    From Argentin lake, at west on Andean hills, to Puerto Santa Cruz on Atlantic coast, Santa Cruz river cross eastward Santa Cruz province over 250 km in Patagonia at southern Argentina. Present bed of the river has a meandering outline with first order meanders of great ratio bends and second order meanders of minor ratio bends. Principal wanderings are 45 to 55 km spaced from near Estancia La Julia or Rio Bote at west to Comandante Luis Piedrabuena at east. On river's bed middle sector these great curvatures are located at Estancia Condor Cliff and Estancia Rincon Grande. Regional and partial detailed studies allow to recognize structural control on river's bed sketch and valley s geomorphology that relates first order bends with reactivated principal faults. These faults fit well with parallel system of northwest strike of Austral Basin.On geological, geomorphologic and structural evidences recognized in Santa Cruz river, quaternary tectonic activity, related to Andean movements in southern Patagonian foreland, is postulated.

    Full Text Available Se describe la alimentación de una población de Bufo variegatus procedente de la región de Lago del Desierto, provincia de Santa Cruz, Argentina. De los 11 ítems presa identificados, los más consumidos por los adultos (tanto machos como hembras fueron los coleópteros. En los machos la segunda categoría presa mas importante en la contribución a la dieta fueron los ácaros, mientras que en las hembras las hormigas y las larvas de insectos siguieron en importancia al consumo de coleópteros. En los especímenes juveniles, los ácaros fueron las presas más consumidas, quedando los coleópteros en segundo lugar en importancia relativa. Se demuestra la existencia de una correlación positiva significativa entre el volumen de las presas y el tamaño del depredador. Se aportan datos referentes a la fecundidad de B. variegatus y se comprueba la ausencia de correlación entre el tamaño de las hembras grávidas y el número de óvulos maduros. The diet of a population of Bufo variegatus from the region of Lago del Desierto, Santa Cruz province, Argentina, is described. Of the 11 prey items identified, Coleoptera was the most consumed prey both for males and females. In males, the second most important prey was Acarii, while in females they were the ants and insect larvae. Acarii was the most consumed prey for juveniles, followed by Coleoptera. A significant positive correlation was found between prey volume and predator body size. Fecundity information for B. variegwus is given, and a lack of correlation between snout-vent length of mature females and ovarian egg complement is demonstrated.

    Around 11.5 ∗ 106 m3 of rock detached from the eastern slope of the Santa Cruz valley (San Juan province, Argentina) in the first fortnight of January 2005. The rockslide-debris avalanche blocked the course, resulting in the development of a lake with maximum length of around 3.5 km. The increase in the inflow rate from 47,000-74,000 m3/d between April and October to 304,000 m3/d between late October and the first fortnight of November, accelerated the growing rate of the lake. On 12 November 2005 the dam failed, releasing 24.6 ∗ 106 m3 of water. The resulting outburst flood caused damages mainly on infrastructure, and affected the facilities of a hydropower dam which was under construction 250 km downstream from the source area. In this work we describe causes and consequences of the natural dam formation and failure, and we dynamically model the 2005 rockslide-debris avalanche with DAN3D. Additionally, as a volume ~ 24 ∗ 106 m3of rocks still remain unstable in the slope, we use the results of the back analysis to forecast the formation of a future natural dam. We analyzed two potential scenarios: a partial slope failure of 6.5 ∗ 106 m3 and a worst case where all the unstable volume remaining in the slope fails. The spreading of those potential events shows that a new blockage of the Santa Cruz River is likely to occur. According to their modeled morphometry and the contributing watershed upstream the blockage area, as the one of 2005, the dams would also be unstable. This study shows the importance of back and forward analysis that can be carried out to obtain critical information for land use planning, hazards mitigation, and emergency management.

    In the Central Andes of Argentina, ephemeral river blockage due to landslides deposition are common phenomena. During the first fortnight of January 2005, 11.5 * 106m3 of rock collapsed from the east slope of the Santa Cruz valley (San Juan province, Argentina). The rock mass displaced from 4300 m a.s.l., down to the valley bottom, at 2900 m a.s.l., and ran up the opposite flank of the valley. This produced the blockage of the Santa Cruz river and generated the Los Erizos lake. The rapid snow melting during the spring season caused the increase of the water level of the reservoir, leading to a process of overtopping on November 12th of 2005. 30 * 106m3 of water were released from the reservoir and the consequent outburst flood displaced along 250 km. From local reports of arrival times, we estimated that the outburst flood reduced its velocity from around 40 km/h near the source area to 6 km/h in its distal section. A road, bridges, and a mining post where destroyed. 75 tourists had to be rescued from the mountains using helicopters, and people from two localities had to be evacuated. Near its distal part, the flood damaged the facilities of the Caracoles power dam, which was under construction, and its inauguration had to be delayed one year due to the damage. The outburst flood produced changes in the morphology of the valley floor along almost all its path (erosion of alluvial fans, talus and terraces, and deposition of boulders). The most significant changes occurred in the first 70 km, especially upstream narrow sections, showing the importance of the backwater effects due to hydraulic ponding. In this work we carried out numerical simulations to obtain the velocity patterns of the flood, and compared them with those obtained from local reports. Furthermore, we analyze the relationship between the dynamics of the flood with the patterns of erosion and deposition near the source area.

    The aim of the present study was to examine the parasite remains present in rodent coprolites collected from the archaeological site Cerro Casa de Piedra 7 (CCP7), located in the Perito Moreno National Park (47°57'S, 72°05'W), Santa Cruz Province, Argentina. Eight coprolites obtained from the layer 17, dated at 10,620 ± 40 to 9,390 ± 40 yr B.P., were examined for parasites. Feces were processed whole, rehydrated, homogenized, subjected to spontaneous sedimentation, and examined via light microscopy. Eggs of parasites were measured and photographed. Seven of 8 coprolites possessed 199 eggs of 2, probably new, species of nematodes, including 43 eggs of Heteroxynema sp. Hall, 1916 (Cavioxyura sp. Quentin, 1975) (Oxyurida, Heteroxynematidae), and 156 eggs of Trichuris sp. Roederer, 1761 (Trichinellida, Trichuridae). Heteroxynema sp. is cited for the first time from ancient material worldwide. The finding of Trichuris spp. in both rodents and other host samples from the area under study is indicative of the stability of the biological and environmental conditions for this nematode genus to establish in the Patagonian Early Holocene. The rodent host was assigned to an unknown species of Caviomorpha (Hystricognathi) that lived during the Pleistocenic transition in Patagonia.

    Full Text Available Commerson's dolphins, Cephalorhynchus commersonii, suffer bycatch in fisheries and are target of dolphin-watching activities along Patagonia. Here we described dolphins' habitat use and behavioural pattern at the estuary of Santa Cruz River. Behavioural observations were made from vantage points using a spotting scope. Boat surveys were conducted randomly from Puerto Santa Cruz to the mouth of the river to analyze the habitat use. The survey area was divided into 1 km² cells and characterized with depth and benthic slope. The described behaviours for the Commerson's dolphin were: travelling, slow travelling, milling, resting, socializing, stationary swimming and diving. A new behavioural context was assigned to diving, a behaviour that showed a high frequency during downing tide, suggesting a benthic foraging strategy. Additionally, we found a strong influence of the tide on Commerson's dolphin behaviour. Habitat use models indicated that dolphins prefer shallow water inside the estuary. The knowledge of the behavioural patterns and the habitat use of these endemic species, in this unexplored area, provide tools for management and conservation purposes.

  12. Streamflow in the upper Santa Cruz River basin, Santa Cruz and Pima Counties, Arizona

    1970-01-01

    Streamflow records obtained in the upper Santa Cruz River basin of southern Arizona, United States, and northern Sonora, Mexico, have been analyzed to aid in the appraisal of the surface-water resources of the area. Records are available for 15 sites, and the length of record ranges from 60 years for the gaging station on the Santa .Cruz River at Tucson to 6 years for Pantano Wash near Vail. The analysis provides information on flow duration, low-flow frequency magnitude, flood-volume frequency and magnitude, and storage requirements to maintain selected draft rates. Flood-peak information collected from the gaging stations has been projected on a regional basis from which estimates of flood magnitude and frequency may be made for any site in the basin. Most streams in the 3,503-square-mile basin are ephemeral. Ground water sustains low flows only at Santa Cruz River near Nogales, Sonoita Creek near Patagonia, and Pantano Wash near Vail. Elsewhere, flow occurs only in direct response to precipitation. The median number of days per year in which there is no flow ranges from 4 at Sonoita Creek near Patagonia to 335 at Rillito Creek near Tomson. The streamflow is extremely variable from year to year, and annual flows have a coefficient of variation close to or exceeding unity at most stations. Although the amount of flow in the basin is small most of the time, the area is subject to floods. Most floods result from high-intensity precipitation caused by thunderstorms during the period ,July to September. Occasionally, when snowfall at the lower altitudes is followed by rain, winter floods produce large volumes of flow.

Al mismo tiempo, la conservación de las colecciones bioarqueológicas, destacándose la pérdida de restos óseos e información asociada por escasez de recursos, desconocimiento o falta de atención especializada, representa escenarios de riesgo para el registro. Una de las áreas para las cuales no se dispone hasta el momento de información bioarqueológica es la región que comprende la costa meridional de la provincia de Santa Cruz. Considerando esta ausencia de información, el objetivo de este trabajo es presentar y discutir los primeros resultados sobre restos óseos humanos hallados en la región costera próxima a la desembocadura del Río Santa Cruz (Santa Cruz, Argentina. Los estudios incluyen el análisis de las situaciones de hallazgo y riesgo de los restos recuperados en acciones de rescate, el reconocimiento y puesta en valor de materiales depositados en el Museo Regional "Carlos Borgialli" (Puerto Santa Cruz, Santa Cruz, Argentina y estudios paleopatológicos. Al mismo tiempo se informan y analizan resultados cronológicos e isotópicos. Los resultados brindan evidencias claras de la ocupación de la región costera al menos durante los últimos 2000 años, consumo de recursos predominantemente terrestres y un estilo de vida que favorece el desarrollo de lesiones articulares, con escasos indicios de estrés sistémico que coinciden con los resultados reportados para la región continental del estrecho de Magallanes.

La finalidad que se persiguió fue estudiar el grado de escarificabilidad del subsuelo bajo la traza mencionada, a lo largo de una extensión de 5000 m, comprendidos en dos secciones cercanas entre sí. Esta determinación permite calcular costos de voladuras o escarificables. La zona de estudio se caracteriza por presentar un paisaje típico de estepa patagónica, con presencia de coladas basálticas indicando vulcanismo antiguo. En la superficie se observó suelos aluvionales finos a medios con presencia en ocasiones de orgánicos y además en algunos sitios grandes bloques de basalto. Se realizaron 50 tendidos sísmicos, los cuáles fueron distribuidos a lo largo de la traza en forma continua. En cada uno de los tendidos se efectuaron lecturas de ida, vuelta, desde el punto central hacia los extremos y 2 tiros lejanos; la configuración de geófonos y disparos se determinó en campo en pruebas previas y de acuerdo a la disponibilidad de espacio. En general la longitud de los perfiles estuvo situada entre 25 y 100m y la separación entre geófonos fue de 5m, con objeto de garantizar el detalle de la investigación.

    This investigation aimed to document surgical capacity at public medical centers in a middle-income Latin American country using the Surgeons OverSeas (SOS) Personnel, Infrastructure, Procedures, Equipment, and Supplies (PIPES) survey tool. We applied the PIPES tool at six urban and 25 rural facilities in Santa Cruz, Bolivia. Outcome measures included the availability of items in five domains (Personnel, Infrastructure, Procedures, Equipment, and Supplies) and the PIPES index. PIPES indices were calculated by summing scores from each domain, dividing by the total number of survey items, and multiplying by 10. Thirty-one of the 32 public facilities that provide surgical care in Santa Cruz were assessed. Santa Cruz had at least 7.8 surgeons and 2.8 anesthesiologists per 100,000 population. However, these providers were unequally distributed, such that nine rural sites had no anesthesiologist. Few rural facilities had blood banking (4/25), anesthesia machines (11/25), postoperative care (11/25), or intensive care units (1/25). PIPES indices ranged from 5.7-13.2, and were significantly higher in urban (median 12.6) than rural (median 7.8) areas (P Bolivia's development status. Unfortunately, surgeons are limited in rural areas by deficits in anesthesia and perioperative services. These results are currently being used to target local quality improvement initiatives.

    Full Text Available Los circuitos turísticos no convencionales como Patagonia reciben cada vez mayor interés mundial debido a que no sólo promueven el atractivo natural de la región, sino también la visita a lugares en los que se encuentran bienes arqueológicos. Cualquier actividad que no considere medidas que mitiguen las acciones que se ejerzan sobre el registro arqueológico le producirá un daño irreversible. Si bien la problemática referida al turismo y patrimonio arqueológico usado como recurso turístico ha sido debatida muy ampliamente por décadas a nivel nacional y en la provincia de Santa Cruz, aún no se logra una tarea conjunta entre las instituciones involucradas en la preservación de los bienes arqueológicos. En este trabajo se hace referencia a un estado de la cuestión en la provincia de Santa Cruz y se delinea una metodología que contempla los criterios de una adecuada preservación del registro arqueológico para una correcta regulación de la oferta al público. Entre otros elementos de enfoque, se encuadra la situación en una necesaria perspectiva a escala de ordenamiento y planificación territorial, como marco más general para insertar la problemática, en pos de un equilibrio entre conservación y desarrollo.

    This guide contains a road log and five stop descriptions for a field trip in the southern Santa Cruz Mountains. The trip officially begins at the boat dock parking area on Alma Bridge Road near the dam of Lexington Reservoir. Stop 1 involves a walk up the Limekiln Trail to examine a large landslide in serpentinite that frequently takes out the trail. Stop 2 is at Miller Point picnic area along the shore of the reservoir where exposures of massive, fractured graywacke sandstone are capped with terrace gravel deposits. Stop 3 is along Highland Way in the Santa Cruz Mountains where large landslides have occasionally force the closure of the road. Stop 4A-C are several closely spaced outcrop areas along Loma Prieta Avenue and Summit-Mt. Madonna Road in the Loma Prieta summit area. A walk to scenic vista points provide opportunity to discuss the evolution of regional landscape along the crest of the Sierra Azul. In addition, a variety of rock types are exposed in the Stop 4 area along a series of road cuts, including Cretaceous age conglomerate, turbidites (consisting of interbedded sandstone and shale), and fossiliferous mudstone. Stop 5 involves returning to the boat dock parking area to examine geology and the placement of the Lexington Dam in the Los Gatos Creek canyon.

    Background We conducted a study of congenital Trypanosoma cruzi infection in Santa Cruz, Bolivia. Our objective was to apply new tools to identify weak points in current screening algorithms, and find ways to improve them. Methods Women presenting for delivery were screened by rapid and conventional serological tests. For infants of infected mothers, blood specimens obtained on days 0, 7, 21, 30, 90, 180, and 270 were concentrated and examined microscopically; serological tests were performed for the day 90, 180, and 270 specimens. Maternal and infant specimens, including umbilical tissue, were tested by polymerase chain reaction (PCR) targeting the kinetoplast minicircle and by quantitative PCR. Results Of 530 women, 154 (29%) were seropositive. Ten infants had congenital T. cruzi infection. Only 4 infants had positive results of microscopy evaluation in the first month, and none had positive cord blood microscopy results. PCR results were positive for 6 (67%) of 9 cord blood and 7 (87.5%) of 8 umbilical tissue specimens. PCR-positive women were more likely to transmit T. cruzi than were seropositive women with negative PCR results (P < .05). Parasite loads determined by quantitative PCR were higher for mothers of infected infants than for seropositive mothers of uninfected infants (P < .01). Despite intensive efforts, only 58% of at-risk infants had a month 9 specimen collected. Conclusions On the basis of the low sensitivity of microscopy in cord blood and high rate of loss to follow-up, we estimate that current screening programs miss one-half of all infected infants. Molecular techniques may improve early detection. PMID:19877966

Moreno. Hacia fines de ese año, Florentino Ameghino, Secretario Subdirector del Museo de La Plata, dio a conocer dichos hallazgos describiendo sucintamente 122 taxones de los cuales 110 eran nuevas especies. Al poco tiempo, Florentino era exonerado del Museo, negándosele el acceso a las colecciones. No obstante, en 1889 Ameghino amplió sus descripciones y figuró 74 de los taxones de 1887. En 1891 Florentino Ameghino explicó que sus descripciones y figuras de 1889 se basaron en apuntes y croquis realizados antes de ser exonerado. Llamativamente, muchos de los ejemplares figurados se encuentran depositados en la Colección Naci onal Ameghino, alojada en el Museo Argentino de Ciencias Naturales "Bernardino Rivadavia". En 1980, basándose en este impensado destino de los fósiles, Larry Marshall concluyó que Florentino Ameghino se habría apropiado de una parte de la colección de 1887 y sobre ésta basó su obra de 1889. Las evidencias aquí presentadas avalan la apropiación de ejemplares propuesta por Marshall y brinda un marco de referencia para evaluar la conformación de las series tipo de las especies de 1887.

    Full Text Available The fresh market berry industry in Santa Cruz and Monterey counties has contributed significantly to the agricultural vibrancy of the two counties and the state of California. Dramatic growth in strawberry, raspberry and blackberry production has been documented over the last 50 years, and most notably since the 1980s. Factors influencing this growth include innovations in agricultural practices and heightened consumer demand. Here, we review the historical context for the berry industry in Santa Cruz and Monterey counties. Organic production, production economics and challenges for the future are also discussed.

    Full Text Available In this article, we reconstruct one of the main representation strategies and sources of power for Néstor Kichner’s leadership in Santa Cruz, Argentina between 1991 and 1996: his consolidation as a “warrantor of order and stability”. In second stance, we will analyze the social conditions that explain the success of this strategy of representation. Mainly, its affinity with a set of social attributes of the province defined as part of the “culture of suffering” and the ability of the Frente para la Victoria as an organization to embody analog values. We use for the making of this article mostly semi-structured interviews and analysis of journalistic archives. This work is a valuable study on the forms of power construction of the Frente para la Victoria since its origins, in the early 1990, a previous experience to its access of the national government in 2003.

As pesquisas realizadas nas escolas municipais, estaduais e privadas na região de Santa Cruz do Sul permitem uma análise pontual das relações entre a educação e a imobilidade social, cujo resultado pode ser avaliado na dinâmica da visibilidade/invisibilidade identitária e processos de exclusão comunitário destes grupos, nomeadamente dos afrodescendentes.The objective of this article is to analyze the relations among education, ethnicity and social mobility in the region of German colonization in Rio Grande do Sul, and mainly in Santa Cruz do Sul, Brazil, a city with strong German identity speech. Taking into consideration that it is a city characterized by Germanism, what was observed in the researches accomplished until now, including the last six years, is that the region in question has a significant population of non-white people, though socially invisible and excluded from the identitary inclusion process of the region community. The researches that were carried out in the private and public – municipal and state – schools in the region of Santa Cruz do Sul permit sharp analysis of the relations between education and social immobility, which result can be evaluated in the identitary visibility/invisibility dynamic and processes of community exclusion of those groups, nominally of Afro-descendants.

    The distribution, chemistry, and morphology of Fe nodules were studied in a marine terrace soil chronosequence northwest of Santa Cruz, California. The Fe nodules are found at depths hyphae throughout the nodules, including organic structures incorporating fine-grained Fe oxides. The fine-grained nature of the Fe oxides was substantiated by M??ssbauer spectroscopy. Our microscopic observations led to the hypothesis that the nodules in the Santa Cruz terrace soils are precipitated by fungi, perhaps as a strategy to sequester primary mineral grains for nutrient extraction. The fungal structures are fixed by the seasonal wetting and dry cycles and rounded through bioturbation. The organic structures are compacted by the degradation of fungal C with time. ??

    The USA and Mexico have initiated comprehensive assessment of 4 of the 18 aquifers underlying their 3000 km border. Binational management of groundwater is not currently proposed. University and agency researchers plus USA and Mexican federal, state, and local agency staff have collaboratively identified key challenges facing the Santa Cruz River Valley Aquifer located between the states of Arizona and Sonora. The aquifer is subject to recharge variability, which is compounded by climate change, and is experiencing growing urban demand for groundwater. In this paper, we briefly review past, current, and projected pressures on Santa Cruz groundwater. We undertake first-order approximation of the relative magnitude of climate change and human demand drivers on the Santa Cruz water balance. Global circulation model output for emissions scenarios A1B, B1, and A2 present mixed trends, with annual precipitation projected to vary by ±20% over the 21st century. Results of our analysis indicate that urban water use will experience greater percentage change than climate-induced recharge (which remains the largest single component of the water balance). In the Mexican portion of the Santa Cruz, up to half of future total water demand will need to be met from non-aquifer sources. In the absence of water importation and with agricultural water use and rights increasingly appropriated for urban demand, wastewater is increasingly seen as a resource to meet urban demand. We consider decision making on both sides of the border and conclude by identifying short- and longer-term opportunities for further binational collaboration on transboundary aquifer assessment.

    We report the results of an investigation of a small outbreak of hantavirus pulmonary syndrome in 2002 in the Department of Santa Cruz, Bolivia, where the disease had not previously been reported. Two cases were initially reported. The first case was a physician infected with Laguna Negra virus during a weekend visit to his ranch. Four other persons living on the ranch were IgM antibody-positive, two of whom were symptomatic for mild hantavirus pulmonary syndrome. The second case was a migrant sugarcane worker. Although no sample remained to determine the specific infecting hantavirus, a virus 90% homologous with Río Mamoré virus was previously found in small-eared pygmy rice rats (Oligoryzomys microtis) trapped in the area. An antibody prevalence study conducted in the region as part of the outbreak investigation showed 45 (9.1%) of 494 persons to be IgG positive, illustrating that hantavirus infection is common in Santa Cruz Department. Precipitation in the months preceding the outbreak was particularly heavy in comparison to other years, suggesting a possible climatic or ecological influence on rodent populations and risk of hantavirus transmission to humans. Hantavirus infection appears to be common in the Santa Cruz Department, but more comprehensive surveillance and field studies are needed to fully understand the epidemiology and risk to humans.

    The marine terraces in and around Santa Cruz, California, represent a set of well-preserved terraces formed as a product of geology, sea level, and climate. A marine terrace begins as a wave cut platform. Eustatic sea level changes, seacliff erosion, and tectonic uplift work together to generate marine terraces. "When a wave-cut platform is raised (due to tectonic activity) above sea level and cliffed by wave action it becomes a marine terrace" (Bradley, 1957, p. 424). During glacial periods, eustatic sea level is estimated to have dropped by 150 meters (Fairbanks, 1989). Cliff retreat measured from aerial photographs between 1930 and 1980 vary from 0.0 to 0.2 m yr–1 (Best and Griggs, 1991). Estimates of uplift rates along the Santa Cruz coastline vary from 0.10 to 0.48 m kyr–1 (Bradley and Griggs, 1976; Weber and others, 1999). Uplift mechanisms include coseismic uplift associated both with a reverse component of slip on the steeply SW dipping Loma Prieta fault in the restraining bend of the San Andreas Fault and a small component of reverse slip on the steeply SE dipping San Gregorio fault (Anderson and Menking 1994). Previous work studying physical properties on these terraces include Pinney and others (in press) and Aniku (1986) and Bowman and Estrada (1980). Sedimentary deposits of the marine terraces are a mixture of terrestrial and marine sediments but generally consist of a sheet of marine deposits overlying the old platform and a wedge of nonmarine deposits banked against the old sea cliff (Bradley, 1957). Bedrock underlying the terraces in the Santa Cruz area is generally either Santa Margarita Sandstone or Santa Cruz Mudstone. The Santa Margarita Sandstone represents an upper Miocene, transgressive, tidally dominated marine-shelf deposit with crossbedded sets of sand and gravel and horizontally stratified and bioturbated invertebrate-fossils beds (Phillips, 1990). The siliceous Santa Cruz Mudstone, of late Miocene age, conformably overlies the Santa

    The late Quaternary marine terraces near Santa Cruz, California, reflect uplift associated with the nearby restraining bend on the San Andreas fault. Excellent correspondence of the coseismic vertical displacement field caused by the 17 October 1989 magnitude 7.1 Loma Prieta earthquake and the present elevations of these terraces allows calculation of maximum long-term uplift rates 1 to 2 kilometers west of the San Andreas fault of 0.8 millimeters per year. Over several million years, this uplift, in concert with the right lateral translation of the resulting topography, and with continual attack by geomorphic processes, can account for the general topography of the northern Santa Cruz Mountains.

    IntroductionIn 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP), designed to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats, and geology within the limit of California’s State Waters. The CSMP approach is to create highly detailed seafloor maps through collection, integration, interpretation, and visualization of swath sonar data, acoustic backscatter, seafloor video, seafloor photography, high-resolution seismic-reflection profiles, and bottom-sediment sampling data. The map products display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow subsurface geology.The Offshore of Santa Cruz map area is located in central California, on the Pacific Coast about 98 km south of San Francisco. The city of Santa Cruz (population, about 63,000), the largest incorporated city in the map area and the county seat of Santa Cruz County, lies on uplifted marine terraces between the shoreline and the northwest-trending Santa Cruz Mountains, part of California’s Coast Ranges. All of California’s State Waters in the map area is part of the Monterey Bay National Marine Sanctuary.The map area is cut by an offshore section of the San Gregorio Fault Zone, and it lies about 20 kilometers southwest of the San Andreas Fault Zone. Regional folding and uplift along the coast has been attributed to a westward bend in the San Andreas Fault Zone and to right-lateral movement along the San Gregorio Fault Zone. Most of the coastal zone is characterized by low, rocky cliffs and sparse, small pocket beaches backed by low, terraced hills. Point Santa Cruz, which forms the north edge of Monterey Bay, provides protection for the beaches in the easternmost part of the map area by sheltering them from the predominantly northwesterly waves.The shelf in the map area is underlain by variable amounts (0 to 25 m) of

    1994-01-01

    The consumption of lacteal desserts in the province of Santa Cruz de Tenerife is notably high. However, there are no legal standards in Spain regarding microbiological quality. For this reason, we have decided that it would be of interest to carry out a health-sanitary study of these products, with the aim of discovering their microbial content. 330 samples of lacteal desserts on sale in the province of Santa Cruz de Tenerife have undergone analysis. They have been divided into three groups: cream caramel (egg and vanilla) (80), mousse (60) and the third group, known as "other desserts", which includes custard and the rest of lacteal desserts not included in the previous groupings (190). Neither E. coli, Salmonella spp., Shigella spp., nor Staphylococcus aureus have been detected in any of the samples analysed. In spite of the fact that the results obtained do not reflect high microbiological contamination, we consider it necessary to lay down legal standards, with reference values, for these lacteal products, which will guarantee good microbiological quality.

    On February 6, 2013 at 01:12:27 UTC (local time: UTC+11), a magnitude Mw 8.0 earthquake occurred 70 km to the west of Ndendo Island (Santa Cruz Island) in the Solomon Islands. The under-thrusting earthquake near a 90° bend, where the Australian plate subducts beneath the Pacific plate generated a locally focused tsunami in the Coral Sea and the South Pacific Ocean. The tsunami claimed the lives of 10 people and injured 15, destroyed 588 houses and partially damaged 478 houses, affecting 4,509 people in 1,066 households corresponding to an estimated 37% of the population of Santa Cruz Island. A multi-disciplinary international tsunami survey team (ITST) was deployed within days of the event to document flow depths, runup heights, inundation distances, sediment and coral boulder depositions, land level changes, damage patterns at various scales, performance of the man-made infrastructure and impact on the natural environment. The 19 to 23 February 2013 ITST covered 30 locations on 4 Islands: Ndendo (Santa Cruz), Tomotu Noi (Lord Howe), Nea Tomotu (Trevanion, Malo) and Tinakula. The reconnaissance completely circling Ndendo and Tinakula logged 240 km by small boat and additionally covered 20 km of Ndendo's hard hit western coastline by vehicle. The collected survey data includes more than 80 tsunami runup and flow depth measurements. The tsunami impact peaked at Manoputi on Ndendo's densely populated west coast with maximum tsunami height exceeding 11 m and local flow depths above ground exceeding 7 m. A fast tide-like positive amplitude of 1 m was recorded at Lata wharf inside Graciosa Bay on Ndendo Island and misleadingly reported in the media as representative tsunami height. The stark contrast between the field observations on exposed coastlines and the Lata tide gauge recording highlights the importance of rapid tsunami reconnaissance surveys. Inundation distance and damage more than 500 m inland were recorded at Lata airport on Ndendo Island. Landslides were

    Full Text Available On April 29, 2003, a catastrophic flood occurred in the Argentina city of Santa Fe de la Vera Cruz. Soon, the disaster became a political issue, as they had made serious accusations against the authorities and decision makers regarding negligence, corruption and lack of disaster preparedness. A local protest movement emerged, claiming both the allocation of responsibilities and financial compensation for the losses suffered by the victims. This article analyses the role of material memory and oblivion on the post disaster scene, more specifically, how different social actors in Santa Fe used places and objects in the contentious making of a disaster memoryscape. The analysis is based on ethnography from transtemporal translocal and field research conducted in Santa Fe between 2004 and 2011, and applies anthropological and sociological theories of memory to analyse these processes. Resumen El 29 de abril de 2003, ocurrió la peor inundación catastrófica en la historia de la ciudad argentina de Santa Fe de la Vera Cruz. Al poco tiempo, el desastre se convirtió en una cuestión política, ya que se habían realizado graves acusaciones contra las autoridades y tomadores de decisiones con respecto a la negligencia, la corrupción y la falta de preparación para desastres. Surgió un movimiento de protesta demandando tanto la asignación de responsabilidades, como la compensación económica por las pérdidas sufridas por las víctimas. Este artículo analiza el papel de la memoria material y el olvido en el escenario del posdesastre, y más específicamente cómo los diferentes actores sociales en Santa Fe usaron los lugares y los objetos en una contienda por construir un memo-paisaje del desastre. El análisis se basa en etnografía de trabajo de campo translocal y transtemporal realizado en Santa Fe entre 2004 y 2011, y aplica las teorías antropológicas y sociológicas de la memoria a fines de analizar estos procesos.

