    The investigation of hunter-gatherers archaeological sites in the Limay river basin, Patagonia, Argentina, raised questions concerning the lithic technology. The chemical characterization of artifacts, rocks and possible sources of provenances could help to elucidate the hunter-gatherer mobility. In three archaeological sites-Rincon Chico 2 (RCh2/87; 14 C 710 ± 60 BP), Cueva Traful I (CTI; 14 C 9430 ± 230 BP) and Casa de Piedra de Ortega (CPO; 14 C 2840 ± 80 BP), tools and debitage or discarded flakes made in black volcanic rock have been found. Nearby an extensive rock outcrop of black volcanite, Paso Limay quarry (CPL), with similar characteristics was located. Samples coming from these four sites were analyzed by energy dispersive X-ray fluorescence spectrometry. This characterization allowed the geochemical classification of the lithic material and to correlate the samples with the suspected source after a previous statistical analysis. The majority of the samples were classified as dacites and rhyolites. Only samples coming from CPO site, the closest place to CPL were made exclusively with the quarry rocks. A set of five samples from RCh2/87 and two samples from CTI appear to have same chemical composition as CPL in spite of this site is placed in the opposite bank of the Limay river suggesting that hunter-gatherers could accede to the quarry, eventually. Finally, only a set of five samples coming from RCh2/87 and CTI do not group with the quarry. This fact evidences the existence of secondary sources of supply. The information of this research allowed inferring ancient human mobility patterns in the region. (author)

    We documented arroyo evolution at the tree, trench, and arroyo scales along the lower Rio Puerco and Chaco Wash in northern New Mexico, USA. We excavated 29 buried living woody plants and used burial signatures in their annual rings to date stratigraphy in four trenches across the arroyos. Then, we reconstructed the history of arroyo evolution by combining trench data with arroyo-scale information from aerial imagery, light detection and ranging (LiDAR), longitudinal profiles, and repeat surveys of cross sections. Burial signatures in annual rings of salt cedar and willow dated sedimentary beds greater than 30 cm thick with annual precision. Along both arroyos, incision occurred until the 1930s in association with extreme high flows, and subsequent filling involved vegetation development, channel narrowing, increased sinuosity, and finally vertical aggradation. A strongly depositional sediment transport regime interacted with floodplain shrubs to produce a characteristic narrow, trapezoidal channel. The 55 km study reach along the Rio Puerco demonstrated upstream progression of arroyo widening and filling, but not of arroyo incision, channel narrowing, or floodplain vegetation development. We conclude that the occurrence of upstream progression within large basins like the Rio Puerco makes precise synchrony across basins impossible. Arroyo wall retreat is now mostly limited to locations where meanders impinge on the arroyo wall, forming hairpin bends, for which entry to and exit from the wall are stationary. Average annual sediment storage within the Rio Puerco study reach between 1955 and 2005 was 4.8 × 105 t/yr, 16% of the average annual suspended sediment yield, and 24% of the long-term bedrock denudation rate. At this rate, the arroyo would fill in 310 yr.

    A 4π position-sensitive heavy-ion detector system, CHICO, has been developed primarily for use in conjunction with the 4π γ-ray facility, Gammasphere. The CHICO detector comprises an array of 20 Parallel Plate Avalanche Counters (PPACs) covering 12 deg. <θ<85 deg. and 95 deg. <θ<168 deg. and 280 deg. in phi. The PPACs have segmented delay-line cathode boards, measuring the polar scattering angle θ to 1 deg., and segmented anodes, measuring the azimuthal angle phi with 9 deg. resolution, while measuring the time-of-flight difference with 500 ps resolution. For binary reactions the kinematics can be reconstructed from the measured information, allowing identification of the target- and projectile-like nuclei with a mass resolution of Δm/m∼5%. The measured masses, recoil velocities, and recoil angles allow correction for Doppler shift and assignment of individual γ-rays to decay of the correct reaction product. This paper describes the design, operation and performance of the CHICO detector. The powerful combination of CHICO plus Gammasphere provides new research opportunities for the study of nuclear structure and reactions

    Holmium-166-chitosan complex (Ho-166-chico) is injected into the unresectable seven cystic brain tumors (2 cases of metastatic brain tumors from lung cancer, 1 case of recurrent trigeminal neurinoma, 3 cases of recurrent low grade cystic astrocytomas, and 1 case of craniopharyngioma). The Ommaya reservoir was installed stereotactically. The cyst volume and wall thickness were measured by MRI before Ho-166-chico injection. The thickness of the cyst wall is up to 4 mm. Ho-166-chico (555-740 MBq) injected into the cyst to result in 25 Gy of dose to a cyst wall at a depth of 4 mm. Dose to the cyst wall was estimated by Monte Carlo simulation using the EGS4 code. All Ho-166-chico injected was assumed to be uniformly distributed in the spherical cyst. After Ho-166-chico injection, the distribution of isotopes was monitored by gamma camera. Two injections were administrated in two cases, and one injection in all the others. The response was evaluated with MRI. Four of 7 cases were shrunk in size with thinning of the cyst wall, 2 of 7 cases showed growth arrest, and one case showed progression. Estimated surface dose of cyst wall was between 78 and 2566 Gy. No one showed systemic absorption of Ho-166-chico, and specific complication associated with isotope injection. Ho-166-chico intracavitary radiation therapy for cystic brain tumor may be safe, and reliable method and deserves further evaluation.

    The lithostratigraphy of the Vendian to Lower Cambrian Arroyo del Soldado Group of the Nico Perez Terrane is presented. The Yerbal Formation is defined and the Barriga Negra Formation is included in the Group. The Arroyo del Soldado Group represents a transgressive - regressive sequence developed on a passive continental margin, reaching a thickness of 5000m. The lithofacies succession is mainly explained by the combination of tectonic processes, global climatic - and sea level changes. Its geographic extension allows the determination of the eastern and southern boundaries of the Nico Perez Terrane. The known surface of this Terrane is therefore considerably increased. Several outcroups previously assigned to the Lavalleja Group are in this paper included in the Arroyo del Soldado Group, using sedimentalogical and paleontological criteria

  11. Drosophila Longevity Assurance Conferred by Reduced Insulin Receptor Substrate Chico Partially Requires d4eBP.

    Directory of Open Access Journals (Sweden)

    Hua Bai

    Full Text Available Mutations of the insulin/IGF signaling (IIS pathway extend Drosophila lifespan. Based on genetic epistasis analyses, this longevity assurance is attributed to downstream effects of the FOXO transcription factor. However, as reported FOXO accounts for only a portion of the observed longevity benefit, suggesting there are additional outputs of IIS to mediate aging. One candidate is target of rapamycin complex 1 (TORC1. Reduced TORC1 activity is reported to slow aging, whereas reduced IIS is reported to repress TORC1 activity. The eukaryotic translation initiation factor 4E binding protein (4E-BP is repressed by TORC1, and activated 4E-BP is reported to increase Drosophila lifespan. Here we use genetic epistasis analyses to test whether longevity assurance mutants of chico, the Drosophila insulin receptor substrate homolog, require Drosophila d4eBP to slow aging. In chico heterozygotes, which are robustly long-lived, d4eBP is required but not sufficient to slow aging. Remarkably, d4eBP is not required or sufficient for chico homozygotes to extend longevity. Likewise, chico heterozygote females partially require d4eBP to preserve age-dependent locomotion, and both chico genotypes require d4eBP to improve stress-resistance. Reproduction and most measures of growth affected by either chico genotype are always independent of d4eBP. In females, chico heterozygotes paradoxically produce more rather than less phosphorylated 4E-BP (p4E-BP. Altered IRS function within the IIS pathway of Drosophila appears to have partial, conditional capacity to regulate aging through an unconventional interaction with 4E-BP.

    In 1953, a programme to control schistosomiasis mansoni was started in Guayama and Arroyo, Puerto Rico, employing, first, chemical and, later, both biological and chemical methods to control Biomphalaria glabrata, the snail host of Schistosoma mansoni. Sodium pentachlorophenate was the molluscicide, and an ampullarid snail, Marisa cornuarietis, was used for biological control in ponds and reservoirs. In addition some chemotherapy was given to infected persons. The prevalence of intestinal schistosomiasis was measured annually, sampling about one-third of the 6-year-old population in Guayama and Arroyo and in Caguas, an untreated area. Costs of the programme and the results are discussed in relation to similar projects in other parts of Puerto Rico. In Guayama and Arroyo the prevalence of schistosomiasis reached zero in 6-year-olds by 1966 despite the persistence of the disease in a nearby untreated area. Although this decline appeared related to the control effort, it is noted that a large decline also occurred in the untreated area, suggesting the influence of other factors such as economic development or improvements in sanitation.

    Arroyos in the Southwestern United States have experienced multiple cut-and-fill cycles in the late Quaternary. Extensive studies fo the Lower Rio Puerco, New Mexico, USA, show that it has most recently progressed from an (1) unincised state with a broad floodplain in the mid 1800s, through a period of (2) incision, forming a deep gully with steep walls by the early 1900s, and to the (3) present-day stage of arroyo widening and filling. The arroyo cycle is driven by a combination of autogenic processes and external forcings, although the relative influence of each process is under debate. We use the morphodynamic model ANUGA to explore the influences of discharge, sediment transport, and vegetation on the geomorphic evolution of the Lower Rio Puerco through the arroyo cycle. The predictive power of the numerical model is first established by using it to hind-cast the morphologic evolution of a reach of the river during a large flood in 2006, and comparing the model predictions to real-world magnitudes and patterns of topographic change recorded for this event by multi-temporal airborne lidar. The morphodynamic model is then used to simulate the response of this stream to floods in the past. A comprehensive dataset of the topography and hydrology of the Lower Rio Puerco since the 1920s is used to reproduce the morphology of the arroyo at multiple points in time, and historical descriptions serve to extrapolate these into the 19th century. We test the sensitivity of the reconstructed landscapes to changes in peak discharge, sediment supply, and the distribution and characteristics of vegetation in order to determine the relative influence of each forcing in the evolution of the stream, and to understand how the interactions of different processes could drive its progression through the arroyo cycle.

    IntroductionArroyo Seco is a river that flows eastward out of the Santa Lucia Range in Monterey County, California. The Santa Lucia Range is considered part of the central California Coast Range. Arroyo Seco flows out of the Santa Lucia Range into the Salinas River valley, near the town of Greenfield, where it joins the Salinas River. The Salinas River flows north into Monterey Bay about 40 miles from where it merges with Arroyo Seco. In the mountain range, Arroyo Seco has cut or eroded a broad and deep valley. This valley preserves a geologic story in the landscape that is influenced by both fault-controlled mountain building (tectonics) and sea level fluctuations (regional climate).Broad flat surfaces called river terraces, once eroded by Arroyo Seco, can be observed along the modern drainage. In the valley, terraces are also preserved like climbing stairs up to 1,800 feet above Arroyo Seco today. These terraces mark where Arroyo Seco once flowed.The terraces were formed by the river because no matter how high they are, the terraces are covered by gravel deposits exactly like those that can be observed in the river today. The Santa Lucia Range, Arroyo Seco, and the Salinas River valley must have looked very different when the highest and oldest terraces were forming. The Santa Lucia Range may have been lower, the Arroyo Seco may have been steeper and wider, and the Salinas River valley may have been much smaller.Arroyo Seco, like all rivers, is always changing. Some-times rivers flow very straight, and sometimes they are curvy. Sometimes rivers are cutting down or eroding the landscape, and sometimes they are not eroding but depositing material. Sometimes rivers are neither eroding nor transporting material. The influences that change the behavior of Arroyo Seco are mountain uplift caused by fault moment and sea level changes driven by regional climate change. When a stream is affected by one or both of these influences, the stream accommodates the change by

    As having used Ho-166 Chitosan complex, this study was designed for the development of new therapeutic agent in the treatment of liver cancer (hepatocellular carcinoma). During the period of 3 years from April 1, 1997 to March 31, 2000, this project was successfully performed on the base of clinical experience with percutaneous Ho-166 CHICO injection in the treatment of liver cancer'. In order to evaluate the biodistribution and effect of Ho-166 CHICO was performed in 50 patients, who had the progressed liver cancer with range of 3-10cm in diameter. After the administration of the complex materials, we evaluated the therapeutic effect as well as complication by the follow-up study that included laboratory examination, radioactivity counting and various imaging modalities. 1) In animal experiment, radioactivity of target liver was ranged between 27-33% of total body one, urine excretion between 0.17-0.24 %. White blood cell and platelet counts start diminishing within 7 days and at maximum within 4 weeks after administration of complex materials. In tissue changes of target liver was revealed no significant change in the tumor dose of Ho-166, but periportal fibrosis and massive tissue necrosis in the high ones. 2) In clinical study, total necrosis of tumor is 66%, partial 10% and non-response 24% among 50 patients' liver cancer. The most important complication were leukopenia and thrombocytopenia (82%), the remained was abdominal pain(34%), skin reaction(12%), bile duct obstruction(10%), liver abscess(6%) etc. Conclusively intraarterial injection of Ho-166 CHICO was effective in the treatment of larger and progressed liver cancer. 19 refs., 14 figs., 8 tabs.

    Salinity and dissolved selenium are known water-quality impairments in the lower Gunnison River watershed of western Colorado. Salinity is a concern because of its adverse effects on agricultural land and equipment, and on municipal and industrial users. The Montrose Arroyo watershed in Montrose, Colorado, contains agricultural and residential areas as well as undeveloped land and has undergone substantial land-use change since the early 1990s. Previous sampling efforts indicated salinity concentrations and loads have remained constant since land-use change began in the early 1990s; however, recent sampling also indicated that dissolved-selenium concentrations and loads have begun to increase. In response to the potential increasing dissolved-selenium concentrations and loads, the U.S. Geological Survey—in cooperation with the Bureau of Reclamation; Colorado River Basin Salinity Control Forum; and Colorado River Water Conservation District—continued to monitor salinity and dissolved-selenium concentrations and loads in the Montrose Arroyo watershed. This report characterizes salinity and dissolved-selenium loads in Montrose Arroyo from 1992 to 2013 at three sites: Montrose Arroyo at East Niagara Street (MA2, U.S. Geological Survey site identification number 382802107513301), Montrose Arroyo at 6700 Road (MA3, U.S. Geological Survey site identification number 382711107500501), and Montrose Arroyo at 6750 and Ogden Roads (MA4, U.S. Geological Survey site identification number 382702107493701). A detailed land-use change analysis was also characterized in the MA3 subwatershed.

    Salinity and selenium are naturally occurring and perva-sive in the lower Gunnison River Basin of Colorado, includ-ing the watershed of Montrose Arroyo. Although some of the salinity and selenium loading in the Montrose Arroyo study area is from natural sources, additional loading has resulted from the introduction of intensive irrigation in the water-shed. With increasing land-use change and the conversion from irrigated agricultural to urban land, land managers and stakeholders need information about the long-term effects of land-use change on salinity and selenium loading. In response to the need to advance salinity and selenium science, the U.S. Geological Survey, in cooperation with the Bureau of Reclamation, Colorado River Basin Salinity Control Forum, and Colorado River Water Conservation District, developed a study to characterize salinity and selenium loading and how salinity and selenium sources may relate to land-use change in Montrose Arroyo. This report characterizes changes in salinity and selenium loading to Montrose Arroyo from March 1992 to February 2010 and the magnitude of land-use change between unirrigated desert, irrigated agricultural, and urban land-use/land-cover types, and discusses how the respective loads may relate to land-use change. Montrose Arroyo is an approximately 8-square-mile watershed in Montrose County in western Colorado. Salinity and selenium were studied in Montrose Arroyo in a 2001 study as part of a salinity- and selenium-control lateral project. The robust nature of the historical dataset indicated that Montrose Arroyo was a prime watershed for a follow-up study. Two sites from the 2001 study were used to monitor salinity and selenium loads in Montrose Arroyo in the follow-up study. Over the period of 2 water years and respective irrigation seasons (2008-2010), 27 water-quality samples were collected and streamflow measurements were made at the historical sites MA2 and MA4.

    The fossil content of the Vendian to Lower Cambrian Arroyo del Soldado Group of the Nico Perez Terrane of Uruguay is analysed.Organic walled microfossils represented by acritarchs, eukariotic algae (sensu lato) and iron bacteria are recognized. An updated list of these microfossils is presented, which were are now reported in the Yerbal and Barriga Negra formations.Events of weutrphic conditions were reconstructed. The occurrence of Cloudina riemkeae, the earliest known metazoanwith a mineralized skeleton is communicated for the first time in Uruguay. The organic walled microfossils as well as Cloudina riemkeae are indicative of a Vendian age, whereas the trace fossils of the uppermost unit(Cerro Victoria) suggest the Early Cambrian. This would imply that the Group contains the Precambrian-Cambrian boundary. The Arroyo del Soldado Group is correlated with the Jacadiga and Corunba Groups (Brasil) and the Nama Group (Namibia).

  9. Effects of Storm Events on Bacteria and Nutrients in the Bayou Chico Watershed

    Levels of Escherichia coli and abiotic nutrients often increase in response to storm events due to urban runoff. The urban setting, aging septic systems, and ample pet waste (predominant sources of bacterial and nutrient contamination) that surround Bayou Chico, provide abundant possibilities for contamination. E. coli is a gram-negative, rod shaped bacteria commonly found in the intestines of animals; while some strains are harmless, others produce dangerous toxins that can cause side effects and sometimes death. Along with E. coli, inorganic nutrient concentrations (orthophosphate, nitrate/nitrite, and ammonium) are key indicators of water quality. Dissolved nutrients promote the growth of primary producers and excessive amounts lead to algal blooms, often reducing biodiversity. Four sites were sampled weekly in June and July 2017; during which, June had the highest rainfall in comparison to the past three years; these four sites represented three different sub-watersheds of the Bayou Chico Watershed, with differing land-use at each site. Historical nutrient and bacterial data from the Bream Fishermen Association was also compared and examined to determine long term trends and obtain a more in-depth understanding of the dynamics of water quality in th urban setting. E. coli levels were universally high (ranging from 98 to 12,997 MPN/100mL) for all sites and did not show observable correlations to rainfall; possibly influenced by the systemic and anomalous heavy precipitation during most of the summer study period. Nitrate was detected at levels between 2.5 and 154.0 µM, while ammonium levels ranged from 0 to 16.1 µM. Three of four stations showed extremely elevated dissolved inorganic nitrogen and ammonium while one station showed low levels of these nutrients. Correlations between these nutrient loads and rainfall, support the hypothesis that runoff into tributary creeks contributes significant inorganic nutrient loads to the Bayou Chico urban estuary.

    The untreated, chronic synovial inflammation leads to pannus formation and eventual destruction of the articular cartilage. In cases where medical therapy was unsuccessful, surgical of radiation synovectomy over surgical synovectomy are (1) greater destruction of diseased synovium, (2) reduced Potential for blood clots and infection, (3) no requirement for anesthesia, and (4) less costly and less time consuming. Recently KAERI developed Dy-165 HMA, which was characterized by the absence of iron and a higher concentration of dysprosium. And then more recently KAERI also developed {sup 16H}o-CHICO, which was characterized by relatively longer half-life (26.8 hr), more biological due to organic nature of chitosan, more even spatial distribution due to colloidal solution, and more absorbable to synovium than Dy-165 HMA. These long-term follow-up results indicate that the {sup 166}Ho-CHICO is an effective and safe agent for radiation synovectomy for knee synovitis in patients with rheumatoid arthritis as well as the other chronic arthritides. But further large scaled and controlled study are required. 16 refs. (Author)

    Full Text Available Los macroinvertebrados acuáticos responden a las características de su ambiente reflejando las alteraciones en el mismo. Por ello, son frecuentemente utilizados como indicadores biológicos en estudios de calidad de agua y monitoreo ambiental. El índice de estado trófico TSI-BI creado para la cuenca del río Santa Lucía, que incluye la cuenca de estudio, permite conocer el estado trófico de los arroyos mediante su composición de macroinvertebrados acuáticos. El objetivo de este trabajo es evaluar el estado trófico de los arroyos de la cuenca del embalse Paso Severino a través de la comunidad de macroinvertebrados mediante el índice TSI-BI. El embalse es utilizado como fuente de agua potable para la zona sur densamente poblada del país. La zona ha tenido un importante desarrollo de la actividad lechera en las últimas décadas. Se seleccionaron 10 subcuencas pertenecientes a arroyos de órdenes 2-4 tomándose muestras estacionales (2009-2010 de macroinvertebrados con red de mano de 500 µm. Se analizaron la abundancia relativa y composición de los macroinvertebrados, estimándose el estado trófico de los arroyos mediante el índice TSI-BI. Todos los arroyos estudiados presentaron niveles altos a muy altos de contaminación orgánica situándose en los rangos eutrófico-hipereutrófico. Los arroyos de mayor estado trófico (hipereutróficos presentaron una comunidad dominada por Hirudinea y Crustacea, mientras que en los de menor nivel trófico se observó una mayor abundancia de Ephemeroptera y presencia de Trichoptera. Los altos niveles tróficos de los arroyos indicarían la existencia de impacto por nutrientes, que llevó a cambios en la comunidad de macroinvertebrados hacia el dominio de organismos tolerantes a la contaminación.

    The untreated, chronic synovial inflammation leads to pannus formation and eventual destruction of the articular cartilage. In cases where medical therapy was unsuccessful, surgical or radiation synovectomy is necessary especially in the knee joints. The advantages of radiation synovectomy over surgical synovectomy are (1) greater destruction of diseased synovium, (2) reduced potential for blood clots and infection, (3) no requirement for anesthesia, and (4) less costly and less time consuming. Recently KAERI developed Dy-165 HMA, which was characterized by the absence of iron and a higher concentration of dysprosium. And then more recently KAERI also developed {sup 166}Ho-CHICO, which was characterized by relatively longer half-life(26.8 hr), more biological due to organic nature of chitosan, more even spatial distribution due to colloidal solution and more absorbable to synovium than Dy-165 HMA. We studied to evaluate the efficacy and safety of radiation synovectomy with Dy-165 HMA and {sup 166}Ho-CHICO in chronic rheumatoid synovitis with knee. The present study indicates that the Dy-165 HMA and {sup 166}Ho-CHICO are an effective and safe agent for radiation synovectomy.

  17. Rainfall-Driven Diffusive Hydrograph and Runoff Model for Two Sub-Basins within the Arroyo Colorado in South Texas.

    2017-12-01

    The Arroyo Colorado, located within the Rio Grande Valley of South Texas, has been on the list for the State of Texas's most impaired rivers since the 1990's. Few models for the watershed discharge and contaminates transport have been developed, but all require specialized understanding of modeling and input data which must either be assumed, estimated or which is difficult, time-consuming and expensive to collect. It makes sense to see if a general, simpler `catchment-scale' lumping model would be feasible to model water discharge along the Arroyo. Due to its simplicity and the hypothesized diffusive nature of the drainage in the alluvial floodplain deposits of the Arroyo watershed, the Criss and Winston model was chosen for this study. Hydrographs were characterized, clearly demonstrating that the discharge to the Arroyo is greatly affected by precipitation, and which provided clear rain events for evaluation: 62 rain events over a ten-year time span (2007 - 2017) were selected. Best fit curves using the Criss and Winston lag time were plotted, but better fitting curves were created by modifying the Criss and Winston lag time which improved the fit for the rising limb portion of the hydrograph but had no effect on the receding limb portion of the graph. This model provided some insights into the nature of water transport along the Arroyo within two separate sub-basins: El Fuste and Harlingen. The value for the apparent diffusivity constant "b", a constant which encompasses all diffusive characteristics of the watershed or sub-basins in the watershed (i.e. the lumping constant), was calculated to be 0.85 and 0.93 for El Fuste and Harlingen, respectively, indicating that each sub-basin within the watershed is somewhat unique. Due to the lumping nature of the "b" constant, no specific factor can be attributed to this difference. More research could provide additional insight. It is suggested that water diffusion takes longer in the Harlingen sub-basin (larger "b

    Information on the habitat use and movement patterns of Arroyo Toads (Anaxyrus californicus) is limited. The temporal and spatial characteristics of terrestrial habitat use, especially as it relates to upland use in coastal areas of the species' range, are poorly understood. We present analyses of radiotelemetry data from 40 individual adult toads tracked at a single site in coastal southern California from March through November of 2004. We quantify adult Arroyo Toad habitat use and movements and interpret results in the context of their life history. We show concentrated activity by both male and female toads along stream terraces during and after breeding, and, although our fall sample size is low, the continued presence of adult toads in the floodplain through the late fall. Adult toads used open sandy flats with sparse vegetation. Home-range size and movement frequency varied as a function of body mass. Observed spatial patterns of movement and habitat use both during and outside of the breeding period as well as available climatological data suggest that overwintering of toads in floodplain habitats of near-coastal areas of southern California may be more common than previously considered. If adult toads are not migrating out of the floodplain at the close of the breeding season but instead overwinter on stream terraces in near-coastal areas, then current management practices that assume toad absence from floodplain habitats may be leaving adult toads over-wintering on stream terraces vulnerable to human disturbance during a time of year when Arroyo Toad mortality is potentially highest.

    Arroyo Seco, a perennial drainage in the central Coast Range of California, records a sequence of strath terraces. These terraces preserve an erosional and depositional history, controlled by both climate change and regional tectonics. These deposits have been mapped and correlated on the basis of field investigations, digital terrain analysis, stream gradient profiles, evaluation of published regional soil maps, and satellite imagery. Seven of the strath terraces and associated alluvial fans have been dated by optically stimulated luminescence (OSL) or infrared stimulated luminescence (IRSL). The OSL and IRSL dates on seven of the strath terraces and associated alluvial fans in Arroyo Seco are approximately >120 ka, >65 ka, 51–46 ka, 36–35 ka, 9 ka, and 2–1 ka. These dates generally fall within the range of ages reported from many well-dated marine terraces on the California coast that are formed during sea-level high stands. Tectonic movements, consistently upward, result in a constantly and slowly emerging coastline, however, the regional effects of climate change and resulting eustatic sea-level rises are interpreted as the driving mechanism for erosion and aggradation in Arroyo Seco.

    Sedimentary facies from the Candeleros Formation (Rio Limay Subgroup), cropping out at the El Escondido creek, at the Ezequiel Ramos Mexia dam, are analyzed and interpreted in this paper. A sedimentological detailed section was measured to get the main goal of this paper which is the sedimentary paleoenvironment. The outcroppings were pictured and a section was measured, geometries and espacial relation between them were analyzed. Eight lithofacies were identified which are: coarse sandstone facies (Se), sandstones (Sm, St, Sp, Sh t Sr), siltstones and shales (Fl and Fr). These lithofacies were agrupated into eight facies associations (FA). AFA constitutes the registration of multiepisodic events of sheet floods; AFB, C and D are product of the depositation in a braided channel belt, AFE represents units of lateral accretion, AFF is assigned deposits of crevasse splay and AFG and H are assigned to plain of flood. The distribution of these associations in the column defines an terminal fan paleoenvironment where is represented of base to top: distal (AFA, B and G) and proximal area (AFD and G) of the distributary plain; zone of feeding of the system (AFC, And, F and G), media-proximal distributary plain (AFD and F), proximal distributary plain (AFC, And, F and G); and flood basin (AFF, G and H) [es

  5. Aggradation of Leveed Channels and Their Flood Plains in Arroyo Bottoms

    Vincent, K. R.

