    Full Text Available El objetivo general fue determinar la capacidad de carga turística (CCT que puede realizar diariamente el Parque Natural Chankanaab, destino masivo para los excursionistas de cruceros que arriban a la isla de Cozumel, México. La hipótesis estableció que la CCT ha sido superada en las temporadas vacacionales. Se aplicó el método de Cifuentes et al. durante 2011, que analiza aspectos físicos, ecológicos y administrativos. Se determinó que la CCT está restringida por la infraestructura del Parque y ha sido rebasada ocasionalmente en temporada alta. Para lograr un aprovechamiento sustentable de las ANP, el método requiere incorporar el área de influencia, las dimensiones social y económica de la comunidad anfitriona, así como la percepción de los visitantes, para lo cual se propone un modelo de aprovechamiento turístico sustentable para las ANP.

    2006-12-01

    Potential insecticide-resistance mechanisms were studied with the use of biochemical assays in Aedes aegypti (L.) collected from 5 municipalities representing the north part of Quintana Roo: Benito Juarez, Cozumel, Isla Mujeres, Lazaro Cardenas, and Solidaridad. The activities of alpha and beta esterases, mixed-function oxidases (MFO), glutathione-S-transferase (GST), acethylcholinesterase (AChE), and insensitive acethylcholinesterase (iAChE) were assayed in microplates. Three replicates were performed for each enzyme and 60 males and 60 females were analyzed in each population. The New Orleans (NO) susceptible strain of Ae. aegypti was used as a susceptible reference and the threshold criteria for each enzyme were the highest NO absorbance values. In none of the 6 tests were absorbance values correlated in males and females. alpha esterases were elevated in Benito Juarez, Cozumel females and in Lazaro Cardenas males and females. beta esterases were elevated in Benito Juarez, Cozumel females and in Cozumel and Lazaro Cardenas males. Elevated esterases suggest potential insecticide-resistance mechanisms against organophosphate, carbamate, and some pyrethroid insecticides. Slightly elevated levels of MFOs appeared in Lazaro Cardenas females and in Cozumel, Isla Mujeres, and Solidaridad males. Mechanisms involving iAChE or GST were not apparent.

    Full Text Available Este trabajo examina la dinámica territorial del turismo en la isla de Cozumel, al término del siglo XX. En la primera parte, se exponen los rasgos básicos de la economía del turismo en México para, en seguida, describir los elementos fundamentales de la geografía insular de Cozumel. En una segunda sección, se analizan los principales vínculos regionales de la isla que fueron determinados a partir del origen de los turistas y de los nexos comerciales entre Cozumel y otros territorios, la importancia de éstos debe ser considerada en un contexto de ausencia casi total de actividad agrícola e industrial local. En el futuro inmediato, esta isla mexicana incrementará los ya fuertes lazos con el exterior, en razón de la cantidad de personas y productos que llegan de fuera del país; esto será particularmente cierto en vista de un relativo declinar de Cancún como destino preferencial del turismo internacional en la península de Yucatán.

    Full Text Available El turismo es un importante sector estratégico para el crecimiento económico de Quintana Roo, ya que el 75% de su población está involucrada directa o indirectamente con la actividad. Asimismo, en Cozumel, la vida económica se desarrolla alrededor del turismo de cruceros y buceo por la calidad de sus recursos naturales submarinos. Sin embargo, la dependencia económica hacia un sector de la economía, provoca alteraciones en la estructura socioeconómica de las localidades, al verse afectadas por alguna contingencia de tipo ambiental o sanitaria; ejemplo de ello es el brote del virus de la influenza AH1N1 que afectó sensiblemente al sector turístico. En este sentido, el turismo y la salud son dos conceptos estrechamente relacionados, dado que ambos inciden directamente en la economía de los países y son parte de la política social (Chávez, 1994. En la zona del Caribe existe la amenaza de contraer dengue, enfermedad transmitida por el mosquito Aedes aegypti (vector; esta afección viral genera daños cuantiosos en la economía, en las actividades productivas y en el turismo (Zúñiga et al., 2009.

  13. El nacimiento de un destino turístico en el Caribe Mexicano. Cozumel, de isla abandonada a puerto de cruceros

    Directory of Open Access Journals (Sweden)

    Luis Carlos Santander

    2011-01-01

    Full Text Available Los autores de este artículo ofrecen una explicación del origen del turismo de cruceros en Cozumel a partir de la reconstrucción de la historia económica moderna de esa isla mexicana. Se necesitó más de centuria y media para que el pueblo fundado en aquella ínsula, San Miguel de Cozumel (1848, se transformara en una ciudad cosmopolita, en el destino más importante de turismo de cruceros en el país. Cozumel comenzó como una anodina propiedad nacional, casi abandonada. Sus colonos del siglo XIX vieron pasar de lado el progreso, o mejor dicho de largo, porque los buques mercantes y de pasajeros nunca se detuvieron en la isla, a menos que los obligara un huracán, una avería mecánica o la necesidad de agua dulce. Durante la época virreinal y hasta inicios del siglo XX Cozumel sólo interesaba a la cartografía marítima, sus 45 kilómetros de extensión fueron una buena referencia para las embarcaciones que transitaban por esa ruta del mar Caribe. Pero esa misma condición la convirtió en un exitoso puerto de cruceros.

    2004-01-01

    Full Text Available This paper seeks to evaluate the current situation of the traditional and ecological brick kilns in Juarez. The evaluation is addressed in both the environmental and socio-economic context. The brick production belongs to the informal economic sector without any regulatory scheme and without taxation. Its very low technology has serious impacts on the binational environment of the Paso del Norte region, through the highly polluted emissions to the atmosphere. However, the social and economic context of people working in this industry does not allow important changes, thus, making difficult any initiative for the brick kilns improvements and relocation. The main information source was a very concise survey applied to whole universe of brick makers. Data survey was registered in a Geographic Information System (GIS environment allowing us the analysis of the brick kilns in a spatial context. Finally, this document presents a descriptive profile of the brick kilns production and for the brickmakers.

    It has been demonstrated that the human biomonitoring of susceptible populations is a valuable method for the identification of critical contaminants. Therefore, the purpose of this study was to assess the exposure profile for arsenic (As), lead (Pb), mercury (Hg), 1-hydroxypyrene (1-OHP), 1,1-bis(p-chlorophenyl)-2,2,2-trichloroethane (DDT), 1,1-dichloro-2,2-bis(p-chlorophenyl) ethylene (DDE), polybrominated diphenyl ethers (PBDEs), and polychlorinated biphenyls (PCBs) in children living in Ciudad Juarez, Chihuahua, Mexico (a major manufacturing center in Mexico). In 2012, we evaluated a total of 135 healthy children living in Ciudad Juarez since birth. The total PBDEs levels ranged from nondetectable (exposure levels to chemicals analyzed in the children living in the study community. Therefore, a biomonitoring program for the surveillance of the child population in Ciudad Juarez is necessary.

Se observó que la PMC del visitante que arriba vía cruceros en el destino se encuentra limitada por su renta estimada. Antes esto, es necesario que se valide si continúan con la estrategia de posicionamiento que tiene el destino, debido a que la PMC es baja y por ende la derrama económica que deja es limitada.

  2. Alchemy, Prophecy, and Politics in Eighteenth-Century Iberia: Anselmo Castelo Branco's Critique of Benito Feijoo.

    Science.gov (United States)

    Leitão, José Vieira

    2016-11-01

    The Benedictine monk Benito Jerónimo Feijoo (1676-1764) is now considered one of the major figures of the Spanish and Iberian Enlightenment. However his work, both in Spain and in Portugal, was far from being universally acclaimed. His critical approach to the subject of alchemy in his essay "Piedra Filosofal," published in the third volume of his magisterial Teatro Crítico Universal (1726-1739), sparked an unexpected response from the Portuguese alchemist Anselmo Castelo Branco, who sought to refute Feijoo's claims in his own work, the Ennoea. This paper presents an outline of this exchange and its position within Iberian Enlightenment circles. It further argues that Castelo Branco's defence of alchemy was informed by his political and prophetic views, in particular his adherence to the Portuguese messianic doctrine of Sebastianism.

    Directory of Open Access Journals (Sweden)

    María Isabel Rovira Martínez de Contrasta

    2014-10-01

    Full Text Available Amidst the great turmoil, appalling conditions and ineffable hardships of impoverished nineteenth-century Spain, the realist writer Benito Pérez Galdós brilliantly weaves a tale of humanity and friendship in Misericordia, a story about the compassion, unfaltering loyalty and devotion of the main character, Benina, towards her neighbors. The plot revolves strategically around the lowest and most economically deprived social group, the beggars, thus separating Galdós's Misericordia from the work of his contemporaries. In this fictional work, the lower class is given great social visibility via Benina, who constitutes the embodiment of all the values, ideology and principles the writer seeks to praise and emphasize in the story.

Initially, I analyze these two concepts, showing how and from which I set criteria. Then, based on the correspondence sent to Juarez Távora (from his personnel file, seeking to understand how the supporters of the 1930s movement – from North, but not only – helped to build Juarez as a leading figure and all the “heroism” around it, I try to catch up how his leadership was being established in the new political context, paying attention to its multiple meanings and multiple borders.

  8. From the black Atlantic to the bleak Pacific: Re-reading “Benito Cereno”

    Science.gov (United States)

    Ganser, Alexandra

    2018-01-01

    ABSTRACT Herman Melville’s novella “Benito Cereno” (1855/56) is one of the best-studied texts both within Melville’s oeuvre and nineteenth-century American literature in general. In recent decades, its puzzling structure and fragmented narrative perspective as well as its symbolism and themes have been subject to critical scrutiny mostly in the context of inquiries into the text’s racial politics regarding the institution of slavery. More specifically, the canonical tale about a slave uprising on the ship San Dominick, its detection by a Massachusetts-born captain and its consequences, has been discussed in the context of Paul Gilroy’s black Atlantic paradigm. Few readings of the tale consider the significance of the Pacific setting of a story grounded in the transatlantic slave trade but happening far away from the center of American slavery. Taking a fresh look at Melville’s tale, this essay focuses on its translation of (black) Atlantic subject matters and epistemologies onto the Pacific. Not only do I read the tale as both an Atlantic and a Pacific text, demonstrating that the institution of slavery and its specters know no geographical borders in Melville’s imagination; I also argue that piracy is an important trope in this context. Anticipating the shift of piracy cases and slavery to the Pacific towards the end of the nineteenth century, it both recalls a black Atlantic and predicts a bleak Pacific of violent imperial scenarios that would come to characterize US–Pacific relations.

    Mendez-Carrillo, Ericka Cecilia

    Economic growth and appliance saturation are increasing electricity consumption in Mexico. Annual frequency data from 1990 to 2012 are utilized to develop an error correction framework that sheds light on short- and long-run electricity consumption behavior in Ciudad Juarez, a large Mexican metropolitan economy at the border with the United States. The results for this study reveal that electricity is an inelastic normal good in this market. Moreover, natural gas is found to be a weak complement to electricity. With regards to the customer base in this urban economy, population, employment, and income exercise positive and statistically significant impacts on the demand for electricity hook-ups.

The Observatory, created in 2008, is a joint effort of the Juarez Municipal Government, Autonomous University of Ciudad Juarez (Universidad Autónoma de Ciudad Juárez), and the Pan American Health Organization. The Observatory's main objective is to propose strategies and public policy recommendations to prevent and control violence and injuries in the Juarez Municipality. Most key federal, state, and local agencies have joined this independent autonomous citizen-based initiative, feed the databases, and benefit from the information produced by a multisectoral, multidisciplinary approach. The Observatory contributes far more than the technical data provided and its facilitating functions. The clear results obtained in such a short time-as seen in the preliminary results of the case study on road injuries from January 2009 to July 2011-demonstrate the appropriateness of this course of action and should stimulate the creation of new observatories whenever and wherever needed. Lessons learned, as discussed here, can open the way to new endeavors, and current challenges show how much work remains to be done.

    Full Text Available En 1957, Elena Garro escribió la obra teatral Benito Fernández, texto en el que hace una revisión crítica a la historia nacional, el poder, la simulación y la búsqueda de la identidad personal en medio de la sociedad creada a partir de la posrevolución mexicana. La obra de la escritora es un contradiscurso a la oficialidad, a la mitificación de los hechos y héroes nacionales; lo que le interesa es resaltar el carácter racista y clasista de una nueva sociedad de dirigentes políticos en busca del bienestar personal y de grupo por encima del bien colectivo, para ello, opta porque en su obra los personajes se preocupen por comprar una cabeza, es decir, una ideología que les haga saber que existen. In 1957, Elena Garro wrote the play Benito Fernández, a text in which she critically reviews Mexico's national history, issues of power, simulation and the quest for personal identity in the midst of a society emerged in the after effects of the Mexican Revolution. This work is a counter-discourse to Mexico's official narrative and the idealization of facts and national heroes. She is interested in the racist and classist aspects of the new dominating society, which is interested in their own personal welfare over those of the collective. To do so, she makes her characters concerned about buying a head, that is, an ideology to fundament their own existence.

    This report summarizes a number of research efforts completed over the past 20 years in the El Paso del Norte region to characterize pollution sources and air quality trends. The El Paso del Norte region encompasses the cities of El Paso, Texas and Ciudad Juarez, Chihuahua and is representative of many US-Mexico border communities that are facing important air quality issues as population growth and industrialization of Mexican border communities continue. Special attention is given to a group of studies carried out under special US Congressional funding and administered by the US Environmental Protection Agency. Many of these studies were fielded within the last several years to develop a better understanding of air pollution sources and trends in this typical border community. Summary findings from a wide range of studies dealing with such issues as the temporal and spatial distribution of pollutants and pollution potential from both stationary and mobile sources in both cities are presented. Particular emphasis is given to a recent study in El Paso-Ciudad Juarez that focussed on winter season PM{sub 10} pollution in El Paso-Ciudad Juarez. Preliminary estimates from this short-term study reveal that biomass combustion products and crustal material are significant components of winter season PM{sub 10} in this international border community.

    Medullary breast cancer is a rare type, considered of good prognosis. To know the epidemiological and clinical characteristics of the population attended in the Hospital Juarez de Mexico, to know if they are alike to described worldwide and if the treatments proposed internationally are applicable for this hospitable center. We performed a retrospective analysis. Reviewing the records with histopathologic diagnosis of medullary breast cancer from February 1993 to February 2011. Finding 41 patients in the oncology unit of the institution. We report an incidence of 3.04%, originating in 11 Mexican States, with a low to middle socioeconomic level in 39.02%. The average age at the time of diagnosis was 50 years. No family history was reported but some patients had medical history for type 2 diabetes, hypertension and previous breast cancer. 63.41% were menopausal. The average clinical size of the tumor was 58 mm. The 63% of the cases were located in the left breast. The 53.1% were clinical stages I and II, 46.3% were clinical stages III and in 9.6% of the cases primary tumor could not be assessed. Only 47% of the patients had positive axillary lynph nodes at diagnosis. The inmunohistochemestry was only reported in 14 of the 41 patients, according to the molecular classification of breast cancer: 8 were triple negative, 2 luminal A, 1 luminal B and 3 Her2neu. The Mexican population presents epidemiological and clinical characteristics similar to those patients described in other studies worldwide.

    Full Text Available This research was focused on analyzing the results of the first National Assessment of Academic Achievement for Scholar Centers (ENLACE; acronym in Spanish applied during the year 2006 in the Municipality of Juarez (State of Chihuahua, Mexico. In order to conduct the spatial analysis a geographical information system (GIS was used to make a georeferenced database were all variables were connected to a point representing a school. Results of the examinations expressed as deficient, elemental, good en excellent were spatially distributed over the urban area of Ciudad Juárez. Apparently there is a high spatial correlation between ENLACE’s results with the socioeconomic level of people. In this way results going from good to excellent were spatially located over the sectors more developed of the city. Poor results going from Insufficient to Elemental were spatially located at places with higher deficits of infrastructure and low socioeconomic levels.

    Patrick Gun Cuninghame

    2007-05-01

    Full Text Available This paper’s point of departure is that the local and global configurations of identity in Ciudad Juarez, Chihuahua, and in El Paso, Texas, are determined by the processes of economic globalisation, whose main manifestation is or has been until recently the maquiladora assembly plant. Hitherto, studies on border identities have emphasized more socio-cultural processes and have not analysed economic processes sufficiently as decisive in the construction of identities. The paper’s objective is to identify the salient characteristics of the identities of maquiladora workers and ex-workers on both sides of the border and to ascertain if transnational identities are emerging because of the impacts of globalisation, and what impacts these imply for cultural and social policy in “Paso del Norte”.

    Background Agua celeste, or “heavenly water,” is the street name for a sky-blue colored solvent reportedly inhaled or ingested to produce an intoxicating effect. Study aims were to (1) describe prevalence of Agua Celestse (AC) use, and (2) identify correlates of lifetime and recent use of AC use among female sex workers who also inject drugs (FSW-IDUs) in northern Mexico. Methods Between 2008 and 2010, baseline data from FSW-IDUs ≥ 18 years old living in Tijuana or Ciudad Juarez participating in a longitudinal behavioral intervention were analyzed using logistic regression. Results Among 623 FSW-IDUs (307 from Tijuana and 316 from Ciudad Juarez (CJ)), 166 (26%) reported ever using AC, all of whom lived in CJ. Among the CJ sample, lifetime prevalence of AC use was 53%, median age of first use was 16 years (IQR: 14–23), and 10% reported it as their first abused substance. Ever using AC was independently associated with ever being physically abused and younger age, and was marginally associated with initiating injection drug use and regular sex work at age eighteen or younger. Among those ever using AC, 70/166 (42.2%) reported using it within the last 6 months, which was independently associated with using drugs with clients before or during sex, being on the street more than 8 hours per day, and younger age. Discussion We observed considerable geographic variation in the use of AC in northern Mexico. Future studies exploring factors influencing use, its precise formulation(s), and its potential health effects are needed to guide prevention and treatment. PMID:21441001

    The Oaxaca Fault represents Tertiary extensional reactivation of the Juarez shear zone constituting the boundary-suture between the Oaxaca and Juarez terranes (southern Mexico). South of Oaxaca City, the fault trace disappears and there are not clear evidences for its southward continuation at depth. The crust in southern México has been studied through seismic refraction, and seismological and magnetotelluric (MT) studies. The refraction studies did not image the Oaxaca Fault. However, previous regional MT studies suggest that the Oaxaca-Juarez terrane boundary lies to the east of the Zaachila and Mitla sub-basins, which implies sinistral displacement along the Donaji Fault. Campos-Enriquez et al. (2009) established the shallow structure of the Oaxaca-Juarez terrane boundary based in detailed gravity and magnetic studies. This study enabled: 1) to establish the shallow structure of the composite depression comprising three N-S sub-basins: the northern Etla and southern Zaachila sub-basins separated by the Atzompa sub-basin. According to the Oaxaca-Juarez terrane boundary is displaced sinistrally ca. 20 km along the E-W Donají Fault, which defines the northern boundary of the Zaachila sub-basin. At the same time,, the Oaxaca Fault may either continue unbroken southwards along the western margin of a horst in the Zaachila sub-basin or be offset along with the terrane boundary. This model implies that originally the suture was continuous south of the Donaji Fault. A constraint for the accreation of the Oaxaca and Juarez terranes. Thirty MT soundings were done in the area of the Central Valleys, Oaxaca City (southern Mexico). In particular we wanted to image the possible southward continuation of the Oaxaca Fault. 22 Mt sounding are located along two NE-SW profiles to the northern and to the south of the City of Oaxaca. To the north of Oaxaca City, the electrical resistivity distribution obtained show a clear discontinuity across the superficial trace of the Oaxaca

    This study evaluated the impact of air pollution on a group of children in Ciudad Juarez, Mexico where a large urban population of children live in poor conditions. In particular, the study examined the associations between ozone ambient levels and respiratory-related emergency visits to hospitals by children. The impact of PM10 on respiratory health was also examined. Upper respiratory infections and asthma were found to be associated with ozone ambient levels for all age groups. In children aged 5 or less, ozone exposure was related to lower respiratory infections as well. Ambient air pollutants were not related to respiratory deaths in the population of children involved in this study, but data suggests that that PM10 ambient levels might increase the risk of respiratory mortality in infants less than one year old. An increase in respiratory mortality was noted among infants from the lowest socio-economic status (SES) group. This report emphasizes the need for implementing cost effective interventions to control existing air pollution problems and to prevent the situation from worsening. 22 refs., 27 tabs., 5 figs

    In this work a technical and economical analysis of the installation of a reverse osmosis desalting plant connected to a power station that uses the combined cycle technology under a co-generation scheme is presented: production of electricity and water. The operation program of the desalting power station will be determined by the demand of energy of the combined cycle power station; the proposal is that the desalting plant operates in the hours of low load of the power station and shuts down at the peak hours of electrical energy demand. So that this study is representative, the demand curves of electric energy of the units of combined cycle of Central President Juarez Rosarito of the Comision Federal de Electricidad (CFE) have been taken and updated the data of the reverse osmosis desalting plants that are available at the moment in the market. As basis of the study the level costs will be determined so much as the electrical energy generated by the power station of combined cycle, operating inside and outside of a co-generation scheme and the costs made level for the water produced by the reverse osmosis plant under two assumptions: the first one is buying the electrical energy from CFE and the second one considering that the CFE is the owner of the desalting plant and therefore the cost of electrical energy to desalting the plant is zero. This work shows the economic impacts on the costs of the generation of electrical energy and on those of the desalted water in a co-generation scheme. The results shown in this study can be considered for the future planning in the construction of desalting plants to supply of water in the Northwestern zones of the country where serious problems of water shortage exist.

    Full Text Available O ensaio examina o caso dos feminicídios que resultaram em pelo menos 300 mulheres assassinadas durante os últimos 11 anos em Ciudad Juarez, Chihuahua, na fronteira norte do México. Em todos esses anos, as autoridades apresentaram somente uns poucos suspeitos, sem nunca conseguir convencer a opinião pública de sua culpabilidade. Impunidade e proteção dos assassinos são evidentes tanto para a opinião pública local como para os observadores internacionais. Eu sugiro que o que é escrito no corpo das mulheres brutalmente assassinadas é a assinatura de um poder local e regional que também conta com tentáculos nacionais. Esses atos de violência aparentemente irracional enunciam, para além de qualquer dúvida, o poder discricionário de seus perpetradores e o controle que eles detêm sobre pessoas e recursos de seu território, selando e reforçando com isso um pacto de fraternidade.The essay examines the case of the feminicides that rendered at least three hundred women murdered during the last twelve years in Ciudad Juárez, Chihuahua, at the Northern Mexican border. In all these years, the authorities presented only a few suspects, without ever getting to convince public opinion of their culpability. Impunity and protection for the murderers are evident to local public opinion and to international observers. I argue that what is written on the body of the brutally murdered women is the signature of a local and regional power counting also with national connections. These acts of apparently irrational violence state beyond doubt the discretionary power of their perpetrators and the control they exert over the people and resources of their territory, thus sealing and reinforcing a pact of fraternity.

    A geophysical survey of the Oaxaca Fault along the north-trending Etla and Zaachila valleys area, southern Mexico, shows a series of NNW-SSE Bouguer and magnetic anomalies with steeper gradients towards the east. The Oaxaca Fault represents Tertiary extensional reactivation of the Juarez shear zone that constitutes the boundary between the Oaxaca and Juárez terranes. Cooperative interpretation of six combined gravity and magnetic NE-SW profiles perpendicular to the valleys indicates the presence of a composite depression comprising three N-S sub-basins: the northern Etla and southern Zaachila sub-basins separated by the Atzompa sub-basin. The Etla sub-basin is bounded by the moderately E-dipping, Etla Fault and the more steeply W-dipping Oaxaca Fault, which together constitute a graben that continues southwards into the Atzompa graben. The deeper Zaachila sub-basin, south of Oaxaca city, is a wide V-shaped graben with a horst in the middle. The new geophysical data suggest that the Oaxaca-Juarez terrane boundary is displaced sinistrally ca. 20 km along the E-W Donají Fault, which defines the northern boundary of the Zaachila sub-basin. On the other hand, the Oaxaca Fault may either continue unbroken southwards along the western margin of the horst in the Zaachila sub-basin or be offset along with the terrane boundary. The sinistral movement may have taken place either during the Late Mesozoic-Early Cenozoic, Laramide Orogeny as a lateral ramp in the thrust plane or under Miocene-Pliocene, NE-SW extension. The former suggests that the Donají Fault is a transcurrent fault, whereas the latter implies that it is a transfer fault. The models imply that originally the suture was continuous south of the Donaji Fault and provide a constraint for the accretion of the Oaxaca and Juarez terranes.

    Female sex workers who inject drugs (FSW-IDUs) face elevated risk for HIV/STIs and constitute a key population for public health prevention. Through direct and indirect pathways including human rights violations, policing practices like syringe confiscation can compound FSW-IDU health risk and facilitate the spread of disease. We studied correlates of experiencing syringe confiscation among FSW-IDUs in northern Mexico, where formal policy allows for syringes to be available over the counter without a prescription, but police practices are often at odds with the law. FSW-IDUs reporting recent syringe sharing and unprotected sex with clients in Tijuana and Ciudad Juarez were administered surveys and HIV/STI testing. Logistic regression was used to identify correlates of syringe confiscation. Among 624 respondent FSW-IDUs, prevalence of syringe confiscation in the last 6 months was 48%. The following factors were positively associated with syringe confiscation: testing positive for HIV (adjusted odds ratio [aOR] = 2.54, 95% confidence interval [CI] = 1.11-5.80), reporting sexual abuse by police (aOR = 12.76, 95% CI = 6.58-24.72), engaging in groin injection (aOR = 1.84, 95% CI = 1.15-2.93), injecting in public (aOR = 1.64; 95% CI = 1.14-2.36), and obtaining syringes from pharmacies (aOR = 1.54; 95% CI = 1.06-2.23). Higher education level was negatively associated with syringe confiscation (aOR = 0.92, 95% CI = 0.87-0.98) as was frequent injection with clients within the last month (aOR = 0.64, 95% CI = 0.44-0.94). This analysis adds to the body of evidence linking unauthorized law enforcement actions targeting high-risk groups with HIV and other adverse health outcomes. Using a public health lens to conceptualize abuse as a structural risk factor, we advocate for multi-prong prevention, systematic monitoring, and evidence-based intervention response to deleterious police practices.

    Full Text Available Exploitation of the Guadalupe fur seal (GFS during the XVIII and XIX centuries almost extirpated the species. GFS were distributed from the Revillagigedo islands (Mexico to the gulf of Farallones (USA. At present, reproductive colonies are found at Guadalupe Island and San Benito Archipelago (SBA. The aim of this work was to analyze the process of re-colonization and the current status of GFS at SBA. The first births and the occupation of the west island of the SBA are also reported. Census data from 1997 to 2007 indicated an annual growth rate for the population of 21.6%. The population size, growth tendency of the colony, reproductive biology, and food preferences were also studied. A total of 2,227 GFS were counted at SBA. Three squid species (Loligo opalescens, Onychoteuthis banksii, Dosidicus gigas were found to be the main dietary components. Territoriality, activity patterns, and reproductive behavior were similar for the seals from Guadalupe Island and SBA. The mean growth rate for pups from SBA was calculated and compared to that of the pups at Guadalupe Island (SBA: 6.7 ± 1.4 kg, 68.9 ± 2.64 cm; Guadalupe Island: 5.9 ± 0.5 kg, 67.29 ± 4.3 cm. The length of food foraging trips by females was measured, suggesting that the SBA colony is probably near an important feeding area. Maternal care patterns could indicate different strategies of nursing-foraging trips between the SBA and Guadalupe Island. The population of fur seals at SBA is expected to increase as there are no limitations in terms of reproductive space or available food resources in the area.La explotación del lobo fino de Guadalupe (LFG durante los siglos XVIII y XIX casi extinguió a la especie.

