    Cambrian and Ordovician shelf, platform, and basin rocks are present in Sonora, Mexico, and southern Arizona and were deposited on the southwestern continental margin of North America (Laurentia). Cambrian and Ordovician rocks in Sonora, Mexico, are mostly exposed in scattered outcrops in the northern half of the state. Their discontinuous nature results from extensive Quaternary and Tertiary surficial cover, from Tertiary and Mesozoic granitic batholiths in western Sonora, and from widespread Tertiary volcanic deposits in the Sierra Madre Occidental in eastern Sonora. Cambrian and Ordovician shelf rocks were deposited as part of the the southern miogeocline on the southwestern continental margin of North America.

    A study to address Ambos (Both) Nogales' air quality concerns was conducted by the Arizona Department of Environmental Quality (ADEQ), in conjunction with Mexico's Secretaria de Medio Ambiente, Recursos Naturales y Pesca (SEMARNAP), from 1994 to 1998. The study, which is part of the US-Mexico Border XXI Program, consisted of the following tasks: (1) air sampling/monitoring; (2) emissions inventory; (3) meteorological modeling; and, (4) health risk assessment. The following types of samples were collected: particulate matter (PM); volatile organic compounds; semi-volatile organic compounds; and aldehydes. All samples were collected for a 24-hour period; every sixth day during the warm months (April--September), and every third day during the cold months (October--March). There were a total of six sampling stations; three on each side of the border. PM samples were collected at all six sites, while samples for Hazardous Air Pollutants (HAPs) were collected at four of those sites. Sample analyses were performed at the Desert Research Institute (DRI) in Reno, Nevada. Furthermore, four of the sites were outfitted with meteorological equipment, in order to gather data on wind speed and direction. PM and meteorological data are still being collected at two sampling sites, one in Arizona and one in Sonora. An emissions inventory of point, mobile and area sources for the Ambos Nogales area (12 x 19 km. domain), was developed following completion of the sampling effort. In order to accomplish this task, ADEQ contracted the services of RADIAN International and Powers Engineering; which in turn enlisted the services of Heuristica Ambiental of Hermosillo, Sonora. This task was completed in July, 1997. Vehicular emissions were found to be one of the main contributors of air emissions in the Ambos Nogales area. The third task of this project consisted developing meteorological models of the study area.

    Full Text Available Este artículo se centra en el periodo 1990-2000, una década de intensificada integración económica en la región Sonora-Arizona. En parte, este proceso representa un resultado anticipado de la implementación del TLCAN y, por otro lado, el efecto de la yuxtaposición con otras tendencias regionales y globales. En particular, esta década manifiesta un tiempo de intensificación de la integración económica, por medio de la cooperación transfronteriza para el desarrollo económico entre gobiernos y asociaciones público-privadas apoyadas por éstos. Entre los objetivos centrales del Plan Estratégico Binacional de Desarrollo Económico de la Región Sonora-Arizona estaban fortalecer la competitividad regional en los mercados del TLCAN y global, atraer más inversión y, a través del incremento en las exportaciones, mejorar el crecimiento económico general y elevar el ingreso. Los resultados del análisis realizado sugieren un creciente papel de las exportaciones en la economía de la región. Sin embargo, quienes toman las decisiones enfrentan dos preocupaciones fundamentales. Primero, indicadores seleccionados de la participación en los mercados sugieren que la región está perdiendo posición relativa dentro del área del TLCAN. Segundo, parece ser que los beneficios de la creciente integración económica y la consecuente expansión del comercio no se han aprovechado cabalmente y, hasta ahora, no se han manifestado en indicadores promedio de bienestar. Estos eventos demandan una reevaluación urgente de las estrategias económicas regionales.

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

  7. Hydrogeologic Framework of the Upper Santa Cruz Basin (Arizona and Sonora) using Well Logs, Geologic Mapping, Gravity, Magnetics, and Electromagnetics

    In 2006, the U.S. Congress passed the U.S.-Mexico Transboundary Aquifer Assessment Act which provides a framework for study of aquifers shared by the United States and Mexico. The aquifer of the Upper Santa Cruz Basin was chosen as one of four priority aquifers for several reasons, including water scarcity, a population greater than 300,000, groundwater as the sole source of water for human use, and a riparian corridor that is of regional significance for migratory birds and other animals. Several new mines are also being proposed for this area which may affect water quality and availability. To date, a number of studies have been carried out by a binational team composed of the U.S. Geological Survey, the Mexican National Water Commission, and the Universities of Arizona and Sonora. Construction of a cross-border hydrogeologic framework model of the basin between Amado, Arizona and its southern boundary in Sonora is currently a high priority. The relatively narrow Santa Cruz valley is a structural basin that did not experience the same degree of late Cenozoic lateral extension and consequent deepening as found in other basin-and-range alluvial basins, such as the Tucson basin, where basin depth exceeds 3000 meters. This implies that storage may be much less than that found in other basin-and-range aquifers. To investigate the geometry of the basin and facies changes within the alluvium, a database of over one thousand well logs has been developed, geologic mapping and transient electromagnetic (TEM) surveys have been carried out, and information from previous electromagnetic, magnetic, and gravity studies is being incorporated into the hydrogeologic framework. Initial geophysical surveys and analyses have focused on the portion of the basin west of Nogales, Arizona, because it supplies approximately 50% of that city's water. Previous gravity and magnetic modeling indicate that this area is a narrow, fault-controlled half graben. Preliminary modeling of airborne

    We studied the reproductive ecology of female Sonora mud turtles (Kinosternon sonoriense) at Montezuma Well, a chemically-challenging natural wetland in central Arizona, USA. Females matured between 115.5 and 125 mm carapace length (CL) and 36-54% produced eggs each year. Eggs were detected in X-radiographs from 23 April-28 September (2007-2008) and the highest proportion (56%) of adult females with eggs occurred in June and July. Clutch frequency was rarely more than once per year. Clutch size was weakly correlated with body size, ranged from 1-8 (mean = 4.96) and did not differ significantly between years. X-ray egg width ranged from 17.8-21.7 mm (mean 19.4 mm) and varied more among clutches than within. Mean X-ray egg width of a clutch did not vary significantly with CL of females, although X-ray pelvic aperture width increased with CL. We observed no evidence of a morphological constraint on egg width. In addition, greater variation in clutch size, relative to egg width, suggests that egg size is optimized in this hydrologically stable but chemically-challenging habitat. We suggest that the diversity of architectures exhibited by the turtle pelvis, and their associated lack of correspondence to taxonomic or behavioral groupings, explains some of the variation observed in egg size of turtles.

    The United States - Mexico border area faces the challenge of integrating aspects of its binational physical boundaries to form a unified or, at least, compatible natural resource management plan. Specified geospatial components such as stream drainages, mineral occurrences, vegetation, wildlife, and land-use can be analyzed in terms of their overlapping impacts upon one another. Watersheds have been utilized as a basic unit in resource analysis because they contain components that are interrelated and can be viewed as a single interactive ecological system. In developing and analyzing critical regional natural resource databases, the Environmental Protection Agency (EPA) and other federal and non-governmental agencies have adopted a ?watershed by watershed? approach to dealing with such complicated issues as ecosystem health, natural resource use, urban growth, and pollutant transport within hydrologic systems. These watersheds can facilitate the delineation of both large scale and locally important hydrologic systems and urban management parameters necessary for sustainable, diversified land-use. The twin border cities area of Nogales, Sonora and Nogales, Arizona, provide the ideal setting to demonstrate the utility and application of a complete, cross-border, geographic information systems (GIS) based, watershed analysis in the characterization of a wide range of natural resource as well as urban features and their interactions. In addition to the delineation of a unified, cross-border watershed, the database contains sewer/water line locations and status, well locations, geology, hydrology, topography, soils, geomorphology, and vegetation data, as well as remotely sensed imagery. This report is preliminary and part of an ongoing project to develop a GIS database that will be widely accessible to the general public, researchers, and the local land management community with a broad range of application and utility.

    The National Optical Astronomy Observatory, in collaboration with Science Foundation Arizona and the Arizona public schools, has initiated a program of optics education that has been implemented in the Arizona cities of Flagstaff, Yuma, and Safford. A program is planned for Globe, Arizona and several other locations. The program is aimed at 5th grade teachers and students. It relies on NOAO-developed optics teaching kits designed around the Galileoscope student telescope kits. The program is designed to reach every 5th grade teacher and every 5th grade student in each city. Professional development is provided for the teachers using the NOAO-developed "Teaching with Telescopes" optics teaching kits which are given to each teacher. Each 5th grade student is part of a team building a Galileoscope and receives additional training on how to use the Galileoscope during the day or night. At the end of the training period a large star party is held for all of the students, their families, and their friends. The program is evaluated through the University of Arizona. This model has been successfully implemented during the past two years and we are exploring national replication. This program provides a cost-effective way to inject optics into the schools in an attractive, citywide program model. The talk will discuss the model in detail and some of the mistakes we have made as we have tested the model.

    Arizona but have been introduced in several areas in the southern and central part of the State, including Montezuma Well (the Well). The only native turtle at the Well is the Sonora mud turtle (Kinosternon sonoriense). Interactions between sliders and mud turtles have not been investigated at the Well or elsewhere. However, basking sites preferred by aquatic turtles are rare at the Well, suggesting one potential avenue for resource competition between sliders and Sonora mud turtles. In this study, we collected data on both species to evaluate the possible effects of slider turtles on Sonora mud turtles at Montezuma Well. During live trapping in the spring, summer, and early fall of 2007 and 2008, we removed slider turtles that we captured in the Well. We also collected ecological data on the mud turtles captured in the trapping effort. Separate behavioral observations of the turtles in the Well provided additional information on the ecology of the two species in the unusual environment of the Well, and also of interactions between the sliders and mud turtles. In this report, we describe the results of 2 yr of study of the turtles of Montezuma Well. We incorporate older data on the mud turtles in the Well to assess long-term population trends and potential response to the introduced slider turtles. We also report on aspects of basic ecology for the poorly understood Sonora mud turtle. The National Park Service requested that we incorporate public outreach as part of this research effort, so we also describe the outreach efforts associated with the turtle study.

    The U.S. Department of Housing and Urban Development (HUD) and the U.S. Geological Survey (USGS) have developed a joint project to create Internet-enabled geographic information systems (GIS) that will help cities along the United States-Mexico border deal with issues related to colonias. HUD defines colonias as rural neighborhoods in the United States-Mexico border region that lack adequate infrastructure or housing and other basic services. They typically have high poverty rates that make it difficult for residents to pay for roads, sanitary water and sewer systems, decent housing, street lighting, and other services through assessment. Many Federal agencies recognize colonias designations and provide funding assistance. It is the intention of this project to empower Arizona-Sonora borderland neighborhoods and community members by recognizing them as colonias. This recognition will result in eligibility for available economic subsidies and accessibility to geospatial tools and information for urban planning. The steps to achieve this goal include delineation of colonia-like neighborhoods, identification of their urbanization over time, development of geospatial databases describing their infrastructure, and establishment of a framework for distributing Web-based GIS decision support systems. A combination of imagery and infrastructure information was used to help delineate colonia boundaries. A land-use change analysis, focused on urbanization in the cities over a 30-year timeframe, was implemented. The results of this project are being served over the Internet, providing data to the public as well as to participating agencies. One of the initial study areas for this project was the City of Douglas, Ariz., and its Mexican sister-city Agua Prieta, Sonora, which are described herein. Because of its location on the border, this twin-cities area is especially well suited to international manufacturing and commerce, which has, in turn, led to an uncontrolled spread of

    2015-09-01

    Full Text Available Government-led pollution prevention programs tend to focus on large businesses due to their potential to pollute larger quantities, therefore leaving a gap in programs targeting small and home-based businesses. In light of this gap, we set out to determine if a voluntary, peer education approach led by female, Hispanic community health workers (promotoras can influence small and home-based businesses to implement pollution prevention strategies on-site. This paper describes a partnership between promotoras from a non-profit organization and researchers from a university working together to reach these businesses in a predominately Hispanic area of Tucson, Arizona. From 2008 to 2011, the promotora-led pollution prevention program reached a total of 640 small and home-based businesses. Program activities include technical trainings for promotoras and businesses, generation of culturally and language appropriate educational materials, and face-to-face peer education via multiple on-site visits. To determine the overall effectiveness of the program, surveys were used to measure best practices implemented on-site, perceptions towards pollution prevention, and overall satisfaction with the industry-specific trainings. This paper demonstrates that promotoras can promote the implementation of pollution prevention best practices by Hispanic small and home-based businesses considered “hard-to-reach” by government-led programs.

    The Brain and Body Donation Program (BBDP) at Banner Sun Health Research Institute (http://www.brainandbodydonationprogram.org) started in 1987 with brain-only donations and currently has banked more than 1600 brains. More than 430 whole-body donations have been received since this service was commenced in 2005. The collective academic output of the BBDP is now described as the Arizona Study of Aging and Neurodegenerative Disorders (AZSAND). Most BBDP subjects are enrolled as cognitively normal volunteers residing in the retirement communities of metropolitan Phoenix, Arizona. Specific recruitment efforts are also directed at subjects with Alzheimer's disease, Parkinson's disease and cancer. The median age at death is 82. Subjects receive standardized general medical, neurological, neuropsychological and movement disorders assessments during life and more than 90% receive full pathological examinations by medically licensed pathologists after death. The Program has been funded through a combination of internal, federal and state of Arizona grants as well as user fees and pharmaceutical industry collaborations. Subsets of the Program are utilized by the US National Institute on Aging Arizona Alzheimer's Disease Core Center and the US National Institute of Neurological Disorders and Stroke National Brain and Tissue Resource for Parkinson's Disease and Related Disorders. Substantial funding has also been received from the Michael J. Fox Foundation for Parkinson's Research. The Program has made rapid autopsy a priority, with a 3.0-hour median post-mortem interval for the entire collection. The median RNA Integrity Number (RIN) for frozen brain and body tissue is 8.9 and 7.4, respectively. More than 2500 tissue requests have been served and currently about 200 are served annually. These requests have been made by more than 400 investigators located in 32 US states and 15 countries. Tissue from the BBDP has contributed to more than 350 publications and more than 200

    Rocky Mountain spotted fever (RMSF), a life-threatening tickborne zoonosis caused by Rickettsia rickettsii, is a reemerging disease in Mexico (1,2). R. rickettsii is an intracellular bacterium that infects vascular endothelium and can cause multisystem organ failure and death in the absence of timely administration of a tetracycline-class antibiotic, typically doxycycline. Epidemic RMSF, as described in parts of Arizona and Mexico, is associated with massive local infestations of the brown dog tick (Rhiphicephalus sanguineus sensu lato) on domestic dogs and in peridomestic settings that result in high rates of human exposure; for example, during 2003-2012, in Arizona the incidence of RMSF in the three most highly affected communities was 150 times the U.S. national average (3,4). In 2015, the Mexico Ministry of Health (MOH) declared an epidemiologic emergency because of high and sustained rates of RMSF in several states in northern Mexico, including the state of Sonora. During 2004-2015, a total of 1,129 cases and 188 RMSF deaths were reported from Sonora (Sonora MOH, unpublished data, 2016). During 2009-2015, one impoverished community (community A) in Sonora reported 56 cases of RMSF involving children and adolescents, with a case-fatality rate of 40% (Sonora MOH, unpublished data, 2016). Poverty and lack of timely access to health services are risk factors for severe RMSF. Children are especially vulnerable to infection, because they might have increased contact with dogs and spend more time playing around spaces where ticks survive (5). In Sonora, case fatality rates for children aged <10 years can be as high as 30%, which is almost four times the aggregate case-fatality rate reported for the general population of the state (8%) (2), and 10-13 times higher than the case-fatality rate described for this age group in the United States (2.4%) (6).

    Programmed cell death (PCD) in insect metamorphosis assumes a great diversity of morphology and controlling processes that are still not well understood. With the objective of obtaining information about the PCD process, salivary glands of Drosophila arizonae and D. mulleri were studied during larval-pupal development. From the results, it can be concluded that the type of the PCD that occurs in these organs is morphologically typical of apoptosis (formation of apoptotic nuclei, followed by fragmentation into apoptotic bodies). Histolysis happens in both species, between 22 and 23 h after pupation. There were no significant differences between the species studied. Apoptosis does not occur simultaneously in all cells. Cytoplasmic acid phosphatase activity gradually increases during development, suggesting the existence of acid phosphatases that are only expressed during the apoptotic stage. Twenty hours after pupation, salivary glands already show biochemical alterations relative to nuclear permeability such as acidification, possibly due to the fusion of lysosomes with the nucleus a few hours before apoptosis. Autophagy seems to act together with apoptosis and has a secondary role in cell death.

    2017-09-07

    Obesity is a major health concern in every US age group. Approximately one in 4 children in Arizona's Special Supplemental Nutrition Program for Women, Infants, and Children is overweight or obese. The Arizona Department of Health Services developed the Empower program to promote healthy environments in licensed child care facilities. The program consists of 10 standards, including one standard for each of these 5 areas: physical activity and screen time, breastfeeding, fruit juice and water, family-style meals, and staff training. The objective of this evaluation was to determine the level of implementation of these 5 Empower standards. A self-assessment survey was completed from July 2013 through June 2015 by 1,850 facilities to evaluate the level of implementation of 5 Empower standards. We calculated the percentage of facilities that reported the degree to which they implemented each standard and identified common themes in comments recorded in the survey. All facilities reported either full or partial implementation of the 5 standards. Of 1,678 facilities, 21.7% (n = 364) reported full implementation of all standards, and 78.3% (n = 1,314) reported at least partial implementation. Staff training, which has only one component, had the highest level of implementation: 77.4% (n = 1,299) reported full implementation. Only 44.0% (n = 738) reported full implementation of the standard on a breastfeeding-friendly environment. Arizona child care facilities have begun to implement the Empower program, but facilities will need more education, technical assistance, and support in some areas to fully implement the program.

  5. Late Paleozoic fusulinids from Sonora, Mexcio: importance for interpretation of depositional settings, biogeography, and paleotectonics

    Science.gov (United States)

    Stevens, Calvin H.; Poole, Forrest G.; Amaya-Martínez, Ricardo

    2014-01-01

    Three sets of fusulinid faunas in Sonora, Mexico, discussed herein, record different depositional and paleotectonic settings along the southwestern margin of Laurentia (North America) during Pennsylvanian and Permian time. The settings include: offshelf continental rise and ocean basin (Rancho Nuevo Formation in the Sonora allochthon), shallow continental shelf (La Cueva Limestone), and foredeep basin on the continental shelf (Mina México Formation). Our data represent 41 fusulinid collections from 23 localities with each locality providing one to eight collections. Reworked fusulinids in the Middle and Upper Pennsylvanian part of the Rancho Nuevo Formation range in age from Desmoinesian into Virgilian (Moscovian-Gzhelian). Indigenous Permian fusulinids in the La Cueva Limestone range in age from middle or late Wolfcampian to middle Leonardian (late Sakmarian-late Artinskian), and reworked Permian fusulinids in the Mina México Formation range in age from early to middle Leonardian (middle-late Artinskian). Conodonts of Guadalupian age occur in some turbidites in the Mina México Formation, indicating the youngest foredeep deposit is at least Middle Permian in age. Our fusulinid collections indicate a hiatus of at least 10 m.y. between the youngest Pennsylvanian (Virgilian) rocks in the Sonora allochthon and the oldest Permian (middle Wolfcampian) rocks in the region. Most fusulinid faunas in Sonora show affinities to those of West Texas, New Mexico, and Arizona; however, some genera and species are similar to those in southeastern California. As most species are similar to those east of the southwest-trending Transcontinental arch in New Mexico and Arizona, this arch may have formed a barrier preventing large-scale migration and mixing of faunas between the southern shelf of Laurentia in northwestern Mexico and the western shelf in the southwestern United States.

    Many developing countries have shown interest in embracing telemedicine and incorporating it into their healthcare systems. In 2000, the U.S. Army Yuma Proving Ground (YPG) initiated a program to assist the Republic of Panama in establishing a demonstration Panamanian rural telemedicine program. YPG engaged the Arizona Telemedicine Program (ATP) to participate in the development and implementation of the program. The ATP recommended adoption of a "top-down" strategy for creating the program. Early buy-in of the Panamanian Ministry of Health and academic leaders was regarded as critical to the achievement of long-term success. High-level meetings with the Minister of Health and the Rectors (i.e., Presidents) of the national universities gained early program support. A telemedicine demonstration project was established on a mountainous Indian reservation 230 miles west of Panama City. Today, three rural telemedicine clinics are linked to a regional Ministry of Health hospital for teleconsultations. Real-time bidirectional videoconferencing utilizes videophones connected over Internet protocol networks at a data rate of 768 kilobits per second to the San Felix Hospital. Telepediatrics, tele-obstetrics, telepulmonology, teledermatology, and tele-emergency medicine services became available. Telemedicine services were provided to the three sites for a total of 1,013 cases, with numbers of cases increasing each year. These three demonstration sites remained in operation after discontinuation of the U.S. involvement in September 2009 and serve as a model program for other telemedicine initiatives in Panama. Access to the assets of a partner-nation was invaluable in the establishment of the first model telemedicine demonstration program in Panama. After 3 years, the Panamanian Telemedicine and Telehealth Program (PTTP) became self-sufficient. The successful achievement of sustainability of the PTTP after disengagement by the United States fits the Latifi-Weinstein model

  13. Quaternary Geochronology, Paleontology, and Archaeology of the Upper San Pedro River Valley, Sonora, Mexico

    Gaines, E. P.

    2013-12-01

    This poster presents the results of multi-disciplinary investigations of the preservation and extent of Quaternary fossil-bearing strata in the San Pedro River Valley in Sonora, Mexico. Geologic deposits in the portions of the San Pedro Valley in southern Arizona contain one of the best late Cenozoic fossil records known in North America and the best record of early humans and extinct mammals on the continent. The basin in the U.S. is one of the type locations for the Blancan Land Mammal Age. Hemiphilian and Irvingtonian fossils are common. Rancholabrean remains are widespread. Strata in the valley adjacent to the international border with Mexico have yielded the densest concentration of archaeological mammoth-kill sites known in the western hemisphere. Despite more than 60 years of research in the U.S., however, and the fact that over one third of the San Pedro River lies south of the international boundary, little has been known about the late Cenozoic geology of the valley in Mexico. The study reported here utilized extensive field survey, archaeological documentation, paleontological excavations, stratigraphic mapping and alluvial geochronology to determine the nature and extent of Quaternary fossil-bearing deposits in the portions of the San Pedro Valley in Sonora, Mexico. The results demonstrate that the Plio-Pleistocene fossil -bearing formations known from the valley in Arizona extend into the uppermost reaches of the valley in Mexico. Several new fossil sites were discovered that yielded the remains of Camelids, Equus, Mammuthus, and other Proboscidean species. Late Pleistocene archaeological remains were found on the surface of the surrounding uplands. AMS radiocarbon dating demonstrates the widespread preservation of middle- to late- Holocene deposits. However, the late Pleistocene deposits that contain the archaeological mammoth-kill sites in Arizona are absent in the valley in Mexico, and are now known to be restricted to relatively small portions of

    Young people can be valuable motivational resources for health promotion. A project implemented from 2009 through 2013 in a small American Indian community in northwest Arizona recruited American Indian young people aged 10 to 21 as agents of change for health promotion through radio programming. Thirty-seven participants were recruited and trained in broadcasting and creative writing techniques; they produced and aired 3 radio dramas. In post-project evaluation, participants were confident they could influence community behaviors but thought that training techniques were too similar to those used in school activities and thus reduced their drive to engage. Effective engagement of young people requires creativity to enhance recruitment, retention, and impact.

  18. Stratigraphy and paleontology of Lower Permian rocks north of Cananea, northern Sonora, Mexico

    Science.gov (United States)

    Blodgett, R.B.; Moore, T.E.; Gray, F.

    2002-01-01

    Lower Permian carbonate and overlying red bed clastic rocks are present in a 2 km2 stratigraphic window in the vicinity of Rancho La Cueva, Santa Cruz sheet (scale 1:50,000), northern Sonora, Mexico. This exposure lies unconformably beneath predominantly intermediate Upper Cretaceous volcanics yielding 40Ar/39Ar ages of 73.4?? 0.18 and 71.1 ?? 0.35 Ma. The lower part of the Permian succession consists of light- to medium-gray colored limestones of the Colina Limestone, with a minimum thickness of 235 m. Sedimentary features suggest shallow water, slightly restricted depositional environments. Although lacking observable fossils for the most part, two intervals of richly fossiliferous, silicified shell beds are present near the base and top of the Colina Limestone. The lower fauna consist mostly of gastropods and bivalves. The presence of a new microdomatid gastropod species. Glyptospira sonorensis n. sp., close to Glytospira arelela Plas, suggests a late Wolfcampian age for this horizon. The upper fauna are predominantly molluscan dominated (gastropods and bivalves), but some brachiopods (productids and the rhynchonellid genus Pontisia) are also present. Gastropod genera include Bellerophon, Warthia, Euomphalus (represented by the species, Euomphalus kaibabensis Chronic), Baylea, Worthenia, Naticopsis, Goniasma, Kinishbia, Cibecuia, and Glyptospira. The gastropods suggest a Leonardian (late Early Permian) age for this horizon, and many of the species have previously been recorded from the Supai Group and Kaibab Formation of northern and central Arizona. The Colina Limestone is conformably overlain by 11.2 m of light-gray lime mudstone and dolostone, assigned here to the Epitaph Dolomite, which in turn is succeeded by 58.8 m of red-colored sandstone and gray lime mudstone, assigned here to the Scherrer Formation. This Lower Permian succession is significant because it further strengthens the stratigraphic ties of southeastern Arizona rocks with those of northern

  19. Arizona black rattlesnake (Crotalus viridis cerberus)

    Science.gov (United States)

    Nowak, Erika M.

    2006-01-01

    The Arizona black rattlesnake makes its home at higher elevations in Arizona and far western New Mexico. The snake's use of high-altitude habitat and its black coloration as an adult distinguishes it from other subspecies of the western rattlesnake (Crotalus viridis), which prefer lower elevations and range from tan to reddish in color as adults. These physical and habitat differences are also reflected in genetic differences that suggest that the Arizona black rattlesnake may be a new species of rattlesnake. Despite the species's limited range, basic biological information needed to make management decisions is lacking for most Arizona black rattlesnake populations. To address this need, U.S. Geological Survey (USGS) scientists conducted research on the species in Arizona national park units from 2003 to 2005. The research examined relative population abundance, movement patterns, range requirements, dietary habits, and winter and summer habitat. Research in Arizona national parks was made possible through the support of the Western National Parks Association, Tonto National Monument, and the USGS Science Internships for Workforce Diversity Program. Importantly, the park-based research was used to augment a long-term mark-recapture study of the species that has been conducted by USGS biologists at sites near Flagstaff, Arizona, since 1999. USGS researchers were the first to conduct extensive studies of this species in the wild.

