The Rio Bravo (Rio Grande) adjoins various states in the Mexican region and has a great importance in water distribution in the northeast Tamaulipas (Mexico). In this work 161 strains were isolated, identified and characterized from the water samples taken from the flow of the Rio Bravo and the two inner canals that cover Reynosa city. The strains were identified as V. cholerae (74.5%), Vibrio spp. (1.2%) and V. mimicus (0.6%). Furthermore, the detected virulence genes in the V. cholerae strains, were the hlyA, ompU, tcpA, toxR genes in 78.3%, 62.5%, 15.8% and 90.8%, respectively. Only the ompU and vmh genes were detected in the V. mimicus strain. These results indicate the presence of multi-toxigenic V. cholerae strains in the Rio Bravo/Grande and in the water bodies from Reynosa city, which could represent a risk for the exposed population.

Near-coastal ocean variability off southern Tamaulipas - northern Veracruz, western Gulf of Mexico, during spring-summer 2013

Rivas, David

2016-04-01

Six months of observations from a near-coastal mooring deployed off southern Tamaulipas-northern Veracruz coast (western Gulf of Mexico) during spring-summer 2013 provides velocity, temperature, salinity, sea level, and dissolved oxygen series in a region which ocean dynamics is still poorly understood. As shown in a preceding analysis of this region's winter circulation for winter 2012-2013, coastal trapped motions associated with the regional invasion of synoptic cold fronts modulate the local variability; this pattern remains in the spring 2013, when even more intense events of alongshore flow (>50 cm/s) are observed. This intensified flow is associated with a significant decrease in the dissolved oxygen, most probably related to an influence of hypoxic waters coming from the northern Gulf. In late spring-mid summer, the wind pattern corresponds to persistent southeasterly winds that favor the occurrence of a local upwelling, which maintains a local thermal reduction (>3 degrees Celsius) and is associated with a persistent northward flow (>30 cm/s). The late summer was characterized by a significant tropical-cyclone activity, when a depression, a storm, and a hurricane affected the western Gulf. These tropical systems caused an intense precipitation and hence an important intensification of the local riverine discharge, and the winds enhanced the mixing of such riverine waters, via mostly kinetic stirring and Ekman pumping.

The limiting factors in agricultural production, defined as those properties and characteristics of the geographical environment that influence the development of crops, can be diverse and are grouped with the physical environment of soil. They are the result of soil characteristics and soil degradation processes by anthropogenic influence. Due to the above, the objective of this study was to identify and surveying the limitative factors to agricultural production, as well as to define its ability land use capacity in San Fernando district, Tamaulipas.

Full Text Available This article provides an assessment of a public private partnerships (PPP among the German Technical Cooperation (GTZ, the Municipality of Altamira, Tamaulipas, Mexico and private counterparts BASF Mexicana and Terminal de LNG de Altamira (TLA. The municipality of Altamira, located in the urban-industrial hub of southern Tamaulipas, Mexico, faces important challenges in the field of urban public service delivery, particularly waste management, due to a high demographic growth rate and chronic budgetary constraints. The partnership was formed as a means to develop and implement the Municipal Program for the Prevention and Integrated Management of Solid and Special Wastes. The paper discusses the efficacy of the PPP as a policy instrument for the implementation of integrated solid waste management. As an assessment method, the authors draw on GTZ’s success criteria for the cooperation with the private sector. Criteria include the degree of complementarity, subsidiarity, neutrality and quality of private sector contributions. We argue that this PPP displays a pioneering alliance structure, since the private sector becomes a direct ally in creating strategies for the promotion sustainable development and not simply an exclusive contractor for urban public services delivery or a recipient of incentives from international development cooperation. The PPP provides a means to reach corporate social and environmental responsibility goals while at the same time it promotes development-related policy goals enshrined in the bilateral cooperation agreement between Germany and Mexico. However, the alliance faces important challenges related to different organizational cultures, electoral times and citizen participation.Cet article évalue un partenariat public-privé (PPP entre GTZ (société allemande de coopération technique, la municipalité d’Altamira, dans l’état du Tamaulipas au Mexique et deux homologues privés : BASF Mexicana et Terminal de

Full Text Available Poured earth is a sustainable construction and economically feasible technique to develop in Tamaulipas, by the materials availability and traditional manufacturing procedures uses. There are several variables to be considered in these elements for their properties, among them it can be found roughness and porosity analysis which are important because they are related to material mechanical resistance and durability. This study aimed to characterize solid surfaces using fractal dimension to know its uniformity and porosity, compared with a concrete surface. Solids were obtained from poured earth of two combinations of soils stabilized with cement from the state of Tamaulipas. We found that a surface of a sample, obtained with ground, is more uniform than poured concrete surface, and that fractal dimension is higher while porosity increases; results suggest that this is because of the presence of clay in the poured earth mixtures. La tierra vertida es una técnica constructiva sustentable y económicamente viable para desarrollarse en Tamaulipas, por la disponibilidad de materiales y procedimientos de fabricación similares a los tradicionales. Son diversas las variables que deben estudiarse en estos elementos para conocer sus propiedades, entre las que se encuentran la rugosidad y la porosidad, las cuales son importantes debido a su estrecha relación con la resistencia mecánica y durabilidad del material estudiado. El presente trabajo tuvo por objetivo caracterizar superficies sólidas a partir de la dimensión fractal para conocer su uniformidad y porosidad, comparándola con una superficie de concreto. Los sólidos fueron obtenidos a partir de tierra vertida conformada de dos combinaciones de suelos estabilizadas con cemento provenientes del estado de Tamaulipas. Se encontró que una superficie de tierra vertida es menos irregular que una superficie de concreto además de tener una menor porosidad reflejada en una menor dimensión fractal

Commercial monocrystalline silicon (c-Si), polycrystalline silicon (p-Si) and amorphous silicon (a-Si) photovoltaic (PV) panels are tested on real conditions in order to identify which of the aforementioned PV panels present the best performance in the city of Altamira, Tamaulipas (northeastern Mexico) and to evaluate the impact of the city's climatic conditions over the electrical characteristics and power generation of the aforementioned PV panels. In situ direct solar irradiance and current-voltage characteristics (I-V) of each PV panel were taken from Monday to Friday at 11:00, 13:00 and 15:00 hours (GMT-6) with 3 repeats from 08/04/2014 to 07/31/2015. Also, daylong in situ direct solar irradiance, panel temperature, and I-V characteristics were taken from 8:00 to 20:30 hours with a 30-minute interval in synchrony with National Polytechnic Institute-owned CICATA-I meteorological station in order to cross-reference the experimental data with the station's air temperature, specific humidity and global solar irradiance data. Up to June 2015, c-Si panel presented the best performance on real conditions with mean max power loss of 49% compared to the reference max power value followed by the p-Si with 54% mean max power loss and the a-Si panel with a 73% mean max power loss. The number of cloudy days, electrical resistance due to panel materials nature and meteorological impact are further discussed.

medicamentos en el país, en general, y la disponibilidad de medicamentos esenciales en las unidades de primer nivel, en particular. Dos iniciativas de reciente puesta en marcha permiten ser optimistas al respecto: la descentralización de los servicios de salud para población no asegurada y el Programa de Medicamentos Genéricos Intercambiables, implantado en el ámbito nacional en 1998.OBJECTIVE: To describe the availability of some essential drugs at the primary health care units of the Ministry of Health of Tamaulipas, Mexico. MATERIAL AND METHODS: Between September and October 1998, all first level healthcare units of Tamaulipas' three sanitary jurisdictions were surveyed. Drug availability was assessed. The measurement instrument was a checklist of 56 drugs and 10 different supplies. For each drug and input the absolute number and the proportion of units with this drug or input was calculated. In the units where the drugs were available, the medians were calculated. The median of the total number of drugs available in all units was used as a global indicator. This same exercise was developed for each unit. Comparisons between the availability of these inputs in the units and stockrooms were also done. Stata 5.0 was used for statistical analysis. RESULTS: None of the inspected units had full availability of all checklist drugs. The highest percentage of drug availability was 84% and the lowest was 32%. There was limited availability of antibiotics, antihypertensive, hypoglycemic, and iron deficiency drugs. The availability of oral rehydration salts and contraceptive and vaccine agents was acceptable. CONCLUSIONS: Healthcare organizations must find alternative ways to improve access to drugs nationwide, in general, and availability of essential drugs in first level healthcare units, in particular. Two recent initiatives provide an optimistic outlook: decentralization of health services for the uninsured and the Generic Exchangeable Drugs Program, established nationwide in

This is a qualitative study. Participants were 24 adolescents with a body mass index equal to or greater than the 95th percentile. Semistructured interviews were conducted until data saturation was reached and the meaning was understood. The adolescents defined obesity according to standards of measurement. They identified the hereditary factor as the main obesity cause, tended to underestimate obesity and had low self-esteem. They reported problems to do physical exercise and get clothes in order to improve their image, and feel rejected by their peers in school. It was identified that these adolescents have psychological defense mechanisms against obesity and that some of them are making efforts to lose weight. Obesity entails social and psychological health implications for persons suffering from this problem. Interventions should be put in practice.El objetivo de esta investigación fue explorar las percepciones de la obesidad de adolescentes obesos estudiantes del 7º al 9º grado de una institución pública en Tamaulipas, México.

Full Text Available Diabetes mellitus is one the most progressive and fatal diseases in the world. Currently, more tan 346 million people suffer from diabetes around the world; Mexico has, according to its Ministry of Health, around 10 million people with this chronic degenerative disease. The Ministry of Health, in its adult and senior care program, has Mutual Help groups, where they and their relatives are offered self-management training. Activities are offered by staff from different health specialties, however, there is a low level in comprehension because of the way physicians express themselves. From the above, arises the need to implement individual and group communication techniques, that allow the patient and their relatives to learn what it takes to have an adequate self-care of diabetes mellitus.  This work is a study of the Mutual Help group of the Hospital Civil de Ciudad Victoria, in Tamaulipas, Mexico, where its members have this kind of talks. They consider necessary to change some of the strategies, to enable them to understand the self-management training processes taught by the health and medical staff, and therefore, their metabolic control.

Gonzalez, O D; Teyssier S, J

1967-08-01

The Tamaulipas-Constituciones Field is situated about 27 km from the city and port of Tampico, Mex., and is a part of the N. district, of the N. Development Zone of Petroleos Mexicanos. This article describes a method designed to calculate the recovery of oil by means of the application of a secondary recovery process based on the phenomenon of imbibition. The flow in the reservoir follows a system of fractures which are interconnected both in series, parallel, and randomly distributed. A more adequate method of development was determined than that which was enforced when the area wells started their initial production. Applying this method, 2 programs were developed; the first for an operation pressure of 125 kg per sq cm and the second for an operation pressure of 100 kg per cm. The production history is graphically represented. The characteristics of the reservoir are described, including the rock properties and the reservoir fluids. Complete information is furnished on the entire operation by means of tabular data. (15 refs.)

Conservation priorities for mammals in megadiverse Mexico: the efficiency of reserve networks.

Science.gov (United States)

Ceballos, Gerardo

2007-03-01

A major goal of conservation biologists is to identify critical areas for the conservation of biological diversity and then strategically include them in an efficient system of reserves. In general, however, reserve networks have been selected for different objectives, and most countries lack an evaluation of their reserves' ability to represent a percentage of the national diversity. This paper evaluates the effectiveness of a network of reserves to represent the species of mammals in Mexico. The focus of the analyses is on species and site level, evaluating the representation of all terrestrial mammals in the 30 most important reserves. The representation of all species, endemic species, endangered species, and species with restricted distributions in the reserves was assessed and compared. Endemic or endangered species with restricted distributions were expected to be less represented in reserves than were widespread species. The most important reserves for the conservation of mammals were determined with the use of complementarity analyses. Priority sites for the representation of all the species currently absent from the reserve network were then selected. The results have broad applications for conservation. First, 82% of the mammal species from Mexico were represented in the reserve network, which covers a small portion (3.8%) of the country. Second, this percentage is certainly larger as several reserves were not evaluated due to a lack of data. A priority for a national conservation strategy could be to conduct biological surveys in those reserves lacking inventories to evaluate their contribution to conservation. Third, in spite of its demonstrated value, Mexico's reserve network can be improved by designating complementary areas. Additional priority sites, where reserves are required to represent most gap species in the network, were identified. Finally, it is clear that this reserve network has limitations for maintaining biodiversity and ecosystem

Oil policies and privatization strategies in Mexico: implications for the petrochemical sector and its production spaces

International Nuclear Information System (INIS)

Laguna, N.M.

2004-01-01

Through a retrospective analysis of Mexico's oil history, this work examines the privatization processes that occurred in the petrochemical sector, from the abolishment of the government's monopoly, Petroleos Mexicanos (PEMEX) during the 1980s, until the restructuring and open liberalization in the early 1990s, focusing on the areas incorporated to production processes, particularly along the Gulf coast. As a result of the industrial policies and regional development strategies promoted by the government from the sixties, oriented towards strengthening production in areas with the highest potential, attractive business investment areas were developed. These included southern Tamaulipas, a strategic region where a number of industrial factors facilitated access to raw materials at competitive prices, as well as their processing and distribution to local and international markets, all of these within a single location. The strategic nature of the petrochemical location and production have made southern Tamaulipas a key factor for the territorial shaping and industrial development linked to the behavior of transnational companies that, seeking comparative advantages, have relocated parts of their production capacity in this region

Venezuelan equine encephalitis virus (VEEV) has been the causative agent for sporadic epidemics and equine epizootics throughout the Americas since the 1930s. In 1969, an outbreak of Venezuelan equine encephalitis (VEE) spread rapidly from Guatemala and through the Gulf Coast region of Mexico, reaching Texas in 1971. Since this outbreak, there have been very few studies to determine the northward extent of endemic VEEV in this region. This study reports the findings of serologic surveillance in the Gulf Coast region of Mexico from 2003–2010. Phylogenetic analysis was also performed on viral isolates from this region to determine whether there have been substantial genetic changes in VEEV since the 1960s. Based on the findings of this study, the Gulf Coast lineage of subtype IE VEEV continues to actively circulate in this region of Mexico and appears to be responsible for infection of humans and animals throughout this region, including the northern State of Tamaulipas, which borders Texas.

Full Text Available This article reviews the importance of gathering places in strengthening the primary social groups of individuals over the age of 15 years within six families in Matamoros, Tamaulipas. The relationship between primary social groups and spaces of social interaction is contextualized in an environment of insecurity fostered by the existence and violence of criminal groups who have managed to involve themselves in a range of significant activities in the city. Together with structural factors, insecurity has helped lead to a reconfiguration of gathering places between young people and adults; private and semi-public spaces predominate, while the intensive use of certain public spaces in the city has diminished.

Diabetic foot ulcers (DFUs) are a serious and common problem in patients with diabetes mellitus and constitute one of the major causes of lower extremity amputation. The microbiological profile of DFUs depends on the acute or chronic character of the wound. Aerobic gram-positive cocci are the predominant organisms isolated from DFUs. Diabetic foot biopsies from patients admitted to the Angiology and Vascular Surgery Hospital of the Northeast, in Reynosa, Tamaulipas from December 2011 to April 2016 were analyzed. The samples were processed using standard microbiology techniques. Antimicrobial susceptibility testing was carried out according to the protocol established by the Clinical & Laboratory Standards Institute (CLSI). We obtained 246 bacterial isolates, based on the results of phenotypic resistance. The least effective antibiotics for gram-positive bacteria were penicillin and dicloxacillin; for gram-negative bacteria, cefalotin and penicillin were the least effective. Levofloxacin, cefalotin, and amikacin were the most effective antibiotics for gram-positive and negative bacteria, respectively. Enterobacter genus was significantly associated with muscle biopsies ( P = .011) and samples without growth were significantly associated with specimens of pyogenic origin ( P = .000). In 215 DFU samples, we found that Staphylococcus aureus was the most commonly isolated pathogen followed by Enterobacter sp. This is consistent with previous reports. Enterobacter species may play an important role in the colonization/infection of certain tissues; however, further studies are needed in this regard.

The distribution range of the western pine beetle Dendroctonus brevicomis LeConte (Coleoptera: Curculionidae) is supported only by scattered records in the northern parts of Mexico, suggesting that its populations may be marginal and rare in this region. In this study, we review the geographical distribution of D. brevicomis in northern Mexico and perform a geometric morphometric analysis of seminal rod shape to evaluate its reliability for identifying this species with respect to other members of the Dendroctonus frontalis Zimmermann (Coleoptera: Curculionidae) complex. Our results provide 30 new records, with 26 distributed in the Sierra Madre Occidental and 4 in the Sierra Madre Oriental. These records extend the known distribution range of D. brevicomis to Durango and Tamaulipas states in northern Mexico. Furthermore, we find high geographic variation in size and shape of the seminal rod, with conspicous differences among individuals from different geographical regions, namely west and east of the Great Basin and between mountain systems in Mexico. © The Author 2017.

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).

The Mexican state of Nuevo Leon, located in the northeastern portion of the country, currently has 26 state and three federal nature reserves covering approximately 4.5% of its land area. These reserves were established for a variety of reasons not necessarily related to conservation purposes. In 2000 in response to a growing concern about the lack of organized conservation reserve planning to protect the important biological and physical features of Mexico, the Mexican Commission for Knowledge and Use of Biodiversity proposed 12 new terrestrial reserves for Nuevo Leon. The new reserves, if established, would increase the proportion of protected lands in the state to almost 24% of the state's land area. We compiled a Geographic Information System (GIS) analysis using digital thematic maps of physical and ecological features to examine how well the existing and proposed reserves incorporated the major biological and physical features of the state. The existing reserves are located primarily in regions with elevations > 1,000-1,500 m, on less productive soils, and are dominated by pine and oak forest cover types. As a result, the state's dominant biotic region - low elevation coastal plain with xeric scrub vegetation - is disproportionately under represented in the current reserve system. The new reserves would expand the protection of biophysical resources throughout the state. However, the inclusion of important resources in the low elevation coastal lands would still be limited.

Full Text Available Desde hace dos décadas los jornaleros tamaulipecos han recibido un considerable número de visas H-2A para trabajar en la agricultura en Estados Unidos. Los empleadores estadounidenses muestran una cierta preferencia por los jornaleros tamaulipecos, ya que la cercanía de Tamaulipas a la frontera disminuye los costos de transporte, que deben ser asumidos por los empleadores. Los programas de trabajadores huéspedes para mano de obra no cualificada exponen a los trabajadores foráneos al abuso y la explotación. La falta de cumplimiento con algunas regulaciones federales como el Estándar de Protección de los Trabajadores o el Seguro de Compensación Laboral incrementa el riesgo de envenenamiento por agroquímicos y accidentes entre los jornaleros, y aquellos que sufren accidentes laborales o enfermedades no reciben atención médica. Este artículo examina los problemas de salud sufridos por los trabajadores tamaulipecos empleados con visas H-2A en la agricultura estadounidense.From two decades ago Tamaulipas' farm workers have received a large amount of H-2A visas to work in the farming sector. U.S. farmers find it appealing to hire Tamaulipas' workers because of the proximity of Tamaulipas to the frontier, which lowers transportation costs, which have to be paid by the employers. It is well reported that low-skilled guest worker programs leaves foreign workforce open to abuse and exploitation. Poor compliance with federal regulations like the Worker Protection Standard and Workers Compensation Insurance increases the risk of pesticide poisoning and injuries among agricultural workers, and those who suffer work-related injuries or illnesses forgo needed medical care. This paper examines the health problems suffered by Tamaulipas's H-2A workers employed in U.S. agriculture.

Mexico currently has 144 nature reserves covering approximately 9.1% of its land area. These reserves were established for a variety of reasons - often unrelated to the protection of biodiversity. In 2000 in response to a growing concern about the lack of organized conservation reserve planning to protect the important threatened biological and physical features of Mexico, the Mexican Commission for Knowledge and Use of Biodiversity (CONABIO) proposed the establishment of 151 new reserves for Mexico covering 51,429,500 ha. We compiled a GIS analysis using digital thematic maps of physical and biological features to examine how the existing and proposed reserves serve to protect the biodiversity and physical features of the country. Using a conservation target of placing a minimum of 12% of the land area of each important biophysical feature in nature reserves, we found that the 144 existing nature reserves covering 18 million ha (9% of the country) only meet that target for elevation ranges >3000 m and areas with poor soils. These mountainous areas represent less than 1% of the country. The gaps in the existing nature reserves network occur mainly at lower and intermediate elevations (<3000 m) areas with xeric, tropical, and temperate ecosystems, and high productivity soils. The areas proposed by CONABIO increase the proportion of protected lands in the country to over 27% and most of the conservation targets for geophysical features, and land cover, categories are met. Whether this area would be sufficient to maintain viable populations and ecological integrity of species and ecosystems is unknown. Even with the new reserves, low elevation coastal lands would be below the conservation target in the nature reserves. To include a representative sample of these lands would be difficult as these are the same areas where the majority of people live. ?? 2003 Elsevier Ltd. All rights reserved.

Full text: We describe in this paper the results obtained by the project 'Radiological analysis of environmental samples in some points of the coast of the Gulf of Mexico and coast of Quintana Roo, Mexico'. The purpose of the study is to identify and quantify the natural and anthropogenic radionuclides present from sediments, sand and seawater from several sites located along the coast of the Gulf of Mexico and the Caribean Sea. The samples are analysed in a Canberra Multichannel analyzer system for gamma spectrometry, equipped with a detector of hyper pure germanium and a Genie 2000 software, in the 'Laboratory of Radiological Analysis of Environmental Samples', belonging to the Physics Department, Faculty of Sciences, National Autonomous University of Mexico (UNAM). The geographic sites were samples were taken include the states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan and Quintana Roo. The results of this studies will be published at the end of the project and we hope they will be useful for the national health and industrial sectors. Until now we have identified and measured the presence of natural radionuclides such as Potassium-40 (K-40), Bismuth 212 (Bi-212), Lead-212 (Pb-212), Bismuth-214 (Bi-214), Lead-214 (Pb-214), Radium-226 (Ra-226), Actinium 228 (Ac-228), Uranium-235 (U-235), as well as some anthropogenic radionuclides found near the Laguna Verde Nuclear Power Plant. The project is scheduled to last for three years, finishing in 2009. At its ending we shall be able to present conclusions and identify some tendencies, in connection with the background and possible radioactive contamination of the studied zones. This project takes place under the auspice of the 'Program of Support to Projects of Research and Technological Innovation' of the National Autonomous University of Mexico. (author)

Full Text Available The polymorphism of locus BoLA-DRB3.2 of the Major Histocompatibility Complex was evaluated in two northern Mexican Creole cattle populations, Chihuahua (n = 47 and Tamaulipas (n = 51. The BoLA-DRB3.2 locus was typed by amplification and digestion with restriction endonuclease enzymes (PCR-RFLP. Fifty-two alleles were detected (28 previously reported and 24 new ones. In the Chihuahua population, 18 alleles and 5.5 effective alleles were found, while in the Tamaulipas population there were 34 and 10.8, respectively. The allele frequencies ranged from 0.011 to 0.383 in Chihuahua and from 0.010 to 0.206 in Tamaulipas. The frequencies of the new alleles in both cattle populations were low (0.010 to 0.053. The expected heterozygosity was 0.827 and 0.916, respectively, for the Chihuahua and Tamaulipas populations. Both populations presented a heterozygote deficit: [Chihuahua F IS = 0.1 (p = 0.019 and Tamaulipas F IS = 0.317 (p < 0.001]. In conclusion, this study showed that the Mexican Creole cattle have many low-frequency alleles, several of which are exclusive to these populations. Genetic distances obtained show that the Mexican Creole cattle population is composed of independent populations, far apart from other South American Creole populations.

A dengue-2 epidemic causing dengue hemorrhagic fever (DHF) occurred in the contiguous border cities of Matamoros, Tamaulipas (Mexico), and Brownsville, TX, in 2005. In December, we conducted a household-based epidemiologic survey to determine the incidence and seroprevalence of dengue infection among Matamoros and Brownsville residents and to identify risk factors associated with infection. Antibodies to dengue were measured in 273 individuals. The estimated incidence of recent dengue infection was 32% and 4% among Matamoros and Brownsville participants, respectively. The estimated prevalence of past dengue infection was 77% and 39% among Matamoros and Brownsville participants, respectively. The Breteau index was 28 in Matamoros and 16 in Brownsville, reflecting an abundant winter population of Aedes mosquitoes. Discarded waste tires and buckets were the two largest categories of infested containers found in both cities. Our results underscore the risk for epidemic dengue and DHF in the Texas-Mexico border region.

2009-12-01

On the 23th of May 2007 at 14:09 local time (19:09 UT) an insolated earthquake of local magnitude 5.2 occurred offshore northern Veracruz in the Gulf of Mexico. The seismic focus was located using local and regional data at 20.11° N, 97.38° W and 7.8 km depth at 175 km distance from Tuxpan a city of 134,394 inhabitants. The earthquake was widely felt along the costal states of southern Tamaulipas and Veracruz in which several schools and public buildings were evacuated. Neither Laguna Verde nuclear plant, located approximately 245 km from the epicenter, nor PEMEX petroleum company reported damage. First-motion data indicates that the rupture occurred as strike slip faulting along two possible planes, one oriented roughly north-south and the other east-west. In the present paper a global analysis of the earthquake is made to elucidate its origin and possible correlation with known geotectonic features of the region.

For many marine species, locations of migratory pathways are not well defined. We used satellite telemetry and switching state-space modeling (SSM) to define the migratory corridor used by Kemp's ridley turtles (Lepidochelys kempii) in the Gulf of Mexico. The turtles were tagged after nesting at Padre Island National Seashore, Texas, USA from 1997 to 2014 (PAIS; n = 80); Rancho Nuevo, Tamaulipas, Mexico from 2010 to 2011 (RN; n = 14); Tecolutla, Veracruz, Mexico from 2012 to 2013 (VC; n = 13); and Gulf Shores, Alabama, USA during 2012 (GS; n = 1). The migratory corridor lies in nearshore Gulf of Mexico waters in the USA and Mexico with mean water depth of 26 m and a mean distance of 20 km from the nearest mainland coast. Migration from the nesting beach is a short phenomenon that occurs from late-May through August, with a peak in June. There was spatial similarity of post-nesting migratory pathways for different turtles over a 16 year period. Thus, our results indicate that these nearshore Gulf waters represent a critical migratory habitat for this species. However, there is a gap in our understanding of the migratory pathways used by this and other species to return from foraging grounds to nesting beaches. Therefore, our results highlight the need for tracking reproductive individuals from foraging grounds to nesting beaches. Continued tracking of adult females from PAIS, RN, and VC nesting beaches will allow further study of environmental and bathymetric components of migratory habitat and threats occurring within our defined corridor. Furthermore, the existence of this migratory corridor in nearshore waters of both the USA and Mexico demonstrates that international cooperation is necessary to protect essential migratory habitat for this imperiled species.

Full Text Available Species vulnerability is increased when individuals congregate in restricted areas for breeding; yet, breeding habitats are not well defined for many marine species. Identification and quantification of these breeding habitats are essential to effective conservation. Satellite telemetry and switching state-space modeling (SSM were used to define inter-nesting habitat of endangered Kemp's ridley turtles (Lepidochelys kempii in the Gulf of Mexico. Turtles were outfitted with satellite transmitters after nesting at Padre Island National Seashore, Texas, USA, from 1998 through 2013 (n = 60; Rancho Nuevo, Tamaulipas, Mexico, during 2010 and 2011 (n = 11; and Tecolutla, Veracruz, Mexico, during 2012 and 2013 (n = 11. These sites span the range of nearly all nesting by this species. Inter-nesting habitat lies in a narrow band of nearshore western Gulf of Mexico waters in the USA and Mexico, with mean water depth of 14 to 19 m within a mean distance to shore of 6 to 11 km as estimated by 50% kernel density estimate, α-Hull, and minimum convex polygon methodologies. Turtles tracked during the inter-nesting period moved, on average, 17.5 km/day and a mean total distance of 398 km. Mean home ranges occupied were 725 to 2948 km2. Our results indicate that these nearshore western Gulf waters represent critical inter-nesting habitat for this species, where threats such as shrimp trawling and oil and gas platforms also occur. Up to half of all adult female Kemp's ridleys occupy this habitat for weeks to months during each nesting season. Because inter-nesting habitat for this species is concentrated in nearshore waters of the western Gulf of Mexico in both Mexico and the USA, international collaboration is needed to protect this essential habitat and the turtles occurring within it.

[Historical presence of invasive fish in the biosphere reserve sierra de Huautla, Mexico].

The effects of invasive species on native ecosystems are varied, and these have been linked to the disappearance or decline of native fauna, changes in community structure, modification of ecosystems and as vectors of new diseases and parasites. Besides, the development of trade in species for ornamental use has contributed significantly to the import and introduction of invasive fish in some important areas for biodiversity conservation in Mexico, but the presence of these species is poorly documented. In this study we analyzed the fish community in the Biosphere Reserve Sierra de Huautla by looking at diversity changes in the last 100 years. For this, we used databases of historical records and recent collections for five sites in the Amacuzac river, along the Biosphere Reserve area. We compared the values of similarity (Jaccard index) between five times series (1898-1901, 1945-1953, 1971-1980, 1994-1995 and 2008-2009), and we obtained values of similarity (Bray-Curtis) between the five sites analyzed. In our results we recognized a total of 19 species for the area, nine non-native and ten native, three of which were eliminated for the area. Similarity values between the early days and current records were very low (.27); the major changes in the composition of the fauna occurred in the past 20 years. The values of abundance, diversity and similarity among the sampling sites, indicate the dominance of non-native species. We discuss the role of the ornamental fish trade in the region as the leading cause of invasive introduction in the ecosystem and the possible negative effects that at least four non-native species have had on native fauna and the ecosystem (Oreochromis mossambicus, Amatitlania nigrofasciata, Pterygoplichthys disjunctivus and P pardalis). There is an urgent need of programs for registration, control and eradication of invasive species in the Sierra de Huautla Biosphere Reserve and biodiversity protection areas in Mexico.

