Anima: Modular Workflow System for Comprehensive Image Data Analysis
Rantanen, Ville; Valori, Miko; Hautaniemi, Sampsa
2014-01-01
Modern microscopes produce vast amounts of image data, and computational methods are needed to analyze and interpret these data. Furthermore, a single image analysis project may require tens or hundreds of analysis steps starting from data import and pre-processing to segmentation and statistical analysis; and ending with visualization and reporting. To manage such large-scale image data analysis projects, we present here a modular workflow system called Anima. Anima is designed for comprehensive and efficient image data analysis development, and it contains several features that are crucial in high-throughput image data analysis: programing language independence, batch processing, easily customized data processing, interoperability with other software via application programing interfaces, and advanced multivariate statistical analysis. The utility of Anima is shown with two case studies focusing on testing different algorithms developed in different imaging platforms and an automated prediction of alive/dead C. elegans worms by integrating several analysis environments. Anima is a fully open source and available with documentation at www.anduril.org/anima. PMID:25126541

[Figures of anima in the Odyssey].
Meneghello, Mauro
2012-01-01
Feminine characters in the Odyssey show different aspects of the archetype: Mother and Anima (C.G. Jung). From an Analytical Psychology perspective the encounters of Odysseus with goddesses: Circe, Calypso, Ino are looked at as different and successive stages of the hero's way into the inconscious, who shows himself in feminine figures, being masculine the consciousness of the hero. Nausicaa is a new, nearly-human figure of Anima who appears after the symbolic death of Odysseus and leads him to the royal couple Alcinous-Arete: in front of them all he finds his new, reborn, personality by creating and narrating his own myth.
Characteristics of Metals Concentrations in in the Animas and ...
The accidental release of 11.3 million liters (~ 3,000,000 gallons) of acidic mine water from the Gold King Mine (GKM) in southwestern Colorado on August 5, 2015, created high concentrations of dissolved and particulate metals into the Animas River over about a 12-hour period. The release traveled as a coherent plume through 550 km (342 miles) of the Animas and San Juan Rivers over an 8-day period before ultimately reaching Lake Powell, Utah. Extensive monitoring of water and sediments by EPA, States, Tribes and others was augmented by water quality modeling to characterize the release. Presented at the New Mexico Water Institute Symposium, 2nd Annual Conference on Environmental Conditions of the Animas and San Juan Watersheds with Emphasis on Gold King Mine and Other Mine Waste Issues.

A hazard assessment of selenium was conducted for the Animas La Plata Project, a multiple-use water development proposed for Colorado and New Mexico by the United States Bureau of Reclamation. A published protocol for aquatic hazard assessment of selenium was applied to environmental monitoring data to assess current threats to biota in the water supply rivers (Animas...

Acid drainage from abandoned mines and from naturally-acidic rocks and soil in the upper Animas River watershed of Colorado generates elevated concentrations of acidity and dissolved metals in stream waters and deposition of metal-contaminated particulates in streambed sediments, resulting in both toxicity and habitat degradation for stream biota. High concentrations of iron (Fe), aluminum (Al), zinc (Zn), copper (Cu), cadmium (Cd), and lead (Pb) occur in acid streams draining headwaters of the upper Animas River watershed, and high concentrations of some metals, especially Zn, persist in circumneutral reaches of the Animas River and Mineral Creek, downstream of mixing zones of acid tributaries. Seasonal variation of metal concentrations is reflected in variation in toxicity of stream water. Loadings of dissolved metals to the upper Animas River and tributaries are greatest during summer, during periods of high stream discharge from snowmelt and monsoonal rains, but adverse effects on stream biota may be greater during winter low-flow periods, when stream flows are dominated by inputs of groundwater and contain greatest concentrations of dissolved metals. Fine stream-bed sediments of the upper Animas River watershed also contain elevated concentrations of potentially toxic metals. Greatest sediment metal concentrations occur in the Animas River upstream from Silverton, where there are extensive deposits of mine and mill tailings, and in mixing zones in the Animas River and lower Mineral Creek, where precipitates of Fe and Al oxides also contain high concentrations of other metals. This report summarizes the findings of a series of toxicity studies in streams of the upper Animas River watershed, conducted on-site and in the laboratory between 1998 and 2000. The objectives of these studies were: (1) to determine the relative toxicity of stream water and fine stream-bed sediments to fish and invertebrates; (2) to determine the seasonal range of toxicity in stream

This product consists of Adobe Acrobat .PDF format documents for 10 surficial geologic strip maps along the Animas River watershed from its major headwater tributaries, south to Durango, Colorado. The Animas River originates in the San Juan Mountains north of the historic mining town of Silverton, Colorado. The surficial geologic maps identify surficial deposits, such as flood-plain and terrace gravels, alluvial fans, glacial till, talus, colluvium, landslides, and bogs. Sixteen primary units were mapped that included human-related deposits and structures, eight alluvial, four colluvial, one glacial, travertine deposits, and undifferentiated bedrock. Each of the surficial geologic strip maps has .PDF links to surficial geology photographs, which enable the user to take a virtual tour of these deposits. Geochemical data collected from mapped surficial deposits that pre- and postdate mining activity have aided in determining the geochemical baseline in the watershed. Several photographs with their corresponding geochemical baseline profiles are accessible through .PDF links from several of the maps. A single coverage for all surficial deposits mapped is included as an ArcInfo shape file as an Arc Export format .e00 file. A gradient map for major headwater tributary streams to the Animas River is also included. The gradient map has stream segments that are color-coded based on relative variations in slope and .PDF format links to each stream gradient profile. Stream gradients were derived from U.S. Geological Survey 10-m digital elevation model data. This project was accomplished in support of the U.S. Geological Survey's Abandoned Mine Lands Initiative in the San Juan Mountains, Colorado.

The Gold King Mine spill in August 2015 released 11 million liters of metal-rich mine waste to the Animas River watershed, an area that has been previously exposed to historical mining activity spanning more than a century. Although adsorption onto fluvial sediments was responsible for rapid immobilization of a significant fraction of the spill-associated metals, patterns of longer-term mobility are poorly constrained. Metals associated with river sediments collected downstream of the Gold King Mine in August 2015 exhibited distinct presence and abundance patterns linked to location and mineralogy. Simulating riverbed burial and development of anoxic conditions, sediment microcosm experiments amended with Animas River dissolved organic carbon revealed the release of specific metal pools coupled to microbial Fe- and SO 4 2- -reduction. Results suggest that future sedimentation and burial of riverbed materials may drive longer-term changes in patterns of metal remobilization linked to anaerobic microbial metabolism, potentially driving decreases in downstream water quality. Such patterns emphasize the need for long-term water monitoring efforts in metal-impacted watersheds.

This report presents hydrologic, water-quality, and biologic toxicity data collected during the annual spring thaw of 2002 in the upper Animas River watershed near Silverton, Colorado. The spring-thaw runoff is a concern because elevated concentrations of iron oxyhydroxides can contain sorbed trace metals that are potentially toxic to aquatic life. Water chemistry of streams draining the San Juan Mountains is affected by natural acid drainage and weathering of hydrothermal altered volcanic rocks and by more than a century of mining activities. The timing of the spring-thaw sampling effort was determined by reviewing historical climate and stream-flow hydrographs and current weather conditions. Twenty-one water-quality samples were collected between 11:00 AM March 27, 2002 and 6:00 PM March 30, 2002 to characterize water chemistry at the A-72 gage on the upper Animas River below Silverton. Analyses of unfiltered water at the A-72 gage showed a relation between turbidity and total-recoverable iron concentrations, and showed diurnal patterns. Copper and lead concentrations were related to iron concentrations, indicating that these elements are probably sorbed to colloidal iron material. Calcium, strontium, and sulfate concentrations showed overall decreasing trends due to dilution, but the loads of those constituents increased over the sampling period. Nine water-quality samples were collected near the confluence of Mineral Creek with the Animas River, the confluence of Cement Creek with the Animas River, and on the upper Animas River above the confluence with Cement Creek (three samples at each site). A total of six bulk water-toxicity samples were collected before, during, and after the spring thaw from the Animas River at the A-72 gage site. Toxicity tests conducted with the bulk water samples on amphipods did not show strong differences in toxicity among the three sampling periods; however, toxicity of river water to fathead minnows showed a decreasing trend

This publication comprises a Volume Contents of chapters (listed below) and a CD-ROM of data (contents shown in column at right). The Animas River watershed in southwest Colorado is one of many watersheds in the western United States where historical mining has left a legacy of acid mine drainage and elevated concentrations of potentially toxic trace elements in surface streams. U.S. Geological Survey scientists have completed a major assessment of the environmental effects of historical mining in the Animas River watershed focusing on the area upstream of Silverton, Colo.?the Mineral Creek, Cement Creek, and upper Animas River basins. The study demonstrated how the watershed approach can be used to assess and rank mining-affected sites for possible cleanup. The study was conducted in collaboration with State and Federal land-management agencies and regional stakeholders groups.

Cement Creek, an acidic tributary, discharges into the circum-neutral Animas River (pH>7) in Silverton, Colorado located in the high-elevation San Juan Mountains. Mixing of Animas River water with acidic metal rich Cement Creek water raises water pH and produces metal precipitates. This report presents selected anion, cation, chloride, and sulfate data along with hydrologic data highlighting the mixing of these streams during the low-flow period in late summer 1997.

The water quality, habitats, and biota of streams in the upper Animas River watershed of Colorado, USA, are affected by metal contamination associated with acid drainage. We determined metal concentrations in components of the food web of the Animas River and its tributaries - periphyton (aufwuchs), benthic invertebrates, and livers of brook trout (Salvelinus fontinalis) - and evaluated pathways of metal exposure and hazards of metal toxicity to stream biota. Concentrations of the toxic metals cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) in periphyton, benthic invertebrates, and trout livers from one or more sites in the upper Animas River were significantly greater than those from reference sites. Periphyton from sites downstream from mixing zones of acid and neutral waters had elevated concentrations of aluminum (Al) and iron (Fe) reflecting deposition of colloidal Fe and Al oxides, and reduced algal biomass. Metal concentrations in benthic invertebrates reflected differences in feeding habits and body size among taxa, with greatest concentrations of Zn, Cu, and Cd in the small mayfly Rhithrogena, which feeds on periphyton, and greatest concentrations of Pb in the small stonefly Zapada, a detritivore. Concentrations of Zn and Pb decreased across each trophic linkage, whereas concentrations of Cu and Cd were similar across several trophic levels, suggesting that Cu and Cd were more efficiently transferred via dietary exposure. Concentrations of Cu in invertebrates and trout livers were more closely associated with impacts on trout populations and invertebrate communities than were concentrations of Zn, Cd, or Pb. Copper concentrations in livers of brook trout from the upper Animas River were substantially greater than background concentrations and approached levels associated with reduced brook trout populations in field studies and with toxic effects on other salmonids in laboratory studies. These results indicate that bioaccumulation and transfer of

Exploration for and production of coalbed methane has increased substantially in the Rocky Mountain region of the United States since the 1990s. During 1999-2004, annual production of natural gas (coalbed methane) from the Raton Basin in Las Animas County, Colorado, increased from 28,129,515 to 80,224,130 thousand cubic feet, and the annual volume of ground water coproduced by coalbed methane wells increased from about 949 million gallons to about 2,879 million gallons. Better definition of the hydrostratigraphic framework of the Raton, Vermejo, and Trinidad aquifers in the Raton Basin of southern Colorado is needed to evaluate the long-term effects of coalbed methane development on the availability and sustainability of ground-water resources. In 2001, the U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board, began a study to evaluate the hydrogeology of the Raton Basin in Huerfano and Las Animas Counties, Colorado. Geostatistical methods were used to map the altitude of and depths to the bottoms and tops (structure) and the apparent thicknesses of the Trinidad Sandstone, the Vermejo Formation, and the Raton Formation in Las Animas County, based on completion reports and drillers' logs from about 1,400 coalbed methane wells in the Raton Basin. There was not enough subsurface control to map the structural surfaces and apparent thicknesses of the aquifers in Huerfano County. Geostatistical methods also were used to map the regional water table in the northern part of Las Animas County, based on reported depth to water from completion reports of water-supply wells. Although these maps were developed to better define the hydrostratigraphic framework, they also can be used to determine the contributing aquifer(s) of existing water wells and to estimate drilling depths of proposed water wells. These maps of the hydrostratigraphic framework could be improved with the addition of measured sections and mapping of geologic contacts at outcrops

We applied spectroscopy, microscopy, diffraction, and aqueous chemistry methods to investigate the persistence of metals in water and sediments from the Animas River 13 days after the Gold King Mine spill (August 5, 2015). The Upper Animas River watershed, located in San Juan Colorado, is heavily mineralized and impacted by acid mine drainage, with low pH water and elevated metal concentrations in sediments (108.4 ± 1.8 mg kg -1 Pb, 32.4 ± 0.5 mg kg -1 Cu, 729.6 ± 5.7 mg kg -1 Zn, and 51 314.6 ± 295.4 mg kg -1 Fe). Phosphate and nitrogen species were detected in water and sediment samples from Farmington, New Mexico, an intensive agricultural area downstream from the Animas River, while metal concentrations were low compared to those observed upstream. Solid-phase analyses of sediments suggest that Pb, Cu, and Zn are associated with metal-bearing jarosite and other minerals (e.g., clays, Fe-(oxy)hydroxides). The solubility of jarosite at near-neutral pH and biogeochemical processes occurring downstream could affect the stability of metal-bearing minerals in river sediments. This study contributes relevant information about the association of metal mixtures in a heavy mineralized semiarid region, providing a foundation to better understand long-term metal release in a public and agricultural water supply.

Determination of the pre-mining geochemical baseline in bed sediments and the paleoecology in a watershed impacted by historical mining activity is of utmost importance in establishing watershed restoration goals. We have approached this problem in the Animas River watershed using geomorphologic mapping methods to identify old pre-mining sediments. A systematic evaluation of possible sites resulted in collection of a large number of samples of pre-mining sediments, overbank sediments, and fluvial tailings deposits from more than 50 sites throughout the watershed. Chemical analysis of individual stratigraphic layers has resulted in a chemical stratigraphy that can be tied to the historical record through geochronological and dendochronological studies at these sites. Preliminary analysis of geochemical data from more than 500 samples from this study, when coupled with both the historical and geochronological record, clearly show that there has been a major impact by historical mining activities on the geochemical record preserved in these fluvial bed sediments. Historical mining activity has resulted in a substantial increase in metals in the very fine sand to clay sized component of the bed sediment of the upper Animas River, and Cement and Mineral Creeks. Enrichment factors for metals in modern bed sediments, relative to the pre-mining sediments, range from a factor of 2 to 6 for arsenic, 4 to more than 10 for cadmium, 2 to more than 10 for lead, 2 to 5 for silver, and 2 to more than 15 for zinc. However, the pre-mining bed sediment geochemical baseline is high relative to crustal abundance levels of many orerelated metals and the watershed would readily be identified as a highly mineralized area suitable for mineral exploration if it had not been disturbed by historical mining activity. We infer from these data that the water chemistry in the streams was less acidic prior to historical mining activity in the watershed. Paleoentologic evidence does not indicate a

Visible-wavelength and near-infrared image cubes of the Animas River watershed in southwestern Colorado have been acquired by the Jet Propulsion Laboratory's Airborne Visible and InfraRed Imaging Spectrometer (AVIRIS) instrument and processed using the U.S. Geological Survey Tetracorder v3.6a2 implementation. The Tetracorder expert system utilizes a spectral reference library containing more than 400 laboratory and field spectra of end-member minerals, mineral mixtures, vegetation, manmade materials, atmospheric gases, and additional substances to generate maps of mineralogy, vegetation, snow, and other material distributions. Major iron-bearing, clay, mica, carbonate, sulfate, and other minerals were identified, among which are several minerals associated with acid rock drainage, including pyrite, jarosite, alunite, and goethite. Distributions of minerals such as calcite and chlorite indicate a relationship between acid-neutralizing assemblages and stream geochemistry within the watershed. Images denoting material distributions throughout the watershed have been orthorectified against digital terrain models to produce georeferenced image files suitable for inclusion in Geographic Information System databases. Results of this study are of use to land managers, stakeholders, and researchers interested in understanding a number of characteristics of the Animas River watershed.

This circular covers the geology of the Pyramid Peak, Swallow Fork Peak, Table Top Mountain, and South Pyramid Peak 7-1/2-min quadrangles, which include the Lightning Dock KGRA. Hot wells (70 to 115.5/sup 0/C) seem to be structurally controlled by intersections of the ring-fracture zone of an Oligocene ash-flow tuff cauldron (Muir cauldron), a Miocene-to-Holocene north-trending basin-and-range fault (Animas Valley fault), and a northeast-trending lineament that appears to control anomalously heated underground waters and Pliocene-Pleistocene basalt cones in the San Bernardino, San Simon, and Animas Valleys. The Muir cauldron, approximately 20 km in diameter, collapsed in two stages, each associated withmore » the eruption of a rhyolite ash-flow-tuff sheet and of ring-fracture domes. Most of the hydrothermal alteration of the Lightning Dock KGRA is related to the first stage of eruption and collapse, not to the modern geothermal system. Contrary to previous reports, no silicic volcanic rocks younger than basin-and-range faulting are known; unconformities beneath rhyolite ring-fracture domes are caused by Oligocene caldera collapse, not by basin-and-range faulting. The Animas Valley is the site of widespread post-20 My travertine deposits and near-surface veins of calcite, fluorite, and/or psilomelane, controlled by north- or northwest-trending basin-and-range faults. The fluoride-bearing waters of the Lightning Dock KGRA may be a late stage of this hydrothermal activity. Distribution of Pliocene-Pleistocene basalt suggests that deep-seated basalt near the solids may be the ultimate heat source.« less

Drainage from abandoned and inactive mines and from naturally mineralized areas in the San Juan Mountains of southern Colorado contributes metals to the upper Animas River near Silverton, Colorado. Tracer-injection studies and associated synoptic sampling were performed along two reaches of the upper Animas River to develop detailed profiles of stream discharge and to locate and quantify sources of metal loading. One tracer-injection study was performed in September 1997 on the Animas River reach from Howardsville to Silverton, and a second study was performed in August 1998 on the stream reach from Eureka to Howardsville. Drainage in the upper Animas River study reaches contributed aluminum, calcium, copper, iron, magnesium, manganese, sulfate, and zinc to the surface-water system in 1997 and 1998. Colloidal aluminum, dissolved copper, and dissolved zinc were attenuated through a braided stream reach downstream from Eureka. Instream dissolved copper concentrations were lower than the State of Colorado acute and chronic toxicity standards downstream from the braided reach to Silverton. Dissolved iron load and concentrations increased downstream from Howardsville and Arrastra Gulch, and colloidal iron remained constant at low concentrations downstream from Howardsville. Instream sulfate concentrations were lower than the U.S. Environmental Protection Agency's secondary drinking-water standard of 250 milligrams per liter throughout the two study reaches. Elevated zinc concentrations are the primary concern for aquatic life in the upper Animas River. In the 1998 Eureka to Howardsville study, instream dissolved zinc load increased downstream from the Forest Queen mine, the Kittimack tailings, and Howardsville. In the 1997 Howardsville to Silverton study, there were four primary areas where zinc load increased. First, was the increase downstream from Howardsville and abandoned mining sites downstream from the Cunningham Gulch confluence, which also was measured during

During the Last Glacial Maximum (LGM), a 5000 km2 ice cap covered the San Juan Mountains of southwest Colorado. The largest valley glacier draining this ice cap occupied the Animas Valley and flowed 91 km to the south. To characterize the post-LGM demise of the Animas Valley glacier, we employ cosmogenic 10Be to date the LGM terrace outside the terminal moraines and a suite of seven glacially polished bedrock samples. The 10Be depth profile within the terrace sediments suggests abandonment at 19.4 ± 1.5 ka. As deglaciation began, the ponding of Glacial Lake Durango behind the terminal moraines shut off fluvial sediment supply and caused terrace abandonment. The age of the terrace therefore records the initiation of LGM retreat. Negligible 10Be inheritance in the terrace profile suggests that glacial erosion of the bedrock valley floor from which sediments were derived erased all cosmogenic inventory. Glacial polish exposure ages monotonically decrease up-valley from 17.1 to 12.3 ka, with the single exception of a sample collected from a quartzite rib, yielding an average retreat rate of 15.4 m/yr. This trend and the lack of inherited cosmogenic nuclides in the terrace sediments imply that polish ages accurately record the glacial retreat history. Retreat of the Animas lobe began at a time of regional drying recorded in sediments and shoreline elevations of large lakes. Deglaciation lasted for ˜7.2 k.y., and was complete by 12.3 ± 1.0 ka. The retreat history followed the pattern of increasing insolation and was perhaps fastest during a time of regional drying.

During 1996 to 2000, the Bureau of Land Management, National Park Service, Environmental Protection Agency, United States Department of Agriculture (USDA) Forest Service, and the U.S. Geological Survey (USGS) developed a coordinated strategy to (1) study the environmental effects of historical mining on Federal lands, and (2) remediate contaminated sites that have the greatest impact on water quality and ecosystem health. This dataset provides information that contributes to these overall objectives and is part of the USGS Abandoned Mine Lands Initiative. Data presented here represent ferricrete occurrences and selected iron bogs and springs in the upper Animas River watershed in San Juan County near Silverton, Colorado. Ferricretes (stratified iron and manganese oxyhydroxide-cemented sedimentary deposits) are one indicator of the geochemical baseline conditions as well as the effect that weathering of mineralized rocks had on water quality in the Animas River watershed prior to mining. Logs and wood fragments preserved in several ferricretes in the upper Animas River watershed, collected primarily along streams, yield radiocarbon ages of modern to 9,580 years B.P. (P.L. Verplanck, D.B. Yager, and S.E. Church, work in progress). The presence of ferricrete deposits along the current stream courses indicates that climate and physiography of the Animas River watershed have been relatively constant throughout the Holocene and that weathering processes have been ongoing for thousands of years prior to historical mining activities. Thus, by knowing where ferricrete is preserved in the watershed today, land-management agencies have an indication of (1) where metal precipitation from weathering of altered rocks has occurred in the past, and (2) where this process is ongoing and may confound remediation efforts. These data are included as two coverages-a ferricrete coverage and a bogs and springs coverage. The coverages are included in ArcInfo shapefile and Arc

Acidic waters from Cement Creek discharge into the circum-neutral Animas River in a high-elevation region of the San Juan Mountains near Silverton, Colorado. Cement Creek is acidic and enriched in metals and sulfate because it is fed by discharges from abandoned mines and natural mineral deposits. Mixing with the Animas River raises the pH and produces precipitates of iron and aluminum (oxy)hydroxides, which in turn can adsorb other metals. This confluence was studied in 1996 and 1997 to better understand mixing and sorption processes which are common during the neutralization of acidic streams. The photographs in this report show flow braiding and other features that influenced the way the two streams mixed during the late summers of the two years. They also show 'banding' due to incomplete mixing and 'opalescence' due to chemical reactions and the formation of colloidal-size particles in the mixing zone.
The accidental release of 11.3 million liters (~ 3,000,000 gallons) of acidic mine water from the Gold King Mine (GKM) in southwestern Colorado on August 5, 2015, created high concentrations of dissolved and particulate metals into the Animas River over about a 12-hour period. Th...

Mottainai: a Japanese sense of anima mundi.
Sato, Yuriko
2017-02-01
The Japanese expression 'Mottainai!' can be translated as 'What a waste!' or 'Don't be wasteful!' However, mottainai means much more than that. It expresses a sense of concern or regret for whatever is wasted because its intrinsic value is not properly utilized. Buddhism and Japan's indigenous religion, Shinto, are integral to the Japanese psyche, accordingly the other-than-human world is also experienced and lived in daily life. In the Japanese worldview everything in nature is endowed with spirit, every individual existence is dependent on others and all are connected in an ever-changing world. Mottainai offers a glimpse of the anima mundi inherent in this worldview. This contrasts with our anthropocentric Zeitgeist, which manifests outwardly as environmental crisis and inwardly as fixation upon social interactions, especially through communication technologies, to the exclusion of all else. Jung's statement, 'The decisive question for man is: Is he related to something infinite or not? That is the telling question of his life', has never been more pertinent. Encounters beyond the human world could be understood as touching this 'something infinite', and the apparent benefits of such experiences in the analytical process are illustrated with clinical vignettes from the author's practice. © 2017, The Society of Analytical Psychology.

As part of the Clean Water Act of 1972 (Public Law 92-500), all States are required to establish water-quality standards for every river basin in the State. During 1994, the Colorado Department of Public Health and Environment proposed to the Colorado Water Quality Control Commission (CWQCC) an aquatic-life standard of 225 µg/L (micrograms per liter) for the dissolved-zinc concentration in the Animas River downstream from Silverton (fig.1). The CWQCC delayed implementation of this water-quality standard until further information was collected and a plan for the cleanup of abandoned mines was developed. Dissolved-zinc concentrations in this section of the river ranged from about 270 µg/L during high flow, when rainfall and snowmelt runoff dilute the dissolved minerals in the river (U.S. Geological Survey, 1996, p. 431), to 960 µg/L (Colorado Department of Public Health and Environment, written commun., 1996) during low flow (such as late summer and middle winter when natural springs and drainage from mines are the main sources for the streams). Mining sites in the basin were developed between about 1872 and the 1940's, with only a few mines operated until the early 1990's. For local governments, mining sites represent part of the Nation's heritage, tourists are attracted to the historic mining sites, and governments are obligated to protect the historic mining sites according to the National Historic Preservation Act (Public Law 89-665). In the context of this fact sheet, the term "natural sources of dissolved minerals" refers to springs and streams where no effect from mining were determined. "Mining-related sources of dissolved minerals" are assumed to be: (1 ) Water draining from mines , and (2) water seeping from mine-waste dump pile where the waste piles were saturated by water draining from mines. Although rainfall and snowmelt runoff from mine-waste piles might affect water quality in streams, work described in this fact sheet was done during low

Following the release of three million gallons of metals laden surface water from the Gold King Mine in August 2015, surface-water samples were collected in the New Mexico reach of the Animas and San Juan Rivers during 2016 snowmelt and in the Animas River during three 2016 monsoonal storms. These samples were evaluated for dissolved (<0.45 µm) and total (unfiltered) concentrations of trace elements including aluminum, arsenic, iron, lead, and manganese. Dissolved concentrations of aluminum, iron, and lead account for between 0.70 % and 14% of their total metal concentrations; the manganese and arsenic range of dissolved concentrations compared to total concentrations ranges from 1.2%-75%. Concentrations of total aluminum, arsenic, iron, lead, manganese increase during the rising limb of all hydrographs, suggesting a relationship with sediment concentrations, which also increase with increasing streamflow. Aluminum and iron have the highest total concentrations, 63,400 µg/L and 82,500 µg/L, respectively. Lead and arsenic total concentrations range from 0.67 to 65.5 µg/L and 0.6 to 17 µg/L, respectively. Metals such as lead and arsenic are known to adsorb to iron and aluminum particulates. During snowmelt, the relations of total aluminum and iron to total lead and arsenic are positive and linear, while during monsoonal events, the relations are polynomial. These relations may be due to the source of metals during the specific hydrologic event. Relations between discrete water quality data and continuously monitored field parameters such as turbidity and specific conductance can provide insight to changes in concentrations of the river on a finer time scale. Regression models developed for selected sites on the Animas and San Juan Rivers show that flow, turbidity and specific conductance may be useful in understanding the relationship between total metal concentrations and real-time parameters. Surrogates for suspended sediment such as hydroacoustic may also be

Listening analytically is not listening just to what is said but listening to what is just below the surface waiting to be said. This paper looks at Jung's insight into a 'third thing' being created intra-psychically and within the analytic encounter. Ogden's concept of an 'analytic third' is used to describe the clinical aspects of this thirdness. This paper explores: how the state of thirdness is created and accessed through use of reverie and associative dreaming; how the material emerging from it is used in a from or about manner; and the eventual fate of the third in a successful analysis by a reexamination of plates four and ten of the Rosarium. The focus is particularly on the awareness and possible meanings of mythological motifs appearing in the mind of the analyst while in session. Thirdness can be viewed as the interpersonal aspect of the anima media natura and functions in a way that informs us of permeability in and between individuals, while the operation of the anima mundi means that there is always an inseparability of the individual with the world. © 2017, The Society of Analytical Psychology.

/ This paper explores the new politics of western water policy through an examination of the Animas-La Plata water project and implementation of the Endangered Species Act. It is suggested that the focus of western water programming has shifted from the source of distributed funds, the United States Congress, to the agencies originally created to deliver federal benefits because funding for new project construction has not been forthcoming. Under this new system, members of Congress continue to excite their constituents with promises of money for new project starts, while the administrative agencies perform the myriad duties needed to keep these projects alive. The result is that political objectives have replaced operational/management objectives in administrative processes. In this case, the author demonstrates how resource managers in the Bureau of Reclamation manipulated hydrological analysis to control administrative process, why their manipulation was unfair, and perhaps illegal, and why biologists from the US Fish and Wildlife Service accepted the analysis. While ostensibly protecting all interests, the result is that none of the objectives of federal water programming are achieved.

Some considerations concerning the alchemy of the De anima in arte alchemiae of pseudo-Avicenna.
Moureau, Sébastien
2009-03-01
This article explains some essential features of the alchemical doctrine of the De anima in arte alchemiae, a treatise written in Spain during the twelfth century (in Arabic, but only the Latin translation remains), and wrongly attributed to Avicenna. It shows that pseudo-Avicenna uses alchemical principles and elixir theory directly inspired by Jabirian texts, and classification of materials influenced by al-Razi. The alchemy of pseudo-Avicenna is entirely based on operations on the four elements: the alchemist has to reduce hair, blood or eggs to their elements, and isolate one of their essential properties (warmth, coldness, moisture and dryness), so that he can change the proportion of essential properties of the body he wants to transmute into gold or silver. The preparation made from hair, blood or eggs (the isolated property) is what he calls the elixir.

Historical production of metals in the western United States has left a legacy of acidic drainage and toxic metals in many mountain watersheds that are a potential threat to human and ecosystem health. Studies of the effects of historical mining on surface water chemistry and riparian habitat in the Animas River watershed have shown that cost-effective remediation of mine sites must be carefully planned. Of the more than 5400 mine, mill, and prospect sites in the watershed, 80 sites account for more than 90% of the metal loads to the surface drainages. Much of the low pH water and some of the metal loads are the result of weathering of hydrothermally altered rock that has not been disturbed by historical mining. Some stream reaches in areas underlain by hydrothermally altered rock contained no aquatic life prior to mining. Scientific studies of the processes and metal-release pathways are necessary to develop effective remediation strategies, particularly in watersheds where there is little land available to build mine-waste repositories. Characterization of mine waste, development of runoff profiles, and evaluation of ground-water pathways all require rigorous study and are expensive upfront costs that land managers find difficult to justify. Tracer studies of water quality provide a detailed spatial analysis of processes affecting surface- and ground-water chemistry. Reactive transport models were used in conjunction with the best state-of-the-art engineering solutions to make informed and cost-effective remediation decisions. Remediation of 23% of the high-priority sites identified in the watershed has resulted in steady improvement in water quality. More than $12 million, most contributed by private entities, has been spent on remediation in the Animas River watershed. The recovery curve for aquatic life in the Animas River system will require further documentation and long-term monitoring to evaluate the effectiveness of remediation projects implemented.

Existe estigma relacionado al VIH. A las personas con VIH/SIDA-PCVS se les viola sus derechos y obstaculiza su bienestar mental/físico. Profesionales de la salud-PS son fuente de apoyo primordial, sin embargo estos/as le estigmatizan. Es útil adiestrar a PS en relación al estigma social. Implantamos la intervención para reducir el estigma relacionado al VIH/SIDA con 507 estudiantes de medicina. Resultó ser una intervención efectiva, hubo reducción en los niveles de estigma a partir de nuestra intervención y diferencias significativas con el grupo control (p≤.05). Generar espacios de adiestramiento para atender el estigma relacionado al VIH/SIDA es pertinente para la psicología comunitaria porque colaboramos en la reducción de actitudes estigmatizantes que afectan adversamente la prevención de nuevas infecciones, la adherencia al tratamiento antirretroviral y la calidad de vida.

One of the important types of information needed to characterize water quality in streams affected by historical mining is the seasonal pattern of toxic trace-metal concentrations and loads. Seasonal patterns in water quality are estimated in this report using a technique called water-quality profiling. Water-quality profiling allows land managers and scientists to assess priority areas to be targeted for characterization and(or) remediation by quantifying the timing and magnitude of contaminant occurrence. Streamflow and water-quality data collected at 15 sites in the upper Animas River Basin during water years 1991?99 were used to develop water-quality profiles. Data collected at each sampling site were used to develop ordinary least-squares regression models for streamflow and constituent concentrations. Streamflow was estimated by correlating instantaneous streamflow measured at ungaged sites with continuous streamflow records from streamflow-gaging stations in the subbasin. Water-quality regression models were developed to estimate hardness and dissolved cadmium, copper, and zinc concentrations based on streamflow and seasonal terms. Results from the regression models were used to calculate water-quality profiles for streamflow, constituent concentrations, and loads. Quantification of cadmium, copper, and zinc loads in a stream segment in Mineral Creek (sites M27 to M34) was presented as an example application of water-quality profiling. The application used a method of mass accounting to quantify the portion of metal loading in the segment derived from uncharacterized sources during different seasonal periods. During May, uncharacterized sources contributed nearly 95 percent of the cadmium load, 0 percent of the copper load (or uncharacterized sources also are attenuated), and about 85 percent of the zinc load at M34. During September, uncharacterized sources contributed about 86 percent of the cadmium load, 0 percent of the copper load (or uncharacterized

Federal land managers along with local stakeholders in the Upper Animas River watershed near Silverton, Colorado are actively designing and implementing mine waste remediation projects to mitigate the effects of acid mine drainage from several abandoned hard rock metal mines and mills. Local source rocks with high acid neutralization capacity (ANC) within the watershed are of interest to land managers for use in these remediation projects. A suite of representative samples was collected from propylitic to weakly sericitic-altered volcanic and plutonic rocks exposed in outcrops throughout the watershed. Acid-base accounting laboratory methods coupled with mineralogic and geochemical characterization provide insight into lithologies that have a range of ANC and net acid production (NAP). Petrophysical lab determinations of magnetic susceptibility converted to estimates for percent magnetite show correlation with the environmental properties of ANC and NAP for many of the lithologies. A goal of our study is to interpret watershed-scale airborne magnetic data for regional mapping of rocks that have varying degrees of ANC and NAP. Results of our preliminary work are presented here.

This map was produced to provide hard-copy and digital data for alteration assemblages in the historical mining area centered on the Tertiary San Juan and Silverton calderas. The data have direct application to geoenvironmental and mineral exploration objectives. This dataset represents alteration mapping for the upper Animas River watershed near Silverton, Colorado. The map is based on detailed 1:12,000-scale field mapping, X-ray diffraction (XRD) analysis, mineral mapping by remote sensing (AVIRIS) data, and 1:24,000-scale aerial photographic interpretation. Geologic structures were compiled and generalized from multiple published and unpublished sources (Burbank and Luedke, 1964; Steven and others, 1974; Luedke and Burbank 1975a, b; Lipman, 1976; Luedke and Burbank, 1987; Luedke, 1996) (see Index Map). Unpublished mapping of the Ironton quadrangle by D.J. Bove and J.P. Kurtz in 1997-1999 was included.

Two Gram-stain-variable, non-motile, catalase-positive and cytochrome c oxidase-negative bacteria, designated AK20-18 T and AM20-54, were isolated from forest soil samples collected in the Italian Alps. Growth occurred at a temperature range of 5-30 °C, at pH 6-9 and in the presence of 0-5 % (w/v) NaCl. The 16S rRNA gene sequence similarity between strains AK20-18 T and AM20-54 was 100 %. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain AK20-18 T had highest 16S rRNA gene sequence similarity with the type strain of Arthrobacter psychrochitiniphilus (96.9 %). The cell-wall peptidoglycan structure of strain AK20-18 T was of the type A3alpha l-Lys-l-Thr-l-Ala2 (A11.27). The whole-cell sugars were galactose, ribose and lesser amounts of mannose. The major respiratory quinone of the two strains was menaquinone 9(H2) [MK-9(H2)], whereas MK-10(H2) was a minor component. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and unknown glycolipids. The major cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. The genomic DNA G+C content was 59.9 mol%. Combined data of phylogenetic, phenotypic and chemotaxonomic analyses demonstrated that strains AK20-18 T and AM20-54 represent a novel genus and species, for which the name Psychromicrobium silvestre gen. nov., sp. nov. is proposed. The type strain of Psychromicrobium silvestregen. nov., sp. nov. is AK20-18 T (=DSM 102047 T =LMG 29369 T ).

Field observations, sampling of mine dumps and mine drainage waters, and laboratory studies of dump materials have been made at mining areas deemed to be on public lands administered by the U. S. Bureau of Land Management (BLM) in the Upper Animas River watershed. Results of chemical analyses of dump materials, leachates of those materials, and surface waters draining mines or dumps provide indications of where acid is generated or consumed, and metal concentrations below mines or dumps. Information on sites previously identified as needing reclamation is reviewed and available geochemical information is used to rank 26 sites into four classes of priority for reclamation. Although there are more than a thousand mining sites (productive mines and prospects) on BLM lands in the Upper Animas River watershed study area, the majority are very small (less than about 70 cubic yards of dump material), are more than 2 miles from a major stream, or so inaccessible as to prohibit reclamation. In the summers of 1997 and 1998 approximately 200 sites were observed and more than 100 of these that appeared to have the potential to geochemically impact the watershed were examined more carefully and sampled. Building upon the prior work of the BLM and associated agencies, this work attempted to identify the most significant sources of mine-related contamination and to rank those sites as to priority for reclamation. These most significant mining areas have been examined within a geologic framework and were evaluated by multiple criteria, including tendency to generate acid and release toxic metals, observed damage to vegetation, potential to release metals based on leach tests, and likelihood of transport into streams of the watershed. No single measurable parameter, such as metal concentration, can be used to rank the sites. Rather, subjective estimates are required to evaluate combinations or interactions among several parameters. The most subjective estimate, while ranking

Dinosaur fossils are present in the Paleocene Ojo Alamo Sandstone and Animas Formation in the San Juan Basin, New Mexico, and Colorado. Evidence for the Paleo-cene age of the Ojo Alamo Sandstone includes palynologic and paleomagnetic data. Palynologic data indicate that the entire Ojo Alamo Sandstone, including the lower dinosaur-bearing part, is Paleocene in age. All of the palynomorph-productive rock samples collected from the Ojo Alamo Sandstone at multiple localities lacked Creta-ceous index palynomorphs (except for rare, reworked specimens) and produced Paleocene index palynomorphs. Paleocene palynomorphs have been identified strati-graphically below dinosaur fossils at two separate localities in the Ojo Alamo Sand-stone in the central and southern parts of the basin. The Animas Formation in the Colorado part of the basin also contains dinosaur fossils, and its Paleocene age has been established based on fossil leaves and palynology. Magnetostratigraphy provides independent evidence for the Paleocene age of the Ojo Alamo Sandstone and its dinosaur-bearing beds. Normal-polarity magnetochron C29n (early Paleocene) has been identified in the Ojo Alamo Sandstone at six localities in the southern part of the San Juan Basin. An assemblage of 34 skeletal elements from a single hadrosaur, found in the Ojo Alamo Sandstone in the southern San Juan Basin, provided conclusive evidence that this assemblage could not have been reworked from underlying Cretaceous strata. In addition, geochemical studies of 15 vertebrate bones from the Paleocene Ojo Alamo Sandstone and 15 bone samples from the underlying Kirtland Formation of Late Creta-ceous (Campanian) age show that each sample suite contained distinctly different abundances of uranium and rare-earth elements, indicating that the bones were miner-alized in place soon after burial, and that none of the Paleocene dinosaur bones ana-lyzed had been reworked. ??

El estigma relacionado con el VIH/SIDA continúa siendo un obstáculo para la prevención primaria y secundaria del VIH. Las consecuencias para las personas que viven con la enfermedad han sido muy documentadas y continúan siendo una gran preocupación para las personas que proveen servicios de salud y para aquellas que investigan el tema. Estas consecuencias son preocupantes cuando el estigma emana de profesionales de la salud porque se puede limitar el acceso a los servicios. Uno de los principales obstáculos para la investigación del estigma relacionado con el VIH en Puerto Rico es la falta de instrumentos cuantitativos para evaluar las manifestaciones del estigma entre profesionales de la salud. El objetivo principal de este estudio fue desarrollar y probar las propiedades psicométricas de una escala sobre el estigma relacionado con el VIH/SIDA culturalmente apropiada para personas que proveen servicios de salud puertorriqueñas y desarrollar una versión corta de la escala que pudiera usarse en escenarios clínicos con tiempo limitado. El instrumento desarrollado estuvo basado en evidencia cualitativa recopilada entre profesionales y estudiantes de profesiones de la salud puertorriqueños/as (n=80) y administrado a una muestra de 421 profesionales de la salud en adiestramiento. La escala contenía 12 dimensiones del estigma relacionado con el VIH/SIDA. El análisis cuantitativo corroboró 11 de ellas, teniendo como resultado un instrumento con validez y confiabilidad satisfactoria. Estas dimensiones, a su vez, fueron subcomponentes de un factor de estigma general superior. PMID:20333258

Historical and geologic records may be used to enhance magnitude estimates for extreme floods along mountain channels, as demonstrated in this study from the San Juan Mountains of Colorado. Historical photographs and local newspaper accounts from the October 1911 flood indicate the likely extent of flooding and damage. A checklist designed to organize and numerically score evidence of flooding was used in 15 field reconnaissance surveys in the upper Animas River valley of southwestern Colorado. Step-backwater flow modeling estimated the discharges necessary to create longitudinal flood bars observed at 6 additional field sites. According to these analyses, maximum unit discharge peaks at approximately 1.3 m3 s-1 km-2 around 2200 m elevation, with decreased unit discharges at both higher and lower elevations. These results (1) are consistent with Jarrett's (1987, 1990, 1993) maximum 2300-m elevation limit for flash-flooding in the Colorado Rocky Mountains, and (2) suggest that current Probable Maximum Flood (PMF) estimates based on a 24-h rainfall of 30 cm at elevations above 2700 m are unrealistically large. The methodology used for this study should be readily applicable to other mountain regions where systematic streamflow records are of short duration or nonexistent.

This article argues that an original debate over the relationship between time and the intellect took place in Northern Italy in the second half of the sixteenth century, which was part of a broader reflection on the temporality of human mental acts. While human intellectual activity was said to be 'above time' during the Middle Ages, Renaissance scholars such as Marcantonio Genua (1491-1563), Giulio Castellani (1528-1586), Antonio Montecatini (1537-1599) and Francesco Piccolomini (1520-1604), greatly influenced by the Simplician and Alexandrist interpretations of Aristotle's works, proposed alterna- tive conceptions based on the interpretation of De anima 3.6 (430b 7-20) according to which intellectual acts happen in a both 'undivided' and 'divisible time'. In order to explain Aristotle's puzzling claim, they were led to conceive of intellectual activity as a process similar to sensation, corresponding to a certain lapse of time (Castellani), an instant (Montecatini), or a mix of instantaneousness and concrete duration (Piccolomini), depending on their theoretical options.

The aim of the present work conducted at the Refugio de Vida Silvestre Bahía Samborombón is to analyse the most relevant aspects of the fecundity of Chasmagnathus granulatus and Uca uruguayensis. Samplings were carried out from March 2001 to February 2003. Ovigerous females of U. uruguayensis (N = 13) and C. granulatus (N = 25) were found during spring and summer, their sizes (CW) varied from 9.1 to 11.7 microm for the former species and from 22.8 to 32.4 mm for the latter. The egg diameter in U. uruguayensis ranged from 245 to 260 microm for embryos in the early stage of development and from 250 to 345 microm for those in mid-developmental stage, while in C. granulatus from 250 to 345 microm and from 260 to 365 microm respectively. Fecundity varied from 1126 to 6745 eggs/brood in U. uruguayensis and 15688-57418 eggs/brood in C. granulatus. For those females with broods in mid-developmental stage, several relationships were made. For U. uruguayensis the best correlation coefficients were obtained for the relationships: female weight vs. egg mass weight and carapace width vs. egg mass weight; for C. granulatus the best association was obtained between female size and the egg number and the egg mass weight.

In July 1990, the U.S. Geological Survey began a study of the occurrence of natural gas in near-surface ground water in the Animas River valley in the San Juan Basin between Durango, Colorado, and Aztec, New Mexico. The general purpose of the study was to identify the sources and migration pathways of natural gas in nearsurface ground water in the study area. The purpose of this report is to present interpretive conclusions for the study, primarily based on data collected by the U.S. Geological Survey from August 1990 to May 1991.Seventy of the 205 (34 percent) groundwater samples collected during August-November 1990 had methane concentrations that exceeded the reporting limit of 0.005 milligram per liter. The maximum concentration was 39 milligrams per liter, and the mean concentration was 1.3 milligrams per liter. Samples from wells completed in bedrock have greater mean concentrations of methane than samples from wells completed in alluvium. Correlations indicate weak or nonexistent associations between dissolved-methane concentrations and concentrations of dissolved solids, major ions, bromide, silica, iron, manganese, and carbon dioxide. Dissolved methane was associated with hydrogen sulfide.Soil-gas-methane concentrations were measurable at few of 192 ground-water sites, even at sites at which ground water contained large concentrations of dissolved methane, which indicates that soil-gas surveys are not useful to delineate areas of gas-affected ground water. The reporting limit of 0.005 milligram per liter of gas was equaled or exceeded by 40 percent of soil-gas measurements adjacent to 352 gas-well casings. Concentrations of at least 100 milligrams per liter of gas were measured at 25 (7 percent) of the sites.Potential sources of gases in water, soil, gas-well surface casings, and cathodic-protection wells were determined on the basis of their isotopic and molecular compositions and available information about gas-well construction or leaks.

Early-modern Jesuit universities did not offer studies in medicine, and from 1586 onwards, the Jesuit Ratio studiorum prohibited digressions on medical topics in the Aristotelian curriculum. However, some sixteenth-century Jesuit text books used in philosophy classes provided detailed accounts on physiological issues such as sense perception and its organic location as discussed in Aristotle's De anima II, 7-11. This seeming contradiction needs to be explained. In this paper, I focus on the interst in medical topics manifested in a commentary by the Jesuits of Coimbra. Admittedly, the Coimbra commentary constituted an exception, as the Jesuit college that produced it was integrated in a royal university which had a strong interest in educating physicians. It will be claimed that the exclusion of medicine at Jesuit universities and colleges had its origin in rather incidental events in the course of the foundation of the first Jesuit university in Sicily. There, the lay professors of law and medicine intended to avoid subordination to the Jesuits and thereby provoked a conflict which finally led the Jesuit administration to refrain from including faculties of medicine and law in Jesuit universities. Towards the end of the sixteenth century, a veritable Jesuit animosity towards medicine emerged for philosophical and pedagogical reasons. This development reflects educational concerns within the Society as well as the role of commentaries on Aristotle for early-modern learning.

Resumo Contexto As amputações dos membros inferiores, sejam definidas como maiores ou menores, são um grave problema de saúde, com altos índices de morbimortalidade e de relevante impacto social. Diferentes características clínicas dos pacientes parecem estar relacionadas aos diferentes tipos de amputação realizados. Objetivos Analisar os fatores de risco presentes em pacientes submetidos a amputações de membros inferiores em hospital terciário. Métodos Estudo retrospectivo, transversal, envolvendo 109 pacientes submetidos a amputação de membro inferior em um período de 31 meses, através da análise de gênero e idade, 15 dados clínicos e cinco parâmetros laboratoriais presentes no momento da admissão. Os dados foram submetidos a estatística descritiva e comparativa através do teste t de Student não pareado (para variáveis numéricas), e dos testes de Mann-Whitney e exato de Fisher (para variáveis categóricas). Resultados Das 109 amputações realizadas, 59 foram maiores e 50 menores. A maioria dos pacientes era do gênero masculino (65%), e a média de idade foi de 65 anos (mín. 39, máx. 93). Dentre os fatores de risco observados, idade avançada, acidente vascular encefálico, isquemia, sepse e níveis baixos de hemoglobina e hematócrito estavam estatisticamente mais relacionados às amputações maiores (p < 0,05).

Habitat destruction may cause wildlife population fragmentation and is considered an important factor in small population species extinction. As wildlife populations become smaller, threats to their stability and persistence arise as a result of demographic, environmental and genetic stochastic factors. The aim of this work was to study the effects of population fragmentation on the long term viability of Alouatta palliata and Cebus capucinus populations, at Refugio de Vida Silvestre Privado Nogal, Sarapiquí (RVSPN), Heredia. For this we used the computer software VORTEX to run a population viability analysis (PVA) for both species. The input data of the PVA were taken from the demography structure of the RVSPN, literature sources from the species and from PVA related papers. We evaluated two sets of scenarios: small fragmented populations to reflect the population current state, and one larger and continuous population, to reflect the effect of reforestation actions followed by RVSPN to connect forest fragments. Results suggest that both A. palliata and C. capucinus can survive in isolated forest fragments. However, if different factors as inbreeding depression, catastrophes or habitat loss were incorporated to the scenarios, the small fragmented populations become unstable and the risk of extinction increased for both species. Continuous and larger populations were more robust against the threats incorporated in the scenarios when compared to the current situation of smaller and fragmented populations. The best management option for both species would be to continue reforestation efforts in the area to connect forest fragments, with the result of larger and continuous populations of both species. It is important to continue the observation of both species populations, and to promote a habitat management to reduce the negative effects of stochastic environmental events.

Eleven acid-sulphate and quartz-sericite-pyrite altered mine waste samples from the Animas River watershed in SW Colorado were subjected to a series of 5 to 6 successive leaches using the US EPA 1312 leach protocol to evaluate the transport of metals and loss of acidity from mine wastes as a function of time. Multi-acid digestion ICP-AES analyses, X-ray diffraction (XRD) mineral identification, total sulphur, and net acid potential (NAP) determinations were performed on the initial starting materials. Multiple leaching steps generally showed a 'flushing' effect, whereby elements loosely bound, presumably as water-soluble salts, were removed. Aluminum, Cd, Fe, Mg, Mn, Sr, Zn, and S showed decreasing concentration trends, whereas Cu concentrations showed initially decreasing trends, followed by increasing trends in later steps. Concentrations of Zn in the first leach step were independent of whole-sample Zn content. Lead and Ba concentrations consistently increased with each step, indicating that anglesite (PbSO4) and barite (BaSO4), respectively, were dissolving in successive leach steps. Comparison of Fe content with NAP resulted in a modest correlation. However, using the S analyses and XRD identification of sulphide minerals to apportion S amongst enargite, barite, anglesite/galena, and sphalerite, and assigning the remaining S to pyrite, provided a useful correlation between estimated pyrite content and NAP. Whole-sample mass loss correlated well with NAP, but individual elements' behaviors varied between positive correlation (e.g. Al, Fe, Mg), no apparent correlation (Ca, Cd, Pb, Zn), and negative correlation (Cu). Comparison of the summed titrated acidities of the leachates with the whole-sample NAP values yielded an estimate of the fraction of NAP consumed, and led to an estimate of the time it would take to consume the sample acidity by weathering. We estimate, on the basis of these experiments, the acidity in the upper 30 cm would be consumed in 200–1000

An overview of the Gold King Mine Release and its Transport ...
On August 5, 2015, a large acidic mine pool trapped behind a collapsed mine structure and rock debris in the Gold King Mine (GKM) was accidently breached releasing approximately 11.3 million liters (3 million gallons) of low pH (~3) metal contaminated mine drainage into a small tributary in the headwaters of the Animas River in southwestern Colorado. The release introduced approximately 490,000 kg of dissolved and particulate metals over a 12-hour period into the Animas River at Silverton, CO, located 13 km downstream from the mine. The mine effluent contained 2,900 kg of dissolved metals. Most of the released metals were eroded from the old waste pile outside the mine entrance and within Cement Creek by the rushing water. The release introduced large quantities of particulate aluminum, iron, manganese, lead, copper, arsenic and zinc to the Animas River, of which 15,000 kg was in dissolved form To be presented at the New Mexico Water Institute Symposium, 2nd Annual Conference on Environmental Conditionsof the Animas and San Juan Watersheds with Emphasis on Gold King Mine and Other Mine Waste Issues.