    They may be working in 1 of the richest countries of the world, but the conditions endured by Mexican farmworkers in the US southwest are deplorable. Many of their hardships arise from the fact that many are undocumented. The advantage of these workers to employers and to the economy is that they can be let go when they are no longer needed, and in many instances they are then deported. The unsanitary conditions on the farms they work on make the workers' infection and disease rates comparable to those of many developing countries that have nowhere near the resources of the US. The refusal of the US government to pass legislation enforcing a code of sanitary conditions for farm labor and its toleration of a market in which humans are the primary commodity, call attention to the disregard the authorities have for these workers as human beings. The union has a variety of programs to assist migrant farmworkers with such necessities as shelter, food, and clothing when needed, with translation and with referral services, and recently it has assisted in establishing a primary health care facility and a legal project for undocumented workers. The 2 particularly innovative elements to this union's activities are: 1) the creation of a "sister organization" south of the border, and 2) the generation of specific economic development projects in Mexico.

  7. Provenance and U-Pb geochronology of the Upper Cretaceous El Chanate Group, northwest Sonora, Mexico, and its tectonic significance

    2009-01-01

    The Upper Cretaceous El Chanate Group, northwest Sonora, Mexico, is a 2.8km thick clastic sedimentary sequence deposited in a continental basin closely related to volcanic activity. It consists of three formations: the Pozo Duro (oldest), the Anita, and the Escalante (youngest). Petrographic study, conglomerate pebble counts, and U-Pb geochronology of detrital zircons were performed to determine the source and age of this sequence, and to interpret its tectonic setting. In the sandstones of all three formations, the most abundant grains are those of volcanic composition (Q38F22L 40, Q35F19L46, and Q 31F22L47, respectively). The Pozo Duro Formation includes well-rounded quartz-arenite clast conglomerates, whereas conglomerates of the two upper units have clasts predominantly of andesitic and rhyolitic composition. The most likely source for these sediments was the Jurassic volcanic arc exposed in northern Sonora and southern Arizona. Zircons from five sandstone samples define two main age groups, Proterozoic and Mesozoic. The first ranges mostly from 1000 to 1800Ma, which suggests the influence of a cratonic source. This zircon suite is interpreted to be recycled and derived from the same source area as the quartz-rich sandstone clasts in the basal part of the section. Mesozoic zircons range from Triassic to Late Cretaceous, which confirms the proposed Late Cretaceous age for the sequence, and also corroborates Jurassic felsic source rocks. Another possible source was the Alisitos volcanic arc, exposed along the western margin of the Baja California Peninsula. Of regional significance is the great similarity between the El Chanate Group and the McCoy Mountains Formation of southeastern California and southwestern Arizona. Both are Cretaceous, were deposited in continental environments, and have similar zircon-age patterns. Also, both exhibit intense deformation and locally display penetrative foliation. These features strongly suggest that both units underwent

    2009-01-01

    Full Text Available Situated in the topographically complex transition between the Neotropics and the temperate biomes of North America,the state of Sonora, Mexico, has an extraordinarily diverse herpetofauna. Surprisingly little research has been conductedon the state’s amphibians and reptiles and many systematic and biogeographic questions remain unanswered. Tofacilitate future research, we provide a checklist of Sonora’s herpetofauna, documenting species presence based onmuseum specimens, our fieldwork, and published research. Sonora’s herpetofauna is placed in a regional biogeographicperspective via a checklist for the six adjoining states together with faunal analyses. A total of 402 species ofamphibians and reptiles are recorded from these seven states. Sonora has the greatest species richness (187 species,followed by Chihuahua (169 species, and Sinaloa (146 species. Sonora's herpetofauna is most similar to that ofChihuahua, with which it shares a long border. Eleven biogeographic affinity-based faunal groups are recognized. Ofthese, three are dominant in Sonora: a core group classified as "Sonoran" demonstrates strong affinity to SonoranDesertscrub and Sinaloan Thornscrub communities; a Tropical group - with many species reaching their northerndistributional limits in the state; and a Madrean group consisting largely of montane species. Our state-level faunalanalysis provides some evidence of peninsular depauperization of the herpetofauna on the Baja California peninsula duein part to the small number of Neotropical species present in Baja California Sur. Our faunal analysis points towarddistinctive mainland and peninsular Sonoran Desert herpetofaunas centered on Sonora and the Baja CaliforniaPeninsula, respectively, each with about 50 non-insular species, and each with species-level endemism nearing 50%.

    2012-12-01

    To commemorate the once-in-a-lifetime event of Arizona's hundredth birthday, the Centennial Commission and the Governor of Arizona envisioned a museum and companion website that would capture the state's history, celebrate its people, and embrace its future. Working with world-renowned museum designers, the state began to seek ideas from across Arizona to create plans for a journey of discovery through science and the humanities. The museum would introduce visitors to some of the people who nurtured the state through its early years and others who are innovating its tomorrows. Showcases would include the resources and experiences that shaped the state's history and are transforming its present day, highlighting the ingenuity that tamed the wild frontier and is envisioning Arizona's next frontiers through science and technology. The Arizona Experience (www.arizonaexperience.org) was initially intended to serve as the web presence for the physical museum, but as delays occurred with the physical museum, the site has quickly developed an identify of its own as an interactive, multimedia experience, reaching a wider audience with functions that would be difficult or expensive to produce in a museum. As leaders in scientific and technological innovation in the state, the Arizona Geological Survey was tasked with designing and creating the Arizona Experience site. The general themes remain the same; however, the site has added content and applications that are better suited to the online environment in order to create a rich, dynamic supplement to a physical museum experience. The website offers the features and displays of the future museum with the interactive nature and learning environment of the web. This provides an encyclopedic overview of the State of Arizona by subject matter experts in a manner that is free and open to the public and erases socio-economic, political, and physical boundaries. Over the Centennial Year of 2012 the site will release a new theme and

  15. Knowledge and beliefs about dengue transmission and their relationship with prevention practices in Hermosillo, Sonora, Mexico: A qualitative assessment

    Directory of Open Access Journals (Sweden)

    Carmen eArellano

    2015-06-01

    Full Text Available Background: Dengue is an emerging threat in the U.S.-Mexico border region. Transmission has regularly occurred in Sonora, MX since 1982 but it was not until 2014 that cities directly on the Arizona-Sonora border had local transmission. One of the closest urban areas to have regular seasonal transmission is Hermosillo, SN, MX. Developing a better understanding of the knowledge and perceptions of dengue in close geographic proximity to the border can identify areas to target for prevention and control measures. Methods: We conducted focus groups in six neighborhoods in Hermosillo, SN; three with high dengue transmission and three with lower transmission. Awareness of dengue and experience with dengue was common. Results: In all focus groups discussants reported knowing someone personally who had past dengue infection. We further identified several keys ways that the perceptions of dengue transmission could influence the effectiveness of dengue control campaigns. First, there was confusion about how dengue is transmitted. While people associated dengue with mosquitoes, multiple modes of transmission were perceived including direct person to person transmission. In one focus group discussants indicated a stigma surrounding dengue infection. The necessity to maintain cleanliness in their households was identified as a primary strategy to fight dengue, however, participants also noted the limited impact their actions may have on transmission if there is lack of community support or governmental infrastructure to control neighboring and public spaces. Conclusion: As dengue moves further northward, more efforts should be made to clarify the dynamics of transmission to avoid the development of stigma and more coordinated efforts should be made to not only control but to prevent dengue.

    A program model has been developed and implemented over the last three years to provide a robust optical technologybased science education program to students aged 9-11 years (5th grade), a formative time in the development of a student's interest in science and engineering. We have created well-tested and evaluated teaching kits for the classroom to teach about the basics of image formation and telescopes. In addition we provide professional development to the teachers of these students on principles of optics and on using the teaching kits. The program model is to reach every teacher and every student in a number of mid-sized rural communities across the state of Arizona. The Galileoscope telescope kit is a key part of this program to explore optics and the nature of science. The program grew out of Module 3 of the NSF-Supported Hands-On Optics project (SPIE, OSA, and NOAO) and from the Science Foundation Arizona-supported Hands-On Optics Arizona program. NOAO has conducted this program in Flagstaff, Yuma, Globe, and Safford, Arizona and is being expanded to sites across the entire state of Arizona (295,254 square kilometers). We describe the educational goals, evaluations, and logistical issues connected to the program. In particular, we proposed that this model can be adapted for any rural or urban locations in order to encourage interest in science, astronomy and optics.-

  17. Food habits of pumas in northwestern Sonora, Mexico

    2003-01-01

    It is questionable whether food-habits studies of pumas conducted in the southwestern United States can be extrapolated to northwestern Mexico, because of differences in management, distribution, and abundance of wildlife. We determined food habits of pumas (Puma concolor) in the Sonoran Desert of northwestern Sonora, Mexico. Based on studies in the western United States, we hypothesized that desert mule deer (Odocoileus hemionus) were the major food source of pumas in Sonoran Desert habitats of Mexico. The study area supports populations of desert mule deer, white-tailed deer (Odocoileus virginianus), lagomorphs (Lepus spp. and Sylvilagus audubonii), collared peccary (Pecari tajacu), and the largest population (???300 individuals) of desert bighorn sheep (Ovis canadensis) in Sonora. Based on pugmark characteristics, we recorded 3 different adult resident pumas in approximately 90 km2. We analyzed 60 puma fecal samples collected September 1996-November 1998. Primary prey items based on frequency of occurrence and estimated biomass consumed were desert bighorn sheep (40% and 45%, respectively), lagomorphs (33%, 19%), deer (17%, 17%), and collared peccary (15%, 11%). The high percentage of desert bighorn sheep in puma diets may be due to high abundance relative to mule deer, which declined in number during our study. No differences were found in puma diets between seasons (??22=2.4526, P=0.2934). Fluctuations in mule deer populations in northwestern Sonora may influence prey selection by pumas.

  7. Isotopic, geochemical, and temporal characterization of Proterozoic basement rocks in the Quitovac region, northwestern Sonora, Mexico: Implications for the reconstruction of the southwestern margin of Laurentia

    Science.gov (United States)

    Iriondo, A.; Premo, W.R.; Martínez-Torres, Luis M.; Budahn, J.R.; Atkinson, William W.; Siems, D.F.; Guaras-Gonzalez, B.

    2004-01-01

    A detailed geochemical characterization of 19 representative Proterozoic basement rocks in the Quitovac region in northwestern Sonora, Mexico, has identified two distinct Paleoproterozoic basement blocks that coincide spatially with the previously proposed Caborca and "North America" blocks. New U-Pb zircon geochronology revises their age ranges, the Caborca (1.78-1.69 Ga) and "North America" (1.71-1.66 Ga) blocks at Quitovac, and precludes a simple age differentiation between them. In addition, Grenvillian-age granitoids (ca. 1.1 Ga), spatially associated with the Caborca block have been identified at Quitovac. Nd isotopes and major- and trace-element geochemistry support the distinction of these Paleoproterozoic blocks. Granitoids of the "North America" block are characterized by depleted ??Nd values (3.4-3.9) and younger Nd model ages (1800-1740 Ma) and have lower K2O, Y, Rb, Ba, Th, REE, and Fe/Mg values than coeval rocks of the Caborca block. The Caborca block granitoids are likewise characterized by slightly less depleted ??Nd (0.6-2.6) and older Nd model ages (2070-1880 Ma). Despite the subtle differences, granitoids from both the Caborca and "North America" blocks exhibit island arc-like affinities. We propose that the Proterozoic basement rocks from the Quitovac region are an extension of the Proterozoic crustal provinces in the southwestern United States. Specifically, rocks of the Caborca block exhibit an affinity to rocks of either the Yavapai province or the Mojave-Yavapai transition zone, whereas rocks of the "North America" block have signatures similar to those of the Mazatzal province or possibly the Yavapai province of Arizona. The new isotopic ages and geochemical data do not support the existence of the Late Jurassic Mojave-Sonora megashear at Quitovac, as originally proposed. However, the Quitovac region accounts only for a small fraction of the Proterozoic basement in Sonora, so these findings do not eliminate the possibility of a megashear

    2014-01-01

    Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources; they are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. By recognizing the spatial differences in the capacities and potentials of ecosystems, ecoregions stratify the environment by its probable response to disturbance. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The Arizona ecoregion map was compiled at a scale of 1:250,000. It revises and subdivides an earlier national ecoregion map that was originally compiled at a smaller scale. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of the spatial patterns and the composition of biotic and abiotic phenomena that affect or reflect differences in ecosystem quality and integrity. These phenomena include geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another regardless of the hierarchical level. A Roman numeral hierarchical scheme has been adopted for different levels of ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions. At level III, the continental United States contains 105 ecoregions and the conterminous United States has 85 ecoregions. Level IV is a further subdivision of level III ecoregions. Arizona contains arid deserts and canyonlands, semiarid shrub- and grass-covered plains, woodland- and shrubland-covered hills, lava fields and volcanic plateaus, forested mountains, glaciated

    Full Text Available A small assemblage of extremely well-preserved fragments of new sponges has been discovered in calcipelites of the middle Cambrian El Mogallón Formation in the Cerro El Mogallón section, near Arivechi in eastern Sonora, Mexico. The assemblage includes two new reticulosan species referred to Ratcliffespongia arivechensis sp. nov. and Valospongia sonorensis sp. nov., combined with disarticulated remains assigned to Kiwetinokia and additional, currently unidentifiable taxa. The new species represent the first records of these Cambrian genera from Mexico, although they are widely distributed at low latitudes, being previously best known from Utah but extending through Laurentia and South China. This middle Cambrian fauna indicates that there was considerable continuity of the deeper-water hexactinellid sponges between the warm peri-platform of Laurentia and the peri-continental Cambrian platform of Sonora. The new material supports the impression of extremely wide distribution of Cambrian sponge genera, with local diversification at species level within regions, in contrast to much greater generic-level endemism during the Ordovician Period.

    Pediatric obesity has become a problem of epidemic proportions, due to the inadequate and excessive consumption of food, sedentary lifestyle, and the restricted socio-economic development. This causes a major risk in health complications that have an effect on the psychological and social spheres of the child, which makes him endure such diseases as depression and anxiety. The aim of this study was to determine the association between depression and the nutritional status of schoolchildren from a family medicine unit in Sonora. Cross-sectional study performed during 2011 in 101 schoolchildren from Sonora. Kovacs test was applied to detect depressive symptoms; nutritional status was determined by weight and height; body mass index was calculated according to the Center for Disease Control and Prevention (CDC) percentiles. The results were analyzed in SPSS version 18 using Mann-Whitney U and chi-square. Of all the patients with depression, 19 were obese; the other 10 showed a normal nutrition status. Patients with low weight did not show depression. The odds ratio (OR) for depression in students with obesity was 3.16, 95 % CI = 1.13, 7.12. The detection and management of depression should be considered in the treatment of obesity.

    Full Text Available This paper shows the use and value of natural resources from a social, sustainable and legal perspective, under the scheme of Sustainable Forest Management Units (UMAFOR by its Spanish acronym. Two participatory workshops were carried out in March 2010, one in UMAFOR Sierra La Madera and another in UMAFOR Sierra Alta, belonging to the Sierra de Sonora. An adaptation of “Problems, Causes and Consequences” of Ramírez-García (2004 methodology was used to discuss issues such as conservation, productive activities, society, laws, research and support programs. The objective was to analyze challenges and opportunities in the Sierra de Sonora under this management scheme. The ratting of natural resource for inhabitant and producers was documented based in ecosystems type and its value for use. Economic value was the most important for productive and non productive use; however, there are opportunities to transit from traditional to sustainable activities. Local producers are interested in linking whit research centers and consultants to get support for diversification of productive activities. It is possible to have changes according to sustainable development; UMAFOR is an alternative to achieve those changes.

    Full Text Available The aim of this paper is to ascertain the territorial dimension of the fishing economy in Guaymas, Mexico. The geographical studies addressing this economic activity in Mexico and published in the last decades are scarce. For this reason, this research work is particularly important, as it outlines the fishery activities in one of the most active sea-ports of northwest Mexico, from a territorial perspective. The first part of this article explains why and how Economic Geography addresses fishery activities and which methodology we pursued to carry out this investigation, based on studies carried out by geographers, particularly in France and Argentina. Then the paper describes the natural conditions prevailing in the Gulf of California (also known as Sea of Cortez, a large inlet of the eastern Pacific Ocean that is rich in marine resources and where most of the main national fisheries are located. Guaymas is one of the most important sea ports located along the Gulf of California for its long fishing history and the variety of fishing species captured. This port, located in the southern coast of the state of Sonora, is a mediumsized city with a little over 100 thousand inhabitants; a considerable proportion of the local labor force works in the fishery sector and associated industries. Today, the fishery sector in Guaymas is characterized by a large number of artisan fishermen, a prominent fleet preciand the regular practise of illegal catching. This port is the seat of large enterprises, such as Ocean Garden, involved in the industrialization of catches (basically fish oil and fish meal and their further commercialization within and outside Mexico. Two commercially important species have played a key role in the evolution and outline of the current territorial structure of fisheries in Guaymas. One is shrimp, with a fishery that recorded a boom during 1970-1990, bringing along a number of benefits for local fishermen in Sonora. This fishery

    Full Text Available A relação entre música e política sempre esteve presente nas manifestações sonoras de nosso país. As opções e acontecimentos políticos repercutem nas obras dos compositores. Estes, por sua vez, tendem a discutir e criticar esses acontecimentos, pela sátira inclusa nas marchinhas carnavalescas, por mensagens subliminares ou até mesmo de forma direta. A partir do período do Estado Novo (1937-1945, a interferência de censores torna-se clara em relação às mensagens contidas nas canções. O Departamento de Imprensa e Propaganda (DIP controla, por meio de cooptação e repressão, os ímpetos crítico musicais dos compositores. O período da ditadura militar brasileira é marcado pela censura, repressão e cerceamento à liberdade de expressão. Muitos artistas, diante das violências praticadas contra a crítica na criação artística, se mobilizam em oposição à ditadura, pela criação de canções de protesto velado, inserido nas mensagens subliminares, como na obra de Chico Buarque de Hollanda, ou de forma direta, a exemplo da canção Prá não dizer que não falei das flores, de Geraldo Vandré. Analisamos neste artigo o ambiente musical brasileiro entre 1964 e 1985, pelo viés de olhar dos compositores e da censura e as especificidades de cada movimento musical, que tecem a trama das identidades sonoras nesse momento tão rico e criativo da música popular brasileira.

  6. Evaluation of Arroyo Channel Restoration Efforts using Hydrological Modeling: Rancho San Bernardino, Sonora, MX

    2012-12-01

    In the drylands of the southwestern U.S. and northwestern Mexico, historical river channel incision (arroyo cutting) has led to the destruction of riparian ecological systems and cieñega wetlands in many locations. Along Silver Creek on the Arizona-Sonora border, the Cuenca Los Ojos Foundation has been installing rock gabions and concrete and earthen berms with a goal of slowing flash floods, raising groundwater levels, and refilling arroyo channels with sediment in an area that changed from a broad, perennially wet cieñega to a narrow sand- and gravel-dominated arroyo channel with an average depth of ~6 m. The engineering efforts hope to restore desert wetlands, regrow riparian vegetation, and promote sediment deposition along the arroyo floor. Hydrological modeling allows us to predict how rare flood events interact with the restoration efforts and may guide future approaches to dryland ecological restoration. This modeling is complemented by detailed topographic surveying and use of streamflow sensors to monitor hydrological processes in the restoration project. We evaluate the inundation associated with model 10-, 50-, 100-, 500-, and 1,000-year floods through the study area using FLO-2D and HEC-RAS modeling environments in order to evaluate the possibility of returning surface inundation to the former cieñega surface. According to HEC-RAS model predictions, given current channel configuration, it would require a 500-year flood to overtop the channel banks and reinundate the cieñega (now terrace) surface, though the 100-year flood may lead to limited terrace surface inundation. Based on our models, 10-year floods were ~2 m from overtopping the arroyo walls, 50-year floods came ~1.5 m from overtopping the arroyos, 100-year floods were ~1.2 m from overtopping, and 500- and 1,000-year floods at least partially inundated the cieñega surface. The current topography of Silver Creek does not allow for frequent flooding of the former cieñega; model predictions

    These are the results of a prospective, multicentric study carried out in five institutional hospitals in Sonora and Sinaloa, using Karmann syringe and cannulae for manual intrauterine aspiration in cases of incomplete abortion, dead and retained ovum, hidatiform mola and endometrial biopsy. Management data in 1046 patients, are described; methodology is shown, and demonstrating that it converts uterine emptying is a simple, efficacious and economical procedure, with a very low risk and it allows these patients management in an ambulatory way. From these results, and as it is demonstrated in the study, institutions may increase their programable resources as to amount of disposable beds, for other type of patients, and the offering of attention by surgeon, anesthetist, nurse and medication, as their hospital stay is minimal, and in most of the cases active anesthetist participation is not required. In the same way, it permits the patient a better relationship with the personal of the institution, and so, a more human care and the possibility of reintegrating the patient to a familiar environment, rapidly, and in good psychical and physical conditions.

  15. Developing spatially explicit footprints of plausible land-use scenarios in the Santa Cruz Watershed, Arizona and Sonora

    The SLEUTH urban growth model is applied to a binational dryland watershed to envision and evaluate plausible future scenarios of land use change into the year 2050. Our objective was to create a suite of geospatial footprints portraying potential land use change that can be used to aid binational decision-makers in assessing the impacts relative to sustainability of natural resources and potential socio-ecological consequences of proposed land-use management. Three alternatives are designed to simulate different conditions: (i) a Current Trends Scenario of unmanaged exponential growth, (ii) a Conservation Scenario with managed growth to protect the environment, and (iii) a Megalopolis Scenario in which growth is accentuated around a defined international trade corridor. The model was calibrated with historical data extracted from a time series of satellite images. Model materials, methodology, and results are presented. Our Current Trends Scenario predicts the footprint of urban growth to approximately triple from 2009 to 2050, which is corroborated by local population estimates. The Conservation Scenario results in protecting 46% more of the Evergreen class (more than 150,000 acres) than the Current Trends Scenario and approximately 95,000 acres of Barren Land, Crops, Deciduous Forest (Mesquite Bosque), Grassland/Herbaceous, Urban/Recreational Grasses, and Wetlands classes combined. The Megalopolis Scenario results also depict the preservation of some of these land-use classes compared to the Current Trends Scenario, most notably in the environmentally important headwaters region. Connectivity and areal extent of land cover types that provide wildlife habitat were preserved under the alternative scenarios when compared to Current Trends.

    2006-01-01

    Northern Arizona is best known for the Grand Canyon. Less widely known are the hundreds of geologically young volcanoes, at least one of which buried the homes of local residents. San Francisco Mtn., a truncated stratovolcano at 3887 meters, was once a much taller structure (about 4900 meters) before it exploded some 400,000 years ago a la Mt. St. Helens. The young cinder cone field to its east includes Sunset Crater, that erupted in 1064 and buried Native American homes. This ASTER perspective was created by draping ASTER image data over topographic data from the U.S. Geological Survey National Elevation Data. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.

    Geologic mapping in the northern Sierra Los Ajos reveals new stratigraphic and structural data relevant to deciphering the Mesozoic-Cenozoic tectonic evolution of the range. The northern Sierra Los Ajos is cored by Proterozoic, Cambrian, Devonian, Mississippian, and Pennsylvanian strata, equivalent respectively to the Pinal Schist, Bolsa Quartzite and Abrigo Limestone, Martin Formation, Escabrosa Limestone, and Horquilla Limestone. The Proterozoic-Paleozoic sequence is mantled by Upper Cretaceous rocks partly equivalent to the Fort Crittenden and Salero Formations in Arizona, and the Cabullona Group in Sonora, Mexico. Absence of the Upper Jurassic-Lower Cretaceous Bisbee Group below the Upper Cretaceous rocks and above the Proterozoic-Paleozoic rocks indicates that the Sierra Los Ajos was part of the Cananea high, a topographic highland during the Late Jurassic and Early Cretaceous. Deposition of Upper Cretaceous rocks directly on Paleozoic and Proterozoic rocks indicates that the Sierra Los Ajos area had subsided as part of the Laramide Cabullona basin during Late Cretaceous time. Basal beds of the Upper Cretaceous sequence are clast-supported conglomerate composed locally of basement (Paleozoic) clasts. The conglomerate represents erosion of Paleozoic basement in the Sierra Los Ajos area coincident with development of the Cabullona basin. The present-day Sierra Los Ajos reaches elevations of greater than 2600 m, and was uplifted during Tertiary basin-and-range extension. Upper Cretaceous rocks are exposed at higher elevations in the northern Sierra Los Ajos and represent an uplifted part of the inverted Cabullona basin. Tertiary uplift of the Sierra Los Ajos was largely accommodated by vertical movement along the north-to-northwest-striking Sierra Los Ajos fault zone flanking the west side of the range. This fault zone structurally controls the configuration of the headwaters of the San Pedro River basin, an important bi-national water resource in the US

    Full Text Available Judicial performance evaluations are a relatively new tool for assessing judges and providing information to voters to help them determine whether to retain judges in contested or retention elections. Arizona implemented its judicial evaluation program about 20 years ago, and since that time, the state has continually strived to improve its process. The result is that today Arizona has one of the most progressive and comprehensive judicial performance evaluation programs in the United States. This article takes a critical look at the strengths and weaknesses of Arizona’s program, keeping in mind two key values that the system seeks to protect: judicial accountability and judicial independence. Las evaluaciones del rendimiento judicial son una herramienta relativamente nueva para evaluar a los jueces y ofrecer información a los votantes, que les ayude a decidir si quieren reelegir a los jueces en las elecciones. Arizona implementó su programa de evaluación judicial hace unos 20 años, y desde ese momento, el Estado se ha esforzado continuamente en mejorar el proceso. El resultado es que hoy en día, Arizona tiene uno de los programas de evaluación del rendimiento judicial más progresistas e integrales de los Estados Unidos. Este artículo ofrece una mirada crítica a las fortalezas y debilidades del programa de Arizona, teniendo en cuenta dos valores clave que el sistema trata de proteger: la responsabilidad judicial y la independencia judicial.