    According to the special tasks of archaeologists of the German Archaeological Institute (Madrid department) geophysical investigation campaigns were realized at several sites in Andalusia during the last five years. In Munigua (Province of Seville) - a Roman municipium and centre of metal production - building structures like the city wall and production sites extra muro were investigated by means of GPR measurements. A new method permitting virtual or physical reconstructions of archaeological features in the ground is presented using the original geophysical data and avoiding the speculative aspect of previous reconstruction techniques. In addition the Roman archaeo-metallurgical remains were surveyed in order to investigate the economic base of the Roman town and its environs. Geoelectrical measurements were realized recording the complex resistivity. The extension and depth of slag heaps are estimated using 2D and 3D images of resistivity ρ and phase angle φ. The slag heaps are well-defined by IP effects from the bedrock. The results allow estimating the amount of processed metal in Munigua for the first time. The main focus of the survey in Montes de San Benito (Province of Huelva) was the investigation of the structure of a Celtiberic settlement closely connected to iron production as well. Geomagnetic mapping and GPR measurements were applied in order to detect the buried building structures and the street system. Several single buildings, the main axes and remains of furnaces were localized. A similar procedure was chosen prospecting the fortified hill of Alcorrìn (Province of Malaga), a Phoenician settlement nearby the Mediterranean coast. The both spectacular and rarely researched site is surrounded by an up to 5 m thick wall. Main goal of the two survey campaigns was the internal structure of the hill fort. Using geomagnetic mapping and GPR a second fortification system could be identified. Inside the second ring wall building structures made of mud

    Full Text Available During the last two decades of the nineteenth century, two figures of Cuban origin help to transform La estrella de Panamá, a small newspaper from the hard to reach Isthmus. José Gabriel Duque with the editorial collaboration of Domingo A. Galdós, the son of Benito Pérez Galdós’ first cousin, will include new cultural material to the paper. This article studies Benito’s presence in this newspaper starting in 1889 which begins a transatlantic dialogue with his American relative and with the readers of the paper. Several phases of this connection are discussed as well as works such as Venecia, Vergara, Los condenados and Electra. The essay concludes with 1901 when Domingo Galdós leaves the newspaper to return to Cuba after the war of independence, having fulfilled the tasks imposed on him by José Martí.Durante las últimas dos décadas del siglo diecinueve, dos figuras procedentes de Cuba transforman La estrella de Panamá, un pequeño periódico del lejano Istmo.

    The inoperative New Idria mercury mine in San Benito Co., CA, is a potential point source of Hg to the Central Valley of California. To determine the phases and the potential bioavailability of Hg present in stream bed deposits downstream of the mine, sequential chemical extractions (SCEs) targeting Hg-bearing phases and synchrotron-based spectroscopic and imaging techniques were used on sediment samples taken from the acid mine drainage (AMD) system, Hg sorbed in the laboratory to ferrihydrite (synthetic 2-line and natural), and Hg associated with diatom-rich samples. In all field samples examined, both the wet and dry seasons, removal of > 97% of the Hg required 1M KOH or harsher chemical treatments. X-ray absorption spectroscopy (XAS) showed that HgS was the dominant inorganic Hg phase present, with no detectable Hg associated with the ferrihydrite. Uptake and subsequent SCE analysis of Hg to both synthetic and natural ferrihydrite showed that 1M MgCl2 removed ≥ 90% of the total Hg, suggesting that Hg does not sorb strongly to ferrihydrite. This finding is surprising, because in most settings ferrihydrite is considered to be a strong adsorbent of heavy metals. Due to the lack of Hg sorption to ferrihydrite in field samples, another pool for the non-HgS/HgSe fraction in sediments is needed. SEM analysis of the downstream samples showed that regardless of pH, freshwater diatoms were present. To determine if diatoms were the sink for dissolved Hg in this system, SCE analysis on commercially available and diatom-rich field samples from the New Idria site and Harley Gulch (Lake County, CA) were completed. The vast majority of Hg in diatom-rich samples was removed by 1M KOH, which corresponds to the non-HgS/HgSe fraction of the New Idria field samples. Analysis for carbon and nitrogen in the diatom-rich samples showed no detectable nitrogen, indicating little to no organic material was left in the samples. We therefore infer that Hg in the diatoms is contained in

    Full Text Available In the eighth and final volume of the Antwerp Polyglot Arias Montano published a short text titled De Psalterii Anglicani Exemplari Animaduersio. In his defense of the Hebrew original of the Old Testament, Montano set out to warn the reader that some of the more esteemed manuscripts by the so-called Hebrew-haters of his time were of little value. For this purpose, Arias Montano examined a Hebrew manuscript of the Psalter considered to be of particular antiquity and significance by the powerful bishop Wilhelm D. Lindanus, and concluded that it was in fact recent and quite worthless in many aspects, thereby fiercely attacking the latter’s scholarly reputation. This attack, based in part on a false accusation, was the beginning of a scholarly controversy lasting over fifteen years. The present essay calls attention to the fact that two versions of the Animaduersio, very different from each other, can be found in surviving copies of the Polyglot Bible. In order to illuminate the circumstances that led to these versions, the author proposes a threefold goal: (1 to gather the Latin text and the Spanish translation of the two versions of the Animaduersio; (2 to examine the reasons why Arias Montano rewrote his text in the light of the private correspondence of both scholars; (3 and to propose an approximate date for each of the versions.En el octavo y último volumen de la Biblia Regia de Amberes Benito Arias Montano publicaba un breve texto titulado De Psalterii Anglicani exemplari animaduersio.

    HIV prevalence is increasing among female sex workers (FSWs) in Mexico's Northern border region, who experience multiple occupational risks. Improving vulnerable populations' education, empowerment, and access to preventive services are important components of harm reduction strategies. Given the increasing interest in adapting harm reduction principles from drug use to sex work and other public health responses to the HIV epidemic, we used a sex work harm reduction framework to guide our investigation of FSWs' HIV knowledge. From 2004-2006, FSWs aged ≥18 years in Tijuana and Ciudad Juarez participated in a behavioral intervention study and completed structured interviews. Measures included HIV knowledge assessment and factors within each domain of our theoretical framework for sex work harms: (1) socio-demographic factors that may lead to sex work, (2) sex work characteristics and behaviors that may lead to harm, and (3) mutually reinforcing harms that lead to sex work and result from it (e.g., drug abuse). Negative binomial regression identified factors independently associated with suboptimal HIV knowledge (i.e., incorrect responses during the HIV knowledge assessment). Among 924 FSWs, the median proportion of incorrect responses was nearly one third (28% incorrect). Examination of item responses revealed misconceptions regarding specific transmission and prevention mechanisms, including prevention of mother to child transmission. Suboptimal HIV knowledge was independently associated with older age, lower education, living in Tijuana (vs. Ciudad Juarez), inconsistent condom use for vaginal sex with male clients, and lacking prior HIV testing. Our application of a sex work harm reduction framework to the study of FSWs' HIV knowledge is an important first step in enhancing HIV prevention efforts in Northern Mexican border cities. Our findings imply that interventions should identify and discredit local HIV misconceptions to improve knowledge of specific HIV

    Paired indoor and outdoor concentrations of fine and coarse particulate matter (PM), PM2.5 reflectance [black carbon(BC)], and nitrogen dioxide (NO 2 ) were determined for sixteen weeks in 2008 at four elementary schools (two in high and two in low traffic density zones) in a U.S.-Mexico border community to aid a binational health effects study. Strong spatial heterogeneity was observed for all outdoor pollutant concentrations. Concentrations of all pollutants, except coarse PM, were higher in high traffic zones than in the respective low traffic zones. Black carbon and NO 2 appear to be better traffic indicators than fine PM. Indoor air pollution was found to be well associated with outdoor air pollution, although differences existed due to uncontrollable factors involving student activities and building/ventilation configurations. Results of this study indicate substantial spatial variability of pollutants in the region, suggesting that children's exposures to these pollutants vary based on the location of their school. - Highlights: → First binational investigation characterizing traffic air pollutants at four schools in El Paso, USA and Cd. Juarez, Mexico. → Paired in-outdoor sampling of PM 2.5 , PM 10-2.5 , reflectance [black carbon(BC)], and NO 2 for 16 weeks in 2008 at each school. → Two schools (one in each city) were located in high traffic density areas and the other two in areas of low traffic density. → Usage of spatially resolved environmental indictors of traffic pollutants in a range of exposure settings. → Substantial intra-urban spatial variability in pollutant concentrations observed between and within the two cities. - Spatial variability in traffic-mediated pollutant concentrations can exist at the intra-urban level and ambient monitoring sites may not accurately represent these concentration gradients.

    Diabetes Mellitus (DM) type 2 is a common pathology with multifactorial etiology, which exact genetic bases remain unknown. Some studies suggest that single nucleotides polymorphisms (SNPs) in the CAPN10 gene (Locus 2q37.3) could be associated with the development of this disease, including the insertion/deletion polymorphism SNP-19 (2R→3R). The present study determined the association between the SNP-19 and the risk of developing DM type 2 in Ciudad Juarez population. For this study 107 participants were selected: 43 diabetics type 2 (cases) and 64 non diabetics with no family history of DM type 2 in first grade (control). Anthropometric studies were realized as well as lipids, lipoproteins and serum glucose biochemical profiles. The genotypification of SNP-19 was performed using peripheral blood lymphocytes DNA, polymerase chain reactions (PCR), and electrophoretic analysis in agarose gels. Once obtained the genotypic and allelic frequencies, the Hardy-Weinberg equilibrium test (GenAlEx 6.4) was also performed. Using the X² analysis it was identified the genotypic differences between cases and control with higher frequency of the homozygous genotype 3R of SNP- 19 in the cases group (0.418) compared to control group (0.265). Also, it was observed an association between genotype 2R/3R with elevated weight, body mass index, and waist and hip circumferences, but only in the diabetic group (P=< 0.05). The findings in this study suggest that SNP-19 in CAPN10 may participate in the development of DM type 2 in the studied population. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

    Full Text Available The abundance of California sea lions (Zalophus californianus (CSLs and Guadalupe fur seals (Arctocephalus philippii townsendi (GFSs from the San Benito Archipelago (SBA was determined through nine monthly surveys in 2014-2015. Assessment of their foraging habits was examined based on the isotopic analysis of pups (maternal indicators (SIAR/SIBER-R. Environmental variability between 2014 and 2015 was also analyzed, in terms of sea surface temperature (SST and chlorophyll (Chl-a concentration. Both otariids reached their highest abundance in July of both years; however, relative to 2014, the 2015 survey showed a 59.7% decline in the total GFS abundance and a 42.9% decrease of GFS pups, while total CSL abundance decreased 52.0% and CSL pup presence decreased in 61.7%. All monthly surveys for both otariids showed a similar trend (>50% decrease in 2015. Compared to 2014, the 2015 GFSs isotopic niche was three times larger (2.0 in 2015, 0.6 in 2014 and the δ13C was significantly lower. CSLs also showed significantly lower δ13C and higher δ15N in 2015. Interannual segregation was greater for CSLs, and their pup body mass was also significantly lower during the 2015 breeding season (mean = 8.7 kg than in the same season of 2014 (mean = 9.9 kg. The decrease in δ13C for both otariids reflected a more oceanic foraging; most likely associated with the decline in primary productivity in surrounding areas to the SBA, related to a higher SST caused by the 2015 ENSO, with a subsequent increase in foraging effort. These would explain the fewer observed individuals on land, especially pups, which showed diminished body condition (CSLs. This study highlights the importance of marine mammals as sentinel species that respond dynamically to changes in environment, providing valuable information on the effect of ENSO on pinnipeds in Mexican waters.

    Texas colonias are unincorporated subdivisions characterized by inadequate water and wastewater infrastructure, inadequate drainage and road infrastructure, substandard housing, and poverty. Since 1989 the Texas Legislature has implemented policies to halt further development of colonias and to address water and wastewater infrastructure needs in existing and new colonias along the border with Mexico. Government programs and non-government and private organization projects aim to address these infrastructure needs. Texas Tech University's Water Resources Center demonstrated the use of alternative on-site wastewater treatment in the Green Valley Farms colonia, San Benito, Texas. The work in Green Valley Farms was a component of a NASA-funded project entitled Evaluation of NASA's Advanced Life Support Integrated Water Recovery System for Non-Optimal Conditions and Terrestrial Applications. Two households within the colonia are demonstration sites for constructed wetlands. A colonia resident and activist identified educational opportunities for colonia children as a primary goal for many colonia residents. Colonia parents view education as the door to opportunity and escape from poverty for their children. The educational outreach component of the project in Green Valley Farms was a Science and Space Club for middle-school age students. Involved parents, schoolteachers, and school administrators enthusiastically supported the monthly club meetings and activities. Each month, students participated in interactive learning experiences about water use and reuse in space and on earth. Activities increased knowledge and interest in water resource issues and in science and engineering fields. The Institute for the Development and Enrichment of Advanced Learners (IDEAL) at Texas Tech University provided full scholarships for five students from Green Valley Farms to attend the Shake Hands With Your Future camp at Texas Tech University in June 2003.

    de control de la contaminación atmosférica para evitar que empeore la situación actual.OBJECTIVE: To assess the impact of atmospheric pollutants on the respiratory health of children of different age groups in Juarez City, Chihuahua, Mexico. MATERIAL AND METHODS: Data on emergency room visits between 1997 and 2001 for respiratory diseases in children less than 17 years old were obtained from hospitals in the Juarez City belonging to the Mexican Social Security Institute (IMSS. Diseases were classified into three groups according to ICD 9th and 10th codes: a upper respiratory diseases, b lower respiratory diseases, and c asthma attacks. This information was stratified by age group (5 years. Daily air pollution data (ozone and PM10 and weather conditions were obtained from the Monitoring Network System in Juarez City. Statistical analysis was carried out using a Generalized Additive Model assuming a Poisson distribution. RESULTS: Ozone concentrations, but not PM10, were statistically associated with emergency room visits for respiratory diseases, mainly among children 5 years old or younger. In this group, an increase of 20 ppb 1-hr maximum for ozone was associated with an increase of 8.3% in the number of emergency room visits for upper respiratory diseases, with a 3-day exposure lag; and an increase of 12.7% in the number of emergency room visits for lower respiratory diseases when considering a 4-day exposure lag in a maximum 8-hr mobile average. The largest effect for the complete sample and for the group 6 to 16 years of age was observed for 3-day lag (5.1% for an increase of 20 ppb 1-hr maximum for ozone. For the 6 to16 year old group we did not find a significant effect. CONCLUSION: The wide range of risk is quite important and might represent a substantial cost for the health system as well as for the society. Our results emphasize the need to implement preventive and control measures for air pollution and avoid the worsening of the present situation.

    Full Text Available Since 2008, Ciudad Juarez (Chihuahua, Mexico has been undergoing a wave of violence due to a drug war, making the city a difficult environment in which to raise a family. This study uses qualitative methodology that incorporates 16 in-depth interviews with parents of children ages 0-5 years and 9 sets of photos from a subset of interviewed parents. The study explores how families' economic, social, and cultural capital has been disrupted by the violence and how it affects children's well-being. Social and economic capital declined significantly because of the violence as families experienced crime, had increased difficulty finding and maintaining employment, and decreased their interactions outside the home. Interviews also suggested that opportunities to gain cultural capital decreased because of this isolation. Understanding the detrimental effects of violence on families' capital can contribute to understanding children's well-being in violence-stricken communities.Desde el 2008, Ciudad Juárez (Chihuahua, México ha experimentado una ola de violencia debida a una guerra entre narcotraficantes, que convirtió a la ciudad en un entorno difícil para criar una familia.

Sometimes, the victims, their descendents or organizations, have claimed by the injustice done. This work tries to be a claim for the more than 300 women victims of rape and homicide, in Ciudad Juarez, Chihuahua, Mexico. More than three hundred women have disappeared over the last decade (1993-2003; many of them were later found raped, mutilated and murdered. Remembering the principlism, the emphasis is done with a postmodern reflection about bioethics, power, gender and injustice. An analysis of the violence is done like a public health problem, with a special emphasis in the sexual health and the violence against the feminine gender. A comment about the relationship between rape and homicide against women is done. Finally, a comment about a spine-chilling Mexican case, "the dead women of Juarez", is included. Analyzing epidemiological data about rape and homicide in Mexico, it is particularly important to point out that the Juarez’s cases are not "typical"; they are really different

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

  5. Aerosol characterizaton in El Paso-Juarez airshed using optical methods

    2011-12-01

    The assessment and characterization of atmospheric aerosols and their optical properties are of great significance for several applications such as air pollution studies, atmospheric visibility, remote sensing of the atmosphere, and impacts on climate change. Decades ago, the interest in atmospheric aerosols was primarily for visibility impairment problems; however, recently interest has intensified with efforts to quantify the optical properties of aerosols, especially because of the uncertainties surrounding the role of aerosols in climate change. The main objective of the optical characterization of aerosols is to understand their properties. These properties are determined by the aerosols' chemical composition, size, shape and concentration. The general purpose of this research was to contribute to a better characterization of the aerosols present in the Paso del Norte Basin. This study permits an alternative approach in the understanding of air pollution for this zone by analyzing the predominant components and their contributions to the local environment. This dissertation work had three primary objectives, in which all three are intertwined by the general purpose of the aerosol characterization in the Paso del Norte region. The first objective was to retrieve the columnar aerosol size distribution for two different cases (clean and polluted scenarios) at each season (spring, summer, fall and winter) of the year 2009. In this project, instruments placed in buildings within the University of Texas at El Paso (UTEP) as well as a monitoring site (CAMS 12) from the Texas Commission on Environmental Quality (TCEQ) provided the measurements that delimited the aerosol size distribution calculated by our model, the Environmental Physics Inverse Reconstruction (EPIRM) model. The purpose of this objective was to provide an alternate method of quantifying and size-allocating aerosols in situ, by using the optical properties of the aerosols and inversely reconstruct and retrieve the size distribution of them. This method permits the assessment of aerosols in the ambient in-situ, without physically extracting them from their current state, as the filter technique does. The second objective was an analysis and comparison of the aerosol optical thickness (AOT) data between ground-based instruments and satellite data. In this project, the groundbased instruments are the Multi Filter Rotating Shadowband Radiometers (MFRSR) installed at UTEP and the nearest sun photometer facility, a NASA's Aerosol Robotic Network (AERONET), located at White Sands, New Mexico. The satellite data is provided by the NASA's Multi-angle Imaging Spectro-radiometer (MISR) instrument located in the Terra satellite. Finally, the third objective was to estimate ground particulate matter concentration of particles no greater than 2.5 mum in diameter (PM2.5) by using the MISR's satellite data. This objective was achieved by implementing an empirical mathematical model that includes measured data. In addition, this model addressed the geographic characteristics of the region as well as several factors such as season, relative humidity (RH) and the height of the planetary boundary layer (PBL).

    To investigate the prevalence and correlates of concurrent (overlapping) sexual partnerships among female sex workers (FSWs) and their non-commercial male partners in two Mexico-US border cities. A cross-sectional survey of FSWs and their non-commercial male partners was conducted in Tijuana and Ciudad Juárez, Mexico (2010-2011). Eligible FSWs and verified non-commercial partners were aged ≥18 years; FSWs had ever used hard drugs (lifetime) and recently exchanged sex for money, drugs or other goods (past month). Participants underwent baseline questionnaires obtaining dates of sex and condom use with ≤5 other recurring partners, including FSWs' regular clients. These dates were compared with dates of sex with enrolled study partners to determine overlap (ie, 'recurring' concurrency). Bivariate probit regression identified recurring concurrency correlates. Among 428 individuals (214 couples), past-year recurring concurrency prevalence was 16% and was higher among women than their non-commercial male partners (26% vs 6%). In 10 couples (5%), both partners reported recurring concurrency. The majority of couples (64%) always had unprotected sex, and most of the individuals (70%) with recurring concurrency 'sometimes' or 'never' used condoms with their concurrent partners. Recurring concurrency was positively associated with FSWs' income, men's caballerismo (a form of traditional masculinity) and men's belief that their FSW partners had sexually transmitted infections (STIs). Recurring concurrency, representing sustained periods of overlapping partnerships in which unprotected sex was common, should be addressed by couple-based STI prevention interventions.

    2005-01-01

    Full Text Available The essay examines the case of the feminicides that rendered at least three hundred women murdered during the last twelve years in Ciudad Juárez, Chihuahua, at the Northern Mexican border. In all these years, the authorities presented only a few suspects, without ever getting to convince public opinion of their culpability. Impunity and protection for the murderers are evident to local public opinion and to international observers. I argue that what is written on the body of the brutally murdered women is the signature of a local and regional power counting also with national connections. These acts of apparently irrational violence state beyond doubt the discretionary power of their perpetrators and the control they exert over the people and resources of their territory, thus sealing and reinforcing a pact of fraternity.

    This paper presents a theoretical study of how wind power can be complemented by hydropower. A conceptual framework is provided for a hybrid power station that produces constant power output without the intermittent fluctuations inherent when using wind power. Two hypothetical facilities are considered as case studies. One of them is a hydropower plant located on the ''Presidente Benito Juarez'' dam in Jalapa del Marques, Oaxaca, Mexico. The other hypothetical facility is a wind farm located near ''La Venta's', an area in Juchitan, Oaxaca, Mexico. The wind-hydro-power system is a combined wind and hydro power plant in a region that is rich in both resources. The model shows that the hybrid plant could provide close to 20 MW of firm power to the electrical distribution system. On a techno-economic basis, we obtain the levelized production cost of the hybrid system. Taking into account two different discount rates of 7% and 10%, figures for levelized production cost are developed. (author)

    The effective operation of the steam turbines is important to the world industries, but as all machinery, it is necessary to constantly examine and give maintenance to this equipment with the purpose of producing better results. Yet, many steam turbines arrive at an operation period of 30 or 40 years, over their original design capacity. A factor like this, only augments the probabilities of future problems with the casings, such as: thermal fatigue fissures, deformation of the horizontal union and erosion problems in the low pressure housings. The deformation of the casing can affect its capacity to maintain aligned the stationary parts of the turbine, as a consequence, damages can appear in the fixed and rotary components by interference or friction. Also, the water induction can deform the casing to such a degree that, the alignment of the stationary parts is altered until it causes contact and friction between stationary and rotary parts. However, depending on the type and degree of the casing deformation, different methods of rehabilitation can be applied. The core goal is to recover the planarity of the union of the flanges, re-machining the plane of the flange of the upper and lower casing or, alternatively, to carry out a scraping by hand. [Spanish] El funcionamiento eficaz de las turbinas de vapor es importante para las industrias del mundo, pero como toda maquinaria, es necesario examinar y dar mantenimiento constantemente a este equipo con la finalidad de producir mejores resultados. Con todo, muchas turbinas de vapor llegan a un periodo de operacion de 30 o 40 anos, por encima de su capacidad de diseno original. Un factor como este, solo eleva las probabilidades de futuros problemas con las carcasas, tales como: fisuras por fatiga termica, deformacion de la union horizontal y problemas de erosion en las carcasas de baja presion. La deformacion de la carcasa puede afectar su capacidad para mantener alineadas las partes estacionarias de la turbina, como consecuencia, pueden presentarse danos en los componentes fijos y rotatorios por interferencia o rozamiento. Asimismo, la induccion de agua puede deformar la carcasa a tal grado que, la alineacion de las partes estacionarias se altera hasta provoca contacto y rozamiento entre partes estacionarias y rotatorias. Ahora bien, dependiendo del tipo y grado de la deformacion de la carcasa, se pueden aplicar diferentes metodos de rehabilitacion. Lo medular es restaurarla planicidad de la union de las bridas, remaquinando el plano de la brida de la carcasa inferior y superior o, alternativamente, llevar a cabo un escrapeado manual.

    Our objective was to evaluate the activities of some enzymes of the heme biosynthesis pathway and their relationship with the profile of urinary porphyrin excretion in individuals exposed chronically to arsenic (As) via drinking water in Region Lagunera, Mexico. We selected 17 individuals from each village studied: Benito Juarez, which has current exposure to 0.3 mg As/l; Santa Ana, where individuals have been exposed for more than 35 years to 0.4 mg As/l, but due to changes in the water supply (in 1992) exposure was reduced to its current level (0.1 mg As/l), and Nazareno, with 0.014 mg As/l. Average arsenic concentrations in urine were 2058, 398, and 88 {mu}g As/g creatinine, respectively. The more evident alterations in heme metabolism observed in the highly exposed individuals were: (1) small but significant increases in porphobilinogen deaminase (PBG-D) and uroporphyrinogen decarboxylase (URO-D) activities in peripheral blood erythrocytes; (2) increases in the urinary excretion of total porphyrins, mainly due to coproporphyrin III (COPROIII) and uroporphyrin III (UROIII); and (3) increases in the COPRO/URO and COPROIII/COPROI ratios. No significant changes were observed in uroporphyrinogen III synthetase (UROIII-S) activity. The direct relationships between enzyme activities and urinary porphyrins, suggest that the increased porphyrin excretion was related to PBG-D, whereas the increased URO-D activity would enhance coproporphyrin synthesis and excretion at the expense of uroporphyrin. None of the human studies available have reported the marked porphyric response and enzyme inhibition observed in rodents. In conclusion, chronic As exposure alters human heme metabolism; however the severity of the effects appears to depend on characteristics of exposure not yet fully characterized. (orig.)

    Full Text Available El partido de Benito Juárez, ubicado en el centro-sur de la provincia de Buenos Aires (Argentina, es ambientalmente heterogéneo y productivamente mixto, con tradición predominantemente ganadera. A fin de evaluar las tendencias en el uso de la tierra, se describió la evolución de los diferentes rubros productivos y su diversidad durante el periodo 1998-2007, sobre la base de una selección de 30 establecimientos. El pastizal natural ocupó la mayor proporción de superficie promedio en el período considerado, pero reflejó una pérdida de 23 puntos porcentuales compensada sólo parcialmente por un aumento de pasturas perennes. La suma de ambos recursos forrajeros evidenció una caída en la superficie destinada a ganadería y, al final del periodo, fue ligeramente superada por la superficie destinada a cultivos anuales. Entre éstos, la soja fue el cultivo con mayor expansión pero su participación relativa alcanzó sólo el 11,02%. Paralelamente, la diversidad productiva, estimada mediante una adaptación del índice de diversidad de Shannon, aumentó 30,84%. Aunque es evidente el avance de cultivos anuales en desmedro de pastizales naturales, el reemplazo parcial de estos últimos por pasturas perennes y el aumento en la diversidad productiva limitan los riesgos ambientales potenciales, puestos de manifiesto en otras regiones del país.Benito Juarez county, in the central-south Buenos Aires province (Argentina, is environmentally and productively heterogeneous, with predominance of cattle farming. In order to evaluate the tendencies in land use, the evolution of different productive items and their diversity throughout the period 1998- 2007 were described on the basis of 30 farms selected. The grasslands occupied the greater proportion of the area throughout the period studied, but they reflected a loss of 23 percentage points which was only partially compensated by an increase of perennial pastures.

    Full Text Available Las encefalitis son procesos inflamatorios de diverso origen, entre las cuales se incluyen las autoinmunes. La identificación de anticuerpos contra el receptor N-metil-D-aspartato permitió la caracterización clínico-inmunológica de una entidad susceptible a tratamiento inmunomodulador. Descripta originalmente en mujeres jóvenes, asociada a teratoma de ovario, es hoy una entidad reconocida en niños aun en ausencia de tumores detectables. El objetivo del trabajo, realizado a través de la revisión de historias clínicas, fue describir las características clínicas, evolutivas y los hallazgos en estudios complementarios de once niños con diagnóstico confirmado de esta entidad a través de la identificación de los anticuerpos específicos. Todos debutaron con síntomas psiquiátricos, en nueve de ellos asociando a convulsiones, y dos a movimientos extrapiramidales. En su evolución, todos presentaron compromiso del lenguaje, nueve, síntomas autonómicos graves, en uno con hipoventilación y requerimientos de ARM. La RM de cerebro fue anormal en tres. Ocho tuvieron EEG con asimetría del voltaje y/o amplitud, tres de ellos presentaron espigas. En el LCR seis tuvieron pleocitosis y tres de siete bandas oligoclonales positivas. Cinco, serologías IgM para micoplasma. El aumento de CPK en coincidencia con antipsicóticos ocurrió en cinco. Con el tratamiento inmunomodulador, cinco tuvieron recuperación total, tres, alteraciones conductuales/cognitivas y uno déficits severo. Un paciente resolvió su cuadro clínico sin tratamiento. En ninguno se detectó tumor asociado. Concluimos que frente a un niño con encefalopatía aguda y clínica compatible con esta entidad, una vez descartada causa infecciosa, se debe comenzar tratamiento inmunomodulador precozmente, evitar la utilización de fármacos antipsicóticos y realizar la búsqueda de posibles tumores ocultos.

The key to the investigation of "Call of Juarez" appears to be the analysis of the intertextual references and the remediation of the Western convention. In order to explain the popularity of Western themed games, the author argues that the reasons responsible for th...