The U.S. Departments of Agriculture and Interior Abandoned Mine Lands (AML) Initiative is focused on the evaluation of the effect of past mining practices on the water quality and the riparian and aquatic habitats of impacted stream reaches downstream from historical mining districts located primarily on Federal lands. This problem is manifest in the eleven western states (west of longitude 102 degrees) where the majority of hardrock mines that had past production are located on Federal lands. In areas of temperate climate and moderate to heavy precipitation, the effects of rapid chemical and physical weathering of sulfides exposed on mine-waste dumps and acidic drainage from mines have resulted in elevated metal concentrations in the stream water and stream-bed sediment. The result of these mineral weathering processes has an unquantified impact on the quality of the water and the aquatic and riparian habitats that may limit their recreational resource value. One of the confounding factors in these studies is the determination of the component of metals derived from hydrothermally altered but unmined portions of these drainage basins. Several watersheds have been studied to evaluate the effects of acid mine drainage and acid rock drainage on the near-surface environment. The Animas River watershed in southwestern Colorado contains a large number of past-producing metal mines that have affected the watershed. Beginning in October 1996, the U.S. Geological Survey (USGS) began a collaborative study of these effects under the USGS-AML Initiative. In this report, we present the radionuclide and geochemical analytical results of sediment coring during 1997-1999 from two cores from oxbow lakes 0.5 mi. upstream from the 32nd Street Bridge near Durango, Colo., and from three cores from beaver ponds within the Mineral Creek drainage basin near Silverton, Colo.

Tracer-injection studies were done in Belcher Gulch in the upper Animas River watershed, southwestern Colorado, to determine whether the alpine stream infiltrates into underground mine workings of the North Star Mine and other nearby mines in the area. The tracer-injection studies were designed to determine if and where along Belcher Gulch the stream infiltrates into the mine. Four separate tracer-injec-tion tests were done using lithium bromide (LiBr), optical brightener dye, and sodium chloride (NaCl) as tracer solu-tions. Two of the tracers (LiBr and dye) were injected con-tinuously for 24 hours, one of the NaCl tracers was injected continuously for 12 hours, and one of the NaCl tracers was injected over a period of 1 hour. Concentration increases of tracer constituents were detected in water discharging from the North Star Mine, substantiating a surface-water and ground-water connection between Belcher Gulch and the North Star Mine. Different timing and magnitude of tracer breakthroughs indicated multiple flow paths with different residence times from the stream to the mine. The Pittsburgh and Sultan Mines were thought to physically connect to the North Star Mine, but tracer breakthroughs were inconclusive in water from these mines. From the tracer-injection tests and synoptic measure-ments of streamflow discharge, a conceptual model was devel-oped for surface-water and ground-water interactions between Belcher Gulch and the North Star Mine. This information, combined with previous surface geophysical surveys indicat-ing the presence of subsurface voids, may assist with decision-making process for preventing infiltration and for the remedia-tion of mine drainage from these mines.

Insulin pump systems now provide automated bolus calculators (ABCs) that electronically calculate insulin boluses to address carbohydrate intake and out-of-range blood glucose (bG) levels. We compared the efficacy of three ABCs (Accu-Chek(®) Combo [Roche Insulin Delivery Systems (IDS), Inc., Fishers, IN, a member of the Roche Group], Animas(®) 2020 [Animas Corp., West Chester, PA, a Johnson and Johnson company], and MiniMed Paradigm Bolus Wizard(®) [Medtronic MiniMed, Northridge, CA]) to safely reduce postprandial hyperglycemia in type 1 diabetes mellitus (T1DM). T1DM subjects (n = 24) were recruited at a single center for a prospective, triple crossover study. ABCs with the programmed target range (80-140 mg/dL) were used in random order. Postprandial hyperglycemia was induced by reducing the calculated bolus by 25%. Two hours after test meals, the ABCs were allowed to determine whether a correction bolus was needed. Differences between 6-h bG values after test meals that achieved 2-h postprandial hyperglycemia and the mean of the target range (110 mg/dL) were determined. The mean difference between 6-h bG levels following test meals and the 110 mg/dL bG target with the MiniMed device (47.4 ± 31.8 mg/dL) was significantly higher than the Animas (17.3 ± 30.9 mg/dL) and Roche IDS (18.8 ± 33.8 mg/dL) devices (P = 0.0022 and P = 0.0049, respectively). The number of meals with 2-h postprandial hyperglycemia and bG levels at 2 h was similar. Roche IDS and Animas devices recommended correction boluses significantly (P = 0.0001 and P = 0.0002, respectively) more frequently than the MiniMed device. ABC use was not associated with severe hypoglycemia. There was no significant difference in the rate of mild hypoglycemia (bG <60 mg/dL not requiring assistance) among the three groups (Roche IDS and Animas, n = 2; MiniMed, n = 0). In this study, the Roche IDS and Animas devices were more efficacious in controlling

rapidamente por varias razones, incluyendo perdidas debidas a diferentes tipos de depredadores. Estudios anteriores conducidos en el campo, y en jaulas de campo, han confirmado que las cepas de machos de laboratorio tienen menos capacidad de evadir depredadores que los machos silvestres. Estos estudios involucran, sin embargo, una considerable cantidad de manipulacion y observacion de depredadores, por lo que no son adecuados para ser usados como medidas rutinarias en los programas de cria masiva. Aqui describimos un metodo sencillo de control de calidad usando aspiradores para medir agilidad en la mosca del Mediterraneo y mostramos que este parametro esta relacionado a la capacidad de la moscas a evadir a depredadores. Aunque aun es necesario refinar la estandarizacion de este metodo para permitir la comparacion entre cepas, los resultados confirman la importancia de tener un metodo rutinario para medir la capacidad de evasion de depredadores en cepas de cria de laboratorio de la mosca del Mediterraneo. Ademas de medir este parametro de control de calidad de los machos esteriles, el metodo descrito podria tambien ser usado para la seleccion sistematica de cepas con una mayor capacidad de evasion de depredadores.

Stream discharges and concentrations of dissolved and colloidal metals (Al, Ca, Cu, Fe, Mg, Mn, Pb, and Zn), SO4, and dissolved silica were measured to identify chemical transformations and determine mass transports through two mixing zones in the Animas River that receive the inflows from Cement and Mineral Creeks. The creeks were the dominant sources of Al, Cu, Fe, and Pb, whereas the upstream Animas River supplied about half of the Zn. With the exception of Fe, which was present in dissolved and colloidal forms, the metals were dissolved in the acidic, high-SO4 waters of Cement Creek (pH 3.8). Mixing of Cement Creek with the Animas River increased pH to near-neutral values and transformed Al and some additional Fe into colloids which also contained Cu and Pb. Aluminium and Fe colloids had already formed in the mildly acidic conditions in Mineral Creek (pH 6.6) upstream of the confluence with the Animas River. Colloidal Fe continued to form downstream of both mixing zones. The Fe- and Al-rich colloids were important for transport of Cu, Pb, and Zn, which appeared to have sorbed to them. Partitioning of Zn between dissolved and colloidal phases was dependent on pH and colloid concentration. Mass balances showed conservative transports for Ca, Mg, Mn, SO4, and dissolved silica through the two mixing zones and small losses (< 10%) of colloidal Al, Fe and Zn from the water column.

This paper deals with a Liouville problem for the stationary fractional Navier-Stokes-Poisson system whose special case k=0 covers the compressible and incompressible time-independent fractional Navier-Stokes systems in R^{N≥2} . An essential difficulty raises from the fractional Laplacian, which is a non-local operator and thus makes the local analysis unsuitable. To overcome the difficulty, we utilize a recently-introduced extension-method in Wang and Xiao (Commun Contemp Math 18(6):1650019, 2016) which develops Caffarelli-Silvestre's technique in Caffarelli and Silvestre (Commun Partial Diff Equ 32:1245-1260, 2007).

The rates of dispersal and survival of sterile mass-reared laboratory flies and sterile wild flies of Anastrepha ludens (Loew) and Anastrepha obliqua (Macquart) were estimated and compared with a regular rectangular array of 64 food-baited traps spaced 60 m between traps around the release point in Tapachula Chiapas, Mexico. The traps were scored every day during the first week, and then every 3 d over a 30-d period. For A. obliqua, the number of males recaptured was higher than that of females, while for A. ludens, females were recaptured more frequently than males. The recapture rate for the wild strainsmore » ranged from 0.6-24.8% for A. ludens and 1.3-16.2% for A. obliqua and the corresponding ranges for the mass-reared strains were 0.5-7.1% and 0.5-3.0% respectively. The life expectancy was 4.7 d for wild and 4.3 d for mass-reared A. obliqua males but 3 and 2 d, respectively, for wild and mass-reared A. ludens males. The net displacement of A. ludens and A. obliqua ranged approximately from 100-250 m and took place mostly on the first day. Wild A. ludens moved to the northwest from the release point while the mass-reared strain moved to the west. The A. obliqua wild flies moved to the west, while the mass-reared strain shifted to the southwest. We discuss the implications of our findings as to the spacing and frequency of sterile fly releases for the suppression of wild populations.

Located in the southwestern corner of New Mexico, southern Hidalgo County occupies a segment of the Pedregosa sedimentary basin and is crossed by a belt of Laramide thrust faults. These factors favor accumulations of oil and gas. The present investigation has documented a constraint on probable oil and gas accumulations, the occurrence of major mid-Tertiary Valles-type ash-flow cauldrons and indications of underlying plutons. Indications of cauldrons have been found in the following ranges: in the southern Pyramid Mountains (Muir cauldron), south-central Peloncillo Mountains (Rodeo cauldron), Gaudalupe Mountains (Geronimo Trail cauldron), Sierra San Luis (San Luis cauldron), Southern Animas Mountains (Tullous,more » Animas Peak, Cowboy Rim cauldrons), Central Animas Mountains (Juniper cauldron), and Apache Hills (Apache cauldron). No indications of cauldrons or other major volcanic centers have been found in the southeastern corner of Hidalgo County, including the southern Sierra Rica, Big Hatchet Mountains, Alamo Hueco Mountains, and Dog Mountains. These cauldron-free areas offer the most favorable prospects for petroleum exploration.« less

Background: This study sought to assess the function and delivery reliability of intradermal (ID) infusion sets used with commercial insulin pumps. Method: Healthy subjects (n = 43) were randomized to either ID or subcutaneous (SC) arms, and received basal/bolus placebo delivery for 24 hours. Subjects received 4 of 8 infusion set combinations (ID: microneedle design A or B, with 2 pump brands [Animas or MiniMed]; SC: Teflon Quickset or steel Rapid-D, Animas pump only, with or without overtaping) and were evaluated for pump occlusion alarms, fluid leakage, pain, and tissue tolerability. A novel algorithm was developed to determine flow consistency based on fluid pressure, and the duration and occurrence rate for periods of unalarmed but interrupted flow (“silent occlusions’”) were compared. Results: ID delivery was successfully maintained over the 24-hour infusion period. The number of silent occlusions was lower for ID microneedle cannula design B than A (P < .01) and lower for Rapid-D SC device compared to Quick-set (P = .03). There was no significant difference in the number of occlusion alarms between the ID and SC devices with the Animas pump. However, the pumps tested with ID devices had significantly different alarm rates (MiniMed 29.5%, Animas 0%, P < .001). Leakage and tissue tolerability were comparable across devices. Conclusion: The ID infusion set reliably delivered diluent for an extended 24-hour period in healthy subjects and was well tolerated. Silent occlusion flow interruptions could be detected in both ID and SC infusion sets using a proprietary algorithm. This algorithm is a promising method for quantitatively evaluating infusion set flow performance. PMID:26319228
Geology and ore deposits of the South Silverton mining area, San Juan County, Colorado

The South Silverton mining area is immediately southeast of the town of Silverton, San Juan County, in southwestern Colorado (fig. 1). The town of Silverton itself lies in a relatively flat and open reach of the Animas Valley, called Bakers Park, in the western part of the San Juan Mountains. (See figs. 2 and 8.) The roughly circular area of the geologic map map (pl. 1) includes about 18½ square miles of the mountainous country southeast of Silverton. It is bounded on the west and north by the Animas River, on the east by Cunningham Creek, and on the south by Mountaineer Creek and Deer Park Creek. Altitudes range from 9,125 feet above sea level in the canyon of the Animas, at the southwest corner of the area, to 13,451 feet on Kendall Peak, 2¾ miles to the northeast.Within this area nearly a dozen horn-like peaks and sharp ridges separated by deep glacial cirques rise to altitudes of 13,000 feet or more. (See figs. 3, 7, 10, and 24.) Exposures are excellent along the crests and upper flanks of the ridges, but the bedrock along the lower parts of the valley walls and floors of the cirques is largely concealed by accumulations of talus. The timbered slopes along the south side of the Animas Valley are extensively covered with glacial moraine. Several of the high basins within the cirques hold ponds or small lakes; the largest is Silver Lake (fig. 23).Roads skirt the northern and eastern edges of the area but none give good access into the interior. Silverton is adjacent to U.S. Highway 550, which passes over the mountains by way of Red Mountain Pass from Ouray, 24 miles to the north, to Durango, 53 miles to the south. The community is also served by the narrow-gage line of the Denver and Rio Grande Western Railroad that follows the Animas River upstream from Durango. A gravel road, State Highway 110, follows the Animas River upstream, eastward from Silverton. From this highway a side road branches off to Cunningham Gulch as far as the Highland Mary mill, and

El objetivo de este documento esta dirigido a revisar el desempeno de las moscas esteriles frente a poblaciones silvestres procedentes de diferentes ambientes y para esto se realizaron comparaciones de compatibilidad y competitividad sexual de las moscas esteriles contra poblaciones silvestres de seis estados representativos de la Republica Mexicana: Nuevo Leon, Tamaulipas, Sinaloa, Nayarit, Michoacan y Chiapas. Los resultados obtenidos manifiestan diferencias en el horario de inicio de llamado y mayor actividad sexual del macho entre las moscas provenientes de cada estado. Sin embargo el indice de aislamiento (ISI) reflejo compatibilidad sexual entre la cepa de laboratorio y todas las poblaciones analizadas, indicando que los individuos esteriles pueden aparearse satisfactoriamente con las poblaciones silvestres de los seis estados. El indice de efectividad de apareamiento del macho (MRPI) reflejo de manera global que los machos esteriles son tan efectivos para copular como los silvestres. El indice de efectividad de apareamiento de la hembra (FRPI) reflejo que en la mayoria de los estados las hembras silvestres copularon en mayor proporcion que las hembras esteriles, excepto para las poblaciones de Tamaulipas y Chiapas. En general, la baja participacion de las hembras esteriles en el campo permitio al macho esteril ampliar su probabilidad de apareamiento con las hembras silvestres. En cuanto al indice de esterilidad relativa (RSI), observamos que la aceptacion de las hembras silvestres al macho esteril (25-55%) fue similar a la de los machos silvestres.

Mine planning efforts have historically overlooked the possible acid neutralizing capacity (ANC) that local igneous rocks can provide to help neutralize acidmine drainage. As a result, limestone has been traditionally hauled to mine sites for use in neutralizing acid drainage. Local igneous rocks, when used as part of mine life-cycle planning and acid mitigation strategy, may reduce the need to transport limestone to mine sites because these rocks can contain acid neutralizing minerals. Igneous hydrothermal events often introduce moderately altered mineral assemblages peripheral to more intensely altered rocks that host metal-bearing veins and ore bodies. These less altered rocks can contain ANC minerals (calcite-chlorite-epidote) and are referred to as a propylitic assemblage. In addition, the carbon contents of soils in areas of new mining or those areas undergoing restoration have been historically unknown. Soil organic carbon is an important constituent to characterize as a soil recovery benchmark that can be referred to during mine cycle planning and restoration.
This study addresses the mineralogy, ANC, and leachate chemistry of propylitic volcanic rocks that host polymetallic mineralization in the Animas River watershed near the historical Silverton, Colorado, mining area. Acid titration tests on volcanic rocks containing calcite (2 – 20 wt %) and chlorite (6 – 25 wt %), have ANC ranging from 4 – 146 kg/ton CaCO3 equivalence. Results from a 6-month duration, kinetic reaction vessel test containing layered pyritic mine waste and underlying ANC volcanic rock (saturated with deionized water) indicate that acid generating mine waste (pH 2.4) has not overwhelmed the ANC of propylitic volcanic rocks (pH 5.8). Sequential leachate laboratory experiments evaluated the concentration of metals liberated during leaching. Leachate concentrations of Cu-Zn-As-Pb for ANC volcanic rock are one-to-three orders of magnitude lower when compared to leached

This paper distinguishes between Jung's theoretical discourse regarding the archetypes and his phenomenological account of numinous experience. For this author, the initial attraction of 'my Jung' came from both the vivid Romanticism of his descriptions of the anima and the apparent 'ground of being' offered by his theory of archetypes. However, the essentialism inherent to archetypal theory in general and the anima in particular has necessitated a re-evaluation of Jung's theory in terms of emergence theory. My own version of this emphasises the role of symbols in the constitution of affect through collective human action in the world. In this reconfiguration, the visceral energy of numinous experience is retained while the problematic theory of archetypes is no longer needed. © 2018, The Society of Analytical Psychology.

The western US receives up to 80% of its annual streamflow from snowmelt fed river systems during the mid-to-late spring season. Changes in winter and spring air temperature and precipitation patterns have, however, begun to alter this sensitive hydroclimatological process, both in terms of the timing and magnitude of snowmelt events and the responding streamflow. Monitoring and planning for these changes in the future may well prove crucial for local water resource planners who traditionally rely on historical trends or means for water resource planning. Local-level water resource planners also often do not have the data or tools at the right resolution available to them for the same planning purposes. This goal of this research was to identify how changes in the local winter-spring climate may alter the hydrological response of a typical small mountain snowmelt fed river system, the Animas River in SW Colorado. To achieve this, a statistical downscaling technique was applied to increase the resolution of, and build a linear relationship between, historical upper atmospheric reanalysis data to surface level mean air temperature and precipitation for several climate stations located across the basin for 1950-2007. The same technique was then used to increase the resolution of two GCM scenarios from the NCAR CCSM3 model SRES-AR4 data runs (a 'business as usual’ or A1B scenario, and an increase in global greenhouse gas emissions or A2 scenario) using the same relationships between the historical upper atmospheric reanalysis data and the surface station climate data. Snowmelt streamflow magnitude and timing were then projected to 2099 based on their historical relationship to mean monthly winter and spring air temperature and precipitation before being compared to the historical averages. Results indicated a shift in the timing of the snowmelt streamflow to earlier in the spring, and a reduction in the magnitude of peak spring streamflow following increasing spring

presumed to be impacted by historical mining activities. The Animas River watershed (fig. 1) was selected by the State and Federal agencies as one of two watersheds in the U.S. to be studied in detail by the USGS in the AML Initiative. Beginning in October 1997, each of the four Divisions of the USGS (Water Resources, Geologic, Biological Resources, and National Mapping) initiated a collaborative integrated science study of the watershed. Funds were provided from USGS base funding to each of the four Divisions in response to the priorities set by Congressional action and within the flexibility provided by the budgetary framework funding individual research programs. The AML Initiative provides for a five-year focused scientific effort in the two watersheds with final synthesis of the scientific results from each to be published in 2001. Publications are released on the AML web site on a regular basis (http://amli.usgs.gov/amli). On March 29, 2000, the USGS hosted a meeting for the BLM and USFS to discuss remediation options that were under consideration for the summer of 2000. The purpose of this report is to provide an overview of the scientific rational provided by the USGS to meet objective one above, and to summarize our preliminary interpretations of our data. Additional information from sites on private lands have been collected by the State of Colorado, EPA, and the ARSG. Unfortunately, these data have not been fully supplied to the USGS so our conclusions are based only upon our data. These interpretations provide science-based constraints on possible remediation options to be considered by the FLMA, the State, and local property owners in the Animas River watershed. The report is presented in outline format to facilitate discussion of remediation options at the March 29, 2000 meeting. Not all historical mining sites within the watershed are on public lands. This should not be construed to be a final report of the USGS

The Raton Basin in southern Colorado and northern New Mexico is undergoing increased development of its coalbed-methane resources. Annual production of methane from coalbeds in the Raton Basin in Huerfano and Las Animas Counties, Colorado, increased from about 28,000,000 thousand cubic feet from 478 wells to about 80,000,000 thousand cubic feet from 1,543 wells, during 1999-2004. Annual ground-water withdrawals for coalbed-methane production increased from about 1.45 billion gallons from 480 wells to about 3.64 billion gallons from 1,568 wells, during 1999-2004. Where the coalbeds are deeply buried near the center of the Raton Basin, water pressure may be reduced as much as 250 to 300 pounds per square inch to produce the methane from the coalbeds, which is equivalent to a 577- to 692-foot lowering of water level. In 2001, the U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board, began an evaluation of the potential effects of coalbed- methane production on the availability and sustainability of ground-water resources. In 2003, there were an estimated 1,370 water-supply wells in the Raton Basin in Colorado, and about 90 percent of these water-supply wells were less than 450 feet deep. The tops of the production (perforated) interval of 90 percent of the coalbed-methane wells in the Raton Basin (for which data were available) are deeper than about 675 feet. The potential for interference of coalbed-methane wells with nearby water-supply wells likely is limited because in most areas their respective production intervals are separated by more than a hundred to a few thousand feet of rock. The estimated vertical separation between production intervals of coalbed-methane and water-supply wells is less than 100 feet in an area about 1 to 6 miles west and southwest of Trinidad Lake and a few other isolated areas. It is assumed that in areas with less than 100 feet of vertical separation, production by coalbed-methane wells has a greater

Abstract A new species of palm-pitviper of the genus Bothriechis is described from Refugio de Vida Silvestre Texíguat in northern Honduras. The new species differs from congeners by having 19 dorsal scale rows at midbody, a bright green dorsal coloration in adults, the prelacunal scale fused to the second supralabial, and in representing a northern lineage that is sister to Bothriechis lateralis, which is distributed in Costa Rica and western Panama and is isolated from the new taxon by the Nicaraguan Depression. This represents the 15th endemic species occurring in Refugio de Vida Silvestre Texíguat, one of the richest herpetofaunal sites in Honduras, itself being the country with the highest degree of herpetofaunal endemism in Central America. We name this new species in honor of a Honduran conservationist slain in fighting against illegal logging, highlighting the sacrifices of rural activists in battling these issues and the critical importance of conservation in these areas.

This report presents results from laboratory and field studies involving the net acid production (NAP), acid neutralizing capacity (ANC), and magnetic mineralogy of 27 samples collected in altered volcanic terrain in the upper Animas River watershed near Silverton, Colo., during the summer of 2005. Sampling focused mainly on the volumetrically important, Tertiary-age volcanic and plutonic rocks that host base- and precious-metal mineralization in the study area. These rocks were analyzed to determine their potential for neutralization of acid-rock drainage. Rocks in the study area have been subjected to a regional propylitic alteration event, which introduced calcite, chlorite (clinochlore), and epidote that have varying amounts and rates of acid neutralizing capacity (ANC). Locally, hydrothermal alteration has consumed any ANC and introduced minerals, mainly pyrite, that have a high net acid production (NAP). Laboratory studies included hydrogen pyroxide (H2O2) acid digestion and subsequent sodium hydroxide (NaOH) titration to determine NAP, and sulfuric acid (H2SO4) acid titration experiments to determine ANC. In addition to these environmental rock-property determinations, mineralogical, chemical, and petrographic characteristics of each sample were determined through semiquantitative X-ray diffractometry (Rietveld method), optical mineralogy, wavelength dispersive X-ray fluorescence, total carbon-carbonate, and inductively coupled plasma?mass spectrometric analysis. An ANC ranking was assigned to rock samples based on calculated ANC quantity in kilograms/ton (kg/t) calcium carbonate equivalent and ratios of ANC to NAP. Results show that talus near the southeast Silverton caldera margin, composed of andesite clasts of the Burns Member of the Silverton Volcanics, has the highest ANC (>100 kg/t calcium carbonate equivalent) with little to no NAP. The other units found to have moderate to high ANC include (a) andesite lavas and volcaniclastic rocks of the San Juan

On August 5, 2015, approximately 3 million gallons of acid mine drainage were released from the Gold King Mine into Cement Creek in the San Juan River watershed (CO, NM, UT). The release further mobilized additional metals, which resulted in a large mass of solids and dissolved metals entering Cement Creek. These metals were released into the Animas River. As the release acidity was neutralized, the metals precipitated and formed the visually noticeable "yellow boy," which flowed down the San Juan River. We applied the Water Quality Analysis Simulation Program (WASP) using empirically based parameterization to simulate and describe the movement of the plume and total and dissolved concentrations of all metals, including Arsenic, Copper, Lead, and Zinc. We estimated that the plume took between approximately 1 to 3 days to pass any given location. The peak concentration of the plume took about 2 hours to reach Silverton, CO (16 rkm), 1.5 days to reach Durango, CO (94 rkm), 2.9 days to reach Farmington, NM, (190 rkm) and 5.8 days to reach Mexican Hat, UT (422 km). Total metal concentration decreased rapidly going downstream, dropping 80% upon entering the Animas at Silverton, CO, and 99.5% entering the San Juan at Farmington. Metal concentrations decreased by dilution, settling, and dispersion. Modeling suggests that deposition occurred primarily in the upper Animas River near Silverton and near Durango, which was supported with empirical evidence. This work demonstrates the utility of a combined empirical and mechanistic modeling analysis. We additionally investigate long-term residual effects and potential exposure concentrations during storm and snowmelt high flow periods after the visible plume had traversed the system.

The acidic discharge from Cement Creek, containing elevated concentrations of dissolved metals and sulphate, mixed with the circumneutral-pH Animas River over a several hundred metre reach (mixing zone) near Silverton, CO, during this study. Differences in concentrations of Ca, Mg, Si, Sr, and SO42- between the creek and the river were sufficiently large for these analytes to be used as natural tracers in the mixing zone. In addition, a sodium chloride (NaCl) tracer was injected into Cement Creek, which provided a Cl- reference tracer in the mixing zone. Conservative transport of the dissolved metals and sulphate through the mixing zone was verified by mass balances and by linear mixing plots relative to the injected reference tracer. At each of seven sites in the mixing zone, five samples were collected at evenly spaced increments of the observed across-channel gradients, as determined by specific conductance. This created sets of samples that adequately covered the ranges of mixtures (mixing ratios, in terms of the fraction of Animas River water, %AR). Concentratis measured in each mixing zone sample and in the upstream Animas River and Cement Creek were used to compute %AR for the reference and natural tracers. Values of %AR from natural tracers generally showed good agreement with values from the reference tracer, but variability in discharge and end-member concentrations and analytical errors contributed to unexpected outlier values for both injected and natural tracers. The median value (MV) %AR (calculated from all of the tracers) reduced scatter in the mixing plots for the dissolved metals, indicating that the MV estimate reduced the effects of various potential errors that could affect any tracer.
Earth Observations taken by the Expedition 15 Crew

ISS015-E-07928 (13 May 2007) --- Isla San Lorenzo and Isla Las Animas are featured in this image photographed by an Expedition 15 crewmember on the International Space Station. Located in the northern Gulf of California, Isla (island) San Lorenzo and Isla Las Animas -- part of the Midriff Islands -- record geologic processes involved in the creation of the Baja California peninsula over several hundred million years, according to scientists. A geologist walking along the 17-kilometer long central ridge of Isla San Lorenzo from the southeastern to the northwestern end would first encounter Cretaceous granitic rock in the southeastern third of the island (light tan, center left). The central third of the island is comprised mainly of older Paleozoic metamorphic rocks (brown, center; directly above "Isla San Lorenzo"). Together, these very old rocks form the crystalline "basement" of the island. The northwestern third of Isla San Lorenzo, and much of adjacent Isla Las Animas, is composed of much more recent volcanic and marine sedimentary rocks (yellow-brown to light brown, center right). According to scientists, these rocks were formed by volcanoes and fissure eruptions in and around basins in the growing Gulf of California between 5-8 million years ago. The islands themselves were formed as a result of uplift of crustal blocks along the southeastward-trending San Andreas Fault. This image illustrates the largely pristine nature of these islands. The islands are located in the rain shadow of mountains on the Baja Peninsula to the west, and arid conditions prevail through much of the year. The scarcity of water has limited human presence on the islands, and allowed flora and fauna unique to each island (known as endemic species) to flourish -- particularly reptiles. The islands are also home to colonies of seabirds and seals, both of which take advantage of deep productive waters adjacent to the eastern Baja coast. Shallow waters and high levels of nutrients can also

The Casas Grandes area in Chihuahua, Mexico and the site of Paquime was the center of one the largest regional systems in the U.S. Southwest and Mexican Northwest (SW/NW) during the Medio period (CE 1200-1450). People participated in local and distant exchange networks with groups in the SW/NW, Mesoamerica, and West Mexico. Our knowledge of which obsidian sources people used in Casas Grandes is limited, despite how obsidian could have derived from many different places. We examine how the use of specific obsidian sources may relate to broader political and economic relationships within the Casas Grandes regional system and itsmore » association with the Mimbres and Animas regions of the SW/NW. We sourced 116 artifacts using EDXRF spectrometry from four sites that neighbor Paquime. Results demonstrate people used obsidian from Chihuahua, Sonora, and New Mexico. Furthermore, there were varying levels of social interaction and regional integration because there is diversity in source use at the site level, and Casas Grandes were more connected to the Animas region than Mimbres regarding obsidian resource procurement.« less

The Casas Grandes area in Chihuahua, Mexico and the site of Paquime was the center of one the largest regional systems in the U.S. Southwest and Mexican Northwest (SW/NW) during the Medio period (CE 1200-1450). People participated in local and distant exchange networks with groups in the SW/NW, Mesoamerica, and West Mexico. Our knowledge of which obsidian sources people used in Casas Grandes is limited, despite how obsidian could have derived from many different places. We examine how the use of specific obsidian sources may relate to broader political and economic relationships within the Casas Grandes regional system and itsmore » association with the Mimbres and Animas regions of the SW/NW. We sourced 116 artifacts using EDXRF spectrometry from four sites that neighbor Paquime. Results demonstrate people used obsidian from Chihuahua, Sonora, and New Mexico. Furthermore, there were varying levels of social interaction and regional integration because there is diversity in source use at the site level, and Casas Grandes were more connected to the Animas region than Mimbres regarding obsidian resource procurement.« less

Congenital eye malformations are the second most common cause of childhood blindness and are originated by disruption of the normal process of eye development during embryonic stage. Their etiology is variable, although monogenic causes are of great importance as they have a high risk of familial recurrence. Included among the most severe congenital eye abnormalities are microphthalmia, defined by an abnormally small eye, and anophthalmia, characterized by congenital absence of ocular structures. The currrent knowledge of the genes involved in human microphthalmia and anophthalmia in humans is revised in this work. Copyright: © 2017 SecretarÍa de Salud.

Illustration of a fingerprinting method to isolate Gold King ...
Detecting the Gold King Mine metals as the release plume passed was difficult once it entered the San Juan River on August 8, 2015. Plume metals concentrations were relatively low after 200 km of travel and deposition in the Animas River while background concentrations of the same metals were high due to high sediment load in the San Juan River. A metal fingerprinting technique was used to isolate metals in the Gold King release from background using the measured concentrations of the 23 TAL metals (Metal/Cynaide Target Analyte List) available with most water samples. The method associates the concentration of trace metals to that of aluminum or iron as representative of the dominant metals in the geologic substrate. Metal concentrations can be plotted together, as in Figure 1A, or the ratio can be computed for each sample for use as a value, such as plotted in time in Figure 1B. The correlation technique allowed maximum use of typically available water sample data to isolate Gold King metals as contaminants within the varying background concentrations associated with the natural sediments of the San Juan River. To be presented at the New Mexico Water Institute Symposium, 2nd Annual Conference on Environmental Conditionsof the Animas and San Juan Watersheds with Emphasis on Gold King Mine and Other Mine Waste Issues.

The South American sea lion, Otaria flavescens, is widely distributed along the Pacific and Atlantic coasts of South America. However, along the Brazilian coast, there are only two nonbreeding sites for the species (Refúgio de Vida Silvestre da Ilha dos Lobos and Refúgio de Vida Silvestre do Molhe Leste da Barra do Rio Grande), both in Southern Brazil. In this region, the species is continuously under the effect of anthropic activities, mainly those related to environmental contamination with organic and inorganic chemicals and fishery interactions. This paper reports, for the first time, the genetic diversity of O. flavescens found along the Southern Brazilian coast. A 287-bp fragment of the mitochondrial DNA control region (D-loop) was analyzed. Seven novel haplotypes were found in 56 individuals (OFA1-OFA7), with OFA1 being the most frequent (47.54%). Nucleotide diversity was moderate (π = 0.62%) and haplotype diversity was relatively low (67%). Furthermore, the median joining network analysis indicated that Brazilian haplotypes formed a reciprocal monophyletic clade when compared to the haplotypes from the Peruvian population on the Pacific coast. These two populations do not share haplotypes and may have become isolated some time back. Further genetic studies covering the entire species distribution are necessary to better understand the biological implications of the results reported here for the management and conservation of South American sea lions.

With an exactly solvable O(4) model of Piepenbring, Silvestre-Brac and Szymanski, we demonstrate that the attenuation factor for the B(E2) values, derived by the lowest-order approximation of the multiphonon method, takes excellent care of the kinematical anharmonicity effects, if multiphonon states are defined in the intrinsic subspace orthogonal to the pairing rotation. It is also shown that the other attenuation effect characterizing the interacting boson model is not a dominant effect in the model analysed here.

Unconsolidated late Cenozoic deposits in the northern part of the San Juan Basin range in age from late Pliocene to Holocene. Most of the deposits are alluvial gravel composed of resistant quartzite, sandstone, and igneous, metamorphic, and volcanic rocks derived from the uplifted central core of the San Juan Mountains 20-50 miles (32-80 kilometers) north of the basin. Alluvial deposits are most voluminous in the Animas Valley, but deposits of gravel of the same general age are present in the La Plata, Florida, Los Pinos, and Piedra River valleys as well. Alluvial gravel forms tabular deposits, generally about 20 feet (6 meters) thick, that are exposed beneath a sequence of terraces at many levels above the rivers. Gravel layers 360 feet (110 meters) or less above the Animas River are glacial outwash. The gravel layers begin at the south toes of end moraines and extend discontinuously downvalley at least 10-20 miles (16-32 kilometers). Farther south, distinction between outwash and nonglacial alluvium is problematical. Alluvial gravel beneath higher terraces does not grade to end moraines. Glacial till forms a series of end moraines at the north edge of the town of Durango. The oldest moraines are farthest downvalley, are higher above the river, and have more mature surficial soils than do moraines farther north. The two youngest moraines, the Animas City moraines, are interpreted to be Pinedale in age. They have narrow, ridgelike crests and form nearly unbroken arcs across the valley floor. Small segments of still more weathered moraines, the Spring Creek moraines, are 170-230 feet (52-70 meters) above the river and are 660-990 feet (200-300 meters) farther downvalley. The oldest moraines, the Durango moraines, are on the north end of the unnamed mesa on which Fort Lewis College is located. The base is about 180 feet (55 meters) above the river. These oldest moraines may be of Bull Lake age. Alluvial fans, pediment gravel, and landslides are scattered at several
Assessment of historical surface-water quality data in southwestern Colorado, 1990-2005
Miller, Lisa D.; Schaffrath, Keelin R.; Linard, Joshua I.
2013-01-01
The spatial and temporal distribution of selected physical and chemical surface-water-quality characteristics were analyzed at stream sites throughout the Dolores and San Juan River Basins in southwestern Colorado using historical data collected from 1990 through 2005 by various local, State, Tribal, and Federal agencies. Overall, streams throughout the study area were well oxygenated. Values of pH generally were near neutral to slightly alkaline throughout most of the study area with the exception of the upper Animas River Basin near Silverton where acidic conditions existed at some sites because of hydrothermal alteration and(or) historical mining. The highest concentrations of dissolved aluminum, total recoverable iron, dissolved lead, and dissolved zinc were measured at sites located in the upper Animas River Basin. Thirty-two sites throughout the study area had at least one measured concentration of total mercury that exceeded the State chronic aquatic-life criterion of 0.01 μg/L. Concentrations of dissolved selenium at some sites exceeded the State chronic water-quality standard of 4.6 μg/L. Total ammonia, nitrate, nitrite, and total phosphorus concentrations generally were low throughout the study area. Overall, results from the trend analyses indicated improvement in water-quality conditions as a result of operation of the Paradox Valley Unit in the Dolores River Basin and irrigation and water-delivery system improvements made in the McElmo Creek Basin (Lower San Juan River Basin) and Mancos River Valley (Upper San Juan River Basin).
Hydrology of coal-lease areas near Durango, Colorado
Brooks, Tom
1985-01-01
The U.S. Bureau of Land Management leases Federal lands and minerals for coal mining near Durango, Colorado. This report addresses the hydrologic suitability of those lands for coal leasing; the report describes the general hydrology of the Durango area and, more specifically, the hydrology of the Stollsteimer Creek study area 32 miles east of the Durango and the Hay Gulch study area, 12 miles southwest of Durango. The most productive aquifers in the Durango study area are Quaternary alluvium and the tertiary Animas Formation. Water wells completed in alluvium typically yield 5 to 20 gallons/min; wells completed is the Animas Formation yield as much as 50 gallons/min. Water quality in these aquifers is variable, but it generally is suitable for domestic use. The coal-bearing Cretaceous Fruitland and Menefee Formations are mined by surface methods at the Chimney Rock Mine in the Stollsteimer Creek study area and by underground methods at the National King Coal Mine in the Hay Gulch study area. Effects of surface mining in the Stollsteimer Creek area are: (1) Dewatering of an alluvial aquifer; and (2) Local degradation of alluvium water quality by spoil-pile effluent. Effects of underground mining in the Hay Gulch area are: (1) Introduction of water with greater dissolved-solids concentrations into the upper Hay Gulch alluvium from mine runoff; (2) Subsidence fracturing which could dewater streams and the alluvial aquifer.

Mary Shelley's Frankenstein is perhaps the most famous work of medical science fiction. She and her husband, the poet Percy Shelley, were aware of nascent neuroscience experimentation and the effects of electricity on neuromuscular function. Such experiments generated theories of voluntary, involuntary, and unconscious neuromuscular function; animal electricity; and the anima--the human vital principle. In Germany and Italy, investigators were performing bizarre electrical experiments on animals and humans to "reanimate" lifeless limbs and bodies. These demonstrations and theories find expression in Frankenstein and provide models for Dr. Frankenstein and his creation.

Daily rainfall and surface temperature series were simulated for the Animas River basin, Colorado using dynamically and statistically downscaled output from the National Center for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) re-analysis. A distributed hydrological model was then applied to the downscaled data. Relative to raw NCEP output, downscaled climate variables provided more realistic stimulations of basin scale hydrology. However, the results highlight the sensitivity of modeled processes to the choice of downscaling technique, and point to the need for caution when interpreting future hydrological scenarios.

The Gold King mine water release that occurred on 5 August 2015 near the historical mining community of Silverton, Colorado, highlights the environmental legacy that abandoned mines have on the environment. During reclamation efforts, a breach of collapsed workings at the Gold King mine sent 3 million gallons of acidic and metal-rich mine water into the upper Animas River, a tributary to the Colorado River basin. The Gold King mine is located in the scenic, western San Juan Mountains, a region renowned for its volcano-tectonic and gold-silver-base metal mineralization history. Prior to mining, acidic drainage from hydrothermally altered areas was a major source of metals and acidity to streams, and it continues to be so. In addition to abandoned hard rock metal mines, uranium mine waste poses a long-term storage and immobilization challenge in this area. Uranium resources are mined in the Colorado Plateau, which borders the San Juan Mountains on the west. Uranium processing and repository sites along the Animas River near Durango, Colorado, are a prime example of how the legacy of mining must be managed for the health and well-being of future generations. The San Juan Mountains are part of a geoenvironmental nexus where geology, mining, agriculture, recreation, and community issues converge. This trip will explore the geology, mining, and mine cleanup history in which a community-driven, watershed-based stakeholder process is an integral part. Research tools and historical data useful for understanding complex watersheds impacted by natural sources of metals and acidity overprinted by mining will also be discussed.

The U.S. Geological Survey, using a geoscience-based assessment methodology, estimated mean technically-recoverable undiscovered continuous and conventional resources that total 495 million barrels of oil, 27.5 trillion cubic feet of natural gas, and 410 million barrels of natural gas liquids in the Anadarko Basin Province; this assessment includes the Las Animas arch area of southeastern Colorado. The province is at a mature stage of exploration and development for conventional resources. Mean undiscovered continuous resources are estimated at 79 percent of oil, 90 percent of natural gas, and 81 percent of natural gas liquids in the province.
Controlling cytoplasmic c-Fos controls tumor growth in the peripheral and central nervous system.
Gil, Germán A; Silvestre, David C; Tomasini, Nicolás; Bussolino, Daniela F; Caputto, Beatriz L
2012-06-01
Some 20 years ago c-Fos was identified as a member of the AP-1 family of inducible transcription factors (Angel and Karin in Biochim Biophys Acta 1072:129-157, 1991). More recently, an additional activity was described for this protein: it associates to the endoplasmic reticulum and activates the biosynthesis of phospholipids (Bussolino et al. in FASEB J 15:556-558, 2001), (Gil et al. in Mol Biol Cell 15:1881-1894, 2004), the quantitatively most important components of cellular membranes. This latter activity of c-Fos determines the rate of membrane genesis and consequently of growth in differentiating PC12 cells (Gil et al. in Mol Biol Cell 15:1881-1894, 2004). In addition, it has been shown that c-Fos is over-expressed both in PNS and CNS tumors (Silvestre et al. in PLoS One 5(3):e9544, 2010). Herein, it is shown that c-Fos-activated phospholipid synthesis is required to support membrane genesis during the exacerbated growth characteristic of brain tumor cells. Specifically blocking c-Fos-activated phospholipid synthesis significantly reduces proliferation of tumor cells in culture. Blocking c-Fos expression also prevents tumor progression in mice intra-cranially xeno-grafted human brain tumor cells. In NPcis mice, an animal model of the human disease Neurofibromatosis Type I (Cichowski and Jacks in Cell 104:593-604, 2001), animals spontaneously develop tumors of the PNS and the CNS, provided they express c-Fos (Silvestre et al. in PLoS One 5(3):e9544, 2010). Treatment of PNS tumors with an antisense oligonucleotide that specifically blocks c-Fos expression also blocks tumor growth in vivo. These results disclose cytoplasmic c-Fos as a new target for effectively controlling brain tumor growth.
[Tertullianus and Agostinus. Approaches to dreams in ancient Christianity].
Genovese, Armando
2009-01-01
The author analyzes the nature and typologies of dreams in Tertullianus' De anima and, briefly, in the work of Agostinus, two centuries later. What are made dreams of? Are they autonomous productions of psyché or phantasia, or rather messages sent by demons or God, according to dreams' bad or good intimate nature? Is there a relation between time of the night and nature of the dreams? Moreover, is there a relation between seasons and dreams? Does a specific relationship between food, regimen and dreams exist? Which is the soul's faculty able to generate dreams? Is phantasia moved by some other deep and mysterious principle? Which are the connections linking human physiology and dreams?

Describe the coding process of death causes for people living with HIV/AIDS, and classify deaths as related or unrelated to immunodeficiency by applying the Coding Causes of Death in HIV (CoDe) system. A cross-sectional study that codifies and classifies the causes of deaths occurring in a cohort of 2,372 people living with HIV/AIDS, monitored between 2007 and 2012, in two specialized HIV care services in Pernambuco. The causes of death already codified according to the International Classification of Diseases were recoded and classified as deaths related and unrelated to immunodeficiency by the CoDe system. We calculated the frequencies of the CoDe codes for the causes of death in each classification category. There were 315 (13%) deaths during the study period; 93 (30%) were caused by an AIDS-defining illness on the Centers for Disease Control and Prevention list. A total of 232 deaths (74%) were related to immunodeficiency after application of the CoDe. Infections were the most common cause, both related (76%) and unrelated (47%) to immunodeficiency, followed by malignancies (5%) in the first group and external causes (16%), malignancies (12 %) and cardiovascular diseases (11%) in the second group. Tuberculosis comprised 70% of the immunodeficiency-defining infections. Opportunistic infections and aging diseases were the most frequent causes of death, adding multiple disease burdens on health services. The CoDe system increases the probability of classifying deaths more accurately in people living with HIV/AIDS.

RESUMEN El estigma relacionado al VIH/SIDA continúa afectando la prestación de servicios de salud y el bienestar físico y mental de las personas con VIH/SIDA (PVS). Recientemente la literatura científica ha señalado la importancia de comprender las manifestaciones de estigma más allá de las interacciones individuales. Por tal razón, investigaciones recientes en y fuera de Puerto Rico enfatizan la importancia de entender cómo factores socio-estructurales (FSE) influyen en los procesos de estigmatización social. Con el propósito de examinar los FSE que influyen en las manifestaciones de estigma relacionado al VIH/SIDA, realizamos y analizamos nueve grupos focales compuestos por hombres y mujeres en tratamiento para el VIH/SIDA que habían tenido experiencias estigmatizantes. Los participantes identificaron FSE relacionados a las manifestaciones de estigma, tales como el uso de viviendas especializadas, descentralización de los servicios de salud y el desarrollo de protocolos administrativos excluyentes en los servicios de salud. Los resultados demuestran la importancia de considerar los FSE en el desarrollo e implementación de intervenciones dirigidas a la población. PMID:24639599

Light-seeds within: The alchemy of re-finding light in the world soul
NASA Astrophysics Data System (ADS)
Erickson, Stacy Lynn
The light of the Anima Mundi has been repressed for over two thousand years. From a feminine in-sighting, this dissertation considers the reasons for the World Soul's repression and how her light can be renewed. The division of body and mind, image and word, physicality and spirituality, as well as nature and science has been costly, though this time of crisis also holds great opportunity to change perspective and live differently. The art of alchemy contains the secrets to transform elements in opposition into those in relationship in order to give birth to something new. Where feminine and masculine have been divorced and divided, the 'Royal Art' of alchemy seeks to renew soul in the world as an experience of life's interconnectivity and as a sacred marriage of matter and spirit. Through the four elements and three alchemical stages, this journey articulates the amorphous unconscious to evolve the light within the body of the microcosm and the macrocosm. The study's phenomenological perspective merges creative imagination with experiential gnosis in an exploration of the rich tapestry and mystery of an esoteric tradition. Through dream tending and active imagination, one connects to the subtle body, the imaginal world, and mythological regions with archetypal energies where elemental symbols are seeds. When cultivated and tended, these seeds grow into embodied feelings, visceral happenings. These experiential moments contain the revelations necessary for personal and global transmutation. Alchemy's tenet of 'as above, so below' holds a simple truth. When an individual works on her light, the Anima Mundi's light grows brighter. The alchemical process awakens love as the animating essence, the divine spark within the heart of all life---the gold in every atom of creation. Where matter and spirit conjoin, the hierosgamos reveals life's divine nature as an intimate dance and a web of interconnectivity. When lived for the sake of the whole and seen with the eyes of an

I'd like to talk a little bit about another important disturbance regime in much of the western United States and Mexico. We've talked some about the importance of fire. Another one is the importance of natural hydrological cycles. But an often-overlooked important ecological disturbance regime is predation. Research around the world and in many habitats has...

To evaluate the relation between diabetes-related distress and the clinical and sociodemographic characteristics of type 2 diabetes mellitus patients. A cross-sectional study based on a secondary analysis of data collected at a specialized care outpatient center in Brazil. Participants completed a questionnaire on sociodemographic and clinical characteristics and the Brazilian version of the Diabetes Distress Scale (B-DDS). About 31% of the 130 eligible patients reported diabetes distress, and the mean B-DDS score was 2.6. Multiple regression analysis showed the B-DDS score was positively correlated with marital status (p=0.0230), use of diet and physical activities for diabetes management (p=0.0180), and use of insulin therapy (p=0.0030). The "emotional burden", "regimen-related distress", and "interpersonal distress" domains from B-DDS were associated with the use of insulin therapy (p=0.0010), marital status (p=0.0110), and the presence of three or more comorbidities (p=0.0175). These findings suggest the clinical and sociodemographic variables are relatively weak predictors of diabetes-related distress. The highest scores in the B-DDS were observed in the emotional burden domain, indicating the presence of diabetes distress among the participants of the study.

Hydrology of the U.S. Army Pinon Canyon maneuver site, Las Animas County, Colorado
Von Guerard, Paul; Abbott, P.O.; Nickless, Raymond C.
1987-01-01
The U.S. Department of the Army (Fort Carson Military Reservation) has acquired 381 sq mi of semiarid rangeland in southeastern Colorado for mechanized military maneuvers. The study area, known as the Pinon Canyon Maneuver Site, drains into the Purgatoire River, a major tributary of the upper Arkansas River. A multidisciplined hydrologic investigation began in October 1982. The primary aquifer in the Maneuver Site is the Dakota-Purgatoire. Well yields generally range from 10 to 500 gal/min. Dissolved solids concentrations in groundwater ranged from 195 to 6,150 mg/L. Streamflow in the Purgatoire River is perennial. Tributaries draining the Maneuver Site are intermittent or ephemeral and contribute only about 4.4% of the streamflow of the Purgatoire River downstream from the Maneuver Site. Flood frequencies were calculated by using the log Pearson III procedure and compared well with a regional estimating technique that was developed that uses physical drainage-basin characteristics. Calcium and sulfate are the predominant ions in the surface water of the area. Time-series plots indicate that instream water-quality standards for nitrate and metals are exceeded. About 80% of the suspended-sediment load is transported by rainfall runoff, which occurs less than 8% of the time. Ephermal tributaries contributed less than 25% of the suspended-sediment load transported to the Purgatoire River downstream from the Maneuver Site. Historic annual mean sediment yields were measured for 29 small watersheds. Sediment yields were measured for 29 small watersheds. Sediment yields ranged from 9.5 to 1,700 tons/sq mi. Sediment yields were estimated by a multiple-linear-regression model developed by using physical drainage-basin characteristics and by the Pacific Southwest Interagency Committee method. (USGS)
Birds and people in semiarid northeastern Brazil: symbolic and medicinal relationships
2013-01-01
Abstract Background At least 511 species of birds occur in the semiarid region of northeastern Brazil and many of them interact with human populations in a number of different ways, including their use in zootherapeutics and their links with local beliefs. Objective The present work examined these types of birds/human interactions (use in zootherapeutics and their links with local beliefs) in the semiarid region of Rio Grande do Norte State in northeastern Brazil. Methods Information was obtained through semi-structured interviews with 120 local residents. Results A total of 16 wild bird species distributed among 11 families were found to interact directly with humans, with Columbidae being the best represented family. Seven species were identified in the medicinal category, five were related to symbolic aspects, while four species were identified as being related to both categories (medicinal and symbolic). Conclusion The accumulated folk knowledge, beliefs, and practices involving the avifauna in the semiarid region of Brazil, whether symbolic or medicinal, demonstrated the cultural importance of this vertebrate group to local human populations and revealed a belief system intrinsically related to cynegetic practices in the region.

