    Carbonate fault breccia dykes in the Cerro La Chilca area, Eastern Precordillera, west-central Argentina, provide clues on the probable mechanism of both fault movement and dyke injection. Breccia dykes intrude Upper Carboniferous sedimentary rocks and Triassic La Flecha Trachyte Formation. The timing of breccia dyke emplacement is constrained by cross cutting relationships with the uppermost Triassic unit and conformable contacts with the Early Miocene sedimentary rocks. This study supports a tectonic-hydrothermal origin for these breccia dykes; fragmentation and subsequent hydraulic injection of fluidized breccia are the more important processes in the breccia dyke development. Brecciation can be triggered by seismic activity which acts as a catalyst. The escape of fluidized material can be attributed to hydrostatic pressure and the direction of movement of the material establishes the direction of least pressure. Previous studies have shown that cross-strike structures have had an important role in the evolution of this Andean segment since at least Triassic times. These structures represent pre-existing crustal fabrics that could have controlled the emplacement of the dykes. The dykes, which are composed mostly of carbonate fault breccia, were injected upward along WNW fractures.

    The Matagusanos-Maradona-Acequión Valley sits within the Andes Precordillera fold-thrust belt of western Argentina. It is an elongated topographic depression bounded by the roughly N-S trending Precordillera Central and Oriental in the San Juan Province. Moreover, it is not a piggy-back basin as we could have expected between two ranges belonging to a fold-thrust belt, but a very active tectonic corridor coinciding with a thick-skinned triangular zone, squeezed between two different tectonic domains. The two domains converge, where the Precordillera Oriental has been incorporated to the Sierras Pampeanas province, becoming the western leading edge of the west-verging broken foreland Sierras Pampeanas domain. This latter province has been in turn incorporated into the active deformation framework of the Andes back-arc at these latitudes as a result of enhanced coupling between the converging plates due to the subduction of the Juan Fernández ridge that flattens the Nazca slab under the South American continent. This study focuses on the neotectonics of the southern tip of this N-S elongated depression, known as Acequión (from the homonym river that crosses the area), between the Del Agua and Los Pozos rivers. This depression dies out against the transversely oriented Precordillera Sur, which exhibits a similar tectonic style as Precordillera Occidental and Central (east-verging fold-thrust belt). This contribution brings supporting evidence of the ongoing deformation during the Late Pleistocene and Holocene of the triangular zone bounded between the two leading and converging edges of Precordillera Central and Oriental thrust fronts, recorded in a multi-episodic lake sequence of the Acequión and Nikes rivers. The herein gathered evidence comprise Late Pleistocene-Holocene landforms of active thrusting, fault kinematics (micro-tectonic) data and outcrop-scale (meso-tectonic) faulting and folding of recent lake and alluvial sequences.

  9. Paleomagnetic study of Cambrian Ordovician rocks in the Eastern Precordillera of Argentina: some constraints on the Andean uplift of this block

    A paleomagnetic study on several carbonatic units (limestones to dolomites) of the Argentine Precordillera, spanning the Middle Cambrian to Arenig, is reported. Sampling was done at 23 sites (140 samples) in five localities of the Eastern Precordillera of San Juan province: Zonda (1), Juan Pobre (2) and La Flecha (3) creeks, Loma Redonda (4) and Cerro Pedernal de los Berros (5). Standard AF and thermal demagnetization indicated two different magnetic behaviors. Samples from localities 1 and 2 showed a single, post-tectonic magnetic component attributed to a Recent viscous or chemical remagnetization. Samples from localities 3 to 5 showed two magnetic components: a low unblocking temperature (350°C) magnetization coincident with that found at the previous localities and a high temperature one (up to 500°C). This second component was also found to be post-folding (post-Devonian?) and its in situ mean direction is Dec: 277.1°, Inc: 69.4, α95: 9.3°, N=10. This is not consistent with any expected direction for the study area between Carboniferous and Recent times. It is therefore inferred that the rocks carrying it underwent substantial tectonic rotation since its recording. Comparison with the magnetization carried by similar Early Ordovician limestones in the Central Precordillera and the San Rafael Block, and assigned to a Permian remagnetizing event, suggests that the same process affected the carbonatic rocks in the Eastern Precordillera and, therefore, the age of the component is likely Permian. Restoration of the in situ mean direction to the expected direction for a Permian remagnetization can be obtained by a 40° ccw rotation around an axis plunging 30° to N30°E. This is compatible with uplifting of the Eastern Precordillera as a series of quasi-rigid blocks along a major E dipping N to NE backthrust during the Andean orogeny.

    Full Text Available The Andean foreland of western Argentina (28°S-33°S corresponds to retroarc deformations associated with the ongoing flat subduction of the Nazca plate beneath the South American lithosphere. This region is characterized by high levels of seismic activity and crustal active faulting. To improve earthquake source identification and characterization in the San Juan region, data from seismology, structural geology and quantitative geomorphology were integrated and combined to provide a seismotectonic model. In this seismotectonic model, the Andean back-arc of western Argentina can be regarded as an obliquely converging foreland where Plio-Quaternary deformations are partitioned between strike-slip and thrust motions that are localized on the E-verging, thin-skinned Argentine Precordillera, and the W-verging thick-skinned Sierras Pampeanas, respectively. In this seismotectonic model, the Sierra Pie de Palo appears to be a key structure playing a major role in the partitioning of the Plio-Quaternary deformations.

    At the northern sector of the Precordillera Sur (31° 50'-32° 40' SL/68° 45'-69° 20' WL), Central Andes of Argentina, NW-trending sinistral transpressive shear zones at different scales, product of the Late Cenozoic Andean deformation, are recognized. The most significant of them is the 120 km long Barreal-Las Peñas Belt and within it, a small-scale (7 km long) Quaternary sinistral transpressive shear zone, called Los Avestruces, has been detected from geomorphological and geophysical analysis (32° SL/69° 21 WL). Geophysical techniques were applied to better characterize the shallow structure and kinematics of some representative structures in this shear zone. In particular, the use of tomography of electrical resistivity methods allowed characterizing the subsurface geometry of some areas of interest, enabling the recognition of Quaternary layers against their original slope, the geometry of the reverse fault which uplifted the Pleistocene deposits of one of the highs, the geometry of a likely previous extensional fault reactivated and inverted during the Quaternary as well as the presence of a reverse blind fault, which has uplifted the Quaternary deposits of the Los Avestruces bog. The location of the above mentioned shear zones coincides with the northern branch of the NW-trending extensional Triassic Cuyana basin. Thus, their presence appears to be related to Andean reactivation of older (Triassic), mainly NW-trending, structures. In the northern area of the Precordillera Sur, as well as in other places of the world here discussed, these kinds of paleotectonic oblique features play a major role in defining the geometry and kinematics of Late Cenozoic deformation.

  14. Faulting and erosion in the Argentine Precordillera during changes in subduction regime: Reconciling bedrock cooling and detrital records

    Science.gov (United States)

    Fosdick, Julie C.; Carrapa, Barbara; Ortíz, Gustavo

    2015-12-01

    The Argentine Precordillera is an archetypal retroarc fold-and-thrust belt that records tectonics associated with changing subduction regimes. The interactions between exhumation and faulting in the Precordillera were investigated using apatite and zircon (U-Th-Sm)/He and apatite fission track thermochronometry from the Precordillera and adjacent geologic domains. Inverse modeling of thermal histories constrains eastward in-sequence rock cooling associated with deformation and erosion from 18 to 2 Ma across the Central Precordillera tracking thrusting during this time. The youngest AHe ages (5-2 Ma) and highest erosion rates are located in the eastern and western extremities of the Precordillera and indicate that recent denudation is concentrated at its structural boundaries. Moreover, synchronous rapid Pliocene cooling of the Frontal Cordillera, Eastern Precordillera, and Sierra del Valle Fértil was coeval with initiation of basement-involved faulting in the foreland. Detrital zircon U-Pb geochronology from the ca. 16-8.1 Ma Bermejo foreland basin strata suggests fluvial connectivity westward beyond the Frontal Cordillera to the Main Cordillera and Coast Range followed by an important shift in sediment provenance at ca. 10 Ma. At this time, we suggest that a substantial decrease in Permo-Triassic igneous sources in the Frontal Cordillera and concurrent increase in recycled zircons signatures of Paleozoic strata are best explained by uplift and erosion of the Precordillera during widening of the thrust-belt. Bedrock thermochronology and modeling indicate a 2-6 Myr lag time between faulting-related cooling in the hinterland and the detrital record of deformation in the foreland basin, suggesting that for tectonically active semi-arid settings, bedrock cooling may be more sensitive to onset of faulting. We suggest that high erosion rates in the Frontal Cordillera and Eastern Precordillera are associated with increased interplate coupling during shallowing of the

    Full Text Available En la región, ubicada al norte del río San Juan, 31°30'S y 68°30'O, parte distal del piedemonte oriental de la Precordillera Oriental, sector La Laja - El Salado, se encontró la presencia de piping en sedimentos y sedimentitas finas rosadas pertenecientes a secuencias neógenas. Se investigan los condicionantes y factores que favorecieron su génesis. Se interpreta, que este proceso es la causa principal de la formación del relieve erosivo con desplomes, hundimientos, caída de rocas en ladera y de la erosión retrocedente existente en las cabeceras y base de los barrancos. Se analizan los distintos factores ambientales: climáticos, litológicos y estructurales de la región. Entre los condicionantes favorables resultan: la presencia de sedimentos y afloramientos de argilitas con muy altos contenidos en sodio, en un clima árido-seco con amplia variación estacional de precipitaciones. Además, la actividad neotectónica presente en ese sitio coadyuva mediante la emergencia de agua subterránea con alta mineralización a contaminar los afloramientos de argilitas. El piping resulta ser entonces, en esta región árida y con actividad neotectónica, un peligro subsuperficial para tener en cuenta en la planificación territorial.Piping process in fine-grained, pink coloured Neogene sediments and sedimentary rocks were studied in the La Laja-El Salado area, northern Río San Juan, in the distal and eastern piedmont of the Eastern Precordillera. Conditions favourable to the genesis of piping were investigated through aerial photo interpretation and fieldwork, and it was concluded that the factors controlling its occurrence are lithology, climate, structure and landscape. The piping in the study area took place mainly in fine clayey materials, with very high values of sodium, and in a dry and arid climatic environment. Neotectonic activity is particularly important for evaluation of the piping processes: some erosional geomorphological features

Aunque el terremoto causó un daño considerable a San Juan, la fuente del terremoto permanecía incierta. Fuentes potenciales de falla ocurren en las fajas plegadas y corridas adyacentes, la epidérmica de la Precordillera o la faja de basamento de Sierras Pampeanas, al oeste y este respectivamente de la sierra de Villicum, una lámina de corrimiento de la Precordillera Oriental, ubicada al noroeste de la provincia de San Juan. La sierra de Villicum es una lámina de corrimiento limitada al oeste por el corrimiento de Villicum, que yustapone un panel de estratos cambro-ordovícicos y neógenos de la pared colgante, con estratos rojos neógenos en la pared yaciente.

    @@ Present work demonstrates that a level equivalent to the proposed Whiterockian basal GSSP can be located graphically in a composite section anchored by the Niquivil section of the Argentine Precordillera. The FAD of Cooperignathus aranda in the Niquivil composite section, a candidate for GSSP of the Lower/Middle Ordovician boundary, projects to a level very close to the FAD of Tripodus laevis in the Whiterockian reference section. The conodont-based framework reported here includes the potential for recognition of the proposed Whiterock Canyon-based GSSP, the Cooperignathus aranda-based GSSP, and, possibly, the Baltoniodus triangularisbased GSSP, recently proposed.

Se intentará evaluar el uso social de la justicia que emprendieron los miembros de la comunidad, a partir de la instrumentalización del concepto de bandidaje, reformulando judicialmente la dinámica de sus antagonismos interpersonales. Sin embargo, esta experiencia habría sufrido puntos de inflexión en la medida que las justicias locales permeabilizaban la presión por imponer una burocracia judicial, impulsada por el Estado a lo largo del siglo. La paulatina subordinación letrada de las instancias judiciales legas, irían resintiendo la maleabilidad con la que los vecinos del sector pleiteaban en la justicia criminal, pues se impondrían definiciones de bandidaje de acuerdo a la legislación penal que iba promulgándose.

    Mass removal via erosion is an important process that interacts with deformation in convergent mountain belts such as the Andes, and improved quantification of denudation is critical for elucidating spatio-temporal patterns of deformation. We report new apatite and zircon (U-Th)/He (AHe, ZHe) and apatite fission track (AFT) results from the Precordillera of Argentina that record Neogene fault-related unroofing during growth of the Andean retroarc fold-and-thrust belt. The Precordillera fold-and-thrust belt of Argentina is located west of the thick-skinned Sierras Pampeanas and evolved concurrently with the Bermejo retroarc foreland basin since at least the early Miocene. At the Rio Jáchal latitude (30°S), most crustal shortening associated with the Andean orogen is accommodated across the Precordillera, however, its unroofing record remains poorly constrained. Here we test the relationships between thrust faulting and exhumation and quantify the erosional input of sediments to the foreland basin. ZHe samples from Silurian-Carboniferous metasedimentary rocks collected across the Rio Jáchal transect yield entirely Permo-Triassic cooling ages, indicating that the present-day erosional depth of the Precordillera has resided above the ZHe partial retention zone (PRZ) throughout Mesozoic-Cenozoic time. Preliminary AFT data of the Precordillera also indicate mixed pre-Cenozoic ages. ZHe and AFT ages provide a nominal Iglesia piggy-back basin and the Las Salinas anticline at the eastern boundary between the Precordillera and Pampean craton. Apatite AHe and AFT data from the western Sierras Pampeanas indicate cooling through both AHe and AFT PRZs between ~5-4 Ma and suggest rapid exhumation during faulting of the Sierra de Valle Fértil. These data suggest a higher magnitude of Miocene exhumation of the Sierras Pampeanas compared to the Precordillera. Miocene exhumation rates across the Precordillera range from 0.16 to 1.11 mm/yr, with highest rates concentrated along

    New data from the Argentine Precordillera in the southern Central Andes document changes in depositional environment and sediment accumulation rates during Upper Cretaceous through Oligocene basin evolution, prior to the onset Miocene foredeep sedimentation. This work presents new sedimentology, detrital geochronology, and geologic mapping from a series of continental strata within this interval to resolve the timing of sedimentation, nature of depositional environments, and basin paleogeography at the nascent phase of Andean orogenic events, prior to the uplift and deformation of the Precordillera to the west. Five stratigraphic sections were measured across both limbs of the Huaco Anticline, detailing sedimentology of the terrestrial siliciclastic upper Patquía, Ciénaga del Río Huaco (CRH), Puesto la Flecha, Vallecito, and lower Cerro Morado formations. Paleocurrent data indicate a flow direction change from predominantly NE-SW in the upper Patquía and the lower CRH to SW-NE directed flow in the upper CRH, consistent with a large meandering river system and a potential rise in topography towards the west. This interpretation is further supported by pebble lag intervals and 1-3 meter scale trough cross-bedding in the CRH. The thinly laminated gypsum deposits and siltstones of the younger Puesto la Flecha Formation indicate an upsection transition into overbank and lacustrine sedimentation during semi-arid climatic conditions, before the onset of aeolian dune formation. New maximum depositional age results from detrital zircon U-Pb analysis indicate that the Puesto la Flecha Formation spans ~57 Myr (~92 to ~35 Ma) across a ~48 m thick interval without evidence for major erosion, indicating very low sedimentation rates. This time interval may represent distal foredeep or forebulge migration resultant from western lithospheric loading due to the onset of Andean deformation at this latitude. Detrital zircon U-Pb age spectra also indicate shifts in sediment routing

    Widespread clockwise rotations in Mesozoic and Lower Tertiary rocks of northern Chile have been interpreted as the sum of two rotational events separated in time: an early rotation related to local deformation plus a late rotation related to wholesale rotation of northern Chile linked to Late Cenozoic oroclinal bending in the Central Andes. In this paper we report new paleomagnetic data from Cretaceous, upper Oligocene and Miocene sedimentary rocks in the Precordillera of northern Chile. The results suggest that all these rocks acquired their remanence at or close to the time of deposition. The lack of rotation in undeformed lower Miocene strata clearly indicates that clockwise rotations found in underlying, faulted and folded Cretaceous rocks were completed before the Late Cenozoic. Results from nearby localities in deformed upper Oligocene strata would argue for little (˜5°) rotation since the late Oligocene. Data from widely separated Miocene localities covering an area of about 5000 km 2 in the Calama basin strongly suggest that northern Chile did not undergo significant wholesale rotation during the Late Cenozoic. This, together with previous paleomagnetic evidence against Neogene rigid-body-like rotation of the southern Peruvian forearc, suggests that the curved shape of the Central Andean forearc was not significantly enhanced during the Late Cenozoic. By inference, all of the rotation in most Mesozoic and Lower Tertiary rocks of northern Chile was accomplished in the Cretaceous and/or Early Cenozoic, when the locus of deformation in the Central Andes was localized in the present forearc region.

  11. Reinterpretation of the Ordovician rotations in NW Argentina and Northern Chile: a consequence of the Precordillera collision?

    Early Paleozoic paleomagnetic data from NW Argentina and Northern Chile have shown large systematic rotations within two domains: one composed of the Western Puna that yields very large (up to 80°) counter-clockwise rotations, and the other formed by the Famatina Ranges and the Eastern Puna that shows (~40°) clockwise rotations around vertical axes. In several locations, lack of significant rotations in younger rocks constrains this kinematic pattern to have occurred during the Paleozoic. Previous tectonic models have explained these rotations as indicative of rigid-body rotations of large para-autochthonous crustal blocks or terranes. A different but simple tectonic model that accounts for this pattern is presented in which rotations are associated to crustal shortening and tectonic escape due to the collision of the allochthonous terrane of Precordillera in the Late Ordovician. This collision should have generated dextral shear zones in the back arc region of the convergent SW Gondwana margin, where systematic domino-like clockwise rotations of small crustal blocks accommodate crustal shortening. The Western Puna block, bordering the Precordillera terrane to the north, might have rotated counterclockwise as an independent microplate due to tectonic escape processes, in a fashion similar to the present-day relationship between the Anatolia block and the Arabian microplate.