    Female sex workers (FSWs) aged ≥18 years without known HIV infection living in Tijuana and Ciudad Juarez who had recent unprotected sex with clients underwent interviews and testing for Chlamydia and gonorrhea using nucleic acid amplification. Correlates of each infection were identified with logistic regression. Among 798 FSWs, prevalence of Chlamydia and gonorrhea was 13.0% and 6.4%. Factors independently associated with Chlamydia were being younger, working in Tijuana versus Ciudad Juarez, and recent methamphetamine injection. Factors independently associated with gonorrhea were working in Tijuana versus Ciudad Juarez, using illegal drugs before or during sex, and having a recent male partner who injects drugs. Chlamydia and gonorrhea infection were more closely associated with FSWs’ drug use behaviors and that of their sexual partners than with sexual behaviors. Prevention should focus on subgroups of FSWs and their partners who use methamphetamine and who inject drugs. PMID:20852194

    Surveillance for evidence of West Nile virus (WNV) infection in taxonomically diverse vertebrates was conducted in the Yucatan Peninsula of Mexico in 2003 and 2004. Sera from 144 horses on Cozumel Island, Quintana Roo State, 415 vertebrates (257 birds, 52 mammals, and 106 reptiles) belonging to 61 species from the Merida Zoo, Yucatan State, and 7 farmed crocodiles in Ciudad del Carmen, Campeche State were assayed for antibodies to flaviviruses. Ninety (62%) horses on Cozumel Island had epitope-blocking enzyme-linked immunosorbent assay (ELISA) antibodies to flaviviruses, of which 75 (52%) were seropositive for WNV by plaque reduction neutralization test (PRNT). Blocking ELISA antibodies to flaviviruses also were detected in 13 (3%) animals in the Merida Zoo, including 7 birds and 2 mammals (a jaguar and coyote) seropositive for WNV by PRNT. Six (86%) crocodiles in Campeche State had PRNT-confirmed WNV infections. All animals were healthy at the time of serum collections and none had a history of WNV-like illness.

    Background We evaluated brief combination interventions to simultaneously reduce sexual and injection risks among female sex workers who inject drugs (FSW-IDUs) in Tijuana and Ciudad Juarez, Mexico during 2008–2010, when harm reduction coverage was expanding rapidly in Tijuana, but less so in Juarez. Methods FSW-IDUs ≥18 years reporting sharing injection equipment and unprotected sex with clients within the last month participated in a randomized factorial trial comparing four brief, single-session conditions combining either an interactive or didactic version of a sexual risk intervention to promote safer sex in the context of drug use, and an injection risk intervention to reduce sharing of needles/injection paraphernalia. Women underwent quarterly interviews and testing for HIV, syphilis, gonorrhea, Chlamydia and Trichomonas, blinding interviewers and assessors to assignment. Poisson regression with robust variance estimation and repeated measures ordinal logistic regression examined effects on combined HIV/STI incidence and receptive needle sharing frequency. Findings Of 584 initially HIV-negative FSW-IDUs, retention was ≥90%. After 12 months, HIV/STI incidence decreased >50% in the interactive vs. didactic sex intervention (Tijuana:AdjRR:0.38,95% CI:0.16–0.89; Juarez: AdjRR:0.44,95% CI:0.19–0.99). In Juarez, women receiving interactive vs. didactic injection risk interventions decreased receptive needle-sharing by 85% vs. 71%, respectively (p = 0.04); in Tijuana, receptive needle sharing declined by 95%, but was similar in active versus didactic groups. Tijuana women reported significant increases in access to syringes and condoms, but Juarez women did not. Interpretation After 12 months in both cities, the interactive sexual risk intervention significantly reduced HIV/STI incidence. Expanding free access to sterile syringes coupled with brief, didactic education on safer injection was necessary and sufficient for achieving robust, sustained

    Full Text Available The government constituted the Federal Board of Material Improvements in order to manage and control the economic resources and the construction of public works at México’s borders and ports. The general purpose of this research was to analyze how this agency was established and operated in Ciudad Juarez, in the context of the centralization/federalization of the country’s water resources, from 1931 to 1936, and, to this end, the historical archives were reviewed. One of the study’s limitations was the lack of background information about the management of the water resources in this town. Its contribution broadens the scarce existing knowledge about the boards’ functioning at the borders. Among the findings made, it can be mentioned that in the municipality of Juarez the loss of autonomy concerning water management was accompanied by a material and economic dispossession, in which several government institutions and agencies participated.

    The 1996 Paso del Norte (PdN) ozone study was conducted to improve current understanding of the significant meteorological and air quality processes that lead to high concentrations of ozone in El Paso, Texas (USA) and Ciudad Juarez, Chihuahua (Mexico). Two-hour canister samples were collected five times daily at 05.00-07.00 h, 07.00-09.00 h, 09.00-11.00 h, 11.00-13.00 h, and 15.00-17.00 h MST during intensive study periods at one urban and one rural site on each side of the border. An automated gas chromatograph was operated at one site in central El Paso. Source profiles (the fractional chemical composition of emissions) from motor vehicles, gasoline, liquefied petroleum gas, and commercial natural gas were combined with source profiles from other studies for input to the Chemical Mass Balance (CMB) receptor model to apportion the measured non-methane hydrocarbons (NMHC) to sources. On-road vehicle emissions accounted for one-half to two-thirds of the NMHC in Ciudad Juarez and El Paso with the highest contributions occurring during the morning and afternoon commute periods. Emissions from diesel exhaust contributed approximately 2-3% of NMHC in Ciudad Juarez and less than 2% in El Paso. The average sum of liquid gasoline and gasoline vapor increased during the day in Ciudad Juarez from 2% at 06.00 h to approximately 12% at 16.00 h. Diurnal and day-of-the-week patterns in the liquid gasoline contributions are essentially identical to the corresponding patterns for motor vehicle exhaust, which suggest that a large fraction of the liquid gasoline contribution may be associated with tailpipe emissions rather than evaporative emissions from motor vehicles or industrial sources. Including the sum of the two sources put the upper limit for tailpipe contributions at 60-70% of NMHC.

    Full Text Available El Killer, de Josué Montijo narra los asesinatos en serie de Juan Benito Aybar, un ciudadano “común” que súbitamente comienza a liquidar a los drogadictos de San Juan de Puerto Rico. Pero lejos de ofrecer una visión unilateral del asesino que permita descifrarlo como un psicópata tradicional, la novela entrega un conjunto de versiones contradictorias que imposibilitan cualquier intento de clasificación. En el proceso, lo siniestro irrumpe en la novela pues el lector descubre que el asesino es el último defensor del “orden convencional” en una sociedad en franca descomposición. El Killer by Josué Montijo describes the serial murders of Juan Benito Aybar, a “common” citizen who suddenly starts killing the drug addicts of San Juan. But far beyond of offering a unilateral vision of the assassin as the prototype of the “traditional psychopath”, the novel offers a set of contradictory versions making imposible any attempt of classification. In the process a sinister turn out for justice emerge as the assassin becomes a sort of defender of the “right order”.

    2013-03-01

    Full Text Available En esta monografía Guyon estudia ampliamente la Regla de San Benito, fundada por su homónimo, considerado como uno de los "Padres de Europa". Sus reglas, influidas en gran medida por el Derecho Romano, alcanzaron gran predicamento sobre todo a partir del siglo VI. Los dos pilares básicos que conformaban la Regla benedictina eran el oficio divino, de una parte, y la lección divina o el trabajo, de otra. San Benito obligaba a dedicar entre cuatro y ocho horas diarias al oficio divino y siete horas para dormir; y las restantes horas a trabajar, a estudiar o a la lectura religiosa. En caso de incumplimiento de las normas se establecían sanciones, que tenían su fundamento en el Derecho privado romano. Asimismo, diferenciaba entre la culpa y el dolo. Además, la Regla se basaba en los principios de la caridad y el acogimiento, si bien limitaba al máximo la permanencia de extranjeros dentro de la comunidad, para evitar que surgieran conflictos internos. La figura del abad en los monasterios adquiría un papel relevante en la medida en que presentaba como un auténtico Padre, pero como un Padre que juzgaba.

    2014-06-01

    Full Text Available El presente artículo pretende indagar en aspectos estructurales y temáticos de la novela La fragata de las máscaras (1996 del narrador uruguayo Tomás de Mattos. Tomando como punto de partida el Benito Cereno de Herman Melville, De Mattos construye un texto denso y laberíntico que no desmerece la prosa del escritor norteamericano. Aprovechando los cabos sueltos dejados por Melville en Benito Cereno, el uruguayo osa reescribir el episodio del motín acaecido pero invirtiendo las voces y dando protagonismo a los esclavos. Erige así una novela sugestiva en su planteamiento y compleja en su estructura, con un auténtico homenaje a la noción de transtextualidad en sentido lato, acuñada por Gérard Genette; intertextos, paratextos e hipertextos y continuas puestas en abismo se entrecruzan para conformar una novela polifónica pero no por ello estrictamente posmoderna, si nos atenemos al pensamiento del autor, muy distante del descreimiento que gobierna otros textos de la nueva novela histórica uruguaya coetáneos al que aquí analizamos.

Affections, prestige and honor all circulate as women care for themselves, as material, symbolic, emotional and corporal exchanges take place, thus initiating specific forms of sociality and new relationships. Gifts, as a system of reciprocities, generate and sustain bonds of trust; debt itself can become ambivalent, like the femininity of these women, which is questioned and reconstructed amid of oppressive contexts.

    2017-03-01

    Sentinel species such as crocodilians are used to monitor the health of ecosystems. However, few studies have documented the presence of zoonotic diseases in wild populations of these reptiles. Herein we analyzed 48 serum samples from Crocodylus acutus (n = 34) and C. moreletii (n = 14) from different sites in the state of Quintana Roo (Mexico) to detect antibodies to Leptospira interrogans by means of a microscopic agglutination test (MAT). Crocodylus acutus and C. moreletii tested positive to 11 and 9 serovars, respectively, with Grippotyphosa being the serovar with the highest prevalence in Cozumel island (100%), Banco Chinchorro Biosphere Reserve (70.6%), and Río Hondo (100%), while in Chichankanab Lake, it was Bratislava (75%). Titers ranged from 1:50 to 1:3200, and the most frequent was 1:50 in all study sites. Leptospira is present in fresh and saltwater individuals due to the resistance of the bacterium in both environments. Cases of infected people involved with crocodile handling and egg collection suggest that these reptiles could play an important role in the transmission of leptospirosis. Preventive medicine programs should consider the monitoring of reptiles, and testing the soil and water, to prevent outbreaks of leptospirosis in facilities containing crocodiles.

    2011-09-01

    The architectural complexity of ecosystems can greatly influence their capacity to support biodiversity and deliver ecosystem services. Understanding the components underlying this complexity can aid the development of effective strategies for ecosystem conservation. Caribbean coral reefs support and protect millions of livelihoods, but recent anthropogenic change is shifting communities toward reefs dominated by stress-resistant coral species, which are often less architecturally complex. With the regionwide decline in reef fish abundance, it is becoming increasingly important to understand changes in coral reef community structure and function. We quantify the influence of coral composition, diversity, and morpho-functional traits on the architectural complexity of reefs across 91 sites at Cozumel, Mexico. Although reef architectural complexity increases with coral cover and species richness, it is highest on sites that are low in taxonomic evenness and dominated by morpho-functionally important, reef-building coral genera, particularly Montastraea. Sites with similar coral community composition also tend to occur on reefs with very similar architectural complexity, suggesting that reef structure tends to be determined by the same key species across sites. Our findings provide support for prioritizing and protecting particular reef types, especially those dominated by key reef-building corals, in order to enhance reef complexity.

  20. Invasive reptiles and amphibians: global perspectives and local solutions

    2010-01-01

    In the annals of invasive species biology, higher taxa such asmammals, plants and insects have received the lion’s shareof research attention, largely because many of these invadershave demonstrated a remarkable ability to degrade ecosys-tems and cause economic harm. Interest in invasive reptilesand amphibians (collectively ‘herpetofauna’, colloquially‘herps’) has historically lagged but is now garnering in-creased scrutiny as a result of their escalating pace ofinvasion. A few herpetofaunal invaders have received con-siderable attention in scientific and popular accounts, in-cluding the brown treesnakeBoiga irregularison Guam,Burmese pythonPython molurusin Florida, Coqu´ıEleutherodactylus coquiin Hawaii and cane toadBufomarinusin Australia. However, relatively few are aware ofmany emerging and potentially injurious herpetofaunalinvaders, such as Nile monitorsVaranus niloticusin Flor-ida, common kingsnakesLampropeltis getulain the CanaryIslands, boa constrictorsBoa constrictoron Aruba andCozumel, or a variety of giant constrictor snakes in PuertoRico. For the vast majority of the most commonlyintroduced species, real or potential impacts to nativeecosystems or human economic interests are poorly under-stood and incompletely explored; major pathways of intro-duction have only recently been elucidated, and effectivemanagement interventions have been limited (Kraus, 2009).

  1. Landscape and vegetation change on the Iberian Peninsula during the Roman Epoch - A reconstruction based on Geo-Bioarchives

    Schneider, Heike

    2010-05-01

    Archaeological investigations expect that first strong landscape changes on the Iberian Peninsula based on Roman Occupation (Schattner 1998, Teichner 2007). Actual sedimentological investigations in flood plains, lagoons and estuaries do not reflect this development. They often show a decrease in sedimentation during this period (Thorndycraft & Benito 2006 a/b). In contrast analyses on sediments from roman dams (Hinderer et al. 2004, Solanas 2005) document massive erosion processes. The aim of this presented project is to reconstruct the effects of the roman land use system on vegetation and landscape development. Therefore different Geo-Bioarchives on several sites of Portugal and Spain - estuaries, palaeoriver channels and roman dams - are actually investigated with a high temporal resolution using palynological and sedimentological methods. First results show, that the anthropogenic impact starts clearly before roman time with an peak in human activity during Iron Age (Schneider et al. 2008). During the roman occupation phase different effects are visible. The inland areas document a massive increase in vegetation change, while the coastal areas were stronger developed before and show only slightly and very local changes in land use and vegetation.

    This study quantitatively examined the prevalence and correlates of short-term sex work cessation among female sex workers who inject drugs (FSW-IDUs) and determined whether injection drug use was independently associated with cessation. We used data from FSW-IDUs (n=467) enrolled into an intervention designed to increase condom use and decrease sharing of injection equipment but was not designed to promote sex work cessation. We applied a survival analysis that accounted for quit-re-entry patterns of sex work over 1-year stratified by city, Tijuana and Ciudad Juarez, Mexico. Overall, 55% of participants stopped sex work at least once during follow-up. Controlling for other characteristics and intervention assignment, injection drug use was inversely associated with short-term sex work cessation in both cities. In Ciudad Juarez, women receiving drug treatment during follow-up had a 2-fold increase in the hazard of stopping sex work. In both cities, income from sources other than sex work, police interactions and healthcare access were independently and significantly associated with shorter-term cessation. Short-term sex work cessation was significantly affected by injection drug use. Expanded drug treatment and counseling coupled with supportive services such as relapse prevention, job training, and provision of alternate employment opportunities may promote longer-term cessation among women motivated to leave the sex industry.

    Full Text Available This research analyzes the situation of journalism in a high risk area, Ciudad Juarez, Mexico. The analysis is based on the knowledge and analysis of the training activity, violence and corruption denounced by Juarez Journalists Association, founded and run by women journalists. A meeting with journalists of the association and in-depth interviews are the main methodological tools to understand the meaning and value of this group of juarenses journalists. In the same way this article analyzes, through a quantitative methodology, the strategy of activism and the international projection of the association through their social networks. In addition, research is completed with a content analysis about the prevalence and significance of the ‘red note’ in El Diario de Juárez, the main newspaper in this border area, which even has a delegation in the US city of El Paso. Coverage of violence in high risk areas gives a special value to journalism in newspapers like the aforementioned and corporate work of this group of juarenses journalists.

    Medical research in the Instituto Mexicano del Seguro Social has been considered one of the most important in this country for quality and quantity. Thanks to the work and leadership of Benito Coquet, who initiated the building of the National Medical Center in 1961, and the work of two pillars of research, Luis Castelazo and Bernardo Sepúlveda, the Institute successfully improved scientific research. In the years that followed, the Institute fostered the professionalization of research, the creation of research units in different areas of science, the incorporation of consolidated groups of researchers, the relationship with other institutions, the incorporation to the Sistema Nacional de Investigadores, the editing of a journal to expose outside the work done within the Institute, and the formation of a trust to raise funds for financing. Thanks to all that, institutional research strengthened in all lines, and it was placed first, at certain times, at the national level.

  14. CORRADO GINI AND THE SCIENTIFIC BASIS OF FASCIST RACISM.

    Science.gov (United States)

    Macuglia, Daniele

    2014-01-01

    It is controversial whether the development of Fascist racism was influenced by earlier Italian eugenic research. Before the First International Eugenics Congress held in London in 1912, Italian eugenics was not characterized by a clear program of scientific research. With the advent of Fascism, however, the equality "number = strength" became the foundation of its program. This idea, according to which the improvement of a nation relies on the amplitude of its population, was conceived by statistician Corrado Gini (1884-1965) already in 1912. Focusing on the problem of the degeneration of the Italian race, Gini had a tremendous influence on Benito Mussolini's (1883-1945) political campaign, and shaped Italian social sciences for almost two decades. He was also a committed racist, as documented by a series of indisputable statements from the primary literature. All these findings place Gini in a linking position among early Italian eugenics, Fascism and official state racism.

MATERIAL AND METHODS: Between 1998 and 1999, an ecologic study was conducted. Atmospheric data were obtained from the Environmental Protection Agency (EPA, from eight monitoring stations located in Ciudad Juarez, Chihuahua, and El Paso, Texas. From July 1997 to December 1998, data from emergency room visits for respiratory illness were abstracted from existing medical records of two Mexican Institute of Social Security (IMSS hospitals in Ciudad Juarez. Diagnoses were classified into two groups: a asthma, and b upper respiratory infections (URI, according to the International Classification of Diseases (ICD-9 and/or IDC-10. Statistical analysis was carried out using the Poisson regression time series method. RESULTS: During the study period, the mean 24-hour PM10 level was 34.46 µg/m³ (SD=17.99 and the mean ozone level was 51.60 ppb (SD=20.70. The model shows that an increase of 20 µg/m³ in the mean 24-hour exposure to PM10 was related to an increase of 4.97% (95% CI 0.97-9.13 in emergency visits for asthma, with a 5-day lag, as well as to an increase of 9% (95% CI 1.8-16.8 when a cumulative 5-day exposure was considered. URI increased 2.95% as a cause of emergency room visits, for each 20 µg/m³ increase in the mean 24-hour exposure to PM10. The impact of PM10 on emergency visits for asthma was greater on days with ozone ambient levels exceeded 49 ppb (median value.

La comunidad ciega en ciudad Juárez Mexico en frontera con Estados Unidos, mantiene en nuestros días una ausencia participativa en lo cotidiano, la estructura urbana de poca inclusión, los lleva crear alternativas para su movilidad. El objetivo  de este estudio es comprender y analizar cómo es la interacción social y espacial del ciego en una ciudad deshabilitada para su movilidad. Se utilizo un enfoque cualitativo que permitiese una observación cercana al grupo mediante entrevistas semi estructurada y observación participante, se escogió a un grupo de jóvenes ciegos que asisten a la Escuela para Ciegos Luis Braille. Se encontró que la ciudad  muestra un reflejo marginal que genera restricciones en su traslado, movilidad y aprendizaje espacial manteniendo una difícil autonomía.   Abstract: The community of visually impaired persons in Ciudad Juarez, Mexico, sitting astride the United States border, is practically absent from the city's day-to-day life. Providing negligible accommodations, Ciudad Juarez is not an inclusive environment and thus the visually impaired must auto-construct their own means of mobility to get out into the broader community they inhabit. The objective of this study is to analyze and understand the social and spacial interaction of the visually impaired in a northern Mexican border city entirely unequipped for them. The study focuses on a group of students at the Luis Braille School for the Blind in Ciudad Juarez, who were interviewed and observed during a prolonged period of time, and concludes that

    Full Text Available Decarbonisation in the generation of electricity is necessary to reduce fossil fuel consumption, the pollution emitted and to meet the Energy Technology Perspectives 2 ° C Scenario (2DS targets. Small islands are not exempt from this target, so this study’s emphasis is placed on a 50-50 target: to reduce the fossil fuel consumption through electricity generation from Renewable Energy Sources (RES to cover 50% of all electric demand by 2050 on small islands. Using Cozumel Island, Mexico, as a case study, this analysis will be based on three factors: economical, technical, and land-use possibilities of integrating Renewable Energy Technologies (RETs into the existing electrical grid. This analysis is made through long-term statistical models. A deterministic methodology is used to perform time-series simulations. The selection of the best system was made on the basis of a Dimensional Statistical Variable (DSV through primary and secondary category rankings. The presented methodology determines the best systems for capturing the initial capital cost and competitiveness of this new proposal compared with the current system of electricity generation on the Island, and can be applied to small islands as well. According to the results, all systems proposed are able to completely satisfy the renewable electricity needed by 2050 in all scenarios. From the 12 system proposals that were compared, two systems, System 2 and System 7, were chosen as eligible systems to be installed. The Levelized Cost of Energy (LCOE result for System 2 was 0.2518 US$/kWh and for System 7 was 0.2265 US$/kWh by 2018 in the Base Scenario. Meanwhile, the Internal Rate of Return (IRR value fluctuated from 17.2% for System 2 to 31% for System 7.

    The queen conch ( Strombus gigas) is a commercially important marine invertebrate that is widely distributed throughout the western Atlantic, from Bermuda to Brazil. Intense exploitation has resulted in a decrease in population numbers of this species, which is listed as protected from commercial exploitation under IUCN and CITES. Previous studies on population genetics have demonstrated contrasting results in terms of the population structure of S. gigas. This research analyzed the genetic connectivity of the queen conch over a wide area of the Mesoamerican Reef System to determine whether S. gigas presents one panmictic population or a more complex structure. Furthermore, we evaluated the risk of local extinction by establishing the genetic diversity of the studied populations. High resolution was obtained for the five ISSR markers used for a total of 190 individuals, from seven localities along the Mesoamerican Reef. Our results reject the panmictic structure hypothesis for the queen conch in the study area and demonstrate genetic patchiness, indicating general homogeneity among localities that present an isolation-by-distance pattern. However, some genetic temporal variation was confirmed for the Cozumel locality. Furthermore, our results reveal self-recruitment for the Alacranes Reef aggregation and suggest sufficient connectivity with localities on the Caribbean coast to maintain high genetic diversity. With regard to genetic diversity, the results demonstrate that the queen conch is not genetically threatened in the study area. This is probably due to high annual recruitment within Caribbean queen conch aggregations, and suggests that S. gigas is a highly resilient organism. We advocate that the appropriate management of S. gigas (fishing quota and/or closed season) must be followed to attain a rapid recovery of queen conch populations. This study represents a fundamental step in the understanding of the dynamic population structure of S. gigas in the

    1999-02-01

    The authors explore the gender identities among women factory workers in Ciudad Juarez, Mexico. Using data from 3 generations of women, they show that women's participation in the maquila work force is exposing them to new ideologies which challenge traditional images embodied in the marianismo ideal of Mexican womanhood. By focusing upon women's changing experiences of courtship and motherhood, the authors suggest that conventional discourses stressing parentally supervised mate selection and full-time motherhood are being challenged by alternative ones which allow young women to socialize freely with prospective mates in unsupervised contexts, and expand the meaning of responsible motherhood to encompass full-time employment. Women workers' identities are fluid processes in permanent negotiation. ¿

  11. ELECTRICITY DEMAND IN A NORTHERN MEXICO METROPOLITAN ECONOMY

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Using an error correction framework, this study analyzes the long- and short-run dynamics of electricity demand in Ciudad Juarez, a large metropolitan economy on Mexico’s northern border. Demand is decomposed into the total number of electricity accounts and electricity usage per customer, each of which is modeled separately. A two-stage least squares approach is used to estimate the per customer electricity demand equations due to the endogeneity of the average price variable. The results indicate sustained growth in population, employment, and income can be expected to exert substantial upward pressure on regional electric power demand. Furthermore, demand is found to be price-inelastic in this metropolitan area, suggesting that rate increases can help raise the revenues necessary to fund expansion of the electrical grid.

    Full Text Available By means of the analysis of the residential and professional practices of immigrant families over Ciudad Juarez, this essay tries to show that inside the well-known abstract categories such as “popular urban residents” and “female maquila labor” exists a wide range of populational profiles that is necessary to clarify. For this reason, the work hypothesis is based on a flexible correlation of the following variables: a labor situation, b migratory status, and c the real estate and labor market exact situation. It is considered that the entrance moment on the labor and real estate markets (which speaks to us of the socio-economic and political context in which a cycle of urban integration begins, as well as the migratory situation of the head of the family, both define their labor and residential itineraries at the same time.

    Da jeg i 2006 befandt mig i Mexico City fik jeg ideen til at skrive om skyggesiderne af globaliseringen - set fra Mexico. Planen var at skrive otte artikler, der spændte fra "offshore" produktionshaller til papirløse migranter, majsbønder og gadehandlere. Jeg ville kort sagt fortælle om NAFTA......'s skyggesider (North American Free Trade Agreement). Men hver gang jeg fandt en af NAFTA's skyggesider, voksede der nye skygger frem. Når samlebåndsarbejderne bliver i produktionshallerne, er det ikke fordi, der ikke er andet at gøre. Det er snarere fordi skyggesiderne af disse "andre muligheder" overskygger...... deres egen situations skyggesider.

    Intimate partner violence (IPV) has been associated with greater vulnerability to HIV infection among women. We examined prevalence and correlates of IPV among female sex workers (FSWs) in Tijuana and Ciudad Juarez, two large Mexico-U.S. border cities where HIV prevalence is rising. Participants were 300 FSWs with a current spouse or a steady partner. Participants' mean age was 33 years, and mean number of years as a sex worker was 6 years. The prevalence of IPV in the past 6 months among participants was 35%. Using multivariate logistic regression, factors independently associated with IPV included having experienced abuse as a child, a partner who had sex with someone else, and lower sexual relationship power. Our findings suggest the need for previous abuse screening and violence prevention services for FSWs in the Mexico-U.S. border region. Careful consideration of relationship dynamics such as infidelity and relationship power is warranted when assessing for IPV risk.

Linear regressions identified correlates of current depression symptoms. In the interviews, FSW-IDUs identified drug use as a method of coping with the trauma they experienced from abuse that occurred before and after age 18 and during the course of sex work. In a multivariate linear regression model, two factors—ever experiencing forced sex and forced sex in the context of sex work—were significantly associated with higher levels of depression symptoms. Our findings suggest the need for integrated mental health and drug abuse services for FSW-IDUs addressing history of trauma as well as for further research on violence revictimization in the context of sex work in Mexico.

    A gravity study was conducted across the northern Oaxaca terrane and its bounding faults: the Caltepec and Oaxaca Faults to the west and east, respectively. These faults juxtapose the Oaxaca terrane against the Mixteca and Juarez terranes, respectively. The Oaxaca Fault also forms the eastern boundary of the Cenozoic Tehuacán depression. On the west, at depth, the Tehuacán valley is limited by the normal buried Tehuacán Fault. This gravity study reveals that the Oaxaca Fault system gives rise to a series of east tilted basamental blocks (Oaxaca Complex). The tectonic depression is filled with Phanerozoic rocks and has a deeper depocenter to the west. The gravity data also indicate that on the west, the Oaxaca Complex, the Caltepec and Santa Lucia faults continue northwestwards beneath Phanerozoic rocks. A major E-W to NE-SW discontinuity is inferred to exist between profiles 1 and 2.

Its structure initiates with a general panorama of the conceptual changes in the policies on safety in a country with the particularities of Mexico, current conceptions that approached conciliation with the citizenship. This analysis highlights Ciudad Juarez and Mexico City in two interdisciplinary case studies on this problem and a brief review of the journalistic approach. The case studies illustrate that although the social approach adopted by the institutions, has been an important step in solving the problem, there is still much to achieve true integration.

    The Freight Shuttle System (FSS) is designed to provide freight transportation services between those short and intermediate distance locations (within 600 miles) that are currently handling large volumes of freight traffic. Much like trucks, the FSS's transporters are autonomous: each transporter has its own propulsion and travels independently of other transporters. Inspired by railroads, each FSS transporter has steel wheels operating on a steel running surface and can carry either a standardsize freight container or an over-the-road truck trailer. However, unlike either rail or trucks, the FSS runs on an elevated, dedicated guideway to avoid the interference of other transportation systems. The objective of this report is to examine the potential viability for an alternative transportation system for trailers and containers in a multi-national, cross-border setting. The El Paso-Ciudad Juarez region serves as the environment of this analysis.

    Full Text Available This paper seeks to analyze public participation in water management through a survey applied to the leaders of neighborhood committees in Ciudad Juarez, Chihuahua. As part of the methodology, two variables —external and internal influences— and fourteen indicators were utilized. Results show that neighborhood committees, as a public participation structure, are in crisis. The structure shows both internal and external signs of breaking up: there are no clear mechanisms of summons or participation, nor are there any adecuate mechanisms capable of articulating demands and government authority, insofar as external political agents have been allowed to participate in internal management and committee issues. For this reason, the capacity of local neighborhood committees to make decisions regarding city water management is placed in doubt.

