    We compiled a checklist of the amphibians and reptiles of the state of Hidalgo, Mexico. The herpetofauna of Hidalgo consists of a total of 175 species: 54 amphibians (14 salamanders and 40 anurans); and 121 reptiles (one crocodile, five turtles, 36 lizards, 79 snakes). These taxa represent 32 families (12 amphibian families, 20 reptile families) and 87 genera (24 amphibian genera, 63 reptile genera). Two of these species are non-native species (Hemidactylus frenatus Duméril and Bibron, 1836 a...

    Full Text Available Mexican Pliocene cervids are very poorly known. We report on new fossil material of the roe deer Capreolus constantini recovered from the Pliocene Atotonilco El Grande Formation of Santa María Amajac, Hidalgo (central Mexico. The specimens were collected from a series of layers of friable to moderately indurated polymictic conglomerate supported by a sandstone-tuffaceous-calcareous matrix. This species was formerly known only from the late Pliocene of Udunga, Russia, thus implying a dispersal event to North America around 4.0 Ma. This cervid is one of the very small number of mammals recorded from the poorly sampled Pliocene temperate deposits of Mexico.

    Full Text Available Históricamente, el aprovechamiento de los bosques ha sido la principal razón que ha motivado la investigación forestal. La búsqueda de información sobre la captura y contenido de carbono, mediante modelos biométricos y tecnología de sensores remotos, se ha incrementado desde el año 2000. El objetivo de este trabajo fue recopilar, sistematizar y analizar los documentos de difusión científica y tecnológica relacionados con los modelos biométricos usados para el manejo forestal en una región del centro de México (Hidalgo. Se encontraron 32 trabajos de investigación generados de 1976 a 2015 que reportan 289 modelos, entre los que resalta el uso de modelos de crecimiento, volumen, biomasa, carbono, índice de sitio, densidad y mortalidad. Los modelos de crecimiento han sido los más estudiados, mientras que los de biomasa y carbono se han incrementado consistentemente desde 2007. El género Pinus ha sido el más estudiado, en cambio Quercus, prácticamente, no figura en los trabajos. Pese a su importancia económica, cinco especies forestales no cuentan con modelos ajustados: Pinus leiophylla, P. michoacana, P. oocarpa, Cupressus lindleyi y Arbutus xalapensis. Los modelos reportados basan su confiabilidad en criterios estadísticos, pero no se reporta si han logrado satisfacer la demanda de los usuarios finales.

    Mexico has the second largest cycad diversity in the world, and the Sierra Madre Oriental (SMO) is one of the richest biogeographic regions for these plants. Despite there is a general Cycad National Program in the country, there are no state-level cycad conservation strategies or programs. Thus the aim of this study was to propose a cycad conservation strategy for the state of Hidalgo, which is located in the Southern part of the SMO. For this, a cycad species inventory was made in the state, for which three methods were used: review of published literature; consultation in the main Mexican herbaria to verify botanical specimens; and exhaustive field research to compare findings with previously reported species and to recognize new records at the county and state level. The proposed research work strategy combined the following elements: prioritize the county and local areas with greatest cycad species richness; prioritize the species least resistant to environmental change and/or having restricted geographic distribution; and to consider the main uses of these plants by local residents. The results showed that Hidalgo has three genera and eight species ofcycads: Ceratozamia fuscoviridis, C. latifolia, C. mexicana, C. sabatoi, Dioon edule, Zamia fischeri, Z. loddigesii and Z. vazquezii, all of which are considered by the International Union for Conservation of Nature (IUCN). This study added two new species records for Hidalgo and 21 at the county level. The species are distributed in 26 counties, of which Chapulhuacán and Pisaflores are notable for their high species richness. Hidalgo has the fourth-greatest cycad species richness among Mexican states, although its area accounts for only 1.07% of the country. The state's diversity is greater than in other states with larger area, and even than in some other entire countries in Mesoamerica. The presented state cycad conservation strategy proposes that a total of some 11,325 ha to be conserved in nine zones

    Several materials with high content of iron oxides and positive electrostatic surface charge were identified as alternative arsenic sorbents. These properties are characteristic for minerals as hematite, geotite, lepodocrocite, maghemite, etc., widely distributed in the rocks of all these types and ages in the land bark. The natural hematite has been selected for a pilot experimental study conducted in one of the underground sources in Mexico. The obtained arsenic effluent concentration was less than 0.05 mg/l, assuring the current water-drinking standard. The effect of the operational rate and the influence of the silica and other contaminants present in the raw water over the removal efficiency of hematite were also evaluated. The obtained results prove the raw water over the removal efficiency of hematite were also evaluated. The obtained results prove the viability of the hematite for arsenic removal in the real field conditions. [Spanish] Varios minerales de alto contenido de hierro y carga superficial positiva se han identificado como sorbentes alternativos del arsenico. Estas propiedades son caracteristicas de algunos minerales como hematita, goetita, lepodocrocita, maghemita, etc., los cuales se hallan distribuidos ampliamente en las rocas de todos los tipos y edades que hay en la corteza terrestre. El presente estudio fue hecho sobre la hematita por su alta capacidad de adsorcion respecto al arsenico, evaluada a nivel de laboratorio, y por ser un mineral natural disponible en Mexico. La hematita fue aplicada para remover el arsenico presente en el agua de una fuente de abastecimiento en Mexico. Los resultados obtenidos en el campo comprueban la eficacia de la hematita en la remocion del arsenico, habiendose registrado una concentracion menor de 0.05 mg/l en el agua producida, lo cual satisface los requisitos de la normatividad para el consumo humano respecto a este contaminante.

    Edible insects are a natural renewable resource that provides food to many ethnic groups in Mexico. Some of these species are overexploited because of increased consumption, caused by the huge human population growth in the area and because of the large demand of these insects from many restaurants in Mexico and in other countries. In Tulancalco, a small arid village in the State of Hidalgo, I carried out studies on edible insects over 25 years. The inhabitants of this village have a natural economy and use some 30 species of insects as food. At present, we have noticed a decrease in the population of several species due to overexploitation, which is carried by non-qualified independent workers who are not natives of the town. These gatherers sell their catch to make a living, thus contributing to the socioeconomic factors associated with this issue. These actions have degraded the ecosystems of this area, and consequently the prevention of these measures is critical. The study species in this paper include 14 threatened species and we discuss some pragmatic measures that could implemented to avoid their extinction. In addition, some actions for the preservation of the ethnoentomobiodiversity in the area are proposed.

Its unique suite of characters, that includes several autapomorphies supports its assignment as a new genus and species, such as the presence of a triangular head with three sides of similar lengths and with its deepest part at the level of the supraoccipital region; the lower jaw projecting anterior to the premaxilla; the ornamentation of cranial bones – especially those of the cheek region – consisting of fine longitudinal crests densely covering the bony surfaces; one or a few deep grooves on the mandibular teeth, which in addition bear acrodin tips ornamented with fine parallel striae; and the position of the dorsal fin, near the posterior margin of the cranium. Motlayoichthys n. gen., together with Michin, Pachyrhizodus, Rhacolepis, and Notelops, is part of the early radiation of pachyrhizodontoids during Albian times.

    Plant establishment, presence of arbuscular mycorrhizal fungi (AMF) and other rhizospheric fungi were studied in mine wastes from Zimapan, Hidalgo state, Mexico, using a holistic approach. Two long-term afforested and three non-afforested mine tailings were included in this research. Fifty-six plant species belonging to 29 families were successfully established on the afforested sites, while unmanaged tailings had only a few native plant species colonizing the surrounding soils. Almost all plant roots collected were associated to AMF in these sites. The genus Glomus was the most abundant AMF species found in their rhizosphere; however, the Acaulospora genus was also observed. Other rhizospheric fungi were identified by 18S rDNA sequencing analysis. Their role in these substrates, i.e. biocontrol, pollutant- and organic matter-degradation, and aides that increase plant metal tolerance is discussed. Our results advance the understanding of fungal diversity in sites polluted with metals and present alternative plants for remediation use. Copyright 2009 Elsevier Ltd. All rights reserved.

    The organochlorine pesticides (OP) are very stable molecules, due to this stability; they are very resistant in the environment and highly related to fat tissues with a wide diffusion property and an average time life higher then 10 years. We studied sediments (November 2001, April and June 2002) and organisms collected in April and July (2002) from the lacustric zone of Metzitlán, Hidalgo, Mexico. The analysis was performed according to UNEP/IAEA (1982) (sediments) and UNEP/FAO/IOC/IAEA (1986) (organisms) methods. Three chemical families of organochlorine pesticides were identified and analyzed to determine posible toxicological risk. The principal organochlorine compounds found in sediments were gamma-HCH, delta-HCH, p,p'-DDT and the endosulfan sulfate; these xenobiotics come from agriculture lands near the river and lake, used intensively, and most probably carried by the rain and rain flows into the main water body. In the tilapias tissue, p,p'-DDD y delta-HCH were detected. The average concentrations of organochlorine pesticides in sediments were within the internacional limits for freshwater benthonic fauna, although lindane (gamma-HCH) was near the limit. The fish were above the criteria established in the local legislation (NOM-027-SSA1-1993 y NOM-028-SSA1-1993).

    A survey was carried out from 2008 to 2010 to determine the concentrations of 16 organochlorine pesticide residues (OPRs) from Tizayuca, Hidalgo, Mexico. Organochlorine residue determinations were made from milk fat, using chromatographic cleanup and analysis by gas chromatography with an electron capture detector. The OPR concentrations found were from below the detection limit (DL) to 0.91 ng g(-1) in 2008, DL to 0.38 ng g(-1) in 2009 and DL to 0.59 ng g(-1) in 2010. In general concentrations of organochlorine pesticides were higher in the wet season (3.37 ng g(-1) and 4.79 ng g(-1)) than the dry season (1.92 ng g(-1) and 2.71 ng g(-1)) for 2009 and 2010, due to control of pests in the pasture and sheds. According to Codex Alimentarius regulations, individual pesticides did not exceed the permissible limits, which for example were 10 μg kg(-)1 for alpha hexachlorocyclohexane (HCH) and endosulfan I, 20 μg kg(-1) for p,p'-DDT, and 6 μg kg(-1) for dieldrin, endrin and heptachlor. A reduction of organochlorine pesticide concentrations in cow's milk was noted, indicating that the Mexican government has achieved reduction or elimination of some organochlorine pesticides in response to global agreements on persistent organic pollutants.

    A manganese (Mn) survey in airborne particulate matter from a mining area located in Hidalgo State (Mexico) was performed using PIXE. Deposits of Mn ore, first discovered in 1959 and under continuous exploitation since 1962, are nowadays considered as one of the most important of their kind in the American Continent. Afterwards, local inhabitants have been under continuous overexposure to dusts and water highly enriched with Mn. Since no information was available about Mn content in airborne particulate matter in that area, especially in the respirable fraction PM 2.5 , airborne particles were collected simultaneously at two sites located on opposite sides of the rim of the mining valley, and along the line of prevailing local winds. The sample collection was performed on eight alternate days, taking two samples per day (day-time and night-time) at each sampling site, using Stacked Filter Units (SFUs) of the Davis design to separate particles into fine (PM 2.5 ) and coarse (PM 15 ) sizes. The samples were PIXE analyzed and the results of this study revealed that Mn content, in both fine and coarse fractions, were in excess of the general urban background level of 40 ng/m 3 (US Environmental Protection Agency, 1990) in more than 50% of the samples, which indicate severe environmental deterioration in the place under study

    Anionic exchange resins were research with respect its capacity for removal arsenic content in water. Water of well V from Zimapan Hidalgo Mexico was used to make this research, because this water have a mean concentration of 480±11μg-L''-1 of arsenic and it is available as drinking water. The exchange resins employed were two strong anionic, one macroreticular (IRA-900) and other gel type (IRA-400), as soon as one third anionic weak macroreticular type (IRA-96). The experiments carried with this resins showing that IRA-900 has highest efficient in the process of arsenic removal from drinking water, because, it showed a treatment capacity of 700 V a gua. V r es''-1; while that capacities of IRA-400 e IRA-96 resins were 320 and 52 V a gua .V r es''-1 respectively. The mean concentration of arsenic residue in the treatise water was 24 μg.l''-1 and it is within the maximum level permissible by Mexican official norm for drinking water. (Author) 12 refs

    Dog overpopulation in developing countries has negative implications for the health and safety of people, including the transmission of zoonotic diseases, physical attacks and intimidation to humans and animals, as well as impacts on canine welfare. Understanding the ecology and demographic characteristics of a dog population can help in the planning and monitoring of canine population control programs. Little data exist regarding demography and dynamics of domestic dog populations in semi-urban areas in Mexico. A cross-sectional study was carried out between October 21 and November 7, 2015, to characterize the dog ecology and demography in Villa de Tezontepec, Hidalgo, Mexico. A face-to-face survey was used to collect data from randomly selected households in four contiguous communities using stratified two-stage cluster sampling. Within each household, adults answered questions related to their dogs and their experiences with dog bites and aggression. A total of 328 households were interviewed, representing a participation rate of 90.9% (328/361) and 1,450 people. Approximately 65.2% of the households owned one or more dogs, with a mean of 1.3 (SD=1.5) and 2.0 (SD=1.5) owned dogs in all participant households and dog-owning households, respectively. The human: owned dog ratio for all participant households was 3.4:1 (1450/428), and for the dog-owning households was 2.3:1 (984/428). The owned dog male: female ratio was 1.4:1 (249/179). Approximately 74.4% (95.0% CI=69.8% - 78.7%) of the owned dogs were older than one year (mean age: 2.9 years; SD=2.5). The mean age of owned female dogs at first litter was 1.9 years (SD=1.2) and the mean litter size was 4.2 puppies (SD=2.1). Approximately 36.9% (95.0% CI=31.8% - 46.4%) of the females were spayed, and 14.1% (95.0% CI=10.7% - 19.7%) of the males were neutered. Only 44.9% (95.0% CI=40.1% - 49.7%) were always confined when unsupervised. Approximately 84.4% (95.0% CI=80.6% - 87.7%) were reported to have been vaccinated

    Full Text Available The organochlorine pesticides (OP are very stable molecules, due to this stability; they are very resistant in the environment and highly related to fat tissues with a wide diffusion property and an average time life higher then 10 years. We studied sediments (November 2001, April and June 2002 and organisms collected in April and July (2002 from the lacustric zone of Metzitlán, Hidalgo, Mexico. The analysis was performed according to UNEP/IAEA (1982 (sediments and UNEP/FAO/IOC/IAEA (1986 (organisms methods. Three chemical families of organochlorine pesticides were identified and analyzed to determine posible toxicological risk. The principal organochlorine compounds found in sediments were g-HCH, d-HCH, p,p’-DDT and the endosulfan sulfate; these xenobiotics come from agriculture lands near the river and lake, used intensively, and most probably carried by the rain and rain flows into the main water body. In the tilapias tissue, p,p’-DDD y d-HCH were detected. The average concentrations of organochlorine pesticides in sediments were within the internacional limits for freshwater benthonic fauna, although lindane (g-HCH was near the limit. The fish were above the criteria established in the local legislation (NOM-027-SSA1-1993 y NOM-028-SSA1-1993. Rev. Biol. Trop. 56 (3: 1381-1390.

    Blood-feeding arthropods play a major role in the transmission of several flaviviruses, which represent an important problem for human health. Currently, dengue is one of the most important arboviral emerging diseases worldwide. Furthermore, some previous studies have reported the presence of viral nucleic acids and antibodies against dengue virus (DENV) in wild animals. Our knowledge of the role played by wildlife reservoirs in the sylvatic transmission and maintenance of DENV remains limited. Our objective was to screen blood-feeding ectoparasites (bat flies) and their common vampire bat (Desmodus rotundus) hosts, for flaviviruses in Hidalgo, Mexico. We detected Flavivirus sequences in 38 pools of ectoparasites (Diptera: Streblidae, Strebla wiedemanni and Trichobius parasiticus) and 8 tissue samples of D. rotundus by RT-PCR and semi-nested PCR using FlaviPF1S, FlaviPR2bis, and FlaviPF3S primers specific for NS5, a gene highly conserved among flaviviruses. Phylogenetic inference analysis performed using the maximum likelihood algorithm implemented in PhyML showed that six sequences clustered with DENV (bootstrap value = 53.5%). Although this study supports other reports of DENV detection in bats and arthropods other than Aedes mosquitoes, the role of these ectoparasitic flies and of hematophagous bats in the epidemiology of DENV still warrants further investigation.

