and N. hyatti occur throughout lower and middle latitudes. Diplomoceras cylindraceum and Phyllopachyceras forbesianum are cosmopolitan taxa with their main occurrences in the Maastrichtian; their record at Saucedas is the oldest of these species in North America. A clear paleobiogeographic signal is identified in the upper Campanian ammonite assemblages at Saucedas by a change from restricted towards geographically widespread faunas. This suggests gradual disappearence of faunal barriers which separated the Gulf Coast from the rest of the world.

    The Cities of Ciudad Acuna and Piedras Negras and the State of Coahuila in Mexico are interested in improving ambient air quality monitoring capabilities in the two cities through the establishment of a network of ambient air monitors. The purpose of the network is to characterize population exposure to potentially harmful air contaminants, possibly including sulfur dioxide (SO{sub 2}), nitrogen oxides (NO{sub x}), ozone (O{sub 3}), carbon monoxide (CO), total suspended particulate matter (TSP), particulate matter with aerodynamic diameter less than 100 micrometers PM-10, and lead. This report presents the results of an evaluation of existing air quality monitoring equipment and facilities in Ciudad Acuna and Piedras Negras. Additionally, the report presents recommendations for developing an air quality monitoring network for PM-10, SO{sub 2}, lead, and ozone in these cities, using a combination of both new and existing equipment. The human resources currently available and ultimately needed to operate and maintain the network are also discussed.

    The iron concentrate from Hercules Mine of Coahuila, Mexico, which mainly contained pyrite and pyrrhotite, was treated by the bioleaching process using native strain Acidithiobacillus ferrooxidans ( A. ferrooxidans) to determine the ability of these bacteria on the leaching of zinc. The native bacteria were isolated from the iron concentrate of the mine. The bioleaching experiments were carried out in shake flasks to analyze the effects of pH values, pulp density, and the ferrous sulfate concentration on the bioleaching process. The results obtained by microbial kinetic analyses for the evaluation of some aspects of zinc leaching show that the native bacteria A. ferrooxidans, which is enriched with a 9K Silverman medium under the optimum conditions of pH 2.0, 20 g/L pulp density, and 40 g/L FeSO4, increases the zinc extraction considerably observed by monitoring during15 d, i.e., the zinc concentration has a decrease of about 95% in the iron concentrate.

    The Cuatro Ciénegas Basin (CCB) is a rare oasis in the Chihuahuan Desert in the state of Coahuila, Mexico. It has a biological endemism similar to that of the Galapagos Islands, and its spring-fed ecosystems have very low nutrient content (nitrogen or phosphorous) and are dominated by diverse microbialites. Thus, it has proven to be a distinctive opportunity for the field of astrobiology, as the CCB can be seen as a proxy for an earlier time in Earth's history, in particular the late Precambrian, the biological frontier when prokaryotic life yielded at least partial dominance to eukaryotes and multicellular life. It is a kind of ecological time machine that provides abundant opportunities for collaborative investigations by geochemists, geologists, ecologists, and population biologists in the study of the evolutionary processes that structured Earth-based life, especially in the microbial realm. The CCB is an object of investigation for the identification of biosignatures of past and present biota that can be used in our search for extraterrestrial life. In this review, we summarize CCB research efforts that began with microbial ecology and population biology projects and have since been expanded into broader efforts that involve biogeochemistry, comparative genomics, and assessments of biosignatures. We also propose that, in the future, the CCB is sanctioned as a "Precambrian Park" for astrobiology.

  7. Fluid Origin of the Stratabound Fluorite and Celestite Deposits in Coahuila, Mexico.

    The Mesozoic units that outcrop north of Coahuila State in northern Mexico host numerous celestite, celestite-fluorite and fluorite deposits, mainly enclosed in the Cretaceous limestone units. Celestite and celestite-fluorite deposits are lens-shaped bodies, up to 2 m thick and a total length exceeding 500 meters, intercalated within the carbonates of the Cupido Formation (Aptian) or equivalents. Celestite-free fluorite bodies, mainly enclosed in the Aurora Formation (Albian-Cenomanian), appear as sub-concordant lenses with abundant evidences of hydraulic fracturing, usually near low-angle fractures. The celestite brine halogen composition on a Cl/Br vs Na/Br molar ratio plot on the trend defined by the evaporation of seawater, while in a ppm Cl vs Cl/Br plot away from the seawater evaporation line but parallel to it, indicating that the solution was mainly modified by dilution. The fluids involved in the genesis of the La Encantada fluorite deposit probably are evolved seawater that undergone some degree of evaporation. Mixing of fluids is clearly delineated by both microthemometric and halogen data, where salinities calculated are too low for the halogen ratios found, indicating a mixing with a low-salinity end-member. Hydrocarbon-bearing fluid inclusions repeatedly show the presence of solid bitumen trapped along with heavy oils, indicative of thermal degradation. Both, mixing and thermal degradation of hydrocarbon-rich fluids along with hydraulic fracture of the host rock points to an "in situ" organic matter maturation, due to the mixing of a saline, oxidant, sulphate and CaCl2-rich "bittern", which probably transported fluorite, with an organic-matter rich fluid present in the cretaceous carbonates. It is noteworthy that these previous results suggest that both celestite and fluorite-dominated deposits formed from brines from similar origin, showing the same halogen systematics. Strontium enrichment can be explained by leaching of Sr from the carbonate series

Aquifers are characterized using geographic information systems (GIS) for groundwater catchment delineation, an analytical model for interbasin flow evaluation, a chloride balance approach for recharge estimation, and a water budget for mapping contributing catchments over a 160,000 km2 region (24.87° to 28.70° north latitude and 100.68° west to 104.75° west longitude). The study area includes the Cuatro Cienegas Basin (CCB) of Coahuila, Mexico, a National Biosphere Reserve containing springs that support groundwater-dependent ecosystems and irrigated agriculture. Sustainable groundwater development is a key issue on the U.S. Mexico border. However, these procedures may be applicable in similar settings globally. We delineate groundwater catchments that contribute local and regional groundwater discharge to CCB springs and identify a large regional flow system includes mountain recharge from as both the Sierra Madre Oriental and Occidental.

    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.

    Context and Objective: Chagas disease is considered a worldwide emerging disease; it is endemic in Mexico and the state of Coahuila and is considered of little relevance. The objective of this study was to determine the seroprevalence of T. cruzi infection in blood donors and Chagas cardiomyopathy in patients from the coal mining region of Coahuila, Mexico. Design and Setting: Epidemiological, exploratory and prospective study in a general hospital during the period January to June 2011. Methods: We performed laboratory tests ELISA and indirect hemagglutination in three groups of individuals: 1) asymptomatic voluntary blood donors, 2) patients hospitalized in the cardiology department and 3) patients with dilated cardiomyopathy. Results: There were three levels of seroprevalence: 0.31% in asymptomatic individuals, 1.25% in cardiac patients and in patients with dilated cardiomyopathy in 21.14%. Conclusions: In spite of having detected autochthonous cases of Chagas disease, its importance to local public health remains to be established as well as the details of the dynamics of transmission so that the study is still in progress.

    Bees and flies are the main pollinators responsible for the maintenance of plant diversity and crop production. Studies of pollinator communities have focused on bees; however, community structures may vary among groups of pollinators. We describe and compare the diversity and resource use patterns of six Apoidea and two Diptera anthophile families in Cuatro Ciénegas in the northeast of Mexico. We sampled insects in two distinct geographic units (valley and mountains) and two seasons (rainy and dry). Spatial and temporal patterns in species composition and abundance of these families were identified and the diversity in each family compared. The spatial and temporal patterns in species composition, diversity, and resource use were different for each family. Overall, diversity was higher during the rainy season. Only fly families and the Andrenidae presented season-specific differences in species composition, in contrast with the other Apoidea. Two bee families visited more plant species per insect species during the rainy season, whereas flies visited the same number of plant species in both seasons. Apidae, Megachilidae, and Bombyliidae visited more plant species in the mountains, while the other families exhibited no differences between the mountains and the valley. The variation in the community structures of each group may reflect distinct life histories, resources needs during larval stages, and foraging behaviors. These differences are relevant in management and conservation programs that could benefit one group of pollinators while harming others with different characteristics. The traits of some families indicate their potential value as pollinators. © The Authors 2016. Published by Oxford University Press on behalf of Entomological Society of America. All rights reserved.

    Isolated thermal springs and associated aquatic environments near Cuatro Ciénegas, in north-central Mexico provide an opportunity to study patterns of evolutionary diversification under extreme conditions. Significant differences in temperature, seasonality, pH, and salinities among other variables may allow for high levels of differentiation and endemism. Biological studies of the unique faunas in this type of environment may serve as analogues for extreme and/or evaporitic environments as targeted by astrobiological research. The endemic hydrobiid gastropod \\textit{Mexipyrgus} is widely distributed in a variety of aquatic environments within the Cuatro Cienégas basin. Original description of this genus by Taylor listed six distinct species reflecting shell and anatomical features. Later revision by Hershler suggests that this diversity be reduced to one single, highly-variable species, based mainly on the morphology of reproductive structures. The systematic conflict emphasizes the need to understand the bases of morphological variation at small scales and in environmentally unusual settings. Shells of \\textit{Mexipyrgus} were collected from six localities and the following species were identified based on Taylor's classification: \\textit{M. carranzae}, \\textit{M. escobedae}, \\textit{M. multilineatus}, and specimens intermediate in character between \\textit{M. carranzae}, \\textit{M. lugoi} and \\textit{M. mojarralis}. All specimens consisted of 4-6 whorls. Shell shape was archived by the digitization of geometrically homologous landmarks on the spire (apex, whorl sutures in apertural view) and aperture. Shell size was calculated as Centroid Size. Data were analyzed using uniform and principal warp analysis of raw landmark coordinates, followed by relative warp analysis of uniform and partial warp scores. Three separate analyses were performed for 4, 5 and 6 whorled specimens. Results indicate two different levels of variation based on individual age

    Allele frequencies for the ABO, Rh, MNSs, Duffy, Kidd, Lutheran, P and Lewis blood group systems in 207 persons whose 4 grandparents were born in the Monterrey Metropolitan area (MMA), grouped into 3 generations, were ascertained along with other related population from the MMA, Mestizos from Saltillo, Coahuila and Tlaxcala, and from the populations thought to have contributed to their genetic constitution (native Mexican Indians and Spanish). Genetic admixture and distance estimates were calculated. Gene frequencies of the three generations from MMA are intermediate to those of the ancestral populations, indicating that they are Mestizo but with a genetic structure different from Mestizos of Saltillo and Tlaxcala. Both genetic admixture and distance estimates indicate that the oldest generation exhibits the greatest Spanish influence which decreases in the youngest generation and in the other MMA populations as a result of the immigration from the central states of Mexico.

    In the San Marcos ranges of Cuatrociénegas, NE Mexico, several sediment-hosted copper deposits occur within the boundary between the Coahuila Block, a basement high mostly granitic in composition and Late Paleozoic to Triassic in age, and the Mesozoic Sabinas rift basin. This boundary is outlined by the regional-scale synsedimentary San Marcos Fault. At the basin scale, the copper mineralization occurs at the top of a ˜1000 m thick red-bed succession (San Marcos Formation, Berrisian), a few meters below a conformable, transitional contact with micritic limestones (Cupido Formation, Hauterivian to Aptian). It consists of successive decimeter-thick roughly stratiform copper-rich horizons placed just above the red-beds, in a transitional unit of carbonaceous grey-beds grading to micritic limestones. The host rocks are fine- to medium-grained arkoses, with poorly sorted and subangular to subrounded grains. The detrital grains are cemented by quartz and minor calcite; besides, late iron oxide grain-coating cement occurs at the footwall unmineralized red-beds. The source area of the sediments, indicated by their modal composition, is an uplifted basement. The contents of SiO 2 (40.70-87.50 wt.%), Al 2O 3 (5.91-22.00 wt.%), K 2O (3.68-12.50 wt.%), Na 2O (0.03-2.03 wt.%) and CaO (0.09-3.78 wt.%) are within the ranges expected for arkoses. Major oxide ratios indicate that the sedimentary-tectonic setting was a passive margin. The outcropping copper mineralization essentially consists in a supergene assemblage of chrysocolla, malachite and azurite. All that remains of the primary mineralization are micron-sized chalcocite grains shielded by quartz cement. In addition, pyrite subhedral grains occur scattered throughout the copper-mineralized horizons. In these weathered orebodies copper contents range between 4.24 and 7.72 wt.%, silver between 5 and 92 ppm, and cobalt from 8 to 91 ppm.

    As part of an ongoing inventory of the helminth parasites of freshwater fishes in Mexico, 570 individual fish were collected between Apr 2008 and Oct 2011 in 26 localities along the Cuatro Ciénegas region in Coahuila State, northern Mexico. Seventeen species of hosts, mostly corresponding to Nearctic freshwater elements, were studied. A total of 8324 individual worms were collected during this survey, representing 25 species of helminths, of which 9 were digeneans, 3 monogeneans, 3 acanthocephalans, 9 nematodes and 1 cestode. Most of the records in this checklist represent new host or locality records. The information provided in this checklist may be helpful for our understanding of the biodiversity and historical biogeography of this host-parasite system, because in the Cuatro Ciénegas region occur a Nearctic freshwater fish fauna, along with Neotropical and endemic elements, and from a biogeographical point of view, this may represent a transitional area. © 2013 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

    A moderately halophilic, Gram-positive and rod-shaped bacterium, strain m4-4T, was isolated from a Chihuahuan desert lagoon in Cuatro Ciénegas, Coahuila, Mexico. Strain m4-4T was found to grow optimally at 30-37 degrees C, pH 7.0-8.0 and 5 % NaCl and to tolerate from 0.5 % to 10 % NaCl. It was shown to be aerobic. The genomic DNA G+C content was about 37 mol%. Strain m4-4T exhibited minimal or no growth on most sugars tested. Its major cellular fatty acids were C14 : 0, C16 : 0 and C18 : 1. Based on phylogenetic analysis of 16S rRNA and recA gene sequences, we observed that the closest relatives of the isolate are moderately halophilic Bacillus species, with 16S rRNA gene sequence similarity ranging from 96.6 to 97.4 % (Bacillus marisflavi, Bacillus aquimaris and Bacillus vietnamensis). Additionally, using genomic data it was determined that the type strain contains a total of nine rRNA operons with three slightly different sequences. On the basis of phenotypic and molecular properties, strain m4-4T represents a novel species within the genus Bacillus, for which the name Bacillus coahuilensis sp. nov. is proposed, with the type strain m4-4T (=NRRL B-41737T =CECT 7197T).

    Few biostratigraphic data exist from the Parras and La Popa basins, mainly due to the absence of index fossils. This paper describes 19 ammonoid species from 15 genera and 1 nautilid from La Parra, southeastern Coahuila, Mexico. The assemblage consists of Tethyan [( Baculites ovatus, Brahmaites ( Anabrahmaites) vishnu, Fresvillia constricta, Hauericeras rembda, Pachydiscus ( P.) ex gr. neubergicus, Solenoceras reesidei, Tetragonites cf. superstes], cosmopolitan ( Anagaudryceras politissimum, Desmophyllites diphylloides, Diplomoceras cylindraceum, Gaudryceras kayei, Phyllopachyceras forbesianum, Pseudophyllites indra), and cold water taxa [ Fresvillia teres, Hypophylloceras ( Neophylloceras) surya, H. ( N.) hetonaiense, Pachydiscus ( P.) cf. egertoni]. Eutrephoceras sp. and Menuites juv. sp. were not determined to species level. A similar assemblage was recently described from the coeval Méndez Formation at Cerralvo, Nuevo León. Species endemic to North America, particularly the Western Interior Seaway, are absent at La Parra. The ammonoid assemblage and associated planktonic foraminifers allow for precise biostratigraphic assignation to the early Maastrichtian planktonic foraminiferal zone CF 5, and thus provide an important marker level for correlation of the lower Difunta Group. The new biostratigraphic data presented herein allow for the first time precise dating of the Cañon del Tule Formation of the Difunta Group. Their combination with existing sequence- and magnetostratigraphic data improve the correlation of the lower Difunta Group with time-equivalent lithostratigraphic units such as the Cárdenas Formation in Mexico. They also provide new insight into ammonoid migration patterns induced by sea-level changes. Baculites ovatus migrated into the La Popa Basin as a result of the sea-level highstand documented at La Parra.

