    The Sierra Madre Occidental (SMO) volcanic province is characterized by voluminous silicic ignimbrites that reach an accumulated thickness of 500 to 1500 m. A single ignimbrite can reach up to 350 m thick in its outflow facies. This ignimbrite sequence formed mostly within 38-23 Ma, building up a total estimated volume of ca. 580,000 km3 making the SMO the largest ignimbrite province of the world. We have showed that several and probably most of the SMO ignimbrites were erupted from fissures associated to Basin and Range fault systems or grabens (Geology, 2003), thus naming these volcano-tectonic structures as graben calderas (Caldera Volcanism book, Elsevier, 2008). Generally, the sequence observed in graben calderas include, from oldest to youngest, alluvial fan deposits combined with lacustrine deposits, pyroclastic surge deposits and minor volume ignimbrites, a large-volume ignimbrite that could be massive or made of successive layers, and sometimes silicic lava domes and/or mafic fissural lavas both with vents aligned with the graben trend. Fallout deposits, plinian or non-plinian, are not observed in the sequence. Thus, onset of caldera collapse represented by the major ignimbrite must occur just after deposition of continental sediments within the graben domain. A similar volcano-tectonic development is observed in pull-apart grabens. Therefore, extensional or transtensional tectonics, before and during caldera collapse, and the emplacement of a subgraben shallow silicic magma chamber are the necessary conditions for the development of graben calderas. We describe here the case of the Guanajuato graben caldera, located in the central part of Mexico and in the southeastern portion of the SMO volcanic province. The caldera is part of the economically important mining district of Guanajuato, with 28 silver mines, some active since the 16th century. The caldera structure, a rectangle of 10 x 16 km, was controlled by NW and NE regional fault systems. Most ore

    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 There is no doubt that music is one of the most universal arts, with a great amount of followers. However, musicological research is still very limited inside Mexico, particularly out of Mexico City and Guanajuato is no exception to this situation in spite of its wealth in musical traditions of all sorts, such a region, remains as an unknown musical arena. Therefore, are search project was undertaken to discover, locate and classify sources of written information about Guanajuato's music, beginning with its capital. The main objective of this work was to shed a small ray of light in the dark and “deaf” panorama of Guanajuato’s musical sounds, and consequently develop future research and contribute to a deeper knowledge of the rich and important musical heritage found in Guanajuato. La música, sin dudas, es una de las artes más universales y que tiene mayor cantidad de adeptos. Sin embargo, aún son muy reducidas las investigaciones musicológicas que se realizan en el país, sobre todo, fuera de la ciudad de México. Guanajuato no escapa a esta situación y permanece como un territorio virgen, a pesar de su riqueza en cuanto a manifestaciones musicales de todo tipo. Por ello, con el fin de dar al menos un rayito de luz al oscuro y “sordo” panorama del arte de los sonidos en el estado, se emprendió un proyecto de investigación para descubrir, localizar y clasificar fuentes de información escrita acerca de la música – partiendo de la capital-, que faciliten el desarrollo de futuras investigaciones musicales, y contribuyan a profundizar en el conocimiento de este rico e importantísimo patrimonio que es la cultura musical en Guanajuato.

    Full Text Available The aim of our research is to better understand the Guanajuato Town Council as well as to explore the town’s importance in eighteenth century Mexico. Since the mining industry was the greatest contributor to Guanajuato’s economy, the substantial population of miners constituted the most powerful group in the society. By analyzing the history of the mining industry in Colonial Mexico, this study demonstrates to what extent the town council reflected the socioeconomic network created by the mining elite.

    Este trabajo trata sobre la corporación municipal guanajuatense, de forma que pueda conocerse la relevancia que tuvo en el desarrollo de la vida local. Así, el estudio de la red socio-económica que conformaba la élite minera de la villa, que se hizo con los cargos municipales, ayuda a comprender cómo el Cabildo se constituyó en un fiel exponente de la sociedad del Guanajuato colonial. Al ser la minería la actividad sobre la que se vertebraba la economía guanajuatense, es fácil comprender que los mineros fueran el grupo más representativo y más poderoso de la cúspide social y política de la villa. Por tanto, el estudio de los mineros integrados en el Cabildo de Guanajuato supone también conocer los intereses de la minería del lugar y, con ello, la evolución de la actividad por la que Guanajuato alcanzó en el siglo XVIII fama mundial.

    The semi-arid environments harbor nearly 40% of biodiversity, and half of indigenous cultures of Mexico. Thousands of communities settled in these areas depend on agriculture and using wild biodiversity for their subsistence. Water, soil, and biodiversity management strategies are therefore crucial for people's life. The tajos, from Sierra Gorda, are important, poorly studied, biocultural systems established in narrow, arid alluvial valleys. The systems are constructed with stone-walls for capturing sediments, gradually creating fertile soils in terraces suitable for agriculture in places where it would not be possible. We analyzed biocultural, ecological, economic and technological relevance of the artificial oasis-like tajos, hypothesizing their high capacity for maintaining agricultural and wild biodiversity while providing resources to people. We conducted our research in three sections of the Mezquital-Xichú River, in three communities of Guanajuato, Mexico. Agroforestry management practices were documented through semi-structured and in-depth qualitative interviews. Vegetation composition of local forests and that maintained in tajos was sampled and compared. Tajos harbor high agrobiodiversity, including native varieties of maize and beans, seven secondary crops, 47 native and 25 introduced perennial plant species. Perennial plants cover on average 26.8% of the total surface of plots. Tajos provide nearly 70% of the products required by households' subsistence and are part of their cultural identity. Tajos are heritage of TEK and land management forms of pre-Columbian Mexican and Mediterranean agricultural techniques, adapting and integrating modern agricultural practices. Tajos are valuable biocultural systems adapted to local semiarid conditions and sources of technology for similar areas of the World.

    Characterization of different tailings from the mining district of Guanajuato, Mexico were carried out, including a tailing from an abandoned dam 20 years ago, a dam in operation and another coming from the mixture of different companies. The three tailings presented alkaline conditions, normal salinity, aerobic environment with oxidative tendency, low humidity, very low capacity of cationic exchange, and absence of organic matter. These conditions restrict the metal mobility. The mineralogical analysis showed that the tailings contained mainly quartz, calcite and magnetite. Tailings coming from the mixture of different companies had greater total concentrations (mg/kg) of Mn (1042.8), Al (12919.8), Fe (23911.3), Cr (71.3), Pb (24.6) and Cu (19.8). The highest concentration of Zn was observed at the abandoned tailing (53.3 mg/kg). No significant concentrations of Cd and Hg were observed, although Pb (24.6 mg/kg) and Cr (71.4 mg/kg) were detected. Leaching tests indicated that metals cannot be leached in percentages higher than 0.1%, and so these tailings do not represent an environmental risk. The low leaching of metals in the studied tailings was consistent with the mineralogical and physicochemical prevailing conditions, the low acid drainage generation potential and the high degree of stability observed in the tests of metals fractionation. The mineralogical characteristics were determined by X-ray diffraction. (Author)

    This article presents the results of the study on sedimentation, sedimentary environments, tectono-sedimentary and paleogeographic evolution of post-Laramide clastic deposits and pre-volcanism of the Sierra Madre Occidental in the Sierra de Guanajuato, central Mexico. The Eocene Duarte Conglomerate and Guanajuato Conglomerate were deposited in the middle and distal parts of alluvial fans. The studied rocks are composed of limestone clasts, granite, andesite, metasediments, diorite, and pyroxenite, indicating the erosion of uplifted blocks of the basal complex of the Sierra de Guanajuato (Arperos basin). The petrographic and compositional analysis of limestone shows a textural variation from basin limestones and shallow platform limestones. The shallow platform limestone contain bivalves, brachiopods, gastropods, echinoderms and benthic foraminifera from the Berriasian-Valanginian. The shallow-water limestone corresponds to the boundary of the Arperos basin whose original outcrops currently not outcrop in the Sierra de Guanajuato. (Author)

    In many parts of the world, small-scale traditional brick kilns are a notorious informal sector source of urban air pollution. Many are both inefficient and burn highly polluting fuels that emit significant levels of black carbon and other pollutants into local communities and to the atmosphere, resulting in severe health and environmental impacts. It is estimated that there are nearly 20,000 traditional brick kilns in Mexico, in which bricks are still produced as they have been for centuries. They are made by hand, dried in the sun, and generally fired in small, one chamber kilns that use various types of fuels, including plastic refuse, used tires, manure, wood scrap, and used motor oil. Three brick kilns, two traditional kilns and an improved kiln (MK2), were sampled as part of the SLCFs-Mexico campaign in Guanajuato, Mexico during March of 2013. The concept of the MK-2 involves covering the kiln with a dome and channeling the output of an active kiln through a second, identical loaded kiln for its additional filtration of the effluents. The results of energy efficiency and carbon mass balance calculations are presented for comparing the production efficiency and carbon emissions from the sampled kilns. Measurements included PM2.5 mass with quartz filters and temporally-resolved elemental carbon and organic carbon composition obtained using thermo-optical methods. The carbon emissions obtained with the mass balance method are compared with concurrent, high- time resolution, emissions measurements obtained using the Aerodyne mobile laboratory employing the tracer method (see abstract by Fortner et al.)

    In this research we focus on the medical evangelist Levi B. Salmans, and The Good Samaritan sanitarium. Doctor Salmans lived in Mexico for about 50 years (1885-1935). During the first part of his stay, he was devoted to found churches and Methodist schools. However, from 1891 he took a turn in his career by founding dispensaries in different towns of Guanajuato to create, in 1899, the private charity association for the sick and infirm The Good Samaritan. His intense, intellectual, and practical work led him to create health journals, to train nurses, and to promote physiotherapies in accordance with the science advances of that time. By itself, this research shows that the history of medicine in Mexico still has long way to go and that Protestant communities, in favor of modernity and scientific knowledge, took a big part in shaping the history of this discipline in Mexico.

    Sandoval, Ricardo

    Guanajuato State, located in central Mexico, with less than 2% of the country's area, has almost 17,000 deep water wells, from which nearly 4,000 cubic hectometers (hm3) per year are being extracted, more than 1,000 hm3 over the estimated renewable yield. Since, in Mexico, water is administered under federal jurisdiction by the National Water Commission (CNA, for its Spanish acronym), the state government faces the challenge of ensuring its population's economic development without formal means of intervention. Being thus limited to apply mandatory policies and measures, the state water program has focused on the implementation of a two-sided strategy. First, basic hydrogeological studies and mathematical groundwater hydrodynamic models were developed upon a comprehensive survey of existing wells and a general revision of the state's geological framework. Second, a structure for water user's participation in water management actions was promoted (from the dissemination of information to the implementation of pilot efficient water use projects) with financial, technical and political support from the state. Simultaneously, a coordinated effort towards the completion of the water user's registry was performed with the federal authority along with other supporting measures such as training and monitoring programs. In this paper, a general overview of the project's achievements and challenges is presented. L'État de Guanajuato, situé dans la partie centrale du Mexique, avec moins de 2% de la surface du pays, a près de 17 000 puits profonds, d'où sont extraits près de 4 000 hm3 par an, soit plus de 1 000 hm3 de plus que le débit renouvelable estimé. Comme au Mexique l'eau est administrée dans le cadre d'une juridiction fédérale, le gouvernement de l'État fait tout son possible pour assurer le développement de sa population sans moyens formels d'intervention.

    Full Text Available This article examines the issues being faced by small-scale strawberry producers from Guanajuato, who supply the largest city in Mexico, are facing to market their product. This case study analyzes the situation of ejidatarios from the La Soledad ejido, located in Irapuato, Guanajuato, and their dependency on a consolidated network of local and regional intermediaries as the only alternative to sell their products. Various aspects related to the perishable nature of their production, namely the lack of infrastructure (transport, packaging and processing, of trade-related regulations, of information about production and marketing, of financial means and the current disorganization altogether summarize their dependency from intermediaries, as well as the economic results from their activity. For comparison with other types of producers, the case of mid-sized and large farmers was also studied, revealing that the typology of farmers is closely related to the way these agents sell their products, and to the economic results of these transactions. I also examined the links between intermediaries and wholesale agents in the Mexico City´s Central de Abastos, as well as those between these agents and retailers, in order to provide a complete scenario of the production chain studied.

    Full Text Available Mexican historiography concerning the presence of Africans and their descendents in Mexico has emphasized slaves and free-persons, but there has been little writing on analyzing the relationships between the owners of slaves and the slaves in everyday life. In the essay that follows, I discuss the relationship between the slave owners and the relationships that developed between slave owners and their slaves. My study will give emphasis to the formation of families, the interaction between the countryside and the city, conflicts and participation in the economy (fishing, mining and commercial ventures. Essentially, this is a family study, based on serial records from the local notary archives and other judicial sources. Although originally my analysis focuses on the relationships of the Busto family, I will only use this group as the analytical framework and as a unifying group of a wide region that includes the Altos de Jalisco, the Bajio of Guanajuato and Queretaro.//La historiografía mexicana relacionada con la presencia de africanos y sus descendientes en México ha puesto énfasis en los esclavos y en las personas libres pero ha dejado de lado el estudio de las relaciones entre los dueños y sus esclavos en la vida cotidiana.

After many years of having detected the problem, the basic epidemiologic aspects ofthis problem in the State of Guanajuato are still unknown. Material and methods: From the data gathered by the Unified System of Epidemiologic Vigilance of the Guanajuato State Health Ministry, a descriptive, retrospective and observational, study was carried out during the 2000-2005 period, from which the incidence rate per municipality and an epidemiologic map were obtained. Results: During the years 2000-2005 a total of 149,068 cases were reported with an average rate of 500.9 per 100,000 inhabitants; the 15 to 44 year-old group was the most affected; the months with the highest incidence were from April to June. The 15 municipalities with the highest incidence rates (500.9 – 1991.6 during this period were located in the southeast, and the low incidence zones (1.4 in the northeast ofthe state. Conclusions: The municipalities with the highest incidence rates require greater efforts and actions to diminish the morbidity in these areas, with a primary attention program directed to solve this serious public health problem.

    The aim of this study was to determine the seroprevalence and presence of Chlamydia abortus in Saanen breed female goats from commercial dairy goat farms under intensive production in the municipality of Guanajuato, Mexico. Sera were collected to determine the prevalence of anti-C. abortus IgG antibodies using recombinant enzyme-linked immunosorbent assay (rELISA) and cell culture. Polymerase chain reaction (PCR) was used to prove the presence of the pathogen in swab samples collected from the vagina and rectum of selected animals. Additionally, foetal tissue samples from a sudden abortion were collected. C. abortus prevalence in female goats of commercial milking farms sampled in Guanajuato, Mexico, was 4.87% (n = 246). Seropositive animals were found in six out of nine (66.6%) dairy goat farms sampled, and prevalence among animals in individual farms ranged between 3.44 and 13.51%. C. abortus was detected using PCR in spleen tissue from the aborted foetus. PCR-based detection, as well as isolation from vaginal and rectal swabs, was not possible in the present study. Isolation through cell culture was also unsuccessful from aborted foetal tissue samples. In conclusion, the results from rELISA and PCR show that C. abortus is present in dairy goat farms in the state of Guanajuato, Mexico.

La carencia de una datación para la edad de abandono del sitio, detallada en relatos etnohistóricos, así como de carbón asociado a esta etapa, motivó la aplicación de un método alternativo de datación, independiente de los métodos tradicionales. La edad obtenida en este estudio, como la más probable para la última exposición al fuego del piso analizado, es bastante congruente con las evidencias arqueológicas disponibles para el sitio Plazuelas. Difícilmente una exposición posterior al fuego (ya sea de origen natural o provocada por el hombre daría como resultado una combinación de valores para los tres parámetros magnéticos determinados que convergieran en el intervalo de edad estimado para el abandono del sitio en cuestión. ENGLISH: The results of the archaeomagnetic dating of a burned floor from the archaeological site Plazuelas, Guanajuato, Mexico, are presented. The lack of an absolute date for the age of abandonment of the site, which is detailed in ethnohistorical accounts, as well as the lack of carbon remains conclusively associated with this stage, led to the implementation of an alternative method. The age obtained in this study, most likely representing the floor’s last exposure to fire, is quite consistent with the available archaeological evidence for the site’s date of abandonment. A subsequent exposure to fire (either natural or anthropogenic would not likely yield a combination of three magnetic parameters that would converge around the estimated period of abandonment of the site under study.

    The Sierra de Guanajuato Range (SGR), trending N315° at Central México, is an orographic feature extending over a distance of 80 km. SGR comprises three well defined lithostratigraphic units: (1) a cretaceous basement including an arc-derived terrane named Guanajuato Arc (GA) made of gabbro, diorite and basaltic pillowed lava, and volcano-sedimentary rocks belonging to Arperos fore-arc basin which are geochemically anomalous in Au (0.15 ppm), Ag (3 ppm), Cu (40 ppm), Pb (50 ppm) and Zn (15 ppm); (2) Early Tertiary intrusive rocks, e.g., Comanja Granite which is affected by the presence of tourmalinized (schörl) aplito-pegmatite dykes mineralized with rare earths elements, and (3) Eocene redbeds (1,500-2000 m) and Oligocene-Miocene volcanics cover. The metallogeny of the SGR shows a multiple origin in time and space: volcano-sedimentary, granitic and volcanic, being possible to define three metallogenic epochs: cretaceous, paleocene and oligocene. Cretaceous epoch includes: (a) volcanogenic massive sulphide deposits (VMS) of bimodal-siliclastic type belonging to León-Guanajuato district; wallrock of VMS is made of felsic-internediate volcanics and black argillite; at Los Gavilanes deposit paragenesis is next: chalcopyrite > sphalerite > galena, pyrite > pyrrhotite > marcasite; grade is as follows: Au: .02-.07 g/t; Ag: 157-18.5 g/t; Cu: 2.24-0.81%, Pb: 4.16-0.03%; Zn: 10.35-3.02 %; (b) lens-shaped stratiform bodies of massive pyrite (i. ex., San Ignacio prospect; ˜ 4,000 ton) of exhalative-sedimentary origin with chalcopyrite and sphalerite microveins. Paleocene epoch includes both quartz-cordierite-sanidine veins and replacement bodies of hydrothermal metamorphic filliation (W +Se-Bi, Pb, Zn, Cu), and pyrometasomatic bodies [Cu, Pb, Zn (Ag), W] which genetically are linked to Comanja Granite emplacement. The wallrock at El Maguey mine (35,000 ton; 0.6% WO3) is made of hornfel and the vein (1.8-3.2m width) has a banding structure made of : \\{quartz & K

    Garlic in Mexico is one of the most profitable vegetable crops, grown in almost 5,451ha; out of which more than 83% are located in Zacatecas, Guanajuato, Sonora, Puebla, Baja California and Aguascalientes. Blossom-end rot caused by Fusarium spp is widely distributed worldwide and has been a limiting factor in onion and garlic production regions, not only in Mexico but also in other countries. The presence of Fusarium oxysporum has been reported in Guanajuato and Aguascalientes. Fusarium culmorum has been reported in onion cultivars of Morelos; and Fusarium proliferatum, Fusarium verticillioides, Fusarium solani and Fusarium acuminatum have been previously reported in Aguascalientes. The goal of this work was identifying the Fusarium species found in Zacatecas, Guanajuato and Aguascalientes, to assess their pathogenicity. Plants with disease symptoms were collected from hereinabove mentioned States. The samples resulted in the identification of: F. oxysporum, F. proliferatum, F. verticillioides, F. solani and F. acuminatum species; out of which Aguascalientes AGS1A (F. oxysporum), AGS1B (F. oxysporum) and AGSY-10 (F. acuminatum) strains showed higher severity under greenhouse conditions.

    Full Text Available Abstract. Agriculture, generally speaking, is the basis of thefood system of any country. Mexico’s maize crop is particularly important, not only in terms of food security but also as in terms of culture and identity. The fact that, in recent decades, Mexico has positioned itself as the second largest importer of maize is worrying. For the purpose of measuring the private sector profitability of maize production in the Bajío region of Guanajuato, this study analyzed data from 2,996 producers who participate in the “High Yield Maize Assessment Program (PROEMAR”, of the Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias- Bajío Experiment Camp (INIFAP-CEBAJ. We used the Policy Analysis Matrix (PAM developed in 1989 by Monke andPearson. The results indicate that the benefit-cost ratios of the three technological systems analyzed (considering in their total income, the sale of grain and sub products, were 2.20 for rainfall (T; 1.50 for irrigation with livestock (RCA and 1.01 for irrigation without livestock (RSA, excluding land costs; including land costs decreased the ratios to 2.13, 1.35 and 0.91. The private cost ratio (RCP, excluding the land, by production system was: T = 0.04, RCA = 0.13 and RSA = 0.85, which implies that the maize producers in the Bajío region of Guanajuato are competitive. When includingland rent in the production costs, the rainfall and irrigation with livestock systems remained competitive with a RCP of 0.07 and 0.32, respectively; not so for the production unit with the irrigation system without livestock (2.04. The most significant input was fertilizer costs, which represented 50% of the costs. / Resumen. La agricultura en general es la base del sistema alimentario de cualquier país.

We offered HCV-testing and applied audio computer-assisted self-interviews to all adults imprisoned in the State Prison System. We used a complex survey analysis to estimate the distribution of variables and its corresponding 95% confidence intervals, taking into consideration the expected cluster effect by common characteristics within prisons. Inverse probability weights were applied to correct potential biased estimates arising from non-participation in accrual activities and non-response rates. We fitted multivariate logistic regression models to identify risk-behaviors associated to HCV-infection.We included data of 2,519 participating inmates. Prevalence of HCV-infection was 4.9 (95%CI = 3.6-5.9. Most HCV-infected inmates were male (99%. Before being incarcerated, inmates with HCV-infection were more frequently tattooed, used and injected drugs more frequently, and were more likely to share materials for injecting, when compared with those non-infected. During incarceration, HCV-infected inmates got tattoos and used drugs more often than non-infected, including injecting-drugs and sharing materials. Injecting-drug use (OR = 7.6, 95%CI, 2.5-23.4, sharing materials for injecting-drugs (OR = 19.6, 95%CI, 4.7-81.7 and being tattooed at least once before incarceration (OR = 2.1, 95%CI, 1.1-3.9, but not during incarceration, were independently associated to HCV-infection.The prevalence of HCV-infection among inmates in the State of Guanajuato in Mexico is considerably higher than in the general population.

  2. The risk of supply of Surface/groundwater in the Laja River Basin in the State of Guanajuato, Mexico

    Water supply in Laja River Basin, located in an arid, semi-arid area of Central Mexico, is dependent primarily on groundwater. Although multiple users depend on this groundwater, the majority of the groundwater is used for commercial irrigation. The water table is swiftly being lowered, as the result of a rapidly growing population, expanding industries and increased commercial agriculture production in the State of Guanajuato. The average historic drawdown rate, measured in various wells across the aquifer, is ~1 m/yr; some wells approach 4 m/yr. Hydraulic heads are lower in wells in the central, low-lying areas of the basin, near the main branch of Laja River, than in wells located along the outer edges of the basin. The resulting water depth ranges from 70-130 m in most of the area. As wells are drilled deeper, at increased costs, to access the falling groundwater table, toxic levels of fluoride (F) and arsenic (As) are being reported for these wells. These increases in toxicity are possibly caused by induced upwelling of deeper groundwater. Based on analysis of the water, we suggest that the groundwater is fresh and suggest that the reservoir rock is not very reactive or the groundwater is young. Unfortunately, F and As were found to exceed Maximum Contaminant Levels (MCL) in several wells. Concentrations of F and As were correlated to Total Dissolved Solids (TDS) suggesting a mixing with older, deeper groundwater. Mapping of the watershed and channel geomorphology indicates that the Laja River tends to be gravel bedded in some locations and sand-bedded in other locations with highly erodible banks. At multiple sample locations, as many as four terraces were present, suggesting an actively down-cutting channel. Geophysical measurements suggest the river is well connected to the alluvial aquifer. Thus, prior to intensive pumping in the 1950's the Laja River may have been recharged by aquifers. Whereas the discharge in the Laja River is decreasing yearly, a

The 12 C(α γ) 16 O reaction cross section is extremely small at stellar temperature, this is mainly due to the Gamow energy (∼ 300KeV at T= 2x10 8 K) be much lower than the Coulomb barrier, E C.B. : = 3:142MeV. The α+ 12 C → 16 O at low energies is dominated by subthreshold states (1 - , 7:12MeV) and (2 + , 6:92MeV) of the 16 O, thus spectroscopic factors measurements of these states are very important. We propose to use the α-transfer reaction 12 C( 16 O, 12 C) 16 O * at very forward angles to obtain those spectroscopic factors. In this way, measurements of elastic and inelastic angular distributions for the 12 C+ 16 O system were performed at the TANDAR Laboratory in Buenos Aires, using an 16 O beam of E lab = 46.3MeV. These angular distributions were obtained using 8 adjacent surface barrier detectors and the measurements were performed from 5 deg to 48.5 deg with steps of 1 deg. The scattering chamber has an angular precision better than 0.1 deg. The transfer angular distributions are being analysed by DWBA using the computer code FRESCO in order to obtain the two spectroscopic factors. (author)

    Full Text Available The ceramic industry is a very important activity in several municipalities of the state of Guanajuato, where a significant and constant demand is kept for clay as raw material to formulate pastes used in the manufacturing of utilitarian and ornamental ceramic products. Traditionally, there have existed evidences about important clay deposits in the state of Guanajuato with suitable ceramic properties, which have not been completely characterized or quantified. Thus, considering the relevance of this raw materials to the ceramic industry in the region, as well as the difficulties to dispose of ceramic commercial materials with high and homogeneous quality at a low cost, the Centro de Investigaciones en Química Inorgánica and the Dirección de Fomento Minero del Estado de Guanajuato established a collaborating project focused on the study of the selected clay deposits and taking into account the following aspects: clay characterization, evaluation of the ceramic properties and calculation of the existing reserves. In this paper the results of the chemical and mineralogical characterization of the clays in the selected zone samples are presented. The results were reviewed with respect to the obtained values in the characterization of the commercial pastes ordinarily used by the potters in order to establish an initial estimation about the real potential of the clay deposits studied.

  12. Labor Migration, Drug Trafficking Organizations, and Drug Use: Major Challenges for Transnational Communities in Mexico

    González, Laura

    2009-01-01

    In our article, we present the recent findings of our ethnographic field study on drug use and the emergence of a drug use culture in transnational communities in Mexico. Transnational communities are part of a larger migratory labor circuit that transcends political borders and are not restricted to a single locality. Transnational migrants and returning immigrants link the multiple localities through their social networks. In southern Guanajuato, Mexico, using a transnational migration paradigm, we examined the manner in which transnational migration and drug trafficking organizations are contributing to a growing drug problem in these communities. We found that transnational migrants and returning immigrants, including deported workers, introduce drugs and drug use practices, and contribute to the creation of a drug use culture within the communities. The social conditions in the community that foster and proliferate drug use are many: the erosion of the traditional family, truncated kinship bases, and new social formations. These conditions are all consequences of migration and emigration. Recent drug cartel activities are also contributing to this growing drug problem. The cartels have aggressively targeted these communities because of availability of money, existing drug use, a drug use culture, and the breakdown of traditional deterrents to substance abuse. Although a number of communities in three municipalities were part of our study, we focus on two: Lindavista, a rancho, Progreso, a municipal seat. Our field study in Mexico, one of four sequential ethnographic field studies conducted in Guanajuato and Pennsylvania, was completed over a six month period, from September, 2008, through February, 2009, using traditional ethnography. The four field studies are part of a larger, ongoing, three-year bi-national study on drug use among transnational migrants working in southeastern Pennsylvania. This larger study, near its third and final year, is funded by the

    1986-01-01

    For the two heavy ion systems 12 C+ 12 C and 16 O+ 16 O by means of scattering experiments studies on the phenomena of nuclear molecules were performed. For the 12 C+ 12 C system in the range of the Coulomb wall precision measurements of the elastic scattering were performed. In the two energy ranges of 5.5 ≤ E c.m. ≤ 6.65 MeV and 6.95 ≤ E c.m ≤ 7.375 MeV where the existence of many quasimolecular resonances is known in energy steps of ΔE c.m. = 25 keV angular distributions in the range 10 0 ≤ θ c.m. ≤ 90 0 with Δθ c.m. = 1 0 were measured. For several of the found quasimolecular resonances the spin and the carbon width could be uniquely determined. This was reached by a partial wave analysis of the obtained data. Supplemented were the measurements of the elastic scattering by measurements of the excitation function of the θ 0 exit channel of the reaction 12 ( 12 C, θ) 20 Ne in the energy range from 5.2 ≤ E c.m. ≤ 6.1 MeV. At some known resonances in the 16 O+ 16 O system in the energy range from 15.5 MeV to 18 MeV the spin and the elastic width of these structures could be determined. For this a constrained partial wave analysis on complete angular distributions of the elastic scattering (9 0 ≤ θ c.m. ≤ 90 0 ) which were measured in energy steps of ΔE c.m. = 50 keV was performed. In the 16 O+ 16 O system besides the proof for the existence of a nuclear glory scattering was given. (orig.) [de

  16. The traditional food of migrants: Meat, water, and other challenges for dietary advice. An ethnography in Guanajuato, Mexico.