    Miguel Hidalgo Hospital in Aguascalientes is dependent from the Federal Secretary of Health and operates in integrity with State health system in Aguascalientes. It capacity is based on 132 censored beds and 71 no censored beds. Is considered a specialty hospital in the region of Bajío. Renal transplant program activity was initiated in 1990 and gives care for adult and pediatric population. Retrospective, comparative and longitudinal study to describe and analyze our experience. Data base and clinical charts of renal transplant recipients were reviewed. Age, gender, date of transplant, etiology of renal disease, type of donor, HLA compatibility and PRA, immunosuppressive therapy, acute rejection, serum creatinina, graft loss and mortality were registered. Statistical analysis included 2, unpaired Student T test and Kaplan-Meier survival analysis with Log Rank test. Cox Analysis was also done. 1050 renal transplants were done from November 1990 to June 2011. 50 were excluded because follow-up was not longer than 3 months. 1000 consecutive renal transplant patients from January 1995 to June 2011 were included for analysis. Patients were divided in 2 groups: group A transplanted January 1995 to December 2004; group B transplanted January 2005 to June 2011. Etiology for end stage renal disease is unknown in 61% of cases, 11% developed renal disease to diabetes mellitus. 93% patient survival was observed at median follow-up and 84.9% graft survival at median follow-up (6 years). Biopsy proven acute rejection in group A 19.9 vs. 10% in group B. Two haplotype matching shows 92% graft survival. Diabetic patients exhibit 73% graft survival vs. other as hypertension (87%). PRA >0 and serum creatinine > 2.0 mg/dL increase risk for graft loss according to Cox analysis. CONCLUSION. Results are comparable to international data. Importance of developing regional transplant centers is emphasized.

    The mining district Pachuca-Real del Monte is located to the center-east of Mexico, between the geographical coordinates 20 degrees celsius 07 minutes 30 seconds north latitude and 98 degrees celsius 44 minutes 00 seconds of length west. The residues are derived from an epithermal mineralization. Concentrations of Pb and the Mn are significant. The mineralization is consisted of pyrite, limonite-goethite-hematite, sphalerite, galena, and chalcopyrite associated with quartz, calcite and silicates. X-rays diffraction patterns have determined quartz as the mayor mineral phase, with minor gypsum, calcite, alunite, and pyrite. The statistical analysis has presented the frequent association of Zn-Cd. The microanalysis with the scanning electronic microscope and electronic microprobe have showed the neoformation of the pyrite and the oxidation and precipitate of sulfides. The tests NOM-053 and EPA-1312 have showed that the Cd, Ni, Ag, Pb Mn, Zn, and As do not exceed the LMP. Only the Pb has been superior to the LMP in the first test. These residues might be classified as dangerous with regard to the Pb. (author) [es

    The central objective of this work is to model the quality of the water of Tula River, from the central emitter to their confluence with the Endho Dam. It was evaluated during two years, considering a length of 50 km in 4 zones and 35 sites of sampling. The central emitter contributes to the greater amount of organic matter, water without treatment of the city of Mexico and co urbane zone. The values of DBO varied from 1.16 up to 486.81 mg O 2 /L; the oxygen dissolved between 1.52 and 5.82 mg/L. This implies affectation for the development of the aquatic life. The alkalinity exceeded the ecological criteria of quality as a source of potable water with value of 458.01 mg. the fats displayed variations from 0.9 mg/l up to 18.1 mg/l and ammoniacal nitrogen outside the limits established for protection of the aquatic life with values from 0.09 a 64 mg/L; nitrates (6.24 mg/L) and nitrites (0.5-1.304 mg/L) exceed the ecological criteria. The metals cadmium, lead, iron, manganese and zinc are in concentrations over the permissible rank and in some sections mercury presence was reported. The fecal coliforms were detected in values from 2.1x10 4 up to 2.40x10 1 1 NMP/100 milliliters. In general, the toxicity in the residual water unloading demonstrated that all appears of moderate to high. Only there were three monitored stations (19%) with excellent quality, 3 smaller or equal DBOs to mg/L, which is considered like water no contaminated by biodegradable organic matter

    Current global changes are putting both biodiversity and the processes that depend on it at risk. This is especially true for semi-arid regions and the flagship groups that inhabit them, such as amphibians and reptiles. Semi-arid regions are often thought to have lower biodiversity and thus have been overlooked, resulting in the underestimation of their biological richness. Therefore, the aim of this study was to conduct an inventory of amphibians and reptiles in the semi-arid municipality of Nopala de Villagrán, Mexico, and analyze its biodiversity in relation to the seasons, vegetation and microhabitat. During a year of fieldwork, we found 24 species in the area, most of them of low abundance, and one of which was recorded for the first time for the state of Hidalgo. We documented five amphibian species and 19 reptile species. We also found that observed species richness was higher in the rainy season and in xeric scrub vegetation, although only the season differences were significant according to rarefaction curves. Our findings highlight the importance of seasonality and vegetation type for the species that inhabit this semi-arid region. This study broadens our understanding of the importance of semi-arid regions and, by extension, that of other areas with similar characteristics.

    Geological environments present in southwestern New Mexico include thick sequences of sedimentary rock including limestone, conglomerates, sandstone, and shale: igneous intrusions with associated metal deposits; caldera centers, margins, and outflow facies; and basins with marginal faults and thick late Cenozoic sedimentary fillings. Predominant rock types are Paleozoic carbonates, Mesozoic terrigeneous rocks and carbonates, and Cenozoic volcanic rocks and basin-filling terrigeneous rocks. Consideration of information available in Preliminary Reconnaissance Reports and in Hydrogeochemical and Stream Reconnaissance Reports together with 347 new whole rock chemical analyses points to three areas of anomalous uranium abundance in Hidalgo County, New Mexico. The area has experienced three major periods of igneous activity in Phanerozoic time: one associated with the Laramide cycle of the Late Cretaceous and early Tertiary, mid-Tertiary cycle of silicic volcanism with abundant calderas, and a late Tertiary cycle of mafic volcanism. Silicic volcanic rocks are the most common exposed rock type in the area, and the most enriched in uranium (range, 0.4 to 19 ppM). The most likely source for any uranium ore-forming solutions lies with this cycle of volcanism. Solutions might have been introduced during volcanism or formed later by groundwater leaching of cooled volcanic rocks. Results indicate that groundwater leaching of cooled volcanic rocks was not an effective means of mobilizing uranium in the area. Study of several rhyolite lava flows indicates that they were emplaced in supercooled condition and may have crystallized completely at temperatures well below their liquids, or they may have warmed as crystallization released latent heat. Statistical comparison of the uranium concentration revealed no differences between vitrophyres and associated felsites.

    Full Text Available The objective of this study was to show an in vitro bioremediation methodology for atrazine-contaminated soils through the use of local strains of native fungi isolated from the Phaseolus vulgaris L rhizosphere present in cultivable soils as well as to evaluate its resistance and capacity for atrazine degradation. A Trichoderma sp. species was identified in three cultivable soils from the Tulancingo Hidalgo, México region (contaminated with and without atrazine, which resisted atrazine concentrations of 10,000 mg L-1.  Tests showed that the strain grows exponentially in atrazine-contaminated soil over a range of 105-106 CFU g-1 in 15 days using atrazine as the only carbon and nitrogen source, while the control and witress showed a decrease of 100-103 UFC g-1 in the same period of time. For the atrazine degradation experiments, a treatment of the application of Trichoderma (104 - 105 CFU mL-1 was applied to sterilized and non-sterilized soil contaminated with 500 mg Kg-1 of atrazine, evaluated at four time intervals (5, 10, 20 and 40 days. Statistical differences were found (α=0.050, Tukey among treatments with the fungi and the test days. The native Trichoderma strain degraded 89% of the atrazine in 40 days. It showed that it is viable and cultivable in soil bioremediation.

    The people in Mexico still depend upon the use of medicinal plants to treat simple health problems, including those who live in regions like Tlanchinol Hidalgo, where it is still possible to find people who speak the pre-Hispanic Nahua language. This area is surrounded by rain forest, which is more or less well conserved, so ethnopharmacological field studies are quite relevant. The cultural knowledge about the use of medicinal plants converge with the richness in the surrounding flora making this region ideal for the selection of traditionally used medicinal plants. To present the results of an ethnopharmacological field survey conducted in the municipality of Tlanchinol Hidalgo, Mexico analyzed with two different quantitative tools, with the aim of selecting the most important species used in traditional medicine. Direct interviews with the people were performed in several short visits to the municipality of Tlanchinol Hidalgo. The plants were collected, and the species were determined. The interviews were analyzed with two quantitative tools. First, the factor informant consensus highlighted the agreement in the use of plants and the fidelity level defined as: the ratio between the number of informants who independently suggested the use of a species for the same major purpose and the total number of informants who mentioned the plant for any use. Furthermore, we analyzed the use-mentions for the plants. The results of the factor informant consensus showed that the gastrointestinal category had the greatest agreement, followed by the respiratory and dermatological categories. The most important species according to their fidelity are: Coleus blumei, Plantago australis and Lippia dulcis for the gastrointestinal category; Borago officinalis, Foeniculum vulgare, and Eucalyptus globulus for the respiratory category; and Ageratum houstonianum and Solanum nigrescens for the dermatological category. As a result of the present study, we recommend the plants listed in

    Air quality mexican regulations about atmospheric aerosols refer to particle sizes and to the total suspended particle. None of these norms establishes the allowed values based on the particulate chemical composition. Mexican environmental legislation also considers as critical zones those with high concentration of contaminants in the atmosphere. One of these zones is the Tula-Vito-Apasco corridor where no chemical composition characterization in terms of trace metal associated to the air particulate matter has been made. Along this corridor near Tlaxcoapan there are important contaminant sources as petrochemical and electric power plants, metal-mechanical industry, limestone quarry and contaminated soils. In this work PIXE and Sem-EDS were applied to the PM 10 fraction collected on filters. The trace element values thus determined were compared with those of a similar critical zone. It was found that most of the coarse particles come from limestone quarry as fugitive dusts while V, Ni, Cr and Pb values are moderately high and seems to be associated to industrial activities and contaminated soil as well.

To determine the prevalence of alcohol and drug consumption and its relationship to sociodemographic variables, leisure activities, antisocial behavior, family norms and conflicts, among others. MATERIAL AND METHODS. Data derive from a representative survey of 1 929 students of junior high and high school, conducted in 1996 in the city of Pachuca, Hidalgo, Mexico. Of these, 44.9% were boys and 52.5% were girls; mean age was 14. A self-applied questionnaire, prepared by the WHO together with some countries, among them Mexico, was completed by the studied subjects, and included indicators of alcohol and drug consumption. RESULTS. Of the total sample, 47.9% had tried alcohol, and 12.6% had drunk large quantities -5 drinks or more per sitting- during the month previous to the survey. Preferred drinks are beer and "coolers", which they buy at shops where no identification is required and drink at home or at friend's homes. With respect to drugs, 5.1% had tried illegal or medical drugs without prescription, in particular inhalants, marihuana and tranquilizers. More boys consumed illegal drugs, and more girls medical drugs without prescription. Boys, who are also older, more frequently consumed alcohol and drugs and were more often employed during the previous year at part-time jobs. High alcohol level and drug consumers were characterized by their frequent report of being bored in their free time, drinking with friends and enrolling in antisocial behavior. With respect to family norms, they follow them less and show less interest in

    Given this background, this paper is focused on the generation of geographic information for regional urban planning and the overall aim is to examine urban growth rate during the period 2000-2014 in the state of Hidalgo, Mexico and identify potential areas of expansion from Landsat images. The methodology was based on techniques of remote sensing and Geographical Information System (GIS. The inputs used were six Landsat scenes: three for 2000 year and three for 2014. Image processing was performed on ERDAS Imagine® 9.1 and the spatial analysis of urban coverage statewide on ArcGIS 10.0 by ESRI®. First, the radiometric correction was made and we obtained the urban polygons of the 2000 year through of supervised classification. The 2014 urban layer was digitized manually due to the spectral incompatibility between the bands of the Landsat sensor 5 and 7, and the Landsat sensor 8. Then, we build a road density map and the spatial relationship of the urban centers with the road influence area was evaluated. For the year 2000, 103 urban polygons were mapped, whilst for 2014 were identified ten polygons more with a mapped minimum area of 24 ha. The main results indicated that in the state has increased 72.3 km2 urban area from 2000 to 2014. This represents an average growth rate of 1.8% per year. The most widespread municipalities are located in the region of Valle del Mezquital, however, Mineral de la Reforma, Tetepango, Tizayuca and Pachuca showed growth rates of 183.44%, 102% 94% and 68.5% in fourteen years, respectively. According to the road map density, these municipalities are located in areas of greatest influence of infrastructure as the Arco Norte highway in the state. The above findings, lead us to conclude that the Mezquital Valley and the Basin of Mexico are potential areas of urban spreading and it is associated with road development in the Central Mexico.

    Full Text Available This paper explores the differences between Conflict and Violence report in two groups: women have experienced Intimate Partner Violence and women with no report; residents in Hidalgo, Mexico. The Conflict and Intimate Partner Violence (IPV scales were applied into a 619 participants, 314 attended health services for experience IPV, while 305 were users of medical care. We use a 3 * 2 design with Relationship Status (Courtship, Married and Cohabitation and sample type (IPV report/ without IVP report. The results demonstrate that women in dating relationships report more conflict related to jealousy compared with women in marriage or cohabitation. Meanwhile, all conflict areas are more reported for women that have experienced violence, with no differences by partner status.

    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.

    This paper describes a strategy for the hydrodynamic modeling of the pathogen intrusion phenomenon in water distribution systems by the combination of a breakage with a depression situation. This scenario will be modeled computationally and experimentally. The phenomenon to be represented by both simulations is the same: the entrance of an external volume into the circulation of a main volume, known as a pathogen intrusion, as long as the main volume is potable water. To this end, a prototype and a computational model based on Computational Fluid Dynamics (CFD) are used, which allow visualizing the fields of speeds and pressures in a simulated form. With the comparison of the results of both models, conclusions will be drawn on the detail of the studied pathogen intrusion phenomenon. [Spanish] En el presente documento se describe una estrategia de modelacion del fenomeno hidrodinamico de la intrusion patogena en redes de distribucion de agua por combinacion de una rotura con una situacion de depresion. Este escenario sera modelado computacional y experimentalmente. El fenomeno que se desea representar con ambas simulaciones es el mismo: la entrada de un caudal externo a una conduccion para la que circula un caudal principal, denominado intrusion patogena, siempre y cuando el caudal principal sea agua potable. Para ello se dispone de un prototipo y un modelo computacional basado en la Dinamica de Fluidos Computacional (DFC de aqui en adelante), que permite visualizar los campos de velocidades y presiones de forma simulada. Con la comparacion de los resultados de ambos modelos se extraeran conclusiones sobre el detalle del fenomeno de la intrusion patogena estudiado.