  18. The Border Environmental Health Initiative: Investigation of the Transboundary Santa Cruz Watershed

    In the borderland region of the desert southwest, human health and the ecosystems upon which humans rely largely depend on the quality, quantity, and distribution of water resources. In the Santa Cruz River Watershed (SCW), located in the Arizona and Sonora, Mexico border region, surface water is scarce and unreliable, and, during much of the year, is composed of effluent from the local wastewater treatment plant. This makes groundwater the preferred and, consequently, primary source for industrial, agricultural, and domestic use. USGS scientists are using an integrative approach, incorporating the expertise of the Geography, Water, Biology, and Geology disciplines to identify risks to water resources in the SCW, and the potential for impacts to riparian ecosystems and ultimately, human health. This includes tracking organic and inorganic contaminants and their effects from sources to sinks in sediment, water, plants, and animals. Existing ground- and surface-water models will be used and modified to assess contaminant and sediment transport. Water quality, sediment, aquatic macro invertebrates, aquatic plants (macrophytes), algae, riparian grasses, fish, and birds will be sampled at five locations along the Santa Cruz River. Field sampling data will be obtained at sites that coincide with historical sampling programs. Site locations include (i.) the Santa Cruz River headwaters (which should be unaffected by downstream contaminant sources), (ii.) a tributary routed through an abandoned mining district, (iii.) a binational tributary that flows though highly urbanized areas, (iv.) effluent from the local wastewater treatment plant, and (v.) the downstream confluence of the first four sources. The Soil and Water Assessment Tool (SWAT) model will be used in combination with field data to identify key sources of contaminants, contributing areas, and transport modes to track their movement to surface waters. These data will be used together to test relationships between

    Full Text Available Tomato production through the technique of grafting aims to control soil pathogens, induce flowering, and improve tolerance to waterlogging, salinity and alkalinity of the soil. For this work were performed 50 grafts for each type of rootstock, totaling 100 slips and 50 seedlings kept as control. After 15 days of grafting, the seedlings were evaluated on the percentage of picks grafting. The treatment which used the tomato cultivar Cherry Red® as rootstock presented results of vegetative growth (height and volume Cup higher than other treatments. However after transplanting, defective development was observed for plants with grafting when compared to the controls. After 35 days of follow up, there was a low survival rate, being 5% of the plants. According to the results obtained in this work the tomato cultivar Santa Cruz Kada® has good compatibility with the rootstock cultivar Cayenne® pepper and tomato cultivar Cherry Red®

  20. Blaming Machismo: How the Social Imaginary is Failing Men with HIV in Santa Cruz, Bolivia.

    Science.gov (United States)

    Heckert, Carina

    2017-01-01

    Drawing from an ethnography of HIV care in Santa Cruz, Bolivia, in this article I explore how the social imaginary surrounding gender relations shapes men's experiences of seeking care for and living with HIV. Popular understandings of gender relations, which draw heavily on the machismo concept, intersect with a global health master narrative that frames women as victims in the AIDS epidemic in a way that generates a strong sentiment of blaming machismo within local HIV/AIDS-related services. Statements such as, "it's because of machismo" are used to explain away epidemiological trends. Participant observation in the context of HIV care, coupled with illness narrative interviews, illuminate how blaming machismo shapes men's experiences of care and the ways that they feel excluded from various forms of support. Thus, the illness experiences of men with HIV problematize the machismo concept and how it is drawn upon in the context of care.

    1980-01-01

    North-central Santa Cruz County is underlain mainly by folded sedimentary rocks of Tertiary and Cretaceous age that have been highly fractured by movements in the San Andreas fault system. Ground water is stored in fractures within shale and mudstone formations and in intergranular pore spaces within fine- to very fine-grained sandstone and siltstone formations. Fewer than 10% of the wells yield more than 15 gallons of water per minute. The water in most wells is moderately hard to very hard, is generally of a sodium bicarbonate or calcium bicarbonate type, and commonly has excessive concentrations of iron or manganese. Of the many geologic units in the study area, only the Purisima Formation of Pliocene age has the potential to sustain well yields greater than 100 gallons per minute. (USGS)

    To describe the process of approval and implementation of a comprehensive smoke-free law in the province of Santa Fe, Argentina, between 2005 and 2009. Review of the Santa Fe smoke-free legislation, articles published in local newspapers and documentation on two lawsuits filed against the law, and interviews with key individuals in Santa Fe. Efforts to implement smoke-free policies in Santa Fe began during the 1990s without success, and resumed in 2005 when the provincial Legislature approved the first 100% smoke-free subnational law in Argentina. There was no strong opposition during the discussions within the legislature. As in other parts of the world, pro-tobacco industry interests attempted to block the implementation of the law using well known strategies. These efforts included a controversy media campaign set up, the creation of a hospitality industry association and a virtual smokers' rights group, the introduction of a counterproposal seeking modification of the law, the challenge of the law in the Supreme Court, and the proposal of a weak national bill that would 'conflict' with the subnational law. Tobacco control advocates sought media attention as a strategy to protect the law. Santa Fe is the first subnational jurisdiction in Latin America to have enacted a comprehensive smoke-free policy following the recommendations of the World Health Organization (WHO) Framework Convention on Tobacco Control. After 3 years of implementation, pro-tobacco industry forces failed to undermine the law. Other subnational jurisdictions in Argentina, as well as in Mexico and Brazil are following the Santa Fe example.

  5. Determining the annual periodicity of growth rings in seven tree species of a tropical moist forest in Santa Cruz, Bolivia

    To determine the annual periodicity of growth rings in seven tree species from a tropical moist forest in Santa Cruz, Bolivia, a fire scar was used as a marker point to verify the annual nature of tree rings. The number of tree rings formed between the 1995 fire scar and the collection of the cross sections in 2002 was visually identified. The seven species showed annual growth rings. In most cases, boundaries between rings were marked by the presence of marginal parenchyma and wall-thick ed fibers formed at the end of the growing season. Growth lenses and false rings were recorded in some species. Tree rings can be carefully used in Santa Cruz forests to determine rates of growth. This information is crucial for defining forest management practices in tropical regions. (Author) 21 refs.

    2015-01-01

    Current legislation transferred public tertiary hospitals in Bolivia from the Municipalities to the Regional Level. However, the Regional Governments are experiencing technical and financial constraints to reform infrastructure, modernize equipment and introduce reforms to allow better governance, management and sustainability of these hospitals. This articles summarizes the recent experience of the Government of Santa Cruz de la Sierra in Bolivia where five tertiary hospitals and blood bank (most of them in precarious working conditions) has been transferred in 2012 from the Municipal Government of Santa Cruz (the capital) to the Regional Government of Santa Cruz. To face the challenges, the Regional Government of Santa Cruz implement several improvements, such as contract new clinical and administrative personal, increases hospital budgetary autonomy, outsource hospitals' auxiliary services, take measures to eliminate waiting lists and make several new investments to modernize and equip the hospitals. The World Bank was contracted to evaluated the future financial sustainability of these investments and to advice the Government to propose changes to increase the hospitals' management performance. The article describes the remaining challenges in these hospitals and the proposals from the World Bank Study. In the area of quality of care, the main challenge is to improve client satisfaction and continuous outcomes monitoring and evaluation according quality standards. In the area of financing, the challenge is how to assure the sustainability of these hospitals with the current level of health financing and the insufficient financial transfers from the National Government. In the area of Governance, reforms to streamline and simplify internal processes need to be introduced in order to establish mechanisms to increase transparency and accountability, allowing the hospital to have a good administration and adequate participation of the main actors in the guidance of

    Full Text Available The objective of this work was to identify and interpret the entomologic perception of students and teachers living in the Santa Cruz do Xingu, Médio Araguaia region. Semistructured interviews were carried out in December 2006 with students and teachers of the basic and intermediate levels, as well as in Youth and Adult Education, in the municipality of Santa Cruz do Xingu, Mato Grosso. Of the living beings perceived as “insects” by all the interviewees, 82.75% belonged to the Insecta Class, but the rest belonged either to the Fungi Kingdom or to Classes of Animalia (Amphibia, Arachnida, Chilopoda, Diplopoda, Gastropoda, Mammalia and Reptilia. The “insects” were defined by the interviewees as small bugs, which were disgusting and dangerous. When in contact with the “insects”, 76% of the interviewees admitted that they killed them, and the greatest reason given for this was the psychological damage caused by the presence of these animals (65%. To 78% of those interviewed, the “insects” were beings without positive importance. Due to the scarce knowledge about their positive aspects, the perception of the “insects” by the students and teachers living in the Santa Cruz do Xingu region is mainly related to their belief in the negative qualities of these animals, causing aggressive reactions against them as soon as they are perceived in the environment.

    2011-01-01

    It is not uncommon to have several rare and listed taxa occupying habitats in one landscape or management area where conservation amounts to defense against the possibility of further loss. It is uncommon and extremely exciting, however, to have several listed taxa occupying one island that is managed cooperatively for conservation and recovery. On Santa Cruz Island, the largest of the northern California island group in the Santa Barbara Channel, we have a golden opportunity to marry ecological knowledge and institutional "good will" in a field test of holistic rare plant conservation. Here, the last feral livestock have been removed, active weed control is underway, and management is focused on understanding and demonstrating system response to conservation management. Yet funding limitations still exist and we need to plan the most fiscally conservative and marketable approach to rare plant restoration. We still experience the tension between desirable quick results and the ecological pace of system recovery. Therefore, our research has focused on identifying fundamental constraints on species recovery at individual, demographic, habitat, and ecosystem levels, and then developing suites of actions that might be taken across taxa and landscapes. At the same time, we seek a performance middle ground that balances an institutional need for quick demonstration of hands-on positive results with a contrasting approach that allows ecosystem recovery to facilitate species recovery in the long term. We find that constraints vary across breeding systems, life-histories, and island locations. We take a hybrid approach in which we identify several actions that we can take now to enhance population size or habitat occupancy for some taxa by active restoration, while allowing others to recover at the pace of ecosystem change. We make our recommendations on the basis of data we have collected over the last decade, so that management is firmly grounded in ecological observation.

  11. Storage Capacity and Sedimentation of Loch Lomond Reservoir, Santa Cruz, California, 1998

    McPherson, Kelly R.; Harmon, Jerry G.

    2000-01-01

    In 1998, a bathymetric survey was done to determine the storage capacity and the loss of capacity owing to sedimentation of Loch Lomond Reservoir in Santa Cruz County, California. Results of the survey indicate that the maximum capacity of the reservoir is 8,991 acre-feet in November 1998. The results of previous investigations indicate that storage capacity of the reservoir is less than 8,991 acre-feet. The storage capacity determined from those investigations probably were underestimated because of limitations of the methods and the equipment used. The volume of sedimentation in a reservoir is considered equal to the decrease in storage capacity. To determine sedimentation in Loch Lomond Reservoir, change in storage capacity was estimated for an upstream reach of the reservoir. The change in storage capacity was determined by comparing a 1998 thalweg profile (valley floor) of the reservoir with thalweg profiles from previous investigations; results of the comparison indicate that sedimentation is occurring in the upstream reach. Cross sections for 1998 and 1982 were compared to determine the magnitude of sedimentation in the upstream reach of the reservoir. Results of the comparison, which were determined from changes in the cross-sectional areas, indicate that the capacity of the reservoir decreased by 55 acre-feet.

    Trypanosoma cruzi (Tc) infection is usually acquired in childhood in endemic areas, leading to Chagas disease, which progresses to Chagas cardiomyopathy in 20-30% of infected individuals over decades. The pathogenesis of Chagas cardiomyopathy involves the host inflammatory response to T. cruzi, in which upstream caspase-1 activation prompts the cascade of inflammatory chemokines/cytokines, cardiac remodeling, and myocardial dysfunction. The aim of the present study was to examine the association of two caspase-1 single nucleotide polymorphisms (SNPs) with cardiomyopathy. We recruited infected (Tc+, n = 149) and uninfected (Tc-, n = 87) participants in a hospital in Santa Cruz, Bolivia. Cardiac status was classified (I, II, III, IV) based on Chagas cardiomyopathy-associated electrocardiogram findings and ejection fractions on echocardiogram. Genotypes were determined using Taqman probes via reverse transcription-polymerase chain reaction of peripheral blood DNA. Genotype frequencies were analyzed according to three inheritance patterns (dominant, recessive, additive) using logistic regression adjusted for age and sex. The AA allele for the caspase-1 SNP rs501192 was more frequent in Tc+ cardiomyopathy (classes II, III, IV) patients compared to those with a normal cardiac status (class I) [odds ratio (OR) = -2.18, p = 0.117]. This trend approached statistical significant considering only Tc+ patients in class I and II (OR = -2.64, p = 0.064). Caspase-1 polymorphisms may play a role in Chagas cardiomyopathy development and could serve as markers to identify individuals at higher risk for priority treatment.

    Acute respiratory infections represent a serious public health issue worldwide but virological aetiologies of Influenza Like Illnesses (ILIs) remain largely unknown in developing countries. This study represents the first attempt to characterise viral aetiologies of ILIs in Bolivia. It was performed in Santa Cruz city from January 2010 to September 2012, based on 564 naso-pharyngeal swabs collected in a National Reference Laboratory and real-time PCR techniques, viral cultures and phylogenetic analyses. 50.2% of samples were positive for at least one virus with influenza viruses (Flu A: ~15%; Flu B: ~9%), rhinoviruses (~8%), coronaviruses (~5%) and hRSV (~4%) being the most frequently identified. The pattern of viral infections varied according to age groups. The elucidation rate was the highest (>60%) amongst patients under 10 yo and the lowest (Bolivia in the study period, originating from Central and North America, Europe, Asia and Australia. Our results emphasise the requirement for a reinforced epidemiological and genetic follow-up of influenza and other ILIs in Bolivia to further inform the preparation of vaccines used in the region, guide vaccination campaigns and improve the medical management of patients.

    2010-01-01

    In 2004 the U.S. Geological Survey (USGS) launched the Border Environmental Health Initiative (BEHI), a major project encompassing the entire U.S.-Mexico border region. In 2009, a study of the Santa Cruz River Watershed (SCW), located in the border region of Arizona and Sonora, Mexico, was initiated as part of the BEHI. In this borderland region of the desert Southwest, human health and the ecosystems on which humans rely depend critically on limited water resources. Surface water is scarce during much of the year, and groundwater is the primary source for industrial, agricultural, and domestic use. In order to identify risks to water resources in the SCW, and the potential consequences to riparian ecosystems and ultimately human health, the USGS is using an interdisciplinary and integrative approach that incorporates the expertise of geographers, hydrologists, biologists, and geologists to track organic and inorganic contaminants and their effects from sources to sinks in sediment, water, plants, and animals. Existing groundwater and surface-water models are being used and modified to assess contaminant and sediment transport.

    Full Text Available The work was developed in the Los Amaros, the Santa Cruz river, Artemisa, Cuba. The objective was to evaluate how it influences the expansion of the agricultural frontier on riparian vegetation where the semi-deciduous mesophytic forest (BsdMe predominates. A floristic characterization was performed, identifying the effects of disturbances on the structure and composition of these forests and their relation to human disturbance. A semi-structured interview was applied to all landowners in the study area. Species richness, dominance, basal area, total number of individuals, width of the strip covered by trees and shrubs, and area without vegetation on both banks of the river, respectively were considered as variables. There are differences in the structure and patterns of diversity of the studied forest, as a result of disturbances, with the consequent reduction of species; also anthropogenic disturbances, are the main factors that explain changes in the structure of these forests. They are identified as major species: Cupania macrophylla A. Rich., Roystonea regia HBK O. F. Cook., Guarea guidonia L. Sleumer and Trichilia hirta  L. It is proposed to deepen the effect of the expansion of agriculture into other sectors of the river in interaction with local communities.

    Santa Cruz Island is the largest of the California Channel Islands and supports a diverse and unique flora which includes 9 federally listed species. Sheep, cattle, and pigs, introduced to the island in the mid-1800s, disturbed the soil, browsed native vegetation, and facilitated the spread of exotic invasive plants. Recent removal of introduced herbivores on the island led to the release of invasive fennel (Foeniculum vulgare), which expanded to become the dominant vegetation in some areas and has impeded the recovery of some native plant communities. In 2007, Channel Islands National Park initiated a program to control fennel using triclopyr on the eastern 10% of the island. We established replicate paired plots (seeded and nonseeded) at Scorpion Anchorage and Smugglers Cove, where notably dense fennel infestations (>10% cover) occurred, to evaluate the effectiveness of native seed augmentation following fennel removal. Five years after fennel removal, vegetative cover increased as litter and bare ground cover decreased significantly (P species increased at Scorpion Anchorage in both seeded and nonseeded plots. At Smugglers Cove, exotic cover decreased significantly (P = 0.0001) as native cover comprised of Eriogonum arborescensand Leptosyne gigantea increased significantly (P < 0.0001) in seeded plots only. Nonseeded plots at Smugglers Cove were dominated by exotic annual grasses, primarily Avena barbata. The data indicate that seeding with appropriate native seed is a critical step in restoration following fennel control in areas where the native seed bank is depauperate.

    Background In the context of a rapid increase of dengue cases in the Americas, a monitoring system based on systematic serological control (IgM) of patients consulting for suspected dengue was developed in Bolivia at the end of the 1990s. In the most affected city of Santa Cruz, this system was complemented by an entomological surveillance program based on periodical search for immature stages of Aedes aegypti in dwelling water-holding containers. Here, we analyze these data and describe dengue patterns over 6 years (2002–2008), highlighting the spatial distribution of patients and vectors. Methodology /Principal Findings Data mining concerned six annual epidemic cycles (2002–2008), with continuous serological and clinical results and entomological data from 16 surveys, examined at the scales of 36 urban areas and four concentric areas covering the entire city. Annual incidence varied from 0.28‰ to 0.95‰; overall incidence was higher in women and adults, and dengue dynamics followed successive periods of high (January–June) and low (July–December) transmission. Lower numbers of cases from the city center to the periphery were observed, poorly related to the more homogeneous and permanent distribution of A. aegypti. "Plant pots" were a major vector source in the city center, and "Tires" and "Odds and ends" beyond the second ring of the city. Conclusions/Significance Over the years, the increasing trend of dengue cases has been highlighted as well as its widespread distribution over the entire city, but an underestimation of the number of cases is strongly suspected. Contrary to popular belief, the city center appears more affected than the periphery, and dengue is not particularly related to waste. Interestingly, the clinical diagnosis of dengue by physicians improved over the years, whatever the gender, age and residential area of suspected cases. PMID:25706631

    The upper Santa Cruz Basin is an important groundwater basin containing the regional aquifer for the city of Nogales, Arizona. This report provides data and interpretations of data aimed at better understanding the bedrock morphology and structure of the upper Santa Cruz Basin study area which encompasses the Rio Rico and Nogales 1:24,000-scale U.S. Geological Survey quadrangles. Data used in this report include the Arizona Aeromagnetic and Gravity Maps and Data referred to here as the 1996 Patagonia Aeromagnetic survey, Bouguer gravity anomaly data, and conductivity-depth transforms (CDTs) from the 1998 Santa Cruz transient electromagnetic survey (whose data are included in appendixes 1 and 2 of this report).Analyses based on magnetic gradients worked well to identify the range-front faults along the Mt. Benedict horst block, the location of possibly fault-controlled canyons to the west of Mt. Benedict, the edges of buried lava flows, and numerous other concealed faults and contacts. Applying the 1996 Patagonia aeromagnetic survey data using the horizontal gradient method produced results that were most closely correlated with the observed geology.The 1996 Patagonia aeromagnetic survey was used to estimate depth to bedrock in the upper Santa Cruz Basin study area. Three different depth estimation methods were applied to the data: Euler deconvolution, horizontal gradient magnitude, and analytic signal. The final depth to bedrock map was produced by choosing the maximum depth from each of the three methods at a given location and combining all maximum depths. In locations of rocks with a known reversed natural remanent magnetic field, gravity based depth estimates from Gettings and Houser (1997) were used.The depth to bedrock map was supported by modeling aeromagnetic anomaly data along six profiles. These cross sectional models demonstrated that by using the depth to bedrock map generated in this study, known and concealed faults, measured and estimated magnetic

    Monitoring and characterizing the interactive effects of land use and climate on land surface processes is a primary focus of land change science, and of particular concern in arid Wells Distribution in Shallow Groundwater Areas Pumping Trends Increase Streamflow Extent Declines 27 environments where both landscapes and livelihoods can be impacted by short-term climate variability. Using a multi-observational approach to land-change analysis that included landownership data as a proxy for land-use practices, multitemporal land-cover maps, and repeat photography dating to the late 19th century, we examine changing spatial and temporal distributions of two vegetation types with high conservation value in the southwestern United States: grasslands and riparian vegetation. Our study area is the bi-national Santa Cruz Watershed, a topographically complex watershed that straddles the Sonoran Desert and the Madrean Archipelago Ecoregions. In this presentation we focus on historical changes in vegetation and land use in grasslands and riparian areas of the Madrean Ecoregion (San Raphael Valley, Cienega Creek, Sonoita), and compare changes in these areas to changes in the warmer and drier Sonoran Ecoregion. Analysis of historical photography confirms major 20th century vegetation shifts documented in other research: woody plant encroachment, desertification of grasslands, and changing riparian and xeroriparian vegetation occurred in both ecoregions following human settlement. However, vegetation changes over the past decade appear to be more subtle and some of the past trajectories appear to be reversing; most notable are recent mesquite declines in xeroriparian and upland areas, and changes from shrubland to grassland area in the Madrean ecoregion. Land cover changes were temporally variable, reflecting broad climate changes. The most dynamic cover changes occurred during the period from 1989 to 1999, a period with two intense droughts.

    The island factor in the cities of Las Palmas de Gran Canaria and Santa Cruz de Tenerife, their meteorology and the proximity to the African Continent that originates the natural particulate matter transport over the islands, cause some specific features in their air quality. The aim of this paper is to characterize the air pollution from 2000 to 2004 as exposure indicator of both cities inhabitants. 24 hour daily average variables of PM10, PM2,5, NO2, SO2 and O3 , 8 hours daily maxima moving averages of O3 y CO and 1 hour maxima of SO2, NO2, O3, CO, PM10 y PM2,5 were calculated. Daily levels of coarse particles were obtained subtracting PM2,5 from PM10. African dust events were identified. In Sta. Cruz de Tf daily means of SO2 (14.0 microg/m(3)N) and ozone levels (44.4 microg/m(3)N ) were higher than Las Palmas de GC levels (8.0 y 28.3 microg/m(3)N). Daily means of NO2 in Las Palmas de GC: 45.8 microg/m(3)N where higher than Sta. Cruz de Tf levels: 30.3 microg/m(3)N. Due to African dust outbreaks, some days in both cities exceeded 600 microg/m(3) of PM10 and 200 of PM2.5 24-h average. The air quality patterns were characterized by very high levels of African dust outbreaks that affect all PM size fractions. Different O3 seasonality exists respect European cities in addition to an urban-industrial ambient air in Sta. Cruz de TF and clearly urban in Las Palmas de GC. These results have to be considered in order to lay the foundations to suitable surveillance systems, analyse the potential impact on the Canary Islands citizens health and to get conclusions.

    Santa Cruz Island is the largest of the northern Channel Islands located off the coast of California. It is owned and managed as a conservation reserve by The Nature Conservancy and the Channel Islands National Park. The island is home to nine plant taxa listed in 1997 as threatened or endangered under the federal Endangered Species Act, because of declines related to nearly 150 years of ranching on the island. Feral livestock were removed from the island as a major conservation step, which was part of a program completed in early 2007 with the eradication of pigs and turkeys. For the first time in more than a century, the rare plants of Santa Cruz Island have a chance to recover in the wild. This study provides survey information and living plant materials needed for recovery management of the listed taxa. We developed a database containing information about historical collections of the nine taxa and used it to plan a survey strategy. Our objectives were to relocate as many of the previously known populations as possible, with emphasis on documenting sites not visited in several decades, sites that were poorly documented in the historical record, and sites spanning the range of environmental conditions inhabited by the taxa. From 2003 through 2006, we searched for and found 39 populations of the taxa, indicating that nearly 80 percent of the populations known earlier in the 1900s still existed. Most populations are small and isolated, occupying native-dominated habitat patches in a highly fragmented and invaded landscape; they are still at risk of declining through population losses. Most are not expanding beyond the edges of their habitat patches. However, most taxa appeared to have good seed production and a range of size classes in populations, indicating a good capacity for plant recruitment and population growth in these restricted sites. For these taxa, seed collection and outplanting might be a good strategy to increase numbers of populations for species

    On February 6, 2013 at 01:12:27 UTC (local time: UTC+11), a magnitude Mw 8.0 earthquake occurred 70 km to the west of Ndendo Island (Santa Cruz Island) in the Solomon Islands. The under-thrusting earthquake near a 90° bend, where the Australian plate subducts beneath the Pacific plate generated a locally focused tsunami in the Coral Sea and the South Pacific Ocean. The tsunami claimed the lives of 10 people and injured 15, destroyed 588 houses and partially damaged 478 houses, affecting 4,509 people in 1,066 households corresponding to an estimated 37% of the population of Santa Cruz Island. A multi-disciplinary international tsunami survey team (ITST) was deployed within days of the event to document flow depths, runup heights, inundation distances, sediment and coral boulder depositions, land level changes, damage patterns at various scales, performance of the man-made infrastructure and impact on the natural environment. The 19 to 23 February 2013 ITST covered 30 locations on 4 Islands: Ndendo (Santa Cruz), Tomotu Noi (Lord Howe), Nea Tomotu (Trevanion, Malo) and Tinakula. The reconnaissance completely circling Ndendo and Tinakula logged 240 km by small boat and additionally covered 20 km of Ndendo's hard hit western coastline by vehicle. The collected survey data includes more than 80 tsunami runup and flow depth measurements. The tsunami impact peaked at Manoputi on Ndendo's densely populated west coast with maximum tsunami height exceeding 11 m and local flow depths above ground exceeding 7 m. A fast tide-like positive amplitude of 1 m was recorded at Lata wharf inside Graciosa Bay on Ndendo Island and misleadingly reported in the media as representative tsunami height. The stark contrast between the field observations on exposed coastlines and the Lata tide gauge recording highlights the importance of rapid tsunami reconnaissance surveys. Inundation distance and damage more than 500 m inland were recorded at Lata airport on Ndendo Island. Landslides were

    In order to explore the reasons for the apparent discrepancy between laboratory and field weathering rates and to determine the extent to which weathering rates are controlled by the approach to thermodynamic equilibrium, secondary mineral precipitation and flow rates, a multicomponent reactive transport model (CrunchFlow) was used to interpret soil profile development and mineral precipitation and dissolution rates at the 226 ka marine terrace chronosequence near Santa Cruz, CA. Aqueous compositions, fluid chemistry, transport, and mineral abundances are well characterized (White et al., 2008, GCA) and were used to constrain the reaction rates for the weathering and precipitating minerals in the reactive transport modeling. When primary mineral weathering rates are calculated with either of two experimentally determined rate constants, the nonlinear, parallel rate law formulation of Hellmann and Tisser and [2006] or the aluminum inhibition model proposed by Oelkers et al. [1994], modeling results are consistent with field-scale observations when independently constrained clay precipitation rates are accounted for. Experimental and field rates, therefore, can be reconciled at the Santa Cruz site. Observed maximum clay abundances in the argillic horizons occur at the depth and time where the reaction fronts of the primary minerals overlap. The modeling indicates that the argillic horizon at Santa Cruz can be explained almost entirely by weathering of primary minerals and in situ clay precipitation accompanied by undersaturation of kaolinite at the top of the profile. The rate constant for kaolinite precipitation was also determined based on model simulations of mineral abundances and dissolved Al, SiO{sub 2}(aq) and pH in pore waters. Changes in the rate of kaolinite precipitation or the flow rate do not affect the gradient of the primary mineral weathering profiles, but instead control the rate of propagation of the primary mineral weathering fronts and thus total

    In most watershed-modeling studies, flow is calibrated at one monitoring site, usually at the watershed outlet. Like many arid and semi-arid watersheds, the main reach of the Santa Cruz watershed, located on the Arizona-Mexico border, is discontinuous for most of the year except during large flood events, and therefore the flow characteristics at the outlet do not represent the entire watershed. Calibration is required at multiple locations along the Santa Cruz River to improve model reliability. The objective of this study was to best portray surface water flow in this semiarid watershed and evaluate the effect of multi-gage calibration on flow predictions. In this study, the Soil and Water Assessment Tool (SWAT) was calibrated at seven monitoring stations, which improved model performance and increased the reliability of flow, in the Santa Cruz watershed. The most sensitive parameters to affect flow were found to be curve number (CN2), soil evaporation and compensation coefficient (ESCO), threshold water depth in shallow aquifer for return flow to occur (GWQMN), base flow alpha factor (Alpha_Bf), and effective hydraulic conductivity of the soil layer (Ch_K2). In comparison, when the model was established with a single calibration at the watershed outlet, flow predictions at other monitoring gages were inaccurate. This study emphasizes the importance of multi-gage calibration to develop a reliable watershed model in arid and semiarid environments. The developed model, with further calibration of water quality parameters will be an integral part of the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM), an online decision support tool, to assess the impacts of climate change and urban growth in the Santa Cruz watershed.

  11. Description of a New Galapagos Giant Tortoise Species (Chelonoidis; Testudines: Testudinidae from Cerro Fatal on Santa Cruz Island.

    Directory of Open Access Journals (Sweden)

    Nikos Poulakakis

    Full Text Available The taxonomy of giant Galapagos tortoises (Chelonoidis spp. is currently based primarily on morphological characters and island of origin. Over the last decade, compelling genetic evidence has accumulated for multiple independent evolutionary lineages, spurring the need for taxonomic revision. On the island of Santa Cruz there is currently a single named species, C. porteri. Recent genetic and morphological studies have shown that, within this taxon, there are two evolutionarily and spatially distinct lineages on the western and eastern sectors of the island, known as the Reserva and Cerro Fatal populations, respectively. Analyses of DNA from natural populations and museum specimens, including the type specimen for C. porteri, confirm the genetic distinctiveness of these two lineages and support elevation of the Cerro Fatal tortoises to the rank of species. In this paper, we identify DNA characters that define this new species, and infer evolutionary relationships relative to other species of Galapagos tortoises.