    Smith-Morris, Carolyn

    2016-10-01

    The term "traditional diet" is used variously in public health and nutrition literature to refer to a substantial variety of foodways. Yet it is difficult to draw generalities about dietary tradition for specific ethnic groups. Given the strong association between migration and dietary change, it is particularly important that dietary advice for migrants be both accurate and specific. In this article, I examine the cultural construct of "traditional foods" through mixed method research on diet and foodways among rural farmers in Guanajuato, MX and migrants from this community to other Mexican and U.S. destinations. Findings reveal first, that quantitatively salient terms may contain important variation, and second, that some "traditional" dietary items -like "refresco," "carne," and "agua" - may be used in nutritionally contradictory ways between clinicians and Mexican immigrant patients. Specifically, the term "traditional food" in nutritional advice for Mexican migrants may be intended to promote consumption of fresh produce or less meat; but it may also invoke other foods (e.g., meats or corn), inspire more regular consumption of formerly rare foods (e.g., meats, flavored waters), or set up financially impossible goals (e.g., leaner meats than can be afforded). Salience studies with ethnographic follow up in target populations can promote the most useful and accurate terms for dietary advice. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To determine diet and nutrition practices and the economic and social situation in homes with premature infants. A descriptive cross-sectional study of 100 preterm infants 30 to 36 weeks gestational age, using data obtained on weight, length and head circumference at birth, and whether they were from rural or urban communities. The mothers of premature infants were given a questionnaire to find out the diet and nutrition status, and the economic and social situation in the families. The preterm infants were recruited from Maternal and Child Hospital of Leon, Guanajuato. The mean gestational age was 34 weeks (26 to 36). The mean weight, length, and head circumference at birth were: 2,007 g (659 to 3,750 g), 43.7 cm (30 to 52 cm) and 32.4 cm (28 to 35.5 cm), respectively. Almost all mothers (98%) wished to breastfeed. More than a quarter (26%) of mothers consumed soda drinks twice a week, and preferred processed food instead of preparing it at home. Fresh fruit was consumed on seven, four, and three days per week by 43%, 13%, and 21% of mothers, respectively. These amounts were similar for vegetables, legumes and cereals. Almost all (91%) referred to consuming tortillas every day. The average monthly income was 1,000 to 4,000 pesos (62.5-250 €) in most cases. Drinking water and electricity services were scarce. Most patients did not have drinking water or electricity services, as well as being on a low income. Diets were inadequate both in quality and type of food. The accessibility to foods was limited. These situations will have an impact on the growth and development of preterm infants. Copyright © 2011 Asociación Española de Pediatría. Published by Elsevier España. All rights reserved.

The profile of students seeking entry into institutions of higher education was studied in order to identify which personal factors, such as gender, educational path, socioeconomic background and locality, have an influence on access to higher education programs at the Universidad de Guanajuato in the academic year 1997-1998. Results show several differences: Family income is higher for accepted applicants than for non-accepted ones; more male than female applicants were accepted; more residents from the industrial corridor were accepted than from other localities; and there was more intergenerational social mobility of children in reference to mothers than fathers. Uncovering the origin of educational inequities and knowing the relations between socioeconomic features of prospective students will permit the understanding, prevention, and management of educational inequalities in our society.

  9. Realizing Abortion Rights at the Margins of Legality in Mexico.

    Science.gov (United States)

    Singer, Elyse Ona

    2018-06-20

    I analyze the alternative tactics and logics of Las Fuertes, a feminist organization that has taken an "alegal" approach to realizing the human right to abortion in the conservative Mexican state of Guanajuato. Since a series of United Nations agreements throughout the 1990s enshrined reproductive rights as universal human rights, Mexican feminists have adopted the human rights platform as a lobbying tool to pressure the government to reform restrictive abortion laws. This strategy bore fruit in Mexico City, with passage of the historic 2007 abortion legalization. Las Fuertes has leveraged the human rights strategy differently - to justify the direct provision of local abortion accompaniment in a context of near-total abortion criminalization. By directly seizing abortion rights, rather than seeking to implement them through legalistic channels, Las Fuertes has effectively challenged Mexican reproductive governance in an adversarial political environment.

  12. Guanajuato, «World Heritage City». Opportunity or challenge for sustainable tourism?

    Directory of Open Access Journals (Sweden)

    María Inés Ortiz Álvarez

    2017-11-01

    Full Text Available The city of Guanajuato was recognized in 1988 as a World Heritage Site. Since then, tourism has become the greatest financial resource for the inhabitants. However, the large number of visitors creates traffic problems, rising prices and an increase in the amount of rubbish owing to the physical characteristics of the site and its population structure. To reduce these inconveniences, it is necessary to consider issues related to sustainable tourism. This should stimulate local development, and take action to safeguard the heritage of the city and prevent its decline. This paper describes the origin of the city, and problems affecting the local population and the sustainability of its tourism.

    Prominent gross and intermediate width structures are observed in the 12 C+ 12 C, 12 C+ 12 C((2 + ), 1 C((2 + )+ 12 C((2 + ), 8 Be+ 16 O, and 8 Be+ 16 O + (3 - , O + ) decay channels following 24 Mg* population via the 12 C( 16 O,α) 24 Mg reaction at E/sub c.m./ = 33 MeV. Evidence that the 12 C( 16 O,α) 24 Mg reaction populates states in 24 Mg which are associated with 12 C+ 12 C resonances is presented in the form of correlation analyses between the α+ 12 C+ 12 C three-body spectra and previously measured 12 C+ 12 C elastic and inelastic excitation functions. Direct determination of 12 C+ 12 C widths from these measurements is obscured by a background of other strong transitions which appear to be present in the 12 C( 16 O,α) 24 Mg singles spectrum

    2016-01-01

    Full Text Available This article focuses on some of the main results of the project Gender, Violence and Marginalization in elementary schools and high schools in southern Guanajuato. What was found is that a high number of female students presented some types of violence by either her classmates or teachers. Gossip and insults by other women were the main types of violence detected among female students analyzed; and also insults and gossip by men stood out. Both, male and female teachers, use violence towards some students, strengthening patriarchal ideas about what a woman has to be and punishing those who do not adhere to these stereotypes. Surveys were applied by using a sample; workshop surveys and deep interviews were conducted among students and teachers.

    Full Text Available The objective of this study was to increase the productivity of maize in High Valleys of Mexico, at the Valley of México and Bajio Experimental Stations of the National Institute for Forestry, Agriculture and Livestock Research (INIFAP. The following activities were carried out: production of registered seed to strengthen seed micro- enterprises of national capital, quality evaluation of certified seed, and generation of production technology. Between 2005 and 2013, 46.71 tons of registered seed of the hybrids parents: H-40, H-48, H-50, H-52, H-66, H-70 and H-161, and the varieties: VS-22, V-54A and V-55A were produced and sold to 31 seed producers in the Estado de Mexico, Tlaxcala, Puebla, Hidalgo, Morelos, Guanajuato, Michoacan, and Jalisco; that satisfied 60 % of demand per year (8.68 t. In 2013 and 2014, agreements were signed between INIFAP and four micro-enterprises to produce registered seeds. The certified seed produced by companies reached certification standards, germination percentage ≥ 85, 98% pure seed and less than 2% inert matter; test weight between 72 and 78 kg/hl, thousand seed weight between 288 and 361 g and genetic quality between 96 and 98 % of the true type plants. The study identified information about locations, potential yields, population density, and planting dates for the production of parents, lines and single crosses, in the Estado de Mexico and Tlaxcala.

    Full Text Available En el noreste de Guanajuato se puede identificar actualmente una dinámica de apertura electoral sustentada en una participación individual ciudadanizada que ha marginado progresivamente a los grupos corporados representados por unidades ejidales. Teniendo como eje el municipio de Atarjea, en este trabajo se discute la relación de ambos procesos —el agrario y el político electoral— en la configuración del espacio público. Para ello resulta de enorme utilidad la noción de parentela como una opción mucho más flexible a la rígida idea de corporativismo campesino.

    Full Text Available Thirty-two farms (n=535 cows located in the state of Guanajuato, Mexico, were sampled. Pathogens from bovine subclinical mastitis (SCM and clinical mastitis (CLM were identified by 16S rDNA and the sensitivity to both antibiotics and bacteriocins of Bacillus thuringiensis was tested. Forty-six milk samples were selected for their positive California Mastitis Test (CMT (≥3 and any abnormality in the udder or milk. The frequency of SCM and CLM was 39.1% and 9.3%, respectively. Averages for test day milk yield (MY, lactation number (LN, herd size (HS, and number of days in milk (DM were 20.6 kg, 2.8 lactations, 16.7 animals, and 164.1 days, respectively. MY was dependent on dairy herd (DH, LN, HS, and DM P<0.01, and correlations between udder quarters from the CMT were around 0.49 P<0.01. Coagulase-negative staphylococci were mainly identified, as well as Staphylococcus aureus, Streptococcus uberis, Brevibacterium stationis, B. conglomeratum, and Staphylococcus agnetis. Bacterial isolates were resistant to penicillin, clindamycin, ampicillin, and cefotaxime. Bacteriocins synthesized by Bacillus thuringiensis inhibited the growth of multiantibiotic resistance bacteria such as S. agnetis, S. equorum, Streptococcus uberis, Brevibacterium stationis, and Brachybacterium conglomeratum, but they were not active against S. sciuri, a microorganism that showed an 84% resistance to antibiotics tested in this study.

    We used a receiver function technique for imaging western Mexico, a unique area with several active seismic and volcanic zones like the triple junction of Rivera, Cocos and North American plates and the Colima volcano complex (CVC), the most active in Mexico. Clear images of the distribution of the crust and the lithosphere-asthenosphere boundary are obtained using P-to-S receiver functions (RF) from around ~80 broadband stations recorded by the Mapping the Rivera Subduction Zone (MARS), the Colima Volcano Deep Seismic Experiment (CODEX) and a local network (RESCO) that allowed us to considerably increase the teleseismic database used in the project. For imaging, we constructed several 2-D profiles of depth transformed RFs to delineate the seismic discontinuities of the region. Low seismic velocities associated with the Michoacan-Guanajuato and the Mascota-Ayutla-Tapalpa volcanic fields are also observed. Most impressive, a large and well delineated magma body 100 km underneath CVC is recognized along a surely related depression of the moho discontinuity just above it. We bring more tools for a better understanding of the deep processes that ultimately control eruptive behavior in the region.

    2018-03-01

    The averaged effective two-body interaction (AEI), which can be generated through the lowest order constrained variational (LOCV) method for symmetric nuclear matter (SNM) with the input [Reid68, Ann. Phys. 50, 411 (1968), 10.1016/0003-4916(68)90126-7] nucleon-nucleon potential, is used as the effective nucleon-nucleon potential in the folding model to describe the heavy-ion (HI) elastic scattering cross sections. The elastic scattering cross sections of 12C-12C and 16O-16O systems are calculated in the above framework. The results are compared with the corresponding calculations coming from the fitting procedures with the input finite range D D M 3 Y 1 -Reid potential and the available experimental data at different incident energies. It is shown that a reasonable description of the elastic 12C-12C and 16O-16O scattering data at the low and medium energies can be obtained by using the above LOCV AEI, without any need to define a parametrized density-dependent function in the effective nucleon-nucleon potential, which is formally considered in the typical D D M 3 Y 1 -Reid interactions.

    The 12 C( α, γ) 16 O reaction is crucial for the understanding of He burning in massive stars, but the low-energy cross section is highly uncertain. To address this problem we have measured at sub-Coulomb energies total cross sections for the 12 C( 6 Li, d) 16 O and 12 C( 7 Li, t) 16 O reactions to the bound 2 + and 1 - states of 16 O . The data are analyzed to obtain the reduced α widths of these states. Together with capture and phase-shift data, these results provide for a more accurate determination of the low-energy 12C(α, γ) 16 O S factor: S E1 (0.3 MeV) =101±17 keV b and S E2 (0.3 MeV) =42 +16 -23 keV b for the E1 and E2 multipole components of the reaction.

    Full text: The 16 O+ 12 C elastic scattering was investigated considering the effect of exchange of an alpha particle between projectile and target leading to the same nuclei of the entrance channel (elastic transfer). Angular distributions were analyzed in an energy range from 8.55 MeV to 56.57 MeV in the center of mass frame. The Coulomb barrier is around 11MeV for this system. Measurements of angular distributions of elastic and inelastic transfer reactions to states of the 16 O in the 16 O+ 12 C system were performed at the TANDAR Laboratory in Buenos Aires, using an 16 O beam of E lab = 46; 26 MeV. The transfer angular distributions were analyzed by DWBA using the computer code FRESCO. Those measurements provided the spectroscopic factors of 12 C + α → 16 O for the ground state and for J π = 2 + and J π = 1 - 16 O excited states, both just below the α-threshold at 7.16 MeV. The Asymptotic Normalization Coefficient (ANC) for the J π = 2 + state was obtained (1.05 ±0,13(10 5 fm -1/2 )) and used to calculate the reduced width of this state, with this value a R-matrix calculation was performed to determine the astrophysical S-factor in energies around the Gamow peak, S(E2)=37keVb.

Esta forma de cultivo requiere de planeación que contemple variables bioclimáticas para el óptimo desarrollo y rendimiento. El objetivo del presente trabajo fue determinar las áreas con potencial bioclimático para el establecimiento del cultivo de girasol en temporal en el estado de Guanajuato. Durante el ciclo otoño-invierno del 2016 se monitorearon y se estratificaron 45 parcelas de girasol, distribuidas en once municipios, en las que se registró el rendimiento asociado a temperatura máxima y mínima, humedad relativa, radiación solar, precipitación y evapotranspiración. Los datos de parcelas con un rendimiento mayor a 1,89 t/ha se utilizaron para generar polígonos con una saturación de 56 puntos de abundancia, para calcular la distribución potencial mediante el programa Maxent, con 23 variables bioclimáticas como predictores. Las variables con mayor contribución porcentual a la distribución potencial fueron: temperatura promedio del cuatrimestre más seco, altitud, régimen de humedad y perfil edáfico. Las áreas potenciales para el establecimiento del cultivo suman una superficie total de 317 028 hectáreas, donde el clima predominante es semicálido subhúmedo, temperatura media anual de 20 °C, precipitación media anual de 600 a 800 mm y una altitud de 500 a 1500 msnm.

    Two new rare-earth - alkali - tellurium oxide halides were synthesized by a salt flux technique and characterized by single-crystal X-ray diffraction. The structures of the new compounds Cs7Sm11[TeO3]12Cl16 (I) and Rb7Nd11[TeO3]12Br16 (II) (both tetragonal, space group I4/mcm) correspond to the sequence of [MLn11(TeO3)12] and [M6X16] layers and bear very strong similarities to those of known selenite analogs. We discuss the trends in similarities and differences in compositions and structural details between the Se and Te compounds; more members of the family are predicted.

    Full Text Available En México, a lo largo de la historia, se ha ignorado el aporte de los pueblos indígenas y se ha omitido su punto de vista para la toma de decisiones en asuntos que los atañe, no fue sino hasta el levantamiento Zapatista que la cuestión indígena despertó interés. En el estado de Guanajuato, la población indígena es menor en comparación con otros estados y, sin embargo, está conformada por un mosaico de culturas, algunas nativas y otras migrantes. A pesar de esto, la presencia de población indígena fue reconocida hasta el año 2004. El objetivo de este artículo es primeramente visibilizar la presencia de comunidades de indígenas migrantes en la ciu - dad de León, Guanajuato, y en segundo lugar, hacer un análisis de su participación ciudadana en el marco del Consejo Consultivo Indígena, como un mecanismo institucionalizado de atención para este segmento de la población.

    aim: To know the metabolic syndrome and its components prevalence in Mexico City adolescents sample. A cross-sectional survey was conducted in 772 men and 1078 women, 12 to 16 years old, from 8 randomly selected public junior high schools in Mexico City. Anthropometric variables, lipids, lipoproteins, Apo AI and B, glucose and insulin were determined. Prevalence of metabolic syndrome was 12.5%, 11.15% in men and 13.5% en women (p ns). The most frequently metabolic syndrome component found in México City adolescents was low HDL-C levels (38%), followed by hypertriglyceridemia (25.5%), hypertension (19.2%), central obesity (11.8%) and elevated fasting glucose (1.7). Except by the hypertriglyceridemia, higher in woman than in men, 28.2% vs. 21.6%, p metabolic syndrome components was similar between males and females. The high prevalence of biochemical and physiological factors of metabolic syndrome, associated with overweight and obesity in Mexico City adolescents, increases the risk of premature development of coronary atherosclerosis and diabetes mellitus in this population.

El Estado de Guanajuato, posee un interesante número de cabezas de ganado en el ámbito bovino y porcino, lo que ha originado el planteamiento del presente artículo. En este trabajo, se presenta un estudio, empleando estadísticas locales, conducente a evaluar el potencial energético disponible a partir del uso de las excretas de ganado porcino, para producir Biogás y de ahí, establecer una valoración de la energía eléctrica anual obtenible, el ahorro en equivalente a barriles de petróleo que se podría manejar y la cantidad de gases que se dejarían de añadir a la atmósfera. El estudio se realiza dividiendo el estado por municipios y estableciendo los totales de cada variable de interés en el proceso. Los indicadores muestran que dada la sencillez de implementación de biodigestores para la producción de biogás, esta debe ser una alternativa interesante e importante a desarrollar y potenciar en los próximos años en el país. En el caso particular del Estado de Guanajuato, existen cerca de un millón de cerdos de diferentes edades registrados, pudiendo producir una energía potencial para alimentar a más de 60,000 viviendas estándar.

    In myxoid/round cell liposarcoma, the t(12;16)(q13;p11) and its associated fusion transcript, FUS-CHOP, characterize greater than 95% of cases. The variant translocation t(12;22)(q13;q12) and associated EWS-CHOP fusion transcript are rare. A second non-random aberration observed in roughly 20% of Ewing's sarcomas, and to a lesser extent other select sarcomas, is the unbalanced 1;16 translocation. Recognition of this secondary aberration in the absence of an obvious primary karyotypic abnormality strongly suggests that the use of other genetic approaches will be informative in uncovering a clinically suspected primary anomaly.

MÉTODOS: Se han utilizado técnicas cualitativas de investigación. Fueron realizadas 35 entrevistas, semiestructuradas, en total entre los dos estados, a médicos colegiados, Guanajuato y Sonora, tanto de instituciones públicas como privadas y representantes de las asociaciones gremiales y sindicales. RESULTADOS: Para el gremio médico de los dos estados investigados, la descentralización ha implicado en inseguridad, como resultado de la falta de claridad en la regulación del Sector de Salud. La acción de los Colegios de Médicos de ambos estados, se tradujo en una mayor politización de los Colegios de Médicos estatales, en la elaboración de propuestas con el objetivo de incidir en el control del mercado laboral médico de dichos estados y participación en la estructura de poder regional. CONCLUSIONES: La investigación comprueba una readaptación del gremio médico en el ámbito regional, indicando su permanencia como grupo de poder.

    Full Text Available From 1994 through 1996, federal, state, and nongovernmental organizations in Mexico and in the United States of America developed and piloted a Binational Health Information System for Epidemiological Surveillance of Mexican migrant workers. The system allowed data exchange for epidemiological surveillance between the state of Guanajuato in Mexico and the Commonwealth (state of Pennsylvania in the United States, for case detection, prevention, and treatment, through shared contact investigation and case management of communicable diseases. The target population consisted of migrant workers traveling between Guanajuato and Pennsylvania to work mainly in the mushroom industry, and their sexual partners in their Mexican communities of origin. Computerized migrant health information modules were set up in Guanajuato and in Pennsylvania. Patient information and epidemiological surveillance data were encrypted and communicated electronically between the modules, using the WONDER communications system of the U.S. Centers for Disease Control and Prevention. Evaluation of the Guanajuato-Pennsylvania Binational Health Information System showed that major barriers to binational epidemiological surveillance and control are: a lack of communication binationally; b interrupted medical care due to migration; c inconsistent diagnosis and treatment criteria between the two countries; d lack of referral clinical records from one country to the other; and e deficient legal regulations concerning binational clinical data transfer. To our knowledge, this is the first project that has successfully demonstrated the technological feasibility of a binational disease control system linking a state in the interior of one country with a state in the interior of another country, rather than just states in the border region. The project also advanced the understanding of health service organizational issues that facilitate or hinder communication, outreach, disease

    Article 320 of the Criminal Code of the Federal District of Mexico defines "abortion" as the death of the conceptus at any time during pregnancy. Articles 320-32 specify penalties for inducing abortion, and Articles 333-34 exempt punishment if the abortion resulted from failure of the woman to take proper care, if the pregnancy was the result of rape, or if the pregnancy endangered the life of the woman. The abortion provisions of the criminal codes of the Mexican states of Baja California, Chiapas, Mexico, Sinoala, Sonora, Tabasco, and Tamaulipas are nearly identical to those of the Federal District Code. Certain states also give immunity from prosecution for abortion 1) if the pregnancy resulted from artificial insemination neither requested or assented to by the woman, provided that the abortion is carried out within the first 90 days of pregnancy; 2) if there is good reason to believe that the unborn child suffers from severe physical or mental disabilities of genetic or congenital origin; 3) if the health of the woman would be seriously jeopardized by the pregnancy, and 4) if the abortion is carried out for serious and substantiated economic reasons in cases where the woman has at least three children. Guanajuato and Queretaro allow abortions only when the pregnancy is the result of rape. Guerrero authorizes abortions only when the pregnancy is the result of rape, when the pregnancy results from an unlawful artificial insemination, or for eugenic reasons. Hidalgo, Nuevo Leon, and San Luis Potosi allows abortions only when the pregnancy is the result of rape or when the continuation of the pregnancy would seriously jeopardize the woman's health. In Chihuahua, Coahuila, Durango, Oaxaca, and Veracruz, abortions allowed because the pregnancy resulted from rape must be performed in the first 90 days of pregnancy.

    1993-04-01

    The Uranium Mill Tailings Remedial Action (UMTRA) Project's Technical Assistance Contractor (TAC) performed a radiological surveillance of the Remedial Action Contractor (RAC), MK-Ferguson and CWM Federal Environmental Services, Inc., at the processing site in Ambrosia Lake, New Mexico. The requirements and attributes examined during the audit were developed from reviewing working-level procedures developed by the RAC. Objective evidence, comments, and observations were verified based on investigating procedures, documentation, records located at the site, personal interviews, and tours of the site. No findings were identified during this audit. Ten site-specific observations, three good practice observations, and five programmatic observations are presented in this report. The overall conclusion from the surveillance is that the radiological aspects of the Ambrosia Lake, New Mexico, remedial action program are performed adequately. The results of the good practice observations indicate that the site health physics (HP) staff is taking the initiative to address and resolve potential issues, and implement suggestions useful to the UMTRA Project. However, potential exists for improving designated storage areas for general items, and the RAC Project Office should consider resolving site-specific and procedural inconsistencies

    Full Text Available Aims. The frequency of functional gastrointestinal disorders (FGIDs in the general population of Mexico is unknown. Methods. To determine the prevalence of FGIDs, associated depression, and health care utilization, a population-based sampling strategy was used to select 500 households in the State of Tlaxcala, in central Mexico. Household interviews were conducted by two trained physicians using the Rome II Modular Questionnaire, a health-care and medication used questionnaire and the CES-D depression scale. Results. The most common FGIDs were IBS: 16.0% (95% CI: 12.9–19.5; functional bloating: 10.8% (8.2–13.9; unspecified functional bowel disorder: 10.6% (8.0–13.6; and functional constipation (FC: 7.4% (5.3–10.1.

Throughout his career, Greenaway has made extensive use of intermedia, expanding the vocabulary of “ideogrammic montage”, a theory of film editing first proposed by Eisenstein himself. The use of hybrid forms of artistic expression allows the film to discuss the very idea of authorship and individual creation. The biopic, as a genre, became over time a platform that allows for the domestication of the figure of the artist or author and for the representation of the creative process as a purging act of the creative body. Greenaway subverts expectations regarding the biopic genre by shunning realism when representing the artist and by associating a queer identity and Eisenstein’s body to the artist’s processes of sensorial exploration and aesthetic development.

    Full Text Available Ideation and suicide attempts are important pieces of the suicide behavior spectrum. Have both relative frequencies between adolescents because in this developmental stage many important social, familiar and psychological factors intervene. The present paper, part of a broader project in the same population, was aimed to identify the prevalence and associated factors to ideation and suicide attempts among high school students of University of Guanajuato. It was applied aquestionnaire to a two stages random sample (n=2 532, age range was 13 to 22 years old. Suicide ideation indicators were founded in almost a quarter of the sample, while 8.6 % have at least one suicide attempt, generally around the age of thirteen; motives for attempting suicide were mainly referred to interpersonal or affective aspects. Almost in every studied variable, women obtained the greater percentage. Suicide Ideation, as any other suicide act, is not an isolated event, but represents a serious risk at social and personal level, and its determination has to be found in a multiplicity of factors.La ideación y el intento suicida son parte del amplio espectro del comportamiento suicida. Ambos tienen una alta frecuencia entre los adolescentes porque en esta etapa del desarrollo concurren factores sociales, familiares y psicológicos.

    Full Text Available La pregunta que se responde en este trabajo es: ¿cómo se afecta el bienestar social de los habitantes de la cuenca Lerma-Chapala, si se reduce la oferta de agua para el sector agrícola y se incrementa el nivel del lago de Chapala? Por hipótesis, el volumen total de agua que se les retira a los agricultores aguas arriba (estado de Guanajuato escurre hacia el lago de Chapala. Sin embargo, el aumento en el nivel del lago de Chapala no es concluyente en cuanto al efecto sobre el bienestar social de los habitantes de la cuenca, ya que éste dependerá a su vez de la comparación o del equilibrio que se establezca entre dos efectos que operan en sentido contrario: i el positivo ocasionado por el incremento de la valoración por el lago como un bien medioambiental, por parte de todos los habitantes de la cuenca, y ii el negativo en el bienestar de los consumidores del estado de Guanajuato, que se produce cuando aumenta el precio del bien agrícola, como consecuencia de la reducción de la oferta de agua a los agricultores y del incremento derivado en el valor del agua.