    The enforcement of federal safety regulations on the transport of radioactive and hazardous materials contained in the Hazardous Materials Transportation Act is the responsibility of the Department of Transportation, Nuclear Regulatory Commission, and the Environmental Protection Agency. Concern over the practice of charging less than 10% of the statutory maximum penalty and a poor record of collections raises questions about the diligence of enforcement agencies. Testimony by an Illinois state trooper revealed the extent of noncompliance, using the incident of the radioactive metal from Juarez, Mexico that was used to make table pedestals for illustration, and the state's response to the problem. Fourteen other witnesses from the enforcement agencies described procedures and problems. Additional material submitted for the record follows their testimony

    To identify factors associated with time to initiation of (i) sex work prior to injecting drugs initiation; (ii) injection drug use prior to sex work initiation; and (iii) concurrent sex work and injection drug use (i.e. initiated at the same age) among female sex workers who currently inject drugs (FSW-IDU). Parametric survival analysis of baseline data for time to initiation event. Tijuana and Ciudad Juarez situated on the Mexico-US border. A total of 557 FSW-IDUs aged ≥18 years. Interview-administered surveys assessing context of sex work and injection drug use initiation. Nearly half (n = 258) initiated sex work prior to beginning to inject, a third (n = 163) initiated injection first and a quarter (n = 136) initiated both sex work and injection drug use concurrently. Low education and living in Ciudad Juarez accelerated time to sex work initiation. Being from a southern Mexican state and initiating drug use with inhalants delayed the time to first injection drug use. Having an intimate partner encourage entry into sex work and first injecting drugs to deal with depression accelerated time to initiating sex work and injection concurrently. Early physical abuse accelerated time to initiating sex work and injection, and substantially accelerated time to initiation of both behaviors concurrently. Among female sex workers who currently inject drugs in two Mexican-US border cities, nearly half appear to initiate sex work prior to beginning to inject, nearly one-third initiate injection drug use before beginning sex work and one-quarter initiate both behaviors concurrently. Predictors of these three trajectories differ, and this provides possible modifiable targets for prevention. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    Short-term evolution (for 2001, 2005 and 2015) for the shallow aquifer of Etla Valley, Oaxaca, southern Mexico, was simulated based in a 3D hydrological model elaborated from the available geological, geophysical, geochemical, and hydrologic parameters. The numerical simulations were based on Visual MODFLOW code. These simulations indicate that, if the actual extraction regime is maintained, the drawdown of the potentiometric surface will get worse to the SE of the study area (i. e. beneath Oaxaca city). The prevailing aquifer flow direction favors the ground water pollution by fertilizers and leakage from the sewage network (dumped to the Atoyac river). According to the numerical simulation, remediation of this situation is possible if the wells located in the neighborhood of Oaxaca City are relocated at the recharge zones (i. e. at the feet from Sierra de Juarez). This remediation scenario will allow a recovery of the drawdown of the potentiometric surface.

Las simulaciones numericas fueron realizadas en Visual MODFLOW.

La contaminacion por fertilizantes y por las fugas de drenaje es favorecida por la direccion de flujo imperante en el acuifero (vaciandose en el rio Atoyac). De acuerdo a las simulaciones numericas, existe una posible remediacion de este proceso, relocalizando los pozos situados en la ciudad de Oaxaca en las zonas de recarga (i. e. en las faldas de la Sierra de Juarez). Este escenario de remediacion permitiria una recuperacion en el nivel de la superficie potenciometrica.

    Purpose To examine correlates of early initiation into sex work in two Mexico–U.S. border cities. Methods Female sex workers (FSWs) ≥18 years without known HIV infection living in Tijuana and Ciudad Juarez who had recent unprotected sex with clients underwent baseline interviews. Correlates of initiation into sex work before age 18 were identified with logistic regression. Results Of 920 FSWs interviewed in Tijuana (N=474) and Ciudad Juarez (N=446), 9.8% (N=90) were early initiators (<18 years) into sex work. Median age of entry into sex work was 26 years (range: 6–58). After adjusting for age, compared to older initiators, early initiators were more likely to use inhalants (21.1% vs 9.6%, p=0.002), initiate sex work to pay for alcohol (36.7% vs 18.4%, p<.001), report abuse as a child (42.2% vs 18.7%, p<.0001), and they were less likely to be migrants (47.8% vs 62.3%, p=0.02). Factors independently associated with early initiation included inhalant use (adjOR=2.39), initiating sex work to pay for alcohol (adjOR=1.88) and history of child abuse (adjOR=2.92). Factors associated with later initiation included less education (adjOR=0.43 per 5-year increase), migration (adjOR=0.47), and initiating sex work for better pay (adjOR=0.44) or to support children (adjOR=0.03). Conclusions Different pathways for entering sex work are apparent among younger versus older females in the Mexico–U.S. border region. Among girls, interventions are needed to prevent inhalant use and child abuse and to offer coping skills; among older initiators, income-generating strategies, childcare, and services for migrants may help to delay or prevent entry into sex work.

    Urbanization is an area of growing interest in assessing the impact of human activities on water resources in arid regions. Remote sensing techniques provide an opportunity to analyze land cover change over time, and are useful in monitoring areas undergoing rapid urban growth. This case study for the water-scarce Upper Rio Grande River Basin uses a supervised classification algorithm to quantify the rate and evaluate the pattern of urban sprawl. A focus is made on the fast growing El-Paso-Juarez metropolitan area on the US-Mexico border and the City of Las Cruces in New Mexico, areas where environmental challenges and loss of agricultural and native land to urban development are major concerns. Preliminary results show that the land cover is dominantly native with some significant agriculture along the Rio Grande River valley. Urban development across the whole study area expanded from just under 3 percent in 1990, to more than 11 percent in 2015. The urban expansion is occurring mainly around the major urban areas of El Paso, Ciudad Juarez, and Las Cruces, although there is visible growth of smaller urban settlements scattered along the Rio Grande River valley during the same analysis period. The proportion of native land cover fluctuates slightly depending on how much land is under crops each analysis year, but there is a decreasing agricultural land cover trend suggesting that land from this sector is being lost to urban development. This analysis can be useful in planning to protect the environment, preparing for growth in infrastructure such as schools, increased traffic demands, and monitoring availability of resources such as groundwater as the urban population grows.

    Full Text Available A evolução da saúde pública mexicana foi gradual. Nos séculos XIX e XX desenvolveu-se paralelamente às mudanças políticas e sociais do país. Na primeira metade do século XIX o cuidado com os doentes dependia parcialmente da caridade religiosa. Depois, instituiu-se a beneficiência pública, consolidada pelo presidente Benito Juárez (1856, forma de atendimento continuada por Porfirio Díaz (1880-1910. A partir da Revolução (1910-1917 surgiu o princípio de assistência pública como obrigação do Estado para com a sociedade. Atualmente, a assistência à saúde, e a seguridade social conjugam-se em um conceito de medicina institucional que compreende a investigação, o ensino e os serviços prestados à sociedade. Este trabalho é uma análise do desenvolvimento da saúde pública mexicana nos dois últimos séculos. Faz referência às doenças e seu controle, ao aparecimento das instituições e à evolução do conceito de saúde pública na história mexicana.During the nineteenth and twentieth centuries, its growth accompanied the country’s political and social changes. In the early half of the nineteenth century, care for the sick depended in part on religious charity. So-called public beneficial care was later introduced and consolidated under president Benito Juárez (1856 and then continued under Porfirio Díaz (1880-1910. The Mexican Revolution (1910-1917 brought the notion that public-health assistance is the State’s social responsibility. Health care and social security are now both part of so-called "institutional medicine," which also encompasses research and teaching on public health. This analysis of public-health care in Mexico examines the question of diseases and their control, the emergence of institutions, and the development of the concept of public health.

  17. Phylogeographic pattern and extensive mitochondrial DNA divergence disclose a species complex within the Chagas disease vector Triatoma dimidiata.

    Full Text Available BACKGROUND: Triatoma dimidiata is among the main vectors of Chagas disease in Latin America. However, and despite important advances, there is no consensus about the taxonomic status of phenotypically divergent T. dimidiata populations, which in most recent papers are regarded as subspecies. METHODOLOGY AND FINDINGS: A total of 126 cyt b sequences (621 bp long were produced for specimens from across the species range. Forty-seven selected specimens representing the main cyt b clades observed (after a preliminary phylogenetic analysis were also sequenced for an ND4 fragment (554 bp long and concatenated with their respective cyt b sequences to produce a combined data set totalling 1175 bp/individual. Bayesian and Maximum-Likelihood phylogenetic analyses of both data sets (cyt b, and cyt b+ND4 disclosed four strongly divergent (all pairwise Kimura 2-parameter distances >0.08, monophyletic groups: Group I occurs from Southern Mexico through Central America into Colombia, with Ecuadorian specimens resembling Nicaraguan material; Group II includes samples from Western-Southwestern Mexico; Group III comprises specimens from the Yucatán peninsula; and Group IV consists of sylvatic samples from Belize. The closely-related, yet formally recognized species T. hegneri from the island of Cozumel falls within the divergence range of the T. dimidiata populations studied. CONCLUSIONS: We propose that Groups I-IV, as well as T. hegneri, should be regarded as separate species. In the Petén of Guatemala, representatives of Groups I, II, and III occur in sympatry; the absence of haplotypes with intermediate genetic distances, as shown by multimodal mismatch distribution plots, clearly indicates that reproductive barriers actively promote within-group cohesion. Some sylvatic specimens from Belize belong to a different species - likely the basal lineage of the T. dimidiata complex, originated ~8.25 Mya. The evidence presented here strongly supports the proposition

    Full Text Available El presente artículo acomete el proyecto de dejar constancia de la importancia cultural que tiene la lectura de obras literarias. Lo literario se vincula a nuestras vidas de manera indeleble y merece la pena reflexionar sobre ello. Se reivindica la figura del escritor como elemento clave del proceso creativo, y se contempla el género novelesco a manera de fuente valiosa para la interpretación de la historia. En este sentido se estima la obra de Benito Pérez Galdós, al que algunos historiadores avezados se aproximan para confeccionar o completar su visión de hechos históricos concretos o de épocas y ambientes determinados. En el caso de Galdós, apreciamos nexos entre la literatura y la historia española del siglo XIX. Algo similar —salvando las distancias— ocurre con la novela Pequeñeces (1890, del escritor Luis Coloma, que nos ofrece una visión certera del tejido aristocrático en la convulsa España del Sexenio revolucionario (1868-1874.

Se presenta un estudio más detallado de la dramaturgia de tres autores que caracterizan muy bien sendas perspectivas teatrales en la España de ese momento: José Echegaray, Benito Pérez Galdós y Joaquín Dicenta. Y, por último, se demuestra la importancia de poder digitalizar las piezas teatrales de esta época para su conocimiento y estudio.

  3. The role of eclecticism in the introduction of modern philosophy in eighteenth century New Spain

    Full Text Available The idea that there is a straightforward causal connection between the expulsion of the Jesuits and the beginning of a real Enlightenment in Iberian America–that the absence of the Jesuits from New Spain after 1767 might have allowed a stronger influence of Enlightenment ideas that they did not accept, such as liberalism–needs to be reconsidered. This article aims to show continuities between the Mexican Jesuit generation of 1750 and the generation of Mexican scholars who replaced them in the chairs of philosophy and physics, and occupied prominent positions in New Spain’s academic life after 1767. It deals especially with Juan Benito Díaz de Gamarra y Dávalos, an author who is usually associated with the Mexican Enlightenment and understood as opposed to the Jesuits, condemned for their traditionalism and medievalism. I argue that the process of introducing modern philosophy in New Spain started with the 1750’s Mexican Jesuit generation and was followed by a second generation–represented mainly by Gamarra and Alzate–after the expulsion of the Society of Jesus in 1767.

  5. The 'International' and the 'Global' as Complementary Power Strategies within Corporate Roman Catholicism

    2010-09-01

    Full Text Available The putative resurgence of religious belief and its reinvigorated socio-political importance – or at least prominence – has prompted critical reflection on religion, broadly defined, as a new force in politics. This paper examines the ‘global’ and ‘international’ role of Roman Catholicism. Roman Catholicism has manifested itself as an actor on the international stage and as a trans-national and global ‘community’. Frequently the conceptual dividing line between these is ambiguous. Vatican City and the Holy See have both been accorded international status, the former since the conclusion of the Lateran Treaty by Italy’s fascist leader, Benito Mussolini, in 1929, the latter since the mid nineteenth century following the absorption of the Papal States into the newly unified Italian Republic. The Holy See also enjoys a special status position within the United Nations system as a non-member observer state. Following revelations of clerical child abuse the Holy See was put on the defensive in several national contexts in a public controversy that resonated much more widely. This trans-nationally organised religion has mobilised both nationally and internationally to defend its institutional interests. Through an examination of empirical instances the study sidesteps the question of whether religions are ‘global’ or ‘international’ phenomena, and draws attention to the distinct power modalities operative at the level of both international politics and in transnational or global organisation.

    In this article, we report the current surgical approach to gallbladder disease at a major referral hospital in rural Guatemala. Complications in a cohort of patients undergoing open versus laparoscopic cholecystectomy were catalogued. We reviewed cholecystectomies performed by surgeons at the Hospital Nacional de San Benito in El Peten, Guatemala, after the adoption of the laparoscopic approach. Laparoscopic cholecystectomies (LCs) between 2014 and 2015 (n = 42) were reviewed and matched by 58 randomly selected open cholecystectomies (OCs) during the same period. Patient demographics were similar in the LC and OC groups. Of the 63 patients who had elective surgery, 43 (68%) underwent OC. Conversion rate, hospital length of stay, and readmission rate were 4%, 4.8 days, and 5%, respectively. Complications were similar between groups. Despite the low number of LCs, their complications were not different from that of OCs. During the study period, a large number of cholecystectomies continued to be open, even in the elective setting. Published by Elsevier Inc.

    Full Text Available OBJECTIVE: As a consequence of environmental exposure, organochlorine pesticides accumulate in lipid rich-tissues such as maternal adipose tissue and partition to maternal blood serum and umbilical blood serum. To establish their distribution in the human body, the concentration gradients of organochlorine pesticides between these compartments were determined. MATERIAL AND METHODS: Maternal adipose tissue, blood serum and umbilical blood serum samples from 64 volunteers admitted for cesarean delivery at Hospital Benito Coquet Lagunes were studied in Veracruz during 1997 and 1998. The pesticide residues were determined by gas chromatography and results obtained from different sample groups were analyzed using Pearson correlation coefficients and simple lineal regression. RESULTS: Significant results expressed on fat basis of organochlorine pesticides indicate that 1,1,1-trichloro-2,2-bis(4-chlorophenylethane (DDT levels are higher in maternal adipose tissue (4.51 mg/kg DDE and 1.27 mg/kg pp'DDT, maternal blood serum (4.45 mg/kg DDE and 0.78 mg/kg pp'DDT, and umbilical blood serum (4.70 mg/kg DDE and 0.88 mg/kg pp'DDT, due to greater affinity of DDT for lipids. CONCLUSIONS: The statistical evaluation of results and the pairing of samples analyzed indicate that absorbed organochlorine pesticides cross the placental barrier and reach a balanced state between mother and fetus.

    Full Text Available El benedictino español Benito Feijoo (1676-1764 fue uno de los intelectuales más destacados del siglo XVIII. Sus aportaciones al mundo del pensamiento y la cultura abarcan un buen número de ensayos sobre los saberes eruditos y populares de la época. En lo que se refiere al gran alcance pedagógico de Feijoo, se advierte a un tiempo en su condición de profesor universitario, en su compromiso crítico y empírico con la eliminación de errores y en su actitud crítica y empirista, que le lleva a poner en entredicho obsoletos métodos de enseñanza. La obra del benedictino, aunque es ensayística y carece de sistematización, tiene una finalidad educativa. Este artículo, tras repasar algunos datos biográficos, se centra en algunas de sus contribuciones pedagógicas más destacadas, como el cultivo del entendimiento y la defensa de las mujeres. En definitiva, Feijoo es un iniciador, un educador de gran relevancia histórica que, en el marco de su elevada misión pedagógica, logró agitar las conciencias. Por ello, su excelsa figura continúa brillando y se sigue estudiando en este siglo XXI.

    Full Text Available Summary: Physical exercise in combination with cognitive training is known to enhance synaptic plasticity, learning, and memory and lower the risk for various complex diseases including Alzheimer’s disease. Here, we show that exposure of adult male mice to an environmental enrichment paradigm leads to enhancement of synaptic plasticity and cognition also in the next generation. We show that this effect is mediated through sperm RNA and especially miRs 212/132. In conclusion, our study reports intergenerational inheritance of an acquired cognitive benefit and points to specific miRs as candidates mechanistically involved in this type of transmission. : Environmental enrichment (EE, a combination of physical and mental exercise, has been shown to increase cognitive abilities in mice and in humans. Benito et al. find that offspring of male mice subjected to EE also show this increase. This effect is dependent on sperm RNA and involves microRNA212/132.

    Full Text Available The maternal figure as an explicit or oblique image of the Spanish nation has undergone a good share of indignities throughout the modern cultural history of the country, from the nineteenth-century Mater Dolorosa to the stepmother of those forced into exile after the civil war, from the terrible matriarchs of Benito Peréz Galdós, Federico Garcia Lorca and Camilo José Cela to the patriarchal mothers of Spanish oppositional cinema in the final phase of the dictatorship and first years of the democratic transition. This latter avatar of the Spanish mother, so well reconstructed by Marsha Kinder, had the bewildering destiny of being both the displaced incarnation of authoritarian power and the object of the rebellion and the violent ire of her offspring. After the demise of the Franco regime, one of the most urgent tasks of the new democratic period was to produce a redefinition of the Spanish national identity, sequestered and monopolized for so many years by the ideological patchwork of the dictatorship. Towards that end, contemporary Spanish cinema has undertaken an extraordinary revision and vindication of the mother against the dire history of her evil or martyred antecedents, as a fundamental, though subtle, gesture in the attempt to rebuild, suture, and make over the nation.

    2008-01-01

    The Lower Rio Grande Valley (LRGV or Valley) in Texas, facing the big waste management challenge along the US-Mexico border today, is at the crossroads as a result of the rapid population growth, the scarcity of landfill space, the bi-nation's trade impacts, and the illusive goal of environmental sustainability. This paper offers a unique municipal solid waste investigation with regard to both physical and chemical characteristics leading to illuminate the necessary management policies with greater regional relevancy. With multiple sampling campaigns conducted during the spring of 2005, this study holistically summarizes the composition of solid waste, the statistical distribution patterns of key recyclable items, and the heating value in an uncertain environment. Research findings indicate that high fractions of plastics and paper in the waste stream imply a strong potential for energy recovery. Incineration options are thus bolstered by mildly high heating values across 10 cities in this region, which may lead to save land resources required for final disposal and increase electricity generation in the long run. Additional regression analyses further identify the correlation between recyclable items and heating value, which show that current recycling programs permit no obvious negative impacts on the incineration option. Final statistical hypothesis tests for both the Brownsville-Harlingen-San Benito and the McAllen-Edinburg-Mission metropolitan regions help foster consistent management strategies across the Valley regardless of the trivial differences of waste characteristics in between.

    Full Text Available En este artículo, se analizan las razones que motivaron a un grupo de militares encabezados por el general Francisco Antonio Aguirre a inconformarse ante el desarrollo de las elecciones para gobernador en el año de 1869 ya que los miembros de la legislatura local, no declararon gobernador constitucional electo. Ante este escenario indefinido, los militares transgredieron el orden al iniciar un pronunciamiento para externar su inconformidad. El gobierno general intervino en la vida política interna de los potosinos al ordenar a una facción del ejército regular de la federación que sofocara a los pronunciados. El movimiento político tomó otra dimensión y los sublevados redactaron un Plan político en contra del presidente Benito Juárez y sus ministros. El movimiento se mantuvo vigente al iniciar 1870 así el gobierno general envió a San Luis Potosí al general Mariano Escobedo con el propósito de restablecer a las autoridades legítimas. Luego de conseguir su objetivo, Escobedo se postuló como gobernador y ganó las elecciones en ese año.

  19. Modeling complex dispersed energy and clean water systems for the United States/Mexico border

    Herrera, Hugo Francisco Lopez

    As world population grows, and its technology evolves, the demand for electricity inexorably increases. Until now most of this electricity has been produced via fossil fuels, non-renewable energy resources that are irreversibly deteriorating our environment. On the economical aspect it does not get any better. Let's not forget market rules, the higher the demand and lower the offer, the higher the price we will have to pay. Oil is an excellent example. Some countries try to solve this situation with Pharaohnic projects, i.e. investing absurd amounts of money in 'green electricity' building monstrous dams to power equally monstrous hydroelectric power plants. The only problem with this is that it is not green at all---it does have an enormous environmental impact---it is extremely complicated and expensive to implement. It is important to point out, that this research project does not try to solve world's thirst for electricity. It is rather aimed to help solve this problematic at a much lower scale---it should be considered as an extremely small step in the right direction. It focuses on satisfying the local electricity needs with renewable, non-contaminating and locally available resources. More concisely, this project focuses on the attainment and use of hydrogen as an alternate energy source in El Paso/Juarez region. Clean technology is nowadays available to produce hydrogen and oxygen, i.e. the photoelectrolysis process. Photovoltaic cells coupled with electrolytic devices can be used to produce hydrogen and oxygen in a sustainable manner. In this research, simulation models of hybrid systems were designed and developed. They were capable to compare, predict and evaluate different options for hydrogen generation. On the other hand, with the produced hydrogen from the electrolysis process it was possible to generate electricity through fuel cells. The main objectives of the proposed research were to define how to use the resources for the attainment of hydrogen

However, dietary habits are difficult to modify and most education programs are ineffective.Design: A phenomenological qualitative study was conducted. Intentional sampling was performed in ten older persons with KO who had lost weight and improved their health-related quality of life after participating in a health education program. A thematic content analysis was conducted following the stages proposed by Miles and Huberman.Findings: Participants understood obesity as a risk factor for health problems and stigma. They believed that the cause of obesity was multifactorial and criticized health professionals for labeling them as “obese” and for assigning a moral value to slimness and diet. The factors identified as contributing to the effectiveness of the program were a tolerant attitude among health professionals, group education that encouraged motivation, quantitative dietary recommendations, and a meaningful learning model based on social learning theories.Conclusion: Dietary self-management without prohibitions helped participants to make changes in the quantity and timing of some food intake and to lose weight without sacrificing some foods that were deeply

    The 3300 km border between Mexico and the US constitutes the geopolitical separation between an underdeveloped country on the 1 hand and 1 of the most technologically and economically powerful countries in the world on the other. The border region is characterized by the contrasts on either side of the border and by the strong interrelation between both sides. Vast streams of persons, merchandise, money, services, communications, and cultural influences flow from 1 side to the other. The border region as a seat of population has a recent history. The border was defined in near current form only in the mid-19th century, when the expansionist tendencies of the US encountered a vast area of very sparse population. In 1900, the principal localities of the border zone had only about 39,000 inhabitants, of whom fewer than 5000 lived west of Ciudad Juarez. Between 1910-20, the population of the border region increased from 53,000 to 96,000 as a result of migrants fleeing the ravages of the revolution. The population of the border region was estimated at 3.826 million in 1988, resulting from rates of growth above Mexico's national average. Settlement in the area has depended on events and conditions in Mexico and on such US occurrences as Prohibition, the Great Depression, the 2nd World War, the Bracero program, and the Program of Border Industrialization. 82% of the border population lives in urban zones, partly because of lack of water. 80% of the urban population is concentrated in 6 cities, Juarez, Tijuana, Mexicali, Nuevo Laredo, Reynosa, and Matamoros. Much of the population of the 6 cities is composed of persons born elsewhere. The border area also has a large floating population of undocumented migrants in transit to or from the US. The high rates of urbanization and of binational interaction are reflected in demographic dynamics. In 1979, 71% of women in union in the border area vs 54% in the rest of Mexico had used contraception, and the infant mortality rate was

    A recent innovation of astronauts observing Earth from the International Space Station (ISS) is documenting human footprints by photographing city lights at night time. One of the earliest night-time images from the ISS was the US-Mexico border at El Paso-Ciudad Juarez. The colors, patterns and density of city lights document the differences in the cultural settlement patterns across the border region, as well as within the urban areas themselves. City lights help outline the most populated areas in settlements around the world, and can be used to explore relative population densities, changing patterns of urban/suburban development, transportation networks, spatial relationship to geographic features, and more. The data also provides insight into parameters such as surface roughness for input into local and regional climate modeling and studies of light pollution. The ground resolution of night-time astronaut photography from the ISS is typically an order of magnitude greater than current Defense Meteorological Satellite Program (DMSP) data, and therefore can serve as a "zoom lens" for selected urban areas. Current handheld digital cameras in use on the ISS, optimized for greater light sensitivity, provide opportunities to obtain new detailed imagery of atmospheric phenomena such as airglow, aurora, and noctilucent clouds in addition to documenting urban patterns. ISS astronauts have taken advantage of increasingly sensitive digital cameras to document the world at night in unprecedented detail. In addition, the capability to obtain time-lapse imagery from fixed cameras has been exploited to produce dynamic videos of both changing surface patterns around the world and atmospheric phenomena. We will profile some spectacular images of human settlements over the South-Central U.S., and contrast with other images from around the world.

    Gabriela Dutrénit

    Full Text Available From the mid-1960s, 'maquila' plants were established in the Mexican Northern border. The Mexican model was based on foreign firms establishing their own assembly plants. Even though this model was less successful than that of East and South East Asian in terms of several techno-economic indicators, it has largely contributed to employment generation. However, as a result of internal learning process and changes in the global firms strategies, several 'maquilas' operating in Mexico have undergone important qualitative changes. During the 1990s there was a change in the nature of their productive and technological activities towards more complex products and more innovative technological activities. In contrast, other dimensions have evolved slowly, such as the engagement of Mexican suppliers in global supply chains. The aim of this paper is to discuss an analytical framework to help study the technological capability accumulation in the 'maquila' industry in Mexico. Based on that the paper seeks to examine levels of technological capability accumulation of three maquilas, and to bring to light some stylized facts of the accumulation process in this industry. The analytical framework proposed draws on the taxonomy of technological capabilities proposed by Bell & Pavitt (1995 for the manufacturing industry in developing countries and its further adaptations and applications carried in Figueiredo (2001 and Ariffin & Figueiredo (2003, 2004. This paper adapts it to the particularities of the 'maquila' industry in Mexico. The new taxonomy includes technical functions that are relevant to this industry and redefines activities that correspond to various levels of accumulation. This paper is based on a case study methodology. The cases are the business lines of three maquilas in Ciudad Juarez: Thomson Multimedia, Philips Corp. and Delphi Corp. Two business lines correspond to the consumer electronics industry and the third is specialized on electronic

    One of the aerodynamic instabilities of transmission power lines cables is galloping, which consists in the appearance of important cable vibrations, mainly when the wind hits orthogonally the power line. In some cases the maximum amplitude that occurs reaches several meters, even when the wind velocities in a region are well below the value used for the mechanical design of the power lines. In general terms, galloping is associated with particular climatic conditions such as low temperatures and high humidities. In these conditions a coating of ice that adheres to the cable is formed, changing its transverse cross section, propitiating the galloping, although some authors have reported galloping without ice. These climatic conditions are presented mainly in the Northern part of our country and in the high regions of the mountain zones; nevertheless, the galloping phenomenon has been reported in few cases by Comision Federal de Electricidad (CFE). The possible expansion of the power lines in these regions of the country leads to prevent the measures needed to diminish the appearance of this phenomenon. In this paper mention is made in particular of the solution adopted to the galloping problem that has appeared in the transmission power line of Salamayuca to Reforma, Ciudad Juarez, Chihuahua (CFE,1991).