    2005-12-01

    Many arroyos that formed by incision more than a century ago in the southwestern United States are currently filling with sediment. This reversal of processes is important because it causes changes in riparian ecology, erosion hazards, ground water recharge, and sediment supply to downstream. Along the Rio Puerco and Chaco Wash in New Mexico, we examined the geometry and facies of channel and floodplain stratigraphy exposed in trenches, used high-resolution dating of the sedimentary beds, and used photographs and other historical evidence to investigate the processes of aggradation in naturally leveed channels within arroyos. Prior to the onset of aggradation, the streambeds were composed of sand and had low relief, and arroyo walls retreated rapidly due to stream undermining. Aggradation began with the formation of sand levees at the margins of the streambeds, followed by formation of newer levees increasingly closer to the thalweg. These levees coincide with rows of woody shrubs (tamarisk and willow), plants that germinated in moist sand along the high-water marks of moderate flows, and survived because subsequent periods lacked flows large enough to remove them. Flow entering a row of woody shrubs decelerates, promoting deposition of suspended sand. Stream flows in this setting are always turbid but do not have the rheology of debris flows. The rows of shrubs probably are a requirement for initial formation of sand levees on low relief streambeds in this setting. As new levees formed closer to the thalweg the channel effectively narrowed, and smaller discharges overtopped the levees adjacent to the channel. Those closer levees accumulated sand most rapidly, leaving the suspended sand concentration depleted by the time water reached more distant ones. All levees aggraded vertically. As the main channel narrowed it acquired a roughly trapezoidal-shape (Top Width/Depth ~ 9 to 5) with banks inclined close to the angle of repose. In addition, sediment deposited on

    Full Text Available Acidic waters of the «Arroyo del Val» stream are naturally generated by oxidation of sulfide minerals dispersed in the sedimentary materials of the drainage basin. Mixing of this acidic stream with neutral-alkaline tributaries yields spectacular iron and aluminium rich flocculants that precipitate at the confluences. Previous analysis of rare earth element (REE concentrations of sorne 0.1 I-tm-filtered water samples and colloids are shown. The shale-normalized REE patterns of acidic waters show significant HREE enrichments in terms of Lun/Lan (≈ 2 and they are tipically enriched in the intermediate REEs (IREEs, Eu-Gd-Tb. So, in detail, these patterns are characterized by HREE enrichments between La and Gd and HREE depletions between Gd and Lu. The REE contents of two colloid samples are enriched by 103_104 relative to acidic waterso Different REE patterns were found in these colloids, sampled at differents distances from head of Arroyo del Val stream. Colloid sampled between the acidic waters analysed (CV-l shows a very similar REE pattern to those of the waters. The REE composition normalized to shale of second colloid sample (CV-2, collected down stream, has a flatter profile although it is still slightly convexo Significant REE removal (about 50 % caused by colloid coagulation is observed at the confluence and mixing point of the Arroyo del Val acidic waters with the first alkaline tributary. At this point the CV-l colloid sample shows HREE enrichment relative to acidic waters.El Arroyo del Val (provincia de Zaragoza constituye un curso de aguas ácidas de origen natural, generadas por el lavado de los materiales paleozoicos que atraviesa (Formación Bádenas, ricos en sulfuros metálicos dispersos.

    Engage the UNIFESP Cardiovascular Surgery residents in coronary anastomosis, assess their skills and certify results, using the Arroyo Anastomosis Simulator and UNIFESP surgical models. First to 6th year residents attended a weekly program of technical training in coronary anastomosis, using 4 simulation models: 1. Arroyo simulator; 2. Dummy with a plastic heart; 3. Dummy with a bovine heart; and 4. Dummy with a beating pig heart. The assessment test was comprised of 10 items, using a scale from 1 to 5 points in each of them, creating a global score of 50 points maximum. The technical performance of the candidate showed improvement in all items, especially manual skill and technical progress, critical sense of the work performed, confidence in the procedure and reduction of the time needed to perform the anastomosis after 12 weeks practice. In response to the multiplicity of factors that currently influence the cardiovascular surgeon training, there have been combined efforts to reform the practices of surgical medical training. 1 - The four models of simulators offer a considerable contribution to the field of cardiovascular surgery, improving the skill and dexterity of the surgeon in training. 2 - Residents have shown interest in training and cooperate in the development of innovative procedures for surgical medical training in the art.

    The named Yapeyu paleosurface placed between Yapeyu and del Palacio Members of the Asencio Formations is anlalyzed in outcrops of the Pedro Chico, Gruta del Palacio and Cca. Arroyo Coquimbo localities. Herrein, its morphologic and paleoenvironmental features are considered to attribute an paleosoil origin for this. This paleosurface is indicative of an important break in the sedimentation and contain several indicators of paleoclimatic tropical and humid conditions. Following allostratigraphic schemes, the paleosurface represent the lower contact of the Asencio Formation constituting a new stratigraphic proposal. Finally, taking into account sedimentalogical features the alluvial origin by the conglomerates of del Palacio Member is rejected. (author)

    Full Text Available Diversos estudios han planteado que los privilegios que el denuncio de bosques otorgaba a los mineros habrían provocado el deterioro irreversible del ambiente del Norte Chico. El presente artículo pretende relativizar esta tesis planteando que el paisaje era semiárido antes de la expansión de la minería y proponiendo la hipótesis que la discusión para derogar los denuncios fue un conflicto entre mineros y agricultores por definir la propiedad de los bosques, pero de los que se encontraban más al sur.Several studies had stablished that the privilege that the claim or denounce of forests that have been given to the miners had caused the irreversible damage to the land of the Norte Chico. This article pretends to diminish this thesis, arguing that the lands was semi dry o semi desertic before the expantion of mines suggesting the hipothesis that the argument to stop with the claim was a struggle betwenn the miners and the farmers to define the property of the forets, but the ones further south.

  19. Assessing the Impacts of Climate and Land Use Change on Streamflow and Nutrient Loading in the Arroyo Colorado Watershed in Southern Texas

    Based on results of the Second National Climate Assessment reported in 2009, the U.S. Global Change Research Program projects temperatures in southern Texas will increase 5 to 8° F by the end of the 21st century, with larger changes occurring under scenarios of higher greenhouse gas emissions. Temperature increases in summer are projected to be larger than in winter. Although drier conditions are expected in the region, sea-level rise, extreme rainfall events, and associated storm surges are projected to occur more frequently because of the likely increase in intensity of hurricanes and tropical storms in the Gulf of Mexico. The range of possible responses to climate change is attributable to a combination of characteristics at global, regional, and local scales. The risk of flooding and catastrophic infrastructure damage due to global climate phenomena has been incorporated into local climate adaptation plans for many low-lying areas and communities in the Gulf Coast region of southern Texas. However, because this region is dominated by irrigated agriculture and the population is projected to double by 2050, it is important to examine how climate change will affect water resources and environmental quality. The purpose of this study is to investigate the potential hydrologic and water quality impacts of projected climate change, land use change, and population change scenarios in the headwaters of the Arroyo Colorado. The results of this work will provide content for a web-based, collaborative geospatial decision support system being developed to support environmental management in the Arroyo Colorado Watershed. Presently, land use in the Arroyo Colorado Watershed is more than 50 percent agricultural and almost 25 percent residential with varying levels of urbanization. As a result, flow in the Arroyo Colorado is sustained primarily by discharge from municipal wastewater treatment facilities, irrigation return flows, and urban storm runoff. In this study

    Full Text Available The restoration of the Arroyo (stream de los Quiñones (San Sebastián de los Reyes poses a problem whose solution consists in neutralizing the principal sources of its degradation. These sources are: waste water discharges, an urban solid waste dump, situated in the very bed of the stream, and the intensive aggregate extraction which made the stream itself disappear at various points. This article also deals with the recuperation of the surrounding wood in a natural and landscape-friendly way, which would facilitate the access and the walk along the sides of the stream. This would lead to the clearing of other areas of a high ecological value within this municipality.

    The large estuaries can present long narrow branches called subestuaries or tidal creeks. These types of subsystems are distributed along the Uruguayan coast of the Río de la Plata estuary and are very important as nursery and refuge areas for fish. For the first time, the seasonal composition and abundance of the fish community of the Solís Chico subestuary was studied by using beach and gill nets. Fourteen species, mainly euryhaline (86%) presented a significant representation of juvenile stages. The fish community was dominated by Odontesthes argentinensis, Platanichthys platana, Mugil liza, Brevoortia aurea, Micropogonias furnieri and Paralichthys orbignyanus, similar to adjacent subestuaries. While Micropogonias furnieri and B. aurea were the most abundant species, some other species were rarely caught. A seasonal variation of the fish assemblage abundance was detected, with higher values in autumn showing a positive correlation with temperature. Species that complete their life cycle in the Río de la Plata estuary, some of which are relevant to fisheries (64% of the analyzed species) were captured in the Solís Chico subestuary. The importance of this environment as a transitional system for some estuarine fish species is advised.

    The Norte Chico region on the coast of Peru north of Lima consists of four adjacent river valleys--Huaura, Supe, Pativilca and Fortaleza--in which archaeologists have been aware of a number of apparently early sites for more than 40 years (refs 1- 3). To clarify the early chronology in this region, we undertook fieldwork in 2002 and 2003 to determine the dates of occupation of sites in the Fortaleza and Pativilca valleys. Here we present 95 new radiocarbon dates from a sample of 13 of more than 20 large, early sites. These sites share certain basic characteristics, including large-scale monumental architecture, extensive residential architecture and a lack of ceramics. The 95 new dates confirm the emergence and development of a major cultural complex in this region during the Late Archaic period between 3000 and 1800 calibrated calendar years bc. The results help to redefine a broader understanding of the respective roles of agricultural and fishing economies in the beginnings of civilization in South America.

    Full Text Available La regulación de ríos y arroyos mediante diques modifica parámetros que influyen directamente sobre la biota. En la cuenca endorreica Achiras-del Gato ha finalizado recientemente la construcción de una presa de mediana envergadura que alterará las características limnológicas del sistema y la estructura de las comunidades bentónicas. Este estudio aporta los primeros registros del macrobentos de este sistema lótico y analiza la variación espacio-temporal de la estructura de la comunidad en tramos pedemontanos del arroyo Achiras. Durante un año, antes de la construcción de la presa, se colectaron muestras de zoobentos y se registraron variables abióticas en correderas y rabiones de dos sitios del arroyo, uno situado río arriba del área del dique y otro aguas abajo de la misma. Para cada sitio, hábitat y estación del año se determinó abundancia, frecuencia, riqueza taxonómica, Índice de Shannon y equidad, y se analizaron mediante ANOVA de una y tres vías. Los atributos de las comunidades de referencia se complementaron con la determinación de taxa exclusivos e indicadores y detectores ecológicos. En el primer sitio se registraron 73 taxa, Simulium fue más abundante y Leptohyphes eximius Eaton, 1882, más frecuente. En el segundo se hallaron 75 taxa, Caenis fue más abundante y Cricotopus sp. 3 más frecuente. La abundancia y la riqueza fueron significativamente mayores en primavera, y la diversidad en rabiones de invierno. Se determinó que los atributos de la comunidad estuvieron afectados por la época de muestreo. El arroyo Achiras posee un régimen hídrico freático-pluvial, con caudales bajos en invierno y altos en verano, por lo que se esperan cambios en la biota nativa y la integridad del sistema en respuesta a la reducción de la variabilidad hidráulica cuando el funcionamiento de la presa altere el caudal natural.

The work was carried out taking into account one particular Justice of the Peace Office, the one located at Tres Arroyos County. On the one hand, the profile of the subjects who acted as Justices of the Peace is reconstructed so as to understand the logics guiding the appointment thereof. For this, research work is done in order to reconstruct their biographies associated to the different terms of office and local institutionalization. Then, two grouping modes that served as a relational basis for local individuals and that allowed to complete the explanation developed from individual biographies are identified: an initiation ritual-type network, as it was the case of masonry, and a local conservatism network, managed by local and powerful ranch and farm owners. Finally, it is observed if these networks had an influence on local justice administration. The sources used are several local commemorative albums, census data, local newspapers, criminal records brought before the Justice of the Peace in Tres Arroyos, the Copybook of the Justice of the Peace Office, and the Book of Records of Tres Arroyos Hiram Lodge.Este artículo se propone analizar la forma en que se implantó la Justicia de Paz en el interior de la provincia de Buenos Aires entre 1865 y 1910, a través del estudio de los sujetos que desempeñaron esa función y los entramados políticos en los que participaron.

    Detailed documentation of geomorphic changes in the landscape of more than a few years is rarely possible. Channel cross sections, channel profiles, sediment deposition behind dams, and hillslope-erosion plots, originally benchmarked within several watersheds outside Santa Fe, New Mexico, in the 1950’s and 1960’s, for a 1966 report that documented processes and rates of arid-region sediment production and deposition, were resurveyed in the mid-1990’s. Many of the original study sites were relocated and surveyed in the mid-1990’s to determine subsequent channel and hillslope changes and to determine whether trends of channel and hillslope aggradation and degradation that were evident in the 1950’s and 1960’s have continued. In general, the net change in channel geometry has been small over the last 30–40 years. The average change in cross-sectional area of 32 resurveyed cross sections was erosion of 0.27 square meter, which equates to a 4-percent increase in cross-sectional area. The average net change in thalweg elevation for 51 resurveyed cross sections was degradation of 0.04 meter. Unpublished data (1964–68) from the scour chains showed that 371 chains had an average scour of 0.14 ± 0.14 meter and that 372 chains showed an average fill of 0.13 + 0.11 meter. Scour, found in the original study (1958–64) to be proportional to the square root of discharge, was confirmed with the addition of unpublished data (1964–68). The observed channel changes have no consistent trend, compared either to results observed in the original 1966 study or to distance from the watershed divide. The conclusion drawn in the original study was that most channels were aggrading; the resurvey showed that aggradation did not continue.An increase in housing and population in the Arroyo de los Frijoles watershed since the 1950’s has led to more roads. Channel degradation is most noticeable at road crossings. The greatest degradation of the main channel Arroyo de los

    Full Text Available Special geochemical characters of the Arroyo del Val drainage basin allow to study different aspects related to REE behaviour. The hydrologic system contains a main stream (Arroyo del Val of acidic waters naturally generated (sulfate rich solutions, with high levels of Al, Fe and heavy metals, and with pH values between 3 and 4.5 and several calcium bicarbonate (sulfate tributaries (with pH values as high as 7.5, measurable alkalinity and striking phosphate concentrations. Mixing of the acidic stream with neutral tributaries yields spectacular sulfate-iron-aluminum rich flocculants that precipitate at the confluences, along the principal stream. The concentration of REEs was measured for acidic water samples col1ected along the headwaters zone of the Arroyo del Val stream and for neutral water samples fram two tributaries. The REE content of acidic waters are enriched by 102 relative to neutral ones and the shale-normalized REE patterns for these acidic freshwaters are enriched in the inter• mediate REEs (IREE, Eu-Tb. Speciation calculations were performed on both water groups. Dominant forms of REEs in the acidic waters include free metal species (Ln3+ ≈ 35% and mainly sulfate complexes ((LnSO+4 ≈ 60% and minor Ln(SO4-2 ≈ 5%. REE sulfate complexation don't fractionate the REEs in solution because there is not an appreciable variation in REE sulfate complexation constants across the lanthanide serie. So, REE convex patterns in these acidic waters must be related to interaction of the acid waters with clay minerals and oxyhydroxide coatings in the paleozoic materials of drainage basin and/or with the col1oid pool of those waters. In the neutral freshwaters of tributaries dissolved REEs are complexed with carbonate and phosphate ions. REE carbonate and phosphate complexation constants across the lanthanide serie increase by several orders of magnitude from La to Lu. And so, phosphate and carbonate complexes account for 80

    The study area includes the basin of the Feliciano stream (Arroyo Feliciano) which increasing water resources are affected by the agriculturization rise and the change of soil usage. The 8.199,4 km{sup 2} basin is undergoing a sudden change in the soil usage that goes from an extensive cattle production to intensive rice soybean usage. It has an urban population of approximately 11,600 inhabitants and there are a low number of rural settlers. It is unknown if there is pollution produced by agricultural activity. The objective of this paper is to estimate the pollution vulnerability of the aquifers used for supplying water for human consumption to the towns within the basin; irrigation and watered of animals, fundamentally cattle. There are two internationally standard-considered methods that have been used, known as DRASTIC and GOD, in order to establish the capacity of attenuation of pollutants for elimination, delay and dilution, for agrochemical and fertilizers set in the surface. The outcomes of the application of both methodologies indicate that there is high vulnerability to pollution areas which are in the surroundings of the minor riverbeds and the main course of the Feliciano stream, where the depth to the aquifers is minimal. In the rest of the basin the effect that offers the thickness of the silts and clay of the Hernandarias formation, operates protecting the aquifer. (Author) 12 refs.

    Full Text Available Este artigo propõe uma abordagem acerca da produtividade literária e da polifonia na poética brasileira contemporânea a partir de autores como Chico Alvim e Carlos Nejar. Pretendemos demonstrar que processos de criação configuram as obras destes poetas que têm em comum a característica do ato de deixar falar: de conferir ou imprimir vozes às suas criações num processo de ânima. Chico Alvim e Carlos Nejar manejam o discurso fora da ordenação ou da hegemonia. Inscrevem-no na expressão da pluralidade por meio de um movimento ou jogo dinâmico; do processo contínuo e não de um sistema operante e determinante. Em seus poemas estão inscritas a dramatis personae, responsável pelo trânsito entre o olhar e o deixar falar, em direção ao leitor.

    Full Text Available Las producciones teatrales breves surgidas entre 1890 y 1940 forman parte del sistema denominado “género chico criollo”, que presenta particularidades en cuanto a temáticas, personajes, espacios representados y conflictos que lo diferencian del “teatro por secciones o teatro por horas” español. En el Río de la Plata, estas piezas denominadas genéricamente “sainetes” fueron compuestas por destacados dramaturgos de ambas orillas, para un público mayoritariamente inmigrante, con la finalidad de brindarle un entretenimiento acorde con su horizonte de expectativas y favorecer el entendimiento de una cultura y un país desconocidos. La numerosa colectividad gallega radicada en el ámbito rioplatense, cuya impronta y aportes impactaron en la comunidad receptora en un momento estructuralmente significante para la consolidación de la identidad argentina, tuvo destacada presencia en los sainetes; en ellos es posible rastrear una imagen estereotípica de doble valencia: aspectos negativos –fuerza ‘bruta’, avaricia, incultura, terquedad y mal humor– y aspectos positivos –lealtad, honradez, bondad, generosidad, responsabilidad para con los deberes familiares y laboriosidad–. El presente trabajo analiza las representaciones del colectivo gallego en lo referido a la transmisión de valores, la conservación de raíces culturales, principios éticos y el deseo de ascenso social.

    Full Text Available Chironomidae es una de las familias más abundantes y diversas en los ecosistemas de agua dulce, sin embargo su complejidad sistemática ha sido motivo de su escaso desarrollo en muchos estudios limnológicos. El objetivo de este estudio fue analizar los ensambles de Chironomidae bentónicos y derivantes de un arroyo serrano de la región central de Argentina evaluando abundancia, diversidad y composición de especies en diferentes hábitats fluviales y distintas estaciones del año. Se tomaron muestras cuantitativas de bentos y deriva en el arroyo Achiras (Córdoba, Argentina en hábitats de rabión y corredera, y se registraron variables ambientales en las cuatro estaciones del año, entre 2007 y 2008. Se registró un total de 25 taxones pertenecientes a cuatro subfamilias. Los quironómidos bentónicos constituyeron el 19% de la comunidad de macroinvertebrados, mientras que en deriva representaron el 33%. En el bentos dominó Thienemannimyia sp. y en la deriva, Corynoneura sp. De acuerdo con los resultados de ANOVAs de dos vías, los mayores valores de riqueza taxonómica y densidad bentónica se registraron en el periodo de aguas bajas (otoño e invierno y la diversidad de quirónomidos bentónicos fue mayor en rabión. Por el contrario, para el ensamble de derivantes sólo la equitatividad fue diferente entre hábitats y entre estaciones. El análisis TWINSPAN mostró una separación espacio-temporal de las muestras de bentos, mientras que las muestras de deriva se segregaron sólo temporalmente lo que sugiere que el transporte aguas abajo de los invertebrados homogeniza la variación espacial observada en el bentos. La densidad de bentos y deriva varió de manera similar a través de las estaciones del año y el coeficiente de Jaccard presentó un alto índice de similitud entre bentos y deriva (86%. Este trabajo posibilitó conocer la dinámica temporal y espacial de los quironómidos bentónicos y derivantes en un arroyo serrano. La

    In July 1974 ENUSA (the National Uranium Company) started mining operations in the FE-1 deposit in the municipal district of Saelices el Chico, Salamanca province. This is a deposit of the Stockwork type and is embedded in Cambrian shales of a distinct degree of metamorphism. The primary mineralization is found filling fissures and fractures of only slight longitudinal development. The secondary minerals were deposited in the zones affected by the hydrostatic level. The investigation of the deposit was carried out by the Spanish Nuclear Energy Board (JEN). In its final phases it consisted of a control drilling campaign and a wagon-drill campaign. The deposit was evaluated by the zone-of-influence method in accordance with the control drillings and the wagon drillings. The overall rate of production was 1,200,000 t per annum, of which 200,000 t were ore with a U 2 O 8 content of 0.08%. The output of the processing plant was 130 t U 3 O 8 . In 1976 ENUSA undertook a mining project of much greater scope in consequence of the decision to expand the ore processing plant (objective of the Quercus project). The annual output of the plant in question will be 600 t U 3 O 8 . For this the production of ore will be increased to 825,000 t/a (average grade 0.075%) and the total amount removed will be 9 million tonnes per annum. Account is taken of the whole of the FE deposit, which includes FE-1 and FE-3 and their respective extensions. The evaluation of the deposit was made both on the basis of the results of the control- and wagon-drillings and by the Kriging statistical method. (author)

    In order to provide long-term storage of diverted surface water from the Rio Grande as part of the Aamodt water rights settlement, managed aquifer recharge by surface infiltration in Pojoaque River Basin arroyos was proposed as an option. The initial hydrogeologic and geochemical characterization of two arroyos located within the Pojoaque River Basin was performed in 2014 and 2015 in cooperation with the Bureau of Reclamation to evaluate the potential suitability of these two arroyos as sites for managed aquifer recharge through surface infiltration.The selected reaches were high-gradient (average 3.0–3.5 percent) braided channels filled with unconsolidated sand and gravel-sized deposits that were generally 30–50 feet thick. Saturation was not observed in the unconsolidated channel sands in four subsurface borings but was found at 7–60 feet below the contact between the unconsolidated channel sands and the bedrock. The poorly to well-cemented alluvial deposits that make up the bedrock underlying the unconsolidated channel material is the Tesuque Formation. The individual beds of the Tesuque Formation are reported to be highly heterogeneous and anisotropic, and the bedrock at the site was observed to have variable moisture and large changes in lithology. Surface electrical-resistivity geophysical survey methods showed a sharp contrast between the electrically resistive unconsolidated channel sands and the highly conductive bedrock; however, because of the high conductivity, the resistivity methods were not able to image the water table or preferential flow paths (if they existed) in the bedrock.Infiltration rates measured by double-ring and bulk infiltration tests on a variety of channel morphologies in the study reaches were extremely large (9.7–94.5 feet per day), indicating that the channels could potentially accommodate as much as 6.6 cubic feet per second of applied water without generating surface runoff out of the reach; however, the small volume

    Full Text Available Sabe-se que o processo de ocupação econômica, pós-1970, foi extremamente prejudicial ao meio ambiente e às populações tradicionais da região Amazônica, persistindo ainda hoje as imensas dificuldades de reprodução das famílias no interior da floresta. Um dos principais desafios na busca de um Desenvolvimento Sustentável é a viabilização do desempenho econômico das unidades produtivas, a partir dos produtos florestais não madeireiros (PFNM, e, conseqüentemente, da reprodução social dessa população. Objetiva-se no presente estudo propor uma alternativa factível de pagamento pelos serviços ambientais (PSA promovidos pelas comunidades extrativistas, há mais de um século. Para tanto, busca-se, inicialmente, realizar uma avaliação sócio-econômica da produção familiar rural na RESEX Chico Mendes, em Xapuri-AC, no sentido de oferecer uma proposta coerente com as necessidades das famílias estudadas. Utiliza-se para tanto metodologia própria e específica, por intermédios de medidas e indicadores de resultado socioeconômico, avaliando a evolução do desempenho econômico dos últimos nove anos na região. Os resultados indicam a diminuição da geração de renda de produtos oriundos do extrativismo, demonstrando as dificuldades de reprodução desse sistema e das famílias, além de realçar o fortalecimento de atividades predadoras da floresta, como é o caso da pecuária extensiva, realizada ainda de maneira rudimentar. Face aos níveis de reprodução familiar, calcula-se que o valor mínimo necessário para o PSA seria em torno US$ 13/ha, evidenciando um valor necessário e, ao mesmo tempo, mais adequado frente às proposições da literatura corrente, que estima valores para os mesmos serviços em torno de US$ 50/ha.It is known that the process of economical occupation, in the last forty years, it was extremely harmful to the environment and the traditional populations of the Amazon region, still persisting today

    The Arroyo Rojo Zn-Pb-Cu volcanogenic massive sulfide deposit is the main deposit of the Fin del Mundo District in the Fuegian Andes, Argentina. This deposit is hosted by a Middle Jurassic volcanic and volcanoclastic sequence forming the Lemaire Formation. The latter consists, from the base up, of the following: rhyolitic and dacitic porphyritic rocks, ignimbrite, tuff, and flow. It is underlain by a pre-Jurassic basement and overlain by the hyaloclastic andesites of the Yahgán Formation. The Arroyo Rojo consists of stacked lenticular lenses that are associated with disseminated mineralization in both the footwall and the hanging wall. The internal structure of the ore lenses is marked by the occurrence of massive, semi-massive and banded facies, along with stringer and brecciated zones and minor ore disseminations. The mineral assemblage comprises mainly pyrite and sphalerite, with minor amounts of galena and chalcopyrite and rare pyrrhotite, arsenopyrite, tetrahedrite and bournonite. The ores and the volcanic host rocks have metamorphosed to greenschist facies and were overprinted by a penetrative tectonic foliation, which led to the development of mylonitic, and cataclastic textures, recrystallization and remobilization. Primary depositional characteristics and regional and hydrothermal alteration patterns were preserved despite deformation and metamorphism. Therefore, primary banding was preserved between facies boundaries. In addition, some remnants of magmatic origin are recognizable in preserved phenocrysts and volcaniclastic phenoclasts. Most of the volcanic and volcaniclastic rocks of the host sequence show a rhyolitic to rhyo-dacitic composition. Regional seafloor alteration, characterized by the presence of clinozoisite, Fe-chlorite and titanite, along with quartz and albite, is partially obliterated by hydrothermal alteration. The hydrothermal alteration is stratabound with the following assemblages, which developed from the base to top: (1) Quartz

    CSU, Chico is a comprehensive university with high expectations for both teaching (4 courses per semester) and scholarly work. In an attempt to introduce faculty to their new positions, a two-day New Faculty Orientation has been offered for the last two decades. In AY 2014-15, in an attempt to improve the first year experience for new faculty, the Office of Faculty Affairs established and assessed a New Faculty Mentoring program. Eight college-based mentors were selected based on recommendations by College Deans who suggested successful teachers and scholars who could provide the social and leadership skills to effectively guide others. Based on a needs-assessment survey new faculty completed during orientation, mentors met with their new faculty cohort at least monthly to discuss campus resources, host workshops and provide other support in areas of time management, work-life balance, teaching pedagogies, discipline-specific internal and external funding resources, student support resources, and the preparation of Review/Retention documents. Mentors were paid a small stipend for their work and met twice each semester to discuss readings on mentoring best practices, their mentoring activities with new faculty and to compare the needs of their mentees. Survey results from 28 of 37 new faculty respondents indicate they valued Review/Retention workshops, mentor reviews of teaching and the opportunity to visit mentor classrooms for examples of good teaching practices. Social events helped establish cohorts, although some mentees indicated that some cohorts were too large. An unforeseen outcome was recognition that mid-year hires need to also be included in new faculty cohort groups. Moving forward, mentors will continue to work with their original mentees for a 2nd year. A new group of mentors will be identified for faculty starting in fall 2015 who will work with smaller first-year faculty cohorts and will coordinate with the first generation mentors for peer support.