Transgenderism and transformation: an attempt at a Jungian understanding.
Marsman, Michael A
2017-11-01
While transgenderism as a cultural phenomenon seems to be based on a collective taste for the sensational, its emergence represents a collective shift towards a new or more differentiated way of experiencing and expressing sex and gender, a movement of world soul. This paper attempts to explore that emergence from a Jungian perspective. The paper utilizes clinical examples which illustrate how dissociated aspects of the personality are seeking assimilation and expression in order to move the personality towards greater wholeness. In that sense, it attempts to understand the teleology of transgenderism on an individual and collective level. The paper is intended as a starting-off point for discussion and explores gender as fantasy, anima/animus dynamics, the psyche/soma relationship, the role of hormones/biochemistry in our experience of ourselves and what transgender people carry and suffer for our culture. © 2017, The Society of Analytical Psychology.
Ancient maize from Chacoan great houses: Where was it grown?

In this article, we compare chemical (87Sr/86Sr and elemental) analyses of archaeological maize from dated contexts within Pueblo Bonito, Chaco Canyon, New Mexico, to potential agricultural sites on the periphery of the San Juan Basin. The oldest maize analyzed from Pueblo Bonito probably was grown in an area located 80 km to the west at the base of the Chuska Mountains. The youngest maize came from the San Juan or Animas river floodplains 90 km to the north. This article demonstrates that maize, a dietary staple of southwestern Native Americans, was transported over considerable distances in pre-Columbian times, a finding fundamental to understanding the organization of pre-Columbian southwestern societies. In addition, this article provides support for the hypothesis that major construction events in Chaco Canyon were made possible because maize was brought in to support extra-local labor forces.

Bau, Haim; Yuan, Jinzhou; Raizen, David
2015-11-01
Since the propulsive thrust of micro organisms provides a more sensitive indicator of the animal's health and response to drugs than motility, a simple, high throughput, direct measurement of the thrust is desired. Taking advantage of the nematode C. elegans being heavier than water, we devised a simple method to determine the propulsive thrust of the animals by monitoring their velocity when swimming along an inclined plane. We find that the swimming velocity is a linear function of the sin of the inclination angle. This method allows us to determine, among other things, the animas' propulsive thrust as a function of genotype, drugs, and age. Furthermore, taking advantage of the animals' inability to swim over a stiff incline, we constructed a sawteeth ratchet-like track that restricts the animals to swim in a predetermined direction. This research was supported, in part, by NIH NIA Grant 5R03AG042690-02.

Results of a radiological survey of the inactive uranium-mill site at Durango, Colorado, conducted in April 1976, in cooperation with a team from Ford, Bacon and Davis Utah Inc., are presented together with descriptions of the instruments and techniques used to obtain the data. Direct above-ground gamma measurements and analysis of surface soil and sediment samples indicate movement of tailings from the piles toward Lightner Creek on the north and the Animas River on the east side of the piles. The concentration of /sup 226/Ra in the former raffinate pond area is only slightly above the background level. Two structuresmore » in Durango were found to contain high concentrations of airborne radon daughters, where tailings are known to have been utilized in construction. Near-background concentrations of radon daughters were found in a well-ventilated building close to the tailings.« less

A Liouville type theorem for Lane-Emden systems involving the fractional Laplacian
NASA Astrophysics Data System (ADS)
Quaas, Alexander; Xia, Aliang
2016-08-01
We establish a Liouville type theorem for the fractional Lane-Emden system: {(-Δ)αu=vqin RN,(-Δ)αv=upin RN, where α \\in (0,1) , N>2α and p, q are positive real numbers and in an appropriate new range. To prove our result we will use the local realization of fractional Laplacian, which can be constructed as a Dirichlet-to-Neumann operator of a degenerate elliptic equation in the spirit of Caffarelli and Silvestre (2007 Commun. PDE 32 1245-60). Our proof is based on a monotonicity argument for suitable transformed functions and the method of moving planes in a half infinite cylinder ({IR}× S+N , where S+N is the half unit sphere in {{{R}}N+1} ) based on maximum principles which are obtained by barrier functions and a coupling argument using a fractional Sobolev trace inequality.

Gods and heroes of Greek myths have been of interest to psychoanalysts, who find them as symbols of human intrapsychic life, evolution, and conflicts. Many of these gods and heroes, like Oedipus, Electra, Eros, and Narcissus, have had their names given to psychological situations, conflicts, and diseases. Freud picked the myth of Narcissus as a symbol of a self-absorbed person whose libido is invested in the ego itself, rather than in other people. The term narcissistic personality disorder, also taken from the myth, describes a self-loving character with grandiose feelings of uniqueness. In this article, I reevaluate the myth of Narcissus and present a different psychoanalytic concept for this story. I view Narcissus as a symbol of a youth who seeks the image of anima or a feminine mental image in interpersonal love relationships, an image that can never be found in the real external world. This misguided quest for an imaginary love object only results in solitude.
SPANISH PEAKS WILDERNESS STUDY AREA, COLORADO.
Budding, Karin E.; Kluender, Steven E.
1984-01-01
A geologic and geochemical investigation and a survey of mines and prospects were conducted to evaluate the mineral-resource potential of the Spanish Peaks Wilderness Study Area, Huerfano and Las Animas Counties, in south-central Colorado. Anomalous gold, silver, copper, lead, and zinc concentrations in rocks and in stream sediments from drainage basins in the vicinity of the old mines and prospects on West Spanish Peak indicate a substantiated mineral-resource potential for base and precious metals in the area surrounding this peak; however, the mineralized veins are sparse, small in size, and generally low in grade. There is a possibility that coal may underlie the study area, but it would be at great depth and it is unlikely that it would have survived the intense igneous activity in the area. There is little likelihood for the occurrence of oil and gas because of the lack of structural traps and the igneous activity.
Kepler's theory of force and his medical sources.
Regier, Jonathan
2014-01-01
Johannes Kepler (1571-1630) makes extensive use of souls and spiritus in his natural philosophy. Recent studies have highlighted their importance in his accounts of celestial generation and astrology. In this study, I would like to address two pressing issues. The first is Kepler's context. The biological side of his natural philosophy is not naively Aristotelian. Instead, he is up to date with contemporary discussions in medically flavored natural philosophy. I will examine his relationship to Melanchthon's anatomical-theological Liber de anima (1552) and to Jean Femel's very popular Physiologia (1567), two Galenic sources with a noticeable impact on how he understands the functions of life. The other issue that will direct my article is force at a distance. Medical ideas deeply inform Kepler's theories of light and solar force (virtus motrix). It will become clear that they are not a hindrance even to the hardcore of his celestial physics. Instead, he makes use of soul and spiritus in order to develop a fully mathematized dynamics.
Advances in studies of disease-navigating webs: Sarcoptes scabiei as a case study
2014-01-01
The discipline of epidemiology is the study of the patterns, causes and effects of health and disease conditions in defined anima populations. It is the key to evidence-based medicine, which is one of the cornerstones of public health. One of the important facets of epidemiology is disease-navigating webs (disease-NW) through which zoonotic and multi-host parasites in general move from one host to another. Epidemiology in this context includes (i) classical epidemiological approaches based on the statistical analysis of disease prevalence and distribution and, more recently, (ii) genetic approaches with approximations of disease-agent population genetics. Both approaches, classical epidemiology and population genetics, are useful for studying disease-NW. However, both have strengths and weaknesses when applied separately, which, unfortunately, is too often current practice. In this paper, we use Sarcoptes scabiei mite epidemiology as a case study to show how important an integrated approach can be in understanding disease-NW and subsequent disease control. PMID:24406101
Data-driven modeling of background and mine-related acidity and metals in river basins
Friedel, Michael J
2013-01-01
A novel application of self-organizing map (SOM) and multivariate statistical techniques is used to model the nonlinear interaction among basin mineral-resources, mining activity, and surface-water quality. First, the SOM is trained using sparse measurements from 228 sample sites in the Animas River Basin, Colorado. The model performance is validated by comparing stochastic predictions of basin-alteration assemblages and mining activity at 104 independent sites. The SOM correctly predicts (>98%) the predominant type of basin hydrothermal alteration and presence (or absence) of mining activity. Second, application of the Davies–Bouldin criteria to k-means clustering of SOM neurons identified ten unique environmental groups. Median statistics of these groups define a nonlinear water-quality response along the spatiotemporal hydrothermal alteration-mining gradient. These results reveal that it is possible to differentiate among the continuum between inputs of background and mine-related acidity and metals, and it provides a basis for future research and empirical model development.
Size-dependent variation in plant form.
Niklas, Karl J; Cobb, Edward D
2017-09-11
The study of organic form has a long and distinguished history going at least as far back as Aristotle's Historia Anima¯lium, wherein he identified five basic biological processes that define the forms of animals (metabolism, temperature regulation, information processing, embryo development, and inheritance). Unfortunately, all of Aristotle's writings about plant forms are lost. We know of them only indirectly from his student Theophrastus's companion books, collectively called Historia Plantarum, wherein plant forms are categorized into annual herbs, herbaceous perennials, shrubs, and trees. The study of plant forms did not truly begin until the romantic poet and naturalist Goethe proposed the concept of a hypothetical 'Plant Archetype', declared "Alles ist Blatt", and first coined the word morphologie, which inspired the French anatomist Cuvier (who established the field of comparative morphology), the English naturalist Darwin (who saw his theory of evolution reinforced by it), and the Scottish mathematician D'Arcy Thompson (who attempted to quantify it).

The "prehistory" of psychology: thoughts on a historiographical illusion.
Vidal, Fernando
2006-01-01
Although it is no longer as current as in the past to identify the "birth" of "scientific psychology" with the establishment of Wilhelm Wundt's laboratory in 1879, Hermann Ebbinghaus's dictum, "Psychology has a long past, but a short history," continues to inspire many authors, and to sustain the belief that there is a "prehistory" of psychology prior to the discipline's institutionalization and professionalization since the last third of the nineteenth century. Such "prehistory" is generally reconstructed by selecting the "psychological ideas" of past thinkers and looking for psychological themes in a variety of intellectual contexts, from medicine to theology. When one, however, considers the origins and uses of the word "psychology" in the sixteenth and seventeenth century, the structure and contents of the scientia de anima in Aristotelian contexts, and how such science was remade in the eighteenth century, it becomes possible to write the early history of psychology as a discipline while avoiding the anachronisms and idiosyncrasies that afflict most reconstructions of its "long" prehistorical past.
Mineralogy from Cores in Prospect Gulch, San Juan County, Colorado
Bove, Dana J.; Johnson, Raymond H.; Yager, Douglas B.
2007-01-01
In the late nineteenth century, San Juan County, Colorado, was the center of a metal mining boom in the San Juan Mountains. Although most mining activity ceased by the 1990s, the effects of historical mining continue to contribute metals to ground water and surface water. Previous research by the U.S. Geological Survey identified ground-water discharge as a significant pathway for the loading of metals to surface water from both acid-mine drainage and acid-rock drainage. In an effort to understand the ground-water flow system in the upper Animas River watershed, Prospect Gulch was selected for further study because of the amount of previous data provided in and around that particular watershed. In support of this ground-water research effort, data was collected from drill core, which included: (1) detailed descriptions of the subsurface geology and hydrothermal alteration patterns, (2) depth of sulfide oxidation, and (3) quantitative mineralogy.
Negative elliptic flow of J/ψ's: A qualitative signature for charm collectivity at RHIC
NASA Astrophysics Data System (ADS)
Krieg, D.; Bleicher, M.
2009-01-01
We discuss one of the most prominent features of the very recent preliminary elliptic flow data of J/ψ-mesons from the PHENIX Collaboration (PHENIX Collaboration (C. Silvestre), arXiv:0806.0475 [nucl-ex]). Even within the rather large error bars of the measured data a negative elliptic flow parameter (v2) for J/ψ in the range of p T = 0.5-2.5 GeV/ c is visible. We argue that this negative elliptic flow at intermediate pT is a clear and qualitative signature for the collectivity of charm quarks produced in nucleus-nucleus reactions at RHIC. Within a parton recombination approach we show that a negative elliptic flow puts a lower limit on the collective transverse velocity of heavy quarks. The numerical value of the transverse flow velocity βT^{} for charm quarks that is necessary to reproduce the data is βT^{}( charm) ˜ 0.55-0.6 c and therefore compatible with the flow of light quarks.

A new species of Heligmonellidae (Trichostrongylina, Heligmosomoidea), Stilestrongylus kaaguyporai n. sp. is described from the small intestine of Euryoryzomys russatus (Rodentia, Cricetidae, Sigmodontinae) from the Argentine Atlantic Forest, in the Misiones province. The new species was found at Campo Anexo Manuel Belgrano, Reserva de Vida Silvestre Urugua-í and Parque Provincial Urugua-í, with a prevalence of 73% in 15 hosts examined. Stilestrongylus includes 24 Neotropical species, all parasitic in rodents, mostly Sigmodontinae. Stilestrongylus kaaguyporai n. sp. can be differentiated from its congeners by the following characters: caudal bursa dissymmetrical with right lobe larger and pattern of type1-4 in both lobes, rays 6 not forming a lateral trident with rays 4 and 5, rays 8 with dissymmetrical pathway, genital cone hypertrophied with a conspicuous hood-like projection and females with a marked dorso-ventral torsion of the posterior end. This report is the second record of a Stilestrongylus species in E. russatus, increasing to nine the number of parasitic species known from this host.

1981-06-01
The Durango Quadrangle (2/sup 0/), Colorado, was evaluated using National Uranium Resource Evaluation criteria to determine environments favorable for uranium deposits. General reconnaissance, geologic and radiometric investigations, was augmented by detailed surface examination and radiometric and geochemical studies in selected areas. Eight areas favorable for uranium deposits were delineated. Favorable geologic environments include roscoelite-type vanadium-uranium deposits in the Placerville and Barlow Creek-Hermosa Creek districts, sandstone uranium deposits along Hermosa Creek, and vein uranium deposits in the Precambrian rocks of the Needle Mountains area and in the Paleozoic rocks of the Tuckerville and Piedra River Canyon areas. The major portions ofmore » the San Juan volcanic field, the San Juan Basin, and the San Luis Basin within the quadrangle were judged unfavorable. Due to lack of information, the roscoelite belt below 1000 ft (300 m), the Eolus Granite below 0.5 mi (0.8 km), and the Lake City caldera are unevaluated. The Precambrian Y melasyenite of Ute Creek and the Animas Formation within the Southern Ute Indian Reservation are unevaluated due to lack of access.« less
Jaguar surveying and monitoring in the United States
Culver, Melanie
2016-06-10
This project established and implemented a noninvasive system for detecting and monitoring jaguars. The study area incorporates most of the mountainous areas north of the United States-Mexico international border and south of Interstate 10, from the Baboquivari Mountains in Arizona to the Animas Mountains in New Mexico. We used two primary methods to detect exact jaguar locations: paired motion-sensor trail cameras, and genetic testing of large carnivore scat collected in the field. We emphasize that this project used entirely noninvasive methods and no jaguars were captured, radiocollared, baited, or harassed in any way. Scat sample collection occurred during the entire field part of the study, but was intensified with the use of a trained scat detection dog following the first jaguar photo detection event (photo detection event was October 2012, scat detection dog began working January 2013). We also collected weather, vegetation, and geographic information system (GIS) data to analyze in conjunction with photo and video data. The results of this study are intended to aid and inform future management and conservation practices for jaguars and ocelots in this region.

The author investigates the relation of Kant, Schopenhauer and Heidegger to Jung's attempts to formulate theory regarding the epistemological conundrum of what can and what cannot be known and what must remain uncertain. Jung's ambivalent use and misuse of Kant's division of the world into phenomenal and noumenal realms is highlighted in discussion of concepts such as the psychoid archetype which he called 'esse in anima' and his use of Schopenhauer's concept of 'will' to justify a transcendence of the psyche/soma divide in a postulation of a 'psychoid' realm. Finally, the author describes Jung's reaction to Heidegger's theories via his assertion that Heidegger's 'pre-given world design' was an alternate formulation of his concept of the archetypes. An underlying theme of the paper is a critique of Jung's foundationalism which perpetuates the myth of an isolated mind. This model of understanding subjectivity is briefly contrasted with Heidegger's 'fundamental ontology' which focuses on a non-Cartesian 'understanding' of the 'presencing of being' in everyday social and historical contexts. © 2011, The Society of Analytical Psychology.

The depth of several thousand feet at which coal may underlie the surface rocks of the study area makes it a resource with little likelihood of development. The potential for oil and gas appears low because of the apparent lack of structural traps and the intense igneous activity in the area.
Neurobiología de la impulsividad y los trastornos de la conducta alimentaria*
Orozco-Cabal, Luis Felipe; Herin, David
2009-01-01
Resumen Introducción La impulsividad es un rasgo de personalidad multidimensional relacionado con el control del comportamiento y las emociones. Está presente de manera diversa en los trastornos de la conducta alimentaria, particularmente, en la bulimia nerviosa (BN). Aunque la relación entre la impulsividad y BN ha sido objeto de numerosas investigaciones, en la actualidad se desconocen los sustratos neurobiológicos de esta relación. Objetivos Discutir críticamente la evidencia que sugiere que las alteraciones en los sistemas neuronales relacio-nados con las funciones ejecutivas, con la formación de preferencias y con la regulación de los estados emocionales sirven como base para el rasgo de personalidad impulsiva, así como su estado en subgrupos de pacientes con BN. Métodos Búsqueda selectiva de la literatura relevante. Resultados y conclusiones Esta discusión ilustra la complejidad de la relación entre la impulsividad y BN, donde la impulsividad actúa como un factor de vulnerabilidad que puede sensibilizar al sujeto con BN a estados emocionales negativos, durante los cuales modifica el impacto de estímulos internos y externos sobre el comportamiento y su regulación, favoreciendo así patrones de comportamiento maladaptativos e inflexibles.

Population growth and the potential development of subsurface mineral resources have increased the need for information on the availability and quality of ground water on the Southern Ute Indian Reservation. The U.S. Geological Survey, in cooperation with the Southern Ute Tribal Council, the Four Corners Regional Planning Commission, and the U.S. Bureau of Indian Affairs, conducted a study during 1974-76 to assess the ground-water resources of the reservation. Water occurs in aquifers in the Dakota Sandstone, Mancos Shale, Mesaverde Group, Lewis Shale, Pictured Cliffs Sandstone, Fruitland Formation, Kirtland Shale, Animas and San Jose Formations, and terrace and flood-plain deposits. Well yields from sandstone and shale aquifers are small, generally in the range from 1 to 10 gallons per minute with maximum reported yields of 75 gallons per minute. Well yields from terrace deposits generally range from 5 to 10 gallons per minute with maximum yields of 50 gallons per minute. Well yields from flood-plain deposits are as much as 25 gallons per minute but average 10 gallons per minute. Water quality in aquifers depends in part on rock type. Water from sandstone, terrace, and flood-plain aquifers is predominantly a calcium bicarbonate type, whereas water from shale aquifers is predominantly a sodium bicarbonate type. Water from rocks containing interbeds of coal or carbonaceous shales may be either a calcium or sodium sulfate type. Dissolved-solids concentrations of ground water ranged from 115 to 7,130 milligrams per liter. Water from bedrock aquifers is the most mineralized, while water from terrace and flood-plain aquifers is the least mineralized. In many water samples collected from bedrock, terrace, and flood-plain aquifers, the concentrations of arsenic, chloride, dissolved solids, fluoride, iron, manganese, nitrate, selenium, and sulfate exceeded U.S. Public Health Service (1962) recommended limits for drinking water.

This study explored choice factors in four specialties in Mexico. Mixed methods design. Qualitative phase: four focus groups with first-year residents, to obtain information of how specialty choice was done. With this information a web-based cross-sectional questionnaire was applied to residents registered in the 1st year of Postgraduate Studies Division, UNAM. 32 residents participated in qualitative phase and for the quantitative phase, the survey was answered by 35 surgical, 28 gynecology, 61 internal medicine and 62 pediatric residents. The specialty choice decision was done during the last years of the medical career. The majority of the resident choice was a subspecialty after the general residency. The type of patient was more crucial to choose pediatrics while a good academic program was for internal medicine. Negative models and bullying were decisive to rule out surgery as well as a not well-known hospital was to rule out pediatrics. The specialty choice is done during undergraduate training, with the intention of doing a subspecialty. Demographic and personality traits were identified. Copyright: © 2017 SecretarÍa de Salud

We extend the use of a novel tracing technique to quantify the bioavailability of zinc (Zn) associated with natural particles using snails enriched with a less common Zn stable isotope. Lymnaea stagnalis is a model species that has relatively fast Zn uptake rates from the dissolved phase, enabling their rapid enrichment in 67Zn during the initial phase of labeling. Isotopically enriched snails were subsequently exposed to algae mixed with increasing amounts of metal-rich particles collected from two acid mine drainage impacted rivers. Zinc bioavailability from the natural particles was inferred from calculations of 66Zn assimilation into the snail’s soft tissues. Zinc assimilation efficiency (AE) varied from 28% for the Animas River particles to 45% for the Snake River particles, indicating that particle-bound, or sorbed Zn, was bioavailable from acid mine drainage wastes. The relative binding strength of Zn sorption to the natural particles was inversely related to Zn bioavailability; a finding that would not have been possible without using the reverse labeling approach. Differences in the chemical composition of the particles suggest that their geochemical properties may influence the extent of Zn bioavailability.

In the late nineteenth century, San Juan County, Colorado, was the center of a metal mining boom in the San Juan Mountains. Although most mining activity ceased by the 1990s, the effects of historical mining continue to contribute metals to ground water and surface water. Previous research by the U.S. Geological Survey identified ground-water discharge as a significant pathway for the loading of metals to surface water from both acid-mine drainage and acid-rock drainage. In an effort to understand the ground-water flow system in the upper Animas River watershed, Prospect Gulch was selected for further study because of the amount of previous data provided in and around that particular watershed. In support of this ground-water research effort, wells and piezometers were installed to allow for coring during installation, subsurface hydrologic testing, and the monitoring of ground-water hydraulic heads and geochemistry. This report summarizes the data that were collected during and after the installation of these wells and piezometers and includes (1) subsurface completion details, (2) locations and elevations, (3) geologic logs and elemental data, (4) slug test data for the estimation of subsurface hydraulic conductives, and (5) hydraulic head data.

Recovery of dynamic balance, involving adjustment of the center of gravity, is essential for safe discharge on foot after ambulatory anesthesia. The purpose of this study was to assess the recovery of dynamic balance after general anesthesia with sevoflurane, using two computerized dynamic posturographies. Nine hospitalized patients undergoing oral surgery of less than 2 h duration under general anesthesia (air-oxygensevoflurane) were studied. A dynamic balance test, assessing the ability of postural control against unpredictable perturbation stimuli (Stability System; Biodex Medical), a walking analysis test using sheets with foot pressure sensors (Walk Way-MG1000; Anima), and two simple psychomotor function tests were performed before anesthesia (baseline), and 150 and 210 min after the emergence from anesthesia. Only the double-stance phase in the walking analysis test showed a significant difference between baseline and results at 150 min. None of the other variables showed any differences among results at baseline and at 150 and 210 min. The recovery times for dynamic balance and psychomotor function seem to be within 150 min after emergence from general anesthesia with sevoflurane in patients undergoing oral surgery of less than 2-h duration.

A U.S. Geological Survey Abandoned Mine Lands Initiative will develop a strategy for gathering and communicating the scientific information needed to formulate effective and cost-efficient remediation of abandoned mine lands. A watershed approach will identify, characterize, and remediate contaminated sites that have the most profound effect on water and ecosystem quality within a watershed. The Initiative will be conducted during 1997 through 2001 in two pilot watersheds, the Upper Animas River watershed in Colorado and the Boulder River watershed in Montana. Initiative efforts are being coordinated with the U.S. Forest Service, Bureau of Land Management, National Park Service, and other stakeholders which are using the resulting scientific information to design and implement remediation activities. The Initiative has the following eight objective-oriented components: estimate background (pre-mining) conditions; define baseline (current) conditions; identify target sites (major contaminant sources); characterize target sites and processes affecting contaminant dispersal; characterize ecosystem health and controlling processes at target sites; develop remediation goals and monitoring network; provide an integrated, quality-assured and accessible data network; and document lessons learned for future applications of the watershed approach.
Soul in the world: symbolic culture as the medium for psyche.
Colman, Warren
2017-02-01
Whilst the loss of a sense of living connection with the material world is mainly associated with the scientific revolution in seventeenth century Europe, it can be traced back to Plato's introduction of a hierarchy between soul and body. Jung's attempted solution to this - esse in anima - is ingenious but maintains the Cartesian split by which the aliveness of the world is reduced to a projection of psychic forces (the archetypes). An alternative approach is proposed, rooted in the Aristotelean emphasis on practical activity that sees the soul as a function of our way of being in the world. Human cognition is extended and distributed by our social and material engagement with the world, especially via collective representations whose symbolic character is constitutive of the reality of the world in which we live. Despite the dominance of 'scientific Cartesian' representations in the modern Western world, there remain numerous instances of participation mystique that cannot be captured by the Cartesian notion of projection. These indicate an opening to ways of being in the world that may lead us out of the impasse of the Cartesian matrix. © 2017, The Society of Analytical Psychology.

The study area comprises the Humboldt River Basin and adjacent areas, with emphasis on mining areas relatively close to the Humboldt River. The basin comprises about 16,840 mi2 or 10,800,000 acres. The mineral resources of the Humboldt Basin have been investigated by many scientists over the past 100 years, but only recently has our knowledge of regional geology and mine geology been applied to the understanding and evaluation of mining effects on water and environmental quality. The investigations reported here apply some of the techniques and perspectives developed in the Abandoned Mine Lands Initiative (AMLI) of the U.S. Geological Survey (USGS), a program of integrated geological-hydrological-biological-chemical studies underway in the Upper Animas River watershed in Colorado and the Boulder River watershed in, Montana. The goal of my studies of sites and districts is to determine the character of mining-related contamination that is actively or potentially a threat to water quality and to estimate the potential for natural attenuation of that contamination. These geology-based studies and recommendations differ in matters of emphasis and data collection from the biology-based assessments that are the cornerstone of environmental regulations.

Resumo A incidência de hipertensão arterial sistêmica está aumentando mundialmente. Sua prevenção baseia-se na identificação dos hipertensos. Atualmente, biomarcadores são utilizados com fins de diagnosticar, estratificar e prognosticar doenças. Neste estudo, objetivou-se revisar artigos dos últimos cinco anos relacionados a biomarcadores nas doenças cardiovasculares. Pesquisaram-se dados de PubMed, SciELO, Science Direct e MEDLINE, mediante as palavras-chave: hipertensão arterial, biomarcadores cardiovasculares, óxido nítrico, função endotelial e dimetilarginina assimétrica. Os estudos levantados mostram que as doenças cardiovasculares possuem uma etiologia complexa. Neste artigo, evidenciaram-se interações entre o óxido nítrico e a dimetilarginina assimétrica na regulação, no metabolismo e na determinação dos níveis intracelulares, e reviram-se outros biomarcadores relacionados à hipertensão. Alguns estudos indicam os biomarcadores como uma ferramenta útil na predição de eventos cardíacos, e outros reportam que eles contribuem pouco para a avaliação. A seleção e combinação desses pode ser uma alternativa para validar o uso dos biomarcadores devido à pouca especificidade existente para diagnosticar a hipertensão. PMID:29930594

tests with wild flies. As colonization progressed, life expectancy and fecundity rates increased in the 3 rearing systems. There was no significant difference in standard quality control parameters among the 3 rearing systems. Wild males always achieved more matings than any of the mass reared males. Mating competitiveness of males from the IS, although surprisingly not from the SS, was significantly greater than that of males from the MS. Our results indicate that these slight changes in the adult holding conditions can significantly reduce the harmful effects of mass rearing on the mating performance of sterile flies.

To identify the incidence of delirium, compare the demographic and clinical characteristics of patients with and without delirium, and verify factors related to delirium in critical care patients. Prospective cohort with a sample made up of patients hospitalized in the Intensive Care Unit (ICU) of a university hospital. Demographic, clinical variables and evaluation with the Confusion Assessment Method for Intensive Care Unit to identify delirium were processed to the univariate analysis and logistic regression to identify factors related to the occurrence of delirium. Of the total 149 patients in the sample, 69 (46.3%) presented delirium during ICU stay, whose mean age, severity of illness and length of ICU stay were statistically higher. The factors related to delirium were: age, midazolam, morphine and propofol. Results showed high incidence of ICU delirium associated with older age, use of sedatives and analgesics, emphasizing the need for relevant nursing care to prevent and identify early, patients presenting these characteristics.

We devised a novel tracing approach that involves enriching test organisms with a stable metal isotope of low natural abundance prior to characterizing metal bioavailability from natural inorganic particles. In addition to circumventing uncertainties associated with labeling natural particles and distinguishing background metals, the proposed "reverse labeling" technique overcomes many drawbacks inherent to using radioisotope tracers. Specifically, we chronically exposed freshwater snails (Lymnaea stagnalis) to synthetic water spiked with Cu that was 99.4% 65Cu to increase the relative abundance of 65Cu in the snail’s tissues from 32% to >80%. The isotopically enriched snails were then exposed to benthic algae mixed with Cu-bearing Fe–Al particles collected from the Animas River (Colorado), an acid mine drainage impacted river. We used 63Cu to trace Cu uptake from the natural particles and inferred their bioavailability from calculation of Cu assimilation into tissues. Cu assimilation from these particles was 44%, indicating that 44% of the particulate Cu was absorbed by the invertebrate. This demonstrates that inorganic particulate Cu can be bioavailable. The reverse labeling approach shows great potential in various scientific areas such as environmental contamination and nutrition for addressing questions involving uptake of an element that naturally has multiple isotopes.

Area 61 is located on the Colorado-New Mexico boundary in Huerfano and Las Animas Counties, Colorado, and Colfax County, New Mexico, and includes the Raton Mesa coal region. The 5 ,900-square-mile area is an asymmetrical structural trough bounded by the Rocky Mountains on the west and the Great Plains on the east. The area is drained by the Huerfano, Apishapa, Purgatoire, and Canadian Rivers (and their tributaries), all tributary to the Arkansas River. The principal coal-bearing formations are the Vermejo Formation of Late Cretaceous age and the Raton Formation of Late Cretaceous and Paleocene age. Much of the coal in the area is of coking quality, important to the metallurgical industry. Topographic relief in the area is greater than 8,700 feet, and this influences the climate which in turn affects the runoff pattern of area streams. Summer thunderstorms often result in flash floods. Virtually all geologic units in the region yield water. Depth to ground water ranges from land surface to 400 feet. Surface and ground water in the area contain mostly bicarbonate and sulfate ions; locally in the ground water, chloride ions predominate. Potential hydrologic problems associated with surface coal mining in the area are water-quality degradation, water-table decline, and increased erosion and sedimentation.

This study aimed to examine gender differences in 4 body-sway factors of the center of foot pressure (CFP) during a static upright posture and the influence of alcohol intake on them. Four body-sway factors were interpreted in previous studies using factor analysis (the principal factor method and oblique solution by promax-rotation) on 220 healthy young males and females as follows; unit time sway, front-back sway, left-right sway and high frequency band power. The CFP measurement for 1 min was carried out twice with 1 min rest. The measurements of blood pressure, heart rate, whole body reaction time, standing on one leg with eyes closed, and CFP were carried out before and after the alcohol intake using 11 healthy young males and females. The measurement device used was an Anima's stabilometer G5500. The data sampling frequency was 20 Hz. Reliability of 4 body-sway factors was very high. Significant gender differences were found in the left-right sway and the high frequency band power factors, but the influence on body-sway is, as a whole, can be disregarded. These four sway factors can determine the influence of alcohol intake as efficient as 32 sway parameters.

In bionic methodology rather than in design methodology more familiar with, summarizing the psychological researches of emotion, we propose the biologic mechanism of emotion, emotion selection role in creature evolution and a anima framework including emotion similar to the classical control structure; and consulting Prospect Theory, build an Emotion Characteristic Functions(ECF) that computer emotion; two more emotion theories are added to them that higher emotion is preferred and middle emotion makes brain run more efficiently, emotional behavior mechanism comes into being. A simulation of proposed mechanism are designed and carried out on Alife Swarm software platform. In this simulation, a virtual grassland ecosystem is achieved where there are two kinds of artificial animals: herbivore and preyer. These artificial animals execute four types of behavior: wandering, escaping, finding food, finding sex partner in their lives. According the theories of animal ethnology, escaping from preyer is prior to other behaviors for its existence, finding food is secondly important behavior, rating is third one and wandering is last behavior. In keeping this behavior order, based on our behavior characteristic function theory, the specific functions of emotion computing are built of artificial autonomous animals. The result of simulation confirms the behavior selection mechanism.
Constraints on the sedimentation history of San Francisco Bay from 14C and 10Be

Industrialization and urbanization around San Francisco Bay as well as mining and agriculture in the watersheds of the Sacramento and San Joaquin rivers have profoundly modified sedimentation patterns throughout the estuary. We provide some constraints on the onset of these erosional disturbances with 10Be data for three sediment cores: two from Richardson Bay, a small embayment near the mouth of San Francisco Bay, and one from San Pablo Bay, mid-way between the river delta and the mouth. Comparison of pre-disturbance sediment accumulation determined from three 14C-dated mollusk shells in one Richardson Bay core with more recent conditions determined from the distribution of 210Pb and 234Th [Fuller, C.C., van Geen, A., Baskaran, M, Anima, R.J., 1999. Sediment chronology in San Francisco Bay, California, defined by 210Pb, 234Th, 239,240Pu.] shows that the accumulation rate increased by an order of magnitude at this particular site. All three cores from San Francisco Bay show subsurface maxima in 10Be concentrations ranging in magnitude from 170 to 520 x 106 atoms/g. The transient nature of the increased 10Be input suggests that deforestation and agricultural develop- ment caused basin-wide erosion of surface soils enriched in 10Be. probably before the turn of the century.
Methodology and Implications of Maximum Paleodischarge Estimates for
Channels, M.; Pruess, J.; Wohl, E.E.; Jarrett, R.D.

Historical and geologic records may be used to enhance magnitude estimates for extreme floods along mountain channels, as demonstrated in this study from the San Juan Mountains of Colorado. Historical photographs and local newspaper accounts from the October 1911 flood indicate the likely extent of flooding and damage. A checklist designed to organize and numerically score evidence of flooding was used in 15 field reconnaissance surveys in the upper Animas River valley of southwestern Colorado. Step-backwater flow modeling estimated the discharges necessary to create longitudinal flood bars observed at 6 additional field sites. According to these analyses, maximum unit discharge peaks at approximately 1.3 m3 s~' km"2 around 2200 m elevation, with decreased unit discharges at both higher and lower elevations. These results (1) are consistent with Jarrett's (1987, 1990, 1993) maximum 2300-m elevation limit for flash-flooding in the Colorado Rocky Mountains, and (2) suggest that current Probable Maximum Flood (PMF) estimates based on a 24-h rainfall of 30 cm at elevations above 2700 m are unrealistically large. The methodology used for this study should be readily applicable to other mountain regions where systematic streamflow records are of short duration or nonexistent. ?? 1998 Regents of the University of Colorado.

Excavation control to the 15 pCi/g radium-226 (Ra-226) standard at certain areas along the Animas River on the Durango Site would require extensive engineering and construction support. Elevated Ra-226 concentrations have been encountered immediately adjacent to the river at depths in excess of 7 feet below the present river stage. Decontamination to such depths to ensure compliance with the EPA standards will, in our opinion, become unreasonable. This work does not appear to be in keeping with the intent of the standards. Because the principal reason for radium removal is reduction of radon daughter concentrations (RDC) in homes to bemore » built onsite, and because radon produced at depth will be attenuated in clean fill cover before entering such homes, it is appropriate to calculate the depth of excavation needed under a home to reduce RDC to acceptable levels. Potential impact was assessed through radon emanation estimation, using the RAECOM computer model. Elevated Ra-226 concentrations were encountered during final radium excavation of the flood plain below the large tailings pile, adjacent to the slag area. Data from 7 test pits excavated across the area were analyzed to provide an estimate of the Ra-226 concentration profile. Results are given in this report.« less
Electrical resistivity surveys in Prospect Gulch, San Juan County, Colorado
McDougal, Robert R.
2006-01-01
Prospect Gulch is a major source of naturally occurring and mining related metals to Cement Creek, a tributary of the upper Animas River in southwestern Colorado. Efforts to improve water quality in the watershed have focused on Prospect Gulch because many of its abandoned mines and are located on federal lands. Information on sources and pathways of metals, and related ground-water flow, will be useful to help prioritize and develop remediation strategies. It has been shown that the occurrence of sulfate, aluminum, iron, zinc and other metals associated with historical mining and the natural weathering of pyritic rock is substantial. In this study, direct current resistivity surveys were conducted to determine the subsurface resistivity distribution and to identify faults and fractures that may act as ground-water conduits or barriers to flow. Five lines of resistivity data were collected in the vicinity of Prospect Gulch, and cross-section profiles were constructed from the field data using a two-dimensional inversion algorithm. The conductive anomalies in the profiles are most likely caused by wet or saturated rocks and sediments, clay rich deposits, or high TDS ground water. Resistive anomalies are likely bedrock, dry surficial and sub-surface deposits, or deposits of ferricrete.

In San Juan County, Colo., the effects of historical mining continue to contribute metals to ground water and surface water. Previous research by the U.S. Geological Survey identified ground-water discharge as a significant pathway for the loading of metals to surface water in the upper Animas River watershed from both acid-mine drainage and acid-rock drainage. In support of this ground-water research effort, Prospect Gulch was selected for further study and the geochemistry of surface and ground water in the area was analyzed as part of four sampling plans: (1) ten streamflow and geochemistry measurements at five stream locations (four locations along Cement Creek plus the mouth of Prospect Gulch from July 2004 through August 2005), (2) detailed stream tracer dilution studies in Prospect Gulch and in Cement Creek from Gladstone to Georgia Gulch in early October 2004, (3) geochemistry of ground water through sampling of monitoring wells, piezometers, mine shafts, and springs, and (4) samples for noble gases and tritium/helium for recharge temperatures (recharge elevation) and ground-water age dating. This report summarizes all of the surface and ground-water data that was collected and includes: (1) all sample collection locations, (2) streamflow and geochemistry, (3) ground-water geochemistry, and (4) noble gas and tritium/helium data.
On August 5, 2015, a large acidic mine pool trapped behind a collapsed mine structure and rock debris in the Gold King Mine (GKM) was accidently breached releasing approximately 11.3 million liters (3 million gallons) of low pH (~3) metal contaminated mine drainage into a small t...

strongly affected by natural acidity from pyrite weathering. Metal content in the water column is a composite of multiple sources affected by hydrologic, geologic, climatic, and anthropogenic conditions. Identifying sources of metals from various drainage areas was determined using a tracer injection approach and synoptic sampling during low flow conditions on September 29, 1999 to determine loads. The tracer data was interpreted in conjunction with detailed geologic mapping, topographic profiling, geochemical characterization, and the occurrence and distribution of trace metals to identify sources of ground-water inflows. For this highly mineralized sub-basin, we demonstrate that SO4, Al, and Fe load contributions from drainage areas that have experienced historical mining?although substantial?are relatively insignificant in comparison with SO4, Al, and Fe loads from areas experiencing natural weathering of highlyaltered, pyritic rocks. Regional weathering of acid-sulfate mineral assemblages produces moderately low pH waters elevated in SO4, Al, and Fe; but generally lacking in Cu, Cd, Ni, and Pb. Samples impacted by mining are also characterized by low pH and large concentrations of SO4, Al, and Fe; but contained elevated dissolved metals from ore-bearing vein minerals such as Cu, Zn, Cd, Ni, and Pb. Occurrences of dissolved trace metals were helpful in identifying ground-water sources and flow paths. For example, cadmium was greatest in inflows associated with drainage from inactive mine sites and absent in inflows that were unaffected by past mining activities and thus served as an important indicator of mining contamination for this environmental setting. The most heavily mine-impacted reach (PG153 to PG800), contributed 8% of the discharge, and 11%, 9%, and 12% of the total SO4, Al, and Fe loads in Prospect Gulch. The same reach yielded 59% and 37% of the total Cu and Zn loads for the subbasin. In contrast, the naturally acidic inflows from the Red Chemotroph iron spring yielded 39% of the discharge and 54%, 73%, and 87% of the SO4, Al, and Fe loads; but only 4% of the total Cu and 30% of the total Zn loads in Prospect Gulch. Base flow from the Prospect Gulch sub-basin contributes about 4.8 percent of the total discharge at the mouth of Cement Creek; compared with sampled instream loads of 1.8%, 8.8%, 15.9%, 28%, and 8.6% for SO4, Al, Fe, Cu and Zn, respectively. Water-shed scale remediation efforts targeted at reducing loads of SO4, Al, and Fe at inactive mine sites are likely to fail because the major sources of these constituents in Prospect Gulch are predominantly discharged from natural sources. Remediation goals aimed at reducing acidity and loads of Cu and other base metals, may succeed, however, because changes in pH and loads are disproportionately greater than increases in discharge over the same reach, and a substantial fraction of the metal loading is from mining-impacted reaches. Whether remediation of abandoned mines in Prospect Gulch can be successful depends on how goals are defined?that is, whether the objective is to reduce loads of SO4, Al, and Fe; or whether loads of Cu and other base metals and pH are targeted.

Background In 2004, Uslan and colleagues determined that insulin pumps (IPs) on the market were largely inaccessible to blind and visually impaired persons. The objective of this study is to determine if accessibility status changed in the ensuing 4 years. Methods Five IPs on the market in 2008 were acquired and analyzed for key accessibility traits such as speech and other audio output, tactual nature of control buttons, and the quality of visual displays. It was also determined whether or not a blind or visually impaired person could independently complete tasks such as programming the IP for insulin delivery, replacing batteries, and reading manuals and other documentation. Results It was found that IPs have not improved in accessibility since 2004. None have speech output, and with the exception of the Animas IR 2020, no significantly improved visual display characteristics were found. Documentation is still not completely accessible. Conclusion Insulin pumps are relatively complex devices, with serious health consequences resulting from improper use. For IPs to be used safely and independently by blind and visually impaired patients, they must include voice output to communicate all the information presented on their display screens. Enhancing display contrast and the size of the displayed information would also improve accessibility for visually impaired users. The IPs must also come with accessible user documentation in alternate formats. PMID:20144301

Utilization of Expert Knowledge in a Multi-Objective Hydrologic Model Automatic Calibration Process

Spatially distributed continuous simulation hydrologic models have a large number of parameters for potential adjustment during the calibration process. Traditional manual calibration approaches of such a modeling system is extremely laborious, which has historically motivated the use of automatic calibration procedures. With a large selection of model parameters, achieving high degrees of objective space fitness - measured with typical metrics such as Nash-Sutcliffe, Kling-Gupta, RMSE, etc. - can easily be achieved using a range of evolutionary algorithms. A concern with this approach is the high degree of compensatory calibration, with many similarly performing solutions, and yet grossly varying parameter set solutions. To help alleviate this concern, and mimic manual calibration processes, expert knowledge is proposed for inclusion within the multi-objective functions, which evaluates the parameter decision space. As a result, Pareto solutions are identified with high degrees of fitness, but also create parameter sets that maintain and utilize available expert knowledge resulting in more realistic and consistent solutions. This process was tested using the joint SNOW-17 and Sacramento Soil Moisture Accounting method (SAC-SMA) within the Animas River basin in Colorado. Three different elevation zones, each with a range of parameters, resulted in over 35 model parameters simultaneously calibrated. As a result, high degrees of fitness were achieved, in addition to the development of more realistic and consistent parameter sets such as those typically achieved during manual calibration procedures.
Lessons learned from the U.S. Geological Survey abandoned mine lands initiative: 1997-2002
Kimball, Briant A.; Church, Stan E.; Besser, John M.

Growth of the United States has been facilitated, in part, by hard-rock mining in the Rocky Mountains. Abandoned and inactive mines cause many significant environmental concerns in hundreds of watersheds. Those who have responsibility to address these environmental concerns must have a basic level of scientific information about mining and mine wastes in a watershed prior to initiating remediation activities. To demonstrate what information is needed and how to obtain that information, the U.S. Geological Survey implemented the Abandoned Mine Lands (AML) Initiative from 1997 to 2002 with demonstration studies in the Boulder River watershed in Montana and the Animas River watershed in Colorado. The AML Initiative included collection and analysis of geologic, hydrologic, geochemical, geophysical, and biological data. The synergy of this interdisciplinary analysis produced a perspective of the environmental concerns that could not have come from a single discipline. Two examples of these perspectives include (1) the combination of hydrological tracer techniques, structural geology, and geophysics help to understand the spatial distribution of loading to the streams in a way that cannot be evaluated by monitoring at a catchment outlet, and (2) the combination of toxicology and hydrology combine to illustrate that seasonal variability of toxicity conditions occurs. Lessons have been learned by listening to and collaborating with land-management agencies to understand their needs and by applying interdisciplinary methods to answer their questions.

This geologic map covers four 7.5-minute quadrangles-The Wall, NM-CO (New Mexico-Colorado), Vermejo Park, NM-CO, Ash Mountain, NM, and Van Bremmer Park, NM. The study area straddles the boundary between the eastern flank of the Sangre de Cristo Mountains and the western margin of the Raton Basin, with about two-thirds of the map area in the basin. The Raton Basin is a foreland basin that formed immediately eastward of the Sangre de Cristo Mountains during their initial uplift, in the Late Cretaceous through early Eocene Laramide orogeny. Subsequently, these mountains have been extensively modified during formation of the Rio Grande rift, from late Oligocene to present. The map area is within that part of the Sangre de Cristo Mountains that is called the Culebra Range. Additionally, the map covers small parts of the Devil's Park graben and the Valle Vidal half-graben, in the northwestern and southwestern parts of the map area, respectively. These two grabens are small intermontaine basins, that are satellitic to the main local basin of the Rio Grande rift, the San Luis Basin, that are an outlying, early- formed part of the rift, and that separate the Culebra Range from the Taos Range, to the southwest.

The results of many studies describing sour cherry polyphenols and their positive effects on human health have been reported. However, there are no detailed studies concerning the physical quality of fresh fruits of sour and duke cherry. Several physical, chemical and colour fruit-characteristics of 10 sour and duke cherry cultivars cultivated for industrial use in south-west Europe were investigated during a 3-year (2008-2010) period. Some of the cultivars showed distinctive and interesting agronomical characters, such as low susceptibility to fruit cracking and high soluble solids and total polyphenol levels. This was the case with the duke cherry cultivar Guindo Garrafal Negro. Its fruits were quite sweet (18.49°Brix), resistant to cracking (6.34%) and rich in polyphenols (17.16 g gallic acid kg(-1) dry weight). Other relevant cherry cultivars were Guindo Tomatillo and Seixas, which had large and fleshy fruits (4.71 and 3.69 cm(3), respectively) and Guindo Silvestre, for which the lowest fruit cracking values (3.12%) were recorded. Sour and duke cherries are rich in healthy compounds such as polyphenols. Studies including the physical, chemical and colour properties of sour and duke cherry fruits are very interesting to engineers in the design of equipment for harvesting and post-harvest technology. © 2013 Society of Chemical Industry.

Qualitative-quantitative structure of plant pigments in wild plants Malva silvestrs L. and Malva moschata L. (Malvaceae), which were collected in 20 locations in Sarajevo area and surroundings, was tested during spring and summer in 2003. Acetone extracts of both categories were made and rising paper-chromatography done for the purpose of qualitative analysis. Quantitative analysis was done by spectrophotometry. Chlorophyll a, chlorophyll b and xanthophylls presence was confirmed by separation of pigments from acetone extract of these plant species. Spectrophotometric analysis of acetone extracts showed these results (given in mg/L): chlorophyll a 2,386, chlorophyll b 0,332 and carrotenoides 1,037. Data given in mg/g dry substance are: chlorophyll a 1,193x10(-2), chlorophyll b 1,66x10(-3), and carrotenoides 5,185x10(-3). Pigments structure (in mg/L) in species Malva moschata is 1,6 for chlorophyll; 1,419 for chlorophyll b; and 0,364 for carrotenoides. Data given in mg/g are: chlorophyll a 8x10(-3), chlorophyll b 7,09x10(-3), and carrotenoides 1,82x10(-3). Considering that species Malva moschata L. grows on ecologically clear soils as opposed to well-known medicinal species Malva sylvestris L., and considering the production of phytomass, phytochemical structure and pharmacological influence it can be considered very medical and be given advantage over this wider spread category.

Land planarians are an interesting group of free-living flatworms that can be useful as bioindicators because of their high sensitivity to environmental changes and low dispersal capacity. In this study, we describe and compare assemblages of land planarians from areas with different conservation degrees of the Interior Atlantic Forest (Misiones, Argentina), and assess factors that could be related to their abundance and richness. Eight sites were tracked in search of land planarians in Reserva de Vida Silvestre Urugua-í (RVSU) and Campo Anexo Manuel Belgrano (CAMB). Diurnal and nocturnal surveys were performed in each site along nine sampling campaigns. We collected 237 individuals belonging to 18 species of the subfamily Geoplaninae. All sites were dominated by Geoplana sp. 1 and Pasipha hauseri. The richness estimators showed that there would be more species in RVSU than in CAMB. The abundance and richness of land planarians was high during the night and after rainfalls, suggesting an increased activity of flatworms under such conditions. The abundance and richness of land planarians were also related to the conservation condition of the sites. Disturbed sites showed less abundance and richness, and were segregated from non-disturbed ones by nmMDS analysis. Beta diversity between sites was higher than expected, indicating that the species turnover between sites contributed more to the total richness (gamma diversity) than the alpha diversity.

Sendo a Astronomia uma das cièncias mais antigas da humanidade, e considerando sua importáncia histórica e cultural, é de extrema releváncia que tópicos relacionados a ela sejam tratados nas escolas. Embora os Parámetros Curriculares Nacionais do Ensino Médio (PCN-EM) e as Orientaçiacute;es Complementares aos Parámetros (PCN+) apontem a importáncia de uma abordagem significativa de conceitos relacionados à Astronomia nas aulas de Física, muitos estudantes terminam o Ensino Médio (EM) sem compreender a razão de certos acontecimentos de origem celeste, ainda que estes façam parte de seu cotidiano e sejam alvos da curiosidade natural dos jovens. Da observação dessa curiosidade em alunos de uma escola pública paulista, na cidade de Suzano, surgiu o interesse em investigar os conhecimentos básicos em Astronomia dos alunos do Ensino Médio desta escola, constituindo-se este como principal objetivo desta pesquisa. Para tanto foi elaborado um questionário de múltipla escolha aplicado inicialmente a 34 alunos do primeiro ano e, posteriormente, a mais 310, distribuídos entre as très séries do Ensino Médio dos períodos matutino e noturno. Dessa forma, observou-se que 73,9% dos estudantes identificaram o Sol como sendo uma estrela, 67,1% mostraram compreender a sucessão entre dia e noite e 52,3% relacionaram o Big Bang à origem do Universo. Em contrapartida, apenas 34,5% relacionaram as estaçíes do ano à inclinação do eixo de rotação da Terra, 21,3% indicaram a influència gravitacional simultánea da Lua e do Sol como responsável pelo fenòmeno das marés, 24,5% indicaram corretamente quais são os objetos celestes mais próximos da Terra, 36,1% identificaram ano-luz como uma medida de distáncia e 34,2% reconheceram as estrelas cadentes como meteoros, evidenciando-se assim o pequeno discernimento dos estudantes quanto aos fenòmenos e termos astronòmicos do cotidiano.