    Full Text Available RESUMEN: La figura de José Luis Hidalgo (Torres, 1919-Madrid, 1947, poeta y pintor, ha de tomar un nuevo relieve como representante de una generación de autores montañeses que surgió en torno a los años cuarenta. Destaca en su breve obra, al igual que su corta pero intensa vida, la extrema sensibilidad de su poesía en el uso de imágenes, metáforas que acercan sus versos hacia el terreno de lo plástico y sensorial. Las preocupaciones son de profunda raigambre existencialista, al ser nuestro poeta un joven lector de pensadores como Nietzsche, Schopenhauer o Unamuno; es con este último con el que guarda una ineludible afinidad de ideas. La búsqueda que emprende José Luis Hidalgo hacia la verdad se sitúa dentro de una metafísica trascendente y una vertiente religiosa muy significativa, en un diálogo sincero y directo con Dios. Contrasta la sencillez formal de su poesía con el complejo sistema simbólico de elementos naturales, espacios... en los que se mueve dentro del marco fluctuante entre la tradición y la vanguardia; encontramos resonancias que nos llevan desde el romanticismo becqueriano, pasando por el simbolismo, hasta los movimientos vanguardistas —sobre todo el surrealismo— y el grupo poético del 27. La obra de Los muertos supone un momento culmen del dilatado periodo de posguerra.ABSTRACT: The literary figure of José Luis Hidalgo (Torres, 1919-Madrid, 1947, both a poet and a painter, achieves renown once more as a representative of a generation of writers from Cantabria (in the north of Spain which came to light around the 1940's. His work, as brief as his short but intense life, is remarkable for the great feeling of his poetry in the use of imagery and metaphors, which draw his verse near the domain of the vivid and sensorial. His concerns have deep existentialist roots; as a young man the poet was a devoted reader of great thinkers such as Nietzsche, Schopenhauer or Unamuno; it is the latter with whom he has an

    This study presents the hydrogeologic model of the Apan-Tochac sub-basin, obtained from geologic and geo electric soundings. These data were interpreted with the lithological description of three well-logs. This information allows to identify and map three different aquifers: intergranular, fissure and mixed. These three aquifers are hydraulically connected. The first one is located in the discharge zone and has semi-confined conditions in the center of the Tochac plain and is unconfined toward the periphery of the same plan. The other two aquifers are located mainly in the recharge zone. The hydraulic conductivity values are: 3x10-3 ms{sub 1} a 10-4 ms{sub 1} for the intergranular aquifer, 3x10-3 ms{sub 1} for the fissured and the third aquifer has not data available but it is assigned a value of 2x10-6 ms{sub 1}. The chemical analyses of groundwater (anions and cations) indicate that its mineralization forms two hydrochemical facies: a low mineralization facies corresponding to the recharge area, and a high mineralization facies corresponding to the discharge zone. The results also show that groundwater is of good quality for human consumption (Secretaria de Salubridad y Asistencia, and the World Health Organization), except for the concentrations of lead and chromium due to incipient contamination. Therefore, it is necessary to start actions to protect the aquifers and to foresee possible damages in the health of the inhabitants of the region, which use this groundwater. The preliminary hydrogeologic balance shows that the aquifer system of this sub-basin is almost in equilibrium. [Spanish] Este estudio presenta el modelo hidrogeologico de la subcuenca Apan-Tochac, apoyado en la informacion geologica y sondeos geoelectricos, interpretados estos ultimos con la descripcion litologica de tres perforadores. De esta forma, se reconocio y cartografio los siguientes acuiferos: (i) intergranular, (ii) fisurado y (iii) mixto. Estos tres acuiferos tienen relacion hidraulica. El primero forma la zona de descarga, es de tipo semiconfinado hacia el centro de la planicie Tochac y de condicion libre hacia la periferia de la misma. Los dos ultimos se localizan en la zona recarga principalmente. Los valores de la conductividad hidraulica son: 3x10-3 ms-1 a 10-4 ms-1 para el integranular, 3x10-3 ms-1 para el fisurado, el tercero no tuvo datos, pero se le asigno un valor de 2x10-6 ms-1. El analisis de los aniones y cationes del agua subterranea indica que por su mineralizacion existen en esa subcuenca dos facies hidroquimicas: (a) baja mineralizacion, que corresponde a la zona de recarga, y (b) alta mineralizacion, correspondiente a la zona de descarga, manifestando la direccion del flujo del agua subterranea. Asimismo, de acuerdo con la norma de calidad del agua (mexicana y de la Organizacion Mundial de la Salud), el agua de esta area es de buena calidad para consumo humano; la presencia de Pb y Cr en el agua de varios pozos, manifiesta que es preciso iniciar acciones para proteger los acuiferos y prever posible dano en la salud de la poblacion de esta zona. El balance hidrogeologico preliminar muestra que el sistema acuifero de esta subcuenca esta casi en equilibrio.

    A sulfide-type mineral of the district of Zimapan, Hidalgo, Mexico, was chemically and mineralogically analyzed with the aim of detecting minor species with added value for their subsequent beneficiation. Apart from the usual species of the site, the X-ray diffraction analysis (XRD) detected the presence of tungsten sulfate (WS2) and the mineral species typical of a base-metal sulfide site, as well as impurities such as: orthoclase, quartz, magnesium-silicon oxide, magnesioferrite, monticellite, andradite, magnetite and calcite, the latter being the mineral matrix. The Scanning Electron Microscopy (SEM) mapping confirmed the presence of the typical elements of the mineral: W, Si, O, Mg, Ca, C, Al, K, Fe, S, Zn and Cu. The Inductively Coupled Plasma Spectroscopy (ICP) analysis indicates an average concentration of 380 g W ton"1, as well as 1.81% Zn, 3.41% S, 0.15% Cu, 2.36% Fe, 0.78% Pb, 0.04% Mn, Sb 0.05% and 0.01% Ag.

El análisis de las voces en su contexto desecha la pertinencia de los usos relativos a la ingeniería y atestigua el sentido humanista de la palabra, pero, dentro de este, muestra una gradación de sentidos que no se da en la actualidad. En la obra cervantina el término ingenio comporta una oscilación semántica cuyo sentido específico solo se revela por medio del acompañamiento léxico de un adjetivo. Sin embargo, el adjetivo ingenioso muestra, en apariencia, un cierto grado de ambigüedad que ha hecho que se le asocie con la locura en aplicación a El Quijote. El análisis de los diversos usos y aplicaciones que Cervantes concede a tales términos en su referencia al hidalgo arrojan claramente un sentido positivo de singularidad y brillantez de una mente idealista en contraste al mundo material en torno al que se mueven los demás personajes.Este artigo incide sobre os termos engenho e engenhoso no contexto de Dom Quixote através da sua relação com o humanismo - o brilho da mente -, a engenharia - como um subproduto da criatividade humana - e o duplo sentido que pode envolver o termo - a sua relação com a falta de juízo mental. A análise dessas palavras em seu contexto descarta a relevância das aplicações de engenharia e atestam o sentido humanista da palavra, mas, neste, mostrando uma gradação de sentido que não acontece hoje em dia.

Determinar la prevalencia del consumo de drogas y bebidas alcohólicas entre estudiantes, así como la relación de este consumo con variables sociodemográficas, tiempo libre, actos antisociales, normas y conflictos familiares, entre otras. MATERIAL Y MÉTODOS. Los datos se derivan de una encuesta representativa de 1 929 estudiantes de enseñanza media y media superior de la ciudad de Pachuca, estado de Hidalgo, México, levantada en 1996, de los cuales 44.9% son hombres y 52.5% mujeres, con una media de edad de 14 años. Se utilizó un cuestionario autoaplicable, que incluye indicadores de consumo de drogas y alcohol elaborados por algunos países, entre ellos México, con la Organización Mundial de la Salud. RESULTADOS. El 47.9% ha probado bebidas alcohólicas; 12.6% bebieron cantidades considerables -cinco copas o más por ocasión- durante el mes anterior a la encuesta. Las bebidas preferidas son la cerveza y los coolers; el alcohol lo compraron principalmente en tiendas donde no les piden identificación y lo consumen en su casa o en la de otras personas. El 5.1% ha consumido drogas, sobre todo inhalables, mariguana y tranquilizantes. Una cifra mayor de varones consume drogas ilegales, y las mujeres, medicamentos sin prescripción. Un número superior de hombres toma más cantidades de alcohol y consume drogas, tienen mayor edad y trabajaron de medio tiempo durante el año anterior a la encuesta. Los consumidores de drogas y de altas cantidades de alcohol se distinguieron porque un número considerable informó que se aburría en su tiempo libre, se va a beber con sus amigos o ha cometido actos antisociales. Respecto a la familia, manifiestan cumplir menos con las normas parentales y muestran menor interés en hacerlo. Asimismo, un porcentaje más elevado informó que sus padres pelean con frecuencia, han pedido ayuda por esa razón y han intentado separarse. CONCLUSIONES.

    Full Text Available This article examines the sectoral performance of the economy of Hidalgo County, Texas, using as reference the 2007–2011 recession period of the U.S. economy. The results of the investigation show that Hidalgo County avoided the contraction of the U.S. employment rate of –4.4%, as evidenced by a positive local employment rate of 5.2%. This recession–proof profile is explained by its orientation toward a service economy, including the public administration sector as a strategic field for correcting market failures. The shift–share technique was applied to provide an account of sectoral performance, supplied with data from the U.S. Bureau of Labor Statistics. The data obtained are discussed in the framework of the theoretical discussion related to the implementation of Keynesian–style active policies.

    This work presents the state of art of the behavior of buried pipelines facing the effect of the propagation of seismic waves. Special attention has been given to the modeling of the soil-piping system. Some analytical models are presented and discussed in great detail. The purpose of this is to contribute, in particular, to the following aspects: First, it attempts to be a reference work for the geotechnical engineers facing problems related to the seismic wave propagation phenomenon in buried structures, since within the consulted literature there are many of the principles presented in here, that are related with the seismic engineering, the reaction module, as well as expressions or investigations performed in piles. Second, a cuasi-static numerical model is presented that analyzes the continuous piping through a stress vector of sinusoidal type. The analysis of the stresses and deformations that the ground transmits to the pipe is made using a ground-to-pipe interaction model. For a low level of deformations an elastic behavior of transference in the interface is considered in the inter-phase ground-piping. In the case of greater deformations it is assumed that sliding is presented because the surrounding ground presents fault by shearing stress in the surrounding ground. The analysis covers solely the case with axial deformations in straight sections. Finally, it intends to give a series of recommendations for future research works on the modeling of buried pipelines. In this work, the influence of several aspects on the response of the pipelines to the propagation of seismic waves is analyzed and discussed; such as the conditions of topography, geology, ground stratigraphy and the rigidity changes in the surrounding ground of the pipe.

    detalle en la quimica de los datos pueden conferir una informacion conflictiva o sesgada. La aproximacion al problema pudiera no tener bases solidas. No es sino hasta que el esfuerzo de medicion se complementa con una modelacion detallada de la meteorologia y la calidad del aire que puede asegurarse el adecuado uso de la informacion de mediciones. Con el fin de comprobar lo anterior, se hizo una estimacion de la utilidad de las mediciones de calidad del aire de una manera sencilla a traves de la construccion de graficas tridimensionales que llamamos isopletas de ozono usadas para relacionar las mediciones de oxidos de nitrogeno (NO{sub x}), compuestos organicos volatiles (COV) y maximos de ozono (O{sub 3}) para tres sitios de la Ciudad de Mexico. El ejercicio consiste en interpretar el transporte de la contaminacion atmosferica en el Valle de Mexico utilizando solamente los datos medidos y nuestras isopletas junto con sus correspondientes datos de rosas de los vientos. Esta interpretacion -la basada en la informacion de mediciones unicamente- esta sujeta a influencias locales y se compara con resultados recientes de modelacion que muestran que cuando los datos medidos se usan en conjuncion con la modelacion de la calidad del aire, se puede obtener una mejor comprension del problema de la contaminacion atmosferica. Una estrategia correcta para estudiar el problema de la contaminacion del aire, especialmente en el caso de la Ciudad de Mexico donde meteorologia y uso de suelo complejos estan presentes, debe ser aquella en la que ambos componentes, modelacion y medicion, se persigan con igual vigor.

  11. The Authors of the Ingenious Hidalgo Don Quixote of La Mancha

    Full Text Available Even today literary criticism still considers the novel Don Quixote the first modern European novel because it fundamentally changes both the concept of literary creation and the findings regarding literary reception. Miguel de Cervantes Saavedra published the first part of his chivalric novel in 1605 in Madrid with the title El ingenioso hidalgo don Quijote de la Mancha. He published the second part, titled El ingenioso caballero don Quijote de la Mancha, ten years later (i.e., in 1615, again in Madrid. Why did Cervantes change the title in the second part of his novel and thus transform Don Quixote the hidalgo ‘nobleman’ into Don Quixote the caballero ‘knight, nobleman, horseman’? In Spanish literature of Cervantes’ time, writers often borrowed texts from one another, wrote sequels to them, and reworked them into humorous poems, jocular one-act plays, or unusual parodies. The Baroque concept of imitation was not understood as plagiarism, but rather as a positive approach to creativity. One of Cervantes’ most enthusiastic imitators was Alonso Fernández de Avellaneda. He hated Cervantes, but loved Don Quixote so much that he wrote a sequel to it in the form of a chivalric novel. In 1614, Avellaneda published his novel titled Segundo tomo del ingenioso hidalgo don Quijote de la Mancha (The Second Part of the Ingenious Hidalgo of La Mancha in Tarragona. Who is hidden behind the name Alonso Fernández de Avellaneda? To date, literary history has not been able to establish with certainty who the author of this “second part” was; this work represents the greatest literary mystery of all time in Spanish literature. In the 1960s a theory developed among Cervantes experts that for now seems to be the most convincing in determining Avellaneda’s true identity. In his article “ El Quijote y los libros” (Don Quixote and Books of 1969, Martín de Riquer presented the first well-founded hypothesis claiming that the writer Alonso Fern

    2010-01-01

    In order to determine the risk of transmission of Trypanosoma cruzi by triatomines in Metztitlan municipality, Hidalgo State, Mexico, entomological indexes were calculated and the characteristics of dwellings were described. A transversal, retrospective, descriptive, and observational study was performed by means of an intentional not probabilistic and expertise sampling from January to December of 2005 in 10 localities in which presence of triatomines were investigated either intra or peridomestic environmental in 699 houses. Building material and presence of infected triatomines with T. cruzi were registered to determine entomologic indexes. The triatomine species collected were: Triatoma barberi (Usinger) and T. mexicana (Herrich-Schaeffer) (Hemiptera: Reduviidae). The results indicated that natural infection index varied from 7.7% to 50%; colonization index reached 80%; infestation index varied from 7.7% to 25%; dispersion index was 70%. Stone-walled houses were more infested. We can conclude that it is necessary to establish T. cruzi transmission control measures against triatomines in localities from Metztitlan, primarily in stone-walled houses where T. barberi occurs, as it was the most important vector species in the transmission of T. cruzi in this municipality.

    In the last 50 years have been enormous changes and the archaeology has been benefited with the technology development, as computation, the advancements in nuclear physics, the electron microscopy, the particle accelerator and the DNA analysis. As first approach to studied material it was realized in cabinet the morphological and technological analysis to establish a typology and to know the manufacturer process of the scrapers (tool used for to scrape a cavity after cutting its lance-shaping leaves at the maguey core obtaining so the sap commonly named hydromel at the Hidalgo state region in Mexico). On the other hand the studies which carried out in the ININ consist in the functional analysis of use traces in scanning electron microscopy (Sem) and stereoscopic to know about the type of work which were addressed the scrapers. Also were carried out the Neutron Activation Analysis (NAA) and the Proton Induced X-ray Emission (PIXE) with the purpose to know the obsidian site which was supplied the Dominion population.

    Samples of clays from Actopan, Hidalgo employed in brick manufacturing are physical, chemical and mineralogical characterized. Transmitted polarized light microscopy showed a uniform particle size with grain morphology characteristic of euhedral crystals with quartz, feldspars, nontronite, and iron oxides particles. Scanning Electron Microscopy revealed 75 μm to 90 μm wide subhedral structures formed by particles from 2.0 μm to 5.0 μm; and rombohedrales forms 40 μm wide, 70 µm long, constituted of silicon, aluminum, iron, titanium, calcium, minor amounts of potassium, magnesium, and sodium. Minerals such as quartz, albite, cristobalite, calcium and Hematite phases were recognized by X-Ray Diffraction technique. Chemical analysis by atomic emission spectrometry with Inductively Coupled Plasma confirmed this mineralogy composition while laser granulometry method found the same particle size. Grain size analysis determined submicrometric dimensions, and multimodal type curves, that can be interpreted as the mixing of two or more different mineral phases in each sample. (author)

    Full Text Available For decades, the State of Hidalgo has been considered as an entity with deep social inequalities and scant social, economic and political development. As a result, there are conditions of exclusion, marginalization, racial discrimination and unequal access to the fundamental rights of its citizens; which are still present in the population census data published by Inegi 2000 and 2005.In the State of Hidalgo there are more than 4596 localities, of which 96% are less than 2500 inhabitants; the great majority of them are located in marginal «municipios» and regions and therefore they do not have the minimum indispensable conditions of welfare. But it is not only poverty but exclusion and vulnerability which affect these communities.In the sierra of Tepehua (San Bartolo Tutotepec, Huehuetla y Tenango, the rural communities, mostly indigenous, with agricultural economic vocation live in marginal conditions and the middlemanism —coyotaje— is a persistent flagellum that occurs even in public organisms.

The treatment aims to relieve symptoms, maintain metabolic control, prevent complications and improve quality of life. Goal: to evaluate the effect of a program of health education in patients with type 2 diabetes mellitus as part of non-pharmacological treatment. Methodology: a before-after quasi-experimental design was conducted. 13 patients with type 2 diabetes mellitus were included. Socio-demographic aspects and their level of knowledge about the disease were assessed. They received an educational program regarding nutrition, exercise and stress management. This program consisted of 16 sessions of two hours. Measurements of glycosylated hemoglobin levels (HbA1c were performed before and after the intervention. Results: the educational program had positive effects because the results before the workshop showed that 61.5% of participants had poor-regular knowledge about the disease and its care, plus 84.6% of participants obtained percentages of HbA1c ≥ 6.5%. After the educational program, 100% of patients achieved a good level of knowledge and only 53.8% of the population reached an HbA1c level ≥ 6.5%. Conclusion: the educational program helps the patient cope in a better way their condition.