    Dog overpopulation and diseases are hazards to native island species and humans on the Galapagos. Vaccination and importation of dogs are prohibited on the Galapagos. Risk management of these hazards requires the use of science-based risk assessment and risk communication. The objectives of the study reported here were (i) to estimate the human:dog ratio and (ii) the prevalence of and identify exposure factors associated with positive antibody titers to canine distemper virus (CDV) and other pathogens, as well as infection with intestinal parasites in owned dogs on Santa Cruz Island, Galapagos in September 2014. The observed human:dog ratio was 6.148:1 which extrapolates to 2503 dogs (two times more than a recent dog count conducted by Galapagos Biosecurity Agency in March 2014). The proportion of spayed female dogs (50%) was higher, compared to neutered male dogs (30%) (p=0.04). Prevalence of dogs with positive antibody titers to CDV was 36% (95% CI=26, 46%), to canine parvovirus was 89% (95% CI=82, 95%), and to canine adenovirus was 40% (95% CI=30, 51%). The frequency of seropositive dogs to CDV was lower in urban dogs (26%), compared to rural dogs (53%) (pdog population on Santa Cruz is susceptible to an outbreak of CDV (particularly among urban dogs) with potential spill over to marine mammals. Dog's age (1-2 or 3-14 years old, compared to younger dogs), and residence (rural, urban) were associated with positive antibody titers to parvovirus, adenovirus, Ehrlichia spp., or Anaplasma spp., as well as infection with Ancylostoma spp., an intestinal parasite in dogs that can be transmitted to humans, particularly children. These results provide the most comprehensive assessment of dog overpopulation and exposure to CDV and other pathogens on the Galapagos to date. Copyright © 2015 Elsevier B.V. All rights reserved.

    2011-01-01

    This report summarizes the development of a binational vegetation map developed for the Santa Cruz Watershed, which straddles the southern border of Arizona and the northern border of Sonora, Mexico. The map was created as an environmental input to the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM) that is being created by the U.S. Geological Survey for the watershed. The SCWEPM is a map-based multicriteria evaluation tool that allows stakeholders to explore tradeoffs between valued ecosystem services at multiple scales within a participatory decision-making process. Maps related to vegetation type and are needed for use in modeling wildlife habitat and other ecosystem services. Although detailed vegetation maps existed for the U.S. side of the border, there was a lack of consistent data for the Santa Cruz Watershed in Mexico. We produced a binational vegetation classification of the Santa Cruz River riparian habitat and watershed vegetation based on NatureServe Terrestrial Ecological Systems (TES) units using Classification And Regression Tree (CART) modeling. Environmental layers used as predictor data were derived from a seasonal set of Landsat Thematic Mapper (TM) images (spring, summer, and fall) and from a 30-meter digital-elevation-model (DEM) grid. Because both sources of environmental data are seamless across the international border, they are particularly suited to this binational modeling effort. Training data were compiled from existing field data for the riparian corridor and data collected by the NM-GAP (New Mexico Gap Analysis Project) team for the original Southwest Regional Gap Analysis Project (SWReGAP) modeling effort. Additional training data were collected from core areas of the SWReGAP classification itself, allowing the extrapolation of the SWReGAP mapping into the Mexican portion of the watershed without collecting additional training data.

    Heavy metals are persistent environmental contaminants, and transport of metals into the environment poses a threat to ecosystems, as plants and wildlife are susceptible to long-term exposure, bioaccumulation, and potential toxicity. We investigated the distribution and cascading extent of heavy metal accumulation in southwestern song sparrows (Melospiza melodia fallax), a resident riparian bird species that occurs along the US/Mexico border in Arizona’s upper Santa Cruz River watershed. This study had three goals: (1) quantify the degree of heavy metal accumulation in sparrows and determine the distributional patterns among study sites, (2) compare concentrations of metals found in this study to those found in studies performed prior to a 2009 international wastewater facility upgrade, and (3) assess the condition of song sparrows among sites with differing potential levels of exposure. We examined five study sites along with a reference site that reflect different potential sources of contamination. Body mass residuals and leukocyte counts were used to assess sparrow condition. Birds at our study sites typically had higher metal concentrations than birds at the reference site. Copper, mercury, nickel, and selenium in song sparrows did exceed background levels, although most metals were below background concentrations determined from previous studies. Song sparrows generally showed lower heavy metal concentrations compared to studies conducted prior to the 2009 wastewater facility upgrade. We found no cascading effects as a result of metal exposure.

    Full Text Available The tomato is one of the most important vegetable, economical and nutritionally, around the world. For this reason the germination process in the tomato is a vital stage in the growth and development of plants. In this study, the effect of different doses of gibberellin over the germination of Santa Cruz variety tomato seeds was evaluated. The seeds were embedded for 24 hours in different concentrations of gibberellic acid, sown in a peat substrate in the screen house of the UPTC. A complete randomized design was used with 4 treatments corresponding to 0, 100, 200 and 400 mg L-1 of GAs with three replicates, for a total of 12 experimental units (EU, and each unit with 35 seeds. The treatment of 0 mg L-1 had a favorable impact on the mean germination time (GT, average speed of germination (ASG and germination percentage (GP, showing significant differences with respect to the other treatments. The seeds soaked in 400 mg L-1 of GAs presented the lowest values in the variables GT, ASG and GP, attributed to negative effect this type of hormone over this tomato variety, which delayed the death of the embryo and the seed germination.

    Full Text Available The basic sanitation comprises several services that are essential to the maintenance of people's health and well-being. The populations that have an appropriate water supply, sewage collection and treatment, proper garbage disposal, among other services, are protected from diseases and have access to a minimum comfort to live in a safe way. In spite of the importance of these services, to the extent to be characterized as “basic”, several populations, national or worldwide, suffer for the lack or the complete privation of sanitation, live without access to quality water, their waste is thrown under open air and their garbage is disposed in inappropriate sites, what causes health and environmental impacts. This work is being accomplished in a community called Santa Cruz, located in Campos dos Goytacazes, RJ, and aims to carry out a survey about the local sanitary reality, especially about the quality of the water supplied to the population. 100 inhabitants of that community were interviewed and answered a questionnaire. Among the results, 22% of the interviewees consume the water that comes to their homes without any type of treatment, 47% consider the supply water as being of poor quality and 7% don't own home water tanks. After the interviews, bacteriological and physicochemical water analyses were performed in fifteen samples collected in the community. The test results indicated that the collected water was out of the drinking water standards, and therefore, inappropriate for human consumption.

    Full Text Available Rationale and Objectives: Healthcare workers are constantly exposed to the risk of occupational accidents involving biological material. Thus the aim of the study was to develop a profile of workers involved in workplace accidents with biological materials in Santa Cruz do Sul, through the number of notifications made in information systems. Methods: Transversal retrospective study with a quantitative approach; data collection was carried out between the years 2008 and 2010 from medical records in the Municipal Reference Occupational Health Unit – UMREST – containing the notification via Individual Report of Accident Notification - RINA, and/or Work Accident Communication - CAT. Results: A total of 1,263 records were analyzed during the study period. There were 13 notifications in 2008, 7 cases in 2009 and 2 in 2010. Five records had CAT, 8 had RINA and 9 had RINA and CAT. The most frequently affected professional category was the nursing technician, with the highest frequency in 2008, followed by dentists and nurses. There was a higher prevalence of female workers, with 18 cases. The most prevalent age group was 20 to 49 years old. Conclusion: The study showed that women working in the nursingprofession at the productive-age group are the ones most often affected by work accidents involving biological material during the study period. The study results raise the suspicion of underreporting of accidents with biological material, considering the number of notifications in thesetting of records found in the investigated UMREST.

  2. Use of remotely sensed imagery to map Sudden Oak Death (Phytophthora ramorum) in the Santa Cruz Mountains

    Science.gov (United States)

    Gillis, Trinka

    This project sought a method to map Sudden Oak Death distribution in the Santa Cruz Mountains of California, a coastal mountain range and one of the locations where this disease was first observed. The project researched a method to identify forest affected by SOD using 30 m multi-spectral Landsat satellite imagery to classify tree mortality at the canopy-level throughout the study area, and applied that method to a time series of data to show pattern of spread. A successful methodology would be of interest to scientists trying to identify areas which escaped disease contagion, environmentalists attempting to quantify damage, and land managers evaluating the health of their forests. The more we can learn about the disease, the more chance we have to prevent further spread and damage to existing wild lands. The primary data source for this research was springtime Landsat Climate Data Record surface reflectance data. Non-forest areas were masked out using data produced by the National Land Cover Database and supplemental land cover classification from the Landsat 2011 Climate Data Record image. Areas with other known causes of tree death, as identified by Fire and Resource Assessment Program fire perimeter polygons, and US Department of Agriculture Forest Health Monitoring Program Aerial Detection Survey polygons, were also masked out. Within the remaining forested study area, manually-created points were classified based on the land cover contained by the corresponding Landsat 2011 pixel. These were used to extract value ranges from the Landsat bands and calculated vegetation indices. The range and index which best differentiated healthy from dead trees, SWIR/NIR, was applied to each Landsat scene in the time series to map tree mortality. Results Validation Points, classified using Google Earth high-resolution aerial imagery, were created to evaluate the accuracy of the mapping methodology for the 2011 data.

    Twenty to thirty percent of persons with Trypanosoma cruzi infection eventually develop cardiomyopathy. If an early indicator were to be identified and validated in longitudinal studies, this could enable treatment to be prioritized for those at highest risk. We evaluated cardiac and extracellular matrix remodeling markers across cardiac stages in T. cruzi infected (Tc+) and uninfected (Tc-) individuals. Participants were recruited in a public hospital in Santa Cruz, Bolivia and assigned cardiac severity stages by electrocardiogram and echocardiogram. BNP, NTproBNP, CKMB, troponin I, MMP-2, MMP-9, TIMP-1, TIMP-2, TGFb1, and TGFb2 were measured in specimens from 265 individuals using multiplex bead systems. Biomarker levels were compared between Tc+ and Tc- groups, and across cardiac stages. Receivers operating characteristic (ROC) curves were created; for markers with area under curve>0.60, logistic regression was performed. Analyses stratified by cardiac stage showed no significant differences in biomarker levels by Tc infection status. Among Tc+ individuals, those with cardiac insufficiency had higher levels of BNP, NTproBNP, troponin I, MMP-2, TIMP-1, and TIMP-2 than those with normal ejection fraction and left ventricular diameter. No individual marker distinguished between the two earliest Tc+ stages, but in ROC-based analyses, MMP-2/MMP-9 ratio was significantly higher in those with than those without ECG abnormalities. BNP, NTproBNP, troponin I, MMP-2, TIMP-1, and TIMP-2 levels rose with increasing severity stage but did not distinguish between Chagas cardiomyopathy and other cardiomyopathies. Among Tc+ individuals without cardiac insufficiency, only the MMP-2/MMP-9 ratio differed between those with and without ECG changes.

    The eastern domain of Marajo Island, in the surroundings of Santa Cruz do Arari (Para State), is occupied by holocenic sedimentary deposits, at present covered predominantly by natural grasslands. The analysis of stable carbon isotopes in organic matter of these sediments has been applied with the objective of to evaluate the paleovegetation dynamics, the retreat or the expansion of the Amazonian Forest (located in the westerner domain) over the different types of natural grasslands in Marajo Island, during Late Quaternary. From 3.60 m to 1.80 m the δ 13 C results are around -25 (reaching value up to -29 per mille) and indicate that the organic matter of these sediments are originated from C3 plants. In the interval of 1.80 m until 0.90 m all the samples present a gradual enrichment of 13 C, indicating a higher influence of C4 plants in the vegetation cover. The intermediate δ 13 C values found in those depths (from -22 per mille to -18 per mille) indicate a mixture of C3 and C4 plants with gradual increase of areas with C4 plants. From 0.90 m to the shallow layer the δ 13 C values show a tendency to more depleted values, indicating higher influence of C3 plants in the recent and present period. The results demonstrate that the vegetation dynamics was significant in the Marajo Island from the past to the present. The chronology of these events is being determined by the 14 C dating technique and possible causes (climatic, anthropogenic and/or neotectonic) for such changes investigate. (author)

    Full Text Available Thin sections of about 200 horizons or layers, representing 60 soil profiles in the coastal area and on the windward slopes of Isla Santa Cruz (Galápagos Islands were analysed. Based on the fabric and the composition of the groundmass and the presence of pedofeatures in individual layers or horizons, clusters of similar material are made and 7 units and 3 subunits distinguished. Plotting these units on a survey map gives a good insight in the spatial distribution of soil materials, expressing different combinations of parent material and precipitation. In the coastal area and the lowest slopes, with a summer dry climate, respectively reddish and greyish and brown materials with a porphyric c/f related distribution pattern and striated b-fabrics, and often with fragmented illuvial clay coatings are observed. The coarse material contains mainly holocrystalline basalt fragments, unweathered in the coastal area, or basalt derived individual minerals. The micromass has a halloysitic-smectitic composition. On the higher slopes, with a permanent moist climate, materials have also a porphyric or fine monic c/f related distribution pattern, but the b-fabric is undifferentiated and no illuvial features are present, gibbsitic features sometimes occur and the micromass consists mainly of halloysite and gibbsite. Subunits are distinguished here according to the microstructure, and the quantity and type of coarse material. Mesocrystalline basalt, often vesicular, dominates over holocrystalline, pointing to the influence of scoria. Soils on the higher slopes are more strongly weathered than those on the drier lower slopes and the coastal area. In depressions in the higher areas, materials with a yellowish or brownish grey micromass with a striated b-fabric, and well developed limpid illuvial clay coatings and impregnative iron oxide nodules occur. The micromass has a halloysite-smectite composition. Contrary to existing hypotheses the reddish soils in the

    Full Text Available The Equality Revolution in Santa Cruz (1876-1877, also known as the equality movement, was a conflict between the pairing of the common urban class and local elites who defended a development formula that championed a modern age that balanced the social values of the traditional and patriarchal society, and other local elites who benefited from the boom of free-market capitalism. The political actions of the egalitarians was influenced by the ideology of romantic socialism in its different stages and combined legal formulas with pressure from peasant militia and civil uprisings. The disruption between the project defending a selfmanaged local way of life and local/state modernization priorities led to a state of repression rarely seen in XIX century Santa Cruz society.La Revolución de Igualdad en Santa Cruz (1876-1877 o movimiento igualitario fue un conflicto entre el binomio formado por las capas plebeyas urbanas y las elites locales, defensoras de la fórmula del desarrollo que abogaba por una modernidad en equilibrio con los valores sociales de la sociedad patriarcal y tradicional, y otras elites locales, beneficiarias del auge del capitalismo de libre cambio. La actuación política de los igualitarios estuvo influenciada por las ideas del socialismo romántico en todas sus etapas y combinó formas legales con presión armada montonera y sublevación popular. El desajuste entre este proyecto de defensa de un autogestionado modo de vida local y las prioridades locales/estatales de modernización provocó una represión del mismo pocas veces vista en la sociedad cruceña en el siglo XIX.

    Full Text Available The brutal decline of the Imperial Colegio de Santa Cruz, after a bright but brief career, has spurred many papers and reflections. This one focuses on the economic factors, frequently ignored, that participated in its ruin. Indeed, the Colegio was stripped of its most precious assets by a few individuals belonging to the rising oligarchy of original settlers and conquerors' descendants, supported in turn by the highest authorities' --Real Audiencia, Real Hacienda, and even the viceroy Luis de Velasco the Elder, with whom they held family ties-- disregard and/or passive, or even active, complicity.

    Assessing the sustainability of International policy or urban development requires consideration of the impacts of these decisions on Ecosystem Services, or the values that humans receive from the ecosystem, including market-land price, environmental, and human well-being values. Hedonic modeling helps to identify the market land price, considering the price is determined by multiple factors affecting it. In U.S. portions of the bi-national Santa Cruz Watershed (SCW), situated at the Arizona-Sonora International border, natural amenities like the riparian corridor and green space have been documented as positive amenities that boost local real estate.

    Full Text Available Mortality of vertebrates was monitored on 2 roads (National Road 168; NR168 and Provincial Road 1; PR1 in Santa Fe Province (Argentina from October 2007 to August 2008. These roads differed in traffic volume and surrounding landscape management conditions. We also investigated the influence of environmental variables (mean monthly air temperature and monthly total rainfall on the incidence of road kills. Two people monitored the roads on foot (1 000-m line transects, 3 times a month (36 samples per road. We found 2 024 vertebrate road killed specimens representing 61 species (7 amphibians, 15 reptiles, 32 birds, and 7 mammals. The toad Rhinella fernandezae was the most frequently killed species (n = 1307, 64.57%. NR168 had a higher incidence of vertebrate road kills, particularity for amphibians, whereas birds had a higher incidence of road kills on PR1. We found a positive correlation between precipitation and temperature with vertebrate road kills on PR1. We suggest that vertebrate road mortality is a very serious problem for the conservation of the biodiversity in Santa Fe Province-Argentina, therefore implementing mitigation measures will be necessary.Se estudió la mortalidad de vertebrados en 2 rutas (RP1: Ruta Provincial N° 1 y RN168: Ruta Nacional N° 168 de la Provincia de Santa Fe (Argentina desde octubre de 2007 hasta agosto de 2008.

    This project is part of a multidisciplinary effort aimed at understanding the impacts of climate variability and change on the ecological services provided by riparian ecosystems in semiarid watersheds of the southwestern United States. Valuing the environmental and recreational services provided by these ecosystems in the future requires a numerical simulation approach to estimate streamflow in ungauged tributaries as well as diffuse and direct recharge to groundwater basins. In this work, we utilize a distributed hydrologic model known as the TIN-based Real-time Integrated Basin Simulator (tRIBS) in the upper Santa Cruz and San Pedro basins with the goal of generating simulated hydrological fields that will be coupled to a riparian groundwater model. With the distributed model, we will evaluate a set of climate change and population scenarios to quantify future conditions in these two river systems and their impacts on flood peaks, recharge events and low flows. Here, we present a model confidence building exercise based on high performance computing (HPC) runs of the tRIBS model in both basins during the period of 1990-2000. Distributed model simulations utilize best-available data across the US-Mexico border on topography, land cover and soils obtained from analysis of remotely-sensed imagery and government databases. Meteorological forcing over the historical period is obtained from a combination of sparse ground networks and weather radar rainfall estimates. We then focus on a comparison between simulation runs using ground-based forcing to cases where the Weather Research Forecast (WRF) model is used to specify the historical conditions. Two spatial resolutions are considered from the WRF model fields - a coarse (35-km) and a downscaled (10- km) forcing. Comparisons will focus on the distribution of precipitation, soil moisture, runoff generation and recharge and assess the value of the WRF coarse and downscaled products. These results provide confidence in

    National Parks and other protected areas can be influenced by contamination from outside their boundaries. This is particularly true of smaller parks and those in riparian ecosystems, a habitat that in arid environments provides critical habitat for breeding, migratory, and wintering birds. Animals living in contaminated areas are susceptible to adverse health effects as a result of long-term exposure and bioaccumulation of heavy metals. We investigated the distribution and cascading extent of heavy metal accumulation in Song Sparrows (Melospiza melodia) at Tumacacori National Historic Park (TUMA) along the upper Santa Cruz River watershed in southern Arizona. This study had three goals: (1) quantify the concentrations and distributional patterns of heavy metals in blood and feathers of Song Sparrows at Tumacacori National Historic Park, (2) quantify hematocrit values, body conditions (that is, residual body mass), and immune conditions of Song Sparrows in the park (3) compare our findings with prior studies at the park to assess the extent of heavy metal accumulation in birds at downstream sites after the 2009 wastewater treatment plant upgrade, and (4) quantify concentrations and distributional patterns of heavy metals in blood and feathers of Song Sparrows among six study sites throughout the upper Santa Cruz River watershed. This study design would allow us to more accurately assess song sparrow condition and blood parameters among sites with differing potential sources of contamination exposure, and how each location could have contributed to heavy metal levels of birds in the park.

  17. Effects of environmental amenities and locational disamenities on home values in the Santa Cruz watershed: a hedonic analysis using census data

    Arora, Gaurav; Frisvold, George; Norman, Laura

    2014-01-01

    For this study, we used the hedonic pricing method to measure the effects of natural amenities on home prices in the U.S-side of the Santa Cruz Watershed. We employed multivariate spatial regression techniques to estimate how difference factors affect median home values in 613 census block groups of the 2000 Census, accounting for spatial autocorrelation, spatial lags, and/or spatial heterogeneity in the data. Diagnostic tests suggest that failure to account for the hedonic model can be classified as (1) physical features of the housing stock, (2) neighborhood characteristics, and (3) environmental attributes. Census data was combined with GIS data for vegetation and land cover, land administration, measures of species richness and open space, and proximity to amenities and disamenities. Census block groups close to the US-Mexico border of airports/air bases were negative. Results suggest that policies to maintain biodiversity and open space provide economic benefits to homeowners, reflected in higher home values. Future research will quantify the marginal effects of regression explanatory variables on home values to assess their economic and policy significant. These marginal effects will be used as input indicators to discern potential economic impacts of various scenarios in the Santa Cruz Watershed Ecosystem Portfolio Model (SCWEPM). Future research will also expand this effort into the Mexican-portion of the watershed.

    Full Text Available El presente trabajo aborda las transformaciones espaciales sufridas en los asentamientos humanos del área cordillerana de la provincia de Santa Cruz producto de la actividad turística particularmente en los del departamento Lago Argentino. El Chaltén y El Calafate son los asentamientos que desarrollan el turismo como base de su economía. El incremento de la actividad se debe a los cambios en el sistema productivo provincial en las últimas décadas, netamente ganadero en El Calafate a principios y mediados del siglo XX. Asimismo, las razones geopolíticas que dieron origen a El Chaltén, hoy han pasado a ser parte de su historia, ya que el turismo es la principal actividad que desarrolla el asentamiento. Esta actividad en la provincia se ha incrementado a partir de la década del 1990 impulsada por los Estados nacional, provincial y municipal que llevan adelante políticas de promoción en el sector. Por otra parte, en estos asentamientos, el auge turístico trae aparejado consecuencias sociales y ambientales dado el crecimiento acelerado de los mismos en cuanto a la población que se radica, la falta de infraestructura básica y equipamiento son los principales sin dejar de mencionar la especulación inmobiliaria. El objetivo del presente trabajo es analizar las transformaciones espaciales en los asentamientos del oeste de la provincia de Santa Cruz particularmente los del departamento Lago Argentino a partir del incremento de la actividad turística en el área en las últimas décadas. Teóricamente, se recurrió a Roberto C. Boullón en Planificación del espacio turístico, a diferentes apuntes de Eduardo Salinas Chávez, y a Leslie Scovenna en el Gran Libro de Santa Cruz entre otras. Se utilizaron diversas páginas en Internet información proporcionada por la Subsecretaria de Turismo de la Provincia de Santa Cruz.

Dicho análisis permitió su diferenciación cualitativa y la identificación de los aportes que ocasiona cada uno de ellos. En éste trabajo se ha procedido en primer lugar a determinar la calidad de los vertidos y del agua del arroyo a partir de una escala de valoración. Dicha escala se confeccionó usando las conclusiones del análisis estadístico mencionado y la comparación de los valores obtenidos con los límites máximos de vuelco establecidos para la provincia de Santa Cruz (ley N° 2658, los Niveles guía argentinos de calidad de agua ambiente y los Niveles guía de la ley de protección Ambiental Nº 24585 (Código de minería argentino. Finalmente para valorar el impacto ocasionado por los efluentes minero industriales, se tomó en consideración además de la calidad, otros factores relevantes tales como caudal, tipo de vertido, intermitencia y peligrosidad; adoptando un modelo matemático particular que permitió asignar un puntaje asociado a una escala cualitativa. Como conclusión se pudo determinar mediante una metodología científica que el impacto ocasionado por las descargas minero industrial de carbón al curso de agua varía en un rango de alto a muy alto y esta determinada principalmente por aquellas provenientes de la planta depuradora de carbón y la central térmica.

  20. High Resolution Mapping of an Alleged Chemical Weapons Dump Site in the Santa Cruz Basin, offshore California

    Nautical charts record seven locations off the coast of California labeled as 'Chemical Munitions Dumping Area, Disused' that together cover some 12,000 km2 of sea floor. However only one such chemical munitions site is officially documented and no record exists of any chemical munitions disposed of at other locations, thus creating confusion. We have executed a one day AUV mapping survey of a corner of one such site in the Santa Cruz Basin, south of Port Hueneme, to examine and investigate the debris field. The region is covered with soft sediment and the overlying water is very low in oxygen at ~10 μmol/kg. The processed 110 kHz sidescan data revealed some 754 targets in 25.6 km2 for an average of 29 targets per km2. This was followed by two ROV dives to investigate the targets identified. We found but one false positives among the over 40 targets visited, and found items ranging from two distinct lines of unmarked or labeled and now empty barrels, two target drones, and much miscellaneous debris including 4-packs of cat food cans and a large ships mast over 30m in length. There was zero evidence of chemical weapons materiel as expected given the lack of official records. Almost all of the targets were covered in dense and colorful assemblages of invertebrates: sponges, anemones, and crabs. Where barrels were sufficiently open for full visual inspection, the interior sea floor appeared to have become fully anoxic and was covered in white and yellow bacterial mat. The area chosen for our survey (centered at 33.76 deg N 119.56 deg W) was across the north western boundary of the marked site, and represents only ~ 10% percent of the designated area. Our expectation, that human nature would drive the disposal activities to the nearest corner of the chosen area rather than the center of the field appears to have been confirmed. Objects were found both within and outside of the boundary of the dump site. We have not surveyed the full marked area but there appears to be

    In the present paper, zinc sheets have been exposed for 4 years to the action of different atmospheres in 35 test sites located in the province of Santa Cruz de Tenerife, Canary Islands, Spain. Corrosion products formed on the surface of the samples have been identified by means of X-ray diffraction (XRD) for the first and second year of exposure. Zincite, hydrozincite, simonkolleite, zinc chlorohydroxysulphate, zinc oxysulphate and zinc hydroxysulphate have been identified in the test sheets. Preliminary results of an electrochemical study of the breakdown potential of zinc samples are also presented in order to test the protective effect of the film formed on the surface of the samples. It was found that the protective effect of this film increases linearly with exposure time.

    Among approximately 2,000 mammals examined for helminths in various regions of Bolivia during 1983-1987, cysts of Echinococcus vogeli Rausch and Bernstein, 1972, were found in a single paca, Cuniculus paca L., collected at La Laguna, Departamento de Santa Cruz (lat. 16 degrees 36'W; long. 62 degrees 42'S). This record, the first from Bolivia, represents a considerable extension of the known geographic range of this species in South America. Upon analysis of the morphologic characteristics of the protoscoleces derived from the cysts, the sizes of rostellar hooks from the material from the paca were found to be well within the ranges reported in previous studies. Statistical analysis of frequency distributions of hook characteristics revealed some deviations from normality. These results indicate that parametric statistics should be applied with caution in analyses of inter-and intraspecific variation of morphologic characteristics of hooks of metacestodes of the genus Echinococcus.

    Samples of ground drill cores from the southern part of the Santa Cruz porphyry copper deposit, Casa Grande, Arizona, were oxidized in simulated weathering experiments. The samples were also separated into various mineral fractions and analyzed for contents of metals and sulfide minerals. The principal sulfide mineral present was pyrite. Gases produced in the weathering experiments were measured by gas chromatography. Carbon dioxide, oxygen, carbonyl sulfide, sulfur dioxide and carbon disulfide were found in the gases; no hydrogen sulfide, organic sulfides, or mercaptans were detected. Oxygen concentration was very important for production of the volatiles measured; in general, oxygen concentration was more important to gas production than were metallic element content, sulfide mineral content, or mineral fraction (oxide or sulfide) of the sample. The various volatile species also appeared to be interactive; some of the volatiles measured may have been formed through gas reactions. ?? 1990.

    To estimate the frequency of and risk factors for surgical-site infections (SSIs) in Bolivia, and to study the performance of the National Nosocomial Infections Surveillance (NNIS) System risk index in a developing country. A prospective study with patient follow-up until the 30th postoperative day. A general surgical ward of a public hospital in Santa Cruz, Bolivia. Patients admitted to the ward between July 1998 and June 1999 on whom surgical procedures were performed. Follow-up was complete for 91.5% of 376 surgical procedures. The overall SSI rate was 12%. Thirty-four (75.6%) of the 45 SSIs were culture positive. A logistic regression model retained an American Society of Anesthesiologists score of more than 1 (odds ratio [OR], 1.87), a not-clean wound class (OR, 2.28), a procedure duration of more than 1 hour (OR, 1.81), and drain (OR, 1.98) as independent risk factors for SSI. There was no significant association between the NNIS System risk index and SSI rates. However, a "local" risk index constructed with the above cutoff points showed a linear trend with SSI (P < .001) and a relative risk of 3.18 for risk class 3 versus a class of less than 3. SSIs cause considerable morbidity in Santa Cruz. Appropriate nosocomial infection surveillance and control should be introduced. The NNIS System risk index did not discriminate between patients at low and high risk for SSI in this hospital setting, but a risk score based on local cutoff points performed substantially better.

    Full Text Available The present work studies the relations between historians and political elite in Santa Fe, Argentina, in the middle of the decade of 1930. From data relieved in journalistic articles of the epoch arises that they were linked by marriage. The family relations became vital when Manuel María of Iriondo arrived to provincial government and was proposed to restore a government of the “better”. This political project conditioned the writing of the history and some of the main members of the recently created Junta de Estudios Históricos occupied the role of organic intellectuals endowing of prestige to the main families of the network. The past was a factor of internal cohesion for the political elite and a source of recognition of its domination on the society of Santa Fe.