    Background There are precedents that suggest gender differences in the relationship of lead in blood with serum total IgE. The aim of this study was to evaluate in a population of teenagers attending 9 schools in Torreon, Coahuila, the relationship of lead in blood with total IgE and their dependence on gender. Methods We included 230 teenagers (105 females, 125 males) between 11 and 14 years of age, from a cohort of children evaluated for its history of lead exposure since 2000. Clinical diagnosis was performed to detect allergies; skin tests were applied for 47 common allergens in the region. IgE levels were quantified in serum by chemiluminescence and the blood lead levels by spectrophotometry AAS. Results The average blood lead levels in allergic group were of 4.86 ± 2.9 μg/dL and in the non-allergic group 5.1 ± 2.7 μg/dL. There were not gender differences between allergic group versus non allergic group, however, among the types of allergic diseases, a higher percentage of males had rhinitis, conjunctivitis and asthma, compared with the females. The blood lead level in males was significantly higher (5.61 ± 3.3 mg/dL) compared with females (4.22 ± 2.1 mg/dL) and the regression analysis between blood lead levels with total IgE was significant in males and not in females. Conclusions Gender differences observed appear to be explained by blood lead levels, however, we should consider the contribution of other variables in the model.

    Since 1992, numerous sinkholes have developed northwest of the Amistad Reservoir dam on the Rio Grande. Increases in the discharge of springs south of the dam, on the western side of the Rio Grande, in Coahuila, Mexico, have been documented. In 1995 the Mexico Section of the International Boundary and Water Commission (IBWC) completed a study of the western embankment (Coahuila, Mexico) of the dam that included surface geophysics, borehole geophysics, and installation of piezometers to learn more about subsurface conditions. As part of a 5-year safety inspection in 2005, technical advisors recommended that one line of similarly constructed piezometers be installed on the eastern embankment (Val Verde County, Texas) of the dam for comparison of water levels (potentiometric head) on both the western and eastern embankments of Amistad Reservoir dam. To provide technical assistance for the horizontal and vertical placement of piezometers on the eastern embankment of Amistad Reservoir dam, the U.S. Geological Survey, in cooperation with the U.S. Section of the IBWC, conducted a study along both the western and eastern embankments of Amistad Reservoir dam. The study involved an integrated approach using surface and borehole geophysical methods. In the western embankment investigation, geological and geophysical characteristics that indicate relatively large water-yielding properties of the Salmon Peak Formation were identified. The direct-current (DC) resistivity method was selected as the surface geophysical reconnaissance technique to correlate relatively large water-yielding properties of the Salmon Peak Formation, identified from analysis of borehole geophysical logs, with variations in subsurface resistivity. The dipole-dipole array and the reciprocal Schlumberger array were selected as the most applicable DC resistivity arrays. Two resistivity units were identified in both the dipole-dipole array data and the reciprocal Schlumberger array data along DC resistivity

    The Sierra Mojada district consists of multiple types of mineral concentrations ranging from polymetallic sulfide deposits, 'non-sulfide Zn' deposits (separate smithsonite and hemimorphite zones), and a Pb carbonate manto hosted by Upper Jurassic to Lower Cretaceous carbonates. The district is typically grouped with other polymetallic carbonate replacement deposits of southwestern North America, but the intrusive rocks that commonly are associated with these types of deposits are not known at Sierra Mojada. The Sierra Mojada district located near the boundary of the Coahuila Platform and the Sabinas Basin that formed during Late Jurassic and Cretaceous tectonic extension. The east-trending San Marcos fault runs through the Sierra Mojada district and is thought to have acted as the major conduit for basinal fluids, responsible for local dolomitization, sulfide mineralization, and petroleum in the region. The polymetallic sulfides are the stratigraphically and structurally highest ore zone and occur north of the San Marcos fault. Non-sulfide Zn (hemimorphite, smithsonite and sauconite) and lead (cerussite) concentrations occur south of the fault in the Aurora and La Pena Formations. The Iron Oxide Manto consists of stratabound zones of dominantly of hemimorphite pore-filling in Fe-oxide rich dolostones giving the ore a distinct red to orange color. The Smithsonite Manto has distinct karst features, including internal sediments interbanded with smithsonite in the lower part of the orebody. The non-sulfide Zn ores are being studied to document their morphologies, growth patterns, and paragenetic relationships using conventional petrography, SEM, and CL-based ESEM. In the Smithsonite Manto, banded and colloform smithsonite consists of aggregates of rhombohedral crystals that grew into open space and also occurs within internal sediment bands with hemimorphite or Zn clays and Zn oxides. Black dendrites of Mn oxides with Fe oxides are encased in banded smithsonite

    A major problem in paleobotany and paleoclimatology is the origin of modern tropical and paratropical rainforests. Studies of leaf macrofossils, beginning with those of Wolfe and Upchurch, have suggested that tropical and paratropical (i.e., megathermal) rainforests with dominant angiosperms are of Cenozoic origin, and that comparable vegetation was either absent or greatly restricted during the Late Cretaceous. Earth System modeling studies, in contrast, predict the existence of megathermal rainforest vegetation during the mid- and Late Cretaceous, though with less areal extent than during the Late Cenozoic and Recent. Megathermal climate with year-round precipitation is simulated along the paleoequator and along the northern margin of the Tethys Ocean, and tends to occur in highly focused regions, in contrast to the more latitudinally zoned pattern of the Recent. Low-resolution climatic indicators, such as the distribution of coals and tree fern spores, are consistent with evidence from climate modeling for megathermal wet climates during the Late Cretaceous, and by extension megathermal rainforest vegetation. However, corroborative data from plant macrofossil assemblages is needed, because the physiognomy of leaves and woods directly reflects plant adaptation to the environment and can estimate climate independently of the generic and familial affinities of the paleoflora. Newly collected plant macrofossil assemblages from the late Campian to early Maastrichtian Olmos Formation of Coahuila, Mexico, provide evidence for megathermal rainforest vegetation on the northern margin of the Tethys Ocean at approximately 35 degrees paleolatitude. The newly collected leaf flora is 72 percent entire- margined and has abundant palms, features typical of modern megathermal rainforests. Thirty percent of the species have large leaves, and 50 percent of the species have drip tips, features indicative of wet conditions. Simple and multiple regression functions based on the

    Nine Gram-negative, rod-shaped, non-spore-forming isolates with identical or very similar repetitive-sequence-based PCR profiles were recovered from an evaporative lagoon in Mexico. Two strains, designated 1N(T) and 3N, had virtually identical 16S rRNA gene sequences and, on the basis of these sequences, were identified as members of the genus Pseudomonas, with Pseudomonas peli R-20805(T) as the closest relative. All nine isolates had practically identical whole-cell protein profiles. The major fatty acids [C(16 : 0,) C(18 : 1)omega7c and summed feature a (C(16 : 1)omega7 and/or C(16 : 1)omega6c)] of strains 1N(T) and 3N supported their affiliation with the genus Pseudomonas. The DNA-DNA reassociation values with respect to P. peli LMG 23201(T) and other closely related Pseudomonas species were <15 %. Physiological and biochemical tests allowed phenotypic differentiation of the strains analysed, including strain 1N(T), from the five phylogenetically closest Pseudomonas species. On the basis of the data obtained by using this polyphasic taxonomic approach, the nine strains represent a novel species, for which the name Pseudomonas cuatrocienegasensis sp. nov. is proposed. The type strain is 1N(T) (=LMG 24676(T)=CIP 109853(T)).

    Background There are precedents to suggest that lead exposure may increase the severity of allergic disease in children. In Torreon Coahuila is known the problem of lead contamination and its association with the body burden in children. The aim of this study was to evaluate clinical and biochemical characteristics of allergic disease in children living in areas at risk of lead exposure. Methods We included children between 6 and 11 years old with clinical diagnosis of allergy, who were attending by allergic consultation in the Center of attention Heavy Metals in Torreon, Coahuila, Mexico. Medical evaluation was performed following the diagnostic criteria described by ARIA, Global Initiative for Asthma and the Hanifin and Rajka criteria for atopic dermatitis. Skin tests were applied to 47 common allergens in the region. Were quantified in serum, the levels of IL-4, IFN-γ and IgG4 by ELISA, total IgE levels by chemiluminescence and lead in blood by spectrophotometry AA. Results We present the results of 33 patients (16 girls/17 boys) aged 8 ± 1.38. The main risk factors for allergy were current animal contact (66.7%), past animal exposure (60.6%) and passive smoking (51.5%). The predominant allergy diseases: rhinitis (97%), conjunctivitis (43.8%) and atopic dermatitis (33.3%). The allergens with the higher prevalence of responses were: thickets (91.2%) and grass (88.2%). The average blood lead level was 4.36 μg/dL ± 2.13 and median total IgE 660 IU/mL. We present the analysis of the levels of cytokines, total IgE and IgG4 according to the types of allergy, severity and frequency of the disease. Conclusions IgE levels according to the type of allergic disease, severity and frequency seem to be related to the balance IL-4/INF g. The IgG4 seems to be positively related to total IgE levels in rhinitis, conjunctivitis and dermatitis and negatively with Asthma and other allergies. No association was found between blood lead levels and total IgE.

    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%.

    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.

    The health condition in Mexico was bad around de beginning of the revolutionary period. The movement of troops led the development of epidemics like yellow fever, typhus, smallpox, and influenza that were enhance with natural disasters and hunger in whole country, from cost to cost and in the north big cities like Monterrey, Guadalajara and Saltillo. Doctor Liceaga conducted a well planned campaign against yellow fever eradicating water stagnant deposits in order to combat the vector transmission, the Aedes aegypti, mosquito with satisfactory results. The first smallpox epidemic in the XX Century in Mexico was in 1916. The Mexican physicians used the smallpox vaccine against this epidemic. An American physician named Howard Taylor Ricketts arrived to Mexico for studying the typhus transmission. Accidentally he had been infected and finally, he died from typhus. Definitively, the epidemics predominate along de revolutionary period in Mexico.

  3. Structure and tectonics of the Sierra Madre oriental fold-thrust belt near Monterrey, northeastern Mexico

    1991-03-01

    The Monterrey salient was examined using Landsat TM and MSS images to determine factors controlling the development, distribution, and exposure of Laramide structures. Lateral Mesozoic facies changes influence structural styles and distribution. Exposure of deep foreland structures north of Monterrey is partly related to the location of the Cupido reef trend. Structure along the front of the salient changes abruptly from tectonic wedging to normal overthrusting where deltaic clastics of the Difunta Group grade into incompetent Mendez shale. Salt thickness is an important factor controlling structural development. Areas without evaporites are usually persistent basement highs characterized by less severe deformation. Areas with thin evaporites have complex structural styles, depending on stratigraphy, depth of exposure, and distance from the Sierra Madre thrust front. Thick salt, apparently in a Jurassic rift beneath the salient, facilitated the northward transport of thrust sheets. Late Cretaceous salt movement influenced stratigraphy in La Popa basin where limestone lenses developed in the clastic Difunta Group. Basement topography is the major factor controlling development, style, distribution of structures, and areal distribution of salt and lateral facies changes. The authors propose a tectonic model that explains the large scale structural styles in the region. The Coahuila basement-high block acted as a buttress during Laramide shortening, limiting northward progression of deformation west of Saltillo. East, in the Monterrey salient, the effect of deeper basement and thick salt permitted thrusts to transport material much farther north, resulting in development of a north-south zone of distributed left-lateral shear in the region of Saltillo.

    Entomopathogenic fungi were collected from soil in four adjacent habitats (oak forest, agricultural soil, pine reforestation and chaparral habitat) in Saltillo, México using the insect bait method with Tenebrio molitor (L.) (Coleoptera: Tenebrionidae) larvae as bait. Overall, of the larvae exposed to soil, 171 (20%) hosted Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae), 25 (3%) hosted Metarhizium anisopliae (Metschnikoff) Sorokin (Hypocreales: Clavicipitaceae) and 1 (0.1%) hosted lsaria (=Paecilomyces) sp. (Hypocreales: Cordycipitaceae). B. bassiana was significantly more frequent on larvae exposed to oak forest soil. M. anisopliae was significantly more frequent on larvae exposed to agricultural soil. From the infected bait insects, 93 isolates of B. bassiana and 24 isolates of M. anisopliae were obtained. Strains were tested for their infectivity against Cuban laurel thrips, Gynaikothrips uzeli Zimmerman (Thysanoptera: Phlaeothripidae) and the greenhouse whitefly, Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae). B. bassiana isolates caused the highest mortality on thrips (some causing 88% mortality after 6 days); both fungal species caused similarly high mortality levels against whiteflies (75%) after 6 days. Large amounts of germplasm of entomopathogenic fungi, fundamentally B. bassiana and M. anisopliae, exist in the habitats sampled; pathogenicity varied among strains, and some strains possessed significant virulence. Soils in these habitats are reservoirs of diverse strains with potential for use in biocontrol. PMID:21521145

    The objectives of this study were to determine the prevalence of antibodies against brucellosis, leptospirosis, infectious bovine rhinotracheitis virus, and bovine viral diarrhea virus (BVDV) in white-tailed deer (Odocoileus virginianus) in northeastern Mexico. Deer (n=521) were captured from helicopter using a netgun on 15 ranches covering 62,114 ha in the states of Coahuila, Nuevo Leon, and Tamaulipas during spring 2004. The prevalence of antibodies against Leptospira, infectious bovine rhinotracheitis, BVDV, and brucellosis were 5.6, 41.1, 63.5, and 0%, respectively, indicating that white-tailed deer and cattle may share disease agents when cohabiting in northeastern Mexico.

  6. Hydrochemical Investigation of Groundwaters of The Cuatro CiÉnegas Bolson, Coahuila, MÉxico

    Water samples were collected from a series of springs, pools, and canals within the Cuatro Ciénegas Bolson, Coahuila, México and analyzed for stable oxygen and hydrogen isotopes. The ?oxigen-18 values of these waters ranged from a low of -8.2 up to -5.7 , with a mean (+/- standard deviation) of -6.5 +/- 0.82 , whereas ?deuterium ranged from -52 to -43 , with a mean (+/- standard deviation) of - 46.6 +/- 3.2 . The majority of the water samples plot sub-parallel and beneath the local meteoric water line, with those sample collected furthest from spring-line exhibiting the most enriched ?oxigen-18 values. The stable isotope data indicate isotopic enrichment of groundwaters by evaporation following discharge and subsequent surface flow. The isotope data suggests that a considerable fraction of Cuatro Ciénegas groundwaters originate via local recharge. Those springs that issue from the western base of the Sierra de San Marcos mountain range are chiefly recharged within these mountains, whereas groundwaters discharging from Laguna Anteojo in the northern part of the bolson are more likely recharged within the higher San de la Madera mountain range. A preliminary water balance estimate, however, that interbas in flow must also contributes to the considerable groundwater discharge within the bolson.