    Full Text Available El siguiente trabajo pone en discusión el papel que desempeña la planificación del paisaje fluvial en la mitigación del riesgo hídrico, a través del análisis de un proyecto desarrollado para la Cuenca del Arroyo del Gato, en el marco del conglomerado urbano denominado como Gran La Plata. A nivel mundial las estrategias de mitigación del riesgo de inundaciones han incorporado la mirada paisajística, dejando de lado progresivamente el enfoque basado únicamente en obras defensivas y dando lugar a acciones preventivas que se basan en la consideración de las dinámicas del medio natural y fomentan la sensibilidad hacia los sistemas hídricos. En el caso que se analiza prima aún el enfoque basado en las obras de ingeniería hidráulica, así como un escaso reconocimiento del valor ecológico y paisajístico asociado al curso de agua. Siendo la Cuenca del Arroyo del Gato la más densificada de la región, como también una de las más afectadas por elevados niveles de riesgo hídrico, la planificación del paisaje puede contribuir a las estrategias de mitigación de dicho riesgo. En concreto, se realiza aquí un trabajo de carácter cualitativo, basado en el relevamiento y sistematización de estrategias de mitigación del riesgo asociadas al paisaje, exponiendo su aplicación en un proyecto desarrollado para la Cuenca del Arroyo del Gato y considerando su aplicación a nivel metropolitano. El desarrollo de una estrategia de espacios públicos con diferentes funciones según los distintos sectores de la cuenca, demuestra que es posible asociar planificación del paisaje y mitigación del riesgo, lo que representa un abordaje innovador en una región en la que no existe apreciación del paisaje fluvial, ni integralidad en la gestión del riesgo.

    The last nuclear accident in Fukushima nuclear power plant has increased the necessity for measuring radiation in the environment. Therefore, radiation monitors providing results traceable throughout the country become essential and it is very important to test them under the same environmental conditions. The first intercomparison of natural radioactivity under field conditions was held in Saelices el Chico (Salamanca, Spain) in May 2011, including an exercise on environmental dose rate. This article presents the results achieved by 19 instruments belonging to 12 institutions from 7 different countries. The tested detectors are proportional counters, ionisation chambers, Geiger-Mueller and scintillators measuring dose rate in three stations with reference values from 110 to 1800 nGy h -1 All the results were given in terms of air kerma (nGy h -1 ) and the measurements show agreement within 25 % in all the sites. Evaluation criteria based on accuracy and statistical uncertainty were also carried out and 25 % of participants passed the test in all sites. (authors)

    Full Text Available A morte trágica do ator Domingos Montagner que interpretava o personagem Santo, um dos protagonistas da telenovela Velho Chico (Rede Globo – 2016, criada e escrita por Benedito Ruy Barbosa e dirigida por Luis Fernando Carvalho, a alguns capítulos do final da narrativa, não apenas chocou e colocou em luto o país inteiro como, também, impôs um problema muito grave e concreto à obra. Como manter o personagem que era vivido por Montagner na narrativa? A solução encontrada pela equipe de produção da novela surpreendeu positivamente espectadores e crítica. A câmera até então objetiva e neutra, que assumia um foco ideal através do qual o espectador assiste às cenas de fora, foi substituída por uma câmera subjetiva que assumiu um foco narrativo em primeira pessoa. O espectador foi então retirado do lugar clássico de observador externo, sendo convidado a assumir o foco narrativo do personagem. A técnica, apesar de não usual, não é uma novidade absoluta e já foi usada, por exemplo, em A dama do lago (1947, Viagem alucinante (2009, e no Brasil em: Eros, o deus do amor (1981 e Viajo porque preciso volto porque te amo (2009. A novidade está em realizar esta ousadia formal em uma narrativa popular, de grande audiência, e obter o engajamento imediato do público à técnica. Nesse sentido, propomos analisar este sucesso a partir da ideia de imersão advinda das narrativas em primeira pessoa dos videogames.

    During the 2017 Baja Basins Research Experience for Undergraduates (REU), a DJI Phantom 3 Advanced Quadcopter drone equipped with a GPS-enabled, 12 Megapixel camera was manually flown to collect aerial photographs of several geologic outcrops on the Minera Boléo and Lucifer mines in central Baja California Sur. The strip mine faces, roadcuts, and arroyos exposed Neogene to Quaternary sediments of the Santa Rosalía basin including the basal Cu-Zn-Mn-Co-bearing Miocene Boléo Formation that is actively being mined. It is overlain by Plio-Quaternary marine and non-marine deposits. Photographs were collected with a 70% overlap and processed into geographically-referenced, orthophotomosaics using Agisoft Photoscan. The output models have an adequate resolution for viewing bedding and fault characteristics. Measurements can be made inside the 3D models, making drones a useful tool for studying the geometry of stratigraphic, structural, and geomorphologic features. The studied sites included: 1) roadcuts on Mesa Soledad that exposed oblique-slip faults and syntectonically deposited non-marine and marine conglomerates and sandy, fossil-rich Pliocene beach sediment; 2) outcrops of the Boléo Fm in the Texcoco mine area that showed the detailed stratigraphic relationship between ore seams (mantos) and faults; 3) outcrops where sandstone samples were collected for detrital zircon geochronology; 4) strip mine 3120 that exposed faults and folds in the Boléo Formation; and 5) faults in Miocene volcanic rocks in the Arroyo Infierno near the Lucifer mine. This study shows that photogrammetry and modeling of geologic structures exposed in mine and road outcrops can provide useful information for reconstructing basin architecture and clarifying structural evolution of the Santa Rosalia Basin.

    Full Text Available En la actualidad los niños en América Latina enfrentan viejas y nuevas amenazas químicas, físicas, biológicas y sociales que aumentan los riesgos en salud. Por ejemplo, los niños se exponen a numerosas sustancias químicas (contaminantes y ahora además enfrentan a los compuestos de la nanotecnología; se exponen a las radiaciones solares y electromagnéticas junto al incremento en la temperatura dado por la nueva crisis climática; asimismo, mantienen su exposición a la contaminación biológica presente sobre todo en el agua no potable pero ya enfrentan el riesgo de los organismos transgénicos. Finalmente, la violencia familiar o social representa un factor de riesgo para la seguridad humana y los niños son un sector de la población particularmente vulnerable a ella. Para enfrentar estas amenazas nuestro grupo ha creado una propuesta de trabajo denominada CHICOS que incluye el trabajo bajo aspectos Comunitarios, Hospitalarios, de Investigación, con énfasis en la Capacitación, la Orientación a la comunidad y la Seguridad humana. Con esta estructura pueden generarse Programas de Intervención Basados en Evidencia (PIBE que necesariamente deben ser multidisciplinarios a fin de atender amenazas de tan distinto origen. El fin último es reproducir la estrategia para que paulatinamente vayan estableciéndose grupos de salud ambiental infantil en América Latina.In Latin America children today are facing new and old chemical, physical, biological and social threats. They are exposed to chemical pollutants, to solar and electromagnetic radiations, to biological contaminants and now to new threats such as: nanotechnological products, an increase in the ambient temperature due to the climate crisis, and to transgenic organisms. Furthermore, violence either within the family or in the society is also a risk factor for which children are a vulnerable population.

    Full Text Available The economic modernization of the Amazon fostered by the Brazilian military government during the 1960s and 1970s was largely realized without taking into consideration the presence of local households which lived from the extraction of forest products (mainly non-timber. When they began to be expulsed, a political resistance, often guided by the Catholic Church, appeared as well as the creation of unions based on traditional identities, especially that of rubber tappers. During the 1980s, these unions made a strategic alliance with the ecologist movement which started to consider traditional populations, whose lifestyle depended on the forest, as allies for the protection of the Amazon rainforest. The movement gained a decisive momentum at the end of the decade by putting forward new proposals of land tenure for traditional populations, grounded on collective land rights. This strategy has been very efficient during the 1990s and 2000s, during which about 1,300,000 km2 of rainforest were set apart and reserved for the use of “traditional communities” under a variety of legal status. But it has also led to mix under the same “collective” etiquette and principles a number of different ways of using and managing land and natural resources. This assumption however should be nuanced by a careful analysis of the resource management systems existing in each case, for they are in general complex and mix varying proportions of individual and collective decisions. The aim of this paper is to explore this question using the example of the Chico Mendes agroextractive settlement (PAE-CM, inhabited by about 100 rubber tapper families and symbolic of the political struggle of traditional populations in the Amazon for being the home of the rubber tapper leader Chico Mendes assassinated in 1988. Applying Ostrom “design principles”, we try to catch what are the local institutional arrangements and to see if they suggest

    Full Text Available La cuenca del arroyo Pescado Castigado se encuentra localizada en el Sureste de la provincia de Buenos Aires, Argentina. La peculiaridad de esta cuenca de llanura radica básicamente en su morfología poco definida, puesto que provoca que la red de drenaje sea muy versátil y dinámica. Esto afecta a la principal actividad económica: la agricultura y la ganadería a través de la cantidad de agua disponible, cantidad de superficie anegada o con erosión hídrica, hidromorfismo y halomorfismo. El área de estudio presenta cuatro unidades hidrográficas, la primera se caracteriza porque la escorrentía es laminar, la segunda presenta sistemas anárquicos de disipación o derrames areales, la tercera es un sistema mixto lineal y areal y la cuarta es un área poco inundable y anegable que presenta problemas de salinización. El objetivo de este trabajo es analizar los rasgos geomorfológicos de la cuenca que pueden estar asociados al funcionamiento de la escorrentía en estas cuatro unidades.

    The U.S. Geological Survey, in cooperation with the U.S. Soil Conservation Service, began an investigation of sedimentation of Bernalillo Floodwater Retarding Reservoir No. 1 (Piedra Lisa Arroyo) near Bernalillo, New Mexico in 1956. This investigation was part of a nationwide investigation of the trap efficiency of detention reservoirs. Reservoirs No. 1 is normally a dry reservoir and runoff from the 10.6 sq km drainage area generally occurs from high-intensity summer thundershowers. The mesa area of the drainage basin was treated to prevent erosion and gullying and to retard rapid runoff of rainfall. The land treatment consisted of pits, terraces, seeding, and restricted grazing. The total outflow recorded for the period of record (July 19, 1956 to June 30, 1974) was 133 acre-feet, yielding 1 ,439 tons of sediment. Over 99 percent of the coarse sediments and a high percentage of the silts and clays were deposited in the reservoir before reaching the outflow pipe. The determined trap efficiency of Reservoir No. 1 was 96 percent for the period of record. (Woordard-USGS)

    2012-08-01

    Full Text Available This paper discusses the short story ‘El arroyo de la Llorona’ by female Mexican-American writer Sandra Cisneros. In it the main character, Cleófilas, is subject to social, emotional and economic dependence on her husband, according to the cultural constructs on female identity that are still relevant in Latin-American patriarchal societies. Due to her circumstances of complete marginalisation and domestic violence, Cleófilas chooses to avoid reality, and this avoidance not only costs her mental well-being,but also annuls her will to make changes to her suffocating life. Oppressed by a patriarchal system,Cleófilas develops an unusual interest in the Llorona legend and, through the remembrance of this myth, these two female figures become symbols of resistance and liberation. In the story, the Llorona ceases to be the denigrated woman tradition has always made her out to be, and becomes the image of a contemporary heroine capable of challenging radical patriarchal norms.

  6. Ecuadorian honey types described by Kichwa community in Rio Chico, Pastaza province, Ecuador using Free-Choice Profiling

    Patricia Vit

    Full Text Available Abstract Pastaza is the largest and least populated province in Ecuador, with seven native indigenous nationalities. The Kichwas from the Rio Chico community live near to the capital city Puyo, are recognized for their knowledge on stingless honey bees. From the 400 species of Neotropical Meliponini that make honey in cerumen pots, almost 100 thrive in Southern Ecuador, and confer such biodiversity to pot-honey. In this study sensory characteristics of Ecuadorian false and genuine honeys with diverse entomological origin: Apis mellifera – light amber and amber, Geotrigona leucogastra, Melipona grandis and Scaptotrigona sp. (S. ederi np Schwarz were investigated with Kichwa assessors (four female and four male, aged 18–62 years old. The panel was asked to taste and to identify sensory attributes of honey (appearance, taste, smell, aroma, mouthfeel, other tactile sensations, and to score their intensities in 10 cm unstructured line scales anchored with the words weak and strong, using the Free-Choice Profile methodology The Generalized Procrustes Analysis was used on the data. The first and second dimensions accounted for by 61.1% of the variance. In the descriptive sensory evaluation, darker honeys (amber A. mellifera, false and Geotrigona were separated from (light amber A. mellifera, Melipona and Scaptotrigona by the first dimension; whereas thicker honeys (A. mellifera and false were discriminated from thinner honeys (Geotrigona, Melipona and Scaptotrigona by the second dimension. The assessors were able to evaluate and differentiate honey types without previous sensory training. Remarkably, two Kichwa ladies immediately spit out the false honey, in contrast to an acceptance study on 18-honeys, where the false honey was scored among the preferred ones by 58 participants of the First Congress on Apiculture and Meliponiculture in Ecuador. Therefore, results suggest that Ecuadorian native Kichwas keep a sensory legacy of ancestral knowledge

    2007-12-01

    Field trials using Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) and Euxesta stigmatias Loew (Diptera: Ulidiidae) were conducted to evaluate resistance and potential damage interactions between these two primary corn, Zea mays L., pests against Lepidoptera-resistant corn varieties derived from both endogenous and exogenous sources. The endogenous source of resistance was maysin, a C-glycosyl flavone produced in high concentrations in varieties 'Zapalote Chico 2451' and 'Zapalote Chico sh2'. The exogenous resistance source was the Bacillus thuringiensis (Bt)11 gene that expresses Cry1A(b) insecticidal protein found in 'Attribute GSS-0966'. Damage by the two pests was compared among these resistant varieties and the susceptible 'Primetime'. Single-species tests determined that the Zapalote Chico varieties and GSS-0966 effectively reduced S. frugiperda larval damage compared with Primetime. E. stigmatias larval damage was less in the Zapalote Chico varieties than the other varieties in single-species tests. E. stigmatias damage was greater on S. frugiperda-infested versus S. frugiperda-excluded ears. Ears with S. frugiperda damage to husk, silk and kernels had greater E. stigmatias damage than ears with less S. frugiperda damage. Reversed phase high-performance liquid chromatography analysis of nonpollinated corn silk collected from field plots determined that isoorientin, maysin, and apimaysin plus 3'-methoxymaysin concentrations followed the order Zapalote Chico sh2 > Zapalote Chico 2451 > Attribute GSS-0966 = Primetime. Chlorogenic acid concentrations were greatest in Zapalote Chico 2451. The two high maysin Zapalote Chico varieties did as well against fall armyworm as the Bt-enhanced GSS-0966, and they outperformed GSS-0966 against E. stigmatias.

  17. Processes of paleoarroyo aggradation in Kanab Creek, southern Utah

    Science.gov (United States)

    Townsend, K. F.; Rittenour, T. M.

    2015-12-01

    Many alluvial valleys in the southwest United States have experienced repeated periods of arroyo entrenchment and re-aggradation during the Holocene. Previous research suggests arroyo dynamics were regionally synchronous, implying that climate fluctuations are the dominant drivers. However, intrinsic reach- or catchment-specific geomorphic thresholds to entrenchment are also hypothesized to partially control the timing of arroyo processes. This study focuses on the Holocene alluvial history of three entrenched reaches of Kanab Creek, southern Utah, to explore these competing hypotheses. Episodes of prehistoric arroyo cutting and filling are reconstructed by recognition of buttress unconformable contacts in the arroyo-wall stratigraphy and age control derived from optically stimulated luminescence (OSL) and accelerator mass spectrometry (AMS) radiocarbon dating. A combined dataset of 47 OSL and 47 radiocarbon ages is produced, and results indicate at least five periods of aggradation occurred since ~6.0 ka, each interrupted by an episode of arroyo entrenchment. Comparison of this record to recently completed chronologies from arroyo systems in the region indicates near-synchronous arroyo processes over the last ~1.5 ka; however, beyond 1.5 ka correlations are less clear. Broadly contemporaneous alluviation suggests a climatic driver, and comparison to paleoclimate records suggests that arroyo entrenchment events may be driven by transitions from periods of multi-year drought to wetter periods. However, the detailed alluvial chronology indicates that the initiation of aggradation is transient, with each period of paleoarroyo aggradation beginning downstream and propagating upstream, which suggests that potentially regionally synchronous, climate-driven events may not appear as such in the stratigraphic record.

A partir de entrevistas com extrativistas e profissionais de nove instituições governamentais e nãogovernamentais, foi elaborada uma lista com oito usos da terra para a Reserva. Na etapa seguinte, cada participante foi solicitado a ordenar os usos de acordo com as suas prioridades individuais. Por meio do Indicador de Sustentabilidade em Sistemas de Interesse (ISSI foi calculado o grau de convergência entre o interesse (ordenamento de prioridades de cada extrativista e o interesse da comunidade, e entre os extrativistas e as instituições. O manejo de produtos florestais não-madeireiros (PFNMs e o cultivo da roça ainda são os usos da terra preferidos pelos extrativistas 'não-participantes' do PMFC, que atribuíram prioridade mínima para a exploração da madeira. Os extrativistas que já haviam aderido ao PMFC apontaram a exploração da madeira como sua prioridade máxima. Membros das instituições apontaram preferência pelos usos da terra com menor impacto sobre a floresta, posição mais próxima das prioridades dos extrativistas que ainda não haviam aderido ao PMFC. Numa segunda rodada de ordenamento de prioridades do uso da terra, os extrativistas 'participantes' do PMFC mudaram substancialmente o seu primeiro ordenamento, elegendo o manejo de PFNMs e o cultivo da roça como prioridades máximas. Os resultados revelam que a questão da exploração da madeira na Reserva constitui um complexo sistema de interesses e que muitos extrativistas ainda se sentem inseguros em relação às consequências da implementação do projeto, ou seja, que o projeto não estava suficientemente maduro para ser colocado em prática.

    In the Little Missouri Badlands of southwestern North Dakota, the channels of ephemeral streams are incised 2 to 10 m or more into mid-to-late Holocene alluvium. The objectives of this study were to determine the timing and cause(s) of the most recent episodes of fluvial incision and to develop a process-response model that illustrates the formation and evolution of arroyos in this region. The purpose was to distinguish natural from anthropogenic changes to the landscape and to discriminate allogenic from autogenic causes of incision, thereby gaining a greater sense of how steep, relatively small, ephemeral streams evolve. Dendrochronologic and dendrogeomorphic analyses of riparian cottonwoods provide an inexpensive, high-resolution dating method to constrain the time of incision, thereby permitting determination of the cause(s) of incision by evaluating environmental conditions prior to and at the onset of fluvial incision. An examination of seven small (10 to 100 km2) drainage basins indicated ephemeral streams have undergone a four-stage cycle of change within the past 200 years, comprising(i) an initial period of relative geomorphic stability with pedogenesis on the flood plain and low rates of lateral channel migration, (ii) a period of channel incision with subsequent widening of the flood plain through lateral corrasion along middle and upstream reaches, (iii) a concomitant period of aggradation along downstream reaches and, finally, (iv) a period of downstream incision. Dendrochronologic data and dendrogeomorphic relations indicate there have been three distinct periods of fluvial incision in the past 200 years. The first period of incision began in the 1860s and 1870s prior to the onset of European settlement and intensive grazing by domesticated cattle in the area. This period of incision occurred along the middle reaches of all seven of the streams examined and coincided with a severe, protracted drought, suggesting an allogenic cause. The second period

    Full Text Available Durante décadas efluentes poblacionales y minero industriales del carbón han sido descargados en el arroyo San José ubicado en Río Turbio, al sudoeste de la provincia de Santa Cruz (República Argentina, inutilizándolo para cualquier uso. 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.

    In the Hugoton Embayment of southwestern Kansas, St. Louis Limestone reservoirs have relatively low recovery efficiencies, attributed to the heterogeneous nature of the oolitic deposits. This study establishes quantitative relationships between digital well logs and core description data, and applies these relationships in a probabilistic sense to predict lithofacies in 90 uncored wells across the Big Bow and Sand Arroyo Creek fields. In 10 wells, a single hidden-layer neural network based on digital well logs and core described lithofacies of the limestone depositional texture was used to train and establish a non-linear relationship between lithofacies assignments from detailed core descriptions and selected log curves. Neural network models were optimized by selecting six predictor variables and automated cross-validation with neural network parameters and then used to predict lithofacies on the whole data set of the 2023 half-foot intervals from the 10 cored wells with the selected network size of 35 and a damping parameter of 0.01. Predicted lithofacies results compared to actual lithofacies displays absolute accuracies of 70.37-90.82%. Incorporating adjoining lithofacies, within-one lithofacies improves accuracy slightly (93.72%). Digital logs from uncored wells were batch processed to predict lithofacies and probabilities related to each lithofacies at half-foot resolution corresponding to log units. The results were used to construct interpolated cross-sections and useful depositional patterns of St. Louis lithofacies were illustrated, e.g., the concentration of oolitic deposits (including lithofacies 5 and 6) along local highs and the relative dominance of quartz-rich carbonate grainstone (lithofacies 1) in the zones A and B of the St. Louis Limestone. Neural network techniques are applicable to other complex reservoirs, in which facies geometry and distribution are the key factors controlling heterogeneity and distribution of rock properties.

  5. Independent signaling by Drosophila insulin receptor for axon guidance and growth.

    The Drosophila insulin receptor (DInR) regulates a diverse array of biological processes including growth, axon guidance, and sugar homeostasis. Growth regulation by DInR is mediated by Chico, the Drosophila homolog of vertebrate insulin receptor substrate proteins IRS1-4. In contrast, DInR regulation of photoreceptor axon guidance in the developing visual system is mediated by the SH2-SH3 domain adaptor protein Dreadlocks (Dock). In vitro studies by others identified five NPXY motifs, one in the juxtamembrane region and four in the signaling C-terminal tail (C-tail), important for interaction with Chico. Here we used yeast two-hybrid assays to identify regions in the DInR C-tail that interact with Dock. These Dock binding sites were in separate portions of the C-tail from the previously identified Chico binding sites. To test whether these sites are required for growth or axon guidance in whole animals, a panel of DInR proteins, in which the putative Chico and Dock interaction sites had been mutated individually or in combination, were tested for their ability to rescue viability, growth and axon guidance defects of dinr mutant flies. Sites required for viability were identified. Unexpectedly, mutation of both putative Dock binding sites, either individually or in combination, did not lead to defects in photoreceptor axon guidance. Thus, either sites also required for viability are necessary for DInR function in axon guidance and/or there is redundancy built into the DInR/Dock interaction such that Dock is able to interact with multiple regions of DInR. We also found that simultaneous mutation of all five NPXY motifs implicated in Chico interaction drastically decreased growth in both male and female adult flies. These animals resembled chico mutants, supporting the notion that DInR interacts directly with Chico in vivo to control body size. Mutation of these five NPXY motifs did not affect photoreceptor axon guidance, segregating the roles of DInR in the

    Full Text Available Despite being a relatively remote and well conserved area, the sub-Antarctic ecoregion faces pressing global threats from climate change, the ozone hole and introduced species. Its freshwater ecosystems are one of the least studied components of this biome, but they are known to confront a host of invasive taxa including trout and beavers. We set out to understand the basic characterization and dynamics of organic matter processing and decomposition in sub-Antarctic streams under natural forest (NF conditions and in ponds constructed by North American beavers (Castor canadensis (BP. We found these streams have a naturally stable benthic organic matter regime throughout the year with a peak in leaf input from Nothofagus pumilio in autumn. Beaver ponds significantly increased the retention of organic matter and caused significantly higher decomposition rates, probably associated with increased density and biomass of Hyalella spp. As expected, leaf decay rates for N. pumilio, a deciduous species, were higher (NF: -0.0028 day- ± 0.0001 SE; BP: -0.0118 day-1 ± 0.0009 SE than N. betuloides (a broad-leaf evergreen (NF: -0.0018 day-1 ± 0.0005 SE; BP: -0.0040 day-1 ± 0.0003 SE. Overall these results indicate that the naturally low decomposition rates (slower than 89% of a global survey of decay rates for these cold, oligotrophic streams are being modified by introduced beavers to resemble more temperate latitudes.A pesar de ser una zona relativamente remota y bien conservado, la ecorregión subantártica se enfrenta a presiones por amenazas globales por el cambio climático, el agujero de ozono y las especies introducidas.

    This study examines the total Hg contamination in soil and sediments, and the correlation between the total Hg concentration in soil and vegetables in two small scale gold mining areas, São Chico and Creporizinho, in the State of Para, Brazilian Amazon. Total Hg values for soil samples for both study areas are higher than region background values (ca. 0.15 mg/kg). At São Chico, mean values in soils samples are higher than at Creporizinho, but without significant differences at alpha1 in all of São Chico's produce samples, soil-plant parts regression were not significant, and Hg uptake probably occurs through stomata by atmospheric mercury deposition. Wild plants aboveground:root ratios were <1 at both study areas, and soil-plant parts regressions were significant in samples of Creporizinho, suggesting that they function as an excluder. The average total contents of Hg in edible parts of produces were close to FAO/WHO/JECFA PTWI values in São Chico area, and much lower in Creporizinho. However, Hg inorganic small gastrointestinal absorption reduces its adverse health effects.

The experiment used a completely randomized design with 30 replicates. The popcorn genotypes Aelton, Arzm 05 083, Beija-Flor, Colombiana, Composto Chico, Composto Gaúcha, Márcia, Mateus, Ufvm Barão Viçosa, Vanin, and Viviane were evaluated,along with the common maize variety Zapalote Chico. Newly hatched fall armyworm larvae were individually assessed with regard to biological development and consumption of food. The data were subjected to multivariate analyses of variance and genetic divergence among genotypes was evaluated through the clustering methods of Tocher based on generalized Mahalanobis distances and canonical variable analyses. Seven popcorn genotypes, namely, Aelton, Arzm 05 083, Composto Chico, Composto Gaúcha, Márcia, Mateus, and Viviane,were shown to form a cluster (cluster I that had antibiosis as the mechanism of resistance to the pest. Cluster I genotypes and the Zapalote Chico genotype could be used for stacking genes for antibiosis and non-preference resistance.

    Mercury (Hg) contamination is an issue of concern in the Amazon region due to potential health effects associated with Hg exposure in artisanal gold mining areas. The study presents a human health risk assessment associated with Hg vapor inhalation and MeHg-contaminated fish ingestion, as well as Hg determination in urine, blood, and hair, of human populations (about 325 miners and 321 non-miners) from two gold mining areas in the Brazilian Amazon (São Chico and Creporizinho, Pará State). In São Chico and Creporizinho, 73 fish specimens of 13 freshwater species, and 161 specimens of 11 species, were collected for total Hg determination, respectively. The hazard quotient (HQ) is a risk indicator which defines the ratio of the exposure level and the toxicological reference dose and was applied to determine the threat of MeHg exposure. The mean Hg concentrations in fish from São Chico and Creporizinho were 0.83 ± 0.43 and 0.36 ± 0.33 μg/g, respectively. More than 60 and 22 % of fish collected in São Chico and Creporizinho, respectively, were above the Hg limit (0.5 μg/g) recommended by WHO for human consumption. For all sampling sites, HQ resulted from 1.5 to 28.5, except for the reference area. In Creporizinho, the values of HQ are close to 2 for most sites, whereas in São Chico, there is a hot spot of MeHg contamination in fish (A2-São Chico Reservoir) with the highest risk level (HQ = 28) associated with its human consumption. Mean Hg concentrations in urine, blood, and hair samples indicated that the miners group (in São Chico: urine = 17.37 μg/L; blood = 27.74 μg/L; hair = 4.50 μg/g and in Creporizinho: urine = 13.75 μg/L; blood = 25.23 μg/L; hair: 4.58 μg/g) was more exposed to mercury compared to non-miners (in São Chico: urine = 5.73 μg/L; blood = 16.50 μg/L; hair = 3.16 μg/g and in Creporizinho: urine = 3.91 μg/L; blood = 21.04 μg/L, hair = 1.88 μg/g).