    Full Text Available Fundamento: El carácter insular de las ciudades de Las Palmas de Gran Canaria y Santa Cruz de Tenerife, su meteorología y la proximidad del continente africano que favorece la llegada de material particulado de origen natural sobre las islas, determinan unas especificidades en su calidad del aire. El objetivo de este artículo es la caracterización de la contaminación atmosférica durante los años 2000 a 2004 como indicador de exposición de los habitantes de estas dos ciudades. Métodos: Se elaboraron los siguientes indicadores de contaminación: promedios de 24 horas de PM10, PM2,5, NO2, SO2 y O3; máximo de las 17 medias móviles octohorarias diarias de O3 y CO; máximo horario diario de SO2, NO2, O3, CO, PM10 y PM2,5. También se calcularon los niveles de la moda gruesa de partículas, como la diferencia entre los valores de PM10 y PM2,5 (PM10-2,5. Se identificaron episodios de intrusión africana. Resultados: En Sta Cruz de TF los promedios de SO2 (14ug/m3N y de O3 (44,4 ug/m3N fueron superiores respecto a los de Las Palmas de GC (8 y 28,3 ug/m3N. Los promedios de NO2 en Las Palmas de GC: 45,8 ug/m3N fueron superiores a los de Sta. Cruz de TF: 30,3 ug/m3N. Debido a las intrusiones africanas, algunos días superaron los 600 ug/m3 de PM10 y los 200 de PM2.5 en ambas ciudades. Conclusiones: Se identifica un patrón de calidad del aire con episodios de polvo mineral africano que en superficie afecta a todas las fracciones granulométricas, una estacionalidad diferente a las ciudades europeas respecto al ozono, así como un patrón de contaminación urbano-industrial en Sta.

Overuse of broad spectrum insecticides affects the action of natural enemies of this insect on cabbage. The objectives of this work were to identify the parasitoids of P. xylostella and to determine their influence on larva and pupa mortality. Weekly collections of larvae and pupae were randomly conducted in cabbage crops during spring 2006 and 2007. The immature forms collected were classified according to their developmental stage: L1 and L2 (Ls = small larvae, L3 (Lm = medium larvae, L4 (Ll = large larvae, pre-pupae and pupae (P. Each individual was observed daily in the laboratory until the adult pest or parasitoid emergence. We identified parasitoids, the number of instar and the percentage of mortality of P. xylostella for each species of parasitoid. Parasitoids recorded were: Diadegma insulare (Cresson, 1875 (Hymenoptera, Ichneumonidae, Oomyzus sokolowskii (Kurdjumov, 1912 (Hymenoptera, Eulophidae, Cotesia plutellae (Kurdjumov, 1912 (Hymenoptera, Braconidae and an unidentified species of Chalcididae (Hymenoptera. Besides parasitoids, an unidentified entomopathogenic fungus was also recorded in 2006 and 2007. In 2006, the most successful parasitoids were D. insulare and O. sokolowskii, while in 2007 only D. insulare exerted a satisfactory control and it attacked the early instars of the pest.

  15. Processes of Terrace Formation on the Piedmont of the Santa Cruz River Valley During Quaternary Time, Green Valley-Tubac Area, Southeastern Arizona

    Lindsey, David A.; Van Gosen, Bradley S.

    2010-01-01

    In this report we describe a series of stepped Quaternary terraces on some piedmont tributaries of the Santa Cruz River valley in southeastern Arizona. These terraces began to form in early Pleistocene time, after major basin-and-range faulting ceased, with lateral planation of basin fill and deposition of thin fans of alluvium. At the end of this cycle of erosion and deposition, tributaries of the Santa Cruz River began the process of dissection and terrace formation that continues to the present. Vertical cutting alternated with periods of equilibrium, during which streams cut laterally and left thin deposits of channel fill. The distribution of terraces was mapped and compiled with adjacent mapping to produce a regional picture of piedmont stream history in the middle part of the Santa Cruz River valley. For selected tributaries, the thickness of terrace fill was measured, particle size and lithology of gravel were determined, and sedimentary features were photographed and described. Mapping of terrace stratigraphy revealed that on two tributaries, Madera Canyon Wash and Montosa Canyon Wash, stream piracy has played an important role in piedmont landscape development. On two other tributaries, Cottonwood Canyon Wash and Josephine Canyon Wash, rapid downcutting preempted piracy. Two types of terraces are recognized: erosional and depositional. Gravel in thin erosional terraces has Trask sorting coefficients and sedimentary structures typical of streamflood deposits, replete with bar-and-swale surface topography on young terraces. Erosional-terrace fill represents the channel fill of the stream that cuts the terrace; the thickness of the fill indicates the depth of channel scour. In contrast to erosional terraces, depositional terraces show evidence of repeated deposition and net aggradation, as indicated by their thickness (as much as 20+ m) and weakly bedded structure. Depositional terraces are common below mountain-front canyon mouths where streams drop their

In the last 20 years, excavation of some important historical sites has allowed the development of Historical Archaeology. As an example, we comment some results obtained from the excavation of the floor of the church of Our Lady of the Conception, where the deads of Santa Cruz de Tenerife were interred during centuries. Despite the poor preservation of the skeletons, it has been possible to infer dietary habits, toxic exposure, nutritional status and genetic lineages (mitochondrial DNA. Smoking pipes, ceramics and adornments associated with interments show a high similitude with those from colonial sites of the New World.

    Riparian ecosystems in arid environments provide critical habitat for breeding, migratory, and wintering birds, yet are often at risk of contamination by heavy metals. Birds and other animals living in contaminated areas are susceptible to adverse health effects as a result of long-term exposure and bioaccumulation of heavy metals. We investigated the distribution and cascading extent of heavy metal accumulation in Song Sparrows (Melospiza melodia) in Arizona’s upper Santa Cruz River watershed. This study had three goals: (1) quantify the degree of heavy metal accumulation in sparrows and determine the distributional patterns among study sites, (2) compare concentrations of metals found in this study to those found in studies performed prior to the 2009 international wastewater treatment plant upgrade, and (3) assess sparrow condition among sites with differing potential sources of contamination exposure. We examined six study sites that reflected different potential sources of contamination. Hematocrit values, body mass residuals, and leukocyte counts were used to assess sparrow condition. Cadmium, copper, mercury, nickel, and selenium exceeded background concentrations at some sites, but generally were lower than or similar to concentrations found in earlier studies performed prior to the 2009 international wastewater treatment plant upgrade. Concentrations were higher in recaptured birds in 2012 than in 2011 for 7 metals in feathers and 14 metals in blood, suggesting possible bioaccumulation. We found no cascading effects as a result of heavy metal exposure, but did find that heavy metal concentrations were reduced following the 2009 international wastewater treatment plant upgrade.

    Full Text Available The aim of this study was to verify possible differences in the levels of physical activity related to the socio-economic conditions of schoolchildren in the municipality of Santa Cruz do Sul-RS. It is of transversal-descriptive character, and its subjects are 350 schoolchildren, aged 7 to 17, of both genders. For data collection a previously validated and adapted questionnaire was used, while the chi-quadrat-test was used for statistical analysis. Significant statistical differences were detected in the manner of locomotion, with regard to the school level and socio-economic status, for both genders. The results showed that students from urban areas and of inferior socio-economic levels showed more active in this respect. In the practice of physical activities, the results pointed to a reverse relation of this variable with the socio-economic level. At school level, a prevalence of inactive subjects from the rural area was observed. The difference in the form of locomotion and the physical activities of the evaluated schoolchildren, both at school level and at their socio-economic level, demonstrates different profiles of schoolchildren, which should be considered in future intervention programs.

    We present eleven Apatite Fission Track (AFT) and Apatite (U-Th)/He (A-He) analyses and eighteen catchment-averaged cosmogenic 10Be denudation rates from the Santa Cruz Mountains (SCM) that resolve the unroofing history of this range over the past several Myr. This range lies within a restraining bend in the San Andreas Fault (SAF), which appears to be fixed to the crust on the northeast side of the fault based on previous work. In this view, the topographic asymmetry of the SCM reflects the advection of material southwest of the right-lateral SAF through a zone of uplift centered on the restraining bend, while material northwest of the fault remains trapped this zone. Northeast of the fault bend in the Sierra Azul block of the SCM, AFT ages adjacent to the SAF appear completely reset during the Pliocene, and show partial resetting at the periphery of the block. This suggests that total exhumation exceeded 3-4 km within the heart of the block and was SCM are near mass flux steady state over the timescales captured by the CRN (~1.5-6.5 ka). Nonetheless, the extent of topography in areas far from the bend suggests that there may be some component of regional fault-normal contraction and/or that this steady state has not been fully attained because of geomorphic lags and isostatic adjustments.

  5. Ethnoastronomy in the Multicultural Context of the Agricultural Colonies in Northern Santa Fe Province, Argentina

    Mudrik, Armando

    In this paper, we present a study about cultural astronomy among European colonists and their Argentinean descendants, in the context of a complex interaction between criollos, aboriginals and European colonists from different origins and religions, who settled in the northern area of the Argentinean province of Santa Fe, which is part of the southern Gran Chaco. These colonists arrived among waves of immigration occurring in Argentina in the second half of the nineteenth century and the first half of the twentieth century. Through ethnographic field research among these immigrants and their descendants, we carried out a survey of their astronomical representations and practices, and the connections of these with their social life and farming tasks. Through this we gained an insight as to how the astronomical ideas of immigrants, criollos and aboriginal groups influenced each other, generating a variety of new relations with the celestial realm.

    It is generally accepted that material collected by leaf-cutting ants of the genus Acromyrmex consists solely of plant matter, which is used in the nest as substrate for a symbiotic fungus providing nutrition to the ants. There is only one previous report of any leaf-cutting ant foraging directly on fungal basidiocarps. Basidiocarps of Psilocybe coprophila growing on cow dung were actively collected by workers of Acromyrmex lobicornis in Santa Fé province, Argentina. During this behaviour the ants displayed typical signals of recognition and continuously recruited other foragers to the task. Basidiocarps of different stages of maturity were being transported into the nest by particular groups of workers, while other workers collected plant material. The collection of mature basidiocarps with viable spores by leaf-cutting ants in nature adds substance to theories relating to the origin of fungiculture in these highly specialized social insects.

    Leptospirosis is a global and re-emerging zoonotic disease caused by Leptospira spirochetes that are shed into the environment by infected animals. Humans can get infected via contact with animal hosts or contaminated environment. In Argentina, the highest annual incidences were reported in the province of Santa Fe, where epidemic outbreaks occurred during flooding events. This study examined the knowledge, attitudes and practices (KAP) regarding leptospirosis among residents of riverside slum settlements from Santa Fe after a major flood. A cross-sectional questionnaire was administered to 113 residents of 3 riverside settlements from Santa Fe. The influence of knowledge and attitudes regarding leptospirosis on the likelihood that an individual will use preventive practices were evaluated using linear mixed-effects models. The majority of respondents (83.2%) had previously heard about leptospirosis; however specific knowledge about leptospirosis was limited. The results of the modeling efforts, show that the likelihood of using preventive practices was associated with having greater knowledge score, but not with more positive attitudes. We also found that females were more likely to use safer practices than males. Even though the majority of respondents had heard about leptospirosis, a high percentage of them had limited knowledge regarding the severity of the disease and its prevalence in the region. Our results suggest that public health interventions in these riverside communities should focus on educating the public on the multiple dimensions of leptospirosis in order to attain greater adherence to preventive practices instead of intending to change the perceptions or attitudes towards the disease, which did not have a significant influence. The key challenge lies in identifying effective strategies to reach the high risk group for leptospirosis here that is male fishermen, who spend most of the time in precarious campsites on the river islands.

    Intimate partner violence is widespread worldwide. While assumed to impact women's ability to use contraceptive methods, few data are available to support this claim. In this study, eight focus group discussions were conducted to guide questionnaire development and to provide contextual information. Participants were women who were currently using the pill and women who had used the pill previously. In addition, 300 women were interviewed who initiated oral contraceptive pill use between December 1995 and April 1996. Participants were interviewed 3-6 months later to investigate the role intimate partner violence played in covert pill use and pill discontinuation. Special study procedures for asking women questions about violence were employed. Nineteen per cent of the women interviewed were using the pill covertly. The odds of covert pill use were four times higher in El Alto and La Paz than in Santa Cruz. Women who used the pill covertly were more likely to have experienced method-related partner violence (OR = 21.27) than women whose partners knew of their pill use. One-third of the women had discontinued pill use at the time of the interview. In the final multivariate analysis, having experienced side-effects (OR = 2.37) was a significant predictor of pill discontinuation and method-related partner violence was marginally predictive (OR = 1.91; 95% CI 1.0-3.66). While efforts are ongoing to incorporate men into family planning programmes, some male partners oppose, and in some situations violently oppose, contraceptive use. The needs of women with these types of partners must not be overlooked.

    An assessment of self-efficacy and social capital may have the potential to detect an effect of dynamic, complex and comprehensive collective actions in community-based health promotion. In 2003, a healthy village project was launched in Santa Cruz, Bolivia with technical assistance from the Japan International Cooperation Agency (JICA). The originally developed FORSA (Fortalecimiento de Redes de Salud) model accounted for participatory processes in which people could improve their health and well-being through individual behavioral changes and family/community-driven activities. This study aimed to examine the extent of self-efficacy and social capital obtained via project activities by a cross-sectional analysis. We randomly selected 340 subjects from the healthy village project site and 113 subjects from a control area. Both groups were interviewed using the same structured questionnaire. Self-efficacy was assessed with a General Self-Efficacy Scale (GSES), while social capital was measured as the frequency of formal group participation in community meetings during the past three months, perceived social solidarity, and general trust. The study results showed that the participants in the project site had higher self-efficacy and social capital compared to those in the control site. The number of times a subject participated in the health committee activities was positively associated with the self-efficacy scale. Regarding social capital, females and lower-educated people were more likely to have had more frequent participation in formal groups; males and higher-educated participants showed less formal group participation, but more generosity to contribute money for the community. The main perceived benefit of participation in formal group activities varied among individuals. The findings suggest that people in the healthy village project site have higher self-efficacy, especially those with active participation in the health committee activities. To recruit

    Starch gel electrophoresis was used for examining the transferrin gene locus (Tf) and two esterase gene loci (Est-1 and Est-D1) of a pirarucu (Arapaima gigas) population sample collected from Santa Cruz Lake, Tefé River, Amazonas, Brazil. The Tf locus was tentatively classified as being polymorphic, showing two double-banded patterns (Tf(12) and Tf(22)) of the three theoretically expected ones (Tf(11), Tf(12) and Tf(22)), presumably controlled by two co-dominant alleles, Tf(1) and Tf(2). The monotony detected in pirarucu Tf locus genotypes showing a very high proportion of the double-banded heterozygote pattern Tf(12) (95% of the sampled individuals) may indicate the possibility of their having come from representatives of the same brood begotten by a pair of fish, where a single-banded Tf(11) homozygote pattern male would have crossed with a single-banded Tf(22) homozygote pattern female, or vice versa. One zone of electrophoretic activity was detected in esterase, presumably controlled by a monomorphic Est-1 locus with the fixed allele Est-1(1) where all individuals showed the single-banded Est-1(11) homozygote pattern. Esterase-D also displayed one zone of electrophoretic activity, presumably controlled by a monomorphic Est-D1 locus with a fixed allele Est-D1(1) where all individuals revealed the single-banded Est-D1(11) genotype pattern. The monotony comprised by single-banded genotype patterns in both esterase systems tested may also indicate the possibility of the individuals from the sample examined having come from representatives of the same brood begotten by a pair of fish with both the male and female having the same genotypes.

    A wide range of insecticide resistance profiles has been reported across Bolivian domestic and sylvatic populations of Triatoma infestans (Klug, 1834) (Hemiptera, Reduviidae), including some with levels proven to be a threat for vector control. In this work, the insecticide profile of domestic T. infestans was studied with standardized toxicological bioassays, in an area that has not undergone consistent vector control. F1 first-instar nymphs hatched in laboratory from bugs captured in three communities from the Santa Cruz Department were evaluated with different insecticides. Moreover, the enzymatic activity of esterases and cytochrome P450 monooxygenases was measured in individual insects to evaluate the possible mechanism of metabolic resistance to pyrethroids. In addition, the DNA sequence of sodium channel gene (kdr) was screened for two point mutations associated with pyrethroid resistance previously reported in T. infestans.All populations showed reduced susceptibility to deltamethrin and α-cypermethrin, albeit the RR50 values varied significantly among them. Increased P450 monooxygenases and permethrate esterases suggest the contribution, as detoxifying mechanisms, to the observed resistance to deltamethrin in all studied populations. No individuals presented either mutation associated to resistance in the kdr gene. The level of susceptibility to α-cypermethrin, the insecticide used by the local vector control program, falls within an acceptable range to continue its use in these populations. However, the observed RR50 values evidence the possibility of selection for resistance to pyrethroids, especially to deltamethrin. Consequently, the use of pyrethroid insecticides should be closely monitored in these communities, which should be kept under entomological surveillance and sustained interventions. © The Authors 2016.

  20. The impact of biotic/abiotic interfaces in mineral nutrient cycling: A study of soils of the Santa Cruz chronosequence, California

    Biotic/abiotic interactions between soil mineral nutrients and annual grassland vegetation are characterized for five soils in a marine terrace chronosequence near Santa Cruz, California. A Mediterranean climate, with wet winters and dry summers, controls the annual cycle of plant growth and litter decomposition, resulting in net above-ground productivities of 280-600gm -2yr -1. The biotic/abiotic (A/B) interface separates seasonally reversible nutrient gradients, reflecting biological cycling in the shallower soils, from downward chemical weathering gradients in the deeper soils. The A/B interface is pedologically defined by argillic clay horizons centered at soil depths of about one meter which intensify with soil age. Below these horizons, elevated solute Na/Ca, Mg/Ca and Sr/Ca ratios reflect plagioclase and smectite weathering along pore water flow paths. Above the A/B interface, lower cation ratios denote temporal variability due to seasonal plant nutrient uptake and litter leaching. Potassium and Ca exhibit no seasonal variability beneath the A/B interface, indicating closed nutrient cycling within the root zone, whereas Mg variability below the A/B interface denotes downward leakage resulting from higher inputs of marine aerosols and lower plant nutrient requirements.The fraction of a mineral nutrient annually cycled through the plants, compared to that lost from pore water discharge, is defined their respective fluxes F j,plants=q j,plants/(q j,plants+q j,discharge) with average values for K and Ca (F K,plants=0.99; F Ca,plants=0.93) much higher than for Mg and Na (F Mg,plants 0.64; F Na,plants=0.28). The discrimination against Rb and Sr by plants is described by fractionation factors (K Sr/Ca=0.86; K Rb/K=0.83) which are used in Rayleigh fractionation-mixing calculations to fit seasonal patterns in solute K and Ca cycling. K Rb/K and K24Mg/22Mg values (derived from isotope data in the literature) fall within fractionation envelopes bounded by inputs from

  1. Off-fault ground ruptures in the Santa Cruz Mountains, California: Ridge-top spreading versus tectonic extension during the 1989 Loma Prieta earthquake

    Ponti, Daniel J.; Wells, Ray E.

    1991-01-01

    The Ms 7.1 Loma Prieta earthquake of 18 October 1989 produced abundant ground ruptures in an 8 by 4 km area along Summit Road and Skyland Ridge in the Santa Cruz Mountains. Predominantly extensional fissures formed a left-stepping, crudely en echelon pattern along ridges of the hanging-wall block southwest of the San Andreas fault, about 12 km northwest of the epicenter. The fissures are subparallel to the San Andreas fault and appear to be controlled by bedding planes, faults, joints, and other weak zones in the underlying Tertiary sedimentary strata of the hanging-wall block. The pattern of extensional fissures is generally consistent with tectonic extension across the crest of the uplifted hanging-wall block. Also, many displacements in Laurel Creek canyon and along the San Andreas and Sargent faults are consistent with right-lateral reverse faulting inferred for the mainshock. Additional small tensile failures along the axis of the Laurel anticline may reflect growth of the fold during deep-seated compression. However, the larger ridge-top fissures commonly have displacements that are parallel to the north-northeast regional slope directions and appear inconsistent with east-northeast extension expected from this earthquake. Measured cumulative displacements across the ridge crests are at least 35 times larger than that predicted by the geodetically determined surface deformation. These fissures also occur in association with ubiquitous landslide complexes that were reactivated by the earthquake to produce the largest concentration of co-seismic slope failures in the epicentral region. The anomalously large displacements and the apparent slope control of the geometry and displacement of many co-seismic surface ruptures lead us to conclude that gravity is an important driving force in the formation of the ridge-top fissures. Shaking-induced gravitational spreading of ridges and downslope movement may account for 90¿ or more of the observed displacements on

    The spatial and temporal changes in element and mineral concentrations in regolith profiles in a chronosequence developed on marine terraces along coastal California are interpreted in terms of chemical weathering rates and processes. In regoliths up to 15 m deep and 226 kyrs old, quartz-normalized mass transfer coefficients indicate non-stoichiometric preferential release of Sr > Ca > Na from plagioclase along with lesser amounts of K, Rb and Ba derived from K-feldspar. Smectite weathering results in the loss of Mg and concurrent incorporation of Al and Fe into secondary kaolinite and Fe-oxides in shallow argillic horizons. Elemental losses from weathering of the Santa Cruz terraces fall within the range of those for other marine terraces along the Pacific Coast of North America. Residual amounts of plagioclase and K-feldspar decrease with terrace depth and increasing age. The gradient of the weathering profile bs is defined by the ratio of the weathering rate, R to the velocity at which the profile penetrates into the protolith. A spreadsheet calculator further refines profile geometries, demonstrating that the non-linear regions at low residual feldspar concentrations at shallow depth are dominated by exponential changes in mineral surface-to-volume ratios and at high residual feldspar concentrations, at greater depth, by the approach to thermodynamic saturation. These parameters are of secondary importance to the fluid flux qh, which in thermodynamically saturated pore water, controls the weathering velocity and mineral losses from the profiles. Long-term fluid fluxes required to reproduce the feldspar weathering profiles are in agreement with contemporary values based on solute Cl balances (qh = 0.025-0.17 m yr-1). During saturation-controlled and solute-limited weathering, the greater loss of plagioclase relative to K-feldspar is dependent on the large difference in their respective solubilities instead of the small difference between their respective

    Full Text Available Gomphotheriidae fossil remains from shore level of Santa Clara del Mar (Mar del Plata, Argentina are described. The comparative morphological and multivariate analysis of the m3 with other South American gomphotheres remains, mainly from Argentina, Bolivia and Brazil, allow their identification as Stegomastodon platensis. This species seems better adapted to live on the middle latitudes and warm climatic conditions. The possible movement routes from north to the most austral zones or areas are discussed. Stegomastodon from South America is a big-size form which is present along the East route and in several shore areas of Ecuador and Peru. In the present work some palaeoecological and palaeogeographical considerations are included. From a radiometric AMS datum, the remains of Santa Clara del Mar are dated in the late Pleistocene (17,880 ± 60 AP.Se describen restos bien conservados de gonfoterios (Mammalia, Proboscidea encontrados en los niveles pleistocenos que afloran en los acantilados costeros de Santa Clara del Mar (Mar del Plata, Argentina.

    Palynological, palaeoparasitological and paleobotanical studies of coprolites found in archaeological sites from Perito Moreno National Park (47°57‧S72°05‧W) yielded information on diet, palaeoenvironment and health. These studies allowed adding evidence to the reconstruction of life history of the hunter-gatherers that inhabited Patagonia during the Holocene. We examined the season of the year when camelid Lama guanicoe coprolites (5400 ± 64 yr 14C BP to 9640 ± 190 yr 14C BP) were deposited at Cerro Casa de Piedra 7 (site CCP7). The study used palynological evidence and comparison with pollen spectra of modern feces collected during summer, fall, winter and spring of 2010. The dominant types were: pollen of Nothofagus, Empetrum rubrum, Asteraceae subfam. Asteroideae, Nassauvia, Caryophyllaceae and Poaceae; fern spores; remains of Eimeria macusaniensis; and plant remains of Poaceae, Festuca pallescens, Stipa speciosa, Armeria maritima, Gaultheria mucronata and E. rubrum. Pollen spectra of modern and fossil feces were used for multivariate analysis. Coprolites associated to fall and winter modern feces. These results and those obtained from pollen concentration values and the presence of pollen types indicators of seasonality, allowed the determination of summer, fall and winter coprolites. However, caution must be taken with the seasonality results of coprolites dated earlier than 9000 years BP since the environmental conditions differed from now. The site was probably a camelid shelter during the unfavorable seasons.

    As a result of ongoing changes in climate, hydrologic and ecologic effects are being seen across the western United States. A regional study of how climate change affects water resources and habitats in the San Francisco Bay area relied on historical climate data and future projections of climate, which were downscaled to fine spatial scales for application to a regional water-balance model. Changes in climate, potential evapotranspiration, recharge, runoff, and climatic water deficit were modeled for the Bay Area. In addition, detailed studies in the Russian River Valley and Santa Cruz Mountains, which are on the northern and southern extremes of the Bay Area, respectively, were carried out in collaboration with local water agencies. Resource managers depend on science-based projections to inform planning exercises that result in competent adaptation to ongoing and future changes in water supply and environmental conditions. Results indicated large spatial variability in climate change and the hydrologic response across the region; although there is warming under all projections, potential change in precipitation by the end of the 21st century differed according to model. Hydrologic models predicted reduced early and late wet season runoff for the end of the century for both wetter and drier future climate projections, which could result in an extended dry season. In fact, summers are projected to be longer and drier in the future than in the past regardless of precipitation trends. While water supply could be subject to increased variability (that is, reduced reliability) due to greater variability in precipitation, water demand is likely to steadily increase because of increased evapotranspiration rates and climatic water deficit during the extended summers. Extended dry season conditions and the potential for drought, combined with unprecedented increases in precipitation, could serve as additional stressors on water quality and habitat.

    Highlights: • Study on inorganic arsenic species in groundwater for drinking in Santa Fe Argentina. • This information is currently scarce or absent in the region. • An analytical methodology based on SPE-FI-HGAAS coupling was used for speciation. • Information is given for a more accurate interpretation of the toxicological impact. - Abstract: The distribution of inorganic arsenic species in groundwater used as drinking water supply by the peri-urban and rural population from central-western area of Santa Fe Province, Argentina, was studied. An analytical methodology based on an online system of atomic absorption spectrometry with hydride generation and flow injection (FI-HGAAS) was used for total inorganic arsenic determination. For speciation purposes, the distinction between As(V) and As(III) was performed through the on line coupling of FI-HGAAS to a solid phase system based on an anionic exchanger able to retain As(V) as oxyanion, allowing As(III) to be selectively determined. The concentration of As(V) was calculated as the difference between total arsenic and As(III) concentrations. Effects of matrix interference due to the nonselective behavior of the exchange resins were carefully laid. Results for 59 samples collected from 27 localities showed an almost exclusive predominance of pentavalent forms

    Studies have reported the relationship between the excessive intake of saturated fatty acids (SFA) and trans fatty acids (t-FA) and an increased risk of cardiovascular disease. Since 2006, the MERCOSUR countries require that the mandatory nutrition labeling should include information not only about the content of SFA but also about the content of t-FA. This does not apply to fractionated products at the point of retail, such as bakery products. This paper aimed to determine the total fat content and the fatty acid profile in unpackaged traditional bakery products (breads, biscuits and pastries) in Santa Fe, Argentina. Except for French bread, the contribution of t-FA and SFA to the total FA consumption from baked products was high. On the other hand, due to the high variability detected in the FA composition of bakery products between bakeries, it would be necessary to implement regulations making nutrition labeling mandatory in these products.

    The Hazel Dell site provides the first definitive paleoseismic evidence of two pre-1906 19th century events on the Santa Cruz Mountains section based on the presence of anthropogenic artifacts. Hundreds of pieces of cut redwood chips were found in a stratigraphic horizon just below the ante-penultimate (E3) earthquake surface, suggesting that redwood trees at the site were cut down right before earthquake E3. We correlate our paleoseismic findings with the historic record and the onset of redwood logging in the area by determining the felling date of a buried redwood tree stump at the site and the age of the woodchips. We wiggle match 14 radiocarbon dates sampled from annual growth rings taken from the stump and the known interval between growth rings, with the intercepts of the INTCAL04 terrestrial 14C calibration curve. Pending 13C measurements, we find that the youngest ring we have identified in the tree is A.D. 1800. We also wiggle match 2 radiocarbon dates from inner and outer growth rings from two wood chips (with bark); their ages are consistent with the tree and the youngest woodchip ring is dated to 1813 A.D. There are no known ethnographic or historical accounts of pre-contact native people felling large trees in the way that European colonists did. The first record of European land use was for pasture in 1803. The property became a Spanish land grant in 1827, soon after which a whip-saw lumber mill is documented to have begun operation in the upper Corralitos area. We combine these paleoseismic results with historical earthquake accounts for the area and conclude that the San Andreas fault ruptured in 1838, 1890 and 1906. The Hazel Dell results are in contrast with findings from earlier paleoseismic studies in the Santa Cruz Mountains. The Grizzly Flat site, 6 km to the north, found evidence of 1906 and one 17th century earthquake. Two historic earthquakes were observed at the Mill Canyon site 8 km to the south and at the Arano Flat site 9.5 km south of

Os resultados obtidos permitiram identificar que em uma situação na qual qualquer um destes efluentes fosse lançado neste corpo receptor, mesmo que de forma isolada, resultaria em sérios prejuízos ambientais decorrentes de efeitos agudos e crônicos. A baixa vazão deste recurso hídrico reduz por conseqüência a sua capacidade de suportar impactos deste tipo, denunciando uma completa incompatibilidade entre as atividades geradoras destes resíduos e o ecossistema local. Assim, a alternativa para compatibilizar estes fatores passa pela otimização de processos industriais e a implantação de políticas voltadas ao reuso de águas no processo, de forma a minimizar o volume de efluente gerado e a sua ecotoxicidade.

    A geophysical survey involving seismic refraction tomography (SRT for mapping 'P' waves was carried out in Sierra Santa Clara, San Juan Province, Argentina in July 2009. The purpose of the geophysical survey was to determine the degree of fracturing and the rigidity of the rock mass through which it is planned to build a 290 m long road tunnel traversing the mountain almost perpendicular to the axis thereof, at around 100 m depth from the summit.