    Full Text Available Roberto Assael, Joaquin Cervantes, Gerardo Barrera Clinica Medica Internacional, Ciudad Juarez, Mexico Background: The World Health Organization estimated in 2010 that 8.8 million new tuberculosis (TB cases. About one-third of the world's population is infected and 10% will develop active TB disease. While cultures remain the international gold standard for diagnosing TB disease, in many other low-income countries, sputum smears remain the only and most accessible tool with which to diagnose active TB disease. As a consequence, in patients with TB who have negative smears, their TB remains undetected. Aim: The objective of the study reported here was to demonstrate the proportion of smear-positive/culture-positive cases compared with smear-negative/culture-positive TB cases in Mexican immigrants bound for the USA. Methods: A retrospective study was undertaken of the medical records of 122 active TB cases diagnosed at a clinic in Ciudad Juarez, Mexico, from 2009 to 2012. All cases were confirmed by culture, regardless of the sputum smear results. Results: Of the cases, 80% (97 active TB cases had negative sputum smears, while only 25 cases (20% had at least one positive smear. All of the cultures were confirmed as positive for Mycobacterium tuberculosis complex. Conclusion: The fact that 80% of the TB cases were smear negative and 20% smear positive shows that there is a clear gap between the actual state of active TB disease within patients under screening conditions, meaning that eight out of ten actual cases are being missed when sputum smear is the only diagnostic tool in asymptomatic patients with abnormal chest X-rays. Based on these results, it is highly recommended that countries that have not standardized culturing as the gold standard for the diagnosis of active TB do so, so that TB cases – which may endanger global public health – are not missed. It is also recommended that further studies be undertaken to determine the clinical

    Full Text Available Tuberculosis (TB is a major concern in developing countries. In Brazil, few genotyping studies have been conducted to verify the number of IS6110 copies present in local prevalent strains of Mycobacterium tuberculosis, the distribution and clustering of strains. IS6110 DNA fingerprinting was performed on a sample of M. tuberculosis isolates from patients with AFB smear-positive pulmonary TB, at a hospital in Brazil. The IS6110 profiles were analyzed and compared to a M. tuberculosis database of the Houston Tuberculosis Initiative, Houston, US. Seventy-six fingerprints were obtained from 98 patients. All M. tuberculosis strains had an IS6110 copy number between 5-21 allowing for differentiation of the isolates. Human immunodeficiency virus infection was confirmed in nearly half the patients of whom data was available. Fifty-eight strains had unique patterns, while 17 strains were grouped in 7 clusters (2 to 6 strains. When compared to the HTI database, 6 strains matched isolates from El Paso, Ciudad de Juarez, Houston, and New York. Recently acquired infections were documented in 19% of cases. The community transmission of infection is intense, since some clustered strains were recovered during the four-year study period. The intercontinental dissemination of M. tuberculosis strains is suspected by demonstration of identical fingerprints in a distant country.

    Full Text Available Abstract Background Previous studies have either investigated the relationship of HPV with oral cancer or the prevalence of HPV on the oral cavity. The purpose of this investigation was to study the prevalence of HPV in oral cavity of women with oral sex practices and cervical lesions. Methods Forty six (46 non-smokers and non-alcoholic patients attended the "Clínica de Displasias" of "Ciudad Juarez" were sampled. This population had a CIN diagnosis sometime between the previous six months. On previous consent they filled out a questionnaire related to their oral sex practices. Afterwards one swab from cheeks and another from palate/gum were taken; PCR was used to determine generic HPV, HPV16 and HPV18. Results Seventy two percent (72% of the patients stated to have oral sex practices regularly which all of them were positive to HPV either in oral mucus, palate/gum or both. The total of the given results showed that 35% had HPV16; among those distributed in 26% with regular oral sex practices and 9% stated as never practiced oral sex. An association was found between oral HPV16 positivity and progression to cervical CIN advanced lesions. On the other hand HPV18 was not detected. The frequency of HPV16 was higher in buccal mucosa (23% versus palate/gum (16%. Conclusions This study suggests that buccal HPV16 infection is associated with CIN progression.

    The mode of transmission of Helicobacter pylori, a bacterium causing gastric cancer and peptic ulcer disease, is unknown although waterborne transmission is a likely pathway. This study investigated the hypothesis that access to treated water and a sanitary sewerage system reduces the H. pylori incidence rate, using data from 472 participants in a cohort study that followed children in Juarez, Mexico, and El Paso, Texas, from April 1998, with caretaker interviews and the urea breath test for detecting H. pylori infection at target intervals of six months from birth through 24 months of age. The unadjusted hazard ratio comparing bottled/vending machine water to a municipal water supply was 0.71 (95% confidence interval (CI): 0.50, 1.01) and comparing a municipal sewer connection to a septic tank or cesspool, 0.85 (95% CI: 0.60, 1.20). After adjustment for maternal education and country, the hazard ratios decreased slightly to 0.70 (95% confidence interval: 0.49, 1.00) and 0.77 (95% confidence interval: 0.50, 1.21), respectively. These results provide moderate support for potential waterborne transmission of H. pylori.

    The study aim was to determine the presence of total and faecal coliforms on kitchen surfaces, in tap water and on the hands of caregivers in households on both sides of the US-Mexico border. Samples were collected in 135 randomly selected households in Ciudad Juarez, Mexico, and El Paso, Texas. Different surfaces throughout the kitchen and head of households' hands were sampled using sterile cotton swabs moistened in D/E neutralizing solution. Sponge/dishcloth and drinking water samples were also obtained. Total and faecal coliforms were enumerated on m-Endo LES and mFC respectively. Total coliforms and Escherichia coli in drinking water samples were enumerated in accordance with the Quanti-Tray method. Sponge/dishcloth samples were the most commonly contaminated kitchen sites, followed by countertops and cutting boards. We recovered faecal coliforms from 14% of the hands of child caregivers, and this indicator was moderately associated with self-reported failure to wash hands after using the toilet (OR = 3.2; 95% CI: 0.9, 11.1). Hand washing should continue to be emphasized, and additional interventions should be directed to specific kitchen areas, such as sponges/dishcloths, tables/countertops and cutting boards. There is a need for additional interventions regarding kitchen sanitation.

    To investigate the risk effects of poverty and exposure to collective violence attributed to organized crime on the mental health of children living on the United States-Mexico border. A repeated, cross-sectional study measured risk effects by comparing scores of psychosocial and behavioral problems among children and adolescents living on the border in the United States or Mexico in 2007 and 2010. Patients living in poverty who responded once to the Pictorial Child Behavior Checklist (P+CBCL) in Spanish were randomly selected from clinics in El Paso, Texas, United States (poverty alone group), and Ciudad Juarez, Chihuahua, Mexico (poverty plus violence group). Only children of Hispanic origin (Mexican-American or Mexican) living below the poverty level and presenting at the clinic for nonemergency visits with no history of diagnosed mental, neurological, or life-threatening disease or disability were included. Exposure to collective violence and poverty seemed to have an additive effect on children's mental health. Children exposed to both poverty and collective violence had higher problem scores, as measured by the P+CBCL, than those exposed to poverty alone. It is important to consider that children and adolescents exposed to collective violence and poverty also have fewer chances to receive treatment. Untreated mental health problems predict violence, antisocial behaviors, and delinquency and affect families, communities, and individuals. It is crucial to address the mental health of children on the border to counteract the devastating effects this setting will have in the short term and the near future.

    We aim to use conditional or moderated mediation to simultaneously test how and for whom an injection risk intervention was efficacious at reducing receptive needle sharing among female sex workers who inject drugs (FSWs-IDUs) in Mexico. Secondary analysis of data from a randomized trial. A total of 300 FSW-IDUs participated in Mujer Mas Segura in Ciudad Juarez, Mexico, and were randomized to an interactive injection risk intervention or a didactic injection risk intervention. We measured safe injection self-efficacy as the hypothesized mediator and policing behaviors (being arrested and syringe confiscation) as hypothesized moderators. In total, 213 women provided complete data for the current analyses. Conditional (moderated) mediation showed that the intervention affected receptive needle sharing through safe injection self-efficacy among women who experienced syringe confiscation. On average, police syringe confiscation was associated with lower safe injection self-efficacy (p = .04). Among those who experienced syringe confiscation, those who received the interactive (vs. didactic) intervention reported higher self-efficacy, which in turn predicted lower receptive needle sharing (p = .04). Whereas syringe confiscation by the police negatively affected safe injection self-efficacy and ultimately injection risk behavior, our interactive intervention helped to "buffer" this negative impact of police behavior on risky injection practices. The theory-based, active skills building elements included in the interactive condition, which were absent from the didactic condition, helped participants' self-efficacy for safer injection in the face of syringe confiscation.

    A number of activities are underway in conjunction with AVSC's Men As Partners initiative to increase men's participation in reproductive health. On March 31 and April 1, 10 reproductive health experts from across the US met at AVSC's headquarters in New York to draft a reproductive health model for men. The first model of comprehensive clinical and psychosocial services for men's reproductive health care in the country emerged from the meeting. The model includes screening services; information, education, and counseling services; and clinical diagnosis and treatment. Next steps include developing a training curriculum based upon the model and working with service providers at pilot sites throughout the US to implement the model. Elsewhere, AVSC and the International Planned Parenthood Federation have formed a partnership to work on gender and male involvement activities in Latin America. The Nippon Foundation recently awarded AVSC a grant to work in Pakistan to create, implement, and deliver high-quality men's reproductive health services in 50-60 health centers. Furthermore, AVSC has produced a short video on why clients believe male involvement in reproductive health is important; AVSC is conducting research in three districts in Kenya to identify factors which change men's reproductive health attitudes and behaviors; and AVSC and the Futures Group International are working on a pilot project to market health services to Spanish-speaking men in El Paso, Texas and Juarez, Mexico.

    Full Text Available The purpose of this research was to confirm the existence of a relationship between the immigration stay in the United States and the use of illicit drugs. By applying a nonprobabilistic sample in Tijuana, Nogales and Ciudad Juarez 567 immigrants, were interviewed 77.8% were males (average of 29 years old. The main reason of their immigration was the search for an “economic improvement”; the most of they did not have the documentation to cross the border. The main destinations were California, Arizona and Texas. When comparing the use of illicit drugs before and after the immigration experience, the number of users of cocaine and methamphetamine were found to significantly increase. The “curiosity” was the main reason to drug use, as well as the fact of being “invited by friends”. Other reasons seem to be associated to the immigration experience: some used drugs because they felt depressed or because they needed to take a break and feel relaxed after working. These findings make it possible to confirm that the immigration experience modifies the pattern of use of drugs in some immigrants who have previously used this kind of substances; some others start using them during the immigration stay.

    Full Text Available The article examines the inclusion of symbolic branding hybridization in the Mexico-United States of America border from the perspective of an open and poly significant binational region where complex processes and sometimes conflicting groups of interest and stakeholders become articulated. Using hybridization as a tool, it's possible to establish a common starting point conceiving branding within the dichotomy, as the attribute of a product that leaves a lasting impression on the minds of consumers and which turns the brand into a cultural icon directly impacting the thoughts and attitudes of people. This paper thrives to approach common knowledge of the major commercial brands that have taken root in the region of Ciudad Juarez-El Paso by contrasting the commercial culture from the per136 172 11 Vol. 21 ¿ número 41 ¿ 2012 spective of boundary and crossborder conditions.

    Northern Oaxaca terrane, southern Mexico, is bound by the Caltepec and Oaxaca faults to the west and east, respectively. These faults juxtapose the Oaxaca terrane against the Mixteca and Juarez terranes, respectively. The Oaxaca Fault also forms the eastern boundary of the Cenozoic Tehuacan depression. Several gravity profiles across these faults and the Oaxaca terrane (including the Tehuacan Valley) enables us to establish the upper crustal structure of this region. Accordingly, the Oaxaca terrane is downward displaced to the east in two steps. First the Santa Lucia Fault puts into contact the granulitic basamental rocks with Phanerozoic volcanic and sedimentary rocks. Finally, the Gavilan Fault puts into contact the Oaxaca terrane basement (Oaxaca Complex) into contact with the volcano-sedimentary infill of the valley. This gravity study reveals that the Oaxaca Fault system gives rise to a series of east tilted basamental blocks (Oaxaca Complex?). A structural high at the western Tehuacan depression accomadates the east dipping faults (Santa Lucia and Gavilan faults) and the west dipping faults of the Oaxaca Fault System. To the west of this high structural we have the depper depocenters. The Oaxaca Complex, the Caltepec and Santa Lucia faults continue northwestwards beneath Phanerozoic rocks. The faults are regional tectonic structures. They seem to continue northwards below the Trans-Mexican Volcanic Belt. A major E-W to NE-SW discontinuity on the Oaxaca terrane is inferred to exist between profiles 1 and 2. The Tehuacan Valley posses a large groundwater potential.

    The student population that is admitted to the University Juarez of Tabasco has poor healthy eating habits. Fasting glucose ≥5.6 mmol/L was found in 10% of the students. We wanted to identify the sub-pattern of their eating habits that could explain the hyperglycemia. A questionnaire on the feeding habits was applied to 3,559 first-year students, who were subjected to a blood analysis to determine biochemical markers in 2011. Based on the obtained questionnaire data, the factorial analysis was used for the statistical analysis. The Kaiser-Meyer-Olkin measure for sampling adequacy was used for validation. To determine eating habits, Varimax normalization with Kaiser was used. The number of students with euglycemia was 3,138, including 366 with values for prediabetes, and 55 with values for diabetes. After normalization using Varimax rotation with Kaiser, component 1 of participants with euglycemia included eight foods. The number of foods in component 1 of those participants with prediabetes was seven, and it diminished to four in those with fasting glucose >7 mmol/L. It was found that glucose levels increase in direct relation to the diminution in the number of selected foods.

    Full Text Available One way to explore the complexities of senses, cultures and identities is through creativity and in conversations with other artists exchanging experiences or reflecting about personal journeys. I use creative prose, poetry and image-text compositions, for example in the form of postcards or collage. Creative conversations have facilitated an understanding of this country’s complexities, and through this process I can make sense of my surroundings while sustaining a connection with places in Latin America I considered home. In this instance I invited Uruguayan painter Abigail Lutzen, trained in the Constructivist School of paint led by Torres Garcia and Tjanara Jaly Talbot, a young Indigenous woman from Sydney who supports Sydney Action for Juarez, a group that I established with other women to raise awareness about gender violence in Mexico. These are different representations of poetic and visual “feminine sensitivities” showing how we make sense of our immediate cultural environment in solidarity with others and engaging in creative collaborations as women artists.

    Bright constant light levels in the NICU may have negative effects on the growth and development of preterm infants The aim of this study is to evaluate the benefits of an alternating light/dark cycle in the NICU on weight gain and early discharge from the therapy in premature infants. A randomized interventional study was designed comparing infants in the NICU of Hospital Juarez de México, exposed from birth either to an LD environment (LD, n=19) or to the traditional continuous light (LL, n=19). The LD condition was achieved by placing individual removable helmets over the infant's heads. Body weight gain was analyzed, as the main indicator of stability and the main criteria for discharge in preterm infants born at 31.73±0.31week gestational age. Infants maintained in an LD cycle gained weight faster than infants in LL and therefore attained a shorter hospital stay, (34.37±3.12 vs 51.11±5.29days; P>0.01). Also, LD infants exhibited improved oxygen saturation and developed a daily melatonin rhythm. These findings provide a convenient alternative for establishing an LD environment for preterm healthy newborns in the NICU and confirm the beneficial effects of an alternating LD cycle for growth and weight gain and for earlier discharge time. Here we provide an easy and practical alternative to implement light/dark conditions in the NICU. Copyright © 2014 Elsevier Ltd. All rights reserved.

  2. Black carbon and polycyclic aromatic hydrocarbon emissions from vehicles in the United States-Mexico border region: pilot study.

    2006-03-01

    The investigators developed a system to measure black carbon (BC) and particle-bound polycyclic aromatic hydrocarbon (PAH) emission factors during roadside sampling in four cities along the United States-Mexico border, Calexico/Mexicali and El Paso/Juarez. The measurement system included a photoacoustic analyzer for BC, a photoelectric aerosol sensor for particle-bound PAHs, and a carbon dioxide (CO2) analyzer. When a vehicle with measurable emissions passed the system probe, corresponding BC, PAH, and CO2 peaks were evident, and a fuel-based emission factor was estimated. A picture of each vehicle was also recorded with a digital camera. The advantage of this system, compared with other roadside methods, is the direct measurement of particulate matter components and limited interference from roadside dust. The study revealed some interesting trends: Mexican buses and all medium-duty trucks were more frequently identified as high emitters of BC and PAH than heavy-duty trucks or passenger vehicles. In addition, because of the high daily mileage of buses, they are good candidates for additional study. Mexican trucks and buses had higher average emission factors compared with U.S. trucks and buses, but the differences were not statistically significant. Few passenger vehicles had measurable BC and PAH emissions, although the highest emission factor came from an older model passenger vehicle licensed in Baja California.

    Baeza Bacab, Manuel Antonio

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

    Congenital choledochal cyst (CChC) has a very low frequency in our population; it is more frequent among females and its pattern of inheritance is multifactorial. The frequency of CChC in our population was 1 per 20,000 to 1 per 30,000 hospitalized patients in the pediatrics department of the Hospital Juarez and Hospital Infantil de Tacubaya, respectively. Four new cases of CChC are reported, two school children and two teenagers. Pre-operative diagnosis was accomplished clinically, which is the most precise non-invasive method. The most effective actual diagnostic methods include ultrasonography, CAT scan, and basic laboratory data, which can corroborate the clinical diagnosis of CChC with 100% certainty. The surgical treatment of CChC is controversial, but the surgical procedures of choice are choledochocystojejunostomy with total cyst removal, Roux's Y, and cholecystectomy. One case was treated with latero-terminal choledochocystojejunostomy and 3 cases with total removal of the cyst. The results were excellent.

    FSWs who inject drugs (FSW-IDUs) can acquire HIV through high risk sexual and injection behaviors. We studied correlates of HIV infection among FSW-IDUs in northern Mexico, where sex work is quasi-legal and syringes can be legally obtained without a prescription. FSW-IDUs>18 years old who reported injecting drugs and recent unprotected sex with clients in Tijuana and Ciudad Juarez underwent surveys and HIV/STI testing. Logistic regression identified correlates of HIV infection. Of 620 FSW-IDUs, prevalence of HIV, gonorrhea, Chlamydia, trichomonas, syphilis titers ≥1:8, or any of these infections was 5.3%, 4%, 13%, 35%, 10% and 72%, respectively. Compared to other FSW-IDUs, HIV-positive women were more likely to: have syphilis titers ≥1:8 (36% vs. 9%, psocial environment (i.e., injecting drugs with clients) and policy environment (i.e., having syringes confiscated by police, attending NEPs) predominated as factors associated with risk of HIV infection, rather than individual-level risk behaviors. Interventions should target unjustified policing practices, clients' risk behaviors and HIV/STI prevention through NEPs.

    In this work the experimental results of the entrance exposition are shown and Kerma in air [mGy] in mamma obtained by irradiation of accreditation phantom of American College of Radiology (ACR). The irradiations were realized in a conventional mammography equipment of Hospital Juarez in Mexico; the technique used during the irradiations was of automatic exposition; the thickness for the phantom ACR obtained by the technique were of 4.2 and 4.5 cm; the kilo voltage pick was of 24 kV p , the time and the milli amperage per second variable. The measuring of Kerma in air was obtained with thermoluminescent dosemeters of solid state, of nano particles of zirconium dioxide prepared by the precipitation method. The dosemeters were homogenized previously in low energies of X-rays that are those used for mammography. The thermoluminescent dosemeters of ZrO 2 were calibrated by means of an ionization chamber for different expositions. The calibration curve is reported for the exposition and Kerma in air against thermoluminescent intensity obtained by reading of thermoluminescent dosemeters of ZrO 2 , as well as the technique employee for the Kerma determination in air and entrance exposition in mamma.

    Maquiladoras, manufacturing plants that primarily assemble foreign components for reexport, are located in concentrations along the northern frontier of the US/Mexico border. These plants process a wide variety of materials using modern industrial technologies within the context of developing world institutions and infrastructure. Hazardous waste generation by maquiladoras represents a critical environmental management issue because of the spatial concentration of these plants in border municipalities where the infrastructure for waste management is nonexistent or poor. These border municipalities contain rapidly increasing populations, which further stress their waste handling infrastructure capacities while exposing their populations to greater contaminant risks. Limited empirical knowledge exists concerning hazardous waste types and generation rates from maquiladorsas. There is no standard reporting method for waste generation or methodology for estimating generation rates at this time. This paper presents a method that can be used for the rapid assessment of hazardous waste generation. A first approximation of hazardous waste generation is produced for maquiladoras in the three municipalities of Nogales, Sonora, Mexicali, Baja California, and Cd. Juarez, Chihuahua, using the INVENT model developed by the World Bank. In addition, our intent is to evaluate the potential of the INVENT model for adaptation to the US/Mexico border industrial situation. The press of border industrial development, especially with the recent adoption of the NAFTA, make such assessments necessary as a basis for the environmental policy formulation and management needed in the immediate future.

    The aim of this study is to examine the spatial distribution of pedestrian injury collisions and analyse the environmental (social and physical) risk factors in Ciudad Juarez, Mexico. More specifically, this study investigates the influence of land use, density, traffic and socio-economic characteristics. This cross sectional study is based on pedestrian injury collision data that were collected by the Municipal Transit Police during 2008-2009. This research presents an analysis of vehicle-pedestrian collisions and their spatial risk determinants using mixed methods that included (1) spatial/geographical information systems (GIS) analysis of pedestrian collision data and (2) ordinary least squares (OLS) regression analysis to explain the density of pedestrian collisions data. In our model, we found a higher probability for pedestrian collisions in census tracts with population and employment density, large concentration of commercial/retail land uses and older people (65 and more). Interventions to alleviate this situation including transportation planning such as decentralisation of municipal transport system, investment in road infrastructure - density of traffic lights, pedestrian crossing, road design, improves lane demarcation. Besides, land use planning interventions should be implemented in commercial/retail areas, in particular separating pedestrian and vehicular spaces.

    Female sex workers (FSWs) experience elevated risk for HIV and sexually transmitted infections (STIs) through unprotected sex with male clients, yet the complexity of these commercial relationships remains understudied. From 2010 to 2011, we explored FSWs' conceptualizations of various client types and related risk behavior patterns using semistructured interviews with 46 FSWs in Tijuana and Ciudad Juarez, Mexico, where FSWs' HIV/STI prevalence is increasing. Our grounded theory analysis identified four types of commercial relationships: nonregular clients, regular clients and friends, clients who "fell in love" with FSWs, and long-term financial providers who often originated from the United States. As commercial relationships developed, clients' social and emotional connections to FSWs increased, rendering condom negotiation and maintaining professional boundaries more difficult. Drug abuse and poverty also influenced behaviors, particularly in Ciudad Juárez, where lucrative U.S. clients were increasingly scarce. While struggling to cultivate dependable relationships in a setting marked by historical sex tourism from a wealthier country, some FSWs ceased negotiating condom use. We discuss the need for HIV/STI research and prevention interventions to recognize the complexity within FSWs' commercial relationships and how behaviors (e.g., condom use) evolve as relationships develop through processes that are influenced by local sociopolitical contexts and binational income inequality.

    Previous studies have either investigated the relationship of HPV with oral cancer or the prevalence of HPV on the oral cavity. The purpose of this investigation was to study the prevalence of HPV in oral cavity of women with oral sex practices and cervical lesions. Forty six (46) non-smokers and non-alcoholic patients attended the "Clínica de Displasias" of "Ciudad Juarez" were sampled. This population had a CIN diagnosis sometime between the previous six months. On previous consent they filled out a questionnaire related to their oral sex practices. Afterwards one swab from cheeks and another from palate/gum were taken; PCR was used to determine generic HPV, HPV16 and HPV18. Seventy two percent (72%) of the patients stated to have oral sex practices regularly which all of them were positive to HPV either in oral mucus, palate/gum or both. The total of the given results showed that 35% had HPV16; among those distributed in 26% with regular oral sex practices and 9% stated as never practiced oral sex. An association was found between oral HPV16 positivity and progression to cervical CIN advanced lesions. On the other hand HPV18 was not detected. The frequency of HPV16 was higher in buccal mucosa (23%) versus palate/gum (16%). This study suggests that buccal HPV16 infection is associated with CIN progression.

    1996-06-01

    Full Text Available This tripartite study draws upon the vast documentation surviving from Catalonia in the tenth through twelfth centuries. It focuses in turn on the following processes, each represented by numerous surviving charters of a specific type: testamentary proof and publication (Nathaniel L. Taylor, convenientiae and agreement enforcement (Adam J. Kosto, and agrarian precaria (Pere Benito. In each case, comparison of large numbers of similar documents has enabled the construction of complex typology, not just in the traditional diplomatic sense, but also considering the function of the documents and the social causes and implications of changes in form or function. The testamentary probate documents illuminate a long-standing civil judiciary; changes in the form of the documents and the identity of testamentary authorities reflect the obsolescence and transformation of this judiciary in the eleventh and twelfth century. A case study of an eleventh-century comital conflict revealed in conventientiae shows notarial responses to changes in political behavior. Finally, agrarian precaria also follow modalities in tenurial structure. Drawing on a very rich archival resources, these findings support the relationship of social change and documentary change. Together, these studies demonstrate the nature of comparative work that can be done with studies based on large numbers of documents of superficially similar type.[fr] Cet article tripartite s'inspire de la survivance d'un grand nombre de documents catalans des Xe-XIIe siècles.

    Full Text Available OBJECTIVE: As a consequence of environmental exposure, organochlorine pesticides accumulate in lipid rich-tissues such as maternal adipose tissue and partition to maternal blood serum and umbilical blood serum. To establish their distribution in the human body, the concentration gradients of organochlorine pesticides between these compartments were determined. MATERIAL AND METHODS: Maternal adipose tissue, blood serum and umbilical blood serum samples from 64 volunteers admitted for cesarean delivery at Hospital Benito Coquet Lagunes were studied in Veracruz during 1997 and 1998. The pesticide residues were determined by gas chromatography and results obtained from different sample groups were analyzed using Pearson correlation coefficients and simple lineal regression. RESULTS: Significant results expressed on fat basis of organochlorine pesticides indicate that 1,1,1-trichloro-2,2-bis(4-chlorophenylethane (DDT levels are higher in maternal adipose tissue (4.51 mg/kg DDE and 1.27 mg/kg pp'DDT, maternal blood serum (4.45 mg/kg DDE and 0.78 mg/kg pp'DDT, and umbilical blood serum (4.70 mg/kg DDE and 0.88 mg/kg pp'DDT, due to greater affinity of DDT for lipids. CONCLUSIONS: The statistical evaluation of results and the pairing of samples analyzed indicate that absorbed organochlorine pesticides cross the placental barrier and reach a balanced state between mother and fetus.OBJETIVO: Como consecuencia de la exposición ambiental a los plaguicidas organoclorados éstos se acumulan en tejidos ricos en grasa, como el adiposo materno, y se distribuyen en el suero materno y el suero del cordón umbilical.

    sizes. The highest Qst is observed for the CMS sample having micropores sizes of about 5 A. The SWNT sample shows a lower Qst due to its relatively wide PSD [2], and the non-porous carbon black is characterized by the lowest Qst values. The Qst values calculated from H 2 adsorption isotherms measured at cryogenic temperatures below 1 atmosphere can be used to predict/estimate H 2 adsorption at ambient temperatures under high pressures. Fig 3 shows the H 2 adsorption isotherm on the SWNT sample calculated for 298 K from the low pressure and low temperature (77, 87 K) data using the Clausius-Clapeyron equation and assuming the temperature independence of the Qst values. A good agreement with high-pressure experimental data [3] is observed. Predictions using DFT model will also be discussed during presentation. [1] J. Jagiello, M. Thommes, Carbon 42, 1227, 2004.

    The paper presents a review of the Spanish needs of uranium concentrates and uranium ore processing technology and trends in Spain. Spain produces approximately 200t U 3 O 8 /a at two facilities. One plant in the south (Andujar, Jaen) can obtain 70t U 3 O 8 /a and uses a conventional acid leaching process with countercurrent solvent extraction. A second plant, situated in the west (Ciudad Rodrigo, Salamanca) has started in 1975 and has a capacity of 120-130t U 3 O 8 /a, using acid heap leaching and solvent extraction. There is another experimental facility (Don Benito, Badajoz) scheduled to start in 1976 and expected to produce about 25-35t U 3 O 8 /a as a by-product of the research work. For the near future (1978) it is hoped to increase the production with: (a) A new conventional acid leaching/solvent extraction plant in Ciudad Rodrigo; its tentative capacity is fixed at 550t U 3 O 8 /a. (b) A facility in the south, to recover about 130t U 3 O 8 /a from phosphoric acid. (c) Several small mobile plants (30t U 3 O 8 /a per plant); these will be placed near small and isolated mines. The next production increase (1979-1980) will come with the treatment of sandstones (Guadalajara and Cataluna) and lignites(Cataluna); this is being studied. There are also research programmes to study the recovery of uranium from low-grade ores (heap, in-situ and bacterial leaching) and from other industries. (author)

    To date, there is limited knowledge of the effects that abnormal sea surface temperature (SST) can have on the physiology of neonate pinnipeds. However, maternal nutritional deficiencies driven by alimentary restrictions would expectedly impact pinniped development and fitness, as an adequate supply of nutrients is essential for growth and proper functioning of all body systems, including red blood cell synthesis and clearance. Here, we investigated red blood cell morphology of California sea lion (CSL) pups from the San Benito Archipelago born during the 2014 and 2015 anomalously high SST events recorded in the northeastern Pacific Ocean. We examined whether atypical erythrocyte morphologies were more common in 2015, when the high SST event was more pronounced, and whether the stable isotope signature of pup fur, as an indicator of maternal feeding strategies, accounted for the number of atypical cells. Various atypical erythrocyte morphologies were more prevalent and more abundant than reference values. Evidence of iron deficiency was found in both years, and only pups born in 2014 showed evidence of active erythropoiesis. Microcytes and reticulocytes were more common in pups with higher isotopic δ 13 C and lower δ 15 N values, suggesting a probable relationship between maternal feeding strategies and the effect of climatic anomalies on red blood cell physiology of their pups. As developing pinnipeds require increased oxygen storage capacity for diving and foraging, the presence of atypical erythrocytes could be relevant to CSL pup fitness if the underlying cause is not reverted. This study is a first step to explore the effects that climatic alterations in the marine environment can have on the blood physiology of developing individuals.