Full Text Available The suicide has existed throughout history and has prevailed as a behavior that was contrary to the rules of the society in terms of preservation of life itself; the objective of this research was to make emphasis on the nature of antisocial behavior of this behavior and show its prevalence in the years 2006 to 2010 in Mexico and Tamaulipas, as well as from 1999 to 2008 in Reynosa, Tamaulipas. For which the data were obtained from the National Institute of Statistics and Geography to the country and the State and the books of the register of deaths by cause violent of the Regional Unit of Expert Services of the Attorney General of Justice, which has its headquarters in Reynosa; developed a theoretical framework on the impact of the conduct in society and the means to prevent it, The data obtained we revealed the continued presence of this conduct year-on-year, 23.554 cases appearing in Mexico and 819 in Tamaulipas in the period from 2006 to 2010; in Reynosa, Tamaulipas were presented 278 suicides in the period 1999 to 2008. The results show us a conduct stable in numbers, but without excessive overflows that prevails year-on-year, suicide, and the attempt of the same should be viewed as a social problem and not detract from the importance that it deserves a conduct of these dimensions, that is no more than a reflection of the situation in which are the means of social control toward the preservation of life itself.

The protozoan Perkinsus marinus (Mackin, Owen & Collier) Levine, 1978 causes perkinsosis in the American oyster Crassostrea virginica Gmelin, 1791. This pathogen is present in cultured C. virginica from the Gulf of Mexico and has been reported recently in Saccostrea palmula (Carpenter, 1857), Crassostrea corteziensis (Hertlein, 1951) and Crassostrea gigas (Thunberg, 1793) from the Mexican Pacific coast. Transportation of fresh oysters for human consumption and repopulation could be implicated in the transmission and dissemination of this parasite across the Mexican Pacific coast. The aim of this study was two-fold. First, we evaluated the P. marinus infection parameters by PCR and RFTM (Ray's fluid thioglycollate medium) in C. virginica from four major lagoons (Términos Lagoon, Campeche; Carmen-Pajonal-Machona Lagoon complex, Tabasco; Mandinga Lagoon, Veracruz; and La Pesca Lagoon, Tamaulipas) from the Gulf of Mexico. Secondly, we used DNA sequence analyses of the ribosomal non-transcribed spacer (rNTS) region of P. marinus to determine the possible translocation of this species from the Gulf of Mexico to the Mexican Pacific coast. Perkinsus marinus prevalence by PCR was 57.7% (338 out of 586 oysters) and 38.2% (224 out of 586 oysters) by RFTM. The highest prevalence was observed in the Carmen-Pajonal-Machona Lagoon complex in the state of Tabasco (73% by PCR and 58% by RFTM) and the estimated weighted prevalence (WP) was less than 1.0 in the four lagoons. Ten unique rDNA-NTS sequences of P. marinus [termed herein the "P. marinus (Pm) haplotype"] were identified in the Gulf of Mexico sample. They shared 96-100% similarity with 18 rDNA-NTS sequences from the GenBank database which were derived from 16 Mexican Pacific coast infections and two sequences from the USA. The phylogenetic tree and the haplotype network showed that the P. marinus rDNA-NTS sequences from Mexico were distant from the rDNA-NTS sequences of P. marinus reported from the USA. The ten r

Se empleó un diseño de estudio de caso intrínseco, y se realizaron entrevistas semiestructuradas para aproximarse al proceso deconstrucción de su representación social. Para analizar el contenido temático se utilizó el programa MAXQDA 11. Los resultados muestran que los adolescentes consideran al narcotráfico como una actividad delictiva, que se ha diversificado para incluir otros delitos asociados con la violencia y el daño a los demás. Es un estudio exploratorio y, pese al número reducido de participantes, recupera las voces de los adolescentes inmersos en comunidades donde hay narcotráfico, sin que participen directamente en él, también da cuenta de que la incorporación de los jóvenes en el narcotráfico se limita cuando lo perciben como un delito, y elaboran su identidad en contraposición a él.

Uranium exploration, mining and milling proposal, Navajo Indian Reservation, New Mexico

International Nuclear Information System (INIS)

Babby, W.D.

1974-01-01

The Secretary of the Interior has been requested to approve an exploration permit and mining lease which are part of a uranium exploration, mining, and milling Agreement, negotiated between the Navajo Tribe and the Exxon Corporation. The exploration area is a 400,000 acre tract located on the Navajo Reservation in San Juan County, New Mexico. If uranium ore in sufficient quantities to warrant development is discovered, Exxon is authorized to take a total of 51,200 acres to lease for mining, of which only 5,120 surface acres may be used for mining and milling purposes. While all exploration and predevelopment costs prior to mining must be borne by Exxon, the Navajo Tribe has reserved the right to participate in the venture on either a royalty basis or as a partner holding up to a 40 percent working interest. Impacts resulting from exploration will include disturbance of soils and vegetation and air quality degradation resulting from the vehicular movement and the operation of drilling equipment. If mining and milling takes place significant environmental impacts include: sub-surface water depletion, soils and vegetation disturbance, air quality degradation, interruption of the wildlife habitat, population increases, increased demands on community services and facilities, and disruption of established lifestyles and social patterns. Low levels of radioactive emissions will be found at mine and mill sites. Income and employment opportunities from the project to the Navajo Tribe, Navajo people, and the entire San Juan County community will be significant

We used aerial photographs, satellite images, and field surveys to monitor forest cover in the core zones of the Monarch Butterfly Biosphere Reserve in Mexico from 2001 to 2012. We used our data to assess the effectiveness of conservation actions that involved local, state, and federal authorities and community members (e.g., local landowners and private and civil organizations) in one of the world's most iconic protected areas. From 2001 through 2012, 1254 ha were deforested (i.e., cleared areas had <10% canopy cover), 925 ha were degraded (i.e., areas for which canopy forest decreased), and 122 ha were affected by climatic conditions. Of the total 2179 ha of affected area, 2057 ha were affected by illegal logging: 1503 ha by large-scale logging and 554 ha by small-scale logging. Mexican authorities effectively enforced efforts to protect the monarch reserve, particularly from 2007 to 2012. Those efforts, together with the decade-long financial support from Mexican and international philanthropists and businesses to create local alternative-income generation and employment, resulted in the decrease of large-scale illegal logging from 731 ha affected in 2005-2007 to none affected in 2012, although small-scale logging is of growing concern. However, dire regional social and economic problems remain, and they must be addressed to ensure the reserve's long-term conservation. The monarch butterfly (Danaus plexippus) overwintering colonies in Mexico-which engage in one of the longest known insect migrations-are threatened by deforestation, and a multistakeholder, regional, sustainable-development strategy is needed to protect the reserve. © 2013 Society for Conservation Biology.

To examine physical and mental health domains of health-related quality of life (HRQL) in a binational adult population with type 2 diabetes at the Texas-Mexico border, and to explore individual and social correlates to physical and mental health status. Adults 18 years and older with type 2 diabetes residing in the South Texas Lower Rio Grande Valley and in Reynosa, Tamaulipas, Mexico, were recruited using a convenience sampling technique and interviewed face-to-face with a structured survey. HRQL was measured using physical and mental health summary components of the Medical Outcomes Study Short Form. HRQL correlates included demographic characteristics, health factors, access to healthcare, and family support. Samples characteristics were compared using the Student's t-test or Mann-Whitney U test. Associations between dependent and independent variables were examined using unadjusted and adjusted (multiple variable) logistic regression models. There were no significant differences between Valley and Reynosa respondents in physical or mental health status scores. Valley participants with lower socioeconomic status and those perceiving their supportive relative's level of diabetes-related knowledge as "low" were more likely to report worse physical health than those lacking those characteristics. In the Reynosa group, lower physical health status was associated with duration of diabetes and insulin use. Both sample populations with clinical depressive symptoms were more likely to have worse physical and mental health than those without such symptoms. HRQL is an important outcome in monitoring health status. Understanding the levels and influences of HRQL in U.S.-Mexico border residents with diabetes may help improve diabetes management programs.

Spatial and temporal land cover changes in Terminos Lagoon Reserve, Mexico.

Soto-Galera, Ernesto; Piera, Jaume; López, Pilar

2010-06-01

Terminos Lagoon ecosystem is the largest fluvial-lagoon estuarine system in the country and one of the most important reserves of coastal flora and fauna in Mexico. Since the seventies, part of the main infrastructure for country's oil extraction is located in this area. Its high biodiversity has motivated different type of studies including deforestation processes and land use planning. In this work we used satellite image analysis to determine land cover changes in the area from 1974 to 2001. Our results indicate that tropical forest and mangroves presented the most extensive losses in its coverage. In contrast, urban areas and induced grassland increased considerably. In 2001 more than half of the ecosystem area showed changes from its original land cover, and a third part of it was deteriorated. The main causes of deforestation were both the increase in grassland and the growth of urban areas. However, deforestation was attenuated by natural reforestation and plant canopy recovery. We conclude that the introduction of cattle and urban development were the main causes for the land cover changes; however, the oil industry activity located in the ecosystem, has promoted indirectly to urban growth and rancher boom.

2010-03-01

Full Text Available The impact of ecotourism on the Natural Reserve Agua Selva, Mexico, was assessed. Changes of land use in the forest were evaluated.  An analysis of some socio-economic and cultural changes in the community since ecotourism was introduced was carried out. The perception of villagers towards ecotourism is also presented. The analysis was made with satellite images landsat type (sensor MSS and TM obtained in 1976 and 2000. Cartography and farm plots were also used for the analysis of land use changes. Socio-economic changes were analyzed based on questionnaires and semi-structured interviews. The introduction of ecotourism in the area of study had both positive and negative effects. Although ecotourism did not reverse the deforestation processes, the general deforestation rate was 0.49%. This is smaller to reports in literature for other zones in Tabasco with similar characteristics in the same period of time.  It was found that there was a positive change of Villager’s attitudes towards ecotourism in the last 15 years. This is mainly because this activity is a source of income and has become progressively more important compared to other rural economic activities. It was found that the community participation is scarce and thus has caused problems in the management of specific projects. The results of this research suggest that the success of ecotourism in Agua Selva depends on the integration of ecotourism with the other agricultural and social programs implemented in the area. Implementing agricultural development programs not linked to ecotourism activities can lead to deforestation which is the reserve’s main attraction.

Full Text Available Diseases are of particular importance for aquaculture worldwide, particularly in intensive culture. In Mexico, intensive culture of channel catfish is mainly done in floating cages. The aim of the present study was to determine the presence of the myxozoan Henneguya and the effect of site, period and host length on its prevalence in cage-cultured channel catfish. Over a year, fish were examined on six different sites. Results showed the presence of Henneguya exilis in all the farms. However, no significant effects were observed for site and season on prevalence, nor was there a correlation between host length and infection prevalence.

Rural aquaculture as a sustainable alternative for forest conservation in the Monarch Butterfly Biosphere Reserve, Mexico.

Science.gov (United States)

López-García, José; Manzo-Delgado, Lilia L; Alcántara-Ayala, Irasema

2014-06-01

Forest conservation plays a significant role in environmental sustainability. In Mexico only 8.48 million ha of forest are used for conservation of biodiversity. Payment for Environmental Services in the Monarch Butterfly Biosphere Reserve, one of the most important national protected areas, contributes to the conservation of these forests. In the Reserve, production of rainbow trout has been important for the rural communities who need to conserve the forest cover in order to maintain the hibernation cycle of the butterfly. Aquaculture is a highly productive activity for these protected areas, since it harnesses the existing water resources. In this study, changes from 1999 to 2012 in vegetation and land-use cover in the El Lindero basin within the Reserve were evaluated in order to determine the conservation status and to consider the feasibility of aquaculture as a means of sustainable development at community level. Evaluation involved stereoscopic interpretation of digital aerial photographs from 1999 to 2012 at 1:10,000 scale, comparative analysis by orthocorrected mosaics and restitution on the mosaics. Between 1999 and 2012, forested land recovered by 28.57 ha (2.70%) at the expense of non-forested areas, although forest degradation was 3.59%. Forest density increased by 16.87%. In the 46 ha outside the Reserve, deforestation spread by 0.26%, and land use change was 0.11%. The trend towards change in forest cover is closely related to conservation programmes, particularly payment for not extracting timber, reforestation campaigns and surveillance, whose effects have been exploited for the development of rural aquaculture; this is a new way to improve the socio-economic status of the population, to avoid logging and to achieve environmental sustainability in the Reserve.

Sexual competitiveness and compatibility between mass-reared sterile flies and wild populations of Anastrepha Ludens (Diptera: Tephritidae) from different regions in Mexico

International Nuclear Information System (INIS)

Orozco-Davila, D.; Hernandez, R.; Meza, S.; Dominguez, J.

2007-01-01

The mass-reared colony of Anastrepha ludens (Loew) currently used in Mexico for suppression of the Mexican fruit fly has been in use for over 10 years. Sterile flies are released into a wide range of environmental conditions as part of an integrated area-wide approach to suppress diverse populations of this pest in the Mexican Republic. This paper assesses the performance of the sterile flies interacting with wild populations from the different environments. We investigated the sexual compatibility and competitiveness of the sterile flies when competing with wild populations from 6 representatives Mexican states: Nuevo Leon, Tamaulipas, Sinaloa, Nayarit, Michoacan, and Chiapas. Results show that the males of the wild populations differed in the time to the onset and peak of sexual activity. Nevertheless, the index of sexual isolation (ISI) reflected sexual compatibility between the populations and the mass-reared strain, indicating that the sterile individuals mate satisfactorily with the wild populations from the 6 states. The male relative performance index (MRPI) showed that the sterile male is as effective in copulating as the wild males. The female relative performance index (FRPI) reflected a general tendency for wild females to copulate in greater proportion than the sterile females, except for the strains from Tamaulipas and Chiapas. In general, the lower participation of the sterile females in copulation increases the possibilities of sterile males to mate with wild females. The relative sterility index (RSI) showed that the acceptance by wild females of the sterile males (25-55%) was similar to that of wild males. Females of the Chiapas strain showed the lowest acceptance of sterile males. Finally, the results obtained in the Fried test (which measures induced sterility in eggs) showed a competitiveness coefficient ranging from 0.2 to 0.5. This suggests that sterile males successfully compete and are compatible with flies from different geographic origins

2013-11-01

Full Text Available One of the major current challenges in the livestock industry is meeting the demand for livestock products of a growing world population. Bio-economic models integrate animal biology and rural enterprise management, which allows for the study of complex animal production systems. This paper aims at simulating the productive performance of a herd grazing under different management conditions. To do so, a simple simulation model of a goat herd (MSSRC, rangeland forage growth, and the dynamics of animal population in the semi-arid region of Southwestern Tamaulipas under three rainfall scenarios (300, 500, and 700 mm. of average annual precipitation was built. The objective was to evaluate the sustainability of extensive grazing under different animal loads. Nine different scenarios were evaluated, corresponding to the different combinations of the three rainfall scenarios and three levels of initial loads (Hi and nannies maximum load (HMAX. Evaluated variables are: kids sales (C; total number of nannies (female goats, HT; sales of replacement nannies (VREE; sales of scrap goats (CDS; rangeland condition (CA; voluntary consumption (CV; mortality rate (M; abortion rate (A;  and average annual profits (UPA. Simulation was performed on a 1,000 hectares plot, and three 10-year periods were used as time framework. Analysis of Variance (ANOVA revealed statistically significant (P < 0.05 differences between scenarios for all studied variables. Biomass primary net production under the 300, 500, and 700 mm of rainfall was found to be 1,132.2 ± 362.9, 2,244.2 ± 517.0, and 3,113.3 ± 598.7 kg DM ha-1 per year, and the average annual production of kids was 36 ± 17, 90 ± 31, and 132 ±37, respectively. The low loads scenarios showed a stable behavior, with a constant rate of kids production over the three simulation periods (0-30 years, which resulted in a higher average annual profit, and a more sustainable profile than those with heavier

1996-01-01

Hydrocarbon reserves in Mexico, ranked 8th in the world, were discussed. On January 1, 1996, Mexico's hydrocarbon proven reserves were 62.1 billion barrels ( a decline of some 10 billion barrels since 1984). Of this 48.8 billion corresponded to crude oil and 13.3 billion to natural gas. Mexico's natural gas pipeline network includes 10,280 kilometres in transmission and 2,211 kilometres in distribution, concentrated along the Gulf of Mexico and in the central and northern regions of the country. A new regulatory framework for natural gas, passed in Congress in 1995, was outlined. The new amendments were designed to strengthen the natural gas industry through private investment in the storage, transportation and distribution of natural gas. Stages for third party access were identified. Increased North American regional integration by interconnections between Mexican, American and Canadian pipeline networks, and the effects of such integration on investments, were examined. figs

Uranium resources in New Mexico

McLemore, V.T.; Chenoweth, W.L.

1989-01-01

For nearly three decades (1951-1980), the Grants uranium district in northwestern New Mexico produced more uranium than any other district in the world. The most important host rocks containing economic uranium deposits in New Mexico are sandstones within the Jurassic Morrison Formation. Approximately 334,506,000 lb of U 3 O 8 were produced from this unit from 1948 through 1987, accounting for 38% of the total uranium production from the US. All of the economic reserves and most of the resources in New Mexico occur in the Morrison Formation. Uranium deposits also occur in sandstones of Paleozoic, Triassic, Cretaceous, Tertiary, and Quaternary formations; however, only 468,680 lb of U 3 O 8 or 0.14% of the total production from New Mexico have been produced from these deposits. Some of these deposits may have a high resource potential. In contrast, almost 6.7 million lb of U 3 O 8 have been produced from uranium deposits in the Todilto Limestone of the Wanakah Formation (Jurassic), but potential for finding additional economic uranium deposits in the near future is low. Other uranium deposits in New Mexico include those in other sedimentary rocks, vein-type uranium deposits, and disseminated magmatic, pegmatitic, and contact metasomatic uranium deposits in igneous and metamorphic rocks. Production from these deposits have been insignificant (less than 0.08% of the total production from New Mexico), but there could be potential for medium to high-grade, medium-sized uranium deposits in some areas. Total uranium production from New Mexico from 1948 to 1987 amounts to approximately 341,808,000 lb of U 3 O 8 . New Mexico has significant uranium reserves and resources. Future development of these deposits will depend upon an increase in price for uranium and lowering of production costs, perhaps by in-situ leaching techniques

Mosquito collections were conducted during a dengue outbreak in Reynosa, Tamaulipas, Mexico, July-December 1995. A total of 6694 adult mosquitoes (four genera and nine species) were captured, of which 2986 (78.3% females and 21.7% males) were Aedes albopictus and 2339 (39.7% females and 60.3% males) were Ae.aegypti. These two species comprised 84.2% of the total collection. Specimens were grouped into pools, nearly 50% of them processed for detection of virus by cythopathic effect in C6-36 and VERO cell cultures and by haemagglutination test. Five pools gave positive haemagglutination reactions and were examined by immunofluorescence using monoclonal antibodies to flavivirus and to dengue virus. One pool of ten Ae.albopictus males was positive for dengue virus: serotypes 2 and 3 were identified by serotype-specific monoclonal antibodies and confirmed by RT-PCR. This is the first report of Ae.albopictus naturally infected with dengue virus in America. Also, it is the very first time Ae.albopictus males have been found infected with dengue virus in the wild.

This study examines urban pollution within Derechos Humanos, a colonia popular in Matamoros, Tamaulipas, Mexico. General water quality indicators (coliform bacteria, total dissolved solids, ecologically relevant cations and anions), heavy metals (copper, lead, nickel, zinc, iron and cadmium), and volatile organic compounds (benzene, toluene, ethylbenzene, styrene, and dichlorobenzene and xylene isomers) were quantified within a wastewater canal running adjacent to the community. Water samples were collected at multiple sites along the banks of the canal and evidence of anthropogenic emissions existed at each sampling location. Sample site 2, approximately 10 m upstream of the colonia, contained both the widest range of hazardous pollutants and the greatest number exceeding US Environmental Protection Agency surface water standards. At each sampling location, high concentrations of total coliform (>10{sup 4} colonies/100 mL sample), lead (ranging from 0.05 to 0.40 mg/L), nickel (levels from 0.21 to 1.45 mg/L), and benzene (up to 9.80 mg/L) were noted. - This study quantifies widespread industrial and urban contamination within a canal located in a colonia (unplanned community) in Matamoros, Tamaulipas on the US-Mexico border.

Entomopathogenic fungi were isolated and identified from insects collected from the tropical forest and an agricultural area at El Eden Ecological Reserve, Quintana Roo, Mexico. These fungi were studied to determine their potential as biological control agents of greenhouse Trialeurodes vaporariorum (Homoptera: Aleyrodidae), and to contribute to the knowledge of biodiversity of this area. No pest insects were observed in the tropical forest. In contrast, all insects collected in the agricultural area were considered important pests by the local farmers, with the whitefly, as the most relevant, plentiful in Cucurbitaceae plants. From approximately 3400 collected insects in three different surveys, different anamorphic Ascomycetes were recovered. One isolate of Aspergillus sp., two of Penicillium sp., three of Paecilomyces marquandii, and three of Verticillium sp. out of 308 insects (2.9%) from three insect orders, Hymenoptera, Diptera and Isoptera in the tropical forest. In contrast, a higher number of fungal isolates were recovered from the agricultural area: three isolates from Aspergillus parasiticus, 100 of Fusarium moniliforme, one of Aschersonia sp., and 246 of Fusarium oxysporum out of 3100 insects (11.3%) from three insect orders, Homoptera, Coleoptera and Lepidoptera. The results of this study show Fusarium moniliforme and F oxysporum as highly virulent to infected insects in the agricultural area, with 100 and 246 isolates respectively, out of 350 infected insects of 3100 studied specimens. Laboratory whitefly nymph bioassays with isolates Ed29a of F. moniliforme, Ed322 of F. oxysporum, and Ed22 of P marquandii showed 96 to 97.5% insect mortality with no significant differences (P < 0.05) among them. F. oxysporum Ed322 produced no mortality when inoculated on tomato, bean, squash and maize seedlings (with and without injuries) compared to the 100% mortality caused by phytopathogenic strains, F. oxysporum f. sp. lycopersici and F. oxysporum f. sp. radicis

We analyzed a total of 70 grilled chicken samples bought randomly from street vendors and retail outlets in the city of Reynosa, Mexico, to determine the prevalence of Escherichia coli (Shiga toxin producing and enterotoxin producing), Salmonella spp., Staphylococcus aureus, Listeria spp., and Campylobacter spp. using microbiological methods and PCR detection of bacterial sequences. Of the 70 samples, 27 (38.5%) were from retail outlets and 43 (61.4%) from street vendors. All specimens were negative by both microbiological and molecular methods for Listeria monocytogenes, Shiga toxin 2 of Shiga toxin-producing E. coli, lt of enterotoxin-producing E. coli, and st enterotoxin, and all were negative for Salmonella spp. and Campylobacter jejuni by PCR. Of the samples studied, 49 (70%) had undetectable levels of the foodborne pathogens studied with the methods used. In the remaining 21 (30%) specimens, at least one pathogen was isolated or detected, with E. coli being the pathogen most frequently isolated and with two samples bearing the hlyA gene. We found no statistical difference in bacterial prevalence between retail and street vendor samples. The presence of pathogens in grilled chicken is an important public health risk because of the great demand for and daily consumption of this product in this region.

We evaluated the relationship between limnetic characteristics and fish community structure (based on species richness, abundance and individual size) in contrasting but interconnected inland aquatic habitats of freshwater karstic wetlands in the Yucatan peninsula, Mexico. In the western hemisphere, freshwater karstic wetlands are found in south-eastern Mexico, northern Belize, western Cuba, Andros Island, Bahamas and the Everglades of southern Florida. Only in the Everglades have fish communities been well described. Karstic wetlands are typically oligotrophic because calcium carbonate binds phosphorus, making it relatively unavailable for plants. Fourteen permanent and seasonally flooded water bodies were sampled in both wet and dry seasons in Sian Ka'an Biosphere Reserve, in the Mexican state of Quintana Roo. Water systems were divided by morphology in four groups: cenotes with vegetation (CWV), cenotes without vegetation (CNV), wetlands (WTL), and temporal cenotes (TPC). Discriminant analysis based on physical characteristics such as turbidity, temperature, depth and oxygen confirmed that these habitats differed in characteristics known to influence fish communities. A sample-based rarefaction test showed that species richness was significantly different between water systems groups, showing that WTL and CWV had higher richness values than CNV and TPC. The most abundant fish families, Poeciliidae, Cichlidae and Characidae, differed significantly in average size among habitats and seasons. Seasonal and inter-annual variation, reflecting temporal variation in rainfall, strongly influenced the environmental differences between shallow and deep habitats, which could be linked to fish size and life cycles. Five new records of species were found for the reserve, and one new record for Quintana Roo state. ?? 2006 by Verlag Dr. Friedrich Pfeil.

Uranium - raw material reserves for coming generations

1981-01-01

Large uranium occurences have been discovered in the South of Mexico. The deposits are situated in the Sierra Mixteca. Reserves of 9.400 tons had been at Mexico's disposal even before these new discoveries. The quantitiy discovered recentyl amounts to 20.000 tons. The uranium reserves available apart from those in centrally controlled economic systems are presently estimated at five million tons. Meanwhile American scientists have found out that all the rivers of the world transport about 16.000 tons of uranium from the continents into the oceans per annum. The energy value of this washed out amount of uranium corresponds to the 25-fold world power demand of today. US scientists have discovered that the oceans can provide uranium for about seven million years of the present world energy demand. While the petroleum reserves decrease worldwide it seems that the exploration of uranium has just been started. (orig.) [de

Pathogenic landscape of transboundary zoonotic diseases in the Mexico-US border along the Rio Grande

Full Text Available 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 millions of people live in this transboundary region but also a substantial movement 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.

Territorialisation, Conservation, and Neoliberalism in the Tehuacán-Cuicatlán Biosphere Reserve, Mexico

Alison Elizabeth Lee

2014-01-01

Full Text Available The territorialisation of a botanical garden and the Tehuacán-Cuicatlán Biosphere Reserve (TCBR in southern Mexico is examined from the perspective of local residents of one rural town and the biologists whose professional careers involved extensive research in the region. While there were brief periods of conflict between residents and outsiders over the use of local lands for conservation, the cumulative effects demonstrate a general acceptance of the conservation paradigm. Local residents re-appropriated an older discourse linking their land rights to indigenous ancestors in order to mobilise collective support to ensure local control of the botanical garden. The discourse was subsequently incorporated into a local ecotourism project providing cultural substance complementary to the biological and visual aspects of the landscape. Contradictions between conservation and livelihoods were minimal due to neoliberal policies that encouraged migration to the United States of America and wage work in regional maquiladoras. Consequently, the territorialisation of conservation spaces was not disruptive to the increasingly proletarianised, non-agricultural livelihoods of local residents.

Mezcal is an alcoholic beverage obtained from the distillation of fermented juices of cooked Agave spp. plant stalks (agave must), and each region in Mexico with denomination of origin uses defined Agave species to prepare mezcal with unique organoleptic characteristics. During fermentation to produce mezcal in the state of Tamaulipas, not only alcohol-producing yeasts are involved, but also a lactic acid bacterial community that has not been characterized yet. In order to address this lack of knowledge on this traditional Mexican beverage, we performed a DGGE-16S rRNA analysis of the lactic acid bacterial diversity and metabolite accumulation during the fermentation of a typical agave must that is rustically produced in San Carlos County (Tamaulipas, Mexico). The analysis of metabolite production indicated a short but important malolactic fermentation stage not previously described for mezcal. The denaturing gradient gel electrophoresis (DGGE) analysis of the 16S rRNA genes showed a distinctive lactic acid bacterial community composed mainly of Pediococcus parvulus, Lactobacillus brevis, Lactobacillus composti, Lactobacillus parabuchneri, and Lactobacillus plantarum. Some atypical genera such as Weissella and Bacillus were also found in the residual must. Our results suggest that the lactic acid bacteria could strongly be implicated in the organoleptic attributes of this traditional Mexican distilled beverage.

The concentrations of metals, Cd, Cu, Fe, Mn, Ni, Pb, and Zn were determined in some lagoons to establish the level of metal pollution. The lagoons studied were Alvarado lagoon, Veracruz; San Andres lagoon, Tamaulipas; and Terminos lagoon, Campeche. The concentrations were determined in water, oyster (Crassostrea virginica), and sediments. Metals were accumulated in either oysters or sediments. Cu and Zn were higher in oysters and Fe and Mn were higher in sediments. The results in water samples were compared with the limit established by the Secretaria de Ecologia and Desarrollo Urbano Report and briefly discussed.

Dicho análisis se efectuará a partir de dos premisas fundamentales: una de ellas es la internacionalización del proceso productivo que se manifiesta con la presencia de una nueva división internacional del trabajo y lo que en este ensayo es llamada economía campesina, que fue la fuente primaria de la acumulación de capital de la agricultura mexicana, la cual jugará un papel importante para la acumulación de capital de la agricultura de los Estados Unidos de América, mediante la oferta de fuerza de trabajo agrícola barata, permitiendo el desarrollo de la agricultura comercial, modelo que ahora se ha volcado sobre la economía campesina condenándola a su desaparición como forma de subsistencia de la población rural, a quien expulsa de sus unidades de producción mediante el acaparamiento y el rentismo.

Full Text Available One of the advantages of land cover monitoring by means of satellite images is to have several observations of a specific place. That gives us the possibility of detecting land changes. This paper exemplifies the use of change detection techniques and illustrates how the combination of digital image information and ancillary data in a geographic information system can give us a much clear idea of the ecological importance of transformations. A semiarid zone, in the Tamaulipas and Nuevo León States was selected. This area, south of the US border, is part of the San Juan River basin. The change image was obtained from the vegetation index difference of 3 Landsat MSS images. This change image was combined with digital land use maps to produce the change distribution. This procedure flags a marked decrease in the extent of the water bodies, an increase in vegetation cover in areas of temporal agriculture and grassland, and the little variation of the forested areas. With the aid of the elevation model it was possible to discriminate the change in areas of high water erosion risk. The loss of the vegetation cover in areas of high slope is not frequent.

Full Text Available The text addresses two emblematic massacres of migrants from contemporary Mexico, the San Fernando, Tamaulipas massacre in 2010, and the Cadereyta, Nuevo Leon massacre in 2012 as examples of a "necropolitan governmentality" of migrations in Mesoamerica. It is hypothesized that these massacres are, in addition to disputes over territorial control, crimes that with their performativity seek to exemplify the punishment for those who dare to disobey the laws of access and permanence in the North American territory (Mexico or United States of America. It is an analytical exercise that emphasizes the violence against migrants, which are essential scenarios to be understood in contemporary migratory studies.