    RESUMEN En México, las transferencias formales e informales destinadas al apoyo de las personas adultas mayores son diversificadas. En este documento se analizan la tendencia nacional y los resultados de un estudio centrado en la entidad federativa de Guanajuato. La distribución de los apoyos confirma que las transferencias hechas por el sistema de seguridad social tienen un sesgo urbano y que las transferencias formales del gobierno federal se orientan a las áreas menos urbanizadas, particularmente las zonas rurales. A pesar de las transferencias formales (esporádicas e insuficientes), las necesidades económicas y de salud de las personas mayores persisten y ello lleva a que sus familiares realicen transferencias informales de naturaleza ascendente. En México —y más concretamente en Guanajuato— el apoyo de quienes residen con la persona mayor tiene un significativo peso, y lo contrario sucede con el de quienes han migrado. A partir de este material, se analiza el rol que, de acuerdo a su cohorte y su condición migratoria, desempeñan los descendientes. En todo caso, queda de manifiesto que, en cada entidad nacional, las dinámicas de transferencias intergeneracionales son de diversos tipos. PMID:29375179

    Terrorism remains a threat to international stability and security. Often national and international high level public events are the subject of much public interest and receive extensive coverage in the media. In this sense, it is well known that there is a real threat of a terrorist attack in important public events, such as major economic summits, high level political meetings or sporting events. In 1955 and 1975, the 2nd and 7th Pan American Games were organized by the City of Mexico. In 2011, the Pan American Games was the third event of its kind held in Guadalajara, Jalisco. At the national level, the implementation of nuclear security measures in the Pan American Games laid the foundations for a sustainable national nuclear security framework that will continue long after the event. The political decision, the existing legal basis and structure, agency coordination facilitated the incorporation of nuclear security measures. It was also a challenge to integrate all the relevant organizations, provide focus to the threat of terrorism linked to weapons of mass destruction for security games, plan resources and execute the project on time, among other details. For this reason, information and lessons learned that are reported in this document, received in Mexico during the 16th edition of the Pan American Games will be useful for the implementation of nuclear security measures in States with similar situations.

  8. Do People with Type 2 Diabetes Think They are Unhealthy? A Cross-Sectional Study in Celaya, Mexico

    2015-05-01

    Full Text Available Background: Type 2 diabetes is a chronic disease that presents a significant burden on health care systems in many countries. With the rise of obesity, the incidence of Type 2 diabetes has also been steadily increasing. A healthy lifestyle and understanding of diabetes management are important factors for delaying the onset of comorbidities associated with Type 2 diabetes. The objective of this study was to evaluate the self-perception of health in individuals with Type 2 diabetes as it relates to BMI status, which has important implications for the implementation of preventive programs. Methods: A cross-sectional lifestyle survey was implemented in the region of Celaya, Guanajuato, Mexico, targeting 100 participants diagnosed with Type 2 diabetes. Anthropometric measurements and participant characteristics were also obtained. Fisher’s exact test was used to determine if the proportions of lifestyles perceptions differed by BMI status. Results:  Participants had a mean age of 56.12 ± 10.26, a mean BMI of 29.13 ± 5.48 kg/m2, were mostly married (67.0%, and female (70.0%. None of the normal weight participants perceived themselves as unhealthy. 95% of overweight/obese participants perceived themselves to be healthy, despite a diagnosis of diabetes and being overweight/obese, while only 5% perceived themselves to be unhealthy. However, these differences in the perceptions of health classified by BMI status were not statistically significant (p = 0.42.Conclusion: Our findings indicate that overweight and obese persons with Type 2 diabetes in Celaya, Mexico may have misperceptions about their own health, even though these findings were not statistically significant. These preliminary data highlight the importance of implementing prevention and educational programs among those with diabetes, in order to combat health misperceptions and raise awareness about the dangers of diabetes and obesity.

    Abstract Population genetic variation and demographic history in Danaus plexippus (L.), from Mexico were assessed based on analyses of mitochondrial cytochrome c oxidase subunit I (COI; 658 bp) and subunit II (COII; 503 bp) gene segments and 7 microsatellite loci. The sample of 133 individuals included both migratory monarchs, mainly from 4 overwintering sites within the Monarch Butterfly Biosphere Reserve (MBBR) in central Mexico (states of Michoacán and México), and a nonmigratory population from Irapuato, Guanajuato. Haplotype (h) and nucleotide (π) diversities were relatively low, averaging 0.466 and 0.00073, respectively, for COI, and 0.629 and 0.00245 for COII. Analysis of molecular variance of the COI data set, which included additional GenBank sequences from a nonmigratory Costa Rican population, showed significant population structure between Mexican migratory monarchs and nonmigratory monarchs from both Mexico and Costa Rica, suggesting limited gene flow between the 2 behaviorally distinct groups. Interestingly, while the COI haplotype frequencies of the nonmigratory populations differed from the migratory, they were similar to each other, despite the great physical distance between them. Microsatellite analyses, however, suggested a lack of structure between the 2 groups, possibly owing to the number of significant deviations from Hardy–Weinberg equilibrium resulting from heterzoygote deficiencies found for most of the loci. Estimates of demographic history of the combined migratory MBBR monarch population, based on the mismatch distribution and Bayesian skyline analyses of the concatenated COI and COII data set (n = 89) suggested a population expansion dating to the late Pleistocene (~35000–40000 years before present) followed by a stable effective female population size (Nef) of about 6 million over the last 10000 years.

    Evidence for direct elastic breakup of 16 O into the α- 12 C continuum with relative energies ranging from 900 to 1800 keV has been obtained in the scattering of 1527 MeV 16 O projectiles off 208 Pb. An interpretation of E2 breakup including nuclear and Coulomb contributions leads to reduced electromagnetic transition probabilities and astrophysical S E2 factors in reasonable agreement with direct measurements, showing that the method can be applied to extract the E2 part of the 12 C(α,γ) reaction rate.

    2017-12-01

    One of the main challenges to making accurate predictions of future changes in CO2 concentration is the capability to determine what fraction of human produced CO2 remains in the atmosphere. We present our progress in the application of Tunable Infrared Laser Direct Absorption Spectroscopy (TILDAS) to the measurement of the primary clumped (13C18O16O) as well as 17O (12C17O16O) isotopologues of atmospheric CO2, as a tracer of its sources and sinks. We expect unique isotopologue signals in CO2 from high-temperature combustion sources, plants, soils, and air-sea exchange processes. High sampling frequency (a few minutes for each sample vs. reference cycle) achieved by a TILDAS instrument is expected to enable us to document local heterogeneous sources and temporal variations. The TILDAS is equipped with a newly developed 400-meter absorption cell. We designed a dual pressure measurement technique in which the clumped isotopologue, 13C18O16O, and 13C16O16O are first measured at 30 torr cell pressure. This is followed by measurement of 12C17O16O, 12C18O16O and 12C16O16O at lower ( 5 torr) cell pressure. Isotopologue ratios are compared between reference and sample gases. Preliminary tests demonstrated a precision approaching 0.03 ‰ for the ratio 13C18O16O/13C16O16O and 0.08‰ for Δ13C18O16O value (1σ repeatability for 4 min sample vs. reference cycle). Sample size for a single analysis is approximately 100 mL of air (1.6μmol of CO2). Given the previously observed range of variations for Δ13C18O16O and Δ17O values as large as 0.6 to 0.3 ‰, respectively, TILDAS offers a novel approach for real time monitoring of atmospheric CO2 isotopologues. It was found that achieving better than 0.1‰ requires careful matching of CO2 mixing ratios between reference and sample air. A primary cause of pressure and mixing ratio dependence is inaccurate baseline fitting (analogous to abundance sensitivity or pressure baseline for IRMS). Given that mixing ratios of atmospheric

    The type specimens of amphibians and reptiles of the Museo de Historia Natural Alfredo Dugès, at the University of Guanajuato (MADUG) were reviewed following Smith & Necker's (1943) summary. Owing to this collection's eventful history and its historical importance as the oldest herpetological collection in Mexico, a review of its conservation status was needed. After many years, the collection has received proper recognition at the University of Guanajuato with a portion of the herpetological types considered "Precious Assets" of the university. We found 34 type specimens pertaining to 18 taxa; six are additional specimens to those previously reported; six herpetological types are missing, including the body of the type of Adelophis copei. All specimens are in good to reasonable condition except for the type of Rhinocheilus antonii, which has dried out completely. All specimens are illustrated to show their condition.

    Full Text Available A survey was conducted to assess the frequency of BCMV and BCMNV in five of the main dry bean producing states in Mexico during the spring-summer 2009 and fall-winter growing seasons 2009-2010. States included in the survey were Nayarit, Sinaloa and Sonora in the pacific west coast, Veracruz in the gulf coast and Guanajuato in central Mexico. A total of 338 samples were collected and analyzed by RT-PCR with specific primers for each viral species. Forty-four samples (13% gave positive reaction for BCMV, 70 (21% for BCMNV and 30 (9% were positive for both viral species, 164 (48% were negative for both viruses and 30 (9% could not be defined as of yet. As for cultivars, Azufrado Higuera (Nueva Granada race grown at Sinaloa showed the highest frequency (33% of BCMV, whereas Negro Jamapa (Mesoamerica race from Nayarit displayed highest frequency (50% of BCMNV. In these two states the percentage of positive samples for either viral species was 80%. In addition, in cultivar Negro Jamapa mixed infections of both viruses were detected. Results point out a high risk of viral infection with seed movement across states, particularly since both viral species are seed transmitted and in the states at the pacific west coast, large seed lots are produced during the fall-winter season. Key words: BCMV, BCMNV, bean plants viruses RESUMEN Se llevó a cabo un muestreo en campo para estimar la frecuencia de la ocurrencia de BCMV y BCMNV en cinco estados productores de frijol en México durante los periodos de cultivo primavera-verano y otoño-invierno en el 2009 y 2009/2010.

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

    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

    Hypertension is a significant risk factor for cardiovascular disease, and epidemiological evidence suggests that it is increasing in parallel with obesity in children and adolescents in low- and middle-income countries. To identify and determine the relationship between overweight, obesity and hypertension in a community sample of school children. Anthropometric data were collected from 12,730 school children aged 12-18 years in China, India and Mexico as part of the Community Interventions for Health programme, an international study evaluating community interventions to reduce non-communicable disease by addressing the three main risk factors of tobacco use, unhealthy diets and physical inactivity. Logistic regression was used to examine the association of body mass index and gender and hypertension. Prevalence rates of hypertension were 5.2% in China, 10.1% in India and 14.1% in Mexico, and pre-hypertension rates in China, India and Mexico were 13.4%, 9.4% and 11.2%, respectively. Overweight and obesity prevalence rates varied by country and were 16.6% in China, 4.1% in India and 37.1% in Mexico. In all countries there was a significant association between overweight and obesity and rates of hypertension. Overweight children were 1.7-2.3 times more likely to be hypertensive and obese children 3.5-5.5 more likely to show hypertension than those of normal weight. Rates of hypertension and overweight and obesity are high in school children in China, India and Mexico, and increased bodyweight is a significant risk factor for hypertension.

    Northwest of Mexico City, the study area is located in the State of Guanajuato. Leon Valley has covered with groundwater its demand of water, estimated in 20.6 cubic meters per second. The constant increase of population and economic activities in the region, mainly in cities and automobile factories, has also a constant growth in water needs. Related extraction rate has produced an average decrease of approximately 1.0 m per year over the past two decades. This suggests that the present management of the groundwater should be checked. Management of groundwater in the study area involves the possibility of producing environmental impacts by extraction. This vital resource under stress becomes necessary studying its hydrogeological functioning to achieve scientific management of groundwater in the Valley. This research was based on the analysis and integration of existing information and the field generated by the authors. On the base of updated concepts like the geological structure of the area, the hydraulic parameters and the composition of deuterium-delta and delta-oxygen -18, this research has new results. This information has been fully analyzed by applying a groundwater flow model with particle tracking: the result has also a similar result in terms of travel time and paths derived from isotopic data.

    The total cross section of the 12C+16O fusion reaction has been measured at low energies to investigate the role of this reaction during late stellar evolution burning phases. A high-intensity oxygen beam, produced by the 5 MV pelletron accelerator at the University of Notre Dame, impinged on a thick, ultrapure graphite target. Protons and γ rays were simultaneously measured in the center-of-mass energy range from 3.64 to 5.01 MeV for singles and from 3.73 to 4.84 MeV for coincidence events, using silicon and Ge detectors. Statistical model calculations were employed to interpret the experimental results. The emergence of a new resonance-like broad structure and a decreasing trend in the S -factor data towards lower energies (opposite to previous data) are found for the 12C+16O fusion reaction. Based on these results the uncertainty range of the reaction rate within the temperature range of late stellar burning environments is discussed.

    Terrorism remains a threat to international stability and security. Often national and international high level public events are the subject of much public interest and receive extensive coverage in the media. In this sense, it is well known that there is a real threat of a terrorist attack in important public events, such as major economic summits, high level political meetings or sporting events. In 1955 and 1975, the 2nd and 7th Pan American Games were organized by the City of Mexico. In 2011, the Pan American Games was the third event of its kind held in Guadalajara, Jalisco. At the national level, the implementation of nuclear security measures in the Pan American Games laid the foundations for a sustainable national nuclear security framework that will continue long after the event. The political decision, the existing legal basis and structure, agency coordination facilitated the incorporation of nuclear security measures. It was also a challenge to integrate all the relevant organizations, provide focus to the threat of terrorism linked to weapons of mass destruction for security games, plan resources and execute the project on time, among other details. For this reason, information and lessons learned that are reported in this document, received in Mexico during the 16th edition of the Pan American Games will be useful for the implementation of nuclear security measures in States with similar situations

Los municipios diversificados tienen una mejor dinámica y están más a salvo de oscilaciones bruscas por la propia y natural defensa de riesgos que se neutralizan. En cambio, los monomanufactureros tienen gran exposición a los cambios con el riesgo de la viabilidad del municipio al depender sustancialmente sólo de una actividad. Los otros municipios se resguardan más en la defensa moderada de comercios y servicios, actividades no comerciables de primera necesidad.

    Full Text Available El Metate is a shield volcano located in the southern sector of the Michoacan-Guanajuato Volcanic Field, one of two largest monogenetic volcanic fields of the Transmexican Volcanic Belt. It was active c. 4.700 ± 200 years B.P and emitted about fifteen calcalkaline lava flows showing variable differentiation degrees. Temperatures calculated from mineral-liquid geothermobarometers for olivine, plagioclase and pyroxene, suggest that olivine was the earliest fractionating phase (1232–1198 °C, followed by plagioclase (1162–1126 °C, orthopyroxene (1147–1027 °C and clinopyroxene (1147–1018 °C. Pressure estimations indicate that crystallization started at ~7 kbar and progressed up to surface levels. Water contents in the melts during crystalliztion of plagioclase is estimated at ~1.6%. Temperatures calculated on the basis of Al content in amphibole, provide a crystallization range between 995 and 922 °C, at an average pressure of 3.5 kbar and water contents between 5.2% and 6.9%. Although these values could agree with a scenario where amphibole represents a late crystallization phase along the previous fractionating sequence, the systematic presence of disequilibrium textures, which are also observed occasionally in other phases, suggest that other possibilities such as open-system crystallization cannot be discarded.El Metate es un volcán en escudo situado en el sector sur del Campo Volcánico de Michoacán-Guanajuato, uno de los dos campos volcánicos más grandes del Cinturón Volcánico Transmexicano.

    The lack of spectroscopic measurements for rare CO2 isotopologues was the main motivation of this work. In our present study we report line intensity measurements for 16O12C17O made with a high resolution Fourier transform spectrometer (Bruker IFS-125HR) and a 21 m path cryogenic Herriott cell at Jet Propulsion Laboratory. For this, a 17O-enriched CO2 gas sample was used, which comes as a mixture of primary and several minor CO2 isotopologues. The mole fraction of the 16O12C17O isotopologue in the mixture was determined to be 0.3991 by mass spectrometry from a Stable Isotope Ratio Mass Spectrometer (SIRMS) under stochastic distribution assumption at thermal equilibrium. Since the collisional narrowing effect was observed, the Rautian molecular line shape profile was systematically adopted instead of the Voigt profile. Absolute line positions were also investigated by performing a wavenumber calibration based on CO, HCl and a few well-known 16O12C16O transitions. Finally, around 1000 transitions were studied between 4604 and 5126 cm-1 involving 15 bands of the 16O12C17O isotopologue. All the measured line intensities were renormalized to be the values for 100% pure isotopologue sample. Transition dipole moments and Herman-Wallis factors were derived enabling a global comparison with theoretical calculations and predictions for the 15 bands of the 16O12C17O isotopologue. For the measured line positions, the absolute accuracy is around 2×10-4 cm-1. The accuracies of retrieved line intensities are 2 - 5% for five cold and two hot bands, and 6-30% for eight other weaker hot bands. Results from this work were in a good agreement with HITRAN 2012 for positions, but showed rather significant discrepancies for line intensities. An extensive line list was generated from new experimental measurements in order to improve and validate spectroscopic knowledge of 12C16O17O isotopologue in support of atmospheric remote sensing for the Earth (e.g., OCO-2 mission), Mars and Venus.

    Background The aim of the study was to evaluate the radiation sensitizing ability of ERK1/2, PI3K-AKT and JNK inhibitors in highly radiation resistant and metastatic B16F10 cells which carry wild-type Ras and Braf. Methods Mouse melanoma cell line B16F10 was exposed to 1.0, 2.0 and 3.0 Gy of electron beam radiation. Phosphorylated ERK1/2, AKT and JNK levels were estimated by ELISA. Cells were exposed to 2.0 and 3.0 Gy of radiation with or without prior pharmacological inhibition of ERK1/2, AKT as well as JNK pathways. Cell death induced by radiation as well as upon inhibition of these pathways was measured by TUNEL assay using flow cytometry. Results Exposure of B16F10 cells to 1.0, 2.0 and 3.0 Gy of electron beam irradiation triggered an increase in all the three phosphorylated proteins compared to sham-treated and control groups. B16F10 cells pre-treated with either ERK1/2 or AKT inhibitors equally enhanced radiation-induced cell death at 2.0 as well as 3.0 Gy (P < 0.001), while inhibition of JNK pathway increased radiation-induced cell death to a lesser extent. Interestingly combined inhibition of ERK1/2 or AKT pathways did not show additional cell death compared to individual ERK1/2 or AKT inhibition. This indicates that ERK1/2 or AKT mediates radiation resistance through common downstream molecules in B16F10 cells. Conclusions Even without activating mutations in Ras or Braf genes, ERK1/2 and AKT play a critical role in B16F10 cell survival upon radiation exposure and possibly act through common downstream effector/s.

    Genetic variants in SLC16A11 were recently reported to be associated with type 2 diabetes in Mexican and other Latin American populations. The diabetes risk haplotype had a frequency of 50% in Native Americans from Mexico but was rare in Europeans and Africans. In the current study, we analyzed SLC16A11 in 12,811 North American Indians and found that the diabetes risk haplotype, tagged by the rs75493593 A allele, was nominally associated with type 2 diabetes (P = 0.001, odds ratio 1.11). However, there was a strong interaction with BMI (P = 5.1 × 10−7) such that the diabetes association was stronger in leaner individuals. rs75493593 was also strongly associated with BMI in individuals with type 2 diabetes (P = 3.4 × 10−15) but not in individuals without diabetes (P = 0.77). Longitudinal analyses suggest that this is due, in part, to an association of the A allele with greater weight loss following diabetes onset (P = 0.02). Analyses of global gene expression data from adipose tissue, skeletal muscle, and whole blood provide evidence that rs75493593 is associated with expression of the nearby RNASEK gene, suggesting that RNASEK expression may mediate the effect of genotype on diabetes.

  1. Identifying and Measuring the Lifelong Human Capital of “Unskilled” Migrants in the Mexico-US Migratory Circuit

    2014-05-01

    Full Text Available Most human capital and migration studies classify migrants with limited formal education as “unskilled,” despite substantial skills developed through job and life experiences.  Drawing on a binational multi-stage research project that involved interviews with 320 Mexican migrants and return migrants in North Carolina and Guanajuato, Mexico, we identify the lifelong human capital they acquired and transferred throughout their careers and discover that these include not only basic education and English, but also technical and social skills and competences acquired informally on and off the job throughout the course of one’s life.  We further find that the learning and transfer of skills is a lifelong, gendered process, reflecting the different social contexts and jobs in which men and women learn. In this paper we document several mobility pathways associated with the acquisition and transfer of skills across the migratory circuit, including reskilling, occupational mobility, job jumping, and entrepreneurship.Our study has broad implications for the migration policies of both the US and Mexico.  US immigration policy confers preference to “skilled” immigrants who rank high on traditional human capital characteristics, such as education levels and other formal credentials, but limits the entry of “unskilled” migrants, a categorization that ignores the substantial informal skills they bring to US labor markets.  Instead of focusing only on the continued expansion of immigration policy preferences for narrowly defined skilled migrants, the US government needs to consider more carefully what we mean by skilled workers and design fairer and more effective immigration policies that match their abilities to the specific needs of US industry and thereby recognize the economic contributions of all migrants within a lifelong human capital framework. Mexico can also learn from our findings. Between 2005 and 2010 an estimated 1.4 million

    Full Text Available Abstract Background The Blau syndrome (MIM 186580, an autosomal dominant granulomatous disease, was previously mapped to chromosome 16p12-q21. However, inconsistent physical maps of the region and consequently an unknown order of microsatellite markers, hampered us from further refining the genetic locus for the Blau syndrome. To address this problem, we constructed our own high-resolution physical map for the Blau susceptibility region. Results We generated a high-resolution physical map that provides more than 90% coverage of a refined Blau susceptibility region. The map consists of four contigs of sequence tagged site-based bacterial artificial chromosomes with a total of 124 bacterial artificial chromosomes, and spans approximately 7.5 Mbp; however, three gaps still exist in this map with sizes of 425, 530 and 375 kbp, respectively, estimated from radiation hybrid mapping. Conclusions Our high-resolution map will assist genetic studies of loci in the interval from D16S3080, near D16S409, and D16S408 (16q12.1 to 16q13.

    In astrophysics, 4 He( 12 C, 16 O)γ reaction places an important role. At Kyushu University Tandem accelerator Laboratory (KUTL), the measurement of 4 He( 12 C, 16 O)γ cross section is in progress in the energy range of astrophysical nuclear reaction. Since the charge state of product 16 O ions after passing through the gas target is spread and only one charge state can be measured at terminal detector, it is necessary to know the charge state distribution of 16 O ions passing through the He gas target precisely. Here, we report the charge state distribution of the 16 O recoils both experimentally and theoretically. Experimentally, we measured the equilibrium charge state distribution of 16 O ions in the windowless helium gas target with the beam energy of primary 16 O ions at 7.2, 4.5, and 3.45 MeV at KUTL. The measured results showed a Gaussian distribution for the charge state fraction. Theoretically, we proposed a framework for the charge state distribution study. Charge state distribution was computed by solving a set of differential equations including a series of charge exchange cross sections. For the ionization cross section, plane-wave Born approximation was applied and modified by taking target atomic screening as a function of momentum transfer into account. For the capture cross section, continuum distorted wave approximation was applied and the influence of the gas target density was taken into account in the process of electron capture. Using above charge exchange cross sections, the charge state evolution was simulated. According to the equilibrium distribution, we compared the theoretical calculation to the experimental data. After taking into account the density effects in the charge exchange process, the theoretical charge state distributions shows a good agreement with the experimental data. Both experimental and theoretical results are useful to understand the charge fraction of recoil oxygen created via 4 He( 12 C, 16 O)γ reaction

    To determine non-fatal road traffic injuries (NFRTI) prevalence and its distribution in Mexico. Data from ENSANUT Survey 2006 were used. Using simple random sampling, one adult, one adolescent and one child were selected in each household, constituting a final sample of 94,197 representing an N of 102,886,482 people. The dependent variable was the prevalence of road traffic injuries (RTI) during the 12 months prior to the survey. The general accident prevalence was 6.0%; 16.7% corresponded to NFRTI. Men in the 20 to 44 age group living in urban areas and with high socioeconomic status had a higher RTI prevalence (p<0.05). Jalisco, Aguascalientes and Sonora were states with the highest prevalence of RTI, while Guerrero, Michoacan and Oaxaca were those with the lowest. NFRTI are frequent in Mexico and they are concentrated among men in productive ages in urban areas; they are associated with socioeconomic status at the individual level and with the state's development at the population level.

    Residues following 16 O + 12 C fusion were identified by their characteristic γ-rays. For several transitions in 23 Mg, 25 Mg, and 26 Al coincident neutron spectra were measured at six angles. Through use of the evaporation code CASCADE, comparisons were made of these spectra with predictions of the statistical model at five 16 O projectile energies between 43.2 and 56.0 MeV. The results require an excitation energy dependence for the effective radius parameter r 0 which determines the spin cutoff factor

    The total cross sections of the 12C+16O fusion have been experimentally determined at low energies to investigate the role of this reaction during late stellar evolution burning phases. A high-intensity oxygen beam was produced by the 5MV pelletron accelerator at the University of Notre Dame impinging on a thick ultra-pure graphite target. Protons and γ-rays were measured simultaneously in the center-of-mass energy range from 3.64 to 5.01 MeV, using strip silicon and HPGe detectors. Statistical model calculations were employed to interpret the experimental results. A new broad resonance-like structure is observed for the 12C+16O reaction, and a decreasing trend of its S-factor towards low energies is found.

  12. Spectroscopic study of nuclei of the 1f-2p layer by means of (16O,14C) and (16O,12C) transfer reactions

    One-and two-nucleon transfer reactions induced by light projectiles have long been established as powerful spectroscopic tools to test one-and two-nucleon configurations of the wave functions describing the excited states of the residual nucleus A comparatively to the target nuclei A-1 and A-2. As soon as heavy ion beams became available, a further step was made in the experimental study of few-nucleon configurations by increasing the number of transferred particles as well as the variety of reactions leading to the same residual nucleus. It is well known that many theoretical models emphasize the role played by four-nucleon correlations in the microscopic description of deformed states. An experimental study of the reaction mechanism for ( 16 0, 12 C) and ( 16 0, 14 C) has been carried out by measuring angular distributions at several incident energies and excitation functions. A semi-classical description of the experimental results shows the strong influence of nuclear distortions on multi-nucleon-transfer reactions which appear with increasing incident energies. It will be noticed that spectroscopic information concerning the transferred nucleons can be achieved only through a complete finite range DWBA calculation including a microscopic nuclear structure form factor. The relative influence of the kinematic factors and nuclear structure factors on the DWBA cross-sections has been also investigated. The preliminary results on the DWBA analysis of the 54 Fe( 16 0, 12 C) 58 Ni and 48 Ca( 16 O, 14 C) 50 Ti angular distributions are discussed. Finally, ( 16 0, 14 C) and ( 16 0, 12 C) transfer reactions on different 1f-2p shell targets are described

    The {sup 12}C(α,γ){sup 16}O reaction at energies corresponding to the quiescent helium burning in massive stars is regarded as one of the most important processes in nuclear astrophysics. Although this process has being studied for over four decades, our knowledge of its cross section at the energies of interest for astrophysics is still widely unsatisfactory. Indeed, no experimental data are available around 300 keV and in the energy region of astrophysical interest extrapolations are performed using some theoretical approaches, usually R-matrix calculations. Consequently, the published astrophysical factors range from 1 to 288 keVb for S{sub E1}(300) and 7 to 120 keVb for S{sub E2}(300), especially because of the unknown contribution coming from subthreshold resonances. To improve the reliability of these extrapolations, data from complementary experiments, such as elastic and quasi- elastic α scattering on {sup 12}C, α-transfer reactions to {sup 16}O, and {sup 16}N decay are usually included in the analysis. Here the β-delayed α decay of {sup 16}N is used to infer information on the {sup 12}C(α,γ){sup 16}O reaction and a new experimental technique is suggested.

    This paper shows the results attained in energy saving through a project of potable water pumping, which took an investment of $433,043.00 and an internal rate of return of 126%. This project puts into evidence that it is possible to reduce between 15 and 30% of the total invoicing for energy consumption in potable water pumping if an equipment of poor efficiency is replaced by another of high efficiency. The project was requested by the Guanajuato's State Water Comision and the Municipal Bureau of Sewage and Potable Water, with the double intention of reducing the energy consumption along with the corresponding invoicing and incrementing the output of the wells in order to improve the potable water supply. In the site two high efficiency submersible motor-pumps were installed previously to the energy diagnosis that triggered profitable operation results and a convenient invoicing.