    Rocky Mountain spotted fever, a tick-borne zoonosis caused by Rickettsia rickettsii, is among the most lethal of all infectious diseases in the Americas. In Mexico, the disease was first described during the early 1940s by scientists who carefully documented specific environmental determinants responsible for devastating outbreaks in several communities in the states of Sinaloa, Sonora, Durango, and Coahuila. These investigators also described the pivotal roles of domesticated dogs and Rhipicephalus sanguineus sensu lato (brown dog ticks) as drivers of epidemic levels of Rocky Mountain spotted fever. After several decades of quiescence, the disease re-emerged in Sonora and Baja California during the early 21st century, driven by the same environmental circumstances that perpetuated outbreaks in Mexico during the 1940s. This Review explores the history of Rocky Mountain spotted fever in Mexico, current epidemiology, and the multiple clinical, economic, and social challenges that must be considered in the control and prevention of this life-threatening illness.

    The springs of the Cuatro Ciénegas bolson (Four Marshes basin), Coahuila, México, support more than 70 endemic species of biota. The specifics of the groundwater flow regime, however, remain a mystery. Water samples were collected from a series of springs and pools and one canal in the Cuatro Ciénegas bolson and analyzed for field parameters (temperature, pH, conductivity, alkalinity) and stable oxygen and hydrogen isotopes in an attempt to begin a systematic study of the hydrogeology of the region. Groundwaters discharging directly along a fault-controlled spring line in Cretaceous carbonate rocks of the Cupido-Aurora aquifer are the most dilute (lowest conductivities) and warmest of those sampled. Cuatro Ciénegas waters are characterized by circumneutral pH (6.9-7.7) and reasonably low alkalinity (160-215 mg/kg as HCO 3). The δ18O values of Cuatro Ciénegas waters range from -8.2 to -5.7‰, with a mean of -6.5±0.82‰, whereas δD ranges from -52 to -43‰, with a mean of -46.6±3.2‰. The majority of the water samples plot subparallel and beneath the local meteoric water line; those samples collected farthest from the spring line exhibit the most enriched δ18O and δD values. The stable isotope data indicate that isotopic enrichment of groundwaters by evaporation following discharge and subsequent surface flow is an important process within the Cuatro Ciénegas bolson. The isotope data also suggest that a fraction of Cuatro Ciénegas groundwater originates with local recharge in mountains surrounding the bolson. Those springs that issue from the western base of the Sierra de San Marcos mountain range are recharged in part in these mountains, whereas groundwaters discharging from Laguna Anteojo in the northern part of the bolson are more likely recharged in the higher San de la Madera mountain range. An estimate of the water balance suggests that interbasin flow also may contribute to the considerable groundwater discharge.

    To systematically examine prevalence of first trimester prenatal care (FTPNC) in the 44 US counties and 80 Mexican municipios of the binational border region; and to describe disparities between border and nonborder areas within states, border states, and countries. We combined 2009 records of singleton live births from the 10 US-Mexico border states (N=1,370,206) into a single file. We included FTPNC; county/municipio, state, and country of maternal residence; and demographic variables common to all records. We computed prevalence of FTPNC for border and nonborder residents by state and country. Using multivariable regression, we computed adjusted prevalence ratios (aPR) for FTPNC in border relative to nonborder residents, states relative to one another, and the US relative to Mexico. In 2009, 68.8% of US-Mexico border mothers and 72.9% of nonborder mothers received FTPNC. After adjustment, nonborder residents had higher prevalence of FTPNC than border residents in Sonora, New Mexico, Arizona, Coahuila, and Chihuahua (aPR=1.09-124). In US states, prevalence was 13%-36% higher in New Mexico, Arizona, and California than Texas. In Mexico, when compared with Coahuila, adjusted prevalence was 12%-20% higher in neighboring states. Between countries, FTPNC prevalence in border counties/municipios was higher in Mexico among women with low parity/low education and in the United States among women with high parity/high education. In the US and Mexico, women in border counties/municipios receive less timely prenatal care than their nonborder counterparts, but the magnitude of the disparity varies by state. Lack of a consistent, binational approach to birth data collection requires cautious interpretation of findings.

    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.

    Chihuahua is Mexico's largest state, and its physiographic complexity affects the distribution of its herpetofauna. We list amphibians and reptiles for the state of Chihuahua, with their conservation status. We also compare this list to those of six adjoining states in the United States and Mexico (New Mexico, Texas, Coahuila, Durango, Sinaloa, and Sonora). A total of 175 species of amphibians and reptiles is found in Chihuahua. Thirty-eight are amphibians, and 137 reptiles. Chihuahuan amphibians and reptiles represent just over 37% of such species from Chihuahua and neighboring states. Chihuahua shares the highest proportion of its herpetofauna with Sonora and Durango. Most of the herpetofauna of Chihuahua falls in IUCNs least concern category and is not listed by SEMARNAT. However, turtles in Chihuahua are a group of particular conservation concern.

    An interferometer is composed of several radio telescopes (dishes) separated by a defined distance and used in synchrony. This kind of array produces a superior angular resolution, better than the resolution achieved by a single dish of the same combined area. In this work we propose the First Educational Youth Mexican Array North South, FEYMANS. It consists of an educational interferometer with initially four dishes. This array harvests Mexico's geography by locating each dish at the periphery of the country; creating new scientific links of provincial populations with the capital. The FEYMANS project focus in high school students and their projects on physics, chemistry and astronomy as a final project. Also, it can be used for bachelor theses. The initial and central dish-node is planed to be in Mexico City. After its construction, the efforts will focus to build subsequent nodes, on the Northwest region, Northeast, or Southeast. Region Northwest will give service to Baja California, Sonora and Chihuahua states. Region Northeast will cover Coahuila, Nuevo Leon and Tamaulipas. Finally, region Southeast will give access to Yucatan, Quintana Roo, Campeche, Tabasco and Chiapas. This project has been conceived by young professional astronomers and Mexican experts that will operate each node. Also, we have the technical support of the "Max Planck Institute fuer Radioastronomy in Bonn Germany" and the educational model of the "PARTNeR" project in Spain. This interferometer will be financed by Mexico's Federal Congress and by Mexico City's Legislative Assembly (ALDF).

    Abstract Chihuahua is Mexico’s largest state, and its physiographic complexity affects the distribution of its herpetofauna. We list amphibians and reptiles for the state of Chihuahua, with their conservation status. We also compare this list to those of six adjoining states in the United States and Mexico (New Mexico, Texas, Coahuila, Durango, Sinaloa, and Sonora). A total of 175 species of amphibians and reptiles is found in Chihuahua. Thirty-eight are amphibians, and 137 reptiles. Chihuahuan amphibians and reptiles represent just over 37% of such species from Chihuahua and neighboring states. Chihuahua shares the highest proportion of its herpetofauna with Sonora and Durango. Most of the herpetofauna of Chihuahua falls in IUCNs least concern category and is not listed by SEMARNAT. However, turtles in Chihuahua are a group of particular conservation concern. PMID:28435388

    A new species of Libellula is described from specimens collected in the most interesting area of Cuatro Ciénegas, Coahuila, México. Libellula coahuiltecana sp. nov. is similar in color and morphology to L. needhami Westfall with which it co-occurs locally. It differs from the latter by having conspicuous orange spots on base of wings and nodal area, and costal, subcostal, and wing tip areas slightly infumated with the same color. Other differences exist in the morphology of the secondary genitalia of males and the shape of the vulvar plate of female.

    Currently, the population health needs are unlimited, but allocation of financial resources is not in accordance with these needs, probably due to the lack of specific information. In this work, we propose a new approach to allocate resources with equity as a tool for decision-making in planning. The grade of equity in resource allocation in decentralized management medical areas (DMMAs (AMGD, for its initials in Spanish)) was determined; these are limited geographical areas of a social security institution in three states of the northeastern region of Mexico. The areas with more health needs in the global index were DMMA no. 12 in Tamaulipas with a Z-score (ZS) of -5; area no. 3 in Coahuila with -4; and area no. 9 in Nuevo Leon, no. 16 and no. 17 in Tamaulipas with -2. Equity was measured according to the degree of concordance between the health needs index and the per capita health expenditure of each area: (r = 0.19, P > 0.05). Low concordance was found between these variables in the studied medical areas.

    The aim of this study was to determine the contributions of stochastic vs. deterministic processes in the distribution of microbial diversity in four ponds (Pozas Azules) within a temporally stable aquatic system in the Cuatro Cienegas Basin, State of Coahuila, Mexico. A sampling strategy for sites that were geographically delimited and had low environmental variation was applied to avoid obscuring distance effects. Aquatic bacterial diversity was characterized following a culture-independent approach (16S sequencing of clone libraries). The results showed a correlation between bacterial beta diversity (1-Sorensen) and geographic distance (distance decay of similarity), which indicated the influence of stochastic processes related to dispersion in the assembly of the ponds' bacterial communities. Our findings are the first to show the influence of dispersal limitation in the prokaryotic diversity distribution of Cuatro Cienegas Basin.

    The understanding of historic hydroclimate variability is basic to determine the impact of atmospheric circulatory patterns and to plan for a proper management of limited water resources and ecosystem conservation purposes. The objective of this study was to develop a network of tree-ring chronologies for climate reconstruction and to analyze the influence of the ENSO warm phase in northern Mexico by using the Tropical Rainfall Index. Climatic sensitive tree-ring chronologies were developed in mountain ranges and riparian ecosystems of the Sierras Madre Oriental and Occidental, and central Mexico. A grid of over 30 new Douglas-fir, baldcypress, and pinyon pine chronologies were developed and seasonal winter-spring and summer precipitation reconstructions have been produced for northern and central Mexico. The seasonal winter-spring precipitation reconstructions extended 353 years (1450 - 2002) and 530 years (1472 - 2002) for Chihuahua, 228 years (1765 - 1993) and 504 years (1500 - 2003) for Durango, 602 years (1400 - 2002) for Nuevo Leon, 522 years (1474 - 1995) for Tamaulipas; and 342 years (1659 - 2001) and 410 years (1595 - 2004) for Coahuila. Some of the low frequency events were specific for each reconstruction, but common low frequency events (decadal resolution) were present in most of the reconstructions; specific cases are the droughts of the 1780s, 1810s, 1860s, 1870s, 1950s, and 1990s; and the wet episodes of the 1820s, 1830s, and 1890s.Trends in dry or wet periods were disrupted by above or below normal precipitation as affected by the ENSO phenomena, especially in the winter- spring period when this circulatory pattern produced in times abundant rains in northern Mexico. However, the ENSO influence on winter-spring precipitation has fluctuated through time. Cold fronts and hurricanes impacting the Gulf of Mexico may explain some of the hydrological behavior detected for northeastern Mexico. These results indicate that winter-spring hydroclimate

    Aedes albopictus has been known as efficient vector of dengue in Asian countries and its wide displacement of Ae. aegypti has been documented in many parts of the world. The present survey was carried out to update the distribution of Ae. albopictus in northeast Mexico and to report the first record of parasitism of mosquitoes by Ascogregarina taiwanensis in Mexico. Human landing collections were conducted in the month of May every year between 2007 and 2009 across the three states, Nuevo Leon (NL), Tamaulipas and Coahuila in northeast Mexico. Six human bait collections were also organized at the cemetery of Gomez Farias (GF), a village in southern Tamaulipas during the rainy and dry seasons in 2010. Aedes albopictus caught in 2010 were dissected for parasitic protozoan gregarines. The results of human landing collections carried out during 2007-10 across the three states of northeast zone of Mexico revealed that Ae. albopictus is invading along the route between Monterrey City in NL and Tampico, Tamaulipas, but not into the arid state of Coahuila. Aedes albopictus was recorded in nine new municipalities in addition to the 15 municipalities reported before 2005. Furthermore, six human-bait collections performed during the dry and rainy seasons in 2010 at the cemetery of GF suggest the exclusion of Ae. aegypti on that site. Dominance was shared by Ae. quadrivittatus, another container-inhabitant but indigenous species, and Ae. albopictus during the dry and rainy seasons, respectively. The results of dissection of the mosquitoes for gregarines revealed the parasitism of Ae. albopictus by A. taiwanensis. The results of this study showed that Ae. albopictus has spread to all the municipalities in the northeastern Mexico except the arid area and reported the first record of parasitic protozoan A. taiwanensis in Mexico. We recommend further studies on larval and adult populations of natural container-occupant mosquitoes in northeastern Mexico in order to have a better

    At the desert oasis of Cuatro Ciénegas in Coahuila, México, more than 300 oligotrophic pools can be found and a large number of endemic species of plants and animals. The most divergent taxa of diatoms, snail and fishes are located in the Churince hydrological system, where we analyzed the local diversification of cultivable Firmicutes and Actinobacteria. The Churince hydrological system is surrounded by gypsum dunes and has a strong gradient for salinity, temperature, pH and dissolved oxygen. In August 2003, surface water samples were taken in 10 sites along the Churince system together with the respective environmental measurements. 417 thermo-resistant bacteria were isolated and DNA was extracted to obtain their BOX-PCR fingerprints, revealing 55 different patterns. In order to identify similarities and differences in the diversity of the various sampling sites, an Ordination Analysis was applied using Principal Component Analysis. This analysis showed that conductivity is the environmental factor that explains the distribution of most of the microbial diversity. Phylogenetic reconstruction from their 16S rRNA sequences was performed for a sample of 150 isolates. Only 17 sequences had a 100% match in the Gene Bank (NCBI), representing 10 well known cosmopolitan taxa. The rest of the sequences cluster in 22 clades for Firmicutes and another 22 clades for Actinobacteria, supporting the idea of high diversity and differentiation for this site.

    One of the most important marine sequences of calcareous rocks from the Paleozoic of Mexico outcrops in southern Chiapas. It is composed by different units from Early Permian, being the Paso Hondo Formation the youngest with a Leonardian age. Different groups of marine invertebrates as corals, bivalves, gastropods, bryozoans, brachiopods and crinoids have been previously reported of this unit. Five brachiopod species of the orders Productida, Athyridida, Spiriferida and Spiriferinida from the Barrio Allende section of this unit are herein described. The new species Dyoros (Lissosia) maya and Hustedia shumardi are proposed. Sedimentology and paleoecology of the Paso Hondo Formation, suggest a well-lighted shallow lagoon environment with continuous terrigenous input. The subgenus Dyoros (Lissosia), the genus Paucispinifera and the species Hustedia shumardi, Spiriferella propria and Spiriferellina tricosa are typical taxa from Permian localities of Texas, New Mexico and Coahuila. Their presence in the studied area suggests that during Early Permian there was a geographic connection between the different localities of the biotic Grandian Province (southern USA, northern Mexico and Venezuela) and southeastern Chiapas.

    To identify the presence and frequency of various predispose factors of breast cancer in the Region Lagunera (Mexico). 38 women with breast cancer (Group A, cases) and 24 women without breast pathology (Group B, controls) were analyzed; throughout a questionnaire the variables that have been described as predisposition factors were researched. Group A included patients from the Instituto Mexicano del Seguro Social, Speciality Hospital # 71, Oncology Department in Torreon, Coahuila, from May 1st to October 31st of 1999. At the same time 24 women (Group B), who attended to have an ultrasound and/or a mammography practice in a private clinic in the same city, were polled having a normal result. The means of the two treatments were compared using the SAS program version 6.3. The following variables showed significant difference: mother and father family background with cancer p=0.032; previous breast pathology p=0.0032; hormone consumption p=0.0289; lactation p=0.038 and time of lactation p=0.036. Overweight, obesity, mother and father family background with cancer, previous breast pathology background, period of consuming hormone, lactation and lactation period had significance in this study.