Full Text Available This research aims to determine information regarding the level of job satisfaction of the Mexican Institutes of Technology (TecNM. in northeastern México with a structural equation model. The methodology designed to explain job satisfaction level consisted of a survey questioner with 37 questions applied to a sample of 485 professors and administrators from the National Institutes of Technology located in Tamaulipas Mexico (Cd. Victoria, Matamoros, Nuevo Laredo, Nuevo León (Linares City and Coahuila (Saltillo. The sample was random, stratified, and structured with questions mostly using a Likert scale. Six fundamental hypotheses were formulated for testing a structural equation model with job satisfaction as dependent variable. A database of cross section data was created with the sample, and processed with a statistical data analysis software called SmartPLS V. 2.0 (M3. The results of the structural model show that two of the five constructs are highly relevant and statistically significant on their impact on job satisfaction and they refer to the benefits received by employees and the working environment we live in institutions. It is concluded generally that the perception we have in relation to variables that influence job satisfaction are not significant as we think.

Studies on caiman, Caiman crocodilus chiapasius, in Mexico are scarce. The present study was conducted to evaluate the key characteristics regarding the reproductive ecology of caiman in Mexico. We conducted nest searches from April to September 2014. We observed that nests were built in June and that hatching occurred in September and October. The phase of the moon had an effect on nesting events. The height of the nest, the distance to the nearest tree, and the distance from the top of the nest to the first egg were related to hatching success and incubation temperature. (Author)

The role of feral mammals on wildlife infectious disease prevalence in two nature reserves within Mexico City limits.

Science.gov (United States)

Suzán, Gerardo; Ceballos, Gerardo

2005-09-01

Wild and feral medium-sized mammals were live trapped at two natural protected areas within the Mexico City limits to determine antibody prevalence for the most common infectious diseases (rabies, toxoplasmosis, and canine parvovirus) in dogs and cats. Mammals were trapped during the dry (March-April) and rainy seasons (July-August) of 1996 and 1997. A total of 68 individuals were captured, representing 8 species: opossums (Didelphis virginiana), ringtails (Bassariscus astutus), spotted skunks (Spilogale gracilis), weasels (Mustela frenata), rock squirrels (Spermophilus variegatus), Mexican gray squirrels (Sciurus aureogaster), feral cats (Felis catus), and feral dogs (Canis familiaris). There was marked seroprevalence for parvovirus (86.6%) and lower seroprevalences for both toxoplasma (23.9%) and rabies (17.9%). There were no significant prevalence differences among mammals in both protected areas, which were of contrasting size and isolation (i.e., small and isolated versus large and nonisolated). We suggest that high seroprevalence of these three infectious agents in wild mammals is a result of the high densities of feral dogs and cats in the two areas sampled. Feral dogs are able to maintain the infectious agents in these localities regardless of the protected area size and isolation. However, the native mammals of the small and isolated reserve are more vulnerable to infectious diseases because of small population size and genetic bottlenecks. Our results indicate that natural areas in and around Mexico City are a refugium for latent infectious agents, several of which are zoonotic. These findings suggest that conservation measures, such as eradication of feral mammals and vaccination programs, in the protected areas and surrounding areas could be beneficial.

Estimation of gas reserves in North America

International Nuclear Information System (INIS)

Laherrere, J.

2001-01-01

If the oil market is global, the gas market is divided into three zones: North America, Europe and Asia. The official forecast of the future demand of North America gas is optimist as it is based on estimates of resources which are ten times those of the proved reserves. The poor practice (SEC rules) of proved reserves (when the rest of the world uses proven+probable) leads to a constant revision and a growth of the past discoveries, showing well a wrong evaluation. The official databases are then very poor, even those of the US federal domain, which have to be public. The study of the technical data of reserves of US, Canada and Mexico leads to a more pessimistic estimation of the ultimate reserves and then to the future local supply. In the Gulf of Mexico (the main hope), the production of natural gas in shallow water decline and the discoveries in the deep-water are mainly oil. The non-conventional gas seems to level. But the future demand is also too optimistic, based on cheap price and on a steady growth. However the local gas supply will be likely insufficient, and the demand will need imported liquefied natural gas. (author)

Evolution of Northeastern Mexico during the early Mesozoic: potential areas for research and exploration José Rafael Barboza-Gudiño

2013-05-01

The lower Mesozoic succession of central and northeastern Mexico was deposited in a late Paleozoic-early Mesozoic remnant basin, formed at the westernmost culmination of the Ouachita-Marathon geosuture, after closure of the Rheic Ocean. Triassic fluvial deposits of El Alamar Formation (El Alamar River) are distributed in Tamaulipas and Nuevo Leon as remnants of a continental succession deposited close to the western margin of equatorial Pangea, such fluvial systems flowed to the ocean, located to the west and contributed to construction of the so-called Potosí submarine fan (Zacatecas Formation). Petrographic, geochemical, and detrital zircon geochronology studies indicate that both, marine and continental Triassic successions, come from a continental block and partially from a recycled orogen, showing grenvillian (900-1300 Ma) and Pan-African (500-700 Ma) zircon age populations, typical for peri-gondwanan blocks, in addition to zircons from the Permo-Triassic East Mexico arc (240-280 Ma). The absence of detrital zircons from the southwestern North American craton, represent a strong argument against left lateral displacement of Mexico to the southwest during the Jurassic up to their actual position, as proposed by the Mojave-Sonora megashear hypothesis. Towards the end of the Triassic or in earliest Jurassic time, began the subduction along the western margin of Pangea, which causes deformation of the Late Triassic Zacatecas Formation and subsequent magmatism in the continental Jurassic arc known as "Nazas Arc ", whose remnants are now exposed in central- to northeastern Mexico. Wide distributed in northern Mexico occurred also deposition of a red bed succession, overlying or partially interstratified with the Early to Middle Jurassic volcanic rocks of the Nazas Formation. To the west and southwest, such redbeds change transitionally to marine and marginal sedimentary facies which record sedimentation at the ancient paleo-pacific margin of Mexico (La Boca and

This is the Phase One contract report to the United States Department of Energy, United State Geological Survey and the Jicarilla Apache Indian Tribe on the project entitled''Outcrop Analysis of the Cretaceous Mesaverde Group: Jicarilla Apache Reservation, New Mexico.'' Field work for this project was conducted during July and August 1998, at which time fourteen measured sections were described and correlated on or adjacent to Jicarilla Apache Reservation lands. A fifteen section, described east of the main field area, is included in this report, although its distant location precluded use in the correlation's and cross-sections presented herein. Ground-based photo mosaics were shot for much of the exposed Mesaverde outcrop belt and were used to assist in correlation. Outcrop gamma-ray surveys at six of the fifteen measured sections using a GAD-6 scintillometer was conducted. The raw gamma-ray data are included in this report, however, analysis of those data is part of the ongoing Phase Two of this project

Aquatic food webs in mangrove and seagrass habitats of Centla Wetland, a Biosphere Reserve in Southeastern Mexico

Directory of Open Access Journals (Sweden)

Manuel Mendoza-Carranza

Full Text Available Mangrove and seagrass habitats are important components of tropical coastal zones worldwide, and are conspicuous habitats of Centla Wetland Biosphere Reserve (CWBR in Tabasco, Mexico. In this study, we examine food webs in mangrove- and seagrass-dominated habitats of CWBR using stable isotope ratios of carbon and nitrogen. Our objective was to identify the importance of carbon derived from mangroves and seagrasses to secondary production of aquatic consumers in this poorly studied conservation area. Carbon and nitrogen isotope ratios of basal sources and aquatic consumers indicated that the species-rich food webs of both habitats are dependent on riparian production sources. The abundant Red mangrove Rhizophora mangle appears to be a primary source of carbon for the mangrove creek food web. Even though dense seagrass beds were ubiquitous, most consumers in the lagoon food web appeared to rely on carbon derived from riparian vegetation (e.g. Phragmites australis. The introduced Amazon sailfin catfish Pterygoplichthys pardalis had isotope signatures overlapping with native species (including high-value fisheries species, suggesting potential competition for resources. Future research should examine the role played by terrestrial insects in linking riparian and aquatic food webs, and impacts of the expanding P. pardalis population on ecosystem function and fisheries in CWBR. Our findings can be used as a baseline to reinforce the conservation and management of this important reserve in the face of diverse external and internal human impacts.

Building ties: social capital network analysis of a forest community in a biosphere reserve in Chiapas, Mexico

Full Text Available Governance of the commons depends on the capacity to generate collective action. Networks and rules that foster that collective action have been defined as social capital. However, their causal link is still not fully understood. We use social network analysis to assess social capital, decision-making, and collective action in a forest-based common pool resource management in La Sepultura Biosphere Reserve (Chiapas, Mexico. Our research analyzes the productive networks and the evolution of coffee groups in one community. The network shows some centrality, with richer landholders tending to occupy core positions and poorer landless peasants occupying peripheral ones. This has fostered the community's environmentally oriented development but has also caused internal conflicts. Market requirements have shaped different but complementary productive networks, where organic coffee commercialization is the main source of bridging ties, which has resulted in more connectivity and resilience. Conservation attitudes, along with the institutional setting of the community, have promoted collective action. The unresolved conflicts, however, still leave some concerns about governance in the future.

Full Text Available OBJETIVO: Generar un diagnóstico sobre la disponibilidad de algunos medicamentos esenciales del Cuadro Básico de Insumos (CBI en las unidades de primer nivel de atención de la Secretaría de Salud en el estado de Tamaulipas, México. MATERIAL Y MÉTODOS: Entre septiembre y octubre de 1998 se llevó a cabo una encuesta en todas las unidades de primer nivel de tres jurisdicciones sanitarias de Tamaulipas. La disponibilidad de medicamentos se estudió en todas las unidades de dichas jurisdicciones sanitarias. Como instrumento de medición se utilizó una guía de verificación con una lista de 56 medicamentos y 10 insumos diversos. Para cada medicamento e insumo se calculó el número absoluto y la proporción de unidades que al momento de la verificación no contaban con dicho recurso. En las unidades con disponibilidad de medicamentos se estimó la mediana de la distribución. Como medida de resumen se estimó la mediana del total de medicamentos esenciales disponibles en todas las unidades. Posteriormente, se realizó este mismo ejercicio diferenciado por tipo de unidad. Se hicieron comparaciones directas entre la ausencia de uno o más medicamentos en las unidades y la disponibilidad de los mismos en los almacenes. Todo el proceso de análisis se realizó con el paquete estadístico Stata versión 5.0. RESULTADOS: Ninguna de las unidades visitadas contaba con ejemplares de todos los medicamentos incluidos en la lista. La unidad que más se acercó al total tenía 84% de los medicamentos y la que más se alejó contó apenas con 32%. Los problemas de disponibilidad de antibióticos, antihipertensivos, hipoglucemiantes y medicamentos para el tratamiento de deficiencias de hierro fueron particularmente significativos. En contraste, la disponibilidad de sales de rehidratación oral y métodos anticonceptivos y biológicos fue aceptable. CONCLUSIONES: Las instituciones de salud deberán generar alternativas para mejorar el acceso a los

Because of a steady depletion of reserves and the failure to make new discoveries in recent years, production of crude oil in New Mexico declined in 1979 with a production of 74.7 million bbls (barrels), which was 3.4 million bbls or 4.6 percent less than 1978 production. Although condensate production increased slightly over the previous year, total crude and condensate production continued to decline. Natural-gas production increased in 1979 by 3,565,351 thousand cu ft or 4 percent from the previous year, with an increase in production occurring in northwest New Mexico. Drilling continued to increase as the total number of well completions in New Mexico in 1979 was the highest in the past 9 yrs. Primary and secondary crude oil reserves were calculated for 50 major pools in southeast New Mexico and for selected oil and gas wells in northwest New Mexico. Coal production increased 1.8 million tons in 1979 or 14 percent over 1978 production, and a more extensive expansion will depend partly on factors such as the availability of rail transportation to new areas. The development of synthetic fuel technology may have a substantial impact on longer term coal production. Production of U 3 O 8 declined 13 percent from 1978 with 7420 tons U 3 O 8 reported as production in 1979. A depressed uranium market and other economic factors contributed to the decline in production. New Mexico, however, continues to lead the nation in production and uranium reserves. Researchers are continuing to explore geothermal energy applications and to characterize geothermal systems in the state, and the US Bureau of Land Management has issued 126 geothermal leases that remain active. Recent geothermal exploration activity has been detailed for 14 companies

AIDS in Mexican prisons.

The human rights organization Americas Watch, which toured Mexican prisons, reported in 1991 that all prisoners with HIV infection in the Mexico City area were housed in a single AIDS ward in Santa Marta Prison. In 1991, the 16-bed facility had 15 patients; in 1993, this number had increased by 5. In Mexico City, with 3 prisons holding over 2000 male adults each, there were only 20 known infected prisoners in the AIDS ward at Santa Marta. In 1991, authorities at Matamoros, in the state of Tamaulipas, insisted that none of their inmates had ever been diagnosed as infected with HIV. The prison physician at Reynosa indicated that only 2 inmates since 1985 had ever been diagnosed as infected. In 1992, the prison in Saltillo, in the state of Coahuila, reported that here had yet to be a single positive test for HIV. The prison at Reynosa held 1500 people and only 2 inmates were diagnosed as having AIDS between 1985 and 1991. Prisons at Matamoros and Saltillo held similar numbers but had no experience of infected inmates. A survey of 2 prisons in the state of Tamaulipas indicates that around 12% of the population may use IV drugs, and 9% indicate sharing needles. It is possible for prisoners to die of diseases like pneumonia, associated with AIDS, without the connection to AIDS being diagnosed. Each state, and possibly each prison in Mexico, has its own particular AIDS policies. Santa Marta was the single facility in Mexico City used to house AIDS-infected prisoners, who were segregated. Finally, the prison at Saltillo required all women entering the facility to have a medical examination, including a test for HIV. High-level prison personnel have demonstrated ignorance and fear of AIDS and intolerance of infected prisoners. Mexico must reassess the need to provide adequate medical care to offenders who are sick and dying behind bars.

Role of forest conservation in lessening land degradation in a temperate region: the Monarch Butterfly Biosphere Reserve, Mexico.

2014-06-01

With international concern about the rates of deforestation worldwide, particular attention has been paid to Latin America. Forest conservation programmes in Mexico include Payment for Environmental Services (PES), a scheme that has been successfully introduced in the Monarch Butterfly Biosphere Reserve. To seek further evidence of the role of PES in lessening land degradation processes in a temperate region, the conservation state of the Cerro Prieto ejido within the Reserve was assessed by an analysis of changes in vegetation cover and land-use between 1971 and 2013. There were no changes in the total forest surface area, but the relative proportions of the different classes of cover density had changed. In 1971, closed and semi-closed forest occupied 247.81 ha and 5.38 ha, 82.33% and 1.79% of the total area of the ejido, respectively. By 2013, closed forest had decreased to 230.38 ha (76.54% of the ejido), and semi-closed cover was 17.23 ha (5.72% of the ejido), suggesting that some semi-closed forest had achieved closed status. The final balance between forest losses and recovery was: 29.63 ha were lost, whereas 13.72 ha were recovered. Losses were mainly linked to a sanitation harvest programme to control the bark beetle Scolytus mundus. Ecotourism associated with forest conservation in the Cerro Prieto ejido has been considered by inhabitants as a focal alternative for economic development. Consequently, it is essential to develop a well-planned and solidly structured approach based on social cohesion to foster a community-led sustainable development at local level.

Mexico: swapping crude for atoms

International Nuclear Information System (INIS)

Navarro, B.

1982-01-01

Mexico, considered the Saudi Arabia of the Western Hemisphere because of its proven and potential petroleum reserves, has surprised the world: it has embarked on the biggest nuclear-electric program in the Third World, only to postpone it days before scheduled approval of an international bidding (on which the atomic energy industry had pinned its hopes). A graph shows Mexican supplies of electricity by source with official projections to 1990. The point of entrance of the first nuclear reactor, originally scheduled for 1982, won't come onstream until 1983; and how nuclear-generated electricity grows close to 5% of the total in 1990. The big question is, will the future President of Mexico give the green light to the atomic megaproject. And if he does, how will Mexico deal with the serious logistics problems and grave ecological implications confronting the industry worldwide. In this issue, the author and Energy Detente touch on these questions and review the nuclear power status of Mexico, as well as addressing some of its global problems. Also presented in this issue is an update of the fuel price/tax series for the Western Hemisphere countries

Variable merozoite surface antigens of Babesia bovis are exposed glycoproteins having a role in erythrocyte invasion. Members of this gene family include msa-1 and msa-2 (msa-2c, msa-2a(1), msa-2a(2) and msa-2b). To determine the sequence variation among B. bovis Mexican isolates using msa-2b as a genetic marker, PCR amplicons corresponding to msa-2b were cloned and plasmids carrying the corresponding inserts were purified and sequenced. Comparative analysis of nucleotide and deduced amino acid sequences revealed distinct degrees of variability and identity among the coding gene sequences obtained from 16 geographically different Mexican B. bovis isolates and a reference strain. Clustal-W multiple alignments of the MSA-2b deduced amino acid sequences performed with the 17 B. bovis Mexican isolates, revealed the identification of three genotypes with a distinct set each of amino acid residues present at the variable region: Genotype I represented by the MO7 strain (in vitro culture-derived from the Mexico isolate) as well as RAD, Chiapas-1, Tabasco and Veracruz-3 isolates; Genotype II, represented by the Jalisco, Mexico and Veracruz-2 isolates; and Genotype III comprising the sequences from most of the isolates studied, Tamaulipas-1, Chiapas-2, Guerrero-1, Nayarit, Quintana Roo, Nuevo Leon, Tamaulipas-2, Yucatan and Guerrero-2. Moreover, these three genotypes could be discriminated against each other by using a PCR-RFLP approach. The results suggest that occurrence of indels within the variable region of msa-2b sequences can be useful markers for identifying a particular genotype present in field populations of B. bovis isolated from infected cattle in Mexico.

This paper presents a historical overview of the energy sector in Mexico, an important player in the world energy market, whose trade and market policies support economic development and foreign investment. Trade, commerce and investment between Canada and Mexico has been increasing steadily ever since the North American Free Trade Agreement (NAFTA) came into effect in January 1994. TransAlta Corporation and Westcoast Energy Inc. are two very active investors in the energy sector. Westcoast has invested in increasing natural gas and oil production from the Cantarell field in the Gulf of Mexico through the Campeche Natural Gas Compression Service Project and the Cantarell Nitrogen Plant. TransAlta has invested in two natural gas fired power plants which are both expected to be in service for the second quarter of 2003. These include the 252 MW Campeche facility and the 259 MW Chihuahua facility. Mexico has proven crude oil reserves of 27 billion barrels, proven natural gas reserves of 30 tcf, and in 2000 had a crude oil production of 3.4 mmbl/d, of which half was exported. The energy sector in Mexico may need about $120 billion of investment by 2010, of which half will be used for crude oil exploration and production, transportation and refining and the other half for natural gas exploration and production, transportation and distribution and power generation. Recently, the Mexican government embarked on two initiatives. The first to increase the productivity and profitability of PEMEX, the largest corporation in Mexico and one of the largest in the world, and to allow a form of private investment in the development of non-associated natural gas fields. This paper discussed the significance of the Multiple Service Contracts (MSC) program which involves domestic and international petroleum exploration and development. It also discussed forms of business organizations, taxation and structuring, financial issues, employment and the North American Free Trade Agreement

Abstract The study of biodiversity of Chrysomelidae in Mexico and its variation within ecological gradients has increased recently, although important areas in the country remain to be explored. We conducted a faunistic inventory and analyzed the elevational and temporal variation of leaf beetle communities in the Sierra de San Carlos, in the state of Tamaulipas, in northeastern Mexico. This is an area with high to extreme priority for conservation, and due to its insular geographical position and to the vegetational communities present, it must be considered as a sky island. We selected seven sample sites distributed in different elevations within three localities, and comprising different vegetational communities. At each site, we randomly delimited 12 sample plots of 400 m2 where sampling was conducted by entomological sweep netting and collecting directly by hand. Sampling was conducted monthly at each plot, for a total of 1,008 samples between February 2013 and January 2014. By the end of the study, we had obtained a total of 3,081 specimens belonging to six subfamilies, 65 genera, and 113 species, with Trichaltica scabricula (Crotch, 1873) being recorded for first time in Mexico. Species richness was less than the values observed at other studies conducted in the same region, which is attributed to differences in the number of plant species and to the insular location of Sierra de San Carlos; however, the higher diversity values suggest a higher quality of natural resources and vegetational communities. No consistent pattern of leaf beetle communities was correlated with elevation, although higher values of species richness and diversity were obtained at the highest elevation site. The seasonal gradient showed that the rainy season is most favorable for leaf beetle communities. We found that species composition was different between sites and months, and also that there exists a significant association between the abundance obtained at each site and

Segovia, N.; Tejera, A.; Bulbulian, S.; Palma, F.

1991-10-01

Mexico is traditionally a mining country and the first information about the presence of uranium is related to mine exploitation. Around 1945 when uranium became economically important, a rumor had spread that large amounts of black ceramics from Oaxaca were being purchased and sent abroad because of its assumed high uranium content. It was only in 1949 when minerals containing thorium and uranium were declared by law as 'National Reserves'. In those years a radium emanation plant was installed at the 'Hospital General' in Mexico City with the main purpose of carrying out radon seed implantation in tumors. In the fifties a radium dial painting facility was operating in the city of Toluca some 70 km from Mexico City. In 1955, when the National Commission of Nuclear Energy (CNEN) was founded by a government decree, two main activities were in sight: a training program on 'Radioisotope Techniques and Nuclear Instrumentation' and the creation of specialized laboratories. In this paper a general description of these events and undertakings spanning the decades 1940 to 1970 is given. (Author)

The present investigation project pretends toward analyze the possibility of pumping water using Aeolian energy from the Soto la Marina River to the Contadero Lagoon, through an eight kilometers channel. In order to obtain this objective it is necessary to analyze diverse configurations for Aeolian energy converters as well as to determine the Aeolian potential of the site. An isolated Aeolian energy pumping system will be analyzed, that is to say, without interconnection with the electric power network and another interconnected with this network. In addition, with the installation of meteorological monitoring stations a partial evaluation of the Aeolian resource in the zone will be made. This research project was born as a result of an invitation of the Dr. Eric Gustafson, President of Conservation Mexico A.C. and of Ing. Virgilio Garza, President of the Vigia Group, to participate in a project called Laguna Flamingo. Such project deals with the restoration of a habitat of aquatic birds in the Contadero Lagoon, property of Ing. Virgilio Garza in Soto la Marina, Tamaulipas, Mexico.

The paper focused on how the financial crisis and merger activity in Latin America will impact electricity reform in Mexico. It was noted that under Mexico`s Policy Proposal for Electricity Reform of the Mexican Electricity Industry, the financial community will seek to back companies in power generation, transportation and distribution. The difficulty of financing government businesses undergoing privatization was also discussed with particular emphasis on the challenge of accepting political and regulatory risks. The Latin private equity market and Canadian investment in Mexico was also reviewed. Since NAFTA (North American Free Trade Agreement) went into affect in 1994, Canadian investment in Mexico has more than tripled. Canadian companies have invested more than C$1.7 billion in Mexico since NAFTA. Pricewaterhouse Coopers Securities is a global investment bank which sees large opportunities in the Mexican energy market. They predict that in five years, Mexico will experience a gradual liberalization of the oil and gas sector, and a full liberalization of the gas pipeline and distribution business and the power generation, transmission and distribution business. 3 figs.

A series of overhead viewgraphs accompanied this presentation which focused on various aspects of the natural gas industry in Mexico. Some of the viewgraphs depicted statistics from 1998 regarding natural gas throughput from various companies in North America, natural gas reserves around the world, and natural gas reserves in Mexico. Other viewgraphs depicted associated and non-associated natural gas production from 1988 to 1998 in million cubic feet per day. The Burgos Basin and the Cantarell Basin gas production from 1997 to 2004 was also depicted. Other viewgraphs were entitled: (1) gas processing infrastructure for 1999, (2) cryogenic plant at Cd. PEMEX, (3) average annual growth of dry natural gas production for 1997-2004 is estimated at 5.2 per cent, (4) gas flows for December 1998, (5) PGPB- interconnect points, (6) U.S. Mexico gas trade for 1994-1998, (7) PGPB's interconnect projects with U.S., and (8) natural gas storage areas. Technological innovations in the industry include more efficient gas turbines which allow for cogeneration, heat recovery steam generators which reduce pollutant emissions by 21 per cent, cold boxes which increase heat transfer efficiency, and lateral reboilers which reduce energy consumption and total costs. A pie chart depicting natural gas demand by sector shows that natural gas for power generation will increase from 16 per cent in 1997 to 31 per cent in 2004. The opportunities for cogeneration projects were also reviewed. The Comision Federal de Electricidad and independent power producers represent the largest opportunity. The 1997-2001 investment program proposes an 85 per cent sulphur dioxide emission reduction compared to 1997 levels. This presentation also noted that during the 1998-2001 period, total ethane production will grow by 58 tbd. 31 figs

Mexico: Imports or exports?

Estrada, J.

2002-01-01

This presentation provides an overview of Mexico's energy sector. Proven oil reserves place Mexico in ninth position in the world and fourth largest in natural gas reserves. Energy is one of the most important economic activities of the country, representing 3 per cent of Gross Domestic Product (GDP). Oil exports represent 8.4 per cent of total exports. Approximately 40 per cent of total public investment is earmarked for energy projects. The author discusses energy resources and energy sector limitations. The energy sector plan for the period 2001-2006 is discussed. Its goals are to ensure energy supply, to develop the energy sector, to stimulate participation of Mexican enterprises, to promote renewable energy sources, and to strengthen international energy cooperation. The regulatory framework is being adapted to increase private investment. Some graphs are presented, displaying the primary energy production and primary energy consumption. Energy sector reforms are reviewed, as are electricity and natural gas reforms. The energy sector demand for 2000-2010 and investment requirements are reviewed, as well as fuel consumption for power generation. The author discusses the National Pipeline System (SNG) and the bottlenecks caused by pressure efficiency in the northeast, flow restriction on several pipeline segments, variability of the Petroleos Mexicanos (PEMEX) own use, and pressure drop on central regions. The entire prospect for natural gas in the country is reviewed, along with the Strategic Gas Program (PEG) consisting of 20 projects, including 4 non-associated natural gas, 9 exploration and 7 optimization. A section dealing with multiple service contracts is included in the presentation. The authors conclude by stating that the priority is a national energy policy to address Mexico's energy security requirements, to increase natural gas production while promoting the diversification of imports, and a regulatory framework to be updated in light of current

Although production of U 3 O 8 declined only slightly in 1980, New Mexico's share of domestic production has declined from 48% in 1976 to 35% in 1980. Production projections indicate a continued decline in 1981 and lower production until at least 1984. New Mexico has 41% of total domestic reserves producible in the $50-per-lb cost category. In keeping with the anticipated steady depletion of reserves, production of crude oil in New Mexico was 69.9 million bls, a 6.3% decline in production from 1979. Condensate production of 5.4 million bbls in 1980, however, represented an increase of 7% from 1979 production. Although natural gas production was the lowest since 1970 and declined by 2.6% from 1979 production, 1980 was the 15th year that production exceeded 1 trillion cu ft. Despite declines in production, the valuation of oil and gas production has increased significantly with oil sales doubling from the previous year and gas sales increasing by $409 million because of higher prices. Reserves have been estimated to be 959 million bbls of crude oil and 17.667 trillion cu ft of natural gas. Production of 19.5 million short tons of coal in 1980 represented a 33% increase over 1979 production and an increase of 157% since 1970. Coal resources in New Mexico are estimated to be 180.79 billion short tons, and production is projected to incease to 39.61 million tons in 1985 and 67.53 million tons in 1990. The most notable developments in geothermal energy have been in technical advances in drilling, testing, and applications, especially in the area of hot dry rock systems. The US Bureau of Land Management has issued 113 geothermal leases that remain active. Recent geothermal exploration activity has been detailed for 21 companies

This presentation highlights the results of a recently completed study that examines the Texas- Mexico multimodal transport system already in place, current plans for improvements or expansion, and opportunities and constraints faced by each transport mode -- motor carriage, rail, maritime, and air. Particular emphasis is given to findings regarding transportation developments in Mexico. The study concludes that in Mexico, all modes are working at establishing new services and strategic alliances, intermodal arrangements are on the rise, and private-sector participation in infrastructure improvements is growing daily at Mexican seaports and airports as well as within that nation's highway and rail systems. This presentation looks at developments that concern privatization, deregulation, infrastructure improvements, financing arrangements, and new services in Mexico.

Mexico's energy dilemmas in an interdependent world

International Nuclear Information System (INIS)

Bauer, M.

2008-01-01

Mexico's energy system is overwhelmingly dependent on hydrocarbons. Although a significant producer of oil and gas, and a considerable exporter of crude oil, it is increasingly dependent on imports of oil products and natural gas for its internal energy demand. In a World where free trade is increasing the interdependence of the industrialized economies, Mexico's energy policy dilemma is basically between maintaining as much as possible its self sufficiency; or relying on imports, while generating oil revenues through exports to invest in developing a diversified economy. Energy demand projections to 2030 are carried out that exhibit the limitations of present available oil and gas proved reserves under past policies. Alternative energy policy scenarios are then examined. (authors)

Selling the SPR [Strategic Petroleum Reserve

International Nuclear Information System (INIS)

Gurney, J.

1997-01-01

The Strategic Petroleum Reserve (SPR) in the USA was created in 1975, in conjunction with the wider reserve programme of the International Energy Agency, following the 1973/74 Arab oil embargo. The only source of funding for the SPR has been annual appropriations bills from Congress. In 1994, however, Congress, seeking ways to balance the nation's budget and given the perception by many free market economists that the danger of serious oils supply disruption has passed, refused to allocate funds for SPR oil purchases. No crude oil stocks have been added to the reserve since then. In 1996, congress took the further step of requiring sales of oil from the reserve in order to pay for the programme's running costs and to meet the costs of maintaining the reserve's storage facilities. The reserve oil is stored in caverns under salt domes in the coastal regions of the Gulf of Mexico and some of these are beginning to fracture to the extent that they are having to be decommissioned. The SPR has been investigating ways of raising money in order to lessen its dependence on Congress. These include leasing pipelines and a marine terminal, and allowing the storage of foreign owned oil in underused caverns. (author)

Family structure and child anemia in Mexico.