    In central-western Argentina, an Early Paleozoic belt including mafic-ultramafic bodies, marine metasedimentary rocks and high-pressure rocks occur along the western margin of the Precordillera and in the Frontal Cordillera. First pressure-temperature estimates are presented here for low-grade rocks of the southern sector of this belt based on two metasedimentary and one metabasaltic sample from the Peñasco Formation. Peak metamorphic conditions resulted within the range of 345-395 °C and 7.0-9.3 kbar within the high-pressure greenschist facies. The corresponding low metamorphic gradient of 13 °C/km is comparable with subduction related geothermal gradients. Comparison between these results and data from other localities of the same collision zone (Guarguaraz and Colohuincul complexes) confirms a collision between Chilenia and the composite margin of western Gondwana and suggests a stronger crustal thickening in the south of the belt, causing exhumation of more deeply buried sequences. During the Early Paleozoic a long-lived marine sedimentation coupled with the intrusion of MORB-like basalts occurred along a stable margin before the collision event. This contrasts with the almost contemporaneous sedimentation registered during accretion in accretionary prism settings and additionally proves the development of a collision zone along western Precordillera and the eastern Frontal Cordillera as well as the existence of Chilenia as a separate microcontinent.

    Collision of the down-going, Laurentia-derived Argentine Precordillera terrane with the Gondwanan margin drove the Ordovician Ocloyic orogeny, including subduction volcanism, metamorphism, and top-to-west shearing east of the Precordillera. In the Precordillera, above passive-margin carbonates (Lower Ordovician San Juan Limestone and older carbonates), a Middle to Upper Ordovician westward-prograding synorogenic clastic wedge of black shale (Gualcamayo Shale) and coarser clastic sediment (Las Vacas Conglomerate and Trapiche Formation) fills a peripheral foreland basin. New research has identified vestiges of a west-directed thin-skinned Ocloyic foreland thrust belt that has been fragmented by east-directed Andean thrusting. The El Corral thrust sheet, with hanging-wall detachment in the San Juan Limestone, extends over a west-directed footwall frontal ramp and extensive flat to low-angle footwall cutoff in the Gualcamayo and Las Vacas formations. Las Vacas conglomerates in the footwall include olistoliths (10-m scale) exclusively of San Juan Limestone and Gualcamayo Shale; the beds in some olistoliths are folded. The advancing El Corral thrust sheet successively supplied and overrode the stratigraphically restricted olistoliths. In the El Corral footwall, tight west-vergent folds and faults within an anticlinorium in the San Juan Limestone and Gualcamayo Shale suggest a deeper (unexposed) thrust fault, the Los Celestitos fault. West of the anticlinorium, easterly dip (restored to remove Andean deformation) beneath an angular unconformity between Las Vacas and Trapiche beds is consistent geometrically with the trailing limb of a west-vergent fault-propagation anticline in the hanging wall of the subsurface Los Celestitos fault. The same angular unconformity truncates the El Corral fault and hanging-wall strata. In the Trapiche Formation, contrasting sedimentary facies from sandy turbidites westward to limestone-clast megabeds and olistoliths suggest another frontal

    . 35º- 40° obtenida en los afloramientos de la quebrada El Salto, se infiere en forma preliminar una importante componente sinestral durante la extensión en el tramo norte de la cuenca.Triassic clastic and volcanic rocks from the Precordillera were deposited in the Cuyana rift basin filling half-graben systems. Contractional/ transpressional Andean tectonics leads to the almost complete inversion of some portions of the basin which resulted in present-day isolated, structurally controlled outcrops of these Triassic rocks. In the Southern Precordillera both the degree of Neogene tectonic inversion and structural compexities are variable. At the regional scale, these variations in Andean deformation are related to first order anisotropies like the Cuyana basin borders and previous shear zones of Permian age (San Rafael orogenic phase. This paper focuses on the kinematic analysis done in the Cerro Manantial thrust sheet area (Cordón San Bartolo, central sector of the South Precordillera where tectonic inversion was not that strong and the influence of oblique strain zones is practically null. Four sets of extensional / transtensional faults were recognized affecting Triassic sedimentary rocks of the El Cielo Formation (Uspallata Group at the Quebrada El Salto. Fault displacements are of decimetric to metric scale. Mesoscopic kinematic indicators (en-échèlon tensional gashes, Riedel shear fractures, sigmoidal fractures were measured.

    extends over an area of about 3,500 km2 centered in the San Juan city. Ten years of gravity periodic measurements have allowed to evaluate the speeds of the gravitational intensity field variations. These gravity changes adjust reasonably well with the statistical lineal regression model applied to the gravity versus time observations. The observed data support the current uplift of the Eastern Precordillera, reflected in increases of gravity (g in all bench marks located westwards of the Villicum-Ullum-Zonda fault and in the decrease of gravity eastwards of this structure. We identify three segments of larger activity: a La Laja fault with strong decreases of g, b Maradona-Cerro Bayo segment, with increases of g westwards of the Sierra Chica de Zonda and c decreases of g at La Rinconada fault. The data show tectonic activity in the Tulum faults system, gravity changes have lined up in the Cerro Valdivia-Cerro Barboza-Sierra de Pie de Palo lineament and increase to the east. The largest variations are observed eastwards of the Barboza hill with a minimum of g. Magnetic and gravity anomaly maps indicate basement patterns consistent with these active structures.

    Full Text Available En la región, ubicada al norte del río San Juan, 31°30'S y 68°30'O, parte distal del piedemonte oriental de la Precordillera Oriental, sector La Laja - El Salado, se encontró la presencia de piping en sedimentos y sedimentitas finas rosadas pertenecientes a secuencias neógenas. Se investigan los condicionantes y factores que favorecieron su génesis. Se interpreta, que este proceso es la causa principal de la formación del relieve erosivo con desplomes, hundimientos, caída de rocas en ladera y de la erosión retrocedente existente en las cabeceras y base de los barrancos. Se analizan los distintos factores ambientales: climáticos, litológicos y estructurales de la región. Entre los condicionantes favorables resultan: la presencia de sedimentos y afloramientos de argilitas con muy altos contenidos en sodio, en un clima árido-seco con amplia variación estacional de precipitaciones. Además, la actividad neotectónica presente en ese sitio coadyuva mediante la emergencia de agua subterránea con alta mineralización a contaminar los afloramientos de argilitas. El piping resulta ser entonces, en esta región árida y con actividad neotectónica, un peligro subsuperficial para tener en cuenta en la planificación territorial.

Muchas de estas estructuras eo y neopaleozoicas fueron reactivadas posteriormente durante los sucesivos episodios de deformación. El análisis cinemático de las estructuras eopaleozoicas permitió distinguir dos eventos de deformación con características cinemáticas distintas. El primer evento, D1, posee una dirección de acortamiento máximo E-O y vergencia occidental. El segundo evento, D2, posee una dirección de acortamiento máximo NO a ONO y doble vergencia. Dos modelos permiten explicar estas variaciones cinemáticas; o bien los dos eventos de deformación se encontraron separados en el tiempo y responde a dos eventos tectónicos distintos, o corresponden a un mismo evento tectónico transpresivo con rotaciones en las direcciones de acortamiento a través del tiempo. La deformación paleozoica tardía, de edad pérmica, se caracteriza por la generación de una faja plegada y corrida de piel fina en el sector oriental y de piel gruesa en el sector occidental, producto de la reactivación de estructuras eopaleozoicas. El análisis cinemático indica una dirección de acortamiento NO-SE y doble vergencia.

La litoestratigrafía y la bioestratigrafía son ensambladas en un modelo paleogeográfico no palinspástico coincidente con la actual distribución del basamento precámbrico expuesto en las Sierras Pampeanas Occidentales. La asociación de biofacies y litofacies reconocidas en toda la cuenca cámbrica precordillerana permiten interpretar una plataforma con margen y es posible distinguir tres grandes áreas que corresponden a una plataforma interna, una plataforma externa y una zona donde las dos anteriores se interdigitan con un talud superior y con una barrera marginal. Durante el Cámbrico inferior tardío se inició una etapa de rifting con sedimentación siliciclástica y evaporítca dentro de un graben intracontinental que evolucionó hacia una plataforma abierta. Se detecta un hiatus faunístico en el límite Cámbrico inferior-Cámbrico medio correlacionable con el evento regresivo Hawke Bay de Los Apalaches. En el Cámbrico medio tardío se instaló una plataforma restringida con lagoon, barreras internas, terrígenos internos y sabkha costero desarrollados en el E de la Precordillera, mientras que barreras marginales y una plataforma externa se desarrollaban en el O de la Precordillera. Durante el Cámbrico superior una amplia plataforma perimareal progradaba hacia el O limitada por barreras marginales en el S de la cuenca, mientras que en el N se manifestaba con una menor restricción. Cerca del límite Cámbrico-Ordovícico una nueva plataforma con margen retrogradaba hacia el E como consecuencia de un evento de inundación de la cuenca. Durante el Cámbrico superior comenzaba a manifestarse un colapso tectónico distensivo en el S de la cuenca que luego se generalizaría en toda la Precordillera durante el Ordovícico.

Asimismo los valores más bajos de Vp son consistentes con material de tipo aluvional situado en las capas sísmicas más superficiales (< 7m de profundidad. Otras unidades relevadas en el terreno indican afloramientos de diabasas y gabros, los cuales no han sido explorados geofísicamente. Sin embargo, a partir de la comparación de las litologías y velocidades sísmicas Vp observadas con bases de datos globales, es posible predecir la continuación en profundidad de las litologías máficas con velocidades sísmicas de Vp aún mayores que aquellas determinadas en superficie. Estos resultados son de interés debido a que ayudan a identificar una posible faja ofiolítica en Precordillera, en un sector donde el espesor cortical actual estimado en 64 km aproximadamente, estaría engrosado.

    Full Text Available El Complejo Ígneo Gualcamayo comprende un conjunto de intrusivos y diques de composición riodacítica a andesítica que se encuentra en el área del distrito minero homónimo, ubicado en la Precordillera Central sanjuanina, sobre el segmento de subducción subhorizontal de los Andes Centrales (28º a 33º S. Sus características de yacencia, composición modal y litogeoquímica complementadas con edades radimétricas existentes indican que son producto de un pulso magmático que tuvo lugar en el Mioceno superior (~9 Ma. El mismo corresponde a un magmatismo de arco emplazado en una corteza de espesor normal en transición a una de espesor intermedio (~45 km. Asociado a este evento se reconoce importante actividad hidrotermal que dio origen principalmente a alteración potásica (feldespato potásico-cuarzo-biotita-magnetita y, en forma subordinada, propilítica la cual podría ser producto de un sistema tipo pórfiro. El carácter oxidante de este magmatismo sugiere que podría tener un potencial mineralizante para la generación de depósitos de tipo cobre porfírico. Por otra parte afloran en el área filones capa andesíticos cuyas características geoquímicas indican que habrían sido formados por un magmatismo de arco emplazado en una corteza de espesor normal (~30 km. Estas rocas por su yacencia y petrografía, podrían correlacionarse con la facies andesítica del Grupo del Áspero, de edad miocena inferior (17-18 Ma.

    Full Text Available After a typical passive margin setting during the Cambrian, two basically different tectofacies evolved simultaneously and mostly independently during the Ordovician in the Argentinean Precordillera basin. The eastern domain characterizes epicontinental depositional systems developed on a stable margin, while the western domain is composed of deep-sea turbiditic systems which developed on a high subsidence «cuasioceanic» substratum. The two domains were set aside during the Ocloyic movements and later tectonic phases of the Caledonic cycle. A regional unconformity developed by upwarping of the former platform (eastern domain conforms the downlaping surface of the Late Ordovician and Silurian siliciclastic shallow marine sequences. This regional doming is interpreted as a peripheral bulge in an incipient foreland basin caused by a type A subduction to the present west. This hypothesis is quite different from former ones and solves most of the stratigraphic and architectural problems during the Ordovician and Silurian Silurian and Devonian depocenters are mainly localized on the eastern domain and conform a succession of shallow marine sequences, which commonly characterize forelands. The different unconformities affecting the Silurian and Devonian deposits are interpreted as basin relaxation periods and as global sea-level oscillations. The Late Devonian Chanic diastrophysm involved an important shortening (definitive annexation of the two domains and caused the main paleogeographic rearrangement, supported by the regional angular unconformity which separates the Lower Palaeozoic from the Upper Palaeozoic continental deposits.Desde un punto de vista regional, el Sistema Ordovícico de la Precordillera del centrooeste argentino puede subdividirse en dos tectofacies que habrían evolucionado paralelamente y en contextos casi independientes una de otra, acreccionadas durante la Orogenia Oclóyica y fases posteriores del Ciclo Caledónico.

    Full Text Available Geological characteristics of the dacitic porphyries and their host rock, Quebrada del Peñasquito, western Precordillera of San Juan. At Peñasquito creek, in the sierra del Tontal (S 31º 40’ 44,5” - W69º 14’ 05”, western San Juan province, at an altitude of 2,953 m.s.n.m, a succession of dacitic dykes of unknown age are recognized, intruding subconcordantly sandstones of the Don Polo Formation of Ordovician age. The sandstones intruded by the dykes present short wavelength symmetrical folding (400 m. The dikes have attitudesof N0º/85ºO-N30º/75ºO, with thicknesses ranging between 3 and 25 m. Microscopically, they present a porfiric texture, composed of quartz, plagioclase, biotite and hematite. A deep alteration (oxidation confers a yellowish color to the dykes, easily visible by means of satellite imagery. There are numerous folded veins of quartz thataccompany the dikes, associated to anticline folds, fractures and shear zones, with sigmoid structures and cinematic indicators with dextral displacement indicators.The dikes may correspond to a Permian-Triasic or Miocene magmatism. The closest dacitic magmatism of Permian age has been recognized to the south of the area, in Pampa de los Pozos and Yalguaraz, with copper mineralization. However, Peñasquito´s dykes have a greater similarity with dacitic dikes described at Carrizal creek, 7 km to the north of the study area. For this reason are assigned to the Miocene magmatism recognized in the region.Exploratory studies are suggested to determine the presence of mineralization.

    2010-03-01

    Full Text Available La estructura del sector austral de la Precordillera es el resultado de una compleja serie de eventos de deformación superpuestos: eopaleozoicos, neopaleozoicos, permo-triásicos y cenozoicos, cada uno caracterizado por estructuras con rumbos, vergencia y estilos propios. Muchas de estas estructuras eo y neopaleozoicas fueron reactivadas posteriormente durante los sucesivos episodios de deformación. El análisis cinemático de las estructuras eopaleozoicas permitió distinguir dos eventos de deformación con características cinemáticas distintas. El primer evento, D1, posee una dirección de acortamiento máximo E-O y vergencia occidental. El segundo evento, D2, posee una dirección de acortamiento máximo NO a ONO y doble vergencia. Dos modelos permiten explicar estas variaciones cinemáticas; o bien los dos eventos de deformación se encontraron separados en el tiempo y responde a dos eventos tectónicos distintos, o corresponden a un mismo evento tectónico transpresivo con rotaciones en las direcciones de acortamiento a través del tiempo. La deformación paleozoica tardía, de edad pérmica, se caracteriza por la generación de una faja plegada y corrida de piel fina en el sector oriental y de piel gruesa en el sector occidental, producto de la reactivación de estructuras eopaleozoicas. El análisis cinemático indica una dirección de acortamiento NO-SE y doble vergencia. Durante la etapa extensional, desde el Pérmico Tardío hasta Triásico Medio, la región sufrió una deformación transtensional producto de una dirección de extensión NE y la reactivación de una zona de debilidad previa de rumbo NNO. Las estructuras pre-ándicas han sido reactivadas durante la orogenia ándica generando una faja plegada y corrida de piel gruesa con doble vergencia.

    Full Text Available La Precordillera Sur y las Cerrilladas Pedemontanas de Mendoza, son dos unidades morfotectónicas principales en la vertiente oriental de los Andes centrales, a los 31º30' - 33º30' de latitud sur. Allí, dos cinturones de deformación transpresiva y orientación noroeste, denominados fajas Barreal-Las Peñas y Río Mendoza-Tupungato, se desarrollaron como consecuencia de la gradual somerización de la placa de Nazca en los últimos 20 Ma. Su orientación y compleja geometría estructural resulta de la interferencia de la deformación andina tardío-cenozoica con la estructura de orientación noroeste del rift triásico de la cuenca Cuyana y antiguas zonas de sutura colisional de edad paleozoica. Este trabajo demuestra que los rasgos paleotectónicos del substrato triásico-paleozoico de la Precordillera Sur y del margen oriental de la Cordillera Frontal controlan la configuración morfotectónica y la distribución y reactivación de gran parte de la estructura neotectónica del margen andino a estas latitudes.The Southern Precordillera and Cerrilladas Pedemontanas of Mendoza, Argentina, are two major morphotectonic units in the eastern side of the Central Andes at 31º30' - 33º30' South latitude. There, two regional NW striking structures, called the Barreal - Las Peñas and Río Mendoza - Tupungato belts were developed as a consequence of gradual flattening of the Nazca plate in the last 20 M.yrs. Their orientation and complex structural geometry result from the interference of the Late Cenozoic Andean deformation with the NW-trending rift structure of the Triassic Cuyo basin and ancient collisional suture zones of Paleozoic age. This work demonstrates that paleotectonics features in the Triassic-Paleozoic substratum of the Southern Precordillera and the eastern margin of the Cordillera Frontal control the morphotectonic configuration and neotectonic structural distribution and rejuvenation of the Andes at these latitudes.