The goal of the present study was to determine the prevalence and distribution of HPV types in women from Mexico City. Methods. Our study was conducted in the Clinica de Especialidades de la Mujer de la Secretaría de la Defensa Nacional, Mexico. Random samples were taken from 929 healthy women requesting a cervical Papanicolaou examination. Detection and genotyping of HPV were performed by multiplex PCR, with the HPV4A ACE Screening kit (Seegene. Results. 85 of nine hundred twenty-nine women (9.1% were infected with HPV. Of HPV-positive women, 99% and 1% had high- and low-risk HPV genotypes, respectively. The prevalence of the 16 high-risk (HR HPV types that were screened was 43% : 42% (18 were HPV positive and 14% (16 were HPV positive, which includes coinfection. Multiple infections with different viral genotypes were detected in 10% of the positive cases. Abnormal cervical cytological results were found in only 15.3% of HPV-positive women, while 84.7% had normal cytological results. Conclusions. We found a similar prevalence of HPV to previous studies in Mexico. The heterogeneity of the HPV genotype distribution in Mexico is evident in this study, which found a high frequency of HPV HR genotypes, the majority of which were HPV 18.

    A model-independent method is proposed for the determination of the total reaction cross section from elastic angular distributions. This method based on the generalized optical theorem, was applied to 16 complete elastic angular distributions of the system 12 C + 16 O at energies between E CM =8.55 MeV and E CM = 26.74 MeV. Some of the angular distributions were measured at the Sao Paulo Pelletron Laboratory. Angular distributions measured by the Erlangen and Saclay groups were also used. The reaction cross section is compared with fusion measurements and with σ R obtained by indirect methods. The existence and conditions for the observation of the nuclear forward glory scattering are investigated. (author) [pt

    The effects of temperature on growth, cell toxicity, toxin content, and profile of paralytic shellfish toxins was determined in eight isolates of Gymnodinium catenatum from several localities along the Pacific Coast of Mexico. The isolates were cultivated in modified f/2 media with Se (10(-8) M), and a reduced concentration of Cu (10(-8) M), under a 12 h:12 h day-night cycle with an irradiance of 150 μE m(-2) s(-1). Isolates were progressively adapted for three generations to each of the temperatures (16, 19, 22, 24, 27, 30, and 33 °C). The cultures were grown in 125 mL Erlenmeyer flasks with 60 mL of media and harvested by filtration in late exponential growth. Toxins were analyzed by HPLC with a post-column oxidation and fluorescent detection (FLD). G. catenatum isolates tolerate temperatures between 16 and 33 °C, with maximum growth rates of 0.32 and 0.39 div day(-1) at 21 °C and 24 °C, respectively; maximum cell densities of 4700 and 5500 cells mL(-1) were obtained at 27 and 21 °C, respectively. No effect of toxicity per cell with temperature was observed, varying between 10.10 and 28.19 pgSXTeq cell(-1). Ten saxitoxin analogues were detected in all isolates, observing changes in the toxin profile with temperature. C1/2 toxins decreased from 80% mol at 16 °C to 20% mol at 33 °C, B1/2 toxins increased from 19% mol at 16 °C to 42% mol at 33 °C, and decarbamoyl toxins were more abundant at 21 °C. These results show that G. catenatum isolates from different regions of the Pacific coast of Mexico have a similar response to temperature and that this parameter can modify growth rate, cell density, and toxin profile of the species, particularly the decarbamoyl and sulfocarbamoyl toxins.

  4. Life cycle assessment of electricity generation in Mexico

    International Nuclear Information System (INIS)

    Santoyo-Castelazo, E.; Gujba, H.; Azapagic, A.

    2011-01-01

    This paper presents for the first time a Life Cycle Assessment (LCA) study of electricity generation in Mexico. The electricity mix in Mexico is dominated by fossil fuels, which contribute around 79% to the total primary energy; renewable energies contribute 16.5% (hydropower 13.5%, geothermal 3% and wind 0.02%) and the remaining 4.8% is from nuclear power. The LCA results show that 225 TWh of electricity generate about 129 million tonnes of CO 2 eq. per year, of which the majority (87%) is due to the combustion of fossil fuels. The renewables and nuclear contribute only 1.1% to the total CO 2 eq. Most of the other LCA impacts are also attributed to the fossil fuel options. The results have been compared with values reported for other countries with similar electricity mix, including Italy, Portugal and the UK, showing good agreement. -- Highlights: → This paper presents for the first time a Life Cycle Assessment (LCA) study of electricity generation in Mexico. → 129 million tonnes of CO 2 eq. per year are emitted from 225 TWh of electricity generated per year of which 87% is due to the combustion of fossil fuels. → Coal technologies generate 1094 g CO 2 eq./kWh, heavy fuel oil 964 g CO 2 eq./kWh, and gas 468 g CO 2 eq./kWh; by contrast, nuclear and hydro emit 12 g CO 2 eq./kWh. → Heavy fuel oil contributes most to the life cycle environmental impacts (59-97%). → The results show good agreement with values reported for other countries with similar electricity mix, including Italy, Portugal and the UK.

    Analyses were conducted to estimate lifetime and current prevalence of major depressive disorder (MDD) for four representative cities of Mexico, to identify variables that influence the probability of MDD, and to further describe depression in Mexican culture. A multistage probability sampling design was used to draw a sample of 2,509 adults in four different regions of Mexico. MDD was assessed according to DSM-IV criteria by using the Composite International Diagnostic Interview collected by trained lay interviewers. The prevalence of MDD in these four cities averaged 12.8% for lifetime and 6.1% for the previous 12 months. MDD was highly comorbid with other mental disorders. Women were more likely to have lifetime MDD than were men. Being divorced, separated, or widowed (compared to married or never married) and having experienced childhood trauma were related to higher lifetime prevalence but not to current prevalence. In addition, age and education level were related to current 12-month MDD. Data on the profile of MDD in urban Mexico are provided. This research expands our understanding of MDD across cultures.

    We estimated the potential impact of an investigational 9-valent human papillomavirus (HPV) vaccine (HPVs 6/11/16/18/31/33/45/52/58) in HPV-related cervical disease in Brazil, Mexico, India and China, to help to formulate recommendations on cervical cancer prevention and control. Estimations for invasive cervical cancer (ICC) were based on an international study including 1356 HPV-positive cases for the four countries altogether, and estimations for precancerous cervical lesions were extracted from a published meta-analysis including 6 025 HPV-positive women from the four mentioned countries. Globocan 2012 and 2012 World Population Prospects were used to estimate current and future projections of new ICC cases. Combined proportions of the 9 HPV types in ICC were 88.6% (95%CI: 85.2-91.3) in Brazil, 85.7% (82.3-88.8) in Mexico, 92.2% (87.9-95.3) in India and 97.3% (93.9-99.1) in China. The additional HPV 31/33/45/52/58 proportions were 18.8% (15.3-22.7) in Brazil, 17.6% (14.2-21.2) in Mexico, 11.3% (7.5-16.1) in India and 11.9% (7.5-17.2) in China. HPV6 and 11 single types were not identified in any of the samples. Proportion of the individual 7 high risk HPV types included in the vaccine varied by cytological and histological grades of HPV-positive precancerous cervical lesions. HPV 16 was the dominant type in all lesions, with contributions in low grade lesions ranging from 16.6%(14.3-19.2) in Mexico to 39.8% (30.0-50.2) in India, and contributions in high grade lesions ranging from 43.8% (36.3-51.4) in Mexico to 64.1% (60.6-67.5) in Brazil. After HPV 16, variations in other majors HPV types were observed by country, with an under representation of HPV 18 and 45 compared to ICC. The addition of HPVs 31/33/45/52/58 to HPV types included in current vaccines could increase the ICC preventable fraction in a range of 12 to 19% across the four countries, accounting the 9-types altogether 90% of ICC cases. Assuming the same degree of efficacy of current vaccines, the

    Full Text Available Objective. To estimate calendar of sexual debut in Mexico and its trends using national representative household surveys. Materials and methods. Analysis of five birth cohorts extracted from four national population based household surveys in Mexico (National Health Survey 2000, National Survey on Demographic Dynamics 2009, National Youth Survey 2010, and National Health and Nutrition Survey 2012, using as outcome the proportion of individuals that reported sexual debut before the age of 16 and before the age of 20. Results. Overall, the four analyzed surveys produce consistent results, although some differences were found. While a larger proportion among younger cohorts reported sexual debut before the age of 20, that was not the case for sexual debut before 16 years. Conclusions. While data seems to reflect a relative stable age of sexual debut in Mexico, there is a recent trend to prepone sexual initiation that highlights the need to strengthen comprehensive sexual education and the supply of sexual and reproductive health services that are accessible and friendly to adolescents thus responding to the growing demand from this age group.

    To describe and analyze, utilizing a case study approach, the U.S.- Mexico Border Diabetes Prevention and Control Project, a health research cooperation initiative incorporating the participation of federal, state, and local institutions of both countries. A model of equal representation, participation, consensus, and shared leadership was used, with the participation of more than 130 institutions. A sample of 4 020 people over 18 years of age was obtained by a random, multistage, stratified, clustered design. A questionnaire about diabetes mellitus type 2 (DM2) and health was applied. The statistical analysis took into account the design effect. The prevalence of diagnosed DM2 was 14.9% (95% confidence interval [95% CI]: 12.5-17.6) and the prevalence of diagnosed DM2 adjusted by age was 19.5% (95% CI: 16.8-22.6) on the Mexican side of the border and 16.1% (IC95%: 13.5-19.2) on the U.S. border side. There were differences between the DM2 prevalence and risk factors along the border. The U.S.-Mexico Border Diabetes Prevention and Control Project allowed the border zone between the two countries to be considered, for the first time ever, as a unit for epidemiological research. A shared understanding among all participating institutions and entities of sociopolitical structures and procedures is required for effective border health cooperation initiatives.

    Tuberculosis (TB) is a leading public health problem and a recognized priority for the federal Governments of both Mexico and the United States of America. The objectives of this research, primarily for the four states in the United States that are along the border with Mexico, were to: (1) describe the epidemiological situation of TB, (2) identify TB risk factors, and (3) discuss tuberculosis program strategies. We analyzed tuberculosis case reports collected from 1993 through 2001 by the tuberculosis surveillance system of the United States. We used those data to compare TB cases mainly among three groups: (1) Mexican-born persons in the four United States border states (Arizona, California, New Mexico, and Texas), (2) persons in those four border states who had been born in the United States, and (3) Mexican-born persons in the 46 other states of the United States, which do not border Mexico. For the period from 1993 through 2001, of the 16 223 TB cases reported for Mexican-born persons in the United States, 12 450 of them (76.7%) were reported by Arizona, California, New Mexico, and Texas. In those four border states overall in 2001, tuberculosis case rates for Mexican-born persons were 5.0 times as high as the rates for persons born in the United States; those four states have 23 counties that directly border on Mexico, and the ratio in those counties was 5.8. HIV seropositivity, drug and alcohol use, unemployment, and incarceration were significantly less likely to be reported in Mexican-born TB patients from the four border states and the nonborder states than in patients born in the United States from the four border states (P pulmonary tuberculosis patients who were 18-64 years of age and residing in the four border states, the Mexican-born patients were 3.6 times as likely as the United States-born patients were to have resistance to at least isoniazid and rifampin (i. e., to have multidrug-resistant TB) and twice as likely to have isoniazid resistance

    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.

    Current study aimed to evaluate the performance of bulls (1/2 Purunã vs 1/2 Canchim) slaughtered at two ages and three different weights. One hundred and thirteen bulls were divided into two slaughter ages (16 and 22 months) and three different slaughter weights (light, 422 kg; medium, 470 kg; and heavy, 550 kg). The body weight was higher for bulls slaughtered at 16 months. Daily gain, carcass weight and dressing were higher for bulls slaughtered at 16 months. Feed intake was higher for bulls slaughtered at 22 months although feed efficiency was better for bulls slaughtered at 16 months. Carcass characteristics were better for bulls slaughtered at 16 months. The percentages of muscle, fat and bone and meat characteristics were similar between two slaughter ages. Feed intake and animal performance was lower for lighter animals. Feed conversion and carcass dressing were similar in the three slaughter weights. Muscle percentage was higher for heavier animals but fat and bone percentages were lower. Slaughter weight had no effect on meat characteristics.

    Mexico, the center of origin of maize (Zea mays L.), has taken actions to preserve the identity and diversity of maize landraces and wild relatives. Historically, spatial isolation has been used in seed production to maintain seed purity. Spatial isolation can also be a key component for a strategy to minimize pollen-mediated gene flow in Mexico between transgenic maize and sexually compatible plants of maize conventional hybrids, landraces, and wild relatives. The objective of this research was to generate field maize-to-maize outcrossing data to help guide coexistence discussions in Mexico. In this study, outcrossing rates were determined and modeled from eight locations in six northern states, which represent the most economically important areas for the cultivation of hybrid maize in Mexico. At each site, pollen source plots were planted with a yellow-kernel maize hybrid and surrounded by plots with a white-kernel conventional maize hybrid (pollen recipient) of the same maturity. Outcrossing rates were then quantified by assessing the number of yellow kernels harvested from white-kernel hybrid plots. The highest outcrossing values were observed near the pollen source (12.9% at 1 m distance). The outcrossing levels declined sharply to 4.6, 2.7, 1.4, 1.0, 0.9, 0.5, and 0.5% as the distance from the pollen source increased to 2, 4, 8, 12, 16, 20, and 25 m, respectively. At distances beyond 20 m outcrossing values at all locations were below 1%. These trends are consistent with studies conducted in other world regions. The results suggest that coexistence measures that have been implemented in other geographies, such as spatial isolation, would be successful in Mexico to minimize transgenic maize pollen flow to conventional maize hybrids, landraces and wild relatives.

    Genetic variants in SLC16A11 were recently reported to be associated with type 2 diabetes in Mexican and other Latin American populations. The diabetes risk haplotype had a frequency of 50% in Native Americans from Mexico but was rare in Europeans and Africans. In the current study, we analyzed SLC16A11 in 12,811 North American Indians and found that the diabetes risk haplotype, tagged by the rs75493593 A allele, was nominally associated with type 2 diabetes (P = 0.001, odds ratio 1.11). However, there was a strong interaction with BMI (P = 5.1 × 10(-7)) such that the diabetes association was stronger in leaner individuals. rs75493593 was also strongly associated with BMI in individuals with type 2 diabetes (P = 3.4 × 10(-15)) but not in individuals without diabetes (P = 0.77). Longitudinal analyses suggest that this is due, in part, to an association of the A allele with greater weight loss following diabetes onset (P = 0.02). Analyses of global gene expression data from adipose tissue, skeletal muscle, and whole blood provide evidence that rs75493593 is associated with expression of the nearby RNASEK gene, suggesting that RNASEK expression may mediate the effect of genotype on diabetes. © 2016 by the American Diabetes Association.

    We propose to measure the γ-ray emission probability from excited states above 5 MeV including giant resonance of {sup 16}O and {sup 12}C as a function of excitation energy in 1-MeV step. Here, we measure both the excitation energy (E{sub x}=5-30MeV) at the forward scattering angles (0°-3°) of the {sup 16}O, {sup 12}C (p, p’) reaction using Grand-Raiden Spectrometer and the energy of γ-rays (E{sub γ}) using an array of NaI(Tl) counters. The purpose of the experiment is to provide the basic and important information not only for the γ-ray production from primary neutral-current neutrino-oxygen (-carbon) interactions but also for that from the secondary hadronic (neutron-oxygen and -carbon) interactions.

  3. The future of fuel cell in Mexico in the third millennium

    Science.gov (United States)

    Ramírez-Salgado, J.; Marín-Cruz, J.; Estrada-Martínez, A.

    The warming of the earth due to green house gas emission is mainly produced by CO 2. In Mexico City, 71% of the total harmful emissions is from internal combustion engines of car and buses. Benefits from the use of fuel cells (FCs) in transportation and stationary power generating sectors will achieve satisfactory air quality standards not only in Mexico City but also throughout the country. This paper suggests a scenario for FC technology penetration in Mexico. There are two potential markets for FCs: (i) FC transportation; and (ii) stationary power plant for electrical production. In Mexico City, 3.2 million vehicles are in circulation and represent 19.5% (16.3 million) of the country's total vehicles, and 9.02 million of natural gas users are a potential market for acquiring stationary power generation by FC systems.

The sample included 108 women in the U.S. whose data were obtained from medical chart reviews in a community clinic in Washington, D.C., and 117 women in Mexico who participated in face-to-face interviews in the waiting rooms of primary care community centers in Mexico City. Variables, chosen to match in both countries for comparisons, were: socio-demographics, pregnancy gestation and order, social support, depressive symptoms, personal history of depression, family psychiatric history, and suicidal thoughts. Depressive symptoms were measured using the Center for Epidemiological Studies Depression Scale (CES-D). The prevalence of depressive symptoms was 32.4% for pregnant Latinas and 36.8% for Mexicans (CES-D > or = 16), and 15.7% and 23.9% (CES-D > or = 24), respectively, with no differences between groups. Separate multiple logistic regression analyses showed that for U.S. Latinas: (1) being more educated predicted depressive symptoms (CES-D > or = 16), and (2) second trimester, as compared to first, also predicted symptoms (CES-D > or /= 24). (3) History of suicidal thoughts predicted symptoms in Latinas in the U.S. (CES-D > or = 24) and in Mexico (using both definitions of high symptoms), and (4) living with a partner but not formally married and multi-parous condition predicted symptoms (CES-D > or /= 24) among pregnant Mexicans. A high prevalence of depressive symptoms and significant risk factors during pregnancy were found in Latinas in U.S. and Mexico, suggesting increased risk for postpartum major depression. Implications for screening and interventions are discussed.

    Full Text Available Abstract Background The human 6–16 and ISG12 genes are transcriptionally upregulated in a variety of cell types in response to type I interferon (IFN. The predicted products of these genes are small (12.9 and 11.5 kDa respectively, hydrophobic proteins that share 36% overall amino acid identity. Gene disruption and over-expression studies have so far failed to reveal any biochemical or cellular roles for these proteins. Results We have used in silico analyses to identify a novel family of genes (the ISG12 gene family related to both the human 6–16 and ISG12 genes. Each ISG12 family member codes for a small hydrophobic protein containing a conserved ~80 amino-acid motif (the ISG12 motif. So far we have detected 46 family members in 25 organisms, ranging from unicellular eukaryotes to humans. Humans have four ISG12 genes: the 6–16 gene at chromosome 1p35 and three genes (ISG12(a, ISG12(b and ISG12(c clustered at chromosome 14q32. Mice have three family members (ISG12(a, ISG12(b1 and ISG12(b2 clustered at chromosome 12F1 (syntenic with human chromosome 14q32. There does not appear to be a murine 6–16 gene. On the basis of phylogenetic analyses, genomic organisation and intron-alignments we suggest that this family has arisen through divergent inter- and intra-chromosomal gene duplication events. The transcripts from human and mouse genes are detectable, all but two (human ISG12(b and ISG12(c being upregulated in response to type I IFN in the cell lines tested. Conclusions Members of the eukaryotic ISG12 gene family encode a small hydrophobic protein with at least one copy of a newly defined motif of ~80 amino-acids (the ISG12 motif. In higher eukaryotes, many of the genes have acquired a responsiveness to type I IFN during evolution suggesting that a role in resisting cellular or environmental stress may be a unifying property of all family members. Analysis of gene-function in higher eukaryotes is complicated by the possibility of

    To evaluate the feeding and nutrition conditions and its relation with diabetes mellitus (DM-2) in adult population (> 30 years) a sample belonging to the low socioeconomic stratum of the Mexico City metropolitan area was studied. They were participants in the Second Feeding and Nutrition Survey in the Mexico City metropolitan area. (ENURBAL-2002). Information collected by the ENURBAL 2002 was used in order to evaluate the relationship between some risk factors and diabetes mellitus in adult population of low economical level. Logistical regression analysis was applied. A complete set of 1279 individuals with ages over 30 years was studied. The 9.9% (IC 95% 7.9, 12.4) had been previously diagnosed as diabetics and 3.9% (IC 95% 2.9, 5.4) were not been diagnosed but their glycemia reached diabetic levels. Total diabetes prevalence observed in this study was 13.8% (IC 95% 11.7, 16.3). People with good score on its knowledge about nutrition, as well as high total fat intake, are significant and positively associated with DM-2 (RM = 2.41, IC 95% 1.09, 5.35 and RM = 2.14 IC 95% 1.24, 3.69, respectively). Diabetes mellitus was highly prevalent among adult (> 30 years population) mainly on the lower socioeconomic stratum of Mexico City. This result is important to promote changes in life style that allow to prevent its appearance by modifying the obesigenic environment and changes in the feeding patterns.

  12. Critical role of the 12C(αγ) 16O reaction is stellar evolution and synthesis

    Weaver, T.A.

    1993-01-01

    The extreme sensitivity of stellar evolution and nucleosynthesis to the rate of the 12 C(α,γ) 16 O reaction will be reviewed in the context of models of the complete evolution of 12 to 40 solar mass stars from their birth on the main-sequence to their death in supernova explosions. The nucleosynthesis resulting from integrating the yields of these models over plausible initial stellar mass distributions is found to be in excellent agreement with the observed solar abundances of virtually all intermediate mass isotopes if, and only if, the 12 C(α,γ) 16 O Tate falls within a narrow subset of its currently experimentally allowed range. Factor of 2 to 3 variations in this rate lead to up to a factor of 100 variations in major isotopic production ratios. The importance of further experiments to accurately measure this rate (which is apparently dominated by the contributions of subthreshold resonances) will be stressed

    We have performed a heavy ion radiative capture reaction between two light heavy ions, 12 C and 16 O, leading to 28 Si. The present experiment has been performed below Coulomb barrier energies in order to reduce the phase space and to try to shed light on structural effects. Obtained γ-spectra display a previously unobserved strong feeding of intermediate states around 11 MeV at these energies. This new decay branch is not fully reproduced by statistical nor semi-statistical decay scenarios and may imply structural effects. Radiative capture cross-sections are extracted from the data.

    Full Text Available Nutrient availability has profound influence on development. In the nematode C. elegans, nutrient availability governs post-embryonic development. L1-stage larvae remain in a state of developmental arrest after hatching until they feed. This "L1 arrest" (or "L1 diapause" is associated with increased stress resistance, supporting starvation survival. Loss of the transcription factor daf-16/FOXO, an effector of insulin/IGF signaling, results in arrest-defective and starvation-sensitive phenotypes. We show that daf-16/FOXO regulates L1 arrest cell-nonautonomously, suggesting that insulin/IGF signaling regulates at least one additional signaling pathway. We used mRNA-seq to identify candidate signaling molecules affected by daf-16/FOXO during L1 arrest. dbl-1/TGF-β, a ligand for the Sma/Mab pathway, daf-12/NHR and daf-36/oxygenase, an upstream component of the daf-12 steroid hormone signaling pathway, were up-regulated during L1 arrest in a daf-16/FOXO mutant. Using genetic epistasis analysis, we show that dbl-1/TGF-β and daf-12/NHR steroid hormone signaling pathways are required for the daf-16/FOXO arrest-defective phenotype, suggesting that daf-16/FOXO represses dbl-1/TGF-β, daf-12/NHR and daf-36/oxygenase. The dbl-1/TGF-β and daf-12/NHR pathways have not previously been shown to affect L1 development, but we found that disruption of these pathways delayed L1 development in fed larvae, consistent with these pathways promoting development in starved daf-16/FOXO mutants. Though the dbl-1/TGF-β and daf-12/NHR pathways are epistatic to daf-16/FOXO for the arrest-defective phenotype, disruption of these pathways does not suppress starvation sensitivity of daf-16/FOXO mutants. This observation uncouples starvation survival from developmental arrest, indicating that DAF-16/FOXO targets distinct effectors for each phenotype and revealing that inappropriate development during starvation does not cause the early demise of daf-16/FOXO mutants.

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

  17. Alcohol Consumption and Chronic Liver Disease Mortality in New Mexico and the United States, 1999-2013.

    Current chronic liver disease (CLD) mortality surveillance methods may not adequately capture data on all causes of CLD mortality. The objective of this study was to calculate and compare CLD death rates in New Mexico and the United States by using both an expanded definition of CLD and estimates of the fractional impact of alcohol on CLD deaths. We defined CLD mortality as deaths due to alcoholic liver disease, cirrhosis, viral hepatitis, and other liver conditions. We estimated alcohol-attributable CLD deaths by using national and state alcohol-attributable fractions from the Centers for Disease Control and Prevention's Alcohol-Related Disease Impact application. We classified causes of CLD death as being alcohol-attributable, non-alcohol-attributable, or hepatitis C. We calculated average annual age-adjusted CLD death rates during five 3-year periods from 1999 through 2013, and we stratified those rates by sex, age, and race/ethnicity. By cause of death, CLD death rates were highest for alcohol-attributable CLD. By sex and race/ethnicity, CLD death rates per 100 000 population increased from 1999-2001 to 2011-2013 among American Indian men in New Mexico (67.4-90.6) and the United States (38.9-49.4), American Indian women in New Mexico (48.4-63.0) and the United States (27.5-39.5), Hispanic men in New Mexico (48.6-52.0), Hispanic women in New Mexico (16.9-24.0) and the United States (12.8-13.1), non-Hispanic white men in New Mexico (17.4-21.3) and the United States (15.9-18.4), and non-Hispanic white women in New Mexico (9.7-11.6) and the United States (7.6-9.7). CLD death rates decreased among Hispanic men in the United States (30.5-27.4). An expanded CLD definition and alcohol-attributable fractions can be used to create comprehensive data on CLD mortality. When stratified by CLD cause and demographic characteristics, these data may help states and jurisdictions improve CLD prevention programs.

    To determine the role of Vibrio cholerae as a cause of diarrheal illness in Cancun, Mexico, an investigation was conducted in July and August 1983. Although toxigenic V. cholerae 01 were not found, non-01 V. cholerae were isolated from 22 (16%) of 134 stools from persons with diarrheal illness and none of 22 stools from well persons; 58 (92%) of 63 sewage samples; 12 (86%) of 14 untreated well water samples; a home storage tank for treated water; and 5 (21%) of 24 samples of raw seafood. None of the V. cholerae isolates from patients were toxigenic. The illness occurred mainly in small children, and were characterized principally by diarrhea and abdominal pain. No patient was seriously ill, and all recovered without sequelae. Seven different serotypes of non-01 V. cholerae were isolated from the stool specimens, and Smith serotype 12 accounted for 10 (46%) of the 22 isolates. A matched-pair case-control study found that cases were more likely than controls to have eaten home prepared gelatin (P = 0.03, OR = 5/0) and seafood (P = 0.06, OR = 4/0).