    Emissions of nitrous oxide (N{sub 2}O) were measured in agricultural lands used for farming wheat and maize during 1998 in the states of Hidalgo and Tlaxcala in Mexico. In an irrigated wheat field (El Tenhe, Hidalgo), an average flux of -10.85 {mu}g N{sub 2}O - N m{sup -}2 h{sup -}1 was obtained for the total cycle (155 days between December and May). There, high negative values were observed with Water Fill Porous Space (WFPS) close to 70%. The average flux of the complete cycle (269 days between March and December) in an irrigated maize field (El Progreso, Hidalgo) was 37.43 {mu}g N{sub 2}O - N m{sup -}2 h{sup -}1. In this case, more insignificant negative fluxes were found with WFPS close to 45% or less. These last results may have been influenced by the strong El Nino, which occurred in the middle of 1998. Twenty once percent of the measurements in the state of Hidalgo showed soil acting as a nitrous oxide sink. The samples from Tlaxcala showed that these fields acted as emitters. In the rain fed fields in the state of Tlaxcala, an average flux of 121 {mu}g N{sub 2}O - N m{sup -}2 h{sup -}1 was obtained for the wheat field. The farming season lasted 142 days, from July to December. In addition, for the maize field the averaged flux was 285.61 {mu}g N{sub 2}O - Nm{sup -}2h-1. The farming season lasted 246 days, from April to December.

Uno de ellos es Hidalgo: la historia jamás contada (Antonio Serrano, 2010, que ofrece una perspectiva totalmente inusual de la vida del héroe insurgente Miguel Hidalgo y Costilla. El presente artículo propone la tesis de que filmes como éste fueron financiados con el ánimo de (reapreciar símbolos históricos ante la crisis de identidad, valores y seguridad nacional que aqueja al país. En el caso de Hidalgo… fue un intento por reimpulsar a un personaje mítico que ayudase a enaltecer nuevamente lo idealizadamente mexicano.

    The greenhouse gases and black carbon emission inventory from IPCC key category Energy was accomplished for the Mezquital Valley, one of the most polluted regions in Mexico, as the Mexico City wastewater have been continuously used in agricultural irrigation for more than a hundred years. In addition, thermoelectric, refinery, cement and chemistry industries are concentrated in the southern part of the valley, near Mexico City. Several studies have reported air, soil, and water pollution data and its main sources for the region. Paradoxically, these sources contaminate the valley, but boosted its economic development. Nevertheless, no research has been done concerning GHG emissions, or climate change assessment. This paper reports inventories performed by the 1996 IPCC methodology for the baseline year 2005. Fuel consumption data were derived from priority sectors such as electricity generation, refineries, manufacturing & cement industries, transportation, and residential use. The total CO{sub 2} emission result was 13,894.9 Gg, which constituted three-quarters of Hidalgo statewide energy category. The principal CO{sub 2} sources were energy transformation (69%) and manufacturing (19%). Total black carbon emissions were estimated by a bottom-up method at 0.66 Gg. The principal contributor was on-road transportation (37%), followed by firewood residential consumption (26%) and cocked brick manufactures (22%). Non-CO{sub 2} gas emissions were also significant, particularly SO{sub 2} (255.9 Gg), which accounts for 80% of the whole Hidalgo State emissions. Results demonstrated the negative environmental impact on Mezquital Valley, caused by its role as a Megacity secondary fuel and electricity provider, as well as by the presence of several cement industries. - Highlights: • First GHG & black carbon inventory for Mezquital Valley: Mexico City energy supplier • Energy industries caused the largest CO{sub 2} and SO{sub 2} emissions from residual fuel oil. • Diesel

    As a part of the MILAGRO Field Campaign 2006, the influence of anthropogenic sources to metal air pollution in the Mezquital Valley, Hidalgo State, was explored by biomonitoring techniques. This valley is a major industrial- agriculture area located in central Mexico. An oil refinery, an electrical power plant, several cement plants with open-pit mines, as well as intensive wastewater-based agricultural areas, all within a 50 km radius, are some of the most important local sources of particulate air pollution. The concentrations of 25 metals and elements were determined by ICP-AES (EPA 610C method) for triplicate composite samples of the "ball moss" (T. recurvata ) collected at 50 sites. In addition, the ratios of two stable isotopes ((13C/12C and 15N/14N) were determined by continuous-flow isotope-ratio mass spectrometry in order to assess their potential as tracers for industrial emissions. Preliminary results showed high to very high average contents of several metals in the biomonitor compared to values from similar studies in other world regions, indicating a high degree of local air pollution. In contrast, most samples had Ag, As, Be, Se and Tl contents below detection levels (DL = 0.05 mg/kg of sample dry weight) indicating low levels of pollution by these metals. Metals such as Al, Ba, Ca, Fe, Li, Mo, Ni, Sr, Ti, V and Zn concentrated the most at the South portion of the valley, where the Tepeji-Tula-Apaxco industrial corridor is located. A transect parallel to the along-wind direction (N-S) showed a higher concentration of metals farther away from the sources relative to a cross-wind transect, which is consistent with the eolian transport of metal-enriched particles. Regional distribution maps of metals in the biomonitor showed that Al, Ba, Fe, Mo, Ni, Sr, Ti and V had higher levels at the industrial sampling sites; whereas K, Na and P were more abundant near to agriculture areas. Vanadium, a common element of crude oil, reflected better the influence from

    The lack of information about Chagas disease in Mexico, as well as the controversy concerning its importance, was the basis for the seroprevalence study of Trypanosoma cruzi in the National Seroepidemiology Survey (NSS). This information was representative of the national situation with regard to disease prevalences and other factors related to the nation's health. Unfortunately the NSS was not a very good information source for the study of trypanosomiasis americana, because its coverage in the disperse rural areas was poor. Nevertheless, the results of the NSS indicated that Chagas disease has an irregular distribution in Mexico with seroprevalences of 1.6, 0.5 and 0.2 for the different dilution levels used in the evaluation. The survey data showed Chagas disease to be less important than that mentioned by other authors. The NSS data confirmed the areas of disease transmission already reported and identified some new ones in Hidalgo, Chiapas and Veracruz. The survey also detected migratory workers with Chagas antibodies in Baja California border cities, a situation which indicates a risk for blood transfusion in areas of the country presumed to be free of the disease. Three quarters (74.5%) of the seropositive population were less than 39 years old. Moreover, the fact that children of less than four years were infected suggests that natural transmission is still very important in some areas. Although the seroprevalences were greater in the lower socio-economic groups, some persons of the higher socio-economic level were also affected. This situation may be explained by the fact that many of these persons own vacation homes in tropical areas.

    Full Text Available L os índices de productividad son esenciales en la planeación del manejo forestal sustentable. El índice de sitio es la metodología más utilizada en la clasificación de la calidad de las áreas forestales. Sin embargo, la mayoría de los macizos forestales y plantaciones no cuentan con tal información que apoye la planeación de las actividades silvícolas. Por ello, el objetivo fue estimar el índice de sitio de las plantaciones forestales de Pinus greggii Engelm., establecidas en la parte serrana del municipio de Metztitlán, Hidalgo. Los modelos de Schumacher, Chapman-Richards y Wei - bull se ajustaron con 233 observaciones de edad-altura provenientes de un análisis troncal. De acuerdo con el valor más bajo del cuadrado medio del error, el valor más alto de R 2 y la distribución de residua - les, se seleccionó el modelo de Schumacher para la construcción de la curva guía y el sistema de curvas anamórficas y polimórficas. Se establecieron cinco etiquetas de índice de sitio para las alturas 12, 14, 16, 18 y 20 m con calidades de estación V, IV, III, II y I, respectivamente. Se obtuvo buena estimación del crecimiento de la altura dominante en función de la edad, ya que considera todas las condiciones existentes dentro de las plantaciones.

    Full Text Available En este trabajo se aborda la problemática de la ficción y de la realidad intermediada por la operación paródica en El Ingenioso Hidalgo don Quijote de La Mancha de Miguel de Cervantes Saavedra. Se asedia el texto para ver cómo la parodia y la ironía son estrategias fundamentales para leer la concepción novelesca y cómo se permite al lector avieso adentrarse en la Poética cervantina, partiendo de los paratextos: prólogo, sonetos iniciales antes de adentrarnos en el cuerpo de la novela para luego calar en éste. En todo este cometido colaboran los narradores ficticios para "leer" la novela moderna que postula Cervantes en el libro e incluso se advierte que los distintos narradores dejan al descubierto la parodia y al mismo tiempo permiten un juego crítico-reflexivo en la materia textualThis paper examines the problematic of fiction and reality as mediated by parody in Cervantes’ Don Quijote de la Mancha. The approach to the text is meant to see how parody and irony become fundamental strategies to understand the novelistic concept, and how the perceptive reader is permitted to enter into the Cervantine poetic, starting from the paratexts: the Prologue; the opening sonnets, before getting into the core of the work discriminatingly. In all this procedure fictitious narrators collaborate in the reading of the modernistic novel which Cervantes postulated. It may also be noticed how the different narrators disclose the parodic while allowing a critical-reflexive play in the text

The physico-chemical characterization was realised by means of established determinations in NOM-021- RECNAT-2000 from the saturation extracts. The potential Z was moderate in these extracts and were correlated with physico-chemical parameters. From the calculated correlations it was possible to be determined that a correlation between physico-chemical properties of grounds like the pH and the potential Z exists (pZ. Also other correspondences between the values of pZ settle down, with the years of applications of the irrigation with black waters in these grounds. These studies provide the bases for later evaluations of probable affectations to the quality of grounds by the extensive use of irrigation with black waters.

    Heat fluxes between the atmosphere and the sea surface in the Gulf of Mexico are computed using COADS climatology, bulk formulae, radiation estimations from satellite, and a numerical model. 9 W m{sup -}2 is the estimated mean surface heat flux into the ocean, this is higher than previous studies due to different bulk formulae and data sources. The annual cycle has an amplitude of 168 W m{sup -}2. The contribution of each term in the heat equation is computed, analyzed and compared to previous studies. A numerical model with thermodynamics is used to study the relative importance of heat advection and entrainment on the sea surface temperature. The results indicate that the entrainment is important in the winter cooling of surface waters. When entrainment, which depends on the buoyancy loss and the wind induced turbulent kinetic energy, is not included, temperatures in winter stay higher than observations, with a root mean square (RMS) difference from observations of 1.5 C. Including entrainment and detainment the RMS decreases to 1.0 C.

    Over the years high cirrhosis mortality rates have been reported in Mexico City and in the surrounding states (Hidalgo, Tlaxcala, Puebla and the State of Mexico); on the contrary, well defined areas, such as the northern states, have shown a considerably lower mortality rate. This situation may indicate that some factors such as the pattern of alcoholic intake and other environmental characteristics could explain this striking difference. To determine the role of alcohol, the availability and consumption of alcohol at regional and state level were compared with cirrhosis mortality rates. A high and statistically significant correlation was found with pulque availability and consumption (r = 72-92%, p less than 0.01) in all periods of time under examination. On the contrary, a statistically significant negative association was observed with beer consumption and a positive, but not significant correlation, with distilled alcoholic beverages. Infectious hepatitis incidence, prevalence of exclusive use of native languages (as an indirect index of ethnic background) and nutritional deficiencies were also studied as possible risk factors. Nutritional deficiencies and the prevalence of exclusive use of náhuatl and otomí languages were positively correlated. These results can be useful to conduct further epidemiological studies still needed to determine the etiologic role of pulque consumption as well as of the other risk factors. Nonetheless, the current data stress the need to implement public health programs to reduce alcohol consumption, especially pulque, and to minimize the impact of these risk factors in high mortality areas.

    In spite of the measures that have taken for the decrease of the emitted pollution by mobile sources (''Today it doesn't Circulate'', implementation of catalysts in those exhaust pipes,...), the pollution in the Valley of Mexico area overcomes the limits fixed by Mexican standards several days each year. It is foreseen that for 2020 those emissions of pollutants will be increase considerably, as example we can mention to the sulfur oxides which will be increase a 48% with regard to 1998. The purpose of this work is of proposing a technique for the degradation of the sulfur dioxide (SO{sub 2}) that consists in introducing this gas to a plasma out of thermal equilibrium where its were formed key radicals (O, OH) for its degradation. The proposed reactor has the advantage of combining the kindness of the dielectric barrier discharge and of corona discharge, besides working to atmospheric pressure and having small dimensions. The first obtained results of the modelling of the degradation of the SO{sub 2} in plasma as well as those experimentally obtained are presented. (Author)

    Chemical equilibrium of formation waters from seven oil wells of the Activo Luna field (Tabasco, Mexico) was modelled. Saturation indices of characteristic hydrothermal minerals were calculated at ambient and reservoir conditions in order to predict scaling potential of deep and surface installations. The salinity of waters was found to be in the range from 43,000 (well Escuintle 2) to 250,000 (well Lune 3B) mg/kg as total dissolved solids. The water samples were classified as sodium-chioride type. Ionic strength for the solutions was found to be between 0.75 and 6.5. Activity coefficients were estimated by virial (Pitzer equations) methods using the GEOCHEMIST WORKENCH (GWB) software. Minerals such as anhydrite, halite, alunite, fluorite and barite were found to be supersaturated at reservoir conditions. A solid scale sample obtained from well Luna-3B was analysed. Analysis indicate the presence of calcite, anhydrite, fluorite and sphalerite which suggest the occurrence of temperatures of at least 180 Celcius degrees with acidic conditions and high chemical corrosion potential.

    Full Text Available Mycetoma is a chronic granulomatous disease. It is classified into eumycetoma caused by fungi and actinomycetoma due to filamentous actinomycetes. Mycetoma can be found in geographic areas in close proximity to the Tropic of Cancer. Mexico is one of the countries in which this disease is highly endemic. In this retrospective study we report epidemiologic, clinical and microbiologic data of mycetoma observed in the General Hospital of Mexico in a 33 year-period (1980 to 2013. A total of 482 cases were included which were clinical and microbiology confirmed. Four hundred and forty four cases (92.11% were actinomycetomas and 38 cases (7.88% were eumycetomas. Most patients were agricultural workers; there was a male predominance with a sex ratio of 3:1. The mean age was 34.5 years old (most ranged from 21 to 40 years. The main affected localization was lower and upper limbs (70.74% and 14.52% respectively. Most of the patients came from humid tropical areas (Morelos, Guerrero and Hidalgo were the regions commonly reported. The main clinical presentation was as tumor-like soft tissue swelling with draining sinuses (97.1%. Grains were observed in all the cases. The principal causative agents for actinomycetoma were: Nocardia brasiliensis (78.21% and Actinomadura madurae (8.7%; meanwhile, for eumycetomas: Madurella mycetomatis and Scedosporium boydii (synonym: Pseudallescheria boydii were identified. This is a single-center, with long-follow up, cross-sectional study that allows determining the prevalence and characteristics of mycetoma in different regions of Mexico.

    All the pollutants that are generated so much of anthropogenic activities as natural cause effects to the health, and of course its increase the atmospheric pollution. Today in day for the great advance of the technology other pollutants are even generated but noxious to the human being's health, such it is the case of the particles, which are also called particulate matter airborne (MPA). This has motivated, to establish control measures leaning in collection strategies and certified analysis techniques, accurate and reliable. In the National Institute of Nuclear Research (ININ) they have been carried out studies on particulate matter airborne. In 1991 it was installed, calibrated and validated the nuclear technique of atomic origin based on proton beams known as PIXE. The characterization of the (MPA) it is carried out applying this technique and the collection by means of Dichotomous collectors (SFU). The thesis work that is presented next, includes the topic of the atmospheric pollution by particulate matter airborne (MPA) in a mining region, inside the Hidalgo State. The study was carried out during the 1998 winter season, only embracing the whole month of March in alternate days giving a total of 112 samples. Two sites that are highly active in the mining were studied, these are: the Real del Monte town and the Hidalgo state capital: Pachuca. Four samples per day were collected beginning to the 7:00 am--7:00 pm (daytime period) and concluding to the 7:00 pm -7:00 am (nocturne period). The characterization of its elementary content is carried out using the X-ray emission induced by particles technique (PIXE) that is a nuclear technique able to analyze 23 chemical elements beginning from the Al to the Pb, it requires of a very small sample quantity, it is very sensitive and it is not destructive. This characterization one carries out so much for fraction PM 2.5 (fine) like as PM 10 (thick) in both sites, also it was analyzed the temporary variation that the

    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.