    Full Text Available Este artículo presenta los resultados de una investigación sociológica cuyo objeto fue explorar el papel que ha jugado el modelo hegemónico de masculinidad en la ocurrencia de muertes derivadas de accidentes y varias formas de ejercicio de la violencia en una comunidad rural de la sierra de Sonora. Estos resultados difieren de aquellos que tradicionalmente los estudios de las masculinidades han mostrado para México y América Latina. El modelo dominante de masculinidad en las comunidades estudiadas no ha condicionado significativamente la ocurrencia de las muertes por accidentes y otras causas violentas. La responsabilidad, la disciplina y el respeto hacia las personas consideradas socialmente débiles (mujeres, ancianos y niños, principalmente son características que debe poseer un hombre de verdad en las comunidades estudiadas. El apego de los hombres a estas formas de comportamiento y su temor a perder honorabilidad como hombre de verdad si se desvían de estas normas de conducta los ha llevado a evitar una serie de prácticas temerarias que pudieron poner en riesgo su vida y la de otras personas.

  6. Perception on the Risk of the Sonora River Pollution

    2017-02-01

    Full Text Available This study applies the “psychometric paradigm” of risk perception to the heavy mineral spill in the Sonora River (Mexico. A total of 241 inhabitants of the polluted area with a mean age of 46.3 years participated in the study, completing an interview questionnaire at the onset of the disaster. The results allow us to establish a profile of the 18 characteristics comprising the model and a multiple regression analysis shows that some characteristics of the dimensions of dread risk and unknown risk explain a percentage of the magnitude of the perceived risk. In addition, the behaviors recommended by the authorities were classified by the participants according to their estimated usefulness. Significant differences were observed. Avoiding contact with the water was considered the most effective, followed by recommendations on the use of the water, with actions related to the environment and how to avoid pollution being considered the least effective. In sum, the strategy deployed allows us to observe how the victims perceive the disaster and organize the behaviors proposed by the authorities.

    2017-01-01

    The Chikungunya is an arbovirus first described during a 1952 outbreak of febrile exantematic disease in southern Tanganyika (now Tanzania). It is a virus within the alphavirus genus of the Togaviridae family, it is usually transmitted to humans by Aedes mosquitoes. Typically, the disease manifests as acute onset of fever and joint pains. This study describes the clinical characteristics the first imported case infected with chikungunya fever (CHIK) in Hermosillo, Sonora, Mexico. We report the case of a 30 years old man seen in our emergency department due to fever, polyarthralgia, rash and headache. This patient has been in Tapachula, Chiapas, a jungle area in southern México, and he returned from a 45 days trip before the onset his symptoms. The chikungunya viral infection (CHIK) was diagnosed by RT-PCR procedure. Paracetamol therapy was administered and his clinical course was self-limited. We concluded that with the increase of mosquito´s habitat by global warming and frequent traveling, CHIK reemerged and showed global distribution recently. This disease must be suspected in patients with compatible clinical symptoms returning from epidemic/endemic areas. CHIK must be diagnosed on the basis of clinical, epidemiological and laboratory criteria.

    Full Text Available Arizona’s first Teen Institute (TI program, Youth Empowered for Success, began in July 2004. It is the first TI-based project to focus on nurturing resilience via Health Realization (Pransky, 2007. The YES program’s design to “create conditions for success” in high schools is discussed. YES utilizes a strengths-based, multi-faceted approach of (1 teaching participants how to access their innate resilience and common sense (Health Realization, (2 training them in community development for school culture change and (3 helping them develop meaningful partnerships with adults. YES also expands upon the TI model by providing staff support for community development throughout the academic year. It is hypothesized that these efforts ultimately will increase overall well-being and reduce the incidence of alcohol, tobacco and other drug use (ATOD as well as depression and suicide among youth.

    Full Text Available Este artículo describe los fenómenos lingüísticos —desde el punto de vista lexicográfico— de la lengua especializada que utilizan los pescadores del estado de Sonora. Mediante la aplicación de un cuestionario que rebasa las 390 preguntas y con la utilización del método de “ palabras y cosas”, se explora exhaustivamente el léxico pesquero de once poblaciones —puertos de altura y campamentos— sonorenses y se comparan entre sí con el objeto de hallar la extensión real y la vitalidad de cada uno de los términos marinos; a si mismo, y con los mismos objetivos, se contrasta la nómina obtenida con otros sitios de México, América y España. El léxico patrimonial sonorense puede ser vislumbrado así a la luz de los contrastes que se establecen entre éste y las otras formas usadas por los pescadores del vasto mundo hispánico. De las múltiples denominaciones propias de la actividad pesquera y al tratarse de una muestra, se expone únicamente un filón de nueve centros de interés —el mar, meteorología, los astros, geomorfología, navegación y maniobras, jarcias, embarcaciones y construcción naval, artes de pesca y el comercio— de los diez en los que está dividido el cuestionario.

    2017-01-01

    Full Text Available En México, la violencia se ha incrementado exponencialmente en los últimos años; representa un constructo social con elementos multifactoriales y multicausales que, para erradicarse se deben contener y controlar con medidas de prevención y participación ciudadana. El objetivo de este artículo es determinar la influencia de la acción colectiva y la cooperación y también la cohesión e inclusión social sobre la confianza institucional, y a su vez sobre la violencia estructural generada por el proceso de inmigración y deportación en Nogales, Sonora. Para contrastar las hipótesis formuladas se aplicó un instrumento estadístico a una muestra aleatoria-estratificada en las colonias más violentas de esta ciudad fronteriza. Los resultados demostraron que la confianza y solidaridad de los habitantes es mayor hacia las instituciones públicas: gobierno local, central e instancias policiacas; en cambio, no confían tanto en las instituciones educativas (profesores y de seguridad social (enfermeras y médicos. Sin embargo, a partir de un análisis de medias aritméticas, con muestras separadas por rango de edad, se demostró que en todas las categorías de edad se confiaba más en las enfermeras y médicos y los profesores. También, se puso de manifiesto que tanto hombres como mujeres confían más en los trabajadores de la salud y la educación.

    Full Text Available Si bien es cierto que el fenómeno del comportamiento infractor ha sido abordado ya desde diferentes ángulos de la criminología, el presente artículo pretende ir más allá de lo ya dicho, enfatizando la dimensión de género, particularmente la identidad de género de los varones como explicación de los índices de la infracción de menores. El artículo es el resultado de una investigación de tipo cuantitativo sobre la situación de las y los menores infractores que entre los años de 1995 a 1999 estuvieron sujetos a procedimiento tutelar por el Consejo Tutelar para Menores (COTUME en la ciudad de Hermosillo, Sonora, México. Su contenido se estructura tomando en cuenta, primeramente, la explicación del fenómeno de la criminalidad de las y los menores desde la perspectiva de género, para continuar con una breve explicación de la metodología implementada en la investigación, proceder con el análisis de los resultados de la misma y finalizar con las conclusiones a las que se llegó. El tema de la violencia es sumamente complejo, requiere por consiguiente de estudios más amplios que lo que presenta esta investigación; sin embargo, ésta ofrece una visión que para muchos se ha mantenido oculta.

    1987-01-01

    The N aquifer is an important source of water in the 5,400 sq-mi Black Mesa area on the Navajo and Hopi Indian Reservations. The Black Mesa monitoring program is designed to monitor long-term effects on the groundwater resources of the mesa as a result of withdrawals from the aquifer by the strip-mining operation of Peabody Coal Company. Withdrawals from the N aquifer by the mine increased from 95 acre-ft in 1968 to more than 4,480 acre-ft in 1986. Water levels in the confined area of the aquifer declined as much as 90 ft from 1965 to 1987 in some municipal and observation wells within about a 15-mi radius of the mine well field. Part of the drawdown in municipal wells is due to local pumpage. Water levels have not declined in wells tapping the unconfined area of the aquifer. Chemical analyses indicate no significant changes in the quality of water from wells that tap the N aquifer or from springs that discharge from several stratigraphic units, including the N aquifer, since pumping began at the mine.

    Full Text Available Abstract Background This paper presents findings from the Tobacco Control in Arizona Healthcare Systems Survey, conducted in 2000. The purpose of the survey was to assess the status of Arizona healthcare systems' awareness and implementation of tobacco cessation and prevention measures. Methods The 20-item survey was developed by The University of Arizona HealthCare Partnership in collaboration with the Arizona Department of Health Services Bureau of Tobacco Education and Prevention. It was mailed to representatives of Arizona's 40 healthcare systems, including commercial and Medicare managed care organizations, "managed Medicaid" organizations, Veterans Affairs Health Care Systems, and Indian Health Service Medical Centers. Thirty-three healthcare systems (83% completed the survey. Results The majority of healthcare systems reported awareness of at least one tobacco cessation and prevention clinical practice guideline, but only one third reported full guideline implementation. While a majority covered some form of behavioral therapy, less than half reported covering tobacco treatment medications. "Managed Medicaid" organizations administered through the Arizona Health Care Cost Containment System were significantly less likely to offer coverage for behavioral therapy and less likely to cover pharmacotherapy than were their non-Medicaid counterparts in managed care, Veterans Affairs Health Care Systems and Indian Health Service Medical Centers. Conclusion Arizona healthcare system coverage for tobacco cessation in the year 2000 was comparable to national survey findings of the same year. The findings that only 10% of "Managed Medicaid" organizations covered tobacco treatment medication and were significantly less likely to cover behavioral therapy were important given the nearly double smoking prevalence among Medicaid patients. Throughout the years of the program, the strategic plan of the Arizona Department of Health Services Bureau of Tobacco

    2007-04-01

    Dispersed surface waves of regional events recorded at Network of Autonomously Recording Seismographs (NARS)-Baja and Red Sísmica de Banda Ancha (RESBAN) networks located over the Baja California Peninsula, Sonora, and Sinaloa, Mexico, were used to estimate shear wave elastic models and crustal thickness. We analyzed fundamental modes of surface waves with period between 10 and 40 s. Multiple filter analysis and the inversion method described by Herrmann and Ammon (2003) was used. Crustal thickness estimates for the Peninsular Ranges of Northern Baja California agree with those obtained by previous studies in the Peninsular Ranges of Northern Baja California. We analyzed dispersion of surface waves with northwest-southeast travel paths along the east and west sides of the Baja California Peninsula as well as a northwest-southeast travel path along the western sides of the Mexican states of Sonora and Sinaloa. It was found that the crustal structure east of the Baja California Peninsula is similar to the structure of Sonora and Sinaloa. The correlation between those two structures suggests dextral offset of the order of 275 ± 25 km if we consider Baja California Peninsula as a rigid body moving toward the northwest relative to the North America plate. This displacement between the structures is in agreement with the displacement determined by the dating of Miocene deposits located in San Felipe on the Baja California Peninsula (Pacific plate), and Isle Tiburon located west of Sonora (North America plate).

    In Nogales, Sonora, Mexico, some neighborhoods, or colonias, have intermittent delivery of water through pipes from the city of Nogales’s municipal water-delivery system while other areas lack piped water and rely on water delivered by truck or pipas. This research examined how lifestyles, water quality, and potential disease response, such as diarrhea, differs seasonally from a colonia with access to piped water as opposed to one using alternative water-delivery systems. Water samples were collected from taps or spigots at homes in two Nogales colonias. One colonia reflected high socio-environmental conditions where residents are supplied with municipal piped water (Colonia Lomas de Fatima); the second colonia reflected low socio-environmental conditions, lacking access to piped water and served by pipas (Colonia Luis Donaldo Colosio). A survey was developed and implemented to characterize perceptions of water quality, health impacts, and quality of life. Water samples were analyzed for microbial and inorganic water-quality parameters known to impact human health including, Escherichia coli (E. coli), total coliform bacteria, arsenic, and lead. A total of 21 households agreed to participate in the study (14 in Colosio and 7 in Fatima). In both colonias metal concentrations from water samples were all well below the United States Environmental Protection Agency’s (US EPA’s) maximum contaminant levels. E. coli concentrations exceeded the US EPA’s drinking-water standard in Colosio but not Fatima. Total coliform bacteria were present in over 50 % of households in both colonias. Microbial contamination was significantly higher in the summer than in the winter in both colonias. Resulting analysis suggests that residents in colonias without piped water are at a greater risk of gastrointestinal illness from consumption of compromised drinking water. Our survey corroborated reports of gastrointestinal illness in the summer months but not in the winter. Chloride

Todos foram submetidos ao teste de localização de fontes sonoras, no qual foram apresentados, aleatoriamente, três tipos de ondas quadradas, com frequências fundamentais em 0,5 kHz, 2 kHz e 4,5 kHz, na intensidade de 70 dBA. RESULTADOS: encontrou-se percentuais de acertos médios de 78,4%, 72,2% e 72,9% para os ouvintes normais, em 0,5 kHz, 2 kHz e 4,5 kHz, respectivamente e 40,1%, 39,4% e 41,7% para os usuários de aparelho de amplificação sonora individual. Quanto aos tipos de aparelhos, os usuários do modelo intracanal acertaram a origem da fonte sonora em 47,2% das vezes e os usuários do modelo retroauricular em 37,4% das vezes. Não foi observada correlação entre o percentual de acertos no teste de localização sonora e o tempo de uso da prótese auditiva. CONCLUSÃO: ouvintes normais localizam as fontes sonoras de maneira mais eficiente que os usuários de aparelho de amplificação sonora individual e, dentre estes, os que utilizam o modelo intracanal obtiveram melhor desempenho. Além disso, o tempo de uso não interferiu no desempenho para localizar a origem das fontes sonoras.PURPOSE: to compare the sound localization performance of hearing aids users, with the performance of normal hearing in the horizontal and sagittal planes, at 0.5, 2 and 4

    The University of Arizona Astronomy Club creates a unique environment for undergraduates to accomplish goals early in their academic career. The club provides research opportunities with advisors, graduate students, and projects organized by fellow undergraduates. Undergraduates that work side-by-side develop strong working relationships which keeps students interested in astronomy and enables them to thrive in their studies and research. Club members are encouraged to attend and present their research at professional conferences where they are exposed early to the scientific research community, learn about internship and REU opportunities, and get information about graduate programs. In addition to preparing undergraduates to thrive in their academic career, the club also offers outreach opportunities for members to actively educate the southern Arizona community. Members of the club design and create many of their outreach materials including 3D models of our local stellar neighborhood and astronomical objects. Astronomy Club has had a positive impact on its members, the Department of Astronomy, and the southern Arizona community for the past seven years. The club continues to strive to improve undergraduate retention and prepare students for their future careers.

    2010-01-01

    Full Text Available Después de valorar la creciente importancia de la industrialización en Sonora, en este trabajo se investiga si durante 1993-2003 sus municipios tendieron hacia una mayor o menor diferenciación de su valor agregado manufacturero, y si dicho patrón ha estado condicionado por los criterios de asignación geográfica de la inversión estatal en infraestructura. Con esto último, se revisan las políticas estatales que, en teoría, deberían funcionar como contrapeso de las disparidades intermunicipales. Se concluye que aunque los ritmos de convergencia intermunicipal en Sonora son relativamente altos éstos han tendido a declinar. Además, se confirma la limitada capacidad del estado para incidir con sus propios recursos sobre el patrón regional de desarrollo manufacturero prevaleciente.

    2015-02-01

    Rocky Mountain spotted fever (RMSF) is an increasingly important cause of preventable mortality in children in Sonora, Mexico. Although early treatment with tetracycline has shown to prevent fatal outcome, the disease remains a life-threatening condition, particularly for children. This study describes the clinical factors associated with pediatric mortality due to RMSF in Sonora, in order to guide healthcare practices. This is a retrospective analysis of 104 children consecutively hospitalized at the major pediatric hospital of Sonora, diagnosed with RMSF between January 2004 and December 2013. Descriptive statistics and multiple logistic regression were used to identify risk factors for fatal outcome. The case fatality ratio in this cohort was 20.2%. Children were hospitalized after a median of 6 days from onset of symptoms including fever (100%), rash involving palms and soles (88.5%) and headache (79.8%); 90.4% of fatal cases had low platelet counts (<50,000/μL) and 33.3% showed serum creatinine concentrations above the normal value. Acute kidney injury increased mortality, odds ratio (OR(adj)) = 4.84, 95% confidence interval (CI): 1.2-16.2, as well as delay in treatment (≥ 5th day from onset) with doxycycline, OR(adj) = 2.62, 95% CI: 1.24-5.52 and hemorrhage, OR(adj) = 6.11, 95% CI: 1.89-19.69. RMSF is a public health problem in Sonora. Clinically, fatal cases differ from non-fatal cases in renal function and hemorrhagic manifestations, although these findings may occur too late for a timely intervention. First-line providers must be educated to harbor a timely suspicion of RMSF, and should provide empiric treatment with doxycycline when febrile patients first present for care.

    En el estado de Sonora la población china enfrentó una manifiesta discriminación expresada en la Ley 31 de 1923. Esta Ley prohibía el matrimonio y la mestización entre hombres chinos y mujeres mexicanas. Por medio de peticiones de amparo, parejas mexicano-chinas desafiaron esta legislación, llegando con los procesos legales hasta la Suprema Corte de Justicia. En los años 1924 y 1925, jueces federales en Sonora aplicaron los principios de la Constitución y de la legislación federal para proteger a la población china. Las peticiones de amparo demuestran tanto los desafíos como las posibilidades que el derecho otorgó a los residentes de México en las primeras décadas del siglo XX.

    Full Text Available Tellurium production is limited mainly to that obtained from the treatment of electrolyte muds from copper refineries. However, there are several other sources from which the precious metal tellurides are potentially attractive. This work presents a review of the main localities in Sonora (México, where tellurides have been found. In addition, based upon the physical chemistry fundamentals for tellurium and precious metal tellurides, the aqueous extraction and recovery routes are discussed.

    El teluro es un elemento escaso, pero con un espectro amplio de aplicaciones. Su producción está limitada a la obtenida por el tratamiento de los lodos electrolíticos de las refinerías de cobre. De las fuentes alternativas de teluro, los telururos de metales preciosos son atractivos por la asociación natural de estos dos elementos, con la posibilidad de obtener el teluro como subproducto. Sonora (México, se caracteriza por ser una zona rica en teluros con más de treinta especies registradas. Este artículo describe las principales localizaciones en que se encuentran minerales de teluro en Sonora (México, señalando sus principales características, así como las especies hasta ahora registradas. Se analizan, además, las posibles rutas de extracción y recuperación acuosa de teluro, de acuerdo con la fisicoquímica de los sistemas teluro-metales preciosos.

    Full Text Available Tres acontecimientos fundamentales marcaron la historia de Sonora durante el periodo comprendido entre la guerra de 1848 y la primera década del siglo XX. El primero fue la construcción del ferrocarril por norte americanos dentro de territorio mexicano. El segundo, y en gran parte consecuencia de los lazos que creó el ferrocarril, fue el florecimiento de la minería de metales industriales, en particular el cobre, y con ella la creciente presencia y finalmente predominio de los mercados y el capital estadounidenses dentro del estado. Si bien esta apertura hacia lo norteamericano finalmente transformó a Sonora en uno de los estados más ricos de México, también selló su dependencia con el país del norte. Por último, debido a la creciente importancia de los mercados e inversiones norteamericanos, se implantó un patrón de crecimiento económico en Sonora que, al favorecer las zonas ligadas a Estados Unidos, fomentó su crecimiento a expensas de otras. Este ensayo cuenta una parte de esa historia.

    2009-12-01

    Full Text Available The continuous education, that the productive sector demands, is not only the accumulation of new knowledge, supported inthe education-learning process, but also a focus on the new tendencies that the labor field demands, where the universities havethe opportunity to extend their involvement, through graduations or specializations, that contribute the strength of the acquiredskills in the classroom. The objective is to know the kind of graduation interests that motivate the graduates, as a process ofcontinuous education. The study is based on the application of a questionnaire to 50 students of different degrees from publicuniversities in Sonora, whose excellent results are: 51% of those surveyed, indicate that at the end of their degree they do notobtain the tools to compete in their labor field. 92% of the students mention that universities should offer within the educativeprogram some area of financial or specialization, related to other disciplines. Another important data is that the financial areasthat graduates prefer are related to the social administrative and financial areas and in smaller proportion they prefer the engineeringdisciplines. 70% of those surveyed, indicate that universities have infrastructure, learning spaces and the skilled humanresources to offer this type of courses. The conclusion of this work, is that public universities follow training programs related tocertain areas and disciplines, centered on the student and learning, like part of their formation, but they do not have the educativeflexibility and the graduates will need to know other disciplines to complement their professional education.

  14. Presymptomatic Parkinson's disease: the Arizona experience.

    Caviness, John N

    2012-01-01

    There is a growing interest in presymptomatic diagnosis of Parkinson's disease (PD), but the best and most practical method to screen and confirm asymptomatic individuals for PD needs further study. The Banner-Sun Health Brain and Body Donation program in Sun City, Arizona has studied primarily PD and Alzheimer's disease. Enrollees receive annual prospective standardized evaluation that includes clinical, biomarker testing, and at autopsy, neuropathological examination is performed followed by a consensus conference that determines final diagnosis. Since numerous Controls receive these assessments, these subjects become an excellent cohort to study presymptomatic PD. We found that Controls with partial diagnostic criteria for PD (1 of either rest tremor or bradykinesia) had a 6.6 relative risk for eventually developing full diagnostic criteria for PD. Neuropathologic examination has uncovered cases of "incidental Lewy body disease" (ILBD). We have shown that ILBD cases during life demonstrated no significant differences in clinical assessment versus similarly assessed controls. However, electrophysiological assessment showed subclinical low frequency rest discharges in some ILBD cases. Electroencephalography spectral frequency of ILBD cases was lower than for controls but not as low as for PD cases. The longitudinal assessments of this brain bank offer significant opportunities for the study of presymptomatic PD. Copyright © 2011 Elsevier Ltd. All rights reserved.

  20. Significance of detrital zircons in upper Devonian ocean-basin strata of the Sonora allochthon and Lower Permian synorogenic strata of the Mina Mexico foredeep, central Sonora, Mexico

    Science.gov (United States)

    Poole, F.G.; Gehrels, G.E.; Stewart, John H.

    2008-01-01

    U-Pb isotopic dating of detrital zircons from a conglomeratic barite sandstone in the Sonora allochthon and a calciclastic sandstone in the Mina Mexico foredeep of the Minas de Barita area reveals two main age groups in the Upper Devonian part of the Los Pozos Formation, 1.73-1.65 Ga and 1.44-1.42 Ga; and three main age groups in the Lower Permian part of the Mina Mexico Formation, 1.93-1.91 Ga, 1.45-1.42 Ga, and 1.1-1.0 Ga. Small numbers of zircons with ages of 2.72-2.65 Ga, 1.30-1.24 Ga, ca. 2.46 Ga, ca. 1.83 Ga, and ca. 0.53 Ga are also present in the Los Pozos sandstone. Detrital zircons ranging in age from 1.73 to 1.65 Ga are considered to have been derived from the Yavapai, Mojave, and Mazatzal Provinces and their transition zones of the southwestern United States and northwestern Mexico. The 1.45-1.30 Ga detrital zircons were probably derived from scattered granite bodies within the Mojave and Mazatzal basement rocks in the southwestern United States and northwestern Mexico, and possibly from the Southern and Eastern Granite-Rhyolite Provinces of the southern United States. The 1.24-1.0 Ga detrital zircons are believed to have been derived from the Grenville (Llano) Province to the east and northeast or from Grenvilleage intrusions or anatectites to the north. Several detrital zircon ages ranging from 2.72 to 1.91 Ga were probably derived originally from the Archean Wyoming Province and Early Paleoproterozoic rocks of the Lake Superior region. These older detrital zircons most likely have been recycled one or more times into the Paleozoic sandstones of central Sonora. The 0.53 Ga zircon is believed to have been derived from a Lower Cambrian granitoid or meta-morphic rock northeast of central Sonora, possibly in New Mexico and Colorado, or Oklahoma. Detrital zircon geochronology suggests that most of the detritus in both samples was derived from Laurentia to the north, whereas some detritus in the Permian synorogenic foredeep sequence was derived from the

    The Arizona Source Phenomenology Experiments (SPE) have resulted in an important dataset for the nuclear monitoring community. The 19 dedicated single-fired explosions and multiple delay-fired mining explosions were recorded by one of the most densely instrumented accelerometer and seismometer arrays ever fielded, and the data have already proven useful in quantifying confinement and excitation effects for the sources. It is very interesting to note that we have observed differences in the phenomenology of these two series of explosions resulting from the differences between the relatively slow (limestone) and fast (granodiorite) media. We observed differences at the two SPE sites in the way the rock failed during the explosions, how the S-waves were generated, and the amplitude behavior as a function of confinement. Our consortium's goal is to use the synergy of the multiple datasets collected during this experiment to unravel the phenomenological differences between the two emplacement media. The data suggest that the main difference between single-fired chemical and delay-fired mining explosion seismograms at regional distances is the increased surface wave energy for the latter source type. The effect of the delay-firing is to decrease the high-frequency P-wave amplitudes while increasing the surface wave energy because of the longer source duration and spall components. The results suggest that the single-fired explosions are surrogates for nuclear explosions in higher frequency bands (e.g., 6-8 Hz Pg/Lg discriminants). We have shown that the SPE shots, together with the mining explosions, are efficient sources of S-wave energy, and our next research stage is to postulate the possible sources contributing to the shear-wave energy.

    We present a series of four pregnant women with Rocky Mountain spotted fever (RMSF) that occurred in Sonora, Mexico, during 2015-2016. Confirmatory diagnoses were made by polymerase chain reaction or serological reactivity to antigens of Rickettsia rickettsii by using an indirect immunofluorescence antibody assay. Each patient presented with fever and petechial rash and was treated successfully with doxycycline. Each of the women and one full-term infant delivered at 36 weeks gestation survived the infection. Three of the patients in their first trimester of pregnancy suffered spontaneous abortions. RMSF should be suspected in any pregnant woman presenting with fever, malaise and rash in regions where R. rickettsii is endemic.

    Ibervillea sonorae's root, or "wareque" (Cucurbitaceae), is widely used in Mexican traditional medicine for the control of diabetes mellitus. In the present study, the hypoglycemic effects produced by the acute and chronic administration of various extracts of Ibervillea sonorae were investigated. Both the traditional preparation (aqueous decoction) and the raw extract (juice) from the root resulted in significant reductions of glycemia in healthy mice after intraperitoneal administration at a dose of 600 mg/kg. Additionally, ground dried root was used to obtain a dichloromethane (DCM) extract and a methanol (MeOH) extract. The DCM extract induced a clear reduction of glycemia in healthy (P < 0.05) and in alloxan-diabetic mice. The intraperitoneally administered DCM extract caused a severe hypoglycemia that produced lethality in all the treated animals when doses of 300 and 600 mg/kg body weight were used. Since the DCM extract showed a marked hypoglycemic activity, it was administered daily per os to alloxan diabetic rats, employing corn oil and tolbutamide as controls. After 41 days of DCM extract administration at a dose of 300 mg/kg/day, diabetic rats showed improvement in glycemia, body weight, triglycerides, and GPT in comparison with the diabetic control group. Total cholesterol, GOT, and uric acid blood levels were not affected.