  11. The Relationship Between the Surface Expression of Blind Thrust Faults and Crustal-Scale Deformation in the Eastern Precordillera, San Juan, Argentina

    Large earthquakes (M w 6.5+) are often accompanied by surface rupture that has a predictable relationship with the magnitude. However, in large thrust earthquakes that have a deep (30+ km) hypocenter or fault tip, coseismic surface deformation is expressed primarily by folding rather than as rupture along the fault surface. Knowledge of source characteristics and surficial geology are required to characterize the relationship between earthquake fault slip and coseismic folding. By fully identifying and characterizing the fault plane of the M w 7.4 earthquake that occurred in 1944 in the eastern Precordillera of the Andes, destroying the city of San Juan in northwestern Argentina, we seek to relate active folding in the near-surface structures to the blind-thrust fault at depth. Coseismic deformation associated with the 1944 earthquake are secondary fault-related folding features, and there is a large discrepancy between the amount of surface rupture and the magnitude. Subtle fold-related clues at the surface represent the only potential for recognition of the occurrence of past earthquakes. This two-part study employs seismology and structural mapping to provide a new image of the Eastern Precordillera at the crustal scale. Source parameter inversion of teleseismic seismograms from the 1944 event place the hypocenter on a west-dipping plane approximately 30 km deep, which has previously been defined by microseismicity, as opposed to a surface-rupturing event in the Neogene sedimentary strata. Preliminary results from field mapping show two types of folding due to a west-dipping thrust fault with a tip at 5 km depth: a broad long-wavelength fold (~8 km) in deformed strath terraces cut into previously deformed bedrock, and short wavelength folding and faulting in the bedrock in the form of reactivation of older thrust planes. As of now, we cannot uniquely tie any one of these surficial structure to the thrust fault at depth because the pre-existing deformation in the

    Full Text Available La Formación Punta del Agua en el extremo noroccidental de la cuenca Paganzo, representa las primeras manifestaciones de actividad volcánica neopaleozoica en la Precordillera y en las Sierras Pampeanas. La variedad litológica de esta unidad comprende interestratificación de flujos lávicos, flujos piroclásticos y acumulaciones sedimentarias. Los flujos lávicos fueron divididos según su composición y textura; se incluyó en esta agrupación un filón capa de composición dacítica. Los flujos piroclásticos fueron subdivididos para su caracterización en depósitos gruesos de flujos de bloques y cenizas y reoignimbritas. Durante los períodos intereruptivos tuvo lugar la sedimentación de conglomerados volcánicos, arenitas líticas volcánicas y escasos niveles pelíticos; todas estas rocas conforman litosomas fuertemente lenticulares que reflejan la irregularidad morfológica del campo volcánico. Las características geoquímicas de las volcanitas fueron analizadas sobre la base de doce muestras provenientes de ambos flancos del sinclinal de Punta del Agua. Los valores obtenidos corresponden al espectro de rocas mesosilíceas y ácidas, desde andesitas basálticas hasta riolitas, aunque claramente dominan las composiciones andesíticas. El carácter calcoalcalino de estas rocas, y la abundancia relativa en K de las andesitas, sugieren líquidos padres originados en zonas de subducción con efectos de procesos de cristalización fraccionada y contaminación sobreimpuestos. En lo que corresponde a la antigüedad de la unidad ha sido establecida a partir de sus relaciones estratigráficas y dataciones radimétricas; ambas líneas de investigación sugieren una edad carbonífera superior para el conjunto, aunque sin descartar que sus términos cuspidales alcancen el Pérmico más temprano.The Punta del Agua Formation (north-west Paganzo Basin represents the earliest manifestation of Neopalaeozoic volcanism in the Precordillera and Sierras

    Full Text Available En la región del antepaís andino en la provincia de La Rioja (28º31'S - 68º30'W aflora una faja de deformación dúctil con orientación NW, parcialmente expuesta en el río Bonete, conocida con el nombre de faja de deformación de Jagüé. Trabajos previos sugieren que constituiría el límite norte del terreno de Precordillera. Está fundamentalmente compuesta por ortoanfibolitas intensamente foliadas que gradan a gabros, granitos milonitizados y ultra-milonitizados de edad grenviliana y lentes de mármol bandeado y de grano fino, cálcicos y dolomíticos. El conjunto fue tradicionalmente incluido dentro de la Formación Río Bonete, separándose a los mármoles como Miembro Caliza Las Damas. La Formación Río Bonete incluía, además, una sucesión de areniscas y pelitas con arreglo rítmico y afectado por muy bajo grado metamórfico de edad ordovícica superior. De acuerdo a un nuevo mapeo, se trataría de dos unidades distintas separadas por discordancia, considerando conveniente utilizar el término Complejo Metamórfico Río Bonete para la unidad con deformación dúctil y Formación Chuscho para las metasedimentitas interdigitadas con vulcanitas básicas incluidas en la faja ofiolítica famatiniana. Por su parte, y para evitar confusiones, se propone reemplazar el término Miembro Calizas Las Damas por el de Mármol Las Damas que refleja mejor su composición. Considerando que la Formación Chuscho, a pesar de su muy bajo grado de metamorfismo, no ha sido involucrada en la deformación dúctil y que los mármoles por su bandeado composicional se correlacionarían con unidades cámbricas de la plataforma del terreno de Precordillera, la edad de la faja quedaría acotada al Paleozoico inferior, consistente con la orogenia oclóyica.

Se trata de una secuencia de bancos rojos de unos 122 m de espesor compuesta por areniscas, pelitas, margas y delgados niveles de evaporitas. Estas rocas fueron divididas en seis asociaciones de facies, las que caracterizan en su mayor parte a un sistema lacustre desarrollado bajo condiciones áridas o semiáridas. Probablemente como resultado de un incremento en la aridez, los sedimentos lacustres fueron reemplazados por condiciones de sedimentación eólica bien representadas en el techo de la unidad. La secuencia lacustre muestra al menos dos ciclos de expansión-contracción, el primero es el de mayor desarrollo, dominado durante el estado de máxima inundación por niveles de pelitas negras fosilíferas. Estos últimos han provisto microfósiles calcáreos, palinomorfos y restos de gastrópodos en regular estado de preservación. Los microfósiles calcáreos incluyen charophytas y ostrácodos.

    2016-05-01

    Palaeomagnetic data from poorly consolidated to non-consolidated late Cenozoic sediments along the central segment of the active El Tigre Fault (Central-Western Precordillera of the San Juan Province, Argentina) demonstrate broad cumulative deformation up to ~450 m from the fault trace and reveal clockwise and anticlockwise vertical-axis rotations of variable magnitude. This deformation has affected in different amounts Miocene to late Pleistocene samples and indicates a complex kinematic pattern. Several inherited linear structures in the shear zone that are oblique to the El Tigre Fault may have acted as block boundary faults. Displacement along these faults may have resulted in a complex pattern of rotations. The maximum magnitude of rotation is a function of the age of the sediments sampled, with largest values corresponding to middle Miocene-lower Pliocene deposits and minimum values obtained from late Pleistocene deposits. The kinematic study is complemented by low-field anisotropy of magnetic susceptibility data to show that the local strain regime suggests a N-S stretching direction, subparallel to the strike of the main fault.

    Full Text Available En las quebradas de Santa Elena y del Telégrafo, Uspallata, Precordillera mendocina, fueron descriptas rocas volcánicas de edad permotriásica, asignadas al Grupo Choiyoi. En este sector el grupo está representado por una secuencia volcánica, formada a partir de varios eventos piroclásticos de diferente magnitud, sucedidos en intervalos de tiempos cortos. Se reconocieron ochos eventos volcánicos, integrados por litofacies tales como flujos ignimbríticos parcialmente soldados, flujos ignimbríticos densamente soldados, vitrófiros y perlitas, oleadas piroclásticas y depósitos de caídas de tefras y cenizas. La composición determinada a través de observaciones petrográficas revela una acidificación creciente hacia las litofacies superiores, variando gradualmente de fenodacitas a riofenodacitas, finalizando con fenoriolitas. El esquema geológico definido para el área de estudio permite correlacionar dichas unidades con la Formación Horcajo, descripta para el valle del río de los Patos en la provincia de San Juan. Los espesores medidos disminuyen notablemente hacia el NNO y el SSE, lo que sugiere que los flujos se movilizaron canalizados en dirección NE-SO.

El inicio de un ascenso relativo del nivel del mar aparece registrado en la asociación de facies 2, formada por areniscas y pelitas carbonosas depositadas en ambientes transicionales, probablemente estuarinos. La asociación de facies 3, compuesta por areniscas finas, indica el pasaje a un ambiente marino costero, mientras que la asociación de facies 4 incluye areniscas con paquetes de estratificación entrecruzada de gran escala y probablemente corresponde a ambientes subtidales con importante crecimiento de barras de arena de gran porte. Una progresiva somerización llevó a la depositación de pelitas carbonosas, areniscas finas e intercalaciones de margas (asociación de facies 5 en ambientes restringidos (albuferas.

El pavimento está cubierto por pelitas con clastos caídos y diamictitas en bancos delgados (cortejo transgresivo inicial, seguidas por fangolitas con fósiles (cortejo transgresivo final. La secuencia II se inicia con areniscas gruesas y conglomerados que apoyan en discordancia erosiva sobre fangolitas y areniscas finas de la secuencia I. Este marcado cambio indica un drástico traslado de facies hacia el centro de la cuenca, coincidente con los contactos entre a las Formaciones Hoyada Verde (y su equivalente Formación El Paso y Tres Saltos, y b los Miembros Diamictítico y Rojo I de la Formación Majaditas.

    Full Text Available La Precordillera Sur y las Cerrilladas Pedemontanas de Mendoza, son dos unidades morfotectónicas principales en la vertiente oriental de los Andes centrales, a los 31º30' - 33º30' de latitud sur. Allí, dos cinturones de deformación transpresiva y orientación noroeste, denominados fajas Barreal-Las Peñas y Río Mendoza-Tupungato, se desarrollaron como consecuencia de la gradual somerización de la placa de Nazca en los últimos 20 Ma. Su orientación y compleja geometría estructural resulta de la interferencia de la deformación andina tardío-cenozoica con la estructura de orientación noroeste del rift triásico de la cuenca Cuyana y antiguas zonas de sutura colisional de edad paleozoica. Este trabajo demuestra que los rasgos paleotectónicos del substrato triásico-paleozoico de la Precordillera Sur y del margen oriental de la Cordillera Frontal controlan la configuración morfotectónica y la distribución y reactivación de gran parte de la estructura neotectónica del margen andino a estas latitudes.

    Full Text Available En la quebrada del río Acequión, ubicada en el sur de la provincia de San Juan y norte de Mendoza (32º 10' S, en el centrooeste argentino, se efectuó el análisis de las fallas que afectan depósitos lacustres de edad holocena. Estas fallas se encuentran asociadas a estructuras de licuefacción y avalanchas de roca indicadoras de paleoterremotos, lo que permite extender el registro sísmico de la región hasta el Holoceno temprano. Al comparar el campo de esfuerzos regional actual (determinado por sismicidad instrumental, con el cálculo del mecanismo focal de los terremotos recientes ocurridos en la región con el campo de esfuerzos local, se observó que mientras el primero se caracteriza por la compresión, el campo local de la secuencia lacustre es extensional. Esto indicaría que aunque el esfuerzo regional actual es compresivo y de dirección NE-SO debido a la convergencia entre las placas de Nazca y Sudamérica, el antiguo lago adosado a las sierras de Pedernal y Los Pozos, está afectado por fallas normales, principalmente debido a esfuerzos locales distensivos originados por el reacomodamiento de estos depósitos durante el levantamiento de las zonas montañosas aledañas.An analysis of faults affecting Late Neogene lacustrine deposits was made in Acequión area, placed in the south of the province of San Juan. These faults are associated with liquefaction structures and rock avalanche deposits originated by paleoearthquakes, extending the earthquake records until the early Holocene in this region. By comparing the present regional stress field (determined by instrumental seismicity, with the focal mechanism analysis of recent earthquakes occurred in the region with the local stress field, it was observed that whereas the first one is characterized by compression, the local field on the lacustrine sequence is normal. The current regional stress field is compressive due to the subduction of Nazca plate under South America plate. The

    Full Text Available En este trabajo se da a conocer el hallazgo de sedimentitas maastrichtianas en la Precordillera septentrional (provincia de La Rioja. Se trata de una secuencia de bancos rojos de unos 122 m de espesor compuesta por areniscas, pelitas, margas y delgados niveles de evaporitas. Estas rocas fueron divididas en seis asociaciones de facies, las que caracterizan en su mayor parte a un sistema lacustre desarrollado bajo condiciones áridas o semiáridas. Probablemente como resultado de un incremento en la aridez, los sedimentos lacustres fueron reemplazados por condiciones de sedimentación eólica bien representadas en el techo de la unidad. La secuencia lacustre muestra al menos dos ciclos de expansión-contracción, el primero es el de mayor desarrollo, dominado durante el estado de máxima inundación por niveles de pelitas negras fosilíferas. Estos últimos han provisto microfósiles calcáreos, palinomorfos y restos de gastrópodos en regular estado de preservación. Los microfósiles calcáreos incluyen charophytas y ostrácodos. Entre las algas (girogonites se han identificado Platychara compressa y Tectochara sp. A. mientras que los ostrácodos están representados por Ilyocypris wichmanni punctata, Eucandona? sp., Cypridopsis sp. y Ovocytheridea? rionegrensis. Los palinomorfos aparecen como una asociación monoespecífica de colonias de algas del género Pediastrum. Las características litológicas, ubicación estratigráfica y el contenido fosilífero permiten correlacionar estos bancos rojos con los de la Formación Ciénaga del Río Huaco. La citada correlación amplía considerablemente la distribución regional de las sedimentitas cretácicas anteriormente limitadas a la Precordillera de San Juan.

    Full Text Available En el cordón del Peñasco, ubicado en el sector norte de la provincia de Mendoza, dentro del ámbito de la Precordillera Occidental, aforan metasedimentitas en contacto tectónico con una asociación máfica-ultramáfica. Dentro de las metasedimentitas en facies esquistos verdes se han reconocido dos asociaciones: metalimolitas carbonáticas y metaareniscas y metapelitas. Las rocas máficas-ultramáficas están representadas por serpentinitas derivadas de harzburgitas y dunitas, gabros bandeados metamorfizados en facies granulita; diabasas constituyendo diques o filones capa, metabasaltos amigdaloides y metahialoclastitas con bajo grado de metamorfismo. Se realizaron estimaciones termométricas en una granulita máfica (gabro bandeado utilizando el par granate-clinopiroxeno, obteniéndose temperaturas de 884°C. Las mismas permiten estimar que estos cuerpos experimentaron metamorfismo de alta temperatura, para posteriormente retrogradar a facies esquistos verdes, sobre la base de aspectos mineralógicos y texturales. Con respecto a las unidades metasedimentarias, el paleoambiente inferido para la unidad de metaareniscas y metapelitas corresponde a pie de talud continental con predominio de sedimentación gravitacional sobre la base de estructuras sedimentarias reconocidas. Mientras que la unidad de metalimolitas carbonáticas pertenecerían a un ambiente marino profundo. Estas unidades han sido asignadas al Eopaleozoico a partir de criterios estratigráficos y deformadas y metamorfizadas hacia fines del Devónico como consecuencia de la orogenia Chánica.

    Full Text Available La Formación Punta del Agua en el extremo noroccidental de la cuenca Paganzo, representa las primeras manifestaciones de actividad volcánica neopaleozoica en la Precordillera y en las Sierras Pampeanas. La variedad litológica de esta unidad comprende interestratificación de flujos lávicos, flujos piroclásticos y acumulaciones sedimentarias. Los flujos lávicos fueron divididos según su composición y textura; se incluyó en esta agrupación un filón capa de composición dacítica. Los flujos piroclásticos fueron subdivididos para su caracterización en depósitos gruesos de flujos de bloques y cenizas y reoignimbritas. Durante los períodos intereruptivos tuvo lugar la sedimentación de conglomerados volcánicos, arenitas líticas volcánicas y escasos niveles pelíticos; todas estas rocas conforman litosomas fuertemente lenticulares que reflejan la irregularidad morfológica del campo volcánico. Las características geoquímicas de las volcanitas fueron analizadas sobre la base de doce muestras provenientes de ambos flancos del sinclinal de Punta del Agua. Los valores obtenidos corresponden al espectro de rocas mesosilíceas y ácidas, desde andesitas basálticas hasta riolitas, aunque claramente dominan las composiciones andesíticas. El carácter calcoalcalino de estas rocas, y la abundancia relativa en K de las andesitas, sugieren líquidos padres originados en zonas de subducción con efectos de procesos de cristalización fraccionada y contaminación sobreimpuestos. En lo que corresponde a la antigüedad de la unidad ha sido establecida a partir de sus relaciones estratigráficas y dataciones radimétricas; ambas líneas de investigación sugieren una edad carbonífera superior para el conjunto, aunque sin descartar que sus términos cuspidales alcancen el Pérmico más temprano.

    Turbidity-current and storm-induced deposits may exhibit similarities, in particularly when the latter is laid down by a combination of oscillatory and unidirectional flows. Recent progress in facies analysis helps to discriminate the sedimentary effects of oscillatory from unidirectional components of the flow. On the basis of detailed analysis of sedimentary facies, strata geometry, and palaeocurrent data, the present study reinterprets the Punta Negra Formation (PNF) (Lower-Middle Devonian, Argentine Precordillera), previously considered as a depositional system of deep-water, as a storm-dominated prodeltaic shelf depositional system. In the sandstone beds of the PNF, planar, low-angle and undulating laminations with weakly asymmetric hummocky and swaley bedforms, combined-flow ripples, accretionary hummocky cross-stratification-like (HCS-like), and anisotropic HCS-like suggest the action of oscillatory currents combined with unidirectional currents in forming the deposits. Different hypotheses on the origin of the oscillatory currents have been examined. The most convincing interpretation is that the oscillatory component of the velocity is attributed to storm-induced waves. The palaeocurrent data indicate offshore current directions, suggesting that the unidirectional flow was a gravity-induced bottom current. Inverse grading at the base and overlying normally graded divisions of the sandstone beds testify to waxing-waning behaviour of the depositional flows; interbedding of sedimentary structures (undulating laminations, low-angle and parallel laminations, and combined-flow ripples) in the lower and intermediate divisions of the beds indicate fluctuations of flow velocity. This organisation of the sedimentary structures permits association of the unidirectional component with hyperpycnal bottom currents. The terrestrial origin of the hyperpycnal flows is suggested by the abundance of terrestrial plant remains, the mineralogical and textural immaturity of the

    Full Text Available Evidence of earthquake-induced liquefaction features in the Acequión river valley, central western Argentina, is analysed. Well-preserved soft-sediment deformation structures are present in Late Pleistocene deposits; they include two large slumps and several sand dikes, convolutions, pseudonodules, faults, dish structures and diapirs in the basal part of a shallow-lacustrine succession in the El Acequión River area. The water-saturated state of these sediments favoured deformation.

In this paper, the Cañón del Colorado Formation is characterized using five stratigraphic sections (P1, P2, P3, P4, P5 uniformly distributed along the outcrops. The P3 section, located in the middle of the outcrops, is defined as the type section because its integrity, and because it goes across the fossiliferous area as well. Three members were defined from the base to the top: lower, middle and upper members. Moreover, facies and facies association were defined, called: mudstone facies association (AFP, sandy-mudstone (AFPP, conglomerate-sandstone (AFCA and conglomerate. The sequence is characterized as an alluvial piedmont system integrated by fine grain sediments of playa -lake deposits (mudstone and sandy-mudstone facies association, rarely interlayered with the conglomerate without matrix facies association and distal to middle alluvial fan facies (Conglomerate-sandstone and conglomerate facies association. These facies form two progradant depositional sequences, the first one is integrated by the mudstone and the conglomerate facies association, while the second is integrated by the sandy-mudstone and the and the conglomerate-sandstone facies association, possibly linked to a passive border filling of a rift basin evolved along the "north Pie de Palo fault-alignment". Finally, using biostratigraphic correlation of the paleovertebrates located in middle member, a Lower Jurassic (Hettangian-Toarcian age is suggested for the Cañón del Colorado Formation.