    Inorganic arsenic exposure in drinking water has been recently related to diabetes mellitus. To evaluate this relationship the authors conducted in 2003, a case-control study in an arseniasis-endemic region from Coahuila, a northern state of Mexico with a high incidence of diabetes. The present analysis includes 200 cases and 200 controls. Cases were obtained from a previous cross-sectional study conducted in that region. Diagnosis of diabetes was established following the American Diabetes Association criteria, with two fasting glucose values > or = 126 mg/100 ml (> or = 7.0 mmol/l) or a history of diabetes treated with insulin or oral hypoglycemic agents. The next subject studied, subsequent to the identification of a case in the cross-sectional study was taken as control. Inorganic arsenic exposure was measured through total arsenic concentrations in urine, measured by hydride-generation atomic absorption spectrophotometry. Subjects with intermediate total arsenic concentration in urine (63.5-104 microg/g creatinine) had two-fold higher risk of having diabetes (odds ratio=2.16; 95% confidence interval: 1.23, 3.79), but the risk was almost three times greater in subjects with higher concentrations of total arsenic in urine (odds ratio=2.84; 95% confidence interval: 1.64, 4.92). This data provides additional evidence that inorganic arsenic exposure may be diabetogenic.

    This review focuses on the occurrence and treatment of arsenic (As) in the arid region of northern Mexico (states of Chihuahua and Coahuila) and bordering states of the southwestern US (New Mexico, Arizona, and Texas), an area known for having high As concentrations. Information assembled and assessed includes the content and probable source of As in water, soil, and sediments and treatment methods that have been applied in the area. High As concentrations were found mainly in groundwater, their source being mostly from natural origin related to volcanic processes with significant anthropogenic contributions near mining and smelting of ores containing arsenic. The affinity of As for solid phases in alkaline conditions common to arid areas precludes it from being present in surface waters, accumulating instead in sediments and shifting its threat to its potential remobilization in reservoir sediments and irrigation waterways. Factors such as oxidation and pH that affect the mobility of As in the subsurface environment are mentioned. Independent of socio-demographic variables, nutritional status, and levels of blood lead, cognitive development in children is being affected when exposed to As. Treatments known to effectively reduce As content to safe drinking water levels as well as those that are capable of reducing As content in soils are discussed. Besides conventional methods, emergent technologies, such as phytoremediation, offer a viable solution to As contamination in drinking water.

    We present general comments on the epidemiology of measles considering the pre-vaccine era as well as the post-vaccine period in which some changes can be observed: the decrease in morbidity and mortality, the extension of the inter-epidemic interval, the increase in the mean age of infection, etc. We make some estimations about the vaccine coverage and the ideal age of immunization for the goal of eradication (assuming a lifelong immunity for the vaccinees). The technical problems in measles immunization are also revised explaining why no continental country has been able to eliminate the disease. We describe the epidemiological situation in North America, Mexico and Latin American countries. Lastly we present the Mexican experience with the inhaled aerosolised vaccine: the studies in Monterrey (Sabin et al, 1982), other investigation in Mexico, D.F. and in the State of Jalisco, as well as the mass campaigns in Aguascalientes in 1988 and in Coahuila and Nuevo León in 1989. We propose it as an effective, harmless, simple, inexpensive and practical method.

    New decapod specimens from mid-Paleocene shallow marine deposits of NE Mexico represents an important addition to the diversity, paleobiogeography and evolution of the Crustacea record. In this work, we describe additions to the decapod assemblage from the Paleocene (Selandian) Rancho Nuevo Formation (Difunta Group, Parras Basin, Coahuila). Due to the evident size differences with other decapod assemblages, we compare the new assemblage with those from the Lower Paleocene (Danian) Mexia Clay Member of the Wills Point Formation, Texas, and the Lower Eocene (Ypresian) El Bosque Formation in Chiapas. Species reported from the mid-Paleocene (Selandian) assemblage of the Porters Creek Formation (Alabama), are correlatable to the decapod species from NE Mexico in age, size and systematic composition. The erymid lobster Enoploclytia gardnerae (Rathbun, 1935) is represented by several carapaces and chelae remains. One isolated palm of Callianassidae is included. Numerous carapaces of Linuparus wilcoxensis Rathbun, 1935 are described, representing the most abundant lobster. A new record for the raninid Notopoides sp., and presence of Quasilaeviranina sp. cf. arzignagnensis and Quasilaeviranina ovalis are here reported. New raninids, Claudioranina latacantha sp. nov. and Claudioranina sp. (Cyrtorhininae) are also part of this assemblage. Paraverrucoides alabamensis (Rathbun, 1935), and Tehuacana americana (Rathbun, 1935) are represented by several carapaces exhibiting intraspecific morphological variation. Different sizes among the Early and Middle Paleocene and Early Eocene decapod populations suggests a possible effect of variation in seawater temperatures and/or a Lilliput effect after the K/Pg event.

    Northeastern Mexico hosts numerous epigenetic stratabound carbonate-hosted low-temperature hydrothermal deposits of celestine, fluorite, barite and zinc-lead, which formed by replacement of Mesozoic evaporites or carbonate rocks. Such deposits can be permissively catalogued as Mississippi Valley-type (MVT) deposits. The deposits studied in the state of Coahuila are associated with granitic and metasedimentary basement highs (horsts) marginal or central to the Mesozoic Sabinas Basin. These horsts controlled the stratigraphy of the Mesozoic basins and subsequently influenced the Laramide structural pattern. The Sabinas Basin consists of ~6,000-m-thick Jurassic to Cretaceous siliciclastic, carbonate and evaporitic series. The MVT deposits are mostly in Barremian and in Aptian-Albian to Cenomanian formations and likely formed from basinal brines that were mobilized during the Laramide orogeny, although earlier diagenetic replacement of evaporite layers (barite and celestine deposits) and lining of paleokarstic cavities in reef carbonates (Zn-Pb deposits) is observed. Fluid inclusion microthermometry and isotopic studies suggest ore formation due to mixing of basinal brines and meteoric water. Homogenization temperatures of fluid inclusions range from 45°C to 210°C; salinities range from 0 to 26 wt.% NaCl equiv., and some inclusions contain hydrocarbons or bitumen. Sulfur isotope data suggest that most of the sulfur in barite and celestine is derived from Barremian to Cenomanian evaporites. Regional geology and a compilation of metallogenic features define the new MVT province of northeastern Mexico, which comprises most of the state of Coahuila and portions of the neighboring states of Nuevo León, Durango and, perhaps extends into Zacatecas and southern Texas. This province exhibits a regional metal zonation, with celestine deposits to the south, fluorite deposits to the north and barite and Zn-Pb deposits mostly in the central part.

    Abstract A revision and key to the 23 species and eight subspecies of Poa (including Dissanthelium) known to occur in Mexico is provided. All voucher specimens seen are cited for accepted taxa, except Poa annua for which one voucher per state is provided. Taxa not previously known from, or poorly understood in, Mexico are discussed.Poa palmeri sp. nov. is endemic to forested slopes of the Sierra Madre Oriental, and we distinguished it from Poa ruprechtii s.s., a species of central Mexico that is here emended to include Poa sharpii (syn. nov.). Poa wendtii sp. nov. is described from the Sierra Santa Rosa in northern Coahuila. Poa tacanae is placed in synonymy in Poa seleri. Poa gymnantha and Poa occidentalis are newly reported for Mexico, and material historically identified as Poa villaroelii areplaced in Poa chamaeclinos.The genus Dissanthelium is considered to belong within Poa, and the Mexican taxa, Dissanthelium calycina subsp. mathewsii and Dissanthelium californicum, are treated as Poa calycina var. mathewsii and Poa thomasii, respectively. Poa subsect. Papillopoa subsect. nov. is erected for Poa mulleri. Lectotypes are designated for Poa conglomerata and Poa seleri. PMID:23185125

    The tick-borne pathogens Ehrlichia canis and Anaplasma platys are the causative agents of canine monocytic ehrlichiosis (CME) and canine cyclic thrombocytopenia (CCT). Although molecular evidence of E. canis has been shown, phylogenetic analysis of this pathogen has not been performed and A. platys has not been identified in Mexico, where the tick vector Rhipicephalus sanguineus sensu lato (s.l.) is common. The aim of this research was to screen, identify and characterize E. canis and A. platys by PCR and phylogenetic analysis in dogs from La Comarca Lagunera, a region formed by three municipalities, Torreon, Gomez-Palacio and Lerdo, in the Northern states of Coahuila and Durango, Mexico. Blood samples and five engorged R. sanguineus s.l. ticks per animal were collected from 43 females and 57 male dogs presented to veterinary clinics or lived in the dog shelter from La Comarca Lagunera. All the sampled dogs were apparently healthy and PCR for Anaplasma 16S rRNA, Ehrlichia 16S rRNA, and E. canis trp36 were performed. PCR products were sequenced and used for phylogenetic analysis. PCR products were successfully amplified in 31% of the samples using primers for Anaplasma 16S rRNA, while 10% and 4% amplified products using primers for Ehrlichia 16S rRNA and E. canis trp36 respectively. Subsequent sequencing and phylogenetic analyses of these products showed that three samples corresponded to A. platys and four to E. canis. Based on the analysis of trp36 we confirmed that the E. canis strains isolated from Mexico belong to a conservative clade of E. canis and are closely related to strains from USA. In conclusion, this is the first molecular identification of A. platys and the first molecular characterization and phylogenetic study of both A. platys and E. canis in dogs in Mexico.

    The High Altitude Water Cerenkov detector HAWC will be a powefull instrument to survey the TeV sky. Mexico has proposed to locate this experiment in the Parque Nacional Pico de Orizaba, between Citlaltepetl and Tliltepetl, host of the Large Millimeter Telescope (LMT). The region has a sizeable technical infrastructure related to the LMT and we recently studied a 4100m location in terms of its feasibility to host HAWC. We present the proposed site location and extension, its water acquisition, experimental and complementary infrastructures.

    The objective of this study was to determine the seroprevalence of Toxoplasma gondii and Neospora caninum in white-tailed deer from Northern Mexico. Sera from 532 white-tailed deer (Odocoileus virginianus) from three Northern states of Mexico were assayed for antibodies to T. gondii by ELISA and western blot. From these samples, 368 were available to test for N. caninum antibodies by ELISA. The overall prevalence for T. gondii antibodies was 13.9% (74/532; CI(95) 11-17) and for N. caninum 8.4% (31/368; CI(95) 6-12). There was a significant association between positive ELISA results for T. gondii, with management factors within ranches, such number of deer per hectare and geographic location of deer, but none for N. caninum. T. gondii infection in the deer from Guerrero, Coahuila had an increased risk than those from Nuevo Laredo, Tamaulipas (OR, 8.3; CI(95) 1.9-35.4; P<0.05) and ranches with one deer in 15 ha had increased risk of positive association (OR, 2.61; CI(95) 1.5-4.4; P<0.05). These findings may have environmental or public health implications because venison can be an important meat source of T. gondii infections for humans and feral cats.

    An inventory of air pollutants emitted from forest and agricultural fires in Northeastern Mexico for the period of January to August of 2000 is presented. The emissions estimates were calculated using an emissions factor methodology. The inventory accounts for the emission of carbon monoxide (CO), methane, nonmethane hydrocarbons, ammonia, nitrogen oxides, and particulate matter (PM). Particulate matter emissions include estimates for fine PM and coarse PM. A total of 2479 wildfires were identified in the domain for the period of interest, which represented approximately 810,000 acres burned and 621,130 short tons emitted (81% being CO). The main source of information used to locate and estimate the extent of the fires came from satellite imagery. A geographic information system was used to determine the type of vegetation burned by each fire. More than 54% of the total area burned during the period of study was land on the State of Tamaulipas. However, >58% of the estimated emissions came from the State of Coahuila. This was because of the mix of vegetation types burned in each state. With respect to the temporal distribution, 76.9% of the fires occurred during the months of April and May consuming almost 78% of the total area burned during the period of study. Analysis of wind forward trajectories of air masses passing through the burned areas and 850-mb wind reanalyses indicate possible transboundary transport of the emissions from Mexico to the United States during the occurrence of the major wildfires identified.

    10 socialworkers were recruited to identify and interview nonmedical abortion providers and clients in the northern Mexico states of Sonora, Tamaulipas, Chihuahua, Nuevo Leon, Coahuila, and Baja California for a 1979 study. Problems were encountered with wording of the questionnaire and the quality of the work of some of the social workers. 49 single clients aged 24.5 years on average and 29 married clients aged 29 years on average were interviewed. The married women appeared to be of slightly lower educational and social status than the single. Single women paid on average U. S. $91, $37 more than married women, but otained better service and had lower rates of complication. 65% of married women attempted to induced menstruation themselves before seeking abortions. Only 2 women, both married, waited more than 3 months to seek abortions, both because of lack of funds. Little relation was found between the cost, method, and quality of the abortions. Married women sought abortions typically for economic reasons, while single women did so for social reasons. The 11 female and 1 male nonmedical abortion providers were aged 32 to 53 years, 2 were nurses, and the rest had 6 or fewer years of education. 1 nurse performed D and Cs with local anesthesia, 7 used probes, 3 used herbal injections and 1 used an infusion of herbs. 5 had learned their techniques from medical personnel. Income from abortions was the major source of livelihood for 10 of the 12 but charges, volume of patients, and total income varied. The average provider had been performing abortions for over 10 years.

    Ecological succession is one of the most important concepts in ecology. However for microbial community succession, there is a lack of a solid theoretical framework regarding succession in microorganisms. This is in part due to microbial community complexity and plasticity but also because little is known about temporal patterns of microbial community shifts in different kinds of ecosystems, including arid soils. The Cuatro Cienegas Basin (CCB) in Coahuila, Mexico, is an arid zone with high diversity and endemisms that has recently been threatened by aquifer overexploitation. The gypsum-based soil system of the CCB is one of the most oligotrophic places in the world. We undertook a comparative 16S rRNA 454 pyrosequencing study to evaluate microbial community succession and recovery over a year after disturbance at two sites. Results were related to concurrent measurements of humidity, organic matter and total C and N content. While each site differed in both biogeochemistry and biodiversity, both present similar pattern of change at the beginning of the succession that diverged in later stages. After one year, experimentally disturbed soil was not similar to established and undisturbed adjacent soil communities indicating recovery and succession in disturbed soils is a long process.