    2007-01-01

    Despite the occurrence of Neoproterozoic strata throughout the southwestern U.S. and Sonora, Mexico, glacial units overlain by enigmatic cap carbonates have not been well-documented south of Death Valley, California. Here, we describe in detail the first glaciogenic diamictite and cap carbonate succession from Mexico, found in the Cerro Las Bolas Group. The diamictite is exposed near Sahuaripa, Sonora, and is overlain by a 5 m thick very finely-laminated dolostone with soft sediment folds. Carbon isotopic chemostratigraphy of the finely-laminated dolostone reveals a negative δ13C anomaly (down to − 3.2‰ PDB) characteristic of cap carbonates worldwide. Carbon isotopic values rise to + 10‰ across ∼ 400 m of section in overlying carbonates of the Mina el Mezquite and Monteso Formations. The pattern recorded here is mostly characteristic of post-Sturtian (ca. ≤ 700 Ma), but pre-Marinoan (ca. ≥ 635 Ma) time. However, the Cerro Las Bolas Group shares ambiguity common to most Neoproterozoic successions: it lacks useful radiometric age constraints and biostratigraphically useful fossils, and its δ13C signature is oscillatory and therefore somewhat equivocal.

  2. Reevaluation of the macroseismic effects of the 1887 Sonora, Mexico earthquake and its magnitude estimation

    2008-01-01

    The Sonora, Mexico, earthquake of 3 May 1887 occurred a few years before the start of the instrumental era in seismology. We revisit all available accounts of the earthquake and assign Modified Mercalli Intensities (MMI), interpreting and analyzing macroseismic information using the best available modern methods. We find that earlier intensity assignments for this important earthquake were unjustifiably high in many cases. High intensity values were assigned based on accounts of rock falls, soil failure or changes in the water table, which are now known to be very poor indicators of shaking severity and intensity. Nonetheless, reliable accounts reveal that light damage (intensity VI) occurred at distances of up to ~200 km in both Mexico and the United States. The resulting set of 98 reevaluated intensity values is used to draw an isoseismal map of this event. Using the attenuation relation proposed by Bakun (2006b), we estimate an optimal moment magnitude of Mw7.6. Assuming this magnitude is correct, a fact supported independently by documented rupture parameters assuming standard scaling relations, our results support the conclusion that northern Sonora as well as the Basin and Range province are characterized by lower attenuation of intensities than California. However, this appears to be at odds with recent results that Lg attenuation in the Basin and Range province is comparable to that in California.

    Full Text Available In order to increase knowledge about the vegetative structure and environmental conditions, two coastal areas (north and south in Sonora, Mexico, where Salicornia bigelovii develops in natural form were investigated. Based on the abundance of Salicornia, three locations were selected in the two areas. Transects in each of the three sites were developed. The sediments in the northern areas showed higher values compared with the south areas of Sonora in organic matter. Plant biomass, density, height and frequency of occurrence were higher in frequently flooded areas compared to sparsely or less often by the tides. The average total biomass ranged from 2.23 to 6.33 kg (dry weight m-2 and is composed primarily of surface components. The maximum values of biomass of Salicornia were observed in February to May in both areas. The growth of Salicornia bigelovii is influenced mainly by the frequency of flooding, duration of exposure to air during low tide, rainfall, salinity and salt content of the ambient water and sediment, respectively. The carbon content increased with plant age, while protein content decreased by 233.6%. The steady increase in human pressure on coastal areas where Salicornia and other halophytes growth, require immediate protection order to prevent vulnerabilities in their populations.

    Full Text Available In the southeast of Sonora as in most of the State, land is unproductive due to its arid and semi-arid land, if it does not have small or large irrigation facilities. Where economic conditions are reduced, producers need to develop techniques that help to overcome the erraticity in the availability of water, especially for irrigation. That's why Mays Indian and Masiaca community private producers from Sonora have developed a technique for harvesting from water of avenues of the intermittent streams near their plots, and once the ground has the adequate humidity conditions they can establish crops of their interest, so it is possible to obtain acceptable harvest in corn, peas, sorghum and safflower. However, these producers face a series of problems related primarily to the lack of rain; lack of credit support for the construction or maintenance of the required facilities; lack of profitability of crops established there, the abandonment of agricultural land, erosion of knowledge, etc. The analysis of this study can draw the following conclusions: The bagging technique is feasible if there are heavy rains, with the presence of cyclones, in October; the acceptable harvest obtained in established crops is largely due to the contribution of organic matter derived from the Avenues; the organizational levels observed are simple and operational.

    2011-01-01

    Obesity, type II diabetes, and hyperlipidaemia, which frequently coexist and are strongly associated with oxidative stress, increase the risk of cardiovascular disease. An increase in carbohydrate intake, especially of fructose, and a high-fat diet are both factors that contribute to the development of these metabolic disorders. In recent studies carried out in diabetic rats, authors reported that Ibervillea sonorae had hypoglycaemic activity; saponins and monoglycerides present in the plant could be responsible for the effects observed. In the present study, we determined the effects of an aqueous I. sonorae extract on a murine model of obesity and hyperglycaemia, induced by a high-calorie diet, and the relationship of these effects with hepatic oxidation. A high-fat diet over a period of 8 weeks induced weight gain in the mice and increased triglycerides and blood glucose levels. Simultaneous treatment with I. sonorae aqueous extracts, at doses of 100, 200, and 400 mg/kg, decreased triglycerides and glycaemia levels, prevented an increase in body weight in a dose-dependent manner, and decreased hepatic lipid oxidation at a dose of 200 mg/kg. These data suggest that the aqueous extract from I. sonorae root prevents obesity, dyslipidaemia, and hyperglycaemia induced by a hypercaloric diet; however, high doses may induce toxicity.

    The Mogollon Highlands, 4,855 square miles of rugged, mountainous terrain at the southern edge of the Colorado Plateau in central Arizona, is characterized by a bedrock-dominated hydrologic system that results in an incompletely integrated regional ground-water system, flashy streamflow, and various local water-bearing zones that are sensitive to drought. Increased demand on the water resources of the area as a result of recreational activities and population growth have made necessary an increased understanding of the hydrogeology of the region. The U.S. Geological Survey conducted a study of the geology and hydrology of the region in cooperation with the Arizona Department of Water Resources under the auspices of the Arizona Rural Watershed Initiative, a program launched in 1998 to assist rural areas in dealing with water-resources issues. The study involved the analysis of geologic maps, surface-water and ground-water flow, and water and rock chemical data and spatial relationships to characterize the hydrogeologic framework. The study area includes the southwestern corner of the Colorado Plateau and the Mogollon Rim, which is the eroded edge of the plateau. A 3,000- to 4,000-foot sequence of early to late Paleozoic sedimentary rocks forms the generally south-facing scarp of the Mogollon Rim. The area adjacent to the edge of the Mogollon Rim is an erosional landscape of rolling, step-like terrain exposing Proterozoic metamorphic and granitic rocks. Farther south, the Sierra Ancha and Mazatzal Mountain ranges, which are composed of various Proterozoic rocks, flank an alluvial basin filled with late Cenozoic sediments and volcanic flows. Eight streams with perennial to intermittent to ephemeral flow drain upland regions of the Mogollon Rim and flow into the Salt River on the southern boundary or the Verde River on the western boundary. Ground-water flow paths generally are controlled by large-scale fracture systems or by karst features in carbonate rocks. Stream

    Although the number of ecosystem service modeling tools has grown in recent years, quantitative comparative studies of these tools have been lacking. In this study, we applied two leading open-source, spatially explicit ecosystem services modeling tools – Artificial Intelligence for Ecosystem Services (ARIES) and Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) – to the San Pedro River watershed in southeast Arizona, USA, and northern Sonora, Mexico. We modeled locally important services that both modeling systems could address – carbon, water, and scenic viewsheds. We then applied managerially relevant scenarios for urban growth and mesquite management to quantify ecosystem service changes. InVEST and ARIES use different modeling approaches and ecosystem services metrics; for carbon, metrics were more similar and results were more easily comparable than for viewsheds or water. However, findings demonstrate similar gains and losses of ecosystem services and conclusions when comparing effects across our scenarios. Results were more closely aligned for landscape-scale urban-growth scenarios and more divergent for a site-scale mesquite-management scenario. Follow-up studies, including testing in different geographic contexts, can improve our understanding of the strengths and weaknesses of these and other ecosystem services modeling tools as they move closer to readiness for supporting day-to-day resource management.

    Arizona Western College, Yuma, Arizona, serves the largely Hispanic population of rural southwestern Arizona. The majority of our students are first-generation college students who frequently lack strong educational role models. We are constructing a geoscience education program for recruiting and mentoring Hispanic and Native American students from Yuma and La Paz counties, Arizona. This program will be structured around faculty-mentored, undergraduate research on the seismicity and related geologic phenomenon of the Salton Trough of southeastern California and northern Mexico. Yuma-area students are well-suited for this program, because they have strong footholds in the cultures and languages of the region. Our chief goal is to provide educational opportunities in geoscience for historically underrepresented minorities of southern Arizona and California. Ultimately, this should lead to leadership roles in the geoscience for Hispanics in the largely Hispanic communities of the desert southwest. Importantly, this geoscience education program has the support and collaboration of science educators from across the educational spectrum in southern Arizona and California, and northern Mexico.

    Studies that integrate human dimensions and the biophysical characteristics of watersheds are necessary to meet the challenge of sustainable water resources development. In this project, we integrated perspectives from sociology, hydrology, and environmental engineering to examine and suggest solutions for managing waterborne disease risks associated with wastewater contamination in the Sonora River basin (SRB), a semiarid rural basin in northwest Mexico. This research consisted of four sub-projects. First, we assessed the perceptions of risks associated with wastewater contamination of water resources in rural communities in the SRB through a series of semi-structured interviews Results from this study indicate that there are major differences in risk perceptions among health professionals, government officials, and lay citizens. Government officials and lay citizens tend to underestimate the severity of the problems related to water related risks. Second, a fully distributed hydrologic model was used to make streamflow predictions in the un-gauged SRB. Synthetic flows generated from the hydrologic model were used to evaluate pollutant transport processes associated with wastewater loadings to the Sonora River. The hydrologic model revealed that the high degree of spatio-temporal variability of runoff in the SRB is associated with links between runoff generation mechanisms and land-atmosphere interactions. Third, a surface water quality model was used to assess the impact of wastewater discharges and develop pathogen contamination indicators in two sites along the Sonora River. To parameterize the water quality model, pathogenic indicator loadings and removal rates were estimated, along with their uncertainty. Results from the water quality modeling show regions in the watershed that may be exceeding pathogenic standards, but also that uncertainty in model parameters requires a probabilistic approach for estimating risks. Finally, a workshop was conducted to

    The Central Arizona Basins study area in central and southern Arizona and northern Mexico is one of 60 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment program. The purpose of this report is to describe the physical, chemical, and environmental characteristics that may affect water quality in the Central Arizona Basins study area and present an overview of water quality. Covering 34,700 square miles, the study area is characterized by generally north to northwestward-trending mountain ranges separated by broad, gently sloping alluvial valleys. Most of the perennial rivers and streams are in the northern part of the study area. Rivers and streams in the south are predominantly intermittent or ephemeral and flow in response to precipitation such as summer thunderstorms. Effluent-dependent streams do provide perennial flow in some reaches. The major aquifers in the study area are in the basin-fill deposits that may be as much as 12,000 feet thick. The 1990 population in the study area was about 3.45 million, and about 61 percent of the total was in Maricopa County (Phoenix and surrounding cities). Extensive population growth over the past decade has resulted in a twofold increase in urban land areas and increased municipal water use; however, agriculture remains the major water use. Seventy-three percent of all water with drawn in the study area during 1990 was used for agricultural purposes. The largest rivers in the study area-the Gila, Salt, and Verde-are perennial near their headwaters but become intermittent downstream because of impoundments and artificial diversions. As a result, the Central Arizona Basins study area is unique compared to less arid basins because the mean surface-water outflow is only 528 cubic feet per second from a total drainage area of 49,650 square miles. Peak flows in the northern part of the study area are the result of snowmelt runoff; whereas, summer thunderstorms account for the peak flows in

    The aim of this work is to analyze the spatial distribution of potential pollution pathways of water resources given the economic activity in the Mexican border state of Sonora and propose a regional distribution in relation to cancer mortality rates across the state. The methodology is based in an exploratory and inferential data analysis using two sources of primary data: wastewater discharge concessions registered in the Public Registry on Water Rights [Registro Público de Derechos de Agua] (REPDA) and the records generated by the National Health Information System [Sistema Nacional de Información en Salud] (SINAIS) in the period 1998-2011 based on the International Classification of Disease (ICD-10). The spatial concentration analysis allows for the identification of specific cancer mortality causes at the regional level. Results indicate that the projected adjustments to the regulation NOM-250-SSA1-2014, which controls a subset of pollutants common in mining activity surroundings, is a matter of regional concern.

    Eleven monoglycerides (MG), 1-monopalmitin (1), glyceryl 1-monomargarate (2), 1-monostearin (3), glyceryl 1-monononadecylate ( 4), glyceryl 1-monoarachidate (5), glyceryl 1-monobehenate (6), glyceryl 1-monotricosanoate (7), glyceryl 1-monotetracosanoate (8), glyceryl 1-monopentacosanoate (9), glyceryl 1-monohexacosanoate (10) and glyceryl 1-monooctacosanoate (11), together with five fatty acids (FA), lauric acid (12), myristic acid (13), pentadecanoic acid (14), palmitic acid (15) and stearic acid (16) were isolated of the root of IBERVILLEA SONORAE Greene (Cucurbitaceae). Their structures were determined by spectroscopic and chemical methods as well as GC-MS analysis. The hypoglycemic activity of the dichloromethane (DCM) extract, of fractions (F1-F10 and SF1-SF5), of monoglycerides (MG) and of fatty acids (FA) mixtures obtained of the root from I. SONORAE was evaluated in normoglycemic and alloxan-induced diabetic mice. The results showed that by intraperitoneal administration the DCM extract (300 mg/kg), F9 (300 mg/kg) and SF1 (150 mg/kg) significantly reduced glucose levels in both models. For fraction SF1, the hypoglycemic activity was more pronounced than that of tolbutamide (150 mg/kg) used as control. However, neither MG (75 mg/kg) nor FA (75 mg/kg) mixtures isolated from SF1 exhibited a significant hypoglycemic effect. However, when MG and FA were combined in equal proportions (75 mg: 75 mg/kg), their effect was comparable to that of SF1. The observed activity for the DCM extract, F9, SF1 and the MG-FA mixture provides additional support for the popular use of this plant in the treatment of diabetes mellitus in Mexican traditional medicine.

    Full Text Available La política ambiental en México ya es parte de la agenda de seguridad nacional, sin embargo, uno de sus instrumentos de planeación clave es el OET (Ordenamiento Ecológico del Territorio, el cual no ha logrado el impacto previsto. Se propone a los pueblos y territorios indígenas de Sonora como sector estratégico para la implementación de los OET, para lo cual se considera necesario profundizar en su problemática actual. Por ello, se realiza un análisis socioambiental de los complejos bioculturales de Sonora, a partir del marco de reflexión de la ecología política y la perspectiva biocultural. Esto se logra a partir de un análisis interdisciplinario donde se conjugan epistemologías y metodologías de los campos de las ciencias sociales y de la ecología. El análisis socioambiental se organiza a partir de dos grandes temas: la territorialidad y la comunidad indígena contemporánea. Se concluye que el formato actual de los OET es poco operativo, por lo que se dan recomendaciones para eficientar su implementación. Por último, se resalta la importancia de la atención de los complejos bioculturales, en primera instancia como un tema de justicia ambiental, así como por su capacidad para incidir a favor de los temas globales ambientales, como el cambio climático y la disponibilidad y calidad del agua.

Debido a que los adultos mayores constituyen el grupo etario con mayor prevalencia de enfermedades crónico-degenerativas, la polifarmacia es un fenómeno común en poblaciones geriátricas. No se conoce con precisión cuál es la prevalencia en un grupo de ancianos asilados del estado de Sonora. Se realizó un estudio transversal, para estimar la prevalencia de polifarmacia en una muestra no probabilística de adultos mayores residentes de asilos de ancianos de Hermosillo, Sonora. La prevalencia de polifarmacia (definida como consumo concomitante de 4 o más fármacos fue de 36.1%, sin diferencias significativas respecto al tipo de enfermedades crónicas padecidas, así como a la edad y sexo de los ancianos asilados. Los sujetos con polifarmacia tuvieron un exceso de riesgo, superior a 10 veces, cuando la prescripción farmacológica era realizada por más de un médico, y tuvieron 5 veces más probabilidad de presentar algún efecto adverso a medicamentos respecto a los sujetos con ausencia de polifarmacia. La polifarmacia es un fenómeno que requiere mayor atención, control e investigación futura, toda vez que los adultos mayores son el grupo poblacional con mayor tendencia de crecimiento en México.

    Boiled down to its essentials, the grant’s purpose was to develop and demonstrate the viability of compressed air energy storage (CAES) for use in renewable energy development. While everyone agrees that energy storage is the key component to enable widespread adoption of renewable energy sources, the development of a viable scalable technology has been missing. The Department of Energy has focused on expanded battery research and improved forecasting, and the utilities have deployed renewable energy resources only to the extent of satisfying Renewable Portfolio Standards. The lack of dispatchability of solar and wind-based electricity generation has drastically increased the cost of operation with these components. It is now clear that energy storage coupled with accurate solar and wind forecasting make up the only combination that can succeed in dispatchable renewable energy resources. Conventional batteries scale linearly in size, so the price becomes a barrier for large systems. Flow batteries scale sub-linearly and promise to be useful if their performance can be shown to provide sufficient support for solar and wind-base electricity generation resources. Compressed air energy storage provides the most desirable answer in terms of scalability and performance in all areas except efficiency. With the support of the DOE, Tucson Electric Power and Science Foundation Arizona, the Arizona Research Institute for Solar Energy (AzRISE) at the University of Arizona has had the opportunity to investigate CAES as a potential energy storage resource.

    2010-01-01

    During the course of field work in Cabeza Prieta National Wildlife Refuge, southwestern Arizona, in 2003, James Cain and Brian Jansen collected Salvia vaseyi, previously known only from the western edge of the Sonoran Desert in California and Baja California. Our findings indicate this shrub might be more widespread in southwestern Arizona mountains. Salvia vaseyi in Arizona seems to represent a relict population. There are other shrubby Salvia in Arizona, but S. vaseyi is the most xeric-mhabiting species and has the narrowest ecological and geographical range.

    Full Text Available This research evaluates the impact of tutorship in academic achievement in the Institute. A data of 1812 first semester students who took tutorship were analyzed. It was found that gender, tutorship and GPA in high school is significantly related with academic success. Results of logistic regression indicate that the odds for a student who has tutorship fails is less than a half for a student of the same gender without tutorship. This model indicates also that a difference of one point in GPA in high school has more influence in student success that tutorship.

    2011-01-01

    Full Text Available La formación de cadenas productivas es una condición indispensable para el desarrollo económico local en el nuevo escenario que genera un entorno globalmente competitivo. En el caso de Sonora, a partir de la instalación de la planta de estampado y ensamble de la Ford Motor Company en Hermosillo en 1986, las empresas locales no han podido integrarse plenamente a los procesos productivos de la planta. Este fracaso tiene su principal origen en la inadecuada política industrial aplicada por los organismos gubernamentales y privados, junto con la falta de una cultura emprendedora que asuma mayores riesgos. En este artículo se presenta la historia de la industria automotriz en México, en especial el caso de Sonora. Los resultados permiten prever que difícilmente -en el corto plazo- se generarán encadenamientos productivos.

  14. Imaginación histórica, forma y experiencia estética en las instalaciones sonoras

    Directory of Open Access Journals (Sweden)

    Daniel Halaban

    2017-03-01

    Full Text Available En este trabajo se indaga sobre el problema de la forma en un tipo específico de instalaciones sonoras y su implicancia política. Se considera que una concepción historizada de la imaginación permite desgarrar el continuum destemporalizado e indeterminado de esos dispositivos artísticos y reconstruir las relaciones materiales allí cifradas. Para esto se propone articular el análisis empírico de algunas instalaciones sonoras con un recorrido teórico. En este último se discute la lectura de Jacques Rancière sobre políticas estéticas para centrar el debate sobre el arte sublime lyotardiano y la tensión con la propuesta adorniana. El arte sublime, para François Lyotard, es aquel que posibilita el desborde de la razón por la experiencia sensible y se caracteriza por ser "pura diferencia", una "materia inmaterial" indeterminada –en música esto se encuentra en el timbre. Se sostiene, sin embargo, que los experimentos de Pierre Schaeffer indican que en la contemporaneidad no es posible una experiencia tal. La propuesta del artículo es que se puede recuperar el pensamiento formal en las instalaciones sonoras como la síntesis que opera la razón de los fragmentos producidos por la imaginación historizada que penetra al interior de aquello "indeterminado".

    Full Text Available Subsurface sediments of the Sonora Margin (Guaymas Basin, located in proximity of active cold seep sites were explored. The taxonomic and functional diversity of bacterial and archaeal communities were investigated from 1 to 10 meters below the seafloor. Microbial community structure and abundance and distribution of dominant populations were assessed using complementary molecular approaches (Ribosomal Intergenic Spacer Analysis, 16S rRNA libraries and quantitative PCR with an extensive primers set and correlated to comprehensive geochemical data. Moreover the metabolic potentials and functional traits of the microbial community were also identified using the GeoChip functional gene microarray and metabolic rates. The active microbial community structure in the Sonora Margin sediments was related to deep subsurface ecosystems (Marine Benthic Groups B and D, Miscellaneous Crenarchaeotal Group, Chloroflexi and Candidate divisions and remained relatively similar throughout the sediment section, despite defined biogeochemical gradients. However, relative abundances of bacterial and archaeal dominant lineages were significantly correlated with organic carbon quantity and origin. Consistently, metabolic pathways for the degradation and assimilation of this organic carbon as well as genetic potentials for the transformation of detrital organic matters, hydrocarbons and recalcitrant substrates were detected, suggesting that chemoorganotrophic microorganisms may dominate the microbial community of the Sonora Margin subsurface sediments.

    2016-01-01

    The Sonoran Tiger Salamander (Ambystoma mavortium stebbinsi Lowe, 1954) was listed as federally endangered in the USA in 1997 (USFWS 1997). In the USA, the distribution of A. mavortium stebbinsi is limited to the San Rafael Valley (approximately 567 km2), between the Sierra San Antonio (called the Patagonia Mountains in Arizona) and Huachuca Mountains, and south of the Canelo Hills, Arizona (Fig. 1). The USA listing was triggered by loss of natural wetland habitats, threats from invasive predators, frequent die-offs from disease, introgression with the introduced Barred Tiger Salamander (A. mavortium mavortium), and small range and number of breeding sites that increases susceptibility to stochastic events (USFWS 1997). Small population sizes and limited gene flow have caused inbreeding, which may further reduce population viability and the potential for recovery (Jones et al. 1988; Storfer et al. 2014).

  11. U-Pb zircon and Re-Os molybdenite geochronology from La Caridad porphyry copper deposit: insights for the duration of magmatism and mineralization in the Nacozari District, Sonora, Mexico

    Valencia, V. A.; Ruiz, J.; Barra, F.; Geherls, G.; Ducea, M.; Titley, S. R.; Ochoa-Landin, L.

    2005-03-01

    Uranium-lead zircon (laser ablation multi-collector ICP-MS spot analysis) ages from La Caridad porphyry copper deposit in the Nacozari District, Northeastern Sonora, Mexico, suggest a short period of magmatism, between 55.5 and 52.6 Ma. Two U-Pb ages from the mineralized quartz monzonite unit, showing different textural characteristics, yielded indistinguishable crystallization ages (~54 Ma), and indicate that the intrusion responsible for the mineralization occurred as a single large complex unit, instead of multiple pulses of magmatism. Some zircons analyzed also show inherited ages in cores recording dates of 112-124 Ma, 141-166 Ma and 1.4 Ga. The Re-Os molybdenite ages from the potassic and phyllic hydrothermal alteration veins yielded identical ages within error, 53.6±0.3 Ma and 53.8±0.3 Ma, respectively (weighted average of 53.7±0.21 Ma), supporting a restricted period for the mineralization. The geochronological data thus indicate a short-lived magmatic and hydrothermal system. The inherited zircons of Precambrian and Late Jurassic-Mid Cretaceous age found in the intrusive rocks of La Caridad deposit, can be explained considering two possible scenarios within the tectonic/magmatic evolution of the area. The first scenario considers the presence of a Precambrian anorogenic granitic basement that is intruded by Mesozoic (Jurassic-Cretaceous) units present beneath the La Caridad deposit. The second scenario suggests that the Mesozoic Glance Conglomerate Formation of Arizona underlies the Paleocene volcanic-igneous pile in the La Caridad area.

    Miller, Matthew; Azrael, Deborah; Hemenway, David; Solop, Frederic I

    2002-11-01

    Little is known about the relationship between firearm carrying and hostile behavior on the roadway. To explore a possible association between firearm carrying by drivers and hostile driving behavior we conducted a random-digit-dial survey of 790 licensed drivers in Arizona. In addition to demographic questions, we asked whether respondents had carried a gun while driving in the 12 months prior to the survey. Respondents were also asked if they, in anger, had personally made obscene gestures, cursed or shouted at other drivers, impeded another drivers progress with their vehicle, aggressively 'followed another driver too closely', or brandished a gun at another driver. We used multivariable logistic regression to explore correlates of hostile driving behavior while taking into account several demographic and behavioral characteristics. Overall 11% of drivers always (4%) or sometimes (7%) carried a gun with them in their vehicle; 34% report having made obscene gestures/cursed/shouted angrily; 28% report aggressively following or blocking other drivers with their vehicle. In both crude and multivariate adjusted analyses, self-report of engaging in hostile behavior while driving was significantly more common among men, young adults, and individuals who carried a firearm in their car. Our findings suggest that, at least among Arizona motorists, having a gun in the car is a strong marker for aggressive and illegal behavior behind the wheel.