    Full Text Available Se define en este trabajo a la Formación Cuesta del Viento, una nueva unidad litoestratigráfica vinculada a la orogenia andina en la Precordillera occidental. La unidad descansa en discordancia angular sobre sedimentitas de la Formación Puesto La Flecha (Oligoceno? o sobre metasedimentitas de la Formación Yerba Loca (Ordovícico, alcanzando un espesor de 520 m. Está mayormente formada por parabrechas monomícticas gris verdosas y en menor proporción por fangolitas castañas, areniscas y ortoconglomerados polimícticos. De acuerdo a dataciones radimétricas disponibles los términos cuspidales de la unidad alcanzaron el Mioceno inferior. El análisis sedimentológico del estratotipo, aflorante en el valle de La Tranca, permitió reconocer cinco asociaciones de facies. La asociación de facies 1 formada por brechas monomícticas masivas interpretadas como de abanicos coluviales dominados por flujos de gravedad. La asociación de facies 2 corresponde a brechas estratificadas en bancos lentiformes amalgamados, originadas en sistemas multicanalizados gravo-arenosos, de baja sinuosidad. La asociación de facies 3 está formada por areniscas y conglomerados polimícticos con clastos graníticos y volcánicos. Es posible que la composición de los clastos de esta última asociación de facies señale la transferencia de sedimentos, por sistemas fluviales entrelazados, desde la vecina cuenca ubicada al oeste de Rodeo-Iglesia. Las fangolitas y escasos conglomerados que forman la asociación de facies 4, han sido interpretados como originados en sistemas lacustres de baja profundidad con desarrollo de barras de desembocadura.

    Full Text Available The present review examines the main attributes and agronomic characteristics of arrowleaf clover (Trifolium vesiculosum Savi and its incorporation into production systems in dryland areas of the Andean foothills of the humid Mediterranean climate zone of Chile. It is a new species of annual legume in Chile for light and medium textured soils. The root system can reach a depth of 1.5 m and its seeds have a high percentage of hardseedness (99.8%. It is an upright plant, with purplish-white flowers. The mature plant has large arrow-shaped leaves up to 50 mm long, often marked with a large white “V”. Dry matter and seed production in the Andean foothills is high (3.9-8.8 t DM ha-1 and 700-900 kg ha-1, respectively, surpassing the productivity of sub clover (Trifolium subterraneum L. cv. Mount Barker and crimson clover (Trifolium incarnatum L.. However, DM production in the second year was lower, possibly because the high percentage of hardseedness inhibited plant emergence. The phenological records and productive performance suggest that arrowleaf clover could contribute to improving pastoral production in dryland areas with annual rainfall levels of more than 800 mm, such as the Andean foothills in the central-southern region of Chile.En la presente revisión se examinan los principales atributos y características agronómicas del trébol vesiculoso (Trifolium vesiculosum Savi y su eventual incorporación a sistemas de producción en la precordillera andina de la zona de clima mediterráneo húmedo de Chile.

    This paper argues that drone filming can substantiate our understanding of multisensorial experiences of quiet areas and urban landscapes. Contrary to the distanced gaze often associated with the drone, this paper discusses drone filming as an intimate performativity apparatus that can affect...... perception as a result of its interrelationships between motion, gaze, and sound. This paper uses four films, one of which is a drone flyover, to launch a discussion concerning a smooth and alluring gaze, a sliding gaze that penetrates landscapes, and site appearance. Films hold the capacity to project both...... and transcendence can facilitate a deeper understanding of intimate sensations, substantiating their role in the future design and planning of urban landscapes. Hence, it addresses the ethics of an intimacy perspective (of drone filming) in the qualification of quiet areas....

    1984-01-01

    A geologic and mineral survey was conducted in the Pyramid Roadless Area, California. The area contains mineral showings, but no mineral-resource potential was identified during our studies. Three granodiorite samples on the west side of the roadless area contained weakly anomalous concentrations of uranium. Two samples of roof-pendant rocks, one metasedimentary rock and one metavolcanic rock, contain low concentrations of copper, and of copper and molybdenum, respectively. Although none was identified, the geologic terrane is permissive for mineral occurrences and large-scale, detailed geologic mapping of the areas of metasedimentary and metavolcanic roof pendants in the Pyramid Roadless Area could define a mineral-resource potential for tungsten and precious metals.

  3. Protected areas and poverty

    2015-01-01

    Protected areas are controversial because they are so important for conservation and because they distribute fortune and misfortune unevenly. The nature of that distribution, as well as the terrain of protected areas themselves, have been vigorously contested. In particular, the relationship between protected areas and poverty is a long-running debate in academic and policy circles. We review the origins of this debate and chart its key moments. We then outline the continuing flashpoints and ways in which further evaluation studies could improve the evidence base for policy-making and conservation practice. PMID:26460124

    In January 1994, the US Department of Energy Office of Environmental Management (DOE EM) formally introduced its new approach to managing DOE`s environmental research and technology development activities. The goal of the new approach is to conduct research and development in critical areas of interest to DOE, utilizing the best talent in the Department and in the national science community. To facilitate this solutions-oriented approach, the Office of Science and Technology (EM-50, formerly the Office of Technology Development) formed five Focus AReas to stimulate the required basic research, development, and demonstration efforts to seek new, innovative cleanup methods. In February 1995, EM-50 selected the DOE Morgantown Energy Technology Center (METC) to lead implementation of one of these Focus Areas: the Decontamination and Decommissioning (D & D) Focus Area.

    Solid state lighting using LED-dies is a rapidly growing market. LED-dies with the needed increasing luminous flux per chip area produce a lot of heat. Therefore an appropriate thermal management is required for general lighting with LEDdies. One way to avoid overheating and shorter lifetime is the use of many small LED-dies on a large area heat sink (down to 70 μm edge length), so that heat can spread into a large area while at the same time light also appears on a larger area. The handling with such small LED-dies is very difficult because they are too small to be picked with common equipment. Therefore a new concept called collective transfer bonding using a temporary carrier chip was developed. A further benefit of this new technology is the high precision assembly as well as the plane parallel assembly of the LED-dies which is necessary for wire bonding. It has been shown that hundred functional LED-dies were transferred and soldered at the same time. After the assembly a cost effective established PCB-technology was applied to produce a large-area light source consisting of many small LED-dies and electrically connected on a PCB-substrate. The top contacts of the LED-dies were realized by laminating an adhesive copper sheet followed by LDI structuring as known from PCB-via-technology. This assembly can be completed by adding converting and light forming optical elements. In summary two technologies based on standard SMD and PCB technology have been developed for panel level LED packaging up to 610x 457 mm2 area size.

    On the basis of mineral-resource surveys the Selkirk Roadless Area, Idaho has little promise for the occurrence of mineral or energy resources. Molybdenum, lead, uranium, thorium, chromium, tungsten, zirconium, and several rare-earth elements have been detected in panned concentrates from samples of stream sediment, but no minerals containing the first five elements were found in place, nor were any conditions conducive to their concentration found. Zirconium, thorium, and the rare earths occur in sparsely disseminated accessory minerals in granitic rocks and no resource potential is identified. There is no history of mining in the roadless area and there are no oil, gas, mineral, or geothermal leases or current claims.

    To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this new approach, EM developed a management structure and principles that led to the creation of specific Focus Areas. These organizations were designed to focus the scientific and technical talent throughout DOE and the national scientific community on the major environmental restoration and waste management problems facing DOE. The Focus Area approach provides the framework for intersite cooperation and leveraging of resources on common problems. After the original establishment of five major Focus Areas within the Office of Technology Development (EM-50, now called the Office of Science and Technology), the Nuclear Materials Stabilization Task Group (EM-66) followed the structure already in place in EM-50 and chartered the Plutonium Focus Area (PFA). The following information outlines the scope and mission of the EM, EM-60, and EM-66 organizations as related to the PFA organizational structure.

    The US Department of Enregy (DOE) Subsurface Contaminants Focus Area is developing technologies to address environmental problems associated with hazardous and radioactive contaminants in soil and groundwater that exist throughout the DOE complex, including radionuclides, heavy metals; and dense non-aqueous phase liquids (DNAPLs). More than 5,700 known DOE groundwater plumes have contaminated over 600 billion gallons of water and 200 million cubic meters of soil. Migration of these plumes threatens local and regional water sources, and in some cases has already adversely impacted off-site rsources. In addition, the Subsurface Contaminants Focus Area is responsible for supplying technologies for the remediation of numerous landfills at DOE facilities. These landfills are estimated to contain over 3 million cubic meters of radioactive and hazardous buried Technology developed within this specialty area will provide efective methods to contain contaminant plumes and new or alternative technologies for development of in situ technologies to minimize waste disposal costs and potential worker exposure by treating plumes in place. While addressing contaminant plumes emanating from DOE landfills, the Subsurface Contaminants Focus Area is also working to develop new or alternative technologies for the in situ stabilization, and nonintrusive characterization of these disposal sites.

    Tiina Maria Ikäheimo

    2011-10-01

    Full Text Available Circumpolar areas are associated with prolonged cold exposure where wind, precipitation, and darkness further aggravate the environmental conditions and the associated risks. Despite the climate warming, cold climatic conditions will prevail in circumpolar areas and contribute to adverse health effects. Frostbite is a freezing injury where localized damage affects the skin and other tissues. It occurs during occupational or leisure-time activities and is common in the general population among men and women of various ages. Industries of the circumpolar areas where frostbite occurs frequently include transportation, mining, oil, and gas industry, construction, agriculture, and military operations. Cold injuries may also occur during leisure-time activities involving substantial cold exposure, such as mountaineering, skiing, and snowmobiling. Accidental situations (occupational, leisure time often contribute to adverse cooling and cold injuries. Several environmental (temperature, wind, wetness, cold objects, and altitude and individual (behavior, health, and physiology predisposing factors are connected with frostbite injuries. Vulnerable populations include those having a chronic disease (cardiovascular, diabetes, and depression, children and the elderly, or homeless people. Frostbite results in sequelae causing different types of discomfort and functional limitations that may persist for years. A frostbite injury is preventable, and hence, unacceptable from a public health perspective. Appropriate cold risk management includes awareness of the adverse effects of cold, individual adjustment of cold exposure and clothing, or in occupational context different organizational and technical measures. In addition, vulnerable population groups need customized information and care for proper prevention of frostbites.

  10. Vehicular road influence areas

    Science.gov (United States)

    Huertas, María E.; Huertas, José I.; Valencia, Alexander

    2017-02-01

    Vehicle operation over paved and unpaved roads is an emission source that significantly contributes to air pollution. Emissions are derived from vehicle exhaust pipes and re-suspension of particulate matter generated by wind erosion and tire to road surface interactions. Environmental authorities require a methodology to evaluate road impact areas, which enable managers to initiate counter-measures, particularly under circumstances where historic meteorological and/or air quality data is unavailable. The present study describes an analytical and experimental work developed to establish a simplified methodology to estimate the area influenced by vehicular roads. AERMOD was chosen to model pollutant dispersion generated by two roads of common attributes (straight road over flat terrain) under the effects of several arbitrary chosen weather conditions. The resulting pollutant concentration vs. Distance curves collapsed into a single curve when concentration and distance were expressed as dimensionless numbers and this curve can be described by a beta distribution function. This result implied that average concentration at a given distance was proportional to emission intensity and that it showed minor sensitivity to meteorological conditions. Therefore, road influence was defined by the area adjacent to the road limited by distance at which the beta distribution function equaled the limiting value specified by the national air quality standard for the pollutant under consideration.

    Zafiropoulo, P

    1982-01-01

    Pitro Zafiropulo is a- staff member at the IBM Research Laboratories at Zurich. He joined IBM in 1968 and has worked on protocol validation, synthesis, integrated networks, network reliability, PABX's and speech recognition. Local Area Networks are intended to provide improved communication capabilities such as high data throughput rates, low error rates and ease of connection among terminal stations and comuters. These new types of networks operate within a limited geographical range like an establishment, campus or building and are owned by a single organization. The presentation introduces these networks and the main techniques are described. It then proceeds to evaluate the main switching techniques as they apply to LAN ring and bus configurations. The preferred technique of token-ring distributed switching is identified. The contents of Mr. Zafiropoulo's talk was somewhat similar to the paper of Mr. Kummerle, which is therefore included in these Proceedings.

    Full Text Available En la depresión situada entre los ríos de La Flecha y del Agua, se encuentran evidencias de fallamiento cuaternario, entre dos sistemas estructurales con rumbo norte y vergencias opuestas, Precordillera Central con vergencia oriental y estilo de piel fina y Precordillera Oriental, con vergencia occidental y piel gruesa. Se reconocieron numerosas fallas con actividad cuaternaria a lo largo de toda la depresión: aquellas ubicadas en su porción oriental, en las proximidades del cerro La Chilca, con el mismo estilo estructural de Precordillera Oriental: fallas inversas inclinando al este con alto ángulo en la superficie. Por el contrario, las fallas localizadas en el piedemonte oriental del cordón de Las Osamentas tienen un estilo estructural consistente con Precordillera Central, inversas y con vergencia oriental. Este arreglo estructural de las fallas cuaternarias con vergencia opuesta se compara con aquellos descriptos en la depresión de Matagusanos, donde se identificó una zona triangular de tipo piel gruesa localizada cerca de su porción occidental y en el valle de zonda, situado al norte del sector analizado.Evidence of Quaternary faults between two structural systems with regional N-trending strike and opposite vergence occur at the depression located between La Flecha and del Agua rivers; the east-verging thin-skinned Central Precordillera and the west-verging, thick-skinned Eastern Precordillera. Several Quaternary faults have been recognized across the whole depression. Those located in the eastern sector near Cerro La Chilca, show the structural style of Precordillera Oriental: east-dipping reverse faults with a high angle on the surface. On the contrary, faults located at the eastern piedmont of Cordón de Las Osamentas have a structural style consistent with Precordillera Central, reverse faults and east vergence. This structural arrange of Quaternary faults with opposite vergence was compared with those described at

    Full Text Available Croatia has been seeking to achive pre-war results in tourism since its independence. Rural tourism in Croatia based on family farma faces a number of problems legal foundations, the involement of local communities, inadequate entepreneur support etc. The political will for development exists, but there is lack of willingness and the ability to get things started, which results in the closure of family farma who cannot cope with the parallel job of agriculture and tourism. Arriving guests certainly want a new type of tourism: peace, clean environment, cultural intangible and tangible treasures, all without the noise and stress; and Croatia can definitely offer it, either in coastal or inland areas with traditional food and drinks. The destinations connection is not satisfactora. there is also an evident lack of legislation and regional spatial development plans for sustainable tourism which is a prerequisite for successful tourism. With these plans presumptins accepted, Croatian tourism would become distinctive and inland and coastal branches of tourism could complement each other so that the customer can spend his vacation both in the continental ant the maritime part of the country, getting to know our culture and enjoy the traditional cousine.

  20. Global protected area impacts.

    Science.gov (United States)

    Joppa, Lucas N; Pfaff, Alexander

    2011-06-01

    Protected areas (PAs) dominate conservation efforts. They will probably play a role in future climate policies too, as global payments may reward local reductions of loss of natural land cover. We estimate the impact of PAs on natural land cover within each of 147 countries by comparing outcomes inside PAs with outcomes outside. We use 'matching' (or 'apples to apples') for land characteristics to control for the fact that PAs very often are non-randomly distributed across their national landscapes. Protection tends towards land that, if unprotected, is less likely than average to be cleared. For 75 per cent of countries, we find protection does reduce conversion of natural land cover. However, for approximately 80 per cent of countries, our global results also confirm (following smaller-scale studies) that controlling for land characteristics reduces estimated impact by half or more. This shows the importance of controlling for at least a few key land characteristics. Further, we show that impacts vary considerably within a country (i.e. across a landscape): protection achieves less on lands far from roads, far from cities and on steeper slopes. Thus, while planners are, of course, constrained by other conservation priorities and costs, they could target higher impacts to earn more global payments for reduced deforestation.

    In the planning of public transport catchment areas of stops are often included to estimate potential number of travellers. There are different approaches to GIS-based catchment area analyses depending on the desired level of detail. The Circular Buffer approach is the fundamental, but also...... the simplest approach. The Service Area approach is based on searches in road networks and represents the actual feeder routes and is thereby a more detailed approach. The Service Area approach can be refined by adding additional resistance to certain points in the road network, e.g. stairways. Differences...... between the Circular Buffer approach and the Service Area approach are illustrated and a comparison between the sizes of the catchment areas is made. The strength of the Service Area approach and the impact on the catchment area when adding additional time resistance to crossing of stairways...

  12. STRAWBERRY CRATER ROADLESS AREAS, ARIZONA.

    Science.gov (United States)

    Wolfe, Edward W.; Light, Thomas D.

    1984-01-01

    The results of a mineral survey conducted in the Strawberry Crater Roadless Areas, Arizona, indicate little promise for the occurrence of metallic mineral or fossil fuel resources in the area. The area contains deposits of cinder, useful for the production of aggregate block, and for deposits of decorative stone; however, similar deposits occur in great abundance throughout the San Francisco volcanic field outside the roadless areas. There is a possibility that the Strawberry Crater Roadless Areas may overlie part of a crustal magma chamber or still warm pluton related to the San Francisco Mountain stratovolcano or to basaltic vents of late Pleistocene or Holocene age. Such a magma chamber or pluton beneath the Strawberry Crater Roadless Areas might be an energy source from which a hot-, dry-rock geothermal energy system could be developed, and a probable geothermal resource potential is therefore assigned to these areas. 9 refs.

    1981-01-01

    Geothermal Resource area 9 encompasses all of Nye County, Nevada. Within this area there are many different known geothermal sites ranging in temperature from 70/sup 0/ to over 265/sup 0/ F. Fifteen of the more major sites have been selected for evaluation in this Area Development Plan. Various potential uses of the energy found at each of the resource sites discussed in this Area Development Plan were determined after evaluating the area's physical characteristics, land ownership and land use patterns, existing population and projected growth rates, and transportation facilities, and comparing those with the site specific resource characteristics. The uses considered were divided into five main categories: electrical generation, space heating, recreation, industrial process heat, and agriculture. Within two of these categories certain subdivisions were considered separately. The findings about each of the 15 geothermal sites considered in this Area Development Plan are summarized.

    Muffler, L.J. Patrick; Campbell, Harry W.

    1984-01-01

    Geologic and mineral-resource investigations identified no mineral-resource potential in the Lost Creek Roadless Area, California. Sand and gravel have been mined from alluvial flood-plain deposits less than 1 mi outside the roadless area; these deposits are likely to extend into the roadless area beneath a Holocene basalt flow that may be as much as 40 ft thick. An oil and gas lease application which includes the eastern portion of the roadless area is pending. Abundant basalt in the area can be crushed and used as aggregate, but similar deposits of volcanic cinders or sand and gravel in more favorable locations are available outside the roadless area closer to major markets. No indication of coal or geothermal energy resources was identified.