    Cervical cancer, mainly caused by infection with human papillomaviruses (HPVs), is a major public health problem in Mexico. During a study of the prevalence of HPV types in northeastern Mexico, we identified, as expected from worldwide comparisons, HPV-16, 18, 31, and 35 as highly prevalent. It is well known that the genomes of HPV types differ geographically because of evolution linked to ethnic groups separated in prehistoric times. As HPV intra-type variation results in pathogenic differences, we analyzed genomic sequences of Mexican variants of these four HPV types. Among 112 HPV-16 samples, 14 contained European and 98 American Indian (AA) variants. This ratio is unexpected as people of European ethnicity predominate in this part of Mexico. Among 15 HPV-18 samples, 13 contained European and 2 African variants, the latter possibly due to migration of Africans to the Caribbean coast of Mexico. We constructed phylogenetic trees of HPV-31 and 35 variants, which have never been studied. Forty-six HPV-31 isolates from Mexico, Europe, Africa, and the United States (US) contained a total of 35 nucleotide exchanges in a 428-bp segment, with maximal distances between any two variants of 16 bp (3.7%), similar to those between HPV-16 variants. The HPV-31 variants formed two branches, one apparently the European, the other one an African branch. The European branch contained 13 of 29 Mexican isolates, the African branch 16 Mexican isolates. These may represent the HPV-31 variants of American Indians, as a 55% prevalence of African variants in Mexico seems incomprehensible. Twenty-seven HPV-35 samples from Mexico, Europe, Africa, and the US contained 11 mutations in a 893-bp segment with maximal distances between any two variants of only 5 mutations (0.6%), including a characteristic 16-bp insertion/deletion. These HPV-35 variants formed several phylogenetic clusters rather than two- or three-branched trees as HPV-16, 18, and 31. An HPV-35 variant typical for American

    The purposes of the study are to assess the growth status of urban Mexican children living in different geographic areas of the country, to estimate the prevalence of overweight and obesity, and to explore secular trends in body size. Cross-sectional surveys of 293 children 6-11 years from Sonora in the north-west of the country (155 boys, 138 girls), and 356 children 7-12 years from Veracruz on the Gulf Coast (194 boys, 162 girls) were undertaken in 1992 and 1993, respectively. Height and weight were measured; the body mass index (BMI, kg m(-2)) was calculated. Growth status was compared to USA reference data and to samples of Mexican children in 1926 and 1975. The prevalence of overweight (BMI > or = 85th and or = 95th percentile) was estimated. Girls and boys from Sonora and Veracruz do not differ in height, weight and the BMI. Mean heights are at (girls) or below (boys) the medians of USA growth charts, while mean weights are at (boys) or just below (girls) the 75th percentiles at most ages. As a result, mean BMIs are above (boys) and below (girls) the 75th percentiles over the age range studied. The prevalence of overweight and obesity is 40% in boys and 35% in girls, whereas the prevalence of obesity per se is 23% in boys and 17% in girls. Compared to urban Mexican children in the Federal District surveyed in 1926, children in the present sample are taller and heavier, but the secular trend in body weight is more pronounced since the mid-1960s. Heights of the current samples are similar to those of well-off children in Mexico City in the early 1970s, but weights are heavier. The gap in height between well-off and lower socioeconomic status children in different regions of Mexico has been reduced, but there is an increase in the prevalence of overweight and obesity.

    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

    We have measured the FT spectrum of natural OCS from 4800 to 8000 cm-1with a near Doppler resolution and a line-position accuracy between 2 and 8 × 10-4cm-1. For the normal isotopic species16O12C32S, 37 vibrational transitions have been analyzed for both frequencies and intensities. We also report six bands of16O12C34S, five bands of16O13C32S, two bands of16O12C33S, and two bands of18O12C32S. Important effective Herman-Wallis terms are explained by the anharmonic resonances between closely spaced states. As those results complete the study of the Fourier transform spectra of natural carbonyl sulfide from 1800 to 8000 cm-1, a new global rovibrational analysis of16O12C32S has been performed. We have determined a set of 148 molecular parameters, and a statistical agreement is obtained with all the available experimental data.

    Ethyl carbamate (EC) is a recognized genotoxic carcinogen, with widespread occurrence in fermented foods and beverages. No data on its occurrence in alcoholic beverages from Mexico or Central America is available. Samples of agave spirits including tequila, mezcal, bacanora and sotol (n=110), and of the sugarcane spirit cuxa (n=16) were purchased in Mexico and Guatemala, respectively, and analyzed for EC. The incidence of EC contamination was higher in Mexico than in Guatemala, however, concentrations were below international guideline levels (Mexico.

    Full Text Available En México la escasa rotación de cultivos ha afectado la capacidad del suelo para producir, el uso de genotipos de maíz con mayor potencial de rendimiento y sistemas de producción más intensivos ha incrementado la demanda de insumos; lo cual afecta la economía del productor. Para determinar el efecto de los cambios en el precio de los insumos y de los principales factores que explican la oferta de maíz grano en Guanajuato, en este trabajo se estimó un modelo econométrico compuesto por dos ecuaciones de oferta, tres de transmisión de los precios y una identidad para el periodo de 1980 a 2009. Los resultados indican que la oferta de maíz grano en el estado responde inelásticamente ante cambios en el precio medio rural del maíz producido bajo riego y de manera elástica si los cambios se suscitan en el mismo nivel de precio pero de la oferta en temporal, con elasticidades precio-propias de 0.8531 y 1.0604; los cambios en el precio de los insumos que más afectan la oferta estatal son el precio del plaguicida y de la mano de obra, con elasticidades precio-cruzada de -0.6154 y -0.5470; los cambios en el bien competitivo que más le impactan son los registrados en el frijol, con elasticidades precio-cruzada de -0.5489 si es producido bajo riego y de -1.0292 si es producido en temporal. El efecto de transmisión de los precios, indica que el precio al productor de maíz en riego y temporal estatal es influenciado directamente por el precio al mayoreo a razón de 0.79 y 0.80% por cada 1% de cambio en este último, mientras que el costo de transporte y el precio internacional del maíz inciden sobre el precio al mayoreo en el estado a niveles de 0.21 y 0.13% por cada cambio porcentual unitario en éstos.

    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.

    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 novel anti-inflammatory lipid mediator, (4Z,7Z,10Z,12E,14S,16Z,18E,20R)-14,20-dihydroxy-4,7,10,12,16,18-docosahexaenoic acid (1aa), and its three C14,C20 stereoisomers (1ab,ba,bb) were synthesized in a convergent fashion. The carbon backbone of the target compounds was assembled from seven simple fragments by employing two Sonogashira coupling and three SN2 alkynylation reactions. The thus constructed four internal alkynes were chemoselectively reduced to the corresponding (Z)-alkenes by applying a newly developed stepwise protocol: (i) hydrogenation of the three alkynes using Lindlar catalyst and (ii) formation of the dicobalt hexacarbonyl complex from the remaining alkyne and subsequent reductive decomplexation. The synthetic preparation of the stereochemically defined four isomers 1aa,ab,ba,bb permitted determination of the absolute structure of the isolated natural product to be 1aa. Biological testing of the four synthetic 14,20-dihydroxydocosahexaenoic acids disclosed similar anti-inflammatory activities of the non-natural isomers (1ab,ba,bb) and the natural form (1aa).

    In Mexico City there are more than 22 millions of inhabitants (10 in the metropolitan area and 12 in the suburban zone) exposed to drinking water. The local epidemiological authorities recognised that exposure to radon contaminated drinking water is a potential health hazard, as has been considered worldwide. The United States Environmental Protection Agency has proposed a limit of 11.1 Bq l -1 for the radon level in drinking water. In Mexico a maximum contamination level of radon in drinking water has not yet even considered. In this work, a 222 Rn study of drinking water in Mexico City has revealed a range of concentrations from background level to 3.8 Bq l -1 . 222 Rn was calculated using a portable degassing system (AquaKIT) associated with an AlphaGUARD measuring system. Samples from 70 wells of the water system of the south of the Valley Basin of Mexico City and from houses of some other political administrative divisions of Mexico City were taken. (authors)

  15. Tobacco and cancer: epidemiology and new perspectives of prevention and monitoring in Mexico.

    Science.gov (United States)

    Tobacco smoking is causal risk factor of at least 16 different types of cancer. In Mexico, smoking causes 6 035 premature deaths annually of lung cancer and 5 154 from other types. Additionally, 16 408 new smoking- attributable cases are diagnosed, causing high costs in the Mexican health sector. The WHO Framework Convention on Tobacco Control is the global strategy to reduce morbidity and mortality caused by this risk factor. Four more cost-effective strategies to ensure the population benefit are: i) increase tobacco taxes, ii) create 100% smoke-free environments, iii) warn damage through health warnings with pictograms and iv) total ban of advertising and promotion. Mexico is call upon to implement with determination this comprehensive strategy to reduce cancer mortality and assuring the health population.

    The heavy-ion radiative capture "1"2C("1"6O,γ"2"8Si) was measured at the sub-Coulomb barrier bombarding energy E(lab) = 15.7 MeV, which corresponds to the lowest important resonance observed in the "1"2C + "1"6O fusion excitation function. Thanks to combination of the bismuth germanate (BGO) γ-ray array and the 0 degree DRAGON electromagnetic spectrometer at TRIUMF, the γ-decay spectrum from the entrance channel down to the ground state of "2"8Si was measured. Comparisons of the experimental spectrum to γ spectrum extracted from Monte-Carlo simulations of the complete setup suggest a J"π = 2"+ spin-parity assignment to the entrance channel and yield the radiative capture cross section σ(RC) = 0.22 ± 0.04 μb. Combining this present spin assignment with previous data on radiative capture, a J (J + 1) systematics was constructed, and it indicated a moment of inertia commensurate with the "1"2C+"1"6O grazing angular momentum. Strong dipole transitions are observed from the entrance channel to T = 1 states around 11.5 MeV and are found to result from enhanced M1_I_V transitions to states exhausting a large part of the M1 sum rule built on the ground state of "2"8Si. This specific decay was also reported at bombarding energies close to the Coulomb barrier in our previous study of the "1"2C("1"2C,γ"2"4Mg) heavy-ion radiative capture reaction. Similarities between both systems are investigated. (authors)

  17. Compositional and volumetric development of a monogenetic lava flow field: The historical case of Paricutin (Michoacán, Mexico)

    Paricutin volcano is the youngest and most studied monogenetic volcano in the Michoacán-Guanajuato volcanic field (Mexico), with an excellent historical record of its nine years (February 1943 to March 1952) of eruptive activity. This eruption offered a unique opportunity to observe the birth of a new volcano and document its entire eruption. Geologists surveyed all of the eruptive phases in progress, providing maps depicting the volcano's sequential growth. We have combined all of those previous results and present a new methodological approach, which utilizes state of the art GIS mapping tools to outline and identify the 23 different eruptive phases as originally defined by Luhr and Simkin (1993). Using these detailed lava flow distribution maps, the volume of each of the flows was estimated with the aid of pre- and post-eruption digital elevation models. Our procedure yielded a total lava flow volume ranging between 1.59 and 1.68 km3 DRE, which is larger than previous estimates based on simpler methods. In addition, compositional data allowed us to estimate magma effusion rates and to determine variations in the relative proportions of the different magma compositions issued during the eruption. These results represent the first comprehensive documentation of the combined chemical, temporal, and volumetric evolution of the Paricutin lava field and provide key constraints for petrological interpretations of the nature of the magmatic plumbing system that fed the eruption.

    Full Text Available OBJECTIVE: To identify and describe 1 progress achieved thus far in meeting the commitments of the Fourth Millennium Development Goal (MDG 4 in Mexico, mainly the contribution of the Universal Immunization Program (UIP over the last 20 years, and 2 new opportunities for further reducing mortality among children under 5 years old. METHODS: An observational, descriptive, retrospective study was carried out to examine registered causes of death in children under 5 between 1990 and 2010. Indicators were built according to the recommendations of the United Nations. RESULTS: In 2010, deaths among children under 5 decreased 64.3% compared to the baseline (1990 figure. Of the total deaths of the children under 5, the neonatal period was the most affected (52.8%, followed by the 1 to 11 months (30.9%, and the 12 to 59 months (16.2% groups. A 34% overall mortality reduction was observed after the universalization of immunization against influenza, rotavirus, and pneumococcus in children under 5. CONCLUSIONS: Despite a significant reduction in under-5 mortality in Mexico over the last 20 years, largely due to the successes of the UIP, several challenges remain, particularly in improving preventive and curative services during pre- and postnatal care.

    The aim of this study was to evaluate KL-6 and CC16 levels and their correlation with neurodevelopmental outcome among very low birth weight pre-term infants at 12 months corrected age. This prospective cohort study was performed from 2011 to 2013 by enrolling pre-term neonates of gestational age ≤ 32 weeks and birth weight ≤ 1500 g. Serum KL-6 and CC16 levels were determined 7 days after birth and their correlation with neurodevelopment was evaluated using Gesell Mental Developmental Scales. Of the 86 eligible pre-term infants, 63 completed follow-up, of which 15 had bronchopulmonary dysplasia. At 12 months corrected age, 49 infants had favorable outcomes and 14 infants had poor neurodevelopmental outcome. KL-6 levels were higher and CC16 levels were lower in infants with poor neurodevelopmental outcome compared with those infants who had favourable neurodevelopmental outcome. Serum KL-6 levels less than 90.0 ng/ml and CC16 levels greater than 320.0 pg/ml at 7 days of life were found to be predictive of a favourable outcome at 12 months corrected age. These biological markers could predict neurodevelopmental outcome at 12 months corrected age in very low birth weight premature infants, and help the clinician plan early therapeutic interventions to minimize or avoid poor neurodevelopmental outcome.

    Los Alamos National Laboratory (LANL) is a multidisciplinary, multiprogram laboratory with a mission to enhance national military and economic security through science and technology. Its mission is to reduce the nuclear danger through stewardship of the nation's nuclear stockpile and through its nonproliferation and verification activities. An important secondary mission is to promote US industrial competitiveness by working with US companies in technology transfer and technology development partnerships. Los Alamos is involved in partnerships and collaborations with other federal agencies, with industry (including New Mexico businesses), and with universities worldwide. For this report, the reference period is FY 1997 (October 1, 1996, through September 30, 1997) and includes two major impact analysis: the impact of LANL activities on north-central New Mexico and the economic impacts of LANL on the state of New Mexico. Total impact represents both direct and indirect respending by business, including induced effects (respending by households). The standard multipliers used in determining impacts result from the inter-industry, input-output models developed for the three-county region and the state of New Mexico. 5 figs., 12 tabs

    Tritium-Helium-3-Trap (THe-Trap) is a Penning-trap setup dedicated to measure the {sup 3}H to {sup 3}He mass ratio with a relative uncertainty of better than 10{sup -11}. This is 40 times more precise than the currently adopted value and, thus, will help to investigate possible systematic uncertainties of the Karlsruhe Tritium Neutrino experiment (KATRIN). To achieve the desired level of uncertainty, several environmental influences such as atmospheric pressure shifts and magnetic field fluctuations have to be suppressed. With the implemented stabilization system, the relative magnetic field drift could be reduced to a few 10{sup -12}/h for a time span of several weeks. Within the context of this thesis a mass ratio measurement of {sup 12}C{sup 4+} to {sup 16}O{sup 5+} was performed to characterize systematic effects. This measurement yielded a statistical uncertainty of 6.3 x 10{sup -11}, which can easily be improved with more statistics, i.e. a longer measurement time. While the systematic uncertainty for {sup 12}C{sup 4+}-ions were under control at the 10{sup -11} level, the systematic shifts could not be quantified for {sup 16}O{sup 5+} due to poor vacuum conditions. Without these corrections, a systematic uncertainty of 1.2.10{sup -10} could be achieved for the {sup 12}C/{sup 16}O mass ratio measurement.

    Cryptosporidiosis is a parasitic disease caused by Cryptosporidium spp. In immunocompetent individuals, it usually causes an acute and self-limited diarrhea; in infants, infection with Cryptosporidium spp. can cause malnutrition and growth retardation, and declined cognitive ability. In this study, we described for the first time the distribution of C. parvum and C. hominis subtypes in 12 children in Mexico by sequence characterization of the 60-kDa glycoprotein (GP60) gene of Cryptosporidium. Altogether, 7 subtypes belonging to 4 subtype families of C. hominis (Ia, Ib, Id and Ie) and 1 subtype family of C. parvum (IIa) were detected, including IaA14R3, IaA15R3, IbA10G2, IdA17, IeA11G3T3, IIaA15G2R1 and IIaA16G1R1. The frequency of the subtype families and subtypes in the samples analyzed in this study differed from what was observed in other countries. PMID:24755606

  8. Estimating the non-monetary burden of neurocysticercosis in Mexico.

    Directory of Open Access Journals (Sweden)

    Rachana Bhattarai

    Full Text Available BACKGROUND: Neurocysticercosis (NCC is a major public health problem in many developing countries where health education, sanitation, and meat inspection infrastructure are insufficient. The condition occurs when humans ingest eggs of the pork tapeworm Taenia solium, which then develop into larvae in the central nervous system. Although NCC is endemic in many areas of the world and is associated with considerable socio-economic losses, the burden of NCC remains largely unknown. This study provides the first estimate of disability adjusted life years (DALYs associated with NCC in Mexico. METHODS: DALYs lost for symptomatic cases of NCC in Mexico were estimated by incorporating morbidity and mortality due to NCC-associated epilepsy, and morbidity due to NCC-associated severe chronic headaches. Latin hypercube sampling methods were employed to sample the distributions of uncertain parameters and to estimate 95% credible regions (95% CRs. FINDINGS: In Mexico, 144,433 and 98,520 individuals are estimated to suffer from NCC-associated epilepsy and NCC-associated severe chronic headaches, respectively. A total of 25,341 (95% CR: 12,569-46,640 DALYs were estimated to be lost due to these clinical manifestations, with 0.25 (95% CR: 0.12-0.46 DALY lost per 1,000 person-years of which 90% was due to NCC-associated epilepsy. CONCLUSION: This is the first estimate of DALYs associated with NCC in Mexico. However, this value is likely to be underestimated since only the clinical manifestations of epilepsy and severe chronic headaches were included. In addition, due to limited country specific data, some parameters used in the analysis were based on systematic reviews of the literature or primary research from other geographic locations. Even with these limitations, our estimates suggest that healthy years of life are being lost due to NCC in Mexico.

    We proposed six possible reason exchange current mechanism for pion induced non-analog double charge exchange transition on /sup 12/C(π/sup +/, π/sup -/)/sup 12/O(g.s.) and /sup 16/O(π/sup +/, π/sup -/)/sup 16/N/sub e/(g.s.). Under the model, the authors calculated 164 MeV angular distribution. The theoretical results are compared with the existed data and are in a good agreement with the experimental data available. It strongly indicates that the non-analog DCX process is basically a diffractive process through double isobar excitation on a single nucleon and the dominant contribution to the process comes from one of the six diagrams, that is a π/sup +/ collides with a neutron to excite this neutron into an isobar Δ(1232) with charge of one unit; subsequently, the Δ/sup +/ decays to give π/sup +/Δ/sup o/ and then produced π/sup +/ is absorbed by the second target neutron which will be then turned to a proton. Meanwhile the traveling Δ/sup o/ finally decays into π/sup -/P so that the course of the process under consideration here is ended

    Reaction mechanism of the system 13 C+ 16 O- 12 C+ 17 O is investigated with the use of the nucleon molecular-orbital model in the framework of the orthogonalized coupled-reaction-channel (OCRC) theory. The adiabatic potentials obtained are quite different from the diagonal potentials of the original OCRC basis. The Landau-Zener radial coupling explains the backward enhancement of measured differential cross sections of the transfer reaction 13 C( 16 O, 17 O) 12 C. In the OCRC calculation the fusion cross sections of the channel 13 C+ 16 O is enhanced at low bombarding energies, in agreement with the experimental data. (author)

By 1970 the previously pronatalist policy of the government began to shift to one more favorable to family planning. The proximity to the U.S. has made Mexico's history subject to neocolonialism. Until the 1938 nationalization of oil, few of Mexico's decisions were her own. Mexico began to prosper after World War 2, and from 1945-72 the annual growth rate averaged 6%. Mortality decreased while birth rates remained high. Changes in policy have led to dramatic decreases in the birth rate. In 1973 only 11% of all married women were using contraceptives; by 1976 21% were. The 1977-78 birth rate was about 37/1000. Mexico now has a master population plan calling for reduction of the rate of natural increase to 2.5% in 1982 and 1.8% in 1988. The budget or the National Family Planning Coordination was raised in 1979 from 450 million to 700 million pesos (about $32 million). The problem facing Mexico is how to provide employment and education for the more than 40 million people to be born in the next 2 decades. With the increase of women in the work force, 1,200.000 jobs will be needed by the beginning of the 1990s. New oil deposits and the wealth from them are being seen as the solution that will provide the development resources to overcome population problems.

    Preliminary results of a paleomagnetic study on jurassic volcanic rocks (U-Pb 188.8 +/- 3.2Ma) locally interbedded with red beds assigned to the Todos Santos Formation, sampled in the Homoclinal Tectonic Province of the Neogene Fold Belt, Chiapas-Mexico, reveal multi component magnetizations acquired during pre- and post- folding of these rocks. The samples responded well to thermal demagnetization, but not so to AF demagnetization, suggesting that a high coercivity mineral phase like hematite is the main remanence carrier. The post-folding B-component direction of Dec=174.3 Inc=-30.6 (k=46; alpha95=13.6; N=4) represents a recent Tertiary? overprint; while the pre-folding C-component direction of Dec=329.9 Inc=7.8 (k=12.5; alpha95=16.3; N=8) is in agreement with a previously reported small data set for the Todos Santos Formation. When compared to the North American reference direction (Jurassic Kayenta Formation) the observed direction indicates a counterclockwise rotation of 35.9 +/- 16.6 degrees, and moderate north to south latitudinal displacement. If a reference pole from NE North America is used, the amount of counterclockwise rotation and latitudinal displacement are both slightly reduced. If the assumption that Jurassic strata in Chiapas reflect displacement of the Maya Block, then these data are consistent with reconstructions of the Maya Block in the Gulf of Mexico region. Other sites sampled in Jurassic strata suggest that in addition to the interpreted regional rotation, local (vertical-axis) rotations may have affected the region in more recent times.

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

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

    The prevalence of obesity among Mexicans is alarming in both the child and adult populations. The objective of this study was to determine the levels of overweight, obesity and abdominal obesity in pre-school (PS), elementary (ES), and middle high (MHS) public school children from Tijuana. From February to April of 2011, a bietapic random sample was selected by cluster method of 30 PS, 30 ES, and 30 MHS children. And a sample of 30 groups for each level was chosen. Twenty elementary teachers and eight graduate students were trained at one central location on how to take anthropometric measurements using a portable scale, a stadiometer, and a measuring tape to determine weight, height, and waist circumference. Body Mass Index values were computed and compared to age/gender BMI percentiles according to WHO criteria. Waist circumference for-age at the 90th percentile from NHANES III (Mexican-American) was used to define abdominal obesity. The sample was composed of 646 PS children, 961 ES children, and 1,095 MHS children. Their ages ranged from 4- 16 years. Results showed an overall prevalence of overweight and obesity in younger than 5y preschool children (> 2 SD) of 23.1%, in ≥ 5 y PS (> 1 SD) of 33.8%, in ES children of 46.3%, and in MHS children of 41.9%. Abdominal obesity in PS children was 18%, in ES children was 16.7%, and in MHS children was 15.2%. These results warrant immediate and comprehensive actions to prevent a critical public health problem in Mexico. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA.

  1. Family structure and child anemia in Mexico.

    2013-10-01

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

  2. Elimination of Onchocerciasis from Mexico.

    Directory of Open Access Journals (Sweden)

    Mario A Rodríguez-Pérez

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

    We generated novel, effective candidate vaccine against Brucella abortus based on recombinant influenza viruses expressing the Brucella ribosomal protein L7/L12 or outer membrane protein (Omp)-16 from the NS1 open reading frame. The main purpose of this work was to evaluate the safety, immunogenicity and protectiveness of vaccine candidate in laboratory animals. Four recombinant influenza A viral constructs of the subtypes Н5N1 or H1N1 expressing the Brucella proteins L7/L12 or Omp16 were obtained by a reverse genetics method: Flu-NS1-124-L7/L12-H5N1, Flu-NS1-124-Omp16-H5N1, Flu-NS1-124-L7/L12-H1N1 and Flu-NS1-124-Omp16-H1N1. Despite of substantial modification of NS1 gene, all constructs replicated well and were retain their Brucella inserts over five passages in embryonated chicken eggs (CE). Administration of the mono- or bivalent vaccine formulation via prime-boost intranasal (i.n.), conjunctival (c.) or subcutaneous (s.c.) immunization was safe in mice; no deaths, body weight loss or pathomorphological changes were observed over 56 days. Moreover, guinea pigs vaccinated i.n. with vaccine vectors did not shed the vaccine viruses through their upper respiratory tract after the prime and booster vaccination. These findings confirmed the replication-deficient phenotype of viral vectors. The highest antibody response to Brucella antigen was obtained with constructs expressing L7/L12 (ELISA, GMT 242.5-735.0); whereas the highest T-cell immune response- with construct expressing Omp16 (ELISPOT, 337 ± 52-651 ± 45 spots/4×105cells), which was comparable (P > 0.05) to the response induced by the commercial vaccine B. abortus 19. Interestingly, c. immunization appeared to be optimal for eliciting T-cell immune response. In guinea pigs, the highest protective efficacy after challenge with B. abortus 544 was achieved with Omp16 expressing constructs in both monovalent or bivalent vaccine formulations; protective efficacy was comparable to those induced by

    In Mexico City there are more than 22 millions of inhabitants (10 in the metropolitan area and 12 in the suburban zone) exposed to drinking water. The local epidemiological authorities recognised that exposure to radon contaminated drinking water is a potential health hazard, as has been considered worldwide. The United States Environmental Protection Agency has proposed a limit of 11.1 Bq l(-1) for the radon level in drinking water. In Mexico a maximum contamination level of radon in drinking water has not yet even considered. In this work, a (222)Rn study of drinking water in Mexico City has revealed a range of concentrations from background level to 3.8 Bq l(-1). (222)Rn was calculated using a portable degassing system (AquaKIT) associated with an AlphaGUARD measuring system. Samples from 70 wells of the water system of the south of the Valley Basin of Mexico City and from houses of some other political administrative divisions of Mexico City were taken.

    Full Text Available This paper derives from a research project on gender violence to students in middle and high Guanajuato. Surveys, interviews and workshops were applied were performed. During the course of the latter, the high level of youth reported being raped because you do not meet the image that are supposed to have the body that the media tells them to show. Anxiety over what is apparently not conducive indicates serious trouble and sometimes they have attempted suicide. In this sense, we approach the work from the idea that female bodies which are normalized, and where social norms of womanhood (Harcourt, 2011 will also resist. It is in bodies, socio-culturally constructed, where power games enroll. Butler (2010: 93 states that "we are exposed to others, and while this may be a condition of our desire, it also raises the possibility of subjugation and cruelty This results from the fact that the bodies are closely related to each other. through the material, the feel, language and a number of relationships without which we can not survive. "That is, the need for others, for recognition tell us that to meet our needs, we must be as we are told and if we are not then we will not get the recognition and yes cruelty, but as we can not survive and may reactions are self-destruction and violence. What then are the bodies that represent a problem?

    Because of the critical importance of the 12 C/ 16 O ratio resulting from helium burning to the later evolution of massive stars, R-matrix fits have been made to the available angular distribution data from radiative α-capture and elastic α-scattering on 12 C to estimate the total 12 C(α,γ) 16 O rate at stellar energies. Largely primary data, i.e. energy-dependent differential cross sections, are used in the analysis with all relevant partial waves being fitted simultaneously (surface fits). It is shown that while the E1 part of the reaction is well constrained by a recent experiment on the β-delayed α-particle decay of 16 N only upper limits can be placed on the E2 ground state transition which we take conservatively as S E2 (300)<140 keV b. Monte-Carlo simulations were subsequently carried out to explore what kind of future data could lead to better restrictions on SE2(300). We find that improved elastic scattering data may be the best candidate for such restrictions while improving S(300) with new radiative capture data seems to be much more difficult. (orig.)

    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.

    Full Text Available Iatrogenous transmission of Trypanosoma cruziby blood transfusion was suggested as a potential risk by Pellegrino (1949. Seropositive blood donors in Mexico were first reported in 1978, however, limited information is available due to small sampling, the use of heterogeneous serologic assays, and geographically limited studies. A wide survey carried out in 18 out of the 32 states of Mexico, showed a national mean of 1.6% seropositive among 64,969 donors, ranging from 0.2 to 2.8%. In the present study, we have screened 43,048 voluntary blood donors in a period of five years at the Instituto Nacional de Cardiología I. Chávez, a concentration hospital located in Mexico city which serves mainly the metropolitan area and accepts from all over the country. Standardized ELISA and IIF were used to identify seropositive individuals in addition to hemoculture, PCR and standard 12 lead ECG tests that were applied to a group of seropositive patients (29/161. The result showed a seropositivity of 0.37% (161/43,048. From the group of seropositive individuals 40% (12/29 were potential carriers of T. cruzi at the donation time and 5/29 had subclinical ECG abnormalities. Parasitological tests performed in 70 erythrocyte and platelet fractions from seropositive units (70/161 showed negative results. Our findings strongly support T. cruzi screening in the transfusion medicine practice and identify subclinical heart disease among seropositive blood donors.