This study aimed to validate the definition and define the characteristics and related factors of unemployment disorder, a proposed nursing diagnosis. Using Fehring's diagnostic content validity model, Spanish experts were asked to assess the adequacy of the label, defining the characteristics and other related factors. The content validity index was 0.8690. A total of 16 defining characteristics reached major criteria (>0.80). The present study supports the proposed development of a nursing diagnosis for the human response to unemployment. The results suggest that the inclusion of the "unemployment disorder" diagnostic NANDA-I taxonomy would allow nursing professionals to identify the disorder and its causes and manifestations, and therefore provide the information needed for planning more relevant interventions and results.

Ghrelin is an endogenous regulator of energy homeostasis synthesized by the stomach to stimulate appetite and positive energy balance. Similarly, the endocannabinoid system is part of our internal machinery controlling food intake and energy expenditure. Both peripheral and central mechanisms regulate CB1-mediated control of food intake and a functional relationship between hypothalamic ghrelin and cannabinoid CB1 receptor has been proposed. First of all, we investigated brain ghrelin actions on food intake in rats with different metabolic status (negative or equilibrate energy balance). Secondly, we tested a sub-anxiogenic ultra-low dose of the CB1 antagonist SR141716A (Rimonabant) and the peripheral-acting CB1 antagonist LH-21 on ghrelin orexigenic actions. We found that: 1) central administration of ghrelin promotes food intake in free feeding animals but not in 24 h food-deprived or chronically food-restricted animals; 2) an ultra-low dose of SR141716A (a subthreshold dose 75 folds lower than the EC50 for induction of anxiety) completely counteracts the orexigenic actions of central ghrelin in free feeding animals; 3) the peripheral-restricted CB1 antagonist LH-21 blocks ghrelin-induced hyperphagia in free feeding animals. Our study highlights the importance of the animaĺs metabolic status for the effectiveness of ghrelin in promoting feeding, and suggests that the peripheral endocannabinoid system may interact with ghrelińs signal in the control of food intake under equilibrate energy balance conditions.

Analyses indicate that water quality in the San Juan River drainage basin upstream from Shiprock, New Mexico, is quite variable from station to station. Analyses are based on water quality data from the U.S. Geological Survey WATSTORE files and the New Mexico Environmental Improvement Division 's files. In the northeastern part of the basin, most streams are calcium-bicarbonate waters. In the northwestern and southern part of the basin, the streams are calcium-sulfate and sodium-sulfate waters. Geology, climate, and land use and water use affect the water quality. Statistical analysis shows that streamflow, suspended-sediment, dissolved-iron, dissolved-orthophosphate-phosphorus, dissolved-sodium, dissolved-sulfate, and dissolved-manganese concentrations, specific conductance, and pH are highly variable among most stations. Dissolved-radium-226 concentration is the least variable among stations. A trend in one or more water quality constituents for the time period, October 1, 1973, through September 30, 1981, was detected at 15 out of 36 stations tested. The NASQAN stations Animas River at Farmington and San Juan River at Shiprock, New Mexico, record large volumes of flow that represent an integration of the flow from many upstream tributaries. The data collected do not represent what is occurring at specific points upstream in the basin, but do provide accurate information on how water quality is changing over time at the station location. A water quality, streamflow model would be necessary to predict accurately what is occurring simultaneously in the entire basin. (USGS)

In August 2015, 3 million gallons of acidic mine water flooded into a mountain stream, then flowed into the Animas River and the San Juan River. Downstream communities in Colorado, New Mexico and Utah watched in shock as the rivers on which they depend turned an unworldly orange color. As a result, water color currently drives public concern about river health. Data collected by the US Environmental Protection Agency and local and state public health indicate that water color does not correspond with health risk. Health risk is driven by river chemistry that cannot be seen, and river chemistry and quantity vary seasonally and due to precipitation events. Rivers have a pulse, one that is both regular and irregular, some aspects of which can be seen and others that cannot be seen. As a science communicator, I wanted to know if art could communicate the `pulse of the river', helping people to understand the dynamic quality of mountain rivers, and why scientific data is needed to determine health risk. Brian's vision was to do this through sound with real-time data on river water chemistry generating tones so that we can hear what we can't see. Through art, complex data on our world and how it is changing can be shared, reach more people, and lead to new dialogue. These conversations are much needed as we work to manage for global environmental issues.
Effects of Brazilian scorpion venoms on the central nervous system.
Nencioni, Ana Leonor Abrahão; Neto, Emidio Beraldo; de Freitas, Lucas Alves; Dorce, Valquiria Abrão Coronado
2018-01-01
In Brazil, the scorpion species responsible for most severe incidents belong to the Tityus genus and, among this group, T. serrulatus , T. bahiensis , T. stigmurus and T. obscurus are the most dangerous ones. Other species such as T. metuendus , T. silvestres, T. brazilae , T. confluens , T. costatus , T. fasciolatus and T. neglectus are also found in the country, but the incidence and severity of accidents caused by them are lower. The main effects caused by scorpion venoms - such as myocardial damage, cardiac arrhythmias, pulmonary edema and shock - are mainly due to the release of mediators from the autonomic nervous system. On the other hand, some evidence show the participation of the central nervous system and inflammatory response in the process. The participation of the central nervous system in envenoming has always been questioned. Some authors claim that the central effects would be a consequence of peripheral stimulation and would be the result, not the cause, of the envenoming process. Because, they say, at least in adult individuals, the venom would be unable to cross the blood-brain barrier. In contrast, there is some evidence showing the direct participation of the central nervous system in the envenoming process. This review summarizes the major findings on the effects of Brazilian scorpion venoms on the central nervous system, both clinically and experimentally. Most of the studies have been performed with T. serrulatus and T. bahiensis . Little information is available regarding the other Brazilian Tityus species.

Embora os Parâmetros Curriculares Nacionais do Ensino Médio (PCN-EM) e as orientações complementares a esses Parâmetros (PCN+) apontem a importância de uma abordagem significativa de conceitos relacionados à astronomia nas aulas de Física, muitos estudantes terminam o Ensino Médio (EM) sem compreender a razão de certos acontecimentos de origem celeste, ainda que estes façam parte de seu cotidiano. Este trabalho tem por objetivo analisar os conhecimentos básicos em astronomia dos alunos de EM da escola estadual Batista Renzi, bem como investigar os meios através dos quais estes conhecimentos foram adquiridos. Para tanto foi elaborado um questionário de múltipla escolha aplicado a 310 alunos distribuídos entre as três séries do EM dos períodos matutino e noturno. Dessa forma, observou-se que apenas 34,5% relacionaram as estações do ano à inclinação do eixo de rotação da Terra, 21,3% indicaram a influência gravitacional da Lua e do Sol como responsáveis pelo fenômeno das marés, 24,5% indicaram corretamente quais são os objetos celestes mais próximos da Terra, 36,1% identificaram ano-luz como uma medida de distância e 34,2% reconheceram uma estrela cadente como meteoro. Em contrapartida, 67,1% compreendiam a sucessão entre dia e noite, 73,9% identificaram o Sol como estrela e 52,3% relacionaram o Big Bang à origem do Universo. Além disso, foram comparadas as respostas de alunos de diferentes séries e períodos, observando-se, dentre outras coisas, que os estudantes do terceiro ano apresentam um percentual de acertos semelhante ao dos alunos do primeiro, caracterizando que a abordagem de tópicos relacionados à astronomia no EM não tem contribuído para uma maior compreensão dos fenômenos e conceitos.

Most fossil vertebrates in the Fruitland and Kirtland formations occur in two narrow stratigraphic intervals. The upper interval comprises the approximately 30 m-thick Naashoibito Member of the Kirtland formation. Fossiliferous localities within this interval are physically correlatable within the small and continuous outcrop belt of this unit. The lower fossiliferous interval comprises a 20 m-thick sequence between the stratigraphically highest, thick coal bed (1 m thick) in the Fruitland Formation and distinctive brown tabular sandstones in the lower Kirtland formation, which differ in color and geometry from adjacent sandstone bodies. Localities within this interval occur in physically discontinuous outcrops, principallymore » between Hunter Wash in the northwest and Coal Creek in the southeast. These localities can be correlated utilizing the upper Fruitland coal, the lower Kirtland sandstones, and a series of volcanic ashes. Measurement of 38 stratigraphic sections and examination of more than 100 subsurface geophysical logs has allowed detailed correlation between the principal areas of vertebrate-fossil occurrences in Hunter Wash and the Fossil Forest. The occurrence of fossils in the Naashoibito is related to energy of depositional environment. Farther north, coarser deposits of the McDermott Member of the Animas Formation, which represent proximal facies of the Naashoibito, lack abundant fossil vertebrates. The geographic extent of vertebrate fossils in the upper Fruitland and lower Kirtland coincides with the extent of the tabular brown sandstones in the lower Kirtland and is related to Laramide downwarping of the central San Juan basin.« less
Deglaciation and postglacial timberline in the San Juan Mountains, Colorado
Carrara, P.E.; Mode, W.N.; Rubin, M.; Robinson, S.W.
1984-01-01
Lake Emma, which no longer exists because of a mining accident, was a tarn in a south-facing cirque near the headwaters of the Animas River in the San Juan Mountains of southwestern Colorado. During the Pinedale glaciation, this area was covered by a large transection glacier centered over the Lake Emma region. Three radiocarbon dates on basal organic sediment from Lake Emma indicate that by ca. 15,000 yr B.P. this glacier, one of the largest in the southern Rocky Mountains, no longer existed. Twenty-two radiocarbon dates on Picea and Abies krummholz fragments in the Lake Emma deposits indicate that from ca. 9600 to 7800 yr B.P., from 6700 to 5600 yr B.P., and at 3100 yr B.P. the krummholz limit was at least 70 m higher than present. These data, in conjunction with Picea:Pinus pollen ratios from both the Lake Emma site and the Hurricane Basin site of J. T. Andrews, P. E. Carrara, F. B. King, and R. Struckenrath (1975, Quaternary Research 5, 173-197) suggest than from ca. 9600 to 3000 yr B.P. timberline in the San Juan Mountains was higher than present. Cooling apparently began ca. 3000 yr B.P. as indicated by decreases in both the percentage of Picea pollen and Picea:Pinus pollen ratios at the Hurricane Basin site (Andrews et al., 1975). Cooling is also suggested by the lack of Picea or Abies fragments younger than 3000 yr B.P. at either the Lake Emma or the Hurricane Basin site. ?? 1984.
Spatial interpolation schemes of daily precipitation for hydrologic modeling
Hwang, Y.; Clark, M.R.; Rajagopalan, B.; Leavesley, G.
2012-01-01
Distributed hydrologic models typically require spatial estimates of precipitation interpolated from sparsely located observational points to the specific grid points. We compare and contrast the performance of regression-based statistical methods for the spatial estimation of precipitation in two hydrologically different basins and confirmed that widely used regression-based estimation schemes fail to describe the realistic spatial variability of daily precipitation field. The methods assessed are: (1) inverse distance weighted average; (2) multiple linear regression (MLR); (3) climatological MLR; and (4) locally weighted polynomial regression (LWP). In order to improve the performance of the interpolations, the authors propose a two-step regression technique for effective daily precipitation estimation. In this simple two-step estimation process, precipitation occurrence is first generated via a logistic regression model before estimate the amount of precipitation separately on wet days. This process generated the precipitation occurrence, amount, and spatial correlation effectively. A distributed hydrologic model (PRMS) was used for the impact analysis in daily time step simulation. Multiple simulations suggested noticeable differences between the input alternatives generated by three different interpolation schemes. Differences are shown in overall simulation error against the observations, degree of explained variability, and seasonal volumes. Simulated streamflows also showed different characteristics in mean, maximum, minimum, and peak flows. Given the same parameter optimization technique, LWP input showed least streamflow error in Alapaha basin and CMLR input showed least error (still very close to LWP) in Animas basin. All of the two-step interpolation inputs resulted in lower streamflow error compared to the directly interpolated inputs. ?? 2011 Springer-Verlag.

OBJECTIVES: Declines in cognition and mobility are frequently observed in the elderly, and it has been suggested that the appearance of gait disorders in older individuals may constitute a marker of cognitive decline that precedes significant findings in functional performance screening tests. This study sought to evaluate the relationship between functional capacities and gait and balance in an elderly community monitored by the Preventive and Integrated Care Unit of the Hospital Adventista Silvestre in Rio de Janeiro, RJ, Brazil. METHODS: Elderly individuals (193 females and 90 males) were submitted to a broad geriatric evaluation, which included the following tests: 1) a performance-oriented mobility assessment (POMA) to evaluate gait; 2) a mini-mental state examination (MMSE); 3) the use of Katz and Lawton scales to assess functional capacity; 4) the application of the geriatric depression scale (GDS); and 5) a mini-nutritional assessment (MNA) scale. RESULTS: Reductions in MMSE, Katz and Lawton scores were associated with reductions in POMA scores, and we also observed that significant reductions in POMA scores were present in persons for whom the MMSE and Katz scores did not clearly indicate cognitive dysfunction. We also demonstrated that a decline in the scores obtained with the GDS and MNA scales was associated with a decline in the POMA scores. CONCLUSIONS: Considering that significant alterations in the POMA scores were observed prior to the identification of significant alterations in cognitive capacity using either the MMSE or the Katz systems, a prospective study seems warranted to assess the predictive capacity of POMA scores regarding the associated decline in functional capacity.

Resumo Anastomoses vasculares são procedimentos comuns realizados por grande parte dos cirurgiões e cujo treinamento ocorre principalmente em seres humanos, contrariando os princípios éticos vigentes. Esse fato se deve, sobretudo, à carência e ao alto custo relacionados aos atuais modelos de treinamento. Assim, este estudo visa avaliar a viabilidade de três vegetais para a realização de anastomoses vasculares. Foram utilizadas cinco unidades de cebolinha, vagem e feijão-verde. Em cada uma tentou-se realizar uma anastomose término-terminal. Conseguiu-se a realização da anastomose apenas na vagem e no feijão-verde. Contudo, por apresentar uma menor espessura, o feijão-verde assemelhou-se mais aos vasos humanos. PMID:29930658

Prospect Gulch is a major source of iron, aluminum, zinc, and other metals to Cement Creek. Information is needed to prioritize remediation and develop strategies for cleanup of historical abandoned mine sites in Prospect Gulch. Chemical-constituent loads were determined in Prospect Gulch, a high-elevation alpine stream in southwestern Colorado that is affected by natural acid drainage from weathering of hydro-thermally altered igneous rock and acidic metal-laden discharge from historical abandoned mines. The objective of the study was to identify metal sources to Prospect Gulch. A tracer solution was injected into Prospect Gulch during water-quality sampling so that loading of geochemical constituents could be calculated throughout the study reach. A thunderstorm occurred during the tracer study, hence, metal loads were measured for storm-runoff as well as for base flow. Data from different parts of the study reach represents different flow conditions. The beginning of the reach represents background conditions during base flow immediately upstream from the Lark and Henrietta mines (samples PG5 to PG45). Other samples were collected during storm runoff conditions (PG100 to PG291); during the first flush of metal runoff following the onset of rainfall (PG303 to PG504), and samples PG542 to PG700 were collected during low-flow conditions. During base-flow conditions, the percentage increase in loads for major constituents and trace metals was more than an order of magnitude greater than the corresponding 36 % increase in stream discharge. Within the study reach, the highest percentage increases for dissolved loads were 740 % for iron (Fe), 465 % for aluminum (Al), 500 % for lead (Pb), 380 % for copper (Cu), 100 % for sulfate (SO4), and 50 % for zinc (Zn). Downstream loads near the mouth of Prospect Gulch often greatly exceeded the loads generated within the study reach but varied by metal species. For example, the study reach accounts for about 6 % of the dissolved-Fe load, 13 % of the dissolved-Al load, and 18 % of the dissolved-Zn load; but probably contributes virtually all of the dissolved Cu and Pb. The greatest downstream gains in dissolved trace-metal loads occurred near waste-rock dumps for the historical mines. The major sources of trace metals to the study reach were related to mining. The major source of trace metals in the reach near the mouth is unknown, however is probably related to weathering of highly altered igneous rocks, although an unknown component of trace metals could be derived from mining sources The late-summer storm dramatically increased the loads of most dissolved and total constituents. The effects of the storm were divided into two distinct periods; (1) a first flush of higher metal concentrations that occurred soon after rainfall began and (2) the peak discharge of the storm runoff. The first flush contained the highest loads of dissolved Fe, total and dissolved Zn, Cu, and Cd. The larger concentrations of Fe and sulfate in the first flush were likely derived from iron hydroxide minerals such as jarosite and schwertmanite, which are common on mine dumps in the Prospect Gulch drainage basin. Peak storm runoff contained the highest measured loads of total Fe, and of total and dissolved calcium, magnesium, silica and Al, which were probably derived from weathering of igneous rocks and clay minerals in the drainage basin.

The aim of this study was to evaluate the effect of SEMA3A released from matrigel on implant fixation in ovariectomized (OVX) rats. Sixty female rats were subjected to bilateral ovariectomy. Twelve weeks later, rats were randomly divided into three groups according to implants they accepted: (1) Control, implants with distilled water; (2) Matrigel, implants with matrigel coating; (3) Matrigel + SEMA3A, implants with coating of SEMA3A suspended in matrigel. Implants were inserted in metaphysis of proximal tibiae in all animas bilaterally. In vitro release of SEMA3A was tested using enzyme linked immunosorbent assay. In vitro release of SEMA3A was detectable during the first 10 days, and a burst release of was observed during the first 3 days. No significant difference was observed between Control and Matrigel group. The protective effects of SEMA3A in matrigel on peri-implant bone, implant osseointegration and fixation was confirmed. Compared to matrigel alone, SEMA3A suspended in matrigel increased percent bone volume by 88.7% and 83.3% (p < 0.01), bone-to-implant contact ratio by 148.9% (p < 0.01), and 24.8% (p < 0.05), the maximal push-out force by 149.3% and 209.2% (p < 0.01) at 4 and 8 weeks after implant insertion, respectively. Surface modification with SEMA3A suspended in matrigel improved implant osseointegration and fixation in the proximal tibiae of OVX rats. © 2016 Wiley Periodicals, Inc.

[The concept of soul in the course of history. Thoughts on psyche, mind and awareness].
Hinterhuber, Hartmann
2002-10-31
This paper seeks to convey an insight into the interrelationships between body, soul and mind and to show how the concept of "soul" has evolved through the course of history. In German the word "soul" has a confusing array of meanings today. For most of us it comprises all of man's emotions, his awareness, constructive thought, drive, state of mind and spirit. The soul thus represents the essence of a person and his relationships to those closest to him. For many people the soul was and still is the principle of life, the breath of life and the force of life. The immortal soul escapes, leaves the body, is weighed and judged. At all times in history man has doggedly pursued the mysteries of self-awareness, the ultimate truth and the soul. What he found varied, depending on the age and the place. What the Hebrew Bible and the New Testament express in deep-seated metaphors, the Greek philosophers put into clear-cut words: their concept of soul was then largely integrated into Christian thought. Meister Eckhart describes the soul in mystically transfigured passion. C.G. Jung writes of the "animus and anima." Sigmund Freud uses the term "psyche." Radical materialism denies the existence and independence of the soul's processes. The questions where we come from and where we are going, why and what for, no longer find a common answer. Psychiatry, however, takes up the intellectual call of the time and replies to the challenges of the day. Thus, the search for the "soul", a search that occupies so many people, also always involves the search for the whole person.

Portable electronic devices play an important role in the management of type 1 diabetes mellitus. Electromagnetic interference from electronic devices has been shown to impair the function of an avalanche transceiver in search mode (but not in transmitting mode). This study investigates the influence of electromagnetic interference from diabetes devices on a searching avalanche beacon. The greatest distance at which an avalanche transceiver (in search mode) could accurately indicate the location of a transmitting transceiver was assessed when portable electronic devices (including an insulin pump and commonly used real-time continuous subcutaneous glucose monitoring system [rtCGMS]) were held in close proximity to each transceiver. The searching transceiver could accurately locate a transmitted signal at a distance of 30 m when used alone. This distance was unchanged by the Dexcom G4 rtCGMS, but was reduced to 10 m when the Medtronic Guardian rtCGMS was held close (within 30 cm) to the receiving beacon. Interference from the Animas Vibe insulin pump reduced this distance to 5 m, impairing the searching transceiver in a manner identical to the effect of a cell phone. Electromagnetic interference produced by some diabetes devices when held within 30 cm of a searching avalanche transceiver can impair the ability to locate a signal. Such interference could significantly compromise the outcome of a companion rescue scenario. Further investigation using other pumps and rtCGMS devices is required to evaluate all available diabetes electronics. Meantime, all electronic diabetes devices including rtCGMS and insulin pumps should not be used within 30 cm of an avalanche transceiver. Copyright © 2015 Wilderness Medical Society.

This report is the result of a geochemical investigation of the former uranium mill and tailings site at Durango, Colorado. This is one in a series of site specific geochemical investigations performed on the inactive uranium mill tailings included in the UMTRA Project. The objectives of the investigation are to characterize the geochemistry, to determine the contaminant distribution resulting from the former milling activities and tailings, and to infer chemical pathways and transport mechanisms from the contaminant distribution. The results will be used to model contaminant migration and to develop criteria for long-term containment media such as a cover systemmore » which is impermeable to contaminant migration. This report assumes a familiarity with the hydrologic conditions of the site and the geochemical concepts underlying the investigation. The results reported are based on a one-time sampling of waters and solid material from the background, the area adjacent to the site, and the site. The solid samples are water extracted remove easily soluble salts and acids extracted to remove cabonates and hydroxides. The water extracts and solid samples were analyzed for the major and trace elements. A limited number of samples were analyzed for radiological components. The report includes the methods of sampling, sample processing, analysis, and data interpretation. Three major conclusions are: (1) carbonate salts and low TDS characterize the tailings; (2) the adjacent area and raffinate ponds contain contaminants deposited by a single event of fluid permeation of the soils; and (3) the Animas River adjacent to the site has elevated gross alpha activity attributed to /sup 226/Ra in the sediments derived from the tailings or milling activities.« less

From the Preface: There are thousands of abandoned or inactive mines on or adjacent to public lands administered by the U.S. Forest Service, Bureau of Land Management, and National Park Service. Mine wastes from many of these abandoned mines adversely affect resources on public lands. In 1995, an interdepartmental work group within the Federal government developed a strategy to address remediation of the many abandoned mines on public lands. This strategy is based on using a watershed approach to address the abandoned mine lands (AML) problem. The USGS, working closely with the Federal land-management agencies (FLMAs), is key for the success of this watershed approach. In support of this watershed approach, the USGS developed an AML Initiative with pilot studies in the Boulder River in Montana and the Animas River in Colorado. The goal of these studies is to design and implement a reliable strategy that will supply the scientific information to the FLMAs so that land managers can develop efficient and cost-effective remediation of AML. The symposium 'Science for Watershed Decisions on Abandoned Mine Lands: Review of Preliminary Results' held in Denver, Colorado, on February 4-5, 1998, provided the FLMAs a first look at the techniques, data, and interpretations being generated by the USGS pilot studies. This multidisciplined effort already is proving very valuable to land managers in making science-based AML cleanup decisions and will continue to be of increasing value as additional and more complete information is obtained. Ongoing interaction between scientists and land managers is essential to insure the efficient continuation and success of AML cleanup efforts.

The Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus) breeds in desert grasslands of southeastern Arizona and southwestern New Mexico in the US, and in adjacent parts of northern Sonora and Chihuahua, Mexico. Roads that were surveyed in 1982 and 1987 in Arizona and New Mexico were relocated and roadside survey protocols were repeated in 2004 and 2005 to identify changes in distribution or abundance of the subspecies during the subsequent 17 yr. The Sonoita and San Rafael valleys in Arizona and the Animas Valley in New Mexico remain as primary population centers, supporting the highest mean numbers of singing males per stop, as well as the largest populations of Arizona Grasshopper Sparrows in the US. Mean number of singing males per stop was highest in the San Rafael Valley. Mean number of singing males per survey stop showed an increasing pattern from 1982–1987 and a subsequent decline to the present (2004–2005). Present bird densities are intermediate in value between 1982 and 1987 values. Small populations remain in the Altar, San Pedro, Sulphur Springs, and San Bernardino valleys in Arizona. The valleys evaluated in this and historical surveys represent the areas in which almost all Arizona Grasshopper Sparrows breed in the US; if any additional areas exist, they support peripheral, small, or remnant populations. Although historic, current, and future land use, and current and future threats differ among valleys, the primary factors posing threats to the future of Arizona Grasshopper Sparrow populations appear to be loss and/or degradation of habitat due to exurban development, overgrazing, and the effects of long-term drought.

A scheme to discriminate and identify materials having overlapping spectral absorption features has been developed and tested based on the U.S. Geological Survey (USGS) Tetracorder system. The scheme has been applied to remotely sensed imaging spectroscopy data acquired by the Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) instrument. This approach was used to identify the minerals calcite, epidote, and chlorite in the upper Animas River watershed, Colorado. The study was motivated by the need to characterize the distribution of calcite in the watershed and assess its acid-neutralizing potential with regard to acidic mine drainage. Identification of these three minerals is difficult because their diagnostic spectral features are all centered at 2.3 ??m, and have similar shapes and widths. Previous studies overestimated calcite abundance as a result of these spectral overlaps. The use of a reference library containing synthetic mixtures of the three minerals in varying proportions was found to simplify the task of identifying these minerals when used in conjunction with a rule-based expert system. Some inaccuracies in the mineral distribution maps remain, however, due to the influence of a fourth spectral component, sericite, which exhibits spectral absorption features at 2.2 and 2.4 ??m that overlap the 2.3-??m absorption features of the other three minerals. Whereas the endmember minerals calcite, epidote, chlorite, and sericite can be identified by the method presented here, discrepancies occur in areas where all four occur together as intimate mixtures. It is expected that future work will be able to reduce these discrepancies by including reference mixtures containing sericite. ?? 2004 Elsevier Inc. All rights reserved.

Raptorial birds harbor a variety of ectoparasites and the mayority of them are host specific. The aim of this study was to identify the ectoparasites of captive birds of prey from Mexico, as well as to verify their impact in the health of infested birds. Raptorial birds were confiscated and kept in captivity at the Centro de Investigación y Conservación de Vida Silvestre (CIVS) in Los Reyes La Paz, Mexico State. Seventy-four birds of prey (66 Falconiformes and eigth Strigiformes) of 15 species were examined for the presence of ectoparasites. We examined both juvenile and adult birds from both sexes. The overall prevalence was 16.2%; 66.7% of raptors were infested with a single type of external parasite. Lice were the most prevalent ectoparasites (91.7%), followed by feather mites and fleas (8.3%). Degeeriella fulva (72.7%), Craspedorrhynchus sp. (45.4%) and Strigiphilus aitkeni (9.1%) (Ischnocera, Philopteridae) were recovered from wings, head and neck regions of red-tailed hawk (Buteo jamaicensis), Swainson's hawk (B. swainsoni), Harris's hawk (Parabuteo unicinctus) and Barn owl (Tyto alba). Low lice infestation level was observed. Nymphs and females of feather mites Kramerella sp. (Pterolichoidea, Kramerellidae) were recovered solely from Barn owl (T. alba); while one Caracara (Caracara cheriway) was infested by the sticktight flea Echidnophaga gallinacea (Siphonaptera, Pulicidae). No clinical signs were observed in any infested bird. Probably the periodic use of organophosphorates was responsible of the low prevalence and lice infestation levels. The diversity of external parasites illustrates the importance of detailed revision of incoming and long-term captive raptors as part of responsible captive management. Five new hosts and geographic records are presented.

En esta investigacion se estudio el fenomeno del conocimiento de contenido y el conocimiento curricular de maestros de matermaticas y como estos dos componentes se reflejan en su conocimiento pedagogico del contenido. El conocimiento de contenido es el conocimiento que tienen los maestros de los contenidos de una disciplina y sobre la estructura de su organizacion (Shulman, 1986). El conocimiento curricular es el conocimiento que los maestros poseen sobre los componentes de un curriculo disenado para ensenar un topico de una materia especifica a un nivel particular, la variedad de instrumentos instruccionales disponibles para implementar el mismo y como utilizar los instrumentos curriculares disponibles (Ball & Bass, 2003; Choppin, 2009; Hill, Rowan, & Ball, 2005). Este estudio se enmarca en el paradigma cualitativo, teniendo como diseno el estudio fenomenologico (Lucca y Berrios, 2009; McMillan, 2004). Los participantes fueron seis maestros de matermaticas del nivel superior (10mo a 12mo grado). Al momento de la investigacion los participantes ensenaban en escuelas publicas o privadas de Puerto Rico. Para recolectar la informacion se utilizo un grupo focal en donde los maestros resolvieron seis ejercicios matematicos y posteriormente reflexionaron en forma grupal sobre las soluciones.

La isla de Puerto Rico, localizada al noreste del Mar Caribe y sus islas principales, Vieques, Culebra e Isla de Mona, poseen humedales en abundancia . El clima subtropical, la lluvia abundante y las complejas formas topográficas y geológicas de estas islas dan origen a los humedales, que varían desde los raros e inusuales bosques cubiertos por nubes en las tierras altas, hasta los extensos manglares, yerbas marinas y arrecifes de coral a lo largo de las costas Norte y Sur. Sin embargo, los humedales en Puerto Rico han disminuido en los últimos siglos como resultado del aumento en el desarrollo agrícola, poblacional y turístico. Algunos tipos de humedales como los bosques de palo de pollo (Pterocarpus officinalis) se han reducido a sólo unos pocos remanentes (figura 1).Biológicamente hablando, los humedales de las islas están entre las áreas más productivas. Los humedales asociados con el bosque pluvial en las tierras altas del interior de Puerto Rico contienen varias plantas raras y especies de animales que no se encuentran en otras partes de la Isla. El agua de escorrentía proveniente de los humedales en las partes altas de la Isla proveen una fuente de agua que utilizan varias ciudades para abasto público. Los humedales costeros como los mangles, los colchones de yerbas marinas y los arrecifes de coral proveen áreas para la reproducción y crianza de varios peces, crustáceos y otras especies en la cadena alimenticia (López y otros, 1988). De esta manera, los humedales costeros contribuyen a la productividad biológica de las aguas llanas del mar alrededor de las islas . Los humedales también estabilizan las costas atrapando y reteniendo sedimentos no consolidados y amortiguan la acción de las olas y de las tormentas que tienen el potencial de causar daños en la zona.El valor de los humedales de Puerto Rico para la vida silvestre está muy bien documentado . Por ejemplo, las salinas de Cabo Rojo, en la costa suroeste, proveen áreas para el

Farmland abandonment takes place across the world due to socio-economic and ecological drivers. In Europe agricultural and environmental policies aim to prevent abandonment and halt ecological succession. Ecological rewilding has been recently proposed as an alternative strategy. We developed a framework to assess opportunities for rewilding across different dimensions of wilderness in Europe. We mapped artificial light, human accessibility based on transport infrastructure, proportion of harvested primary productivity (i.e., ecosystem productivity appropriated by humans through agriculture or forestry), and deviation from potential natural vegetation in areas projected to be abandoned by 2040. At the continental level, the levels of artificial light were low and the deviation from potential natural vegetation was high in areas of abandonment. The relative importance of wilderness metrics differed regionally and was strongly connected to local environmental and socio-economic contexts. Large areas of projected abandonment were often located in or around Natura 2000 sites. Based on these results, we argue that management should be tailored to restore the aspects of wilderness that are lacking in each region. There are many remaining challenges regarding biodiversity in Europe, but megafauna species are already recovering. To further potentiate large-scale rewilding, Natura 2000 management would need to incorporate rewilding approaches. Our framework can be applied to assessing rewilding opportunities and challenges in other world regions, and our results could guide redirection of subsidies to manage social-ecological systems.

This study was designed to study patients with intolerance to pesticide smells. Ten subjects chosen were complaining of vague symptoms such as headache, dizziness, fatigue, nausea, vomiting, abdominal pain, myalgia, flu-like symptoms, etc., whenever exposed to the pesticide smells even at low intensity. To determine whether the etiology of this kind of pesticide hypersensitivity was of organic or psychiatric nature, all the subjects underwent tests as follows: complete blood cell count, urinalysis, and blood chemistry as routine tests; esophogastroduodenoscopy and abdomen ultrasonography for the gastrointestinal symptoms; chest x-ray, pulmonary function tests, and electrocardiography for the respiratory and/or cardiac symptoms; nerve conduction velocity and brain magnetic resonance imaging (MRI) for peripheral and central nerve system symptoms; and K-WAIS, Rey-Kim memory test, Rorschach, Mini Mental State Examination (MMSE), and Minnesota Multiphasic Personality Inventory (MMPI) for psychoanalysis. Of the 10 cases in which the chief complaint was headache, symptoms of two cases were caused by maxillary sinusitis. Another two showed typical multiple chemical sensitivity (MCS) or idiopathic environmental intolerance (IEI). Six out of the 10 cases, whose symptoms closely resembled the others, did not conclusively meet the criteria of classic MCS or IEI. The subjects of this case shared vague fears, both fear of pesticides and hypochondriasis. Some subjects faced financial insecurity and social uncertainty; others felt uneasy about the future of their farming life. Thus, to help verify the causes of MCS or IEI, which is strongly suggestive of pesticide smells, diagnosis needs a dual approach: on the anima and soma. Psychoanalysis can delve into the mental status of the patients to see whether the patients are aware of their symptoms. Clinical tests can see through the physical structure and functions of the organs on which patients' complaints are centered.

The Abandoned Mine Lands (AML) Initiative is part of a larger strategy of the U.S. Department of the Interior and the U.S. Department of Agriculture to clean up Federal lands contaminated by abandoned mines.Thousands of abandond hard-rock metal mines (such as gold, copper, lead, and zinc) have left a dual legacy across the Western United States. They reflect the historic development of the west, yet at the same time represent a possible threat to human health and local ecosystems.Abandoned Mine Lands (AML) are areas adjacent to or affected by abandoned mines. AML's often contain unmined mineral deposits, mine dumps (the ore and rock removed to get to the ore deposits), and tailings (the material left over from the ore processing) that contaminate the surrounding watershed and ecosystem. For example, streams near AML's can contain metals and (or) be so acidic that fish and aquatic insects cannot live in them.Many of these abandoned hard-rock mines are located on or adjacent to public lands administered by the Bureau of Land Management, National Park Service, and U.S. Forest Service. These federal land management agencies and the USGS are committed to mitigating the adverse effects that AML's can have on water quality and stream habitats.The USGS AML Initiative began in 1997 and will continue through 2001 in two pilot watersheds - the Boulder River basin in southwestern Montana and the upper Animas River basin in southwestern Colorado. The USGS is providing a wide range of scientific expertise to help land managers minimize and, where possible, eliminate the adverse environmental effects of AML's. USGS ecologists, geologists, water quality experts, hydrologists, geochemists, and mapping and digital data collection experts are collaborating to provide the scientific knowledge needed for an effective cleanup of AML's.

This study assessed the accuracy and reliability of three continuous glucose monitoring (CGM) systems. We studied the Animas® (West Chester, PA) Vibe™ with Dexcom® (San Diego, CA) G4™ version A sensor (G4A), the Abbott Diabetes Care (Alameda, CA) Freestyle® Navigator I (NAV), and the Medtronic (Northridge, CA) Paradigm® with Enlite™ sensor (ENL) in 20 patients with type 1 diabetes mellitus. All systems were investigated both in a clinical research center (CRC) and at home. In the CRC, patients received a meal with a delayed and increased insulin dose to induce a postprandial glucose peak and nadir. Hereafter, randomization determined which two of the three systems would be worn at home until the end of functioning, attempting use beyond manufacturer-specified lifetime. Patients performed at least five reference finger sticks per day. An analysis of variance was performed on all data points ≥15 min apart. Overall average mean absolute relative difference (MARD) (SD) measured at the CRC was 16.5% (14.3%) for NAV and 16.4% (15.6%) for ENL, outperforming G4A at 20.5% (18.2%) (P<0.001). Overall MARD when assessed at home was 14.5% (16.7%) for NAV and 16.5 (18.8%) for G4A, outperforming ENL at 18.9% (23.6%) (P=0.006). Median time until end of functioning was similar: 10.0 (1.0) days for G4A, 8.0 (3.5) days for NAV, and 8.0 (1.5) days for ENL (P=0.119). In the CRC, G4A was less accurate than NAV and ENL sensors, which seemed comparable. However, at home, ENL was less accurate than NAV and G4A. Moreover, CGM systems often show sufficient accuracy to be used beyond manufacturer-specified lifetime.

Spatial scale is one of the main considerations in hydrological modeling of snowmelt in mountainous areas. The size of model elements controls the degree to which variability can be explicitly represented versus what needs to be parameterized using effective properties such as averages or other subgrid variability parameterizations that may degrade the quality of model simulations. For snowmelt modeling terrain parameters such as slope, aspect, vegetation and elevation play an important role in the timing and quantity of snowmelt that serves as an input to hydrologic runoff generation processes. In general, higher resolution enhances the accuracy of the simulation since fine meshes represent and preserve the spatial variability of atmospheric and surface characteristics better than coarse resolution. However, this increases computational cost and there may be a scale beyond which the model response does not improve due to diminishing sensitivity to variability and irreducible uncertainty associated with the spatial interpolation of inputs. This paper examines the influence of spatial resolution on the snowmelt process using simulations of and data from the Animas River watershed, an alpine mountainous area in Colorado, USA, using an unstructured distributed physically based hydrological model developed for a parallel computing environment, ADHydro. Five spatial resolutions (30 m, 100 m, 250 m, 500 m, and 1 km) were used to investigate the variations in hydrologic response. This study demonstrated the importance of choosing the appropriate spatial scale in the implementation of ADHydro to obtain a balance between representing spatial variability and the computational cost. According to the results, variation in the input variables and parameters due to using different spatial resolution resulted in changes in the obtained hydrological variables, especially snowmelt, both at the basin-scale and distributed across the model mesh.

Resumen La revisión ética de un Ensayo Clínico1 que incluye a niñas/os y adolescentes en calidad de participantes, debe centrar su mirada en aspectos relacionados con la vulnerabilidad inherente a esa etapa de la vida, condición que se nutre de elementos biológicos, emocionales, de justicia y de equidad, entre otros. Sin embargo, la visión sugerida en este caso y sin desoír las características mencionadas, es la que busca profundizar en uno de los actores del proceso de investigación: el Ensayo Clínico. El objetivo es poder determinar la presencia o no de “zonas frágiles o de puntos débiles” en su interior, los que al ser individualizados y especialmente considerados, contribuyan a mejorar la calidad de la revisión ética de las investigaciones que son llevadas a cabo en niñas/os y adolescentes.

Resumo A síndrome antifosfolipíde (SAF) é uma doença autoimune sistêmica caracterizada por trombose arterial ou venosa recorrente e/ou morbidade gestacional e pela presença dos anticorpos antifosfolipídeos, podendo apresentar outras manifestações vasculares, como microangiopatia, arteriopatia crônica e SAF catastrófica. Determinados testes laboratoriais para a síndrome (por exemplo, o anticoagulante lúpico) podem sofrer interferência do uso de medicações anticoagulantes, dificultando o diagnóstico. A fisiopatologia da SAF é complexa, sendo enumerados no texto diversos mecanismos patogênicos relacionados à coagulação, ao endotélio e às plaquetas. Por fim, discutimos o tratamento da SAF de acordo com a presença e o tipo de manifestações clínicas, o uso dos anticoagulantes orais diretos e o manejo perioperatório de pacientes com SAF.

The South American fruit fly Anastrepha fraterculus (Wiedemann) is one of the most destructive fruit pests in this region, infesting major fruit crops. Implementation of the sterile insect technique (SIT) as part of an area-wide integrated approach against this species requires information on the survival of mass-reared and sterilized insects in the field and their ability to mate with wild females. The survival rates in field cages of both non-irradiated and irradiated laboratory flies were compared with that of wild flies. Both types of laboratory flies survived longer than their wild counterparts over the 8 days under the experimental conditions.more » The irradiation dose (70 Gy) did not affect survival of the laboratory reared flies. Our results improve the prospect of integrating the SIT into the control of A. fraterculus populations in Argentina.

La implementacion de la Tecnica del Insecto Esteril (TIE) como parte de un manejo integrado en areas extensivas contra esta especie requiere ensayos que demuestren que los insectos producidos en forma masiva y esterilizados son capaces de sobrevivir en el campo y aparearse con las hembras silvestres. Se comparo la supervivencia de individuos de una linea de laboratorio, tanto irradiados como no irradiados con la de individuos de una poblacion natural. Los dos tratamientos de moscas de laboratorio sobrevivieron mas tiempo que las salvajes durante los 8 dias y en las condiciones ensayadas. La dosis de radiacion (70 Gy.) no afecto la supervivencia de las moscas criadas en laboratorio. Nuestros resultados mejoran las perspectivas de integrar la TIE en el control de las poblaciones argentinas de A. fraterculus. (author)« less

Investigations within the Silverton caldera, in southwestern Colorado, used a combination of traditional geological mapping, alteration-assemblage mapping, and aqueous geochemical sampling that showed a relationship between geological and hydrologic features that may be used to better understand the provenance and evolution of the water. Veins containing fluorite, huebnerite, and elevated molybdenum concentrations are temporally and perhaps genetically associated with the emplacement of high-silica rhyolite intrusions. Both the rhyolites and the fluorite-bearing veins produce waters containing elevated concentrations of F-, K and Be. The identification of water samples with elevated F/Cl molar ratios (> 10) has also aided in the location of water draining F-rich sources, even after these waters have been diluted substantially. These unique aqueous geochemical signatures can be used to relate water chemistry to key geological features and mineralized source areas. Two examples that illustrate this relationship are: (1) surface-water samples containing elevated F-concentrations (> 1.8 mg/l) that closely bracket the extent of several small high-silica rhyolite intrusions; and (2) water samples containing elevated concentrations of F-(> 1.8 mg/ l) that spatially relate to mines or areas that contain late-stage fluorite/huebnerite veins. In two additional cases, the existence of high F-concentrations in water can be used to: (1) infer interaction of the water with mine waste derived from systems known to contain the fluorite/huebnerite association; and (2) relate changes in water quality over time at a high elevation mine tunnel to plugging of a lower elevation mine tunnel and the subsequent rise of the water table into mineralized areas containing fluorite/huebnerite veining. Thus, the unique geochemical signature of the water produced from fluorite veins indicates the location of high-silica rhyolites, mines, and mine waste containing the veins. Existence of high F-concentrations along with K and Be in water in combination with other geological evidence may be used to better understand the provenance of the water. ?? 2009 AAG/Geological Society of London.

We present in this work the development of astronomy in Uruguay since the colony times up to the present, stressing in particular those aspects related to the formal as well as informal teaching of astronomy. The first antecedents of astronomical studies in our country go back to the beginnings of the XVIIIth century related to the scientific expeditions from Europe coming to our shores. The teaching of astronomy was generalized at the high school level as soon as the end of the XIXth century, while itsintroduction at the university level happened much later, around the middle of the last century. We analyze the current situation of this subject, its problems, and some measures to strengthen its development. Se presenta en este trabajo el desarrollo de la astronomía en el Uruguay desde la época colonial hasta el presente, destacando en particular los aspectos vinculados a su enseñanza tanto formal como informal. Los primeros antecedentes de estudios astronómicos datan de la época colonial relacionados con las expediciones científicas del Viejo Mundo que llegaban a nuestras costas. La enseñanza de la Astronomía se generalizó en el ámbito de los estudios secundarios ya a fines del siglo XIX, mientras que en la Universidad su arribo fue mucho más tardío, a mediados del siglo pasado.

íferos Silvestres Causantes de Daños Resumen Muchas poblaciones de mamíferos amenazados persisten fuera de áreas protegidas formales y su supervivencia depende de la buena voluntad de las comunidades que coexisten con ellos. Un entendimiento de las posturas, y específicamente de la tolerancia, de los individuos y las comunidades y los factores que los determinan es fundamental para diseñar estrategias que alivien el conflicto humano – vida silvestre. Llevamos a cabo un meta-análisis para identificar los factores que afectaron las posturas hacia cuatro grupos de mamíferos terrestres. Los elefantes (65%) provocaron las posturas más positivas. Los siguieron los primates (55%), los ungulados (53%) y los carnívoros (44%). Los residentes urbanos presentaron las posturas más positivas (80%), seguidos por los granjeros comerciales (51%) y los granjeros comunales (26%). Un índice de tolerancia a los daños mostró que la tolerancia humana a los ungulados y primates fue proporcional a la probabilidad de experimentar daños mientras que los elefantes provocaron niveles de tolerancia más altos de lo esperado y los carnívoros provocaron niveles de tolerancia más bajos de lo esperado. Contrario a la sabiduría convencional, experimentar daños no fue siempre el factor dominante para determinar las posturas. Los granjeros comunales tuvieron una baja probabilidad de ser positivos hacia los carnívoros independientemente de la probabilidad de experimentar daños, mientras que los granjeros comerciales y los residentes urbanos tuvieron mayor probabilidad de ser positivos hacia los carnívoros independientemente de los daños. Los residentes urbanos tuvieron mayor probabilidad de ser positivos hacia los ungulados, los elefantes y los primates cuando la probabilidad de daños fue baja, pero no cuando fue alta. Los granjeros comerciales y comunales tuvieron una mayor probabilidad de ser positivos hacia los ungulados, los primates y los elefantes independientemente de la probabilidad de

To validate a video containing image representations of clinical signs and symptoms of sexually transmitted infections expressed in Libras. Methodology development study conducted in an audio communication school. Thirty-six deaf people were selected. A video containing image representations of clinical signs and symptoms of sexually transmitted infections expressed in Libras was produced. Semantic validation was performed by deaf students and content validation by three judges who are Libras experts. The validation results were subjected to the Content Validity Index, where an index score > 0.80/80% was considered as agreement among judges. Seven signs and symptoms related to sexually transmitted infections were validated and obtained satisfactory Content Validity Indexes, most of them with 100% representativeness and agreement. The validation process made the expressions of signs and symptoms related to sexually transmitted infections represented in Libras valid for establishing effective communication in the area of the study, turning it into a care tool that facilitates and standardizes communication with deaf people through Libras.

The JewelPUMP™ (JP) is a new patch pump based on a microelectromechanical system that operates without any plunger. The study aimed to evaluate the infusion accuracy of the JP in vitro and in vivo. For the in vitro studies, commercially available pumps meeting the ISO standard were compared to the JP: the MiniMed® Paradigm® 712 (MP), Accu-Chek® Combo (AC), OmniPod® (OP), Animas® Vibe™ (AN). Pump accuracy was measured over 24 hours using a continuous microweighing method, at 0.1 and 1 IU/h basal rates. The occlusion alarm threshold was measured after a catheter occlusion. The JP, filled with physiological serum, was then tested in 13 patients with type 1 diabetes simultaneously with their own pump for 2 days. The weight difference was used to calculate the infused insulin volume. The JP showed reduced absolute median error rate in vitro over a 15-minute observation window compared to other pumps (1 IU/h): ±1.02% (JP) vs ±1.60% (AN), ±1.66% (AC), ±2.22% (MP), and ±4.63% (OP), P < .0001. But there was no difference over 24 hours. At 0.5 IU/h, the JP was able to detect an occlusion earlier than other pumps: 21 (19; 25) minutes vs 90 (85; 95), 58 (42; 74), and 143 (132; 218) minutes (AN, AC, MP), P < .05 vs AN and MP. In patients, the 24-hour flow error was not significantly different between the JP and usual pumps (–2.2 ± 5.6% vs –0.37 ± 4.0%, P = .25). The JP was found to be easier to wear than conventional pumps. The JP is more precise over a short time period, more sensitive to catheter occlusion, well accepted by patients, and consequently, of potential interest for a closed-loop insulin delivery system.

In De Motu Cordis, W. Harvey sometimes waxes lyrical on the primacy of the heart. In his another treatise, De Generatione, however, he insists on the primacy of the blood. The "conversion theory" explained this discrepancy with Harvey's conversion as caused by his discovery of the antiquity of the blood. But Whitterridge showed that Harvey had already described the antiquity of the blood in his earliest notebook, Prelectiones. As shown in this article, Harvey's observation was not a mere accidental discovery; based on the "classic questions", it was continuously and persistently conducted until he was assured of having seen the blood to exist prior to the pulse and movement to occur in the blood. While this crucial observation was not yet made in Prelectiones and De Motu Cordis, it was described as crucial evidence of the theory of the primacy of the blood in De Generatione, in which this new theory was introduced as an independent topic of the exercitatio. The topic of the order of the generation was a crucial issue in the theoretical medicine of Harvey's days. That is, the Aristotelian primacy of the heart had been seriously challenged by the Galenic tripartite theory which pursued the antiquity of three organs. Harvey's theory, or the primacy of the blood, seems to consists with Aristotle's premise, in that it asserts the existence of the only source of all functions in living animals. Harvey's theory, however, was confronted, on the other hand, with Aristotle's another inconsistency, namely, the issue of two definitions about anima. We must consider the construction and strategy of the exercitatio in Harvey's days to understand the exact meaning of the primacy of the heart in De Motu Cordis. In De Motu Cordis, Harvey did not use the primacy of the heart in a central part of the exercitatio, namely, in confirming his unprecedented theory, the circulation of the blood, but he settled this Aristotelian premise in a marginal part, namely, in ratiocinating the final

Daily precipitation and maximum and minimum temperature time series from a Regional Climate Model (RegCM2) were used as input to a distributed hydrologic model for a rainfall-dominated basin (Alapaha River at Statenville, Georgia) and three snowmelt-dominated basins (Animas River at Durango, Colorado; East Fork of the Carson River near Gardnerville, Nevada; and Cle Elum River near Roslyn, Washington). For comparison purposes, spatially averaged daily data sets of precipitation and maximum and minimum temperature were developed from measured data. These datasets included precipitation and temperature data for all stations that are located within the area of the RegCM2 model output used for each basin, but excluded station data used to calibrate the hydrologic model. Both the RegCM2 output and station data capture the gross aspects of the seasonal cycles of precipitation and temperature. However, in all four basins, the RegCM2- and station-based simulations of runoff show little skill on a daily basis (Nash-Sutcliffe (NS) values ranging from 0.05-0.37 for RegCM2 and -0.08-0.65 for station). When the precipitation and temperature biases are corrected in the RegCM2 output and station data sets (Bias-RegCM2 and Bias-station, respectively) the accuracy of the daily runoff simulations improve dramatically for the snowmelt-dominated basins. In the rainfall-dominated basin, runoff simulations based on the Bias-RegCM2 output show no skill (NS value of 0.09) whereas Bias-All simulated runoff improves (NS value improved from -0.08 to 0.72). These results indicate that the resolution of the RegCM2 output is appropriate for basin-scale modeling, but RegCM2 model output does not contain the day-to-day variability needed for basin-scale modeling in rainfall-dominated basins. Future work is warranted to identify the causes for systematic biases in RegCM2 simulations, develop methods to remove the biases, and improve RegCM2 simulations of daily variability in local climate.