  20. Energy Efficiency Policy in Arizona Public Participation and Expert Consultation in the Policy Implementation Process

    Science.gov (United States)

    Bryck, Drew

    Many different levels of government, organizations, and programs actively shape the future of energy in Arizona, a state that lacks a comprehensive energy plan. Disparate actions by multiple actors may slow the energy policy process rather than expedite it. The absence of a state energy policy or plan raises questions about how multiple actors and ideas engage with state energy policy development and whether the absence of a comprehensive state plan can be understood. Improving how policy development is conceptualized and giving more focused attention to the mechanisms by which interested parties become involved in shaping Arizona energy policy. To explore these questions, I examine the future energy efficiency. Initially, public engagement mechanisms were examined for their role in policy creation from a theoretical perspective. Next a prominent public engagement forum that was dedicated to the topic of the Arizona's energy future was examined, mapping its process and conclusions onto a policy process model. The first part of this thesis involves an experimental expert consultation panel which was convened to amplify and refine the results of a public forum. The second part utilizes an online follow up survey to complete unfinished ideas from the focus group. The experiment flowed from a hypothesis that formal expert discussion on energy efficiency policies, guided by the recommendations put forth by the public engagement forum on energy in Arizona, would result in an increase in relevance while providing a forum for interdisciplinary collaboration that is atypical in today's energy discussions. This experiment was designed and evaluated utilizing a public engagement framework that incorporated theoretical and empirical elements. Specifically, I adapted elements of three methods of public and expert engagement used in policy development to create a consultation process that was contextualized to energy efficiency stakeholders in Arizona and their unique

    Full Text Available El estudio de las mujeres ha sido un tema marcado por un relativo abandono, es - pecialmente para el caso sonorense, donde es evidente la carencia de acercamientos desde una perspectiva histórica. Si nos referimos al área rural, el vacío historiográfico es mayor, pues el análisis del proceso de colonización del valle del Yaqui, espacio que nos ocupa, se ha concentrado en el reparto agrario. Este artículo recupera las características de la vida cotidiana de las mujeres del ejido José María Morelos (Cajeme, Sonora como punto de partida para la construcción de una visión integral de las condiciones experimentadas durante el siglo xx . Los resultados que se exponen son producto de entrevistas y observa - ciones realizadas de forma sistemática entre 2011 y 2015. Exploramos sus distintas facetas, teniendo como ejes la infancia, el noviazgo, la vida matrimonial y el trabajo en el campo, para identificar los elementos cotidianos que contribuyen a la formación de su identidad como mujeres.

    Full Text Available Conocer el tamaño de las poblaciones es fundamental para estimar universos de necesidad, planear intervenciones y evaluarlas. La estigmatización y criminalización del uso de drogas en México hace que las personas que se las inyectan sean difíciles de alcanzar, sin embargo tienen derecho a la salud, y el Estado está obligado a garantizarla, lo que incluye diseñar acciones efectivas para prevenir el sida. En Hermosillo, Sonora, el peso de la trasmisión del virus de inmunodeficiencia humana por drogas inyectadas ha ganado relevancia en la última década, no obstante, se desconoce el tamaño de la población que se inyecta drogas. En este artículo se describe detalladamente cómo se construye una aproximación mixta de metodologías cualitativas y cuantitativas para estimar el tamaño de dicha población en Hermosillo, y se ofrecen recomendaciones para mejorar los sistemas para registrarla en los servicios de tratamiento de adicciones, y cómo potenciar las intervenciones comunitarias de reducción de daños en la ciudad.

    Full Text Available Cattle ranching is the main activity and the principal user of natural resources in Alamos, Mexico, extending in 93% of this municipality. The objective of this study was to assess the impact of livestock production on natural resources, in the municipio of Alamos, Sonora and in the “Sierra de Álamos-Río Cuchujaqui” nature reserve, which was established in 1996. Overgrazing, deforestation, botanical composition of the rangeland, soil cover and soil erosion risk were the main indicators evaluated. From 1995 to 2005 livestock herd size increased by 13%. By the year 2005, overgrazing was over 200% in all the sites evaluated, (reaching values as high as 550%, taking as a reference COTECOCA (the Mexican agency for the determination of rangeland grazing load recommendations for animal rangeland load. Deforested area within the nature reserve remained relatively unchanged in 5,150 ha between 1996 and 2006. In the 155 sites sampled for vegetation and soil cover, on the other hand, we found a low percentage of cattle-preferred species, whereas species with low nutritional quality and less preferred by the cattle, represented 65 to 90% of the identified plants.

    Full Text Available En el presente trabajo se analiza el mercado laboral en Sonora y los demás estados de la frontera norte de México, a partir de la evolución de la industria maquiladora y su relación con el empleo y los salarios regionales. Para una economía de bienes comercializables y no comercializables, que utiliza un modelo en el que el comercio internacional influye sobre el empleo y los salarios de la región, y con base en una estimación con datos de panel, se estudia el efecto de la demanda del empleo y los salarios provenientes de la demanda de exportaciones de bienes manufacturados sobre el sector no maquilador, de 1997 a 2004, con énfasis en la etapa de cierre de empresas maquiladoras en 2001 y 2003. Los resultados sugieren que, para este periodo en particular, el empleo en los sectores distintos a la maquila determina el equilibrio en el mercado de trabajo, y que los salarios de las maquiladoras son influidos por el equilibrio en la oferta y demanda de dichos sectores.

    Aspergillus flavus frequently contaminates maize, a critical staple of billions, with aflatoxins. Diversity among A. flavus L morphotype populations associated with maize in Sonora, Mexico was assessed and a total of 869 isolates from 83 fields were placed into 136 vegetative compatibility groups (VCGs) using nitrate-nonutilizing mutants. VCG diversity indices did not differ in four agroecosystems (AES) but diversity significantly differed among years. Frequencies of certain VCGs changed manyfold over single years in both multiple fields and multiple AES. Certain VCGs were highly frequenct (>1%) in 2006, but frequencies declined repeatedly in each of the two subsequent years. Other VCGs that had low frequencies in 2006 increased in 2007 and subsequently declined. None of the VCGs were consistently associated with any AES. Fourteen VCGs were considered dominant in at least a single year. However, frequencies often varied significantly among years. Only 9% of VCGs were detected all three years while 66% were detected in only one year. Results suggest that the most realistic measurements of both genetic diversity and the frequency of A. flavus VCGs are obtained by sampling multiple locations in multiple years. Single season sampling in many locations should not be substituted for sampling over multiple years.

    Full Text Available La diversidad cultural y la problemática ambiental del agua en el estado de Sonora convergen en el presente trabajo, abordadas desde la perspectiva de la ecología política y la diversidad biocultural mediante un análisis transdisciplinario. Se distingue entre el acceso al agua para la subsistencia tradicional del agua para el desarrollo. Se advierten tendencias generalizadas de despojo de los territorios indígenas y sus recursos naturales, en las que los conflictos por el agua para la subsistencia son cada vez más graves, que exacerban la vulnerabilidad de las comunidades y la desorganización del complejo biocultural. El servicio del agua potable no tiene las condiciones para impulsar el desarrollo comunitario sustentable. Estas tendencias no son homogéneas, y se observan posibilidades de reconfiguración. Se requiere precisar el análisis para aportar al desarrollo de los pueblos indígenas, desde una plataforma biocultural contemporánea, en pleno respeto de sus derechos humanos individuales y colectivos.

    2017-02-01

    Full Text Available Pervasive social and ecological water crises in Mexico remain, despite over two decades of legal and institutional backing for Integrated Water Resources Management (IWRM as a policy tenet. In this article we apply a socialshed analysis to uncover and understand the geographical and jurisdictional forces influencing the social construction and simultaneous fragmentation of the San Miguel Watershed (SMW in the state of Sonora, in Mexico’s water-scarcity bulls-eye. Specific insights derived from an empirical analysis include that water management (WM is socially embedded in dense networks of family and friends, farmers and ranchers, citizens and local government – all to varying degrees sharing information about local water crises. Irrigation water user representatives (WUR are connected across communities and within their own municipalities, but inter-watershed social links with other WUR are virtually nonexistent, despite high levels of awareness of cross-municipality WM problems. Implementation of IWRM as a federal policy by a single agency and the creation of basin councils and subsidiary technical committees for groundwater management have not been sufficient for technical – much less social – integration at the watershed level. This study shows that the SMW socialshed remains fragmented by local jurisdictions; without coordinated agency-jurisdiction-local action fomenting social connections, a socialshed will not emerge.

    Full Text Available The objective of this research was to evaluate the potential yield and fruit quality of 10 beef tomatoes hybrids using a low level technology greenhouse and desertic conditions of Northwest of Sonora. This experiment was done during two years 2005 and 2006 at the Experimental Station of Caborca, INIFAP. The yield reached during both years was of 25.2 kg m-2 but 89.1% of this production was harvested during February to May. The tomatoes hybrids with higher yield were Zuni, Gironda and Charleston with 31.1, 28.2 and 26.7 kg m-2, respectively; while Thomas, Rapsodie, Sedona and Beatrice were the lowest yield with 20.1, 22.4, 23.1 and 24.9 kg m-2, respectively. By other side, the hybrids with better fruit weight in both years were Sedona and Charleston with 211.3 and 209.8 and 194.7 grams fruit-1. Also, there were differences among tomatoes hybrids on physiological disorders susceptibility (fruit cracking and blossom end rot. For this reason, adequate selection of the tomatoes hybrid is a good alternative for increase yield and fruit quality and reduction of physiological disorders.

  13. Solar energy system performance evaluation: Seasonal report for Elcam Tempe Arizona State University, Tempe, Arizona

    Science.gov (United States)

    1980-01-01

    The solar system, Elcam-Tempe, was designed by Elcam Incorporated, Santa Barbara, California, to supply commercial domestic hot water heating systems to the Agriculture Department residence at Arizona State University. The building is a single story residence located at the agriculture experiment farm of the Arizona State University. The energy system's four modes of operation are described. Electrical energy savings at the site was a net of 5.54 million Btu after the 0.17 million Btu of operating energy required to operate collector loop circulating pump were subtracted. The energy savings due to solar was less than the system's potential. On an average, twice as much hot water could have been used with significant solar energy contribution. The system corrosion and deposits caused by using dissimilar metals in the collector loop was the only problem noted with the Elcam-Tempe system.

    James, J S

    1996-11-15

    Both California and Arizona have passed State legislation allowing medical use of marijuana, however, the law may now be unenforceable because of Federal laws against marijuana use for any reason. It is believed that some middle ground between allowing limited use of marijuana and outright banning is necessary considering today's medical needs. Among the demographic breakdowns on support of Proposition 215, allowing medicinal use of marijuana, was the observation that parents with children under 18 showed almost as much support for its passage as other adults, indicating no fear of it becoming abused by youth. Despite polls repeatedly showing support for the right to use marijuana for medical purposes, 44.3 percent still voted against it. The reasons are not known, but it is suggested that if the objections could be found and responded to, the initiative may work well enough to be an effective national model.

    1979-05-01

    Exploration for Hot Dry Rock (HDR) requires the ability to delineate areas of thermal enhancement. It is likely that some of these areas will exhibit various sorts of anomalous conditions such as seismic transmission delays, low seismic velocities, high attenuation of seismic waves, high electrical conductivity in the crust, and a relatively shallow depth to Curie point of Magnetization. The Aquarius Mountain area of northwest Arizona exhibits all of these anomalies. The area is also a regional Bouguer gravity low, which may indicate the presence of high silica type rocks that often have high rates of radioactive heat generation. The one deficiency of the area as a HDR prospect is the lack of a thermal insulating blanket.

    Between 1978 and 1983, Petróleos Mexicanos (PEMEX) carried on an intense exploration program in the northern Gulf of California, the Sonora Desert and the southern part of the Mexicali Valley. This program was supported by a seismic reflection field operation. The collected seismic data was 2D, with travel time of 6 s recording, in 48 channels, and the source energy was: dynamite, vibroseis and air guns. Since 2007 to present time, the existing seismic data has been re-processing and ire-interpreting as part of a collaboration project between the PEMEX's Subdirección de Exploración (PEMEX) and CICESE. The study area is located along a large portion of the Pacific-North America plate boundary in the northern Gulf of California and the Southern part of the Salton Trough tectonic province (Mexicali Valley). We present the result of the processes reflection seismic lines. Many of the previous reported known faults were identify along with the first time described located within the study region. We identified regions with different degree of tectonic activity. In structural map it can see the location of many of these known active faults and their associated seismic activity, as well as other structures with no associated seismicity. Where some faults are mist placed they were deleted or relocated based on new information. We included historical seismicity for the region. We present six reflection lines that cross the aftershocks zone of the El Mayor-Cucapah earthquake of April 4, 2010 (Mw7.2). The epicenter of this earthquake and most of the aftershocks are located in a region where pervious to this earthquake no major earthquakes are been reported. A major result of this study is to demonstrate that there are many buried faults that increase the seismic hazard.

    The U.S. Geological Survey (USGS) Arizona District collects data from automated streamflow stations for a wide variety of uses. Data from these stations are provided to Federal, State, and local agencies that have a responsibility to issue flood warnings; to generate forecasts of water availability; to monitor flow to insure compliance with treaties and other legal mandates; and to manage reservoirs for hydropower, flood abatement, and municipal and irrigation water supply. In the mid-1970's, the escalation of data collection costs and a need for more timely data led the Arizona District to examine alternatives for remote data acquisition. On the basis of successful data communications experiments with NASA 's Landsat satellite, an operational system for satellite-data relay was developed in 1976 using the National Oceanic and Atmospheric Administrations 's (NOAA) Geostationary Operational Environmental Satellite (GOES). A total of 62 data collection platforms (DCP's) was operated in 1983. Satellite telemetry operations are controlled at the remote data-collection stations by small battery-operated data collection platforms. The DCP 's periodically collect data from the sensors, store the data in computer memory, and at preset times transmit the data to the GOES satellite. The satellite retransmits the data to Earth where a ground-receive station transmits or transfers the data by land communications to the USGS computer in Reston, Virginia, for processing. The satellite relay transfers the data from sensor to computer in minutes; therefore, the data are available to users on a near real-time basis. (Author 's abstract)

    Ibervillea sonorae (S. Watson) Greene (Cucurbitaceae), a plant used for the empirical treatment of type 2 diabetes in México, exerts antidiabetic effects on animal models but its mechanism of action remains unknown. The aim of this study is to investigate the antidiabetic mechanism of an Ibervillea sonorae aqueous extract (ISE). Non-toxic ISE concentrations were assayed on the glucose uptake by insulin-sensitive and insulin-resistant murine and human cultured adipocytes, both in the absence or the presence of insulin signaling pathway inhibitors, and on murine and human adipogenesis. Chemical composition of ISE was examined by spectrophotometric and HPLC techniques. ISE stimulated the 2-NBDGlucose uptake by mature adipocytes in a concentration-dependent manner. ISE 50 µg/ml induced the 2-NBDG uptake in insulin-sensitive 3T3-F442A, 3T3-L1 and human adipocytes by 100%, 63% and 33%, compared to insulin control. Inhibitors for the insulin receptor, PI3K, AKT and GLUT4 blocked the 2-NBDG uptake in murine cells, but human adipocytes were insensitive to the PI3K inhibitor Wortmannin. ISE 50 µg/ml also stimulated the 2-NBDG uptake in insulin-resistant adipocytes by 117% (3T3-F442A), 83% (3T3-L1) and 48% (human). ISE induced 3T3-F442A adipogenesis but lacked proadipogenic effects on 3T3-L1 and human preadipocytes. Chemical analyses showed the presence of phenolics in ISE, mainly an appreciable concentration of gallic acid. Ibervillea sonorae exerts its antidiabetic properties by means of hydrosoluble compounds stimulating the glucose uptake in human preadipocytes by a PI3K-independent pathway and without proadipogenic effects.

  1. Experimental Floods in a Time of Drought: The 2014 Pulse Flow in the Lower Colorado River, Arizona, USA, and Mexico

    Kennedy, J.; Ramirez-Hernandez, J.; Ramirez, J.

    2015-12-01

    In March and April, 2014, an unprecedented experimental "pulse flow" with a total volume of over 100 million cubic meters (81,000 acre-feet) of water was released from Morelos Dam into the normally dry lower Colorado River below Yuma, Arizona, for the primary purpose of restoring native vegetation and habitat. Significant infiltration and attenuation of the flood peak occurred within the limitrophe reach that forms the US-Mexico border, with total volume reduced to 57 million cubic meters at the southerly international boundary at San Luis Rio Colorado, Sonora, Mexico (32 kilometers downstream). Groundwater levels in piezometers adjacent to the stream channel rose as much as 10 meters, and surface water/groundwater connection was established throughout the reach, despite depths-to-water greater than 15 meters prior to the pulse flow. Based on groundwater levels, a groundwater mound remained in the vicinity of the stream channel for several months but had largely dissipated into the regional groundwater system by fall 2014. Ultimately, a large amount of water was moved from storage in an upstream reservoir (Lake Mead), where it is potentially available to many users but where evaporation losses can be high, to the regional aquifer in the Yuma-Mexicali area, where the water could be available to local users but cannot be precisely quantified as it moves through the groundwater system. During a time of drought, tradeoffs between local vs. upstream storage, and reservoir vs. subsurface storage, will likely be increasingly important considerations in planning future experimental floods on the Colorado River.

  2. Application of Hydrologic Tools and Monitoring to Support Managed Aquifer Recharge Decision Making in the Upper San Pedro River, Arizona, USA

    Full Text Available The San Pedro River originates in Sonora, Mexico, and flows north through Arizona, USA, to its confluence with the Gila River. The 92-km Upper San Pedro River is characterized by interrupted perennial flow, and serves as a vital wildlife corridor through this semiarid to arid region. Over the past century, groundwater pumping in this bi-national basin has depleted baseflows in the river. In 2007, the United States Geological Survey published the most recent groundwater model of the basin. This model served as the basis for predictive simulations, including maps of stream flow capture due to pumping and of stream flow restoration due to managed aquifer recharge. Simulation results show that ramping up near-stream recharge, as needed, to compensate for downward pumping-related stress on the water table, could sustain baseflows in the Upper San Pedro River at or above 2003 levels until the year 2100 with less than 4.7 million cubic meters per year (MCM/yr. Wet-dry mapping of the river over a period of 15 years developed a body of empirical evidence which, when combined with the simulation tools, provided powerful technical support to decision makers struggling to manage aquifer recharge to support baseflows in the river while also accommodating the economic needs of the basin.

  8. Life history attributes of Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus) and comparisons with other North American subspecies

    Science.gov (United States)

    Ruth, Janet M.

    2017-01-01

    Ammodramus savannarum ammolegus—commonly referred to as the Arizona Grasshopper Sparrow—occurs in the desert and plains grasslands of southeastern Arizona, southwestern New Mexico, and northern Sonora, Mexico. Although a subspecies of conservation concern, this is the first intensive study of its life history and breeding ecology, providing baseline data and facilitating comparisons with other North American Grasshopper Sparrow subspecies. Specifically, I found A. s. ammolegus males generally weighed less than other subspecies (16.0 ± 0.8 g) but with intermediate exposed culmen length (11.6 ± 0.5 mm) and wing chord length similar to the other two migratory subspecies (62.7 ± 1.5 mm). Territory size for A. s. ammolegus was 0.72 ± 0.37 ha, with some variation between sites and among years, possibly indicating variation in habitat quality across spatial and temporal scales. The return rate for A. s. ammolegus males was 39.2%. Nest initiation for A. s. ammolegus was early to mid-July after the monsoons had begun. Domed nests were constructed on the ground, primarily under native bunch grasses, and frequently with a tunnel extending beyond the nest rim, with nest openings oriented north. Clutch size was 3.97 ± 0.68, with no evidence of Brown-headed Cowbird (Molothrus ater) nest parasitism. Extreme climate factors in the arid Southwest may have affected the life history and morphology of A. s. ammolegus as compared to other subspecies, influencing body size and mass, culmen length, breeding phenology, and nest orientation. Other geographic variation occurred in return rates, clutch size, and nest parasitism rates. The baseline data for A. s. ammolegus obtained in this study will inform future taxonomic and ecological studies as well as conservation planning. Comparisons of A. s. ammolegus morphometrics with those of other subspecies will assist field biologists in distinguishing among subspecies where they overlap, especially on wintering grounds.

    Full Text Available Este artículo examina críticamente la experiencia del Banco Grameen (BG de Bangladesh a fin de comprender los elementos esenciales de su operación. El BG es una institución única en su género que ha logrado desarrollar un método efectivo para llegar a los más pobres de los pobres. Este banco elaboró un modelo financiero que sustituye los requerimientos de garantías colaterales en los préstamos por la responsabilidad de los grupos. El BG organiza a los individuos pobres en grupos, con lo que los hace socialmente aptos para recibir crédito. El modelo de intermediación financiera que esta institución practica, mejora la productividad y el ingreso de la gente pobre. De la misma manera, la aplicación del modelo contribuye a elevar la tasa de recuperación de créditos, lo que a su vez aumenta la viabilidad financiera de la institución. Asimismo, este documento presenta un diseño y un plan de negocios para implantar un prototipo del BG en el poblado Miguel Alemán, municipio de Hermosillo, Sonora. Replicar el modelo Grameen en el México rural es un reto que exige importantes adaptaciones al modelo original. Las diferencias sociales, culturales y religiosas entre México y Bangladesh exigen consideraciones especiales al establecer los métodos administrativos y operativos de un programa de crédito del estilo Grameen. Sin embargo, basados en el plan de negocios, se ha considerado que un programa de crédito para mujeres pobres en la Costa de Hermosillo tiene viabilidad económica y perdurabilidad en el tiempo.

  10. Sonora: A New Generation Model Atmosphere Grid for Brown Dwarfs and Young Extrasolar Giant Planets

    2017-01-01

    Brown dwarf and giant planet atmospheric structure and composition has been studied both by forward models and, increasingly so, by retrieval methods. While indisputably informative, retrieval methods are of greatest value when judged in the context of grid model predictions. Meanwhile retrieval models can test the assumptions inherent in the forward modeling procedure. In order to provide a new, systematic survey of brown dwarf atmospheric structure, emergent spectra, and evolution, we have constructed a new grid of brown dwarf model atmospheres. We ultimately aim for our grid to span substantial ranges of atmospheric metallilcity, C/O ratios, cloud properties, atmospheric mixing, and other parameters. Spectra predicted by our modeling grid can be compared to both observations and retrieval results to aid in the interpretation and planning of future telescopic observations. We thus present Sonora, a new generation of substellar atmosphere models, appropriate for application to studies of L, T, and Y-type brown dwarfs and young extrasolar giant planets. The models describe the expected temperature-pressure profile and emergent spectra of an atmosphere in radiative-convective equilibrium for ranges of effective temperatures and gravities encompassing 200 less than or equal to T(sub eff) less than or equal to 2400 K and 2.5 less than or equal to log g less than or equal to 5.5. In our poster we briefly describe our modeling methodology, enumerate various updates since our group's previous models, and present our initial tranche of models for cloudless, solar metallicity, and solar carbon-to-oxygen ratio, chemical equilibrium atmospheres. These models will be available online and will be updated as opacities and cloud modeling methods continue to improve.

El objetivo del trabajo consistió en realizar un listado de la flora silvestre ribereña del Río Mayo, localizado en el sur del estado de Sonora, para conocer su composición. La recolección de especímenes se realizó mediante la técnica de intercepción o línea de Canfield (1941, en 15 sitios con dos repeticiones sumando 30 transectos. Se encontraron un total de 40 familias, 79 géneros y 99 especies. Las familias mejor representadas fueron: Leguminoseae, Cactaceae, Gramineae, Compositae, Chenopodiaceae, Salicaceae, Solanaceae, Euphorbiaceae, Amaranthaceae y Asteraceae. La dominante fue Leguminoseae con vegetación de bosque espinoso compuesta por Acacia cymbispina, Acacia farnesiana, Parkinsonia aculeata y Prosopis juliflora. Resulta perceptible la pérdida de flora debido al cambio de uso de suelo. Especies representativas de la zona riparia como Populus fremontii y Salix bonplandiana están desapareciendo por alteración del ecosistema. Poblaciones de mangle como Rhizophora mangle y Conocarpus erectus están disminuidas. El área estudiada es rica en especies a pesar de la perturbación. La diversidad varía de acuerdo al gradiente altitudinal y el número de especies guarda relación con los géneros y familias recolectadas. La agricultura, acuicultura, ganadería, la industria pesquera y la urbanización, son los giros que causan mayor afectación en los ecosistemas

    Full Text Available En el noroeste del estado de Sonora existe una región árida cubierta por un escudo volcánico, cercana a un complejo de dunas y al mar de Cortez. Allí la temperatura puede alcanzar los 56.7°C en el verano, y descender hasta los -8.3°C en invierno. Con 52 milímetros de precipitación pluvial anual, podría pensarse que ese lugar es un páramo sin vida. No obstante, el desierto de Altar y el escudo volcánico de El Pinacate se han caracterizado, desde el pleistoceno, por la presencia de una rica biodiversidad, de la cual perduran cientos de especies de plantas y animales adaptados a las condiciones actuales; debido a ello, el gobierno mexicano declaró a esta zona área natural protegida, con la denominación de Reserva de la Biosfera El Pinacate y Gran Desierto de Altar. Esta región es relevante por sus particularidades fisiográficas y ambientales, por haber sido habitada por el hombre desde el periodo paleoindio y por las múltiples exploraciones de misioneros, colonizadores, gambusinos, cazadores y, sobre todo, de científicos, desde el siglo xvii hasta el presente. Este artículo presenta ambas historias, la natural y la cultural, y discute aspectos importantes de la geología, morfología y fisiografía de la zona, de su biodiversidad, así como de su poblamiento temprano y exploración posterior. Es el resultado de una investigación realizada con el propósito de generar un guión museográfico que se materialice en una exposición permanente albergada por el Centro de Visitantes Shuk Toak.

    Full Text Available México posee gran cantidad de recursos minerales producto de la naturaleza, por lo que su explotación a través de la minería y el cuidado del medio ambiente deben de coexistir de una manera armoniosa. A través del tiempo la minería ha desempeñado un papel fundamental en la vida económica del país, ya que su desarrollo ha permitido que en la actualidad sea la tercera fuente generadora de ingresos. Asimismo, la minería permite que se desarrollen actividades, como la agrícola y la industrial (automotriz, acerera, cinematográfica, etcétera, entre otras. A nivel mundial, México ocupa el primer lugar en producción de plata, existiendo otros minerales metálicos importantes, como el oro, plomo, hierro, zinc, cobre, uranio y torio. Se considera a la minería como una actividad económica primaria debido a que los minerales se toman directamente de la naturaleza, encontrándose sobre la superficie o bien en el subsuelo a diferentes profundidades. Algunos de los principales centros mineros se localizan al norte del país, pero en los últimos años, Sonora se ha revelado como el estado productor de minerales más importante de México. Los principales minerales son: cobre y metales preciosos, como el oro y la plata. Por ello en el presente artículo, se mencionan los usos más comunes de estos metales, así como su ocurrencia en el estado, y su importancia económica a escala regional.