    A study was conducted to evaluate the influence of weather (precipitation and temperature) and plant communities on grasshopper density over a 14-year period (1996-2009) in Benito Juárez County, Southern Pampas, Argentina. Total density strongly varied among plant communities. Highest values were registered in 2001 and 2003 in highly disturbed pastures and in 2002 and 2009 in halophilous grasslands. Native grasslands had the lowest density values. Seasonal precipitation and temperature had no significant effect on total grasshopper density. Dichroplus elongatus (Giglio-Tos) (Orthoptera: Acridoidea), Covasacris pallidinota (Bruner), Dichroplus pratensis Bruner, Scotussa lemniscata Stål, Borellia bruneri (Rehn) and Dichroplus maculipennis (Blanchard) comprised, on average, 64% of the grasshopper assemblages during low density years and 79% during high density years. Dichroplus elongatus, S. lemniscata and C. pallidinota were the most abundant species in 2001, 2002 and 2003, while D. elongatus, B. brunneri and C. pallidinota in 2009. Dichroplus elongatus and D. pratensis, mixed feeders species, were positively affected by summer rainfall. This suggests that the increase in summer precipitation had a positive effect on the quantity and quality forage production, affecting these grasshopper populations. Scotussa lemniscata and C. pallidinota were negatively affected by winter and fall temperature, possibly affecting the embryonic development before diapause and hatching. Dichroplus elongatus and D. pratensis were associated with highly disturbed pastures, S. lemniscata with pastures and B. bruneri and D. maculipennis with halophilous grasslands. Covasacris pallidinota was closely associated with halophilous grasslands and moderately disturbed pastures. Weather conditions changed over the years, with 2001, 2002 and 2003 having excessive rainfall while 2008 and 2009 were the driest years since the study started.

  3. Subsurface geometry of the San Andreas-Calaveras fault junction: influence of serpentinite and the Coast Range Ophiolite

    While an enormous amount of research has been focused on trying to understand the geologic history and neotectonics of the San Andreas-Calaveras fault (SAF-CF) junction, fundamental questions concerning fault geometry and mechanisms for slip transfer through the junction remain. We use potential-field, geologic, geodetic, and seismicity data to investigate the 3-D geologic framework of the SAF-CF junction and identify potential slip-transferring structures within the junction. Geophysical evidence suggests that the San Andreas and Calaveras fault zones dip away from each other within the northern portion of the junction, bounding a triangular-shaped wedge of crust in cross section. This wedge changes shape to the south as fault geometries change and fault activity shifts between fault strands, particularly along the Calaveras fault zone (CFZ). Potential-field modeling and relocated seismicity suggest that the Paicines and San Benito strands of the CFZ dip 65° to 70° NE and form the southwest boundary of a folded 1 to 3 km thick tabular body of Coast Range Ophiolite (CRO) within the Vallecitos syncline. We identify and characterize two steeply dipping, seismically active cross structures within the junction that are associated with serpentinite in the subsurface. The architecture of the SAF-CF junction presented in this study may help explain fault-normal motions currently observed in geodetic data and help constrain the seismic hazard. The abundance of serpentinite and related CRO in the subsurface is a significant discovery that not only helps constrain the geometry of structures but may also help explain fault behavior and the tectonic evolution of the SAF-CF junction.

    Full Text Available Javier Ena, Concepción Amador, Conxa Benito, Francisco PasquauHIV Unit, Hospital Marina Baixa, Villajoyosa, SpainAbstract: We reviewed the current information available on nevirapine immediate- and extended-release formulations and its role in single-dose and combination antiretroviral therapy. Nevirapine was approved in 1996 and was the first non-nucleoside reverse-transcriptase inhibitor available for the treatment of HIV-1 infection. Nevirapine has demonstrated good efficacy and a well-characterized safety profile. A major drawback is the low genetic barrier, allowing the emergence of resistance in the presence of single mutations in the reverse-transcriptase gene. This shortcoming is particularly relevant when nevirapine is administered in a single dose to prevent mother-to-child transmission of HIV-1 infection, compromising the efficacy of future non-nucleoside reverse transcriptase–inhibitor regimens. Studies published recently have probed the noninferiority of nevirapine compared to ritonavir-boosted atazanavir with both tenofovir disoproxil fumarate and emtricitabine in antiretroviral treatment–naïve patients. In 2011, a new formulation of nevirapine (nevirapine extended release that allowed once-daily dosing was approved by the Food and Drug Administration and by the European Medicines Agency. VERxVe, a study comparing nevirapine extended release with nevirapine immediate release in antiretroviral treatment–naïve patients, and TRANxITION, a study carried out in antiretroviral treatment–experienced patients who switched therapy from nevirapine immediate release to nevirapine extended release, provided data on the noninferiority of the new formulation of nevirapine compared with nevirapine immediate release in terms of efficacy and safety. Nevirapine extended release will further increase the durability and persistence of nevirapine-containing antiretroviral therapy, allowing once-daily dosing regimens.Keywords: nevirapine

    All the 50 years of conscious pondering did not bring me nearer to an answer to the question `what is light quanta?'. Nowadays, every rascal believes, he knows it, however, he is mistaken. (A Einstein, 1951 in a letter to M Besso) Quantum optics has played a key role in physics in the last several decades. On the other hand, in these early decades of the information age, the flow of information is becoming more and more central to our daily life. Thus, the related fields of quantum information theory as well as Bose-Einstein condensation have acquired tremendous importance in the last couple of decades. In Quantum Optics III, a fusion of these fields appears in a natural way. Quantum Optics III was held in Pucón, Chile, in 27-30 of November, 2006. This beautiful location in the south of Chile is near the lake Villarrica and below the snow covered volcano of the same name. This fantastic environment contributed to a relaxed atmosphere, suitable for informal discussion and for the students to have a chance to meet the key figures in the field. The previous Quantum Optics conferences took place in Santiago, Chile (Quantum Optics I, 2000) and Cozumel, Mexico (Quantum Optics II, 2004). About 115 participants from 19 countries attended and participated in the meeting to discuss a wide variety of topics such as quantum-information processing, experiments related to non-linear optics and squeezing, various aspects of entanglement including its sudden death, correlated twin-photon experiments, light storage, decoherence-free subspaces, Bose-Einstein condensation, discrete Wigner functions and many more. There was a strong Latin-American participation from Argentina, Brazil, Chile, Colombia, Peru, Uruguay, Venezuela and Mexico, as well as from Europe, USA, China, and Australia. New experimental and theoretical results were presented at the conference. In Latin-America a quiet revolution has taken place in the last twenty years. Several groups working in quantum optics and

    This shaded relief image of Mexico's Yucatan Peninsula show a subtle, but unmistakable, indication of the Chicxulub impact crater. Most scientists now agree that this impact was the cause of the Cretatious-Tertiary Extinction, the event 65 million years ago that marked the sudden extinction of the dinosaurs as well as the majority of life then on Earth.Most of the peninsula is visible here, along with the island of Cozumel off the east coast. The Yucatan is a plateau composed mostly of limestone and is an area of very low relief with elevations varying by less than a few hundred meters (about 500 feet.) In this computer-enhanced image the topography has been greatly exaggerated to highlight a semicircular trough, the darker green arcing line at the upper left corner of the peninsula. This trough is only about 3 to 5 meters (10 to 15 feet) deep and is about 5 km. wide (3 miles), so subtle that if you walked across it you probably would not notice it, and is a surface expression of the crater's outer boundary. Scientists believe the impact, which was centered just off the coast in the Caribbean, altered the subsurface rocks such that the overlying limestone sediments, which formed later and erode very easily, would preferentially erode on the vicinity of the crater rim. This formed the trough as well as numerous sinkholes (called cenotes) which are visible as small circular depressions.Two visualization methods were combined to produce the image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction, so that northwestern slopes appear bright and southeastern slopes appear dark. Color coding is directly related to topographic height, with green at the lower elevations, rising through yellow and tan, to white at the highest elevations.For a smaller, annotated version of this image, please select Figure 1, below: [figure removed for brevity, see original site] (Large image: 1.5 m

MATERIAL AND METHODS: Between February and April 2005, IDUs were recruited in Tijuana (N=222 and Ciudad Juarez (N=206 using respondent-driven sampling (RDS, a chain referral sampling approach. Interviewer-administered questionnaires assessed drug-using behaviors during the prior six months. Venous blood was collected for immunoassays to detect HIV and HCV antibodies. For HIV, Western blot or immunofluorescence assay was used for confirmatory testing. Final HCV antibody prevalence was estimated using RDS adjustments. RESULTS: Overall, HCV and HIV prevalence was 96.0% and 2.8%, respectively, and was similar in both cities. Most IDUs (87.5% reported passing on their used injection equipment to others, and 85.9% had received used equipment from others. CONCLUSIONS: HIV prevalence was relatively high given the prevalence of HIV in the general population, and HCV prevalence was extremely high among IDUs in Tijuana and Ciudad Juarez. Frequent sharing practices indicate a high potential for continued transmission for both infections. HCV counseling and testing for IDUs in Mexico and interventions to reduce sharing of injection equipment are needed.OBJETIVO: Estimar las prevalencias de los virus de hepatitis C (VHC y de VIH y los comportamientos de riesgo asociados con ellos, entre usuarios de drogas inyectables (UDI en dos ciudades del norte de México.

    This paper describes the performance of a solar dryer capable of bacterial pathogen removal from the physicochemical sludge of the main wastewater treatment plant for Ciudad Juarez, Mexico. The solar setup was proposed as an alternative solution, technically feasible, for reducing the volume of the 135 tons of sludge produced per day in this plant. The experimental-greenhouse prototype has a 4.5 m{sup 2} collection area, a 1 m{sup 3}-drying bed, and automatic systems for ventilation, extraction, and data acquisition. The automatic operation was controlled by temperature and humidity differences between internal and external conditions. Global solar radiation, pH and water content of the sludge were monitored. The overall effectiveness of the solar dryer was determined by assessing thermal and microbiological performance. Water content in sludge during the process was used as an indicator of thermal effectiveness. The microbiological elimination was quantified at different residence times considering two contamination indicators: faecal coliforms and Salmonella spp. Quantification of the pathogenic microorganisms was carried out by the multiple-tube fermentation technique presented in the Mexican regulation NOM-004-SEMARNAT-2002. The thermal results related to the water content showed an exponential decay that achieved up to a 99 % reduction. Regarding microbiological removal effectiveness, there was a strong dependence between the number of bacteria present and the water content in the sludge. As a consequence, with the removal of 92 % of water, it was verified that the elimination of faecal coliforms fell from 3.8x10{sup 6} to 1.6 MPN per gram of dried sludge; and for Salmonella spp. the reduction was from 1.5x10{sup 1}3 to 1.9x10{sup 3} MPN per gram of dried sludge.

    Three unsaturated profiles were obtained from Mesilla Bolson and Guaymas aquifer systems, northern Mexico. About 500 mL of undisturbed soil from depths between 1 m and 58 m below the surface were obtained every meter by dry percussion from a borehole located near Cd Juarez, Chihuahua state. The other two boreholes were located in the southwestern portion of Sonora state; about 500 mL of undisturbed soil from depths 0-5.50 and 0- 8.50 m were obtained every 0.25 m by dry drilling at Narciso Mendoza and Guaymas sites, respectively. Samples were contained in sealed glass jars and analyzed for moisture content, chloride, deuterium and nitrate (NO 3 -N). The interstitial water was extracted by elution; chloride and nitrate were determined by automated colorimetry while deuterium by direct reduction. Considering an average precipitation at Mesilla Bolson area of 230 mm/year, a chloride rain content of 1 mg/L and a mean Cl content on the unsaturated profile of 977 mg/L below the zero flux plane, we estimated by the Cl mass balance approach a net palaeorecharge in the area of about 0.24 mm/year with a probable time scale profile of 11,000 years. For the Guaymas area the net recharge is in the range 0.11-0.16 mm/year, assuming an average rainfall of 320 mm/year, Cl rainfall content of 3.4 mg/L and mean Cl concentrations on the profiles of 6,939 and 9,470 mg/L below the zero flux plane, respectively.

    Interest in passive wireless sensing has grown over the past few decades to meet demands in structural health monitoring.(Deivasigamani et al., 2013; Wilson and Juarez, 2014) This work describes a passive wireless sensor for monitoring strain, which does not have an embedded battery or chip. Without an embedded battery, the passive wireless sensor has the potential to maintain its functionality over long periods in remote/harsh environments. This work also focuses on monitoring small strain (less than 1000 micro-?). The wireless sensing system includes a reader unit, a coil-like transponder, and a sensing unit. It operates in the Megahertz (MHz) frequency range, which allows for a few centimeters of separation between the reader and sensing unit during measurements. The sensing unit is a strain-sensitive piezoelectric resonator that maximizes the energy efficiency at the resonance frequency, so it converts nanoscale mechanical variations to detectable differences in electrical signal. In response to an external loading, the piezoelectric sensor breaks from its original electromechanical equilibrium, and the resonant frequency shifts as the system reaches a new balanced equilibrium. In this work, the fixture of the sensing unit is a small, sticker-like package that converts the surface strain of a test material to measurable shifts in resonant frequencies. Furthermore, electromechanical modeling provides a lumped-parameter model of the system to describe and predict the measured wireless signals of the sensor. Detailed characterization demonstrates how this wireless sensor has resolution comparable to that of conventional wired strain sensors for monitoring small strain.

    A higher incidence of infectious disease has been documented in U.S. regions bordering Mexico compared with non-border areas. We assessed the prevalence of important gastrointestinal infections in Ciudad Juarez, Mexico, and El Paso, Texas, the largest binational community along the U.S.-Mexico border. Fecal specimens from a sample of the asymptomatic population representing all ages were tested for Helicobacter pylori (H. pylori), Cryptosporidium spp., Giardia spp., and other intestinal parasitic pathogens using flotation, immunoassays, and/or polymerase chain reaction. We also measured indicators of microbiological contamination of drinking water, hands of food preparers, and kitchen surfaces. Overall, of the 386 participants, H. pylori was present in 38.2%, Taenia spp. in 3.3%, Giardia spp. in 2.7%, Cryptosporidium spp. in 1.9%, Entamoeba dispar in 1.3%, and Ascaris lumbricoides and Necator americanus in 0.3% of the study subjects; Cyclospora spp. and Entamoeba histolytica were not found. H. pylori infection was associated with handwashing (prevalence ratio [PR] = 1.3, 95% confidence interval [CI] 1.0, 1.8). Taenia spp. was found more often on the U.S. side (PR=8.6, 95% CI 2.3, 30.8). We did not find an association between these infections and the occurrence of total coliforms or fecal coliforms on kitchen surfaces. In addition, Escherichia coli was not found in any drinking water sample. The study results indicated that H. pylori and Taenia spp. infections may be highly prevalent along the U.S.-Mexico border. Additional research is necessary to adequately characterize the prevalence, as well as determine whether interventions that reduce these infections are warranted.

    In order to reduce cardiovascular disease risk factors, a healthy diet must include dietary antioxidants from different sources (eg, Spirulina maxima ) and regular practice of exercise should be promoted. There is some evidence from animal studies that S. maxima and exercise decrease cardiovascular disease risks factors. However, very few studies have proved the independent or synergistic effect of S. maxima plus exercise in humans. This study attempts to address the independent and synergistic effects in overweight and obese subjects participating in a systematic physical exercise programme at moderate intensity on general fitness, plasma lipid profile and antioxidant capacity. Using a randomised, double-blind, placebo-controlled, counterbalanced crossover study design, 80 healthy overweight and obese subjects will be evaluated during a 12-week isoenergetic diet accompanied by 4.5 g/day S. maxima intake and/or a physical systematic exercise programme at moderate intensity. Body composition, oxygen uptake, heart rate, capillary blood lactate, plasma concentrations of triacylglycerols, total, low-density and high-density lipoprotein cholesterol, antioxidant status, lipid oxidation, protein carbonyls, superoxide dismutase, catalase, glutathione, glutathione peroxidase, glutathione reductase and paraoxonase will be assessed. This study and all the procedures have been approved by the Universidad Autonoma de Ciudad Juarez Bioethics Committee.

    Full Text Available Deborah Taira Juarez, Kendra M Demaris, Roy Goo, Christina Louise Mnatzaganian, Helen Wong SmithDaniel K Inouye College of Pharmacy, University of Hawaii at Hilo, Honolulu, HI, USAAbstract: The 2014 American Diabetes Association guidelines denote four means of diagnosing diabetes. The first of these is a glycosylated hemoglobin (HbA1c >6.5%. This literature review summarizes studies (n=47 in the USA examining the significance, strengths, and limitations of using HbA1c as a diagnostic tool for diabetes, relative to other available means. Due to the relatively recent adoption of HbA1c as a diabetes mellitus diagnostic tool, a hybrid systematic, truncated review of the literature was implemented. Based on these studies, we conclude that HbA1c screening for diabetes has been found to be convenient and effective in diagnosing diabetes. HbA1c screening is particularly helpful in community-based and acute care settings where tests requiring fasting are not practical. Using HbA1c to diagnose diabetes also has some limitations. For instance, HbA1c testing may underestimate the prevalence of diabetes, particularly among whites. Because this bias differs by racial group, prevalence and resulting estimates of health disparities based on HbA1c screening differ from those based on other methods of diagnosis. In addition, existing evidence suggests that HbA1c screening may not be valid in certain subgroups, such as children, women with gestational diabetes, patients with human immunodeficiency virus, and those with prediabetes. Further guidelines are needed to clarify the appropriate use of HbA1c screening in these populations.Keywords: diabetes mellitus, diagnosis, glycosylated hemoglobin, USA

    Emission inventories of ozone precursors are routinely used as input to comprehensive photochemical air quality models. Photochemical model performance and the development of effective control strategies rely on the accuracy and representativeness of an underlying emission inventory. This paper describes the tasks undertaken to compile and evaluate an ozone precursor emission inventory for the El Paso/Ciudad Juarez/Southern Dona Ana region. Point, area and mobile source emission data were obtained from local government agencies and were spatially and temporally allocated to a gridded domain using region-specific demographic and land-cover information. The inventory was then processed using the US Environmental Protection Agency (EPA) recommended Emissions Preprocessor System 2.0 (UAM-EPS 2.0) which generates emissions files compatible with the Urban Airshed Model (UAM). A top-down evaluation of the emission inventory was performed to examine how well the inventory represented ambient pollutant compositions. The top-down evaluation methodology employed in this study compares emission inventory ratios of non-methane hydrocarbon (NMHC)/nitrogen oxide (NO{sub x}) and carbon monoxide (CO)/NO{sub x} ratios to corresponding ambient ratios. Detailed NMHC species comparisons were made in order to investigate the relative composition of individual hydrocarbon species in the emission inventory and in the ambient data. The emission inventory compiled during this effort has since been used to model ozone in the Paso del Norte airshed (Emery et al., CAMx modeling of ozone and carbon monoxide in the Paso del Norte airshed.

    The Dietary Supplements and Health Education Act (DSHEA), passed by the United States Congress in October of 1994, defines herbal products as nutritional supplements, not medications. This opened the market for diverse products made from plants, including teas, extracts, essential oils, and syrups. Mexico and the United States share an extensive border, where diverse herbal products are available to the public without a medical prescription. Research undertaken in the neighboring cities of Ciudad Juarez, Mexico, and El Paso, Texas, USA, shows the use of herbs is higher in this border area compared to the rest of the United States. A portion of the population is still under the erroneous impression that "natural" products are completely safe to use and therefore lack side effects. We review the dangers of ingesting the toxic seed of Thevetia spp. (family Apocynaceae), commonly known as "yellow oleander" or "codo de fraile," misleadingly advertised on the Internet as an effective and safe dietary supplement for weight loss. Lack of proper quality control regarding herbs generates a great variability in the quantity and quality of the products' content. Herb-drug interactions occur between some herbal products and certain prescription pharmaceuticals. Certain herbs recently introduced into the U.S. market may not have been previously tested adequately for purity, safety, and efficacy. Due to the lack of reliable clinical data regarding the safe use of various herbal products currently available, the public should be made aware regarding the possible health hazards of using certain herbs for therapeutic purposes. The potentially fatal toxicity of yellow oleander seed is confirmed by cases reported from various countries, while the purported benefits of using it for weight loss have not been evaluated by any known clinical trials. For this reason, the use of yellow oleander seed as a dietary supplement should be avoided.

    To investigate individual, interpersonal, and social-structural factors associated with involuntary sex exchange among female sex workers (FSWs) along the Mexico-U.S. border. In 2010 to 2011, 214 FSWs from Tijuana (n = 106) and Ciudad Juarez (n = 108) aged ≥ 18 years who reported lifetime use of heroin, cocaine, crack, or methamphetamine, having a stable partner, and having sold/traded sex in the past month completed quantitative surveys and HIV/sexually transmitted infection testing. Logistic regression was used to identify correlates of involuntary sex exchange among FSWs. Of 214 FSWs, 31 (14.5%) reported involuntary sex exchange These women were younger at sex industry entry [adjusted odds ratio (AOR): 0.84/1-year increase, 95% confidence interval (CI): 0.72 to 0.97] and were significantly more likely to service clients whom they perceived to be HIV/sexually transmitted infection-infected (AOR: 12.41, 95% CI: 3.15 to 48.91). In addition, they were more likely to have clients who used drugs (AOR: 7.88, 95% CI: 1.52 to 41.00), report poor working conditions (AOR: 3.27, 95% CI: 1.03 to 10.31), and report a history of rape (AOR: 4.46, 95% CI: 1.43 to 13.91). Involuntary sex exchange is disproportionate among FSWs who begin to exchange sex at a younger age, and these women experience elevated risk of violence and HIV/STIs related to their clients' behaviors and their working conditions. These data suggest the critical need for evidence-based approaches to preventing sexual exploitation of women and girls and to reducing harm among current sex workers. Multilevel interventions for all females who exchange sex and their clients that target interpersonal and social-structural risks (eg, measures to improve safety and reduce exploitation within the workplace) are needed.

    Aims To examine the impact of migration to the US on substance use and substance use disorders in three urban areas of Northern Mexico. Design Cross-sectional survey of immigration related experiences and lifetime and past-year alcohol and drug use, in a representative sample of respondents ages 12 to 65. Setting Interviews were conducted in the cities of Tijuana, Ciudad Juarez, and Monterrey during 2005. Respondents were classified into three groups: 1) “return migrants”, 2) “relatives of migrants” and 3) “others in the general population”. Findings A total of 1,630 completed interviews were obtained for a response rate of 70.5%. “Return migrants” were more likely to have used alcohol, marijuana or cocaine at least once in their lifetime and in the last 12-months, more likely to develop a substance use disorder, and more likely to have a 12-month substance use disorder, compared with “others in the general population”. Among “return migrants”, longer length of time in the US and type of work performed as an immigrant were related to higher prevalence of substance use. Among “relatives of migrants”, migration experiences were not associated with increased prevalence of substance use compared with “others in the general population”. Conclusion This study found a link between migration to the US and the transformation of substance use norms and pathology in Mexico. Future research of pre-migration involvement in substance use and data on the timing of events among return migrants is needed. Public health measures are likely to require cross-border coordination of research and service development. PMID:19215601

Hay efecto combinado de guerra entre cárteles por el control de la plaza, que se mezcla con la mala estrategia de enfrentamiento y la penetración de los cuerpos policíacos, lo que da como resultado una amplia destrucción de personas, familias y espacios. Las violencias se construyen porque hay causas estructurales, como el modelo de ciudad, porque hay una deficiente presencia del Estado y por una estrategia de guerra entre cárteles. Todo esto produce la crisis de violencia que se vive en Ciudad Juárez.   Abstract   This paper provides an analysis of the different types of violence that are generated in the crisis of a city that was shot down by drug gangs in Mexico’s border with the United States. The combined effects of the war between cartels for control of the square, mixed with the bad strategy of confrontation and the penetration of the police forces give as a result extensive destruction of individuals, families and spaces. Violence is built because there are structural causes such as the city’s model, because there is a weak State presence and war strategy between cartels. All this results in the violence crisis that exists in Ciudad Juarez.

    The state of Chihuahua counts with at least 56 uranium zones or of minerals associated to this, being Pena Blanca the greatest and more important deposit of the country. Some of the main cities of the state are near to these deposits, as Aldama and Chihuahua. Its were took samples of soil of 11 cities of the state to determine the natural activity of radionuclides. It was determined the specific activity attributable to the parents of the series of 238 U, 232 Th, and of the 40 K isotopes, as well as effective dose rate H E in the soil samples. It was used the high resolution gamma spectrometry of a high purity Ge detector in the laboratory of Environmental Radiological Surveillance of the CIMAV. The measure of the activity of the uranium series carries out by means of the lines of 351 KeV of the 214 Pb and of 609 keV of the 214 Bi, while the thorium series it was deduced of the lines of 238 keV of the 212 Pb and of 912 keV of the 228 Ac. Its were carried out copies and replies for the quality control. Its were found high values of specific activity of some radionuclides, in the near cities to uranium deposits like Aldama and Chihuahua. For the cities that are not near to deposits, as Ciudad Juarez and Ojinaga, the found values were normal. Also the effective dose rate was high for the near cities to deposits like Aldama, Bocoyna, Chihuahua, Jimenez and Nuevo Casas Grandes, it is also necessary to determine, the radon in air levels and of radionuclides in consumption water to obtain the dose that the population of those populations receives.

    Glyphosate is a worldwide used herbicide as c. 90% of transgenic crops are tolerant to it. Microbial degradation of glyphosate molecule in soil is considered the most important process that determines its persistence in the environment. However, the impact of this herbicide on target groups of soil biota remains poorly understood. Our objective was to characterize the abundance of bacterial groups and global microbial activity, under controlled conditions with application of increasing doses of glyphosate. A bioassay was carried out in microcosms using an agricultural soil (Typic Argiudoll) with registered history of glyphosate application from National Institute of Agricultural Technology (INTA, EEA Marcos Juarez, Argentina). Glyphosate of commercial formulation (74.7%) was used and the following treatments were evaluated: Soil without glyphosate (control), and Soil with doses equivalent to 1.12 and 11.2 kg ai ha-1. Microbiological parameters were estimated at 3, 7, 14 and 21 days after herbicide application by counting heterotrophic, cellulolytic, nitrogen fixing (N), and nitrifying bacteria; and fluorescein diacetate hydrolysis (FDA), microbial respiration (MR) and microbial biomass (C-BM). The N cycle related bacteria showed greater sensitivity to glyphosate with significant increases in abundance. On the other hand the C cycle parameters were strongly conditioned by the time elapsed since the application of the herbicide, as did the MR. The FDA declined with the highest dose, while the C-BM was not affected. Therefore, we conclude that in the studied experimental conditions glyphosate stimulated bacterial growth (i.e. target abundances) representing a source of N, C and nutrients. On the other hand, enzymatic activity (FDA) decreased when glyphosate was applied in the highest dose, whereas, it had no effect on the MR nor C-BM, which could be attributable to the organic matter content of the soil. However, future research in field conditions is necessary, for

    Enhancements in ozone were observed between about 3 and 10 km altitude within an electrically active storm in central New Mexico. Measurements from satellite sensors and ground-based radar show cloud top pressures between 300 and 150 mb in the vicinity of an ozonesonde launched from Socorro, NM, and heavy precipitation with radar reflectivities exceeding 50 dBZ. Data from a lightning mapping array and a surface electric field mill show a large amount of electrical activity within this thunderstorm. The observed ozone enhancements are large (50% above the mean) and could have resulted from a number of possible processes, including the advection of polluted air from the urban environments of El Paso and Juarez, photochemical production by lightning-generated NOx from aged thunderstorm outflow, downward mixing of stratospheric air, or local production from within the thunderstorm. We find that a large fraction of the ozone enhancement is consistent with local production from corona discharges, either from cloud particles or by corona associated with lightning. The implied global source of ozone from thunderstorm corona discharge is estimated to be 110 Tg O3 a-1 with a range between 40 and 180 Tg O3 a-1. This value is about 21% as large as the estimated ozone production rate from lightning NOx, and about 3% as large as the total chemical production rate of tropospheric ozone. Thus while the estimated corona-induced production of ozone may be significant on local scales, it is unlikely to be as important to the global ozone budget as other sources.