    Several difficulties arose from the operational point of view which made it almost impossible to conduct fieldwork in normal circumstances. Firstly, the topography had almost 45° slopes and 100 m research depths which would have involved having had to use explosives to generate seismic waves reaching sensors which had sufficient signal-to-noise ratio for distinguishing them. Legal restrictions regarding the use of explosives on the one hand and insufficient power when using hammer blows on the other made it necessary to design and build a gas-powered gun to achieve the minimum energy (2 kJ required for detecting seismic signals.

    Secondly, using conventional interpretation methods involving layered models was inoperable in such geological structures; seismic tomography methods were thus used which make use of the velocity gradient concept (both lateral and in-depth. This allowed mapping subsurface velocity variations in the form of velocity contour lines.

    The methodology used with the new seismic waves' source generator, as well as SRT application in this type of geological structure, demonstrated that satisfactory results could be obtained for this kind of geophysical study for geotechnical purposes.

Se presentan los estudios realizados en relación con este brote y los intentos de identificación de la fuente y del modo de transmisión. Los hallazgos epidemiológicos, serológicos y clínicos indicaron que el agente causal fue Leptospira interrogans. Como prueba de tamizaje se aplicó la técnica de aglutinación macroscópica con antígeno termorresistente, seguida de la prueba de ELISA y, como prueba de confirmación, la aglutinación microscópica frente a 10 serovariedades de L. interrogans. Se estudiaron 32 individuos, 8 perros y 8 muestras de agua. Se registraron 12 casos confirmados, 2 probables y 18 negativos. En seis perros se demostró la existencia de infección y en las muestras de agua se detectó la presencia de espiroquetas móviles. Los sueros humanos reaccionaron con las serovariedades ballum, canicola, icterohaemorrhagiae y pyrogenes, y los caninos con ballum, canicola y pomona. La coaglutinación observada en todos los casos confirmados indica que se trató de casos agudos de leptospirosis, pero no permite identificar la serovariedad causal. Salvo en el caso índice, no se reconoció clínicamente la enfermedad. Varios hechos sugieren que la causa del brote fue la inundación pluvial de la zona estudiada.

    Full Text Available OBJETIVO: Caracterizar desde los puntos de vista epidemiológico, clínico y de laboratorio los casos y brotes de triquinelosis que se registraron en la provincia de Santa Fe, Argentina, entre 1998 y 2009. MÉTODOS: Se analizaron 1 519 fichas epidemiológicas de personas que presentaron síntomas y signos compatibles con triquinelosis en la provincia de Santa Fe en el período 1998-2009. Se realizó el análisis estadístico descriptivo de la información contenida en las fichas epidemiológicas y los resultados clínicos y de laboratorio; se aplicó el análisis bifactorial para determinar las posibles asociaciones con factores epidemiológicos y ambientales. RESULTADOS: Se encontraron síntomas de triquinelosis en 1 276 casos; 372 cumplían la definición de caso clínico y 224 muestras resultaron positivas por inmunofluorescencia indirecta, independientemente de su clasificación como caso clínico. Se identificaron 27 brotes que involucraron a 1 157 casos en ocho departamentos, con mayor frecuencia en el centro y el sur de la provincia. La distribución anual de los casos asociados epidemiológicamente entre sí fue heterogénea, con una mayor frecuencia en el período 2000-2003 y en los meses de agosto a octubre. Hubo mayor probabilidad de enfermar cuando se consumieron productos de fuentes informales (OR = 3,69; P = 0,014 y en las áreas rurales (OR = 1,799; P = 0,011. El período de incubación de la enfermedad (mediana fue de 12 días. Las personas que consumieron carne de cerdo o sus derivados tuvieron 2,06 veces más riesgo de enfermar que las que no la consumieron. CONCLUSIONES: El mayor número de brotes ocurrió en los departamentos más poblados y con mayor producción porcina. Se deben diseñar acciones específicas de prevención y control de la enfermedad en esos departamentos. Se debe considerar el análisis epidemiológico de riesgos al evaluar, gestionar y comunicar los riesgos sanitarios de triquinelosis.OBJECTIVE: To

    Radiometric surveys are a rapid tool to measure uranium (U), thorium (Th) and potassium (K) concentrations in rocks and are very useful in the exploration for radioactive minerals. The distribution of uranium in Jurassic volcanic rocks of the province of Santa Cruz is evaluated in this work using ground gamma-ray spectrometry and rock geochemistry in order to assess its potential to form uranium deposits. Five areas were selected, which had some previous data of high radiometric values and detailed geological information. Measurements were carried out with a portable gamma-ray spectrometer (Exploranium-GR 320®) in andesites, ignimbrites, rhyolites, silicified areas, ash-fall tuffs and lacustrine sediments corresponding to the Bahía Laura and to El Quemado complexes. The results were similar in the five surveyed areas: radiometric concentrations show good positive correlations with chemical composition of the studied rocks for both K and Th, and a relatively poorer correlation for U. Different processes such as magmatic differentiation, vapor phase crystallization, hydrothermal alteration and supergene alteration are reflected in the distribution of these elements. U concentrations increase in the more glassy rocks, in areas with hydrothermal silicification, and in fracture zones, features that should be considered in future surveys. The calkalkaline composition and arc-signatures of the Jurassic magmatism are not the most favorable for uranium enrichment and for concentration of significant mineralizations. However, the extensional tectonic setting; the occurrence of calderas with facies slightly enriched in U and Th, in addition to hydrothermal activity are positive factors for U exploration.

La demanda de agua que se generará a partir de los planes de expansión de la actividad productiva y la que se originará por el aumento poblacional, hace necesario que se realicen acciones para recuperar cursos afectados, tomando como punto de partida la identificación y caracterización de efluentes descargados. Los estudios realizados previamente se han basado en un tratamiento global o en muestreos puntuales sin difereciar, cuantificar o cualificar en forma sistemática las alteraciones ocasionadas por los distintos aportes. En éste trabajo se identificó los diferentes vertidos al arroyo y se determinó parámetros fisicoquímicos durante dos campañas (invierno y verano que permitieron caracterizar los individuos a partir de un tratamiento estadístico multivariado de los datos. Los resultados arrojaron valores de pH dentro del rango de la neutralidad o ligeramente básicos y la alcalinidad, otro de los factores que determinan la disolución de metales, dio valores que les confiere a las aguas capacidad amortiguadora beneficiosa. Como conclusión estadística general, los efluentes quedaron diferenciados principalmente entre los que aportan importantes cantidades de sólidos y metales totales en suspención (Planta depuradora de carbón y la Central térmica, de los que no lo hacen (Minas en explotación y abandonadas y efluentes Poblacionales.

    This discussion of Argentina covers geography, the people, history and political conditions, government, economy, foreign relations, and relations between the US and Argentina. In 1985, the population of Argentina was estimated to be 30.6 million with an estimated annual growth rate of 1.5%. The infant mortality rate is 34.1/1000, and life expectancy is 70.2 years. Argentina, which shares land borders with Bolivia, Brazil, Chile, Paraguay, and Uruguay, is bounded by the Atlantic and the Antarctic Oceans. Descendants of Italian and Spanish immigrants predominate in Argentina, but many trace their origins to British and West and East European ancestors. In recent years, there has been a substantial influx of immigrants from neighboring Latin American countries. The native Indian population, estimated to be 50,000, is concentrated in the peripheral provinces of the north, northwest, and south. What is now Argentina was discovered in 1516 by the Spanish navigator Juan de Solia. The formal declaration of independence from Spain was made on July 9, 1816. In the late 19th century, 2 forces worked to create the modern Argentine nation: the introduction of modern agricultural techniques and the integration of Argentina into the world economy. Argentina has impressive human and natural resources, but political conflict and uneven economic performance since World War II have impeded full realization of its considerable potential. Yet, it is one of the wealthiest countries in Latin America. Among the reasons for the military coup of March 1976 was the deteriorating economy, caused by declining production and rampant inflation. Under the leadership of the Minister of the Economy, the military government focused attention on those immediate problems, and, in 1978, embarked on a new development strategy focusing on the establishment of a free market economy. There was little improvement in the economy, and a new economic plan was introduced in 1985 which has capped inflation by

  5. The exploitation of obsidian in the Central Plateau of Santa Cruz, Argentina: Results from La María and Cerro Tres Tetas and a regional perspective

    Results from this work strengthen the idea that the groups which lived in the Central Plateau knew about and exploited an obsidian source known as Pampa del Asador. A raise in the use of this raw material throughout time is recorded, reaching its peak in the late Holocene. We identified two different moments in the exploitation of obsidian at the regional level. During the final Pleistocene and early Holocene, obsidian would not have played a relevant role in the organization of technology. Production sequences indicate that tools probably were entered to the sites already manufactured. During the middle and late Holocene nodules and cores could have been brought into the sites. The strategies involved in their reduction are in broad terms similar to those implemented with local raw materials; there is no evidence that obsidian had more value in any way. On the other hand, it is also not possible to state that there was just an eventual exploitation of this raw material. We believe that obsidian was acquired during mobility circuits which enabled the contact between different groups.

    Work for the coming year is a logical continuation of the efforts of the past year. Some special highlights of this past year which are discusses in more detail in this report are: (1) The move onto beamline and start of ZEUS data taking. (2) The completion of the SDC technical proposal including a detailed long-term plan for construction. (3) Continuing publication of very detailed physics results from ALEPH concerning τ and b physics, and a precision measurement of electroweak and QCD parameters. (4) Completion of very successful data taking for E-791 at Fermilab, with nearly twice as many events recorded as initially proposed. (5) First measurement of beam polarization at the SLC. These efforts have led to about 15 physics publications this past year centered mainly on topics related to QCD, couplings of flavors to the Z degrees, and heavy flavor decays. Taken as a whole, the results in jets from LEP, the ratio of hadronic to leptonic decays of the τ the leptonic branching fraction of the J/ψ, and the charmonium mass spectrum provide a very consistent set of values of α s at a variety of scales. In particular, they show the running of α s by a factor of about three from m r to m z . Results from LEP also provide evidence of the triple gluon vertex. Similarly, the measurement of the b bar b fraction of Z degrees decays, from the MARK II as well as LEP, provide increasingly better measurements of the Z degree coupling to b quarks. Combined with earlier precision measurements of the Z degrees mass, width, and leptonic branching fractions, the Z degrees decays continue to provide a very precise verification of the Standard Model

    Argentina has embarked on an ambitious domestic nuclear research and energy program. The venture promises to provide the nation with the infrastructure to play an important role in the nuclear export market in the years ahead. Buenos Aires built its program on a foundation of international support and assistance that overlay an emerging sophisticated industrial and scientific establishment. The foreign contribution sensitized Argentina to opportunities in the global market. This paper reports that Argentina operates two heavy-water/natural uranium reactors, Atucha I and Embalse. Producing, respectively, 320 MW(e) and 600 MW(e), they supply roughly 10 percent of the country's electricity. With a capacity factor of 84 percent, Atucha I is among the best operated plants in the world. Plans call for a third, 745 MW(e) power plant, Atucha II, to go on line in the early 1990s. During this period, construction also may begin on three 300 MW(e) plants, although the country's foreign indebtedness plus cost overruns in earlier construction will place a heavy burden on these plans

    Tumacácori National Historical Park protects the culturally important Mission, San José de Tumacácori, while also managing a portion of the ecologically diverse riparian corridor of the Santa Cruz River. This report describes the methods and quality assurance procedures used in the collection of water samples for the analysis of Escherichia coli (E. coli), microbial source tracking markers, suspended sediment, water-quality parameters, turbidity, and the data collection for discharge and stage; the process for data review and approval is also described. Finally, this report provides a quantitative assessment of the quality of the E. coli, microbial source tracking, and suspended sediment data.The data-quality assessment revealed that bias attributed to field and laboratory contamination was minimal, with E. coli detections in only 3 out of 33 field blank samples analyzed. Concentrations in the field blanks were several orders of magnitude lower than environmental concentrations. The microbial source tracking (MST) field blank was below the detection limit for all MST markers analyzed. Laboratory blanks for E. coli at the USGS Arizona Water Science Center and laboratory blanks for MST markers at the USGS Ohio Water Microbiology Laboratory were all below the detection limit. Irreplicate data for E. coli and suspended sediment indicated that bias was not introduced to the data by combining samples collected using discrete sampling methods with samples collected using automatic sampling methods.The split and sequential E. coli replicate data showed consistent analytical variability and a single equation was developed to explain the variability of E. coli concentrations. An additional analysis of analytical variability for E. coli indicated analytical variability around 18 percent relative standard deviation and no trend was observed in the concentration during the processing and analysis of multiple split-replicates.

    This paper reports that like so many other countries, Argentina is in the throes of privatization and restructuring of its economic programs. This has had a direct effect on the LPG industry. Argentina is a country with many natural resources. However, natural gas and crude, while present, are not in abundance. Imports of these and their associated products are needed to satisfy the growing need of the population from time to time. This is especially true with LPGs. Production of the fuel averages about 1 million tons, not enough to satisfy internal needs in the winter but enough to permit some exports in the summer to nearby Brazil. The Country's Congress approved a plan to sell-off or lease parts of the natural gas distribution network and other businesses of Gas del Estado. Subsequent new legislation has called for ten new natural gas distribution zones. Included in the sell-off is the company's propane distribution division. What is left of Gas del Estado and YPF will become a corporation in the true sense of the word. Stocks in YPF are to be sold to the public

    Background notes on Argentina provide a profile of the geography, selected demographic features, government and economic conditions. Descriptive text includes a discussion of the people, their history and political conditions, the government and officials, the state of the economy, their defense, foreign relations, and relations with the US. The 1992 estimated population was about 33 million of whom 97% are European (mostly Spanish and Italian). Religions represented are Roman Catholic (92%), Protestant (2%), Jewish (2%), and other (4%). Adult literacy is 95%. 36% are engaged in industry and commerce, 20% in services, 19% in agriculture, 6% in transport and communications, and 19% other. Per capita gross domestic product was $4,500. There are only 50,000 native Indians remaining in peripheral provinces. The population enjoys a high standard of living and a low growth rate. The country was shaped by dominant forces: modern agricultural techniques and the integration of the country into the world economy. Foreign investment aided the economic revolution. Conservative and radical rule has swung the country back and forth politically since 1916. Colonel Juan Domingo Peron led a successful military coup in 1943 and was elected in 1946. Policies were instituted to give a greater voice to the working class, and with the influences of his wife, women's groups. In 1955, he was ousted by the military, which failed to revive the economy and quiet increasing terrorism. After a number of difficult elections, Peron was reinstated as president in 1973. Extremists on the left and right threatened public order; the military as a consequence imprisoned persons indefinitely. Peron's wife succeeded him after his death, but was removed from office in the military coup of 1976. Basic human rights were violated during this period. By 1983, a fair election was held and support increased for a democratic system. In 1989, Carlos Saul Menem, a Peronist candidate, won and established

    Full Text Available RESUMEN Se presentan modelos de aptitud para el desarrollo de la agricultura prehispánica y actual en un sector del valle de Santa María (Catamarca, Argentina, a través de la aplicación de técnicas de evaluación multicriterio con Sistemas de Información Geográfica. La base cartográfica fue conformada a partir de imágenes satelitales en combinación con mapas de elaboración acerca de unidades geomorfológicas, provincias fitogeográficas, hidrografía y áreas con evidencia arqueológica de agricultura prehispánica. Se observó que el área con mayor potencial para la agricultura se ubica en el sector pedemontano de la sierra del Aconquija, seguido por el fondo de valle. Este patrón coincide principalmente con el registro arqueológico prehispánico, pero no con la distribución espacial de las explotaciones agrícolas actuales. La relación entre la sociedad y la naturaleza, mediatizada a través de la tecnología, se presenta como la clave de interpretación. ABSTRACT This study was performed with the objective to identify suitable areas for development of pre-Hispanic and contemporary agriculture in Santa Maria Valley (Catamarca, Argentina through the application of multicriteria evaluation techniques using Geographic Information Systems. The base map was based on data obtained from satellite images in combination with thematic maps specially prepared about geomorphological units, phytogeographic provinces, hydrography and areas with archaeological evidence of prehispanic agriculture. It was observed that the area with the greatest potential for agriculture is located in the piedmont sector of the Aconquija mountain, followed by the bottom of the valley. This pattern coincides mainly with the pre-Hispanic archaeological record, but not with the spatial distribution of existing farms. The relationship between society and nature, mediated through technology, is presented as the key to interpretation

    Full Text Available Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA is increasingly recognized as an important pathogen causing skin and soft tissue infections as well as necrotizing pneumonia. We describe a case of familial transmission of CA-MRSA between a 6-month-old boy and his mother in Santa Fe City, Argentina. Both isolates showed an identical antimicrobial susceptibility profile, carried type IV SCCmec and harboured the pvl and the lnu(A genes. Isolates showed indistinguishable SmaI-PFGE patterns confirming their genetic relationship. These results corroborate the intrafamilial transmission of CA-MRSA and might associate this strain with the repetitive events of furunculosis within the family.Staphylococcus aureus resistente a la meticilina adquirido en la comunidad (SARM-AC es reconocido como un patógeno importante que causa infecciones de piel y partes blandas y neumonía necrotizante. Describimos un caso de transmisión familiar de SARM-AC entre un nino de 6 meses de edad y su madre en la ciudad de Santa Fe, Argentina. Ambos aislamientos mostraron idéntico perfil de sensibilidad a los antimicrobianos, tenían el SCCmec tipo IV, y contenían los genes pvl y lnu(A. Los aislamientos presentaron patrones de SmaI-PFGE indistinguibles entre sí, lo cual confirmó su relación genética. Estos resultados corroboran la transmisión intrafamiliar de SARM-AC; asimismo, este aislamiento podría asociarse con los eventos repetitivos de furunculosis en la familia.

    Full Text Available Las serpientes son usualmente muy perseguidas por el hombre y poco consideradas en estrategias de conservación de la biodiversidad, siendo las áreas protegidas esenciales para su preservación. Se analizaron los patrones de riqueza y biogeográficos de las serpientes de Santa Fe, Argentina, para priorizar áreas para su conservación y evaluar si las reservas existentes coinciden con ellas. Los patrones de diversidad y distribución fueron establecidos mediante el análisis de 2.532 especímenes de ofidios de Santa Fe, obtenidos en muestreos de campo y revisión de colecciones, complementados con registros bibliográficos y un banco de datos regional de 8.000 ejemplares. Se determinaron las áreas de endemismos de serpientes, las que fueron comparadas con las divisiones fitogeográficas. Se dividió Santa Fe en 16 celdas de un grado de latitud y longitud, para comparar su riqueza, similitud y complementariedad, aplicándose un método para priorizar áreas de conservación según la riqueza y el valor de conservación de cada taxón. La riqueza de especies en Santa Fe aumenta con la disminución de la latitud y longitud en relación con un gradiente de aumento de temperatura y precipitaciones anuales promedio. En consecuencia las celdas ubicadas en el extremo nordeste poseen la mayor riqueza (conteniendo 84 % de las especies y las celdas ubicadas en el extremo suroeste la menor riqueza (20 %. Todas las celdas atravesadas por el río Paraná tienen una mayor riqueza que las celdas contiguas, probablemente, debido al efecto de este río como corredor de especies tropicales y subtropicales. Se definieron cinco áreas de endemismos, cuatro de ellas coinciden con una o dos divisiones fitogeográficas y son relevantes en análisis de conservación por tener especies exclusivas. El análisis de similitud entre celdas muestra tres grupos mayores, "noroeste", "noreste-centro" y "sur", que coinciden con tres áreas de endemismos. El análisis conjunto

Samples were collected between February 1999 and January 2000 from lichens and mosses growing on sidewalk trees of the urban and periurban area. Five species of tardigrades were found, i.e., Echiniscus rufoviridis du Bois-Reymond Marcus, 1944, Macrobiotus areolatus Murray, 1907, Ramazzottius oberhaeuseri (Doyère, 1840, Milnesium cf. tardigradum and a non-described species of Macrobiotus. Only one species, M. cf. tardigradum, was found in areas with high levels of vehicle traffic. Results are compared with those from cities in the Nearctic and Palearctic regions. Measurements and pt index values (percentage ratios between the length of the structure considered and the buccal tube length are provided for M. areolatus, R. oberhaeuseri and M. cf. tardigradum. Amongst the characters considered, the pt index for the stylet support insertion shows the least intraspecific variation. This character is also independent from body length and buccal-tube length.

Uno de ellos, con un registro de más de 345 m, corresponde a la Formación Mollar. El tramo inferior a medio está caracterizado por una monótona sucesión de lutitas bituminosas acumuladas por decantación suspensiva en el 'off shore' anóxico de un cuerpo lacustre hidrológicamente cerrado y que muestra alto contenido de materia orgánica amorfa de origen algal y de restos de plantas terrestres muy degradadas junto a sulfuros de hierro autígenos. Intercalan areniscas finas debidas a corrientes de turbidez diluidas y carbonatas estromatolíticos. En esta sucesión se definen ciclos granocrecientes de pequeña escala (PACs que se atribuyen a episodios de expansión-retracción lacustre controlados por cambios climáticos. Asociaciones de facies heterolíticas representan los depósitos de la transición entre los ambientes de 'nearshore' y 'offshore' lacustre. La sección superior de la Formación Mollar se compone de sucesiones pelíticas con profusa bioturbación que sugieren mayor oxigenación del sustrato y se asignan a ambiente de costa afuera de un sistema lacustre holomíctico hidrológicamente abierto. Intercalan areniscas producto de flujos hiperpicnales. Depósitos de areniscas con abundantes trazas fósiles y estructuras de olas y flujos unidireccionales, representan a sectores marginales del ambiente lacustre. Además de los ciclos de alta frecuencia, en la Formación Mollar se definen tres secuencias asimétricas de mayor escala atribuidas a episodios mayores de expansión-contracción lacustre debidos a la interacción entre factores climáticos y tectónicos. El diseño de superposición granocreciente de la Formación Mollar y la gradual transición a depósitos fluviales de la sobreyacente Formación Montaña refleja asimismo una constante reducción del espacio de acomodación sedimentaria en el

A lo largo de su milenaria historia, ha sido reconocido por ser una región donde se encuentran tres ciénagas (Chignahuapan, Chimaliapan y Chicnahuapan, circundadas por volcanes y densos bosques además del río Lerma. La riqueza ambiental de este frío valle favoreció la temprana ocupación de la región, cuyas evidencias arqueológicas se remontan, por lo menos, hasta hace más de 3000 años, durante el Formativo temprano. Hacia 500/600 d. C., las condiciones climáticas se volvieron más secas, provocando el descenso del nivel de agua de las lagunas y permitiendo la colonización del interior de las ciénagas. El sitio arqueológico Santa Cruz Atizapán constituye uno de los asentamientos lacustres que se fundaron en esta zona. Este artículo se enfoca en él, donde los antiguos pobladores se adaptaron a las condiciones del terreno cenagoso y lo transformaron en un lugar habitable, construyendo unos cien montículos sobre los cuales levantaron sus casas-habitaciones. Trata, también, acerca del modo de vida lacustre, donde prevalece la relación simbiótica del hombre con su medio, y sobre el intercambio de productos con otras regiones, que destacan por considerarse de gran relevancia en el desarrollo y consolidación del sitio como centro rector.

    Desmanthus paspalaceus (Lindm.) Burkart belongs to the D. virgatus complex, subfamily Mimosoidae. The known potential as livestock fodder of several of these legumes prompted us to undertake a phenotypic, molecular, and symbiotic characterization of the D. paspalaceus symbionts in the Santa Fe province, Argentina. The rhizobia collected—containing isolates with different abiotic-stress tolerances—showed a remarkable genetic diversity by PCR fingerprinting, with 11 different amplification profiles present among 20 isolates. In selected isolates 16S-rDNA sequencing detected mesorhizobia (60%) and rhizobia (40%) within the collection, in contrast to the genus of the original inoculant strain CB3126—previously isolated from Leucaena leucocephala—that we typified here through its 16S rDNA as Sinorhizobium terangae. The results revealed the establishment by diverse bacterial genera -rhizobia, sinorhizobia, and mesorhizobia- of full N2-fixing symbiotic associations with D. paspalaceus. This diversity was paralleled by the presence of at least two different nodC allelic variants. The identical nodC alleles of the Mesorhizobia sp. 10.L.4.2 and 10.L.5.3 notably failed to group within any of the currently described rhizo-/brady-/azorhizobial nodC clades. Interestingly, the nodC from S. terangae CB3126 clustered close to homologs from common bean nodulating rhizobia, but not with the nodC from S. terangae WSM1721 that nodulates Acacia. No previous data were available on nod-gene phylogeny for Desmanthus symbionts. A field assay indicated that inoculation of D. paspalaceus with the local Rhizobium sp. 10L.11.4 produced higher aerial-plant dry weights compared to S. teranga CB3126–inoculated plants. Neither the mesorhizobia 10.L.4.2 or 10.L.5.3 nor the rhizobium 10L.11.4 induced root nodules in L. leucocephala or P. vulgaris. The results show that some of the local isolates have remarkable tolerances to several abiotic stresses including acidity, salt, and temperature

    Full Text Available En febrero de 2008 se denunció en la localidad santafecina de Las Rosas un presunto brote de una enfermedad transmitida por alimentos. En los procedimientos oficiales no fue posible determinar la cantidad de personas afectadas luego de consumir canelones de verdura adquiridos en un local comercial. Se auditó el establecimiento elaborador y se tomaron muestras del citado producto, muestras ambientales e hisopados de los manipuladores de alimentos. Se entrevistó a los afectados y se recuperaron restos del alimento ingerido. Mediante análisis microbiológicos de rutina se determinó la presencia de S. aureus subespecie aureus coagulasa positivo en muestras del producto consumido, del producto crudo y de los manipuladores del alimento. Los microorganismos indicadores no mostraron niveles significativos y no se aisló otro patógeno de transmisión alimentaria. Se investigó la presencia de genes productores de enterotoxinas estafilocócicas, con resultado positivo para la enterotoxina B en las cepas aisladas de un manipulador y en el alimento vinculado con el brote. Al analizar los aislamientos por SmaI-PFGE se demostró un 100% de similitud entre ellos. La notificación oportuna, las acciones sanitarias coordinadas y la disponibilidad de las herramientas de laboratorio apropiadas permitieron identificar los factores de protección y de riesgo, y cortar la cadena de transmisión de la enfermedad.On February 2008, a suspected foodborne outbreak was reported in Las Rosas (Santa Fe Province, Argentina.

The main cherry-growing areas are three: the Uco Valley in Mendoza province, the Los Antiguos Valley in the province of Santa Cruz and the Lower Valley of the Chubut River (VIRCH in the province of same name, which met the requirements for achieving good crop yields. The main destination of this nectarine is in addition to domestic consumption, exports to the US and the European Union (EU, representing an important trade surplus for producing areas.

    La incorporación de cultivos que no son tradicionales para la República Argentina se hizo notable a fines del siglo XX y principios del XXI por las innovaciones tecnológicas que permiten rindes muy significativos, la oportunidad que representa la exportación de algunos productos agropecuarios como es el caso de la cereza favorecidos por el tipo de cambio, y la contraestacionalidad de la producción, respecto de los mercados consumidores del hemisferio norte. Las principales zonas de cultivo de cerezo son tres: el Valle de Uco en la provincia de Mendoza, el Valle Los Antiguos en la provincia de Santa Cruz y el Valle inferior del río Chubut (VIRCH, en la provincia homónima; las cuales cumplen con los requisitos para lograr buenas producciones del cultivo. El principal destino de esta fruta es además del consumo interno, la exportación a EEUU y la Unión Europea (UE, representando un saldo comercial importante para las zonas productoras.

    Full Text Available Pterosaur remains from the Río Belgrano Formation, Santa Cruz Province, Argentina, were found close to the Estancia Río Roble, along with several ammonoids that indicate a Barremian age for those strata. The specimens (MACN-SC 3617 consist of one ulna and one element tentatively identified as a portion of a wing metacarpal. The ulna shows morphological affinities with the Pteranodontoidea (sensu Kellner 1996, particularly with the members of the Anhangueridae by having a well developed ventral crest close to the proximal articulation, and is tentatively referred to this pterosaur clade. The oldest record of the Anhangueridae, previously limited to the Aptian/Albian, is therefore extended to the Barremian. The Argentinean material is preserved in three dimensions, an unusual condition for pterosaur fossils from that country, indicating that the site situated near the Estancia Río Roble has a great potential for new and well preserved specimens.

  19. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Argentina

    International Nuclear Information System (INIS)

    1977-08-01

    Argentina is a predominantly lowland area of 2,789,240 square kilometers. The capital is Buenos Aires. The entire length of Argentina is bordered on the west by the Andes Mountains. Tile Northwest Andes-Piedmont region consists of deep valleys containing salt basins and volcanoes, and is an earthquake zone. Patagonia, in the south, is essentially an arid region of windy plateaus and valleys. The southern Andes are narrower and lower than the northern Andes and in the extreme south contain glaciers and ice fields. The east-central plain (Pampa) of Argentina has dry and humid sectors and contains most of the population. The largest rivers are chiefly in the northeast, many having only seasonal flow. There has been extensive surface and subsurface exploration for uranium in Argentina for over 20 years. Although most of the work has been performed by the CNEA, advisors from the U.S. and from the IAEA have also taken part. Private industry has been involved, but apparently only on a small scale. In the OECD report of 1970, it was stated that 400,000 square kilometers of Argentina appear very favorable for uranium while an additional 900,000 square kilometers offer fair possibilities. Uranium exploration to date suggests that sandstones of Permian and Cretaceous ages exposed in Western Argentina in the Cordillera are very promising for discovery of new deposits. Past CNEA estimates have indicated that there is considerable hope for new discoveries in those areas where reserves are now known. In addition to the known uraniferous provinces which are indeed favorable for further exploration, there are several other large areas that warrant attention. There are, for example, in the Santa Cruz area of about 15,500 square kilometers Cretaceous and Tertiary sediments with favorable facies for uranium deposition. In the Patagonia Cordillera, Jurassic, Cretaceous, and Tertiary sediments are of interest for prospecting, These rocks contain carbonaceous material and have been

El grado de movilización social de los militantes católicos y liberales en las calles de Santa Fe y Rosario, así como la alta densidad de conflictos, acuerdos y rupturas entre los partidos y sus inestables facciones en el seno de la Constituyente hicieron de la coyuntura un potente matrizador de las identidades políticas. El artículo intenta paralelamente acercarse de manera aproximatoria a algunos de los modos en que la política filtró las identidades de los sectores populares y alimentó los imaginarios sociales críticos sobre la democracia liberal.