Science.gov (United States)

Schmeer, Kammi K

2013-10-01

Utilizing longitudinal data from the nationally-representative Mexico Family Life Survey, this study assesses the association between family structure and iron-deficient anemia among children ages 3-12 in Mexico. The longitudinal models (n = 4649), which control for baseline anemia status and allow for consideration of family structure transitions, suggest that children living in stable-cohabiting and single-mother families and those who have recently experienced a parental union dissolution have higher odds of anemia than those in stable-married, father-present family structures. Interaction effects indicate that unmarried family contexts have stronger associations with anemia in older children (over age five); and, that the negative effects of parental union dissolution are exacerbated in poorer households. Resident maternal grandparents have a significant beneficial effect on child anemia independent of parental family structure. These results highlight the importance of family structure for child micronutrient deficiencies and suggest that understanding social processes within households may be critical to preventing child anemia in Mexico.

Population, petroleum, and politics: Mexico at the crossroads. Part 2. The potentials and problems of Mexican oil resources.

Science.gov (United States)

Gallagher, C F

1980-01-01

The 2 most important factors which will influence Mexico's future economic development are the country's overpopulation problem and the manner in which the country's oil reserves are exploited. This document describes the historical development of Mexico's oil industry and the current struggle of the government to ensure that the oil resources contribute toward the sound economic development of the country. The government expropriated foreign oil companies in 1938 and today most of the oil operations in Mexico are conducted by the state controlled Pemex Company. In recent years extensive oil reserves were discovered in Mexico and the country is now in the position of having large oil reserves at a time when oil prices are increasing. Known crude oil reserves are estimated at 31 billion barrels; however, an unconfirmed report by Pemex in 1980 placed the known reserves at 50 billion barrels. In the past the management of Pemex was corrupt and inefficient and many top positions in the company were filled by retired politicians. The recent appointment of Jose Andres de Oteyza as Chairman of the Board and of Jorge Diaz Serrano as the Director-General should greatly improve Pemex operations. In developing the country's oil industry the government wants 1) to keep production low enough to offset inflation and to preserve the resource but 2) to produce enough oil so that the country has sufficient funds for investment and for operating needed social programs. The government may not be able to keep oil production down to acceptable levels. It may be forced to increase oil exports to compensate for its growing reliance on imported food and other imported products. In recent years Mexico's industrial productivity and its agricultural production declined. The government wants to avoid being placed in the position where it will be forced to trade large quantities of oil for needed food. The current government is promoting investment in agriculture and industrial development in

The nesting requirements of the Yellow-headed Parrot (Amazona oratrix) are poorly understood, despite their broad historical distribution, high demand for pet trade and current endangered status. Information concerning their nesting requirements is required in order to design specific restoration and conser- vation actions. To assess this, we studied their nesting ecology in the Central Pacific, Michoacan, Mexico during a ten year period. The analyzed variables ranged from local scale nest site characteristics such as nesting tree species, dimensions, geographic positions, diet and nesting forest patches structure, to large scale features such as vegetation use and climatic variables associated to the nesting tree distributions by an ecological niche model using Maxent. We also evaluated the parrot tolerance to land management regimes, and compared the Pacific nest trees with 18 nest trees recorded in an intensively managed private ranch in Tamaulipas, Gulf of Mexico. Parrots nested in tall trees with canopy level cavities in 92 nest-trees recorded from 11 tree species. The 72.8% of nesting occurred in trees of Astronium graveolens, and Enterolobium cyclocarpum which qualified as key- stone trees. The forests where the parrots nested, presented a maximum of 54 tree species, 50% of which were identified as food source; besides, these areas also had a high abundance of trees used as food supply. The lowest number of tree species and trees to forage occurred in an active cattle ranch, whereas the highest species rich- ness was observed in areas with natural recovery. The nesting cavity entrance height from above ground of the Pacific nesting trees resulted higher than those found in the Gulf of Mexico. We hypothesize that the differences may be attributed to Parrot behavioral differences adapting to differential poaching pressure and cavity avail- ability. Nesting trees were found in six vegetation types; however the parrots preferred conserved and riparian semi

Peasant coffee in the Los Tuxtlas Biosphere Reserve, Mexico: A critical evaluation of sustainable intensification and market integration potential

Anne Cristina de la Vega-Leinert

2016-12-01

Full Text Available Abstract Production of low-input, shaded coffee in the Los Tuxtlas UNESCO Biosphere Reserve (LTBR, Veracruz, Mexico, an economically marginalized but ecologically rich region, was strongly affected by the collapse in international prices and the reconfiguration of the Mexican coffee sector in the 1990s. This place-based study used qualitative methods to investigate local strategies to reactivate coffee cultivation and improve market integration. Ninety-five producers, processors and cooperative representatives were interviewed to: 1 characterize the different actors in the local coffee commodity chain; 2 explore how producers, organized or not, shape and are constrained by the local coffee sector, and 3 evaluate whether producers land use strategies may be compatible with conservation in the LTBR. We combine the Land Sparing and Sharing framework with the UNESCO Biosphere Reserve zonation system to conceptualize how coffee plantations can be spatially integrated in protected areas and facilitate synergies between local livelihoods and conservation. Our empirical study illustrates the complexity and dynamism of the LTBR coffee sector. It highlights the resourcefulness of producers in adapting their cultivation systems, but also the narrow maneuvering room farmers have to exploit textbook synergies between conservation and fair trade and / or certified organic markets. In principle, coffee cultivation can be expanded and intensified without affecting remaining primary forest (Land Sparing and contribute to maintain a diverse landscape matrix in productive agroforestry systems (Land Sharing. However, few producers have the means required to successfully achieve profitable and long-term market integration. Future research on sustainable land use management in, and around, protected areas needs to explicitly address local, sectoral and market dynamics as drivers of land use at the local level. Although these dynamics may create windows of opportunity

Full Text Available El ecosistema de Laguna de Términos es el más grande sistema fluvio lagunar estuarino del país y una de las reservas más importantes de flora y fauna costera en México. Desde la década de los setentas, parte de la infraestructura necesaria para la explotación del petróleo en el país se encuentra localizada en esta área. Su importante biodiversidad ha motivado diferentes estudios en el área que incluyen procesos de deforestación y ordenamiento del territorio. Se realizó un análisis de imágenes de satélite para determinar los cambios de uso del suelo y vegetación en el área entre 1974 y 2001. Los resultados indican que la selva tropical y el mangle presentan las mayores pérdidas de cobertura. En contraste, las áreas urbanas y los pastos inducidos han incrementado considerablemente su extensión. En el año 2001 más de la mitad del área ocupada por el ecosistema mostró cambios en sus coberturas originales y una tercera parte estaba deteriorada. La deforestación fue causada principalmente por el incremento de los pastizales y el crecimiento de las áreas urbanas. Sin embargo, estas pérdidas fueron atenuadas por la regeneración natural. Se concluye que la introducción de pasto para la ganadería y el desarrollo urbano fueron las principales causas de los cambios de uso de suelo, sin embargo, la industria petrolera asentada en el ecosistema ha fomentado indirectamente el crecimiento urbano y el auge ganadero.Terminos Lagoon ecosystem is the largest fluvial-lagoon estuarine system in the country and one of the most important reserves of coastal flora and fauna in Mexico.

Revenues from oil exports are an important part of government budgets in Mexico. A time-series analysis is conducted using monthly data from 1990 to 2005 examining three different specifications to determine how international oil price fluctuations and government income generated from oil exports influence fiscal policy in Mexico. The behavior of government spending and taxation is consistent with the spend-tax hypothesis. The results show that there is an inverse relationship between oil-related revenues and tax revenue from non-oil sources. Fiscal policy reform is urgently needed in order to improve tax collection as oil reserves in Mexico become more and more depleted. (author)

Over 1300 uranium and thorium occurrences are found in over 100 formational units in all but two counties, in all 1- by 2-degree topographic quadrangles, and in all four geographic provinces in New Mexico. Uranium production in New Mexico has surpassed yearly production from all other states since 1956. Over 200 mines in 18 counties in New Mexico have produced 163,010 tons (147,880 metric tons) of U 3 O 8 from 1948 to 1982, 40% of the total uranium production in the United States. More than 99% of this production has come from sedimentary rocks in the San Juan Basin area in northwestern New Mexico; 96% has come from the Morrison Formation alone. All of the uranium reserves and the majority of the potential uranium resources in New Mexico are in the Grants uranium district. About 112,500 tons (102,058 metric tons) of $30 per pound of U 3 O 8 reserves are in the San Juan Basin, about 55% of the total $30 reserves in the United States. Thorium reserves and resources in New Mexico have not been adequately evaluated and are unknown. Over 1300 uranium and thorium occurrences are described in this report, about 400 of these have been examined in the field by the author. The occurrence descriptions include information on location, commodities, production, development, geology, and classification. Over 1000 citations are included in the bibliography and referenced in the occurrence descriptions. Production statistics for uranium mines that operated from 1948 to 1970 are also included. Mines that operated after 1970 are classified into production categories. 43 figures, 9 tables

US service firms eye increased sales to Mexico

This paper reports on American service supply companies which hope the pending U.S.-Mexico free trade agreement will step up their sales of goods and service to Petroleos Mexicanos. They testified at a House foreign affairs subcommittee hearing on the oil aspects of the FTA and commented on a recent General Accounting Office report. Rep. Sam Gejdenson, (D-Conn.), subcommittee chairman, has been critical of FTA negotiations because it appears they will not open the Mexican oil sector to U.S. firms. Mexico's constitution bans foreign firms from owning Mexican reserves. It has been stated that the U.S. oil industry needs the business. The industry, particularly drillers, contractors, and manufacturers of oil equipment, has been hurting for more than 10 years now. They have lost more than 356,000 jobs in this sector in the last decade more than have been lost in the entire U.S. auto industry. Access to trade and investment in Mexico's oil sector could mean the difference between profit and bankruptcy for tens of thousands of small and medium size oil service contractors

2001-01-01

The purpose of phase 1 and phase 2 of the Department of Energy funded project Analysis of oil- bearing Cretaceous Sandstone Hydrocarbon Reservoirs, exclusive of the Dakota Sandstone, on the Jicarilla Apache Indian Reservation, New Mexico was to define the facies of the oil producing units within the Mancos Shale and interpret the depositional environments of these facies within a sequence stratigraphic context. The focus of this report will center on (1) redefinition of the area and vertical extent of the ''Gallup sandstone'' or El Vado Sandstone Member of the Mancos Shale, (2) determination of the facies distribution within the ''Gallup sandstone'' and other oil-producing sandstones within the lower Mancos, placing these facies within the overall depositional history of the San Juan Basin, (3) application of the principals of sequence stratigraphy to the depositional units that comprise the Mancos Shale, and (4) evaluation of the structural features on the Reservation as they may control sites of oil accumulation

Recent studies in Mexico have documented a significant increase in crack cocaine use, indicating the potential for an emerging drug epidemic. Ethnographic observations and interviews were used describe the profiles and patterns of use among street-recruited crack users in Mexico City. The data came from an international research collaboration funded by the National Institutes of Health. A polythetic typology was developed based on five dimensions central to categorizing patterns of crack use behavior: frequency of use, duration of use, context, social networks, and social contracts. Four types of users were discovered applying these dimensions: dabblers, stable users, crack heads, and old heads. Although several similarities were documented between patterns of crack use in Mexico and those in the United States and Western Europe, several key aspects distinguished crack users in this population: (1) self-regulated use; (2) non-linear progression of crack; and (3) the influence of the dimensions pertaining to setting, social networks, and social contract as contributing to understanding of the previous two. Further, we provide a discussion of how specific contextual factors in Mexico may be giving rise to these emerging patterns. Compared to the U.S. and Europe, this study finds that the majority of crack users were able to self-regulate their use without major disruption to daily social functioning. As crack use spreads in Mexico and other Latin American countries, we need to recognize the importance of social context in developing more tailored health and social responses that are specific to these developing countries.

Deep-water northern Gulf of Mexico hydrocarbon plays

Peterson, R.H.; Cooke, D.W.

1995-01-01

The geologic setting in the deep-water (depths greater than 1,500 feet) Gulf of Mexico is very favorable for the existence of large, commercial hydrocarbon accumulations. These areas have active salt tectonics that create abundant traps, underlying mature Mesozoic source rocks that can be observed expelling oil and gas to the ocean surface, and good quality reservoirs provided by turbidite sand deposits. Despite the limited amount of drilling in the deep-water Gulf of Mexico, 11 deep-water accumulations have been discovered which, when developed, will rank in the top 100 largest fields in the Gulf of Mexico. Proved field discoveries (those with announced development plans) have added over 1 billion barrels of oil equivalent to Gulf of Mexico reserves, and unproved field discoveries may add to additional billion barrels of oil equivalent. The Minerals Management Service, United States Department of the Interior, has completed a gulf-wide review of over 1,086 oil and gas fields and placed every pay sand in each field into a hydrocarbon play (plays are defined by chronostratigraphy, lithostratigraph, structure, and production). Seven productive hydrocarbon plays were identified in the deep-water northern Gulf of Mexico. Regional maps illustrate the productive limits of each play. In addition, field data, dry holes, and wells with sub-economic pay were added to define the facies and structural limits for each play. Areas for exploration potential are identified for each hydrocarbon play. A type field for each play is chosen to demonstrate the play's characteristics

Pretreatment drug resistance (PDR) levels to NNRTI approaching 10% have recently been reported in Mexico. However, subnational differences may exist in PDR prevalence and transmission dynamics. We longitudinally assessed HIV PDR in three geographic areas of Mexico. HIV-infected, antiretroviral-naive individuals were recruited from 2008 to 2016, from the Central Metropolitan Zone (CMZ), Cancun and Tijuana (1194, 773 and 668 respectively). PDR was estimated using the Stanford HIVdb tool from plasma HIV pol sequences. A higher proportion of females, lower education and lower employment rate were observed in Tijuana, while a higher proportion of MSM was observed in the CMZ (P Mexico. Even when increasing trends in efavirenz resistance were observed in the three areas, our observations support that, in a large country such as Mexico, subnational surveillance and locally tailored interventions to address drug resistance may be a reasonable option. © The Author 2017.

Natural gas expectations in Mexico a United States analyst's perspective

Energy Technology Data Exchange (ETDEWEB)

Foss, Michelle Michot [Energy Institute, University of Houston, TX (United States)

1996-07-01

The United States has a mature nature gas infrastructure but still needs continued improvements and expansion. Natural gas policy in the United States at both the federal and state level has generally not provide the right incentives or signals to producers, transports, distributors or customers and, as a result, natural gas not enjoy the market share that it probably should have. In 1973, natural gas consumption in the United States was 30 percent of total energy consumption. In 1994, the share for natural gas was 25 percent. Looking at the United States experience, natural gas has potential in Mexico, but there are constraints. It is useful to keep in mind the size of Mexico's market relative to her resource base of about 70 tcf of proven reserves and the potential and probable reserves that are likely to exist. Therefore, rational decision-makers will also need to consider whether Mexico could do well by exporting natural gas to the United States. [Spanish] Los Estados Unidos tienen una infraestructura madura en gas natural, pero aun necesita mejoras continuas y expansion. La politica de gas natural en los Estados Unidos, tanto en el ambito federal como en el ambito estatal, generalmente no ha proporcionado los incentivos o senales adecuados a los productores, transportadores, distribuidores o clientes y, como resultado, el gas natural no disfruta de la participacion en el mercado que probablemente deberia tener. En 1973, el consumo de gas natural era del 30 % del total del consumo de energia. En 1994, la participacion del gas natural fue del 25%. Viendo la experiencia de los Estados Unidos, el gas natural tiene potencial en Mexico. Pero existen factores limitantes. Es conveniente tener presente el tamano del mercado de Mexico en relacion con su recurso basico de sus reservas probadas de alrededor de 70 tcf y el potencial y probables reservas que pudieran existir. Por lo tanto, los responsables de las decisiones racionales tendran tambien la necesidad de

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.

Opportunity for America: Mexico`s coal future

Energy Technology Data Exchange (ETDEWEB)

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.

The use of medicinal plants in Mexico has been documented since pre-Hispanic times. Nevertheless, the level of use of medicinal plants by health professionals in Mexico remains to be explored. To evaluate the use, acceptance and prescription of medicinal plants by health professionals in 9 of the states of Mexico. Direct and indirect interviews, regarding the use and acceptance of medicinal plants, with health professionals (n=1614), including nurses, physicians, pharmacists, and odontologists from nine states in Mexico were performed from January 2015 to July 2016. The interviews were analyzed with the factor the informant consensus (FIC). The information obtained indicated that 46% of those interviewed feel patients should not use medicinal plants as an alternative therapy. Moreover, 54% of health professionals, and 49% of the physicians have used medicinal plants as an alternative therapy for several diseases. Twenty eight percent of health professionals, and 26% of the physicians, have recommended or prescribed medicinal plants to their patients, whereas 73% of health professionals were in agreement with receiving academic information regarding the use and prescription of medicinal plants. A total of 77 plant species used for medicinal purposes, belonging to 40 botanical families were reported by the interviewed. The results of the FIC showed that the categories of diseases of the digestive system (FIC=0.901) and diseases of the respiratory system (FIC=0.898) had the greatest agreement. This study shows that medicinal plants are used for primary health care in Mexico by health professionals. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

This paper reports that while Mexico's petrochemical industry has grown rapidly, it now faces shortages both in investment funds and in supplies of basic petrochemicals due to a financial crisis in the 1980s. Mexico has undertaken a series of policy reforms aimed at encouraging foreign and private investment, but these efforts have generally failed to entice U.S. investment in Mexico. U.S. petrochemical companies have cited unfavorable market conditions, insufficient basic petrochemical capacity in Mexico, concern about the reversibility of Mexican reforms, inadequate Mexican protection of intellectual property rights, and lack of investment protection for U.S. businesses as impediments to investment in Mexico. Cooperation between the two nations in overcoming these obstacles could help U.S. petrochemical companies maintain their positions in a competitive global market, while at the same time provide Mexico with much needed capital investment and technological expertise

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.

To identify the relationship between landscape use and dengue virus (DENV) occurrence in bats, we investigated the presence of DENV from anthropogenically changed and unaltered landscapes in two Biosphere Reserves: Calakmul (Campeche) and Montes Azules (Chiapas) in southern Mexico. Spleen samples of 146 bats, belonging to 16 species, were tested for four DENV serotypes with standard reverse transcriptase polymerase chain reaction (RT-PCR) protocols. Six bats (4.1%) tested positive for DENV-2: four bats in Calakmul (two Glossophaga soricina, one Artibeus jamaicensis, and one A. lituratus) and two bats in Montes Azules (both A. lituratus). No effect of anthropogenic disturbance on the occurrence of DENV was detected; however, all three RT-PCR–positive bat species are considered abundant species in the Neotropics and well-adapted to disturbed habitats. To our knowledge, this study is the first study conducted in southeastern Mexico to identify DENV-2 in bats by a widely accepted RT-PCR protocol. The role that bats play on DENV's ecology remains undetermined. PMID:24752688

Type 2 diabetes is the main health problem in Mexico. The large and growing number of cases and the remarkable economic impact of the disease support this statement. The condition is expressed at an earlier age and at a lower body mass index in Mexican mestizos compared with the age and body mass index reported in Caucasians. In addition, Mexican mestizos have an increased susceptibility to developing diabetic nephropathy. The Mexican health system needs major adjustments in order to prevent and treat type 2 diabetes. Treatment is not currently based on the needs and expectations of the patient. As a result, it is insufficient, belated, and costly. Close to 20% of the preventable deaths in Mexico are caused by diabetes and related metabolic diseases. Even a small decrease in this rate could result in substantial savings for the Mexican healthcare system. © The Author(s) 2016.

Multilayer geospatial analysis of water availability for shale resources development in Mexico

Science.gov (United States)

Galdeano, C.; Cook, M. A.; Webber, M. E.

2017-08-01

Mexico’s government enacted an energy reform in 2013 that aims to foster competitiveness and private investment throughout the energy sector value chain. As part of this reform, it is expected that extraction of oil and gas via hydraulic fracturing will increase in five shale basins (e.g. Burgos, Sabinas, Tampico, Tuxpan, and Veracruz). Because hydraulic fracturing is a water-intensive activity, it is relevant to assess the potential water availability for this activity in Mexico. This research aims to quantify the water availability for hydraulic fracturing in Mexico and identify its spatial distribution along the five shale basins. The methodology consisted of a multilayer geospatial analysis that overlays the water availability in the watersheds and aquifers with the different types of shale resources areas (e.g. oil and associated gas, wet gas and condensate, and dry gas) in the five shale basins. The aquifers and watersheds in Mexico are classified in four zones depending on average annual water availability. Three scenarios were examined based on different impact level on watersheds and aquifers from hydraulic fracturing. For the most conservative scenario analyzed, the results showed that the water available could be used to extract between 8.15 and 70.42 Quadrillion British thermal units (Quads) of energy in the typical 20-30 year lifetime of the hydraulic fracturing wells that could be supplied with the annual water availability overlaying the shale areas, with an average across estimates of around 18.05 Quads. However, geographic variation in water availability could represent a challenge for extracting the shale reserves. Most of the water available is located closer to the Gulf of Mexico, but the areas with the larger recoverable shale reserves coincide with less water availability in Northern Mexico. New water management techniques (such as recycling and re-use), more efficient fracturing methods, shifts in usage patterns, or other water sources need

The New Mexico Bureau of Mines and Mineral Resources (NMBMMR) in cooperation with the Radiation Licensing and Registration Section of the New Mexico Environment Department (NMED) and the US Environmental Protection Agency (EPA) have been evaluating geologic and soil conditions that may contribute to elevated levels of indoor radon throughout New Mexico. Various data have been integrated and interpreted in order to determine areas of high radon availability. The purpose of this paper is to summarize some of these data for New Mexico and to discuss geologic controls on the distribution of radon. Areas in New Mexico have been identified from these data as having a high radon availability. It is not the intent of this report to alarm the public, but to provide data on the distribution of radon throughout New Mexico

Mexico's nuclear paradox

Opposition to Mexico's nuclear reactors at Laguna Verde has grown during the last two years. The nuclear programme is blamed for being expensive and wasteful, and the decision to rely on the USA contradicts Mexico's espoused policy of greater independence from the USA. The way in which petroleum revenues were used to precipitate the nuclear option is compared with the lack of urgency given to renewable energy and greater energy efficiency. From a social and environmental perspective, as well as an economic one, Mexico's nuclear programme is judged expensive and irrelevant. (author)

Evidence That Marine Reserves Enhance Resilience to Climatic Impacts

Establishment of marine protected areas, including fully protected marine reserves, is one of the few management tools available for local communities to combat the deleterious effect of large scale environmental impacts, including global climate change, on ocean ecosystems. Despite the common hope that reserves play this role, empirical evidence of the effectiveness of local protection against global problems is lacking. Here we show that marine reserves increase the resilience of marine populations to a mass mortality event possibly caused by climate-driven hypoxia. Despite high and widespread adult mortality of benthic invertebrates in Baja California, Mexico, that affected populations both within and outside marine reserves, juvenile replenishment of the species that supports local economies, the pink abalone Haliotis corrugata, remained stable within reserves because of large body size and high egg production of the protected adults. Thus, local protection provided resilience through greater resistance and faster recovery of protected populations. Moreover, this benefit extended to adjacent unprotected areas through larval spillover across the edges of the reserves. While climate change mitigation is being debated, coastal communities have few tools to slow down negative impacts of global environmental shifts. These results show that marine protected areas can provide such protection. PMID:22855690

Mexico Wind Resource Assessment Project

Energy Technology Data Exchange (ETDEWEB)

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.

To analyze the relationship between nutritional status measured by anthropometry and the mental, psychomotor and language development of infants in marginalized rural areas of Mexico. Cross-sectional study with 576 infants aged from 7 to 26 months in four rural locations. Variables consisted of measures of anthropometric and cognitive development. Infants with short stature had a lower rate of language development, while birth weight was marginally associated with psychomotor development. Although acute malnutrition (identified by underweight) is no longer a problem in rural areas of Mexico, chronic malnutrition (expressed as stunting) is still common and is associated with alterations in mental development in the child population.

Boron and Coumaphos Residues in Hive Materials Following Treatments for the Control of Aethina tumida Murray.

Directory of Open Access Journals (Sweden)

Cesar Valdovinos-Flores

Full Text Available In the search of alternatives for controlling Aethina tumida Murray, we recently proposed the BAA trap which uses boric acid and an attractant which mimics the process of fermentation caused by Kodamaea ohmeri in the hive. This yeast is excreted in the feces of A. tumida causing the fermentation of pollen and honey of infested hives and releasing compounds that function as aggregation pheromones to A. tumida. Since the boron is the toxic element in boric acid, the aim of this article is to assess the amount of boron residues in honey and beeswax from hives treated with the BAA trap. For this aim, the amount of bioaccumulated boron in products of untreated hives was first determined and then compared with the amount of boron of products from hives treated with the BAA trap in two distinct climatic and soil conditions. The study was conducted in the cities of Padilla, Tamaulipas, and Valladolid, Yucatan (Mexico from August 2014 to March 2015. The quantity of boron in honey was significantly less in Yucatan than in Tamaulipas; this agrees with the boron deficiency among Luvisol and Leptosol soils found in Yucatan compared to the Vertisol soil found in Tamaulipas. In fact, the honey from Yucatan has lower boron levels than those reported in the literature. The BAA treatment was applied for four months, results show that the BAA trap does not have any residual effect in either honey or wax; i.e., there is no significant difference in boron content before and after treatment. On the other hand, the organophosphate pesticide coumaphos was found in 100% of wax samples and in 64% of honey samples collected from Yucatan. The concentration of coumaphos in honey ranges from 0.005 to 0.040 mg/kg, which are below Maximum Residue Limit (MRL allowed in the European Union (0.1 mg/kg but 7.14% of samples exceeded the MRL allowed in Canada (0.02 mg/kg.

The interrelations between climatic and soil conditions present in the agroecosystems of the dry zone of northern Mexico, have significant impact on the development of crops that results in impact on agricultural productivity. Soil degradation by excessive use of mechanical practices, has caused severe physical and chemical changes such as deterioration of the natural structure, loss of fertility, increased soil compaction and bulk density, and serious problems of erosion by wind and water. In order to know the influence of three organic fertilizers and soil preparation practices in the production of sorghum in San Fernando, Tamaulipas, was conducted this study. The experimental area present Vertisol soil type, and covers an area of 6 ha, which was subdivided into plots of one hectare. (Author) 6 refs.

Rapid effects of marine reserves via larval dispersal.

Directory of Open Access Journals (Sweden)

Richard Cudney-Bueno

Full Text Available Marine reserves have been advocated worldwide as conservation and fishery management tools. It is argued that they can protect ecosystems and also benefit fisheries via density-dependent spillover of adults and enhanced larval dispersal into fishing areas. However, while evidence has shown that marine reserves can meet conservation targets, their effects on fisheries are less understood. In particular, the basic question of if and over what temporal and spatial scales reserves can benefit fished populations via larval dispersal remains unanswered. We tested predictions of a larval transport model for a marine reserve network in the Gulf of California, Mexico, via field oceanography and repeated density counts of recently settled juvenile commercial mollusks before and after reserve establishment. We show that local retention of larvae within a reserve network can take place with enhanced, but spatially-explicit, recruitment to local fisheries. Enhancement occurred rapidly (2 yrs, with up to a three-fold increase in density of juveniles found in fished areas at the downstream edge of the reserve network, but other fishing areas within the network were unaffected. These findings were consistent with our model predictions. Our findings underscore the potential benefits of protecting larval sources and show that enhancement in recruitment can be manifested rapidly. However, benefits can be markedly variable within a local seascape. Hence, effects of marine reserve networks, positive or negative, may be overlooked when only focusing on overall responses and not considering finer spatially-explicit responses within a reserve network and its adjacent fishing grounds. Our results therefore call for future research on marine reserves that addresses this variability in order to help frame appropriate scenarios for the spatial management scales of interest.

Additionally, 104 individuals were treated with a single dose of albendazole and evaluated over 21 weeks to assess reinfection. Questionnaires were administered to obtain individual and household-level data pertaining to behavior, demography, and socioeconomic status. Risk factors for reinfection after albendazole administration were determined using multiple logistic regression analyses.Results: The prevalence of Ascaris lumbricoides was 73.9% (95% confidence interval [CI] = 71.56%–76.14%. Albendazole was 100% effective, but eggs began to be detected by 9–12 weeks posttreatment, increasing to 100% after 21 weeks. Logistic regression analysis revealed that all individuals from this study had a probability of reinfection of 1.65× each week after treatment. The prevalence of Trichuris trichiura was 57.2% (95% CI = 54.62%–59.77% and chemotherapy was 34.7% effective. The prevalence for other minor gastrointestinal parasites ranged from 0.2% to 29.7%.Conclusion: This was a comprehensive study on gastrointestinal parasites in a rural community from southern Mexico and, to the best of the authors’ knowledge, is the first time that the effect

The seismic movement in the Lake Zone of the Mexico Basin is characterized by long durations and late energy arrivals; many efforts have been made to find the origin of these late waves. In 1997 the Texcoco Seismic Array (TXC) was installed in the former Lake of Texcoco, in the northeastern part of Mexico Basin. It is a natural reserve formed by the same lacustrine clays of the Lake Zone in Mexico City, however we consider TXC as a virgin site as there are no buildings near, and there is almost no human activity. We analyzed 7 earthquakes recorded at TXC in two instrumental arrays, to identify late energy arrivals near the fundamental period and we also analyzed these pulses with F-K method to estimate the phase velocity and its origin.

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.

Some microalgae are economically important in Mexico and the world because they can be potentially toxic. Algal explosive population growths are named harmful algal blooms and are frequently recorded in Mexico. The authors set up potentially toxic microalgae cultures from the Gulf of Mexico (Garrapatas tideland, Barberena river, Carpintero lagoon in Tamaulipas State; Chalchoapan and Catemaco lakes in Veracruz State), from the Mexican Pacific Ocean, Guerrero, Colima and Michoacán States, and from interior water bodies such as Vicente Aguirre dam, Chapultepec lake and several waste water treatment plants. This research is about the diversity and abundance of phytoplankton in relation a specific site because of harmful algal bloom events. Microalgae cultures are useful in order to solve taxonomic problems, to know life cycles, molecular studies, for the study of toxic species, and the isolation of useful metabolites. The cultures for this research are clonal, non-axenic, semi-continuous, 12:12 light/dark photoperiod, 20 ± 1 °C temperature and 90.5 µmol m(-2)s(-1) illumination. Four different culture media were used. This collection is open to the worldwide scientific community as a source of organisms in controlled conditions that can be used as a useful tool for microalgae research work.