    The Northern Counties Area Development Plan evaluated the regional market potential for utilizing geothermal energy. This study identified five potential geothermal resource areas, four of which have low temperature (<90{sup 0}C, 194{sup 0}F) potential and one possible igneous system. The average population growth rate in the Northern Counties is expected to be five percent per year over the next 40 years, with Mohave and Yavapai Counties growing the fastest. Rapid growth is anticipated in all major employment sectors, including trade, service, manufacturing, mining and utilities. A regional energy use analysis is included, containing information on current energy use patterns for all user classes. Water supplies are expected to be adequate for expected growth generally, though Yavapai and Gila Counties will experience water deficiencies. A preliminary district heating analysis is included for the towns of Alpine and Springerville. Both communities are believed located on geothermal resource sites. The study also contains a section identifying potential geothermal resource users in northern Arizona.

    A mineral survey has shown that the Mazatzal Wilderness, Arizona has demonstrated resources of silver, gold, lead and mercury, small areas of substantiated mineral-resource potential for silver and copper, and areas of probable resource potential for resources of silver, copper, lead, mercury, and molybdenum. Gold, silver, and copper resources occur in small deposits in the north-central, eastern, and southern parts of the wilderness. A small demonstrated mercury resource is located at the Sunflower mine near the southeastern corner of the wilderness adjacent to the well-known Sunflower mining district. Molybdenum mineralization found during this study in the Tangle Creek area west of the Verde River may extend eastward into the roadless area and the wilderness. Tin occurrences not previously known in the Mazatzal region were found in the central part of the wilderness, and uranium was found near Horseshoe Reservoir, but there is little promise for the occurrence of tin and uranium resources. No potential for fossil fuel resources was identified in this study.

    2003-04-01

    The successful case was presented to us to study the structure and composition of two fulgurit fragments of Sonora desert (south of Mexico). Earlier we have studied the fulgurite from area of Nigoziro in Karelia, Russia, which was formed on a carbon-containing aleurolits. So we make the comparative analysis of fulgurits, formed on completely various geological breeds. We use several methods such as: X-Ray analysis, the thermal analysis, Mossbauer spectroscopy, infra-red spectroscopy, electronic microscopy. By data received with the help of X-Ray analysis the basic volume of all investigated fulgurite glasses is the X-Ray amorphous phase. For Mexican fulgurite it is a prevailing phase. Also we expose the heterogeneity of glasses which consists in combined presence of amorphous glassy matrix and crystalline formations with differ composition: orthoclase, hematite, chlorite, pyrite. The state of iron in fulgurite was studied with the help of Mossbauer spectroscopy. In spectrum distinguish fore double-peaks of iron. One double-peak of trivalent iron in tetrahedral position ( =0.32), which contains 4.1% of all iron, and three double-peaks of divalent iron in octahedral positions. The content of iron at that positions accordingly 33.9; 30.4; 31.6% from all amount of iron. The infra-red spectrums of fulgurites consists from the typical for the silicate glasses absorption stripes, which connected with the oscillation of silicium-oxygen carcass of glassy fulgurite substance. Also we find several narrow stripes of crystalline quartz which is an evidence of crystalline quartz presence in felsphatic fusion. By the micro-probe analysis we determined that the main mass of glassy fulgurite substance is a thicken Si-Al-Fe fusion. In the main mass of fusion the areas of almost pure glasses are distinguished. The simultaneous appearance of fragments as glassy such as residual quartz in fusion tells that the temperature of fusion in that zone was near the temperature of quartz

  16. Potential of utilization of geothermal energy in Arizona

    Science.gov (United States)

    White, D. H.; Goldstone, L. A.

    1982-08-01

    Arizona is one of the fastest growing states in the United States. It is in the midst of the movement of the population of the United States from its cold regions to the warm Southwest. Being a hot, arid region, its electrical demand is nearly 50% higher in the peak hot summer months than that of the other 7 months. The major uncertainty of utilizing geothermal energy in Arizona is that very little exploration and development have occurred to date. The potential for utilizing geothermal energy in Arizona is good based on the fat thatthere are over 3000 thermal wells in Arizona out of a total of about 30,000 shallow irrigation wells that were examined. There is much young volcanic rock in Arizona. The combination of data from thermal wells, young volcanic rock, water geochemistry and other geological tools, indicate that there is a large geothermal resource throughout the southern half of the state. It is suggested that most of this resource is in the range of 500 to 1500 C, limiting its uses to direct heat utilization rather than for electric power generation.

    A quantitative accuracy assessment was performed for the vegetation classification map produced as part of the Arizona Vegetation Resource Inventory (AVRI) project. This project was a cooperative effort between the Bureau of Land Management (BLM) and the Earth Resources Observation Systems (EROS) Data Center. The objective of the accuracy assessment was to estimate (with a precision of ?10 percent at the 90 percent confidence level) the comission error in each of the eight level II hierarchical vegetation cover types. A stratified two-phase (double) cluster sample was used. Phase I consisted of 160 photointerpreted plots representing clusters of Landsat pixels, and phase II consisted of ground data collection at 80 of the phase I cluster sites. Ground data were used to refine the phase I error estimates by means of a linear regression model. The classified image was stratified by assigning each 15-pixel cluster to the stratum corresponding to the dominant cover type within each cluster. This method is known as stratified plurality sampling. Overall error was estimated to be 36 percent with a standard error of 2 percent. Estimated error for individual vegetation classes ranged from a low of 10 percent ?6 percent for evergreen woodland to 81 percent ?7 percent for cropland and pasture. Total cost of the accuracy assessment was $106,950 for the one-million-hectare study area. The combination of the stratified plurality sampling (SPS) method of sample allocation with double sampling provided the desired estimates within the required precision levels. The overall accuracy results confirmed that highly accurate digital classification of vegetation is difficult to perform in semiarid environments, due largely to the sparse vegetation cover. Nevertheless, these techniques show promise for providing more accurate information than is presently available for many BLM-administered lands.

    The subject document reports the results of an in-depth investigation of the fiscal year 1992 cost of the city of Scottsdale, Arizona, integrated municipal solid waste management (IMSWM) system, the energy consumed to operate the system, and the environmental performance requirements for each of the system`s waste-processing and disposal facilities. The document reports actual data from records kept by participants. Every effort was made to minimize the use of assumptions, and no attempt is made to interpret the data reported. Analytical approaches are documented so that interested analysts may per-form manipulation or further analysis of the data. As such, the report is a reference document for municipal solid waste (MSW) management professionals who are interested in the actual costs and energy consumption, for a 1-year period, of an operating IMSWM system. The report is organized into two main parts. The first part is the executive summary and case study portion of the report. The executive summary provides a basic description of the study area and selected economic and energy information. Within the case study are detailed descriptions of each component operating during the study period; the quantities of solid waste collected, processed, and marketed within the study boundaries; the cost of MSW in Scottsdale; an energy usage analysis; a review of federal, state, and local environmental requirement compliance; a reference section; and a glossary of terms. The second part of the report focuses on a more detailed discourse on the above topics. In addition, the methodology used to determine the economic costs and energy consumption of the system components is found in the second portion of this report. The methodology created for this project will be helpful for those professionals who wish to break out the costs of their own integrated systems.

  1. Causes of sinks near Tucson, Arizona, USA

    Hoffmann, John P.; Pool, Donald R.; Konieczki, A. D.; Carpenter, Michael C.

    Land subsidence in the form of sinks has occurred on and near farmlands near Tucson, Pima County, Arizona, USA. The sinks occur in alluvial deposits along the flood plain of the Santa Cruz River, and have made farmlands dangerous and unsuitable for farming. More than 1700 sinks are confined to the flood plain of the Santa Cruz River and are grouped along two north-northwestward-trending bands that are approximately parallel to the river and other flood-plain drainages. An estimated 17,000m3 of sediment have been removed in the formation of the sinks. Thirteen trenches were dug to depths of 4-6m to characterize near-surface sediments in sink and nonsink areas. Sediments below about 2m included a large percentage of dispersive clays in sink areas. Sediments in nonsink areas contain a large component of medium- to coarse-grained, moderately to well sorted sand that probably fills a paleochannel. Electromagnetic surveys support the association of silts and clays in sink areas that are highly electrically conductive relative to sand in nonsink areas. Sinks probably are caused by the near-surface process of subsurface erosion of dispersive sediments along pre-existing cracks in predominantly silt and clay sediments. The pre-existing cracks probably result from desiccation or tension that developed during periods of water-table decline and channel incision during the past 100 years or in earlier periods.

    Development of pyriproxyfen and neonicotinoid resistance in the B-biotype whitefly and recent introduction of the Q biotype have the potential to threaten current whitefly management programs in Arizona. The possibility of integrating the novel anthranilic diamides chlorantraniliprole and cyantraniliprole into the current program to tackle these threats largely depends on whether these compounds have cross-resistance with pyriproxyfen and neonicotinoids in whiteflies. To address this question, the authors bioassayed a susceptible B-biotype strain, a pyriproxyfen-resistant B-biotype strain, four multiply resistant Q-biotype strains and 16 B-biotype field populations from Arizona with a systemic uptake bioassay developed in the present study. The magnitude of variations in LC(50) and LC(99) among the B-biotype populations or the Q-biotype strains was less than fivefold and tenfold, respectively, for both chlorantraniliprole and cyantraniliprole. The Q-biotype strains were relatively more tolerant than the B-biotype populations. No correlations were observed between the LC(50) (or LC(99)) values of the two diamides against the B- and Q-biotype populations tested and their survival rates at a discriminating dose of pyriproxyfen or imidacloprid. These results indicate the absence of cross-resistance between the two anthranilic diamides and the currently used neonicotinoids and pyriproxyfen. Future variation in susceptibility of field populations to chlorantraniliprole and cyantraniliprole could be documented according to the baseline susceptibility range of the populations tested in this study.

    In early April 2003, fishermen from Kino Bay Sonora alerted us about a massive die-off of fish and mollusks occurring at Kun Kaak Bay. Phytoplankton samples taken on 17 May 2003 reported the presence of a harmful algal bloom composed of Chatonella marina, Chatonella cf. ovata, Gymnodinium catenatum and Gymnodinium sanguineum. On 22 of May, we collected samples of water, sediment and organisms at the affected area. Physicochemical parameters and nutrients were measured in water samples from different depths. Sediment and benthic organisms were analyzed for Cd, Cu, Zn, Pb and Hg. We found concentrations of heavy metals higher than background levels for this area. Cadmium and Lead concentrations in sediment from the HAB area were up to 6x greater than background levels and Cd in mollusks was 8x greater than regulations allow. A relationship between elevated Cd and Pb concentrations in sediment and the survival of toxic dinoflagellates is suspected.

    A survey was designed to know the concentration of Naegleria fowleri in recreational areas in Hornos, Sonora, during a year. Samples were taken monthly at La Isleta and Las Palmas and the total amoeba counts were obtained by the most probable number method (MPN). The identification of N. fowleri was made by PCR. The maximum concentration of total thermophilic amoebae was 9175 MPN/L for La Isleta and 3477 MPN/L for Las Palmas. Thermophilic Naegleria were present mainly during summer and fall. October's concentrations were up to 201 MPN/L, at both places. The maximum concentrations of N. fowleri were 201 MPN/L and 18 MPN/L for La Isleta and Las Palmas respectively, and were isolated from August to October. The presence of N. fowleri in these particular natural bodies of water reinforces the need for adaptation of preventive measures to avoid cases of primary amoebic meningoencephalitis.

    The Mesa Formation extends from Cananea, Mexico, southeast to the Sonora River and is the main host rock of Laramide porphyry copper deposits in the Cananea District and at the Alacran porphyry prospect to the east. The Mesa consists of two members-a lower andesite and an upper dacite. The lowest part of the dacite member is a crystal tuff about 100 m thick. This tuff is the outfall of a caldera centered near the village of Ojo de Agua, dated by 40Ar/39Ar at 65.8 Ma ?0.4. The Ojo de Agua Caldera is about 9 km in diameter and is filled by a light gray biotite dacite tuff with abundant flattened pumice fragments. The volume of the caldera is estimated to be 24 km3.

Porém, o campo de Bresson não é um idílio imaculado, como na concepção idealizada de Schafer, sendo sua atmosfera de crueldade mais próxima daquela dos livros de Georges Bernanos adaptados pelo diretor. Além disso, as qualidades musicais dos ruídos nos seus filmes, junto com o silêncio, constroem uma espécie de música concreta.

    The University of Arizona (University) research reactor is a TRIGA swimming pool type reactor designed by General Atomics and constructed at the University in 1958. The reactor first went into operation in December of 1958 under U.S. Nuclear Regulatory Commission (NRC) license R-52 until final shut down on May 18, 2010. Initial site characterization activities were conducted in February 2009 during ongoing reactor operations to assess the radiological status of the Nuclear Reactor Laboratory (NRL) excluding the reactor tank, associated components, and operating systems. Additional post-shutdown characterization activities were performed to complete characterization activities as well as verify assumptions made in the Decommissioning Plan (DP) that were based on a separate activation analysis (ESI 2009 and WMG 2009). Final status survey (FSS) activities began shortly after the issuance of the FSS plan in May 2011. The contractor completed measurement and sampling activities during the week of August 29, 2011.

    Full Text Available La alimentación se considera un fenómeno biocultural, ya que cumple funciones biológicas de supervivencia y se basa en componentes culturales que se encuentran asociados a los patrones de consumo de los individuos. Desde el punto de vista de marketing, los elementos culturales, junto con las características de los productos, así como sus valores simbólicos, emocionales, de seguridad, de riesgo percibido y personales, pueden llegar a condicionar las elecciones y preferencias de los individuos. Cuando se trata de alimentos tradicionales, resulta probable que la conjugación de elementos culturales y del producto se vuelvan fundamentales en las decisiones de los consumidores. Al analizar alimentos tradicionales/típicos, se los puede identificar desde una visión “nacional”; sin embargo, se trata de una perspectiva muy generalista, ya que dentro de un mismo territorio existe una amplia variabilidad alimentaria. Los componentes y características regionales también pueden variar y favorecer con ello la formación de una identidad gastronómica regional. En esta línea, la investigación que se realiza se centra específicamente en los alimentos tradicionales de Sonora -estado ubicado al noroeste de México-, en donde existe una cocina que mantiene elementos en común con la tradicional cocina mexicana, pero que a su vez tiene un sentido emblemático y de identidad regional. En este contexto, el objetivo general de esta investigación es analizar la influencia que ejercen distintos atributos sobre la satisfacción del consumidor respecto a los alimentos tradicionales sonorenses. Para ello, primero se analiza cómo la calidad extrínseca afecta la seguridad y confianza alimentaria, y cómo a su vez la seguridad, confianza y conveniencia alimentaria influyen sobre la satisfacción del consumidor. Para llevar a cabo la investigación se ha realizado un muestreo aleatorio estratificado considerando la edad y el género como los criterios de

    2000-01-01

    The Grand Canyon is one of North America's most spectacular geologic features. Carved primarily by the Colorado River over the past six million years, the canyon sports vertical drops of 5,000 feet and spans a 445-kilometer-long stretch of Arizona desert. The strata along the steep walls of the canyon form a record of geologic time from the Paleozoic Era (250 million years ago) to the Precambrian (1.7 billion years ago).The above view was acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument aboard the Terra spacecraft. Visible and near infrared data were combined to form an image that simulates the natural colors of water and vegetation. Rock colors, however, are not accurate. The image data were combined with elevation data to produce this perspective view, with no vertical exaggeration, looking from above the South Rim up Bright Angel Canyon towards the North Rim. The light lines on the plateau at lower right are the roads around the Canyon View Information Plaza. The Bright Angel Trail, which reaches the Colorado in 11.3 kilometers, can be seen dropping into the canyon over Plateau Point at bottom center. The blue and black areas on the North Rim indicate a forest fire that was smoldering as the data were acquired on May 12, 2000.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager.

    To assess the potential for an epizootic of pneumonia to result from either natural immigration or translocation, we compared the seroprevalence to Mycoplasma ovipneumoniae in several populations of desert bighorn sheep in Arizona. We collected blood samples and nasal or oropharyngeal swabs from 124 desert bighorn sheep (Ovis canadensis nelsoni) from 6 populations in Arizona in 2009 and 2010. M. ovipneumoniae organisms were detected by PCR in 22%, whereas antibodies to M. ovipneumoniae were detected in 47% of tested bighorn sheep. Mycoplasma antibodies were not found in 2 of 6 populations, indicating some bighorn sheep populations in Arizona are naïve to this bacterium. In contrast, others had seroprevalence rates up to 80%. We were able to compare seroprevalence rates and titers over time in 9 individuals (7 individuals included in the 124 bighorn sheep sampled in 2009 and 2010, and 2 individuals originally captured in 2006). Antibody titers persisted for 12 months in individuals from the Kofa National Wildlife Refuge (n = 7) while antibody titers appeared to decline in the Kanab Creek population (n = 2). M. ovipneumoniae is present or has been present in several, but not all, populations of bighorn sheep in Arizona. The results demonstrate the importance of routine health testing for future translocation efforts to reduce disease risk for naive populations.

    Ortega-Beltran, Alejandro; Jaime, Ramon; Cotty, Peter J

    2015-04-01

    Aflatoxins, highly toxic carcinogens produced by several members of Aspergillus section Flavi, contaminate crops in temperate zones. In the state of Sonora, Mexico, maize is cultivated from 0 to 2100 masl with diverse cultivation practices. This is typical of the nation. In order to design better sampling strategies across Mexico, aflatoxin-producing fungal communities associated with maize production during 2006, 2007, and 2008 in Sonora were investigated in four agro-ecological zones (AEZ) at varying elevation. Fungal communities were dominated by the Aspergillus flavus L strain morphotype (46%), but variation occurred between years and among AEZ. Several atoxigenic isolates with potential to be used as biocontrol agents for aflatoxin mitigation were detected in all AEZ. The characteristics of each AEZ had minimal influences on fungal community structure and should not be a major consideration for future sampling designs for Mexico. Insights into the dynamics and stability of aflatoxin-producing fungal communities across AEZ are discussed. Published by Elsevier Ltd.

  6. How Arizona Medicaid Accelerated the Integration of Physical and Behavioral Health Services.

    Science.gov (United States)

    Bachrach, Deborah; Boozang, Patricia M; Davis, Hailey E

    2017-05-01

    ISSUE: In most states, one agency has responsibility for Medicaid enrollees' physical health services and at least one other agency has responsibility for their behavioral health services. Apportioning responsibility for the physical and behavioral health of Medicaid beneficiaries into different agencies inevitably leads to different--and sometimes misaligned--policy goals, program priorities, and purchasing strategies, thereby impeding the delivery of integrated care. GOAL: To describe the rationale, process, and impact of Arizona's 2015 consolidation of its physical and behavioral health services agencies into its Medicaid agency. METHOD: The study is based on published research, Arizona Medicaid agency materials, and interviews with 34 individuals, including representatives from the current Medicaid agency and previous behavioral health services agency, health plans, primary care and behavioral health providers, consumers, the justice system, and the health information exchange. FINDINGS AND CONCLUSIONS: Consolidation has led to increased attention to behavioral health services and behavioral and physical health integration, enabled more strategic purchasing and streamlined regulatory processes, and enhanced communication, collaboration, and mutual trust across sectors. Arizona’s experience offers lessons to policymakers as they consider how best to integrate physical and behavioral health services and ensure that Medicaid is an efficient and effective purchaser of health care services.

  7. The conservation nexus: valuing interdependent water and energy savings in Arizona.

    Science.gov (United States)

    Bartos, Matthew D; Chester, Mikhail V

    2014-02-18

    Water and energy resources are intrinsically linked, yet they are managed separately--even in the water-scarce American southwest. This study develops a spatially explicit model of water-energy interdependencies in Arizona and assesses the potential for cobeneficial conservation programs. The interdependent benefits of investments in eight conservation strategies are assessed within the context of legislated renewable energy portfolio and energy efficiency standards. The cobenefits of conservation are found to be significant. Water conservation policies have the potential to reduce statewide electricity demand by 0.82-3.1%, satisfying 4.1-16% of the state's mandated energy-efficiency standard. Adoption of energy-efficiency measures and renewable generation portfolios can reduce nonagricultural water demand by 1.9-15%. These conservation cobenefits are typically not included in conservation plans or benefit-cost analyses. Many cobenefits offer negative costs of saved water and energy, indicating that these measures provide water and energy savings at no net cost. Because ranges of costs and savings for water-energy conservation measures are somewhat uncertain, future studies should investigate the cobenefits of individual conservation strategies in detail. Although this study focuses on Arizona, the analysis can be extended elsewhere as renewable portfolio and energy efficiency standards become more common nationally and internationally.

  11. Investigation of the geology and hydrology of the Mogollon Highlands of central Arizona: a project of the Arizona Rural Watershed Initiative

    Parker, John T.C.; Flynn, Marilyn E.

    2000-01-01

    The Mogollon Highlands of east central Arizona is a region of forested plateau and mountains, deep, sheerwalled canyons, and desert valleys. Known for its scenic beauty and characterized by a generally mild climate, the area, though still sparsely populated, attracts an increasing number of tourists and summer residents. Furthermore, the permanent population is expected to nearly double over the next 50 years. Consequently, there is increased pressure on the water resources of this area for several sometimes conflicting uses. Rational management of water resources is necessary to meet increased domestic requirements while ensuring an adequate supply of water for commercial and agricultural use, for Indian lands, and for preservation of valued environmental elements, including surface waters, riparian woodlands, forest and grassland areas, and wildlife and aquatic habitat. Such management requires an understanding of the relations among different components of the hydrologic system—recharge areas, surface flows, shallow aquifers, deep aquifers, discharge areas, and the regional ground-water flow system—and how each is affected by geology, climate, topography, and human use. The U.S. Geological Survey (USGS) is conducting an assessment of the hydrogeology of the Mogollon Highlands in cooperation with the Arizona Department of Water Resources. The study, funded through the State’s Rural Watershed Initiative program, is one of three assessments being conducted by the USGS. Assessments also are underway in the Upper-Middle Verde River watershed and on the Coconino Plateau. Each study has as its objectives: (1) the collection, compilation, and evaluation of all existing geologic, hydrologic, and related data pertaining to the study area and the creation of a data base that is readily accessible to the public and (2) developing an understanding of the hydrogeologic framework, which is the relation between geologic and hydrologic properties, that can be used for

    2002-01-01

    The water resources of the Coconino Plateau in northern Arizona are under increasing demand as a result of development. The population of this arid region continues to grow, and the number of visitors to the many national and state parks and monuments in the region has increased annually. The sustainability, protection, and maintenance of springs and seeps and associated riparian habitat on the Coconino Plateau are major issues that have broad public and governmental support. Regional stakeholders agree that an improved understanding of the regional hydrogeologic system is needed to address the concerns of water supply and ground-water sustainability. The base of information required to adequately describe the hydrogeology of the Coconino Plateau currently does not exist. Hydrogeologic data is most abundant for large population centers like Flagstaff and Sedona, but is sparse for less populated areas like Williams, Tusayan, Valle, and Cameron. There are still large parts of the Coconino Plateau for which there is no basic geologic or hydrologic information available. In order to develop a hydrogeologic framework for the Coconino Plateau, a comprehensive effort is needs to compile existent data and collect additional data to fill in data gaps and reinforce limited information. In 1999, the U.S. Geological Survey (USGS) began an assessment of the hydrogeology of the Coconino Plateau in cooperation with the Arizona Department of Water Resources (ADWR) as part of the Rural Watershed Initiative, a program established by the State of Arizona and managed by the ADWR. Assessments also are underway in the upper-middle Verde River watershed (Woodhouse and others, 2002) to the south and in the Mogollon Highlands to the southeast (Parker and Flynn, 2000). Each study has as its objectives: (1) the collection, compilation, and evaluation of all existing geologic, hydrologic, and related data pertaining to the study area and the creation of a database that is readily accessible

    The upper and middle Verde River watershed in west-central Arizona is an area rich in natural beauty and cultural history and is an increasingly popular destination for tourists, recreationists, and permanent residents seeking its temperate climate. The diverse terrain of the region includes broad desert valleys, upland plains, forested mountain ranges, narrow canyons, and riparian areas along perennial stream reaches. The area is predominantly in Yavapai County, which in 1999 was the fastest-growing rural county in the United States (Woods and Poole Economics, Inc., 1999); by 2050, the population is projected to more than double. Such growth will increase demands on water resources. The domestic, industrial, and recreational interests of the population will need to be balanced against protection of riparian, woodland, and other natural areas and their associated wildlife and aquatic habitats. Sound management decisions will be required that are based on an understanding of the interactions between local and regional aquifers, surface-water bodies, and recharge and discharge areas. This understanding must include the influence of climate, geology, topography, and cultural development on those components of the hydrologic system. In 1999, the U.S. Geological Survey (USGS), in cooperation with the Arizona Department of Water Resources (ADWR), initiated a regional investigation of the hydrogeology of the upper and middle Verde River watershed. The project is part of the Rural Watershed Initiative (RWI), a program established by the State of Arizona and managed by the ADWR that addresses water supply issues in rural areas while encouraging participation from stakeholder groups in affected communities. The USGS is performing similar RWI investigations on the Colorado Plateau to the north and in the Mogollon Highlands to the east of the Verde River study area (Parker and Flynn, 2000). The objectives of the RWI investigations are to develop: (1) a single database

    LOCATION OF AREAThe San Franciscan volcanic field, which takes its name from San Francisco Mountain, the largest volcano of the group, covers about 3,000 square miles in the north-central part of Arizona, as shown by the shaded space on the index map forming figure 1. The center of the field lies about 50 miles south of the Grand Canyon of the Colorado and the southern boundary is in part coterminous with that of the San Francisco Plateau, which forms the southwestern division of the great Colorado Plateau.The region is easily reached, for the main line of the Atchison, Topeka, & Santa Fe Railway traverses it from east to west for more than 60 miles. Flagstaff, a town of 1,500 inhabitants 10 miles south of the summit of San Francisco Mountain, is on the railroad, amid a branch line runs from Williams, 34 miles farther west, to the Grand Canyon. All the more important points of interest in the field may be reached without difficulty by wagon, and outfits may be obtained at Flagstaff.OUTLINE OF THE REPORTThis report deals primarily with the volcanic phenomena of the region as determined in the field and laboratory. Chapter I contains a brief description of the geography of the field and Chapter II is devoted largely to the sedimentary formations and structure. The rest of the report Chapters III to VI—treats entirely of the various features of the volcanoes and igneous rocks, both individually and collectively. Detailed descriptions of the volcanoes and lava fields are given in Chapter III; the volcanic history of the region and its correlation with the general history of the surrounding country are presented in Chapter IV. These two chapters will presumably suffice for the general reader who may desire to become acquainted with the broader volcanic features of the region. Chapter V (Petrography) is devoted entirely to the detailed description of the individual igneous rocks of the region, as represented by a selected set of type specimens. In Chapter VI (Petrology

    Climate is commonly assumed to be an important factor influencing weathering, erosion and landscape evolution, but few studies have quantitatively assessed differences in geomorphology associated with minor but persistently different moisture and temperature conditions. In northeastern Arizona, we have studied several small ( ˜0.5 km2), semi-arid eastward-draining basins where topography has induced different microclimates on north- and south-facing canyon slopes. These 60-100 m deep canyons expose lenticular silty sandstones and mudstones of the Jurassic Morrison formation; sandstones, shales, and coals of the Cretaceous Dakota formation; and shales of the Mancos formation. Over one annual cycle (beginning 17 August 2002), we monitored air, surface, and subsurface temperatures as well as soil moisture at four locations at 0.5 h intervals. The annual average air temperature (at ˜10 cm above the surface) was 1.3° C warmer on a south-facing colluvial slope and 2.1° C warmer on a south-facing exposure of weathered sandstone than on north-facing slopes of the same type. Annual average surface temperature was 3.0-3.8° C warmer on south-facing slopes and the temperature at ˜10 cm depth in the sandstone was 5.7° C warmer on the south-facing slope. Soil moisture tension averaged at least 78-100 kPa lower on north-facing slopes at 10 cm depth but only 36 kPa lower at 30 cm depth. Morrison formation sandstones weather primarily by granular disintegration and form a disaggregated mantle on some slopes where weathering exceeds erosion, but also form little-weathered vertical cliffs (dominantly on southerly aspects). Rock strength was estimated at over 400 sites using a Schmidt hammer. Slope angle and aspect, as well as vegetation type and % cover were also recorded at each location. Vegetation covers about 4 times as much area on northeast-facing slopes as on southwest facing slopes. Young's modulus values derived from Schmidt hammer rebound for southwest-facing points

    The annual Flagstaff Festival of Science, established in 1990, is the longest running, entirely free, public science festival in the USA. It has evolved into a 10-day-long festival with >90 events, including interactive science and technology exhibits, daily public lectures, open houses, star parties, local field trips, and an in-school speaker program. The Festival events reach an estimated 17,000 people every year in Northern Arizona, including students from pre-K through college, parents, teachers, tourists, and lifelong learners. Flagstaff, AZ, "America's First STEM Community" and the "World's First International Dark Sky City," has a uniquely rich community of organizations engaged in science and engineering research and innovation, including the Flagstaff Arboretum, Flagstaff Dark Skies Coalition, Coconino Community College, W. L. Gore & Associates, Lowell Observatory, Museum of Northern Arizona, National Weather Service, National Park Service, National Forest Service, Northern Arizona University, Northern Arizona Center for Entrepreneurship and Technology, U.S. Geological Survey, U.S. Naval Observatory, and Willow Bend Environmental Education Center. As such, the Festival has tremendous support from the local community, which is evidenced by its financial support (via grants and donations), attendance, and awards it has received. Public STEM events are an increasingly popular way for scientists to reach underserved populations, and the Flagstaff Festival of Science provides local scientists and other research professionals with many diverse opportunities to foster public support of science and inspire students to study STEM disciplines. The goal of this presentation is to share information, ideas, and our experiences with anyone wishing to initiate or expand his or her current public STEM offerings; and to celebrate the rewards (for both learners and research professionals) of engaging in science education and communication at public STEM events.