Biodiversity elements with narrow niches and restricted distributions (i.e., 'short range endemics,' SREs) are particularly vulnerable to climate change. The New Mexico Ridge-nosed Rattlesnake (Crotalus willardi obscurus, CWO), an SRE listed under the U.S. Endangered Species Act within three sky islands of southwestern North America, is constrained at low elevation by drought and at high elevation by wildfire. We combined long-term recapture and molecular data with demographic and niche modeling to gauge its climate-driven status, distribution, and projected longevity. The largest population (Animas) is numerically constricted (N = 151), with few breeding adults (Nb = 24) and an elevated inbreeding coefficient (ΔF = 0.77; 100 years). Mean home range (0.07 km2) is significantly smaller compared to other North American rattlesnakes, and movements are within, not among sky islands. Demographic values, when gauged against those displayed by other endangered/Red-Listed reptiles [e.g., Loggerhead Sea Turtle (Caretta caretta)], are either comparable or markedly lower. Survival rate differs significantly between genders (female

The upper Prickly Pear Creek watershed encompasses the upstream 15 miles of Prickly Pear Creek, south of Helena, Montana (fig. 1). The headwaters of Prickly Pear Creek and its tributaries (Beavertown Creek, Clancy Creek, Dutchman Creek, Golconda Creek, Lump Gulch, Spring Creek, and Warm Springs Creek) are primarily in the Helena National Forest, whereas the central part of the watershed primarily is within either Bureau of Land Management (BLM) or privately owned property. Three mining districts are present in the upper Prickly Pear Creek watershed: Alhambra, Clancy, and Colorado. Numerous prospects, adits, tailings piles, mills, dredge piles, and mines (mostly inactive) are located throughout the watershed. These districts contain polymetallic (Ag, Au, Cu, Pb, Zn) vein deposits and precious-metal (Au-Ag) vein and disseminated deposits that were exploited beginning in the 1860’s. Placer Au deposits in the major streams were extensively mined in the late 1800’s and early 1900’s.As part of a cooperative effort with Federal land management agencies, the U.S. Geological Survey (USGS) is currently using an integrated approach to investigate two mining impacted watersheds in the western United States (the Animas River in Colorado and the Boulder River in Montana). These studies provide the USDA Forest Service and BLM scientific data for implementing informed land-management decisions regarding cleanup of abandoned mine lands within each watershed. A similar integrated-science approach will be used to characterize the upper Prickly Pear Creek watershed with respect to water and streambed sediment chemistry, aquatic biota, and geologic framework. This integrated database presents data that will be used to identify important pathways of metals movement and biological impacts, thereby guiding resource management decisions of land-managers in several publications that are in preparation.

The use of ultrasound for pregnancy monitoring is critical for the evaluation of hemodynamic parameters essential to fetal viability. In the present study, using B-mode and Doppler ultrasound, we characterized the placenta, subplacenta, maternal, and fetal vessels during normal gestation of healthy agoutis raised in captivity. In total, 30 agoutis were obtained from the Center for the Study and Preservation of Wild Animals, Center of Agricultural Sciences, Federal University of Piauí (Núcleo de Estudos e Preservação de Animais Silvestres-NEPAS, Centro de Ciências Agrárias-CCA, Universidade Federal do Piauí-UFPI). These animals were subjected to B-mode and Doppler ultrasound examinations to evaluate their maternal and fetal hemodynamic profiles. The placenta was located in the mesometrial region and had a discoid, ellipsoid, or globular aspect. With spectral Doppler, characteristic systolic and diastolic flow was observed in the umbilical artery. This flow increased during pregnancy. A cross-sectional view revealed a goblet-shaped placenta. The uteroplacental blood flow was characterized by a marked increase in systolic peak velocity during pregnancy, the presence of a rapid deceleration ramp, and a relatively high diastolic speed. The fetal aortic vascular flow was predominantly systolic and diastolic. The caudal vena cava blood flow was characterized by a systolic peak followed by a decreased diastolic wave throughout pregnancy. In the present study, we characterized the morphologic and hemodynamic interactions of the placenta/subplacenta with maternal and fetal vessels in agoutis at 30, 45, 60, 75, and 90 days gestation using B-mode and Doppler ultrasound. We determined the approximation and separation of the blood flow values of the umbilical artery, subplacental flow, uteroplacental artery, fetal aorta, and fetal vena cava. We believe these values may contribute to an understanding of the gestational biology and aid delivery prediction in this species

Resumen El embarazo está marcado por cambios y adaptaciones cardiovasculares que son importantes para el crecimiento y mantenimiento de la placenta y el feto. Durante este periodo, las adaptaciones vasculares uterinas manifiestan cambios clasificados como de corto o largo plazo los cuales están relacionados con adaptaciones vasodilatadoras, angiogénicas o de remodelación. El estrógeno y los receptores estrogénicos clásicos (REs), RE-α y RE-β, han demostrado ser parcialmente responsables por facilitar el incremento dramático en el fluido sanguíneo uterino necesario durante el embarazo. En ésta revisión bibliográfica se discuten la base estructural para la diversidad y selectividad funcional de los REs por el estrógeno, el papel de los REs sobre los efectos genómicos y no-genómicos en células endoteliales de arterias uterinas (CEAU). Estos temas integran el conocimiento científico sobre la regulación molecular de CEAU para mantener el incremento fisiológico en la perfusión útero-placentaria observada durante un embarazo normal.

Cada vez mais a humanidade, em sua imensa maioria, está alheia às próprias conquistas. A insatisfação com esta realidade tem levado muitos pesquisadores, instituições, empresas e governos a procurar formas alternativas de acompanhar e transmitir todo este acervo científico cultural à sociedade, buscando a melhoria da qualidade da divulgação científica e contribuindo para o processo de cultura e alfabetização científica. Não há tempo nem espaço nos limitados planos curriculares do ensino médio e mesmo nos programas de ensino que propiciem a cultura científica e o acompanhamento do vertiginoso progresso científico e tecnológico atual. Neste sentido, a educação formal escolar precisa ser complementada ou acrescida de uma educação informal, extra-escolar, que possa oferecer à sociedade o que a escola não pode oferecer. A interação do público com museus, feiras de ciências, planetários, exposições científicas e/ou culturais é de grande importância para a aquisição e difusão de conhecimentos relacionados ao mundo científico. Reconhecidamente como um modelo de alfabetização científica esses ambientes promovem uma interação social capaz de propiciar de forma efetiva uma melhor relação ensino-aprendizagem com o público. Partindo desta realidade a Universidade Cruzeiro do Sul e a Escola Municipal de Astronomia (EMA) vêm desenvolvendo um projeto de intervenção no espaço em torno do Planetário do Parque do Ibirapuera com o objetivo de se implantar um ambiente de aprendizagem motivador e desafiador que promova a popularização de conteúdos relacionados à astronomia, astrofísica e cosmologia. Busca-se, também, a aproximação e interação do público com exposições que estão sendo implementadas no planetário. Considerando que se trata de um projeto de mestrado em fase inicial o objetivo do presente trabalho é apresentar a concepção básica e os critérios que estão sendo utilizados do ponto de vista pedag

Courtship behavior of different wild strains of Ceratitis Capitata (Diptera: Tephritidae)
DOE Office of Scientific and Technical Information (OSTI.GOV)
Briceno, D.; Eberhard, W.; Vilardi, J.
This study documents differences in the courtship behavior of wild strains of Ceratitis capitata (Wiedemann) from Madeira (Portugal), Hawaii (U.S.A.), Costa Rica, and Patagonia (Argentina). Some traits showed large variations and others substantial overlaps. The angle at which the male faced toward the female at the moment of transition from continuous wing vibration and intermittent buzzing changed very little during the course of courtship in all strains, but males from Madeira tended to face more directly toward the female than other males. Females tended to look more, and more directly, toward the males as courtship progressed in all strains. Themore » distance between male and female tended to decrease as courtship proceeded in all strains, but the distances at which males initiated continuous vibration, intermittent buzzing, and jumped onto the female were relatively less variable between strains, except for the strain from Costa Rica. Flies of Madeira courted for longer and the male moved his head and buzzed his wings longer than the other strains.

Algunas caracteristicas mostraron grandes variaciones y traslape substancial. Los angulos a los cuales los machos miraron hacia las hembras cambiaron muy poco en el momento de la transicion de la vibracion continua al zumbido intermitente durante el curso del cortejo en todo las cepas, pero los machos de Madeira tendieron a enfrentar mas directamente a la hembra que otros machos. Los angulos de las hembras disminuyeron claramente durante el cortejo en todas las cepas. La distancia entre el macho y la hembra tendio a disminuir conforme el cortejo continuaba en todas las cepas, pero las distancias a las cuales los machos iniciaron la vibracion continua, el zumbido

Successful programs for ex situ and in situ conservation and management of raptors require detailed knowledge about their pathogens. The purpose of this study was to identify the internal parasites of some captive raptors in Mexico, as well as to verify their impact in the health status of infected birds. Birds of prey were confiscated and kept in captivity at the Centro de Investigación y Conservación de Vida Silvestre (CIVS) in Los Reyes La Paz, Mexico State. For this, fecal and blood samples from 74 birds of prey (66 Falconiformes and eight Strigiformes) of 15 species, juveniles and adults from both sexes (39 males and 35 female), were examined for the presence of gastrointestinal and blood parasites. Besides, the oropharyngeal cavity was macroscopically examined for the presence of lesions compatible with trichomoniasis. Among our results we found that lesions compatible with Trichomonas gallinae infection were detected only in two Red-tailed hawks (Buteo jamaicensis) (2.7%); nevertheless, infected birds were in good physical condition. Overall, gastrointestinal parasites were found in 10 (13.5%) raptors: nine falconiforms (13.6%) and one strigiform (12.5%), which mainly presented a single type of gastrointestinal parasite (90%). Eimeria spp. was detected in Harris's hawk (Parabuteo unicinctus), Swainson's hawk (Buteo swainsoni), Red-tailed hawk (B. jamaicensis) and Great horned owl (Bubo virginianus); whereas trematodes eggs were found in Peregrine falcon (Falco peregrinus) and Swainson's hawk (B. swainsoni). Furthermore, eggs of Capillaria spp. were found in one Swainson's hawk (B. swainsoni), which was also infected by trematodes. Hemoprotozoarian were detected in five (6.7%) falconiforms: Haemoproteus spp. in American kestrel (F. sparverius) and Leucocytozoon spp. in Red-tailed hawk (B. jamaicencis). Despite this, no clinical signs referable to gastrointestinal or blood parasite infection were observed in any birds. All parasites identified were recorded

New findings point out that the mechanism of formation of the hernias can be related to the collagenous tissues, under activity of aggressive agents such as the tobacco, alcohol and diabetes. To analyze the collagen present in the cremaster muscle in patients with inguinal hernias, focusing the effect of tobacco, alcohol, and diabetes. Fifteen patients with inguinal hernia divided in three groups were studied: group I (n=5) was control; group II (n=5) were smokers and/or drinkers; and group III (n=5) had diabetes mellitus. All subjects were underwent to surgical repair of the inguinal hernias obeying the same pre, intra and postoperative conditions. During surgery, samples of the cremaster muscle were collected for analysis in polarized light microscopy, collagen morphometry and protein. The area occupied by the connective tissue was higher in groups II and III (p<0.05). The collagen tissue occupied the majority of the samples analyzed in comparison to the area occupied by muscle cells. The content of total protein was higher in groups II and III compared to the control group (p<0.05). The tobacco, alcohol and diabetes cause a remodel the cremaster muscle, leading to a loss of support or structural change in this region, which may enhance the occurrences and damage related to inguinal hernias. Estudos recentes sinalizam que o mecanismo de formação das hérnias pode estar relacionado aos tecidos colagenosos, sob a ação de agentes agressores como o tabaco, o álcool e o diabete. Avaliar o colágeno presente no músculo cremaster em pacientes com hérnias inguinais enfocando o efeito do tabaco, álcool e diabete. Foram estudados 15 pacientes com hérnias inguinais divididos em: grupo I (n=5) controles; grupo II (n=5) indivíduos fumantes e/ou etilistas; e grupo III (n=5) indivíduos que apresentavam diabete melito. Todos foram submetidos à correção cirúrgica das hérnias inguinais obedecendo às mesmas condições pré, intra e pós-operatórias. Durante o

Epidemiology is the study of occurrence, distribution and determinants of health-related events, including the application of that knowledge to the prevention and control of health problems. However, epidemiological studies, in most cases, have limited their research questions to determinants of health outcomes. Research related to the application of knowledge for prevention and control of diseases have been neglected. In this comment, we present a description of how population attributable fraction estimates can provide important elements for planning of prevention and control of diseases in Brazil. RESUMO Epidemiologia é o estudo da ocorrência, distribuição e determinantes de eventos relacionados à saúde da população, incluindo a aplicação desse conhecimento para a prevenção e o controle dos problemas de saúde. Entretanto, estudos epidemiológicos, na maioria das vezes, têm limitado suas perguntas de pesquisa aos fatores determinantes de desfechos em saúde. Pesquisas relacionadas à aplicação do conhecimento para ações de prevenção e controle de doenças têm sido negligenciadas. Nesse comentário, apresentamos uma descrição de como as estimativas de fração atribuível populacional podem fornecer importantes elementos para planejamento de ações de prevenção e controle de doenças no Brasil.

Introducción. La leche materna es esencial para el desarrollo del ser humano, pero puede contener sustancias tóxicas provenientes de la contaminación ambiental, especialmente en las áreas mineras.Objetivo. Determinar la prevalencia de la contaminación con mercurio de la leche materna de mujeres lactantes residentes en los municipios con explotación minera de oro.Materiales y métodos. Se hizo un estudio transversal de 150 madres lactantes de cuatro municipios mineros de Antioquia (El Bagre, Segovia, Remedios y Zaragoza), a quienes se les hizo una encuesta sobre factores sociodemográficos, ocupacionales y ambientales relacionados con el mercurio, y se les tomaron muestras de leche materna, de orina y de cabello. Se calculó el promedio de la concentración de mercurio y las prevalencias municipales de contaminación.Resultados. El promedio de la concentración de mercurio en la leche materna fue de 2,5 (± desviación estándar 9,2) μg/L. La prevalencia de muestras de leche materna con niveles altos de mercurio fue de 11,7 %.Conclusión. En este estudio se evidencia un grave problema en las regiones mineras auríferas de Antioquia por el efecto de la contaminación con mercurio en sectores de la población más vulnerable.

Se conocen tres diferentes fenómenos de gran escala que ocurren en la atmósfera solar, denominados eyecciones coronales de masa (ECMs), protuberancias eruptivas y grandes fulguraciones de dos bandas. Estos fenómenos están estrechamente relacionados y podrían ser distintas manifestaciones de un único proceso físico. Las ECMs son definidas como eyecciones de gran escala de masa y flujo magnético desde la baja corona al espacio interplanetario. Desde su descubrimiento en los '70, muchos modelos han sido propuestos para explicar su origen y evolución. La explicación física de las ECMs es un tema de debate intenso. No obstante, los modelos pueden sintetizarse en dos grandes grupos: 1) los modelos de inyección de flujo y 2) los modelos de almacenamiento y liberación. En este trabajo, se presentan los estudios realizados con una serie de eventos observados con el coronógrafo MICA (Mirror Coronograph for Argentina), el telescopio en H-alfa HASTA (H-alpha Solar Telescope for Argentina) y los coronógrafos C2 y C3 de la sonda SOHO (Solar and Heliospheric Observatory). Los eventos que pudieron ser identificados como ECMs son contrastados dentro del esquema de los dos paradigmas teóricos propuestos.

Este trabalho é parte integrante da pesquisa de mestrado acadêmico em ensino de ciências. Nele, busca-se apresentar os resultados da pesquisa realizada entre os 106 alunos do curso superior de tecnologia em automação industrial do Instituto Federal de Educação, Ciência e Tecnologia de São Paulo campus Cubatão, divididos em cinco turmas, duas no período matutino e três no período noturno. A análise dos resultados deste pré questionárioconstatou a falta de conhecimento básico dos discentes, sobre assuntos relacionados à astronomia, o que pode ser atribuído ao ineficiente processo de aprendizado pelo qual eles passaram tanto no ensino médio como no ensino fundamental, em escolas municipais, estaduais e particulares onde estudaram. No ensino de astronomia, têm-se diagnosticado constantemente diversas dificuldades conceituais tanto por parte de alunos como de professores de todas as áreas e níveis de ensino e poucos de fato a compreendem (ALBRECHT; VOELZKE, 2010). Demonstra-se as duas etapas concluídas do trabalho. A primeira etapa indica a análise dos conhecimentos prévios sobre conceitos astronômicos, através do questionário com 25 perguntas. A fim de corrigir as falhas constatadas, experimentalmente ministrou-se, externo ao conteúdo programático, um curso básico em astronomia, com diferentes estratégias de ensino, tais como, utilização de aulas expositivas dialogadas, recursos audiovisuais e palestras, para corrigir as dificuldades diagnosticadas. Essas estratégias de ensino se comprovaram adequadas às necessidades dos alunos e os conceitos foram finalmente compreendidos. Ao término do curso, completado o interstício de 120 dias, para caracterizar que houve a aprendizagem significativa, realizou-se uma nova pesquisa, quando, exatamente os mesmos 106 alunos responderam as mesmas 25 questões aplicadas na primeira etapa. Constata-se na segunda etapa, após análise, que em todas as questões, houve maior compreensão dos assuntos

Field observations, sampling of mine dumps and mine drainage waters, and laboratory studies of dump materials have been made at mining areas deemed to be on public lands administered by the USDA Forest Service in the Mineral Creek watershed. Results of chemical analyses of dump materials, leachates of those materials, and of surface waters draining mines or dumps provide indications of where acid is generated or consumed, and what metals are mobilized below mines or dumps. Information on 25 sites is reviewed and reclamation priorities are ranked into four classes (high, medium, low priority, or no work required). The western side of the upper Animas watershed (the Mineral Creek watershed) has a history of mining and prospecting for about 130 years. The intensity of miningrelated disturbance is higher than in most parts of the San Juan Mountains region, but actually is much less than the eastern half of the watershed (US BLM lands) and none of the mines moved millions of tons of rock and ore as in some of the eastern mines. The majority of the roughly one thousand mining sites on the USFS lands are very small (less than 100 tons or 70 cubic yards of dump material), are more than 2 miles from a major stream, or are so inaccessible as to prohibit reclamation. Twenty five sites have been considered by others to have significant size and potential for significant environmental degradation. These most significant mining areas were evaluated by multiple criteria, including tendency to generate acid or liberate toxic metals, observed acidic pH or dead vegetation (?kill zones?) below dumps or adits, potential mobility of metals, and likelihood of transport into streams of the watershed. In the author?s opinion, no single measurable parameter, such as metal concentration, is reliable for ranking significance or feasibility of reclamation. Rather, subjective estimates are required to evaluate combinations of, or interactions among, several parameters. The most subjective

Daily precipitation and maximum and minimum temperature time series from a regional climate model (RegCM2) configured using the continental United States as a domain and run on a 52-km (approximately) spatial resolution were used as input to a distributed hydrologic model for one rainfall-dominated basin (Alapaha River at Statenville, Georgia) and three snowmelt-dominated basins (Animas River at Durango. Colorado; east fork of the Carson River near Gardnerville, Nevada: and Cle Elum River near Roslyn, Washington). For comparison purposes, spatially averaged daily datasets of precipitation and maximum and minimum temperature were developed from measured data for each basin. These datasets included precipitation and temperature data for all stations (hereafter, All-Sta) located within the area of the RegCM2 output used for each basin, but excluded station data used to calibrate the hydrologic model. Both the RegCM2 output and All-Sta data capture the gross aspects of the seasonal cycles of precipitation and temperature. However, in all four basins, the RegCM2- and All-Sta-based simulations of runoff show little skill on a daily basis [Nash-Sutcliffe (NS) values range from 0.05 to 0.37 for RegCM2 and -0.08 to 0.65 for All-Sta]. When the precipitation and temperature biases are corrected in the RegCM2 output and All-Sta data (Bias-RegCM2 and Bias-All, respectively) the accuracy of the daily runoff simulations improve dramatically for the snowmelt-dominated basins (NS values range from 0.41 to 0.66 for RegCM2 and 0.60 to 0.76 for All-Sta). In the rainfall-dominated basin, runoff simulations based on the Bias-RegCM2 output show no skill (NS value of 0.09) whereas Bias-All simulated runoff improves (NS value improved from - 0.08 to 0.72). These results indicate that measured data at the coarse resolution of the RegCM2 output can be made appropriate for basin-scale modeling through bias correction (essentially a magnitude correction). However, RegCM2 output, even when bias

It is commonly thought that Aristotle's aether, an unusual sort of matter filling the heavens, has been shown to be superfluous or even impossible by the advances of modern science. However, this opinion is questionable, and the Aristotelian doctrine is at root not trivial. This dissertation critically examines Aristotle's arguments for the existence of aether, first explaining how these arguments should be taken, and then supplementing them with the implications of his doctrine on light and recent developments in modern science. The first part of the dissertation is subdivided two sections, one on aether, the other on void. The first section is a careful study of the arguments for aether in De Caelo I.2, manifesting that each assumes at least one questionable premise. But the ultimate foundation of the doctrine of aether is not principally in De Caelo I.2; rather, it lies in the refutation of void in Physics IV.6-9. Accordingly, the second section examines and defends certain of the arguments against void, arguing that one who postulates void must maintain a number of physical impossibilities. This section concludes with a consideration of additional argument against void-implicit in Aristotle's metaphysics-proceeding from the nature of accidents. On this reading of the arguments against void the resulting conclusion is that the heavens must be filled with some kind of substance, but not that this substance must be of an unusual nature. To supplement this imperfection in the natural-philosophic argument, there follows the second part of the dissertation, showing a significant compatibility between Aristotle's general idea of aether and the findings of contemporary physics. First, I summarize Aristotle's account of light and the transparent medium in De Anima II.7 and De Sensu et Sensato 3, and their relation to aether. Then I look to twentieth-century treatments of light and energy, arguing that they suggests three candidates for a modern day ``aether'': first

to develop and validate a scale to evaluate nursing attitudes in relation to hospitality for the humanization of nursing care. Participants: the sample consisted of 499 nursing professionals and undergraduate students of the final two years of the Bachelor of Science in Nursing program. the instrument has been developed and validated to evaluate the ethical values related to hospitality using a methodological approach. Subsequently, a model was developed to measure the dimensions forming the construct hospitality. the Axiological Hospitality Scale showed a high internal consistency, with Cronbach's Alpha=0.901. The validation of the measuring instrument was performed using factorial, exploratory and confirmatory analysis techniques with high goodness of fit measures. the developed instrument showed an adequate validity and a high internal consistency. Based on the consistency of its psychometric properties, it is possible to affirm that the scale provides a reliable measurement of the hospitality. It was also possible to determine the dimensions or sources that embrace it: respect, responsibility, quality and transpersonal care. desenvolver e validar uma escala que permita avaliar a atitude dos enfermeiros em termos de hospitalidade, visando a humanização da enfermagem.Participantes: a amostra foi constituída por 499 profissionais e estudantes de enfermagem dos dois últimos anos do curso de graduação em Enfermagem. utilizando-seuma abordagem metodológica, foi desenvolvido e validado um instrumento para avaliar os valores éticos relacionados com a hospitalidade.

to analyze the effects of work on the health of nurses who work in clinical surgery departments at university hospitals in relation to physical, social and psychological suffering and pain. a quantitative transversal study was carried out between 2012 and 2013 in four institutions in a state located in the south of Brazil. We studied 65 nurses who responded to questions on their habits. We also obtained sociodemographical information on them as well as conducting an evaluation on work relational damage using an evaluation scale. Associations were checked through the use of the Chi-Sqaure and Fisher's exact test. Correlations were checked using the Spearmann test. we found that physical ailments persisted and that there were connections between social and psychological pain/suffering and variable physical activities as well as connections with accidents in the work place and the option to work shifts. We noted correlations between social and psychological pain/suffering. nurses had their health compromised due to their work in clinical surgery departments. analisar os efeitos do trabalho na saúde de enfermeiros que atuam em clínicas cirúrgicas de hospitais universitários, relacionando-os aos danos físicos, sociais e psicológicos. estudo quantitativo, transversal, realizado entre 2012 e 2013 em quatro instituições de um Estado da região sul do Brasil.

Introducción: la infertilidad es un problema global en aumento. Se estima que aproximadamente un 15% de las parejas en edad reproductiva tiene dificultades a la hora de concebir. De estas, alrededor de la mitad presentan uno o varios factores masculinos asociados a infertilidad o subfertilidad, aislados o en combinación con problemas de origen femenino. Durante la última década se ha empezado a estudiar la infertilidad desde una perspectiva multifactorial, considerando las interacciones y conexiones entre diferentes situaciones genéticas, epigenéticas, bioquímicas y fisiológicas del paciente.Objetivo: la presente revisión pretende describir mecanismos epigenéticos que pueden ser modulados mediante aspectos nutricionales y que están relacionados con la etiología de la infertilidad masculina y con la herencia transgeneracional de este fenotipo.Material y métodos: se ha realizado una extensa búsqueda de publicaciones científicas en las principales bases de datos electrónicas especializadas: NBCI, Elsevier, Scielo, Scirus y Science Direct.Resultados y conclusión: varios trabajos que muestran la importancia del estado nutricional en la fertilidad del hombre y, más específicamente, la capacidad de los componentes de la dieta para modificar los perfiles epigenéticos que no únicamente pueden afectar a su fertilidad, sino que también pueden ser transmitidos a la descendencia mediante lo que se ha denominado herencia transgeneracional, ocasionándoles problemas de salud diversos entre los que también se hallan problemas en la fertilidad.

Resumen El estudio de la problemática relacionada con la infección de tuberculosis (TB) en la frontera México-Estadounidense implica la consideración de tres aspectos complejos y entrelazados: la TB, una entidad patológica que debido a sus características epidemiológicas y patogénicas, resulta difícil de seguir y atender de manera completa; la zona fronteriza, zona geográfica y epidemiológica que entrelaza dos naciones, dos culturas, dos sistemas de salud y leyes diferentes; además del estigma, que implica más que tratamientos clínicos y abordajes de categorías de riesgo debido a la condición social y bajo conocimiento. Este trabajo narra diez estrategias realizadas en México y la frontera México-Estadounidense del año 2006 al 2013 como un esfuerzo de ampliar la comprensión de este fenómeno social y de salud pública conformado por una infección, un entorno físico y personas, también de la identificación y aplicación de prácticas competentes de abogacía y movilización social. Los trabajos realizados y presentados dan a conocer diferentes intervenciones para generar adherencia al tratamiento, mitigar el estigma relacionado con la infección de TB, mejorar la atención centrada en la persona e informar la relevancia del abordaje micro y macro de la salud y el trabajador social.

To analyze whether an increase in patient severity and nursing workload are correlated to a greater incidence of adverse events (AEs) in critical patients. A prospective single cohort study was performed on a sample of 138 patients hospitalized in an intensive care unit (ICU). A total of 166 AEs, occurred, affecting 50.7% of the patients. Increased patient severity presented a direct relationship to the probability of AEs occurring. However, nursing workload did not present a statistically significant relationship with the occurrence of AEs. The results cast light on the importance of using evaluation tools by the nursing personnel in order to optimize their daily activities and focus on patient safety. Analisar se o aumento da gravidade do paciente e a carga de trabalho de enfermagem está relacionado à maior incidência de Eventos Adversos (EAs) em pacientes críticos. Estudo de coorte única, prospectivo, com amostra de 138 pacientes internados em uma Unidade de Terapia Intensiva (UTI). Ao todo, foram evidenciados 166 EAs, que acometeram 50,7% dos pacientes. O aumento da gravidade do paciente apresentou relação direta com a chance de ocorrência de EAs. Entretanto, a carga de trabalho de enfermagem não apresentou relação estatisticamente significativa, na ocorrência de EAs. Os resultados permitem refletir acerca da importância da equipe de enfermagem, em utilizar instrumentos de avaliação, com o objetivo de melhorar e planejar suas ações diárias, com foco na segurança do paciente.

Através de simulações numéricas buscamos quantificar os efeitos que o binarismo não resolvido causa na determinação da função de massa (MF) de aglomerados estelares. Geramos diagramas cor-magnitude (CMDs) artificiais simulando uma população única, caracterizada por estrelas de mesma idade e composição quí mica, com uma fração de binárias não resolvidas e distribuição em massa das estrelas dada por uma MF do tipo lei de potência. A presença de pares de estrelas não resolvidos faz com que a MF obtida da função de luminosidade (LF) tenha a têndencia de ser mais plana do que a MF que gerou o CMD artificial. Propomos um tratamento de correção para tal efeito. Outro efeito relacionado diz respeito ao alargamento do CMD, que apresenta-se como um indicador do número total de estrelas no domí nio de baixas massas (m < 0.6M¤). Todos os resultados acima possuem uma forte dependência com os erros fotométricos e estão baseados na hipótese de que ambas estrelas do par não resolvido são sorteadas de uma mesma MF de forma independente. O objetivo final é aplicarmos o tratamento aqui desenvolvido para implementarmos a análise da nossa amostra de aglomerados ricos da Grande Nuvem de Magalhães.

Acidic, metal-rich waters produced by the oxidative weathering and resulting leaching of major and trace elements from pyritic rocks can adversely affect water quality in receiving streams and riparian ecosystems. Five study areas in the southern Rocky Mountains with naturally acidic waters associated with porphyry mineralization were studied to document variations in water chemistry and processes that control the chemical variations. Study areas include the Upper Animas River watershed, East Alpine Gulch, Mount Emmons, and Handcart Gulch in Colorado and the Red River in New Mexico. Although host-rock lithologies in all these areas range from Precambrian gneisses to Cretaceous sedimentary units to Tertiary volcanic complexes, the mineralization is Tertiary in age and associated with intermediate to felsic composition, porphyritic plutons. Pyrite is ubiquitous, ranging from ???1 to >5 vol.%. Springs and headwater streams have pH values as low as 2.6, SO4 up to 3700 mg/L and high dissolved metal concentrations (for example: Fe up to 400 mg/L; Cu up to 3.5 mg/L; and Zn up to 14.4 mg/L). Intensity of hydrothermal alteration and presence of sulfides are the primary controls of water chemistry of these naturally acidic waters. Subbasins underlain by intensely hydrothermally altered lithologies are poorly vegetated and quite susceptible to storm-induced surface runoff. Within the Red River study area, results from a storm runoff study documented downstream changes in river chemistry: pH decreased from 7.80 to 4.83, alkalinity decreased from 49.4 to <1 mg/L, SO4 increased from 162 to 314 mg/L, dissolved Fe increased from to 0.011 to 0.596 mg/L, and dissolved Zn increased from 0.056 to 0.607 mg/L. Compared to mine drainage in the same study areas, the chemistry of naturally acidic waters tends to overlap but not reach the extreme concentrations of metals and acidity as some mine waters. The chemistry of waters draining these mineralized but unmined areas can be used to

A 3D gravity model of the Copper Flat Mine was performed as part of the exploration of new resources in at the mine. The project is located in the Las Animas Mining District in Sierra County, New Mexico. The mine has been producing ore since 1877 and is currently owned by the New Mexico Copper Corporation, which plans o bringing the closed copper mine back into production with innovation and a sustainable approach to mining development. The Project is located on the Eastern side of the Arizona-Sonora-New Mexico porphyry copper Belt of Cretaceous age. Copper Flat is predominantly a Cretaceous age stratovolcano composed mostly of quartz monzonite. The quartz monzonite was intruded by a block of andesite alter which a series of latite dikes creating veining along the topography where the majority of the deposit. The Copper Flat deposit is mineralized along a breccia pipe where the breccia is the result of auto-brecciation due to the pore pressure. There have been a number of geophysical studies conducted at the site. The most recent survey was a gravity profile on the area. The purpose of the new study is the reinterpretation of the IP Survey and emphasizes the practical use of the gravity geophysical method in evaluating the validity of the previous survey results. The primary method used to identify the deposit is gravity in which four Talwani models were created in order to created a 3D model of the ore body. The Talwani models have numerical integration approaches that were used to divide every model into polygons. The profiles were sectioned into polygons; each polygon was assigning a specific density depending on the body being drawn. Three different gridding techniques with three different filtering methods were used producing ten maps prior to the modeling, these maps were created to establish the best map to fit the models. The calculation of the polygons used an exact formula instead of the numerical integration of the profile made with a Talwani approach. A

The San Juan sag, concealed by the vast San Juan volcanic field of south-central Colorado, has only recently benefited from oil and gas wildcat drilling and evaluations. Sound geochemical analyses and maturation modeling are essential elements for successful exploration and development. Oil has been produced in minor quantities from an Oligocene sill in the Mancos Shale within the sag, and major oil and gas production occurs from stratigraphically equivalent rocks in the San Juan basin to the south-west and in the Denver basin to the northeast. The objectives of this study were to identify potential source rocks, assess thermal maturity, and determine hydrocarbon-source bed relationships. Source rocks are present in the San Juan sag in the upper and lower Mancos Shale (including the Niobrara Member), which consists of about 666 m (2184 ft) of marine shale with from 0.5 to 3.1 wt. % organic carbon. Pyrolysis yields (S1 + S2 = 2000-6000 ppm) and solvent extraction yields (1000-4000 ppm) indicate that some intervals within the Mancos Shale are good potential source rocks for oil, containing type II organic matter, according to Rock-Eval pyrolysis assay. Oils produced from the San Juan sag and adjacent part of the San Juan basin are geochemically similar to rock extracts obtained from these potential source rock intervals. Based on reconstruction of the geologic history of the basin integrated with models of organic maturation, we conclude that most of the source rock maturation occurred in the Oligocene and Miocene. Little to no maturation took place during Laramide subsidence of the basin, when the Animas and Blanco Basin formations were deposited. The timing of maturation is unlike that of most Laramide basins in the Rocky Mountain region, where maturation occurred as a result of Paleocene and Eocene basin fill. The present geothermal gradient in the San Juan sag is slightly higher (average 3.5??C/100 m; 1.9??F/100 ft) than the regional average for southern Rocky

learning of astronomy in basic education. Embora a astronomia seja considerada uma das ciências mais antigas da humanidade e ainda que a compreensão de seus conceitos tenha trazido enormes avanços para a Ciência e, consequentemente, para a sociedade, observa-se que uma parcela significativa de pessoas encontra-se à margem desses conhecimentos. De acordo com os Parâmetros Curriculares Nacionais para a Educação Básica, cabe à escola a difusão dos conceitos cientificamente corretos, entre eles os relacionados à área de astronomia. Pertinente a essa questão, apresenta-se uma pesquisa realizada com 140 estudantes do nono ano do ensino fundamental e com 120 estudantes da terceira série do ensino médio de quatro escolas da região de Passo Fundo/RS. Buscou-se averiguar, por meio de um questionário composto de questões abertas e de múltipla escolha, o conhecimento desse grupo de estudantes acerca de termos e fenômenos astronômicos básicos e, também, verificar se o índice de acertos cresce à medida que eles avançam nas diferentes e gradativas séries dos ensinos fundamental e médio. De modo geral, os resultados apresentados demonstram que o ensino de astronomia na educação básica enfrenta deficiências. Das 20 questões investigadas, em 17 os índices de acertos são semelhantes nas respostas dadas por estudantes de nível fundamental e médio, revelando que muitas concepções equivocadas permanecem ao longo da educação básica. Isso evidencia que tais temas não são - ou são pouco - abordados durante esses dois níveis de escolarização. Assim, conclui-se que a discussão dos conceitos relacionados com a astronomia deve receber maior ênfase na abordagem dos diferentes conteúdos, sendo necessária uma ação nacional em prol do seu ensino. Acredita-se que essa ação nacional deve estar apoiada em um pilar triplo de atores coletivos: comunidade científica, comunidade astronômica semiprofissional e comunidade escolar. Por fim, esse pilar seria

Los procesos de fotoionización son de una importancia fundamental [1] y encuentran aplicación en un gran número de contextos científicos: Astrofísica [2], química de las radiaciones, biología. Los investigadores de dichos campos, necesitan de valores de fiables de secciones eficaces para la fotoionización parcial, la Fotoabsorción, así como para los procesos de fotofragmentación en amplios intervalos espectrales, particularmente en estudios de modelización [3-5]. En este trabajo se ha centrado la atención sobre el oxido nítrico, que se ha considerado apropiado y relevante por varios motivos: por el trascendental papel que representa en la física y química de la alta atmosfera [6], aparte de por estar íntimamente relacionado con los problemas de contaminación. Los procesos de recombinación disociativa [7] del NO, donde los estados Rydberg se encuentran directamente implicados, son relevantes, por ejemplo, en las regiones E y F de la ionosfera [7]. En este trabajo se estudia la fotoionización del NO desde el estado fundamental con la versión molecular del método del orbital de defecto cuántico (MQDO). Para ello se calcula el diferencial de las fuerzas de oscilador parciales que constituyen los canales de fotoionización del NO desde el estado fundamental. La continuidad del diferencial de fuerza de oscilador calculada a través del umbral de fotoionización, esto es, en las regiones del espectro discreta y del continua, se adopta como criterio de calidad la escasez de datos comparativos [8].

Primary graft dysfunction is a multifactorial syndrome with great impact on liver transplantation outcomes. This review article was based on studies published between January 1980 and June 2015 and retrieved from PubMed database using the following search terms: "primary graft dysfunction", "early allograft dysfunction", "primary non-function" and "liver transplantation". Graft dysfunction describes different grades of graft ischemia-reperfusion injury and can manifest as early allograft dysfunction or primary graft non-function, its most severe form. Donor-, surgery- and recipient-related factors have been associated with this syndrome. Primary graft dysfunction definition, diagnostic criteria and risk factors differ between studies. RESUMO A disfunção primária do enxerto hepático é uma síndrome multifatorial com grande impacto no resultado do transplante de fígado. Foi realizada uma ampla revisão da literatura, consultando a base de dados PubMed, em busca de estudos publicados entre janeiro de 1980 e junho de 2015. Os termos descritivos utilizados foram: "primary graft dysfunction", "early allograft dysfunction", "primary non-function" e "liver transplantation". A disfunção traduz graus diferentes da lesão de isquemia e reperfusão do órgão, e pode se manifestar como disfunção precoce ou, na forma mais grave, pelo não funcionamento primário do enxerto. Fatores relacionados ao doador, ao transplante e ao receptor contribuem para essa síndrome. Existem definições diferentes na literatura quanto ao diagnóstico e aos fatores de risco associados à disfunção primária.

Este trabalho visa analisar a possibilidade de relacionar conteúdos aplicados no ensino fundamental e médio de forma interdisciplinar por intermédio da astronomia, com a intervenção de objetos de aprendizagem que possam integrar as disciplinas e a utilização de recursos tecnológicos. Em uma pesquisa prévia com 20 professores de uma escola estadual situada na cidade de Guarulhos foi observado que apenas 25% dos professores utilizam algum recurso tecnológico para o desenvolvimento de conteúdos pertinentes à sua disciplina, tais como sites e softwares educativos, sendo que a maioria absoluta continua ensinando apenas com livros didáticos. A maior parte dos professores apresenta dificuldades em trabalhar sua disciplina de forma interdisciplinar, ou seja, 75% dos professores preferem aplicar os conteúdos seguindo uma hierarquia linear de tópicos, evitando a discussão de temas que de alguma forma estão relacionados. A astronomia pode vir à fascinar o ser humano e despertar sua curiosidade promovendo um maior interesse no aprendizado, podendo favorecer análises interdisciplinares de forma lógica e objetiva, desta forma colocar a astronomia como tema motivador interdisciplinar, pode ser relevante no que se refere ao distanciamento da fragmentação dos conteúdos. No Estado de São Paulo, a implantação da proposta curricular no ensino fundamental e médio mostra claramente a inserção da astronomia na maior parte das séries, principalmente na 6ª série em que todo o bimestre se fala de astronomia.

hepatite e hepatocarcinoma. A relação desta hepatopatia e a obesidade já é bem conhecida; porém, é possível que alguns parâmetros das comorbidades estejam mais relacionados do que outros na fisiopatogenia da doença. Correlacionar a doença hepática gordurosa não alcoólica (DHGNA) com as comorbidades da síndrome metabólica em pacientes obesos mórbidos em pré-operatório de cirurgia bariátrica. Avaliação ultrassonográfica e laboratorial de pacientes obesos em pré-operatório para cirurgia bariátrica. Durante o preparo para a operação em todos os pacientes foi avaliada DHGNA através de ultrassonografia. De acordo com o resultado, os pacientes foram separados em dois grupos: sem DHGNA e com DHGNA. Para análise entre os grupos, avaliaram-se as seguintes variáveis clínicas e laboratoriais: insulina, HOMA-IR, hemoglobina glicada, colesterol total e frações, triglicerídeos, transaminase pirúvica, transaminase glutâmico oxalacética, gama glutamil transferase, proteína C reativa, albumina, ferritina. Os pacientes que relataram uso de bebida alcoólica ou que apresentaram hepatite foram excluídos do estudo. Avaliou-se um total de 82 pacientes (74 mulheres e 8 homens), sendo 53 (64.6%) com DHGNA e 29 (35.4%) sem. Os níveis de hemoglobina glicada (p=0.05) e de LDL (p=0.01) mostraram-se mais relacionados no grupo de pacientes com DHGNA. A hemoglobina glicada e o LDL tiveram relação com a presença de DHGA.

utilizou os registros das orientações realizadas pelo farmacêutico clínico na unidade de internação do Serviço de Transplante Renal e Hepático, Hospital Universitário Walter Cantídio, em Fortaleza (CE), de janeiro a julho de 2014. Foram analisadas, de acordo com sua significância e desfechos clínicos obtidos, as seguintes variáveis registradas no Banco de Dados do Serviço de Farmácia Clínica: orientações farmacêuticas na alta, problemas e resultados negativos relacionados aos medicamentos, e intervenções farmacêuticas realizadas. A primeira alta pós-transplante envolveu toda a equipe multiprofissional, sendo o farmacêutico responsável pela orientação do tratamento medicamentoso. A média de altas/mês com orientação farmacêutica no período do estudo foi de 10,6±1,3, totalizando 74 orientações. O tratamento clínico prescrito teve média de 9,1±2,7 medicamentos por paciente. Foram identificados 59 problemas relacionados aos medicamentos; 67,8% relacionaram-se com a não prescrição do medicamento necessário, acarretando 89,8% de risco de resultados negativos associados aos medicamentos por problema de saúde não tratado. A principal intervenção foi a solicitação de inclusão do medicamento (66,1%), e 49,2% dos medicamentos envolvidos agiam no aparelho digestivo/metabolismo. Todas as intervenções foram classificadas como apropriadas, e 86,4% foram capazes de prevenir o resultado negativo. A orientação do farmacêutico clínico junto à equipe multiprofissional no momento da alta do paciente transplantado é importante, pois previne resultados negativos associados à farmacoterapia, garantindo a conciliação medicamentosa e a segurança do paciente.

principal objetivo desta tese de doutoramento foi desenvolver um modelo para otimizar o desenho e operacao de sistemas de GD para o setor da construcao de edificios comerciais em Portugal, considerando os respetivos Impactes de Ciclo de Vida (IAVC) e Custos de Ciclo de Vida (CCV), de modo a satisfazer as necessidades energeticas do edificio. Tres tipos de tecnologias de cogeracao (Micro-Turbinas, Motores de combustao interna, e Celulas combustiveis de Oxido solido), e dois tipos de tecnologias de energia solar, solar termica e fotovoltaica, constituem os sistemas de GD que sao acoplados aos sistemas convencionais. Foi desenvolvido um modelo de CV, tendo em conta todos os impactes relacionados com a construcao e operacao dos sistemas de energia, bem como os processos a montante relacionados com a producao do GN. Em particular, o mix de GN consumido em Portugal em 2011 foi identificado (60% da Nigeria, 40% da Argelia) e os impactes relativos a cada uma das vias de abastecimento foram avaliados separadamente para quatro categorias de impacte ambiental: Consumo de Energia Primaria (CEP), Gases com Efeito de Estufa (GEE), acidificacao, e eutrofizacao. Devido a importancia das emissoes de GEE na formulacao de politicas, foi tambem realizada uma analise de incerteza as emissoes de GEE do GN fornecido a Portugal. Foi desenvolvido um modelo matematico, em linguagem de Programacao General Algebraic Modeling System (GAMS), que utiliza os resultados da ACV dos sistemas de energia e as suas implicacoes economicas para minimizar o CCV e IACV ao longo de um horizonte de planeamento definido pelo decisor. Foram derivadas fronteiras otimas de Pareto, representando as relacoes entre o tipo de IACV (CEP, GEE, acidificacao, eutrofizacao) e CCV decorrentes da satisfacao das necessidades energeticas do edificio. Para aumentar a robustez do modelo, dada a incerteza dos precos dos combustiveis (GN e eletricidade), foi desenvolvido um modelo de custos robusto para os sistemas de GD, que e menos

Traveltime and gains and losses within a stream are important basic characteristics of streamflow. The lower Purgatoire River flows more than 160 river miles from Trinidad to the Arkansas River near Las Animas. A better knowledge of streamflow traveltime and streamflow gains and losses along the lower Purgatoire River would enable more informed management decisions about the availability of water supplies for irrigation use in southeastern Colorado. In 1994-95, the U.S.\\x11Geological Survey, in cooperation with the Purgatoire River Water Conservancy District and the Arkansas River Compact Administration, evaluated streamflow traveltime and estimated streamflow gains and losses using historical surface-water records. Traveltime analyses were used along the lower Purgatoire River to determine when streamflows would arrive at selected downstream sites. The substantial effects of diversions for irrigation and unmeasured return flows in the most upstream reach of the river prevented the tracking of streamflow through reach\\x111. Therefore, the estimation of streamflow traveltime for the 60.6 miles of river downstream from Trinidad could not be made.Hourly streamflow data from 1990 through 1994 were used to estimate traveltimes of more than 30 streamflow events for about 100 miles of the lower Purgatoire River. In the middle reach of the river, the traveltime of streamflow for the 40.1\\x11miles ranged from about 11 to about 47\\x11hours, and in the lower reach of the river, traveltime for the 58.5 miles ranged from about 6 to about 61 hours.Traveltime in the river reaches generally increased as streamflow decreased, but also varied for a specific streamflow in both reaches. Streamflow gains and losses were estimated using daily streamflow data at the upstream and downstream sites, available tributary inflow data, and daily diversion data. Differences between surface-water inflows and surface-water outflows in a reach determined the quantity of water gained or lost. In

Maize x Teosinte Hybrid Cobs Do Not Prevent Crop Gene Introgression. Whether introgression from crops to wild relatives can occur is an important component of transgene risk assessment. In the case of maize, which co-occurs with its wild relative teosinte in Mexico, the possibility of introgression has been controversial. Maize is cross-compatible with teosinte, and spontaneous hybridization is known to occur. Some scientists have hypothesized that the maize x teosinte cob infructescence will prevent progeny dispersal, thus preventing introgression. Motivated by a prior study where we found maize x teosinte hybrid fruits naturally dispersed under field conditions, we tested whether hybrid cobs hold their fruits as tightly as maize cobs. We found the force required to detach hybrid fruits was substantially and significantly less than that for maize. Consequently, we expect that introgression of transgenes from maize into teosinte in Mexico should occur largely unimpeded by the hybrid cob.La mazorca o elote híbrido de maíz x teocintle no impide la introgresión de genes transgénicos provenientes del cultivo. La introgresión entre el maíz cultivado y el maíz silvestre, o teocintle, es un componente importante en la evaluación ambiental relacionada con los riesgos de la introducción de genes transgénicos. La posibilidad de introgresión entre el maíz domesticado y el teocintle ha sido un tema controversial, en particular en México, donde maíz y teocintle coexisten. El maíz es compatible con el teocintle y la hibridización espontánea ocurre entre ellos. Algunos científicos han planteado como hipótesis que al cruzar el maíz con teocintle, la estructura interna de la infrutescencia que sujeta los frutos conocida como la mazorca de maíz o el elote, impide la dispersión de la progenie evitando que la introgresión ocurra. Los resultados de un estudio previo evidencian la dispersión de los frutos híbridos del maíz x teocintle en condiciones naturales

RESUMEN La comunicación sobre sexualidad entre padres/madres y adolescentes enfrenta dificultades particulares producto de factores socioculturales. Este estudio tuvo como objetivo documentar las actitudes de padres/madres y adolescentes hacia la comunicación sobre temas de sexualidad. Los resultados emanan de la medición inicial del Proyecto Cuídalos. Los datos de este estudio forman parte de un estudio amplio que evaluó un módulo interactivo basado en la web para mejorar comunicación sobre temas de salud entre padres/madres y adolescentes entre 13–17 años. En este artículo, reportamos datos basales que contestaron los/as participantes sobre comodidad al hablar sobre temas de salud sexual. La muestra, de los datos aquí expuestos, estuvo compuesta por 458 diadas de madres/padres y sus hijos/as adolescentes (n=916). Se realizó análisis de frecuencias y medidas de tendencia central con los datos obtenidos inicialmente. La edad promedio de los adolescentes fue de 15 años, de los que un 15% se encontraban activos sexualmente. Los/as adolescentes tienen mejor disposición que los/as padres/madres para hablar sobre sexualidad. Sin embargo, los/as padres/madres entienden que comparten suficiente información sobre temas relacionados a la sexualidad. Los/as padres/madres y adolescentes reportaron algún grado de dificultad e incomodidad al hablar sobre métodos específicos de prevención. Los resultados destacan la necesidad de incorporar a los/as padres/madres en intervenciones con adolescentes sobre temas de salud sexual. En Puerto Rico es necesario desarrollar programas dirigidos a minimizar las conductas sexuales de alto riesgo en jóvenes. PMID:28736599

En los primeros años de la pasada década, un grupo de Astrónomos de La Plata iniciaron trabajos de investigación en Geodesia Satelital. En esta presentación se propone repasar sus principales logros y situarlos en el contexto del desarrollo de la disciplina a nivel mundial. Por entonces las aplicaciones prácticas de la disciplina eran indirectas y solo evidentes para los especialistas. Los errores del Posicionamiento Satelital eran de varios metros y en posicionamiento relativo, del orden de medio metro. Estos resultados se lograban al cabo de varios días de medición continuada. En los años siguientes, el sistema GPS alcanzó su nivel operacional y produjo una revolución tanto en lo relacionado con los tiempos de medición como con las precisiones. El grupo de La Plata se desarrolló simultáneamente con GPS, lo que posibilitó su participación actual en diversos temas vigentes: aplicaciones de alta precisión para la materialización de sistemas terrestres de referencia, monitoreo de movimientos de la corteza, contribución con servicios internacionales para la determinación de movimientos tectónicos globales y regionales, monitoreo de la ionósfera a partir de la propagación de las señales, determinación de la ondulación del geoide a escala local, etc. También se generaron muchas aplicaciones prácticas algunas en tiempo real: navegación, apoyo a imágenes aéreas o satelitales, aplicaciones a la agricultura, catastro y ordenamiento territorial, apoyo a relevamientos geofísicos, etc.