    The new holmium-166 chitosan complex ( 166 Ho-CHICO, DW- 166 HC) was prepared by reacting the aqueous acidic solution of chitosan with 166 Ho(NO 3 ) 3 at room temperature with quantitative labelling yield. The progress of the reaction and labelling yield were determined by instant this layer chromatography using silicic acid impregnated glass fiber (ITLC-SA) and developing solvent of MeOH:H 2 O:HAC (49:49:2). The high labelling yield of more than 99% was obtained by reacting chitosan solution (35 mg/4 ml) with 166 Ho(NO 3 ) 3 in which 7 mg of 165 Ho+ 166 Ho were contained as a maximum content. The labelling yield was highly dependent on the pH of the chitosan solution. The optimal labelling could be obtained at pH 2.5∼3.5 The characteristics of 166 Ho-CHICO were similar to those of chitosan, which is biocompatible, biodegradable, non-toxic, soluble and viscous in acidic condition but geltatinuous at pH 6.0 and precipitating in alkaline conditions. 166 Ho-CHICO can be easily prepared by reconstituting freeze-dried chitosan (kit A) with 166 Ho(NO 3 ) 3 solution (kit B) just prior to use. After intrahepatic administration of 166 Ho-CHICO to male rats, the radioactivity concentrations in blood were low and the cumulative urinary and fecal excretion over a period of 0 to 72 hours were 0.53% and 0.54%, respectively. the radioactivity concentration in tissues and the whole-body autoradiography images showed that most of the administered radioactivity was localized at the administered site, and only slight radioactivity was detected from the liver, spleen, lungs, and bones. An autoradiograph after intratumoral administration of 166 Ho-CHICO showed that radioactivity was localized at the administered site of the lesion without distribution to other organs and tissues. A biodistribution study in normal rabbits with 166 Ho-CHICO showed that most of the radioactivities were retained in the knee joint with negligible extra leakage at 72 hours after intra

    Full Text Available Objective: To analyze the factors associated with sexual risk behavior in adolescent girls and boys in order to plan future school health interventions. Methods: A cross-sectional study with two-stage cluster sampling that included 97 schools and 9,340 students aged between 14 and 16 years old was carried out in 2005-2006 in Catalonia (Spain. For the survey, a self-administered paper-based questionnaire was used. The questionnaire contained items on sociodemographic variables, use of addictive substances and mood states, among other items. These variables were tested as risk factors for unsafe sexual behavior. Results: This study included 4,653 boys and 4,687 girls with a mean age of 15 years. A total of 38.7% of students had had sexual relations at least once and 82.3% of boys and 63.0% of girls were engaged in sexual risk behaviors. The prevalence of sexual relations and risk behaviors was generally higher in boys than in girls, independently of the variables analyzed. Boys had more sexual partners (PObjetivos: El objetivo de este estudio es analizar aquellos factores relacionados con conductas sexuales de riesgo en chicos y chicas para poder plantear futuras intervenciones.

    Full Text Available The Drosophila insulin receptor (DInR regulates a diverse array of biological processes including growth, axon guidance, and sugar homeostasis. Growth regulation by DInR is mediated by Chico, the Drosophila homolog of vertebrate insulin-receptor-substrate proteins IRS1-4. In contrast, DInR regulation of photoreceptor axon guidance in the developing visual system is mediated by the SH2-SH3 domain adaptor protein Dreadlocks (Dock. In vitro studies by others identified five NPXY motifs, one in the juxtamembrane region and four in the signaling C-terminal tail (C-tail, important for interaction with Chico. Here we used yeast two-hybrid assays to identify regions in the DInR C-tail that interact with Dock. These Dock-binding sites were in separate portions of the C-tail from the previously identified Chico-binding sites. To test whether these sites are required for growth or axon guidance in whole animals, a panel of DInR proteins, in which the putative Chico and Dock interaction sites had been mutated individually or in combination, were tested for their ability to rescue viability, growth, and axon guidance defects of dinr mutant flies. Sites required for viability were identified. Unexpectedly, mutation of both putative Dock binding sites, either individually or in combination, did not lead to defects in photoreceptor axon guidance. Thus, either sites also required for viability are necessary for DInR function in axon guidance and/or there is redundancy built into the DInR/Dock interaction such that Dock is able to interact with multiple regions of DInR. We also found that simultaneous mutation of all 5 NPXY motifs implicated in Chico interaction drastically decreased growth in both male and female adult flies. Mutation of these 5 NPXY motifs did not affect photoreceptor axon guidance, showing that different sites within DInR control growth and axon guidance.

  12. Conflicting evolutionary patterns due to mitochondrial introgression and multilocus phylogeography of the Patagonian freshwater crab Aegla neuquensis.

    Brian R Barber

    Full Text Available BACKGROUND: Multiple loci and population genetic methods were employed to study the phylogeographic history of the Patagonian freshwater crab Aegla neuquensis (Aeglidae: Decopoda. This taxon occurs in two large river systems in the Patagonian Steppe, from the foothills of the Andes Mountains east to the Atlantic Ocean. METHODOLOGY/PRINCIPAL FINDINGS: A nuclear phylogeny and multilocus nested clade phylogeographic analysis detected a fragmentation event between the Negro and Chico-Chubut river systems. This event occurred approximately 137 thousand years ago. An isolation-with-migration analysis and maximum-likelihood estimates of gene flow showed asymmetrical exchange of genetic material between these two river systems exclusively in their headwaters. We used information theory to determine the best-fit demographic history between these two river systems under an isolation-with-migration model. The best-fit model suggests that the Negro and the ancestral populations have the same effective population sizes; whereas the Chico-Chubut population is smaller and shows that gene flow from the Chico-Chubut into the Negro is four times higher than in the reverse direction. Much of the Chico-Chubut system appears to have only been recently colonized while the Negro populations appear to have been in place for most of the evolutionary history of this taxon. CONCLUSIONS/SIGNIFICANCE: Due to mitochondrial introgression, three nuclear loci provided different phylogeographic resolution than the three mitochondrial genes for an ancient fragmentation event observed in the nuclear phylogeny. However, the mitochondrial locus provided greater resolution on more recent evolutionary events. Our study, therefore, demonstrates the need to include both nuclear and mitochondrial loci for a more complete understanding of evolutionary histories and associated phylogeographic events. Our results suggest that gene flow between these systems, before and after fragmentation

    The mineralogical and chemical studies and the thermodynamic conditions evaluated permit to represent different stability diagrams of the ferromagnesian minerals of the main units of the Marincho Complex, and of the Arroyo Grande granodiorite. The geochemical and thermodynamics characteristics allow to establish different evolutionary models. It suppose that the granodiorite of the main unit and the granodiorites associated with the porphyroblastic hornblendites derive from magmatic differentiation by fractional crystallization. The same process is considered for the granodiorite of Arroyo Grande, although the magma source is different.

The attitudinal factors embrace a group of variables on the image of science, environmental preservation and some aspects of school science and have been analyzed in a sample of students across several ages starting at the fourth grade. The decline mainly affects the attitudes toward school science, while the attitudes towards the image of science or the environmental preservation do not exhibit this deterioration. The time evolution of the students' answers demonstrates the global decrease of attitudes across age and gender: the first grades display the best attitudes, then they significantly decrease as the age increase; moreover boys and girls display different profiles of attitudinal decay across time. The implications of these results for school science education and the limitations of the study are discussed.

  19. Precise Dating of Flood-Plain Stratigraphy Using Changes in Tree-Ring Anatomy Following Burial

    Determination of sediment deposition rates from stratigraphy is typically limited by a scarcity of chronological information. We present a method for precise dating of sedimentary beds based on the change in anatomy of tree rings upon burial. When stems of tamarisk (Tamarix ramosissima)and sandbar willow (Salix exigua) are buried, subsequent annual rings in the buried portions become narrower and vessels within the rings become larger. Observation of these changes can be combined with tree ring counts to determine the year of deposition of sedimentary beds that are at least 10 cm thick. Using a backhoe we dug trenches across the flood plain at three locations along the arroyo of the Rio Puerco, New Mexico. At each cross section we prepared a detailed stratigraphic description and excavated several tamarisks to depths as great as 5 meters. From each excavated tree we cut and sanded 10-50 slabs for tree-ring analysis. We cross-dated slabs within and between plants and used the burial signature in the tree rings to date all sedimentary beds in the stratigraphic profile near each plant. We then used the trench stratigraphy to convert depths of sediment deposition around individual trees to areas of deposition in the cross section. In the lower Rio Puerco introduction of tamarisk in 1926 occurred just prior to the beginning of channel narrowing and arroyo filling. Thus the tamarisks record a process of channel change to which they may have contributed. Aggradation has not been synchronous along the lower arroyo. For example, near Highway 6 and Belen, the flood plain has aggraded more than 2 m since 1970, while there has been little aggradation downstream at Bernardo. Much of the sediment deposition in levies at Highway 6 occurred during a flood in 1988. Future work will document longitudinal variation in the arroyo so that we can convert areas of sediment deposition in cross sections to volumes in the arroyo.

    Sediment erosion and deposition in two sets of paired (treated and untreated) upland drainages in the Torreon Wash watershed, upper Rio Puerco Basin, New Mexico, were examined over a 3 1/2-year period from spring 2009 through fall 2012. The objective was to evaluate the effectiveness of shallow, loose-stone check dams, or “one-rock dams,” as a hillslope gully erosion stabilization and mitigation method, and its potential for retaining upland eroded soils and decreasing delivery of sediment to lower ephemeral stream channels. Two high-resolution topographic surveys, completed at the beginning and end of the study period, were used to assess the effects of the mitigation measures at paired-drainage sites in both Penistaja Arroyo and Papers Wash watersheds, and at six main-stem-channel cross-section clusters along Penistaja Arroyo and Torreon Wash in the Torreon Wash watershed.For both drainage pairs, the treated drainage had greater sediment aggradation near the channel than the untreated drainage. Erosion was the dominant geomorphic process in the untreated Penistaja Arroyo drainage, whereas aggradation was the dominant process in the other three drainages. For the Penistaja Arroyo paired drainages, the treated site showed a 51-percent increase in area aggraded and 67-percent increase in volume aggraded per area analyzed over the untreated site. Both Papers Wash drainages showed net aggradation, but with similar treatment effect, with the treated site showing a 29-percent increase in area aggraded and 60-percent increase in volume aggraded per area analyzed over the untreated site. In the untreated Penistaja Arroyo drainage, the calculated minimum erosion rate was 0.0055 inches per year (in/yr; 0.14 millimeters per year [mm/yr]), whereas the calculated aggradation rates for the three drainages for which aggradation was the dominant geomorphic process were 0.0063 in/yr (0.16 mm/yr) for the Penistaja Arroyo treated drainage, 0.012 in/yr (0.31 mm/yr) for the Papers

    Full Text Available We examined seasonal and diel variation in prey species composition and biomass in the diet of the exotic rainbow trout Oncorhynchus mykiss (Walbaum, 1972. The study was carried out in the upper-forested sections of a low order stream in Andean-Patagonia. We studied the importance of functional feeding groups of aquatic invertebrates and the relative contribution of terrestrial and aquatic prey items in order to assess the pathways connecting terrestrial and aquatic ecosystems along a stream food web. Trout fed on approximately 40 invertebrate species and scrapers were consistently selected, suggesting their increased vulnerability to predation. However in terms of biomass, rainbow trout diet was mostly composed by shredders which emphasized the role of the allochthonous plant detritus pathway in food webs of forested small streams. Trout individuals fed more intensively in spring and summer and during daytime. Terrestrial items constituted a minor proportion of the diet implying that this component did not represent a significant subsidy for this fish population.

    Full Text Available O artigo discute o avanço da fronteira agropecuária para dentro da floresta Amazônica, motivado, em grande parte, pelo aumento do consumo de carne bovina e por sua ineficiência na produção de proteínas. A metodologia constou de levantamento bibliográfico e de dados secundários e de campo no município de Xapuri, Acre, onde o fenômeno da pecuarização é bastante intenso, inclusive na Reserva Extrativista Chico Mendes. Em Xapuri, foram entrevistados diferentes atores sociais sobre a motivação para a introdução da pecuária no município e na reserva Chico Mendes. Resultados indicaram fatores históricos, de mercado econômico e de consumo como os principais propulsores. A redução do consumo de carne e seus derivados poderia diminuir a pressão sobre a floresta Amazônica, bem como políticas de incentivo às atividades extrativas.The article discusses the increased grassification and deforestation of the Amazon Forest, related to cattle breeding and motivated by increased meat consumption and its inefficiency in protein production. Methods consisted of literature review, data collection and fieldwork in the municipality of Xapuri, State of Acre, where the grassification process is very intense, even at the Chico Mendes Extractivist Reserve. In Xapuri, different social actors were interviewed about their reasons to introduce cattle breeding in the municipality and inside the Chico Mendes Reserve. Results indicated historical, economic and consumer market factors as the main causes. The reduction in meat consumption and incentives for extractivist products might reduce pressure on the Amazon forest.

    To overcome many problems caused by external radiation therapy, we have developed a new agent for internal radiation therapy, which is administered directly to the lesions and irradiate β-rays resulting in maximized therapeutic effect and minimized radiation damage to normal tissues or organs to nearby. In the same reasons, we have also developed a new radioactive patch for the treatment of skin cancer using β-emitting radionuclide. We prepared for 166 Ho-chitosan complex ( 166 Ho-CHICO) which is potential radiopharmaceuticals for the treatment of liver cancer, peritoneal cancer metastasized from stomach cancer, ovarian cancer, and rheumatoid arthritis in knee joints. We carried out various experiments such as evaluation of absorbed dosimetry, studies on absorption, distribution, metabolism, and excretion (ADME) and clinical trials with 166 Ho-CHICO. For commercialization of 166 Ho-CHICO, we evaluated its toxicity, efficacy and safety, and then prepared documents for submission to the Mininstry of Health and Welfare to get license as an investigational new drug. 166 Ho-Patch for skin cancer treatment was prepared by neutron irradiation of pre-made non-radioactive 165 Ho-Patch. We evaluated the efficacy and safety of 166 Ho-Patch in the treatment of skin cancer using an animal model and in clinical cases. (author). 49 refs., 15 tabs., 36 figs

    The southern California region, although highly urbanized and densely populated, is also characterized by steep mountain ranges with extensive forests and diverse ecosystems. Growing population pressure in the region has forced continuing development at the urban fringe. The large mountain systems situated on the windward side of the Los Angeles basin experience high atmospheric nitrogen deposition rates from various urban pollutants. Arroyo Seco, a watershed located on the eastern edge of the Los Angeles basin, is no exception to this trend. The present study uses hydrologic and geochemical data to assess current watershed dynamics and ecosystem responses to the impacts of regional urbanization. The Arroyo Seco stream runs through a deeply incised canyon originating in the San Gabriel Mountains and draining into the Los Angeles River. The current riparian habitat, which comprises only 15 percent of the total land cover within the watershed, contains over 705 species of plants and animals. We focused our studies on the upper reaches of the basin (~18 square miles), which remains undeveloped and consists primarily of chaparral and evergreen forests. This portion of the watershed has an average watershed slope of approximately 6 percent and relatively porous soils. However, estimated runoff ratio from the existing USGS gage and local precipitation gages indicates fairly high runoff (discharge/precipitation ratio of 0.29). Weekly stream samples have been collected over a several year period and analyzed for standard geochemical constituents and stable isotopes to assess deposition impacts on ecosystem function and overall watershed behavior. Stable isotopes of water measured in the weekly Arroyo Seco stream samples deviate from the global meteoric water line (GMWL), particularly during summer months. High evaporative rates in the summer may be responsible for the distinct summer pattern and overall deviation from the GMWL of stream isotope values. An

    It is crucial to understand the rate and distribution of groundwater recharge in New Mexico because it not only largely defines a limit for water availability in this semi-arid state, but also is the least understood aspect of the state's water budget. With the goal of estimating groundwater recharge statewide, we are developing the Evapotranspiration and Recharge Model (ETRM), which uses existing spatial datasets to model the daily soil water balance over the state at a resolution of 250 m cell. The input datasets includes PRISM precipitation data, MODIS Normalized Difference Vegetation Index (NDVI), NRCS soils data, state geology data and reference ET estimates produced by Gridded Atmospheric Data downscalinG and Evapotranspiration Tools (GADGET). The current estimated recharge presents diffuse recharge only, not focused recharge as in channels or playas. Direct recharge measurements are challenging and rare, therefore we estimate diffuse recharge using a water balance approach. The ETRM simulated runoff amount was compared with USGS gauged discharge in four selected ephemeral channels: Mogollon Creek, Zuni River, the Rio Puerco above Bernardo, and the Rio Puerco above Arroyo Chico. Result showed that focused recharge is important, and basin characteristics can be linked with watershed hydrological response. As the sparse instruments in NM provide limited help in improving estimation of focused recharge by linking basin characteristics, the Walnut Gulch Experimental Watershed, which is one of the most densely gauged and monitored semiarid rangeland watershed for hydrology research purpose, is now being modeled with ETRM. Higher spatial resolution of field data is expected to enable detailed comparison of model recharge results with measured transmission losses in ephemeral channels. The final ETRM product will establish an algorithm to estimate the groundwater recharge as a water budget component of the entire state of New Mexico. Reference ET estimated by GADGET

    Most recently developed climate scenarios indicate a potential future increase in water stress in the region of Comahue, located in the North-Patagonia, Argentina. This region covers about 140,000 km2 where the Limay River and the Neuquén River converge into the Negro River, constituting the largest integrated basins in Argentina providing various uses of water resources: a) hydropower generation, contributing 15% of the national electricity market; b) fruit-horticultural products for local markets and export; c) human and industrial water supply; d) mining and oil exploitation, including Vaca Muerta, second world largest reserves of shale gas and fourth world largest reserves of shale-oil. The span of multiple jurisdictions and the convergence of various uses of water resources are a challenge for integrated understanding of economically and politically driven resource use activities on the natural system. The impacts of climate change on the system could lead to water resource conflicts between the different political actors and stakeholders. This paper presents the results of a hydrological simulation of the Limay river and Neuquén river basins using WEAP (Water Evaluation and Planning) considering the operation of artificial reservoirs located downstream at a monthly time step. This study aims to support policy makers via integrated tools for water-energy planning under climate uncertainties, and to facilitate the formulation of water policy-related actions for future water stress adaptation. The value of the integrated resource use model is that it can support local policy makers understand the implications of resource use trade-offs under a changing climate: 1) water availability to meet future growing demand for irrigated areas; 2) water supply for hydropower production; 3) increasing demand of water for mining and extraction of unconventional oil; 4) potential resource use conflicts and impacts on vulnerable populations.

    Species distribution models are used for numerous purposes such as predicting changes in species’ ranges and identifying biodiversity hotspots. Although implications of distribution models for conservation are often implicit, few studies use these tools explicitly to inform conservation efforts. Herein, we illustrate how multiple distribution models developed using distinct sets of environmental variables can be integrated to aid in identification sites for use in conservation. We focus on the endangered arroyo toad (Anaxyrus californicus), which relies on open, sandy streams and surrounding floodplains in southern California, USA, and northern Baja California, Mexico. Declines of the species are largely attributed to habitat degradation associated with vegetation encroachment, invasive predators, and altered hydrologic regimes. We had three main goals: 1) develop a model of potential habitat for arroyo toads, based on long-term environmental variables and all available locality data; 2) develop a model of the species’ current habitat by incorporating recent remotely-sensed variables and only using recent locality data; and 3) integrate results of both models to identify sites that may be employed in conservation efforts. We used a machine learning technique, Random Forests, to develop the models, focused on riparian zones in southern California. We identified 14.37% and 10.50% of our study area as potential and current habitat for the arroyo toad, respectively. Generally, inclusion of remotely-sensed variables reduced modeled suitability of sites, thus many areas modeled as potential habitat were not modeled as current habitat. We propose such sites could be made suitable for arroyo toads through active management, increasing current habitat by up to 67.02%. Our general approach can be employed to guide conservation efforts of virtually any species with sufficient data necessary to develop appropriate distribution models.

    Full Text Available Antimony has properties similar to arsenic with some of its compounds toxic to humans. Therefore it is necessary to control the wastes accumulated by anthropogenic activities, such as mining, where it is in tailings to be released to the environment. According to the Environment Protection Agency, the maximum value in sediments is 11.2 mg Sb kg–1 and the Earth’s crust average is 0.2 mg Sb kg–1. In this semiarid area, the drainage basin El Carrizal is impacted with wastes of an abandoned gold mine at the Mining District El Triunfo (MD – ET which have tailings with 17,600 mg kg–1 of antimony. In the main dry river (arroyo, the Sb content is between 0.6 and 122 mg kg–1. This element is transported from the source throughout the fluvial basin to discharge into the Pacific Ocean. In the arroyo mouth we collected one sedimentary core and the sediment from dunes (28.6 – 45.7 and 6.43 – 7.74 mg Sb kg–1. This research concluded the antimony is enriched in this semiarid system, with Normalized Enrichment Factors severely enriched mainly in arroyo sediments close to the MD-ET

    The present article is a circuit through the history of various abandoned lead mines at 40 km away from the city of Madrid. These mineralizations are located at the South Est limit of the Sierra de Guadarrama mountain range in the Center of Spain. The deposits were exploited by test pits and small underground mines since the 16th Century till 1971. These small exploitations have a remarkable interest from a cultural point of view due to them having both a geologic value and historic mining-industrial heritage. Due to their proximity to the capital, these mines and out-crops can be exploited for didactic purposes. (Author)

    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.

    2011-01-01

    Full Text Available En el presente trabajo se describe la percepción del clima motivacional generado por el entrenador y por los compañeros en una muestra de deportistas jóvenes y se analizan las diferencias en función del género así como el efecto de los climas motivacionales en la diversión y el compromiso. 121 deportistas con una media de edad de 14.39 años (DE= .96, 39 chicas y 82 chicos completaron las versiones españolas de los instrumentos de clima motivacional promovido por el entrenador, clima motivacional promovido por los compañeros y compromiso deportivo. Los resultados muestran que las chicas perciben climas motivacionales de implicación a la tarea significativamente más altos y de implicación al ego significativamente más bajos que los chicos tanto en el caso del generado por el entrenador como en el caso de los generados por los compañeros. Las deportistas se divierten significativamente más y están igualmente comprometidas con la práctica deportiva que los chicos. el principal predictor del compromiso es la generación de un clima de implicación a la tarea por parte de entrenadores y compañeros. en consecuencia cabría recomendar que los programas de intervención hagan especial hincapié en la generación de climas motivacionales de implicación a la tarea.

    This report combines and summarizes results for two groundwater-sampling events (October 2012 and October/November 2015) from the Sandia National Laboratories/New Mexico (SNL/NM) Burn Site Groundwater (BSG) Area of Concern (AOC) located in the Lurance Canyon Arroyo southeast of Albuquerque, NM in the Manzanita Mountains. The first phase of groundwater sampling occurred in October 2012 including samples from 19 wells at three separate sites that were analyzed by the Environmental Radiochemistry Laboratory at Lawrence Livermore National Laboratory as part of a nitrate Monitored Natural Attenuation (MNA) evaluation. The three sites (BSG, Technical Area-V, and Tijeras Arroyo) are shown on the regional hydrogeologic map and described in the Sandia Annual Groundwater Monitoring Report. The first phase of groundwater sampling included six monitoring wells at the Burn Site, eight monitoring wells at Technical Area-V, and five monitoring wells at Tijeras Arroyo. Each groundwater sample was analyzed using the two specialized analytical methods, age-dating and denitrification suites. In September 2015, a second phase of groundwater sampling took place at the Burn Site including 10 wells sampled and analyzed by the same two analytical suites. Five of the six wells sampled in 2012 were resampled in 2015. This report summarizes results from two sampling events in order to evaluate evidence for in situ denitrification, the average age of the groundwater, and the extent of recent recharge of the bedrock fracture system beneath the BSG AOC.

    The western cratonic domains in Uruguay are divided into three major units: Piedra Alta Terrane, Valentines Block and Pavas Block. Piedra Alta Terrane lacks of evidence of Neoproterozoic orogenesis (deformation, metamorphism or magmatism). Sarandí del Yi - Arroyo Solís Grande shear zone, separates it from Valentines Block. Valentines Block is separated from Pavas Block by Cueva del Tigre shear zone. Magmatic rocks with different ages, compositions and emplacements occur all over the Piedra Alta Terrane distributed in three metamorphic belts (Arroyo Grande, San José and Montevideo) as well as in the Central Gneissic-Migmatitic Complex (Figure 1). Samples from the Gneissic-Migmatitic complex, late tectonic granitoids and basic rocks associated to the metamorphic belts were analyzed using Rb/Sr, U/Pb, K/Ar and Sm/Nd methodologies. The age ranges obtained for granitoids

    Full Text Available In this paper, the role of central plateaus –dated at ca. 3500 AP– in the peopling of the southern end of America that started at around ca. 13000 AP, is discussed. A revision and updating of the archaeological and paleoclimatic evidences and their absolute chronologies were made. To Mid Holocene, the space that we defined as the periphery of central plateaus –Atlantic coast, Colorado, Limay and Chubut rivers– was conformed. During Late Holocene, the inland sites were characterized by a progresively increase in the density of archaeological remains, with dense occupations towards upper levels or the final settlement stage on the Plateaus. An inland Norpatagonia peopling model is proposed, based on which of the peripheral population loci could provoke exploratory and migratory movements, and paleoenvironmental and social explanations are considered.

    perturbations represents a great challenge. We propose to enhance conservation by exerting a stronger sport fishing pressure on trout in those streamsPara evaluar la distribución y abundancia actual de salmónidos y peces nativos muestreamos 11 lagos grandes y 105 arroyos, cubriendo 13 cuencas principales en el sur de Chile desde 39° a 52°S. En general las truchas (Salmo trutta y Oncorhynchus mykiss representaron más de 60 % de la abundancia total de peces y más de 80 % de la biomasa total, además 40 % de los arroyos muestreados no presentaron peces nativos. Los salmones traídos para acuicultura tales como O. kisutch, Salmo salar, y O. tshawytscha solo estuvieron presentes en lagos que tenían salmonicultura, aun cuando no parecen reproducirse exitosamente en los arroyos afluentes. Pusimos a prueba el efecto del origen de los arroyos (cordillera de los Andes, valle central o cordillera de la Costa sobre la abundancia de las especies y encontramos que la trucha arco iris estuvo más restringida a los arroyos preandinos con mayor descarga, mientras la trucha café se distribuyó ampliamente no respondiendo a otras características o atributos específicos de las cuencas que se midieron. La abundancia relativa de peces nativos fue mayor en los lagos que en los arroyos, en tanto la mayor biodiversidad de peces nativos se encontró en arroyos del valle central. Las especies más comunes fueron Galaxias maculatus, G. platei, Brachygalaxias bullocki, Aplochiton zebra y Basilichthys australis. Arroyos con mayor conductividad, más áreas de pozones, más sedimentos finos y con bajas densidades de trucha café fueron más adecuados para peces nativos. Es así que cuencas con mayor disturbio antropogénico parecen ser refugio para los mismos. Dada la naturaleza descriptiva de nuestro estudio solo podemos presumir los efectos negativos de truchas y salmones sobre los peces nativos, efecto que debiera estar sobreimpuesto a los condicionantes biogeográficos de la distribuci

    Full Text Available A principios del siglo XX, el género sicalíptico, es decir el erotismo y lo picante, comenzó a invadir los proscenios de aquellos coliseos en donde se representaba el género chico. El compositor valenciano Vicente Lleó Balbastre se convirtió en la figura de referencia de esta modalidad teatral; con obras tan insignes como La Corte de Faraón, opereta bíblica estrenada en 1910 en el teatro Eslava de Madrid,a la sazón el templo de la sicalipsis, y de la que se llegaron a realizar setecientas setenta y dos representaciones. Este artículo investiga la incidencia del género sicalíptico en los escenarios teatrales líricos madrileños a través de la biografía del maestro Vicente Lleó, uno de los máximos exponentes del género chico.

    2015-01-01

    Full Text Available El ciberacoso es un fenómeno ampliamente analizado entre adolescentes, sin embargo en España ha sido poco estudiado entre jóvenes y particularmente en sus relaciones de noviazgo. Empleando una metodología cuantitativa este estudio analiza el ciberacoso mediante el teléfono móvil e Internet en las relaciones de noviazgo en una muestra compuesta por 336 estudiantes universitarios. El análisis de resultados indica que un 57,2% declara haber sido victimizado por su pareja mediante el teléfono móvil, y un 27,4% a través de Internet. El porcentaje de chicos victimizados fue mayor que el de las chicas. Un 47,6% declara haber acosado a su pareja a través del teléfono móvil, y un 14% a través de Internet. El porcentaje de chicos que lo ejerció fue superior al de las chicas. Los análisis de regresión muestran la relación entre haber sido victimizado por la pareja a través de uno de estos medios y el ejercicio del ciberacoso hacia la pareja mediante el mismo medio tecnológico. Los efectos de interacción ponen de manifiesto que los chicos victimizados a través del teléfono móvil o de Internet se implican, en mayor medida que las chicas victimizadas, como agresores en este fenómeno. Los resultados sugieren una modernización en los tipos de violencia que experimenta la juventud en sus relaciones de pareja.