    Massive groundwater extraction is very common in Mexico and is well known to result in land subsidence. However, most surveys dedicated to land subsidence focus on one single city, mainly Mexico City, and thus fail to provide a comprehensive picture of the problem. Here we use a space-based radar remote sensing technique, known as Interferometric Synthetic Aperture Radar (InSAR) to detect land subsidence in the entire central Mexico area. We used data from the Japanese satellite ALOS, processed over 600 SAR images acquired between 2007-2011 and produced over 3000 interferograms to cover and area of 200,000 km2 in central Mexico. We identify land subsidence in twenty-one areas, including seventeen cities, namely from east to west, Puebla, Mexico city, Toluca de Lerdo, Queretaro, San Luis de la Paz, south of San Luis de la Paz, Celaya, south of Villa de Reyes, San Luis Potosi, west of Villa de Arista, Morelia, Salamanca, Irapuato, Silao, Leon, Aguascalientes, north of Aguascalientes, Zamora de Hidalgo, Guadalajara, Ahuacatlan, and Tepic. Subsidence rates of 30 cm/yr are observed in Mexico City, while in the other locations typical rates of 5-10 cm/yr are noticed. Regional surveys of this type are necessary for the development of hazard mitigation plans and efficient use of ground-based monitoring. We additionally correlate subsidence with land use, surface geology, and faults distribution and suggest that groundwater extraction for agricultural, urban, and industrial uses are the main causes of land subsidence. We also reveal that the limits of the subsiding areas often correlate with existing faults, motion on these faults being driven by water extraction rather than by tectonic activity. In all the subsiding locations we observe high ground velocity gradients emphasizing the significant risks associated with land subsidence in central Mexico. Averaged 2007-2011 ground velocity map from ALOS InSAR time-series in central Mexico, revealing land subsidence in 21

    La primera semana de septiembre de 2013, el Sistema Nacional de Vigilancia Epidemiológica identificó dos casos de cólera en Ciudad de México. Los cultivos de ambas muestras se confirmaron como Vibrio cholerae serogrupo O1, serotipo Ogawa, biotipo El Tor. Los análisis iniciales por electroforesis por campos pulsados y por reacción en cadena de la polimerasa indicaron que ambas cepas eran similares, pero diferentes de las previamente reportadas en México. La semana siguiente se identificaron cuatro casos más en una comunidad del Estado de Hidalgo, ubicada a 121 kilómetros al noreste de Ciudad de México. Posteriormente se inició un brote de cólera en la región de La Huasteca. Los análisis genómicos de cuatro cepas obtenidas en este estudio confirmaron la presencia de las islas de patogenicidad VPI -1 y VPI-2, VSP-1 y VSP-2, y del elemento integrador SXT. La estructura genómica de los cuatro aislamientos fue similar a la de V. cholerae cepa 2010 EL-1786, identificada durante la epidemia en Haití en 2010. Este estudio pone de manifiesto que la epidemiología molecular es una herramienta muy poderosa para vigilar, prevenir y controlar enfermedades de importancia en salud pública en México.

    tecnologia, se ha visto limitada por factores tales como el elevado costo de los distintos componentes que conforman una celda de combustible. Por ejemplo, el platino empleado por excelencia como el mejor catalizador para llevar a cabo la reaccion quimica entre hidrogeno y oxigeno, responsable de la produccion de energia electrica. En la busqueda de la optimizacion o sustitucion del platino, es importante contar con una metodologia que permita realizar un diagnostico in situ del estado de dicho catalizador. Este diagnostico involucra aspectos tales como la determinacion de los sitios activos y la carga y la degradacion que el catalizador puede ir sufriendo durante el funcionamiento de la celda. El presente trabajo consiste en el desarrollo de un modelo matematico que alimentado con las constantes de velocidad y los fenomenos involucrados en la reaccion de la evolucion del hidrogeno, produce como datos de salida, las curvas de polarizacion (E vs I) y de espectroscopia de impedancia electroquimica para dicha reaccion. Se considero para la modelacion, al Pt monocristalino preferenciado en las direcciones (111) y (100) como catalizador y usando diversos acidos como electrolitos.

    Full Text Available Triatoma mexicana was described by Herrich-Schaeffer in 1848. In 1940, a male specimen was found in Hidalgo. In 1970, this species was recorded in the state of Queretaro. Later, it was registered in Guanajuato and San Luis Potosi. In the present paper we performed an investigation in 545 dwellings from three counties in the state of Guanajuato, Mexico, from March 2003 to May 2004. The search and capture of triatomines were seasonally performed indoors and outdoors. Entomological indexes were calculated. The risk and no risk relations between triatomine presence and housing construction materials were analyzed. Fourteen triatomines were collected indoors and 151 outdoors. The vectors were collected in houses built with either risky and non-risky materials. Adults go indoors but do not settle there, hence, no relationship was found between the building materials and infestation of houses. Conventional interventions like house improvement or insecticide spraying are not efficient for the control of T. mexicana, because its developmental cycle is accomplished outdoors in the area surrounding the houses.

    Full Text Available Spatial and temporal variation in interactions between hummingbirds and plants have often been examined, and hummingbirds and insects are known to indirectly interact in networks of nectar plants. In a highland temperate forest in Hidalgo, Mexico some oak trees were heavily infested by honeydew-producing insects (family Margarodidae, tribe Xylococcini, genus Strigmacoccus and the honeydew was consumed by hummingbirds. Here using survival analysis we investigate how the honeydew produced by dense populations of these margarodids is temporally and spatially partitioned by hummingbirds. We also measured the availability and quality of honeydew exudates, and then we recorded the time until a bird visited and used such resources. Four hummingbird species consumed this resource (Atthis eloisa, Hylocharis leucotis, Colibri thalassinus and Eugenes fulgens. Data from 294 hours of observation on seven focal trees suggested temporal and spatial segregation among visiting birds according to body size and territorial behavior during the most honeydew-limited time. Hummingbird species differed in the daily times they foraged, as well as in the location where honeydew-producing insects were visited on the trees. Temporal and spatial segregation among hummingbird species is interpreted as an adaptation to reduce the risk of aggressive encounters. This may facilitate multispecies coexistence and allow these birds to exploit honeydew more effectively [Current Zoology 57 (1: 56–62, 2011].

    In September 2013, two cases of cholera were reported in Mexico; 1 week later, a new outbreak was reported in the Huasteca region of Hidalgo. Upon the determination that the diagnostic and therapeutic interventions implemented by health personnel overlooked predefined procedures, the National Institute of Public Health, in coordination with the Ministry of Health, immediately designed the massive open online course "Proper cholera containment and management measures" to strengthen and standardize basic prevention and control practices. During the first 5 months, 35,968 participants from across the country finished the course: medical and nursing personnel, health promoters, and hospital staff. To understand the magnitude of the data, an analysis was performed to calculate the MOOC coverage, and multiple linear regression models were generated to relate the score earned in the course to the characteristics of the participants. In addition, a qualitative analysis was performed to identify the dissemination of information, technological barriers, and feedback on course design. A total of 17% of participants were from the state where the outbreak originated, and 33.5% were from its neighboring states. This study shows that the need for information is greater when an emergency occurs, and the involvement of the authorities increased the extent of the training response. A MOOC can be a useful training strategy to prepare personnel for emergency situations.

    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.

    Full Text Available El conocimiento de las plantas medicinales por los otomíes (hñähñü de Nicolás Flores, Hidalgo se ha mantenido a través de las generaciones. La influencia de la medicina alópata está restringida principalmente a la prevención de enfermedades como poliomielitis, sarampión, viruela y paludismo. La medicina tradicional es más viable ante las condiciones socioeconómicas, fisiográficas y culturales en esta región. El objetivo de este estudio fue identificar las especies de plantas que utilizan los hñähñü con fines medicinales, el tipo de enfermedades que se tratan y la afinidad geográfica de las mismas. El trabajo de campo consistió en la realización de entrevistas abiertas a los pobladores del municipio y en la colecta de ejemplares en diferentes unidades "etnoecológicas". Se reporta el uso medicinal de 112 especies en el tratamiento de afecciones como susto, dolor de estómago, dolor del riñón, diarrea, fiebre, mal de ojo, entre otras. Aunque la mayoría de los habitantes conoce el uso medicinal de algunas plantas, los ancianos son más cultos, en la sabiduría hñähñü, como la de otras etnias de México, el pensamiento mágico-religioso forma parte de su cosmovisión y consideran la dualidad frío-caliente para el tratamiento. La gama de enfermedades que se presume curan las plantas registradas es muy amplio, desde la gripe hasta el cáncer. El 75 % de las especies utilizadas por esta etnia son nativas del Continente Americano, principalmente de México y Centroamérica (39 %, lo que sugiere que el acervo botánico básico tradicional hñähñü aún es vigente.

Se encontraron 26 familias de macroinvertebrados, con la máxima riqueza en agosto. El análisis de similitud de Jaccard diferenció los sitios litorales por su mayor riqueza de familias de la zona limnética, mismos que presentan diferencias en la composición de macrófitas. El estudio revela que la Laguna de Tecocomulco tiene variaciones espaciales y temporales relacionadas tanto con factores ambientales como bióticos con la presencia de grupos dominantes. En ese sentido, y considerando su diversidad de macroinvertebrados, la Laguna de Tecocomulco debe ser sujeta a un plan de conservación y manejo.

  9. Mexico's nuclear paradox

    International Nuclear Information System (INIS)

    Redclift, M.

    1989-01-01

    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)

    In Mexico, published studies relating to the occurrence of Hg in the environment are limited. Among the main sources of Hg in Mexico are mining and refining of Auand Hg, chloralkali plants, Cu smelting, residential combustion of wood, carbo electric plants, and oil refineries. Hg levels are highly variable in the atmospheric compartment because of the atmospheric dynamics and ongoing metal exchange with the terrestrial surface. In atmospheric studies, Hg levels are usually reported as total gaseous Hg (TGM). In Mexico, TGM values ranged from 1.32 ng m-3 in Hidalgo state (a rural agricultural area) to 71.82 ng m-3 in Zacatecas state (an area where brick manufacturers use mining wastes as a raw material).Published information on mercury levels in the coastal environment comprise 21 studies, representing 21 areas, in which sediments constituted the substrate that was analyzed for Hg. In addition, water samples were analyzed for Hg in nine studies.Few studies exist on Hg levels in the Caribbean and in the southwest of the country where tourism is rapidly increasing. Hence, there is a need for establishing baseline levels of mercury in these increasingly visited areas. In regions where studies have been undertaken, Hg levels in sediments were highly variable. Variations in Hg sediment levels mainly result from geological factors and the varying degree of anthropogenic impacts in the studied areas. In areas that still have pristine or nearly pristine environments (e.g., coast, Baja California, Todos Santos Bay, and La Paz lagoon), sediment Hg levels ranged from Mexico, it is clear that Hg fluxes to sediments have increased from2- to 15-fold in recent years. Since the 1940s, historical increases of Hg fluxes have resulted from higher agricultural waste releases and exhaust from the thermo electric plants. The levels of Hg in water reveal a moderate to elevated contamination of some Mexican coastal sites. In Urias lagoon (NW Mexico), moderate to high levels were found in

    Full Text Available Over the last thirty-five years, Mexico has maintained a trade liberalization policy which has depressed food production and has reconstructed the structure of the agri-food sector; this has generated a higher food dependence and insecurity. In order to face this structural change, new organizational and socio-productive dynamics have emerged in communities, which take into consideration food diversity, heritage and cultural conditions of rural areas. In this paper, we use the theoretical approach of Localized Agrifood Systems (LAFS and the operative concepts of governance and social innovation to analyze and understand the efforts that at the base of society are created to grant development of productive systems. Therefore, we present the results of an investigation based on the exploration of two LAFS cases; in these cases, different strategies to achieve development have been established: the elaboration of artisanal cheese in the state of Hidalgo, and the production of rice in the state of Morelos, Mexico. Research results show the importance of concepts such as Social Innovation (SI and Governance within the framework of localized agri-food systems in rural studies, this, in order to identify the needs and potentials of family farming and producer’s groups inside the new contexts generated by globalization and market liberation process.

    The state of Hidalgo, Mexico presents an important environmental problem that manifests itself in different ways. To identify the sources, types and the magnitude of pollutants, an inventory of sources of industrial and domestic pollution for air, water and soil in ten municipalities of the Huasteca Region of the state was carried out using the technique of Rapid Assessment of Sources of Environmental Pollution and the results are reported in this paper. A total of combined pollutants emitted was 116 978.95 tons/year. Gasoline vehicles contributed 11 039 tons/year of air pollutants and diesel vehicles 1521 tons/year. For water, industrial sources contributed 22 496 tons/year and domestic effluents 15 776 tons/year. Soil pollution was a result of industrial solid waste, 4025 tons/year, and municipal solid waste, 62 121 tons/year. By municipality, Huejutla de Reyes is the most polluted in air, water and soil, with 53 % of the regional total. These results were evaluated in relation to environmental quality of each medium based on the Mexican regulations; these levels are above permissible limits for water and soil. A database with relevant information was prepared as a support for efficient management of pollutant emissions, provide base mark data for complementary studies, and to promote the future conservation of environmental quality and the biological richness of the area.

    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.

    The article is aimed at reporting the characteristics of the population detected at State Prosecutors' Offices including the two such offices that existed in the city selected for the study, one located in a general hospital for the inspection of violence-related cases (n = 156); and the second in the facility where all detainees are taken when arrested (n = 129), and where victims can file a complaint (n = 186). A household survey undertaken among the population 18 to 65 years of age (n = 887) was used as a group of reference. Both studies were undertaken in Pachuca City, the capital of Hidalgo, located 100 km from Mexico City during the second half of 1996. Face-to-face questionnaires were used to obtain sociodemographic data, drug use and drinking patterns, depressive symptomatology, and family violence. Discriminant and logistic regression analysis were undertaken. The age group from 18 to 24 displayed the highest number of legal complaints and arrests (OR = 1.773). The likelihood for appearing at a State Prosecutor's Office was higher for those living in an atmosphere of threats and injuries within the family (OR = 19) and for those that reported alcohol consumption on the day of the event (OR = 14). Extremely high rates of family violence were obtained in this sample, increasing the likelihood of arriving at the Prosecutor's Office either because arrested or for being a victim. Results confirm the relationship between alcohol use, depression, and violence, reinforcing the need to prevent alcohol abuse, especially among youth.

    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.

    Untreated wastewater from the Mexico City basin has been used for decades to irrigate cropland in the Mezquital Valley, State of Hidalgo, Mexico. Excess irrigation water recharges the near-surface aquifer that is used as a domestic water supply source. We assessed the groundwater quality of three key groundwater sources of domestic water by analyzing for 24 trace metals, 67 target base/neutral/acid (BNA) organic compounds, nontarget BNA organics, 23 chlorinated pesticides, 20 polychlorinated biphenyls, and nitrate, as well as microbiological contaminants--coliforms, Vibrio cholerae, and Salmonella. Study participants answered a questionnaire that estimated ingestion and dermal exposure to groundwater; 10% of the sample reported frequent diarrhea and 9% reported persistent skin irritations. Detection of V. cholerae non-01 in surface waters at all sites suggested a potential risk (surrogate indicator present) of diarrheal disease for canal and river bathers by accidental ingestion, as well as potential Vibrio contamination of near-surface groundwater and potential cholera risk, magnified by lapses in disinfection. High total coliform levels in surface water and lower levels in groundwater at all sites indicated fecal contamination and a potential risk of gastrointestinal disease in populations exposed to inadequately disinfected groundwater. Using chemical criteria, no significant risk from ingestion or dermal contact was identified at the method detection limits at any site, except from nitrate exposure: infants and young children are at risk from methemoglobinemia at all sites. Results suggest that pathogen risk interventions are a priority, whereas nitrate risk needs further characterization to determine if formal treatment is needed. The risks exist inside and outside the irrigation district. The method was highly cost-effective.

    The Big Bend Regional Aerosol and Visibility Observational (BRAVO) Study was commissioned to investigate the sources of haze at Big Bend National Park in southwest Texas. The modeling domain of the BRAVO Study includes most of the continental United States and Mexico. The BRAVO emissions inventory was constructed from the 1999 National Emission Inventory for the United States, modified to include finer-resolution data for Texas and 13 U.S. states in close proximity. The first regional-scale Mexican emissions inventory designed for air-quality modeling applications was developed for 10 northern Mexican states, the Tula Industrial Park in the state of Hidalgo, and the Popocatépetl volcano in the state of Puebla. Emissions data were compiled from numerous sources, including the U.S. Environmental Protection Agency (EPA), the Texas Natural Resources Conservation Commission (now Texas Commission on Environmental Quality), the Eastern Research Group, the Minerals Management Service, the Instituto Nacional de Ecología, and the Instituto Nacional de Estadistica Geografía y Informática. The inventory includes emissions for CO, nitrogen oxides, sulfur dioxide, volatile organic compounds (VOCs), ammonia, particulate matter (PM) < 10 microm in aerodynamic diameter, and PM < 2.5 microm in aerodynamic diameter. Wind-blown dust and biomass burning were not included in the inventory, although high concentrations of dust and organic PM attributed to biomass burning have been observed at Big Bend National Park. The SMOKE modeling system was used to generate gridded emissions fields for use with the Regional Modeling System for Aerosols and Deposition (REMSAD) and the Community Multiscale Air Quality model modified with the Model of Aerosol Dynamics, Reaction, Ionization and Dissolution (CMAQ-MADRID). The compilation of the inventory, supporting model input data, and issues encountered during the development of the inventory are documented. A comparison of the BRAVO emissions

    To characterize intimate partner abuse and identify the main factors associated with violence in pregnancy in four highly deprived States in Mexico. The data were taken from the National Survey on Violence against Women 2003 (ENVIM per its abbreviation in Spanish). Based on it a cross-sectional study was conducted on 1 949 women between 15 and 50 years of age, who were once pregnant and who utilized primary and secondary health care services from the Ministry of Health, Mexican Institute of Social Security, and the Institute for Social Security and Services for State Workers in Guerrero, Hidalgo, Oaxaca and Chiapas states, between November 2002 and March 2003. Logistic regression was used to assess the association between independent variables and violence during pregnancy. 250 women (13%) suffered a type of violence (physical, psychological, sexual or economical) during any of their pregnancies. Of these women 76 (30.40%) were battered on their abdomen. In most of these cases (91.39%) the husband was the aggressor. The variables significantly associated with violence in pregnancy were: woman's illiteracy (OR 2.2; CI 95:% .1,4.4); history of violence in childhood (OR 3.2; CI 95% 1.9, 5.4) as well as sexual abuse in her childhood (OR 2.4, CI 95% 1.3, 4.4) and her partner's daily alcohol consumption (OR 6.5; CI 95% 3.3, 12.9). The results show that violence during pregnancy is a regular event in the impoverished context and that its expression is more severe. These results point to the importance of continued study of the problem of violence against pregnant women in Mexico and the importance of identifying battered women in prenatal care.