The Comprehensive Nuclear Test-Ban-Treaty (CTBT) is a treaty that prohibits all the nuclear explosions by anybody and in any place, either on the terrestrial surface, in the atmosphere, under the sea or underground. From the adoption of this Treaty by the United Nations, Mexico has had interest for its entrance in vigor, as integral part to assure the international peace. For this reason, our country signed the Treaty since it was open in September 24, 1996 and three years later ratified it, due to Mexico is part of the group of necessary countries for their entrance in vigor. During 13 years, the country has been committed and helped to the installation of monitoring stations, actions that allow the strengthening of the International System of Surveillance. The purpose of this work is to divulge the Treaty,its technologies and benefits; and also to diffuse the works realized by Mexico regarding the radionuclides monitoring station and noble gases both certified ones for the CTBT. Besides the radionuclides technology, Mexico has taken charge of the installation and operation of the seismic stations and hydro-acoustics that have been certified too. The radionuclides station Rn-44 located in Guerrero Negro, BCS has two technologies, an automated sampler of suspended particles in air brand Cinderella/ARAME and a noble gases system Sauna used for the particles detection of radioactive material gamma emitting and Xenon radioisotopes product of nuclear assays. Both technologies are transmitting data in real time to the International Center of Data. These technologies are shown in this work. (Author)

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

Science.gov (United States)

Lenhardt, Nils; Götz, Annette E.

2015-04-01

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

Subsidence and surface faulting have affected urban areas in Central Mexico for decades and the process has intensified as a consequence of urban sprawl and economic growth. This process causes substantial damages to the urban infrastructure and housing structures and in several cities it is becoming a major factor to be considered when planning urban development, land use zoning and hazard mitigation strategies in the next decades. Subsidence is usually associated with aggressive groundwater extraction rates and a general decrease of aquifer static level that promotes soil consolidation, deformation and ultimately, surface faulting. However, local stratigraphic and structural conditions also play an important role in the development and extension of faults. Despite its potential for damaging housing, and other urban infrastructure, the economic impact of this phenomena is poorly known, in part because detailed, city-wide subsidence induced faulting risk maps have not been published before. Nevertheless, modern remote sensing techniques are most suitable for this task. We present the results of a risk analysis for subsidence induced surface faulting in two cities in central Mexico: Morelia and Mexico City. Our analysis in Mexico City and Morelia is based on a risk matrix using the horizontal subsidence gradient from a Persistent Scatterer InSAR (Morelia) and SqueeSAR (Mexico City) analysis and 2010 census population distribution data from Mexico's National Institute of Statistics and Geography. Defining subsidence induced surface faulting vulnerability within these urbanized areas is best determined using both magnitude and horizontal subsidence gradient. Our Morelia analysis (597,000 inhabitants with localized subsidence rates up to 80 mm/yr) shows that 7% of the urbanized area is under a high to very high risk level, and 14% of its population (11.7% and 2.3% respectively) lives within these areas. In the case of the Mexico City (15'490,000 inhabitants for the

Insect fauna biodiversity in natural protected areas has not been thoroughly studied. Therefore, the aim of this work was to assess whether and how vegetation types, land management and seasonality influence the diversity of Ichneumonidae (Hymenoptera) in the Ría Lagartos Biosphere Reserve (Mexico). A sampling programme was conducted using Malaise traps from 2008 to 2009 in three vegetation types, each with two conservation zones (core and buffer zones). Three seasons were considered: rainy, dry and north-winds (isolated storms from November to February). A total of 336 species were identified. Rarefaction and Generalized Linear Model indicated higher species richness and abundance, respectively, in the buffer zone of the dry forest; possible explanations for this finding include the intermediate disturbance hypothesis, wherein diversity can be higher in sites where disturbance is not very frequent or very intense, and the 'enemies hypothesis', wherein structural complexity and high plant diversity favour increased predators or, in this case, parasitoids. Diversity was higher during the rainy season, which may have been due to the higher availability of resources. Vegetation and management had a positive impact on the Coc (attack cocoons and pupae) and Myc (attack concealed larvae living in the fruiting bodies of mushrooms) parasitoid guilds. Members of the Coc guild are generalist parasitoids, which may be favoured in complex vegetation with a high richness of potential hosts and non-hosts. The Myc guild requires certain environmental conditions that promote fungal growth, such as humidity, that is absent in the other vegetation types of savannah and coastal dune scrubland.

Identification of sensitive parameters of a tropical forest in Southern Mexico to improve the understanding of C-band radar images

Forest areas cover the 32% of the Mexican territory. Due to their geographical location, Mexico presents heterogeneous climatic and topographic conditions. The country is divided into two different regions: an arid /semiarid zone (North) and a tropical/temperate zone (South). Due to the effects of climate change, Mexico has been affected in two ways. In the North, there has been a desertification of regions as result of the absence of rainfall and a low rate of soil moisture. On the other hand, in the South, there has been an increase in the intensity of rainfall causing serious flooding. Another effect is the excessive deforestation in Southern Mexico. The FAO has determined that Mexico could present one of the highest losses of forest areas mainly in temperate and subtropical ecosystems. The Biosphere Reserve of Calakmul is the protected area with the largest surface of tropical forest in Mexico. The Biosphere Reserve of Calakmul is located in the state of Campeche that the flora and fauna are being affected. The type of vegetation located in the reserve of Calakmul Biosphere is rainforest with high spatial density and highly heterogeneous due to multiple plant species and the impact of human activities in the area. The satellite remote sensing techniques becomes a very useful tool to monitor the area because a large area can be covered. To understand the radar images, the identification of sensitive parameters governing the radar signal is necessary. With the launch of the satellites Radarsat-2, ASAR-Envisat and ALOSPalSAR, significant progress has been done in the interpretation of satellite radar images. Directly applying physical models becomes a problem due to the large number of input parameters in the models, together with the difficulty in measuring these parameters in the field. The models developed so far have been applied and validated for homogeneous forests with low or average spatial density of trees. This is why it is recommended in a comprehensive

Survey of Indian issues in the state of New Mexico relating to uranium mining and milling

International Nuclear Information System (INIS)

Vandevender, S.G.; Barsumian, L.; Gurbaxani, S.H.

1979-11-01

Estimates of Indian uranium resources range from 11 to 50% of the US total resources. About 17% of New Mexico's reserves are known to be on Indian lands. New Mexico has produced almost half of the nation's uranium supply; over half of the known reserves are located within the state. However, the state has virtually no jurisdiction over development of Indian uranium. As a result, economic and environmental impacts on the state are beyond its control. The lack of state and federal control over these impacts is influencing how the Indians allow development to proceed. The impacts of Indian uranium development also influence state control of non-Indian. To the extent that these controls affect the availability of uranium concentrate, DOE needs to understand the issues involved. This issue paper identifies some of the related problems for both the Indians and the state and explores the reasons behind them

According to recent official statistics, in Mexico there is a relation between people’s privileges and their skin color: The lighter, the more privilege. However, social exclusion by racist practices in Mexico has been common practically since its Spanish conquest between 1519 and 1521, in which...... privileges where absorbed and monopolized by European settlers in Mexico (Spanish people: peninsulares) and their descendants (creole: criollos). As a consequence, currently in Mexico, the color of skin affects people’s economic and political privileges and powers in individual and social levels related...

In agreement with the Secretaria de Energia, Mexico consumed daily in year 2000, 1.7 millions of oil barrels and according to numbers of PEMEX the proven reserves to December 31 of that year, ascended to 12,312 million barrels, obviously the consumption and the reserves will change through the time, but making a calculation these reserves will be sufficient only for 20 years, on the other hand according to PEMEX Gas y Petroquimica Basica numbers, the present natural gas reserves are sufficient to supply the demand during 22 years, with these data we can have an approximate calculation of 20 years of fossil fuel supply, to this stage we can name it the period of power transition, when this time interval is over we will have an eminent power crisis and it will be necessary to count already on new power alternatives, which have a sustainable development and which will have to be ready at by the end of the next 20 years. One of the most viable alternatives is obtaining energy from hydrogen, this is the most abundant element in the universe, near 75% is constituted by it, but it is not found in pure state in nature. In order to determine certain state it is necessary to investigate about the processes for the hydrogen obtaining, the reforming of natural gas, the natural gas reserves, the natural gas distribution and the integrated gasification.

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

Chikungunya fever is a tropical vector-borne disease that has been spreading rapidly around the world during the last 10 years, and which has been usually misdiagnosed as dengue. Nowadays, this disease is increasing in Mexico, mainly in the southern and central zones of the country, being significantly more common in women, children and young adults (28% in<20 years of age). The classical presentation includes fever, arthralgia, polyarthritis, back-pain, and skin rashes. Although symptoms and treatment are similar to those for dengue, there are key clinical features to differentiate these two diseases. Copyright © 2016 Hospital Infantil de México Federico Gómez.

Figueroa Vega, F. de la; Boesl, B.

1997-01-01

The article focuses on fossil energy resources in the Andean Group and Mexico, and argues for a dynamic approach to calculating reserves to production ratios. Individual countries are surveyed in terms of estimated reserves of fossil energy, resources, current production rates and future prospects; energy policy options for individual countries are analysed. As a primary objective of energy policy is to ensure security of supply, it is important that that calculations of reserves to production ratios accurately, estimate the desired level of investment in exploration. The calculations need to take into account a variety of parameters, including different energy sources, availability and risk; geographic considerations including proximity, transport, storage capacity and commercial aspects; the competitive and environmental implications of developing indigenous resources; and the use of instruments to establish contingency plans for emergencies

[The control of urban growth in Mexico City. Suppositions regarding poor planning].

Science.gov (United States)

Aguilar, A G; Olvera, G

1991-01-01

Plan of the state of Mexico published in 1986 proposed 2 important programs for controlling urban growth. The territorial reserves program aimed to anticipate the need and make available through purchase, expropriation, or other means sufficient lands for housing to which the lowest income groups would share access. The "Paint Your Line" program establiished physical limits for urban expansion in each of the 17 conurban municipios in the State of Mexico. To date, however, few lands have been set aside for legal acquisition and the Paint Your Line program has been slow in delimiting the areas to be settled. Data from a 1989 study in the municipios of Chalco and Ixtapaluca demonstrate the shortcomings of the programs, which do not address the true processes and agents that control new settlements and especially illegal occupations and which fail to satisfy the needs of low-income population sectors.

Aguilar-Salinas, Carlos A; Rodriguez, Hector Bourges; Oteyza, Ernestina Polo

2017-01-01

The Tenth Nestlé Nutrition Conference, held in Mexico City in November 2014, focused on prevention of type 2 diabetes considering environment, lifestyles, and nutrition. Based on the evidence and recommendations presented during the conference, which are summarized in another article within this supplemental issue, a series of pragmatic proposals to address the environmental, social, and medical factors that have contributed to the growing prevalence of type 2 diabetes in Mexico was formulated. For this article, the actions were organized into 2 conceptual models: one that is applicable for the whole population and the other for at-risk individuals. In addition, each of the items includes the personal views of the authors regarding feasible actions that could be implemented in Mexico. Readers will find a large number of initiatives that could be applied at various levels and for particular subsets of the population. This makes it feasible for improvements to be induced through environmental changes and/or via increased access for at-risk individuals to validated interventions that prevent or delay the onset of diabetes. © The Author(s) 2016.

Nsoesie, Elaine O; Buckeridge, David L; Brownstein, John S

2014-01-22

Alternative data sources are used increasingly to augment traditional public health surveillance systems. Examples include over-the-counter medication sales and school absenteeism. We sought to determine if an increase in restaurant table availabilities was associated with an increase in disease incidence, specifically influenza-like illness (ILI). Restaurant table availability was monitored using OpenTable, an online restaurant table reservation site. A daily search was performed for restaurants with available tables for 2 at the hour and at half past the hour for 22 distinct times: between 11:00 am-3:30 pm for lunch and between 6:00-11:30 PM for dinner. In the United States, we examined table availability for restaurants in Boston, Atlanta, Baltimore, and Miami. For Mexico, we studied table availabilities in Cancun, Mexico City, Puebla, Monterrey, and Guadalajara. Time series of restaurant use was compared with Google Flu Trends and ILI at the state and national levels for the United States and Mexico using the cross-correlation function. Differences in restaurant use were observed across sampling times and regions. We also noted similarities in time series trends between data on influenza activity and restaurant use. In some settings, significant correlations greater than 70% were noted between data on restaurant use and ILI trends. This study introduces and demonstrates the potential value of restaurant use data for event surveillance.

Cactus Nurseries and Conservation in a Biosphere Reserve in Mexico

Directory of Open Access Journals (Sweden)

María T. Pulido

2013-09-01

Full Text Available Documenting how socio-ecosystem conservation knowledge and practice arise and are modified are issues of ethnobiological interest. In the Barranca de Metztitlán Biosphere Reserve (RBBM, plant nurseries, some of which were created as Environmental Management Units (UMAs, have been established to grow and conserve cacti. This paper describes these nurseries, their role in cactus conservation, and the benefits and limitations for the people managing them. The nurseries have helped decrease illegal traffic in cacti and have enabled ex situ conservation of 22 cacti species. Cactus management has changed from extraction to cultivation, as a result of the knowledge and actions of multiple actors. The main limitation is marketing, a recurring problem for non-timber forest products (NTFP. Greater coordination among stakeholders is recommended, such as involvement by non-governmental organizations to improve their probability of success, as well as learning from the experience of other cactus UMAs. Improving the market for cacti is an issue that needs an immediate solution; otherwise conservation efforts could relapse.

United States-Mexico cross-border health insurance initiatives: Salud Migrante and Medicare in Mexico.

Vargas Bustamante, Arturo; Laugesen, Miriam; Caban, Mabel; Rosenau, Pauline

2012-01-01

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

Mexico diabetes prevalence has increased dramatically in recent years. However, no national incidence estimates exist, hampering the assessment of diabetes trends and precluding the development of burden of disease analyses to inform public health policy decision-making. Here we provide evidence regarding current magnitude of diabetes in Mexico and its future trends. We used data from the Mexico National Health and Nutrition Survey, and age-period-cohort models to estimate prevalence and incidence of self-reported diagnosed diabetes by age, sex, calendar-year (1960-2012), and birth-cohort (1920-1980). We project future rates under three alternative incidence scenarios using demographic projections of the Mexican population from 2010-2050 and a Multi-cohort Diabetes Markov Model. Adult (ages 20+) diagnosed diabetes prevalence in Mexico increased from 7% to 8.9% from 2006 to 2012. Diabetes prevalence increases with age, peaking around ages 65-68 to then decrease. Age-specific incidence follows similar patterns, but peaks around ages 57-59. We estimate that diagnosed diabetes incidence increased exponentially during 1960-2012, roughly doubling every 10 years. Projected rates under three age-specific incidence scenarios suggest diabetes prevalence among adults (ages 20+) may reach 13.7-22.5% by 2050, affecting 15-25 million individuals, with a lifetime risk of 1 in 3 to 1 in 2. Diabetes prevalence in Mexico will continue to increase even if current incidence rates remain unchanged. Continued implementation of policies to reduce obesity rates, increase physical activity, and improve population diet, in tandem with diabetes surveillance and other risk control measures is paramount to substantially reduce the burden of diabetes in Mexico.

Tuberculosis is a public health problem across Mexico. This paper aims to select a panel, with a minimum number of repetitive elements (MIRU-VNTR) for genotypic characterization of Mycobacterium tuberculosis (M. tuberculosis) clinical isolates. In this study, a full panel of 24 MIRU-VNTR loci was used to discriminate 65 clinical isolates of M. tuberculosis from three different geographical regions of Mexico. Those loci with the highest discriminatory power were subsequently selected. The panel, including five loci, was obtained by selecting the highest values of allelic diversity among the genotypes obtained. The dendrogram, generated by the panel MIRU-VNTR 5, showed a high discriminatory power with 65 unique genotype profiles and formed clusters according to the geographical region of origin. The panel MIRU-VNTR 5 can be useful for characterizing clinical isolates of M. tuberculosis in Mexico.

A North Sea approach for Mexico?; El marco Mar del Norte para Mexico?

The probable existence of oil and gas deposits in the border territory between Mexico and the United States has waked up an enormous restlessness given the lack of agreements and stipulations on the handling of such deposits; cases like this one have occurred in other parts of the globe and it is indeed the intention of this article to show how the agreement decided on the North Sea can be applied in the case of Mexico. The bilateral characteristics of this agreement conformed by incentives and openings to the market, require the cooperation of different offices and governmental sectors from the federal government to make a series of possible stipulations that regulate the treaty and allow different oil companies a substantial interaction that profits the owners on both sides of the border. In Mexico the responsibility to put in action projects of this type corresponds to the legislative power in complicity with the secretariats of Foreign Affairs and Work. The present action models and the monopoly of Petroleos Mexicanos (PEMEX) in Mexico have only managed to suspend the development of the country in this sector and to maintain the oil industry development in a mediocre and deteriorated level. The benefits of such an adjustment would extend beyond obtaining a bilateral development for the involved countries; nevertheless we remember that the government of the United States is not to the compass of the governments pro-unification of borders. In order to begin the unification of the border regions, Mexico must document the location of border wells, nevertheless even though any agreement could be reached, years would have to pass before PEMEX develops the appropriate technology to operate its part of the deposits.

1992-01-01

This paper provides an overview of the Mexican energy sector and economy,key characteristics of the electric power and energy conservation market, and business opportunities in energy efficiency and conservation, and cogeneration. Mexico is well endowed with a range of fossil fuel and renewable energy resources. The largest energy resource involves hydrocarbons. The country has crude oil reserves of 51 billion barrels (about 55 years' reserve at the 1990 production rate) and natural gas reserves of 72 trillion cubic feet (equivalent to 14.2 billion barrels of crude oil), most of it associated with oil production. Indigenous thermal coal is of low quality and reserves amount to 643 million tons (equivalent to 3.2 billion barrels of crude oil). Large-scale hydropower is the most important renewable energy resource, with a technical potential of about 85 TWH/year (of which about 35% has been developed). About 400 known geothermal fields have a potential for a total installed capacity of 3,900 MW, with only about 18% of the geothermal potential having been developed to date

A first, partial, assessment is included of the low- to medium-temperature geothermal reserves in 20 Mexican States and their aggregate value. The assessment covers about 29.16% of the identified geothermal-surface manifestations in the public database. For reserve assessments, we use the volumetric method, supplemented with Montecarlo simulations and statistics, to quantify inherent uncertainties. Our estimations are presented on a state-by-state basis. We estimate the aggregated reserves of the 20 states as between 7.7 x 1016 and 8.6 x 1016 kJ, with 90% confidence. The most likely reservoir temperatures range between 60-180 degrees Celsius, with a mean of 111 degrees Celsius. Such massive amounts of recoverable energy-and the associated temperatures-are potentially important for the economic development of nearby localities and the nation. [Spanish] En este trabajo se hace una primera estimacion, parcial, de las reservas geotermicas de temperatura intermedia a baja de Mexico. La estimacion incluye 29.16% de las manifestaciones geotermicas identificadas en la base de datos publica utilizada. Para estimar las reservas se utilizo el metodo de volumen, suplementado con simulaciones por el metodo de Montecarlo, con el fin de cuantificar las incertidumbres inherentes. Las estimaciones se presentan estado por estado. Estos resultados indican que las reservas agregadas de los 20 estados considerados estan entre 7.7 x 1016 y 8.6 x 1016 kJ, con 90% de confianza. La distribucion de las temperaturas de yacimiento mas probables varia entre aproximadamente 60 y 180 grados centigrados, con un valor medio de 111 grados centigrados. La enorme magnitud de estas reservas, y sus temperaturas asociadas, son potencialmente importantes para el desarrollo economico de las poblaciones ubicadas en su cercania.

Mexico is a country at the crossroads. It has huge potentials in energy, in natural resources and in human resources. It is currently experiencing one of the most serious crises in its history - economic, ecological, political - and it is making efforts to overcome the problems behind these crises, which may affect us all because of Mexico's importance as energy producer and energy consumer. Mexico is one of the developing countries which has participated actively in finding solutions to the worlds environmental problems not least the problem of climatic changes as a result of increasing energy consumption. Mexico is seeing the consequences at local and national level, and is taking steps to change course. At the same time, it has also expressed interest in participating in international initiatives and cooperation to solve these problem. But Mexico finds itself in a situation not unlike that of many East European countries after the fall of the communist regimes. The old system is tumbling, the will to change is present, but there is a lack of resources. 123 refs., 45 tabs

The Southern Gulf of Mexico is an area highly impacted by crude oil extraction, refining activities and the presence of natural petroleum seepage. Oceanic currents in the Gulf of Mexico continually facilitate the transport of hydrocarbons to lagoons and rivers. This research evaluated hexadecane (HXD) degradation in marine sediment samples from lagoons and rivers that are fed by the Southern Gulf of Mexico, specifically six samples from rivers, three samples from lagoons, and one sample from a marine outfall. The highest rates of biodegradation were observed in sediments from the mouths of the Gonzalez River and the Champotón Lagoon. The lowest consumption rate was found in sediment from the mouth of the Coatzacoalcos River. With regards to the Ostión Lagoon and the Grijalva River, there was a low rate of consumption, but a high efficiency of degradation which took place at the end of the experiments. No correlation was found between the consumption rate and the environmental physicochemical parameters. Copyright © 2018 Elsevier Ltd. All rights reserved.

Major sediment dispersal systems on western Pangea evolved in concert with thermal uplift, rift and drift phases of the Gulf of Mexico Basin, and were influenced by development of a continental arc on Pangea's western margin. Existing literature and preliminary data from fieldwork, sandstone petrology and detrital zircon analysis reveal how major drainages in Mexico changed from Late Triassic through Late Jurassic time and offer predictions for the ultimate destinations of sand-rich detritus along the Gulf and paleo-Pacific margins. Late Triassic rivers drained away from and across the present site of the Gulf of Mexico, which was then the location of a major thermal dome, the Texas uplift of recent literature. These high-discharge rivers with relatively mature sediment composition fed a large-volume submarine fan system on the paleo-Pacific continental margin of Mexico. Predictably, detrital zircon age populations are diverse and record sources as far away as the Amazonian craton. This enormous fluvial system was cut off abruptly near the Triassic-Jurassic boundary by extensive reorganization of continental drainages. Early and Middle Jurassic drainage systems had local headwaters and deposited sediment in extensional basins associated with arc magmatism. Redbeds accumulated across northern and eastern Mexico and Chiapas in long, narrow basins whose locations and dimensions are recorded primarily by inverted antiformal massifs. The Jurassic continental successions overlie Upper Triassic strata and local subvolcanic plutons; they contain interbedded volcanic rocks and thus have been interpreted as part of the Nazas continental-margin arc. The detritus of these fluvial systems is volcanic-lithic; syndepositional grain ages are common in the detrital zircon populations, which are mixed with Oaxaquia-derived Permo-Triassic and Grenville age populations. By this time, interior Pangea no longer supplied sediment to the paleo-Pacific margin, possibly because the

La Cantera Oriente is a shallow freshwater volcanic water body located at an altitude of 2 270 m above sea level in the Ecological Reserve of San Angel Pedregal of Mexico City (Mexico). In order to ensure the conservation of its biological heritage including zooplankton, the present work was undertaken to quantify the seasonal changes in the diversity and density of rotifers and the selected physico-chemical variables during 2013-2014. Qualitative analysis of the zooplankton samples yielded 68 rotifer species which represented 24 genera in 15 families. B rachionus calyciflorus Pallas, 1766, B. quadridentatus Hermann, 1783, Polyarthra vulgaris Carlin, 1943, Lecane closterocerca (Schmarda, 1859) and Keratella cochlearis (Gosse, 1851) were the most common species. Preston plots of species frequency-density revealed that as many as 30% of the rotifer taxa were dominant throughout the year. The species with high population densities were Brachionus quadridentatus, Lecane closterocerca, Keratella cochlearis, and Lepadella patella; their peak densities were 2 000, 1 000, 180 and 90 ind./L, all occurring in summer. Canonical correspondence analysis showed that Platyias quadricornis was related to the concentration of phosphates available in the environment and the conductivity, while B. quadridentatus was positively correlated with chlorophyll- a. The trophic status of the lake was eutrophic based on Chl- a content but oligotrophic with relation to the Brachionus: Trichocerca ratio.

Among male injection drug users (IDUs) in Tijuana, Mexico, U.S. deportation is associated with HIV transmission. Changing drug use behaviors following deportation, including the use of new drugs, may increase HIV risk but are understudied. We identify correlates of trying new drugs following male IDUs' most recent U.S. deportation to Mexico. In 2010, we recruited 328 deported male IDUs in Tijuana, Mexico. Questionnaires collected retrospective data on drug use and other HIV risk behaviors throughout migratory events. Logistic regression identified correlates of trying new drugs/combinations following their most recent deportations. Informed consent was obtained from all participants. Nearly one in six men (n=52, 16%) tried new drugs following their most recent deportation, including heroin (n=31), methamphetamine (n=5), and heroin/methamphetamine combined (n=17). Trying new drugs following deportation was independently associated with U.S. incarceration (adjusted odds ratio [AOR]=3.96; 95% confidence interval [C.I.] 1.78, 8.84), increasing numbers of U.S. deportations (AOR=1.11 per deportation; C.I. 1.03, 1.20), feeling sad following deportation (AOR 2.69; C.I. 1.41, 5.14), and perceiving that one's current lifestyle increases HIV/AIDS risk (AOR 3.91; C.I. 2.05, 7.44). Trying new drugs following U.S. deportation may be related to the unique contexts and stressors experienced by drug-abusing migrants as they attempt to reestablish their lives in Mexico. Findings imply an unmet need for health and social programs to alleviate pre- and post-deportation stressors faced by undocumented and return migrants in the U.S.-Mexico context.

Globally, anal cancer incidence is rare, but is increasing in some world regions. Our objective was to assess differences in anal HPV natural history in three countries. Men aged 18-70 years were recruited from the US (n = 634), Mexico (n = 665), and Brazil (n = 731). Anal specimens were collected every six-months. HPV genotyping was assessed by Linear Array. Anal HPV prevalence was compared using the Fisher's exact test. HPV infection incidence rates (IR) and 95% confidence intervals (CI) were calculated. Any anal HPV prevalence was highest among men from Brazil (24%) compared to Mexico (15%) and the US (15%). When stratified by sexual history, the prevalence of any HPV among MSM/MSMW was 43%, 37%, and 45% and 9%, 12%, and 10% for MSW from Brazil, Mexico, and US, respectively. Any HPV incidence was significantly higher among men from Brazil compared to US men (IRR = 2.4, 95% CI = 1.7-3.4) and comparable between men from Mexico and the US (IRR = 1.2, 95% CI = 0.8-1.8). Men in Brazil and Mexico often have similar, if not higher incidence of anal HPV compared to men from the U.S., and may benefit from gender neutral HPV vaccine policies.

Motivation Factors for Female Entrepreneurship in Mexico

Directory of Open Access Journals (Sweden)

Martha Cantú Cavada

2017-09-01

Full Text Available Objective: The objective of this paper is to analyse motivation factors for female entrepreneurship in Mexico. In the proposed article, the authors discuss the factors which compelled women to start their enterprises in Mexico. Research Design & Methods: Based on in-depth interviews with female entrepreneurs and entrepreneurship experts, the authors show which factors motivated women to start their own business in Mexico. Findings: The study proves that women in Mexico are motivated by a combination of push and pull factors, where the majority of the factors are pull factors. The findings of the study help to conclude that female entrepreneurship development is influenced by different factors including the entrepreneurs’ personal traits, social and economic factors. Due to their conservative traditional attitude, risk adverse tendency, and non-cooperation of family members, etc. women entrepreneurs are sometimes deterred to start a business in Mexico. Implications & Recommendations: It is necessary to raise the awareness of different factors that promote female entrepreneurship in Mexico. Governmental programmes which support female entrepreneurship, business incubators, and networking could be very helpful for women when starting their own business. Contribution & Value Added: The originality of this work lies in studying motivational factors for female entrepreneurship in Mexico. The Mexican society faces a big revolution towards female entrepreneurship. Based on the change of family structure and traditions, women nowadays are having more opportunities to develop as entrepreneurs.

Competing actors in the climate change arena in Mexico: A network analysis.

Science.gov (United States)

Ortega Díaz, Araceli; Gutiérrez, Erika Casamadrid

2018-06-01

This paper analyzes the actors in the climate change arena and their influence in directing Mexico toward policies that decrease greenhouse gas emissions, such as the carbon tax and climate change law. The network analysis of the agreement of these laws and public policies in Mexico is a lesson for any country that is in the process of designing and adopting environmental laws. The research is performed using a network analysis that is derived from interviews with various main actors and a discourse analysis of the media. Results show that actors do not coordinate their efforts-they meet frequently but in different inter-ministerial commissions-and do not enforce the same policies. The actors in the industry have formed strong coalitions against the carbon tax and the General Law on Climate Change, whereas international institutions have formed coalitions that support these policies and laws.

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.

Pertussis infections and vaccinations in Bolivia, Brazil and Mexico from 1980 to 2009.

Science.gov (United States)

McCormick, Colleen M; Czachor, John S

2013-01-01

Global coverage with three doses of the diphtheria, tetanus and pertussis vaccine (DTP3) increased from less than 5% in 1974 to 82% in 2009 due to worldwide focus on universal vaccination. Nonetheless, pertussis remains the fifth-leading cause of vaccine-preventable deaths. This study examines DTP3 vaccination from 1980 through 2009 in three countries within Latin America, Bolivia, Brazil and Mexico, selected for their distinct health care systems and vaccination strategies. Similar to global trends, these nations have achieved dramatic improvements in pertussis immunization. In Bolivia, immunization rates increased from 11% to 85%; in Brazil, rates increased from 37% to 97%; and in Mexico, the immunization rates increased from 44% to 72%. Pertussis infections have concomitantly decreased from 1980 to 2009. In Bolivia, cases decreased from 44.4 per 100,000 people to zero reported cases. In Brazil, the incidence decreased from 37.6 to 0.5 cases per 100,000. The incidence in Mexico decreased from 8.2 to 0.5 cases per 100,000. In order to increase vaccination rates further, health systems must continue to raise awareness about disease prevention, expand health surveillance systems, and improve access to health services.