Em 2002 o ensino de Astronomia foi proposto como um dos temas estruturadores pelos Parâmetros Curriculares Nacionais e sugerido como facilitador para que o aluno compreendesse a Física como construção humana e parte do seu mundo vivencial, mas raramente seus conceitos foram ensinados. A presente pesquisa discute dois aspectos relacionados à abordagem de Astronomia. O primeiro aspecto é se ela está sendo abordada pelos professores do Ensino Médio e o segundo, aborda a maneira como ela está sendo ensinada. Optou-se pela aplicação de um questionário a partir do 2° semestre de 2006 e durante o ano de 2007 com professores que ministram a disciplina de Física, os quais trabalham em escolas estaduais em Rio Grande da Serra, Ribeirão Pires e Mauá no estado São Paulo. Dos 66,2% dos professores que responderam ao questionário nos municípios de Rio Grande da Serra, Ribeirão Pires e Mauá, 57,4% não aplicaram nenhum tópico de astronomia, 70,2% não utilizaram laboratório, 89,4% não utilizaram qualquer tipo de programa computacional, 83,0% nunca fizeram visitas com alunos a museus e planetários e 38,3% não indicaram qualquer tipo de livro ou revista referente à astronomia aos seus alunos. Mesmo considerando a Astronomia um conteúdo potencialmente significativo, esta não fez parte dos planejamentos escolares. Portanto são necessárias propostas que visem estratégias para a educação continuada dos professores como, por exemplo, cursos específicos sobre o ensino em Astronomia.

Resumen El VIH es un problema de salud importante dentro de la comunidad latina de los Estados Unidos. Gracias a los esfuerzos de prevención, los niveles de contagio entre los latinos se han mantenido estables por más de una década. Sin embargo, esta población sigue siendo afectada a niveles muy altos, en particular entre hombres que tienen sexo con hombres (HSH), de origen latino y que hablan principalmente el idioma español. Existen varios factores que contribuyen a la transmisión del VIH entre esta población, como son: el uso de drogas; la violencia dentro de la pareja; la presencia de infecciones de transmisión sexual; relaciones sexuales sin protección, dentro y fuera de la pareja; el evadir la búsqueda de recursos (prueba y tratamiento adecuado) por temor a ser discriminado o por su estatus migratorio; la escasez de recursos económicos o estado de pobreza y los patrones relacionados a la migración. En particular, Investigaciones Epidemiológicas de Comportamientos han determinado: cómo algunas dinámicas en parejas están directamente asociadas a los comportamientos sexuales de riesgos. En consecuencia, es necesaria mayor investigación para identificar esas dinámicas, y a su vez, realizar intervenciones dirigidas a la reducción de conductas de riesgo enfocadas en parejas de hombres del mismo sexo. En este escrito, se describe la importancia del uso de las relaciones de pareja como estrategia en la reducción de la trasmisión del VIH/SIDA en HSH de origen latino y que hablan principalmente el idioma español en los Estados Unidos.

Resumo Contexto Úlceras são a resultante final de varizes associadas a refluxo de veias safenas. Objetivo Demonstrar a possibilidade de associar dois procedimentos, a escleroterapia com espuma de veias safenas e o enxerto de pele parcial, para o tratamento de pacientes com úlceras venosas relacionadas a refluxo de veias safenas. Métodos Foram tratados 20 membros em 20 pacientes, todos com ulcerações relacionadas a refluxo de veias safenas. Realizamos o enxerto de pele expandida, seguido da escleroterapia ecoguiada com espuma de polidocanol nas veias associadas às úlceras, através de punção ou dissecção da veia. Resultados Em todos os casos, houve melhora dos sintomas relacionados à úlcera e cicatrização da lesão. Em 11 casos, obtivemos a viabilidade do enxerto de pele por completo; em quatro casos, houve cicatrização de cerca de 50% da lesão; e nos cinco casos restantes, houve cicatrização de aproximadamente 75% da lesão. A primeira ultrassonografia de controle revelou esclerose completa dos vasos tratados em 19 dos 20 casos e esclerose parcial sem refluxo detectável em um caso. Na segunda ultrassonografia, realizada após 45 dias, observamos esclerose completa de 15 casos; em cinco casos, houve esclerose parcial, dos quais três sem refluxo detectável e dois com refluxo em segmentos isolados associados a varizes. A complicação mais frequente foi a pigmentação nos trajetos venosos, observada em 13 pacientes. Um caso apresentou trombose assintomática de veias musculares da perna. Conclusão Essa associação de procedimentos consiste em uma opção válida com potencial para promover um tratamento mais breve e de menor custo. PMID:29930660

Introducción: los problemas relacionados con el peso constituyen un problema importante de salud pública debido a su alta prevalencia y a las adversas consecuencias que tienen para la salud.Objetivo: el objetivo principal de este estudio fue analizar si la depresión y la ansiedad tienen un papel mediador en la relación entre la insatisfacción corporal y las conductas de control del peso en chicas adolescentes con sobrepeso.Material y métodos: en el estudio participaron 140 mujeres de 16 a 20 años con sobrepeso. Las participantes tuvieron que cumplimentar la escala de insatisfacción corporal del EDI-2, las escalas de ansiedad y depresión del GHQ-28 y una adaptación de las escalas del EAT survey para evaluar las conductas de control del peso. Para los análisis estadísticos se utilizaron métodos de diferencias de medias, correlaciones y de mediación secuencial.Resultados: las adolescentes con sobrepeso y alta insatisfacción corporal presentaban más sintomatología ansiosa y depresiva, así como mayor cantidad de conductas de control del peso. Los resultados del análisis de mediación secuencial evidencian que el efecto de la insatisfacción corporal en las conductas de control del peso está parcialmente mediado por las variables depresión y ansiedad. Mientras que la sintomatología ansiosa presenta efectos directos e indirectos sobre las conductas de control de peso, la sintomatología depresiva solamente presenta un efecto indirecto.Conclusiones:los resultados del estudio destacan el rol mediador de la sintomatología depresiva y, especialmente, de la ansiedad en el desarrollo de conductas no saludables de control del peso.

In June 2011, the Track Fire burned 113 square kilometers in Colfax County, northeastern New Mexico, and Las Animas County, southeastern Colorado, including the upper watersheds of Chicorica and Raton Creeks. The burned landscape is now at risk of damage from postwildfire erosion, such as that caused by debris flows and flash floods. This report presents a preliminary hazard assessment of the debris-flow potential from basins burned by the Track Fire. A pair of empirical hazard-assessment models developed using data from recently burned basins throughout the intermountain western United States were used to estimate the probability of debris-flow occurrence and volume of debris flows at the outlets of selected drainage basins within the burned area. The models incorporate measures of burn severity, topography, soils, and storm rainfall to estimate the probability and volume of post-fire debris flows following the fire. In response to a design storm of 38 millimeters of rain in 30 minutes (10-year recurrence-interval), the probability of debris flow estimated for basins burned by the Track fire ranged between 2 and 97 percent, with probabilities greater than 80 percent identified for the majority of the tributary basins to Raton Creek in Railroad Canyon; six basins that flow into Lake Maloya, including the Segerstrom Creek and Swachheim Creek basins; two tributary basins to Sugarite Canyon, and an unnamed basin on the eastern flank of the burned area. Estimated debris-flow volumes ranged from 30 cubic meters to greater than 100,000 cubic meters. The largest volumes (greater than 100,000 cubic meters) were estimated for Segerstrom Creek and Swachheim Creek basins, which drain into Lake Maloya. The Combined Relative Debris-Flow Hazard Ranking identifies the Segerstrom Creek and Swachheim Creek basins as having the highest probability of producing the largest debris flows. This finding indicates the greatest post-fire debris-flow impacts may be expected to Lake Maloya

, fluvial incision became preponderant while second generation alluvial fans and floodplains were formed. Therefore, the specific analysis of entrenchment indicators shows evidence of a vertical incision tendency of the drainage network. The obtained data allowed us to estimate an approximate mean entrenchment rate of 1,07 mm/year since the end of the Pleistocene glacial period. Compared with the 0,08-0,19 mm/year regional uplift rate, the dynamics of the Garona River is probably a combination of climatic (interglacial period), tectonic (uplift and erosional tendency of the axial Pyrenees since the Miocene), topographic (high gradients) and anthropic (engineering structures) factors, and also an intense glacial deposits erosion. In conclusion, the incision tendency hypothesis was confirmed, which is directly related to the geomorphological response after the last glaciation and is probably related to the evolution of the Pyrenean axial zone. Moreover, the long-term entrenchment dynamics determines present short-term fluvial processes, produces changes in flood hazard and controls the flood effects (see Garcia-Silvestre et al., also presented in EGU 2015). Thereby, this entrenchment tendency has consequences that must be considered when designing structural mitigation measures against flooding events.

especialistas fueron liberados y establecidos en los 80s. Consecuentemente, la produccion comercial del nematodo fue iniciada, casi 70 billones fueron aplicados en 34 condados de la Florida, y se realizo un monitoreo para evaluar su establecimiento, dispersion e impacto sobre los grillotopos. Los gillotopos infectados dispersaron los nematodos rapidamente, tanto que despues de 6 meses estos parasitos estaban presentes en la mayoria de los insectos atrapados en los pastos experimentales. Tres anos despues, las poblaciones de los grillotopos fueron reducidas a niveles aceptables y los campos de pasto 'bahia' se recuperaron. El nematodo fue liberado para la primera vez en Puerto Rico durante del 2001 y ha persistido; la avispa fue introducida al final de los 30s. La distribucion geografica de la avispa se esta extendiendo en la Florida y Puerto Rico por medio de la siembra de parcelas de Spermacoce verticillata, una flor silvestre indigena a Puerto Rico y distribuida ampliamente en el sur de la Florida. Los campos de pasto, las operaciones comerciales de cesped, los campos de golf, los paisajes y las fincas de hortalizas en la Florida y Puerto Rico se estan beneficiando del control biologico de los grillotopos invasores.

apresentavam hipoalbuminemia. a prevalência de hipoalbuminemia mostrou-se elevada, acometendo aproximadamente nove entre dez idosos, sendo que o estado nutricional, da mesma maneira que o tempo de internação , está relacionado à diminuição dos níveis de albumina sérica. Assim, sugere-se monitorar os níveis de albuminemia para avaliar o risco que o paciente tem de desenvolver desnutrição e demais complicações durante a internação hospitalar. estimar la prevalencia de hipoalbuminemia en ancianos hospitalizados, considerando las variables sociodemográficas, estado nutricional y tiempo de internación. estudio transversal, en 200 pacientes internados en hospital de gran porte del sur de Brasil, durante un período de tres meses. Fueron realizadas evaluaciones, análisis de exámenes de laboratorio y se realizó una entrevista usando un cuestionario. el promedio de albuminemia fue 2,9 ± 0,5g/dL. El diagnóstico de hipoalbuminemia, fue encontrado en 173 sujetos (87%), y no revelado en 27 (13%), que presentaron albuminemia normal (p=0,000). Se constató que después de seis días de internación la prevalencia de niveles bajos aumentó significativamente para 90% (p=0,002), con promedio de 2,7 ± 0,5g/dL. Utilizando la Mini Evaluación Nutricional, se observó que 41 pacientes estaban desnutridos, y que de estos, 40 presentaban hipoalbuminemia. la prevalencia de hipoalbuminemia se mostró elevada, afectando aproximadamente nueve entre diez ancianos, siendo que el estado nutricional, de la misma manera que el tiempo de internación, está relacionado a la disminución de los niveles de albúmina sérica. Así, se sugiere monitorizar los niveles de albuminemia para evaluar el riesgo que el paciente tiene de desarrollar desnutrición y demás complicaciones durante la internación hospitalaria.

Based on the readings of articles related to Astronomy Education published in Brazil, it was noticed a lack of research on previous knowledge of students about the physical characteristics of stars, a fact that motivated us to develop this study. Previous knowledge of 125 students (approximated 15 years old) constituted the study sample; data was collected through written questionnaires (Appendix A) for analysis. From the content analysis of these responses it was possible to achieve some inferences as, for example, many students have some difficult to develop an explanatory model on the functioning of a star; there are few who say that the stars have a certain length of existence; some students have said that stars have tips; few recognize that a star is formed by a mass of gas; some previous knowledge come from purely visual aspects; furthermore, some students do not have the habit of observing nature in detail. We see this research as a reference in which science teachers can recognize the importance of previous knowledge for practice teaching and acquire resources for planning their lessons. De la lectura de artículos relacionados con la Educación en Astronomía publicados en el Brasil, se encuentra una falta de investigaciones acerca del conocimiento previo de los estudiantes sobre las características físicas de las estrellas, hecho que nos motivó a desarrollar este estudio. Los datos analizados se obtuvieron al aplicar un cuestionario a 125 estudiantes de secundaria, para posteriormente realizar un análisis de contenido, tal cuestionario se presenta en el Anexo A. Al realizar el análisis de contenido de las respuestas obtenidas, fue posible hacer algunas inferencias, como por ejemplo; muchos estudiantes tienen dificultades para desarrollar un modelo explicativo acerca del funcionamiento de una estrella; pocos estudiantes dicen que las estrellas tienen un cierto tiempo de vida; algunos estudiantes imaginan que las estrellas tienen puntas; pocos

This work analyses results obtained in a solar physics course for high school students promoted at the Dietrich Schiel Observatory of the University of São Paulo (USP). The course was elaborated by the authors with the intention of investigating student's concepts about the Sun, teaching topics of modern physics related to the Sun and providing students with knowledge about our star as well. The methodology of data gathering consisted of audio and video records of classes and of semi-structured interviews, and analysis of answers to written questionnaires. The results showed that most high school students conceived the Sun as made of fire, while sunspots were thought to be holes in the Sun. Even though some students did know that a spectrum is formed using a prism or diffraction grating, most of them ignored the nature of the observed spectral lines. Through the course, this topic was developed by means of a practical approach with solar and lamp spectra observations. The results obtained in the course point to the importance of science centers as partners in formal education. In this specific case, the Solar Room at the Dietrich Schiel Observatory is as a favorable environment for teaching modern physics in high school. Este artículo analiza los resultados obtenidos en un curso sobre la física solar, auspiciado por el Observatorio Dietrich Schiel de la USP para estudiantes de las escuelas secundarias. El curso fue diseñado por los autores con la intención de investigar las concepciones sobre el sol, enseñar temas relacionados con la física moderna del Sol y conocimientos generales sobre el astro rey. La metodología utilizada para la recolección de datos consistió en grabar, en audio y video, las clases, las entrevistas semi-estructuradas y las respuestas a los cuestionarios escritos. Los resultados mostraron que la mayoría de los participantes conciben el Sol como constituido por fuego y las manchas solares en la superficie solar como agujeros. Aunque

to identify the factors related to the quality of umbilical cord and placental blood specimens, and define best practices for their collection in a government bank of umbilical cord and placental blood. this was a descriptive study, quantitative approach, performed at a government umbilical cord and placental blood bank, in two steps: 1) verification of the obstetric, neonatal and operational factors, using a specific tool for gathering data as non-participant observers; 2) definition of best practices by grouping non-conformities observed before, during and after blood collection. The data was analyzed using descriptive statistics and the following statistical software: Statistica(r) and R(r). while there was a correlation with obstetrical and neonatal factors, there was a larger correlation with operational factors, resulting in the need to adjust the professional practices of the nursing staff and obstetrical team involved in collecting this type of blood. Based on these non-conformities we defined best practices for nurses before, during and after blood collection. the best practices defined in this study are an important management tool for the work of nurses in obtaining blood specimens of high cell quality. identificar fatores relacionados à qualidade das amostras do sangue de cordão umbilical e placentário e definir boas práticas para sua coleta em um banco público de sangue de cordão umbilical e placentário. pesquisa descritiva, abordagem quantitativa, realizada em um banco público de sangue de cordão umbilical e placentário, desenvolvida em duas etapas: 1) verificação dos fatores obstétricos, neonatais e operacionais, obtidos por coleta em instrumento próprio e observação não participante; 2) definição das boas práticas, por meio do agrupamento de não-conformidades observadas antes, durante e após a coleta do sangue. Os dados foram analisados por meio da estatística descritiva, utilizando-se dos softwares Statistica(r) e R(r). houve

To evaluate the prevalence of health-related behaviors according to presence and type of depression in Brazilian adults. Based on a sample of 49,025 adults (18 to 59 years) from the National Survey on Health 2013 (PNS 2013), we estimated the prevalence of health-related behaviors (smoking; passive smoking; frequent or risky alcohol consumption; leisure time physical activity; time watching TV; and eating pattern indicators), according to the presence of depression (minor and major), evaluated by the Patient Health Questionnaire - 9 (PHQ-9), and the report of depressive mood (in up to seven days or more than seven days) over a two-week period. Prevalence ratios were estimated by Poisson regression. Evaluated by the PHQ-9 scale, 9.7% of the Brazilian adults had depression and 3.9% presented major depression. About 21.0% reported depressive mood and, in 34.9% of them, that feeling has been present for more than seven days. In individuals with major depression (PHQ-9), higher prevalence was found in almost all unhealthy behaviors analyzed, in particular, smoking (PR = 1.65), passive smoking (PR = 1.55), risk alcohol consumption (PR = 1.72), TV for ≥ 5 hours/day (PR = 2.13), consumption of fat meat (PR = 1.43) and soft drink (PR = 1.42). The prevalence ratios tended to be lower in those with minor depression. Similar results were observed in adults with depressive mood. This study detected relevant association between depression and health behaviors, in particular for smoking and physical activity. The associations found with the PHQ were similar to those observed with the application of a single question about depressive mood. Our results indicate the importance of assessing the presence of depression and the frequency and severity of symptoms when implementing actions for the promotion of healthy behaviors. Avaliar a prevalência de comportamentos relacionados à saúde segundo a presença e tipo de depressão em adultos brasileiros. Com base em amostra de 49

A astronomia, embora seja uma ciência popular, com inúmeras descobertas de interesse público, ainda é apresentada desconsiderando-se os aspectos históricos e científicos relacionados ao seu desenvolvimento, sendo geralmente veiculada nos meios de comunicação de maneira pouco esclarecedora e não raro com imprecisões. Neste trabalho analisou-se a concepção de um grupo de estudantes de Ensino Médio sobre conceitos de astronomia, visando identificar sua visão de mundo a respeito do Universo, envolvendo idéias sobre espaço e tempo. Para issso, foi aplicado um questionário em três escolas da grande São Paulo em um espaço amostral de 270 alunos. Constatou-se que, embora o ensino de astronomia esteja previsto nos PCNEM, os resultados obtidos na pesquisa mostram que há grande deficiência no conhecimento dos temas investigados. Nesse sentido, verificou-se que apenas 20% dos alunos eram capazes de relacionar a sucessão das semanas com as fases da lua, enquanto 28% associaram as estações do ano à inclinação do eixo de rotação da Terra. Por outro lado, somente 23% dos alunos tinham noções das distâncias entre os objetos celestes próximos da Terra e 56% conseguiram relacionar o Big Bang com a origem do Universo. Finalmente, constatou-se que 37% reconheciam o ano-luz como uma unidade de distância e 60% reconheciam o Sol como sendo uma estrela. Apesar de 60% dos alunos indicarem que a escola é a principal fonte para aquisição dos conhecimentos de astronomia, conclui-se que seus conceitos nessa área ainda são inadequados, havendo necessidade de ampliação e aprimoramento da abordagem desses conteúdos nos ambientes escolares.

Introducción. La etapa posprandial se asocia con el incremento de marcadores relacionados con el riesgo cardiovascular, cuya intensidad depende del estado metabólico.Objetivo. Determinar el impacto de la ingestión de una comida rica en grasas saturadas sobre el perfil metabólico e inflamatorio y su relación con la obesidad abdominal.Materiales y métodos. Se hizo un ensayo clínico en 42 individuos (21 con obesidad abdominal). Se midieron, en sangre, la glucosa, la insulina, el perfil lipídico, la proteína C reactiva, los lipopolisacáridos y la interleucina 6, en ayunas y después de la ingestión.Resultados. Además de la obesidad, se registró la presencia de resistencia a la insulina y de niveles elevados de triacilglicéridos y proteína C reactiva en ayunas. Asimismo, se detectaron niveles posprandiales más elevados de glucosa, insulina y triacilglicéridos. La interleucina 6 disminuyó en el grupo de personas sin obesidad y los lipopolisacáridos aumentaron en ambos grupos.Conclusión. La ingestión de una comida rica en grasas saturadas produjo un mayor impacto en las variables glucémicas en el grupo con obesidad y, aunque afectó de forma similar los lípidos en ambos grupos, el incremento de triacilglicéridos fue mayor en presencia de una concentración basal elevada y promovió el aumento de lipopolisacáridos. El estado inflamatorio basal y posprandial afectó en mayor medida al grupo con obesidad. El momento posprandial reflejó el estado más frecuente de los individuos en un día normal y permitió evidenciar la capacidad de respuesta metabólica frente a la ingestión de alimentos, así como los estados tempranos de riesgo metabólico.

En esta investigacion, se desarrollo un instrumento que permite medir percepciones relacionadas al contexto de constriccion del conocimiento cientifico. Se examinaron instrumentos existentes y se encontro que el VOSTS (Views on science, technology, and society), instrumento desarrollado empiricamente en Canada por Aikenhead, Ryan y Fleming, podia traducirse y validarse en el contexto cultural puertorriqueno. El instrumento es extenso, consta de 113 reactivos, cada uno con una premisa basica relacionada a la tematica ciencia, tecnologia y sociedad y un numero de alternativas relacionadas a la premisa que oscila entre siete y trece. Se delimito su utilizacion a los quince reactivos identificados por los autores como relacionados a la construccion social del conocimiento cientifico. Metodologicamente, se procedio a utilizar el modelo de adaptacion intercultural, que permite que el instrumento desarrollado satisfaga las dimensiones de equivalencia semantica, de contenido, tecnica, de criterio y conceptual, atemperado asi al instrumento original. Se cumplio con este proposito mediante la traduccion de la version original en ingles al espanol y viceversa. Se utilizaron comites para examinar la traduccion y la retro-traduccion del instrumento. Se realizo una prueba piloto con estudiantes universitarios de nuevo ingreso, utilizando el instrumento traducido para asegurar su intelegibilidad. La confiabilidad del instrumento se determino mediante la intervencion de un panel de expertos quienes clasificaron las distintas posiciones dentro de cada reactivo en: realista, con merito e ingenua; se transformaron estas opciones en valores numericos lo que permitio establecer una escala Likert para cada una. Se suministro el instrumento a una muestra de estudiantes universitarios de nuevo ingreso con caracteristicas similares a las de la poblacion puertorriquena en cuanto a ejecucion en las pruebas de aptitud verbal y matematica del College Board.

Resumen El rastreo de cáncer colorrectal (CCR) cuenta con fuertes evidencias en su favor. Datos preliminares indican que a pesar de ello no se lleva a cabo con la frecuencia adecuada. Se intenta aquí determinar, dentro de un Sistema de Salud que cuenta con los recursos necesarios, los elementos que facilitan o generan barreras para concretar esta práctica preventiva, cuántos individuos lo ponen en práctica y qué predice esta conducta. Se realizó una encuesta telefónica a los afiliados de una Obra Social de empleados de la Universidad de Buenos Aires, de los que 132 completaron el cuestionario (tasa de respuesta 70%). Los elementos considerados facilitadores del rastreo obtuvieron respuestas afirmativas en el 64 a 97%, mientras que los que definían barreras un 11 a 27%. En este último grupo, una categoría diferenciada la constituía el miedo a los efectos adversos: 39%, y el sentimiento de vergüenza relacionado con los procedimientos: 30%. Un 33% de los encuestados tenían hecho un método de rastreo, mayoritariamente de sangre oculta (27), sigmoideoscopía (11) y colonoscopía (20). Una mayoría afirmó que “se haría el procedimiento si el médico se lo recomendara” (95%), o “no se lo haría excepto que su médico se lo aconseje” (87%). Contestar afirmativamente que “los médicos hacen lo mejor para los pacientes” se asoció con haberse hecho un método de rastreo de CCR, OR 1.55 (IC 95%: 1.02-2.37) p: 0.04. El grupo de individuos estudiado parece bien predispuesto para el rastreo del CCR, la recomendación médica sería aquí un determinante prominente para ponerlo en práctica. PMID:19414294

Este estudio se enfoco en los "misconception" y lagunas conceptuales en temas fundamentales de Fisica como son Equilibrio Termodinamico y Estatica de fluidos. En primer lugar se trabajo con la identificacion de "misconceptions" y lagunas conceptuales y se analizo en detalle la forma en que los estudiantes construyen sus propias teorias de fenomenos relacionados con los temas. Debido a la complejidad en la que los estudiantes asimilan los conceptos fisicos, se utilizo el metodo de investigacion mixto de tipo secuencial explicativo en dos etapas, una cuantitativa y otra cualitativa. La primera etapa comprendio cuatro fases: (1) Aplicacion de una prueba diagnostica para identificar el conocimiento previo y lagunas conceptuales. (2) Identificacion de "misconceptions" y lagunas del concepto a partir del conocimiento previo. (3) Implementacion de la intervencion por medio de modulos en el topico de Equilibrio Termodinamico y Estatica de Fluidos. (4) Y la realizacion de la pos prueba para analizar el impacto y la efectividad de la intervencion constructivista. En la segunda etapa se utilizo el metodo de investigacion cualitativo, por medio de una entrevista semiestructurada que partio de la elaboracion de un mapa conceptual y se finalizo con un analisis de datos conjuntamente. El desarrollo de este estudio permitio encontrar "misconceptions" y lagunas conceptuales a partir del conocimiento previo de los estudiantes participantes en los temas trabajados, que fueron atendidos en el desarrollo de las distintas actividades inquisitivas que se presentaron en el modulo constructivista. Se encontro marcadas diferencias entre la pre y pos prueba en los temas, esto se debio al requerimiento de habilidades abstractas para el tema de Estatica de Fluidos y al desarrollo intuitivo para el tema de Equilibrio Termodinamico, teniendo mejores respuestas en el segundo. Los participantes demostraron una marcada evolucion y/o cambio en sus estructuras de pensamiento, las pruebas estadisticas

Se han obtenido observaciones desde Tierra (Hα y magnetogramas) coordinadas con el Soft X-ray Telescope (SXT), a bordo del satélite japonés Yohkoh, de una región activa bipolar en decaimiento. Estos datos constituyen la base para el estudio de un punto brillante en rayos X (PBX) y de la actividad relacionada con el mismo en distintas capas de la atmósfera solar. Las observaciones muestran que el PBX está relacionado con la aparición de un bipolo menor (~ 1020 Mx) y que su abrillantamiento continuo, así como sus aumentos de brillo esporádicos (``fulguraciones"), son el resultado de la reconexión entre el pequeño arco emergente (visto en Hα como un sistema de filamentos arqueados, SFA) y arcos mayores asociados al campo facular preexistente. Se ha extrapolado el campo magnético observado en la aproximación libre de fuerzas lineal y se ha seguido su evolución a lo largo de la vida del PBX. Se ha calculado la posición de las cuasiseparatrices (CSs) a partir del campo modelado. Las líneas de campo extrapoladas, cuyas bases fotosféricas se encuentran a ambos lados de las CSs, están de acuerdo con las estructuras cromosféricas y coronales observadas. Se ha calculado el espesor de la CD ubicada a lo largo de la polaridad negativa emergente, encontrándose que su variación está de acuerdo con la evolución de la intensidad del PBX; la CS es muy delgada durante la vida del PBX (~ 100 m), mientras que su espesor aumenta considerablemente (>= 10^4 m) cuando el PBX desaparece de las imágenes del SXT. Estos resultados señalan que el abrillantamiento y las ``fulguraciones" de este PBX se deben al proceso de reconexión en 3D que tiene lugar en las CSs.

Introducción Las mujeres Hispanas de 50 años y más (MHC) son una minoría en Estados Unidos que está a elevado riesgo de adquirir VIH y son el grupo menos estudiado en lo que respecta a salud, características sociales y de comportamiento sexual. Objetivo Investigar los factores que incrementan el riesgo de VIH en las MHC con el propósito de desarrollar o adaptar una intervención apropiada para la “edad y la cultura "de este grupo de mujeres. Metodología Estudio descriptivo de corte transversal con una muestra de 50 MHC, sexualmente activas y que residían en Miami, Florida, Estados Unidos. Se utilizó un cuestionario estructurado administrado por entrevistadores entrenados y bilingües (inglés/español). Las participantes fueron reclutadas en diferentes lugares en el Sur de Florida. Para el análisis de los datos se utilizó estadística descriptiva, tanto medidas de tendencia central como medidas de dispersión. Resultados La edad promedio de las MHC fue de 55,7 ± 6 años (rango 50–76 años). Todas las MHC estaban en la menopausia. Prevención del VIH Las MHC reportaron niveles medios de conocimientos sobre VIH y comunicación con la pareja. En la muestra se reportó la presencia de síntomas depresivos, violencia en la pareja, actitudes negativas hacia las personas viviendo con VIH y baja percepción de riesgo de adquirir VIH. Las MHC mencionaron necesidades de aprendizaje en tópicos relacionados con prevención de VIH y cambios de la edad. Conclusión Las MHC están a riesgo de adquirir VIH y tienen necesidades especiales en términos de educación sobre prevención de VIH. PMID:25242862

Resumen Estudios previos en Buenos Aires reportaron altas prevalencias de HIV entre HSH, con valores que oscilan entre 9 y 14% durante casi 10 años de continuo testeo. El objetivo principal de este estudio fue la evaluación de factores relacionados al comportamiento de alto riesgo para transmisión del HIV entre HSH entre los que se incluyen el conocimiento y factores emocionales, socioculturales y ambientales. Por otro lado se realizó la estimación de prevalencia e incidencia de HIV utilizando RDS (Respondent Driven Sampling), así como la presencia de otras infecciones de transmisión sexual. Por último se evaluaron los hábitos de testeo para HIV indagando que factores facilitan o impiden su realización. El estudio constó de dos fases, en primer lugar una fase cualitativa y posteriormente una fase cuantitativa con una duración total de 4 años y medio. Durante la fase cualitativa se realizaron 44 entrevistas individuales en profundidad, 8 grupos focales y 10 observaciones etnográficas (hoteles, baños públicos (“teteras”), cines pornográficos, fiestas privadas, dark rooms y discotecas). Durante la fase cuantitativa del estudio se realizó el reclutamiento de 500 participantes que provinieron de la Ciudad Autónoma de Buenos Aires, así como del Gran Buenos Aires. El reclutamiento se comenzó con 16 participantes llamados semillas. Se realizó el diagnóstico de infección por HIV, hepatitis B y C (HBV y HCV), Treponema pallidum, Virus Papiloma Humano (HPV) y Chlamidias. La colaboración establecida entre los grupos de trabajo enfocados en áreas diversas posibilitó el abordaje conjunto de nuevas estrategias de investigación antes no exploradas en nuestro país. Los resultados más relevantes de esta investigación serán progresivamente publicados en sucesivos números de Actualizaciones en SIDA. PMID:25264397

Este folleto contiene historias veridicas que ilustran como sobrevivir, y como no sobrevivir, a un tsunami. Esta publicacion esta dirigida a las personas que viven, trabajan o, simplemente, se divierten a lo largo de las costas que pueden ser afectadas por un tsunami. Tales costas rodean la mayor parte del Oceano Pacifico pero tambien incluyen algunas areas costeras de los Oceanos Atlantico e Indico. Aunque mucha gente llama a los tsunamis 'olas de marea', estos no estan relacionados a las mareas, sino son una serie de olas, o 'tren de olas', generalmente causadas por cambios en el nivel del fondo marino durante los terremotos. Los tsunamis tambien pueden ser generados por la erupcion de volcanes costeros, islas volconicas, deslizamientos submarinos e impactos de grandes meteoritos en el mar. Como sucedio en Sumatra en el 2004, los tsunamis pueden alcanzar alturas de 15 metros, no tan solo en la costa sino tambien kilometros tierra adentro. Los relatos presentados en este folleto fueron seleccionados de entrevistas realizadas a personas que sobrevivieron al tsunami del Oceano Pacifico de 1960. Muchas de estas personas, incluyendo a la enfermera de la foto, se enfrento a las olas generadas a poca distancia, en la costa chilena. En cambio, otros debieron hacer frente al tsunami muchas horas despues, en Hawai y Japon. La mayoria de las entrevistas fueron realizadas a fines de los anos ochenta y en los noventa. Las historias ofrecen una mezcla de lecciones de supervivencia a un tsunami. En algunos casos se presentan las acciones que confiablemente salvaron vidas: poner atencion a los avisos de la naturaleza, abandonar los bienes, dirigirse rapidamente a un sector alto y permanecer alli hasta que el tsunami realmente haya terminado. Otras historias describen como se encontro refugio al subir a construcciones y arboles o flotar sobre desechos, tacticas que tuvieron diferentes resultados y que pueden ser recomendadas solo como actos desesperados de personas atrapadas en
A cosmologia no ensino da geografia

O principal objetivo deste trabalho é auxiliar o professor de Geografia em sala de aula no ensino de tópicos relacionados com a Cosmologia. A idéia deste trabalho surgiu quando foi constatado que o professor de Geografia tem dificuldades de ensinar este tópico. Esta constatação foi feita por uma das autoras ao lecionar este tópico no ensino fundamental e em discussões com outros professores de Geografia. Da mesma maneira que ocorria desde os tempos mais antigos, os alunos têm muito interesse em conhecer os fenômenos que ocorrem no Cosmo, porém os livros didáticos de Geografia utilizados em sala de aula não são ricos em informações sobre este assunto. Assim, o professor de Geografia tem poucas informações para discutir este assunto em sala de aula e não dá a devida importância para este tópico. Então, foi desenvolvido um material de apoio para professores de Geografia sobre a origem do Universo, sua evolução e seu possível futuro evolutivo segundo as mais recentes teorias, com base em perguntas feitas pelos alunos de ensino fundamental e as informações trazidas nos livros didáticos Não cabe a este material inovar e tão pouco trazer uma metodologia de ensino de Cosmologia. Neste material o professor de Geografia pode encontrará um banco de informações, que constitui no estabelecimento de conceitos, teorias e hipóteses, sobre a Cosmologia, em linguagem simples e de fácil entendimento. Para desenvolvê-lo, foram feitas pesquisas não exaustivas em livros e revistas científicas, compilação e discussão em forma cronológica das teorias aceitas sobre modelos cosmológicos. Portanto, este material será apresentado neste trabalho.

A pesquisa sobre remanescentes de aglomerados abertos tem despertado grande interesse. Seguindo esta tendência encontramos estudos teóricos e observacionais. Os primeiros baseiam-se em simulações numéricas buscando determinar fração de binárias e distâncias galatocêntricas, tempo de vida e conteúdo estelar. Estes estão relacionados à função inicial de massa e densidade de estrelas, ou seja, se ricos ou pobremente povoados, compactos ou esparsos. No caso observacional procuram-se identificar os remanescentes considerando-se que trazem estas assinaturas de seus percursores. No presente estudo empregamos espectroscopia para analisar oito concentrações pobremente povoadas, previamente classificadas como aglomerados abertos, sendo sete compactas e uma esparsa. As observações foram obtidas através do telescópio de 2,15 m do CASLEO em San Juan, Argentina, em turnos entre 2001 e 2003. Utilizamos uma câmara CCD contendo um chip Tektronics de 1024X1024 pixeis aliado a um espectrógrafo REOSC. O domínio espectral vai de 3700 a 7000 Å. As reduções foram realizadas no Observatório Astronômico de Córdoba (Argentina) usando pacotes IRAF padrões. Determinamos idades, avermelhamentos e tipos espectrais através de comparações com biblioteca de estrelas e de aglomerados. Em alguns casos nossos espectros estavam dominados por estrelas individuais às quais determinamos seus tipos espectrais. Aos oito objetos adicionamos mais cinco da literatura recente analisados via espectro ou diagrama cor-magnitude. O histograma resultante contém idades típicas entre 0.5 e 3 Ganos. Considerando que predominantemente estes objetos encontram-se na vizinhança solar e, portanto, não cruzaram muitas vezes o plano Galático esperamos que a diferença no tempo necessário para dissolução destes prováveis remanescentes seja em função de diferentes massas iniciais.
ARTERIAL HYPERTENSION AND IRRADIATION DAMAGE TO THE NERVOUS SYSTEM

On the basis of previous studies it appeared that irradiation damage to the nervous system might be more severe and more easily produced in hypertensive than in normotensive subjects. This hypothesis was investigated by studying the frequency of neurological complications and vascular lesions in the spinal cord after x irradiation of the cord in hypertensive and normotensive rats. Two weeks before irradiation of the spinal cord, a clip was applied to the right renal artery of the animals to produce hypertension. Single doses of 1500, 2000, or 3000 r were administered to the spinal cord in the cervical and uppermore » thoracic region of hypertensive rats (systolic blood pressure higher than 145 mm Hg) and normotensive rats. After 1500 r to spinal cord, no abnormalities were noted in the normotensive controls during the period of observation. Some hypertensive animaIs showed transient abnormalities of gait, and during the following week died suddenly. Those remaining died unexpectedly 35-259 days after irradiation without apparent preceding neurological manifestations, although acute vascular lesions were found in the irradiated regions of the spinal cord. The normotensive controls of the 2000-r group showed no abnormalities of gait or of tail sensation, but the hypertensive rats died 67-243 days after irradiation, and ntaxic episodes preceding these unexpected deaths in one animal. Ristologically, the irradiated segments of the cords showed multiple focal acute vascular necrosis. The smaller arteries in irradiated segments of the cords showed hyaline thickening; some of the smaller vessels were widely dilated and filled with blood, and their walls were necrotic. The white matter of the irradiated parts of these cords showed numerous holes (status spongiosus) in the lateral and dorsal columns. The anterior-horn cells in the irradiated zones were swollen, their nuclei pyknotic and cytoplasm devoid of Nissl granules. No abnormalities, besides thickening of the

he accuracy of precipitation forecasts over the northeastern United States, but overall, the accuracy of MOS-based precipitation forecasts is slightly lower than the raw NCEP forecasts. Four basins in the United States were chosen as case studies to evaluate the value of MRF output for predictions of streamflow. Streamflow forecasts using MRF output were generated for one rainfall-dominated basin (Alapaha River at Statenville, Georgia) and three snowmelt-dominated basins (Animas River at Durango, Colorado: East Fork of the Carson River near Gardnerville, Nevada: and Cle Elum River near Roslyn, Washington). Hydrologic model output forced with measured-station data were used as "truth" to focus attention on the hydrologic effects of errors in the MRF forecasts. Eight-day streamflow forecasts produced using the MOS-corrected MRF output as input (MOS) were compared with those produced using the climatic Ensemble Streamflow Prediction (ESP) technique. MOS-based streamflow forecasts showed increased skill in the snowmelt-dominated river basins, where daily variations in streamflow are strongly forced by temperature. In contrast, the skill of MOS forecasts in the rainfall-dominated basin (the Alapaha River) were equivalent to the skill of the ESP forecasts. Further improvements in streamflow forecasts require more accurate local-scale forecasts of precipitation and temperature, more accurate specification of basin initial conditions, and more accurate model simulations of streamflow. ?? 2004 American Meteorological Society.

Objetivos. Nos propusimos determinar el grado de preparación frente a los desastres naturales de los adultos mayores en los Estados Unidos y evaluar los factores que pueden afectar negativamente la salud y la seguridad durante este tipo de incidentes. Métodos. Obtuvimos una muestra de adultos de 50 años en adelante (n = 1 304) de la encuesta del 2010 del Estudio de la Salud y la Jubilación (HRS por su sigla en inglés). La encuesta recogió datos sobre las características demográficas generales, el estado de discapacidad o las limitaciones funcionales, y también sobre factores y comportamientos relacionados con la preparación frente a los desastres. Calculamos una puntuación global de preparación mediante indicadores individuales a fin de evaluar el grado de preparación general. Resultados. La media de la edad de los participantes (n = 1 304) fue de 70 años (desviación estándar [DE] = 9,3). Solo 34,3% informaron que habían participado en un programa formativo o que habían leído materiales sobre la preparación para los desastres. Casi 15% indicaron que usaban dispositivos médicos eléctricos que podían correr riesgo de no funcionar si se interrumpiera el suministro eléctrico. La puntuación de preparación indicó que la edad más avanzada, la discapacidad física y el menor nivel de escolaridad y de ingresos se asociaban independiente y significativamente a un grado de preparación general inferior. Conclusiones. A pesar de la mayor vulnerabilidad ante los desastres y del número cada vez mayor de adultos mayores en los Estados Unidos, muchos de los problemas sustanciales que encontramos son remediables y requieren atención en los sectores de la sociedad dedicados a la atención clínica, a la salud pública y al manejo de situaciones de emergencia.

Este texto apresenta resultados de uma investigação que teve como objetivo, investigar como os conhecimentos científicos e do cotidiano relacionados a essa área de conhecimento apresentam na escola de Educação Básica, especialmente, em alunos do Ensino Médio prestes a deixar Educação Básica. Para realização da pesquisa, utilizamos como recurso metodológico a aplicação de um questionário estruturado contendo 47 questões, organizadas em duas categorias: Conhecimento Cotidiano e Conhecimento Científico. As questões da categoria “Conhecimento Cotidiano” possuíam afirmações relacionadas a crendices, contos populares, especulações e temáticas do gênero, as quais, geralmente, estão fora do círculo de discussão da comunidade científica, talvez por não serem consideradas como objeto de estudo da ciência. As questões da categoria “Conhecimento Científico” são relacionadas a conteúdos específicos de Astronomia, as quais são compartilhadas pela comunidade científica e aceitas, pelo menos provisoriamente, como possuindo fundamentação científica. Concluímos que, possuem ainda concepções de temas Astronômicos persistentes à mudança, por exemplo, fases da Lua relacionadas à melhor período para corte de cabelo e também para plantio; estrela cadente e ocasião perfeita para se fazer um pedido. Entretanto, podemos observar no que diz respeito a mitos e superstições, que quase não existe influência destes entre os alunos. Portanto, ao trabalharmos com os alunos determinados conceitos científicos, é importante lembrarmos que o professor não opera no vazio; os alunos são sujeitos de saberes, práticas e, dessa forma constroem e reconstroem saberes. Cabe ao professor ouvir os estudantes reconstruindo junto deles conceitos científicos. Acreditamos que o ensino de Ciências na Educação Básica deve lidar criticamente com o conhecimento cotidiano e científico e, assim, efetivar a Ciência como disciplina educativa

A Rede Neural Artificial (RNA), no âmbito da teoria computacional, constitui uma teoria emergente que, por possuir habilidade em aprender a partir de dados de entrada, encontra diferentes aplicações em diferentes áreas. Um exemplo é a utilização de RNA na caracterização de padrões associados à dinâmica de processos espaço-temporais relacionados a fenômenos físicos não-lineares. Para obter informações sobre o comportamento destes fenômenos físicos utiliza-se, em diversos casos, seqüências de imagens digitalizadas, onde a caracterização de alguns fenômenos espaço-temporais é o procedimento mais viável para descrever a dinâmica das regiões ativas do Sol. Com base em imagens observadas por telescópios a bordo de satélites, estudos de previsão de eventos solares podem ser programados, permitindo prever possíveis efeitos posteriores nas regiões mais próximas da Terra (tempestades geomagnéticas e irregularidades ionosféricas). Neste trabalho avaliamos o desempenho da RNA para estimar padrões espaço-temporais, ou seja, imagens solares em ultravioleta, obtidas através do telescópio a bordo do satélite SOHO. Os resultados mostraram que as RNA conseguem generalizar os padrões de maneira satisfatória sem perder de forma significativa os principais aspectos da configuração global da atmosfera solar, comprovando a eficácia da RNA como ferramenta para esse tipo de aplicação. Portanto, este trabalho comprova a viabilidade de uso desta ferramenta em projetos voltados ao estudo do comportamento solar, em trabalhos do grupo de Física do Meio Interplanetário (FMI) na DAS e em programas desenvolvidos pelo Núcleo de Simulação e Análise de Sistemas Complexos (NUSASC) do Laboratório Associado de Computação e Matemática Aplicada (LAC) do INPE.

A razão para o desenvolvimento deste trabalho baseia-se no fato de que muitos professores da Educação Básica (EB) não lidam com conceitos relacionados à astronomia, e quando o fazem eles simplesmente seguem livros didáticos que podem conter erros conceituais. Como é de conhecimento geral a astronomia é um dos conteúdos a serem ensinados na EB fazendo parte dos Parâmetros Curriculares Nacionais e das Propostas Curriculares do Estado de São Paulo, mas é um fato, que vários pesquisadores apontam, a existência de muitos problemas no ensino da astronomia. Com o propósito de minimizar algumas dessas deficiências foi realizado um trabalho de pesquisa com a utilização de questionários pré e pós pesquisa, para tanto foi desenvolvido um Curso de Extensão Universitária para professores da Diretoria de Ensino Regional (DE) que abrange Mauá, Ribeirão Pires e Rio Grande da Serra (no Estado de São Paulo) com os seguintes objetivos: levantar concepções alternativas; subsidiar os professores por meio de palestras, debates e workshops, e verificar o sucesso da aprendizagem após o curso, adotando-se como referência, para a análise dos resultados, os dicionários de Língua Portuguesa (FERREIRA, 2004) e Enciclopédico de Astronomia e Astronáutica (MOURĀO, 1995). Portanto, dezesseis questões foram aplicadas antes e após o curso, assim pode-se verificar após a pesquisa que 100,0% dos professores sabiam os nomes das fases da Lua, 97,0% entenderam que o Sistema Solar é composto por oito planetas, 78,1% foram capazes de explicar como ocorre um eclipse lunar, um eclipse solar e um solstício, 72,7% sabiam como explicar a ocorrência das estações do ano; 64,5% explicaram corretamente a ocorrência do equinócio, 89,7% foram capazes de definir adequadamente o termo cometa; 63,6% definiram asteróide, 54,5% meteoro, 58,1% galáxia, e 42,4% planeta. Os resultados obtidos indicam uma aprendizagem significativa por parte dos participantes.

Antecedentes: Las enfermedades que afectan la órbita representan un desafío quirúrgico, en particular las que comprometen el ápex orbitario. Una vía óptima de acceso quirúrgico proporciona la mejor exposición permitiendo identificar ciertas estructuras anatómicas claves llamadas reparos anatómicos. Objetivo: Describir la anatomía endoscópica de la unidad estructural Fisura Orbitaria Inferior / Músculo de Müller a nivel del ápex orbitario generando así un nuevo reparo anatómico endoscópico. Material y método: Análisis descriptivo óseo de la fisura orbitaria inferior (FOI) en cráneos secos, disección y estudio bajo técnica endoscópica de 6 cabezas fijadas en formol y coloreadas; finalmente se tomaron distancias y ángulos a forámenes relacionados con el ápex orbitario a 10 cráneos secos. El análisis estadístico se realizó con el programa estadístico SPSS 17,0 (SPSS, Inc., Chicago, IL). Resultado: En todas las disecciones endoscópicas se pudo identificar la unidad fisura orbitaria inferior-músculo de Müller y también verificar su íntima relación con el ápex orbitario. Morfométricamente el foramen óptico y el foramen redondo mayor están a una distancia promedio de 65.19mm y 60.16mm respectivamente. Los ángulos promedio del FO fue de 13.32 grados y del FRM de19.31 grados. Hallamos correlación significativa entre CO. y el FRM sólo en el hemicráneo izquierdo, (Tau b de Kendall 0.69, P=0.006). No se encontraron diferencias anatómicas (o morfológicas) significativas entre lados. Conclusión: bajo técnica endoscópica la unidad Fisura Orbitaria Inferior-Músculo de Müller (FOI-MM) es un reparo anatómico constante, útil y seguro que permite el reconocimiento del ápex orbitario y sus áreas contiguas.

Tem-se constatado uma preocupante carência no ensino de astronomia nos diversos níveis de escolaridade. Neste trabalho discutimos várias práticas didático-pedagógicas que vimos desenvolvendo para crianças, jovens e adultos em processo de alfabetização, visando contribuir para reparar aquela carência. Propomos uma metodologia que incorpora as recentes exigências das políticas públicas educacionais, estimula o desenvolvimento de textos e materiais instrucionais, é compatível com a realidade desse público e é adaptável às respectivas faixas etárias. A observação do céu sempre esteve presente na vida de nossos antepassados, dando suporte à compreensão do ser humano como integrante da natureza. Visamos com este trabalho suprir a deficiência encontrada para se tratar a relação do ser humano com o céu, no ambiente escolar. Os resultados são animadores e envolvem práticas e textos que desenvolvemos e atividades realizadas pelos alunos. No primeiro grupo destacamos o desenvolvimento de várias práticas: "viagem aos planetas" (construímos o "foguete", os planetas em escala, contamos história e redigimos texto de orientação para os professores); "gnômon humano" (os próprios corpos dos alunos são usados para registrar o movimento aparente do Sol); "crateras da Lua" (concretização de "meteoritos" e "solo lunar" de gesso e exploração da relação entre energia cinética do bólido e tamanho da cratera formada); etc. No segundo grupo, produções de desenhos e redações e discussões dos alunos após a realização de cada prática, revelam que estas têm se mostrado muito eficientes, tanto para estimular a imaginação e a fantasia dos envolvidos, como para trabalhar-se habilidades, competências e conteúdos relacionados à astronomia, segundo uma perspectiva interdisciplinar contextualizada.

Resumen Objetivo: Comparar el porcentaje de recurrencias en pacientes con meningiomas grado I de la OMS sometidos a exéresis microquirúrgica. Introducción: En 1957 Simpson estandarizó 5 grados de resección quirúrgica para los meningiomas intracraneanos y el porcentaje de recurrencia relacionado con cada uno, estableciendo el paradigma de que la remoción agresiva de estos tumores junto con fragmentos durales y óseos era necesario para alcanzar la curación. Los avances principalmente en Resonancia Magnética, anatomía patológica y técnica microqurúrgica nos llevan a plantear la relevancia actual de dicha clasificación. Métodos: Se realizó una revisión retrospectiva de los pacientes operados de meningiomas grado I entre Febrero de 2006 y Diciembre de 2015. Se analizaron las imágenes pre y postoperatorias y la anatomía patológica. Las variables se relacionaron mediante un análisis estadístico multivariado estableciendo como estadísticamente significativo una P < 0.05. Resultados: No se objetivó una diferencia estadísticamente significativa entre el número de recidivas y el grado de resección tumoral según Simpson I, II, III o IV (P = 0,3117). Esto puede afirmarse para los grados Simpson I y II en donde el número de pacientes incluidos en la muestra (n) fue alto. Al analizar como factor de recurrencia la localización tumoral tampoco se encontró una diferencia significativa en cuanto al porcentaje de recidivas entre aquellos tumores localizados en la convexidad, base de cráneo y parasagitales (P = 0,2203). Conclusión: Para los meningiomas grado I la exéresis Simpson I no presenta diferencias significativas con la Simpson II en cuanto a la recurrencia tumoral, por lo que aumentar la morbilidad del procedimiento no tendría justificación. Un replanteo de la escala de resección debería idearse teniendo en cuenta la clasificación de la OMS. PMID:29142775

To investigate the knowledge of adolescents related to sexually transmitted infections (STIs), AIDS, and pregnancy, and understand the role of school in sex education. A qualitative descriptive study, developed through a semi-structured interview and a form for participant characterization, with 22 high school students from a public school aged 16 to 19 years. Data were submitted to content analysis. After analysis, four thematic categories were developed: sexuality and sex education; understanding of risk behaviors; knowledge of STI/AIDS; and knowledge of and practices for prevention. This study showed the need for preventive educational actions for adolescents, because the lack of information contributes to their vulnerability. The adolescents recognize the importance of sex education; therefore it is important to implement strategies to promote and protect health in the school environment to encourage and strengthen self-care in health. investigar o conhecimento de adolescentes relacionado às Infecções Sexualmente Transmissíveis (IST), AIDS e gravidez, além de conhecer a compreensão sobre o papel da escola na educação sexual. estudo qualitativo, descritivo, desenvolvido por meio de entrevista semiestruturada e formulário para caracterização dos participantes, com 22 adolescentes entre 16 e 19 anos de idade, estudantes do Ensino Médio em uma escola pública.