O fluxo turístico de origem argentina revelou-se um ingrediente importante dessa trajetória. Este artigo focaliza um aspecto pouco explorado, aparentemente, da participação argentina no turismo estadual: a relação entre a situação macroeconômica do país vizinho e a demanda turística por Santa Catarina lá originada. Começa-se abordando brevemente a problemática geral da macroeconomia do turismo. Depois, discorre-se sobre o crescimento desse setor em Santa Catarina, destacando a presença de argentinos. A terceira parte desenvolve uma análise baseada em tratamento estatístico de dados sobre demanda e receita geradas por esses turistas no estado, com exame das correlações envolvendo taxa de câmbio e taxa de crescimento do PIB da Argentina. Palavras-chave: turismo; Santa Catarina; turistas argentinos; economia argentina Abstract The State of Santa Catarina has witnessed a considerable development of its tourist sector in the last decades. The demand from Argentina has proved to be an important factor of that growth. This article deals with a feature of the presence of Argentinians in the state which seems to be scarcely studied: the relationship between the macroeconomic situation of Argentina and the tourist demand in Santa Catarina originated from that country. The first part of the article considers briefly the general issue of tourism macroeconomics. The second one looks upon tourism growth in Santa Catarina, stressing the presence of visitors from Argentine. The third section develops an analysis based on statistical treatment of data concerning demand and income generated by such tourists in Santa Catarina, involving correlations that consider aspects like exchange rate and the rate of GDP increase in Argentina.

    It is important to characterize the clinical and epidemiological pattern of the influenza A (H1N1) pdm09 virus and compare it with influenza A (H3N2) virus, as surveyed in just a few studies, in order to contribute to the implementation and strengthening of influenza control and prevention strategies. The aims in this study were to describe influenza clinical and epidemiological characteristics in hospitalized patients, caused by influenza A (H1N1)pdm09 and influenza A (H3N2) viruses during 2013, in Santa Fe, Argentina. A retrospective study was conducted over 2013 among hospitalized patients with laboratory-confirmed influenza diagnosis. In contrast to patients with influenza A (H3N2) (20.5%), a higher proportion of hospitalizations associated with influenza H1N1pdm were reported among adults aged 35-65 years (42.8%). Of all patients, 73.6% had an underlying medical condition. Hospitalized patients with H1N1pdm were subject to 2.6 (95%CI, 1.0-6.8) times higher risk of severity, than those hospitalized with influenza A (H3N2). This results demonstrate the impact in the post-pandemic era of H1N1pdm virus, with increased risk of severe disease, in relation to H3N2 virus, both viruses co-circulating during 2013. © 2017 Wiley Periodicals, Inc.

    Full Text Available El desarrollismo de la segunda posguerra -en sus diferentes vertientes- llevó a su máxima expresión el ideal moderno de instrumentalización de la naturaleza como vía del mejoramiento social. En Argentina (como en América Latina, se adoptarían una variedad de prescripciones surgidas, principalmente, de la Comisión Económica para América Latina (CEPAL, mientras la disciplina urbanística sufriría una transformación profunda de sus bases teóricas, produciéndose un pasaje del “Urbanismo” al “planeamiento”. Esto como correlato directo del pasaje de una concepción “jurisdiccional” del territorio de intervención, a otra concepción “regional”. A partir de ello, se expondrán dos propuestas de crecimiento urbano para la ciudad de Santa Fe, una asentada en el desarrollismo tecnocrático, que hizo énfasis en las infraestructuras como medio técnico de control de la naturaleza, y la otra, más híbrida y alternativa, que hizo foco en la especificidad geográfica y cultural santafesina.

    Full Text Available Salsola kali is considered extremely valuable as an energy crop worldwide because it adapts easily to environments with strong abiotic stresses (hydric, saline and alkaline and produces large amounts of biomass in drylands. This species is categorized as an important weed in Argentina. The aim of this work was to design an agro-ecological zoning model for tumbleweed in Argentina, employing a Geography Information System. Based on the bioclimatic requirements for the species and the climatic data for Argentina (1981–2010 period, an agro-climatic suitability map was drawn. This map was superimposed on the saline and alkaline soil maps delineated by the Food and Agriculture Organization for dry climates, generating the agro-ecological zoning on a scale of 1 : 500 000. This zoning revealed very suitable and suitable cultivation areas on halomorphic soils. The potential growing areas extend from N of the Salta province (approximately 22° S to the Santa Cruz province (50° S. The use of tumbleweed on halomorphic soils under semi-arid to arid conditions, for the dual purpose of forage use and source of lignocellulosic material for bioenergy, could improve agricultural productivity in these lands. Furthermore, it could also contribute to their environmental sustainability, since the species can be used to reclaim saline soils over the years. Based on international bibliography, the authors outlined an agro-ecological zoning model. This model may be applied to any part of the world, using the agro-ecological limits presented here.

Estas regiones han sido categorizadas por la World Wildlife Foundation (WWF como áreas "en peligro crítico/ amenazada", y se les asigna el nivel de máxima prioridad de conservación como consecuencia de la destrucción de hábitat, la sobreexplotación, la contaminación y la introducción de especies exóticas. El carpincho presenta una preferencia marcada por los ambientes con abundancia de cuerpos de agua donde la vegetación palustre le proporciona alimento y refugio. De esta forma, tanto los cuerpos de agua como la vegetación asociada es determinante para la prevalescencia de poblaciones de carpinchos en un ambiente determinado. Para la provincia de Santa Fe los registros no son muy abundantes, registrándose hasta la actualidad unos 33 puntos de colecta/observación, la gran mayoría ubicados en el centro y norte de la provincia. El objetivo de la presente contribución es presentar nuevos registros de presencia de Hydrochoerus hydrochaeris en la cuenca del río Carcarañá (sur de la provincia de Santa Fe, y su asociación con algunas variables climático-ambientales y evaluar la distribución de esta especie. Finalmente, se discute la posible expansión o migración de este especie hacia el oeste de esta provincia y de la provincia de Buenos Aires.

    Full Text Available Existe escasa información sobre la alimentación de las especies de anfibios activas durante la estación fría o las estrategias de utilización de reservas lipídicas como fuente de energía durante el periodo de bajas temperaturas. Por lo tanto, se analizaron las estrategias de obtención y acumulación energética durante la estación de bajas temperaturas en un anfibio que se reproduce principalmente en otoño-invierno, Hypsiboas pulchellus (Hp, y uno que lo hace en primavera-verano, Dendropsophus nanus (Dn. Para ello se analizó la alimentación de ambas especies y se utilizó el peso de los cuerpos grasos (CG como indicador del desarrollo de las reservas energéticas. Si bien se encontró una elevada similitud en la dieta entre las especies, esto no implicó la ausencia de diferencias en las estrategias de obtención energética entre ellas. El bajo índice de vacuidad gastrointestinal de Hp, acompañado de CG poco desarrollados, permite señalar que, para sostener la elevada demanda energética de la actividad reproductiva concentrada en el otoño-invierno, esta especie continúa alimentándose aún en temperaturas bajas. Por otro lado, el índice de vacuidad de Dn fue mayor al de Hp, mientras que sus CG se encontraron bien desarrollados, por lo que esta especie utilizaría en mayor medida sus reservas lipídicas como fuente de energía para transitar el período de bajas temperaturas y llegar en buenas condiciones a la temporada reproductiva en la próxima primavera-verano.In environments with thermal and pluvial seasonality such as those of the Middle Paraná River floodplain (Province of Santa Fe, Argentina, most amphibian species reproduce during the warm season and drastically diminish their activity during winter.

    Activity of B-esterases (BChE: butyrylcholinesterase and CbE: carboxylesterase using two model substrates: α-naphthyl acetate and 4-nitrophenyl valerate) in a native frog, Leptodactylus chaquensis from rice fields (RF1: methamidophos and RF2: cypermethrin and endosulfan sprayed by aircraft) and non-contaminated area (pristine forest) was measured. The ability of pyridine-2-aldoxime methochloride (2-PAM) to reactivate BChE levels was also explored. In addition, changes in blood cell morphology and parasite infection were determined. Mean values of plasma BChE activities were lower in samples from the two rice fields than in those from the reference site. CbE (4-nitrophenyl valerate) levels varied in the three sites studied, being highest in RF1. Frog plasma from RF1 showed positive reactivation of BChE activity after incubation with 2-PAM. Blood parameters of frogs from RF2 revealed morphological alterations (anisochromasia and immature erythrocytes frequency). Moreover, a major infection of protozoan Trypanosoma sp. in individuals from the two rice fields was detected. We suggest that integrated use of several biomarkers (BChE and CBEs, chemical reactivation of plasma with 2-PAM, and blood cell parameters) may be a promising procedure for use in biomonitoring programmes to diagnose pesticide exposure of wild populations of this frog and other native anuran species in Argentina.

    Full Text Available El proceso de institucionalización de la policía santafesina, en Argentina, tuvo lugar en la segunda mitad del siglo XIX e implicó tensiones de distinta índole ya que ésta policía fue un factor clave en la resolución de los problemas comprendidos en la nueva agenda social. Este artículo analiza tres documentos administrativos de la policía que reportan casos de inconducta, amotinamiento y ebriedad protagonizados por agentes, cabos, sargentos y un primer oficial. Estas fuentes permiten indagar en los actos de la tropa y, por tanto, hacer visibles las tensiones entre sus prácticas y el comportamiento que las autoridades consideraban deseable. También, plantean preguntas importantes acerca de las motivaciones y representaciones que estas acciones implicaron. Nuestro marco teórico es la historia social, que pone de relieve a las relaciones sociales específicas y nos permite centrarnos en las luchas concretas de sentido. Utilizamos el concepto transgresión, que propone una mirada alternativa sobre qué acciones pueden considerarse contenciosas o contrarias al orden social, en función de su visibilidad y efectos disruptivos. Nuestro objetivo es contribuir al conocimiento de la institucionalización de un orden social moderno en Santa Fe, mediante el análisis de cómo la policía en formación afrontó transgresiones concretas hechas por integrantes de la tropa.

    The present study focuses on the evaluation of metal (chromium, copper, and lead), arsenic, and pesticide (atrazine and endosulfan) contamination in freshwater streams of one of the most important agricultural and industrial areas of central-eastern Argentina, which has not been reported earlier. The environmental fate of inorganic microcontaminants and pesticides was assessed. Samples were collected monthly for a year. Pesticide concentrations were measured in water; metal and arsenic concentrations were measured in water and sediments, and physicochemical variables were analyzed. In most cases, metals and arsenic in water exceeded the established guideline levels for the protection of aquatic biota: 98 and 56.25% of the samples showed higher levels of Cr and Pb, while 81.25 and 85% of the samples presented higher values for Cu and As, respectively. Cr, Pb, Cu, and As exceeded 181.5 times, 41.6 times, 57.5 times, and 12.9 times, respectively, the guideline level values. In sediment samples, permitted levels were also surpassed by 40% for Pb, 15% for As, 4% for Cu, and 2% for Cr. Geoaccumulation Index (Igeo) demonstrated that most of the sediment samples were highly polluted by Cr and Cu and very seriously polluted by Pb, which indicates progressive deterioration of the sediment quality. Atrazine never exceeded them, but 27% of the 48 water samples contained total endosulfan that surpassed the guidelines. The findings of this study suggest risk to the freshwater biota over prolong periods and possible risk to humans if such type of contaminated water is employed for recreation or human use. Improper disposal of industrial effluents and agricultural runoffs need to be controlled, and proper treatment should be done before disposal to avoid further deterioration of the aquifers of this area.

    The Santa Rosita Formation is one the most widely distributed lower Paleozoic units of northwest Argentina. At the Quebrada del Salto Alto section, east of Purmamarca, Jujuy Province, it is represented by four sedimentary facies: thick‐bedded planar cross‐stratified quartzose sandstones (A), thin‐bedded planar cross‐stratified quartzose sandstones and mudstones (B), wave‐rippled sandstones and bioturbated mudstones (C), and black and greenish gray shales (D). Paleocurrent data, sandstone architecture, and sedimentary structures from faciès A and B indicate bipolar/bimodal paleoflows, suggesting the action of tidal currents. The succession is interpreted as that of a tide‐dominated shelf, with only secondary influence of wave processes. Trace fossils are restricted to facies B and C.The Cruziana ichnocoenosis is preserved on the soles of thin‐bedded planar cross‐stratified quartzose sandstones (faciès B). This ichnocoenosis consists of Conostichus isp., Cruziana omanica, C. semiplicata, C. cf. tortworthi, Cruziana isp. Helminthopsis abeli, Monomorphichnus bilinearis, M. multilineatus, Palaeophycus tubularis, Rusophycus carbonarias, R. latus, and R. isp. The occurrence of Cruziana semiplicata, C. omanica, C. cf. tortworthi, and Rusophycus latus supports a Late Cambrian‐Tremadoc age. Slabbing of Cruziana shows complex interactions between biologic and sedimentologic processes, and suggests a predominance of exhumed traces, washed out and recast by tractive sand deposition. Sandstone soles are densely packed with biogenic structures and exhibit distinctive clusters of Rusophycus isp. that most likely represent trilobite nesting burrows. The Cruziana ichnocoenosis records the resident fauna of a protected, lower intertidal to subtidal interbar setting.The Skolithos ichnocoenosis is represented by high to low density vertical burrows of Skolithos linearis, which extend downwards to the quartzose sandstone soles of faciès B and

    The Southern part of Argentina is composed of five Provinces; Tierra del Fuego, Santa Cruz, Chubut, Rio Negro and Neuquen. A search for potential impact sites was performed by the author through the examination of 76 color LANDSAT satellite images ( 1:250,000 - resolution = 250 meters ) at the Instituto Geografico Militar ( IGM ) of Buenos Aires city. When a potential candidate was found a more detailed study of the site was done. If available the radar X-SAR satellite images of the Deutsche Forschungsanstalt fur Luft-und Raumfahrt, (DLR), Berlin, Germany , were also examined. The final step was to perform a review of the available published geologic information of each site at the Servicio Geologico y Minero Argentino ( SEGEMAR ), ( =Geological Survey of Argentina ), in Buenos Aires. The resulting catalogue contains information about sites where possible simple crater or complex impact structures could be present. Each case demands future detailed and `in situ' research by an impact cratering specialist. --Tierra del Fuego: TF1 ) Ushuaia 5569-II, No 218. Cerro Taarsh, Estancia San Justo.

    Full Text Available This study analyses morphology and morphometric growth changes of Halicarcinus planatus females until their terminal moult, and characterises new juvenile stages. Monthly samples were collected in the estuary of the Deseado River, Santa Cruz Province, Argentina. Crabs were sampled between the mid-intertidal and upper subtidal levels. Intermoult stages were analysed in sub-samples of adolescents and adults, and the presence of epizoic organisms was registered. Juveniles and adults were reared at the laboratory and examined for moult changes. All 3376 crabs caught were females, indicating a clear spatial segregation between sexes. Five juvenile stages (immature 1, 2, 3, 4 and adolescent and a mature one were recognised on the basis of morphology and morphometry. All immature stages differed in cephalothorax width (CW and abdomen width (AW. Positive allometry was observed in some juvenile stages and isometry in an immature stage and in mature females. Adolescents and adults encompassed a wide range of sizes, and the considerable size overlap between them suggests an anomalous growth process. Moult staging analysis indicated that adolescents have a high incidence of pre-moult stages in winter, when the terminal moult occurs. The measurements performed in laboratory-reared females indicated no abnormal increases during the moult. The terminal moult occurs within a wide size range, perhaps in association with mating.

    Full Text Available Calcareous nannofossils from two boreholes (Campo Bola and Sur Río Chico in the subsurface of eastern Austral Basin, Santa Cruz Province, Argentina, allowed the identification of Early to Middle Paleocene, Early to Middle Eocene and Late Eocene to Early Oligocene assemblages. These assemblages match the formations logged in the boreholes Campo Bola, Man Aike and Río Leona respectively, and represent three paleogene sedimentary cycles within the basin. These results permitted the reinterpretation of previous data from an adjacent borehole (Cerro Redondo. The southern boreholes (Cerro Redondo and Sur Río Chico yield an Early to Middle Paleocene calcareous nannofossil assemblage and an almost continuous record of nannofossils from Early Eocene to Early Oligocene. A discontinuity is interpreted by the absence of Late Paleocene assemblages. The northern borehole (Campo Bola yield only late Early Eocene to Early Oligocene assemblages. The data also indicates that the Paleogene beds unconformably overlie Upper Cretaceous strata.El estudio de los nanofósiles calcáreos recuperados en muestras de subsuelo de dos pozos de exploración (Campo Bola y Sur Río Chico en el este de la Cuenca Austral, provincia de Santa Cruz, Argentina, permitió reconocer asociaciones del Paleoceno Temprano a Medio, Eoceno Temprano a Medio y Eoceno Tardío a Oligoceno Temprano. Estas asociaciones son coincidentes con las formaciones atravesadas en los sondeos hechos en Campo Bola, Man Aike y Río Leona, respectivamente, y representan tres ciclos sedimentarios paleógenos dentro de la cuenca.

Metodología: se realizaron tres estudios epidemiológicos con diseño ecológico que utilizan datos censales y estadísticas vitales como fuentes secundarias. Resultados: los hallazgos confirmaron un fuerte gradiente desfavorable en la mortalidad infantil para quienes se hallan en desventajas sociales. La gravedad de las disparidades observadas en la mortalidad infantil se hace más aguda cuando se aborda la mortalidad posneonatal.

    Despite the abundant fossil content of the Mata Amarilla Formation (Southern Patagonia, Santa Cruz Province, Argentina), its age has always generated a considerable number of questions and debates. The chronological data provided by invertebrates, dinosaurs, fish, turtles, plesiosaurs and fossil flora are contradictory. In this work, twenty U-Pb spot analyses by laser ablation were carried out on the outer parts of the zoned zircon crystals from a tuff layer of the middle section of the Mata Amarilla Formation, yielding a U-Pb concordia age of 96.23±0.71 Ma, which corresponds to the middle Cenomanian. The deposition of the lower section of the Mata Amarilla Formation marks the onset of the foreland stage of the Austral Basin (also known as Magallanes Basin); this transition is characterized by the west-east shift of the depositional systems, which is consistent with the progradation of the Cretaceous fold-and-thrust belt. Thus, the onset of the foreland stage could have occurred between the upper Albian and lower Cenomanian, as the underlying Piedra Clavada Formation is lower Albian in age. On comparing the data obtained with information from the Ultima Esperanza Province in Chile, it can be suggested that the initiation of the closure of the Rocas Verdes Marginal Basin occurred simultaneously

Un reducido número de agricultores, inquietos por generar actividades que diversificaran el tradicional modelo pastoril, experimentaron los dilemas de los comienzos y las crisis de un proyecto de estímulo económico en un territorio marginal. Este trabajo contribuye con una serie de reflexiones acerca de las motivaciones que justifican el estudio de pequeñas sociedades en áreas marginales; de la confrontación entre el marco conceptual de la marginalidad según los países centrales y los periféricos; y del accionar y el compromiso de los actores sociales motivados por una alternativa de desarrollo local en una localidad ubicada en el centro de la Patagonia Meridional Argentina.

    2012-01-01

    Federal welfare reform, local service collaborations, and the evolution of statewide information systems inspired agency interest in evidence-informed practice and knowledge sharing systems. Four agency leaders, including the Director, Deputy Director, Director of Planning and Evaluation, and Staff Development Program Manager championed the development of a learning organization based on knowledge management throughout the agency. Internal department restructuring helped to strengthen the Planning and Evaluation, Staff Development, and Personnel units, which have become central to supporting knowledge sharing activities. The Four Pillars of Knowledge framework was designed to capture agency directions in relationship to future knowledge management goals. Featuring People, Practice, Technology and Budget, the framework links the agency's services, mission and goals to the process of becoming a learning organization. Built through an iterative process, the framework was created by observing existing activities in each department rather than being designed from the top down. Knowledge management can help the department to fulfill its mission despite reduced resources. Copyright © Taylor & Francis Group, LLC

    Full Text Available This is a case study of the financial situation of an enterprise in the food sector which has cash flow difficulties resulting from its fast growth and from hastening decisions, such as the acquisition of a competitor, which generated new levels of production and commercialization and consequently the need for more working capital. Faced with the urgency to obtain resources to overcome the immediate cash difficulties, alternatives are presented for evaluation by students in order to choose the best option. The learning emphasis is on the calculation of the effective cost of capital for different proposals of raising resources and their consequences for the enterprise’s cash flow during the period analyzed. The case can be used in undergraduate and graduate programs, in courses aiming to stimulate discussions about the decision-making process of financial alternatives.

    The practice of neurosurgery in Bolivia began thousands of years ago with skull trepanation. This procedure dates from the earliest period of the Tiwanaku culture, a preInca civilization. Neurosurgical development in Bolivia has its origins in the late 19(th) century and can be divided in two stages. At the beginning, before the advent of neurosurgery as a discipline, some general surgeons performed procedures on the skull and brain. Formal neurosurgery in Bolivia was developed with the arrival of neurosurgeons trained in the United States and some countries of South America. The Bolivian Neurosurgical Society was created in 1975. Nowadays, our national society has 74 members. It is affiliated with the World Federation of Neurosurgical Societies and the Latin American Federation of Neurosurgical Societies. Presently, neurosurgery in Bolivia is similar to that seen in developed countries. In this sense, government programs should dedicate more financial support to establish specialized healthcare centers where the management of complex central nervous system lesions could be offered. In contrast, we believe that encouraging the local training of young neurosurgeons is one of the most important factors in the development of neurosurgery in Bolivia or any other country.

    Increasing population, agricultural development (including shifts to more water-intensive crops), and climate variability are placing increasingly larger demands on available groundwater resources in the Pajaro Valley, one of the most productive agricultural regions in the world. This study provided a refined conceptual model, geohydrologic framework, and integrated hydrologic model of the Pajaro Valley. The goal of this study was to produce a model capable of being accurate at scales relevant to water management decisions that are being considered in the revision and updates to the Basin Management Plan (BMP). The Pajaro Valley Hydrologic Model (PVHM) was designed to reproduce the most important natural and human components of the hydrologic system and related climatic factors, permitting an accurate assessment of groundwater conditions and processes that can inform the new BMP and help to improve planning for long-term sustainability of water resources. Model development included a revision of the conceptual model of the flow system, reevaluation of the previous model transformed into MODFLOW, implementation of the new geohydrologic model and conceptual model, and calibration of the transient hydrologic model.

    2011-01-01

    Studies of Malacothamnus fasciculatus var. nesioticus were begun in 1995 to understand its distribution, reproductive biology and ecological requirements. After 100+ years of depredation by sheep, two known populations of fewer than 20 plants each survived in 1995. Molecular studies showed that each of the two populations was composed of 1–3 genets. During our study, two additional populations of similar size were discovered. Plants are self-compatible but require insect visitation to augment pollination. Based on seed set, viable embryos, and germination rates, we found no evidence for inbreeding depression. Bush mallow also reproduces vegetatively by rhizomes, the primary means of establishment and persistence in natural populations, and a key feature for maximizing recovery success. Ex situ observations and trial in situ outplantings suggested that supplemental watering was critical to initial survival. We developed a recovery strategy composed of four plots located at varying elevations and aspects. Each plot was enclosed to exclude feral pigs, which posed a continuing threat. Each plot was planted with twelve rooted plants derived from each of three natural populations. Plants were provided supplemental watering for four months. Survivorship after one year ranged from 46% to 91%. Significant differences in survivorship were observed relative to source of plants. After twelve months some plants were flowering and reproducing vegetatively.

    Full Text Available Despite the abundant fossil content of the Mata Amarilla Formation (Southern Patagonia, Santa Cruz Province, Argentina, its age has always generated a considerable number of questions and debates. The chronological data provided by invertebrates, dinosaurs, fish, turtles, plesiosaurs and fossil flora are contradictory. In this work, twenty U-Pb spot analyses by laser ablation were carried out on the outer parts of the zoned zircon crystals from a tuff layer of the middle section of the Mata Amarilla Formation, yielding a U-Pb concordia age of 96.23±0.71 Ma, which corresponds to the middle Cenomanian. The deposition of the lower section of the Mata Amarilla Formation marks the onset of the foreland stage of the Austral Basin (also known as Magallanes Basin; this transition is characterized by the west-east shift of the depositional systems, which is consistent with the progradation of the Cretaceous fold-and-thrust belt. Thus, the onset of the foreland stage could have occurred between the upper Albian and lower Cenomanian, as the underlying Piedra Clavada Formation is lower Albian in age. On comparing the data obtained with information from the Última Esperanza Province in Chile, it can be suggested that the initiation of the closure of the Rocas Verdes Marginal Basin occurred simultaneously.A pesar del abundante contenido fosilífero de la Formación Mata Amarilla (Patagonia Austral, Provincia de Santa Cruz, Argentina, siempre se generaron abundantes dudas y debates acerca de cuál es la edad de esta formación.

Using this evidence as point of departure, this sermon is used as an example of shifting currents of opinion in female convents related to the Querelle des Femmes, currents of opinion that interacted with the main social and cultural debates of the period. These debates were closely related to the socalled “genealogical turn” which Iberian societies underwent in the 15th century.Este trabajo se articula en torno al sermón de Santa Ana de El Conhorte de Juana de la Cruz. Su temática incide en imágenes de vida y generación y defiende el peso de las genealogías maternas.

The accurate and well diffused net of the Fogolār Furlan, besides its function as friendly society, also provides to the promulgation of ancient traditions and mores among the new generations, transmitting on to them the cultural, linguistic and ethnic memory of the motherland. Epistles, tales, novels and poems form a paideia which is thus constantly being enlivened, eveng among those who assumed Argentinian nationality or were born in the country. Of utmost interest is, therefore, the resulting literary corpus, representing as it does a renewed search for identity in the form of a dialogue with the world, extending itself well beyond the contingency of boundaries and transmitting the universal essence of logos.

    The article deals with Argentina's nuclear power programme over the last 30 years, including the country's efforts to be nuclear independent of the United States, as well as its aspirations to be a nuclear supplier to latin America. The latter policy on economic, rather than military grounds for nuclear weapons, has led to Argentina's decision to build a uranian enrichment plant. (U.K.)

  14. Biogenic and pedogenic controls on Si distributions and cycling in grasslands of the Santa Cruz soil chronosequence, California

    Biogenic and pedogenic processes control silica cycling in grasslands growing on a soil chronosequence and dominated by strong seasonal variabilities of a Mediterranean climate. Shallow pore water Si, in spite of significant annual uptake and release by plant growth and dieback, exhibits only moderate seasonal fluctuations reflecting strong buffering from labile biogenic Si, dominated by phytoliths and by secondary pedogenic silicates. Long phytolith residence times (340-900 yrs) reflect the seasonally dry climate and high solute Si concentrations. Water-extractable Si is closely associated with Al, indicating seasonal precipitation and dissolution of a highly labile 1:1 hydroxyaluminosilicate (HAS), probably allophane, which transforms in deeper soil into fine grained, poorly crystalline kaolinite. Shallow plant roots extract greater proportions of biogenic Si and deeper plant roots larger amounts pedogenic Si. High pore water Ge/Si in late winter and spring reflects the reinforcing effects of plant fractionation and concurrent dissolution of Ge-enriched HAS. The same processes produce pore waters with depleted 30Si/28Si. In the summer and fall, Ge/Si declines and 30Si/28Si increases, reflecting the cessation of plant uptake, continued dissolution of soil phytoliths and re-precipitation of less soluble HAS. Si inputs from weathering (2-90 mmol m-2 yr-1) and losses from pore water discharge (18-68 mM m-2 yr-1) are comparable for individual soils, decline with soil age and are significantly less than amounts of Si annual cycled through the vegetation (42-171 mM m-2 yr-1). Mobile Si is generally balanced in the soils with upward bio-pumping by the shallow-rooted grasses efficiently competing against downward leaching and pore water discharge. Small net annual increases in Si in the present day soils could not have been maintained over the time scale represented by the chronosequence (65-225 yrs), implying past changes in environmental conditions.

  15. Construcción de silos con encofrados deslizantes - Santa Cruz de Tenerife – España

    Barrios Martínez, M.

    1976-10-01

    Full Text Available These cereal and oil-cake silos are made up of 10 exterior cylindrical cells, with an inner diameter of 6 m and a height of 31.88 m. The cells are joined together by means of walls whereby four additional octagonal cells are created. Out of these, three are subdivided into four cells and the fourth forms the central silo. Below this unit there is a corridor for the emptying of the silos. The work has been carried out with a travelling form with the following characteristics: mixed with regard to shape and materials; stiff, since the top platforms are connected; and it has a constant cross-section as the dimensions of the silos remain the same throughout the whole height. The form was lifted by means of elevation devices, controlled by a centralized hydraulic mechanism. In view of the characteristics of the travelling form, the concrete used ¡n the work had to fulfill several very special conditions, notably different from these applying to the concrete that is normally used for fixed forms. For this reason, it was submitted to a great number of studies and tests until the requirements had been met. The construction was finished in record time: in the first place, because a detailed programme had been worked out in advance, consisting of a diagram of bars and preference network and secondly, because continuous concreting was applied with day and night shifts, whebery the foreseen two and a half months for finishing the silos were reduced to 12 days.Estos silos, destinados a almacenamiento de cereales y borujo, están formados por 10 celdas exteriores cilíndricas, de 6 m de diámetro interior y 31,88 m de altura, que se unen entre sí por medio de muros, dando lugar a cuatro celdas adicionales de forma octogonal. De éstas, tres están subdivididas en cuatro interceldas, quedando la cuarta como silo central. Debajo del conjunto se ha dispuesto una galería para el vaciado de los silos. La obra se ha realizado con un encofrado deslizante que reúne las siguientes características: es mixto, en cuanto a la forma y materiales; rígido, por el enlace de las plataformas superiores de trabajo; y de sección constante, por mantener los silos las mismas dimensiones en toda su altura. La maniobra de ascenso del encofrado se conseguía mediante dispositivos de elevación accionados por mando hidráulico centralizado. Dadas las particularidades del encofrado deslizante, el hormigón utilizado en la obra debía reunir una serie de condiciones especiales, sensiblemente distintas a las del hormigón que normalmente se emplea con encofrados fijos, por lo que fue objeto de numerosos estudios y ensayos hasta conseguir su perfecta adecuación. La construcción se llevó a cabo en un tiempo récord: en primer lugar, por la confección previa de un detallado programa que consiste en un gráfico de barras y una red de precedencias; y, en segundo lugar, por la implantación de un hormigonado continuo, con tumos de día y de noche, con lo que se consiguió disminuir en doce días los dos meses y medio previstos para la terminación.