Health technology assessment in Mexico.

Science.gov (United States)

Gómez-Dantés, Octavio; Frenk, Julio

2009-07-01

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.

Historical explanation of the origin of the herpetofauna of Mexico Explicación histórica del origen de la herpetofauna de México

Full Text Available A hypothesis of historical area relationships for Mexico, Central, and South America was investigated by a cladistic biogographic analysis using 10 taxon cladograms of the herpetofauna of Mexico. A hypothesis is presented based on previous narrative biogeographic scenarios and compared with the general area cladograms (GACs obtained using reconciled trees of COMPONENT 2.0 and Brooks Parsimony Analysis (BPA. For tree reconciliation, 1 000 trees were saved after the analysis. BPA yielded 18 GACs (CI = 0.805, RI= 0.549. The GAC derived from tree reconciliation is more or less pectinate and has only 3 groups of 2 areas each. These groups consist of the Chihuahuan and Sonoran deserts as sister areas on the one hand (DCHI, DSON, and the Sierra Madre Oriental and Occidental as sister areas on the other (SMOR, SMOC. This latter clade is sister to the Chihuahuan and Sonoran desert clade. The third group has the Transvolcanic Belt and Sierra Madre del Sur as sister areas (TVA, SMEX. The GAC obtained by BPA showed 4 main groups of areas: the first is comprised of the Pacific coast of Mexico and the Balsas Depression (PCBAL, the Sierra Madre del Sur (SMEX, and the Transvolcanic Belt (TVA; the second group includes the Sierra Madre Oriental (SMOR, Sierra Madre Occidental (SMOC, Sonoran (DSON and Chihuahuan deserts (DCHI; the third comprised the Highlands of Chiapas and Guatemala (CHIG, the Eastern Lowlands, on the Atlantic coast (ELL and the Semiarid Lands of Tamaulipas-Texas (TAMS; the fourth group contains the Western Lowlands, in the Pacific coast (WLL and northern South America (SA; the Talamanca Ridge (TALA is isolated at the base of the 3 first groups.

Full Text Available The article describes the problem of organized crime in modern Mexico. It addresses the activities of criminal clans, which profoundly evolved since the 1930s. The USMexican extensive border length and the stable demand for drugs in the United States leads to the continuous flow of illegal migrants and drugs from Mexico to the US and American firearms back to Mexico. First, the authors address the issue of interconnectedness of crime in the neighboring countries. Second, they describe the geographical distribution of crime activity. It shows the influence of organized crime on the political life oin Mexico and ways of its adaptation to law enforcement pressure, namely division and disaggregation. The authors state that the fight against organized crime was ineffective in Mexico in 2006-2012, because it ignored political and cultural realities, it used exclusively force and almost did not involve civil society. In addition, it only increased the level of violence in the country and contributed to the growth of corruption in the ranks of law enforcement. Moreover, it increased the level of violence in the country and contributed to the growth of corruption in the ranks of law enforcement. Many of its components had a pronounced «pre-election» character, aimed at attracting the voter with the promise of an «early and decisive victory» over criminals. The article proposes new approach to the problem of organized crime in Mexico. To start with, government should refuse to use unilateral, as well as politicized and opportunistic actions. The involvement of civic society is of ultimate importance.

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.

Flores-Estrella, H. C.; Yussim, S.; Lomnitz, C.

2004-12-01

The effects of the Michoacan earthquake (19th September, 1985, Mw 8.1) in Mexico City caused a significant change in the political, social and scientific history, as it was considered the worst seismic disaster ever lived in Mexico. Since then, numerous efforts have been made to understand and determine the parameters that caused the special features registered. One of these efforts had began on 1960 with the work by Marsal and Masari, who published the Mexico Valley seismological and geotechnical zonification (1969), based on gravimetric and shallow borehole data. In this work, we present a revision of the studies that proposed the zonification, a description of the valley geology, and basing on it we propose a new zonification for Mexico Valley.

Reserves, the extraction of petroleum and the number of wells in the countries of the world

Energy Technology Data Exchange (ETDEWEB)

Pluzhnikov, B I

1981-01-01

The greatest percentage increase in the proven reserves of petroleum for the beginning of 1980 (in percentage) was noted in the Philippines (158.8), the Netherlands (100), France (68.3), Oman (47.4), and Bolivia. A decrease in the reserves of petroleum was noted in Marocco (-40.5%), Israel (-20.3%), Japan (-15.6%), and so forth. Proven reserves of petroleum are as follows in billions of tons: Saudia Arabia, 23; Kuwait, 10; Iran, 5.5; Mexico, 4.5. The extraction of oil in the first half of 1980 amounted to 243 million tons in Saudia Arabia; 213 million tons in the United States; 86 million tons in Iraq; 55 million tons in Venezuela; 53 million tons in Nigeria; 52 million tons in Iraq; 47 million tons in Kuwait; 45 million tons in Libya; and 40 million tons in Great Britain.

[Food habits and winter diet of Charadrius melodus (Charadriiformes: Charadriidae) in Boca Ciega, Tamaulipas, Mexico].

Science.gov (United States)

Banda-Villanueva, Iris; Contreras-Lozano, Jorge; Garcia-Salas, Juan; González-Páez, Hugo

2013-06-01

The Piping Plover (Charadrius melodus) is a migratory endangered species that arrives, along with a great number of other winter migratory birds, to Boca Ciega every year. In spite of the importance of this ecosystem, these species, are threatened by the current habitat change caused by the dredging activities in the area. With the aim to generate new information about the importance of this area during winter, we studied C melodus activities during the winter season in Laguna Madre, from December 2009 to March 2010. Our objectives were: 1) determine the importance of the area during winter, 2) describe C. melodus ethology, feeding substrate preferences and food items, 3) to analyze and describe the sympatric diversity associated with C melodus. A total of ninety nine individuals were observed during the monitoring. The Cochran and Kendall test showed a high significance of the species with the substrate and signs tests using a binomial distribution that indicated a high preference for algal type of substrate. The highest activity recorded for this species during this winter season was feeding. The principal food items found in sediments were larvae of Diptera: Chironomidae and Ephydridae. The sympatric species of C. melodus were two families of Charadriiforms: Scolopacidae (nine species) and Charadriidae (two species). We concluded that this is an important area for feeding, protection and rest sites for this species, and its protection and management is recommended.

Occurrence and amount of microplastic ingested by fishes in watersheds of the Gulf of Mexico.

Science.gov (United States)

Phillips, Melissa B; Bonner, Timothy H

2015-11-15

Ingestion of microplastics by fishes could be an emerging environmental crisis because of the proliferation of plastic pollution in aquatic environments. Microplastics in marine ecosystems are well documented, however only one study has reported percent occurrence of microplastics in freshwater fishes. The purpose of this study was to quantify the occurrences and types of microplastics ingested by fishes within several freshwater drainages of the Gulf of Mexico and an estuary of the Gulf of Mexico. Among 535 fishes examined in this study, 8% of the freshwater fishes and 10% of the marine fishes had microplastics in their gut tract. Percentage occurrence of microplastics ingested by fishes in non-urbanized streams (5%) was less than that of one of the urbanized streams (Neches River; 29%). Percent occurrence of microplastics by habitat (i.e., benthic, pelagic) and trophic guilds (herbivore/omnivore, invertivore, carnivore) were similar. Low but widespread occurrences among drainages, habitat guilds, and trophic guilds indicate proliferation of plastic pollution within watersheds of the Gulf of Mexico, but consequences to fish health are unknown at this time.

Modeling lost production from destroyed platforms in the 2004-2005 Gulf of Mexico hurricane seasons

International Nuclear Information System (INIS)

Kaiser, Mark J.; Yu, Yunke; Jablonowski, Christopher J.

2009-01-01

Hurricanes Ivan, Katrina, and Rita passed through the Gulf of Mexico during 2004 and 2005 and resulted in the largest number of destroyed and damaged offshore oil and gas structures in the history of Gulf operations. In the final official government assessment, a total of 126 platforms were destroyed and over 183 structures were identified as having extensive damage. Production associated with wells and structures that are not redeveloped are classified as lost. The purpose of this paper is to derive functional relations that describe the likely contribution the collection of destroyed assets would have made to future production in the Gulf of Mexico. We estimate that the total remaining reserves from the set of destroyed structures range in value between 1.3 and 4.5 billion depending on the assumptions employed. We summarize the impact of the storms on the Gulf of Mexico oil and gas infrastructure and discuss the main issues involved in redevelopment decision making. A meta-model analytic framework is applied to perform sensitivity analysis and to explore the interactions of assumptions on model output. A discussion of the limitations of the analysis is presented. (author)

Martin Parr in Mexico: Does Photographic Style Translate?

Directory of Open Access Journals (Sweden)

Timothy R. Gleason

2011-11-01

Full Text Available This study analyzes Martin Parr’s 2006 photobook, Mexico. Parr is a British documentary photographer best known for a direct photographic style that reflects upon “Englishness.”Mexico is his attempt to understand this foreign country via his camera. Mexico, as a research subject, is not a problem to solve but an opportunity to understand a photographer’s work. Parr’s Mexico photography (technique, photographic content, and interest in globalization, economics, and culture is compared to his previous work to explain how Parr uses fashion and icons to represent a culture or class. This article argues Parr’s primary subjects, heads/hats, food, and Christs, are photographed without excessive aesthetic pretensions so that the thrust of Parr’s message about globalization can be more evident:Mexico maintains many of its traditions and icons while adopting American brands.

Gulf of Mexico deep-water

Ott, G.L.

1998-01-01

The deepwater Gulf of Mexico, an emerging basin with 20 BBOE resource potential, was discussed. Technologies are advancing and development options are increasing within the Gulf of Mexico deepwater environment. Deepwater offers significant rate potentials leading to strong cash flows. The projected steep rate of resources captured in the next five years show that there is a short window of opportunity to establish a business position. The major production variables are development costs and cycle time. There is a definite market for Gulf of Mexico products because U.S. energy demand is expected to outstrip U.S. supply. Present infrastructure is capable of moving large volumes of gas into major U.S. markets, but with the large number of projects currently underway, especially in the United States, supply could exceed capacity. 1 tab., 16 figs

Threats to security and ischaemic heart disease deaths: the case of homicides in Mexico.

Science.gov (United States)

Lee, Eileen H; Bruckner, Tim A

2017-02-01

Ischaemic heart disease (IHD) ranks as the leading cause of death worldwide. Whereas much attention focuses on behavioural and lifestyle factors, less research examines the role of acute, ambient stressors. An unprecedented rise in homicides in Mexico over the past decade and the attendant media coverage and publicity have raised international concern regarding its potential health sequelae. We hypothesize that the rise in homicides in Mexico acts as an ecological threat to security and elevates the risk of both transient ischaemic events and myocardial infarctions, thereby increasing IHD deaths. We applied time-series methods to monthly counts of IHD deaths and homicides in Mexico for 156 months spanning January 2000 to December 2012. Methods controlled for strong temporal patterns in IHD deaths, the unemployment rate and changes in the population size at risk. After controlling for trend and seasonality in IHD deaths, a 1-unit increase in the logged count of homicides coincides with a 7% increase in the odds of IHD death in that same month (95% confidence interval: 0.04 - 0.10). Inference remains robust to additional sensitivity checks, including a state-level fixed effects analysis. Our findings indicate that the elevated level of homicides in Mexico serves as a population-level stressor that acutely increases the risk of IHD death. This research adds to the growing literature documenting the role of ambient threats, or perceived threats, to security on cardiovascular health. © The Author 2016; all rights reserved.

2017-11-01

The State of Baja California (BC) exhibits the highest incidence and prevalence rates of tuberculosis (TB), and multidrug-resistant TB (MDR-TB) in Mexico. However information about the circulation of M. tuberculosis lineages in BC and Mexico as a whole is limited. Here, we describe the genetic relationship and genetic diversity among M. tuberculosis clinical isolates (n=140) collected in BC between October 2009 and April 2011 with other regions of Mexico, the United States, and Latin America. All specimens were genotyped based on 24 mycobacterial interspersed repetitive units (MIRU)-variable number of tandem repeats (VNTR) loci. Population structure and minimum spanning tree (MST) analyses were used to assess the genetic diversity and distribution of BC isolates in comparison to USA and South America strains. Among the nine lineages observed, LAM, Haarlem and S were the most frequent identified in BC. Population structure analysis clustered most BC isolates (41%) into three distinctive groups that included strains from San Diego and South America, whereas other BC strains (22%) clustered with other Mexican strains. A subset of isolates (12%) seemed to be autochthonous of BC, while 25% were cosmopolitan and grouped into multiple clusters. It is highly likely that the TB genetic structure observed in BC is due to human migration. Additional studies are required to determine the mechanism involved in the phylogeographic distribution of M. tuberculosis in Mexico. Implementation of domestic molecular TB surveillance programs is required to better understand the molecular epidemiology of TB not only in the region but at the national level.

What is the level of household gun ownership in urban Mexico? An estimate from the first Mexican survey on gun ownership 2017.

Science.gov (United States)

Perez Esparza, David; Hemenway, David

2017-12-20

Gun violence has increased in Mexico since the mid-2000s, but little is known about patterns of gun ownership. We examine the size and composition of the privately held urban firearm stock in Mexico, motivations for ownership, and attitudes about gun laws. To this end, a household telephone survey of 1361 adults living in nine Mexican cities was conducted in the summer of 2017. We find that few urban Mexican households contain guns. Most of those who report ownership possess one gun, having purchased it recently for self-defense. Few urban Mexican citizens plan to purchase a gun in the future. Respondents are more likely to believe that crime in Mexico would increase if guns were allowed in more places (ie, workplaces and motor vehicles). Evidence suggests urban Mexico has relative low rates of firearm ownership. Few city dwellers plan on obtaining a firearm in the near future. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

The economic impact of Sandia National Laboratories on central New Mexico and the state of New Mexico fiscal year 1997

International Nuclear Information System (INIS)

Lansford, R.R.; Nielsen, T.G.; Schultz, J.; Adcock, L.D.; Gentry, L.M.

1998-01-01

Sandia National Laboratories (SNL) was established in 1949 to perform the engineering development and ordnance responsibilities associated with nuclear weapons. By the early 1960's the facility had evolved into an engineering research and development laboratory and became a multiprogram laboratory during the 1970s. Sandia is operated for the US Department of Energy by the Sandia Corporation, a wholly-owned subsidiary of Lockheed Martin, Incorporated. For several years, the US Department of Energy (DOE) Albuquerque Operations Office (AL) and New Mexico State University (NMSU) have maintained an inter-industry, input-output model with capabilities to assess the impacts of developments initiated outside the economy such as federal DOE monies that flow into the state, on an economy. This model will be used to assess economic, personal income and employment impacts of SNL on central New Mexico and the state of New Mexico. For this report, the reference period is FY 1997 (October 1, 1996, through September 30, 1997) and includes two major impact analyses: the impact of SNL activities on central New Mexico and the economic impacts of SNL on the state of New Mexico.

McKenna, J.J. (PricewaterhouseCoopers Securities, Houston, TX (United States))

1999-01-01

A series of brief notes accompanied this presentation which was divided into seven sections entitled: (1) capital markets update, (2) Mexican financial market update, (3) financing options in the energy industry, (4) the Venezuelan experience at La Apertura, (5) private and strategic equity alternatives, (6) Pricewaterhouse Coopers Securities, and (7) Mexico energy 2005 prediction. The paper focused on how the financial crisis and merger activity in Latin America will impact electricity reform in Mexico. It was noted that under Mexico's Policy Proposal for Electricity Reform of the Mexican Electricity Industry, the financial community will seek to back companies in power generation, transportation and distribution. The difficulty of financing government businesses undergoing privatization was also discussed with particular emphasis on the challenge of accepting political and regulatory risks. The Latin private equity market and Canadian investment in Mexico was also reviewed. Since NAFTA (North American Free Trade Agreement) went into affect in 1994, Canadian investment in Mexico has more than tripled. Canadian companies have invested more than C$1.7 billion in Mexico since NAFTA. Pricewaterhouse Coopers Securities is a global investment bank which sees large opportunities in the Mexican energy market. They predict that in five years, Mexico will experience a gradual liberalization of the oil and gas sector, and a full liberalization of the gas pipeline and distribution business and the power generation, transmission and distribution business. 3 figs.

Epidemic risk from cholera introductions into Mexico.

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.

Policies to reduce carbon emissions from Mexico

International Nuclear Information System (INIS)

Mendoza, Y.

1991-01-01

The two long-term scenarios carried out for Mexico attempt to paint a picture of carbon emissions and energy use in the year 2025. The scenarios reveal that Mexico's current energy path is not optimal; the energy-intensity indicators show an increasing reliance on petroleum products and electricity over the next 40 years. Thus, Mexico must embark on a program of energy conservation in the near future. Mexico recently has undertaken several energy conservation efforts. The Mexican government implemented a National Program for Energy Modernization. This program identifies the promotion of energy conservation in Mexico as one of its top priorities between 1990 and 1994. It incorporates a number of actions geared at improving energy conservation, including: establishing pricing policies which pay special attention to electricity tariffs; setting aside budget appropriations for energy-savings programs; carrying out an energy diagnosis in the transportation and industrial sectors; promoting cogeneration and new legislation in this field; setting efficiency standards for equipment; initiating a public education campaign to inform people about energy conservation; promoting the participation of research institutes and consulting firms in the research of the technological aspects of energy-saving measures; and creating agreement with industrial and commerce associations

Petroleum Refining and its Economic and Technological Impact for the Production of Gasoline in Mexico to 2030

Directory of Open Access Journals (Sweden)

Granados-Hernández Elías

2013-10-01

Full Text Available Gas imports in Mexico have increased in the last few years. Nowadays Mexico has no capacity to meet the demands of this fuel in the next twenty years. In this paper we analyze several oil refining projections that enable the oil supply in Mexico until year 2030, taking into consideration four types of refineries, processing the produc- tion of pure oils in the country, using four mixtures of the higher reserve, consider- ing an import to meet the demand of fuel and once met consider exportation. Modeling was carried out analyzing the volume of refined oil and the required in- vestment, based on the kind of refinery and on the processing units that characterize it. As it was mentioned before, there are different refining projections to meet the demand of gas, but considering that the main oil production in Mexico is heavy. The simulated projection with this type of oil would require a higher volume in the exis- tent refineries in the country to meet that demand. Besides, considering the kind of refinery (out of four, the volumes to refine will be less, if very complex refineries are used. However, the cost of investment in this technology would be higher, consider- ing that new refineries will be built in a near future to meet the fuel demands.

2013-10-01

The Comprehensive Nuclear Test-Ban-Treaty (CTBT) is a treaty that prohibits all the nuclear explosions by anybody and in any place, either on the terrestrial surface, in the atmosphere, under the sea or underground. From the adoption of this Treaty by the United Nations, Mexico has had interest for its entrance in vigor, as integral part to assure the international peace. For this reason, our country signed the Treaty since it was open in September 24, 1996 and three years later ratified it, due to Mexico is part of the group of necessary countries for their entrance in vigor. During 13 years, the country has been committed and helped to the installation of monitoring stations, actions that allow the strengthening of the International System of Surveillance. The purpose of this work is to divulge the Treaty,its technologies and benefits; and also to diffuse the works realized by Mexico regarding the radionuclides monitoring station and noble gases both certified ones for the CTBT. Besides the radionuclides technology, Mexico has taken charge of the installation and operation of the seismic stations and hydro-acoustics that have been certified too. The radionuclides station Rn-44 located in Guerrero Negro, BCS has two technologies, an automated sampler of suspended particles in air brand Cinderella/ARAME and a noble gases system Sauna used for the particles detection of radioactive material gamma emitting and Xenon radioisotopes product of nuclear assays. Both technologies are transmitting data in real time to the International Center of Data. These technologies are shown in this work. (Author)

Analysis of bacterial metagenomes from the Southwestern Gulf of Mexico for pathogens detection.

Science.gov (United States)

Escobedo-Hinojosa, Wendy; Pardo-López, Liliana

2017-07-31

Little is known about the diversity of bacteria in the Southwestern Gulf of Mexico. The aim of the study illustrated in this perspective was to search for the presence of bacterial pathogens in this ecosystem, using metagenomic data recently generated by the Mexican research group known as the Gulf of Mexico Research Consortium. Several genera of bacteria annotated as pathogens were detected in water and sediment marine samples. As expected, native and ubiquitous pathogenic bacteria genera such as Burkolderia, Halomonas, Pseudomonas, Shewanella and Vibrio were highly represented. Surprisingly, non-native genera of public health concern were also detected, including Borrelia, Ehrlichia, Leptospira, Mycobacterium, Mycoplasma, Salmonella, Staphylococcus, Streptococcus and Treponema. While there are no previous metagenomics studies of this environment, the potential influences of natural, anthropogenic and ecological factors on the diversity of putative pathogenic bacteria found in it are reviewed. The taxonomic annotation herein reported provides a starting point for an improved understanding of bacterial biodiversity in the Southwestern Gulf of Mexico. It also represents a useful tool in public health as it may help identify infectious diseases associated with exposure to marine water and ingestion of fish or shellfish, and thus may be useful in predicting and preventing waterborne disease outbreaks. © FEMS 2017.

[Central American migrants' sexual experiences and rights in their transit to the USA].

Science.gov (United States)

Infante, César; Silván, Rubén; Caballero, Marta; Campero, Lourdes

2013-07-01

To explore the causes and circumstances that determine the way in which migrants experience their sexuality and how this impacts their sexual rights. Qualitative study conducted between April 2009 and July 2010 in Chiapas, Oaxaca, San Luis Potosí, and Tamaulipas. We conducted 22 in-depth interviews to migrants in transit and to ten different key actors. For the analysis we used elements of grounded theory. Migrants know and identify the risks they may encounter in their transit but have scarce access to services to effectively exercise their sexual and reproductive rights. Their vulnerability makes them internalize and accept the violence enacted on them as part of their destiny and as what they must suffer in order to reach the USA. Violence, including sexual violence, determines much of the experiences of their transit through Mexico. Differences between groups and between male and female migrants are determined by gender inequalities and power.

Habitat Suitability Index Models: Forster's tern (breeding) - Gulf and Atlantic coasts

Science.gov (United States)

Martin, Richard P.; Zwank, Phillip J.

1987-01-01

The nesting range of Forster's terns hosts three allopatric breeding populations. The first and most important breeding area, in terms of the number of nes t i ng pairs, includes the western guIf coas t from the Louisiana-Mississippi border to northern Tamaulipas, Mexico (American Ornithologists' Union [AOUJ 1983). In addition, small numbers of Forster's terns have nested in Mobile County, Alabama (Imhof 1976). Although this species has not been recorded nesting in Mississippi (J. Jackson, Mississippi State University, Starkville; pers. comm.), it is observed in the coastal regions of that State every summer, and several thousand nest in adjacent Louisiana (Portnoy 1977; Clapp et ale 1983). The two largest colonies of Forster's terns documented in the literature were both in Louisiana: one of 2,750 pairs in Lake Borgne on the Louisiana-Mississippi border and one of 2,263 pairs in Calcasieu Lake (Portnoy 1977).

Mexico: a solar future

International Nuclear Information System (INIS)

2016-01-01

Immersed in the global price instability of fossil fuels and with an upsurge in renewables as the agent for development, countries like Mexico, that largely depend on this resource to generate income and whose national electrical energy generation mainly comes from these fuels, find themselves obliged to take decisions that allow them to maintain their appeal compared to other emerging markets. In this decision-making process, Mexico has been slow to implement its long-awaited Energy Reform that incentivises direct foreign investment and avoids the monopolies that have until recently prevailed in the Mexican energy and electricity sector.

registro, control y erradicación de especies invasoras en la reserva de Biosfera Sierra de Huautla y áreas de protecciónde la biodiversidad en MéxicoHistorical presence of invasive fish in the Biosphere Reserve Sierra de Huautla, Mexico. The effects of invasive species on native ecosystems are varied, and these have been linked to the disappearance or decline of native fauna, changes in community structure, modification of ecosystems and as vectors of new diseases and parasites. Besides, the development of trade in species for ornamental use has contributed significantly to the import and introduction of invasive fish in some important areas for biodiversity conservation in Mexico, but the presence of these species is poorly documented. In this study we analyzed the fish community in the Biosphere Reserve Sierra de Huautla by looking at diversity changes in the last 100 years. For this, we used databases of historical records and recent collections for five sites in the Amacuzac river, along the Biosphere Reserve area. We compared the values of similarity (Jaccard index between five times series (1898-1901, 1945-1953, 1971-1980, 1994-1995 and 2008-2009, and we obtained values of similarity (Bray-Curtis between the five sites analyzed. In our results we recognized a total of 19 species for the area, nine non-native and ten native, three of which were eliminated for the area. Similarity values between the early days and current records were very low (.27; the major changes in the composition of the fauna occurred in the past 20 years. The values of abundance, diversity and similarity among the sampling sites, indicate the dominance of non-native species. We discuss the role of the ornamental fish trade in the region as the leading cause of invasive introduction in the ecosystem and the possible negative effects that at least four non-native species have had on native fauna and the ecosystem (Oreochromis mossambicus, Amatitlania nigrofasciata, Pterygoplichthys

As part of this effort, the Sandia Design Assistance Center (DAC) and the solar energy program staff at Instituto de Investigaciones Electricas (IIE) in Cuernavaca, Mexico, recently reached agreement on a framework for mutually beneficial technical collaboration on the monitoring and field evaluation of renewable energy systems in Mexico, particularly village-scale hybrid systems. This trip was made for the purpose of planning the details for the joint installation of a data acquisition system (DAS) on a recently completed PV/Wind/Diesel hybrid system in the village of Xcalac on the Southeast coast of the state of Quintana Roo, Mexico. The DAS installation will be made during the week of March 15, 1993. While in Mexico, discussions were also held with personnel from.the National Autonomous University of Mexico (UNAM) Solar Energy Laboratory and several private sector companies with regard to renewable energy project activities and technical and educational support needs in Mexico.

Are Private Reserves Effective for Jaguar Conservation?

Directory of Open Access Journals (Sweden)

Carmina E Gutiérrez-González

Full Text Available We present the first study of density and apparent survival for a jaguar (Panthera onca population in northern Mexico using 13 years of camera trap data from 2000 to 2012. We used the Barker robust design model which combines data from closed sampling periods and resight data between these periods to estimate apparent survival and abundance. We identified 467 jaguar pictures that corresponded to 48 jaguar individuals. We included camera type and field technician as covariates for detection probabilities. We used three covariates to evaluate the effect of reserve on jaguar apparent survival: i private reserve creation ii later reserve expansions, and iii cattle ranches' conservation activities. We found that the use of digital cameras in addition to film cameras increased detection probability by a factor of 6x compared with the use of only film cameras (p = 0.34 ± 0.05 and p = 0.05 ± 0.02 respectively in the closed period and more than three times in the open period (R = 0.91 ± 0.08 and R = 0.30 ± 0.13 mixed and film cameras respectively. Our availability estimates showed no temporary emigration and a fidelity probability of 1. Despite an increase of apparent survival probability from 0.47 ± 0.15 to 0.56 ± 0.11 after 2007, no single covariate explained the change in these point estimates. Mean jaguar density was 1.87 ± 0.47 jaguars/100 km2. We found that 13 years of jaguar population monitoring with our sampling size were not enough for detecting changes in survival or density. Our results provide a baseline for studies evaluating the effectiveness of protected areas and the inclusion of ranch owners in jaguar conservation programs and long-term population viability.

Large recovery of fish biomass in a no-take marine reserve.

Directory of Open Access Journals (Sweden)

Octavio Aburto-Oropeza

Full Text Available No-take marine reserves are effective management tools used to restore fish biomass and community structure in areas depleted by overfishing. Cabo Pulmo National Park (CPNP was created in 1995 and is the only well enforced no-take area in the Gulf of California, Mexico, mostly because of widespread support from the local community. In 1999, four years after the establishment of the reserve, there were no significant differences in fish biomass between CPNP (0.75 t ha(-1 on average and other marine protected areas or open access areas in the Gulf of California. By 2009, total fish biomass at CPNP had increased to 4.24 t ha(-1 (absolute biomass increase of 3.49 t ha(-1, or 463%, and the biomass of top predators and carnivores increased by 11 and 4 times, respectively. However, fish biomass did not change significantly in other marine protected areas or open access areas over the same time period. The absolute increase in fish biomass at CPNP within a decade is the largest measured in a marine reserve worldwide, and it is likely due to a combination of social (strong community leadership, social cohesion, effective enforcement and ecological factors. The recovery of fish biomass inside CPNP has resulted in significant economic benefits, indicating that community-managed marine reserves are a viable solution to unsustainable coastal development and fisheries collapse in the Gulf of California and elsewhere.

Neuropsychology in Mexico.

Science.gov (United States)

Ostrosky Shejet, Feggy; Velez Garcia, Alicia

2016-11-01

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.

Behavioral intervention in the treatment of obesity in children and adolescents: implications for Mexico.

Science.gov (United States)

Jelalian, Elissa; Evans, E Whitney

2017-01-01

Pediatric obesity is a worldwide health epidemic affecting both developed and developing countries. Mexico ranks second to the United States in rates of pediatric obesity. Obesity among youth has immediate and long-term consequences on physical and psychosocial development, including cardiovascular, respiratory, and health-related quality of life. Eventual amelioration of this epidemic will require change at the level of the family and community, along with policy initiatives to support healthier eating and activity habits. Evidence-based interventions for overweight/obese youth include family-based lifestyle programs that incorporate attention to diet quantity and quality, physical activity, sedentary behavior, and behavioral strategies to support change. While much of this research has been conducted in the United States, several recent studies suggest the efficacy of similar approaches for youth in Mexico. © The Author(s) 2016.