    Cruikshank, Dale P.; Hartmann, William K.

    2014-11-01

    The roots of the Lunar and Planetary Laboratory (LPL) extend deep into the rich fabric of G. P. Kuiper’s view of the Earth as a planet and planetary systems as expected companions to most stars, as well as the post-war emergent technology of infrared detectors suitable for astronomy. These concepts and events began with Kuiper’s theoretical work at Yerkes Observatory on the origin of the Solar System, his discovery of two planetary satellites and observational work with his near-infrared spectrometer on the then-new McDonald 82-inch telescope in the mid- to late-1940s. A grant for the production of a photographic atlas of the Moon in the mid-1950s enabled him to assemble the best existing images of the Moon and acquire new photographs. This brought E. A. Whitaker and D. W. G. Arthur to Yerkes. Others who joined in the lunar work were geologist Carl S. Huzzen and grad student E. P. Moore, as well as undergrad summer students A. B. Binder and D. P. Cruikshank (both in 1958). The Atlas was published in 1959, and work began on an orthographic lunar atlas. Kuiper’s view of planetary science as an interdisciplinary enterprise encompassing astronomy, geology, and atmospheric physics inspired his vision of a research institution and an academic curriculum tuned to the combination of all the scientific disciplines embraced in a comprehensive study of the planets. Arrangements were made with the University of Arizona (UA) to establish LPL in affiliation with the widely recognized Inst. of Atmospheric Physics. Kuiper moved to the UA in late 1960, taking the lunar experts, graduate student T. C. Owen (planetary atmospheres), and associate B. M. Middlehurst along. G. van Biesbroeck also joined the migration to Tucson; Binder and Cruikshank followed along as new grad students. Astronomy grad student W. K. Hartmann came into the academic program at UA and the research group at LPL in 1961. Senior faculty affiliating with LPL in the earliest years were T. Gehrels, A. B

As mais recentes propagações musicais, que se atrelam à linguagem audiovisual, marcam a paisagem dos lugares, que comunica, retrata, e possibilita a existência de distintas territorialidades no espaço. O presente artigo objetiva tecer relações entre a paisagem sonora e a construção de multiterritorialidades, a partir de exemplos de identidades criadas com base em movimentos e estilos musicais, seus territórios e territorialidades. Abstract DRUMS, RADIOS AND VIDEO-CLIPS: ABOUT SOUNDSCAPES, TERRITORIES AND MULTITERRITORIALITIES The sounds transmitted through vibrations in air are produced in different forms and ways, by nature or by human beings. Many sounds exist in the nature like wind sounds, water sounds and animal sounds. The humans produced sounds like speech, work sounds, musics and others. Therefore, they can organize sounds to communicate and nowadays they found out the possibility of the keep sounds to reproduce it in differents places. The humanity communicate ideas and cultural values through the speech or music. The most recent spread musics that are related with audiovisual language showed the landscapes of places and it also communicate, reflect and gives rise distinct territorialities space.

    Dixon, William Jesse J.

    This thesis addresses the issue of making an economic case for bulk energy storage in the Arizona bulk power system. Pumped hydro energy storage (PHES) is used in this study. Bulk energy storage has often been suggested for large scale electric power systems in order to levelize load (store energy when it is inexpensive [energy demand is low] and discharge energy when it is expensive [energy demand is high]). It also has the potential to provide opportunities to avoid transmission and generation expansion, and provide for generation reserve margins. As the level of renewable energy resources increases, the uncertainty and variability of wind and solar resources may be improved by bulk energy storage technologies. For this study, the MATLab software platform is used, a mathematical based modeling language, optimization solvers (specifically Gurobi), and a power flow solver (PowerWorld) are used to simulate an economic dispatch problem that includes energy storage and transmission losses. A program is created which utilizes quadratic programming to analyze various cases using a 2010 summer peak load from the Arizona portion of the Western Electricity Coordinating Council (WECC) system. Actual data from industry are used in this test bed. In this thesis, the full capabilities of Gurobi are not utilized (e.g., integer variables, binary variables). However, the formulation shown here does create a platform such that future, more sophisticated modeling may readily be incorporated. The developed software is used to assess the Arizona test bed with a low level of energy storage to study how the storage power limit effects several optimization outputs such as the system wide operating costs. Large levels of energy storage are then added to see how high level energy storage affects peak shaving, load factor, and other system applications. Finally, various constraint relaxations are made to analyze why the applications tested eventually approach a constant value. This

  4. Age and diet of fossil California condors in Grand Canyon, Arizona

    1987-08-14

    A dozen new radiocarbon dates, together with a thorough review of its fossil distribution, shed new light on the time and probable cause of extinction of the California condor, Gymnogyps californianus, in Grand Canyon, Arizona. The radiocarbon data indicate that this species became extinct in Grand Canyon, and other parts of the inland West, more than 10,000 years ago in coincidence with the extinction of megafauna (proboscidians, edentates, perissodactyls). That condors relied on the megafauna for food is suggested by the recovery of food bones from a late Pleistocene nest cave in Grand Canyon. These fossil data have relevance to proposed release and recovery programs of the present endangered population of California condors. 19 references, 1 figure, 2 tables.

  5. Predictive Models of the Hydrological Regime of Unregulated Streams in Arizona

    Three statistical models were developed by the U.S. Geological Survey in cooperation with the Arizona Department of Environmental Quality to improve the predictability of flow occurrence in unregulated streams throughout Arizona. The models can be used to predict the probabilities of the hydrological regime being one of four categories developed by this investigation: perennial, which has streamflow year-round; nearly perennial, which has streamflow 90 to 99.9 percent of the year; weakly perennial, which has streamflow 80 to 90 percent of the year; or nonperennial, which has streamflow less than 80 percent of the year. The models were developed to assist the Arizona Department of Environmental Quality in selecting sites for participation in the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program. One model was developed for each of the three hydrologic provinces in Arizona - the Plateau Uplands, the Central Highlands, and the Basin and Range Lowlands. The models for predicting the hydrological regime were calibrated using statistical methods and explanatory variables of discharge, drainage-area, altitude, and location data for selected U.S. Geological Survey streamflow-gaging stations and a climate index derived from annual precipitation data. Models were calibrated on the basis of streamflow data from 46 stations for the Plateau Uplands province, 82 stations for the Central Highlands province, and 90 stations for the Basin and Range Lowlands province. The models were developed using classification trees that facilitated the analysis of mixed numeric and factor variables. In all three models, a threshold stream discharge was the initial variable to be considered within the classification tree and was the single most important explanatory variable. If a stream discharge value at a station was below the threshold, then the station record was determined as being nonperennial. If, however, the stream discharge was above the threshold

    Coccidioidomycosis is a fungal infection endemic to the southwestern United States, particularly Arizona and California. Its incidence has increased, potentially due in part to the effects of changing climatic variables on fungal growth and spore dissemination. This study aims to quantify the county-level vulnerability to coccidioidomycosis in Arizona and California and to assess the relationships between population vulnerability and climate variability. The variables representing exposure, sensitivity, and adaptive capacity were combined to calculate county level vulnerability indices. Three methods were used: (1) principal components analysis; (2) quartile weighting; and (3) percentile weighting. Two sets of indices, "unsupervised" and "supervised", were created. Each index was correlated with coccidioidomycosis incidence data from 2000-2014. The supervised percentile index had the highest correlation; it was then correlated with variability measures for temperature, precipitation, and drought. The supervised percentile index was significantly correlated ( p vulnerable counties and provides support for the hypothesis that population vulnerability to coccidioidomycosis is associated with climate variability.

  7. Floods of October 1977 in southern Arizona and March 1978 in central Arizona

    Major floods occurred in October 1977 and March 1978 in Arizona. As much as 14 inches of rain fell during October 6-9, 1977, over the mountains of southern Arizona and northern Mexico resulting in the highest discharge since at least 1892 on the Santa Cruz River upstream from Tucson. The flood inundated areas as much as 4 miles wide, covered at least 16,000 acres of farmland, and caused $15.2 million in damage. Residential losses occurred at Nogales, Amado, Green Valley, and Sahuarita. Severe erosional damage occurred along the Santa Cruz River, Agua Fria Canyon, Potrero Creek, and many small drainages in the Sonoita Creek basin. The peak discharge in Agua Fria Canyon was the highest since before 1900. Less severe flooding occurred along the San Pedro River and the Gila River downstream from the San Pedro. Widespread rainfall of 3 to 6 inches and 9 to 14 inches in some areas in the central mountains during February 27 to March 3, 1978, caused the highest discharge since 1920 on the Salt River in Phoenix and resulted in three deaths. Flooding along the Salt and Gila Rivers and several lesser streams caused statewide damage totaling $65.9 million, of which about $37 million occurred in Maricopa County. Nine counties were declared disaster areas. During the flood of March 1978, moderate peak discharges and unusually high volumes of runoff occurred on tributaries to the Salt and Verde Rivers upstream from a system of reservoirs. Flood magnitudes were greater at the main-stem gaging stations than on the tributaries. The peak discharge into Theodore Roosevelt Lake, which was 21 percent full at the start of the flood, was about 155,000 cubic feet per second, the largest known from 1890 to 1978. The reservoirs stored large quantities of water and greatly reduced the magnitude of the flood. The peak discharge of the Salt River was 125,000 cubic feet per second below Granite Reef Dam and 122,000 cubic feet per second at Phoenix. Discharges in excess of 100,000 cubic feet per

    In the present study, the air quality of the city of Hermosillo, Sonora, Mexico was assessed considering total suspended particulates (tsp) and heavy metals (Pb, Cd, Ni, Cu, Cr) from June 2001 through May 2002 in three monitoring sites Centro (Mazon), Nor este (CESUES) and Noroeste (CBTIS). The filter-samples used for that purpose were provided by the Air Quality Evaluation and Improvement Program (PEMCA) of the municipality of Hermosillo. The sampling method was based on high volume sampling frequency set every 6 days with non-simultaneous sampling among the three sampling sites. Filters were dissolved for metal determination by acidic-extraction, and then analyzed by flame atomic absorption spectrophotometry. Results indicate that tsp concentrations at Centro and Noroeste sites were frequently higher than the maximum daily permissible level (260 {mu}g/m{sup 3}), while in the three sites the annual average was higher than the maximum annual permissible level (75 {mu}g/m{sup 3}) both established in the standard NOM-024-Ssa-1993 (Ssa 1994a). According to the Air Quality Standard Index (US EPA 1992a), used in Mexico by Air Quality Metropolitan Index (IMECA) the results indicate that the air quality in the city of Hermosillo regarding tsp was placed between no satisfactory and poor. In regard to heavy metals (Pb, Cd, Ni, Cu, Cr), concentrations detected were below the maximum permissible levels and/or criteria taking into account the standard NOM-026-Ssa-1993 (Ssa 1994b), the Who criterion (2000), the European Union criterion (Cec 2003), and the European Environmental Agency criteria (EEA 2004). Such findings would mean that airborne metals are of no concern; however, air quality is still classified as no satisfactory due to high particulate matter concentrations. Keeping air quality parameters monitoring is recommended in order to get extensive data for use in risk studies of air quality and health (morbidity/mortality), as well as topographic conditions

    2015-08-01

    Full Text Available The Sonora Margin cold seeps present a seafloor mosaic pattern consisting of different faunal assemblages and microbial mats. To better understand if sedimentary microbial communities reflect this patchy distribution, all major habitats were investigated using four complementary approaches: 16S rRNA 454 pyrosequencing, quantitative polymerase chain reaction, fluorescence in situ hybridization and geochemistry analyses. This study reveals that sediments populated by different surface assemblages show distinct porewater geochemistry features and are associated with distinct microbial communities. In the sediments underlying the microbial mat and the surrounding macrofauna, microbial communities were dominated by anaerobic methane oxidizers (archaeal anaerobic methanotroph ANME and sulfate-reducing Deltaproteobacteria. In contrast, sediment-associated microbial communities underlying the megafauna habitats (vesicomyids and siboglinids were characterized by a lower biomass and important proportions of the Marine Benthic Group D (MBG-D, Chloroflexi as well as filamentous Gammaproteobacteria and Deltaproteobacteria. Together, geochemical and microbial surveys indicate that porewater methane concentrations play an important role in the microbial community structure and subsequently in the establishment of the surface colonizers. Furthermore, presence and activity of the surface colonizers influence the underlying microbial communities probably because of modification of energy source availabilities.

    Gastropods are an important component in most of the fossil record; however, investigations have focused mainly on the characterization of the tafofacies and signatures in determined environments. We present qualitative and quantitative taphonomic data for the gastropod cf. Donaldina robusta assemblages from the La Joya Formation of the Sierra Agua Verde, Sonora State, (NW) Mexico. We analyzed 176 shells. Good preservation received ahigh taphonomic grade (A) and poor preservation a D. The shells were complete in 72% of cases (taphonomic grade B). Less than 10% are corroded or are parallel to the layer (grade A). This rock is petrographycally classified as wackestone, sedimentologically it is characterized by middle sorting (grade B) and low grading (grade A). The fossiliferous assemblage grades as A and B. Biostratinomic features of the skeletal assemblage are characteristic of sedimentologic concentrations of autochthonous-parautochthonous elements at the accumulation site. There was minimal reworking and transport in an environment of low energy, locally produced during a short period of accumulation.

    Dengue virus, primarily transmitted by the Aedes aegypti (L.) mosquito, has rapidly expanded in geographic extent over the past several decades. In some areas, however, dengue fever has not emerged despite established Ae. aegypti populations. The reasons for this are unclear and have sometimes been attributed to socio-economic differences. In 2013 we compared Ae. aegypti adult density and population age structure between two cities in Sonora, Mexico: Hermosillo, which has regular seasonal dengue virus transmission, and Nogales, which has minimal transmission. Larval and pupal abundance was greater in Nogales, and adult density was only higher in Hermosillo during September. Population age structure, however, was consistently older in Hermosillo. This difference in longevity may have been one factor that limited dengue virus transmission in Nogales in 2013, as a smaller proportion of Ae. aegypti females survived past the extrinsic incubation period. © The Authors 2016.

Las plantas en ambas poblaciones son diploides (2n= 2x= 60. El contenido promedio 2C de ADN nuclear fue de 8.404 pg; 1Cx= 4 120 millones de pares de nucleótidos. El cariotipo bimodal fue similar en las 2 poblaciones y consistió de 10 cromosomas grandes y 50 pequeños y correspondió a 46m+6st+8t: también mostró un par de cromosomas telocéntricos grandes con constricción secundaria. El cociente de los brazos cromosómicos fue diferente en los pares 7, 8, 14 y 16 del grupo de cromosomas pequeños que presentan diferencias morfológicas entre las 2 poblaciones. Estos rearreglos cromosómicos podrían deberse a intercambios cromosómicos heterocigóticos espontáneos y son evidencia de que los genomas de distintas poblaciones de A. aktites se encuentran en un activo proceso de diferenciación que podría llevar a la especiación. Los análisis son básicos para conocer la diversidad genética intraespecífica de A. aktites y para establecer estrategias de conservación in situ y ex situ para esta especie.Genome size and karyotype structure of 2 wild populations of Agave aktites Gentry from Las Bocas and San Carlos, Sonora, Mexico were determined.

    Rural children consume more calories per day on average than urban children, and they are less likely to consume fruit. Self-service salad bars have been proposed as an effective approach to better meet the National School Lunch Program's fruit and vegetable recommendations. No studies have examined how rural and urban schools differ in the implementation of school salad bars. To compare the prevalence of school-lunch salad bars and differences in implementation between urban and rural Arizona schools. Secondary analysis of a cross-sectional web-based survey. School nutrition managers (N=596) in the state of Arizona. National Center for Education Statistics locale codes defined rural and urban classifications. Barriers to salad bar implementation were examined among schools that have never had, once had, and currently have a school salad bar. Promotional practices were examined among schools that once had and currently have a school salad bar. Generalized estimating equation models were used to compare urban and rural differences in presence and implementation of salad bars, adjusting for school-level demographics and the clustering of schools within districts. After adjustment, the prevalence of salad bars did not differ between urban and rural schools (46.9%±4.3% vs 46.8%±8.5%, respectively). Rural schools without salad bars more often reported perceived food waste and cost of produce as barriers to implementing salad bars, and funding was a necessary resource for offering a salad bar in the future, as compared with urban schools (P<0.05). No other geographic differences were observed in reported salad bar promotion, challenges, or resources among schools that currently have or once had a salad bar. After adjustment, salad bar prevalence, implementation practices, and concerns are similar across geographic settings. Future research is needed to investigate methods to address cost and food waste concerns in rural areas. Copyright © 2017 Academy of Nutrition and

    Beaudette, D. E.; O'Geen, A. T.

    2009-10-01

    Digital soil survey products represent one of the largest and most comprehensive inventories of soils information currently available. The complex structure of these databases, intensive use of codes and scientific jargon make it difficult for non-specialists to utilize digital soil survey resources. A project was initiated to construct a web-based interface to digital soil survey products (STATSGO and SSURGO) for California, Arizona, and Nevada that would be accessible to the general public. A collection of mature, open source applications (including Mapserver, PostGIS and Apache Web Server) were used as a framework to support data storage, querying, map composition, data presentation, and contextual links to related materials. Application logic was written in the PHP language to "glue" together the many components of an online soil survey. A comprehensive website ( http://casoilresource.lawr.ucdavis.edu/map) was created to facilitate access to digital soil survey databases through several interfaces including: interactive map, Google Earth and HTTP-based application programming interface (API). Each soil polygon is linked to a map unit summary page, which includes links to soil component summary pages. The most commonly used soil properties, land interpretations and ratings are presented. Graphical and tabular summaries of soil profile information are dynamically created, and aid with rapid assessment of key soil properties. Quick links to official series descriptions (OSD) and other such information are presented. All terminology is linked back to the USDA-NRCS Soil Survey Handbook which contains extended definitions. The Google Earth interface to Soil-Web can be used to explore soils information in three dimensions. A flexible web API was implemented to allow advanced users of soils information to access our website via simple web page requests. Soil-Web has been successfully used in soil science curriculum, outreach activities, and current research projects

  1. Influence of Tree-Scale Environmental Variability on Tree-Ring Reconstructions of Temperature at Sonora Pass, CA

    Science.gov (United States)

    Ma, L.; Stine, A.

    2016-12-01

    Tree-ring width from treeline environments tend to covary with local interannual temperature variabilities. However, other environmental factors such as moisture and light availability may further modulate tree growth in cold climates. We investigate the influence of various environmental factors on a tree-ring record from a research plot near Sonora Pass, CA (38.32N, 119.64W; elev. 3130 m). This treeline ecotone is dominated by whitebark pine (Pinus albicaulis) growing as individuals and as stands, and at the transition between tree form and krummholtz. We surveyed all trees in the 160m x 90m site, mapping and coring all trees with a diameter at breast height greater than 10 cm. We use survey data to test for an influence of inter-tree competition on growth. We also test for modulation of growth by variation in distance from surface water, aspect and slope, and soil types. Initial result shows a relationship between tree ring width and local May-July temperature (R = 0.33, p effect of spatial variability on mean growth rate and on reconstructed temperatures. Trees that have larger or closer neighboring trees experience greater competition, and we hypothesize that competition will be inversely related to average growth rate. Further, we test the sensitivity of ring-width interannual variability to other non-temperature environmental drivers such as moisture availability, light competition, and spatial relations in the microenvironment. We hypothesize that trees that have ready access to light and water will likely produce ring records more closely correlated with the temperature record, and thus will produce a temperature reconstruction with a higher signal-to-noise ratio; whereas trees that experience more microenvironment limitations or competition will produce ring records resembling temperature and additional environmental factors or will contain more noise.

  2. Testing for the Influence of Light Availability on Tree-Ring Reconstructed Temperature at Sonora Pass, CA

    Ma, L.; Stine, A.

    2015-12-01

    Tree-ring width and density near treeline tend to covary with local interannual temperature, motivating the use of such records to reconstruct past temperature variability. However, recent work has introduced the possibility of multiple environmental factors contributing to tree growth in cold environments. We investigate the influence of small-scale light variability on tree-ring based temperature reconstructions from a treeline ecotone. We establish an experimental plot near Sonora Pass in the California Sierra Nevada (38.32N, 119.64W; elev. 3130 m). This treeline environment is dominated by whitebark pine (Pinus albicaulis) growing as individuals and in stands, providing an opportunity to test the sensitivity of mean growth rate and interannual variability to light availability. For each tree we quantify the local light environment using three approaches: (i.) geometrical estimates of shading from neighboring trees, (ii.) photographic estimates of shading from neighboring trees, and (iii.) geometric estimates of direct light availability resulting from aspect and local topography. Geometrical estimates of shading are made by mapping the relative position and crown dimensions of each tree in the plot in order to calculate a shading index that will be used to test hypotheses about the influence of shading on tree growth. Photographic estimates of tree-level shading are created by taking hemispheric photographs at the crown edge of each tree and calculating the effects of neighboring trees on direct and diffuse light availability using the Gap Light Analyzer software. To quantify tree growth, increment cores are collected from all trees in the plot to develop sub-chronologies of ring records grouped by different light environments. We hypothesize that trees growing in open areas or at edge of stands, which experience little inter-tree competition, would likely produce ring records more closely correlated with the temperature record; whereas trees growing in middle

  3. The migration response to the Legal Arizona Workers Act.

    2014-08-01

    The 2008 Legal Arizona Workers Act (LAWA) requires all public and private employers to authenticate the legal status of their workers using the federal employment verification system known as E-Verify. With LAWA, Arizona became the first state to have a universal mandate for employment verification. While LAWA targets unauthorized workers, most of whom are Latino immigrants, other groups could experience LAWA's effects, such as those who share households with undocumented workers. In addition, employers may seek to minimize their risk of LAWA penalties by not hiring those who appear to them as more likely to be unauthorized, such as naturalized Latino immigrants and US-born Latinos. Existing research has found a reduction in foreign-born Latino employment and population in response to LAWA. This paper asks a different question: have groups that are most likely to be affected by the law migrated to other states? We find a significant and sustained increase in the internal outmigration rate from Arizona of foreign-born, noncitizen Latinos - the group most likely to include the unauthorized - after the passage of LAWA. There was no significant LAWA internal migration response by foreign-born Latino citizens. US-born Latinos showed some signs of a LAWA-induced internal migration response after the law went into effect, but it is not sustained. The results indicate that local and state immigration policy can alter the settlement geography of the foreign born. This leads us to speculate about how immigrant settlement may adjust in the coming years to the intersecting geographies of post-recession economic opportunity and tiered immigration policies.

    The University of Arizona’s Astronomy Club utilizes its access to the many telescopes in and around Tucson, Arizona, to allow students to fully participate in a variety of research projects. Three current projects - the exoplanet project, the radio astronomy project, and the Kepler project - all work to give undergraduates who are interested in astronomy the opportunity to explore practical astronomy outside the classroom and in a peer-supported environment. The exoplanet project strives to teach students about the research process, including observing exoplanet transits on the Steward Observatory 61” Kuiper telescope on Mt. Bigelow in Tucson, AZ, reducing the data into lightcurves with the Image Reduction and Analysis Facility (IRAF), modeling the lightcurves using the Interactive Data Language (IDL), and writing and publishing a professional paper, and does it all with no faculty involvement. The radio astronomy project is designed to provide students with an opportunity to work with a professor on a radio astronomy research project, and to learn about the research process, including observing molecules in molecular clouds using the Arizona Radio Observatory 12-meter radio telescope on Kitt Peak in Arizona. The Kepler project is a new project designed in part to facilitate graduate-undergraduate interaction in the Astronomy Department, and in part to allow students (both graduate and undergraduate) to participate in star-spot cycle research using data from the Kepler Mission. All of these research projects and structures provide students with unique access to telescopes, peer mentoring, networking, and understanding the entire process of astronomical research.