  6. Stratigraphy, geochronology, geochemistry and tectonic setting of the Mesozoic Nazas Formation, north-central Mexico

    NASA Astrophysics Data System (ADS)

    Bartolini, Claudio

    Late Triassic to Middle Jurassic volcanic-sedimentary sequences that were part of the Mesozoic continental-margin of western North America are exposed in northern and central Mexico. These sequences have been grouped into the Nazas Formation and crop out in the states of Durango, Coahuila, Zacatecas, and San Luis Potosi. The Nazas Formation consists of 2,500 m or more of volcanic and pyroclastic rocks and interbedded clastic sedimentary rocks that were deposited in alluvial fan and fluvial depositional systems that developed in intra-arc basins, mainly fault-bound grabens and topographic depressions within an extending Mesozoic volcanic arc. Major and trace element geochemistry of volcanic rocks suggests that the volcanic suite is calc-alkaline and includes rhyolite, dacite, rhyodacite, andesite, trachyandesite and rare basalt. Pyroclastic rocks are basically air-fall tuffs and volcanic breccias. The sedimentary strata include conglomerate, sandstone, shale, and siltstone, locally red in color. Geochronology (Ar-Ar, K-Ar and Rb-Sr) and field evidence indicate that the age of the Nazas Formation ranges from Late Triassic to Middle Jurassic, but the peak of arc volcanism appears to be Early and Middle Jurassic. The Mesozoic magmatic arc in Mexico has a northwest trend and extends from Sonora to Chiapas. The arc structure is more than 2,000 km long, and possibly up to 150 km wide. The width of the arc is uncertain due to the limited number of surface outcrops, however, it did not extend east into the Gulf of Mexico. Arc-related magmatism began in latest Triassic time, but the peak of arc evolution occurred during the Early and Middle Jurassic. By Oxfordian time, the arc was deeply dissected and eroded, and magmatic activity had ceased. A marine transgression from the Gulf of Mexico covered most of the Nazas arc, depositing the initial sediments of the Oxfordian Zuloaga Limestone in the Mexican Geosyncline. Jurassic crustal extension in the Gulf of Mexico was

  12. Soil-geomorphology and “wet” cycles in the Holocene record of North-Central Mexico

    The distinction between the impact of climatic periodicities or land-use practices on soil erosion is an important issue for Pre-Hispanic and Colonial Mexico. That question can best be addressed by first documenting the dynamics of changing "wet" cycles during the Holocene in the central Mexican region between the northern limits of Pre-Hispanic agriculture and its southern margins in northwestern Chihuahua. Consequently the Laguna Project targeted a 125,000 km 2 sector of North-Central Mexico, 250 km from north to south and 500 km from east to west, from Saltillo to Durango. Some 40 sedimentary profiles with multiple cumulic soils were studied in the field and laboratory, supported by 163 conventional 14C and AMS dates on charcoal and soil humates. We distinguish: (1) wet floodplains (with humic paleosols, redox phenomena reflecting high water tables, channel-ponding sequences, and interbedded tufas) that imply aquifer recharge, sustained base flow, and mainly low-energy conditions; and (2) high-energy pulses of discharge that mobilized cobble gravels or forced channel entrenchment ("gullying") and were tied to episodic, excessive rains that promoted valley and slope instability. In between such "wet" cycles and recurrent disequilibrium events, climate was similar to today, probably less humid, with limited geomorphologic change or slow soil formation. "Wet" cycles were rare at the end of the Pleistocene, but prominent during the Holocene. Disequilibrium proxies became common and dramatic after 2500 BP. The drainages from the Eastern and Western Sierra Madres responded in phase, but varied in detail. Around AD 1050-1200 "natural" erosion led to loss of soil organic carbon, as alternating severe droughts and heavy rains destroyed the ground cover and led to ecological aridification, well before arrival of Spanish miners and settlers. The evidence that human activity triggered Pre-Hispanic or Colonial erosion in Central Mexico should therefore be re

    Statistical data available on the 19th century Mexican population are for the most part scarce, of doubtful reliability, and dispersed. The war of independence, civil wars, regional conflicts and foreign interventions affected demographic behavior and also hampered implementation of a national census. The 3 types of available data on the 19th century population include a few state censuses, some censuses conducted by individuals, and data from civil registration and parish records. This work examines general development of Mexico's population in the 19th century, regional distribution, and political divisions. Mexico's population is estimated to have increased from 6,837,100 in 1803 to 10,448,000 in 1884, figures indicating a slow rate of growth. The relatively slow growth is probably explained by higher mortality rates not compensated by the high fertility. Mortality began to decline around 1850, and overall growth rates increased towards the end of the century. Epidemics, pandemics, poor harvests, droughts, and civil wars all contributed to the high rates. Colonial and prehispanic patterns of population distribution remained almost unchanged until midcentury, when a significant movement toward the north began to occur. Available sources do not permit division of Mexico into regions based on socioeconomic data or on economic structures. Juridicopolitical divisions offer useful approximations for regional analysis of population trends. Among 5 resulting regions, the North Pacific contained slightly over 3% of the population and was largely isolated from the rest of Mexico. The North, including Sonora, Chihuahua, Coahuila, Durango, Nuevo Leon and Zacatecas, contained around 9%. Taken as a whole, the population of the North region did not change much, but individual areas such as Sonora lost population while Nuevo Leon had an annual growth rate averaging 1.65%. The Caribbean Coast overall lost population despite some areas of growth. The share declined from 19.4% in

    Transboundary zoonotic diseases, several of which are vector borne, can maintain a dynamic focus and have pathogens circulating in geographic regions encircling multiple geopolitical boundaries. Global change is intensifying transboundary problems, including the spatial variation of the risk and incidence of zoonotic diseases. The complexity of these challenges can be greater in areas where rivers delineate international boundaries and encompass transitions between ecozones. The Rio Grande serves as a natural border between the US State of Texas and the Mexican States of Chihuahua, Coahuila, Nuevo León, and Tamaulipas. Not only do millions of people live in this transboundary region, but also a substantial amount of goods and people pass through it everyday. Moreover, it occurs over a region that functions as a corridor for animal migrations, and thus links the Neotropic and Nearctic biogeographic zones, with the latter being a known foci of zoonotic diseases. However, the pathogenic landscape of important zoonotic diseases in the south Texas-Mexico transboundary region remains to be fully understood. An international perspective on the interplay between disease systems, ecosystem processes, land use, and human behaviors is applied here to analyze landscape and spatial features of Venezuelan equine encephalitis, Hantavirus disease, Lyme Borreliosis, Leptospirosis, Bartonellosis, Chagas disease, human Babesiosis, and Leishmaniasis. Surveillance systems following the One Health approach with a regional perspective will help identifying opportunities to mitigate the health burden of those diseases on human and animal populations. It is proposed that the Mexico-US border along the Rio Grande region be viewed as a continuum landscape where zoonotic pathogens circulate regardless of national borders.

    Northeast Mexico is essentially the juncture of two distinctly different tectono-stratigraphic provinces, the eastern Gulf of Mexico (Coastal Plane, Sierra Madre Oriental) province and the western Pacific Mexico (Rivera plate, Meso-American trench, Sierra Madre Occidental) province (Goldhammer & Johnson, 2001). Tectonic evolution in northeast Mexico is dominated by divergent-margin development associated with the opening of the Gulf of Mexico and overprinted by non-igneous Laramide orogenic effects (Pindell et al., 1988). The structural grain of northeast Mexico consists of Triassic to Liassic fault-controlled basement blocks, the development of which reflects in part late Paleozoic orogenic patterns of metamorphism and igneous intrusion (Wilson, 1990). There are different tectonic provinces which are recognized interpreting the basement and sediment cover of this area: Coahuila block, La Popa sub-basin, Sabinas basin, Burgos basin, Sierra Madre Oriental (Monterrey trough), and Parras basin. Mojave-Sonora megashear and San Marcos fault (Chavez-Cabello et al., 2007) are two principal fault zones crossing the northeast Mexico in NW-SE direction. This paper is presented the integral analysis of the gravity and magnetic data in the northeast Mexico. Complementing with a Digital Model of Elevations (DME) that combined with the review of previous geological studies it serves to compare the surface structures and blocks of basement in this area. Also the separation of the most important tectonic blocks was done, and 2.5D geological-geophysical model was finally developed. This model represents in a general way the principal structural characteristics of northeast Mexico. Gravity and magnetic data analysis was used with purpose to study the structure of the substrata in order to allow modeling of the basement structure and its relation with the sedimentary cover features. The Bouguer gravity and the total field aeromagnetic data were supplied by Geological Survey of Mexico

    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.

    The OMEGA/Mars Express hyperspectral imager identified gypsum at several sites on Mars in 2005. These minerals constitute a direct record of past aqueous activity and are important with regard to the search of extraterrestrial life. Gale Crater was chosen as Mars Science Laboratory Curiosity's landing site because it is rich in gypsum, as are some desert soils of the Cuatro Ciénegas Basin (CCB) (Chihuahuan Desert, Mexico). The gypsum of the CCB, which is overlain by minimal carbonate deposits, was the product of magmatic activity that occurred under the Tethys Sea. To examine this Mars analogue, we retrieved gypsum-rich soil samples from two contrasting sites with different humidity in the CCB. To characterize the site, we obtained nutrient data and analyzed the genes related to the N cycle (nifH, nirS, and nirK) and the bacterial community composition by using 16S rRNA clone libraries. As expected, the soil content for almost all measured forms of carbon, nitrogen, and phosphorus were higher at the more humid site than at the drier site. What was unexpected is the presence of a rich and divergent community at both sites, with higher taxonomic diversity at the humid site and almost no taxonomic overlap. Our results suggest that the gypsum-rich soils of the CCB host a unique microbial ecosystem that includes novel microbial assemblies.

    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.

The measurements document a remarkably consistent west-east to northwest-southeast direction of the contemporary least horizontal stress in the upper crust of this intraplate region. In the regional neotectonic framework, the data suggest that Mexico north of the trans-Mexican volcanic belt is being stretched in west-east to northwest-southeast direction. The measurements from the area of the Laramide Chihuahua and Coahuila fold-thrust belts define the southern extend of the Basin and Range—Rio Grande rift stress province of the southwestern United States into northern Mexico. The least horizontal in situ stress directions recorded in the Gulf Coastal Plain (Burgos and Tampico-Misantla Basins) are oblique to the continental margin of the Gulf of Mexico, but subparallel to the direction measured in the area of the Basin and Range—Rio Grande rift stress province. This suggests that the stress distribution in these basins is not mainly the result of gravitational loading as in the Gulf Coast stress province of the United States, but is controlled by the same lithospheric stress system that characterizes the Basin and Range—Rio Grande rift stress province. This is also supported by the north-south trending zone of Oligocene-Quaternary alkaline volcanism that crosses the Tampico-Misantla Basin. Furthermore, the data indicate that the active deformation of the Mexican Ridges fold belt, east of the study area in the Gulf of Mexico cannot be caused by a compressional external tectonic load. The direction of the least horizontal in situ stress measured in the area of the Laramide Sierra Madre Oriental fold-thrust belt in Hidalgo and San Luis Potosí States is consistent with that of the other zones. However, wellbore elongations were recorded less frequently and show a rather large circular variance, which suggests that

    Abstract The OMEGA/Mars Express hyperspectral imager identified gypsum at several sites on Mars in 2005. These minerals constitute a direct record of past aqueous activity and are important with regard to the search of extraterrestrial life. Gale Crater was chosen as Mars Science Laboratory Curiosity's landing site because it is rich in gypsum, as are some desert soils of the Cuatro Ciénegas Basin (CCB) (Chihuahuan Desert, Mexico). The gypsum of the CCB, which is overlain by minimal carbonate deposits, was the product of magmatic activity that occurred under the Tethys Sea. To examine this Mars analogue, we retrieved gypsum-rich soil samples from two contrasting sites with different humidity in the CCB. To characterize the site, we obtained nutrient data and analyzed the genes related to the N cycle (nifH, nirS, and nirK) and the bacterial community composition by using 16S rRNA clone libraries. As expected, the soil content for almost all measured forms of carbon, nitrogen, and phosphorus were higher at the more humid site than at the drier site. What was unexpected is the presence of a rich and divergent community at both sites, with higher taxonomic diversity at the humid site and almost no taxonomic overlap. Our results suggest that the gypsum-rich soils of the CCB host a unique microbial ecosystem that includes novel microbial assemblies.

    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.

    Structural analysis of outcrop and anisotropy of magnetic susceptibility (AMS) data from the Sierra del Fraile anticlinorium (25°80'N / 100°30'W), Coahuila Marginal Folded Province, northeast Mexico, elucidates complex fold kinematics in an orogenic foreland. Sierra del Fraile is a regional-scale décollement fold, with a ~4.5 km clastic and carbonate section deformed above a ~3 km thick evaporite unit. Mesoscopic structures, including extensional (joints and veins) and shear fractures, stylolites, and cleavage, were measured in diverse lithologies in both limb and hinge positions to constrain fold kinematics. These mesoscopic structures were also used to validate the use of AMS as a proxy for penetrative tectonic strain orientations. AMS was determined on oriented samples from limb and hinge positions in multiple facies in the thin-bedded shales of the La Casita, La Peña, and Cuesta del Cura Fms., and the thick-bedded carbonates of the Cupido and Taraises Fms. In this study, only the orientation of the AMS fabric ellipsoid is considered, since the magnitude of magnetic susceptibility varied between carbonate facies from the same structural position. In general, strain geometry as determined by mesoscopic structural analysis agreed with that determined by AMS. In combination, the mesoscopic structures and AMS geometries record a strain history of diagenetic compaction followed by early layer-parallel shortening, then progressive limb rotation and hingeward shear about pinned anticlinal and synclinal hinges with constant limb length and a mobile décollement and finally late fold flattening. This study shows that AMS is a sensitive proxy for nascent penetrative strain orientations in clastic and carbonate sedimentary rocks.

    Human footprints provide a direct record of human occupation and can be used to make a range of biometric inferences about the individuals which left them. In this paper we describe the application of three-dimensional optical laser scanning in the preservation and analysis both human and animal footprints. Optical laser scanning provides a digital elevation model of a print or surface with a vertical accuracy typically less than + 0.01 mm. Not only does this provide a procedure for recording fragile footprint evidence but allows digital measurements to be made. It is also possible to use the techniques developed for rapid proto-typing to recreate the print as solid models for visualisation. The role of optical laser scanning in the preservation of footprint evidence is explored with specific reference to the controversial footprints of the Valsequillo Basin in Central Mexico which may provide some of the earliest evidence of human colonization of the Americas. More importantly, digital footprint scans provide a basis for the numerical analysis of footprints allowing the tools of geometric morphometrics to be applied. These tools have been widely developed in the fields of biology and physical anthropology and used to explore the anatomical significance of shape. One key question that can be addressed using this approach is to develop a statistical approach to the objective recognition of a human footprint thereby helping to verify their interpretation and archaeological significance. Using footprint data from sites across the World a statistical model for the recognition of human footprints is presented and used to evaluate the controversial footprint site of Valsequillo, (Puebla State) preserved in volcanic ash and those in the Cuatrocienegas Basin, (Coahuila State) preserved in travertine.

    The object of paper has been the study of amebic seroepidemiology in the northern region of Mexico, by means of an immunoenzymatic assay in solid phase (ELISA). The proteic antigen was obtained from axenic culture of E. histolytica's trophozoites of strain HM1:IMSS, by means of solubilization with phenoxy polyethoxyethanol (Triton X-100). Standardization of the method was obtained by analysis of 80 sera from patients with both a clinical and radiologic diagnosis of amebic hepatic abscess and 80 sera from healthy patients. The sensitivity reached 95% and the specificity was 90.7%. 15,457 sera from eight Mexican northern states were tested as part of the National Seroepidemiologic Survey. A semiautomatic BIOMEK 1,000 (Beckman Ins.) equipment was used. The positive ratio varied between 2.0% in Southern Baja California and 4.92% in Chihuahua, with an average ratio for the whole group of 3.34%. The first three places, in descending order, are Chihuahua (4.92%), Sinaloa (4.01%) and Northern Baja California (3.78%). The positive man: woman ratio was 0.87:1 and fluctuated between 0.38:1 in Coahuila and 1.76:1 in Nuevo Leon. In the whole sample the positive ratio of men was 3.00% and in women was 3.43%. The antibody profile related to age, is similar to diseases reported to be highly endemic; the percentage of positive sera rose progressively up to the age of 20 years (4.05%), at which a plateau occurred with a slight descending tendency up to 60 years of age (3.54%), after which a clear descent in the positive index is seen. No important variations were observed when comparing groups of ages and sexes. The antibody level seems to show an inverse relationship with the incidence rate of amebiasis.