Conch, Cooperatives, and Conflict: Conservation and Resistance in the Banco Chinchorro Biosphere Reserve

Directory of Open Access Journals (Sweden)

Full Text Available In theory, biosphere reserves link biodiversity conservation with development, primarily through sustainable resource utilisation, and alternative, conservation-compatible economies in the buffer and transition zones outside the core area. Successful management should reduce pressure on natural resources within its core area as well as enable local communities to participate in the management of buffer zone resources in a sustainable manner. The Banco Chinchorro Biosphere Reserve was declared in 1996 to protect coral reefs and marine biodiversity, while also enabling fishing cooperatives to maintain their livelihoods based upon the sustainable extraction of lobster, conch, and scalefish. In 2004, eight years after the Reserve′s declaration, Mexican authorities struggled to control marine resource use in the reserve, especially the extraction of queen conch (Strombus gigas. This article provides an overview of the long struggle to conserve queen conch populations in the area. Particular attention is paid to describing the various forms of resistance fishermen employed to counter the increasing regulation and vigilance that accompanied the creation of the Banco Chinchorro Biosphere Reserve. This case chronicles the resistance to regulation and interpersonal violence that erupts when entrenched attitudes and practices are confronted with increasing surveillance. Thus, what was observed in the Banco Chinchorro Biosphere Reserve parallels other research that depicts the forms of resistance to conservation that local people enact when confronted with conservation interventions. Finally, the plight of queen conch in the Banco Chinchorro Biosphere Reserve clearly reflects the conflicts and difficulties found across Mexico in the implementation of the biosphere reserve model.

Lipid reserves and immune defense in healthy and diseased migrating monarchs Danaus plexippus

Full Text Available Recent studies suggest that the energetic demands of long-distance migration might lower the pool of resources available for costly immune defenses. Moreover, migration could amplify the costs of parasitism if animals suffering from parasite-induced damage or depleted energy reserves are less able to migrate long distances. We investigated relationships between long-distance migration, infection, and immunity in wild fall-migrating monarch butterflies Danaus plexippus. Monarchs migrate annually from eastern North America to central Mexico, accumulating lipids essential for migration and winter survival as they travel southward. Monarchs are commonly infected by the debilitating protozoan parasite Ophryocystis elektroscirrha (OE. We collected data on lipid reserves, parasite loads, and two immune measures (hemocyte concentration and phenoloxidase activity from wild monarchs migrating through north GA (USA to ask whether (1 parasite infection negatively affects lipid reserves, and (2 greater investment in lipid reserves is associated with lower immune measures. Results showed that monarchs sampled later in the fall migration had lower but not significantly different immune measures and significantly higher lipid reserves than those sampled earlier. Lipid measures correlated negatively but only nearly significantly with one measure of immune defense (phenoloxidase activity in both healthy and infected monarchs, but did not depend on monarch infection status or parasite load. These results provide weak support for a trade-off between energy reserves and immune defense in migrants, and suggest that previously-demonstrated costs of OE infection for monarch migration are not caused by depleted lipid reserves [Current Zoology 59 (3: 393–402, 2013].

West Nile virus infection of birds, Mexico.

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.

1992-01-01

Radon-in-soil surveys in Mexico have been carried out since 1974 both for uranium prospecting and to correlate mean values of the gas emanation with local telluric behaviour. The mapping covers the northern uranium mining region, the Mexican Neovolcanic Belt, the coastal areas adjacent to the zone of subduction of the Cocos Plate under the North American Plate, some of the active volcanoes of Southern Mexico and several sedimentary valleys in Central Mexico. Recording of 222 Rn alpha decay is systematically performed with LR115 track detectors. Using mean values averaged over different observation periods at fixed monitoring stations, a radon-in-soil map covering one third of the territory of Mexico is presented. The lowest mean values occur in areas associated with active volcanoes. The highest levels are found in uranium ore zones. Intermediate values are obtained in regions with enhanced hydrothermal activity and stations associated with intrusive rocks. (author)

The law on the streets: Evaluating the impact of Mexico's drug decriminalization reform on drug possession arrests in Tijuana, Mexico.

Arredondo, J; Gaines, T; Manian, S; Vilalta, C; Bañuelos, A; Strathdee, S A; Beletsky, L

2018-04-01

In 2009, Mexican Federal Government enacted "narcomenudeo" reforms decriminalizing possession of small amounts of drugs, delegating prosecution of retail drug sales to the state courts, and mandating treatment diversion for habitual drug users. There has been insufficient effort to formally assess the decriminalization policy's population-level impact, despite mounting interest in analagous reforms across the globe. Using a dataset of municipal police incident reports, we examined patterns of drug possession, and violent and non-violent crime arrests between January 2009 and December 2014. A hierarchical panel data analysis with random effects was conducted to assess the impact of narcomenudeo's drug decriminalization provision. The reforms had no significant impact on the number of drug possession or violent crime arrests, after controlling for other variables (e.g. time trends, electoral cycles, and precinct-level socioeconomic factors). Time periods directly preceding local elections were observed to be statistically associated with elevated arrest volume. Analysis of police statistics parallel prior findings that Mexico's reform decriminalizing small amounts of drugs does not appear to have significantly shifted drug law enforcement in Tijuana. More research is required to fully understand the policy transformation process for drug decriminalization and other structural interventions in Mexico and similar regional and international efforts. Observed relationship between policing and political cycles echo associations in other settings whereby law-and-order activities increase during mayoral electoral campaigns.

We examined the effect of tobacco control policies in Mexico on smoking prevalence and smoking-related deaths using the Mexico SimSmoke model. The model is based on the previously developed SimSmoke simulation model of tobacco control policy, and uses population size, smoking rates and tobacco control policy data for Mexico. It assesses, individually, and in combination, the effect of six tobacco control policies on smoking prevalence and smoking-related deaths. Policies included: cigarette excise taxes, smoke-free laws, anti-smoking public education campaigns, marketing restrictions, access to tobacco cessation treatments and enforcement against tobacco sales youth. The model estimates that, if Mexico were to adopt strong tobacco control policies compared to current policy levels, smoking prevalence could be reduced by 30% in the next decade and by 50% by 2053; an additional 470,000 smoking-related premature deaths could be averted over the next 40 years. The greatest impact on smoking and smoking-related deaths would be achieved by raising excise taxes on cigarettes from 55% to at least 70% of the retail price, followed by strong youth access enforcement and access to cessation treatments. Implementing tobacco control policies in Mexico could reduce smoking prevalence by 50%, and prevent 470,000 smoking-related deaths by 2053.

Full Text Available OBJECTIVES: To examine physical and mental health domains of health-related quality of life (HRQL in a binational adult population with type 2 diabetes at the Texas-Mexico border, and to explore individual and social correlates to physical and mental health status. METHODS: Adults 18 years and older with type 2 diabetes residing in the South Texas Lower Rio Grande Valley and in Reynosa, Tamaulipas, Mexico, were recruited using a convenience sampling technique and interviewed face-to-face with a structured survey. HRQL was measured using physical and mental health summary components of the Medical Outcomes Study Short Form. HRQL correlates included demographic characteristics, health factors, access to healthcare, and family support. Samples characteristics were compared using the Student’s t-test or Mann-Whitney U test. Associations between dependent and independent variables were examined using unadjusted and adjusted (multiple variable logistic regression models. RESULTS: There were no significant differences between Valley and Reynosa respondents in physical or mental health status scores. Valley participants with lower socioeconomic status and those perceiving their supportive relative’s level of diabetes-related knowledge as "low" were more likely to report worse physical health than those lacking those characteristics. In the Reynosa group, lower physical health status was associated with duration of diabetes and insulin use. Both sample populations with clinical depressive symptoms were more likely to have worse physical and mental health than those without such symptoms. CONCLUSIONS: HRQL is an important outcome in monitoring health status. Understanding the levels and influences of HRQL in U.S.-Mexico border residents with diabetes may help improve diabetes management programs.OBJETIVOS: Analizar los dominios de salud física y mental de la calidad de vida relacionada con la salud (CVRS en una población binacional de adultos con

The Department of Energy's Strategic Petroleum Reserve Program began discharging brine into the Gulf of Mexico from its West Hackberry site near Cameron, Louisiana in May 1981. The brine originates from underground salt domes being leached with water from the Intracoastal Waterway, making available vast underground storage caverns for crude oil. The effects of brine discharge on aquatic organisms are presented in this volume. The topics covered are: benthos; nekton; phytoplankton; zooplankton; and data management.

The regulation antecedents in nuclear question in Mexico are placed in 1950, with the promulgation of {sup L}aw that declares national mining reserves the uranium deposits, thorium and the other substances of which obtains fissionable isotopes that can produce nuclear energy{sup ,} instrument that stipulated the control of uranium, thorium, as to its it indicated it name, and other fissionable substances, on the part of the state, although they were without a doubt the respective institutions, the National Commission of Nuclear Energy in 1955, and the one of the National Commission of Nuclear Safety and Safeguards (CNSNS) in 1979, those that allowed the development of a prescribed frame in the nuclear and radiological areas. One characteristic of the regulation in radiological protection is the variety in the authorities type that have incidence in the regulation, as a result of the different approaches with which it can be approached. For example, in Mexico normative instruments with content in radiological protection exist and are watched over the Health Secretary, who is oriented to the protection of the patient, their relatives and the medical body; Work and Social Welfare Secretary, with a labor approach; Communications and Transport Secretary, which regulates the transport of nuclear and radioactive materials; Finance and Public Credit Secretary, who regulates the import and export of radioactive materials; Environment and Natural Resources Secretary, which regulates the environment protection; Energy Secretary who has responsibilities inside of the {sup p}rescribed law of article 27 constitutional in nuclear matter{sup ;} and within the energy sector, the CNSNS that expedite and watch the fulfillment of normative in radiological protection and nuclear safety. In order to resist effects of on regulation; frequently inter institutional agreements are carried out in which the areas of monitoring are agreed by each authority. The regulation in radiological

The first week of September 2013, the National Epidemiological Surveillance System identified two cases of cholera in Mexico City. The cultures of both samples were confirmed as Vibrio cholerae serogroup O1, serotype Ogawa, biotype El Tor. Initial analyses by PFGE and by PCR-amplification of the virulence genes, suggested that both strains were similar, but different from those previously reported in Mexico. The following week, four more cases were identified in a community in the state of Hidalgo, located 121 km northeast of Mexico City. Thereafter a cholera outbreak started in the region of La Huasteca. Genomic analyses of the four strains obtained in this study confirmed the presence of Pathogenicity Islands VPI-1 and -2, VSP-1 and -2, and of the integrative element SXT. The genomic structure of the 4 isolates was similar to that of V. cholerae strain 2010 EL-1786, identified during the epidemic in Haiti in 2010. Copyright © 2016 Institut Pasteur.

Excise taxes are the primary public health strategy used to increase the price of cigarettes in the United States. Rather than quitting or reducing consumption of cigarettes, some price-sensitive smokers may avoid state and local excise taxes by purchasing cigarettes from Indian reservations. The objectives of this study were to (1) provide the most recent state-specific prevalence of purchases made on Indian reservations by non–American Indians/Alaska Natives (non-AI/ANs) and (2) assess the impact of these purchases on state tax revenues. We used data from a large national and state-representative survey, the 2010-2011 Tobacco Use Supplement to the Current Population Survey, which collects self-reported measures on cigarette use and purchases. Nationwide, 3.8% of non-AI/AN smokers reported purchasing cigarettes from Indian reservations. However, in Arizona, Nevada, New Mexico, New York, Oklahoma, and Washington State, about 15% to 30% of smokers reported making such purchases, resulting in annual tax revenue losses ranging from $3.5 million (Washington State) to $292 million (New York) during 2010-2011. Strategies to reduce the sale of non- or lower-taxed cigarettes to non-AI/ANs on Indian reservations have the potential to decrease smoking prevalence and recoup lost revenue from purchases made on reservations.

Dengue is an acute febrile illness caused by any of four dengue virus types (DENV-1-4). DENVs are transmitted by mosquitos of the genus Aedes (1) and are endemic throughout the tropics (2). In 2010, an estimated 390 million DENV infections occurred worldwide (2). During 2007-2013, a total of three to 10 dengue cases were reported annually in Arizona and all were travel-associated. During September-December 2014, coincident with a dengue outbreak in Sonora, Mexico, 93 travel-associated dengue cases were reported in Arizona residents; 70 (75%) cases were among residents of Yuma County, which borders San Luis Río Colorado, Sonora, Mexico. San Luis Río Colorado reported its first case of locally acquired dengue in September 2014. To investigate the temporal relationship of the dengue outbreaks in Yuma County and San Luis Río Colorado and compare patient characteristics and signs and symptoms, passive surveillance data from both locations were analyzed. In addition, household-based cluster investigations were conducted near the residences of reported dengue cases in Yuma County to identify unreported cases and assess risk for local transmission. Surveillance data identified 52 locally acquired cases (21% hospitalized) in San Luis Río Colorado and 70 travel-associated cases (66% hospitalized) in Yuma County with illness onset during September-December 2014. Among 194 persons who participated in the cluster investigations in Yuma County, 152 (78%) traveled to Mexico at least monthly during the preceding 3 months. Four (2%) of 161 Yuma County residents who provided serum samples for diagnostic testing during cluster investigations had detectable DENV immunoglobulin M (IgM); one reported a recent febrile illness, and all four had traveled to Mexico during the preceding 3 months. Entomologic assessments among 105 households revealed 24 water containers per 100 houses colonized by Ae. aegypti. Frequent travel to Mexico and Ae. aegypti colonization indicate risk for local

Migrant deaths at the Arizona-Mexico border: Spatial trends of a mass disaster.

Giordano, Alberto; Spradley, M Katherine

2017-11-01

Geographic Information Science (GIScience) technology has been used to document, investigate, and predict patterns that may be of utility in both forensic academic research and applied practice. In examining spatial and temporal trends of the mass disaster that is occurring along the U.S.-Mexico border, other researchers have highlighted predictive patterns for search and recovery efforts as well as water station placement. The purpose of this paper is to use previously collected spatial data of migrant deaths from Arizona to address issues of data uncertainty and data accuracy that affect our understanding of this phenomenon, including local and federal policies that impact the U.S.-Mexico border. The main objective of our study was to explore how the locations of migrant deaths have varied over time. Our results confirm patterns such as a lack of relationship between Border Patrol apprehensions and migrant deaths, as well as highlight new patterns such as the increased positional accuracy of migrant deaths recorded closer to the border. This paper highlights the importance of using positionally accurate data to detect spatio-temporal trends in forensic investigations of mass disasters: without qualitative and quantitative information concerning the accuracy of the data collected, the reliability of the results obtained remains questionable. We conclude by providing a set of guidelines for standardizing the collection and documentation of migrant remains at the U.S.-Mexico border. Copyright © 2017 Elsevier B.V. All rights reserved.

In this work the analysis of strengths, opportunities, vulnerabilities and threats (SOVT) of the nuclear industry in Mexico is presented. This industry presents among its strengths that Mexico is a highly electrified country and has a good established normative mark of nuclear security. Although the Secretaria de Energia in Mexico, with base to the exposed in the Programa Sectorial de Energia 2007-2012, is analyzing the convenience of the generation starting from this source, considering the strong technological dependence of the exterior and the limited federal budget dedicated to this field. As a result of the analysis of the SOVT matrix, were found a great number of strengths that threats, although the vulnerabilities list is major to the strengths, the opportunities list is the bigger. Therefore, the nuclear industry can be a sustainable industry, taking the necessary decisions and taking advantage of the detected opportunities. (Author)

Organochlorine pesticides in soils of Mexico and the potential for soil-air exchange.

Science.gov (United States)

Wong, Fiona; Alegria, Henry A; Bidleman, Terry F

2010-03-01

The spatial distribution of organochlorine pesticides (OCs) in soils and their potential for soil-air exchange was examined. The most prominent OCs were the DDTs (Geometric Mean, GM=1.6 ng g(-1)), endosulfans (0.16 ng g(-1)), and toxaphenes (0.64 ng g(-1)). DDTs in soils of southern Mexico showed fresher signatures with higher FDDTe=p,p'-DDT/(p,p'-DDT+p,p'-DDE) and more racemic o,p'-DDT, while the signatures in the central and northern part of Mexico were more indicative of aged residues. Soil-air fugacity fractions showed that some soils are net recipients of DDTs from the atmosphere, while other soils are net sources. Toxaphene profiles in soils and air showed depletion of Parlar 39 and 42 which suggests that soil is the source to the atmosphere. Endosulfan was undergoing net deposition at most sites as it is a currently used pesticide. Other OCs showed wide variability in fugacity, suggesting a mix of net deposition and volatilization.

Child abuse (CA) was observed in Mexico since the early 60's through isolated publications from clinical cases and where manifestations of physical injury or sexual abuse predominated. Since the 90's, the Clinic for Integral Care of the Abused Child was established at the National Institute of Pediatrics (CAINM-INP, for its Spanish acronym), which actions were addressed to the care, teaching and research on this topic. This approach was replicated in two hospital centers in the country: the Clinic for Integral Care of the Abused Children at Children's Specialty Care Hospital of Chihuahua and the Pediatric Service of the General Hospital of Mexicali. The main objective of this work was to present to the medical community, paramedics, and other professionals who interact with the pediatric population and society, the efforts that have been made in Mexico to address this legal, medical, and social pathology in a logical manner, and always aimed at protecting victims and their families.

Seasonal variation in penicillin use in Mexico and Brazil: analysis of the impact of over-the-counter restrictions.

Science.gov (United States)

Santa-Ana-Tellez, Yared; Mantel-Teeuwisse, Aukje K; Leufkens, Hubert G M; Wirtz, Veronika J

2015-01-01

During 2010, Mexico and Brazil implemented policies to enforce existing laws of restricting over-the-counter sales of antibiotics. We determined if the enforcement led to more appropriate antibiotic use by measuring changes in seasonal variation of penicillin use. We used retail quarterly sales data in defined daily doses per 1,000 inhabitant-days (DDD/TID) from IMS Health from the private sector in Mexico and Brazil from the first quarter of 2007 to the first quarter of 2013. This database contains information on volume of antibiotics sold in retail pharmacies using information from wholesalers. We used interrupted time-series models controlling for external factors with the use of antihypertensives with interaction terms to assess changes in trend, level, and variation in use between quarters for total penicillin use and by active substance. The most used penicillin was amoxicillin, followed by amoxicillin-clavulanic acid and ampicillin (minimal use in Brazil). Before the restrictions, the seasonal variation in penicillin use was 1.1 DDD/TID in Mexico and 0.8 DDD/TID in Brazil. In Mexico, we estimated a significant decrease in the seasonal variation of 0.4 DDD/TID after the restriction, mainly due to changes in seasonal variation of amoxicillin and ampicillin. In Brazil, the seasonal variation did not change significantly, overall and in the breakdown by individual active substances. For Mexico, inappropriate penicillin use may have diminished after the restrictions were enforced. For Brazil, increasing use and no change in seasonal variation suggest that further efforts are needed to reduce inappropriate penicillin use. Copyright © 2015, American Society for Microbiology.

Orcajo-Castelán, Rodrigo; Sidonio-Aguayo, Beatriz; Alcacio-Mendoza, Jorge Augusto; López-Díaz, Giovana Lucía

In recent years a number of child development screening tools have been developed in Mexico; however, their properties have not been compared. The objective of this review was to compare the report quality and risk bias of the screening tools developed and validated in Mexico in their published versions. A search was conducted in databases, gray literature and cross references. The resultant tests were compared and analyzed using STARD, QUADAS and QUADAS-2 criteria. "Valoración Neuroconductual del Desarrollo del Lactante" (VANEDELA), "Evaluación del Desarrollo Infantil or EDI" (CDE in English), "Prueba de Tamiz del Neurodesarrollo infantil" (PTNI), "Cartillas de Vigilancia para identificar alteraciones en el Desarrollo del Lactante" (CVDL) and "Indicadores de riesgo del Perfil de Conductas de Desarrollo" (INDIPCD-R) were included for the comparison. No test fulfilled all STARD items. The most complete in their methodological description were VANEDELA and EDI. The areas lacking more data on the reports were recruiting and patient selection (VANEDELA, PTNI, CVDL, INDIPCD-R). In QUADAS evaluation, all had some risk bias, but some serious concerns of risk bias were raised by patient sampling and by the choice of gold standard in two tests (PTNI, INDIPCD-R). Child development screening tests created and validated in Mexico have variable report quality and risk bias. The test with the best validation report quality is VANEDELA and the one with the lowest risk of bias is EDI. Copyright © 2015 Hospital Infantil de México Federico Gómez.

Return Migration to Mexico: Does Health Matter?

Science.gov (United States)

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.

To investigate whether increased knowledge and use of public health measures promoted for cholera prevention is reflected in lower prevalence of parasitic infection in households in a community in the state of Tamaulipas, Mexico, that is close to the border with the United States of America. Between 1994 and 1997, fecal samples from 438 children were collected through convenience sampling and then examined for helminth eggs/larvae and protozoan cysts as biologic indicators of household compliance with recommended cholera prevention measures. The suggested measures were to wash hands before meals and after defecation, to drink purified water, to wash fruits and vegetables, and to eat well-cooked food. In addition, information on the knowledge of and the use of cholera preventive measures was collected by interviews with adult informants in 252 households (186 of those households also provided a fecal sample for analysis). Parasitic infections occurred in 131 of the 438 children (30%), who resided in 79 of the 186 households (42%) that provided fecal samples. Giardia lamblia accounted for 12.5% of all infections. Infections with Hymenolepis nana, Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis, Ancylostoma/Necator, Strongyloides stercoralis, Entamoeba coli, Entamoeba hartmanni, Entamoeba histolytica, Endolimax nana, and Iodamoeba bütschlii were also noted. Infected children were older and more often had an infected sibling. Households with three or more children were also more likely to have an infected child. The primary caregivers in the households where at least one child had a parasitic infection were distinguished by their inability to list at least three cholera prevention measures from memory. The 42% household prevalence of parasitic infection was relatively high and indicates that some residents of this community may not have fully embraced the public health education efforts promoted for prevention of cholera.

Brucellosis is one of the most frequent zoonosis in most parts of the world. 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.

Environmental flow calculation for the maintenance of the water reserve of the Piaxtla River, Sinaloa, Mexico

Directory of Open Access Journals (Sweden)

Guadalupe de la Lanza Espino

2014-03-01

Full Text Available The calculation of river flows necessary to maintain the environmental services of the diverse river basins in Mexico has been an element to be considered in complying with the Mexican Norm and in allowing an adequate administration of water resources. Several methods have been proposed for this calculation, among which a very simple one is a hydrological method that requires a data base on runoff to determine the volume of water that ecosystem functions need. Hydrological methodology proposed by the NMX cited above, provides guidelines for establishing a regime as a percentage of average annual runoff and it is assumed maintain biological attributes at certain levels of conservation. It also analyzes the regime of seasonal normal flow for wet hydrological conditions, socks, dry and very dry, and the system of avenues (considered as the sudden increase in the volume and speed of the current in a river due to runoff resulting from rain cyclical or extraordinary, it is also known as flooding, considering at least three categories of avenues (intra-annual, annual and interannual low magnitude of average size with corresponding attributes of magnitude, duration, frequency, time of occurrence and rate exchange. For greater certainty calculation it will always be necessary to have records in the three levels of a basin. This level of analysis is to determine the final volume of ecological flow, considering the benchmark to achieve the previously defined environmental objective. For ecological calculation referred by the NMX, some fundamental aspects were considered, such as: ecology importance (which ranks among very high, high, medium and low based on the concepts of the rule itself ; use pressures (determined as the ratio percentage of the volume allocated over the concession between the annual average availability basin or aquifer, determined as high ≥ 80%, ≥ 40% high, medium and low ≥ 11% ≤ 10% ; the environmental objective (ecological

Social manifestations of abortion stigma depend upon cultural, legal, and religious context. Abortion stigma in Mexico is under-researched. This study explored the sources, experiences, and consequences of stigma from the perspectives of women who had had an abortion, male partners, and members of the general population in different regional and legal contexts. We explored abortion stigma in Mexico City where abortion is legal in the first trimester and five states-Chihuahua, Chiapas, Jalisco, Oaxaca, and Yucatán-where abortion remains restricted. In each state, we conducted three focus groups-men ages 24-40 years (n = 36), women 25-40 years (n = 37), and young women ages 18-24 years (n = 27)-and four in-depth face-to-face interviews in total; two with women (n = 12) and two with the male partners of women who had had an abortion (n = 12). For 4 of the 12 women, this was their second abortion. This exploratory study suggests that abortion stigma was influenced by norms that placed a high value on motherhood and a conservative Catholic discourse. Some participants in this study described abortion as an "indelible mark" on a woman's identity and "divine punishment" as a consequence. Perspectives encountered in Mexico City often differed from the conservative postures in the states.

A perspective of food safety laws in Mexico.

Science.gov (United States)

Leon, Marco A; Paz, Esmeralda

2014-08-01

Mexico, with a population of 112 million, is one of the most interesting countries in the world with regard to food, hunger, domestic food consumption, tourism and international trade, and it deserves an in-depth study to explain the status of its food safety laws. Mexico has a strong and stable emerging economy and is the second country worldwide with regard to the number of free-trade agreements. Nevertheless, more than half the population lives in poverty. However, Mexico is a huge market for food consumption because, in addition to its own population, it receives 20 million international tourists per year. So, multi-national food companies have representatives and facilities throughout the country. This scenario may explain the evolution of food safety laws in Mexico, as well as the challenges that must be faced in order to achieve food safety. © 2013 Society of Chemical Industry.

In this report present a general overview of energy trends and objectives of policy for Mexico, in the context of sustainable development. The work is divided in two main parts: the first one presents trends in energy use and potential, energy sector reform, social and economics indicators and revision of efficiency and renewable energy. The second part discusses options and instruments of energy politics for the country in regard of the sustainable development. The energy is central to concerns of sustainable development, affecting economic; the local and global environment, and social problems as poverty, population, health and education. Mexico should promote political energy that permit the fulfillment the energy requirements while developing strategies that help to alleviate the social problems and productivity, based on lesser environmental impacts. [Spanish] Este reporte presenta una vision sobre las tendencias energeticas de Mexico y plantea prioridades y objetivos de politica para el pais, en el contexto de desarrollo sustentable. El trabajo muestra dos partes principales: la primera seccion presenta tendencias en el uso de energia, potenciales energeticos e indicadores economicos y sociales, ademas de una revision de eficiencias y politicas de energias renovables. La segunda parte discute opciones, instrumentos y restricciones en el contexto del desarrollo energetico sustentable en el pais. La energia es un elemento central en el desarrollo ya que esta relacionado con la economia, el ambiente local y global y aspectos sociales como pobreza, poblacion, salud y educacion. Esto obliga en Mexico a promover politicas que permitan la cobertura de los requerimientos energeticos, las cuales deben desarrollarse de manera conjunta con estrategias, para ayudar a disminuir los problemas, productivos y sociales con menores impactos ambientales.

Molecular Relationship between Strains of M. bovis from Mexico and Those from Countries with Free Trade of Cattle with Mexico.

Directory of Open Access Journals (Sweden)

Feliciano Milian-Suazo

Full Text Available The purpose of this study was to identify relationships between spoligotypes of M. bovis from cattle in Mexico and those reported in countries with free trade of cattle with Mexico: Australia, Canada, New Zealand and the United States of America. Mexican spoligotypes were obtained from isolates collected from cattle in different parts of the country. Spoligotypes from Canada and New Zealand were obtained from different reports in the literature. Those from the United States were obtained from the database of the National Veterinary Services Laboratory in APHIS-USDA. In order to perform the analysis in a single data set, spoligotypes were all converted to binary data and classified according to www.mbovis.org or www.pasteur-guadeloupe.fr:8081. Epidemiologic information included country and species infected. From 3,198 isolates, 174 different spoligotypes were obtained, 95 were orphans. Ninety one percent of the isolates came from the Unites States (n = 1,609 and Mexico (n = 1,323. Spoligotype SB0265 is shared between Canada and the United States in cattle and wildlife. Six spoligotypes, SB0673, SB0121, SB0145, SB0971, SB0140 and SB1165, were frequent in cattle and wildlife in the United States and cattle in Mexico, suggesting wide exchange of strains. Spoligotype SB0669 was found only in Mexico. Spoligotype SB0140 was the most common in Australia and the sixth in the United States and Mexico. In a phylogenetic analysis, spoligotype SB0140 appears as the oldest spoligotype in the data set, suggesting this as the ancestral spoligotype for all spoligotypes in the five countries. Some spoligotypes are shared by animals and humans, corroborating the zoonotic importance of M. bovis.

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.

Pupal deposition and ecology of bat flies (Diptera: Streblidae): Trichobius sp. (caecus group) in a Mexican cave habitat.

Science.gov (United States)

Dittmar, Katharina; Dick, Carl W; Patterson, Bruce D; Whiting, Michael F; Gruwell, Matthew E

2009-04-01

We studied the deposition of pupae of the winged bat fly Trichobius sp. (caecus group; Diptera), an ectoparasite of Natalus stramineus (Chiroptera, Natalidae), in a natural cave in Tamaulipas, Mexico. For the first time, we show a strong spatial segregation of populations of a streblid bat fly at different stages of development. Using molecular techniques we were able to match developmental stages to adults. Only 5 pupae were present in the main bat roosts. The overwhelming majority occurred exclusively in the bat flyway passages at a considerable distance from roosting bats. Pupal density corresponded positively with the average flight height of bats in the cave passage. Taken together, observations suggest that these ectoparasites must actively seek out their hosts by moving onto passing or roosting bats. The scarceness of pupae in the main roost may be dictated by environmental constraints for their development. The estimated population of viable pupae far exceeds the population of imagoes on the bats, and predation on adults by spiders is common.

Discovery of a second population of white-collared seedeaters, Sporophila torqueola (Passeriformes: emberizidae) along the Rio Grande of Texas

Woodin, Marc C.; Skoruppa, Mary K.; Blacklock, Gene W.; Hickman, Graham C.

1999-01-01

The range of the white-collared seedeater (Sporophila torqueola), a tropical grassland species, extends from Central America northward along both coasts of Mexico (Eitniear, 1997), including Tamaulipas and Nuevo Leon (Howell and Webb, 1995). White-collared seedeaters historically occurred commonly in extreme southern Texas (Oberholser, 1974; Rappole and Blacklock, 1994). However, since about 1950, white-collared seedeaters have undergone a precipitous decline in south Texas. Studies during 1994-1996 identified only seven to nine breeding pairs in the only population known to occur in Texas, located ca. 55 km downriver of Laredo, Texas, in Zapata Co. (Eitniear, 1997). Outside of the historical range, very few records are documented. Oberholser (1974) reported that three white-collared seed- eater specimens were collected in 1948 in Webb Co., northwest of Laredo, and Arnold (1980) also collected a white-collared seedeater in Webb Co. Vagrants also have been sighted as far afield as Corpus Christi (Blacklock, 1964), ca. 200 km north of the Rio Grande (Fig. 1).