    Full Text Available La importancia del control por parte de las mujeres de métodos anticonceptivos y aquellos que previenen la infección de enfermedades de transmisión sexual, especialmente el VIH/SIDA, es un tema que adquiere importancia en el marco del aumento de las mujeres afectadas por la epidemia. El objetivo de este trabajo, un estudio de poblaciones mediante encuestas con muestras probabilísticas transversal, es evaluar el conocimiento y viabilidad de uso del preservativo femenino en jóvenes universitarios utilizando una metodología cuantitativa. La muestra estuvo formada por 225 chicas y 105 chicos. Los resultados muestran que casi la mitad de los sujetos han oído hablar del preservativo femenino, pero el 98,8% nunca lo ha usado. Las variables que predicen la asociación de beneficios asociados al uso del preservativo femenino son, para los chicos, las actitudes frente a la sexualidad y para las chicas la disposición a probarlo y los costes. En cuanto a la disposición a usarlo, las variables más influyentes para los chicos son disposición a hablar con la pareja, la disposición a participar y la utilización de métodos anticonceptivos y, para las chicas, la disposición a recomendar el preservativo femenino y estar de acuerdo en que la mujer lo utilice. Estos resultados adquieren una relevancia especial en las investigaciones centradas en reducir el aumento de embarazos no deseados y casos de VIH/SIDA en la población de mujeres y abren nuevas perspectivas alrededor de esta temática.

    Directory of Open Access Journals (Sweden)

    Lima Neuza Rejane Wille

    2002-01-01

    Full Text Available A diversity of all-female fishes of the genus Poeciliopsis coexists with their sexual ancestor species in streams of western Mexico. All-females are hybrids that depend on the sperm of paternal species to reproduce. Rare-female advantage is one of several hypotheses that attempt to explain how the diversity of all-female biotypes is maintained within the Poeciliopsis reproductive complexes. According to this hypothesis, the uncommon all-female biotype has a mating advantage over the common ones and has been maintained by a dynamic equilibrium process. In the P. monacha reproductive complex at Arroyo de los Platanos the density of two all-female biotypes (P. 2monacha-lucida I and II varies across pools. The objective of this study was to analyse fecundity and mating success of females from this arroyo to test the hypothesis. Female mating success was inversely correlated to their density, supporting this hypothesis.

    Full Text Available Drenajes fluviales efímeros e intermitentes son variables importantes para la comprensión de la evolución de las superficies de aplanamiento en las zonas semiáridas. Sin embargo, actualmente este tema ha sido poco estudiado en la literatura geomorfológica brasileña. En esta investigación exploramos este tema y hemos identificado los diferentes niveles de la superficie de aplanamiento, analizamos la cobertura superficial y las características de los arroyos y analizamos la disección de las formas del terreno. Los resultados mostraron que los diferentes niveles de conservación y disección de la superficie de aplanamiento son respuestas de los procesos que actúan en los arroyos y la formación de los compartimentos geomorfológicos son respuestas directas de los diferentes patrones espaciales de la red de drenaje.

    2014-03-01

    Full Text Available Objective. To evaluate risk factors facilitating the colonization of dwellings by Triatoma dimidiata in the central region of the state of Veracruz. Materials and methods. We applied socioeconomic questionnaires and entomologic surveys in three localities (Chavarrillo, Soyacuautla and Arroyo Agrio in central Veracruz involving 115 households. Results. We found that the main risk factors were the predominance of unplastered walls and particularly those made of light weight aggregate concrete blocks and wood. At Chavarrillo, houses usually have unplastered walls, whereas in Soyocuautla walls are commonly manufactured with wood. In Arroyo Agrio, the phenomenon was seasonal, and bugs were commonly found in the dry season, particularly in relatively new houses, less than 20 years old. Conclusions. These results help to improve the surveillance capacity for this vector and the control strategies to reduce the transmission of Chagas disease in the state of Veracruz and other sites where this species is present.

Se aplicaron tres autoinformes: un cuestionario «ad hoc» sobre datos sociodemográficos y manejo de tecnologías de comunicación; el «Cuestionario de Ciberagresión para Adolescentes» (CYBA, para evaluar con qué frecuencia el adolescente evaluado reconoce haber ejercido diferentes conductas de ciberagresión durante los últimos tres meses; y el «Cuestionario de Cibervictimización para adolescentes» (CYVIC, para evaluar con qué frecuencia el adolescente reconoce haber sido víctima de diferentes tipos de ciberagresión en los últimos tres meses. Los resultados obtenidos muestran una prevalencia muy variable en función del tipo de ciberagresión o cibervictimización analizado. La ciberagresión verbal y la exclusión online son más habituales que la suplantación y la ciberagresión visual. Por lo general, no existen diferencias estadísticamente significativas entre chicos y chicas. En los casos en que existen, la tendencia general es que los chicos son más agresores que las chicas y las chicas más víctimas que los chicos, si bien las diferencias son pequeñas o muy pequeñas. Se discuten las implicaciones de estos resultados para la investigación futura y el tratamiento educativo del problema.

  5. Uranium ore mining in Spain with a focus on the closure and remediation measures in former production facilities

    In early 2000, the uranium ore mining activities in Spain ceased. Since the middle of the last century, Spain had pushed ahead its own production of uranium concentrate with the formation of several companies (ENUSA, J.E.N.). In that period, Spain produced around 6000 t of uranium. With the completion of the operations at Andujar, La Haba and Elephante as well as Quercus at Saelices el Chico, the corporate tasks have shifted from building-up of a strategic uranium reserve to remediation and subsequent use of the locations. The operations have reached different remediation phases. While at Saelices el Chico remediation is still proceeding, the Andujar and La Haba locations are undergoing a monitoring phase as agreed for all former operating facilities. The estimated closure and remediation costs for the three operating facilities described amount to approx. 85 mio. Euro. In all three cases dealt with, however, these limited financial resources have been sufficient to successfully implement a closure and remediation concept that minimizes the risks from the facilities of uranium ore mining and processing with regard to the environment.

    Neuman, L.; Houpis, J.; Anderson, P.

    1991-01-01

    To determine the effects of ozone and acid rain on mature Ponderosa pine trees, Lawrence Livermore National Lab. has collaborated with University of California Berkeley, University of California Davis, California State University Chico, and the US Forest Service at the latter's Chico Tree Improvement Center. Foliar tissue from mature grafted scions of Pinus ponderosa were exposed to two times ambient ozone for ten months and to acid rain (3.0 pH) weekly for 10 weeks using branch exposure chambers. Pigment extracts were analyzed spectrophotometrically for concentrations of chlorophylls a and b, and carotenoid pigments, at 662 nm, 644 nm, and 470 nm, respectively. Pigment concentrations were expressed on a surface area basis. Preliminary results revealed that chlorophyll a showed a downward trend due to the ozone treatment. Acid rain caused no effects on these three pigments, however, chlorophyll b showed an upward trend due to the interaction of ozone and acid rain. The carotenoid pigments showed no changes due to the treatments either singly, or in combination

    RESUMEN: Se han estudiado las alteraciones causadas por hipervitaminosis A en la parótida del hamster, mediante métodos cariométricos y estereológicos. Los ácinos y ductos de la glándula del animal tratado mostraron núcleos más chicos y picnóticos. Estereologicamente se observó que la parótida del animal tratado presenta densidad de volumen más chica para ácinos y ductos estriados, diámetro y espesor de la pared más chicos para ácinos y densidad volumétrica más grande para el estroma conjuntivo. Se sugiere que el exceso de vitamina A puede actuar sobre la parótida de dos maneras: a Directamente sobre el epitelio glandular, provocando las alteraciones estructurales y funcionales; b indirectamente, alterando los niveles de las hormonas responsables por la manutención estructural y funcional normal de las glándulas salivares. PALABRAS-CLAVE: Hipervitaminosis A; parótida; hamster.

  16. Retrowedge-related Carboniferous units and coeval magmatism in the northwestern Neuquén province, Argentina

    The studied Carboniferous units comprise metasedimentary (Guaraco Norte Formation), pyroclastic (Arroyo del Torreón Formation), and sedimentary (Huaraco Formation) rocks that crop out in the northwestern Neuquén province, Argentina. They form part of the basement of the Neuquén Basin and are mostly coeval with the Late Paleozoic accretionary prism complex of the Coastal Cordillera, south-central Chile. U-Pb SHRIMP dating of detrital zircon yielded a maximum depositional age of 374 Ma (Upper Devonian) for the Guaraco Norte Formation and 389 Ma for the Arroyo del Torreón Formation. Detrital magmatic zircon from the Guaraco Norte Formation are grouped into two main populations of Devonian and Ordovician (Famatinian) ages. In the Arroyo del Torreón Formation, zircon populations are also of Devonian and Ordovician (Famatinian), as well as of Late Neoproterozoic and Mesoproterozoic ages. In both units, there is a conspicuous population of Devonian magmatic zircon grains (from 406 ± 4 Ma to 369 ± 5 Ma), indicative of active magmatism at that time range. The ɛHf values of this population range between -2.84 and -0.7, and the TDM-(Hf) are mostly Mesoproterozoic, suggesting that the primary sources of the Devonian magmatism contained small amounts of Mesoproterozoic recycled crustal components. The chemical composition of the Guaraco Norte Formation corresponds to recycled, mature polycyclic sediment of mature continental provenance, pointing to a passive margin with minor inputs from continental margin magmatic rocks. The chemical signature of the Huaraco Formation indicates that a magmatic arc was the main provenance for sediments of this unit, which is consistent with the occurrence of tuff—mostly in the Arroyo del Torreón Formation and very scarcely in the Huaraco Formation—with a volcanic-arc signature, jointly indicating the occurrence of a Carboniferous active arc magmatism during the deposition of the two units. The Guaraco Norte Formation is interpreted

  17. El Camino del Inca en el Norte Chico chileno

    2011-09-01

    Determine the prehispanic path "Camino del Inca" between the Santa Gracia gully and Vicuña municipality as well as its touristic use. This study is situated in Olla de Caldera, district of La Serena, IV Region, Chile, inhabited by a farming community result from the pre-Hispanic territorial occupations which were successively adapted and transformed since the days of the conquest. In the place there are archaeological and mining sites from the Incaic period, with lots of roads currently used just by locals. The study proposes an Inca path network in the area, refuting the hypothesis of the two North-South parallel paths. The area has no traces of main roads. The IV Region solves the trace with connected trails of varying magnitude. It is difficult to know the origin of these paths. So, we can not confer them an Incaic character with certainty since the roads have been used permanently through time. However, the methodology used in this study, allows to recognize its origins in the field. The review of original documents, particularly of those chroniclers which took part of the conquest, give us us the data extrapolation and the re-interpretation of the facts at its context, narrated by Spaniards, as Pedro Cieza de Leon and Cristobal de Molina, and by indigenous witnesses of the Inca Empire, as Huaman Poma de Ayala and Inca Garcilaso de la Vega. The study collects the original sources in a permanent exercise of contextualization. This study reviews historical and geographical records, contrasting archeological and toponymical data: Indian names of places related to transit and supply are combined and concatenated to test paths on the field. The study addresses the topography and means of transport to contrast them with well-known pre-Hispanic customs to infer their possible origin. We have studied the available maps from the voyages of conquest, especially those of Diego de Almagro and Pedro de Valdivia, passing through the colonial and republican mining boom, to the current records, and finally using Google Earth to track the territory and generate new maps. The field work includes three expeditions to Los Puntiudos - Los Infieles. The first expedition, of interdisciplinary character and archaeological orientation, accuses traces of Inca mining explotation in a wide radius that gathers all similar centers like Condoriaco, Lavaderos de La Corina, Mineral de Arqueros, among many others surrounding the administration of Altovalsol Cuzco. The discussion with archaeologists have located the field work in this Inca mining complex due the roads and its related activities that include archaeological sites, yards, trails, washes, enclosures with apacheta a strategic location with some lordship, the minimum facilities organized in a continuous line of posts, the profusion of rustic ovens of cast iron, and the existence, in a very special place, of the tomb of a lord. The study confirms the existence of a net of roads and refuses the current "two-roads model" which does not consider possible branches. This net of roads cuts through much of the IV region as we have verified thanks to the evidences obtained from the tests in the fieldwork. A second aspect concerns to the existence of straight paths for pedestrians, with a low density of use and minimal facilities. Those paths were avoided since the Spanish conquest due the exclusive practice of the mount. A key finding sets the concept of a unique territory city, continuous and with a very low population density, which was established by the Incas for all the known territory. Those territories were articulated around a network of roads related with the symbolic imaginarium that governs as well its religious-solar domain unifying and total in which the duality urban-rural has no place. The conclusions show that: the religious imposition of the Incas over the dominated ones does not require exclusive solar worship, but to adhere to practices associated with the state: mitas , taxes, collection and distribution of goods, regulation and censuses of the population, as well as population transfers and families formation related with a productive territory. The imperial interests flowed fast and silently over the network of roads, the main imperial structure. The Inca road infrastructure configured the conquered territory itself. Reading the territory implies a broad view of the historical, ecological and social context, as well as their potential and versatility to inhabit, linked to obtain profits without incurring in their deterioration, considering the density allowed by the medium in a given system. A sustainable eco-cultural tourism, of small scale, able to support the enormous human, geographical and archaeological potential that the place owns, could be managed by the local community itself, associated with its customs and traditional practices. This is consistent with the need to implement programs for heritage recognition and conservation. A minority of invited participants could be integrated in the experiential understanding of the territory, rather than just obtaining the benefit of an exotic landscape at an exotic location.

El 80,7% de las chicas y el 80,9% de los chicos ha tenido alguna pareja, bien en el pasado o actualmente.Para la recogida de información se ha elaborado un cuestionario compuesto por 62 ítems que reflejan conductas concretas, representando estas las distintas tipologías de violencia física, psicológica y sexual a través de una escala que indica la frecuencia de cada una de ellas.La mayor incidencia de violencia, tanto ejercida como recibida, corresponde a situaciones de violencia psicológica, seguida de las conductas de agresión física y, por último, aquellas referidas a violencia sexual.Los resultados ponen de manifiesto la necesidad de continuar llevando a cabo trabajos que valoren la magnitud de este fenómeno, el cual tiene unas características concretas en un momento vital tan relevante como es la adolescencia. Es durante este período cuando suelen tener lugar las primeras relaciones de pareja, las cuales, en muchas ocasiones, tienen gran influencia en las vinculaciones que se desarrollarán en el futuro. Se señala, como una de las cuestiones claves, los motivos por los que chicos y chicas ejercen o reciben alguna de las acciones especificadas en el cuestionario, pues de la interpretación y el valor que dan a estas situaciones puede depender cómo las afronten y vivan en el marco de sus relaciones interpersonales.

    Full Text Available Os contos de fada, transmitidos de pais a filhos, pela voz, foram se constituindo num patrimônio precioso de cultura, veiculando experiência humana - e podendo significar para a criança um momento inaugural de "organização da experiência" que a literatura propicia. A proposta, aqui, é um estudo comparativo dos contos Chapeuzinho Vermelho, de Perrault, Fita Verde no Cabelo, de Guimarães Rosa, e Chapeuzinho Amarelo, de Chico Buarque, levando-se em conta que os autores brasileiros estabelecem um inevitável diálogo com o texto-matriz do século XVII. Com efeito, embora as três narrativas enfoquem a questão do crescimento da criança, são apontadas as visões diferentes que elas veiculam: 1. abordagem moralizante e pedagógica do conto de Perrault (os perigos da desobediência infantil, a questão da iniciação sexual; 2. viés metafísico do conto de Guimarães Rosa (confronto com a finitude e a morte, passagem do plano psicológico ao plano metafísico; 3. enfoque da eficácia simbólica da poesia, no conto de Chico Buarque (vitória sobre o medo infantil, mediante o poder da palavra. E tudo levando em conta o que diz Goethe, em sua Teoria das cores: "Quando o artista se deixa levar pelo sentimento, algo de colorido se anuncia".Fairytales, orally passed down from parents to children, have become a precious cultural asset over time, conveying human experience and perhaps even representing an inaugural moment of "organizing experience" for children, a possibility offered by literature. Our proposal here is to carry out a comparative study of the tales Little Red Riding Hood by Perrault, Fita Verde no Cabelo [Green Ribbon in her Hair] by Guimarães Rosa and Chapeuzinho Amarelo [Little Yellow Riding Hood] by Chico Buarque, considering that both Brazilian authors have established an inevitable dialogue with the source text, which dates from the 17th century. Indeed, though all three narratives focus on the issue of child growth, the

    Full Text Available The lomas formations of the Peruvian and Atacama deserts are characterized by both climatic and floristic spatial heterogeneity, as well as non-contiguous pockets of relatively distinct flora. We examined two distinct types of communities in Parque Nacional Pan de Azúcar in Chile, the low-elevation arroyo and bajada community, and the high-elevation fog-zone community. We determined the distribution with elevation of the dominant perennial plant species in a single arroyo community, as well as the distribution of associated climatic characteristics. Climatic conditions (including air temperature, relative humidity, and wind speed and direction were recorded from June, 1999, to March, 2001, for the arroyo, as well as for a medium-elevation inland site with little vegetation, and a high-elevation fog-zone site with copious vegetation. The fog layer, or camanchaca, derived from the marine inversion layer ubiquitous to the Peruvian and Atacama deserts was found to be more persistent, though weaker, during the summer months and somewhat more condensed and shallower in the winter months, with uncharacteristically dry air and high temperatures occurring at and above 400 m elevation during the late fall and early winter of 2000. The reduction or increase in the maximum elevation of the camanchaca or a change in the rainfall regime of the park may have broad implications for the distribution or even presence of certain species in Parque Nacional Pan de Azúcar. Vegetation patterns appear to be strongly dependent on inversion layer development, and perhaps on its subsidence during the winter. A number of species prevalent at low-elevation sites may have little advantage at a high-elevation foggy site, whereas the consistently high humidity at low elevations would be a boon to any desert plant accustomed to low precipitation. If we are to successfully assess the effects of changes in southern Pacific weather patterns, it will become necessary to more

    Full Text Available El abuso de niños y jóvenes hacia colectivos vulnerables merece toda nuestra atención, por ello incidimos en que los animales son un colectivo vulnerable de primer orden. La violencia interpersonal está relacionada con el maltrato animal. Cuando el maltrato animal solía ser trivializado por la gente diciendo: "Es sólo un perro" o "los chicos son chicos", los investigadores y expertos reconocen ahora que la crueldad, maltrato o negligencia en cualquier forma deben tomarse en serio. El maltrato animal es a menudo "la punta del iceberg" y la primera señal de advertencia de un individuo o familia en problemas. Reconociendo el vínculo entre el maltrato animal y otras formas de violencia en la familia, se proporciona a los profesionales en todos los campos una herramienta más para prevenir la violencia en nuestra sociedad. Al trabajar juntos y compartir esta información con los demás, la conciencia pública se elevará y a su vez, aumentará la intervención y la eficacia en la prevención de la violencia y el maltrato familiar en todas sus formas.

    Full Text Available El objetivo de este trabajo fue estudiar, desde el paradigma de usos y gratificaciones, el uso que los estudiantes universitarios españoles (N = 221 hacen de la red social Tuenti, y en qué medida estos usos se asocian con sus niveles de adicción a dicha red social. Además se analizó el papel que los progenitores tienen como facilitadores o inhibidores de dichas tendencias adictivas y el impacto del género. Los resultados muestran cuatro categorías de usos de la red Tuenti: entretenimiento, comunicación a través del muro, comunicación a nivel privado e información social. Además, la actitud positiva hacia la presencia de la madre en la red Tuenti se muestra como un factor de protección de las tendencias adictivas a la red. Por último, se han encontrado diferencias estadísticamente significativas en función del género, tanto en los usos que realizan chicos y chicas, como en sus patrones de adicción a la red Tuenti, de tal manera que los chicos informan de niveles de adicción superiores a los informados por las chicas en el uso de esta red social.

    Full Text Available El objetivo de este trabajo es examinar la influencia de la presencia de la actividad deportiva en el grupo de iguales y la familia en la frecuencia con que los adolescentes realizan actividades deportivas organizadas. Se empleó una muestra de 9821 adolescentes escolarizados españoles de entre 11 y 18 años procedentes de la edición 2010 del Estudio internacional Health Behaviour in School-aged Children (HBSC. Los resultados obtenidos mediante análisis multivariante de Answer Tree, indican que el género fue el mejor predictor de la actividad deportiva organizada, siendo la participación notablemente mayor en los chicos. En cuanto al papel del resto de variables, la presencia de la actividad deportiva en el grupo de iguales y las actividades familiares fueron las variables más influyentes en los chicos. En las chicas, en cambio, la edad surgió como primer factor y la influencia de familia y grupo de iguales fue distinta dependiendo de la edad. En conclusión, familia e iguales parecen ser influencias significativas en la implicación en actividades deportivas, aunque su papel es distinto dependiendo del género y la edad del adolescente.

    The Mokelumne River basin of central California comprises portions of the California Trough and the Sierra Nevada section of the Pacific Mountain system. The California Trough is divisible into four subsections-the Delta tidal plain, the Victor alluvial plain, tlie river flood plains and channels, and the Arroyo Seco dissected pediment. These four subsections comprise the land forms produced by the Mokelumne River and other streams since the Sierra Nevada attained its present height in the Pleistocene epoch. The Victor alluvial plain rises eastward from the Delta plain and abuts on the dissected Arroyo Seco pediment; in the Mokelumne area it is 12 to 16 miles wide and slopes between 5 and 8 feet in a mile. It includes relatively extensive tracts that are intensively cultivated and irrigated with water pumped from wells. The Victor plain has been compounded of overlapping alluvial fans along the western base of the Sierra Nevada. It is prolonged eastward into the pediment by tongues of alluvium along several of the present streams; thus it seems likely that the present stream pattern in the eastern part of the area has been fixed since dissection of the pediment began. Three of the four major streams-the Mokelumne and Cosumnes Rivers and Dry Creek-traverse the Victor plain in trenches which are 15 to 40 feet deep at the heads of their respective alluvial fans but which die out toward the west. The floors of these trenches, the historic flood plains, are from 100 yards to a mile wide. The exceptional major stream, which has not entrenched itself, is the Calaveras River. The Arroyo Seco pediment, which lies east of the Victor plain, was initially at least 8 to 15 miles wide and lay along the western foot of the Sierra Nevada entirely .across the Mokelumne area. Its numerous remnants decline 15 to 35 feet in a mile toward the west. The Sierra Nevada section adjoins and lies east of the California Trough. Its major ridge crests define a volcanic plain whose westward

  5. Influence of diurnal variations in stream temperature on streamflow loss and groundwater recharge

    We demonstrate that for losing reaches with significant diurnal variations in stream temperature, the effect of stream temperature on streambed seepage is a major factor contributing to reduced afternoon streamflows. An explanation is based on the effect of stream temperature on the hydraulic conductivity of the streambed, which can be expected to double in the 0° to 25°C temperature range. Results are presented for field experiments in which stream discharge and temperature were continuously measured for several days over losing reaches at St. Kevin Gulch, Colorado, and Tijeras Arroyo, New Mexico. At St. Kevin Gulch in July 1991, the diurnal stream temperature in the 160-m study reach ranged from about 4° to 18°C, discharges ranged from 10 to 18 L/s, and streamflow loss in the study reach ranged from 2.7 to 3.7 L/s. On the basis of measured stream temperature variations, the predicted change in conductivity was about 38%; the measured change in stream loss was about 26%, suggesting that streambed temperature varied less than the stream temperature. At Tijeras Arroyo in May 1992, diurnal stream temperature in the 655-m study reach ranged from about 10° to 25°C and discharge ranged from 25 to 55 L/s. Streamflow loss was converted to infiltration rates by factoring in the changing stream reach surface area and streamflow losses due to evaporation rates as measured in a hemispherical evaporation chamber. Infiltration rates ranged from about 0.7 to 2.0 m/d, depending on time and location. Based on measured stream temperature variations, the predicted change in conductivity was 29%; the measured change in infiltration was also about 27%. This suggests that high infiltration rates cause rapid convection of heat to the streambed. Evapotranspiration losses were estimated for the reach and adjacent flood plain within the arroyo. On the basis of these estimates, only about 5% of flow loss was consumed via stream evaporation and stream-side evapotranspiration

    Full Text Available Se estudio la correlación entre dieta y morfología de 19 especies de peces del arroyo Manantiales, cabecera del río samborombón, provincia de Buenos Aires, Argentina. Las especies fueron clasificadas en cuatro grupos tróficos: carnívoros, omnívoros, insectívoros y detritívoros- alguívoros. Se analizaron 12 atributos ecomor-fológicos relacionados con el uso del hábitat y la alimentación con el fin de distinguir patrones ecomorfológicos de las especies y de las especies con el alimento consumido. Se utilizaron técnicas de análisis univariado y multivariado para determinar agrupamientos de especies utilizando los atributos ecomorfológicos y la dieta como descriptores. Los carnívoros se relacionaron con un buen desarrollo de cabeza, boca, aletas caudal y pectoral; y en general con cuerpos comprimidos. Los omnívoros constituyeron un grupo más heterogéneo. Las formas nectónicas de este grupo se relacionaron con un cuerpo comprimido, ojos laterales y tamaño relativamente pequeño de las aletas pectorales y aleta caudal; las formas nectobentónicas se relacionaron con boca pequeña, cuerpo fusiforme y pedúnculo caudal largo; y las formas bentónicas, con cuerpo deprimido, ojos de posición dorsal, boca ínfera y tubo digestivo largo. La única especie nectónica consumidora de insectos sobre la superficie se caracterizó por un cuerpo fuertemente comprimido, ojos laterales, aleta caudal grande y boca grande orientada hacia arriba. Los detritívoros-alguívoros presentaron un tubo digestivo largo, boca ínfera o terminal y aletas caudales largas. La relación significativa dieta-ecomorfología permite sostener que peces de dieta similar convergen hacia atributos ecomorfológicos comunes.The present study addresses the correlation between diet and morphology of 19 fish species that inhabit the Manantiales stream at the headwaters of the samborombón river, Buenos Aires province, Argentina.

    The marine deposits of the Vaca Muerta Formation (Tithonian-Berriasian) houses one of the most diverse Late Jurassic ichthyofaunas of Gondwana. However, most of the specimens remain undescribed. Jurassic fishes have been recovered from several localities at Neuquén Province (i.e., Picún Leufú, Plaza Huincul, Cerro Lotena, Portada Las Lajas, Los Catutos, and Arroyo Covunco) but also from Mendoza Province (i.e., La Valenciana, Los Molles, and Arroyo del Cajón Grande). Presently, the fish fauna of Los Catutos, near Zapala city (Neuquén Province), has yielded the highest number of specimens, which are taxonomically and morphologically diverse. At Los Catutos locality, the Vaca Muerta Formation is represented by the Los Catutos Member, which is considered the only lithographic limestones known in the Southern Hemisphere. Here, we review the Tithonian fish faunas from the Vaca Muerta Formation. During Late Jurassic times, the actual Argentinian territory could have been a morphological diversification center, at least for some actinopterygian groups. The apparently lower species diversity recorded in marine Jurassic ichthyofaunas of Argentina (and some Gondwanan countries) in comparison with Chilean and European fish faunas could be related to the fish paleontological research history in Gondwana and the low number of detailed studies of most of specimens recorded.

    Full Text Available Dentre os fatores que contribuem para reduzir a produtividade das lavouras de milho estão as pragas, destacando-se a lagarta-do-cartucho, Spodoptera frugiperda, a qual pode reduzir a produção em até 34%. Um dos métodos de controle de pragas, cujo custo é reduzido e não causa efeitos indesejáveis ao ambiente, é o desenvolvimento de cultivares resistentes. Diversas fontes de resistência foram identificadas, linhagens desenvolvidas, registradas e liberadas ao público; entretanto, pouca informação tem sido veiculada a respeito dos mecanismos e causas dessa resistência. O objetivo do presente trabalho foi estudar os mecanismos de resistência, não-preferência e antibiose em genótipos de milho selecionados, com resistência a S. frugiperda. Os ensaios foram conduzidos em laboratório e em casa de vegetação da EMBRAPA/CNPMS. O genótipo CMS 14C apresentou antibiose influindo negativamente na biologia de S. frugiperda. 'CMS 24' e 'CMS 23' apresentaram também esse mecanismo, porém em menor intensidade. Foi constatada não-preferência alimentar das lagartas para 'Zapalote Chico' e 'BR 201'. Não-preferência para oviposição foi constatada em 'CMS 14C' e 'Zapalote Chico'.