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

    PKL12/STK16 protein is the first identified mammalian member of a ser/thr kinase subfamily that is conserved across several kingdoms, with a broad expression pattern in murine tissues and cell types. Endogenous STK16 subcellular localization was evaluated by indirect immunofluorescence in NIH/3T3 and NRK cells, demonstrating a Golgi-associated pattern that appears to be independent of signals provided by integrin pathways. When cells were treated with brefeldin A (BFA) or nocodazole, drugs that promote Golgi disorganization, we observed STK16 translocation to the nuclear compartment. Constitutive overexpression of this protein by retroviral vectors also promotes accumulation of STK16 in the nuclear compartment, as shown by subfractionation studies. A kinase-dead STK16 mutant (E202A) was used to demonstrate that both the Golgi association and the nuclear translocation capabilities seem to be independent of the STK16 kinase activity. In addition, we show that STK16 overexpression in several cell lines enhances their capacity to produce and secrete VEGF. To confirm these data in vivo, we injected tumor cells overexpressing STK16 into immunodeficient BALBc/SCID mice. HT1080-derived tumors overexpressing STK16 showed increased volume and number of blood vessels compared to controls.

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

    Aluminium and zinc are known to be the major triggering agents for aggregation of amyloid peptides leading to plaque formation in Alzheimer's disease. While zinc binding to histidine in Aβ (amyloid β) fragments has been implicated as responsible for aggregation, not much information is available on the interaction of aluminium with histidine. In the NMR study of the N-terminal Aβ fragments, DAEFRHDSGYEV (Aβ12) and DAEFRHDSGYEVHHQK (Aβ16) presented here, the interactions of the fragments with aluminium have been investigated. Significant chemical shifts were observed for few residues near the C-terminus when aluminium chloride was titrated with Aβ12 and Aβ16 peptides. Surprisingly, it is nonhistidine residues which seem to be involved in aluminium binding. Based on NMR constrained structure obtained by molecular modelling, aluminium-binding pockets in Aβ12 were around charged residues such as Asp, Glu. The results are discussed in terms of native structure propagation, and the relevance of histidine residues in the sequences for metal-binding interactions. We expect that the study of such short amyloid peptide fragments will not only provide clues for plaque formation in aggregated conditions but also facilitate design of potential drugs for these targets. © 2013 John Wiley & Sons A/S.

    Using 0.72 GeV s -1 pulse π - -meson beam one studied the quasi-elastic knocking out of deuterons and of tritons from 12 C and 16 O nuclei. One derived the quasi-deuteron intranuclear motion pulse distributions, the residual nucleus excitation energy spectra and the effective number of quasi-deuterons. The parameters of quasi-deuteron intranuclear motion pulse distributions are in line with the measurement results for other beams. The effective numbers of quasi-deuterons in nuclei from 6 Li up to 16 O do not depend on the atomic number. One observed knocking out of tritons from the mentioned nuclei enabling to evaluate the cross section of elastic pion-triton backscattering [ru

    Few studies have examined the relation of iron status to diet in populations from developing countries with high levels of iron deficiency and diets of poor quality. The objective was to identify nutrients, dietary constituents, and foods that are associated with better iron status in a rural Mexican population. A prospective cohort study was conducted in rural central Mexico. The subjects were 125 nonpregnant women aged 16-44 y. During the 12 mo before blood collection, food intakes were assessed repeatedly by a combination of dietary recalls, food weighing, and food diaries [mean (+/-SD) days of food intake data: 18.8 +/- 5.9 d]. Hemoglobin, hematocrit, and plasma ferritin were measured at the end of the study. Higher plasma ferritin concentrations were associated with greater intakes of nonheme iron and ascorbic acid after control for age, BMI, breast-feeding, season, and the time since the birth of the last child. Higher ascorbic acid intakes, but not higher intakes of heme and nonheme iron, predicted a lower risk of low hemoglobin and hematocrit values after control for the background variables. Consumption of the alcoholic beverage pulque predicted a lower risk of low ferritin and low hemoglobin values. Seasonal variation in ferritin, hemoglobin, and hematocrit values was observed. Better iron status was associated with greater intakes of foods containing nonheme iron and ascorbic acid. PULQUE:a beverage containing iron, ascorbic acid, and alcohol-may influence the iron status of women in rural central Mexico.

  3. Helping eradicate the medfly from Mexico

    The Mediterranean fruit-fly (Medfly) is a serious pest in Agriculture. It causes damage primarily by its larvae, which feed on the host fruit or vegetable. Agricultural production of about 30 km 2 can be infested in 100 days by the progeny of 1000 females. In Mexico, the Medfly was first observed in 1977. It severely damages the agricultural economy and limits the trade balance and food supplies of the country. Realizing the gravity of the problem, the IAEA, in co-operation with the Governments of Mexico and the United States, implemented a joint pest management programme under the code-name of MOSCAMED. It utilized the Sterile Insect Technique (SIT) on which the Agency has gained considerable experience from its previous involvements in many developing countries. The SIT is technically suitable and environmentally acceptable for Medfly eradication. A factory was built with all areas of SIT expertise. This factory could produce 2 thousand million Medfly eggs in 12 days. The Agency, including its Seibersdorf laboratory, was the primary back-up of the programme. As a result, the northward migration of the fly has been halted and the pest that had infested over 3 million hectares has been eradicated from Mexico as from early 1981

    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

    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.

    Full Text Available A multiplex reverse transcription polymerase chain reaction (RT-PCR assay was developed to simultaneously detect bean common mosaic virus (BCMV, bean common mosaic necrotic virus (BCMNV, and bean golden yellow mosaic virus (BGYMV from common bean leaves dried with silica gel using a single total nucleic acid extraction cetyl trimethyl ammonium bromide (CTAB method. A mixture of five specific primers was used to amplify three distinct fragments corresponding to 272 bp from the AC1 gene of BGYMV as well as 469 bp and 746 bp from the CP gene of BCMV and BCMNV, respectively. The three viruses were detected in a single plant or in a bulk of five plants. The multiplex RT-PCR was successfully applied to detect these three viruses from 187 field samples collected from 23 municipalities from the states of Guanajuato, Nayarit and Jalisco, Mexico. Rates of single infections were 14/187 (7.5%, 41/187 (21.9%, and 35/187 (18.7%, for BGYMV, BCMV, and BCMNV, respectively; 29/187 (15.5% samples were co-infected with two of these viruses and 10/187 (5.3% with the three viruses. This multiplex RT-PCR assay is a simple, rapid, sensitive, and cost-effective method for detecting these viruses in the common bean and can be used for routine molecular diagnosis and epidemiological studies.

  9. U.S.-Mexico energy

    International Nuclear Information System (INIS)

    1991-05-01

    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

    'Full text:' The main sources of electricity generation in Mexico are fossil fuels, mainly gas. At the end of 2013, nearly 50% of total electricity generated in Mexico, was generated by gas and 12% using coal. The Mexican 2012-2026 National Strategy for Energy (ENE-2012) proposes a diversification of generating sources in the electricity sector. Also states an objective indicating that by 2026, at least 35% of the total electricity produced should be by means of non-fossil fuels. Currently, Mexico has one nuclear power plant (Laguna Verde) consisting of two BWR units, with a combined capacity of de 1,610 MW. This power represents 3.08% as total installed capacity in the country, and represents 4.6% of the country's generated electrical energy on 2013. This work analyzes ENE-2012, considering different scenarios for nuclear energy in order to comply with the participation of clean energy sources by 2026. From this analysis we can conclude that nuclear energy should have more participation in the Mexican electricity generation mix for the near future. (author)

    Some evidence suggests that fluoride may be neurotoxic to children. Few of the epidemiologic studies have been longitudinal, had individual measures of fluoride exposure, addressed the impact of prenatal exposures or involved more than 100 participants. Our aim was to estimate the association of prenatal exposure to fluoride with offspring neurocognitive development. We studied participants from the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) project. An ion-selective electrode technique was used to measure fluoride in archived urine samples taken from mothers during pregnancy and from their children when 6-12 y old, adjusted for urinary creatinine and specific gravity, respectively. Child intelligence was measured by the General Cognitive Index (GCI) of the McCarthy Scales of Children's Abilities at age 4 and full scale intelligence quotient (IQ) from the Wechsler Abbreviated Scale of Intelligence (WASI) at age 6-12. We had complete data on 299 mother-child pairs, of whom 287 and 211 had data for the GCI and IQ analyses, respectively. Mean (SD) values for urinary fluoride in all of the mothers (n=299) and children with available urine samples (n=211) were 0.90 (0.35) mg/L and 0.82 (0.38) mg/L, respectively. In multivariate models we found that an increase in maternal urine fluoride of 0.5mg/L (approximately the IQR) predicted 3.15 (95% CI: -5.42, -0.87) and 2.50 (95% CI -4.12, -0.59) lower offspring GCI and IQ scores, respectively. In this study, higher prenatal fluoride exposure, in the general range of exposures reported for other general population samples of pregnant women and nonpregnant adults, was associated with lower scores on tests of cognitive function in the offspring at age 4 and 6-12 y. https://doi.org/10.1289/EHP655.

    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.

    The study of the elastic scattering of 14 C for polarized protons it provides information on the nuclear structure of 15 N. In the Tandem accelerator of the Nuclear Center in collaboration with the University of Notre Dame is carrying out this study to energy between 5.0 and 9.0 MeV in steps of 10 keV. The measures of differential section and vectorial analyzer power are subjected to shift analysis of phase being able to determine the parameters of the excited levels of 15 N that are it angular momentum, parity, level width and elastic width. The details of this experiment are presented in the ACEL-9102 technical report while in this work it was discussed the way in that contributions of 12 C and 16 O are eliminated that are present as impurities in our target of 14 C. At small angles the elastic components of these impurities are shoveled with the elastic of 14 C. In the experiment carried out in the Nuclear Center were take measures of differential section for 6 angles; 35, 45, 55, 65, 145 and 165 using surface barrier detectors. It is observed that it exists shovels at 35, 45, 55 and 65 while at 145 and 165 the 12 C, the 14 C and the 16 O are totally separate. With the purpose of being able to subtract of the elastic of 14 C the proportion of 12 C, it was decided to bombard a target of 12 C leaving the same geometry that had been used to bombard 14 C. With this also carried out the reaction 12 C (p,p) 12 C between 5.0 and 9.0 MeV in steps of 50 keV. Starting from these spectra are the integration (yield) of the elastic of 12 C. (Author)

    Full Text Available Ethyl carbamate (EC is a recognized genotoxic carcinogen, with widespread occurrence in fermented foods and beverages. No data on its occurrence in alcoholic beverages from Mexico or Central America is available. Samples of agave spirits including tequila, mezcal, bacanora and sotol (n=110, and of the sugarcane spirit cuxa (n=16 were purchased in Mexico and Guatemala, respectively, and analyzed for EC. The incidence of EC contamination was higher in Mexico than in Guatemala, however, concentrations were below international guideline levels (<0.15 mg/L. Risk assessment found the Margin of Exposure (MOE in line with that of European spirits. It is therefore unlikely that EC plays a role in high rates of liver cirrhosis reported in Mexico.

    Cross section angular distributions for the /sup 16/O + /sup 58/Ni elastic scattering and the /sup 58/Ni(/sup 16/O, /sup 12/C)/sup 62/Zn- 3.8416 MeV reaction leading to the discrete and continuum states at an incident energy Esub(lab)(/sup 16/O) = 80 MeV have been measured. The eight low-lying single and double energy levels were observed in the energy spectra of the /sup 58/Ni(/sup 16/O, /sup 12/C)/sup 62/Zn reaction. Populations of these levels have the cross sections of 1-200 ..mu..b/sr. The ground state cross section was proved to change with the incident energy by comparing the present data with the other 46 and 60 MeV data. The cross section angular distribution for the ground state transition changes also with the incident energy. The data points for the 46 MeV show a typical bell shape angular distribution. The angular distribution for the 60 MeV reveals a forward peaked and pronounced oscillation pattern, while that for the 80 MeV shows an oscillation damping with the angle and then a monotonous fall on the angle. Optical model parameters were deduced from the best fit to the measurements of the /sup 16/O + /sup 58/Ni elastic scattering. The EFR-DWBA calculations of the (/sup 16/O, /sup 12/C) results were performed with reasonable fits for the cross section angular distributions of observed energy levels. The optical model parameters giving good representations of the ..cap alpha..-transfer data have the property that the real diffuseness parameter has a large value almost equal to the radius parameter. The inclusion of Coulomb correction in the transfer interaction causes a reduction of 0.9 times in cross section, but no change in angular distribution. The dependence of the angular distribution shape on the incident energy can be reproduced by the EFR-DWBA calculation even if only one parameter set is used in the calculation over the wide incident energy range.

    We report a female fetus with sirenomelia with 46,X,t(X;16)(p11.23;p12.3) de novo. Fluorescence in situ hybridization (FISH) with bacterial artificial chromosomes were employed for narrowing down the breakpoint regions. On chromosome 16, the breakpoint was mapped in the region of RP11-453F10 (19 920 640-20 118 153 bp from 16pter). On chromosome X, the breakpoint was mapped in the region of RP11-794A15 (47 333 744-47 524 066 bp from Xpter). This is the first case report of sirenomelia associated with translocations. The abnormal phenotype, associated with a balanced translocation, was caused by deletion or breakage of dosage-sensitive genes of the breakpoint, disruption of an imprinted gene, or uniparental disomy. Although the parental origin of normal 16 and der(16) remained undetermined, this case will provide insight into the pathogenetic mechanism of sirenomelia. © 2011 The Authors.

    Gayón-Vera, Eduardo

    2010-03-01

    On April 24 2007, abortion before 12 weeks became legal in Mexico City. The arguments for this decision were: diminish the maternal morbidity and mortality, avoid a "severe health problem" and accomplish the women's physical, mental and social well being. To analyze the scientific evidences that support or reject this arguments. Retrospective study realized by bibliographic search of electronic data basis and Internet portals of interested groups. Mexico is considered by the World Health Organization, one of the countries in the world with low maternal mortality rates (abortion". In the hospitals of the Mexican Institute of Social Security, maternal deaths as consequence of induced abortions were, approximately, three every year. The evidences used as arguments in favor of abortion come from studies performed in Sub-Saharan African countries, which do not apply to Mexico. The scientific evidences show that induced abortion has important psychological sequels in women, a higher frequency of illegal drug abuse, alcoholism, child abuse, low birth weight in the following pregnancy, greater risk of subsequent miscarriage and greater mortality rate. There are no scientific evidences to support the arguments used for the legal approval of abortion in Mexico City.

    The aim of this study was to perform the complete genome sequence of a swine influenza A H1N2 virus strain isolated from a pig in Guanajuato, México (A/swine/Mexico/GtoDMZC01/2014) and to report its seroprevalence in 86 counties at the Central Bajio zone. To understand the evolutionary dynamics of the isolate, we undertook a phylogenetic analysis of the eight gene segments. These data revealed that the isolated virus is a reassortant H1N2 subtype, as its genes are derived from human (HA, NP, PA) and swine (M, NA, PB1, PB2 and NS) influenza viruses. Pig serum samples were analysed by the hemagglutination inhibition test, using wild H1N2 and H3N2 strains (A/swine/México/Mex51/2010 [H3N2]) as antigen sources. Positive samples to the H1N2 subtype were processed using the field-isolated H1N1 subtype (A/swine/México/Ver37/2010 [H1N1]). Seroprevalence to the H1N2 subtype was 26.74% in the sampled counties, being Jalisco the state with highest seroprevalence to this subtype (35.30%). The results herein reported demonstrate that this new, previously unregistered influenza virus subtype in México that shows internal genes from other swine viral subtypes isolated in the past 5 years, along with human virus-originated genes, is widely distributed in this area of the country. © 2017 Blackwell Verlag GmbH.

    The synthesis and properties are reported of a rare example of a Mn(12) single-molecule magnet (SMM) in truly axial symmetry (tetragonal, I4). [Mn(12)O(12)(O(2)CCH(2)Bu(t))(16)(MeOH)(4)]·MeOH (3·MeOH) was synthesized by carboxylate substitution on [Mn(12)O(12)(O(2)CMe)(16)(H(2)O)(4)]·2MeCO(2)H·4H(2)O (1). The complex was found to possess an S = 10 ground state, as is typical for the Mn(12) family, and displayed both frequency-dependent out-of-phase AC susceptibility signals and hysteresis loops in single-crystal magnetization vs DC field sweeps. The loops also exhibited quantum tunneling of magnetization steps at periodic field values. Single-crystal, high-frequency electron paramagnetic resonance spectra on 3·MeOH using frequencies up to 360 GHz revealed perceptibly sharper signals than for 1. Moreover, careful studies as a function of the magnetic field orientation did not reveal any satellite peaks, as observed for 1, suggesting that the crystals of 3 are homogeneous and do not contain multiple Mn(12) environments. In the single-crystal (55)Mn NMR spectrum in zero applied field, three well-resolved peaks were observed, which yielded hyperfine and quadrupole splitting at three distinct sites. However, observation of a slight asymmetry in the Mn(4+) peak was detectable, suggesting a possible decrease in the local symmetry of the Mn(4+) site. Spin-lattice (T(1)) relaxation studies were performed on single crystals of 3·MeOH down to 400 mK in an effort to approach the quantum tunneling regime, and fitting of the data using multiple functions was employed. The present work and other recent studies continue to emphasize that the new generation of truly high-symmetry Mn(12) complexes are better models for thorough investigation of the physical properties of SMMs than their predecessors such as 1.

    Full text: Absolute elastic cross sections have been measured for targets of 9 Be, 12 C 16 O, 28 Si and 197 Au being bombarded by beams of 13 MeV 6 7 Li and 24 MeV 16 O. The relevant yields were collected simultaneously at 12.450, 16.450, 20.450 and 280. The confidence of a forward elastic scattering method proposed previously to carry out multi-elemental analysis of evaporated liquid samples depends on the precision and accuracy of the cross sections reported in this work.The 24 MeV 16 0 + 197 Au reaction was used to determine the detector solid angles with uncertainties of approximately 3%. Some of the 16 O-beam reactions Some of the 16 O beam reactions have been shown to be consistent with the Rutherford formula predictions at several angles. This allowed us to obtain target thickness independent cross sections for the lithium beam initiated reactions with uncertainties close to 7%. In general, the 6 7 Li-beam reaction cross sections were found not to be consistent with the Coulomb scattering formula. In order to test the internal consistency of our measured cross sections, they were used to determine the elemental densities of several selected targets containing beryllium, carbon, oxygen and silicon. These targets were bombarded with the same beam types and energies used to measure the cross sections and, for every element of interest contained in each target, elemental density values were obtained at some of the scattering angles quoted above. Agreements between some of our results and those of a previous work support the validity of our measurements. (Author)

    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

  6. Thy1.2 YFP-16 transgenic mouse labels a subset of large-diameter sensory neurons that lack TRPV1 expression.

    Directory of Open Access Journals (Sweden)

    Thomas E Taylor-Clark

    Full Text Available The Thy1.2 YFP-16 mouse expresses yellow fluorescent protein (YFP in specific subsets of peripheral and central neurons. The original characterization of this model suggested that YFP was expressed in all sensory neurons, and this model has been subsequently used to study sensory nerve structure and function. Here, we have characterized the expression of YFP in the sensory ganglia (DRG, trigeminal and vagal of the Thy1.2 YFP-16 mouse, using biochemical, functional and anatomical analyses. Despite previous reports, we found that YFP was only expressed in approximately half of DRG and trigeminal neurons and less than 10% of vagal neurons. YFP-expression was only found in medium and large-diameter neurons that expressed neurofilament but not TRPV1. YFP-expressing neurons failed to respond to selective agonists for TRPV1, P2X(2/3 and TRPM8 channels in Ca2+ imaging assays. Confocal analysis of glabrous skin, hairy skin of the back and ear and skeletal muscle indicated that YFP was expressed in some peripheral terminals with structures consistent with their presumed non-nociceptive nature. In summary, the Thy1.2 YFP-16 mouse expresses robust YFP expression in only a subset of sensory neurons. But this mouse model is not suitable for the study of nociceptive nerves or the function of such nerves in pain and neuropathies.

    To analyze tobacco consumption in the last 12 years, its impact on chronic diseases mortality and the potential benefits of fiscal policy in Mexico. Through the analysis of national health surveys (ENSA, ENSANUT), records of mortality and economic surveys between 2000 and 2012, smoking prevalence, chronic diseases mortality and consumption were estimated. In 2012, 9.2% and 19% of Mexican youths and adults were current smokers. Between 2000 and 2012, smoking prevalence did not change. However, the average consumption among adolescents and adults declined whilst the special tobacco tax has being increased. Mortality attributable to tobacco consumption for four diseases was estimated in 60 000 in 2010. Tobacco consumption remains the leading cause of preventable death. Increasing taxes on tobacco products could deter the tobacco epidemic and consequently chronic diseases mortality in Mexico.

    The $^{12}$C$(\\alpha,\\gamma)^{16}$O reaction plays a central role in astrophysics, but its cross section at energies relevant for astrophysical applications is only poorly constrained by laboratory data. The reduced $\\alpha$ width, $\\gamma_{11}$, of the bound $1^-$ level in $^{16}$O is particularly important to determine the cross section. The magnitude of $\\gamma_{11}$ is determined via sub-Coulomb $\\alpha$-transfer reactions or the $\\beta$-delayed $\\alpha$ decay of $^{16}$N, but the latter approach is presently hampered by the lack of sufficiently precise data on the $\\beta$-decay branching ratios. Here we report improved branching ratios for the bound $1^-$ level and for $\\beta$-delayed $\\alpha$ emission. In the case of the $\\beta$-delayed $\\alpha$ branch, we find a $5\\sigma$ deviation from the literature value. With our new branching ratios, the constraints imposed on $\\gamma_{11}$ by the $\\beta\\alpha$-decay and $\\alpha$-transfer data are of similar precision and, for the first time, in good agreement.

    Under some author's opinion the wind is not a periodical phenomenon and therefore it is more reasonable to invest in renewable periodical energies as tides. In this paper we have developed a computer application based in MatLab {sup copyright}, that through the FFT (Fast Fourier Transform) analyzes the variations of wind speed amplitude in the time and frequency domain. The data were sampled every 10 min in the period 2000-2008. The data come from 31 Automatic Meteorological Stations (EMAs), the country of Mexico and correspond one per state. The survey shows the representation of spectral-temporal surfaces to long time intervals, as one year or more and denotes seasonal envelopes that alter the pattern at certain times everyday. As a conclusion, the wind has an important periodical component for the country of Mexico, since the fundamental component of the wind speed represents a frequency of 1/24 h{sup -1} in a very accurate form throughout the time studied. To harness the wind potential of the country of Mexico it should be kept in mind that there is a minimum wind speed between 8 and 16 h and a maximum close to 24 h. (author)

    This paper describes the concentrations of polycyclic aromatic hydrocarbons (PAHs) and aliphatic hydrocarbons (AHs) derived from petroleum in bottled drinking water samples that were collected over 1 year from Mexico City in two bottle sizes (1.5 and 19 L), all brought in supermarkets. The analysis was by gas chromatography with flame ionization detection. -Concentrations of AHs (9.26-1.74 μg/L) were greater than PAHs (20.15-12.78 ng/L). Individual concentrations of PAHs such as fluoranthene, benzo(b)fluoranthene, benzo(k)fluoranthene, indeno(1,2,3-cd)pyrene and benzo(ghi)perylene were comparable with data reported by the World Health Organization (WHO). Total concentrations of PAHs for all samples (BDW1: 12.78 μg/L, BDW2: 16.72 μg/L, BDW3: 14.62 μg/L, BDW4: 20.15 μg/L and BDW5: 13.23 ng/L) were below the maximum permissible European level of 100 ng/L; no regulations exist for AHs although their values were greater than PAHs (BDW1: 3.11 μg/L, BDW2: 8.45 μg/L, BDW3: 1.74 μg/L, BDW4: 4.75 μg/L and BDW5: 9.26 μg/L).

    The ANC of the 2 + (6.92 MeV) and 1 - (7.12 MeV) subthreshold states of 16 O have been extracted from the normalization of 12 C( 6 Li, d) angular distribution to a Finite Range Distorted Wave Born Approximation (FRDWBA) calculation. The theoretical analysis indicates a peripheral reaction and the extracted ANCs are not sensitive to the number of nodes in the bound state potential. The uncertainty from the entrance channel potential is minimized to 8% for the 6.92 and 11% for the 7.12 MeV state if the normalization is performed at the grazing angle. The uncertainty from the exit channel potential at the grazing angle is found to be 10% and 12% respectively for the 7.12 and 6.92 MeV states.

  12. Mexico's nuclear paradox

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

    Objectives To bridge the literature on the effect of father absence, international migration, and social networks on child health, we assess the association between father absence and maternal ratings of child poor health (MCPH). Next we test whether social networks of immediate and extended kin mediate the relationship between fathers' absence and MCPH. Methods Nested logistic regression models predicting MCPH are estimated using the 2013 Social Networks and Health Information Survey, collected in a migrant-sending community in Guanajuato, Mexico. These unique data distinguish among father absence due to migration versus other reasons and between immediate and extended kin ties. Results Descriptive results indicate that 25% of children with migrant fathers are assessed as having poor health, more often than children with present (15.5%) or otherwise absent fathers (17.5%). In the multivariate models, fathers' absence is not predictive of MCPH. However, the presence of extended kin ties for the mother was associated with approximately a 50% reduction in the odds of MCPH. Additionally, mother's poor self-assessed health was associated with increased odds of MCPH while the presence of a co-resident adult lowered the odds of MCPH. In sensitivity analysis among children with migrant fathers, the receipt of paternal remittances lowered the odds of MCPH. Conclusions for Practice Social networks have a direct and positive association with MCPH rather than mediating the father absence-MCPH relationship. The presence of extended kin ties in the local community is salient for more favorable child health and should be considered in public health interventions aimed at improving child health.

    In this work, angular distribution of cross sections have been measured for 12 C( 16 O, 16 O) 12 C at two energies. The measurements were carried out in 0.5 0 intervals between 5 0 -19.5 0 C (lab.) at 140 MeV, 4.5 0 -14.5 0 at 218 MeV. An optical model analysis of these strong structure angular distributions was done. Good fits of the data were obtained using the optical model search code GENOA with a full Woods-Saxon potential form. This yielded parameters subject to considerable ambiguities as it is known to occur for strongly absorbed particles. These ambiguities were explored in detail and it was found that both the real and the imaginary parts present some characteristics that have been found before for the real potential (as Igo relation for continous ambiguities and the fact that potentials with different diffusivities tend to have the same value at the strong absorption radii). It was found, among other results, that the real volume integral, the mean square radius, as well as the total reaction cross section (σsub(r)) cannot be determined unambiguously. A strong correlation was found between σsub(r) and the imaginary diffusivity. A systematic study of how the variation of the potential parameters affects the angular distribution is presented and some features of the diffraction structure of the angular distribution are discussed.

    Inclusive quasielastic neutrino (antineutrino) reactions on 12 C and 16 O at intermediate energies (50< E<400 MeV) are studied to investigate the effects of the nuclear medium on the total cross section and the energy spectrum of the outgoing leptons. The calculations are done in the local density approximation and various nuclear effects like Pauli blocking, Fermi motion, and strong-interaction renormalizations due to the presence of nucleons are taken into account. The corrections due to Coulomb effects are included which have been hitherto neglected in inclusive reactions. The results presented here are applicable to the inclusive reactions with neutrino beams planned to look for neutrino oscillations in the Los Alamos experiments or the experiments with underground detectors looking for atmospheric or solar flare neutrinos

    To evaluate the economic impact of Mexico City's 2008 smoke-free law--The Non-Smokers' Health Protection Law on restaurants, bars and nightclubs. We used the Monthly Services Survey of businesses from January 2005 to April 2009--with revenues, employment and payments to employees as the principal outcomes. The results are estimated using a differences-in-differences regression model with fixed effects. The states of Jalisco, Nuevo León and México, where the law was not in effect, serve as a counterfactual comparison group. In restaurants, after accounting for observable factors and the fixed effects, there was a 24.8% increase in restaurants' revenue associated with the smoke-free law. This difference is not statistically significant but shows that, on average, restaurants did not suffer economically as a result of the law. Total wages increased by 28.2% and employment increased by 16.2%. In nightclubs, bars and taverns there was a decrease of 1.5% in revenues and an increase of 0.1% and 3.0%, respectively, in wages and employment. None of these effects are statistically significant in multivariate analysis. There is no statistically significant evidence that the Mexico City smoke-free law had a negative impact on restaurants' income, employees' wages and levels of employment. On the contrary, the results show a positive, though statistically non-significant, impact of the law on most of these outcomes. Mexico City's experience suggests that smoke-free laws in Mexico and elsewhere will not hurt economic productivity in the restaurant and bar industries.