    1995-01-01

    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

    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

    1995-03-01

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

    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.

    Full Text Available At present in Mexico, the renewable energy has become more important due to the great dependence of the country for fossil fuels. Within the several applications of renewable energy, there are the geothermal applications for the air conditioning of spaces. This technology employs heat pumps that interexchange heat with the ground. This technology is relatively young in Mexico, leaving a large field for study and application throughout the country. In this way, to calculate the correct sizing of geothermal heat exchangers, it is necessary to calculate the thermal loads of the complex in which this technology of geothermal heat pumps using vertical heat exchangers type U will be installed, to perform the calculation of thermal loads Autodesk Revit® software was used, with which was possible to make a virtual model in detail of the botanical center that is located in Morelia, Michoacán, Mexico and belongs to the Universidad Michoacana de San Nicolás de Hidalgo (UMNSH. This study shows the results of the analysis of the installations and determination of the thermal loads of the complex due to this type of infrastructure. By obtaining the values of the thermal loads, the dimensioning of the heat exchanger was archived, which will have to be installed to cover the thermal requirement of this system and his installation, in addition to the selection of the heat pump. This complex of 2 levels, where, on the first floor there are cubicles and laboratories and on the second floor, several common areas. The design was developed in detail in Autodesk Revit 2015. After obtaining the thermal loads, the GLHEPro software was used for dimensioning the Vertical heat exchangers with the number and depth of the exchangers was obtained. the GLD 2014 software was used for dimensioning the Horizontal heat exchangers with the number and depth of the exchangers was obtained.

    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)

    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.

    Since January this year, a mobile atomic energy exhibition has been touring the principal cities of Mexico. In organizing this exhibition, the National Nuclear Energy Commission of Mexico was assisted by the International Atomic Energy Agency which has placed its second mobile radioisotope laboratory at the disposal of the Mexican authorities. In many States of the Republic, the visit of the mobile laboratory has given a powerful impetus to atomic training and research. Universities have made use of the laboratory for the training of young scientists in the basic isotope techniques. As a sequel to the work initiated with its aid, some universities are planning to start regular training courses in this field. The laboratory, which is a gift to the Agency from the United States, has been put to its first assignment in Mexico. It will shortly be sent to Argentina for a period of six months for use in training courses. IAEA's first mobile radioisotope unit, also donated by the United States, has been used for training purposes in Austria, the Federal Republic of Germany, Greece and Yugoslavia, and has now been sent to the Far East

    1990-12-01

    Research indicates that in-school adolescents in Mexico have their first sexual contact at the average age of 15.5 years. 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.

    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.

En este sentido, se describe el funcionamiento organizativo y el papel de los liderazgos por medio de un estudio de caso de una organización cuya actividad fundamental es la producción de nopal orgánico en la localidad de El Rincón, ubicada en el estado de Hidalgo, México. Metodología: tipo participativa. Consistió en visitas a campo, entrevistas semiestructuradas y no estructuradas, reuniones con productores y análisis FODA. Resultados: las organizaciones verticales y los liderazgos centralizados pueden impulsar un desarrollo del SIAL en un primer momento, pero son un obstáculo y una limitante en otros momentos que se distinguen por la desaparición, física o virtual, del liderazgo. Limitaciones: si bien se trata de un primer trabajo de acompañamiento para el desarrollo de un SIAL, es necesario recomponer previamente las relaciones de confianza entre la comunidad, dañadas por la inoperancia de la organización y de los actuales liderazgos. Conclusiones: adicionalmente al restablecimiento de relaciones de confianza, la organización debe ser más abierta para impulsar y valorizar el nopal como un producto diferenciado con un alto potencial para el desarrollo territorial.

    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

    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

    values and aminotransferases in obese and diabetic patients compared with normal subjects and overweight patients in our study, the USG did not show sensibility and specificity to detect Non alcoholic fatty liver disease (NAFLD). The results of this study show a lower frequency compared with the rest of the world, however it was higher in diabetic population than the frequency published by Bernal in Hidalgo, Mexico. The aminotransferases level resulted elevated in all patients with metabolic syndrome and NAFLD so we consider that elevated aminotransferases levels is the best predictor to suspect the presence of NAFLD. That is why it's very important to consider the possibility to avoid the progression to cirrhosis and hepatocarcinoma.

  19. Mexico Wind Resource Assessment Project

    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.

    Children 5 and younger are at risk for sustaining serious burn injuries. The causes of burns vary depending on demographic, cultural and socioeconomic variables. At this pediatric burn center we provided medical care to children from Mexico with severe injuries. The purpose of this study was to understand the impact of demographic distribution and modifiable risk factors of burns in young children to help guide prevention. A retrospective chart review was performed with children 5 and younger from Mexico who were injured from 2000-2013. The medical records of 447 acute patients were reviewed. Frequency counts and percentages were used to identify geographic distribution and calculate incidence of burns. Microsoft Powermap software was used to create a geographical map of Mexico based on types of burns. A binomial logistic regression was used to model the incidence of flame burns as opposed to scald burns in each state with relation to population density and poverty percentage. In all statistical tests, alpha=0.05 for a 95% level of confidence. Burns were primarily caused by flame and scald injuries. Admissions from flame injuries were mainly from explosions of propane tanks and gas lines and house fires. Flame injuries were predominantly from the states of Jalisco, Chihuahua, and Distrito Federal. Scalds were attributed to falling in large containers of hot water or food on the ground, and spills of hot liquids. Scald injuries were largely from the states of Oaxaca, Distrito Federal, and Hidalgo. The odds of a patient having flame burns were significantly associated with poverty percentage (ppoverty led to decrease in odds of a flame burn, but an increase in the odds of scald burns. Similarly, we found that increasing population density led to a decrease in the odds of a flame burn, but an increase in the odds of a scald burn. Burns in young children from Mexico who received medical care at this pediatric burn center were attributed to flame and scalds. Potential

  1. Texas-Mexico multimodal transportation: developments in Mexico

    Boske, Leigh B.

    1994-03-01

    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.

  2. Mexico City aerosol study

    1987-01-01

    A major task in the field of air pollution monitoring is the development of devices for determining the mass and composition of airborne particulate matter as a function of size - and time. The sample collection device must be designed giving consideration to the nature of the aerosol and to the effects of the aerosol on human health. It has been established that particles smaller than 3.5 μm in diameter can penetrate deeply into the human respiratory system, and that larger particles are trapped in the upper respiratory passages. For these reasons, it is desirable to use a dichotomous sampler to collect particles in two size ranges, rather than to collect total particulates on a single filter. The authors discuss a study in Mexico City using a dichotomous sampler

  3. Mexico introduces pentavalent vaccine.

    Combination vaccines have been introduced in Mexico. The national immunization program has incorporated the measles-mumps-rubella (MMR) vaccines in 1998, and the pentavalent vaccine in 1999. The two categories of antigen composition in combination vaccines are: 1) multiple different antigenic types of a single pathogen, such as the 23 valent pneumococcal polysaccharide vaccine, and 2) antigens from different pathogens causing different diseases, such as the DPT and MMR vaccines. Pentavalent vaccines are included in the second category. The vaccine protects against diphtheria, tetanus, pertussis, hepatitis B, and other diseases produced by Haemophilus influenzae type b (Hib). Combined diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenza type b (DTP-HB/Hib) vaccine has been distributed to 87% of Mexican children under 1 year of age. Over 800,000 doses of pentavalent vaccine have been administered.

  13. Uranium resources in New Mexico

    International Nuclear Information System (INIS)

    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

  16. Breast cancer genetic testing awareness, attitudes and intentions of Latinas living along the US-Mexico border: a qualitative study.

    2012-01-01

    Genetic testing for breast cancer may facilitate better-informed decisions regarding cancer prevention, risk reduction, more effective early detection, and better determination of risk for family members. Despite these potential benefits, significant portions of the US population-particularly Latinas-lack awareness of genetic testing for breast cancer susceptibility. Among women who are tested, less than 4% are Latina. To uncover reasons for Latinas' low participation, this study explores awareness, attitudes and behavioral intentions to undergo genetic testing among average-risk Latinas along the Texas-Mexico border. Eight focus groups were conducted with 58 Latinas aged 19-69 living in Hidalgo County, a largely Latino region of South Texas. Focus group discussions were digitally recorded, transcribed and analyzed using qualitative content analysis to assess, categorize and interpret them. Two experienced study team members analyzed transcripts to identify major concepts grouped into theme categories. Participants mostly had less than a high-school education (43%), spoke primarily Spanish (52%), were of Mexican-American origin (90%) and had a family income of $30,000 or less (75%). Focus groups found that most participants had positive attitudes and strong interest in genetic testing, yet lacked general awareness and knowledge about genetic testing, its risks, benefits, and limitations. Participants also identified several key cultural-based influencers, such as family, religious beliefs and fear of testing. The delivery of culturally adapted risk information is needed to increase and ensure Latinas' understanding of breast cancer genetic testing during their decision-making processes. Key Latino values-religiosity, importance of family and the influential role of health care providers in health decisions-should also be considered when designing interventions targeting this specific group. Further research is needed to identify effective ways to communicate

  17. Governability in Contemporary Mexico

    Directory of Open Access Journals (Sweden)

    Leonardo Curzio Gutiérrez

    1998-04-01

    Full Text Available Given the difficulties to establish a concept of governability and the frequent ideological usage of the term, it is much more operative to turn to the principle of governability, in the broad sense, which supports itself on five pillars: the political legitimacy of the government, the governmental efficiency to attend to the demands of society, the existence of shared social project, the agreement with the principle special interest groups, and international viability. The analysis of the structure and relevance of these five points during the long period of political transition that Mexico underwent between 1988 and 1997 shows how it was possible for this country to play off certain factors against each other in order to secure governability and safeguard against the consequences of any resultant imbalances. Between 1998-1993, the government of Salinas de Gotari based itself on the viability of a neoliberal project within an international context, and on this projectís attention to domestic demands as well as on the governmentís pact with elites. Institutional integration and legitimacy made up, then, for a process of discreet liberalization and the lack of democratic electoral commitment, which culminated in the PRI’s 1994 elections victory.The assassination of Colosia, though, and the appearance of the EZLN and the subsequent crisis surrounding the peso’s devaluation that accompanied Ernesto Zedilloís rise to power soon led to the collapse of those pillars of support. Crowning the process of the silenttransition were the elections of 1997, which makes it possible to say that in Mexico today there are now smooth elections, but that reform of the State is still unresolved —a subject that includes the reduction of the president’s competence. Seen in the short term, the most direct threats to Mexico’s governability will come as a result of the lack of attention to those demands of society’s underprivileged and the ill

  19. Mexico's critical choices

    International Nuclear Information System (INIS)

    Marcos, E.

    1990-01-01

    In Mexico, the 1982 fall in international oil prices shook the national conscience and pushed the Mexican people in search of a new national image and toward the choices they must make to attain that image. But, according to the author of this paper, the country as a whole has already made critical choices for overall strategy and there are reasons for optimism. In the current economic environment of growing domestic demand and enhanced international competitiveness, the author sees PEMEX (the Mexican national oil company) facing not only the challenge of responding to the rapid changes taking place in the Mexican economy, but also making a significant contribution toward the solid and stable growth of the country. The relevant question is how PEMEX will live up to these expectations. This paper describes several steps PEMEX has taken already or is preparing to take in order to meet this challenge, including: investment in the domestic petrochemical industry; entry into the Eurobond market; development of new methods of project financing

    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.

    This article describes the program activities of the Mexican National Commission on Human Rights (CNDH), which in 1994 created a program to address human rights issues of HIV-infected victims. The aim was to answer complaints of discrimination against HIV-infected persons and to modify confrontational attitudes of groups that feel infringed upon by the rights of HIV-infected persons. CNDH formed a task force of HIV/AIDS medical experts, which recommended actions for three types of discriminatory practices. Persons with HIV/AIDS (PWHA) who were confined in prison filed complaints about the lack of necessary medications or medical attention. The Official Mexican Norm for the Prevention and Control of HIV stipulates, in its Manual for the Attention of Complaints Regarding HIV/AIDS, protocols for treatment of PWHA. This manual was distributed to 31 State Human Rights Commissions in Mexico. CNDH implemented an outreach program to educate the public about HIV/AIDS, to offer training courses, and to publish written materials about discrimination against PWHA. The CNDH conducted conferences and training sessions for workers in the health services, where most violations of human rights take place. CNDH works closely with the National Board for the Prevention and Control of AIDS to assess clinical records, train staff handling complaints, and channel complaints that require CNDH intervention. CNDH conducts training workshops for nongovernmental organizations. CNDH is constrained by bureaucratic procedures that slow the process of resolving complaints and by the small CNDH staff responsible for handling the more complex cases. However, CNDH has successfully resolved a number of complaints and improved the prison conditions of PWHA.

Métodos El análisis costo-efectividad se realizó usando un árbol de decisión y se basó en los síntomas depresivos medidos con la escala CES-D. La efectividad de la intervención breve se evaluó comparando un grupo de mujeres indígenas que recibieron la intervención (n = 43 con otro similar sin intervención (n = 30. Los grupos se evaluaron antes, inmediatamente después de la intervención y a los 12 meses y se llevó a cabo en el Estado de Hidalgo, en México. El tratamiento farmacológico fue seleccionado como alternativa de comparación utilizando distintas estimaciones. Para evaluar el valor de la remisión de los síntomas de depresión se emplearon las razones de cos-to-efectividad y costo-efectividad incremental. Asimismo, se realizaron análisis de sensibilidad. Resultados La intervención breve resultó ser más efectiva que la farmacológica en la remisión de síntomas depresivos y su costo fue más bajo ($US 31,24 y $US 107,60, respectivamente. Solo si la intervención breve incrementara su costo por encima de 338% o si su efectividad fuera menor de 22,8% dejaría de ser costo-efectiva. Conclusiones La intervención breve de cinco pasos es una alternativa costo-efectiva con la cual se consiguen reducir significativamente los síntomas de depresión de las mujeres indígenas ocasionados por convivir con un consumidor excesivo de alcohol, así como una opción accesible para la atención de la salud mental en el primer nivel de atención.

    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.

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

  16. 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.