    Full Text Available In the present paper, the geomorphological and sedimentary characteristics of the continental sequences exposed on the coastal cliffs and surrounding areas of the Centinela del Mar locality are described and interpreted. Fourteen lithofacies are defined, their relation, geometry and structure are represented using transversal and longitudinal detailed profiles. In the basal and medium sector of the profile, facies of different degrees of transport and aqueous rework were recognized. In the superior sector, a succession of marine peri-coastal facies corresponding to the «Belgranense» transgression (=Fm. Pascua were identified, ending the secuence with relictual eolic facies. The different historical interpretations are discussed, homologating the units referred previously with the ones proposed on this paper. These units are correlated with those defined in the allostratigrapic scheme proposed by other authors for the area covered between Playa San Carlos and Arroyo Chapadmalal. This allowed recognize for the area under study the presence of the Punta San Andrés and Arroyo Lobería Alloformations (basal-medium and superior sector, respectively. Between these two entities, a association of well defined progradant marine facies are found and named on this paper as Centinela del Mar Alloformation. Finally, the information gathered here (magnetostratigraphy, radiometric dating, stratigraphic correlations, etc indicates, at least preliminarily, that the secuence of Centinela del Mar corresponds to the Ensenadense-Lujanense interval (Lower Pleistocene - Holocene.

    Full Text Available El área de estudio abarca los valles inferiores de los ríos Limay y Neuquén, en la proximidad de la confluencia de estos dos ríos, cuyas aguas conforman el río Negro. El paisaje caracteriza por la presencia de extensas mesetas áridas disectadas por valles con cursos de agua permanentes. Diversas actividades se desarrollan en el área, dentro de las cuales la fruticultura, acompañada de cultivos hortícolas, son dominantes en las terrazas bajo riego de los valles de los mencionados ríos. A su vez, la explotación de hidrocarburos (petróleo y gas adquiere relevancia ambiental, dado que en muchos lugares de la mencionada área de cultivos se encuentran instalaciones relacionadas con la extraccción de estos combustibles fósiles. La economía del petróleo constituye uno de los principales ingresos de las provincias de Neuquén y Río Negro. Se trata de la zona más poblada del norte de la Patagonia, donde se asientan las localidades de Neuquén, Senillosa, Plottier, Centenario y Vista Alegre, en la provincia del Neuquén, y Cinco Saltos, Fernández Oro, Cipolletti y Contraalmirante Cordero en la provincia de Río Negro. En estos centros urbanos se ha producido, en las últimas décadas, un crecimiento de población sostenido y de gran intensidad, princi­palmente en aquellos localizados en la provincia del Neuquén. Este crecimiento no fue acompañado por una adecuada planificación por parte de los organismos locales y provinciales lo que da como resultado la manifestación de diversos conflictos ambien­tales. Los mismos se asocian a nuevas formas en el uso del suelo, como es el avance de áreas urbanas y la explotación de petróleo y gas sobre suelos con producción agrícola o aptos para ella, lo que ocasiona la retracción de las tierras de cultivo. Asimismo, los cambios en las modalidades de asentamiento se manifiestan en la incorporación al ámbito urbano de áreas geomorfológicamente inestables ya sea en las riberas de los r

    Full Text Available La ecología trófica de insectos acuáticos ha sido desarrollada en zonas templadas. Sin embargo, la asignación de un taxón a un grupo trófico no representa necesariamente el mismo en otras regiones. En la Región Neotropical, el conocimiento sobre la ecología trófica de larvas de tricópteros es incompleta y la literatura sobre este tema rara vez se ocupa del análisis de los hábitos alimentarios de larvas con datos cuantitativos a nivel de especie. Este trabajo aporta al conocimiento de las características tróficas de la trichopterofauna del Neotrópico. Se describen los hábitos alimentarios de tres especies de Trichoptera registrados en arroyos de Yungas de Argentina y Bolivia: Marilia cinerea, M. elongata y M. flexuosa. Se seleccionaron 15 larvas de cada especie en 13 arroyos de Yungas surandinas para analizar las piezas bucales y el contenido estomacal. El solapamiento de nicho trófico se estimó mediante el índice de Schoener. El análisis de la dieta reveló que las especies difieren en la preferencia de los ítems registrados, hábitat y forma de sus mandíbulas. Las larvas de M. cinerea habitan en superficies de rocas emergentes. Poseen mandíbulas fuertes con grandes zonas molares y consumen principalmente invertebrados. Esta evidencia permite asignarle el grupo funcional depredador. M. elongata consume material fino, sus mandíbulas tienen forma de cuchara y su ubicación en zonas de bajo flujo permite asignarle una estrategia colectora-recolectora. Las larvas de M. flexuosa habitan en fondos arenosos de arroyos de montaña, tienen fuertes piezas bucales en forma de cuchara y una dieta dominada por hojarasca y material fino. Pertenecen al grupo funcional triturador, secundariamente colector-recolector. Sugerimos que la asignación de grupo funcional a nivel de género no es recomendable para Marilia. Se recomiendan mayores estudios a nivel de especie.

    (I)In this project, the Beta-­decay Paul Trap, an open-­geometry RFQ ion trap that can be instrumented with sophisticated radiation detection arrays, is used for precision β-­decay studies. Measurements of β-­decay angular correlations, which are sensitive to exotic particles and other phenomena beyond the Standard Model (SM) of particle physics that may occur at the TeV-­energy scale, are being performed by taking advantage of the favorable properties of the mirror 8Li and 8B β± decays and the benefits afforded by using trapped ions. By detecting the β and two α particles emitted in these decays, the complete kinematics can be reconstructed. This allows a simultaneous measurement of the β-­n, β-­n-­α, and β-α correlations and a determination of the neutrino energy and momentum event by event. In addition, the 8B neutrino spectrum, of great interest in solar neutrino oscillation studies, can be determined in a new way. Beta-­delayed neutron spectroscopy is also being performed on neutron-­rich isotopes by studying the β-­decay recoil ions that emerge from the trap with high efficiency, good energy resolution, and practically no backgrounds. This novel technique is being used to study isotopes of mass-­number A~130 in the vicinity of the N=82 neutron magic number to help understand the rapid neutron-­capture process (r-­process) that creates many of the heavy isotopes observed in the cosmos. (II)A year-long CHICO2 campaign at ANL/ATLAS together with GRETINA included a total of 10 experiments, seven with the radioactive beams from CARIBU and three with stable beams, with 82 researchers involved from 27 institutions worldwide. CHICO2 performed flawlessly during this long campaign with achieved position resolution matching to that of GRETINA, which greatly enhances the sensitivity in the study of nuclear γ-­ray spectroscopy. This can be demonstrated in our results on 144Ba and 146

    Velázquez, María S; Cabello, Marta N; Elíades, Lorena A; Russo, María L; Allegrucci, Natalia; Schalamuk, Santiago

    Arbuscular mycorrhizal fungi (AMF) increase the uptake of soluble phosphates, while phosphorus solubilizing fungi (S) promote solubilization of insoluble phosphates complexes, favoring plant nutrition. Another alternative to maintaining crop productivity is to combine minerals and rocks that provide nutrients and other desirable properties. The aim of this work was to combine AMF and S with pyroclastic materials (ashes and pumices) from Puyehue volcano and phosphate rocks (PR) from Rio Chico Group (Chubut) - to formulate a substrate for the production of potted Lactuca sativa. A mixture of Terrafertil®:ashes was used as substrate. Penicillium thomii was the solubilizing fungus and Rhizophagus intraradices spores (AMF) was the P mobilizer (AEGIS® Irriga). The treatments were: 1) Substrate; 2) Substrate+AMF; 3) Substrate+S; 4) Substrate+AMF+S; 5) Substrate: PR; 6) Substrate: PR+AMF; 7) Substrate: PR+S and 8) Substrate: PR+AMF+S. Three replicates were performed per treatment. All parameters evaluated (total and assimilable P content in substrate, P in plant tissue and plant dry biomass) were significantly higher in plants grown in substrate containing PR and inoculas with S and AMF. This work confirms that the combination of S/AMF with Puyehue volcanic ashes, PR from the Río Chico Group and a commercial substrate promote the growth of L. sativa, thus increasing the added value of national geomaterials.

    Full Text Available Este estudio ex post facto aporta una aproximación psicosocial a la problemática del consumo juvenil de sustancias psicoactivas y a las actitudes hacia la experimentación. El objetivo fundamental consiste en la vinculación entre droga y género, ofreciendo un análisis de las diferencias inter-género a nivel actitudinal y de las ventajas de cuatro programas de intervención psicosocial con seguimiento a un año. Para ello, se ha seleccionado un colectivo de 755 adolescentes de entre doce y dieciocho años escolarizados en cuatro centros de educación secundaria del Principado de Asturias (España. Se ha comprobado que los adolescentes manifiestan una mayor sensibilización ante la problemática de la drogodependencia y en los chicos se han obtenido actitudes de mayor permisividad hacia el uso/abuso de drogas. De los cuatro programas didáctico-preventivos empleados se confirma el mayor efecto preventivo de las modalidades de intervención familiar y sensibilización básica, mientras que el programa Experto en Drogas parece fortalecer más las actitudes de resistencia frente a la experimentación en chicos. En cambio, en la modalidad de intervención informativa no se han obtenido diferencias inter-género significativas en las actitudes reportadas.

In the basal and medium sector of the profile, facies of different degrees of transport and aqueous rework were recognized. In the superior sector, a succession of marine peri-coastal facies corresponding to the Belgranense transgression (=Fm. Pascua) were identified, ending the sequence with relictual eolic facies. The different historical interpretations are discussed, homologating the units referred previously with the ones proposed on this paper. These units are correlated with those defined in the allostratigrapic scheme proposed by other authors for the area covered between Playa San Carlos and Arroyo Chapadmalal. This allowed recognize for the area under study the presence of the Punta San Andres and Arroyo Loberia Alloformations (basal-medium and superior sector, respectively). Between these two entities, a association of well defined progradant marine facies are found and named on this paper as Centinela del Mar Alloformation. Finally, periferithe information gathered here (magnetostratigraphy, radiometric dating, stratigraphic correlations, etc) indicates, at least preliminarily, that the sequence of Centinela del Mar corresponds to the Ensenadense- Lujanense interval (Lower Pleistocene - Holocene).

    Full Text Available Se determinó la carga de sedimentos en suspensión (SS y fósforo (P durante even­tos de lluvia-escorrentía en un arroyo de ca­becera, que drena una cuenca rural ubicada en Galicia (NO España. Asimismo, se trató de conocer las principales fuentes de SS y P exportados. Se observaron acusadas dife­rencias en la carga de SS y P entre eventos, lo cual se asocia con el volumen de esco­rrentía, así como con el desarrollo de surcos y cárcavas efímeras en parcelas de cultivo bien conectadas con la red de drenaje. La carga de SS osciló entre 0,8 y 21,0 t mientras que la de P varió entre 2,5 y 20,0 kg. El fósforo parti­culado (PP mostró relaciones significativas con los SS, lo que indica el origen erosivo de una parte importante de P, especialmente considerando que el PP supone más de un 80% del P exportado en cada evento.This work examines the suspended sedi­ment (SS and phosphorus (P load during rainfall-runoff events in a headwater stream which drains a rural catchment located in Galicia (NW Spain. Another objective is to know the major sources of SS and P ex­ported. Important differences in the SS and P load between events were found, which is associated with the runoff volume, as well as to develop of rills and ephemeral gullies in cultivated fields well connected to the drainage network. The SS load ranged be­tween 0.8 and 21.0 t, while the P load varied between 2.5 and 20.0 kg. The particulate phosphorus (PP showed significant rela­tionship with SS, which indicates the ero­sive origin of P, especially considering that PP means more 80% of P exported each event.

Os parâmetros biológicos avaliados foram peso, duração e viabilidade das fases larval e pupal. Verificou-se que o extrato provocou alongamento da fase larval e redução dos pesos larval e pupal e que os genótipos resistentes não confirmaram esse comportamento pois quando comparados ao genótipo suscetível, apenas reduziram o peso pupal. Não houve interação significativa entre os fatores genótipo e extrato.The effect of the ethyl acetate extract of leaves and branches of Trichilia pallida was evaluated (at 0.001% on larvae of S. frugiperda, fed on leaves of the corn genotypes 'Zapalote Chico', 'CMS 14C' and 'ESALQ-PB-4', considered resistant to this pest, and the susceptible genotype 'Piranão'. The parameters evaluated were length, weight and viability of larval and pupal stages. The extract increased the length of the larval stage, and larval and pupal weight, while resistant genotypes only reduced the pupal weight, did however not confirm the resistant behaviour. There was no interaction between genotype and extract.

  6. Dating floodplain sediments using tree-ring response to burial

    2005-01-01

    Floodplain sediments can be dated precisely based on the change in anatomy of tree rings upon burial. When a stem of tamarisk (Tamarix ramosissima) or sandbar willow (Salix exigua) is buried, subsequent annual rings in the buried section resemble the rings of roots: rings become narrower, vessels within the rings become larger, and transitions between rings become less distinct. We combined observations of these changes with tree-ring counts to determine the year of deposition of sedimentary beds exposed in a 150-m-long trench across the floodplain of the Rio Puerco, a rapidly filling arroyo in New Mexico. This method reliably dated most beds thicker than about 30 cm to within a year of deposition. Floodplain aggradation rates varied dramatically through time and space. Sediment deposition was mostly limited to brief overbank flows occurring every few years. The most rapid deposition occurred on channel-margin levees, which migrated laterally during channel narrowing. At the decadal timescale, the cross-section-average sediment deposition rate was steady, but there was a shift in the spatial pattern of deposition in the 1980s. From 1936 to 1986, sediment deposition occurred by channel narrowing, with little change in elevation of the thalweg. After 1986 sediment deposition occurred by vertical aggradation. From 1936 to 2000 about 27 per cent of the arroyo cross-section filled with sediment. The rate of filling from 1962 to 2000 was 0·8 vertical m/decade or 85 m2/decade.

    Mangroves are essential for protecting coastal environments and biodiversity; however few studies encompass the distribution of radionuclides in soils from these ecosystems. By applying high resolution gamma-ray spectrometry, natural radionuclides were quantified in soils from the Chico Science Mangrove and Rio Formoso Mangrove (RFM), areas subjected to different human impacts. The activity concentrations of 226 Ra and 228 Ra were quite similar for the mangroves despite the differences found for 40 K. Moreover, no correlation with the environmental impacts on the mangroves was observed, although RFM soil was 40 K-enriched compared to deep sediments from other estuaries in the world. (author)

    2012-08-27

    In Bahía de la Ascensión, Mexico, 'casitas' (large artificial shelters) are extensively used to harvest Caribbean spiny lobsters Panulirus argus. After the discovery of a pathogenic virus, Panulirus argus virus 1 (PaV1), in these lobsters, laboratory experiments revealed that PaV1 could be transmitted by contact and through water, and that lobsters avoided shelters harboring diseased conspecifics. To examine these issues in the context of casitas, which typically harbor multiple lobsters of all sizes, we examined the distribution and aggregation patterns of lobsters in the absence/presence of diseased conspecifics (i.e. visibly infected with PaV1) in 531 casitas distributed over 3 bay zones, 1 poorly vegetated ('Vigía Chico', average depth: 1.5 m) and 2 more extensively vegetated ('Punta Allen': 2.5 m; 'Los Cayos': 2.4 m). All zones had relatively high indices of predation risk. Using several statistical approaches, we found that distribution parameters of lobsters were generally not affected by the presence of diseased conspecifics in casitas. Interestingly, however, in the shallower and less vegetated zone (Vigía Chico), individual casitas harbored more lobsters and lobsters were actually more crowded in casitas containing diseased conspecifics, yet disease prevalence was the lowest in lobsters of all sizes. These results suggest that (1) investment in disease avoidance by lobsters is partially modulated by local habitat features, (2) contact transmission rates of PaV1 may be lower in nature than in the laboratory, and (3) water-borne transmission rates may be lower in shallow, poorly vegetated habitats more exposed to solar ultraviolet radiation, which can damage viral particles.

    Full Text Available Introducción: Es un estudio de intervención de diseño longitudinal con una duración de 6 meses, de grupo único con evaluación antes-después, que pretende evaluar la eficacia de un programa propioceptivo como método para mejorar el control postural en jóvenes deportistas. Métodos: La muestra de estudio fue de 28 jugadores/as de voleibol (15-18 años. Se tomaron datos una primera vez antes de un primer trimestre sin intervención, una segunda ocasión, una vez finalizado este periodo, y en una tercera ocasión después de un segundo trimestre con entrenamiento. El entrenamiento propioceptivo utilizado se realizó mediante el método Terapia Reequilibradora del Aparato Locomotor (TRAL. La estabilidad corporal se midió calculando el área de desviación del centro de presiones mediante una plataforma de fuerzas con sensores electrónicos Buratto Advanced. Las posiciones analizadas fueron la posición unipodal con ojos abiertos y cerrados de las dos piernas. Resultados: Reducción significativa del área de desviación del centro de presiones en los cuatro tests en el caso de las chicas y sólo reducción significativa en uno de los tests con el grupo de chicos. Conclusiones: El entrenamiento con TRAL mejora el control postural en chicas y produce tendencia a la mejoría en el caso de los chicos. Son necesarios nuevos estudios con grupo control y mayor muestra.

    Full Text Available El objetivo de este trabajo se centra en conocer el uso que hacen los alumnos de las estrategias de aprendizaje, viendo si existen diferencias en función de su origen nacional. Para ello, se aplicó el Cuestionario de Estrategias de Aprendizaje (CEA a un total de 70 estudiantes –37 españoles y 33 inmigrantes– de 1º y 4º ESO, procedentes de cuatro centros, de diferente titularidad, ubicados en la provincia de Lugo (Galicia. Para el análisis estadístico se empleó el programa SPSS 15.0. Nuestros resultados indican que los alumnos, españoles e inmigrantes, muestran un nivel adecuado en el uso que hacen de las estrategias de aprendizaje sin que se hayan registrado diferencias significativas entre ambos grupos. Sin embargo, sí se encontraron diferencias significativas en función del género. Concretamente en la subescala de control emocional, en la que los chicos españoles obtuvieron una puntuación más alta que los inmigrantes. Además, si tenemos en cuenta el curso, vemos cómo los alumnos de 1º ESO españoles alcanzan puntuaciones más elevadas en la escala de sensibilización y en la subescala de control emocional frente a los chicos inmigrantes de su mismo curso. Por otro lado, aunque los estudiantes inmigrantes de 4º ESO –varones– obtienen puntuaciones más bajas en las subescalas de organización y transferencia frente a sus compañeros de 1º ESO, manifiestan un mayor control emocional

    Full Text Available Chicas y chicos adolescentes hacen un uso diferente de las redes sociales online, y las chicas presentan un mayor riesgo de verse perjudicadas por un uso no adaptativo. El objetivo de este estudio era investigar en qué medida los adolescentes se presentan en términos de estereotipos de género en sus perfiles de Facebook. Los participantes, 623 usuarios de Facebook de ambos sexos, contestaron el Bem Sex Role Inventory (BSRI y el Personal Well-being Index (PWI. En la primera fase, respondieron sobre cómo ven a un adulto típico en términos de estereotipos de género. En la segunda fase, la mitad de ellos contestó el BSRI en relación a cómo se ven a sí mismos, y la otra mitad cómo se presentan en Facebook. Los resultados muestran que los adolescentes se consideran más sexualmente indiferenciados que un adulto típico de su mismo sexo, tanto en su auto-percepción como en su presentación en Facebook. Se confirma que el bienestar psicológico de las chicas baja considerablemente con la edad, y que está asociado a un mayor grado de masculinidad. Se concluye que los adolescentes producen representaciones verdaderas en sus perfiles de Facebook, y que existe una tendencia hacia una auto-concepción y auto-presentación más sexualmente indiferenciada con una leve preferencia por rasgos masculinos, tanto en chicos como en chicas; además, la masculinidad está asociada a un mayor grado de bienestar psicológico.

    Connectivity between populations plays a key role in the long-term persistence of species in fragmented habitats. This is of particular concern for biodiversity preservation in drylands, since water limited landscapes are typically characterized by little suitable habitat cover, high habitat fragmentation, harsh matrices, and are being rapidly degraded at a global scale. In this study, we modelled landscape connectivity between 11 guanaco Lama guanicoe populations in Chile's arid Norte Chico, a region that supports the last remnant coastal populations of this emblematic herbivore indigenous to South America. We produced a habitat suitability model to derive a regional surface resistance map, and used circuit theory to map functional connectivity, investigate the relative isolation between populations, and identify those that contribute most to the patch connectivity network. Predicted suitable habitat for L. guanicoe represented about 25% of the study region (i.e., 29,173 km 2 ) and was heterogeneously distributed along a continuous stretch along the Andes, and discontinuous patches along the coast. As a result, we found that high connectivity current flows in the mid and high Andes formed a wide, continuous connectivity corridor, enabling connectivity between all high Andean populations. Coastal populations, in contrast, were more isolated. These groups demonstrate no inter-population connectivity between themselves, only with higher altitude populations, and for two of them, animal movement was linked to the effectiveness of wildlife crossings along the Pan-American highway. Our results indicate that functional connectivity is an issue of concern for L. guanicoe in Chile's Norte Chico, implying that future conservation and management plans should emphasize strategies aimed at conserving functional connectivity between coastal and Andean populations, as well as the protection of habitat patches likely to act as stepping stones within the connectivity network.

    We investigated genetic differentiation and migration patterns in a small livebearing fish, Poecilia mexicana, inhabiting a sulfidic Mexican limestone cave (Cueva del Azufre). We examined fish from three different cave chambers, the sulfidic surface creek draining the cave (El Azufre) and a nearby surface creek without the toxic hydrogen sulphide (Arroyo Cristal). Using microsatellite analysis of 10 unlinked loci, we found pronounced genetic differentiation among the three major habitats: Arroyo Cristal, El Azufre and the cave. Genetic differentiation was also found within the cave between different pools. An estimation of first-generation migrants suggests that (i) migration is unidirectional, out of the cave, and (ii) migration among different cave chambers occurs to some extent. We investigated if the pattern of genetic differentiation is also reflected in a morphological trait, eye size. Relatively large eyes were found in surface habitats, small eyes in the anterior cave chambers, and the smallest eyes were detected in the innermost cave chamber (XIII). This pattern shows some congruence with a previously proposed morphocline in eye size. However, our data do not support the proposed mechanism for this morphocline, namely that it would be maintained by migration from both directions into the middle cave chambers. This would have led to an increased variance in eye size in the middle cave chambers, which we did not find. Restricted gene flow between the cave and the surface can be explained by local adaptations to extreme environmental conditions, namely H2S and absence of light. Within the cave system, habitat properties are patchy, and genetic differentiation between cave chambers despite migration could indicate local adaptation at an even smaller scale.

In Paraná, there were about 167 polish ethnic schools in the 1930s. Among the main features of this type of school are the teaching ministered in the group’s mother language, as well as the teaching of the culture and history of the home country. Most of those schools were created and sustained by the community, and even when there were Brazilian public schools in the region, the polish colonists gave preference to their own schools, due to the maintenance of their cultural features.

    Paleoparasitology is the study of parasite remains from archaeological and paleontological sites. Raptor pellets can be used as source for paleoparasitological information in archaeological sites. However, this zooarchaeological material has been scarcely studied. Epullán Chica (ECh) is an archaeological site in northwestern Patagonia. This cave yielded remains from more than 2000 years before present. The aim of this paper was to study the parasite remains found in owl pellets from the archaeological site ECh, and to discuss the paleoparasitological findings in an archaeological context. Twenty two raptor pellets were examined for parasites. The pellets were whole processed by rehydration in a 0.5% water solution of trisodium phosphate, followed by homogenization, filtered and processed by spontaneous sedimentation. Eight out of 22 bird pellets examined were positive for parasites from reptiles and rodents. Representatives of 12 parasite taxa were recorded; nine of this parasitic species were reported for the first time from ancient samples from Patagonia. This is the first time that pellets give evidences of ancient reptile parasites from archaeological contexts. It is noteworthy that Late Holocene hunter-gatherers of the upper Limay River basin, could have been exposed to some of these zoonotic parasites. Future paleoparasitological studies on owl pellets may reflect even more the parasitological diversity of all micromammal and reptile species presents in ancient times.

  3. Provenance study of obsidian samples by using portable and conventional X ray fluorescence spectrometers. Performance comparison of both instrumentations

    The potentiality of portable instrumentation lies on the possibility of the in situ determinations. Sampling, packaging and transport of samples from the site to the laboratory are avoided and the analysis becomes non destructive at all. However, detection limits for light elements are, in most cases, a limitation for quantification purposes. In this work a comparison between the results obtained with an X ray fluorescence spectrometer laboratory based and a portable instrument is performed. A set of 76 obsidian archaeological specimens from northwest Patagonia, Argentina was used to carry out the study. Samples were collected in the area of the middle and high basin of the Limay River. The analytical information obtained with both instrumentations was complemented with Principal Component Analysis in order to define groups and identify provenance sources. The information from both instruments allows arriving to the same conclusion about sample provenance and mobility of hunter-gatherer groups. Three groups of sources were identified in both cases matching with the geographical information. Also, same sets of outlier samples or not associated to these sources were found. Artifact samples were associated mainly to the closest sources, but some of them are related to sources located more than three hundred kilometers, evidencing the large mobility of the hunter-gatherers by the obsidian interchange. No significant differences between concentrations values obtained by laboratory based instrument and portable one were found. (author)

    A program of hydrogeologic investigation has been carried out to determine the likelihood of contaminant movement to the saturated zone from near the ground surface at Lawrence Livermore National Laboratory (LLNL). A companion survey of potential contaminant sources was also conducted at the LLNL. Water samples from selected LLNL wells were analyzed to test the water quality in the uppermost part of the saturated zone, which is from 14 to 48 m (45 to 158 ft) beneath the surface. Only nitrate and tritium were found in concentrations above natural background. In one well, the nitrate was slightly more concentrated than the drinking water limit. The nitrate source has not been found. The tritium in all ground-water samples from wells was found far less concentrated than the drinking water limit. The extent of infiltration of surface water was traced with environmental tritium. The thickness and stratigraphy of the unsaturated zone beneath the LLNL, and nearby area, was determined with specially constructed wells and boreholes. Well hydrograph analysis indicated where infiltration of surface water reached the saturated ground-water system. The investigation indicates that water infiltrating from the surface, through alluvial deposits, reaches the saturated zone along the course of Arroyo Seco, Arroyo Las Positas, and from the depression near the center of the site where seasonal water accumulates. Several potential contaminant sources were identified, and it is likely that contaminants could move from near the ground surface to the saturated zone beneath LLNL. Additional ground-water sampling and analysis will be performed and ongoing investigations will provide estimates of the speed with which potential contaminants can flow laterally in the saturated zone beneath LLNL. 34 references, 61 figures, 16 tables

    Understanding the effects of global climate disruption on biodiversity is important to future conservation efforts. While taxonomic diversity is widely studied, functional diversity of plants, and recently animals, is receiving increasing attention. Most studies of mammals are short-term, focus on temperate habitats, and rely on traits described in the literature rather than generating traits from observations. Unlike previous studies, this long-term field study assessed the factors driving the functional and taxonomic diversity of small-mammal assemblages in dry tropical forests using both traits recorded from literature and a demographic database. We assessed the drivers (abundance and biomass, temperature and rainfall) of taxonomic richness and functional diversity for two rain-driven seasons in two adjacent but distinct forests-upland and lowland (arroyo or riparian) forests. Our analysis found that rainfall, both seasonal and atypical, was the primary factor driving functional and taxonomic diversity of small-mammal assemblages. Functional responses differed between the two types of forests, however, with effects being stronger in the harsher conditions of the upland forests than in the less severe conditions prevailing in the arroyo (riparian) forest. The latter also supports a richer, more diverse, and more stable small-mammal assemblage. These findings highlight the importance of climate to tropical biological diversity, as extreme climate events (hurricanes, droughts and floods) and disruption of rainfall patterns were shown to decrease biodiversity. They also support the need to preserve these habitats, as their high taxonomic diversity and functional redundancy makes them resilient against global climate disruption and local extreme events. Tropical dry forests constitute a potential reservoir for biodiversity and the ecosystem services they provide. Unfortunately, these forests are among the most endangered terrestrial ecosystems because of

El área donde el río Cajas vuelca sus aguas al río Yavi es fértil en restos arqueológicos, el sitio más conocido es el Antigal de Yavi Chico, pero también se encuentran otros sitios menores, unos con arte rupestre y otros con hallazgos de artefactos líticos, y otros con restos cerámicos y óseos. Este sector de la cuenca está afectado por los procesos erosivos, es así que luego de los frecuentes derrumbes es posible ver los restos culturales en las escarpas expuestas. Se localizaron tres enterratorios: en urna, en el sitio denominado La Palca; otro en el antigal de Yavi Chico, y un tercero en Portillo. El análisis desde la antropología biológica, de restos humanos provenientes de sitios arqueológicos, aporta información importante acerca de las poblaciones que los habitaron, el estado sanitario en general, la alimentación, patologías, edad y sexo. De los análisis surge: una elevada incidencia de desgaste dental que afecta por igual a ambos sexos provocado probablemente por el tipo de alimentación, también se observan perdidas de piezas e indicios de periodontitis y en uno de los conjuntos óseos se advierte señas dejadas por enfermedades óseas (osteofitosis, deformación del esternón. Se espera poder contar en el futuro con una muestra más abundante para poder delinear de esta forma un panorama acerca de la salud de los pueblos prehispánicos de este sector de nuestra Puna.