    Norman, Laura M.; Feller, Mark; Villarreal, Miguel L.

    2012-01-01

    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.

    Full Text Available Eating habits in adolescence, may suffer several changes as they can vary from one day to another. The objective of this study is to determine the eating habits of adolescents aged 10 to 15 years old. The study comprised 81 students aged between 10 and 15 years, 48 male and 33 female students, from Gaspar Bartholomay Elementary School. The research was carried out through a descriptive exploratory study, addressing the eating habits and weight control, and focusing on the frequency of food consumption per week. The tool for the study was a questionnaire on health and well-being - children and adolescents - eating habits and weight control. According to the results obtained in this study, the consumption of fried foods, pizza, lasagna and treats,were consumed less frequently, being considered among adolescents as a good eating habit, since foods such as these will cause obesity if consumed more frequently and in large quantities. In relation to the consumption of salads and vegetables males (40.5% have the habit of eating more that kind of food, when compared to the females(38.2%. For both genders, adults become more or less prone to obesitywith a more regular consumption of this type of food. Thus, we can see that the teenagers in their diet, prioritize foods they like to eat, and seldom choose foods which are healthier, without worrying about becoming obese adolescents or even in the future, obese adults with poor eating habits.

    2015-06-01

    The aim of this research study was to describe the perceived level of food security in the households of the city of Santa Fe, Argentina, in 2011. A descriptive, cross-sectional study was performed, incorporating 592 homes included in the Panel of Households of the Social Observatory of the Universidad Nacional del Litoral. Households were characterized sociodemographically and classified according to the level of food security by applying the Latin American and Caribbean Food Security Scale. Association with sociodemographical factors was determined by odds ratios and logistic regression. It was found that 31.5% of households in Santa Fe show food insecurity: 21.7% is mild, 7.4% is moderate and 2.4% is severe, and insecurity is greater when children live in the household. Food insecurity is positively associated with lack of health coverage, lack of economic activity, inability to save, incomplete secondary level education and four or more people living in the household.

    Laguna Potrok Aike, a maar lake in southern-most Patagonia, is located at about 110 m a.s.l. in the Pliocene to late Quaternary Pali Aike Volcanic Field (Santa Cruz, southern Patagonia, Argentina) at about 52°S and 70°W, some 20 km north of the Strait of Magellan and approximately 90 km west of the city of Rio Gallegos. The lake is almost circular and bowl-shaped with a 100 m deep, flat plain in its central part and an approximate diameter of 3.5 km. Steep slopes separate the central plain from the lake shoulder at about 35 m water depth. At present, strong winds permanently mix the entire water column. The closed lake basin contains a sub saline water body and has only episodic inflows with the most important episodic tributary situated on the western shore. Discharge is restricted to major snowmelt events. Laguna Potrok Aike is presently located at the boundary between the Southern Hemispheric Westerlies and the Antarctic Polar Front. The sedimentary regime is thus influenced by climatic and hydrologic conditions related to the Antarctic Circumpolar Current, the Southern Hemispheric Westerlies and sporadic outbreaks of Antarctic polar air masses. Previous studies demonstrated that closed lakes in southern South America are sensitive to variations in the evaporation/precipitation ratio and have experienced drastic lake level changes in the past causing for example the desiccation of the 75 m deep Lago Cardiel during the Late Glacial. Multiproxy environmental reconstruction of the last 16 ka documents that Laguna Potrok Aike is highly sensitive to climate change. Based on an Ar/Ar age determination, the phreatomagmatic tephra that is assumed to relate to the Potrok Aike maar eruption was formed around 770 ka. Thus Laguna Potrok Aike sediments contain almost 0.8 million years of climate history spanning several past glacial-interglacial cycles making it a unique archive for non-tropical and non-polar regions of the Southern Hemisphere. In particular, variations of

No entanto, o uso e a comercialização de sementes de azevém tetraploide têm crescido em relação aos diploides, devido, principalmente, a qualidade superior de suas sementes. O objetivo do trabalho foi avaliar a qualidade das sementes de azevém tetraploide, comercializadas no Estado de Santa Catarina. Foram utilizados seis lotes de sementes de azevém tetraploide da cultivar Barjumbo, oriundos de diferentes estabelecimentos comerciais do Estado de Santa Catarina. Cada lote de semente foi obtido a partir de coleta oficial. Buscaram-se lotes de sementes da categoria certificada, sendo dois lotes de cada país produtor (Argentina, Brasil e Uruguai. Avaliou-se a qualidade física e fisiológica a partir dos testes de pureza física, massa de mil sementes, teste de germinação, primeira contagem de germinação, comprimento da parte aérea e da raiz e massa seca da área e da raiz. Os resultados demonstram que 100% dos lotes analisados atendem os padrões legais de pureza física e germinação para a comercialização de sementes, independente da origem.

    This report serves as the Final Report for Santa Barbara County’s Energy Efficiency and Conservation Block Grant (EECBG) BetterBuildings Neighborhood Program (BBNP) award from the U.S. Department of Energy (DOE). This report explains how DOE BBNP funding was invested to develop robust program infrastructure designed to help property owners complete energy improvements, thereby generating substantial outcomes for the local environment and economy. It provides an overview of program development and design within the grant period, program accomplishments and challenges to date, and a plan for the future sustainability of emPower, the County’s innovative clean energy and building efficiency program. During the grant period, Santa Barbara County’s emPower program primarily targeted 32,000 owner occupied, single family, detached residential homes over 25 years old within the County. In order to help these homeowners and their contractors overcome market barriers to completing residential energy improvements, the program developed and promoted six voluntary, market-based service areas: 1) low cost residential financing (loan loss reserve with two local credit unions), 2) residential rebates, 3) local customer service, 4) expert energy advising, 5) workforce development and training, and 6) marketing, education and outreach. The main goals of the program were to lower building energy use, create jobs and develop a lasting regional building performance market. These services have generated important early outcomes and lessons after the program’s first two years in service. The DOE BBNP funding was extended through October 2014 to enable Santa Barbara County to generate continued outcomes. In fact, funding related to residential financing remains wholly available for the foreseeable future to continue offering Home Upgrade Loans to approximately 1,300 homeowners. The County’s investment of DOE BBNP funding was used to build a lasting, effective, and innovative

    Buyers are lining up for Argentina's two big state-controlled petrochemical groups, Buenos Aires-based Petroquimica General Mosconi (PGM) and Petroquimica Bahia Blance (PBB). However, feedstock supply contracts with government-owned oil group Yacientos Petroliferos Fiscales (YPG) and gas group Gas del Estado hold the key to both sales. Shell Compania Argentina Petroleo SA (CAPSA), Perez Companc, and Global Petroleum have already bought PGM tender documentation. Shell says it will bid for PGM if the feedstock contract with YPF is acceptable. In addition to price and volume, Shell says the length is critical; it wants a 15-year deal, but would settle for 11. YPF initially sought a five-year contract. PGM, which produces 300,000 m.t./year of aromatics, plus oxo alcohols, methanol, and methyl tert-butyl ether, has sales of $150 million/year

    The airborne geophysical surveys developed in Argentina are described. They have got more than 500.000 km 2 acquiring data for U, Th, K and total background activity. Other types of published data are also mentioned (satellite imagery, seismic hazard, climate, soil distributions, etc.). The availability of maps with the abundances of elements analyzed at the country and also at laboratories from Canada is described, as well as data of analysis of several elements at two study areas proposed at the outset of the project. The availability of process rate data and epidemiological data is also explained. Argentina intended fully to participate in the CRP at the outset of the project. Due, however, to external resource constraints imposed on the participating organization (Comision Nacional de Energia Atomica, CNEA), the level of participation had to be significantly reduced. Nonetheless, in the first period of the CRP, Argentina undertook to collate existing geological and geochemical information within the country, and began to define potential areas for site specific natural systems safety indicator studies.

    Gravity anomalies, historical records of exploratory oil wells and oil seeps, new organic-geochemical results, and new stratigraphic and structural data indicate the presence of a concealed, oil-bearing sedimentary basin beneath a highly urbanized part of the Santa Clara Valley, Calif. A conspicuous isostatic-gravity low that extends about 35 km from Palo Alto southeastward to near Los Gatos reflects an asymmetric, northwest-trending sedimentary basin comprising low-density strata, principally of Miocene age, that rest on higher-density rocks of Mesozoic and Paleogene(?) age. Both gravity and well data show that the low-density rocks thin gradually to the northeast over a distance of about 10 km. The thickest (approx 4 km thick) accumulation of low-density material occurs along the basin's steep southwestern margin, which may be controlled by buried, northeast-dipping normal faults that were active during the Miocene. Movement along these hypothetical normal faults may been contemporaneous (approx 17–14 Ma) with sedimentation and local dacitic and basaltic volcanism, possibly in response to crustal extension related to passage of the northwestward-migrating Mendocino triple junction. During the Pliocene and Quaternary, the normal faults and Miocene strata were overridden by Mesozoic rocks, including the Franciscan Complex, along northeastward-vergent reverse and thrust faults of the Berrocal, Shannon, and Monte Vista Fault zones. Movement along these fault zones was accompanied by folding and tilting of strata as young as Quaternary and by uplift of the modern Santa Cruz Mountains; the fault zones remain seismically active. We attribute the Pliocene and Quaternary reverse and thrust faulting, folding, and uplift to compression caused by local San Andreas Fault tectonics and regional transpression along the Pacific-North American Plate boundary. Near the southwestern margin of the Santa Clara Valley, as many as 20 exploratory oil wells were drilled between 1891

Diferenças acentuadas no comportamento higiênico entre colônias de abelhas foram relatadas em Santa Catarina, Brasil. Suspeitou-se que essas diferenças fossem devidas a um possível fluxo gênico entre as abelhas africanizadas brasileiras e as abelhas europeias da Argentina. Amostras de abelhas de 30 localidades de Santa Catarina foram analisadas por meio do uso de um marcador PCR-RFLP do DNA mitocondrial específico para identificação da origem da linhagem maternal. Os resultados indicaram ausência de linhagem materna de origem europeia em Santa Catarina. Baseando-se em hipóteses e resultados de trabalhos anteriores, conclui-se que não há fluxo gênico entre as populações das diferentes subespécies. O resultado também reforça que a eliminação do DNA maternal europeu é um indicativo de ineficácia de introduções de abelhas de subespécies europeias, no Brasil, com propósitos de melhoramento do atributo agressividade.

    We studied patterns of genetic diversity within and among 5 populations (318 individuals) of Galápagos marine iguanas (Amblyrhynchus cristatus) from the island Santa Fé. Populations were separated by distances of 0.2 to 9.9 km. We sequenced 1182 base pairs of the mitochondrial control region and screened 13 microsatellite loci for variability. We also added data from 5 populations (397 individuals) sampled on 4 neighboring islands (Santa Cruz, Floreana, Espanola, and San Cristobal). The 5 Santa Fé populations, revealed as genetically distinct from populations on other islands, present relatively low levels of genetic diversity, which are similar for both microsatellite (average observed heterozygosity from 0.7686 to 0.7773) and mitochondrial DNA (mtDNA) markers (haplotypic and nucleotide diversity from 0.587 to 0.728 and from 0.00079 to 0.00293, respectively), and comparable with those observed in similar-sized sampling sites on other islands. There was frequency-based evidence of genetic structure between northern and southern sites on Santa Fé (F(st) of 0.0027-0.0115 for microsatellite and 0.0447-0.2391 for mtDNA), but the 4 southern sites showed little differentiation. Most of the intra-island genetic variation was allocated within rather than between sites. There was no evidence of sex-biased dispersal or population substructuring due to lek-mating behavior, suggesting that these 2 observed behaviors are not strong enough to leave an evolutionary signal on genetic patterns in this species.

    Full Text Available This work studies how the set of relationships that gives place to the learning processes is established in the food industry in Argentina. A theoretical ad hoc approach is adopted, conjugating the concepts of innovation systems at sector / regional level with some context considerations like the innovative behaviour of the global and local food industry and a description of the public and private S&T in Argentina. The study is focused in two cases: the wine industry, at the Mendoza province, and the dairy products industry at the centre of the Santa Fe province, both in Argentina. While the winery industry at the province of Mendoza exports differentiated products the dairy industry, at the central basin of the province of Santa Fe, exports commodities leaving differentiated (functional products for the domestic market. These facts determine different dynamics between them, despite of what the established set of relationships is very complex and knowledge intensive in both cases. Also, in both cases the preponderant contribution of the public institutions of science and technology as knowledge and technology source is flagged.

    The Atomic Energy Commission of Argentina has been an active participant of the RERTR program since 1978. An important milestone of the Argentinean RERTR program was the development and manufacturing at industrial scale of U 3 O 8 dispersed fuel and its subsequent application to the conversion of the RA-3 reactor core to LEU fuel. More recently, our activities were focused on the development of U 3 Si 2 fuel with a density of 4.8 gU/cm 3 and the improvement of the manufacturing process of this type of fuel. The program to qualify CNEA as a supplier U 3 Si 2 dispersed fuels is scheduled to finalize by mid 2003. To hasten this program the main research reactor of Argentina, the RA3, raised its power from 5 MW to 8 Mw in October this year. This is an intermediate step in the program to increase RA-3 power to 10 MW Currently, one of the main objectives is to develop and qualify the technology for the production of high-density LEU fuel elements using U-Mo alloy. An original way to produce U-Mo powder (the HMD process) was developed and its being upgraded to plant scale production. Another significant progress was the development of LEU targets for the production of 99 Mo, in the form of miniplates prepared with dispersed LEU U-Al x . The shipment to USA of 207 MTR spent fuels containing US origin highly enriched uranium, successfully carried out in the end of 2000, is another remarkable achievement of the Argentinean RERTR program. This activity was carried out in the framework of the United States Foreign Research Reactor Spent Nuclear Fuel Acceptance Program. The fuels were fabricated in Argentina and used in the RA-3 reactor from 1968 to 1987. The inventory of the shipped HEU spent fuel consisted in 166 standard assemblies and 41 control assemblies.

The operating factor of 91.52% obtained in 2003 is the Plant's best historical result in a year with a refueling outage. This factor is an indication of reasonable Plant operation throughout the year, and also of the results of the optimization and quality efforts made in preparing and executing the refueling outage. The collective dose indicator is also the best historical datum in year with a refueling outage and keeps our Plant in a relevant position among the world's BWR plants. The objective set by INPO is clearly achieved. The result is the outcome of the improvement studies and ALARA actions taken during job preparation and planning and also of equipment and installation improvements and modernization. The three differential follow-up objective of the NUCLENOR Corporate Project are: Strengthening of the Safety Culture, Operating License Renewal and Improved in-Plant Task Management

    In 1989, the US Department of Energy (DOE) responded to the need to redirect resources from weapons production to environmental restoration and waste management by establishing the Office of Environmental Management (EM) and delegated to this office the responsibility of cleaning up the US nuclear weapons complex. Now in its eight year, EM's mission has three central facets: (1) to assess, remediate, and monitor contaminated sites and facilities; (2) to store, treat, and dispose of waste from past and current operations; and (3) to develop and implement innovative technologies for environmental cleanup. To this end, EM has established domestic and international cooperative technology development programs, including one with the Republic of Argentina. Cooperating with Argentine scientific institutes and industries meets US cleanup objectives by: (1) identifying and accessing Argentine EM-related technologies, thereby leveraging investments and providing cost-savings; (2) improving access to technical information, scientific expertise, and technologies applicable to EM needs; and (3) fostering the development of innovative environmental technologies by increasing US private sector opportunities in Argentina in EM-related areas

    QUBIC (QU Bolometric Interferometer for Cosmology) is an experimental cosmology project to measure the modes in the polarization of the cosmic background radiation (CBR), the fossil relic that reveals the properties at the Universe 380,000 years after the Planck Era. Discovery of the CBR in 1964 and measurement of tiny temperature anisotropies in 1992 were major breakthroughs in our understanding of the Universe. The next challenge is to measure the polarization of the CBR accurately enough to detect modes that would reveal the existence of primordial gravitational waves produced in the first stages of the Planck Era and probe inflation theory, that assumes an accelerated expansion during the first seconds. The mode signal is however extremely weak and its measurement requires complex instruments. The QUBIC collaboration has developed the concept of interferometric bolometry, that brings together the sensitivity of bolometric detectors with the control of systematic effects provided by interferometry. QUBIC is an international collaboration involving several universities and laboratories in France, Italy, United Kingdom and USA. Recently, Argentina has suggested Alto Chorrillo (Salta), as candidate site for the installation of the experiment, next to the LLAMA site. Here we describe the scientific objectives and the main features of the experiment and we detail the process through which the international collaboration decided to install in Argentina its first module as well as the challenges for our country in this project.

    The Atomic Energy Commission of Argentina has been involved in the Reduced Enrichment for Research and Test Reactors Program since 1978. The most relevant milestones of the program, regarding fuel R and D activities, were the development and manufacturing at industrial scale of U 3 O 8 dispersed fuel assemblies and the conversion of the RA-3 reactor core to LEU fuel. More recently, the activities were focused in the development of high density U 3 Si 2 fuel with a density of 4.8 gU/cm 3 and the improvement of the manufacturing process of U 3 Si 2 powder. Currently one of the main objectives is to develop and qualify the technology for the production of high-density LEU fuel elements using U-Mo alloy. Several alternative ways to obtain U-Mo powder are under development with the aim of evaluating plant scale production and costs. To boost this program the main research reactor of Argentina, the RA-3, will be upgraded to 10 MW early in 2001 and the hot cells at the Ezeiza Atomic Center are fully operational after important investments. Significant progresses were also carried out in the development of LEU targets for the production of Mo 99 . Experimental work has demonstrated the feasibility of the manufacturing and radiochemical processing of miniplate targets prepared with dispersed UAl x , maintaining the geometry and the alkaline processing of the HEU targets used so far.

    Full Text Available We analyzed 391 samples from 12 Argentinian populations from the Center-West, East and North-West regions with the Illumina Human Exome Beadchip v1.0 (HumanExome-12v1-A. We did Principal Components analysis to infer patterns of populational divergence and migrations. We identified proportions and patterns of European, African and Native American ancestry and found a correlation between distance to Buenos Aires and proportion of Native American ancestry, where the highest proportion corresponds to the Northernmost populations, which is also the furthest from the Argentinian capital. Most of the European sources are from a South European origin, matching historical records, and we see two different Native American components, one that spreads all over Argentina and another specifically Andean. The highest percentages of African ancestry were in the Center West of Argentina, where the old trade routes took the slaves from Buenos Aires to Chile and Peru. Subcontinentaly, sources of this African component are represented by both West Africa and groups influenced by the Bantu expansion, the second slightly higher than the first, unlike North America and the Caribbean, where the main source is West Africa. This is reasonable, considering that a large proportion of the ships arriving at the Southern Hemisphere came from Mozambique, Loango and Angola.

A moeda do tempo e outros poemas, by Gastão Cruz, and some poems taken from Serial and Museu de tudo, by João Cabral, have been chosen. The comparative study of the literature of both poets provides us a comprehension of the importance of time and memory in their work. The ‘time’ studied in their poems is the time of mankind, the pulse of the existence in each verse, each word, each instant. The verses bring us pieces of life that wobble between past, present and future. The task of the reader is to experience the time and the ethics of these poets whose writing is committed to the aesthetic demand of poetry, without forgetting the soul.

    Argentine Nuclear Development started in early fifties. In 1957, it was decided to built the first a research reactor. RA-1 reactor (120 kw, today licensed to work at 40 kW) started operation in January 1958. Originally RA-1 was an Argonaut (American design) reactor. In early sixties, the RA-1 core was changed. Fuel rods (20% enrichment) was introduced instead the old Argonaut core design. For that reason, a critical facility named RA-0 was built. After that, the RA-3 project started, to build a multipurpose 5 MW nuclear reactor MTR pool type, to produce radioisotopes and research. For that reason and to define the characteristics of the RA-3 core, another critical facility was built, RA-2. Initially RA-3 was a 90 % enriched fuel reactor, and started operation in 1967. When Atucha I NPP project started, a German design Power Reactor, a small homogeneous reactor was donated by the German Government to Argentina (1969). This was RA-4 reactor (20% enrichment, 1W). In 1982, RA-6 pool reactor achieved criticality. This is a 500 kW reactor with 90% enriched MTR fuel elements. In 1990, RA-3 started to operate fueled by 20% enriched fuel. In 1997, the RA-8 (multipurpose critical facility located at Pilcaniyeu) started to operate. RA-3 reactor is the most important CNEA reactor for Argentine Research Reactors development. It is the first in a succession of Argentine MTR reactors built by CNEA (and INVAP SE ) in Argentina and other countries: RA-6 (500 kW, Bariloche-Argentina), RP-10 (10MW, Peru), NUR (500 kW, Algeria), MPR (22 MW, Egypt). The experience of Argentinian industry permits to compete with foreign developed countries as supplier of research reactors. Today, CNEA has six research reactors whose activities have a range from education and promotion of nuclear activity, to radioisotope production. For more than forty years, Argentine Research Reactors are working. The experience of Argentine is important, and argentine firms are able to compete in the design and

  14. History of radiobiology in Argentina

    International Nuclear Information System (INIS)

    Mayo, Jose

    2004-01-01

    Radiobiology is a multidisciplinary science dealing with ionising radiation effects on biological material. The history of Radiobiology begins in Germany and France around 1886. Radiobiology was introduced in Argentina in 1926 at the Institute of Oncology Angel H. Roffo as a biomedical research branch. Later on in 1957 was incorporated at the National Atomic Energy Commission (CNEA) of Argentina as a result of the newly started nuclear activities in Argentina. Prior that time no Radiobiology research existed in Argentina. To fill this need a Project to create new laboratories was elaborated by the CNEA. New laboratories in Radiobiodosimetry, Cellular Radiobiology, Radiopathology, Radiomicrobiology, Genetics and Somatic Effects were created. Human resources on different areas of Radiobiology were formed with the assistance of IAEA. With professional and technical personnel specialized in Radiobiology at the beginning of the 1970 decade, the transference of fundamental and applied research to others laboratories started.

    Full Text Available El presente trabajo se interroga en torno a las relaciones entre catolicismo y laicismo en el terreno educativo. Se pregunta, en particular, sobre la consistencia historiográfica de las imágenes construidas como reflejo de la tesis del "renacimiento católico". Según estos cuadros, la contracara del denominado "renacimiento" habría sido el ocaso de una "Argentina laica y liberal", consagrada en términos educativos en la ley 1420. Partiendo de estas visiones especulares, el texto se propone discutir, para el caso de la provincia de Santa Fe, algunos de los argumentos esgrimidos tras la "postal laicista", a la luz de los debates abiertos en torno a las teorías de la "secularización" y de la "modernidad".The present work studies the relationships between catholicism and laicism in the educational field. In particular, it wonders about the historiographic consistency of the images built as a reflection of the "catholic rebirth" thesis. According to these frames, the counterpart of the denominated "rebirth" would have been the decline of a "lay and liberal Argentina", established in educational terms in the 1420 law. Starting from these views, the text discusses, for the Santa Fe county case, some of the arguments fenced behind the "lay postal", in light of the opened debates around the theories of the "secularization" and of the "modernity".

    The oil and gas industry, which is especially significant in Argentina, is one industry that concentrates natural radionuclides during its processes. In addition, there are a few underground mines under development, where radon levels may be high. The Nuclear Regulatory Authority of Argentina (ARN) carried out a project with the objective of evaluating NORM, mainly in these types of industries. Eight facilities were characterized, three related to the gas industry, four related to the oil industry and a survey of radon gas in a gold underground mine. First, background measurements were made and then a screening survey was carried out to detect values above background. Of the values obtained, 57% were in the background range, 19% were below 2 μSv/h, 15% were in the range 2-10 μSv/h and 9% were above 10 μSv/h. Some values were as high as 400 μSv/h. The annual effective doses were estimated to be in the range 0.02-1.6 mSv/a. Samples were taken and later analysed by gamma spectrometry, liquid scintillation and fluorimetry. It was confirmed that the main radionuclides involved in the oil and gas extraction process are 226 Ra and 228 Ra. The radium isotope concentrations measured in some samples were above the exemption values established by the International Basic Safety Standards. Elevated radon levels were detected in gas facilities and in the gold mine under development. The values obtained in gas facilities showed that radon concentrates in the ethane and propane flows. As the flows in the gas industry are confined, it does not mean an exposure during normal operation. In the case of the gold mine, the values detected were informed to the pertinent authorities as well as the facility in order to take actions to reduce concentrations below the action levels. Finally, protective measures to reduce occupational doses in the cleaning and maintenance processes were suggested, as well as for storage of NORM-contaminated items. (author)

    The annual cycle, annual and seasonal frequency and geographical distribution of hail in Argentina during the 1960-2008 period are examined. Eight regions covering the whole territory were defined based on the correlation of the mean annual hail frequency between all weather stations. Regions lying between 30° and 40°S as well as those dominated by mountains present the highest hail frequencies in Argentina. The eastern and coastal areas of the country experience hail events mainly during springtime but they may start in late winter and continue through the beginning of summer. Events in western and central Argentina also predominate in spring but the maximum frequencies are observed during summer months. Trends in the annual number of hail events calculated for each region indicate that events in northwestern and northeastern Argentina have been increasing as well as in southern Patagonia. On the other hand, in central Argentina, southern Buenos Aires-La Pampa, northern Buenos Aires-Litoral and northern Patagonia trends are negative and statistically significant in the first two regions, basically by the decrease of events during spring and summer.

    Nuclear activities in Argentina are restarted. After almost two decades of near stagnation, the governments political decision of August 2006 regarding electrical energy production, considered the nuclear option as a valid one to solve the problems of the growing demand of electrical energy. This decision triggered again the activities related to the finalization of the third nuclear power reactor (Atucha-II), now actively progressing, the construction of a prototype of the CAREM integral advanced reactor, the life extension of the Embalse CANDU nuclear power plant (NPP) and the studies for the emplacement of a fourth NPP in an appropriate site. In all those years of near stagnation, there were notable exceptions related to the design and construction of experimental and radioisotope production reactors, led by INVAP, a state-owned industry, which exported its production. The accompanying industries of nuclear fuel elements production also remained active, given the demand of the two active NPPs. Meanwhile, the National Atomic Energy Commission of Argentina continued the efforts on research and development that were at the base of the technological achievements of the nuclear activities in Argentina. Nuclear safety studies associated with Atucha II and Embalse NPPs and radiological safety were also a substantive part of the continued efforts by Nucleo-Electrica de Argentina SA and the Nuclear Regulatory Authority of Argentina

    This paper reports that security is defined in different ways by many international actors. To some, security is tied to the definition of an external threat to borders, as in the case of the NATO countries. To other, security is related to development, as in the case of most Third World countries. but notwithstanding different definitions, all countries recognize that the essence of security is the survival of the nation-state itself. The nuclear programs of Argentina and Brazil are among the oldest, most sophisticated and advanced nuclear programs anywhere in the Third World. The programs have never been explained on the basis of threat perception, and in this regard perhaps they constitute the most atypical form of nuclear proliferation known to date. Not surprisingly, any attempt to explain the rationale for the Brazilian and Argentine nuclear programs based on common issues of threat =merely confuses the issue. Thus, nationalism, the search for national identity and pride, the need to express self-sufficiency and the desire to keep options open in an insecure and evolving world order must all be analyzed to comprehend the likelihood of future types of nuclear proliferation. Meanwhile, the study of the contemporary era of Argentine-Brazilian nuclear rapprochement may provide new insights into the complex reasoning behind the decision of countries to go nuclear

    The Santa Lucia (2008)—one the most recent Argentine meteorite fall, fell in San Juan province, Argentina, on 23 January 2008. Several masses (total ~6 kg) were recovered. Most are totally covered by fusion crust. The exposed interior is of light-grey colour. Chemical data [olivine (Fa24.4) and low-Ca pyroxene (En77.8 Fs20.7 Wo1.6)] indicate that Santa Luica (2008) is a member of the low iron L chondrite group, corresponding to the equilibrated petrologic type 6. The meteorite name was approved by the Nomenclature Committee (NomCom) of the Meteoritical Society (Meteoritic Bulletin, no. 97). We report about the chemical composition of the major mineral phases, its bulk trace element abundance, its noble gas and nitrogen data. The cosmic ray exposure age based on cosmogenic 3He, 21Ne, and 38Ar around 20 Ma is comparable to one peak of L chondrites. The radiogenic K-Ar age of 2.96 Ga, while the young U, Th-He are of 1.2 Ga indicates that Santa Lucia (2008) lost radiogenic 4He more recently. Low cosmogenic (22Ne/21Ne)c and absence of solar wind noble gases are consistent with irradiation in a large body. Heavy noble gases (Ar/Kr/Xe) indicated trapped gases similar to ordinary chondrites. Krypton and neon indicates irradiation in large body, implying large pre-atmospheric meteoroid.