  17. Juvenile Justice in Mexico

    2014-08-01

    Full Text Available The first tribunal in Mexico was established in the central state of San Luis Potosi in 1926. The Law Regarding Social Prevention and Juvenile Delinquency for the Federal District and Mexican territories was promulgated in 1928. In 2005, Article 18 of the Mexican Constitution was modified to establish a comprehensive system (“Sistema Integral de justicia” in Spanish of justice for juveniles between 12 and 18 years old who had committed a crime punishable under criminal law. Its objective was to guarantee juveniles all the due process rights established for adults, in addition to the special ones recognized for minors. The constitutional reform also provides a framework that includes special tribunals as well as alternative justice options for juveniles. With these reforms, institutionalization of minors was to be considered an extreme measure applicable only to felonies and to juveniles older than 14. In 2006, all states within the Mexican federation enacted the “Law of justice for adolescents”. This system, at both the federal and state levels, formalizes a new global paradigm with regard to the triangular relationship between children, the State and the Law. It recognizes that children are also bearers of the inherent human rights recognized for all individuals, instead of simply objects in need of protection. However, despite formally aligning Mexican juvenile justice law with the Convention on the Rights of the Child (CRC, issues of actual substantive rights remained and new ones have appeared. For example, juveniles younger than 14 who have not committed a felony are released from institutions without any rehabilitation or treatment options, and alternative forms of justice were included without evaluating their possibilities of application or their conditions for success. In addition, the economic status of most juvenile detainees continues to be one of the most important determining factors in the administration of justice

  4. 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

    Full Text Available Abstract Background Food insecurity is a critical problem in the United States and throughout the world. There is little published data that provides insights regarding the extent and severity of food insecurity among the hard-to-reach Mexican-origin families who reside in the growing colonias along the Texas border with Mexico. Considering that culture, economics, and elements of the environment may increase the risk for food insecurity and adverse health outcomes, the purpose of this study was to examine the relation between household and community characteristics and food insecurity. Methods The study used data from the 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA. The data included 610 face-to-face interviews conducted in Spanish by promotoras (indigenous community health workers in forty-four randomly-identified colonias near the towns of Progreso and La Feria in Hidalgo and Cameron counties along the Texas border with Mexico. C-HCFRA included demographic characteristics, health characteristics, food access and mobility, food cost, federal and community food and nutrition assistance programs, perceived quality of the food environment, food security, eating behaviors, and alternative food sources. Results 78% of participants experienced food insecurity at the level of household, adult, or child. The most severe - child food insecurity was reported by 49% of all households and 61.8% of households with children. Increasing levels of food insecurity was associated with being born in Mexico, increasing household composition, decreasing household income, and employment. Participation in federal food assistance programs was associated with reduced severity of food insecurity. Greater distance to their food store and perceived quality of the community food environment increased the odds for food insecurity.

    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)

  15. Manufacturing real wages in Mexico

    Directory of Open Access Journals (Sweden)

    López V Antonia

    2006-01-01

    Full Text Available In this paper we analyse the recent evolution and determinants of real wages in Mexico?s manufacturing sector, using theories based on the assumption of imperfect competition both in the product and in the labour markets, especially wage-bargain theory, insider-outsider and mark-up models. We show evidence that the Mexican labour market does not behave as a traditional competitive market. The proposed explanation for this fact is that some workers benefit from advantages when compared with others, so that they can get a greater share of the proceedings of the productive process. Also, we find that changes in the degree of competition in the market for output influence the behaviour of real wages.

  16. History of nonnative Monk Parakeets in Mexico.

    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

    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.

    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)

    Torres-Jardón, R.*, Rosas-Pérez, I., Granada-Macías, L. M., Ruiz-Suárez, L. G. Centro de Ciencias de la Atmósfera, UNAM, México D. F. México * rtorres@unam.mx For many years, the vegetation of forest species such as Abies religiosa in natural parks located in the southwest mountains of Mexico City has attracted much attention since these parks have been experiencing a severe decline of unclear etiology. The high ozone levels in the area and the observed naked eye macroscopic, histological and cytological injuries on these species, strongly suggest an important contribution of tropospheric ozone to this deterioration process. Apart of historical short monitoring campaigns for measuring ozone levels in these mountains, it is known just a little is known about the present exposure levels at which the local vegetation is exposed. A continuous ozone analyzer has been in operation since 2011 at a high-elevation forest site (Parque Nacional Miguel Hidalgo, PNMH; 3110 m above mean sea level) located downwind of Mexico City Metropolitan Area (MCMA), in order to characterize the local ozone diel amplitude and its seasonal trend, as well as the influence of MCMA on the local O3 concentrations. Hourly average ozone data in PNMH shows that in general, the diel of ozone concentrations in the forest site has a statistical significant correlation with the pattern of ozone levels observed in several monitoring sites (smog receptor sites) within the MCMA, although the high elevation O3 levels are relatively lower than those in the urban area (around 2200 m above mean sea level). It is possible that a part of the oxidants in the air masses are removed by sink deposition processes during the air mass transport across the hills. The diel amplitude of ozone concentrations is small in the cold season, increasing as the seasons advance to June. As in the city, the highest ozone concentrations occur in April or May and the lowest levels during the rainy season, which extends from

    Major sulphur dioxide emissions in Mexico are due largely to fuel of oil refining and coal combustion. In Tula-Vito-Apasco industrial corridor (TVA) are located two important sources of SO/sub 2/: the 'Miguel Hidalgo' refinery and the 'Francisco Perez Rios' power plant. Due to from March 25 to April 22 of 2006 a major field campaign took place as part of a collaborative research program called MILAGRO. Data collected around the Industrial Complex were used to: a) evaluate the air quality to local and regional scale; b) study the structure of the atmospheric boundary layer (BL); and c) validate meteorological and dispersion models. In this study we presented the behaviour of daytime BL, and the results of meteorological and dispersion modelling for selected episodes of high sulfur dioxide (SO/sub 2/). The Regional Atmospheric Modeling System (RAMS) and the Hybrid and Particle Concentration Transport Model (HYPACT) were used to evaluate the impact of SO/sub 2/ emissions to regional scale. For modelling, we selected the days where higher mean daily levels of SO/sub 2 /surface concentrations were observed, these corresponded to March 31 and April 6. The results indicate that: The daytime BL in TVA, exhibited a normal behavior, a stable layer or thermal inversion close to surface was observed at 0800 LST (up to 80% of the cases), then the mixing height (MH) growths, with a growth rate of 313 m h-1 (between 0800 to 1200 LST). The most rapid MH growth happened between 1200 to 1500 LST;. The maximum MH was observed at 1500 LST (90% of the cases); the mean maximum MH was close to 2794 m AGL; Potential temperature and humidity profiles showed a normal behavior; High persistence in wind direction (> 0.6) close to surface up to 500 m AGL, was observed at 1500, and 1800 LST, at the same time, a low level jet, penetrating from the NE, with wind speed between 6 to 8 m s/sup -1/ was observed. Meteorological modelling was used to determine the circulation patterns in the region

    The alternative fuels are born with the goal of not damaging the environment; biodiesel, electricity, ethanol, hydrogen, methanol, natural gas, LP gas, are the main alternative fuels. However, the biodiesel and bioetanol are the only completely renewable ones, this makes them ideal to be developed in Mexico, since the agricultural sector could be fortified, the technological independence be favored, improve the conservation of the oil resources and by all means not to affect the environment. On the other hand, also efficient cultivation techniques should be developed to guarantee the economy of the process. [Spanish] Los combustibles alternativos nacen con la meta de no danar el medio ambiente; el biodiesel, electricidad, etanol, hidrogeno, metanol, gas natural, gas LP, son los principales combustibles alternativos.

    Four geothermal fields are currently operating in Mexico (Cerro Prieto, Los Azufres, Los Humeros and Las Tres Virgenes), with a total installed geothermal-electric capacity of 953 megawatts (MW). This means the country is located in third place, worldwide, just behind the USA and Philippines. Thirty-six power plants of several types (condensing, back pressure and binary cycle), between 1.5 and 110 MW, operate in the fields, fed by 197 wells with a combined production of 7,700 metric tons of steam per hour (t/h). These production wells have depths between 600 and 4,400 meters. Steam comes with 8,750 t/h of brine that is injected through 19 injection wells or treated in a solar evaporation pond of 14 km2 in Cerro Prieto. During 2003, steam produced in those fields equaled 67.5 million metric tons, and the power plants generated 6,282 gigawatt-hours (GWh), which represented 3.1% of the electric energy produced in Mexico. All the power plants and the geothermal fields are operated bye the public utility, the Comision Federal de Electricidad (Comision Federal de Electricidad (CFE)).

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

    2010-01-01

    The high price of fossil fuels and the environmental damage they cause have encouraged the development of renewable energy resources, especially wind power. This work discusses the potential of wind power in Mexico, using data collected every 10 min between 2000 and 2008 at 133 automatic weather stations around the country. The wind speed, the number of hours of wind useful for generating electricity and the potential electrical power that could be generated were estimated for each year via the modelling of a wind turbine employing a logistic curve. A linear correlation of 90.3% was seen between the mean annual wind speed and the mean annual number of hours of useful wind. Maps were constructed of the country showing mean annual wind speeds, useful hours of wind, and the electrical power that could be generated. The results show that Mexico has great wind power potential with practically the entire country enjoying more than 1700 h of useful wind per year and the potential to generate over 2000 kW of electrical power per year per wind turbine installed (except for the Chiapas's State). Indeed, with the exception of six states, over 5000 kW per year could be generated by each turbine. (author)

    World Health Organization cites among the main challenges of populational aging the dual disease burden: the greater risk of disability, and the need for care. In this sense, the most frequent chronic diseases during old age worldwide are high blood pressure, type 2 diabetes mellitus, cancer, arthritis, osteoporosis, depression, and dementia. Chronic disease-associated dependency represents an onerous sanitary and financial burden for the older adult, the family, and the health care system. Thus, it is necessary to propose community-level models for chronic disease prevention and control in old age. The aim of the present work is to show our experience in the development and implementation of a model for chronic disease prevention and control in old age at the community level under the active aging paradigm. A longitudinal study will be carried out in a sample of 400 elderly urban and rural-dwelling individuals residing in Hidalgo State, Mexico during five years. All participants will be enrolled in the model active aging. This establishes the formation of 40 gerontological promoters (GPs) from among the older adults themselves. The GPs function as mutual-help group coordinators (gerontological nuclei) and establish self-care and self-promotion actions for elderly well-being and social development. It will be conformed a big-net of social network of 40 mutual-help groups of ten elderly adults each one, in which self-care is a daily practice for chronic disease prevention and control, as well as for achieving maximal well-being and life quality in old age. Indicators of the model's impact will be (i) therapeutic adherence; (ii) the incidence of the main chronic diseases in old age; (iii) life expectancy without chronic diseases at 60 years of age; (iv) disability adjusted life years lost; (v) years of life lost due to premature mortality, and (vi) years lived with disability. We propose that the implementation of the model active aging framework will permits the

    As a result of population growth and increasing industrialization, air pollution in heavily populated urban areas is one of the central environmental problems of the century. As a part of the MILAGRO (Megacity Initiative: Local and Global Research Observations) study, Nuclepore filters were collected in two size ranges (PM10 and PM2.5) at 12 hour intervals at three location in Mexico during March, 2006. Sampling stations were located at the Instituto Mexicano del Petroleo (T0), at the Rancho La Bisnago in the State of Hidalgo (T2) and along the Gulf Coast in Tampico (Tam). Each filter was analyzed for mass concentration, aerosol scattering and absorption efficiencies. Mass concentrations at T0 ranged from 47 to 179 μg/m3 for PM10 with an average concentration of 96 μg/m3, and from 20 to 93 μg/m3 for PM2.5 with an average concentration of 41 μg/m3. Mass concentrations at T2 ranged from 12 to 154 μg/m3 for PM10 with an average concentration of 51 μg/m3, and from 7 to 50 μg/m3 for PM2.5 with an average concentration of 25 μg/m3. Mass concentrations at Tam ranged from 34 to 80 μg/m3 for PM10 with an average concentration of 52 μg/m3, and from 8 to 23 μg/m3 for PM2.5 with an average concentration of 13 μg/m3. While some of the extreme values are likely linked to local emissions, regional air pollution episodes also played important roles. Each of the sampling stations experienced a unique atmospheric condition. The site at T0 was influenced by urban air pollution and dust storms, the site at T2 was significantly less affected by air pollution but more affected by regional dust storms and local dust devils while Tam was influenced by air pollution, dust storms and the natural marine environment. The spectral mass absorption efficiency was measured from 350 to 2500 nm and shows large differences between the absorption properties of soil dust, black carbon, and organic aerosols. The strong spectral differences observed can be related to differences in

    In the state of Hidalgo, Mexico, is found the largest second deposit of Manganese (Mn) in Latin America. Various studies on the sources of emission, exposure, and the effects on the health of children and adults have been conducted utilizing an ecosystem approach. Given the findings of Mn levels in air and the neurocognitive effects, an Environmental Management Program (EMP) was designed and implemented with the purpose of reducing exposure to Mn of the population, including various actions for reducing Mn emissions into the atmosphere. To evaluate the impact of the EMP on the concentrations of Mn in air, as well as the modification of exposure to Mn in the blood and hair of adult residents of the communities intervened. A quasi-experimental study was conducted in five rural communities, in which Mn concentrations were evaluated in air and in blood in the years 2002 and 2007, pre-intervention, and in 2013, postintervention. In 2003, the concentration of hair Mn among the communities was evaluated. Measurements were carried out of Particulate Matter (PM) of >10 and 2.5μm (PM10 and PM2.5), and Mn in PM10 and PM2.5 were measured using proton-induced X-ray emissions (PIXE). The method of Difference in Differences (DID) was applied to estimate the impact of EMP on Mn concentrations in particulate matter via linear regression through multilevel models. To evaluate the effect of Mn concentrations in air over Mn concentrations in blood in both study periods in the mining communities per year (2002 and 2013), a linear regression model for each year was employed. We estimated that the EMP contributed to reducing the average daily concentrations of Mn in PM10 and PM2.5 by 92 and 85%, respectively. The adjusted model did not show an effect of Mn concentrations in air over Mn concentrations in blood in both study periods. The results suggest that the measures implemented to reduce Mn emissions in air exerted a significant impact on the reduction of inhaled exposure in adult

    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.

    The history of the electrical power sector in Mexico, the prominent role that government plays in the generation, transformation, distribution and supply of electrical power, and the implications of the North American Free Trade Agreement (NAFTA) for this sector were summarized. The slow pace of the Mexican electricity sector in achieving cost efficiency through pricing policy was criticized, and the issue of regulation versus deregulation of the electricity sector was examined in the context of NAFTA, emphasizing the contradiction between the idea of international trade and a highly regulated industry. Revisions of the original constitutional article to exclude electrical power generation from governmental control and to allow market mechanisms and competition to lower costs and increase efficiency was recommended.It was considered a pre-condition to a stable balance between competition and energy efficient environmentally friendly practices.

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

    In 1980 it was installed in Mexico, on the National Institute of Nuclear Research, an irradiator model J S-6500 of a canadian manufacture. Actually, this is the greatest plant in the Mexican Republic that offers a gamma irradiation process at commercial level to diverse industries. However, seeing that the demand for sterilize those products were not so much as the irradiation capacity it was opted by the incursion in other types of products. During 17 years had been irradiated a great variety of products grouped of the following form: dehydrated foods, disposable products for medical use, cosmetics, medicaments, various. Nowadays the capacity of the irradiator is saturated virtue of it is operated the 24 hours during the 365 days of the year and only its operation is suspended by the preventive and corrective maintenance. However, the fresh food market does not be attended since this irradiator was designed for doses greater than 10 kGy (1.0 Mrad)

    1989-01-01

    Fertility, health, and family planning are not independent factors, but rather involve a series of biological and social mechanisms in close interaction with one another. The impact that a high fertility rate has on health is reflected mainly in a rise in the rates of maternal and child mortality. Similarly, fertility has a greater negative effect upon the health of groups characterized by high reproductive risk, high parity, short intergenesic intervals, and unwanted pregnancies. On the other hand, family planning -and specifically the use of contraceptive methods-helps to achieve a lowering of the fertility rate and also has a positive effect on maternal-child health. This situation can be observed in the case of Mexico, where fertility rates and tendencies, as well as maternal and child mortality, have been reduced during the past decade.

    The author examines patterns of internal and international migration in western Mexico. "Drawing on data from different sources and statistics, the essay demonstrates the importance of both types of migration, the changes in endogenous and exogenous factors which have affected the life and the migratory patterns of the population of this region. The migratory circuit being a flow not only of persons, but of goods and capital as well, the cities, specifically that of Guadalajara, have a strategic importance. They fulfill various functions and have become the backbone of the migratory process: they serve as centers for attracting and 'hosting' internal migrants as well as places of origin for other migrants; jumping-off points for international migrants; and the milieu in which many returning migrants of rural origin settle."

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

    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

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

    The 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.

    2014-02-21

    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.

  9. Energy, environment and development in Mexico

    International Nuclear Information System (INIS)

    Lohmann, J.

    1990-01-01

    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

  10. 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

    2016-12-01

    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.

  8. Gulf of Mexico deep-water

    International Nuclear Information System (INIS)

    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

  9. Reform in Mexico: imports, exports and investments

    International Nuclear Information System (INIS)

    Estrada, J.

    1997-01-01

    Terms of the policy and regulatory reform for the natural gas sector in Mexico since 1993 were described, and major changes taking place in the structure, organization and operations of the sector since the introduction of reforms were reviewed. Consequences that the structural changes are likely to have on the long-term balance of natural gas supply and demand in Mexico, have been assessed. The goal of full open access by November of 1997 was reiterated. Reforms to the electric power industry also have been undertaken. As with natural gas, the objective is to eliminate the State monopoly and to allow private power producers to participate in the expansion of the sector's generating capacity. Public investment will be directed towards the improvement of transmission and distribution networks. Over time, independent power producers are expected to become the principal source of funds for the expansion of electric power availability in Mexico. 3 tabs., 29 figs

  10. 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.