    Autoimmune hepatitis (AIH) is a chronic inflammatory disease of the liver with nonspecific clinical manifestations that causes greater liver damage in children than in adults. To analyze the clinical progression, biochemical profiles, histopathologic changes, and treatment response in 20 children with AIH. A retrospective study was carried out on the variables associated with clinical progression, diagnosis, and treatment response in children seen at the the Unidad Médica de Alta Especialidad (UMAE) No. 71 IMSS in Torreón, Coahuila, Mexico, from 1992 to 2012. Twenty patients were analyzed, 75% with type 1 AIH (AIH-1) and 25% with type 2 AIH (AIH-2). Girls predominated with a 3:1 ratio of girls to boys. The mean age was 10.07 ± 6.53 years for the AIH-1 cases and 6.75 ± 3.77 years for the AIH-2 cases. There was an association with immunologic diseases in 40% of the patients. The patients in the AIH-2 group had greater biochemical profile alterations and IgA deficiency. Anti-nuclear antibody and anti-smooth muscle antibody were positive in 100% of the patients with AIH-1, and anti-liver kidney microsomal type 1 antibody was positive in 100% of the AIH-2 patients. Liver biopsy revealed interface hepatitis in both groups. The AIH-2 group responded more quickly to treatment, but had a higher recurrence rate. Autoimmune hepatitis in the pediatric patient should be suspected in order to make an early diagnosis and thereby establish opportune treatment. Determining the type of AIH is necessary for making adequate diagnosis and for achieving a better outcome in relation to recurrence and complication rates.

    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.

    Drought is a phenomenon that has intensified during the last few decades in the arid and semi-arid zones of northern Mexico. In the Chihuahua desert, across Chihuahua, Durango and Coahuila states has caused loss of food sustainability (agriculture, livestock), an increase in human health problems, and detriment of ecosystem services as well as important economic losses. In order to understand this phenomenon, it is necessary to create tools that allow monitoring the territory's spatial heterogeneity and multi-temporality. With this purpose we propose the implementation of a drought model which includes the traditional indexes of climatic drought, such as the Palmer Drought Severity Index PDSI, the Standardized Index of Rainfall SPI, data from meteorological stations and biophysical variations obtained from the MODIS sensors product MOD13 NDVI from 2001 to 2010, as well as biophysical variables characteristic of the environment, such as land use and vegetation coverage, Eco-regions, soil moisture, digital elevation model and irrigate agriculture districts. With the MODIS images, a spatially coherent time series was created analyzing the study area's phenology (TIMESAT) created the Seasonal Greenness (SG) and Start of Season Anomaly (SOSA) for the mentioned nine years. Through this, the annual cycles were established. With a decision tree model, all the previously mentioned proposed variables were integrated. The proposed model produces a general map which characterizes the vegetation condition (extreme drought, severe drought, moderate drought, near normal). Even though different techniques have been proposed on the monitoring of droughts, most of them generate drought indexes with a spatial resolution of 1km (Wardlow, B. et. al 2008; Levent T. et al. 2013). One of the main concerns of researchers on the matter is on improving the spatial information content and on having a better representation of the phenomenon. We use the normalized difference vegetation index

  5. Groundwater Recharge Evaluation in Semi-Arid Northeast Mexico in Response to Projected Climate Change

    2007-12-01

    This research evaluates the effects of projected climate change on mountain recharge in the semi-arid Cuatrocinegas Basin (CCB) of northeast Mexico. The CCB UNESCO Biosphere Reserve is located in Coahuila, Mexico (~27° N, ~102° W) and includes > 500 springs that discharge from a regional flow system to wetlands with > 70 endemic species and to an irrigation network. This study tests the hypothesis that projected climate changes will reduce CCB recharge. In CCB, ~75% of annual precipitation (~220 mm at 700 m, ~400 mm at 2350 m) falls between May and October and ~40% falls during the North American Monsoon in June, July, and August. Environmental isotopes indicate aquifer residence times of > 50 years. Stable isotopes (O and H) show that mountain precipitation (at an elevation of ~1170 to 2350 m) dominates groundwater recharge. Recharge is insignificant at lower- elevation valleys that cover the majority of the study area due to high evapotranspiration rates. A Cl--balance water-budget recharge analysis estimates a spatially distributed recharge rate of ~1 to 3% of precipitation to provide at least 35x106 m3/year spring discharge (as measured in canals that drain dozens of springs). IPCC AR4 climate projections predict an annual temperature increase of 3.0 to 3.5°C and an annual precipitation decrease of 5 to 10% for Subregion CNA (located adjacent to CCB) by 2099. During June to August, models project a temperature increase of 3.5 to 4.0°C and a precipitation increase of 0 to 5%. Although global and regional circulation models evaluate mountain regions poorly, a first-order evaluation of climate projections on CCB recharge is needed input to develop effective long-term groundwater management policies. Climate projections suggest that the minimum elevation at which recharge occurs in CCB may increase by ~615 m to 1785 m, which would limit recharge to the highest mountain elevations. If annual precipitation is reduced by 5 to 10% and temperatures increase as

    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.

    A study was conducted in 2006 to determine the prevalence of Salmonella on three cantaloupe farms in Matamoros, Coahuila, Mexico, and on one farm that cultivates chile peppers var. Bell in Culiacán, Sinaloa, Mexico. Samples from cantaloupe farms consisted of cantaloupe rinses, irrigation water, water from furrows in the field, and workers' hands. Samples from the chile pepper farm consisted of rinses of chile peppers obtained at the field, pepper rinses obtained at the packing house, and irrigation water from the field. A total of 55 samples were obtained from both production systems. Twelve and 10 samples from the cantaloupe and chile pepper production systems, respectively, tested positive for Salmonella according to a traditional culture method. The difference between the proportion of Salmonella-positive samples from the cantaloupe production system (12 of 28 = 0.43) and the chile pepper production system (10 of 27 = 0.37) was not statistically significant (P > 0.05). A PCR-restriction fragment length polymorphism (RFLP) method based on the fliC gene was used to determine the serotype of the isolates. Salmonella Typhimurium was the only serotype found associated with the cantaloupe production system, whereas both Salmonella Typhimurium and Enteritidis serotypes were found associated with the chile pepper production system. Results showed that 91% (20 of 22) and 9% (2 of 22) of the isolates from both agricultural systems matched with the Salmonella Typhimurium and Salmonella Enteritidis reference strain restriction profiles, respectively. This study demonstrates the utility of the PCR-RFLP technique for determining the serotypes of Salmonella isolates obtained from cantaloupe and chile pepper production systems.

    The electricity generation from renewable resources has acquired a leading role. Mexico particularrly it has great interest in renewable natural resources for power generation, especially wind energy. Therefore, the country is rapidly entering in the development of wind power generators sites. The development of a wind places as an energy project, does not have a standardized methodology. Techniques vary according to the developer to select the best place to install a wind turbine system. Generally to install the system the developers consider three key factors: 1) the characteristics of the wind, 2) the potential distribution of electricity and 3) transport access to the site. This paper presents a study with a different methodology which is carried out in two stages: the first at regional scale uses "space" and "natural" criteria in order to select a region based on its cartographic features such as politics and physiographic division, location of conservation natural areas, water bodies, urban criteria; and natural criteria such as the amount and direction of the wind, the type and land use, vegetation, topography and biodiversity of the site. The result of the application of these criteria, gives a first optimal selection area. The second part of the methodology includes criteria and variables on detail scale. The analysis of all data information collected will provide new parameters (decision variables) for the site. The overall analysis of the information, based in these criteria, indicates that the best location that the best location of the field would be the southern Coahuila and the central part of Nuevo Leon. The wind power site will contribute to the economy grow of important cities including Monterrey. Finally, computational model of genetic algorithm will be used as a tool to determine the best site selection depending on the parameters considered.

    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.

Dario Martinez is one such settlement, a colonia populare, to the city's south-east, just inside the federal district state of Mexico. Smoke pollution, garbage, open sewers, and industrial encroachment are typical for squatter settlements on the periphery. Even so, and despite the comparative lack of economic opportunity forcing people to commute to the city center for employment, the physical quality of life is better that what poor families can find further into the city. Residents in Mexico City are often told not to breathe when they go outside. The most common cause of urban flight in Mexico is therefore to escape the unhealthy environment. There are few urban services in the periphery such as electricity and piped water, but people do not suffer the problems of overcrowding, air pollution, chronic water shortages, and earthquake dangers.

  12. Integrated geographic information systems (IGIS) analysis and definition of the tectonic framework of northern Mexico

    NASA Astrophysics Data System (ADS)

    Martinez Pina, Carlos Manuel

    Crustal rupture structures reactivated in the course of the tectonic history of northern Mexico are the surface expressions of planes of weakness, in the form of simple or composite rectilinear features or slightly curved, defined as lineaments. Unless otherwise defined as strike-slip faults, lineaments are part of parallel and sub-parallel oblique convergent or oblique divergent tectonic zones cross cutting the Sierra Madre Occidental and northern Mexico, in a NW trend. These shear zones are the response to the oblique subduction of the Farallon plate beneath North America. Kinematic analysis of five selected sites in northern Mexico, three basins and two compressional shear zones, proved possible a combination of shear mechanism diagram and models from analogue materials, with satellite imagery and geographic information systems, as an aid to define strike-slip fault motion. This was done using a reverse engineering process by comparing geometries. One of the sites assessed, involving the Parras Basin, Coahuila Block (CB), San Marcos fault, a postulated PBF-1 fault, allowed for palinpastic reconstruction of the CB that corroborated the results of the vector motion defined, in addition to an extension of ˜25% in a northwest southeast direction. A GIS-based compilation and georeferenced regional structural studies by several researchers were used as ground control areas (GCA); their interpolation and interpretation, resulted in a tectonic framework map of northern Mexico. In addition, shaded relief models overlaid by the lineaments / fault layer allowed structural analyses of basins related to these major structures. Two important results were obtained from this study: the Tepehuanes-San Luis-fault (TSL) and the Guadalupe fault, named herein, displaces the Villa de Reyes graben, and the Aguascalientes graben, respectively, to the SE, confirming their left lateral vector motion; afterwards TSL was displaced south by the right lateral strike slip Taxco-San Miguel de

    1995-03-01

    Even though the ALARA philosophy was formally implemented in the early 1980`s, to some extent, ALARA considerations already had been incorporated into the design of most commercial equipment and facilities based on experience and engineering development. In Mexico, the design of medical and industrial facilities were based on international recommendations containing those considerations. With the construction of Laguna Verde Nuclear Power Station, formal ALARA groups were created to review some parts of its design, and to prepare the ALARA Program and related procedures necessary for its commercial operation. This paper begins with a brief historical description of ALARA development in Mexico, and then goes on to discuss our regulatory frame in Radiation Protection, some aspects of the ALARA Program, efforts in controlling and reducing of sources of radiation, and finally, future perspectives in the ALARA field.

    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.

    This invited paper explores the diverse pathways that have led to the development of neuropsychology in Mexico. The authors conducted a review of the literature and their own experiences to describe the seminal events and people relevant to the development of this area of research and practice. The master's degree is the usual level of educational attainment for those who wish to practice clinical neuropsychology. As of now, there is not a board certification process in neuropsychology, although there is one in clinical psychology. Neuropsychology and other mental health disciplines in Mexico and Latin America have historically been poorly funded, and have lacked optimal means of communication as to research findings and clinical initiatives and standards. However, there is reason to think that this will be improved upon in coming years.

    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.

  7. Environmental lead in Mexico.

    PubMed

    Albert, L A; Badillo, F

    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

    1998-01-01

    One hundred and eighty two individual detrital zircon grains from Cambrian through Permian miogeoclinal strata, Ordovician eugeoclinal rocks, and Triassic post-orogenic sediments in northwestern Sonora have been analyzed. During Cambrian, Devonian, Permian, and Triassic time, most zircons accumulating along this part of the Cordilleran margin were shed from 1.40-1.45 and 1.62-1.78 Ga igneous rocks that are widespread in the southwestern United States and northwestern Mexico. Zircons with ages of approximately 1.11 Ga are common in Cambrian strata and were apparently shed from granite bodies near the sample site. The sources of 225-280 Ma zircons in our Triassic sample are more problematic, as few igneous rocks of these ages are recognized in northwestern Mexico. Such sources may be present but unrecognized, or the grains could have been derived from igneous rocks of the appropriate ages to the northwest in the Mojave Desert region, to the east in Chihuahua and Coahuila, or to the south in accreted(?) arc-type terranes. Because the zircon grains in our Cambrian and Devonian to Triassic samples could have accumulated in proximity to basement rocks near their present position or in the Death Valley region of southern California, our data do not support or refute the existence of the Mojave-Sonora megashear. Ordovician strata of both miogeoclinal and eugeoclinal affinity are dominated by >1.77 Ga detrital zircons, which are considerably older than most basement rocks in the region. Zircon grains in the miogeoclinal sample were apparently derived from the Peace River arch area of northwestern Canada and transported southward by longshore currents. The eugeoclinal grains may also have come from the Peace River arch region, with southward transport by either sedimentary or tectonic processes, or they may have been shed from off-shelf slivers of continents (perhaps Antarctica?) removed from the Cordilleran margin during Neoproterozoic rifting. It is also possible that the

    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.

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.

  10. Terrorism in Mexico.

    PubMed

    Nordin, Yannick; Cruz-Vega, Felipe; Roman, Fernando

    2003-01-01

    Even though Mexico is considered internationally as a pacifist country, its economic, social, and geopolitical characteristics during the last half of the 20th century have resulted in internal events that can be considered acts of terrorism. Most of the acts of terrorism during the last 15 years have had to do either with political movements or drug-dealing actions. After the 11 September 2001 attacks in the United States, Mexican Health Authorities have strengthened the epidemiological surveillance system. More than 1,372 calls asking for information or reporting suspicious envelopes were received between 16 October and 21 October 2001. Following the earthquake in 1985 that caused great damage and many deaths in Mexico, the National Civil Protection System was created in 1986. This protection system is led by the President and the Secretary of Government. It was developed to improve preparedness for disaster coordination more than for terrorism responses. In addition, the emergency medical systems continue to lack organization, even though some states have shown significant progress in their emergency medical system.

  11. Mexico City Subsidence

    NASA Astrophysics Data System (ADS)

    Osmanoglu, B.; Dixon, T. H.; Cabral-Cano, E.; Wdowinski, S.

    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.

    Schwartz, M.N.; Elliott, D.L.

    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.

    For the past week, the Borrego Fire in northern New Mexico has consumed over 12,000 acres of land in and around the Sante Fe National Forest. This true-color image of the fire was acquired on May 24, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra satellite. The fire, which has been fueled by unseasonably dry mixed conifer and aspen forests, is reported to have spread very little in the past twenty-four hours. Eight hundred firefighters, four air tankers, and 12 helicopters have been employed to control the blaze. As of now, the cause of the fire is still under investigation, and no one has been seriously injured or killed. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC

    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.

  18. Mexico's population policy turnaround.

    PubMed

    Nagel, J S

    1978-12-01

    Until 1972 Mexico's officials seemed to believe that the annual population growth rate of 3.5% was not really a problem as long as the economic development rate could be kept ahead of the population growth rate. The General Law of Population of 1947 was actually promoting population growth. It was only during the 1960s that elite opinion shifted, and privately funded family planning programs became increasingly active. By 1972 the population had reached 54 million, from 20 million in 1940. President Echevarria, till then a traditional pronatalist, announced in 1972 the creation of a national family planning program, and, in 1974, the creation of a national population council. Since then the Mexican government has embarked on ambitious programs of mass communication and sex education to make the population receptive to its new attitudes. The plans have worked: by mid-1979 estimates put the population growth rate at 2.9%, within sight of the 2.5% target set for 1982 by new president Lopez Portillo. According to a survey conducted by the National Fertility Survey, by late 1976 41.50% of Mexican women of childbearing age were practicing contraception. Within the 41.50% of active contraceptors, 14.9% use the pill, and 7.8% the IUD. New channels of information and of contraceptive delivery are being explored to reach Mexico's widely scattered rural population, and to bring the average family size down to 2 children from the average of 6.5 children per woman for 1973-1975. The government goal is of a 1% population increase by the year 2000.