    The magnitude of Leptospira exposure in rural Mexico is largely unknown. We sought to determine the seroprevalence of Leptospira IgG antibodies in adults in rural Durango, Mexico, and to determine the sociodemographic, behavioral, and housing characteristics of the subjects associated with Leptospira seropositivity. We performed a cross-sectional study in 282 adults living in rural Durango, Mexico. Sera from participants were analyzed for Leptospira IgG antibodies using a commercially available enzyme immunoassay. Seroprevalence association with the characteristics of the subjects was analyzed by bivariate and multivariate analyses. Of the 282 rural subjects (42.91 ± 17.53 years old) studied, 44 (15.6%) had anti-Leptospira IgG antibodies. Seropositivity to Leptospira was not associated with gender, educational level, employment, socioeconomic status, contact with animals or soil, or type of floors at home. In contrast, multivariate analysis showed that Leptospira exposure was associated with national trips (OR = 2.09; 95% CI: 1.05-4.16; P = 0.03) and poor education of the head of the family (OR = 2.96; 95% CI: 1.51-5.78; P = 0.001). We demonstrated serological evidence of Leptospira exposure in adults in rural northern Mexico. The contributing factors associated with Leptospira exposure found in the present study may be useful for optimal planning of preventive measures against Leptospira infection.

    In winter 2011–12 and summer 2012, the U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers, Albuquerque District and the U.S. Fish and Wildlife Service New Mexico Fish and Wildlife Conservation Office in Albuquerque, New Mexico, evaluated the physical characteristics and fish assemblage composition of available mesohabitats over a range of streamflows at 15 sites on the Middle Rio Grande in New Mexico. The fish assemblage of the Middle Rio Grande includes several minnow species adapted to hydrologically variable but seasonably predictable rivers, including theHybognathus amarus (Rio Grande silvery minnow), a federally listed endangered species. Gaining a better understanding of habitat usage by the Rio Grande silvery minnow was the impetus for studying physical characteristics and fish assemblages in the Middle Rio Grande during different streamflow conditions. Data were collected at all 15 sites during winter 2011–12 (moderate streamflow), and a subset was collected at the 13 most downstream sites in summer 2012 (low streamflow). Sites were grouped into four river reaches separated by diversion dams listed in downstream order (names of the diversion dams are followed by short names of the sites nearest each dam in parentheses, listed in downstream order): (1) Cochiti (Peña Blanca), (2) Angostura (Bernalillo, La Orilla, Barelas, Los Padillas), (3) Isleta (Los Lunas I, Los Lunas II, Abeytas, La Joya, Rio Salado), and (4) San Acacia (Lemitar, Arroyo del Tajo, San Pedro, Bosque del Apache I, and Bosque del Apache II). Stream habitat was mapped in the field by using a geographic information system in conjunction with a Global Positioning System. Fish assemblage composition was determined during both streamflow regimes, and fish were collected by seining in each mesohabitat where physical characteristic data (depth, velocity, dominant substrate type and size, and percent embeddedness) and water-quality properties (temperature

    Irritable bowel syndrome (IBS) is recognized as the most frequent functional digestive disorder around the world. In Latin America and Mexico there are few studies in order to demonstrate its real prevalence in general population. To determine the prevalence of IBS in general population from Veracruz City Mexico, using the Rome II criteria. Using basic information given by bureau for planning urban services from Veracruz country, a 10% random population sample was obtained. Subjects between 16-80 years old were interviewed using a questionnaire based on Rome II criteria and a visual analogous scale in order to estimate the negative effect of IBS symptoms on daily activities. We interviewed 459 subjects with a median age of 31.2 +/- 13.6 years old detecting 78 subjects (16.9%) with IBS symptoms: 25 males and 53 females (gender prevalence of 11.3% and 22.1%, respectively). 28.2% of them had IBS with diarrhea, 50% had IBS with constipation and 21.8% alternating bowel movements, diarrhea and constipation. Negative effect of IBS symptoms on daily activities was significant. The prevalence of IBS in open population was 16.9% according to Rome II criteria, being higher in those older than 35 years old. Constipation was the predominant pattern. Further studies should evaluate associated factors of these findings.

    Deportation from the United States for drug offenses is common, yet the consequences of deportation for women drug users are poorly documented. In 2008, in Tijuana, Mexico, we conducted an exploratory qualitative study of migration, deportation, and drug abuse by interviewing 12 Mexican injection-drug-using women reporting U.S. deportation. Women reported heavy drug use before and after deportation, but greater financial instability and physical danger following deportation than when in the United States. We identified an unmet need for health and social services among deported drug-using women, including HIV prevention, drug treatment, physical and mental health services, and vocational training. Binational coordination is needed to help deported women resettle in Mexico.

  12. Elastic scattering of deuterons from hydrogen at 2.0, 1.6 and 1.2 GeV, and search for critical opalescence in inelastic scattering of proton from carbon-12 at 800 MeV

    Large deuteron vector and tensor asymmetries have been measured for the first time at intermediate energies. The polarized deuteron beam whose tensor and vector components were 0.75 and 0.25, respectively, were used at energies of 2.0, 1.6 and 1.2 GeV. The tensor and vector quantities Pyy and Py were extracted from the data obtained within beam polarization normal to the scattering plane, and Pxx was obtained when the polarization was precessed into the scattering plane. Analysis of the data using multiple scattering theory demonstrates the importance of the non-eikonal correction to the Glauber Model and also the sensitivity of the data to double-spin flip components of the NN amplitudes. In another experiment the differential cross section for the 12C(P,P')12C*(15.11 MeV, 1 + T = 1) reaction has been measured at 800 MeV; the range of the angular distribution corresponds to momentum transfers of 0.7 to 2.4 fm -1 (1 to 3.3 mπ). The cross section decreases almost exponentially at large angles; no maximum is observed in the region where nuclear critical opalescence might be expected. The cross sections which measured in parallel to the 15.11 MeV state were for the levels at 11.83 (2 - ), 12.71 (1 + ), 13.35 (2 - ), 16.1 (2 + ) and 16.58 (2 - ) MeV

    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.

    Full Text Available In this paper some preliminary results are presented, obtained by the application of several surveys between secondary school students. The main objective of this research was to quantify the different kinds of violence that could suffer Young female students in this educative level, as well as the relationship among violence living at home, violence living in their colonies and violence living at the school. Violence to women, girls and young ladies is a complex phenomenon and wide spread in Mexican Society, like official statistics reveal; and a good example are warning signs elaborated by the ENDIREH (National Survey over the Dynamic of the Relationships en the Household over 50% of the marriage women have suffer at least one event of gender violence. Violence on girls and young ladies could cause scholar desertion (Ayala,Zapata and Martínez, 2009 and this situation is mortgage for the families because, like Kabeer point out, education Access has a positive effect over daughters and sons. Is well known that women suffer more violence at household, but, women could suffer violence in other kind of places, like in their hometowns and schools. In community level, 40% of the women, who responses the ENDIREH affirmed they have suffer any type of violence; of this last group, 31% has undergo sexual abuse in their community, the rest of the sample (69% has felt intimidated in community environment. In this way, we can talk about women vulnerability. In Guanajuato state, this figure is a little bit lower, due to 35% of women, in the survey, have affirmed they suffer violence in the community environment. In this sense, 13.4% of women in the ENDIREH survey mentioned they have suffered violence at the school; however, this number is lower compared to national levels of violence at the schools, where 15.7% of women affirmed they have been attacked.

    Background: Male genital human papillomavirus (HPV) prevalence and incidence has been reported to vary by geographical location. Our objective was to assess the natural history of genital HPV by country among men with a median of 48 months of follow-up. Methods: Men ages 18-70 years were recruited from United States ( n = 1,326), Mexico ( n = 1,349), and Brazil ( n = 1,410). Genital specimens were collected every 6 months and HPV genotyping identified 37 HPV genotypes. Prevalence of HPV was compared between the three countries using the Fisher exact test. Incidence rates and 95% confidence intervals were calculated. The median time to HPV clearance among men with an incident infection was estimated using the Kaplan-Meier method. Results: The prevalence and incidence of the genital HPV types known to cause disease in males (HPV 16 and 6) was significantly higher among men from Brazil than men from Mexico. Prevalence and incidence of those genital HPV types in the United States varied between being comparable with those of Mexico or Brazil. Although genital HPV16 duration was significantly longer in Brazil ( P = 0.04) compared with Mexico and the United States, HPV6 duration was shortest in Brazil ( P = 0.03) compared with Mexico and the United States. Conclusions: Men in Brazil and Mexico often have similar, if not higher prevalence of HPV compared with men from the United States. Impact: Currently, there is no routine screening for genital HPV among males and while HPV is common in men, and most naturally clear the infection, a proportion of men do develop HPV-related diseases. Men may benefit from gender-neutral vaccine policies. Cancer Epidemiol Biomarkers Prev; 26(7); 1043-52. ©2017 AACR . ©2017 American Association for Cancer Research.

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

    To evaluate animal-caused fatalities in New Mexico using data collected during medicolegal death investigations, including toxicology, survival interval, and circumstances. A retrospective review of the computerized database and hard copies of files from a centralized, statewide medical examiner's office, excluding deaths due to zoonotic diseases and motor vehicle collisions involving animals. Between 1993 and 2004, 63 deaths caused by animals were reported in New Mexico. The majority of decedents were male (46/63, 73%) and non-Hispanic white (33/63, 52%). Horses were the most commonly implicated animals, with 43 (68%) deaths due to a person being thrown from, crushed, dragged, or kicked by a horse. Cattle caused 9 deaths (14%), dogs caused 3 (5%), and venomous animals caused 3, whereas a bear was responsible for 1 death. Ten decedents (16%) had alcohol present at the time of death, and 8 would have been over the legal blood alcohol concentration for driving (0.08%). Ten deaths (16%) were work-related and included deaths of jockeys and ranch workers. The majority of deaths (42/63, 67%) occurred in remote locations, potentially delaying access to treatment. Survival intervals ranged from 1 day to 33 years. Whereas both human and animal behavior can be difficult to predict, a review of animal-caused fatalities investigated by a medical examiner revealed that in many cases, deaths could have been prevented by either the use of protective gear or alterations in human behavior.

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

    2010-03-01

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

    2015-01-01

    Background Leptospirosis is widespread in Mexico, yet the potential distribution and risk of the disease remain unknown. Methodology/Principal Findings We analysed morbidity and mortality according to age and gender based on three sources of data reported by the Ministry of Health and the National Institute of Geography and Statics of Mexico, for the decade 2000–2010. A total of 1,547 cases were reported in 27 states, the majority of which were registered during the rainy season, and the most affected age group was 25–44 years old. Although leptospirosis has been reported as an occupational disease of males, analysis of morbidity in Mexico showed no male preference. A total number of 198 deaths were registered in 21 states, mainly in urban settings. Mortality was higher in males (61.1%) as compared to females (38.9%), and the case fatality ratio was also increased in males. The overall case fatality ratio in Mexico was elevated (12.8%), as compared to other countries. We additionally determined the potential disease distribution by examining the spatial epidemiology combined with spatial modeling using ecological niche modeling techniques. We identified regions where leptospirosis could be present and created a potential distribution map using bioclimatic variables derived from temperature and precipitation. Our data show that the distribution of the cases was more related to temperature (75%) than to precipitation variables. Ecological niche modeling showed predictive areas that were widely distributed in central and southern Mexico, excluding areas characterized by extreme climates. Conclusions/Significance In conclusion, an epidemiological surveillance of leptospirosis is recommended in Mexico, since 55.7% of the country has environmental conditions fulfilling the criteria that favor the presence of the disease.

    Full Text Available La orientación productiva se entiende como las características fundadas en la historia y configuración social y cultural que se distinguen en un contexto regional. En las últimas décadas, por las reformas estructurales en el sector agropecuario y por procesos de intervenciones externas del desarrollo, algunas regiones han modificado su orientación productiva. El objetivo de este artículo es mostrar las tendencias de cambio en la producción animal de la comunidad el Garbanzo, Irapuato, Guanajuato, México, con el fin de ayudar a comprender la dinámica productiva y la influencia de la intervención externa en el contexto local. Para identificar los cambios en la producción animal se realizaron dos estudios transversales, en 2012 y 2015. En ambos estudios se realizaron censos de la población animal y se utilizaron guías de diálogo y observación participante, los cuales abordaron temas como: genética, reproducción, alimentación, manejo, sanidad y aspectos socioeconómicos de las familias. Los resultados mostraron que en este periodo de tiempo la población de cabras se redujo en 28 %, esta tendencia también se observó en el número de caballos y burros. Caso contrario ocurrió con la población de cerdos y bovinos, que incrementaron al 400% y 90%, respectivamente. Debido a los procesos de intervención, los pobladores han cambiado algunos hábitos en relación a la medicina preventiva e higiene animal. Los motivos de estos cambios tienen que ver con la estructura y la edad de los miembros de la familia, lo cual influye en tener una especie menos o más productiva y comercializable.

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

    Ortega-Guerrero, Beatriz; Newton, Anthony J.

    1998-07-01

    In order to aid palaeoenvironmental research of Late Pleistocene and Holocene deposits of central Mexico, tephra layers collected from the sediments of the Texcoco and Chalco sub-basins, in the southern part of the Basin of Mexico, are geochemically characterized and used as stratigraphic markers. The tephra layers range in composition from basaltic andesites to rhyolites and are calc-alkaline. The tephras range in age from >34,000 to ca. 2600 14C yr B.P. New names are used informally to designate correlated tephras. The Tlahuac tephra is present in Chalco, at a depth of 18 m; in the southeastern part of Texcoco, at a depth of around 10 m; and at the Tlapacoya archaeological site, where it had been mistakenly described as basaltic. This basalt-andesite tephra is dated to at least 34,000 14C yr B.P. The Tlapacoya 1 tephra is dated to between 15,020 ± 450 and 14,430 ± 190 yr B.P. and is present in all Chalco sections. The Tlapacoya 2 tephra corresponds to the previously described "pomez gruesa con fragmentos de andesita" (ca. 14,400 yr B.P.) and is present in all Chalco and Texcoco sections. The likely source of these three tephras is the volcano Popocatepetl. Tephra II at Chalco dates to 12,520 ± 135 yr B.P. and correlates with the Upper Toluca Pumice from Nevado de Toluca volcano. These represent the first geochemical glass-shard analysis of tephras from the Basin of Mexico, and so further research is necessary before a reliable tephrochronology can be established.

    To describe the pharmaceutical drug market in Mexico in terms of its size, structure, business' market power, and consumer negotiating power. A descriptive study based on data from the 2004 Economics Census and the reports of IMS Health, Inc. (Norwalk, Connecticut, United States of America). Sales amounts and volumes of Mexico's pharmaceutical companies from 2002-2005 were obtained and the Herfindahl-Hirschman Index (HHI) and its inverse were calculated as indicators of the market's degree of concentration; also, price elasticity was determined by a product index. The total value of the products manufactured by the pharmaceutical sector was 115 billion in 2006 Mexican pesos, of which 99% pertained to companies categorized as large. This amount constituted 1.2% of the national gross domestic product that year (20.0% of the health sector's portion, estimated to be 6.0%) and 3.9% of the total value of manufactured goods. The HHI of Mexico's pharmaceutical market during the study period was about 0.04, albeit with a steady decline, and its inverse decreased from 23 to 26. The price elasticity of pharmaceutical products was minimal (0.007, 0.003, and -0.002). This study constitutes a preliminary description of Mexico's pharmaceutical market, one of the country's most dynamic economic sectors. It confirmed that the market is a rigid oligopoly, and thus supports enactment of firmer regulatory tools to reduce the power of the manufacturers in favor of that of the consumers.

    The aim of this paper is to compare the state of Cardiac Rehabilitation Programs (CRP) in 2009 with 2015. Focus is directed on health care, training of health-providers, research, and the barriers to their implementation. All authors of RENAPREC-2009, and other cardiac rehabilitation leaders in Mexico were requested to participate. These centres were distributed into two groups: RENAPREC-2009 centres that participated in 2015, and the new CRP units. In 2009 there were 14 centres, two of which disappeared and another two did not respond. CRP-units increased by 71% (n=24), and their geographic distribution shows a centripetal pattern. The coverage of CRP-units was 0.02 centres per 100,000 inhabitants. Only 4.4% of eligible patients were referred to CRP, with a rate of 10.4 patients/100,000 inhabitants in 2015. The ratio of Clinical Cardiologists to Cardiac Rehabilitation Specialists was 94:1, and the ratio of Intervention Specialists to cardiac rehabilitation experts was 16:1. Cardiac rehabilitation activities and costs varied widely. Patient dropout rate in phase II was 12%. Several barriers were identified: financial crisis (83%), lack of skilled personnel (67%), deficient equipment (46%), inadequate areas (42%), and a reduced number of operating centres (38%). CRPs in Mexico are still in the process of maturing. Mexican CRP-centres have several strengths, like the quality of the education of the professionals and the multidisciplinary programs. However, the lack of referral of patients and the heterogeneity of procedures are still their main weaknesses. Copyright © 2016 Instituto Nacional de Cardiología Ignacio Chávez.

  1. Total reaction cross section for 12C+16O below the Coulomb barrier

    International Nuclear Information System (INIS)

    Cujec, B.; Barnes, C.A.

    1976-01-01

    The energy dependence of the total reaction cross section, sigma(E), for 12 C+ 16 0 has been measured over the range Esub(c.m.)=4-12 MeV, by detecting γ-rays from the various possible residual nuclei with two large NaI(Tl) detectors placed close to the target. This technique for measuring total reaction cross sections was explored in some detail and shown to yield reliable values for sigma(E). Although the principal emphasis of this work was placed on obtaining reliable cross sections, a preliminary study has been made of the suitability of various methods for extrapolating the cross section to still lower energies. The statistical model provides a good fit with a reasonable value for the strength function, 2 >/ =6.8x10 -2 , over the range Esub(c.m.)=6.5-12 MeV, but predicts cross sections which are much too large for Esub(c.m.)<6.5 MeV. Optical model fits at low energies are especially sensitive to the radius and diffuseness of the imaginary component of the potential and, since these are still poorly known at present, such extrapolations may be wrong by orders of magnitude. A simple barrier penetration model gives a moderately good fit to the data and seems to provide the safest extrapolation to lower energies at the present time. It is clear, however, that our knowledge of the heavy-ion reaction mechanism at low energies is incomplete, and that cross-section measurements at still lower energies are needed to establish the correct procedure for extrapolating heavy-ion reaction cross sections to low energies.

    The objective of this study was to obtain a phenotypic and genotypic profile of Salmonella enterica including multidrug-resistant (MDR) isolates from food-producing animals and clinical isolates, as well as their genetic relatedness in two different States of Mexico (Jalisco and State of Mexico). A total of 243 isolates were evaluated in terms of antimicrobial resistance (AMR) and related genes through a disk diffusion method and PCR respectively; we found 16 MDR isolates, all of them harbouring the bla CMY gene but not qnr genes, these isolates represent less than 10% of the collection. The pulsed-field gel electrophoresis revealed a higher genotypic similitude within isolates of State of Mexico than Jalisco. A low percentage of Salmonella isolates were resistant to relevant antibiotics in human health, nevertheless, the AMR and involved genes were similar despite the different serovars and origin of the isolates. This investigation provided an insight of the current status of AMR of Salmonella isolates in two States of Mexico and pinpoint the genes involved in AMR and their epidemiological relationship, the information could help to determine an adequate therapy in human and veterinary medicine. © 2017 The Society for Applied Microbiology.

    This paper reports that two California utilities have proposed providing natural gas transportation services to Mexico. The arrangement would provide a second U.S. export sales point at the U.S.-Mexico border and perhaps help alleviate an expected surplus of gas pipeline capacity available to California. Mexico currently imports about 200 MMcfd of U.S. gas via pipelines in Texas

    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.

    Streit, G.E.

    1992-01-01

    Mexico City, faces a severe air pollution problem due to a combination of circumstances. The city is in a high mountain basin at a subtropical latitude. The basin setting inhibits dispersion of pollution and contributes to frequent wintertime thermal inversions which further trap pollutants near the surface. The elevation and latitude combine to provide plentiful sunshine which, in comparison to more northern latitudes, is enhanced in the UV radiation which drives atmospheric photochemistry to produce secondary pollutants such as ozone. The Area Metropolitana de la Ciudad de Mexico AMCW is defined to include the 16 delegations of the Federal District (D.F.) and 17 highly urbanized municipalities in the State of Mexico which border the D.F. The 1990 census (XI Censo General de Poblacion y Vivienda de 1990) records that slightly over 15 million people live in the AMCM. There are numerous other nearby communities which are in the airshed region of Mexico City, but which are not included in the definition and population of the AMCM. The Mexico City Air Quality Research Initiative is one project that is examining the complex relationship between air pollution, economic growth, societal values, and air quality management policies. The project utilizes a systems approach including computer modeling, comprehensive measurement studies of Mexico City's air pollutants, environmental chemical reaction studies and socioeconomic analysis. Los Alamos National Laboratory (USA) and the Mexican Petroleum Institute are the designated lead institutions

    Full Text Available Upon starvation or overcrowding, Caenorhabditis elegans interrupts its reproductive cycle and forms a specialised larva called dauer (enduring. This process is regulated by TGF-beta and insulin-signalling pathways and is connected with the control of life span through the insulin pathway components DAF-2 and DAF-16. We found that replacing cholesterol with its methylated metabolite lophenol induced worms to form dauer larvae in the presence of food and low population density. Our data indicate that methylated sterols do not actively induce the dauer formation but rather that the reproductive growth requires a cholesterol-derived hormone that cannot be produced from methylated sterols. Using the effect of lophenol on growth, we have partially purified activity, named gamravali, which promotes the reproduction. In addition, the effect of lophenol allowed us to determine the role of sterols during dauer larva formation and longevity. In the absence of gamravali, the nuclear hormone receptor DAF-12 is activated and thereby initiates the dauer formation program. Active DAF-12 triggers in neurons the nuclear import of DAF-16, a forkhead domain transcription factor that contributes to dauer differentiation. This hormonal control of DAF-16 activation is, however, independent of insulin signalling and has no influence on life span.

    1986-01-01

    New models of chemical evolution of the solar neighborhood have been computed by taking into account the effect of the revised rate of the C-12(alpha, gamma)O-16 reaction on the chemical yields from massive stars, together with the yields from low- and intermediate-mass stars which also include those from Type I supernova explosions (C-deflagration in white dwarfs). In particular, the evolution of C-12, N-14, O-16, Ne-20, Mg-24, Si-28, and Fe-56 has been followed in detail, and their predicted solar absolute abundances as well as their relative ratios, both in the sun and in metal-poor stars, have been compared with the observed ones. It is concluded that a model with the new yields combined with a Salpeter initial mass function, an upper cutoff mass of 100 solar masses (the mass beyond which stars are not contributing to the galactic enrichment), and an upper limiting mass for intermediate-mass stars of the order of 5 solar masses, is in best agreement with the observations. 34 references

    Background: Some evidence suggests that fluoride may be neurotoxic to children. Few of the epidemiologic studies have been longitudinal, had individual measures of fluoride exposure, addressed the impact of prenatal exposures or involved more than 100 participants. Objective: Our aim was to estimate the association of prenatal exposure to fluoride with offspring neurocognitive development. Methods: We studied participants from the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) project. An ion-selective electrode technique was used to measure fluoride in archived urine samples taken from mothers during pregnancy and from their children when 6–12 y old, adjusted for urinary creatinine and specific gravity, respectively. Child intelligence was measured by the General Cognitive Index (GCI) of the McCarthy Scales of Children’s Abilities at age 4 and full scale intelligence quotient (IQ) from the Wechsler Abbreviated Scale of Intelligence (WASI) at age 6–12. Results: We had complete data on 299 mother–child pairs, of whom 287 and 211 had data for the GCI and IQ analyses, respectively. Mean (SD) values for urinary fluoride in all of the mothers (n=299) and children with available urine samples (n=211) were 0.90 (0.35) mg/L and 0.82 (0.38) mg/L, respectively. In multivariate models we found that an increase in maternal urine fluoride of 0.5mg/L (approximately the IQR) predicted 3.15 (95% CI: −5.42, −0.87) and 2.50 (95% CI −4.12, −0.59) lower offspring GCI and IQ scores, respectively. Conclusions: In this study, higher prenatal fluoride exposure, in the general range of exposures reported for other general population samples of pregnant women and nonpregnant adults, was associated with lower scores on tests of cognitive function in the offspring at age 4 and 6–12 y. https://doi.org/10.1289/EHP655 PMID:28937959

    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)

    2015-04-01

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

    We are studying the energy distributions of spallation neutrons produced at 0 deg. by protons of 0.8 GeV up to 1.6 GeV and deuterons of 1.2 and 1.6 GeV with two complementary experimental techniques: the time of flight measurement with tagged incident protons for low energy neutrons (3-400 MeV) and the use of a magnetic spectrometer at high energy (E ≥ 200 MeV). These measurements enable us to measure for the first time the neutron spectra for incident energies higher than 800 MeV. We have compared the double differential cross sections produced with 1.2 GeV protons on several thin targets (Al, Fe, Zr, W, Pb and Th). The neutron production obtained for a lead target is also studied for various energies (0.8 up to 1.6 GeV) and incident particles (p, d). Data are compared with theoretical simulations carried out using the TIERCE system and the intranuclear cascade model of J. Cugnon associated to the decay code of D. Durand. The neutron spectra calculated by using the HETC and MCNP codes, included in TIERCE, are significantly higher than the measured distributions. A better agreement is observed with the results of the Cugnon's cascade model. (author) [fr

    Large deuteron vector and tensor asymmetries were measured for the first time at intermediate energies. The polarized deuteron beam (with tensor and vector components of 0.75 and 0.25, respectively) was used at energies of 2.0, 1.6, and 1.2 GeV. The tensor and vector quantities P/sub yy/ and P/sub y/ were extracted from the data obtained within beam polarization normal to the scattering plane, and P/sub xx/ was obtained when the polarization was precessed into the scattering plane. Analysis of the data using multiple scattering theory demonstrates the importance of the noneikona correction to the Glauber Model and also the sensitivity of the data to double-spin flip components of the NN amplitudes. The differential cross section for the 12 C(p,p') 12 C* (15.11 MeV, 1 + , T=1) reaction was measured at 800 MeV; the range of the angular distribution corresponds to momentum transfers of 0.7 to 2.4 fm -1 (1 to 3.3 m/sub π/). The cross section decreases almost exponentially at large angles; no maximum is observed in the region where nuclear critical opalescence might be expected. Cross sections measured in parallel to the 15.11-MeV state were for the levels at 11.83 (2 - ), 12.71 (1 + ), 13.35 (2 - ), 16.1 (2 + ), and 16.58 (2 - ) MeV. 86 figures 18 tables

    Allergic rhinitis is an inflammatory disorder of the nasal mucosa, characterized by symptoms of itching, rhinorrhea, nasal congestion and sneezing induced by an IgE-mediated response. In Mexico we have reports of prevalence, with fluctuations of 5.5% to 47.7% with the question of rhinitis symptoms the past 12 months. To determine the prevalence of allergic rhinitis in schoolchildren from various states of Mexico. A descriptive study of prevalence in which a questionnaire was applied to preschool, elementary-, middle- and high-school population. It was performed in four cities in four states of Mexico: Puebla, Puebla, Tulancingo, Hidalgo, Tlaxcala, Tlaxcala and Cancun, Quintana Roo. Parents answered questionnaires of preschool and elementary school and middle- and high-school students answered their questionnaires. The study was conducted from June 2014 to January 2015. The instrument used was: questionnaire diagnosis of allergic rhinitis for epidemiological studies. Of the surveys, 8,159 completed questionnaires were obtained, in the city of Puebla: 2,267, Tulancingo, Hidalgo: 2,478, Tlaxcala, Tlaxcala: 2,574, Cancun, Quintana Roo: 840; total male: 4,190 (51%). The overall average rate of prevalence of allergic rhinitis among four states including all respondents ages was 15%. With the use of the questionnaire diagnosis of allergic rhinitis for epidemiological studies in the four cities in four different states, we found a prevalence of allergic rhinitis of 15% in ≥13 yearpopulation and 13% in ≤12 year-old children.