A watershed-scale approach to tracing metal contamination in the environment
Church, Stanley E
1996-01-01
watersheds in the western U.S. A different approach to the scope of the abandoned mine problem (Church et al., 1996a) is shown by the water quality data collected by the States under the Clean Water Act, section 305(b). These data document the stream reaches affected by metals from naturally occurring sources as well as from mining, or mineral resource extraction. Permitted discharges from active industrial and mine sites are not covered in the 305(b) data base.Local citizens and state and federal agencies are all part of the collaborative decision process used to select the drainage basins chosen for the AML Initiative pilot studies. Data gathered by these three entities were brought to bear on the watershed selection process. The USGS prepared data available from Federal data bases in the form of interpretative GIS products. Maps of the states of Colorado (Plumlee et al., 1995) and a similar study of the state of Montana (USGS, unpublished data) were used to select the Animas watershed in southwestern Colorado and the Boulder watershed southwest of Helena Montana as the pilot study areas for the AML Initiative. Thus, the watersheds selected for study were public decisions made on the basis of available scientific data. The role of the U.S. Geological Survey in the Abandoned Mine Land Initiative is outlined in Buxton et al. (1997).The watershed approach to metals contamination in the environment has been studied in several drainage basins (Church et al., 1993, 1994, 1995, 1996b; Kimball et al., 1995). The underlying principles used to successfully discriminate between sources and to quantify the impact of these sources on the environment are the subject of this report.

To identify the association between blood pressure control and the following variables: a) bio-social and lifestyle characteristics of hypertensive patients; and b) factors related to the antihypertensive treatment. This is an exploratory study with 290 people with hypertension from primary care. We used a specific instrument, self-administered, with 21 questions on factors that can hinder treatment, divided into four dimensions: medication, socioeconomic, institutional and personal beliefs. We adopted a significance level of p <0.05. The control of blood pressure was associated (p <0.05) with female gender, Caucasian ethnicity, primary/secondary education, not drinking alcohol, higher income and regular physical activity. Regarding the factors that can hinder treatment, there was association of hypertension control with only two questions: "feel nothing" and "have to do treatment for life". Sociodemographic variables and beliefs concerning the absence of symptoms and chronicity of the disease influenced the control of hypertension and should be considered in the adherence process to the treatment. Identificar a associação entre o controle da pressão arterial e as seguintes variáveis: a) características biossociais e hábitos de vida dos hipertensos; e b) fatores relacionados ao tratamento anti-hipertensivo. Realizou-se estudo exploratório com 290 hipertensos da atenção primária. Utilizou-se de instrumento específico, autoaplicável, com 21 questões sobre fatores que podem dificultar o tratamento, divididas em quatro domínios: medicamentos, socioeconômico, institucional e crenças pessoais. Adotou-se nível de significância de p < 0,05. O controle da pressão arterial se associou (p < 0,05) com sexo feminino, etnia branca, ensino fundamental/médio, não ingerir bebida alcoólica, maior renda e atividade física regular. Quanto aos fatores que podem dificultar o tratamento, houve associação do controle com apenas duas questões: "não sentir nada" e

To characterize cancellations of elective surgeries according to clinical and non-clinical reasons, as well as to verify seasonal influence and determine the estimated reduction of the index. Quantitative, descriptive and retrospective study with secondary data extracted from the Public Hospital of the State of São Paulo database. Out of the 8,443 (100%) elective surgeries scheduled, 7,870 (93.21%) were performed and 573 (6.79%) were canceled. Out of these 573 (100%) people, 48.33% were canceled for clinical reasons and 46.40% were for non-clinical reasons. Among the non-clinical reasons for surgery cancellations, those related to medical reasons stood out: at the request of the surgeon/change of approach (17.93%), followed by non-hospitalized patient (8.96%). There was no indication of seasonality regarding the reasons for cancellation in the assessed period. Although the rate of elective surgeries cancellations is lower than that of other hospitals with similar characteristics, it is still possible to reduce it from 6.79% to 1.36%, considering that 80% of the reasons for cancellation are avoidable. Caracterizar cancelamentos cirúrgicos eletivos segundo motivos clínicos e não clínicos, assim como verificar a influência sazonal e a estimativa de redução do índice. Estudo quantitativo, descritivo e retrospectivo com dados secundários, extraídos de banco de dados de Hospital Público do Estado de São Paulo. Das 8.443 (100%) cirurgias eletivas agendadas, realizaram-se 7.870 (93,21%) e suspenderam-se 573 (6,79%). Destas 573 (100%), 48,33% foram por razões clínicas e 46,40% não clínicas. Dentre os motivos não clínicos de cancelamento cirúrgico, preponderaram os relacionados às razões médicas, categorizadas como: a pedido do cirurgião/mudança de conduta (17,93%), seguida por paciente não internou (8,96%). Não houve indicação de sazonalidade quanto à ocorrência de motivos de cancelamento no período analisado. Apesar de a taxa de cancelamento

Devido a constante necessidade de miniaturizacao, reducao de custos e maior funcionalidade e integracao, a tecnologia de filmes espessos esta a tornar-se uma abordagem de processamento de materiais funcionais cada vez mais importante. Uma tecnica adequada neste contexto e EPD. Os filmes espessos resultantes necessitam de um passo subsequente de sinterizacao que e afectada pelo substrato subjacente, tendo este um forte efeito sobre a evolucao da microestrutura. Relacionado com a miniaturizacao e a discriminacao do sinal, materiais dielectricos usados como componentes operando a frequencias das microondas em aplicacoes na industria microelectronica de comunicacoes devem apresentar baixas perdas dielectricas e elevadas permitividade dielectrica e estabilidade com a temperatura. Materiais do sistema BaO-Ln2O3- TiO2 (BLnT: Ln = La ou Nd), como BaLa4Ti4O15 (BLT) e Ba4.5Nd9Ti18O54 (BNT), cumprem esses requisitos e sao interessantes para aplicacoes, por exemplo, em estacoes de base para comunicacoes moveis ou em ressonadores para telefones moveis, onde a miniaturizacao dos dispositivos e muito importante. Por sua vez, o titanato de estroncio (SrTiO3, STO) e um ferroelectrico incipiente com constante dielectrica elevada e baixas perdas, que encontra aplicacao em, por exemplo, condensadores de camada interna, tirando partido de
Innovation in healthcare services: notes on the limits of field research.

The contemporary context of population aging, itsthe population's different health and disease characteristics, and the growing incorporation of technologies by healthcare systems have highlighted the need to adjust the healthcare structure as a whole. The defense of a democratic and sustainable system reveals the importance of understanding how changes in healthcare take place. The current article aims to contribute to the understanding of innovation in healthcare services. The study's results indicate that the existence of certain knowledge gaps means that public policies tend to overlook a whole rangeseries of innovations normally associated with social changes, with a consequentwith an impact on human development, social cohesion, equality, and equity, allcentral issues that are central toin the field of collective public healthcare field. The article concludes that the lack of a mature theoretical framework negatively impacts the formulation of such policies, further aggravated in Brazil by growing differences in quality and access between population segments that depend on the public and private healthcare systems. Resumo: O contexto contemporâneo de envelhecimento e as características de saúde e doença da população, aliados à crescente incorporação tecnológica nos sistemas de saúde têm pontuado a necessidade de adequação da estrutura de atenção. A defesa de um sistema democrático e sustentável evidencia a importância de entender como são estabelecidos os processos relacionados às mudanças na saúde. Neste cenário, o presente artigo visa aprofundar o entendimento sobre inovação nos serviços de saúde. Os resultados da pesquisa indicaram que lacunas no conhecimento levam políticas públicas a negligenciarem uma série de inovações normalmente associadas a mudanças sociais com impacto no desenvolvimento humano, coesão social, igualdade e equidade, temas centrais ao campo da saúde coletiva. E conclui que a falta de um referencial

Deglaciation and postglacial treeline fluctuation in the northern San Juan Mountains, Colorado
Carrara, Paul E.
2011-01-01
The San Juan Mountains of southwestern Colorado contain numerous lakes and bogs at and above treeline. In June 1978, Lake Emma, a tarn above present-day treeline, was suddenly drained by the collapse of underground mine workings. This study was initiated because the draining exposed a well-preserved archive of subfossil coniferous wood fragments that provided a unique opportunity to further our understanding of the paleoclimatic history of this region. These paleoclimatic studies-coniferous macrofossil identification in conjunction with radiocarbon dating, deuterium analysis of the dated conifer fragments, as well as pollen and fossil insect analyses-yielded new information regarding Holocene climate and accompanying treeline changes in the northern San Juan Mountains. This report synthesizes previously published reports by the author and other investigators, and unpublished information of the author bearing on late Pleistocene and Holocene treeline and climate in this region. Retreat of the glacier that occupied the upper Animas River valley from its Pinedale terminal position began about 19.4 + or - 1.5 10Be thousands of years ago and was essentially complete by about 12.3 + or - 1.0 10Be thousands of years ago. Two sets of late Pleistocene cirque moraines were identified in the northern San Juan Mountains. The older set is widespread and probably correlates with the Younger Dryas (11,000-10,000 radiocarbon years before present; 12,800-11,500 calendar years). The younger set is found only in the Grenadier Range and represents remnant glacier ice lying in well-shaded niches in a mountain range undergoing rapid deglaciation. A snowbank at the northern base of this range appears to be fronted by a Little Ice Age moraine. Soon after deglaciation the average July temperature is estimated to have been about 5°C cooler and timberline about 650 meters lower than at present. However, timberline (and treeline) responded rapidly to the postglacial warming and reached

that grow principally on or below the surface of the water; (2) Moss-Lichen Wetland, dominated by mosses or lichens; (3) Emergent Wetland, dominated by emergent herbaceous angiosperms; (4) Scrub-Shrub Wetland, dominated by shrubs or small trees; and (5) Forested Wetland, dominated by large trees.The Dominance Type, which is named for the dominant plant or animal forms, is the lowest level of the classification hierarchy. Only examples are provided for this level; Dominance Types must be developed by individual users of the classification.Modifying terms applied to the Classes or Subclasses are essential for use of the system. In tidal areas, the type and duration of flooding are described by four Water Regime Modifiers: subtidal, irregularly exposed, regularly flooded, and irregularly flooded. In nontidal areas, eight Regimes are used: permanently flooded, intermittently exposed, semipermanently flooded, seasonally flooded, saturated, temporarily flooded, intermittently flooded, and artificially flooded. A hierarchical system of Water Chemistry Modifiers, adapted from the Venice System, is used to describe the salinity of the water. Fresh waters are further divided on the basis of pH. Use of a hierarchical system of soil modifiers taken directly from U.S. soil taxonomy is also required. Special modifiers are used where appropriate: excavated, impounded, diked, partly drained, farmed, and artificial.Regional differences important to wetland ecology are described through a regionalization that combines a system developed for inland areas by R. G. Bailey in 1976 with our Marine and Estuarine provinces.The structure of the classification allows it to be used at any of several hierarchical levels. Special data required for detailed application of the system are frequently unavailable, and thus data gathering may be prerequisite to classification. Development of rules by the user will be required for specific map scales. Dominance Types and relationships of plant and anima

The year 2004 signals the 400th anniversary of the birth of count Mauricio of Nassau, an important character in the history of Brazil. The present text is related to the period of Dutch domination in Pernambuco. The article attempts to rescue the beginnings of Astronomy study in the South hemisphere. Therefore, we idealized a dramatization of a fictitious interview with German astronomer Georg Marcgrave, who was the constructor of the first astronomical observatory in this hemisphere and the author of the first systematic astronomical observations using telescopes in this side of the world. Our "conversation" with Marcgrave is idealized in the old Recife scenario, a place where he lived in Mauricio of Nassau's period and gathers some fellow teachers who love the teaching of Astronomy. The story, this way, is reported in a possibly light and funny atmosphere. Nevertheless, the conceptual and historical framework presented is based on reliable bibliographical sources pointed out at the end of the text. The sources range from the original book of that scientist, in which a solar eclipse is reported, passing through some other classical texts, such as that of Professor Juliano Moreira, up to more recent sources such as the very influential work of professor John North. Other influential texts about the Dutch period in Brazil, such as the classical works of Charles Boxer, Bouman and Boogaart, among others, are also used in the construction of this pedagogical dramatization, which involves an interesting chapter of the history of Astronomy. El año 2004 marca los 400 años del nacimineto del conde Mauricio de Nassau, un importante personaje de la historia del Brasil.

To understand experiences in the development of communication skills and the teacher's role in this teaching-learning process under the perspective of undergraduate nursing students by considering two types of curriculum organization. Descriptive study with a qualitative approach conducted in two public schools located in São Paulo state, Brazil. Data were collected by means of self-completed forms from 81 students in the second and fourth years of the undergraduate program. Results were analyzed in light of Content Analysis. Results showed that the development of such skills is related to: students' individual characteristics, patients' characteristics, those of the health-disease process, the health-care team's profile and the theoretical knowledge acquired on communication in health-care provision and nursing. The teacher's role was perceived as one that supports and encourages interactions with patients and health-care teams by teaching and providing orientation about interpersonal communication. Students identify and value the importance of their teachers' performance in the development and acquisition of communication skills. Additionally, students who experience active teaching-learning methodologies acknowledge the teacher as essential to provide opportunities for students to express their knowledge and thoughts.

Build conceptual definitions for some indicators of the nursing outcome Infection Severity in the Nursing Outcomes Classification (NOC) related to respiratory problems, based on scientific evidence of signs and symptoms of infection in adults. Integrative literature review with search in the databases PubMed, CINAHL, LILACS and SCOPUS. Studies whose full texts were available, published in Spanish, Portuguese or English, using the descriptors infection severity, nursing outcomes classification NOC, respiratory infections and respiratory signs and symptoms. Nine publications were analyzed that supported the elaboration of the conceptual definitions for eight indicators of the Nursing Outcome Infection Severity: purulent drainage, fever, chilling, unstable temperature, pain, colonization of drainage cultivation, white blood cell count elevation and white blood cell count drop. This study contributed to understand the terms used in the nursing outcome Infection Severity, in order to improve and facilitate the use of the NOC, as it enhances the conceptual clarity of the selected indicators with a view to producing better scientific evidence.Objetivo.Construir definições conceituais para alguns indicadores do resultado de enfermagem Gravidade de Infecção da Nursing Outcomes Classification (NOC) relacionados aos problemas respiratórios, a partir de evidências científicas sobre sinais e sintomas de infecção em pessoas adultas.

Vaz, Nuno Alexandre Firmino
O principal objectivo deste trabalho consistiu no estudo da dinâmica termohalina do Canal do Espinheiro em funcao de dois forcamentos principais: mare e caudal fluvial, usando duas abordagens distintas: trabalho experimental e modelacao numerica. A propagacao da mare e o caudal fluvial do Rio Vouga sao determinantes no estabelecimento da estrutura horizontal da salinidade ao longo do canal. A estrutura termica horizontal ao longo do canal e, em grande parte, determinada pela variacao sazonal da temperatura da agua do Rio Vouga, bem como, pela variacao sazonal das condicoes meteorologicas devido a reduzida profundidade. Foi observada a formacao de fortes gradientes de salinidade (relacionados com a formacao de frentes estuarinas) numa regiao a cerca de 7-8 km da embocadura do canal, observando-se a sua migracao numa regiao de aproximadamente 1 km, dependendo do regime de mare. O balanco entre o transporte de sal de natureza advectiva e difusiva foi calculado, revelando que junto a embocadura os processos fisicos que mais contribuem para o transporte de sal sao a circulacao residual e o aprisionamento da agua em canais secundarios. Junto a foz do Rio Vouga os termos devidos a descarga fluvial e a circulacao gravitacional dominam o transporte de sal. Foi calibrado e validado um modelo numerico (Mohid, em modo 2D e 3D), sendo posteriormente utilizado para estudar a hidrologia do canal. Foi concedida particular atencao ao estudo da hidrologia em condicoes extremas de caudal fluvial e de mare. Os resultados da modelacao numerica permitiram numa primeira fase avaliar o bom desempenho do Mohid na reproducao dos escoamentos barotropicos na Ria de Aveiro, bem como na evolucao temporal das propriedades termohalinas da agua. Sob condicoes de caudal fluvial reduzido, a dinâmica do canal e essencialmente dominada pela mare. Com o aumento do caudal fluvial, a influencia da agua doce estende-se para jusante, estratificando a coluna de agua. As simulacoes 3D do Canal do

Bariatric surgery is considered the most effective tool in the control and treatment of severe obesity, but patients undergoing this procedure are at increased risk of developing nutritional deficiencies by limiting the intake and absorption of many nutrients. To assess the impact of vitamin D deficiency and calcium in bone in patients after gastric bypass in Roux-en-Y, pointing directly at the type of administration, doses and effects after surgery. Was conducted a systematic review with articles related to the topic of the last 10 years searched in PubMed (US National Library of Medicine National Institutes of Health, Medline, Lilacs, Scielo and Cochrane using the headings "bariatric surgery", "bone", "obesity", "vitamin D '', "calcium" AND "absorption". Exclusion criteria to research on animals, smokers, pregnant women and patient treated with bisphosphonates. Five articles were included in this review. All refer that bariatric surgery can lead to nutritional deficiencies and poor absorption of fats and fat-soluble vitamins and other micronutrients such as calcium. Patients submitted to RYGB should make use of multivitamins and minerals especially vitamin D and calcium to prevent bone fractures. Monitoring, treatment and control of risk factors are essential to prevent complications after this operation.

To assess aspects related to cancer in indigenous population. This is a retrospective study developed in a public university hospital. We included patients with 18 or more years of age, diagnosed with solid tumors, and followed between 2005 and 2015. Clinical features were assessed by descriptive statistics, and survival was evaluated by Kaplan-Meier curves and multivariate Cox regression. Fifty patients were included. The cancer incidence was 15.73 per 100,000. The mean age at diagnosis was 54 years and most patients were female (58%). Cancer of the cervix (28%) and prostate (16%) were the most common. The mean time between the onset of symptoms and the diagnosis was 9 months and from diagnosis to the treatment was 3.4 months. Disease diagnosed at stage IV (17%) had worse overall survival (HR: 11.4; p<0.05). The 5-year survival rate ranged from 88% for prostate cancer to 0% for lung cancer. All 5-year survival rates were lower as compared to other populations. The most prevalent cancer sites were cervix and prostate. Disease stage and primary site were prognostic factors.

enfocan más en los conductores del comportamiento humano y en las implicaciones de varias fuentes de incertidumbre en la toma de decisiones de manejo. La cacería de trofeos ha sido sugerida como una herramienta de conservación porque le otorga valor económico a la vida silvestre, pero ejemplos recientes muestran que la sobrecolecta es un problema sustancial y que las limitaciones de datos son abundantes. Usamos el estudio de caso de la cacería de trofeos de un antílope en peligro, el nyala de las montañas (Tragelaphus buxtoni), para explorar como las incertidumbres generadas por el monitoreo de poblaciones y el tráfico de especies interactúan con la toma de decisiones de 2 actores clave: las compañías de safari y el gobierno. Construimos un modelo de evaluación de estrategia de manejo que incluye la dinámica poblacional del nyala de las montañas, un modelo de monitoreo y un modelo de toma de decisiones de una compañía. Investigamos escenarios de inversión en el combate del tráfico de especies y el monitoreo por el gobierno y las compañías de safari. La estrategia de colecta fue robusta hacia la incertidumbre en los estimados de población obtenidos del monitoreo, pero el tráfico de especies tuvo un efecto más fuerte sobre la cuota y la sustentabilidad; por esto, reducir el tráfico de especies está dentro de los intereses de compañías que desean incrementar la rentabilidad de las empresas, por ejemplo al hacer participar a los miembros de la comunidad como guías de caza. Hay un nivel umbral de incertidumbre en los estimados de población más allá del cual la variación anual en la cuota de trofeos previene la planeación por parte de las compañías de safari. Esto sugiere un papel para el gobierno asegurando que un nivel base de monitoreo de población se lleve a cabo para que este nivel no sea excedido.

Desde cedo que a comunidade cientifica compreendeu que gases nobres em liquido sao excelentes meios de deteccao de radiacao, combinando a sua elevada densidade, elevado grau de homogeneidade e de elevado rendimento de cintilacao. Para alem destas caracteristicas inerentes, estes tem a potencialidade de fornecer ambos sinais de ionizacao - criando electroes livres - e cintilacao em resposta a interaccao com radiacao ionizante e, tendo em vista a sua aplicacao em experiencias de eventos raros relacionados com fisica de neutrinos ou materia-escura, a capacidade de autoblindagem garante a exclusao de eventos induzidos por radiacao de fundo. O facto de nao absorverem a sua propria luz, emergente dos eventos de cintilacao, permite a expansao deste tipo de detectores ate grandes volumes, sendo que as colaboracoes mais recentes propoem detectores com dezenas de toneladas de xenon em estado liquido. As experiencias actuais que usam gases nobres em estado liquido empregam xenon ou argon numa so fase (estado liquido) ou em dupla-fase (estado liquido + gasoso) e as suas aplicacoes abrangem desde as ja referidas experiencias de procura de eventos raros, passando por imagiologia medica tais como detectores de radiacao gama para PET ou câmaras Compton "3-gamma" em combinacao com PET, passando tambem por aplicacoes de seguranca como sistemas de inspeccao para deteccao de material fissil e, finalmente, em câmaras Compton para aplicacoes de astrofisica. Em ambas as configuracoes a leitura dos sinais de cintilacao e geralmente feita atraves de um grande numero de dispendiosos fotomultiplicadores de vacuo agrupados. A presente tese de doutoramento e dedicada aos fotomultiplicadores gasosos de grande area para aplicacoes criogenicas desenvolvidos no contexto do programa doutoral, tendo em vista a sua eventual aplicacao como um dispositivo complementar aos metodos existentes de deteccao de cintilacao, para aplicacao em futuras experiencias de grande escala.

ça. O estresse mecânico sobre os tendões parece ser um dos mais importantes na promoção do processo inflamatório inicial. Todavia não é o único. Existem fatores ambientais, genéticos e metabólicos atuando de maneira ativa. Portanto, as tendinopatias em indivíduos obesos podem se dever à sobrecarga mecânica pelo excesso de peso, mas, também, pelo aumento na produção de mediadores pró-inflamatórios relacionados ao tecido adiposo, como as adipocinas. O estado pró-inflamatório existente no indivíduo obeso é conhecido como adiposopatia ou síndrome da "gordura doente". A perda de peso está associada com decréscimo das adipocinas e diminuição da sintomatologia musculoesquelética. A associação da obesidade com tendinopatias tem sido fundamentada em estudos recentes como os desta revisão de literatura.

Studies related to obesity have shown association with metabolic syndrome. Data showing that obesity is capable to cause low grade chronic inflammation, without its classic signs and symptoms, call attention to researches to study different cells types and the mechanism of the inflammatory process. To evaluate the variation of glycated hemoglobin (HbA1c) and the pro-inflammatory cytokine interleukin-6 (IL6) in diabetic patients with BMI <35 kg/m2 in the pre and postoperative of partial duodenal switch. Nine patients were studied before and one year after the operation and the variation of the serum IL6 was measured by Elisa. The changes of HbA1c were also registered. The pre-operative IL6 levels reached 65,50436±2,911993 pg/ml and one year after de operation 39,47739±3,410057 and the HbA1c average of 10,67 and 5.8 in the same period. The partial duodenal switch was efficient to control one year after the procedure the chronic inflammatory process caused by the diabetes mellitus type 2 with BMI <35 by dropping the IL6 levels and bringing the HbA1c to normal. Os estudos relacionados à obesidade têm evidenciado sua associação com a síndrome metabólica. A descoberta que a obesidade é capaz de promover inflamação, sem os sinais clássicos, tem levado vários grupos de pesquisa a caracterizar os tipos celulares que agem e o mecanismo envolvido neste processo. Avaliar a variação da hemoglobina glicada e a secreção da citocina inflamatória, interleucina-6, em indivíduos diabéticos com IMC<35 kg/m² no pré e pós-operatório da técnica de desvio duodenal parcial. Nove pacientes foram avaliados antes e um ano após a operação e a variação da concentração da interleucina-6 foi avaliada pela metodologia de Elisa. Também foi avaliada a variação da HbA1c. A quantificação de interleucina-6 apresentou no pré-operatório valor de 65,50436±2,911993 pg/ml e de 39,47739+3,410057 pg/ml após um ano da operação e a hemoglobina glicada apresentou m

de cinco anos bajo el proyecto de Investigacion Coordinada (PIC) sobre 'el Aseguramiento de la Calidad de Moscas de las Frutas Criadas y Liberadas para su Uso en Programas de TIE'. Los participantes en el PIC representan 16 paises con experiencia en campos de investigacion basica y aplicada. Para asegurar que los procedimientos desarrollados fueran apropiados y pertinentes, se realizaron una variedad de estudios para el desarrollo de protocolos para evaluar la compatibilidad y para mejorar los procedimientos de colonizacion y manejo de cepas salvajes. Estudios especificos trataron asuntos relacionados con la nutricion de insectos, los protocolos de irradiacion, la dispersion y supervivencia en el campo, evaluacion del comportamiento en jaulas de campo, y el mejoramiento de la competitividad sexual. Los objetivos fundamentales fueron el aumentar la eficiencia y reducir los costos de los programas operacionales de control de moscas de las frutas donde TIE es utilizada. Muchos de los protocolos desarrollados o mejorados durante el PIC seran incorporados en el Manual Internacional de Control de Calidad para Moscas Estriles de la familia Tephritidae, para estandarizar componentes claves como la produccion, esterilizacion, envio, manejo y liberacion de insectos esteriles.

ões de reais no ano de 2015, um aumento percentual de 17% no período de 2010 a 2015. Os custos estimados pela morte prematura por DCV representam 61% do total de custo por DCV, os custos diretos com internações e consultas foram de 22% e os custos pela perda da produtividade relacionados à doença foram de 15% do total. Os gastos com saúde no Brasil são estimados em 9,5% do PIB e o custo médio das DCV foi estimado em 0,7% do PIB. Os custos com DCV vêm aumentando significativamente nos últimos cinco anos. Estima-se que os custos por DCV aumentem à medida que a população brasileira envelhece e que a prevalência de DCV aumenta.

A Engenharia de Tecidos e uma area cientifica em continua expansao. Os desenvolvimentos conseguidos por esta area tem contribuido significativamente para diversos avancos no campo da Medicina Regenerativa. Esta ciencia interdisciplinar combina os conhecimentos de diversas outras areas, tao distintas como a Engenharia de Materiais e a Biologia, com o objectivo de desenvolver substitutos sinteticos para tecidos humanos. Para se atingir este objectivo utilizam-se, de uma forma generica, combinacoes especificas de celulas e de um material de suporte tridimensional com propriedades adequadas, gerando um material hibrido cujas caracteristicas podem ainda ser moduladas atraves do sistema de cultura usado. A presente tese e centrada no desenvolvimento de estrategias de engenharia de tecido osseo baseadas na cultura in vitro de celulas previamente "semeadas" num suporte tridimensional ("scaffold"). Esta estrategia permite que as celulas adiram ao suporte, proliferem e segreguem matriz extracelular especifica do tecido osseo, ate se obter um substituto artificial funcional com caracteristicas do tecido original, que pode finalmente ser transplantado para tratar o defeito em causa. Para que uma estrategia deste tipo seja bem sucedida, pelo menos tres componentes fundamentais devem ser cuidadosamente estudados: o material de suporte (scaffold), as celulas a usar e o sistema de cultura in vitro. Dai que os principais objectivos desta tese estejam relacionados com estes tres aspectos, nomeadamente: • Desenvolvimento de scaffolds biodegradaveis a partir de polimeros a base de amido de milho que induzam a adesao e proliferacao celular e que apresentem propriedades adequadas, tais como a porosidade e interconectividade entre poros, de forma a proporcionar um ambiente que favoreca o desenvolvimento in vitro de um material hibrido com caracteristicas similares ao osso humano. • Estudo da utilizacao de celulas da medula ossea como uma potencial fonte de celulas para engenharia do

The oxidative biomarkers play an important role in the genesis of cardiometabolic risk-related processes. To investigate the total antioxidant capacity of plasma and its association with cardiometabolic risk in non-obese and clinically healthy young adults. University students of the state of Sergipe, Brazil, aged between 18 and 25 years, were recruited for this study from May of 2013 and October of 2014. Anthropometric, clinical and biochemical parameters were measured and analyzed using protocols which were previously standardized and described in the literature. The measurement of plasma total antioxidant capacity was based on the ability that all the antioxidants present in the sample (plasma) have to inhibit the oxidation of the oxidizable substrate ABTS (2,2`- Azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS•+ by metmyoglobin. Approximately 25% of the sample presented more than one component of cardiometabolic risk. Low HDL-cholesterol was the most prevalent component. Compared to absence of components, the subjects with at least one component presented greater body weight and waist circumference, higher levels of diastolic blood pressure and fasting glucose, greater total cholesterol/HDL-c ratio, and lower levels of HDL-c (p < 0.05). Fasting glycemia was the only parameter which was associated with total antioxidant capacity (R2 = 0.10; β = 0.17; p = 0.001). The plasma total antioxidant capacity was not able to predict the cardiometabolic risk components due possibly to the establishment of compensatory mechanisms that become activated in physiological conditions. Os biomarcadores oxidativos exercem um importante papel na gênese dos processos relacionados ao risco cardiometabólico. Investigar a capacidade antioxidante total do plasma e sua associação com risco cardiometabólico em adultos jovens, não obesos e clinicamente saudáveis. Estudantes universitários do estado de Sergipe, Brasil, com idade entre 18 e 25 anos, foram recrutados entre maio

Bariatric surgery has been an alternative when conservative methods of weight loss fail. Patients undergoing bariatric surgery have an increased risk of up to 6.5% of problems related to alcohol. Integrative review out to analyze the change of alcohol consumption in this public. Database was accessed from June of 2015 to January of 2016 by searching "bariatric surgery" AND "alcoholism", and their Portuguese equivalents. ScienceDirect, PubMed, Lilacs and Medline, besides manual search, were searched. To be included, the paper should have been published between 2005-2016 and related to bariatric surgery and alcoholism. Theses, dissertations, unpublished papers, case reports and theoretical studies were excluded, and a database was subsequently composed. In 2005 there was only a review of change in alcohol metabolism in patients undergoing bariatric surgery. There were no publications in 2006. In 2007, only one study was published, and it did not meet the inclusion criteria. In 2010, there was an increase of 13% in publications and of 20% in 2012, reaching 40% in 2013. The prevalence and incidence of alcohol consumption in relation to the postoperative time was six months to three years with higher incidence for follow-up treatment by men. Roux-en-Y gastric bypass showed greater association with increased consumption of alcohol during the postoperative period. Alcohol consumption proved to be essential to be faced in bariatric surgery. A cirurgia bariátrica tem-se mostrado alternativa para o insucesso dos métodos conservadores de emagrecimento. Pacientes submetidos a ela têm 6,5% aumento do risco de terem problemas relacionados ao álcool. Realizar revisão integrativa para verificar alteração do consumo de álcool neste publico.

concerne a carga e as caracteristicas gelificantes: a goma de alfarroba (nao ionica), o quitosano (cationico) e a goma xantana (anionica) cujas propriedades reologicas sao amplamente conhecidas. Os estudos reologicos realizados sob diferentes condicoes demonstraram que a formacao de geis frageis e/ou bem estruturados depende do tamanho SiO2, da concentracao, do pH e da forca ionica. Estes estudos foram confirmados por analises microestruturais usando a microscopia electronica a baixas temperaturas (Cryo-SEM). No quarto capitulo, sao apresentados os estudos relativos a preparacao e caracterizacao de filmes bionanocompositos utilizando quitosano como matriz. Primeiramente e apresentada uma revisao sobre filmes de bionanocompositos e os aspectos fundamentais das tecnicas de caracterizacao utilizadas. A escolha do plasticizante e da sua concentracao sao discutidas com base nas propriedades de filmes de quitosano preparados. Em seguida, o efeito da concentracao de silica e dos metodos utilizados para a dispersar na matriz de polissacarideo, bem como o efeito da modificacao da superficie da silica e avaliado. As caracteristicas da superficie e as propriedades de barreira, mecanicas e termicas sao discutidas para cada conjunto de filmes preparados antes e apos a sua neutralizacao. Os resultados obtidos mostraram que a dispersao das cargas no plasticizante e posterior adicao a matriz polissacaridica resultaram apenas em pequenas melhorias ja que o problema da agregacao de silica nao foi ultrapassado. Por esse motivo foram preparados filmes com SiO2 APS os quais apresentaram propriedades melhores apesar da agregacao das particulas nao ter sido completamente impedida. Tal pode estar relacionado com o processo de secagem dos filmes. Finalmente, no capitulo 5, sao apresentadas as principais conclusoes obtidas e algumas sugestoes para trabalho futuro.

condutividade num composito reforcado com nanofibras de carbono pode ser descrito por uma rede de Bethe. Atraves do uso da teoria das redes complexas, chegou-se a uma expressao para o limite de percolacao e, do mesmo modo, demonstrou-se que “hopping” entre fibras adjacentes resulta numa expressao que corresponde a um regime de desordem fraca. No trabalho desenvolvido tambem foi calculado os expoentes criticos, atraves da teoria das redes, para um sistema 3D composto por cilindros impenetraveis com uma interacao de curto alcance, demonstrando que os expoentes criticos estao relacionados por uma relacao de hiperescala comum para 3D e nao pertencem a mesma classe de universalidade como a percolacao numa rede. A aplicacao do modelo desenvolvido a compositos de epoxy reforcada, com diferentes metodos de dispersao de nanofibras de carbono, revelou que os metodos de dispersao usados para preparar os compositos tem uma forte influencia nas propriedades eletricas que podem ser capturadas pelo modelo. Neste contexto, ficou ainda demonstrado que a condutividade eletrica pode ser descrita por um regime de desordem fraca, isto ´e, um regime onde todas as conexoes fibra-fibra participam na condutividade do composito. O modelo desenvolvido foi aplicado igualmente a compositos de poly (vinylidene fluoride) reforcado com nanotubos de carbono com diferentes tratamentos de termicos de oxidacao. Verificou-se que os tratamentos de superficie aumentam o limite de percolacao e diminuem a condutividade. Nesta dissertacao provamos ainda que a condutividade do composito pode ser atribuida a um mecanismo de “hopping”, fortemente afetado pelos tratamentos de superficie dos reforcos.

submetida à investigação clínica e genética. As regiões codificadoras dos genes MYH7, MYBPC3 e TNNT2 foram sequenciadas e analisadas. O probando apresenta uma manifestação maligna da doença e é o único em sua família a desenvolver CMH. A análise genética pelo sequenciamento direto dos três principais genes relacionados à essa doença identificou uma variante em heterozigose composta (p.E542Q e p.D610H) em MYBPC3. A análise da família mostrou que os alelos p.E542Q e p.D610H tem origem paterna e materna, respectivamente. Nenhum familiar portador de um dos alelos variantes manifestou sinais clínicos de CMH. Sugerimos que a expressão heterozigótica bialélica de p.E542Q e p.D610H pode ser responsável pelo fenótipo severo da doença encontrada no probando.

To describe diagnostic and treatment aspects of hard metal lung disease (HMLD) and to review the current literature on the topic. This was a retrospective study based on the medical records of patients treated at the Occupational Respiratory Diseases Clinic of the Instituto do Coração, in the city of São Paulo, Brazil, between 2010 and 2013. Of 320 patients treated during the study period, 5 (1.56%) were diagnosed with HMLD. All of those 5 patients were male (mean age, 42.0 ± 13.6 years; mean duration of exposure to hard metals, 11.4 ± 8.0 years). Occupational histories were taken, after which the patients underwent clinical evaluation, chest HRCT, pulmonary function tests, bronchoscopy, BAL, and lung biopsy. Restrictive lung disease was found in all subjects. The most common chest HRCT finding was ground glass opacities (in 80%). In 4 patients, BALF revealed multinucleated giant cells. In 3 patients, lung biopsy revealed giant cell interstitial pneumonia. One patient was diagnosed with desquamative interstitial pneumonia associated with cellular bronchiolitis, and another was diagnosed with a hypersensitivity pneumonitis pattern. All patients were withdrawn from exposure and treated with corticosteroid. Clinical improvement occurred in 2 patients, whereas the disease progressed in 3. Although HMLD is a rare entity, it should always be included in the differential diagnosis of respiratory dysfunction in workers with a high occupational risk of exposure to hard metal particles. A relevant history (clinical and occupational) accompanied by chest HRCT and BAL findings suggestive of the disease might be sufficient for the diagnosis.

The Arkansas River is an important municipal water supply and is the primary supply for about 400,000 acres of irrigated land in southeastern Colorado. The suitability of this water for domestic, agricultural, and industrial use is affected by high salinity in parts of the Arkansas River. There is a need to quantify mass loading of dissolved solids (DS) in the Arkansas River. In 2009, the U.S. Geological Survey, in cooperation with the Arkansas River Basin Regional Resource Planning Group and the Colorado Water Conservation Board, began a study to estimate gains and losses from unmeasured sources and sinks for streamflow and DS load in selected reaches of the Arkansas River in southeastern Colorado. Two study reaches were selected for investigation—Canon City to just upstream from Pueblo Reservoir (UARB) and Avondale to Las Animas (LARB). The results from the water-budget analyses indicated that potential areas of unmeasured sources and sinks of streamflow were identifiable in the two study reaches. In the UARB, a substantial volume of water in the subreach from Ark at Canon City to the seasonal gaging station 5 miles downstream (Ark nr Canon City) was unaccounted for by the methodology used in this analysis. The daily gain from unmeasured sources in this subreach was estimated to be about 100 cubic feet per second (ft3/s) or about 20 ft3/s per river mile. Water-budget estimates for the remaining 18 miles of the UARB study reach indicated that gains or losses from unmeasured sources or sinks were within the measurement error as defined for this report. In the LARB, gains and losses from unmeasured sources and sinks were identified in some of the subreaches but the magnitude of the flux generally was small. Unmeasured sources ranging from less than 2 to 3 ft3/s per mile were identified in the river subreaches from Ark at Catlin Dam downstream to Ark at Swink. A streamflow loss was indicated along the subreach from Ark at Nepesta to Ark at Catlin Dam, particularly

in the paddy fields after harvesting and the straw is being as a residue that damages the air quality when burnt, the water quality due to the decomposition and the methane production, and is not accepted in the field by the farmers. This is a new problem as few years ago the rice straw was use for animal feeding. Many attempts were developed in the last decade to remove and use the straw to avoid fires and water pollution (Iranzo et al., 2004; Silvestre et al., 2013). Our goal is to test if a residue such as the rice straw can be transformed as a resource: soil erosion control. Straw has been seen as a very efficient to reduce the water losses in agriculture land (García Moreno et al., 2013), the soil losses in fire affected land (Robichaud et al., 2013a; 2013b; Fernandez and Vega, 2014), and soil properties (García Orenes et al., 2009; 2010; Jordán et al., 2010; García Orenes 2012). Rainfall simulations under 55 mm h-1 rainfall intensity during one hour on 0,25 m2 plots were carried out on plots paired plots: bare and covered with straw. The plots covered with straw had different straw mulch cover: from 10 to 100 % cover and from 0,005 g m2 to 300 g m2. The results show a positive effect of the straw cover that show an exponential relation between the straw cover and weight with the sediment yield.

O presente trabalho é parte preliminar de um estudo mais amplo em nível de doutorado sobre o ensino de astronomia mediado pelas tecnologias da informação e comunicação, utilizando dispositivos compactos, móveis e pessoais. Este estudo também faz parte do projeto institucional do CEFETMG sobre ambientes diversificados de aprendizagem sob fomento da agência estadual FAPEMIG (Fundação de Amparo à Pesquisa do Estado de Minas Gerais). Esta apresentação aborda o resultado das concepções prévias de estudantes em relação a conhecimentos básicos de astronomia, ligados à percepção e observação direta do céu. Três turmas de estudantes de 1ª série e uma turma de 3ª série do ensino integrado médio técnico da Educação Básica, Técnica e Tecnológica (EBTT) do CEFETMG Campus II - Belo Horizonte/MG foram submetidas a uma avaliação prévia através de questionário estruturado. Este questionário foi elaborado de forma a abordar a percepção dos estudantes em relação aos recursos gráficos (figuras e desenhos) representativos de conhecimentos básicos de astronomia, comuns em livros didáticos. Após a análise dos resultados desta avaliação, organizou-se uma estratégia de intervenção didática em sala de aula sobre o conteúdo de astronomia, utilizando-se de recursos de mediação baseados nas tecnologias da informação e comunicação. Os temas selecionados para esta estratégia didática foram relacionados aos assuntos básicos de astronomia em que ocorreu maior nível de desconhecimento dos estudantes. Os estudantes foram submetidos a avaliação posterior elaborada com os mesmos pressupostos da avaliação prévia. A análise dos resultados foi realizada a partir dos pressupostos da aprendizagem significativa (Ausubel; Novak e Hanesian, 1983). O ensino de astronomia por mediação das tecnologias da informação e comunicação indica uma alternativa preliminar aos trabalhos de campo usuais orientados na prática escolar, tais

To evaluate the frequency of and factors associated with indeterminate interferon-gamma release assay (IGRA) results in people living with HIV/AIDS (PLWHA). We tested 81 PLWHA in the central-west region of Brazil, using the tuberculin skin test and an IGRA. Information on sociodemographic and clinical variables was gathered through the use of questionnaires and from medical records. The association of those variables with indeterminate results was analyzed by calculating the adjusted ORs in a multivariate logistic regression model. Concordance was evaluated by determining the kappa statistic. Among the 81 patients evaluated, the tuberculin skin test results were positive in 18 (22.2%) of the patients, and the IGRA results were positive in 10 (12.3%), with a kappa of 0.62. The IGRA results were indeterminate in 22 (27.1%) of the patients (95% CI: 17.8-38.1%). The odds of obtaining indeterminate results were significantly higher in smokers (adjusted OR = 6.0; 95% CI: 1.4-26.7) and in samples stored for less than 35 days (adjusted OR = 14.0; 95% CI: 3.1-64.2). Patients with advanced immunosuppression (CD4+ T-cell count < 200 cells/mm3) were at a higher risk for indeterminate results (OR adjusted for smoking and inadequate duration of sample storage = 4.7; 95% CI: 0.91-24.0), although the difference was not significant. The high prevalence of indeterminate results can be a major limitation for the routine use of IGRAs in PLWHA. The need to repeat the test increases its costs and should be taken into account in cost-effectiveness studies. The processing of samples can significantly alter the results.

álise pela Teoria da Resposta ao Item foram: avaliação da dimensionalidade, estimação dos parâmetros dos itens e construção da escala. O estudo da dimensionalidade foi realizado sobre a matriz de correlação policórica e análise fatorial confirmatória. Para a estimação dos parâmetros dos itens, foi utilizado o Modelo de Resposta Gradual de Samejima. As análises foram conduzidas no software livre R com o auxílio dos pacotes psych e mirt. A análise permitiu a visualização dos parâmetros dos itens e suas contribuições individuais na mensuração do traço latente, gerando mais informação, permitindo a construção de uma escala com um modelo interpretativo que demonstra a evolução da piora da qualidade de vida em cinco níveis. Quanto aos parâmetros dos itens, houve bom desempenho daqueles referentes ao estado somático, pois apresentaram melhor poder de discriminar os indivíduos com pior qualidade de vida. Os itens relacionados ao estado mental foram os que contribuíram com menor quantidade de informação psicométrica no MINICHAL. Conclui-se que o instrumento é indicado para a identificação da deterioração da qualidade de vida em hipertensão arterial. A análise do MINICHAL pela Teoria da Resposta ao Item permitiu identificar novas facetas desse instrumento ainda não abordadas em estudos anteriores.

Qualidade da Atenção Básica em 2012. Baseado na Teoria de Resposta ao Item, o Modelo de Resposta Gradual de Samejima foi utilizado para estimação do escore relacionado ao nível de coordenação. Os coeficientes alfa de Cronbach, Spearman e ponto bisserial foram utilizados para análise da consistência interna e da correlação entre os itens e de itens com o escore total. Foram avaliadas as suposições de unidimensionalidade e de independência local dos itens. Gráficos do tipo nuvem de palavras auxiliaram na interpretação dos níveis de coordenação. Os itens do Programa com maior discriminação do nível de coordenação foram: existência de telefone/internet, fluxos institucionais de comunicação e ações de apoio matricial. A frequência de contato de especialistas com a atenção básica e prontuário eletrônico integrado exigiram maior nível de coordenação das equipes. O coeficiente alfa de Cronbach total 0,8018. Os itens fluxos institucional de comunicação e telefone/internet tiveram maior correlação com o escore total. Os escores de coordenação variaram entre -2,67 (mínimo) e 2,83 (máximo). Maior grau de comunicação, troca de informações, apoio matricial, cuidado no território e domicílio tiveram peso relevante nos níveis de coordenação. A capacidade de disponibilizar a informação e a frequência de contato entre os profissionais são elementos importantes para o cuidado abrangente, contínuo e de qualidade.

This paper is a reflection about the use of History of Science in the curriculum of formal education, through the discussion concerning cultural elements of several ethnic groups in Brazil, in actions related to astronomy education. The work was developed in the framework of an extension course and the analysis undertaken here refers to a meeting that discussed didactic sequences relating to that theme, based on the Brazilian law 11.645/2008, which states the obligation to present the subject "African-brazilian and indigenous History and Culture" in the official curriculum. The extension action was developed with teachers who teach Natural Sciences, in São Paulo state, discussing issues related to the use of History of Science and the relationship with cosmogonies from Iorubá and Tupi peoples, highlighting how they can enhance the work with Astronomy(ies) in the classroom. It was observed that the participants had not yet presented these themes in their classes and also did not participate in training courses that discussed these subjects.

administrado durante um período de 6 meses no tratamento do hiperparatireoidismo secundário (SHPT) em pacientes submetidos a hemodiálise convencional, com acompanhamento de perto da resposta do tratamento. Realizou-se um ensaio clínico de fase 4 que comparava os dados clínicos com os dados do laboratório antes e depois dos 6 meses de tratamento. Incluíram-se os pacientes SHPT em hemodiálise sem experiência com os metabólitos da vitamina D ou que fracassaram com a terapia em uso. Analisaram-se as características clínicas e de laboratório. As análises de eficácia se basearam nos níveis do hormônio da paratireóide intacto (iPTH) e foram realizadas usando dados dos pacientes que completaram os 6 meses de tratamento. Dezenove dos 26 pacientes registrados completaram os 6 meses de tratamento. Todos os pacientes mostraram níveis de referência iPTH reduzidos (redução média, 371,8 pg/mL; 95% CI, 273,3-470.2 pg/mL]; 17 pacientes (89,5%) tiveram reduções superiores a 30%. Doze pacientes (63%) conseguiram o sucesso terapêutico (definido como níveis de soros iPTH de 150-300 pg/mL), com um tempo médio de 2 meses a partir do início do tratamento. Todos os episódios de hipercalcemia (n = 2) e de hiperfosfatemia (n = 34) reportados foram assintomáticos. Não se informaram AEs graves importantes relacionados à terapia. O paricalcitol foi administrado de forma segura e se associou às reduções significativas nos níveis de iPTH durante o período do estudo.

un marco para la evaluación de herramientas informáticas diseñadas para dar soporte en la en los procesos de definición, gestión e implementación de estos modelos. El marco de evaluación propuesto se basa en una investigación previa para obtener consenso en la definición de requisitos esenciales en esta área. A partir de los 20 requisitos funcionales acordados, un conjunto de 50 criterios de conformidad fueron definidos y aplicados en la evaluación de las herramientas existentes. Un total de 9 de las 11 iniciativas identificadas desarrollando herramientas para el modelado de información clínica fueron evaluadas. Los resultados muestran que las funcionalidades relacionadas con la gestión de tipos de datos, especificaciones, metadatos y mapeo con terminologías u ontologías tienen un buen nivel de adopción. Se identifican posibles mejoras en áreas relacionadas con los procesos de modelado de información. Otros criterios relacionados con presentar las relaciones semánticas entre conceptos y la comunicación con servidores de terminología tienen un bajo nivel de adopción. El marco de evaluación propuesto fue probado y validado satisfactoriamente contra un conjunto representativo de las herramientas existentes. Los resultados identifican la necesidad de mejorar el soporte de herramientas a los procesos de modelado de información y desarrollo de software, especialmente en las áreas relacionadas con gobernanza, participación de profesionales clínicos y la optimización de la validación técnica en los procesos de pruebas técnicas. Esta investigación ha confirmado el potencial de este marco de evaluación para dar soporte a los usuarios en la toma de decisiones sobre que herramienta es más apropiadas para su organización. © The Author 2016.

surgimento de sintomas e/ou sinais limitantes. Neste exame se mensura a ventilação (VE), o consumo de oxigênio (VO2), a produção de gás carbônico (VCO2) e as demais variáveis de um teste de exercício convencional. Adicionalmente, podem ser verificadas, em situações específicas, a oximetria de pulso e as alças fluxo-volume antes, durante e após o esforço. A análise integrada dos dados permite a completa avaliação dos sistemas cardiovascular, respiratório, muscular e metabólico no esforço, sendo considerado padrão-ouro na avaliação funcional cardiorrespiratória.1-6 O TCPE permite definir mecanismos relacionados à baixa capacidade funcional, os quais podem ser causadores de sintomas como a dispneia, correlacionando-os com alterações dos sistemas cardiovascular, pulmonar e musculoesquelético. Também pode ser de grande aplicabilidade na avaliação prognóstica em cardiopatas, pneumopatas e em pré-operatório, além de auxiliar na prescrição mais criteriosa do exercício em sujeitos normais, em atletas, em cardiopatas e em pneumopatas. Assim como ocorre com o uso clínico, a pesquisa nesse campo também cresce e várias contribuições científicas de pesquisadores nacionais são publicadas em periódicos de alto fator de impacto. Sendo assim, o objetivo deste documento é fornecer uma revisão ampla da aplicabilidade do TCPE nas diferentes situações clínicas, bem como servir como guia prático na interpretação desse teste propedêutico.

mortalidade (SIM). A probabilidade de sobrevida global e específica foi estimada pelo tempo decorrido entre a data do primeiro tratamento ambulatorial, entre 2002 e 2003, até o óbito dos pacientes ou fim do estudo. O modelo de regressão de riscos competitivos de Fine e Gray foi ajustado segundo as variáveis: idade ao diagnóstico, região de residência, estadiamento clínico do tumor, tipo de tratamento oncológico ambulatorial e internação na avaliação dos fatores associados ao risco de óbito dos pacientes. Dos 16.280 pacientes estudados, a idade média foi de 70 anos, cerca de 25% foi a óbito devido ao câncer de próstata e 20% por outras causas. A probabilidade de sobrevida global foi de 0,50 (IC95% 0,49-0,52) e a específica 0,70 (IC95% 0,69-0,71) . Os fatores associados ao risco de óbito dos pacientes foram: estádio III (HR = 1,66; IC95% 1,39-1,99) e estágio IV (HR = 3,49; IC95% 2,91-4,18), tratamento quimioterápico (HR = 2,34; IC95% 1,76-3,11) e internação (HR = 1,6; IC95% 1,55-1,79). O diagnóstico tardio do tumor, tratamentos não curativos e pior condição clínica foram fatores relacionados à pior sobrevida e ao maior risco de óbito dos pacientes com câncer próstata no Brasil.

elementares e poderes calorificos. O resultado traduziu-se num conjunto de parâmetros empiricos de interesse pratico que permitiram elucidar o comportamento geral da pirolise de biomassa numa gama ampla de condicoes operatorias. Para alem disso, propos-se um modelo empirico para a composicao dos volateis que pode ser integrado em modelos compreensivos de reatores desde que os parâmetros usados sejam adequados ao combustivel ensaiado. Esta abordagem despoletou um conjunto de ensaios de pirolise com varias biomassas, lenhina e celulose, e temperaturas entre os 600 e 975ºC. Elevadas taxas de aquecimento do combustivel foram alcancadas em reatores laboratoriais de leito fluidizado borbulhante e leito fixo, ao passo que um sistema termo-gravimetrico permitiu estudar o efeito de taxas de aquecimento mais baixas. Os resultados mostram que, em condicoes tipicas de processos de combustao e gasificacao, a quantidade de volateis libertada da biomassa e pouco influenciada pela temperatura do reator mas varia bastante entre combustiveis. Uma analise mais aprofundada deste assunto permitiu mostrar que o rendimento de carbonizado esta intimamente relacionado com o racio O/C do combustivel original, sendo proposto um modelo simples para descrever esta relacao. Embora a quantidade total de volateis libertada seja estabelecida pela composicao da biomassa, a respetiva composicao quimica depende bastante da temperatura do reator. Rendimentos de especies condensaveis (agua e especies orgânicas), CO2 e hidrocarbonetos leves descrevem um maximo relativamente a temperatura para dar lugar a CO e H2 as temperaturas mais altas. Nao obstante, em certas gamas de temperatura, os rendimentos de algumas das principais especies gasosas (e.g. CO, H2, CH4) estao bem correlacionados entre si, o que permitiu desenvolver modelos empiricos que minimizam o efeito das condicoes operatorias e, ao mesmo tempo, realcam o efeito do combustivel na composicao do gas. Em suma, os ensaios de pirolise realizados neste

A escala foi incluída em um estudo seccional aplicado em 1.045 trabalhadoras de enfermagem. Uma subamostra de 222 participantes respondeu ao questionário pela segunda vez, com intervalo de sete a 15 dias. Os dados foram coletados entre outubro de 2012 e maio de 2013. A consistência interna da escala foi avaliada pelo coeficiente de alpha de Cronbach e a confiabilidade teste-reteste, pelo índice kappa ponderado quadrático, pelo kappa ajustado pela prevalência e pelo coeficiente de correlação intraclasse. A confiabilidade ajustada pela prevalência (ka) das dimensões da escala variou de 0,80-0,83 para o excesso de comprometimento, 0,78-0,90 para o esforço e 0,76-0,93 para a recompensa. Na maioria das dimensões, os valores do escore mínimo e máximo, média, desvio-padrão e alpha de Cronbach no teste e no reteste foram semelhantes. Somente na subdimensão estima social (recompensa) houve pequena variação no desvio padrão (2,24 no teste e 3,36 no reteste) e no coeficiente de alpha de Cronbach (0,38 no teste e 0,59 no reteste). A versão brasileira da escala apresentou índices adequados de fidedignidade quanto à estabilidade temporal, o que sugere a adequação da escala para uso em populações com características semelhantes à do estudo.

morfologia pancreática e peripancreática. O entendimento dos diversos subtipos da doença e identificação de suas possíveis complicações requer familiaridade com a terminologia padrão, a qual permite comunicação efetiva entre os diversos membros da equipe multidisciplinar. Demonstrar terminologia e os parâmetros para identificação das diferentes classificações da doença a partir do consenso internacional para as pancreatites agudas (Classificação de Atlanta 2012. Busca e análise de artigos no "Portal de Periódicos da CAPES" com descritores "pancreatite aguda" e "Revisão de Atlanta". : Foram selecionados 23 artigos que continham descrições radiológicas, manejo ou dados estatísticos relacionados à doença. Dados estatísticos adicionais foram obtidos no sistema Datasus e Censo Demográfico 2010. O critério de diagnóstico radiológico adotado foi o do Colégio Americano de Radiologia. A "Classificação da pancreatite aguda - 2012: revisão da classificação de Atlanta e definições por consenso internacional" tenta eliminar a inconsistência e divergências a partir da determinação de uniformidade para os achados radiológicos, em especial à terminologia relacionada às coleções de fluidos. Termos mais abrangentes como "abscesso pancreático" e "flegmão" entraram em desuso e a evolução da coleção de fluidos pode ser descrita como: "coleções peripancreáticas agudas", "coleções necróticas agudas", "pseudocisto" e "necrose pancreática murada ou isolada". A tomografia computadorizada e a ressonância magnética representam as melhores técnicas com cortes sequenciais disponíveis para diagnóstico. A adequação da terminologia é ponto crítico e deve permitir o manejo do paciente por múltiplos profissionais, estratificação de risco e adequação de tratamento.