    2003-01-01

    This study has identified the active cerebral areas of normal Chinese that are associated with Chinese semantic processing using functional brain imaging. According to the traditional cognitive theory, semantic processing is not particularly associated with or affected by input modality. The functional brain imaging experiments were conducted to identify the common active areas of two modalities when subjects perform Chinese semantic tasks through reading and listening respectively. The result has shown that the common active areas include left inferior frontal gyrus (BA 44/45), left posterior inferior temporal gyrus (BA37); the joint area of inferior parietal lobules (BA40) and superior temporal gyrus, the ventral occipital areas and cerebella of both hemispheres. It gives important clue to further discerning the roles of different cerebral areas in Chinese semantic processing.

    2013-12-01

    Full Text Available This study aimed to estimate the watershed runoff caused by extreme events that often result in the flooding of urban areas. The runoff of a residential area in the city of Guaratinguetá, São Paulo, Brazil was estimated using the Curve-Number method proposed by USDA-NRCS. The study also investigated current land use and land cover conditions, impermeable areas with pasture and indications of the reforestation of those areas. Maps and satellite images of Residential Riverside I Neighborhood were used to characterize the area. In addition to characterizing land use and land cover, the definition of the soil type infiltration capacity, the maximum local rainfall, and the type and quality of the drainage system were also investigated. The study showed that this neighborhood, developed in 1974, has an area of 792,700 m², a population of 1361 inhabitants, and a sloping area covered with degraded pasture (Guaratinguetá-Piagui Peak located in front of the residential area. The residential area is located in a flat area near the Paraiba do Sul River, and has a poor drainage system with concrete pipes, mostly 0.60 m in diameter, with several openings that capture water and sediments from the adjacent sloping area. The Low Impact Development (LID system appears to be a viable solution for this neighborhood drainage system. It can be concluded that the drainage system of the Guaratinguetá Riverside I Neighborhood has all of the conditions and characteristics that make it suitable for the implementation of a low impact urban drainage system. Reforestation of Guaratinguetá-Piagui Peak can reduce the basin’s runoff by 50% and minimize flooding problems in the Beira Rio neighborhood.

    This report documents the history of the major buildings in Sandia National Laboratories` Technical Area II. It was prepared in support of the Department of Energy`s compliance with Section 106 of the National Historic Preservation Act. Technical Area II was designed and constructed in 1948 specifically for the final assembly of the non-nuclear components of nuclear weapons, and was the primary site conducting such assembly until 1952. Both the architecture and location of the oldest buildings in the area reflect their original purpose. Assembly activities continued in Area II from 1952 to 1957, but the major responsibility for this work shifted to other sites in the Atomic Energy Commission`s integrated contractor complex. Gradually, additional buildings were constructed and the original buildings were modified. After 1960, the Area`s primary purpose was the research and testing of high-explosive components for nuclear weapons. In 1994, Sandia constructed new facilities for work on high-explosive components outside of the original Area II diamond-shaped parcel. Most of the buildings in the area are vacant and Sandia has no plans to use them. They are proposed for decontamination and demolition as funding becomes available.

    When oil companies are entering new unexplored areas their potential footprint on the environment should be measured in a way that necessary action could be included in the planning of the activity. These actions should reduce the impact to accepted levels. Traditional baseline studies, including sediment and macro fauna sampling, are carried out in homogeneous areas. In heterogeneous and unexplored areas there is a need for more information than these traditional sediment analyses can give. To increase the knowledge from specific areas biodiversity mapping has been carried out. To combine the knowledge from ROV surveys, modelling, current measurements, sediment characteristics, seismic, macro fauna and background levels of chemicals contents in the sediments, both prior to the exploration, and after the drilling have taken place the operator can document their footprint on the marine environment.

Much of the roadless area has probable and substantiated potential for resources of gold, silver, molybdenum, and tungsten. The nature of the geologic terrain indicates that there is little promise for the occurrence of coal, oil, gas, or geothermal resources. Detailed geologic and geochemical studies are suggested to delineate exploration targets that could be tested by drilling.

  10. Geothermal resource area 3: Elko County. Area development plan

    Pugsley, M.

    1981-01-01

    Geothermal Resource Area 3 includes all of the land in Elko County, Nevada. There are in excess of 50 known thermal anomalies in this area. Several of the more major resources have been selected for detailed description and evaluation in this Area Development Plan. The other resources are considered too small, too low in temperature, or too remote to be considered for development in the near future. Various potential uses of the energy found at each of the studied resource sites in Elko County were determined after evaluating the area's physical characteristics; the land ownership and land use patterns; existing population and projected growth rates; transportation facilities and energy requirements. These factors were then compared with resource site specific data to determine the most likely uses of the resource. The uses considered in this evaluation were divided into five main categories: electrical generation, space heating, recreation, industrial process heat, and agriculture. Within two of these categories several subdivisions were considered separately. It was determined that several of the geothermal resources evaluated in the Area Development Plan could be commercially developed. The potential for development for the seven sites considered in this study is summarized.

  13. Suburban areas and urban life

    DEFF Research Database (Denmark)

    Melgaard, Bente

    Danish suburbs are facing major challenges trying to coping with demographic changes, with structural changes in retail businesses and especially with sustainability-related challenges that have to do with cutting back on energy consumption for heating and transportation. Also climate changes...... and counteracting the segregation of the suburbs into sharply socially-separated residential areas are major challenges. Therefore, in these years the post-war era’s suburban areas are being revitalized and the suburb urban life and urban qualities are concepts, which are often brought up in this context....... In this paper I will explore the concepts “suburb” and “urban life”. More than half of the Danish population live in suburban areas, and the majority of suburbs were built in a short and hectic period in the years from 1960 to 1975 and in conformity with the functionalist ideals that gave rise to a number...

    1996-03-01

    To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this approach, EM developed a management structure and principles that led to creation of specific focus areas. These organizations were designed to focus scientific and technical talent throughout DOE and the national scientific community on major environmental restoration and waste management problems facing DOE. The focus area approach provides the framework for inter-site cooperation and leveraging of resources on common problems. After the original establishment of five major focus areas within the Office of Technology Development (EM-50), the Nuclear Materials Stabilization Task Group (NMSTG, EM-66) followed EM-50`s structure and chartered the Plutonium Focus Area (PFA). NMSTG`s charter to the PFA, described in detail later in this book, plays a major role in meeting the EM-66 commitments to the Defense Nuclear Facilities Safety Board (DNFSB). The PFA is a new program for FY96 and as such, the primary focus of revision 0 of this Technology Summary is an introduction to the Focus Area; its history, development, and management structure, including summaries of selected technologies being developed. Revision 1 to the Plutonium Focus Area Technology Summary is slated to include details on all technologies being developed, and is currently planned for release in August 1996. The following report outlines the scope and mission of the Office of Environmental Management, EM-60, and EM-66 organizations as related to the PFA organizational structure.

    Full Text Available En la quebrada del río Acequión, ubicada en el sur de la provincia de San Juan y norte de Mendoza (32º 10' S, en el centrooeste argentino, se efectuó el análisis de las fallas que afectan depósitos lacustres de edad holocena. Estas fallas se encuentran asociadas a estructuras de licuefacción y avalanchas de roca indicadoras de paleoterremotos, lo que permite extender el registro sísmico de la región hasta el Holoceno temprano. Al comparar el campo de esfuerzos regional actual (determinado por sismicidad instrumental, con el cálculo del mecanismo focal de los terremotos recientes ocurridos en la región con el campo de esfuerzos local, se observó que mientras el primero se caracteriza por la compresión, el campo local de la secuencia lacustre es extensional. Esto indicaría que aunque el esfuerzo regional actual es compresivo y de dirección NE-SO debido a la convergencia entre las placas de Nazca y Sudamérica, el antiguo lago adosado a las sierras de Pedernal y Los Pozos, está afectado por fallas normales, principalmente debido a esfuerzos locales distensivos originados por el reacomodamiento de estos depósitos durante el levantamiento de las zonas montañosas aledañas.

    Full Text Available The simulation of current and projected wildfires is essential for predicting crucial aspects of vegetation patterns, biogeochemical cycling as well as pyrogenic emissions across the African continent. This study uses a data-driven approach to parameterize two burned area models applicable to dynamic vegetation models (DVMs and Earth system models (ESMs. We restricted our analysis to variables for which either projections based on climate scenarios are available, or that are calculated by DVMs, and we consider a spatial scale of one degree as the scale typical for DVMs and ESMs. By using the African continent here as an example, an analogue approach could in principle be adopted for other regions, for global scale dynamic burned area modelling.

    We used 9 years of data (2000–2008 for the variables: precipitation over the last dry season, the last wet season and averaged over the last 2 years, a fire-danger index (the Nesterov index, population density, and annual proportion of area burned derived from the MODIS MCD45A1 product. Two further variables, tree and herb cover were only available for 2001 as a remote sensing product. Since the effect of fires on vegetation depends strongly on burning conditions, the timing of wildfires is of high interest too, and we were able to relate the seasonal occurrence of wildfires to the daily Nesterov index.

    We parameterized two generalized linear models (GLMs, one with the full variable set (model VC and one considering only climate variables (model C. All introduced variables resulted in an increase in model performance. Model VC correctly predicts the spatial distribution and extent of fire prone areas though the total variability is underrepresented. Model VC has a much lower performance in both aspects (correlation coefficient of predicted and observed ratio of burned area: 0.71 for model VC and 0.58 for model C. We expect the remaining variability to be attributed to additional

    1984-01-01

    The Agua Tibia Primitive Area in southwestern California is underlain by igneous and metamorphic rocks that are siilar to those widely exposed throughout much of the Peninsular Ranges. To detect the presence of any concealed mineral deposits, samples of stream sediments were collected along the various creeks that head in the mountain. As an additional aid in evaluating the mineral potential, an aeromagnetic survey was made and interpreted. A search for records of past or existing mining claims within the primitive area was made but none was found. Evidence of deposits of metallic or nonmetallic minerals was not seen during the study.

    Geologic, geochemical, and geophysical studies together with a review of historic mining and prospecting activities indicate that the Cactus Spring Roadless Area in California has little promise for the occurrence of mineral or energy resources. Marble bodies occur in the northern part of the roadless area and are possible resources for building stone, crushed and quarried aggregate, and lime and magnesium for Portland cement and industrial applications. It is recommended that the terrane of marble be mapped and sampled carefully in order to evaluate the quantity and quality of the carbonate resources.

    The boundary for the Wyoming Basins Ecoregional Assessment (WBEA) was largely determined by the co-occurrence of some of the largest tracts of intact sagebrush (Artemisia spp.) remaining in the western United States with areas of increasing resource extraction. The WBEA area includes two ecoregions in their entirety, Wyoming Basins and Utah-Wyoming Rocky Mountains, and portions of two others (Southern Rocky Mountains and Middle Rockies-Blue Mountains). Over half the study area is in Wyoming; the remainder includes parts of Colorado, Utah, Idaho, and Montana. Private landowners manage most (33.1%) of the land base in the WBEA, followed by the U.S. Forest Service (27.3%) and U.S. Bureau of Land Management (25.6%). Sagebrush is the dominant land cover type in the study area, totaling >130,000 km2 ; nearly half the sagebrush in the WBEA is managed by the U.S. Bureau of Land Management. Sagebrush in the WBEA faces many potential threats that also influence the broader sagebrush ecosystem. Climate change, drought, land-use practices (e.g., livestock grazing, oil and gas development), and human development have eliminated and fragmented the sagebrush ecosystem, altered fire regimes, and accelerated the invasion of exotic plants such as cheatgrass (Bromus tectorum). Less than 2% of sagebrush in the WBEA is permanently protected from land cover conversion.

    2017-06-01

    Full Text Available The present article is a position paper aiming to initiate a professional debate related to the aspects related to the urban dysfunctions leading to the wear of the residential areas. The paper proposes a definition of the wear process, identify the main causes leading to its occurrence and propose a number of solutions to neutralise the dysfunctions. The three wearing phases of residential areas components are emphasized, exploring their lifecycle. In order to perform the study of urban wear, the status of the residential areas components can be established and monitored, and also the variables of the function that can mathematically model the specific wear process may be considered. The paper is considered a first step for the model adjustment, to be tested and validated in the following steps. Based on the mathematical method and model, there can be created, in a potential future research, the possibility of determining the precarity degree for residential areas/neighbourhoods and cities, by minimising the subjective component of the analyses preceding the decision for renovation or regeneration.

    Fenga, Concettina; Pugliese, Michela

    2013-01-01

    The Mediterranean is historically considered an area of high concentration of zoonoses. Mediterranean countries socio-economic features have favoured, over time, the onset of different types of zoonosis. Many of these may affect many occupational categories, first of all farmers, people working in abattoirs and processing products of animal origin. New farming activities and technologies have generated new occupational and zoonotic risks. These changes have influenced zoonosis epidemiology and have led to a gradual decrease in the number of diseases and to a reduction of some biological risks. However, brucellosis, Q fever, bovine tuberculosis cystic echinococcosis remain a strong example of zoonosis and a real risk, in the Mediterranean area especially. Therefore, an interdisciplinary collaboration between Veterinary Service, Public Health and Occupational medicine is necessary in order to plan territorial prevention.

    1984-01-01

    Mineral-resource surveys indicate that much of the Dolly Ann Roadless Area, in the George Washington National Forest, Alleghany County, Virginia, has substantiated iron resource potential. Inferred low-grade iron resources occur in folded sedimentary rocks of Paleozoic age. The area has an estimated 540 million long tons of contained iron in hematitic sandstone and 700,000 long tons contained iron in deposits of sandy Limonite. Other mineral resources include various rocks suitable for crushed rock, quartzite suitable for high-silica uses, limestone suitable for agricultural uses, and clay and shale suitable for structural clay products, all of which can be readily obtained outside the wilderness. A potential for natural gas and geothermal energy may exist but cannot be quantified from present knowledge.

    Dinaric Karst is one of the largest karst regions in Europe and in the World. It is the paramount karst of Europe and type site of many karst features. Dinaric Karst Area covers an extensive part of the Dinarides, a mountain chain in Southern Europe named after Dinara Mt., an impressive and outstanding rocky wall on the border between Dalmatian part of Croatia and Bosnia and Herzegovina. The Dinaric Karst occupies an area from the Friuli Plain (Doberdo Karst Plateau) and Slovenian mountains near Postojna cave on the northwest, to Skadar Lake and Prokletije Mt. on the southeast, from Central Bosnian Mountains on the northeast, and the Adriatic Sea seafloor with its islands. The Dinarides outspread in a so-called "Dinaric strike" (NW-SE) for 650 km in length and are up to 150 km wide across SW-NE. The biggest part of the Dinaric Karst Area is situated within Croatian territory (continental, Adriatic coastal and seafloor karst) comprising all karst features with exceptional examples exposed on the surface as well as in the underground. Classical karst area is the one situated in Slovenia, where typical karst features were described for the first time. Presentation of the outstanding values of Dinaric karst is based on the values that can be met in Italy, Bosnia and Herzegovina, Montenegro, Serbia and Albania, too. Dinaric Karst is the World's natural heritage because of its unique and outstanding geological characteristics and its living world; some of them are of outstanding natural beauty. Dinaric karst is an integral, compact karst area with extremely great thickness of carbonate rocks of predominantly Mesozoic age which in some areas exceeds 8.000 m. It bears several cycles of karstification thus giving world uniqueness to the area, especially regarding the wealth of submerged karst phenomena, among which vruljes are world unique features. Dinaric karst is one of the largest karst regions in the World. From the scientific perspective, the Dinaric Karst is one of

    Energy Technology Data Exchange (ETDEWEB)

    1994-03-01

    The mission of Environmental Management`s (EM) Office of Technology Development (OTD) Innovation Investment Area is to identify and provide development support for two types of technologies that are developed to characterize, treat and dispose of DOE waste, and to remediate contaminated sites. They are: technologies that show promise to address specific EM needs, but require proof-of-principle experimentation; and (2) already proven technologies in other fields that require critical path experimentation to demonstrate feasibility for adaptation to specific EM needs. The underlying strategy is to ensure that private industry, other Federal Agencies, universities, and DOE National Laboratories are major participants in developing and deploying new and emerging technologies. To this end, about 125 different new and emerging technologies are being developed through Innovation Investment Area`s (IIA) two program elements: RDDT&E New Initiatives (RD01) and Interagency Agreements (RD02). Both of these activities are intended to foster research and development partnerships so as to introduce innovative technologies into other OTD program elements for expedited evaluation.

    Kalirai, J. S.; Cox, C.; Dressel, L.; Fruchter, A.; Hack, W.; Kozhurina-Platais, V.; Mack, J.

    2010-04-01

    We present the pixel area maps (PAMs) for the WFC3/UVIS and WFC3/IR detectors, and discuss the normalization of these images. HST processed flt images suffer from geometric distortion and therefore have pixel areas that vary on the sky. The counts (electrons) measured for a source on these images depends on the position of the source on the detector, an effect that is implicitly corrected when these images are multidrizzled into drz files. The flt images can be multiplied by the PAMs to yield correct and uniform counts for a given source irrespective of its location on the image. To ensure consistency between the count rate measured for sources in drz images and near the center of flt images, we set the normalization of the PAMs to unity at a reference pixel near the center of the UVIS mosaic and IR detector, and set the SCALE in the IDCTAB equal to the square root of the area of this reference pixel. The implications of this choice for photometric measurements are discussed.

    Mr. Sandip R. Aher

    2014-08-01

    Full Text Available Performance evaluation of the Advanced Encryption Standard candidates has become led to intensive study of both hardware and software implementations. However, number of papers presents various implementation results, it shows that efficiency could still be greatly improved by applying effective design rules adapted to devices and algorithms. This paper shows various approaches for efficient FPGA implementations of the Advanced Encryption Standard algorithm. For different applications of the AES algorithm may require different s peed/area tradeoffs, we propose a vital study of the possible implementation schemes, but also the discussion of design methodology and algorithmic optimization in order to improve previous reported results. We propose system to evaluate hardware efficiency at different steps of the design process. We also use an optimal pipeline that takes the place and route constraints into account. Resulting circuits significantly improve the previous reported results: throughput has been up to 18.5 Gbits/sec and the area requirements can be limited to 542 slices and 10 RAM blocks with a ratio throughput/area improved by minimum 25% of the best-known designs in the Xilinx Virtex- E technology.