    2007-05-01

    The Mexicali Valley, which is part of the Salton Trough, is located within an active tectonic region, in the boundary between the Pacific and North American plates; a region featuring a wide zone of transform faults associated with San Andreas fault system, and a zone of distributed deformation in the pull-apart center of Cerro Prieto. Since 1996, geotechnical instruments have operated in the Valley, for continuous recording of deformation phenomena. To date, the network includes three crackmeters, eight tiltmeters, and seven piezometers installed in the shallow aquifer; all instruments have sampling intervals in the 1 to 20 minutes range. The mainly vertical displacement at Saltillo fault (known before as southernmost part of Imperial fault) has been measured on a continuous basis since February 1996 by a crackmeter installed in Ejido Saltillo (Glowacka 1996; Nava and Glowacka, 1999). In 1998 a tiltmeter was installed on the fault and a second crackmeter , in a horizontal direction, about 60° from the fault strike, was installed about 1 km south of ES. Another crackmeter in the vertical plane crossing Morelia fault and a 3D Witness on the Cerro Prieto fault were installed in 2004. In 2003 seven digital water level meters were installed at depths up to 500 meters in the local piezometric wells, with the purpose of recording aquifer level changes. The observed deformation rates measured on the Saltillo fault are 6 cm/yr and 2 cm/yr for the vertical and horizontal components, respectively and occurs in steps (creep events), separated by months of quiescence, and large events account for 70 percent of the vertical displacement. Aseismic creep events have amplitudes of 1-3 cm and durations of 1-3 days. Much less precise measurements from the Cerro Prieto fault show vertical deformation on the fault with velocity around 3.1 cm/yr , and the rate does not depend on the local seismicity. Horizontal rates change slightly with the presence of seismicity when very small

    The Naica mine in Chihuahua, Mexico, with its enormous gypsum crystals, may well be called the "Queen of the Giant Crystals localities." Though the Naica mine is no show mine, but still a working lead-zinc mine hosted in layered limestones, the first of several crystal caves was discovered in 1910. This "Cave of the Swords" contained extraordinary large sword-like selenite (gypsum) crystals up to 2 m long. In 2000 another crystal cave system was discovered at 300 m depth, even more spectacular than the original cave. Inside were free growing gypsum crystals up to 12 m long and 2 m in diameter. The ASTER image uses SWIR bands 4, 6, and 8 in RGB. Limestone is displayed in yellow-green colors, vegetation is red. The image was acquired February 16, 2004, covers an area of 26 x 23.5 km, and is located near 27.8 degrees north latitude, 105.5 degrees west longitude.

    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.

    1986-01-01

    Population increase, rural-to-urban migration, excessive population concentration side by side with scattered rural populations, and the economic crisis provide the primary framework for this analysis of health manpower in Mexico. The secondary frame of reference is the primary causes of mortality (in 1981): the leading cause, accidents and violence; the second, heart disease; the third, influenza and pneumonia; and the fourth, enteric diseases and diarrheas. Data are supplied on the number of new physicians graduating (this number rose from 2,493 in 1976 to 14,099 in 1983), and on the number of nurses (about 98,000, of which 40% are professionals). The growth pattern of the contingent of dentists is the same as that of physicians, namely, disproportionate and inefficient. The Federal Government is now trying to set up a National Health System that will fulfill the constitutional right of all Mexican citizens to health protection. On the basis of the disequilibrium apparent in every part of the health sector, the author recommends that educational and health institutions plan and coordinate the training of physicians so that the number of graduates may meet the country's needs, and the quality of their education may be improved.

    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.

    The history of health technology assessment (HTA) in Mexico is examined, starting with the efforts to incorporate this topic into the policy agenda and culminating with the recent creation of a specialized public agency. Information was gathered through a bibliographic search and interviews with actors involved in HTA in Mexico. HTA efforts were developed in Mexico since the mid-1980s with the participation both of academics and of policy makers, a relationship that eventually led to the creation of the Center for Technological Excellence within the Ministry of Health. Institutionalization of HTA in resource-constrained settings requires the development of a critical mass of researchers involved in this field, the implementation of information efforts, and the establishment of strong relationships between HTA experts and policy makers.

    Fierro, J.

    2006-08-01

    Mexico has added five more years of compulsory education to its national education system. In the past it only included six year of elementary (grammar) school. Now three years of pre school (kinder garden) and three years of middle school are being implemented. At present an optional course on astronomy if offered in high school (pre college). During my presentation I shall discuss problems concerning education in Mexico; mainly the lack of continuity in different levels of education, the lack of teacher training in science in general and the few topics of astronomy that are addressed. I shall mention for teacher training and public education, which includes books, lectures and videos.

    New Mexico was inhabited thousands of years ago. Each group of settlers saw the land in distinct ways. For some, its beauty consisted of its quality, the abundance of water, and the hope of a good harvest. For others, its beautiful sites were of more importance. Thus, each group established its own manner of living on the land and of using it.…

  11. Opportunity for America: Mexico`s coal future

    SciTech Connect

    Loose, V.W.

    1993-09-01

    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.

  18. Risk to Drought in Mexico

    NASA Astrophysics Data System (ADS)

    Magana, V.

    2016-12-01

    Drought is one of the major meteorological hazards in Mexico given the semiarid and arid conditions in most of its territory. The recent drought event between 2011 and 2013 led to one of the major socioeconomic and environmental crisis in recent years in relation to water deficit mainly in northern Mexico. But the impacts of meteorological droughts are not only related to precipitation deficit, but to the water crisis context in which the climatic anomaly occurs. In other words, the drought hazard occurs in a vulnerability context that results in risks at levels that translate into hydrological, agricultural and socioeconomic droughts. The dynamics of prolonged droughts in Mexico has been studied in relation to low frequency oscillations in the Pacific and Atlantic oceans (Méndez and Magaña 2010). On the other hand, the vulnerability to drought has been characterized by means of socioeconomic and physical indicators that reflect the dynamical and multifactorial characteristics of this element (Neri and Magaña 2016). The combination of hazard and vulnerability led to an estimate of risk to drought that explains the drought impacts in recent years. The Mexican government has developed a national strategy to prevent or at least ameliorate the impacts of droughts by establishing the National Program against Drought (PRONACOSE) for each one of the thirteen hydrologic administrative regions that compose the Mexican territory. The main idea behind PRONACOSE is to respond to drought as it reaches a higher level of intensity. Some of the protocols in PRONACOSE are based on a risk analysis and proposals by water stakeholders. It is found that PRONACOSE could better work if a risk management preventive scheme is implemented making use of the knowledge on the predictability of drought in Mexico on various time scales. The examples of potential risk to drought management schemes in Mexico for some of the hydrologic administrative regions are presented.

  4. 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

  8. 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

    2001-01-23

    ISS01-E-5316 (23 January 2001) -- Popocatépetl, or Popo, the active volcano located about 70 kilometers southeast of Mexico City, sends a plume south on January 23, 2001. The Expedition One crew onboard the International Space Station (ISS) observed and recorded this image with a digital still camera as it orbited to the northeast of the volcano. Popo has been frequently active for six years. On this day, the eruption plume reportedly rose to more than 9 kilometers above sea level (for reference, Popo's summit elevation is 5426 meters). Note the smaller ash plume below the main plume. The perspective from the ISS allowed the crew members this unique three dimensional view. Popo is situated between two large population centers: Mexico City (more than 18 million people, and just out of this image at right) and Puebla (about 1.2 million people), partially visible at lower left.

  12. History of nonnative Monk Parakeets in Mexico.

    PubMed

    Hobson, Elizabeth A; Smith-Vidaurre, Grace; Salinas-Melgoza, Alejandro

    2017-01-01

    Nonnative Monk Parakeets have been reported in increasing numbers across many cities in Mexico, and were formally classified as an invasive species in Mexico in late 2016. However, there has not been a large-scale attempt to determine how international pet trade and national and international governmental regulations have played a part in colonization, and when the species appeared in different areas. We describe the changes in regulations that led the international pet trade market to shift to Mexico, then used international trade data to determine how many parakeets were commercially imported each year and where those individuals originated. We also quantified the recent increases in Monk Parakeet (Myiopsitta monachus) sightings in Mexico in both the scientific literature and in citizen science reports. We describe the timeline of increased reports to understand the history of nonnative Monk Parakeets in Mexico. As in other areas where the species has colonized, the main mode of transport is through the international pet trade. Over half a million Monk Parakeets were commercially imported to Mexico during 2000-2015, with the majority of importation (90%) occurring in 2008-2014, and almost all (98%) were imported from Uruguay. The earliest record of a free-flying Monk Parakeet was observed during 1994-1995 in Mexico City, but sightings of the parakeets did not become geographically widespread in either the scientific literature or citizen science databases until 2012-2015. By 2015, parakeets had been reported in 97 cities in Mexico. Mexico City has consistently seen steep increases in reporting since this species was first reported in Mexico. Here we find that both national and international legal regulations and health concerns drove a rise and fall in Monk Parakeet pet trade importations, shortly followed by widespread sightings of feral parakeets across Mexico. Further monitoring of introduced Monk Parakeet populations in Mexico is needed to understand the

  13. Perspectives of hadron therapy in Mexico

    The need for a hadron therapy center in Mexico is presented. The question if such a facility is affordable in Mexico is discussed, addressing the economical factor as well as the expertise and know how available in both the private and the public sector. To conclude, a possible path, and the first steps on it, to move forward towards a medical facility in Mexico devoted to proton therapy are sketched.

  15. History of nonnative Monk Parakeets in Mexico

    Smith-Vidaurre, Grace; Salinas-Melgoza, Alejandro

    2017-01-01

    Nonnative Monk Parakeets have been reported in increasing numbers across many cities in Mexico, and were formally classified as an invasive species in Mexico in late 2016. However, there has not been a large-scale attempt to determine how international pet trade and national and international governmental regulations have played a part in colonization, and when the species appeared in different areas. We describe the changes in regulations that led the international pet trade market to shift to Mexico, then used international trade data to determine how many parakeets were commercially imported each year and where those individuals originated. We also quantified the recent increases in Monk Parakeet (Myiopsitta monachus) sightings in Mexico in both the scientific literature and in citizen science reports. We describe the timeline of increased reports to understand the history of nonnative Monk Parakeets in Mexico. As in other areas where the species has colonized, the main mode of transport is through the international pet trade. Over half a million Monk Parakeets were commercially imported to Mexico during 2000–2015, with the majority of importation (90%) occurring in 2008–2014, and almost all (98%) were imported from Uruguay. The earliest record of a free-flying Monk Parakeet was observed during 1994–1995 in Mexico City, but sightings of the parakeets did not become geographically widespread in either the scientific literature or citizen science databases until 2012–2015. By 2015, parakeets had been reported in 97 cities in Mexico. Mexico City has consistently seen steep increases in reporting since this species was first reported in Mexico. Here we find that both national and international legal regulations and health concerns drove a rise and fall in Monk Parakeet pet trade importations, shortly followed by widespread sightings of feral parakeets across Mexico. Further monitoring of introduced Monk Parakeet populations in Mexico is needed to understand

    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.

    Diabetes has demonstrated an epidemic behavior in Mexico, which is among the top countries with the highest number of patients with diabetes. The objective of this study was to estimate the prevalence of type 2 diabetes in Mexico City and its relation with some cardiovascular risk factors. A cross-sectional study was conducted. A total of 1,772 adults of both genders, aged 25 to 64 years, were randomly selected. Type 2 diabetes and impaired fasting glucose prevalence were estimated as well as its relation with some cardiovascular risk factors such as hypertension, dyslipidemia, obesity, abdominal obesity and the common carotid artery intima-media thickness. The prevalence of type 2 diabetes was 9.7% in women and 8.0% in men. An age effect was evident. The proportion of patients who were unaware of having diabetes was 26%. The main risk factors related to diabetes were age, abdominal obesity, hypertension, low high-density cholesterol lipoproteins (HDL-c) and hypertriglyceridemia. Metabolic control was low. Prevalence of type 2 diabetes in Mexico is high and is a major health problem. Its close relation with cardiovascular risk factors demand health policies aimed to diminish risk factors related to its occurrence.

  7. Environmental radon studies in Mexico.

    PubMed

    Segovia, N; Gaso, M I; Armienta, M A

    2007-04-01

    Radon has been determined in soil, groundwater, and air in Mexico, both indoors and outdoors, as part of geophysical studies and to estimate effective doses as a result of radon exposure. Detection of radon has mainly been performed with solid-state nuclear track detectors (SSNTD) and, occasionally, with active detection devices based on silicon detectors or ionization chambers. The liquid scintillation technique, also, has been used for determination of radon in groundwater. The adjusted geometric mean indoor radon concentration (74 Bq m-3) in urban developments, for example Mexico City, is higher than the worldwide median concentration of radon in dwellings. In some regions, particularly hilly regions of Mexico where air pollution is high, radon concentrations are higher than action levels and the effective dose for the general population has increased. Higher soil radon levels have been found in the uranium mining areas in the northern part of the country. Groundwater radon levels are, in general, low. Soil-air radon contributing to indoor atmospheres and air pollution is the main source of increased exposure of the population.

  8. Rural health care in Mexico?

    PubMed

    Cañedo, L

    1974-09-27

    A very large percentage of Mexico's population living in rural areas lacks resources for health care. Any new effort to provide such care must emphasize the health of the infant population because of the high percentage of infants in the country. Plans made at the national level have not been correlated with the conditions that exist in rural areas. For example, the majority of university programs are oriented toward urban medical practice, and the construction of more schools of medicine to solve the problem of doctors in rural areas is based on a mistaken premise. This problem has not been solved even in developed countries such as the United States where, as in Mexico, graduates in medicine migrate to the cities where optimal conditions are met for practicing the type of medicine for which they have been trained. Furthermore, it is both expensive and illogical to maintain urban doctors in rural areas where they cannot practice their profession for lack of resources; to do so is to deny the purpose of their education (27). Conventional schools of medicine, for reasons of investment and of structure, should teach only very selected groups of students who, on finishing their training, are fully capacitated to practice specialized medicine. A different system is required if we are to provide adequate health care in the rural communities. A system such as that described herein, adapted to the real need of rural communities, would avoid the necessity to create dysfunctional bureaucracies and would not destroy those institutions which have proved useful in the past. This study should be considered as one of the many pilot programs that should be initiated in order to determine the type of program that would best solve the problem of health care in rural Mexico. Other programs already being considered at the National Autonomous University of Mexico include the A36 plan of the Faculty of Medicine, now in operation; the work of C. Biro carried out in Netzahualcoyotl City

  20. Petrographic Evidence of Microbial Mats in the Upper Cretaceous Fish-Bearing, Organic-Rich Limestone, Agua Nueva Formation, Central Mexico

    We document petrographic evidence of microbial mats in the Upper Cretaceous Agua Nueva Formation in the area of Xilitla (San Luis Potosí, Central Mexico), located in the southern part of the Tampico-Misantla basin. The sequence consists predominantly of alternating decimeter-thick beds of fossiliferous dark laminated limestone (C-org > 1.0wt%), and light gray, bioturbated limestone (C-org < 1.0wt%), with occasional brown shale and green bentonite layers. Well-preserved fossil-fish assemblages occur in the laminated dark limestone beds, which include shark teeth (cf. Ptychodus), scales of teleosteans (Ichthyodectiformes), as well as skeletal remains of holosteans (Nursallia. sp), and teleosteans (cf. Rhynchodercetis, Tselfatia, and unidentified Enchodontids). Thin section and SEM analyses of the laminated, dark limestones, reveal a micritic matrix consisting of dark and light sub-parallel wavy laminae, continuous and discontinuous folded laminae with shreds of organic matter, filaments, oncoids, and interlocking structures. The structures are identical to those previously described for the Cenomanian-Turonian Indidura Fm at Parras de la Fuente (Coahuila state) demonstrated to be of microbial origin (Duque-Botero and Maurrasse, 2005; 2008). These structures are also analogous to microbial mats in present environments, and Devonian deposits (Kremer, 2006). In addition, the laminae at Xilitla include filamentous bacterial structures, as thin and segmented red elements. In some thin sections, filaments appear to be embedded within the crinkly laminae and shreds showing the same pattern of folding, suggestive of biomorphic elements that represent the main producers of the organic matter associated with the laminae. Thus, exceptional bacterial activity characterizes sedimentation during the accumulation of the Agua Nueva Formation. Oxygen-deficient conditions related to the microbial mats were an important element in the mass mortality and preservation of the fish

  1. 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.