    The presence and levels of polycyclic aromatic hydrocarbons (PAH's) in [sediments and biota from the Port of Salina Cruz, Oaxaca; were evaluated by means of gas capillary chromatography using columns of high resolution. The results show a seasonal variability of the PAH's concentrations in sediments being higher in the port area and lower in oceanic sediments. The increase of the PAH's levels in Crassostrea iridiscens and Penaeus stylirostris is important and related to the bioaccumulation process. The presence of PAH's conformed by 4 y 5 benzene rings in these species must be noted specially because they have carcinogenic properties and their effects on the local fisheries should be considered.

    The objective is to apply a method that allows us to evaluate the diagnostic quality of a public-center of mammography and to validate it. The representative centers of a social class were grouped; this one is evaluated measuring the mechanics, electrics, dosimetrics and personal parameters of the process to get the mammography diagnostic. The original study and the respective report was submitted to the valuation of a panel of experts, who evaluated image, techniques and diagnostics. The equipment and techniques used are described in this case. The judgment of the ACR and the Argentine legislation are applied. The dosimetric results of the mammography practice serve to determine the local reference levels. The people who intervened in the diagnosis are evaluated, as well as the services that can influence it. Seeking the parametric sensibility in relationship with the succeeded and precocious diagnosis, the success of it is confirmed by the panel of experts. We conclude by indicating that the success percentage in the diagnosis is about 98,36%, that there is 100% of coincidence among the perception and the value of the study quality. The valuation of the image reaches 69,2% of the maximum score, and the placement technique, 73,9%. The parametric sensibilities of the principal variables are discussed. (author)

    Full Text Available Coral reefs are quite diverse ecosystems that carry out several ecological functions and plays a relevant socioeconomic role. The artisan fishing of octopi (Octopus spp. is practiced for the survival of part of the inhabitants of Coroa Vermelha community, in the south of the state of Bahia. We intended to study the knowledge of the octopi fishermen of Coroa Vermelha using the comprehensive ethnoecological proposal of Marques. The data were collected between July, 2006 and April, 2008 through direct observation and from interviews with fishermen met by chance and through the "native specialists" criterion. Twenty semi-structured interviews were carried out following an itinerary of pre-established questions about the activity of octopi capture, and the biological and ecological aspects of the resource. The data showed that the fishermen have knowledge about biological and ecological aspects of the octopi. Two capture techniques are used: octopus fishing (polvejamento in the reefs and through diving. Two specific folk are recognized: the "normal octopus" (Octopus insularis and the "east octopus" (Octopus macropus (?. The intervieews demonstrated ecological knowledge sometimes compatible with the scientific literature, mainly in which concerns the trophic ecology and behavior of the octopi.Os recifes de coral são ecossistemas muito diversos que realizam várias funções ecológicas e possuem um relevante papel socioeconômico. A pesca artesanal de polvo (Octopus spp. é realizada para a sobrevivência de uma parte da população da comunidade de Coroa Vermelha, no Sul do Estado da Bahia. A intenção deste estudo foi avaliar o conhecimento dos pescadores de polvos de Coroa Vermelha, usando a proposta da etnoecologia abrangente de Marques. Os dados foram coletados entre julho de 2006 e abril de 2008 através da observação direta e entrevistas com pescadores encontrados oportunisticamente e com os especialistas "nativos". Vinte entrevistas semi-estruturadas foram realizadas seguindo um roteiro de perguntas pré-estabelecidas sobre a atividade de captura polvos, e os aspectos biológicos e ecológicos do recurso capturado. Os dados demonstraram que os pescadores têm conhecimento sobre alguns aspectos biológicos e ecológicos dos polvos. Duas técnicas de captura são utilizadas: pesca sobre o recife (polvejamento e através de mergulho. Dois específicos do povos são reconhecidos: o polvo "normal" (Octopus insularis e o polvo "de leste" (Octopus macropus (?. Os entrevistados demonstraram conhecimento ecológico, por vezes, compatíveis com a literatura científica, principalmente no que diz respeito à ecologia trófica e comportamento dos polvos.

    Full Text Available This study has the objective to describe the reasons that take the aged ones to practice physical activities in the Third Age Groups and the barriers that hinder them. Thirty aged citizens were subject of this research. The methodological approaching was an exploratory descriptive study, in witch was applied a questionnaire about motivation and barriers for the physical activity practice. As result, it was evidenced that the motivation of the aged ones for physical activity practice is related to: To congregate and meet with other people; to feel itself carried through; to feel themselves mentally more alert and to improve and keep the health. As for the barriers, they exist, in diverse aspects: social, physical and psychic. Although they exist, for these aged ones it did not became something that completely hindered them to go to the group and to practice physical activities. In conclusion, although the difficulties that the aged ones find day after day, the motivation and the barriers are related to the perception of each one, which can become an important and definitive factor for the assiduity or desistance of these individuals in the third age group.

    Full Text Available http://dx.doi.org/10.5007/2175-7968.2017v37n1p230 The medical literature consumed and produced by the Oswaldo Cruz Institute and the circulation of its personnel in foreign institutions from its beginnings in 1900 through the Vargas coup d’état in Brazil in 1930 testify to the complex, multilingual and international nature of scientific networking in and beyond the belle époque and challenge notions of behavior associated with colonial economic models. To explore the parameters of the Institute’s early organizational culture with respect to language, three of its publications from this period will be examined: a 1911 promotional booklet in German, which details the Institute’s journal holdings and the publications of its researchers; a 1929 English-language travelogue of leprosy treatment centers worldwide; and the journal Memórias do Instituto Oswaldo Cruz (1909-, which published articles in five languages during this period. The results indicate that the Institute’s flexible, avidly multilingual language policy, partially the result of Brazil’s peripheral, neutral political situation, led to a very strong multilateral position in the scientific community that provided both visibility and recognition as a full peer in the then-internationally emerging field of Tropical Medicine.

    2017-12-01

    Full Text Available The paper discusses cultural words in the Slovenian translation of the novel The Death of Artemio Cruz by Carlos Fuentes. There are a number of cultural words in the analysed text that have no exact equivalents in other languages and cultures. These are also elements that contribute to the foreignization of the target text and show us the textual world as exotic and unknown. However, it is interesting that in a lot of cases the reader does not feel disoriented, because there are enough references in the text that he can understand what is needed. Moreover, the explanations in the footnotes help the reader a lot in those parts where the monologue of Artemio Cruz adopts an essayistic tone and the great questions about Mexico and the Mexicans arise. The reader thus has the feeling that he is losing himself in the whirlwind of Mexican history. These passages are difficult to understand (both in the original and the translation due to the narrative techniques of the author and not so much to the realia. The translator of the studied text, Alenka Bole Vrabec, tends to choose the transfer of cultural words in order to retain some local colour, even when she could find equivalents in Slovenian or, at least, adapt the words to writing in accordance with the rules of the Slovenian language. These decisions accentuate the foreignizing character of the translation.

    2011-01-01

    Triatoma infestans is the main vector of Chagas' disease in South America between latitudes 10°S and 46°S. A multilocus microsatellite data set of 836 individuals from 27 populations of T. infestans, from all its range of distribution in Argentina, was analyzed. Our results favor the hypothesis of two independent migration events of colonization in Argentina and secondary contacts. The majority of the populations of the western provinces of Catamarca, La Rioja, San Juan and the west of Cordoba province, had almost no shared ancestry with the rest of the populations analyzed. Probably those populations, belonging to localities close to the Andean region, could have been established by the dispersal line of T. infestans that would have arrived to Argentina through the Andes, whereas most of the rest of the populations analyzed may have derived from the dispersal line of T. infestans in non-Andean lowlands. Among them, those from the provinces of Formosa, Chaco, Santiago del Estero and Santa Fe shared different percentages of ancestry and presented lower degree of genetic differentiation. The migratory movement linked to regional economies and possibly associated with passive dispersal, would allow a higher genetic exchange among these populations of T. infestans. This study, using microsatellite markers, provides a new approach for evaluating the validity of the different hypotheses concerning the evolutionary history of this species. Two major lineages of T. infestans, an Andean and non-Andean, are suggested. PMID:21224874

    The mullet Mugil liza is distributed along the Atlantic coast of South America, from Argentina to Venezuela, and it is heavily exploited in Brazil. We assessed patterns of distribution of neutral nuclear genetic variation in 250 samples from the Brazilian states of Rio de Janeiro, São Paulo, Santa Catarina and Rio Grande do Sul (latitudinal range of 23-31°S) and from Buenos Aires Province in Argentina (36°S). Nine microsatellite loci revealed 131 total alleles, 3-23 alleles per locus, He: 0.69 and Ho: 0.67. Significant genetic differentiation was observed between Rio de Janeiro samples (23°S) and those from all other locations, as indicated by FST, hierarchical analyses of genetic structure, Bayesian cluster analyses and assignment tests. The presence of two different demographic clusters better explains the allelic diversity observed in mullets from the southernmost portion of the Atlantic coast of Brazil and from Argentina. This may be taken into account when designing fisheries management plans involving Brazilian, Uruguayan and Argentinean M. liza populations.

    Prevalence of anthrax spores in feces of raptors was determined from samples collected in November-December 2000 and April-May 2001 in an agricultural region of Santa Fé province, Argentina. Feces were tested from 48 birds of six raptor species. One of 14 chimango caracaras (Milvago chimango) and one of eight road-side hawks (Buteo magnirostris) tested positive. The prevalence of Bacillus anthracis spores in feces for the six species was 4% (n=48). The prevalence was 7% (n=14) for chimango caracaras, 13% for road-side hawks (n=8), and 0% for the remaining species (Burrowing owl [Speotyto cunicularia] [n=17], Swainson's hawk [Buteo swainsoni] [n=3], Aplomado falcon [Falco femoralis] [n=2], and American kestrel [Falco sparverius] [n=4]). Grouped by their feeding habits, prevalence for scavenger species was not significantly different than for predators (7% vs. 3%, P>0.999). This study provides evidence that in central Argentina scavenger and non-scavenger raptors may have a role in the epidemiology of anthrax. Long-term studies to determine the extent of this potential involvement in the epidemiology of anthrax in central Argentina are required.

In addition, we examine carefully and systematically the evident relations between the fraternity of the True Cross in Bilbao and the fraternity of the True Cross in Vitoria, for whose foundation in 1538 there is documented evidence. This study shows that the statutes of the fraternity of the True Cross in the town of Vitoria were taken into account by those who decided to set up the same fraternity in the town of Bilbao in the middle of the sixteenth century.En este artículo se analiza y valora el período en que se produjeron en el País Vasco las primeras fundaciones de las Hermandades y Cofradías de la Vera Cruz, así como la importancia que tuvo el culto a la Cruz en este territorio. Al mismo tiempo se examinan, de manera más precisa y sistemática, las relaciones manifiestas de la cofradía de la Vera Cruz de Bilbao con la cofradía de la Vera Cruz de Vitoria, cuya fundación está documentada en 1538. De este estudio se deriva que los estatutos de la cofradía de la Vera Cruz de la ciudad de Vitoria fueron tenidos en cuenta por quienes en la villa de Bilbao decidieron instituir dicha cofradía a mediados del siglo XVI.

    2016-01-01

    This article first outlines that Argentina produces an important part of its hydrocarbon consumption and comment various aspects of this production: hydrocarbons are at the heart of the Argentinian energetic model; conventional hydrocarbon reserves are however decreasing; the public operator remains the main actor even though the market is opened to multinational companies. The article then describes the crisis faced by this energetic model: the energy balance is now a burden; the increasing unbalance between production and consumption can be explained by supply-related as well as demand-related factors; authorities must intervene on hydrocarbon prices and subsidize the oil price on the domestic market. It appears that the future for hydrocarbons in Argentina relies on non-conventional hydrocarbons. Bio-fuels, a key sector of the Argentinian economy, are a matter of trade dispute with the EU and the USA. Apart from hydroelectricity (some new projects are planned), renewable energies are very few developed in Argentina. Appendices propose a graph of the distribution of energy consumption among the different sources, a map indicating locations of the main exploited hydrocarbon deposits, a presentation of mechanisms implemented to subsidize hydrocarbon production

    2011-12-01

    Full Text Available Knowledge of intensity-duration-frequency (IDF relationships of rainfall events is extremely important to determine the dimensions of surface drainage structures and soil erosion control. The purpose of this study was to obtain IDF equations of 13 rain gauge stations in the state of Santa Catarina in Brazil: Chapecó, Urussanga, Campos Novos, Florianópolis, Lages, Caçador, Itajaí, Itá, Ponte Serrada, Porto União, Videira, Laguna and São Joaquim. The daily rainfall data charts of each station were digitized and then the annual maximum rainfall series were determined for durations ranging from 5 to 1440 min. Based on these, with the Gumbel-Chow distribution, the maximum rainfall was estimated for durations ranging from 5 min to 24 h, considering return periods of 2, 5, 10, 20, 25, 50, and 100 years,. Data agreement with the Gumbel-Chow model was verified by the Kolmogorov-Smirnov test, at 5 % significance level. For each rain gauge station, two IDF equations of rainfall events were adjusted, one for durations from 5 to 120 min and the other from 120 to 1440 min. The results show a high variability in maximum intensity of rainfall events among the studied stations. Highest values of coefficients of variation in the annual maximum series of rainfall were observed for durations of over 600 min at the stations of the coastal region of Santa Catarina.

    The life of Giovanni Cingolani (Montecassiano, 1859 – Santa Fe, 1932 takes place between Italy and Argentina at the turn of the 19th and 20th centuries. Cingolani redeems his humble origins with a successful career as a painter and restorer in Rome between 1880 and 1908. Thanks to the relations with prelates and painters of Perugia, close to Pope Leo XIII, the artist fits himself in the papal circles, devoting himself to painting religious and to the portrait. Came into contact with Ludovico Seitz, director of the Vatican Museums, participates in the major restorations in the Borgia apartment, in the chapel Niccolina, in the Vatican Stanze and in the Sistine Chapel. In 1909 he emigrated to Santa Fe, where he worked as a church decorator and portrait painter, devoting himself intensely to teaching: thanks to unpublished documents, especially the correspondence between Cingolani, his daughter Leonilde and the director of the library of Macerata, Giovanni Spadoni, you can learn many details about his life and the Italian and Argentines artistic milieus he frequented. The paper wants to disclose this almost unknown artist, “migrant” between Italy and Argentina, highlighting his role of disseminator of European academic tradition in Latin America.

    Full Text Available Transforming mature tourism resorts has evolved toward a greater involvement of public authorities and away from the mere renovation of public spaces. Authorities today are required to lead the reorganization of tourism activities through the development of co-operative networks between all stakeholders involved. In this paper, a participatory integrated approach has been designed and implemented in collaboration with Spanish authorities and the tourism sector to propose a strategy to achieve the renovation of tourism resorts. This methodology was applied to Puerto de la Cruz, the oldest tourism destination in the Canary Islands and a clear paradigm of a consolidated resort. The objective is to define and implement policies to transform Puerto de la Cruz into a more sustainable tourism destination.

    The article analyzes reports from two scientific journeys into the Amazon conducted by the Instituto Oswaldo Cruz, in 1910 and 1913, under the leadership of Oswaldo Cruz and Carlos Chagas, respectively. These reports contributed to the construction of representations and images of the region. Field observations not only provided data for the study and control of tropical diseases but also had a hand in the movement to denounce the serious sanitation conditions under which rubber workers labored. Journeys through the Amazon valley put the scientists in direct contact with the environment and with sick populations; these travels also made them face the huge challenges of learning about malaria and trying to control it. Analyses of these reports are part of studies on 'portraits of Brazil', which raise issues within the history of public health policies. In this endeavor to reveal the process by which scientific records are constructed, we worked with primary sources,from manuscripts to official texts.

    Full Text Available Este trabajo presenta las características e historia del software para crear y gestionar bibliotecas digitales Greenstone, desarrollado inicialmente por la Universidad de Waikato, Nueva Zelandia en 1997. En primer lugar, se describe la comunidad de usuarios a nivel global, focalizando en el uso actual que el software ha alcanzado en Argentina: la cantidad de implementaciones disponibles, su evolución, el tipo, tamaño y variedad de los desarrollos existentes, así como su aplicación a la gestión de repositorios digitales de ciencia y tecnología en el ámbito de las instituciones científicas, tecnológicas y de educación superior en Argentina. En segundo lugar, se detallan las acciones llevadas a cabo a partir de la creación del Centro Nacional de Promoción de Greenstone en Argentina en 2009. Datos recabados en encuestas realizadas permitieron observar que las razones predominantes para elegir esta plataforma fueron, entre otras, su facilidad de instalación y configuración, su bajo nivel de requerimiento tecnológico, la generalizada escasez de recursos humanos dedicados a esta actividad, y la complejidad que presentaban los softwares alternativos existentes en ese momento. A lo largo de estos 8 años, tanto los repositorios digitales como los sistemas que los soportan evolucionaron drásticamente, modificando el escenario actual. Paralelamente, en 2016 la nueva versión mayor de Greenstone implementó una reingeniería completa del software para su adaptación a las tecnologías en uso: XML, XSLT, Web-services y Java. Como consecuencia de esto, la comunidad de desarrollo local se plantea nuevos desafíos para la migración de las bibliotecas digitales y repositorios implementados con versiones anteriores.

All violate the copyright of the software/music/film owners, and copyright owners are not Santa Claus...    CERN, like other research organisations and universities, regularly receives allegations from external companies complaining about laptops or PCs running illegal software or sharing their films, videos or music with peers – and thus violating copyright.  Usually, we then contact the owners of the corresponding devices in order to understand whether these allegations are true. Very often such allegations boil down to a laptop whose owner replies “I confirm that a torrent client was left up and running on my device by mistake” or “This is a file that is stored on my personal hard disk.” As if those allegatio...

    Plate interaction between Caribbean and Nazca plates with Southamerica gave rise to an intricate pattern of tectonic blocks in the Northandean realm. Among these microblocks the Sierra Nevada de Santa Marta (SNSM) represents a fault-bounded triangular massif composed of a representative crustal section of the Northandean margin, in which a Precambrian to Late Paleozoic metamorphic belt is overlain by a Triassic to Jurassic magmatic arc and collateral volcanic suites. Its western border fault belongs to the composite Bucaramanga - Santa Marta fault with a combined left lateral-normal displacement. SE of Santa Marta it exposes remnants of an Oligocene marginal basin, which attests to a first Cenoizoic activation of this crustal-scale lineament. The basin fill consists of a sequence of coarse-grained cobble-pebble conglomerates > 1000 m thick that unconformably overlay the Triassic-Jurassic magmatic arc. Its lower sequence is composed of interbedded siltstones; topwards the sequence becomes dominated by coarser fractions. These sedimentary sequences yields valuable information about exhumation and coeval sedimentation processes that affected the massif's western border since the Upper Eocene. In order to analyse uplifting processes associated with tectonics during early Neogene we performed detrital zircon U-Pb geochronology, detrital thermochronology of zircon and apatites coupled with the description of a stratigraphic section and its facies composition. We compared samples from the Aracataca basin with analog sequences found at an equivalent basin at the Oca Fault at the northern margin of the SNSM. Our results show that sediments of both basins were sourced from Precambrian gneisses, along with Mesozoic acid to intermediate plutons; sedimentation started in the Upper Eocene-Oligocene according to palynomorphs, subsequently in the Upper Oligocene a completion of Jurassic to Cretaceous sources was followed by an increase of Precambrian input that became the dominant

    Evidence has been obtained for the biosynthesis of 'fructans' in Agave vera cruz. A hydrolase-free enzyme preparation from the stem juice with U-/sup 14/C sucrose as substrate and the native fructan as primer leads to incorporation of /sup 14/C fructose into a polymer like compound. This inference is based on criteria such as the chromatographic mobility of the product and the elution volume from a Sephadex G-25 column. Two optimum pHs 4.9 and 6.1 and optimum temperature 377degC are observed for the reaction. The activity is dependent on primer, enzyme, substrate concentration and duration of incubation. The ratio of substrate to primer appears to be a special factor; higher ratios retard synthesis (S:P 5:1, 1.14%, S:P 100:1, 0.36% incorporation), while lower ones enhance (reaching a maximum of 11.35% at an S:P ratio of 1.75 in hr). Inulin in place of the native fructan is less efficient as primer. Each of the higher homologues of sucrose, tri to hexasaccharides (tested so far), leads to fructan formation with elution volumes from a Sephadex G-25 column close to that of the primer. U-/sup 14/C fructose or glucose in place of U-/sup 14/C sucrose or absence of enzyme leads to no incorporation. Sucrose seems to have a key role both in the initiation and lengthening of the fructan chain.

    The paper discusses the results of research into user satisfaction in three healthcare facilities at Oswaldo Cruz Foundation in Rio de Janeiro. The analysis is based on the concepts of user satisfaction and responsiveness. Perceptions and opinions of outpatients from Instituto de Pesquisa Evandro Chagas, Instituto Fernandes Figueira and Centro de Saúde Escola Germano Sinval Faria were investigated. Intention samples were drawn for each institution and a total of 1.339 valid questionnaires were obtained. The study found that patients are satisfied with healthcare at Fiocruz, especially with health professionals. Nevertheless, restroom hygiene and privacy during consultations were less well evaluated. The improvement of these aspects depends not only on financial and technological investments but on changes in organizational culture. The first part of the paper discusses the literature on user satisfaction and responsiveness, with the definition of the categories that guided the study. The methodology is then presented as well as the four health services dimensions assessed - dignity, agility, facilities and communication - and the results are analyzed.

    Miyara, Federico

    2002-11-01

    Over the last decades, education in acoustics (EA) in Argentina has experienced ups and downs due to economic and political issues interfering with long term projects. Unlike other countries, like Chile, where EA has reached maturity in spite of the acoustical industry having shown little development, Argentina has several well-established manufacturers of acoustic materials and equipment but no specific career with a major in acoustics. At the university level, acoustics is taught as a complementary--often elective--course for careers such as architecture, communication engineering, or music. In spite of this there are several research centers with programs covering environmental and community noise, effects of noise on man, acoustic signal processing, musical acoustics and acoustic emission, and several national and international meetings are held each year in which results are communicated and discussed. Several books on a variety of topics such as sound system, architectural acoustics, and noise control have been published as well. Another chapter in EA is technical and vocational education, ranging between secondary and postsecondary levels, with technical training on sound system operation or design. Over the last years there have been several attempts to implement master degrees in acoustics or audio engineering, with little or no success.

It was based on diagnosis of conceptions of health, concentration of fluoride in drinking water and accessibility to dental coverage in 71 rural schools. Additionally, parents and teachers’ conceptions of general and oral health, dental clinical status and sialochemistry of students from eight schools were considered. Objective: To evaluate a community intervention strategy for promoting oral health in rural contexts. Through the participation of the teacher as a mediator of healthy pattern, this strategy was developed. Methods: In order to elaborate oral health promoting strategies, educational workshops, epistolary communication and on site tutorials meetings were implemented. Specific health projects to be added to the Educational Institutional Programs, as a contextualized mediating strategy for promoting oral health were designed by teachers. The strategy was evaluated comparing dental caries increase (CI detected the previous year and the one following the implementation of the educational plans. Mac Nemar's test was applied, and p<0.05 was set to indicate statistical differences between both periods. Results: A 30.43% CI (p<0.0001 was observed the year before implementing the educational programs as well as a CI reduction to 17.39% (p=0.0002 a year after their application. Conclusion: The drop off in 57.14% of the CI in rural areas, confirms the intervention strategy of designed for this particular context.Keywords: community intervention, oral health promotion, rural communities.

El interés es analizar cómo los procesos locales y globales inciden en la configuración de modalidades turísticas, a partir de la selección y mercantilización de elementos “naturales” (rurales e históricos-culturales. La investigación aquí expuesta se construyó a través del trabajo de campo realizado en el periodo 2011-2015 en la ciudad cabecera, Capilla del Señor. Allí se observó que los criterios establecidos en los procesos de patrimonialización fueron implementados para construir, en una primera etapa, un turismo “cultural” que permitió consolidar determinados discursos y representaciones de la ciudad. A su vez, se constata que la práctica turística utiliza pautas más flexibles, al adecuarse a las demandas del mercado turístico global, llevando a incluir, en una segunda etapa, elementos vinculados con la ruralidad del partido, los cuales eran desestimados anteriormente.

    Full Text Available En este artículo se describe el sistema de salud de Argentina, que está compuesto por tres sectores: público, de seguridad social y privado. El sector público está integrado por los ministerios nacional y provincial, y la red de hospitales y centros de salud públicos que prestan atención gratuita a toda persona que lo demande, fundamentalmente a personas sin seguridad social y sin capacidad de pago. Se financia con recursos fiscales y recibe pagos ocasionales de parte del sistema de seguridad social cuando atiende a sus afiliados. El sector del seguro social obligatorio está organizado en torno a las Obras Sociales (OS, que aseguran y prestan servicios a los trabajadores y sus familias. La mayoría de las OS operan a través de contratos con prestadores privados y se financian con contribuciones de los trabajadores y patronales. El sector privado está conformado por profesionales de la salud y establecimientos que atienden a demandantes individuales, a los beneficiarios de las OS y de los seguros privados. Este sector también incluye entidades de seguro voluntario llamadas Empresas de Medicina Prepaga que se financian sobre todo con primas que pagan las familias y/o las empresas. En este trabajo también se describen las innovaciones recientes en el sistema de salud, incluyendo el Programa Remediar.This paper describes the health system of Argentina.This system has three sectors: public, social security and private.The public sector includes the national and provincial ministries as well as the network of public hospitals and primary health care units which provide care to the poor and uninsured population. This sector is financed with taxes and payments made by social security beneficiaries that use public health care facilities. The social security sector or Obras Sociales (OS covers all workers of the formal economy and their families. Most OS operate through contracts with private providers and are financed with payroll

    Argentina's Congress has voted to fully privatize state petroleum company Yacimientos Petroliferos Fiscales (YPF), a move the government expects to net at least $8 billion. Despite some political opposition, the vote was 119-10 in favor, with one abstention and opposition party members refusing to participate in the vote. Argentina's President Carlos Menem had threatened to authorize YPF privatization by decree if there was no quorum for a vote. YPF is responsible for 40% of Argentina's oil production. The country h as been self-sufficient in crude since 1982. Current production is 563,472 b/d, and proved reserves of oil and gas are valued at $7 billion

    Full Text Available Chytridiomycosis, a disease caused by the chytrid fungus Batrachochytrium dendrobatidis (B.d., is recognized as one of the major factors of amphibian decline. Global trade of amphibians has been identified as one of the causes of B.d. spread, involving hundreds of species world wide. In this work we detected the presence of B.d. through histological examination on 5 out of 9 analyzed specimens of bullfrogs (Lithobates catesbeianus from a farm in Santa Fe City (Argentina, deposited since 1993 in the herpetological collection of the Provincial Museum of Natural Sciences "Florentino Ameghino". Our finding represents the oldest record of B.d. for Argentina and the first case of the chytrid fungus infecting the exotic bullfrog in this country. We emphasize the importance of determining and monitoring the distribution and spread of B.d in Argentina, particularly in areas where feral bullfrog populations have already been identified.La quitridiomicosis, enfermedad emergente producida por el hongo Batrachochytrium dendrobatidis (B.d., es reconocida como uno de los factores causantes de la declinación de anfibios. El comercio mundial de anfibios ha sido señalado como una de las fuentes de dispersión de B.d. En este trabajo se detectó la presencia de B.d. en la especie exótica rana toro (Lithobates catesbeianus mediante cortes histológicos en 5 de 9 ejemplares provenientes de un criadero de la ciudad de Santa Fe (Argentina, depositados y conservados desde 1993 en la Colección Herpetológica del Museo Provincial de Ciencias Naturales "Florentino Ameghino". Este registro representa el hallazgo más antiguo de B.d. en Argentina y el primer caso de este hongo en la rana toro exótica en el país; por lo que enfatizamos la importancia de determinar y monitorear la distribución y dispersión de B.d., particularmente en los sitios donde ya se han detectado poblaciones silvestres de rana toro.

    Describe alcohol consumption by Argentine women before and during pregnancy and identify the factors associated with consumption- and pregnancy-related changes. Cross-sectional observational study. Women were interviewed after giving birth and receiving care at two perinatal health care centers in Santa Fe, Argentina. Sociodemographic information, data on their alcohol use, and other information were obtained from the participants. A descriptive analysis of consumption prevalence rates was made and the factors associated with patterns of alcohol use were identified by means of repeated measure analysis. Of the 614 participants, 75.2% had had at least one alcoholic drink (standard unit) during pregnancy and 83.3% had done so in the previous year; 15.1% admitted having at least one episode of binge drinking (five or more drinks) during pregnancy and 27.6% in the year prior to pregnancy. Only 30.6% of the women said they had made any change in consumption during the previous year; of those, 55.6% reduced their consumption and 41.8% stopped drinking. Women who consumed the most alcohol before and during pregnancy reported higher consumption by their partners, smoked, and had more permissive attitudes about alcohol use during pregnancy. A specific prevention plan is required in Argentina to reduce alcohol use in pregnant women, adjusted to local patterns of use, with interventions that include couples, and focused on the youngest women, those who use tobacco, and those who have more permissive attitudes about alcohol use.

    Data collected 10 years ago in Argentina concluded that women in physics were underrepresented in many instances and that a "crystal ceiling" was firmly in place. We have collected updated data for several indicators and compared them with those obtained 10 years ago. Although there is not a clear conclusion to be drawn from this comparison, we try to explain the results within the framework of the changes in scientific policies in Argentina.

  18. Poverty and Health in Argentina

    Full Text Available This article examines health conditions in the rural areas of Central Argentina, the country’s main region for soy-bean production and export. Health conditions are analyzed through the concepts of emerging and re-emerging diseases in a context of increasing poverty. Data on poverty and health was obtained from both primary sources (trade union, government officials, rural doctors and the South Watch/FA/FODEPAL/UNR working group and secondary sources (IPEC/INDEC, IDESA, Consultora Equis, the Argentine Ministry of Employment, ILO, the Ministry of Health, the Ministry of the Environment, toxicology centers and rural doctors. Analysis of rural health conditions gives cause for concern. There is evidence of deterioration in the social determinants of health such as an increase in rural and urban poverty associated with informal employment and child labor. At the same time lack of government epidemiological and toxicological data appears to hide or distort the reality of health conditions.