  11. Human rights and conventionality control in Mexico

    2014-12-01

    Full Text Available The protection of human rights in Mexico has, de jure, suffered an important change in the last years, given a new judicial interpretation delivered by the National Supreme Court of Justice that allows the use of conventionality control, which means, that it allows federal and state judges to verify the conformity of domestic laws with those established in the Inter-American Convention of Human Rights. To what extent domestic actors are protecting human rights using this new legal tool called conventionality control? In this article I explore whom and how is conventionality control being used in Mexico. Using N-Vivo Software I reviewed concluded decisions delivered by intermediate level courts (Collegiate Circuit Courts in three Mexican states. The evidence points that conventionality control is a very useful tool especially to defenders, who appear in sentences claiming compliance with the commitments Mexico has acquired when this country ratified the Convention.

  12. Radon in soil concentration levels in Mexico

    International Nuclear Information System (INIS)

    Segovia, N.; Tamez, E.; Mena, M.

    1991-09-01

    Radon in soil surveys in Mexico have been carried out since 1974 both for uranium prospectus and to correlate mean values of the gas emanation with local telluric behaviour. The mapping includes the northern uranium mining region, the Mexican Neo volcanic 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 Mexican territory is presented. The lowest mean values have been found 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)

  13. Mexico On A Criminal Traffic Scenario

    Directory of Open Access Journals (Sweden)

    M. P. Moloeznik

    2017-01-01

    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.

    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.

    Valencia, Mauro E; Ramirez-Lopez, Erik; Ramos-Salas, Je; Bourges, Hector; Espinoza, Teresa

    2014-01-01

    Full text: Background. Body mass index (BMI) is an international standard to evaluate nutritional status but has the inability to distinguish fat mass from fat free mass, especially with regards to ethnicity. Mexico is the eight country in ethnic diversity in the world. The changes in fat mass and fat free mass offers the possibility to evaluate the effects of intervention programs in shorter periods. Objective. The purpose of the present study was to investigate the relationship between body composition and anthropometric characteristics of indigenous and mestizo Mexican children. Subject and Methods. A total of 1618 male and female indigenous (n = 498) and mestizo (n = 1120) children 7-9 years, were selected by stratified multiple stage cluster sampling. Indigenous groups and States were: Tarahumaras (Chihuahua), Mayos (Sonora), Nahuas (Puebla), Otomíes (Hidalgo), Tzotziles (Chiapas) and Mayas (Yucatan Peninsula). Mestizos form the same regions were included. Fat free mass and fat mass were obtained from a previously reported BIA cross validated equation using deuterium oxide dilution from 339 children from the same population, groups and regions. Results. The indigenous groups had 18.5 + 5.9 % fat compared to 23.5 + 8.4 in the mestizos (p<0.0001). Nahuas had the lowest % fat (p<0.0001) with 16.5 + 5.7, compared to Mayos, Tarahumaras and Mayas that had 18.6 + 6.2, 19.0 + 6.3 and 18.0 + 6.5 respectively. Mestizos form the Centre, North, and South had the highest levels of % body fat (p<0.001) with 25.4 + 7.7, 21.9 + 8.2, and 20.5 + 7.8, respectively. In indigenous children (n = 498) the 5th percentile (95% CI) corresponded to 9 (8,10) % body fat, while for Mestizos (n = 1120), the 5th percentile was 10 (9,11). Using this percentile, only one third of the children approximately of both groups would be classified as thin by WHO and IOTF classifications. Conclusion. Indigenous children had lower body fat than mestizos, however, the relationship of BMI to % body fat

  6. 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.

  8. Abortion legalization and childbearing in Mexico1

    In 2007 abortion was legalized in the Federal District of Mexico, making 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. In this paper, we examine metropolitan area differences in overall and parity-specific, as well as the age pattern of childbearing between 2000 and 2010 to more precisely isolate 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, though 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. PMID:27285423

    This paper explores poverty trends in Mexico during the 1990's using three different definitions of poverty. The paper then uses poverty convergence analysis to explore the pre-crisis (1992-1994), the crisis (1994-1996), and the recovery periods (1996-1998). Finally, the paper incorporates a regional analysis in order to examine these poverty effects in greater detail.

  15. Faulting in eastern New Mexico: Revision 1

    International Nuclear Information System (INIS)

    Murphy, P.J.

    1987-08-01

    This area in eastern New Mexico is being studied because of its proximity to a proposed high-level nuclear waste repository site in Deaf Smith County, Texas. Regional and local tectonics must be thoroughly understood in order to be able to predict future tectonic activities in the site region. Hydrogeologic studies indicate that ground-water recharge, for regional deep and shallow aquifer systems, occurs primarily within the study area. Regional, easterly ground-water flow may be significantly affected by the spacing, orientation, and character of faults identified in this report. The tectonic history of eastern New Mexico is developed from information from 660 exploratory wells. A history of recurrent tectonic movements is evident, beginning possibly in the late Precambrian and extending into the late Cenozoic. The nature of the evidence includes the lateral and vertical distribution and the lithology of these deposits. The results are presented mainly as isopach and structure contour maps and as structural cross sections. The Paleozoic tectonic history of eastern New Mexico is similar and related to the history of the Texas Panhandle. Differences occur primarily in the Mesozoic and Cenozoic histories; tectonic uplift persisted for longer periods and faults show evidence of repeated movements in eastern New Mexico. This is probably a result of the proximity of the area to the Laramide and Basin and Range deformational events. 442 refs., 35 figs

    2015-01-01

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

    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

    Full Text Available OBJECTIVE: To describe in a national sample 1 the mean total cholesterol (TC, HDL-cholesterol (HDLc and triglyceride (TG concentrations, 2 the prevalence of the most common lipid abnormalities and 3 the association between obesity and these conditions. MATERIAL AND METHODS: We analyzed the nationally representative, cross-sectional Me-xican Health Survey (2000. The final analytic sample used consisted of 2 351 individuals at fasting state. TC, HDLc and TG were determined. BMI was classified according to the WHO cut-off points. Sex-specific means and 95% confidence intervals (95%CI were calculated by age group for TC, HDLc and TG. The prevalence of: a hypercholesterolemia (HC, b hypoalphalipoproteinemia (HA, c hypertriglyceridemia (HT, d HT with HA and e HC with HT was calculated adjusting for age. Multivariate logistic regression models were estimated to analyze the association of obesity to the prevalence of dyslipidemias. RESULTS: The mean TC, HDLc, and TG concentrations were: 197.5 mg/dl (95% CI= 194.0, 201.1, 38.4 mg/dl (95% CI= 37.2, 39.5 and 181.7 mg/dl (95% CI= 172.7, 190.6, respectively. HC was present in 40.5% of the adult females (95% CI=35.5, 45.4 and 44.6 of the adult males (95% CI=37.7, 51.4; HA was the most prevalent form of dyslipidemia, present in 64.7% (95% CI=58.7, 70.8 and 61.4% (95% CI=54.4, 68.3 of females and males, respectively. Obesity increased ~1.4 times the probability ratio (PR of having HC among women and 1.9 among men. CONCLUSION: TC concentrations from our study in Mexico were similar to those found for Mexican-Americans and the prevalence of HC was slightly lower than the one reported in the US; however, it increased ~26% from 1988 to 2000. HA was the most frequent lipid abnormality followed by HT. Regions showed no significant differences, contrary to what has been previously reported.OBJETIVO: Describir en una muestra nacional las concentraciones de 1 colesterol total (CT, colesterol-HDL (cHDL y triglic

  4. REPRODUCTIVE SEASONALITY OF SHEEP IN MEXICO

    Jaime Arroyo

    2011-07-01

    Full Text Available In order to discuss and analyze the available information concerning the seasonal breeding behavior of sheep in Mexico, this review was conducted. We analyzed the neuroendocrine basis that modulate the annual reproductive cycle in sheep and then discussed the degree of reproductive seasonality in Creole sheep wool, breeds originating in high latitudes and hair sheep, mainly in Pelibuey ewes. The Creole sheep wool show continuous annual reproductive activity and short seasonal anestrous. The females of northern origin, express seasonal reproductive activity, similar to that observed in individuals geographically located at latitudes above 35º. Pelibuey sheep show variable annual reproductive behavior with reduced anestrus or lack thereof.  It is suggested that the neuroendocrine mechanisms regulating seasonal anestrus in ewes, are active in the sheep of northern origin that live in Mexico, in a manner contrary is not activated in Creole and hair sheep.

In practice, there has been a divorce between rhetoric and reality. The growth of GDP post-liberalisation has been only one-half that pre-liberalisation. This paper gives three explanations. Firstly, export growth has hardly changed. Secondly, there has been a sharp increase in the propensity to import (partly related to US direct foreign investment which has reduced the growth of GDP consistent with a sustainable balance of payments equilibrium on current account. Thirdly, liberalisation has been used as a substitute for a development strategy.

  7. Regulatory reform in Mexico's natural gas sector

    International Nuclear Information System (INIS)

    1996-01-01

    In recent years Mexico has implemented remarkable structural changes in its economy. However, until recently its large and key energy sector was largely unreformed. This is now changing. In 1995 the Mexican Government introduced legislative changes permitting private sector involvement in natural gas storage, transportation and distribution. Subsequent directives set up a detailed regulatory framework. These developments offer considerable promise, not only for natural gas sector development but also for growth in the closely linked electricity sector. This study analyses the changes which have taken place and the rationale for the regulatory framework which has been established. The study also contains recommendations to assist the Government of Mexico in effectively implementing its natural gas sector reforms and in maximizing the benefits to be realised through the new regulatory framework.

  8. Laguna Verde: the nuclear debate in Mexico

    Weinberg, Bill.

    1987-01-01

    Mexico in planning to start up its first nuclear power station at Laguna Verde in the state of Veracruz (1988). The history of the plant is traced; it should have been finished by 1974. Both the fuel and the technology have been imported from the United States for Laguna Verde. The design, a Mark II Boiling Water Reactor, is controversial and there are doubts as to its safety. Opposition to the plant on safety and environmental grounds has grown. In April 1987 a 'Chernobyl anniversary' demonstration had 10,000 protesters and opponents of the plant are becoming more militant. The main opposition is from environmental and 'Green' groups but also includes intellectuals. However, politically, Mexico would find it embarrassing to cancel the plant and also it wants to be seen as a 'First World' rather than a 'Third World' country. (U.K.)

    A new Accelerator Mass Spectrometry system has been installed at the Institute of Physics of the National Autonomous University of Mexico (UNAM). A sample preparation chemistry laboratory equipped with computer controlled graphitization equipment (AGEIII) has also been established. Together both facilities constitute the LEMA (Laboratorio de Espectrometría de Masas con Aceleradores) first of its kind in Mexico. High sensitivity characterization of the concentration in a sample of 14C as well as 10Be, 26Al, 129I and Pu are now possible. Since the demand for 14C dating is far more abundant, a data analysis program was developed in the cross-platform programming language Python in order to calculate radiocarbon age. Results from installation, acceptance tests and the first results of 14C analyses of reference materials prepared in our own facility are presented.

    To provide evidence and input for monitoring child welfare and wellbeing in Mexico. Adjusting for sampling design, information from ENSANUT 2012 for children <10 years was compared with national and international parameters and goals. While 8.37% of infants were born with low birth weight (<2,500 g), neonatal screening was not performed on 9.4% of newborns. Of children <5 years, 78.03% were breastfed until at least four months. Among mothers of newborns, 69.5% received training in early stimulation. At the national level, 28% of children (23% in rural areas) received five medical consultations to monitor their early development. 29% of children either had a disability or were at risk of developing one. Progress has been made in Mexico in terms of services promoting early child development and wellbeing but important challenges persist. National standards and a system for monitoring, screening, referring and providing care for child development and wellbeing are necessary.

    1989-01-01

    Industrialization and its concomitant social and environmental effects in developing countries are considered in this paper. Mexico offers one example of economic progress achieved through the promotion of industrial growth. Recognising the need for trained experts with global experience in occupational health, the University of Arizona (UA) has begun a programme to train occupational and preventive medicine residents in international aspects of occupational health in the nearby industrialized border regions of Mexico. By using the maquiladora (assembly plant) industries and the resources of the Instituto Mexicano del Seguro Social with the State of Sonora, residents observe existing problems in occupational safety and health in addition to adding to their understanding of the need for worldwide cooperation for research and reform in this field.

  12. 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)

    1999-01-01

    The future gas supply potential from the offshore Gulf of Mexico region was discussed with particular emphasis on the issue of whether there is enough growth potential to satisfy the anticipated growth in power generation markets. In 1980, a forecasted decrease in gas supply proved to be wrong. In fact, supply actually increased and productivity in the Gulf of Mexico has been relatively stable since 1982. A significant growth has been forecasted for 1997 to 2010. This growth will coincide with a large growth in gas demand in the northeastern U.S. The fact that electric power generation is changing hands adds to the opportunities in the northeast. It was emphasized that Canadian supply must be present to compete. 1 tab., 16 figs

  14. Mexico's development strategy for the 1980s

    Energy Technology Data Exchange (ETDEWEB)

    Hardy, C

    1982-06-01

    In examining the problems and prospects of the Mexican economy in the 1980s, the main concern of this paper is whether Mexico will use its new found wealth to correct some of the major deficiences of past policies or whether the development of the energy sector will further increase the dualism between the modern and traditional sectors. This paper surveys the major problems now facing the economy (poverty and unemployment, declining agricultural production, a weak industrial base, inflation) and then discusses the framework in which Mexico proposes to deal with these problems, in particular the priority allocated to development of oil and gas. The policies are then compared briefly with the experience of Japan and Iran. The conclusion takes a critical view of current Mexican policies and suggests that a more equity-oriented and efficient growth strategy is required. 18 references, 2 tables.

  15. Adolescents get the picture in Mexico.

    Science.gov (United States)

    1999-11-01

    The Mexican Family Planning Association (MEXFAM) started the Gente Joven program in 1986, targeting young people in the neediest urban and rural areas of Mexico to counteract the lack of sexual and reproductive health information and services for the youth. This lack of information has led to over half a million children being born to teenage mothers each year in Mexico. Studies also show that only 1 in 6 sexually active teenager uses some kind of protection against unwanted pregnancies and sexually transmitted diseases. To address this problem, the Gente Joven program disseminates adolescent sexual health information, produces IEC materials, provides adolescent health services and trains health and education professionals in human sexuality. As part of the program, audiovisual equipment was purchased and used since it has shown to be very effective in disseminating information. The purchase of audiovisual equipment for 36 MEXFAM clinics and centers would mean that field level staff would be able to carry out their duties more effectively.

  16. Status of geothermal resources in Mexico

    1990-01-01

    Except for some isolated instances with tourist or therapeutic objectives and some attempts in the Cerro Prieto geothermal field, there are no projects for direct heat utilization of geothermal resources in Mexico. Therefore, all places that are studied are studied with geothermal-electric objectives. It is convenient to keep in mind that in Mexico, by law, the Comision Federal de Electricidad (CFE) is the public utility in charge of electrical energy service. This institution is directly responsible for the exploration, development and commercial use of geothermal energy for electrical generation. Therefore, this paper includes the present and planned exploration and utilization of geothermal resources only for electricity generation for the period 1985 to the present. Likewise, starting 5 years ago, the CFE efforts have been directed toward the development of high enthalpy fields

  18. Listeriosis in Mexico: Clinical and epidemiological importance

    Directory of Open Access Journals (Sweden)

    Gloria Castañeda-Ruelas

    2014-11-01

    Full Text Available Listeriosis is caused by Listeria monocytogenes, an important food-borne disease due to its clinical forms, high mortality rate, and the economic impact in both clinical and food production industries. In Mexico, the lack of epidemiological surveillance systems leads to the need of accurate data on the incidence of listeriosis and its association with food-borne disease. In this paper, we present data about the presence of this bacterium in food, reports related to clinical cases of listeriosis, and information of diseases in which L. monocytogenes may be involved. However, in most of these cases the etiology was not established. Given this, there´s a need to inform and warn the appropriate entities, to define strategies for the mandatory search of L. monocytogenes through the whole food production chain and clinical suspects, for the epidemiological importance and control of listeriosis in Mexico.

    An exploratory study of the perceptions of 156 abortion clients in Mexico suggests that perceived quality of service was the main reason for choosing physicians while cost and anonymity were the major reasons for choosing nonphysicians. "Too young" was the most often cited reason for pregnancy termination, followed by economic situation and having too many children already. Cost was, on average, equivalent to three to four weeks minimum wage; physicians' charges were about three times higher than those of nonphysicians.