    Full Text Available The anthropometric characteristics of athletes can determine their sporting performance. For this reason, we’ve defined the somatotype of young volleyball players in order to be able to control their sports training and to ensure their appropriate athletic development. In the present investigation 154 male and female volleyball players (aged from 12 to 14 years were analyzed. Data were collected according to the ISAK protocol. The results show an endomesomorphic profile for male and female volleyball players agreeing with the predominant profile at these ages. However, after comparing these data with results obtained in other studies, we observed a certain homogeneity in the male somatotype, invalidating the current trend of using this parameter as criteria to select young sports talent. However, somatotype could be a factor to take into account with female athletes, since their profile is much more heterogeneous.

    Full Text Available Cities are living entities that change almost daily but its people are aware of it. They forget the state before the great changes and people become accustomed to the new urban image. In a hundred years a city can completely change its appearance and even its essence. This is the case of Granada, where its historic center was heavily modified during the nineteenth century. These changes have been studied by a project analyzing and virtually rebuilding the historic city. The work ranges from the Rey Chico, below the Alhambra palace, to Puerta Real, restoring the image of the city around 1831, based on the engravings and descriptions of romantic travelers, on the previous alignments and transformations in old pictures.

    2014-06-01

    Full Text Available A lo largo de décadas de actividad carbonífera en la cuenca de Río Turbio ubicada al sudoeste de la provincia de Santa Cruz en la República Argentina, se ha generado una serie de pasivos ambientales entre los cuales se encuentran los depósitos de material estéril denominados escombreras, las piletas de lodos y los sedimentos del curso de agua receptor de efluentes, el arroyo San José. La presencia de estos pasivos, ha ocasionado en distintas partes del mundo complicaciones debido a la naturaleza ácida de las escorrentías que afectan directamente fuentes de agua, superficiales y subterráneas, localizadas en la vecindad de dichos depósitos. El problema se produce cuando dicha acidez no puede ser neutralizada, lo cual ocasiona la generación de lixiviados de metales pesados en las escombreras o redisolución de los que se encuentran depositados como sedimentos en los cursos superficiales. Por tal motivo en este trabajo se realiza una evaluación preliminar del contenido metálico de los depósitos de estériles y de los sedimentos del arroyo San José y de la capacidad de generación ácida de los primeros. Se pretende con ello obtener una información básica que permita un diseño experimental científico para caracterizar dichos depósitos y evaluar el impacto que están produciendo. Como conclusión se pudo corroborar la hipótesis inicial de existencia de contenido metálico en escombreras y sedimentos y un potencial neto de generación ácida de las primeras. Además se determinó la necesidad de investigar el origen de altos contenidos metálicos en sedimentos de zonas alejadas de la producción.

    Full Text Available El presente trabajo está centrado en el estudio de la calidad de agua de los cursos que integran la cuenca hidrográfica del río Quequén Salado, Argentina, con el objeto de evaluar su empleo para riego suplementario. Se realizaron determinaciones de salinidad y sodicidad en muestras de agua tomadas en distintos tramos de los ríos y arroyos de la cuenca, así como en las lagunas más importantes, durante la primavera y el verano de los años 1998, 1999 y 2000. El estudio se cumplimentó con la caracterización química de los principales cursos. En base a los valores de conductividad eléctrica y RAS obtenidos, se cartografiaron aquellos sectores de la cuenca con calidades de riego similares. De acuerdo a estos resultados se establecieron los tipos de cultivo que podrían regarse teniendo en cuenta el grado de tolerancia de cada uno. Las aguas de los arroyos provenientes del sector de sierra son de muy buena calidad, y no presentan restricciones para casi ningún tipo de cultivos. Aunque de menor aptitud, los cursos de la cuenca media permiten el riego de los principales cultivos de la zona como el trigo, maíz, girasol, soja y sorgo, entre otros. El agua del río Quequén Salado presenta valores de salinidad sólo tolerados por la cebada y algunas pasturas. No obstante, no se recomienda su uso por su elevada sodisidad. Entre los constituyentes secundarios se determinó el contenido de boro, ya que este elemento puede resultar muy tóxico para determinadas especies. No se encontraron concentraciones superiores al límite permisible de 1 mg/ l, pudiéndose mencionar máximos de 0.84 mg/ l en el río Quequén Salado y 0.76 mg/ l en uno de los afluentes principales.

    Full Text Available Temnocephala lamothei n. sp., a commensal of Pomella megastoma (Sowerby, 1825, is described herein from specimens collected at Arroyo Yabotí-Miní (Misiones province, Argentina. Juveniles and adults were removed from the mantle cavity by host relaxation. Distinctive characters of the new species are: non-partitioned intestine; conical cirrus with 1 face flat and another concave; distal area with spines, as evidenced by a strong, oblique sclerotized ring, and 2 rows of long spines, an internal one with long spines arising from base of introvert and an external one arising from distal end of the introvert. The closest species are T. iheringi, T. rochensis and T. haswelli, which are also commensals of mollusc species. The presence of this new species of Temnocephala, and its similarity to the other species that are commensals of molluscan species, suggest the existence of a morphologically homogeneous group.Temnocephala lamothei n. sp., comensal de Pomella megastoma (Sowerby, 1825, se describe para el arroyo Yabotí-Miní, provincia de Misiones, Argentina. Se extrajeron ejemplares juveniles y adultos de la cavidad paleal, por relajación de los hospederos. Las características distintivas de la nueva especie son: intestino no septado, cirro de forma cónica, con una cara plana y otra cóncava, zona distal con espinas evidente por un fuerte anillo oblicuo esclerosado. Dos hileras de espinas se reconocen en el extremo distal, 1 interna de espinas largas, que surge desde la base del introverso, y 1 externa, que surge del extremo distal del mismo. Las especies más semejantes son T. iheringi, T. rochensis y T. haswelli, especies comensales de moluscos con las que es comparada. El hallazgo de esta nueva especie de Temnocephala y sus características semejantes a las restantes especies del género comensales de moluscos, sugieren que las especies conocidas hasta la fecha formen un grupo morfológicamente homogéneo.

  11. Petrography and geochemistry of five granitic plutons from south central Uruguay: contribution to the knowledge of the Piedra Alta terrane

    International Nuclear Information System (INIS)

    Preciozzi, F.

    2005-01-01

    Granitoid rocks in south-central Uruguay are largely concentrated in three east-west trending metamorphic belts, known as (from south to north) the Montevideo Belt, the San José Belt and the Arroyo Grande Belt. These belts are separated from one another by intervening bands of gneisses of granitic composition. The whole assemblage, the gneisses as well as the metamorphic belts and their associated granites, collectively constitute the Piedra Alta Terrane. Five of these granite plutons, two from the San José Belt and three from the Arroyo Grande Belt, have been studied in some detail and the chemical composition of 86 samples (major elements as well as a selected suite of trace elements) have been determined. These data, as well as Rb-Sr isotopic data, show that these plutons are typically composite in nature, and that the various units range in age from 1900 Ma to 2500 Ma. The older ages were obtained from the main units of the plutons themselves whereas the younger ages are from late dykes which were emplaced into the plutons and which are clearly not related to them. The plutons are predominantly, but not exclusively, of calc-alkaline affinity and are typically synorogenic whereas the dykes are post-orogenic and are either calc-alkaline or alkaline in composition. These data have been incorporated into a tectonic model for the Piedra Alta Terrane which is considerably different from that heretofore proposed. The essential features of the geological history of the area are: 1) development of an older ''basement'' of granitic gneisses 2) deposition, upon or adjacent to this gneisses basement, of a typical Archean greenstone belt assemblage (no komatiites so far reported) 3) Paleo-proterozoic metamorphism, followed by syn-tectonic to post-tectonic intrusion of the plutonic rocks 4) major tectonic dislocation(s) associated with the Transamazonian orogeny 5) dyke emplacement (post-orogenic to anorogenic) following the Transamazonian orogeny

    Lexical priming was examined in patients with Alzheimer's disease and in aphasic patients. Control participants were divided into young and elderly [cf. Arroyo-Anlló et al.: Eur J Cogn Psychol 2004;16:535-553]. For lexical priming, a word-stem completion task was used. Normal elderly participants had lexical priming scores that were significantly lower than those of young individuals. Analysis of covariance with age and educational level as covariates showed that the control participants, aphasic and Alzheimer patients did not differ significantly on the lexical priming task. Our results suggest that performance in the lexical priming task diminishes with physiological aging, but is not significantly affected by mild or moderate Alzheimer's disease or by fluent or non-fluent aphasia.

    2003-08-01

    This report provides a survey of remediation and treatment technologies for contaminants of concern at environmental restoration (ER) sites at Sandia National Laboratories, New Mexico. The sites that were evaluated include the Tijeras Arroyo Groundwater, Technical Area V, and Canyons sites. The primary contaminants of concern at these sites include trichloroethylene (TCE), tetrachloroethylene (PCE), and nitrate in groundwater. Due to the low contaminant concentrations (close to regulatory limits) and significant depths to groundwater ({approx}500 feet) at these sites, few in-situ remediation technologies are applicable. The most applicable treatment technologies include monitored natural attenuation and enhanced bioremediation/denitrification to reduce the concentrations of TCE, PCE, and nitrate in the groundwater. Stripping technologies to remove chlorinated solvents and other volatile organic compounds from the vadose zone can also be implemented, if needed.

    Full Text Available AIM: To establish the dynamics of C. furcoides in horizontal and temporal scales; and to determine the main ecological factors related to its dynamics. METHODS: Samples were taken in five stations between July 2002 and July 2003. Physical and chemical variables were sampled monthly. Density was evaluated by sampling carried out within the photic zone. Growth rate (r, Turnover rate (T, Generation Time (gt, Niche Width (NW, Taylor's Power Law, and the rate of population change (σs, were used. Canonical Correspondence Analysis (CCA was used too. RESULTS: Total density was 264163.4 cel.L-1, the highest was found in Up Río Chico and the lowest in Dam. The species was more clustered in space than in time. r ranged between 0.29 and 0.3 cel.d-1, gt between 1.8 and 2.4 days, T between 0.55 and 0.42 divisions per day, NW between 0.58 and 0.72, and σs between 0.3 d-1 and 2.3 d-1. The first three components of CCA explained 92.2% of the variation. Density was positively associated with chlorophyll a, NH4+, RWCS and wind direction. Light attenuation, NO3-, SiO2 and O2 were negatively associated with C. furcoides. DISCUSSION: C. furcoides is a S strategist; it increases its density in the warmest periods under eutrophic conditions, low light penetration and high thermal stability; it is independent of the temperature but dependent of changes in rainfall and nutrients, - especially nitrogen - and not soluble phosphorus. Up Río Chico presented the best conditions for the increase of C. furcoides, since this station presented the highest levels of total nitrogen, and the highest relative stability. CONCLUSION: C. furcoides has a very similar ecology to that of C. hirundinella. It is an organism highly variable in temporal and spatial scales, with a wide niche and a clustered distribution. It belongs to the Morpho-funtional Group V and to Lo and L M Assotiations.OBJETIVO: determinar a dinâmica de C. furcoides em escalas horizontal e temporal, e determinar os

El objetivo de este estudio ha sido conocer el nivel de práctica de actividad física habitual en adolescentes y analizar su influencia en la salud, especialmente cardiovascular. Así como, diseñar y llevar a cabo un programa de intervención de mejora de la condición física y del estilo de vida en esta misma población. Se evaluó, pre-intervención, nivel de práctica de actividad física y tiempo dedicado a actividades sedentarias, mediante cuestionario; y pre- y posintervención, presión arterial y frecuencia cardiaca en reposo, mediante tensiómetro digital; composición corporal, mediante antropometría (peso, talla, pliegues cutáneos y perímetros corporales y la condición física orientada a la salud, mediante ocho pruebas para medir diferentes capacidades (resistencia aeróbica, fuerza y resistencia muscular, flexibilidad y velocidad-agilidad. A partir de las anteriores, se calculó Índice de masa corporal, porcentaje de grasa, masa libre de grasa y capacidad aeróbica. Concluimos que el nivel de práctica de actividad física de los adolescentes residentes en el área metropolitana de Valencia es bajo, asociándose los chicos a un nivel de práctica muy superior al de las chicas (57,6 % de chicos y 14 % de chicas cumplen las recomendaciones al respecto; datos que son preocupantes por las repercusiones que puedan tener en la salud. El sexo tiene una alta influencia en los hábitos de práctica de actividad física, por lo que se debería tener muy en cuenta a la hora de diseñar y llevar a cabo programas de intervención.

La mayoría de los estudios acerca de estos fenómenos se han llevado a cabo en países occidentales, siendo mucho menos común la investigación en países asiáticos. Nosotros damos cuenta de un sondeo realizado entre 1.049 estudiantes (con un 42% de chicos y un 58% de chicas de edades comprendidas entre los 12 y los 18 años, en 12 centros educativos de 3 provincias del sur de Tailandia, sobre las experiencias relacionadas con haber sido víctimas del acoso tradicional y el ciberacoso en los dos meses anteriores, y sobre las estrategias de afrontamiento más recomendables. Decírselo a un docente o a uno de los padres era la estrategia que más se aconsejaba en el caso de la victimización tradicional; esto no ocurría en la misma medida cuando se trataba de la cibervictimización, donde lo más recomendado era bloquear mensajes/identidades o cambiar la dirección de correo electrónico o el número de teléfono. Los alumnos más mayores eran más proclives a aconsejar denunciar ante la policía y llevar un registro de los incidentes de acoso. Existían grandes diferencias de género, con las chicas recomendando que se contara y se denunciara más, tanto para el acoso tradicional como para la cibervictimización. Las chicas también aconsejaban ignorar el acoso con más frecuencia o bloquear los mensajes; mientras que los chicos recomendaban defenderse, pero también hacer nuevos amigos. Había pocas diferencias por motivo de religión. Las víctimas mostraban una mayor propensión a recomendar estrategias pasivas tales como evitar a los acosadores, o estrategias arriesgadas como defenderse. Se analizan los hallazgos con respecto a la investigación realizada anteriormente y las implicaciones para el trabajo anti-acoso en las escuelas.

    The active shield-volcano Sierra Negra is part of the Galapagos hotspot. Sierra Negra is the largest shield volcano of Isabela Island, hosting a 10 km diameter caldera. Ten historic eruptions have occurred and some involved a frequently visited east caldera rim fissure zone called Volcan Chico. The last volcanic event occurred in October 2005 and lasted for about a week, covering approximately twenty percent of the eastern caldera floor. Sierra Negra volcano has experienced some significant changes in the chemical composition of its volcanic gas discharges after the 2005 eruption. This volcanic event produced an important SO2 degassing that depleted the magmatic content of this gas. Not significant changes in the MORB and plume-type helium contribution were observed after the 2005 eruption, with a 65.5 % of MORB and 35.5 % of plume contribution. In 2006 a visible and diffuse gas emission study was performed at the summit of Sierra Negra volcano, Galapagos, to evaluate degassing rate from this volcanic system. Diffuse degassing at Sierra Negra was mainly confined in three different DDS: Volcan Chico, the southern inner margin of the caldera, and Mina Azufral. These areas showed also visible degassing, which indicates highly fractured areas where volcano-hydrothermal fluids migrate towards surface. A total fumarole/plume SO2 emission of 11 ± 2 td-1 was calculated by mini-DOAS ground-based measurements at Mina Azufral fumarolic area. Molar ratios of major volcanic gas components were also measured in-situ at Mina Azufral with a portable multisensor. The results showed H2S/SO2, CO2/SO2 and H2O/SO2 molar ratios of 0.41, 52.2 and 867.9, respectively. Multiplying the observed SO2 emission rate times the observed (gas)i/SO2 mass ratio we have estimated other volatiles emission rates. The results showed that H2O, CO2 and H2S emission rates from Sierra Negra are 562, 394, and 2.4 t d-1, respectively. The estimated total output of diffuse CO2 emission from the summit of

    The Ag contents of abiotic and biotic compartments of different lakes of Nahuel Huapi National Park, Patagonia, Argentina were analyzed. The water bodies studied were lakes Nahuel Huapi, Moreno, Escondido, Espejo Chico and Traful, the latter chosen as a reference lake. The Ag concentration profiles of short sediment cores, dated by 210 Pb and 137 Cs techniques, were analyzed, as well as suspended load collected from three sites of lake Nahuel Huapi. The biota studied were the native mussel Diplodon chilensis (digestive gland and total soft tissues pooled samples) and five species of fish, two native and three introduced (liver and muscle pooled samples). Ag contents were determined by Instrumental Neutron Activation Analysis (INAA). The upper layers of the sediment cores sampled in lake Nahuel Huapi were enriched in Ag contents compared to deep layers in accumulation periods corresponding to the second half of the 20th century, but this enrichment was neither observed in the reference lake Traful, nor in lakes Espejo Chico and Escondido. Ag was enriched over background level (0.1 μg g -1 ) also in suspended load collected in lake Nahuel Huapi. Ag fluxes to sediments were computed for suspended load and enriched sediment core layers. Highest Ag fluxes, from 350 to 470 μg m -2 year -1 , were measured in Nahuel Huapi near the site where the liquid effluents of the Bariloche city sewage treatment plant are released to the lake. The spatial distribution of the other Ag fluxes suggests that this is the main source of Ag to lake Nahuel Huapi and lateral transport occurs within the water body. Ag concentrations on biota samples were consistent with these conclusions. Mussels collected in lake Nahuel Huapi showed higher Ag concentrations than in the other lakes, especially when compared to lake Traful. Ag contents in mussels were strongly associated with sediment intake, but enriched probably due to sediment grain size sorting during the intake processes. Evidence of food

    In the immediate vicinity of Santofirme, 16 km south-east of Oviedo, there is an 18 km/sup 2/ outcrop of material from the Carboniferous period which forms a syncline running north-east to south-west and which, in places, is covered with Permo-Triassic and Tertiary material from the Depresion de Llanera. The series consists of regularly alternating layers of lutite and sandstone with bands of coal and a few lime bands in the lower section. Twenty-one of the coal bands, grouped together in eight packets, are worked by Minas de Villabona SA. All the coal bands in the western flank of the syncline have been tested. Most of the samples were collected from four drillings carried out by ENADIMSA in 1982; those remaining were taken from the surface at the Arroyo Socavon and La Tejera opencast sites.

    The “Colonia Shear Zone System”, characterized by a transcurrent system of predominant sinistral shear sense, is defined by two approximately parallel shear zones, denominated Isla San Gabriel-Juan Lacaze Shear Zone (ISG-JL S.Z.) and Islas de Hornos-Arroyo Riachuelo Shear Zone (IH-AºR S. Z.). Represented by rocks with ductile and brittle deformation, are defined as a strike slip fault system, with dominant subvertical foliation orientations: 090-100º (dip-direction 190º) and 090-100º (dip-direction 005º). The K/Ar geochronology realized, considering the estimates temperatures conditions for shear zones (450-550º), indicate that 1780-1812 Ma should be considered a cooling age and therefore a minimum deformation age. The observed microstructures suggest deformation conditions with temperatures between 450-550º overprinted by cataclastic flow structures (reactivation at lower temperature)

    Full Text Available The paper looks into the most successful horror franchise in Philippine history. Shake, Rattle and Roll has had a successful 14-film run since its introduction in 1984, and is composed of a three-part segment, each tackling a horrific experience: ghosts and folk creatures in provincial and city settings. My paper maps out the narratives, and the social and political contexts of the series. Specif ically, the period beginning 1984 marks a series of national transition: the political crisis of the Marcoses, People Power 1, the rise of Corazon Aquino, the economic crises in 1997 and 2007, the ousting of Joseph Estrada, the rise of neoliberalism, the coming of Noynoy Aquino, and the incarceration of Gloria Arroyo. How might these films also be read as analog of the anxieties of the nation?

    The dracunculoid nematode Mexiconema cichlasomae Moravec, Vidal et Salgado Maldonado, 1992, originally described from the abdominal cavity and viscera of Cichlasoma spp. from Mexico, was recorded from the abdominal cavity of the poeciliid Xiphophorus helleri Heckel in Lake Catemaco and its small tributary Arroyo Agrio, Veracruz and from the intestine of the nurse shark Ginglystoma cirratum (Bonnaterre) off the southern coast of the Gulf of Mexico in Campeche; both these findings represent new host records. The nematode specimens from these hosts are briefly described and illustrated. Whereas X. helleri evidently served as the true definitive host of this parasite, G. cirratum probably acquired Mexiconema infection accidentally while feeding on fish definitive hosts in the brackish or salt-water environment. The ability of M. cichlasomae to utilize fishes of different orders (Perciformes and Cyprinodontiformes) as definitive hosts is rather exceptional among dracunculoid nematodes.

    Full Text Available Desde la década de 1880, es posible distinguir en las provincias de Atacama y Coquimbo una aguda decadencia económica y social, debido fundamentalmente a la crisis de su principal actividad exportadora, la minería. Esto tuvo su correspondencia en el ámbito político nacional, donde el impacto real de estas provincias se vio seriamente disminuido en comparación a su activo protagonismo de mediados de siglo. Este trabajo analiza, a través de coyunturas específicas, los aspectos más importantes de la “decadencia política”, enfatizando en la huelga general de 1890, la guerra civil de 1891, la violencia social y las peticiones por políticas públicas a fin de superar la crisis de estos espacios nacionales.

    Full text: ''Chico'' is an early maturing (85-90 days) erect groundnut (Arachis hypogaea L.) genotype utilised in groundnut improvement to incorporate earliness in high yielding varieties. Though it has high shelling out-turn, its yield potential is low since it has small seeds. Mutation breeding was started with the objective of improving the seed size. In a preliminary experiment, dry seeds were treated with 20, 30, 40 or 50 kR of gamma rays. The M 1 generation was grown during the post rainy season of 1988-1989. The M 2 generation was planted as individual plant progeny rows during the rainy season of 1989. 105 progeny rows were studied, the total number of M 2 plants being 1,730. All the M 2 plants were harvested 90 days after sowing. Seven mutants with bold seed size were obtained. The mutants had 100 kernel weight ranging from 22.2 to 40.4 g compared to 21.1 g of control. The study is in progress. (author)

    Full Text Available El sentido de la educación está en posibilitar que cada chica, cada chico, vayan encontrando referentes para ser libres, conociéndose a sí mismos y al mundo. Para ello es necesario reconocer, y traducir en prácticas, la singularidad irreductible de quienes somos: hombres y mujeres. De no hacerlo, se corre el riesgo de privar a las mujeres de los referentes de autoridad femenina que les son necesarios para saber quiénes son, para dar contenido a su libertad. El énfasis en la igualdad de derechos y en la emancipación es importante para eliminar desigualdades pero no es suficiente, ni equivalente, a generar posibilidades de libertad femenina (y masculina. Para ayudarnos en esta tarea disponemos de conocimientos y de prácticas que nos ofrecen referentes de autoridad para enseñar la libertad a las niñas y a las mujeres en la escuela.

    Full Text Available Este trabalho expõe uma interpretação das categoriais sociais representativas no Brasil na década de 1970, retratadas em cinco canções de Chico Buarque de Hollanda na peça Ópera do malandro. Procuramos demonstrar, a partir dos exemplos musicais propostos, que Hollanda fez da relação tensa entre censura e produção artística a base de sua matéria poética, imprimindo um sentido político-social original em sua obra musical, indo além dos limites da canção de protesto tradicional. Essa opção do autor teve como base a proposta teórico-prática do dramaturgo e teórico alemão Bertolt Brecht, que, em seus escritos sobre ópera, defende uma maior independência da música com relação à ação dramática.

    JURACY ASSMANN SARAIVA

    Full Text Available Resumo Partindo do pressuposto de que a memória é um dos fundamentos da literatura, o artigo compara Leite derramado, de Chico Buarque, com Memórias póstumas de Brás Cubas, de Machado de Assis. A análise explicita semelhanças e diferenças entre esses romances memorialísticos, relativas a aspectos temáticos e composicionais, e comprova que ambos compõem uma alegoria da nacionalidade brasileira, estabelecendo um paralelismo entre o percurso da vida dos protagonistas, ou de sua família, e episódios da história do Brasil. Conclui que os procedimentos criativos das narrativas compõem um jogo de espelhos que, ao envolver o leitor, reivindica a importância da literatura como espaço de reflexão sobre si mesma e sobre acontecimentos da história, os quais a ficção projeta sob nova luz.

    2013-12-01

    Full Text Available In this article we retrieve the history of environmental education in public environmental management, in the period between the creation of the Chico Mendes Institute for Biodiversity Conservation (ICMBio, in 2007, and the time it institutionalized and consolidated environmental education in 2012, aiming at demonstrating the political and ideological issues in dispute in the process of institutionalization of the field, focusing on an institute dedicated to the conservation of biodiversity after the splitting of IBAMA. For this purpose, we performed the analysis of federal official documents and testimonials from protagonists of that period. Finally, we concluded that the consolidation process of education in the process of environmental management at the federal agency has been restructured, not without tensions and institutional contradictions, rebuilding an activity that was institutionally interrupted in the process of creating the ICMBio, and which is fundamental to the fight for environmental justice and overcoming the social conservation-justice dichotomy in Brazil.

    Rural communities in the Haut-Uele Province of northern Democratic Republic of Congo live in constant danger of attack and/or abduction by units of the Lord's Resistance Army operating in the region. This pilot study sought to develop and evaluate a community-participative psychosocial intervention involving life skills and relaxation training and Mobile Cinema screenings with this war-affected population living under current threat. 159 war-affected children and young people (aged 7-18) from the villages of Kiliwa and Li-May in north-eastern DR Congo took part in this study. In total, 22% of participants had been abduction previously while 73% had a family member abducted. Symptoms of post-traumatic stress reactions, internalising problems, conduct problems and pro-social behaviour were assessed by blinded interviewers at pre- and post-intervention and at 3-month follow-up. Participants were randomised (with an accompanying caregiver) to 8 sessions of a group-based, community-participative, psychosocial intervention (n=79) carried out by supervised local, lay facilitators or a wait-list control group (n=80). Average seminar attendance rates were high: 88% for participants and 84% for caregivers. Drop-out was low: 97% of participants were assessed at post-intervention and 88% at 3 month follow-up. At post-test, participants reported significantly fewer symptoms of post-traumatic stress reactions compared to controls (Cohen's d=0.40). At 3 month follow up, large improvements in internalising symptoms and moderate improvements in pro-social scores were reported, with caregivers noting a moderate to large decline in conduct problems among the young people.