  2. New horizons for Mexico's women.

    PubMed

    Pando De Cosio, R

    1993-11-01

    In Mexico, a rural woman's sole worth lies in her ability to have children. Her husband's status in the community also rests on this ability. Family planning and enjoyment of sex by a woman are taboo. Physical abuse of women by men is accepted and common. Education of young girls and women, which leads to increase self-esteem and trust in outsiders, is necessary to begin the process that will allow rural women to take control of their lives and their relationships with men. This process is the adoption of family planning practices.

    1984-01-01

    On the basis of a mineral survey the White Mountain Wilderness, which constitutes much of the western and northern White Mountains, New Mexico, is appraised to have six areas of probable mineral potential for base and precious metals. If mineral deposits exist in the wilderness, the potential is for small deposits of base and precious metals in veins and breccia pipes or, more significanlty, the possibility for large low-grade disseminated porphyry-type molybdenum deposits. There is little promise for the occurrence of geothermal energy resources in the area.

    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.

    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.

    An outbreak of myxomatosis occurred between September and October 1993 on a rabbit farm in Punta Colnett (Ensenada, Baja California in northwestern Mexico, Transpeninsular Highway, km 128) and was confirmed by the Mexico-USA Commission for Prevention of Foreign Diseases of Animals (CPA). This represents the first officially confirmed case of the disease in Mexico. Like the cases in California (USA), the brush rabbit (Sylvilagus bachmani) seems to be the carrier of the virus, since serum samples from wild rabbits from different areas of the peninsula of Baja California were found to contain antibodies against the myxoma virus.

    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.

    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.

    López-Arellano, O; Blanco-Gil, J

    2001-01-01

    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.

    2001-10-01

    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

  10. Mexico: a model for success.

    PubMed

    Potter, J E

    1986-03-01

    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.

  11. Southern Mexico Miocene Magmatic Activity

    NASA Astrophysics Data System (ADS)

    Layer, P.

    2006-12-01

    Magmatic activity in southern Mexico have been occurred in three important volcanic regions: Los Tuxtlas Volcanic Field (TVF), Chiapanecan Volcanic Arc (CVA), and Tacaná Volcanic Complex (TVC). This activity produce alkaline and calc-alkaline products. The TVF has been active since 7 Ma ago producing Na-alkaline basanite, trachybasalt, and trachyandesite (41 63 wt% SiO2), and calc-alkaline basalts, basaltic-andesites, and andesites (45 63 wt% SiO2). The CVA including El Chichon Volcano produced calc-alkaline magmas varying from andesites to dacites (57 65 wt% SiO2) emitted between 2100 ka ago (Tzontehuitz) to 225 ka and K-alkaline magmas emitted from 1.1 Ma ago (trachybasalt, 46 51 wt% SiO2) to the Recent (trachyandesite, 57 63 wt% SiO2). The TVC emitted calc-alkaline products varying from basaltic-andesite (52 57 wt% SiO2) as mafic enclaves, andesites (57 63 wt% SiO2), and dacites (63 68 wt% SiO2). El Chichón and TVF present slight enrichments in K2O, Na2O, Rb, Sr, Th, U, Cs, and LREE respect to TVC, these are signatures related to subduction environment. The presence of alkaline magmas at El Chichón and TVF correspond to mantle low degree melts that reach the surface along with calc-alkaline lavas due to a tensional stress field that allows their pass to the surface. In the generation of the magmas of southern Mexico three components are involved: mantle partial melting fluids, fluid from subducted lithosphere, and continental crust, likely interacting in different ratios through time and in different proportions from SW to NE.

    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.

    The main etiology of liver disease in Mexico is alcohol and viral hepatitis. The aim of the present study was to analyze the current epidemiology of viral hepatitis in Mexico. From 2000 to 2007 the Ministry of Health reported 192 588 cases of hepatitis, 79% HAV, 3.3% HBV, 6% HCV, and 12% without a specific etiologic factor. Due to high endemic areas for HBV infection in native Mexican population, limitations in the diagnostic sensitivity and specificity of the serological immunoassays used to date and presence of occult hepatitis B in the country, the real prevalence of HBV infection could be even higher than HCV in Mexico. Hepatitis E virus in cirrhotic patients and in porcine farms could at least partially explain the cases of hepatitis that are diagnosed without a specific etiologic agent. Specific strategies to establish control regulations against viral hepatitis infections in Mexico are proposed.

    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.

    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

    At the 1984 United Nations International Conference on Population held in August, delegates from 149 countries affirmed that population dynamics are an intrinsic part of development and that all people, including adolescents, have a right to family planning information and services. Despite concern for continued US support for population activities, the US delegation in Mexico City clearly emphasized its government's commitment to increased funding. The conference also accepted by acclamation the Mexico City Declaration on Population and Development drafted by 29 countries which stresses the importance of increased funding for population policy, the urgent need to improve women's status and the concern for the effects of the deepening economic crisis, Legal abortion and voluntary sterilization as fertility determinants were ignored. The meeting put to rest any notion that population and development activities are competing spheres of action. In contrast to its 1974 position, the US emphasized entrepreneurial initiative within a free-market system as a stimulus to economic development. The status of women was a major issue brought up by the delegations of Zimbabwe and Australia. The crucial but uncertain issue of funding was addressed by most country represehntatives and most developed countries pledged at least continued if not increased funding for development programs. Most discussion on the abortion issue was almost universally based on repudiation of the procedure as a family planning method. The role of the US in the abortion issue is discussed. The US criticized 2 international agencies that provide most of family planning services to which the US provides funding but which are promoting abortion through affiliates. The US affirmed it would not participate in or assist abortion promotion as a birth control method. The nature and scope of the current economic world crisis caused profound differences between the US and most developing countries' delegations

    Solar power towers, based on molten salt technology, have been the subject of extensive research and development since the late 1970s. In the mid 1980s, small experimental plants were successfully fielded in the USA and France that demonstrated the feasibility of the concept at a 1 to 2 MW{sub e} scale. Systems analyses indicate this technology will be cost competitive with coal-fired power plants after scaling-up plant size to the 100 to 200 MW{sub e} range. To help bridge the scale-up gap, a 10 MW{sub e} demonstration project known as Solar Two, was successfully operated in California, USA from 1996 to 1999. The next logical step could be to scale-up further and develop a 30 MW{sub e} project within the country of Mexico. The plant could be built by an IPP industrial consortium consisting of USA's Boeing and Bechtel Corporations, combined with Mexican industrial and financial partners. Plausible technical and financial characteristics of such a ``Solar-Two-type'' Mexican project are discussed in this paper.

    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.

    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.

    This is the second part of a research report on the evolution and magnitude of poverty in Mexico. Application of the Integrated Poverty Measurement Method, explained in the first part of this report, shows a poverty headcount ratio (H) of 70.6% and an extreme poverty H of 44.7%. H turns out higher by the UBN (Unsatisfied Basic Needs) method than by the PLT (Poverty Line plus working time) approach. The poverty gap or poverty intensity (I), is for all poor 0.44 but reaches 0.58 for the extremely poor. Both H and I are substantially higher in the rural than in the urban areas. UBN poverty gap is bigger than the PLT gap. When UBN is disaggregated into its components, deprivation turns out the highest in health care and social security. Degree of poverty calculations (HI), the product of H and I, which constitute a good basis for anti-poverty expenditures allocation, show that despite the fact that a larger number of poor persons live in the urban areas, the number of equivalent poor people is higher in the rural areas.

    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.

    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

    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 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.

    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.

  10. Growth through conservation: DSM in Mexico

    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.

    Stemming from the 2010 cholera outbreak in Haiti, cholera transmission in Hispaniola continues with over 40,000 cases in 2013. The presence of an ongoing cholera outbreak in the region poses substantial risks to countries throughout the Americas, particularly in areas with poor infrastructure. Since September 9, 2013 nearly 200 cholera cases have been reported in Mexico, as a result of introductions from Hispaniola or Cuba. There appear to have been multiple introductions into Mexico resulting in outbreaks of 2 to over 150 people. Using publicly available data, we attempt to estimate the reproductive number (R) of cholera in Mexico, and thereby assess the potential of continued introductions to establish a sustained epidemic. We estimate R for cholera in Mexico to be between 0.8 to 1.1, depending on the number of introductions, with the confidence intervals for the most plausible estimates crossing 1. These results suggest that the efficiency of cholera transmission in some regions of Mexico is near that necessary for a large epidemic. Intensive surveillance, evaluation of water and sanitation infrastructure, and planning for rapid response are warranted steps to avoid potential large epidemics in the region.

    of +5.5‰ - +6.7‰ (± <1‰). These data are best explained by MASH processes where mantle-derived magmas introduced to the base of accreted (e.g., Guerrero terrane) and hybridized (Jurassic - Eocene arc magmatism) continental lithosphere caused melting and assimilation in the lower and middle crust. Melting of shallow crust is unlikely because of the absence of negative δ18O values. Three samples erupted in the extreme northeast of the region proximal to outcrops of Grenville-age basement (Coahuila block) have ɛHf values of -3 - -4 suggesting assimilation of cratonic lithosphere and addition of lesser volumes of juvenile, mantle-derived material. Combined, these data indicate prolonged and relatively steady-state MASH processes operated during migration of the magmatic arc SW across N. Mexico over 20 Myrs.

  15. Cyanobacteria/Foraminifera Association from Anoxic/Dysoxic Beds of the Agua Nueva Formation (Upper Cretaceous - Cenomanian/Turonian) at Xilitla, San Luis Potosi, Central Mexico

    The Agua Nueva Formation in the vicinity of Xilitla, State of San Luis Potosí, Central Mexico, consists of interbedded brown shale (Grayish orange 10YR 7/4 to Moderate yellowish brown 10YR 5/4) and dark-gray fossiliferous limestone (Bluish gray 5B 6/1 to Dark bluish gray 5B 4/1), varying between 10 and 20 cm in thickness. The sequence also includes 2 to 4 cm- thick intermittent bentonite layers (Moderate greenish yellow 10Y 7/4, to dark greenish yellow 10Y 6/6 and Light olive 10Y 5/4). At the field scale, shaly intervals show no apparent internal structures, whereas most limestone beds show primary lamination at the millimeter scale (1-2 mm), and intermittent layers of black chert of about 5 cm thick. Pyrite is present as disseminated crystals and as 2 cm-thick layers. Bioturbation or macrobenthic organisms other than inoceramids do not occur in the Agua Nueva Formation at Xilitla. Unusual macrofossils are present only in limestone strata, and consist of well- preserved diverse genera of fishes such as sharks, Ptychodus sp. and teleosteans, Rhynchodercetis sp., Tselfatia sp., Goulmimichthys sp., and scales of Ichtyodectiformes, as well as ammonites and inoceramids (Blanco et al., 2006). The presence of Inoceramus (Mytyloides) labiatus (Maldonado-Koederll, 1956) indicates an Early Turonian age for the sequence. Total carbonate content (CaCO3 = TIC) varies between 62 and 94% in the Limestone beds, which yield Total Organic Carbon (TOC) from 0.4% to 2.5%; the shale intervals contain TIC values consistently lower than 33% and TOC lower than 0.8% Microscopically the limestone beds vary from mudstone to packstone composed essentially of coccoid cyanobacteria similar to coeval deposits in northeastern Mexico, Coahuila State, at Parras de La Fuente (Duque- Botero 2006). Similarly, the microspheroids are spherical to sub-spherical, and occur as isolated elements or aggregates forming series of chains of parallel-packed light lamina 1-2 mm thick.

    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.

    Luna-Zaragoza, D; Reyes-Frías, M L

    2001-01-01

    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.

  15. Renewable energy for productive uses in Mexico

    SciTech Connect

    Hanley, C.

    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.

    2016-07-12

    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.

    Twenty giant oil and gas fields were discovered in Mexico during the period of 1978-1988. The fields, located in adjacent areas, are described in terms of stratigraphy, tectonics, and general characteristics of the reservoirs. Production and reserves figures are also included. The two main oil productive areas in Mexico, Chiapas-Tabasco and offshore Campeche Sound, contribute 92% of Mexico's Mesozoic production. Production comes from Upper Jurassic carbonates; Cretaceous calcareous breccias, limestones, and dolomites; and from lower Paleocene calcareous breccias. The fields represented include 11 from the Chiapas-Tabasco area (Agave, Paredon, Iris, Giraldas, Cardenas, Jujo, Bellota, Tecominoacan, Muspac, Sen, and Luna) and nine from the the Campeche Sound area (Abkatun, Ku, Chuc, Ek, Pol, Malob, Caan, Uech, and Batab).

    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.

This zoonosis remains a great problem to public health in developing countries, although developed countries have successfully controlled it. Mexico still shows a high annual brucellosis incidence in humans; thus, the country is considered around the world as an endemic brucellosis country. To describe the connection/association between this zoonosis and the current epidemiological situation in the Mexican population. Perusal of research reports, epidemiological studies and veterinarian reviews performed in Mexico, using data bases such as PubMed, Thompson Reuters, Mesh research. The risk of infection by Brucella in Mexico is associated with the consumption of unpasteurized dairy products, mainly fresh cheeses.

    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.

    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

    2017-01-20

    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.

  16. On Pemex`s shoulders - update: Mexico`s currency devaluation

    SciTech Connect

    1995-03-30

    The peso has continued to fall versus the dollar despite recent attempts by concerned parties to stop the descent. International elements look towards one of Mexico`s fundamental strengths, oil. The US Congress did not fully support President Clinton`s $40-billion foreign aid package for Mexico. Clinton has since abandoned the package and instead organized a $50-billion package including $20-billion from the US by Presidential order, $17.8-billion from the IMF, $10-billion from the Bank for International Settlements, and $2-billion form Latin American countries. The notable factor in the loan from the US is use of Mexican oil exports revenue as collateral. This is a first for Mexico, a country that constitutionally protects its oil from outside control. The strength of the Mexican economy is closely linked to oil as Pemex comprises roughly 6% of the GDP and is the largest source of exports as well as foreign currency.

  19. 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.

  11. Return Migration to Mexico: Does Health Matter?

    PubMed

    Arenas, Erika; Goldman, Noreen; Pebley, Anne R; Teruel, Graciela

    2015-12-01

    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.