    The state of Chihuahua counts with at least 56 uranium zones or of minerals associated to this, being Pena Blanca the greatest and more important deposit of the country. Some of the main cities of the state are near to these deposits, as Aldama and Chihuahua. Its were took samples of soil of 11 cities of the state to determine the natural activity of radionuclides. It was determined the specific activity attributable to the parents of the series of {sup 238} U, {sup 232} Th, and of the {sup 40} K isotopes, as well as effective dose rate H{sub E} in the soil samples. It was used the high resolution gamma spectrometry of a high purity Ge detector in the laboratory of Environmental Radiological Surveillance of the CIMAV. The measure of the activity of the uranium series carries out by means of the lines of 351 KeV of the {sup 214} Pb and of 609 keV of the {sup 214} Bi, while the thorium series it was deduced of the lines of 238 keV of the {sup 212} Pb and of 912 keV of the {sup 228} Ac. Its were carried out copies and replies for the quality control. Its were found high values of specific activity of some radionuclides, in the near cities to uranium deposits like Aldama and Chihuahua. For the cities that are not near to deposits, as Ciudad Juarez and Ojinaga, the found values were normal. Also the effective dose rate was high for the near cities to deposits like Aldama, Bocoyna, Chihuahua, Jimenez and Nuevo Casas Grandes, it is also necessary to determine, the radon in air levels and of radionuclides in consumption water to obtain the dose that the population of those populations receives.

    The Gulf of California is resulting from an oblique-rift system due to the separation of the Pacific and the North American plates in the ~N110E to ~N125E trend. The age, nature and orientation of strain which ended with continental break-up and incipient oceanization at ~3.6 Ma, is largely misunderstood. It is generally proposed that early stages of extension began at around 12 Ma with strain partitioning into two components: a pure ENE directed extension in the Gulf Extensional Province (which includes Sonora and the eastern Baja California Peninsula in Mexico) and a dextral strike-slip displacement west of the Baja California Peninsula along the San Benito and Tosco-Abreojos faults. This evolution would have lasted ~5-6 Ma when a new transtensional strain regime took place. This regime, with extension trending ~N110E +/-10° , led to the final break-up and the subsequent individualization of a transform-fault system and subordoned short oceanic ridges. This two-steps interpretation has recently been challenged by authors suggesting a continuous transtensional extension from 12Ma in the trend of the PAC-NAM plates Kinematic. We question both of those models in term of timing and mode of accommodation basing ourselves on field investigations in Baja California Sur (Mexico). The volcano-sedimentary formations of the Comondù group dated 25 to 20 Ma exhibit clear examples of syn-sedimentary and syn-magmatic extensive deformations. This extension, oriented N65° E+/-15° , is proposed to initiate during the Magdalena Plate subduction. It would be related to the GOC initialization. In addition to this finding, we present tectonic and dating evidences of complex detachment-faulting tectonics varying in trend and kinematics with time and space for the development to the south of Baja California Sur. The extension associated with the early detachment-fault system trended ~N110E. From ~17 Ma to, probably, ~7-8 Ma, this extension controlled the early development of the San

However, cholera continues to cause extensive suffering and needless deaths across the country, particularly among the poor. The urgent need to eliminate transmission of cholera persists: compared to the same period in 2014, the first 4 months of 2015 saw three times the number of cholera cases. Drawing upon epidemiology, clinical work (and clinical knowledge, policy, ecology, and political economy, and informed by ethnographic data collected in a rural area of Haiti called Bocozel, this paper evaluates the progress of the nation's 10-year Plan for the Elimination of Cholera. Bocozel is a rice-producing region where most people live in extreme poverty. The irrigation network is decrepit, the land is prone to environmental shocks, fertilizer is not affordable, and the government's capacity to assist farmers is undermined by resource constraints. When peasants do have rice to sell, the price of domestically grown rice is twice that of US-imported rice. Canal water is not only used to irrigate thousands of acres of rice paddies and sustain livestock, but also to bathe, wash, and play, while water from wells, hand pumps, and the river is used for drinking, cooking, and bathing.

    Full Text Available In this essay, we will try a certain approach to the intangible aspects of rural development, a contribution to the knowledge of idiosyncrasy of people living in rural areas, studying the perceptions and bearings of young people that live or dwell in rural areas in Extremadura. Deep changes taking place in rural environment bring about a new set of values and beliefs towards the future. We would like to find out whether the apprehension of life that young people of rural extraction show is turning to a fresh set of values apprising non-material advantages of the rural environment. In fact, our target is to find out their spirits and their perception of the possibility that, regardless of the demographic decline in rural areas, villages would come up again. In short, we state in this essay some approaches to the following topics: the level of concern about the problems regarding rural environment, the symbolic insight into rural life, the upbringing of youngsters under a new set of values, their labour and carrier expectancies and life prospects for young students of rural extraction.Este artículo trata de exponer una manera de abordar los aspectos intangibles en el desarrollo rural, es decir, una contribución al conocimiento de la mentalidad de los que habitan en el medio rural a través de las percepciones y orientaciones de los jóvenes estudiantes rurales de Extremadura. Las transformaciones que afectan al medio rural introducen nuevos órdenes de valores y creencias de cara al futuro. Se trata de saber si las valoraciones de los jóvenes de los pueblos están girando hacia el nuevo paradigma de la funcionalidad no material del medio rural. En última instancia, se trata de conocer su estado de ánimo de cara al futuro y si comienza a valorarse la posibilidad de recuperación de los pueblos pese al declive de las zonas rurales de las últimas décadas (González J.

    The results from seismic hazard studies carried out in two seismic scenarios, Central America Region (CA) and La Hispaniola Island, are presented here. Both cases follow the Probabilistic Seismic Hazard Assessment (PSHA) methodology and they are developed in terms of PGA, and SA (T), for T of 0.1, 0.2, 0.5, 1 and 2s. In both anaysis, hybrid zonation models are considered, integrated by seismogenic zones and faults where data of slip rate and recurrence time are available. First, we present a new evaluation of seismic hazard in CA, starting with the results of a previous study by Benito et al (2011). Some improvements are now included, such as: updated catalogue till 2011, corrections in the zonning model in particular for subduction regime taken into account the variation of the dip in Costa Rica and Panama, and modelization of some faults as independent units for the hazard estimation. The results allow us to carry out a sensitivity analysis comparing the ones obtained with and without faults. In a second part we present the results of the PSHA in La Hispaniola, carried out as part of the cooperative project SISMO-HAITI supported by UPM and developed in cooperation with ONEV. It started a few months after the 2010 event, as an answer to a required help from the Haitian government to UPM. The study was aimed at obtaining results suitable for seismic design purposes and started with the elaboration of a seismic catalogue for the Hispaniola, requiring an exhaustive revision of data reported by around 30 seismic agencies, apart from these from Puerto Rico and Dominican Republic Seismic Networks. Seismotectonic models for the region were reviewed and a new regional zonation was proposed, taking into account different geophysical data. Attenuation models for subduction and crustal zones were also reviewed and the more suitable were calibrated with data recorded inside the Caribbean plate. As a result of the PSHA, different maps were generated for the quoted parameters

    Central America (CA) is known as a seismically active region in which several historic destructive earthquakes have occurred. This fact has promoved the development of seismic hazard studies that provide necessary estimates for decision making and risk assessment efforts, requiring a complete and standardized seismic catalog. With this aim, several authors have contributed to the study of the historical seismicity of Central America (e.g. Grases, Feldaman; White y Harlow, 1993; White et al. 2004; Ambraseys y Adams, 2001; Peraldo y Montero, 1999), who complied historical data. A first catalogue was developed by Rojas (1993) that comprises the 1522 to 1993 period. This information was integrated in 2007, together with data from the International Seismological Centre (CASC) and the national catalogs of CA countries in a new regional catalogue. Since 2007 a continuous effort has been done in order to complete and update this CA earthquake catalog. In particular, two workshops were held in 2008 and 2011 in the Universidad Politécnica de Madrid (Spain), joining experts from the different CA countries who worked each one in its own catalogue covering the entire region and the border with northwestern Colombia and southern Mexico. These national catalogues were later integrated in a common regional catalogue in SEISAN format. At this aim it was necessary to solve some problems, like to avoid duplicity of events, specially close to the boundaries, to consider the different scales of magnitude adopted by different countries, to take into account the completeness by the different national networks, etc. Some solutions were adopted for obtaining a homogenized catalogue to Mw, containing historical and instrumental events with Mw > 3.5 from 1522 up to 2011. The catalogue updated to December 2007 was the basis for the first regional hazard study carried out by Benito et al., (2011) as part of the collaborative RESIS II project under coordination of NORSAR.

    Satellite data are an important source of information and serve as monitoring crops on large scales. There are several indexes, but the most used for monitoring vegetation is NDVI (Normalized Difference Vegetation Index), calculated from the spectral bands of red (RED) and near infrared (NIR), obtaining the value according to relationship: [(NIR - RED) / (NIR + RED)]. During the years 2010-2013 monthly monitoring was conducted in three areas of Spain (Salamanca, Caceres and Cordoba). Pasture plots were selected and satellite images of two different sensors, DEIMOS-1 and MODIS were obtained. DEIMOS-1 is based on the concept Microsat-100 from Surrey. It is designed for imaging the Earth with a resolution good enough to study terrestrial vegetation cover (20x20 m), although with a wide range of visual field (600 km) to get those images with high temporal resolution. By contrast, MODIS images present a much lower spatial resolution (500x500 m). Indices obtained from both sensors to the same area and date are compared and the results show r2 = 0.56; r2 = 0.65 and r2 = 0.90 for the areas of Salamanca, Cáceres and Cordoba respectively. According to the results obtained show that the NDVI obtained by MODIS is slightly larger than that obtained by the sensor for DEIMOS for same time and area. References J.A. Escribano, C.G.H.

    parts of injured nerves repair, Schwann cells gradually lose regeneration-supporting features and eventually die. Identification of signals that sustain repair cells is therefore an important goal. We have found that in mice the transcription factor STAT3 protects these cells from death and contributes to maintaining the molecular and morphological repair phenotype that promotes axonal regeneration. Defining the molecular mechanisms that maintain repair Schwann cells is an essential step toward developing therapeutic strategies that improve nerve regeneration and functional recovery.

    agriculture soil managed with tillage is hydrophilic, that the use of herbicides trigger a patchy and slight presence of hydrophobicity, that the growth of vegetation reached the highest water repellency degree with a patch distribution of the water repellency, and finally the fire reduced the surface water repellency and changes the spatial pattern. This study aims to fulfil the gap of a sampling strategy that will help the scientist to characterize the soil water repellency with a uniform and standard procedure and protocol. The results show the importance of the management to control the soil repellency (Bodí et al., 2012a) and the importance of the fire and ash and the water repellency (Bodí et al., 2012b; Dlapa et al., 2013; Benito Rueda et al., 2016).

    Full Text Available Córdoba del Tucumán’s forced support of the revolution started in Buenos Aires in May 1810 involved this inland city in a process that would upset their governmental, social and economic development. Working with documents belonging to the Monastery of Santa Catalina, the Archives of the Province of Córdoba and the National Historical Archives, we analyze the behaviour of the Catalinas nuns toward the new authorities arising from the independence movement. The tortuous history of local political alliances in a city that, despite their apparent compliance with the modernist values of the new State, belonged to the Ancient Regime is exposed through the study of a boisterous lawsuit involving the government of the First Triumvirate in 1812 — in which the nuns were accused of being unpatriotic— and a complaint filed by Benito Lazcano, the Episcopal governor, against Hipólito García Pose, trustee of the monastery, between 1815 and 1820. The monastery of Santa Catalina, particularly linked to groups’ leaders of the local society —in large measure contrary to that change— suffered the consequences of the mutation of the regime. The revolutionary governments, in need of economic resources, pressured the cordovan convent for that cede part of their property and transformed, in turn, the internal regime of the religious community. In this way, far from its former prosperity, the monastery of Santa Catalina experienced a continued decline in their revenue and their capacity to recruitment since 1815. On the other hand, the general impoverishment of the population aggravated the situation of the monastery, which 1829 had come to experience regime change towards the «common life», situation which distinguishes it in the context of other monastic experiences in Latin America.La forzada adhesión de Córdoba del Tucumán a la revolución iniciada en Buenos Aires en mayo de 1810, involucró a la ciudad mediterránea en un proceso que

    The hydro-physical opportunities for expanding the beneficial uses of the fixed water supply in the Rio Grande/Bravo Basin to better satisfy an array of water management goals are examined. These include making agriculture more resilient to periodic conditions of drought, improving the reliability of supplies to cities and towns, and restoring lost environmental functions in the river system. This is a comprehensive, outcome-neutral, model- based planning exercise performed by some 20 technical, primarily non-governmental institutions from both countries, aimed at proposing strategies that can reduce future conflicts over water throughout the entire basin. The second track consists in generating a set of future water management scenarios that respond to the needs and objectives of the basin stakeholders in each segment and each country. An array of scenarios for improved water management has been developed for the lower Rio Grande/Rio Bravo basin in Texas and the Mexican state of Tamaulipas. Another set under development will focus on the Rio Conchos and the El Paso/Juarez region. Eventually, scenarios will be generated such that will comprehend the entire basin on both sides of the border. These scenarios are the product of consultations with agricultural water districts, governmental organizations and environmental NGOs. They include strategies for reducing the physical losses of water in the system, conservation transfers, improvements in the operations of the Mexican and international reservoirs, improvements in environmental flow conditions, improvements in reliability of water supplies, and drought coping strategies.These scenarios will be evaluated for hydrologic feasibility by the basin-wide model and the gaming exercises. Modeling is necessary to understand how these options will affect the entire system and how they can be crafted to maximize the benefits and avoid unintended or uncompensated effects. The scenarios that have the potential to provide large

    Some 500 city blocks were selected randomly via population-based stratification. Equal volumes of soil collected from the public space (where present) in front of each house on a block yielded a composite sample. Composites provide neighborhood level "smoothing" relative to sampling many individual houses, and greatly decrease laboratory effort/cost. In the laboratory 10 g of soil were comminuted in a ceramic ball mill, mixed with cellulose/ paraffin binder, and pressed (20 tons) into a pellet. A Panalytical Epsilon5 EDS-XRF, using 8 sequential secondary target conditions and 12 NIST and USGS multi-element rock standards provided analyses. The concentration of Pb ranged from 11 to 420 ppm; Cr, 4.3 - 52 ppm; Cu, 6.5 - 390 ppm; Zn, 17 - 480 ppm; Cd, 0.4 - 12 ppm; and Sb, 2.9 - 20 ppm. High levels of all metals characterize the urban core area of El Paso, which dates to the late 19th Century. This area hosts both commercial and old residential structures, as well as major highways and a large railroad yard. There currently is, and was in the past, considerable light industry in the area. Two highly traveled highway and one railroad border crossing over the Rio Grande into contiguous Cd. Juarez (population close to 2 million) add to current and past contamination. A century-old Pb-Cu-Zn smelter, recently demolished, forms the western boundary of the urban core. Heavy metal pollution from the smelter is recognized near the former site. Its effect on the rest of the urban core is uncertain due to the current and former presence of other heavy metal sources. Aggressive post-World War II growth and expansion of El Paso into the surrounding desert, as is common in the US Southwest, placed newer housing onto more pristine land surfaces. This is reflected in generally low-to-background levels of heavy metals in these newer areas of the city. Thus there is a strong contamination and heavy metals exposure risk gradient between older and newer neighborhoods within a single city

    There has been a growing concern among some United States (US) residents that the increasing number of merchant power plants planned for the Mexican side of the US/Mexican border could contribute to increased air pollution and the misuse of finite water resources in the border region. The case of Border Power Plant Working Group v. DOE, et al. is examined in this paper, providing a focus for a discussion of the border region's future as US merchant power producers continue to position themselves to provide electricity in California. One of the factors in the push to develop power generation on the Mexican side of the border was California's electricity crisis of 2000-2001, and plans have been drawn up to build 22 plants between Mexicali and Ciudad Juarez. A history of the Border Power Plant Working Group (BPPWG) was presented, along with details of the government's granting of permits for the power plants after environmental assessments. By suing the government BPPWG hoped to set a standard for future power plant development in the area. The lawsuit addressed the following 4 primary concerns: air emissions; emission offsets; water cooling; and wastewater discharge. BPPWG aimed to achieve the 3 following results: protective legislation in the 4 U.S. border states that would preclude the use of massive amounts of water in border power plant cooling systems; a critical area designation with pollution limits set low enough to require catalytic control systems; and an overarching annex to the La Paz Agreement that would create a formal bi-national agreement governing the above actions for both countries. A review of environmental law in both countries was presented, along with a description of the proposed plants. A complete review of the lawsuit was provided, along with eventual rulings against the BPPWG. It was concluded that the case showed that power developers had proved that although the plants would contribute to the environmental degradation of the region, the

However, the heterogeneity of responses observed in immuno-oncology (I-O suggests that new approaches may be appropriate to reflect disease dynamics meaningfully. Materials and methods: This study explored the impact of incorporating immune-specific health states into economic models of I-O therapy. Two variants of the PSM and a Markov model were populated with data from one clinical trial in metastatic melanoma patients. Short-term modeled outcomes were benchmarked to the clinical trial data and a lifetime model horizon provided estimates of life years and quality adjusted life years (QALYs. Results: The PSM-based models produced short-term outcomes closely matching the trial outcomes. Adding health states generated increased QALYs while providing a more granular representation of outcomes for decision making. The Markov model gave the greatest level of detail on outcomes but gave short-term results which diverged from those of the trial (overstating year 1 progression-free survival by around 60%. Conclusion: Increased sophistication in the representation of disease dynamics in economic models

    Combustion-derived nanomaterials or ultrafine (fuels. Ultrafine particles (UFPs) can absorb other noxious pollutants including volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), toxic organic compounds, and heavy metals. The combination of high population density, meteorological conditions, and industrial productivity brings high levels of air pollution to the metropolitan area of El Paso, Texas, USA/ Ciudad Juarez, Chihuahua, Mexico, comprising the Paso del Norte air basin. A study conducted by scientists from the Research Triangle Park in North Carolina, analyzed sites adjacent to heavy-traffic highways in El Paso and elucidated higher UFP concentrations in comparison to previously published work exploring pollution and adverse health effects in the basin. UFPs can penetrate deep into the alveolar sacs of the lung, reaching distant alveolar sacs and inducing a series of immune responses that are detrimental to the body: evidence suggests that UFPs can also cross the alveolar-blood barrier and potentially endanger the body's immune response. The physical properties of UFPs and the dynamics of local atmospheric and topographical conditions indicate that emissions of nanosized carbonaceous aerosols could pose significant threats to biological tissues upon inhalation by local residents of the Paso del Norte. This study utilizes Black Carbon (BC) as a model for environmental UFPs and its effects on the immunological response. An in vitro approach is used to measure the ability of BC to promote cell death upon long-term exposure. Human epithelial lung cells (A549), human peripheral-blood monocytes (THP-1), murine macrophages (RAW264.7), and murine epithelial lung cells (LA-4) were treated with BC and assessed for metabolic activity after chronic exposure utilizing three distinct and independent cell viability assays. The cell viability experiments included a chronic study at 7, 10, and 14 days of UFP exposure at six different concentrations of

Methods: Sixty-nine biopsies were collected for immunohistochemical analysis for the presence of IL-6, IL-8, TNF-α, IFN-γ, TGF-β, and IL-10, in 16 fragments from atheromatous plaques, 32 aorta fragments, and 21 valve fragments, using a tissue microarray technique for paraffin embedded tissues. Results: Most patients undergoing revascularization surgery were men >50 years, while those undergoing valve replacement were mostly women <50 years. TNF-α was the most prevalent marker, detected in 91.7% (55/60 of the samples. The mean percent area stained was greater in patients infected with C. pneumoniae (3.81% vs 1.92%; p=0.0115 and specifically in the aorta (4.83% vs 2.25%; p=0.0025; C. trachomatis infection was higher in valves, and C. pneumoniae in plaques, both without statistical significance. There was no significant difference in the cytokine staining profile between patients previously infected with both species and uninfected patients. Conclusion: Although there was no difference in the cytokine profile between patients previously

  12. A multi-dimensional analysis of the upper Rio Grande-San Luis Valley social-ecological system

    Mix, Ken

    The Upper Rio Grande (URG), located in the San Luis Valley (SLV) of southern Colorado, is the primary contributor to streamflow to the Rio Grande Basin, upstream of the confluence of the Rio Conchos at Presidio, TX. The URG-SLV includes a complex irrigation-dependent agricultural social-ecological system (SES), which began development in 1852, and today generates more than 30% of the SLV revenue. The diversions of Rio Grande water for irrigation in the SLV have had a disproportionate impact on the downstream portion of the river. These diversions caused the flow to cease at Ciudad Juarez, Mexico in the late 1880s, creating international conflict. Similarly, low flows in New Mexico and Texas led to interstate conflict. Understanding changes in the URG-SLV that led to this event and the interactions among various drivers of change in the URG-SLV is a difficult task. One reason is that complex social-ecological systems are adaptive, contain feedbacks, emergent properties, cross-scale linkages, large-scale dynamics and non-linearities. Further, most analyses of SES to date have been qualitative, utilizing conceptual models to understand driver interactions. This study utilizes both qualitative and quantitative techniques to develop an innovative approach for analyzing driver interactions in the URG-SLV. Five drivers were identified for the URG-SLV social-ecological system: water (streamflow), water rights, climate, agriculture, and internal and external water policy. The drivers contained several longitudes (data aspect) relevant to the system, except water policy, for which only discreet events were present. Change point and statistical analyses were applied to the longitudes to identify quantifiable changes, to allow detection of cross-scale linkages between drivers, and presence of feedback cycles. Agricultural was identified as the driver signal. Change points for agricultural expansion defined four distinct periods: 1852--1923, 1924--1948, 1949--1978 and 1979

METHODS This is a descriptive study conducted with data of the passive surveillance system of AEFV that is available in the electronic immunization registry (EIR of the computerized medical record of the municipal health service (Juarez System. The study variables were: age, gender, vaccine, dose, clinical manifestations and hospitalization. We estimated rates using AEFV as numerator and administered doses of vaccines as denominator. The surveillance sensitivity was estimated by applying the method proposed by the Centers for Disease Control and Prevention. We used Prais-Winsten regression with a significance level of 5.0%. RESULTS The average annual rate of AEFV was 11.3/10,000 administered doses, however without a trend in the study period (p=0.491. Most cases occurred after the first dose (41.7% and among children under one year of age (72.6%. Vaccines with pertussis component, yellow fever and measles-mumps-rubella were the most reactogenic. We highlighted the rates of hypotonic-hyporesponsive episodes and convulsion that were 4.1/10,000 and 1.5/10,000 doses of vaccines with pertussis component, respectively, most frequently in the first dose; 60,0% of cases presented symptoms in the first 24 hours after vaccination, however, 18.6% showed after 96 hours. The sensitivity of surveillance was 71.9% and 78.9% for hypotonic-hyporesponsive episodes and convulsion, respectively. CONCLUSIONS The EIR-based AEFV surveillance system proved to be useful and highly sensitive to describe the safety profile of vaccines in a medium-sized city. It was also shown that the significant increase of the vaccines included in the basic vaccination schedule in childhood in the last decade did not alter the high safety standard of the National Immunization Program.

  15. Non-Dipole Features of the Geomagnetic Field May Persist for Millions of Years

    Biasi, J.; Kirschvink, J. L.

    2017-12-01

    Here we present paleointensity results from within the South Atlantic Anomaly (SAA), which is a large non-dipole feature of the geomagnetic field. Within the area of the SAA, anomalous declinations, inclinations, and intensities are observed. Our results suggest that the SAA has been present for at least 5 Ma. This is orders-of-magnitude greater than any previous estimate, and suggests that some non-dipole features do not `average out' over geologic time, which is a fundamental assumption in all paleodirectional studies. The SAA has been steadily growing in size since the first magnetic measurements were made in the South Atlantic, and it is widely believed to have appeared 400 years ago. Recent studies from South Africa (Tarduno et al. (2015)) and Tristan da Cunha (Shah et al. (2016)) have suggested that the SAA has persisted for 1 ka and 96 ka respectively. We conducted paleointensity (PI) experiments on basaltic lavas from James Ross Island, on the Antarctic Peninsula. This large shield volcano has been erupting regularly over the last 6+ Ma (dated via Ar/Ar geochronology), and therefore contains the most complete volcanostratigraphic record in the south Atlantic. Our PI experiments used the Thellier-Thellier method, the IZZI protocol, and the same selection criteria as the Lawrence et al. (2009) study of Ross Island lavas (near McMurdo Station), which is the only comparable PI study on the Antarctic continent. We determined an average paleointensity at JRI of 13.8±5.2 μT, which is far lower than what we would expect from a dipole field (55 μT). In addition, this is far lower than the current value over James Ross Island of 36 μT. These results support the following conclusions: The time-averaged field model of Juarez et al. (1998) and Tauxe et al. (2013) is strongly favored by our PI data. The SAA has persisted over James Ross Island for at least 5 Ma, and has not drifted significantly over that time.

    The high-resolution ultrasound has taken to discover small ovary cysts in postmenopausal asymptomatic women who in another situation would not been detected; these cysts frequently disappear spontaneously and rarely develop cancer; however, they are treated aggressively. To know the prevalence, evolution and treatment of ovary simple cysts in the postmenopausal women in our department, since in our country there are not studies that had analyzed these data. We made a retrospective and descriptive study in the Service of Biology of the Human Reproduction of the Hospital Juarez de Mexico, in a four-year period (2000-2003) that included 1,010 postmenopausal women. The statistical analysis was made using the SPSS software program with which we obtained descriptive measurements in localization, dispersion and by a graphic analysis. We found a simple cysts prevalence of 8.2% (n = 83); the average of age at the diagnosis time was 50.76 years with a standard deviation of 5.55; the cysts diameter was between 0.614 to 12,883 cm with a mean and standard deviation of 2.542 and 1.91 cm respectively; in 27.71% of the cases (n = 23), the cysts disappear spontaneously in the follow up of 3 to 36 month (mean of 14.1). Surgery was indicated in 16.46% (n = 13), by increase in the size of the cyst in 9 patients (11.64%) and by changes in morphology from simple to complex in 4 (4.82%). Tumor like markers were made only to 37 patients (44.57%), which were in normal ranks; no carcinoma was found in this group. The prevalence of ovary simple cysts was similar to the reported in literature. Risk of cancer of these cysts is extremely low when a suitable evaluation is made, a reason why the conservative treatment is suggested when these are simple cysts lesser than 5cm with Ca-125 levels within normal ranks. We recommend a follow up every 3-6 months by Doppler color ultrasound and tumor like markers for five years.

    The Mexican Geological Survey (SGM), the National Institute of Statistics, Geography and Informatics (INEGI) and the Autonomous University of San Luis Potosi (UASLP) have established a multidisciplinary team with the objective of creating a national program of geochemical mapping of soils in Mexico. This is being done as part of the North American Soil Geochemical Landscapes Project in partnership with the US Geological Survey and the Geological Survey of Canada. As the first step, a pilot study was conducted over a transect that extends from the Mexico–US border near Ciudad Juarez in the north to the Pacific Ocean in the south. This pilot transect was conducted in two phases, and this paper presents results from the first phase, which sampled soils at about a 40-km spacing along a 730-km transect beginning in Central Mexico and ending at the Pacific Coast. Samples were collected from the A and C horizons at each site and 60 elements were analyzed. This pilot study demonstrates that geochemical mapping based on a 40-km spacing is adequate to identify broad-scale geochemical patterns. Geologic influence (i.e., soil parent material) was the most important factor influencing the distribution of elements along the transect, followed by the influence of regional mineralization. The study also showed that influence by human activities over the transect is minimal except possibly in large mining districts. A comparison of element abundance in the A horizon with the environmental soil guidelines in Mexico showed that the natural concentrations of the studied soils were lower than the established threshold for soil restoration with the exception of V and As. The former had a median value (75 mg/kg) approximately equal to the value established in Mexico for soil restoration in agricultural and residential lands (78 mg/kg), and the latter had three values higher than the 22 mg/kg threshold for soil restoration in agricultural and residential lands. These cases demonstrate

    En el mes de abril de 1519, Hernán Cortés a la cabeza de un grupo de 553 hombres, desembarcó de sus once pequeños navíos, el más grande de los cuales desplazaba apenas cien toneladas, en la costa del golfo de México a la altura de lo que hoy se conoce como la isla de Cozumel, frente a la península de Yucatán. Cuatro meses más tarde, después de haber recorrido la costa occidental del Caribe mexicano, Cortés dio comienzo a una de las aventuras más increíbles del siglo XVI, que habría de terminar dos años más tarde con la derrota del imperio azteca y la destrucción de su capital, Tenochtitlán, por aquel entonces la ciudad más populosa de toda mesoamérica. Antes de iniciar el16 de agosto de 1519 su expedición al interior del territorio mexicano, Cortés quemó los cascos de diez de sus naves, dejando solamente una en reserva que le podría permitir ponerse en contacto con Cuba, Santo Domingo y eventualmente España, si fuere necesario.