    Since 1996 Bossi and Pineyro proposed the posibility of subhorizontal contacts between Piedra Alta geological units with very different metamorphic grade and lithological associations. The idea was discarded in an itinerant workshop because of lacking of mylonites in the proposed planes containing pegmatites and/or muscovite granites of very low dipping. The possibility that peraluminous magma acted as a lubricant and allow significant movements without great efforts led to rework the topic, utilizing 850 observations of the Vulcanitas Arqueanas Project and 750 observations of the Terreno Piedra Alta Project Georeferenced observations were located on 1:50,000 topographic maps and areas with higher density were aerophotointerpreted at 1:40,000 scale and geologically surveyed at different scales.The thrust-fault of Florida granite belt over San Jose belt was confirmed, and a new thrust-fault was found in the Arroyo Castro valley with 2% dipping to the north

    Six helminth species were recorded during the helminthological examination of 35 specimens of the goodeid Xenotaenia resolanae from Arroyo Durazno, Jalisco, Mexico, a tributary of the Cuzalapa River. Helminth species identified included: 4 species of digeneans, i.e., Posthodiplostomum minimum (metacercariae), Clinostomum companatum (metacercariae), Dendrorchis sp. (adult), and Margotrema guillerminae (adult); and 2 species of nematodes, i.e., Spiroxys sp. (larvae) and Rhabdochona ahuehuellensis (adult). A very low number of individual larvae were found. The observed species richness, individual parasite abundance, and diversity were low at both component community and infracommunity levels. The values of similarity between infracommunities were relatively high because of the predominance of the digenean M. guillerminae, the species that reached the higher values of both prevalence and abundance. High water flow of the collecting site is suggested as the main factor determining the depauperate helminth assemblage in this fish species.

    Facial / microfacial studies and geochemical isotopic analyses on marine jurassic carbonates of the Calabozo Formation (Dessanti, 1973) were carried out to reconstruct the palaeoenvironment and postdepositional history of the unit. This study is part of a project which purpose is the sedimentological and geochemical characterization of the Jurassic carbonate sequences of Cuenca Neuquina, in the southwestern Mendoza, Argentina. A detailed description about this basin can be found in Legarreta and Uliana (1999) and Riccardi et al. (2000). During the Late Bathonian and Early Callovian, the basin showed a reduction of the sedimentation area and a marked marginal facies progradation. West of Malargue, in areas with low detritic contribution, limestones of the Calabozo Formation were deposited. At the end of the Early Callovian, the basin was isolated, prevailing hypersaline conditions which caused the accumulation of the evaporites of the Tabanos Formation (Stipanicic, 1966) (au)

    Full Text Available Rivers are natural, dynamic and complex systems. Its main function is the transportation of water, sediments and nutrients, conforming areas of great ecological and territorial value. Morphology varies according to the structure and the drainage network. Fluvial systems typification classifies and characterize rivers in order to provide substantial information about every section. Although there are several classifications and characterizations, Rosgen’s combines hydrological, geomorphological and ecological aspects that serves as important indicators towards this study. River classifications are relevant to understanding natural systems and their function, being an instrument of major importance in territorial planning, which provides a significant benefit to environment and society. The area encloses the lower basin of El Negro stream in Sierra de la Ventana, Argentina. Thehomonym village occupies part of the floodplain of the main channel. In recent years, the real estate pressure in these areas led to the opening of new subdivisions for the construction of resorts, changing the stream morphology. The aim of this work is to morphologically characterize and typify a section located in the lower basin of El Negro stream to generate a methodology applicable to other courses in the sector. Before typification, sectioning was implemented following criteria by Ollero Ojeda y otros (2003 and utilizing aerial photographs. The corresponding portion of the lower basin was selected for morphological characterization as the one showing major changes due to being in the urbanized area. The investigation was done based on Thorne’s methodology (1998, and afterwards typified following Rosgen’s criteria (1994. The typification resulted in a A3 stream category based on its morphological characteristics. The methodology allows to comprehend fluvial dynamics and gather data from a sector where scarces or nonexists, in order to generate representative information about hydrogeomorphological conditions that may be taken into account by authorities.

    1998-06-01

    A multiple Robertsonian fission chromosomal race of the Liolaemus monticola complex in Chile is described and is shown to be the most derived and the most complex among the Liolaemus examined thus far. The 29 karyotyped lizards analysed from the locality of Mina Hierro Viejo, Petorca, Provincia de Valparaiso, Chile, exhibited a diploid chromosomal number ranging from 42 to 44, and several polymorphisms. The polymorphisms included: a pair 1 fission; a pair 2 fission plus a pericentric inversion in one of the fission products, which moved the NOR and satellite from the tip of the long arm of the metacentric 2 to the short arm of the fission product; a fission in pair 3; a polymorphism for an enlarged chromosome pair 6; and a polymorphism for a pericentric inversion in pair 7. This population is fixed for a fission of chromosome pair 4. A total of 76% of the lizards analysed were polymorphic for one or more pairs of chromosomes. We have compared these data with other Liolaemus monticola chromosomal races and calculated the Hardy-Weinberg ratios for the polymorphic chromosome pairs in this Multiple-Fission race. Karyotypic differences between the Northern (2n = 38-40) and the Multiple-Fission (2n = 42-44) races were attributed mainly to Robertsonian fissions, an enlarged chromosome and pericentric inversions involving the macrochromosomes and one microchromosome pair.

    The Ag contents of abiotic and biotic compartments of different lakes of Nahuel Huapi National Park, Patagonia, Argentina were analyzed. The water bodies studied were lakes Nahuel Huapi, Moreno, Escondido, Espejo Chico and Traful, the latter chosen as a reference lake. The Ag concentration profiles of short sediment cores, dated by {sup 210}Pb and {sup 137}Cs techniques, were analyzed, as well as suspended load collected from three sites of lake Nahuel Huapi. The biota studied were the native mussel Diplodon chilensis (digestive gland and total soft tissues pooled samples) and five species of fish, two native and three introduced (liver and muscle pooled samples). Ag contents were determined by Instrumental Neutron Activation Analysis (INAA). The upper layers of the sediment cores sampled in lake Nahuel Huapi were enriched in Ag contents compared to deep layers in accumulation periods corresponding to the second half of the 20th century, but this enrichment was neither observed in the reference lake Traful, nor in lakes Espejo Chico and Escondido. Ag was enriched over background level (0.1 {mu}g g{sup -1}) also in suspended load collected in lake Nahuel Huapi. Ag fluxes to sediments were computed for suspended load and enriched sediment core layers. Highest Ag fluxes, from 350 to 470 {mu}g m{sup -2} year{sup -1}, were measured in Nahuel Huapi near the site where the liquid effluents of the Bariloche city sewage treatment plant are released to the lake. The spatial distribution of the other Ag fluxes suggests that this is the main source of Ag to lake Nahuel Huapi and lateral transport occurs within the water body. Ag concentrations on biota samples were consistent with these conclusions. Mussels collected in lake Nahuel Huapi showed higher Ag concentrations than in the other lakes, especially when compared to lake Traful. Ag contents in mussels were strongly associated with sediment intake, but enriched probably due to sediment grain size sorting during the intake

    Full Text Available O objetivo do trabalho foi avaliar a não-preferência para alimentação de lagartas de 1o e de 5o ínstares, de Spodoptera frugiperda, em quatro genótipos de milho: IAC701 N, 'IAC7777', Mp707 e Zapalote Chico (ZC. Os ensaios foram realizados em arenas, com livre chance de escolha pelas lagartas, por 24 horas. Com lagartas recém-eclodidas, 1o ínstar, observou-se não-preferência ao ZC e Mp707, nos quais se encontraram apenas 20% das lagartas, em comparação com IAC701 N e 'IAC7777', onde se concentraram 80% delas. No teste com lagartas de 5o ínstar, o consumo das seções foliares foi cerca de duas vezes maior em `IAC701 N, se comparado a `ZC' e `Mp707'. Concluiu-se que a antixenose ou não-preferência é um dos mecanismos de resistência encontrados em ZC e Mp707, materiais estrangeiros que confirmam, nas condições de Campinas, suas características de resistência.The effect of corn genotypes upon food preferences of Spodoptera frugiperda larvae was evaluated. The genotypes selected were: IAC701 N, an inbred line of Instituto Agronômico de Campinas (IAC, State of São Paulo, Brazil; 'IAC7777', a single hybrid of IAC in which the above inbred line is one of the parents; Mp707, an inbred line of Mississippi State University considered to be resistant to S. frugiperda; and Zapalote Chico (ZC, a Central American corn race referred as resistant to Helicoverpa zea and S. frugiperda. The tests were run in arenas with free choice among treatments. The test with 1st instar larvae indicated that the insects preferred to feed on the genotypes IAC701 N and IAC7777, and a lower percentage of larvae stablished on the leaves of ZC and Mp707. The test with 5th instar larvae indicated a non-preference of the larvae for the leaves of genotypes Mp707 and ZC while IAC701 N was the most preferred with more leaf area consumed. The non-preference for feeding tests leaded to the conclusion that this type of resistance is present in ZC and Mp707. These

    Full Text Available El objetivo de este artículo es analizar los tipos de comportamiento y las opiniones según los jóvenes españoles sobre la salud y sus determinantes, en función de la edad, el sexo y el ámbito de residencia. Los jóvenes españoles tienen un concepto amplio de su salud, física y emocional, e identifican lo sano con la buena alimentación y la actividad física. La mayoría de ellos (91% perciben su salud como buena o muy buena. El problema de salud que los jóvenes identifican en primer lugar son las drogas. Según la edad, el sexo y el lugar de residencia, entre el 10 y el 20% podría tener algún problema de salud mental. Los chicos presentan prevalencias de sobrepeso más elevadas que las chicas; éstas se perciben a sí mismas más obesas de lo que realmente están y a ellos les sucede lo contrario. La práctica deportiva decae a partir de los 15 años, tanto en chicas como en chicos. La familia y los amigos desempeñan un papel importante en la actividad física. Perciben el consumo de hachís como normal, pero mantienen una actitud ambivalente ante otras sustancias ilegales y demandan más información sobre todas las drogas. Se observa una alta proporción de jóvenes que no probarían drogas ilegales. El consumo de tabaco es superior en las chicas que en los chicos en el medio urbano, pero en el medio rural predomina el consumo en los hombres. La mayoría sabe que el tabaco perjudica su salud y casi la mitad de los mayores de 18 años que fuman quieren dejarlo. Consideran que los servicios sanitarios son poco útiles para prevenir los problemas de salud. El uso del casco y el cinturón de seguridad son mejorables, especialmente en el medio rural. Los jóvenes relacionan los accidentes de tráfico con el contexto en el que se conduce y con la falta de identificación del riesgo.The objective of this article is to analyse different behaviours and opinions about health and health determinants of Spanish young people by age, sex, and

    Two Steinernema isolates found in Louisiana and Mississippi were later identified as isolates of S. rarum. DNA sequences of ITS regions of the United States isolates are identical with sequences of Argentinean S. rarum strains Samiento and Noetinger and differ by two bases from the Arroyo Cabral isolate from Córdoba, Argentina. SEM observations revealed several new structures in the isolates from the US: female face views have a hexagonal-star perioral disc and eye-shaped lips; some females do not have cephalic papillae; lateral fields of infective juveniles are variable; there are two openings observed close to the posterior edge of the cloaca. Virulence of the US isolates to Anthonomus grandis, Diaprepes abbreviatus, Solenopsis invicta, Coptotermes formosanus, Agrotis ipsilon, Spodoptera frugiperda, and Trichoplusia ni and reproductive potential were evaluated in comparison with other heterorhabditid and steinernematid nematodes. Results such as particularly high virulence to S. frugiperda indicate that the biocontrol potential of the new S. rarum strains merits further study. PMID:19259427

  2. On two populations of sunspot groups

    1980-01-01

    The principal component method was applied studying the sunspot groups distribution in respect to the maximum area for the individual 11-year cycles 12 to 19 (Lopez Arroyo and Lahulla, 1974) and for the years 1900 to 1964 (Mandrykina, 1974). The existence of two populations of sunspot groups is confirmed. The variations of the importance parameter q, which determines the population shares, in the 80-, 22- and 11-year cycles are considered. The obtained maximal area distributions for populations I and II are approximated by linear combination of logarithmic-normal distributions, the subpopulations Ia, Ib, Ic by the most probable maximum areas of 22, 298 and 90 mvh, respectively, and the subpopulations IIa, IIb, IIc by the most probable maximal areas of 6, 142 and 754 mvh, respectively. The characteristic distinction between populations I and II is apparently the magnetic structure of the groups belonging to them (bipolar and unipolar ones). (author)

  3. Application of a health risk assessment model for cattle exposed to pesticides in contaminated drinking waters: A study case from the Pampas region, Argentina.

    Using the USEPA methodology we estimated the probabilistic chronic risks for calves and adult cows due to pesticide exposure through oral intake of contaminated surface and ground waters in Tres Arroyos County (Argentina). Because published data on pesticide toxicity endpoints for cows are scarce, we used threshold levels based on interspecies extrapolation methods. The studied waters showed acceptable quality for cattle production since none of the pesticides were present at high-enough concentrations to potentially affect cow health. Moreover, ground waters had better quality than surface waters, with dieldrin and deltamethrin being the pesticides associated with the highest risk values in the former and the latter water compartments, respectively. Our study presents a novel use of the USEPA risk methodology proving it is useful for water quality evaluation in terms of pesticide toxicity for cattle production. This approach represents an alternative tool for water quality management in the absence of specific cattle pesticide regulatory limits. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2008-01-01

    Traumatic injury of the abdominal aorta is rare and potentially lethal (Yeh et al., J Vasc Surg 42(5):1007-1009, 2005; Chicos et al., Chirurgia (Bucur) 102(2):237-240, 2007) as it can result in major retroperitoneal hemorrhage, requiring an urgent open surgery. In case of concomitant bowel injury or other conditions of hostile abdomen, endovascular repair can be an alternative treatment. This case report deals with a 50-year-old man presenting at the emergency ward with three stab wounds: two in the abdomen and one in the chest. During explorative laparotomy, liver laceration and bowel perforation were repaired. One day later, abdominal CT-scan revealed an additional retroperitoneal hematoma associated with an aortic pseudoaneurysm, located anteriorly 3 cm above the aortic bifurcation. Because of the risk of graft infection, an endovascular repair of the aortic injury using a Gore excluder stent-graft was performed. Radiological and clinical follow-up revealed a gradual shrinkage of the pseudo-aneurysm and no sign of graft infection at two years' follow-up.

    Full Text Available Este artículo examina la red de prácticas que confieren inteligibilidad a la organización del conocimiento de las materias escolares que hace PISA. El programa PISA es tratado como un acontecimiento histórico. Su estudio consiste en hacer visible los principios que ordenan y clasifican los objetos “vistos” y que actúan sobre el “conocimiento práctico” de las materias escolares. La política de PISA, a mi juicio, son los principios que rigen lo que los chicos deberían conocer, cómo ese conocimiento se hace posible, y el estudio de la inclusión y exclusión incorporadas en estas prácticas. La primera parte analiza históricamente la transformación de los números en “hechos”, una presunción que posibilita las comparaciones de PISA. En la segunda parte, dirige la atención a los principios de las materias escolares que ordenan y clasifican los “hechos” de las mediciones de PISA.

Though it has high shelling out-turn, its yield potential is low since it has small seeds. Mutation breeding was started with the objective of improving the seed size. In a preliminary experiment, dry seeds were treated with 20, 30, 40 or 50 kR of gamma rays. The M{sub 1} generation was grown during the post rainy season of 1988-1989. The M{sub 2} generation was planted as individual plant progeny rows during the rainy season of 1989. 105 progeny rows were studied, the total number of M{sub 2} plants being 1,730. All the M{sub 2} plants were harvested 90 days after sowing. Seven mutants with bold seed size were obtained. The mutants had 100 kernel weight ranging from 22.2 to 40.4 g compared to 21.1 g of control. The study is in progress. (author)

    2010-04-01

    The northernmost known breeding population of jaguars occurs in the municipality of Nácori Chico, Sonora, Mexico about 270 km from the United States-Mexico border and may be the source from which jaguars sighted in the United States dispersed. Since 1999 at least 11 jaguars (Panthera onca) had been illegally killed in the area due to predator control programs. We initiated a jaguar landowner-based conservation plan in 2004. The eight participating landowners agreed to suspend predator control programs targeting jaguars and pumas (Puma concolor) only if cattle losses were compensated. A private outfitter, with the consent of landowners, initiated white-tailed deer (Odocoileus virginianus) hunts in 2004 and agreed to pay the group of participating landowners US$1500 for every deer hunt permit sold. The funds paid to the landowners from deer hunts were sufficient to convince landowners to suspend all predator-control efforts of jaguars and pumas. The involvement of landowners in the jaguar conservation program in northeastern Sonora is a successful, private, wildlife-conservation initiative that provides an example for jaguar conservation efforts in northern Mexico.

    Recent Coulomb excitation studies on 144,146Ba using the GRETINA-CHICO2 detection system with post-accelerated CARIBU beams have confirmed the existence of enhanced E3 transitions in these isotopes which are centered in a region that has long been predicted to exhibit stable octupole-deformed shapes. Furthermore, the widely-varying E1 strength observed between these isotopes is well-accounted for by models having octupole-deformed potentials, and the variation has been linked to increased occupancies of specific single-particle orbitals in the reflection-asymmetric potential. This talk will summarize the most recent experimental and theoretical results. In addition, data on octupole-related properties in the surrounding isotopes will be discussed in an attempt to better understand the origin and evolution of octupole collectivity in this mass region.

The first step was the geographical location of the voluntary delivery points and check the current collection - verifying collected and route volume. The second step was to propose routes and the third step was the comparison between the performed route and the proposal route. By comparing the route performed by empirical method and the computational method, we came to 12.76% by reducing distances. The question regarding the volume of collected organic waste, we have identified that reducing the 50 liters container volume to 30 liters, reduces the route.

    Full Text Available Armadillos of the species Dasypus novemcinctus and Euphractus sexcintus are xenarthrico is a mammal that inhabits fields and has several eating habits. This study proposes to analise the macroscopic anatomy of the nervous system of the armadillo peba, enabling comparisons with other mammals. Three animals of each species were to donated ICMBio - Chico Mendes Institute for Biodiversity, the Serra da Capivara National Park, authorized by SISBIO 22826-01, victims of poaching and they had died. The animals were stored in Histology and Embryology Laboratory of the Morphology Department of Health Sciences Center of the Federal University of Piauí. Initially, they were fixed with 10% buffered formalin for 24 hours and then dissected for observation of the organs forming the central nervous system. The central nervous system Armadillo consists of the brain and spinal cord. The macroscopic morphology, the central nervous system Armadillo resembles those of other mammals, however, anatomical features found in the brain and spinal cord suggest a higher olfactory expression and motor skills.

    Full Text Available This work has been awarded a prize by the Prestreesed Concrete Institute. It refers to a number of flyovers on the Arroyo Seco, of California. This river has been canalized, to help drainage in case of heavy rainfall. The canal runs through a highly populated zone, and a motor road and accessory ramps had to cross the canal. The resulting design involves three prestressed girders, lightly arched in a parabolic outline, resting on each river shore, running along the line of the bridge, over the canal. It was decided that the bridge piles should not rest on the river bed, in order not to reduce its flow capacity. The girders of a maximum length of 39 ms, are box shaped, and stiffened with thin diaphragms. The cylindrical pile, 1.50 m in diameter, is an integral part of the girder, and applies to it a concentrated load of about 4000 tons. The girders rest on reinforced concrete cubes, which in turn are supported by concrete slabs and piles driven into the soil.Esta obra ha sido premiada por el Prestressed Concrete Institute y se refiere a una serie de pasos superiores sobre el Arroyo Seco, en California, que se ha canalizado para servir de desagüe en el caso de avenidas torrenciales. El canal se halla en una zona de edificación densa y se trata del paso—sobre aquél—de una autopista y rampas de acceso. La solución adoptada consistió en tres vigas pretensadas, ligeramente arqueadas con perfil parabólico, apoyadas en las dos márgenes y situadas en correspondencia con los tres soportes, sobre el propio canal, ya que ninguno de aquéllos debía apoyarse en el lecho de este último al objeto de no disminuir su capacidad de desagüe. Las vigas—de unos 39 m de longitud la mayor—son del tipo cajón, rigidizadas con unos diafragmas de pequeño espesor. El soporte cilíndrico, de 1,50 m de diámetro, se solidariza con la viga y le transmite una notable carga concentrada, del orden de 4.000 toneladas. Los apoyos de estas vigas son simples dados

    Variations in rock magnetic properties are responsible for the many linear, short-wavelength, low-amplitude magnetic anomalies that are spatially associated with faults that cut Neogene basin sediments in the Rio Grande rift, including the San Ysidro normal fault, which is well exposed in the northern part of the Albuquerque Basin. Magnetic-susceptibility measurements from 310 sites distributed through a 1200-m-thick composite section of rift-filling sediments of the Santa Fe Group and prerift Eocene and Cretaceous sedimentary rocks document large variations of magnetic properties juxtaposed by the San Ysidro fault. Mean volume magnetic susceptibilities generally increase upsection through eight map units: from 1.7 to 2.2E-4 in the prerift Eocene and Cretaceous rocks to 9.9E-4-1.2E-3 in three members of the Miocene Zia Formation of the Santa Fe Group to 1.5E-3-3.5E-3 in three members of the Miocene-Pleistocene Arroyo Ojito Formation of the Santa Fe Group. Rock magnetic measurements and petrography indicate that the amount of detrital magnetite and its variable oxidation to maghemite and hematite within the Santa Fe Group sediments are the predominant controls of their magnetic property variations. Magnetic susceptibility increases progressively with sediment grain size within the members of the Arroyo Ojito Formation (deposited in fluvial environments) but within members of the Zia Formation (deposited in mostly eolian environments) reaches highest values in fine to medium sands. Partial oxidation of detrital magnetite is spatially associated with calcite cementation in the Santa Fe Group. Both oxidation and cementation probably reflect past flow of groundwater through permeable zones. Magnetic models for geologic cross sections that incorporate mean magnetic susceptibilities for the different stratigraphic units mimic the aeromagnetic profiles across the San Ysidro fault and demonstrate that the stratigraphic level of dominant magnetic contrast changes with

    Space conditioning represents nearly 50% of average residential household energy consumption, highlighting the need to identify alternative cost-effective, energy-efficient cooling and heating strategies. As homes are better built, there is an increasing need for strategies that are particularly well suited for high performance, low load homes. ARBI researchers worked with two test homes in hot-dry climates to evaluate the in-situ performance of air-to-water heat pump (AWHP) systems, an energy efficient space conditioning solution designed to cost-effectively provide comfort in homes with efficient, safe, and durable operation. Two monitoring projects of test houses in hot-dry climates were initiated in 2010 to test this system. Both systems were fully instrumented and have been monitored over one year to capture complete performance data over the cooling and heating seasons. Results are used to quantify energy savings, cost-effectiveness, and system performance using different operating modes and strategies. A calibrated TRNSYS model was developed and used to evaluate performance in various climate regions. This strategy is most effective in tight, insulated homes with high levels of thermal mass (i.e. exposed slab floors).

Los ambientes dulceacuicolas de esta area estan bajo amenaza por peces exoticos, eutrofizacion y plaguicidas, entre otros problemas. Este IBI debe permitir identificar los sitios mas vulnerables y, eventualmente, guiar los esfuerzos de rehabilitacion. Se evaluaron datos de composicion, estructura y funcion de las comunidades de peces. Se exploraron 23 sitios en la parte mexicana de la cuenca; se uso una submuestra estratificada de 13 sitios para disenar el IBI y el resto para probarlo y refinarlo. Se busco la correlacion de 34 posibles metricos con un indice de calidad del agua y ambiente, asi como con la posible influencia de la anchura del arroyo y la altitud y distancia al cauce principal del rio Hondo. Se seleccionaron doce metricos para constituir el IBI: las abundancias relativas de Astyanax aeneus, 'Cichlasoma' urophthalmus, Poecilia mexicana, Poecilia sp.

    This report describes environmental work performed at the Device Assembly Facility (DAF) in 1994 by the Basic Environmental Monitoring and Compliance Program (BECAMP). The DAF is located near the Mojave-Great Basin desert transition zone 27 km north of Mercury. The area immediately around the DAF building complex is a gentle slope cut by 1 to 3 m deep arroyos, and occupied by transitional vegetation. In 1994, construction activities were largely limited to work inside the perimeter fence. The DAF was still in a preoperational mode in 1994, and no nuclear materials were present. The DAF facilities were being occupied so there was water in the sewage settling pond, and the roads and lights were in use. Sampling activities in 1994 represent the first year in the proposed monitoring scheme. The proposed biological monitoring plan gives detailed experimental protocols. Plant, lizard, tortoise, small mammal, and bird surveys were performed in 1994. The authors briefly outline procedures employed in 1994. Studies performed on each taxon are reviewed separately then summarized in a concluding section.

    The Arroyo Seco 2 site contains a rich archaeological record, exceptional for South America, to explain the expansion of Homo sapiens into the Americas and their interaction with extinct Pleistocene mammals. The following paper provides a detailed overview of material remains found in the earliest cultural episodes at this multi-component site, dated between ca. 12,170 14C yrs B.P. (ca. 14,064 cal yrs B.P.) and 11,180 14C yrs B.P. (ca. 13,068 cal yrs B.P.). Evidence of early occupations includes the presence of lithic tools, a concentration of Pleistocene species remains, human-induced fractured animal bones, and a selection of skeletal parts of extinct fauna. The occurrence of hunter-gatherers in the Southern Cone at ca. 14,000 cal yrs B.P. is added to the growing list of American sites that indicate a human occupation earlier than the Clovis dispersal episode, but posterior to the onset of the deglaciation of the Last Glacial Maximum (LGM) in the North America.

  18. Future Temperatures and Precipitations in the Arid Northern-Central Chile: A Multi-Model Downscaling Approach

    Souvignet, M.; Heinrich, J.

    2010-03-01

    Downscaling of global climate outputs is necessary to transfer projections of potential climate change scenarios to local levels. This is of special interest to dry mountainous areas, which are particularly vulnerable to climate change due to risks of reduced freshwater availability. These areas play a key role for hydrology since they usually receive the highest local precipitation rates stored in form of snow and glaciers. In the central-northern Chile (Norte Chico, 26-33ºS), where agriculture still serves as a backbone of the economy as well as ensures the well being of people, the knowledge of water resources availability is essential. The region is characterised by a semiarid climate with a mean annual precipitation inferior to 100mm. Moreover, the local climate is also highly influenced by the ENSO phenomenon, which accounts for the strong inter-annual variability in precipitation patterns. Although historical and spatially extensive precipitation data in the headwaters of the basins in this region are not readily available, records at coastal stations show worrisome trends. For instance, the average precipitation in La Serena, the most important city located in the Coquimbo Region, has decreased dramatically in the past 100 years. The 30-year monthly average has decreased from 170 mm in the early 20th century to values less than 80 mm nowadays. Climate Change is expected to strengthen this pattern in the region, and therefore strongly influence local hydrological patterns. The objectives of this study are i) to develop climate change scenarios (2046-2099) for the Norte Chico using multi-model predictions in terms of temperatures and precipitations, and ii) to compare the efficiency of two downscaling techniques in arid mountainous regions. In addition, this study aims at iii) providing decision makers with sound analysis of potential impact of Climate Change on streamflow in the region. For the present study, future local climate scenarios were developed

    The high efficiency for detecting high-fold γ rays by large Ge arrays makes it possible to study the detailed spectroscopy of many neutron-rich nuclei produced by fission. Major progress has been made using sealed spontaneous fission sources. Considerable improvement in selectivity is provided, with an open source, both by gating on isomers and by detection of both fission fragments in coincidence with the deexcitation γ rays (see the preceding contribution). The reconstructed kinematics allows a measure of fragment mass and the Doppler shift correction of γ rays. In a recent experiment, fission fragments were detected using half of the CHICO array and an annular PPAC in coincidence with deexcitation γ rays detected by the Rochester array of eight Compton-suppressed Ge detectors. The annular PPAC was located only 1.0" from a 3.7 μCi ^252Cf source for efficient isomer tagging. The correlation was studied between delayed, within a time window between 150 ns and 10 μs after a fission occurring, and prompt γ rays. Several prominent feeding patterns to isomers in the mass region around 100 and 130 are identified by such correlation study. Experimental details and results will be presented.