This study examines urban pollution within Derechos Humanos, a colonia popular in Matamoros, Tamaulipas, Mexico. General water quality indicators (coliform bacteria, total dissolved solids, ecologically relevant cations and anions), heavy metals (copper, lead, nickel, zinc, iron and cadmium), and volatile organic compounds (benzene, toluene, ethylbenzene, styrene, and dichlorobenzene and xylene isomers) were quantified within a wastewater canal running adjacent to the community. Water samples were collected at multiple sites along the banks of the canal and evidence of anthropogenic emissions existed at each sampling location. Sample site 2, approximately 10 m upstream of the colonia, contained both the widest range of hazardous pollutants and the greatest number exceeding US Environmental Protection Agency surface water standards. At each sampling location, high concentrations of total coliform (> 10(4) colonies/100 mL sample), lead (ranging from 0.05 to 0.40 mg/L), nickel (levels from 0.21 to 1.45 mg/L), and benzene (up to 9.80 mg/L) were noted.

[Origins of institutional Pediatrics: Maternity and Childhood Hospital of Mexico City in the nineteenth century].

Science.gov (United States)

Baeza Bacab, Manuel Antonio

In June of 1866, the empress Carlota founded the Maternity House in the Department of Secret Births at the Hospice of the Poor. Upon the reinstatement of a republican government, Dr. Ramon Pacheco was appointed director of the Maternity House. Shortly after, in February of 1868, Dr. Luis Fernandez Gallardo established a pavilion for sick children in the Hospital of San Andres. After realizing this pavilion didn't have the adequate conditions to operate properly, and in the need of a children's hospital in Mexico City, Dr. Pacheco merged both institutions in April 2, 1869 -with the help of Ms. Luciana Arrazola- and founded the Maternity and Childhood Hospital, the first institution for the care of ill children in the independent Mexico. Ever since it was founded, Dr. Eduardo Liceaga was in charge of the children's health. Later, with the help of the presidents Juarez, Lerdo de Tejada and Díaz, he was able to consolidate the hospital in academic and health services aspects. This noble institution closed its doors on February 5, 1905, upon its incorporation to the General Hospital of Mexico, after 36 years of working for the welfare of Mexican children.

Designing Distributed Generation in Mexico

Energy Technology Data Exchange (ETDEWEB)

Linvill, Carl [Regulatory Assistance Project, Montepelier, VT (United States); Brutkoski, Donna [Regulatory Assistance Project, Montepelier, VT (United States)

2017-05-15

Mexico's energy reform will have far-reaching effects on how people produce and consume electricity in the country. Market liberalization will open the door to an increasing number of options for Mexican residential, commercial, and industrial consumers, and distributed generation (DG), which for Mexico includes generators of less than 500 kilowatts (kW) of capacity connected to the distribution network. Distributed generation is an option for consumers who want to produce their own electricity and provide electricity services to others. This report seeks to provide guidance to Mexican officials on designing DG economic and regulatory policies.

Catch-up Growth Followed by Stagnation: Mexico, 1950-2010

OpenAIRE

Timothy J. Kehoe; Felipe Meza

2011-01-01

In 1950 Mexico entered an economic takeoff and grew rapidly for more than 30 years. Growth stopped during the crises of 1982-1995, despite major reforms, including liberalization of foreign trade and investment. Since then growth has been modest. We analyze the economic history of Mexico 1877-2010. We conclude that the growth 1950-1981 was driven by urbanization, industrialization, and education and that Mexico would have grown even more rapidly if trade and investment had been liberalized so...

Renewable energy for productive uses in Mexico

Energy Technology Data Exchange (ETDEWEB)

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.

Abortion Legalization and Childbearing in Mexico.

Science.gov (United States)

Gutiérrez Vázquez, Edith Y; Parrado, Emilio A

2016-06-01

In 2007 abortion was legalized in the Federal District of Mexico, making it the largest jurisdiction in Latin America, outside of Cuba, to allow women to have abortions on request during the first trimester of pregnancy. While the implications of the law for women's health and maternal mortality have been investigated, its potential association with fertility behavior has yet to be assessed. We examine metropolitan-area differences in overall and parity-specific childbearing, as well as the age pattern of childbearing between 2000 and 2010 to identify the contribution of abortion legalization to fertility in Mexico. Our statistical specification applies difference-in-difference regression methods that control for concomitant changes in other socioeconomic predictors of fertility to assess the differential influence of the law across age groups. In addition, we account for prior fertility levels and change to better separate the effect of the law from preceding trends. Overall, the evidence suggests a systematic association between abortion legalization and fertility. The law appears to have contributed to lower fertility in Mexico City compared to other metropolitan areas and prior trends. The influence is mostly visible among women aged 20-34 in connection with the transition to first and second child, with limited impact on teenage fertility. There is some evidence that its effect might be diffusing to the Greater Mexico City Metropolitan area. © 2016 The Population Council, Inc.

New Mexico waste plant sits idle amid controversy

International Nuclear Information System (INIS)

Lovejoy, L.A. Jr.

1994-01-01

The Department of Energy (DOE) hopes to permanently dispose of radioactive waste from its weapons program at a Waste Isolation Pilot Plant about 26 miles from Carlsbad, New Mexico. The plant has been plagued by problems, according to Lindsay A. Lovejoy, Jr., an assistant attorney general of New Mexico. Among them are cracks in the walls of some of the underground rooms slated for storage of radioactive waste. Meanwhile, above-ground problems involve DOE's struggle toward regulatory compliance. The Environmental Protection Agency (EPA), under the Resource Conservation Recovery Act, has assumed a regulatory role over DOE's radioactive waste-disposal efforts, which is a new role for the agency. Lovejoy proposes that EPA, in its regulation of the New Mexico plant, develop compliance criteria and involve DOE and the public in ongoing open-quotes dialogue aimed at ferreting out any and all problems before a single scrap of radioactive waste is deposited into the earth beneath new Mexico.close quotes

To estimate the magnitude of diabetes in Mexico, as well as discuss alternative policies to face it appropriately. Descriptive analysis of the National Health and Nutrition Survey 2012, using reported information on previous diagnosis of diabetes from adults and adolescents. From all adults 20 years and older in Mexico, 9.17% has been diagnosed with diabetes, presenting an important geographical heterogeneity, ranging from 5.6% in the southern state of Chiapas, to 12.3% in Mexico City. Of all people with diabetes, 46.95% also have been diagnosed with hypertension, 4.47% has had a stroke, and 54.46%, reported family background of diabetes. Regarding adolescents, 0.68% has been already diagnosed with diabetes. The burden of diabetes in Mexico and the fact that is a preventable condition, calls to strengthen the health sector strategies to face it. The negative effect it has on the quality of life makes diabetes a priority for the health sector.

Quintanilla Martinez, Juan [Programa Universitario de Energia, UNAM (Mexico)

1996-07-01

The projections of demand of energy for Mexico, in the global and regional scope, for period 1992-2020 are presented. The projections are based on the use of a simulation model built in the University Program of Energy of the Universidad Nacional Autonoma de Mexico (UNAM), which allows to project the demand in the short and medium term of the primary and final energy. Projections of the demands of energy or for fuels by sectors and subsectors are obtained in accordance with different scenarios of growth. Particularly the demand of natural gas is analyzed, both, as energy and as raw material for the petrochemical industry, and as fuel oil, under different scenarios of economic growth and policies of environmental character. [Spanish] Se presentan las proyecciones de demanda de energia para Mexico, en el ambito global y regional, para el periodo 1992-2020. Las proyecciones estan basadas en el uso de un modelo de simulacion construido en el Programa Universitario de Energia de la Universidad Nacional Autonoma de Mexico (UNAM), el cual permite proyectar la demanda de energia primaria y final en el corto y mediano plazos. Se obtienen proyecciones de las demandas de energia por sectores y subsectores o por combustibles de acuerdo con diferentes escenarios de crecimiento. En particular se analiza la demanda de gas natural, tanto como energetico como materia prima para la petroquimica, y combustoleo bajo diferentes escenarios de crecimiento economico y politicas de caracter ambiental.

The chewing lice (Insecta: Phthiraptera: Amblycera and Ischnocera) of Mexico have been little studied and many publications include isolated records. This paper summarizes current knowledge of chewing lice recorded from Mexico resulting from an exhaustive search of the literature published from 1866 to 2017. We found 342 louse species associated with 206 bird and 28 mammal species. As a result, we provide a checklist of the chewing lice recorded from Mexico, including a host-parasite list and their geographical distribution within the country.

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

This study explores the impact of diabetes on employment in Mexico using data from the Mexican Family Life Survey (MxFLS) (2005), taking into account the possible endogeneity of diabetes via an instrumental variable estimation strategy. We find that diabetes significantly decreases employment probabilities for men by about 10 percentage points (pdiabetes being endogenous. Further analysis shows that diabetes mainly affects the employment probabilities of men and women above the age of 44 and also has stronger effects on the poor than on the rich, particularly for men. We also find some indication for more adverse effects of diabetes on those in the large informal labour market compared to those in formal employment. Our results highlight--for the first time--the detrimental employment impact of diabetes in a developing country. Copyright © 2015 Elsevier B.V. All rights reserved.

Systemic hypertension (HTN) is a common risk factor for cardiovascular disease. In Mexico, HTN prevalence has increased over time and is currently 31%. Nonetheless, information about the country's HTN incidence and its associated risk factors is scarce. Understanding this condition is a priority for identifying the scope of primary prevention. The main objective of this study is to evaluate the effect of traditional and non-traditional risk factors on the incidence of HTN in a cohort of healthy Mexico City residents under biannual follow-up for 10 years. A prospective longitudinal study is proposed in which clinically healthy residents of Mexico City between 20 and 50 years old will be recruited; the participants will be evaluated every 2 years over a period of 10 years or until they develop HTN. Evaluations regarding sociodemographic, clinical, anthropometric, biochemical, diet, physical activity, stress, sleep quality, alcohol and tobacco consumption factors will be performed. The participants will be recruited from the 16 municipalities of Mexico City through promotional strategies aimed at the community and will be clinically evaluated at a tertiary care institution, Instituto Nacional de Cardiología Ignacio Chávez (National Institute of Cardiology Ignacio Chavez), located in Mexico City, Mexico. Sample size estimated for this study is 3436, and the Cox proportional hazards model will be used to estimate HRs for the association between explanatory variables and HTN using both raw and adjusted data. This study was approved by the Institutional Bioethics Committee of the Instituto Nacional de Cardiología Ignacio Chávez (National Institute of Cardiology Ignacio Chavez) under number 13-802. Findings from this study will be disseminated through scientific papers and research conferences. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Mexico City is one of the most populated cities in the world with almost 22 million inhabitants, located at an altitude of 2200 m. The old city was founded on an ancient lake and the zone is known by its high seismicity; indoor radon determination is an important public health issue. In this paper the data of indoor radon levels in Mexico City, measured independently by two research groups, both using Nuclear Track Detector systems but different methodologies, are correlated. The measurements were done during similar exposure periods of time, at family houses from the political administrative regions of the city. The results indicate a correlation coefficient between the two sets of data of R=0.886. Most of the differences between the two sets of data are inherent to houses having extreme (very high or very low indoor radon) included in the statistics of each group. The total average indoor radon found in Mexico City considering the two methods was 87Bqm{sup -3}.

Elimination of Onchocerciasis from Mexico.

Directory of Open Access Journals (Sweden)

Mario A Rodríguez-Pérez

Full Text Available 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.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.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.

The articulation of Mexico into the dynamics of competition of the North American natural gas market

International Nuclear Information System (INIS)

Elizalde Baltierra, A.

2002-07-01

Deregulation is at the origin of the new dynamics of competition in the natural gas industry. The United States and Canada were the pioneer countries to suffer these changes. In fact, their natural gas markets today function in a very similar way: i) the private sector takes a place as large as possible, and ii)competition is developed within the three segments of the gas value, especially at the upstream level (emergence of hubs, spot and financial markets,...). In Mexico, its downstream gas activities (transportation, storage and distribution) were liberalized in 1995 in order to attract private investments and to develop the gas sector that has historically been operated under State control. Gas upstream operations remain reserved by the Constitution to the national oil company Petroleos Mexicanos (PEMEX). This thesis develops an evaluation framework of the articulation of Mexico into the dynamics of competition of the North American natural gas market, based on the structure-conduct-performance paradigm. In the first part, all North American's natural gas industries base conditions are analyzed. We examine in the second part, the deregulation and articulation of the dynamics of competition of the American and Canadian gas industries. Finally, in the third part we analyze the main elements of the articulation of Mexico into the dynamics of competition of United States and Canada's gas industries. Furthermore, we evaluate the impact of three of these elements (the economic growth, the electric power generation sector and eventually opening to private investments of gas upstream activities) on the adjustment of gas supply and demand in Mexico to the year 2020.

Upper Mantle Discontinuities Underneath Central and Southern Mexico

Science.gov (United States)

Perez-Campos, X.; Clayton, R. W.

2011-12-01

Central and southern Mexico are affected by the subduction of Cocos plate beneath North American plate. The MesoAmerican Subduction Experiment (MASE) and the Veracruz-Oaxaca (VEOX) project have mapped the geometry of the Cocos slab. It is characterized in central Mexico by a shallow horizontal geometry up to ~300 km from the trench, then it dives steeply (70°) into the mantle, to its apparent end at 500 km depth. In contrast, some 400 km to the south, the slab subducts smoothly, with a dip angle of ~26° to a depth of 150 km. We use receiver functions from teleseismic events, recorded at stations from MASE, VEOX, and the Servicio Sismológico Nacional (SSN, Mexican National Seismological Service) to map the upper mantle discontinuities and properties of the transition zone in central and southern Mexico. We also use data from the Mapping the Rivera Subduction Zone (MARS) Experiment to get a complete picture of the subduction regime in central Mexico and compare the mantle transition zone in a slab tear regime. The 410 discontinuity shows significant variation in topography in central Mexico, particularly where the slab is expected to reach such depth. The 660 discontinuity shows a smoother topography, indicating that the slab does not penetrate this far down. The results will be compared with a ridge regime in the Gulf of California.

Establishing a Water Resources Resilience Baseline for Mexico City

Science.gov (United States)

Behzadi, F.; Ray, P. A.

2017-12-01

There is a growing concern for the vulnerability of the Mexico City water system to shocks, and the capacity of the system to accommodate climate and demographic change. This study presents a coarse-resolution, lumped model of the water system of Mexico City as a whole, designed to identify system-wide imbalances, and opportunities for large-scale improvements in city-wide resilience through investments in water imports, exports, and storage. In order to investigate the impact of climate change in Mexico City, the annual and monthly trends of precipitation and temperature at 46 stations near or inside the Mexico City were analyzed. The statistical significance of the trends in rainfall and temperature, both over the entire period of record, and the more recent "climate-change-impacted period" (1970-2015), were determined using the non-parametric Mann-Kendall test. Results show a statistically significant increasing trend in the annual mean precipitation, mean temperature, and annual maximum daily temperature. However, minimum daily temperature does not appear to be increasing, and might be decreasing. Water management in Mexico City faces particular challenges, where the winter dry season is warming more quickly than the wet summer season. A stress test of Mexico City water system is conducted to identify vulnerabilities to changes in exogenous factors (esp., climate, demographics, land use). Following on the stress test, the relative merits of adaptation options that might improve the system's resilience and sustainability will be assessed.

The impact of taxation on tobacco consumption in Mexico.

The price of cigarettes to consumers in Mexico, and Latin America in general, remains low in comparison with other regions of the world. In Mexico, taxes represented 59% of the total price of cigarettes in 2006, compared to 75% or more in many high-income countries. The feasibility of raising taxes on cigarettes in Mexico--to both discourage consumption and increase revenues--is an important policy question. Using household survey data, we undertake a pooled cross-sectional analysis of the demand for cigarettes in Mexico. We use a two-part model to estimate the price elasticity of cigarettes. This model controls for the selection effect that arises from the fact that the impact of price on the decision to smoke or not is estimated using all households in the dataset. The results indicate that price is a significant factor in household decisions concerning smoking and the number of cigarettes smoked. Holding other factors constant, our simulations show that a 10% increase in the cigarette tax in Mexico--calculated as a percentage of the price--yields a 12.4% increase in the price to the consumer, a 6.4% decrease in consumption of cigarettes and a 15.7% increase in the revenue yielded by the tax. In Mexico, there are strong arguments for increasing cigarette taxes. Revenue raised could be used to further prevent tobacco consumption and to finance current funding shortages for the treatment of diseases related to smoking.

Blooms of the toxic marine dinoflagellate Karenia brevis cause massive fish kills and other public health and economic problems in coastal waters throughout the Gulf of Mexico [Steidinger, 2009]. These harmful algal blooms (HABs) are a gulf-wide problem that require a synoptic observing system for better serving decision-making needs. The major nutrient sources that initiate and maintain these HABs and the possible connectivity of blooms in different locations are important questions being addressed through new collaborations between Mexican and U.S. researchers and government institutions. These efforts were originally organized under the U.S./Mexico binational partnership for the HABs Observing System (HABSOS), led by the U.S. Environmental Protection Agency's Gulf of Mexico Program (EPAGMP) and several agencies in Veracruz, Mexico, since 2006. In 2010 these efforts were expanded to include other Mexican states and institutions with the integrated assessment and management of the Gulf of Mexico Large Marine Ecosystem (GoMLME) program sponsored by the Global Environment Facility (GEF), the United Nations Industrial Development Organization (UNIDO), the Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT), and the National Oceanic and Atmospheric Administration (NOAA).

The regulation antecedents in nuclear question in Mexico are placed in 1950, with the promulgation of L aw that declares national mining reserves the uranium deposits, thorium and the other substances of which obtains fissionable isotopes that can produce nuclear energy , instrument that stipulated the control of uranium, thorium, as to its it indicated it name, and other fissionable substances, on the part of the state, although they were without a doubt the respective institutions, the National Commission of Nuclear Energy in 1955, and the one of the National Commission of Nuclear Safety and Safeguards (CNSNS) in 1979, those that allowed the development of a prescribed frame in the nuclear and radiological areas. One characteristic of the regulation in radiological protection is the variety in the authorities type that have incidence in the regulation, as a result of the different approaches with which it can be approached. For example, in Mexico normative instruments with content in radiological protection exist and are watched over the Health Secretary, who is oriented to the protection of the patient, their relatives and the medical body; Work and Social Welfare Secretary, with a labor approach; Communications and Transport Secretary, which regulates the transport of nuclear and radioactive materials; Finance and Public Credit Secretary, who regulates the import and export of radioactive materials; Environment and Natural Resources Secretary, which regulates the environment protection; Energy Secretary who has responsibilities inside of the p rescribed law of article 27 constitutional in nuclear matter ; and within the energy sector, the CNSNS that expedite and watch the fulfillment of normative in radiological protection and nuclear safety. In order to resist effects of on regulation; frequently inter institutional agreements are carried out in which the areas of monitoring are agreed by each authority. The regulation in radiological protection demands the

Rivera-Hernandez, Maricruz; Flores Cerqueda, Sergio; García Ramírez, José Carlos

2017-01-01

Life expectancy is increasing in Mexico, creating new opportunities and challenges in different areas, including gerontology and geriatric education and research. Although in the European Union there are more than 3,000 institutions that focus on aging research, in Latin America there are only 250 programs where theoretical and practical knowledge is taught. In Mexico, the number of institutions that offer gerontology and geriatric education is relatively small. One of the major concerns is that Mexico is not adequately prepared to optimally deal with the aging of its population. Thus, the main challenge that Mexico faces is to train practitioners, researchers, and policy makers to be able to respond to the aging priorities of this country. The goal of this review is to investigate the literature regarding 60 years in the fields of gerontology and geriatrics in Mexico. Even when programs have evolved within the past decades, there are some challenges to gerontological and geriatric education and aging research in Mexico. The implications for Mexico are discussed, as well as opportunities for moving these fields forward.

The economic impact of Sandia National Laboratories on Central New Mexico and the State of New Mexico Fiscal Year 1998

Sandia National Laboratories (SNL) is a Department of Energy federally funded national security laboratory that uses engineering and science to ensure the security of the Nation. SNL provides scientific and engineering solutions to meet national needs in nuclear weapons and related defense systems, energy security, and environmental integrity. SNL works in partnerships with universities and industry to enhance their mission and transfer technology that will address emerging national challenges for both government and industry. For several years, the U.S. Department of Energy (DOE) Albuquerque Operations Office (AL) and New Mexico State University (NMSU) have maintained an inter-industry, input-output (I/O) model with capabilities to assess the impacts of developments initiated outside the economy such as federal DOE monies that flow into the state, on an economy. This model will be used to assess economic, personal income and employment impacts of SNL on Central New Mexico and the State of New Mexico. Caution should be exercised when comparing economic impacts between fiscal years prior to this report. The I/O model was rebased for FY 1998. The fringe benefits coefficients have been updated for the FY 1996 and FY 1997 economic impacts analysis. Prior to FY 1993 two different I/O base models were used to estimate the impacts. New technical information was released by the Bureau of Economic Analysis (BEA), U.S. Department of Commerce in 1991 and in 1994 and was incorporated in FY 1991, FY 1993, and FY 1994 I/O models. Also in 1993, the state and local tax coefficients and expenditure patterns were updated from a 1986 study for the FY 1992 report. Further details about the input-output model can be found in ''The Economic Impact of the Department of Energy on the State of New Mexico--FY 1998'' report by Lansford, et al. (1999). For this report, the reference period is FY 1998 (October 1, 1997, through September 30, 1998) and includes two major

How Mexico can advance its petroleum technology without political risk

International Nuclear Information System (INIS)

Baker, G.

1992-01-01

This paper reports that Mexico's National Science Council (NSC) has made a strong appeal to strengthen Mexico's efforts in science. The energy sector is given special treatment, and NSC urges the federal administration to take a sharper look at the medium and long term implications of its modernization plans. The council urges greater efforts at energy conservation and encourages Mexico's State Petroleum Institute (IMP) to develop the horizontal drilling techniques that Pemex currently obtains only from foreign contractors. Aside from the value of NSC's well-intended advice to the IMP, the council's vision of the energy challenge of Mexico - and of the specific role the petroleum sector within that challenge - is narrowly conceived

"Is it worth risking your life?" Ethnography, risk and death on the U.S.-Mexico border.

Science.gov (United States)

Holmes, Seth M

2013-12-01

Every year, several hundred people die attempting to cross the border from Mexico into the United States, most often from dehydration and heat stroke though snake bites and violent assaults are also common. This article utilizes participant observation fieldwork in the borderlands of the US and Mexico to explore the experience of structural vulnerability and bodily health risk along the desert trek into the US. Between 2003 and 2005, the ethnographer recorded interviews and conversations with undocumented immigrants crossing the border, border patrol agents, border activists, borderland residents, and armed civilian vigilantes. In addition, he took part in a border crossing beginning in the Mexican state of Oaxaca and ending in a border patrol jail in Arizona after he and his undocumented Mexican research subjects were apprehended trekking through the borderlands. Field notes and interview transcriptions provide thick ethnographic detail demonstrating the ways in which social, ethnic, and citizenship differences as well as border policies force certain categories of people to put their bodies, health, and lives at risk in order for them and their families to survive. Yet, metaphors of individual choice deflect responsibility from global economic policy and US border policy, subtly blaming migrants for the danger - and sometimes death - they experience. The article concludes with policy changes to make US-Mexico labor migration less deadly. Copyright © 2013 Elsevier Ltd. All rights reserved.

The development and evaluation of emissions data for sources located along the Mexico/US border have accelerated over the past few years. This paper examines several new activities in emissions inventory development for the northern border of Mexico. Reviewed in this paper are the following recent developments that will lead to improved inventories for Mexico: development of inventory educational materials; creation of inventory manuals; estimation of emissions for unique sources; emissions-related studies; and identification of key research needs for Mexico inventories. Some of these activities are building a greater capacity in Mexico to construct emissions estimates. These topics are reviewed from the perspective of improving Mexico emissions inventories and emissions estimation capabilities.

Physical Exposure to Seismic Hazards of Health Facilities in Mexico City, Mexico

Science.gov (United States)

Rodriguez, S. M.; Novelo Casanova, D.

2010-12-01

Although health facilities are essential infrastructure during disasters and emergencies, they are also usually highly vulnerable installations in the case of the occurrence of large and major earthquakes. Hospitals are one of the most complex critical facilities in modern cities and they are used as first response in emergency situations. The operability of a hospital must be maintained after the occurrence of a local strong earthquake in order to satisfy the need for medical care of the affected population. If a health facility is seriously damaged, it cannot fulfill its function when most is needed. In this case, hospitals become a casualty of the disaster. To identify the level of physical exposure of hospitals to seismic hazards in Mexico City, we analyzed their geographic location with respect to the seismic response of the different type of soils of the city from past earthquakes, mainly from the events that occurred on September 1985 (Ms= 8.0) and April 1989 (Ms= 6.9). Seismic wave amplification in this city is the result of the interaction of the incoming seismic waves with the soft and water saturated clay soils, on which a large part of Mexico City is built. The clay soils are remnants of the lake that existed in the Valley of Mexico and which has been drained gradually to accommodate the growing urban sprawl. Hospital facilities were converted from a simple database of names and locations into a map layer of resources. This resource layer was combined with other map layers showing areas of seismic microzonation in Mexico City. This overlay was then used to identify those hospitals that may be threatened by the occurrence of a large or major seismic event. We analyzed the public and private hospitals considered as main health facilities. Our results indicate that more than 50% of the hospitals are highly exposed to seismic hazards. Besides, in most of these health facilities we identified the lack of preventive measures and preparedness to reduce their

They say it runs in the family: diabetes and inheritance in Oaxaca, Mexico.

Science.gov (United States)

Everett, Margaret

2011-06-01

The globalization of genetic discourses, especially where ethnicity is treated as a "risk factor" for disease, deserves special attention and concern. In countries such as Mexico, with large indigenous populations, the consequences of the Thrifty Genotype hypothesis and/or the attribution of type 2 diabetes to "family history" may be especially detrimental to poor rural communities, playing as they do into existing racial hierarchies. Based on semi-structured interviews with doctors and patients in a public clinic in a community near Oaxaca, Mexico, the study examines etiologies for type 2 diabetes. While notions of genetic inheritance and family history figure prominently in government and public health discourse, the "explanatory model" of patients places most emphasis on strong emotions, traumatic events, and dietary factors. Clinic doctors emphasize diet and lifestyle factors. The diffusion of "genetic risk" has had little impact on doctor-patient interactions in this community, but can be clearly seen in academic research, government policy, and medical specialties in the region, raising concerns about whether or not interventions will be directed at the social determinants of this growing health concern.

It was not until the last third of the 19th century, the period in which, according to historiography, the country definitely inserted itself into modernity, that anomalies and monstrosities had a presence in Mexico. Therefore, what I present here are four moments of teratology in Mexico, four dates in which I try to recount how teratology, which still occupied a marginal place within the main themes of national science, not only reached to cover the realm of medical discussions at the time, but also laid the foundations for new disciplines like biology and anthropology.

Lindsey, R.

1996-06-01

The high potential costs of compliance associated with new effluent guidelines for offshore and coastal oil and gas operations could significantly affect the economics of finding, developing, and producing oil and gas in the Gulf of Mexico. This report characterizes the potential economic impacts of alternative treatment and discharge regulations for produced water on reserves and production in Gulf of Mexico coastal, territorial and outer continental shelf (OCS) waters, quantifying the impacts of both recent regulatory changes and possible more stringent requirements. The treatment technologies capable of meeting these requirements are characterized in terms of cost, performance, and applicability to coastal and offshore situations. As part of this analysis, an extensive database was constructed that includes oil and gas production forecasts by field, data on existing platforms, and the current treatment methods in place for produced water treatment and disposal on offshore facilities. This work provides the first comprehensive evaluation of the impacts of alternative regulatory requirements for produced water management and disposal in coastal and offshore areas of the Gulf of Mexico

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.

In 50% of cases, such contact is with a boyfriend or girlfriend, 28.1% with a fiance, and 18.3% with a prostitute. First sexual intercourse occurs with a spouse in only 1.3% of cases. Since only one in six young people in Mexico use a form of contraception, many unwanted pregnancies outside of marriage result. 450,000 births in 1989 were to mothers below 20 years old, with 15% of births annually being among teenage mothers. An estimated three million abortions occur annually in Mexico, and abortions are the fifth major cause of death at the national level. Teen pregnancy is decisively linked with poor living conditions and life expectancy, a relatively lower level of education, and rural residence. As for psychological and anthropological variables, most teens who become pregnant belong to large, unstable families with poor family communication, and are characterized as submissive, highly dependent, and of low self-esteem. Targeting students, workers, and other youths, the MEXFAM Youth Program selects and trains program coordinators over age 21 and volunteer promoters of both sexes aged 16-20 in urban/marginal communities. Promoters offer information to their peers and other youths in their local communities, distribute barrier contraceptives, and channel medical, psychological, and legal services to young people in need. Program procedure is described.

Differences and similarities in cancer patterns between the country of Mexico and the United States' Mexican population, 11% of the entire US population, have not been studied. Mortality data from 2008 to 2012 in Mexico and California were analyzed and compared for causes of cancer death among adult and pediatric populations, using standard techniques and negative binomial regression. A total of 380,227 cancer deaths from Mexico and California were included. Mexican Americans had 49% and 13% higher mortality than their counterparts in Mexico among males and females, respectively. For Mexican Immigrants in the US, overall cancer mortality was similar to Mexico, their country of birth, but all-cancers-combined rates mask wide variation by specific cancer site. The most extreme results were recorded when comparing Mexican Americans to Mexicans in Mexico: with mortality rate ratios ranging from 2.72 (95% CI: 2.44-3.03) for colorectal cancer in males to 0.28 (95% CI: 0.24-0.33) for cervical cancer in females. These findings further reinforce the preeminent role that the environment, in its multiple aspects, has on cancer. Overall, mortality from obesity and tobacco-related cancers was higher among Mexican origin populations in the US compared to Mexico, suggesting a higher risk for these cancers, while mortality from prostate, stomach, and especially cervical and pediatric cancers was markedly higher in Mexico. Among children, brain cancer and neuroblastoma patterns suggest an environmental role in the etiology of these malignancies as well. Partnered research between the US and Mexico for cancer studies is warranted. © 2017 UICC.