  6. RAINWATER MANAGEMENT IN PROTECTED AREAS

    Directory of Open Access Journals (Sweden)

    Wioletta Żarnowiec

    2017-03-01

    Full Text Available The aim of the study was to find out whether the climate of the southern Poland allows for removing rainwater from industrial areas by evaporation from roof surfaces. The study covered the premises of a Logistics Centre with an approximate area of 34 hectares, located in the catchment of the Wedonka stream and in the region of water intake for Kraków at the Rudawa river. In the future, the Centre will comprise nine large warehouses. Road traffic associated with the project will cause potential risks for groundwater and surface water of this protected area. Therefore, the Centre’s investor decided to evaporate rainwater from the premises. To establish advisability of this plan, the study team designed and built a unique experimental station consisting of experimental roof, tank for collecting water for the sprinkler system, system for delivering, distributing and discharging water from the roof, measuring tilt tray, automatic meteorological station, and electronic devices for recording measurement data. The research on the experimental station was carried out from April to October in 2011 and 2012 and included continuous measurements of the volume of water supplied to and discharged from the roof. Moreover, the temperature of the roof and water in the tank and a number of important meteorological parameters were measured. The difference between supplied and discharged water, divided by the wetted surface of the roof, helped to determine thickness of the evaporation layer in millimeters. The study confirmed the possibility of removing potentially contaminated rainwater by evaporating it from roof surfaces of the Logistics Centre located near Kraków at an average rate of 5.9 dm3·m–2.d–1. However, due to high seasonal variability of rainfall and air temperature, it is necessary to temporarily collect water in an expansion tank of suitable capacity.

    Rural transportation is facing the challenges of the required mobility increasing and the public transportation parallel being limited to a deficient level. A new mobility application (app) based on Intelligent Transport Systems (ITS), called Intelligent Carpooling, can be a significant contributor...... to mitigate these challenges. This system uses ITS to plan and coordinate carpooling. A study in two Danish rural areas found that a markedly part of residents are interesting in Intelligent Carpooling, but also that they require knowledge of whom they are driving with and as well as planning the carpooling...... carpooling work....

    Full Text Available Coasts were formed with the overall shape of earth's surface. Τhey represent a landform, as determined by the science of geomorphology. Being the boundary between land and sea, they present important features – particularities such as water currents, waves, winds, estuaries, drainage network, pollution etc. Coasts are examined at various levels: continents – oceans, states – large seas, as for example Mediterranean Sea. Greece, because of its horizontal and vertical partitioning, presents great extent and variety of coasts as mainland, peninsulas and islands. Depending on geomorphology, geology, soils, hydrology, land use of the inland and the coasts themselves, these are very diverse. Photogrammetry and Remote Sensing (defined by Statute II of ISPRS is the art, science, and technology of obtaining reliable information from non-contact imaging and other sensor systems about the Earth and its environment, and other physical objects and of processes through recording, measuring, analyzing and representation. This paper concerns critical considerations on the above. It also includes the case of Thessaloniki coasts in Greece, particularly river estuaries areas (river delta. The study of coastal areas of the wide surroundings of Thessaloniki city includes visual image interpretation – digital image processing techniques on satellite data of high spatial resolution.

  15. [Blood donation in urban areas].

    Science.gov (United States)

    Charpentier, F

    2013-05-01

    Medical and technical developments increase the difficulty to provide sufficient safe blood for all patients in developed countries and their sociodemographic and societal changes. Sufficient national blood supply remains a reached, however still actual, challenge. Tomorrow is prepared today: the management of blood donation programs both in line with these developments and with social marketing strategies is one of the keys to success. If the main components of this organization are well known (mobile blood drives in various appropriate environments, and permanent blood donation centers) their proportions in the whole process must evolve and their contents require adaptations, especially for whole blood donation in urban areas. We have to focus on the people's way of life changes related to increasing urbanization of the society and prominent position taken by very large cities. This requires targeting several goals: to draw the attention of the potential blood-giving candidate, to get into position to collect him when he will decide it, to give meaning and recognition to his "sacrifice" (give time rather than donate blood) and to give him desire and opportunity to come back and donate one more time. In this strategy, permanent blood centers in urban areas have significant potential for whole blood collection, highlighted by the decrease of apheresis technology requirements. This potential requires profound changes in their location, conception and organization. The concept of Maison Du Don (MDD) reflects these changes.

    Casini, Horacio; Lino, Eduardo Testé

    2014-01-01

    We discuss area terms in entanglement entropy and show that a recent formula by Rosenhaus and Smolkin is equivalent to the term involving a correlator of traces of the stress tensor in Adler-Zee formula for the renormalization of the Newton constant. We elaborate on how to fix the ambiguities in these formulas: Improving terms for the stress tensor of free fields, boundary terms in the modular Hamiltonian, and contact terms in the Euclidean correlation functions. We make computations for free fields and show how to apply these calculations to understand some results for interacting theories which have been studied in the literature. We also discuss an application to the F-theorem.

  17. Pythagorean triangles of equal areas

    1988-01-01

    Full Text Available The main intent in this paper is to find triples of Rational Pythagorean Triangles (abbr. RPT having equal areas. A new method of solving a2+ab+b2=c2 is to set a=y−1, b=y+1, y∈N−{0,1} and get Pell's equation c2−3y2=1. To solve a2−ab−b2=c2, we set a=12(y+1, b=y−1, y≥2, y∈N and get a corresponding Pell's equation. The infinite number of solutions in Pell's equation gives rise to an infinity of solutions to a2±ab+b2=c2. From this fact the following theorems are proved.

    Introduction A food allergy is a group of symptoms occurring in the organism and resulting from consuming some food, where the problems are conditioned by immunological mechanisms. The symptoms may become apparent first in adulthood and they may be an initial manifestation of a latent allergy. Typical symptoms of a food allergy occur in different organs, thus not only in the digestive system, but also in the skin, respiratory system and circulatory system. Aim To assess the frequency of food allergy onset in rural areas of the Lublin region as well as to determine which factors induce such allergies. Material and methods A survey was conducted, involving the participation of 340 inhabitants of rural areas. The study monitored the knowledge and situation of the disease, concerning allergens, allergy symptoms, methods of treatment and opinions regarding such treatment. Results The analysis focused on 124 people with diagnosed allergies. Conclusions Introducing a diet did not result in a statistically significant difference regarding elimination of the symptoms, as compared to the patients who did not follow any diet. On the other hand, pharmacological treatment causes statistically worse results than using other methods or not being treated at all. The patients in whom allergy symptoms disappeared were more convinced about the positive character of their diet than those in whom the symptoms were not eliminated. The age when the allergy becomes evident does not affect its duration, yet it matters as to the time of its later elimination. The more symptoms were experienced by a patient, the longer the duration of the allergy was. PMID:27605899

    The nev HB-Line, located on the fifth and sixth levels of Building 221-H, is designed to replace the aging existing HB-Line production facility. The nev HB-Line consists of three separate facilities: the Scrap Recovery Facility, the Neptunium Oxide Facility, and the Plutonium Oxide Facility. There are three separate safety analyses for the nev HB-Line, one for each of the three facilities. These are issued as supplements to the 200-Area Safety Analysis (DPSTSA-200-10). These supplements are numbered as Sup 2A, Scrap Recovery Facility, Sup 2B, Neptunium Oxide Facility, Sup 2C, Plutonium Oxide Facility. The subject of this safety analysis, the, Plutonium Oxide Facility, will convert nitrate solutions of {sup 238}Pu to plutonium oxide (PuO{sub 2}) powder. All these new facilities incorporate improvements in: (1) engineered barriers to contain contamination, (2) barriers to minimize personnel exposure to airborne contamination, (3) shielding and remote operations to decrease radiation exposure, and (4) equipment and ventilation design to provide flexibility and improved process performance.

    Europe has the world's most extensive network of conservation areas. Conservation areas are selected without taking into account the effects of climate change. How effectively would such areas conserve biodiversity under climate change? We assess the effectiveness of protected areas and the Natura 2000 network in conserving a large proportion of European plant and terrestrial vertebrate species under climate change. We found that by 2080, 58 ± 2.6% of the species would lose suitable climate in protected areas, whereas losses affected 63 ± 2.1% of the species of European concern occurring in Natura 2000 areas. Protected areas are expected to retain climatic suitability for species better than unprotected areas (P<0.001), but Natura 2000 areas retain climate suitability for species no better and sometimes less effectively than unprotected areas. The risk is high that ongoing efforts to conserve Europe's biodiversity are jeopardized by climate change. New policies are required to avert this risk. PMID:21447141

    Full Text Available During the last 20 years some keywords have been extensively used in international debate about local development policies: bottom-up approach, territoriality, policy integration, partnership, cooperation and negotiation among actors and interests. The use of these keywords hides a variety of cultural approaches, theories and practices; this means that we should study local development processes and policies analysing and deconstructing these theoretical approaches in specific situations and experiences. Within this framework, the article critically discuss local development policies involving “fragile” areas like those of the mountains in Lombardy. Reference will be made mainly to the results of a research-action activity on the integrated local development programmes (PISL for the Objective 2 areas of the Region financed during the period of European structural funds programming 2000-2006.Durant les vingt dernières années, quelques mots-clés ont été intensivement employés dans le débat international sur les politiques de développement local : bottom-up approach, territorialité, intégration politique, association, coopération et négociation entre les acteurs et les intérêts.

  18. AIR POLLUTION OF URBAN AREAS

    Directory of Open Access Journals (Sweden)

    MAKAROVA V. N.

    2016-04-01

    Full Text Available Raising of problem. Any manufacturing processes related to the generation of waste. Year after year, a growing mass of waste is one of the main factors reducing the quality of the environment and destruction of natural landscapes. Industrial development inevitably enhances human impacts on the environment and disrupts the ecological balance [3]. Atmospher air is a vital element of the environment. The development of industry, the growth of cities, increasing the number of transport, active exploration of near-Earth space lead to a change in the gas composition of the atmosphere and disruption of its natural balance. Air quality affects the health of the population [5]. Without water or food a person can do for a while, but without air he can not live a few minutes, therefore saving air breathable is an urgent problem. Purpose. The results of geological studies clearly indicate that the contamination of the surface layer of the atmosphere is the most powerful permanent factor of influence on the human food chain and the environment. This problem was reflected in the scientific literature [2; 3; 6], and the second significant indicator of ecological well-being of the region is the number of generation and accumulation of waste. According to this indicator, Dnipropetrovsk region is in the lead, as relates to the industrialized regions. The idea of the article is to consider the air pollution of the urban environment in terms of the accumulation of waste in the territory of enterprises, in particular slag dumps metallurgical production. Conclusion. Slag dumps located on the premises are a significant source of air pollution urbanized areas due to the permanent nature of the spread of contamination. Slag dump of PAT "Nikopol Ferroalloy Plant" is a source of manganese, zinc, nickel emissions. As a conclusion about the magnitude of pollution of the atmospheric boundary layer can say the following: on the border of the sanitary protection zone (SPZ, in

    2012-04-01

    Sampling was performed in July-August 2005-2010 at Station Sain Shand (44°54'N, 110°07'E) in the Gobi desert (1000 m a.s.l.), West Mongolia. Aerosol samples were collected with a high volume sampler PM 10 (Andersen Instruments Inc., USA) onto Whatman-41 filters. The substance was extracted from the filters by de-ionized water. The solution was screened through an acetate-cellulose filter with 0.2 micron pore size. Ions of ammonium, sodium, potassium, magnesium, and calcium, as well as sulphate ions, nitrate ions, hydrocarbonate, chloride ions were determined in the filtrate by means of an atomic adsorption spectrometer Carl Zeiss Jena (Germany), a high performance liquid chromatographer «Milichrome A-02» (Russia), and an ionic chromatographer ICS-3000 (Dionex, USA). The PAH fraction was separated from aerosol samples using hexane extraction at room temperature under UV environment. The extract was concentrated to 0.1-0.2 ml and analysed by a mass-spectrometer "Agilent, GC 6890, MSD 5973 Network". Analysis of concentrations of aerosols components, their correlation ratios, and meteorological modeling show that the main factor affecting chemical composition of aerosols is a flow of contaminants transferred by air masses to the sampling area mainly from the south and south-east, as well as wind conditions of the area, dust storms in particular. Sulphate, nitrate, and ammonium are major ions in aerosol particles at Station Sain Shand. Dust-borne aerosol is known to be a sorbent for both mineral and organic admixtures. Polycyclic aromatic hydrocarbons (PAH) being among superecotoxicants play an important role among resistant organic substances. PAH concentrations were determined in the samples collected in 2010. All aerosol samples contained dominant PAHs with 5-6 benzene rings ( (benze(k)fluoranthen, benze(b)flouranthen, benze(a)pyren, benze(?)pyren, perylene, benze(g,h,i)perylene, and indene(1,2,3-c,d)pyrene). Their total quantity varied between 42 and 90

  3. Plague in the genomic area.

    Drancourt, M

    2012-03-01

    With plague being not only a subject of interest for historians, but still a disease of public health concern in several countries, mainly in Africa, there were hopes that analyses of the Yersinia pestis genomes would put an end to this deadly epidemic pathogen. Genomics revealed that Y. pestis isolates evolved from Yersinia pseudotuberculosis in Central Asia some millennia ago, after the acquisition of two Y. pestis-specific plasmids balanced genomic reduction parallel with the expansion of insertion sequences, illustrating the modern concept that, except for the acquisition of plasmid-borne toxin-encoding genes, the increased virulence of Y. pestis resulted from gene loss rather than gene acquisition. The telluric persistence of Y. pestis reminds us of this close relationship, and matters in terms of plague epidemiology. Whereas biotype Orientalis isolates spread worldwide, the Antiqua and Medievalis isolates showed more limited expansion. In addition to animal ectoparasites, human ectoparasites such as the body louse may have participated in this expansion and in devastating historical epidemics. The recent analysis of a Black Death genome indicated that it was more closely related to the Orientalis branch than to the Medievalis branch. Modern Y. pestis isolates grossly exhibit the same gene content, but still undergo micro-evolution in geographically limited areas by differing in the genome architecture, owing to inversions near insertion sequences and the stabilization of the YpfPhi prophage in Orientalis biotype isolates. Genomics have provided several new molecular tools for the genotyping and phylogeographical tracing of isolates and description of plague foci. However, genomics and post-genomics approaches have not yet provided new tools for the prevention, diagnosis and management of plague patients and the plague epidemics still raging in some sub-Saharan countries.

  4. Locating ATMs in Urban Areas

    Full Text Available In recent years, the banks and financial institutions have considerably attempted to provide better and more varied services to the customers. These varied services may satisfy needs of differentgroup of customers. In this regard, the location of these services as well as their level of accessibility (access to these services is greatly important. The importance of these issues is well recognized by responsible managers of the financial firms. In other words, the managers accept the importance of these services and they know that the quality and location of these services significantly affect their success in the business. Therefore, bank managers sought scientific methods, which may facilitate the locating process for their services. How to select the most effective methods and how to use these methods in this regard depend on following factors: the customers' demands, local capacities and fair distribution of theservices, etc. The effective impact of these factors as well as the interactive relationship between them should also be noted in the application. This study is a descriptive kind of research, which is applicable in various areas. Library and environmental studies were used to conduct the study. Considering the parameters that considerably affect the level of acceptability of ATMs services and analyzing the importance of these parameters according to this criterion, the researchers tried to use multiple attribute decision-making model. a heuristic algorithm was used in the context of this approach. Then, the most appropriate locations around the optimal locations were introduced based on fuzzy concept as well as quantitative and qualitative factors, including the minimum cost and maximum coverage according to the customers’ demands. The case study was located in the 13th district of Tehran city.

    Science.gov (United States)

    Segerstrom, Kenneth; Weisner, R.C.

    1984-01-01

    On the basis of a mineral survey, most of the Laramie Peak Wilderness study area in Wyoming was concluded to have little promise for the occurrence of mineral or energy resources. Only three small areas in the northern part, one extending outside the study area to Esterbrook, were found to have probable mineral-resource potential for copper and lead. The geologic setting precludes the presence of fossil-fuel resources in the study area. There are no surface indications that geothermal energy could be developed within or near the study area.

  11. Early Paleozoic paleogeography of Laurentia and western Gondwana: Evidence from tectonic subsidence analysis

    Science.gov (United States)

    Williams, Kenneth E.

    1997-08-01

    A number of terranes were present in the early Paleozoic ocean between Laurentia and Gondwana following rifting. The precise location of these microcontinents and island arcs is unclear. We present tectonic subsidence curves from selected basins that may provide some constraints on the possible paleogeographic interpretations for this time interval. Among these tectonic blocks were the Precordillera terrane that originated in the Ouachita area of Laurentia and the composite Avalon-Carolina terrane that was derived from the Gondwana margin. Also present were the island-arc terranes of Famatina, Mixteca, and Zapoteca. The Precordillera and Famatina terranes are currently located in southern South America. The Avalon-Carolina terrane is in eastern North America. The Mixteca and Zapoteca terranes are in Central America. A review of previous work augmented by new tectonic subsidence analysis indicates that these terranes were swept up by early Paleozoic plate movements and were translated to approximately their present relative positions by the Early Carboniferous.

  12. TOURISM IN THE TOURIST AREA "IRON GATES"

    2015-12-01

    Full Text Available This paper wants to highlight the trends of tourist demanding from the touristic area Iron Gates. We will see that the future of tourism include new forms such as those caused by the increased interest in areas with agritourism attractions or areas and portions of parks and nature reserves, which will raise the attractiveness of Danube, putting in a new pole of attraction area. Thus, we conducted a research based on survey among visitors on the tourist area "Iron Gates". The main endpoint based on survey was highlighting the motivation that determined the choice of the tourist area "Iron Gates", but also knowledge of consumer satisfaction for the tourists to the visited area (tourist product studied. The main objectives were, of course, linked with socio - economic and demographic characteristics of tourists to form a clearer picture of the motivational factors involved.

  13. Area metric gravity and accelerating cosmology

    CERN Document Server

    Punzi, R; Wohlfarth, M N R; Punzi, Raffaele; Schuller, Frederic P.; Wohlfarth, Mattias N.R.

    2007-01-01

    Area metric manifolds emerge as effective classical backgrounds in quantum string theory and quantum gauge theory, and present a true generalization of metric geometry. Here, we consider area metric manifolds in their own right, and develop in detail the foundations of area metric differential geometry. Based on the construction of an area metric curvature scalar, which reduces in the metric-induced case to the Ricci scalar, we re-interpret the Einstein-Hilbert action as dynamics for an area metric spacetime. In contrast to modifications of general relativity based on metric geometry, no continuous deformation scale needs to be introduced; the extension to area geometry is purely structural and thus rigid. We present an intriguing prediction of area metric gravity: without dark energy or fine-tuning, the late universe exhibits a small acceleration.

    The issues related to the appropriate planning of the territory are particularly pronounced in highly inhabited areas (urban areas), where in addition to protecting the environment, it is important to consider an anthropogenic (urban) development placed in the context of sustainable growth. This work aims at mathematically simulating the changes in the land use, by implementing an artificial neural network (ANN) model. More specifically, it will analyze how the increase of urban areas will develop and whether this development would impact on areas with particular socioeconomic and environmental value, defined as multifunctional areas. The simulation is applied to the Chianti Area, located in the province of Florence, in Italy. Chianti is an area with a unique landscape, and its territorial planning requires a careful examination of the territory in which it is inserted.