  19. Seismic scanning tunneling macroscope - Elastic simulations and Arizona mine test

    KAUST Repository

    Hanafy, Sherif M.

    2012-01-01

    Elastic seismic simulations and field data tests are used to validate the theory of a seismic scanning tunneling macroscope (SSTM). For nearfield elastic simulation, the SSTM results show superresolution to be better than λ/8 if the only scattered data are used as input data. If the direct P and S waves are muted then the resolution of the scatterer locations are within about λ/5. Seismic data collected in an Arizona tunnel showed a superresolution limit of at least λ/19. These test results are consistent with the theory of the SSTM and suggest that the SSTM can be a tool used by geophysicists as a probe for near-field scatterers.

    The Arizona Sky Island Arthropod Project (ASAP) is a new multi-disciplinary research program at the University of Arizona that combines systematics, biogeography, ecology, and population genetics to study origins and patterns of arthropod diversity along elevation gradients and among mountain ranges in the Madrean Sky Island Region. Arthropods represent taxonomically and ecologically diverse organisms that drive key ecosystem processes in this mountain archipelago. Using data from museum specimens and specimens we obtain during long-term collecting and monitoring programs, ASAP will document arthropod species across Arizona's Sky Islands to address a number of fundamental questions about arthropods of this region. Baseline data will be used to determine climatic boundaries for target species, which will then be integrated with climatological models to predict future changes in arthropod communities and distributions in the wake of rapid climate change. ASAP also makes use of the natural laboratory provided by the Sky Islands to investigate ecological and genetic factors that influence diversification and patterns of community assembly. Here, we introduce the project, outline overarching goals, and describe preliminary data from the first year of sampling ground-dwelling beetles and ants in the Santa Catalina Mountains.

ASAP also makes use of the natural laboratory provided by the Sky Islands to investigate ecological and genetic factors that influence diversification and patterns of community assembly. Here, we introduce the project, outline overarching goals, and describe preliminary data from the first year of sampling ground-dwelling beetles and ants in the Santa Catalina Mountains.

    Executive Summary: Arizona is located in an arid to semiarid region in the southwestern United States and is one of the fastest growing States in the country. Population in Arizona surpassed 6.5 million people in 2008, an increase of 140 percent since 1980, when the last regional U.S. Geological Survey (USGS) groundwater study was done as part of the Regional Aquifer System Analysis (RASA) program. The alluvial basins of Arizona are part of the Basin and Range Physiographic Province and cover more than 73,000 mi2, 65 percent of the State's total land area. More than 85 percent of the State's population resides within this area, accounting for more than 95 percent of the State's groundwater use. Groundwater supplies in the area are expected to undergo further stress as an increasing population vies with the State's important agricultural sector for access to these limited resources. To provide updated information to stakeholders addressing issues surrounding limited groundwater supplies and projected increases in groundwater use, the USGS Groundwater Resources Program instituted the Southwest Alluvial Basins Groundwater Availability and Use Pilot Program to evaluate the availability of groundwater resources in the alluvial basins of Arizona. The principal products of this evaluation of groundwater resources are updated groundwater budget information for the study area and a proof-of-concept groundwater-flow model incorporating several interconnected groundwater basins. This effort builds on previous research on the assessment and mapping of groundwater conditions in the alluvial basins of Arizona, also supported by the USGS Groundwater Resources Program. Regional Groundwater Budget: The Southwest Alluvial Basins-Regional Aquifer System Analysis (SWAB-RASA) study produced semiquantitative groundwater budgets for each of the alluvial basins in the SWAB-RASA study area. The pilot program documented in this report developed new quantitative estimates of groundwater

    Full Text Available This article reports the results of a survey of third-grade teachers of English Language Learners (ELLs in Arizona regarding school language and accountability policies—Proposition 203, which restricts bilingual education and mandates sheltered English Immersion; the federal No Child Left Behind Act of 2001 (NCLB; and Arizona LEARNS, the state’s high-stakes testing and accountability program. The instrument, consisting of 126 survey questions plus open-ended interview question, was designed to obtain teacher’s views, to ascertain the impact of these polices, and to explore their effectiveness in improving the education of ELL students. The survey was administered via telephone to 40 teacher participants from different urban, rural and reservation schools across the state. Each participant represents the elementary school in their respective school district which has the largest population of ELL students. Analyses of both quantitative and qualitative data reveal that these policies have mostly resulted in confusion in schools throughout the state over what is and is not allowed, and what constitutes quality instruction for ELLs, that there is little evidence that such policies have led to improvements in the education of ELL students, and that these policies may be causing more harm than good. Specifically, teachers report they have been given little to no guidance over what constitutes sheltered English immersion, and provide evidence that most ELL students in their schools are receiving mainstream sink-or-swim instruction. In terms of accountability, while the overwhelming majority of teachers support the general principle, they believe that high-stakes tests are inappropriate for ELLs and participants provided evidence that the focus on testing is leading to instruction practices for ELLs which fail to meet their unique linguistic and academic needs. The article concludes with suggestions for needed changes to improve the quality of

    We used a new data set of relocated earthquakes recorded by the Seismic Network of Northeastern Sonora, Mexico (RESNES) to characterize the attenuation of S-waves in the fault zone of the 1887 Sonora earthquake (M w 7.5). We determined spectral attenuation functions for hypocentral distances (r) between 10 and 140 km using a nonparametric approach and found that in this fault zone the spectral amplitudes decay slower with distance at low frequencies (f attenuation functions obtained for 23 frequencies (0.4 ≤ f ≤ 63.1 Hz) permit us estimating the average quality factor Q S  = (141 ± 1.1 )f ((0.74 ± 0.04)) and a geometrical spreading term G(r) = 1/r (0.21). The values of Q estimated for S-wave paths traveling along the fault system that rupture during the 1887 event, in the north-south direction, are considerably lower than the average Q estimated using source-station paths from multiple stations and directions. These results indicate that near the fault zone S waves attenuate considerably more than at regional scale, particularly at low frequencies. This may be the result of strong scattering near the faults due to the fractured upper crust and higher intrinsic attenuation due to stress concentration near the faults.

    Full Text Available En el bioma americano Desierto de Sonora existe una subregión conocida como “Planicies de Sonora”, con vegetación desértica pero suficientemente nutritiva para albergar fauna silvestre mayor, como venado, berrendo y borrego cimarrón. No obstante esta vocación, desde su colonización se dedicó a la ganadería extensiva de agostadero, actividad económica que caracteriza al estado de Sonora. Este paisaje conformó una cultura vaquera con rasgos distintivos propios que formaron identi- dades auténticas en la región. En el 2000 un cambio en la legislación ambiental, que antes prohibía la cacería con fines comerciales y ahora específicamente la permite e incentiva, está transformando el modelo simbólico de esta región, así como los roles y las identidades sociales y subjetivas que prevalecieron por más de un siglo.

    Full Text Available Mientras que, para principios de la década de 1850, la atención del mundo entero se enfocaba en los campos auríferos en California, ocurría un movimiento semejante, aunque de proporciones menores, con respecto al territorio de Altar en el norte de Sonora. El artículo comienza con una breve descripción de los intentos de explotar los depósitos de oro y plata en la región durante el virreinato, así como su papel en la creación de ciertos mitos y leyendas referentes a la gran riqueza que supuestamente existía debajo del subsuelo sonorense. Se examina en particular, la expedición procedente de California que penetró a la zona en la primavera de 1851 en busca de oro, y que constituyó un antecedente importante relativo a las expediciones filibusteras encabezadas por Joseph Morehead, Charles de Pindray y otros aventureros extranjeros a lo largo de los cincuenta. El artículo concluye con una evaluación del significado de la fiebre del oro de este periodo con referencia al desarrollo posterior del noroeste de Sonora, y de la integración del estado a los mercados comerciales de Estados Unidos y de otras regiones de México.

    Full Text Available En México el pasado arqueológico es significativo, pese a que no todas las ruinas son valoradas equitativamente. Se piensa que la arqueología existe donde hay pirámides, y se considera que en su ausencia no hay arqueología. En la zona maya de Mesoamérica prevalece la primera idea, mientras que en Sonora predomina la segunda. En este artículo se pretende demostrar que la valoración desigual de la arqueología es el resultado de varios factores, entre los que se distinguen el nacionalismo y el turismo. Aquí se realiza una comparación de áreas cultural y geográficamente diferentes: el sitio maya de Tulum, en Quintana Roo, y el Cerro de Trincheras, en Sonora. Para el análisis se utiliza la cuarta emisión de billetes del Banco de México, así como folletos de viaje para promoción turística, producidos por la Secretaría de Turismo. La simplicidad de la frase en el norte no hay arqueología permite, en realidad, comprender el éxito selectivo del manejo del pasado prehispánico que ha tenido la clase dirigente. Se concluye que la arqueología ha sido un proyecto paralelo del nacionalismo y turismo posrevolucionarios.

    We documented puma (Puma concolor) and jaguar (Panthera onca) prey consumption in northeastern Sonora, Mexico, by investigating global positioning system cluster sites (n = 220), and conducting molecular analyses of scat (n = 116) collected between 2011 and 2013. We used camera trap data (n = 8,976 camera days) to estimate relative abundances of pumas and jaguars. Deer (Odocoileus virginianus) was the most frequent prey for puma found at kill sites (67%) and identified from scat (74%), although based on relative numbers of prey consumed, deer represented 45% and lagomorphs 20% of the proportion of all individuals eaten. A variety of small prey (weighing kill sites. From prey found at kill sites, jaguars killed calves (Bos taurus) at a lower frequency than previously reported, whereas pumas preyed on calves at a higher frequency than previously reported in the same area. In our study area, jaguars preyed on calves at approximately the same rate as pumas (jaguars 3.7 calves per year, pumas 4.9 calves per year). Calculated predation rates were limited only to collared animals within our study area and therefore should not be considered applicable to all pumas and jaguars in Sonora.

    2013-01-01

    We studied Swainson's Hawks (Buteo swainsoni) in southeastern Arizona to assess the status of the local breeding population. Nest success (≥1 young fledged) was 44.4% in 1999 with an average of 1.43 ± 0.09 (SE) young produced per successful pair. Productivity was similar in 2000, with 58.2% nesting success and 1.83 ± 0.09 fledglings per successful pair. Mesquite (Prosopis velutina) and cottonwood (Populus fremontii) accounted for >50% of 167 nest trees. Nest trees were taller than surrounding trees and random trees, and overall there was more vegetative cover at nest sites than random sites. This apparent requirement for cover around nest sites could be important for management of the species in Arizona. However, any need for cover at nest sites must be balanced with the need for open areas for foraging. Density of nesting Swainson's Hawks was higher in agriculture than in grasslands and desert scrub. Breeding pairs had similar success in agricultural and nonagricultural areas, but the effect of rapid and widespread land-use change on breeding distribution and productivity continues to be a concern throughout the range of the species.

    The University of Arizona Astronomy Club is devoted to undergraduate success in astronomy, physics, planetary sciences and many other related fields. The club promotes many undergraduate opportunities; research projects, participating in telescope observational runs, sponsoring conference attendance as well as several public outreach opportunities. Research projects involving exoplanet transit observations and radio observations of cold molecular clouds allow undergraduates to experience data collection, telescope operations, data reduction and research presentation. The club hosts many star parties and various other public outreach events for the Tucson, Arizona location. The club often constructs their own outreach materials and structures. The club is currently working on creating a portable planetarium to teach about the night sky on the go even on the cloudiest of nights. The club is also working on creating a binocular telescope with two 10" mirrors as a recreation of the local Large Binocular Telescope for outreach purposes as well. This is a club that strives for undergraduate activity and involvement in a range of academic and extracurricular activates, and is welcoming to all majors of all levels in hopes to spark astronomical interest.

    Wings from mallard ducks harvested in 1980 in Arizona, Arkansas, Louisiana, and New Mexico were pooled into county aggregates and analyzed for organochlorine pesticides and PCB's. Organochlorine concentrations in duck wings were compared among counties comprising major river drainages within each state. DDE concentrations in the wings of mallards collected from the Verde River and the lower portion of the Gila River drainages in Arizona ranged up to 6 ppm (wet weight basis), which was 17 times higher than the 1979 Pacific Flyway average. DDE at these high levels may be hazardous to wildlife. In combination with other published data, our findings indicate a serious DDT problem in portions of the Verde River and Gila River drainages. High levels of heptachlor (up to 1.7 ppm) and PCB's (3.7 ppm, 61 times the 1979 Central Flyway average) were found in mallard wings from the upper Rio Grande and Pecos River drainages, respectively. We did not detect areas of heavy local organochlorine pesticide or PCB contamination in Arkansas and Louisiana.

    The study of the geochemical compositions and K-Ar or Ar-Ar ages of ca. 350 Neogene and Quaternary lavas from Baja California, the Gulf of California and Sonora allows us to discuss the nature of their mantle or crustal sources, the conditions of their melting and the tectonic regime prevailing during their genesis and emplacement. Nine petrographic/geochemical groups are distinguished: "regular" calc-alkaline lavas; adakites; magnesian andesites and related basalts and basaltic andesites; niobium-enriched basalts; alkali basalts and trachybasalts; oceanic (MORB-type) basalts; tholeiitic/transitional basalts and basaltic andesites; peralkaline rhyolites (comendites); and icelandites. We show that the spatial and temporal distribution of these lava types provides constraints on their sources and the geodynamic setting controlling their partial melting. Three successive stages are distinguished. Between 23 and 13 Ma, calc-alkaline lavas linked to the subduction of the Pacific-Farallon plate formed the Comondú and central coast of the Sonora volcanic arc. In the extensional domain of western Sonora, lithospheric mantle-derived tholeiitic to transitional basalts and basaltic andesites were emplaced within the southern extension of the Basin and Range province. The end of the Farallon subduction was marked by the emplacement of much more complex Middle to Late Miocene volcanic associations, between 13 and 7 Ma. Calc-alkaline activity became sporadic and was replaced by unusual post-subduction magma types including adakites, niobium-enriched basalts, magnesian andesites, comendites and icelandites. The spatial and temporal distribution of these lavas is consistent with the development of a slab tear, evolving into a 200-km-wide slab window sub-parallel to the trench, and extending from the Pacific coast of Baja California to coastal Sonora. Tholeiitic, transitional and alkali basalts of subslab origin ascended through this window, and adakites derived from the partial

    Speed cameras can reduce speeding and injury crashes, but in many communities they are confined to low-speed settings such as residential streets and school zones. In 2006 the city of Scottsdale, Arizona, implemented a 9-month pilot program to evaluate the feasibility and effects of highly visible speed camera enforcement on a busy urban freeway. This was the first use of fixed speed cameras on a major US highway. Deployment of six cameras along an 8-mile corridor was associated with large declines in mean speeds and an 88% decrease in the odds of vehicles traveling 11 mph or more above the 65 mph limit. Traffic speeds increased soon after the pilot program was suspended. In addition to reducing speeding along the enforcement corridor, speed cameras were associated with large reductions in speeding on the same highway but 25 miles away from the camera installations. However, traffic speeds were fairly stable on urban freeways in Scottsdale that were not part of the study road. Public opinion surveys found widespread concerns about speeding on the Loop 101 freeway and high levels of support for speed camera enforcement on this road.

    2012-12-01

    Results of recent fieldwork in Rayón, Sonora, Mexico (funded by NSF's "Strengthening Resilience of Arid Region Riparian Corridors") indicate that the coupled natural and human (CNH) system that has persisted since the town's founding in 1626 is being degraded and destabilised by a confluence of social and ecological pressures. System change or loss of key system services and products has important implications for ecological services and human economic activity in the riparian corridor. Less water quantity is the primary factor responsible for driving system degradation and change. Drought caused by climate change is widely perceived by agriculturists as responsible for reduced water quantity in the riparian area. Reductions in water quantity are so severe that the once perennial Rio San Miguel did not run during 2012's summer months for the first time in residents' memory. Ninety-percent of wells are dry. Fields irrigated by surface-water acequias were not planted. Starvation or dehydration has thinned herd sizes. Residents fear they will lose the ability to practice their traditional livelihoods: ranching, farming and cheese production. Drought conditions and resource management in response to climatic change have had a net negative impact on ecological services. Agriculturists have responded to less forage and pasture for cattle by clearing mesquite forests, putting land into production, and increasing water demand. From interviews it appears this process is cyclical: agriculturists widely believe access to more water or an end to the drought are the only ways to improve conditions. Interviews also reveal (a) agriculturists view technology, especially that which is able to improve water-use efficiency, as means to reduce stress in the CNH system and (b) a holistic view that couples natural well-being to human well-being is absent from the majority of respondents' worldviews. Technological and adoption of holistic perceptions are adaptations that may potentially

    2013-01-01

    The U.S. Geological Survey, in collaboration with the National Park Service Submerged Resources Center, undertook investigations at the USS Arizona Memorial at Pearl Harbor, Hawaii, in 2002, 2003, and 2005 to characterize geological factors affecting the deterioration and movement of the hull of the USS Arizona. Since sinking on the morning of December 7, 1941, the hull of the USS Arizona has been slowly but steadily disappearing below the surface of Pearl Harbor. Continuous sediment coring at three of four locations around the hull of the Arizona was only partially successful, but it was sufficient to identify a varied sedimentary substrate beneath the hull. A boring near the stern reveals a thick, continuous sequence of soft, gray clay to the bottom of the boring. In contrast, borings near the bow and starboard side, below about 5 meters subbottom depth, indicate the presence of very stiff, brown clay and coral debris and an absence of soft clay. Multisensor core logger scanning of the recovered cores distinguishes the lower density of the soft, gray clay at the stern from the higher density of the stiff, brown clays and coral debris at the bow and starboard side. Uniaxial consolidation testing of the soft gray clay indicates a normally consolidated sequence, whereas the stiff, brown clay and coral debris are overconsolidated. Profiles of shear wave velocity vs. depth obtained through spectral analysis of interface wave testing around the perimeter of the hull in 2005 identified areas of higher velocity, stiffer sediment at the bow and starboard side, which correspond to the dense, stiff clay recovered near the bow and starboard borings. Low shear-wave velocities at the port midship and quarter of the hull correlate with the lower density, softer sediment recovered from the boring at the stern. Cross sections of the subbottom of the Memorial combine results from the sediment borings and geophysical surveys and depict a wedge of soft clay unconformably overlying

    2002-01-01

    A spatial database was created for Drewes' (1980) tectonic map of southeast Arizona: this database supercedes Drewes and others (2001, ver. 1.0). Staff and a contractor at the U.S. Geological Survey in Tucson, Arizona completed an interim digital geologic map database for the east part of the map in 2001, made revisions to the previously released digital data for the west part of the map (Drewes and others, 2001, ver. 1.0), merged data files for the east and west parts, and added additional data not previously captured. Digital base map data files (such as topography, roads, towns, rivers and lakes) are not included: they may be obtained from a variety of commercial and government sources. This digital geospatial database is one of many being created by the U.S. Geological Survey as an ongoing effort to provide geologic information in a geographic information system (GIS) for use in spatial analysis. The resulting digital geologic map database can be queried in many ways to produce a variety of geologic maps and derivative products. Because Drewes' (1980) map sheets include additional text and graphics that were not included in this report, scanned images of his maps (i1109_e.jpg, i1109_w.jpg) are included as a courtesy to the reader. This database should not be used or displayed at any scale larger than 1:125,000 (for example, 1:100,000 or 1:24,000). The digital geologic map plot files (i1109_e.pdf and i1109_w.pdf) that are provided herein are representations of the database (see Appendix A). The map area is located in southeastern Arizona (fig. 1). This report describes the map units (from Drewes, 1980), the methods used to convert the geologic map data into a digital format, the ArcInfo GIS file structures and relationships, and explains how to download the digital files from the U.S. Geological Survey public access World Wide Web site on the Internet.

    The 1982 salary survey of the Medical Library Group of Southern California and Arizona (MLGSCA) indicates that 211 health sciences librarians in Southern California and Arizona earned a mean annual salary of $20,910 for 1982. Data analysis shows a positive correlation between salary and educational level. Other factors found to affect salary were job history, number of positions held, MLA certification, and professional responsibility. Age, gender, and MLA certification did not have a consistent positive correlation with salary. Results indicate that the salaries of hospital librarians are, on the average, roughly comparable to those of academic librarians in Southern California and Arizona. PMID:6743878

    2012-12-01

    Central to the "Smart Growth" movement is that compact development reduces vehicle miles traveled, carbon emissions, and water use. Empirical efforts to evaluate compact development have examined residential densities, but have not distinguished decreasing lot sizes from multifamily apartments as mechanisms for compact development. Efforts to link design features to water use have emphasized single-family at the expense of multifamily housing. This study isolates the determinants of water use in large (>50) unit apartment complexes in the city of Tempe, Arizona. In July 2007, per-bedroom water use increased with pool area, dishwashers, in-unit laundry facilities, and irrigated landscaping. We explain nearly 50% of the variation in water use with these variables. These results inform public policy for reducing water use in multifamily housing structures, suggesting strategies to construct and market "green" apartment units.

The thin white line extending from left corner to Sunset Crater fields is the power transmission line cleared area. Roads are subdued and are not easily visible.

  5. Arizona Education Tax Credit and Hidden Considerations of Justice

    Directory of Open Access Journals (Sweden)

    Michele S. Moses

    2000-08-01

    Full Text Available The current debate over market-based ideas for educational reform is examined, focusing specifically on the recent movement toward education tax credits. Viewing the Arizona education tax credit law as a voucher plan in sheep's clothing, I argue that the concept of justice underlying the law is a crucial issue largely missing from the school choice debate. I question the libertarian conception of justice assumed by voucher and tax credit advocates, and argue instead that a contemporary liberal democratic conception of justice ought to undergird attempts at school reform. A call for educators and policymakers to concentrate energies on efforts to help needy students rather than on efforts to channel tax dollars toward self- interested ends concludes the article.

    In the middle San Pedro Watershed in southeastern Arizona, groundwater is the primary source of water supply for municipal, domestic, industrial, and agricultural use. The watershed comprises two smaller subareas, the Benson subarea and the Narrows-Redington subarea. Early 21st century projections for heavy population growth in the watershed have not yet become a reality, but increased groundwater withdrawals could have undesired consequences—such as decreased base flow to the San Pedro River, and groundwater-level declines—that would lead to the need to deepen existing wells. This report describes the hydrology, hydrochemistry, water quality, and development of a groundwater budget for the middle San Pedro Watershed, focusing primarily on the elements of groundwater movement that could be most useful for the development of a groundwater model

    Naegleria fowleri is a free-living amoeba found in waters in warmer regions that causes primary amoebic meningoencephalitis, a rare but almost universally fatal disease. The goal of this project was to assess the occurrence of N. fowleri and other thermophilic amoebae in 33 recreational surface waters across Arizona to determine if their presence could be correlated with seasonal or other environmental factors. First, 1-L grab samples were collected over two years and analyzed using polymerase chain reaction and amoebae viability. Seasonality was observed, with N. fowleri and thermophilic amoebae (20% and 30%, respectively) being detected more often in the winter and spring combined than in the summer and fall combined (7.9% and 9.5%, respectively). The spring and fall both had an average temperature of 18°C, yet had different occurrence data (18.2% versus 5.9% for N. fowleri, respectively; 27.3% versus 0% for viable amoebae, respectively). These results are in stark contrast to previous studies in which N. fowleri has been found almost exclusively during warmer months. Over the two-year study, N. fowleri was detected in six and thermophilic amoebae in eight of the 33 recreational water bodies. Five of these were lakes near Phoenix that tested positive for N. fowleri and thermophilic amoebae over multiple seasons. These lakes differed significantly (P ≤ 0.05) from the other 28 surface waters, with a lower average temperature in the spring, a higher temperature in the fall, a higher pH and turbidity in the summer, and a lower electro-conductivity in the spring. They also had lower Escherichia coli and heterotrophic bacteria levels during colder months. Future N. fowleri monitoring in Arizona should focus on these five lakes to further elucidate the factors that contribute to the low occurrence of this amoeba in the summer or which might explain why these lakes appear to be reservoirs for the organism.

    Full Text Available A nivel internacional se ha demostrado que la contaminación acústica es uno de los principales impactos ambientales que afecta a la población y al medio urbano, y su diversidad en fuentes e intensidades sonoras dificulta mucho su control. El control y la evaluación del impacto ambiental en la infraestructura vial es relativamente reciente en los países en vía de desarrollo y la tendencia mundial apunta en la incorporación de los estudios de impacto ambiental dentro de los planes de ordenamiento territorial y la disponibilidad de herramientas ambientales que permitan desarrollar los planes, programas y proyectos preventivos correctivos o de seguimiento con el fin de identificar las fuentes generadoras potenciales que futuros proyectos urbanos generarían en el medio ambiente. Debido a la importancia en el ámbito urbano, el Ministerio De Ambiente, Vivienda y Desarrollo Territorial, MAVDT, emitió la resolución 0627 del 7 de abril de 2006, con el fin de establecer niveles máximos de ruido y la elaboración de los mapas de ruidos por parte de las autoridades ambientales. Un modelo de predicción de ruido del parque vehicular es una herramienta que permite determinar los niveles de intensidades sonoras y simular varias situaciones adversas y favorables que se producirán en una vía de circulación de tráfico rodado o bien una modificación a una vía existente. En este estudio se realizará una comparación de los resultados arrojados por un modelo teórico y uno computacional, la cual nos permitirá validar el modelo teórico y reconocer la desviación porcentual entre sus intensidades sonoras calculadas. Con los resultados obtenidos se realizará una correlación con la normatividad vigente colombiana y otra norma alemana RLS90 con el fin de conocer la desviación existente con los niveles permisibles legales. La modelación computacional también nos permitirá predecir el ruido generado por el crecimiento del flujo vehicular y

    Full Text Available Building on Arizona State University's patron-driven acquisitions (PDA initiative in 2009, the Arizona Universities Library Consortium, in partnership with the Ingram Content Group, created a cooperative patron-driven model to acquire electronic books (e-books. The model provides the opportunity for faculty and students at the universities governed by the Arizona Board of Regents (ABOR to access a core of e-books made accessible through resource discovery services and online catalogs. These books are available for significantly less than a single ABOR university would expend for the same materials. The patron-driven model described is one of many evolving models in digital scholarship, and, although the Arizona Universities Library Consortium reports a successful experience, patron-driven models pose questions to stakeholders in the academic publishing industry.