ão plano de saúde privado. Para avaliar os fatores relacionados a ter pedido médico de mamografia, foram calculadas odds ratios brutas e ajustadas e os respectivos IC95% por regressão logística. Foram também analisados os principais motivos informados para não ter realizado mamografia após ter o pedido médico, assim como o tempo entre ter realizado o exame e o recebimento do resultado. Das mulheres entrevistadas, 66,7% tiveram um pedido médico para mamografia (59,4% entre as que eram usuárias do SUS e 83,9% entre as portadoras de plano de saúde privado). Ter plano de saúde privado, maior nível de escolaridade e ser de cor branca se associaram positivamente a ter o pedido médico. Apenas 5,4% (IC95% 4,8-6,0) das mulheres que receberam solicitação médica não conseguiram fazer mamografia - 7,6% eram dependentes do SUS enquanto 1,7% eram portadoras de plano de saúde. Os motivos mais reportados de não conseguir realizar o exame foram: não achar necessário; ter o exame marcado, mas ainda não realizado; e não ter conseguido marcar. Mais de 70% das mulheres receberam o resultado antes de completar um mês da realização. As barreiras de acesso a ter pedido médico para rastreamento mamográfico para o câncer de mama são maiores entre mulheres que dependem exclusivamente do SUS.

Argot Ambiente-Estrategia Resumen La estrategia ambiental – como es promocionada por la Convención Biológica sobre Diversidad en 2000 – es una estrategia para un manejo holístico, sustentable y equitativo de recursos naturales, que habrá de implementarse por vía de los 12 Principios de Malawi. Estos principios describen la necesidad de manejar la naturaleza en términos de ecosistemas dinámicos, mientras se compromete totalmente con las personas locales. Es un concepto ambicioso. Hoy en día, el término es común en la investigación y la literatura de políticas sobre el manejo ambiente. Sin embargo, se han relacionado múltiples significados con el término, lo que resulta en confusión. Revisamos referencias a la estrategia ambiental de 1957 a 2012 e identificamos tres usos principales: como una alternativa para manejo ambiental o basado en ecosistemas; en referencia a una estrategia integrada y equitativa para el manejo de recursos según la CBD; y como un término que indica un enfoque en el entendimiento y la valuación de los servicios ambientales. Aunque los usos de este término y sus variantes pueden traslaparse en su significado, típicamente no reflejan en su totalidad los valores de la estrategia ambiental como fue definida por la CBD. Por ejemplo, actualmente hay un énfasis creciente en los servicios ambientales, pero enfocarse solamente en estos no promueve la descentralización del manejo o el uso de todas las formas de conocimiento, siendo ambas integrales para el concepto de la CBD. Resaltamos que los Principios de Malawi están en riesgo de ser olvidados. Para entender mejor estos principios, se requiere de más esfuerzo para implementarlos. Dichos esfuerzos deben ser evaluados, idóneamente con estrategias comparativas, antes de permitir que el concepto de la CBD de manejo holístico y comprometido socialmente sea abandonado o reemplazado. Es posible que los intentos por implementar los 12 principios juntos enfrentarán muchos obst

potenciales de los pagos por servicios ambientales (PSA) y áreas protegidas (APs) sobre los resultados ambientales y las subsistencias locales en los países en desarrollo son polémicos y se han debatido ampliamente. La evidencia disponible es escasa; ha habido pocas evaluaciones rigurosas de los impactos ambientales y sociales de las APs y particularmente los PSA. Medimos el impacto sobre los bosques y el bienestar humano en tres diferentes programas de PSA que se llevan a cabo dentro de dos APs en el norte de Camboya usando un panel de aldeas de intervención y controles emparejados. Tanto los PSA como las APs brindaron resultados ambientales adicionales en relación a los contrafácticos, esto quiere decir que redujeron las tasas de deforestación significativamente en relación a los controles. Las áreas protegidas incrementaron el acceso seguro a los recursos del suelo y el bosque para las viviendas locales, beneficiando a los usuarios de los recursos del bosque pero restringiendo la habilidad de las viviendas para expandirse y diversificar su agricultura. Los impactos de los pagos por servicios ambientales sobre el bienestar de las viviendas estuvieron relacionados con la magnitud de los pagos proporcionados. Los dos programas de PSA de mayor paga y con conexión al mercado tuvieron impactos positivos significativos, mientras que un programa de menor paga con el objetivo de proteger a la biodiversidad no tuvo un efecto detectable sobre las viviendas, a pesar de sus resultados ambientales positivos. Las viviendas que se inscribieron a los programas de PSA con mayor paga, sin embargo, necesitaban típicamente más bienes capitales, por lo que eran menos pobres y tenían mayor seguridad alimentaria que otros aldeanos. Por esto, mientras los impactos de las APs sobre el bienestar de las viviendas fueron limitados en general y variaron dependiendo de las estrategias de subsistencia, los programas de PSA tuvieron impactos positivos significativos sobre las viviendas para

coorte de 277 pacientes matriculados no Instituto Nacional do Câncer em 2011. Os custos foram estimados sob a perspectiva do hospital como prestador de serviços de referência para o SUS. Insumos e procedimentos utilizados foram identificados e quantificados, por paciente, sendo a eles atribuídos valores monetários, consolidados por fases da assistência definidas. As análises tiveram caráter descritivo com custos em reais (R$). Em termos globais, a coorte representou um custo de R$2.473.559,91, sendo 71,5% relacionados à atenção ambulatorial e 28,5% as internações. Na atenção ambulatorial, predominaram os custos com radioterapia (34%) e quimioterapia (22%). Os resultados apontaram para custos menores na fase inicial de tratamento (7,2%) e custos muito elevados na fase de manutenção (61,6%). Por fim, identificaram-se diferenças estatisticamente significativas das médias dos custos por faixas etárias, níveis de escolaridade, desempenho físico e tipo histológico. Este estudo fornece um retrato atual, útil e relevante sobre os custos de pacientes com câncer de pulmão não pequenas células assistidos em um hospital público de referência e provê elementos sobre a magnitude do problema do câncer no âmbito da saúde pública. Os resultados ratificam a importância do tratamento radioterápico e das internações como principais componentes de custo do tratamento. Apesar de algumas perdas de seguimento avalia-se que, para cerca de 80% dos pacientes incluídos no estudo, as estimativas aqui apresentadas sejam satisfatoriamente fidedignas ao cuidado da doença, sob a perspectiva de um prestador de referência do SUS, fornecendo elementos para a gestão do serviço, bem como para estudos que redundem em formas mais racionais de alocação de recursos.

úde relacionados à ocorrência de sífilis em mulheres atendidas em maternidades públicas. Trata-se de um estudo caso-controle (239 casos e 322 controles) com mulheres admitidas em sete maternidades do município do Recife, no período de julho de 2013 a julho de 2014. As mulheres elegíveis foram recrutadas após o resultado do VDRL (Venereal Disease Research Laboratory) sob qualquer titulação. A seleção dos casos e controles considerou o resultado da sorologia por ELISA (enzyme-linked immunosorbent assay), variável dependente utilizada como diagnóstico para sífilis neste estudo. As variáveis independentes foram agrupadas em: sociodemográficas; comportamentais; e antecedentes clínicos e obstétricos; e assistência à saúde no pré-natal e na maternidade. As informações foram obtidas por meio de entrevista, durante o internamento, por aplicação de um questionário. Foi calculado odds ratio (OR), intervalo de confiança de 95% e realizada análise de regressão logística para identificar os fatores preditores da variável a ser explicada. A análise de regressão logística identificou como fatores determinantes para a sífilis gestacional: nível de escolaridade fundamental incompleto ou analfabeta (OR = 2,02), ausência de acesso a telefone (OR = 2,4), religião católica (OR = 1,70), quatro ou mais gestações (OR = 2,2), três ou mais parceiros sexuais no último ano (OR = 3,1), uso de drogas ilícitas antes dos 18 anos (OR = 3,0) e uso de drogas ilícitas por parte do atual companheiro (OR = 1,7). Além desses, foram observadas a ocorrência de apenas uma a três consultas ao pré-natal (OR = 3,5) e história anterior de infecção sexualmente transmissível (OR = 9,7). Fatores sociodemográficos, comportamentais e de assistência à saúde estão associados à ocorrência de sífilis em mulheres e devem ser levados em consideração na elaboração de estratégias universais direcionadas à prevenção e controle da sífilis, porém com foco em situa

The sequences have been deposited in NCBI database under the accession numbers (EF058280) for GWSS-V1, WHSg013C11 and (EF058281) for GWSS-V2, WHSg024H02. (author) [Spanish] Dos fragmentos de 610 y 839 pares de bases fueron aislados apartir de una genoteca de expresion derivada de las glandulas salivales del cucarron de las alas cristalinas (GWSS), Homalodisca vitripennis, Germar 1821 (syn. H. coagulata) el cual es vector de la enfermedad de Pierce de las uvas. Los resultados de alineamiento utilizando BLASTX, BLASTP y el analisis filogenetico utilizando PAUP indicaron que los fragmentos de DNA estaban relacionado de manera mas cercana a viruses en la familia Reoviridae, genero Phytoreovirus, y especificamente a los virus del enanismo del arroz (RDV) y al virus del tumor de las grietas (WTV). El cucarron de las alas cristalinas es un saltahoja que se alimenta no solo del xilema sino tambien del floema y del mesofilo. Saltahojas del genero Agallian, son los principales vectores de WTV, el cual infecta el floema de plantas dicotiledoneas tumoraciones en las hojas y en las raices. WTV es transmitido por saltahojas y es el unico reovirus que es capaz de infectar tanto tejidos del xilema como del floema. El comportamiento alimentario del GWSS y su amplio rango de hospederos que incluye pastos y plantas herbaceas y lenosas podria proveer la interaccion entre estos dos organismos facilitando la adquisicion y tranmision de fitoreovirus por el GWSS. Un adecuado monitoreo de el incremento en la expansion de reoviruses en cultivos de gramineas asociados al los vinedos en donde GWSS ocurre en regiones tales como el sur de California, y en general el sur de los Estados Unidos, podria proveer un mejor entendimiento del papel del GWSS como vector de fitoreovirus y otros patogenos de

To describe the prevalence of work-related musculoskeletal disorder (WMSD) and analyze the factors associated with this outcome in the Brazilian population. In this cross-sectional, population-based study, we use data from the National Survey on Health (PNS) of 2013. The sample was composed of 60,202 Brazilians aged 18 years or older. The outcome variable was the occurrence of self-reported WMSD. Sociodemographic and occupational characteristics, personal resources, and health conditions were investigated as explanatory variables. Analyses were performed with the software Stata 12.0 and considered the weighting imposed by the sampling design of the study. Then, univariate and multivariate binary logistic models were carried out, considering a significance level of 5%. The results obtained indicated that the prevalence of WMSD in the Brazilian population was of 2.5%, ranging from 0.2% (Acre) to 4.2% (Santa Catarina). The factors associated with a greater chance of occurrence of WMSD were: female sex (OR = 2.33; 95%CI 1.72-3.15); be temporarily away from work (OR = 2.44; 95%CI 1.41-4.23); be exposed to noise at the workplace (OR = 2.16; 95%CI 1.68-2.77); seniority equal to or greater than 4.5 years at the current job (OR = 1.37; 95%CI 1.09-1.72); participate in volunteer work (OR = 1.65; 95%CI 1.25-2.17); report medical diagnosis of arthritis or rheumatism (OR = 2.40; 95%CI 1.68-3.44); and depression (OR = 2.48; 95%CI 1.86-3.31). On the other hand, factors associated with less chance of WMSD were: not having a partner (OR = 0.73; 95%CI 0.37-0.71) and working in an open environment (OR = 0.51; 95%CI 0.37-0.71). The associated factors and the prevalence found indicate regional and gender differences. Special attention to comorbidities and environmental noise monitoring would benefit the health of workers in the Country.

. Estudo prospectivo com dois grupos de pacientes. Em ambos os grupos verificou-se a prevalência do H. pylori no pré-operatório através de histopatologia, mas em apenas um dos grupos, nos casos de H. pylori positivo realizou-se o tratamento com antibioticoterapia e inibidor de bomba de próton com realização de nova endoscopia no 6° e 12° mês pós-operatório. Avaliou-se 216 pacientes, com as seguintes características: sexo feminino (68,1%), faixa etária entre 30-40 anos, com 31,9% e 31%, respectivamente. De acordo com o IMC, 17,6% apresentavam obesidade moderada, 82,4% obesidade severa/mórbida e 9,7% superobesidade. Nos pacientes submetidos à endoscopia, a positividade do H. pylori se manifestou em 40,7%, sendo responsável pela atividade inflamatória na mucosa gástrica (p<0,001). No pós-operatório, investigou-se a mucosa gástrica através de endoscopia e histopatologia no 6° e 12° mês, que demonstrou normalidade no neorreservatorio gástrico em 84% dos pacientes, e a incidência de H. pylori foi 11% aos seis meses e 16% aos 12 meses, sendo a presença de processo inflamatório relacionado com a infecção pela bactéria (p<0,001). - H. pylori apresenta prevalência similar tanto em obesos que irão submeter-se à cirurgia bariátrica quanto à população em geral; há baixa incidência dele no 6° e 12° mês após a operação e isto deve-se provavelmente à sua erradicação quando detectado no pré-operatório; quando presente a doença inflamatória no neorreservatório gástrico possui relação direta com a infecção por H. pylori.

, its involvement with the evaluations at the federal level can also be stimulated. Analisar alcances e limites do uso de metodologia participativa de avaliação junto a gestores e gerentes municipais de saúde. Pesquisa qualitativa com gestores e gerentes de saúde da Comissão Intergestores Regional de uma região de saúde do estado de São Paulo. Representantes de sete municípios membros participaram de sete oficinas facilitadas pelos pesquisadores, com o objetivo de avaliar um problema específico da linha de cuidados sob a perspectiva da integralidade. A análise do material empírico coletado baseou-se na metodologia hermenêutica-dialética e visou a avaliação da metodologia participativa aplicada, segundo sua capacidade de promover um processo de avaliação passível de ser utilizado como suporte à gestão municipal. Com a abordagem participativa de avaliação, foi possível promover debates em profundidade com o grupo, principalmente relacionados à construção da integralidade da atenção e à inclusão da perspectiva do usuário na tomada de decisão, de forma vinculada à busca de solução para problemas concretos dos gestores. Mediante a exploração conjunta, foi aberta a possibilidade de utilização de dados advindos dos sistemas eletrônicos de informação, bem como de informações advindas diretamente dos usuários dos serviços, para enriquecer debates e negociações entre parceiros. Os participantes se mostraram descrentes do potencial de replicação deste tipo de avaliação sem o acompanhamento direto da academia, dada a dificuldade de organização do processo no cotidiano, já tomado por questões emergenciais e políticas. Avaliações de programas e serviços realizadas no âmbito da Comissão Intergestores Regional, partindo do interesse local e facilitando o envolvimento de seus membros pelo uso de metodologias participativas, podem contribuir para a construção da integralidade do cuidado.

regresión logística multivariada para evaluar si la relación entre el TEPT y el sexo pudiera ser explicada por medio de otros factores de riesgo, así como para calcular las tasas y la oportunidad relativa (razón de productos cruzados) de trastornos psiquiátricos a lo largo de la vida. El primer análisis arrojó que la prevalencia de TEPT a lo largo de la vida fue de 4.4% (2.5% para hombres y 6.2% para mujeres). De los hechos traumáticos reportados, la violación sexual tuvo una correlación más alta con el TEPT que los demás hechos traumáticos. Las mujeres tuvieron más probabilidades de experimentar TEPT que los hombres, después de controlar la variable asalto violento. El segundo análisis evidenció que los que habían sufrido traumas a lo largo de la vida tuvieron mayor probabilidad de tener un trastorno psiquiátrico en comparación con aquellos que no reportaron traumas. También se encontró que los que sufrieron su primer trauma durante la infancia tuvieron más probabilidad de desarrollar trastornos de pánico a lo largo de la vida que aquellos que sufrieron su primer trauma en la edad adulta, independientemente del número de traumas que sufrieron y de las diferencias demográficas. Aunque Chile tiene un contexto histórico-cultural y una economía diferente a otros países en los que se ha estudiado anteriormente la epidemiología del TEPT, el presente estudio reflejó tendencias similares a las reportadas en estudios previos. Los hallazgos expuestos enfatizan la importancia de investigar la prevalencia del TEPT, los patrones de comorbilidad del TEPT y las diferencias de sexo en la prevalencia del TEPT en diferentes países. También estos resultados sugieren que los sucesos traumáticos en la infancia (y no en la adultez) pueden estar relacionados con la ocurrencia de trastornos psiquiátricos específicos. PMID:21113425

Im in vitro Lymphozyten-Stimulationstest waren alle Tiere und Klassen responder. Tiere mit A10 BoLA I zeigten höhere c.p.m. und Indexwerte als die anderen; diese Werte waren in signifikant positiver Beziehung mit der PPD von M. bovis und auch mit M. avium (P < .01). BoLA Typ A14 zeigte leicht signifikant positive Korrelation mit wirksamerer Phagozyten Aktivität. BoLA Klasse I Typ scheint nicht den Prozentsatz der positiven Zellen der Klasse II und der Leukozyten der PBM signifikant zu beeinflussen. RESUMEN: Polimorfismo de BoLA clase I y immunidad a los antigenos del M. bovis Se escojeron 47 novillos dentro de un grupo de 119 animales que segun analisis previamente hecha tenian BoLA de clase I. Estos 47 novillos fueron escojidos de manera que tuvieran 9 distintos tipos de MHC (A6, A6.9, A10, A11, A14, A15, A30, W16, M103), la misma edad, las mismas condiciones de cria. Estos animales fueron inoculados subcutaneo con M. bovis matados en una suspension oleosa y la misma inoculacion fue repetida una secunda vez despues de dos dias. Por cada animal se tomaron muestras de sangre antes y 21 dias despues de la inoculacion de arriba. Las muestras de sangre fueron pruebaoas con: 1. Stimulacion Lymhocitaria con PPD bovina y avicola. 2. Actividad phagocitaria a M. bovis. 3. Expresion sobre la superficie celular de moleculas de clase II. 4. Porcentaje de poblaciones y de subpob-laciones de leucocitos. Todos los animales y todos los tipos de MHC dieron respuestas positivas en las pruebas de Stimulacion Lymphocitaria. Los animales que tenian la BoLA A10 presentaron valores de c.p.m. y indices mas altos de los demas animales. Estos valores se encontraron significativamente y positivamente relacionados sea a la PPD bovina que a la PPD avicola. Por medio de la analisis de varianzas se encontro que el

are suggestive but not specific to the infection. The other forms were not conclusive of the presence of HP. Estudos com tecnologias mais recentes como endoscopia com magnificação e cromoscopia mostraram que vários aspectos endoscópicos estão claramente associados à infecção por Helicobacter pylori. A descrição de padrões diferenciados de enantema no corpo gástrico através da magnificação de imagens reavivou o interesse na identificação desses padrões pela endoscopia convencional. Validar os padrões morfológicos de mucosa gástrica usando videogastroendoscopia convencional relacionados à gastrite por infecção por Helicobacter pylori, permitindo previsibilidade do seu diagnóstico e o direcionamento de biópsias. Estudo prospectivo de 339 pacientes consecutivos com análise das imagens de videogastroendoscopia obtidas, gravadas e armazenadas em banco de dados. Estas imagens foram estudadas com relação à presença ou não do Helicobacter pylori diagnosticado por teste rápido de urease e/ou por pesquisa direta por estudo anatomopatológico. Foram estudados: a) aspecto normal da mucosa; b) nodularidade da mucosa; c) enantema inespecífico difuso de antro e corpo; d) enantema em mosaico ou salpicado; e) enantema em estrias ou faixas; f) erosões elevadas; g) erosões planas; h) pólipos de glândulas fúndicas. Os principais critérios de exclusão foram o uso de medicamentos, tratamento prévio de HP e outras entidades que pudessem interferir nos resultados. Aplicando os critérios de exclusão, incluíram-se 170 dos 339 pacientes sendo 52 (30,58%) positivos para Helicobacter pylori e 118 negativos. No grupo positivo os achados que mais se associaram com a infecção foram: nodularidade no antro (26,92%); presença de erosões elevadas (15,38%) e mucosa em mosaico no corpo (21,15%). No grupo negativo o aspecto normal da mucosa foi de 66,94%; enantema em estrias ou faixas em 9,32%; erosões planas em 11,86%; e pólipos de glândulas fúndicas 11

A family history of hypertension is associated with vascular and autonomic abnormalities, as well as an impaired neurohemodynamic response to exercise. To test the hypothesis that normotensive individuals with a family history of hypertension present an impaired peripheral vascular resistance response to exercise. The study included 37 normotensive volunteers of both sexes who were sedentary, eutrophic, and nonsmokers, comprising 23 with (FH+; 24 ± 3 years) and 14 without (FH-; 27 ± 5 years) a family history of hypertension. Blood pressure, heart rate (DIXTAL®), forearm blood flow (Hokanson®), and peripheral vascular resistance were simultaneously measured for 3 minutes during rest and, subsequently, for 3 minutes during an isometric exercise at 30% of maximal voluntary contraction (Jamar®). At rest, the FH+ and FH- groups present similar mean blood pressure (83 ± 7 versus 83 ± 5 mmHg, p = 0.96), heart rate (69 ± 8 bpm versus 66 ± 7 bpm, p = 0.18), forearm blood flow (3 ± 1 mL/min/100 mL versus 2.7 ± 1 mL/min/100 mL, p = 0.16), and peripheral vascular resistance (30 ± 9 units versus 34±9 units, p = 0.21), respectively. Both groups showed a significant and similar increase in mean blood pressure (∆ = 15 ± 7 mmHg versus 14 ± 7 mmHg, p = 0.86), heart rate (∆ = 12 ± 8 bpm versus 13 ± 7 bpm, p = 0.86), and forearm blood flow (∆ = 0.8 ± 1.2 mL/min/100 mL versus 1.4 ± 1.1 mL/min/100 mL, p = 0.25), respectively, during exercise. However, individuals in the FH+ group showed no reduction in peripheral vascular resistance during exercise, which was observed in the FH- group (∆ = -0.4 ± 8.6 units versus -7.2 ± 6.3 units, p = 0.03). Normotensive individuals with a family history of hypertension present an impaired peripheral vascular resistance response to exercise.

In this report will be presented the development of educational resources for the presentation of concepts of astronomy in the early grades of elementary school. This material is composed by presentations developed with the use of new technological resources, by the development of experiments and by the presentation of curiosities related to this field. The experiments were constructed with low cost material in order to allow the students involved to rework them in other occasions. The material presented aims to emphasize the relationship between Astronomy and the daily life of students. The inclusion of Astronomy in elementary school is a way to demonstrate to students how this area is present in an active way in their daily lives. The classes involved in the project participated in a survey with the aim of providing information about the prior knowledge they had about topics in astronomy that were considered during the project. With the experiments conducted, and the aid of new technologies, the astronomical concepts were presented to students of 4th and 5th years of basic education of a municipal school of Campos dos Goytacazes (RJ). After the presentations new data collections were carried out with the aim of verifying the level of learning obtained and it was observed that the method used was an important tool to aid the process of teaching and learning. The project obtained good results. En este informe se presenta el desarrollo de recursos pedagógicos para la presentación de los conceptos de la astronomía en los primeros grados de la escuela primaria.

combined oral contraceptives were the most frequently reported (71.6%) and low-level levonorgestrel + ethinylestradiol combination accounted for 38.7% of them. The most frequently reported medicines are included in the Relação Nacional de Medicamentos Essenciais (RENAME - National List of Essential Medicines. Most women aged 15 to 49 who reported using contraceptives had access to the medicine and use monophasic combined oral contraceptives of appropriate efficiency and safety purchased by direct payment, mainly from retail pharmacies. Analisar a prevalência do uso atual de contraceptivos orais e injetáveis por mulheres brasileiras, segundo variáveis demográficas, socioeconômicas e aspectos relacionados ao acesso a esses medicamentos. Estudo transversal, analítico, baseado nos dados da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), de base populacional e amostra probabilística, realizada entre setembro/2013 e fevereiro/2014, em 20.404 domicílios urbanos brasileiros. A prevalência foi calculada a partir do relato das mulheres de 15 a 49 anos, não grávidas, sobre o uso de contraceptivos orais ou contraceptivos injetáveis. As variáveis independentes foram sexo, idade, escolaridade, nível socioeconômico, região geográfica e situação conjugal. Também foram analisados acesso, fontes de financiamento, fontes de obtenção e medicamentos citados. As análises estatísticas consideraram intervalos de confiança de 95% (IC95%) e teste Qui-quadrado de Pearson para avaliação da significância estatística das diferenças entre os grupos, considerando o nível de significância de 5%. A prevalência de uso de contraceptivos orais (CO) foi 28,2% e de contraceptivos injetáveis (CI), 4,5%. A prevalência de contraceptivos orais foi maior no Sul (37,5%) e menor no Norte (15,7%). Para contraceptivos injetáveis não houve diferença entre as regiões. O acesso foi maior para as usuárias de contraceptivos orais (90

biotopes souterrains à des études multidisciplinaires qui intègrent l'écologie et l'hydrogéologie. L'approche multidisciplinaire cherche à élucider le fonctionnement des écosystèmes souterrains et leur rôle consistant à maintenir la qualité des eaux souterraines et de surface. Dans les écotones des eaux de la surfaces des aquifères, les gradients géochimiques et les biofilms microbiologiques contrôlent les transformations de la qualité de l'eau. La faune de subsurface (stygofauna) construisent les biofilms, altèrent la taille des pores interstitiels à travers leur mouvement, et transportent physiquement des matériaux à travers l'environnement des eaux souterraines. Par ailleurs, les changements de leur population signalent un déclin de la qualité de l'eau. Une meilleure intégration de l'écologie des eaux souterraines, de la biogeochimie, et de l'hydrogéologie pourra faire avancer de manière efficace de notre compréhension des écosystèmes souterrains, et spécialement en terme de bioremédiation des eaux souterraines contaminées, de maintenance et d'amélioration de la qualité des eaux de surface dépendant des écosystèmes souterrains, et l'amélioration de la protection des habitats des eaux souterraines durant l'extraction des ressources naturelles. En général, cela conduira à une meilleure compréhension de l'implication de l'hydrogéologie et de la géologie des aquifères à la distribution de la faune de subsurface et aux microbiota, aux processus écologiques tels que les cycles du carbone, et la gestion durable des eaux souterraines. Los entornos ecológicos en ambientes subsuperficiales están relacionados directamente con el flujo de agua subterránea, la conductividad hidráulica, biogeoquímica intersticial, tamaño de los poros, y vínculos hidrológicos con acuíferos adyacentes y ecosistemas superficiales.

Además, incluso si el Río Colorado recargase este Campo Central, el agua subterránea se salinizaría progresivamente. Las restricciones del Acta sobre el uso del agua del CAP afectan los cuatro mecanismos legales del Código de Aguas Subterráneas de Arizona de 1980 relacionados con el Área de Gestión Activa de Tucson: (a) aumento del suministro; (b) requisitos y permisos para la extracción de aguas subterráneas (c) necesidades del Plan de Gestión, particularmente la conservación obligatoria y temas de calidad de aguas; y (d) la obligación de que todas las nuevas subdivisiones usen agua con suministro renovable en lugar de subterránea. Como problemas adicionales se incluye la perturbación de las actividades políticas normales como consecuencia de las demandas para aprobar y poner en marcha el Acta.

associated with BP control assessed by ABPM (p = 0.009 and p = 0.001, respectively). Resistant hypertension was also significantly associated with group G0 (patients with no control or adherence, p = 0.012). There was a decrease in BP control and adherence measured by the MMAS after participation of at least 6 months in the ReHOT clinical trial. A falta de adesão ao tratamento medicamentoso da hipertensão arterial sistêmica (HAS) é uma das principais causas das baixas taxas de controle da doença. Verificar a adesão e fatores relacionados a ela, além do controle pressórico de pacientes que participaram do ensaio clínico Resistant Hypertension Optimal Treatment (ReHOT). Estudo transversal que incluiu todos os 109 pacientes que concluíram o ReHOT há pelo menos 6 meses. Foram excluídos aqueles que não responderam ao novo recrutamento após três tentativas de contato telefônico. Foi realizada avaliação do controle pressórico através de monitorização ambulatorial da pressão arterial (MAPA; PA controlada: pressão arterial [PA] sistólica e diastólica de 24 horas < 130 x 80 mmHg) e avaliação da adesão através de respostas ao questionário Morisky Medication Adherence Scale (MMAS) validado por Bloch, Melo e Nogueira (2008). A análise estatística foi realizada com o programa IBM SPSS statistics 21.0. Para verificar a normalidade da distribuição dos dados, utilizamos testes de curtose e assimetria. As variáveis relacionadas ao objeto de estudo são apresentadas por meio de estatística descritiva. Comparações entre a adesão ao tratamento e demais variáveis foi realizada com o teste t de Student para variáveis independentes e teste do qui-quadrado de Pearson ou exato de Fisher. Para a análise entre pacientes considerando a adesão ao tratamento e controle da PA, foram criados quatro grupos: G0, G1, G2 e G3. Em todos os testes estatísticos consideramos um nível de significância de 5%. Durante o ReHOT, 80% dos pacientes apresentaram controle press

partie sud du bassin de la rivière Augustus, exemple de bassin en roches altérées. Les données concernant le site ont mis en évidence la présence simultanée d'aquifères poreux dans le profil d'altération et d'aquifères de roches fracturées dans le socle. Des campagnes de géophysique aéroportée et d'autres données de forages ont identifié de très nombreux dykes de dolérite traversant le site. Des veines de quartz fracturées ont été trouvées aux marges de ces dykes de dolérite. Des mesures détaillées de niveau des nappes et des estimations des effets barométriques indiquent que ces dykes de dolérite et les veines de quartz fracturées affectent les directions d'écoulement souterrain, favorisant une forte connexion hydraulique entre tous ces aquifères, et influençant également les mécanismes de recharge. La signification hydrogéologique des dykes de dolérite et des veines de quartz fracturées a été analysée en combinant des mesures à haute fréquence du niveau des nappes (toutes les 30 min), de la pluie (toutes les 5 min) et des variations de la pression barométrique (toutes les 30 min). Un modèle conceptuel a été établi pour décrire les différents phénomènes hydrogéologiques de la région étudiée. Ce modèle indique que les veines de quartz aux marges des dykes de dolérite sont une importante composante de l'hydrogéologie des bassins en roches altérées. Entender la hidrogeología de cuencas con rocas meteorizadas es esencial para gestionar diversos problemas relacionados con el incremento de salinidad en muchas ciudades de Australia Occidental. Este artículo presenta los resultados obtenidos en la caracterización de varios emplazamientos con el fin de mejorar el conocimiento general de la hidrogeología en la zona sur de la cuenca del Río Augustus, que sirve como ejemplo de cuenca en rocas meteorizadas.

Metabolic Risk Score defined by the surgical societies. Roux-en-Y gastric bypass (RYGB), because of its well known safety and efficacy and longer follow-up studies, is the main surgical technique indicated for patients eligible for surgery through the Metabolic Risk Score. The vertical sleeve gastrectomy may be considered if there is an absolute contraindication for the RYGB. T2DM patients should be evaluated by the multiprofessional team that will assess surgical eligibility, preoperative work up, follow up and long term monitoring for micro and macrovascular complications. Mesmo considerando o avanço do tratamento clínico ocorrido nos últimos 20 anos, com novos e mais eficientes medicamentos, os dados ainda são desanimadores quanto ao controle da obesidade e da diabete melito tipo 2 (DMT2),com grande parcela de doentes em tratamento clínico ficando fora da meta desejada de controle. Apresentar proposta de Escore de Risco Metabólico para melhor orientar a indicação cirúrgica do diabete em pacientes com índice de massa corpórea (IMC) mais baixo nos quais o uso de procedimento cirúrgico para obesidade ainda é controverso. Foi realizada pesquisa nas bases de dados Pubmed, Medline, Pubmed Central, Scielo e Lilacs entre 2003-2015 correlacionando os descritores:cirurgia metabólica, obesidade e diabete melito tipo 2. Adicionalmente, representantes das sociedades envolvidas emitiram opiniões em pontos nos quais não existia na literatura trabalhos com graus de evidência elevados. Foram encontrados 45 artigos relacionados que foram analisados pelos critérios da medicina baseada em evidências. As opiniões agrupadas procuraram responder as seguintes questões: Porque cirurgia metabólica e não bariátrica?; Mecanismos envolvidos no controle glicêmico; IMC como critério isolado de indicação cirúrgica para o DMT2 não controlado; Resultados de estudos de cirurgia metabólica em IMC<35 kg/m2; Segurança da cirurgia metabólica em pacientes com IMC<35 kg/m2

(CCK), un péptido que se encuentra en el sistema digestivo y el cerebro, esta rela-cionado con el control del apetito en varias especies, incluido el cerdo. Las razas chinas como la Meishan se distinguen por su crecimiento lento y deposición de tejido adiposo. En este estudio hemos descrito las concentraciones de sustancias immunoló-gicamente similares a la colecistoquinina (CCK-IR) en tres regiones del cerebro de lechones Duroc y Meishan utilizando radioimmunoensayo. Los cerebros de cerdos de 1, 10 y 20 días de edad de cada raza fueron examinados. La CCK-IR aumentó con la edad en las tres áreas examinadas (córtex, médula e hipotálamo). Las concentraciones en el córtex aumentaron significativamente de 1 a 10 y de 10 a 20 dias de edad. Las concentraciones en el hipotálamo y médula aumentaron significativamente entre los días 1 y 20. No hubo diferencias significativas en CCK-IR entre las razas en ninguna de las edades estudiadas. Nuestros resultados indican que un aumento en CCK-IR en las regiones del cerebro que participan en el control del consumo de alimente podrían ir paralelas a la habilidad de los lechones para asimilar nutrientes de una dieta sólida. 1993 Blackwell Verlag GmbH.

cicatrisation cutanée. Resumen Introducción Las células madre de adultos se han estudiado extensivamente en estrategias de bioingeniería para la reparación de tejidos. Hemos evaluado el valor clínico y la seguridad de la aplicación de células madre mesenquimales (MSCs) alogenéicas derivadas de la medula ósea para tratar las heridas de la piel en un modelo canino. Hipótesis El transplante tópico alogenéico de MSCs puede acelerar la cicatrización de heridas cutáneas experimentales de todo el grosor de la piel y disminuir la inflamación local. Animales Se estudiaron perros de raza Beagle sanos adultos (n=10; de 3-6 años de edad; 7,2-13,1 kg de peso). Métodos Se crearon heridas de todo el grosor de la piel en el dorso de perros Beagle sanos, y se inyectaron MSCs alogenéicas intradérmicamente. El ritmo de reparación de la herida y el grado de producción de colágeno se analizaron histológicamente utilizando tinciones de hematoxilina-eosina y tricrómico. El grado de proliferación celular y la angiogenesis se evaluaron mediante inmunohistoquímica utilizando anticuerpos específicos para el antígeno de proliferación celular nuclear (PCNA), vimentina y α-actina de músculo liso. La expresión local de mRNA para interleuquina-2 (IL-2), interferón- γ (IFN- γ), factor básico de crecimiento de fibroblastos (BFGF) y metaloproteinasa de matriz-2 se evaluaron mediante RT-PCR. Resultados comparado con las heridas tratadas solo con el vehículo, las heridas tratadas con MSCs mostraron una reparación más rápida y un aumento en la producción de colágeno, proliferación celular y angiogenesis. Además, las heridas tratadas con MSCs mostraron una expresión aumentada de citoquinas proinflamatorias (IL-2 e IFN- γ) y factores relacionados con la reparación de la herida (BFGF y metaloproteinasa de matriz-2). Conclusión e importancia clínica El transplante tópico de MSCs resulta en efectos paracrinos en la proliferación celular y angiogenesis, así como en la

450 ms, une plus grande négativité (N360) fut observée pour les pseudo-caractères comparativement aux caractères des régions du scalp au-dessus des régions médianes fronto-centrales. L'analyse dipôle a localisé le générateur de N360 dans le cortex para-hippocampique droit. Ainsi, le N360 pourrait être une composante N400 et refléter une activation sémantique de haut niveau sur la base des traitements orthographique, phonologique et perceptuel-sémantique. La mayoría de los caracteres chinos están compuestos por un radical semántico a la izquierda y un radical fonético a la derecha. El radical semántico puede proporcionar información semántica y el radical fonético puede proporcionar información relacionada con la pronunciación del carácter entero. Los pseudo-caracteres consistieron en diferentes partes sub-léxicas de los caracteres reales chinos y como consecuencia, también tenían radicales semánticos y fonéticos. Pero éstos no se podían leer y tampoco tenían un significado real. Para investigar los patrones de la activación cortical espaciotemporal subyacentes de los procesamientos ortográfico, fonológico y semántico de los caracteres chinos, utilizamos potencial relacionado con eventos (ERPs) para explorar el procesamiento de caracteres chinos y pseudo-caracteres mientras que 14 sanos estudiantes chinos veían los caracteres de forma pasiva. Los resultados demostraron que ambos, caracteres y pseudo-caracteres chinos evocaban potenciales negativos con picos alrededor de los 120 ms (N120), lo cual parece reflejar distinción inicial ortográfica y evaluación. Además, los pseudo-caracteres chinos provocaban una desviación ERP más positiva (P220) en comparación con los caracteres chinos entre 200-250 ms después de la aparición de los estímulos. Esto fue parecido a RP (potenciales de reconocimiento) y puede reflejar un proceso de integración del procesamiento fonológico y semántico basado en la información ortogr

, nous avons observé un plus grand effet du rôle paternel plus que maternel sur le lien entre le conflit et la croyance filiale réciproque atténuée ainsi qu'entre la menace perçue et les problèmes internalisés. Les implications pour la compréhension des processus de médiation responsables pour tous les effets indirects, même ceux qui sont accessoires, et le plus grand impact du conflit avec le père plus qu'avec la mère sont discutés. Les limites de l'étude et les considérations pour la recherche future sont aussi abordées. La investigación empírica ha demostrado que el conflicto entre padres e hijos está positivamente relacionado con pobre ajuste en adolescentes; no obstante, el proceso subyacente no ha sido examinado adecuadamente. Para explorar posibles caminos, se eligieron la creencia filial recíproca y la amenaza percibida con el objetivo de representar dos posibles mecanismos explicativos de cómo el conflicto padres-hijos daña la percepción de los adolescentes de su relación con los padres y su auto-percepción dentro de su marco de valoración cognitiva. El primero actúa atenuando el afecto de los hijos hacia los padres y el último bajando su auto-percepción. Este estudio también distingue los problemas interiorizados de los exteriorizados para examinar si la baja creencia filial recíproca es un mediador más fuerte de la relación entre el conflicto con los padres y los problemas exteriorizados de los adolescentes y si la amenaza percibida es un mediador más fuerte de la relación entre el conflicto con los padres y los problemas interiorizados de los adolescentes. Se han planteado las siguientes hipótesis: (1) cuanto más conflicto entre padres e hijos refieran los adolescentes, menor será el reconocimiento de la creencia filial recíproca, lo cual llevará a inadaptación, sobre todo, exteriorizada; (2) cuanto más conflicto entre padres e hijos refieran los adolescentes, mayor será la amenaza percibida, lo cual llevará a

subsurface devant être évaluée. Ceci permet de prendre des décisions plus pertinentes et pratiques. Dans cet article, certaines perspectives sur le développement d'approches «upscaling» (changement d' échelle) sont présentées, mettant en lumière des concepts mutli-échelles récents, en mettant de côté le problème du milieu fracturé. L'upscalling peut être utilisé comme un cadre utile pour gérer simultanément les problèmes d'échelle de travail, les approches stochastiques et les problèmes inverses. Les applications effectives et potentielles de l'upscalling sont mis en lumière, dans l'élaboration de modèles de subsurface contraints aux données observées, et la gestion des incertitudes et des études de sensibilité dans un cadre multi-échelle global. L'upscaling peut, en particulier, aider à trouver les paramètres qui contrôlent le comportement global de l'écoulement. Finalement, les approches par upscaling des équations non-linéaires de transport apparaissent comme une nouvelle frontière dans cette aire de recherche. Las formaciones geológicas son entidades complejas que resultan de procesos geológicos, mecánicos, y físico-químicos que ocurren en un rango muy amplio de escalas espaciales y escalas temporales. Los procesos de transporte que varían de la escala molecular a varios cientos de kilómetros pueden influenciar el comportamiento global del flujo de fluido en estas formaciones. Las heterogeneidades que cubren un rango amplio de escalas espaciales juegan un papel esencial para canalizar flujos de fluidos, especialmente cuando están acoplados con no linealidades inherentes a procesos de transporte en medios porosos. Estos asuntos tienen importancia práctica considerable en la gestión de aguas subterráneas, y en la industria petrolera, particularmente en la solución de problemas nuevos ocasionados por proyectos relacionados con el entrampamiento de CO2 en el subsuelo. Para gestionar esta complejidad uno tiene que priorizar

actividades humanas y por la propia explotación del acuífero. Sin embargo, en la práctica se suele considerar que hay sobreexplotación cuando se observan o se perciben ciertos resultados negativos de la explotación, tales como un descenso continuado del nivel del agua, un deterioro de su calidad, un encarecimiento del agua extraída, o daños ecológicos. Pero estos efectos no están necesariamente relacionados con el hecho de que la extracción sea mayor que la recarga, puesto que pueden ser simplemente el resultado de interferencias o del dilatado período transitorio que sigue a los cambios en los términos del balance de agua, y cuya duración depende del tamaño del acuífero, y de su permeabilidad y coeficiente de almacenamiento. Las extracciones del acuífero suponen una disminución del almacenamiento de agua subterránea durante este periodo transitorio. Para decidir que grado de "sobreexplotación del acuífero" es aconsejable o admisible hace falta la consideración detallada y actualizada de los efectos de la explotación y las medidas de corrección que se adopten. Para esa decisión no basta con reglas generales y el apoyo de algunas observaciones indirectas. Se necesitan observaciones de control, buen conocimiento del acuífero y cálculos o modelación del comportamiento, y todo ello en el marco de un conjunto de objetivos y políticas establecidas por una institución de gestión, con la implicación de aquellos que tienen un interés en el agua subterránea, y teniendo en cuenta los condicionantes ambientales y sociales. La sobreexplotación de acuíferos, que con frecuencia suele asociarse a algo éticamente malo, no tiene por qué ser necesariamente así durante cierto tiempo, sino una etapa en la evolución hacia un desarrollo sustentable. En la realidad la designación de sobreexplotación de acuíferos es principalmente un adjetivo que trata de calificar a una evolución preocupante bajo determinados puntos de vista, sin que tenga una significaci

eucaliptus en la década de 1950 y el uso más reciente de los acuíferos para riego y para abastecimiento de centros turísticos costeros han modificado el sistema de flujo del agua subterránea en esta zona. Este estudio se ha realizado en el sector occidental, llamado El Abalario. Se trata de una elevación suave situada entre el océano Atlántico y el arroyo de La Rocina. Debajo de un manto variable de arenas eólicas, que forma un alto cordón dunar costero, se encuentran sedimentos detríticos plio-cuaternarios formados por arenas silíceas finas, que hacia la base incluyen una capa de arenas gruesas y gravas de origen deltrico, los que a su vez yacen sobre margas. El flujo de agua subterránea está relacionado con niveles de gravas y gravillas semiconfinadas por las arenas fluvio-marinas que contienen el nivel freático. El nivel freático es somero excepto debajo del cordón dunar. Son frecuentes pequeñas lagunas temporales. Se ha simulado el flujo de agua subterránea en una sección para comprobar el modelo de flujo conceptual y la sensibilidad a variaciones de los parámetros. El modelo fue calibrado usando los valores de los parámetros hidráulicos obtenidos en ensayos de bombeo y datos piezométricos medidos a diferentes profundidades, y la descarga estimada al arroyo de La Rocina. La recarga de agua subterránea drena lateralmente, por un lado hacia la costa y por otro lado a través del arroyo de La Rocina, o directamente hacia las Marismas de Doñana situadas en el delta del río Guadalquivir. Con una lluvia media anual entre 550 y 600 mm, la recarga neta media estacionaria anual del acuífero, considerando periodos de tiempo largos, se estima entre 100 y 200 mm en las zonas de vegetación autóctona, y es notablemente menor en las zonas de plantación de eucaliptos. El modelo transitorio indica que la recarga varia espacialmente y no es claramente proporcional a la precipitación para periodos de un año. La evapotranspiración freática varia

ção máximas, principalmente em solos mais ácidos e pobres em matéria orgânico. A adubação fosfatada é muito importante no crescimento inicial da planta e, além de aumentar a produção de tuberculos em peso e números, aumenta também a quantidade e qualidade do amido neles contidos e reduz perdas durante o armazenamento dos mesmos. A quantidade de fósforo a aplicar dependerá da análise do solo considerando- se principalmente o nível de P existente e a textura do solo. Solos de textura média e arenosa necessitam maior conteúdo de fósforo do que os de textura argilosa para serem considerandos solos de baixo, médio ou alto teor de fósfato. Efeito da potássica Embora seja o elemento mais absorbido pela batateira, nem sempre há resposta positiva da aduba potássica sobre o rendimento da cultura. Provavelmente isto esteja relacionado com níveis elevados deste elemento no solo (Kurnik et all. 2001.). Entretanto, em solos com médios e baixos teores de potássio, aumentos significativos são conseguidos. Por isto, as recomendações de adubação com potássio, nas diversas regiões do mundo, variam de 50-300 kg ha-1 de K2O. Resultados de trabalhos em brasiléiros têm demonstrado que a aduba potássica pode ser substituída pela aplicação de 150 m3 ha-1 de vinhaça de cana de açúcar. Ao elevar- se a dose de fertilização potássica deverá haver precaução para que a adubação magnesiana seja suficiente. O K além de aumentar a produção, em solos deficientes, aumenta também o tamanho dos tubérculos produzidos, e a proporção de tubérculos grandes. Deficiência no suprimento de potássio á planta pode acarretar produção de tubérculos com elevada susceptibilidade aos danos mecánicos pós-colheita. Os tubérculos injuriados enegrecem facilmente e este enegrecimento é inversamente proporcional á quantidade de potássio nos tuberculos. Ademais, quando fritos dão origem a um produto escuro, de baixa valor comercial. Manejo de aduba