    Tuvo sin embargo el cuidado, al desmantelar las embarcaciones, de ocultar los velámenes, las anclas, los clavos y demás elementos de hierro que posteriormente habrían de servirle en la construcción de los bergantines de guerra que en el lago de Texcoco le permitieron el asedio final a Tenochtitlán. Tenochtitlán, la capital del imperio azteca había sido fundada en 1315 por tribus nómadas venidas del norte, de la región de Aztlán o “país de las garzas”, que se asentaron en las regiones lacustres del altiplano central de México, cuando después de un largo peregrinar encontraron como signo promisorio a un águila, que parada en una planta de nopal devoraba una serpiente.

Andrews (34) reports the existence of a curious circular building located at Puerto Rico, Campeche, near Xpujil. His crosssectional view of the tower bears a close resemblance to Ruppert's sketch (6, figure 293) of a horizontal section taken through the windows remaining at the top of the Caracol. Hartung (12) has suggested a possible astronomical use for the Puerto Rico tower, but no analysis of the orientation of its "windows," which are much smaller than those of the Caracol, has yet been conducted. Other circular buildings are reported at Ake (20, p. 113) and Isla Cozumel (35, p. 557). We hope that future investigations of the remains of Yucatecan towers will shed further light upon the significance and use of the Caracol as an astronomical observatory.

The metabolic quotient (qCO2, the relationship between ARM and CBM, the enzymatic activities/COT ratio, and the CBM/ COT ratio were also calculated. For each experimental site, cropped plots presented lower values than undisturbed soil in most of the parameters analyzed (p <0.05. The soil cultivation caused large reductions in COT and COfg. The soybean monoculture, at the experimental site Oliveros, had lower Pasa and qCO2 with respect to corn- soybean-wheat/soybean crop rotation, although the MBC was higher (p <0.05. In Marcos Juarez site, the combined tillage treatment had lower CBM, Pasa, Dasa and Uasa, with respect no-tillage with cover crop (p <0.05. At the Rafaela experimental site, no differences were found in enzymatic activities, although the CBM showed differences between crop rotations. Significant differences were found in qCO2 at the cropped plots with respect to undisturbed soil at the Marcos Juárez experimental site. The higher values of qCO2 in cropped plots are indicative of higher maintenance energy of microorganisms. The Pasa/COT ratio in Marcos Juarez and the relationship between Pasa/COT and Uasa/COT in Rafaela, were lower in T than in cropped plots. One plausible explanation is that in cropped soils, organic carbon decreases at a faster rate than the reduction in enzyme activity, and thus the enzyme activity/COT is higher in cropped than in undisturbed soils. Alternatively, extracellular enzymes could bind to humified organic matter to form humoenzymatic complexes. Soil enzymes were positively correlated with COT and COfg. The assessment of biochemical parameters by means of MBC, qCO2 and enzyme activity of soils under different managements enables short-term changes in soil quality to be monitored. The evaluated soil parameters are shown in some situations be sensitive to anthropogenic disturbance and are well

    Ralph Robert Robbins, Jr., died on 2 December 2005, in Kyle, Texas. His wife, Maria Elena Robbins, his daughters Julia Robbins Kelso and Stephanie Juarez Balles, his son Matthew Juarez, and five grandchildren survive him. Bob was on the faculty at the University of Texas from 1968 until his retirement in 2003. Bob was born in Wichita, Kansas, on 2 September 1938, the only son of Mildred and Ralph Robert Robbins, Sr. Guided by his high school's policy to provide a practical education to children of working-class parents, Bob began high school with a heavy dose of vocational courses until the results of a test indicated his special talent in mathematics. He was awarded a full scholarship to Yale University, graduating magna cum laude in mathematics in 1960. He won the Warner Prize in Mathematics at Yale that year. He received his Ph.D. in 1966 with a dissertation entitled "The Triplet Spectrum of Neutral Helium in Expanding Nebulae" from the University of California at Berkeley. His interest in college teaching was ignited at this time through summer teaching positions at San Mateo California Junior College and the Ohio State University. Following a year at Texas as a McDonald Observatory Post-doctoral Fellow, Bob taught for a year in the physics department of the University of Houston before returning to the University of Texas at Austin as an Assistant Professor of Astronomy in 1968. He was promoted to Associate Professor in 1972. Bob's research in the early 1970s on theoretical studies of helium was of vital importance to astronomers for over three decades. These pioneering calculations became vital to observational astronomers in the mid-1990s as interest grew in the primordial helium produced by the Big Bang. Bob's interest and influence in education was international in scope. In the summers 1968-1970, he was a government consultant in Mathematics in East Pakistan (now Bangladesh). He consulted with the government that was preparing a master plan for technical

    Floods are one of the natural hazards with higher incidence in the south-eastern Spain, the driest region in Europe, causing fatalities, damage of infrastructure and economic losses. Flash-floods in semi arid environments are related to intensive rainfall which can last from few hours to days. These floods are violent and destructive because of their high discharges, sediment transport and aggradation processes in the flood plain. Also during historical times floods affected the population in the south-eastern Spain causing sever damage or in some cases the complete destruction of towns. Our studies focus on the flood reconstruction from historical sources of the Almanzora, Aguas and Antas river basins, which have a surface between 260-2600 km2. We have also compiled information from the Andarax river and compared the flood series with the Guadalentín and Segura basins from previous studies (Benito et. al., 2010 y Machado et al., 2011). Flood intensities have been classified in four levels according to the type of damage: 1) ordinary floods that only affect agriculture plots; 2) extraordinary floods which produce some damage to buildings and hydraulic infrastructure; 3) catastrophic floods which caused sever damage, fatalities and partial or complete destruction of towns. A higher damage intensity of +1 magnitude was assigned when the event is recorded from more than one major sub-basin (stretches and tributaries such as Huércal-Overa basin) or catchment (e.g. Antas River). In total 102 incidences of damages and 89 floods were reconstructed in the Almanzora (2.611 km2), Aguas (539 km2), Antas (261 km2) and Andarax (2.100 km2) catchments. The Almanzora River was affected by 36 floods (1550-2012). The highest events for the Almanzora River were in 1580, 1879, 1973 and 2012 producing many fatalities and destruction of several towns. In addition, we identified four flood-clusters 1750-1780, 1870-1900, 1960-1977 and 1989-2012 which coincides with the periods of

    Groundwater quality in the approximately 653-square-mile South Coast Interior Basins (SCI) study unit was investigated from August to December 2008, as part of the Priority Basins Project of the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The GAMA Priority Basins Project was developed in response to Legislative mandates (Supplemental Report of the 1999 Budget Act 1999-00 Fiscal Year; and, the Groundwater-Quality Monitoring Act of 2001 [Sections 10780-10782.3 of the California Water Code, Assembly Bill 599]) to assess and monitor the quality of groundwater used as public supply for municipalities in California, and is being conducted by the U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board (SWRCB). SCI was the 27th study unit to be sampled as part of the GAMA Priority Basins Project. This study was designed to provide a spatially unbiased assessment of the quality of untreated groundwater used for public water supplies within SCI, and to facilitate statistically consistent comparisons of groundwater quality throughout California. Samples were collected from 54 wells within the three study areas [Livermore, Gilroy, and Cuyama] of SCI in Alameda, Santa Clara, San Benito, Santa Barbara, Ventura, and Kern Counties. Thirty-five of the wells were selected using a spatially distributed, randomized grid-based method to provide statistical representation of the study unit (grid wells), and 19 were selected to aid in evaluation of specific water-quality issues (understanding wells). The groundwater samples were analyzed for organic constituents [volatile organic compounds (VOCs), pesticides and pesticide degradates, polar pesticides and metabolites, and pharmaceutical compounds], constituents of special interest [perchlorate and N-nitrosodimethylamine (NDMA)], naturally occurring inorganic constituents [trace elements, nutrients, major and minor ions, silica, total dissolved solids (TDS), and alkalinity

    Full Text Available Introducción: El objetivo de la etnografía en educación es hacer una descripción minuciosa de los sucesos del aula; de su cotidianidad. Para con ello retratar las visiones del mundo de los participantes y de ahí obtener las estructuras de significado que como grupo construyen para explicarse su mundo. En el caso de la arquitectura se parte de la idea de que el entorno que nos envuelve puede imaginarse como un sistema de información en el que, el medio urbano, la forma física de la arquitectura y la ciudad podrían interpretarse como la traducción de imaginarios hondamente enraizados en la psique de quienes habitan esos espacios. De suerte que el acto individual y colectivo de construirse para sí mismo un ambiente revela la serie de estructuras de pensamiento que regula las relaciones entre las personas y la estructura física de su hábitat. Método: Dada la naturaleza de nuestro estudio ésta se basa en la investigación cualitativa del entorno, partiendo de técnicas etnográficas como lo son la entrevista a profundidad y el análisis de mapas mentales basados en los estudios realizados por el Dr. Benito Narváez Tijerina quien explora las dimensiones del dibujo espontáneo con el que los habitantes describen la ciudad, estableciendo las relaciones de esa clase de representaciones con los rasgos edificados del paisaje para evidenciar las relaciones entre la morfogénesis de la ciudad imaginaria y la ciudad real. Resultados: Las dimensiones perceptivas e imaginarias se superponen mas no son excluyentes de la dimensión material-arquitectónica de la urbe. La ciudad no es capturada solamente por los sentidos, sino que se interioriza e identifica con nuestro propio cuerpo y con nuestra experiencia existencial; el habitante de la ciudad a través de un proceso cognitivo, recoge la información necesaria aportada por los sentidos y proyecta sus propias imágenes mentales sobre la ciudad.

    The construction of the Cistercian Monastery began at 1180, in an initial Late Romanesque style in which the Church was erected; later on, in 1258, the church underwent a severe fire, only the apse stood standing. The church was reconstructed at the end of the 13th century in Mudejar style. Gothic style was used later on, in the 16th century, for the reconstruction of the funerary chapel, and Renaissance style for the Plateresque door in between the church and the sacristy. At the end of the 16th century, the main door to access the church was built in Baroque style. In 1836, the Ecclesiastical Confiscations resulted on transfer the Monastery into particular owners. This fact favoured its abandon and ruin state until 1979, when architect Mariano Garcia Benito purchased the property and started the conservation and consolidation of the complex, beginning with the Bell Tower. Natural stone materials used in the Monastery are igneous (granite) and metamorphic rocks (gneiss and schist), and artificial stone materials are bricks and mortars, both joint and rendering ones. Granite is the most abundant material used in the complex, with a structural/reinforcing role in elements such as lintels, jambs, buttresses, or bottom areas of the walls with greater sizes and better dimensioned. Some pillars are granite built, from the large ashlars of the sacristy, to the rubble-work of the Mozarab chapel. Two types of monzogranite can be differentiated in relation to distinct constructive stages: the coarse texture monzogranite is used in the first building stages, while the fine texture monzogranite was employed mainly from 17th century on. Petrophysical characteristics of these granites are different but show a good quality to be used in construction. Nevertheless, the abandon and partial ruin of the complex, the devastating fire events (the second one in 1743) leaded to the decay acceleration of the monumental complex, being nowadays the church in ruin, with no roofs and walls

This clinic is an extension of that run by the Sisters of Saint Benedict in Lechnerstrasse, Munich. It consists of two blocks, of 4 and 5 floor levels. It has a semibasement, housing the services, and some spare rooms and other facilities, described in the enclosed plans. The ground floor provides room for 25 beds, for the older boys. On the second floor there are 30 beds for those recently born, whilst the third floor has space for 30 beds for prematurely born babies. The nurses live in the attic, where there are 15 bedrooms, each with two beds, a kitchen and suitable auxiliary facilities. Much thought has been given to the design of details, the general distribution and circulation system has been planned with much care, and the overall functional efficiency of the building as a children's clinic has been kept a paramount factor. All this makes this building an outstanding one among those of this type.Los objetivos principales perseguidos aquí son: conseguir una eficaz vigilancia y protección de los niños; organizar los puestos de trabajo de las enfermeras para que resulten prácticos y agradables, y crear un ambiente familiar La clínica construida —como ampliación de las instalaciones que las Hermanas de San Benito poseen en la calle Lachner, en Munich— comprende dos cuerpos de edificio unidos, de 4 y 5 plantas de altura, respectivamente, y está distribuida del siguiente modo: el semisótano aloja, además de la zona de servicios, una serie de dependencias, que vienen descritas en la respectiva documentación gráfica.

Las grandes áreas metropolitanas de América Latina han atestiguado el incremento de la violencia urbana y la Zona Metropolitana de la Ciudad de México (ZMCM no es la excepción. Uno de los delitos con el mayor número de averiguaciones previas en la ZMCM es el robo de vehículos con un promedio de 40 336 durante el periodo 1995-2007. En 2010 el robo de vehículos alcanzó las 44 446 averiguaciones previas, representando el 38% del total de las averiguaciones previas registradas en la entidad. Sin embargo, este delito no muestra una distribución homogénea en todo el territorio sino que muestra una alta concentración en algunas delegaciones de la Ciudad de México como Benito Juárez, Coyoacán y Cuauhtémoc. En este contexto nos preguntamos ¿Existe relación espacial entre la concentración de los robos de vehículos y las características socioeconómicas del entorno? El soporte teórico del artículo lo proporcionan teorías como la desorganización social y las actividades rutinarias. La información usada del robo de vehículos corresponde a las denuncias hechas por las personas afectadas y que se convirtieron en averiguaciones previas, la fuente de información es la Procuraduría General de Justicia del Distrito Federal (PGJDF, 2010.

The efforts of  organizations of relatives of disappeared women  to secure the solidarity of national and international organizations and networks have been crucial  in influencing the federal Mexican government to  investigate these crimes. In addition, by placing  the problem inside wider frames of interpretation  – those of gender violence and human rights–, the  organizations of Juarez have helped to open the  debate concerning the question of violence in  general against women in Mexico. Nevertheless,  the results of the movement at the local level are  still far from satisfactory due to questions related  both to internal problems and weaknesses of local  organizations as well as to structural problems of  democracy in Mexico, which include the weakness of rule of law and the ineffectiveness of the  political system in implementing effective accountability.Resumen:El artículo analiza el impacto de la internacionalización de la movilización en pro del esclarecimiento de los crímenes cometidos contra mujeres  en Ciudad Juárez, México.

    1998-09-01

    Merril Eisenbud's series of books on environmental radioactivity have long had a place on the bookshelves of those involved with the environmental aspects of radiation protection. They provide authoritative coverage of the subject including sources, transport mechanisms and effects. The first edition, published in 1963, was naturally mostly concerned with the effects of nuclear weapons testing in the atmosphere. The second edition, published in 1977, reflected the then expansive phase of nuclear power development worldwide and included an extensive treatment of the nuclear fuel cycle and its contributions to environmental radioactivity. In 1987 the third edition included coverage of the Three Mile Island accident and the Chernobyl accident against the background of cessation of new orders for nuclear plant in the United States. The fourth edition is a major revision with a lot of new material, and the welcome adoption of SI units throughout. The principal additions to the new edition are chapters on environmental surveillance, radiological assessment and dose reconstruction, and the remediation of contaminated sites; nothing has been lost from the extensive coverage of other topics in the third edition, whilst the text and bibliography have been revised and brought up to date. Earlier editions of the book have provided good summaries of accidents which have resulted in environmental contamination, and the updating here results in more extensive and up-to-date coverage of the Three Mile Island and Chernobyl accidents, including the more recent evidence of health effects from the latter, together with new sections on the Palomares nuclear weapons accident in Spain, the Mayak/Chelyabinsk complex in Russia, and the accidents involving lost gamma radiation sources in Juarez, Mexico and Goiania, Brazil. Both here and in the extensive coverage of contamination at the USDoE production sites the new edition reflects and benefits from the increased public availability

  15. Evaluation of emission control strategies to reduce ozone pollution in the Paso del Norte region using a photochemical air quality modeling system

    Valenzuela, Victor Hugo

    Air pollution emissions control strategies to reduce ozone precursor pollutants are analyzed by applying a photochemical modeling system. Simulations of air quality conditions during an ozone episode which occurred in June, 2006 are undertaken by increasing or reducing area source emissions in Ciudad Juarez, Chihuahua, Mexico. Two air pollutants are primary drivers in the formation of tropospheric ozone. Oxides of nitrogen (NOx) and volatile organic compounds (VOC) undergo multiple chemical reactions under favorable meteorological conditions to form ozone, which is a secondary pollutant that irritates respiratory systems in sensitive individuals especially the elderly and young children. The U.S. Environmental Protection Agency established National Ambient Air Quality Standards (NAAQS) to limit ambient air pollutants such as ozone by establishing an 8-hour average concentration of 0.075 ppm as the threshold at which a violation of the standard occurs. Ozone forms primarily due reactions in the troposphere of NOx and VOC emissions generated primarily by anthropogenic sources in urban regions. Data from emissions inventories indicate area sources account for ˜15 of NOx and ˜45% of regional VOC emissions. Area sources include gasoline stations, automotive paint bodyshops and nonroad mobile sources. Multiplicity of air pollution emissions sources provides an opportunity to investigate and potentially implement air quality improvement strategies to reduce emissions which contribute to elevated ozone concentrations. A baseline modeling scenario was established using the CAMx photochemical air quality model from which a series of sensitivity analyses for evaluating air quality control strategies were conducted. Modifications to area source emissions were made by varying NOx and / or VOC emissions in the areas of particular interest. Model performance was assessed for each sensitivity analysis. Normalized bias (NB) and normalized error (NE) were used to identify

    -assessment model of distance learning program at the Universidad Juarez Autónoma de Tabasco, Mexico during the period 2008-2009. The model was designed by ANUIES. The findings of this study and the literature review on the subject reflect the need to design local or regional contextualized measuring items. The proposal is mainly based on the literature review, and the expert panel selected through the Delphi and combined TZ method. The methodological strategy consists of four stages: a the review of evaluation models; b selection of experts from two universities in the states of Tabasco and Chiapas, which have more than ten years of experience with distance learning programs; c the self-diagnostic instrument designed for distance learning programs and d the validity of the instrument by those experts. This paper describes three out of four stages of this study. The average rate on self-assessment experts was similar in the two universities. It is concluded that the level of experts share related knowledge, particularly in the design of learning materials or objects, but not in quality indicators estimated for virtual education.

Zaalov This paper deals with the research undertaken during the COST 296 Action in Working Group 2 on Advanced Terrestrial Systems. The Working Group comprised three work packages covering various topics: Radar and Radiolocation, HF/MF Communications, and Spectrum Management. Results from this Working Group are presented in this paper, and may be summarised as follows. Aspects of HF propagation The propagation characteristics of radio signals are important parameters to consider when designing and operating radio systems. From the point of view Working Group 2 of the COST-296 Action, interest lies with effects associated with propagation via the ionosphere of signals within the HF band. Several aspects were covered: The directions of arrival and times of flight of signals received over a path oriented along the trough have been examined and several types of propagation effects identified. Of particular note, combining the HF observations with satellite measurements has identified the presence of irregularities within the floor of the trough that result in propagation displaced from the great circle direction. An understanding of the propagation effects that result in deviations of the signal path from the great circle direction are of particular relevance to the operation of HF radiolocation systems. Inclusion of the results from the above mentioned measurements into a propagation model of the northerly ionosphere (i.e. those regions of the ionosphere located poleward of, and including, the mid-latitude trough) and the use of this model to predict the coverage expected from transmitters where the signals

    analysis is not as simple as in the case of direct methods. Indirect methods offer the possibility to assessment and mapping of geodiversity of large and not easy accessible research areas. The foregoing examples mainly tend to refer to areas at the local or regional scale. These analyses are although possible for the implementation of large spatial units, such as territories of the country or state (Zwoliński 2007, Benito-Calvo et al. 2009, Pereira et al. 2013, 2015). A fundamental difference lies in the appropriate, corresponding to the spatial scale and the specification of the study areas, selection of the assessing criterion, and above all, the input geodata. In the geodiversity assessments, access to the data in the adequate resolution and accuracy is especially important. Acquisition and integration of the geodata often requires considerable financial and temporal outlay and not infrequently could be a serious limitation to perform some analyzes. The proposal of geomorphometry based landform geodiversity indirect assessment method and single, in addition, easy to obtain source data - digital elevation model, might create new opportunities for its broad implementation across numerous disciplines. The research on the assessment of geodiversity must be regarded to be at an initial stage at present. While the conception of geodiversity itself has a reliable theoretical foundation, no universal method of its assessment has been developed yet. It is only the adoption of a generally accepted and clear methodology of geodiversity evaluation that will make it possible to implement it widely in many fields of science, administration and the management of geospace. Then geodiversity can become as important an indicator as biodiversity is today.

    tendremos que apelar dentro de poco tiempo llevados por el constante empobrecimiento de los suelos, el aumento de población y el incremento de demanda de mercados. Estos y otro gran número de factores son los que mueven a la población rural hacia métodos la mayoría de las veces adquiridos por observaciones y deducciones tomadas de su propio cultivo, en los cuales van envueltas muchas fatigas, muchos sudores y trabajos, pero que interpretando bien, es la misma necesidad aguzadora de la inteligencia que ejercita el músculo para luchar por subsistir, que es analógo a progresar. No será este problema regional un asomo al futuro aspecto al cual marchamos con rapidez y que llegará en un no lejano día para el país como resultado de los desmontes, el arrastre de los suelos hacia los ríos y el exceso de población. Algunos puntos serán tratados con mayor intensidad, como son: todo lo relacionado con el cultivo de la cebolla que en realidad fue nuestra mira principal durante el reconocimiento; la erosión del suelo por considerarla como un verdadero problema de la región, y algunos puntos de vista nuestros sobre un programa de acción a este respecto. Aprovechamos la ocasión para agradecer a los señores Carvajalino Jácome, Benito Cabrales, Antonio García y Alberto Franco por las facilidades y atenciones que los tres primeros nos brindaron, sin las cuales no habríamos llenado nuestro deseo de estudiar el problema; y al último, por su valiosa cooperación de los dibujos aquí insertados; también, a los hacendados que tan galantemente contribuyeron con sus datos para el mejor éxito de la comisión.

    emphasize one flood typology or one flood dynamic (for example flash floods are often over-represented than slow dynamic floods in existing databases). Thus, the selected criteria have to introduce a general overview of flooding risk in France by integrating all typologies: storm surges, torrential floods, rising groundwater level and resulting to flood, etc. The methodology developed for the evaluation grid is inspired by several scientific works related to historical hydrology (Bradzil, 2006; Benito et al., 2004) or extreme floods classification (Kundzewics et al. 2013; Garnier E., 2005). The referenced information are mainly issued from investigations realized for the PFRA (archives, local data),from internet databases on flooding disasters, and from a complementary bibliography (some scientists such as Maurice Pardé a geographer who largely documented French floods during the 20th century). The proposed classification relies on three main axes. Each axis is associated to a set of criteria, each one related to a score (from 0.5 to 4 points), and pointing out a final remarkability score. • The flood intensity characterizing the flood's hazard level. It is composed of the submersion duration, important to valorize floods with slow dynamics as flooding from groundwater, the event peak discharge's return period, and the presence of factors increasing significantly the hazard level (dykes breaks, log jam, sediment transport…) • The flood severity focuses on economic damages, social and political repercussions, media coverage of the event, fatalities number or eventual flood warning failures. Analyzing the flood consequences is essential in order to evaluate the vulnerability of society at disaster date. • The spatial extension of the flood, which contributes complementary information to the two first axes. The evaluation grid was tested and applied on the sample of 176 remarkable events. Around twenty events (from 1856 to 2010) come out with a high remarkability rate

    El Paso, Tex., and Ciudad Juarez, Chihuahua, Mexico, and the industries in -that area draw their water supplies from wells, most of which are from 600 to 800 feet deep. In 1906, the estimated average pumpage there was about 1,000,000 gallons a day, and by 1935 it had increased to 15,400,000 gallons a day. The water-bearing beds, consisting of sand and gravel interbedded wire clay, tie in the deep structural trough known as the Hueco bolson, between the Organ and Franklin Mountains on the west, the Hueco, Finlay, and Malone Mountains on the east, the Tularosa Basin on the north, and the mountain ranges of Mexico on the south. From the gorge above El Paso to that beginning near Fort Quitman, about 90 miles southeast .of El Paso, the Rio Grande has eroded a flat-bottomed, steepwalled valley, 6 to 8 miles wide and 225 to 350 feet deep. No other large drainage channels have been developed on the bolson. The valley is known as the El Paso Valley, and the uneroded upland part of the bolson is called the Mesa. In the lowest parts of the El Paso Valley, the water-table is nearly at the surface. The quality of the underground water in the valley varies greatly both vertically and laterally. To a depth of about 400 to 500 feet it is in general too highly mineralized for municipal use, but between about. 500 and 900 feet good water may be obtained from several beds. In the beds between 500 and 900 feet the water level in wells is in places as. much as 20 feet lower than that in the shallow beds. Beneath the Mesa the water level .varies from about 200 feet beneath the surface, where the ground elevation is least, to about 400 feet. where it is highest. The water beneath the Mesa in general is of satisfactory quality and contains less than 500 parts per million of dissolved solids. Two cones of depression in the water table have been formed by the pumping near El Paso--one m the vicinity of the Mesa well field, the other around the Montana well field in the valley. The water

    Full Text Available OBJECTIVE: To investigate the risk effects of poverty and exposure to collective violence attributed to organized crime on the mental health of children living on the United States-Mexico border. METHODS: A repeated, cross-sectional study measured risk effects by comparing scores of psychosocial and behavioral problems among children and adolescents living on the border in the United States or Mexico in 2007 and 2010. Patients living in poverty who responded once to the Pictorial Child Behavior Checklist (P+CBCL in Spanish were randomly selected from clinics in El Paso, Texas, United States (poverty alone group, and Ciudad Juarez, Chihuahua, Mexico (poverty plus violence group. Only children of Hispanic origin (Mexican-American or Mexican living below the poverty level and presenting at the clinic for nonemergency visits with no history of diagnosed mental, neurological, or life-threatening disease or disability were included. RESULTS: Exposure to collective violence and poverty seemed to have an additive effect on children's mental health. Children exposed to both poverty and collective violence had higher problem scores, as measured by the P+CBCL, than those exposed to poverty alone. CONCLUSIONS: It is important to consider that children and adolescents exposed to collective violence and poverty also have fewer chances to receive treatment. Untreated mental health problems predict violence, antisocial behaviors, and delinquency and affect families, communities, and individuals. It is crucial to address the mental health of children on the border to counteract the devastating effects this setting will have in the short term and the near future.OBJETIVO: Investigar los efectos del riesgo de pobreza y la exposición a la violencia colectiva atribuida al crimen organizado sobre la salud mental de los niños que viven en la frontera entre México y los Estados Unidos. MÉTODOS: En este estudio transversal seriado se midieron los efectos del riesgo

    La Sociedad de Medicina y Ciencias Naturales, establecida en la ciudad de Santafé de Bogotá, como ya vimos, el 3 de enero de 1873, tuvo en cambio vida continua e ininterrumpida, habiéndose reunido, durante sus 18 años de existencia como tal con regularidad, siendo gobernada por 15 Juntas Directivas, iniciadas por la presidida por el Dr. Manuel Plata Azuero, con la Vice-presidencia de Andrés María Pardo, la Secretaria de Abraham Aparicio y la Tesorería de Bernardino Medina, entre 1873 y 1874, hasta la última, presidida por el Dr. Juan de Dios Carrasquilla, con la Vice-presidencia de Policarpo Pizarro, la Secretaria de Pablo García Medina y la Tesorería de Gabriel Durán Borda, entre 1890 y 1891...