    Johnson, Bruce R.; Ellis, Clarence E.

    1984-01-01

    Mineral surveys were undertaken of a wilderness study area which includes most of the Sangre de Cristo Range of south-central Colorado. Four areas of probable mineral-resource potential for gold, silver, and base metals lie along a northwest structural trend which follows the western margin of the range north of the Great Sand Dunes National Monument and crosses the range south of the monument. An area of probable mineral-resource potential for similar minerals plus tungsten has been identified east of Blanca Peak at the extreme southern end of the study area. Another area of probable mineral-resource potential includes molybdenum mineralization associated with the Rito Alto stock. A small area of probable geothermal resource potential exists on the west side of the area around the Valley View Hot Springs. There is little promise for the occurrence of oil and gas resources.

  16. Overcoming the isolation of disadvantaged housing areas

    DEFF Research Database (Denmark)

    Stender, Marie; Bech-Danielsen, Claus

    Disadvantaged social housing areas in Denmark are currently subject to more thorough physical refurbishments, aiming to overcome the isolated character of the housing estates. The ambition is to attract new users and residents by opening up the borders of the area and establish attractive, new...... penthouse flats, new urban functions within the area or spectacular new public spaces near it. In this paper the social impact of such transformations are analysed and discussed based on case-studies in 3 Danish areas. The analysis shows that especially everyday-route strategies adding new public functions...... within the area can pave can the way for integration with the surroundings. The applicability of such strategies is however highly dependent on context, location and existing image. Social distance may sustain though physical borders are removed, yet, the negative image of the areas can in itself call...

    -dimensional measurements of selected linear distances, curve lengths, and (surface) areas were carried out on maxillary plaster casts from individuals with unilateral or bilateral cleft lip and palate. The relationship between two-dimensional and three-dimensional measurements was investigated using linear regression....... Results and Conclusions: Error sources in the measurement of three-dimensional palatal segment surface area from a two-dimensional photograph were identified as photographic distortion (2.7%), interobserver error (3.3%), variability in the orientation of the plaster cast (3.2%), and natural shape...... variation (4.6%). The total error of determining the cleft area/palate surface area ratio was 15%. In population studies, the effect of using two-dimensional measurements is a decrease of discriminating power. In well-calibrated setups, a two-dimensional measurement of the cleft area/palate surface area...

  19. Body Surface Area Prediction in Odorrana grahami

    Guiying CHEN; Jiongyu LIU; Qiang DAI; Jianping JIANG

    2014-01-01

    Body surface area (BSA) was regarded as a more readily quantiifable parameter relative to body mass in the normalization of comparative biochemistry and physiology. The BSA prediction has attracted unceasing research back more than a century on animals, especially on humans and rats. Few studies in this area for anurans were reported, and the equation for body surface area (S) and body mass (W):S=9.9 W 0.56, which was concluded from toads of four species in 1969, was generally adopted to estimate the body surface areas for anurans until recent years. However, this equation was not applicable to Odorrana grahami. The relationship between body surface area and body mass for this species was established as:S=15.4 W 0.579. Our current results suggest estimation equations should be used cautiously across different species and body surface area predictions on more species need to be conducted.

    Geologic mapping, geochemical sampling, and a search for prospects and mineralized rock in the Box-Death Hollow Roadless Area, Utah indicate that there is little promise for the occurrence of mineral or energy resources in the area. Additional exploratory drilling by industry seems warranted if wells elsewhere in the region find oil or gas in strata as yet untested in the Box-Death Hollow Roadless Area.

  4. Drainage area data for Alabama streams

    Science.gov (United States)

    Stallings, J.S.; Peirce, L.B.

    1957-01-01

    The drainage area of a river basin is an important parameter in many engineering equations used for hydrologic design. It is not a parameter, however, that always requires precise measurement. Factors in the hydrologic cycle such as rainfall, runoff, transpiration, and infiltration cannot be measured nearly as closely as drainage area. Largely for this reason, drainage areas are often measured to varying degrees of precision depending upon the immediate need, with little thought to some other use or some other user of the figure obtained. It can readily be appreciated that this practice, continued for long by many different agencies, will result in a heterogeneous collection of drainage area figures, often discordant and of an accuracy unknown to any but those who computed them. Figures of drainage area published by various Federal agencies are frequently discrepant or contradictory, giving rise to confusion in the use of drainage area data. Seeking to better this situation, the Federal Inter-Agency River Basin Committee (FIARBC) in November 1951 published its Bulletin No. 4, Inter-Agency Coordination of Drainage Area Data. That Bulletin recommended procedures to be followed by the interested Federal agencies “for coordinating drainage area data in the interest of promoting uniformity, reducing confusion and contradiction of published figures, and improving the ready availability of drainage area data pertaining to drainage basins of the United States and its possessions.”

  5. Estimation of Poverty in Small Areas

    2014-12-01

    Full Text Available A qualitative techniques of poverty estimation is needed to better implement, monitor and determine national areas where support is most required. The problem of small area estimation (SAE is the production of reliable estimates in areas with small samples. The precision of estimates in strata deteriorates (i.e. the precision decreases when the standard deviation increases, if the sample size is smaller. In these cases traditional direct estimators may be not precise and therefore pointless. Currently there are many indirect methods for SAE. The purpose of this paper is to analyze several diff erent types of techniques which produce small area estimates of poverty.

    2007-01-01

    We provide further crucial support for a refined, area metric structure of spacetime. Based on the solution of conceptual issues, such as the consistent coupling of fermions and the covariant identification of radiation fields on area metric backgrounds, we show that the radiation-dominated epoch of area metric cosmology is equivalent to that epoch in standard Einstein cosmology. This ensures, in particular, successful nucleosynthesis. This surprising result complements the previously derived prediction of a small late-time acceleration of an area metric universe.

    2002-01-01

    Encountered in the literature generalisations of general relativity to independent area variables are considered, the discrete (generalised Regge calculus) and continuum ones. The generalised Regge calculus can be either with purely area variables or, as we suggest, with area tensor-connection variables. Just for the latter, in particular, we prove that in analogy with corresponding statement in ordinary Regge calculus (by Feinberg, Friedberg, Lee and Ren), passing to the (appropriately defined) continuum limit yields the generalised continuum area tensor-connection general relativity.

  13. Youthification in the Metropolitan Area of Cluj

    Directory of Open Access Journals (Sweden)

    Vlad Cocheci

    2018-06-01

    Full Text Available This research exercise aims to identify all areas affected by what is now known as ‘youthification’ in the Metropolitan Area of Cluj. Broadly speaking, an area touched by youthification witnesses a massive arrival of young adults, who invest in housing, but only remain there until they age. Youthification is usually the second phase within an encompassing process of gentrification. To gain a clearer picture of this phenomenon, we employed a snapshot of the situation recorded by the Population and Housing Census of 2011. Using this image as a starting point, we then applied statistical thresholds aimed at measuring the presence and intensity of youthification within different areas. Thereafter, we looked at areas exhibiting the same level of youthification, in order to find those common traits of their young adult inhabitants that might prove relevant for their choices in matters of housing. Once completed, our efforts resulted in the first map showing the areas affected by youthification within the Metropolitan Area of Cluj. In addition, we reached the following conclusion: Young adults who live in the city are more likely to still be enrolled in a form of education and less likely to be married or to have children than those who live in the suburbs or in rural areas. This observation implies that there might be some hidden dependency relations, which are at work in shaping the choice of housing.

    Clausen, Anders; Aage, Niels; Sigmund, Ole

    2014-01-01

    This paper presents a methodology for including fixed-area flexible void domains into the minimum compliance topology optimization problem. As opposed to the standard passive elements approach of rigidly specifying void areas within the design domain, the suggested approach allows these areas...... to be flexibly reshaped and repositioned subject to penalization on their moments of inertia, the positions of their centers of mass, and their shapes. The flexible void areas are introduced through a second, discrete design variable field, using the same discretization as the standard field of continuous...... density variables. The formulation is based on a combined approach: The primary sub-problem is to minimize compliance, subject to a volume constraint, with a secondary sub-problem of minimizing the disturbance from the flexible void areas. The design update is performed iteratively between the two...

  11. Geometry of manifolds with area metric

    CERN Document Server

    Schuller, F P

    2005-01-01

    We construct the differential geometry of smooth manifolds equipped with an algebraic curvature map acting as an area measure. Area metric geometry provides a spacetime structure suitable for the discussion of gauge theories and strings, and is considerably more general than Lorentzian geometry. Our construction of geometrically relevant objects, such as an area metric compatible connection and derived tensors, makes essential use of a decomposition theorem due to Gilkey, showing that a general area metric is generated by a finite collection of metrics rather than by a single one. Employing curvature invariants for area metric manifolds we devise an entirely new class of gravity theories with inherently stringy character, and discuss gauge matter actions.

    Panxi Area is abundant in plant resources, among which toxic plants are of great value in terms of exploitation. This paper is an initiative study (via field as well as literature investigation) of the categories, distributions, and reserves of toxic plant resources in Panxi Area. The study reveals that there are 51 families (210 species) of toxic plants evenly distributed in Panxi Area, of which more than 40 species grow in all counties in the area, and more than 14 species total a reserve more than 1.0×105kg. These toxic plants are of great applications to medicine, gardening, biopesticide industry, environmental engineering, and oil manufacturing. Rhododendron molle, Anisodus acutangulus, Arisaema erubesocens, Stellera chamaejasme, Rhytolacca acinosa, Rheum officinale, and Azadiralta indica etc are the typical toxic plants with great value of exploitation in Panxi Area.

    2010-02-01

    Cortical-surface-based functional Magnetic Resonance Imaging mapping techniques and wide-field retinotopic stimulation were used to verify the presence of pattern motion sensitivity in human area V6. Area V6 is highly selective for coherently moving fields of dots, both at individual and group levels and even with a visual stimulus of standard size. This stimulus is a functional localizer for V6. The wide retinotopic stimuli used here also revealed a retinotopic map in the middle temporal cortex (area MT/V5) surrounded by several polar-angle maps that resemble the mosaic of small areas found around macaque MT/V5. Our results suggest that the MT complex (MT+) may be specialized for the analysis of motion signals, whereas area V6 may be more involved in distinguishing object and self-motion.

    Software companies are increasingly offshoring development to countries with high expertise at lower cost. Offshoring involves particular risk areas that if ignored increase the likelihood of failure. However, the offshoring client’s maturity level may influence the management of these risk areas.......

We find that managers perceive and mitigate most...... of the offshoring risk areas in accordance with the findings of previous research. However, the risk area of task distribution is a notable exception. In this case, managers perceive high task uncertainty, equivocality, and coupling across sites as risk mitigation rather than risk taking. The paper discusses how...

    We have developed a new gaseous radiation detector, referred to as the Glass GEM (G-GEM). The G-GEM is composed of a photosensitive etching glass (PEG3) substrate from HOYA Corporation, Japan. Since a large-area detector is required for imaging device applications, we newly developed a large-area G-GEM prototype with a sensitive area of 280×280 mm{sup 2}. In this study, we investigated its basic characteristics and confirmed that it worked properly and had sufficient uniformity across the entire sensitive area. It had high gas gain of up to approximately 7700, along with good energy resolution of 26.2% (FWHM) for a 5.9-keV X-ray with a gas mixture of Ar (90%) and CH4 (10%). The gain variation across the sensitive area was almost within the range of ±10%.

    Science.gov (United States)

    Bousso, Raphael; Engelhardt, Netta

    2015-08-21

    We report a new area law in general relativity. A future holographic screen is a hypersurface foliated by marginally trapped surfaces. We show that their area increases monotonically along the foliation. Future holographic screens can easily be found in collapsing stars and near a big crunch. Past holographic screens exist in any expanding universe and obey a similar theorem, yielding the first rigorous area law in big bang cosmology. Unlike event horizons, these objects can be identified at finite time and without reference to an asymptotic boundary. The Bousso bound is not used, but it naturally suggests a thermodynamic interpretation of our result.

    The recent dramatic rise in power conversion efficiencies (PCE) of perovskite solar cells has triggered intense research worldwide. However, their practical development is hampered by poor stability and low PCE values with large areas devices. Here, we developed a gas-pumping method to avoid pinholes and eliminate local structural defects over large areas of perovskite film, even for 5 × 5 cm2 modules, the PCE reached 10.6% and no significant degradation was found after 140 days of outdoor testing. Our approach enables the realization of high performance large-area PSCs for practical application.

  1. Green tribology: principles, research areas and challenges.

    Science.gov (United States)

    Nosonovsky, Michael; Bhushan, Bharat

    2010-10-28

    In this introductory paper for the Theme Issue on green tribology, we discuss the concept of green tribology and its relation to other areas of tribology as well as other 'green' disciplines, namely, green engineering and green chemistry. We formulate the 12 principles of green tribology: the minimization of (i) friction and (ii) wear, (iii) the reduction or complete elimination of lubrication, including self-lubrication, (iv) natural and (v) biodegradable lubrication, (vi) using sustainable chemistry and engineering principles, (vii) biomimetic approaches, (viii) surface texturing, (ix) environmental implications of coatings, (x) real-time monitoring, (xi) design for degradation, and (xii) sustainable energy applications. We further define three areas of green tribology: (i) biomimetics for tribological applications, (ii) environment-friendly lubrication, and (iii) the tribology of renewable-energy application. The integration of these areas remains a primary challenge for this novel area of research. We also discuss the challenges of green tribology and future directions of research.

  4. Optimizing sales areas of combined transport chains

    Directory of Open Access Journals (Sweden)

    Philip Michalk

    2013-12-01

    Full Text Available Background: Combined transport chains (such as intermodal transport, have certain advantages. The main advantage from customer points of view is the possibility to bundle freight and thereby decrease transport costs. On the other hand, a combined transport chain can cause longer transport times, due to the necessary transshipment processes. Methods: The area around a terminal, in which a combined service has favourable properties to a customer in comparison to a direct transport, can be understood as a sales-area, in which a combined transport product is marketable. The aim of this paper was to find a method to determine the best shape and size of this area. Results and conclusions: The paper at hand lined out a method in order to calculate such a sales area and determine which geographical points around a terminal have an advantage in comparison to a direct transport service.

    The Central Facilities Area (CFA) located in Butte County, Idaho at Idaho National Laboratory (INL) has an existing wastewater system to collect and treat sanitary wastewater and non contact cooling water from the facility. The existing treatment facility consists of three cells: Cell 1 has a surface area of 1.7 acres, Cell 2 has a surface area of 10.3 acres, and Cell 3 has a surface area of 0.5 acres. If flows exceed the evaporative capacity of the cells, wastewater is discharged to a 73.5 acre land application site that utilizes a center pivot irrigation sprinkler system. The purpose of this current study is to update the analysis and conclusions of the December 2013 study. In this current study, the new seepage rate and influent flow rate data have been used to update the calculations, model, and analysis.

  13. Localization of cortical areas activated by thinking

    DEFF Research Database (Denmark)

    Roland, P E; Friberg, L

    1985-01-01

    These experiments were undertaken to demonstrate that pure mental activity, thinking, increases the cerebral blood flow and that different types of thinking increase the regional cerebral blood flow (rCBF) in different cortical areas. As a first approach, thinking was defined as brain work...... that they started at their front door and then walked alternatively to the left or the right each time they reached a corner. The rCBF increased only in homotypical cortical areas during thinking. The areas in the superior prefrontal cortex increased their rCBF equivalently during the three types of thinking...... midtemporal cortex exclusively during jingle thinking. The intermediate and remote visual association areas, the superior occipital, posterior inferior temporal, and posterior superior parietal cortex, increased their rCBF exclusively during route-finding thinking. We observed no decreases in rCBF. All r...

  16. Improving the environment in urban areas

    Energy Technology Data Exchange (ETDEWEB)

    Adamkus, V.V.

    1994-12-31

    The author discusses the need for improvements to the environment in urban areas, and efforts being made under the direction of the Environmental Protection Agency (EPA) to address these problems. The impact the new Clean Air Act can have on emissions from gasoline powered autos, diesel burning trucks, fixed emission sources ranging from utilities to chemical plants, and consumer products like hair sprays and charcoal starters, will all work together to improve air quality in urban areas. The author also discusses Brownfields Economic Redevelopment Plan efforts being supported by the EPA in a coordinated plan to get municipalities involved in cleaning up areas with pollution, to remove the blight on the urban areas, provide new land for development, and promote additional jobs.

  17. WHITE CLOUD-BOULDER ROADLESS AREA, IDAHO.

    Science.gov (United States)

    Fisher, Frederick S.; Johnson, Fredrick L.

    1984-01-01

    There have been no minerals produced from, and there are no mines located within the White Cloud-Boulder Roadless Area, Idaho; however, based on mineral studies, the southern part of the roadless area has a probable resource potential for tungsten and the northwestern corner a probable resource potential for gold and silver. The conclusions are based on the presence of favorable geologic environments for calc-silicate skarns in the southern part of the roadless area and the presence of gold-bearing quartz-carbonate veins in the northern part. The northern part of the area in the vicinity of Sheep Mountain-Bowery Peak has a probable resource potential for arsenic, copper, gold, lead, molybdenum, silver, tin, and zinc, on the basis of geologic and geophysical data that suggest the presence of a buried intrusive body which probably has associated ore deposits. No energy resources were identified in the study.

    We present an interface area transport model required in tracking of mass, momentum, and energy exchange between dispersed and background materials. The basic transport equation has been rigorously derived from the volume fraction evolution equation. Interface area changes due to mass transport and local compression/expansion are included. The model is then simplified for the case in which the dispersed phase is composed of spheres of locally uniform size. A procedure for calculating advective flux with interface reconstruction has been suggested.

  15. Sensory brain areas in mesopelagic fishes.

    Science.gov (United States)

    Wagner, H J

    2001-03-01

    Four areas of the brain that receive primary projections from chemical senses ([1] olfactory bulb, [2] facial and vagal lobes), the eye ([3] optic tectum), and somato- and mechanosensory systems such as the lateral line, vestibular and auditory systems ([4] trigeminal and octavolateral regions) have been studied and relative size differences used to deduce the sensory specializations of 67 species of mesopelagic fishes. One type of analysis used the average relative volumes of brain areas and identified 'specialists' with only one brain area above-average (36%), species 'dominated' by two sensory brain regions (49%), and generalists (15%), with three areas above-average. In addition, a cluster analysis was performed that separated 49 species which were mostly visually oriented from 18 non-visual species, among which 16 were characterized by an association of above-average trigeminal/octavolateral and gustatory areas, and a single species with a dominant olfactory bulb. The results support the idea that these species occupy a rich sensory environment for which the absence of sunlight is compensated by chemical and mechanosensory stimuli as well as by bioluminescent signals. This has lead to the development of specializations for the perception of single stimulus-modes, most notably for the visual system, as well as for combinations of various receptors and central processing areas, with a preference for associating either the chemical senses, including the olfactory and facial/vagal systems, or the trigeminal/octavolateral systems.