    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

    The burden of cervical cancer caused by human papillomavirus (HPV) is high in Latin America. The suboptimal HPV vaccination coverage in adolescents could be improved by pediatric immunization. HPV vaccination has not yet been reported in girls HPV-16/18 vaccine in 4-6-year-old girls. Healthy girls (randomized 1:1) received either 2 doses of AS04-HPV-16/18 vaccine (HPV group, N=74) or 1 dose of each measles-mumps-rubella and diphtheria-tetanus-acellular-pertussis vaccines (control group, N=74) 6 months apart. We report the safety and serum anti-HPV-16 and anti-HPV-18 antibodies (measured by enzyme-linked immunosorbent assay) up to 6 months postvaccination, that is, month (M) 12. Injection site pain was the most frequently reported solicited local symptom in HPV vaccinees. The incidence of other solicited and unsolicited symptoms after each vaccination was similar between the HPV and control group. Until M12, 1 girl in the HPV group and 2 in the control group reported serious adverse events; all serious adverse events were assessed as unrelated to study vaccines. No potential immune-mediated diseases were identified. All girls seroconverted for both antigens after 2 doses of AS04-HPV-16/18. In initially seronegative girls, anti-HPV-16 geometric mean concentrations were 20080.0 enzyme-linked immunosorbent assay units (EU)/mL at M7 and 3246.5 EU/mL at M12; anti-HPV-18 geometric mean concentrations were 10621.8 EU/mL at M7 and 1216.6 EU/mL at M12. Two-dose vaccination with AS04-HPV-16/18 was well tolerated and induced adequate antibody responses in 4-6-year-old girls.

    Patterns of diversity are scale dependent and beta-diversity is not the exception. Mexico is megadiverse due to its high beta diversity, but little is known if it is scale-dependent and/or taxonomic-dependent. We explored these questions based on the self-similarity hypothesis of beta-diversity across spatial scales. Using geographic distribution ranges of 2 513 species, we compared the beta-diversity patterns of 4 groups of terrestrial vertebrates, across 7 spatial scales (from ~10 km² to 16...

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

    Full Text Available The adoption of new organizational methods is essential for any firm to improve its ability to seize and create new knowledge, which is necessary to develop alternative types of innovations. Hence, the appropriate use of Information and Communication Technologies (ICTs can substantially improve organizational innovation. In this sense, an empirical study of 288 manufacturing SMEs in the Guanajuato region, Mexico, was conducted to determine the influence of ICTs usage on organizational innovation in a developing country. The results obtained through the Structural Equation Modeling demonstrate that the use of ICTs substantially impacts on organizational innovation. Therefore, SMEs should use ICTs effectively and collaboratively with suppliers and customers to meet market trends and improve or innovate their products

    Full Text Available The goal of this study was to use environmental sequencing of 16S rRNA and bop genes to compare the diversity of planktonic bacteria and archaea across ponds with increasing salinity in the Exportadora de Sal (ESSA evaporative saltern in Guerrero Negro, Baja CA S., Mexico. We hypothesized that diverse communities of heterotrophic bacteria and archaea would be found in the ESSA ponds, but that bacterial diversity would decrease relative to archaea at the highest salinities. Archaeal 16S rRNA diversity was higher in Ponds 11 and 12 (370 & 380 g l-1 total salts respectively compared to Pond 9 (180 g l-1 total salts. Both Pond 11 and 12 communities had high representation (47 and 45% of clones respectively by Haloquadratum walsbyi-like (99% similarity lineages. The archaeal community in Pond 9 was dominated (79% by a single uncultured phylotype with 99% similarity to sequences recovered from the Sfax saltern in Tunisia. This pattern was mirrored in bop gene diversity with greater numbers of highly supported phylotypes including many Haloquadratum-like sequences from the two highest salinity ponds. In Pond 9, most bop sequences, were not closely related to sequences in databases. Bacterial 16S rRNA diversity was higher than archaeal in both Pond 9 and Pond 12 samples, but not Pond 11, where a non-Salinibacter lineage within the Bacteroidetes >98% similar to environmental clones recovered from Lake Tuz in Turkey and a saltern in Chula Vista, CA was most abundant (69% of community. This OTU was also the most abundant in Pond 12, but only represented 14% of clones in the more diverse pond. The most abundant OTU in Pond 9 (33% of community was 99% similar to an uncultured gammaproteobacterial clone from the Salton Sea. Results suggest that the communities of saltern bacteria and archaea vary even in ponds with similar salinity and further investigation into the ecology of diverse, uncultured halophile communities is warranted.

    The aim of this study is to analyze a set of socializing agents for sport and physical activities and to establish their relationship with leisure time sport and physical activities behaviors and practice patterns in samples of teenage students with different sociocultural backgrounds. The sample included 2168 students in their first year of secondary education, 423 of them being from Costa Rica, 408 from Mexico, and 1337 from Spain (1052 male students, 1037 female students, and 79 students who did not specify gender) aged 11-16 years old ( M = 12.49; SD = .81). A validated questionnaire with questions about leisure time sport and physical activities and socializing agents was used. Descriptive, inferential, and multinomial logistic regression analyses were carried out with SPSS 17.0 to compare all three countries. Costa Rica had the most active students, best friends' inactivity, and unsupportive parents being the agents predicting inactivity and a low level of sport and physical activities. Mexico has a high dropout rate and inactive students exceed active ones; no agent predicts inactivity or sport and physical activities pattern. Spain has the highest level of sport and physical activities practice, and parents, siblings, and friends are predicting agents of inactivity together with unsupportive parents and friends.

    Mexico has the largest number of clinical cases of actinomycetoma in North and South America. Species originally identified by less specific methods have been recently reclassified as other known species or as new species. To assess, by 16S rRNA gene sequencing and phenotypic methods, the species distribution of 18 human clinical isolates originally identified as N. brasiliensis, some of them isolated between 1947 and 1959 in Mexico City. Clinical isolates came from the Hospital General, "Dr. Manuel Gea Gonzalez", and Instituto Nacional de Diagnóstico y Referencia Epidemiológica (INDRE) in Mexico, D.F. The strains used in this study included 15 clinical strains isolated between 1947 and 1959 that were originally identified as N. brasiliensis and three more strains obtained in 2007 identified as Nocardia spp. The isolates were identified genotypically by sequencing the 16S rRNA gene, and their phenotypic profiles were obtained with the API Coryne(®) system. Antibiotic susceptibility patterns were tested according to the protocol of the Comité de l'antibiogramme de la Société française de microbiologie[4]. According to 16S rRNA gene, sequencing were identified among 18 human clinical isolates as Nocardia farcinica (n=11) and Nocardia brasiliensis (n=7). A high number of the strains were susceptible to the majority of the antibiotics tested. The phenotypic profiles of the strains were quite uniform for N. farcinica and some variability was observed for N. brasiliensis strains. N. farcinica was the most prevalent species identified. Modern methodologies should be applied in clinical laboratories to accurately identify etiological agents. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Childhood acute leukemia cytological features are unknown in Chiapas, Mexico. Defining these features is important because this is a relatively isolated population with high consanguinity index, and these aspects could determine differences in responses to treatment and outcome. Eighty-one childhood acute leukemia cases treated at the Hospital de Especialidades Pediátricas in Chiapas were characterized by morphology, immunophenotype, genotype, initial risk assignment and status at the time of the study. The proportion of leukemic cell types found in this study was B cell, 75.3%; myeloid, 16%; T cell, 3.7% and NK 1.2%. In B cell leukemia, genetic alterations were present in 40.6% of cases and had a specific outcome regardless of initial risk assessment. Cases with MLL gene alteration died within a month from diagnosis. Translocations were present in 17.5% B cases; t(1;19) was present in those with a favorable outcome. The t(12;21) translocation was related to initial remission and midterm relapse and dead. Hyperdiploidy was present in 20% of B cell cases with good outcome. In 38.5%of myeloid cases were translocations and karyotypic abnormalities. Short-term outcome in this group has been poor; 69% have died or abandoned treatment in relapse from 15 days to 37 months after diagnosis. Relative frequency of different types of acute leukemia in patients treated at a tertiary level pediatric hospital in Chiapas, Mexico, was similar to the one found in other parts of the country. Patients' outcome, under a standardized treatment, differs according to the group, the subgroup and the presence and type of genetic alterations.

    The ciliate diversity of Mexican bromeliads is poorly known. We studied the ciliate community of two species of epiphytic tank bromeliads from 48 individuals of Tillandsia heterophylla and four of T. prodigiosa. The bromeliads occurred on over 22 tree host species. Samples were collected during 2009 and 2010 in a mountain cloud forest and in two coffee plantations and in a pine-oak forest. The ciliates were identified in live and protargol preparations. We recorded 61 ciliate species distributed in 39 genera grouped in eight classes. Ten species were frequent in the 52 samples (20 ± 3.2) and Leptopharynx bromeliophilus was the most frequent recorded in 25 samples. Thirty-three species are new for the fauna of Mexico, 24 species have been recorded for the first time in tank bromeliads. The classes Spirotrichea, Oligohymenophorea and Colpodea presented the highest number of species, 16, 14, and 12, respectively. Colpoda was the most species-rich genus being present with six species. A low similarity between areas and seasons was obtained with Jaccard's index. We conclude that the two bromeliads species host a rich ciliate diversity whose knowledge contributes to the question of ciliate distribution and specifically, in tank bromeliads.

    2014-02-01

    Background: Resonances around xα thresholds in light nuclei are recognized to be important in basic aspects of nuclear structure. However, there is scarce experimental information associated with them. Purpose: We study the α-clustering phenomenon in resonant states around the 4α threshold (14.44 MeV) in the 16O nucleus. Method: The 12C(6Li,d )16O reaction was investigated with an unprecedented resolution at a bombarding energy of 25.5 MeV by employing the São Paulo Pelletron-Enge-Spectrograph facility and the nuclear emulsion technique. Results: Several narrow resonances were populated and the energy resolution of 15 keV allows for the separation of doublet states that were not resolved previously. The upper limits for the resonance widths in this region were extracted. The angular distributions of the absolute differential cross section associated with four natural parity quasibound states are presented and compared to distorted wave Born approximation predictions. Conclusions: Narrow resonances not previously reported in the literature were observed. This indicates that the α-cluster structure information in this region should be revised.

  5. Multiple dissociation of 16O, 14N, and 12C at 32.5 MeV/nucleon

    1988-09-01

    An array of 34 fast/slow plastic scintillators has been used to identify fragments from the breakup of 16 O, 14 N, and 12 C projectiles at 32.5 MeV/nucleon, scattered by a Au target. The dissociation of 16 O into as many as five charged particles has been observed. The yields of the different channels correlate approximately with the threshold energy for separation of the projectile into the observed fragments. The excitation spectrum of the primary projectile fragment was deduced from the measured positions and kinetic energies of the individual fragments. These spectra show that, although most of the decomposition proceeds through excitation energies within /approximately/20 MeV of the lower particle-decay thresholds, excitation energies extending up to /approximately/80 MeV can be produced in the primary stage of the reaction. This represents a significant acquisition of energy by the projectile. Calculations of the yields based on a sequence of binary decays have been presented. Reactions in which one or two units of charge are acquired by the projectile were also observed. 25 refs., 10 figs

    Laser absorption techniques for the measurement of isotopologue abundances in gases have been dripping into the geoscientific community over the past decade. In the field of carbon dioxide such instruments have mostly been restricted to measurements of the most abundant stable isotopologues. Distinct advantages of CRDS techniques are non-destructiveness and the ability to resolve isobaric isotopologues. The determination of low-abundance isotopologues is predominantly limited by the linewidth of the probing laser, laser jitter, laser drift and system stability. Here we present first measurements of 16O12C17O abundances using a new type of ultra-precise cavity ring down spectrometer. By the use of Optical Feedback Frequency Stabilization, we achieved a laser line width in the sub-kHz regime with a frequency drift of less than 20 Hz/s. A tight coupling with an ultra-stable ring down cavity combined with a frequency tuning mechanism which enables us to arbitrarily position spectral points (Burkart et al., 2013) allowed us to demonstrate a single-scan (2 minutes) precision of 40 ppm on the determination of the 16O12C17O abundance. These promising results imply that routine, direct, high-precision measurements of 17O-anomalies in CO2 using this non-destructive method are in reach.

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

    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

    To present data on infant and young child feeding practices (IYCFP) in Mexico from the 2012 National Health and Nutrition Survey (ENSANUT 2012) to support the development of public policy. Women 12-49y and children <2y. Indicators of IYCFP suggested by WHO were analyzed by geographic, socioeconomic, participation in food programs and health insurance variables. Median duration of breast-feeding: 10.2mo and 14.4% with exclusive breastfeeding (EBF) <6m. Breastfeeding deteriorated in most vulnerable groups. Decline in EBF<6m 2006-2012 was explained by increases in consumption of formula and other milks (4%) and water (4%). Three-quarters (74%) of 6-11mo infants had minimum food diversity, and it was lower in the most vulnerable. Complementary feeding improved but breastfeeding declined in Mexico. Promotion actions must be integral, coordinated, financed and evaluated, with Federal government leadership and should include the participation of various stakeholders.

  15. Trade in the US and Mexico helps reduce environmental costs of agriculture

    Martinez-Melendez, Luz A.; Bennett, Elena M.

    2016-05-01

    Increasing international crop trade has enlarged global shares of cropland, water and fertilizers used to grow crops for export. Crop trade can reduce the environmental burden on importing countries, which benefit from embedded environmental resources in imported crops, and from avoided environmental impacts of production in their territory. International trade can also reduce the universal environmental impact of food production if crops are grown where they are produced in the most environmentally efficient way. We compared production efficiencies for the same crops in the US and Mexico to determine whether current crop trade between these two countries provides an overall benefit to the environment. Our economic and environmental accounting for the key traded crops from 2010 to 2014 shows that exports to Mexico are just 3% (∼16 thousand Gg) of the total production of these crops in the US, and exports to US represent roughly 0.13% (∼46 Gg) of Mexican total production of the same crops. Yields were higher in US than Mexico for all crops except wheat. Use of nitrogen fertilizer was higher in US than in Mexico for all crops except corn. Current trade reduces some, but not all, environmental costs of agriculture. A counterfactual trade scenario showed that an overall annual reduction in cultivated land (∼371 thousand ha), water use (∼923 million m3), fertilizer use (∼122 Gg; ∼68 Gg nitrogen) and pollution (∼681 tonnes of N2O emissions to the atmosphere and ∼511 tonnes of leached nitrogen) can be achieved by changing the composition of food products traded. In this case, corn, soybeans and rice should be grown in the US, while wheat, sorghum and barley should be grown in Mexico. Assigning greater economic weight to the environmental costs of agriculture might improve the balance of trade to be more universally beneficial, environmentally.

  18. Technology transfer by CDM projects: A comparison of Brazil, China, India and Mexico

    International Nuclear Information System (INIS)

    2009-01-01

    In a companion paper [Dechezlepretre, A., Glachant, M., Meniere, Y., 2008. The Clean Development Mechanism and the international diffusion of technologies: An empirical study, Energy Policy 36, 1273-1283], we gave a general description of technology transfers by Clean Development Mechanism (CDM) projects and we analyzed their drivers. In this paper, we use the same data and similar econometric models to explain inter-country differences. We focus on 4 countries gathering about 75% of the CDM projects: Brazil, China, India and Mexico. Sixty eight percent of Mexican projects include an international transfer of technology. The rates are, respectively, 12%, 40% and 59% for India, Brazil and China. Our results show that transfers to Mexico and Brazil are mainly related to the strong involvement of foreign partners and good technological capabilities. Besides a relative advantage with respect to these factors, the higher rate of international transfers in Mexico seems to be due to a sector-composition effect. The involvement of foreign partners is less frequent in India and China, where investment opportunities generated by fast growing economies seem to play a more important role in facilitating international technology transfers through the CDM. International transfers are also related to strong technology capabilities in China. In contrast, the lower rate of international transfer (12%) in India may be due to a better capability to diffuse domestic technologies

    Using official data, this study analyzed violent deaths (homicide, suicide, events of undetermined intent and deaths due to legal intervention) in Brazil and Mexico in the three-year periods 2002-2004 and 2012-14, the impact of these causes of death on life expectancy in both countries and the role of the different age groups in years of life expectancy lost (YLEL). Abridged life tables were constructed for both countries for both periods. Temporary life expectancy and YLEL between zero and 80 years by selected causes and age groups were calculated for each triennium. The leading cause of YLEL among men was homicide in both periods in Brazil (1.5 years) and in the second period in Mexico (one year). Violent deaths (VD) accounted for around 16% of YLEL in Brazil and 13% in Mexico in 2012-2014. Among women, YLEL due to homicides and suicides showed the greatest relative increase in both countries, although VD accounted for barely 3% of total YLEL. The highest percentage of YLEL due to VDwas found among the 15 to 29 year age groups in both countries and for both sexes. The increase in rates of VD in Mexico, above all among young people, has curbed further increases in life expectancy in recent years, especially among men. Likewise, the high rates of VD in Brazil in both periods have hindered the growth of life expectancy.

The overall objective of this research was to determine the socio-demographic inductive profile of suicide in Mexico. The data on suicides in Mexico were obtained from the National Institute of Statistics and Geography (INEGI in the period from 1990 to 2011. The profile obtained was: suicides committed in Mexico are by males (83.12%, aged between 20 and 24 years (16.85%, singles (42.48%, with primary education (23.11%, with a job (64.17%. Suicides take place at home (68.2%, and the most commonly used methods are hanging, strangulation, and suffocation (75.08%. This socio-demographic profile reveals some factors influencing this antisocial behaviour and some of Mexico’s population risk factors on committing suicide, allowing for the timely implementation of preventive measures.

    WIPP 12 is a borehole drilled in eastern Eddy County, New Mexico, to investigate the stratigraphy, structure and lithology in the WIPP area. WIPP 12 was drilled in section 17, T22S,R31E, between November 9 and December 7, 1978. The hole was drilled to a depth of 2785.8 ft. It encountered from top to bottom, 16.2 ft of sand, 3 ft of Mescalero Caliche and 9.6 ft of the Gatuna Formation, all of Quaternary age; 138.2 ft of the Triassic Santa Rosa Formation, 483 ft of the Dewey Lake Red Beds, 326 ft of the Rustler Formation, 1771.5 ft of the Salado Formation, and 48.3 ft of the Castile Formation, all of Permian age. Cores or cuttings were obtained for the entire hole. A suite of geophysical logs, including neutron gamma and density curves, was run to the full depth of WIPP 12. The borehole demonstrated that the elevation of the top of the Castile is about 160' above the same horizon in ERDA 9. The WIPP is a demonstration facility for the disposal of transuranic (TRU) waste from defense programs. The WIPP will also provide a research facility to investigate the interactions between bedded salt and high level wastes

Thus they are most suitable for enhancing color rendering index and lowering color temperature in phosphor converted white LEDs (pc-WLEDs) with near-UV/blue LED excitation sources. The excitation band edge in the near UV/blue wavelength in the reported phosphor has been attributed to the coordination environment of the transition metal ion (Mo{sup 6+}, W{sup 6+}) and host crystal structure. Furthermore the quantum efficiency of the phosphors has been enhanced by adjusting activator concentration, suitable compositional alloying using substitutional alkaline earth metal cations and charge compensation mechanisms. - Graphical abstract: The charge transfer excitation of orthorhombic Mg{sub 0.6}Ca{sub 2.16}Mo{sub 0.2}W{sub 0.8}O{sub 6}: Eu{sub 0.12}{sup 3+}/Na{sub 0.12}{sup +} is significantly higher than tetragonal CaMoO{sub 4}: Eu{sup 3+} phosphors making Mg{sub 0.6}Ca{sub 2.16}Mo{sub 0.2}W{sub 0.8}O{sub 6}: Eu{sub 0.12}{sup 3+}/Na{sub 0.12}{sup +} prime candidates for fabrication of warm white phosphor-converted LEDs. - Highlights: • LED excitable Mg{sub 0.6}Ca{sub 2.16}Mo{sub 0.2}W{sub 0.8}O{sub 6}: Eu{sub 0.12}{sup 3+}/Na{sub 0.12}{sup +} phosphors were synthesized. • These phosphors are 10 times more intense than CaMoO{sub 4}: Eu{sup 3+} red phosphors. • Their intensity and efficiency were enhanced by materials optimization techniques. • Such techniques include compositional alloying, charge compensation, etc.

    2011-09-01

    This study examines the experiences and opinions of health-care professionals after the legalization of abortion in Mexico City in 2007. Sixty-four semistructured interviews were conducted between 1 December 2007 and 16 July 2008 with staff affiliated with abortion programs in 12 hospitals and 1 health center, including obstetricians/gynecologists, nurses, social workers, key decisionmakers at the Ministry of Health, and others. Findings suggest that program implementation was difficult because of the lack of personnel, space, and resources; a great number of conscientious objectors; and the enormous influx of women seeking services, which resulted in a work overload for participating professionals. The professionals interviewed indicate that the program improved significantly over time. They generally agree that legal abortion should be offered, despite serious concerns about repeat abortions. They recommend improving family planning campaigns and post-procedure contraceptive use, and they encourage the opening of primary health-care facilities dedicated to providing abortion services.

    2009-10-01

    New Mexico (NM) has the highest rate of non-firearm-related homicide in the USA and ranks 20th in firearm-related homicides. Because non-firearm-related homicides are inadequately described in the literature, characterisation of non-firearm-related homicide victims will enhance efforts to reduce homicides. Homicide victims were identified through the Office of the Medical Investigator. Age-specific and age-adjusted homicide death rates were calculated for 2001-3 by sex and race/ethnicity, and associations between covariates and non-firearm-related homicide were measured. Non-firearm-related homicides comprised 33% of US homicide victims, 47% of NM homicide victims, and 74% of NM American Indian (AI) homicide victims. Of 212 NM non-firearm-related homicide victims, 37% had been beaten, 32% had been stabbed, and 12% had been strangled. Females comprised 30% of non-firearm-related homicide victims and 18% of firearm-related homicide victims. A blood alcohol concentration (BAC) >or=0.08 mg/dl was detected among 43% of non-firearm-related (61% of AI) and 33% of firearm-related (50% of AI) homicide victims. Non-firearm-related homicide rates were highest among AI men aged 25-34 years (31/100,000). Non-firearm-related homicide victims were more likely than firearm-related victims to be AI (adjusted odds ratio (AOR) 4.20; 95% CI 2.16 to 8.16) and female (AOR 2.05; 95% CI 1.27 to 3.31), and to have had a BAC >or=0.08 mg/dl (AOR 1.65; 95% CI 1.08 to 2.52). Homicide-prevention efforts among AIs in NM should focus on non-firearm-related homicides. The association between excessive drinking and non-firearm-related homicide should be further characterised. Continued surveillance for non-firearm-related homicides will assist these efforts.

The excitation functions and the angular distributions were measured on the reactions 12 C( 12 C, 8 Besub(g,s,)) 16 Osub(g,s,), 24 Mg( 12 C, α) 32 S and 9 Be ( 12 C, 8 Besub(g,s,)) 13 Csub(g,s,). Sub-Coulomb resonances were observed in all systems and the contribution of the 12 Csub(2nd)*(0 + , 7.65 MeV) state is proposed. (author)

    Full Text Available En el presente estudio se determinó la morfología y la composición proteica de los cristales de las cepas LBIT-499 y LBIT-504 de B. thuringiensis, ambas nativas de Guanajuato, México. La primera mostró sólo cristales bipiramidales mientras que la segunda presentó cristales tanto bipiramidales como cúbicos. Estos cristales estuvieron compuestos de proteínas de aproximadamente 130 y 60 kDa, respectivamente. En ambas cepas, además de la LBIT-500 y LBIT-544, se detectó una gran variedad de genes cry1. En éstas últimas se encontraron los genes cry2A y cry2B, en la LBIT- 504 sólo el cry2B y en la LBIT-499 no se detectó ningún cry2. This report revealed the crystal morphology and protein composition of strains LBIT-499 and LBIT-504 of B. thuringiensis, native to Guanajuato, Mexico. LBIT-499 showed only bipyramidal crystals, while LBIT-504 showed both bipyramidal and cubical crystals. These crystals were composed by proteins of ca. 130 and 60 kDa, respectively. Both strains as well as LBIT-500 and LBIT-544, showed a great variety of cry1 genes, while cry2A and cry2B were identified in LBT-500 and LBIT-544, LBIT-504 showed only the cry2B gene, and no cry2 was detected in LBIT-499.

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

    Full Text Available OBJECTIVE: To assess the safety and immune responses induced by a 13-valent pneumococcal conjugate vaccine (PCV13 after immunization of infants in Mexico. METHODS: PCV13 was given with other routine childhood vaccinations to 225 infants in Mexico at ages 2, 4, 6, and 12 months. RESULTS: The proportions of subjects achieving immunoglobulin G (IgG concentrations ≥0.35 µg/mL after the infant series and toddler dose were ≥93.1% and ≥96.7%, respectively, for all 13 serotypes. The serotype-specific pneumococcal IgG geometric mean concentrations after the infant series and toddler dose ranged from 1.18 to 9.13 µg/mL and from 1.62 to 15.41 µg/mL, respectively. The most common local reaction and systemic event after each dose were tenderness and irritability, respectively. Most fever was mild; no fever >40.0°C (i.e., severe was reported. One subject withdrew because of Kawasaki disease 5 days after the first dose of vaccines, but this condition was not considered related to PCV13. CONCLUSIONS: Overall, PCV13 administered with routine pediatric vaccines was immunogenic and safe in healthy infants in Mexico.

    The aim of this paper is to describe the early stages of Mexican nuclearization that took place in contact with radioisotopes. This history requires a multilayered narrative with an emphasis in North-South asymmetric relations, and in the value of education and training in the creation of international asymmetrical networks. Radioisotopes were involved in exchanges with the United States since the late 1940s, but also with Canada. We also describe the context of implementation of Eisenhower's Atoms for Peace initiative in Mexico that opened the door to training programs at both the Comisión Nacional de Energía Nuclear and the Universidad Nacional Autónoma de México. Radioisotopes became the best example of the peaceful applications of atomic energy, and as such they fitted the Mexican nuclearization process that was and still is defined by its commitment to pacifism. In 1955 Mexico became one of the 16 members of the atomic fallout network established by the United Nations. As part of this network, the first generation of Mexican (women) radio-chemists was trained. By the end of the 1960s, radioisotopes and biological markers were being produced in a research reactor, prepared and distributed by the CNEN within Mexico. We end up this paper with a brief reflection on North-South nuclear exchanges and the particularities of the Mexican case.

    The aim of this study was to determine the prevalence and species composition of helminths in commensal rodents captured inside private residences in the city of Villahermosa in Tabasco, Mexico. Trapping was performed at each house for three consecutive nights from October to December 2015. Fifty commensal rodents were captured: 23 Rattus norvegicus, 16 Mus musculus and 11 Rattus rattus. Rodents were transported alive to the laboratory and held in cages until they defecated. Feces were analyz...