    This report is part of the scientific basis for the management plan for the North Sea and Skagerrak. The report focuses on the vulnerability of particularly valuable areas to petroleum activities, maritime transport, fisheries, land-based and coastal activities and long-range transboundary pollution. A working group with representatives from many different government agencies, headed by the Institute of Marine Research and the Directorate for Nature Management, has been responsible for drawing up the present report on behalf of the Expert Group for the North Sea and Skagerrak. The present report considers the 12 areas that were identified as particularly valuable during an earlier stage of the management plan process on the environment, natural resources and pollution. There are nine areas along the coast and three open sea areas in the North Sea that were identified according to the same predefined criteria as used for the management plans for the Barents Sea: Lofoten area and the Norwegian Sea. The most important criteria for particularly valuable areas are importance for biological production and importance for biodiversity.(Author)

    The methodology for classifying areas according to soil properties for the vulnerability to a {sup 137}Cs contamination is of high importance to the preparedness related to nuclear and/or radiological accidents that lead to release of radionuclides to the environment with the consequent contamination of agricultural areas. The priority of research for agricultural areas should then focus on the surrounding areas of nuclear power plant that have higher probability of public exposure through the ingestion pathway. The objective of this work was to create a rank order for priority of areas to be mapped based on EMBRAPA database on soil properties. The 16 municipalities previously selected to define parameters for dose assessment simulations related to the Brazilian Nuclear Power Plants, located in the district of Angra dos Reis, Rio de Janeiro, have been investigated in order to create this rank order to direct the research on radio vulnerability mapping, considering their relevance to public exposure based on their agricultural productivity. The two aspects selected in this study account for the maximum loss of income and to the collective doses that can be averted due to the banning of agricultural products. These quantities are inputs to optimization analysis. The priority defined shall then guide research on both the adequate values for the transfer factors and on the agricultural countermeasures suitable to each area according to the cause(s) of their vulnerability and their typical agricultural crops.

  19. Estimating Tree Frontal Area in Urban Areas Using Terrestrial LiDAR Data

    2016-05-01

    Full Text Available Surface roughness parameters, such as roughness length and displacement height, impact the estimation of surface moisture, and the frontal areas of buildings and trees are two components that contribute to surface roughness in urban areas. Research on tree frontal area has not been conducted in urban areas before, and we hope to fill that gap in the literature with this study by using Terrestrial Light Detection and Ranging (LiDAR data to estimate tree frontal areas in Warren Township, Indianapolis, IN, USA. We first estimated the frontal areas of individual trees based on their morphology, then calibrated a regression model to estimate the tree frontal area in 30 m pixels using parameters derived from LiDAR data and tree inventory data. The parameters included tree crown base area, height, width, conditions, defects, maintenances, genera, and land use. The validation shows that R2 yielded values ranging from 0.84 to 0.88, and RMSEs varied with tree category. The tree categories were identified based on the height and broadness of the canopy, which indicated the degree of resistance to air flow. This type of model can be used to empirically determine local roughness values at the tree-level for any city with a complete tree inventory. With the strong correlation between trees’ frontal area and crown base area, this model may also be used to determine local roughness value at 30 m resolution with NLCD (National Land Cover Database tree canopy cover data as a component. A proper tree categorization according to the vertical air resistance, e.g., height and canopy density, was effective to reduce the RMSE in tree frontal area estimation. Geometric parameters, such as height, crown base height, and crown base area extracted from Airborne LiDAR, which demand less storage and computation capacity, may also be sufficient for tree frontal area estimation in the areas where Terrestrial LiDAR is not available.

    Full Text Available Approaches to the consideration of functions of specially protected natural areas (SPNA in the development of society seek to determine the size of the territory withdrawn from agricultural use for the purposes of nature conservation; these approaches also aim to evaluate money revenue gained from these territories. However, the influence of SPNA on public life is not reduced to the “monetization” of the territory. People who live near conservation areas and experience the advantages (disadvantages of such neighbourhood should be the focus of the study of the social role of protected areas. The social role of SPNA in the life of local communities in the Arkhangelsk Oblast and the Karelia Republic was identified with the help of public opinion survey. In total 575 people participated in the survey. The research was carried out in the settlements located within the boundaries of Kenozersky and Vodlozersky national parks, and near Shilovsky Nature Reserve. When measuring the impact of conservation areas on the society of the neighbouring settlements, the authors define the axiological, emotional-and-psychological, activityand-regulatory, economic, forecasting and integrated components. The research findings show that the residents acknowledge the conservation value of protected areas; many of the inhabitants of adjacent territories do not experience inconveniences in connection with the special environmental regime, they earn income connected to the operation of SPNA; there is a positive attitude towards the activity of SPNA. If these areas cease functioning, then one third of the respondents expect negative changes in their life. Specially protected natural areas contribute to the socio-cultural and spiritual development of the local community to a greater extent in comparison with its socio-economic development. The presence of SPNA on the territory of the municipality opens up opportunities for new types of economic activities, provides

    2012-12-31

    The Driftless Area Initiative Biomass Energy Project evaluated the potential for biomass energy production and utilization throughout the Driftless Region of Illinois, Iowa, Minnesota and Wisconsin. The research and demonstration aspect of the project specifically focused on biomass energy feedstock availability and production potential in the region, as well as utilization potential of biomass feedstocks for heat, electrical energy production, or combined heat and power operations. The Driftless Region was evaluated because the topography of the area offers more acres of marginal soils on steep slopes, wooded areas, and riparian corridors than the surrounding “Corn Belt”. These regional land characteristics were identified as potentially providing opportunity for biomass feedstock production that could compete with traditional agriculture commodity crops economically. The project researched establishment methods and costs for growing switchgrass on marginal agricultural lands to determine the economic and quantitative feasibility of switchgrass production for biomass energy purposes. The project was successful in identifying the best management and establishment practices for switchgrass in the Driftless Area, but also demonstrated that simple economic payback versus commodity crops could not be achieved at the time of the research. The project also analyzed the availability of woody biomass and production potential for growing woody biomass for large scale biomass energy production in the Driftless Area. Analysis determined that significant resources exist, but costs to harvest and deliver to the site were roughly 60% than that of natural gas at the time of the study. The project contributed significantly to identifying both production potential of biomass energy crops and existing feedstock availability in the Driftless Area. The project also analyzed the economic feasibility of dedicated energy crops in the Driftless Area. High commodity crop prices and

  3. EURO AREA FISCAL STRUCTURES. A MULTIVARIATE ANALYSIS

    Directory of Open Access Journals (Sweden)

    HURDUZEU Gheorghe

    2014-07-01

    Full Text Available The European framework for fiscal policies is constructed mainly on the objective of monitoring budget balances and public debt, allowing national governments to decide on the specific fiscal policy that is more suitable to their internal context and public needs. However, for Euro Area member states this autonomy is restricted by the conditions imposed through the Stability and Growth Pact. As the recent macroeconomic dynamics underlined the necesity of improving the fiscal outcomes, the fiscal framework was updated and modified by the provisions of the new European economic governance meant to avoid unsound and unsustainable fiscal policies that could affect the stability of other Euro Area member states. The Six-Pack, the Fiscal Compact and the other conditions imposed by the reform of the fiscal governance framework are meant to ensure more discipline in drafting and executing national budgets. Even so, national authorities maintain their fiscal sovereignty and the decision regarding fiscal structures remains at their disposal, as long as the drafts are approved and the outcomes are maintained in the limits imposed through the supranational fiscal framework. Regardless of the numerous differences between member states, similar trends regarding tax mixes can be noticed in time. The objectives of this paper is to analyze fiscal structures of Euro Area member states and to determine, if any, groups with similar fiscal structures, their composition and the similarities that characterize Euro Area in this respect. In order to have a clear overview of fiscal structures within Euro Area, we analyzed data for 17 member states, for year 2012, taking into consideration total general government revenue, indirect taxation, direct taxation and social contributions. As one of the aims of this paper is to determine whether in Euro Area the main contributors are corporations or individuals, we also analyzed the structure of direct taxation, dividing it into

    The focus of this study is on European nursing education, where there have been several reforms over the last two decades attempting to harmonise curricula and degree structures. One of the most powerful reforms was started by the Bologna Declaration in 1999; since then, significant progress has been made towards achieving the European Higher Education Area (EHEA) and the implementation of the European Qualifications Framework (EQF) in education practice. The Directive of recognition of professional qualifications (2005/36/EC) regulates nursing education. All these strategies aim to harmonise nursing education, but specific competence areas in nursing are still missing within the European Union (EU). The purpose of this review was to seek competence areas for nursing students within the EU as identified in previous studies and other documents. Altogether, 67 competence areas were identified and classified into eight main categories: (1) professional and ethical values and practice, (2) nursing skills and intervention, (3) communication and interpersonal skills, (4) knowledge and cognitive ability, (5) assessment and improving quality in nursing, (6) professional development, (7) leadership, management and teamwork, and (8) research utilisation. In order to obtain a comprehensive concept of competence, more research is needed on nursing students' competence areas across the EU due to the fact that the EU is a common labour market and nurses are educated for the EU as a whole. Nursing is a global profession and nurse competence is central to patient care outcomes, so it is also internationally important that nurses have good competence.

  5. Disseminating Ambient Assisted Living in Rural Areas

    Directory of Open Access Journals (Sweden)

    Gerhard Leitner

    2014-07-01

    Full Text Available The smart home, ambient intelligence and ambient assisted living have been intensively researched for decades. Although rural areas are an important potential market, because they represent about 80% of the territory of the EU countries and around 125 million inhabitants, there is currently a lack of applicable AAL solutions. This paper discusses the theoretical foundations of AAL in rural areas. This discussion is underlined by the achievements of the empirical field study, Casa Vecchia, which has been carried out over a four-year period in a rural area in Austria. The major goal of Casa Vecchia was to evaluate the feasibility of a specific form of AAL for rural areas: bringing AAL technology to the homes of the elderly, rather than moving seniors to special-equipped care facilities. The Casa Vecchia project thoroughly investigated the possibilities, challenges and drawbacks of AAL related to this specific approach. The findings are promising and somewhat surprising and indicate that further technical, interactional and socio-psychological research is required to make AAL in rural areas reasonable in the future.

    1997-12-31

    In order to close the two-fluid model for two-phase flow analyses, the interfacial area concentration needs to be modeled as a constitutive relation. In this study, the focus was on the investigation of the interfacial area concentration transport phenomena, both theoretically and experimentally. The interfacial area concentration transport equation for air-water bubbly up-flow in a vertical pipe was developed, and the models for the source and sink terms were provided. The necessary parameters for the experimental studies were identified, including the local time-averaged void fraction, interfacial area concentration, bubble interfacial velocity, liquid velocity and turbulent intensity. Experiments were performed with air-water mixture at atmospheric pressure. Double-sensor conductivity probe and hot-film probe were employed to measure the identified parameters. With these experimental data, the preliminary model evaluation was carried out for the simplest form of the developed interfacial area transport equation, i.e., the one-dimensional transport equation.

    2008-01-01

    Based on the polarization analysis of teleseismic SKS waveform data recorded at 49 seismic stations in Capital Area Seismograph Network, the SKS fast-wave direction and the delay time between the fast and slow shear waves at each station were determined by using the grid searching method of minimum transverse energy and the stacking analysis method, and then we acquired the image of upper mantle anisotropy in Capital area. In the study area, the fast-wave polarization direction is basically WNW-ESE, and the delay time falls into the interval from 0.56 s to 1.56 s. The results imply that the upper mantle anisotropy in Capital area is mainly caused by the subduetion of the Pacific plate to Eurasian plate. The subduction has resulted in the asthenospheric material deformation in Capital area, and made the alignment of upper mantle peridotite lattice parallel to the deformation direction. And the collision between the Indian and Eurasian plates made the crest of western China thickening and uplifting and material eastwards extruding, and then caused the upper mantle flow eastwards, and made the upper mantle deformation direction parallel to the fast-wave direction. The deformation model of the crust and upper mantle is possibly vertically coherent deformation by comparing the fast-wave polarization direction with the direction of lithospheric extension and the GPS velocity direction.

  8. Epidemiology of fascioliasis in human endemic areas.

    Mas-Coma, S

    2005-09-01

    Considered a secondary zoonotic disease until the mid-1990s, human fascioliasis is at present emerging or re-emerging in many countries, including increases of prevalence and intensity and geographical expansion. Research in recent years has justified the inclusion of fascioliasis in the list of important human parasitic diseases. At present, fascioliasis is a vector-borne disease presenting the widest known latitudinal, longitudinal and altitudinal distribution. Fasciola hepatica has succeeded in expanding from its European original geographical area to colonize five continents, despite theoretical restrictions related to its biology and in turn dependent upon environmental and human activities. Among the different epidemiological situations, human hypo- to hyperendemic areas, including epidemics, are noteworthy. A global analysis of the distribution of human cases shows that the expected correlation between animal and human fascioliasis only appears at a basic level. Areas presenting very high human prevalences and intensities, especially in children and females, have been recently described. In hypo- to hyperendemic areas of Central and South America, Europe, Africa and Asia, human fascioliasis presents a range of epidemiological characteristics related to a wide diversity of environments. Thus far well-known epidemiological patterns of fascioliasis may not always explain the transmission characteristics in any given area and control measures should consider the results of ecoepidemiological studies undertaken in the zones concerned.

    Cropland area estimation is a challenge, made difficult by the variety of cropping systems, including crop types, management practices, and field sizes. A MODIS derived indicator mapping product (1) developed from 16-day MODIS composites has been used to target crop type at national scales for the stratified sampling (2) of higher spatial resolution data for a standardized approach to estimate cultivated area. A global prototype is being developed using soybean, a global commodity crop with recent LCLUC dynamic and a relatively unambiguous spectral signature, for the United States, Argentina, Brazil, and China representing nearly ninety percent of soybean production. Supervised classification of soy cultivated area is performed for 40 km2 sample blocks using time-series, Landsat imagery. This method, given appropriate data for representative sampling with higher spatial resolution, represents an efficient and accurate approach for large area crop type estimation. Results for the United States sample blocks have exhibited strong agreement with the National Agricultural Statistics Service's (NASS's) Cropland Data Layer (CDL). A confusion matrix showed a 91.56% agreement and a kappa of .67 between the two products. Field measurements and RapidEye imagery have been collected for the USA, Brazil and Argentina in further assessing product accuracies. The results of this research will demonstrate the value of MODIS crop type indicator products and Landsat sample data in estimating soybean cultivated area at national scales, enabling an internally consistent global assessment of annual soybean production.

    In accordance with DOE Regulations for Compliance with Floodplain/Wetlands Environmental Review Requirements, wetland surveys were conducted in selected areas within the K-25 Area of Responsibility during the summer of 1994. These areas are Mitchell Branch, Poplar Creek, the K-770 OU, Duct Island Peninsula, the Powerhouse area, and the K-25 South Corner. Previously surveyed areas included in this report are the main plant area of the K-25 Site, the K-901 OU, the AVLIS site, and the K-25 South Site. Wetland determinations were based on the USACE methodology. Forty-four separate wetland areas, ranging in size from 0.13 to 4.23 ha, were identified. Wetlands were identified in all of the areas surveyed with the exception of the interior of the Duct Island Peninsula and the main plant area of the K-25 Site. Wetlands perform functions such as floodflow alteration, sediment stabilization, sediment and toxicant retention, nutrient transformation, production export, and support of aquatic species and wildlife diversity and abundance. The forested, scrub-shrub, and emergent wetlands identified in the K-25 area perform some or all of these functions to varying degrees.

    Full Text Available Priority sites within Japan Hotspot were identified using Key Biodiversity Area (KBA criteria, based on vulnerability and irreplaceability. The identification process considered 217 trigger species from mammals, birds, reptiles, amphibians, freshwater and brackish water fishes and odonates, and focused on identifying gaps in Japan’s protected-area system. We identified 228 sites as KBAs and 50 rivers as candidate KBAs. Collectively, KBAs occupy 18% of the land, about half is not protected. Sites selected include natural and semi-natural environments, and appropriate form of protection is site-dependent. Twenty percent of Japanese terrestrial area is already protected, although to varying degrees, but additional 8% should also receive protection or proper management to strengthen the conservation of biodiversity in Japan.

However......, redevelopment of these older business areas faces great challenges; especially compared to urban (re)development in general. The property structure and ownerships are often complex and need re-composition to meet new land uses, the soil may be polluted from former activities implying large clearing costs...... with a viable industrial production and no interest in moving out of the area. In such cases potential environmental conflicts can be foreseen between the ongoing enterprises and new sensitive land uses on adjacent sites.

    We explore the constraints following from requiring the Area Law in the entanglement entropy in the context of loop quantum gravity. We find a unique solution to the single link wave-function in the large j limit, believed to be appropriate in the semi-classical limit. We then generalize our considerations to multi-link coherent states, and find that the area law is preserved very generically using our single link wave-function as a building block. Finally, we develop the framework that generates families of multi-link states that preserve the area law while avoiding macroscopic entanglement, the space-time analogue of "Schroedinger cat". We note that these states, defined on a given set of graphs, are the ground states of some local Hamiltonian that can be constructed explicitly. This can potentially shed light on the construction of the appropriate Hamiltonian constraints in the LQG framework.

    The emergy theory was used to analyze the emergy structure of the ecosystem at reclamation area in order to find the problem existed in the reclamation ecosystem through compared with the modern agriculture. The research results show that the proportion of assistant emergy input into the system is higher which indicate that the productivity of reclamation land has not resumed and a lot of assistant emergy needed to improve the productivity. The ecosystem overly depend on chemical fertilizer, which is bad to agricultural ecosystem; the agricultural ecosystem in reclamation area belongs to traditional agriculture because the main power come from manpower and the usage of organic fertilizer is little, through compare the index of emergy with modem agriculture, the value of EYR and ED in reclamation area is less than the modern agriculture.

    To establish base line data and to evaluate the impacts of induced abortion on fertility in Taiwan before and after legalization, and induced abortion prevalence survey was conducted. 12,516 samples of married women age 15-49 were covered to represent all of Taiwan. Bongaarts' model of proximate determinants of fertility is applied to the survey data to analyze the relationships among total fertility rate, total fecundity, and the indices of the proximate determinants on nonmarriage, contraception, induced abortion, and lacatation. The index of contraception appears to have the greatest (47%) effect on the recent decline of total fertility rate (TFR). Contraception also has the greatest effect on fertility decline among different urbanization areas: 45% for large cities; 46% for urbantownships; and 50% for rural areas. The effects of the proportion of married on the fertility of the 3 areas are 45%, 40%, and 40%, respectively. For induced abortion, the effect is 13% in urban townships and 11% in large cities.
